Morphology and twentieth-century biology: A response

Journal of the History of Biology, 1981
I am gratified to find that ideas I published a few years ago in Life Science in the Twentieth Century have stimulated a controversy about some important issues in the history of biology. In the Introduction to that book I wrote, "If this book has any lasting merit . .. it will be less in the questions that it answers than in those it raises . . .

The biology of pancreatic cancer morphology

Pathology, 2022
Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal of all human malignancies. PDAC precursor lesions, invasive primary PDAC, and metastatic PDAC each display distinct morphologies that reflect unique biology. This 'biomorphology' is determined by a complex neoplastic history of clonal phylogenetic relationships, geographic locations ...

Morphology and biology of cerebellar neuroblastomas

Journal of Neuro-Oncology, 1983
A nodular neuroblastoma was partially removed from the cerebellar vermis of a 15-month-old boy. Postoperative irradiation and chemotherapy were performed. More than 5 years later, re-operation revealed a mature ganglioglioma. Problems relating to the maturation of ganglionic tumors are discussed.

Functional morphology and evolutionary biology

Acta Biotheoretica, 1980
In this study the relationship between functional morpholoy and evolutionary biology is analysed by confronting the main concepts in both disciplines. Rather than only discussing this connection theoretically, the analysis is carried out by introducing important practical and experimental studies, which use aspects from both disciplines.

Glioblastoma multiforme: Morphology and biology

Acta Neurochirurgica, 1978
Glioblastoma multiforme, representing about 50% of all gliomas, encompasses a group of intrinsic tumours of the brain in later years (age peak around 50 years), the morphological hallmarks of which are an ensemble of variations in tumour cell and tissue structure featuring its biological malignancy. Glioblastoma, while sometimes appearing as a distinct
