Structure and development of the egg of the glossiphoniid leech Theromyzon rude: Characterization of developmental stages and structure of the early uncleaved egg
(1987)
Some aspects of the reproductive biology of the glossiphoniid leech, Theromyzon rude, under laboratory conditions, and the staging and structure of its uncleaved egg were studied. Sexually mature animals form breeding ...

Detection of sugar residues in lizard tooth germs (Liolaemus gravenhorsti) using lectin histochemistry
(1994)
The appearance, cellular distribution, and changes of sugar residues during tooth development in adults of the polyphyodont, Liolaemus gravenhorsti, were investigated by using horseradish–peroxidase–conjugate lectins ...
Localization of peroxidase activity in blood mononuclear phagocytes in pacu fish (Piaractus mesopotamicus)
(2002-10-01)
The localization of peroxidase activity in different cell regions is used as a criterion for classifying the stage of maturity of mammalian mononuclear phagocytes, with a positive peroxidase reaction indicating the presence ...

Comparative analysis of the development of the lizard, Liolaemus tenuis tenuis. II. A series of normal postlaying stages in embryonic development
(1981)
In this work, we have completed a study of the development of the ovoviviparous lizard Liolaemus tenuis tenuis. Ovoviviparity in this lizard is a condition in which eggs are retained within the reproductive duct for about ...
An updated insight into the Sialotranscriptome of Triatoma infestans: developmental stage and geographic variations
(Public Library of Science, 2014)
BACKGROUND: Triatoma infestans is the main vector of Chagas disease in South America. As in all hematophagous arthropods, its saliva contains a complex cocktail that assists blood feeding by preventing platelet aggregation ...

Factors that interfere with oocyte quality for in vitro production of cattle embryos: Effects of different developmental & reproductive stages
(2016-01-01)
The success of IVP is ultimately dependent on the number and quality of the cumulus-oocyte complexes (COC) harvested during the OPU procedure. Several factors appear to be critical to oocyte quality including follicle size, ...
Cytological characterization of the germinal line during testicular differentiation in the lizard Liolaemus gravenhorsti (gray)
(1982)
The gross morphology, histology, and ultrastructure of Liolaemus gravenhorsti gonads prior to and after differntiation are described. Special emphasis has been given to characterization and changes of the germ cell line ...
