| The aim of this research was to use a system of 37 variables of morphological characteristics on a sample of 108 elite male athletes (25 karatekas, 27 judokas, 19 taekwondoists, 18 boxers and 19 wrestlers), aged 17 to 23, to determine any statistically significant differences between the groups of athletes in terms of variable means, so that during the training process, the selection of athletes could be carried out in a proper and objective manner and that the training transformation processes could be managed more effectively. After processing the data using the statistical method of a multivariate and univariate analysis of variance (MANOVA/ANOVA), we obtained results that indicate that among the karatekas, judokas, taekwondoists, boxers and wrestlers... |

| The assessment of body composition provides a basis for evaluating changes in adults as they age. If the fat content is shown to be too high, intervention to reduce storage fat is warranted. The purpose of this paper is to report differences in body composition in men and women across three age groups (young, middle aged, older) to describe potential changes in both fat and muscularity. In addition, if fat storage is shown to be located in the visceral area (around the internal organs), then an addition risk to health would be evident. A total of 1564 Hungarian adults were tested for body mass index (BMI) and body composition using a multi-frequency electrical impedance device to determine percent body fat (PBF), percent muscularity (M%), and visceral fat... |

| Resumo: Em dez ovinos deslanados das racas Santa Ines e Somalis brasileira, sendo cinco de cada, foi coletado e ejaculado espermatico, atraves da vagina artificial, durante um ano. O objetivo foi avaliar a atividade sexual do macho ovino, nas condicoes do Nordeste brasileiro, no periodo seco (agosto a dezembro de 1983) e chuvoso (janeiro a maio de 1984) e as diferencas entre racas. Na avaliacao do esperma houve uma diferenca (P<0,001) entre racas, a Santa Ines mostrando maior volume e concentracao do que a Somalis brasileira. Nao se obtiveram diferencas quanto a porcentagem de espermatozoides vivos e motilidade progressiva. Na epoca seca, o volume e a concentracao foram menores que na epoca chuvosa (P<0,001). Porem a porcentagem de espermatozoides... |

| Daphnia reproduce by cyclic-parthenogenesis, where phases of asexual reproduction are intermitted by sexual production of diapause stages. This life cycle, together with environmental sex determination, allow the comparison of gene expression between genetically identical males and females. We investigated gene expression differences between males and females in four genotypes of Daphnia magna and compared the results with published data on sex-biased gene expression in two other Daphnia species, each representing one of the major phylogenetic clades within the genus. We found that 42% of all annotated genes showed sex-biased expression in D. magna. This proportion is similar both to estimates from other Daphnia species as well as from species with genetic... |
