TL;DR: An electrochemically functional nanocomposite through the adsorption of methylene blue onto the multi-walled nanotubes (MB-MWNTs) was prepared, and a sensitive voltammetric sensor was fabricated as mentioned in this paper.
Abstract: An electrochemically functional nanocomposite through the adsorption of methylene blue onto the multi-walled nanotubes (MB-MWNTs) was prepared, and a sensitive voltammetric sensor was fabricated. The modified electrode showed excellent electrocatalytic activity toward dopamine (DA) and uric acid (UA) in 0.1 M phosphate solution medium (pH 3.0). Compared to the bare electrode, the MB-MWNTs film-modified electrode not only remarkably enhanced the anodic peak currents of DA and UA, i.e., shifted the anodic peak potential of DA negatively, but also avoided the overlapping of the anodic peaks of DA and UA. The interference of ascorbic acid (AA) was eliminated. Under the optimized conditions, the peak separation between AA and DA and between DA and UA was 219 and 174 mV, respectively. In the presence of 1.0 mM AA and 10.0 μM UA, the anodic peak current was linear to the concentration of DA in the range of 0.4–10.0 μM with a detection limit of 0.2 μM DA. The anodic peak current of UA was linear to the concentration in the range of 2.0–20.0 and 20.0–200.0 μM with a lowest detection limit of 1.0 μM in the presence of 1.0 mM AA and 1.0 μM DA.

TL;DR: It was concluded that SE possessed the same cholesterol-lowering activity as β-sitosterol and the underlying mechanisms were mediated by increasing sterol excretion and decreasing cholesterol absorption and synthesis.
Abstract: The present study examined the cholesterol-lowering activity of sterol extract (SE) derived from alga Schizochytrium sp. and its interaction with gene expression of transporters, receptors, and enzymes involved in cholesterol absorption and metabolism. GC-MS analyses found that SE was a mixture of various sterols including lathosterol, ergosterol, stigmasterol, 24-ethylcholesta-5,7,22-trienol, stigmasta-7,24(24(1))-dien-3β-ol, and cholesterol. Results showed that SE at doses of 0.06 and 0.30 g/kg diet were able to decrease plasma cholesterol concentration by 19.5 and 34%, respectively, compared with the control, in hamsters maintained on a 0.1% high-cholesterol diet. SE at a dose of 0.30 g/kg diet was as effective as β-sitosterol in reducing plasma total cholesterol (TC). SE-induced reduction in plasma TC was accompanied by down-regulation of intestinal acyl-CoA:cholesterol acyltransferase 2 (ACAT2) and hepatic 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase and up-regulation of hepatic low-density lipoprotein (LDL) receptor. Addition of SE to the diet increased the excretion of total fecal sterols. It was concluded that SE possessed the same cholesterol-lowering activity as β-sitosterol and the underlying mechanisms were mediated by increasing sterol excretion and decreasing cholesterol absorption and synthesis.

TL;DR: A novel and convenient palladium-catalyzed direct oxidative amidation of quinoxalin-2(1H)-ones with acetonitrile was developed and provided a practical approach to various 3-acetamino quinxalin-1H-ones from the readily available starting material acetonijile.
Abstract: A novel and convenient palladium-catalyzed direct oxidative amidation of quinoxalin-2(1H)-ones with acetonitrile was developed to synthesize 3-amidated quinoxalin-2(1H)-ones. A series of 3-acetamino quinoxalin-2(1H)-one derivatives were constructed with good to excellent yields. This methodology provided a practical approach to various 3-acetamino quinoxalin-2(1H)-ones from the readily available starting material acetonitrile.
