The incomplete consumption of sugar resulting from stuck wine fermentation is associated with important economic losses. One of the solutions to this serious problem consists of reinoculating the brew with a yeast starter culture that is both alcohol tolerant and a vigorous fructose fermenter. The present work aimed to select yeast strains capable of(More)
Untreated streptozocin-induced diabetic (STZ-D) rats have previously been shown to have significantly increased hypothalamic concentrations of neuropeptide Y (NPY), a regulatory peptide that powerfully stimulates eating and drinking and inhibits secretion of several pituitary hormones when injected centrally. Tissue NPY concentrations have been measured by(More)
Central and lateral hypothalamic concentrations of 10 regulatory peptides were measured by radioimmunoassay in streptozocin-induced diabetic (STZ-D) and matched control rats between 1 day and 14 wk after diabetes induction. After 2 wk, both central and lateral hypothalamic neuropeptide Y (NPY) concentrations in STZ-D rats were consistently higher than those(More)
Cat eye syndrome is a rare congenital disease characterized by the existence of a supernumerary chromosome derived from chromosome 22, with a variable phenotype comprising anal atresia, coloboma of the iris and preauricular tags or pits. We report a girl with cat eye syndrome, presenting short stature, with growth hormone deficiency due to posterior(More)
OBJECTIVE optimism is an important variable that has consistently been shown to affect adjustment to quality of life in chronic diseases. This study aims to clarify if dispositional optimism exerts a moderating or a mediating influence on the personality traits-quality of life association, in Portuguese chronic patients. METHODS multiple regression models(More)
We report a large genomic deletion of the cystic fibrosis transmembrane conductance regulator (CFTR) gene, viz., a deletion that is frequently observed in Central and Eastern Europe. The mutation, termed CFTRdele2,3(21 kb), deletes 21,080 bp spanning introns 1–3 of the CFTR gene. Transcript analyses have revealed that this deletion results in the loss of(More)
1. Hypothalamic concentrations of nine peptides with experimental effects on energy balance were compared in obese (fa/fa) and lean (Fa/?) male Zucker rats. To determine whether any peptide differences between obese and lean rats might be due to the overweight condition per se, separate groups of obese rats were food-restricted to reduce their body weight(More)
Central and lateral hypothalamic concentrations of 9 regulatory peptides implicated in the control of feeding behaviour were measured in corpulent (cp/cp) JCR:LA-cp rats which develop spontaneous obesity, hyperinsulinaemia and hyperlipidaemia, and in lean (+/?) controls. In female cp/cp rats, central hypothalamic levels of neuropeptide Y (NPY), neurotensin,(More)
OBJECTIVE To determine the spectrum of MEN1 mutations in Portuguese kindreds, and identify mutation-carriers. PATIENTS, DESIGN AND RESULTS Six unrelated MEN1 families were studied for MEN1 gene mutations by single-strand conformational polymorphism (SSCP) and DNA sequence analysis of the coding region and exon-intron boundaries of the MEN1 gene. These(More)
With the objective of evaluating Rhipicephalus (Boophilus) microplus resistance to cipermetrina and amitraz, were collected engorged tick females from cattle on 20 farms on the Santa Catarina Plateau, in southern Brazil, between January of 2004 and May of 2006. Were also received 20 groups of engorged R. (B.) microplus females, collected by cattle farmers(More)
