Researchers unravel dual role of tumor necrosis factor in TB

Tumor necrosis factor - normally an infection-fighting substance produced by the body- can actually heighten susceptibility to tuberculosis if its levels are too high.

Researchers identify defective gene responsible for isolated congenital asplenia

The spleen is rarely noticed, until it is missing. In children born without this organ, that doesn't happen until they become sick with life-threatening bacterial infections.

New initiative launched to create more effective ED therapies based on brain imaging studies

Current treatments for anorexia and bulimia nervosa, which afflict an estimated 10 to 24 million Americans, are often limited and ineffective.

Scientists demonstrate feasibility of using already-approved drugs against pathogens

In the most extensive screen of its kind, Texas Biomed scientists in San Antonio have demonstrated the feasibility of repurposing already-approved drugs for use against highly pathogenic bacteria and viruses.

Tiny proteins prevent bacterial gene transcription

In the search for new antibiotics, researchers are taking an unusual approach: They are developing peptides, short chains of protein building blocks that effectively inhibit a key enzyme of bacterial metabolism.

Researchers use metagenomics to reconstruct genome sequence of Shiga-toxigenic Escherichia coli

Researchers have been able to reconstruct the genome sequence of an outbreak strain of Shiga-toxigenic Escherichia coli using metagenomics (the direct sequencing of DNA extracted from microbiologically complex samples), according to a study in the April 10 issue of JAMA, a Genomics theme issue.

More research needed to measure impact of co-infections on hospital admission

A study at Rhode Island Hospital has found that despite complications, patients co-infected with the pandemic 2009-2010 influenza A H1N1 (pH1N1) and a second respiratory virus were not associated with worse outcomes or admission to the hospital's intensive care unit.

UCSB researchers examine role played by Rhs proteins in bacterial intercellular competition

There's an epic battle taking place that's not on the national radar: intercellular competition. While it's not an Olympic event, new research from UC Santa Barbara demonstrates that this microscopic rivalry can be just as fierce as humans going for the gold.

Transient electronics relieve pain, fight infection and dissolve harmlessly

Scientists today described key advances toward practical uses of a new genre of tiny, biocompatible electronic devices that could be implanted into the body to relieve pain or battle infection for a specific period of time, and then dissolve harmlessly.

Scientists succeed to control cells' behavior using light

Scientists at Washington University School of Medicine in St. Louis have shown they can coax cells to move toward a beam of light. The feat is a first step toward manipulating cells to control insulin secretion or heart rate using light.

National Jewish Health researchers unravel mystery of adjuvants

Aluminum salts, or alum, have been injected into billions of people as an adjuvant to make vaccines more effective.

HYFFI project examines positive effects of seaweed fibre on bacterial in human gut

Seaweeds are not only tasty, but they are a source of nutrients that could be beneficial for health and wellbeing. And like terrestrial plants, seaweeds also contain significant portions of fibre that reach the colon undigested. But does seaweed fibre have similar positive effects on bacterial in the human gut? That's the question that the HYFFI project, funded by the EU, is trying to solve.

Nobel Prize recipient describes on innate immunity at Annual Drosophila Research Conference

A young scientist's astute observation - that grasshoppers don't get sick - eventually led to profound insights into our own immunity.

6 Apr 2013

Researchers use single-cell genome sequencing approach to analyze microbe from biofilm in hospital

A team of researchers led by scientists from the J. Craig Venter Institute (JCVI) has published a study outlining the recovery and genomic analysis, using single-cell genomic techniques, of a periodontal pathogen, Porphyromonas gingivalis, from a hospital sink.

Study offers new possibilities for developing potent antibacterial drugs

A new study which was performed jointly at Ume- University and the University of Washington in Seattle, USA, discovered that bacteria can degrade the cell membrane of bacterial competitors with enzymes that do not harm their own membrane.

5 Apr 2013

Research findings provide insight into severe bacterial infectious diseases

UT Southwestern Medical Center researchers report that a pathogen annually blamed for an estimated 90 million cases of food-borne illness defeats a host's immune response by using a fat-snipping enzyme to cut off cellular communication.

UC San Francisco researchers outline cell-based therapeutics as a "third pillar” of medicine

Treating patients with cells may one day become as common as it is now to treat the sick with drugs made from engineered proteins, antibodies or smaller chemicals, according to UC San Francisco researchers.

Glowing bacteria inside squids use light and chemical signals to control circadian rhythms

Glowing bacteria inside squids use light and chemical signals to control circadian-like rhythms in the animals, according to a study to be published on April 2 in mBio-, the online open-access journal of the American Society for Microbiology.

4 Apr 2013

A new method to kill pathogenic bacteria

Engineering researchers at Rensselaer Polytechnic Institute have developed a new method to kill deadly pathogenic bacteria, including listeria, in food handling and packaging. This innovation represents an alternative to the use of antibiotics or chemical decontamination in food supply systems.

3 Apr 2013

New medical device detects biothreat agents

Researchers at Sandia National Laboratories are developing a medical instrument that will be able to quickly detect a suite of biothreat agents, including anthrax, ricin, botulinum, shiga and SEB toxin.
