Developing novel therapeutic agents for Acanthamoeba infection and investigating the process of encystment
… the use of biguanides alone. The findings of encystment investigation (the transformation of trophozoites into cysts) showed that the agonists in particular the β ultra-long against indacaterol stimulated the encystment and the antagonists β₁ metoprolol blocked the formation of cysts and …

The reciprocal influence of trematode parasites and malathion on developing pickerel frogs (Rana palustris)
… malathion as embryos suffered increased parasite encystment rates compared to controls. My research identifies embryonic development as a sensitive window and the potential for increased susceptibility to infection long after pesticide exposure has ceased. With potential for increased parasite …

Studies on Bucephalid cercaria including a new species from the Dillon Beach area
… and finally bore into a suitable site for encystment, losing their tails on the way (Woodhead, 1927). The metacercariae reach the definitive host when the smaller fish is devoured. It is not uncommon for the same species of fish to act as both second intermediate and definitive hosts.</p>

Survival potential of microalgae for long-term space missions
… pluvialis which can undergo the state of encystment and extremophilic algal species such as Dunaliella salina and cryophilic snow algae may be suitable species for long-term missions as they can produce high concentrations of antioxidants such as the red astaxanthin (keto-carotenoid) or …

Purification and characterization of TFIIIA from Acanthamoeba castellanii
… control. During the process of A. castellanii encystment, both ribosomal RNA (rRNA) and 5S RNA transcription are coordinated down-regulated. The loss of 5S RNA synthesis is associated with the disappearance of TFIIIA activity, and the loss of rRNA synthesis is caused by a modification of …

The Characterization of Circular Extrachromosomal rDNA Elements in Naegleria SPP
… propagation across several culture passages, encystment and excystment. N. gruberi trophozoites transfected with constructs that either have or do not have the putative ori demonstrated diminished propagation, indicating other components of the NRS may be necessary for replication. The …

Studies on the cell wall of dinoflagellate resting cysts : morphological development, ultrastructure, and chemical composition
This thesis presents a series of investigations on the specialized cell covering of a dormant stage (the resting cyst) in the life cycle of the marine dinoflagellate Lingulodinium polyedra. These cell walls, along with those of resting cysts formed by many other dinoflagellate species, are …

The physiology of dormancy and germination in cysts of the marine dinoflagellate Scrippsiella trochoidea
… activity just prior to excystment. Encystment and germination in S. trochoidea represent developmental patterns which are regulated by specific, albeit not yet well understood, environmental and biological parameters. The further elucidation of these processes and their regulation …

The Distribution and Biology of the Invasive Eyefluke of Waterfowl (Philophthalmus gralli) in Texas
… birds. The preference of water stargrass for encystment substrate by P. gralli cercariae indicates that many species of aquatic birds are at risk of infection. The infection dynamics are much more complicated than expected, and indicate that interactions between snail and parasite genotypes …

Augmented growth of haematococcus pluvialis using nutrients from post hydrothermal liquefaction wastewater (PHWW)
… of the chlorophyll: carotenoid ratio. After encystment, astaxanthin production was quantified using high performance liquid chromatography (HPLC), and these data showed that it was reduced by 47.3% and 34.1% in the 0.125% and 0.25% PHWW augmented cultures, respectively. Even though the amount …
