Modern concepts of soil conservation

Modern Concepts of Cerebrovascular Disease

The present volume incorporates the papers delivered and the subsequent discussion generated at a Ciba Foundation Symposium having to do with the results of non-traumatic and traumatic injuries to the central nervous system. The symposium was held in London in November of 1974. Its format reflects largely the interest of the symposium's chairman, Dr. Fred Plum of New York, and one of its main p...

Modern Concepts in Evolutionary Genetics

Proceedings of the conference. ABSTRACT RecA protein catalyzes DNA strand exchange, a basic step of homologous recombination. RecA protein possesses two DNA binding sites. During DNA strand exchange, the primary site binds to ssDNA, forming the helical RecA nucleoprotein filament. The weaker secondary site binds dsDNA during the homology search process. Surprisingly, the secondary DNA binding s...

Soil Erosion and Conservation

Modern concepts in diverticular disease.

Over the last decade there has been a striking shift in our understanding of the epidemiology, pathology, and management of diverticular disease. Indeed, many of the guidelines published in the late nineties and early 2000s are now redundant. High-fiber diets, avoidance of nuts and seeds, antibiotic treatment for mild diverticulitis, elective resection after 2 attacks of diverticulitis, Hartman...

Modern concepts in hand orthotics

Boutonniere injury orthosis (1) This orthosis (Figure 1) may be formed by direct application using Prenyl. This material has the advantage of being easily adjusted after immersion in hot water and then setting in cold. The at t i tude of 40 degrees of flexion of the distal end por t ion prevents the orthosis from slipping. Vitrathene and polypropylene may also be used; however, bo th require a ...
