Background: We investigated the frequency for diagnosis of Hashimoto’s thyroiditis (HT) in obstructive sleep apnea (OSA) patients, based on rising interest in potential links of OSA’s pathogenesis with impaired auto-immune mechanisms.Design and methods: Polysomnography was performed to 245 euthyroid eligible subjects consecutively. Study population divided according to apnea-hypopnea index (AHI) as control (n=59, AHI<5), mild OSA (<i...

Objective: The spontaneously hypertensive stroke prone rat (SHRSP) is a model of insulin resistance and dyslipidemia. Feeding a 60% fructose diet exaggerates these phenotypes. It has been suggested that the Y chromosome may influence lipid levels in the spontaneously hypertensive rat (SHR). Therefore we examined the effects of Y chromosome on lipid phenotypes in the SHRSP after fructose feeding.Design and Methods: The S.W. Y consomic strain was construc...

Objective: To investigate osteoporosis features in elder patients in Moscow populationMaterials and Methods: It was a retrospective study, during which we analyzed the data of 192 outpatients admitted to our Centre. In the focus of our attention was patients’ past medical history and T-criteria values assessed by DEXA-scan. The statistical analysis was performed using Prism 8 Version 8.0.1 (145). Statistically significant were differences with P...

Adrenal incidentalomas (AI) are a common finding in patients studied by abdominal imaging and approximately 9–17% is found bilaterally. So far, the potential role of hypothalomo-pituitary adrenal (HPA) axis dysregulation in the pathogenesis of AI, especially of those found bilaterally, has not been addressed. The DEXA-CRH test has been previously used to detect dysregulation of the HPA axis; herein, it was used to assess ACTH and cortisol responses in a large group of pat...

Aim: In our study, we aimed to evaluate the cytologic findings of the thyroid nodules, in which macrocalcification is determined with ultrasonography.Method: We evaluated retrospectively 907 nodules of 269 patients, who have nodular or multinodular goiter and have macrocalcification at least in one nodule. The same patients’ nodules that don’t have macrocalcification are taken into the control group. Patient’s thyroid function tests, ultra...

Aim: To compare gender frequency of leptin receptor gene (LEPR) genotype rates and leptinemia levels in overweight children.Materials and methods: Three hundred children with adiposity were investigated (divided into groups: prepubertal (1st) m/f n=51/50, early pubertal (2nd) n=49/51, late pubertal (3d) n=50/49). 80 girls and 89 boys with obesity and 90 lean girls and 48 lean boys (control) were genotyped in 6 exon of LEPR gene (Q223...

Background: The hypothalamus is a critical area of the brain involved in the regulation of appetite. Cerebellin1 (Cbln1) is a highly conserved 16 amino acid neuropeptide. High levels of Cbln1 mRNA expression are found in specific hypothalamic areas involved in appetite regulation.Aim: To examine the effects of Cbln1 on food intake in rodents.Methods: 1. Ad libitum fed rats were injected intracerebroventricularly (ICV) with Cbln1 (1...

Introduction: The incidence of Type 1 diabetes (T1D) is rising. The effect of increasing BMI in children has been proposed. A relationship between age of diagnosis of T1D and BMI SDS has been reported by some but not confirmed in all studies. We propose age of diagnosis and autoantibody status may be influenced by BMI and inherited factors relating to BMI and insulin resistance.Methods: BMI SDS was calculated in 230 children with newly diagnosed T1D, 4&#...

Energy balance is controlled by the arcuate nucleus through integration of peripheral hormonal signals such as leptin, ghrelin, peptide YY (PYY) and glucagon like peptide 1 (GLP-1). The commonest reason for young women in the developed world to be underweight is restrictive anorexia nervosa (AN). Constitutionally thinness (CT) has been described in young women who satisfies the WHO definition for moderate to severe underweight (BMI 13–16.9 kg/m2). CT women have...

Objective: The spontaneously hypertensive stroke prone rat (SHRSP) is a model of insulin resistance and dyslipidemia. Feeding a 60% fructose diet exaggerates these phenotypes. The Y chromosome may influence lipid levels in the spontaneously hypertensive rat (SHR). Therefore we aim to characterise the metabolic syndrome using in vivo and dyslipidemic phenotpyes in the SHRSP and examine the contribution of the Y chromosome.Methods: SHRSP and WKY Y consomic strains (SP...
