Foramina parietalia permagna: Case report
Nikoli? Slobodan,?ivkovi? Vladimir,Strajina Veljko
Srpski Arhiv za Celokupno Lekarstvo , 2012, DOI: 10.2298/sarh1210658n
Abstract: Introduction. In forensic autopsy, pathologists are not particularly interested in the anatomical morphological variations of the skull bones, especially if those variations are not very frequent. Foramina parietalia permagna are developmental benign anomalies resulting from large ossification defects of the parietal bone. Case Outline. Herein was presented a case of 80-year-old female, whose autopsy revealed congenital defect of parietal bones - enlarged parietal foramina. These defects were capped by a fibrous membrane and covered by normal scalp. This condition was completely asymptomatic. Despite the fact that the deceased was very old, the giant parietal foramina were recognized. Conclusion. The forensic pathologist must know how to recognize morphological variations of the skull bones, such as foramina parietalia permagna despite their rare occurrence. This benign anomaly could be associated with anomalies of cerebral venous development and cortical infolding, or asymptomatic as in the presented case. This anomaly of parietal bones could be a useful tool in the identification of forensic cases. [Projekat Ministarstva nauke Republike Srbije, br. 45005]

Simi? Du?ica,Milojevi? Irina,Budi? Ivana,Strajina Veljko
Srpski Arhiv za Celokupno Lekarstvo , 2009, DOI: 10.2298/sarh0910537s
Abstract: Introduction Immunosuppressive effects of general anesthesia and surgery could have unexpected consequences in a child with recent infection. The incidence of myocarditis in childhood is unknown. Case outline During general anesthesia for inguinal hernia repair, a seven-year-old boy suddenly developed heart failure. Clinical presentation included hypotension, pulmonary edema, drop in hemoglobin oxygen saturation, ST segment elevation and premature ventricular contractions. Homodynamic stability and adequate oxygenation were achieved with dopamine and furosemide. Preoperative history, physical examination and complete blood count were unremarkable. Moderate cardiomegaly and pulmonary edema were present on chest radiography. Diminished left ventricular contractility found on echocardiography increased troponin I and CK-MB levels suggested myocardial injury. Increased C-reactive protein with lymphocytosis suggested inflammation as its cause. Parents failed to report rubella 10 days before the operation. A clinical diagnosis of myocarditis as a complication of rubella was based on increased titer of IgM to rubella. With intravenous immunoglobulin, corticosteroids and symptomatic treatment for heart failure, his condition improved and ejection fraction reached 68 % one month after operation. Conclusion In future, we need protocols with instructions for pediatric patients undergoing elective surgery and anesthesia after viral infections.

Molecules , 2000, DOI: 10.3390/50400674
Abstract: Reaction of enone (11) with the bifunctional Grignard reagent (7) in the presence of copper(I) bromide – dimethyl sulfide, followed by intramolecular alkylation of the resultant chloroketone (15) gave the tricyclic ketone (12). The tricyclic ketone (12) was transformed into the angular triquinane dienedione (9) by means of an 8-step sequence.
Pseudomnas syringae – a Pathogen of Fruit Trees in Serbia
Veljko Gavrilovi?
Pesticidi i Fitomedicina , 2009,
Abstract: Data about symptomatology, pathogenicity and bacteriological characteristics of Pseudomonas syringae, and PCR methods for fast and reliable detection of the pathogen are given in this paper. P. syringae has been experimentaly proved as a pathogen of pear, apple, apricot, plum cherry, and raspberry, and pathogen strains have also been isolated from necrotic peach buds. Two pathogen varieties, syringae and morsprunorum, were found in our research in Serbia, the former being dominant on fruit trees.The most reliable method for detection of this bacteria is PCR, using BOX and REP primers. This method has also revealed significant differences among the strains originating from fruit trees in Serbia. Thus, it was proved that the population of P. syringae in Serbia is heterogeneous, which is very important for future epidemiologocal studies. Control of this pathogen includes mechanical, cultural and chemical measures, but integrated approach is very important for sustainable control.

Antibiotic resistance of hospital strains of Enterococcus faecalis and Enterococcus faecium
Mirovi? Veljko
Vojnosanitetski Pregled , 2002, DOI: 10.2298/vsp0205499m
Abstract: The aim of this study was to determine the resistance of Enterococcus faecalis (E. faecalis) and Enterococcus faecium (E. faecium) to penicillin, ampicillin, vancomycin, teicoplanin, gentamicin (high level), streptomycin (high level), oxytetracycline, chloramphenicol, rifampin, erythromycin, ciprofloxacin, norfloxacin, and nitrofurantoin from clinical specimens during 1999. The resistance of enterococci to antibiotics was determined by disk diffusion and dilution methods according to the American National Committee for Clinical Laboratory Standards guidelines. The production of β-lactamase was determined by nitrocefin disks. In E. faecalis and E. faecium isolates (n=111 and n=48) the frequency of the resistance to both penicillins was 0.9% and 89.6%, respectively. All enterococci isolates were β-lactamase negative. Only one strain of E. faecium was vancomycin resistant (Van A fenotype). Among E. faecalis isolates (n=109) high level gentamicin resistance (HLGR), high level streptomycin resistance (HLSR), and resistance to both agents was 52.3%, 50.4%, and 43.7%, respectively. Among E. faecium isolates (n=48) HLGR, HLSR, and to both agents were 68.7%, 75%, and 62.5% respectively. The majority of E. faecium isolates were resistant to both penicillin and ampicillin. E. faecalis remained susceptible to penicillins. Moreover, there was a very high incidence of enterococci resistant to high level aminoglycosides.
Integral rural development: Toward a more harmonious regional development
Radovanovi? Veljko
Zbornik Matice Srpske za Drustvene Nauke , 2010, DOI: 10.2298/zmsdn1032041r
Abstract: The paper discusses the integral rural development and its importance for the policy of a more balanced regional development. Highly emphasized regional disproportions in almost all domains, as well as the long-standing lagging behind in the development of village and agriculture, resulted in faltering and stagnation of total development of the country. Overcoming, this problem calls for application of a more complex model of developmental policy for the village and rural society, which demand a multidisciplinary approach. Active policy and promotion of integral rural development is not only in the interest of rural communities, but of the society as a whole. This implies that investment in a wide range of economic branches in rural areas is of vital importance for increasing the attractiveness of rural areas, encouragement of sustainable development and creation of new possibilities for employment, especially of young educated people who are ready and capable to accept the new philosophy of development of these areas. Although rural areas in Serbia observed as a whole are highly heterogeneous with respect to economic development, according to the basic parameters of development degree, they lag behind urban and industrial centers considerably, and much more attention should be devoted to this phenomenon in the future.
Phase-vanishing halolactonization of neat substrates
Nicole Windmon,Veljko Dragojlovic
Beilstein Journal of Organic Chemistry , 2008, DOI: 10.3762/bjoc.4.29
Abstract: Phase-vanishing reactions are triphasic reactions which involve a reagent, a liquid perfluoroalkane as a phase screen and a substrate. The perfluoroalkane does not dissolve any of the reactants and is used to separate them. Halolactonization of neat substrates under phase-vanishing conditions avoids use of both solvents and basic reaction conditions. Both γ,δ-alkenoic acids as well as the corresponding methyl esters are suitable substrates for phase-vanishing halolactonizations. The reaction works well both on solid and liquid substrates and the products are obtained in good to excellent yields, particularly in the case of rigid bicyclic systems. Bromine (Br2) and iodine monochloride (ICl) are suitable electrophiles for bromolactonization and iodolactonization, respectively. Although in some cases iodine gave satisfactory yields of the corresponding iodolactone, it is generally inferior to iodine monochloride.
Solvent-free phase-vanishing reactions with PTFE (Teflon ) as a phase screen
Kevin Pels,Veljko Dragojlovic
Beilstein Journal of Organic Chemistry , 2009, DOI: 10.3762/bjoc.5.75
Abstract: In a solvent-free phase-vanishing reaction with PTFE (polytetrafluoroethylene, Teflon ) tape as the phase screen, a thermometer adapter is utilized to insert a PTFE-sealed tube into the vapor phase above the substrate. Besides avoiding use of solvents, the experimental design is not dependent upon the densities of the reactants and the procedure generates little or no waste while providing the reaction products in high yield and in high purity.
Potential of waste heat in Croatian industrial sector
Bi??an Davor,Filipan Veljko
Thermal Science , 2012, DOI: 10.2298/tsci120124123b
Abstract: Waste heat recovery in Croatian industry is of the highest significance regarding the national efforts towards energy efficiency improvements and climate protection. By recuperation of heat which would otherwise be wasted, the quantity of fossil fuels used for production of useful energy could be lowered thereby reducing the fuel costs and increasing the competitiveness of examined Croatian industries. Another effect of increased energy efficiency of industrial processes and plants is reduction of greenhouse gases i.e. the second important national goal required by the European Union (EU) and United Nations Framework Convention on Climate Change (UNFCCC). Paper investigates and analyses the waste heat potential in Croatian industrial sector. Firstly, relevant industrial sectors with significant amount of waste heat are determined. Furthermore, significant companies in these sectors are selected with respect to main process characteristics, operation mode and estimated waste heat potential. Data collection of waste heat parameters (temperature, mass flow and composition) is conducted. Current technologies used for waste heat utilization from different waste heat sources are pointed out. Considered facilities are compared with regard to amount of flue gas heat. Mechanisms for more efficient and more economic utilization of waste heat are proposed. [Acknoledgment.
