ABSTRACT

Objetivou-se analisar os efeitos da inclusão da glicerina bruta (GB), oriunda da produção de biodiesel proveniente de óleos residuais de fritura, sobre o consumo, e os parâmetros hematológicos e bioquímicos em cabras em lactação. Oito cabras com 42,06±3,5kg de peso corporal foram utilizadas, recebendo dietas contendo 0, 7, 14 e 21% de GB com base na MS total da dieta. O experimento foi conduzido em quadrado latino duplo 4×4, com duração de 80 dias, sendo quatro períodos de 20 dias, dos quais 15 para a adaptação e cinco para a coleta de dados. As amostras de sangue foram coletadas pela punção da veia jugular. Os consumos de MS, proteína bruta e matéria mineral decresceram linearmente, enquanto o de extrato etéreo aumentou quadraticamente. As concentrações do hematócrito, hemoglobina, hemácias e fósforo reduziram linearmente. Tendência quadrática foi observada para as concentrações séricas de cálcio. Não foram verificados efeitos para as concentrações de magnésio, glicose, colesterol total, triglicerídeos, proteínas plasmáticas totais, albumina, globulinas, ureia, creatinina, aspartato aminotransferase e fosfatase alcalina. Conclui-se que a GB pode ser utilizada em até 7% da MS total da dieta, sem promover problemas metabólicos.(AU)


The aim of this study was to analyze the effects of the inclusion of crude glycerin (CG) from biodiesel production from waste frying oils on nutrients intake, hematological and biochemical parameters in lactating goats. Eight goats with 42.06±3.5kg of body weight were used, receiving diets containing 0, 7, 14 and 21% of CG based on total dietary DM. The experiment was carried out in a 4×4 double Latin square, with a duration of 80 days, four periods of 20 days, of which 15 days were for adaptation and five days for data collection. Blood samples were collected by puncture of the jugular vein. Dry matter, crude protein, and mineral matter intakes decreased linearly, while intake of ether extract increased quadratically. The concentrations of hematocrit, hemoglobin, red blood cells, and phosphorus reduced linearly. A quadratic tendency for serum calcium concentrations was observed. No effects were observed for concentrations of magnesium, glucose, total cholesterol, triglycerides, total plasmatic protein, albumin, globulins, urea, creatinine, aspartate aminotransferase, and alkaline phosphatase. It can be concluded that CG can be used in up to 7% of total dietary DM without promoting metabolic problems.(AU)

ABSTRACT

Background: Coronary artery disease (CAD) is a multifactorial disease whose etiogenesis involves a number of environmental, genetic and lifestyle-related factors. Genetic polymorphisms are noteworthy among these factors because they alter gene expression and, thus, the functions of the respective products. Methods: A case-control study was conducted in the Cardiology Institute, with 79 subjects classified as cases with CAD, and 96 subjects as controls without CAD or other disease. In this study, we evaluated the association between the single-nucleotide polymorphisms (SNPs) of S447X and Leu7Pro of the lipoprotein lipase (LPL) and neuropeptide Y (NPY) genes, respectively. Results: No differences were found in the frequencies of LPL SNP between the cases and controls. However, the LPL 447X allele carriers exhibited a near-significant difference in the triglycerides (p=0.086) and higher mean in the HDL-c (p=0.018). NPY polymorphisms proved to be infrequent in this study population, and no significant difference was observed between the groups. Conclusions: Our findings provide further support of the genetic polymorphisms effect on the lipid metabolism control. So, further studies are needed to assess the functional effect of this and other polymorphisms, on LPL and in the NPY activity, and their impact on CAD risk.

ABSTRACT

To describe a case of genital burn which raised the suspicion of maltreatment (sexual abuse and neglect by lack of supervision). CASE DESCRIPTION: An infant was taken to the Emergency Room of a pediatric hospital with an extensive burn in the vulva and perineum. The mother claimed the burn had been caused by a sodium-hydroxide-based product. However, the injury severity led to the suspicion of sexual abuse, which was then ruled out by a multidisciplinary team, based on the consistent report by the mother. Besides, the lesion type matched those caused by the chemical agent involved in the accident and the family context was evaluated and considered adequate. The patient had a favorable outcome and was discharged after four days of hospitalization. Outpatient follow-up during six months after the accident enabled the team to rule out neglect by lack of supervision. COMMENTS: Accidents and violence are frequent causes of physical injuries in children, and the differential diagnosis between them can be a challenge for healthcare workers, especially in rare clinical conditions involving patients who cannot speak for themselves. The involvement of a multidisciplinary trained team helps to have an adequate approach, ensuring child protection and developing a bond with the family; the latter is essential for a continued patient follow-up...


Describir un caso de quemadura de los genitales que llevó a la sospecha de malos tratos (abuso sexual y negligencia de supervisión). DESCRIPCIÓN DEL CASO: Lactante fue llevada a la Emergencia de un hospital pediátrico por lesión extensa en región de la vulva y entre la vagina y el ano. La madre alegaba quemadura por producto a base de soda cáustica, pero la gravedad de la lesión llevó el equipo a sospechar de abuso sexual. La sospecha fue alejada por equipo multidisciplinario con base en el relato consistente de la madre, en el tipo de lesión compatible con el agente químico implicado en el accidente y en la evaluación del contexto de vida familiar. El cuadro clínico evolucionó de manera satisfactoria, siendo dada alta después de cuatro días de internación. El seguimiento ambulatorial en los seis meses posteriores permitió alejar también una posible situación de negligencia de supervisión, con base en la historia previa del niño, en su estado de salud y en la observación de los vínculos familiares existentes y de los cuidados dispensados por la familia a lo largo del tiempo. COMENTARIOS: Accidentes y violencia son causas frecuentes de lesiones físicas en niños, siendo el diagnóstico diferencial de ambos un desafío para los profesionales, especialmente frente a cuadros clínicos raros en pacientes que todavía no verbalizan. La actuación de equipo multidisciplinario con profesionales instrumentalizados para ese tipo de atención ayuda en la conducción adecuada, garantizando la protección del niño y la creación de vínculo con la familia, lo que es esencial para un posterior seguimiento que haga viable la observación continuada del caso...

ABSTRACT

O objetivo do estudo foi analisar o efeito do flushing, do protocolo hormonal para sincronização de estro e da IATF sobre o desempenho reprodutivo de ovelhas Morada Nova (MN) e Santa Inês (SI). Foram utilizadas 27 ovelhas SI e 24 ovelhas MN suplementadas com concentrado (1% do peso vivo, em média) durante 75 dias de estação reprodutiva. Após 30 dias de suplementação, as ovelhas foram sincronizadas com protocolo hormonal (PH) à base de progestágeno, eCG e cloprostenol. A observação de estro foi realizada após 12, 24, 36 e 48 horas do término do PH, com o auxílio de dois rufiões, e a IATF foi realizada aproximadamente 55 horas após o final do PH. Do 20º ao 45º dia após o início do PH, realizou-se o repasse com um reproduto Dorper. O diagnóstico de prenhez foi realizado 70 dias após a IATF. Foi analisado o peso, escore da condição corporal (ECC), taxa de apresentação de estro, taxa de prenhez e prolificidade, testando-se os efeitos da raça, semana de suplementação (SS) e classe de ECC. O peso e ECC das ovelhas variaram em função da SS. Foi observada taxa de estro de 88,2%, sendo que 43,2% das ovelhas apresentaram estro até 24 horas do final do PH. A taxa de prenhez por IATF foi de 31,4% e a de prenhez após repasse foi de 50,0%, sendo que a classe de ECC interferiu nas taxas de prenhez. Obteve-se maior porcentagem de partos múltiplos de ovelhas prenhes por IATF do que por monta natural no repasse. Conclui-se que o flushing resultou em ganho de peso e aumento do ECC, o que garantiu a padronização do rebanho para a estação reprodutiva e, consequentemente, melhorou o desempenho reprodutivo. O PH utilizado aumentou a prolificidade e adiantou o início do estro; porém, não foi eficiente na sincronização de ovelhas deslanadas...


The aim of this study was to analyze the effect of flushing on the reproductive performance of Morada Nova (MN) and Santa Inês (SI) ewes submitted to fixed time artificial insemination (TAI). Twenty seven SI and 24 MN supplemented with concentrate (1% of live weight, on average), for 75 days during the breeding season. After 30 days of supplementation, ewes were synchronized with the aid of a hormonal protocol (HP) based on progesterone, eCG and cloprostenol. The estrus observation was conducted at 12, 24, 36 and 48 h after the end of HP with the aid of two ruffians. TAI was done 55 h after the end of HP. From 20 to 45 days after the beginning of the HP ewes were exposed to rams (natural breeding). The pregnancy diagnosis was evaluated 70 days after TAI. We analyzed the weight, body condition score, estrus rate, pregnancy rate and prolificacy testing the effects of race, week of supplementation and body condition score class. The weight and body conditions of ewes varied according to the week of supplementation, with higher values in the first two weeks following TAI. The estrus rate was 88.2% and 43.2% of the ewes showed estrus up to 24 hours of the end of the HP. The pregnancy rate per TAI was 31.3% and the pregnancy rate after natural breeding was 50.0%. It was observed that body condition score classes interfered in pregnancy rates. There was a higher percentage of multiple births by pregnancy by TAI than by natural breeding. It was concluded that the flushing resulted in weight gain and better body conditions ensuring the standardization of the herd for breeding season, which therefore improved reproductive performance. The HP used advanced the onset of estrus and increased prolificacy, but was inefficient in the synchronization of woolless sheep...

ABSTRACT

Objetivou-se avaliar a influência do nível de suplementação com concentrado sobre o perfil hematológico de ovelhas Morada Nova no terço final da gestação e puerpério, bem como comparar os valores obtidos em diferentes categorias (fêmeas em gestação, puerpério e cordeiros). Utilizaram-se 11 ovelhas, aos 75 últimos dias de gestação e nos primeiros 75 dias de lactação, e oito cordeiros progênie das ovelhas, distribuídas em delineamento inteiramente casualizado em arranjo de parcelas subdivididas no tempo. Durante o período experimental, os animais permaneceram em pastagem de Andropogon gayanus, sendo recolhidos ao final da tarde, quando recebiam suplementação concentrada com 19,17% de proteína bruta. As amostras de sangue foram colhidas desde o 75º dia de gestação até o desmame, aos 75 dias de lactação, a cada quatorze dias. O sangue foi colhido sempre pela manhã, antes de os animais serem liberados para o pasto, por punção da veia jugular, para a realização do hemograma. Os diferentes níveis de suplementação não influenciaram (P>0,05) o perfil eritrocitário e leucocitário das ovelhas. A categoria animal influenciou (P<0,05) o teor de hemoglobina e o número de eritrócitos. Os valores médios de hemoglobina não difeririam (P>0,05) entre fêmeas gestantes (7,74g/dL) e puerperais (7,67g/dL), bem como a contagem total de hemácias dos cordeiros (8,14x10(6)/µL) e das fêmeas em puerpério (9,16 x 10(6)/µL). Os valores médios do hematócrito, volume corpuscular médio, concentração de hemoglobina corpuscular média e proteína total não diferiram estatisticamente (P>0,05) entre as ovelhas; no entanto, observaram-se maiores níveis para os cordeiros. O número de leucócitos totais foram superiores (P<0,05) nas ovelhas gestantes e puerperais em relação aos cordeiros. A suplementação concentrada não influenciou o perfil hematológico dos animais, porém a categoria animal exerceu influência sobre os parâmetros hematológicos eritrocitários e leucocitários.


This research was carried out to evaluate the influence of supplementation with concentrate on hematological profile of Morada Nova sheep in last third of pregnancy and postpartum, as well as comparing the values obtained in different categories (pregnant females, postpartum, and lambs). Eleven ewes it the last 75 days of pregnancy and the first 75 days of lactation and eight lambs born from the ewes allotted in completely randomized design and split-plot arrangement in time were used. During the experimental period, the animals remained in Andropogon gayanus pasture. Late in the afternoon they returned to the center of management to receive the concentrate supplementation with 19.17% of crud protein. Blood samples were collected from the 75th day of pregnancy to weaning at 75 days of lactation, every fourteen days. Blood samples were taken always in the morning, before the animals were released into the pasture, by puncturing the jugular vein, for complete blood count. Neither the erythrocyte profile nor the leukocyte profile was affected by the different levels of supplementation (P>0.05). The animal category had a significant effect (P<0.05) on hemoglobin and erythrocyte number. The mean hemoglobin values did not differ (P>0.05) between pregnant ewes (7.74 g/dL) and ones in postpartum (7.67g/dL) as well as the total count of red blood cells of the lambs (8.14 x 106/µL) did not differ (P>0.05) from females in postpartum (9.16 x 106/µl). When comparing between pregnant and postpartum ewes for the mean hematocrit values, mean corpuscular volume, mean corpuscular hemoglobin concentration and total protein did not differ (P>0.05). The highest values were observed in these animals. The total white cell count was higher (P<0.05) in pregnant and postpartum ewes than lambs. The concentrate supplementation did not affect the blood profile of animals, but the animal category exerted influence on erythrocyte and leukocyte hematological parameters.

ABSTRACT

A erva-cidreira [Lippia alba (Mill.) N. E. Br.] é uma espécie da família Verbenaceae amplamente utilizada pela população brasileira, devido às propriedades calmante, espasmolítica suave, analgésica, sedativa, ansiolítica e levemente expectorante. Para implantação do experimento foi produzido composto orgânico de capim elefante + esterco, na proporção de 70% de material vegetal e 30% de esterco, sem inoculação e inoculados com os isolados de actinomicetos do gênero Streptomyces: AC16; AC26; AC92 e AC103. Os compostos foram acondicionados em sacos de polietileno contendo 10,0 kg de solo adicionados na proporção equivalente a 20 t ha-1 e foram reaplicados logo após a primeira colheita. As colheitas da parte aérea foram realizadas aos 75 e 165 dias após o transplante. As raízes foram colhidas logo após a segunda colheita. Os tratatamentos com adubação orgânica promoveram aumento médio na produção de biomassa da erva-cidreira de 184, 83, 125, 115 e 122% para biomassa seca da parte aérea (MSPA) na primeira colheita, de MSPA na segunda colheita, biomassa seca total da parte aérea (MSTPA), biomassa seca de raiz (MSR) e biomassa seca total da cultura (MST), respectivamente, quando comparados com o tratamento controle, porém não houve efeito da inoculação de actinomicetos no composto orgânico. Nas condições em que este estudo foi realizado foi possível concluir que a adubação com composto orgânico de capim elefante influenciou positivamente a produção de biomassa seca da L. alba, mas a inoculação dos compostos com actinomicetos não exerceu influência.


L. alba is a species of the family Verbenaceae widely used by the Brazilian population, because of the soothing, gentle antispasmodic, analgesic, expectorant, sedative, anxiolytic and smoothly. For the implementation of the experiment produced organic compound of elephant grass (Pennisetum purpureum Shum.) + manure at 70% plant material and 30% manure, uninoculated and inoculated with the actinomycete Streptomyces genus, AC16, AC26, AC92 and AC103. The compounds were placed in polyethylene bags containing 10.0 kg of soil added in a proportion equivalent to 20 t ha-1 and re-apply after the first harvest. The harvests of the shoots were taken at 75 and 165 days after transplantation. The roots were harvested after the second harvest. Dealing with organic fertilization promoted the average increase in biomass production of lemon grass 184, 83, 125, 115 and 122% for the dry stem biomass (MSPA) in the first harvest, second harvest of MSPA, total shoot biomass (MSTPA), dry biomass of the root (MSR) and the total crop biomass (MST), respectively, compared with the control, but no effect of inoculation of actinomycetes in compost. Under the conditions of this study was conducted, it was concluded that the organic compound fertilizer with elephant grass positively influenced the production of dry biomass of L. alba, but the injection of the compounds of the actinomycetes, without influence.

ABSTRACT

A partir de um estudo sobre a anatomia foliar de Aniba firmula (Nees & C. Mart.) Mez (Lauraceae), objetivou-se identificar caracteres anatômicos que possam auxiliar, de forma efetiva, sua morfodiagnose, tendo em vista que as espécies pertencentes a esse gênero são consideradas de difícil identificação devido à semelhança entre elas. Para realização do trabalho, foram utilizados métodos usuais em Anatomia Vegetal. Os resultados revelaram caracteres que podem ser considerados diagnósticos para a espécie, tais como: presença de tricomas tectores; estômatos paracíticos classificados como sendo do tipo "graminoide"; cristais prismáticos em células parênquimáticas no pecíolo; tricoesclereídes e braquiesclereides na lâmina foliar; sistema vascular em arco, com extremidades voltadas para o centro nas porções proximal e mediana do pecíolo e em arco com extremidades eretas na porção distal; sistema vascular na forma de arco com extremidades eretas, "V" aberto ou traço contínuo na nervura mediana; células oleíferas no mesofilo; padrão de venação camptódromo-broquidódromo, com venação marginal do tipo fimbrial. A análise de indivíduos ocorrentes em diferentes localidades foi determinante para a escolha de caracteres que não variam em decorrência das condições ambientais distintas.


The study about the leaf anatomy of Aniba firmula (Nees & C. Mart.) Mez (Lauraceae), aimed to identify anatomical characters that assists in its diagnosis, in view of the difficulty to identificate the Aniba species by being considered very similars. To realizate this research, usual methods in Plant Anatomy were applied. The obtained results considered like diagnostic characters were the presence of non glandular trichomes; paracitic stomata like "graminoid type"; prismatic crystals in parenchymatic cells, trichosclereids and brachisclereids; vascular system in arc form, with borders revolved to the center in the basal and middle region and "U" shaped in distal region of the petiole, midrib in "U" or "V" shaped or simple trace form; oil cells in the mesophyll and camptodromous-broquidodromous venation pattern with fimbrial margin. The analysis of specimens occuring in different towns was crucial to choose the characters that´s not change because of the different environmental conditions.

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 percent more than SC/SC-Sed; P < 0.0001), and exercise reduced it by 23 percent (P < 0.0001). Hepatic enzymes ALP (+80 percent), ALT (+100 percent) and AST (+70 percent) 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 percent; P < 0.001). Pancreatic islets, adipocytes and liver structure were greatly affected by HF, ultimately resulting in islet â-cell hypertrophy and severe liver steatosis. The HF group had larger islets than the SC/SC group (+220 percent; 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

Visceral leishmaniasis (VL) is a serious tropical disease that affects approximately 500 thousand people worldwide every year. In the Americas, VL is caused by the parasite Leishmania (Leishmania) infantum chagasi mainly transmitted by the bite of the sand fly vector Lutzomyia longipalpis. Despite recent advances in the study of interaction between Leishmania and sand flies, very little is known about sand fly protein expression profiles. Understanding how the expression of proteins may be affected by blood feeding and/or presence of parasite in the vector's midgut might allow us to devise new strategies for controlling the spread of leishmaniasis. In this work, we report the characterization of a vacuolar ATPase subunit C from L. longipalpis by screening of a midgut cDNA library with a 220 bp fragment identified by means of differential display reverse transcriptase-polymerase chain reaction analysis. The expression of the gene varies along insect development and is upregulated in males and bloodfed L. longipalpis, compared to unfed flies.

ABSTRACT

The brown algae Padina gymnospora contain different fucans. Powdered algae were submitted to proteolysis with the proteolytic enzyme maxataze. The first extract of the algae was constituted of polysaccharides contaminated with lipids, phenols, etc. Fractionation of the fucans with increasing concentrations of acetone produced fractions with different proportions of fucose, xylose, uronic acid, galactose, and sulfate. One of the fractions, precipitated with 50 percent acetone (v/v), contained an 18-kDa heterofucan (PF1), which was further purified by gel-permeation chromatography on Sephadex G-75 using 0.2 M acetic acid as eluent and characterized by agarose gel electrophoresis in 0.05 M 1,3 diaminopropane/acetate buffer at pH 9.0, methylation and nuclear magnetic resonance spectroscopy. Structural analysis indicates that this fucan has a central core consisting mainly of 3-ß-D-glucuronic acid 1-> or 4-ß-D-glucuronic acid 1 ->, substituted at C-2 with alpha-L-fucose or ß-D-xylose. Sulfate groups were only detected at C-3 of 4-alpha-L-fucose 1-> units. The anticoagulant activity of the PF1 (only 2.5-fold lesser than low molecular weight heparin) estimated by activated partial thromboplastin time was completely abolished upon desulfation by solvolysis in dimethyl sulfoxide, indicating that 3-O-sulfation at C-3 of 4-alpha-L-fucose 1-> units is responsible for the anticoagulant activity of the polymer.

ABSTRACT

Investigamos a presenca de sinais neurologicos menores (SNM) em pacientes com transtorno obsessivo compulsivo (TOC), de "início precoce" e "início tardio" e sua correlaçao com características clínicas e terapêuticas. Vinte pacientes com TOC, sendo 10 de início precoce (idade média de início=11.10 anos) e 10 de início tardio (idade média de início de 41.70 anos) foram avaliados com as escalas Y-BOCS, CGI e uma escala elaborada pelos autores para avaliaçäo de SNM. Após a avaliaçäo neurológica, os pacientes foram tratados com inibidores da recaptaçäo da serotonima por 10 semanas. Dentre os 20 pacientes examinados,foram identificados um ou mais SNM em 12 (60 por cento), sendo seis pacientes pertencentes ao subgrupo de TOC de início precoce (n=10) e seis pacientes pertencentes ao subgrupo de TOC de início precoce (n=10) e seis pacientes pertencentes ao subgrupo de TOC de início tardio (n=10). Os sinais neurológicos mais comuns foram alteraçöes de fala/articulaçäo (em 36,4 por cento) e a impersistência de membros superiores (em 21,1 por cento). A presença de alteraçöes motoras as exame de SNM se correlacionou significativamente com maior gravidade das compulsöes (p=0,004). A presença de SNM näo se correlacionou com a resposta terapêutica. Concluímos que SNM säo frequentemente encontrados em pacientes com TOC, mas näo diferem em frequência entre o subgrupo de início precoce e de início tardio. A presença de SNM de motilidade se correlacionou com compulsöes mais graves

ABSTRACT

Utilizou-se a associaçäo de cloridrato de tiletamina (125mg) e cloridrato de zolazepam (125mg) diluídos em água destilada (10ml) como tranqüilizante e anestésico em 38 animais pertencentes à espécies Saguinus imperator imperator (N= 21), Saguinus fuscicollis weddeli (N= 15) e Cebuella pygmea (N=2). Indivíduos de ambos os sexos, com pesos entre 130 e 520g, receberam doses de 0,02ml (1,11mg/kg) a 0,15ml (8,33mg/kg) pela via intramuscular. Na maioria dos casos ocorreu anestesia. Os animais foram libertados no mesmo dia da captura, após recuperaçäo pós-anestésia. Näo ocorreu efeito colateral aparente sobre os fetos de duas fêmeas gestantes. Apesar da morte de um animal jovem, os resultados foram considerados satisfatórios na tranqüilizaçäo e anestesia de calitriquídeos
