Elderly people with hardening of arteries are more likely to have beta-amyloid plaques in brain

Even for elderly people with no signs of dementia, those with hardening of the arteries are more likely to also have the beta-amyloid plaques in the brain that are a hallmark of Alzheimer's disease, according to a study published in the October 16, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Spraying plant hormone on broccoli may boost cancer-fighting potential

Spraying a plant hormone on broccoli - already one of the planet's most nutritious foods - boosts its cancer-fighting potential, and researchers say they have new insights on how that works.

Scientists identify 127 mutated genes that appear to drive development of tumors in the body

Examining 12 major types of cancer, scientists at Washington University School of Medicine in St. Louis have identified 127 repeatedly mutated genes that appear to drive the development and progression of a range of tumors in the body. The discovery sets the stage for devising new diagnostic tools and more personalized cancer treatments.

Research in mouse whiskers reveals signal pathway from touch neuron to brain

Human fingertips have several types of sensory neurons that are responsible for relaying touch signals to the central nervous system. Scientists have long believed these neurons followed a linear path to the brain with a "labeled-lines" structure.

Researchers discover why women with BRCA gene develop breast and ovarian cancer

Researchers announced today in the journal Lancet Oncology that they are well on the way to discovering why women with the faulty genes BRCA 1 and BRCA 2, one of which was inherited by the actress Angelina Jolie, develop breast and ovarian cancer rather than other cancers.

Research findings point the way to new class of antibiotics for skin and heart infections

Researchers at NYU Langone Medical Center have discovered a new mechanism by which the deadly Staphylococcus aureus bacteria attack and kill off immune cells. Their findings, published today in the journal Cell Host & Microbe, explain a critical survival tactic of a pathogen that causes more skin and heart infections than any other microbe, and kills more than 100,000 Americans every year.

Discovery of neural firing-rate set point opens door to possible treatment for devastating disorders

As we learn and develop, our neurons change. They make new pathways and connections as our brain processes new information. In order to do this, individual neurons use an internal gauge to maintain a delicate balance that keeps our brains from becoming too excitable.

Light pulses stimulate designer peptides to trigger death pathway in cancerous cells

Researchers at Cardiff University have created a peptide (a small piece of protein), linked to a light-responsive dye, capable of switching 'on' death pathways in cancer cells. The peptide remains inactive until exposed to external light pulses which convert it into a cell death signal.

Trovagene launches pharmaceutical alliance to monitor lung cancer patients' EGFR mutational status

Trovagene, Inc., a developer of cell-free molecular diagnostics, today announced that it will collaborate with a pharmaceutical company to evaluate Trovagene's proprietary, urine-based, cell-free DNA technology for the detection of certain epidermal growth factor receptor mutations associated with lung cancer.

CU researchers explore why maximum heart rate decreases with age

Researchers at the University of Colorado have new insight into the age-old question of why maximum heart rate decreases with age. This decrease in maxHR not only limits the performance of aging athletes but it is also a leading cause for nursing home admittance for otherwise-healthy elderly individuals who no longer have the physical capacity required for independent living.

Study aims to identify age-related changes in metabolic pathways

Have you ever wondered why young children can eat bags of Halloween candy and feel fine the next day - compared to adults who experience all sorts of agony following the same junk food binge? Evolution and a gene called Foxo may be to blame. Working in fruit flies, scientists at the Buck Institute have identified a mechanism that helps the flies adapt to changes in diet when they're young; they've discovered that same mechanism gets misregulated as the flies age, disrupting metabolic homeostasis, or balance.

Simple memory test can have noticeable impact on how old some older adults feel

You're only as old as you feel, or so the saying goes. Now, research suggests that a simple memory test can have a noticeable impact on just how old some older adults feel, aging them about five years in the span of five minutes. The findings are published in Psychological Science, a journal of the Association for Psychological Science.

Locomotion of C. elegans worm to make big difference in biomedical research

One might wonder why researchers would even care about the nuances of the one-millimeter long nematode worm, let alone take the time to study them. But the answer is simple: they can provide powerful insights into human health and disease.

Genetics professor turns accidental discovery into a way to study TBI

Faced with news of suicides and brain damage in former professional football players, geneticist Barry Ganetzky bemoaned the lack of model systems for studying the insidious and often delayed consequences linked to head injuries.

Findings shed light on the role of environmental event in development of neural circuits in newborns

Neurons that process sensory information such as touch and vision are arranged in precise, well-characterized maps that are crucial for translating perception into understanding. A study published by Cell Press on October 14 in the journal Developmental Cell reveals that the actual act of birth in mice causes a reduction in a brain chemical called serotonin in the newborn mice, triggering sensory maps to form.

Research shows inhibition of Rcan1 protein may reduce atherosclerosis in mice

Researchers of the Spanish research council (Consejo Superior de Investigaciones Cient-ficas, CSIC) and the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have discovered that inhibiting the protein Rcan1 in mice reduces the burden of atherosclerosis, one of the commonest cardiovascular diseases.

New discovery may lead to effective treatments for chronic itching

Anyone who has suffered through sleepless nights due to uncontrollable itching knows that not all itching is the same. New research at Washington University School of Medicine in St. Louis explains why.

Ghrelin hormone released during chronic stress may predispose people to PTSD

About a dozen years ago, scientists discovered that a hormone called ghrelin enhances appetite. Dubbed the "hunger hormone," ghrelin was quickly targeted by drug companies seeking treatments for obesity - none of which have yet panned out.
