Progress toward treating infections by silencing microbes' smartphones ScienceDaily Share     So disease-causing bacteria in the body finally have multiplied to the point where their numbers are large enough to cause illness. What's next? They get out their smartphones and whisper "Let's roll!" That's how an article in ACS' monthly Chemical Reviews describes the substances — "smartphones of the microbial world" — that bacteria use to transmit chemical signals that launch infections and monitor their environment. The authors describe progress toward understanding and blocking this biochemical chitchat, a development that could lead to new treatments for the growing problem of antibiotic-resistant infections.

New strain of swine flu emerges Reuters Share
The H1N1 swine flu virus may be starting to mutate, and a slightly new form has begun to predominate in Australia, New Zealand and Singapore, researchers reported. More study is needed to tell whether the new strain is more likely to kill patients and whether the current vaccine can protect against it completely, said Ian Barr of the World Health Organization Collaborating Center for Reference and Research on Influenza in Melbourne, Australia and colleagues. More 3 blood biomarkers may help identify patients at high risk for chronic kidney disease Medscape Medical News Share
Three biomarkers that can be tested in a single blood sample may help identify patients at high risk for chronic kidney disease, according to the results of a study reported online in the Journal of the American Society of Nephrology. The study cohort consisted of 2,345 participants who attended the sixth Framingham Offspring Study examination, conducted from 1995 to 1998. More Hundreds dead In Haiti. Fear cholera will spread to camps NPR Share
People in Port-au-Prince are waiting. Waiting for cholera to come. Reports from the ground in Haiti are saying it is not a matter of if, it is a matter of when the disease spreads to the capital. For now, only five people in Port-Au-Prince have been diagnosed with the disease, and they've been quarantined. They contracted it in the rural area where it first broke out. More New look at multitalented protein sheds light on mysteries of HIV ScienceDaily Share
New insights into the human immunodeficiency virus infection process, which leads to acquired immunodeficiency syndrome, may now be possible through a research method recently developed in part at the National Institute of Standards and Technology, where scientists have glimpsed an important protein molecule's behavior with unprecedented clarity. The HIV protein, known as Gag, plays several critical roles in the assembly of the human immunodeficiency virus in a host cell, but persistent difficulties with imaging Gag in a lab setting have stymied researchers' efforts to study how it functions.

Pelvic organ prolapse linked to genetic variations Medscape Medical News Share
A growing body of evidence suggests that genes figure significantly in the risk for pelvic organ prolapse (POP), researchers said at the American Urogynecologic Society 31st Annual Scientific Meeting. In the first genome-wide association analysis for POP, Peggy Norton, MD, from the University of Utah School of Medicine in Salt Lake City, presented evidence that at least six single-nucleotide polymorphisms are significantly associated with POP. More Prediction and diagnosis of autoimmune diabetes Clinical Laboratory News Share
The autoimmune forms of diabetes, which affects 2 to 4 million people, include type 1 diabetes, an estimated 5 percent to 10 percent of those with diabetes, and latent autoimmune diabetes in adults, estimated to be 5 percent to 10 percent of those diagnosed with type 2 diabetes. T1D, previously called insulin-dependent diabetes mellitus or juvenile onset diabetes, occurs when the body's immune system destroys the pancreatic β-cells that produce the hormone insulin involved in blood glucose regulation. To survive, affected individuals must take insulin. More CDC: One-third of US adults could have diabetes by 2050 HealthDay News via Bloomberg Businessweek Share
The number of American adults with diabetes could double or triple by 2050 if current trends continue, warns a federal government study. The number of new diabetes cases a year will increase from eight per 1,000 in 2008 to 15 per 1,000 in 2050, predicts the U.S. Centers for Disease Control and Prevention. By 2050, between one-fifth and one-third of all adults could have diabetes — with virtually all the increase attributed to type 2 diabetes, which is largely preventable. More |
