This phenomenon is known as gravity. More massive objects have a stronger pull than less massive objects. This is why you weigh more on larger, more massive planets like Jupiter and less on smaller, less massive planets like Mars. The mass of an object depends not only on its size, but also its composition.
Nifedipine is approved to control high blood pressure and angina (chest pain). Classified as a calcium-channel blocker, nifedipine blocks the passage of calcium into cardiac and smooth muscle, like those of the uterus. And calcium is needed for the uterus to contract. Nifedipine is one of the most widely used and studied medications among the calcium-channel blockers to suppress preterm contractions. But the use of tocolytics is controversial. In 80 percent of women with suspected preterm labor, early delivery will not occur.
Like the other B complex vitamins, niacin is important in energy production. Two unique forms of vitamin B3 (called nicotinamide adenine dinucleotide, or NAD, and nicotinamide adenine dinucleotide phosphate, or NADP) are essential for conversion of dietary proteins, fats, and carbohydrates into usable energy.ix of these contain 50% or more of the DRI recommendation for the nutrient. The good sources of niacin come from many different food groups. We see legumes (particularly peanuts and green peas) represented. A number of vegetables, particularly root vegetables and leafy greens, also show up as good niacin sources.
