Background: Pediatric patients undergoing surgery frequently experience significant anxiety, which can result in adverse effects such as prolonged sedation and behavioral changes associated with pharmacological interventions such as oral midazolam. Video games offer a nonpharmacological distraction method that shows promise in alleviating procedural anxiety without significant adverse effects. However, the effectiveness of video games compared to midazolam in managing perioperative anxiety remains uncertain.

Endocrine-disrupting chemicals (EDCs) are ubiquitous emerging environmental contaminants. However, the comprehensive impact of EDCs on soil ecosystems, particularly on the model organism Eisenia fetida, remains inadequately understood due to disparate experimental and assessment methods. A meta-analysis was conducted to analyze the effects of EDCs on earthworm functional traits, including survival, behavior, growth, reproduction, and cellular responses.

Vegetation resilience, characterized by the ability of vegetation to maintain stable states, is considered fundamental to ecosystems' structural and functional stability. Under the background of vegetation ecosystems being increasingly endangered by numerous disturbances, determining the nonlinear changing trend of the recovery rate of vegetation to external disturbances and its response to various forces is paramount. Herein, we quantified the global vegetation resilience and its regime shifts by measuring the lag-1 autocorrelation to the interannual kernel Normalized Difference Vegetation Index (kNDVI) from 1982 to 2020, clarified the contribution rates of driving forces on vegetation resilience variation by partial correlation analysis.

Although the combination of radiotherapy and immunotherapy is regarded as a promising clinical treatment strategy, numerous clinical trials have failed to demonstrate synergistic effects. One of the key reasons is that conventional radiotherapies inevitably damage intratumoral effector immune cells. Boron Neutron Capture Therapy (BNCT) is a precise radiotherapy that selectively kills tumor cells while sparing adjacent normal cells, by utilizing B agents and neutron irradiation.

Gosling gout is usually considered to be caused by goose astrovirus 2 (GoAstV-2); however, goose astrovirus 3 (GoAstV-3) has also been shown to play a pathogenic role in this disease. Here, we developed new assays for specific detection of goose astroviruses, including GoAstV-2- and GoAstV-3-specific reverse transcription (RT)-PCR and real-time fluorescence quantitative PCR (RT-qPCR) assays. These assays revealed coinfection with GoAstV-2 and GoAstV-3 in 19 (57.

The intricate physiological microenvironment of the diabetic wound characterized by overexpressed reactive oxygen species (ROS), persistent inflammation, angiogenetic dysfunction, and bacterial infection impeded the healing process. Herein, a photo-crosslinking composite hydrogel was fabricated based on the methacrylate modification of sesbania gum (SG) and γ-polyglutamic acid (γ-PGA), which could trigger free radical polymerization to form interpenetrating polymer network under 365 nm UV. Meanwhile, the micronized traditional Chinese medicine Huoxue Tongluo extract (HXTL) was encapsulated into the hydrogel to prepare the wound dressing (H-SGPGA).

Purpose: Emergence agitation (EA) after (adeno)tonsillectomy (AT) surgery impairs recovery in children. Adequate analgesia plays a crucial role in reducing EA incidence. This study investigated whether hydromorphone infusion (30 μg/kg) during anesthesia induction could reduce EA following AT surgery for obstructive sleep apnea in children.

Background And Aims: Endoscopic surgery (ES) and small bone window craniotomy (SBWC) are commonly used methods for hematoma removal in cases of intracerebral hemorrhage (ICH). However, their long-term efficacy and safety remain uncertain.

Methods: A systematic search was performed in the PubMed, Embase, and Cochrane Library databases from inception to June 30, 2024.

Depression, a prevalent psychiatric disorder of ambiguous etiology and high heterogeneity, has been recently linked to the primary visual cortex (V1). However, the precise circuits mediating the impact of V1 on depressive-like behaviors are poorly understood. Here, we demonstrate that the V1, specifically the lateral posterior nucleus of the thalamus (LP)-projecting V1 glutamatergic subpopulation (Glu neurons), shows reduced activity after chronic restraint stress (CRS) in male mice, leading to depressive-like behaviors.

The sodium pump Na+/K+-ATPase (NKA), an enzyme ubiquitously expressed in various tissues and cells, is a critical player in maintaining cellular ion homeostasis. Dysregulation of α1 subunit of NKA (NKAα1) has been associated with cardiovascular and metabolic disorders, yet the exact role of NKAα1 in diabetes-induced endothelial malfunction remains incompletely understood. The NKAα1 expression and NKA activity were examined in high-glucose (HG)-exposed endothelial cells (ECs) and mouse aortae, as well as in high-fat-diet (HFD)-fed mice.

The pursuit of efficient and stable urea oxidation reaction (UOR) electrocatalysts is paramount for the sustainable utilization of renewable energy sources and the treatment of wastewater with urea content. This research introduces the successful fabrication of (FeNi)S/CoS/NF mesh heterojunction materials, which are replete with interfaces that facilitate enhanced catalytic activity. Benefiting from the electron transfer behavior from (FeNi)S to CoS, and the promotion of surface adsorption of SO , the (FeNi)S/CoS/NF electrocatalyst has excellent UOR catalytic performance.

To address challenges such as limited loading capacity, restricted targeting precision, and low yield of natural exosomes as drug carriers, the fusion of liposomes and exosomes to create hybrid vesicles has emerged as a viable solution approach. While current research mainly focuses on designing functionalized liposomes, less attention is given to how liposome membrane materials affect the elasticity of these hybrids and their delivery efficiency. This study utilized milk exosomes (mExos) as model exosomes, and generated hybrid vesicles with varying elasticity through the fusion of phospholipids with differing chain lengths, examining the disparities among various hybrid vesicles in their ability to overcoming the gastrointestinal barriers.

Immunometabolic variations in macrophages critically influence their differentiation into pro-inflammatory or anti-inflammatory phenotypes, thereby contributing to immune homeostasis, defense against infection, and tissue repair. Dysregulation of macrophage immunometabolism has been closely implicated in several metabolic diseases, including obesity, type 2 diabetes mellitus (T2DM), non-alcoholic fatty liver disease (NAFLD), hypertension, atherosclerosis, and gout, which positions macrophages as potential therapeutic targets. Recently, several natural products that target macrophage metabolic pathways have shown significant efficacy in managing metabolic diseases; however, a systematic review of these findings has yet to be conducted.

Myocardial fibrosis (MF) is a common pathological manifestation of many cardiovascular diseases, such as myocardial infarction, myocardial ischemia, and sudden cardiac death. It is characterized by excessive proliferation and activation of fibroblasts, transformation into myofibroblasts, and, eventually, excessive deposition of the extracellular matrix, resulting in heart damage. Currently, modern drugs such as angiotensin-converting enzyme inhibitors, diuretics, and β-blockers can improve myocardial fibrosis in clinical treatment, but their therapeutic effect on this disease is limited, with obvious side effects and high cost.

Tomato (Solanum lycopersicum) is an important crop but frequently experiences saline-alkali stress. Our previous studies have shown that exogenous spermidine (Spd) could significantly enhance the saline-alkali resistance of tomato seedlings, in which a high concentration of Spd and jasmonic acid (JA) exerted important roles. However, the mechanism of Spd and JA accumulation remains unclear.
