The importance of size-exclusion characteristics of type I collagen in bonding to dentin matrices
(2013-08-29)
The mineral phase of dentin is located primarily within collagen fibrils. During development, bone or dentin collagen fibrils are formed first and then water within the fibril is replaced with apatite crystallites. Mineralized ...
Collagen fiber reorganization in the rat ventral prostate following androgen deprivation: A possible role for smooth muscle cells
(2000-11-20)
BACKGROUND. Stroma plays an essential role in glandular function in different systems. In the prostate, it is responsible for the development and maintenance of the differentiated state of the epithelium. The marked reduction ...
Obtention and characterization of collagen and chitosan based cements for bone regerneration. Part 1: extraction and characterization of collagen
(2014)
Several cements are used as biomaterials. Biopolymers such as chitosan and collagen exhibit excellent biocompatibility and can be used in the remodeling of bone tissue. The cement must have high mechanical strength and ...
Supraorganized collagen enhances Schwann cell reactivity and organization in vitro
(Associação Brasileira de Divulgação Científica, 2011)
Pentoxifylline modifies three-dimensional collagen lattice model contraction and expression of collagen types I and III by human fibroblasts derived from post-burn hypertrophic scars and from normal skin
(ELSEVIER SCI LTD, 2009)
Fibroblasts are thought to be partially responsible for the persisting contractile forces that result in burn contractures. Using a monolayer cell culture and fibroblast populated collagen lattice (FPCL) three-dimensional ...
QUANTIFICATION OF LEFT VENTRICULAR MYOCARDIAL COLLAGEN SYSTEM IN CHILDREN, YOUNG ADULTS, AND THE ELDERLY
(MEDICINA (BUENOS AIRES)BUENOS AIRES, 2013-08-02)
Studies on the collagen system of the human myocardium are still limited compared to those on small laboratory animals. The aim of this work was to observe the collagen tissue of the myocardium of the human heart as a ...
Collagen-hydroxyapatite films: piezoelectric properties
(Elsevier B.V., 2001-10-03)
In this paper we report a study of the physicochemical, dielectric and piezoelectric properties of anionic collagen and collagen-hydroxyapatite (HA) composites, considering the development of new biomaterials which have ...
Collagens and proteoglycans of the corneal extracellular matrix
(Associação Brasileira de Divulgação Científica, 2003-08-01)
The cornea is a curved and transparent structure that provides the initial focusing of a light image into the eye. It consists of a central stroma that constitutes 90% of the corneal depth, covered anteriorly with epithelium ...
The remodeling of collagen fibers in rats ankles submitted to immobilization and muscle stretch protocol
(SPRINGER HEIDELBERG, 2011)
To evaluate the remodeling of collagen fibers in the articular cartilage of rat ankles, with and without immobilization, after application of muscle stretching protocol. Twenty three Wistar rats were divided into four ...
