BACKGROUND The model for end-stage liver disease (MELD) scoring system has become the prevailing criteria for organ allocation in liver transplantation. However, it is not clear if the predictive accuracy of MELD is equally homogeneous in different distribution of MELD score blocks. METHODS We investigated 472 cirrhotic patients (mean MELD, 14.3+/-5.5), and compared the predictive accuracy of...
Background and Objective: Esophageal variceal bleeding is associated with a high mortality rate and expensive hospitalization costs. By diagnosing predicting factors of rebleeding at admission, and proper course of action, we can minimize the rates of mortality rebleeding. The aim of this study was to determine the predicting factors of rebleeding in patients hospitalized because of variceal he...
Background & Aims : Risk factors for r ebleeding following acute variceal haemorrhage are incompletely understood. The aim of this study was to determine the predictor validity of model for end stage liver disease (MELD) score and Child-Turcotte-Pugh (CTP) in acute variceal bleeding and rebleeding. Method : The study included 92 cirrhotic patients of Imam Khomeini hospital. The predictive c...
آشکارسازی پتانسیل‌های وابسته به رخداد، یک پیش‌نیاز مهم در سیستم‌های واسط مغز و کامپیوتر (BCI) مبتنی بر ERP است. برای افزایش درصد صحت طبقه‌بندی در این سیستم‌ها، از روش‌های فیلتر‌ینگ مختلفی استفاده می‌شود تا نرخ سیگنال به نویز بهبود یابد و در نتیجه تشخیص و طبقه‌بندی پتانسیل‌های وابسته به رخداد آسان شود. پیش از این، عملکرد فیلترهای الگوی مکانی مشترک (CSP) و الگوی زمانی مشترک (CTP) که به‌ترتیب فیلت...
Collagen tripeptide (CTP) is a functional food material with several biological effects such as improving dry skin and wound and bone fracture healing. This study focused on the anti-photoaging effects of CTP on a hairless mouse model. To evaluate the effects of CTP on UVB-induced skin wrinkle formation in vivo, the hairless mice were exposed to UVB radiation with oral administration of CTP for...
CTP synthetase (EC 6.3.4.2, UTP:ammonia ligase (ADP-forming)) is an essential enzyme in all organisms; it generates the CTP required for the synthesis of nucleic acids and membrane phospholipids. In this work we showed that the human CTP synthetase genes, CTPS1 and CTPS2, were functional in Saccharomyces cerevisiae and complemented the lethal phenotype of the ura7Delta ura8Delta mutant lacking ...
OBJECTIVES To evaluate how well patients with coronary stents accept combined coronary computed tomography angiography (CTA) and myocardial CT perfusion (CTP) compared with conventional coronary angiography (CCA). BACKGROUND While combined CTA and CTP may improve diagnostic accuracy compared with CTA alone, patient acceptance of CTA/CTP remains to be defined. METHODS A total of 90 patients ...
