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...
متن کاملMechanical properties of skinned single muscle fibers crosslinked with glutaraldehyde.
It was shown earlier (Mikawa 1979; Prochniewicz 1979) that crosslinking of thin filaments in vitro by glutaraldehyde can "'freeze'" their structure either in the activated (in the presence of Ca"-ions) or depressed (in the absence of C a t ions) state. This treatment does not inhibit the ability of actin to bind to myosin heads and to activate myosin ATPase (Lehrer 1981; Prochniewicz-Nakayama a...

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 اولEffects of gamma irradiation on mechanical behavior and calcification of glutaraldehyde-fixed bovine pericardium.
OBJECTIVE To evaluate the effect of gamma irradiation on glutaraldehyde-fixed bovine pericardium. METHOD Glutaraldehyde-fixed bovine pericardium was exposed to gamma radiation (doses from 0 to 10000 Gy). Six samples from each of nine groups were evaluated by optic microscopy, and shrinking and mechanical tests and the denaturation temperature was determined. Additionally, they were subcutaneo...
متن کاملAnticalcification effects of decellularization, solvent, and detoxification treatment for genipin and glutaraldehyde fixation of bovine pericardium.
OBJECTIVE Calcification plays a major role in the failure of bioprosthetic and other tissue heart valve substitutes. The objective of this study was to evaluate the anticalcification effect of decellularization and detoxification in glutaraldehyde (GA)/genipin- and solvent-fixed bovine pericardium using a rabbit intramuscular model which is effective for assessing calcification in bioprosthetic...
