Mortality prediction with lactate and lactate dehydrogenase
(Springer International Publishing Ag, 2015)It has been proved in many studies that Lactate and Lactate dehydrogenase (LDH) are associated with mortality. in this study lactate test values of inpatients were analyzed with Support Vector Machines (SVM) to identify ... -
N-acetylcysteine ameliorates 5-fluorouracil-induced ovarian injury in rats
(Marmara Üniversitesi, 2023)Objective: Although 5-fluorouracil (5-FU) is one of the most commonly used chemotherapeutics worldwide, it has been shown that 5-FU administration can cause reproductive toxicity in recent years. N-acetylcysteine (NAC) is ... -
Nano-sized and microporous palladium catalyst supported on modified chitosan/cigarette butt composite for treatment of environmental contaminants
(Elsevier, 2022)This study reports a versatile process for the fabrication of a microporous heterogeneous palladium nanocatalyst on a novel spherical, biodegradable, and chemically/physically resistant catalyst support consisting of ... -
Network analysis of international export pattern
(Springer, 2022)There is a relationship between the trade flows of the countries and their economic growth potential and development. One way to analyze the trade flows of countries with each other is the use of network analysis techniques. ... -
A new activated carbon-supported Pd-ZnO catalyst for Heck Cross-coupling reactions
(Elsevier, 2023)In this work, to develop catalysts for Heck-type coupling reactions, a hybrid ZnO-Pd nanocatalyst was fabricated on activated carbon sourced from polymer debris. Such techniques as transmission electron microscopy (TEM), ... -
New Chromenylium-cyanine based dual channel chemosensors for copper and hypochlorite sensing
