Topical treatment shown to inhibit HIV and herpes simplex virus infection

... CVL obtained at baseline. The effects were highly statistically significant (p "An inflammatory responses could potentially increase susceptibility to HIV and limit any protective effect of microbicides." said Betsy Herold, M.D., Professor of Medicine and Chief of Pediatric Infectious Disease at Mount Sinai and ...

Neuronal 'traffic jam' marks early Alzheimer's disease

...stein. "We found in the early cases a very strong, statistically meaningful swelling in the neurons." The researchers tested whether they could enhance the pathology they observed in the mice and humans by reducing the levels of a key transport protein, kinesin-1, the cell's principal molecular motor for transpor...

Newly discovered virus linked to childhood lung disorders and Kawasaki disease

... methods to do so were unavailable at thetime. The statistically strong association with Kawasaki disease,however, was "quite surprising." Noting that previous attempts to linkKawasaki disease to bacteria or other viruses had failed and thusjustified healthy skepticism about the present findings, Dr. McIntoshpoint...

HIV vaccine trial breaks ground for future research

...ubgroups of the study population, a higher, though statistically insignificant, vaccine efficacy was found in the high-risk and the non-white groups. The authors suggested two plausible explanations, one for each group. Those with high-risk behavior may have been exposed frequently to HIV and a primed immune respo...

HIV-1 spread through six transmission lines in the UK

...lth Protection Agency and the University of Oxford statistically analysed the epidemic history of the HIV-1 subtype B strain from sampled gene sequence data. Molecular data on HIV-1 has become increasingly available since the introduction of routine HIV-1 gene sequencing for drug resistance. Scientists used this d...

Bevacizumab Combined With Chemotherapy Improves Progression-Free Survival for Patients With Advanced Breast Cancer

... paclitaxel chemotherapy alone. This difference is statistically significant. “This study is the first to find a benefit of anti-angiogenic therapy in patients with breast cancer and represents a major advance in the treatment of patients with metastatic disease," said Study Chair Kathy D. Miller, M.D., of the Ind...

Antiretroviral Therapy May Prevent HIV Transmission From Breastfeeding Mothers To Infants

...of the women not taking therapy. This represents a statistically significant difference. However, there was no such difference for HIV-1 DNA, which some studies suggest also contributes to mother-to-child transmission. One possible explanation for this lack of association between antiretroviral therapy and HIV DN...

Circulating stem cells play small role in lung repair

...ocytes was less than 1 percent. They also found a statistically significant relationship between the number of Y chromosome-containing pneumocytes and the incidence of acute cellular rejection in the tissue, suggesting that stem cell repopulation might be stimulated by greater degrees of injury to the lung. The ...

Study casts doubt on 'Snowball Earth' theory

...heet ice during the pre-Cambrian glaciation. It is statistically unlikely but possible, Olcott said, that the drill core found one of the tiny "refugia" for marine life whose existence is allowed under the "Snowball Earth" hypothesis. But, she said, "finding the one anomalous spot would be quite unlikely," adding...

"Our methods can of course be adapted for comparing other food plants," says Fiehn. The analyses were financed by...

Prenatal exposure to famine increases risk of schizophrenia

David St. Clair, M.D., Ph.D., of Shanghai Jiao Tong University, Shanghai, China, and colleagues conducted a study to test the hypothesis that prenatal exposure to famine would increase the rate of schizophrenia in adult life by examinin...

NJIT study shows nanoparticles could damage plant life

"We suppose that the surface characteristics of the nanoparticles played an important role in slowing the growth of the roots," said Watts. "The smaller the particle, the larger is the total amount of surface area per unit weight. So ...
