Poverty linked to HIV infection among heterosexuals living in inner-city neighborhoods

In a groundbreaking study published last year, scientists reported that effective treatment with HIV medications not only restores health and prolongs life in many HIV-infected patients, but also curtails transmission to sexual partners up to ninety-seven percent. However, a new study by UCSF scientists shows that lack of basic living needs severely undercuts these advances in impoverished men.

UIC researcher to explore causes of myasthenia gravis

A University of Illinois at Chicago researcher is the recipient of a $240,000 research grant to further explore the causes of myasthenia gravis, a neurologic disease affecting muscles.

A melanoma cloaking protein

Johns Hopkins and Yale scientists have found that melanoma cells use a cloaking protein to hide from immune cells poised to attack the cancer. Nearly 40 percent of their sampling of melanoma tissues contained the B7-H1 protein, also called PD-L1, and scientists say it could be used as a target for new therapies.

Allergies may provide benefit by keeping away noxious environmental toxins

Yale researchers suggested Wednesday that allergies may be an outgrowth of the protective mechanism of the body to protect itself from noxious substances in the environment.

Helpful roles of rank, toxic substances

Usually, we think of mold, feces, nitric oxide, hydrogen sulfide and rat poison as rank, toxic or both. But scientists funded by the National Institutes of Health are learning more about the helpful roles these substances can play.

First-ever study to evaluate effects of interaction between metamphetamines and Ibudilast

John W. Tsuang, M.D., principal investigator at the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed), in conjunction with Steven J. Shoptaw, Ph.D., from the UCLA Department of Family Medicine, is spearheading a Phase I clinical safety trial that for the first time examines the effects of Ibudilast when administered with metamphetamine (MA), an addictive stimulant that is closely related to amphetamine.

Physical activity reduces oxidative stress in people with SCT

Sickle cell disease (SCD), an inherited condition that causes red blood cells to sometimes deform into a crescent shape, affects an estimated 100,000 Americans, typically those of African descent. However, far more have sickle cell trait (SCT), caused when individuals carry just a single copy of the disease-causing mutation in their genes.

Study sheds new light on common food poisoning bug

BBSRC-funded researchers at Cambridge University have shed new light on a common food poisoning bug. Using real-time video microscopy, coupled with mathematical modelling, they have changed our assumptions about Salmonella and how it infects human cells.

Pig mucus effective at blocking viruses associated with cervical and oral cancer

Scientists are reporting that the mucus lining the stomachs of pigs could be a long-sought, abundant source of "mucins" being considered for use as broad-spectrum anti-viral agents to supplement baby formula and for use in personal hygiene and other consumer products to protect against a range of viral infections. Their study appears in ACS' journal Biomacromolecules.

Study examines role of NLRP3 inflammasome in ventilator-induced lung injury

Mechanical ventilation is often lifesaving, but can also initiate or aggravate lung injury. A new study in the May issue of Anesthesiology examined the role of one particular receptor in the inflammatory pathway, the NLRP3 inflammasome, and whether it impacts ventilator-induced lung injury.

Link between obesity and RA in women

Obesity and the painful autoimmune disorder rheumatoid arthritis are each becoming more common, raising a logical question: Could one have something to do with the other? For women, it appears there is a link, Mayo Clinic researchers say.

Body’s own DNA can cause inflammation in the heart

DNA from the heart's own cells plays a role in heart failure by mistakenly activating the body's immune system, according to a study by British and Japanese researchers, co-funded by the British Heart Foundation.

Kids who are abused or bullied may age faster

The study finds that violence-related stress in children affects telomeres - special DNA sequences found at the tips of chromosomes. Telomeres, which prevent DNA from unravelling, get shorter each time cells divide, which limits the number of times cells can divide. Shorter telomeres have been linked to poorer survival and chronic diseases. Previous research has shown that smoking, obesity, mental-health disorders and stress may accelerate the process of telomere loss. This suggests that telomere length may reflect a person's biological age as well as their chronological age.

Lophius Biosciences completes prospective multicenter clinical validation study for T-Track CMV/EBV tests

Lophius Biosciences, a leading developer of novel T-cell based diagnostic testing systems, today announces the successful completion of a prospective multicenter clinical validation study for its T-Track CMV/EBV tests.

Clinical and Translational Science Institute-Children's National awards pilot grant to GW researchers

GW researchers in the School of Medicine, Jeffrey M. Bethony, Ph.D., Associate Professor of Microbiology, Immunology, and Tropical Medicine and David Diemert, M.D., FRCP(C), Associate Research Professor of Microbiology, Immunology, and Tropical Medicine and Director of Clinical Trials for the Sabin Vaccine Institute's Product Development Partnership (PDP), have been awarded a Pilot Grant from the Clinical and Translational Science Institute-Children's National.

Researchers examine whether fast foods impact body's reaction to stress in married couples

Today's busy families often rely on fast food and take-out to keep everyone fed and on schedule. Researchers at The Ohio State University Wexner Medical Center want to know whether those types of food, which are often high in saturated fat, impact the body's reaction to stress.

MMP-10 gene plays a dual role in lung cancer

A single gene that promotes initial development of the most common form of lung cancer and its lethal metastases has been identified by researchers at Mayo Clinic in Florida.
