Obesity is a major epidemic that poses a worldwide threat to human health, as it is also associated with metabolic syndrome, type 2 diabetes and cardiovascular disease. Therapeutic intervention through weight loss drugs, accompanied by diet and exercise, is one of the options for the treatment and management of obesity. However, the only approved anti-obesity drug currently available in the mar...

Alginates are classed as a dietary fibre and have been shown to inhibit digestive enzymes in vitro, and therefore could be used as an obesity treatment. The current study aims to assess whether alginate in a bread vehicle maintains its inhibition properties despite cooking and digestion, and may therefore be used as a potential treatment for obesity. After 180 min in a model gut that replicates...

A number of polymers used in the production of carriers for drug delivery applications, possessing high surface area, appropriate surface chemistry and porosity, chemical stability and low cost have been investigated. One of these promising candidates are natural polysaccharides such as alginic acid sodium salt, guar gum, xanthan gum and chitosan due to their outstanding merits. They are simila...

Degeneration of articular cartilage represents one of the most common causes of pain and disability in our aging society. Current treatments only address the symptoms of joint disease, but not their underlying causes which include oxidative stress and inflammation in cartilage and surrounding tissues. Sulfated biopolymers that mimic aspects of the native extracellular environment of cartilage a...

The Pb and Cd binding capacity of alginates were quantified by the determination of their complex stability constants and the concentration of complexing sites using H+, Pb2+, or Cd2+ selective electrodes in both static and dynamic titrations. Centrifugation filter devices (30 kDa filter cutoff), followed by inductively coupled plasma mass spectrometry (ICP-MS) measurements of lead or cadmium i...
