New method for direct identification of antigens

The immune system is a vital part of our defenses against pathogens, but it can also attack host tissues, resulting in autoimmune disease. The antigens that induce destructive immune reactions can now be identified directly - without any prior knowledge of their possible structure.

Study shows how biofilms form on implanted devices

Bacteria such as Staphylococcus aureus, the 'superbug' behind MRSA, can be a major problem for patients who have a medical implant, such as a replacement heart valve or pacemaker.

Reducing iron levels in blood plasma may protect brain from changes related to AD

Alzheimer's disease (AD) is now the sixth leading cause of death among Americans, affecting nearly 1 in 8 people over the age of 65. There is currently no treatment that alters the course of this disease. However, an increasing amount of evidence suggests that changes in the way the body handles iron and other metals like copper and zinc may start years before the onset of AD symptoms. A new study shows that reducing iron levels in blood plasma may protect the brain from changes related to AD.

Avid Radiopharmaceuticals receives FDA approval for Amyvid to treat AD

The U.S. Food and Drug Administration today approved Amyvid (Florbetapir F 18 Injection) a drug for Positron Emission Tomography (PET) imaging of the brain in adults who are being evaluated for Alzheimer's Disease (AD) and other causes of cognitive decline.

Soon a vaccine that targets 90% of all cancers

Results from the safety trial - on patients with blood cancer - found all had greater immunity to the disease after receiving the vaccine. Three of the seven patients who have completed the treatment are now free of the condition.

Biovest seeks Health Canada approval of BiovaxID for follicular NHL

Biovest International, Inc., a majority-owned subsidiary of Accentia Biopharmaceuticals, Inc., today announced that Biovest is seeking marketing approval in Canada for BiovaxID, its personalized cancer vaccine for the treatment of follicular non-Hodgkin's lymphoma, an incurable cancer of the immune system.

Two CNVs may increase risk of aggressive prostate cancer

An international research team led by Weill Cornell Medical College investigators have discovered two inherited-genetic deletions in the human genome linked to development of aggressive prostate cancer.

Study: Body and head lice are the same species

A new study offers compelling genetic evidence that head and body lice are the same species. The finding is of special interest because body lice can transmit deadly bacterial diseases, while head lice do not.

KLF15 gene governs the body's ability to burn fat during exercise

While exercise is accepted universally as the most beneficial prescription physicians can write for patients, little is known about the molecular mechanisms that generate its widespread health benefits. Researchers from Case Western Reserve School of Medicine have shed light on this mystery by discovering that a genetic factor, Kruppel-like Factor 15 (KLF15), governs the body's ability to burn fat during exercise.

Black fly's blood-sucking tactics may be used for medical advancement

Black flies drink blood and spread disease such as river blindness-creating misery with their presence. A University of Georgia study, however, proves that the pesky insects can be useful.

Nuron Biotech licenses DNA amyloid beta 42 vaccine for AD

Nuron Biotech, Inc. today announced it has licensed from VITRUVIAN BioMedical, Inc. a gene-based (DNA) amyloid beta 42 (Aβ42) vaccine in preclinical development for Alzheimer's disease (AD).

Two Rev-erb proteins work together to control fat metabolism

The 24-hour internal clock controls many aspects of human behavior and physiology, including sleep, blood pressure, and metabolism. Disruption in circadian rhythms leads to increased incidence of many diseases, including metabolic disease and cancer. Each cell of the body has its own internal timing mechanism, which is controlled by proteins that keep one another in check.

Research on how cells cope with stress could lead to more effective cancer treatment

Both radiation and many forms of chemotherapy try to kill tumors by causing oxidative stress in cancer cells. New research from USC on a protein that protects cancer and other cells from these stresses could one day help doctors to break down cancer cells' defenses, making them more susceptible to treatment.

NIMH honors SUNY Downstate professor with MERIT award

Todd C. Sacktor, M.D., distinguished professor of physiology and pharmacology and of neurology at SUNY Downstate Medical Center, has received a MERIT (Method to Extend Research in Time) award from the National Institute of Mental Health (NIMH) for his research on memory.

Poultry producers still use FDA-banned antibiotics

In a joint study, researchers at the Johns Hopkins Bloomberg School of Public Health and Arizona State University found evidence suggesting that a class of antibiotics previously banned by the U.S. government for poultry production is still in use. Results of the study were published March 21 in Environmental Science & Technology.

Scientists identify how Clec9A protein recognises foreign invaders

The discovery of how a vital immune cell recognises dead and damaged body cells could modernise vaccine technology by 'tricking' cells into launching an immune response, leading to next-generation vaccines that are more specific, more effective and have fewer side-effects.

New technique reveals another piece of spectrum's genetic architecture

There is little argument among experts that autism spectrum disorders (ASD), complex developmental disabilities that vary widely in their severity, are caused by both genetic and environmental factors. Advances in genome sequencing now permit scientists to uncover specific mutations in DNA that are associated with ASD at unprecedented resolution. Such data are vital to understanding the genetic basis of the disorder.

Positive effect of tafamidis on neurological degeneration

Tafamidis meglumine was approved in November 2011 for the treatment of transthyretin amyloidosis in adults. This rare disorder is caused by a defective gene and is associated with progressive nerve damage (neurological degeneration) that tafamidis is supposed to delay.

TAM protein complex - a potential antibacterial target

Scientists could produce new antibacterial treatments by disarming the molecular pumps bacteria use to bring disease causing molecules in contact with animals and humans.

Key finding in regulation of intraocular pressure in glaucoma

A six-year collaboration between two faculty members of Bascom Palmer Eye Institute of the University of Miami Miller School of Medicine has yielded new insight regarding the regulation of intraocular pressure (IOP) in glaucoma - an irreversible blinding disease that causes progressive visual impairment due to optic nerve damage and is the leading cause of blindness worldwide.
