Background Systolic myocardial strain is load dependent, but the CMR literature largely disregards effects of myocardial afterload on strain and strain rate. This may reflect well known limitations of conventional myocardial afterload assessment using wall stress analyses, which are based on erroneous assumptions about left ventricular(LV) geometry and/or myocardial material properties. Therefo...
background :older adults with cerebrovascular accident (cva) show evidence of auditory and speech perception problems. in present study, it was examined whether these problems are due to impairments of concurrent auditory segregation procedure which is the basic level of auditory scene analysis and auditory organization in auditory scenes with competing sounds. methods : concurrent auditory seg...
Catestatin (CST), a chromogranin A (CHGA)-derived peptide, is a potent inhibitor of catecholamine release from adrenal chromaffin cells and postganglionic sympathetic axons. We re-sequenced the CST region of CHGA in an Indian population (n = 1010) and detected two amino acid substitution variants: G364S and G367V. Synthesized CST variant peptides (viz. CST-Ser-364 and CST-Val-367) were signific...
Catestatin (CST), an endogenous antihypertensive/antiadrenergic peptide, is a novel regulator of cardiovascular physiology. Here, we report case-control studies in 2 geographically/ethnically distinct Indian populations (n≈4000) that showed association of the naturally-occurring human CST-Gly364Ser variant with increased risk for hypertension (age-adjusted odds ratios: 1.483; P=0.009 and 2.951;...
The corticospinal tract (CST) is generally classified into the crossed lateral CST and the uncrossed anterior CST. No diffusion tensor imaging study for identification of the anterior CST in the human brain has been conducted. Using diffusion tensor imaging, we attempted to identify the anterior CST and investigate the characteristics of the anterior CST in the normal human brain. We recruited ...
Given an undirected graph with edge costs and edge demands, the Capacitated Arc Routing problem (CARP) asks for minimum-cost routes for equal-capacity vehicles so as to satisfy all demands. Constant-factor polynomial-time approximation algorithms were proposed for CARP with triangle inequality, while CARP was claimed to be NP-hard to approximate within any constant factor in general. Correcting...
AIMS Two-dimensional speckle-tracking echocardiography (2D-STE) is limited by its inability to track tissue motion in three dimensions. This is particularly relevant in heart transplant recipients, in whom marked translational motion of the transplanted heart is present. We aimed to compare 3-dimensional (3D)- and 2D-STE-derived strain parameters, and to identify clinical features associated wi...
Mammalian CST (CTC1-STN1-TEN1) is a telomere-associated complex that functions in telomere duplex replication and fill-in synthesis of the telomeric C-strand following telomerase action. CST also facilitates genome-wide replication recovery after HU-induced fork stalling by increasing origin firing. CTC1 and STN1 were originally isolated as a DNA polymerase α stimulatory factor. Here we explore...
BACKGROUND AND AIM Relapse and diabetes mellitus (DM) are major problems for the prognosis of autoimmune pancreatitis (AIP). We examined the prognosis of type 1 AIP after corticosteroid therapy (CST)-induced remission in terms of relapse and DM. METHODS The study enrolled 82 patients diagnosed with type 1 AIP who achieved remission with CST. We retrospectively evaluated the relapse rate in te...
Cortistatin (CST) is a sleep-modulating peptide found exclusively in the brain. Although CST is closely related to somatostatin (SST) and binds to SST receptors, CST has effects on sleep and neuronal activity in cortex and hippocampus that differ from SST. To uncover the cellular mechanisms affected by CST, we studied the electrophysiological postsynaptic effects of CST and assessed its interac...
