T2 Mycotoxicosis in Swine Following Topical Application, Intravascular Administration and Inhalation Exposure
Studies were conducted to characterize the clinical signs, pathologic changes and pulmonary and systemic immunity of T-2 toxicosis in swine following a single, topical (15 mg/kg), intravascular (0.6 to 5.4 mg/kg) or inhalation (8 or 9 mg/kg; 20 to 30 percent retention) exposure.

An investigation into the efficacy of MRI T2 in an OA population
Several in vitro studies have shown that T2 is sensitive to some of the pathologic changes that occur in osteoarthritis (OA) such as hydration and the subsequent changes in macromolecular concentration, macromolecular structure, and tissue architecture. In this in vivo analysis, several techniques …

A comparison of muscle damage, soreness, morphology, T2 changes and running performance following an ultramarathon race
… approach has focused on changes in transverse (T2) relaxation times after exercise. Given that inflammation and oedema are proposed as reasons for the changes in T2 times, there may be changes in morphological measurements such as muscle volume and peak cross sectional area. Few studies have …

Entwicklung und Optimierung von Messmethoden zur in-vivo-Bestimmung der MR-Relaxationsparameter T1 und T2 am menschlichen Herzen
Die MR-Relaxationszeiten T1 und T2 können zur Charakterisierung der myokardialen Mikrozirkulation benutzt werden. Die T1-Zeit erlaubt die Berechnung der myokardialen Perfusion, während aus der Kenntnis der T2-Zeit über den BOLD-Effekt der Status der myokardialen Oxygenierung erfasst werden kann. Im …

Sonoelastography of the Supraspinatus Tendon: Correlation Analysis with T2* Mapping of the Supraspinatus Tendon on 3 Tesla MRI
… supraspinatus tendon and 3T shoulder MRI with a T2* mapping sequence. The elasticity was estimated by the strain ratio of the supraspinatus tendon to the deltoid muscle (strain ratio S/D). T2* mapping images were analyzed via an independent external workstation. Correlation analysis was performed …

Hepatic 5'deiodinase activity of Japanese quail using reverse-T2 as substrate: assay validation, characterization, and developmental studies
Using reverse-triiodothyronine, rT3, as substrate, an in vitro 5'deiodinase (5'0) assay was validated for adult Japanese quail, by defining conditions under which activity is proportional to enzyme (protein) concentration and is linear with incubation time. Activity was measured as the release of …
