Biomimetic collagen composite matrix-hydroxyapatite scaffold induce bone regeneration in critical size cranial defects

Materials & Design, 2023
Although biomimetic scaffolds have been constructed to repair critical-size bone defects, the creation of composite scaffolds that can mimic the anisotropy of natural bone remains a major challenge.

Collagens [PDF]

Cell and Tissue Research, 2009
The collagens represent a family of trimeric extracellular matrix molecules used by cells for structural integrity and other functions. The three alpha chains that form the triple helical part of the molecule are composed of repeating peptide triplets of glycine-X-Y.

Ventricular fibrillation immediately after the treatment of Graves’ disease coexisting with atypical angina and long QT syndrome: a case report

Thyroid Research, 2022
Background Palpitations due to Graves’ disease are often caused by supraventricular arrhythmia. However, in rare cases, the background of coronary artery disease, genetic abnormalities, or channel abnormalities can cause ventricular fibrillation, which ...

Hypercalcemia associated with dysgerminoma and elevation of calcitriol: A case report and review of the literature

SAGE Open Medical Case Reports, 2022
We report on the case of a patient with dysgerminoma, a rare germ cell tumor, which showed hypercalcemia with an elevation of 1α,25-dihydroxycholecalciferol (calcitriol). A 27-year-old nulliparous woman presented with hypercalcemia during the examination

Pathological and immunological differences of arterial thrombi and wall caused by three different periodontal bacterial injections in rat models and proposals on the pathogeneses of vascular diseases

Clinical and Experimental Dental Research, 2021
Objectives Periodontal bacteria that have been studied show a strong connection to various vascular diseases. Among the many kinds of periodontal bacteria, Porphyromonas gingivalis (Pg) is well examined in the general aspects and in a rat model. However,

Fungal-Modified Lignin-Enhanced Physicochemical Properties of Collagen-Based Composite Films

Journal of Fungi, 2022
Renewable and biodegradable materials have attracted broad attention as alternatives to existing conventional plastics, which have caused serious environmental problems. Collagen is a potential material for developing versatile film due to its biosafety,

Collagen propeptides as indicators of collagen assembly [PDF]

Acta Orthopaedica Scandinavica, 1995
It is old knowledge that bones are for about 70% made up of calcium salts and for about 30% of collagen. More specifically, almost all of the collagen in the collagen fibres of mineralized tissues is type I collagen, while most of the other almost 20 genetically distinct collagen types are essentially proteins of soft tissues.

Mechanical properties of collagen fibrils [PDF]

, 2007
The formation of collagen fibers from staggered subfibrils still lacks a universally accepted model. Determining the mechanical properties of single collagen fibrils ( diameter 50 - 200 nm) provides new insights into collagen structure. In this work, the
