| 2 | Local Proinflammatory Effects of Repeated Skin Exposure to Warfarin, An Anticoagulant Rodenticide in Rats显示文摘Objective: To evaluate the effects of epicutaneous application of anticoagulant warfarin, by examining the presence of tissue injury and immune/inflammatory activity in exposed skin. Methods: Rats were exposed to warfarin by applying 10 μg of warfarin‐sodium to 10‐12 cm 2 skin (range 0.8‐1 μg per 1 cm 2 ) for 3 consecutive days. Tissue injury was evaluated by lipid peroxidation, histomorphological changes and signs of reparative activity in skin. T cell infiltration and selected aspects of epidermal cell activity were examined as indicators of immune/inflammatory skin response to warfarin application. Results: Repeated warfarin application exerted no effect on skin metabolic viability, but resulted in tissue injury (increased malondialdehyde, MDA, production, evident histo‐morphological changes in epidermis and dermis depicting cell injury and death). Increased numbers of proliferating cell nuclear antigen (PCNA + ) cells indicated reparative processes in injured skin. Infiltration of CD3 + cells (T lymphocytes) along with the increased production of tumor necrosis factor‐α (TNF‐α) by epidermal cells from warfarin‐treated skin and their co‐stimulatory effect in an in vitro T‐cell activation assay demonstrated immunomodulatory effects of epicutaneous warfarin. Conclusion: Presented data have documented tissue damage associated with immune/ inflammatory activity in skin exposed to warfarin. Observed effects are relevant to immunotoxic potential of this anticoagulant in settings of external exposure. | Aleksandra POPOV Ivana MIRKOV Lidija ZOLOTAREVSKI Milena JOVIC Sandra BELIJ Dragan KATARANOVSKI Milena KATARANOVSKI | 2011 | Biomedical and Environmental Sciences2011,24,2: | 13 |
| 3 | Hepatocellular carcinoma: From clinical practice to evidence-based treatment protocols显示文摘Hepatocellular carcinoma(HCC) is one of the major malignant diseases in many healthcare systems. The growing number of new cases diagnosed each year is nearly equal to the number of deaths from this cancer. Worldwide, HCC is a leading cause of cancerrelated deaths, as it is the fifth most common cancer and the third most important cause of cancer related death in men. Among various risk factors the two are prevailing: viral hepatitis, namely chronic hepatitis C virus is a well-established risk factor contributing to the rising incidence of HCC. The epidemic of obesity and the metabolic syndrome, not only in the United States but also in Asia, tend to become the leading cause of the long-term rise in the HCC incidence. Today, the diagnosis of HCC is established within the national surveillance programs in developed countries while the diagnosis of symptomatic, advanced stage disease still remains the characteristic of underdeveloped countries. Although many different staging systems have been developed and evaluated the BarcelonaClinic Liver Cancer staging system has emerged as the most useful to guide HCC treatment. Treatment allocation should be decided by a multidisciplinary board involving hepatologists, pathologists, radiologists, liver surgeons and oncologists guided by personalized-based medicine. This approach is important not only to balance between different oncologic treatments strategies but also due to the complexity of the disease(chronic liver disease and the cancer) and due to the large number of potentially efficient therapies. Careful patient selection and a tailored treatment modality for every patient, either potentially curative(surgical treatment and tumor ablation) or palliative(transarterial therapy, radioembolization and medical treatment, i.e., sorafenib) is mandatory to achieve the best treatment outcome. | Danijel Galun Dragan Basaric Marinko Zuvela Predrag Bulajic Aleksandar Bogdanovic Nemanja Bidzic Miroslav Milicevic | 2015 | World Journal of Hepatology2015,7,20: | 13 |
| 4 | Comethylation of p16 and MGMT genes in colorectal carcinoma:Correlation with clinicopathological features and prognostic value显示文摘AIM: To investigate the significance of p16 and O6- methylguanine-DNA methyltransferase (MGMT) genes promoter hypermethylation and K-ras mutations on colorectal tumorigenesis and progression. METHODS: p16 and MGMT methylation status was examined on 47 tumor samples, and K-ras mutational status was examined on 85 tumor samples. For methylation analysis, a methylation specific PCR (MS-PCR) method was used. RESULTS: p16 and MGMT promoter methylation was found in 51% (24/47) and 43% (20/47) of CRCs, respectively, and the K-ras mutation was found in 44% (37/85) of CRCs. Comethylation of p16 and MGMT genes was significantly associated with lower aggressiveness of the disease within a two-year period of observation. Only 27% of patients with simultaneous p 16 and MGMT methylation showed the detectible occurrence of metastasis and/or death, compared to 67% of patients without double methylation or with no methylation (3/11 vs 22/33, P < 0.05, χ2-test). In addition, p16 and MGMT comethylation showed a trend toward an association with longer survival in patients with CRCs (35.5 ± 6.0 mo vs 23.1 ± 3.2 mo, P = 0.072, Log-rank test). Progression of the disease within a two-year period was observed in 66% of patients carrying the K-ras mutation, compared to only 19% of patients with wild type K-ras (29/44 vs 7/37, P < 0.001, χ2-test). The presence of the K-ras mutation significantly correlated to shortened overall survival (20.0 ± 1.9 mo vs 37.0 ± 1.8 mo, P < 0.001, Log-rank test). The comethylation of p16 and MGMT genes was significantly associated with lower aggressiveness of the disease even when K-ras mutations were included in the analysis as an independent variable. CONCLUSION: Our data suggest that comethylation of promoters of p 16 and MGMT genes could have a prognostic value in patients with CRC. Specifically, concurrent methylation of both genes correlates with better prognosis. | Koviljka Krtolica Milena Krajnovic Slavica Usaj-Knezevic Dragan Babic Dusan Jovanovic Bogomir Dimitrijevic | 2007 | World Journal of Gastroenterology2007,13,8: | 10 |
| 5 | Nitroglycerine effects on portal vein mechanics and oxidative stress in portal hypertension显示文摘AIM:Тo examine the effects of nitroglycerine on portal vein haemodynamics and oxidative stress in patients with portal hypertension.METHODS:Thirty healthy controls and 39 patients with clinically verified portal hypertension and increasedvascular resistance participated in the study.Liver di-ameters,portal diameters and portal flow velocities were recorded using color flow imaging/pulsed Doppler detection.Cross-section area,portal flow and index of vascular resistance were calculated.In collected blood samples,superoxide anion radical (O 2-),hydrogen per-oxide (H 2 O 2),index of lipid peroxidation (measured as TBARS) and nitric oxide (NO) as a marker of endothelial response (measured as nitrite-NO 2-) were determined.Time-dependent analysis was performed at basal state and in 10th and 15th min after nitroglycerine (sublingual 0.5 mg) administration.RESULTS:Oxidative stress parameters changed sig-nificantly during the study.H 2 O 2 decreased at the end of study,probably via O 2-mediated disassembling in Haber Weiss and Fenton reaction;O 2-increased signifi-cantly probably due to increased diameter and tension and decreased shear rate level.Consequently O 2-and H 2 O 2 degradation products,like hydroxyl radical,initi-ated lipid peroxidation.Increased blood flow was to some extent lower in patients than in controls due to double paradoxes,flow velocity decreased,shear rate decreased significantly indicating non Newtonian char-acteristics of portal blood flow.CONCLUSION:This pilot study could be a starting point for further investigation and possible implemen-tation of some antioxidants in the treatment of portal hypertension. | Andreja Vujanac Vladimir Jakovljevic Dusica Djordjevic Vladimir Zivkovic Mirjana Stojkovic Dragan Celikovic Nebojsa Andjelkovic Aleksandra Jurisic Skevin Dragan Djuric | 2012 | World Journal of Gastroenterology2012,18,4: | 7 |
| 6 | Diagnosis of Intermittent Connections for DeviceNet显示文摘An intermittent connection is one of the major problems that affect the network reliability and communication quality.However,little attention has been paid to the detection,analysis and localization of the intermittent connections.Partially due to the limitations of the DeviceNet protocol,there is no effective online diagnostic tool available to identify the location of intermittent connection.On the basis of different DeviceNet fault scenarios induced by intermittent connections,a new graph-based diagnostic method is developed to analyze DeviceNet fault patterns,identify the corresponding fault scenarios,and infer the location of the intermittent connection problem by using passively captured network faults.A novel error source analysis tool,which integrates network data-link layer analysis and feature based network physical layer information,is developed to restore the snapshots of the network communication at each intermittent connection induced error.A graph based location identification method is developed to infer the location of the intermittent connections based on the restored error patterns.A 3-node laboratory test-bed,using master-slave polling communication method,is constructed to emulate the intermittent connection induced faults on the network drop cable by using digital switches,whose on/off states are controlled by a computer.During experiments,the network fault diagnosis is conducted by using information collected on trunk cable(backbone).Experimental study shows that the proposed method is effective to restore the snapshots of the network errors and locate the drop cable that experiences the intermittent connection problem. | LEI Yong DJURDJANOVIC Dragan | 2010 | Chinese Journal of Mechanical Engineering2010,23,5: | 6 |
| 7 | How to treat an extensive form of primary intestinal lymphangiectasia?显示文摘We report a case of a 42-year-old man with a rare disorder known as primary intestinal lymphangiectasia,which is characterized by dilated intestinal lymphatics that lead to the development of protein-losing enteropathy. The patient presented with a grand mal seizure caused by malabsorption-derived electrolytes and a protein disorder. Signs of the disease, including chronic diarrhea and peripheral edema, manifested10 years ago, but a diagnosis was never made. The diagnosis was suspected because of the clinical manifestations, laboratory tests, imaging and endoscopic findings. Hyperemic and edematous mucosa of the small intestine corresponded to scattered white spots with dilated intestinal lymphatics and whitish villi in the histological specimen of the biopsied jejunal mucosa.Although numerous therapeutic strategies are available,only octreotide therapy proved to be an effective means of therapeutic resolution in this patient. Although the patient had a partial remission following the use of a slow release formula of octreotide, his prognosis, clinical course, and future treatment challenges are yet to be determined. | Rosana Troskot Dragan Jurcic Ante Bilic Marija Gomercic Palcic Stanko Tezak Ivana Brajkovic | 2015 | World Journal of Gastroenterology2015,21,23: | 6 |
| 8 | Suture granuloma of the abdominal wall with intra-abdominal extension 12 years after open appendectomy显示文摘Most complications after appendectomy occur within ten days; however, we report the unusual case of a suture granuloma 12 years after open appendectomy. The afebrile 75-year-old woman presented with a slightly painful palpable mass in the right lower abdomen. There was no nausea or vomiting and bowel movements were normal. She lost 10 kg during the 3 mo before presentation. The patient had undergone an appendectomy 12 years previously. Physical examination revealed a tender mass, 10 cm in diameter, under the appendectomy scar. The preoperative laboratory findings, tumor markers and plain abdominal radiographs were normal. Multi-slice computed tomography scanning showed an inhomo-genous abdominal mass with minimal vascularization in the right lower abdomen 8.6cm×8cm×9 cm in size which communicated with the abdominal wall. The abdominal wall was thickened, weak and bulging. The abdominal wall mass did not communicate with the cecum or the ascending colon. Complete excision of the abdominal wall mass was performed via median laparotomy. Histopathological examination revealed a granuloma with a central abscess. This case report demonstrates that a preoperative diagnosis of abdominal wall mass after open appendectomy warrants the use of a wide spectrum of diagnostic modalities and consequently different treatment options. | Goran Augustin Dragan Korolija Mate Skegro Jasminka Jakic-Razumovic | 2009 | World Journal of Gastroenterology2009,15,32: | 5 |
| 9 | Hepatitis C virus genotypes in Serbia and Montenegro: The prevalence and clinical signifi cance显示文摘AIM: To investigate the prevalence of hepatitis C virus (HCV) genotypes in Serbia and Montenegro and their in? uence on some clinical characteristics in patients with chronic HCV infection.METHODS: A total of 164 patients was investigated. Complete history, route of infection, assessment of al-cohol consumption, an abdominal ultrasound, standard biochemical tests and liver biopsy were done. Gene se-quencing of 5’ NTR type-specifi c PCR or commercial kits was performed for HCV genotyping and subtyping. The SPSS for Windows (version 10.0) was used for univariate regression analysis with further multivariate analysis. RESULTS: The genotypes 1, 2, 3, 4, 1b3a and 1b4 were present in 57.9%, 3.7%, 23.2%, 6.7%, 6.7% and 1.8% of the patients, respectively. The genotype 1 (mainly the subtype 1b) was found to be independent of age in sub-jects older than 40 years, high viral load, more severe necro-in? ammatory activity, advanced stage of fi brosis, and absence of intravenous drug abuse. The genotype 3a was associated with intravenous drug abuse and the age below 40. Multivariate analysis demonstrated age over 40 and intravenous drug abuse as the positive pre-dictive factors for the genotypes 1b and 3a, respectively. CONCLUSION: In Serbia and Montenegro, the geno-types 1b and 3a predominate in patients with chronic HCV infection. The subtype 1b is characteristic of older patients, while the genotype 3a is common in drug abus-ers. Association of the subtype 1b with advanced liverdisease, higher viral load and histological activity sug-gests earlier infection with this genotype and eventually its increased pathogenicity. | Neda Svirtlih Dragan Delic Jasmina Simonovic Djordje Jevtovic Ljubisa Dokic Eleonora Gvozdenovic Ivan Boricic Dragica Terzic Sladjana Pavic Gorana Neskovic Sonja Zerjav Vladimir Urban | 2007 | World Journal of Gastroenterology2007,13,3: | 5 |
| 10 | Increased activity of Pgp multidrug transporter in patients with Helicobacter pylori infection显示文摘AIM: To determine whether local antibiotic resistance involves P-glycoprotein (Pgp)-mediated active drug outpumping during Helicobacter pylori ( H pylori) infection treatment with classic antibiotic therapy. METHODS: Pgp activity was determined in gastric mucosa biopsy specimens obtained from 53 patients with pathohistologically verified gastritis and microbiologically confirmed H pylori infection, and compared with the Pgp activity in 12 control subjects with normal endoscopic findings. TheH pylori positive patients were treated with short-term 7-d therapy consisting of two antibiotics (amoxicillin and azithromycin/metronidazole and clarithromycin) and a proton pump inhibitor. Pgp activity was determined by flow cytometry in the test of rhodamine dye efflux and quantified as mean fluorescence ratio (RMF).RESULTS: Upon the first cycle,H pylori was successfully eradicated in 20 patients, whereas therapy was continued in 33 patients. In the course of antibiotic therapy, RMF increased (P<0.05) and gastric cells showed higher rhodamine dye efflux. The mean pre-treatment RMF values were also higher (P<0.0001) in patients with multiple therapeutic failure than in those with successful H pylorieradication and control subjects.CONCLUSION: Pgp might be one of the causes of therapy failure in patients with H pylori and antibiotic therapy could be chosen and followed up on the basis of the Pgp transporter local activity. | Zarko Babic Ivna Svoboda-Beusan Nastja Kucisec-Tepes Dragan Dekaris Rosana Troskot | 2005 | World Journal of Gastroenterology2005,11,18: | 4 |
| 11 | A resilience-based approach in managing the closure and abandonment of large mine tailing ponds显示文摘Mining tailing ponds are large infrastructure objects whose life cycle spans over several decades.They are indispensable for certain types of mines where technological process produces and rejects mud.They also have potential to generate risks for human life,property and environment.For that reason,it is essential to adequately manage them throughout all the stages of their life cycle.The phase of their closure and abandonment is less studied and understood.The paper proposes a holistic resilience-based approach for analyzing this phase of their life cycle.The proposed methodology is validated through a case study at an actual surface iron ore mine in Bosnia and Herzegovina. | Dragan Komljenovic Lazar Stojanovic Vladimir Malbasic Aleksandar Lukic | 2020 | International Journal of Mining Science and Technology2020,30,5: | 4 |
| 12 | Biochemical markers for non-invasive assessment of disease stage in patients with primary biliary cirrhosis显示文摘AIM: To evaluate different biochemical markers and their ratios in the assessment of primary biliary cirrhosis (PBC) stages. METHODS: This study included 112 patients with PBC who underwent a complete clinical investigation. We analyzed the correlation (Spearman's test) between ten biochemical markers and their ratios with different stages of PBC. The discriminative values were compared using areas under receiver operating characteristic (ROC) curves. RESULTS: The mean age of patients included in the study was 53.88 ± 10.59 years, including 104 females and 8 males. We found a statistically significant correlation between PBC stage and Aspartate aminotransferase (AST), Alanine aminotransferase (ALT) to platelet ratio (APRI), ALT/platelet count, AST/ALT, ALT/AST and ALT/Cholesterol ratios, with the values of Spearman's rho of 0.338, 0.476, 0.404, 0.356, 0.351 and 0.325, respectively. The best sensitivity and specificity was shown for AST/ALT, with an area under ROC of 0.660. CONCLUSION: Biochemical markers and their ratios do correlate with different sensitivity to and specificity of PBC disease stage. The use of biochemical markers and their ratios in clinical evaluation of PBC patients may reduce, but not eliminate, the need for liver biopsy. | Tamara Alempijevic Miodrag Krstic Rada Jesic Ivan Jovanovic Aleksandra Sokic Milutinovic Nada Kovacevic Slobodan Krstic Dragan Popovic | 2009 | World Journal of Gastroenterology2009,15,5: | 4 |

| 19 | 用传统和超声提取的松果菊(紫锥菊属)的抗氧化和抗菌活性(英文)显示文摘Antioxidant and antimicrobial activities of Echinacea purpurea L. (Asteraceae) extracts obtained by classical and ultrasound solvent extraction were compared. The dry aerial part of plant was extracted by 70% etha-nol at a solid-to-liquid ratio of 1︰10 (m/v) and 25°C. The extract obtained by classical solvent extraction contained 29% larger amounts of phenolic compounds and 20% higher content of flavonoids. 2,2-diphenyl-1-picril hydrazyl radical (DPPH) scavenging reached 93.6% and the values of EC50 were (34.16±0.65) μg·ml-1 and (65.48±1.12) μg·ml-1 for the extracts obtained by the classical and ultrasound extractions, respectively. The extracts, independent of the extraction technique applied, showed a considerable growth inhibition on Candida albicans and Saccharo-myces cerevisiae, while no growth inhibition zones were observed for Aspergillus niger. The diameters of inhibition zone observed for all the microorganisms were larger for extracts obtained by classical extraction than those by ul-trasound extraction. | Ivana Stanisavljevi Sаa Stojievi Dragan Velikovi Vlada Veljkovi Miodrag Lazi | 2009 | Chinese Journal of Chemical Engineering2009,17,3: | 2 |
