Epigenetic factor likely plays a key role in fueling most common childhood cancer 2013-06-20

By St. Jude Children's Research Hospital

Changes in an epigenetic mechanism that turns expression of genes on and off may be as important as genetic alterations in causing pediatric acute lymphoblastic leukemia, according to a new study.

Frequent soccer ball 'heading' may lead to brain injury 2013-06-20

By Albert Einstein College of Medicine of Yeshiva University

Researchers have shown that soccer players who frequently head the ball have brain abnormalities resembling those found in patients with concussion (mild traumatic brain injury). The study used advanced imaging techniques and cognitive tests that assessed

Blueprint for blood vessel fusion discovered 2013-06-20

By University of Basel

The fusion of blood vessels during the formation of the vascular system follows a uniform process. In this process, the blood vessels involved go through different phases of a common choreography, in which the splitting and the rearrangement of endothelia

Pendulum swings back on 350-year-old mathematical mystery 2013-06-20

By University of Pittsburgh

A 350-year-old mathematical mystery could lead toward a better understanding of medical conditions like epilepsy or even the behavior of predator-prey systems in the wild, researchers report.

Cardiac MRI use reduces adverse events for patients with acute chest pain 2013-06-20

By Wake Forest Baptist Medical Center

Doctors have found that using stress cardiac magnetic resonance (CMR) imaging in an Emergency Department observation unit to care for patients with acute chest pain is a win-win – for the patient and the institution.

Shape of nanoparticles points the way toward more targeted drugs 2013-06-20

By Sanford-Burnham Medical Research Institute

The shape of nanoparticles can enhance drug targeting, according to new research. The study found that rod-shaped nanoparticles -- or nanorods -- as opposed to spherical nanoparticles, appear to adhere more effectively to the surface of endothelial cells

U.S. Doctors' Group Labels Obesity a Disease 2013-06-20

By Steven Reinberg

Advocates say AMA's move will boost resources to fight weight-gain epidemic, but others question decision

Mapping the brain: Researchers use signals from natural movements to identify brain regions 2013-06-17

By Albert-Ludwigs-Universität Freiburg

Whether we run to catch a bus or reach for a pen: Activities that involve the use of muscles are related to very specific areas in the brain. Traditionally, their exact location has only been determined through electrical stimulation or unnatural, experim

Two biomarkers predict increased risk for 'silent' strokes 2013-06-17

By Methodist Hospital, Houston

Two biomarkers being investigated as predictors of heart and vascular disease appear to indicate risk for "silent" strokes and other causes of mild brain damage that present no symptoms, report researchers.

Innate immunity: When DNA is out of place 2013-06-17

By Ludwig-Maximilians-Universitaet Muenchen (LMU)

In animal cells, DNA molecules are normally restricted to the cell nucleus and the mitochondria. When DNA appears outside these organelles – in the so-called cytosol - it most probably originates from a bacterial pathogen or a DNA virus. This is

Scientists coax brain to regenerate cells lost in Huntington's disease in mouse model 2013-06-17

By University of Rochester Medical Center

Researchers have been able to mobilize the brain's native stem cells to replenish a type of neuron lost in Huntington's disease. The scientists were able to both trigger the production of new neurons in mice with the disease and show that the new cells su

Fukushima-derived radioactivity in seafood poses minimal poses minimal health risk, experts say 2013-06-17

By Stony Brook University

In 2012, biologists reported that they had detected radioactivity in Pacific bluefin tuna swimming off the California coast. The source of the radioactivity was Japan's Fukushima Dai-ichi powerplants, which were damaged by the strong earthquake and subseq

Tumors disable immune cells by using up sugar 2013-06-17

By Washington University in St. Louis

Cancer cells’ appetite for sugar may have serious consequences for immune cell function, researchers at Washington University School of Medicine in St. Louis have learned.

Genetic mutation inherited from father's side linked to early puberty 2013-06-17

By Brigham and Women's Hospital

Researchers have identified that a genetic mutation leads to a type of premature puberty, known as central precocious puberty.

Weather conditions do not affect fibromyalgia pain or fatigue 2013-06-17

By Wiley

Weather conditions including temperature, sunshine, and precipitation have no impact on fibromyalgia symptoms in female patients, study suggests. Results suggest, however, that individual patients may be sensitive to some changes in the weather.

Multiple sclerosis: Phase 1 trial safely resets patients' immune systems, reduces attack on myelin protein 2013-06-17

By Northwestern University

A phase 1 clinical trial for the first treatment to reset the immune system of multiple sclerosis (MS) patients showed the therapy was safe and dramatically reduced patients' immune systems' reactivity to myelin by 50 to 75 percent. The therapy used billi

Obese mums may pass health risks on to grandchildren 2013-06-17

By University of Edinburgh

Health problems linked to obesity -- like heart disease and diabetes -- could skip an entire generation, a new study suggests.

Nutrition during first 1,000 days of life crucial for childhood and economic development 2013-06-17

By Johns Hopkins Bloomberg School of Public Health

New research on maternal and childhood nutrition finds that over 3 million children die every year of malnutrition -— accounting for nearly half of all child deaths under 5. Along with state-of-the-art global estimates on the long-term burden of

Manipulating memory in the hippocampus 2013-06-17

By American Friends of Tel Aviv University

Scientists have discovered that manipulating the levels of the protein tomosyn in a part of the brain associated with learning and memory may aid in the development of therapeutic procedures for epilepsy and neurodegenerative diseases such as Alzheimer's.

New gene that is essential for nuclear reprogramming 2013-06-17

By Centro Nacional de Investigaciones Oncologicas (CNIO)

Researchers are still fascinated by the idea of reprogramming the cells of any tissue, turning them into cells with the capacity to differentiate into cells of a completely different type -- pluripotent cells -- and they are still striving to understand h
