Abstract:
'Beta-cell failure' is a frequently used term to describe the structural and functional inability of the cells to fulfil their metabolic responsibility. This editorial reviews the anatomy and physiology of the beta cell, and describes factors which regulate this. The authors focus on semantics, comparing the phrases 'beta-cell failure', 'functional mass', and 'beta-cell insufficiency'. They suggest the use of 'beta-cell insufficiency', with descriptors such as 'partial' and 'complete', or 'reversible' and 'irreversible', to convey betacell dysfunction in type 2 diabetes. A three-phase taxonomic structure: beta-cell sufficiency, partial/reversible beta-cell insufficiency and complete/irreversible beta-cell insufficiency, is proposed as a tool to understand pathophysiology and facilitate therapeutic decision-making.

Water
The polarity of the water molecule and its resulting hydrogen bonding makes water a unique substance with special properties that are intimately tied to the processes of life. Life originally evolved in an aqueous environment, and most of an organism’s cellular chemistry and metabolism occur inside the aqueous contents of the cell’s cytoplasm. Special properties of water are its high heat capacity...
