The Physiology of Contractile Vacuoles [PDF]
Journal of Experimental Biology, 1936 ABSTRACT On transfer from sea water to dilute sea water, the marine peritrich ciliate Vorticella marina swells more rapidly at higher temperatures. It is concluded that the permeability of the surface of V. marina to water is influenced by temperature, with a Q10 of very roughly 2·5–3·2.

Inhibition of Contractile Vacuole Function by Brefeldin A [PDF]
Plant and Cell Physiology, 2005 Brefeldin A (BFA) causes a block in the secretory system of eukaryotic cells. In the scaly green flagellate Scherffelia dubia, BFA also interfered with the function of the contractile vacuoles (CVs). The CV is an osmoregulatory organelle which periodically expels fluid from the cell in many freshwater protists. Fusion of the CV membrane with the plasma

Paramoeba atlantica as a Natural Intracellular Niche for Vibrios in Marine Ecosystems. [PDF]
Environ MicrobiolVarious vibrios can colonise a large vacuole called VCV (Vibrio‐containing‐vacuole) within Paramoeba atlantica. The VCVs acidify and the vibrios multiply and remain alive inside the VCVs for hours. The vibrio found associated with Paramoeba atlantica can be pathogenic to oysters, suggesting that Paramoebidae are a potential reservoir for pathogens ...

PULSATION OF THE CONTRACTILE VACUOLE OF PARAMECIUM AS AFFECTED BY TEMPERATURE [PDF]
Journal of General Physiology, 1925 1. The rate of pulsation of the anterior contractile vacuole of Paramecium caudatum under chloretone anesthesia has been determined over a range of temperatures from 9–31°C. It has been found that the rate is a logarithmic function of the temperature according to the Arrhenius equation. From 9–16° the temperature characteristic (µ) has the value 25,600;

The role of the host—Neutrophil biology
Periodontology 2000, EarlyView., 2023 Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Frontiers in Marine Science, 2022 Peritrich ciliates are a species-rich group of sessile unicellular eukaryotes, which can be found in various aquatic habitats from all over the world. It is well accepted that there are still many ciliates to be uncovered.

Regulation of contractile vacuole formation and activity in Dictyostelium. [PDF]
EMBO J, 2008 The contractile vacuole (CV) system is the osmoregulatory organelle required for survival for many free-living cells under hypotonic conditions. We identified a new CV regulator, Disgorgin, a TBC-domain-containing protein, which translocates to the CV membrane at the late stage of CV charging and regulates CV-plasma membrane fusion and discharging ...

New Records of Two Stichotrichid Ciliates, Afroamphisiella multinucleata and Pseudokahliella marina (Ciliophora: Spirotrichea: Stichotrichida) from Korea [PDF]
Animal Systematics, Evolution and Diversity, 2012 Two stichotrichid ciliates, collected from marine waters in Jeju Island, were identified as Afroamphisiella multinucleata Foissner et al., 2002 and Pseudokahliella marina (Foissner et al., 1982) Berger et al., 1985.
