Rapid scale-up and intensification of the livestock and poultry farming industry generates massive amount of wastewater that greatly contributes to the environmental pollution in the vicinity. The microbial fuel cell (MFC) is an electrochemical technology that enables removal of organic pollutants in the wastewater and power generation concomitantly with the aid of microorganisms. This technology has a great potential in treating high-concentration wastewater released from the livestock and poultry farming. The present study described the categories of MFCs and current research status of its application in wastewater treatment from two aspects: 1) removal of organic pollutants (e.g., chemical oxygen demand, ammonia nitrogen, total phosphorus, and antibiotics) and 2) electricity production performance. The potential of using multiple MFC technologies together in wastewater treatment was also elaborated. This study revealed the existing problems associated with current MFC technologies and provided directions for future research, including equipment scale-up, development of novel coupling MFC technologies, interpretation of interactions among controllable parameters, and in-depth exploitation of mechanisms underlying pollutant removal and electron transfer.

Objectively evaluating the impact of the Belt and Road Initiative on China ’s inbound tourism and systematically exploring its mechanisms are of guiding significance for promoting the development of China ’s inbound tourism. Using the panel data of 104 countries from 2010 to 2019, this study took the implementation of the Belt and Road Initiative as a quasi-natural experiment to construct a difference-in-differences model. Combining perspectives of economic connections and cultural communication, this study also used the methods of mediating effect and text mining and analysis to testify the mechanisms and applied the moderating effect to explore the possible interactions within the mechanisms. The results showed that: ① The Belt and Road Initiative significantly increased the number of tourists to China from the countries along the Belt and Road by about 15.03% to 30.10% annually, thus promoting the development of China’s inbound tourism. ② International trade played a mediating role in this relationship. Compared with the import trade (39.17%), the export trade (47.05%) had a greater impact on this relationship. ③ Cultural identity played a mediating role in this relationship. The impact of the Belt and Road Initiative on cultural identity presented a mode of ‘three cores, six tones, and numerous elements,’ with the hot spots focusing on Chinese learning, education, art, traditional Chinese medicine, the motion picture industry, and the publishing industry. ④ The mechanisms of ‘traveling for business’ and ‘traveling for culture’ coexisted and interacted positively. Export trade had a greater impact on the interaction between the two than import trade. [ABSTRACT FROM AUTHOR]

Objective To investigate the MRI feature of continuous enhancement from index lesion to nipple-areola complex (NAC) for preoperative prediction of occult NAC involvement in patients with breast cancer. Methods Between January 2017 and September 2018. 242 patients with breast cancer were enrolled in this prospective study. The patients underwent breast MRI before radical mastectomy. They were divided into a NAC-positive and NAC-negative groups based on the pathologic results regarding NAC involvement. Preoperative MRI features such as lesion type, location, tumor size, enhancement pattern, multicentricity, tumor—to—NAC continuous enhancement, tumor—to—NAC distance and nipple retraction were compared between the two groups using Pearson X2 test. The diagnostic performance of tumor-to-NAC continuous enhancement for occult NAC involvement was evaluated. Results Of the 242 breast cancer patients, 47 were NAC-positive and 195 were NAC-negative. The tumor-to-NAC continuous enhancement was significantly different between NAC-positive and NAC-negative groups (P<0.001). It was present in 34 (72.3%) NAC-positive patients and in 11 (5.6%) NAC-negative patients. The other 7 MRI features were not significantly different between the two groups (P=0.110-0.696). Tumor-to-NAC continuous enhancement was 72.3% sensitive, 94.4% specific, 90.1% accurate with 75.6% positive predictive value and 93.4% negative predictive value for the diagnosis of occult NAC involvement. Conclusion Tumor-to-NAC continuous enhancement is an effective MRI feature for the preoperative prediction of occult NAC involvement in breast cancer. [ABSTRACT FROM AUTHOR]
