Older adults experience problems in processing multisensory information

Much like trying to watch a video with the audio out of synch, older adults may have difficulty combining the stimuli they see and hear, and it could have implications for rapid decision-making tasks such as driving, according to new research.

New study may help understand how estrogens affect cognition and memory in women

A new study by University of Guelph researchers that narrows down where and how estrogens affect the brain may help in understanding how the hormones affect cognition and memory in women, says psychology professor Elena Choleris.

Molecular signatures can predict flu vaccine responses in young and old

What factors inhibit strong responses to seasonal flu vaccines in the elderly? Why do anti-flu antibodies last longer after vaccination in some people? Answers are emerging from an Emory University-based systems biology analysis of blood samples from more than 400 volunteers who received seasonal flu vaccines. Bali Pulendran, PhD, led a team of researchers who tracked patterns of gene expression, known as molecular signatures, of strong immune responses in volunteers' blood across five consecutive seasons from 2007 to 2011.

Cancer drug may protect kidneys from damage caused by chemotherapy agent cisplatin

A class of drugs used increasingly to help fight cancer may have the additional benefit of protecting the kidneys when packaged with the powerful chemotherapy agent cisplatin.

U of T researchers find another clue in understanding the cause of MS

Researchers at the University of Toronto have found another clue in understanding the cause of what drives Multiple Sclerosis (MS) disease. Their findings were published today in Immunity.

Innovative brain imaging study reveals why ToM deficiencies present in children with ASD

The holidays can be difficult for children with autism spectrum disorder (ASD), particularly because of new or different social situations. One reason scientists believe ASD causes impairment in social interactions is due to an inability to effectively infer other's thoughts and feelings through "theory of mind," or ToM -- the ability to understand the mental states of others and oneself.

UW-Madison scientist creates serotonin neurons from stem cells

Su-Chun Zhang, a pioneer in developing neurons from stem cells at the University of Wisconsin-Madison, has created a specialized nerve cell that makes serotonin, a signaling chemical with a broad role in the brain.

Columbia Engineering professor wins grant to study tendon-to-bone integration for rotator cuff repair

Helen H. Lu, professor of biomedical engineering at Columbia Engineering, has won a three-year $1.125 million Translational Research Award grant from the Department of Defense's Congressionally Directed Medical Research Programs for her research on tendon-to-bone integration for rotator cuff repair.

Can Nanostructured Microelectrodes be Used to Analyze Biomarkers? An Interview with Dr Shana Kelley

Electrochemical methods are appealing because simple and inexpensive instrumentation can be used to make highly sensitive measurements. However, it has been quite difficult to realize clinically-relevant levels of sensitivity using electrochemistry in highly complex, real-world samples.

Discovery could pave way for targeted therapies to treat penile cancer

Researchers have identified potential genetic alterations in penile cancer that could pave the way for targeted treatments.

VCU Massey Cancer Center scientists reveal signaling process that leads to excessive growth of cancer

The gene p53 has been described as the "guardian of the genome" due to its prominent role in preventing genetic mutations. More than half of all cancers are thought to originate from p53 mutations or loss of function, and now a recent study by VCU Massey Cancer Center scientist Richard Moran, Ph.D., explains why.

Gene variant linked to psychotic symptoms, cognitive impairment in people with bipolar disorder identified

Researchers at Karolinska Institutet, and the Sahlgrenska Academy at Gothenburg University in Sweden have identified a gene variant linked to psychotic symptoms and cognitive impairment in people with bipolar disorder. The study, which is published in the journal Molecular Psychiatry, describes a possible mechanism for how the gene variant produces clinical symptoms by affecting levels of specific proteins in the brain.

Researchers discover novel way to enhance, restore cancer suppressor activity in B-ALL

Researchers at Penn State College of Medicine, working with Chinese and American colleagues, have discovered a novel way to enhance and restore cancer suppressor activity in B-cell acute lymphoblastic leukemia, resulting in better outcomes in a pre-clinical model of the disease. The finding could pave the way for a new class of drugs for this and other forms of leukemia.

Liver protein aids in accelerating growth of insulin-producing pancreatic 'beta' cells

More than a quarter of the 30 million people with diabetes in the United States depend on daily injections of insulin to maintain their blood glucose levels in a healthy range. Scientists are investigating many techniques to help treat or potentially even cure many of these patients by increasing the body's own insulin-producing pancreatic "beta" cells.

Experimental drugs that modify cell metabolism also halt tumor growth

Experimental drugs that alter cell metabolism also halted tumor growth and extended survival in mice with cancers linked to changes in the same gene, according to a new study led by researchers at NYU Langone Medical Center, its Laura and Isaac Perlmutter Cancer Center and Massachusetts General Hospital.

New study describes a way to identify complex type of mutation in cancer genomes

New research shows that current approaches to genome analysis systematically miss detecting a certain type of complex mutation in cancer patients' tumors. Further, a significant percentage of these complex mutations are found in well-known cancer genes that could be targeted by existing drugs, potentially expanding the number of cancer patients who may benefit.

Researchers discover first broad spectrum drug that can potently kill aging cells in culture

Researchers from the University of Arkansas for Medical Sciences and other institutions are reporting the discovery of the first broad spectrum drug that can potently kill senescent (or aging) cells in culture and effectively clear the cells in animals by specifically targeting a pathway that is critical for the survival of senescent cells.

CAP2 gene responsible for cardiac conduction disease in mice

The presence or absence of the CAP2 gene causes sudden cardiac death in mice, according to new research from the Perelman School of Medicine at the University of Pennsylvania. In particular, the absence of the gene interrupts the animal's ability to send electrical signals to the heart to tell it to contract, a condition called cardiac conduction disease.

New study reveals link between tinnitus severity and emotion processing in the brain

Tinnitus, otherwise known as ringing in the ears, affects nearly one-third of adults over age 65. The condition can develop as part of age-related hearing loss or from a traumatic injury. In either case, the resulting persistent noise causes varying amounts of disruption to everyday life.

Study may help reduce sugar consumption, improve nutritional health of children

Everyone knows that children love sweets, but ever wonder why some kids seem to want more sugary food than others? It could be because they need more sugar to get that same sweet taste. According to new research from the Monell Center, sensitivity to sweet taste varies widely across school-aged children and is in part genetically-determined.
