A method of using a radiolabeled antibody to quantitate a known antigen.  

A very sensitive method of quantitating a specific antigen using a specific radiolabeled antibody. Functionally, the antibody is made radioactive by the covalent incorporation of radioactive iodine. The radioimmuno probe thus prepared is exposed to its antigen (which may be a protein, or a receptor, etc.) in excess (the exact amount will have to be…

An isotope with an unstable nucleus that spontaneously emits radiation. The radiation emitted includes alpha particles, nucleons, electrons, and gamma rays. An isotope which sends out radiation, used in radiotherapy and scanning. An unstable atom with particles, which when they are released by the atom also results in the release of energy as α, β,…

An equimolar (i.e., equal number of molecules) mixture of the D and L stereoisomers of an optically active compound. A solution of dextrorotary (D) isomer (enantiomer) will rotate the plane in which the light was polarized a specific number of degrees to the right (dextro) while a solution containing the same number of levorotary (L)…

The so-called “royal path,” it concerns itself with the meditation practices one may employ to feel the state of oneness of yoga at one’s core. A type of yoga that is believed to be the foundation for the other yoga systems.  

The rotator cuff is a structure composed of tendons that work along with associated muscles to hold the ball at the top of the humerus in the glenoid socket and provide mobility and strength to the shoulder joint. Collection of muscles that rotate the arm; includes supraspinatus, infraspinatus, teres minor, and subscapularis muscles. A musculotendinous…

These inexpensive latex bands often come in sets of three—light, medium, and heavy resistance. They provide resistance during both upper body and lower body strength exercises.  

The energy expended while an individual is resting quietly in a supine position. The total amount of energy your body uses in a given period of time when at rest. RMR depends on body size, body composition, age, and other factors and can be temporarily affected by activity level and diet. The metabolism that occurs…

Ratio of the volume of CO2 produced to the volume of O2, consumed in the body as a whole. The respiratory exchange ratio is assessed through assessment of expired gases as the volume of carbon dioxide produced divided by the volume of oxygen consumed. RER provides an indication of the respiratory quotient (RQ), which describes…

One inspiration and expiration.
