A fundamental question to be clarified concerning the host cell invasion by Trypanosoma cruzi is whether the insect-borne and mammalian-stage parasites use similar mechanisms for invasion. To address that question, we analysed the cell invasion capacity of metacyclic trypomastigotes (MT) and tissue culture trypomastigotes (TCT) under diverse conditions. Incubation of parasites for 1 h with HeLa...

The purpose of this study was to evaluate prospectively the Trunk Control Test (TCT) correlation at admission to rehabilitation with length of stay, functional independence measure (FIM), gait velocity, walking distance and balance measured at discharge in 28 hemiparetic patients. FIM and TCT were registered on admission. Outcome measures at discharge were: FIM, gait velocity, walking distance ...

The addition of the antibiotic ristocetin to plasma accelerated the thrombin clotting time (TCT) in 20 out of 22 subjects. Prior incubation of ristocetin with thrombin or plasma did not alter its effect on the TCT. Ristocetin accelerated clotting greatly at low but not at high levels of thrombin. A simple linear correlation between heparin concentrations and the TCT was demonstrated when ristoc...

Purpose. To analyze the outcomes and difference after UVA/riboflavin corneal collagen crosslinking (CXL) in four different corneal thickness groups of patients with progressive keratoconus. Methods. Retrospective study. Eyes with progressive keratoconus after CXL were divided into 4 subgroups as follows: group 1, thinnest corneal thickness (TCT) ≤ 400 µm; group 2, 400 µm < TCT ≤ 450 µm; group 3...

Specific destruction of ciliated epithelial cells lining the large airways is the primary respiratory tract cytopathology associated with human Bordetella pertussis infections. We have purified a single low-molecular-weight glycopeptide, tracheal cytotoxin (TCT), that appears to cause this pathology. By using a combination of solid-phase extraction and reversed-phase high-pressure liquid chroma...

Transaction Cost Theory (TCT) has been widely used in information technology outsourcing (ITO) research to explain and predict outsourcing decisions and outsourcing-related outcomes. This research, however, has led to mixed and unexpected results in terms of the effects of transaction attributes on outsourcing decisions and outcomes. This study assesses the empirical literature employing TCT-ba...

The TCT core promoter element is present in most ribosomal protein (RP) genes in Drosophila and humans. Here we show that TBP (TATA box-binding protein)-related factor TRF2, but not TBP, is required for transcription of the TCT-dependent RP genes. In cells, TCT-dependent transcription, but not TATA-dependent transcription, increases or decreases upon overexpression or depletion of TRF2. In vitr...

Tracheal cytotoxin (TCT) was originally described as the minimal effector that was able to reproduce the cytotoxic response of Bordetella pertussis on ciliated epithelial cells. This molecule triggers pleiotropic effects such as immune stimulation or slow-wave sleep modulation. Further characterization identified TCT as a specific diaminopimelic acid (DAP)-containing muropeptide, GlcNAc-(anhydr...

Forensische Analysen mit freien OpenSource Programmen sind seit Dan Farmers und Wietse Venemas ersten und einzigen Forensik-Kurs und der darauf folgenden Veröffentlichung des Coroner’s Toolkits [1] im Jahr 1999 kein unbekannter Faktor mehr. Allerdings mussten sich die OpenSource-Lösung von jeher den Vorwurf gefallen lassen, im Gegensatz zu ihrer kommerziellen Konkurrenz umständlich bedienbar un...
