Mice with a migraine show signs of brain damage

...xygen. The problem begins as the brain tries to recover from CSD, which throws the proportion of crucial ions like potassium and sodium out of balance, taking away the brain’s ability to function efficiently. This change in the proportion of chemicals gradually sweeps across the brain like a slowly spread...

Amphibians in losing race with environmental change

...ion may, in time, allow amphibians to react to and recover from the new environmental insults, Blaustein said, if they don't go extinct first. But evolution is an erratic, often slow and imperfect system, and the complexities of amphibian life cycles makes them more immediately vulnerable than many other ...

...vibration) of tissue, as well as how the voice can recover from physical stress (5aSC12). DETECTING BREAST LESIONS WITH VIBRO-ACOUSTOGRAPHY Vibro-acoustography (VA) is a non-invasive imaging technique using ultrasound to search for lesions in breast tissue. Generally the rival approaches to breast i...

Proteasome activator enhances survival of Huntington's disease neuronal model cells

...sion of proteasome activator PA28 can specifically recover proteasome function and improve cell viability in both HD model and patient cells. These remarkable results demonstrate for the first time that it is possible to intervene therapeutically in the proteolytic pathways and organelles that participat...

Row over study puts Korea's scientific community under scrutiny again

Cold sore virus might play role in Alzheimer's disease

...le with the ApoE-4 gene, brain cells don't seem to recover as well from injury, and the cells don't form new connections as well as cells equipped with either ApoE-2 or ApoE-3. Other scientists have shown that the gene plays a role in clearing toxic amyloid beta from the brain. "Just how ApoE-4 makes peop...

Saving endangered whales at no cost

...s, the North Atlantic right whale has been slow to recover from past exploitation, and extinction remains a threat. The whale is virtually extinct in Europe, but a small population of about 350 individuals remains on the east coast of North America. A leading threat to the species is lethal entanglement by f...

Long-lived deep-sea fishes imperiled by technology, overfishing

...atened by over-fishing and the species' ability to recover is constrained by the fishes' long lifespans and low reproductive success, a panel of experts said today at the annual meeting of the American Association of the Advancement of Science. Some of the fish species living at depths greater than 500 mete...

Seals protect brain, conserve oxygen by turning off shivering response on icy dives

...hat they use nearly all their oxygen, but they can recover with these special adaptations. Humans cannot tolerate oxygen levels nearly so low as a seal can. "Somehow they tolerate hypoxia better, we don't know why," Folkow said. The study of how seals handle this lack of oxygen may someday give us knowled...

Brains can recover from alcoholic damage but patients should stop drinking as soon as possible

...wth. Our findings show the ways that the brain can recover from the toxic insults of chronic alcoholism and substantiate the early measurable benefits of therapeutic sobriety. However, they also suggest that prolonged dependence on alcohol may limit rapid recovery from white matter brain injury. "Modern n...
