Cancer immunotherapy of Wilms tumor: a narrative review.

Wilms tumor (WT) is the most common malignant tumor of the urinary system in children. Though the traditional treatment of surgery plus radiotherapy and chemotherapy achieves exciting clinical efficacy, in relapsed and refractory cases, the long-term overall survival rates are poor. Besides, chemotherapy and radiation have serious long-term toxic side effects on children.

Abnormal Interhemispheric Functional Connectivity in Acute Pericoronitis: A Resting-State MRI Study.

Objective: Acute pericoronitis (AP) is a prevalent cause of odontogenic toothache which can significantly impact brain function. Previous research has predominantly concentrated on localized brain activity. However, the synergistic changes between brain hemispheres induced by toothache and resulting abnormal functional connectivity across the brain have not been comprehensively studied.

A natural small molecule aspidosperma-type alkaloid, hecubine, as a new TREM2 activator for alleviating lipopolysaccharide-induced neuroinflammation in vitro and in vivo.

Neuroinflammation and oxidative stress play a crucial role in the pathogenesis of neurodegenerative diseases, including Alzheimer's disease. The triggering receptor expressed on myeloid cells 2 (TREM2), highly expressed by microglia in the central nervous system (CNS), can modulate neuroinflammatory responses. Currently, there are no approved drugs specifically targeting TREM2 for CNS diseases.

Stachydrine promotes angiogenesis by regulating the VEGFR2/MEK/ERK and mitochondrial-mediated apoptosis signaling pathways in human umbilical vein endothelial cells.

Stachydrine is a main active component of Leonurus japonicus (Chinese motherwort), which has traditionally been used to promote postpartum recovery and alleviate myocardial and cerebral ischemic injuries due to its pro-angiogenic effect. Our prior study demonstrated that stachydrine increased angiogenesis in zebrafish embryos, but its pro-angiogenic effect and underlying mechanisms on human umbilical vein endothelial cells (HUVECs) remain largely unknown. In the present study, we further investigated the role of stachydrine in sunitinib-injured HUVECs and its potential molecular mechanisms.

Development and Validation of a Deep Learning-Based Model Using Computed Tomography Imaging for Predicting Disease Severity of Coronavirus Disease 2019.

Objectives: Coronavirus disease 2019 (COVID-19) is sweeping the globe and has resulted in infections in millions of people. Patients with COVID-19 face a high fatality risk once symptoms worsen; therefore, early identification of severely ill patients can enable early intervention, prevent disease progression, and help reduce mortality. This study aims to develop an artificial intelligence-assisted tool using computed tomography (CT) imaging to predict disease severity and further estimate the risk of developing severe disease in patients suffering from COVID-19.

MicroRNA-214-3p Targeting Ctnnb1 Promotes 3T3-L1 Preadipocyte Differentiation by Interfering with the Wnt/β-Catenin Signaling Pathway.

Differentiation from preadipocytes into mature adipocytes is a complex biological process in which miRNAs play an important role. Previous studies showed that miR-214-3p facilitates adipocyte differentiation of bone marrow-derived mesenchymal stem cells (BMSCs) in vitro. The detailed function and molecular mechanism of miR-214-3p in adipocyte development is unclear.
