Bioenhanced degradation of toluene by layer-by-layer self-assembled silica-based bio-microcapsules.

In this study, micron-sized monodisperse SiO microspheres were used as sacrificial templates, and chitosan/polylactic acid (CTS/PLA) bio-microcapsules were produced using the layer-by-layer (LBL) assembly method. Microcapsules isolate bacteria from their surroundings, forming a separate microenvironment and greatly improving microorganisms' ability to adapt to adverse environmental conditions. Morphology observation indicated that the pie-shaped bio-microcapsules with a certain thickness could be successfully prepared through LBL assembly method.

Chemerin-9 Attenuates Experimental Abdominal Aortic Aneurysm Formation in ApoE Mice.

Chronic inflammation plays an essential role in the pathogenesis of abdominal aortic aneurysm (AAA), a progressive segmental abdominal aortic dilation. Chemerin, a multifunctional adipocytokine, is mainly generated in the liver and adipose tissue. The combination of chemerin and chemokine-like receptor 1 (CMKLR1) has been demonstrated to promote the progression of atherosclerosis, arthritis diseases, and Crohn's disease.

Protocol for a gallbladder cancer registry study in China: the Chinese Research Group of Gallbladder Cancer (CRGGC) study.

Introduction: Gallbladder cancer (GBC), the sixth most common gastrointestinal tract cancer, poses a significant disease burden in China. However, no national representative data are available on the clinical characteristics, treatment and prognosis of GBC in the Chinese population.

Methods And Analysis: The Chinese Research Group of Gallbladder Cancer (CRGGC) study is a multicentre retrospective registry cohort study.

Enhanced removal of NO-N from water using Fe-Al modified biochar: behavior and mechanism.

To remove NO-N from water, coconut shell biochar (CSB) was modified by a solution of FeCl, a solution of AlCl and a mixture solution of FeCl and AlCl respectively. The obtained modified biochar with the best effect of NO-N adsorption was screened out to explore the adsorption behavior and mechanism of NO-N removal by batch experiments and kinetics and thermodynamics and correlated characterization. The results indicated that the mixture solution of FeCl- and AlCl- modified CSB (Fe-Al/CSB) showed the best adsorption performance for NO-N removal.

Removal of NO-N in alkaline rare earth industry effluent using modified coconut shell biochar.

Coconut shell biochar (CSB) was selected as raw material to obtain two kinds of modified biochars by pickling and iron modification. The pickling coconut shell biochar (PCSB) and pickling-iron modified coconut shell biochar (PICSB) were used as adsorbents to remove NO-N in alkaline rare earth industry effluent. The results showed that pickling smoothed the surface of CSB, and α-FeOOH was formed on the surface of PCSB because of FeCl solution modification.

Diesel oil volatilization processes affected by selected porous media.

Volatilization plays an important role in attenuating petroleum products in contaminated soils. The objective of this study was to evaluate the influence of wind speed, vessel diameter and mean grain size of porous media on diesel oil volatilization. Experiments were conducted to investigate the volatilization behavior of diesel oil from porous media by weighing contaminated samples pre- and post-volatilization.

[Retrograde caudate lobectomy in 7 cases].

Objective: To explore the clinical value and significance of retrograde caudate lobectomy.

Methods: From December 2003 to January 2005, 7 patients underwent retrograde caudate lobectomy in which division and ligation of short hepatic veins were carried out at the final stage of the procedure in stead of at the initial stage.

Results: The procedures were carried out smoothly with no operative death in all the 7 cases including isolated complete caudate lobectomy in 4 cases, isolated partial caudate lobectomy in 1 case, combined right half liver resection in 2 case.

[Surgical treatment of hepatocellular carcinoma originating from caudate lobe].

Objective: To explore the significance of surgical treatment of HCC originating from caudate lobe.

Methods: From 1995 to 2003, caudate lobectomy, including 19 cases of isolated lobectomy and 20 cases of combined lobectomy, were performed in 39 patients with HCC originating from caudate lobe, and the factors that might influence postoperative liver function were compared between the two groups.

Results: All tumors were resected successfully.

Expression and significance of heparanase and nm23-H1 in hepatocellular carcinoma.

Aim: To explore the relation between heparanase (HPA) and nm23-H1 in hepatocellular carcinoma (HCC), and whether they could be used as valuable markers in predicting post-operative metastasis and recurrence of HCC.

Methods: Reverse transcription-polymerase chain reaction and immunohistochemistry (S-P method) were used to measure the expressions of HPA mRNA and nm23-H1 protein in primary tumor tissue and paracancerous tissue of 33 cases of HCC. Paracancerous tissues of 9 cases of benign liver tumor were used as normal controls.
