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 ...

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.

Purpose and Function in Biology
1991There is a sense in which biology is a science much narrower in scope than physics. After all, it deals with, so far as we know, systems that make up only a very small part of the universe.1 On the other hand, it is also true that there is an immense diversity in the sorts of organic systems with which it deals.

Functional Explanations in Biology
2000In this chapter I deal with the last of the alleged contradistinctions between holism and reductionism in biology, namely the one between functional explanations (holism) and causal explanations (reductionism).

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.

Plasmids: Their Biology and Functions
2013The genomic constitution of several bacteria may consist of two components, viz., chromosome that carries genes for all essential functions and their regulation, and an extra-chromosomal but autonomous unit, plasmid that was initially thought to carry functions required for its own replication, maintenance, and distribution.

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 ...
