This study aims to evaluate the black bullhead Ameiurus melas, an invasive alien fish (IAF) in Serbia, as a bioindicator organism and assess the safety of natural and aquaculture specimens for human consumption. A set of biomarkers was analysed to assess the bioindicator potential at a site exposed to agricultural activities. The genotoxic response...

This study aimed to determine concentrations of 29 elements in the gills and liver as well as biomarker response in gills, liver, and blood of European chub from Pek River (exposed to long-term mining activities), and to compare these findings with individuals from Ibar River (influenced by emission of treated municipal wastewater) and Kruščica res...

In this study early signs of deterioration of the ecosystem in the Boka Kotorska Bay were assessed by applying an active biomonitoring approach for the first time in coastal area of Montenegro. Gilthead sea bream (Sparus aurata), commercially farmed in the Bay, was used as a bioindicator. Specimens were translocated from an aquaculture farm to more...

In response to the global rise in antibiotic resistance and the prevalence of bacterial biofilm-related infections, the antibacterial efficacy of methanolic, ethanolic, and aqueous extracts of 18 Lamiaceae plants from Serbia was evaluated. The total coumarins and triterpenes were detected spectrophotometrically, while a microdilution assay measured...

One of the most severe threats to the Danube River course through Serbia is the direct discharge of untreated wastewater. In biomonitoring studies, faecal indicator bacteria are used to reveal the presence of untreated communal wastewater, while biomarker responses in indigenous biota serve as a useful indicator of their harmful potential. The obje...

Environmental studies which aim to assess the ecological impact of chemical and other types of pollution should employ a complex weight-of-evidence approach with multiple lines of evidence (LoEs). This study focused on in situ genotoxicological methods such as the comet and micronucleus assays and randomly amplified polymorphic DNA analysis as one...

In this study, the possible ‘vector effect’ within the exposure of Mediterranean mussels (Mytilus galloprovincialis) to polystyrene microplastics with adsorbed fluoranthene was investigated by applying the multibiomarker approach. The major focus was placed on genotoxicological endpoints as to our knowledge there are no literature data on the genot...

TRACK 1-lecular weight pattern of proteins. CONCLUSIONS: The results in term of digestosomatic index, specific activities of digestive enzymes, and chyme biochemical characteristics physiologically responded with post-prandial changes in bigfin reef squids. The food transited rapidly and was maximally digested by enzymes within 0.5 to 4 h after fee...

This study was designed to evaluate the genoprotective, antigenotoxic, as well as antitumor potential of methanolic, ethanolic, and aqueous extracts of Melissa officinalis, Mentha × piperita, Ocimum basilicum, Rosmarinus officinalis, Salvia officinalis, and Satureja montana (Lamiaceae), in different model systems. The polyphenols in these extracts...

Recently, cancer research has focused on the search for new and more effective antitumor agents of natural origin that can activate multiple defence mechanisms and selectively damage transformed cells. The goal of this research was to assess different antitumor mechanisms of ethanolic extracts of 18 Lamiaceae species traditionally used in Serbian f...

This research was aimed to assess the potential of Glechoma hederacea, Hyssopus officinalis, Lavandula angustifolia, Leonurus cardiaca, Marrubium vulgare and Sideritis scardica (Lamiaceae) methanolic, ethanolic and aqueous extracts against the damaging effects of oxidative stress using different experimental models. The chemical characterization wa...

The main objective of this research was to evaluate the impact of methanolic, ethanolic and aqueous extracts of Origanum majorana L., Origanum vulgare L., Teucrium chamaedrys L., Teucrium montanum L., Thymus serpyllum L. and Thymus vulgaris L. (Lamiaceae) on the effects of free radicals using different model systems. The extracts were characterized...

This study deals with bleak (Alburnus alburnus) sensitivity in detecting of the wastewater related pressure in large lowland rivers. The major objective was to investigate if the response measured in bleak should be linked to a certain stretch of the river and characterised as ”stretch specific”, or it should be linked to the sampling site and char...

Montenegrin surface water and groundwater are important for the Balkan Peninsula since they are connected by the transboundary Dinaric Karst Aquifer System with the waters of additional five countries. The pollution from the surface water can rapidly infiltrate in aquifer and endanger this sensible ecosystem and the health of humans through drinkin...

Tert-butylquinone (TBQ) and its alkylamino and aralkylamino derivatives are of high interest as a potential antitumor agent. Therefore, it was necessary to investigate if the compounds exert undesirable activities such as interaction with DNA molecule which could result in negative side effects in the case of their use in the diseases treatment. Th...

In this study, mutagenic and genotoxic potential of anti-tumor compounds avarol, avarone, and its derivatives 3′-methoxyavarone, 4′-(methylamino)avarone and 3′-(methylamino)avarone was evaluated and compared to cytostatics commonly used in chemotherapy (5-fluorouracil, etoposid, and cisplatin). Mutagenic potential of selected hydroquinone and quino...

The Velika Morava River is the greatest national Serbian river and the significant tributary of the Danube River. The major problems in the Velika Morava River Basin (VMRB) represent untreated industrial and municipal wastewaters. In this study, the level of genotoxic potential at the sites along the VMRB was evaluated by parallel in vitro and in s...

The paper presents data on the composition of epilithic diatoms in the Raška River. Samples were collected by scraping stone surfaces with a brush from 5 localities along the Raška River in April, June, August and November 2011 and March and May 2012. Diatom frustules were cleaned using cold acid method, and mounted on permanent slides. An investig...
