Glomerulonephritis (GN) is a term used to refer to several kidney diseases (usually affecting both kidneys). Many of the diseases are characterised by inflammation either of the glomeruli or of the small blood vessels in the kidneys, hence the name, [1] but not all diseases necessarily have an inflammatory component.
Crescentin was discovered in 2009 by Christine Jacobs-Wagner in Caulobacter crescentus (now vibrioides), an aquatic bacterium which uses its crescent-shaped cells for enhanced motility. [1] The crescentin protein is located on the concave face of these cells and appears to be necessary for their shape, as mutants lacking the protein form rod ...
Terriers are smaller dogs which can be used to hunt small animals such as birds and rabbits. [41] Gun dogs are mostly used during upland and wetland hunting to retrieve downed game. [ 41 ] Hounds typically specialize in the chase and utilize a variety of noises to flush out game, used in hunting larger mammals such as deer, coyote, boar, and foxes.
A domestication process then began to develop. The earlier association of dogs with humans may have allowed dogs to have a profound influence on the course of early human history and the development of civilization. [5] The questions of when and where dogs were first domesticated have taxed geneticists and archaeologists for decades. [11]
The most important aspect and defining characteristic of protein from a nutritional standpoint is its amino acid composition. [43] For all animals, some amino acids are essential (an animal cannot produce them internally so they must be eaten) and some are non-essential (the animal can produce them from other nitrogen-containing compounds ...
In physiology, thermoception or thermoreception is the sensation and perception of temperature, or more accurately, temperature differences inferred from heat flux.It deals with a series of events and processes required for an organism to receive a temperature stimulus, convert it to a molecular signal, and recognize and characterize the signal in order to trigger an appropriate defense response.
This is important because the core temperature of mammals can be controlled to be as close as possible to the optimal temperature for enzyme activity. The overall rate of an animal's metabolism increases by a factor of about two for every 10 °C (18 °F) rise in temperature, limited by the need to avoid hyperthermia. Endothermy does not provide ...
Skeletons of humans and birds compared by Pierre Belon, 1555 The first specifically anatomical investigation separate from a surgical or medical procedure is associated by Alcmaeon of Croton . [ 3 ] Leonardo da Vinci made notes for a planned anatomical treatise in which he intended to compare the hands of various animals including bears. [ 4 ]
