Tembotrione is herbicide which belongs to the triketone group of herbicides. It’s registered as a selective, post-emergence herbicide developed for the control of a broad spectrum broadleaf and grassy weeds in corn. There is little information about tembotrione because of his short presence in the market. Due to its ever wider application, it is important to know the details of its chemical characteristics and redox processes, including biogeochemical transformation and migration after application to agricultural land, which could contribute to its efficient and safer application. In this paper we examined voltammetric behavior of tembotrione using Silver/Amalgam (Ag/Hg) electrode. For the investigation of electrochemical behavior we used the cyclic voltammetry technique, with conventional three-electrode cell and electrochemical workstation. During the experiment pH values of solution varieties while constant concentration of tembotrione was maintained. Cyclic voltammograms were recorded at pH values 6, 8, 10 and 12, at which tembotrione was electrochemically active. At this pH values two signals were observed. Optimum pH value, at which the current intensity was greatest, was 12. Obtained results provide relevant information on the electrochemical behavior of tembotrione, which can serve as a basis for the development of electrochemical techniques for the removal and degradation of this pesticide in the environment.

Abstract: This paper presents the results of a research of velocity of air circulation in the conventional kiln drying of sawn timber and its influence on the uniformity of final moisture content. The data showed that the air velocity (between 0.8 - 1.2 m s -1) is significantly lower than the one that is optimal for timber drying of coniferous species (3 - 4 m s-1). This results in a reduction in the capacity of installations for drying, increased energy (thermal and electrical) consumption and thereby increase in the cost of drying. The correlation between the speed of air circulation and the final MC of timber due to prolonged drying was not established. Recommendations that should eliminate the identified deficiencies are also given.

Abstract: Nowadays antimicrobial prophylaxis represents a unique approach for reducing the incidence of wound infection associated with surgical procedures. Recommendations for antimicrobial prophylaxis may be specific according to type of the procedure, causative agents, schedules and drug doses. It is important to note optimal timing of drug administration, and the optimal duration of prophylaxis in order to adjust maximal drug concentration in tissues that probably might be contaminated during the surgery. Currently it is recommended to receive antimicrobial prophylaxis at anesthesia induction as a short course that should have duration from 12-24 hours, while postoperative prophylaxis proved to be infective. The best route of administration is parenteral, while other routes are not so common. It is important to weigh costs of treatment of patients with developed postoperative wound infection who did not receive any prophylaxis, against cost and morbidity of patients who had received antimicrobial prophylaxis.

Abstract: The goal of this research was to evaluate the efficiency of heat treated nectarine fruit (Prunus persica var. nectarina ‘Diamond Ray’) on maintaining the quality parameters after 4 week storage in NA (normal atmosphere) at 0°C and 5 days at 20°C (shelf life). Fruits were harvested closer to “ready-to-eat” maturity from a commercial orchard near Zadar (Croatia). The investigated postharvest treatments were hot air (hot air treatment till fruit reaches 45°C near stone – HAT 45/24) and immersion in hot water at a temperature of 48 °C for 6 minutes (HWD 48) and 52°C for 2 minutes (HWD 52). Fruit quality parameters (firmness, soluble solids, total acidity, pH) were also investigated. HAT 45/24 reduced weight loss and maintained firmness more than control or hot water treatments. Overall, heat treatments had a pronounced effect on decreasing decay, reducing chilling injury and maintaining quality of climacteric nectarine fruit. These treatments may extend the storage life by preventing both pathological and physiological disorders.

Abstract: Background. The Mounier-Kuhn syndrome (MKS) or tracheobronchomegaly (TBM) is a rare condition of unknown frequency, up to now about 100 cases have been reported. It presents by marked dilatation of the trachea and major bronchi, recurrent respiratory infections and consecutive bronchiectasis and scars in lung parenchyme. Sometimes enlargement of transversal colon may be present. Diagnosis is usually made radiologically. Cases report. We reviewed two patients 77 and 72 years old with typical clinical presentation and enlarged upper airways, in whom diagnosis of MKS was established by chest multislice computed tomography (MSCT). Transversal diameter of trachea was 30 mm in the first patient and 33 mm in the other one. Complications of syndrome (tracheal diverticulosis in the first patient, and pulmonary fibrosis, bulous emphysema and bronchiectasis in both patients) also were seen. Lung function tests showed mixed ventilation disorder, and disturbance of respiratory gases values in arterial blood samples. Conclusion. The Mounier-Kuhn syndrome is rare disorder, although diagnosis is often missed. Clinical presentation is similar to chronic obstructive pulmonary disease or bronchiectasis. Computed tomography is gold standard for diagnosis. Therapy is presumely supportive.

Abstract: Introduction. Nitrofurantoin, a furan derivative, introduced in the fifties has widely been used as an effective agent for the treatment and prevention of urinary tract infections (UTI). Spectrum of adverse reactions to nitrofurantoin is wide, ranging from eosinophilic interstitial lung disease, acute hepatitis and granulomatous reaction, to the chronic active hepatitis, a very rare adverse effect, that can lead to cirrhosis and death. Case report. We presented a 55-year-old female patient with eosinophilic interstitial lung disease, severe chronic active hepatitis and several other immune- mediated multisystemic manifestations of prolonged exposure to nitrofurantoin because of the recurrent UTI caused by Escherichia coli. We estimated typical radiographic and laboratory disturbances, also restrictive ventilatory changes, severe reduction of carbon monoxide diffusion capacity and abnormal liver function tests. Lymphocytic-eosinophylic alveolitis was consistent with druginduced reaction. Hepatitis was confirmed by liver biopsy. After withdrawal of nitrofurantoin and application of high dose of glicocorticosteroids, prompt clinical and laboratory recovery was achieved. Conclusion. Adverse drug reactions should be considered in patients with concomitant lung and liver disease. The mainstay of treatment is drug withdrawal and the use of immunosuppressive drugs in severe cases. Consideration should be given to monitor lung and liver function tests during long term nitrofurantoin therapy.

Vojnosanitetski Pregled , 2008, DOI: 10.2298/vsp0809681s
Abstract: Background/Aim. Fibrin glue is used as a matrix for local application of antibiotics. The aim of this study was to determine whether application of fibrin glue in combination with antibiotics can strengthen collagen production, prevent dehiscence of colon anastomoses due to infection, and reduce frequency of mortality and morbidity comparing to the control group and the group with fibrin glue application. Methods. The adult male Wistar rats divided into three groups were used in the experiment. The group 1 was the control one (after partial colon resection, colonic anastomoses performed were not treated), while to the group 2 and the group 3 were applied fibrin glue and fibrin glue with antibiotics (clindamycin and ceftriaxon) on the site of anastomoses, respectively. Quality of colonic anastomoses were estimated by means of determination of collagen (L-hydroxyproline) amount in the collon wall with anastomoses and histological analysis of this colon segment using light and electronic microscope on the days 5, 7 and 13 postoperatively. Results. The highest morbidity rate was registered in the group 1 (30%), then in the group 2 (13.3%) and the lowest one in the group 3 (3.33%; p < 0,05 vs group 1). Mortality rate was significantly higher in the group 1 than in the group 3 (20% and 0%, respectively; p < 0,05). In the postoperative course, the highest concentrations of collagen in the colon wall on the site of anastomoses, which was confirmed by both light and electronic microscopy, were found in the group 3. Conclusion. The application of fibrin glue with antibiotics on colon anastomoses reduces the number of dehiscence, provides good mechanical protection and shorten the time of anastomoses healing.

Abstract: Background/Aim. Inflammation is an important factor in the pathogenesis of atherosclerosis, and several markers of inflammation have been associated with an increased risk of cardiovascular events. Physical activity may lower the risk for coronary heart disease (CHD) by mitigating inflammation. The aim of this study was to investigate the effects of aerobic physical exercise on systemic inflammatory response in patients with stable coronary disease participating in a cardiovascular rehabilitation exercise program. Methods. Male (n = 29) and female (n = 23) patients with stable coronary heart disease were enrolled in this study. All the patients were divided into two groups: the group with regular aerobic physical training during cardiovascular rehabilitation program phase II for 3 weeks in our rehabilitation center and 3 weeks after that in their home setting, and sedentary lifestyle group. There were no significant differences in gender distribution among the analyzed groups. Student's t-test showed no significant differences in average age, waist circumference (OS) and waist/hip ratio (WHR). Results. The degree of obesity was measured by BMI and there was a significant improvement in BMI in the patients who undertook 6-week physical training compared to the controls (p < 0.05). Physical training during 6-week appeared not to have any effects on leukocite count and ICAM-1 levels compared to controls. Exercise induced reduction in plasma CRP levels by 23.72% (p < 0.001) and reduction in plasma VCAM-1 levels by 10.23%, (p < 0.05). Conclusion. Moderate aerobic exercise resulted in a significant reduction of inflammatory state by decreasing CRP and VCAM-1 levels with significant obesity reduction but without visceral obesity reduction. The obtained results indicate that regular physical activity is clinically desirable in primary and secondary prevention of coronary heart diseases.

Abstract: In spite of the progress made in diagnostic procedures and development of the operating rooms technology, considerable neurological deficit after operation of tumors localized in the brain motor zone commits one to direct intraoperative identification of the motor zone. By introducing direct electrocortical stimulation into the routine intraoperative application the primary goal has been achieved - reaching the maximum degree of radicalness of surgical resection while preserving motor centres in the cerebral cortex. Method: We are hereby demonstrating a series of 60 patients operated for primary brain tumors localized in the area in the front and around the central sulcus. All operations have been performed under the general anesthetics. During the operations the method of direct electrostimulation (ES) was used for the purpose of identifying motor centres. Results: Intraoperatively a level of subtotal resection was achieved in 22 cases, while radical resection was possible in 38 cases. Significantly higher level of radicalness of surgical resection of the low grade glioma tumor was confirmed statistically in relation to the group of patients with glioblastoma multiforme by applying the ES cortex (p<0,05). Patients with slow developing brain glioma have statistically considerably higher KI value in relation to the KI values in the group of patients with glioblastoma multiforme (p<0,01). Difference in the measured values of distance from the coronal suture based on the results of MRI measuring and finding obtained by ES, has shown a statistically considerably higher difference with glioblastoma multiforme 8,26+4,288mm when comapred to slowly developing astrocitoma 5,88+3,080 (p<0,05). Conclusion: Electrostimulation of the brain cortex is a safe, simple and precise method for identification of the brain motor zone which enables prevention of additional postoperative deficit and higher level of surgical radicalness.

Abstract: The paper presents the results of the analysis of pipe branch A6 to feed the Hydropower Plant ”Peru ica” with integrated action Pelton turbines. The analysis was conducted experimentally (tensometric) and numerically. The basis of the experimental research is the numerical finite element analysis of pipe branch A6 in pipeline C3. Pipe branch research was conducted in order to set the experiment and to determine extreme stress states. The analysis was used to perform the determination of the stress state of a geometrically complex assembly. This was done in detail as it had never been done before, even in the design phase. The actual states of the body pipe branch were established, along with the possible occurrence of water hammer accompanied by the appearance of hydraulic oscillation. This provides better energetic efficiency of the turbine devices. [Projekat Ministarstva nauke Republike Srbije, br. TR35049 and br. TR 33040]
