Introduction: Congenital hypothyroidism (CH) is one of the most common preventable causes of mental retardation. Its worldwide incidence is estimated to be one in 2500-5500 births. Assessment of thyroid gland in neonates is critical. The aims of this study were to demonstrate the incidence of CH in neonates born in Yazd province, Iran in 1389 (2010) and compare the results with other reported s...

Here, metal nanoparticles were synthesized by chemical reduction of the corresponding metal salts in the presence of chitosan polymer. Binary and ternary metallic-chitosan Pt-Fe-CH, Pt-Co-CH and Pt-Fe-Co-CH nanocomposites were prepared. Transmission electron microscopy images and UV–Vis spectra of the nanocomposites confirmed the presence of the metal nanoparticles. The electrocatalytic activit...

this study discusses the effect of complexes of chitosan grafted polyethylenimine(ch-pei) with plasmid dna on viability of mesenchymal stem cells(mscs) derived from human marrow. ch-pei/pdna nanoparticles were synthesized through the complex coacervation method using pires plasmid containing green fluorescent protein (gfp) gene. to confirm the complexation, samples were run through an agarose g...

cystic hygroma (ch) in the cervical region presents as a challenge to the anesthetist. the anaesthetic difficulties are usually associated with ch because of tumor extension into the mouth, airway management, thoracic extension, hemorrhage, involvement of pretracheal region, post operative respiratory obstruction and coexisting anomalies (down syndromes, turner syndromes and congenital cardiac ...

Objective(s): The present study aimed to prepare polycaprolactone (PCL) scaffolds with high porosity and pore interconnectivity, in order to copy the microstructure of natural bones using the thermally induced phase separation (TIPS) technique. Materials and Methods: The scaffolds were coated with chitosan (CH), bioactive glass (BG), and gelatin nanoparticles (GEL NPs) and assessed using ...

background: hypothyroidism (ht), a relatively common condition among general population is associated with lipid profile abnormalities. the present study was designed to determine the contributive role of ht in the development of hypercholesterolemia (hch). methods: one hundred thirty six consecutive patients with ht and 272 euthyroid controls entered the study. serum total cholesterol (ch) lev...
