Abstract (sommario):

The relationship between molecular structure and bioactivity was evaluated for sodium alginates obtained under different degradation treatment (raw alginates, heat-treated, and chemical-treated) from Sargassum sp. This study was conducted to identify the antioxidant activities of the degraded sodium alginate from Sargassum sp. compared to raw extract. Raw alginate as the control treatment was dried overnight at 60 °C, while heat-treated was heated raw alginate at 140oC in a laboratory oven (4.5 hours). Two chemical-treated were applied. Raw alginate added hydrogen peroxide and raw alginat with

Abstract (sommario):

Biopolymeric nanoparticulate systems hold favorable carrier properties for active delivery. The enhancement in the research interest in alginate formulations in biomedical and pharmaceutical research, owing to its biodegradable, biocompatible, and bioadhesive characteristics, reiterates its future use as an efficient drug delivery matrix. Alginates, obtained from natural sources, are the colloidal polysaccharide group, which are water-soluble, non-toxic, and non-irritant. These are linear copolymeric blocks of α-(1→4)-linked l-guluronic acid (G) and β-(1→4)-linked d-mannuronic acid (M) residue

Abstract (sommario):

This review aims to gather the current state of the art on the encapsulation methods using alginate as the main polymeric material in order to produce hydrogels ranging from the microscopic to macroscopic sizes. The use of alginates as an encapsulation material is of growing interest, as it is fully bio-based, bio-compatible and bio-degradable. The field of application of alginate encapsulation is also extremely broad, and there is no doubt it will become even broader in the near future considering the societal demand for sustainable materials in technological applications.

Abstract: Irreversible hydrocolloid impression materials or alginate is commonly used in dental practice. Its setting time range is 1–4.5 minutes. The setting time is affected by several factors such as water temperature mixed with the alginate powder. There are previous studies evaluated the effect of water temperature on the alginate’s setting time, however, the collected data is still minimal. Therefore, this study aimed to evaluate the effect of water temperature on alginate’s setting time on larger scale. There were total of 423 samples divided into three groups: cold, moderate, and warm

Abstract. This research aims to modify sodium alginate using the periodate oxidation method. The alginate used is not easily biodegradable, so oxidation is carried out with sodium metaperiodate to facilitate biodegradation and produce new functional groups. With the presence of new functional groups in alginate, hydrogels can be formed using type B gelatin and BaCl2. Alginate was successfully synthesized because an oxidation degree of 3% was obtained and the Fourier Transform Infra Red Attenuated Total Reflectance (FTIR-ATR) results showed a band of 1720 cm-1 which indicated a change in algina

Abstract (sommario):

Marine alginates are well established in wound management. Compared with different modern wound dressings, marine alginates cannot prove superior effects on wound healing. Alginates from bacteria have never been studied for medical applications so far, although the microbial polymer raises expectations for improved binding of wound factors because of its unique O-acetylation. Due to its possible positive effects on wound healing, alginates from bacteria might be a superior future medical product for clinical use.

Abstract (sommario):

Alginate is a popular candidate for encapsulation of cells due to the formation of gels with divalent ions under physiological conditions. Stable alginate gels can be formed by the selection of alginates with a high content of guluronic acid (G) and gelling in a mixture of calcium and barium. These alginate gels have been proposed as immune protective barriers for the transplantation of human pancreatic islets (insulin producing cells) for the treatment of type 1 diabetes where the alginate gel protects the transplant from the host immune system. Microencapsulation can thus provide a way to ov

Mucus is a hydrogel that covers epithelial cells and acts as an intermediary between the exterior and interior surfaces of the human body. It is complex and diverse, comprised of various compounds and serves as a selective barrier to pathogens, nutrients and administered substances. It is therefore important to circumvent or penetrate this barrier to increase drug bioavailability. The most important constituent of mucus is mucin glycoprotein that enables gel formation. Due to the molecular nature of mucin, it interacts with most substances including polyanionic biopolymers like alginates. Algi

Abstract (sommario):

The overall objective of this study was to develop, optimize and evaluate novel formulations, which reduce herbicide leaching and enhance agronomic efficacy. Numerous studies have demonstrated that CsT promotes environmental quality and enhances sustainable crop production, yet continued use of CsT-practices appears threatened unless cost effective alternative weed control practices can be found. The problem is pressing in the southern portion of the Atlantic Coastal Plain region of the eastern USA where cotton and peanut are produced extensively. This research addressed needs of the region’s

Abstract (sommario):

A drug-loaded conductive polymer/hydrogel blend, benzoic acid-loaded poly(3,4-ethylenedioxythiophene/alginate (BA-loaded PEDOT/Alg) hydrogel, was used as a carrier/matrix for an electrical stimuli transdermal drug delivery system (TDDS). The effects of crosslinking ratio, PEDOT particle size, and electric field strength on the release mechanism and the diffusion coefficient (D) of BA were examined by using a modified Franz-diffusion cell. The diffusion scaling exponent value of BA is close to 0.5 which refers to the diffusion controlled mechanism, or the Fickian diffusion as the BA release mec

Abstract (sommario):

The major bottlenecks in rearing the highly priced gastropod abalone (Haliotis spp.) are the slow growth rate and the high mortality during the first 8 to 12 weeks following metamorphosis and settling. The most likely reason flor these problems is related to nutritional deficiencies in the diatom diet on which the post larvae (PL) feed almost exclusively in captivity. Higher survival and improved growth rate will reduce the considerable expense of hatchery-nursery resisdence time and thereflore the production costs.

Abstract (sommario):

The production of a renewable energy from biomass, such as ethanol by fermentation, has received special attention as a consequence of the world energy crisis. Nowadays, gasohol E-10, a mixture of 10% ethanol and 90% gasoline has been widely used in vehicles in Thailand and there is an attempt to promote the use of E-20 or E-85 in the vehicles in the near future. Ethanol fermentation by conventional batch suffers from various constrains such as, low cell density and rather time consuming. Although continuous fermentation by suspended cell culture can be used to speed up the process, it is more

Abstract (sommario):

Background. In this proposal we suggest developing a common solution for three seemingly unrelated acute problems: (1) improving sustainability of fast-growing mushroom industry producing worldwide millions of tons of underutilized leftovers; (2) alleviating the epidemic of vitamin D deficiency adversely affecting the public health in both countries and in other regions; (3) reducing spoilage of perishable fruit and vegetable products leading to food wastage. Based on our previous experience we propose utilizing appropriately processed mushroom byproducts as a source of two valuable bioactive
