Until recently, stimulating TSH receptor autoantibodies (sTRAbs) could only be measured by bioassays. A new assay system, which directly detects sTRAb in sera by applying bridge technology, has been established and is now available as automated chemiluminescence (bridge) immunoassay. We evaluated the automated bridge assay in clinical routine and compared it with a conventional automated TRAb assay (competition assay). Altogether, 226 Graves' disease (GD), 57 autoimmune thyroiditis, 74 non-autoimmune nodular goiter and 49 thyroid cancer patients, as well as 41 healthy controls were retrospectively evaluated...

We analyzed gene expression profiles of young and aged mouse CD8(+) T cells specific for the nucleoprotein (NP) of influenza A/PR8/34 virus. CD8(+) T cells were stimulated either by the NP antigen expressed in its native form or fused into the herpes virus (HSV)-1 glycoprotein D (gD) protein, which blocks signaling through the immunoinhibitory B and T lymphocyte attenuator (BTLA) and CD160 pathways. We show that NP-specific CD8(+) T cells from aged mice exhibit numerous differences in gene expression compared to NP-specific CD8(+) T cells from young mice, including a significant reduction of expression in genes involved in T cell receptor (TcR) and CD28 signaling...

OBJECTIVE: To present the diagnostic workup in an extremely low birth weight infant patient with signs of both sepsis and hemophagocytosis. PARTICIPANTS: A preterm infant presented with clinical and laboratory signs of early-onset sepsis including hepatosplenomegaly, thrombocytopenia, direct hyperbilirubinemia, and elevated liver enzymes. METHODS: Despite extensive septic workup, no underlying infection was detected. Additional hyperferritinemia and other elevated inflammatory parameters raised the suspicion of a primary or secondary hemophagocytic lymphohistiocytosis (HLH)...

The present generation of women of childbearing age more frequently suffer from overweight, obesity, initial as well as fully established metabolic syndrome, which together with postponing motherhood until the third decade in life plays an important role in the increasing incidence of gestational diabetes (GDM) that currently affects about 1/5 of pregnant women. However the causal link between diabetes during pregnancy and metabolic diseases in the whole population is mutual. By way of epigenetic changes, maternal diabetes unfavourably programmes metabolism of the offspring, who tend to transfer the disorder to the next generations...

Properties of water molecules at the interface between contrast agents (CAs) for magnetic resonance imaging and macromolecules could have a valuable impact on the effectiveness of metal chelates. Recent studies, indeed, demonstrated that polymer architectures could influence CAs' relaxivity by modifying the correlation times of the metal chelate. However, an understanding of the physico-chemical properties of polymer/CA systems is necessary to improve the efficiency of clinically used CAs, still exhibiting low relaxivity...

BACKGROUND: MRCP is the method of choice in diagnosing pathologies of the biliary system. One of them is bile fistulae. They are uncommon but tend to cause many diagnostic problems. The possible way to improve MRCP is using it with intravenous injection of hepatobiliary-specific contrast agents. As it is eliminated via the hepatobiliary system, it can be visualized in the bile ducts and may help to reveal disorders undetected by a standard MRCP. CASE REPORT: We report a case of a 36-year-old woman with leakage in the biliary system which led to creation of a subcutaneous bile reservoir...

Transient Receptor Potential Canonical type 5 (TRPC5) is a Ca(2+) permeable cation channel that is highly expressed in the brain and is implicated in motor coordination, innate fear behavior, and seizure-genesis. The channel is activated by a signal downstream of the G-protein-coupled receptor (GPCR)-Gq/11-phospholipase C (PLC) pathway. In this study, we aimed to identify the molecular mechanisms involved in regulating TRPC5 activity. We report that R593, a residue located in the E4 loop near the TRPC5's extracellular Gd(3+)-binding site, is critical for conferring the sensitivity to GPCR-Gq/11-PLC-dependent gating on TRPC5...

BACKGROUND: Gestational hypertensive diseases (GHD) and gestational diabetes mellitus (GDM) increase the risk of cardiovascular disease (CVD) later in life. However, the association between gestational medical diseases and familial history of CVD has not been investigated to date. In the present study, we examined the association between familial history of CVD and GHD or GDM via reliable questionnaires in a large cohort of registered nurses. METHODS: The Korean Nurses' Survey was conducted through a web-based computer-assisted self-interview, which was developed through consultation with cardiologists, gynecologists, and statisticians...

The leading causes of morbidity and mortality globally are cardiovascular diseases, and nanomedicine can provide many improvements including disease-specific targeting, early detection, and local delivery of diagnostic agents. To this end, we designed fibrin-binding, peptide amphiphile micelles (PAMs), achieved by incorporating the targeting peptide cysteine-arginine-glutamic acid-lysine-alanine (CREKA), with two types of amphiphilic molecules containing the gadoliniuim (Gd) chelator diethylenetriaminepentaacetic acid (DTPA), DTPA-bis(stearylamide)(Gd), and 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[(poly(ethylene glycol) (PEG))-2000]-DTPA(Gd) (DSPE-PEG2000-DTPA(Gd))...

A woman in her 50s was admitted to our hospital because of multiple tumors detected in her liver. She was diagnosed with combined hepatocellular cholangiocarcinoma using gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) and biopsy of the liver tumors. We judged the tumors to be unresectable because they were found in both lobes of the liver, with a tumor thrombus being found in the main left portal vein. The pathological findings showed that the tumors exhibited characteristics of hepatocellular carcinoma...

: Elevated circulating ferritin has been reported to increase the risk of gestational diabetes mellitus (GDM). When high ferritin translates into high iron stores, iron excess is also a condition leading to free radical damage. We aimed to evaluate the relationship between oxidative stress (OS) induced by iron status and GDM risk in non iron-supplemented pregnant women. METHODS: This was a pilot observational study conducted on 93 non-anemic pregnant women. Iron status was assessed at the first trimester of gestation...

The study was designed to evaluate the effect of ulinastatin on the permeability of the blood-brain barrier in rats with global cerebral ischemia/reperfusion injury using MRI. A total of 108 Wistar rats (240 g-280g) were randomly divided into three groups (n=36): sham group (S group), global cerebral ischemia/reperfusion model group (GCI/R group) and 10,000U/kg ulinastatin intervention group (U group). Fifty-four Wistar rats were used for MRI, and the rest were used for Evans Blue(EB)analysis. We used the Pulsinelli four-vessel occlusion (4-VO) model of global cerebral ischemia/reperfusion to investigate the integrity of the blood-brain barrier with Evans Blue (EB) staining at 15min after ischemia and at 6h (n=6), 24h (n=6), and 48h (n=6) after reperfusion to assess blood-brain barrier permeability with MRI...

In this study, we identify gene targets and cellular events mediating the teratogenic action(s) of 5-Aza-2'-deoxycytidine (AzaD), an inhibitor of DNA methylation, on secondary palate development. Exposure of pregnant mice (on gestation day (GD) 9.5) to AzaD for 12hrs resulted in the complete penetrance of cleft palate (CP) in fetuses. Analysis of cells of the embryonic first branchial arch (1-BA), in fetuses exposed to AzaD, revealed: 1) significant alteration in expression of genes encoding several morphogenetic factors, cell cycle inhibitors and regulators of apoptosis; 2) a decrease in cell proliferation; and, 3) an increase in apoptosis...
