Roadmap to areas of the brain associated with affective aggression

A North Carolina State University researcher has created a roadmap to areas of the brain associated with affective aggression in mice. This roadmap may be the first step toward finding therapies for humans suffering from affective aggression disorders that lead to impulsive violent acts.

Regular Fanconi anemia cells aren't sensitive to resveratrol

Fanconi anemia is a recessive genetic disorder affecting 1 in 350,000 babies, which leaves cells unable to repair damaged DNA. This lack of repair puts Fanconi anemia patients at high risk for developing a variety of cancers, especially leukemias and head and neck cancer.

Drugs targeting protein TGF-β may be used to treat ovarian cancer

In the September issue of the Journal of Clinical Investigation, researchers at MD Anderson Cancer Center report that ovarian cancer cells activate the HOXA9 gene to compel stromal cells to create an environment that supports tumor growth.

Scientists identify master regulator essential for progression and relapse of deadly brain cancer

A*STAR scientists have identified a biomarker of the most lethal form of brain tumours in adults- glioblastoma multiforme. The scientists found that by targeting this biomarker and depleting it with a potential drug, they were able to prevent the progression and relapse of the brain tumour.

Green tea chemical found to boost memory

It has long been believed that drinking green tea is good for the memory. Now researchers have discovered how the chemical properties of China’s favorite drink affect the generation of brain cells, providing benefits for memory and spatial learning. The research is published in Molecular Nutrition & Food Research.

Scientists discover new anti-cancer and anti-metastatic molecule

A new molecule with anti-cancer and anti-metastatic properties has been discovered by teams from CNRS, CEA, the Institut Curie and Inserm, in collaboration with Australian and British researchers.

A-kinase anchoring proteins influence levels of glucose in the body

Scientists from the United States and Sweden have discovered a new control point that could be important as a drug target for the treatment of diabetes and other metabolic diseases.

Converting blood cells to a stem cell state: an interview with Elias Zambidis, M.D., Ph.D.

The primitive stem cell state we created is called an “induced pluripotent stem cell” (iPSC). iPSC are a new, unique, and artificially-created type of stem cell that were first described in 2006 by a Japanese scientist named Shinya Yamanaka.

Morphological changes occur rapidly in response to cardiac injury

Cardiac injury leads to significant structural changes in the heart, including enlargement, excess formation of fibrous growth tissue, and abnormalities of the coronary vasculature. While associated factors have been targeted for therapeutic intervention, the results have been conflicting. Most studies have investigated these changes after six days of injury. However, advanced stages of remodeling have already begun by day seven following injury.

Whole-genome sequencing can track origin and movement of TB pathogens

Reconstructing the spread of killer diseases such as tuberculosis (TB) from person to person using DNA sequencing quickly identifies the origin and movement of pathogens. This approach is directly informing public health strategies to control infectious disease outbreaks, says a scientist speaking at the Society for General Microbiology's Autumn Conference at the University of Warwick.

Posterior medial cortex more specifically engaged in recall or imagination

You already know it's hard to balance your checkbook while simultaneously reflecting on your past. Now, investigators at the Stanford University School of Medicine - having done the equivalent of wire-tapping a hard-to-reach region of the brain - can tell us how this impasse arises.

Study finds sex differences in vision between men and women

The way that the visual centers of men and women's brains works is different, finds new research published in BioMed Central's open access journal Biology of Sex Differences. Men have greater sensitivity to fine detail and rapidly moving stimuli, but women are better at discriminating between colors.

People with normal blood sugar range may be at increased risk of brain shrinkage

People whose blood sugar is on the high end of the normal range may be at greater risk of brain shrinkage that occurs with aging and diseases such as dementia, according to new research published in the September 4, 2012, print issue of Neurology-, the medical journal of the American Academy of Neurology.

PRISM technique as accurate as ELISAs in identifying proteins within biological samples

Combining two well-established analytic techniques and adding a twist identifies proteins from blood with as much accuracy and sensitivity as the antibody-based tests used clinically, researchers report this week in Proceedings of the National Academy of Sciences Early Edition online.

Scientists succeed in clarifying molecular signature of hantaviruses

Scientists at Charité - Universitätsmedizin Berlin and Labor Berlin GmbH have succeeded in clarifying the molecular signature of the viruses that lead to an increasing size and number of hantavirus outbreaks in Germany.

Gene therapy approach restores ability to smell in mouse model of congenital anosmia

Scientists funded by the National Institutes of Health have restored the ability to smell in a mouse model of a human genetic disorder that causes congenital anosmia-the inability to smell from birth. The approach uses gene therapy to regrow cilia, cell structures that are essential for olfactory function.

Heavy alcohol use rewires brain circuitry and increases risk of PTSD

Doctors have long recognized a link between alcoholism and anxiety disorders such as post-traumatic stress disorder (PTSD). Those who drink heavily are at increased risk for traumatic events like car accidents and domestic violence, but that only partially explains the connection. New research using mice reveals heavy alcohol use actually rewires brain circuitry, making it harder for alcoholics to recover psychologically following a traumatic experience.

Metabolic syndrome associated with cognitive and brain impairments in adolescents

A new study by researchers at NYU School of Medicine reveals for the first time that metabolic syndrome (MetS) is associated with cognitive and brain impairments in adolescents and calls for pediatricians to take this into account when considering the early treatment of childhood obesity.

Missing link between bone marrow stem cells and human immune system

UCLA researchers have discovered a type of cell that is the "missing link" between bone marrow stem cells and all the cells of the human immune system, a finding that will lead to a greater understanding of how a healthy immune system is produced and how disease can lead to poor immune function.

MDA7 compound shows promise against Alzheimer's disease

A compound developed to treat neuropathic pain has shown potential as an innovative treatment for Alzheimer's disease, according to a study by researchers at Cleveland Clinic's Lerner Research Institute and Anesthesiology Institute.
