Efeito da aplicação de adubo organomineral misto como bioestimulante na produtividade da soja

Embora a soja seja economicamente um dos principais produtos agrícolas no cenário nacional e mundial, ainda se busca aumentar sua produtividade. Assim, objetivou-se, com o presente trabalho, avaliar o efeito da aplicação do adubo organomineral misto (AOM), em diferentes doses e em dois estádios fenológicos, na produtividade da soja. O experimento foi conduzido na área experimental da Universidade Federal de Jataí, no estado de Goiás, e foi instalado sob Sistema de Plantio Direto (SPD). O delineamento experimental utilizado foi de blocos casualizados em esquema fatorial 4 x 2 + 1, composto por 4 doses do AOM, aplicadas em 2 estádios fenológicos e 1 testemunha adicional. Foram avaliadas as seguintes doses do AOM: 0,5 kg ha-1; 1 kg ha-1, 1,5 kg h-1 e 2 kg h-1, em dois estádios reprodutivos: R3 e R5, e a testemunha adicional (tratamento controle). O experimento foi composto por 3 blocos. Cada parcela foi constituída por área útil de 16,2 m². Os parâmetros agronômicos avaliados foram: altura de planta (m), altura de inserção de primeira vagem (m), número de vagens por planta, número de grãos por vagem, massa de mil grãos (g) e produtividade (kg ha-1). A aplicação do AOM, como bioestimulante na cultura da soja, proporcionou incremento na altura de inserção de primeira vagem e no número de vagens por planta; não proporcionou maior produtividade, no entanto, quando aplicada no estádio fenológico R5 foi observada maior produtividade em comparação com a aplicação em R3.Although soybean is economically one of the main agricultural products in the national and world scenario, it is still needed to increase its grain yield. Therefore, this study aimed to evaluate the effect of applying mixed organomineral fertilizer (OMF) at different doses and at two phenological stages on soybean yield. The experiment was conducted in the experimental area of the Federal University of Jataí, in the state of Goiás, and was installed under a no-till system (NTS). The experimental design used was randomized blocks arranged in a 4 x 2 + 1 factorial scheme, consisting of four doses of OMF, applied at two phenological stages and one additional control. The following OMF doses were evaluated: 0.5 kg ha-1, 1 kg ha-1, 1.5 kg ha-1, and 2 kg ha-1, at two reproductive stages: R3 and R5, and the additional control. The experiment consisted of three blocks. Each plot had a useful area of 16.2 m². The agronomic parameters assessed were plant height (m), first pod insertion height (m), number of pods per plant, number of grains per pod, 1000-grain mass (g), and grain yield (kg ha-1). The application of OMF as a biostimulant to soybean crops led to an increase in the first pod insertion height and the number of pods per plant; it did not lead to higher yields; however, when applied at phenological stage R5, higher yields were observed compared to application at R3

Respostas à seleção de características de desempenho em tilápia‑do‑nilo

The objective of this work was to estimate genetic parameters and direct and indirect responses to selection for performance traits in Nile tilapia (Oreochromis niloticus), as well as to evaluate the impact of selection on genetic gain. Information about Nile tilapia, under selection in a genetic improvement program, grown in a net‑tank system, from 2008 to 2010, was used. Heritability and genetic correlations for the traits daily weight gain, and, immediately after catching, weight, width, height, and trunk length were estimated, besides the genetic gains obtained by the estimation of genetic tendencies and of the responses to selection for these traits. Heritability estimates were around 30%. The estimates of genetic and rank correlations had high magnitude. The direct genetic gain for daily weight gain was 7.9, 5.18, and 9.43% in 2008, 2009, and 2010, respectively. The genetic gains obtained from the genetic tendencies were 6.36, 6.30, 1.62, 1.65, and 1.51%, respectively, for daily weight gain, and trunk weight, width, height, and length. The increased growth rate through selection positively impacts performance traits in Nile tilapia.O objetivo deste trabalho foi estimar parâmetros genéticos e respostas direta e indireta à seleção de características de desempenho em tilápia‑do‑nilo (Oreochromis niloticus), bem como avaliar o impacto da seleção sobre o ganho genético.

Prognostic value of stress hyperglycemia for in-hospital outcome in acute coronary artery disease

FUNDAMENTO: Na síndrome coronariana aguda (SCA), a hiperglicemia, à admissão hospitalar, está associada à presença de eventos adversos cardiovasculares em pacientes com ou sem diabetes. OBJETIVO: Avaliar o valor prognóstico da hiperglicemia de estresse na evolução intra-hospitalar de pacientes admitidos por SCA. MÉTODOS: Foram incluídos 152 pacientes admitidos, entre setembro de 2005 e fevereiro de 2010, em unidade de dor torácica de hospital terciário com diagnóstico de SCA, que apresentavam valor da glicemia laboratorial na admissão. O grupo I foi formado pelos pacientes com hiperglicemia de estresse, definida por glicemia na admissão > 126 mg/dL em não diabéticos e > 200 mg/dL nos diabéticos, e o grupo II pelos pacientes com níveis glicêmicos inferiores aos níveis estabelecidos. Analisou-se a associação da hiperglicemia e evolução intra-hospitalar. RESULTADOS: A hiperglicemia de estresse associou-se a complicações intra-hospitalares, aumento da idade e gênero feminino. Na análise multivariada, apenas gênero feminino (OR = 2,04; IC95% 1,03 - 4,06, p = 0,007) e complicações intra-hospitalares (OR = 3,65; IC95% 1,62 - 8,19, p = 0,002) se associaram de forma independente à hiperglicemia na admissão. CONCLUSÃO: A hiperglicemia de estresse é fator preditivo independente para complicações intra-hospitalares após SCA em pacientes diabéticos ou não. Os resultados alertam para a necessidade de avaliarmos a glicemia na admissão em todos os pacientes admitidos por SCA, incluindo os não diabéticos, com o intuito de identificarmos os indivíduos com maior risco de complicações. _________________________________________________________________________________________ ABSTRACT: BACKGROUND: In acute coronary syndrome (ACS), admission hyperglycemia is associated with adverse cardiovascular events in diabetic and nondiabetic patients. OBJECTIVE: To assess the prognostic value of stress hyperglycemia for the in-hospital outcome of patients admitted due to ACS. METHODS: This study included 152 patients admitted to the chest pain unit of a tertiary hospital diagnosed with ACS, who had admission blood glucose data, from September 2005 to February 2010. Group I comprised patients with stress hyperglycemia, defined as admission blood glucose concentration > 126 mg/dL for nondiabetic individuals and admission blood glucose concentration > 200 mg/dL for diabetic individuals. Group II was formed by patients with admission blood glucose concentration lower than those established. The association of hyperglycemia and in-hospital outcome was assessed. RESULTS: Stress hyperglycemia associated with in-hospital complications, age increase and female sex. On multivariate analysis, only female sex (OR = 2.04; 95% CI: 1.03 - 4.06; p = 0.007) and in-hospital complications (OR = 3.65; 95% CI: 1.62 - 8.19; p = 0.002) associated independently with admission hyperglycemia. CONCLUSIONS: Stress hyperglycemia is an independent predictive factor for in-hospital complications after ACS in diabetic and nondiabetic patients. The results highlight the need to assess admission blood glucose concentration in all patients admitted due to ACS, including nondiabetic ones, aiming at identifying those at higher risk for complications

Magneto-structural versatility of copper(ii)-3-phenylpropionate coordination polymers with N-donor coligands

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)A novel series of copper(II) coordination polymers [Cu-2(O2CC8H9)(4)(pyz)](n) (1), [Cu-2(O2CC8H9)(4)(dps)](n) (2), {[Cu(O2CC8H9)(2)(dps)(H2O)]center dot H2O}(n) (3), {[NaCu(O2CC8H9)(2)(bpm)(NO3)]center dot H2O}(n) (4), and [Cu-4(O2CC8H9)(6)-(OH)(2)(bpp)(2)](n) (5) [O2CC8H9- = 3-phenylpropionate anion, pyz = pyrazine, dps = di(4-pyridyl)sulfide, bpm = 2,2'-bipyrimidine, and bpp = 1,3-bis(4-pyridyl)propane] have been synthesized and magneto-structurally investigated. Compounds 1 and 2 belong to a large group of copper(II) carboxylates where bis-monodentate pyz (1) and dps (2) ligands connect the paddle-wheel [Cu-2(II)(mu-O2CC8H9)(4)] units leading to alternating copper(II) chains. The structure of 3 consists of uniform chains of trans-[Cu-II(O2CC8H9)(2)] units linked by the bis-monodentate dps ligand. Compound 4 consists of heterobimetallic chains where [(Na2Cu2II)-Cu-I(mu-O2CC8H9)(4)(NO3)(2)] units are doubly bridged by bis-bidentate bpm ligands. Compound 5 is also a chain compound whose structure is made up by tetranuclear [Cu-4(II)(mu(3)-OH)(2)(mu-O2CC8H9)(4)(O2CC8H9)(2)] units which are doubly bridged by bis-monodentate bpp ligands. The magnetic properties were investigated in the temperature range 1.8-300 K. Strong antiferromagnetic interactions across the quadruple syn-syn carboxylate are observed in 1 and 2 [J = -378 (1) and -348 cm(-1) (2)] whereas a weak ferromagnetic coupling through the double out-of-plane oxo(carboxylate) bridge occurs in 4 [J = +2.66 cm(-1)], the spin Hamiltonian being defined as H = -JS(1).S-2 with S-1 = S-2 = S-Cu = 1/2. A quasi Curie law is observed for 3 (theta = -0.36 cm(-1)), the bis-monodentate dps ligand being a very poor mediator of magnetic interactions. The analysis of the magnetic properties of 5 is quite complex because of the presence of two crystallographically independent tetracopper(II) units with single-mu-hydroxo, di-mu-hydroxo, mu(3)-hydroxo and single-mu-hydroxo plus double syn, syn carboxylate bridges in each one. The nature and values of the magnetic couplings for 5 obtained by fitting (intermediate, strong and weak antiferromagnetic interactions for the three former exchange pathways respectively, and intermediate ferromagnetic interactions for the latter one) were substantiated by DFT type calculations.A novel series of copper(II) coordination polymers [Cu2(O2CC8H9)4(pyz)]n (1), [Cu2(O2CC8H9)4(dps)]n (2), {[Cu(O2CC8H9)2(dps)(H2O)]·H2O}n (3), {[NaCu(O2CC8H9)2(bpm)(NO3)]·H2O}n (4), and [Cu4(O2CC8H9)6(OH)2(bpp)2]n (5) [O2CC8H9− = 3-phenylpropionate anion,451172189CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE MINAS GERAIS - FAPEMIGCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)sem informaçãosem informaçãosem informaçãoThe authors thank the Conselho Nacional de Desenvolvimento Cientifico e Tecnológico (CNPq), the Fundação de Amparo à Pesquisa do Estado de Minas Gerais (FAPEMIG), the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), FINEP (ref. 134/08

Retrospective and Comparative Study of Giardia sp. Prevalence in Dogs, Cats, and Small Ruminants in Endemic Areas in Different Brazilian States

Background: Giardia, an intestinal parasite of asexual reproduction, is an important etiologic agent of diarrhea in animals and humans, transmitted by orofecal route. The disease caused by this agent, giardiasis, is endemic in the world and representing an important public health problem. The aim of the present study was do a retrospective study to determine the prevalence of Giardia sp. in fecal samples from dogs, cats, sheep and goats (small ruminants) evaluated at FMVZ Unesp, Botucatu, SP.  In addition, this study presents a review of the literature on the prevalence of this protozoan in dogs, cats and small ruminants in different states of Brazil, according to the environmental of these animals.Materials, Methods & Results: During 2011 to 2017, 2,698 fecal samples of dogs, 359 fecal samples of cats and 320 fecal samples of goats and sheep were analyzed. A total of 18.9% of the dogs, 24.8% of the cats, and 6.6% of the goats and sheep were positive for Giardia sp. Only previous studies that used the zinc sulphate centrifugal flotation (Faust technique) were included for comparation of prevalence. The prevalence of Giardia sp. in samples of centrifugation-fluctuation in zinc sulfate was similar in dogs, higher in cats and lower for small ruminants when compared to previous investigations. 4.4% and 6.7% of the positive samples from dogs and cats, respectively, were associated with some co-infection. Co-infections by Cystoisospora spp., Ancylostoma spp. and/ or Toxocara spp. were the most common for dogs and cats.Discussion: This study reveals the presence of Giardia sp. in different animal species in an endemic área. The results are similar to the prevalence previous reported in dogs, and higher in cats using the same diagnostic technique (Faust technique). Co-infections by Cystoisospora spp., Ancylostoma spp. and/ or Toxocara spp. were the most common for dogs and cats, as well-known in previous studies. Investigations with household, shelter and stray dogs found a significantly lower occurrence of Giardia sp. in the group of household dogs. However, for cats these comparisons should made with caution. Despite having a owner, some of these cats have free access to the streets, so they might be more expose to the sources of infection. There are few previous reports of the presence of Giardia sp. in goats and sheep, which presented much higher prevalence when compared with this study. This variation in prevalance of Giardia sp. in small ruminants can occur due to differences inherent to each region in Brazil, as well as the presence of risck factors regarding animal age, type of raising of the animals, hygienic-sanitary and management conditions, and the presence of domestic animals inside sheep and goat installations, which can potentially favor the mechanical transmission of cysts our reservoirs of this parasite. Therefore, due to regional variations in this parasite prevalence, this information is more value in regional areas, reaffirming the importance of this kind of studies in brazilian states and cities. The intermittent elimination of cysts in feces, the low number of cysts in the samples and asymptomatic infections are relevant points to the diagnosis of giardiasis, making it a challenge. The technique of centrifugation-flotation technique in zinc sulfate gives the best results when compared to other techniques available for the diagnosis of Giardia infections, justifying the choice of this technique by this study. These evidences associated to molecular diagnoses are necessary to determine the real role of these animals in the epidemiology and zoonotic transmission, due to the close contact with humans. This may be considering as a start for further investigations of Giardia sp. at municipality of Botucatu

EFFECT OF APPLYING MIXED ORGANOMINERAL FERTILIZER AS A BIOSTIMULANT ON SOYBEAN YIELD

Although soybean is economically one of the main agricultural products in the national and world scenario, it is still needed to increase its grain yield. Therefore, this study aimed to evaluate the effect of applying mixed organomineral fertilizer (OMF) at different doses and at two phenological stages on soybean yield. The experiment was conducted in the experimental area of the Federal University of Jataí, in the state of Goiás, and was installed under a no-till system (NTS). The experimental design used was randomized blocks arranged in a 4 x 2 + 1 factorial scheme, consisting of four doses of OMF, applied at two phenological stages and one additional control. The following OMF doses were evaluated: 0.5 kg ha-1, 1 kg ha-1, 1.5 kg ha-1, and 2 kg ha-1, at two reproductive stages: R3 and R5, and the additional control. The experiment consisted of three blocks. Each plot had a useful area of 16.2 m². The agronomic parameters assessed were plant height (m), first pod insertion height (m), number of pods per plant, number of grains per pod, 1000-grain mass (g), and grain yield (kg ha-1). The application of OMF as a biostimulant to soybean crops led to an increase in the first pod insertion height and the number of pods per plant; it did not lead to higher yields; however, when applied at phenological stage R5, higher yields were observed compared to application at R3
