Tranylcypromine may also hold promise in treating sickle cell disease

An antidepressant drug used since the 1960s may also hold promise for treating sickle cell disease, according to a surprising new finding made in mice and human red blood cells by a team from the University of Michigan Medical School.

New study reveals how control of brain blood flow develops with age

A new study by Columbia Engineering researchers finds that the infant brain does not control its blood flow in the same way as the adult brain. The paper, which the scientists say could change the way researchers study brain development in infants and children, is published in the February 18 Early Online edition of Proceedings of the National Academy of Sciences (PNAS).

Data from Eleven Biotherapeutics' EBI-005 preclinical study on ocular diseases

Eleven Biotherapeutics, a biopharmaceutical company creating novel and differentiated protein-based biotherapeutics, has published preclinical data in Proceedings of the National Academy of Sciences (PNAS) showing beneficial effects of EBI-005, the first rationally-designed topically administered IL-1 protein for the treatment of ocular diseases.

Cholesterol metabolism regulated by bacteria in the small intestine

Researchers at the Sahlgrenska Academy, University of Gothenburg, Sweden, show that cholesterol metabolism is regulated by bacteria in the small intestine. These findings may be important for the development of new drugs for cardiovascular disease.

FSH, LH two important hormones that regulate puberty and maturation processes

FSH and LH are two important hormones which regulate the processes of puberty and maturation. These hormones are secreted by the pituitary gland and are transported in the blood to the genitalia, where they regulate maturation.

Researchers design molecules that can stop colon cancer progression

A Basque research consortium has managed to halt the progress of colon cancer and its metastasis in the liver in an experimental model with mice. This advance, that may open a new path for the future treatment of such pathologies, has been achieved by creating molecules which interfere with the adhesion of tumour cells to other cells of the organism. In this way, the molecules halt both the growth of the tumour and the dissemination of the tumour to and its proliferation in other organs.

Study describes pharmacological action of TZDs directly on pancreas

A scientific study published on the journal Diabetes, edited by the American Diabetes Association, describes for the first time the pharmacological action of thiazolidinediones (TZDs) —anti-diabetic drugs— directly on pancreas, the organ which produces insulin.

New lab at Diamond to help scientists delve into inner workings of pathogens

The UK's national synchrotron facility, Diamond Light Source, is now the first and only place in Europe where pathogens requiring Containment Level 3 - including serious viruses such as those responsible for AIDS, Hepatitis and some types of flu - can be analysed at atomic and molecular level using synchrotron light.

Article details mechanism by which long non-coding RNA-activators promote gene expression

Long segments of RNA- encoded in our DNA but not translated into protein-are key to physically manipulating DNA in order to activate certain genes, say researchers at The Wistar Institute. These non-coding RNA-activators (ncRNA-a) have a crucial role in turning genes on and off during early embryonic development, researchers say, and have also been connected with diseases, including some cancers, in adults.

Scientists discover new subgroups of GC patients with different disease's characteristics

A collaboration between Portuguese and Italian scientists has discovered new subgroups of stomach cancer patients with different disease's characteristics, an information that is hoped will help improving the clinical management of a disease that still kills a dismaying 3 out of 4 patients.

New frontiers in trauma and stroke recovery

Cynthia Thompson, a world-renowned researcher on stroke and brain damage, will discuss her groundbreaking research on aphasia and the neurolinguistic systems it affects Feb. 16 at the annual meeting of the American Association for the Advancement of Science (AAAS). An estimated one million Americans suffer from aphasia, affecting their ability to understand and/or produce spoken and/or written language.

Researchers explore cellular signals produced by the body in response to traumatic injury

When it comes to healing the terrible wounds of war, success may hinge on the first blood clot - the one that begins forming on the battlefield right after an injury. Researchers exploring the complex stream of cellular signals produced by the body in response to a traumatic injury believe the initial response - formation of a blood clot - may control subsequent healing.

Aerobic exercise can increase brain size and improve cognition in children, older adults

Exercise doesn't only strengthen your heart and muscles - it also beefs up your brain. Dozens of studies now show that aerobic exercise can increase the size of critical brain structures and improve cognition in children and older adults.

Study paves way for new prosthetics that connect directly to the nervous system

For an amputee, replacing a missing limb with a functional prosthetic can alleviate physical or emotional distress and mean a return of vocational ability or cosmetics. Studies show, however, that up to 50 percent of hand amputees still do not use their prosthesis regularly due to less than ideal functionality, appearance, and controllability. But Silvestro Micera, of the -cole Polytechnique F-d-rale de Lausanne (EPFL) in Switzerland, is paving the way for new, smart prosthetics that connect directly to the nervous system.

Research reveals how quickly the Achilles tendon can regenerate

The Achilles heel of the body - getting over damage to tendons can be a long and painful process. By combining the nuclear tests of the 1950s with tissue samples and modern technology, a research collaboration between the Aarhus University and University of Copenhagen now reveals why the healing process is so slow.
