There has been much discussion about the evolution of the Southeastern CAOB in the past two decades [Tang, 1990; Hong et al., 1994; Xiao et al., 2003; Li, 2006; Chen et al., 2009; Jian et al., 2010]. Most people believed that the Palaeozoic Asia ocean was closed along the Solonker suture at Permian...

Objective: To investigate the ultrasonographic characteristics and outcomes of fetal umbilical-portal-systemic venous shunts (UPSVS). Methods: UPSVS cases at a single center between January 2015 and December 2022 were retrospectively investigated. The ultrasonographic features, types, and postnatal...

Established findings in nanostructure mechanics have highlighted the limitations of classical continuum theories in predicting mechanical behavior at the nanoscale, particularly for nanostructures like nanorods and nanowires used in nanoelectromechanical systems, sensors, resonators, memory systems,...

This paper investigates the temperature detection and prediction in S355NL large ring forgings during the forging process. Initially, the process was modeled using a high-precision finite element model. The contact heat transfer coefficient between S355NL low alloy steel and 5CrNiMo die steel was de...

BackgroundVisual fatigue, commonly attributed to excessive eye use or dry conditions, is traditionally associated with deficiencies in liver and kidney yin in Chinese medicine. However, its metabolic aspects remain largely unexplored.MethodsLevothyroxine sodium combined with tail-clip stimulation in...

Mixed silage can disrupt the girder structure of rape straw, and thus facilitate ruminal degradation. Further investigation is warranted to validate this observation in vivo. The objective of this study was to investigate the degradation kinetics and bacterial colonization of mixed silage during dig...

The deep crustal continental components and architecture of the Central Asian Orogenic Belt have long been a matter of debate [Wang et al., 2009; Kröner et al., 2014; Xiao et al., 2015; Yang et al., 2017]. We present an integrated study of geochronological and Hf-inzircon isotopic data for xenocryst...

BackgroundOne-lung ventilation (OLV) with double-lumen tubes (DLT) are prone to complications such as airway injury and hypoxemia. It is not clear whether a two-lung ventilation (TLV) with single-lumen tube (SLT) is beneficial for patients undergoing totally endoscopic cardiac valve surgery (TECVS)....

Proper nutrient management and planting density can effectively improve crop yields and economic efficiency. Optimized fertilization and high-density planting measures have gained attention for their ability to balance high crop yields with efficient nitrogen utilization. High and stable yield of ma...

Background Coronary artery disease is characterized by chronic immune‐inflammation, excessive endoplasmic reticulum (ER) stress, and platelet hyperactivity; however, whether there is a signaling hub linking these events remains unclear. Here, we identified that TREM2 (triggering receptor expressed o...

Tumor-initiated emergency granulopoiesis results in expansion of the circulating neutrophil compartment and neutrophil recruitment into the tumor microenvironment (TME), which may in turn promote tumor progression. Although an elevated circulating neutrophil-to-lymphocyte ratio (cNLR) has repeatedly...

Purpose SWOG S1609 Dual Anti-CTLA-4 and anti-PD-1 blockade in Rare Tumors (DART) studied the efficacy of ipilimumab combined with nivolumab across multiple rare tumor types. We report the results of the pancreatic neuroendocrine neoplasm (PNEN) cohort.Experimental design Treatment consisted of ipili...
