Soft cheeses health threat to expectant mums

Cases of tuberculosis in New York City have been linked to queso fresco style cheeses which were imported from Mexico or consumed in Mexico, the cheese was found to be contaminated with Mycobacterium bovi which caused the infection.

Questions about validity of HOPE TOO vitamin E study

A study published in the March 16 issue of Journal of the American Medical Association (JAMA) suggesting that a "daily-dose" of vitamin E (400 international units) among high-risk (chronically ill) cardiovascular patient populations is associated with a greater risk of heart failure is being challenged by leading health researchers around the country who claim the study lacks the adequate research and controlled sampling audience to justify this conclusion.

Study reveals how brain's immune system fights viral encephalitis

The findings, published as the cover study in the latest issue of Virology, show that proteins in neurons fight the virus at multiple stages - by preventing the formation of viral RNA and proteins, and blocking the virus' release, which could infect other cells in the brain.

Cancer survival comes at its own price

Patients who hear the dreaded words "you have cancer" invariably look forward to the day the doctor tells them "you're cured." But University of Florida researchers say survival often comes at its own price -- the mind may need mending even after the body heals.

Drug-resistant bacteria on uncooked poultry products varies by commercial brand

The presence of drug-resistant, pathogenic bacteria on uncooked poultry products varies by commercial brand and is likely related to antibiotic use in production, according to researchers at the Johns Hopkins Bloomberg School of Public Health.

Risky surgery not always necessary to treat cervical disease

Revolutionary advancements in the treatment options for diseases associated with human papillomavirus (HPV) now include nonsurgical options such as chemoprevention and vaccines. A review of these methods is published in the latest issue of the International Journal of Gynecological Cancer.

Antiretroviral therapy may prevent some cancers in people with HIV

In people infected with human immunodeficiency virus (HIV), highly active antiretroviral therapy (HAART) may prevent most excess cases of Kaposi sarcoma and non-Hodgkin lymphoma, according to a new study in the March 16 issue of the Journal of the National Cancer Institute.

T’ai Chi has many benefits for frail older adults

It’s no longer an ancient Chinese secret. A University of Missouri-Columbia researcher is putting a new spin on an old exercise and the outcome has many benefits for frail older adults.

Link between a critical cancer pathway and an Epstein-Barr Virus (EBV) protein

Researchers at the University of Pennsylvania School of Medicine have identified a link between a critical cancer pathway and an Epstein-Barr Virus (EBV) protein known to be expressed in a number of EBV-associated cancers.

Timing is everything when it comes to killing prostate cancer cells

"The window of opportunity is narrow for vaccination, designed to reinvigorate the immune system's attack on cancer cells, and it occurs right after hormonal therapy begins to wipe out the tumor and immune cells outnumber cancerous ones," according to Charles Drake, M.D., Ph.D.

Gene identified that confers susceptibility to age-related macular degeneration

By combining the tools of high-throughput biology and statistical genetics, scientists at Rockefeller University, Yale University School of Public Health and the National Eye Institute have identified a gene that confers susceptibility to age-related macular degeneration (AMD), the most common cause of vision loss in the United Sates for those over 60.

Tumor-targeted immune cells cure prostate cancer without causing systemic immune suppression

In a major breakthrough in cancer gene therapy, a Northwestern University researcher has endowed immune cells with the ability to specifically target metastatic prostate cancer in mice without causing the toxic immune suppression that has been associated with earlier forms of cancer gene therapy.

Naturally occurring antifungal agent in saliva kills oral pathogen responsible for most HIV-related oral infections

Oral biologists at the University at Buffalo have shown for the first time how histatin, the naturally occurring antifungal agent in saliva, kills the oral pathogen Candida albicans, the fungus responsible for most HIV-related oral infections.

Discovery may provide a new target to treat sepsis

Part of the immune system's pro-inflammatory response to bacterial invasion is to increase nitric oxide levels with an enzyme called inducible nitric oxide synthase.

New way of looking at MicroRNA and how it controls gene expression

A group of scientists at The Scripps Research Institute is reporting a discovery that sheds light on an area of research fundamental to everything from the normal processes that govern the everyday life of human cells to the aberrant mechanisms that underlie many diseases, including cancer and septic shock.

China trials new HIV vaccine on humans

China which has 840,000 people with HIV, a conservative estimate say experts, will carry out the very first trials of a new virus on human guinea pigs.

Protopic and Elidel may cause cancer

Protopic and Elidel, two treatments for eczema approved in 2000 and 2001, have now been found to cause cancer in three different animal species.

Biologists discover why 10% of Europeans are safe from HIV infection

Scientists have known for some time that these individuals carry a genetic mutation (known as CCR5-Ä32) that prevents the virus from entering the cells of the immune system but have been unable to account for the high levels of the gene in Scandinavia and relatively low levels in areas bordering the Mediterranean.

Computerized order entry systems can increase the risk of medication errors

A new study suggests that computerized order entry systems which are implemented in part to reduce prescribing errors can actually increase the risk of medication errors in certain situations, according to a study in the current issue of JAMA.
