We have recently demonstrated that proteolytic activity of lysosomal acid proteases from papillary carcinoma is significantly higher than in morphologically normal thyroid tissue. In the present study the activity of lysosomal acid proteases from parenchymatous proliferated thyroid epithelium,
The purpose of the investigation was to comparatively study the possible clinicodiagnostic and clinicoprognostic value of thyroglobulin (TG) autoantibodies (anti-TG autoAB) and thyroid peroxidase (TPO) (anti-TPO autoAB) with proteolytic activity (protease-AB) and to develop additional
The lysosomal acid protease is thought to be a main enzyme in hydrolysis of thyroglobulin. The protease activity of lysosome-rich fractions of various diseased thyroid glands were assayed by the sensitive and reproducible method developed in our laboratory. They included 78 diseased thyroid glands;
A 37-yr-old woman with nontoxic goiter is presented. The thyroid 131I uptake at 3 and 24 hr were, respectively, 77.1% and 81.4% dose. Thiocyanate discharged 65.5% of the accumulated 131I in 30 min. In vitro organification of iodine in the thyroid homogenate from the patient was impaired and it was
Introduction. SERPINE2 and secretory leukocyte protease inhibitor (SLPI) are proteins with anticoagulant properties which could promote solid tumor growth. However, their role in the pathogenesis of thyroid cancer has not been determined. Materials and Methods. The aim of this study was to assess
OBJECTIVE
The composition of sugar chains on thyroglobulin (Tg) produced in thyroid carcinoma cells (C-Tg) is different from Tg produced in normal thyroid tissues (N-Tg). In this study, we designed a new method for detecting Tg derived from thyroid carcinoma based on the differences between C-Tg and
Free bradykinin, kininogen, kininase, protease inhibitors of alpha 1-antitrypsin, alpha 1-antichymotrypsin, alpha 2-macroglobulin, and antitryptic volume of the blood serum were examined in 25 patients suffering from goiter with thyrotoxicosis symptoms. Activation of the kinin system and reduction
The optimal demonstration of estrogen receptor binding in thyroid tissues was made under conditions of 10% protease in 50 mM Tris-HCl buffer (pH 7.6) for 10 min as the pretreatment digestion step, incubation of primary antibody (ER-ICA monoclonal kit; Abbott Laboratories) at 37 degrees C for 2 h and
Ninety-seven fixed surgical thyroid specimens and 63 unfixed and 40 fixed thyroid specimens from autopsies were examined for their oxalate content. Proteases were used to process the tissue, and the oxalate was determined with an enzymatic assay. The fixed samples were grouped into seven diagnostic
According to current guidelines, (201)Tl scintigraphy aiming at the detection of iodine-negative metastases of differentiated thyroid carcinoma is usually performed during hormone replacement in thyroid-stimulating hormone (TSH)-suppressive doses. The aim of this study was to determine the effect of
We report a case of avascular necrosis (AVN), hypercalcemia, and iatrogenic Cushing's syndrome in an HIV-positive patient taking inhaled (ICS) and nasal corticosteroids fluticasone and ritonavir. A 45-year-old HIV-infected African-American woman was seen for initial evaluation for multinodular
The activation of adenylate cyclase of human thyrocytes in primary cell cultures and the release of cAMP into the medium are used to detect thyrotropin (TSH) and thyroid-stimulating antibodies (TSAb) in sera of patients with Graves' disease. Tissue digestion and cell dispersion are performed using a
We produced antibodies against a thyroid papillary carcinoma homogenate (PCAb) and analyzed antigens recognized by this antibody using western blotting. Fifty-four thyroid tissue specimens and 6 control tissue specimens obtained from non-thyroid carcinoma (gastric tissue, colon and liver) were
Cystatin C (Cys C) is a cysteine protease inhibitor produced at a constant rate by nucleated cells, filtered through the glomerular membrane and reabsorbed by kidney tubular cells. Aim of this cross-sectional and longitudinal study was to assess serum Cys C and creatinine (Crea) concentrations in
