TLDR
The general fine structure of intestinal cells and changes which occur in ultrastructure during development from fourth-stage to adult N. dubius are reported and pigment granules are prominent in intestinal cells.Abstract:
The general fine structure of intestinal cells and changes which occur in ultrastructure during development from fourth-stage to adult N. dubius are reported. In fourth-stage worms pigment granules are prominent in intestinal cells. In adults the number of pigment granules appears to be reduced and phagolysosomes containing membranous profiles and pigment material increase in number. Another reorganization of cell structure involves mitochondria which are randomly distributed in the cytoplasm of cells in fourth-stage worms, concentrated in the apical cytoplasm in worms in the molting process, and confined to the base of cells in adult worms. Other changes involved structure of the nucleus, rough endoplasmic reticulum and glycogen content of cells.read more

Ultrastructure of the hypodermis during cuticle formation in the third molt of the nematode Nippostrongylus brasiliensis.
TL;DR: The results were correlated with the fact that the hypodermis in N. brasiliensis is actively synthesizing culticular collagen during the third molt, and morphological changes were associated with transition from the free-living to the parasitic mode in life.

The effect of isatin on the Echinococcus granulosus cyst in an experimental host.
TL;DR: NMRI mice infected with E. granulosus of sheep origin were treated daily with isatin at a dose of 50 mg kg-1 for 18 days, and activity appears as a process of degeneration linked to the alkaline phosphatase inhibitory effect of isatin.

Genic control of the postembryonic development of Nippostrongylus brasiliensis
TL;DR: Large numbers of the free-living stages of Nippostrongylus brasiliensis can be grown synchronously in vitro on formalin-killed Escherchia coli supplemented with cholesterol, which appears to be dosage dependent and is reversible on post-embryonic development.

TL;DR: Results indicate that the metabolized material in the epithelium can contribute to the microfilariae development and also probably can be involved with the excretory/secretory mechanism of these nematodes.
Ciona intestinalis (Tunicata, Ascidiacea)'de Nöral Kompleks Hücrelerinde Zars› Oluflumlar ve Miyelin Benzeri Yap›lar
TL;DR: According to the literature, these structures occur within the cytoplasm of a normal cell, but it was observed that they increase in number and show exhibit greater morphological intricacy in connection with certain physiological events.

A low-viscosity epoxy resin embedding medium for electron microscopy.
TL;DR: A low-viscosity embedding medium based on ERL-4206 is recommended for use in electron microscopy and has a long pot life of several days and infiltrates readily because of its low viscosity.
