OBJECTIVE Prenatal cocaine exposure (PCE) can cause persistent neuropsychological and motor abnormalities in affected children, but the physiological consequences of PCE remain unclear. Conclusions drawn from clinical studies can sometimes be confounded by polysubstance abuse and nutritional deprivation. However, existing observations suggest that cocaine exposure in utero, as in adults, increa...

Two experiments were carried out to examine the effect of interruption position and interruption duration on postcompletion error (PCE) occurrences in a game-like procedural task. Experiment 1 showed a significant main effect of interruption position on PCE rate; significantly more PCEs were obtained when the interruption occurred just before the PC step than interruptions at any other position...

This paper describes the basic concepts of point-to-multipoint (p2mp) path computation on the basis of the Path Computation Element Metric Protocol (PCEMP). PCEMP, being soft-memory based, has the capability of dynamic configuration of its finite state machines (FSMs) in the participating PCEMP peers, and thus can support a wide variety of traffic engineering techniques that are needed to guara...

A two-dimensional infiltration experiment was conducted to investigate and quantify the effect of spatial wettability variations on DNAPL migration and entrapment in saturated sands. Experimental observations of tetrachloroethylene (PCE) infiltration showed that organic-wet sand lenses acted as very effective capillary barriers, retaining PCE and inhibiting its downward migration. A multiphase ...

Microbiological degradation of perchloroethylene (PCE) under anaerobic conditions follows a series of chain reactions, in which, sequentially, trichloroethylene (TCE), cis-dichloroethylene (c-DCE), vinylchloride (VC) and ethene are generated. First-order degradation rate constants, partitioning coecients and mass exchange rates for PCE, TCE, c-DCE and VC were compiled from the literature. The ...

High-mobility group box-1 (HMGB1) is a well-known pro-inflammatory cytokine. We aimed to investigate the effect of the ethanol extract of the root of P. cuspidatum (PCE) on retinal inflammation in diabetic retinopathy. PCE (100 or 350 mg/kg/day) was administered to diabetic rats for 16 weeks, and hyperglycemia and body weight loss developed in the diabetic rats. The retinal expression levels of...

The gram-negative, strictly anaerobic epsilonproteobacterium Sulfurospirillum multivorans is able to gain energy from dehalorespiration with tetrachloroethene (perchloroethylene [PCE]) as a terminal electron acceptor. The organism can also utilize fumarate as an electron acceptor. Prolonged subcultivation of S. multivorans in the absence of PCE with pyruvate as an electron donor and fumarate as...

High re-attendance rates are common after asthma emergency department (ED) care. Inadequate patient education has been cited as a potential cause of re-attendance and the optimal format of education is uncertain. The present study aimed to compare the effectiveness of patient-centred education (PCE) and standard asthma patient education on ED re-attendance. A randomised controlled trial was con...

Hierarchical PCE is a standard architecture for multi-domain path computation. However, the mechanism to feed the Traffic Engineering Database of the Parent PCE is still under debate. This work validates the use of BGP-LS to build the Parent PCE TEDB and compares two H-PCE algorithms that use different amount of information. Introduction The International Engineering Task Force (IETF) has defin...

BACKGROUND In many studies, chemicals and natural materials were tested to reduce the harmful effects of radiation. It is known that Famotidine and vitamin C reduce DNA damage. OBJECTIVE The aim of this study was to evaluate the radioprotective effect of vitamin C, Cimetidine and Famotidine on gamma-radiation-induced damage on mouse bone marrow. METHODS Six-to-seven week male NMRI mice (28 ...
