Objective: Thyroid dysfunction is frequently associated with functional disturbances of the brain. We performed a meta-analysis of previous positron emission tomography and single-photon emission computed tomography studies using a coordinate-based technique of activation-likelihood estimation (ALE) to investigate the potential background of neuropsychiatric complications in patients with hypo- and hyperthyroidism.Methods: We performed a systematic searc...

Fenhexamid is one of antifungal agents used in agricultural applications, which are present at measurable amounts in fruits and vegetables. Fenhexamid has been reported to act as an anti-androgen in an androgen receptor reporter assay in engineered human breast cancer cells. Aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor, which translocates into nucleus and dimerizes with aryl hydrocarbon receptor nuclear translocator (ARNT). Although function of AR...

Background: Pituitary apoplexy (PA) is a rare, potentially life-threatening endocrine emergency, due to abrupt pituitary haemorrhage and/or infarction, usually within a pituitary adenoma. PA most commonly presents with severe headache, visual and oculomotor activity disturbances, nausea/vomiting and/or altered mental status. The outcome is variable and difficult to predict. Most proposed risk factors are hypertension (HTN), diabetes mellitus (DM), and anticoagulant treatment. ...

Gestational diabetes (GDM) occurs when beta-cell insulin secretory capacity is insufficient to meet the increased demands required to maintain normoglycemia during pregnancy. Considerable clinical evidence supports a link between depression and GDM, although underlying mechanisms are unclear. We used the unpredictable chronic mild stress (UCMS) rodent model of depression to examine the metabolic effects of depression in pregnant mice. C57BL/6J females were divided at 4-weeks-o...

Chemical contaminants from human activity are omnipresent in the environment. A great number of common industrial compounds are detected in human blood and urine. Common chemicals such as bisphenols, phthalates and parabens that can interfere with endocrine signaling are classified as endocrine disruptive compounds (EDCs). The sex steroid hormonal signaling pathway is complex and sensitive to interference, as circulating concentrations of these hormones are low. Even miniscule...

Objectives: The Danish population was previously iodine deficient with regional differences, and a mandatory iodine fortification of salt was introduced more than 20 years ago. Despite iodine fortification and frequent use of iodine-containing supplements, the iodine status in Danish pregnant women was insufficient when evaluated in 2012 (median urinary iodine concentration (UIC): 101 µg/l). From July 1, 2019 the authorities implemented a mandatory increase from 13 to 20 ...

Background: Polycystic ovary syndrome (PCOS) could be associated with increased risk of thyroid disorders. Possible associations between TSH and cardio-metabolic risk in PCOS are debated.Methods: National Register-based study on women with PCOS in Denmark. 18,476 women had a diagnosis of PCOS in the Danish National Patient Register. PCOS Odense University Hospital (OUH, N=1,146) was an embedded cohort including premenopausal women with PCOS and ...

Introduction: Adrenal Cushing due to bilateral multiple adrenal tumors known as Primary Pigmented Nodular Adrenocortical Disease (PPNAD) can be observed in the multiple neoplasia syndrome Carney Complex or as an isolated disease. In both situations germline inactivating mutations of PRKAR1A (regulatory subunit R1A of PKA) can be observed. The loss of PKA R1A results in an increased PKA activity. Comparison of the transcriptome of PPNAD and stably transfected H295R adr...

Calcium is important for physiological functioning in many tissues and is essential in mucus secretion. Previously reported, Mucin secretion is regulated predominantly by cytosolic calcium-dependent pathways. Cytosolic of calcium are regulated by calcium channels such as TRPV6, NCX1, and PMCA1. A549 cell line was treated with 10−8 M dexamethasone (DEX) and 10−6 M RU486. Subsequently, the expression of TRPV6, NCX1, and PMCA1 in A549 cell line w...

Introduction: Dexamethasone inhibits mucin secretion considering the primary option for treating acute asthma exacerbation. However, the mechanism underlying dexamethasone-induced decreased in mucosecretion is unclear. Recent studies have reported that dexamethasone exerts an inhibitory effect on mucosecretion in the lung by modulating the expression of calcium-processing genes. However, the expression of the calcium-processing genes in trachea are not examined yet. Thus, the ...
