The effects of human recombinant epidermal growth factor (EGF) on rat articular chondrocytes from humeral and femoral head cartilage of 21-day-old Wistar rats were analyzed. The cells were cultured under standard conditions as monolayers. Cell proliferation was studied by [3H]thymidine incorporation and determination of DNA content, proteoglycan synthesis(More)
The aim of this study was to investigate whether Escherichia coli O157 is present in/on raw beef in Serbia. Correlated faecal and carcasses samples from 115 slaughtered cattle plus 26 uncorrelated carcass samples were examined. E. coli O157 detection and identification was performed using selective enrichment and immunomagnetic separation followed by(More)
AIMS To obtain the first information on the occurrence of Escherichia coli O157 on hides of slaughtered cattle in Serbia. METHODS AND RESULTS A total of 355 swabs were taken on the slaughterline from five areas of hide of each of the 71 cattle in a single commercial abattoir in Serbia. Using an ISO method incorporating enrichment and immunomagnetic(More)
A solution of natural, food-grade resin (Shellac) in ethanol was evaluated to treat samples of visually clean and dry cattle hides with the aim to reduce bacterial removability from the hides by swabbing. Hide treatment by 23% Shellac-in-ethanol solution reduced sponge-swabbing recoveries of general microflora (TVC) by a factor of 6.6 logs (>1000-fold(More)
The effects of interleukin-1 (IL-1), tumor necrosis factor-alpha (TNF-alpha), and lipopolysaccharide (LPS) on the productions of nitric oxide (NO) and cGMP by cultured articular chondrocyte (AC) monolayers from 1-, 8- and 18-month old male Wistar rats were studied. It was found that basal NO and cGMP productions decrease with the age of animals. The(More)
The purpose of this study was to evaluate the storage conditions as a way to increase the safety of fermented sausage, with the specific objectives to investigate the effect of storage time, pH value, water activity and microbiological status (Lactobacillus spp. and Enterobacteriaceae) on the levels of Yersinia enterocolitica in fermented sausages. For this(More)
The aim of this paper is to investigate the effects of competing trade regimes on Serbian trade with its most significant (traditional) partners, like European Union and CEFTA 2006 signatories, and other untraditional trade partners with favourable trade regime, like the USA. To this end, gravity model with bilateral and time effects is estimated by(More)
