Detrimental effects of cerium oxide nanoparticles on testis, sperm parameters quality, and in vitro fertilization in mice: An experimental study.

Background: Cerium oxide nanoparticles (CeO NPs) as an important nanomaterial have a wide range of applications in many fields and human beings' exposure to this nanomaterial is unavoidable. The effects of CeO NPs on the male reproductive system are controversial.

Objective: To determine the effects of the administration of CeO NPs on the testis tissue, sperm parameters, and in vitro fertilization (IVF) in mice.

Evaluation of the risk factors associated with emergency department boarding: A retrospective cross-sectional study.

Purpose: Boarding is a common problem in the emergency department (ED) and is associated with poor health care and outcome. Imam Khomeini Hospital is the main healthcare center in Urmia, a metropolis in the northwest of Iran. Due to the overcrowding and high patient load, we aim to characterize the rate, cause and consequence of boarding in the ED of this center.

The effects of exposure to fluoxetine during lactation on testicular tissue and sperm parameters in mice offspring.

Fluoxetine is a selective serotonin reuptake inhibitor is commonly prescribed to treat maternal depression in pregnancy and lactation. This study aimed to investigate the effects of maternal exposure to fluoxetine via lactation on testicular tissue, sperm parameters including count, motility, viability, and normal morphology and testicular oxidative stress status in male mice offspring. Ten mice dams were divided into control and experimental groups.

The protective effect of vitamin C on phenylhydrazine-induced hemolytic anemia on sperm quality and in-vitro embryo development in mice.

Background: Phenylhydrazine (PHZ) induced anemia and was shown to have harmful effects on the male reproductive system.

Objective: To investigate the protective effect of vitamin C (Vit C) on sperm parameters quality, in vitro fertilization potential and embryonic development in a mouse model of hemolytic anemia induced by PHZ.

Materials And Methods: Thirty-two NMRI adult male mice ( = 8/each) were randomly classified into four groups.
