Century old rule of chemistry overturned - major implications for drug delivery

A new study by research chemists at the University of Warwick has challenged a century old rule of pharmacology that defined how quickly key chemicals can pass across cell walls. The new observations of the Warwick researchers suggest that the real transport rates could be up to a hundred times slower than predicted by the century old "Overton's Rule". This could have major implications for the development and testing of many future drugs.

Researchers find Leishmaniasis parasites evade death by exploiting the immune response to sand fly bites

Cutaneous leishmaniasis, a disease characterized by painful skin ulcers, occurs when the parasite Leishmania major, or a related species, is transmitted to a mammalian host by the bite of an infected sand fly.

Researchers show how new chemotherapy drugs kill cancerous tumors

Dr Stephen Taylor and Karen Gascoigne at the University of Manchester's Faculty of Life Sciences have taken a new systematic approach to studying anti-mitotic drugs, which are used extensively for breast or ovarian cancer in the UK.

Discovery of vital key to cancer

University of Manchester scientists have uncovered the 3D structure of Mps1 - a protein that regulates the number of chromosomes during cell division and thus has an essential role in the prevention of cancer - which will lead to the design of safer and more effective therapies.

Scientists develop ultra-sensitive optical protein sensor, a first for a salivary diagnostic test

For people who dislike needles, medical tests that require a drop of saliva instead of a vial of blood will one day make a trip to a doctor or dentist much easier. But as scientists now construct the first of these saliva tests for early signs of cancer and other diseases, they continue to push the technological envelope in interesting ways.

Research team creates human ALS motor neurons

A team of researchers from the Harvard Stem Cell Institute (HSCI) and Columbia University, in a collaboration catalyzed by the Project A.L.S./Jenifer Estess Laboratory for Stem Cell Research, has demonstrated that pluripotent stem cells generated from a patient with ALS (amyotrophic lateral sclerosis) can be directed to differentiate into motor neurons - the very brain cells destroyed by ALS.

FDA clears test that determines what type of cancer cells are present in a malignant tumor

The U.S. Food and Drug Administration has cleared for marketing a test that can help health care professionals determine what type of cancer cells are present in a malignant tumor.

Stanford Medicine explores the complex world of clinical trials

Back just 100 years ago, the notion of testing treatments and drugs through randomized clinical trials was unheard of. Clinical trials began to proliferate only in 1800, placebos were first used in 1863 and randomization wasn't introduced until 1923.

Ultra-miniature bialy-shaped drug delivery particles

Ultra-miniature bialy-shaped particles - called nanobialys because they resemble tiny versions of the flat, onion-topped rolls popular in New York City - could soon be carrying medicinal compounds through patients' bloodstreams to tumors or atherosclerotic plaques.

Cranberry juice shows promise for urinary tract infections

For generations, people have consumed cranberry juice, convinced of its power to ward off urinary tract infections, though the exact mechanism of its action has not been well understood.

Stem cell chicken and egg debate moves to unlikely arena: the testes

Logic says it has to be the niche. As air and water preceded life, so the niche, that hospitable environment that shelters adult stem cells in many tissues and provides factors necessary to keep them young and vital, must have emerged before its stem cell dependents.

New super-resolution X-ray microscope

A novel super-resolution X-ray microscope developed by a team of researchers from the Paul Scherrer Institut (PSI) and EPFL in Switzerland combines the high penetration power of x-rays with high spatial resolution, making it possible for the first time to shed light on the detailed interior composition of semiconductor devices and cellular structures.

Proof-of-concept that purified muscle stem cells can be used in therapy

By injecting purified stem cells isolated from adult skeletal muscle, researchers have shown they can restore healthy muscle and improve muscle function in mice with a form of muscular dystrophy. Those muscle-building stem cells were derived from a larger pool of so-called satellite cells that normally associate with mature muscle fibers and play a role in muscle growth and repair.
