Platelet-rich plasma (PRP) may have the potential to enhance articular cartilage regeneration through release of growth factors including transforming growth factor isoforms. The purpose of this study was to investigate the potential for PRP to stimulate chondrogenic differentiation in three-dimensional PRP hydrogel constructs. Allogenic PRP was prepared using a double centrifugation protocol w...

Alginate is an edible heteropolysaccharide that abundantly available in the brown seaweed and capsule of bacteria such as Azotobacter sp. Pseudomonas Owing to alginate gel forming capability, it widely used food, textile paper industries; a lesser extent biomedical applications biomaterial promote wound healing tissue regeneration. This evident from rising use alginate-based dressing for heavil...

In this study, we report the preparation of a novel microcapsule of ~ 100 μm with a liquid (as compared to solid-like alginate hydrogel) core and an alginate-chitosan-alginate (ACA) shell for encapsulation and culture of embryonic stem (ES) cells in the miniaturized 3D space of the liquid core. Murine R1 ES cells cultured in the microcapsules were found to survive (> 90%) well and proliferate t...

The purpose of our study was to achieve the gastro-retentive delivery Clarithromycin by producing floating pellets get a better therapeutic effect against gastrointestinal ulcers mostly caused Hedyotis pylori. Thereby were prepared utilizing blending polymers such as Sodium (Na) Alginate and Hydroxy Propyl Methyl Cellulose (HPMCK4M & HPMC K100LV). HPMC-alginate blend containing produced hyd...

The process of electrostatic extrusion as a method for cell immobilization was investigated that could be used for potential applications in medicine. An attempt was made to assess the effects of cell addition and polymer concentration on the overall entrapment procedure, ie, on each stage of immobilization: polymer-cell suspension rheological characteristics, electrostatic extrusion process, a...

Alginate hydrogels are versatile self-assembling biocompatible materials with diverse biomedical and food industrial applications, which includes uses in encapsulation, (drug) delivery tissue engineering. Hydrogel formation requires cross-linking, for alginates is often done calcium ions that engage specific interactions the polysaccharide carboxylic acid groups. Water molecules also hydrate th...

Abstract: Aim: Berberine hydrochloride is a Traditional Chinese Medicine component with antibacterial, antiviral, anti-inflammatory, antioxidant and lowering blood sugar effects. However, the application of berberine has been hindered for long time due to its poor solubility low bioavailability. This study aims design liposomes-gel enhance bioavailability activity hydrochloride. Materials Metho...

A microporous hydrogel was developed using sodium alginate (alg) and 4-aminosalicylic acid (4-ASA). The synthesized hydrogel was characterized using various analytical techniques such as Fourier transform infrared spectroscopy (FTIR), Carbon-13 nuclear magnetic resonance (13C-NMR), X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and differential scanning calorimetry (DSC). A...
