1Susceptibility variations of multiple origins of loess from the Ily Basin(NW China)显示文摘The magnetic susceptibility of loess from the Ily Basin,northwestern China shows maximum values in S0 paleosols but minimum values in other paleosols,the mechanism of which has been well debated.In this work,systematic magnetic measurements were made on a representative section from Neleke county.The results show that the loess horizons(L1,L2 and L3) have multi-domain magnetite grains of aeolian origin,S0 is characterized by production of pedogenetic ultrafine-grained ferrimagnetic minerals,and the other paleosols(S1,S2,and S3) are characterized by the formation of nonferrimagnetic minerals associated with waterlogging.The correlation between the low concentration of ferrimagnets,high paramagnetic content,high magnetic coercivity remanence,fine ferrimagnetic grain size and intensified pedogenesis suggest two competing processes of pedogenetic enhancement and pedogenetic depletion in the lower paleosols.Pedogenetic depletion dominates and is responsible for the low susceptibility.Changes in magnetic grain size distribution occur during pedogenetic depletion.The susceptibility variations are of multiple origins in the loess of the Ily Basin.Pedogenetic enhancement,pedogenetic depletion,and allochthonous input of magnetic minerals should all be taken into account to explain the variations of magnetic parameters.CHEN Qu LIU XiuMing HELLER F HIRT Ann M LU Bin GUO XueLian MAO XueGang ZHAO GuoYong FENG Hua GUO Hui 2012Chinese Science Bulletin2012,57,15:9

5Prediction of mortality among patients with chronic kidney disease:A systematic review显示文摘BACKGROUND Chronic kidney disease(CKD)is a common medical condition that is increasing in prevalence.Existing published evidence has revealed through regression analyses that several clinical characteristics are associated with mortality in CKD patients.However,the predictive accuracies of these risk factors for mortality have not been clearly demonstrated.AIM To demonstrate the accuracy of mortality predictive factors in CKD patients by utilizing the area under the receiver operating characteristic(ROC)curve(AUC)analysis.METHODS We searched Ovid MEDLINE,EMBASE,and the Cochrane Library for eligible articles through January 2021.Studies were included based on the following criteria:(1)Study nature was observational or conference abstract;(2)Study populations involved patients with non-transplant CKD at any CKD stage severity;and(3)Predictive factors for mortality were presented with AUC analysis and its associated 95%confidence interval(CI).AUC of 0.70-0.79 is considered acceptable,0.80-0.89 is considered excellent,and more than 0.90 is considered outstanding.RESULTS Of 1759 citations,a total of 18 studies(n=14579)were included in this systematic review.Eight hundred thirty two patients had non-dialysis CKD,and 13747 patients had dialysis-dependent CKD(2160 patients on hemodialysis,370 patients on peritoneal dialysis,and 11217 patients on non-differentiated dialysis modality).Of 24 mortality predictive factors,none were deemed outstanding for mortality prediction.A total of seven predictive factors[N-terminal pro-brain natriuretic peptide(NT-proBNP),BNP,soluble urokinase plasminogen activator receptor(suPAR),augmentation index,left atrial reservoir strain,C-reactive protein,and systolic pulmonary artery pressure]were identified as excellent.Seventeen predictive factors were in the acceptable range,which we classified into the following subgroups:predictors for the non-dialysis population,echocardiographic factors,comorbidities,and miscellaneous.CONCLUSION Several factors were found to predict mortality in CKD patients.Echocardiography is an important tool for mortality prognostication in CKD patients by evaluating left atrial reservoir strain,systolic pulmonary artery pressure,diastolic function,and left ventricular mass index.Panupong Hansrivijit Yi-Ju Chen Kriti Lnu Angkawipa Trongtorsak Max M Puthenpura Charat Thongprayoon Tarun Bathini Michael A Mao Wisit Cheungpasitporn 2021World Journal of Nephrology2021,10,4:2
