Biology of female sexual function
Urologic Clinics of North America, 2002Although the psychosocial and relationship aspects of female sexuality have been extensively investigated, studies concerning the anatomy, physiology and pathophysiology of female sexual function and dysfunction are limited. The paucity of biologic data may be attributed to a lack of reliable experimental models and tools for investigating female ...

The Biology and Functions of Th22 Cells
2014T helper (Th) cells develop from naïve CD4(+) T cells under lineage-specific culture conditions and are nominated by their lineage-specific cytokines. Th22 cells, new players in adoptive immune responses, are identified by the production of interleukin (IL)-22.

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

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 ruffled

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.

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 ...

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.

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.
