The epidemiology of substance use disorders in Saudi Arabia: findings from the Saudi national mental health survey.

Background: Substance use disorders (SUDs), encompassing alcohol (AUDs) and drug use disorders (DUDs), are significant global public health concerns. While SUDs are well-documented worldwide, data on their prevalence and impact in Saudi Arabia remain scarce. This study investigates the epidemiology and burden of SUDs in Saudi Arabia using data from the Saudi National Mental Health Survey (SNMHS).

One-pot, Four-component Synthesis, Molecular Docking and Pharmacokinetic Studies of Tetra-substituted Imidazole Derivatives as Potential Mushroom Tyrosinase Inhibitors.

Introduction: An efficient and four-component one-pot facile synthesis of tetra-substituted imidazole is achieved by cyclo-condensation reaction of benzil with subsequent successive substitution of aromatic aldehydes, ester substituted amine and ammonium acetate via refluxing the mixture for almost two hours at 140°C.

Method: The ending point of the understudy reaction was examined by TLC after regular intervals. Synthesized 1,2,4-tetrasubstituted imidazoles were characterized by physical data and the structural features were analyzed using spectroscopic techniques such as FTIR, NMR and elemental analysis.

Exploring the nutritional composition and quality parameters of natural honey from diverse melliferous flora.

Natural honey is enriched with essential and beneficial nutrients. This study aimed to investigate the melliferous flora microscopic techniques and assess the biochemical properties of honey. Flavonoid and phenolic contents in honey samples were analyzed via colorimetric and Folin-Ciocalteu methods and the alpha-amylase, reducing power, and minerals using Pull's and spectroscopy methods.

ToRCH pathogens-induced histopathological changes in placental tissues and associated post obstetric complications.

Background: Maternal infections caused by the ToRCH complex, comprising Toxoplasma gondii (T.gondii), Rubella Virus (RV), Cytomegalovirus (CMV), and Herpes Simplex Virus (HSV), are significant contributors to Bad Obstetric History (BOH). These infections can vertically transmit through the placental barrier, leading to complications in fetal development.
