Lead Exposure Plus High Blood Pressure May Impair Mental Ability
Exposure to lead in early childhood and adolescence may contribute to hypertension-related decline that can impair a person's cognitive abilities, according to a new study presented at the 2005 American Heart Association's High Blood Pressure Research meeting. Altered Sex Hormone Levels, Higher Body Temp Affects Sleep Quality In
In an examination of potential relationships between objective sleep measures, nocturnal sex hormone levels, and the nocturnal course of body temperature of older postmenopausal women, a new study finds that altered levels of both sex hormones and gonadotropins may contribute to sleep disturbance in older postmenopausal women and confirm the results of previous studies indicating that higher body temperature is associated with poorer sleep quality. Young Athletes' Post-concussion Migraine May Signal Greater Neurocogni
High school and college athletes with migraine headache characteristics after a concussion may have increased neurocognitive impairment, suggests a University of Pittsburgh Sports Medicine Concussion Program study published in the May issue of the Journal of Neurosurgery. The study results speak to the need for extreme caution in clinical evaluation and return-to-play decisions, say the authors. [Scary] Pregnant woman says 'maternal instinct' helped her kill attack
FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." Oncologists Show Focused Radiation Is Effective As Surgery Against Ner
Specifically aimed, "stereotactic"radiation may be as good as surgery -- and in some cases, even better -- in treating benign but potentially devastating brain tumors called nonacoustic schwannomas, according to a study by radiation oncologists. Futurists Foresee Rapid Growth In Global Travel

Gene Discovery Sheds Light On Brain's 'Wiring' Patterns
The complexity of the brain and, more specifically, how nerve cells form billions of contacts when there are fewer than 30,000 human genes is still a scientific mystery. A team headed by Drs. Robin Hiesinger and Hugo J. Bellen at Baylor College of Medicine in Houston have unraveled a piece of that puzzle by finding a gene that plays a key role in brain wiring. Far Flung Food: Europe's Distant Diets
Across the European Union, food is traveling more, and not always in ways that make sense. Consider the chocolate covered waffle: Last year, Britain both imported 14,000 tons, and exported 15,000 tons. And it is not just waffles that are traveling further, as Europeans are eating -- and importing -- more food from outside the EU than ever before. MyPyramid.gov
