The marine environment represents a relatively untapped source of functional ingredients that can be applied to various aspects of food processing, storage, and fortification. Moreover, numerous marine-based compounds have been identified as having diverse biological activities, with some reported to interfere with the pathogenesis of diseases. Bioactive peptides isolated from fish protein hydr...

Sargassum Vulgare was collected from the Red sea coastlines, Al-Hodeida, Yemen, and dried. The dried powder subjected to consecutive extraction by methanol. methanol extract solvent fractionation (n-hexane-chloroform-ethyl acetate n-butanol solvents). vulgare polysaccharides (S.R1P, S.R1M, S.R5s, S.R5ss) were isolated precipitation with [19] n-hexane fraction evaluated phytochemically. physicoc...

The unique attributes, biodegradability, biocompatibility, perfect accessibility, and low production costs led to the use of natural gums in a different section our lives. Among them, we can mention obtained from microorganisms (xanthan gum gellan gum), plant tissues (Arabic tragacanth), seeds (konjac guar seaweeds (alginates, agar gum, carrageenans). Gums have essential applications medical ph...

Gastroesophageal reflux disease is mediated principally by acid. Today, we recognise reflux reaches beyond the esophagus, where pepsin, not acid, causes damage. Extraesophageal reflux occurs both as liquid and probably aerosol, the latter with a further reach. Pepsin is stable up to pH 7 and regains activity after reacidification. The enzyme adheres to laryngeal cells, depletes its defences, an...

Starch-degrading enzymes glucoamylase (from Aspergillus niger), and pullulanase (from Bacillus acidopullulyticus) were purified using alginates (polysaccharides consisting of mannuronic acids and guluronic acids) by a recently developed technique called macroaffinity ligand-facilitated three-phase partitioning (MLFTPP). In this process, a crude preparation of the enzyme was mixed with alginate....

The change in rheological and mechanical properties for some ionotropic cross-linked metal-alginate hydrogel complexes in particularly copper-alginate membranes in the presence of some organic solvents (benzene, toluene, xylene, carbon tetrachloride, acetone, chloroform, dichloroethane, isobutyl alcohol and ethyl alcohol) or buffer solutions (acetates, borates and universal buffers) have been i...

A significant percentage of patients with gastroesophageal reflux disease (GERD) will not respond to proton pump inhibitor (PPI) therapy. The causes of PPI-refractory GERD are numerous and diverse, and include adherence, persistent acid, functional disorders, nonacid reflux, and PPI bioavailability. The evaluation should start with a symptom assessment and may progress to imaging, endoscopy, an...

In this paper, different formulation types of microparticulate systems such as beads, microbeads, microspheres and microsponges using to special attention chitosan, alginate and eudragit RS 100 are reviewed. Chitosan and alginates are natural, anionic or cationic, biocompatible, biodegredable and non-toxic polymers. They have excellent potential for pharmaceutical and biopharmaceutical applicat...
