Effect of freeze-drying on the mechanical, physical and morphological properties of glutaraldehyde-treated bovine pericardium: evaluation of freeze-dried treated bovine pericardium properties.
PURPOSE Biomaterials have been widely used in the field of regenerative medicine. Bovine pericardium tissue has been successfully used as a bioprosthetic material in manufacturing heart valves, but studies concerning the tissue are ongoing in order to improve its storage, preservation and transportation. This article provides an overview of the characteristics of bovine pericardium tissue chemi...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولGlutaraldehyde-treated bovine pericardium: effects of lyophilization on cytotoxicity and residual aldehydes.
This work assesses the effect of lyophilization on the cytotoxicity and residual aldehyde concentration of glutaraldehyde-treated and lyophilized bovine pericardium (group A), comparing it to conventional glutaraldehyde-treated bovine pericardium (group B). Cytotoxicity was measured by incubating a pericardium sample from each group in saline and assessing the eluant's influence on cellular gro...
متن کاملEffect of freeze-drying and gamma irradiation on biomechanical properties of bovine pericardium Abstract Freeze-drying and gamma irradiation are the techniques widely use in tissue banking for preservation and sterilization of tissue grafts
Freeze-drying and gamma irradiation are the techniques widely use in tissue banking for preservation and sterilization of tissue grafts respectively. However, the effect of these techniques on biomechanical properties of bovine pericardium is poorly known. A total of 300 strips of bovine pericardium each measured 4 cm 1 cm were used in this study to evaluate the effect of freeze-drying on biome...
متن کاملAlkaline phosphatase activity of glutaraldehyde-treated bovine pericardium used in bioprosthetic cardiac valves.
Bioprosthetic valves fail frequently because of pathological mineralization, a process that begins in cell remnants of the glutaraldehyde (GLUT) fixed tissue. Other pathological cardiovascular calcification and physiological mineralization in skeletal/dental tissues are both largely initiated in cell-derived membranous structures (often called "matrix vesicles"), and the enzyme alkaline phospha...
