Enhanced Degradation of Rhodamine B by Metallic Organic Frameworks Based on NH-MIL-125(Ti) under Visible Light.

Samples of the bimetallic-based NH-MIL-125(Ti) at a ratio of M/Ti is 0.15 (M: Ni, Co and Fe) were first synthesized using the solvothermal method. Their fundamental properties were analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectra, scanning electron microscopy (SEM), N adsorption-desorption measurements, and UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS).

Primary drug-resistant tuberculosis in Hanoi, Viet Nam: present status and risk factors.

Introduction: Resistance of Mycobacterium tuberculosis (MTB) to anti-tuberculosis (TB) drugs presents a serious challenge to TB control worldwide. We investigated the status of drug resistance, including multidrug-resistant (MDR) TB, and possible risk factors among newly diagnosed TB patients in Hanoi, the capital of Viet Nam.

Methods: Clinical and epidemiological information was collected from 506 newly diagnosed patients with sputum smear- and culture-positive TB, and 489 (96.
