The difference between residual monomer dentin bonding HEMA and UDMA with acetone and ethanol solvent after binding to type I collagen

open access: yesDental Journal, 2018
Background: In caries and non-caries lesions involving dentine, it is necessary to provide dentine-bonding material to help improve retention between the composite resin and the tooth surface.

A quantitative study of the relationship between the distribution of different types of collagen and the mechanical behavior of rabbit medial collateral ligaments. [PDF]

open access: yesPLoS ONE, 2014
The mechanical properties of ligaments are key contributors to the stability and function of musculoskeletal joints. Ligaments are generally composed of ground substance, collagen (mainly type I and III collagen), and minimal elastin fibers.

Application of Collagen I and IV in Bioengineering Transparent Ocular Tissues

open access: yesFrontiers in Surgery, 2021
Collagens represent a major group of structural proteins expressed in different tissues and display distinct and variable properties. Whilst collagens are non-transparent in the skin, they confer transparency in the cornea and crystalline lens of the eye.

Influence of collagen type II and nucleus pulposus cells on aggregation and differentiation of adipose tissue-derived stem cells [PDF]

open access: yes, 2008
Tissue microenvironment plays a critical role in guiding local stem cell differentiation. Within the intervertebral disc, collagen type II and nucleus pulposus (NP) cells are two major components.

Aging and the Impact of Solar Ultraviolet Radiation on the Expression of Type I and Type VI Collagen

open access: yesCosmetics, 2023
Both endogenous and exogenous factors cause skin aging. This study aimed to compare the differential expressions of collagen type I (COL I) and collagen type VI (COL VI) in skins with biological aging and photoaging.

Immunohistochemical localization of collagen types I and VI in human skin wounds [PDF]

open access: yes, 1996
A total of 74 human skin wounds were investigated and collagen types I and VI were localized in the wound area by immunohistochemistry. Collagen type I appeared in the form of ramifying string-like structures after approximately 5–6 days, but positive ...

Chondrocyte Migration to Fibronectin, Type I Collagen, and Type II Collagen.

open access: yesCell Structure and Function, 1997
It is well known that cellular interactions, such as cell adhesion, migration, invasion, between cells and the extracellular matrix are mediated by the integrin family of cell surface receptors. Chondrocytes are surrounded by an abundant extracellular matrix, but there is less information on the cellular receptors which interact with this matrix.

Thermal (In)Stability of Type I Collagen Fibrils [PDF]

open access: yesPhysical Review Letters, 2009
We measured Young's modulus at temperatures ranging from 20 to 100 ^{\circ}$C for a collagen fibril taken from rat's tendon. The hydration change under heating and the damping decrement were measured as well. At physiological temperatures $25-45^{\circ}$C Young's modulus decreases, which can be interpreted as instability of collagen.

Genotype-phenotype correlation study in 364 osteogenesis imperfecta Italian patients [PDF]

open access: yes, 2019
Osteogenesis imperfecta (OI) is a rare genetic disorder of the connective tissue and 90% of cases are due to dominant mutations in COL1A1 and COL1A2 genes.

Effects of paeonol on proliferation and collagen synthesis of rat cardiac fibroblasts induced by aldosterone

open access: yesBangladesh Journal of Pharmacology, 2021
The aim of this study was to explore the possible molecular mechanisms of paeonol in preventing ventricular remodeling. The cell viability of neonatal rat cardiac fibroblasts was detected by the method of MTT. RT-PCR and Western blot were used to measure
