Biological Activities and In Silico Molecular Docking of an Aqueous Extract of Nigella sativa L. Seeds: A Focus on Antioxidant, Cytotoxic, and Diuretic Effects

Background: Nigella sativa L. is a medicinal plant widely recognized for its diverse pharmacological properties. This study aimed to evaluate the antioxidant, diuretic, and cytotoxic effects of an aqueous seed extract and its effects on selected biochemical parameters in rats. Th...

Markovian Dynamics Associated with d-Orthogonal Polynomials and Generalized Birth and Death Processes in Multiple-Life Insurance

We construct upward skip-free continuous-time Markov chains from finite-band recurrences associated with d-orthogonal polynomial systems. In the alternating-sign chamber, the recurrence yields an order-d generalized birth–death generator with one upward and at most d downward jum...

Epigenetic Regulation of Host Immunity During Parasitic Infections: Mechanisms, Immune Evasion, and Therapeutic Opportunities

INTRODUCTION: Parasitic infections remain a major global health challenge involving complex interactions between pathogens and host immunity. Emerging evidence indicates that epigenetic mechanisms, including DNA methylation, histone modifications, chromatin remodeling, and non-co...

Optimizing genotype and nitrogen management for improved yield and agronomic efficiency in dry direct seeded rice under temperate ecology

Rice production through conventional transplanting is becoming increasingly difficult because of limited water resources and labor shortages. Dry direct-seeded rice (DSR) offers a practical alternative with lower water and labor requirements. However, the success of DSR depends o...

Developing Growth Reference Curves for Jordanian Children and Adolescents: A Comparative Analysis with WHO Growth Standards and References

Background: Growth standards and growth references serve different purposes. The WHO Child Growth Standards for ages 0–5 years describe growth under specified optimal conditions, whereas the WHO 5–19-year curves are a reference reconstructed from historical NCHS data. This study...

Evaluating the association between emotional intelligence, perceived support, and academic performance among nursing graduate students: a descriptive-correlational study

Nursing graduate education in Pakistan is increasingly recognized as pivotal for producing competent clinical leaders, educators, and researchers. However, the rigorous academic and clinical demands place immense psychological pressure on students, potentially compromising their...

Reliability and Profit Analysis of a Five-Subsystem Hybrid Series-Parallel System with Gumbel–Hougaard Copula Repair, Cold Standby, and Dual Environmental Failure Rates

This work offers a reliability framework for a five-subsystem hybrid series-parallel system representing smart factory monitoring infrastructure under heat and vibration stressors. A central programmable logic controller (1-out-of-1), pressure and temperature sensors (2-out-of-5)...

Exploring the journey towards evidence-based clinical decision-making among emergency care personnel

Emergency care personnel play a critical role in providing timely and effective care, where the use of evidence-based practices is essential for informed clinical decision-making. This study explored the extent to which emergency care personnel incorporate evidence-based practice...

Molecular identification and statistical optimization of endo-α-amylase production by Bacillus licheniformis KeR9 isolated from potato roots for maltooligosaccharide synthesis

A starch-degrading bacterial strain (KeR9) isolated from potato root tissues was identified through whole-genome sequencing using average nucleotide identity (ANI) and DNA-DNA hybridization (DDH) as Bacillus licheniformis . This strain with enzymatic production potential was then...

A fuzzy graph-based Kulli–Basava descriptor for isomer discrimination and physicochemical property prediction

Abstract In this paper, a generalized fuzzy Kulli-Basava index ( $$FKB^{*}_1$$ ) of fuzzy graphs is introduced, which is an extension of the classical index, by introducing a fuzzy vertex degree, fuzzy edge membership value, and fuzzy sum of the degree of incident vertices. Unlik...

Characterization and phylogenetic analysis of the mitochondrial 12S rRNA gene sequences of Aphaniops dispar

The Arabian killifish ( Aphaniops dispar ) is a resilient freshwater species capable of surviving extreme environments, making it a valuable model for studying evolutionary adaptation in challenging environments. This study provides baseline genetic information of A. dispar popul...

Electrochemical detection of gallic acid in commercial beverages empowered by the use of paper-based tool to collect and analyze
