Cardiac Biomarkers in Hyperthyroid Cats
Background: Hyperthyroidism has substantial effects on the circulatory system. The cardiac biomarkers NT-proBNP and troponin I (cTNI) have proven useful in identifying cats with myocardial disease but have not been as extensively investigated in hyperthyroidism. Hypothesis: Plasma NT-proBNP and …

Evaluation of hemostasis in hyperthyroid cats
Background: Hyperthyroid cats are predisposed to thrombus formation. The mechanism for thrombogenesis is currently unknown, but could be associated with altered hemostasis as seen in hyperthyroid humans. Objective: The purpose of this study was to evaluate markers of hemostasis in hyperthyroid cats …

Evaluation of Thyroid to Background Ratios in Hyperthyroid Cats
Hyperthyroidism is the most common feline endocrinopathy. 131I is the treatment of choice, and over 50,000 cats have been treated using an empirical fixed dose. Better treatment responses could be achieved by tailoring the dose based on the severity of disease. Scintigraphy is the best method to …

Evaluation of a Feline-Optimized TSH Assay in Cats With Hyperthyroidism and With Non-Thyroidal Illness
About 10% of hyperthyroid cats have a normal total T4 (TT4), requiring further testing to make the diagnosis. Thyroid stimulating hormone (TSH) is measured using the "canine" assay (TSH-CLIA, Immulite 2000 by Siemens) as the only assay currently available. However, this assay cannot differentiate …

Regulation of LKB1-STRAD-MO25 Complex Expression and Activation of AMPK in Skeletal Muscle by Thyroid Hormone
… are increased in skeletal muscle tissue of hyperthyroid rats. Activity of AMPK is regulated by an upstream kinase (AMPKK). The LKB1-STRAD-MO25 complex is a major AMPKK in skeletal muscle. This experiment was designed to determine whether the increase in AMPK activity is accompanied by a …

Developmental influences of thyroid hormones on the rat olfactory receptor sheet
… normal, hypothyroid, hypothyroid/recovery and hyperthyroid rats to measure olfactory neuronal proliferation and maturation.

Plasma N-terminal Proatrial Natriuretic Peptide Concentration in Cats with Hypertrophic Cardiomyopathy
… variables was evaluated. Cats that were hyperthyroid or had evidence of renal disease were excluded from the study. Results: The mean plasma [Nt-proANP] was higher in cats with HCM (3.81 +/- 1.23 pmol/l) than in control cats (3.08 +/- 1.41 pmol/l); however, this difference was not …

Investigation of a novel modified fixed dose determination protocol for radioiodine treatment of feline hyperthyroidism
… is the treatment of choice for feline hyperthyroidism. The ideal method of dose determination of 131I remains controversial. Objective: To compare a method of radioiodine dose determination that utilized thyroid scintigraphy with a standard fixed dose for treatment of feline …

Basal Release of Endothelium-derived Nitric Oxide in Thyropathologic Rat Aorta
… catecholamine levels were determined for hyperthyroid (TRX), hypothyroid (PTU), and euthyroid control (CON) rats. All three measurements were elevated in TXX animals, while PTU rats were determined to have decreased measurements when compared with CON and TRX rats. Animals were sacrificed …

Characterization of 5-Hydroxytryptamine-Evoked Isometric Contractile Responses in Aortic Vascular Smooth Muscle in Thyropathological Rats
… characterized. Procedure. Aortic rings from hyperthyroid (TRX),hypothyroid (PTU), and euthyroid control (CON) rats were mounted in climate controlled tissue baths and subjected to isometric contraction experiments. The endothelium was removed from some rings (denuded) while others were left …

The Effect Of Streptozotocin-induced Diabetes And Thyroid Hormone Alterations On Skeletal Muscle Contractile, Histochemical And Biochemical Properties
… and biochemical data confirmed the presence of a hyperthyroid state despite normal muscle functional parameters.;These data suggest that full expression of thyroid hormone levels is altered in the diabetic state. An interactive effect between insulin and thyroid hormone is postulated. The decline …

Regulation of Secretory Phospholipase A2 by Thyroid Hormone
… of PLA2g2a and other sPLA2 isoforms. Both hyperthyroid rats and mice had significantly lower levels of PLA2g2a as compared to hypothyroid rats and mice. My data suggest that the thyroid status modulates aspects of the inflammatory response. In contrast with the established role of T3 to …

Efficacy of single fixed dose of radioiodine (I-131) therapy in patients with hyperthyroidism at Groote Schuur Hospital
