Abstract: Background There is a high prevalence of vitamin D insufficiency in women of reproductive age. Methods This work studied the first two generations of offspring (F1 and F2) of Swiss mice from mothers fed one of two diets: SC (standard chow) or VitD- (vitamin D-deficient). Functional and developmental kidney measurements were taken. Results The first two generations of the VitD- group had higher blood pressure at 6 months of age than the offspring of the SC group as well as an increase in renin and AT1r expression. However, at all ages, both F1 and F2 VitD- mice had shorter glomerular diameters, and diet played a significant role in the total variation. Both the F1 and F2 generations of the VitD- group had more immature glomeruli than offspring from the SC group. Immature glomeruli begin to disappear at 10 days, but at this age, F1-VitD- mice had more immature and mature glomeruli than F1-SC mice. At 6 months of age, F1-VitD- mice exhibited more glomeruli, while F2-VitD- mice exhibited the same number of glomeruli as F2-SC mice, but fewer glomeruli compared to the F1-VitD group. Both diet and generation account for the total variation in the number of glomeruli. Decreases in urine output and podocin expression and increases in urea and creatinine in the urine were observed in F1 offspring. Conclusion These findings demonstrate that maternal vitamin D deficiency accompanies changes in the renal expression of important factors that may retard the maturation of glomeruli by extending the period of nephrogenesis.

Abstract: the main objetive of this work was to evaluate the anaerobic digestion of cheese whey (68.000mg cod/l), without whey ph adjustment, incomplete mixture semi-continuous laboratory reactors with temperature maintained at 35° ± 1°c. cattle manure with 8% total solids was used for seeding the reactors. the experiment was carried out for a period of 100 days. the first 20 days were characterized for the aclimatization of seed manure and four 20 days periods as hydraulic retention times (?). a loading of 3,0g cod/l digester/day was fed to each digestor. in the 1rst ? the loading was divided in three portions and fed to the reactors at intervals of 8 hours. in the 2nd the loading was divided in two portions and fed to the reactors at intervals of 12h; in the 3th ? a 6h interval of feeding was used, and the loading divided in four portions; the 4th ? was characterized by feeding the total loading to the reactor at once. the experiment was controled by the following analysis: volatile acidity, alkalinity, ph, volume of biogas produced and chemical oxigen demand (cod). the results obtained show an effect of the feeding system on the process of anaerobic digestion of whey. the increase in volatile organic acid production at the retention times studied caused a change in the equilibrium of the microbial population and consequently lowered the efficiency of the process. under these condition biogas production expressed as 1.gas/g of cod used was 0.35 l/g.

Abstract: O mel é um alimento apreciado por seu sabor característico e pelo seu considerável valor nutritivo. Devido a oferta do produto ser menor que a procura, seu pre o é relativamente alto, incentivando sua adultera o. Geralmente, a adultera o do mel é feita através da adi o de a úcares comerciais, derivados de cana-de-a úcar e milho. Como essas plantas têm uma composi o isotópica do carbono distinta das plantas utilizadas pelas abelhas como fonte de néctar (flores silvestres, citros e eucaliptos), é possível utilizar a composi o isotópica do carbono de amostras de mel para se avaliar a adultera o desse produto por a úcares comerciais oriundos da cana e do milho. Foram analisadas amostras de plantas pertencentes ao ciclo fotos-sintético C3, subprodutos de plantas C4 (a úcares comerciais) e 61 amostras de mel obtidas no mercado. As plantas C3 analisadas apresentaram valores de d13C de -28,9±1,1? (n=8), enquanto os a úcares apresentaram valores de -11,1±0,7? (n=3). Das 61 amostras de mel analisadas, cerca de 8% (5 amostras) tiveram sinais claros de adultera o. A amostra de número 34 teve um valor igual a -12,9?, indicando que a úcar puro de cana-de-a úcar ou milho estaria sendo comercializado como mel. As amostras 13, 14, 33 e 54 apresentaram valores iguais a -21,0; -19,9; -21,9 e -17,6?, respectivamente. Esses valores indicam também adi o de a úcares de cana-de-a úcar ou milho, no entanto em menor propor o. A metodologia testada neste trabalho foi aprovada como um método simples, confiável e complementar aos métodos químicos e físicos convencionais visando detectar adultera o de mel.

Abstract: a variety of studies involving schizophrenic patients have shown the occurrence of severe disabilities related to perception and cognition. most diagnostics rely on alterations that reveal faulty reasoning. our studies evaluate altered visual form and size perception in schizophrenic and major depression patients using 24 paintings by salvador dalí. we conducted two studies comparing experimental and control groups and found in both cases that schizophrenic patients first saw forms 1.5-3.0 times larger than controls. in another study with major depression patients, we show the absence of alterations in size perception during aggravated depressive symptoms. these effects on size perception can contribute as markers in the precocious diagnostic of the onset of positive symptoms in schizophrenia. we suggest that these paintings by dalí can be employed as a tool to assess the state of visual form and size perception in schizophrenic patients, and therefore prevent cognitive deterioration by introducing early treatment.

Abstract: c57bl/6 mice develop signs and symptoms comparable, in part, to the human metabolic syndrome. the objective of the present study was to evaluate the effects of exercise training on carbohydrate metabolism, lipid profile, visceral adiposity, pancreatic islet alterations, and nonalcoholic fatty liver disease in c57bl/6 mice. animals were fed one of two diets during an 8-week period: standard (sc, n = 12) or very high-fat (hf, n = 24) chow. an exercise training protocol (treadmill) was then established and mice were divided into sc and hf sedentary (sc-sed, hf-sed), exercised groups (sc-ex, hf-ex), or switched from hf to sc (hf/sc-sed and hf/sc-ex). hf/hf-sed mice had the greatest body mass (65% more than sc/sc-sed; p < 0.0001), and exercise reduced it by 23% (p < 0.0001). hepatic enzymes alp (+80%), alt (+100%) and ast (+70%) were higher in hf/hf mice than in matched sc/sc. plasma insulin was higher in both the hf/hf-sed and hf/sc-sed groups than in the matched exercised groups (+85%; p < 0.001). pancreatic islets, adipocytes and liver structure were greatly affected by hf, ultimately resulting in islet β-cell hypertrophy and severe liver steatosis. the hf group had larger islets than the sc/sc group (+220%; p < 0.0001), and exercise significantly reduced liver steatosis and islet size in hf. exercise attenuated all the changes due to hf, and the effects were more pronounced in exercised mice switched from an hf to an sc diet. exercise improved the lipid profile by reducing body weight gain, visceral adiposity, insulin resistance, islet alterations, and fatty liver, contributing to obesity and steatohepatitis control.

Abstract: the present study investigates the calliphorid fauna in the biological reserve of tinguá using faunistic indices. monthly samplings were carried out using traps containing sardines that were exposed for 48 hours at the sites: a, at the border of the forest; b, 1,000 m towards the interior of the forest; and c, 500 m towards the interior of the forest. the objective was to study the calliphoridae fauna in forest environments using faunal indices. during the course of the experiment, 26 calliphorid species were collected. the species singletons, doubletons, uniques, duplicates, intermediate and common were defined. richness and richness estimation (estimators chao 1 and 2, jackknife 1 and 2, ace, ice and bootstrap), diversity (shannon-wiener index), evenness (pielou's index), and similarity of the sites (using the sorensen coefficient and the southwood percent similarity) were calculated. sites a and b had the same number of species of calliphoridae (23), representing a greater richness than site c (16). the sites differed only in their rare, intermediate and common species composition. the greatest number of intermediate species was found at a. at b, the numbers of rare, intermediate and common species were similar. at c, there were fewer rare species than intermediate and common ones. jackknife 2 at site b produced a higher value, however, indicating that it was possible to collect five other species in the reserve and three more species at a and c. diversity was greatest at b, but evenness was similar at the sites. b and c showed a greater level of similarity in species composition (dendogram); l. nigripes and mesembrinella bellardiana, which are the most important species at these two sites, appeared grouped together. chrysomya albiceps, chrysomya megacephala and hemilucilia semidiaphana, the main species at site a, also appear together.

Abstract: Neste trabalho buscou-se analisar o efeito de diferentes manejos de água residuária de suinocultura e de água de abastecimento na obstru o de emissores e na uniformidade de aplica o de sistemas de irriga o por gotejamento. O experimento foi realizado na Universidade Federal de Vi osa (UFV) e montado em esquema de parcelas subsubdivididas tendo, nas parcelas, os manejos (1E3A - uma hora de aplica o de efluente mais três horas de aplica o de água limpa, 2E2A - duas horas de aplica o de efluente mais duas horas de aplica o de água limpa, 3E1A - três horas de aplica o de efluente mais uma hora de aplica o de água limpa e 4E - quatro horas de aplica o de efluente), nas subparcelas os tipos de gotejador (G1, G2 e G3) e, nas subsubparcelas, os tempos das avalia es (0, 20, 40, 60, 80, 100, 120, 140 e 160 h) em delineamento inteiramente casualizado com três repeti es. Os resultados obtidos indicaram que na água residuária de suinocultura as características sólidos suspensos, ferro total e popula o bacteriana, representaram risco severo de entupimento de gotejadores e que houve redu o elevada da uniformidade de aplica o de efluente quando o tempo de aplica o de água residuária foi igual ou superior ao da água de abastecimento. This study aimed to evaluate the effect of different managments of swine wastewater and clean water on clogging of emitters and application uniformity of drip irrigation systems. The experiment was conducted in the experimental area of the Federal University of Vi osa (UFV) and mounted in a split split-plots, having in the plots the managments (1E3A - one hour of application of effluent and three hours of application of clean water, 2E2A - two hours of application of effluent and two hours of application of clean water, 3E1A - three hours of application of effluent and one hour of application of clean water and 4E - four hours of application of effluent), in the subplots the types of drippers (G1, G2 and G3) and in the subsubplots the evaluation times (0, 20, 40, 60, 80, 100, 120, 140 and 160 h) in a completely randomized design with three replications. The results indicated that in the swine wastewater the characteristics suspended solids, total iron and bacterial population represented severe risk of clogging of drippers; and that there was a high reduction of the uniformity of application of effluent when the time of application of wastewater is equal to or greater than the water supply.
