Application of a Quantitative PCR to Investigate the Distribution and Dynamics of Two Morphologically Similar Species, and (Dinophyceae) in Korean Coastal Waters.

Species of the marine dinoflagellate genus are known to produce various potent biotoxins and can form noxious blooms that cause mass mortalities of fish and shellfish. To date, harmful blooms of the species have been reported in Korea, but was recently recorded off the southern coast of Korea. Here, we developed a quantitative real-time PCR (qRT-PCR) assay with specific primer pairs for the accurate detection and quantification of these two similar-looking unarmored species, and and investigated their distribution and dynamics in Korean coastal waters.

Syndinean dinoflagellates of the genus Euduboscquella are paraphyletic.

Syndinean dinoflagellates of the genus Euduboscquella infect marine ciliates and dinoflagellates. Euduboscquella species infecting dinoflagellates are understudied relative to congeners infecting ciliates and their molecular phylogeny remains uncertain. Morphology, development, and rRNA gene sequences of intracellular parasites infecting heterotrophic dinoflagellates from coastal waters of Busan, Republic of Korea in summer to fall of 2019-2021 indicate that Cucumeridinium coeruleum, Gyrodinium cf.

Rylene Dye-Loaded Polymeric Nanoparticles for Photothermal Eradication of Harmful Dinoflagellates, and .

In the era of climate changes, harmful dinoflagellate outbreaks that produce potent algal toxins, odor, and water discoloration in aquatic environments have been increasingly reported. Thus, various treatments have been attempted for the mitigation and management of harmful blooms. Here, we report engineered nanoparticles that consist of two different types of rylene derivatives encapsulated in polymeric micelles.

Magnetic separation: a highly effective method for synchronization of cultured erythrocytic Plasmodium falciparum.

The magnetic method has been previously utilized to concentrate Plasmodium-infected erythrocytes without any significant influence on the viability of the parasite. We attempted, in this study, to concentrate and synchronize cultivated P. falciparum via the magnetic method.
