Certain mix of bacteria in vagina may play role in causing VVA in postmenopausal women

The mix of bacteria in the vagina changes as women go through menopause. And a certain mix is typical after menopause in women who have vulvovaginal atrophy (VVA), a common cause of vaginal dryness and sexual pain, finds a team at Johns Hopkins and the University of Maryland.

Genetically modified bacterial treatment approach reduces or eliminates sleeping sickness

A tag team of two bacteria, one of them genetically modified, has a good chance to reduce or even eliminate the deadly disease African trypanosomiasis, or sleeping sickness, researchers at Oregon State University conclude in a recent mathematical modeling study.

Discovery paves way for development of new medicines to combat herpes infections

Researchers at Lund University in Sweden and Carnegie Mellon University have for the first time managed to measure the internal pressure that enables the herpes virus to infect cells in the human body. The discovery paves the way for the development of new medicines to combat viral infections. The results indicate good chances to stop herpes infections in the future.

Researchers develop new type of E. coli that kills bacteria responsible for hard-to-treat infections

The notorious bacteria E. coli is best known for making people sick, but scientists have reprogrammed the microbe - which also comes in harmless varieties - to make it seek out and fight other disease-causing pathogens.

Specialized cells play major role in inflammation that underlies Crohn's disease in small intestine

Scientists have discovered that Crohn's disease, the inflammatory bowel disorder, can originate from specialised intestinal cell type called Paneth cells. As such, they propose that small intestinal Crohn's disease might be a specific disorder of this cell type, providing a possible new target for treatments.

NCI explores how erectile dysfunction drugs work to prevent colon cancer

Erectile dysfunction drugs may be able to help prevent or even treat colon cancer, researchers say.

Queen's research to investigate how superbug affects cystic fibrosis patients

Queen's University Belfast is to lead a £139,000 study into the way cystic fibrosis sufferers are affected by a superbug that destroys lung function.

NIH awards 10 new grants to support genomics research in Africa

The National Institutes of Health has awarded 10 new grants totaling up to $17 million over the next four years to support genomics research in Africa, as part of the Human Heredity and Health in Africa (H3Africa) program

Exposure to farming environment may reduce symptoms of hypersensitivities, allergies

Adults who move to farming areas where they experience a wider range of environmental exposures than in cities may reduce the symptoms of their hypersensitivities and allergies considerably. This is the result of new research from Aarhus University.

Research findings show how flawed transport gene contributes to autism

Researchers say it's clear that some cases of autism are hereditary, but have struggled to draw direct links between the condition and particular genes. Now a team at the Johns Hopkins University School of Medicine, Tel Aviv University and Technion-Israel Institute of Technology has devised a process for connecting a suspect gene to its function in autism.

Shortage of zinc may contribute to diseases like Alzheimer's and Parkinson's

Scientists at the University of Wisconsin-Madison have made a discovery that, if replicated in humans, suggests a shortage of zinc may contribute to diseases like Alzheimer's and Parkinson's, which have been linked to defective proteins clumping together in the brain.

MD Anderson-developed aerosol triggers innate immunity to squelch infections

Research on an aerosol that jump-starts a rapid immune response to stifle viral respiratory infections before they can provoke asthma attacks has earned major funding from the National Institutes of Health.

Intestinal mucus potentially improves life of people suffering from inflammatory bowel disease

Researchers at Institut Hospital del Mar d'Investigacions M-diques (IMIM) in Barcelona, in collaboration with the Icahn School of Medicine at Mount Sinai in New York and other U.S. Institutions, have found that intestinal mucus not only acts as a physical barrier against commensal bacteria and dietary antigens, but also prevents the onset of inflammatory reactions against these agents.

TSRI scientists discover process by which special immune cells in skin help heal wounds

Scientists at The Scripps Research Institute (TSRI) have discovered an important process by which special immune cells in the skin help heal wounds. They found that these skin-resident immune cells function as "first responders" to skin injuries in part by producing the molecule known as interleukin-17A (IL-17A), which wards off infection and promotes wound healing.

Scientists report advancement in smartphone-based imaging to detect viruses in remote locations

Scientists are reporting an advance in smartphone-based imaging that could help physicians in far-flung and resource-limited locations monitor how well treatments for infections are working by detecting, for the first time, individual viruses. Their study on the light-weight device, which converts the phone into a powerful mini-microscope, appears in the journal ACS Nano.

New animal model may help study immune responses to H. pylori infection

Researchers at the Virginia Bioinformatics Institute at Virginia Tech have developed a new large animal model to study how the immune system interacts with the stomach bacterium Helicobacter pylori, the leading cause of peptic ulcer disease.

MIT engineers develop nanoparticles that deliver cancer vaccines to lungs

Many viruses and bacteria infect humans through mucosal surfaces, such as those in the lungs, gastrointestinal tract and reproductive tract. To help fight these pathogens, scientists are working on vaccines that can establish a front line of defense at mucosal surfaces.

Study on tempol impacted gut bacteria may lead to new treatments for obesity

A drug that appears to target specific intestinal bacteria in the guts of mice may create a chain reaction that could eventually lead to new treatments for obesity and diabetes in humans, according to a team of researchers.

Johns Hopkins receives $7.3M contract to reduce ventilator-associated pneumonia

The Johns Hopkins Armstrong Institute for Patient Safety and Quality has been awarded a three-year, $7.3 million contract from the Agency for Healthcare Research & Quality to bring its proven checklist for reducing ventilator-associated pneumonia — the most lethal of all hospital-acquired infections — to hospitals nationwide.

Microbial clock: New tool to determine time of death

An intriguing study led by the University of Colorado Boulder may provide a powerful new tool in the quiver of forensic scientists attempting to determine the time of death in cases involving human corpses: a microbial clock.
