Many previous observers have reported some qualitative similarities between the normal mental state of dreaming and the abnormal mental state of psychosis. Recent psychological, tomographic, electrophysiological, and neurochemical data appear to confirm the functional similarities between these 2 states. In this study, the hypothesis of the dreaming brain as a neurobiological model for psychosi...

In this work, graphene nanoribbons and nanoplatelets were investigated as contrast agents for photoacoustic and thermoacoustic tomography (PAT and TAT). We show that oxidized single-and multi-walled graphene oxide nanoribbons (O-SWGNRs, O-MWGNRs) exhibit approximately 5-10 fold signal enhancement for PAT in comparison to blood at the wavelength of 755 nm, and approximately 10-28% signal enhance...

OBJECTIVE Previous research examining self-concept differentiation (SCD) has been characterized by (a) a focus on behavioral traits and (b) the conflation of mean-level and inter-contextual differentiation. In two studies, we considered non-conflated measures of SCD at the three levels of personality description in relation to adjustment. METHOD In Study 1, participants completed measures of ...

INTRODUCTION Many additional tasks in the Stat laboratory (SL) increase the workload. It is necessary to control them because they can affect the service provided by the laboratory. Our aim is to calculate these tasks, study their evolution over a 10 year period, and compare turnaround times (TAT) in summer period to the rest of the year. MATERIALS AND METHODS Additional tasks were classified...

We previously reported enhanced expression of the p67(phox) and gp91(phox) components of NAD(P)H oxidase in angiotensin (Ang) II-induced hypertension, suggesting de novo assembly in response to Ang II. To examine the direct involvement of NAD(P)H oxidases in Ang II-induced O(2)(-) production, we designed a chimeric peptide that inhibits p47(phox) association with gp91(phox) in NAD(P)H oxidase (...

BACKGROUND An integrated tiered service delivery model (ITSDM) has been proposed to provide 'full-coverage' of CD4 services throughout South Africa. Five tiers are described, defined by testing volumes and number of referring health-facilities. These include: (1) Tier-1/decentralized point-of-care service (POC) in a single site; Tier-2/POC-hub servicing processing < 30-40 samples from 8-10 heal...

The North American Free Trade Agreement (NAFTA) will lower barriers to trade and investment across the continent. This paper presents predictions of the effects of NAFTA on Mexico’s imports of intermediate wood products, scrap and waste paper, pulp, and newsprint from the United States and Canada. Predictions were made with a partial equilibrium model. Model development involved estimating (i) ...

Congenital hypothyroidism is the most common endocrine disease in infants. Through early identification and treatment of affected patients, delays in cognitive and motor development can be effectively prevented. In this topical update, Dr Liz Yuen reviews the aetiology and shares recent advances in understanding the molecular basis of congenital hypothyroidism. Genetic diagnosis and counselling...
