Plasma CA-125 level is related to both sides of the heart: A retrospective analysis
(ELSEVIER IRELAND LTD, 2011)Objective: CA-125 is an old marker, recently shown to be associated with systolic heart failure. We aimed to search for factors influencing its plasma level. Design: 430 patients with one available CA-125 level were ... -
The parameter extraction of the thermally annealed Schottky barrier diode using the modified artificial bee colony
(SPRINGER, 2013)In this paper, a new method based on the modified artificial bee colony (MABC) algorithm to determine the main characteristic parameters of the Schottky barrier diode such as barrier height, ideality factor and series ... -
Role of Modification of Natural Zeolite in Removal of Arsenic from Aqueous Solutions
(SLOVENSKO KEMIJSKO DRUSTVO, 2018)The adsorption of arsenic from aqueous solution onto natural and modified zeolites was investigated. The natural zeolites were modified by ion-exchange (NH4NO3) and addition of aluminum (Al-2(SO4)(3)). The natural and ... -

(VERLAG HANS HUBER, 2003)Aim: The aim of this study was to determine the relationship,between nutrition, gestational age, and birth weight, and serum insulin-like growth factor I (IGF-1) levels in newborns, Method: The first study group consisted ... -
Bone mineral density in familial Mediterranean fever
(SPRINGER HEIDELBERG, 2012)The aim of this study was to evaluate the bone mineral density (BMD) in familial Mediterranean fever (FMF) and to search the effects of genetic factors, family history of FMF and types of clinical attacks on BMD. Forty-four ... -
Endothelial Nitric Oxide Synthase Gene [G894T] polymorphism as a possible risk factor in aneurysmal subarachnoid haemorrhage
(SPRINGER WIEN, 2008)Background. The exact aetiology, growth and rupture of intracranial aneurysms is unclear. In this study we investigated a possible association between intracranial aneurysm rupture and polymorphism of the endothelial nitric ... -
