A one-pot preparation of the 2,2'-dibromo-1,1'-bisheteroarenes 3a-d from bromo-heteroarenes utilizing the sequence of the base-catalyzed halogen dance (BCHD) reaction and CuCl(2)-promoted oxidative coupling of the in situ formed alpha-lithio-beta-halo-heteroarenes 2a-d provides a convenient access to precursors for the preparation...

Increases in apoptosis, caspase activity and expression of p53 and bax, and the transition between two types of mitochondrion-rich cells, in the gills of the climbing perch, Anabas testudineus, during a progressive acclimation from freshwater to seawater.

Front Physiol. 2013 Jun 07;4:135. doi: 10.3389/fphys.2013.00135. eCollection 2013.

This study aimed to test the hypothesis that branchial osmoregulatory acclimation involved increased apoptosis and replacement of mitochdonrion-rich cells (MRCs) in the climbing perch, Anabas testudineus, during a progressive acclimation from freshwater to seawater. A significant increase in branchial...

Transl Vis Sci Technol. 2018 Dec 17;7(6):24. doi: 10.1167/tvst.7.6.24. eCollection 2018 Nov.

PURPOSE: The activation of microglia, the primary innate immune cell resident in the retina, produces inflammatory mediators, which underlie changes in diabetic retinopathy including increased vascular permeability. This study evaluates the safety and efficacy of dextromethorphan, a drug capable...

PURPOSE: In macula-wide analyses, spectral-domain (SD) optical coherence tomography (OCT) features including drusen volume, hyperreflective foci, and OCT-reflective drusen substructures independently predict geographic atrophy (GA) onset secondary to age-related macular degeneration (AMD). We sought to identify SD OCT features...
