The resting cysts of modern marine dinoflagellates and their palaeontological significance

Review of Palaeobotany and Palynology, 1967
Abstract Study of resting cysts produced by 25 species of thecate marine dinoflagellates belonging to five genera (Gonyaulax, Protoceratium, Peridinium, Diplopsalis, and Diplopsalopsis) stresses the fact that these cysts are often identically with or phylogenetically closely related to certain Tertiary and Quaternary hystrichospheres and fossil ...

Chrysophyte reproduction and resting cysts: A paleolimnologist's primer

Journal of Paleolimnology, 1991
Chrysophyte algae produce siliceous resting cysts (stomatocysts) that are becoming an increasingly useful class of paleoecological indicator microfossils. This paper provides a review of the role that stomatocysts play in the life cycle and reproductive ecology of freshwater planktonic chrysophytes.

Green light-mediated photomorphogenesis in a dinoflagellate resting cyst

Nature, 1986
Developmental responses to light are well known and ubiquitous among higher plants1, but examples of such responses among the algae are less common. Those responses which have been reported in this group are generally photoperiodic or require prolonged light exposures; most involve macrophytes2.

Ultrastructure of the macronucleus in the resting cysts of the ciliate Bursaria truncatella

European Journal of Protistology, 1998
Summary The ultrastructure of the macronucleus and the micronucleus in the resting cysts of the ciliate Bursaria truncatella was studied by electron microscopy. The data obtained were compared with those for B. truncatella mature vegetative cells.

Role of resting cysts in Chilean Alexandrium catenella dinoflagellate blooms revisited

Harmful Algae, 2016
The detection of sparse Alexandrium catenella-resting cysts in sediments of southern Chilean fjords has cast doubts on their importance in the recurrence of massive toxic dinoflagellate blooms in the region. The role of resting cysts and the existence of different regional Chilean populations was studied by culturing and genetic approaches to define ...

MicroRNA Dissects Out Dangerous Pancreatic Cysts from All the Rest

Clinical Cancer Research, 2012
Abstract Malignant transformation of pancreatic cysts occurs in only a fraction of patients. The diagnostic dilemma is identifying which cysts pose a cancerous threat. Cyst fluid has been analyzed in a variety of ways to answer this question but the microRNA (miRNA) profile of the fluid may finally hold the answer. Clin Cancer Res; 18(

Resting Cyst Formation as a Strategy for Environmental Adaptation in Colpodid Ciliates

Zoological Science
Resting cyst formation is a strategic aspect of the life cycle of some eukaryotes such as protists, and particularly ciliates, that enables adaptation to unfavorable environmental conditions. The formation of resting cysts involves large scale morphological and physiological changes that provide tolerance of extreme environmental stresses.

Rest Myocardial Perfusion Scintigraphy Showing the Invasion of the Hydatid Cyst in the Myocardium

Clinical Nuclear Medicine, 2013
A cardiac hydatid cyst is a rare complication of the Echinococcus infection, and it is seen in just 0.5% to 2% of all cases. Because it can cause sudden death, removing the cyst is recommended. It is important to determinate the relationship between the cyst and the intra/extracardiac structures before the operation because it is of vital importance ...

Presence of a tubulin pool in the resting cyst of the hypotrich ciliate, Histriculus muscorum

Cell Biology International Reports, 1985
Although microtubular organelles have not been observed in the resting cyst of the ciliate, Histriculus muscorum, the cyst was immunocytochemically stained with anti-tubulin antiserum, and one of its polypeptide bands reacted to the same antiserum after the immunoblotting test. Both these findings demonstrate the presence of tubulin in the resting cyst.
