Idiopathic pulmonary fibrosis (IPF) is a progressive scarring disease of the lung with few effective therapeutic options. Structural remodelling of the extracellular matrix [i.e. collagen cross-linking mediated by the lysyl oxidase (LO) family of enzymes (LOX, LOXL1-4)] might contribute to disease pathogenesis and represent a therapeutic target. This study aimed to further our understanding of ...

The collagens of growth plate and articular cartilage from 5-6 month old commercial pigs were characterised. Growth plate cartilage was found to contain less total collagen than articular cartilage as a proportion of the dry weight. Collagen types I, II, VI, IX and XI are present in both growth plate and articular cartilage whereas type X is found exclusively in growth plate cartilage. Types II...

Pellucid marginal degeneration (PMD) is a rare progressive condition resulting in inferior corneal thinning and astigmatism. Alongside keratoconus and keratoglobus, it is considered one of noninflammatory corneal ectasias. The focus of corneal thinning is greatest inferiorly resulting in diminished visual acuity and overall reduction in visual quality. Traditional methods of treatment or diseas...

Purpose. To report a case with transient anisocoria after corneal collagen cross-linking (CXL). Methods. Case report. Results. A 24-year-old male underwent corneal collagen cross-linking (CXL) in his right eye for keratoconus. At the end of the procedure, the pupil of the treated eye was irregular and dilated, while the pupil of the fellow eye was round, regular, and reactive (anisocoria). The ...

To the Editor: In their article, which was published in the September 2008 issue of the Journal of Refractive Surgery, Krueger et al1 detailed their use of an adapted version of Wollensak et al’s2 corneal collagen cross-linking (CXL) therapy to treat a patient with bullous keratopathy. Although the patient’s symptoms appeared much improved at 6-month follow-up, the safety of such a treatment, i...

Intervertebral discs of the cervical-thoracic region of the spine of BDL mice which are homozygous for the ky gene mutation undergo degeneration. Discs from these mice have a normal collagen content and undergo normal collagen cross linking prior to the appearance of degenerative changes. The major reducible collagen cross-link formed in discs of these mice and in normal CBA strain mice is hydr...

objective: biomaterial technology, when combined with emerging human induced pluripotent stem cell (hipsc) technology, provides a promising strategy for patient-specific tissue engineering. in this study, we have evaluated the physical effects of collagen scaffolds fabricated at various freezing temperatures on the behavior of hipsc-derived neural progenitors (hipsc-nps). in addition, the coati...

Collagen cross-linking is gaining popularity not only for arresting the progression of keratoconus but also other indications including management of corneal infections. In this review article, we analyzed the published literature to understand the level of evidence for its use in corneal ulcer. Photoactivated riboflavin and ultraviolet A light are known to possess antimicrobial properties. The...

BACKGROUND In-vitro and animal studies using EDC cross-linked membranes have shown great resistance to enzymatic digestion as well as low cytotoxicity, and indicated its potential expediency as a barrier membrane for guided bone regeneration (GBR). The purpose of this study was to evaluate the efficacy, biocompatibility and degradation kinetics of a novel 1-ethyl-3-(3-dimethylaminopropyl) carbo...

Abstract In tissue engineering, bioactive materials play an important role, providing structural support, cell regulation and establishing a suitable microenvironment to promote regeneration. As the main component of extracellular matrix, collagen is natural material it has been widely used in scientific research clinical applications. Collagen available from wide range animal origin, can be pr...
