The role of wave-induced mixing in spring phytoplankton bloom in the South Yellow Sea.

Using an ecosystem model, we simulated the spatiotemporal distribution of phytoplankton and studied its spring bloom (SPB) in the South Yellow Sea, aiming to gain a comprehensive understanding of the physical-biological mechanism, in particular the role of wave-induced mixing in the SPB. By incorporating wave mixing into the model, patterns of the SPB are obtained that are consistent with observations. The significant bloom occurs in April, supported by favorable conditions of nutrients, temperature, transparency, solar radiation, and wind speed that favor rapid algal growth in the upper mixed water.

Research on Unsupervised Low-Light Railway Fastener Image Enhancement Method Based on Contrastive Learning GAN.

The railway fastener, as a crucial component of railway tracks, directly influences the safety and stability of a railway system. However, in practical operation, fasteners are often in low-light conditions, such as at nighttime or within tunnels, posing significant challenges to defect detection equipment and limiting its effectiveness in real-world scenarios. To address this issue, this study proposes an unsupervised low-light image enhancement algorithm, CES-GAN, which achieves the model's generalization and adaptability under different environmental conditions.

Lymphovascular invasion predicts disease-specific survival in node-negative esophageal squamous cell carcinoma patients after minimally invasive esophagectomy.

Introduction: Lymphovascular invasion (LVI) is reported to be a potential prognostic predictor in esophageal squamous cell carcinoma (ESCC) patients.

Aim: To investigate the prognostic value of LVI in ESCC node-negative patients after minimally invasive esophagectomy (MIE).

Material And Methods: 1406 consecutive ESCC patients who underwent MIE were reviewed retrospectively.

Short- and long-term outcomes of prophylactic thoracic duct ligation during thoracoscopic-laparoscopic McKeown esophagectomy for cancer: a propensity score matching analysis.

Background: Chylothorax remains a challenging and potentially life-threatening postoperative complication after minimally invasive esophagectomy (MIE). The effect of intraoperative prophylactic thoracic duct ligation on preventing postoperative chylothorax still remains controversial. Moreover, the potential impact of thoracic duct ligation on long-term outcome after MIE has not been well established.

The Postoperative outcomes of thoracoscopic-laparoscopic Ivor-Lewis surgery plus D2 celiac lymphadenectomy for patients with adenocarcinoma of the esophagogastric junction.

Objectives: Adenocarcinoma of the esophagogastric junction (AEG) is one of the most aggressive and poor prognosis cancers. To date, no standard procedures have been established for the surgical treatment of Siewert type II. In this study, we proposed the approach of thoracoscopic-laparoscopic Ivor-Lewis surgery plus D2 celiac lymphadenectomy (TLILD2) and aimed to investigate the patterns of lymph node metastasis and long-term survival.

Overexpression of U three protein 14a (UTP14a) is associated with poor prognosis of esophageal squamous cell carcinoma.

Background: Esophageal squamous cell carcinoma (ESCC) is one of the most aggressive and lethal cancers lacking valid prognostic biomarkers. As an essential component of a large ribonucleoprotein complex, U Three Protein 14a (UTP14a) might play important roles in human tumorigenesis. However, the clinical significance and functions of UTP14a in ESCC still remain unclear.

Distribution characteristics of microplastics in the seawater and sediment: A case study in Jiaozhou Bay, China.

As a newly identified form of pollutant in the ocean, microplastics are receiving more and more attention from researchers. In order to evaluate the potential impact of microplastics, it is important to have comprehensive knowledge of the current microplastic situation. This study analyzed the abundance, polymer type, size, shape and color of microplastics in the seawater and sediments of Jiaozhou Bay, China, a semi-enclosed bay highly affected by surrounding human activities.

Propensity-Matched Analysis Comparing Survival After Hybrid Thoracoscopic-Laparotomy Esophagectomy and Complete Thoracoscopic-Laparoscopic Esophagectomy.

Background: Hybrid thoracoscopic-laparotomy esophagectomy (hTE) and complete thoracoscopic-laparoscopic esophagectomy (cTLE) are the two most frequently used minimally invasive esophagectomy (MIE) procedures and are broadly utilized for esophageal cancer. We evaluated differences in short- and long-term outcomes between hTE and cTLE in patients with esophageal squamous cell carcinoma (ESCC).

Methods: Patients who underwent MIE for ESCC between September 2009 and February 2016 were included in this retrospective study.

Intraoperative conversion does not affect the oncological outcomes of minimally invasive esophagectomy for treatment of esophageal cancer.

Background: The aim of this study is to summarize the causes and implications of intraoperative conversion from minimally invasive esophagectomy (MIE) to open thoracotomy, and to evaluate the effect on long-term survival.

Methods: There were 293 thoracoscopic esophagectomies for esophageal squamous cell carcinoma (ESCC) of the thoracic esophagus performed by the authors from September 2009 to August 2015. Totally, 257 patients were enrolled in this study.

The effect of postoperative complications on survival of patients after minimally invasive esophagectomy for esophageal cancer.

Background: Minimally invasive esophagectomy (MIE) has been shown to be a feasible technique for the treatment of esophageal cancer; however, its postoperative morbidity remains high. This retrospective study aimed to evaluate the effect of postoperative complications on long-term outcomes in patients who have undergone MIE for esophageal squamous cell carcinoma (ESCC).

Methods: This retrospective study enrolled patients who had undergone MIE for ESCC between September 2009 and November 2014; all procedures were performed by a single surgical team.

Do alterations in plasma albumin and prealbumin after minimally invasive esophagectomy for squamous cell carcinoma influence the incidence of cervical anastomotic leak?

Background: Anastomotic leak (AL) remains a challenging and bothersome complication of minimally invasive esophagectomy (MIE). In this retrospective study, we measured the perioperative albumin (ALB) and prealbumin (PA) of patients who underwent MIE, and investigated the relationship between the occurrence of AL and the altering levels of ALB/PA.

Patients And Methods: Sixty patients underwent video-assisted thoracoscopic-laparoscopic esophagectomy between September 2013 and August 2014.

Should stage T2 esophageal squamous cell carcinoma be subclassified?

Background: In patients with esophageal squamous cell carcinoma (ESCC), pathologic examination allows T2 tumors to be further subclassified according to whether the circular or longitudinal muscle layers are invaded. Therefore, we aimed to investigate whether subclassifying the T2 stages can aid in determining the prognosis for patients with ESCC.

Methods: The clinical and pathologic characteristics of 85 ESCC patients with T2 tumors who underwent thoracoscopic esophagectomy between 2008 and 2013 were retrospectively analyzed.

Lateral position could provide more excellent hemodynamic parameters during video-assisted thoracoscopic esophagectomy for cancer.

Background: Thoracoscopic esophagectomy is a feasible technique that has been shown to be safe for the treatment of esophageal cancer. There continues to be controversy about the optimal position during thoracoscopic esophagectomy. In this study, we compared the intraoperative hemodynamic parameters, clinical pathological characteristics, as well as postoperative complications in patients who underwent thoracoscopic esophagectomy in the prone position (PP) or left-lateral decubitus position (LDP).

Prevention of postoperative chylothorax with thoracic duct ligation during video-assisted thoracoscopic esophagectomy for cancer.

Background: Minimally invasive esophagectomy (MIE) is a feasible technique that has been shown to be safe for the treatment of esophageal cancer. Chylothorax remains a challenging and potentially life-threatening postoperative complication of MIE. In this retrospective series, we evaluated the results of preventive intraoperative thoracic duct ligation in patients who underwent video-assisted thoracoscopic esophagectomy for cancer.
