Background: MicroRNAs play important roles in regulation of the cardiovascular system. The purpose of this study was to investigate microRNA-320 (miR-320) expression in myocardial ischemia-reperfusion (I/R) injury and the roles of miR-320 in cardiomyocyte apoptosis by targeting AKIP1 (A kinase interacting protein 1). Methods: The level of miR-320 was detected using quantitative real-time polymerase...
Five types of kitchen waste (KW) from China – including hop pot (HP), fast food (FF), Hebei cuisine (HC), university canteen (UC), and other mixed KW (Other) – were investigated as feedstock for potential biogas and methane production. The biodegradability of KW was measured using batch anaerobic digestion (AD) tests and feedstock at an inoculum ratio (F/I) of 0.5. Gompertz and Cone models were used...
For pretreating waste-activated sludge, the combined alkali and microwave pretreatment is a promising hybrid method. To make this pretreatment more economical, moderate conditions were applied for central composite design of the experiments. A quadratic model was established to describe the influence of NaOH dosage and microwave processing time on methane production. The optimal condition was 0.12...
Port shoreline resources are the basis of port and shipping development, and its assessment method has become one of the hot issues in port research. On the basis of constructing a reasonable index evaluation system, this paper constructs the fuzzy evaluation matrix based on the triangular fuzzy analytic hierarchy process and constructs the fuzzy evaluation matrix by using the fuzzy comprehensive...
Port as one of the key hubs of international logistics, which has become the main part and the base of global logistics management. The port enterprises, plays an important role in the global supply chain. However, due to the lack of understanding in port supply chain management, coordination between the port enterprises, the integration of business process is not perfect, the lack of information...
Marine transportation is the most important transport mode of in the international trade, but the maritime supply chain is facing with many risks. At present, most of the researches on the risk of the maritime supply chain focus on the risk identification and risk management, and barely carry on the quantitative analysis of the logical structure of each influencing factor. This paper uses the interpretative...
A two-phase pressurized biofilm (TPPB) system, including a continuously stirred tank reactor (CSTR) and a pressurized biofilm anaerobic reactor (PBAR), was used to produce high calorific biogas without additional upgrading equipment. The influence of organic loading rate (OLR) on biogas and methane production performance was investigated. Three different OLR levels (4, 5, and 6 g-COD/L/d) were applied...
The main aim of this study was to screen and identify cadmium-resistant fungus and to characterize its cadmium adsorption. A cadmium-resistant strain (CN35) was isolated from cadmium-polluted paddy soil. Based on morphlogical characteristics, internal transcribed spacers region and β-tubulin gene sequence phylogenesis analysis, the strain was preliminarily identified to be Penicillium sp. This strain...
A common approach to increasing biogas production is enhancing the hydrolysis of wheat straw by removing the lignin-using chemicals. However, partial organic matter will also dissolve into chemical solutions during pretreatment, which leads to the loss of organic matter for the anaerobic digestion process. The enzymatic hydrolysis of wheat straw and loss of total organic carbon increased with NaOH...
A semi-field test was conducted to assess the risk of exposure to fufenozide in a ditch and pond adjacent to an agricultural area. To support the investigation, a fast, highly selective, and sensitive method was developed to determine the residue of fufenozide in water, sediment, and soil through high performance liquid chromatography- tandem mass spectrometry. The recoveries were in the acceptable...
Hypoxic-Ischemic Encephalopathy (HIE) is one of the most recognized causes of neurological deficits in children. Cerebral blood flow (CBF) reductions, as seen with HIE, resulting in neuronal injury have not been evaluated in real-time. Photoacoustic Tomography (PAT) is a form of optical imaging which can detect cerebral hemodynamic alterations in a non- invasive, non-ionizing fashion via changes in...
