Background: The involvement of serum ornithine carbamoyltransferase (OCT) in the progression of chronic hepatitis and liver cirrhosis is unclear. Methods: A total 256 patients with chronic hepatitis C and 5 healthy controls were examined. Serum OCT concentrations were measured by enzyme-linked immunosorbent assay. Serum OCT concentrations were compared with serum cytokine and chemokine levels, ...

Intermittent high dose administration of calcitriol or alfacalcidol is effective in suppressing secondary hyperparathyroidism in chronic dialysis patients, however calcaemic action of these vitamin D derivatives is a major obstacle. 22-Oxacalcitriol (OCT) has been reported to have less calcaemic action than calcitriol, while preserving a comparable suppressive effect on parathyroid hormone (PTH...

PURPOSE To present anterior segment optical coherence tomography (AS-OCT) findings of the Kayser-Fleischer (KF) ring in Wilson disease (WD) and to discuss the potential advantages of evaluating the KF ring by AS-OCT. METHODS This is a retrospective case series of 7 patients with WD with KF rings seen in our institute during the study period (August 2015 to June 2016). All patients underwent s...

The RNA polymerases II and III snRNA gene promoters contain an octamer sequence as part of the enhancer and a proximal sequence element (PSE) as part of the core promoter. The octamer and the PSE bind the POU domain activator Oct-1 and the basal transcription factor SNAPc, respectively. Oct-1, but not Oct-1 with a single E7R mutation within the POU domain, binds cooperatively with SNAPc and, in...

The Epstein-Barr virus (EBV) latent-lytic switch is mediated by the BZLF1 immediate-early protein. EBV is normally latent in memory B cells, but cellular factors which promote viral latency specifically in B cells have not been identified. In this report, we demonstrate that the B-cell specific transcription factor, Oct-2, inhibits the function of the viral immediate-early protein, BZLF1, and p...

PURPOSE To evaluate features of optical coherence tomography (OCT) associated with Shaken Baby syndrome (SBS) in an attempt to gain new insight into the pathophysiology of this phenomenon. DESIGN Institutional prospective observational case series. METHODS We report three infants with SBS. Each patient underwent an ophthalmic examination including slit-lamp biomicroscopy, dilated indirect o...

The effects of intracerebroventricular injections of the long-lasting somatostatin analog octreotide (Oct) were studied on sleep and behavior in rats. Pyrogen-free physiological saline and Oct (0.001, 0.01, 0.1 μg) or vehicle were administered at light onset, and the electroencephalogram (EEG), motor activity, and cortical brain temperature were recorded during the 12-h light period. Plasma gro...

Introduction Since 1991, when optical coherence tomography (OCT) was first introduced as a tool for investigation in ophthalmology, OCT has become the mainstay in retinal imaging and, in some situations, has supplanted fundus fluoresce in angiography which is regarded, even today, as the gold standard for investigations in choroidal and retinal disorders. By definition, OCT represents a non-inv...

PURPOSE To evaluate the reproducibility and reliability of Optical Coherence Tomography scans (OCT) obtained using the Time Domain (TD-OCT) StratusTM OCT, and the Spectral Domain (SD-OCT) SpectralisTM and CirrusTM OCT devices before and after manual correction in eyes with either Neovascular (NV-AMD) or Non-Neovascular (NNV-AMD) Age-related Macular Degeneration. METHODS We conducted a prospec...

Joint-aperture optical coherence tomography (JA-OCT) is an angle-resolved OCT method, in which illumination from an active channel is simultaneously probed by several passive channels. JA-OCT increases the collection efficiency and effective sensitivity of the OCT system without increasing the power on the sample. Additionally, JA-OCT provides angular scattering information about the sample in ...
