Coupled plasma filtration and adsorption (CPFA) is a detoxification system that combines a plasma adsorption circuit and a continuous renal replacement therapy circuit. Its main application is for sepsis and septic shock with or without acute renal failure. Several recent studies have suggested that CPFA can reduce the mortality when the volume of plasma absorbed on the styrenic resin is at least >0.18 L/kg/day. At present, new applications for CPFA are under investigation, also in patients without significant kidney failure...

BACKGROUND: Abnormal thyroid hormone (TH) metabolism is significantly associated with impaired left ventricular (LV) function and death. Although TH was traditionally thought to be produced exclusively by the thyroid gland, an increasing number of studies report TH production in other tissues. Based on these findings, we evaluated whether the genes required for TH biosynthesis are expressed in the human heart, and whether their expression is altered in patients with ischemic cardiomyopathy (ICM) and is related to epigenetic variations...

Nonalcoholic fatty liver disease (NAFLD) is a major health problem worldwide, and is often associated with lipotoxic injury, defective mitochondrial function, and insulin resistance. Thyroid hormones (THs) are important regulators of hepatic lipid metabolism. Among the THs, diiodothyronine (T2) and triiodothyronine (T3) have shown promising results in lowering hepatic fat content in various models of NAFLD. In this study, we used a targeted metabolomics approach to investigate the differential effects of T2 and T3 on the early metabolic adaptation in the livers of rats fed high fat diet (HFD), a period when hepatosteatosis is reversible...

This study aims to estimate the incidence of hypothyroidism (HT) and to evaluate the predictors affecting the development of HT after radiotherapy (RT) for breast cancer, with a focus on radiation dose-volumetric parameters. Between 2009 and 2015, 243 patients undergoing RT for breast cancer were retrospectively analyzed. Free triiodothyronine (FT3), free thyroxin (FT4), and thyrotropin (TSH) were monitored before and after RT. The relation between the doses to thyroid gland (Dmean, Dmax, Dmin), percentage of thyroid volume receiving > 10 Gy, 20 Gy, 30 Gy, 40 Gy, and 50 Gy (V10 to V50), absolute thyroid volume, and HT were analyzed...

Inflation of the posterior and/or anterior swim bladder are processes previously demonstrated to be thyroid-hormone regulated. We investigated whether inhibition of deiodinases, which convert thyroxine (T4) to the more biologically-active form, 3,5,3'-triiodothyronine (T3), would impact swim bladder inflation. Two experiments were conducted using a model deiodinase inhibitor, iopanoic acid (IOP). First, fathead minnow embryos were exposed to 0.6, 1.9, or 6.0 mg/L or control water until 6 days post-fertilization (dpf) at which time posterior swim bladder inflation was assessed...

BACKGROUND: The growth rate often varies among individual broilers of the same breed under a common management condition. To investigate whether a variation in the growth rate is associated with a difference in hormone levels and myogenic gene expression profile in broilers, a feeding trial was conducted with 10,000 newly hatched Ross 308 chicks in a commercial production facility under standard management. At 38 d of age, 30 fast-, 30 medium-, and 30 slow-growing broilers were selected among 600 healthy male individuals...

The thyroid hormones (THs), triiodothyronine (T3) and thyroxine (T4), are very important in organism metabolism and regulate glucose utilization. Hexokinase (HK) is responsible for the first step of glycolysis, catalyzing the conversion of glucose to glucose 6-phosphate. HK has been found in different cellular compartments, and new functions have been attributed to this enzyme. The effects of hyperthyroidism on subcellular glucose phosphorylation in mouse tissues were examined. Tissues were removed, subcellular fractions isolated from eu- and hyperthyroid (T3, 0...

The thyroid functions as a regulator of cardiac function and rhythm through genomic and nongenomic actions of triiodothyronine (T3) in cardiac myocytes. Atrial fibrillation is a common complication of thyrotoxicosis. Hypothyroidism is not considered a risk factor for arrhythmias despite well-known EKG changes in this condition. This case control study was conducted to analyze the differences, if any, in the prevalence of cardiac arrhythmias between hypothyroid patients and euthyroid controls. Three hundred and four consecutive patients admitted at our medical center for a period of one year were included in the study...

Bisphenol S (BPS) is widely used as a raw material in industry, resulting in its ubiquitous distribution in natural environment, including the aqueous environment. However, the effect of BPS on the thyroid endocrine system is largely unknown. In this study, zebrafish (Danio rerio) embryos were exposed to BPS at 1, 3, 10, and 30 μg/L, from 2 h post-fertilization (hpf) to 168hpf. Bioconcentration of BPS and whole-body thyroid hormones (THs), thyroid-stimulating hormone (TSH) concentrations as well as transcriptional profiling of key genes related to the hypothalamic-pituitary-thyroid (HPT) axis were examined...

BACKGROUND: Many hypothyroid patients are not tolerant and not satisfied with levothyroxine (LT4). Older studies used large doses of both carbimazole and LT4 for Hashimoto's thyroiditis (HT), because Graves' disease (GD) and HT were considered as very closely related syndromes produced by thyroid autoimmunity. OBJECTIVE: The aim of the study was to determine the outcome after adding small doses of carbimazole to reduced doses of LT4 for patients with primary hypothyroidism, who are unable to tolerate LT4...

Research on female sexual dysfunction (FSD) is limited, especially in China, due to conservative culture and beliefs. There has been a dearth of FSD screening research in China since the optimal cutoff value of the Chinese version of the Female Sexual Function Index (CVFSFI) was determined in 2014. At the same time, the relationship between thyroid hormones and FSD has seldom been explored in Chinese women. Therefore, hospital-based research was conducted to elucidate FSD frequency and risk factors. Women who underwent a check-up at the Health Promotion Center were approached to participate and, if consented, were enrolled in the study...

This study examined the influence of environmental concentrations of Aroclor 1254 (10, 100, and 1000ng/L) on metamorphosis of Paralichthys olivaceus, and analyzed the mechanisms in relation to thyroid disruption. Results showed that 100 and 1000ng/L Aroclor 1254 delayed metamorphosis and that 1000ng/L Aroclor 1254 caused abnormal morphology. Thyroxine and triiodothyronine levels in the control group were significantly elevated at metamorphic climax, but treatment with 100 and 1000ng/L delayed the increase in thyroid hormones (THs) and retarded metamorphic processes...
