The Quality of Life of Urban Omani People During the COVID-19 Pandemic in A'Seeb Wilayat: A Cross-sectional Study.

Objectives: COVID-19 is an emergent disease with significant global concern, which might have a negative effect on quality of life. This study aimed to determine the impact of the COVID-19 pandemic on the quality of life of people (with or without COVID-19) attending primary health centers in A'Seeb Wilayat in Muscat, Oman.

Methods: This cross-sectional study was conducted in four randomly selected primary health centers in A'Seeb Wilayat from 17 July 2021 to 31 January 2022.

Coronavirus Disease 2019 Infection in Children With Sickle Cell Disease: Case Series From Oman.

Background: In March 2020, WHO announced Coronavirus Disease 2019 (COVID-19) outbreak a global pandemic. During this pandemic, patients with sickle cell disease (SCD) have been placed in the "high-risk" category of the population. Although there are numerous publications describing COVID-19 in adult patients, pediatric data are still limited.

Chemiluminescence determination of chlorpheniramine using tris(1,10-phenanthroline)-ruthenium(II) peroxydisulphate system and sequential injection analysis.

A sequential injection (SI) method was developed for the determination of chlorpheniramine (CPA), based on the reaction of this drug with tris(1,10-phenanthroline)-ruthenium(II) [Ru(phen)(3)(2+)] and peroxydisulphate (S(2)O(8)(2-)) in the presence of light. The instrumental set-up utilized a syringe pump and a multiposition valve to aspirate the reagents [Ru(phen)(3)(2+) and S(2)O(8)(2-)] and a peristaltic pump to propel the sample. The experimental conditions affecting the chemiluminescence reaction were systematically optimized, using the univariate approach.

Enhancement of the chemiluminescence of penicillamine and ephedrine after derivatization with aldehydes using tris(bipyridyl)ruthenium(II) peroxydisulfate system and its analytical application.

A novel sequential injection (SI) method was developed for the determination of penicillamine (PA) and ephedrine (EP) based on the reaction of these drugs with tris(bipyridyl)ruthenium(II) (Ru(bpy)(3)(2+)) and peroxydisulfate (S(2)O(8)(2-)) in the presence of light. Derivatization of PA and EP with aldehydes has resulted in a significant enhancement of the chemiluminescence emission signal by at least 25 times for PA and 12 times for EP, leading to better sensitivities and lower detection limits for both drugs. The instrumental setup utilized a syringe pump and a multiposition valve to aspirate the reagents, (Ru(bpy)(3)(2+) and S(2)O(8)(2-)), and a peristaltic pump to propel the sample.
