Scientists identify single prion protein that causes neuronal death

Scientists from the Florida campus of The Scripps Research Institute have identified a single prion protein that causes neuronal death similar to that seen in "mad cow" disease, but is at least 10 times more lethal than larger prion species.

IKBKE protein plays two roles in tobacco-related NSCLC

Researchers at Moffitt Cancer Center in Tampa, Fla., have discovered that the immune response regulator IKBKE (serine/threonine kinase) plays two roles in tobacco-related non-small cell lung cancers. Tobacco carcinogens induce IKBKE and, in turn, IKBKE induces chemotherapy resistance.

Study identifies new gene variants linked with risk of T2D

The largest genetics study to date of type 2 diabetes (T2D) has identified new gene variants associated with risk for the common metabolic disease. An international scientific consortium, studying multiethnic populations, uncovered genes that may point to biological targets for developing more effective drugs for T2D.

New link between beta-arrestin and short-term memory

Biomedical scientists at the University of California, Riverside have identified a new link between a protein called beta-arrestin and short-term memory that could open new doors for the therapeutic treatment of neurological disorders, particularly Alzheimer's disease.

Cancer-related fatigue linked to muscle mass and strength

Many patients with advanced cancer suffer from cachexia, a condition also called body-wasting or wasting syndrome, which causes significant weight loss, extreme fatigue and reduces quality of life.

Gene therapy succeeds in the second blind eye for three patients

Three people have now have reported a dramatic improvement in vision after having gene therapy in both eyes after having lost their eyesight as children.

Early-life farm environment increases number of regulatory T-lymphocytes

Immunological diseases, such as eczema and asthma, are on the increase in westernised society and represent a major challenge for 21st century medicine. A new study has shown, for the first time, that growing up on a farm directly affects the regulation of the immune system and causes a reduction in the immunological responses to food proteins.

Women less satisfied with pain control after TKR surgery

Increased pain following surgery has long been linked to anxiety and "catastrophizing," an extreme response to stress. In a new study presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), 97 patients - men and women - who were about to undergo minimally invasive total knee replacement (TKR) surgery, completed a brief survey to quantify their level of anxiety, as well as their typical level of anxiety and potential for catastrophizing. Pain data was then collected for seven days following surgery.

DF/CHCC specialists recommend genetic counseling for children with Li-Fraumeni syndrome

Genetic specialists at Dana-Farber/Children's Hospital Cancer Center (DF/CHCC) are recommending that children being treated for sarcoma should be offered genetic counseling for Li-Fraumeni syndrome, a rare condition that greatly raises a person's risk of developing additional cancers.

Study determines prevalence of vitamin D deficiency among post menopausal women with DRF

Wrist fractures, also called distal radius fractures (DRF), are among the most common osteoporosis-related fractures occurring on average 15 years earlier than hip fractures. As vitamin D deficiency has recently been linked with muscle weakness, increased fall risks, and bone fractures, investigators sought to determine the prevalence of vitamin D deficiency among post menopausal women with DRF.

Study examines dimensional structure linked with DSM antisocial personality disorder criteria

With no lab tests to guide the clinician, psychiatric diagnostics is challenging and controversial. Antisocial personality disorder is defined as "a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood," according to the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) of the American Psychiatric Association.

First sign of coronary heart disease in men could be death

The healthy heart movement in recent years has focused largely on heart disease as the No. 1 killer of women. But the same statistic is true for men, and the reality is grim: The first sign that a man has coronary heart disease could be death, says one University of Alabama at Birmingham expert.

Tailoring TB treatment based on a patient's genetic sequence

A gene that influences the inflammatory response to infection may also predict the effectiveness of drug treatment for a deadly form of tuberculosis.

Study finds 77% of trauma patients with vitamin D deficiency

New research presented at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) found that 77 percent of trauma patients had deficient or insufficient levels of vitamin D.

Roche’s new breast cancer drug Pertuzumab up for FDA review

U.S. health regulators, the Food and Drugs Administration (FDA) has granted a priority review for an experimental Roche breast cancer drug that in clinical trials added six months to the time before the disease worsened. Pertuzumab approval decision is due by June 8th this year. It could be used with Herceptin in HER2-positive patients. This was announced by Roche Holding AG's Genentech unit on Tuesday.

Bread to blame for too much salt in American diet: CDC report

According to the latest figures released by the Centers for Disease Control and Prevention (CDC) this Tuesday, nine out of 10 American adults consume too much salt.

Three new targeted drugs can lead to fatal cancer complications

Treatment with three relatively new "targeted" cancer drugs has been linked to a slightly elevated chance of fatal side effects, according to a new analysis led by scientists at Dana-Farber Cancer Institute. They added that the risk remains low, but should be taken into account by physicians and patients.

Inhibiting MET signaling in glioblastoma has major therapeutic value

A recent discovery by Van Andel Research Institute (VARI) scientists enables the prediction of patient sensitivity to proposed drug therapies for glioblastoma - the most common and most aggressive malignant brain tumor in humans.

Researchers discover how SHP-2 genetic defect may result in heart malformation

UNC researchers have discovered how the genetic defect underlying one of the most common congenital heart diseases keeps the critical organ from developing properly. According to the new research, mutations in a gene called SHP-2 distort the shape of cardiac muscle cells so they are unable to form a fully functioning heart.

Researchers describe genetic basis of endometriosis

Researchers at Yale School of Medicine have, for the first time, described the genetic basis of endometriosis, a condition affecting millions of women that is marked by chronic pelvic pain and infertility. The researchers' discovery of a new gene mutation provides hope for new screening methods.
