Macrophage polarization is a process by which macrophages adopt different functional programs in response to the signals from their microenvironment. This ability is connected to their multiple roles in the organism: they are powerful effector cells of the innate immune system, but also important in removal of cellular debris, embryonic development and tissue repair.
Circular polarizer/linear analyzer [1] filtering unpolarized light and then circularly polarizing the result. A polarizing filter or polarising filter (see spelling differences) is a filter that is often placed in front of a camera lens in photography in order to darken skies, manage reflections, or suppress glare from the surface of lakes or the sea.
Macrophages are found in essentially all tissues, [4] where they patrol for potential pathogens by amoeboid movement. They take various forms (with various names) throughout the body (e.g., histiocytes, Kupffer cells, alveolar macrophages, microglia, and others), but all are part of the mononuclear phagocyte system.
Macro photography (or photomacrography [1] [2] or macrography, [3] and sometimes macrophotography [4]) is extreme close-up photography, usually of very small subjects and living organisms like insects, in which the size of the subject in the photograph is greater than life-size (though macrophotography also refers to the art of making very ...
In general the two rays will be in different polarization states, though not in linear polarization states except for certain propagation directions relative to the crystal axis. A Nicol prism A Nicol prism was an early type of birefringent polarizer, that consists of a crystal of calcite which has been split and rejoined with Canada balsam .
The mononuclear phagocyte system and the monocyte macrophage system refer to two different entities, often mistakenly understood as one. [ citation needed ] " Reticuloendothelial system " is an older term for the mononuclear phagocyte system, but it is used less commonly now, as it is understood that most endothelial cells are not macrophages .
Photo psychology or photopsychology is a specialty within psychology dedicated to identifying and analyzing relationships between psychology and photography. [1] Photopsychology traces several points of contact between photography and psychology.
In photography, solarization is the effect of tone reversal observed in cases of extreme overexposure of the photographic film in the camera. Most likely, the effect was first observed in scenery photographs including the sun. The sun, instead of being the whitest spot in the image, turned black or grey.
