    Abstract Chemical investigation on a Streptomyces sp. strain MS180069 isolated from a sediment sample collected from the South China Sea, yielded the new benzo[f]isoindole-dione alkaloid, bhimamycin J (1). The structure was determined by extensive spectroscopic analysis, including HRMS, 1D, 2D NMR, and X-ray diffraction techniques. A molecular docking study revealed 1 as a new molecular motif that binds with human angiotensin converting enzyme2 (ACE2), recently described as the cell surface receptor responsible for uptake of 2019-CoV-2. Using enzyme assays we confirm that 1 inhibits human ACE2 79.7 % at 25 μg/mL.

    Abstract: ... of double J ureteral stents via preexisting nondilated nephrostomy routes under fluoroscopic guidance ... respectively, all of which resolved spontaneously.: Conclusions: Percutaneous antegrade removal of double J ...

    Abstract Purpose: To evaluate the safety and clinical efficacy of an antegrade approach in the removal of double J ureteral stents via preexisting nondilated nephrostomy routes under fluoroscopic guidance.
    Materials and methods: Under fluoroscopic guidance and local anesthesia, antegrade removal of 39 ureteral stents in 27 patients was attempted by using a snare or basket. Indications for percutaneous stent removal included the presence of a preexisting nephrostomy route (n = 8), a surgical history resulting in an inaccessible retrograde route (n = 8), urethral stricture (n = 5), upward stent migration (n = 2), inability to obtain a lithotomy position (n = 1), fragmentation of the proximal stent (n = 1), and inability to find the ureteral orifice with a cystoscope (n = 2).
    Results: Thirty-seven of the 39 stents (95%) were successfully removed by using a snare or basket. Two stents (5.1%) could not be removed with a snare or basket because they were embedded against the renal calyx or pelvis. There were no major complications. Blood clot formation or laceration or tract leakage of the pelvicalyceal system occurred in six and two patients, respectively, all of which resolved spontaneously.
    Conclusions: Percutaneous antegrade removal of double J ureteral stents with a snare or basket via a nondilated nephrostomy route is effective without major complications in patients with an available nephrostomy route or an inaccessible retrograde option.

    Abstract Objective: To study the electrophysiological properties of parvalbumin (PV) neurons in the auditory cortex (AC) and its descending auditory projection area in the tail of the striatum (TS).
    Methods: The stimulation response of PV neuron step current was recorded in PV-Cre-Ai14 mice using in vitro patch clamp technique, and the release characteristics and waveform characteristics of PV neuron action potentials (APs) were analyzed using Clampfit and MATLAB software. The release characteristics of the APs included AP onset, rheobase, average firing rate, F/I slope and spike frequency adaptation (SFA); the waveform characteristics included peak and post potential characteristics.
    Results: The PV neurons of the TS and the AC had significantly different electrophysiological characteristics. In terms of peak potential characteristics, the PV neurons in the TS presented with smaller half peak width (
    Conclusion: The PV neurons in the TS and the AC of mice show significantly different electrophysiological characteristics in processing auditory information.

    Abstract Objective: To investigate the influence of positioning accuracy of the multi-leaf collimators (MLC) on the passing rate of the plan dose verification for volumetric modulation arc therapy (VMAT) of cervical cancer using an Elekta linear accelerator.
    Methods: The dose distributions were measured using Sun Nuclear's Mapcheck and Arccheck semiconductors matrix before and after MLC calibration in30 cervical cancer patients undergoing VMAT. Dosimetric comparisons were performed with 2D and 3D gamma passing rates of 3%, 3 mm and 2%, and 2 mm. The 3D gamma distribution was reconstructed with respect to the patient's anatomy using 3DVH software to evaluate the possible influence of MLC positioning accuracy.
    Results: Before and after MLC calibration, the gamma passing rates of Mapcheck were (88.80±1.81)% and (99.25 ± 0.53)% under 3% and 3 mm standard, respectively, with an average increase of 10.45%. The corresponding gamma passing rates of Arccheck were (87.61±1.98)% and (98.13±0.99)%, respectively, with an average increase of 10.52%. The gamma passing rates of 3DVH were (89.87±2.28)% and (98.3±1.15)%, respectively, with an average increase of 8.43%.
    Conclusion: The MLC positioning accuracy is one of the main factors influencing dosimetric accuracy of VMAT for cervical cancer. The application of Autocal software facilitates MLC calibration and improves the accuracy and safety of VMAT delivery for cervical cancer.
