Based on their repeat unit lengths, tandem repeats are broadly classified into three categories: microsatellites (1 6 nucleotides); minisatellites (7 100 nucleotides); and satellites (>100 nucleotides).
The principal GSLs analysed (asialo ganglioside GM2, globotriaosylceramide, GM3 and globotetraosylceramide) were identified based on their glucose unit values by comparison with a 2-AA-labelled dextran standard as previously described in detail [ 46, 47].
For carcinogens, estimates were based on their respective unit risk estimates (UREs), which represent the excess lifetime cancer risk estimated to result from continuous lifetime exposure to an average concentration of 1 μg/m of a particular substance in air.
The classification of these polysaccharides has been based on their structural units: namely, the backbone of CS is composed of repeating disaccharide units of N-acetyl d-galactosamine (GalNAc) and d-glucuronic acid (GlcUA), while DS consists of GalNAc and l-iduronic acid (IdoUA) instead of GlcUA.
GAGs are linear polysaccharides that form the side chains of PGs and have been classified into chondroitin sulfate (CS), dermatan sulfate (DS), heparan sulfate (HS), and heparin based on their structural units.
Whereas these are not evident in the respective oldest subfamilies, SVA_A and LAVA_A, from the B subfamilies onwards the two families can be clearly distinguished based on their VNTR repeat unit content and organization.
Conventional computed tomography (CT) scanners utilising a single X-ray spectrum are able to discriminate several tissues based on their attenuation (Hounsfield units, HU), but the overlap in attenuation of many tissues limits discrimination.
To help address variations in resource utilization types, durations, and costs across study sites, the costs of mental health services other than psychiatric hospitalizations, were based on their relative value units developed from resource utilization and cost data available from the management information systems at each site [ 18, 19].
Patients were assigned to time periods and units based on their admission date and admission unit.
