According to the information supplied by resveratrol manufacturer, the highest content of resveratrol is Aster plants in Japan, followed by grape skins. Red wine, pure grape juice, peanuts, cranberries, blueberries, bilberries and some the pine also contain resveratrol, the concentration is slightly lower than the first two things.
Grapes and other plants manufacturing resveratrol is for fighting fungal infections, injury, stress; is part of their natural resist system. The amount of resveratrol in red wine is different from geographical production areas, cultivation conditions, fungal infections, as well as red wine and grape skins mixed time. The content of resveratrol in red wine is from less than 1 mg per liter to more than 20 milligrams per liter.
Red wine contains strong and effective polyphenol antioxidants: resveratrol, anthocyanins (the pigmented substances in grape skin), proanthocyanidins (common in grape seed), catechol and quercitrin. Use mice as experimental research show that resveratrol in the prevention of prostate cancer, colon cancer, and thymic carcinoma. Resveratrol showed multiple stages in the development of cancer, including tumor initiation, tumor induction period, the period of tumor development and metastatic the antagonism can play. Allegedly a week often drink three glasses of red wine and even more among the 3% of colon polyps or colon cancer, while drinking more than 3 cups white wine (white wine grape skin fermentation time is shorter, containing resveratrol week the amount of alcohol is less), the ratio is 9%. Compared the results of no drinking and the results of people drinking white wine is similar.
Resveratrol as pharmaceutical raw materials also can be called red wine or pure grape juice, the suffering Alzheimer's mouse experiments showed that they can protect the brain and cognitive function, and alcohol (equivalent to the percentage of ethanol in wine) or water without protection function. Red wine in the protective effects of alcohol on the brain and cognitive function has no effect. One of the mechanism of Alzheimer is ²-amyloid produce excessive, and subsequently cause brain damage. Resveratrol motivated a sirtuin protein, people found sirtuin protein can protect neurons against beta-amyloid - induced free radical damage of DNA. Resveratrol promote dangerous beta-amyloid diminishes. It is thus assume that resveratrol may prevent age-related neurodegenerative diseases, such as Alzheimer's disease.
Compared with nondrinkers aging population older persons of Chinese nationality, little product or moderate alcohol consumption make the risk of suffering from Alzheimer's disease lower 37%, and vascular dementia is as low as 69%. In contrast, excessive alcohol consumption will be increased the risk of dementia. Slightly moderate alcohol consumption may significantly reduce the risk of dementia. Compared with people who never drink beer and slightly moderate drinking beer, the risk of dementia may be significantly higher. In a study from France, the daily consumption of 3-4 glasses of wine, the risk of suffering from Alzheimer's disease fell by 75%, and drink less than one glass of wine a day is reduced by 45%.
Sirtuin protein manage gene silencing, DNA repair, mitochondrial function, control of cell aging and arrange for their deaths. 95% of our cellular energy from mitochondrial manufactured end product of adenosine triphosphate (ATP), ATP is the energy chemical repository. The number of mice treated with resveratrol increases, the mitochondrial energy produced increases, oxygen capacity increases.

The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
