Modifications of the locomotor system in habitually quadrupedal humans.

The acquisition of habitual bipedal locomotion, which resulted in numerous modifications of the skeleton was a crucial step in hominid evolution. However, our understanding of the inherited skeletal modifications versus those acquired while learning to walk remains limited. We here present data derived from X-rays and CT scans of quadrupedal adult humans and compare the morphology of the vertebral column, pelvis and femur to that of a bipedal brother.

Calcium hypochlorite on mouse embryonic fibroblast cells (NIH3T3) in vitro cytotoxicity and genotoxicity: MTT and comet assay.

Antimicrobial irrigation solutions are widely used under clinical settings. Their effect on dental tissue is a subject of recent research, which aims for a safer irrigant for clinical use. In this regard, here our goal was to evaluate the cytotoxicity and the genotoxicity of calcium hypochlorite (Ca(OCl)) solution, along with NaOCl, on Mouse embryonic fibroblast cells (NIH3T3).

Estrogen receptor alpha (Esr1) regulates aromatase (Cyp19a1) expression in the mouse brain.

Objectives: Local estrogen production in the brain regulates critical functions including neuronal development, gonadotropin secretion and sexual behavior. In the mouse brain, a 36 kb distal promoter (l.f) regulates the Cyp19a1 gene that encodes aromatase, the key enzyme for estrogen biosynthesis.

Gene mutations in chronic kidney disease patients with secondary hyperparathyroidism and Sagliker syndrome.

Sagliker syndrome (SS) develops particularly before puberty while chronic kidney disease (CKD) reaches stage 3 with overt secondary hyperparathyroidism. We conducted screening for mutations in all the 13 exons of GNAS1 gene, all 3 exons of FGF23, and all 18 exons in FGFR3 genes in 23 patients. In 73.

Genetic polymorphisms of estrogen receptor alpha and catechol-O-methyltransferase genes in Turkish patients with familial prostate carcinoma.

Objectives: Estrogen is one of the most crucial hormones participating in the proliferation and carcinogenesis of the prostate glands. Genetic polymorphisms in the estrogen metabolism pathway might be involved in the risk of prostate carcinoma development. We evaluated the association between genetic polymorphisms in estrogen receptor alpha (ESR1) and catechol-O-methyltransferase (COMT) genes and the risk of developing familial prostate carcinoma.
