In this article, long-term data, statistical analysis, and spatial interpolation method were applied to the analyses of the spatial and temporal changes of total nitrogen (TN) and total phosphorus (TP) in Dianshan Lake. We also estimated the self-purification capability of TN and TP in Dianshan Lake. The results showed that interannual variability of the average concentration of TN in Dianshan ...
The Baltic Sea, a large estuarine sea in northern Europe, has for many decades displayed obvious signs of anthropogenic eutrophication. This study relates long-term trends in total phosphorus (TP) loadings and TP concentrations in surface waters regarding five major sub-basins of the Baltic Sea; the Bothnian Bay, the Bothnian Sea, the Baltic Proper, the Gulf of Finland and the Gulf of Riga. The...
OBJECTIVE: To assess the utility of the ThinPrep Processor (TP) for nongynecologic cytology. STUDY DESIGN: We reviewed the number of unsatisfactory specimens from the esophagus, common bile duct, hepatic duct, pancreas, gastric, bronchial wang, vertebra, submandibular area and neck over a one-year period, before and after TP implementation. For a one-year period after TP implementation, the cyt...
Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a rare autosomal recessive mitochondrial disease associated with mutations in the nuclear TYMP gene. As a result, the thymidine phosphorylase (TP) enzyme activity is markedly reduced leading to toxic accumulation of thymidine and therefore altered mitochondrial DNA. MNGIE is characterized by severe gastrointestinal dysmotility, ne...

Bacteriophage TP-13, a converting phage for sporulation and crystal formation in Bacillus thuringiensis, was isolated from soil. The phage converted anoligosporogenic (sporulation frequency, 10(-8), acrystalliferous mutant to spore positive, crystal positive at a high frequency. Each plaque formed by TP-13 in a lawn of sensitive cells contained spores and crystals. These spores were heat stable...
BACKGROUND Protein tyrosine phosphorylation (TP) of human sperm is related to sperm capacitation and zona pellucida (ZP) binding. The aim of this study was to determine whether the TP of capacitated sperm is a useful marker for the ability of sperm to bind to the ZP and undergo the ZP-induced acrosome reaction (AR). METHODS Semen samples were obtained from 115 subfertile men with sperm count ...
BACKGROUND 5-Fluorouracil (5-FU) is the cornerstone of chemotherapeutic treatment for patients with colorectal cancer. The enzyme thymidine phosphorylase (TP) catalyzes the conversion of 5-FU to its active metabolite, 5-fluoro-2'-deoxyuridine. TP is expressed in tumour epithelial cells and stromal cells, particularly in tumour-associated macrophages. These macrophages may affect sensitivity to ...
