Characterization of biomodified dentin matrices for potential preventive and reparative therapies

TL;DR: The highest degree of agent-dentin interaction was observed with GSE, which exhibited the highest denaturation temperature, regardless of the agent concentration, and the tensile strength properties of GD-biomodified dentin matrices were affected by dentin tubule orientation, most likely due to the orientation of the collagen fibrils.

Enhanced bleomycin-induced pulmonary damage in mice lacking extracellular superoxide dismutase.
TL;DR: 2-Pyrrolidone levels in the lung hydrolysates from ec-sod null mice were increased at both 7 and 14 d post-bleomycin treatment as compared to wild-type mice, indicating EC-SOD can inhibit oxidative fragmentation of proteins in this specific model of oxidative stress.

TL;DR: The concomitant increase in AGEs and alteration of tensile properties of cartilage after ribose treatment suggest that aging-associated changes in A GEs have functional consequences for this tissue.

TL;DR: Findings from the heterozygous oim bone suggest that increasing the quantity of healthy collagen in these bones helps to recover toughness at the multiple length scales, and demonstrates how modifications at the bone molecular level have ramifications at larger length scales affecting the overall mechanical integrity of the bone.

Arterial fibrous proteins in cynomolgus monkeys after atherogenic and regression diets.
M L Armstrong,M B Megan +1 more
TL;DR: In this article, the authors measured five arterial beds in adult cynomolgus monkeys after administration of atherogenic and regression regimens and found that fibrous proteins are lost from the arterial wall during a regression regimen.

The determination of hydroxyproline.
Robert E. Neuman,Milan A. Logan +1 more
TL;DR: A short and simple calorimetric method is here described that is applicable to the determination of hydroxyproline in hydrolysates of 40 to 100 y of collagen with a reproducibility of f2 per cent and an accuracy of f1 per cent as judged by recovery of hydroXYproline from elastin hydrolysate and from an amino acid mixture simulating collagen.

TL;DR: Stetten (1949) suggested that free hydroxyproline was not an intermediate in collagen biosynthesis and that hydroxylation of the proline residues occurred at the protein or peptide stage.
