Mass flow sensor. A mass (air) flow sensor ( MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine . The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure.
A macrophage-activating factor ( MAF) is a lymphokine or other receptor based signal that primes macrophages towards cytotoxicity to tumors, cytokine secretion, or clearance of pathogens. Similar molecules may cause development of an inhibitory, regulatory phenotype. A MAF can also alter the ability of macrophages to present MHC I antigen ...
Macrophage activation syndrome is a severe, potentially life-threatening, complication of several chronic rheumatic diseases of childhood. It occurs most commonly with systemic-onset juvenile idiopathic arthritis (SoJIA). In addition, MAS has been described in association with systemic lupus erythematosus (SLE), Kawasaki disease, and adult ...
Multicentric carpotarsal osteolysis syndrome. This condition is inherited in an autosomal dominant manner. Multicentric carpotarsal osteolysis syndrome (MCTO) is a rare autosomal dominant condition. [2] This condition is also known as idiopathic multicentric osteolysis with nephropathy. It is characterised by carpal - tarsal destruction and ...
List of medical symptoms. Medical symptoms refer to the manifestations or indications of a disease or condition, perceived and complained about by the patient. [1] [2] Patients observe these symptoms and seek medical advice from healthcare professionals.
Mast cell activation syndrome (MCAS) is a term referring to one of two types of mast cell activation disorder (MCAD); the other type is idiopathic MCAD. [1] MCAS is an immunological condition in which mast cells inappropriately and excessively release chemical mediators, resulting in a range of chronic symptoms, sometimes including anaphylaxis or near-anaphylaxis attacks.
Bovine spongiform encephalopathy ( BSE ), commonly known as mad cow disease, is an incurable and invariably fatal neurodegenerative disease of cattle. [ 2] Symptoms include abnormal behavior, trouble walking, and weight loss. [ 1] Later in the course of the disease, the cow becomes unable to function normally. [ 1]
Crankshaft position sensor. A crank sensor (CKP) [ 1][ 2][ 3] is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine ...
