Researchers caution against linking strep, neuropsychiatric disorders
...oo vague. For instance, one PANDAS hallmark is the abrupt onset of symptoms but oftentimes once parents learn more about tics, they realize that their children have had them for quite awhile. The researchers say that while strep has been linked to other disorders such as rheumatic fever and Sydenham's chor...Alternative states in the ocean
...asionally, however, such variation can be severely abrupt and lead to formation of alternative and potentially persistent states. In the July issue of Ecology Letters, Paine and Trimble describe a dramatic assemblage shift on a rocky intertidal shore in Washington State (USA).

...entists studied the phenomenon of cataplexy -- the abrupt loss of muscle tone while maintaining a state of complete wakefulness. The majority of narcoleptics suffer from this malady, in which a strong emotion, even a funny joke, can cause them to drop into a state of paralyzed awareness ranging from a few s...Floods, bugs and Hollywood disasters

...ation is that the 17-OHP increase in PCOS reflects abrupt (in comparison to normal) rhLH-induced resumption of early steroidogenic steps after temporary removal of physiological LH stimulation. The findings revealed that leuteinizing hormone dose-ovarian steroid responses were not observed in normal women. ...Researchers identify gene for a primary form of sudden infant death sydrome (SIDS)
...infants with SIDDT died before 12 months of age of abrupt cardiac and respiratory arrest. While many of these infants underwent testing at major medical centers, no abnormalities were found. Males with SIDDT may also have underdeveloped testes.

...t in the deep Earth, and was thought to undergo an abrupt transformation from low to high density forms. This study shows a more complex slow transformation -- a significant finding with general implications for glass chemistry. The work, which will be featured an upcoming issue of Physical Review Letters, ......uthors observed a pronounced pause, followed by an abrupt increase in polymerization rate. Since the length of the pause showed only a weak dependence on the concentration of monomers, Weissman and colleagues explain, this finding could not be explained by a simple model of nucleation polymerization, in whi...
