Molecular Mechanism of Mulberrin Regulating Lipid Metabolism Homeostasis Based on the Gut–Liver Axis Fiaf/AMPK Signaling Pathway

Food Frontiers, Volume 7, Issue 2, March 2026.
The molecular mechanism for mulberrin regulating lipid metabolism homeostasis. ABSTRACT Lipid metabolism disorders and the induced metabolic diseases have risen to become one of the primary public health issues. Our preliminary experimental results confirmed that mulberry leaf flavonoid extract exhibited efficacy in lipid metabolism regulation; the ...

The Acute Toxicity of Tetrodotoxin and Tetrodotoxin–Saxitoxin Mixtures to Mice by Various Routes of Administration

Toxins, 2018
Tetrodotoxin (TTX) is a potent neurotoxin associated with human poisonings through the consumption of pufferfish. More recently, TTX has been identified in bivalve molluscs from diverse geographical environments, including Europe, and is therefore ...

eDNA Metabarcoding Reveals Microbial Community Composition in Tropical Mangrove Forests in Makassar, Indonesia

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This study used environmental DNA (eDNA) metabarcoding with 18S rRNA markers to assess microbial diversity in the Lantebung Mangrove Forest, Makassar, Indonesia. It identified 103 microbial species across five kingdoms, revealing higher species richness in open‐water areas (P1) and greater individual abundance under mangrove canopy (P2).

An Overview on the Marine Neurotoxin, Saxitoxin: Genetics, Molecular Targets, Methods of Detection and Ecological Functions

Marine Drugs, 2013
Marine neurotoxins are natural products produced by phytoplankton and select species of invertebrates and fish. These compounds interact with voltage-gated sodium, potassium and calcium channels and modulate the flux of these ions into various cell types.

Microcystis Sp. Co-Producing Microcystin and Saxitoxin from Songkhla Lake Basin, Thailand

Toxins, 2021
The Songkhla Lake Basin (SLB) located in Southern Thailand, has been increasingly polluted by urban and industrial wastewater, while the lake water has been intensively used. Here, we aimed to investigate cyanobacteria and cyanotoxins in the SLB.

Presynaptic initiation by action potentials of retrograde signals in developing neurons. [PDF]

, 1997
Until recently, the only means by which electrical activity was believed to initiate retrograde signals was via postsynaptic events: modulated synthesis or release of trophic factors.

Cyanobacteria and Cyanotoxins in Mediterranean Reservoirs: Ecological Variability, Risks and Implications for Water Quality Assessment

Ecohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT The increasing demand for freshwater, in combination with climate change and pollution, compromises the quality and quantity of water resources. These pressures have intensified cyanobacterial blooms, including toxic events that threaten human health and aquatic ecosystems. This study complements the objectives of the Water Framework Directive
