Stress may increase cervical cancer risk

A woman’s daily stress can reduce her ability to fight off a common sexually transmitted disease and increase her risk of developing the cancer it can cause. – A woman’s daily stress can reduce her ability to fight off a common sexually transmitted disease and increase her risk of developing the cancer it can cause, according to a new study. No such association is seen, however, between past major life events, such as divorce or job loss, and the body’s response to the infection.

HIV persists in gut despite long term HIV therapy

Even with effective anti-HIV therapies, doctors still have not been able to eradicate the virus from infected individuals who are receiving such treatments, largely because of the persistence of HIV in hideouts known as viral reservoirs. – HIV virus is not usually eradicated from infected individuals even after long term HIV therapy because of the persistence of HIV in hideouts known as viral reservoirs. One important reservoir is the gut, where HIV causes much of its damage due to the large number of HIV target cells that reside there.

DNA sequencing found virus killing transplant recipients in Australia

DNA sequencing establishes high throughput genetic sequencing as powerful tool for pathogen discovery; technology enables improvements in screening for transplant safety. – In the first application of high throughput DNA sequencing technology to investigate an infectious disease outbreak, link the discovery of a new arenavirus to the deaths of three transplant recipients who received organs from a single donor in Victoria, Australia in April 2007.

New hope for hepatitis C sufferers

Adelaide scientists will lead a $2 million five-year project to develop new vaccines and explore better treatment options for hepatitis C sufferers. – University of Adelaide virologists Dr Michael Beard and Dr Karla Helbig will work with colleagues from the University of NSW to develop new strategies to treat and prevent hepatitis C, which infects more than 170 million people around the world.

Breastfeeding safer for infants of HIV mothers with Nevirapine

First solid evidence that viral transmission through breast milk can be prevented by a drug Nevirapine HIV drug. – An antiretroviral drug already in widespread use in the developing world to prevent the transmission of HIV from infected mothers to their newborns during childbirth has also been found to substantially cut the risk of subsequent HIV transmission during breast-feeding.

Prodesse’s ProFlu+ Test for Respiratory Viruses receives FDA clearance

Prodesse’s ProFlu+ Test for Respiratory Viruses receives FDA clearance for Marketing Real-Time Test, detects four viruses, including influenza; results available in about 3 hours. – Prodesse, Inc., the leader in multiplex real-time PCR for infectious disease, announced that it received clearance from the U.S. Food and Drug Administration (FDA) to market its ProFlu+? Assay.

Intelence, etravirine HIV Drug approved in US

The U.S. Food and Drug Administration approved etravirine tablets for the treatment of HIV infection in adults who have failed treatment with other antiretrovirals. Etravirine is a non-nucleoside reverse transcriptase inhibitor (NNRTI) that helps to block an enzyme which HIV needs to multiply. – US FDA approved Tibotec Therapeutics’ Intelence, etravirine tablets for the treatment of HIV infection, to be used in combination with other anti-HIV medications, in adults who have failed treatment with other antiretrovirals.

Climate change a rising risk to health

The effects of climate change on various aspects including natural resources, agricultural activity, population health, and social and economic development. – Climate change could have far-reaching negative impacts on the health of rural Australians, reported in a study co-authored by a Charles Sturt University (CSU) scientist. The report published in the Australian Journal of Rural Health.

AIDS drugs may prevent vaginal transmission of HIV

There are 33 million people infected with HIV. This study is a highly significant breakthrough because it offers proof-of-principle that pre-exposure prophylaxis with currently available anti-retroviral drugs can potentially prevent vaginal HIV transmission, empowering women throughout the world to protect themselves from this deadly disease. – Prescription drugs now used to treat human immunodeficiency virus infection in adults may prevent the vaginal transmission of HIV, researchers at UT Southwestern Medical Center have found.

273 human proteins required for HIV propagation

Using a technique called RNA interference to screen thousands of genes, researchers identified 273 human proteins required for HIV propagation. The vast majority had not been connected to the virus by previous studies. – Current drugs attack HIV itself, leaving patients vulnerable to counterattack by the rapidly mutating virus, which often evolves resistance. But the human proteins exploited by HIV represent potential therapeutic targets that could avoid this problem. The challenge will be to develop drugs that inhibit HIV by interacting with these human proteins without hurting our cells.
