We studied acquisition of new concepts in semantic dementia patients, who have cortical damage centred on the ventrolateral aspects of the ATLs. Patients learned to assign abstract visual stimuli to two categories. The categories conformed to a family resemblance structure in which no individual stimulus features were fully diagnostic; thus the task required participants to form representations that integrate multiple features into a single concept. Patients were unable to do this, instead responding only on the basis of individual features. The study reveals that integrating disparate sources of information

into novel coherent concepts is a critical computational function of the ATLs. This explains the central role of this region in conceptual representation and the catastrophic breakdown of concepts in semantic dementia. (C) 2013 The Authors. Published by Elsevier Ltd. All rights reserved.”
“To assess the prevalence of renal disorders BVD-523 price and renal dysfunction in patients with Stage I-III primary arterial hypertension, AH (n=1846, 837 men and 1009 women aged from 16 to 72 years), a clinical, biochemical, and instrumental examination was performed It Included urine assay, Nechiporenko and Zimnitsky urine tests, assessment of glomerular filtration rate (GFR) by endogenous creatinine clearance, measurement of microalbuminuria,

blood AG 1879 levels of urea, creatinine and uric acid, renal and pelvic ultrasound, colour Doppler ultrasound of renal vessels, dynamic renal scintigraphy, static renal scintigraphy, excretory urography, and, if necessary, X-ray contrast angiography of renal vessels\n\nEven in the patients from the youngest age group (16-39 years), there were signs of structural renal disorders and renal dysfunction (over 50% of the participants), congenital and acquired renal vessel or abdominal aorta pathology (20%),

and disturbed nitrogen excretion rate (33%) In the patients aged 40-72 years, the prevalence of these disturbances was even higher\n\nThe nature of renal, urn-renal, and renovascular pathology was different across age groups this website of AH patients In younger participants, congenital pathology and nephroptosis were much more prevalent than in patients aged over 40 years On the other hand, older patients were characterised by high prevalence of pyelonephritis, renal cysts, hydronephrosis, abdominal and thoracic aorta deformation, atherosclerotic stenosis of additional renal arteries, nephroptosis (without co-existing obesity), nephrosclerosis and reduction in functioning renal parenchyma”
“Studies have been conducted on selecting yeast strains for use in fermentation for ethanol production to improve the performance of industrial plants and decrease production costs. In this paper, we study alcoholic fermentation in a fed-batch process using a Saccharomyces cerevisiae yeast strain with flocculant characteristics.
