BACKGROUND The clinical efficiency and functional outcomes of supracricoid partial laryngectomy (SCPL) with cricothyroidopexy (CTP) were compared with those of the traditional SCPL with cricohyoidoepiglottopexy (CHEP) in treating laryngeal squamous carcinoma involving anterior vocal commissure (AVC). METHODS From January 2000 to June 2009, 50 patients diagnosed with early- or intermediate-sta...

Background: Liver cirrhosis is one of the most significant causes death in many regions worldwide. This study aimed to assess correlation hemostatic and endocrine parameters with Child-Turcotte-Pugh (CTP) scoring patients non-alcoholic liver cirrhosis. Materials Methods: included 59 monitored for a gastroenterology clinic from January 2018 February 2019. The subjects were grouped according CTP ...

CTP synthetases catalyze the last step of pyrimidine biosynthesis and provide the sole de novo source of cytosine-containing nucleotides. As a central regulatory hub, they are regulated by ribonucleotide and enzyme concentration through ATP and UTP substrate availability, CTP product inhibition, GTP allosteric modification, and quaternary structural changes including the formation of CTP-inhibi...

OBJECTIVE The purpose of this study was to investigate the efficiency of computed tomography perfusion (CTP), contrast-enhanced computed tomography (CECT) and 18F-fluoro-2-deoxy-D-glucose (18F-FDG) positron-emission tomography (PET/CT) in the diagnosis of esophageal cancer. SUBJECTS AND METHODS This prospective study consisted of 33 patients with pathologically confirmed esophageal cancer, 2 ...

CTP synthetase is an essential enzyme that generates theCTP required for the synthesis of nucleic acids and membrane phospholipids. In this study, we examined the phosphorylation of the human CTPS1-encoded CTP synthetase 1 by protein kinase A. CTP synthetase 1 was expressed and purified from a Saccharomyces cerevisiae ura7 ura8 double mutant that lacks CTP synthetase activity. Using purified CT...

BACKGROUND AND PURPOSE CT perfusion (CTP) is a more readily accessible method for evaluation of cerebral perfusion than single-photon emission CT (SPECT). We assessed whether there is any resting or drug-challenged CTP parameter correlating with cerebrovascular reserve (CVR) obtained by SPECT in Moyamoya patients. MATERIALS AND METHODS Normalized baseline CTP parameters and their percentage c...

OBJECTIVES To examine the relationship between preoperative serum pyridinoline cross-linked carboxy-terminal telopeptide of type I collagen (I-CTP) levels and postoperative distant metastasis in patients with non-small-cell lung cancer (NSCLC). METHODS We retrospectively reviewed 143 patients in whom preoperative serum I-CTP level was measured from January 2006 to March 2011, including 91 mal...

BACKGROUND Familial Mediterranean fever (FMF) is a chronic, recurrent auto-inflammatory disease characterised by self-terminating attacks of fever and sterile polyserositis. The main cause of death in auto-inflammatory diseases is cardiovascular events. Additionally, auto-inflammatory diseases have potential effects on the myocardial repolarisation parameters, including the T-wave peak-to-end (...

OBJECTIVE To investigate the diagnostic performance of coronary computed tomography angiography (CCTA), stress dual-energy computed tomography perfusion (DE-CTP), stress perfusion single-photon emission computed tomography (SPECT), and the combinations of CCTA with myocardial perfusion imaging (CCTA + DE-CTP and CCTA + SPECT) for identifying coronary artery stenosis that causes myocardial hypop...

AIM Computed tomography perfusion (CTP) has recently been used to identify regions of potential ischemia due to cerebral vasospasm, and CTP parameters are able to quantitatively evaluate brain parenchymal perfusion. We performed a meta-analysis as an update of a previous paper published in 2010 and aimed at evaluating the diagnostic accuracy of CTP and CTP parameters for vasospasm after aneurys...
