We report a case of 11-year-old girl with growth retardation and 46, XX, Xq27-qter deletion. The endocrinologic evaluation revealed growth hormone deficiency. In karyotype analysis  46, XX, Xq27-qter deletion was determined. The deletion of terminal region of chromosome 27 is most commonly being detected during the evaluation of infertility, premature ovarian insufficiency or in screening for fragile X carrier status. To our knowledge, this is the first reported case with 46, XX, Xq27-qter deletion and growth hormone deficiency...

BACKGROUND: Spinal vascular malformations as a group are rare entities and coexistence of spinal arteriovenous malformation in or around the spinal dysraphism is extremely rare. CASE DESCRIPTION: Herein, we report two cases of combined spinal dysraphism and vascular malformations of the spinal cord. The first case is an arteriovenous malformation located in a filum terminale lipoma fed by the artery of filum terminale. This case was managed by multiple endovascular embolizations followed by surgery...

In this study, it was aimed to examine the antioxidant and antihepatotoxic effects of hydroxyurea derivative Schiff bases on serum biochemical parameters (AST, ALT, LDH, urea, creatinine and total bilirubin) and antioxidant parameters (SOD, CAT, GPx, MDA). In this study, a total of 49 adult male Wistar rats was examined and they were divided into 7 equal groups. DMSO, which is diluted only with corn oil, was administered to control group. 25 mg / kg ligand, 25 mg / kg Schiff base - manganese, 25 mg / kg Schiff base-copper, 25 mg / kg Schiff base - zinc, 25 mg / kg Schiff base - nickel, 25 mg / kg Schiff base - cobalt complexes were administered to rats of experimental group subcutaneously for 15 days with three-day intervals throughout the test process...

Orexigenic and anorexigenic peptides, especially agouti-related protein (AgRP) and leptin, play important roles in the regulation of energy homeostasis in bipolar disorder. AgRP regulates energy metabolism by increasing appetite and decreasing energy expenditure. The resting energy expenditures of patients with manic bipolar disorder are higher than those of controls. Due to the effects of AgRP on energy expenditure and the increased physical activity of manic patients, we hypothesised that serum AgRP levels may be lower in manic patients than in euthymic patients and controls...

Background: The nicotine may generate a influence on bone repair and longevity of dental implants. This fact makes studies to improve the surface of the implants are constantly conducted. This study aimed to evaluate the influence of subcutaneous nicotine injection in the osseointegration process on different implant surfaces, through histomorphometric analysis. Material and Methods: Therefore, twenty-two male rabbits were randomly distributed into two groups according to the subcutaneous injections: (1) nicotine, 3 mg/day/kg and (2) 0...

Very recently, neuromodulation through deep brain stimulation (DBS) has appeared as a new surgical procedure in the treatment of some types of dementia and epilepsy. The mammillothalamic and the mammillotegmental tracts are involved among the new targets. To our knowledge, a review article focused specifically on these mammillary body efferents is lacking in the medical literature. Their contribution to memory is, regrettably, often overlooked. There is evidence that mammillary bodies can contribute to memory independently from hippocampal formation, but the mechanism is not yet known...

Glucagon like peptide-1 (GLP-1) is an incretine hormon that has modulating effects on insulin release. GLP-1 and receptors for GLP-1 are widely expressed throughout the body including brain.The expression of GLP-1 receptors is very specific to large neurons in hippocampus, neocortex and cerebellum. GLP-1 receptor stimulation enhances glucose-dependent insulin secretion and lowers blood glucose in type 2 diabetes mellitus. Studies on adipobiology of neurotrophins have focused on nerve growth factor (NGF) as an example of adipose-derived neurotrophins...

OBJECTIVE: The aim of this study was to evaluate the functional results, complications, and morbidity and mortality rates in patients with end-stage chronic renal failure (ESCRF) with collum femoris fractures who were treated with hemiarthroplasty. METHODS: From 2005 to 2013, patients with ESCRF admitted to our hospital with collum femoris fracture and treated with hemiarthroplasty were retrospectively evaluated, and 44 hips in 42 patients were included in the study...

Human respiratory syncytial virus (HRSV) is most important viral respiratory pathogen of acute lower respiratory tract infections in infants and young children worldwide. The circulating pattern and genetic characteristics in the HRSV attachment glycoprotein gene was investigated in Turkey during 6 consecutive seasons from 2009 to 2015. HRSVA was dominant in the all epidemic seasons except 2011-2012 season. Partial sequences of the HVR2 region of the G gene of 479 HRSVA and 135 HRSVB were obtained. Most Turkish strains belonged to NA1, ON1 and BA9, which were the predominant genotypes circulating worldwide...

INTRODUCTION: Rupture of the Achilles' tendon is a common injury occurring particularly in middle-aged men due to sports trauma. Operative treatment is preferred generally due to lower risk of re-rupture. Possible complications of the operation include suture granulomas. Suture granulomas might represent a foreign body reaction, which itself is the end-stage response of the inflammatory wound-healing process to biomaterials. It may occur with both absorbable and non-absorbable suture materials such as silk in our case...

Introduction: Chronic obstructive pulmonary diseases are common causes of disease in the community and account for considerable percent of the caseload in primary health care facilities. For this reason, it is important to question and improve the knowledge of primary health care physicians. This study is designed to assess the level of knowledge for bronchial asthma and COPD of the primary healthcare physicians, both before and immediately after an educational course structured in the context of GARD Chronic Airway Diseases National Control Program...

PURPOSE: Flow diverters are increasingly used in the treatment of complex and giant intracranial aneurysms. However, they are associated with complications like late aneurysmal rupture. Additionally, flow diverters show focal structural decrease in luminal diameter without any intimal hyperplasia. This resembles a "fish mouth" when viewed en face. In this pilot study, we tested the hypothesis of a possible association between flow diverter fish-mouthing and delayed-type hypersensitivity to its metal constituents...

The mycobacterial phosphoglycosyltransferase WecA, which initiates arabinogalactan biosynthesis in Mycobacterium tuberculosis, has been proposed as a target of the caprazamycin derivative CPZEN-45, a preclinical drug candidate for the treatment of tuberculosis. In this report, we describe the functional characterization of mycobacterial WecA and confirm the essentiality of its encoding gene in M. tuberculosis by demonstrating that the transcriptional silencing of wecA is bactericidal in vitro and in macrophages...

INTRODUCTION: We aimed to explore potential cytokines involved in the malignant middle cerebral artery infarction (MMI) and elucidate their underlying regulatory mechanisms. METHODS: We first developed a cytokine profile by Quantibody(®) Human Cytokine Antibody Array7000 using serum samples from eight patients with MMI and eight patients with non-acute cerebral infarction (NACI). The differentially expressed cytokines were then identified in patients with MMI using two-tailed Student's t-test and Fisher's Exact Test compared with patients with NACI...
