-propolis mixture attenuates airway inflammation in a mouse model of PM and ovalbumin-induced respiratory disease.

Airway inflammation driven by particulate matter (PM) exposure underlies diseases such as asthma and allergic rhinitis. Although conventional anti-inflammatory therapies exist, they often cause significant side effects. Natural plant extracts offer non-toxic alternatives with comparable efficacy.

Dynamic Lipidomic Remodeling and Clinical Correlations after Sleeve Gastrectomy in Obese Subjects.

Background: Sleeve gastrectomy (SG) is an effective and the most commonly performed surgical intervention for obesity. However, detailed studies on the underlying mechanisms, particularly those involving lipid metabolism, remain limited. This study aimed to identify novel pathways associated with the metabolic efficacy of SG by assessing alterations in the serum lipidomic profiles of obese subjects following surgery.

Enhanced UVC Responsivity of Heteroepitaxial α-GaO Photodetector with Ultra-Thin HfO Interlayer.

In this study, the influence of HfO interlayer thickness on the performance of heteroepitaxial α-GaO layer-based metal-insulator-semiconductor-insulator-metal (MISIM) ultraviolet photodetectors is examined. A thin HfO interlayer enhances the interface quality and reduces the density of interface traps, thereby improving the performance of UVC photodetectors. The fabricated device with a 1 nm HfO interlayer exhibited a significantly reduced dark current and higher photocurrent than a conventional metal-semiconductor-metal (MSM).

Cost-effectiveness of advanced hepatic fibrosis screening in individuals with suspected MASLD identified by serologic noninvasive tests.

Our study assessed the cost-effectiveness of screening for hepatic fibrosis in cases suspected of metabolic dysfunction-associated steatotic liver disease (MASLD) using serological noninvasive tests like the fatty liver index (FLI) and hepatic steatosis index (HSI). We applied a decision tree and Markov model from a healthcare system perspective to estimate life-years, quality-adjusted life-years (QALYs), costs, and the incremental cost-effectiveness ratio (ICER) for screening versus no screening in the United States. Prevalence of advanced hepatic fibrosis in individuals suspected of having MASLD was significantly higher when defined by FLI (10.

This study compared LDCT with contrast-enhanced chest computed tomography (CECT) in terms of recurrence detection and overall survival (OS) in patients two years after curative resection of NSCLC.

Materials And Methods: Among patients who underwent curative resection for NSCLC between January 2011 and December 2017 and survived for 2 years without recurrence, 2083 patients were included.

Anti-inflammatory effects of Elsholtzia ciliata extract on Poly I:C-treated RAW264.7 cells.

Ethnopharmacological Relevance: Inflammation is a vital biological response to noxious stimuli, including physical injury and pathogenic infection, and involves immune cells and various inflammatory mediators, limiting cell damage and eliminating pathogens. Although essential for healing, inflammation can cause symptoms, such as fever, swelling, pain, and itching, potentially reducing quality of life. Elsholtzia ciliata used in traditional medicine has numerous medicinal characteristics such as antiviral, antibacterial, antipyretic, diaphoretic, carminative, astringent, and diuretic effects.

Development of the Gut Microbial Immune and Epithelial Cellular System (GutMICS) to Investigate the Immunological Role of Gut Anaerobes.

The gut microbiota plays an essential role in host health by regulating gut barrier function and immune system homeostasis. However, research into the physiological and immunological functions of the gut microbiota using In Vitro models that mimic the immune environment of the gut remains limited. Herein, we developed the Gut Microbial Immune & Epithelial Cellular System (GutMICS), a device for coculturing anaerobic gut microbes with host cells, including intestinal epithelial and immune cells.

Comparison of Non-invasive Methods for Diagnosis of Non-alcoholic Fatty Liver Disease Before Bariatric Surgery and Postoperative Follow-up in Obese Patients.

Purpose: This study aims to identify the most accurate and useful non-invasive method to replace liver biopsy for the diagnosis of non-alcoholic fatty liver disease (NAFLD) before bariatric surgery and postoperative follow-up in morbidly obese patients.

Materials And Methods: This single-center study is a retrospective analysis of prospectively collected data from 68 morbidly obese patients who underwent laparoscopic sleeve gastrectomy with intraoperative liver biopsy. Preoperative non-invasive diagnostic methods, including fatty liver index, NAFLD fibrosis score, enhanced liver fibrosis score, FibroScan, magnetic resonance imaging-proton density fat fraction (MRI-PDFF), magnetic resonance spectroscopy (MRS)-PDFF, and magnetic resonance elastography (MRE) were compared against liver biopsy results.

Phase glides and self-organization of atomically abrupt interfaces out of stochastic disorder in α-GaO.

Disorder-induced ordering and remarkably high radiation tolerance in γ-phase of gallium oxide is a recent spectacular discovery at the intersection of the fundamental physics and electronic applications. Importantly, by far, these data were collected with initial samples in form of the thermodynamically stable β-phase of this material. Here, we investigate these phenomena starting from metastable α-phase and explain radically new trend occurring in the system.

Effects of shared decision-making on the prognosis of peritoneal dialysis patients.

Background: Chronic kidney disease (CKD) patients face critical decisions in choosing kidney replacement therapy such as hemodialysis (HD) or peritoneal dialysis (PD), which significantly affect their quality of life and health outcomes. Recent studies highlight the importance of shared decision-making (SDM) in helping patients understand their treatment options and make informed choices. SDM not only improves patient satisfaction and autonomy but also emphasizes the need for comprehensive pre-dialysis education to support optimal treatment selection.

Giant Colloidal Quantum Dot/α-GaO Heterojunction for High Performance UV-Vis-IR Broadband Photodetector.

Broadband optoelectronics, which extend from the UV to IR regions, are crucial for imaging, autonomous driving, and object recognition. In particular, photon detection efficiency relies significantly on semiconductor properties, such as absorption coefficients and electron-hole pair generation rate, which can be optimized by designing a suitable p-n junction. In this study, we devise giant PbS colloidal quantum dots (G-PbS CQDs) that exhibit high absorption coefficients and broadband absorption.
