Esophageal Hematoma After Severe Vomiting.

A male patient developed hematemesis and chest pain after severe vomiting. Gastroscopy showed a linear hematoma from the esophageal entrance to the cardia. Enhanced CT of the esophagus revealed a high-density shadow in the middle of the esophagus.

Impact of breakfast skipping on esophageal health: A mendelian randomization study.

Background & Aims: Previous studies have indicated that, in addition to the types of food consumed, eating habits are also associated with the risk of esophageal diseases. Some studies have suggested a possible link between breakfast skipping and esophageal tumors as well as gastroesophageal reflux disease. However, it remains unclear whether breakfast skipping has a causal relationship with esophageal diseases.

Peimine induces apoptosis of glioblastoma cells through regulation of the PI3K/AKT signaling pathway.

Glioblastoma (GBM) is one of the most malignant forms of intracranial tumors, with high mortality rates and invariably poor prognosis, due to the limited clinical treatment strategies available. As a natural compound, peimine's favorable pharmacological activities have been widely revealed. However, potential inhibitory effects of peimine on GBM have not been explored.

Daphnoretin inhibits glioblastoma cell proliferation and metastasis via PI3K/AKT signaling pathway inactivation.

Glioblastoma (GBM) was the most malignant intracranial tumor with high mortality rates and invariably poor prognosis due to its limited clinical treatments. The urgent need to develop new therapeutic drugs for GBM treatment is evident. As a coumarin derivative, daphnoretin's favorable pharmacological activities have been widely documented.

Isorhamnetin: what is the evidence for its antitumor potential and beyond?

Isorhamnetin (ISO) is a phenolic compound belonging to flavonoid family, showcasing important pharmacological activities such as antitumor, anti-inflammation, and organ protection. ISO is predominantly extracted from . This plant is well-known in China and abroad because of its "medicinal and food homologous" characteristics.

Zeaxanthin impairs angiogenesis and tumor growth of glioblastoma: An in vitro and in vivo study.

Objectives: To investigate the therapeutic effects of Zeaxanthin (Zea), one of the oxidized xanthophyll carotenoids belonging to the isoprenoids, on inhibiting the angiogenesis and tumor growth of glioblastoma (GBM) via an in vitro and in vivo study.

Methods: The effects of Zea on the proliferation, adhesion, migration and invasion of human GBM cell lines were detected by cell proliferation assay, cell adhesion assay and Transwell assay. The effect of Zea on angiogenesis was detected by rat aortic ring assay and human umbilical vein endothelial cells (HUVEC) in vitro tube formation assay.

Highly sensitive flexible heat flux sensor based on a microhole array for ultralow to high temperatures.

With the growing demand for thermal management of electronic devices, cooling of high-precision instruments, and biological cryopreservation, heat flux measurement of complex surfaces and at ultralow temperatures has become highly imperative. However, current heat flux sensors (HFSs) are commonly used in high-temperature scenarios and have problems when applied in low-temperature conditions, such as low sensitivity and embrittlement. In this study, we developed a flexible and highly sensitive HFS that can operate at ultralow to high temperatures, ranging from -196 °C to 273 °C.

Nrf2 signaling pathway: current status and potential therapeutic targetable role in human cancers.

Cancer is a borderless global health challenge that continues to threaten human health. Studies have found that oxidative stress (OS) is often associated with the etiology of many diseases, especially the aging process and cancer. Involved in the OS reaction as a key transcription factor, Nrf2 is a pivotal regulator of cellular redox state and detoxification.

Flexible thin film thermocouples: From structure, material, fabrication to application.

Flexible thin-film thermocouples (TFTCs) have been garnering interest as temperature sensors due to the advantages of being flexible, ultrathin, and ultralight. Additionally, they have fast response times and enable detection of temperature. These properties have made them suitable for applications such as wearable electronics, healthcare, portable personal devices, and smart detection systems.

Supplementary education can improve the rate of adequate bowel preparation in outpatients: A systematic review and meta-analysis based on randomized controlled trials.

Background: Colonoscopy is widely used for the screening, diagnosis and treatment of intestinal diseases. Adequate bowel preparation is a prerequisite for high-quality colonoscopy. However, the rate of adequate bowel preparation in outpatients is low.

Influences of RF Magnetron Sputtering Power and Gas Flow Rate on a High Conductivity and Low Drift Rate of Tungsten-Rhenium Thin-Film Thermocouples.

Thin-Film Thermocouples (TFTCs) are characterized by their high spatial resolutions, low cost, high efficiency and low interference on the air flow. However, the thermal stability of TFTCs should be further improved for application since their accuracy is influenced by joule heat and temperature time drift. In this paper, 3D molecular dynamics and finite element analysis are used for structural design.

Optimization on thermoelectric characteristics of indium tin oxide/indium oxide thin film thermocouples based on screen printing technology.

In this work, indium tin oxide (ITO)/indium oxide (InO) thin film thermocouples (TFTCs) were prepared based on screen printing technology for high temperature measurement. With terpilenol as solvent, epoxy resin and polyether amine as binders and glass powders as additives, the ITO and InO slurries were printed onto the AlO substrate to form thermocouples. The effect on thermoelectric properties of the TFTCs with heat treatment and different contents of additives was investigated through microstructure observation and thermal cycle test.

Disturbance compensation of a multiaperture imaging system based on a coupling rotating prism using an improved model compensation control.

In this paper, a cascade double-loop control (DLC) combined with modeling compensation methods is proposed to improve the tracking precision of the multiaperture imaging system (MAIS). The application of the flexible thin-wall ring mechanism in the coupling rotating prism (CRP) system causes a series of tracking and pointing challenges. Disturbances such as friction, shaft deformation, and model perturbation significantly deteriorate the tracking and pointing accuracy of the CRP.
