HIV Replication 3D Animation it is a very excellent animation which explains the hiv replication very clearly. For free download of this video please visit my webpage http://rufusrajadurai.wetpaint.com/page/Download And other 3D animation videos visit http://rufusrajadurai.wetpaint.com/page/3D+Medical+Animation+Library Regards, Dr.Rufus The Lyrics of this video is here Targeting HIV replication The replication of HIV 1 is a multi-stage process. Each step is crucial to successful replication and is therefore a potential target of antiretroviral drugs. Step one is the infection of a suitable host-cell, such as a CD4-positive T-lymphocyte. Entry of HIV into the cell requires the presence of certain receptors on the cell surface, CD4 -- receptors and co-receptors such as CCR5 or CXCR4. These receptors interact with protein-complexes, which are embedded in the viral envelope. These complexes are composed of two glycoproteins: an extracellular gp 120 and a transmembrane gp 41 When HIV approaches the target cell gp120 binds to the CD4-receptors. This process is termed attachment. It promotes further binding to a co-receptor. Co-receptor binding results in a conformational change in gp120. This allows gp41 to unfold and insert its hydrophobic terminus into the cell membrane. Gp 41 then folds back on itself. This draws the virus towards the cell and facilitates the fusion of their membranes. The viral nucleocapsid enters the host cell and breaks open releasing two viral RNA-strands and 3 essential replication enzymes: Integrase, Protease and Reverse Transcriptase. Reverse Transcriptase begins the reverse transcription of viral RNA. It has two catalytic domains: The Ribonuclease-H active site And the polymerase active site Here single stranded viral RNA is transcribed into an RNA-DNA double helix. Ribonuclease- H breaks down the RNA. The polymerase then completes the remaining DNA-strand to form a DNA -- double helix. Now Integrase goes into action. It cleaves a dinucleotide from each 3-prime end of the DNA creating two sticky ends. Integrase then transfers the DNA into the cell nucleus and facilitates its integration into the host cell genome. The host cell genome now contains the genetic information of HIV. Activation of the cell induces transcription of proviral DNA into messenger RNA. The viral messenger RNA migrates into the cytoplasm where building blocks for a new virus are synthesised. Some of them have to be processed by the viral protease. Protease cleaves longer proteins into smaller core proteins. This step is crucial to create an infectious virus. Two viral RNA-strands and the replication enzymes then come together and core proteins assemble around them forming the capsid. This immature particle leaves the cell acquiring a new envelope of host and viral proteins. The virus matures and becomes ready to infect other cells. HIV replicates billions of times per day destroying the hosts` immune cells and eventually causing disease progression. Drugs which interfere with the key steps of viral replication can stop this fatal process. Entry into the host cell can be blocked by fusion inhibitors for example. Inhibition of reverse transcriptase by nucleoside inhibitors or by non-nucleoside Reverse Transcriptase- inhibitors is part of standard antiretroviral regimens. The action of Integrase can be blocked. Protease inhibitors are also part of standard antiretroviral therapy. Each blocked step in viral replication is a step towards better control of HIV disease.

Did I Just Contract HIV? Symptoms of Primary HIV Infection It's sometimes possible to recognize when you've recently contracted HIV from signs and symptoms such as fever, rash, or swollen lymph nodes. This video will teach you how to recognize signs and symptoms of primary HIV infection that are experienced by between 40 and 90% of individuals after they are first infected with HIV. Primary HIV infection occurs during the first few weeks or months after a person first becomes infected with HIV. Symptoms include rash and/or fevers, possibly in combination with one or more of the following symptoms: malaise (which is a general feeling of weakness, discomfort, and fatigue), loss of appetite, weight loss, a sore throat, sores in the mouth, joint or muscle pain, swollen lymph nodes, diarrhea, fatigue, night sweats, nausea and vomiting, headache, or genital sores. The symptoms usually last from seven to ten days, and rarely more than two weeks. There is an incubation period of a few days to a few weeks between when the person was exposed to HIV and when the symptoms begin. If you have any of these symptoms and think there's even the slightest chance you might have been exposed to HIV, such as through recent sexual activity or sharing a needle, even with someone who you believe is HIV negative, you should see a doctor and ask to be tested for HIV. When you go to the doctor with any of these symptoms, it's very important to mention any risk factors you may have for HIV so they could test you. If you have ever had unprotected sex, even once, have used injection drugs, or think you might be experiencing primary HIV infection, make sure to tell your doctor.

The Top Ten Myths About HIV/AIDS Becky Kuhn, M.D., co-founder of Global Lifeworks, debunks the following 10 myths about HIV: HIV doesn't cause AIDS; because of ARV medications, we no longer need to be concerned about HIV/AIDS; if you have HIV and are sexually active, you no longer need to practice safer sex; you can't contract HIV through oral sex; you can't get HIV from one sexual encounter; a woman cannot spread HIV to another woman by having sex with her; if you are HIV positive but your viral load is undetectable, you cannot spread HIV; AIDS can be spread by kissing, hugging, or shaking hands; if you have HIV, you can cure it by having sex with a virgin; every individual with HIV will eventually develop AIDS.

BAYER SPREADS AIDS HIV SEX Hemopheliac medicine children Bayer Corporation put live H.I.V. Virus in their hemopheliac medicine for children- and shipped it all over the world. This is complete and utter TERRORISM and all those involved are guilty according to experts I have been reading on google. I'm pretty sure there are terrorism laws against this type of mass murder. I feel so bad for all the thousands of families and children who were infected due to Bayer Corporation. This is the epitome of bad-business, and un-ethical, careless behavior. Why would they do this to us? They have a moral responsibility to protect us. We are the source of thier wealth. We are thier customers. Please spread this around. Maybe somebody can help fix the problem? Maybe Bayer can step up and find a CURE?? Tags: stds hiv bayer corporation sex aids government reverend pastorJeremiah A.

Introduction to HIV/AIDS: What You Need to Know Becky Kuhn, M.D., co-founder of Global Lifeworks, covers critical basic information about HIV and AIDS. HIV is a virus that causes the disease AIDS, which can be fatal. There are treatments but no cure. HIV is spread by contact between body fluids (blood, semen, vaginal fluids, and breast milk) and mucous membranes (eyes, nose, mouth, and genitals). It is spread by sexual contact, injection drugs users sharing needles, from mother to child during childbirth or nursing, and (early on during the epidemic) by receiving blood transfusions. You can reduce your risk by abstaining from sex before marriage, being faithful to a single partner and using a condom and/or dental dam if you are sexually active, and by never injecting drugs or by never sharing needles if you do. It can take up to six months after exposure to HIV for a person to test HIV positive; even before they test HIV postive, the infected person can spread the disease to others. A doctor can prescribe antiretroviral (ARV) drugs to prevent HIV from progressing to clinical AIDS. It is critical to take every ARV dose on schedule to avoid developing a resistant strain of HIV. If a person is HIV positive, they still need to practice safer sex to avoid spreading HIV to others and to avoid contracting a different, resistant strain of HIV.

Merck Vaccine Chief Brings HIV/AIDS to America This stunning censored interview conducted by medical historian Edward Shorter for WGBH public television (Boston) and Blackwell Science was cut from The Health Century due to its huge liability--the admission that Merck drug company vaccines have traditionally been injecting cancer viruses (SV40 and others) in people worldwide. This segment of In Lies We Trust: The CIA, Hollywood & Bioterrorism, produced and freely contributed by consumer protector and public health expert, Dr. Leonard Horowitz, features the world's leading vaccine expert, Dr. Maurice Hilleman, who explains why Merck's vaccines have spread AIDS, leukemia, and other horrific plagues worldwide.

HIV: The Greatest Medical Hoax of our Time. Pt 1 FROM HIV TEST-KIT INSERTS: • "At present there is no recognized standard for establishing the presence or absence of HIV-1 antibody in human blood." (Abbott Lab HIV Test - ElA) • "The risk of an asymptomatic person with a repeatedly reactive serum developing AIDS or an AIDS-related condition is not known." (Genetic Systems HIV Test - Peptide EIA) • "The AMPLICOR HIV-1 (PCR "Viral Load") MONITOR test is not intended to be used as a screening test for HIV or as a diagnostic test to confirm the presence of HIV infection" (Roche, Amplicor HIV Test Kit). • "Do not use this kit as the sole basis of diagnosis of HIV-1 infection." (Epitope, Inc. HIV Test - Western Blot) • "Clinical studies continue to clarify and refine the interpretation and medical significance of the presence of antibodies to HIV." (Abbott Laboratories HIV Test - ElA) Wikipedia defines HIV as: Human immunodeficiency virus (HIV) is a retrovirus that causes acquired immunodeficiency syndrome (AIDS) This statement is not only false it is not backed by any scientific proof. HIV does not even classify as a retrovirus by definition since it has never been isolated and it has never been proven that can be spread by any means. Further, in the 100,000+ studies done on AIDS to date there has NEVER been proof that HIV leads to AIDS or that they are even related. In fact, by definition of a retrovirus, HIV may not even exist at all! Yes, you are reading this correctly. The test, we are told, that will tell whether someone is HIV positive and therefore develop AIDS does not even test for the virus itself. It tests for components of the virus antibodies and proteins that we are told are specific only to HIV. This is also FALSE. The first Western Blot test by Robert Gallo tested some 75% of the population as being HIV positive. All he did was lower the sensitivity to target the gay population. He also added hydrocortisone to the list which is found in people who are under stress. There are a number of proteins that are misclassified and all of which can be found in any healthy person in different levels depending on a number of factors. Also, we are told that a T-cell count below 200 is a determining factor for HIV. If you were to take a cross section of the population who do not have any risk for HIV and test their T-cell counts you will find that it ranges from 180-1500. And that is in normal healthy individuals, therefore 200 is at the low end of normal. If HIV were a virus, an infectious disease as we are told it is, it would have spread through the rest of the population certainly by now. Why hasn't it? Because what we are told about HIV and AIDS is a LIE! DEMAND ANSWERS AND QUESTION THE SOURCES! It is unfortunate that we live in a culture in which corporate capitalism is the law of the land. The pharmaceutical industry is calling the shots and they know that they are sitting on an absolute gold mine by spreading disinformation about this and other so, called diseases. Remember, a patient cured, is a customer lost. Follow the money and question those who profit from from it. Robert Gallo is a fraud. His Western Blot Test makes a mockery out of science. His work was NEVER peer reviewed before it was released, and it was later determined that he stole his construct of HIV from French researchers. He has to share the profits from the sales of the so called HIV test as a result. Educate yourself, and be aware of charlatans like Robert Gallow. HIV=AIDS is a LIE. HIV has never been isolated. Robert Gallo is a liar and a fraud. His test for HIV is pure medical malpractice. He should be imprisoned for spreading disinformation and be held accountable for promoting the hysteria he has created over the HIV=AIDS hypothesis. The HIV=AIDS hypothesis is a LIE. Further, out of the 100,000+ studies and reports on AIDS, no one has EVER achieved Retroviral Isolation of HIV. Tags: hiv aids awareness hoax medical malpractice retroviral isolation |

Bayer Exposed ( HIV Contaminated Vaccine ) http://www.whale.to/vaccines.html [Video] Bayer Sells AIDS-Infected Drug Banned in U.S. in Europe, Asia - Unearthed documents show that the drug company Bayer sold millions of dollars worth of an injectable blood-clotting medicine -- Factor VIII concentrate, intended for hemophiliacs -- to Asian, Latin American, and some European countries in the mid-1980s, although they knew that it was tainted with AIDS. Bayer knew about the fact that the drug was tainted and told the FDA to keep things under wraps while they made a profit off of a drug that infected its patients. If these allegations are true, then both Bayer and the FDA are at fault for this catastrophe. FDA regulators helped to keep the continued sales hidden, asking the company that the problem be ''quietly solved without alerting the Congress, the medical community and the public,'' according to the minutes of a 1985 meeting octomedia Vaccine Information and Awareness sites: http://thinktwice.com/ http://www.vaclib.org/ Tags: octomedia contaminated vaccine Bayer Exposed HIV AIDS LIES Infected Drug profit KILLER KILLED |
