Perceptions of final-year medical students and interns toward pursuing a career in critical care medicine.
Front Med (Lausanne)
January 2025
College of Medicine, Jazan University, Jazan, Saudi Arabia.
Background: Critical care medicine (CCM) faces challenges in attracting new physicians due to its demanding nature. Understanding medical students' and interns' perceptions of CCM is essential to address physician shortages and improve medical training.
Objective: To evaluate the factors influencing specialty selection and explore perceptions of final-year medical students and interns toward CCM at Jazan University.
Methodological Approaches to Comparative Trend Analyses: The Case of Adolescent Toothbrushing.
Int J Public Health
January 2025
Department of Public Health, University of Copenhagen, Copenhagen, Denmark.
Objectives: Research questions about how and why health trends differ between populations require decisions about data analytic procedure. The objective was to document and compare the information returned from stratified, fixed effect and random effect approaches to data modelling for two prototypical descriptive research questions about comparative trends in toothbrushing.
Methods: Data included five cycles of the Health Behaviour in School-aged Children 2006 to 2022, which provided a sample of 980192 11- to 15- year olds from 35 countries.
Development of a Prandtl-Ishlinskii hysteresis model for a large capacity magnetorheological fluid damper.
J Vib Control
January 2025
Department of Mechanical, Industrial and Aerospace Engineering, Concordia University, Montreal, QC, Canada.
Magnetorheological (MR) fluid (MRF) dampers, serving as fail-safe semi-active devices, exhibit nonlinear hysteresis characteristics, emphasizing the necessity for accurate modeling to formulate effective control strategies in smart systems. This paper introduces a novel stop operator-based Prandtl-Ishlinskii (PI) model, featuring a reduced parameter set (seven), designed to estimate the nonlinear hysteresis properties of a large-scale bypass MRF damper with variable stiffness capabilities under varying applied current. With only seven parameters, the model realizes current, displacement, and rate dependencies.

Assistant professor, Oral and Dental Disease Research Center, Department of Operative Dentistry, Faculty of Dentistry, Zahedan University of Medical Sciences, Zahedan, Iran.
Aim: Tooth sensitivity caused by exposed dentin tubules is a common clinical problem requiring correct treatment methods. Owing to the spread of the COVID-19 virus, it has become common to use different mouthwashes, including 1.5% hydrogen peroxide (HP), before dental procedures.

Ivermectin (IVM) is one of the most widely used antiparasitic drugs worldwide and has become the drug of choice for anthelmintic and tick treatment in beef cattle production. Drugs used in production animals requires a withdrawal period after treatment to avoid residual concentrations above the defined maximun residue level (MRL). The aims of this study were to quantify the residue level of IVM in different muscles of cattle at several different time periods following 1% or 3.
