2Serum immunoglobulin A concentration is a reliable biomarker for liver fibrosis in non-alcoholic fatty liver disease显示文摘AIM:To evaluate the diagnostic accuracy of serum Immunoglobulin A(IgA)for differentiating early stage nonalcoholic fatty liver disease(NAFLD)from nonalcoholic steatohepatitis(NASH).METHODS:All cases had fatty liver change confirmed by ultrasound and aminotransferases of at least twice the normal level.Clinical and biochemical data,including serum IgA,were obtained from 50 histologically proven NAFLD cases and 54 healthy controls.Fasting whole blood samples were obtained from the study population.Immunoturbidimetric methods were used to measure the IgA levels.All NAFLD cases were hospitalized for liver biopsy.Liver specimens were examined for steatosis,steatohepatitis and fibrosis within hepatocytes.Patients were categorized into two groups:NASH and non-NASH.Variables were compared within cases(NASH vs non-NASH)and controls.Cut-off values of serum IgA were evaluated using analysis of receiver operating characteristic(ROC curves).Associations between the variables were tested using calculations of correlation coefficients.Statistical significances were assigned to P values<0.05.RESULTS:The extent of liver fibrosis correlated positively with IgA levels.Subjects with no fibrosis in their liver biopsies had a lower IgA level(301.5±91.2 mg/dL)than subjects with any degree of fibrosis(388.8±140.8 mg/dL),(P=0.01).IgA levels were higher in NASH cases,and its value was significantly higher for higher degrees of fibrosis.Patients with perisinusoidal or pericellular fibrosis had significantly higher levels of IgA(403.5±133.9 mg/dL,418.2±129.5 mg/dL)compared to those without it(301.8±94.9 mg/dL,297.7±91.5 mg/dL),respectively.No significant correlation was found between steatosis grade and serum IgA levels.Based on ROC analysis,the best predictive IgA cutoff value for detecting liver fibrosis was 360mg/dL(61%sensitivity,81%specificity).CONCLUSION:The serum IgA level is useful to evaluate the severity of liver fibrosis and can be used serially for evaluation and follow-up of NAFLD cases.Iradj Maleki Mahmood Reza Aminafshari Tarang Taghvaei Vahid Hosseini Alireza Rafiei Zhila Torabizadeh Maryam Barzin Elahe Orang 2014World Journal of Gastroenterology2014,20,35:4

5Wavelet-based iterative data enhancement for implementation in purification of modal frequency for extremely noisy ambient vibration tests in Shiraz-Iran显示文摘The main purpose of the present study is to enhance high-level noisy data by a wavelet-based iterative filtering algorithm for identification of natural frequencies during ambient wind vibrational tests on a petrochemical process tower.Most of denoising methods fail to filter such noise properly.Both the signal-to-noise ratio and the peak signal-to-noise ratio are small.Multiresolution-based one-step and variational-based filtering methods fail to denoise properly with thresholds obtained by theoretical or empirical method.Duc to the fact that it is impossible to completely denoise such high-level noisy data,the enhancing approach is used to improve the data quality,which is the main novelty from the application point of view here.For this iterative method,a simple computational approach is proposed to estimate the dynamic threshold values.Hence,different thresholds can be obtained for different recorded signals in one ambient test.This is in contrast to commonly used approaches recommending one global threshold estimated mainly by an empirical method.After the enhancements,modal frequencies are directly detected by the cross wavelet transform(XWT),the spectral power density and autocorrelation of wavelet coefficients.Estimated frequencies are then compared with those of an undamaged-model,simulated by the finite element method.Hassan YOUSEFI Alireza TAGHAVI KANI Iradj MAHMOUDZADEH KANI Soheil MOHAMMADIA 2020Frontiers of Structural and Civil Engineering2020,14,2:1

8Adaptive simulation of wave propagation problems including dislocation sources and random media显示文摘An adaptive Tikhonov regularization is integrated with an h-adaptive grid-based scheme for simulation of elastodynamic problems, involving seismic sources with discontinuous solutions and random media. The Tikhonov method is adapted by a newly-proposed detector based on the MINMOD limiters and the grids are adapted by the multiresolution analysis (MRA) via interpolation wavelets. Hence, both small and large magnitude physical waves are preserved by the adaptive estimations on non-uniform grids. Due to developing of non-dissipative spurious oscillations, numerical stability is guaranteed by the Tikhonov regularization acting as a post-processor on irregular grids. To preserve waves of small magnitudes, an adaptive regularization is utilized: using of smaller amount of smoothing for small magnitude waves. This adaptive smoothing guarantees also solution stability without over smoothing phenomenon in stochastic media. Proper distinguishing between noise and small physical waves are challenging due to existence of spurious oscillations in numerical simulations. This identification is performed in this study by the MINMOD limiter based algorithm. Finally, efficiency of the proposed concept is verified by: 1) three benchmarks of one-dimensional (1-D) wave propagation problems;2) P-SV point sources and rupturing line-source including a bounded fault zone with stochastic material properties.Hassan YOUSEFI Jamshid FARJOODI Iradj MAHMOUDZADEH KANI 2019Frontiers of Structural and Civil Engineering2019,13,5:1
