Higher-fit children have more compact white-matter tracts in the brain than lower-fit peers

A new study of 9- and 10-year-olds finds that those who are more aerobically fit have more fibrous and compact white-matter tracts in the brain than their peers who are less fit. "White matter" describes the bundles of axons that carry nerve signals from one brain region to another. More compact white matter is associated with faster and more efficient nerve activity.

Researchers identify microRNAs that differentiate male and female fruit flies

Men and women differ in plenty of obvious ways, and scientists have long known that genetic differences buried deep within our DNA underlie these distinctions. In the past, most research has focused on understanding how the genes that encode proteins act as sex determinants.

Researchers develop new technique to map pulse pressure and elasticity of arteries in the brain

Researchers at the Beckman Institute at the University of Illinois at Urbana-Champaign have developed a new technique that can noninvasively image the pulse pressure and elasticity of the arteries of the brain, revealing correlations between arterial health and aging.

University of Kansas researcher earns grant to study role of dietary supplement in muscle growth

A University of Kansas professor has been chosen to take part in a grant project that will test the role of a dietary supplement in muscle growth for everyone from athletes to the elderly and has also been named educator of the year by the granting agency.

Researchers uncover role of epigenetic changes in Alzheimer's disease

A team led by researchers at the University of Exeter Medical School and King's College London has uncovered some of the strongest evidence yet that epigenetic changes in the brain play a role in Alzheimer's disease.

Natural killer cells can be used to combat acute lymphoblastic leukemia

Researchers at Children's Hospital Los Angeles have shown that a select team of immune-system cells from patients with leukemia can be multiplied in the lab, creating an army of natural killer cells that can be used to destroy the cancer cells.

Study shows bryostatin plays key role in slowing or reversing Alzheimer's disease

Neurotrope, Inc. (OTCQB: NTRP) today announced that results from a new study, entitled, "PKCe Deficits in Alzheimer's Disease Brains and Skin Fibroblasts," published in the recent edition of the peer-reviewed Journal of Alzheimer's Disease and co-authored by Tapan K. Khan, Ph.D.; Abhik Sen, Ph.D.; Jarin Hongpaisan, Ph.D.; Chol S. Lim, Ph.D.; Thomas J. Nelson, Ph.D., and; Dr. Daniel L. Alkon, each of the Blanchette Rockefeller Neurosciences Institute (BRNI), provide further indication of the role that protein kinase C epsilon (PKCe) may play in the potential treatment of Alzheimer's disease (AD).

Study confirms close link between immune system and adult neurogenesis

A new study by Barbara Beltz, the Allene Lummis Russell Professor of Neuroscience at Wellesley College, and Irene Soderhall of Uppsala University, Sweden, published in the August 11 issue of the journal Developmental Cell, demonstrates that the immune system can produce cells with stem cell properties, using crayfish as a model system. These cells can, in turn, create neurons in the adult animal.

BGRF scientists propose Oncofinder method for accurate analysis of gene expression data

Scientists from the Biogerontology Research Foundation (BGRF), a UK-based charity founded to support ageing research and address the challenges of a rapidly ageing population, propose a new concept for signalome-wide analysis of changes in intracellular pathways, called OncoFinder, which allows for accurate and robust cross-platform analysis of gene expression data.

NASA study reveals how spaceflight affects immune system of crew members

There is nothing like a head cold to make us feel a little dazed. We get things like colds and the flu because of changes in our immune system. Researchers have a good idea what causes immune system changes on Earth-think stress, inadequate sleep and improper nutrition.

Research findings call for clinical testing of relevant drugs to prevent NASH

Non-alcoholic fatty liver disease (NAFLD) is a common affliction, affecting almost 30 percent of Americans, with a significant number suffering from its most severe form, called non-alcoholic steatohepatitis or NASH, which can lead to cirrhosis and liver cancer. In recent years, NASH has become the leading cause of liver transplantation.

Targeting club cells may help shorten duration of flu symptoms

A specialized subset of lung cells can shake flu infection, yet they remain stamped with an inflammatory gene signature that wreaks havoc in the lung, according to a study published in The Journal of Experimental Medicine.

New research finds that early use of antibiotics can alter immunity later on

New University of British Columbia research found that receiving antibiotic treatments early in life can increase susceptibility to specific diseases later on.

FGF proteins play broad roles in wound healing

Mice missing two important proteins of the vascular system develop normally and appear healthy in adulthood, as long as they don't become injured. If they do, their wounds don't heal properly, a new study shows.

Innate lymphoid cells induce specific T and B cell responses during inflammation

In case of an inflammation the body releases substances that increase the immune defense. During chronic inflammation, this immune response gets out of control and can induce organ damage.

MGH-developed microfluidic device may help study key steps involved in development of tumor metastasis

A microfluidic device developed at Massachusetts General Hospital may help study key steps in the process by which cancer cells break off from a primary tumor to invade other tissues and form metastases.

Researchers use microengineered device to show how EMT cancer cells migrate

Using a microengineered device that acts as an obstacle course for cells, researchers have shed new light on a cellular metamorphosis thought to play a role in tumor cell invasion throughout the body.

Rare mutation in suspect gene disrupts brain circuitry in complex psychiatric disorders

Researchers have long suspected that major mental disorders are genetically-rooted diseases of synapses - the connections between neurons.

Study to explain how brain reorganizes itself as children learn math facts

As children learn basic arithmetic, they gradually switch from solving problems by counting on their fingers to pulling facts from memory. The shift comes more easily for some kids than for others, but no one knows why.

Individual’s genetic make-up determines effect of stress on emotional centres

Our individual genetic make-up determines the effect that stress has on our emotional centres. These are the findings of a group of researchers from the MedUni Vienna. Not every individual reacts in the same way to life events that produce the same degree of stress.
