Anxiety’s hidden cost

The researchers, Professor Michael Eysenck and Dr Nazanin Derkshan, designed several experiments to explore the effects of anxiety on our ability to perform tasks such as avoiding distractions on a computer screen, when reading a story, or solving a series of simple mathematics problems.

Research shows how obesity sets the stage for diabetes

Obesity is probably the most important factor in the development of insulin resistance, but science's understanding of the chain of events is still spotty. Now, researchers at the Salk Institute for Biological Studies have filled in the gap and identified the missing link between the two.

Transplant drug Rapamycin stimulates immune memory

Rapamycin, a drug given to transplant recipients to suppress their immune systems, has a paradoxical effect on cells responsible for immune memory, scientists at the Emory Vaccine Center have discovered.

Big disparities in the treatment of arrhythmias across Europe

The latest statistics regarding the use of pacemakers and implantable cardiac devices in Europe was presented on Sunday 21 June, at EUROPACE 2009, the meeting of the European Heart Rhythm Association (EHRA) which takes place in Berlin, Germany from 21 to 24 June.

Goby fish may bring new drugs for high blood pressure

Medical scientists at the University of Leicester are investigating how a species of fish from the Pacific Ocean could help provide answers to tackling chronic conditions such as hereditary high blood pressure and kidney disease.

Caucasians more likely to develop Ewing's sarcoma than other races

The largest analysis of its kind has found that Caucasians are much more likely that people in other racial/ethnic groups to develop a rare bone and soft tissue cancer called Ewing's sarcoma. In addition, among Caucasians with this cancer, men are more likely to die than women.

Study exposes tobacco industry's ‘shonky’ behaviour

Researchers in the United States have revealed that tobacco companies have continually changed the ingredients and the design of their cigarettes over time without alerting smokers.

HIV antibody tests unreliable for early infections in teens

A previously healthy teenager shows up at the doctor's office with a sore throat, fever, aches and general malaise. Routine blood tests are normal, an HIV test comes back negative, and the pediatrician sends the patient home with a diagnosis of acute viral infection.

New discovery on how botulism paralyzes nerve cells

New structures of a botulism toxin interacting with a mimic of the nerve-cell protein it destroys suggest new ways to block this often-fatal interaction. Indeed, the mimic molecules have such high affinity for the toxin and bind to it so tightly that they themselves could possibly serve as anti-toxin drugs with further modification, the researchers said.

NCRI launches template for sharing research data and samples

The National Cancer Research Institute (NCRI) has launched a broad policy template on sharing research data and biological samples, which will help to streamline the governance requirements for biomedical research which uses such resources.

Researchers develop promising new breast cancer diagnostic marker

Indiana University School of Medicine researchers have developed a new breast cancer diagnostic marker that could enable physicians to more easily determine which patients have a less aggressive form of the disease that may not require chemotherapy treatment.

Medical insurers' billing claims can help researchers track patient complications

Billing claims from health insurance companies can provide insights on the long-term health of kidney transplant patients, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN).

Targeting tumor behavior may find new anti-cancer agents

Ohio State University cancer researchers have used computational and genomic methods to identify possible anti-cancer agents that may block a particular kind of tumor behavior. The agents target multiple genes associated with that behavior at one time.

Scientists edit genes in human stem cells

Researchers at the Johns Hopkins School of Medicine have successfully edited the genome of human- induced pluripotent stem cells, making possible the future development of patient-specific stem cell therapies. Reporting this week in Cell Stem Cell, the team altered a gene responsible for causing the rare blood disease paroxysmal nocturnal hemoglobinuria, or PNH, establishing for the first time a useful system to learn more about the disease.

Improved toxicology test method

Researchers at Oregon State University recently completed the largest animal study ever done in the field of toxicology, and the findings challenge some basic concepts about how to determine what level of a cancer-causing compound can be considered safe.

Gout gene discovered

Having partnered last year with an international team that surveyed the genomes of 12,000 individuals to find a genetic cause for gout, Johns Hopkins scientists now have shown that the malfunctioning gene they helped uncover can lead to high concentrations of blood urate that forms crystals in joint tissue, causing inflammation and pain - the hallmark of this disease.

Antibiotics diminish diversity of helpful gutmicrobes

It's common knowledge that a protective navy of bacteria normally floats in our intestinal tracts. Antibiotics at least temporarily disturb the normal balance. But it's unclear which antibiotics are the most disruptive, and if the full array of "good bacteria" return promptly or remain altered for some time.
