Abstract The aim of this study was to evaluate the association between diabetes and cognitive performance in a nationally representative study in Brazil. We also aimed to investigate the interaction between frailty and diabetes on cognitive performance. A cross-sectional analysis of the Brazilian Longitudinal Study of Aging (ELSI-Brazil) baseline data that included adults aged 50 years and older was conducted. Linear regression models were used to study the association between diabetes and cognitive performance. A total of 8,149 participants were included, and a subgroup analysis was performed in 1,768 with hemoglobin A1c data. Diabetes and hemoglobin A1c levels were not associated with cognitive performance. Interaction of hemoglobin A1c levels with frailty status was found on global cognitive z-score (P-value for interaction=0.038). These results suggested an association between higher hemoglobin A1c levels and lower cognitive performance only in non-frail participants. Additionally, undiagnosed diabetes with higher hemoglobin A1c levels was associated with both poor global cognitive (β=-0.36; 95%CI: -0.62; -0.10, P=0.008) and semantic verbal fluency performance (β=-0.47; 95%CI: -0.73; -0.21, P=0.001). In conclusion, higher hemoglobin A1c levels were associated with lower cognitive performance among non-frail participants. Higher hemoglobin A1c levels without a previous diagnosis of diabetes were also related to poor cognitive performance. Future longitudinal analyses of the ELSI-Brazil study will provide further information on the role of frailty in the association of diabetes and glycemic control with cognitive decline.

RESUMO O objetivo deste estudo foi avaliar o efeito de diferentes níveis de ácidos graxos poli-insaturados ômega-3 (PUFA n-3) na dieta de Sardinella brasiliensis sobre seus parâmetros hematológicos. Um total de 375 peixes foi distribuído em 15 unidades experimentais para avaliar os efeitos da dieta em seu sangue durante 45 dias. Os níveis de PUFA n-3 adicionados à dieta foram 0, 0,3, 0,6, 0,9 e 1,2% da fração lipídica. Esses valores representam a porcentagem total de PUFA n-3 na fração lipídica da dieta, e 0% de PUFA n-3 foi usado como controle negativo. Cinco peixes de cada unidade experimental foram amostrados no final do experimento para análise hematológica, e os parâmetros medidos incluem o número total de eritrócitos, a porcentagem de hematócrito, a concentração de hemoglobina e glicose e a contagem diferencial de leucócitos. Foram observados números mais altos de eosinófilos circulantes em peixes alimentados com 0,3% e 1,2% de PUFA n-3. Embora não tenham sido observadas diferenças significativas em vários dos parâmetros, os resultados demonstram que a saúde das sardinhas não foi afetada pela adição de PUFA n-3 em sua dieta. Deve ser enfatizado que este é o primeiro estudo realizado com ênfase na análise sanguínea de S. brasiliensis. poliinsaturados poli insaturados ômega3 ômega 3 ômega- n3 n hematológicos 37 1 4 dias n- 0 03 0,3 06 6 0,6 09 9 12 2 1,2 negativo hematológica eritrócitos hematócrito leucócitos n3. 3.

ABSTRACT This study aimed to evaluate the effect of different levels of omega-3 polyunsaturated fatty acids (n-3 PUFA) in the diet of Sardinella brasiliensis on their hematological parameters. A total of 375 fish were distributed in 15 experimental units to evaluate the effects of the diet on their blood for 45 days. The levels of n-3 PUFA added in the diet were 0, 0.3, 0.6, 0.9, and 1.2% of the lipid fraction. These values represent the total percentage of n-3 PUFA in the lipid fraction of the diet, and 0% n-3 PUFA was used as the negative control. Five fish from each experimental unit were sampled at the end of the experiment for hematological analysis, and the parameters measured include the total number of erythrocytes, hematocrit percentage, hemoglobin and glucose concentration and differential leukocyte count. Higher numbers of circulating eosinophils were observed in fish fed 0.3% and 1.2% n-3 PUFA. Although no significant differences were observed in several of the parameters, the results demonstrate that the health of the sardines was not affected by the addition of n-3 PUFA in their diet. It should be emphasized that this is the first study with emphasis on the blood analysis of S. brasiliensis. omega3 omega 3 omega- n3 n (n- 37 1 4 days n- 0 03 0.3 06 6 0.6 09 9 0.9 12 2 1.2 control erythrocytes count S (n 0. 1.

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.

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.

Abstract Animals corpses in teaching and research institutions could be sources of infection for students and teachers when applied for dissection and surgical practice. This research aimed to evaluate cats’ corpses’ conservation using a new anatomic technique and vacuum package for seven days, aiming surgical practicing. A 150 mL/kg of alcohol with 5% glycerin and 120 mL/kg of a 20% sodium chloride, 1% nitrite, and 1% sodium nitrate solution was injected on corpses sealed in vacuum packages and put on 0 to 4°C. Skin and jejunum were collected on day 0 (fresh samples/control), and traction analysis was performed for seven consecutive days. On the last day, the liquid in the plastic bags was microbiologically analyzed. There was no statistical difference between control and conservation moments (D1 and D2) in maximal rupture force of the skin, and jejunum was similar to control in D2, D4, and D6. The microbial population did not exceed 6.0x104CFU/mL in total aerobics and 4.8x104CFU/mL in total anaerobes. Biomechanics was not significantly affected, and the microbiological count was low during conservation, demonstrating the possible effectiveness of this anatomical technique for surgery training.

Abstract A thermal comfort index for the Northeast of Brazil was analyzed for two scenarios of climatic changes, A1B and A2, for 2021-2080, and compared with the reference period 1961-1990. A technique of regionalization was applied to rainfall, maximum and minimum temperature data from meteorological stations, obtained by statistical downscaling of projections from four global climate models. The results pointed to a significant reduction of rainfall and an increase of temperature for three different climatically homogeneous subregions. Regarding the thermal comfort index, the results point to an increase in days with heat discomfort between 2021 and 2080. In the northern portion, the higher percentage of days with heat discomfort will be significant since the first half of the period under appreciation, i.e., from 2021 to 2050. Conversely, in the eastern of northeastern Brazil, the increase of days with heat discomfort should happen in the period from 2051 to 2080, whereas the central-western part of the region, which, in the reference period, had recorded less than 1% of days with heat discomfort, might see an elevation of that percentage to 7% between 2021 and 2050, potentially reaching 48% of its days made uncomfortable by heat between 2051 and 2080.

RESUMO Objetivou-se avaliar a condição metabólica e estrutural das células espermáticas bovinas após congelação, com adição prévia de IGF-I e insulina no meio diluidor seminal. Os ejaculados de seis touros Nelore foram submetidos a quatro tratamentos: controle; insulina (100µUI/mL); IGF-I (150ng/mL) e insulina + IGF-I (50µUI/mL e 75ng/mL, respectivamente). Após a congelação, realizaram-se os testes de termorresistência rápida, coloração pelo corante azul de tripan e Giemsa, além da análise computadorizada da motilidade espermática, da integridade das membranas plasmática e acrossomal, e da peça intermediária por meio de sondas fluorescentes. O teste de termorresistência rápida apresentou efeito dentro do tempo de cada tratamento, mas não entre os tratamentos. Na análise computadorizada da motilidade espermática, foram observados movimento, motilidade e velocidade espermáticos; não houve efeitos dos tratamentos sobre qualquer uma dessas variáveis. Respostas iguais foram obtidas com as sondas fluorescentes e o corante azul de tripan/Giemsa. A adição de insulina e IGF-I, de forma isolada ou combinada, ao meio diluidor para congelação de sêmen não produziu efeitos sobre as condições metabólica e estrutural das células espermáticas.
ABSTRACT This study aimed to evaluate the metabolic and structural condition of the spermatic bovine cells after the freezing, with addition, previously, of IGF-I and Insulin in the seminal thinner medium. The semen of 6 Nellore bulls were submitted to four treatments: Control, Insulin (100µUI/mL); IGF-I (150ng/mL) and Insulin + IGF-I (50µUI/mL and 75ng/mL, respectively). After freezing, rapid resistance tests, Tripan and Giemsa Blue staining, and computerized analysis of sperm motility and integrity of the plasma and acrosomal membranes and the intermediate part were performed by fluorescent probes. The term rapid resistance test had effect within the time of each treatment, but not between treatments. In the computer analysis of sperm motility, sperm movement, motility and velocity no effects of treatments were observed on any of these variables. The same results were obtained with the fluorescent probes and the Blue dye Trypan / Giemsa. The addition of Insulin and IGF-I, alone or in combination, to the semen freezing dilution medium had no effect on the metabolic and structural condition of sperm cells.

RESUMO Objetivou-se avaliar a viabilidade econômica de vacas F1 de Holandês x Zebu de diferentes bases maternas e ordens de parto. Foram utilizados dados do Campo Experimental da Epamig (Felixlândia-MG). Analisaram-se 406 lactações de vacas F1 H x Z de diferentes bases maternas. Estimaram-se a receita e os custos operacional efetivo, operacional total e custo total. As F1 Holandês x Gir tiveram médias de custos maiores (R$ 3582,30), seguidas pelas F1 Holandês x Nelogir (R$ 3448,06), e o menor foi das F1 Holandês x Nelore (R$ 3145,07). A receita total foi maior para as vacas F1 Holandês x Gir e F1 Holandês x Nelogir, com valores de R$ 4394,96 e R$ 4245,61, respectivamente, e a menor receita foi para F1 Holandês x Nelore, com valor de R$ 3976,12. O lucro foi de R$ 812, 65; R$ 797,54 e R$ 831,04 para as F1 filhas de base materna Gir, Nelogir e Nelore, respectivamente. Todas as bases maternas são viáveis economicamente e podem ser utilizadas no sistema de produção de leite e bezerros para venda. Todas as ordens de parto de Holandês x Zebu estudadas são viáveis economicamente.
ABSTRACT The objective was to evaluate the economic viability of a milk production system of F1 Holstein x Zebu cows of different maternal bases and calving order. Lactations data of F1 Holtein x Zebu cows (n=406) of different maternal bases, from the experimental field of the EPAMIG at Felixlândia county (MG state, Brasil) were analyzed. Revenue, cost/effect of operation, total operating, and total cost have been estimated. F1 cows Holstein x Gir had averages of higher costs R$ 3582.30, followed by F1 cows Holstein x Nelogir R$ 3448.06; and the lowest was from cows F1 Holstein x Nellore with R$ 3145.07. The total revenue was higher for Holstein x Gir and Holstein x Nelogir with recipe values of R$ 4394.96 and R$ 4245.61 respectively, and the lowest value of R$ 3976.12 for Holstein x Nellore. The profits were R$812.65; R$ 797.54 and R$ 831.04 for animals of groups Holstein x Gir, Holstein x Nelogir and Holstein x Nellore respectively. All genetic groups are economically viable and can be used in the production of milk and calves for sale. All calving order of Holstein x Zebu studied are viable economically.

RESUMO O objetivo desta pesquisa foi avaliar a influência do grupo genético do bezerro no comportamento alimentar diurno de mães e suas crias. Foram utilizadas 24 vacas Nelores paridas e seus bezerros, oito Nelores (puros), oito 1/2 Simental 1/2 Nelore e oito 1/2 Red Angus 1/2 Nelore. Avaliaram-se as medidas de frequência e duração das mamadas, tempo de pastejo e ruminação dos bezerros e das vacas. Os bezerros puros mamaram mais frequentemente que os mestiços (3,51 vs. 3,17 vezes/dia), porém com menor duração de mamada (7,37 vs. 7,80 minutos). A frequência de mamadas, a duração de cada mamada e o tempo total de mamadas diminuíram com o aumento da idade do bezerro. Nos bezerros, pastejo e ruminação aumentaram com a idade; entretanto, nas vacas, aumentou o tempo de pastejo e diminuiu o de ruminação com o passar dos dias. Os bezerros mestiços pastaram, em média, 18 minutos a mais que os puros, e os machos 16 minutos a mais que as fêmeas. Os bezerros machos ruminaram, aos 40 dias de idade, 25 minutos a mais que as fêmeas, mas essa diferença diminuiu com a idade e desapareceu por volta dos 220 dias. O comportamento da mãe e de sua cria é influenciado pelo grupo genético desta última.
ABSTRACT The aim of this study was to evaluate the effect of a calf's genetic group on the behavior of dam and calf. We used 24 Nellore dams and their calves, of which eight were Nellore, eight were 1/2Simmental 1/2Nelore and eight 1/2Red Angus 1/2Nellore. Grazing and rumination times, as well as suckling frequency and time, were measured. The straight bred calves suckled more often than the crossbreds (3.51 vs. 3.17 times/day), but their suckling lasted less time (7.37 vs 7.80 minutes). Suckling frequency, suckling length and total time spent suckling decreased as calf age increased. Calf grazing and rumination time increased with age; however, the cows' grazing time increased and rumination time decreased as the days postpartum went by. The crossbred calves grazed, on average, 18 minutes longer than the crossbreds, and the males grazed 16 minutes longer than the females. The male calves grazed, at 40 days of age, 25 minutes longer than the females, but this difference decreased as they grew and disappeared around 220 days. In conclusion, dam and calf behavior are influenced by the calf's genetic group.

Objetivou-se avaliar o efeito da ingestão de gossipol livre sobre a qualidade espermática e a morfologia dos testículos e dos epidídimos de touros da raça Nelore. Doze touros receberam dieta contendo 3,3g de gossipol livre/touro/dia (caroço de algodão) (Grupo 1, n=6) e dieta isenta de gossipol (Grupo 2, n=6), respectivamente. Foram realizadas coletas de sêmen no início e no final do experimento, que teve duração de 73 dias. Ao final do estudo, foram retirados os testículos e os epidídimos dos touros para se estudar o efeito do gossipol livre sobre as características histológicas. O consumo médio de 3,3g de gossipol livre/touro/dia (média 7,1mg de gossipol livre/kg/dia) reduziu a motilidade e a concentração espermática e aumentou a porcentagem de defeitos espermáticos maiores e totais. Além disso, os animais apresentaram testículos com túbulos seminíferos de menor espessura de parede, menor número de camadas de células espermatogênicas, menor espessura do epitélio epididimário e menor número de espermatozoide no interior dos ductos epidídimários, em relação aos animais com dieta isenta de gossipol (Grupo 2). O consumo de 3,3g de gossipol livre/touro/dia acarretou alterações na morfologia e na morfometria dos testículos e dos epidídimos e reduziu a qualidade espermática dos touros.
The objective was to evaluate the effect of intake of free gossypol on sperm quality and morphology of the testicles and epididymis of Nelore bulls. Twelve bulls were fed diets containing 3.3g of free gossypol/bull/day (cottonseed) (Group 1, n = 6) and a diet free of gossypol (Group 2, n = 6), respectively. Semen samples were collected in the beginning and end of the experiment which lasted 73 days. In the end of the study the testes and epididymis of bulls were removed to study the effect of free gossypol on histological characteristics. The average consumption of 3.3g of free gossypol/bull/day (mean 7.1mg of free gossypol/kg/day) reduced motility and sperm concentration and increased the percentage of major and total sperm defects, as well as the animals showing testes with seminiferous tubules of smaller thickness, fewer layers of spermatogenic lineage cells, smaller epididymal epithelium thickness and smaller number of sperm within the epididymal ducts, compared to animals with a diet free of gossypol (Group 2). The consumption of 3.3g of free gossypol/bull/day led to changes in morphology and morphometry of the testes and epididymis and reduced sperm quality of bulls.

O objetivo do presente estudo é avaliar o papel das colinesterases como marcadores inflamatórios nas fases aguda e crônica da infecção por T. evansi em coelhos infectados experimentalmente. Foram utilizados 12 coelhos adultos, fêmeas, da raça Nova Zelândia, divididos em dois grupos: um grupo controle, com seis animais (coelhos 1-6), e um grupo infectado, com seis animais (coelhos 7-12). Os animais pertencentes ao grupo infectados receberam, pela via intraperitoneal, 0,5 mL de sangue de rato contendo 108 tripanossomas por animal. Amostras do sangue utilizado para avaliação das colinesterases foram coletadas nos dias 0, 2, 7, 12, 27, 42, 57, 87, 102 e 118 pós-inoculação (PI). Aumento (P<0,05) na atividade da butirilcolinesterase (BChE) e da acetilcolinesterase foi observado no sangue nos dias 7 e 27 (PI), respectivamente e não foram observadas diferenças na atividade da colinesterase em outros períodos. Nenhuma diferença significativa na atividade da AChE (P>0,05) foi observada nas estruturas encefálicas. O aumento de atividade da AChE e BChE provavelmente tenha finalidade pró-inflamatória, a fim de reduzir as concentrações de acetilcolina, neurotransmissor que apresenta propriedade anti-inflamatória. Portanto, as colinesterases podem ser marcadores inflamatórios na infecção por T. evansi em coelhos.
The aim of this study is to evaluate the role of cholinesterases as an inflammatory marker in acute and chronic infection by Trypanosoma evansi in rabbits experimentally infected. Twelve adult female New Zealand rabbits were used and divided into two groups with 6 animals each: control group (rabbits 1-6) and infected group (rabbits 7-12). Infected group received intraperitoneally 0.5 mL of blood from a rat containing 108 parasites per animal. Blood samples used for cholinesterases evaluation were collected on days 0, 2, 7, 12, 27, 42, 57, 87, 102 and 118 days post-inoculation (PI). Increased activity (P<0.05) of butyrylcholinesterase (BChE) and acetylcholinesterase (AChE) were observed in the blood on days 7 and 27, respectively and no differences were observed in cholinesterase activity in other periods. No significant difference in AChE activity (P>0.05) was observed in the encephalic structures. The increased activities of AChE and BChE probably have a pro-inflammatory purpose, attempting to reduce the concentration of acetylcholine, a neurotransmitter which has an anti-inflammatory property. Therefore, cholinesterase may be inflammatory markers in infection with T. evansi in rabbits.

Cinquenta e sete subprodutos foram coletados de diferentes regiões do Brasil. Foram determinados a composição química, a digestibilidade in vitro da fibra em detergente neutro (DIVFDN) e os nutrientes digestíveis totais (NDT), com o objetivo de agrupar os subprodutos com características nutricionais semelhantes. Os subprodutos pertencentes a um grupo (G1) apresentaram maior conteúdo de fibra em detergente neutro corrida para cinzas e compostos nitrogenados (FDNcp) e menor teor energético, e tinham 42,5% e 38,8% de DIVFDN e NDT, respectivamente. Uma nova análise de cluster foi realizada no intuito de melhor caracterizar os subprodutos do G2; seis subgrupos (SG) foram estabelecidos (SG1 a SG6). Os subprodutos SG1 tiveram os maiores e os menores valores de lignina e NDT, respectivamente. Os subprodutos SG2 tiveram o maior valor de FDNcp, com valores de NDT e DIVFDN acima de 600 e 700g/kg, respectivamente, e de proteína bruta (PB) abaixo de 200g/kg de matéria seca (MS). Entre todos os subgrupos, SG3 tiveram os maiores valores de NDT (772g/kg) e DIVFDN (934g/kg) e o menor valor de lignina (23g/kg de MS). O extrato etéreo foi o que mais influenciou no estabelecimento hierárquico de agrupamento em SG4. Os subprodutos SG5 tinham maior concentração de carboidratos não fibriosos. Diferentemente dos demais subgrupos, subprodutos SG6 tinham o valor mais elevado de PB disponível.
Fifty-seven by-products were collected from regions throughout Brazil. Chemical composition, in vitro neutral detergent fiber digestibility (IVNDFD), and total digestible nutrients (TDN) were determined with the objective of grouping by-products with similar nutritional characteristics. The by-products belonging to group one (G1) presented the highest content of neutral detergent fiber exclusive of ash and nitrogenous compounds [aNDFom(n)] and lowest energy content, with 42.5% and 38.8% of IVNDFD and TDN, respectively. A new cluster analysis was carried in order to better characterize G2 by-products, six subgroups (SGs) were established (SG1 to SG6). SG1 by-products had the highest and the lowest values for lignin and TDN, respectively. SG2 by-products had the highest aNDFom(n) value, with TDN and IVNDFD values greater than 600 and 700g/kg, respectively, and crude protein (CP) value below 200g/kg in dry matter (DM). Among all the subgroups, SG3 had the highest TDN (772g/kg) and IVNDFD (934g/kg) values and the lowest lignin (23g/kg in DM) value. The ether extract was what most influenced the hierarchical establishment of residual grouping in SG4. SG5 by-products had the highest concentration of non-fibrous carbohydrate. Different from the other subgroups, SG6 by-products had the highest value of available CP.

Fusarium species have emerged as one of the more outstanding groups of clinically important filamentous fungi, causing localized and life-threatening invasive infections with high morbidity and mortality. The ability to produce different types of hydrolytic enzymes is thought to be an important virulence mechanism of fungal pathogens and could be associated with the environment of the microorganism. Here, we have measured the production of two distinct lipolytic enzymes, phospholipase and esterase, by sixteen Fusarium isolates recovered from the hospital environment, immunocompromised patients’ blood cultures, foot interdigital space scrapings from immunocompromised patients, and foot interdigital space scrapings from immunocompetent patients (4 isolates each). Fourteen of these 16 isolates were identified asFusarium solani species complex (FSSC) and two were identified as F. oxysporum species complex (FOSC). Some relevant genus characteristics were visualized by light and electron microscopy such as curved and multicelled macroconidia with 3 or 4 septa, microconidia, phialides, and abundant chlamydospores. All Fusarium isolates were able to produce esterase and phospholipase under the experimental conditions. However, a negative correlation was observed between these two enzymes, indicating that a Fusarium isolate with high phospholipase activity has low esterase activity and vice versa. In addition, Fusarium isolated from clinical material produced more phospholipases, while environmental strains produced more esterases. These observations may be correlated with the different types of substrates that these fungi need to degrade during their nutrition processes.

The aim of this research was to evaluate the economic viability of using male-sexed semen to Nellore bulls production. The experiment was conducted on two farms of breeders and selectors of Nellore bulls for sale. The females included 433 heifers (2 years old) and 230 non-suckling cows, totaling 663 animals. Average body condition score was 3.25±0.5 (1-5 scale). The total pregnancy rate of females inseminated with male-sexed semen of bulls A, B and C was 38.76% (131/338) lower (p<0.0001) than the total pregnancy rate observed for females inseminated with conventional semen from the same bulls (57.85% [188/ 325]). The use of male sexed semen showed a profit of US$ 1163.43, when compared with conventional semen to Nellore bulls production. It was concluded that the use of male sexed semen is economically viable for Nellore bulls production, but presents greater risks than the use of conventional semen for this purpose.
Objetivou-se com esta pesquisa avaliar a viabilidade econômica da utilização de sêmen sexado macho para produção de touros Nelore. O experimento foi realizado em duas propriedades de criadores e selecionadores de touros Nelore para comercialização. Foram inseminadas 663 fêmeas, sendo 433 novilhas de dois anos de idade e 230 vacas adultas sem bezerro ao pé. O escore corporal médio dos animais era de 3,25±0,5 numa escala de 1-5. A taxa total de gestação das fêmeas inseminadas com sêmen sexado macho dos touros A, B e C foi de 38,76% (131/338), valor inferior (p<0,001) à taxa total de gestação observada nas fêmeas inseminadas com sêmen convencional dos mesmos touros, que foi de 57,85% (188/325). O uso de sêmen sexado macho apresentou um lucro de 1163,43 dólares, em relação à utilização de sêmen convencional para produção de reprodutores Nelore. Concluiu-se que a utilização de sêmen sexado de macho é economicamente viável para produção de touros Nelore, entretanto apresenta maiores riscos que a utilização de sêmen convencional para esse propósito.

The objective of this experiment was to evaluate morphogenetic and structural characteristics and biomass production of buffel grass as a function of cut intensities and frequencies. A previously established pasture of buffel grass cultivar Molopo was used. Total area was splited in twenty 8 m² experimental unities with 1 m border lines. A split plot scheme was used with plot in factorial scheme 2x2 to combination of two height of cut (60 and 80 cm) and two height post cut (20 and 40 cm). The experimental design was entirely randomized blocks, with five replicates named 2060, 20-80, 40-60, 40-80. There (p<0.05) of treatments for dry matter per cut production and higher values were observed to 20-80 and 40-80. Tillering, leaf/steam ratio, number of alive leafs per tiller and diameter of plant were influenced by (p<0.05) by different management of buffel grass. Leaf appearance ratio and phylocron were not different (p>0.05) between treatments. Cutting frequency and intensities influenced tillering, leaf/ stem ratio and dry matter production for both the cut as to the total.
Objetivou-se avaliar características morfogênicas, estruturais e a produção de biomassa do capim-buffel sob intensidades e freqüências de corte. Utilizou-se um pasto já implantado de capimbuffel, cultivar Molopo. A área total utilizada foi dividida em 20 parcelas de 8 m² cada com linha de bordadura de 1 m entre as parcelas. Foi utilizado um esquema de parcelas subdivididas no tempo, tendo nas parcelas um arranjo fatorial 2x2 referente a combinações entre duas alturas de corte (60 e 80 cm) e duas alturas de resíduo (20 e 40 cm), em delineamento experimental de blocos completos ao acaso, com cinco repetições, totalizando 20 unidades experimentais, que receberam as denominações 20-60, 20-80, 40-60, 40-80. Houve efeito (p<0,05) dos tratamentos para a produção de matéria seca por corte, sendo que os tratamentos 20-80 e 40-80 resultaram em maiores produções. O perfilhamento, relação lâmina/colmo, número de folhas vivas por perfilho e diâmetro de touceira, foram influenciados (p<0,05) pelas diferentes formas de manejar o pasto de capimbuffel. A taxa de aparecimento de folhas e o filocrono não diferiram (p>0,05), entre os tratamentos. A freqüência e a intensidade de corte influenciaram o perfilhamento, relação lâmina/colmo e a produção de matéria seca do capim-buffel tanto para o corte como para a produção total.
