Circulating miR-122-5p as a potential novel biomarker for diagnosis of acute myocardial infarction.

Background: MicroRNAs (miRNAs) play key roles in cardiac development, and the expression of miRNAs is altered in the diseased heart. The aim of this study was to explore the value of circulating microRNA-122-5p (miR-122-5p) as a potential biomarker for acute myocardial infarction (AMI).

Methods: Plasma samples from 50 patients with AMI and 39 healthy adults (non-AMI controls) were collected.

Synthesis of Tat tagged and folate modified N-succinyl-chitosan self-assembly nanoparticles as a novel gene vector.

The purpose of this research was to prepare a novel type of Tat tagged and folate modified N-succinyl-chitosan (Tat-Suc-FA) self-assembly nanoparticles, to provide a new vector for tumor gene therapy. In this study, Tat-Suc-FA polymers was synthesized and characterized using (1)H NMR and FT-IR. The copolymer had a mean diameter of 65 ± 22.

[A new spectral method for the determination of cationic surfactant based on the resonance scattering effect of AgI2- association particles].

In pH 3.5 NaAc-HCl medium, there is a maximum resonance scattering (RS) peak at 360 nm and a synchronous scattering peak at 470 nm for the association particle system of (CTMAB-AgI2)n in white color, with a diameter of 700 nm. The CTMAB concentration cCTMAB in the range of 2.
