Correction: TGF-β Prevents Phosphate-Induced Osteogenesis through Inhibition of BMP and Wnt/β-Catenin Pathways
BACKGROUND Transforming growth factor-β (TGF-β) is a key cytokine during differentiation of mesenchymal stem cells (MSC) into vascular smooth muscle cells (VSMC). High phosphate induces a phenotypic transformation of vascular smooth muscle cells (VSMC) into osteogenic-like cells. This study was aimed to evaluate signaling pathways involved during VSMC differentiation of MSC in presence or not o...
متن کاملA Highly Diastereoselective and Enantioselective Phase-Transfer Catalyzed Epoxidation of β-Trifluoromethyl-β,β-disubstituted Enones with H2O2
Trifluoromethylated organic compounds, especially chiral quaternary alcohols bearing trifluoromethyl group are of important intermediates in drugs, agrochemicals and etc.An efficient epoxidation of β-CF3-β,β-disubstituted unsaturated ketones (6) has been developed with environmental benign hydrogen peroxide as the oxidant and F5-substituted chiral qua...
متن کاملAspartyl-(asparaginyl) β-Hydroxylase, Hypoxia-Inducible Factor-1α and Notch Cross-Talk in Regulating Neuronal Motility
Aspartyl-(Asparginyl)-β-Hydroxylase (AAH) promotes cell motility by hydroxylating Notch. Insulin and insulin-like growth factor, type 1 (IGF-I) stimulate AAH through Erk MAPK and phosphoinositol-3-kinase-Akt (PI3K-Akt). However, hypoxia/oxidative stress may also regulate AAH. Hypoxia inducible factor-1 alpha (HIF-1α) regulates cell migration, signals through Notch, and is regulated by hypoxia/o...
متن کاملسنتز ترکیبات β - آمینو الکلها
β- آمینو الکلها کاربرد وسیعی در زمینه های صنعتی، بیولوژیکی و دارویی دارند. واکنش افزایش هسته دوستی آمین ها به اپوکسید ها یکی از روشهای موثر برای سنتز این دسته از ترکیبات می باشد که معمولاً به وسیلهء اسیدهای لوئیس از قبیل zncl2، ساماریوم یدید ، آلومینا ، sn(otf)2 و ... انجام می شوند. از آنجاییکه این روشها دارای معایبی از قبیل زمان واکنش طولانی، شرایط سخت واکنش، راندمان پایین، استفاده از حلال سمی ...
15 صفحه اول3D Powder Printed Bioglass and β-Tricalcium Phosphate Bone Scaffolds
The use of both bioglass (BG) and β tricalcium phosphate (β-TCP) for bone replacement applications has been studied extensively due to the materials' high biocompatibility and ability to resorb when implanted in the body. 3D printing has been explored as a fast and versatile technique for the fabrication of porous bone scaffolds. This project investigates the effects of using different combinat...
