Embryonic development of Girardia tigrina (Girard, 1850) (Platyhelminthes, Tricladida, Paludicola)

Dioneia Conceição da Vara, Ana Maria Leal‐Zanchet, Helena Maria Lizardo-Daudt

The embryonic development of freshwater triclads is mainly known from studies of species of Dendrocoelum, Planaria, Polycelis, and, more recently, Schmidtea. The present study characterizes the development of Girardia tigrina (Girard, 1850) by means of optical microcopy using glycol methacrylate semi-thin sections. …

Effects of cadmium chloride on the development of rainbow trout Oncorhynchus mykiss early life stages

Helena Maria Lizardo-Daudt, Christopher J. Kennedy

The sub‐chronic (28–56 days) effects of exposure to low concentrations of cadmium (Cd; 0·05, 0·25, 0·50 and 2·50 μg l−1) shortly following fertilization on embryos, larvae and juvenile rainbow trout Oncorhynchus mykiss were examined. Premature hatching occurred at lower concentrations (0·05 and …

Morphological Aspects of the Embryonic Development of Aegla Platensis (decapoda, Aeglidae)

Helena Maria Lizardo-Daudt, Georgina Bond‐Buckup

The present study characterizes the embryonic development of Aegla platensls Schmitt, 1942 by means of optical microscopy and electron microscopy. The sequence of morphological changes observed in the egg allowed to describe ten embryonic stages: the unsegmented egg, cleavage, bl?stula, gastrula, nauplius, …

Diagnosis of the human fetal age based on the development of the normal kidney

Helena Maria Lizardo-Daudt, Maria Isabel Albano Edelweiss, Fernanda Teixeira dos Santos, Rita de Cássia A. Schumacher

Background and aims: The diagnosis of human fetal age is usually estimated based on the measurement of crown-rump length or crown-heel length and the weight of the fetus. However, this estimate is not totally accurate and sometimes is necessary to combine other …

Histological processing techniques for the study of Dugesiidae development (Platyhelminthes, Tricladida, Paludicola)

Dioneia Conceição da Vara, Ana Maria Leal‐Zanchet, Helena Maria Lizardo-Daudt

The objective of the present study was to adapt techniques for the histological processing of Dugesiidae cocoons for the study of embryo development. The cocoons were fixed with formalin, SUSA, Bouin or paraformaldehyde/glutaraldehyde and subsequently embedded in Paraplast or glycol methacrylate (Historesin). …
