Petit-spot volcanism plays a critical role in the metasomatism of oceanic plates prior to subduction and in their recycling into the deep mantle. The extent of metasomatism depends on the number and volume of petit-spot volcanic edifices and intrusions, making precise identification of petit-spot volcanic fields essential. However, conventional methods based on seafloor topography and acoustic backscatter intensity alone have limitations in accurately delineating these features.

Unlabelled: Microbial degradation of methylphosphonate (MPn) is an important pathway contributing to the 'methane paradox' in the oxic ocean. spp. are suggested to participate in this process.

Background: The association observed between mental stress and metabolic syndrome (MetS) has varied across studies and may be confounded by physical activity (PA) and fitness status.
Method: This study included a military cohort of 2,854 participants in Taiwan who were not taking any medications and were free of baseline MetS. The Brief Symptoms Rating Scale (BSRS-5) includes five domains-depression, anxiety, hostility, insomnia, and interpersonal sensitivity-measured on a five-point Likert-type scale ranging from 0 to 4, with a maximum score of 20.

Tetrodotoxin (TTX), the pufferfish toxin, has the potential to cause fatal food poisoning because of its potent voltage-gated sodium channel (Na) blocking activity. 4-epiTTX, 11-norTTX-6(S)-ol, and 11-oxoTTX are the major TTX analogues found in marine animals; thus, their chemical properties and biological activities should be determined. In this study, these three TTX analogues were purified to a high level (purity >97%) from pufferfish and newts.
