The relationship between the personal characteristics of senior management team members and the sustainable development of the enterprise has received much attention. This study used data on A-share listed companies in China from 2009 to 2022 to examine the effect of female executives on enterprise environmental, social, and governance (ESG) performance and tested the moderating role of ownership concentration and media exposure. Empirical testing was conducted on 20,188 annual observation samples using regression analysis. The empirical results demonstrate that female executives significantly improve corporate ESG performance, especially social responsibility performance. The study also revealed that ownership concentration plays an internal moderating role on the connection between female executives and corporate ESG performance, while media exposure plays an external moderating role. The conclusions remain the same after several robustness tests, including a lag test, substitution variable estimation, and propensity score matching. An economic consequence check and heterogeneity test were also conducted. This study's findings enrich the research on ESG influencing factors and offers empirical support for the value of female participation in corporate governance. [ABSTRACT FROM AUTHOR]

Having a large number of electric vehicles (EVs) on the road will lead to vehicle congestion, long waiting times at charging stations (CSs), and even the inability to find an available charging position. Main technical challenges in mobile EVs charging may include charging information exchanges between EVs and CSs, EV traveling route and CS selection, and EV charging planning. To solve the above problems, this study provides an optimization solution for entire-trip charging and navigation of EVs, which balances charging resources, protects the travel time of EV drivers, and prioritizes renewable energy. The communication scheme of an EV charging network is designed, including real-time communication between the CSs, EV drivers, road condition monitoring center, power grid company, and the charging control center distributed in every parking lot. CSs in each road segment sort vehicles arriving at stations, allocate charging time slots, provide charging start times, and adjust those times for EVs with reservations that have not yet arrived. EV drivers can plan vehicle charging on their smart devices. The optimization of electric navigation can reduce the travel time or cost for drivers, ensure safe electricity usage, calculate vehicle routes, select CSs, and provide charging time intervals. The effectiveness of the method is verified on a regional road network in China, and the results show that it can balance the charging resource distribution of a CS, guarantee EV state of charge level, greatly reduce travel cost or travel time, provide precise waiting time, and prioritize renewable energy. • High-speed communication enables an electric vehicle to obtain information in time. • High-speed communication provides real-time changes in a charging station. • Entire-trip navigation computation is performed on each driver' terminal device. • Each charging station sorts vehicles according to arrival time at the station. • The optimization of a driver's navigation can reduce travel time or cost.

Just like in sedimentary stratigraphy, the volcanostratigraphic boundary is an important factor for constructing volcanostratigraphic framework. The fundamental factor of volcanostratigraphic boundaries is to classify the types and define their characteristics. Based on field investigation and cross-wells section analysis of Mesozoic volcanostratigraphy in NE China, 5 types of volcanostratigraphic boundaries have been recognized, namely eruptive conformity boundary (ECB), ernptive unconformity boundary (EUB), eruptive interval unconformity boundary (EIUB), tectonic unconformity boundary (TUB) and intrusive contacts boundary (ICB). Except ICB, the unconformity boundaries can be divided into angular unconformity and paraconformity. The time spans and signs of these boundaries are analyzed by using age data of some volcanic fields that have been published. The time spans of ECB and EUB are from several minutes to years. In lava flows, cooling crust is distributed above and below ECB and EUB; in pyroclastic flows, airfalls and lahars, a fine layer below these boundaries has no discernable erosion at every part of the boundary. EUB may be curved or cross curved and jagged. The scale of ECB/EUB is dependent on the scale of lava flow or pyroclastic flows. The time span of EIUB is from decades to thousands of years. There is also weathered crust under EIUB and sedimentary rock beds overlie EIUB. In most instances, weathered crust and thin sedimentary beds are associated with each other laterally. The boundary is a smooth curved plane. The scale of EIUB is dependent on the scale of the volcano or volcano groups. The characteristics of TUB are similar to EIUB's. The time interval of TUB is from tens of thousands to millions of years. The scale of TUB depends on the scale of the basin or volcanic field. Both the lab data and logging data of wells in the Songliao Basin reveal that the porosity is greatly related to the boundaries in the lava flows. There is a high-porosity belt below ECB, EUB or EIUB, and the porosity decreases when it is apart from the boundary. The high-porosity belt below ECB and EUB is mainly contributed by primary porosity, such as vesicles. The high-porosity belt below EIUB is mainly contributed by primary and secondary porosity, such as association of vesicles and spongy pores, so the area near the boundary in lava flows is a very important target for reservoirs.

Background: This study aims to introduce the clinical application value of popliteal vein puncture in the supine position under ultrasound guidance and compare this method with popliteal vein puncture in the prone position., Methods: Endovascular operations for nonthrombotic iliac vein lesion patients using popliteal vein access were performed during the period from July 2019 to August 2022 at the Zhongshan Hospital (Xiamen), Fudan University, and Shanghai Xuhui District Central Hospital. Patients were randomly divided into supine position group and prone position group. All of the patients were punctured under ultrasound guidance. The procedure duration time for popliteal vein puncture, visual analog scale (VAS) scores, and postoperative complications were recorded and compared between the 2 groups., Results: Totally 120 patients were included in this study, in which 60 patients were enrolled in the supine position group and 60 patients were enrolled in the prone position group. The median procedure time from puncture to iliofemoral venography was 5.97 min (interquartile range 5.78 min-6.03 min) and 28.76 min (interquartile range 26.84 min-29.83 min; P < 0.01 (in the supine position and prone position group, respectively. The median time from puncture to access sheath insertion was 5.05 min (interquartile range 4.88 min-5.13 min) and 5.03 min (interquartile range 4.93 min-5.12 min; P = 0.607) in the supine position and prone position groups, respectively. The median VAS value was 3 (interquartile range 2-3) and 8 (interquartile range 7-9, P < 0.01) in the supine position and prone position groups, respectively. In the supine position group, one case of arterial branch injury was observed after operation and was successfully managed by ultrasound-guided compression., Conclusions: Popliteal vein puncture in the supine position under ultrasound guidance is safe, significantly reduces the overall operation time without changing position, and relieves the discomfort of patients., (Copyright © 2024 Elsevier Inc.

Two Gram-stain-negative, aerobic, rod-shaped, non-endospore-forming bacteria, designated as strain MH1 T and MH2 T , were isolated from branches of wilted pepper plants ( Capsicum annuum ) collected from a farmland in Machong town, Guangdong, China, and investigated using a polyphasic approach. MH1 T grew at temperatures of 4-42 °C (optimum 28 °C), with 0-6.0 % (w/v) NaCl and at pH 4.0-10.0 (optimum pH 4.0). MH2 T grew at temperatures of 4-42 °C (optimum 28 °C), with 0-6.0% (w/v) NaCl and at pH 4.0-10.0 (optimum pH 5.0). Analysis of the 16S rRNA gene sequence indicated that MH1 T belongs to Stenotrophomonas and MH2 T belongs to Pseudomonas . Genome-based phylogenetic analysis further established that MH1 T shares the closest evolutionary relationships with Stenotrophomonas humi DSM 18929 and Stenotrophomonas terrae DSM 18941, and MH2 T is sister to Pseudomonas wayambapalatensis RW3S1. Whole-genome comparisons between MH1 T and known Stenotrophomonas species revealed average nucleotide identity (ANI) values up to 84.5%, as well as digital DNA-DNA hybridization (dDDH) values up to 28.3%, both substantially lower than the accepted thresholds for species delineation (ANI: 95%; dDDH: 70%). The ANI and dDDH values between MH2 T and known Pseudomonas species were at most 94.6 and 59.2 %, respectively. Additional biochemical and physiological analyses further support that MH1 T and MH2 T represent a novel species in Stenotrophomonas and Pseudomonas , respectively. Notably, the differences in carbon source utilization could differentiate MH1 T and its close relatives in Stenotrophomonas . The major fatty acids were iso-C 15 : 0 , iso-C 16 : 0 and iso-C 14 : 0 for MH1 T and were C 16 : 0 , C 18 : 1  ω7c/C 18 : 1  ω6c (summed feature 8), C 16 : 1  ω7c/C 16 : 1  ω6c (summed feature 3) and C 17 : 0 cyclo for MH2 T . Therefore, we propose a new species Stenotrophomonas capsici sp. nov., with MH1 T (=GDMCC 1.3749 T =JCM 36317 T ) as the type strain, and a new species Pseudomonas machongensis sp. nov., with MH2 T (=GDMCC 1.3750 T =JCM 36318 T ) as the type strain. The MH1 T genome has a size of 4.18 Mb and a GC-content of 67.19 mol%, while the MH2 T genome has a size of 5.71 Mb and a GC-content of 63.12 mol%.

Objectives: The aim of this study was to report the long-term outcomes of proximal thoracic endovascular aortic repair (TEVAR) for chronic Stanford type B aortic dissection (cTBAD)., Methods: We retrospectively analyzed the clinical data of 48 cases of patients with cTBAD who underwent proximal TEVAR in Zhongshan Hospital Fudan University from January 2010 to September 2013. The preoperative and postoperative imaging examinations, overall survival rate, aortic-related survival rate, and freedom from reintervention rate data were collected to evaluate aortic remodeling and clinical outcomes. The enrolled patients received follow-up at 1, 3, 6, and 12 months following treatment and annually thereafter., Results: A total of 48 patients (mean age, 58.3 ± 10.6 years; men:women, 40:8) were included, of which 38 cases (79.2%) were uncomplicated dissection and 10 cases (20.8%) were complicated. The mean follow-up time was 48.7 ± 40 months (1-120 months). The mean time interval from the initial procedure to reintervention was 50.6 ± 32.7 months (11-98 months). The following changes were observed at preoperative versus last follow-up timepoints. Descending aortic level: true lumen, 19.2 ± 7.01 mm vs. 36.9 ± 9.53 mm ( p < 0.001); false lumen, 30.47 ± 15.89 mm vs. 19.16 ± 15.33 mm ( p < 0.001); maximum diameter, 49.67 ± 13.96 mm vs. 56.66 ± 14.95 mm ( p = 0.018). Diaphragm level: true lumen, 16.24 ± 5.41 mm vs. 24.41 ± 8.04 mm ( p < 0.001); false lumen, 12.37 ± 11.49 mm vs. 14.92 ± 12.25 mm ( p = 0.196); and maximum diameter, 34 ± 7.81 mm vs. 38.04 ± 7.7 mm ( p < 0.001). The freedom from reintervention rate was 81% in 5 years and 50.6% in 10 years. The overall 10-years survival rate was 83% (6 of 48), and the aortic-related survival rate was 92.3% (3 of 48)., Conclusions: TEVAR is a safe and effective proximal repair intervention for cTBAD that can reliably induce the positive remodeling of the descending aorta., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: Dyslipidemia is one of the major public health problems in China. It is characterized by multisystem dysregulation and inflammation, and oxidant/antioxidant balance has been suggested as an important factor for its initiation and progression. The objective of this study was to determine the relationship between prevalence of dyslipidemia and measured changes in the levels of proinflammatory cytokines (IL-6, TNF-a, and MCP-1), thiobarbituric acid-reactant substances (TBARS), and serum total antioxidant capacity (TAC) in serum samples., Study Design: A cross-sectional survey with a purposive sampling of 2,631 enrolled participants (age 18-85 years) was performed using the adult population of long-term residents of the municipality of east coast China in Fujian province between the years 2017 and 2019. Information on general health status, dyslipidemia prevalence, and selected mediators of inflammation was collected through a two-stage probability sampling design according to socioeconomic level, sex, and age., Methods: The lipid profile was conducted by measuring the levels of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG) with an autoanalyzer. Dyslipidemia was defined according to National Cholesterol Education Program Adult Treatment Panel III diagnostic criteria, and patients with it were identified by means of a computerized database. Serum parameters including IL-6/TNF-a/MCP-1, TBARS, and TAC were measured in three consecutive years. Familial history, education level, risk factors, etc. were determined. The association between dyslipidemia and serum parameters was explored using multivariable logistic regression models. Sociodemographic, age, and risk factors were also investigated among all participants., Results: The mean prevalence of various dyslipidemia in the population at baseline (2017) was as follows: dyslipidemias, 28.50%; hypercholesterolemia, 26.33%; high LDL-C, 26.10%; low HDL-C, 24.44%; and hypertriglyceridemia, 27.77%. A significant effect of aging was found among all male and female participants. The mean levels of serum Il-6/TNF-a/MCP-1 were significantly higher in all the types of dyslipidemia among male participants. Female participants with all types of dyslipidemia but low HDL-C showed an elevation of IL-6 and MCP-1 levels, and those with dyslipidemias and hypercholesterolemia presented higher levels of TNF-a compared to the normal participants. The oxidative stress marker TBARS increased among all types of dyslipidemia except hypertriglyceridemia. All participants with different types of dyslipidemia had a lower total antioxidant capacity. Correlation analysis showed that cytokines and TBARS were positively associated with age, obesity, and diabetes mellitus, but not sex, sedentary leisure lifestyle, hypertension, and CVD/CHD history. The activity of TAC was negatively associated with the above parameters., Conclusions: The correlation between the prevalence of dyslipidemia and the modification of inflammation status was statistically significant. The levels of proinflammatory cytokines, oxidative stress, and antioxidant capacity in serum may reflect the severity of the lipid abnormalities. These promising results further warrant a thorough medical screening in enhanced anti-inflammatory and reduced oxidative stress to better diagnose and comprehensively treat dyslipidemia at an early stage., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Hong, Lin, Ye, Yang, Huang, Duan and Xie.)
