    Abstract Background. The role and expression level change in circ_TNPO1 (hsa_circ_0072951) in atherosclerosis (AS) and VSMC dysfunction remain unknown. In this study, we try to explore the effects of circ_TNPO1 on oxidized low-density lipoprotein (ox-LDL)-induced human vascular smooth muscle cell (VSMC) excessive proliferation and migration, and the potential molecular mechanism. Methods. Quantitative real-time polymerase chain reaction (RT-qPCR) and western blot experiment were used to detect the serum samples from AS patients and healthy controls. CCK-8, Transwell, and the dual-luciferase reporter gene assay were used to detect the cell biology. Results. In human AS serum and ox-LDL-induced VSMCs, circ_TNPO1 was increased, whereas miR-181b was decreased. Silencing circ_TNPO1 inhibited proliferation and migration activity and reduced protein expression of PCNA, Ki-67, MMP2, and E-cadherin and promoted N-cadherin protein expression in ox-LDL induced VSMCs. Remarkably, miR-181b knockdown or Notch1 overexpression could efficiently offset the proliferation and migration inhibiting effect of circ_TNPO1 knockdown in ox-LDL-induced VSMCs. Furthermore, a molecular mechanism study pointed out that circ_TNPO1 and Notch1 are direct-acting targets of miR-181b. Conclusions. In conclusion, our study indicated that circ_TNPO1 promotes the proliferation and migration progression of VSMCs in atherosclerosis through the miR-181b/Notch1 axis.

    Abstract Abstract Thermodynamics is built with the concept of equilibrium states. However, it is less clear how equilibrium thermodynamics emerges through the dynamics that follows the principle of quantum mechanics. In this paper, we develop a theory of quantum thermodynamics that is applicable for arbitrary small systems, even for single particle systems coupled with a reservoir. We generalize the concept of temperature beyond equilibrium that depends on the detailed dynamics of quantum states. We apply the theory to a cavity system and a two-level system interacting with a reservoir, respectively. The results unravels (1) the emergence of thermodynamics naturally from the exact quantum dynamics in the weak system-reservoir coupling regime without introducing the hypothesis of equilibrium between the system and the reservoir from the beginning; (2) the emergence of thermodynamics in the intermediate system-reservoir coupling regime where the Born-Markovian approximation is broken down; (3) the breakdown of thermodynamics due to the long-time non-Markovian memory effect arisen from the occurrence of localized bound states; (4) the existence of dynamical quantum phase transition characterized by inflationary dynamics associated with negative dynamical temperature. The corresponding dynamical criticality provides a border separating classical and quantum worlds. The inflationary dynamics may also relate to the origin of big bang and universe inflation. And the third law of thermodynamics, allocated in the deep quantum realm, is naturally proved.

    Abstract BackgroundThe development of antimicrobial resistance in the opportunistic pathogen Escherichia coli has become a global public health concern. Due to daily close contact, dogs kept as pets share the same E. coli with their owners. Therefore, the detection of antimicrobial resistance in canine E. coli is important, as the results could provide guidance for the future use of antibiotics. This study aimed to detect the prevalence of antibiotic-resistance of canine origin E. coli in Shaanxi province and to explore the inhibition effect of magnolol combined with cefquinome on MDR E. coli, so as to provide evidence for the use of antibiotics.MethodsCanine fecal samples were collected from animal hospitals. The E. coli isolates were separated and purified using various indicator media and polymerase chain reaction (PCR). Drug-resistance genes [aacC2, ant(3')-I, aph(3')-II, aac(6')-Ib-cr, aac(3')-IIe, blaKPC, blaIMP−4, blaOXA, blaCMY, blaTEM−1, blaSHV, blaCTX−M−1, blaCTX−M−9, Qnra, Qnrb, Qnrs, TetA, TetB, TetM, Ermb] were also detected by PCR. The minimum inhibitory concentration (MIC) was determined for 10 antibiotics using the broth-microdilution method. Synergistic activity of magnolol and cefquinome against multidrug-resistant (MDR) E. coli strains was investigated using checkerboard assays, time-kill curves, and drug-resistance curves.ResultsA total of 101 E. coli strains were isolated from 158 fecal samples collected from animal hospitals. MIC determinations showed that 75.25% (76/101) of the E. coli strains were MDR. A total of 22 drug-resistance genes were detected among the 101 strains. The blaTEM−1gene exhibited the highest detection rate (89.77%). The TetA and Sul gene also exhibited high detection rate (66.34 and 53.47%, respectively). Carbapenem-resistant E. coli strains were found in Shangluo and Yan'an. Additionally, in MDR E. coli initially resistant to cefquinome, magnolol increased the susceptibility to cefquinome, with an FICI (Fractional Inhibitory Concentration Index) between 0.125 and 0.5, ...

    Abstract We investigate the dynamics of charge-state coherence in a degenerate double-dot Aharonov–Bohm interferometer with finite inter-dot Coulomb interactions. The quantum coherence of the charge states is found to be sensitive to the transport setup configurations, involving both the single-electron impurity channels and the Coulomb-assisted ones. We numerically demonstrate the emergence of a complete coherence between the two charge states, with the relative phase being continuously controllable through the magnetic flux. Interestingly, a fully coherent charge qubit arises at the double-dots electron pair tunneling resonance condition, where the chemical potential of one electrode is tuned at the center between a single-electron impurity channel and the related Coulomb-assisted channel. This pure quantum state of charge qubit could be experimentally realized at the current–voltage characteristic turnover position, where differential conductance sign changes. We further elaborate the underlying mechanism for both the real-time and the stationary charge-states coherence in the double-dot systems of study.

    Abstract Background: We aimed to investigate the feasibility and safety of mitral valve replacement using a totally thoracoscopic approach in comparison with traditional median sternotomy.
    Methods: Between January 2016 and December 2017, 94 consecutive patients who underwent mitral valve replacement were divided into two groups: A thoracoscopic group (43 cases) and a traditional group (51 cases). For the thoracoscopic group, all patients underwent total thoracoscopic procedures with femoral arterial and venous cannulation to cardiopulmonary bypass, transthoracic aortic cross-clamp, and antegrade cardioplegia. Three intercostal ports in the right chest were used for access in the thoracoscopic group. The operation was performed completely under two-dimensional video. For the traditional group, all operations were done with traditional median sternotomy.
    Results: All the operations were successfully performed. The thoracoscopic group had longer aortic cross-clamping and cardiopulmonary bypass times compared with the traditional group (62.30 ± 8.17 minutes versus 44.90 ± 12.00 minutes, P < .001; 92.33 ± 12.03 minutes versus 74.22 ± 14.72 minutes, P < .001). The two groups did not show statistically significant differences with respect to operative times (184.26 ± 32.49 minutes versus 181.47 ± 23.31 minutes, P = .631). In addition, the postoperative mechanical ventilation, ICU stay, and postoperative hospital stay times and postoperative drainage were 10.14 ± 2.21 hours and 11.35 ± 2.58 hours (P = .016), 21.40 ± 3.15 hours and 29.12 ± 6.59 hours (P < .001), 8.70 ± 2.52 days and 10.04 ± 3.11 days (P = .023), and 325.71 ± 97.11 mL and 396.57 ± 121.50 mL (P < .001), respectively. Major postoperative complications occurred in three (6.98%, P = .873) cases of the thoracoscopic group. Four (7.84%) cases of the traditional group had postoperative complications.
    Conclusions: Despite the disadvantages such as long cross-clamp and cardiopulmonary bypass times, totally thoracoscopic mitral valve replacement is feasible and safe. More importantly, one of the principal advantages with three intercostal ports over standard sternotomy is avoiding retrosternal adhesion, thus lowering the risk of needing to redo a cardiac procedure in the future.

    Abstract To enlarge the chemical diversity of Eurotium sp. SCSIO F452, a talented marine-derived fungus, we further investigated its chemical constituents from a large-scale fermentation with modified culture. Four pairs of new salicylaldehyde derivative enantiomers, euroticins F-I ( 1 – 4 ), as well as a known one eurotirumin ( 5 ) were isolated and characterized. Compound 1 features an unprecedented constructed 6/6/6/5 tetracyclic structures, while 2 and 3 represent two new types of 6/6/5 scaffolds. Their structures were established by comprehensive spectroscopic analyses, X-ray diffraction, 13 C NMR, and electronic circular dichroism calculations. Selected compounds showed significant inhibitory activity against α-glucosidase and moderate cytotoxic activities against SF-268, MCF-7, HepG2, and A549 cell lines.

    Abstract The development of drug-resistance in the opportunistic pathogen Escherichia coli has become a global public health concern. Due to the share of similar flora between pets and their owners, the detection of pet-origin antibiotic-resistant E. coli is necessary. This study aimed to detect the prevalence of feline-origin ESBL E. coli in China and to explore the resistance elimination effect of garlic oil to cefquinome on ESBL E. coli . Cat fecal samples were collected from animal hospitals. The E. coli isolates were separated and purified by indicator media and polymerase chain reaction (PCR). ESBL genes were detected by PCR and Sanger sequencing. The MICs were determined. The synergistic effect of garlic oil and cefquinome against ESBL E. coli was investigated by checkerboard assays, time-kill and growth curves, drug-resistance curves, PI and NPN staining, and a scanning electronic microscope. A total of 80 E. coli strains were isolated from 101 fecal samples. The rate of ESBL E. coli was 52.5% (42/80). The prevailing ESBL genotypes in China were CTX-M-1 , CTX-M-14 , and TEM-116 . In ESBL E. coli , garlic oil increased the susceptibility to cefquinome with FICIs from 0.2 to 0.7 and enhanced the killing effect of cefquinome with membrane destruction. Resistance to cefquinome decreased with treatment of garlic oil after 15 generations. Our study indicates that ESBL E. coli has been detected in cats kept as pets. The sensitivity of ESBL E. coli to cefquinome was enhanced by garlic oil, indicating that garlic oil may be a potential antibiotic enhancer.
