Biosorption is a process in which solids of natural origin are employed for binding heavy metals. It is a promising alternative method to treat industrial effluents, mainly because of its low cost and high metal binding capacity. In this work, the mercury and iron biosorption process by Sargassum sp. seaweed biomass was studied. The work considered the parameters of mercury and iron sorption su...

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...

Abstract Even though seaweeds have been considered a nutrient-rich dietary source of minerals in other parts the world, there is little knowledge about trace element accumulation Arabian Gulf. The Gulf particular interest due to being an extreme environment, as it features some highest temperatures and salinities observed any marine waters world. This study determined contents using inductively...

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...

ETHNOPHARMACOLOGICAL RELEVANCE Sargassum polycystum, a type of brown seaweed, has been used for the treatment of skin-related disorders in traditional medicine. AIM OF THE STUDY The aim of the present study is to investigate the antimelanogenesis effect of Sargassum polycystum extracts by cell-free mushroom tyrosinase assay followed by cell viability assay, cellular tyrosinase assay and melan...
