Sleep Matters: Exploring the Link Between Sleep Disturbances and Fatigue in Rheumatoid Arthritis

open access: yesArthritis Care &Research, EarlyView.
Objective Fatigue is a prevalent and debilitating symptom for patients with rheumatoid arthritis (RA). Although patients and rheumatologists often attribute fatigue to inflammation, other factors such as sleep disturbances are frequently overlooked. This study aims to explore the relationship between subjective (self‐reported) and objective (actigraphy

Effectiveness of Chemical and Thermal Treatments on Control Rhizopus stolonifer Fruit Infection Comparing Tomato Cultivars with Different Sensitivities to Cracking [PDF]

open access: yes, 2019
Tomatoes are among the most important horticultural crops; however, it is estimated that 30% of tomato yield is lost due to postharvest rot due to Rhizopus stolonifer, a fungus which requires lesions to initiate the infectious process.

The Regulation of Trace Metal Elements in Cancer Ferroptosis

open access: yesAdvanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.
