We performed a paternity test in a case of incest between brother and sister. DNA from blood samples of the alleged parents and their two children was obtained with Chelex DNA extraction method and quantified with Applied Biosystems QuantiBlot quantitation kit. Polymerase chain reaction (PCR) amplification of DNA samples was performed with AmpFlSTR SGM Plus PCR amplification kit and GenePrint P...

Previously, we have shown that serine-16 phosphorylation in native full-length porcine amelogenin (P173) and the Leucine-Rich Amelogenin Peptide (LRAP(+P)), an alternative amelogenin splice product, affects protein assembly and mineralization in vitro. Notably, P173 and LRAP(+P) stabilize amorphous calcium phosphate (ACP) and inhibit hydroxyapatite (HA) formation, while non-phosphorylated count...

Leucine-Rich Amelogenin Protein (LRAP) is a member of the amelogenin family of biomineralization proteins, proteins which play a critical role in enamel formation. Recent studies have revealed the structure and orientation of the N- and C-terminus of LRAP bound to hydroxyapatite (HAP), a surface used as an analog of enamel. The structure of one region, K24 to S28, was found to be sensitive to p...

An unresolved problem in tooth enamel studies has been to analyze simultaneously and with sufficient spatial resolution both mineral and organic phases in their three dimensional (3D) organization in a given specimen. This study aims to address this need using high-resolution imaging to analyze the 3D structural organization of the enamel matrix, especially amelogenin, in relation to forming en...

This review presents a discourse on challenges in understanding and imitating the process of amelogenesis in vitro on the molecular scale. In light of the analysis of imitation of the growth of dental enamel, it also impends on the prospects and potential drawbacks of the biomimetic approach in general. As the formation of enamel proceeds with the protein matrix guiding the crystal growth, whil...

background : amelogenins are the major components of enamel matrix proteins. enamel matrix derivatives (emd) can be used in periodontal diseases to regenerate periodontal tissues. the main aim of this study was to evaluate ex-pression of full-length functional recombinant human amelogenin (rham) in iranian lizard leishmania (i.l.l.) as an alternative eukaryotic expression system. methods : huma...

objective(s):to determine the fetal discernment in suspected cases of sex linked recessive disease in the first trimester of pregnancy. materials and methods: after collection of 100 chorionic villi samples, the dnas were extracted and baby gender was determined. meanwhile, after increasing the sensitivity, the system was able to detect the sex of each cell which was obtained by biopsy. results...
