miR-223 accelerates lipid droplets clearance in microglia following spinal cord injury by upregulating ABCA1.

Background: Spinal cord injury (SCI) is characterized by extensive demyelination and inflammatory responses. Facilitating the clearance of lipid droplets (LDs) within microglia contributes to creating a microenvironment that favors neural recovery and provides essential materials for subsequent remyelination. Therefore, investigating MicroRNAs (miRNAs) that regulate lipid homeostasis after SCI and elucidating their potential mechanisms in promoting LDs clearance in microglia have become focal points of SCI research.

Cellular Regulation of Macropinocytosis.

Interest in macropinocytosis has risen in recent years owing to its function in tumorigenesis, immune reaction, and viral infection. Cancer cells utilize macropinocytosis to acquire nutrients to support their uncontrolled proliferation and energy consumption. Macropinocytosis, a highly dynamic endocytic and vesicular process, is regulated by a series of cellular signaling pathways.

Current Applications of Colorectal Cancer Organoids: A Review.

Colorectal cancer is a prevalent malignancy, with advanced and metastatic forms exhibiting poor treatment outcomes and high relapse rates. To enhance patient outcomes, a comprehensive understanding of the pathophysiological processes and the development of targeted therapies are imperative. The high heterogeneity of colorectal cancer demands precise and personalized treatment strategies.

antibiotic resistance profile in Chinese children with upper gastrointestinal symptoms and a literature review for developing personalized eradicating strategies.

() infections typically occur in early childhood. Although the prevalence of in children is lower than that in adults, the eradication rate of this infection in children is relatively low because of resistance. In this study, we analyzed personalized treatment strategies to achieve treatment goals based on resistance characteristics.

[Impact of primary duodenogastric reflux and infection on gastritis and antibiotic resistance in children].

Objectives: To investigate the risk factors for (HP) infection in children with primary duodenogastric reflux (DGR) and its impact on gastritis and antibioticresistance.

Methods: A retrospective analysis was performed on the clinical data of 2 190 children who underwent upper gastrointestinal endoscopy in Wuxi Children's Hospital from January 2019 to February 2022, among whom 308 children were diagnosed with primary DGR. According to the presence or absence of HP infection, the children were classified to HP infection group (53 children) and non-HP infection group (255 children).

Dual-Carbon Phase-Encapsulated Prelithiated SiO Microrod Anode for Lithium-Ion Batteries.

Among silicon-based anode family for Li-ion battery technology, SiO, a nonstoichiometric silicon suboxide holds the potential for significant near-term commercial impact.

Promoting or inhibiting: the impact of China's urban-rural digital divide on regional environmental development.

Based on the panel data of 30 provinces in China from 2013 to 2020, this paper uses the panel fixed effect model and threshold regression method to systematically examine the impact of the urban-rural digital divide on regional environmental development from the perspective of technological innovation and human capital. The study found that the urban-rural digital divide significantly inhibited regional environmental development; however, this inhibitory effect will be substantially reduced in technological innovation and human capital adjustment. Furthermore, technological innovation and human capital have played a significant single threshold effect in the impact of the urban-rural digital divide on regional environmental development.

Alpha-1 antitrypsin inhibits fractalkine-mediated monocyte-lung endothelial cell interactions.

Chronic obstructive pulmonary disease (COPD) is characterized by nonresolving inflammation fueled by breach in the endothelial barrier and leukocyte recruitment into the airspaces. Among the ligand-receptor axes that control leukocyte recruitment, the full-length fractalkine ligand (CX3CL1)-receptor (CX3CR1) ensures homeostatic endothelial-leukocyte interactions. Cigarette smoke (CS) exposure and respiratory pathogens increase expression of endothelial sheddases, such as a-disintegrin-and-metalloproteinase-domain 17 (ADAM17, TACE), inhibited by the anti-protease α-1 antitrypsin (AAT).

Application of Methyl Jasmonate to Papaya Fruit Stored at Lower Temperature Attenuates Chilling Injury and Enhances the Antioxidant System to Maintain Quality.

Papaya fruit has a limited shelf life due to its sensitivity to decay and chilling damage during cold storage. The application of methyl jasmonate (MeJA) is known to reduce the incidence of disease and chilling injury, and to maintain the overall quality of the papaya fruit when stored at low temperature. Consequently, the effects of postharvest MeJA (1 mM) immersion on papaya fruits during low-temperature storage (10 °C ± 2 °C) for 28 days were studied.
