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.

Novel anti-leukemia compound with little toxicity successfully treats zebrafish

A novel anti-leukemia compound with little toxicity successfully treated zebrafish with T-cell acute lymphoblastic leukemia (T-ALL), suggesting its potential to become a new highly targeted therapy for humans - even those resistant to conventional therapies - according to results from a study published online today in Blood, the Journal of the American Society of Hematology (ASH).

Delivering chemotherapy drugs with nanobubbles more deadly to cancer cells

Using light-harvesting nanoparticles to convert laser energy into "plasmonic nanobubbles," researchers at Rice University, the University of Texas MD Anderson Cancer Center and Baylor College of Medicine (BCM) are developing new methods to inject drugs and genetic payloads directly into cancer cells.

Only few women consume aspirin to reduce risk of heart disease

Heart disease is the leading cause of death among women, and evidence-based national guidelines promote the use of daily aspirin for women at increased risk for cardiovascular disease. However, less than half of the women who could benefit from aspirin are taking it, according to an article in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc.

Causes of traumatic brain injury in older population

As the population ages in western countries, traumatic brain injury (TBI) resulting mainly from falls is on the rise among the elderly, introducing new complications and treatment challenges, according to an article in Journal of Neurotrauma, a peer-reviewed journal from Mary Ann Liebert, Inc.

Genetic counseling does not help parents in disclosing their breast cancer information to children

When a mother undergoes genetic testing to determine whether she carries a gene for hereditary breast cancer, the parents must then decide whether and how to share this risk information with their children.

TLR4/MD-2 protein complex triggers morphine-induced inflammation

A University of Colorado Boulder-led research team has discovered that two protein receptors in the central nervous system team up to respond to morphine and cause unwanted neuroinflammation, a finding with implications for improving the efficacy of the widely used painkiller while decreasing its abuse potential.

Platelet activating factor plays a crucial role in development of graft-versus-host disease

A new discovery in mice may lead to new treatments that could make bone marrow transplants more likely to succeed and to be significantly less dangerous.

Study provides new information on why A-T disease attacks the brain

Rutgers scientists think they have found a way to prevent and possibly reverse the most debilitating symptoms of a rare, progressive childhood degenerative disease that leaves children with slurred speech, unable to walk, and in a wheelchair before they reach adolescence.

Nmnat enzyme plays a critical role in nerve injury

A new animal model of nerve injury has brought to light a critical role of an enzyme called Nmnat in nerve fiber maintenance and neuroprotection.

Hyperinsulinemia itself not a cause of atherosclerosis

A number of studies have shown that excess insulin circulating in the bloodstream is a major independent risk factor for cardiovascular disease. However, a new study from Joslin Diabetes Center finds that this condition, called hyperinsulinemia, is itself not a cause of atherosclerosis.

New method uses E. coli bacteria to engineer human therapeutic glycoproteins

Escherichia coli - a bacteria considered the food safety bane of restaurateurs, grocers and consumers - is a friend. Cornell University biomolecular engineers have learned to use E. coli to produce sugar-modified proteins for making pharmaceuticals cheaper and faster.

Defects in schizophrenia-risk genes and environmental stress lead to abnormal brain development

Working with genetically engineered mice and the genomes of thousands of people with schizophrenia, researchers at Johns Hopkins say they now better understand how both nature and nurture can affect one's risks for schizophrenia and abnormal brain development in general.

Fruit flies too get kidney stones

Research on kidney stones in fruit flies may hold the key to developing a treatment that could someday stop the formation of kidney stones in humans, a team from Mayo Clinic and the University of Glasgow found.

AACR to honor PU professor with Award for Outstanding Achievement in Cancer Research

A researcher from The Cancer Institute of New Jersey (CINJ) and Princeton University who is helping to advance the molecular understanding of cancer metastasis is being recognized for his work by cancer specialists from around the globe.

U of S professor receives Canada Gairdner Wightman Award

University of Saskatchewan Professor Emeritus Lorne Babiuk has been awarded the prestigious Canada Gairdner Wightman Award in recognition of his accomplishments over three decades that include leading the U of S Vaccine and Infectious Disease Organization (VIDO) to become a world centre for vaccine research, training and development.

Alpha-5 GABA type A receptors linked to anesthesia-related memory loss

A drug targeting one specific receptor may provide the first effective approach to treatment for the common problem of memory loss after surgery and anesthesia, according to an experimental study in the April issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society.

Alzheimer's may spread through connected neurons

Alzheimer's disease and other forms of dementia may spread within nerve networks in the brain by moving directly between connected neurons, instead of in other ways proposed by scientists, such as by propagating in all directions, according to researchers who report the finding in the March 22 edition of the journal Neuron.

Obesity gene mutation identified in mice

A new study has found why a mutation in a particular gene can lead to obesity. Mouse experiments suggested the body's message to “stop eating” was blocked if the animals had the mutation. The study, published in Nature Medicine, said the brain's response to appetite hormones was being disrupted.

Study determines why blood oranges develop anthocyanin pigments

The anthocyanin pigments that provide the "blood" color of blood oranges are not produced in significant amounts unless the fruit is exposed to cold conditions during its development or post-harvest. No cold exposure means poor anthocyanin production and the loss of the entire crop. This means that blood oranges can be grown in many areas of the world, but they are most likely to be exposed to the correct temperature conditions in only a few regions, including their major area of production in Sicily.
