Researchers identify mechanism linked to brain damage

Researchers have discovered a mechanism linked to the brain damage often suffered by stroke victims--and are now searching for drugs to block it.

Proper copper levels essential to health of the brain at rest, new study finds

In recent years it has been established that copper plays an essential role in the health of the human brain. Improper copper oxidation has been linked to several neurological disorders including Alzheimer's, Parkinson's, Menkes' and Wilson's.

Researchers find unusual role of lactate in metabolism of alveolar soft part sarcoma

Researchers from Huntsman Cancer Institute at the University of Utah discovered the unusual role of lactate in the metabolism of alveolar soft part sarcoma (ASPS), a rare, aggressive cancer that primarily affects adolescents and young adults. The study also confirmed that a fusion gene is the cancer-causing agent in this disease.

Study reveals how one type of DNA damage may lead to several human diseases

Using a new imaging technique, National Institutes of Health researchers have found that the biological machinery that builds DNA can insert molecules into the DNA strand that are damaged as a result of environmental exposures. These damaged molecules trigger cell death that produces some human diseases, according to the researchers.

Study sheds light on how animals regulate body size

The proper regulation of body size is of fundamental importance, but the mechanisms that stop growth are still unclear. In a study now published in the scientific journal eLife, a research group from Instituto Gulbenkian de Ciência (IGC), led by Christen Mirth, shed new light on how animals regulate body size.

Researchers reveal how cancer cells succeed at entrapping genetic program of growth inhibition

Healthy cells reduce their growth when there is a lack of oxygen (hypoxia). This makes it even more surprising that hypoxia is a characteristic feature of malignant tumours. In two publications in the current edition of the "Nature Communications" journal, researchers from Goethe University and Justus-Liebig-University of Giessen report on how cancer cells succeed at circumventing the genetic program of growth inhibition.

People with sleep apnea have lower peak oxygen uptake during aerobic activity

People with moderate to severe obstructive sleep apnea may have an intrinsic inability to burn high amounts of oxygen during strenuous aerobic exercise, according to a new study led by researchers at University of California, San Diego School of Medicine.

2014 Canadian Prix Galien for Innovative Product Award presented to Esbriet (pirfenidone)

This year's prestigious Canadian Prix Galien for Innovative Product Award has been presented to Esbriet (pirfenidone), a medicine used to treat idiopathic pulmonary fibrosis (IPF). It is the only medication approved in Canada with a specific IPF indication and is approved for mild to moderate IPF in adults.

New app directly connects single ventricle heart defect patients to doctors

A powerful new app is directly connecting single ventricle heart defect patients to their doctors, dramatically improving their monitoring while they recover from heart surgery at home. Girish Shirali, MBBS, FACC, FASE, Co-Director of the Ward Family Heart Center at Children's Mercy Kansas City, will report today on how the technology is changing patient care at the American Heart Association Scientific Sessions 2014.

FIRS mobilizes members to raise awareness on COPD

On World COPD Day (19 November 2014), the Forum of International Respiratory Societies (FIRS) is mobilizing its members to raise awareness of the disease and help prevent the risk factors that cause it.

Excess fat in lungs may cause pulmonary fibrosis

Pulmonary fibrosis has no cure. It's caused by scarring that seems to feed on itself, with the tougher, less elastic tissue replacing the ever moving and stretching lung, making it increasingly difficult for patients to breathe.

Blocking key brain receptor cell could neutralize biological consequences of Alzheimer's

Blocking a key receptor in brain cells that is used by oxygen free radicals could play a major role in neutralizing the biological consequences of Alzheimer's disease, according to researchers at Temple University.

New nanoparticles can simultaneously perform MRI and fluorescent imaging in living animals

MIT chemists have developed new nanoparticles that can simultaneously perform magnetic resonance imaging (MRI) and fluorescent imaging in living animals. Such particles could help scientists to track specific molecules produced in the body, monitor a tumor's environment, or determine whether drugs have successfully reached their targets.

Research breakthrough offers hope for patients with severe spinal cord injuries

Case Western Reserve researchers have developed a procedure that restores function to muscles involved in the control of breathing - even when they have been paralyzed for more than a year. The breakthrough offers hope that one day patients with severe spinal cord injuries will be able to breathe again without the assistance of a ventilator.

Study shows how phthalates linked with complications of pregnancy

In recent years, scientists have linked chemicals known as phthalates with complications of pregnancy and fetal development.

Drug combination shows promise in patients with newly diagnosed multiple myeloma

The investigational drug ixazomib taken orally in combination with lenalidomide and dexamethasone shows promise in patients with newly diagnosed multiple myeloma, according to the results of a phase 1/2 study published in the journal Lancet Oncology.

Chaetocin synergistic with TKIs against CML cells

Chaetocin, a mycotoxin that increases oxidative stress, can complement the activity of tyrosine kinase inhibitors in chronic myeloid leukaemia by overcoming innate resistance mediated by secreted bone marrow stromal cytokines and growth factors, researchers report.
