Bisphenol A (BPA) is a ubiquitous environmental pollutant which is often associated with various health issues. In this study 103 healthy female volunteers in reproductive age from Serbian north province Vojvodina were enrolled and examined for the BPA exposure in the urine samples after 12 h of fasting. BPA was found in 35.92 % (37/103) of subjects. Statistically significant increment in waist circumference (p = 0.045) and waist-to-height ratio (p = 0.037) was observed among the BPA positive women in comparison with the women who had the same energetic balance and had not been exposed to BPA. Linear correlation was obtained between the BPA concentration in urine samples and body mass index (r = 0.35, p = 0.003) waist circumference (r = 0.21, p = 0.02) and waist-to-height ratio (r = 0.25, p = 0.01) among the obese. High energetic intake and reduced physical activity additionally pronounced BPA positive association with obesity. No statistically significant difference was observed in triglycerides, HDL and LDL cholesterol levels between the BPA exposed and BPA non-exposed female volunteers.
The research is designed to examine the effect of working capital management on company's profitability in the food industry in Southeast Europe, during the five years period (2010-2014). The sample included 9883 active companies. The influence of certain variables of working capital management (current liquidity, the ratio of current to total assets of companies, the ratio of current liabilities to total assets of companies, financial leverage and size of the company) was measured on the probability of higher profitability by applying probit regression analysis. The results of probit regression provide support to a hypothesis that most of the analyzed variables of working capital management have statistically significant impact on the probability of higher profitability. In this paper is also researched how the optimal level of working capital management can contribute to the growth of profitability and value of the company as a whole.
