Co-melting mechanisms for municipal solid waste incineration fly ash with fine slag from coal gasification and coal gangue.

Vitrification is a promising treatment for municipal solid waste incineration fly ash (MSWI-FA); however, high energy consumption due to the high MSWI-FA fusion temperature limits the development and application of this technique. In this study, fine slag ash (FSA) derived from coal gasification and coal gangue ash (CGA) were mixed with MSWI-FA to reduce the ash fusion temperature. The transformation of minerals in ash during thermal treatment was examined via X-ray diffraction and thermodynamic equilibrium calculations.

Integrated Transcriptomic and Metabolomic Analysis of Exogenous NAA Effects on Maize Seedling Root Systems under Potassium Deficiency.

Auxin plays a crucial role in regulating root growth and development, and its distribution pattern under environmental stimuli significantly influences root plasticity. Under K deficiency, the interaction between K transporters and auxin can modulate root development. This study compared the differences in root morphology and physiological mechanisms of the low-K-tolerant maize inbred line 90-21-3 and K-sensitive maize inbred line D937 under K-deficiency (K = 0.

The current methods of treating organic waste suffer from limited resource usage and low product value. Research and development of value-added products emerges as an unavoidable trend for future growth. Electro-fermentation (EF) is a technique employed to stimulate cell proliferation, expedite microbial metabolism, and enhance the production of value-added products by administering minute voltages or currents in the fermentation system.

Anaerobic fermentation of organic solid waste: Recent updates in substrates, products, and the process with multiple products co-production.

The effective conversion and recycling of organic solid waste contribute to the resolution of widespread issues such as global environmental pollution, energy scarcity and resource depletion. The anaerobic fermentation technology provides for the effective treatment of organic solid waste and the generation of various products. The analysis, which is based on bibliometrics, concentrates on the valorisation of affordable and easily accessible raw materials with high organic matter content as well as the production of clean energy substances and high value-added platform products.

Improving lactic acid yield of hemicellulose from garden garbage through pretreatment of a high solid loading coupled with semi-hydrolysis using low enzyme loading.

Byproduct (acetate and ethanol) generation and carbon catabolite repression are two critical impediments to lactic acid production from the hemicellulose of lignocellulosic biomass. To reduce byproduct generations, acid pretreatment with high solid loading (solid-liquid ratio 1:7) of garden garbage was conducted. The byproduct yield was only 0.

Long-term clinical safety and efficacy of drug-coated balloon in the treatment of in-stent restenosis: A meta-analysis and systematic review.

Objectives: The aim of this study was to evaluate the long-term clinical safety and efficacy of drug-coated balloon (DCB) in the treatment of in-stent restenosis (ISR).

Background: There is a long-term safety issue in peripheral arterial disease patients treated with paclitaxel-coated balloon, this has also raised concerns on DCB in coronary intervention.

Methods: Nine randomized controlled trials (RCTs) and nine observational studies (OSs) were included with a total of 3,782 patients (1,827 in the DCB group, 1,955 in the drug-eluting stent [DES] group) being analyzed.

Degradation of acetaminophen with ferrous/copperoxide activate persulfate: Synergism of iron and copper.

To enhance the advanced oxidation process based on persulfate, CuO was introduced into the Fe/PS system to achieve a synergistic effect between Fe and Cu. Results showed that Fe was able to adsorb onto the CuO surface to form Fe(II) and further reduced Cu(II) into Cu(I), which can further release into the solution to participate in oxidation reactions. In this case, SO can be generated via Fe and Cu reactions with PS and ·OH from Cu reaction with dissolved oxygen (DO).

[Generation and release of Microcystin-lR by Microcystis aeruginosa under hydroquinone inhibition].

The generation and release of algal toxin Microcystin-LR (MCLR), as well as the intracellular organic chemicals were studied during the inhibition processes of Microcystis aeruginosa using hydroquinone as the inhibitor. According to the dose-effect relationship, the corresponding dosages of EC20, EC50, EC70, EC90, EC99 were added to the algae suspension. The TOC was determined by the total organic carbon analyzer, and the three-dimensional fluorescence spectrum was obtained by the fluorescence spectrophotometer.

Flocculation of Microcystis aeruginosa using modified larch tannin.

To flocculate the cyanobacterium Microcystis aeruginosa from water, larch tannin, a natural polymer, was modified by Mannich reaction to obtain a flocculant, named A-TN, which was then quaternized to yield another flocculant, named Q-TN. A-TN and Q-TN were characterized by Fourier transform infrared spectra (FTIR) and zeta potential analysis. The effects of the flocculation parameters, e.

Specific expression of osteopontin and S100A6 in hepatocellular carcinoma.

Background: Our aim was to identify differential expression of genes in hepatocellular carcinoma (HCC) with the ultimate goal of discovering novel diagnostic and therapeutic targets.

Methods: We examined differences in gene expression between HCC and noncancerous liver tissue using a cDNA array with probes for 15,843 genes/clones. Two genes, osteopontin (OPN) and S100A6, were found to be >10-fold differentially expressed, and were selected for further immunohistochemical staining in 51 HCC and 10 nonmalignant liver specimens.

Objective: To investigate the hematological changes and related gene mutation of post-severe acute respiratory syndrome (SARS) patients with osteonecrosis so as to find the sensitive molecular symbols for early screening of the high risk populations.

Methods: Fast peripheral venous blood samples were collected from 61 post-SARS patients with osteonecrosis, 25 males and 36 females, aged 30.4 (20 - 60), and 52 sex and age-matched healthy persons as controls.

Changes in coagulation and fibrinolysis of post-SARS osteonecrosis in a Chinese population.

The purpose of this study was to detect changes in coagulation and fibrinolysis of post-severe acute respiratory syndrome (SARS) Chinese patients with osteonecrosis, investigate the aetiology of post-SARS osteonecrosis (ON), and select the sensitive molecular markers for identifying the susceptible population.
