Understanding stroke: Symptoms and treatment

A stroke is a "brain attack" and occurs when blood supply to the brain is cut off. According to Kenneth A. Levin, M.D., Medical Director, The Valley Hospital Stroke Center, "Most strokes are caused by a blood clot that has built up on the wall of a brain artery or one that has traveled there from another part of the body (an embolic stroke or ischemic stroke).

Dutch scientists design self-destroying nanomotors to deliver and release drugs

Autonomous targeting and release of drugs at their site of action are desired features of nanomedical systems. Now, a team of Dutch scientists has designed a nanomotor that has these functions: An antitumor drug encapsulated in self-propelled, self-assembled stomatocytes is carried across the cellular membrane and released inside the cell upon a chemical redox signal that disassembles the vesicle membrane.

Philips sponsors research to help COPD patients breathe easier

Recently published advancements in pulmonary research suggest that the combination of non-invasive ventilation (NIV) and home oxygen therapy (HOT) can significantly prolong time to readmission or death for patients with chronic obstructive pulmonary disease (COPD) following a life-threatening respiratory event or exacerbation. The five-year, multi-center study resulted in prolonged median time to readmission or death by nearly three months, and improved patient health-related quality of life in the first six weeks.

Researchers discover new anti-thrombotic drug target for developing more protective blood thinners

Blood platelets shore up open wounds and help cuts heal, but they can also cause heart attacks and strokes when a congealed ball of platelets known as a thrombus breaks free from a site of injury and gets lodged in blood vessels that feed oxygen to the brain or heart.

Pulmonary thrombosis-on-a-chip enables unprecedented study of blood responses to organ-level injury

The average human pair of lungs is permeated by a network of about 164 feet of blood vessels (roughly the width of a football field), including microscopic blood capillaries, which facilitate the diffusion of oxygen into the bloodstream in exchange for carbon dioxide.
