A comparative study for optimizing photocatalytic activity of TiO-based composites with ZrO, ZnO, TaO, SnO, FeO, and CuO additives.

Despite the widespread use of titanium dioxide (TiO) in photocatalytic applications, its inherent limitations, such as low efficiency under visible light and rapid recombination of electron-hole pairs, hinder its effectiveness in environmental remediation. This study presents a comparative investigation of TiO-based composites, including TiO/ZrO, ZnO, TaO, SnO, FeO, and CuO, aiming to assess their potential for enhancing photocatalytic applications. Photocatalysis holds promise in environmental remediation, water purification, and energy conversion, with TiO being a prominent photocatalyst.

Consensus-Based Overarching Principles and Recommendations on the Use of Biosimilars in the Treatment of Inflammatory Arthritis in the Gulf Region.

Background: Though biologic agents have significantly improved the treatment of inflammatory arthritis (rheumatoid arthritis, psoriatic arthritis, and axial spondyloarthritis), high costs, stringent regulations, strict reimbursement criteria, and existing patents have limited patient access to treatments. While being highly similar in quality, safety, and efficacy to biologic reference products, biosimilars can reduce the financial burden and prevent underutilization of medication.

Objective: The objective of this initiative was to develop an evidence-based consensus of overarching principles and recommendations aimed at standardizing the use of biosimilars in treating inflammatory arthritis in the Gulf region.

The Role of Extracellular Vesicles in SARS-CoV-2-Induced Acute Kidney Injury: An Overview.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has affected millions worldwide since its outbreak in the winter of 2019. While extensive research has primarily focused on the deleterious respiratory effects of SARS-CoV-2 in recent years, its pan-tropism has become evident. Among the vital organs susceptible to SARS-CoV-2 infection is the kidney.

Imprinted immune abnormalities in liver transplant patients cured of hepatitis C with antiviral drugs.

Chronic HCV infection induces interferon and dysregulates immune responses through inflammation and chronic antigenic stimulation. Antiviral drugs can cure HCV, providing a unique opportunity to examine the immunological restoration that does and does not occur when a chronic viral infection is eradicated. We quantified blood cytokines levels and used mass cytometry to immunophenotype peripheral blood mononuclear cells before and after HCV cure in 2 groups of patients and controls.
