Unusual bacteria help balance the immune system in mice

Medical researchers have long suspected that obscure bacteria living within the intestinal tract may help keep the human immune system in balance. An international collaboration co-led by scientists at NYU Langone Medical Center has now identified a bizarre-looking microbial species that can single-handedly spur the production of specialized immune cells in mice.

Powerhouses in the cell dismantled

All of life is founded on the interactions of millions of proteins. These are the building blocks for cells and form the molecular mechanisms of life. The problem is that proteins are extremely difficult to study, particularly because there are so many of them and they appear in all sizes and weights. Now, Kris Gevaert from VIB/Ghent University and colleagues from the universities of Freiburg and Bochum have achieved a breakthrough in protein research.

New laryngoscope could make difficult intubations easier

AUGUSTA, Ga. – A new tool developed by a Medical College of Georgia resident and faculty member may make it easier to place assisted breathing devices under difficult circumstances.

About 2 percent of patients that undergo the process, called intubation, experience complications – regardless if it's performed in an emergency situation or prior to surgery.

New technologies help scholars analyze ancient Aramaic texts

New technologies and academic collaborations are helping scholars at the University of Chicago analyze hundreds of ancient documents in Aramaic, one of the Middle East's oldest continuously spoken and written languages.

3 meals a day keep the fungi away

October 15, 2009 - (BRONX, NY) - The fact that they eat a lot – and often – may explain why most people and other mammals are protected from the majority of fungal pathogens, according to research from Albert Einstein College of Medicine of Yeshiva University.

The research, published in the Journal of Infectious Diseases, showed that the elevated body temperature of mammals – the familiar 98.6o F or 37o C in people – is too high for the vast majority of potential fungal invaders to survive.

Being a standout has its benefits...if you're a paper wasp

ANN ARBOR, Mich.---Standing out in a crowd is better than blending in, at least if you're a paper wasp in a colony where fights between nest-mates determine social status.

That's the conclusion of a study by University of Michigan researchers published online this week in the journal Evolution.

"It's good to be different, to wear a nametag advertising your identity," said graduate student Michael Sheehan, who collaborated on the research with evolutionary biologist Elizabeth Tibbetts.

New model could help emergency room physicians diagnose acute heart failure

TORONTO, Ont., October 15, 2009 — Researchers at St. Michael's Hospital have developed the first mathematical model in cardiology and emergency medicine to more quickly and reliably diagnose acute heart failure (AHF) in emergency room patients. Research findings published in the Journal of the American College of Cardiology, have been shown to help physicians diagnose AHF with greater accuracy.

New essay by University of Miami law professor analyzes the story of a Haitian immigrant

CORAL GABLES, FL (October 14, 2009) – University of Miami Law Professor Anthony V. Alfieri has recently authored an essay titled, "Discovering Identity in Civil Procedure" that explores the story of Floride Norelus, an undocumented Haitian immigrant. The backdrop for Norelus's story comes out of Ariela J. Gross's new book "What Blood Won't Tell: A History of Race on Trial in America." In the book, Gross expands on slavery, race, and antebellum trials to investigate the changing meaning of identity in law and litigation.

New data showed type 2 diabetes patients experienced greater blood sugar reductions

DEERFIELD, Ill., October 14, 2009 – A study, published online in the journal Current Medical Research and Opinion, showed that a greater percentage of patients with type 2 diabetes treated with the fixed-dose combination ACTOplus met® (pioglitazone HCl and metformin HCl) as initial therapy reached the study goal of hemoglobin A1c (HbA1c) of ≤7 percent compared to either component alone. Safety and tolerability of ACTOplus met therapy were evaluated by rate of drug discontinuation and treatment-emergent adverse events.

Biological barcode readers hold out promise of universal vaccines

Veterinary scientists have made a discovery that promises to deliver a new approach to fast development of cheap vaccines that are effective in all mammals – not just humans or another particular species. They propose that by harnessing the system that reads the biological 'barcodes' of infectious microbes such as food poisoning bacteria, flu viruses and protozoa that cause malaria, one vaccine could be made to prevent a particular disease in all mammals.

Outfoxing pox: Developing a new class of vaccine candidates

In the annals of medicine, Edward Jenner's 1796 vaccination of a young boy against smallpox, using fluid from cowpox blisters, remains a landmark case. In a new study, Kathryn Sykes, a researcher at Arizona State University's Biodesign Institute and her colleagues have taken a fresh look at cowpox. Their findings, appearing in the advanced online issue of Virology, demonstrate that this ancient pathogen still has much to teach us, and may hasten development of novel vaccines against smallpox and other pox-like diseases.

Treatment not testicular cancer poses greatest risk to survivors' long-term health

Testicular cancer survivors can face an increased risk of long-term illness, not because of the malignancy, but the highly effective treatment they receive, according to a study in the urology journal BJUI.

Researchers from the Norwegian Radium Hospital at the University of Oslo found that the number of problems faced by survivors are higher than generally thought, because clinicians only report those that are life-threatening or require medical intervention. Awareness of this discrepancy has led to a greater focus on patient-reported outcomes.

New method proposed to calculate reduction in road accident deaths

A team of engineers from the University of Almería (UAL) has developed a methodology to help meet the EU objective of cutting road deaths by 50% between 2000 and 2010. The researchers have calculated the relevant amount for each country according to its starting point, and have done the same for each of the Spanish provinces.

Healthy diet and exercise alone unlikely to cure sleep apnea

Westchester, Ill. – A study in the Oct. 15 issue of the Journal of Clinical Sleep Medicine found that while a strict diet and exercise program may benefit obese patients with mild to moderate obstructive sleep apnea (OSA), it is unlikely to eliminate the condition.

Resveratrol in red grapes may squeeze out diabetes

DALLAS – Oct. 15, 2009 – A naturally produced molecule called resveratrol, found in the skin of red grapes, has been shown to lower insulin levels in mice when injected directly into the brain, even when the animals ate a high-fat diet.
