and lower zone pulmonary opacifications as well as intra-abdominal inflammation. Elucidating the distinguishing radiographic features of MIS-C may help refine the case definition and expedite diagnosis and treatment.
Key chest radiographic features of MIS-C versus those of COVID-19 were pleural effusions and lower zone pulmonary opacifications as well as intra-abdominal inflammation. Elucidating the distinguishing radiographic features of MIS-C may help refine the case definition and expedite diagnosis and treatment.
To establish a reproducible porcine model of ascending aortic aneurysm (AsAA).
We created an AsAA in twelve domestic pigs using a cover-then-cut method, stitching a glutaraldehyde tanned bovine pericardial patch onto the anterolateral aortic wall, then cutting off aortic wall tissue within the patch, and closing the incision in the patch.
The AsAA creation was completed successfully in 11 out of the 12 pigs (91.7%). The mean maximal diameter of the ascending aorta increased significantly by 1.77 times, immediately after the operation (p < 0.05). Significantly continuous expansion of the aneurysm was observed during the follow up period, to 48.9 ± 1.80mm at 3months and 50.3 ± 2.25mm at 6months (p < 0.05).
This porcine model of AsAA, created using a repeatable cover-then-cut method, represents a reproducible platform for studying and training, which could contribute to the development of new feasible endovascular treatments of AsAAs.

The purpose of this study was to assess whether the anesthetic type is associated with the prognosis of pathological stage I non-small cell lung cancer (NSCLC).
Clinicopathological data from 431 consecutive patients who underwent lobectomy for NSCLC between 2010 and 2016 were collected. Epalrestat Patients were classified into groups according to the type of anesthesia propofol-based total intravenous anesthesia (TIVA) or inhalation anesthesia (INHA). We investigated the prognostic differences between these two groups.
A total of 72 patients in the TIVA group and 158 patients in the INHA group were eligible for the analysis. Recurrence was observed in 4 (5.6%) patients in the TIVA group and 19 (12.0%) patients in the INHA group (P = 0.159), and all-cause death occurred in 4 (5.6%) patients in the TIVA group and 24 (15.2%) patients in the INHA group (P = 0.049). The 5-year recurrence-free survival (RFS) and overall survival rates of the TIVA/INHA groups were 91.7%/77.4% and 94.4%/83.5%, respectively. TIVA was associated with a significantly better prognosis. A multivariable analysis of factors associated with RFS revealed that the type of anesthesia as a significant prognostic factor (P = 0.047).
Propofol-based TIVA was associated with a better prognosis in comparison to INHA in patients with surgically resected pathological stage I NSCLC.

The integration of α-Fe2O3.PdNPs with a polyphenol oxidase as a biorecognition element yields a novel biosensing platform. Under visible light irradiation, the photoactive biocomposite can generate a stable photocurrent, which was found to be directly dependent upon the concentration of rutin. Under the optimal experimental conditions, the cathodic photocurrent, measured at 0.33 V vs. Ag/AgCl, from the square-wave voltammograms presented a linear dependence on the rutin concentration within the range of 0.008-30.0 × 10-8 mol L-1 (sensitivity 1.7 μA·(× 10-8 M-1)·cm-2), with an experimental detection limit (S/N = 3) of 8.4 × 10-11 mol L-1. The proposed biosensor device presented good selectivity towards rutin in the presence of various organic compounds and inorganic ions, demonstrating the potential application of this biosensing platform in complex matrices. This bioanalytical device also exhibited excellent operational and analytical properties, such as intra-day (standard deviation, SD = 0.21%) and inter-day (SD = 1.30%) repeatability, and long storage stability (SD = 2.80% over 30 days).Graphical abstract.An early detection of Mycobacterium tuberculosis is very important to reduce the number of fatal cases and allow for fast recovery. However, the interpretation of the result from smear microscopy requires skilled personnel due to the propensity of the method to produce false-negative results. In this work, a portable, rapid, and simple sandwich-type immunosensor reader has been developed that is able to detect the presence of M. tuberculosis in sputum samples. By using sandwich-type immunosensor, an anti-CFP10-ESAT6 antibody was immobilized onto the graphene/polyaniline (GP/PANI)-modified gold screen-printed electrode. After incubation with the target CFP10-ESAT6 antigen, the iron/gold magnetic nanoparticles (Fe3O4/Au MNPs) conjugated with anti-CFP10-ESAT6 antibody were used to complete the sandwich format. Differential pulse voltammetry (DPV) technique was used to detect the CFP10-ESAT6 antigen at the potential range of 0.0-1.0 V. The detection time is less than 2 h. Under optimal condition, CFP10-ESAT6 antigen was detected in a linear range from 10 to 500 ng mL-1 with a limit of detection at 1.5 ng mL-1. The method developed from this process was then integrated into a portable reader. The performance of the sensor was investigated and compared with the standard methods (culture and smear microscopy). It provides a good correlation (100% sensitivity and 91.7% specificity) with both methods of detection for M. tuberculosis in sputum samples henceforth, demonstrating the potential of the device as a more practical screening tool.Graphical abstract.
