Since final mitral valve (MV) closure and aortic ejection velocity are mediated by the same forces in early left ventricular (LV) contraction, the rate of final MV closure (BC slope) should reflect LV performance. We first verified whether peak final closing velocity (ds/dt) of the anterior MV leaflet (AMVL) is related to peak aortic ejection velocity (V) and LV dp/dt in 18 open-chest dogs. We ...
DTS-II is a highly diphtheria toxin (DT)-sensitive cell line previously isolated by transfection of wild-type DT-resistant mouse L-M(TK-) cells with the cDNA encoding a monkey Vero cell DT receptor. DTS-II cells are as toxin-sensitive as Vero cells, have approximately 3-fold more receptors than Vero cells, and have approximately 10-fold lower affinity for DT than Vero cells. We now cotransfecte...
Conformational changes of poly(dA-dT) . poly(dA-dT) induced by increasing ionic strength were studied using CD spectroscopy. It was found that a pronounced noncooperative inversion of the long-wavelength part of the CD spectrum of poly(dA-dT) . poly(dA-dT) occurred at high concentrations of CsF in solution. It was suggested that a great difference between the geometries of the purine and pyrimi...
For every oriented tree T there exists a graph DT (called the dual of T ) such that T 6→ G ⇔ G → DT holds for every G (an arrow denotes the existence of a homomorphism). An explicit construction of DT has been found recently. Although the DT constructed this way may have exponential number of vertices in |V (T )| = n, we will prove that its diameter is linear in n (and therefore DT is ”small” i...
A high drive-for-thinness (DT) score obtained from the Eating Disorder Inventory-2 is associated with surrogate markers of energy deficiency in exercising women. The purposes of this study were to confirm the association between DT and energy deficiency in a larger population of exercising women that was previously published and to compare the distribution of menstrual status in exercising wome...

INTRODUCTION Treatment with ritonavir-boosted protease inhibitors and nucleoside analogues frequently leads to rises in lipids, which might increase the cardiovascular risk. The aim of this study was to describe changes in lipid levels among HIV positive patients participating in the GARDEL study. MATERIALS AND METHODS The GARDEL study compared the efficacy and safety of a dual therapy (DT) c...
347 Abstract: In this study the effect of diphtheria toxin (DT) on nitric oxide (NO) production from RAW 264.7 murine macrophages was investigated. Griess reagent was used to determine NO production by measuring nitrite levels in the culture supernatants. Corynebacterium diphtheriae G12/6 strain-produced DT (Limes flocculation activity and immunodiffusion assays were positive) demonstrated a do...
BACKGROUND Because of reduced vaccination programs, the number of diphtheria infections has increased in the last decade. Diphtheria toxin (DT) is expressed by Corynebacterium diphtheriae and is responsible for the lethality of diphtheria. DT inhibits cellular protein synthesis by ADP-ribosylation of the eukaryotic elongation factor 2 (eEF2). No in vitro system for the quantification of DT enzy...
This study aimed to explore the effect of DT-13 (25(R,S)-ruscogenin- 1-O- [β-d-glucopyranosyl- (1→2)][β-d-xylopyranosyl-(1→3)]-β -d- fucopyranoside) on tumor necrosis factor (TNF)-α-induced vascular inflammation and the potential molecular mechanisms. In vitro, DT-13 suppressed TNF-α-induced adhesion and migration of human umbilical vein endothelial cells (HUVECs) by inhibiting the expression o...
