 | New Approach May Help Fight Tuberculosis It's a deadly disease that is hitting epidemic proportions.The World Health Organization says at least eight million new active cases of tuberculosis surface each year. One-third of the world's population is infected with TB and every second, another person is newly infected. The current TB vaccine is not effective in fighting TB in the lungs, but now, a VUMC research team has developed a new "very promising" approach to defeat the disease. Barb Cramer has the story. |
 | Top Secrets Revealed Episode 1 (1of3) During 2004, two UK television documentaries were produced which investigated the past activities of the UK Government's Biological Warfare facility at Porton Down, Wiltshire. The programmes revealed that scientists from Porton Down had used the UK as a vast outdoor laboratory during the Cold War. From 1950 to 1975, Porton scientists had clandestinely sprayed massive amounts of live bacteria (Serratia marcescens, E. coli MRE162 and Bacillus subtilis) and several tons of chemical compounds (such as Zinc Cadmium sulphide) over large parts of the UK. The first programme shows - how Royal Enfield workers in an underground factory at Westwood Quarry were repeatedly exposed to an opportunistic pathogen in the early 1950s; how members of the public travelling on a regular railway train on the Salisbury-Exeter line were sprayed with live bacteria by Porton scientists while travelling through a tunnel; how the city of Salisbury was 'attacked' during August of 1960 with large amounts of a cadmium compound: and how Porton sceintists conducted the large, and now infamous, series of experiments - known as the Lyme Bay Trials. The latter experiments exposed millions of UK residents to massive aerosols of live bacteria (E.coli and Bacillus subtilis) during the years 1963-1975. The huge bacterial clouds were sprayed from an Admiralty ship - ETV ICEWHALE - and were carried onshore by the wind and sampled by Porton scientists up to 50 miles inland. Athough this research was meant to be of a defensive nature, the official Porton film of these experiments stated: "Whilst these trials were designed for specific research purposes, they demonstrated, in a striking way, the feasibility of small-scale biological warfare. An appreciable dose of viable bacteria was achieved over an area greater than 1,000 square miles, by the release of only 120 gallons of suspension" |

 | 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 http://rufusrajadurai.wetpaint.com/ 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.
