Improving prefrontal cortex activity could help autistic people regulate emotions

Tantrums, irritability, self-injury, depression, anxiety. These symptoms are associated with autism, but they're not considered core symptoms of the disorder. Researchers from the UNC School of Medicine are challenging this assertion. They have used functional MRI to show that - when it comes to the ability to regulate emotions - brain activity in autistic people is significantly different than brain activity in people without autism.

Researchers explore KRAS pathway to find potential target for treating lung cancer

Despite the promise of the gene KRAS as a target for treating lung cancer, finding effective therapies has been challenging. Now researchers are traveling down the pathway to find what makes KRAS cancerous.

Developmental salivary biomarkers linked to feeding success in newborns

Results from a study published online in the Journal of Pediatrics hold the potential to substantially improve clinical decision-making to determine when a premature newborn is ready for oral feeding. The study describes developmental salivary biomarkers associated with feeding success in newborns, markers that could lead to development of objective assessment tools for caregivers.

Ghrelin hormone supplement increases sexual activity in mice

Swedish studies show that mice that receive a supplement of the "appetite hormone" ghrelin increase their sexual activity. Whether the hormone has the same impact on humans is unknown - but if it does, the researchers may have found the key to future treatments for sex abuse.

Research explores effect of DBS treatments in animals with brain injuries

The research, published in Behavioural Brain Research, was conducted by Pilar Segura and Ignacio Morgado (coordinators), Laura Aldavert and Marc Ramoneda, psychobiologists of the Institute of Neurosciences and the Department of Psychobiology and Health Sciences Methodology of the UAB and by Elisabet Kadar and Gemma Huguet, molecular biologists of the University of Girona, to explore the power of Deep Brain Stimulation treatments in the hypothalamus to recover the ability to learn and remember after a severe lesion of the amygdala.

TSRI scientists find drug candidates that can prevent degeneration of brain cells in Parkinson's

In a pair of related studies, scientists from the Florida campus of The Scripps Research Institute have shown their drug candidates can target biological pathways involved in the destruction of brain cells in Parkinson's disease.

Androgen receptor in prostate cancer cells can activate different gene set when bound to antiandrogens

The androgen receptor in prostate cancer cells can activate different sets of genes depending on whether it binds with an androgen hormone or an antiandrogen drug, according to a new study led by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

Researchers devise novel way to generate corneal stem cells for treating corneal blindness

Researchers in the Cedars-Sinai Board of Governors Regenerative Medicine Institute have devised a novel way to generate transplantable corneal stem cells that may eventually benefit patients suffering from life-altering forms of blindness.

Study links lysosomal dysfunction with neonatal intestinal disorders

Neonatal intestinal disorders that prevent infants from getting the nutrients they need may be caused by defects in the lysosomal system that occur before weaning, according to a new Northwestern Medicine study.

Sanford-Burnham researchers use human pluripotent stem cells to grow new hair

In a new study from Sanford-Burnham Medical Research Institute, researchers have used human pluripotent stem cells to generate new hair. The study represents the first step toward the development of a cell-based treatment for people with hair loss. In the United States alone, more than 40 million men and 21 million women are affected by hair loss.

Georgia Tech researchers unveil new version of genome annotation system

Georgia Tech researchers, working with colleagues in the National Center for Biotechnology Information, have released a new version of a genome annotation system capable of analyzing more than 2,000 prokaryotic genomes per day, helping researchers accelerate prokaryotic genomics-based studies worldwide.

Listeria poses pregnancy risk

A gut bacterium called Listeria (Listeria monocytogenes), which is often found in soft cheese, is known to present a risk to pregnant women. Listeria uses distinct tactics to breach the intestine and the placenta, using a protein called phosphoinositide-3 kinase (PI3-K), according to a study published in The Journal of Experimental Medicine.

Case Western researchers awarded NSF grant to develop new method to reduce risk of Ebola virus

Health care workers must diagnose and isolate Ebola victims at an early stage to have a chance to save them and prevent the virus from spreading. But the most sensitive and quickest diagnostic test produces a small percentage of false negative results that undermine efforts to control the deadly agent.

UNC researchers discover how two genes interact to trigger worst form of ovarian cancer

In the battle against ovarian cancer, UNC School of Medicine researchers have created the first mouse model of the worst form of the disease and found a potential route to better treatments and much-needed diagnostic screens.

New study may lead to novel drug target for treating lung cancer

A new study by University of Kentucky Markey Cancer Center researchers suggests that targeting a key enzyme and its associated metabolic programming may lead to novel drug development to treat lung cancer.

Penn scientists explore potential therapeutic target for cerebral cavernous malformations

Tens of millions of people around the world have abnormal, leak-prone sproutings of blood vessels in the brain called cerebral cavernous malformations (CCMs). These abnormal growths can lead to seizures, strokes, hemorrhages, and other serious conditions, yet their precise molecular cause has never been determined.

CHLA researchers develop new protein-based therapy against drug-resistant leukemia cells

Resistance of leukemia cells to contemporary chemotherapy is one of the most formidable obstacles to treating acute lymphoblastic leukemia (ALL), the most common form of childhood cancer. Now researchers at Children's Hospital Los Angeles have designed and developed a new protein-based therapy they believe will prove highly effective against drug-resistant leukemia cells.
