AB  - Infertility is a major global health issue, affecting approximately 9% of couples worldwide. Its prevalence increased steadily over the preceding decades, paralleling environmental and lifestyle changes. One assisted reproductive technique to overcome infertility is in vitro fertilization (IVF). The IVF procedure consists of several stages, one of which is controlled ovarian stimulation (COS) via various protocols allowing follicular recruitment and maturation in preparation for oocyte retrieval. Follicular fluid (FF) is the microenvironment in which oocytes develop during folliculogenesis, and FF information could be used to assess follicle and oocyte development and maturation stages. Nitric oxide (NO) is a component of FF that is being studied as a predictive factor of follicle maturation and egg quality and as a potential indicator of the success of COS during the IVF process. The hypothesis was that COS affects NO levels in the serum; more specifically, that NO levels in serum after COS correlate with NO levels in FF, based on literature data on the influence of female reproductive hormones on NO metabolism and data on the change in the hormonal milieu affected by COS use. Furthermore, it was hypothesized that NO levels in serum and FF after COS were related to the number of high-quality female reproductive cells obtained during IVF. Assuming that NO levels in serum after COS correlate with NO levels in FF, the central hypothesis of this study is that serum NO levels after COS could be a valuable predictor of oocyte quality and the number of high-quality female reproductive cells achieved by COS. As a result of the hypothesis, measuring NO could be a novel way to improve the efficiency of IVF treatment.

AB  - Zagađujuće materije iz otpadnih voda mogu se ukloniti različitim naprednim tehnikama prečišćavanja. Proces adsorpcije može se primeniti za uklanjanje teških metala iz otpadnih voda primenom brojnih materijala. U termoelektranama (TE) kao sporedni proizvod procesa sagorevanja uglja nastaju pepeo i šljaka. Cilj ovog rada je ispitivanje adsorpcionih svojstava pepela i šljake dodatkom cementa i kreča za uklanjanje jona teških metala (Cu2+, Zn2+, Pb2+ i Cd2+) iz vodenih rastvora. U radu su predstavljeni rezultati ispitivanja upotrebe modifikovanih oblika pepela i šljake kao adsorpcionog materijala. Najveću efikasnost uklanjanja ispitivanih jona pokazali su uzorci pepela i šljake iz TE Kostolac i TE Morava uz dodatak kreča, dok je uzorak pepela iz TE Kostolac uz dodatak cementa pokazao najmanji stepen izluživanja. Izvršena je selekcija materijala za dalja istraživanja koja obuhvataju optimizaciju procesa adsorpcije i karakterizaciju materijala.
AB  - Pollutants can be removed from wastewater by a variety advanced techniques for wastewater treatment. The adsorption process can be utilized for the removal of heavy metals from wastewater using numerous of materials. Fly ash and bottom ash are produced as a by-products of coal combustion in thermal power plants (TPP). The aim of this work has been to investigate the adsorption properties of a mixture made by adding cement and lime in fly ash and bottom ash to remove heavy metal ions (Cu2+, Zn2+, Pb2+ and  Cd2+) from aqueous solutions. This paper presents the results of a modified form of fly ash and bottom ash used as an adsorbent material. The highest removal efficiency of investigated ions has been found in samples of fly ash and bottom ash from TPP Kostolac and TPP Morava with the addition of lime, while the pattern of ash from TPP Kostolac with the addition of cement showed the smallest leaching level.    A selection of the material needs to be made in order to carry out further research that includs the optimization of the adsorption process and better char acterizing of adsorbent materials.
