Alginates are polysaccharides used as food additives and encapsulation agents in biotechnology, and their functional properties depend on its molecular weight. In this study, different steady-states in continuous cultures of A. vinelandii were established to determine the effect of the dilution rate (D) and the agitation rate on alginate production and expression of genes involved in alginate p...

Requirements for successful cellular encapsulation are reviewed, with emphasis on the bioartificial pancreas. These requirements fall into three general categories: graft tissue viability, host response, and surgical practicality. Several design decisions, such as choice of materials, have ramifications on many requirements that must be simultaneously considered. Device dimensions are critical ...

BACKGROUND For children requiring split-thickness skin grafting for burn injury, the optimum donor site dressing is an ongoing subject of debate. The most common dressings in use, both regionally and worldwide, are calcium alginates. We will compare an alginate with two other dressings, all of which are in current use in the Pegg Leditschke Paediatric Burns Centre (PLPBC), to determine which dr...

Islets encapsulated in immunoprotective microcapsules are being proposed as an alternative for insulin therapy for treatment of type 1 diabetes. Many materials for producing microcapsules have been proposed but only alginate does currently qualify as ready for clinical application. However, many different alginate-based capsule systems do exist. A pitfall in the field is that these systems are ...

Heartburn and acid regurgitation are the cardinal symptoms of gastroesophageal reflux and occur commonly in the Canadian population. Multiple non-prescription treatment options are available for managing these symptoms, including antacids, alginates, histamine-H2 receptor antagonists (H2RAs), and proton-pump inhibitors (PPIs). As a result, pharmacists are ideally positioned to recommend appropr...
