* Baby teeth are a potential source of progeny cells. In a study published in the Proceedings of the National Academy of Sciences and summarized in a BMJ just discovereds brief, researchers found that the dental soft mass of front incisor teeth contains robust stalk cells. The researchers were able to isolate the main stock cells from the baby teeth of children seven to eight years of age. According to the stranges brief, stem cells from tooth soft part could be an uncontroversial alternative to embryonic descendant cells.

* What's in the bottle? When it get tos to echinacea, it's anyone's gues According to a inquiry published in Archives of Internal Medicine, thin-layer chromatography revealed no measurable traces of the herb in six of 59 echinacea add tos sold in retail stores in the Denver area. Researchers leadershiped tests on single-herb echinacea preparations in tablet, liquid, and other forms. Of 21 preparations that were labeled "standardized," barely nine met the quality standard described forward the label. Overall, the researchers base that the quality standard of the production was as described on the label in 31 (52 percent) of 59 echinacea supplements

* Men with a particularly fervid sense of taste may be at increased risk for obesity, cancer, and other health point in disputes according to findings presented at a meeting of the American Association for the Advancement of Science. As reported in Science, single in kind study found that men 65 years and older with a greater sensitivity to bitter tastes, similar as those found in vegetable adjusts were more likely to make known colorectal polyps; these men ate fewer vegetables and were likely to be overweight (both risk factors for colon cancer). Another subject of attention found that men, particularly "supertasters," who had a history of ear infections were more likely to be overweight because of damage to a manhood that controls taste and fat sensation. The findings reveal that taste perception may influence diet enough to affect a person's health.

* Will it be a boy? Will it be a girl? Watch in what way much the pregnant woman is eating! A inquiry published in BMJ shows that pregnant women who are carrying male childs have a 10 percent higher bottom intake than those who are carrying girls. In an analysis of data from an international prospective investigation researchers assessed the dietary intake of 244 U women during their other trimester. Women carrying boys, rather than girls, had higher intakes of protein (8 percent) carbohydrates (92 percent) lipids of animal origin (109 percent) and lipids of vegetable origin (149 percent) The researchers speculated that the strenuously anabolic testosterone secreted by the fetal testicles could be responsible for the higher might intake of women carrying boys

* Bigger portions, bigger kids? A investigation published in the American Journal of Clinical Nutrition proposes that children eat more when they are serv large portions of cheer At two series of lunches, researchers serv 30 preschool-aged children an age-appropriate portion of an admission or a portion that was twice as large. Each series consisted of individual meal a week for four weeks; the series were divided on a two-week period of self-serv portions. When the children were serv the large admittance they took bigger bites and ate more, equal though most of them appeared unaware that the portion size had changed. However, when they were allowed to assist themselves, they ate 25 percent les of the [i]entremet[/i] than when they were serv the large portion size.
