BACKGROUND Mechanical unloading of the failing human heart induces profound cardiac changes resulting in the reversal of a distorted structure and function. In this process, cardiomyocytes break down unneeded proteins and replace those with new ones. The specificity of protein degradation via the ubiquitin proteasome system is regulated by ubiquitin(More)
In this work, using multiple, dissimilar physico-chemical techniques, we demonstrate that the Escherichia coli RNA polymerase core enzyme obtained through a classic purification procedure forms stable (α(2)ββ'ω)(2) complexes in the presence or absence of short DNA probes. Multiple control experiments indicate that this self-association is unlikely to be(More)
PURPOSE To evaluate the change in trabecular-iris circumference volume (TICV) after laser peripheral iridotomy (LPI) in primary angle closure (PAC) spectrum eyes. PATIENTS AND METHODS Forty-two chronic PAC spectrum eyes from 24 patients were enrolled. Eyes with anterior chamber abnormalities affecting angle measurement were excluded. Intraocular pressure,(More)
PURPOSE To evaluate the normal aging effects on trabecular meshwork (TM) parameters using Fourier domain anterior segment optical coherence tomography (ASOCT) images. PATIENTS AND METHODS One eye from 45 participants with open angles was imaged. Two independent readers measured TM area, TM length, and area and length of the TM interface shadow from 3 age(More)
In this work, we describe RapA-dependent polyadenylation of model RNA substrates and endogenous, RNA polymerase-associated nucleic acid fragments. We demonstrate that the Escherichia coli RNA polymerase obtained through the classic purification procedure carries endogenous RNA oligonucleotides, which, in the presence of ATP, are polyriboadenylated in a(More)
