BACKGROUND Keratoconus may progress to acute corneal hydrops even after cross-linking. In some cases, keratoconus progresses during pregnancy. In this report, we present a case of a patient with increased anterior stromal resistance after cross-linking that would favor nonprogression of keratoconus during pregnancy. CASE PRESENTATION We report that cross-linking is likely to have had a protec...

Laser-induced cross-linking in polymeric semiconductors was utilized to achieve micro- and nano-structuring in thin films. Single- and two-photon cross-linking processes led to the reduction in both the refractive index and thickness of the polymer films. The resultant photonic structures combine the features of both relief- and phase-gratings. Selective cross-linking in polymer blend films bas...

cis- and trans-diamminedichloroplatinum(II) (PDD) produced a DNA cross-linking effect in mouse leukemia L1210 cells, which was demonstrable after subtoxic treatments with the DNA alkaline elution technique. Cross-linking effects developed following treatments with concentrations as low as 1 micron for cis-PDD and 5 micron for trans-PDD, which permitted over 80% survival of colony-forming abilit...

Corneal collagen cross-linking has become the preferred modality of treatment for corneal ectasia since its inception in late 1990s. Numerous studies have demonstrated the safety and efficacy of the conventional protocol. Our understanding of the cross-linking process is ever evolving, with its wide implications in the form of accelerated and pulsed protocols. Newer advancements in technology i...

Cisplatin is a potent anticancer drug, which functions by cross-linking adjacent DNA guanine residues. However within 1 day of injection, 65-98% of the platinum in the blood plasma is protein-bound. It is generally accepted that cisplatin binds to methionine and histidine residues, but what is often underappreciated is that platinum from cisplatin has a 2+ charge and can form up to four bonds. ...

Direct UV cross-linking combined with mass spectrometry (MS) is a powerful tool to identify hitherto non-characterized protein–RNA contact sites in native ribonucleoprotein particles (RNPs) such as the spliceosome. Identification of contact sites after cross-linking is restricted by: (i) the relatively low cross-linking yield and (ii) the amount of starting material available for cross-linking ...
