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...

BACKGROUND AND OBJECTIVES Leishmaniasis is a protozoan parasitic disease which is transmitted by the female Phlebotomus sand fly and is prevalent in four continents.The first-choice treatment for the leishmaniasis is pentavalent antimonials, which are potentially toxic and often ineffective and use of them exhibit therapeutic failure. These pharmaceutical problems point towards the need to deve...

Stable isotope ratios of carbon (delta13C) and nitrogen (delta15N) were used to investigate feeding patterns of larval and early juvenile pelagic fishes in slope waters of the Gulf of Mexico. Contribution of organic matter supplied to fishes and trophic position within this pelagic food web was estimated in 2007 and 2008 by comparing dietary signatures of the two main producers in this ecosyste...
