Mechanism of Hydrogen Sulfide Generation and Prevention Strategies in Oil and Gas Fields: A Case Study of the Sickle Bay Operation Area

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To address the persistent exceedance of hydrogen sulfide (H2S) concentrations and the limited effectiveness of existing treatments in the Sickle Bay oil production area, this study deeply analyzes the mechanism of H2S generation in the Sickle Bay oil production area and proposes targeted prevention and control strategies. The results show that

Inosine triphosphate pyrophosphatase activity as a potential predictor of methotrexate remission in juvenile idiopathic arthritis

Arthritis &Rheumatology, Accepted Article.
Background Methotrexate (MTX) is the first‐line therapy for juvenile idiopathic arthritis (JIA), but up to 40% of patients don't respond. Low inosine‐triphosphate‐pyrophosphatase (ITPA) activity has been associated with reduced clinical remission. We investigated ITPA role and the underlying mechanisms in vitro.

Tissue‐specific and spatially dependent metabolic signatures perturbed by injury in male and female mice

Arthritis &Rheumatology, Accepted Article.
Objective Osteoarthritis—the leading cause of disability worldwide—disproportionately affects females, yet sex remains an overlooked determinant. This disparity stems from sex‐specific differences in injury susceptibility—a major risk factor for disease.

Aromatic Diester Anolytes for Nonaqueous Redox Flow Batteries

Batteries &Supercaps, EarlyView.
Owing to their extended π‐conjugation 2,2′‐bipyridyl aromatic diesters are stable in singly‐ and doubly‐reduced states. In a redox flow battery a high battery voltage of 2.82 V can be realized and a capacity a capacity retention of 99.5% per cycle for 260 cycles.
