Cancer medicine component could prevent heart attacks

A substance in medicines for cancer and epilepsy could also prevent heart attacks, according to researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, who have been using it to stimulate the body's own defence system against blood clots.

TLRs contribute to brain damage following hypoxia in newborns

Two out of every thousand babies are at risk of brain damage in connection with birth. Researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, have identified mechanisms behind these injuries, which could lead to better treatment and a richer life for the infants affected.

UCF researchers use stem cells to create nerve-muscle junctions

University of Central Florida researchers, for the first time, have used stem cells to grow neuromuscular junctions between human muscle cells and human spinal cord cells, the key connectors used by the brain to communicate and control muscles in the body.

Mutations that affect lysosomes play a role in causing persistent stuttering

Researchers at Washington University School of Medicine in St. Louis have obtained new evidence that at least some persistent stuttering is caused by mutations in a gene governing not speech, but a metabolic pathway involved in recycling old cell parts.

Study reveals principal mechanism of action for paracetamol

Researchers at King's College London have discovered how one of the most common household painkillers works, which could pave the way for less harmful pain relief medications to be developed in the future.

New procedure could be adapted for use with X-ray techniques in studying human health

For more than a century, the use of X-rays has been a prime diagnostic tool when it comes to human health. As it turns out, X-rays also are a crucial component for studying and understanding molecules, and a new approach -- just published by researchers at the University of Georgia -- may dramatically improve what researchers can learn using the technique.

GPS at WUSTL now offers new cancer genetic test

Physicians can now take advantage of a new genetics test -- one of the first of its kind to be offered in the United States -- that can help determine the best treatment for cancer patients.

Scientists identify atypical metabolic pathway unique to some tumors

A research team led by UT Southwestern Medical Center scientists has identified an atypical metabolic pathway unique to some tumors, possibly providing a future target for drugs that could reduce or halt the spread of cancer.

Dendritic cells play a novel protective role in pancreas

NYU Langone Medical Center researchers have discovered the novel protective role dendritic cells play in the pancreas. The new study, published in the November issue of journal Gastroenterology, shows dendritic cells can safeguard the pancreas against acute pancreatitis, a sudden dangerous swelling and inflammation of the pancreas gland.

Scientists identify P-Rex1 protein key to movement of melanoblasts

Researchers from UNC Lineberger Comprehensive Cancer Center are part of a team that has identified a protein, called P-Rex1, that is key to the movement of cells called melanoblasts. When these cells experience uncontrolled growth, melanoma develops.

Bioengineering delivers innovative solutions to diagnose and repair TBI

Bioengineering -- the application of engineering principles to understand and treat medical conditions -- is delivering innovative solutions for diagnosing and repairing damage to the brain caused by a traumatic injury.

Researchers pinpoint cancer-fighting potential in bat plant

In a new study published this month in the Journal of the American Chemical Society, researchers with The University of Texas Health Science Center at San Antonio have pinpointed the cancer-fighting potential in the bat plant, or Tacca chantrieri.

EpiGen to collaborate with Nestl- Research Center in Switzerland

The EpiGen Consortium, an international alliance of the world's leading epigenetics researchers (Singapore Institute for Clinical Sciences of the Agency for Science, Technology and Research (A*STAR), National University of Singapore, University of Southampton, Medical Research Council - Lifecourse Epidemiology Unit, AgResearch Limited, Auckland UniServices Limited) are pleased to announce the creation of a research collaboration with Nestl- Research Center in Switzerland.

Biochemists identify structure of hydroxyurea that specifically inhibits proteasome

As the "recycling plant" of the cell, the proteasome regulates vitally important functions. When it is inhibited, the cell chokes on its own waste. Cancer cells, in particular, are very sensitive because they need the proteasome for their uncontrolled growth. Biochemists at the Technische Universitaet Muenchen (TUM) have now identified the lead structure of a new class of drugs that attacks the proteasome in an unusual way. New medication could be developed on the basis of this previously unknown binding mechanism.

Arginine may reactivate T-cells in patients with glioblastoma

In many cases, tumors suppress a patient's immune system in a way that keeps the cancer safe from immune system attack. This is particularly true for patients with glioblastoma, a primary brain tumor that carries a prognosis of only 12-15 months survival after diagnosis.

Researchers discover molecular sensor that detects wound-induced hydrogen peroxide

Hydrogen peroxide isn't just that bottled colorless liquid in the back of the medicine cabinet that's used occasionally for cleaning scraped knees and cut fingers. It's also a natural chemical in the body that rallies at wound sites, jump-starting immune cells into a series of events. A burst of hydrogen peroxide causes neutrophils, the immune system's first responders, to rush to the wound to fight microorganisms, remove damaged tissue and then start the inflammation process.

New way to exploit expression of BRAF by papillary carcinomas for therapeutic purposes

Papillary carcinoma is the most common form of thyroid cancer. Approximately one quarter of these carcinomas have mutations in the BRAF gene. The prevalence of such mutations is even greater in high-grade carcinomas, particularly those that are refractory to standard treatment, which is radioactive iodine.

Scientists identify new immune system defect in aged mice

As people age, their immune system becomes less robust. This makes them more susceptible to serious and frequently life-threatening infections with viruses that affect the respiratory tract such as influenza A virus.
