Ultrastructural study of two kinds of muscle in sea anemones: The existence of fast and slow muscles

Autor: Daniel J. Peteya, Helen M. Amerongen

Publikováno v: Journal of morphology. 166(2)

The sea anemones studied have two morphological types of muscle fiber. Types A and B are distinguishable on the basis of myofilament patterns, size of fibers, responses to fixation, and staining with methylene blue. Observation of the muscle in both

Antigen transport by intestinal M cells

Autor: Helen M. Amerongen, Solomon Langermann

Publikováno v: Current Opinion in Gastroenterology. 8:983-987

M cells play a critical role in the generation of protective secretory immunity against intestinal pathogens. For this reason, they have become an important focus for studies on oral vaccine development. In this review, we outline the work on M cells

Effects of Olfactory Bulbectomy, Melatonin, and/or Pinealectomy on Three Sublines of the Dunning R3327 Rat Prostatic Adenocarcinoma

Autor: M. Gail O'Brien, Helen M. Amerongen, Jean G. Toma, William A. McBlain, Scott C. Hennes, Gerald R. Buzzell

Publikováno v: Journal of Pineal Research. 4:321-338

Conventional antiandrogen therapy for prostatic cancer generally results in the death of androgen-dependent cells, resulting in shrinkage of the tumor, followed by regrowth of the tumor as androgen-insensitive cells take over. Because of reported ant

Fine structure of the cerebral organs in hoplonemerteans (Nemertini), with a discussion of their function

Autor: Helen M. Amerongen, Fu Shiang Chia

Publikováno v: Zoomorphology. 107:145-159

The fine structure of the cerebral organs is described in three species of monostiliferous hoplonemerteans. Amphiporus lactifloreus, Paranemertes peregrina and Tetrastemma candidum. There are two distinct groups of sensory cells in the cerebral organ

Behavioural evidence for a chemoreceptive function of the cerebral organs in Paranemertes peregrina coe (hoplonemertea: monostilifera)

Autor: Chia Fu-Shiang, Helen M. Amerongen

Publikováno v: Journal of Experimental Marine Biology and Ecology. 64:11-16

The cerebral organs of nemerteans are complex neuroglandular structures whose function has never been clearly established. In this study, we have investigated the possibility that the cerebral organs in Paranemertes peregrina Coe might be chemorecept

The role of nemertean cerebral organs in salinity stress tolerance re‐examined inParanemertes peregrinacoe (hoplonemertea: Monostilifera)

Autor: Fu Shiang Chia, Helen M. Amerongen

Publikováno v: Marine Behaviour and Physiology. 10:1-22

The role of the cerebral organs of Paranemertes in salinity stress tolerance was investigated by measuring the effect of cerebral organ removal on volume regulation, and by observing the effects of hypo‐osmotic media on the cytology of the cerebral
