Dispersion, radiological dose assessment, risk evaluation, and emergency response of radioactive materials based on WRF-HYSPLIT modeling.

Accurate prediction of radionuclide dispersion is essential for radiation hazard prevention, yet predictive studies remain limited. This study employed the weather research and forecasting (WRF) model to generate a high-resolution meteorological data for the hybrid single particle lagrangian integrated trajectory (HYSPLIT) model to simulate the atmospheric transport of iodine-131 (I). The calculation results of the real-time impact of radioactive emissions were obtained by first solving the gridded standard response distribution, then multiplying the coefficients according to the actual emission situation.

Flexible ultrathin metasurface with open-ring spiral resonators for SNR enhancement in low-field 0.2 T MRI.

Low-field magnetic resonance imaging (MRI) systems (<0.5 T) have emerged as increasingly valuable tools for emergency and bedside imaging due to their cost-effectiveness and portability, but their adoption is limited by low signal-to-noise ratio (SNR). Conventional optimization methods offer limited improvements, while current metasurface technologies face challenges related to clinical integration, such as excessive dimensionality, and inadequate SNR enhancement at low magnetic field strengths.

The Effect of Thermal-Softened Endotracheal Tubes on Postoperative Sore Throat and Other Complications-A Systematic Review and Meta-Analysis.

: Endotracheal tube (ETT) intubation during general anesthesia (GA) is commonly associated with postoperative sore throat. This study aimed to evaluate whether thermal-softened ETTs reduce the postoperative sore throat incidence in patients undergoing elective surgery under GA. : We conducted a comprehensive search of the literature across PubMed, Cochrane Library, and EMBASE to identify randomized controlled trials (RCTs) evaluating the effect of thermal-softened ETTs on postoperative sore throat in patients undergoing elective surgeries under GA.

Cynarin protects against seizures and neuronal death in a rat model of kainic acid-induced seizures.

The potential therapeutic value of cynarin, a phenolic compound derived from artichoke, in treating epilepsy has not yet been reported. The present study evaluated the effects of cynarin on a kainic acid (KA)-induced seizure rat model and its potential mechanism. Cynarin was administered through oral gavage at a dosage of 10 mg kg daily for 7 days before the induction of seizures with KA (15 mg kg) intraperitoneal injection.

Discovery of tri(indolyl)methanes as potent and selective inhibitors against human carboxylesterase 2.

Human carboxylesterase 2A (CES2A) plays a crucial role in the hydrolysis and metabolic activation of esters and amides. There is increasing evidence that development of CES2A inhibitors to modulate the hydrolysis of ester drugs will increase the potency of these drugs or reduce their side effects. In this study, three sets of indole analogues (4a-j, 5a-k, 6a-e) were designed and synthesized.

Reduction in presynaptic glutamate release and the prevention of glutamate excitotoxicity by lupeol in rats.

This study aimed to investigate whether lupeol, a pentacyclic triterpenoid, affects glutamate release in isolated nerve terminals (synaptosomes) from the rat cerebral cortex and whether lupeol affects the excitotoxicity induced by kainic acid (KA) in rats. In rat cerebrocortical synaptosomes, lupeol reduced glutamate release in a manner that could be blocked by extracellular Ca-free medium or P/Q-type Ca channel antagonism. The synaptosomal membrane potential was not affected by lupeol treatment.

An iteratively optimized downscaling method for city-scale air quality forecast emission inventory establishment.

Air quality models (AQMs) are pivotal in forecasting air quality and shaping pollution control strategies. Nonetheless, the effectiveness of AQMs is often compromised in many cities due to the absence of accurate local emission inventories. To address this gap, this study presents a novel AQM-ready emission inventory generation technique with iterative optimization ability for city-scale applications in China.

Albiflorin Decreases Glutamate Release from Rat Cerebral Cortex Nerve Terminals (Synaptosomes) through Depressing P/Q-Type Calcium Channels and Protein Kinase A Activity.

The purpose of this study was to investigate whether and how albiflorin, a natural monoterpene glycoside, affects the release of glutamate, one of the most important neurotransmitters involved in neurotoxicity, from cerebrocortical nerve terminals (synaptosomes) in rats. The results showed that albiflorin reduced 4-aminopyridine (4-AP)-elicited glutamate release from synaptosomes, which was abrogated in the absence of extracellular Ca or in the presence of the vesicular glutamate transporter inhibitor or a P/Q-type Ca channel inhibitor, indicating a mechanism of action involving Ca-dependent depression of vesicular exocytotic glutamate release. Albiflorin failed to alter the increase in the fluorescence intensity of 3,3-diethylthiacarbocyanine iodide (DiSC(5)), a membrane-potential-sensitive dye.
