Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Diatoms have ornate biosilica frustules that are species-specific and are formed under genetic control. We have observed interesting changes in the shape of diatoms both in laboratory cultures and in nature when they are exposed to different environmental conditions such as flow rate or UV radiation. It has been recently discovered that biosilica formation is facilitated by a variety of biological organic molecules. For example, it is proposed that silaffin proteins and ‘small' propylamines are involved in diatom biosilicification. In order to us help to understand the role(s) of organic biomolecules in vivo, model in vitro studies have been carried out where synthetic and biological molecules have been studied for their effects on silica formation. The study of silica formation using R5 peptide which is derived from silaffin proteins is one such example. An interesting observation is that flow can change the structure of both synthetic and biological minerals.
