Reissues and new looks

PlasmoDB v5: new looks, new genomes.

Version 5.1 of PlasmoDB, a resource for malaria parasite genomic and functional genomics datasets, was released in August 2006. This new release includes additional Plasmodium genomes and a newly designed website. The new site reflects the status of PlasmoDB as a member of a linked family of Apicomplexan databases.

New Looks at Old Number Theory

We present three results of number theory that all have classical roots, but also modern aspects. We show how to (1) systematically count the rational numbers by iterating a simple function, (2) find a representation of any prime congruent to 1 modulo 4 as a sum of two squares by using simple properties of involutions and pairs of involutions, and (3) find counterexamples to Euler’s conjecture ...

Lysyl oxidase: new looks on LOX.

The extracellular matrix proteins collagen and elastin determine, to a large extent, the biomechanical properties of the vessel wall. Both molecules are secreted as monomers, but are posttranslationally modified in the extracellular space in order to generate stable polymers. A critical feature of collagen and elastin fibers is the degree of cross-linking. The first step in cross-linking is the...

Lifestyle and youthful looks.

BACKGROUND Lifestyle has been proven to have a dramatic effect on the risk of age-related diseases. The association of lifestyle and facial ageing has been less well studied. OBJECTIVES To identify lifestyle factors that associate with perceived facial age in white north European men and women. METHODS Lifestyle, facial wrinkling and perceived facial age were studied in two cross-sectional ...
