Introducing maspin protein into tumor nucleus can stop growth and spread of cancer

According to the Canadian Cancer Society, one in four Canadians will die of cancer. This year alone, the disease will kill an estimated 75,000 people. With incidence rates on the rise, more cancer patients are facing grave prognoses.

Scientist discovers novel way to convert human skin cells into neurons

A scientist at the Gladstone Institutes has discovered a novel way to convert human skin cells into brain cells, advancing medicine and human health by offering new hope for regenerative medicine and personalized drug discovery and development.

Oral chicken interferon-alpha may significantly reduce influenza infection

Avian influenza virus is a threat to the commercial chicken industry and, with its recent rapid spread across China, has also shown the ability for transmission from chickens to humans and other mammals.

New protein 3D model could inhibit cancer development

Researchers at the University of Hertfordshire have developed a new structural model of a protein, which makes it possible to develop more effective drugs to target diseases such as cancer, heart disease and influenza.

Drug to prevent brain ageing: Study

A new study shows that some chemicals given to rhesus macaques blocked a brain molecule that slows the firing of the brain's nerve cells, or neurons, as they age—prompting those nerve cells to act young again.

New candidate gene for human benign childhood epilepsies

A new epilepsy gene, LGI2, has been found in the Lagotto Romagnolo dogs, known from their gift for truffle hunting. The gene discovery made by Professor Hannes Lohi and his research group at the University of Helsinki and the Folkhälsan Rsearch Center offers a new candidate gene for human benign childhood epilepsies characterized by seizure remission.

New approaches to improve biomarker discovery

An article in the current edition of Chemical & Engineering News, ACS's weekly newsmagazine, describes the trials, tribulations, and triumphs of one of the hottest pursuits in modern biomedical science - the search for "biomarkers" that could greatly improve the diagnosis of disease and efforts to monitor the effectiveness of treatment.

Cigarette smoke exposure alters airway tissue in people with COPD

Cigarette smoke exposure fundamentally alters airway tissue from people with chronic obstructive pulmonary disease (COPD) at the cellular level, laying the groundwork for airway thickening and even precipitating precancerous changes in cell proliferation that may be self-perpetuating long after cigarette smoke exposure ends, according to Australian researchers.

SMRT DNA sequencing technology reveals genetic profile of German E. coli bacteria

An international team of scientists has successfully employed single molecule, real-time DNA sequencing technology from Pacific Biosciences of California, Inc. to provide valuable insights into the pathogenicity and evolutionary origins of the highly virulent bacterium responsible for the German E. coli outbreak.

Roux-en-Y gastric bypass appears to reduce dietary fat intake

Roux-en-Y gastric bypass, the most common type of bariatric surgery in the United States, is currently considered the most effective therapy for morbid obesity.

Engineers work to design prosthetic arm that allows amputees to feel what they touch

Engineering researchers at four U.S. universities are embarking on a four-year project to design a prosthetic arm that amputees can control directly with their brains and that will allow them to feel what they touch.

Mitochondrial genome undergoes random reorganisation during reprogramming

Induced pluripotent stem cells (iPS cells) are truly talented multi-taskers. They can reproduce almost all cell types and thus offer great hope in the fight against diseases like Alzheimer's and Parkinson's. However, it would appear that their use is not entirely without risk: during the reprogramming of body cells into iPS cells, disease-causing mutations can creep into the genetic material.

Scientists show how RET gene in breast cancer cells responds to estrogen

Using human breast cancer cells and the protein that causes fireflies to glow, a Johns Hopkins team has shed light on why some breast cancer cells become resistant to the anticancer effects of the drug tamoxifen. The key is a discovery of two genetic "dimmer switches" that apparently control how a breast cancer gene responds to the female hormone estrogen.

Reprogrammed kidney cells could make transplants and dialysis things of the past

Approximately 60 million people across the globe have chronic kidney disease (CKD), and many will need dialysis or a transplant. Breakthrough research published in the Journal of the American Society Nephrology indicates that patients' own kidney cells can be gathered and reprogrammed.

Researchers identify gene linked to Lesch-Nyhan disease

In humans, inherited mutations in a gene called HPRT1 lead to very specific self-destructive behavior. Boys with Lesch-Nyhan disease experience uncontrollable urges to bite their fingers, slam their arms into doorways and otherwise harm themselves.

Conference to discuss new discoveries in cognitive neuroscience research

New discoveries in the field of cognitive neuroscience hold great promise for improving current teaching methods. Yet there is a significant gap between such scientific discoveries and the application of this knowledge in the classroom.

UM researchers unravel genomic code of German E. coli bacteria

A team led by University of Maryland School of Medicine Institute for Genome Sciences researchers has unraveled the genomic code of the E. coli bacteria that caused the ongoing deadly outbreak in Germany that began in May 2011.

New research shows unique nature of human brain aging

Brains shrink in humans, potentially causing a number of health problems and mental illnesses as people age, but do they shrink to the same extent in the closest living relatives to humans--the chimpanzees? New research says no, making the extreme amount of brain shrinkage resulting from normal aging in humans unique.

Noninvasive brain computer interface could turn thoughts into motion

"Brain cap" technology being developed at the University of Maryland allows users to turn their thoughts into motion. Associate Professor of Kinesiology José 'Pepe' L. Contreras-Vidal and his team have created a non-invasive, sensor-lined cap with neural interface software that soon could be used to control computers, robotic prosthetic limbs, motorized wheelchairs and even digital avatars.

Roux-en-Y gastric bypass surgery can lead to effective weight loss

Imperial College London. The findings, published in the American Journal of Physiology—Regulatory, Integrative, and Comparative Physiology, suggest a new mechanism by which some types of bariatric surgery lead to long-term weight loss.
