Abstract: the objective of this study was to determine the chemical profile of sugarcane spirits produced by different double distillation methodologies in rectifying still. fermented sugarcane juice was distilled in rectifying still according to three double distillation methodologies: the methodology used for cognac production; the methodology used for whisky production; and the 10-80-10 percentage composition methodology, referring to the volumes of head, heart and tail of the distillate fractions from the second distillation. for comparison purposes, a simple distilled spirit was also produced. the distillates were analyzed for concentrations of ethanol, copper, volatile acidity, furfural and hydroxymethylfurfural, aldehydes, esters, methanol and higher alcohols. the spirits were also evaluated on the sensory attributes of aroma, taste and preference. compared to simple distillation, double distillation improved the chemical quality of the spirits, since it has reduced the concentrations of acids, aldehydes, esters, methanol, higher alcohols and, consequently, their coefficient of congeners. regardless of the methodology employed, the double distillation improved the sensory quality of the spirits since they obtained higher sensory acceptance in relation to spirits produced by simple distillation. among double distilled spirits, the one produced according to whisky methodology obtained the best scores from appraisers on the aroma and flavor parameters and it was also the most preferred.

Abstract: the qualitative variation of secondary components plays a key role in the aroma and taste of the sugarcane spirit. the objective of this work was to study the volatilization kinetics of secondary components of sugarcane spirits during double distillation process in a rectifying still to verify the cutoff point in ethanol between "head" and "tail" fractions. fermented sugarcane juice was distilled in rectifying still according to the methodology used for whisky production. both distillates from first and second distillations were collected in fractions of 500 ml and analyzed for the concentrations of ethanol, copper, volatile acidity, furfural and hydroxymethylfurfural, aldehydes, esters, methanol and higher alcohols. in the first distillation, aldehydes and esters were distilled at the beginning of the distillation, while acetic acid was distilled at the end of the distillation. methanol was found in the fractions up to almost half of the first distillation. higher alcohols were distilled during the whole first distillation, but with greater intensity up to the alcoholic degree of 40% v v-1 of the distillate. during the second distillation, aldehydes, esters and methanol were distilled in the first distillate fractions, being collected mainly at alcohol concentrations above 80% v v-1. acetic acid was distilled in the final distillate fractions, with concentrations in alcohol content below 20% v v-1. higher alcohols followed a distillation kinetics pattern similar to ethanol, being collected mainly at alcoholic concentrations above 60% v v-1 of the distillate. the presence of copper, furfural and hydroxymethylfurfural was not detected in any fraction of the distillates of the first and second distillation.

Abstract: feline immunodeficiency virus (fiv) infection of domestic cats is one of the most promising animal models for the infection by the human immunodeficiency virus (hiv) which causes acquired immunodeficiency syndrome (aids). infected cats may develop a disease similar to that observed in aids patients, with increased susceptibility to opportunistic infections. in this study we used the polymerase chain reaction (pcr) to detect proviral dna of feline immunodeficiency virus on the blood and tissue samples from cats with a clinical diagnosis of immunodeficiency. the pcr primers were used to amplify the gag gene, which is conserved among different isolates. from 40 samples analyzed, 15 were positive and 4 of them were submitted to hybridization to confirm the specificity of the amplified fragments. these results confirm the presence of fiv in domestic cats in rio grande do sul, brazil.

Abstract: A infec o de gatos domésticos pelo Vírus da Imunodeficiência Felina (FIV) é um dos modelos mais promissores para o estudo da infec o pelo vírus da imunodeficiência humana (HIV) que causa a Síndrome de Imunodeficiência Adquirida (AIDS). O FIV causa, em gatos, uma enfermidade similar àquela observada em pacientes com AIDS, sobretudo no que diz respeito ao aumento da susceptibilidade a infec es oportunistas. No presente estudo, utilizou-se a Rea o em Cadeia da Polimerase (PCR), com o objetivo de detectar o provírus do FIV em gatos com sinais clínicos de imunodeficiência. O fragmento de DNA escolhido como alvo para amplifica o situa-se no gene gag do lentivírus felino, o qual é conservado entre as diferentes amostras do vírus. O DNA utilizado foi extraído a partir de amostras de sangue e de tecidos de animais com suspeita clínica de imunodeficiência. Das 40 amostras analisadas, 15 foram positivas, das quais 4 foram submetidas à hibridiza o, confirmando a especificidade dos fragmentos amplificados. Esses resultados demonstram a presen a do FIV na popula o de gatos domésticos do Rio Grande do Sul, Brasil.

Abstract:

Fast and unequivocal methods of questioned document analysis are essential in forensic science. Here, a desorption/ionization technique, EASI-MS, was assessed for its ability to investigate questioned driver’s licenses (DL). Two suspects DL, displaying the same personal data in the proper fields (name and ID numbers), but with different individual photos, showing similar impressions on microscopic analysis, and authentic standards documents specimens were used as test cases. Profiles from authentic DL surface were dominated by a set of few minor ions, mainly from the plasticizers bis(2-ethylhexyl)phthalate and dibutylphthalate. The seized suspect counterfeit DL on points from personal data and photo were, however, dominated by abundant diagnostic ions of m/z 463, 507, 551, 595, 639, 683, which confirmed counterfeiting. Surfynol® and Nonoxynol-9®, which are common constituents of inkjet printing, were detected in the counterfeiting areas by high-accuracy EASI(+)-FT-ICR MS. The EASI-MS technique is shown therefore to offer an attractive tool for forensic investigation of questioned documents.
