Researcher wins $1.9 million grant to find better way to manage combat-related injuries

Advances in battlefield trauma care, fueled by evidence-based research and practice, are saving lives in both combat and civilian settings.

Researchers show how rhythm of DNA replication can be manipulated to kill cancer cells

Human cells divide and create new cells throughout life. In this process, a steady – even rhythmic – supply of DNA building blocks is needed to create new DNA. Now researchers from the University of Copenhagen are the first to show exactly how human cells regulate this process so it does not fail and cause illness.

Low blood phosphate levels may pose danger to cardiovascular health

Low phosphate in the blood is linked to the risk of heart attack and coronary artery disease, a new study in the journal PLOS One reports.

Increasing hydroxyurea dose linked to reduction in hospitalization for young sickle cell anemia patients

St. Jude Children's Research Hospital investigators have shown that using the drug hydroxyurea to boost average fetal hemoglobin levels above 20 percent in children and teenagers with sickle cell anemia was associated with at least a two-fold reduction in hospitalization for any reason.

RUDN chemists obtain unusual organic compounds that could be used in pharmaceutics

Researchers from RUDN University conducted an effective three-component reaction, obtaining unusual organic compounds. The latter are structurally similar to a number of biologically active compounds - which makes it possible to use them in pharmaceutics.

Mushrooms have high amounts of antioxidants that may help with anti-aging treatments

Mushrooms may contain unusually high amounts of two antioxidants that some scientists suggest could help fight aging and bolster health, according to a team of Penn State researchers.

New pencil-like spectrometer holds promise for remote medical diagnostics

Spectral images, which contain more color information than is obtainable with a typical camera, reveal characteristics of tissue and other biological samples that can't be seen by the naked eye.

Researchers catch killer cells red-handed in the act of microbial murder

Immune cells called "killer cells" target bacteria invading the body's cells, but how do they do this so effectively? Bacteria can quickly evolve resistance against antibiotics, yet it seems they have not so readily been able to evade killer cells. This has caused researchers to become interested in finding out the exact mechanism that killer cells use to destroy bacterial invaders.

Anesthesiologists call for more research into pediatric deaths caused by dental anesthesia

Anesthesiologists call for more research into child deaths caused by dental anesthesia in an article published online by the journal Pediatrics.

Researchers use gold nanoshells to effectively release cancer drugs inside tumors

Researchers investigating ways to deliver high doses of cancer-killing drugs inside tumors have shown they can use a laser and light-activated gold nanoparticles to remotely trigger the release of approved cancer drugs inside cancer cells in laboratory cultures.

Early intervention may be crucial to successful treatment of Friedreich's ataxia

New research published today in Disease Models & Mechanisms indicates that early intervention should be a key target in the development of new therapeutics for Friedreich's ataxia, as current treatments may be administered too late to target the disease effectively.

Experts call for routine screening of babies across Europe for heart defects

All babies across Europe should be routinely screened for critical congenital heart defects (CCHD) within 24 hours of their birth, say a group of experts led by a University of Birmingham Professor and Honorary Consultant Neonatologist at Birmingham Women's Hospital.

Researchers find new way to restrict ability of cancer to use glucose for energy

Cancer cells consume exorbitant amounts of glucose, a key source of energy, and shutting down this glucose consumption has long been considered a logical therapeutic strategy.

Stem cells could help improve blood circulation in diabetic patients with peripheral artery disease

Stem cells taken from muscle tissue could promote better blood flow in patients with diabetes who develop peripheral artery disease, a painful complication that can require surgery or lead to amputation.

Research reveals impact of helpful strain of bacteria on infants’ digestive tract

Some of the first living things to greet a newborn baby do a lot more than coo or cuddle. In fact, they may actually help the little one's digestive system prepare for a lifetime of fighting off dangerous germs.

Study shows hemodynamic and metabolic changes up to 7 days after traumatic spinal cord injury

Researchers have shown that some of the critical pathophysiological responses to traumatic spinal cord injury (SCI), evidence of insufficient oxygen levels and metabolic stress that can permanently damage tissue, persist for at least a week post-injury at and extending away from the injury site in a large animal model.

Sickle cell patients suffer discrimination, poor care — and shorter lives

For more than a year, NeDina Brocks-Capla avoided one room in her large, brightly colored San Francisco house — the bathroom on the second floor.

Pre-menopausal women with advanced breast cancer unnecessarily excluded from clinical trials

Pre-menopausal women with the most common type of advanced breast cancer are usually excluded from medical research unnecessarily, according to an expert panel at the Advanced Breast Cancer Fourth International Consensus Conference.

DZHK studies to investigate non-invasive diagnosis of diastolic heart failure with the help of CMR

Two new studies on diastolic heart failure are starting at the German Centre for Cardiovascular Research. They will investigate whether this form of heart failure can be better diagnosed and its causes clarified with the help of cardiovascular magnetic resonance imaging.

Researchers identify neural circuitry responsible for rousing the brain during sleep apnea

A common and potentially serious sleep disorder, obstructive sleep apnea affects at least one-quarter of U.S. adults and is linked to increased risk of diabetes, obesity and cardiovascular disease. In a paper published today in the journal Neuron, researchers at Beth Israel Deaconess Medical Center identified specific neural circuitry responsible for rousing the brain of mice in simulated apnea conditions.
