Control being over business by government Essay Example for Free
Control being over business by government Essay What are the arguments for and against, greater control being exercised over business by government? How do these arguments differ between the countries of the group members? We would like to start the answer by an example of USA when they were heavily involved in the industrialization and expansion. People of all different occupations were involved in some part of the industrial revolution. However there was a debate over the government intervening in the building of infrastructure. Chief Justice John Marshall made many landmark court decisions which played a role in defining the business climate that developed during the industrial revolution and strengthened the central governments control over the business. Thus finally the government was involved in the early stages of the industrial revolution. The governments decision of this era laid the ground work of the future U.S. growth of the nation. Without these pro-business decisions, the United states would not have made the change from being agriculturally dependent to the industrialized nation it is today. [www.historyteacher.net/USProjects/myessay21.htm] Hence it sounds better in some situation and it doesnt in some. For example in China, local governments stand passively by as private firms aggressively reject long-standing official right because the government officials in south China are increasingly anxious to shed their responsibility for economic management. Also they fear the risks and dangers associated with the more complete market system that has emerged during the 1990s. As a result, Chinas southern provinces have already begun the process of separating government from business, while, in the north, leading officials emphasize the slogan separate government from enterprises but, fearing slow growth, practice the opposite. [www.pitt.edu/~tgrawski/paper98/china.html] To what extent do you think a change of government in a) UK would affect the business community? b) the countries of group members? It can have a great impact on businesses in UK or in other countries like India, China etc. For example: Regulatory systems can be improved to provide faster access to exploration land and clarification of aboriginal disputes, taxes such as corporate taxes, income taxes etc can be reduced, Business leaders can hope for a complete overhaul of the resource-rich provinces economic structure, Economic growth can be affected by change in government, it is expected that the new government can come up with creative solutions on how to reduce government indebtedness during its term, the new government will aim to solve deficit of balance of payments by boosting production through attracting direct foreign investments, also new government can change the manufacturing scenario in the country like instead of importing products, they can plan to manufacture in their own land which will indirectly reduce the unemployment in the manufacturing field. Also it can provide grant to those regions in which unemployment is high.

With privatization programs still active in several countries in Sub-Saharan Africa, there is a growing debate on effects on economic development. To address such issues the representatives of privatization agencies of different nations established the African Privatization Network (APN) in November 1995. APN aims at promoting the concept of privatization and encouraging its implementation in African countries by sharing legislation and other relevant documentation; studying the nature and scope of privatization in each country according to its special circumstances and needs; and monitoring the process of privatization in Africa, identifying problems and obstacles and offering advice where required. The positive view of privatization suggests that it went ahead, in spite of domestic opposition, because politicians and bureaucrats perceived real benefits to themselves and their supporters. They could influence the sales to their own benefit, while, on the other hand, a more focused public sector improved service delivery. A well functioning private sector is essential for increasing economic growth and thus reducing poverty. Yet international development institutions recommend sophisticated policies to improve the business environment that governments in developing countries cannot successfully implement. The result is often a worsening of private sector performance. The promotion, support, financing, marketing and management of small and medium sized enterprises and industries is the core business of any privatisation programme.

Study on Steps to Christ Essay Example for Free
Study on Steps to Christ Essay He took manââ¬â¢s nature, that He might reach manââ¬â¢s wants. The poorest and humblest were not afraid to approach Him. Such is the character of Christ as revealed in His life. This is the character of God. It was to redeem us that Jesus lived and suffered and died. He became a Man of Sorrows, that we might be made partakers of everlasting joy. But this great sacrifice was not made in order to create in the Fatherââ¬â¢s heart a love for man, not make Him willing to save. No, no! God so loved the world, that He gave His only-begotten Son. John 3:16. The Father loves us, not because of the great propitiation, but He provided the propitiation because He loves us. None but the Son of God could accomplish our redemption. What a value this places upon man! Through transgression the sons of man become subjects of Satan. Through faith in the atoning sacrifice of Christ the sons of Adam may become the sons of God. The matchless love of God for a world that did not love Him! The thought has a subduing power upon the soul and brings the mind into captivity to the will of God. Man was originally endowed with noble powers and a well-balanced mind. He was perfect in his being, and in harmony with God. His thoughts were pure, his aims holy. But through disobedience, his powers were perverted, and selfishness took the place of love. His nature became so weakened through transgression that it was impossible for him, in his own strength, to resist the power of evil. It is impossible for us, of ourselves, to escape from the pit of sin in which we are sunken. Our hearts are evil, and we cannot change them. There must be a power working from within, a new life from above, before men can be changed from sin to holiness. That power is Christ. His grace alone can quicken the lifeless faculties of the soul, and attract it to God, to holiness. To all, there is but one answer, Behold the Lamb of God, which taketh away the sin of the world (John 1:29). Let us avail ourselves of the means provided for us that we may be transformed into His likeness, and be restored to fellowship with the ministering angels, to harmony and communion with the Father and the Son. How shall a man be just with God? How shall the sinner be made righteous? It is only through Christ that we can be brought into harmony with God, with holiness; but how are we to come to Christ? Repentance includes sorrow for sin and a turning away from it. We shall not renounce sin unless we see its sinfulness; until we turn away from it in heart, there will be no real change in the life. But when the heart yields to the influence of the Spirit of God, the conscience will be quickened, and the sinner will discern something of the depth and sacredness of Godââ¬â¢s holy law, the foundation of His government in heaven and on earth. Conviction takes hold upon the mind and heart. The prayer of David, after his fall, illustrates the nature of true sorrow for sin. His repentance was sincere and deep. There was no effort to palliate his guilt; no desire to escape the judgment threatened, inspired his prayer. David saw the enormity of his transgression; he saw the defilement of his soul; he loathed his sin. It was not for pardon only that he prayed, but for purity of heart. He longed for the joy of holiness, to be restored to harmony and communion with God. A repentance such as this, is beyond the reach of our own power to accomplish; it is obtained only from Christ. Christ is ready to set us free from sin, but He does not force the will. If we refuse, what more can He do? Study Godââ¬â¢s Word prayerfully. As you see the enormity of sin, as you see yourself as you really are, do not give up in despair. It was sinners that Christ came to save. When Satan comes to tell you that you are a great sinner, look to your Redeemer and talk of His merits. Acknowledge your sin, but tell the enemy that Christ came into the world to save sinners and that you may be saved (1 Tim. 1:15). He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy. Proverbs 28:13. The conditions of obtaining mercy of God are simple and just and reasonable. Confess your sins to God, who only can forgive them, and your faults to one another. Those who have not humbled their souls before God in acknowledging their guilt, have not yet fulfilled the first step of acceptance. We must be willing to humble our hearts and comply with the conditions of the Word of truth. The confession that is the outpouring of the inmost soul finds its way to the God of infinite pity. True confession is always of a specific character, and acknowledges particular sins. All confession should be definite and to the point. It is written, If we confess our sins, He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness (1 John 1:9). Godââ¬â¢s promise is, Ye shall seek Me, and find Me, when ye shall search for Me with all your heart. Jeremiah 29:13. The whole heart must be yielded, or the change can never be wrought in us by which we are to be restored to His likeness. The warfare against self is the greatest battle that was ever fought. The yielding of self, surrendering all to the will of God, requires a struggle; but the soul must submit to God before it can be renewed in holiness. In giving ourselves to God, we must necessarily give up all that would separate us from Him. There are those who profess to serve God, while they rely upon their own efforts to obey His law, to form a right character, and secure salvation. Their hearts are not moved by any deep sense of the love of Christ, but they seek to perform the duties of the Christian life as that which God requires of them in order to gain heaven. Such religion is worthless. When Christ dwells in the heart, the soul will be so filled with His love, with the joy of communion with Him, that it will cleave to Him; and in the contemplation of Him, self will be forgotten. Love to Christ will be the spring of action. Such do not ask for the lowest standard, but aim at perfect conformity to the will of their Redeemer. Do you feel that it is too great a sacrifice to yield all to Christ? Ask yourself the question, What has Christ given for me? The Son of God gave allââ¬âlife and love and sufferingââ¬âfor our redemption. And can it be that we, the unworthy objects of so great love, will withhold our hearts from Him? What do we give up, when we give all? A sin-polluted heart, for Jesus to purify, to cleanse by His own blood, and to save by His matchless love. And yet men think it hard to give up all! God does not require us to give up anything that it is for our best interest to retain. In all that He does, He has the well-being of His children in view. Many are inquiring, How am I to make the surrender of myself to God? You desire to give yourself to Him, but you are weak in moral power, in slavery to doubt, and controlled by the habits of your life of sin. Your promises and resolutions are like ropes of sand. You cannot control your thoughts, your impulses, your affections. The knowledge of your broken promises and forfeited pledges weakens your confidence in your own sincerity, and causes you to feel that God cannot accept you; but you need not despair. What you need to understand is the true force of the will. This is the governing power in the nature of man, the power of decision, or of choice. Everything depends on the right action of the will. The power of choice God has given to men; it is theirs to exercise. You cannot change your heart, you cannot of yourself give to God its affections; but you can choose to serve Him. You can give Him your will; He will then work in you to will and to do according to His good pleasure. Thus your whole nature will be brought under the control of the Spirit of Christ; your affections will be centered upon Him, your thoughts will be in harmony with Him. Desires for goodness and holiness are right as far as they go; but if you stop here, they will avail nothing. Many will be lost while hoping and desiring to be Christians. They do not come to the point of yielding the will to God. They do not now choose to be Christians. Through the right exercise of the will, an entire change may be made in your life. You will have strength from above to hold you steadfast, and thus through constant surrender to God you will be enabled to live the new life, even the life of faith. As your conscience has been quickened by the Holy Spirit, you have seen something of the evil of sin, of its power, its guilt, its woe; and you look upon it with abhorrence. It is peace that you need. You have confessed your sins, and in heart put them away. You have resolved to give yourself to God. Now go to Him, and ask that He will wash away your sins and give you a new heart. Then believe that He does this because He has promised. The gift which God promises us, we must believe we do receive, and it is ours. You are a sinner. You cannot atone for your past sins; you cannot change your heart and make yourself holy. But God promises to do all this for you through Christ. You believe that promise. You confess your sins and give yourself to God. You will to serve Him. Just as surely as you do this, God will fulfill His Word to you. If you believe the promise,ââ¬âGod supplies the fact. Do not wait to feel that you are made whole, but say, I believe it; it is so, not because I feel it, but because God promised. ââ¬âSummary of all the key points in Steps to Christ, pp. 9-51, in the authorââ¬â¢s own words. Part Two ââ¬â How Can I Remain True to God? Jesus says, What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them (Mark 11:24). There is a condition to this promiseââ¬âthat we pray according to the will of God. But it is the will of God to cleanse us from sin, to make us His children, and to enable us to live a holy life. So we may ask for these blessings, and believe that we receive them, and thank God that we have received them. Henceforth you are not your own; you are bought with a price. Through this simple act of believing God, the Holy Spirit has begotten a new life in your heart. You are a child born into the family of God, and He loves you as He loves His Son. Now that you have given yourself to Jesus, do not draw back, do not take yourself away from Him, but day by day say, I am Christââ¬â¢s; I have given myself to Him; and ask Him to give you His Spirit and keep you by His grace. As it is by giving yourself to God, and believing Him, that you become His child, so you are to live in Him. Here is where thousands fail; they do not believe that Jesus pardons them personally, individually. They do not take God at His Word. It is the privilege of all who comply with the conditions to know for themselves that pardon is freely extended for every sin. Put away the suspicion that Godââ¬â¢s promises are not meant for you. They are for every repentant transgressor. Look up, you that are doubting and trembling; for Jesus lives to make intercession for us. Thank God for the gift of His dear Son. If any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. 2 Corinthians 5:17. A person may not be able to tell the exact time or place, or trace all the chain of circumstances in the process of conversion; but this does not prove him to be unconverted. A change will be seen in the character, the habits, the pursuits. The contrast will be clear and decided between what they have been and what they have become. Who has the heart? With whom are our thoughts? Of whom do we love to converse? Who has our warmest affections and our best energies? If we are Christââ¬â¢s, our thoughts are with Him. There is no evidence of genuine repentance unless it works reformation. The loveliness of the character of Christ will be seen in His followers. It was His delight to do the will of God. There are two errors against which the children of God especially need to guard: The first is that of looking to their own works, trusting to anything they can do, to bring themselves into harmony with God. All that man can do without Christ is polluted with selfishness and sin. It is the grace of Christ alone, through faith, which can make us holy. The opposite and no less dangerous error is that belief in Christ releases men from keeping the law of God; that since by faith alone we become partakers of the grace of Christ, our works have nothing to do with our redemption. Obedience is the fruit of faith. Righteousness is defined by the standard of Godââ¬â¢s holy law, as expressed in the ten commandments (Exo. 20:3-20). That so-called faith in Christ, which professes to release men from the obligation of obedience to God, is not faith, but presumption. The condition of eternal life is now just what it always has been,ââ¬âjust what it was in paradise before the fall of our first parents,ââ¬âperfect obedience to the law of God, perfect righteousness. If eternal life were granted on any condition short of this, then the happiness of the whole universe would be imperiled. The way would be open for sin, with all its train of woe and misery, to be immortalized. Christ changes the heart. He abides in your heart by faith. You are to maintain this connection with Christ by faith and the continual surrender of your will to Him; and so long as you do this, He will work in you to will and to do according to His good pleasure. The closer you come to Jesus, the more faulty you will appear in your own eyes; for your vision will be clearer. This is evidence that Satanââ¬â¢s delusions are losing their power. No deep-seated love for Jesus can dwell in the heart that does not realize its own sinfulness. The soul that is transformed by the grace of Christ will admire His character. A view of our sinfulness drives us to Him who can pardon; and when the soul, realizing its helplessness, reaches out after Christ, He will reveal Himself in power. The more our sense of need drives us to Him and to the Word of God, the more exalted views we shall have of His character, and the more fully we shall reflect His image. The change of heart by which we become children of God is in the Bible spoken of as birth. Again it is compared to the germination of the good seed sown by the husbandman. It is God who brings the bud to bloom and the flower to fruit. It is by His power that the seed develops. As the flower turns to the sun, that the bright beams may aid in perfecting its beauty and symmetry, so should we turn to the Sun of Righteousness, that heavenââ¬â¢s light may shine upon us, that our character may be developed into the likeness of Christ. Do you ask, How am I to abide in Christ? In the same way as you received Him at first. As ye have therefore received Christ Jesus the Lord, so walk in Him. Colossians 2:6. By faith you became Christââ¬â¢s, and by faith you are to grow up in Himââ¬âby giving and taking. You are to give all,ââ¬âyour heart, your will, your service,ââ¬âgive yourself to Him to obey all His requirements; and you must take allââ¬âChrist, the fullness of all blessing, to abide in your heart, to be your strength, your righteousness, your everlasting helperââ¬âto give you power to obey. Consecrate yourself to God in the morning; make this your very first work. Let your prayer be, Take me, O Lord, as wholly Thine. I lay all my plans at Thy feet. Use me today in Thy service. Abide with me, and let all my work be wrought in Thee. This is a daily matter. Each morning consecrate yourself to God for that day. Surrender all your plans to Him, to be carried out or given up as His providence shall indicate. Thus day by day you may be giving your life into the hands of God, and thus your life will be molded more and more after the life of Christ. A life in Christ is a life of restfulness. There may be no ecstasy of feeling, but there should be an abiding, peaceful trust. When the mind dwells upon self, it is turned away from Christ, the source of strength and life. Hence, it is Satanââ¬â¢s constant effort to keep the attention diverted from the Saviour and thus prevent the union and communion of the soul with Christ. When Christ took human nature upon Him, He bound humanity to Himself by a tie of love that can never be broken by any power save the choice of man himself. Satan will constantly present allurements to induce us to break this tieââ¬âto choose to separate ourselves from Christ. But let us keep our eyes fixed upon Christ, and He will preserve us. Looking unto Jesus, we are safe. Nothing can pluck us out of His hand. All that Christ was to the disciples, He desires to be to His children today. Jesus prayed for us, and He asked that we might be one with Him, even as He is one with the Father. What a union is this! Thus, loving Him and abiding in Him, we shall grow up into Him in all things, which is the head, even Christ (Ephesians 4:15). God is the source of life and light and joy to the universe. Wherever the life of God is in the hearts of men, it will flow out to others in love and blessing. Our Saviourââ¬â¢s joy was in the uplifting and redemption of fallen men. For this He counted not His life dear to Himself, but endured the cross, despising the shame. When the love of Christ is enshrined in the heart, like sweet fragrance it cannot be hidden. Love to Jesus will be manifested in a desire to work as He worked for the blessing and uplifting of humanity. It will lead to love, tenderness, and sympathy toward all the creatures of our heavenly Fatherââ¬â¢s care. Those who are the partakers of the grace of Christ will be ready to make any sacrifice, that others for whom He died may share the heavenly gift. They will do all they can to make the world better for their stay in it. This spirit is the sure outgrowth of a soul truly converted. No sooner does one come to Christ than there is born in his heart a desire to make known to others what a precious friend he has found in Jesus. If we have tasted and seen that the Lord is good, we shall have something to tell. We shall seek to present to others the attractions of Christ and the unseen realities of the world to come. There will be an intensity of desire to follow in the path that Jesus trod. And the effort to bless others will react in blessings upon ourselves. Those who thus become participants in labors of love are brought nearest to their Creator. The spirit of unselfish labor for others gives depth, stability, and Christlike loveliness to the character, and brings peace and happiness to its possessor. Strength comes by exercise. We need not go to heathen lands, or even leave the narrow circle of the home, if it is there that our duty lies, in order to work for Christ. With a loving spirit we may perform lifeââ¬â¢s humblest duties unto the Lord (Col. 3:23). If the love of God is in the heart, it will be manifested in the life. You are not to wait for great occasions or to expect extraordinary abilities before you go to work for God. The humblest and poorest of the disciples of Jesus can be a blessing to others. Many are the ways in which God is seeking to make Himself known to us and bring us into communion with Him. If we will but listen, Nature speaks to our senses without ceasing. Godââ¬â¢s created works will teach us precious lessons of obedience and trust. No tears are shed that God does not notice. There is no smile that He does not mark. If we would but fully believe this, all undue anxieties would be dismissed. Our lives would not be so filled with disappointment as now; for everything, whether great or small, would be left in the hands of God. God speaks to us through His providential works and through the influence of His Spirit upon the heart. God speaks to us in His Word. Here we have in clearer lines the revelation of His character, of His dealings with men, and the great work of redemption. Fill the whole heart with the words of God. They are the living water, quenching your burning thirst. They are the living bread from heaven. The theme of redemption is one that the angels desire to look into; it will be the science and the song of the redeemed throughout the ceaseless ages of eternity. Is it not worthy of careful thought and study now? As we meditate upon the Saviour, there will be a hungering and thirsting of soul to become like Him whom we adore. The Bible was written for the common people. The great truths necessary for salvation are made as clear as noonday. There is nothing more calculated to strengthen the intellect than the study of the Scriptures. But there is little benefit derived from a hasty reading of the Bible. One passage studied, until its significance is clear to the mind and its relation to the plan of salvation is evident, is of more value than the perusal of many chapters with no definite purpose in view and no positive instruction gained. Keep your Bible with you. As you have opportunity, read it; fix the texts in your memory. We cannot obtain wisdom without earnest attention and prayerful study. Never should the Bible be studied without prayer. Before opening its pages, we should ask for the enlightenment of the Holy Spirit, and it will be given. Angels from the world of light will be with those who in humility of heart seek for divine guidance. How must God esteem the human race, since He gave His Son to die for them and appoints His Holy Spirit to be manââ¬â¢s teacher and continual guide! Through nature and revelation, through His providence, and by the influence of His Spirit, God speaks to us. But these are not enough; we need also to pour out our hearts to Him. In order to commune with God, we must have something to say to Him concerning our actual life. Prayer is the opening of the heart to God as to a friend. Not that it is necessary in order to make known to God what we are, but in order to enable us to receive Him. Prayer does not bring God down to us, but brings us up to Him. Our heavenly Father waits to bestow upon us the fullness of His blessing. What a wonder it is that we pray so little! God is ready and willing to hear the sincere prayer of the humblest of His children. What can the angels of heaven think of poor helpless human beings, who are subject to temptation, when Godââ¬â¢s heart of infinite love yearns toward them, ready to give them more than they can ask or think, and yet they pray so little and have so little faith? The darkness of the evil one encloses those who neglect to pray. The whispered temptations of the enemy entice them to sin; and it is all because they do not make use of prayer. Yet prayer is the key in the hand of faith to unlock heavenââ¬â¢s storehouse, where are treasured the boundless resources of Omnipotence. There are certain conditions upon which we may expect that God will hear and answer our prayers: One is that we feel our need of help from Him. If we regard iniquity in our hearts, if we cling to any known sin, the Lord will not hear us; but the prayer of the penitent, contrite soul is always accepted. When all known wrongs are righted, we may believe that God will answer our petitions. Another element of prevailing prayer is faith. When our prayers seem not to be answered, we are to cling to the promise; for the time of answering will surely come, and we shall receive the blessing we need most. But to claim that prayer will always be answered in the very way and for the particular thing that we desire, is presumption. When we come to God in prayer, we should have a spirit of love and forgiveness in our own hearts. Perseverance in prayer has been made a condition of receiving. We must pray always if we would grow in faith and experience. We should pray in the family circle, and above all we must not neglect secret prayer, for this is the life of the soul. Family or public prayer alone is not sufficient. Secret prayer is to be heard only by the prayer-hearing God. There is no time or place in which it is inappropriate to offer up a petition to God. In the crowds of the street, in the midst of a business engagement, we may send up a petition to God and plead for divine guidance. Let the soul be drawn out and upward, that God may grant us a breath of the heavenly atmosphere. We may keep so near to God that in every unexpected trial our thoughts will turn to Him as naturally as the flower turns to the sun. Keep your wants, your joys, your sorrows, your cares, and your fears before God. You cannot burden Him; you cannot weary Him. He is not indifferent to the wants of His children. We sustain a loss when we neglect the privilege of associating together to strengthen and encourage one another in the service of God. If Christians would associate together, speaking to each other of the love of God and the precious truths of redemption, their own hearts would be refreshed and they would refresh one another. We must gather about the cross. Christ and Him crucified should be the theme of contemplation, of conversation, and of our most joyful emotion. We should keep in our thoughts every blessing we receive from God, and when we realize His great love we should be willing to trust everything to the hand that was ailed to the cross for us. The soul may ascend nearer heaven on the wings of praise. As we express our gratitude, we are approximating to the worship of the heavenly hosts. Many are at times troubled with the suggestions of skepticism. God never asks us to believe, without giving sufficient evidence upon which to base our faith. Disguise it as they may, the re al cause of doubt and skepticism, in most cases, is the love of sin. We must have a sincere desire to know the truth and a willingness of heart to obey it.

Reducing Anxiety among Radiology Patients
Reducing Anxiety among Radiology Patients INTRODUCTION Background of the Study As the technologic complexity of radiologic procedures has grown, the emotional reactions of patients to imaging procedures have become more prominent, and interaction between patients and the staff of diagnostic radiology units has become more important 1. Like the smaller number of patients surveyed by Monics et al 2 after undergoing a variety of radiologic procedures at a teaching hospital, patients in this sample were more concerned with explanations of procedures and results, and with factors affecting their physical comfort, than with the competency of the staff or their own convenience. Patients awaiting therapeutic procedures commonly report anxiety 1, fears about the unknown, pain, possibility of further interventions, complications, destruction of body image, disruption of life plans, loss of control, disability, and loss of life 2. Most of the time, one might assume that diagnostic tests, which typically carry fewer risks than invasive therapeutic procedures, would create less distress. Diagnostic tests, however, inherently harbor uncertainty, which can be a potent stressor and has been linked to poor coping with health-related issues, as well as poor adaptation and recovery 4. Hence, the conduct of this study in this aspect will assess the level of distress in patients awaiting radiological procedure particularly in breast , transvaginal and scrotal ultrasound. The study will also provide effective protocol in the conduct of giving information to patients. Review of Related Literature Waiting room distress can impact patients and radiology resources by taxing ââ¬Å"departmental resources in terms of appointment cancellations, patientsââ¬â¢ lack of cooperation, extended room times, increased medication use, prolonged recovery and inability to complete imaging procedures well or at all, with adverse impact on both image quality and reimbursement,â⬠wrote Nicole Flory, PhD, of the department of radiology at Beth Israel Deaconess Medical-Harvard Medical School in Boston, and colleagues 5. Attention to patientââ¬â¢s acute distress before and during procedures is important because distress may cause hemodynamic instability, procedural complications, and other adverse events 6. As mentioned by KrantzDS et al 7, stress and anxiety may cause adverse events through elevated levels of blood pressure, heart rate, coronary constriction, and stress hormones. Jangland et al 8 found that, among those patients who complained about care and increased anxiety, the most common complaints were insufà ¯Ã ¬Ã cient information, inadequate respect, and insufà ¯Ã ¬Ã cient empathy. In the study of Nicole Flory, et al 5 they concluded that uncertainty of diagnosis can weigh heavily on the patient, and perceptions of what medical personnel may consider ââ¬Å"minorâ⬠do not necessarily reflect the patientââ¬â¢s experience. Training medical personnel in how to communicate with these patients and to assuage their distress promises not only to relieve the patientsââ¬â¢ distress but also to positively affect departmental resources. In our literature search, we identified no previous studies of topics related to anxiety reduction prior to radiologic procedure. Also, no particular studies were taken in comparative assessment of psychological distress in conjunction with imaging procedures using the standard verbal explanation against the audio visual presentation. This study therefore will take advantage of the availability of preprocedural surveys from prospective randomize control trials that will be performed in department of radiology with patients at various radiologic procedures using Hospital Anxiety and Depression Scale (HADS). Research questions What is the prevalence of anxiety and depression among patients referred for breast, transvaginal and scrotal ultrasound using the adaptive verbal pre-procedural briefing versus with complimentary audio visual presentation? What is the level of anxiety and depression among patients referred for breast, transvaginal and scrotal ultrasound using the adaptive verbal pre-procedural briefing versus with additional audio visual presentation? Is there any differences between anxiety and depression rate in patients undergoing breast, transvaginal and scrotal ultrasound using the adaptive verbal pre-procedural briefing versus with audio visual presentation?à Significance of the study In the current set-up of our department in radiology, at most three residents are assigned to ultrasound section, catering 60 patients per day with resident to patient ratio of 1:30 in an 8 hour-shift. This would only give the resident 8 minutes per patient to do his/her doctor-patient interaction. All patients under fasting, are the most priority causing all other patient to have a waiting time of about an hour or two for her/him to be served, and this where the patients for breast, scrotal and transvaginal falls. These procedures also give more anxiety and distress if not explained well by their respective doctors because of its very intimate approach. With this existing reality, having an audio-visual presentation as an additional tool of information might help alleviate patientââ¬â¢s anxiety and distress. This assessment is a first step in evaluating the adaptive verbal pre-procedural protocol in the radiology department with that of another additional audio-visual presentation, and the results of such an evaluation then can help guide specific interventions toward better outcomes. Objectives General objective This study aims to compare the effectiveness of the additional audio-visual briefing presentation versus the adapted pre-procedural verbal briefing only among patients referred for breast, transvaginal and scrotal ultrasound in Department of Radiological and Imaging Sciences at Southern Philippines Medical Center, Davao City in reducing the level of anxiety/depression using Hospital Anxiety and Depression Scale (HADS) model. Specifically, this study aims to determine the following: a. Demographic and clinical profile of patients who will underwent breast, scrotal, transvaginal ultrasound. b. To compare the effectiveness of adapted verbal pre-procedural briefing against with additional audio-visual presentation in decreasing the anxiety/depression level among patients referred for imaging study. c. To suggest recommendation to policy makers and professionals for adoption of creative ways to control or minimize this phenomena. II. MATERIALS AND METHODS Study Setting: The study will be conducted at the Department of Radiological and Imaging Sciences waiting section at Southern Philippines Medical Center, Davao City. The study will be done over a period of three months (April to June 2014) Study Participants All patients referred to the Department of Radiology and Imaging Sciences facility at Southern Philippines Medical Center for breast, transvaginal and scrotal ultrasound, that is qualified to join in the study. Below are the inclusion and the exclusion criteria for patients who are candidates for the study. Inclusion criteria Adult patients (18 ââ¬â 65 years old) who will give their consent for the study. Understands English language Patients who do not meet any criteria for a mental health disorder using the Global Mental Health Assessment Tool (GMHAT) of the World Health Organization Patient should have mild or moderate levels of anxiety at the start of the trial Ambulatory Conscious Exclusion criteria All patients who will undergo breast, transvaginal and scrotal procedure that will not give their consent for the study and will not meet the inclusion criteria. Baseline Data Collection Consents for the research study will be obtained by the researcher between the ages of approximately 18 and 65 years of age. All consecutive patients who had completed their consent from April to July 2014 will be evaluated for study eligibility by the researcher. All patients who will participate will undergo Global Mental Health Assessment Tool (GMHAT) of the World Health Organization to exclude patients having overt mental disorder and will be advised to seek professional help. A randomized selection of patients will be done wherein they are asked to blindly select which group they will fall by drawing lots. First group will undergo the usual verbal pre-procedural briefing while the second group will receive the additional audio-visual presentation. The researcher will ask consecutive eligible patients to participate in a study in which the level of anxiety and depression will be assessed prior to ultrasound procedure. Both groups will be handed identical stacks of psychological questionnaire: the Hospital Anxiety and Depression Scale(Appendix 1) under the supervision of the investigator. Patients will be at liberty with regard to the sequence in which they would fill out the questionnaires. Another identical stack of HADS questionnaires will be given to the participants after the end of the intervention still under the supervision of the investigator. Outcome Measures Socio-demographic questionnaires The demographic information includes age, gender, education and occupation. Hospital Anxiety and Depression Scale(HADS): The HADS is a screening tool for anxiety and depression in non-psychiatric clinical populations. The scale consists of 14 items (7 each for anxiety and depression). Each item is rated on a four point scale ranging from 0 (not at all) to 3 (very often). Responses are based on the relative frequency of symptoms over the preceding week. Possible scores range from 0 to 21 for each subscale. An analysis of scores on the two subscales supported the differentiation of each mood state into four ranges: ââ¬Ëmild casesââ¬â¢ (scores 8-10), ââ¬Ëmoderate casesââ¬â¢ (scores 11-15), and ââ¬Ësevere casesââ¬â¢ (scores 16 or higher). HADS was validated by group of researchers (Ingvar Bjelland, Alv A. Dahl, Tone Tangen Haug, Dag Neckelmann) from Department of Public Health and Primary Health Care, Section for Preventive Medicine and Department of Psychiatry of Norway using Cronbalchââ¬â¢s alpha. In their study, the sensitivity and specificity for HADS of approximately 0.80 were very similar to the sensitivity and specificity achieved by the General Health Questionnaire (GHQ). Hence the review confirmed the assumption that HADS is a questionnaire that performs well in screening for the separate dimensions of anxiety and depression and caseness of anxiety disorders and depression in patients from nonpsychiatric hospital clinics9. Audio Visual Presentation: The video will run for 10 minutes and must answer the following questions of: a. WHAT IS THE PROCEDURE? b. WHY IS THE PROCEDURE NECESSARY? c. HOW IS THE PROCEDURE DONE? d. WHAT ARE THE RISKS AND COMPLICATIONS OF THE PROCEDURE? The video will be in full English language. The video will be validated by a Mass Communication professor by issuing a certificate. The video will be presented to at least 10 randomized selected persons outside the DORIS personnel before the actual test will be done. At the end of the video they must able to answer the above questions. During the actual test, video will be presented in groups through television in a separate room. Data Handling and Analyses The data will be collected directly from the patients by using HADS Scale questionnaires in DORIS at SPMC. Detailed information about the study will be given to each participant using English language and consent to participate will be obtained. Over viewing of the questionnaire will be the first step, prior to data entry; this will be followed by designing an entry model using the computer Statistical Package for Social Science SPSS. The coded questionnaires will be entered into the computer by the researcher. Data cleaning will be done through checking out a random number of the questionnaires and through exploring descriptive statistics frequencies for all variables. All suspected or missed values will be checked by revising the available sheets. The researcher will use Statistical Package for Social Science SPSS to analyze the research questions by using Chi square, ANOVA, and t test to answer the objectives. Also, the researcher used descriptive statistics to explore frequencies of all variables. Statistically significant values are considered at P values is equal or less than 0.05. Sample Size Considerations The sample size that will be used in the study is the total summation of the patients who will undergo breast, transvaginal and scrotal ultrasound who will give their consent and within the inclusion criteria from April to July of 2014.
WItchcraft :: essays research papers
Witchcraft à à à à à In general witchcraft is sorcery, the magical manipulation of the supernormal forces through the use of spells, and the conjuring or invoking of spirits. Wicca is the most common witchcraft. During the middle ages and the renaissance, it was defined as evil magic. This is the very reason Joan of Arc was burned at the stake; she was accused of being a witch. Although many think that it is a religion that worships the devil, Wicca does not have anything to do with worshiping the devil or Christianity. The most common form of witchcraft is done with the use of spells. To set a spell, the person doing it will set up an altar/table in which to place the candles and symbols on. The spells consist of words that can either be chanted or inscribed in something. The candles are used to direct the spell towards a specific purpose, such as: pink-love, white-healing and peace, and black-death. These colors can be used for different meanings; however, these are the standard mea nings. There are many other colors out there with their own unique meanings, like if a spell was being set on a person; a candle that was their favorite color could be used. The symbols used consist of charms, pictures, flowers and belongings depending on the spell being set. These symbols must represent the spell and they cannot just be anything done quickly without thought. For example, if the person were trying to make their friend heal from a sickness a picture of the person or something that represents them would work. Very experienced witches use potions that consist of a complicated formula and weird recipes. Almost anything one could think of could be in a witchââ¬â¢s potion, such as bat blood, human blood, eyeballs, herbs, spices, etc. In order to be able to work this magic one must acquire enough knowledge through meditation, and other acts of complete focus and research, others are just born with the natural power. Most people who have this power set spells for the goo d and others well-being; for, any evil spell one sets will come back on them times three. This law is called the power of three times three, which must be known before there are any attempts of setting spells. Although this seems like a great and easy thing, it is very dangerous. The words in the spell are taken literally, for instance if your spell was set to make someone leave you alone for good, it could cause the person to die.

The Possessive - Empty Nest :: Possessive Essays
The Possessive - Empty Nestà à A nest lies empty on top a forked branch of an old oak tree. Last spring children play, young lovers whisper into each others ear, and the elderly relax under that tree. When they do, they can hear the quiet chirps of little hungry baby blue-jays. The little blue-jays chirp until the mother blue-jay returns with food . Afterwards, one attempts to fly and fall out of the nest. The mother blue-jay then quickly swoops down and catches the little one before he hits the ground. The baby jay can always depend on his mother when he needs her, but she knows that one day he will no longer rely on her. On that day, instead of plummeting to his death, the young blue-jay will spread his wings and fly away. He will fly straight into the setting sun never looking back. Slowly all of the young will fly away and leave the mother alone in the nest. However, mothers do not always handle this situation calmly. In "The Possessive," Sharon Olds conjures intense images of betrayal and utilizes war as a me taphor to express a mother's emotion as her daughter leaves the nest. The poem reflects the separation anxiety the mother undergoes as she witnesses her daughter mature and distance herself. à To set the mood of the poem, Olds relies heavily on imagery to create the effect. The mother feels betrayed as she watches her daughter slip away from her. Small trivial acts like a simple haircut evoke strong images of discomfort. The barber is described as a "knife grinder" (4) sharpening the edges of her daughter's hair as if they are weapons. Olds slips words such as "slice" and "blade", which thrust images of separation into the mind of the reader. She follows these images with sharp edges and cold steel, and then she tops it off with a blazing, red fire The strong intense color red spills over the lines of the poem as blood of soldiers in a heated battle. The vibrant nature of the color red attracts the human eye creating intense emotions. The intense images express the intensity of the mother's emotions. The imagery in this poem aches the pain and discomfort the mother experiences as mother and daughter prepare for a battle. à The images create the war metaphor presence in the poem.

Herpes Simplex Virus
Herpes Simplex Virus Type 1 Infection at the Molecular Level Research Paper Virology 24 November 2008 Abstract Herpes simplex virus type 1 (HSV-1) infection is widespread and causes significant disease in humans. The structure, epidemiology, pathogensis and immune response are examined in this review, as well as specific ways to reduce and eliminate pathology and related diseases. The virus naturally infects mucosal areas and begins the search for its target host cell. Upon binding to the host cell membrane via teams of glycoproteins, the virion is then phagocytosed.Soon the nucleus is seized and all regular host cell mechanisms are shut off. Replication of HSV-1 is specific encoding immediate early, early and late genes. Once the virus replication process is complete the virus exits epithelial cells near the site of infection through a process known as cell lysis. Sensory neurons are the specific target of HSV-1, where it can then travel to the trigeminal ganglia (TG) stoma via neur onal microtubular networks. Both innate and adaptive immune systems respond to the infection with various antibodies, interleukins and interferons.Once the virion reaches the nervous system, the immune responses are unable to detect it although they try to contain it as best they can. HSV-1 enters a latent stage, usually via latent associated transcripts, not causing pathogenesis but unable to fight off by means of the host immune system. Following a stressful situation or similarly UV activation, HSV-1 travels back down nerve fibers to re-infect cells near the original site of infection. This process is known to continue throughout the lifespan of the infected individual, normally without fatalities.When the host immune response is unable to contain the virus in the TG, several associated diseases such as encephalitis and keratits result. Genes involved with virus replication and host genes, to eliminate the virus, have been maneuvered to cause reverse effects and are currently use d as antivirals. Although no vaccine has been approved for use against HSV-1, various attempts have been made. This research paper defines the virus infection at a molecular level as well as demonstrates modifications of the virus genes to cause reverse effects and investigates just a few of the diseases connected with HSV-1.Introduction Herpes simplex viruses type 1 and 2 are well known members of the family Herpesviridae, subfamily Alphaherpesvirinae, which cause lifelong, latent infection in humans. Herpes simplex virus type 1 (HSV-1) typically remains the cause of cold sores, gingivostomatitis, and skin lesions in the orofacial area, as well as many rare but fatal conditions (1). Herpes simplex virus type 2 (HSV-2) is primarily associated with genital area infection. Worldwide, approximately one third of people display clinical manifestations of HSV-1 infection (2).HSV-1 is neurotropic, infecting multiple cell types but establishing latency in the trigeminal ganglia (TG). HSV-1 reactivates, in response to certain stimuli such as emotional or physical stress or UV light, and is transported along nerve fibers to mucosal or cutaneous regions (1). Infected cells show signs of the nucleus changing shape and nucleolus displacement with a formation of multinucleated giant cells. Cells degenerate, lyse and vesicles of fluid containing the virus locate between the epidermis and dermal layer of the skin forming a lesion (2).Although HSV-1 infects a large percentage of the population, few actually show symptoms of disease. HSV Structure and Genome HSV-1 is an enveloped double stranded DNA (dsDNA) virus consisting of four elements. First, an outer envelope with glycoprotein spikes on its surface. Second, a tegument layer including several viral proteins important during HSV-1 infection. Third, an iscosahedral capsid surrounding the last compartment, the electron opaque core containing the dsDNA genome wrapped as a spool. The envelope is made up of 13 different viral g lycoproteins embedded in a lipid bilayer.The viral genome of 152 kb, encode the majority of the proteins of the mature virion. Covalently linked L (long) and S (short) components are broken down into unique long (Ul), flanked by ab and bââ¬â¢aââ¬â¢ repeated segments, and unique short (Us), flanked by ac and cââ¬â¢aââ¬â¢ repeated segments. Homologous recombination between terminal repeats results in four linear isomers at equimolar concentrations (see figure 1). All four isomers, including P (prototype), IL (inversion of the L component), IS (inversion of the S component) and ISL (inversion of both the S and the L component), encode 90 unique transcription genes essential for viral replication (3).HSV Replication Infection is first initialted by the attachment to the host cell glucosaminoglycans, usually heparin sulphate and chondroiton sulphate, with viral glycoprotein C (gC). This bond results in at least five glycoprtoeins, gB, gC, gD, gH and gL, binding to other cell surface receptors, such as Herpesvirus entry mediator or nectin 1? or ? (4). Fusion of the viral envelope follows, and the de-enveloped tegument capsid is transported to the nuclear pores via the microtubular network, where DNA is released into the nucleus.Nuclear pore complex accepts the viral DNA from the capsid, minimizing the diffusion of DNA to the cytoplasm, and the transfer is completed by nuclear pore proteins (5). The viral genome circularizes upon entering the nucleus, and transcription of the five immediate early genes (IE) is done by the host RNA polymerase II. Among the IE genes are ICP0, ICP4, ICP22, ICP27 and ICP47. Host transcription, RNA splicing and transport are inhibited during replication, known as host cell shut off. Early (E) viral genes encode enzymes in nucleotide metabolism and viral DNA replication and require the presence of IE genes.Viral E gene products, including viral DNA polymerase, single-stranded DNA-binding protein, origin binding protein and DNA helicase-primase, assemble on the parental viral DNA and start DNA synthesis in replication compartments. Three DNA replication origins bind by viral origin-binding protein, separate the DNA strands and initiate viral DNA synthesis. Expression of the late (L) genes begins and produces structural components of the virion. Capsid assembly occurs in the cytoplasm and the associated proteins are then transported to the nucleus.Progeny DNA concatamers are cleaved into monomers and are inserted into the capsid. Cleavage and packing of HSV-1 genome requires two cis-acting elements, pac1 and pac2. Next the nucleocapsid matures and egress by passing through the Golgi apparatus with the tegument layer and the virion envelope. (3) HSV Latency After infection of the mucosa or epithelial abrasion, HSV-1 enters sensory neurons near the site of infection and the tegument and nucleocapsid travel by retrograde axonal transport to cell neuronal soma releasing viral DNA and VP16, when the virus may en ter lytic replication or the latent state.Lytic replication results in neuronal cell death as described above. (2,3) During latency the genome circularizes and enters a heavily chromatinated state where no infectious virus is produced and the majority of viral gene expression is silenced. Latency associated transcripts (LAT), mRNA genes, are the only transcripts found in latent neurons (6). Expression of LATs is not absolutely required for maintenance of latency. Reactivation triggers the virus to be transported in the opposite direction, antrograde, and re-infection occurs at the initial site of infection. HSV and the Immune SystemThe immune response to HSV-1 includes both innate and adaptive immune responses. Innate immunity is the first line of defense including natural killer (NK) cells, macrophages, dendritic cells, and various cytokines and complement proteins. Initial response involves secreted proteins, such as defensins and complement proteins. Complement proteins bind HSV antigens resulting in the cleavage of complement molecules. This, followed by the formation of the membrane attack complex, destroys the virus. HSV gC blocks the complement cascade, counteracting the effects of complement.The adaptive immune response is triggered with B cell memory enhanced in response to the virus. An antiviral state is induced by infected epithelial cells and resident interferon producing cells (IPCs), secreting interferon ? and ? , priming the surrounding cells for apoptosis. Tumor necrosis factors ? (TNF-? ) is also produced by IPCs and acts as an autocrine signal stimulating differentiation of ICPs to dendritic cells. They can travel to the lymph nodes to stimulate CD4+ T cells to produce IFN-? and interleukin 10 (IL-10). After infection and replication, HSV-1 destroys infected cells and travels to sensory neurons.Polymorphonuclear leukocytes, macrophages, NK and TCR+ T cells infiltrate the TG, control the infection and prevent the spread of the virus to rear by cells, including the brain. The adaptive immune response is driven by the innate immune response. Antigen presenting cells migrate from the site of infection to the regional lymph node to present CD4+ and CD8+ T cells and B cells. Deficient complement cascades leads to less vigorous memory response to HSV-1. Antibodies against gD and the gH-gL complex are found to protect against HSV-1 and are observed as cross reactive to other strains of HSV.Macrophages engulf viral proteins and cell particles from lysed cells and also secrete cytokines favoring the T helper (Th) cell CD4+ response. CD8+ cytoxic T lymphocytes (CTL) are produced and they react with epitopes displayed on infected cells, which are then targeted for apoptosis. See figure 2. The IE protein ICP 27 contains potent CTL epitopes. The efficacy of gB to induce a CTL response suggests gB is the immunodominant antigen of HSV-1. (2) Beneficial Modifications of Genes Associated with Herpes Simplex Virus type 1 and Relative As sociated DiseasesOccasionally the immune system is unable to prevent HSV-1 from spreading to surrounding structures such as the eye. Ocular HSV-1 infection is termed herpetic keratitis, tissue destruction of the eye, and is currently treated with trifluridine or valacyclovir to inhibit HSV-1 DNA polymerase and terminate synthesis of the sugar backbone of viral DNA. The current antiviral compounds require phosphorylation by the infected cell, meaning the antiviral activity cannot take place until the infection has progressed to the point where specific viral thymidine kinase is synthesized.A new idea involves helicase-primase inhibitors acting to prevent the unwinding of the double-stranded DNA and the initiation of the new strand synthesis necessary for viral production. Kleymann et al. found a compound, BAY 57-1293, more potent and more effective than valacyclovir and unassociated with systemic toxicity to initiate the described mechanism. (7) A similar study explored the lesion as sociated with the tissue destruction of the cornea, specifically angiogenesis of stromal keratits (SK).The fibroblast growth factor 2 (FGF-2), a molecule known to stimulate cell growth to contribute to wound healing, was targeted to observe the antiviral activity via its effect on HSV-1 cell entry. FGF-2 inhibits HSV-1 from binding to heparin sulfate, thus hindering entrance into the host cell. Results of this study suggest severity and clinical SK could be significantly diminished by daily treatment of lesions with FGF-2 protein, due to accelerated epithelial wound healing. (8) Similarly, HSV-1 can surpass the immune response and travel to the brain. HSV-1 encephalitis is the most devastating consequence of HSV and the most ommon cause of fetal encephalitis. Early growth response 1 (Erg-1) is a zinc finger transcription factor expressed in neural tissue, and is induced during stress. It regulates growth, apoptosis, angiogenesis and development. Erg-1 is known to regulate several vi ral genes, including LATs, and is inducible by viral proteins. Erg-1 increases viral replication in infected cells and mortality in infected mice. Knockout of Erg-1 expression was shown to reduce the mortality by decreasing the viral loads to tissues in a study conducted by Shis-Heng Chen et al. 9) It has been demonstrated HSV-1 can induce increased activity of central norepinephrine or serotonin neurons, by activating the cell bodies located in the brain stem, following encephalitis. Increased brain stem activity of these neurotransmitters can impair glucocorticoids (GC) negative feedback receptors, activating cytokines IL-1 and TNF? , reducing the binding capacity of said GC receptors. Impaired control of the GC negative feedback regulation upon the hypothalamo-pituitary adrenal axis has been suggested as an important aspect in major depression. (10)Thrombin is a result of the generation of sequential proteolytic enzymes activating circular precursor enzymes and cofactors for bloo d clotting. HSV-1, HSV-2 and cytomegalovirus have been shown to avoid cellular control of coagulation initiation through the constitutive expression of procoagulant phospholipids and tissue factor. This allows the unregulated generation of thrombin because tissue factor can bind ciruculating factor VIIa, forming a cofactor-enzyme complex directly on the virus. ââ¬ËTenaseââ¬â¢ activity has been credited to HSV-1 encoded gC, which accelerates the FVIIa-dependent activation of FX.FXa associates with its cofactor V to convert prothrombin to thrombin. Assembly of FX and FV leading to thrombin generation has been demonstrated on the virus surface. Herpes virus genomic material has been associated with atherosclerosis plaque, thrombosis and atherosclerosis due to the unregulated production of thrombin. (11) It is well known NK cells aid in the fight against HSV-1 infection. Severe herpetic infections have been seen in NK -deficient patients, as well as early infiltrations of herpetic lesions by NK cells. This due to damage of HLA class 1 expression by HSV-1 and the lysis of HSV-1 infected targets by NK cells.E. Estefania et al. presented a study suggesting clinical symptoms of HSV-1 infection being more likely to happen among humans expressing the NK cell receptors KIR2DL2 and KIR2DS2. The genes encoding the receptors appear to increase the risk of recurrent infection, where the lack of the receptors is shown to protect from the disease. (1) Conclusion HSV-1 can cause severe recurrent disease in humans and establish lifelong infection in their hosts. Several antiviral approaches have been considered to counteract the effects of HSV-1 throughout the body yet no vaccine, to cure the infection from its host, has been accepted.Acyclovir, and its ester derivative valacyclovir, as well as penciclovir and its prodrug famciclovir, are the latest approved antiviral medications to battle HSV-1 infection. Several other strategies are currently under investigation such as potential therapeutic vaccines, cidofovir, and aqueous extracts in Africa. Past attempts of vaccines have utilized viral vectors, DNA vaccination, recombinant bacteria, cytokines to manipulate the immune response, novel adjuvants, innovative delivery systems and different routes of inoculation. Most of which have been successful in lab mice but none have been approved for human use.Therapeutic vaccines target symptomatic individuals, using DNA vaccines encoding various cytokines used to intentionally bias the immune system toward Th1 or Th2 responses. Different boosts with different cytokine adjuvants may be used to induce proper immune response. (2) Extracts from the eastern cape of Africa, Aloe ferox and Withania somnifera, confirmed morphological changes indicative of cytopathic effects that retard the replication and spread of HSV-1. (12) Furthermore, a hematopoietic stem cell transplant recipient developed mucosal HSV-1 infection, and while under acyclovir treatment, later show ed resistance to the antiviral.After developing hemorrhagic cystitis due to polyomavirus BK, cidofovir was prescribed and the patient profited from the broad spectrum anti-DNA virus activity with the disappearance of HSV-1 lesions. (13) In conclusion, as described above the mechanisms by which HSV-1 hijacks and hides out in its host, have been studied to great detail and are routinely manipulated. The particularly complex structure, as well as detailed means by which each gene in the large genome is activated and carries out its genes products, intrigue many scientists which continue to investigate and attempt a formidable vaccine against the virus.Studies among mice have proven effective, although HSV-1 is a very host specific infection, thus making trials of acceptable anitvirals and vaccines extremely difficult. The only slightly acceptable element of HSV-1 infection is, in rare cases where no reoccurrences is shown, and moreover there are many instances of asymptomatic carriers. Devastating incidence such as transferring HSV-1 to a neonate during delivery and schizophrenics showing decreased prefrontal grey matter due to HSV-1, are just a pinch of the terrifying effects of this virus, remaining in host TG until a stressful situation comes along. 14,15) Herpes Simplex Virus type 1 Genome (Figure 1) 00 Herpes Simplex Virus Type 1 Infection (Figure 2) Works Cited 1. )Estefania, E, et al. ââ¬Å"Influence of KIR gene diversity on the course of HSV-1 infection: resistance to the disease is associated with the absence of KIR2DL2 and KIR2DS2. â⬠Tissue Antigens 70. 1 (July 2007): 34-41.
