Background: The present study sought to evaluate the prophylactic effect of bethametazone on sulfur mustard (SM)-induced ocular morphometric damage in the rabbit eye.
Methods: Twenty five healthy New Zealand white rabbits were divided into 4 groups of normal (not exposed to SM or solution), solution (exposed to solution), SM (exposed to SM), and prophylactic bethametazone (received eye solution of bethametazone then exposed to SM solution; then treated for 2 weeks). On the day 14 after exposure, five-micron sections were stained with haematoxylin and eosin for light microscopy evaluation. The ocular morphometric characteristics in the study groups were compared to determine the prophylactic effects of the bethametazone.
Results: Bethamethazone could protect eyes from SM effect by means of decrease in changes in number of Keratocyte in 10000 μm(2), thickness of cornea (μm), thickness of corneal epithelium (μm), number of meibomian gland's cells in 2500 μm(2), thickness of palpebral conjuctival epithelium (μm), thickness of epithelial of palpebral skin (μm), number of epithelial layers of palpebral skin, and number of goblet cells in conjunctival sac in 1000 μm.
Conclusions: Bethametazone may have a prophylactic effect on the early lesions of the eye of the rabbit due to SM exposure.

The molecular basis for the liquid-liquid phase separation (LLPS) behavior of various biomolecular components in the cell is the formation of multivalent and low-affinity interactions. When the content of these components exceeds a certain critical concentration, the molecules will spontaneously coalesce to form a new liquid phase; i.e.

Hydrogen spillover-based binary (HSBB) system has attracted significant attention in alkaline hydrogen evolution reaction (HER). Accelerating hydrogen spillover in the HSBB system is crucial for the HER activity. Herein, a highly efficient HSBB system is developed by anchoring nano-Ru on oxygen vacancy (Vo) rich amorphous/crystal ZrO.

Unlabelled: Hemozoin (HZ) is a waste product of hemoglobin digestion by and has been implicated in several pathological processes, including inflammation, oxidative stress, endothelial dysfunction, and immune dysregulation. Studying the effects of HZ on the human placenta is essential to understanding the impact of malaria infection during pregnancy. The present study explored the impact of HZ produced by and β-hematin, referred to here as natural HZ (nHZ) and synthetic HZ (sHZ), respectively, on human placental explants exposed .

The conservation of soil, a finite natural resource, demands effective measures. Within this context, the instability of soil masses on steep slopes poses significant risks to human life and environmental infrastructure, highlighting the need for developing erosion control strategies rooted in soil bioengineering principles. The objective of this study was to investigate the mechanical properties of fibers subjected to biodegradation and treated with sodium hydroxide (NaOH) for geotextile manufacturing.

Introduction: Substance use disorders, particularly alcohol use disorders, represent a significant public health problem, with adolescents particularly vulnerable to their adverse effects. This study examined the possible anxiolytic and antidepressant effects of biotin, a crucial vitamin for brain function, in attenuating the behavioral and neurobiological changes associated with alcohol withdrawal in adolescent rats.
Materials And Methods: Sixty male Sprague-Dawley rats were exposed to a 20% ethanol solution for 21 days, followed by a 21-day drug-free period to assess long-term behavioral and physiological changes.
