Adjunctive sildenafil enhances paroxetine response in lifelong premature ejaculation: A randomized double-blind trial with exploratory SLC6A4 genotype analyses

Objectives To test whether adjunctive sildenafil improves the response to paroxetine in lifelong premature ejaculation (PE) and to explore whether SLC6A4 5-HTTLPR genotype modifies the effect.Methods In this randomized, double-blind trial, 80 men with lifelong PE were assigned 1:...

A new fractional-order cascade controller structure for frequency regulation of interconnected renewable-dominant power systems

Abstract Ensuring reliable frequency regulation in contemporary multi-area interconnected power systems has become increasingly demanding due to changes in consumption patterns, the massive integration of intermittent renewable energy sources (RESs), the integration of distribute...

Hydraulic conductivity reduction can be decoupled from plant available water and can influence nitrogen leaching in amended sandy soils

Abstract Improvements in sandy-soil hydraulic behavior are often inferred from reduced permeability rather than from direct gains in plant-available water (AW). This study quantified the extent to which amendment-induced reductions in saturated hydraulic conductivity (K s ) corre...

The Impact of Exposure of Aloe-Vera Gel Extract to Low-Level Laser Radiation as a New Therapeutics Against Streptozotocin-Induced Diabetic Rats

Abstract Background: Diabetes mellitus (DM), often just called diabetes, is a condition in which the person's body does not produce enough, or does not properly respond to insulin, or non-insulin production. Streptozotocin (STZ) is a medical agent that could use in experimental a...

CFD-Driven Passive Cooling and Renewable Retrofits for Nearly Net-Zero University Buildings in a Hot–Humid Climate

Achieving net-zero energy and zero-emission buildings is a critical pathway toward decarbonizing the built environment, particularly in cooling-dominated regions where operational energy demand remains exceptionally high. Existing university buildings in hot–humid climates face s...

Geometric morphometric analyses of intragenus (Campylomormyrus) and intergenus hybrids in mormyrid fish

Abstract Natural hybrids within the weakly electric mormyrid fish genus Campylomormyrus have not been documented in the wild. However, recent advances have enabled the artificial production of both intragenus ( Campylomormyrus ) and intergenus ( Campylomormyrus and Gnathonemus )...

Sero-epidemiological survey of Toxoplasma gondii in water buffalo (Bubalus bubalis) and domestic pig (Sus scrofa domesticus) across upper and lower Egypt

Toxoplasma gondii ( T. gondii ) is a globally prevalent protozoan parasite affecting warm-blooded species, including humans. In Egypt, serological surveys have been conducted in several livestock; however, studies on species such as buffalo and pigs remain scarce. This study aime...

Coordinated Control of Supercapacitors and Hybrid Electric Vehicles for Frequency Regulation in Renewable Power Grids Considering Communication Delays

Integrating renewable energy sources into modern power grids enhances sustainability but reduces the inherent inertia provided by synchronous generators, leading to larger frequency fluctuations and degraded dynamic stability. To address this issue, this paper proposes an advance...

Sustainable use of phosphogypsum to enhance sandy soils fertility and wheat yield in arid environments

Abstract Purpose Sandy soils in arid regions have low fertility, poor structural stability, and limited water‐holding capacity. This study evaluated phosphogypsum (PG) as a soil amendment for improving sandy‐soil quality and wheat productivity under arid conditions. Methods A fie...

Modeling and experimental validation of an indirect active hybrid solar dryer for mint leaves: Coupled thermal and moisture-transfer analysis

A mathematical model was developed and experimentally validated to predict the thermal performance and drying behavior of an indirect active solar dryer (IAHSD) for mint leaves. The distinctive contribution of the proposed approach is its integration of solar-energy input, auxili...

Environmental sustainability and thermodynamic evaluation of a solar dryer with zigzag airflow during henna leaf drying

Abstract This study developed and evaluated a solar dryer with a zigzag airflow pathway for drying henna leaves under Egyptian climatic conditions. The system was designed to improve air‐product contact in tray drying by directing heated air alternately above and below the drying...

Ventricular Tachycardia Ablation in Nonischemic Cardiomyopathy: Is Pulsed Field Ablation the Next Paradigm Shift?

Ventricular tachycardia ablation in nonischemic cardiomyopathy remains limited by high recurrence rates despite advances in catheter-based techniques. In nonischemic cardiomyopathy, the arrhythmogenic substrate is often heterogeneous and may involve intramural or epicardial myoca...

Monitoring pedestrian walking dynamics under environmental and policy influences in urban spaces

Abstract Understanding how environmental conditions and policy interventions jointly shape pedestrian mobility is essential for designing resilient, adaptive, and human-centered urban spaces. This study presents a computer-vision framework that extracts pedestrian trajectories fr...
