Multi-scale failure mechanisms of hydraulic engineering exposed to seasonally frozen salinization environment: Integrating SBAS-InSAR and mechanical experiments.

Constructing hydraulic engineering ensures agricultural development and improves salinization environments. However, in seasonally frozen salinization regions, hydraulic engineering is prone to deformation failure. Leakage from canal raises the regional groundwater level, triggering secondary salinization environmental issues.

Induction of mouse totipotent stem cells by a defined chemical cocktail.

In mice, only the zygotes and blastomeres from 2-cell embryos are authentic totipotent stem cells (TotiSCs) capable of producing all the differentiated cells in both embryonic and extraembryonic tissues and forming an entire organism. However, it remains unknown whether and how totipotent stem cells can be established in vitro in the absence of germline cells. Here we demonstrate the induction and long-term maintenance of TotiSCs from mouse pluripotent stem cells using a combination of three small molecules: the retinoic acid analogue TTNPB, 1-azakenpaullone and the kinase blocker WS6.

Study on Start-Up Membraneless Anaerobic Baffled Reactor Coupled with Microbial Fuel Cell for Dye Wastewater Treatment.

In this study, the antitoxicity performance of the traditional anaerobic baffled reactor (ABR) and the newly constructed membraneless anaerobic baffled reactor coupled with microbial fuel cell (ABR-MFC) was compared for the treatment of simulated printing and dyeing wastewater under the same hydraulic residence time. The sludge performances of ABR-MFC and ABR were evaluated on the dye removal rate, extracellular polymer (EPS) content, sludge particle size, methane yield, and the surface morphology of granular sludge. It was found that the maximum power density of the ABR-MFC reactor reached 1226.

Hemorheological changes in patients with living-donor renal transplantation.

Living-donor renal transplantation is the preferred treatment for patients with end stage renal disease since it affords earlier transplantation and better graft for long term survival. The aim of the present study was to explore the hemorheological changes in patients undergone living-donor renal transplantation. We investigated the dynamic changes in the hemorheological properties of blood taken from the patients before renal transplantation and at 1 week, 2 week, 3 week and >1 month after the operation.

[Up-regulation of the sHLA-G5 level by human-mouse chimeric anti-IL-2R monoclonal antibody treatment in kidney transplantation].

Objective: To find whether the up-regulation of soluble human leucocyte antigen-G5 (sHLA-G5) levels is a new function mechanism of anti-interleukin-2 receptors (anti-IL-2R) monoclonal antibody treatment in kidney transplantation.

Methods: A total of 215 recipients at our centre from January 2006 to December 2007 were divided into antibody use group (n = 141) and antibody non-use group (n = 74) and another healthy group (n = 69). The sHLA-G5 level in peripheral blood was detected by enzyme-linked immunosorbent assay (ELISA).

[Applications of monitoring human leukocyte antigen G and its inhibitory receptors in post-renal transplantation].

Objective: to study the feasibility of human leucocyte antigen-G (HLA-G) as a post-transplantation prognostic biomarker and discuss the correlation of its receptor expression and the mechanisms.

Methods: a total of 215 recipients in our centre from February 2006 to June 2008 were divided into stable kidney function group (n = 173) and acute rejection group (n = 42). The soluble human leucocyte antigen-G5 (sHLA-G5) level in peripheral plasma was detected by ELISA.

[Pathogenesis of post-transplantation diabetes mellitus in 40 renal transplantation recipients].

Objective: To explore pathogenesis of post-transplantation diabetes mellitus (PTDM) in renal transplantation recipients.

Methods: A total of 40 renal transplantation recipients were divided into three groups based on oral glucose tolerance test results: normal glucose tolerance (NGT) group (n = 10), impaired fasting glycaemia + impaired glucose tolerance (IFG + IGT) group (n = 16), and PTDM group (n = 14). Insulin resistance (IR) and beta cell function were assessed by homeostasis model.

[Risk factors of long-term cardiovascular diseases and cerebrovascular diseases in kidney allograft recipients].

Objective: To identify the risk factors of cardiovascular diseases and cerebrovascular diseases (CVD) events in kidney allograft recipients.

Methods: We followed up 361 renal transplant recipients who had undergone renal transplantation in our center from January 2000 to December 2003 and evaluated the cumulative incidences and mortalities of CVD complications at baseline and post-transplantation 1, 3, 6, 12, 24, 36, 48, and 60 months. Kaplan-Meier plot was used to assess the incidence and Cox's proportional hazards model to determine the risk factors for cardiovascular complications.
