Herpes, from the ancient Greek meaning to creep or crawl, is the name of a family of viruses of which herpes simplex virus 1 and herpes simplex virus 2 (HSV-1 and HSV-2) are the most serious human pathogens. HSV-1 is normally associated with orofacial infections and encephalitis, whereas HSV-2 usually causes genital infections and can be transmitted from infected mothers to neonates. Both viruses establish latent infections in sensory neurons and, upon reactivation, cause lesions at or near point of entry into the body.
While HSV-1 and HSV-2 are different viruses, under a microscope, HSV-1 and 2 are virtually identical, sharing approximately 50% of their DNA and are treated similarly.
HSV-1 and HSV-2 contain a large double-stranded DNA molecule. HSV is gram negative, consists of 162 capsomers and replication takes place within the nuclei of eukaryotic cells. The HSV virion has four parts: an electrondense core containing viral DNA; an icosapentahedral capsid; a tegument-an amorphous layer of proteins that surround the capsid; and an envelope. HSV-1 and HSV-2 encode at least 84 different polypeptides. Each protein does many things, hence HSV genes can encode several hundred different functions. To initiate infection, HSV attaches to at least three different classes of cell-surface receptor and fuses its envelope with the plasma membrane. The capsid, minus its envelope, is transported to the nuclear pore, through which it releases viral DNA into the nucleus. HSV replicates by three rounds of transcription that yield: alpha (immediate early) proteins that mainly regulate viral replication; beta (early) proteins that synthesise and package DNA; and gamma (late) proteins, most of which are virion proteins. Of the 84 known polypeptides, at least 47 are not needed for viral replication in cultured cells. These 47 genes are not completely dispensable. Some complement cellular genes that are not expressed in terminally differentiated cells; others alter cellular metabolism to ensure high virus yields. Mutant viruses lacking these genes cannot survive in nature.
The symptoms of genital herpes vary widely form person to person. Some people have severe symptoms (such as many painfu...

...Unlike the culture method, this test does not require growing the virus but rather seeks to identify herpes by the presence of antigens, fragments of the virus that are know to stimulate the immune response.
Herpes cannot be cured. Once someone is infected with either virus, it cannot be cleared from the human body. Genital herpes is usually treated with antiviral drugs such as Acyclovir (Zovirax), Famciclovir (Famvir), and Valacyclovir (Valtrex) to help keep the virus in an inactive state and prevent most outbreaks but again does not cure a person from the virus.
During an active herpes episode people should follow a few key steps to speed healing and avoid spreading the infection to other places on the body or to other people:
· Keep the infected area clean and dry to prevent other infections from developing
· Try to avoid touching the sores
· Wash you hands after contact with the sores
· Avoid sexual contact from the time the first symptom is felt until the sores are completely healed, that is, the scab has fallen off and new skin has formed where the sore was.
Most people in the U.S. learn STDs in their health class in high school. Syphilis is a sexually transmitted disease (STD) that causes sores over private parts or all over the body in a later stage. Syphilis is caused by a bacteria called spirochete. The spirochete cannot survive outside the body. The only way to get the disease is by intimate contact, but catching it is rare. Having more than one partner could increase the chances to catch the disease. The spirochete enters in a break in your skin genitals area or mouth. Once in your body, about three weeks it becomes a sore or have multiple sores. The sore looks like a crater on the surface of the skin. In the first stage it can be treated easily with antibiotics or penicillin. The second stage the syphilis spreads to the rest of the body. It is visible in your hand and soles on your feet. It can cause cardio-vascular disease, mental problems, paralysis, blindness and tumors. Syphilis has links to HIV/AIDS. It also attacks your nervous system. After infection it takes 21 to develop any symptoms for other people it takes from 10 to ninety days. It acts like no other disease known. The last stage is the deadliest if ignored, by the person. The damage obtained by syphilis is irreversible. By practicing safe sex (condoms), or having one sex partner can prevent these

There is no vaccine for HIV, but there are some drugs that can extend their lives. Some of the treatments that are offered are very expensive and are not available to all people with HIV. Also, these treatments do not work for about 20% of people who have tried them. Some of the best ways to avoid contracting HIV is to abstain from sexual intercourse and from sharing needles if you do drugs. Do not share personal items that may be contaminated with blood.
Her evidence and use of pictures brought a sense of an image to this story’s timeline that she created for the reader. She successfully went through the Twentieth Century in complete order, and it gave a sense of organization to Schwartz’s writing, which ultimately led to an easier read for the audience. She makes her case by using factual information, primary sources, secondary sources, and images as sources to show the impact of tourism. She defines tourism in Cuba as an idiosyncratic industry that left influences throughout the history of this country. She in addition makes her case by describing the social change of tourist and the idea of tourism throughout the important decades for the

Pathogens are a type of microorganism that spreads viral and bacterial diseases. These diseases when present in human blood and body fluids are known as blood borne pathogens, and can spread from one person to another. (Worcester polytechnic institute) The most serious types of blood borne diseases are the hepatitis B virus (HBV) and hepatitis C virus (HCV), which can cause liver damage; and HIV (human immunodeficiency virus), which is responsible for causing AIDS (acquired immune deficiency syndrome). The blood borne pathogens can be spread when the blood or body fluids (semen, vaginal fluid, breast milk, and amniotic fluid) of an infected individual comes into contact with mucous membranes or an open sore or cut on the skin of another person. Mucus membranes are located in the eyes, nose, mouth, and other areas as well. ("Bloodborne pathogens: MedlinePlus Medical Encyclopedia") Two of the most common ways that pathogens are transmitted is through the exchange of fluids during sexual intercourse or by sharing infected IV needles.

Amazon is the biggest online store in the world; since its creation in 1995, Amazon has adopted improvements throughout its processes changing considerately. This reports describes the changes adopted by Amazon. In addition, this report generates a diagnosis of each step and makes a deep analysis of the decision makings by amazon based on three specific topic; 1) when Amazon managed inventory internally; 2) when Amazon decided to outsource inventory management and lastly when amazon decided to sell products of competing retailers on its site.
The purpose of this report is to understand the evolution of the inventory management of Amazon and how it has affected the company’s growth. This case study is both a practice case and a problem solving case, so the first section of this report focuses on the practices used by Amazon in the 4 stages and then in the second section we will solve the problem regarding their product returns problem and provide recommendations.
Sexually Transmitted Diseases Sexually Transmitted Diseases STDs, a.k.a venereal diseases, infectious diseases passed from one person to another during sexual contact. STDs are the most common infections known. More than 12 million people in the United States, including 3 million teenagers, are infected with STDs every year. The United States has the highest STD rate in the world about one in ten Americans will contract an STD during his or her lifetime. People who do not know they are infected risk infecting their sexual partners and, in some cases, their unborn children. If left untreated, these diseases may cause pain or may destroy a woman's ability to have children. Some STDs can be cured with a single dose of antibiotics, but AIDS cannot be cured. Those most at risk for contracting STDs are people who have unprotected sex—without using a condom, people who have multiple partners, and people whose sex partners are drug users who share needles. Static’s show that Americans between the ages of 16 and 24 are most likely of catching STDs than older adults, because younger people usually have multiple sexual partners than an older person in a long-term relationship. Teenagers may be embarrassed to tell their sexual partners they are infected Teenagers may also be embarrassed or unable to seek medical attention for STDs. This means that they only more likely to pass the disease to other young people and have a greater risk of suffering the long-term consequences of untreated STDs. STDs are transmitted by infectious bacteria, viruses, parasites, fungi, and single-celled organisms called protozoa that live in warm, moist parts of the body, like the genital area, mouth, and throat. Most STDs are spread while having sex, but oral sex can also spread disease. Some STDs are passed from a mother to her child while pregnant, when the disease enters the baby's bloodstream, during childbirth as the baby passes through the birth canal, or after birth, when the baby drinks infected breast milk. AIDS can be transmitted by blood contact such as open wounds, between people who share infected needles or received through an injection of infected blood. Some people believe that STDs can be transmitted through shaking hands or other casual contact, or through contact with inanimate objects such as clothing or toilet seats, but they can’t. Chlamydeous, is from trachoma is bacterium, is the most commonly transmitted STD in the United States.
