SARS: pharmacotherapy [PDF]

open access: yesRespirology, 2003
The pharmacotherapy for severe acute respiratory syndrome (SARS) is controversial and largely anecdotal. Most patients with suspected SARS should initially be treated with potent antibiotics before proceeding to ‘anti‐SARS’ therapy. There is a spectrum of severity and rate of progression in SARS, and the stages of viral replication, inflammatory ...

Monitoring the built-up environment of Shanghai on the street-block level using SAR and volunteered geographic information

open access: yesInternational Journal of Digital Earth, 2017
In this geo-statistical analysis of change detection, we illustrate the evolution of the built-up environment in Shanghai at the street-block level. Based on two TerraSAR-X image stacks with 36 and 15 images, covering the city centre of Shanghai for the ...

Synthesis of Novel Triazinoindole-Based Thiourea Hybrid: A Study on α-Glucosidase Inhibitors and Their Molecular Docking

open access: yesMolecules, 2019
A new class of triazinoindole-bearing thiosemicarbazides (1−25) was synthesized and evaluated for α-glucosidase inhibitory potential. All synthesized analogs exhibited excellent inhibitory potential, with IC50 values ranging from 1.30 ± 0.
