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.

Eating pistachios may help alter levels of beneficial bacteria in the gut

A preliminary 16-person study suggests that eating pistachios may help alter levels of potentially beneficial bacteria in the gut, a finding that holds promise for supporting digestive health. The research, presented as an abstract this week at the Experimental Biology conference, is the first study of pistachios and almonds and their modulating role on the gut microbiota composition.

Avocado oil protects against free radicals in mitochondria

Atmospheric oxygen facilitated the evolution and complexity of terrestrial organisms, including human beings, because it allowed nutrients to be used more efficiently by those organisms, which in turn were able to generate more energy. However, as we find out more about how oxygen molecules work inside the body, more attention is being paid to their not-so-good effects, and researchers are seeking ways to thwart them.

Gut microbiota plays a causal role in development of diabetes and NAFLD

Exciting new data presented today at the International Liver Congress 2012 shows the gut microbiota's causal role in the development of diabetes and non-alcoholic fatty liver disease (NAFLD), independent of obesity.

Scientists create reference guide for harmful germs in sand

On warm days, the beach seems an ideal destination for family rest and relaxation. Who hasn't built a sand castle or been buried up to the neck in sand? However, that family fun has a dark side -- sand can harbor illness-causing microbes. Unfortunately, there are no guidelines for sand quality at recreational sites.

New hypothesis may be a game changer in the evolution arena

A new hypothesis posed by a University of Tennessee, Knoxville, associate professor and colleagues could be a game changer in the evolution arena. The hypothesis suggests some species are surviving by discarding genes and depending on other species to play their hand.

Mere presence in a room can add 37 million bacteria

A person's mere presence in a room can add 37 million bacteria to the air every hour - material largely left behind by previous occupants and stirred up from the floor - according to new research by Yale University engineers.

Researcher joins nationwide effort to monitor resistance to antibiotics

Because infectious microorganisms are becoming increasingly resistant to antibiotics, a Wayne State University researcher has joined a nationwide effort to monitor that resistance while optimizing the use of existing drugs.

Identity of probiotics a key factor in determining safety, efficacy of popular ingredient

Regulators, manufacturers and academic researchers from around the world will convene for a two-day workshop on the scientific and regulatory challenges posed by the use of probiotic ingredients in food products. Discussions will focus on how public standards can assist in supporting transparency, consistency and competitiveness of ethical industry players as health claims surrounding probiotic products undergo increased scrutiny.

Vaccine to prevent Campylobacter in chickens can help reduce food-borne illness

A vaccine could be developed to prevent Campylobacter being carried in chickens. This approach could drastically cut the number of cases of food poisoning, saving the UK economy millions each year, says an American scientist presenting his work at the Society for General Microbiology's Spring Conference in Dublin.

Multiresistant bacteria withstand wastewater treatment processes

Large quantities of antibiotic-resistant bacteria enter the environment via municipal - and especially hospital - wastewater streams. Although wastewater treatment plants reduce the total number of bacteria, the most hazardous - multiresistant - strains appear to withstand or even to be promoted by treatment processes. This was demonstrated by Eawag researchers in a study carried out in Lake Geneva, near Lausanne.

UI receives three grants to hasten discovery of new TB therapeutics

Forty-five years. That's how long it's been since the last drug - rifampin - hit the market to treat tuberculosis, an infection that affects nearly one third of the world's population and causes 1.8 million deaths annually. The University of Illinois at Chicago College of Pharmacy has received three new federally-funded grants to hasten the discovery of new therapeutic treatments.

Infection preventionists, healthcare epidemiologists play key roles in promoting antimicrobial stewardship

Infection preventionists and healthcare epidemiologists play key roles in promoting effective antimicrobial stewardship in collaboration with other health professionals, according to a joint position paper published today by the Association for Professionals in Infection Control and Epidemiology (APIC) and the Society for Healthcare Epidemiology of America (SHEA) in their respective peer-review journals, the American Journal of Infection Control and Infection Control and Hospital Epidemiology.

FDA clears Alma Lasers' novel approach for treatment of nail fungus

For the 35 million people worldwide that suffer from Onychomycosis (nail fungus), a new, fast, effective approach to treatment is now available. Alma Lasers, Inc., a leader in laser, light, radiofrequency and ultrasound aesthetic and medical devices, is pleased to announce the introduction of its newest innovation for the Harmony(XL) multi-application, multi-technology platform, a novel approach for the treatment of nail fungus.

Healthy lactic acid bacteria in wild honey bees can fight bacterial infections

The stomachs of wild honey bees are full of healthy lactic acid bacteria that can fight bacterial infections in both bees and humans. A collaboration between researchers at three universities in Sweden ¬- Lund University, the Swedish University of Agricultural Sciences and Karolinska Institutet - has produced findings that could be a step towards solving the problems of both bee deaths and antibiotic resistance.

ITQB, REQUIMTE convert solid antibiotic ampicilin into an ionic liquid form

In a daring move into the biomedical arena, ITQB chemists from the Molecular Thermodynamics Lab and collaborators from REQUIMTE have managed to convert the solid antibiotic ampicilin into an ionic liquid form, a method that may be extended to other pharmaceutical compounds with benefits for their administration. The work is now published in Medicinal Chemistry Communications.

Abbott, GenLab collaborate to develop new assay for PLEX-ID automated microbial identification system

Abbott announced today it will collaborate with Genetics Laboratory, Inc. on the development of a molecular diagnostic test that will be designed to rapidly detect microorganisms that cause orthopedic infections.

Scientists determine chemical features of DHPS enzyme's active site

More than 70 years after the first sulfa drugs helped to revolutionize medical care and save millions of lives, St. Jude Children's Research Hospital scientists have determined at an atomic level the mechanism these medications use to kill bacteria. The discovery provides the basis for a new generation of antibiotics that would likely be harder for bacteria to resist and cause fewer side effects.

Unknown facets of biological mechanism that immune cells use for creating free radicals

Sometimes our immune defence attacks our own cells. When this happens in the brain we see neurodegenerative diseases such as dementia, Alzheimer's and Parkinson's disease. But if the the immune defence is inhibited, the results could be disastrous.
