Can food urges be irresistible?

body has a physiological predisposition to balance its energy needs with its desire for food. The hormones and brain communicate to determine when an individual is full, with the brain issuing the signal that says "Stop eating" with the help of information it receives from hormones. But prolonged food shortages, chronic stress, prenatal nutrition, early exercise patterns and other factors can affect how the brain orchestrates this balance. In places where food is scarce, the brain may encourage higher consumption, especially of high fat and sugary foods, even when the food supply becomes more abundant. That's an adaptive response that helps the body weather periods of food shortages

brain may also respond to stress in the same way, encouraging the intake of high fat and sugary foods - comfort foods - that can result in obesity that is nearly impossible to reverse.

葡萄汁能防心脏病

法国科学家发现，葡萄汁有助于防止心脏病，效果可媲美葡萄酒。

　　法国路易巴斯德大学研究员早前就葡萄汁对心脏的影响进行研究后公布，葡萄汁与葡萄酒一样可以防止心脏病。

　　这是因为同样从葡萄提炼出来的葡萄酒与葡萄汁，都含有丰富的多元酚类（Polyphenols）这种强效的抗氧化剂，能帮助身体对抗心血管疾病。

　　另外，葡萄汁内的多元酚类也可令内皮细胞制造一氧化氮，保持血压及血流健康，有助对抗心脏病。

心脏干细胞治疗

研究出这种治疗的以色列喜瑞达公司(TheraVitae)说,大部分患者都是严重心脏病,而且在其他疗法失败后,来接受干细胞治疗的。
在治疗开始时，先从病人体内抽取三分之一升血液，送到以色列的喜瑞达实验室，取出血液里的干细胞加以复制。

　　这些干细胞然后空运回曼谷，直接植入病人的心脏，希望能强化病人衰弱的心脏。

1 Dose Of New Drug Cures Malaria

Hopkins University researchers have cured infected mice with single shots of a new series of potent, long lasting synthetic drugs modeled on an ancient Chinese herbal folk remedy.

These peroxide compounds, containing a crucial oxygen-oxygen unit

The oxygen-oxygen unit in the peroxides causes malaria parasites essentially to self-destruct. The parasites digest hemoglobin, the oxygen-carrying pigment of red blood cells, and, in the process, release a substance called heme, a deep-red iron-containing blood pigment. When the heme encounters peroxides, a powerful chemical reaction occurs, releasing carbon-free radicals and oxidizing agents that eventually kill the parasites.

Palm oil killing rainforest

Palm-oil consumption has more than doubled to more than 30 million tonnes each year in the past decade. But the environmentally conscious people around the globe who have driven the demand 'haven't realized that they're destroying Indonesia's nature in the process,' said

女性患肺癌风险比男性高

相同年龄层、拥有等长抽烟史和等量烟瘾的男女相较，女性罹患肺癌的风险仍高出男性很多

因抽烟得肺癌而丧命的美国妇女，在过去近70年来不断增加。据估计，从60年代至今，美国男性患肺癌的人数约已减半，而同一时期妇女患肺癌者只减少四分之一。

human Rh proteins

Thousands of people with liver and kidney disease die every year from too much ammonia in their blood.......
a possible solution....
By targeting human Rh proteins, new treatments will help people with damaged livers and kidneys remove toxic ammonia from their bloodstream.
For people with kidney and liver damage, the need to remove naturally occurring ammonia from the bloodstream is critical. Brain cells are particularly susceptible to ammonia, and at low levels, ammonia toxicity can cause mild to severe confusion, drowsiness, or tremors. At high levels, ammonia toxicity leads to coma and eventually death. Rh blood proteins are most commonly recognized as being used to help define blood type. For instance, people who are type A, B, AB, or O positive have Rh blood proteins on the surface of their red blood cells. People who are type A, B, AB, or O negative do not have Rh proteins on the surface of their red blood cells.
