Introduction: Adolescence is a crucial period for linear growth, and sports training during this time may have positive or negative effects on some physiological processes as growth. The purpose of this study was to evaluate the effect of intense training during somatic growth on the onset of puberty and growth development in adolescent wrestlers.Description of methods/design: Fifty adolescent male wrestlers and 21 sedentary healthy male controls aged 13...

Introduction: The telephone endocrine clinic (TEC) was established as an adjunct to the face-to-face endocrine clinic to follow and monitor the progress in a selected group of patients after they were seen in main endocrine clinics. This model of care has been tried successfully in other specialities but not as widespread in endocrinology. We audited the effectiveness of TEC and patient satisfaction. Methods: A retrospective analysis of records of all patients contacted in TEC...

Objective: We aimed to examine sexual dysfunction frequency and relationship between sexual dysfunction and androgen level in polycystic ovary syndrome.Patients and methods: Twenty-five PCOS patients were recruited from the outpatient clinics of the Division of Endocrinology in the Department of Internal Medicine and outpatient clinics of the Department Obstetrics and Gynecology at the Cerrahpasa Medical Faculty. Twenty-five healthy volunteer age and sex...

We present two cases because 17OHD is the rare cause of congenital adrenal hyperplasia (1%) and our patients are first cousins (their fathers are brothers). Genetically female patients with congenital adrenal hyperplasia due to 17-α hydroxylase enzyme deficiency (17OHD) represent with sexual infantilism, hypertension and genetically male patients represent with male pseudohermaphroditisim, hypertension at pubertal age. The cousins applied for primer amenorrhea and hyperte...

Idiopathic hypoparathyroidism (IHP) is an uncommon disease in which soft tissue calcifications may be seen. We report a case with IHP with asymptomatic hypocalcemia and features of ankylosing spondylitis (AS).Case: A 58-year-old male patient was referred to our department due to incidentally discovered hypocalcemia when admitted with blurred speech, gait and posture abnormalities. He had had a generalized convulsion 19 years ago. On physical examination,...

Plant growth factors are used commonly in agriculture. The effect of these factors on human health is unknown. Gibberellins are the most commonly used growth factors that have the structure of Diterpenoid acid. One of the gibberellins (GA3) induces tumor formation in mice but the mechanism of action is not known. We here examined changes in levels of GH and IGF-1 and examined whether there is a correlation between growth factors’ levels and weight changes.<p class="ab...

Objectives: Mountain biking has become increasingly popular worldwide. Mountain bikes, are a common source of significant injuries including chronic overuse injuries affecting the genitourinary tract. Erectile dysfunction and infertility are some of the reported urogenital problems in male riders. Our aim was to evaluate the testicular function in male mountain bikers.Methods: Thirty male professional mountain bikers with a mean age of 23.4±2.5 year...

Background: Parathyroid hormone-related protein (PTHrP) was discovered as a tumor product. It is also one of the complex epithelial and mesenchymal interaction signal mediator in breast development. An increase in the prevalence of malignancy in patients with Klinefelter’s syndrome, but not in patients with idiopathic gynecomastia has been previously reported. PTHrP may play a critical role in the development or progression of breast cancer.Aim: We ...

Context: FABP4 (adipocyte-specific fatty acid-binding protein 4, also known as aP2) is a cytoplasmic lipid chaperon involved in lipid metabolism, glucose homeostasis, and the regulation of inflammatory response. Its expression is limited to adipocytes, macrophages, skeletal muscle, and bronchial epithelia. Recently, a polymorphic allele of the aP2 promoter (−87T→C) has been shown to be associated with decreased FABP4 expression in fat tissue, lowered triglyc...

Lipid peroxidation is linked with several metabolic diseases. Lipid peroxidation causes cellular damage through reactive aldehyde species such as 4-hydroxyonenal (4-HNE). The exact mechanism(s) by which 4-HNE causes damage in the intravascular compartment is not exactly known. Using an in vitro system, we investigated the damage induced by 4-HNE on the blood by measuring protein carbonyl groups and thiobarbituric acid reactive substances (TBARS) following 4-HNE treatm...
