Application of in vitro digestion and dialysability procedure for bioavailability evaluation of toxic elements in green leafy vegetables: a realistic health risk assessment by Monte Carlo simulation

Green leafy vegetables (GLVs), which are vital and widely consumed worldwide, require monitoring for contaminants, including toxic elements (TEs). This study measured total concentrations (TC) and bioavailable concentrations (BC) of arsenic (As), cadmium (Cd), lead (Pb), chromium...

Novel cadmium complexes of mixed ligands sulfamethoxazole (SMX) derivatives as potent anticancer agents (MTT assay)

Schiff base of 4-amino-N-(5-methyl-1,2-oxazol-3-yl)benzenesulfonamide was derived from 2-hydoxybenzaldehyde. Cd (II) complexes were ([Cd(SMX)2Cl2] and [Cd(SB)2Cl2]) and its mixed ligand complex, [Cd(S.B)(1,10-Phen)Cl2]. 2H2O were synthesized and characterized on the basis of thei...

InstructDS: An Instruction-Tuned language model with smoothed contrastive confidence decoding for generating patient discharge instructions

Documenting patient discharge instructions is vital for continuity of care, but it also increases provider documentation burden. Large language models now offer an opportunity to support the generation of personalised discharge instructions. This paper introduces InstructDS, an i...

Associations of screen time and physical activity with motor control, mood, and cognitive states in adolescents following acute high-intensity interval training

Excessive screen time and insufficient physical activity are increasingly common among adolescents and have been linked to adverse physical and psychological health outcomes. This school-based cross-sectional study examined associations between sedentary screen time, physical act...

Polynomial Stability of the Timoshenko Beam System with a Fractional Dynamic Boundary Feedback

We investigate the asymptotic behavior of a Timoshenko beam system in which the free end carries a tip mass subject to a restoring spring force and a tempered Caputo fractional damping force with parameter η>0 (the case η=0 is left as an open problem). Using a diffusive state...

Reverse shoulder arthroplasty vs. hemiarthroplasty for proximal humerus fracture: in-hospital outcomes in a national trauma registry

Reverse shoulder arthroplasty (RSA) has rapidly supplanted hemiarthroplasty for acute proximal humerus fracture, driven by superior functional outcomes and lower revision rates. Whether this shift has altered perioperative morbidity at the population level remains poorly characte...

Correlation of maxillary anterior tooth width with facial dimensions in a Yemeni subpopulation: a cross-sectional study

In restorative and prosthetic dentistry, an aesthetic smile is strongly dependent on the harmonious interaction between maxillary anterior teeth and facial proportions. Although similar associations have been studied in various populations, data from Yemeni adults remain limited....

Evaluation of relative safety and therapeutic efficacy of antihyperlipidemic drug regimens used alone or in combination in cardiovascular disease: randomized controlled study

Abstract Background Statin monotherapy is a cornerstone of lipid-lowering therapy for reducing low-density lipoprotein cholesterol (LDL-C) and cardiovascular risk in patients with dyslipidemia. However, many patients at moderate-to-high cardiovascular risk fail to achieve recomme...

Rational design, synthesis, and antimicrobial evaluation of novel 1,2,3-triazole hybrids: structure–activity relationships, molecular docking, and DFT studies

A series of novel 2,4-dichlorophenyl-1,2,3-triazole derivatives and their structural hybrids incorporating chalcone, hydrazone, thio/semicarbazide, carbamate, and pyrazole moieties were rationally designed, synthesized, and characterized. The antimicrobial activity of the synthes...

Ghost (virtual) ileostomy compared with protective ileostomy after low anterior resection for rectal cancer: A GRADE-assessed systematic review and meta-analysis

Protective ileostomy is commonly performed after low anterior resection for rectal cancer to mitigate the clinical consequences of anastomotic leakage; however, it is associated with stoma-related and reversal-related morbidity. Ghost ileostomy has emerged as a selective alternat...

Marginal gap evaluation of zirconia and metal short crowns with varying total occlusal convergence and auxiliary preparation features: an in-vitro study

Marginal adaptation is one of the important factors in determining the long-term success of dental restorations. Despite extensive research, conflicting evidence exists regarding the influence of material type, total occlusal convergence (TOC), and auxiliary preparation features...

Phytochemical profile and in vitro antimicrobial, antiviral, and anticancer activities of Echium angustifolium ethanolic extract

Echium angustifolium is traditionally valued for its therapeutic properties; yet comprehensive studies on its biological activities are limited. Aerial flowering parts were sequentially extracted with solvents of varying polarity. Extracts were analyzed for yield, phytochemical c...

Computational investigation of thermal energy transfer enhancement in nanofluid in the presence of viscous dissipation, Joule heating and yield stress: a local similarity approach
