Computer model shows how cancerous tumors manipulate blood-vessel growth for their own benefit

Rice University researchers have built a simulation to show how cancerous tumors manipulate blood-vessel growth for their own benefit.

New portable system can produce life-saving NO from air by means of electrical spark

Treatment with inhaled nitric oxide (NO) has proven to be life saving in newborns, children and adults with several dangerous conditions, but the availability of the treatment has been limited by the size, weight and complexity of equipment needed to administer the gas and the therapy's high price.

Extra set of guanines in DNA may function like 'spare' to help prevent cancers from developing

Carrying around a spare tire is a good thing -- you never know when you'll get a flat. Turns out we're all carrying around "spare tires" in our genomes, too. Today, in ACS Central Science, researchers report that an extra set of guanines (or "G"s) in our DNA may function just like a "spare" to help prevent many cancers from developing.

Researchers unravel mechanisms that enable accumulation of tumour promoting protease in stressed cancer cells

A mechanism beyond the level of gene regulation, which is often the underlying reason for changes in protein levels, does enable the strong accumulation of a tumour promoting protease in stressed cancer cells. The group of BIOSS researcher Prof. Dr. Thomas Reinheckel teamed up with BIOSS investigator Prof. Dr. Sabine Rospert and their colleagues from the University Medical Center Freiburg, Prof. Dr. Elmar Stickeler and Dr. Peter Bronsert, in order to unravel mechanisms by which stress-resistant production of cancer promoting proteins occurs.

Discovery reveals possibility of using water for finer analysis of the brain's functioning

To observe the brain in action, scientists and physicians use imaging techniques, among which functional magnetic resonance imaging (fMRI) is the best known. These techniques are not based on direct observations of electric impulses from activated neurons, but on one of their consequences. Indeed, this stimulation triggers physiological modifications in the activated cerebral region, changes that become visible by imaging.

Researchers analyze cardiometabolic benefits of exercise

Everyone knows that exercise generally helps the cardiovascular system, but much remains unknown about how the benefits arise, and what to expect in different people who exercise to improve their health. To gain a more precise understanding of how exercise improves health and whom it helps most, researchers analyzed the results of 160 randomized clinical trials with nearly 7,500 participants.

Scientists identify new protein that affects growth of secondary breast tumours in the brain

Scientists from the University of Leeds and The Institute of Cancer Research, London, have discovered a new protein which triggers the growth of blood vessels in breast cancer tumours which have spread to the brain, a common location which breast cancer can spread to.

Study explores effects of patent foramen ovale in high-altitude Bolivian setting

A common heart feature long thought to have negligible effects on human health and performance may be problematic at high altitude, according to University of Oregon researchers.

Three National Laureates selected for 2015 Blavatnik National Awards for Young Scientists

A chemist who has made important discoveries in both the human brain and sustainable energy, a neurosurgeon who has done pioneering work mapping the "blueprint" of how humans speak and hear, and a computer scientist who has changed our understanding of the capacity of wireless networks are the three winners of the 2015 Blavatnik National Awards for Young Scientists.

Researchers identify specific calcium channel that plays crucial role in healthy sleep

Sleep seems simple enough, a state of rest and restoration that almost every vertebrate creature must enter regularly in order to survive. But the brain responds differently to stimuli when asleep than when awake, and it is not clear what brain changes happen during sleep.

Newcastle University scientists document action spectrum of ultraviolet damage in skin cells

Scientists at Newcastle University have documented for the first time the DNA damage which can occur to skin across the full range of ultraviolet radiation from the sun providing an invaluable tool for sun-protection and the manufacturers of sunscreen.

Symptoms and characteristics of cluster headache

June is National Migraine and Headache Awareness Month. The global burden of headache is extremely large, putting headache among the top 10 causes of disability worldwide.

Study: Cellular respiration separates effects of bactericidal and bacteriostatic antibiotics

Antibiotics are the mainstay in the treatment of bacterial infections, and together with vaccines, have enabled the near eradication of infectious diseases like tuberculosis, at least in developed countries.

Johns Hopkins scientists use experimental therapy to reverse progression of atherosclerosis in rodents

In what may be a major leap forward in the quest for new treatments of the most common form of cardiovascular disease, scientists at Johns Hopkins report they have found a way to halt and reverse the progression of atherosclerosis in rodents by loading microscopic nanoparticles with a chemical that restores the animals’ ability to properly handle cholesterol.

EEG-measurements better predict outcome of postanoxic coma

EEG-measurements enable better prediction of the outcome of a coma that was caused by a lack of oxygen to the brain. This became clear from research of the University of Twente (MIRA) in cooperation with Rijnstate hospital and Medisch Spectrum Twente.

New 'smart insulin patch' could help patients suffering from diabetes

Painful insulin injections could become a thing of the past for the millions of Americans who suffer from diabetes, thanks to a new invention from researchers at the University of North Carolina and NC State, who have created the first "smart insulin patch" that can detect increases in blood sugar levels and secrete doses of insulin into the bloodstream whenever needed.

UT Southwestern scientists devise new technique to identify cell that replenishes adult heart muscle

Regenerative medicine researchers at UT Southwestern Medical Center have identified a cell that replenishes adult heart muscle by using a new cell lineage-tracing technique they devised.

Tackling fuel poverty can help reduce debilitating sickle cell disease, save significant money for NHS

Tackling fuel poverty in the homes of people with sickle cell disease could reduce debilitating attacks and save significant money for the NHS, according to a study by Sheffield Hallam University funded by the Chesshire Lehmann Fund.

Scientists forecast an average 'dead zone' in Gulf of Mexico this year

Scientists are expecting that this year's Gulf of Mexico hypoxic zone, also called the "dead zone," will be approximately 5,483 square miles or about the size of Connecticut-the same as it has averaged over the last several years.

Researchers explore the science of exosomes in heart repair

A little more than a decade ago, researchers discovered that all cells secrete tiny communications modules jammed with an entire work crew of messages for other cells. Today, a team of researchers, led by stem cell researcher Raj Kishore, PhD, Director of the Stem Cell Therapy Program at the Center for Translational Medicine at Temple University School of Medicine, is harnessing the communications vesicles excreted by stem cells and using them to induce the damaged heart to repair itself.
