New genetic signature may predict NSCLC patients at risk of relapse

A new genetic signature identified by Spanish researchers may provide doctors with robust and objective information about which patients with early stage lung cancer are at low or high risk of relapse following surgery, investigators report at the 3rd European Lung Cancer Conference in Geneva. Their work also opens new avenues for immunotherapy for lung cancer.

Study explains why some people develop kidney stones and others do not

Kidney stones strike an estimated 1 million Americans each year, and those who have experienced the excruciating pain say it is among the worst known to man (or woman).

BCCA, UBC scientists identify new breast cancer genes

Scientists at the BC Cancer Agency and University of British Columbia have identified new breast cancer genes that could change the way the disease is diagnosed and form the basis of next-generation treatments.

Brain size and IQ secret may lie in genes: Study

The study, conducted by a team of more than 200 scientists from 100 institutions worldwide, measured the size of the brain and its memory centers in thousands of MRI images from 21,151 healthy people while simultaneously screening their DNA. According to the researchers, a variant in a gene called HMGA2 affected the brain size, as well as a person's intelligence.

Blood test to diagnose depression in adolescents

Researchers have developed a blood test that can diagnose depression in teens, a step they hope will lead to a better way to identify the disorder in young people. At present diagnosing depression depends entirely on a patient's willingness to report symptoms. For teens, the diagnosis is particularly challenging, given the natural emotional ups and downs of adolescence.

Genetic reach of autism may extend to half siblings

When a child has autism, siblings are also at risk for the disorder. New research from Washington University School of Medicine in St. Louis shows that the genetic reach of the disorder often extends to half siblings as well.

Genetically modified mouse mimics key features of Charcot-Marie-Tooth disease

A team of scientists from the University of Missouri created a genetically modified mouse that mimics key features of Charcot-Marie-Tooth disease, an inherited neuromuscular disease affecting approximately 150,000 people in the United States.

New text on nursing of autism spectrum disorder

The growing number of children and adults on the autism spectrum represent a growing need for quality health care that is sensitive to the issues they face. This is the premise and challenge behind a new text, Nursing of Autism Spectrum Disorder: Evidence-based Integrated Care across the Lifespan (Springer, April 2012), edited by Dr. Ellen Giarelli, an associate professor in Drexel's College of Nursing and Health Professions, with Dr. Marcia Gardner.

Early intervention of biologic therapies improves outcome for Crohn's disease

A large-scale study of medical claims data shows that introducing sophisticated biologic therapies early in the course of treatment for Crohn's disease improves response to medication and reduces the need for surgery.

Kaposi's sarcoma-associated herpesvirus senses and reacts to host cell's impending death

A research team led by Children's National Medical Center has identified a trigger that causes latent Kaposi's sarcoma-associated herpesvirus (KSHV) to rapidly replicate itself. KSHV causes Kaposi's sarcoma, primary effusion lymphoma, and other cancers that commonly affect immunocompromised patients, including those with AIDS.

Caffeine increases eye's ability to produce tears

Researchers at the University of Tokyo's School of Medicine have shown for the first time that caffeine intake can significantly increase the eye's ability to produce tears, a finding that could improve treatment of dry eye syndrome. This common eye condition affects about four million people age 50 and older in the United States.

Allied Healthcare announces Coridon license to vector technology

Allied Healthcare Group (ASX: AHZ) has announced an update on the progress of Coridon, its investment company founded by Professor Ian Frazer and working on developing the next generation of vaccines. Included in these activities, Cordon has entered into a license agreement with Nature Technology Corporation (NTC) and has contracted VGXI Inc. in the US for production of clinical material for the Phase I study scheduled to begin later this year.

Tumor microenvironment contributes critically to drug response

It should be possible to significantly improve the response of common cancers to existing "classical" chemotherapy drugs, say scientists at Cold Spring Harbor Laboratory (CSHL), by introducing agents that alter the interaction of cancer cells with their immediate surroundings, called the tumor microenvironment.

Individuals with low-quality genes may produce offspring with even more inferior chromosomes

Evolutionary biologists at the University of Toronto have found that individuals with low-quality genes may produce offspring with even more inferior chromosomes, possibly leading to the extinction of certain species over generations.

Genetically modified mosquitoes offer hope of malaria eradication amid growing drug resistance

"In recent weeks, the emergence on the Thai-Myanmar border of malaria strains resistant to artemisinin, a plant-derived drug, have led to pessimistic headlines and reminders of the setback caused by resistance to the drug chloroquine, which began in the 1950s," columnist and author Matt Ridley writes in the Wall Street Journal's "Mind & Matter," noting, "April 25 is World Malaria Day, designed to draw attention to the planet's biggest infectious killer."

Study finds lower cytokine levels in the plasma of children with autism

A University of Kansas Medical Center study found significantly lower levels of several cytokines, the immune system's messengers and regulators, in the plasma of children with autism disorder (AD) compared to that of unrelated healthy siblings from other families who had members with autism spectrum disorders.

UCSF scientists assemble high-value genetic resource to help researchers

One of the ultimate ways of understanding what impact any particular gene has in human health or disease is to disrupt it-knocking it down or wiping it out in a worm, fly or mouse and gauging what happens next. Now scientists at the University of California, San Francisco (UCSF) Diabetes Center and the Gladstone Institute for Cardiovascular Disease have assembled a large publicly available resource to help researchers determine the importance of genes in mice and better gauge what roles they might play in disease.

Researchers identify 56 genetic variants that influence BMD

Researchers at The Institute for Aging Research at Hebrew SeniorLife, an affiliate of Harvard Medical School, have co-authored the largest meta-analysis of genome-wide association studies of osteoporosis as part of an international consortium and have identified dozens of genetic variants found to be linked to an increased risk of developing osteoporosis and of suffering broken bones.

Study pinpoints compounds that repress cancer gene’s activity

A research team pursuing one of the most commonly altered genes in cancer has laid a critical foundation for understanding this gene that could point the way toward developing drugs against it. A recent study of cancer genetics pointed to the gene MCL1, which encodes a protein that helps keep cells alive

32 genetic variations could play a role in osteoporosis risk

A team of international researchers have found 32 new genetic regions linked to fractures and osteoporosis. According to the new study published in the April 15 online edition of Nature Genetics, changes in these regions could offer protection from, or greater risk for, bone-weakening disease.
