Study: Soap And Water Work Best In Ridding Hands Of Disease Viruses

..."Hand hygiene agents have been shown to reduce the incidence of health-care associated infections, and a variety of hand hygiene agents are now available with different active ingredients and application methods. "Our study showed that the anti-microbial hand washing agents were significantly more effective i...

Potential Cure for Lymphoma in HIV patients

...ividuals remains challenging, due to both the high incidence ofrefractory disease and the high risk of treatment-relatedcomplications. The ability of high dose chemotherapy as demonstrated inthis pilot study to effectively treat even refractory disease is highlyencouraging and certainly warrants further study....

New studies suggest airborne SARS transmission is possible

...f the first case seemed to be strongly linked with incidence of infection-two-thirds of patients in the same bay and half of patients in an adjacent bay were infected with SARS, while only 18 percent of patients in distant bays were infected. The Hong Kong researchers, led by Ignatius T.S. Yu, MBBS, MPH, of t...

How an AIDS-Related Cancer Unleashes Inflammation

...gh new HIV treatments have drastically reduced the incidence of Kaposi's sarcoma in developed countries, it remains a health threat in many developing countries. Now, researchers have discovered one way that Kaposi's sarcoma ?a cancer-like viral disease traditionally associated with AIDS ?triggers severe infla...

Genetically modified rice in China benefits farmers' health, study finds

...sticide related illnesses Because there is a high incidence of pesticide-related illness in households of developing countries, including China, the researchers were interested in tracking the health effects of insect-resistant genetically modified rice. They asked farm family members if they experienced any ...

HIV vaccine trial breaks ground for future research

...gh vaccine antibody response is related to a lower incidence of HIV infection. Citing the possible slight vaccine efficacy for non-white and high-risk participants of the trial, they urged that future vaccines be studied in a wide range of racial, ethnic, and diverse risk-level groups. They concluded that the ...

Insight into natural cholesterol control suggests novel cholesterol-lowering therapy

As a result, cells take up more cholesterol from the bloodstream, lowering its concentration there. However, inhibition of reductase function by statins also li...

Harmful chemicals may reprogram gene response to estrogen

...tic form of estrogen linked to vaginal cancer, the incidence of uterine tumors rises to almost 100 percent. By comparison, slightly more than half of the unexposed animals, those having only the genetic defect, developed the uterine tumors. DES is a drug that was prescribed for women from 1938 to 1971 to prev...

Insight into DNA's 'weakest links' may yield clues to cancer biology

Earlier work by other researchers had shown that mammalian chromosomes break at particular sites under certain types of stress or upon exposure to particular drugs, he said. Evidence has suggested that chromosomes break when D...

Study reveals dramatic difference between breast cancers in US and Africa

...mewhere in between, with a slightly lower lifetime incidence of breast cancer than Caucasians but earlier onset and worse prognosis. African American women under the age of 35 have a 50 percent greater risk of developing breast cancer than Caucasians. This risk levels off by around age 50 and African Americans...

Agilent Technologies new genome analysis technology set to accelerate Australia fight against mesothelioma

...bestos in the mid-1900s, Australia has the highest incidence of mesothelioma in the world. Rates of the disease have tripled in the past 20 years and are expected to peak about 2010. Diagnosis of this type of cancer is difficult, and patients are often not identified until the condition is quite advanced. Agi...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists
