MicroRNAs (miRNAs) are an abundant class of noncoding RNAs that are believed to be important in many biological processes through regulation of gene expression. Little is known of their function in tooth morphogenesis and differentiation. MicroRNA-214 (miR-214), encoded by the polycistronic Dnm30os gene, is highly expressed during development of molar tooth germ and was selected as a target for...

amelogenesis imperfectas (ais) are clinically and genetically heterogeneous conditions characterized by a wide range of clinical features. these abnormalities of enamel formation are categorized into three main groups, hypoplastic, hypomaturation and hypocalcified with different modes of inheritance such as autosomal recessive (ar), autosomal dominant (ad) and x-lined recessive (xlr). in spite ...

Extracellular matrix proteins are considered to play essential roles in controlling the nucleation, growth, and organization of hydroxyapatite crystals during enamel formation. The effects of amelogenin and the 32-kDa enamelin proteins on apatite nucleation were investigated by a steady-state gel diffusion device containing 10% gelatin gels loaded with 0, 0.75%, and 1.5% (w/w) native porcine am...

In this study, we analyzed the phenotype, clinical characteristics and presence of mutations in the enamelin gene ENAM in five Colombian families with autosomal dominant amelogenesis imperfecta (ADAI). 22 individuals (15 affected and seven unaffected) belonging to five Colombian families with ADAI and eight individuals (three affected and five unaffected) belonging to three Colombian families w...

Background: Since antibiotic resistance of uropathogens has gradually been rising, knowledge of antimicrobial resistance pattern of Escherichia coli (Esch. coli), the predominant pathogen of urinary tract infection (UTI), is important in selecting empirical antimicrobial therapy. Objectives: To find out the common organisms causing UTI with their antimicrobial susceptibility pattern in Enam Med...
