Antimicrobial susceptibility of lactic acid bacteria isolated from Sombor cheese
BulajiSneana,Mija?evi? Zora
Acta Veterinaria , 2011, DOI: 10.2298/avb1103247b
Abstract: Extensive literature data pointed out that some lactic acid bacteria (LABs), the predominant microbiota in fermented dairy products, may serve as reservoirs of antibiotic resistance genes potentially transferable to human pathogens. Hence, there is a growing interest in the possible role of Las vectors of antibiotic resistance determinants. This paper reports the susceptibility patterns of a number of Lspecies (belonging to the genera Lactococcus, Lactobacillus, and Enterococcus) isolated from different batches of autochthonous Sombor cheese, traditionally made without the addition of starter cultures, and currently proposed as a candidate for PDO/PGI designation. The experimental work was performed to select strains that do not contain antibiotic resistance genes among those with desirable technological characteristics such as rapid acidification, proteolysis, ability to metabolise citrate and form aromogenic compounds. In addition, the results of these screening procedures could also indicate the types and degrees of antimicrobial resistance already present among the Lcommunity of Sombor cheese, which according to their geographically restricted areas of production, specific manufacturing process and characteristic aroma and appearance, represent a distinct ecological niche.
Sensory evaluation and microbiological characterization of autochthonous Sombor cheese

Acta Veterinaria , 2008, DOI: 10.2298/avb0806531m
Abstract: In this paper the results of organoleptic evaluation, chemical and microbiological analysis of Sombor cheese were presented. Sombor cheese is a type of autochthonous cheese whose traditional processing method is still in use in areas of northern part of Serbia. The sensory profile, chemical and microbiological analysis were performed on 19 samples of traditionally made cheese collected from two households. The sensory evaluation of cheese samples showed its variation in taste and consistency, as well as an unstable cheese flavour. Generally, the traditionally made Sombor cheese in wood modules received a higher score than the cheese produced in the cylindric form. According to the fat content in dry matter Sombor cheese can be classified as a fat cheese and depending of water content in non fat cheese matter, Sombor cheese belongs to the group of soft cheeses. Fat in dry matter and content of total nitrogen showed great variations which indicate the unevenness in technology and unconsistent quality of the raw substrate. Results of microbiological examination showed that lactic acid bacteria were the most abundant flora during manufacturing and early ripening of this cheese. Among them, Lactococci, Lactobacilli and Enterococci represented the main microbial groups of lactic microflora.
Antibiotic resistance of lactic acid bacteria
BulajiSneana,Mija?evi? Zora,Savi?-Radovanovi? Radoslava
Veterinarski Glasnik , 2008, DOI: 10.2298/vetgl0806329b
Abstract: Knowledge on the antibiotic resistance of lactic acid bacteria is still limited, possibly because of the large numbers of genera and species encountered in this group, as well as variances in their resistance spectra. The EFSA considers antibiotic resistances, especially transferable resistances, an important decision criterion for determining a strain's QPS status. There are no approved standards for the phenotypic or genotypic evaluation of antibiotic resistances in food isolates. Also, the choice of media is problematic, as well as the specification of MIC breakpoint values as a result of the large species variation and the possible resulting variation in MIC values between species and genera. The current investigations in this field showed that we might end up with a range of different species- or genus-specific breakpoint values that may further increase the current complexity. Another problem associated with safety determinations of starter strains is that once a resistance phenotype and an associated resistance determinant have been identified, it becomes difficult to show that this determinant is not transferable, especially if the resistance gene is not located on a plasmid and no standard protocols for showing genetic transfer are available. Encountering those problems, the QPS system should allow leeway for the interpretations of results, especially when these relate to the methodology for resistance phenotype determinations, determinations of MIC breakpoints for certain genera, species, or strains, the nondeterminability of a genetic basis of a resistance phenotype and the transferability of resistance genes.
Concept of protection of food of animal origin
Mija?evi? Zora M.,BulajiSneana B.
Veterinarski Glasnik , 2005, DOI: 10.2298/vetgl0502167m
Abstract: The currently valid regulations (Official Gazette 26/2002) define the requirements for the quality of milk and milk products. The same legislature defines also the concept of composite products, that is, products in which part of the fat or proteins have been substituted with fat or proteins of different origin. A composite product must include the term composite in its name, and the part of the declaration which lists the contents of total proteins and fat must specify the part of plant proteins and fat in total proteins and fat of milk products. With the growth of the population and the concern for health, new requirements have been set, and consumers expect a food article to meet not only the nutritive requirements, but also to have certain functional characteristics, or that it is not burdened with components which have a negative effect on health (the presence of cholesterol, sodium chloride, a high percentage of saturated fatty acids). The complete substitution of one milk component results in a completely new product. A change in the traditional composition of a certain food article must be clearly declared, so as not to confuse consumers and to provide them with the possibility of choice. In our market, there have lately appeared products that are marked as imitations, alternatives, diet cheese, vegetable cheese. Modified products which do not meet the traditional identity standards must be marked as imitations, in case they are nutritionally inferior with respect to the traditionally standardized food articles, or as substitutes or alternatives, in the event that they are a nutritive equivalent to the traditional food articles. The lack of legal regulations for this category of product leads to the irregular declaration of such products, and consequently provides false information about the characteristics of such articles to the consumer. It is necessary to regulate this area with the respective laws in order to protect the consumer.

Mljekarstvo , 2005,
Abstract: In the Stara planina region, around county Pirot, in the last 100 years the production of kachkaval cheese, known in the wide region as Pirotski kachkaval, has been developed. Stara Planina is well known by its pastures for sheep and cattle, high height above the sea level and specific climate. Pirotski kachkaval was produced on Stara planina in the period of sheep pasture, May - September. It was manufactured traditionally by soaking of mature cheese (baskija) and hand making a wheel of cheese. Ripening and salting of cheese in the climate conditions of Stara Planina, gave recognizable taste of Pirotski kachkaval. The necessity of protection of traditionally manufactured Pirotski kachkaval cheese, brought up the investigations which proved that all characteristics of cheese produced in traditional way, are kept, pointing out that this unique procedure satisfies demands for PDO (Protected Denomination of Origin) mark.

Technology and Investment (TI) , 2014, DOI: 10.4236/ti.2014.52008

The paper gives a brief elaboration of the basic macroeconomic aspects of investments with emphasis on the specificities of small open economies in the process, theoretically elaborates the need for openness of small economies (especially the economies that need the acceleration of their development), then highlights the risks and opportunities arising from the investment activity both on the micro and macro level. Further distinguishes between investments in financial instruments and in real investment projects, emphasize the need for creation of an optimal diversified portfolio. Finally, the paper underlines the need for various forms of foreign direct investment for all economies, particularly the opportunities and threats arising in small open economies, to complete the wholeness with empirical data of the previously elaborated matters on the example of the Republic of Macedonia as a small open economy.

MARP Protein Family: A Possible Role in Molecular Mechanisms of Tumorigenesis

Journal of Medical Biochemistry , 2010, DOI: 10.2478/v10011-010-0024-9
Abstract: The MARP (muscle ankyrin repeat protein) family comprises three structurally similar proteins: CARP/Ankrd1, Ankrd2/Arpp and DARP/Ankrd23. They share four conserved copies of 33-residue ankyrin repeats and contain a nuclear localization signal, allowing the sorting of MARPs to the nucleus. They are found both in the nucleus and in the cytoplasm of skeletal and cardiac muscle cells, suggesting that MARPs shuttle within the cell enabling them to play a role in signal transduction in striated muscle. Expression of MARPs is altered under different pathological conditions. In skeletal muscle, CARP/Ankrd1 and Ankrd2/Arpp are up-regulated in muscle in patients suffering from Duchene muscular dystrophy, congenital myopathy and spinal muscular atrophy. Mutations in Ankrd1 gene (coding CARP/Ankrd1) were identified in dilated and hypertrophic cardiomyopathies. Altered expression of MARPs is also observed in rhabdomyosarcoma, renal oncocytoma and ovarian cancer. In order to functionally characterize MARP family members CARP/Ankrd1 and Ankrd2/Arpp, we have found that both proteins interact with the tumor suppressor p53 both in vivo and in vitro and that p53 up-regulates their expression. Our results implicate the potential role of MARPs in molecular mechanisms relevant to tumor response and progression.

Abstract: The Third Report of the expert panel on detection, evaluation and treatment of high blood cholesterol in adults (Adult Treatment Panel III, ATP III) constitutes the National Cholesterol Education Program's (NCEP's) updated clinical guidelines for cholesterol testing and clinical management of patients with high blood cholesterol. While ATP III maintains attention to intensive treatment of patients with coronary heart disease (CHD), its major new feature is a focus on primary prevention in persons with multiple risk factors. ATP III continues to identify elevated LDL cholesterol as the primary target of cholesterol lowering therapy. A basic principle of prevention is that the intensity of risk reduction therapy should be adjusted to a person's absolute risk. Risk assessment requires measurement of LDL cholesterol as part of lipoprotein analysis and identification of accompanying risk determinants (presence or absence of CHD, other clinical forms of atherosclerotic disease, diabetes, cigarette smoking, hypertension, low HDL cholesterol, family history of premature CHD, age). The category of highest risk consists of CHD and CHD risk equivalents - persons with absolute 10-year risk for major coronary events (death and myocardial infarction) >20%. The second category consists of persons with multiple (2+) risk factors in whom 10-year risk for CHD is ≥20%. Absolute risk is estimated from Framingham risk scores. The third category consists of persons having 0-1 risk factor. The LDL cholesterol goal for each category is defined and it can be achieved with dietary changes and/or drug therapy. European guidelines on cardiovascular disease (CVD) prevention in clinical practice recommend using the SCORE (Systematic COronary Risk Evaluation) Risk Charts in order to assess the risk for development of CVD, which is defined in terms of the absolute 10 year probability of developing a fatal cardiovascular event. The aim of this paper is to introduce parts of the NCEP's ATP III and European guidelines important for their implementation in laboratory practice.

Abstract: In present times, there is a clear and growing need for applying theoretical biogeographic achievements in improving the state of biodiversity and conservation. Conceptual principles of conservation biogeography take the research into the relationship between fundamental biogeographic principles and the need for their appliance in nature conservation as the basic theory model, based upon biogeographic studies of isolated ranges. This paper is meant to point out the differences between spatial and functional isolation and the effects these have on the stability of populations and species. In light of this need to apply theories in biodiversity and nature conservation, it is important to research not only the processes that depend solely upon natural factors, but also those that are caused by a number of human-induced changes, e.g. habitat fragmentation, climate change or biotic homogenization.
Forests as the factor of the economy development of the Ra ka region

Glasnik Srpskog Geografskog Dru?tva , 2003, DOI: 10.2298/gsgd0302061v
Abstract: Forests represent the significant natural resource of the Ra ka region. The preservation of forests ecosystems, and space potential offer, a favourable basis for their many-functional usage. For the time being, the productive, i.e., economic function, is dominant. The forests on the territory of the Prijepolje Forest Organization present the main raw material basis. In the whole cut wood volume of Serbia (state forests), the above mentioned organization participates with 37,1%. Opposite to that fact, the economic effects that the region economy has from the forest utilization, are far less than the potentials. Forest resources are neither enough nor adequately used. That greatly complicates the development of wood industry, as well as the other activities whose prosperity is connected with forests. Making and realization of plans for protection, fending forests and utilization, constructing infrastructure, tending and preservation of wild life, rational exploitation of forest resources, are the trends of the future usage of the Ra ka region forest natural wealth.
