New study reveals an unexpected survival mechanism of a subset of cancer cells

Embedded at the ends of chromosomes are structures called telomeres, which in normal cells become shorter as cells divide. Progressive shortening triggers cell proliferation arrest or death. Cancer cells adopt different strategies to overcome this control mechanism that keeps track of the number of times that a cell has divided. One of these strategies is the alternative lengthening of telomeres […]

Take steps to prevent a stroke

(HealthDay)—Strokes are common but not inevitable. There are ways you can reduce your risk, starting with your blood pressure. Stroke is the fifth leading cause of death in the United States and the leading cause of permanent disability, said Dr. Gary Bernardini, neurology chair at New York-Presbyterian Hospital Queens. Most strokes occur when blood flow to the brain gets cut […]

A new clue in the mystery of ALS, frontotemporal dementia

A special focus on rogue proteins may hold future promise in stopping the progression of nerve cell destruction in people who have amyotrophic lateral sclerosis (ALS) or frontotemporal dementia. ALS, a rare but devastating disorder that’s also known as Lou Gehrig’s disease, attacks the body’s nerve cells, resulting in progressive muscle weakness as the neurons degenerate over time. There is […]

Shining light on rare nerve tumors illuminates a fresh path for fighting cancer

When a protein named “Merlin” fails to do its job, people can develop slow-growing, life-disrupting auditory nerve tumors that can disrupt their hearing and balance. This rare condition is called neurofibromatosis 2 (NF2). Now scientists at Cincinnati Children’s have discovered much more about how Merlin does its job—by working behind the scenes through a network of more than 50 other […]

Scientists restore some functions in a pig’s brain hours after death

Circulation and cellular activity were restored in a pig’s brain four hours after its death, a finding that challenges long-held assumptions about the timing and irreversible nature of the cessation of some brain functions after death, Yale scientists report April 18 in the journal Nature. The brain of a postmortem pig obtained from a meatpacking plant was isolated and circulated […]
