‘Brain freeze’ provides clue to migraine cause and therapy

According to latest reports by researchers the headache that is caused by eating something cold like an ice cream, may be caused by a sudden change in brain blood flow. The U.S. team of researchers add that this study may show targets to treat other, more troubling forms of headache such as migraine.

Nanoscale films promote bone growth

Every year, more than a million Americans receive an artificial hip or knee prosthesis. Such implants are designed to last many years, but in about 17 percent of patients who receive a total joint replacement, the implant eventually loosens and has to be replaced early, which can cause dangerous complications for elderly patients.

CPMC surgeons successfully reattach forehead and scalp of a 22-year-old Stockton woman

Surgeons at the renowned Buncke Clinic at California Pacific Medical Center, part of the Sutter Health network, have successfully reattached the forehead and scalp of a 22-year-old Stockton woman whose hair was caught in machinery at her workplace. This type of surgery is extremely rare, and has been successfully performed only a handful of times world-wide.

Researchers discover new stem cell in the adult brain

Researchers at Lund University in Sweden have discovered a new stem cell in the adult brain. These cells can proliferate and form several different cell types -- most importantly, they can form new brain cells. Scientists hope to take advantage of the finding to develop methods to heal and repair disease and injury in the brain.

Testosterone may help heart failure patients: Study

The researchers used testosterone patches and injections that improved the breathing and exercise abilities of people with heart failure, a chronic inability of the heart to pump enough blood to the rest of the body. Although most of the study participants were men, the researchers said the results would likely apply to women as well, through much smaller doses of testosterone.

Engineered particles tied to penetratin discover, deliver ligands for mitochondria, ribosomes

Scientists who developed a technology for identifying and targeting unique protein receptor ZIP Codes on the cellular surface have found a way to penetrate the outer membrane and deliver engineered particles - called iPhage - to organelles inside the cell.

Tumor microenvironment contributes critically to drug response

It should be possible to significantly improve the response of common cancers to existing "classical" chemotherapy drugs, say scientists at Cold Spring Harbor Laboratory (CSHL), by introducing agents that alter the interaction of cancer cells with their immediate surroundings, called the tumor microenvironment.

Study: Kidney cancer growth depends on autophagy

New research at the University of Cincinnati (UC) suggests that kidney cancer growth depends on autophagy, a complex process that can provide cells with nutrients from intracellular sources. Researchers say in certain circumstances autophagy can protect tumor cells from chemotherapy, allowing them to survive for long periods of time in a hidden, dormant, metastatic state.
