Abstract
This chapter discusses the photosystem II (PSII) reconstitution into proteoliposomes. In the first part of the chapter, protocols are outlined for the preparation of lipid bilayer vesicles (liposomes) constituted of individual thylakoid lipids or their mixtures, for the preparation of PSII particles...

Abstract
Roe deer antlers/mandibles are a useful tool for determination of ambient fluoride pollution. Antlers have a well-defined annual cycle of growth, therefore they represent a natural standardisation of samples during winter months. On the contrary, mandibles accumulate fluorides during the whole life...

Abstract
Dental caries affects the majority of the Danish population. Its aetiology is multi-factorial, but a pH-induced change in the homeostasis of the oral biofilm leading to overgrowth of acid-tolerating bacteria is a key event. A non-invasive concept for prevention and management is emerging based on th...

Dental update (37)9 2010
Abstract
Fluoride has been used in dentistry for over 100 years for the purpose of preventing dental caries. During this time there has been great debate over the mode of action, the optimum method of delivery, and the potential risks associated with its use. This, the first of three papers, will provide a s...
