ABSTRACT A 2-year-old English bulldog presented history of recurrent lower urinary tract disease, refractory to treatment. The Complete Blood Count revealed lymphopenia, hyperproteinemia, and hyperglobulinemia, while urinalysis indicated leukocyturia and bacteriuria. On the abdominal ultrasound, the bladder had a focal wall thickening in its cranial portion, as well as irregular echogenicity and internal margins. A bladder surgical biopsy was performed, indicating the presence of follicular cystitis. Clinical signs disappeared after treatment with a combination of amoxicillin and clavulanic acid, NSAIDs, supplementation with cranberry extract associated with cat's claw (Uncaria tomentosa). Clinical follow-up 12 months after surgery showed remission at all clinical signs. Follicular cystitis in dogs was reported only once worldwide, this case report is the first in Brazil; thus, it may be considered in the differential diagnosis for patients with refractory and recurrent lower urinary tract disease. 2yearold yearold 2 year old disease lymphopenia hyperproteinemia hyperglobulinemia bacteriuria ultrasound portion margins performed acid NSAIDs cats cat s Uncaria tomentosa. tomentosa . tomentosa) followup follow up 1 worldwide Brazil thus

RESUMO Um Bulldog Inglês de 2 anos apresentou história clínica de doença recorrente do trato urinário inferior, refratária ao tratamento. O hemograma revelou uma discreta linfopenia, hiperproteinemia e hiperglobulinemia. Já a urinálise apontou leucocitúria e bacteriúria. Na ultrassonografia, a bexiga apresentava espessamento focal da parede da bexiga em porção cranial, ecogênica e margens internas irregulares. A biópsia cirúrgica da bexiga foi compatível com cistite folicular. Os sinais clínicos desapareceram após o tratamento com uma combinação de amoxicilina - ácido clavulânico, AINEs, suplementação alimentar de extrato de cranberry associado a unha de gato (fitoterápico da planta Uncaria tomentosa). O acompanhamento, 12 meses após a cirurgia, confirmou que o cão estava livre de sinais clínicos. A cistite folicular foi relatada apenas em 1 cão no mundo, sendo esse considerado o primeiro relato no Brasil. Essa enfermidade deve ser considerada um diferencial para pacientes com doença refratária do trato urinário inferior de longa data. linfopenia hiperglobulinemia bacteriúria ultrassonografia cranial irregulares clavulânico AINEs fitoterápico tomentosa. tomentosa . tomentosa) acompanhamento cirurgia mundo Brasil data

RESUMO No presente trabalho, foi avaliado o efeito imunomodulador de diferentes doses de talidomida em macrófagos associados ao tumor (TAMs), em um modelo murino de câncer de mama. Camundongos foram inoculados com células 4T1, na região do flanco esquerdo, e tratados com talidomida, uma vez ao dia, nas doses de 50, 100 e 150mg/k, por massa corporal, do quinto dia ao 28º dia de inoculação tumoral. Os tumores foram medidos, o índice de proliferação celular e a contagem de TAMs foram avaliados nos tumores primários e nos pulmões com metástases. Além disso, a taxa de metástases pulmonares também foi avaliada. A talidomida na dose de 150mg/kg diminuiu significativamente o crescimento tumoral, o índice de proliferação celular e a infiltração de TAMs nos tumores primários. Por outro lado, maior número de TAMs e menor índice de proliferação celular foram observados nos pulmões metastáticos, em camundongos tratados com 150mg/kg de talidomida. Ademais, a talidomida na dose de 150mg/kg diminuiu significativamente os nódulos metastáticos nos pulmões. Os resultados demonstraram que o tratamento com talidomida diminuiu o crescimento tumoral e as metástases pulmonares em camundongos, associado com diferentes efeitos na infiltração de TAMs nesses locais.

ABSTRACT The present work evaluated the immunomodulatory effect of thalidomide (Thal) at different doses on tumor-associated macrophages (TAMs) using a mouse model of human breast cancer. Mice were inoculated with 4T1 cells in the left flank and treated with Thal once a day at concentrations of 50, 100, and 150mg/kg body weight from the 5th day until the 28th day of tumor inoculation. The tumors were sized, proliferation index and TAMs count were evaluated in primary tumors and metastatic lungs. In addition, the metastasis rate was evaluated in the lungs. Thal at 150mg/kg significantly decreased tumor growth, proliferation index, and TAMs infiltration in primary tumors. Conversely, a higher number of TAMs and lower proliferation index were observed in metastatic lungs in mice treated with 150mg/kg of Thal. Furthermore, Thal at 150mg/kg significantly decreased the metastatic nodules in the lungs. Our findings demonstrated that Thal treatment considerably decreased the primary tumor and lung metastasis in mice associated with different TAM infiltration effects in these sites.

Resumo No presente trabalho, os efeitos de dois diferentes produtos foram avaliados - Metarril® SP Organic (conídios secos) e Metarril® SC Organic (conídios concentrados em óleo vegetal) - para ovos, larvas e fêmeas ingurgitadas de Rhipicephalus microplus. Três concentrações (108, 107 e 106 conídios mL-1) para cada produto foram preparadas em água + Tween® 80 0,1% (v/v); os bioensaios foram realizados para todos os estágios de R. microplus por imersão nas suspensões (Metarril® SP) ou formulações (Metarril® SC). Metarril® SP não afetou os parâmetros biológicos das fêmeas, demonstrando assim baixa eficácia; para ovos e larvas, foram observadas discretas diminuições na eclodibilidade e na população de larvas. Apesar de um atraso na germinação, Metarril® SC apresentou melhores resultados; para as fêmeas, foram detectadas reduções no Peso da Massa de Ovos (PMO) e no Índice de Produção de Ovos (IPO). Para os ovos, a concentração de 108 conídios mL-1 aumentou o Período de Incubação (PI), reduziu o Período de Eclosão (PE) e também o da eclodibilidade em até 61%; para larvas, 107 e 108 conídios mL-1 atingiram 99,6 e 100% de mortalidade larval, respectivamente, 10 dias após a exposição fúngica. Com isso, estudos adicionais que envolvem o uso de formulações à base de óleo para carrapatos, como Metarril® SC, precisam ser realizados, especialmente para controlar os estágios mais suscetíveis (ovos e larvas).

Abstract The effects of two different products - Metarril® SP Organic (dry conidia) and Metarril® SC Organic (emulsifiable concentrated conidia in vegetable oil) - on eggs, larvae and Rhipicephalus microplus engorged females were here explored. Three concentrations (108, 107, and 106 conidia mL-1) for both products were prepared in water + 0.1% Tween® 80 (v/v); afterward, bioassays were carried out for all R. microplus stages by immersion in suspensions (Metarril® SP) or formulations (Metarril® SC). Metarril® SP suspensions showed low efficacy and did not affect biological parameters of treated engorged females; for eggs and larvae, only slight decreases in hatchability and larvae population were observed. Despite a delay in germination, Metarril® SC presented better results; for females, reductions in Egg Mass Weight (EMW) and Egg Production Index (EPI) were reported. On eggs, 108 conidia mL-1 increased Incubation Period (IP), shortened Hatching Period (HP) and decreased hatchability by up to 61%; for larvae, 107 and 108 conidia mL-1 reached 99.6 and 100% larval mortality respectively, 10 days after fungal exposure. Thus, further studies involving the use of oil-based formulations for ticks such as Metarril® SC need to be performed, especially to control the most susceptible stages (eggs and larvae).

ABSTRACT The quality of sesame (Sesamum indicum L.) seeds is directly influenced by their physical characteristics, which are seldom studied notwithstanding their extreme importance in the entire production chain. Therefore, the objective of this study was to quantify the physical properties of two types of sesame seeds, collected at three points in the plant with different maturation levels, measured with digital caliper, and to evaluate the feasibility of using a digital image to determine their physical characteristics. The seeds were initially evaluated for water content and mass of 1000 seeds, and later with the data of the characteristic dimensions A (length), B (width), and C (thickness), obtained by a caliper and digital images, we determined their sphericity, circularity, projected area, and geometric diameter. We observed that water content did not affect the physical properties of the cream (CNPA G4) and black sesame cultivars. In addition, seeds of the black cultivar presented higher results than the seeds of the cream cultivar for the mass of 1000 seeds (2.7 ± 0.08 g), sphericity (58.8 ± 0.47%), projected area (4.03 ± 0.12 mm2), and geometric diameter (1.65 ± 0.03 mm). Seed batches harvested after 70% maturation had the highest mass of 1000 seeds (2.7 ± 0.12 g). The results of the physical analyses of sesame seeds performed with caliper and digital image are equivalent, which shows that digital images can be used as tools to obtain the physical properties of seeds.

Modifications in life-style and/or pharmacotherapies contribute to weight loss and ameliorate the metabolic profile of diet-induced obese humans and rodents. Since these strategies fail to treat hypothalamic obesity, we have assessed the possible mechanisms by which duodenal-jejunal bypass (DJB) surgery regulates hepatic lipid metabolism and the morphophysiology of pancreatic islets, in hypothalamic obese (HyO) rats. During the first 5 days of life, male Wistar rats received subcutaneous injections of monosodium glutamate (4 g/kg body weight, HyO group), or saline (CTL). At 90 days of age, HyO rats were randomly subjected to DJB (HyO DJB group) or sham surgery (HyO Sham group). HyO Sham rats were morbidly obese, insulin resistant, hypertriglyceridemic and displayed higher serum concentrations of non-esterified fatty acids (NEFA) and hepatic triglyceride (TG). These effects were associated with higher expressions of the lipogenic genes and fatty acid synthase (FASN) protein content in the liver. Furthermore, hepatic genes involved in β-oxidation and TG export were down-regulated in HyO rats. In addition, these rats exhibited hyperinsulinemia, β-cell hypersecretion, a higher percentage of islets and β-cell area/pancreas section, and enhanced nuclear content of Ki67 protein in islet-cells. At 2 months after DJB surgery, serum concentrations of TG and NEFA, but not hepatic TG accumulation and gene and protein expressions, were normalized in HyO rats. Insulin release and Ki67 positive cells were also normalized in HyO DJB islets. In conclusion, DJB decreased islet-cell proliferation, normalized insulinemia, and ameliorated insulin sensitivity and plasma lipid profile, independently of changes in hepatic metabolism.

Cien. Inv. Agr. 43(3):442-451. Wheat (Triticum aestivum L.) is a cereal used in food and feed for its nutritional properties. For nitrogen and potassium management, efficient use of water is required for greater availability and transportation of these nutrients. The objective of this study was to evaluate the effect of combinations of nitrogen and potassium doses in production, nutrition and water use efficiency in wheat. The experiment was held in a greenhouse with 8-dm³ pots using Oxisol collected at a depth of 0-0.2 m under Cerrado vegetation. Base saturation was raised to 60%. The experimental design was a randomized block in a 5x5 factorial arrangement with five doses of nitrogen (0, 100, 200, 300 and 400 mg dm-3) and potassium (0, 90, 180, 270, 360 mg dm-3) with four replications. Soil moisture was maintained by an auto-irrigation system (3 kPa pressure). The experiment was collected at 95 days after plant emergence. We evaluated the dry mass of ears, shoots and roots, the total dry matter, nitrogen and potassium in grains, and the consumption and efficiency in water use. An analysis of variance and regression test at 5% probability was conducted using SAS statistical software (SAS Institute, Inc., Cary, North Carolina). The nitrogen and potassium alone increased the dry mass of ears by 31.47% and 20.91%, respectively. There was an interaction of nutrients on the dry mass of the shoots and the total dry matter. Potassium increases the concentration of nitrogen. Nitrogen and potassium promote gains in production, nutrition and water use efficiency.

A cutia (Dasyprocta sp.) é um roedor silvestre com distribuição mundial. Atualmente, além de importante papel ecológico que exerce, está sendo utilizada como modelo em experimento animal. Estudos sobre a morfologia destes animais são importantes porque podem ser uma alternativa para o estudo de diversos processos patológicos, além de contribuirem para a preservação da espécie. A laringe é um órgão localizado entre a faringe e a traqueia, no qual está envolvido nas funções de respiração, deglutição e fonação. O presente estudo propôs realizar uma descrição morfológica macroscópica e microscópica da laringe da cutia. Para tanto, foram utilizadas quinze cutias pertencentes ao Centro de Ciências Agrárias da Universidade Federal do Piauí e provenientes do Núcleo de Estudos e Preservação de Animais Silvestres com licença do IBAMA (Nº 02/08-618, CTF Nº 474064). Todos os animais foram identificados, promovida a sexagem e, posteriormente, a laringe acessada e dissecada sendo os fragmentos cartilagíneos encaminhados para rotina histológica e corados pelo método de hematoxilina-eosina. As lâminas obtidas foram visualizadas em microscopia óptica de luz e foto documentadas. A laringe da cutia apresenta cinco cartilagens, com ausência da cartilagem cuneiforme e presença da incisura caudal na cartilagem tireoide. O tecido epitelial da laringe varia de epitélio estratificado pavimentoso queratinizado à não queratinizado e ciliado com células caliciformes.

The agouti (Dasyprocta sp.) is a wild rodent with worldwide distribution. Besides its ecological role, agouti is used as a model in animal experimentation. Studies on the morphology of agouti are important because they can be an alternative for the study of various pathological processes and contribute to the preservation of the species. The larynx, located between the pharynx and trachea, is involved in the functions of breathing, swallowing and speech. This study aimed to perform a macroscopic and microscopic morphology of the larynx of agouti. To this end, we used fifteen agoutis belonging to the Centre of Agricultural Sciences, Federal University of Piauí, and from the Center for Study and Preservation of Wild Animals with license of IBAMA (No. 02/08-618, CTF No. 474064). All animals were identified according to their gender, the larynx was dissected and cartilaginous fragments were sent for routine histology and stained with hematoxylin-eosin. The slides obtained were viewed in light microscopy and photo documented. The larynx of agouti has five cartilages, without the cuneiform cartilage but presence of the thyroid cartilage notch. The epithelial tissue of the larynx varies from stratified squamous epithelium to keratinized and non-keratinized ciliated caliciforme cells.

Estudou-se a distribuição e diversidade de espécies de Anopheles em 123 municípios do Estado do Maranhão, Brasil. O método básico foi a captura de fêmeas dentro e nos arredores das habitações humanas, em intervalos compreendidos entre 18h e 6h, no período de janeiro de 1992 a dezembro de 2001. Foram capturados 84.467 exemplares distribuídos em 24 espécies, com o predomínio de A. triannulatus sensu lato (20.788), A. darlingi (19.083), A. nuneztovari (16.884), A. albitarsis s.l. (14.352), A. aquasalis (8.202) e A. evansae (2.885). As outras 18 espécies juntas representaram apenas 2,7%. As espécies encontradas no maior número de municípios foram: A. albitarsis s.l. (109 municípios), A. triannulatus s.l. (106), A. nuneztovari (93), A. darlingi (87) e A. evansae (64). A riqueza e a ampla distribuição das espécies de anofelinos no Maranhão concordam com a posição geográfica do estado, entre as macrorregiões que caracterizam o Brasil, resultando em uma fauna mista, com elementos representativos dessas regiões.

We studied the distribution and diversity of Anopheles species in 123 counties (municipalities) in the State of Maranhão, Brazil. The basic method consisted of capturing female specimens inside and around human dwellings between 6 PM and 6 AM from January 1992 to December 2001. A total of 84,467 specimens belonging to 24 species were captured, with a predominance of A. triannulatus sensu lato (20,788), A. darlingi (19,083), A. nuneztovari (16,884), A. albitarsis s.l. (14,352), A. aquasalis (8.202), and A. evansae (2,885). The other 18 species together accounted for only 2.7% of the total. The species found in the most counties were A. albitarsis s.l. (109 counties), A. triannulatus s.l. (106), A. nuneztovari (93), A. darlingi (87), and A. evansae (64). The richness and wide distribution of anopheline species in Maranhão agree with the State's geographic position among Brazil's macro-regions, resulting in a mixed fauna with representative elements from these regions.

Os cultivares de soja Santa Rosa e UFV-1 foram cultivados em solução nutritiva deficiente em B, Cu ou Zn. As plantas carentes em B não completaram o ciclo, enquanto as demais o fizeram. A carência de Cu afetou a produção de matéria seca e a de vagens mais que a falta de Zn. Quantitativamente, as deficiências induzidas afetaram a variedade UFV - 1 mais que a Santa Rosa.

Two soybean varieties were grown in nutrient solution either in the presence on in the absence of B, Cu and Zn. Symptoms of deficiency were observed. Dry matter production and yield data were recorded. Leaf analyses were made in the end of the pod filling period (except in the case of the minus B treatment in which plants failed to produce grains). Main conclusions were the following: (1) lack of B in the substrate affected dry matter production more than the deficiencies of Cu and Zn; (2) Cu deficiency reduced growth and yield formation more than the lack of Zn; (3) symtoms of deficiency are in agreement with those already described; (4) variety UFV-1 seems more sensitive to the deficiency of micronutrients than Santa Rosa; (5) leaf levels of B and Zn indicative of adequate nutritional status seem to be different for the two varieties.
