Spatiotemporal Evolution and Quantitative Attribution of NDVI in the Lesser Khingan Mountains Considering Lag–Cumulative Effects

Boreal forest ecosystems across mid-to-high latitudes in the Northern Hemisphere show strong responses to climate change. Vegetation growth is influenced by cumulative climatic effects with time lags, as well as human disturbances. This study selects the Lesser Khingan Mountains...

Evaluating the Resilience of Cold-Region Rice Varieties to Climate Variability and Change Using the BDH-Rice Model: A Case Study in the Sanjiang Plain

The Sanjiang Plain is a key cold-region rice production area in Northeast China, where climate variability and warming may alter the adaptability and yield stability of rice varieties. Identifying varieties with both high yield potential and stable performance under current and f...

Natural Polysaccharides for Rheumatoid Arthritis Therapy: Mechanism, Drug Delivery and Clinical Application

ABSTRACT Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized primarily by chronic synovitis. Clinically, RA manifests as joint pain, swelling, and functional impairment caused by persistent synovial inflammation. Additionally, RA can involve vital organs, inc...

Spatiotemporal Patterns and Fine-Scale Natural Capital Accounting for Land Resources in Heilongjiang Province, China

Global land degradation and the imbalance between human demand and land resource supply have become prominent challenges to regional ecological security. The compilation of a land resource balance sheet is helpful for the construction of an ecological civilization and the governa...
