The aim of this study was to investigate the neurotoxicity of silver nanoparticles in the adult rat hippocampus. Materials and Methods:12 male Wistar rats were randomly divided into two experimental and contro...
[ 7 ] - Lectin Histochemical Study of Vasculogenesis During Rat Pituitary Morphogenesis
Objective(s) The aim of this study was to investigate glycoconjugates distribution patterns as well as their changes during the course of pituitary portal vasculogenesis and angiogenesis. Materials and Methods Formalin fixed paraffin sections of 10 to 20 days of Sprague Dawly rat fetuses were processed for histochemical studies using four different horseradish peroxidase (HRP) conjugated lec...
[ 8 ] - مطالعه توزیع و تغییرات قندهای انتهایی گلیکوکانژوگیت‌ها در طی تکامل فولیکول مو در رت با استفاده از فن لکتین هیستوشیمیایی
Background & Aims : Hair follicle morphogenesis is controlled by complex reprocical ectodermal–mesenchymal interactions regulated by molecular mechanisms. In addition, glycoconjugates are known to be important for molecular interactions during developmental processes. The aim of this research was to study glcoconjugate terminal sugars distributions and changes during rat hair follicle morph...
