25. A new partial diallel model adapted to analyze reciprocal effects in grain yield of maize
Abstract Comparison between two distinct groups using a partial diallel and considering reciprocal effects has not been described in the scientific literature, limiting diallel analysis results. This study compared two groups of parents using a partial diallel, and analyzed the general and specific combining ability and reciprocal effects, divided into mater

27. Neonatal mortality associated with sodium monofluoracetate in kids fed with colostrum from goats ingesting Amorimia septentrionalis
RESUMO: Mortes súbitas, após a ingestão do colostro, em cabritos e cordeiros nascidos de mães que pastejam em áreas com Amorimia septentrionalis são relatadas no semiárido da Paraíba. O objetivo deste trabalho foi determinar se o monofluoracetato de sódio (MF) contido em Amorimia septentrionalis é eliminado pelo leite, causando a morte dos cabritos

28. Mixed infection by Histoplasma capsulatum isolates with different mating types in Brazilian AIDS-patients
ABSTRACT Mixed infection by Histoplasma capsulatum isolates with different mating types, in AIDS-patients are described in this study. Morphological, mating type-specific PCR assay and multilocus sequencing type analysis of H. capsulatum isolates recovered from two Brazilian AIDS-patients were performed. Five H. capsulatum isolates were recovered at differen

29. Relative growth of freshwater prawn Macrobrachium brasiliense (Decapoda, Palaemonidae) and its implications for reproduction
RESUMO O objetivo principal deste estudo foi estimar a maturidade sexual morfológica de Macrobrachium brasiliense (Heller, 1862) e analisar o crescimento relativo da espécie. Durante um ano de coleta, de julho de 2012 a junho de 2013, foram coletados 199 espécimes em um riacho localizado em um bioma de Cerrado, na região do Triângulo Mineiro. Uma vez id

30. Multiplex polymerase chain reaction as an improved method for screening Histoplasma capsulatum mating types
Histoplasmosis is a systemic mycosis infection caused by Histoplasma capsulatum, a heterothallic ascomycete. The sexual reproduction of this fungus is regulated by the mating type (MAT1) locus that contains MAT1-1 and MAT1-2 idiomorphs, which were identified by uniplex polymerase chain reaction (PCR). This study aimed to optimise single-step multiplex PCR fo

31. Partum and postpartum characteristics on the postpartum rebreeding in beef cattle
ABSTRACT The objective was to evaluate the influence of calving and postpartum characteristics, measured in different genetic predominance, on the postpartum rebreeding. Were evaluated 437 partum from cows that received feeding management consisting of a forage base of the native field and the mating season consisted of 90 days. The measurements were used fr

32. Ecology of the snake Atractus paraguayensis (Dipsadidae) in southern Brazil
ABSTRACT Knowledge of snake ecology is important to support conservation strategies. Atractus paraguayensis Werner, 1924 is a dipsadidae with semi fossorial habits distributed throughout southern Brazil. We analyzed the morphology, seasonality and reproductive biology of this species in a subtropical area in southern Brazil by combining material from scienti

33. Investigation of the effect of gestational diabetes on fetal cardiac tissue in streptozotocin ınduced in rats
Abstract Purpose: To investigate the cause of congenital anomalies resulted from gestational diabetes on fetal cardiac tissue in experimental animal study model. Methods: Totally 12 female Wistar albino rats were divided into two groups, each consisting of 6 rats. Streptozotocin (60 mg/kg) was administered intraperitoneally to the study group by dissolving

34. Genetic diversity and population structure of Vriesea reitzii (Bromeliaceae), a species from the Southern Brazilian Highlands
Abstract The Southern Brazilian Highlands are composed by a mosaic of Mixed Ombrophilous Forest (MOF) and grassland formations, an interesting landscape for the study of population structure. We analyzed the genetic diversity within and among populations of the MOF-endemic bromeliad Vriesea reitzii by genotyping seven nuclear microsatellite loci in 187 indiv

35. New microsatellite loci for annatto (Bixa orellana), a source of natural dyes from Brazilian Amazonia
Abstract Annatto (Bixa orellana) is a tropical crop native to the Americas with Amazonia as the likely center of origin of domestication. Annatto is important because it produces the dye bixin, which is widely used in the pharmaceutical, food, cosmetic and textile industries. A total of 32 microsatellite loci were isolated from a microsatellite-enriched geno

36. Development and reproductive performance of Hereford heifers of different frame sizes up to mating at 14-15 months of age
ABSTRACT Body development and reproductive performance of a hundred forty-two 14 to 15-month-old heifers, classified at weaning according to frame size as small, medium, and large, were evaluated. The parameters evaluated were: body weight, hip height, body condition score, weight gain, ovarian activity, and pregnancy rate. At weaning, body weight and hip he
