BACKGROUND Carrageenan is a sulfated polysaccharide that exists in red seaweeds recently shown to have anticancer properties. Previous findings show various effects of carrageenan suppressing tumor cell growth. One of the hallmarks of cancer is uncontrolled proliferation, a consequence of loss of normal cell-cycle control, that underlies tumor growth. Recently there is an increasing interest in...

Knowledge about the marine malacofauna in the Magellan Region has been gained from many scientific expeditions that were carried out during the 19th century. However, despite the information that exists about molluscs in the Magellan Region, there is a lack of studies about assemblages of molluscs co-occurring with macroalgae, especially commercially exploitable algae such as Gigartina skottsbe...

ι-Carrageenases belong to family 82 of glycoside hydrolases that degrade sulfated galactans in the red algae known as ι-carrageenans. The catalytic mechanism and some substrate-binding residues of family GH82 have been studied but the substrate recognition and binding mechanism of this family have not been fully elucidated. We report here the purification, cloning and characterization of a new ...

Abstract Background Salmonella belongs to the Enterobacteriaceae family, a gram-negative, non-spore-forming, rod-shaped, motile, and pathogenic bacteria that transmit through unhygienic conditions. It is estimated 21 million new infections arise every year, resulting in approximately 200,000 deaths. more prevalent among children, old aged, immunocompromised individuals. The frequent usage of cl...

Intercellular communication via gap junctions, as measured by dye and electrical coupling, disappears within 12 h in primary rat hepatocytes cultured in serum-supplemented media or within 24 h in cells in a serum-free, hormonally defined medium (HDM) designed for hepatocytes. Glucagon and linoleic acid/BSA were the primary factors in the HDM responsible for the extended life span of the electri...

Fish Protein Gels HPP can be used to produce new surimi products. In surimi processing, the sarcoplasmic proteins are removed by thorough washing since they do not form gels when heated. However, if sarcoplasmic proteins are pressurized at over 300 MPa, they will coagulate and can be incorporated into surimi and related products. Pressure-induced gels have been reported to have a springy textur...

(2015) Are multifunctional marine polysaccharides a myth or reality? Front. Chem. 3:39. Marine algae are ancient photosynthetic organisms that constitute the largest group in the plant kingdom. They are used for functional food, cosmetic additives, supplements productions, and in traditional medicine due to taste, prophylactic, and therapeutic effects. Algae contain microelements and iodine-con...

Niklas (2000) defined plants as “photosynthetic eukaryotes,” thereby including brown, red, and green macroalgae and microalgae. These groups share several features, including the presence of a complex, dynamic, and polysaccharide-rich cell wall. Cell walls in eukaryotes are thought to have evolved by lateral transfer from cell wall-producing organisms (Niklas, 2004). Green and red algae origina...
