BACKGROUND The thymidine phosphorylase (TP) enzyme has several tumor-promoting functions. The aim of this study was to explore TP gene expression in relation to clinical and histopathological data obtained from patients with stage III colorectal cancer. METHODS AND RESULTS TP gene expression was analyzed by real-time quantitative PCR in tumor and mucosa samples from 254 patients. TP gene expr...

The present study aimed to test the incremental validity of Time Perspective (TP) scales in predicting satisfaction with life and mood, over and above the Big Five personality traits. It also investigated whether the new TP construct of Future Negative perspective contributed to prediction of these outcomes. Participants (N = 265) completed four measures: Satisfaction With Life Scale (SWLS), UW...

OBJECTIVE To assess the feasibility of 12-lead electrocardiographic (ECG) measures such as P wave dispersion (PWd), QT interval, QT dispersion (QTd), Tp-e interval, Tp-e/QT and Tp-e/QTc ratio in predicting poor outcome in patients diagnosed with sepsis in pediatric intensive care unit (PICU). METHODS Ninety-three patients diagnosed with sepsis, severe sepsis or septic shock and 103 age- and s...

Thymidine phosphorylase (TP) is an angiogenic factor that plays a pivotal role in tumor angiogenesis. Various kinds of solid tumors express TP and high TP activity is correlated with microvessel density. We have previously reported that TP enhances interleukin-8 (IL-8) expression in KB human epidermoid carcinoma cells. In this study, TP was shown ...

BACKGROUND Total pancreatectomy (TP) is not more beneficial than less aggressive resection techniques for the treatment of pancreatic neoplasms and is associated with high morbidity and mortality. However, with advances in surgical techniques and glycemic monitoring, and the development of synthetic insulin and pancreatic enzymes for postoperative treatment, TP has been increasingly indicated. ...

Background & Aims: Recent studies have shown that thrombocytopenia (TP) is associated with poor outcomes in patients with pneumonia, burns, and H1N1 influenza. The aim of this study is to determine the impact of platelet count trends and TP on mortality in intensive care unit (ICU) patients. Materials & Methods: TP was defined as <150,000 platelets/ml. In this study, 300 patients who had been ...

Bacteriophage Φ29 genome consists of a linear double-stranded DNA with a terminal protein (TP) covalently linked to each 5' end (TP-DNA) that together with a specific sequence constitutes the replication origins. To initiate replication, the DNA polymerase forms a heterodimer with a free TP that recognizes the origins and initiates replication using as primer the hydroxyl group of TP residue Se...

Reverse sequence screening for syphilis (RSSS) (screening with treponemal tests, followed by confirmation with nontreponemal tests) has been increasingly adopted. CDC recommends confirmation of discordant results (reactive EIA/CIA and nonreactive nontreponemal test) with Treponema pallidum particle agglutination assay (TP-PA). We characterized sera with discordant results from RSSS with Archite...

in some quality control applications, the quality of a process or a product is described by the relationship between a response variable and one or more explanatory variables, called a profile. moreover, in most practical applications, the qualitative characteristic of a product/service is vague, uncertain and linguistic and cannot be precisely stated. the purpose of this paper is to propose a ...

BACKGROUND Thymidine phosphorylase (TP) is identical with platelet-derived endothelial cell growth factor (PD-ECGF) which promotes angiogenesis. The aim of this study was to evaluate the cytosol activity of TP in tumor samples from patients with endometrial cancer. METHODS The activity of TP was measured by the spectrophotometric method in the cytosol of endometrial tumor samples from 43 pati...
