Effects of Alkali on Water Soluble Hexavalent Chromium in Ordinary Portland Cement.

Due to the toxicity and mobility of chromium, the disposal of chromium-containing waste is a pressing issue. Co-processing of chromium-containing waste in a cement kiln is currently one of the most effective methods. However, the presence of water-soluble hexavalent chromium (Cr(VI)) in cement limits the use of this method.

Arsenic and cadmium removal from water by a calcium-modified and starch-stabilized ferromanganese binary oxide.

A new calcium-modified and starch-stabilized ferromanganese binary oxide (Ca-SFMBO) sorbent was fabricated with different Ca concentrations for the adsorption of arsenic (As) and cadmium (Cd) in water. The maximum As(III) and Cd(II) adsorption capacities of 1% Ca-SFMBO were 156.25 mg/g and 107.

Transcriptomic analysis on the effects of melatonin in gastrointestinal carcinomas.

Background: Melatonin has been shown with anticancer property and therapeutic potential for tumors. However, there lacks a systematic study on the molecular pathways of melatonin and its antitumor effects in gastrointestinal carcinomas.

Methods: Using the gene expression profiles of four cancer cell lines from three types of gastrointestinal carcinomas before and after melatonin treatment, including gastric carcinoma (GC), colorectal carcinoma (CRC) and hepatocellular carcinoma (HCC), differentially expressed genes (DEGs) and biological pathways influenced by melatonin were identified.

Stabilization/solidification of chromium-bearing electroplating sludge with alkali-activated slag binders.

Chromium (Cr)-bearing electroplating sludge is a hazardous solid waste and has a detrimental effect on human health and the environment. In this study, an alkali-activated slag binders, namely, formed by the reaction of blast furnace slag (BFS) with alkali, was applied to the stabilization/solidification (S/S) of electroplating sludge. The effects of liquid-solid ratio, water glass modulus ratio (molar ratio of SiO to NaO), water glass dosage, and electroplating sludge amount on the compressive strength and Cr leachability of binders were analyzed.

Arsenic adsorption and removal by a new starch stabilized ferromanganese binary oxide in water.

A new starch stabilized ferromanganese binary oxide (starch-FMBO) with an Fe/Mn ratio of 1.00-2.00 and a synthetic pH of 2 was prepared using an organic polymer (starch) as the stabilizing dispersant.

A robust qualitative transcriptional signature for the correct pathological diagnosis of gastric cancer.

Background: Currently, pathological examination of gastroscopy biopsy specimens is the gold standard for gastric cancer (GC) diagnosis. However, it has a false-negative rate of 10-20% due to inaccurate sampling locations and/or insufficient sampling amount. A signature should be developed to aid the early diagnosis of GC using biopsy specimens even when they are sampled from inaccurate locations.

A qualitative signature for predicting pathological response to neoadjuvant chemoradiation in locally advanced rectal cancers.

Background And Purpose: The standard therapy for locally advanced rectal cancers (LARCs) is neoadjuvant chemoradiation (nCRT) followed by surgical resection. Pathological response to nCRT varies among patients, and it remains a challenge to predict pathological response to nCRT in LARCs.

Material And Methods: Using 42 samples as the training cohort, we searched a signature by screening the gene pairs whose within-sample relative expression orderings are significantly correlated with the pathological response.

[Isolation and characterization of a highly efficient BBP-degrading bacterium].

A bacterial strain HS-B1 which can utilize n-butyl benzyl phthalate as the sole source of carbon and energy was isolated from contaminated sludge in the Jinsha River of Hubei Province. Based on its morphology, physiological characteristic and 16S rDNA sequence analysis, HS-B1 was identified as Acinetobacter sp..
