مهندسی بافت یک روش بیولوژیک مناسب برای جایگزینی بافت غایب یا از دست رفته میباشد. با توجه به اینکه کمبود بافت در بیماران شکاف کام و لب، جراحی این ناهنجاری را پیچیده می کند لذا هدف از این مطالعه ارزیابی میزان فعالیت و تشکیل عضله اربیکولاریس اریس پس از استفاده از داربست ماتریکس خارج سلولی عضله و سلولهای بنیادی مزانشیمی در ترمیم نقص شکاف لب در رت بود. روش کار: در این مطالعه ی حیوانی، تعداد 40 ر...
We propose a new model for the emergence of blood capillary networks. assimilate tissue and extra cellular matrix as porous medium, using Darcy's law describing both interstitial fluid flows. Oxygen obeys convection-diffusion-reaction equation advection by blood, diffusion consumption tissue. Discrete agents named elements modelling groups endothelial cells are created or deleted according to d...
Bone marrow microenvironment contains cellular and acellular compartments. The cellular compartment includes hematopoietic stem cells, mesenchymal stem cells and some other stromal cell types, while the acellular compartment is composed of scaffold proteins known as the extra cellular matrix. Direct cell-cell contact as well as cytokines secreted by mesenchymal stem cells during coculture of he...
CONTEXT Hepatitis B (HBV) and hepatitis C virus (HCV) possess well-known oncogenic properties and may promote carcinogenesis in liver. However antigens and replicative sequences of HBV/HCV have been also detected in different extra-hepatic tissues, including the pancreas. Although epidemiological studies and meta-analyses have recently suggested that HBV/HCV may be also risk factors for pancrea...
The hydrophilic, conducting, biocompatible and porous scaffolds were designed using poly(2-hydroxy ethyl methacrylate)-co-poly(N-isopropylacrylamide)-co-poly(ε-caprolactone) (P(HEMA-b-NIPAAm-b-CL))/polyaniline (PANI) for the osteoblast applications. To this end, the PHEMA and P(HEMA-b-NIPAAm) were synthesized via reversible addition of fragmentation chain transfer (RAFT) polymerization, and in ...
Objective: Echium amoenum Fisch. & C.A. Mey. is used for the treatment of various diseases in traditional medicine. This plant is a major source of anthocyanins with beneficial cardiovascular properties such as anti-atherosclerotic and antihypertensive effects. In the present study, the protective and antioxidant effects of anthocyanin-rich E. amoenum extract were evaluated on human vascular en...
