Immunity: A secret to making macrophages 2013-07-24

By California Institute of Technology

Biologists have worked out the details of a mechanism that leads undifferentiated blood stem cells to become macrophages -- immune cells that attack bacteria and other foreign pathogens. The process involves an unexpected cycle in which cell division slow

Multiple sclerosis research could help repair damage affecting nerves 2013-07-24

By University of Edinburgh

Multiple sclerosis treatments that repair damage to the brain could be developed thanks to new research. A study has shed light on how cells are able to regenerate protective sheaths around nerve fibers in the brain.

BPA and chlorine means bad news: Modified forms of bisphenol A found to alter hormone signaling in new, disturbing ways 2013-07-24

By University of Texas Medical Branch at Galveston

The ubiquity of the endocrine-disrupting chemical bisphenol A led researchers to ask what it might be doing in publicly supplied, chlorinated drinking water. The answer: Chlorinated BPA has different, but no less profound effects on cell-signaling network

Here's yet another reason to get off the couch: new research findings suggest that regularly breaking a sweat may lower the risk of having a stroke.

Pediatric anesthetic risk: Ketamine may damage children's learning ability and memory 2013-07-24

By Neural Regeneration Research

Recent studies have found that anesthesia drugs have neurotoxicity on the developing neurons, causing learning and memory disorders and behavioral abnormalities. Ketamine is commonly used in pediatric anesthesia. A clinical retrospective study found that

It's not just the heat, it's the ozone: Hidden heat wave dangers exposed 2013-07-24

By University of York

During heat waves – when ozone production rises as plants’ ozone absorption is curtailed -- more pollution is left in the air. This resulted in the loss of an estimated 460 lives in the UK in the hot summer of 2006.

Nano drug crosses blood-brain tumor barrier, targets brain-tumor cells and blood vessels 2013-07-24

By Ohio State University Medical Center

The blood-brain barrier protects the brain from poisons but also prevents drugs from reaching brain tumors. A preclinical study shows that an experimental nanotechnology drug called SapC-DOPS crosses the tumor blood-brain barrier, targets brain-tumor cell

Cheaper anti-cancer drug as effective as expensive drug in treating most common cause of blindness in older adults 2013-07-24

By Queen's University, Belfast

An anti-cancer drug has been proven to be equally as effective in treating the most common cause of blindness in older adults as a more expensive drug specifically formulated for this purpose.

High blood pressure patients: Non-adherence to medication greatly increases risk of fatal and non-fatal strokes 2013-07-24

By European Society of Cardiology (ESC)

People with high blood pressure, who don’t take their anti-hypertensive drug treatments when they should, have a greatly increased risk of suffering a stroke and dying from it compared to those who take their medication correctly.

Potential for MERS coronavirus to spread internationally 2013-07-24

By St. Michael's Hospital

The life-threatening MERS coronavirus that has emerged in the Middle East could spread faster and wider during two international mass gatherings involving millions of people in the next few months, according to researchers who describe the most likely pat

Chromosomal abnormalities may explain increased cancer risk in type 2 diabetes 2013-07-24

By Centre national de la recherche scientifique (CNRS)

Certain chromosomal abnormalities of the preleukemic type appear to be over-represented in patients with type 2 diabetes (T2D) who are suffering from vascular complications. This finding may provide a partial explanation for the higher rates of cancer-rel

Early detection and treatment of Alzheimer's disease prevents psychological and behavioural symptoms 2013-07-24

By University of Eastern Finland

Persons with Alzheimer's disease are able to manage their everyday activities longer and they suffer from less psychological and behavioral symptoms if the diagnosis is made and treatment begun at a very early phase of the disease, indicates a recent stud

By BMJ-British Medical Journal

There has been a "worrying" increase in alcohol related deaths among young women in England and Scotland, since the middle of the last decade, finds new research.

Deadliest cancers may respond to new drug treatment strategy 2013-07-24

By University of California, San Francisco (UCSF)

Researchers have found a way to knock down cancers caused by a tumor-driving protein called “myc,” paving the way for patients with myc-driven cancers to enroll in clinical trials for experimental treatments. 

Alternative target for breast cancer drugs 2013-07-24

By EMBO - excellence in life sciences

Scientists have identified higher levels of a receptor protein found on the surface of human breast tumor cells that may serve as a new drug target for the treatment of breast cancer. The results show that elevated levels of the protein Ret, which is shor

Molecular switch controls the destiny of self-eating cells 2013-07-24

By Karolinska Institutet

Researchers have discovered a previously unknown mechanism that controls whether a cell survives autophagy, a process that can be compared to the cell consuming parts of itself. The discovery means that it might now be possible to influence the process, w

Microbes can influence evolution of their hosts 2013-07-24

By Vanderbilt University

Contrary to current scientific understanding, it appears that our microbial companions play an important role in their hosts' evolution. A new study provides the first direct evidence that these microbes can contribute to the origin of new species by redu

New approach to protecting prion protein from altering shape, becoming infectious 2013-07-24

By Case Western Reserve University

Scientists have identified a mechanism that can prevent the normal prion protein from changing its molecular shape into the abnormal form responsible for neurodegenerative diseases.

Targeting malaria: Engineered liver tissue could help scientists test new drugs and vaccines 2013-07-24

By Massachusetts Institute of Technology

A team of researchers has now developed a way to grow liver tissue that can support the liver stage of the life cycle of the two most common species of malaria, Plasmodium falciparum and Plasmodium vivax.
