Hemostat has been a crucial focus since human body is unable to control massive blood loss, and collagen proves to be an effective hemostat in previous studies. In this study, collagen was isolated from the mesoglea of jellyfish Rhopilema esculentum Kishinouye and its hemostatic property was studied. The yields of acid-soluble collagen (ASC) and pepsin-soluble (PSC) were 0.12% and 0.28% respect...
Glutaraldehyde (GA) fixation of bioprosthetic tissue is a well adapted technique, with commercial products on the market for almost 40 years. Amine groups present in tissue react with GA to form different types of cross-links. An estimation of the degree of cross-linking of the tissue can be obtained by measuring the concentration of residual amine groups, which is frequently carried out with t...
UNLABELLED The purpose of this study was to determine whether exercise and/or acetaminophen (APAP) alter collagen and cross-linking in the rat gastrocnemius muscle, soleus muscle, and heart. Male Wistar rats (n = 50; 8 wk old) were divided into placebo (PLA) or APAP groups and sedentary (SED) or exercised (RUN) groups. APAP (200 mg/kg) was administered daily by oral gavage. Exercised groups ran...
This paper describes the isolation from reduced collagen of two new amino acids believed to be involved, in their non-reduced form, as intermolecular cross-links stabilizing the collagen fibre. The reduction of intact collagen fibrils with tritiated sodium borohydride was found to stabilize the aldehyde-mediated cross-links to acid hydrolysis and thus allowed their location and isolation from a...
AIMS Diastolic dysfunction is central to the development of heart failure. To date, there is no effective treatment and only limited understanding of its molecular basis. Recently, we showed that the transmembrane proteoglycan syndecan-4 increases in the left ventricle after pressure overload in mice and man, and that syndecan-4 via calcineurin/nuclear factor of activated T-cells (NFAT) promote...
OBJECTIVE To assess the relation between type I collagen degradation and the duration of rheumatoid arthritis (RA). METHODS The serum concentrations of cross linked carboxyterminal telopeptide of type I collagen (ICTP) measured earlier in a community based series (90 patients) and a hospital based series (59 patients) were re-evaluated with reference to the duration of RA. RESULTS The serum...
