Die Qualität eines zu entwickelnden Softwareprodukts wird entscheidend durch die Qualität des zugehörigen Testprozesses beeinflusst. Das TPIModell ist ein Referenzmodell zur Bewertung der Qualität eines Testprozesses, das mittels Kontrollpunkten den Reifegrad von Testaktivitäten bestimmt. Dabei ist allerdings sowohl die Interpretation des zu bewertenden Testprozesses, welcher in der Praxis häuf...

Thymidine phosphorylase (TP) is an enzyme involved in the reversible conversion of thymidine to thymine and is identical to an angiogenic factor, platelet-derived endothelial cell growth factor. TP is expressed at higher levels in a wide variety of solid tumors than in the adjacent nonneoplastic tissues. Patients with TP-positive colon and esophageal tumors have a poorer prognosis than those wi...

This work investigated the effect of granular activated carbon adsorption (GACA) on fluorescence characteristics of dissolved organic matter (DOM) in secondary effluent, by means of excitation–emission matrix (EEM) spectra, the fluorescence regional integration (FRI) method, synchronous spectra, the fluorescence index defined as the ratio of fluorescence emission intensity at wavelength 450 nm ...

Triosephosphate isomerase (TPI), a glycolytic enzyme, functions in catalyzing the interconversion of glyceraldehyde-3-phosphate and dihydroxyacetone phosphate and is generally upregulated in tumours. However, there are data suggesting loss in lymphomas. To determine its effects in chicken embryonal fibroblasts (CEF) a plasmid was constructed to allow transfection. Upon culture in a suitable med...

In sera from patients with acute EBV, infection and the clinical symptoms of infectious mononucleosis antibodies of the Ig class M were found that are directed against two cellular proteins. The molecular mass of these proteins was determined to be 29 (p29) and 26 kD (p26), respectively, in SDS-PAGE. P29 was identified as part of the glycolytic enzyme triosephosphate isomerase (TPI) by comparis...

We developed a novel inhibitor of thymidine phosphorylase (TP), 5-chloro-6-[1-(2-iminopyrrolidinyl) methyl] uracil hydrochloride (TPI), that is about 1000-fold more active than 6-amino-5-chlorouracil, one of the most potent TP inhibitors. TPI inhibited the high chemotactic motility and basement membrane invasion of KB/TP cells, a TP-positive clone transfected with Rous sarcoma virus (RSV)/TP, t...

Trifluridine/tipiracil (FTD/TPI) significantly improves overall survival in patients with metastatic colorectal cancer (mCRC). The most common treatment-related event (grade ≥3) was hematological toxicity. We here report long-term disease-stabilizing FTD/TPI treatment of an mCRC patient (KRAS wild-type, ECOG performance status 1 at baseline and at the end of FTD/TPI therapy) with multifocal syn...

UMN-TH-2106/02 TPI-MINN-02/21 astro-ph/0207583 July 2002 Recent observations by Bania et al. (2002) measure He versus oxygen in Galactic H II regions, finding that He/H is within a factor of 2 of the solar abundance for [O/H] & −0.6. These results are consistent with a flat behavior in this metallicity range, tempting one to deduce from these observations a primordial value for the He abundance...

To investigate the effects of triptolide (TPI) on proliferation, autophagy and death in human breast cancer MCF-7 cells, and to elucidate the associated molecular mechanisms, intracellular alterations were analyzed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and flow cytometry assays. The results of the MTT assay revealed that TPI significantly reduced the MCF‐7 cel...
