UNC scientists isolate protein that could play role in asthmatics

Researchers at the UNC School of Medicine believe they have isolated a protein that, when missing or depleted, can cause airway constriction, production of mucus, chest tightness, and difficulty breathing for the 334 million people worldwide who suffer from asthma.

Scientists evaluate rapid test that detects colistin resistance gene in bacterial isolates

Colistin is used as the "last-resort antibiotic" for dreaded multidrug-resistant pathogens, especially in hospitals. However, gut bacteria that have become insensitive to colistin now exist -- owing to the mobile resistance gene mcr-1. In early 2016, bacteria carrying this resistance gene were detected in Germany for the first time.

Researcher creates molecular diagnostic system that can quickly identify dangerous bacteria

A Michigan State University researcher has developed a faster way to detect the bacteria causing patients to become sick, giving physicians a better chance at saving their lives.

Study paves way for therapies against myeloid-derived suppressor cells that collude with cancer

Some cells excite the immune system. Others soothe it. Myeloid-derived suppressor cells (MDSCs) are one type of soothing cell, and previous work shows that cancer may specifically boost production of MDSCs as a way to tamp down immune response against tumors. At least that's how it works in mice.

Using common pain relievers during acute respiratory infection linked to increased heart attack risk

Widely used pain relievers may increase the risk of a heart attack when used during a cold or flu-like illness, according to a new study published in the Journal of Infectious Diseases.

Oral dose of phage cocktail prevents infection and cholera-like symptoms in animal model

Oral administration of a cocktail of three viruses, all of which specifically kill cholera bacteria, prevents infection and cholera-like symptoms in animal model experiments, report scientists from Tufts University School of Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts in Nature Communications on Feb. 1.

SLU scientists receive $416,000 NIH grant to advance research on hepatitis B cure

With a $416,000 grant from the National Institutes of Health (NIH), SLU scientists will continue work to cure hepatitis B, building on significant findings published in two recent papers.

Johns Hopkins researchers uncover mechanism in chikungunya virus that controls disease severity

Researchers led by the Johns Hopkins Bloomberg School of Public Health have identified a mechanism by which the chikungunya virus infects healthy cells and controls how severe the disease it causes will be, a mechanism they believe can be found in a number of other related viruses for which there are no treatments or licensed vaccines.

Mini-gut model provides clues to enterovirus infections in infants

Using immature stem cells to create a miniature model of the gut in the laboratory, researchers at Washington University School of Medicine in St. Louis and the University of Pittsburgh have determined how infection-causing enteroviruses enter the intestine.

UAB researchers find how gut fails to prevent HIV-1 infection

The barrier between the gut and the bloodstream is severely damaged in the first few weeks of infection by HIV-1 virus.

Penn researchers shed new light on potential causes of premature birth

Depending on the specific type, bacteria in a woman's vagina and cervix may increase the risk of premature birth or protect against it, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

UCLA-led researchers identify potential TB drug regimen that may cut treatment time up to 75%

Taking a new approach toward tuberculosis therapy, a UCLA-led research team has devised a potential drug regimen that could cut the treatment time by up to 75 percent, while simultaneously reducing the risk that patients could develop drug-resistant TB.

New treatment for C.diff infections reduces recurrences by 40%, study finds

A new treatment for Clostridium difficile (C.diff) infections reduces recurrent infections by nearly 40%, a large study has found.

Scientists decipher mechanism of CA-MRSA that plays role in development of skin infections

Staphylococcus aureus is one of the most feared, multi-resistant pathogens. The bacterium often causes life-threatening infections, particularly in people with a weakened immune system.

Researchers reveal central role of new key players in meiosis

Where would we be without meiosis and recombination? For a start, none of us sexually reproducing organisms would be here, because that's how sperm and eggs are made. And when meiosis doesn't work properly, it can lead to infertility, miscarriage, birth defects and developmental disorders.

Cervicovaginal microbial communities in pregnant woman may be key to preventing preterm birth

A team of researchers that has confirmed the presence of bacteria in a woman's vagina and cervix may either increase the risk of premature birth or have a protective effect against it, has won the March of Dimes Award for Best Abstract on Prematurity at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting. The findings will be presented Thursday, January 26, at 1:15 p.m. PST at Caesars Palace Augustus Ballroom in Las Vegas.

Bruker is to be key International Phenome Centre Network corporate partner for NMR Technologies and SOPs

The International Phenome Centre Network (IPCN), founded by Imperial College London and more than a dozen international partners in Australia, Canada, China, Japan, Singapore, Taiwan, the US, and the UK (www.phenomenetwork.org), was launched officially this week at the 2016 World Innovation Summit for Health (WISH) conference in Doha, Qatar. This global network is a critical link between leading research centers across the world and will support research into some of today’s most pressing global health challenges.

Researchers identify new principle for how epigenetic changes can occur

In a new study, researchers at Uppsala University have found evidence of a new principle for how epigenetic changes can occur. The principle is based on an enzyme, tryptase, that has epigenetic effects that cause cells to proliferate in an uncontrolled manner.
