Investigating the relationship between spermogram parameters and sexual desire in infertile men: a cross-sectional study from a tertiary centre in Iran.

Background: Male factor infertility can affect spermatogenesis, sexual desire, and thus the quality of life of couples. The present study was conducted to investigate the relationship between spermogram parameters, and the score of sexual desire in infertile men.

Methods: This cross-sectional study was conducted on 315 infertile men referred to the Avicenna Infertility Center of Tehran (March 2022 to March 2023).

Standardized patients' experience of participating in medical students' education: a qualitative content analysis.

Background: Standardized patients are considered a significant educational method in medical sciences and have been successfully employed for many years. This study was conducted with the aim of explaining the experience of standardized patients participating in the education of medical student.

Method: A qualitative content analysis approach was used.

Effect of selenium nanoparticles-supplemented INRA96 extender on Turkmen stallion sperm quality and lipid peroxidation during storage at 5°C.

Oxidative damage to sperm during cooled storage is a significant issue, and selenium with antioxidant potential could be a solution. Moreover, nano-sized selenium offers more advantages compared to its ionic forms. This research aimed to assess the impact of selenium nanoparticles (SeNPs) supplemented in the INRA96 extender on the quality of Turkmen stallion sperm and lipid peroxidation during 72 h of cooled storage.

Impact assessment of e-trainings in occupational safety and health: a literature review.

Background: Implementing workplace preventive interventions reduces occupational accidents and injuries, as well as the negative consequences of those accidents and injuries. Online occupational safety and health training is one of the most effective preventive interventions. This study aims to present current knowledge on e-training interventions, make recommendations on the flexibility, accessibility, and cost-effectiveness of online training, and identify research gaps and obstacles.

Strategies To Improve the Performance of Hydrogen Storage Systems by Liquefaction Methods: A Comprehensive Review.

The main challenges of liquid hydrogen (H) storage as one of the most promising techniques for large-scale transport and long-term storage include its high specific energy consumption (SEC), low exergy efficiency, high total expenses, and boil-off gas losses. This article reviews different approaches to improving H liquefaction methods, including the implementation of absorption cooling cycles (ACCs), ejector cooling units, liquid nitrogen/liquid natural gas (LNG)/liquid air cold energy recovery, cascade liquefaction processes, mixed refrigerant systems, integration with other structures, optimization algorithms, combined with renewable energy sources, and the pinch strategy. This review discusses the economic, safety, and environmental aspects of various improvement techniques for H liquefaction systems in more detail.
