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.

Study confirms overuse of blood transfusions during surgery

Citing the lack of clear guidelines for ordering blood transfusions during surgery, Johns Hopkins researchers say a new study confirms there is still wide variation in the use of transfusions and frequent use of transfused blood in patients who don't need it.

Oregano ingredient could treat prostate cancer

Oregano, the common pizza and pasta seasoning herb, has long been known to possess a variety of beneficial health effects, but a new study by researchers at Long Island University (LIU) indicates that an ingredient of this spice could potentially be used to treat prostate cancer, the second leading cause of cancer death in American men.

Vitamin D deficiency associated with increase in lung transplant rejection, infections

Vitamin D deficiency is associated with an increase in lung transplant rejection and infections, according to research conducted at Loyola University Health System.

Researchers discover how dendritic cells exchange information to amplify immune response

Using a new fluorescent biosensor they developed, researchers at Carnegie Mellon University have discovered how a key set of immune cells exchange information during their coordinated assault on invading pathogens.

Immunosignatures can yield reliable and highly stable diagnostic results

Identifying diseases at an early, presymptomatic stage may offer the best chance for establishing proper treatment and improving patient outcomes. A new technique known as immunosignaturing harnesses the human immune system as an early warning sentry-one acutely sensitive to changes in the body that may be harbingers of illness.

Researchers describe novel mechanism of HIV-1 spread by dendritic cells

A new understanding of the initial interactions of human immunodeficiency virus type 1 (HIV-1) and dendritic cells is described by Boston University School of Medicine (BUSM) researchers in a study currently featured in the Proceedings of the National Academy of Sciences.

Cancer therapy with common cold virus

Common viruses have become the latest weapon against cancer. There is the case of the eight-year-old African boy diagnosed with Burkitt's lymphoma at a Ugandan health clinic. He was exposed to the measles virus and in the next few weeks his tumour regressed completely and he entered remission. But only relatively recently have scientists clinically examined the interaction between viruses and cancers in the growing area of oncolytic virotherapy.

HDAC6 protein may provide novel target for stress-linked disorders

A cellular protein called HDAC6, newly characterized as a gatekeeper of steroid biology in the brain, may provide a novel target for treating and preventing stress-linked disorders, such as depression and post-traumatic stress disorder (PTSD), according to research from the Perelman School of Medicine at the University of Pennsylvania.

Study explains association between alcohol consumption and breast cancer

A research team this week will present findings that they say may finally explain the link between alcohol consumption and breast cancer.

Beta cells from genetically modified pigs can effectively restore pancreas function

Transplantation of a whole pancreas or isolated insulin-producing beta cells are the only therapy to cure type 1 diabetes. However, the shortage of organ donors limits this approach to only few patients. LMU researchers have now shown that beta cells from genetically modified pigs can effectively restore pancreas function and can protect porcine beta cells from immune rejection in animal models.

BAMC/SAMMC researcher develops microemulsion vaccine carrier

A researcher at the Brooke Army Medical Center (BAMC)/San Antonio Military Medical Center (SAMMC) will present findings this week on a new potential vaccine carrier that he hopes will extend the shelf life of and aid in the stockpiling of critical vaccines.
