Cross-reactivity of anti-modified protein antibodies in rheumatoid arthritis.

This review comprehensively discusses the cross-reactivity of autoantibodies against modified proteins (AMPAs), the hallmark of rheumatoid arthritis (RA). We found that regardless of tissue sources, subtypes, or isotypes of B cells, AMPAs show high cross-reactivity within and across antigens undergoing citrullination, carbamylation, lysine-acetylation or ornithine-acetylation. The cross-reactive patterns of AMPAs display clonal and individual heterogeneity.

Recent Progress in Balancing the Activity, Durability, and Low Ir Content for Ir-Based Oxygen Evolution Reaction Electrocatalysts in Acidic Media.

Proton exchange membrane (PEM) electrolysis faces challenges associated with high overpotential and acidic environments, which pose significant hurdles in developing highly active and durable electrocatalysts for the oxygen evolution reaction (OER). Ir-based nanomaterials are considered promising OER catalysts for PEM due to their favorable intrinsic activity and stability under acidic conditions. However, their high cost and limited availability pose significant limitations.

Safety and Efficacy of a Novel Hemostatic Powder in Total Knee Arthroplasty.

This retrospective study evaluated the safety and efficacy of SURGICEL® Powder-Absorbable Hemostatic Powder (SP) made from oxidized regenerated cellulose (ORC) in total knee arthroplasty (TKA). Ninety-one patients who underwent TKA at Peking University Third Hospital between January 2024 and July 2024 were retrospectively analyzed. Hemostatic effectiveness was evaluated by comparing perioperative blood loss, hemoglobin (Hb) levels, hematocrit (HCT), and transfusion rates.

-driven CX3CR1 PD-L1 phagocytes route to tumor tissues and reshape tumor microenvironment.

The intracellular bacterium (Fn) mediates tumorigenesis and progression in colorectal cancer (CRC). However, the origin of intratumoral Fn and the role of Fn-infected immunocytes in the tumor microenvironment remain unclear. Here, we observed that Fn-infected neutrophils/macrophages (PMNs/MΦs), especially PMNs, accumulate in tumor tissues and fecal Fn abundance correlates positively with an abundance of blood PD-L1 PMNs in CRC patients.

[Analysis on the status quo of awareness of knowledge about hepatitis C prevention and treatment and its influencing factors among people aged 15-65 years in Henan Province, 2021].

From June to September 2021, residents aged 15-65 years from 18 provincial cities and 10 directly administered counties (cities) in Henan Province were collected for a questionnaire survey, so as to understand the status quo of the knowledge and related influencing factors of hepatitis C prevention and treatment. Among 11 627 subjects, the adjusted awareness rate of knowledge about hepatitis C prevention and treatment was 59.2% (95%: 58.
