Steroids are among the most widely prescribed drugs for humans, and steroid signaling pathways are present in vertebrates, plants, insects and fungi, presenting new avenues for biotechnological intervention. Genetics of Steroid Biosynthesis and Function focuses on the genetic and cellular aspects of mammalian steroid hormones with particular attention to inherited gene lesions. With contributions from a panel of international experts, this volume provides an accessible, up-to-date overview of modern steroid biology for both the professional and novice researcher alike.

Twistor theory is the remarkable mathematical framework that was discovered by Roger Penrose in the course of research into gravitation and quantum theory. It have since developed into a broad, many-faceted programme that attempts to resolve basic problems in physics by encoding the structure of physical fields and indeed space-time itself into the complex analytic geometry of twistor space.
Twistor theory has important applications in diverse areas of mathematics and mathematical physics. These include powerful techniques for the solution of nonlinear equations, in particular the...
