UC Irvine study: Small amount of brain bleeding is common among older individuals

Neurologist Dr. Mark Fisher and neuropathologist Dr. Ronald Kim found that cerebral microbleeds are highly prevalent in the aging brain - and not primarily products of stroke-related injury, hypertension or neurodegenerative diseases such as Alzheimer's, as had been thought.

Scientists develop nanobioconjugate drug to target brain tumor

Nine years ago, scientists at Cedars-Sinai's Maxine Dunitz Neurosurgical Institute detected a subtle shift occurring in the molecular makeup of the most aggressive type of brain tumors, glioblastoma multiforme. With further study, they found that a specific protein called laminin-411 plays a major role in a tumor's ability to build new blood vessels to support its growth and spread. But technology did not exist then to block this protein.

Research reveals EBV virus infected cell manipulates cancer-producing cells

A new discovery by UNC scientists describes how cells infected by the Epstein-Barr virus (EBV) produce small vesicles or sacs called exosomes, changing their cellular "cargo" of proteins and RNA. This altered exosome enters cells and can change the growth of recipient cells from benign to cancer-producing.

Resveratrol in grapes may help fight severe malaria: Study

A compound found in the skin of grapes and used to make red wine may help fight severe malaria, raising hopes of finding a new adjunctive therapy against an illness that kills an estimated 1 million people a year, according to a study presented today at The American Society of Tropical Medicine and Hygiene 59th Annual Meeting.

Novel serum test may help diagnose early pregnancy location and outcome

Researchers may have identified a promising novel diagnostic biomarker for ectopic pregnancy, according to a study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). In the western world, deaths from ectopic pregnancy are not common but in the developing world one in ten women who are admitted with an ectopic pregnancy die.

LVI in breast tissue predicts recurrence of breast cancer in regional lymph nodes

Breast cancer, one of the most prevalent cancers in women, afflicts an additional 200,000 women each year and causes about 40,000 deaths annually. The disease often extends to neighboring lymph nodes, in part, through lymphovascular invasion (LVI)-a process in which cancer cells invade blood vessels or the lymphatic system-and can often translate into a poor prognosis for patients.

Drinking beet juice increases blood flow to the brain

Researchers for the first time have shown that drinking beet juice can increase blood flow to the brain in older adults - a finding that could hold great potential for combating the progression of dementia.

New laboratory-engineered livers could provide solution to donor shortage

Researchers at the Institute for Regenerative Medicine at Wake Forest University Baptist Medical Center have reached an early, but important, milestone in the quest to grow replacement livers in the lab. They are the first to use human liver cells to successfully engineer miniature livers that function - at least in a laboratory setting like human livers. The next step is to see if the livers will continue to function after transplantation in an animal model.
