HIV Replication 3D Medical Animation
 | It is a very excellent animation which explains the hiv replication very clearly. For free download of this video please visit my webpage 3dmed.wetpaint.com And other 3D animation videos visit 3dmed.wetpaint.com 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 ... |

Living with HIV: Chad's Journey
 | Chad's HIV diagnosis came along with some personal challenges. Rather than allow them to stand in his way, he faced those challenges head on and broke through to a renewed life of family and community support, activism and self-care. He is on a mission to make a difference in other people's lives. Chad volunteers with TPAN and Chicago House and Social Service Agency in Chicago. To find an AIDS service organization near you for support, visit www.AIDS.gov For more HIV diagnosis journeys, see Hattie, Andre and Daniel's videos at www.youtube.com All speakers in the video have been compensated by Janssen Therapeutics for their participation. ?Janssen Therapeutics, Division of Janssen Products, LP. 2011. |

Plight of Myanmar's HIV/AIDS patients exposed
 | As Myanmar opens up to the outside world, decades of neglect in areas such as HIV/AIDS treatment can no longer be hidden. Of the 120000 people living with HIV/AIDS in the country, only less than 30000 are believed to be receiving the medication they need. Around 20 thousand people die each year as the disease spreads throughout families. Al Jazeera's Wayne Hay reports from Yangon. |

HIV/AIDS vaccine developed at Western proceeding to human clinical trials
 | London, Ontario CANADA --The first and only preventative HIV vaccine based on a genetically modified killed whole virus has received approval by the United States Food and Drug Administration (FDA) to start human clinical trials. Developed by Dr. Chil-Yong Kang and his team at The University of Western Ontario, with the support of Sumagen Canada, the vaccine (SAV001) holds tremendous promise, having already proven to stimulate strong immune responses in preliminary toxicology tests with no adverse effects or safety risks. It is the only HIV vaccine currently under development in Canada, and one of only a few in the world. |
Did I Just Contract HIV? Signs and Symptoms of HIV
 | 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 ... |
