Routing protocol in Wireless Sensor Network (WSN) poses lots of challenges in today’s research world. In most of the applications we need to maintain reliability, efficiency, scalability. In this context we have evaluated the performance of Collection Tree Protocol (CTP) for WSN applications and examined that CTP performs poorly in case of data delivery most of the times due to path inconsisten...

BACKGROUND AND PURPOSE The incidence and significance of perfusion abnormalities on brain imaging in patients with lacunar infarct are controversial. We studied the diagnostic yield of CTP and the type of perfusion abnormalities in patients presenting with a lacunar syndrome and in those with MR imaging-confirmed lacunar infarcts. MATERIALS AND METHODS A cohort of 33 patients with lacunar syn...

Background Coronary computed tomography angiography (CTA) enables accurate anatomic evaluation of coronary artery stenosis, however lacking information about hemodynamical significance. The aim of this study was to evaluate 128-slice myocardial CT perfusion (CTP) imaging with adenosine stress using a high-pitch mode, in comparison with cardiac magnetic resonance imaging (CMR). Methods and Resul...

BACKGROUND AND PURPOSE To establish intraobserver and interobserver variability for regional measurement of CT brain perfusion (CTP) and to determine whether reproducibility can be improved by calculating perfusion ratios. MATERIALS AND METHODS CTP images were acquired in 20 patients with unilateral symptomatic carotid artery stenosis (CAS). We manually drew regions of interest (ROIs) in the ...

INTRODUCTION Collagen peptides have been reported to possess various biological activities for various cell types. The purposes of this study were, first, to examine the therapeutic effects of collagen tripeptide (Ctp) in rabbit osteoarthritis and, second, to explore a synergetic effect with hyaluronan (HA). METHODS Osteoarthritis was induced by anterior cruciate ligament transection of the r...

Noninvasive vascular imaging techniques, such as computed tomographic angiography (CTA) and CT perfusion (CTP), are becoming increasingly important in evaluation and triage of patients with acute ischemic stroke (AIS). In fact, recently published American Heart Association and American Stroke Association guidelines strongly recommend using CTA in evaluation of patients with AIS secondary to lar...

The essential zinc finger protein ASCIZ (also known as ATMIN, ZNF822) plays critical roles during lung organogenesis and B cell development in mice, where it regulates the expression of dynein light chain (DYNLL1/LC8), but its functions in other species including invertebrates are largely unknown. Here we report the identification of the Drosophila ortholog of ASCIZ (dASCIZ) and show that loss ...

OBJECTIVE To systematically evaluate and compare the diagnostic accuracy of CT perfusion (CTP), non-enhanced computed tomography (NCCT) and computed tomography angiography (CTA) in detecting acute ischemic stroke. METHODS We searched seven databases and screened the reference lists of the included studies. The risk of bias in the study quality was assessed using QUADASII. We produced paired f...

CTP synthase is an essential enzyme that plays a key role in energy metabolism. Several independent studies have demonstrated that CTP synthase can form an evolutionarily conserved subcellular structure termed cytoophidium. In budding yeast, there are two isoforms of CTP synthase and both isoforms localize in cytoophidium. However, little is known about the distribution of CTP synthase isoforms...
