Urine Pyridinium Cross-Links Determination by Beckman Cross Links Kit [PDF]

open access: yesClinical Chemistry, 1997
Increased understanding of bone turnover has led to the development of several biochemical tests of bone metabolism. Among the biochemical indexes of bone resorption is measurement of urinary excretion of pyridinoline (Pyr) and deoxypyridinoline (Dpyr), molecules that cross-link the collagen chains and are released into the systemic circulation after ...

Collagen cross linking: Current perspectives

open access: yesIndian Journal of Ophthalmology, 2013
Keratoconus is a common ectatic disorder occurring in more than 1 in 1,000 individuals. The condition typically starts in adolescence and early adulthood. It is a disease with an uncertain cause and its progression is unpredictable, but in extreme cases,

Cross-linked informofers

open access: yesNucleic Acids Research, 1979
The proteins of 30S RNP particles containing pre-mRNA (hnRNA) were cross-linked with bifunctional reagents (dimethyl-suberimidate and dimethyl-3,3'-dithiobispropionimidate). Further treatment with 1 or 2 M NaCl dissociates all RNA from protein. However, a significant part of protein particles--informofers being cross-linked survived high salt treatment.

Ion-Cross-Linking-Promoted High-Performance Si/PEDOT:PSS Electrodes: The Importance of Cations’ Ionic Potential and Softness Parameters

open access: yes, 2020
PEDOT:PSS has been studied as a silicon-based binder due to its inherent superior electricity and electrochemical stability. However, it cannot effectively alleviate the huge volume changes of silicon during lithiation/delithiation due to its linear ...
