Methods: In this study, 24-month-old (aged) mice were used as a naturally occurring model of aging-associated sarcopenia, while 2-month-old (young) mice served as the normal control. Six weeks of treadmill training was employed as an aerobic exercise intervention. The mRNA and protein levels of fibronectin type III domain-containing protein 5 (Fndc5/irisin), MuRF1, and Atrogin-1 in gastrocnemius muscles were analyzed using qRT-PCR and Western blot.

Currently, high-purity CO gas has been widely used as the feedstock for most of the CORR studies, while CO sources with a typically low concentration impose the extra cost for CO capture and purification steps. The direct utilization of low-concentration CO for the CORR is a promising approach to substantially address this problem.

The purpose of this study was to determine whether abdominal aortic calcification (AAC) may have an impact on PD patients' cognitive function.
Methods: In this cross-sectional study of 110 PD patients, cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), and AAC severity was quantified via lateral lumbar radiography (Kauppila method).
Objective: The present research aims to explore the relationship between coping style, teacher-student relationship, and sports anxiety among middle school students.
Methods: A total of 289 Chinese middle school students from three schools in Shanghai participated in the survey.
Results: (1) A negative teacher-student relationship significantly affects sports anxiety, and conversely, sports anxiety significantly impacts the negative teacher-student relationship, demonstrating a strong mutual effect; (2) Both active coping style and negative coping style significantly influence sports anxiety, while sports anxiety also significantly affects active coping style among middle school students.
Purpose: Kawasaki disease (KD) is an acute febrile vasculitis and the leading cause of acquired heart disease in children. However, early diagnosis of KD remains challenging, and its pathogenic mechanisms are yet to be fully elucidated. This study utilized Olink Targeted Proteomics to analyze serum protein profiles and identify potential early diagnostic biomarkers for patients with KD.

While current treatments focus on symptom management or surgical intervention, tissue engineering using IVD-derived cells, biofactors, and scaffolds offers a promising regenerative approach. Here, human NP cells (NPCs) and annulus fibrosus cells (AFCs) are immortalized with human telomerase reverse transcriptase (hTERT), generating immortalized NPCs (iHNPCs) and AFCs (iHAFCs).

However, effectively isolating and sensitively detecting EVs with convenience still face challenges. Herein, we propose a highly sensitive and specific platform for EV detection by integrating a metal-organic framework (MOF)-based DNA biobarcodes strategy with a rolling circle amplification (RCA)/G-quadruplex system.

The reduction of the linker symmetry arises from both the asymmetric pyrrolo-pyrrole core and the integration of both the - and -benzoate coordination groups on the linkers. Both MOFs are composed of 8-connected Zr nodes and 4-connected highly deformed TAPP linkers with the same topology, but distinct linker arrangements can be observed in two structures.

Here, a typical period marked by the easing of the "zero-COVID" policy in December 2022, resulting in unprecedented infections in China, was chosen to illustrate the environmental impact of pharmaceutical usage during the COVID-19 pandemic. A suspect screening workflow was developed to identify pharmaceuticals and transformation products (TPs) in wastewater influent and effluent from a wastewater treatment plant (WWTP) during the peak and postpeak periods of COVID-19, integrating medication recommendations and TPs' prediction.

In the intensive care unit (ICU), the unique environment can exacerbate disruptions in SCR. Few studies have identified the characteristics of SCR in the ICU, and the roles of patient characteristics, illness and medical interventions in ICU SCR remain unclear.

With growing concerns about information security, protecting the privacy of user-sensitive data has become crucial. The rapid development of multi-modal retrieval technologies poses new threats, making sensitive data more vulnerable to leakage and malicious mining. To address this, we introduce a Proactive Adversarial Multi-modal Learning (PAML) approach that transforms sensitive data into adversarial counterparts, evading malicious multi-modal retrieval and ensuring privacy.

This study investigates the role of circALPK2, a circular RNA derived from the back-splicing of the 4th exon of alpha protein kinase 2 (ALPK2), in regulating cardiomyocyte proliferation and its therapeutic efficacy in myocardial infarction (MI) treatment.
Methods: Human embryonic stem cell-derived cardiomyocytes (hESC-CMs) were used to assess the expression and function ofcircALPK2.
Ethnopharmacological Relevance: Although several traditional Chinese medicine formulas have demonstrated remarkable outcomes in suppressing the severe gastrointestinal toxicity induced by irinotecan (CPT-11), few studies have investigated whether enhanced anti-cancer efficacy and reduced intestinal toxicity can be achieved through co-administration. CPT-11, as a first-line drug for treating colorectal cancer, has the side effect of intestinal toxicity. Previous studies have primarily focused on using traditional Chinese medicine to alleviate diarrhea caused by CPT-11.

The complexity of MASLD, including crosstalk between multiple organs and the liver, makes developing a new drug for MASLD challenging, especially in single-drug therapy. It was reported that upregulation of Notch1 is closely associated with the function of pro-inflammatory macrophages.
