    Objectives: To investigate maternal serum ghrelin levels in pregnancies complicated by preeclampsia and to explore the relationship between ghrelin level and disease severity. Materials and methods: This case-control study included 40 healthy pregnant women, 42 women with mild preeclampsia, and 40 women with severe preeclampsia. The groups were matched in terms of maternal and gestational age and body mass index. Serum ghrelin levels were measured via enzyme immunoassay. Results: Serum ghrelin levels were significantly higher in women with mild and severe preeclampsia than in healthy controls (p < 0.001). Although serum ghrelin levels were somewhat higher in the severe compared to the mild preeclampsia group, the difference was not statistically significant (p > 0.05). In the control group, no significant correlation was observed between ghrelin level and any other parameter, but in the preeclampsia group, serum ghrelin levels were negatively correlated with uterine artery Doppler index values and both systolic and diastolic blood pressure (all p-values < 0.05). Multivariate stepwise linear regression analysis revealed that systolic blood pressure (β = 0.493, p = 0.023) was independently associated with serum ghrelin level. Conclusion: Elevated blood ghrelin levels were correlated with disease severity in pregnancies complicated by preeclampsia.Cel pracy: Ocena poziomu greliny w surowicy kobiet w ciąży powikłanej stanem przedrzucawkowym i określenie związku między poziomem greliny a ciężkością choroby. Materiał i metoda: Do badania włączono 40 zdrowych kobiet w ciąży, 42 z łagodnym stanem przedrzucawkowym i 40 z ciężkim stanem przedrzucawkowym. Grupy były dobrane pod względem wieku ciążowego, wieku matek i wskaźnika masy ciała. Poziom greliny w surowicy był mierzony metodą immunoenzymatyczną. Wyniki: Poziom greliny w surowicy był istotnie wyższy u kobiet z łagodnym i ciężkim stanem przedrzucawkowym niż w grupie kontrolnej (p < 0,001). Chociaż poziom greliny w surowicy był wyższy w grupie z ciężkim stanem przedrzucawkowym niż w grupie z łagodnym stanem przedrzucawkowym, to ta różnica nie była istotna statystycznie (p > 0,05). W grupie kontrolnej nie obserwowano żadnych istotnych związków pomiędzy poziomem greliny a jakimkolwiek innym parametrem, ale w grupie ze stanem przedrzucawkowym poziom greliny w surowicy był ujemnie skorelowany z indeksami przepływów Dopplera w tętnicy macicznej oraz ciśnieniem krwi skurczowym i rozkurczowym (all p-values < 0,05). Wieloczynnikowa analiza regresji liniowej wykazała, że skurczowe ciśnienie krwi było niezależnym czynnikiem związanym z poziomem greliny w surowicy (β = 0,493, p = 0,023). Wnioski: Podwyższony poziom greliny we krwi był związany z ciężkością choroby w ciążach powikłanych stanem przedrzucawkowym

    A linear programming-based method for job shop scheduling

    Get PDF
    We present a decomposition heuristic for a large class of job shop scheduling problems. This heuristic utilizes information from the linear programming formulation of the associated optimal timing problem to solve subproblems, can be used for any objective function whose associated optimal timing problem can be expressed as a linear program (LP), and is particularly effective for objectives that include a component that is a function of individual operation completion times. Using the proposed heuristic framework, we address job shop scheduling problems with a variety of objectives where intermediate holding costs need to be explicitly considered. In computational testing, we demonstrate the performance of our proposed solution approach

    In this study, the cyanido complexes given by the formula [Ni(Abut)Ni(CN)4]·8H2O (C1), [Cu(Abut)2Ni(CN)4]·7H2O (C2), [Zn(Abut)Ni(CN)4]·8H2O (C3) and [Cd(Abut)Ni(CN)4]·7H2O (C4) were obtained by microwave synthesis method. The powder forms of the complexes were characterized by elemental, FT-IR spectroscopy, and thermal analysis. And also antibacterial, antibiofilm and anticancer activities were investigated. The splitting stretching bands of cyanido groups in the FT-IR spectra of C1-C4 indicated the assets of terminal and end cyanido groups. The antibacterial activities of C1-C4 were tested with nine Gram negative and six Gram positive bacteria. The most efficient antibacterial activity of complexes was observed at 1000 µg/ml-1 concentration. Anticancer activity was tested using HeLa cell line and MTT test. The studied cyanide complexes have been shown to decrease the viability of HeLa cells with IC50 values 14.86, 6.5, 7.2 and 19.2 µg/ml for C1, C2, C3 and C4 complex, respectively

    The treatment of acute bronchitis [Akut bronşit tedavisi]

    No full text
    Acute bronchitis is a common clinical disorder characterized by acute inflammation of tracheobronchial tree. Viruses (influenza, respiratory syncytial virus, adeovirus etc.) are the most common etiologic agents. Bacterial agents, especially Mycoplasma pneumoniae, Chlamydia pneumoniae and Bordatella pertussis rarely cause acute bronchitis. Because the disorder is mostly caused by viral agents, treatment is usually symptomatic. Antitussive, protussive and bronchodilatator drugs can be used, but routine antibiotic treatment Is not recommended in uncomplicated acute bronchitis

    Diagnostic value of perinatal autopsies: Analysis of 486 cases

    Aim: Autopsy is a beneficial procedure to determine the cause of death and the frequency of anomalies in perinatal losses. Even in the event of an autopsy not providing any additional information, completion of the procedure confirming the clinical diagnoses gives reassurance to both clinicians and parents. Here we present a 15-year archival study based on findings of perinatal autopsies. Design and methods: Four hundred and eighty-six cases from our archive were reviewed and according to the findings they were divided into three subcategories; (1) miscarriages (MCF); (2) fetuses terminated (FTA) for vital anomalies detected by prenatal ultrasonography; (3) premature or term newborns died within first month of life (neonates: NN). Autopsies were documented and classified according to week/age of cases, anomalies and causes of abortion or death. Results: Two hundred and twenty-six of 486 cases (46.5%) were in MCF group while 227 (46.7%) and 33 (6.8%) were of them in FTA and NN groups, respectively. In FTA group, the most frequent anomaly detected was neural tube defects. In NN group, prematurity related complications were the most common cause of death. The autopsy process was found valuable in 39.7% of all cases. Conclusions: We suggest that autopsy procedure is diagnostically valuable even in situations when there is USG findings that are confirming FTAs or there is no important major fetal or placental anomaly detected in MCFs. © 2018 Walter de Gruyter GmbH, Berlin/Boston
