This study investigates the basic assumption of homogeneity of monozygotic (MZ) twins: are there differences according to the timing of the zygotic splitting, early in dichorionic (DC) and later in monochorionic (MC) pairs? We assessed the IQ of 451 same-sexed twin pairs of known zygosity and chorion type with the Wechsler Intelligence Scale for Children-Revised (WISC-R). The variances of withi...

The study aims to describe the perception of seniors on the exercise of citizenship in the light of the thought of Maurice Merleau-Ponty, based on the notion of the sexed body and the other's body. Discloses was from the participation of 13 elderly, members of acquaintance groups in the city of Jequié/BA, which produced experiential descriptions in three focus group meetings, during the month o...

This paper criticises John Harris's attempts to defend an account of a 'harmed condition' that can stand independently of intuitions about what is 'normal'. I argue that because Homo sapiens is a sexually dimorphic species, determining whether a particular individual is in a harmed condition or not will sometimes require making reference to the normal capacities of their sex. Consequently, Harr...

The sperm quality index (SQI) is predictive of fresh semen quality. Our objective was to examine if semen storage affects the SQI obtained from undiluted semen, or semen diluted with either Beltsville Poultry Semen Extender (BPSE) or Minimum Essential Medium (MEM) and held for 8 h at 4, 21, or 41 C. Dead o sperm percentage was higher and SQI was lower from undiluted versus diluted semen. Dead s...

Because a growing proportion of the beef output in many countries originates from dairy herds, most critical decisions about genetic merit carcasses harvested are being made by producers. Interest generation more valuable calves females is intensifying, and likely vehicle use appropriately selected bulls for mating to females. This especially true given potential undertake × matings as herd met...

Purpose: To determine the clinical relevance of determining the semen pH during semen analysis as per WHO (World Health Organisation) standard criteria among the infertile couple attending a tertiary ART (Assisted Reproductive Technology) Centre in South India. Methods: Regular Semen analysis as per WHO standards (2010) Results: The Semen pH value showed no major correlation with other Semen pa...

Germ cell differentiation in reverse-sexed reproductive organs and interspecies germ line chimeras provides insight into the mechanism of germ cell development and represents a useful tool for conservation of endangered birds. We investigated the migration and survival capacity of male chicken primordial germ cells (PGCs) in female chicken embryos and in quail and Korean ring-necked pheasant em...

Phenotypic sexual dimorphism seems to be rare in the Ramphastidae family, except in Pteroglossus viridis and in the genus Selenidera. Many breeders of wild birds believe that specimens of Ramphastos toco can be sexed using bill characteristics. In this study, various discriminant phenotypic variables were analyzed in birds which were sexed cytogenetically. Fifty-one specimens of R. toco and 20 ...

Campylobacter and Salmonella are the most commonly reported pathogens causing foodborne illness in the United States. In turkeys, the potential that semen used for artificial insemination is contaminated with these foodborne pathogens has not been investigated. Because semen on turkey farms is pooled and then used to inseminate multiple hens, contaminated semen could easily spread these bacteri...
