Effect of DFP on the resorption from subcutaneous tissue

Kod trovanja diizopropilfluorofosfatom usporena je resorpcija sulfacetamida iz potkožnog tkiva u krv štakora zbog edema supkutanog tkiva. Davanje atropina ne normalizuje resorpciju sulfacetamida kod trovanja DFP-om. Ako se holinesteraza inhibirana DFP-om reaktivira sa TMB-4 ili PAM-2, onda više nema razlike u resorpciji kod zatrovanih i kontrolnih životinja. Od dva ispitana oksima TMB-4 i PAM-2, samo TMB-4 sam po sebi smanjuje resorpciju sulfacetamida iz potkožnog tkiva u krv, dok PAM-2 ne utiče na ovu resorpciju.In diisopropyl fluorophosphate rat poisoning the resorption of sulfacetamide from subcutaneous tissue into the blood is delayed owing to the oedema of subcutaneous tissue. The administration of atropine does not normalize the resorption of sulfacetamide in DFP poisoning. If cholinesterase inhibited by DFP is reactivated with TMB-4 or P AM-2, there is no longer any difference in resorption between poisoned and control animals. Out of the two oximes studies - TMB-4 and P AM-2 - only TMB-4 decreases the resorption of sulfacetamide from subcutaneous tissue into the blood, while PAM-2 has no effect on this resorption

Silhavy (Ed.), Applied Informatics and Cybernetics in Intelligent Systems: Proceedings of the 9th Computer Science On-line Conference, CSOC 2020 (pp. 108-126). (Advances in Intelligent Systems and Computing; Vol. 1226 AISC). Springer. https://doi.org/10.1007/978-3-030-51974-2_10For the past decades, organizations have been investing heavily in BPM projects in the hope of improving their competitive advantage in an increasingly complex environment. However, although it is believed that the higher the level of BPM maturity the greater the success of the organization, experience shows that this relationship is not always possible to prove. The purpose of this study is to help clarify the relationship between the level of BPM maturity and the success of an organization. This was done through the implementation of a case study-based research within a global company, focusing on the shared services organization. An analysis of the existing BPM maturity models and its level of coverage of BPM core areas was conducted to select the most suitable BPM maturity model to conduct the assessment of the current BPM maturity level. It was also established a framework to characterize the success of an organization. These two inputs, along with information gathered to understand implemented process improvements, were the basis for conducting the research. Results show a successful organization, with a high maturity level according to the BPM OMG maturity model, that has been investing in continually improving its processes with a strong focus on digital transformation. The identified benefits from a high level of BPM maturity, namely improved productivity, cost reduction, error & risk prevention, higher agility, employee upskilling and knowledge retention, were shown to have a positive influence in the majority of the dimensions used to characterize the success of the organization.authorsversionpublishe

Microarray and Proteomic Analyses of Myeloproliferative Neoplasms with a Highlight on the mTOR Signaling Pathway

The gene and protein expression profiles in myeloproliferative neoplasms (MPNs) may reveal gene and protein markers of a potential clinical relevance in diagnosis, treatment and prediction of response to therapy. Using cDNA microarray analysis of 25,100 unique genes, we studied the gene expression profile of CD34(+) cells and granulocytes obtained from peripheral blood of subjects with essential thrombocythemia (ET), polycythemia vera (PV) and primary myelofibrosis (PMF). The microarray analyses of the CD34(+) cells and granulocytes were performed from 20 de novo MPN subjects: JAK2 positive ET, PV, PMF subjects, and JAK2 negative ET/PMF subjects. The granulocytes for proteomic studies were pooled in 4 groups: PV with JAK2 mutant allele burden above 80%, ET with JAK2 mutation, PMF with JAK2 mutation and ET/PMF with no JAK2 mutation. The number of differentially regulated genes was about two fold larger in CD34(+) cells compared to granulocytes. Thirty-six genes (including RUNX1, TNFRSF19) were persistently highly expressed, while 42 genes (including FOXD4, PDE4A) were underexpressed both in CD34(+) cells and granulocytes. Using proteomic studies, significant up-regulation was observed for MAPK and PI3K/AKT signaling regulators that control myeloid cell apoptosis and proliferation: RAC2, MNDA, S100A8/9, CORO1A, and GNAI2. When the status of the mTOR signaling pathway related genes was analyzed, PI3K/AKT regulators were preferentially up-regulated in CD34(+) cells of MPNs, with down-regulated major components of the protein complex EIF4F. Molecular profiling of CD34(+) cells and granulocytes of MPN determined gene expression patterns beyond their recognized function in disease pathogenesis that included dominant up-regulation of PI3K/AKT signaling

Prevalence of human cytomegalovirus and Epstein-Barr virus in subgingival plaque at peri-implantitis, mucositis and healthy sites. A pilot study

This study evaluated the prevalence of human cytomegalovirus (HCMV) and Epstein-Barr virus (EBV) in peri-implantitis and mucositis sites and the correlation between herpesvirus and clinical parameters. Fifty-six dental implants (mean time of loading, 4.27 +/- 1.6 years) were evaluated (20 peri-implantitis, 18 mucositis, 18 healthy pen-implant sites.) The clinical parameters assessed were: visible plaque index (PI), bleeding on probing (BOP), suppuration (SUP), probing depth (PD). A polymerase chain reaction assay identified HCMV and EBV in subgingival plaque samples. The percent of sites with plaque and BOP was significantly higher around mucositis and peri-implantitis compared with healthy implants (p lt 0.05). The mean PD around the implants was significantly higher in peri-implantitis, followed by mucositis and healthy implants (p lt 0.05). HCMV was detected in 13 (65%) and EBV in 9 (45%) of the 20 peri-implantitis sites. HCMV was found in 1 of the 18 (6%) healthy periodontal sites and EBV in 2 (11 %). A statistically significant correlation was found between presence of HCMV and EBV subgingivally and clinical parameters of peri-implantitis and healthy sites. These results confirm the high prevalence of HCMV and EBV in subgingival plaque of peri-implantitis sites and suggest the viruses have a possible active pathogenic role in peri-implantitis

Correlation between different genotypes of human cytomegalovirus and Epstein-Barr virus and peri-implant tissue status

Background: The purpose of this study was to estimate the prevalence of different genotypes of human cytomegalovirus (HCMV) and Epstein-Barr virus (EBV) in peri-implantitis and mucositis sites, and to evaluate the correlation between herpesvirus presence and clinical parameters. Methods: A total of 80 dental implants ( mean time of loading, 4.16 +/- 1.8 years) were evaluated during the course of the study (30 peri-implantitis, 25 mucositis and 25 healthy peri-implant sites). The following clinical parameters were assessed: visible plaque index, bleeding on probing, suppuration and probing depth. A polymerase chain reaction (PCR) assay was used to identify the presence of different HCMV and EBV genotypes in peri-implant tissue plaque samples. Results: HCMV-2 was detected in 53.3% and EBV-1 in 46.6% of the 30 peri-implantitis sites evaluated. By contrast, HCMV-2 was not detected in healthy periodontal sites and EBV-1 was detected in one healthy site. A statistically significant correlation was found between the presence of HCMV-2 and EBV-1 genotypes and clinical parameters of peri-implantitis. Conclusions: The results from the present study confirmed the high prevalence of HCMV-2 and EBV-1 in the peri-implant tissue plaque of peri-implantitis sites and suggests a possible active pathogenic role of the viruses in peri-implantitis

Assessment of quality of life and physical and mental health in children and adolescents with coeliac disease compared to their healthy peers

© 2019, Serbia Medical Society. All rights reserved. Introduction/Objective Strict gluten-free diet for life is the only treatment for patients with coeliac disease. Limited selection of food options can affect their quality of life and cause problems in acceptance by their peers. The aim was to examine the subjective quality of life experience in children and adolescents with coeliac disease and to obtain a comprehensive representation of physical and mental impairments and social functioning compared to their healthy peers. Methods The study was conducted as a cross-sectional study. It included 116 respondents aged 5-18 years with coeliac disease and 116 healthy children of similar age and sex. A Serbian version of Pediatric Quality of Life Inventory (PedsQL) was used to measure the quality of life in children. Descriptive statistics were calculated to analyze all results, while t-test was used to compare them. Results The mean value of total PedsQL score was lower in the coeliac disease patients (75.89 ± 20.35) than in the controls (86.35 ± 11.13). Additionally, the experimental group reported lower all PedsQL Scale scores than the control group in the domains of psychosocial, school, social, and emotional functioning. However, there was no statistically significant difference on the physical health scale. These results were the same in all age groups among both males and females. Conclusions The disturbance of health-related quality of life in children and adolescents with coeliac disease is significant and the quality of life is lower if compared to their healthy peers

Influence of breastfeeding and timing of gluten introduction on the onset of celiac disease in infants

© 2019, Serbia Medical Society. All rights reserved. Introduction/Objective The classic type of celiac disease (CD) is most common in children under two years of age. The aim of this study was to investigate whether breastfeeding, particularly breastfeeding during gluten introduction, and timing of gluten introduction, influence the onset of CD at this age. Methods We retrospectively analyzed medical records of 93 children, 40 in the first and 53 in the second year, with a classic CD diagnosed at the University Children’s Hospital, Belgrade between 2000 and 2010. The diagnosis of CD was based on the criteria of the European Society for Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) from 1989. Results Duration of breastfeeding reduced the onset of the CD in the first year p = 0.039 (OR = 1.43 95% CI 1.019–1.899). Also, breastfeeding at the time of gluten introduction significantly delayed the age at diagnosis (F = 1.671, t = 2.39, p = 0.029). The timing of gluten introduction did not affect the age of occurrence of CD in these group of children. Conclusion Longer breastfeeding, and breastfeeding at the time of gluten introduction, postponed the onset of classic CD in patients up to two years. The association between the occurrence of CD and the time of introduction of gluten in this age group of patients has not been established

HLA genotyping in pediatric celiac disease patients

© 2014 ABMSFBIH Celiac disease (CD) is a chronic inflammatory disease in the small intestine triggered by gluten uptake that occurs in genetically susceptible individuals. HLA-DQ2 protein encoded by HLA-DQA1*05 and DQB1*02 alleles is found in 90-95% of CD patients. All of the remaining patients carry HLA-DQ8 protein encoded by HLA-DQA1*03 and DQB1*03:02 alleles. Specific HLA-DQ genotypes define different risk for CD incidence. Presence of susceptible HLA-DQ genotypes does not predict certain disease development, but their absence makes CD very unlikely, close to 100%. Here we presented for the first time the distribution of HLA-DQ genotypes in the group of pediatric celiac patients from the University Children’s Hospital, Belgrade, Serbia and estimated risk for CD development that these genotypes confer. Seventy three celiac disease patients and 62 healthy individuals underwent genotyping for DQA1, DQB1 alleles and DRB1 allele. 94.5% of patients carried alleles that encode DQ2 protein variant and 2.7% carried alleles that encode DQ8 protein variant. Two patients carried single DQB1*02 allele. No patients were negative for all the alleles predisposing to CD. The highest HLA-DQ genotype risk for CD development was found in group of patients homozygous for DQ2.5 haplotype, followed by the group of heterozygous carriers of DQ2.5 haplotype in combination with DQB1*02 allele within the other haplotype. The lowest risk was observed in carriers of a single copy of DQB1*02 or DQA1*05 allele or other non-predisposing alleles. HLA genotyping, more informative than serological testing commonly used, proved to be a useful diagnostic tool for excluding CD development
