Halide perovskites exhibit beneficial opto-electronic properties (e.g. long carrier lifetimes and low defect densities), and their dynamic structural instabilities and anharmonic thermal fluctuations are directly implicated in these properties. In th

On the role of DMSO-O(lone pair)⋯π(arene), DMSO-S(lone pair)⋯π(arene) and SO⋯π(arene) interactions in the crystal structures of dimethyl sulphoxide (DMSO) solvates

Autor: Julio Zukerman-Schpector, Edward R. T. Tiekink

Publikováno v: CrystEngComm. 16:6398-6407

Dimethyl sulphoxide (DMSO) molecules in their all-organic solvates were shown to interact with arene rings of organic molecules via DMSO-O(lone pair)⋯π(arene) or DMSO-S(lone pair)⋯π(arene) interactions in approximately 5–6% of their crystal s

Efficacy of Moxifloxacin Plus Nitazoxanide Based Sequential Triple Therapy for Eradication of Helicobacter Pylori Infection

Autor: Shabir A Shiekh, Zafar I Kawoosa, Zafar A Wani, Shafat S Lone, Feroz A Wani

Publikováno v: JK Science, Vol 23, Iss 1 (2021)

Background: Helicobacter pylori eradication rates has been suboptimal despite multiple-drug regimens owing to increasing drug resistance. Purpose: To assess the efficacy of a novel sequential therapy based on moxifloxacin and nitazoxanide for eradica

Publikováno v: International Journal of Advances in Medicine. 10:201-206

Background: Colonic polyps are the abnormal growths from the colonic mucosa, usually benign but there is a definite though a small risk for cancerous transformation. Scarce data about this condition is available from Northern India. In this study we
