The procedure time in the LCE group (median, 20.5 min) was significantly (
= 0.024) shorter than that in the SCE group (median, 25.1 min). The insertion time in the LCE group (median, 2.0 min) was significantly (
= 0.0049) shorter than that in the SCE group (median, 6.0 min). A sub-analysis of the procedure difficulties showed that the insertion time in the LCE group (median, 5.0 min) was significantly shorter than that in the SCE group (median, 8.5 min).
Both LCE and SCE can be used for C-SEMS; however, LCE is more suitable than SCE as it achieved a faster and equally efficacious C-SEMS placement as that of SCE.

Chronic heart failure (CHF) is a serious heart disease resulting from cardiac dysfunction. Oxidative stress is an important factor in aging and disease. Butein, however, has antioxidant properties. To determine the effect of butein on oxidative stress injury in rats, a CHF rat model was established.
The CHF rat model was induced by abdominal aortic coarctation (AAC). Rats in CHF+butein and sham+butein group were given 100 mg/kg butein via gavage every day to detect the effect of butein on oxidative stress injury and myocardial dysfunction. The cardiac structural and functional parameters, including the left ventricular end-systolic dimension (LVESD), the left ventricular end-diastolic dimension (LVEDD), the left ventricular ejection fraction (LVEF), and the left ventricular fractional shortening (LVFS), were measured. Oxidative stress was measured through the production of reactive oxygen species (ROS), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT), and malondialdehyde (MDA). Cardiac injury markers like creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH), and aspartate aminotransferase (AST) were evaluated. Hematoxylin and eosin (H&E) staining was used to observe the myocardial cell morphology. The effect of butein on the extracellular signal-regulated kinase (ERK)/nuclear factor-E2 p45-related factor (Nrf2) signaling was confirmed by Western blot analysis.
Butein had a significant effect on CHF in animal models. In detail, butein inhibited oxidative stress, relieved cardiac injury, and alleviated myocardial dysfunction. Importantly, butein activated the ERK1/2 pathway, which contributed to Nrf2 activation and subsequent heme oxygenase-1 (HO-1) and glutathione cysteine ligase regulatory subunit (GCLC) induction.
In this study, butein inhibits oxidative stress injury in CHF rat model via ERK/Nrf2 signaling pathway.
In this study, butein inhibits oxidative stress injury in CHF rat model via ERK/Nrf2 signaling pathway.This article is aimed at studying the design and implementation of a football player training management system based on smart images. Based on the analysis of the importance of informatization for scientific football training, system performance requirements and intelligent image detection technology, the football player training management is designed. The overall architecture of the system, and the detailed design of each functional module of the system. It mainly includes football player information management module, football player training plan viewing module, training goal formulation module and training information feedback module. The realization of the training management system relies on intelligent image technology to detect and track athletes. Finally, the performance of the system was tested. The test results show that the expected response time of each module of the system when different numbers of users are accessed is within 3 seconds. The longest actual time is 2.64 s, and the actual shortest time is 1.18 s. It can be seen that the response time of the system meets the demand. At the same time, the system throughput rate meets the requirements of this article, and the user pass rate is also above 95%, indicating that the performance of the football player training management system designed in this article is better.According to prior work, persistent goal pursuit is a continuous process where persisting is a matter of resisting the urge to give up. In everyday goals, however, persistence is often episodic, and its causes are more complex. People pause and resume pursuit many times. Whether people persist reflects more than will power and motivation, it also reflects the other goals they pursue, their resources, and the attentional demands of daily life. People can fail to persist not just because they gave up, but also because they failed to act. We propose a general model of persistence that accommodates the complexity of episodic goals. We argue that persistent goal pursuit is a function of three processes resisting the urge to give up, recognizing opportunities for pursuit, and returning to pursuit. The broad factors that help and hurt persistence can be organized within these components. These components can also explain the mechanisms of four effective strategies for persistence removing distractions, using reminders, using implementation intentions, and forming habits. The recognizing-resisting-returning model integrates and improves on extant theories of persistence and goal pursuit and is consistent with empirical work from laboratory and naturalistic settings.Comprehensive sampling of the carbonate system in estuaries and coastal waters can be difficult and expensive because of the complex and heterogeneous nature of near-shore environments. We show that sample collection by community science programs is a viable strategy for expanding estuarine carbonate system monitoring and prioritizing regions for more targeted assessment. 'Shell Day' was a single-day regional water monitoring event coordinating coastal carbonate chemistry observations by 59 community science programs and seven research institutions in the northeastern United States, in which 410 total alkalinity (TA) samples from 86 stations were collected. Field replicates collected at both low and high tides had a mean standard deviation between replicates of 3.6 ± 0.3 μmol kg-1 (σ mean ± SE, n = 145) or 0.20 ± 0.02%. This level of precision demonstrates that with adequate protocols for sample collection, handling, storage, and analysis, community science programs are able to collect TA samples leading to hway to inventory monitoring assets, build partnerships with stakeholders, and expand education and outreach to a broader constituency.Infection diseases are among the top global issues with negative impacts on health, economy, and society as a whole. One of the most effective ways to detect these diseases is done by analysing the microscopic images of blood cells. Artificial intelligence (AI) techniques are now widely used to detect these blood cells and explore their structures. In recent years, deep learning architectures have been utilized as they are powerful tools for big data analysis. In this work, we are presenting a deep neural network for processing of microscopic images of blood cells. Processing these images is particularly important as white blood cells and their structures are being used to diagnose different diseases. In this research, we design and implement a reliable processing system for blood samples and classify five different types of white blood cells in microscopic images. We use the Gram-Schmidt algorithm for segmentation purposes. For the classification of different types of white blood cells, we combine Scale-Invariant Feature Transform (SIFT) feature detection technique with a deep convolutional neural network. To evaluate our work, we tested our method on LISC and WBCis databases. We achieved 95.84% and 97.33% accuracy of segmentation for these data sets, respectively. Our work illustrates that deep learning models can be promising in designing and developing a reliable system for microscopic image processing.COVID-19 is a world pandemic that has affected and continues to affect the social lives of people. Due to its social and economic impact, different countries imposed preventive measures that are aimed at reducing the transmission of the disease. Such control measures include physical distancing, quarantine, hand-washing, travel and boarder restrictions, lockdown, and the use of hand sanitizers. Quarantine, out of the aforementioned control measures, is considered to be more stressful for people to manage. When people are stressed, their body immunity becomes weak, which leads to multiplying of coronavirus within the body. Therefore, a mathematical model consisting of six compartments, Susceptible-Exposed-Quarantine-Infectious-Hospitalized-Recovered (SEQIHR) was developed, aimed at showing the impact of stress on the transmission of COVID-19 disease. From the model formulated, the positivity, bounded region, existence, uniqueness of the solution, the model existence of free and endemic equilibrium points, and local and global stability were theoretically proved. The basic reproduction number (R 0) was derived by using the next-generation matrix method, which shows that, when R 0 1 the endemic equilibrium is globally asymptotically stable. Moreover, the Partial Rank Correlation Coefficient (PRCC) method was used to study the correlation between model parameters and R 0. Numerically, the SEQIHR model was solved by using the Rung-Kutta fourth-order method, while the least square method was used for parameter identifiability. Furthermore, graphical presentation revealed that when the mental health of an individual is good, the body immunity becomes strong and hence minimizes the infection. Conclusively, the control parameters have a significant impact in reducing the transmission of COVID-19.
To compare the clinical effects of modified above-knee and conventional surgery with the stripping of the great saphenous vein of varicose veins of the lower extremities.
Clinical data of patients with a varicose vein of the lower extremity from May 2016 to May 2018 were collected. A retrospective study was conducted on the patients receiving modified above-knee and conventional surgery with the great saphenous vein stripping. The baseline characteristics and long-term follow-up data were compared between the groups.
There were no significant differences in baseline characteristics between the two groups (
> 0.05). The surgeries were successfully performed by the same group of surgeons under local anesthesia and neuraxial anesthesia. The hospital stay, operation time, intraoperative blood loss, total length, and number of incisions in the above-knee group were comparable to those in the conventional surgery group (
> 0.05). Cyclic GMP-AMP The incidence of saphenous nerve injury and subcutaneous hematoma in tive blood loss and complication incidences, and shorten the operative time. This gives evidence that the modified above-knee technique is worthy of clinical application.
Colorectal cancer (CRC), a common digestive tract tumor that contains colon and rectal cancer, is one of the three most common cancers globally. circRNAs are involved in the occurrence and development of CRC, but the mechanism of how they participate in this process remains unclear.
We adopted PCR for expression measure, CCK-8 for cell proliferation detection, Transwell for cell migration and invasion detection, and dual-luciferase reporter assays to detect the potential downstream targets of CCDC66 in CRC.
This study showed that circRNA CCDC66 was overexpressed in CRC tissues, and after knockdown, it inhibited the proliferation, migration, and invasion of CRC cells (RKO and HCT-116) in vitro. In addition, the dual-luciferase reporter assay showed that there was a binding site between circCCDC66 and miR-370, as well as between miR-370 and murine double minute 4 (MDM4). That is, circCCDC66 upregulated the expression of MDM4 through competitively binding to miR-370. The expression of circCCDC66 in CRC tissues was positively correlated with MDM4 and negatively correlated with miR-370.
