Abstract
Utilizing energy transfer catalysis, this research employed the bifunctional reagents benzotriazole carboxylic acid oxime esters to simultaneously generate benzotriazole and imine radicals. The synthesis of two distinct C-N bonds in a single conversion is showcased through radical addition and radical-radical cross-coupling processes between benzotriazole carboxylic acid oxime ester and olefins. This process facilitates the intermolecular two-component unsymmetrical diamination reaction of olefins. Using this approach, more than 40 benzotriazole-containing molecules were successfully synthesized using styrene, indole, and benzofuran as acceptors, with yields ranging from moderate to excellent.

Abstract
BACKGROUND Perianal fistulising Crohn's disease (PFCD) and glandular anal fistula have many similarities on conventional magnetic resonance imaging. However, many patients with PFCD show concomitant active proctitis, but only few patients with glandular anal fistula have active proctitis.
AIM To explore the value of differential diagnosis of PFCD and glandular anal fistula by comparing the textural feature parameters of the rectum and anal canal in fat suppression T2-weighted imaging (FS-T2WI).
METHODS Patients with rectal water sac implantation were screened from the first part of this study (48 patients with PFCD and 22 patients with glandular anal fistula). Open-source software ITK-SNAP (Version 3.6.0, http://www.itksnap.org/) was used to delineate the region of interest (ROI) of the entire rectum and anal canal wall on every axial section, and then the ROIs were input in the Analysis Kit software (version V3.0.0.R, GE Healthcare) to calculate the textural feature parameters. Textural feature parameter differences of the rectum and anal canal wall between the PFCD group vs the glandular anal fistula group were analyzed using Mann-Whitney U test. The redundant textural parameters were screened by bivariate Spearman correlation analysis, and binary logistic regression analysis was used to establish the model of textural feature parameters. Finally, diagnostic accuracy was assessed by receiver operating characteristic-area under the curve (AUC) analysis.
RESULTS In all, 385 textural parameters were obtained, including 37 parameters with statistically significant differences between the PFCD and glandular anal fistula groups. Then, 16 texture feature parameters remained after bivariate Spearman correlation analysis, including one histogram parameter (Histogram energy); four grey level co-occurrence matrix (GLCM) parameters (GLCM energy_all direction_offset1_SD, GLCM entropy_all direction_ offset4_SD, GLCM entropy_all direction_offset7_SD, and Haralick correlation_all direction_ offset7_SD); four texture parameters (Correlation_all direction_offset1_SD, cluster prominence _angle 90_offset4, Inertia_all direction_offset7_SD, and cluster shade_angle 45_offset7); five grey level run-length matrix parameters (grey level nonuniformity_angle 90_offset1, grey level nonuniformity_all direction_offset4_SD, long run high grey level emphasis_all direction_offset1_SD, long run emphasis_all direction_ offset4_ SD, and long run high grey level emphasis_all direction_offset4_SD); and two form factor parameters (surface area and maximum 3D diameter). The AUC, sensitivity, and specificity of the model of textural feature parameters were 0.917, 85.42%, and 86.36%, respectively.
CONCLUSION The model of textural feature parameters showed good diagnostic performance for PFCD. The texture feature parameters of the rectum and anal canal in FS-T2WI are helpful to distinguish PFCD from glandular anal fistula.

Abstract
The consumer buying process refers to the procedures taken by a buyer when making a purchase. There are patterns that customers follow before they make purchases that can be described as consumer behavior. When making decisions, businesses and engineers turn to big data for the valuable insights it contains. Edge computing, although presenting processing issues, has aided in the evolution of big data by offering computational, networking, and storage capability. The process consists of identifying needs and wants, conducting research, evaluating options, and making a purchase, followed by evaluating the purchase. This is a considered major problem in the prediction history. To overcome these issues, here comes a framework of predicting customer purchasing using big data analytics (PCP-BDA) to determine the purpose of every customer becoming aware of the need or desire for a product and ends with the purchase transaction.

Abstract
BACKGROUND Magnetic resonance imaging (MRI) is currently the standard investigation for suspected perianal diseases. Carcinoma arising from anal fistula is very rare, and early diagnosis is often difficult.
AIM To describe and summarize the MRI findings of carcinoma arising from anal fistula.
METHODS In this retrospective study, records of ten patients diagnosed with carcinoma arising from anal fistula and confirmed by surgery (n = 7) or biopsy (n = 3) between June 2006 and August 2018 were analyzed. All patients underwent preoperative pelvic MRI. Morphologic features, signal characteristics, fistula between the mass and the anus, contrast enhancement of mass, signal and enhancement of peritumoral areas, and regional lymphadenopathy were assessed.
RESULTS All ten tumors were solitary (8 mucinous adenocarcinomas and 2 adenocarcinomas). The maximum diameter of the tumors ranged from 3.4 cm to 12.4 cm (median: 4.15 cm; mean: 5.68 cm). Eight patients had a fistula between the mass and the anus. Contrast enhancement of the peritumoral areas was noted in three (3/5) patients. Perirectal or inguinal lymphadenopathy was noted in seven patients. Most lesions of mucinous adenocarcinoma were multiloculated and cauliflower-like, with a thin capsule and focally unclear boundary. They were markedly hyperintense on fat-suppressed T2WI, slightly hyperintense with focal hyperintensity on diffusion-weighted imaging (DWI), and hyperintense with focal hypointensity on apparent diffusion coefficient (ADC) map, with progressive mesh-like contrast enhancement. Adenocarcinomas had an infiltrative margin without a capsule and appeared heterogeneously hyperintense or slightly hyperintense on fat-suppressed T2WI, hyperintense on DWI, and hypointense on ADC map, with persistent heterogeneous enhancement.
CONCLUSION Our study highlighted several characteristic and potentially helpful MRI findings to diagnose carcinomas arising from anal fistula.

Abstract
Objective: To explore the value of contrast-enhanced CT combined with texture analysis in differentiating pancreatic cancer from mass-forming pancreatitis in pancreatic head. Methods: A retrospective study collected 21 patients with pancreatic head mass-forming pancreatitis confirmed by surgery or biopsy and 47 patients with pancreatic ductal adenocarcinoma confirmed by surgery. The patients visited the Affiliated Hospital of Nanjing University of Chinese Medicine and the First Affiliated Hospital of Wannan Medical College between January 2014 and December 2017. Gender, age and CT findings were collected. The parenchymal phase was selected for texture analysis. The minimum absolute shrinkage and selection operator (LASSO) method was applied for dimensionality reduction.Two independent sample t-tests or Mann-Whitney U test were used for continuous variables based on the Shapiro-Wilks normality test results. Categorical variables were tested by Chi-square or Fisher test. By multivariable regression analysis, CT findings, CT texture analysis, CT findings combined with texture analysis prediction models were established. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic performance of individual indicators and each prediction model. The Delong test was used to compare the area under the curve (AUC) of each model. Results: The CT findings prediction model consisted of CT value of lesion on pancreatic parenchymal phase and pancreatic duct penetrating sign. The texture analysis prediction model consists of root mean square and low grey level run emphasis_angle135. The AUC of them were not statistically different (Z=0.150,P>0.05). The combined predictive model had the better diagnostic performance (AUC 0.944, sensitivity 83.0%, specificity 95.2%, +LR 17.43, -LR 0.18) than CT sign prediction model (Z=2.008, P<0.05) and texture analysis prediction model(Z=2.236, P<0.05) were significantly different. Conclusions: The CT findings model and the texture analysis model have equivalent diagnostic performance in the differentiation of mass-forming pancreatitis and pancreatic cancer. The enhanced CT combined with texture analysis model has the best diagnostic efficiency and can further improve the diagnostic ability.

Abstract
Metagenome, a term first dubbed by Handelsman in 1998 as "the genomes of the total microbiota found in nature", refers to sequence data directly sampled from the environment (which may be any habitat in which microbes live, such as the guts of humans and animals, milk, soil, lakes, glaciers, and oceans). Metagenomic technologies originated from environmental microbiology studies and their wide application has been greatly facilitated by next-generation high throughput sequencing technologies. Like genomics studies, the bottle neck of metagenomic research is how to effectively and efficiently analyze the gigantic amount of metagenomic sequence data using the bioinformatics pipelines to obtain meaningful biological insights. In this article, we briefly review the state-of-the-art bioinformatics software tools in metagenomic research. Due to the differences between the metagenomic data obtained from whole genome sequencing (i.e., shotgun metagenomics) and amplicon sequencing (i.e., 16S-rRNA and gene-targeted metagenomics) methods, there are significant differences between the corresponding bioinformatics tools for these data; accordingly, we review the computational pipelines separately for these two types of data.

Abstract
Colonic motility disorders are common conditions. However, our understanding of normal and pathological motor functions of the colon remains limited, mainly due to the technical difficulties in accessing this organ for study. To investigate colonic motility under normal physiological conditions, we have developed a novel monitoring system based on a telemetry technique. The system is capable of prolonged and noninvasive measurement of intraluminal pressure changes and transit time of intra-colonic contents. To test the in vivo performance of the monitoring system, 15 healthy volunteers and 15 patients with functional constipation (FC) participated in this study. A single-use telemetry capsule embedded with sensors was ingested by the subjects. The capsule is capable of transmitting colonic pressure and temperature wirelessly. The time of the telemetry capsule entering the segmental colon was detected by ultrasonic detection of the batteries in capsule. Pressure recordings confirmed in general a circadian behavior of colonic motility, as well as its response to waking and meals. In the FC patients, the contractile response to morning awakening and meal ingestion was significantly lower compared to the controls. The transit time measured using this method agreed with the time calculated from radiopaque markers (r = 0.89, p < 0.05). The clinical study proved both the reliability and the noninvasiveness of the system. This capsule-style manometric system may represent a useful tool for the study of physiology and pathology of colonic motor disorders.
