The XY Body of the Cat (Felis catus): Structural Differentiations and Protein Immunolocalization
(Karger, 2017-08)
The heteromorphic X and Y chromosomes behave in a special way in mammalian spermatocytes; they form the XY body and synapse only partially. The aim of this article was to study the origin and the role of the special ...
Dissociation of the X chromosome from the synaptonemal complex in the XY body of the rodent Galea musteloides
(Springer, 2013-09)
The XY body from spermatocy tes of the rodent Galea musteloides shows progressiv e changes of the sy naptonemal complex (SC) axes and the X-chromatin during pachy nema. There is a gross thickening of the X-axis and the ...

Focal spermatogenesis originated in euploid germ cells in classical Klinefelter patients.
(Oxford University Press, 2009-05)
background: Klinefelter syndrome is the most frequent chromosome abnormality in human males. This paper aims to investigate the ploidy of meiotic and pre-meiotic germ cells found in spermatogenic foci, and furthermore, the ...

(2019-02-25)
Las enfermedades cardiovasculares representan la principal causa de muerte a nivel mundial en hombres y mujeres (OMS). Sin embargo, a pesar de que existen evidencias clínicas y experimentales que indican un perfil dimórfico ...
Degeneration of the Y chromosome in evolutionary aging models
(Springer, 2005-06-01)
The Y chromosomes are genetically degenerated and do not recombine with their matching partners X. Recombination of XX pairs is pointed out as the key factor for the Y chromosome degeneration. However, there is an additional ...

An azoospermic man with a double-strand DNA break-processing deficiency in the spermatocyte nuclei: Case report
(Oxford University Press, 2006-05)
BACKGROUND: The mechanisms of meiotic arrest in human spermatogenesis are poorly known. METHODS AND RESULTS: A testicular biopsy from an azoospermic male showed complete spermatogenesis arrest at the spermatocyte stage, ...
