Chemical from Medicinal Plants May Be Used to Fight HIV

Like other kinds of cells, immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division. As a result, the cell changes in many ways, and its disease fighting ability is compromised.
But a new UCLA AIDS Institute study has found that a chemical from the Astragalus root, frequently used in Chinese herbal therapy, can prevent or slow this progressive telomere shortening, which could make it a key weapon in the fight against HIV

Doctors have long suspected that people with herpes are more likely to catch HIV. So they thought that by treating herpes, they could also cut a person's HIV risk. But a new study that tested this strategy found the assumption may have been wrong.
Global Analysis of Host-Pathogen Interactions that Regulate Early-Stage HIV-1 Replication

Human Immunodeficiency Viruses (HIV-1 and HIV-2) rely upon host-encoded proteins to facilitate their replication. Here, we combined genome-wide siRNA analyses with interrogation of human interactome databases to assemble a host-pathogen biochemical network containing 213 confirmed host cellular factors and eleven HIV-1-encoded proteins. Protein complexes that regulate ubiquitin conjugation, proteolysis, DNA-damage response, and RNA splicing were identified as important modulators of early-stage HIV-1 infection
Antibody fights AIDS-like disease in monkeys

An antibody treatment has rejuvenated the immune systems of macaques infected with a virus called SIV, allowing the monkeys to fend off the symptoms of an AIDS-like disease for months. SIV is studied as a model for HIV infection in humans, and the therapy could be tested in clinical trials of HIV-infected patients as soon as next year, pending approval by regulators.
One fourth of American teenage girls have at least one STD.

We've been talking about Gardasil and Cerverix a lot recently. Sure, lots of parents are reluctant to vaccinate their children before they become teenagers, but a nationwide study reveals that 50% of black teenagers and 20% of white teenagers have at least one STD. The specific age ranges are fourteen to nineteen. And what is the most common infection out there? Shocker of shockers, it's HPV

Measels is on the rise in the U.S. There have been sixty-four cases this year alone. Only one of these patients can be shown to have had the vaccine. There have been no fatalities so far.
Sixteen of these children are from families who declined vaccination for religious or other resasons, including fear of autism

According to this article, we know that the virus toll in China continues rise. EV71is highly contagious, causing fever, blisters in the mouth and a rash on the hands and feet. From this report, it is said that the outbreak emerged in Fuyang city in March, but was only reported in mid-April. The reason why there was a delay in the reporting at the provincial level was that they didn’t know what the causes for these different cases were.

Bacteria that can cause serious heart disease in humans are being spread by rat fleas, sparking concern that the infections could become a bigger problem in humans. Research published in the December issue of the Journal of Medical Microbiology suggests that brown rats, the biggest and most common rats in Europe, may now be carrying the bacteria.
Since the early 1990s, more than 20 species of Bartonella bacteria have been discovered

The U.S. Food and Drug Administration (FDA) has granted SELZENTRY™ (maraviroc) full (traditional) approval for use in treatment-experienced adults with CCR5-tropic HIV-1 in combination with other antiretrovirals. SELZENTRY was originally granted accelerated conditional approval in August 2007 based on 24-week data from pivotal Phase 3 studies. SELZENTRY now becomes the latest fully approved treatment for HIV.
“New, effective and well-tolerated treatment options are critical for treatment-experienced persons living with HIV infection,” said W
New Way Men Can Transmit HIV to Women

Researchers at Northwestern University have discovered a critical new way a man can transmit the HIV virus to a woman.
Scientists had long believed that the normal lining of the female vaginal tract was an effective barrier to invasion of the HIV virus during sexual intercourse. They thought the large HIV virus couldn't penetrate the tissue.
But new research from Northwestern University's Feinberg School of Medicine has shown for the first time that the HIV virus does indeed penetrate a woman's normal, healthy genital tissue to a depth were it can gain access to its immune cell targets.
Pyruvate Kinase Deficiency and Malaria

Malaria that is caused by Plasmodium falciparum is a significant global health problem. Genetic characteristics of the host influence the severity of disease and the ultimate outcome of infection, and there is evidence of coevolution of the plasmodium parasite with its host. In humans, pyruvate kinase deficiency is the second most common erythrocyte enzyme disorder. Here, they show that pyruvate kinase deficiency provides protection against infection and replication of P
Alzheimer's Risk Factor Also Aids HIV

The defective lipid carrier apolipoprotein E4 (apoE4) has accumulated a nasty record. Not only are people who have the gene for apoE4 famously predisposed to Alzheimer's disease, but the same risk factor can also worsen several nervous system disorders and promote cardiovascular disease. A study out this week suggests that apoE4 also hastens the death of people infected with HIV, possibly by allowing the virus easy entry into cells.
The pen is mightier than the infection!
Darkfrog submitted, created time 2 months 2 weeks (well.blogs.nytimes.com)
The pen is mightier than the lawsuit ...at least when it comes to avoiding surgical mistakes. A pen can be used to mark the part of the patient's body meant for surgery. It can be done when the patient is wide awake and able to participate and, if necessary, able to say, "No, not that leg, THAT ONE!!" The phenomenon is called wrong-sided surgery and the solution, it seems, is a laundry pen.
You'd be surprised how much that helps
Antibiotics before infections save lives

Giving antibiotics to patients in intensive care units as a precaution saves lives, according to a major Dutch study published Wednesday.

One Australian newspaper, referring to a study about an antibiotic-resistant bacterial infection affecting homosexual men in San Francisco and other American cities.
Maybe it's a big bomb in the field of "gay" infection.
