The production, molecular weight and viscosifying power of alginate produced by Azotobacter vinelandii is affected by the carbon source in submerged cultures
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-11-01)
Alginate is a linear polymer composed of b-1,4 linked mannuronic acid and its epimer, a-L-guluronic acid, and frequently extracted from marine algae, as from bacteria such as Azotobacter and Pseudomonas. Here, we show the ...
New alginic acid-atenolol microparticles for inhalatory drug targeting
(Elsevier Science, 2014-04)
The inhalatory route allows drug delivery for local or systemic treatments in a noninvasively way. The current tendency of inhalable systems is oriented to dry powder inhalers due to their advantages in terms of stability ...
Synthesis, characterization and cytotoxicity of S-nitrosomercaptosuccinic acid-containing alginate/chitosan nanoparticles
(Iop Publishing Ltd, 2017)
Nitric oxide (NO) is an endogenous free radical, which plays key roles in several biological processes including vasodilation, neurotransmission, inhibition of platelet adhesion, cytotoxicity against pathogens, wound ...
Seasonal variation on size and chemical constituents of Sargassum sinicola Setchell et Gardner from Bahia de La Paz, Baja Califoria Sur, Mexico
(Phycological Research, 2008)
Investigation on seasonal variation in size and chemical constituents of Sargassum sinicola Setchell et Gardner from Bahía de La Paz, Baja California Sur, Mexico, was carried out from a control bed and compared with an ...
The Addition of Propylene Glycol Alginate to a Fluoride Solution to Control Enamel Wear: An in situ Study
(2020-12-01)
The aim of this study was to evaluate the protective effect of propylene glycol alginate (PGA) associated with sodium fluoride (NaF) against enamel erosion and erosion-abrasion. A 4-phase, split-mouth, double-blind, crossover ...
The effect of chitosan as internal or external coating on the 5-ASA release from calcium alginate microparticles
(2010)
The effect of chitosan as internal or external coating on the mesalamine (5-ASA) release from calcium alginate microparticles (CaAl) was studied, and a delayed release of 5-ASA system intended for colonic drug delivery was ...
