Warm-blooded is a term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals ) maintain a stable body temperature by regulating metabolic processes.
Warm-blooded animals could have gained an advantage by creating an inhospitable environment for many disease-causing organisms, thus reducing the risk of infections. Insulation and Thermoregulation: Homeothermy could have originated as a response to the development of insulating structures like fur, feathers, or other coverings. As animals ...
Secondary cold agglutinin syndrome occurs when autoantibodies bind to red blood cells, rendering them subject to attack by the complement system. [17] It is a result of an underlying condition potentially associated with either monoclonal cold-reacting autoantibodies or polyclonal cold-reacting autoantibodies [16] predominantly caused by infection or lymphoproliferative disorders.

Cold agglutinin disease usually results from the production of a specific IgM antibody directed against the I/i antigens (precursors of the ABH and Lewis blood group substances) on red blood cells (RBCs). Cold agglutinins commonly have variable heavy-chain regions encoded by VH, with a distinct idiotype identified by the 9G4 rat murine ...
A cold weather strategy is to temporarily decrease metabolic rate, decreasing the temperature difference between the animal and the air and thereby minimizing heat loss. Furthermore, having a lower metabolic rate is less energetically expensive. Many animals survive cold frosty nights through torpor, a short-term temporary drop in body ...
Dinosaurs were initially cold-blooded, but global warming 180 million years ago may have triggered the evolution of warm-blooded species, a new study found.
Cold-blooded is an informal term for one or more of a group of characteristics that determine an animal's thermophysiology. These include: Ectothermy, controlling body temperature through external processes, such as by basking in the sun; Poikilothermy, the ability of an organism to function over a wide internal temperature range
Cold hemagglutinin disease: D59.1: 2949: Cold hemagglutinin disease (also known as cold agglutinin disease and autoimmune anemia due to cold-reactive antibodies)is an autoimmune disease characterized by the presence of high concentrations of circulating antibodies, usually IgM, directed against red blood cells.
