Determination of 7,12-dimethylbenz[a]anthracene in orally treated rats by high-performance liquid chromatography and transfer stripping voltammetry
Yardım, Yavuz; Levent, Abdulkadir; Ekin, Suat; Keskin, Ertuğrul; Oto, Gökhan; Şentürk, Zühre (Bentham, 2012-06)A number of polycyclic aromatic hydrocarbons (PAHs) have been shown to be toxicants, and induce carcinogenic and immunotoxic effects. As a model PAH agent, 7,12-dimethylbenz[a]anthracene (DMBA) was the strongest one tested ... -
Determination of trace metal and mineral levels in the tobacco and cigarette samples using by FASS
Levent, Abdulkadir; Yardım, Yavuz; Demir, Cengiz (Chemical Society of Pakistan, 2013-04)Cigarettes and tobacco products are consumed in large amounts by human beings in the world. Also, tobacco is one of the most important agricultural products in Turkey. The accumulation of heavy metals in tobacco leaves in ... -
Electrochemical performance of boron-doped diamond electrode in surfactant-containing media for ambroxol determination
Levent, Abdulkadir; Yardım, Yavuz; Şentürk, Zühre (Elsevier, 2014-07-17)A novel application of boron-doped diamond electrode is introduced for the determination of ambroxol, a potential antioxidant drug belonging to the expectorant class. The electrochemical oxidation of ambroxol was first ... -
Electrooxidation of thiourea and its square-wave voltammetric determination using pencil graphite electrode
Levent, Abdulkadir; Keskin, Ertuğrul; Yardım, Yavuz; Şentürk, Zühre (Walter de Gruyter, 2011-04-01)The electrochemical properties of thiourea (TU) were investigated in pH range 2.0-12.0 by cyclic and square-wave voltammetry. The compound was irreversibly oxidized at a pencil graphite electrode in one or two oxidation ... -
Graphene/Nafion composite film modified glassy carbon electrode for simultaneous determination of paracetamol, aspirin and caffeine in pharmaceutical formulations
Yiğit, Aydın; Yardım, Yavuz; Çelebi, Metin; Levent, Abdulkadir; Şentürk, Zühre (ScienceDirect, 2016-05-16)A graphene-Nafion compositefilm was fabricated on the glassy carbon electrode (GR-NF/GCE), and usedfor simultaneous determination of paracetamol (PAR), aspirin (ASA) and caffeine (CAF). The electro-chemical behaviors of ... -
Protective effect of Hypericum perforatum L. on serum and hair trace elements in rats 7,12-dimethylbenz[a]anthracene-induced oxidative stress
Ekin, Suat; Yardım, Yavuz; Oto, Gökhan; Levent, Abdulkadir; Özgökçe, Fevzi; Kusman, Tuba (Elsevier, 2012-02-08)The study was designed to assess the effect of Hypericum perforatum L. (H.P) on serum and hair trace elements and mineral levels, oral administration of 7,12-dimethylbenz[a]anthracene (DMBA) induced oxidative stress in ... -
Sensitive voltammetric determination of testosterone in pharmaceuticals and human urine using a glassy carbon electrode in the presence of cationic surfactant
Levent, Abdulkadir; Altun, Ahmet; Yardım, Yavuz; Şentürk, Zühre (Elsevier, 2014-05-10)In this work, the electrochemical investigation of testosterone, a steroid hormone from the androgen group, was carried out in aqueous and aqueous/surfactant solutions using a glassy carbon (GC) electrode. In cyclic ... -
Voltammetric behavior of benzo[a]pyrene at boron-doped diamond electrode: A study of its determination by adsorptive transfer stripping voltammetry based on the enhancement effect of anionic surfactant, sodium dodecylsulfate
Yardım, Yavuz; Keskin, Ertuğrul; Levent, Abdulkadir; Şentürk, Zühre (Elsevier, 2011-07-15)Benzo[a]pyrene (BaP), a member of the polycyclic aromatic hydrocarbon (PAH) class, is one of the most potent PAH carcinogens. The electrochemical oxidation of BaP was first studied by cyclic voltammetry at the boron-doped ... -
