The dual effect of calcium on aromatization by cultured human trophoblast.

Cytotoxicity of Triple Antibiotic Paste and Calcium Hydroxide against Cultured Human Dental Pulp Fibroblasts

  Objective: In necrotic immature teeth, intra canal medicaments such as triple antibiotic paste (TAP) and calcium hydroxide (CH) are used for root canal disinfection and regeneration treatment. However, the effect of these medicaments on dental pulp fibroblasts has yet to be known. This study aimed to assess the cytotoxicity of CH and TAP against cultured human dental pulp fibroblasts (HDPFs) ...

Human Trophoblast Progenitor Cells Express and Release Angiogenic Factors

Trophoblast stem cells develop from polar trophoectoderm and give rise to the cells that generate the placenta. Trophoblast cells are responsible for the uterinal invasion and vascular remodeling during the implantation of the embryo. However this knowledge is not yet to be confirmed for trophoblast progenitor cells (TPCs). In this study, we aimed to demonstrate that human TPCs (hTPCs) express ...

Expression and Distribution of Calcium-Binding Protein S100P in Human Placenta during Pregnancy

Synthesis and Effects of Novel Dihydropyridines as Dual Calcium Channel Blocker and Angiotensin Antagonist on Isolated Rat Aorta

Objective(s) Four novel losartan analogues 5a-d were synthesized by connecting a dihydropyridine nucleus to imidazole ring. The effects of 5a and 5b on angiotensin receptors (AT') and L-type calcium channels were investigated on isolated rat aorta. Materials and Methods Aortic rings were pre-contracted with 1 pM Angiotensin II or 80 mM KCl and relaxant effects of losartan, nifedipine, 5a and...

Effect of different concentrations of leukemia inhibitory factor on gene expression of vascular endothelial growth factor-A in trophoblast Tumor Cell Line

Background: Several studies have shown that leukemia inhibitory factor (LIF) is one of the most important cytokinesparticipating in the process of embryo implantation and pregnancy, while, the role of this factor on vascular endothelialfactor-A (VEGF-A), as one of the most important angiogenic factor, has not been fully investigated yet. The aimof this study was to evaluate th...
