Endogenous Opioids: Biology and Function
Annual Review of Neuroscience, 1984even less so. It was therefore impossible for the functionally minded neuro scientist to design and execute experiments taking this heterogeneity into consideration. Even pharmacological studies with these peptides were difficult to interpret in a physiological framework.

Acta Biotheoretica, 1958
In this paper we intend to propose a definition of function in biology. First we delimitated the problem and pointed out that a definition must not be related to hypotheses such as the causal connexion between form and function, phylogenetics or evolution, but that only the existence of functions is to be considered. The elements to be expressed in the

Leptin: Structure, Function and Biology
2005Leptin is an adipocyte-derived hormone that acts as a major regulator for food intake and energy homeostasis. Leptin deficiency or resistance can result in profound obesity, diabetes, and infertility in humans. Since its discovery, our understanding of leptin's biological functions has expanded from anti-obesity to broad effects on reproduction ...

The cell biology of osteoclast function
Journal of Cell Science, 2000ABSTRACT Osteoclasts are multinucleated cells responsible for bone resorption. They have developed an efficient machinery for dissolving crystalline hydroxyapatite and degrading organic bone matrix rich in collagen fibers. When initiating bone resorption, osteoclasts become polarized, and three distinct membrane domains appear: a ...

Functional morphology and evolutionary biology
Acta Biotheoretica, 1980In 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.

The biology and function of fibroblasts in cancer
Nature Reviews Cancer, 2016Among all cells, fibroblasts could be considered the cockroaches of the human body. They survive severe stress that is usually lethal to all other cells, and they are the only normal cell type that can be live-cultured from post-mortem and decaying tissue.

Biology and Function of Stem Cells
2015Looking for the exact definition of stem cell is sometimes the source of endless semantical debates. There are two generally accepted criteria: a high capacity for self-renewal and the potential for multipotent or pluripotent differentiation. Stem cells are unspecialized cells that renew themselves through series of cell divisions, which result in ...

Functional Explanation in Biology
Philosophy of Science, 1965This paper is concerned with the problem of giving a correct analysis of function statements as they are used in biology. Examples of such statements are (1) The function of the myelin sheath is to insulate the nerve fiber and (2) The function of chlorophyll is to enable photosynthesis to take place.
