Cellular and Physiological Effects of Probiotics and Prebiotics

Mini-Reviews in Medicinal Chemistry, 2004
We review the present knowledge on the biological mechanisms of action of probiotics and prebiotics. They include direct effects in the intestinal lumen or on intestinal or immune cells, and indirect mechanisms through modulation of the endogenous microflora (composition or functions such as butyrate production) or of the immune system.

Basic cellular physiology

Abstract This section covers the physiology knowledge required for the MRCEM Primary examination. The section covers basic cellular structure and physiology, as well as physiology of the main organ systems, as outlined within the RCEM Basic Sciences syllabus: respiratory, cardiovascular, gastrointestinal, renal, and endocrine systems.

General and Cellular Physiology

1981
As early as 1665 Robert Hooke discovered that cork was made up of cells, but it was not until 1839 that Schleiden and Schwann developed and enunciated the cell doctrine, which stated that the cell is the unit of structure and function in all organisms. Their studies were based on the use of the light microscope.

Perspectives on molecular and cellular exercise physiology

Journal of Applied Physiology, 1988
A challenge to applied physiologists is to continue to apply new methods to their field. The purpose of this review is to speculate how recent advances in the fields of molecular and cell biology might be applied to exercise physiology to provide greater insights into the mechanisms underlying adaptations to a single bout of exercise and to repeated ...

Basic cellular physiology

2017
This chapter describes basic cellular physiology as it applies to Emergency Medicine, and in particular the Primary FRCEM examination. The chapter outlines the key details of homeostasis, compartments and fluid spaces, cell structure and function, vessel fluid dynamics, blood flow, neurological action potential, generated action potential ...

Hypothermia and cellular physiology.

Arctic medical research, 1992
Temperature has pronounced and complex effects on cellular physiology. Rates of enzymatic processes display an exponential change with temperature, as expressed by the Q10 relationship. The basis of these effects may be temperature induced phase transitions in membrane lipids and protein associated water, effects on bulk water and effects on the ...

The diversity of cellular proteinases in physiology and pathology

1977
1. It is suggested that the functions of cellular proteinases are far more diverse than has usually been realized. 2. A scheme is proposed in which isolation of a pure proteinase leads to a rather detailed exploration of its biological significance. 3. Representative proteinases from the serine, thiol, carboxyl and metallo-classes are briefly reviewed ...
