Diffused ultraviolet radiation penetrates beach umbrellas

A team of researchers from the University of Valencia (UV) has proven that 34% of ultraviolet radiation filters through under beach umbrellas. According to what is published in the journal Photochemistry and Photobiology, umbrellas intercept the full direct flow that comes from the Sun, but not the diffused radiation that penetrates through from the sides.

Researchers identify a substance that protects farm children from allergies, allergic asthma

Researchers from Bochum have isolated the substance in cowshed dust that possibly protects farm children from developing allergies and allergic asthma, namely the plant sugar molecule arabinogalactan. If high concentrations thereof are inhaled during the first year of life it inhibits the immune system from excessive defense reactions.

Abbott presents 48-week PROGRESS study results at 28th International AIDS Conference

Abbott today presented 48-week findings comparing an HIV regimen of its protease inhibitor (PI), Kaletra® (lopinavir/ritonavir), and Merck's integrase inhibitor, Isentress® (raltegravir), to a traditional HIV regimen of Kaletra and the nucleotide/nucleoside reverse transcriptase inhibitors (NRTIs) in Truvada® (tenofovir and emtricitabine) in antiretroviral-naive adult patients. Efficacy data were collected over the first 48 weeks of the 96-week PROGRESS (PROtease/InteGRasE Simplification Study) study.

FIT Biotech to present results of FIT-06 Phase II clinical trial at XVIII International AIDS 2010 Conference

FIT Biotech, a privately held biotechnology company developing novel, proprietary immunotherapies for HIV/AIDS and other viral diseases, announced results today from a Phase II clinical trial. The company's immunomodulator FIT-06 showed unprecedented long-term reductions in viral load (approximately 0.5 log) and statistically significant CD4 cell count increases in HIV-infected, previously untreated patients. The effect lasted longer than two years in the absence of any anti-retroviral therapy.

New mechanism that drives development of B-lymphocytes in bone marrow discovered

Scientists from the Department of Molecular Immunology, Institute of Biology III, Faculty of Biology and the Centre for Biological Signalling Studies, BIOSS have discovered a new mechanism that drives the development of B-lymphocytes in our bone marrow. B-lymphocytes are an important part of our immune system. Upon their activation they produce the antibodies protecting us from infections.

Also in Global Health News: WHO reacts to Amnesty's N. Korea report; Universal flu vaccine; Malaria-resistant mosquitoes

The WHO is questioning the validity of the findings of a recent Amnesty International report which highlighted the dire needs of North Korea's health system, "contradict[ing] the rosier picture given by WHO chief Margaret Chan after her April trip there," the Associated Press reports. Although WHO spokesman Paul Garwood "insisted he wasn't criticizing Amnesty's work … he said Thursday's report was anecdotal, with stories dating back to 2001," which "[h]e contrasted … with WHO's science-based approach" (7/16).

Impact of circadian dysregulation on mental, physical health

Circadian (daily) rhythms are found in all functions - e.g. performance, mood, endocrine rhythms, behaviour, sleep timing. The biological clocks that control circadian rhythms are based on a genetic programme of interacting molecules in cells throughout the body, coordinated by a ´master clock´ in the brain and synchronised by external cues, mainly light.

Study compares denture stomatitis genes with whole transcriptome for salivary biomarker analysis

The goal of the study was to compare whole-transcriptome, mucosal gene expression in Candida albicans (a parasitic fungus that can infect the mouth) associated chronic denture stomatitis to that of healthy oral mucosa and perform proteomic analyses of potential salivary biomarkers. Denture stomatitis is a condition in which the mucosa underneath a denture becomes inflamed and sometimes painful.
