Integrin alpha4beta1
In multiple sclerosis (MS), the VLA-4 integrin is essential in the processes by which T-cells gain access to the brain. It allows the cells to penetrate the blood brain barrier that normally restricts immune cell access. It has been found that the severity of MS is positively correlated with the expression of alpha 4.

Just perfect fifth
In music theory, a perfect fifth is the musical interval corresponding to a pair of pitches with a frequency ratio of 3:2, or very nearly so. In classical music from Western culture, a fifth is the interval from the first to the last of the first five consecutive notes in a diatonic scale. The perfect fifth (often abbr...

Predominant chord
Predominant chords both expand away from the tonic and lead to the dominant, affirming the dominant's pull to the tonic. Thus they lack the stability of the tonic and the drive towards resolution of the dominant. The predominant harmonic function is part of the fundamental harmonic progression of many classical works.

Predominant chord
The submediant (vi) may be considered a predominant chord or a tonic substitute.The dominant preparation is a chord or series of chords that precedes the dominant chord in a musical composition. Usually, the dominant preparation is derived from a circle of fifths progression. The most common dominant preparation chords...

Pythagorean minor third
In music theory, a semiditone (or Pythagorean minor third) is the interval 32:27 (approximately 294.13 cents). It is the minor third in Pythagorean tuning. The 32:27 Pythagorean minor third arises in the 5-limit justly tuned major scale between the 2nd and 4th degrees (in the C major scale, between D and F).

Augmented sixth chord
In music theory, an augmented sixth chord contains the interval of an augmented sixth, usually above its bass tone. This chord has its origins in the Renaissance, was further developed in the Baroque, and became a distinctive part of the musical style of the Classical and Romantic periods.Conventionally used with a pre...

Eleventh chord
As its upper extensions (7th, 9th, 11th) constitute a triad, a dominant eleventh chord with the third and fifth omitted can be notated as a compound chord with a bass note. So C–B♭–D–F is written as B♭/C, emphasizing the ambiguous dominant/subdominant character of this voicing. In the common practice period, the root, ...

Minor interval
For example, any two notes an octave apart have a frequency ratio of 2:1. This means that successive increments of pitch by the same interval result in an exponential increase of frequency, even though the human ear perceives this as a linear increase in pitch. For this reason, intervals are often measured in cents, a ...

Chord substitution
In music theory, chord substitution is the technique of using a chord in place of another in a progression of chords, or a chord progression. Much of the European classical repertoire and the vast majority of blues, jazz and rock music songs are based on chord progressions. "A chord substitution occurs when a chord is ...

In music theory, equivalence class is an equality (=) or equivalence between properties of sets (unordered) or twelve-tone rows (ordered sets).

11-limit interval
In music theory, limit or harmonic limit is a way of characterizing the harmony found in a piece or genre of music, or the harmonies that can be made using a particular scale. The term limit was introduced by Harry Partch, who used it to give an upper bound on the complexity of harmony; hence the name.

In music theory, pitch spaces model relationships between pitches.

In music theory, pitch-class space is the circular space representing all the notes (pitch classes) in a musical octave.

For example, C4, C5, and C6, though different pitches, are represented by the same point in p...

Dominant function
In music theory, the dominant triad is a major chord, symbolized by the Roman numeral "V" in the major scale. In the natural minor scale, the triad is a minor chord, denoted by "v". However, in a minor key, the seventh scale degree is often raised by a half step (♭ to ♮), creating a major chord.

Binary logarithm

That is, if tones x, y, and z form a rising sequence of tones, then the measure of the interval from x to y plus the measure of the interval from y to z should equal the measure of the interval from x to z.

Hamming numbers
In music theory, the just intonation of the diatonic scale involves regular numbers: the pitches in a single octave of this scale have frequencies proportional to the numbers in the sequence 24, 27, 30, 32, 36, 40, 45, 48 of nearly consecutive regular numbers. Thus, for an instrument with this tuning, all pitches are r...

Euler's tonnetz provides a convenient graphical representation of the pitches in any 5-limit tuning, by factoring out the octave relationships (powers of two) so that the remaining values form a planar grid.

Scale degrees
For instance, the 7-tone diatonic scale may become the major scale once the proper degree has been chosen as tonic (e.g. the C-major scale C–D–E–F–G–A–B, in which C is the tonic). If the scale has no tonic, the starting degree must be chosen arbitrarily. In set theory, for instance, the 12 degrees of the chromatic scal...

In a more specific sense, scale degrees are given names that indicate their particular function within the scale (see table below). This implies a functional scale, as is the case in tonal music. This example gives the names of the functions of the scale degrees in the seven note diatonic scale.
