Thiocyanate Ion, Chloramine-T Kinetics of oxidation of potassium thiocyanate by the oxidant chloramine-T (CAT) in presence of NaOH has been studied at 30 °C. At low substrate concentrations, the approximate rate law is, — d[CAT]/dt = k[CAT][KNCS]/[NaOH]2. At higher substrate concentrations, the rate law simplifies to, —d[CAT]/dt = k[CAT]/[NaOH]. Ionic strength and addition of p-toluene sulphona...
Ca2+ transport in red blood cell ghosts was monitored with fura2 or quin2 incorporated as the free acid during resealing. This is the first report of active transport monitored by the fluorescent intensity of the chelator dyes fura2 (5-50 microM) or quin2 (250 microM) in hemoglobin-depleted ghosts. Since there are no intracellular compartments in ghosts and the intracellular concentrations of a...
Individuals with low distress tolerance (DT) experience negative emotion as particularly threatening and are highly motivated to reduce or avoid such affective experiences. Consequently, these individuals have difficulty regulating emotions and tend to engage in maladaptive strategies, such as overeating, as a means to reduce or avoid distress. Hatha yoga encourages one to implement present-cen...
Negative inotropic agents may differentially modulate indexes of cytosolic [Ca(2+)]-left ventricular (LV) pressure (LVP) relationships when given before and after ischemia. We measured and calculated [Ca(2+)], LVP, velocity ratios [[(d[Ca(2+)]/dt(max))/(dLVP/dt(max)); VR(max)] and [(d[Ca(2+)]/dt(min))/(dLVP/dt(min)); VR(min)]], and area ratio (AR; area [Ca(2+)]/area LVP per beat) before and aft...
The influence of conformational changes on the molecular electrostatic potential and the steric accessibility of the double stranded polynucleotide poly (dA-dT). poly (dA-dT) are investigated by calculating these properties for three different conformations : B-DNA, D-DNA and alternating-B DNA.
In this paper, we compare two different definitions of distance transform for gray level images: the Gray Weighted Distance Transform (GWDT), and the Weighted Distance Transform On Curved Space (WDTOCS). We show through theoretical and experimental comparisons the differences, the strengths and the weaknesses of these two distances. Continuous case D GW DT = 1 0 |π(t)|dt.

The aims of this study were to compare a novel PCR-based Chlamydia trachomatis detection and genotyping (Ct-DT) assay with the FDA-approved, commercially available C. trachomatis detection Hybrid Capture 2 (HC2) assay and to investigate the C. trachomatis serovar distribution among young women in a rural Costa Rican study population. A total of 5,828 sexually active women participating in a com...
BACKGROUND AND PURPOSE In multiple sclerosis (MS), the severity of tissue damage can vary from edema and inflammation to irreversible demyelination and axonal loss. Compared with conventional T2-weighted MR imaging, magnetization transfer (MT) and diffusion tensor (DT) MR imaging provide quantitative indices with increased specificity to the most destructive aspects of MS. To increase our under...
