Background and hypothesis: Mitochondrial disorders are multisystemic conditions associated with sensorineural hearing loss, encephalomyopathy, lactic acidosis, and non-autoimmune diabetes. The majority of molecular etiologies involve mutations in the genes encoding the oxidative phosphorylation system's components. Superoxide generation is significantly increased and causes oxidative damage in the affected tissues in these disorders. The establishment of ...

The Relationship Between Leptin, Kisspeptin, Irisin, Myostatin and Omentin Levels and Fat Tissue at Puberty

Başak Polat Zeliha , Orbak Zerrin , Doneray Hakan , Ozturk Nurinnisa

Introduction: The hypothalamo-pituitary system is activated as puberty begins and GnRH release occurs as well as the synthesis of many hormones. These hormones cause changes on muscle development, body fat distribution. In this study, changes in miyostatin, irisin, kisspeptin, omentin and leptin levels and the relationship of these changes with physical properties and fat tissue were investigated.Material and Method: A t...

Can Different Diets (High Fat and High Fructose Diet) Affect Insulin Resistance, Tissue Advanced Glycation End Product Levels in Rats' Pancreas

Orbak Zerrin , Demirci Tuba , Ozturk Nurinnisa , Alaca Raziye

Introduction & Objectives: High consumption of processed foods rich in fat and sugar are associated with the increasing prevalence of metabolic disturbances like obesity, insülin resistance, dyslipidemia, type 2 diabetes mellitus. In the present study, we aimed to investigate the relationship between advanced glycation end products and metabolic disorders such as insulin resistance caused by high fructose and high-fat diet, and also examine histologic...

The Effect of Fibroblast Growth Factor 23 on Serum Phosphorus Level in Children with Diabetic Ketoacidosis

Doneray Hakan , Ozay Mustafa , Ozden Ayse , Ozturk Nurinnisa , Orbak Zerrin

Aim: The pathophysiology of developing hypophosphatemia in children with diabetic ketoacidosis (DKA) has not been sufficiently elucidated. Fibroblast Growth Factor 23 (FGF23) is a hormone that causes phosphate excretion from the kidneys. The increase of FGF23 in children with DKA may explain the pathophysiology of hypophosphatemia in these children. The aim of our study was to investigate the effect of serum FGF23 on serum phosphorus level in children with DKA...

Immunogenetics and Clinical Characteristics of Patients with the Most Common Organ-Specific Autoimmune Diseases: Evaluation in Respect of Gender and Autoimmunity

Karaoglan Murat , Keskin Mehmet , Keskin Ozlem , Ozturk Sibel

Background: Most of autoimmune disease such as type 1 diabetes (T1DM), autoimmune thyroiditis (AIT) and coeliac disease (CD) often coexist in the same patient. Although there are a lot of number of studies on autoimmunity against the thyroid glands and small bowel in patients with type 1 diabetes, little is known about pancreatic β-cell immunity in patients with AIT and CD.Objective and hypotheses: We studied autoimmune markers in children patients ...

Coexistence of Unusual and Distinctive İnitial Clinical Manifestations of Systemic Lupus Erythematosus (SLE): a Child Case Presentation and Evaluation of Polyglandular Autoimmune Syndrome in SLE

Karaoglan Murat , Keskin Mehmet , Ozturk Sibel , Kesin Ozlem

Background: Involvement of multiple spesific endocrine organs in systemic lupus erythematosus (SLE), as initial manifestations, are quite rare. These manifestations can appear singly or combined. But they have been usually reported singly. We report a child case who coexists many of rare clinical features of SLE at the same time at onset.Objective and hypotheses: Polyglanduler autoimmune syndrome may be a part of SLE. Coexistence of many polyglanduler au...

Effect of cholecalciferol treatment on serum FGF-23, vitamin D-binding globulin and α-klotho levels in children with vitamin D deficiency

Tosun Ilker , Orbak Zerrin , Doneray Hakan , Ozturk Nurinnisa ,

Introduction and Aim: FGF-23 is a hormone that works by inhibiting phosphorus reabsorption in kidneys, and systematic regulation of phosphate homeostasis by FGF23 depends on the activity of the membrane protein Klotho. It affects the active vitamin level according to the bioactive free vitamin hypothesis, which binds DVBP to vitamin D and prolongs its half-life. In this study, it was aimed to investigate 1.25 (OH) Vitamin D, Vitamin D Binding Protein, FGF-23 a...

Background: Hereditary hypophosphatemic rickets with hypercalciuria(HHRH; OMIM: 241530) is a rare autosomal recessive disorder,which is the result of loss-of-function mutations in the sodium-phosphate-cotransporter NPT2c.This disorder is characterized by renal phosphate(Pi) wasting,hypercalciuria,increased 1,25 (OH)2-D levels and decreased parathormone(PTH) levels.Here we report the clinical features of two siblings with HHRH,confirmed with molecula...
