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.

Powerful link between circadian rhythms and metabolism

The discovery of a major gear in the biological clock that tells the body when to sleep and metabolize food may lead to new drugs to treat sleep problems and metabolic disorders, including diabetes.

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.

Methylphenidate may help induce recovery from propofol anesthesia

The ability of the commonly used stimulant methylphenidate (Ritalin) to speed recovery from general anesthesia appears to apply both to the inhaled gas isoflurane, as previously reported, and to the intravenous drug propofol. Members of the same Massachusetts General Hospital (MGH) research team that reported the isoflurane study are publishing similar results for propofol in the May issue of Anesthesiology, and their paper has been issued online.

Measuring executive functions may predict 'game intelligence' in soccer players

Measuring what are known as executive functions, which reflect the cognitive ability to deal with sudden problems, may make it possible to predict how good an elite soccer player will become in the future. This has been shown by a new study from Karolinska Institutet in Sweden. Scientists believe for the first time that they have found the scientific key to what has previously been described as 'game intelligence' in successful soccer players.

ACMG Foundation, Genzyme announce recipients of Medical Genetics Training Award

Carlos E. Prada, MD of Cincinnati Children's Hospital and James D. Weisfeld-Adams, MD of Mount Sinai School of Medicine, NY were honored as the 2012-2013 recipients of the Genzyme/ACMG Foundation Medical Genetics Training Award in Clinical Biochemical Genetics at the ACMG 2012 Annual Clinical Genetics Meeting in Charlotte, NC.

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.

Researchers generate endodermal progenitor cells for future diabetes treatments

Researchers have generated a new type of human stem cell that can develop into numerous types of specialized cells, including functioning pancreatic beta cells that produce insulin. Called endodermal progenitor (EP) cells, the new cells show two important advantages over embryonic stem cells and induced pluripotent stem cells: they do not form tumors when transplanted into animals, and they can form functional pancreatic beta cells in the laboratory.

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.

Novel technology to grow new primordial lung progenitors

Researchers at Boston University School of Medicine (BUSM) and Boston Medical Center (BMC) have derived a population of pure lung and thyroid progenitor cells in vitro that successfully mimic the developmental milestones of lung and thyroid tissue formation.

Three genes within human embryonic stem cells regulate development

Yale researchers show in detail how three genes within human embryonic stem cells regulate development, a finding that increases understanding of how to grow these cells for therapeutic purposes.

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.

Researchers develop new technique to grow stem cells

Post-doctoral researcher David Fluri and Professor Peter Zandstra at the University of Toronto's Institute of Biomaterials and Biomedical Engineering (IBBME) have developed a unique new technique for growing stem cells that may make possible cost-effective, large-scale stem cell manufacturing and research.

African American women more likely to have ER-negative breast cancer

American women of African ancestry are more likely than European Americans to have estrogen-receptor-negative (ER-negative) breast cancer. There continues to be discussion about the role of low levels of vitamin D in the development of breast cancer for these women.

Collaborative Cross project to develop lab mice with increased genetic diversity

With a 95 percent genomic similarity to humans, mice have long been used to learn about the genetic causes of human disease. Once researchers can shine a light on the genetic factors that cause disease in mice, they can start to develop prevention and treatment options to protect the human population.

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.

Towards a drug to control cystic fibrosis

Harvard stem cell researchers at Massachusetts General Hospital (MGH) have taken a critical step in making possible the discovery in the relatively near future of a drug to control cystic fibrosis (CF), a fatal lung disease that claims about 500 lives each year, with 1,000 new cases diagnosed annually.

Ameritox, Ridge Diagnostics partner to develop MDDScore test

Ridge Diagnostics, Inc., a neurodiagnostic company, announced today it has entered into an exclusive agreement with Ameritox, Ltd., a leader in medication monitoring, for the license rights to its proprietary developmental blood test MDDScore, a multiple biomarker analysis for Major Depressive Disorder (MDD) for primary care and pain physicians.

Gold nanostars can deliver drug directly to cancer cell nucleus

Nanotechnology offers powerful new possibilities for targeted cancer therapies, but the design challenges are many. Northwestern University scientists now are the first to develop a simple but specialized nanoparticle that can deliver a drug directly to a cancer cell's nucleus -- an important feature for effective treatment.

New microfluidics-based microarray can accurately detect breast cancer

One in eight women will be diagnosed with breast cancer during her lifetime. The earlier cancer is detected, the better the chance of successful treatment and long-term survival. However, early cancer diagnosis is still challenging as testing by mammography remains cumbersome, costly, and in many cases, cancer can only be detected at an advanced stage.
