Characteristics of the pyrolytic products and the pollutant emissions at different operating stages from a pilot waste tire pyrolysis furnace.

Pyrolysis is considered a highly practical, cost-effective, and environment-friendly technology for waste tires disposal. In this study, pyrolysis processes of waste tires were conducted in a pilot scale furnace feeding at 30 kg/h. The properties of pyrolytic products and the distribution patterns of pollutants generated in different operating stages (start-up, steady, and shut-down) were investigated.

AjTGFβ alleviates V. splendidus-induced inflammation through SMADs pathway in Apostichopus japonicus.

The inhibition of inflammatory response is an essential process to control the development of inflammation and is an important step to protect the organism from excessive inflammatory damage. As a pleiotropic cytokine, transforming growth factor beta (TGF-β) plays a regulatory role in inhibiting inflammation in vertebrates. To investigate the role of TGF-β in the regulation of inflammation in invertebrates, we cloned and characterized the TGF-β gene from Apostichopus japonicus via rapid amplification of cDNA ends, and the sample was designated as AjTGF-β.

Formation behavior of PAHs during pyrolysis of waste tires.

Polycyclic aromatic hydrocarbons (PAHs) formation from the pyrolysis of waste tires is inevitable because of the complexity of tire formulations and the addition of certain chemicals. In this study, the formation behavior and distribution of PAHs in three-phases were investigated from waste tires under pyrolysis conditions. The influencing factors including the temperature, heating rate, holding time, particle size, catalyzer, and atmosphere, were systematically evaluated.

Dioxin emission and distribution from cement kiln co-processing of hazardous solid waste.

Cement kiln collaborative disposal technology can not only dispose of hazardous waste but also provide energy for the cement industry. However, the addition of hazardous waste may promote the formation of dioxins in cement kilns. In this study, typical hazardous solid wastes, such as solidified fly ash, electroplating sludge, and industrial residue, were co-processed in a cement kiln with different feeding positions and different feeding amounts.

Pulsed Electromagnetic Field Attenuates Osteoarthritis Progression in a Murine Destabilization-Induced Model through Inhibition of TNF-α and IL-6 Signaling.

Objective: To investigate the anti-inflammatory effects and mechanisms of pulsed electromagnetic field (PEMF) in the treatment of osteoarthritis (OA) in the destabilization of the medial meniscus (DMM) mice.

Design: Ten-week-old male wild-type (WT), interleukin (IL)-6 and tumor necrosis factor (TNF)-α mice undergoing DMM surgery were randomly divided into 2 groups ( = 10 each): mice with PEMF exposure and mice with sham PEMF exposure. PEMF (75 Hz, 3.

Modification of activated carbon using urea to enhance the adsorption of dioxins.

Activated carbon is commonly used to remove dioxins from flue gas via adsorption. Improving the targeted adsorption capacity of activated carbon for dioxins can reduce the consumption of adsorbents and help achieve emission standards for target pollutants. Here, commercial coal-based activated carbon was used as a raw material and modified by urea impregnation along with treatment at high temperature under a nitrogen atmosphere.

Application of neural network model in assisting device fitting for low vision patients.

Background: To explore the application of neural network models in artificial intelligence (AI)-aided devices fitting for low vision patients.

Methods: The data of 836 visually impaired people were collected in southwestern Fujian from May 2014 to May 2017. After a full eye examination, 629 low vision patients were selected from this group.

Causes of vision loss at China's largest blind school during a period of significant economic growth: 2008-2016.

Purpose: To investigate the different causes of vision loss and school-based treatment regimens at Quanzhou Blind School (QBS), China's largest blind school, in 2008 and 2016.

Methods: In 2008, 144 students received comprehensive eye examinations along with a complete family and ophthalmic history; in 2016, 125 students were examined. Vision loss was categorized into visual impairment and blindness classifications based on WHO guidelines.

Pulsed Electromagnetic Field Versus Whole Body Vibration on Cartilage and Subchondral Trabecular Bone in Mice With Knee Osteoarthritis.

Pulsed electromagnetic field (PEMF) and whole body vibration (WBV) interventions are expected to be important strategies for management of osteoarthritis (OA). The aim of the study was to investigate the comparative effectiveness of PEMF versus WBV on cartilage and subchondral trabecular bone in mice with knee OA (KOA) induced by surgical destabilization of the medial meniscus (DMM). Forty 12-week-old male C57/BL mice were randomly divided into four groups (n = 10): Control, OA, PEMF, and WBV.

Effects of Pulsed Electromagnetic Field Therapy on Pain, Stiffness, Physical Function, and Quality of Life in Patients With Osteoarthritis: A Systematic Review and Meta-Analysis of Randomized Placebo-Controlled Trials.

Objective: Pulsed electromagnetic field (PEMF) therapy is a potentially useful treatment for osteoarthritis (OA), but its effectiveness is still controversial. This study aimed to examine the effects of PEMF therapy and PEMF parameters on symptoms and quality of life (QOL) in patients with OA.

Methods: Cochrane Central Register of Controlled Trials, PubMed, CINAHL, EMBASE, PEDro, clinical trial registers, and reference lists were searched until April 2019.

Effectiveness of Elastic Taping in Patients With Knee Osteoarthritis: A Systematic Review and Meta-Analysis.

Objective: The aim of the study was to assess the effects of elastic taping on pain, physical function, range of motion, and muscle strength in patients with knee osteoarthritis.

Design: We searched the PubMed, the Cochrane Central Register of Controlled Trials, Web of Science, Physiotherapy Evidence Database, Scopus, EMBASE, OVID, CNKI, and WANFANG to identify relevant randomized controlled trials. The primary outcome measures were pain and physical function.

Effects of electromagnetic fields on osteoarthritis.

Osteoarthritis (OA), characterized by joint malfunction and chronic disability, is the most common form of arthritis. The pathogenesis of OA is unclear, yet studies have shown that it is due to an imbalance between the synthesis and decomposition of chondrocytes, cell matrices and subchondral bone, which leads to the degeneration of articular cartilage. Currently, there are many therapies that can be used to treat OA, including the use of pulsed electromagnetic fields (PEMFs).

Fast determination of two atractylenolides in Rhizoma Atractylodis Macrocephalae by Fourier transform near-infrared spectroscopy with partial least squares.

Rhizoma Atractylodis Macrocephalae (RAM) is a commonly used food and traditional Chinese medicine (TCM), which traditionally strengthens the spleen, benefits vital energy, eliminates dampness, and promotes hidroschesis. Its primary effective constituents are polysaccharides and volatile oil, whose main components are atractylenolide I and III. Fourier transform near-infrared spectroscopy (FT-NIR) is widely used in TCM research.
