The physiology of dormancy and germination in cysts of the marine dinoflagellate Scrippsiella trochoidea
Cysts of Scrippsiella trochoidea are representative of the thick-walled non-motile resting cells produced by many dinoflagellates. Although the influence of cysts on the biology and ecology of dinoflagellates may be significant, little is known of the factors controlling cyst dormancy and …

Studies on the cell wall of dinoflagellate resting cysts : morphological development, ultrastructure, and chemical composition
… These cell walls, along with those of resting cysts formed by many other dinoflagellate species, are resistant to degradation and persist in the depositional environment. Selective preservation of these materials has created a rich dinoflagellate fossil record (extending back ~225 million …

Histological characterization of CT-identified osteoarthritic subchondral cysts and co-registration of CT with MRI
… the histologic nature of subchondral cysts identified by micro computed tomography (μCT) which had been registered with MRI images in which marrow lesions were identified. Femoral heads were collected from 10 patients (6 females and 4 females; age 29-80) who underwent total hip …

Clinical Characteristics of the Pediatric Patients with Pre-natally and Post-natally Diagnosed Choledochal Cysts
The choledochal cysts have been known as the ductal dilatation caused by an anomalous pancreaticobiliary duct union(APBDU). Recently by the help of the diagnostic techniques, choledochal cysts have been much more reported in the prenatal period. The pre-natally diagnosed choledochal cysts were …

Development of an automated system for extraction and quantification of soybean cyst nematode (SCN) eggs and cysts
Soybean is the world’s foremost source of vegetable protein and oil. In order to meet the growing global soybean demand for feed and biodiesel, soybean production in the US will need to increase by 28 percent over the next decade. Addressing this demand necessitates increasing efficiency of soybean …

Dinoflagellate cysts of the Gymnodiniaceae, Peridiniaceae, and Gonyaulacaceae from the Upper Cretaceous Monmouth Group, Atlantic Highlands, New Jersey
… and biostratigraphy of fossil dinoflagellate cysts belonging to three families (Gymnodiniaceae, Peridiniaceae, and Gonyaulacaceae) are investigated from the Campanian-Maestrichtian Mount Laurel Sand, Navesink Fonnation, and Sandy Hook Member of the Red Bank Sand of Atlantic Highlands, New …

Paleoceanography across the Pliocene–Pleistocene transition in the southern Bering Sea: dinoflagellate cysts and acritarchs from IODP Site U1341
… Pacific has been analyzed for dinoflagellate cysts, acritarchs and other palynomorphs. Based on 86 samples, with a spacing equivalent to between 500 and 6000 years, this is the most stratigraphically detailed late Cenozoic marine palynological study yet undertaken in the Bering Sea. The …

Evaluation of Two Techniques of Cancellous Bone Grafting of Experimental Subchondral Bone Cysts in the Medial Femoral Condyles of Horses
… to mimic clinical cases of subchondral bone cysts after debridement. The defects were created with either a standard square ended drill bit or a compaction drill bit. The compaction drill bit compresses bone laterally and distally creating a dense wall and floor. Twelve-mm sternal cancellous …

THE FREQUENCY-DEPENDENCE OF THE NMR LONGITUDINAL RELAXATION RATE, T(1)(-1), OF WATER IN CYSTS OF THE BRINE SHRIMP (ARTEMIA)
… and is also observed in this study for Artemia cysts between 10 and 500 MHz. At lower Larmor frequencies, below 1 MHz, the relaxation rates of water in brine shrimp cysts are influenced by additional relexation mechanisms; translational diffusion of hydration water is one possibility.

Giardia in New Zealand animals : prevalence, viability in the environment and preservation : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Microbiology at Massey University
… has been focused on the occurrence of Giardia cysts in the water ways of this country and in particular in municipal water supplies. Little is known about the occurrence of asymptomatic or even symptomatic giardiasis in people as this is not a notifiable disease, even less is known about …

Western Pacific paleoceanography across the Early–Middle Pleistocene boundary (~773 ka, Marine Isotope Stage 19): Dinoflagellate cysts of the Chiba composite section, Japan.
… of MIS 19c. Abundant warm-water autotrophic dinocysts during MIS 19c reflects warm conditions and a northward shift of the warm Kuroshio current from 786 to 773 ka. The end of MIS 19c is marked by a sharp decrease in species richness and evenness, an abrupt and sustained rise to dominance of …

Tracing hydrological millennial-scale cycles in the late Quaternary of the Cariaco Basin and the southern Gulf of Cádiz using coccoliths and dinoflagellate cysts
… demonstrates that coccoliths and dinoflagellate cysts are very useful as paleoclimatological indicators for the elucidation or a better understanding of the late Quaternary regional and global palaeoclimate. This study also reveals new insights in coccolithophore and dinoflagellate palaeoecology. …

Zytokeratinmuster zur Unterscheidung von odontogenen Zysten
The clinical outcome of treatment of odontogenic cysts differs depending on separate entities. Particular clinical relevance must be attached to the distinction between odontogenic keratocysts, which have an evident tendency to recur, and other odontogenic cysts. The aim of this study was to …

Methods of testing for giardia in water : a thesis presented in partial fulfilment of the requirements for the degree Master of Science in Microbiology at Massey University
… for testing large volumes of water for Giardia cysts, this was adapted into the 16th edition of the Standard Methods. To test the method cultured cysts were required for spiked trials. A published method of encystation by Schupp et al (1988) was investigated as a potential source of cysts. …

The chemical ecology of Lingulodinium polyedra and its microbiome
… environmental conditions, L. polyedra will form cysts that optimize its defense and survivorship. Prior evidence shows that sterilized cysts of dinoflagellates, including L. polyedra, do not germinate well and have low post-excystment survivorship, but cells can recover when bacteria are added. …
