Background: Pseudocholinesterase (PChE) polymorphism has been a subject of several pharmacogenetic studies worldwide. The patients with atypical homozygous genotype do not only have reduced serum cholinesterase activities but also their elimination rate for some pharmacologically potent drugs decrease drastically. This study was designed to evaluate the PChE polymorphism in Mazandaran province ...

The autonomic nervous system (ANS) is an extensive neural network whose main role is to regulate the milieu intérieur by controlling homeostasis and visceral functions. Although most functions regulated by the ANS are out of conscious control, emotions and somatosensory inputs profoundly influence the ANS. Observing the marked vasomotor and sudomotor changes after traumatic nerve injury, it bec...

Geologic investigations of the Arabian-Nubian Shield (ANS) are supported by a valuable, expanding dataset of geochronologic ages and isotopic analyses. U-Pb zircon SIMS, TIMS, and evaporation data provide robust temporal control on depositional, volcanic, and intrusive events. Nd, Sr, O and, increasingly, Hf isotopic studies provide insights into magma sources and constraints on crustal recycli...

W e read with great interest the article by Leeds et al. (1), which reported an increased prevalence of diabetic nephropathy (DN) and diabetic retinopathy (DR) in adults with type 1 diabetes and newly diagnosed celiac disease (CD). After patients were on a gluten-free diet (GFD) for 1 year, Leeds et al. (1) observed a significant improvement in the prevalence of advanced DN; by contrast, there ...

Genetic algorithms (CA's) are used to search the synaptic weight space of artificial neural systems (ANS) for weight vectors that optimize some network performance function. GA's d o not suffer from some of the architectural constraints involved with other techniques and it is straightforward to incorporate terms into the performance function concerning the metastructure of the ANS. Hence GA's ...

Many children have significant mathematical learning disabilities (MLD, or dyscalculia) despite adequate schooling. The current study hypothesizes that MLD partly results from a deficiency in the Approximate Number System (ANS) that supports nonverbal numerical representations across species and throughout development. In this study of 71 ninth graders, it is shown that students with MLD have s...

L'Insuffisance rénale chronique terminale (IRCT) est un enjeu majeur de sante publique au Maroc à cause de ses conséquences médicales et socioéconomiques. L'objectif de ce travail est d'évaluer le profil épidémiologique de l'IRCT à l'hôpital militaire de rabat, Maroc. Il s'agit d'une enquête rétrospective pendant quatre ans (1 janvier 2007 au 31 décembre 2010). Tous les cas d'IRCT (diminution p...

La cysticercose a une prévalence élevée dans les pays sub-sahariens et son diagnostic reste difficile. Cette étude a pour but de déterminer la valeur diagnostique de la tomodensitométrie dans la cysticercose cérébrale. Recrutement des patients ayant bénéficié d'une tomodensitométrie cérébrale dans l'une des circonstances suivantes: épilepsie, hypertension intracrânienne, syndrome pyramidal, dét...
