Improved Method for the Calculation of the Air Film Thickness of an Air Cushion Belt Conveyor.

The air film thickness is an important parameter of an air cushion belt conveyor, which directly affects the compressed air supply power and operating resistance of the system. Therefore, it is important to calculate the bottom thickness of the gas film accurately in the design stage. A calculation method for the thickness of a conveyor air cushion was derived based on the mathematical model of the air cushion flow field for a multi row uniformly distributed air cushion structure.

Subanesthetic propofol alleviates chronic stress-induced anxiety by enhancing VTADA neurons' activity.

Anxiety, a common mental disorder, imposes significant clinical and economic burdens. Previous studies indicate that propofol has anxiolytic effects at anesthetic doses. However, the risks associated with general anesthesia limit its application in anxiety treatment.

A randomized controlled trial investigating the impact of early goal-directed sedation dominated by dexmedetomidine on cerebral oxygen metabolism and inflammatory mediators in patients with severe brain injury.

Objective: The aim of this study is to assess the neuroprotective efficacy of early goal-directed sedation (EGDS) primarily governed by dexmedetomidine in patients experiencing severe traumatic brain injury, and to elucidate its potential underlying mechanisms.

Application of a Near-Infrared Fluorescence Probe Based on Perylene Bisimide in the Detection of Heparin.

Heparin is widely used to treat thrombosis because it is an effective anticoagulant. However, excessive use of heparin can lead to an increased risk of bleeding, which makes the quantitative detection of heparin very important. An amphiphilic perylene bisimide molecule (denoted PBI-9) was developed, which presented a near-infrared emission peak at 730 nm when it was aggregated.

A Ratiometric Time-Gated Luminescence Probe for Imaging HO in Endoplasmic Reticulum of Living Cells and Its Application to Smartphone-Guided Bioimaging.

The significance of HO as a marker of reactive oxygen species (ROS) and oxidative stress in living organisms has spurred growing interest in its roles in inflammation and disease progression. In this report, a ratiometric time-gated luminescence (RTGL) probe is proposed based on mixed lanthanide complexes, ER-BATTA-Tb/Eu, for imaging the HO generation both in vitro and in vivo. Upon exposure to HO, the probe undergoes cleavage of the benzyl boric acid group, releasing hydroxyl (─OH) groups, which significantly reduces the emission of the Eu complex while slightly increasing the emission of the Tb complex.

Relationship between intracranial pressure and neurocognitive function among older adults after radical resection of rectal cancer.

Background: Older patients are prone to postoperative cognitive decline after laparoscopic rectal cancer surgery, which may be associated with increased intraoperative intracranial pressure (ICP). This study investigated the correlation between intraoperative ICP changes, as indicated by measurements of the optic nerve sheath diameter (ONSD) using ultrasonography, and subsequent cognitive function to provide better patient care.

Aim: To evaluate changes in ICP and associated postoperative neurocognition in older adults after laparoscopic radical resection for rectal cancer.

Using machine learning to develop a stacking ensemble learning model for the CT radiomics classification of brain metastases.

The objective of this study was to explore the potential of machine-learning techniques in the automatic identification and classification of brain metastases from a radiomic perspective, aiming to improve the accuracy of tumor volume assessment for radiotherapy. By using various machine-learning algorithms, including random forest, support vector machine, gradient boosting machine, XGBoost, decision tree, artificial neural network, k-nearest neighbors, LightGBM, and CatBoost algorithms, a stacking ensemble model was developed to classify gross tumor volume (GTV), brainstem, and normal brain tissue based on radiomic features. Multiple evaluation metrics, including the specificity, sensitivity, negative predictive value, positive predictive value, accuracy, Matthews correlation coefficient, and the Youden index, were used to assess the model's performance.

An annealing approach to form a nanotube from graphdiyne ribbon: a theoretical prediction.

A precisely controllable heat treatment process is critical for nanofabrication.

Regulating LiS Deposition and Accelerating Conversion Kinetics through Intracavity ZnS toward Low-Temperature Lithium-Sulfur Batteries.

The uncontrolled deposition behavior and sluggish conversion kinetics of the discharging product (solid LiS) severely deteriorate the electrochemical performance of lithium-sulfur (Li-S) batteries, especially under high S loading and low-temperature conditions. Herein, a multifunctional S cathode host consisting of ZnS nanoparticles (NPs) confined in hollow porous carbon spheres (ZnS@HPCS) is synthesized via a unique capillary force-driven melting-diffusion strategy. The porous carbon shell of ZnS@HPCS provides a space-confined reservoir for soluble polysulfides and solid LiS, while the intracavity ZnS NPs trap polysulfides, induce LiS inside deposition, and accelerate conversion kinetics.

Production, Characterization, and Application of Hydrophobin-Based IR780 Nanoparticles for Targeted Photothermal Cancer Therapy and Advanced Near-Infrared Imaging.

As a promising approach for breast cancer treatment, photothermal therapy (PTT) features high spatial selectivity, noninvasiveness, and minimal drug resistance. IR780 (a near-infrared fluorescent dye) serves as an effective photosensitizer in PTT cancer therapy. However, the clinical application of IR780 in PTT has been hindered by its poor water solubility and unstable photostability.
