Methamidophos alters sperm function and DNA at different stages of spermatogenesis in mice
(2014)
Methamidophos (MET) is a highly toxic organophosphate (OP) pesticide that is widely used in developing countries. MET has male reproductive effects, including decreased fertility. We evaluated MET effects on sperm quality, ...
Nucleolar organizer regions (NORs) distribution and behavior in spermatozoa and meiotic cells of the horse (Equus caballus)
(2012)
Nucleolar organizing regions (NORs) containing rDNA gene clusters have been assigned to the equine autosomes ECA1, ECA28, and ECA31. Active NORs (Ag-NORs) are associated with argyrophilic proteins, which allow them to be ...
Trypanosoma cruzi populations : more clonal than sexual
(Parasitology Today, 1987-06)
The ancient guestion of trypanosome sexuality has recently been reactivated in view of
important observations in the African species Trypanosoma brucie, in which Mendelian
sexuality has been proposed as o working hypothesis ...
Film processability and properties of polycaprolactone/thermoplastic starch blends
(2012)
Nucleolar organizing regions (NORs) containing rDNA gene clusters have been assigned to the equine autosomes ECA1, ECA28, and ECA31. Active NORs (Ag-NORs) are associated with argyrophilic proteins, which allow them to be ...
Analysis of oocyte-like cells differentiated from porcine fetal skin-derived stem cells
(2011)
We previously reported the differentiation of cells derived from porcine female fetal skin into cells resembling germ cells and oocytes. A subpopulation of these cells expressed germ cell markers and formed aggregates ...

Genetic variability and geographic differentiation among three species of Triatomine bugs (Himiptera- Reduviidae)
(Am. J. Trop Med. Hyg., 1997)
Abstract.
Three species of triatomine bugs, Triatoma sordida, T. guasayana, and T. patagonica, were examined by cytogenetic (C-banded karyotypes and male meiotic process) and isoenzymatic studies. These three species, ...
