Comparison of clinical characteristics, hospital treatment and outcomes in all four waves of Covid-19 patients at RTEH Muzaffargarh, Pakistan.

Background And Objective: The coronavirus pandemic followed a succession of COVID-19 waves globally, and had a varying pattern of frequency of cases and disease spectrum as each wave came with its distinct viral characteristics. The objective of this study was to compare clinical characteristics, treatments and outcomes of patients admitted with severe COVID -19 pneumonia in all four waves at Recep Tayyip Erdogan Hospital (RTEH).

Methods: A cross sectional retrospective study was conducted at the COVID unit of Recep Tayyip Erdogan Hospital (RTEH), Muzaffargarh, from April 2020 to December 2021.

Advancements in TiO-based photocatalysis for environmental remediation: Strategies for enhancing visible-light-driven activity.

Researchers have focused on efficient techniques for degrading hazardous organic pollutants due to their negative impacts on ecological systems, necessitating immediate remediation. Specifically, TiO-based photocatalysts, a wide-bandgap semiconductor material, have been extensively studied for their application in environmental remediation. However, the extensive band gap energy and speedy reattachment of electron (e) and hole (h) pairs in bare TiO are considered major disadvantages for photocatalysis.

Hard Carbons as Anodes in Sodium-Ion Batteries: Sodium Storage Mechanism and Optimization Strategies.

Sodium-ion batteries (SIBs) are regarded as promising alternatives to lithium-ion batteries (LIBs) in the field of energy, especially in large-scale energy storage systems. Tremendous effort has been put into the electrode research of SIBs, and hard carbon (HC) stands out among the anode materials due to its advantages in cost, resource, industrial processes, and safety. However, different from the application of graphite in LIBs, HC, as a disordered carbon material, leaves more to be completely comprehended about its sodium storage mechanism, and there is still plenty of room for improvement in its capacity, rate performance and cycling performance.

Lucigenin-pyrogallol chemiluminescence for the multiple detection of pyrogallol, cobalt ion, and tyrosinase.

Developing new, cheap, sensitive and selective chemiluminescence (CL) systems with multiple detection properties is still a big challenge for biological and environmental applications. Here, we report a new CL system having multiple detection applications (environmental and biological). The developed lucigenin-pyrogallol system gave an enhancement (190 times) over the conventional lucigenin-HO CL system.

Synthesis of a Novel Electrochemical Probe for the Sensitive and Selective Detection of Biothiols and Its Clinical Applications.

The ability to estimate and quantify biothiols in biological fluids is very significant for attaining a detailed understanding of biothiols-related pathological diseases. Most of the developed methods for biothiols detection are not suitable for this purpose owing to their low sensitivity, poor selectivity, and long experimental procedures. In this study, a novel and simple structure electrochemical probe has been synthesized for the first time for the selective determination of biothiols.

The Reproducibility of the Point of Care Microcirculation (POEM) Score When Used to Assess Critically Ill Patients: A Multicenter Prospective Observational Study.

Background: The current standard of analyzing microcirculatory video microscopy is time-consuming and occurs away from the patient, limiting its clinical utility. Point-of-care assessment with incident dark field (IDF) microscopy, however, may offer greater clinical applicability. We aimed to determine the reproducibility of the Point of Care Microcirculation (POEM) tool when used at the bedside in critically ill patients.

Hydroxylamine-O-sulfonic acid as an efficient coreactant for luminol chemiluminescence for selective and sensitive detection.

Hydroxylamine-O-sulfonic acid, a versatile reagent for organic synthesis, has been explored as an effective coreactant for luminol chemiluminescence. Co(2+) can dramatically enhance the chemiluminescence of this system. The sensitive detection of Co(2+), luminol and HOSA, including highly selective Co(2+) detection, is achieved.
