[Study of nondestructive and fast identification of fabric fibers using near infrared spectroscopy].

A fast and nondestructive identification method to distinguish different types of fabric fibers is proposed in the present paper. A total of 214 fabric fiber samples, including wool, cashmere, terylene, polyamide, polyurethane, silk, flax, linen, cotton, viscose, cotton-flax blending, terylene-cotton blending, and wool-cashmere blending, were collected from Beijing Textile Fibre Inspection Institute. They contain yarns, raw wool or cashmere, and various fabric straps with different colors and different braid patterns.

Efficacy and safety of escitalopram versus citalopram in major depressive disorder: a 6-week, multicenter, randomized, double-blind, flexible-dose study.

Rationale: S-citalopram (escitalopram) is the very active moiety of citalopram. It has been shown in many studies to be an effective and safe antidepressant for treating major depressive disorder (MDD).

Objective: The aim of our study was to compare the efficacy and safety of escitalopram vs citalopram in Chinese MDD patients.

[Detection of streptomycin resistance in Mycobacterium tuberculosis clinical isolates by denaturing high-performance liquid chromatography and DNA sequencing].

Objective: To determine the rpsL and rrs gene mutation in Mycobacterium tuberculosis (M. tuberculosis) and compare the consistency between the results of denaturing high-performance liquid chromatography (DHPLC) and those of DNA sequencing.

Methods: The values of streptomycin minimum inhibitory concentration (MIC) against 215 M.
