AI Article Synopsis
- * Twelve patients received LEDT twice a week for four weeks, and results showed significant improvements in their pain and stiffness scores, as well as a noticeable increase in type III collagen levels in tendon cells, suggesting a positive biological response.
- * Although tendon thickness decreased slightly by week 8, this change wasn't statistically significant, and there were no reported adverse effects, indicating LEDT could be a promising non-drug treatment alternative.
Article Abstract
Objective: The objective of this study was to evaluate the safety and efficacy of light-emitting diode therapy (LEDT) in the management of pain and stiffness in patients with refractory hand tenosynovitis to non-steroidal anti-inflammatory drugs.
Methods: A total of 12 patients were enrolled in the study and received LEDT twice a week for four weeks. Sociodemographic, clinical, and laboratory data were collected, and the visual analog scale (VAS) pain and stiffness scores of each hand were assessed every two weeks. The thickness of the flexor tendon in the patients' hand was evaluated using ultrasonography. To investigate the molecular effects of LEDT, we measured the expression levels of type III collagen in tendon cells, with and without LEDT treatment.
Results: After undergoing LEDT, participants showed clinically significant improvements in VAS pain scores at weeks 2, 4, and 8 compared to their baseline, and in VAS stiffness scores at weeks 4 and 8. According to the ultrasonography results, there was a decreasing tendency in tendon thickness for each finger in week 8 compared to the baseline, but the difference was not statistically significant. No adverse events were reported. Additionally, our results indicated a significant increase in type III collagen levels in the LEDT group compared to the control group (1.48±0.18 vs. 0.99±0.02, p=0.031), indicating a potential molecular mechanism for the observed clinical improvements.
Conclusion: LEDT may provide a viable alternative to pharmacological treatments in the future, due to its simple and easy method of administration.

Light-emitting diode (LED) lamps are efficient elicitors of secondary metabolites. To investigate the influence of LED light on steviol glycosides (SGs) and phenolic compounds biosynthesis, stevia shoots were cultured under the following LED lights: white-WL, blue-B, red-R, 70% red and 30% blue-RB, 50% UV, 35% red and 15% blue-RBUV, 50% green, 35% red and 15% blue-RBG, 50% yellow, 35% red and 15% blue-RBY, 50% far-red, 35% red and 15% blue-RBFR and white fluorescent light (WFl, control). RBG light stimulated shoots' biomass production.

Due to intrinsic defects in blue-light-emitting perovskite materials, the charge carriers are prone to being trapped by the trap states. Therefore, the preparation of efficient blue-light-emitting perovskite materials remains a significant challenge. Herein, CsPb(Cl/Br) nanocrystal (NCs)@SiO structures were fabricated through hydrolyzing (3-aminopropyl)-triethoxysilane (APTS).

The pupillary direct and consensual reflex is an important non-invasive quick assessment of the neurological state of the eye. Currently, there is no cheap and affordable recording tool for screening and documentation of a relative afferent pupillary defect. We describe how to construct a frugal, do-it-yourself handheld scotopic binocular pupillometer device called Pupilmate.

Direct harvesting of abundant solar thermal energy within organic phase-change materials (PCMs) has emerged as a promising way to overcome the intermittency of renewable solar energy and pursue high-efficiency heating-related applications. Organic PCMs, however, generally suffer from several common shortcomings including melting-induced leakage, poor solar absorption, and low thermal conductivity. Compounding organic PCMs with single-component carbon materials faces the difficulty in achieving optimized comprehensive performance enhancement.
