AI Article Synopsis
- Different color-formation methods and image quality influence levels of visual fatigue in the human eye, which this study measures through high-frequency components of accommodative microfluctuations and subjective questionnaires.
- 3D videos induce more visual fatigue compared to 2D videos, with shutter-type 3D displays causing more fatigue than polarized ones, and time-sharing display methods leading to greater fatigue than spatial-formation methods.
- Individuals with normal color discrimination experience higher visual fatigue than those with better color discrimination, indicating the importance of visual quality in assessing fatigue levels across different display types.
Article Abstract
Different levels of visual fatigue in the human eye depend on different color-formation methods and image quality. This paper uses the high-frequency component of the spectral power of accommodative microfluctuations as a major objective indicator for analyzing the effects of visual fatigue based on various displays, such as color-formation displays and 3D displays. Also, a questionnaire is used as a subjective indicator. The results are that 3D videos cause greater visual fatigue than 2D videos (p<0.001), the shutter-type 3D display causes visual fatigue more than the polarized type (p=0.012), the display of the time-sharing method causes greater visual fatigue than the spatial-formation method (p=0.008), and there is no significance between various light source modules of displays (p=0.162). In general, people with normal color discrimination have more visual fatigue than those with good color discrimination (p<0.001). Therefore, this paper uses the high-frequency component of accommodative microfluctuations to evaluate the physiological stress or strain by overexerting the visual system, and can compare the level of visual fatigue between various displays.

α-Cyclodextrin (αCD), a cyclic hexasaccharide composed of six glucose units, is not digested in the small intestine but is completely fermented by gut microbes. Recently, we have reported that αCD supplementation for nonathlete men improved their 10 km biking times. However, the beneficial effects of αCD on exercise are not yet fully understood.

Objective: To explore the effects of acupuncture in comparison with sham acupuncture on cognitive functions in patients with relapsing-remitting multiple sclerosis (RRMS).
Methods: In this randomized controlled trial, 31 RRMS patients in the acupuncture group were treated with traditional Chinese acupuncture based on the treatment principle of calming the mind, reinforcing qi and blood, and 31 patients in the control group were treated with sham acupuncture (shallow needling at non-acupuncture points) twice a week for 12 weeks. The primary outcome was the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) score, which was evaluated by a psychologist at baseline and after 12 weeks of treatment.

Electronic address:
Introduction: Patients with primary muscle tension dysphonia (pMTD) commonly report symptoms of vocal effort, fatigue, discomfort, odynophonia, and aberrant vocal quality (eg, vocal strain, hoarseness). However, voice symptoms most salient to pMTD have not been identified. Furthermore, how standard vocal fatigue and vocal tract discomfort indices that capture persistent symptoms-like the Vocal Fatigue Index (VFI) and Vocal Tract Discomfort Scale (VTDS)-relate to acute symptoms experienced at the time of the voice evaluation is unclear.
