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

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
China virus toll continues rise

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.
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!

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

Maybe it's a big bomb in the field of "gay" infection.

People share their homes, their food and more with their pets, but one thing you probably never thought you could share with your animals is a drug-resistant staph infection.

Before long, the outbreak of enterovirus 71, a type of hand, foot and mouth disease that children are susceptible to in Fuyang city has been paid close attention to, which is another headache for the communist government as it prepares for the Beijing Olympics already tarnished by an uprising among Tibetans and an international torch relay disrupted by protests. And China's Health Ministry ordered heightened efforts to stem the spread of infectious diseases Saturday following an outbreak of a virus

Fuyang City of east China's Anhui Province recently saw a severe outbreak of EV-71. Meanwhile, nearly 800 other cases were reported in other parts of Anhui, though only 24 are reported dead. And now China orders heightened efforts to stop this deadly virus. The ministry has sent expert teams to Anhui to lead treatment of the disease and prevent its spread. We believe that this disaster will be overcome quickly due to the efforts of our nation's people.

The interaction between the twin pandemics of HIV and TB could soon become a "threat to global health security," particularly with the emergence of almost untreatable strains of TB, experts at a United Nations forum have said.
HIV in the U.S. hits American blacks extra hard
Darkfrog submitted, created time 2 months 1 week (www.nytimes.com)
The CDC has released a report on the way HIV spreads in the United States. Again, American blacks are at disproportionately high risk. While caucasian gay and bisexual men tend to get infected int heir thirties and forties, black gay and bisexual men tend to get infected in their teens and twenties.
The writeup does not say whether they adjusted for socioeconomic factors, but they do assert that the infected blacks were no more likely to be drug users or to engage in risky sexual behaviors than their counterparts in other races
