An Insight into Solventless Reaction Techniques of Monovalent Coinage Metal Complexes

The use of solventless synthetic methods is becoming important in green chemistry, as they allow the production of synthetic organic molecules in a way that is less environmentally harmful and requires less waste, energy, and impact than traditional solvent-mediated methods. In t...

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...

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...

Assessment of anxiety levels and marital relationships among women undergoing infertility treatment: A descriptive observational study

This study aimed to assess anxiety levels and marital relationships among women undergoing infertility treatment. A descriptive observational design was conducted involving 300 infertile women over nine months at Zagazig University Hospital. Data were collected using a Structured...

Public Knowledge, Practices, and Acceptance of Smart Health Technologies Addressing Antibiotic Use and Resistance in Saudi Arabia

Background: Antimicrobial resistance (AMR) remains a major global public health threat, largely driven by inappropriate antibiotic use. Smart health technologies (SHTs), including mobile health applications and digital stewardship tools, offer promising opportunities to improve a...

A sensitive and green spectrofluorimetric method for determination of guanfacine hydrochloride based on NBD-Cl derivatization

A sensitive and environmentally friendly spectrofluorimetric method was developed for the determination of guanfacine in pharmaceutical formulations. The method is based on derivatization of guanfacine with 4-chloro-7-nitrobenzofurazan in alkaline medium to yield a highly fluores...

Comparative analysis of cerium incorporation techniques on Ni/Al2O3 catalysts for methane dry reforming: Surface promotion vs. structural support modification

Two series of 5 wt.% Ni/Al 2 O 3 catalysts incorporating cerium (Ce) at loadings ranging from 1.0 to 3.0 wt.% were prepared by impregnation and subjected to systematic evaluation for the dry reforming of methane (DRM) at 700 °C. The two series were distinguished by the mode of Ce...

FedCogniBand: cognition-aware predictive bandwidth allocation for communication-limited federated learning

Federated Learning (FL) facilitates collaborative model training among dispersed clients while safeguarding data privacy; yet, its practical implementation is significantly hindered by substantial uplink bandwidth restrictions and notable data heterogeneity. Even though there hav...
