Graves’ disease (GD) is a complex genetic autoimmune thyroid diseases (AITD). TSHR is considered as candidate gene in GD. IL1RN gene shown to be related to the pathogenesis of a number of autoimmune diseases. These finding prompted us to investigate the association of TSHR and IL1RN genes polymorphism with the risk and the prognosis of GD in Tunisia. A total of 249 healthy controls and 68 GD pa...

Graves' disease (GD) is an organ-specific autoimmune thyroid disease; 25-50% of GD patients will develop Graves' ophthalmopathy (GO). The etiology of GD and GO may be multifactorial, but the immune response plays a central role. Many studies have reported that IL-21 has crucial roles in autoimmune diseases. We examined whether IL-21 is associated with the development of GD and GO. The ser...

Two new potential magnetic resonance imaging contrast agents, Gd-hematoporphyrin (Gd-H) and Gd-tetra-carboranylmethoxyphenyl-porphyrin (Gd-TCP), were synthesized and applied to nude mice with human melanoma (MM-138) xenografts. These agents showed a high relaxivity because of their greater potential to coordinate water molecules. The reduction of T1 relaxation times of 16 and 21% was observed i...

Gd(III) complexes have emerged as spin labels for distance determination in biomolecules through double-electron-electron resonance (DEER) measurements at high fields. For data analysis, the standard approach developed for a pair of weakly coupled spins with S = 1/2 was applied, ignoring the actual properties of Gd(III) ions, i.e. S = 7/2 and ZFS (zero field splitting) ≠ 0. The present study re...

BACKGROUND Graves' disease (GD) is a complex disease in which genetic predisposition is modified by environmental factors. The aim of the study was to examine the association between genetic variants in genes encoding proteins involved in immune response and the age at diagnosis of GD. METHODS 735 GD patients and 1216 healthy controls from Poland were included into the study. Eight genetic va...

The coexistence of Graves’ disease (GD), also known as Basedow’s disease, and ulcerative colitis (UC) is uncommon although both conditions involve the autoimmune process. This report reviews the Englishand Japanese-language literature on coexisting hyperthyroidism and UC, and discusses cases of concomitant GD and UC reported since 1980. Of the 16 cases of concomitant GD and UC that were identif...

Lecithin microcapsules containing gadolinium (Gd) were designed and prepared as a dosage form for intraarterial administration to accumulate Gd in tumors in neutron capture therapy. The microcapsules were composed of 1) a lactose core, 2) a layer of distearylamide of gadopentetic acid (Gd-DTPA-SAm) and polyvinylpyrrolidone (PVP) with or without soybean lecithin (SL) and 3) a membrane containing...

We have studied the receptor-specific function of four linker-insertion mutants of herpes simplex virus type 1 glycoprotein D (gD) representing each of the functional regions of gD. We used biosensor analysis to measure binding of the gD mutants to the receptors HVEM (HveA) and nectin-1 (HveC). One of the mutants, gD(inverted Delta 34t), failed to bind HVEMt but showed essentially wild-type (WT...

BACKGROUND To prospectively evaluate an elastin-specific MR contrast agent (ESMA) for in vivo targeting of elastic fibers in myocardial infarction (MI) and postinfarction scar remodeling. METHODS AND RESULTS MI was induced in C57BL/6J mice (n=40) by permanent ligation of the left anterior descending coronary artery. MRI was performed at 7 and 21 days after MI. The merits of gadolinium-based E...

The aim of the present study was to investigate the effect of Apelin-13 on cardiomyocyte autophagy and to determine the underlying mechanism of this effect. To establish an autophagic model system, the cardiomyocytes of Sprague Dawley rats (postnatal day 3) were cultured and divided into five groups: normal control (Co), glucose deprivation (GD), GD+Apelin-13, GD+Apelin-13 treated with the Akt-...
