Methodology for quantitative determination of the carbohydrate composition of brown seaweeds (Laminariaceae) [PDF]

open access: yesRSC Advances, 2014
The monosaccharide composition of four different samples of brown seaweeds Laminaria digitata and Saccharina latissima were compared by different high performance anion exchange chromatography (HPAEC) methods after different acid hydrolysis treatments or

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...

Alginic Acid-acetate [PDF]

open access: yesNature, 1946
VARIOUS attempts have been described1 to acetylate alginic acid by means of acetic anhydride or acetic acid, without or with catalysts, for example, pyridine, acids, etc. Some of the products thus obtained were probably degraded, and it appeared of interest, therefore, to find out whether the acetylation of alginic acid can be done by a relatively mild

Development and pharmaceutical performance of a novel co-processed excipient of alginic acid and microcrystalline cellulose

open access: yes, 2021
In this study, a co-processed excipient (Cop AA-MCC) was prepared from alginic acid (AA) and microcrystalline cellulose (MCC101) using a laboratory scale high-shear granulator. The obtained granules were compared to the primary materials (AA, MCC101), to

Alginic acid and hyaluronic acid, effective stabilizers of carthamin red colour in aqueous solutions

open access: yesActa Societatis Botanicorum Poloniae, 2014
Sodium salts and free forms of two heterosaccharides, alginic and hyaluronic acids were mixed with carthamin in a buffer at pH 5.5 and their preservation effects of carthamin red colour were screened after incubation for 24 h at 3-5oC in the dark.

Living Biohybrid Hydrogels for Co-Delivery of Oxygen, Anti-Cancer Drugs, and Probiotics: Effects on Cancer and Healthy Cell Viability. [PDF]

open access: yesMacromol Biosci
A probiotic‐enriched BioHybrid hydrogel that provides sustained O2, probiotic metabolites, and pH‐responsive anti‐cancer drug is reported. This BioHybrid hydrogel promotes healthy cell viability while reducing ROS and decreases cancer cell viability while increasing ROS under hypoxia conditions. The co‐administration of O2, metabolites, and drug from a
