Relationship between plasma levels of 25-hydroxyvitamin D and arterial stiffness in elderly Chinese with non-dipper hypertension: An observational study.

Elderly individuals with non-dipper hypertension are at high risk of cardiovascular disease because of increased stiffness of peripheral arteries. Since, vitamin D deficiency is prevalent in elderly Chinese. We examined whether reduced plasma levels of 25-hydroxyvitamin D [25(OH)D] may help promote this stiffness.

One-pot hydrothermal synthesis of uniform β-MnO2 nanorods for nitrite sensing.

A simple hydrothermal method was developed for the synthesis of uniform single-crystal β-MnO(2) nanorods only using potassium permanganate and sodium nitrite in acidic solution, without any seed or template. The as-prepared β-MnO(2) nanorods have the average diameter of 300±20 nm and a length up to 1.2±0.

Spermine-graft-dextran non-covalent copolymer as coating material in separation of basic proteins and neurotransmitters by capillary electrophoresis.

Spermine-graft-dextran (Spe-g-Dex) copolymer was synthesized and used as a non-covalent coating for the separation of proteins and neurotransmitters by capillary electrophoresis. The coating was obtained via flushing the capillary with 1.0% Spe-g-Dex copolymer solution for 2min.
