in this work, sol-gel processing was used to synthesize the fluorohydroxyapatite (nano-fha, ca10(po4)6(oh)2−xfx) nanopowders. the advantages of the sol-gel method over other methods are precise control of composition, low processing temperature, and better homogeneity. calcium nitrate tetrahydrate, phosphorous pentoxide and tetrabuthylammonium fluoride were used, respectively, as p, ca, and f p...
A nontoxic, simple, inexpensive, and reproducible strategy, which meets the standard of green chemistry, is introduced for the synthesis of copper nanocrystals (Cu NCs) with olive oil as both reducing agent and capping agent. By changing the reaction parameters, the shape, size and surface structure of the Cu NCs can be well controlled. The obtained Cu nanocubes show excellent catalytic propert...
Lipopolysaccharide (LPS) (a.k.a., endotoxin) is an essential component of the outer leaflet of the outer membrane of gram-negative bacteria and is a potent activator of the innate immune system of animals. Lipid A, the glycolipid core of LPS, is the agent responsible for disease and death from gram-negative sepsis, an important cause of human mortality and morbidity. Although it is generally ac...
Bile acid binding capacity has been related to the cholesterol-lowering potential of foods and food fractions. Lowered recirculation of bile acids results in utilization of cholesterol to synthesize bile acid and reduced fat absorption. Secondary bile acids have been associated with increased risk of cancer. Bile acid binding potential has been related to lowering the risk of heart disease and ...
