New way to culture stem cells in 3D environment

Stem cells are the body's mechanics, repairing damaged tissues and organs. Because these cells are able to grow into any type of cell in the body, scientists believe they hold the key to groundbreaking new therapies. To help further this research, scientists from the University of Victoria have found a new way to culture cells in 3D- a significant step forward for regenerative medicine.

Researchers confirm how food poisoning bacteria hijack cell's sense of direction

Working in the emerging field of systems biology, UT Southwestern Medical Center researchers mathematically predicted how bacteria that cause food poisoning hijack a cell's sense of direction and then confirmed those predictions in living cells.

U.S. panel may re-evaluate bird flu research after scientists present new data about risks to humans

Speaking at the American Society for Microbiology's (ASM) Biodefense and Emerging Diseases Research meeting in Washington, D.C., on Wednesday, Ron Fouchier, the leader of the team at Erasmus Medical Center in the Netherlands that genetically altered the H5N1 bird flu virus, making it transmissible among ferrets and "touching off public fears of a pandemic, said that the virus he created was neither as contagious nor as dangerous as people had been led to believe, prompting the United States government to ask that the experiments be re-evaluated by a government advisory panel that recommended in December that certain details of the work be kept secret and not published," the New York Times reports.

IOM report identifies options that could further improve information obtained from pediatric studies

Federal laws that motivate or require drug and biologic developers to conduct pediatric studies have yielded beneficial information to guide the use of medications in children, says a new report by the Institute of Medicine. Still, studies involving children continue to be limited, especially in certain areas such as medications' use in newborns and long-term safety and effectiveness in children.

Researchers observe how cholera decimates competing bacteria and human cells

Bacteria live in a state of perpetual warfare, with different species battling for dominion over their competitors and when pathogen, over their infected host. New research suggests that the human pathogen Vibrio cholerae, which causes the disease cholera, kills off its microbial rivals by jabbing them with a spring-loaded poison dagger.

Scientists discover new pathway necessary for infection to occur with N. gonorrhoeae

Researchers from Boston University School of Medicine (BUSM) have for the first time identified a novel pathway that is necessary for infection to occur with the pathogen Neisseria gonorrhoeae, which is responsible for the second most common infectious disease worldwide, gonorrhea.

WATCHMAN device may prevent stroke in AF patients

In the United States alone, approximately 6 million people suffer from an irregular heartbeat called atrial fibrillation (AF), and since the incidence increases with age, it is predicted that 15.9 million Americans will be affected by 2050. The most devastating side effect of AF is stroke, but a new device from Boston Scientific may prevent them from occurring.

Bird flu may be more common and less deadly: Study finds

The H5N1 influenza virus commonly called “bird flu” or “avian flu” could be more prevalent and less deadly than health officials had thought, according to a new study published online (Feb. 23) by the journal Science.

Two new analyses raise questions about mortality rate of bird flu

In an analysis published Thursday in the online edition of the journal Science, a team led by virologist Peter Palese of Mount Sinai School of Medicine in New York argue the mortality rate from H5N1 bird flu is under one percent, much lower than the WHO's estimated fatality rate of 59 percent, Reuters reports.

Combined bioactive peptides successfully stimulate wound healing

Researchers have combined bioactive peptides to successfully stimulate wound healing. The in vitro and in vivo study, published today in PLoS ONE, demonstrates that the combination of two peptides stimulates the growth of blood vessels and promotes re-growth of tissue. Further development of these peptides could lead to a new treatment for chronic and acute wounds.

MRSA strain in food animals concerns experts

The strain of staph, known as methicillin-resistant Staphylococcus aureus, or MRSA CC398, most often infects farm workers who come in contact with infected pigs, turkeys, or cows. Now the strain of bacteria has been found in about half of meat samples taken throughout the country. The researchers say that the indiscriminate use of antibiotics in livestock used for food is to blame for the infection's drug resistance.

Candida albicans can sense immune status of host cells and evade them

Glen Palmer, PhD, Assistant Professor of Microbiology, Immunology & Parasitology at LSU Health Sciences Center New Orleans, was part of an international research team led by Luigina Romani, MD, at the University of Perugia, that discovered opportunistic fungi like Candida albicans can sense the immune status of host cells and adapt, evading immune system defenses.
