P-54: Evaluation of The Acute and Chronic Effects of Different Gold Nanoparticle Doses on Sperm Parameters and Chromatin Structure in Mice

Background The solid and colloidal particles in the range of 1-100 nm are called nanoparticles. Recently, one of the most important metal nanoparticles, with wide usage is gold nanoparticle. Based on the previous studies, gold nanoparticles have spermatotoxic effects and can destroy sperm motility. The aim of present study is the effect of gold nanoparticles on chromatin quality and sperm param...

Wh-Questions\' Expression in Persian-speaking Children: A Comparison Between Spontaneous and Elicited Probes

Objectives: Studies have shown that most children before the age of 5 are capable to comprehend and express wh-questions in daily conversations. This study aimed at comparing the ability of wh-questions’ production in 4- to 6-year-old children in spontaneous and elicited conditions. Methods: In this descriptive-analytic study, 4- to 6-year-old Persian-speaking children (N = 72) were selected r...
