Pesticides have been pointed out as hormone disruptors and may significantly affect the prognosis of hormone-dependent diseases such as breast cancer (BC). Here, we investigated the impact of occupational pesticide exposure on systemic cortisol levels in female rural workers diagnosed with BC. Occupational exposure was assessed by interviews with a standardized questionnaire. Plasma samples (112 from pesticide-exposed women and 77 from unexposed women) were collected in the afternoon, outside the physiological cortisol peak, and analyzed by a chemiluminescent paramagnetic immunoassay for the quantitative determination of cortisol levels in serum and plasma. The results from both groups were categorized according to patients' clinicopathological and exposure data. BC pesticide-exposed women presented higher levels of cortisol than the unexposed. Higher cortisol levels were also detected in the exposed group with more aggressive disease (triple-negative BC), with tumors over 2 cm, with lymph node metastases, and with high risk of disease recurrence and death. These findings demonstrated that there is an association between pesticide exposure and BC that affected cortisol levels and correlated to poor disease prognosis. hormonedependent dependent .

RESUMO O objetivo deste trabalho foi diagnosticar o agente causador da mortalidade de carpas (Cyprinidae) em um lago artificial utilizado para recreação em Jaraguá do Sul, estado de Santa Catarina, em fevereiro de 2018. Os peixes apresentavam sintomas, incluindo ulcerações na pele, hemorragia na superfície do corpo, perda de escama e elevada produção de muco. Por meio do perfil proteômico, pela técnica de MALDI-TOF, três isolados bacterianos foram identificados como Aeromonas veronii, A. hydrophila e Citrobacter freundii. Além disso, no raspado do muco, foi observado grande número do ectoparasito Argulus. Foi realizada uma coleta de sangue para verificar o perfil hematológico dos animais e constatou-se uma diminuição na porcentagem de hematócrito, no número de eritrócitos e na contagem diferencial dos leucócitos. Esses achados indicam que a infecção por Argulus aumenta a suscetibilidade da carpa a doenças bacterianas bem como contribui para a supressão do sistema imunológico inato e o consequente aumento da mortalidade.

ABSTRACT The aim of this study was to diagnose the causative agent of carp (Cyprinidae) mortality in an artificial lake used for recreation in Jaraguá do Sul, state of Santa Catarina, in February 2018. The fish showed symptoms, including skin ulceration, hemorrhages on the surface of the body, loss of scale and increased mucus production. Through the proteomic profile, using the MALDI-TOF technique, three bacterial isolates were identified as Aeromonas veronii, A. hydrophila and Citrobacter freundii. In addition, in the mucus scraping, a large number of the ectoparasite Argulus was observed. A blood collection was carried out to verify the hematological indices of the animals and a decrease in the the hematocrit value, erythrocyte count, and differential leukocyte count was observed. These findings indicate that Argulus infection increases the carp’s susceptibility to bacterial diseases and contributes to the suppression of the innate immune system and consequent increase in mortality.

The misuse of anabolic androgenic steroid associated or not with physical workouts disrupts gastrointestinal (GI) function homeostasis. Our goal was to investigate the effects of nandrolone decanoate (ND) and moderate swimming on the GI transit of solid meals, GI motor contractility, and intestinal histology in rats. Male Wistar rats were allocated to four groups that received intramuscular injections of ND (5.0 mg/kg) or vehicle (60.0 µL) and were submitted or not to swimming sessions (60 min, 5% body weight overload) for 4 weeks. Gastric emptying, intestinal transit, in vitro GI contractility, intestinal morphometry, and duodenal mucosal mast cells were evaluated in all experimental groups. ND treatment accelerated gastric emptying, slowed small intestine transit time, enhanced gastric carbachol-mediated reactivity, decreased crypt depth and villus height, reduced mucosal thickness, and increased the circular and longitudinal muscle layer thickness of the duodenum in sedentary rats. Moderate exercise accelerated intestinal transit time and reduced submucosa thickness. In vehicle-treated animals, a strong negative correlation was found between intestinal transit and mucosal mast cells, which was reversed by ND treatment. Combining ND treatment and swimming accelerated gastric emptying, increased duodenal cholinergic reactivity, inhibited the sodium nitroprusside relaxing response, increased the number of duodenal mast cells, decreased villus height, and increased the thickness of all muscle layers. ND changed the morphological and functional properties of the GI tract over time, with intense dysmotility, especially in sedentary animals, but moderate exercise seemed to have played a compensatory role in these harmful effects in the gut.

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Abstract Geoprocessing techniques are generally applied in natural disaster risk management due to their ability to integrate and visualize different sets of geographic data. The objective of this study was to evaluate the capacity of classification and regression tree (CART) to assess fire risk. MCD45A1 product of the burnt area, relative to a 16-year period (2000-2015) was used to obtain a fire occurrence map, from center points of the raster, using a kernel density approach. The resulting map was then used as a response variable for CART analysis with fire influence variables used as predictors. A total of 12 predictors were determined from several databases, including environmental, physical, and socioeconomic aspects. Rules generated by the regression process allowed to of define different risk levels, expressed in 35 management units, and used to produce a fire prediction map. Results of the regression process (r = 0.94 and r² = 0.88) demonstrate the capability of the CART algorithm in highlighting hierarchical relationships among predictors, while the model’s easy interpretability provides a solid basis for decision making. This methodology can be expanded in other environmental risk analysis studies and applied to any area of the globe on a regional scale. data (CART MCDA MCD MCD45A 16year year 16 20002015 2000 2015 (2000-2015 raster approach 1 databases physical aspects levels 3 units r 094 0 94 0.9 0.88 088 88 models model s making scale 2000201 200 201 (2000-201 09 9 0. 0.8 08 8 200020 20 (2000-20 20002 2 (2000-2 (2000- (2000 (200 (20 (2 (

There is a high demand for stroke rehabilitation in the Brazilian public health system, but most studies that have addressed rehabilitation for unilateral spatial neglect (USN) after stroke have been performed in high-income countries. Therefore, the aim of this study was to analyze USN patient recruitment in a multicenter noninvasive brain stimulation clinical trial performed in Brazil and to provide study design recommendations for future studies. We evaluated the reasons for exclusion of patients from a multicenter, randomized, double-blinded clinical trial of rehabilitation of USN patients after stroke. Clinical and demographic variables were compared between the included and excluded patients. A descriptive statistical analysis was performed. Only 173 of the 1953 potential neglect patients (8.8%) passed the initial screening. After screening evaluation, 87/173 patients (50.3%) were excluded for clinical reasons. Cognitive impairment led to the exclusion of 21/87 patients (24.1%). Low socioeconomic status led to the exclusion of 37/173 patients (21.4%). Difficulty obtaining transportation to access treatment was the most common reason for their exclusion (16/37 patients, 43.3%). The analyzed Brazilian institutions have potential for conducting studies of USN. The recruitment of stroke survivors with USN was restricted by the study design and limited financial support. A history of cognitive impairment, intracranial stenting or craniectomy, and lack of transportation were the most common barriers to participating in a multicenter noninvasive brain stimulation trial among patients with USN after stroke. system (USN highincome income countries Therefore randomized doubleblinded double blinded 17 195 8.8% 88 8 (8.8% evaluation 87173 87 87/17 50.3% 503 50 3 (50.3% 2187 21 21/8 24.1%. 241 24.1% . 24 1 (24.1%) 37173 37 37/17 21.4%. 214 21.4% 4 (21.4%) 16/37 1637 16 (16/3 43.3%. 433 43.3% 43 43.3%) support craniectomy 19 8.8 (8.8 8717 87/1 50.3 5 (50.3 218 2 21/ 24.1 (24.1% 3717 37/1 21.4 (21.4% 16/3 163 (16/ 43.3 8.

RESUMO O objetivo foi avaliar os efeitos de uma subdose de hCG aplicada no acuponto Hou Hai na qualidade do corpo lúteo (CL) e na indução da ovulação em éguas. Quinze éguas mestiças foram distribuídas em blocos ao acaso, sendo o período utilizado como fator de blocagem, em: T1 = 1500 UI de hCG por via intravenosa (IV); T2 = 450 UI de hCG aplicado no falso acuponto (IV) e T3 = 450 UI de hCG aplicada no acuponto Hou Hai. Avaliou-se diâmetro médio do CL, concentração sérica de progesterona (P4), vascularização do folículo pré-ovulatório e do CL. As fêmeas que receberam 450 UI de hCG no acuponto Hou Hai apresentaram maiores taxas de ovulação (33,33%) 48h após a indução. O número de pixels coloridos (NPC) mínimo do folículo pré-ovulatório das fêmeas do grupo controle foi superior (40,33) ao das éguas que receberam 450 UI de hCG IV no falso acuponto (36,84) e semelhante ao das éguas que receberam hCG no acuponto Hou Hai (39,31); correlações moderadamente positivas foram encontradas entre o diâmetro do CL e a concentração de P4, ambos no D8 (P <0,05). A administração IV de 450 UI de hCG ou no acuponto Hou Hai foi eficiente na indução da ovulação e na garantia da qualidade do CL nas éguas.
ABSTRACT The objective of this study was to evaluate the effects of an hCG sub dose applied at the Hou Hai acupoint on corpus luteum (CL) quality and ovulation induction in mares. Fifteen crossbred mares were distributed in randomized blocks and used in three periods with each period employed as the blocking factor in three treatments: T1 = 1500 IU of hCG via intravenous (IV); T2 = 450 IU of hCG applied at the false acupoint (IV); and T3 = 450 IU of hCG applied at the Hou Hai acupoint. Mean diameter of the CL, serum concentration of progesterone (P4), vascularization of the pre-ovulatory follicle and CL were evaluated. Females administered 450 IU of hCG at the Hou Hai acupoint exhibited greater ovulation rates (33.33%) 48h after induction; The minimum number of colored pixel (NCP) of the pre-ovulatory follicle of control females was superior (40.33) to that of mares administered 450 IU of hCG IV at the false acupoint (36.84) and similar to that of those administered hCG at the Hou Hai acupoint (39.31). Further, moderately positive correlations were found between the CL diameter and the P4 concentration on D8 (P<0.05). IV administration of 450 IU of hCG or at the Hou Hai acupoint was efficient at inducing ovulation and ensuring the quality of CL in mares.

RESUMO: A intoxicação por Prosopis juliflora (algaroba) cursa com sinais neurológicos, caquexia e morte, principalmente em bovinos e caprinos. Embora a disseminação descontrolada da algaroba na Caatinga (invasão biológica) tenha sido comprovada há cerca de 20 anos, o que altera as condições epidemiológicas dessa intoxicação, as estratégias de controle e profilaxia permanecem desatualizadas. Essas novas condições epidemiológicas permitem o consumo descontrolado de grande quantidade de vagens in natura de algaroba, por longos períodos, nas pastagens invadidas, o que tem resultado em aumento dos históricos de intoxicação. Objetivou-se com esse estudo descrever os novos aspectos epidemiológicos da intoxicação por P. juliflora em bovinos e caprinos, 78 anos após a introdução da planta no país, com ênfase no grau de invasão da planta, bem como atualizar as medidas de controle e profilaxia dessa intoxicação e das áreas de ocorrência dos surtos no semiárido baiano. Foram estudados in loco sete surtos (S1 a S7) de intoxicação natural por algaroba, sendo dois em caprinos (S1 e S2) e cinco em bovinos (S3, S4, S5, S6 e S7) no semiárido baiano (Juazeiro, Iaçu, Tucano, Santa Teresinha, Barra do Mendes, Barra e Tabocas do Brejo Velho). Nos surtos estudados, os achados clínico-epidemiológicos (S1 a S7) e histopatológicos (S1, S2, S3 e S5) foram compatíveis com intoxicação por algaroba, sendo essa intoxicação comprovada, pela primeira vez, com exames anatomopatológicos na Bahia. Ademais, na Bahia a doença ocorre em uma área cerca de três vezes maior do que a, até então, conhecida. Nas fazendas estudadas a introdução da algaroba ocorreu entre 1980 e 2005, através do plantio único de, em média, 33 mudas. Desde então, a disseminação da planta ocorreu de forma progressiva, invadindo gradativamente as pastagens nativas, o que permitiu avaliar a disseminação da planta (invasão biológica) nessas fazendas cerca de 15 (S2), 25 (S7), 30 (S5 e S6), 35 (S3) e 40 (S1 e S4) anos, após sua introdução. Informações históricas acerca da introdução da algaroba e sua disseminação na Bahia nunca haviam sido estudadas. Em 2020, verificou-se que nas pastagens das sete fazendas onde os surtos ocorreram, o grau de invasão por algaroba alcançou, em média, 59,57%. Chamou a atenção a grande capacidade de invasão biológica da planta, sobretudo, no S5. O alto grau de invasão da algaroba observado (novas condições epidemiológicas) justificou o aumento dos casos de intoxicação verificados nesse estudo. O beneficiamento das vagens (moagem) não era realizado em nenhuma fazenda (S1 a S7) e os ruminantes consumiam de forma descontrolada (livre) grande quantidade de vagens in natura, por longos períodos, nas pastagens invadidas, o que possibilitou a dispersão massiva das sementes da planta pelas fezes ao longo das décadas. O que aliado à inexistência de um plano de manejo do cultivo (tratamentos silviculturais) e ao desconhecimento da etiologia da doença pelos produtores foram os principais fatores responsáveis pela invasão gradativa da planta nas pastagens, ao longo dos anos, o que justifica o aumento dos casos de intoxicação observados na Bahia. Frente às novas condições epidemiológicas, a restrição do acesso dos animais as vagens in natura nas pastagens e o fornecimento do farelo de algaroba são cruciais para o controle e profilaxia dessa intoxicação, pois o consumo das vagens in natura teve forte correlação com o alto grau de invasão das pastagens onde os sete surtos ocorreram. Adicionalmente, embora a comercialização das vagens e a exploração da madeira da algaroba possam proporcionar renda extra aos pecuaristas e serem boas formas de manejo de áreas invadidas por algaroba, tais práticas ainda não são conhecidas ou não são realizadas de forma técnica ou a contento. A crescente invasão da algaroba no semiárido, 78 anos após a sua introdução no Nordeste, além de ser uma ameaça à biodiversidade da Caatinga é um risco para os rebanhos, visto que, a ocorrência de surtos de intoxicação podem se tornar mais frequentes. Desta maneira alerta-se para adoção de medidas efetivas de controle da propagação descontrolada da algaroba.
ABSTRACT: Poisoning by Prosopis juliflora (mesquite) leads to neurological signs, cachexia and death, mainly in cattle and goats. Although the uncontrolled spread of mesquite in the Caatinga biome (biological invasion), which alters the epidemiological conditions of intoxication by this plant, has been proved for approximately 20 years, strategies for its control and prophylaxis still remain out of date. These new epidemiological conditions have allowed the uncontrolled consumption of large amounts of in natura mesquite pods by ruminants for long periods in invaded pastures, thus resulting in increased history of poisoning. This study aimed to describe the new epidemiological aspects of P. juliflora poisoning in cattle and goats, 78 years after the introduction of this plant in the country, with emphasis on its degree of invasion, and to update the control and prophylaxis measures of this intoxication and the mapping of areas of outbreak occurrence in the semiarid region of the state of Bahia, Brazil. Seven outbreaks of natural mesquite poisoning, two in goats (OB 1 and OB 2) and five in cattle (OB 3, OB 4, OB 5, OB 6, and OB 7), were studied in loco in the municipalities of Juazeiro, Iaçu, Tucano, Santa Teresinha, Barra do Mendes, Barra and Tabocas do Brejo Velho. In the studied outbreaks, clinical-epidemiological (OB 1 to OB 7) and histopathological (OB 1, OB 2, OB 3, and OB 5) findings were compatible with mesquite poisoning, and this was the first anatomopathological proof of poisoning by this plant in this state. In addition, in the state of Bahia, disease occurs in an area approximately three times larger than previously known. On the farms investigated, mesquite introduction occurred between 1980 and 2005, through the single planting of an average of 33 seedlings. Since then, propagation of this plant has occurred progressively, with gradual invasion of native pastures, which enabled the evaluation of plant spread (biological invasion) on these farms 15 (OB 2), 25 (OB 7), 30 (OB 5 and OB 6), 35 (OB 3) and 40 (OB 1 and OB 4) years after its introduction. Historical information on the introduction and spread of mesquite in the state of Bahia had never been analyzed. In 2020, a degree of mesquite invasion an average 59.57% was verified in the pastures of the seven farms where the outbreaks occurred. The great biological invasion capacity of this plant drew attention, especially in OB 5. The high degree of mesquite invasion observed (new epidemiological conditions) justifies the increased number of cases of poisoning observed in this study. Processing of P. juliflora pods (grinding) was not carried out on any farm (OB 1 to OB 7), and ruminants uncontrollably consumed large amounts of pods in natura for long periods in invaded pastures, which allowed massive dispersal of seeds through feces over decades. The main factors responsible for the gradual invasion of pastures by mesquite over time were absence of crop management plans (silvicultural treatments) and lack of knowledge by producers on disease etiology. Given the new epidemiological conditions, restriction of animal access to in natura pods in pastures and supply of mesquite bran are crucial for the control and prophylaxis of this poisoning, as consumption of in natura pods had a strong correlation with the high degree of invasion in the pastures where the seven outbreaks occurred. Additionally, although the commercialization of pods and exploitation of wood of mesquite trees can provide livestock farmers with extra income - being the correct management for areas invaded by this plant, such practice is either not yet known or not carried out technically or satisfactorily by farmers. In addition to being a threat to the Caatinga’s biodiversity, the increasing invasion of semiarid areas by mesquite 78 years after its introduction in the Northeast region of Brazil, is a risk for herds, since the occurrence of poisoning outbreaks may become more frequent. Therefore, it is highly advisable that effective measures be adopted to control P. juliflora propagation.

Resumo O objetivo do presente trabalho foi avaliar as correlações entre produtividade e resposta à seca (RS) do eucalipto entre os atributos do solo em dois tipos climáticos distintos no Brasil. Para isto, foram instalados 24 experimentos no Brasil com 4 clones comuns em todos os experimentos para obter fortes contrastes edafoclimáticos, e, desse modo, mensurar a produtividade e a reposta à seca e descrever as suas relações com os atributos de solos. Foram avaliados dois grupos climáticos: Úmido (relação precipitação: evapotranspiração entre 1,0 a 2,5) e Subúmido (relação precipitação: evapotranspiração entre 0,5 a 1,0). Os atributos dos solos avaliados foram: Areia, Silte, Argila, matéria orgânica (M.O.), capacidade de troca catiônica (CTC). Para os sítios localizados na classe climática Úmida, o VCCC correlacionou-se negativamente com a M.O. e argila, e positivamente com a Areia. Para a RS, as correlações foram observadas para clima Subúmido para as variáveis CTC e Areia, e para o clima Úmido, não foram observadas correlações entre os atributos de solos com a RS.
Abstract The present study aimed to evaluate the correlations between productivity and eucalyptus drought response (DR) between soil attributes in two distinct climatic types in Brazil. For this, 24 experiments were installed in Brazil with four common clones in all the experiments to obtain strong edaphoclimatic contrasts, and, thus, to measure the productivity and the response to drought and to describe its relationship with the attributes of the soils. Two climatic groups were evaluated: Wet (precipitation rate: evapotranspiration between 1.0 to 2.5) and Sub-Humid (precipitation rate: evapotranspiration between 0.5 to 1.0). The attributes of the evaluated soils were: Sand, Silt, Clay, organic matter (O.M.), cation exchange capacity (CEC). For sites located in the wet climate class, CVWB correlated negatively with O.M. and clay, and positively with the sand. For DR, the correlations were observed for the Sub-Humid climate for the CEC and Sand variables, and for the Humid climate, no correlations were observed between the attributes of soils with DR.

RESUMO O uso de soluções eletrolíticas hipotônicas na hidratação enteral ainda é pouco estudado em bezerros. O objetivo do presente estudo foi avaliar os efeitos de soluções eletrolíticas enterais de manutenção com diferentes concentrações de acetato de sódio e diferentes osmolaridades em bezerros. Para isso, foram utilizados 18 bezerros, seis machos e 12 fêmeas, holandeses, com 20 dias de nascidos e pesando por volta dos 52kg. Os animais foram divididos aleatoriamente em três grupos e cada grupo recebeu um dos tratamentos. As três soluções eletrolíticas continham os mesmos componentes, mas em diferentes concentrações, resultando em uma solução hiposmótica, uma isosmótica e uma hiperosmótica. Cada animal foi mantido em hidratação enteral durante 12 horas com taxa de infusão de 15mL kg-1h-1. Foram aferidos perímetro abdominal, peso corporal, consistência das fezes, glicose e lactato plasmático, pH, pCO2, HCO- 3 e excesso de base nos seguintes tempos: T0h, T6h, T12h e T24h. A solução hiposmótica não gerou aparecimento de diarreia, enquanto a isosmótica e a hiperosmótica geraram. Independentemente da dose utilizada, o acetato não causou alcalose metabólica nos animais avaliados. Os resultados sugerem que o uso da solução hiposmótica em bezerros diarreicos, desidratados e sem acidose metabólica, pode ser clinicamente importante.
ABSTRACT The use of hypotonic electrolytic solutions in enteral fluid therapy is still understudied in calves. The objective of the present study was to evaluate the effects of maintenance enteral electrolytic solutions with different concentrations of sodium acetate and different osmolarities in calves. For this, 18 Holstein calves, six male and 12 female, 20 days old and weighing around 52kg, were used. The animals were randomly divided into three groups and each group received one of the treatments. The three electrolytic solutions contained the same components in different concentrations, resulting in a hyposmotic, an isosmotic and a hyperosmotic solution. Each animal was maintained in enteral fluid therapy for 12 hours with infusion rate of 15mL kg-1 h-1. Abdominal circumference, body weight, feces consistency, glucose and plasma lactate, pH, pCO2, HCO- 3 and BE were measured at the following times: T0h, T6h, T12h and T24h. The hyposmotic solution did not generate the onset of diarrhea, while the isosmotic and the hyperosmotic did. Regardless of the dose used, acetate did not cause metabolic alkalosis in the evaluated animals. The results suggest that the use of hyposmotic solution in diarrheic calves, dehydrated and without metabolic acidosis, may be clinically important.

RESUMO O presente estudo teve como objetivo avaliar os efeitos do período de transição em constituintes hematológicos e bioquímicos em éguas Mangalarga Marchador. Foram utilizadas 48 éguas para formar um grupo de manutenção (GM) e um grupo de transição (GT), composto por éguas gestantes e, após o parto, lactentes. Amostras de sangue foram coletadas nos seguintes tempos: T-60 (60 dias pré-parto), T-30 (30 dias pré-parto), T-15 (15 dias pré-parto), T0 (seis primeiras horas pós-parto), T15 (15 dias pós-parto), T30 (30 dias pós-parto) e T60 (60 dias pós-parto). O GT apresentou valores menores (P<0,05) de hemácias, hematócrito e hemoglobina, nos tempos T0, T15, T30 e T60, do que o GM. O volume corpuscular médio foi menor no GM (P<0,05) do que no GT (T0, T15, T30, T60) e a concentração corpórea de hemoglobina corpórea foi maior (P<0,05) no GM do que no GT (T15, T30, T60). Por outro lado, a distribuição do diâmetro dos eritrócitos apresentou um valor menor (P<0,05) no GM do que no GT (T15 e T30). Éguas em período de transição apresentam anemia regenerativa. Os resultados demonstram variações metabólicas de diferentes intensidades durante a gestação, o parto e o início de lactação.

Forty-eight mares were used to form a maintenance group (MG) and transition group (TG), formed by pregnant mares and, after delivery, infants. Blood samples were collected at the following times: T-60 (60 d pre-delivery), T-30 (30 d pre-delivery), T-15 (15 d pre-delivery), T0 (first 6h post-delivery), T15 (15 d post-delivery), T30 (30 d post-delivery), and T60 (60 d post-delivery). The TG had lower values (P< 0.05) of red blood cells, hematocrit and hemoglobin at T0, T15, T30 and T60 times than MG. The mean corpuscular volume was lower in MG (P< 0.05) than in TG (T0, T15, T30 and T60) and mean corpuscular hemoglobin concentration was higher (P< 0.05) in MG than in TG (T15, T30 and T60). On the other hand, the diameter distribution of red blood cells presented a lower value (P< 0.05) in MG than in TG (T15 and T30). Mares in transition period presented regenerative anemia. The results demonstrate physiological metabolic variations of different intensities during pregnancy, delivery and early lactation.

RESUMO O presente estudo avaliou e comparou os efeitos de soluções eletrolíticas enterais hipotônicas, administradas por sonda nasoesofágica em fluxo contínuo em cães submetidos a restrição hídrica, sobre o hematócrito, proteínas totais séricas, osmolaridade sérica, volemia, glicose e lactato plasmáticos, hemogasometria, ânion gap e DIF. Foram utilizados seis cães adultos (quatro machos e duas fêmeas). Todos os animais foram submetidos aos dois tratamentos propostos, em um delineamento crossover 6×2. Os tratamentos foram os seguintes: SEmalt - 5g de cloreto de sódio, 1g de cloreto de potássio, 1g de acetato de cálcio, 0,2g de pidolato de magnésio e 9,6g de maltodextrina, diluídos em 1.000mL de água (osmolaridade mensurada: 215mOsm L -1 ); SEdext - 5g de cloreto de sódio, 1g de cloreto de potássio, 1g de acetato de cálcio, 0,2g de pidolato de magnésio e 9,6g de dextrose, diluídos em 1.000mL de água (osmolaridade mensurada: 243mOsm L -1 ). Todas as soluções foram administradas no volume de 15mL kg -1 hora -1 , durante quatro horas, em fluxo contínuo. Ambas as soluções aumentaram o volume plasmático em cães desidratados, sem gerar o aparecimento de efeitos adversos. Porém, a SEmalt foi mais eficaz em promover a expansão da volemia.
ABSTRACT The present study assessed and compared the effects of hypotonic enteral electrolyte solutions administered by nasoesophageal tube in continuous flow in dogs submitted to water restriction on packed cell volume; total serum protein and serum osmolarity concentrations; blood volume; plasma glucose and lactate levels; blood gas analysis, anion gap, and strong ion difference. Six adult dogs were used (four males and two females). All animals were submitted to both proposed treatments in a crossover design 6×2. The treatments were as follows: ESmalt consisting of 5g sodium chloride, 1g potassium chloride, 1g calcium acetate, 0.2g magnesium pidolate, and 9.6g maltodextrin that were diluted in 1.000mL water (measured osmotic concentration of 215mOsm L−1) and ESdext consisting of 5g sodium chloride, 1g potassium chloride, 1g calcium acetate, 0.2g magnesium pidolate, and 9.6g dextrose that were diluted in 1.000mL water (measured osmotic concentration of 243mOsm L−1). All solutions were administered at 15ml kg−1 h−1 for 4 hours. Both solutions increased the plasma volume in dehydrated dogs without causing adverse effects. However, ESmalt was more effective in promoting the increase in blood volume.

RESUMO: A dessecação pré-colheita é uma estratégia importante no sentido de antecipar a colheita, evitando que a semente fique no campo em condições climáticas desfavoráveis. No entanto, pouco se sabe sobre o uso de dessecantes e as épocas de aplicação destes na cultura do feijão-caupi (Vigna unguiculata). Objetivou-se neste trabalho avaliar efeito da aplicação de dessecantes em diferentes épocas e de herbicidas dessecantes sobre a produtividade e a qualidade fisiológica de sementes de feijão-caupi. Foram avaliados cinco dessecantes: paraquat, aplicação sequencial de paraquat, amonio-glufosinate, glyphosate com aplicação sequencial de paraquat e mistura paraquat+diuron aplicados em quatro épocas: 50% das vagens com sementes formadas, com coloração verde (época I), 70% das vagens na coloração roxa (época II), 90% das vagens na coloração marrom (época III) e 100% das vagens na coloração marrom (época IV), mais uma testemunha sem a aplicação de dessecantes, em que a colheita foi realizada quando 100% de vagens estavam na coloração marrom. Avaliaram-se o número de dias de antecipação de colheita, produtividade, teste de uniformidade, massa de cem sementes, germinação e vigor das sementes. Nenhuma das estratégias de dessecação afetou a qualidade fisiológica das sementes, independentemente da época de aplicação. Os dessecantes paraquat, amonio-glufosinate e a mistura paraquat+diuron, quando aplicados nas épocas I e II, proporcionaram antecipação da colheita em até 13 dias e 9 dias, respectivamente, porém o tamanho das sementes e, consequentemente, a produtividade foram afetados.
ABSTRACT: Pre-harvest desiccation is an important strategy to anticipate harvesting, preventing the seed from being left in the field in unfavorable climatic conditions. However, little is known about the use of desiccants and their application times on cowpea (Vigna unguiculata). The objective of this study was to evaluate the effect of desiccant application at different seasons and of desiccant herbicides on productivity and physiological quality of cowpea seeds. Five dessicants were evaluated: paraquat, paraquat sequential application, glufosinate- ammonium, glyphosate with sequential application of paraquat and paraquat + diuron mixture applied in four seasons: 50% of the pods with green coloration and with seeds formed (season I); 70% of the pods in the purple coloration (season II), 90% of the pods in the coloration brown (season III) and 100% of the pods in the coloration brown (season IV), plus a control without the application of desiccants, in which harvesting was performed when 100% of the pods were brown. The number of days of anticipation of harvest, productivity, uniformity test, mass of one hundred seeds, germination and vigor of the seeds were evaluated. None of desiccation strategies affect the physiological seed quality, independent of the application season. The desquaments paraquat, glufosinate-ammonium and the paraquat+diuron mixture, when applied in seasons I and II, provided anticipation of the harvest in up to 13 days and 9 days, respectively, however, the size of the seeds and consequently the productivity were affected.

Abstract The growth of the population of cattle egrets (Bubulcus ibis) in the archipelago of Fernando de Noronha constitutes a threat to public health and biological diversity because of their competition with and predation on native species and the possibility of transmission of pathogens to human beings, livestock and native wildlife. The aim here was to search for, isolate and identify serovars of Salmonella in clinically healthy local cattle egrets. Cloacal swabs were obtained from 456 clinically healthy cattle egrets of both sexes and a variety of ages. The swabs were divided into 51 pools. Six of these (11.7%) presented four serovars of Salmonella enterica subspecies enterica: Salmonella serovar Typhimurium; Salmonella serovar Newport; Salmonella serovar Duisburg; and Salmonella serovar Zega. One sample was identified as S. enterica subspecies enterica O16:y:-. Results in this study suggest that cattle egrets may be reservoirs of this agent on Fernando de Noronha and represent a risk to public health and biological diversity.

O conhecimento dos padrões espaciais de parâmetros químicos dos solos são informações de suma importância para agricultura de precisão. Objetivou-se com este trabalho definir zonas de manejo por meio de classes de atributos químicos e produtividade média de soja em um campo de alta produção. As produtividades da soja foram quantificadas por meio de plantas coletadas em 1m², e os atributos químicos por meio de cinco coletas simples por ponto na camada de 0,00-0,20m num grid de 88 pontos de 60mX60m em dois anos consecutivos, sendo a massa de grãos pesadas e extrapoladas para t ha-1 considerando umidade de 10 %. Os mapas de classes foram gerados pelo software GS+ versão 7.0 em intervalos da média +/- 1,5 vezes o desvio padrão. A área de cada classe de produtividade foi calculada com o auxílio do software Google Earth por meio de sobreposição dos mapas. A classe considerada alta para produtividade foi predominante na região noroeste do mapa apresentando 8,217 ha, 6,508 ha de alto teor de K, 4,769 ha de alto teor de CTC e 3,708 ha de alto teor de M.O. Mesmo não apresentado correlação significativa a produtividade e atributos químicos apresentaram maiores valores na região noroeste do mapa.
Knowledge of spatial patterns of soil chemical parameters is critical information for precision agriculture. The objective of this work was to define management zones by means of classes of chemical attributes and average yield of soybean in a field of high production. Soybean yields were quantified by means of plants collected in 1 m 2 and the chemical attributes by means of five single samples per point in the layer of 0.00-0.20 m in a grid of 88 points of 60mX60m in two consecutive years, mass of heavy grains and extrapolated for t ha-1 considering 10% humidity. The class maps were generated by GS + version 7.0 software in average intervals +/- 1.5 times the standard deviation. The area of each productivity class was calculated with the help of the Google Earth program through overlapping maps. The class considered high for productivity was predominant in the northwest region of the map presenting 8,217 ha, 6,508 ha of high K content, 4,769 ha of high CTC content and 3,708 ha of high M.O. Although no significant correlation was found, productivity and chemical attributes presented higher values in the northwest region of the map.
