Homeostasis as the Mechanism of Evolution. [PDF]
Homeostasis is conventionally thought of merely as a synchronic (same time) servo-mechanism that maintains the status quo for organismal physiology. However, when seen from the perspective of developmental physiology, homeostasis is a robust, dynamic ...

Are physiological oscillationsphysiological?
AbstractDespite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function. Here, we take a systems approach to argue that oscillations play critical physiological roles, such as enabling ...

Physiology in Perspective [PDF]
This issue of Physiology features four excellent review articles that highlight current research and discuss untapped areas for future work across a range of topics in physiology. First, we explore the impact that the loss of the Y chromosome in white blood cells has on men’s health.

Mitochondrial physiology [PDF]
As the knowledge base and importance of mitochondrial physiology to evolution, health and diseaseexpands, the necessity for harmonizing the terminologyconcerning mitochondrial respiratory states and rates has become increasingly apparent. Thechemiosmotic theoryestablishes the mechanism of energy transformationandcoupling in oxidative phosphorylation ...

Prognostic value of pulmonary dead space in patients with the acute respiratory distress syndrome. [PDF]
A study published in the previous issue of Critical Care demonstrates that measurement of the pulmonary dead-space fraction is superior to hypoxemia as an indicator of a favorable physiologic response to prone positioning in patients with severe acute ...

Roles of lipocalin-type and hematopoietic prostaglandin D synthases in mouse retinal angiogenesis
Normal angiogenesis is essential for retinal development and maintenance of visual function in the eye, and its abnormality can cause retinopathy and other eye diseases. Prostaglandin D2 is an anti-angiogenic lipid mediator produced by lipocalin-type PGD

The Vaginal Microenvironment: The Physiologic Role of Lactobacilli
In addition to being a passage for sperm, menstruum, and the baby, the human vagina and its microbiota can influence conception, pregnancy, the mode and timing of delivery, and the risk of acquiring sexually transmitted infections.

Vascular Calcification and Stone Disease: A New Look towards the Mechanism
Calcium phosphate (CaP) crystals are formed in pathological calcification as well as during stone formation. Although there are several theories as to how these crystals can develop through the combined interactions of biochemical and biophysical factors,
