Anti-biofilm activities of essential oils rich in carvacrol and thymol against Enteritidis.

The aim of the present study was to determine the bioactive compounds in four essential oils (EO's) from , , and and to assess their antimicrobial and anti-biofilm activity against Enteritidis. Strains were previously characterized depending on the expression of the extracellular matrix components cellulose and curli fimbriae as rdar (red, dry and rough) and bdar morphotype (brown, dry and rough). This study revealed that the EO's and EOC's (carvacrol and thymol) investigated showed inhibition of biofilm formation at sub-minimum inhibitory concentration.

A Short Measure of the Revised Reinforcement Sensitivity Theory - RSQ17.

The need for a research and practical tool, such as a short, reliable, and valid personality assessment test, suggests researchers to create shortened versions of original instruments. Reinforcement sensitivity questionnaire (RSQ) was created in line with some basic premises of revised Reinforcement sensitivity theory, which proposes three motivational and emotional systems: Behavioral inhibition system (BIS), responsible for scanning environment for potential threats, Behavioral activation system (BAS), responsible for aproaching behavior, and the Fight/Flight/Freeze system (FFFS), responsible for behavior in the present threat. RSQ comprises five scales: BIS, BAS, Fight, Flight, and Freeze.

Fusarium toxins in corn food products: a survey of the Serbian retail market.

This paper presents data on the occurrence of Fusarium toxins - zearalenone (ZEA), deoxynivalenol (DON) and fumonisins (FUMs) B1 and B2 - in corn flours and corn flakes marketed in Serbia. A total of 71 samples were collected over 2013-2016 and analysed using HPLC with UV or fluorescence detection. In the case of corn flours, none of the samples taken in 2013 exhibited the presence of ZEA or DON, whereas 90% were positive for FUMs.

Patulin in fruit juices: occurrence, bioaccessibility, and risk assessment for Serbian population.

This paper reports the first study of patulin occurrence in fruit juices and risk assessment related to patulin intake by children, adolescents and adults in Serbia. During 3 consecutive years (2013-2015), 142 fruit (apple or multi-fruit) juices were collected from the market and analysed using HPLC-UV. Patulin was found in 51.

Aflatoxins and ochratoxin A in flour: a survey of the Serbian retail market.

This report presents data on the occurrence of aflatoxins (AF) and ochratoxin A in different types of flour marketed in Serbia. A total of 114 samples of wheat, buckwheat, rye, oat, barley, rice, millet and corn flour were collected in the period 2012-2016 and analysed using high performance liquid chromatography with fluorescence detection. Among flours other than corn, AFB1 was quantified only in rice, while ochratoxin A (OTA) was found in 29% of the samples.

Risk assessment of patulin intake through apple-based food by infants and preschool children in Serbia.

This study reports for the first time in Serbia the occurrence of patulin in apple-based food and the risk assessment associated with patulin intake by infants and preschool children. In total, 214 samples of infant fruit juices (48), infant purée (66), and juices for children (small package with straw, 100) were collected over 3 years (2013-15) and analysed using HPLC with ultraviolet detection. Patulin was found in 43.

Hydroponic screening of black locust families for heavy metal tolerance and accumulation.

Present work examines phytoextraction potential of four black locust families (half-sibs 54, 56, 115, and 135) grown hydroponically. Plants were treated with 6 ppm of cadmium (Cd), 100 ppm of nickel (Ni), and 40 ppm of lead (Pb) added in Hoagland nutrient solution, accompanying with simultaneously applied all three metals. Responses to metals exposure among families were different, ranging from severe to slight reduction of root and shoot biomass production of treated plants.
