Case Western Reserve researcher discovers new antivirulence drugs against MRSA and strep

Menachem Shoham, PhD, associate professor of biochemistry at Case Western Reserve University School of Medicine, has discovered novel antivirulence drugs that, without killing the bacteria, render Methicillin Resistant Staphylococcus Aureus (MRSA) and Streptococcus pyogenes, commonly referred to as strep, harmless by preventing the production of toxins that cause disease.

Some gut microbes increase absorption of dietary fats

You may think you have dinner all to yourself, but you're actually sharing it with a vast community of microbes waiting within your digestive tract. A new study from a team including Carnegie's Steve Farber and Juliana Carten reveals that some gut microbes increase the absorption of dietary fats, allowing the host organism to extract more calories from the same amount of food.

Synthetic biology pioneer wins 2012 Heinz Award

Jay Keasling, a leading authority and pioneer on synthetic biology who has engineered microbial "factories" to manufacture an affordable version of a frontline antimalarial drug and biofuel substitutes for gasoline, diesel and jet fuel, has won a 2012 Heinz Award, which is presented by the Heinz Family Foundation and carries with it a cash prize of $250,000.

Positive data from Tetraphase Pharmaceuticals’ eravacycline Phase 2 trial on cIAI

Tetraphase Pharmaceuticals, Inc., a clinical-stage life science company developing novel antibiotics effective against antibiotic-resistant bacteria, presented new, positive Phase 2 clinical data on its lead drug candidate, eravacycline (TP-434), on September 11, 2012, at the 52nd Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) in San Francisco, CA.

New model reveals how immune system functions under conditions of neutropenia

Cancer chemotherapy can be a life-saver, but it is fraught with severe side effects, among them an increased risk of infection. Until now, the major criterion for assessing this risk has been the blood cell count: if the number of white blood cells falls below a critical threshold, the risk of infection is thought to be high.

Scripps scientists discover new antibody-discovery technique

Scientists at The Scripps Research Institute have found a new technique that should greatly speed the discovery of medically and scientifically useful antibodies, immune system proteins that detect and destroy invaders such as bacteria and viruses. New methods to discover antibodies are important because antibodies make up the fastest growing sector of human therapeutics; it is estimated that by 2014 the top-three selling drugs worldwide will be antibodies.

Nonsurgical treatment achieves periodontitis improvements regardless of smoking

Both smokers and nonsmokers with the chronic inflammatory disease periodontitis have significantly improved clinical markers, including probing depth and plaque index, after nonsurgical periodontal therapy, show study results.

Strep throat should be treated with penicillin or amoxicillin: IDSA guidelines

Although people often say they have "strep" throat, most sore throats actually are caused by a virus, not streptococcus bacteria, and shouldn't be treated with antibiotics, suggest guidelines published by the Infectious Diseases Society of America (IDSA). Antibiotics are ineffective against viruses.

Methodist Hospital develops new technology to rapidly detect drug-resistant TB

Technology developed by scientists at The Methodist Hospital Research Institute could halve the time it takes to diagnose tuberculosis infection, and also tell doctors in a day or two whether the bacteria are drug resistant -- a process that currently takes weeks. Initial tests of the device were recently described in Scientific Reports, a Nature online journal.

Data from Sangamo BioSciences’ SB-728-T Phase 1 clinical programs on HIV/AIDS

Sangamo BioSciences, Inc. announced that data from its Phase 1 clinical programs to develop SB-728-T, a novel therapeutic approach designed to generate a "functional cure" for HIV/AIDS, were presented at the 52nd Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC).

Oxyphenbutazone can kill drug resistant TB

An off-patent anti-inflammatory drug that costs around two cents for a daily dose in developing countries has been found by researchers at Weill Cornell Medical College to kill both replicating and non-replicating drug resistant tuberculosis in the laboratory -- a feat few currently approved TB drugs can do, and resistance to those is spreading.

Automated system for mapping protein-DNA interactions

Since the sequencing of the human genome in 2001, all our genes - around 20,000 in total - have been identified. But much is still unknown - for instance where and when each is active. Next to each gene sits a short DNA segment, and the activity of this regulatory segment determines whether the gene will be turned on, where and how strongly.

Research roundup: Reducing risk in shared savings programs

The Design And Application Of Shared Savings Programs: Lessons From Early Adopters --"Shared savings programs reward providers for holding spending below specific targets, thus introducing a level of financial accountability not present in strictly volume-based payment models, such as fee-for-service," researchers write.

Simple low-cost biosensor to detect contaminated drinking water

Diarrheal disease is the second leading cause of death in children under five years old - killing as many as 1.5 million children worldwide every year. These startling statistics from the World Health Organization (2009) point to the reason why a group of undergraduate students from Arizona State University is working to develop a low-cost biosensor - a simple device that would detect contaminated drinking water.

Study sheds light on how high-fibre diet affects the gut environment

Savvy consumers and health professionals know that fibre is an essential nutrient associated with important health benefits, yet barriers such as overall poor tolerance to higher-fibre diets may be why average intake is far less than experts recommend.

Boston researchers develop neonatal mouse model of sepsis

Sepsis, or bacterial infection of the bloodstream, is a grave, hard-to-diagnose threat in premature newborns in the NICU. Even when it's detected and treated with antibiotics, its inflammatory effects can harm fragile babies' development. Now, researchers at Boston Children's Hospital have modeled the effects of sepsis on the unique newborn immune system, using mice.

Nutritional benefits of organic foods questioned

Strong evidence to support the supposed nutritional benefits of eating organic over conventional foods is lacking in the scientific literature, show results from a systematic review.

Johnson & Johnson Vision Care develops new educational resource

Soft contact lenses are worn safely and comfortably by millions of people worldwide, and have a long history of providing wearers with a safe and effective form of vision correction when properly worn and cared for. However, research shows that many contact lens wearers are significantly non-compliant in virtually all active steps involved in soft contact lens wear, including hand washing, case hygiene, lens disinfection, and following the recommended lens replacement schedule.

Antibiotics: facts and fictions: an interview with Dr Philippa Binns, clinical adviser at NPS MedicineWise

Antibiotics are medicines used to treat infections or diseases caused by bacteria, such as some respiratory tract infections (including pneumonia and whooping cough), urinary tract infections, skin infections and infected wounds.

New strategy for outsmarting cancer through its own social intelligence

In the face of mounting evidence that cancer cells communicate, cooperate and even engage in collective decision-making, biophysicists and cancer researchers at Rice University, Tel Aviv University and Johns Hopkins University are suggesting a new strategy for outsmarting cancer through its own social intelligence.
