    Abstract Introduction: In recent decades, widespread multi-drug resistant (MDR) bacteria have become a serious problem in healthcare facilities.
    Methods: To systematically summarize and investigate the prevalence and genomic features of clinical MDR
    Results: All of these isolates were generally resistant to the common β-lactamase antibiotics. Resistance to cefoperazone-sulbactam varies greatly between different clones. The proportion of CC208 isolates resistant and mediated to cefoperazone-sulbactam is as high as 84.6%. There were no isolates resistant to tigecycline and colistin. The presence of

    Abstract ABT737 is used as a specific BCL2 inhibitor, which can treat papillary thyroid carcinoma (PTC). However, the effect of ABT737 on PTC cell apoptosis is limited. Moreover, BCL2 inhibition causes the activation of Beclin1-dependent autophagy. Our study aimed to explore the effects of autophagy and Beclin1 on ABT737 efficacy in PTC. The experimental data showed that ABT737 synchronously enhanced autophagic activity and apoptosis level in PTC cells. ABT737 also promoted the dissociation of BCL2-Beclin1 and BCL2-Bax complexes. Autophagy inhibitors, Bafilomycin A1 and 3-MA, enhanced the inhibitory effect of ABT737 on the survival and function in PTC cells. Consistently, autophagy inhibition with Beclin1 pharmacological inhibitor (spautin-1) also enhanced the efficacy of ABT737. Additionally, ABT737 at low-dose promoted LC3 conversion in PTC cells, and did not affect PTC cell apoptosis and survival. However, The efficacy of low-dose of ABT737 in PTC cell apoptosis and survival was displayed with the addition of Bafilomycin A1, 3-MA or spautin-1. In conclusion, the limited role of ABT737 in PTC cell apoptosis is attributed to its promoting effect on Beclin1-dependent autophagy. Therefore, autophagy inhibition based on Beclin1 downregulation can enhance the sensitivity of PTC cells to ABT737-induced death.

    Abstract In this work, the ultrafast intramolecular rotation behavior of 1,1,2,3,4,5-hexaphenylsilole has been investigated in several solutions with different viscosities using femtosecond transient absorption spectroscopy combined with density functional theory and time-dependent density functional theory calculations. It is demonstrated that the nonradiative process, which competes with radiative decay, involves two main stages, namely the restricted intramolecular rotation and internal conversion processes. The intramolecular rotation depends on viscosity and presents a significant restriction. The restricted rotational rate is determined to be dozens of picoseconds. The following nonradiative process is strongly dominated by intramolecular rotation. The nonradiative decay rate will decrease with the increase in viscosity, leading to a rise in the radiative probability and photoluminous yield. These results have borne out the mechanism of ultrafast restricted intramolecular rotation of aggregation induced emission and provided a detailed photophysical picture of nonradiative processes.

    Abstract Feline calicivirus (FCV) is a highly contagious pathogen seriously affecting the upper respiratory tract and producing oral diseases in the feline. Despite widespread vaccination, the prevalence of FCV remains high. In this study, the FCV qingdao (qd)/2019/china was isolated from a domestic feline oropharyngeal swab collected from Qingdao, China. The virus was purified using the plaque assay and identified using the Polymerase chain reaction and indirect immunofluorescence assay methods, the capsid amino acid,

    Abstract Papillary thyroid carcinoma (PTC) limits effective biomarkers for predicting prognosis and targeted therapy. Phosphatase and actin regulator 1 (PHACTR1) is a mobility-promoting molecule due to its regulation on F-actin formation, which is valuable for the investigation of PTC. Our study aimed to investigate the relationship between PHACTR1 and PTC carcinogenesis, especially mobility. Our results displayed that PHACTR1 expression was elevated in metastatic or larger PTC tissues. In addition, PTC cells K1 with more obvious mobility had higher PHACTR1 expression whereas weakly mobile cells TPC-1 was contrary. Moreover, PHACTR1 silencing inhibited the invasion, migration and tumorigenicity of K1 cells, while PHACTR1 overexpression promoted the invasion, migration and tumorigenicity in TPC-1 cells. Furthermore, PHACTR1 overexpression increased the fluorescent intensity of F-actin in TPC-1 cells. Importantly, the enhanced invasion and migration in TPC-1 cells caused by PHACTR1 overexpression were significantly reversed by the disruption of F-actin assembly with swinholide A. In conclusion, PHACTR1 can promote the mobility of PTC cells, which results in the carcinogenesis of PTC. PHACTR1-regulated F-actin formation determines the mobility of PTC cells. Therefore, PHACTR1 can function as a potential biomarker for predicting prognosis and targeting therapy in PTC.

    Abstract The detection of lysine acetyltransferases is crucial for diagnosing and treating lung cancer, highlighting the necessity for highly efficient detection methods. We developed a portable, highly accurate, and sensitive technique using fast-scan cyclic voltammetry (FSCV) to determine the activity of the lysine acetyltransferase TIP60, employing a novel miniature electrochemical sensor. This approach involves a compact electrochemical cell, merely 3 mm in diameter, that holds solutions up to 50 μL, equipped with a conductive indium tin oxide working electrode. Uniquely, this system operates on a two-electrode model compatible with the FSCV, obviating the traditional requirement for a reference electrode. The system detects TIP60 activity through the continuous generation of CoA molecules that engage in reactions with Cu(II), thereby significantly improving the accuracy of the acetylation analysis. Remarkably, the detection limit achieved for TIP60 is notably low at 3.3 pg/mL (
