Purpose: To investigate the effect of red and green light beams on gait and freezing of gait (FOG) in persons with Parkinson's disease (PD).

Methods: Seven persons with PD who experienced FOG participated in the study. Gait and turning performances were studied while walking with canes with red, green, and no light beams while "off" and "on" anti-Parkinsonian medications. Gait speed, cadence, and stride were recorded. Time and number of freezing episodes were recorded during a 50-foot walk and a 360° turn.

Results: During 'off' medication, compared to no light, stride length improved when using the green light, but not the red. During the 50-foot walk, freezing episodes were reduced when using the green light compared to both the red and no light. During the 360° turn, time, number of steps and number of freezing episodes were reduced using the green light compared to the red and no light. During 'on' medication, gait speed and stride length improved more with the green light compared to the red. Neither color showed any effect on cadence during either medication state.

Conclusion: A green light improved gait and alleviate FOG in persons with PD better than a red light or no light.

The fungal green synthesis of nanoparticles (NPs) has gained great interest since it is a cost-effective and easy handling method. The process is simple because fungi secrete metabolites and proteins capable of reducing metal salts in aqueous solution, however the mechanism remains largely unknown. The aim of this study was to analyze the secretome of a Trichoderma harzianum strain during the mycobiosynthesis process of zinc and iron nanoparticles.

From the perspective of sustainable development and practical applications, there is a significant demand for the design of advanced cellulose-based film materials with superior mechanical, optical, and functional properties utilizing environmentally friendly strategies. Herein, biodegradable, mechanically robust and flame-retardant cellulose films with adjustable optical performance were successfully fabricated by in situ synthesis of NH-UiO(Zr)-66 via a DMF-free green process at room temperature. The results indicate that the introduction of NH-UiO(Zr)-66 enables films to realize a desirable flame retardancy (the limiting oxygen index (LOI) increased significantly from 19.

The integration of photothermal therapy (PTT) and gas therapy (GT) on a nanoplatform shows great potential in cancer treatment. In this paper, a tumor-targeted near-infrared/ultraviolet (NIR/UV) triggered PTT/GT synergistic therapeutic nanoplatform, PB-CD-PLL(NF)-FA, was designed based on Prussian blue (PB) nanoparticles, 5-chloro-2-nitrobenzotrifluoro (NF)-grafted polylysine (PLL(NF)), and folic acid (FA). PB serves as a core to load PLL(NF) through host-guest interaction and can further modify FA.

The first shikimic acid derived fluorescent carbon dots (SACNDs-FITC) for multi-modal detection and simultaneous removal of Hg is revealed. The fluorescence of SACNDs-FITC centered at 520 nm can be selectively quenched by Hg, while the emission centered at 420 nm remains constant which can be used for self-calibration. Naked-eye distinguishable color change from yellow to colourless under daylight and from green to blue under UV light could be observed for SACNDs-FITC in the real-time detection of Hg.

Background: Cellular vacuolization is a commonly observed phenomenon under physiological and pathological conditions. However, the mechanisms underlying vacuole formation remain largely unresolved.

Methods: LysoTracker Deep Red probes and Enhanced Green Fluorescent Protein-tagged light chain 3B (LC3B) plasmids were employed to differentiate the types of massive vacuoles.
