Stereotactic radiosurgery (SRS) has been an effective modality for the treatment of benign and malignant cranial disease for over 50 years. Just as SRS revolutionized the practice of neurosurgery, stereotactic ablative radiotherapy (SAbR) in extracranial sites is now challenging conventional wisdom with regard to the practice of radiation oncology. This clinical paradigm change has been enabled...

Since the earliest attempts to raise signifi cant immune responses against nonliving agents, investigators have tried to identify useful additives that can be combined with antigens to enhance immune responses. Such immuneenhancing additives are known as adjuvants. Virtually all adjuvant systems developed to date have focused on one of two mechanisms: specifi c immune activation or the delivery...

My purpose here is to provide brief historical overviews of three related subjects conceptually fundamental to the broader subject of "cell adhesion in development." These subjects are (1) the evolution of our present understanding of how animal cells cohere; (2) the question of what principles underlie the ability of embryonic cell populations to organize themselves into anatomically correct s...

This essay explores the nature of embryonic development in contrast to other kinds of processes. Anhistorical processes are highly reproducible and are therefore subject to standard scientific analysis. Such analyses yield results that may well apply universally. Euhistorical processes are non-reproducible. Therefore they are not subject to standard scientific analysis, but are investigated pri...
