RNFL asymmetry has been proposed as a strong indicator of optic neuritis, [7] [8] with one small study proposing that asymmetry of 5–6μm was "a robust structural threshold for identifying the presence of a unilateral optic nerve lesion in MS." [9] Optic neuritis is often associated with multiple sclerosis, and RNFL data may indicate the pace ...
The GDx nerve fiber analyzers measure the retinal nerve fiber layer (RNFL) thickness with a scanning laser polarimeter based on the birefringent properties of the RNFL. Measurement is obtained from a band 1.75 disc diameters concentric to the disc. It projects a polarized beam of a light into the eye.
For dogs and cats, a 9 point body condition score (BCS) system is used to identify whether they are above their ideal weight status. [5] Scores 1-3 indicate 'too thin', 4 and 5 are 'ideal', 6 is 'above ideal', 7 is 'overweight' and 8 and 9 are 'obese'.
Details of structures vary tremendously from breed to breed, more than in any other animal species, wild or domesticated, [1] as dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier that stood only 6.3 cm (2.5 in) at the shoulder, 9.5 cm (3.7 in) in length along the head and body, and weighed only ...
In statistics, a standard normal table, also called the unit normal table or Z table, [1] is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution.

Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
In studies where the interscapular brown adipose tissue of rats were lesioned, it was demonstrated that the rats had difficulty regulating their normal body-weight. [ 61 ] The longest-lived small mammals, bats (30 years) and naked mole rats (32 years), all have remarkably high levels of brown adipose tissue and brown adipose tissue activity.
