Excess fructose consumption is associated with the development of type 2 diabetes and obesity. However, the impact of fructose intake on maternal and fetal lipid metabolism during pregnancy is not known. The aim of this study was to examine whether maternal fructose intake during pregnancy would affect fetal and maternal hepatic lipid metabolism. Pregnant Wistar rats were randomly divided into untreated...
Most studies of combination therapy with teriparatide and a bisphosphonate have not shown greater efficacy over monotherapy. The bisphosphonate risedronate, has not been studied in this context. The purpose of this proof-of-concept study was to assess whether combination risedronate and teriparatide increases bone mineral density (BMD) more than monotherapy with either drug alone. This was a randomized,...
Both overt (OHT) and subclinical hypothyroid (SHT) disorders have been found to be associated with increased oxidative stress (OXS). Excess thyrotropin [thyroid stimulating hormone (TSH)] is known to directly produce OXS. Increased lipid peroxidation is known to facilitate protein carbonylation. However, the associations between lipid and protein oxidation and elevated TSH levels have not been studied...
Acromegaly is associated with a variety of cardiovascular disturbances such as left ventricular hypertrophy, diastolic cardiac dysfunction, and hypertension. Left ventricular (LV) dyssynchrony means the impairment of synchronicity and is defined as the loss of the simultaneous peak contraction of corresponding cardiac segments. The objective of this study was to investigate whether acromegalic patients...
Leptin (from the Greek word “lepto’’ meaning “thin”) is a 167-amino acid peptide hormone encoded by the obesity (ob) gene and secreted by white adipocytes. Blood leptin concentrations are increased in obese individuals. Leptin is a satiety hormone that provides negative feedback to the hypothalamus, controlling appetite and energy expenditure. Leptin binds to presynaptic GABAergic neurons to produce...
Metabolic syndrome (MetS) is associated with an increased risk of major cardiovascular events. In women, increased uric acid (UA) levels are associated with MetS and its components. High-sensitivity C-reactive protein (hsCRP) levels are also associated with MetS, and hsCRP levels could be modulated by UA. We investigated whether combining UA and hsCRP levels are independently associated with MetS...
Intracranial tumors of different histologic types infrequently affect patients with pituitary adenomas and no history of head irradiation. The association with craniopharyngioma is extremely rare. Aims of this paper are: (1) to provide a critical literature review of typical features of pituitary adenoma presenting in association with craniopharyngioma; (2) to describe the first documented (clinically,...
The aim of this study was to evaluate the effect of Cabergoline on insulin sensitivity, inflammatory markers, and carotid intima media thickness in prolactinoma patients. Twenty-one female, newly diagnosed patients with prolactinoma were included in the study. None of the patients were treated previously. Cabergoline was given as treatment, starting with 0.5 mg/day and tapered necessarily. Blood samples...
The aim of this study was to explore whether IL-7 participates in the pathogenesis of Graves’ ophthalmopathy (GO). This was a prospective study. 20 GO patients (40 eyes) and 20 healthy volunteers (40 eyes) were recruited. The tear concentration of IL-7 was measured using ELISA assay. IL-7 expression in orbital tissues was evaluated by immunohistochemistry. Patients with inactive GO had the highest...
Immunosuppressive lymphocytes, such as regulatory T cells (Tregs) and plasmacytoid dendritic cells (pDCs), play crucial roles in tumor escape. To investigate the roles of Tregs and pDCs in papillary thyroid cancer (PTC) plus multinodular non-toxic goiter (MNG), thyroid tissue and blood samples from 30 patients with PTC plus MNG and 30 MNG alone were analyzed for CD4+ T cell, CD8+ T cell, FoxP3+ Treg,...
Heterozygous loss-of-function mutations in NEUROD1 have been identified as a very rare cause of maturity-onset diabetes of the young and neonatal diabetes. Previous studies showed that a common A45T variant located in NEUROD1 was inconsistently associated with type 2 diabetes mellitus (T2DM) in different ethnic populations. This study aimed to evaluate the contribution of variant A45T in the genetic...
The concept that extracellular vesicles may act as paracrine/endocrine effectors is based on the evidence that they are able to transport bioactive molecules between cells, either within a defined microenvironment or remotely, by entering the biologic fluids. Extracellular vesicles, including exosomes and microvesicles, may deliver lipids and various functional transcripts, released from the cell...
Diagnosis of dysglycemic states is likely delayed as current diagnostic criteria apply absolute threshold values to a process that is continuous. The importance of this relates to forestalling opportunities for earlier diagnosis when prevention and reversibility are more likely to occur by preventing further β cell dysfunction. Although the optimal method for earlier identification of individuals...
Growth hormone (GH) and prolactin share similarities in structure and function. We have previously shown that women with congenital isolated GH deficiency (IGHD) caused by a homozygous mutation in the GHRH receptor gene (GHRHR) (MUT/MUT) have a short reproductive life, with anticipated climacteric. At climacteric, they have lower prolactin levels than normal controls (N/N). Because they are able to...
Mutations in the 11β-hydroxylase (CYP11B1) gene are the second leading cause of congenital adrenal hyperplasia (CAH), an autosomal recessive disorder characterized by adrenal insufficiency, virilization of female external genitalia, and hypertension with or without hypokalemic alkalosis. Molecular analysis of CYP11B1 gene in CAH patients with 11β-hydroxylase deficiency was performed in this study...
