RESUMO A mácula dome-shaped consiste na elevação convexa da região macular, encontrada principalmente em pacientes com alta miopia. O significado clínico e a correlação com outras patologias oculares ainda são incertos. Este artigo tem como objetivo descrever dois casos de mácula dome-shaped com acúmulo de fluido sub-retiniano em olhos alto míopes. Trata-se de pacientes com baixa acuidade visual, fundus miopicos e nítida elevação em forma de cúpula na área macular vista na tomografia de coerência óptica. A mácula dome-shaped pode cursar com descolamento seroso da retina neurossensorial envolvendo a fóvea, levando à baixa acuidade visual. Sua patogênese ainda não é bem estabelecida. De acordo com a tomografia de coerência óptica, a mácula dome-shaped pode ser classificada em três tipos morfológicos, sendo, nesses dois casos, demonstrada a disposição oval horizontalizada. Interessante ressaltar que o diagnóstico de mácula dome-shaped deve ser considerado em pacientes alto míopes, especialmente quando há queixa de baixa acuidade visual, que pode estar relacionada à presença de fluido sub-retiniano. Como o exame clínico não permite o diagnóstico adequado da mácula em cúpula, a realização da tomografia de coerência óptica com cortes verticais e horizontais é fundamental na suspeita de mácula dome-shaped.

ABSTRACT Dome-shaped macula consists of the convex elevation of the macular region, found mainly in patients with high myopia. The clinical significance and the correlation with other ocular pathologies are still uncertain. This article aims to describe two cases of dome-shaped macula with accumulation of subretinal fluid in high myopic eyes. Those are patients with low visual acuity, myopic fundus and a clear dome-shaped elevation in the macular area at optical coherence tomography. A dome-shaped macula can course with a serous detachment of the sensorineural retina involving the fovea, leading to low visual acuity. Such a pathogenesis is still not well studied. According to the optical coherence tomography, dome-shaped macula can be classified into three morphological types, those two cases being shown in a horizontal, oval arrangement. It is interesting to note that the diagnosis of dome-shaped macula should be considered in patients with high myopia, especially when there is a complaint of low visual acuity, which may be related to the presence of subretinal fluid in cases of dome-shaped macula. As the clinical examination does not allow an adequate diagnosis of the domed macula, the performance of the optical coherence tomography with vertical and horizontal cuts is fundamental in the suspicion of the dome-shaped macula.

ABSTRACT Sinningia rupicola (Gesneriaceae), espécie ameaçada de extinção e classificada como endêmica de canga do Quadrilátero Ferrífero é aqui apresentada sob uma abordagem ecológica, baseada na análise de dados referentes a registros realizados em duas Reservas Particulares do Patrimônio Natural (RPPN) da empresa Vale, situadas no Quadrilátero Ferrífero, Estado de Minas Gerais, Brasil: Capanema e Poço Fundo. O estudo visou caracterizar a população da espécie quanto ao número de indivíduos, área de ocupação (AOO), extensão de ocorrência (EOO) e aspectos ambientais dos locais de registros relacionados à topografia, cobertura vegetal e litologia, além de avaliação do substrato, micro-habitat e fenologia. Foram registrados 1.397 indivíduos, sendo 1.254 na RPPN Capanema e 143 na RPPN Poço Fundo. As populações foram registradas colonizando rochas Quartzíticas, em altitudes que variaram entre 1.400 e 1.600 m. As populações foram caracterizadas como predominantemente saxícolas, encontradas em floração entre janeiro e março e com frutos entre fevereiro e março. Os resultados obtidos neste estudo demonstram a ocorrência de Sinningia rupicola em litologias variadas, o que sugere que a distribuição da espécie em ambientes naturais é mais ampla do que a até então presumida.

RESUMO Sinningia rupicola (Gesneriaceae), an endangered species classified as endemic to the cangas of the Quadrilátero Ferrífero is presented here under an ecological approach. It was based on data analysis of two populations sampled in the Private Natural Heritage Reserves (RPPN) Capanema and Poço Fundo belonging to the company Vale S.A., located at the Quadrilátero Ferrífero, state of Minas Gerais, Brazil. The study aimed to characterize the populations of the species regarding the number of individuals, area of occupancy (AOO), extent of occurrence (EOO) and the environmental aspects of the record sites. The populations were related to topography, hydrography, vegetation cover and lithology, as well as substrate, micro-habitat and phenology evaluation. In total, it was registered 1,397 individuals, 1,254 at RPPN Capanema and 143 at RPPN Poço Fundo. The populations were found occurring on quartzitic rocks, at altitudes ranging from 1,400 to 1,600 m. The populations were characterized as predominantly saxicolous, flowering between January and March and with fruits between February and March. The results obtained in this study demonstrate the occurrence of Sinningia rupicola in varied lithologies suggesting that its occurrence in natural environments may be wider than previously assumed.

ABSTRACT The objective of this study was to evaluate the effects of dietary nucleotide supplementation on growth performance, serum immunoglobulin G (IgG) and uric acid levels, immune-related organs, and intestinal morphometric parameters of broiler chickens under pre- and post-inflammatory challenge with lipopolysaccharide (LPS). Ninety-six seven-day-old male broiler chicks were randomized in a 2×2 factorial design composed of two dietary types (supplemented with 0 and 0.3 g of purified nucleotides/kg of feed) and two inflammatory conditions (with and without LPS administration) with eight replicates per treatment and three birds per cage. The experimental period was divided into two phases: 7-20 days of age (pre-LPS challenge) and 21-35 days of age (post-LPS challenge). Data were analyzed using one-way and two-way ANOVA for the pre- and post-challenge phases, respectively. During the pre-challenge phase, dietary nucleotide supplementation improved body weight (982 vs. 1009 g/bird), daily weight gain (58.1 vs. 60.1 g/bird), feed conversion rate (1.28 vs. 1.25 g/g), and serum concentration of IgG (1.17 vs. 1.76 mg/mL) of broilers. During the post-challenge phase, nucleotide supplementation increased serum IgG of broilers at 28 days of age (3.01 vs. 4.34 mg/mL). For the intestinal morphometric parameters, nucleotide supplementation increased villus height (299.3 vs. 315.6 μm). Dietary nucleotide supplementation improves the performance of broilers from seven to 20 days of age (pre-LPS challenge). However, from 21 to 35 days of age, supplementation of 0.3 g of purified nucleotides/kg of feed, independent of inflammatory challenge, does not contribute to improve performance of broilers. Additionally, nucleotide supplementation increases IgG production and villus height in the jejunum of broilers.

ABSTRACT: This study was undertaken to evaluate the effects of dietary calcium levels and supplementation with organic trace minerals selenium, copper, iron, zinc and manganese on performance, tissue deposition and litter mineral concentration. A total of 2,496 one-day-old male Cobb 500 broilers were randomly assigned to a 3 × 4 factorial experimental design with three levels of dietary Ca [8, 10 and 12 g kg–1, while maintaining the same Ca:nPP (non-phytate phosphorus) ratio (2:1)] and four levels of micromineral supplementation (0.62, 0.72, 0.82 and 0.92 g kg–1). There was a total of 12 treatments, with eight replicates of 26 birds per pen. Micromineral supplementation (MS) was achieved by adding different levels of the product Bioplex TR Se® and Ca supplementation was achieved by adding increasing levels of limestone and dicalcium phosphate. An interaction between Ca and MS levels was observed (p < 0.05) for the parameters of performance, liver Cu concentration, breast Se and Cu concentrations and litter Se, Mn and Zn concentrations. No interactions were observed (p > 0.05) for Ca, P or ash concentrations in the tibia, which were influenced only by dietary Ca levels (p < 0.05). The Ca level of 10 g kg–1 promoted higher Ca and P concentration in the tibia and lower micromineral excretion in the litter. The combination of MS level of 0.82 g kg–1 with Ca level of 10 g kg–1 led to the best BWG response. The supplementation conditions that led to higher micromineral levels in the liver and breast varied for each mineral.

ABSTRACT This study was conducted to determine the optimal standardized ileal digestible arginine to lysine (SID Arg:Lys) ratio for Japanese quails in the egg-laying phase. A total of two hundred forty-five 35-week-old Japanese quails (181 ± 1.30 g initial body weight) were randomly assigned to five treatment groups with seven replicates of seven quails. Graded levels of L-Arginine were added to a basal diet in order to produce five SID Arg:Lys ratios (101, 106, 111, 116 and 121%). Collected data were analyzed as one-way ANOVA and optimal ratio was estimated using polynomial regression model (linear and quadratic) based on performance traits. Statistical differences were considered for p<0.05. Graded SID Arg:Lys ratios did not affect performance traits assessed. Based on results, the SID Arg:Lys ratio of 101% is sufficient to warrant proper performance of Japanese quails in the egg-laying phase.

ABSTRACT This experiment was conducted to evaluate the effects of dietary nitrogen-corrected apparent metabolizable energy (AMEn) levels on meat-type quail performance and carcass traits from 1 to 14d of age. A total of 1120 not sexed meat-type quails were randomly distributed to seven treatments, with eight replicates with 20 quails each. A basal corn and soybean meal-based diet was formulated to meet or exceed quail nutritional requirements, except for ME. Graded levels of soybean oil were added to the basal diet in replacement, to sand, to obtain dietary treatments (2,600; 2,700; 2,800; 2,900; 3,000; 3,100 and 3,200 KcalAMEn/kg diet). Data were analyzed as one-way ANOVA and optimum AMEn levels were estimated using polynomial regression model. Increasing in dietary AMEn levels elicited a linear decrease (p<0.01) in feed intake and nutrient intake (AMEn, protein and lysine). Quail weight gain and final body weight exhibited a quadratic response (p<0.03) to increased AMEn levels, being both optimized at 2820 KcalAMEn/kg diet. Graded AMEn levels elicited a linear increase (p<0.01) in carcass dry matter and fat content, whereas moisture content was linearly decreased (p<0.01). The protein content of the carcasses was not influenced (p>0.05) by AMEn. Based on the results, the dietary AMEn level that warrants adequate performance and carcass traits of meat-type quails from 1 to 14d of age is 2,820 Kcal/kg diet.

ABSTRACT This study was conducted to determine the optimum standardized ileal digestible isoleucine to lysine (SID Ile:Lys) ratio for meat-type quails from 15 to 35 d of age. Three hundred fifty not-sexed meat-type quails (Coturnix coturnix coturnix) were randomly assigned into five treatments, with seven replicates of 10 quails each. An isoleucine-deficient corn-soybean meal-based diet was formulated and graded supplemented with L-isoleucine (99%) to obtain diets containing SID Ile:Lys ratios of 55,61, 67, 73, and 79%. Data were analyzed as one-way ANOVA and optimum SID Ile:Lys was estimated by polynomial (linear and quadratic) regression. Statistical differences were considered when p<0.05. Quail performance from 15 and 21 d and 15 and 28 d of age was not affected by the treatments. From 15 to 35 d of age, body weight gain and body weight exhibited a quadratic response to increasing dietary SID Ile:Lys ratios, and were optimized at 66 and 67% SID Ile:Lys, respectively. Feed conversion ratio was not influenced by SID Ile:Lys ratios in any of the phases assessed herein. Based on the results, the optimum SID Ile:Lys ratio for meat-type quails from 15 to 35 d of age is 67%.

ABSTRACT This study was conducted to estimate the dig. valine to lysine (Val:Lys) ideal ratio for meat-type quails from 15 to 35 d of age. A total of 385, 15-day-old not sexed quails, were randomly assigned to five treatments, each one seven times replicated with eleven quails per experimental unit. Experimental treatments consisted of five dig. Val:Lys ratios (0.65; 0.70; 0.75; 0.80 and 0.85). Ideal dig. Val:Lys ratio was estimated using polynomial regression and linear broken-line regression model. Significant effect was considered when p≤0.05. Feed conversion ratio was not affected by dig. Val:Lys ratios in any of the assessed phases. From 15 to 21 d of age Val:Lys ratios increased linearly feed intake, weight gain and body weight. From 15 to 28 d of age, weight gain and body weight were both optimized by the Val:Lys ratio of 0.77. A linear effect of dig. Val:Lys ratios was observed on weight gain and final body weight from 15 to 35 d of age. From 15 to 35 d of age, according to linear broken-line regression model, the dig. Val:Lys ideal ratios for optimum final body weight and weight gain were 0.77 and 0.76, respectively. Based on the results the estimated dig. Val:Lys ratio for optimum meat-type quail performance from 15 to 35 d of age is 0.77

RESUMO: Com o objetivo de avaliar o efeito dos níveis de energia metabolizável (EM) sobre o desempenho de codornas de corte de 15 a 35 dias de idade, foi conduzido um experimento com 560 aves aos 15 dias de idade, distribuídas em delineamento inteiramente casualizado com cinco tratamentos (2.850; 2.950; 3.050; 3.150 e 3.250kcal de EM kg-1 de ração), oito repetições com 14 aves por unidade experimental. Verificou-se redução linear (P<0,01) no consumo de ração, de proteína, de lisina e na conversão alimentar, com o aumento dos níveis de EM da ração. O consumo de energia metabolizável, o peso corporal, o ganho de peso, viabilidade das aves não foram influenciados (P>0,05) pelos níveis de EM utilizados. Os níveis de EM das dietas não influenciaram (P>0,05) a matéria seca, o teor de umidade e a proteína nas carcaças. Foi observado efeito quadrático (P<0,04) dos níveis de EM sobre o teor de gordura nas carcaças. Conclui-se que o nível de EM de 3.250kcal kg-1 de ração, correspondendo à relação de energia metabolizável:proteína bruta de 139,24, possibilita melhor desempenho das codornas de corte.

ABSTRACT: This trial was carried out to evaluate the effects of dietetic metabolizable energy levels on performance and carcass traits of meat quails from 15 to 35 days old. Five hundred sixty, 15-d old, meat quails were randomly assigned to five treatments (2.850; 2.950; 3.050; 3.150 e 3.250kcal of ME kg-1 of diet), with eight replicates and fourteen birds per experimental unit. Feed intake, protein and lysine intake and feed conversion decreased linearly as the metabolizable energy content of diets increased (P<0.01), whereas metabolizable energy intake, body weight, weight gain and viability were not affected (P>0.05) by the treatments. Diets did not influence (P>0.05) carcass traits as dry matter, moisture and protein content in carcass. However a quadratic effect (P<0.04) were observed on carcass fat content. Based on these results, the adequate metabolizable energy level to ensure better meat quails' growth is 3.250kcal of ME kg-1 diet, that corresponds to a metabolizable energy: crude protein ratio of 139,24.

ABSTRACT Two trials were performed to evaluate the effects of an enzyme complex (EC) on broiler performance, metabolizable energy, and phosphorus and nitrogen balance. In the first trial, 960 one-day-old male Cobb broilers were randomly distributed in a 3 x 2 factorial arrangement (three nutritional levels and the inclusion or not of EC), totaling six treatments with eight replicates of 20 birds per pen, and reared until 42 days of age. The control diet was formulated to meet the broilers' nutritional requirements. The other diets contained reduced available phosphorus (P), metabolizable energy, and amino acid levels, considering 100% and 150% of the EC nutritional matrix. The inclusion of the EC (200 g/ton) resulted in better broiler performance, improving weight gain in 4% and feed conversion ratio in 3% (p< 0.05). In the second trial, 240 male broilers were randomly distributed into the same treatments with eight replicates of five birds per cage. The method of total excreta collection was used. There was an interaction (p< 0.05) between diets and EC for P intake, nitrogen (N) intake, and N retention. The EC supplementation improved nitrogen-corrected apparent metabolizable energy values in 2.02% (p< 0.05). Significant effects were observed on phosphorus and nitrogen balance (p< 0.05). Phosphorus retention improved in 10.26%, nitrogen retention increased in 5.3%, while nitrogen excretion decreased in 3.3%. Based on the results of the present study, we recommend the addition of 200 g/t of the enzyme complex to broiler diets, considering nutrient reduction based on 100% of the EC nutritional matrix.

ABSTRACT The use of gels and mouthrinses with MMP inhibitors (chlorhexidine, and green tea extract) was shown to prevent erosive wear. The aim of this study was to analyze the protective effect of toothpastes containing MMP inhibitors on dentine loss induced by erosion in vitro. Material and Methods Five groups each containing 12 specimens of human root dentine were prepared. The specimens were subjected to 1 min erosion by immersion in a cola drink, 4 times a day, for 5 d. Each day, after the first and last erosive challenges, the specimens were brushed for 15 s with a slurry of dentifrice and water (1:3) containing placebo, 1,100 ppm fluoride, 0.61% green tea extract, 0.12% chlorhexidine or 0.004% chlorhexidine (commercial toothpaste). Between the acid challenges, the specimens were stored in artificial saliva with remineralizing potential until the next treatment. Dentine loss was determined using profilometry. Data were analyzed using one-way ANOVA after log transform (p<0.05). Results The mean wear values (μm) were as follows: placebo 1.83±0.53; 0.61% green tea extract 1.00±0.21; fluoride 1.27±0.43; 0.12% chlorhexidine 1.19±0.30; and 0.004% chlorhexidine 1.22±0.46. There was a significant difference in wear between placebo and all the treatment toothpastes, which did not differ from each other. Conclusion The results suggest that toothpastes containing MMP inhibitors are as effective as those based on NaF in preventing dentine erosion and abrasion.

ABSTRACT This study aimed at evaluating four dietary L-Glutamine (L-Gln) or L-Gln plus L-Glutamate (L-Glu) supplementation programs on the performance, breast yield, and uniformity of broilers. A total of 2,112 one-d-old male Cobb 500(r) broilers were distributed according to a randomized block design in a 2 × 4 factorial arrangement (L-Gln or L-Gln plus L-Glu × 4 supplementation programs), totaling eight treatments with 12 replicates of 22 broilers each. The supplementation programs consisted of the dietary inclusion or not of 0.4% of L-Gln or L-Gln plus L-Glu for four different periods: 0 days (negative control), 9d, 21d, and 42d. Feed intake (FI, g), body weight gain (BWG, g), feed conversion ratio (FCR, kg/kg), coefficient of variation of body weight (CV, %), body weight uniformity (UNIF, %), breast weight (BW, g), breast yield (BY, %), coefficient of variation of breast weight (CVB), breast uniformity (UNIFB), coefficient of variation of breast yield (CVBY), and breast yield uniformity (UNIFBY) were evaluated. Birds fed the diets treatments supplemented with L-Gln or L-Gln plus L-Glu for 9d presented 3% higher BWG (p<0.05) compared with the controls. The L-Gln or L-Gln plus L-Glu supplementation until broilers were 21 days old resulted in 14, 10, 16, and 12% improvements (p<0.05) in CV, UNIF, CVBY, UNIFBY, respectively. The supplementation of 0.4% L-Gln (L-Gln 99%) or L-Gln plus L-Glu (minimum 95%) to pre-starter and starter broiler diets is recommended to improve body weight gain and uniformity.

Resumo Foram avaliados os efeitos da adição de diferentes níveis de betaína (0,0%, 0,1%, 0,2%, 0,3%) sobre a morfologia do intestino delgado. Foram utilizados 52 leitões desmamados aos 23 dias de idade e peso médio de 5,4 kg, quatro níveis de betaína e cinco épocas de abate. Foram efetuados cinco abates, com intervalos de três dias, considerando o dia da desmama como o dia zero. Foram avaliadas altura de vilosidade e profundidade de criptas. Foram observadas diferenças significativas (P<0,05) entre os tratamentos para altura das vilosidades no duodeno e para profundidade de criptas do íleo. Em relação aos dias pós-desmama, ocorreram diferenças significativas (P< 0,05) para altura de vilosidades e profundidade de criptas nos três segmentos intestinais analisados.

Abstract We evaluated the effects of increasing levels of betaine (0.0%, 0.1%, 0.2%, 0.3%) on small intestine structure. Fifty-two weaned piglets at 23 days of age and average weight of 5.4 kg were used. We studied four betaine levels and five slaughtered times with three days of interval, considering the weaning day as the initial day (zero day). We evaluated villi height and crypt depth. We observed significant differences (P<0.05) among treatments for villi height in duodenum and for crypt depth in ileum. Regarding post-weaning days, significant differences (P<0.05) in villi height and crypt depth occurred in the three intestinal segments analyzed.

ResumoEste estudo foi realizado com o objetivo de determinar as digestibilidades aparente e estandardizada de fosfatos para suínos em fase de crescimento, empregando duas metodologias. Foram usados 42 machos castrados, mestiços, com peso inicial de 37 ± 1,1kg em delineamento de blocos casualizados, em esquema fatorial 2 x 7, com dois métodos de coleta: coleta total de fezes e uso de indicador (cinza insolúvel em ácido [AIA ]) × sete tratamentos, que consistiram de uma dieta controle (CTR); três dietas contendo fosfato na forma de pó (PP): PPA = CTR + fosfato pó A, PPB = CTR + fosfato pó B, e PPC = CTR + fosfato pó C; e mais três dietas contendo o fosfato microgranular (MP): MP15 = CTR + fosfato microgranular 15%, MP45 = CTR + fosfato microgranular 45% e MP75 = CTR + fosfato microgranular 75%). Os valores de 15, 45, e 75% correspondem à solubilidade em água dos fosfatos. Foram seis repetições, e o animal foi considerado como unidade experimental. Os coeficientes de digestibilidade estandardizada dos fosfatos avaliadas pelo método de coleta total, em valores percentuais, foram: PPA = 86,9, PPB = 84,9, PPC = 81,9, MP15 = 89,4, MP45 = 88,8, e MP75 = 92,6. Os coeficientes de digestibilidade total estandardizada dos fosfatos avaliados pelo método do indicador, em valores percentuais foram: PPA = 75,9, PPB = 75,4, PPC = 75,6, MP15 = 84,9, MP45 = 78,0, e MP75 = 79,4. Considerando as duas metodologias avaliadas no presente trabalho, os fosfatos microgranulares constituem a melhor alternativa para a alimentação de suínos em fase de crescimento.

AbstractThis study was realized with the objective to determine the apparent and standardized digestibilities of phosphates to pigs in growing phase, employing two methodologies. Forty-two crossbred barrows with an initial weight of 37 ± 1.1kg were used in a randomized-block design in a 2 × 7 factorial arrangement, with two collection methods: total fecal collection and the use of a indicator (acid insoluble ash [AIA]) × seven treatments, which consisted of a control diet (CTR); three diets containing phosphate in powder form (PP): PPA= CTR + powder phosphate A, PPB= CTR + powder phosphate B, and PPC= CTR + powder phosphate C; and another three diets containing the microgranular phosphate (MP): MP15= CTR + microgranular phosphate 15%, MP45 = CTR + microgranular phosphate 45% and MP75= CTR + microgranular phosphate 75%). The values of 15, 45, and 75% correspond to the water-solubility of the phosphates. There were six replicates, and the pig was considered as experimental unit. The standardized digestibility coefficients of the phosphates assessed by the total collection method, in percent values, were: PPA = 86.9, PPB = 84.9, PPC = 81.9, MP15 = 89.4, MP45 = 88.8, and MP75 = 92.6. The standardized-digestibility coefficients of the phosphates evaluated by the indicator method (AIA) in percent values were: PPA = 75.9, PPB = 75.4, PPC = 75.6, MP15 = 84.9, MP45 = 78.0, and MP75 = 79.4. Considering the two methodologies evaluated in the present work, the microgranular phosphates constitute the best alternative for feeding pigs in the growth phase.
