Bacillus subtilis-derived-exopolysaccharide halts depigmentation and autoimmunity in vitiligo.

Vitiligo has a complex multifactorial etiology involving a T-cell mediated autoimmune response to cutaneous melanocytes. Microbial dysbiosis has been assigned a contributing role in vitiligo etiology. Treating vitiligo can be a challenging task and finding novel treatment approaches is crucial.

Molecular and morphoanatomical characterization of Urocystis heteropogonis sp. nov.: a novel smut fungus infecting Heteropogon contortus.

Background: A new species of smut fungus, Urocystis heteropogonis, was discovered infecting Heteropogon contortus in Shawar Valley, Swat district, Khyber Pakhtunkhwa, Pakistan. The study aimed to characterize this fungus based on its morpho-anatomical and molecular features and clarify its phylogenetic position within the genus Urocystis.

Results: Urocystis heteropogonis was identified as a novel species, distinct from other Urocystis species.

Photocatalytic degradation of methylene blue dye by ZnO nanoparticle thin films, using Sol-gel technique and UV laser irradiation.

The focus of the current work is the study of the effect of the photo-catalytic activity of ZnO nanoparticles. The photocatalytic destruction of methylene blue dye, a common water contaminant, was used to assess the photocatalytic efficiency of the ZnO nanoparticles from its aqueous solution by using ZnO nanoparticles thin film under UV light and laser irradiation. Sol-gel methods prepared ZnO nanoparticle thin films.

A single-center experience in home management of mild and moderate COVID-19 cases.

Introduction: The use of telemedicine for treatment of coronavirus disease 2019 (COVID-19) infection has been effective in lowering the risk of infection and relieving strain on the healthcare system. This study aimed to describe the clinical characteristics of COVID-19 cases, their follow-up, risk factors of disease severity, and predictors of hospital admission while using telemedicine.

Methodology: The study included 611 Egyptian patients with mild and moderate COVID-19 disease.

Optimizing chemically stable chloramphenicol in-situ gel formulations using poloxamer 407 and HPMC through full-factorial design.

The primary goal was to enhance the stability and bioavailability of chloramphenicol for ophthalmic use without compromising patient comfort, such as causing blurry vision. This study employed a 2-level full factorial design to optimize the formulation, exploring different concentrations of poloxamer 407 and HPMC to achieve this objective.
