ABSTRACT

A utilização da gema de ovo dificulta a padronização de meios diluidores e apresenta riscos biológicos. Assim, este estudo avaliou diferentes concentrações da lipoproteína de baixa densidade (LDL), em substituição à gema de ovo, para a confecção de diluentes para criopreservação espermática em ovinos. Foram utilizados um diluidor controle (CTR= 20% de gema de ovo) e cinco tratamentos, substituindo-se a gema pelas diferentes proporções de LDL (T1=6%; T2=8%; T3=12%; T4=16%; T5=20%), todos à base de TRIS-glicerol. Para o estudo, utilizaram-se dois ejaculados, de seis reprodutores da raça Santa Inês. Sessenta dias após a criopreservação, as amostras foram descongeladas e avaliadas subjetivamente quanto à motilidade total (MT, %) e progressiva (MP, %), ao vigor (1-5) e à integridade funcional (choque hisposmótico com água destilada, %) e estrutural (corante supravital eosina, %) das membranas espermáticas. As avaliações de vigor e funcionalidade de membrana não diferiram (P>0,05) entre os grupos. Entretanto, os grupos T4 (P<0,01) e T5 (P<0,05) foram superiores ao CTR para os parâmetros MT, MP e integridade estrutural de membrana, o que confirma que as LDLs podem ser alternativas eficientes para substituição da gema de ovo em diluidores para criopreservação de sêmen ovino.(AU)


The use of egg yolk makes it difficult to standardize extenders and presents biological hazards. Thus, this study evaluated different concentrations of low-density lipoprotein (LDL) to replace yolk extenders for production of sperm for cryopreservation in ovine. A control extender was used (CTR= 20% yolk) and five treatments, replacing the yolk by different ratios of LDL (T1= 6%; T2= 8%, T3= 12%; T4= 16%; T5= 20%) all based on TRIS-glycerol. For the study, two ejaculates from six Santa Ines breeding were used. Sixty days after cryopreservation, the samples were thawed and evaluated for total motility (MT, %) and progressive motility (MP, %), vigor (1-5) and the functional integrity (hyposmotic shock with distilled water, %) and structural (supravital dye eosin, %) of the sperm membranes. The evaluations of strength and membrane functionality didn't differ (P> 0.05) between groups. However, T4 (P< 0.01) and T5 (P< 0.05) groups were superior to the CTR for the MT, MP, and membrane structural integrity parameters, which confirms that LDLs can be efficient alternatives for yolk replacement in extenders for cryopreservation of ovine semen.(AU)

ABSTRACT

O objetivo deste estudo foi avaliar o efeito da suplementação mineral injetável extra de cobre (Cu) e zinco (Zn) sobre a resposta imunológica de vacas Nelore no período pré-parto. Foram avaliadas 60 vacas prenhes, as quais foram divididas em dois tratamentos, por meio da distribuição aleatória em delineamento inteiramente ao acaso. Aos 75 dias antes do parto, as vacas do tratamento testemunha (T) receberam soro fisiológico como placebo e os animais suplementados (S) receberam mineral injetável via subcutânea (75mg de cobre e 250mg de zinco, em dose única). Foram realizadas três coletas de sangue, duas antes da data prevista para o parto (75 e 10 dias) e uma 30 dias após o parto. Os teores de Cu, Zn, ceruloplasmina, imunoglobulinas G (IgG) e M (IgM) foram analisados durante as três coletas. A atividade fagocitária foi avaliada aos 30 dias pós-parto. Os dados foram examinados mediante análise de variância, com o uso do pacote estatístico do SAS, e os dados individuais da atividade fagocitária pelo PROC GLM. Os dados de Cu, Zn, IgG e IgM foram analisados como medidas repetidas no tempo de coleta por meio do PROC MIXED, com o nível de significância de 5%. Os teores de Cu, Zn, IgM, IgG, ceruloplasmina e a atividade fagocitária das vacas não sofreram influência dos tratamentos (P>0,05). O fornecimento de Cu e Zn injetável, nas doses utilizadas, aos 75 dias antes do parto para vacas Nelore, em dietas suficientes, não alterou os teores de Cu, Zn, ceruloplasmina e a resposta imunológica até 30 dias após o parto.(AU)


The aim of this study was to evaluate the effect of extra injectable mineral supplementation of copper (Cu) and zinc (Zn) on the immune response of Nellore cows in pre-partum period. Sixty pregnant cows were randomly distributed in a completely randomized design in two treatments. In the control treatment (T), cows received saline as placebo, and supplemented treatment (S) received mineral injection (75mg copper and 250mg of zinc, single dose) subcutaneously, 75 days prior to parturition. Blood was sampled three times, two before the expected date of parturition (75 and 10 days) and another at 30 days postpartum. Analyses were performed for Cu, Zn, ceruloplasmin, immunoglobulin G (IgG) and M (IgM) in the three periods and the phagocytic activity in the last period (30 days postpartum). The experimental data were subjected to analysis of variance using the statistical package SAS, being that the individual data phagocytic activity were analyzed by PROC GLM, and the Cu, Zn, IgG and IgM were analyzed as repeated measures in the time, using the PROC MIXED, with the significance level of 5%. The Cu, Zn, IgM, IgG, ceruloplasmin and the phagocytic activity of the cows were not affected by treatments (P>0.05). The supply of injectable Cu and Zn, at the doses used, 75 days before parturition to Nellore cows in sufficient diets, did not alter the serum contents of Cu, Zn, ceruloplasmin and the immune response up to 30 days after parturition.(AU)

ABSTRACT

Abstract Population growth in urban areas changes freshwater ecosystems, and this can have consequences for macrophyte communities as can be seen in the municipalities that border the Capibaribe River, Pernambuco, Brazil. This study reports the effects of urbanization on the composition and structure of macrophyte communities in areas along that river. The following urbanized and non-urbanized sampling sites were chosen: Sites 1 and 2 (municipality of Santa Cruz do Capibaribe), Sites 3 and 4 (municipality of Toritama), and Sites 5 and 6 (metropolitan region of Recife). These sites were visited every two months from January to July 2013 to observe seasonal variation (wet and dry seasons). Thirty-one species were identified. Generally, the non-urbanized sites had a higher number of species. Multivariate analyses indicated significant overall differences between urbanized and non-urbanized areas (R = 0.044; p < 0.001) and between seasons (R = 0.018; p < 0.019). Owing to the large variation in physical, chemical, and biological characteristics between urbanized and non-urbanized areas, we found that urbanization significantly influenced the floristic composition and structure of macrophyte communities.


Resumo O crescimento populacional em áreas urbanas causa alterações em ecossistemas aquáticos continentais com consequência sobre as comunidades de macrófitas. Este fato vem ocorrendo nos municípios que margeiam o rio Capibaribe, Pernambuco, Brasil. Este trabalho analisa os efeitos da urbanização sobre a composição e estrutura das macrófitas em trechos do referido Rio. Levando em consideração áreas urbanizadas e não urbanizadas, foram escolhidos os seguintes Pontos de Coleta: Pontos 1 e 2 no Município de Santa Cruz do Capibaribe, Pontos 3 e 4 no Município de Toritama, Pontos 5 e 6 na Região Metropolitana do Recife. Estes pontos foram visitados bimestralmente (janeiro – julho/2013), para a observação da variação sazonal (estações seca e chuvosa). Foram identificadas 31 espécies. Geralmente, os pontos das áreas não urbanizadas apresentaram um número maior de espécies. As análises multivariadas indicaram diferenças globais significativas entre áreas urbanizadas e não urbanizadas (R = 0,044, p < 0,001) e também entre as estações (R = 0,018; p < 0,019). Devido à grande variação física, química e biológica entre as áreas urbanizadas e não urbanizadas, observou-se que o fator urbanização influenciou significativamente na composição florística e na estrutura das comunidades de macrófitas.

ABSTRACT

Plasma cortisol and glucose levels were measured in 36 adult Nile tilapia males, Oreochromis niloticus (standard length, mean ± SD, 14.38 ± 1.31 cm), subjected to electroshock and social stressors. Pre-stressor levels were determined 5 days after the adjustment of the fish to the experimental aquaria (1 fish/aquarium). Five days later, the effects of stressors on both cortisol and glucose levels were assessed. The following stressors were imposed for 60 min: pairing with a larger resident animal (social stressor), or a gentle electroshock (AC, 20 V, 15 mA, 100 Hz for 1 min every 4 min). Each stressor was tested in two independent groups, one in which stress was quantified immediately after the end of the 60-min stressor imposition (T60) and the other in which stress was quantified 30 min later (T90). Pre-stressor values for cortisol and glucose were not statistically different between groups. Plasma cortisol levels increased significantly and were of similar magnitude for both electroshock and the social stressor (mean ± SD for basal and final samples were: electroshock T60 = 65.47 ± 15.3, 177.0 ± 30.3; T90 = 54.8 ± 16.0, 196.2 ± 57.8; social stress T60 = 47.1 ± 9.0, 187.6 ± 61.7; T90 = 41.6 ± 8.1, 112.3 ± 26.8, respectively). Plasma glucose levels increased significantly for electroshock at both time points (T60 and T90), but only at T90 for the social stressor. Initial and final mean (± SD) values are: electroshock T60 = 52.5 ± 9.2, 115.0 ± 15.7; T90 = 35.5 ± 1.1, 146.3 ± 13.3; social stress T60 = 54.8 ± 8.8, 84.4 ± 15.0; T90 = 34.5 ± 5.6, 116.3 ± 13.6, respectively. Therefore, electroshock induced an increase in glucose more rapidly than did the social stressor. Furthermore, a significant positive correlation between cortisol and glucose was detected only at T90 for the social stressor. These results indicate that a fish species responds differently to different stressors, thus suggesting specificity of fish stress response to a stressor.

ABSTRACT

O presente estudo apresenta as concentrações de Hg em cinco espécies abundantes de macrófitas aquáticas (Elodea densa, Sagittaria montevidensis, Salvinia auriculata, Pistia stratiotes e Eichhornia crassipes) coletadas em duas represas que recebem águas da transposição do rio Paraíba do Sul, SE do Brasil. A acumulação de Hg nessas espécies e seu papel no transporte de Hg ao longo do sistema fluvial devido ao manejo das macrófitas são discutidos. As concentrações de Hg foram maiores nas macrófitas flutuantes que nas enraizadas. Em geral, as raízes apresentaram maiores concentrações de Hg que as folhas para todas as espécies. As concentrações de Hg variaram de acordo com as espécies entre 46-246 ng.g-1 e 37-314 ng.g-1, respectivamente. Estas concentrações são maiores que aquelas relatadas para macrófitas coletadas em lagos não contaminados no Brasil e em outras regiões tropicais, e similares àquelas relatadas para áreas moderadamente contaminadas. As concentrações de Hg podem ser atribuídas ao transporte fluvial a partir da região industrializada do vale do rio Paraíba do Sul. Uma amostragem intensiva de Pistia stratiotes na represa do Vigário foi realizada para avaliar a capacidade de incorporação de Hg por esta macrófita. Os resultados mostraram uma correlação negativa, significativa, entre as concentrações de Hg e o tamanho dos indivíduos, demonstrando a importância de juvenis desta espécie na absorção de Hg. A retirada periódica de macrófitas da represa, seguida por sua disposição em áreas adjacentes, pode afetar a dinâmica do Hg. Os resultados mostram uma mobilização de 0,52 a 1,3 kg Hg por ano, uma fração significativa da carga total de Hg presente nas águas da represa. A disposição inadequada deste material poderá resultar em um aumento da mobilização de Hg na bacia.

ABSTRACT

This paper reports on a study to determine the Hg content in the five most abundant aquatic macrophyte species (Elodea densa, Sagittaria montevidensis, Salvinia auriculata, Pistia stratiotes and Eichhornia crassipes) in two artificial reservoirs flooded by water diverted from the Paraíba do Sul river, SE Brazil. The potential of these species for Hg accumulation and their role in Hg transport along the river system due to macrophyte management were evaluated. Mercury concentrations were higher in free-floating than in rooted species. Roots were also richer in Hg than were leaves. Dry weight Hg concentrations in leaves and roots from all species varied from 46-246 ng.g-1 to 37-314 ng.g-1, respectively. These values are higher than those reported for uncontaminated lakes in Brazil and in other tropical areas and similar to those reported for moderately contaminated sites. Mercury concentrations can be attributed to fluvial transport from the heavily industrialized Paraíba do Sul river basin. Intensive sampling of Pistia stratiotes from two sites in the Vigário reservoir was performed to evaluate the capacity of Hg incorporation in short periods of time. The results showed a significant negative correlation between Hg content and size class of individual plants, demonstrating the importance of juveniles, fast growing plants in absorbing Hg. The foremost impact related to Hg contents in the studied area concerns the periodic removal of macrophytes for reservoir management, followed by disposal in nearby areas. This results in the mobilization of 0.52 to 1.3 Kg of Hg per year, a significant fraction of the Hg burden present in reservoir waters. Disposal of such material may result in Hg leaching to river systems, affecting the Hg transfer throughout the basin.

ABSTRACT

We investigated the association of eye color with the dominant-subordinate relationship in the fish Nile tilapia, Oreochromis niloticus. Eye color pattern was also examined in relation to the intensity of attacks. We paired 20 size-matched fish (intruder: 73.69 ± 11.49 g; resident: 75.42 ± 8.83 g) and evaluated eye color and fights. These fish were isolated in individual aquaria for 10 days and then their eye color was measured 5 min before pairing (basal values). Twenty minutes after pairing, eye color and fights were quantified for 10 min. Clear establishment of social hierarchy was observed in 7 of 10 pairs of fish. Number of attacks ranged from 1 to 168 among pairs. The quartile was calculated for these data and the pairs were then divided into two classes: low-attack (1 to 111 attacks - 2 lower quartiles) or high-attack (112 to 168 attacks - 2 higher quartiles). Dominance decreased the eye-darkening patterns of the fish after pairing, while subordinance increased darkening compared to dominance. Subordinate fish in low-attack confrontations presented a darker eye compared to dominant fish and to the basal condition. We also observed a paler eye pattern in dominants that shared low-attack interactions after pairing compared to the subordinates and within the group. However, we found no differences in the darkening pattern between dominants and subordinates from the high-attack groups. We conclude that eye color is associated with social rank in this species. Moreover, the association between eye color and social rank in the low-attack pairs may function to reduce aggression.

ABSTRACT

Female Nile tilapia incubate fertilized eggs in their mouth until they are released as alevins. Consequently, the female may not eat during this period. Thus, it would be expected that female Nile tilapia are more adapted to recovering from fasting than males, which do not display this behavior. To test this hypothesis we conducted an experiment with two groups of fish consisting of 7 males and 7 females each, with one fish per aquarium. The experiment was divided into three phases involving adjustment of the animals to experimental aquaria (0-15th day), fasting (16th-27th day), and refeeding (27th-42nd day). Compensatory growth performance was assessed by specific growth rate, weight, food conversion efficiency and food intake. Food conversion efficiency increased after fasting with a similar rate for both sexes. However, specific growth rate, food intake and weight gain ( percent) were significantly higher in males than in females in the refeeding phase. Thus, we conclude that male Nile tilapia can compensate for a fasting period more efficiently than females, refuting our hypothesis. A possible mechanism involved in the greater male compensation is that they presented greater hyperphagia than females, concomitantly with a similar rate of food conversion efficiency for both sexes during refeeding, which would probably be provoking greater growth in males

ABSTRACT

The present study aimed to test the effects of blue, green or white light on the stress response of the Nile tilapia, Oreochromis niloticus (L.). Each color was tested on two groups of isolated adult Nile tilapia (8 replicates each): one being subjected to confinement stress, and the other not (control). A different environmental color was imposed on each compartment by covering the light source with cellophane of the respective color (green or blue; no cellophane was used for white light). The intensity of green, white and blue lights was 250, 590 and 250 lux, respectively. Basal plasma cortisol levels were determined for each fish prior to the experimental procedures. The fish were confined by being displaced toward one side of the aquarium using an opaque partition for 1 h both in the morning and the afternoon of the two consecutive days of the test. At the end of this 48-h period, plasma cortisol levels were measured again. Basal cortisol levels (ng/ml) were similar for each group (ANOVA, F(2;42) = 0.77, P = 0.47). Thus, plasma cortisol levels were analyzed in terms of variation from their respective basal level. After confinement, plasma cortisol levels were not increased in fish submitted to a blue light environment. Thus, blue light prevents the confinement-induced cortisol response, an effect not necessarily related to light intensity

ABSTRACT

O objetivo desse estudo foi determinar e comparar o percentual de gordura, massa corporal magra (MCM) e massa gorda (MG) obtidos pelos métodos da pesagem hidrostática e impedânciabioelétrica em universitários dos sexos masculino e feminino. Para tanto, foram avaliados 115 sujeitos (57 homens e 58 mulheres) entre 18 e 30 anos de idade através da impedância bioelétrica (IB) epesagem hidrostática (PH), que foi o método adotado como critério. O teste t para amostras dependentesrevelou que houve diferença estatística significante, p < 0,001, entre os valores médios das variáveis da composição corporal, apesar da correlação de Pearson entre o %G, MG e MCM decorrente dos dois métodos, terem sido significantes, p < 0,001. Concluímos que a utilização da IB como recurso para as estimativas dos componentes da composição corporal sugere extrema cautela na interpretação dos mesmos...

ABSTRACT

Se evaluo la actividad analgesica y antiinflamatoria del piroxicam en 21 pacientes femeninos, con diagnostico clinico y radiologico de osteoartritis de rodilla. La edad media de las pacientes fue de 63.l anos (51 a 79 anos). Se administro piroxicam en dosis unica de 20 mg/dia durante 90 dias. Los pacientes fueron evaluados cada dos semanas en este periodo. Al finalizar el tratamiento con piroxicam, la intensidad del dolor disminuyo en 58.4% (p< 0.001), la rigidez articular se redujo en 65% (p<0.001). Los pacientes fueron autoevaluados en diferentes escalas para dolor y rigidez articular. El dolor asi evaluado disminuyo en 61% y 70% (p < 0.001); respectivamente. La rigidez articular descendio en 59% (p< 0.001); 9 pacientes manifestaron efectos secundarios durante el tratamiento con piroxicam; los mas frecuentes fueron dolor epigastrico, acidez estomacal y meteorismo, que obligaron a discontinuar el tratamiento en tres pacientes. La rspuesta clinica fue excelente y/o buena en 86% de los casos tratados, y la tolerancia fue excelente y/o buena en 77%. Piroxicam es un nuevo agente antiinflamatorio no esteroideo eficaz en el tratamiento sintomatico de la gonartrosis
