Glia seem to play two opposing roles in protecting nerve cells from damage

A protein produced by the central nervous system's support cells seems to play two opposing roles in protecting nerve cells from damage, an animal study by Johns Hopkins researchers suggests: Decreasing its activity seems to trigger support cells to gear up their protective powers, but increasing its activity appears to be key to actually use those powers to defend cells from harm.

Secreted vesicles play role in spread of cancer

Cancer researchers have known for well over a century that different tumor types spread only to specific, preferred organs. But no one has been able to determine the mechanisms of organ specific metastasis, the so-called "soil and seed" theory of 1889. New details that could help shed light on this hypothesis have been provided by a team of researchers from Weill Cornell Medical College, Memorial Sloan-Kettering Cancer Center, and their collaborators, proposing a new mechanism controlling cancer metastasis that offers fresh diagnostic and treatment potential.

Pre-harvest vaccines for management of E. coli in Canadian beef receive favourable conclusion

Bioniche Life Sciences Inc., a research-based, technology-driven Canadian biopharmaceutical company, today announced that a Public Health Agency of Canada study assessing the effects of various interventions on the management of E. coli O157:H7 in Canadian beef came to a favourable conclusion with regard to pre-harvest vaccines such as the Company's Econiche cattle vaccine.

Mediterranean diet associated with mental and physical health

The study has been published in the 'European Journal of Clinical Nutrition.' For years the Mediterranean diet has been associated with a lesser chance of illness and increased well-being. A new study has now linked it to mental and physical health too.

Bioengineers develop first structure to grow small human blood vessels

Mice and monkeys don't develop diseases in the same way that humans do. Nevertheless, after medical researchers have studied human cells in a Petri dish, they have little choice but to move on to study mice and primates. University of Washington bioengineers have developed the first structure to grow small human blood vessels, creating a 3-D test bed that offers a better way to study disease, test drugs and perhaps someday grow human tissues for transplant.

Intensive glucose control associated with reduced risk of albuminuria

A review of data from seven clinical trials suggests that intensive glucose control is associated with reduced risk of microalbuminuria and macroalbuminuria (conditions characterized by excessive levels of protein in the urine usually resulting from damage to the filtering units of the kidneys), according to a report published in the May 28 issue of Archives of Internal Medicine, a JAMA Network publication.

New medicine can start and hasten healing of diabetic and other chronic sores

A unique new medicine that can start and hasten healing of diabetic and other chronic sores is being developed at Umeå University in Sweden. After several years of successful experimental research, it is now ready for clinical testing.

Researchers develop tentative model for diagnosis of colon cancer

Researchers from the Universidad Politécnica de Madrid's Facultad de Informática, the Universidad del País Vasco, the Gaiker Technology Centre (Biscay) and the Hospital de Cruces in Barakaldo, have developed a tentative model for the diagnosis of colon cancer based on a biomarker panel.

UC Davis mathematicians help biologists to understand platelet formation

UC Davis mathematicians have helped biologists figure out why platelets, the cells that form blood clots, are the size and shape that they are. Because platelets are important both for healing wounds and in strokes and other conditions, a better understanding of how they form and behave could have wide implications.

UCLA geneticists identify mutation responsible for IMAGe syndrome

UCLA geneticists have identified the mutation responsible for IMAGe syndrome, a rare disorder that stunts infants' growth. The twist? The mutation occurs on the same gene that causes Beckwith-Wiedemann syndrome, which makes cells grow too fast, leading to very large children.

ESRD patients with diabetes may benefit from Baxter’s low-glucose PD regimen

Baxter International Inc. today announced results from two large, international multicenter trials demonstrating that a low glucose peritoneal dialysis (PD) regimen favorably impacted metabolic measures important for end-stage renal disease (ESRD) patients with diabetes, including blood glucose (sugar) control and selected lipids.

City of Hope receives CIRM grant to develop T cell-based immunotherapy against glioma

City of Hope was granted a $5,217,004 early translational research award by the California Institute for Regenerative Medicine (CIRM) to support the development of a T cell-based immunotherapy that re-directs a patient's own immune response against glioma stem cells.

European CHMP issues positive opinion to Vertex's KALYDECO for treatment of CF

Vertex Pharmaceuticals Incorporated announced today that the European Committee for Medicinal Products for Human Use (CHMP) has issued a positive opinion by consensus recommending the approval of KALYDECO (ivacaftor) for people with cystic fibrosis (CF) ages 6 and older who have at least one copy of the G551D mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene.

MIT researchers engineer new jet-injection system

MIT researchers have engineered a device that delivers a tiny, high-pressure jet of medicine through the skin without the use of a hypodermic needle. The device can be programmed to deliver a range of doses to various depths - an improvement over similar jet-injection systems that are now commercially available.
