Successful oral delivery of nanoparticle therapeutics
12/02/2013
Pop a pill or be poked by a needle? Being able to orally deliver microscopic particles - know as nanoparticles - loaded with medicine is a simple, convenient way to treat patients for various diseases, such as cancer or diabetes. But so far, nanoparticles can only be given via injection since they have trouble being readily absorbed by the intestine, which limits their usefulness.
Women who test negative for BRCA may not be at reduced risk of breast cancer
12/02/2013
Women who are members of families with BRCA2 mutations but who test negative for the family-specific BRCA2 mutations are still at greater risk for developing breast cancer compared with women in the general population, according to a study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
Mechanism discovered behind blood stem cells' longevity
12/02/2013
The blood stem cells that live in bone marrow are at the top of a complex family tree. Such stem cells split and divide down various pathways that ultimately produce red cells, white cells and platelets. These "daughter" cells must be produced at a rate of about one million per second to constantly replenish the body's blood supply.

Nausea is an unpleasant sensation of discomfort or unease in the stomach (queasy stomach), accompanied by an urge to vomit. Nausea often precedes vomiting.Nausea is not a disease in itself1, but rather a non-specific symptom, i.e.
New blood test 'can detect risk of infection in minutes'
12/01/2013
Scientists have created a device that is able to detect a person's risk of infection from a drop of blood within minutes, as opposed to current methods, which can take up to 2 hours. This is according to a study published in the journal Technology.

SignatureCLL have announced that the first laboratory test ever shown in a clinical trial to improve one year survival rates in cancer is now available to patients with chronic lymphocytic leukemia (also called CLL). The U.S.
New method found to increase survival in sepsis
11/30/2013
Sepsis, the body's response to severe infections, kills more people than breast cancer, prostate cancer and HIV/AIDS combined. On average, 30 percent of those diagnosed with sepsis die.A new study conducted by Jamey Marth, director of UC Santa Barbara's Center for Nanomedicine and professor of the Sanford-Burnham Medical Research Institute, reports a new method to increase survival in sepsis.
