"Welcome to the Ark" is a wonderful read. Though a bit fantastic.
Our English teacher gave us some articles to puruse. Several I found interesting. Posted below.
Chemo Has Long-term Impact on Brain Function(Washington, Reuters Health, 10/5/06)
Daniel Silverman of UCLA, Los Angeles, and team, studied 21 women whose breast tumors had been surgically removed. Sixteen had received chemotherapy and five had not. When the investigators compared positron emission tomography (PET) scans of the brains of these women with those of 13 others who had not had breast cancer, the scientists found that subjects who had undergone chemotherapy five to 10 years earlier had lower metabolism in key areas of their brains. These findings indicate that chemotherapy may produce long-term changes in brain metabolism that cause the cognitive dysfunction and confusion, dubbed hemo brain,?which patients often experience after undergoing treatment.

Red wines slows alzheimer's-like disease in mice
Giving mice with Alzheimer-like disease the equivalent of a couple of glasses of red wine daily slows memory loss and brain cell death, a new study shows.
The researchers calibrated the animals?wine intake to match the US Department of Agriculture definition of moderate wine consumption, a single 5-ounce glass daily for women and two glasses for men. oderate consumption is the key factor,?Dr. Giulio Maria Pasinetti of the Mount Sinai School of Medicine in New York City said.
On a random basis, Pasinetti and his team gave mice cabernet sauvignon or ethanol -- the type of alcohol found in alcoholic beverages -- in their drinking water for seven months. Another group of mice drank plain water. All of the animals had a genetic defect that caused them to develop amyloid plaques in their brains, the type of damage that occurs in humans with Alzheimer disease.
The researchers then tested the animals?memory by putting them through a series of maze tests, after the animals had been alcohol-free for three days. The wine-drinking mice learned how to escape from the maze significantly faster than those drinking alcohol-spiked water or water only.
Based on the findings, and given that moderate wine consumption may protect the heart, Pasinetti said, older people in good health who don have the metabolic syndrome, high blood pressure, liver problems, issues with alcohol dependence or other reasons to avoid alcohol can choose to drink red wine moderately as part of a healthy lifestyle.
Drinking wine, he noted, is good lifestyle factor that everybody appears to like.?BR>

Eating Vegetables May Help Slow Memory Loss in Elderly
By Rose Hoban Chapel Hill, NC30 October 2006
New research from the Rush University Medical Center in Chicago indicates your mother was right: eating vegetables is good for you. Epidemiologist Martha Clare Morris found that eating vegetables every day seems to slow mental decline and the development of Alzheimer's disease in old age.
Morris has been looking at the eating habits of thousands of elderly Chicago residents for more than a decade. "Every 3 years we go into their homes and ask them all sorts of questions about their health and lifestyle," she explains. "But also, we administer tests that measure their thinking ability. So that we can look at changes in their thinking ability over time."
Morris had people record the kinds of fruits and vegetables they ate and how often. She found that people who ate more servings of vegetables per day had memories that deteriorated more slowly than those who didn't eat vegetables. "People who consumed two to three vegetable servings per day had a 40 percent reduction in the rate of their decline in their thinking ability, compared to people who consumed around one or no servings of vegetables a day." Eating fruits didn't do as much to preserve thinking ability as eating vegetables.
Morris found that some kinds of vegetables are better than others at preventing memory loss. She asked study participants about green leafy vegetables, yellow vegetables, cruciferous vegetables like broccoli and legumes, or beans. "The more green leafy vegetables they consumed, the slower their rate of decline in thinking ability," she reports. "We also found evidence of association with the other types of vegetables, except for legumes. But the relation was not as strong as for green leafy
vegetables." Morris believes the benefit was derived from those vegetables with especially high levels of vitamin E.
