At the end of the nineteenth century, Wilhelm Conrad Roentgen discovered X-rays and Henri Becquerel discovered radioactivity. In the early years after that, there was a lot of misunderstanding regarding the effects of ionizing radiation and its practical applications. Medical employment of ionizing ...

This brief history reviews the evolution of "experimental radiotherapy" over the past century and describes how the development of new technologies and new experimental models influenced this field of study. In addition, it describes critical points at which studies in radiation biology and biology ...
Treatment of patients with transformed lymphoma presents a significant challenge to the practicing physician. Indeed, the transformation of follicular lymphoma to a more aggressive histology is inherent to the biology of this disease and is often associated with an aggressive clinical course, resulting in...

Third, the overall evolutionary history of spiders is summarized in the form of an evolutionary tree, which is subsequently used to address key issues of broad interest, such as origins, diversifications and extinctions, including the effects of mass extinctions and predator–prey co-radiations. ...
A brief chapter on the relationship of D20 to radiation sensitivity of biological objects emphasizes the contradictory nature of the results in this area. This volume represents a review of the literature and contains an author and subject index. This is a very short history of biology and ...
is based on variation in Darwinian fitness among individuals, and since life history traits determine survival and reproduction they are the major components of fitness. The study of life history evolution is thus about understanding adaptation, the most fundamental issue in evolutionary biology. ...
