Function and Regulation of Age-Associated B Cells in Diseases.

The aging process often leads to immune-related diseases, including infections, tumors, and autoimmune disorders. Recently, researchers identified a special subpopulation of B cells in elderly female mice that increases with age and accumulates prematurely in mouse models of autoimmune diseases or viral infections; these B cells are known as age-related B cells (ABCs). These cells possess distinctive cell surface phenotypes and transcriptional characteristics, and the cell population is widely recognized as CD11cCD11bT-betCD21CD23 cells.

Selinexor in combination with venetoclax and decitabine in patients with refractory myelodysplastic syndrome previously exposed to hypomethylating agents: three case reports.

The management of patients with myelodysplastic syndrome (MDS) refractory to hypomethylating agents (HMAs) remains a challenge with few reliably effective treatments. Preclinical studies have shown that the inhibition of the nuclear export protein XPO1 causes nuclear accumulation of p53 and disruption of NF-κB signaling; both of which are relevant targets for MDS. Selinexor is an XPO1 inhibitor with demonstrated efficacy in MDS patients.

Silk fibroin-based hydrogels for cartilage organoids in osteoarthritis treatment.

Osteoarthritis (OA) is a common joint disease characterized by cartilage degeneration. It can cause severe pain, deformity and even amputation risk. However, existing clinical treatment methods for cartilage repair present certain deficiencies.

Standardization and consensus in the development and application of bone organoids.

Organoids, self-organized structures derived from stem cells cultured in a specific three-dimensional (3D) microenvironment, have emerged as innovative platforms that closely mimic cellular behavior, tissue architecture, and organ function. Bone organoids, a frontier in organoid research, can replicate the complex structures and functional characteristics of bone tissue. Recent advancements have led to the successful development of bone organoids, including models of callus, woven bone, cartilage, trabecular bone, and bone marrow.

Daily activities and suspected dementia among community-dwelling older adults: a cross-sectional study.

Background: Dementia is undiagnosed among many older adults, and more than half the people in local communities live with symptoms of dementia are not properly treated.

Objective: The study aims to explore the relationship between decline of daily activities and the incidence of suspected dementia.

Methods: A two-stage sampling method was used to conduct a multicenter cross-sectional survey.
