Genes located on chromosome 6 and encoded for the human leukocyte antigens (HLAs), present on all body cells, that distinguish self from non-self. Their products are primarily responsible for the rapid rejection of grafts between individuals. The function of the products of the MHC is signaling between lymphocytes and cells expressing antigens.

Malnutrition includes deficiency, excess or imbalance of energy, protein and/or other nutrients. In clinical practice, undernutrition is the typical focus resulting from reduced food intake/assimilation or disease burden/inflammation leading to altered body composition and diminished function.

Mast cells play an important role in the body's allergic response. Mast cells are present in most body tissues, but are particularly numerous in connective tissue, such as the dermis (innermost layer) of skin. In an allergic response, an allergen stimulates the release of antibodies, which attach themselves to mast cells. Following subsequent allergen exposure, the mast cells release substances such as histamine (a chemical responsible for allergic symptoms) into the tissue.

designed to measure and track mental status in adults (56-105) with cognitive impairment. The DRS-2 is very useful in the assessment and progression of dementia of Alzheimer's type, vascular dementia, Parkinson's disease, Huntington's disease, and age-related dementia in mental retardation and Down's syndrome. The (DRS-2) is individually administered and is comprised of a 36- task and 32-stimulus card. The DRS-2 assesses cognitive functioning on five subscales: Attention (ATT, 8 items); Initiation-Perseveration (I-P, 11 items); Construction (CONST, 6 items); Conceptualization (CONCEPT, 6 items); and Memory (MEM, 5 items). The reliability and validity properties of the DRS-2 are excellent. The DRS-2 uses the previously established reliability and validity scores. A test-retest reliability correlation coefficient was .97 with subscale correlation coefficients ranging from .61 to .94. The DRS was administered twice with a 1-week interval between administrations to a group of 30 patients

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the presence of hepatic steatosis in conjunction with at least one cardiometabolic risk factor (e.g. elevated waist circumference, blood glucose, blood pressure or dyslipidemia). The term MetALD is used to describe individuals with MASLD who consume greater amounts of alcohol (>140 g/week for women and >210 g/week for men). MASLD was previously referred to as nonalcoholic fatty liver or nonalcohol-related fatty liver disease (NAFLD) and metabolic dysfunction-associated fatty liver disease (MAFLD).

Metabolic syndrome is a collection of risk factors (at least three of the following: large waist circumference, high blood pressure, high fasting blood glucose, high serum triglycerides, low serum HDL cholesterol) that is associated with an increased risk of cardiovascular disease beyond what is expected from individual risk factors.

Methacholine is a pharmacologic agent used to assess airway hyperresponsiveness. Methacholine challenge is the most common method for quantifying airway responsiveness. Responsiveness is determined from the changes in lung function resulting from inhaling increasing concentrations of methacholine. Heightened airway responsiveness to a number of stimuli is characteristic of asthma.
