Analysis of chemical warfare agents (CWAs), their precursors and degradation products (DPs) is an important verification component in support of the Chemical Weapons Convention and urgently demanding rapid and reliable analytical methods. Considering a growing number of papers presented in the last years in the field of capillary electrophoresis (CE) of DPs, this review article gives an overvie...

OBJECTIVE Presentation and validation of the Depressive Psychopathology Scale (DPS), a new, Spanish-language psychometric inventory, in a sample of Peruvian psychiatric patients. METHODS From 1999 to 2001, the DPS, Zung Self-rating Depression Scale (ZSDS), and Major Depressive Disorder (MDD) module of the Structured Clinical Interview for DSM-IV Disorders (SCID) were administered to 226 nonps...

[1] The analytical formulation of the Dessler-Parker-Sckopke (DPS) equation relating the energy content of the ring current to the magnetic field depression at the Earth’s center is examined. To conduct this study, a method is presented for numerically integrating inner magnetospheric pressure distributions according to the Biot-Savart law to obtain magnetic field perturbations at an arbitrary ...

The peroxide response-inducible genes ahpCF, dps, and katB in the obligate anaerobe Bacteroides fragilis are controlled by the redox-sensitive transcriptional activator OxyR. This is the first functional oxidative stress regulator identified and characterized in anaerobic bacteria. oxyR and dps were found to be divergently transcribed, with an overlap in their respective promoter regulatory reg...

Nutrients and other bioactive constituents of foods may interact with each other and the surrounding food matrix in complex ways. Therefore, associations between single nutrients and chronic disease may be difficult to identify and interpret, but when dietary patterns (DPs) are examined the combination of many food factors will be considered. An explorative literature search of published review...

Intradermal adipose tissue plays an essential role for hair follicles (HFs) regeneration by regulating hair cycles. However, the effect of reconstruction of HFs and the involvement of adipose-related cells are poorly understood. We investigated assembly strategies for the interactions of dermal papilla (DP) cells with adipose-derived stem cells (ASCs) in promoting hair formation. DP cells lose ...

The transition from adolescence to adulthood is a unique period during which lifelong dietary habits are shaped. Dietary patterns (DPs) among young adults attending college have not been adequately described, and associations between DPs and indicators of disease risk are not well understood in this age group. Dietary data were collected from undergraduates participating in the Tufts Longitudin...

We develop a stochastic mean-value method for the derivation of delay asymptotics in Processor-Sharing (PS) type systems with heavy-tailed service requirements. In order to demonstrate the strength of the approach, we apply the method to obtain the sojourn time asymptotics for a multi-class G/G/1 queue operating under the Discriminatory Processor-Sharing (DPS) discipline. Besides interesting fr...

An Escherichia coli O157:H7 dps::nptI mutant (FRIK 47991) was generated, and its survival was compared to that of the parent in HCl (synthetic gastric fluid, pH 1.8) and hydrogen peroxide (15 mM) challenges. The survival of the mutant in log phase (5-h culture) was significantly impaired (4-log(10)-CFU/ml reduction) compared to that of the parent strain (ca. 1.0-log(10)-CFU/ml reduction) after ...

This study was undertaken to determine the rates of sterol synthesis and uptake in the major organs of the female rat in vivo. At the mid-dark phase of the light cycle, control animals, animals in which hepatic sterol synthesis had been selectively inhibited by chylomicron infusion and animals in which the small intestine and liver had been surgically removed, were administered [(3)H]water, and...
