To assess distributional shifts of species in response to recent warming, historical distribution records are the most requisite information. The surface seawater temperature (SST) of Kochi Prefecture, southwestern Japan on the western North Pacific, has significantly risen, being warmed by the Kuroshio Current. Past distributional records of subtidal canopy-forming seaweeds (Laminariales and F...

Two of bioactive natural products were founded in a brown alga, Sargassum fulvellum. After isolation and purification, the molecular structures of these two products were investigated by NMR spectroscopy and GC-mass spectroscopy. The two compounds were identified to be 1-O-palmitoyl-2-O-oleoyl-3-O-(alpha-D-glucopyranosyl)-glycerol (POGG) and 1-O-myristoyl-2-O-oleoyl-3-O-(alpha-D-glucopyranosyl)...

The purified total sterols and β-sitosterol extracted from Sargassum horneri were evaluated for their antidepressant-like activity using the forced swim test (FST) and tail suspension test (TST) in mice. Total sterols and β-sitosterol significantly reduced the immobility time in the FST and TST. Total sterols were administered orally for 7 days at doses of 50, 100, and 200 mg/kg, and β-sitoster...

Seaweed extracts of Sargassum cinereum was used as a reducing agent in the eco-friendly extracellular synthesis of silver nanoparticles from an aqueous solution of silver nitrate (AgNO3). High conversion of silver ions to silver nanoparticles was achieved with a reaction temperature of 100(°) and a seaweed extract concentration of 10% with a residential time of 3 h. Formation of silver nanopart...

With fossil fuels being the primary source of energy in today’s world, different types biofuels and bioenergy have been proposed to reduce our reliance on them.<b> </b>In recent years, Mexico has suffering from overaccumulation macroalgae species known as <i>Sargassum</i> its Caribbean coastal shoreline. The purpose this study is investigate usage Sargassum feedstock for...

Background: Studies have shown that abdominal adhesions occur due to an oxidative stress by ROS. Sargassum sp. extract contains many antioxidative compounds that might be utilized to interrupt this process. This study intends to study the efficacy of Sargassum sp. extract on preventing abdominal adhesions. Methods: In this study, 20 female rats were divided into two groups. Group 1 receive Sarg...
