Researchers identify novel approach to enhance tissue repair and organ regeneration

Because most human tissues do not regenerate spontaneously, advances in tissue repair and organ regeneration could benefit many patients with a wide variety of medical conditions.

Report suggests venom immunotherapy can make sufferers less allergic to insect stings

If you think summer insects are done setting their sights on ruining your outdoor gathering, think again. August's hot and dry climate is the perfect breeding ground for insects, especially yellow jackets. And for the millions of Americans allergic to insect stings, these late summer bugs can be deadly.

Scientists reveal biochemical pathway responsible for manufacturing glycoalkaloids

In 1924, Science magazine reported on a fatal case of potato poisoning: James B. Matheney of Vandalia, Illinois, had gathered about one and a half bushels of tubers, which had turned green due to sunlight exposure.

Scientists solve structure of infection tool used by Yersinia bacterium

Abdominal pain, fever, diarrhoea -- these symptoms could point to an infection with the bacterium Yersinia. The bacterium's pathogenic potential is based on a syringe-like injection apparatus called injectisome.

Montreal scientists develop novel approach for scanning entire genome

Recent technological developments in genomics have revealed a large number of genetic influences on common complex diseases, such as diabetes, asthma, cancer or schizophrenia. However, discovering a genetic variant predisposing to a disease is only a first step. To apply this knowledge towards prevention or cure, including tailoring treatment to the patient's genetic profile -also known as personalized medicine - we need to know how this genetic variant affects health.

Oxytocin hormone affects men and women differently, research finds

"The Love Hormone", Oxytocin affects men and women differently in social contexts- in men it improves the ability to identify competitive relationships whereas in women it facilitates the ability to identify kinship. "These findings are in agreement with previous studies on the social differences between the sexes: women tend to be more communal and familial in their behavior, whereas men are more inclined to be competitive and striving to improve their social status", said Prof. Simone Shamay-Tsoory from the Dept. of Psychology at the University of Haifa who led the research.

Naked mole rat: A fitting model for finding novel ways to fight cancer

Mice and rats have long since been a standard animal model for cancer research, mainly due to their short lifespan of four years on average and high incidence of cancer. Naked mole rats however, are a mystery among mammals. This social tiny African subterranean rodent has a maximum lifespan exceeding 30 years and most surprisingly, is cancer-resistant.

Transmembrane protein NG2 controls orientation of cell migration toward the wound

When the central nervous system is injured, oligodendrocyte precursor cells migrate to the lesion and synthesize new myelin sheaths on demyelinated axons. Scientists at the Institute of Molecular Cell Biology at Johannes Gutenberg University Mainz have now discovered that a distinct protein regulates the direction and movement of OPC toward the wound. The transmembrane protein NG2, which is expressed at the surface of OPCs and down-regulated as they mature to myelinating oligodendrocytes, plays an important role in the reaction of OPC to wounding.

New approach could provide alternative treatment for chemotherapy-resistant breast cancer

A new way to target a breast cancer cells' appetite for over-indulging in sugar, that could provide an alternative treatment for chemotherapy resistant breast cancer, is being developed by Breast Cancer Campaign scientists at the University of Southampton.

Finding could influence effectiveness of bone marrow transplants for late-stage leukemia

Eight years ago, two former Stanford University postdoctoral fellows, one of them still in California and the other at the Harvard Stem Cell Institute in Cambridge, began exchanging theories about why patients with leukemia stop producing healthy blood cells. What was it, they asked, that caused bone marrow to stop producing normal blood-producing cells?

Miniscule signaling molecule plays critical role in certain acute and chronic diseases

Scientists seeking to harness the healing power of a miniscule signaling molecule that plays a critical role in certain acute and chronic diseases have been awarded a Program Project Grant (PPG) of nearly $10 million by the National Heart, Lung and Blood Institute of the National Institutes of Health.

Novel protein could lead to development of new drugs to treat variety of cancers

In cancer research, discovering a new protein that plays a role in cancer is like finding a key and a treasure map: follow the clues and eventually there could be a big reward. At least that's the hope from a new study published in the journal Nature that discovered a novel protein called ceramide-1 phosphate transport protein (CPTP) -- a finding that could eventually lead to the development of new drugs to treat a variety of cancers and other conditions involving inflammation and thrombosis, or blood clotting.

Brain development delay throughout childhood and adolescence for people born with FASD

Medical researchers at the University of Alberta recently published findings showing that brain development is delayed throughout childhood and adolescence for people born with Fetal Alcohol Spectrum Disorder (FASD).

Reinnervate's Alvetex Scaffold system chosen for 3D osteocytic cell culture experiments in microgravity

Market leading 3D cell culture company Reinnervate Ltd today announced that its Alvetex®Scaffold system has been chosen by a group at Massachusetts General Hospital for the first ever 3D osteocytic cell culture experiments in microgravity.

Chemists develop new method for parallel protein analysis

Chemists at Johannes Gutenberg University Mainz (JGU) have developed a new method for parallel protein analysis that is, in principle, capable of identifying hundreds or even thousands of different proteins. It could be used to detect the presence of viruses and identify their type in tiny samples. At the same time, it is very cost-effective and quick.

Researchers identify stem cells in urine can be directed to become multiple cell types

Could harvesting stem cells for therapy one day be as simple as asking patients for a urine sample? Researchers at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine and colleagues have identified stem cells in urine that can be directed to become multiple cell types.

Study: Full Body Illusions can be accompanied by changes in body temperature

Researchers from the Center for Neuroprosthetics at the Swiss Federal Institute of Technology (EPFL), Switzerland, show that people can be "tricked" into feeling that an image of a human figure -- an "avatar" -- is their own body. The study is published in the open-access journal Frontiers in Behavioral Neuroscience.

CHOP researchers advance stem cell studies in childhood leukemia, Diamond Blackfan anemia

First produced only in the past decade, human induced pluripotent stem cells are capable of developing into many or even all human cell types. In new research, scientists reprogrammed skin cells from patients with rare blood disorders into iPSCs, highlighting the great promise of these cells in advancing understanding of those challenging diseases-and eventually in treating them.
