Cord blood stem cells can repair cardiac muscle after heart attack

At least 20 million people survive heart attacks and strokes every year, according to World Health Organisation estimates, but many have poor life expectancy and require continual costly clinical care. The use of patient's own stem cells may repair heart attacks, although their benefit may be limited due to scarce availability and ageing. The researchers have found heart muscle-like cells grown using stem cells from human umbilical cord blood could help repair heart muscle cells damaged by a heart attack.

Insight into how powerful anti-HIV antibody grabs hold of the virus

Researchers at The Scripps Research Institute have uncovered the surprising details of how a powerful anti-HIV antibody grabs hold of the virus. The findings, published in Science Express on October 13, 2011, highlight a major vulnerability of HIV and suggest a new target for vaccine development.

Potential new protein target for sickle cell disease

National Institutes of Health-funded scientists have corrected sickle cell disease in adult laboratory mice by activating production of a special blood component normally produced before, but not after, birth.

Researchers control itch without dulling morphine's pain-killing effects

Itching is one of the most prevalent side effects of powerful, pain-killing drugs like morphine, oxycodone and other opioids. The opiate-associated itch is so common that even women who get epidurals for labor pain often complain of itching. For many years, scientists have scratched their own heads about why drugs that so effectively suppress pain also induce itch.

Stopping necroptosis in keratinocytes prevents skin inflammation

The outer layer of the skin, called the epidermis, forms a critical physical and immunological wall that serves as the body's first line of defense against potentially harmful microorganisms. Most of the epidermis consists of cells called keratinocytes that build a mechanical barrier but also perform immune functions.

Study: miR-34b gene associated with aggressive form of melanoma

A certain microRNA gene, miR-34b, could be a useful biomarker in early diagnosis of the most lethal forms of melanoma, according to new research published by KGI Professor Animesh Ray and his research collaborators.

Limited decision-making ability of individual cells is bolstered in masses

Researchers from Johns Hopkins have quantified the number of possible decisions that an individual cell can make after receiving a cue from its environment, and surprisingly, it's only two.

New technique stimulates stem cells after liver transplant to prevent rejection

Johns Hopkins researchers have developed a way to stimulate a rat's stem cells after a liver transplant as a means of preventing rejection of the new organ without the need for lifelong immunosuppressant drugs.

Laser-based analysis method can detect optical pressure differences in blood cells

U.S. Naval Research Laboratory researchers Dr. Sean J. Hart, Dr. Colin G. Hebert and Mr. Alex Terray have developed a laser-based analysis method that can detect optical pressure differences between populations or classes of blood cells that does not rely on prior knowledge, antibodies, or fluorescent labels for discrimination.

New insights into how adenovirus triggers an immune response

A Loyola University Chicago Stritch School of Medicine study could lead to improved gene therapies for conditions such as heart disease and cancer as well as more effective vaccines for tuberculosis, malaria and other diseases.

Hospitalized patients with anemia may not always benefit from transfusion

University of Kentucky researchers, including lead author Samy Selim of the Division of Cardiovascular Medicine and the Saha Cardiovascular Research Center, have recently published a paper suggesting that transfusion may not always be the best treatment for hospitalized patients with anemia.

Study reveals new regulatory elements in human genome

An international research team led by Kerstin Lindblad-Toh at the Broad Institute, US and Uppsala University, Sweden has mapped and compared the genomes of 29 mammals. The findings, published in Nature, reveal millions of new regulatory elements in the human genome that in various ways govern how proteins are formed. The new knowledge is important for our understanding of how mutations in human genes give rise to diseases.

SFDA approves China Medical Technologies' colorectal cancer assay

China Medical Technologies, Inc., a leading China-based advanced in-vitro diagnostic company, today announced that China's State Food and Drug Administration has approved the Company's real-time PCR-based V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog assay as a companion diagnostic test for the use of a targeted drug for the treatment of colorectal cancer patients.

Autism Speaks announces 10 new research grants

Autism Speaks, the world's largest autism science and advocacy organization, today announced the awarding of 10 new research grants totaling $1,782,934 in funding over the next three years. The selected studies will evaluate the effectiveness of a broad array of promising behavioral and medical treatments for core symptoms and associated medical issues in children, adolescents, and adults with autism spectrum disorders.

Researchers identify age-dependent beta cell proliferation pathway

As a person ages, the ability of their beta cells to divide and make new beta cells declines. By the time children reach the age of 10 to 12 years, the ability of their insulin-producing cells to replicate greatly diminishes. If these cells, called beta cells, are destroyed-as they are in type 1 diabetes-treatment with the hormone insulin becomes essential to regulate blood glucose levels and get energy from food.

RAZCER (Rapid Astrazeneca and CARO Evaluation of Radio-modifiers) awards announced - five Canadians win

Five leading Canadian radiation oncologists receive RAZCER Awards of $22,727 each for novel studies of radiation-drug interactions that have the potential to either protect normal tissues or sensitize tumours, and thus to enhance the effectiveness of radiation therapy for cancer patients. A selection committee of members of the Canadian Association of Radiation Oncology (CARO) selected the 2011 recipients from among a field of 12 applicants. Astrazeneca provides the funds for the RAZCER Award as an educational grant.

USPTO issues patent to Rexahn's new anti-cancer arylisoquinolinamine compounds

Rexahn Pharmaceuticals, Inc., a clinical stage pharmaceutical company commercializing potential best in class oncology and CNS therapeutics, today announced that the United States Patent & Trademark Office has issued U.S. Patent No. 8,034,829 to Rexahn, entitled "5, 6, or 7-Substituted-3-(hetero) arylisoquinolinamine derivatives and therapeutic use thereof."

Viewpoints: Screening for prostate cancer, stem cell research and free coverage for Iowa lawmakers

As a practicing internist, I need all the help I can get in diagnosing the many diseases that threaten the life and well-being of my patients. So perhaps you'll understand why I'm angered by the reckless new recommendations from the U.S. Preventive Services Task Force (a panel of primary care experts) that I don't use the prostate-specific antigen to screen men older than 40 for prostate cancer.
