Bysmatrum granulosum sp. nov., a new benthic dinoflagellate from the southwestern Indian Ocean [PDF]

open access: yes, 2001
A new benthic marine dino¯agellate, Bysmatrum granulosum Ten-Hage, Turquet, Quod & Couté, sp. nov., was obtained from sediment and coral samples from sites of La Réunion Island (SW Indian Ocean). This new species is described and illustrated by light and

Screening for Okadaic Acid by Immunoassay

open access: yesJournal of AOAC INTERNATIONAL, 1995
Abstract Increasing incidences of phytoplankton blooms with the potential danger of toxin release into the food chain have necessitated the search for new diagnostic methods that can detect toxins quickly and reliably. A competitive enzymelinked immunosorbent assay (ELISA) was developed to quantitate okadaic acid in shellfish and ...

Novel regulation of PKC-induced inflammation by Akt and protein phosphatase 2A in ovarian granulosa cells

open access: yesChinese Journal of Physiology, 2020
PKC-mediated inflammation is important in ovarian physiology. The roles of Akt and protein phosphatase 2A (PP2A) in PKC-mediated inflammation in ovarian granulosa cells (GCs) remain mostly unclear.

Comparison of neurons derived from mouse P19, rat PC12 and human SH-SY5Y cells in the assessment of chemical- and toxin-induced neurotoxicity

open access: yesBMC Pharmacology and Toxicology, 2017
Background Exposure to chemicals might be toxic to the developing brain. There is a need for simple and robust in vitro cellular models for evaluation of chemical-induced neurotoxicity as a complement to traditional studies on animals.

ER localized bestrophin1 activates Ca2+ dependent ion channels TMEM16A and SK4 [PDF]

open access: yes, 2009
Bestrophins form Ca2+ activated Cl- channels and regulate intercellular Ca2+ signaling1. We demonstrate that bestrophin 1 is localized in the endoplasmic reticulum (ER), where it physically interacts with stromal interacting molecule 1 (Stim1), the ER ...

Posttranslational modifications of GLUT4 affect its subcellular localization and translocation [PDF]

open access: yes, 2013
The facilitative glucose transporter type 4 (GLUT4) is expressed in adipose and muscle and plays a vital role in whole body glucose homeostasis. In the absence of insulin, only ~1% of cellular GLUT4 is present at the plasma membrane, with the vast ...

Determination of Lipophilic Marine Biotoxins in Mussels Harvested from the Adriatic Sea by LC-MS/MS

open access: yesFrontiers in Microbiology, 2018
Lipophilic marine biotoxins include okadaic acid, pectenotoxin, yessotoxin and azaspiracid groups. The consumption of contaminated molluscs can lead to acute food poisoning syndromes depending on the exposure level.

Dinophysis Toxins: Distribution, Fate in Shellfish and Impacts

open access: yesToxins, 2019
Several planktonic dinoflagellate species of the genus Dinophysis produce one or two groups of lipophilic toxins: (i) okadaic acid (OA) and its derivatives, the dinophysistoxins (DTXs), and (ii) pectenotoxins (PTXs) [...]
