Alzheimer’s disease is a brain disorder that worsens with age and has no known cure. The disease affects different aspects of cognition and memory, and can eventually lead to shutdown of the body. https://www.youtube.com/watch?v=fT7UovfLl8c

Amyloid beta is a short chain amino acid and is a main component of amyloid plaques that are associated with Alzheimer’s. Amyloid beta plaques are located outside of neurons. Amyloid beta plaques are composed of amyloid precursor protein (APP) that is truncated into a shorter form. Amyloid beta toxicity occurs when the build of of amyloid beta plaques becomes toxic to neural cells.

The evolutionary process in which organisms acquire adaptations to allow survival in an environment.

The phenomenon is which two or more alleles are associated more frequently than expected.

Beneficial mutations that increase an organism's survival and reproductive rate are favored by natural selection. That is, alleles that increase an individual’s fitness are increased in frequency. Eventually most beneficial mutations become fixed : their frequency will reach 1. However, mutations increase in frequency but don’t get fixed.

The concentration of a chemical at which effects on the body can be observed.

Different terms are used to standardize the question, "How much of chemical X does this sample contain?" The smallest concentration at which a chemical can be feasibly measured is known as the limit of detection, or LOD. The limit of quantification (LOQ) is the LOD plus any adjustment for known measurement bias or imprecision. LOQ can be thought of as the lowest LOD that can be made confidently.

Because of different instruments and protocols, LOQs vary across studies, which may make comparison difficult. (See definition for "quantification thresholds" above.)

A term used in food safety by the European Commission, a legal body of the European Union: "The traces pesticides leave in treated products are called 'residues.' A maximum residue level (MRL) is the highest level of a pesticide residue that is legally tolerated in or on food or feed when pesticides are applied correctly."

Sensitivity in detecting a chemical of interest. Varying quantification thresholds make comparisons across studies difficult, because there is no standardized baseline measurement. For example, if Lab A uses an instrument that is much more sensitive than Lab B's, then Lab A may report measurements that were too low for Lab B to detect. As a result, Lab B will appear to report higher results than Lab A. (See definition for "limit of quantification (LOQ)" below.)
