Background: For a thorough evaluation of the pituitary gland, it is important to understand its typical structure, including the physiological differences in size and form across age groups in both males and females.Objectives: To use magnetic resonance images to examine the size, shape, and average normal volume of the normal pituitary gland at various age groups in both genders (MRI).Material and methods: 200 individuals who unde...

Objective: The aim of the study was to evaluate distribution of circulating adiponectin (AdipoQ) isoforms at pregnant women with gestational diabetes mellitus (GDM) and comparison analysis of isoform distribution changes 12 months after delivery.Design: The study was conducted on 64 pregnant women who underwent routine pre-natal tests for GDM between 24 and 28 week of gestation and 30 of them 12 months after delivery. The study group included 36 women di...

Background: Restrictive anorexia nervosa (AN) presents an adaptive appetite regulating profile including mainly high levels of ghrelin. Because this adaptive mechanism is not effective on food intake, other appetite regulating peptides need to be explored. 26RFa is a hypothalamic neuropeptide that stimulates appetite, gonadotropin release and bone metabolism. The aim of the current study was to evaluate circadian levels of 26RFa in AN patients compared with healthy subjects, o...

Introduction: Nodular goiter is clinically recognizable restricted structure changes of the thyroid gland. FNA is the first line diagnostic test for an enlarged thyroid gland. TSH is known as a thyroid growth factor, but the pathogenic role of this hormone in thyroid oncogenesis is unclear.Objective: The aim of this study is to analyze the relationship between elevated serum TSH concentrations and thyroid malignancies in patients with nodular thyroid goi...

Introduction: Iodine deficiency disorders are considered as the most wide spread non infectious diseases of the humanity. Uzbekistan is in the zone of the severe iodine deficiency (ID). According to epidemiologic studies performed in 1998 endemic goiter (EG) prevalence was 80% whereas urinary iodine was <10 μg/l. In May, 2007 Uzbek government legislated the Salt Iodization Law and in 2009 ID evaluation was performed in the Uzbekistan using sentinel approach.<p cla...

Turner syndrome (TS) is associated with more frequent ophthalmic morbidity.The goal: To investigate the prevalence and severity of ophthalmic problems in patients with TS diagnosis established on a detailed karyotype analysis.Patients and method: 73 girls with TS aged 2–30 (mean 14.34±6.39) were involved in the study. 45,X monosomy was found in 57.8% of them, different mosaic pattern in 33.8% and structural aberration in ...

Nadir growth hormone (GH) levels after oral glucose tolerance test (OGTT) as well as random insulin-like growth-factor I (IGF-I) levels, given as multiples of the upper limit of normal [xULN], were used to evaluate biochemical activitiy of acromegalic patients. The development of new, more sensitive GH assays makes it necessary to reevaluate the cut off values of the GH nadir after OGTT.In a cross sectional study, we evaluated nadir GH concentrations dur...

Background: In Graves’ disease, immune cellular mechanisms and cytokine release, as well as auto-antibody production found in the serum, most likely contribute to the development of thyroid eye disease (TED). Biosynthesis of neopterin is closely associated with activation of the cellular immune system and could be a valuable marker of the severity of the disease.Objectives: To assess whether serum neopterin concentrations in patients with TED are a ...

Background: An “empty sella” is characterised by a sella turcica filled with cerebrospinal fluid. It is called primary when the empty sella is not linked to any pathological process of the pituitary itself. The prevalence of empty sella has been reported in up to 38% of imaging studies. Some patients may present with endocrine, neurological and ophthalmological symptoms due to the aberrant anatomy of the sellar region. The aim of this study was to analyse clinical pr...

VEGF is an endothelial-cell specific mitogen and is a critical regulator of developmental and reproductive angiogenesis. VEGF165 is the most abundant isoform, with the N-terminal 110 aa domain containing the receptor binding site and the C-terminal 55 aa domain containing a heparin-binding site. The activity of the molecule is mediated through its interaction with two main receptors, VEGFR-1 and VEGFR-2, the binding to which is modulated by both cell surface-associated glycosa...
