Specification of the Okadaic Acid Equivalent for Okadaic Acid, Dinophysistoxin-1, and Dinophysistoxin-2 Based on Protein Phosphatase 2A Inhibition and Cytotoxicity Assays Using Neuro 2A Cell Line

Journal of Marine Science and Engineering, 2021
Diarrhetic shellfish poisoning (DSP) is a globally occurring disease threatening public health and trade. The causative toxins, okadaic acid (OA), dinophysistoxin-1 (DTX1), and dinophysistoxin-2 (DTX2) are collectively called OAs, and are quantified ...

Mass Spectral Characterisation of Three New Groups of Algal Toxins [PDF]

, 2009
This thesis reports the mass spectral identification and characterisation of three new groups of algal compounds. A series of novel pectenotoxins (PTXs) were identified in retained sub-samples of Irish mussel extracts that had previously been utilised ...

Detection of Dinophysis species and associated okadaic acid in farmed shellfish: a two-year study from the western Mediterranean area

Journal of Veterinary Research, 2018
Diarrhoetic shellfish poisoning (DSP), an alimentary intoxication known to lead to intestinal symptoms, and caused by toxins produced by some dinoflagellates (including several Dinophysis), represents a serious threat to public health.

Ginsenoside Rh1 Attenuates Alzheimer's Disease‐Like Deficits by Modulating Oxidative Stress and Mitochondrial Dysfunction via SIRT1‐Related Signaling

Phytotherapy Research, EarlyView.
Rh1 attenuates oxidative stress and mitochondrial dysfunction through SIRT1‐related signaling. ABSTRACT Alzheimer's disease (AD) remains a progressive neurodegenerative disorder with limited therapeutic options. Ginsenoside Rh1 has been reported to possess neuroprotective properties, yet its specific role and underlying mechanisms in AD are not fully ...

Electrochemical aptasensors for ultrasensitive multiplexed detection: Towards a new era of precision diagnostics and environmental monitoring

VIEW, EarlyView.
Electrochemical aptasensors are emerging as powerful platforms for precision diagnostics and environmental monitoring, owing to their high selectivity, programmability and compatibility with miniaturised systems. However, their broader application is constrained by limited signal intensity and challenges in reliable multiplexed detection.

Multifunctional Gold Nanocluster‐Based PROTAC System for Targeted Degradation of Phosphorylated Tau and Modulation of Neuroinflammation in Alzheimer's Disease

Advanced Functional Materials, Volume 36, Issue 52, 29 June 2026.
We present a novel proteolysis‐targeting chimera (PROTAC) system conjugated to lipoic acid gold nanoclusters (PLANC), designed to degrade pTau, regulate inflammatory signaling, and effectively traverse the blood‐brain barrier (BBB). PLANC degraded pTau at various phosphorylation sites, with mechanistic studies confirming proteasome‐mediated degradation
