Abstract
Objective Acupuncture has certain effects to improve myopia visual function, but its neural mechanism is unclear. In this study, we acupunctured at the right Taiyang acupoint of myopic patients to analyze the effects of acupuncture on visual function and electroencephalographic activity and to investigate the correlation between improvements in visual function and changes in the brain. Methods In this study, a total of 21 myopic patients were recruited. The contrast sensitivity (CS) of the subjects was examined before and after acupuncture, and electroencephalography (EEG) data of the entire acupuncture process were recorded. Results The study found that compared with before acupuncture, the CS of both eyes in myopic patients at each spatial frequency was increased after acupuncture; compared with the resting state, the contribution of microstate C was decreased during the post-acupuncture state, and the transition probability between microstate A and microstate C was reduced; in addition, the contribution of microstate C was negatively correlated with CS at both 12 and 18 cpd. Conclusion The contrast sensitivity of myopic patients was improved after acupuncture at the Taiyang acupoint (20 min), which may be related to microstate C.

Food Res Int 2023; 172:113213. [PMID: 37689958 DOI: 10.1016/j.foodres.2023.113213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 06/28/2023] [Accepted: 06/29/2023] [Indexed: 09/11/2023]
Abstract
Yellow oil mud crab (YOC) is a new variant of mud crab (Scylla paramamosain), which was attracted much attention in recent years due to its high level of nutrition. However, the nutritive values and the physiological changes in YOC have not been clearly understood. In this study, we aimed to identify the nutrient compositions (including total carotenoid content (TCC), total lipid content (TLC), total antioxidant capacity (TAC), and fatty acids) and differences in genes related to the biosynthesis of fatty acids using transcriptome analysis in YOC in comparison with those of normal mud crabs. As a result, observations on the morphological characteristics showed that the YOC exhibits a difference in the color of the muscle, gills (orange-yellow), and hemolymph (yellow) compared with the normal female crabs (NFC) (blue or nattier blue). The TCC and TLC (84.96 ± 9.65 μg/g in muscle and 1.39 ± 0.10 μg/mL in hemolymph) or TAC (1.52 ± 0.17 mM in hemolymph) of YOC were higher than that of NFC and normal male crab (NMC). YOC had lower saturated fatty acids, but higher unsaturated fatty acids, as well as the ratio of n-3/n-6 of fatty acids in muscle and hemolymph, compared with those of NFC and NMC. Furthermore, the transcriptome profile revealed that the unigenes in YOC were enriched in the synthesis of n-3 fatty acids. Furthermore, more unigenes related to 'Biosynthesis of unsaturated fatty acids' were identified in muscle and hemocytes, while fewer were in the gonads of YOC. Additionally, the positive (in muscle and hemocytes) and a negative correlation (in gonads) between expressions of unigenes and contents of TLC, TCC, and UFA were found, indicating a better synthesis ability of fatty acids in the muscle and hemocytes of YOC. Overall, compared to NFC and NMC, YOC has higher nutrients and is a better food nutrient source for humans.

Carotenoids from Starfish Patiria pectinifera: Therapeutic Activity in Models of Inflammatory Diseases. Mar Drugs 2023; 21:470. [PMID: 37755083 PMCID: PMC10533026 DOI: 10.3390/md21090470] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Revised: 08/20/2023] [Accepted: 08/25/2023] [Indexed: 09/28/2023] Open
Abstract
The carotenoids mixture (MC) isolated from the starfish Patiria. pectinifera contains more than 50% astaxanthin, 4-6% each zeaxanthine and lutein, and less pharmacologically active components such as free fatty acids and their glycerides. Astaxanthin, the major component of MC, belongs to the xanthophyll class of carotenoids, and is well known for its antioxidant properties. In this work, in vitro and in vivo studies on the biological activity of MC were carried out. The complex was shown to exhibit anti-inflammatory, anti-allergic and cancer-preventive activity, without any toxicity at a dose of 500 mg/kg. MC effectively improves the clinical picture of the disease progressing, as well as normalizing the cytokine profile and the antioxidant defense system in the in vivo animal models of inflammatory diseases, namely: skin carcinogenesis, allergic contact dermatitis (ACD) and systemic inflammation (SI). In the skin carcinogenesis induced by 7,12-dimethylbenzanthracene, the incidence of papillomas was decreased 1.5 times; 1% MC ointment form in allergic contact dermatitis showed an 80% reduced severity of pathomorphological skin manifestations. Obtained results show that MC from starfish P. pectinifera is an effective remedy for the treatment and prevention of inflammatory processes.

Abstract
Retinal ganglion cells (RGCs) are the sole output neurons conveying visual stimuli from the retina to the brain, and dysfunction or loss of RGCs is the primary determinant of visual loss in traumatic and degenerative ocular conditions. Currently, there is a lack of RGC-specific Cre mouse lines that serve as invaluable tools for manipulating genes in RGCs and studying the genetic basis of RGC diseases. The RNA-binding protein with multiple splicing (RBPMS) is identified as the specific marker of all RGCs. Here, we report the generation and characterization of a knock-in mouse line in which a P2A-CreERT2 coding sequence is fused in-frame to the C-terminus of endogenous RBPMS, allowing for the co-expression of RBPMS and CreERT2. The inducible Rbpms-CreERT2 mice exhibited a high recombination efficiency in activating the expression of the tdTomato reporter gene in nearly all adult RGCs as well as in differentiated RGCs starting at E13.5. Additionally, both heterozygous and homozygous Rbpms-CreERT2 knock-in mice showed no detectable defect in the retinal structure, visual function, and transcriptome. Together, these results demonstrated that the Rbpms-CreERT2 knock-in mouse can serve as a powerful and highly desired genetic tool for lineage tracing, genetic manipulation, retinal physiology study, and ocular disease modeling in RGCs.

Abstract
Clinical trials typically analyze multiple endpoints for signals of efficacy. To improve signal detection for treatment effects using the high-dimensional data collected in trials, we developed a hierarchical Bayesian joint model (HBJM) to compute a five-dimensional collective endpoint (CE5D) of contrast sensitivity function (CSF) and visual acuity (VA). The HBJM analyzes row-by-row CSF and VA data across multiple conditions, and describes visual functions across a hierarchy of population, individuals, and tests. It generates joint posterior distributions of CE5D that combines CSF (peak gain, peak frequency, and bandwidth) and VA (threshold and range) parameters. The HBJM was applied to an existing dataset of 14 eyes, each tested with the quantitative VA and quantitative CSF procedures in four Bangerter foil conditions. The HBJM recovered strong correlations among CE5D components at all levels. With 15 qVA and 25 qCSF rows, it reduced the variance of the estimated components by 72% on average. Combining signals from VA and CSF and reducing noises, CE5D exhibited significantly higher sensitivity and accuracy in discriminating performance differences between foil conditions at both the group and test levels than the original tests. The HBJM extracts valuable information about covariance of CSF and VA parameters, improves precision of the estimated parameters, and increases the statistical power in detecting vision changes. By combining signals and reducing noise from multiple tests for detecting vision changes, the HBJM framework exhibits potential to increase statistical power for combining multi-modality data in ophthalmic trials.

Abstract
BACKGROUND Glaucoma is a progressive, sight-threatening disease. In this study, we aimed to compare macular pigment optical density measurements of the primary open-angle glaucoma (POAG) patients under topical therapy with the control group. METHODS This cross-sectional study included 55 eyes of 30 POAG patients and 42 eyes of 22 age- and sex-matched healthy controls. The data of all participants were analyzed retrospectively. Subsequently, patients with POAG were divided into two groups: Group 1 received therapy including prostaglandin analogue (PGA), and group 2 was using anti-glaucomatous drugs other than PGA. All participants underwent detailed ophthalmologic examination, including fundus photography and spectral-domain optical coherence tomography. In addition, macular pigment optical density (MPOD) was measured using the Zeiss Visucam 500 fundus camera. Mann-Whitney U test, Independent samples t-test, and one-way multivariate analysis of variance (MANOVA) tests were used to compare the values between and among groups. RESULTS There was no significant difference in age and sex between POAG and healthy controls (p=0.229, p=0.376, respectively). All MPOD values were higher in the glaucoma group than in the control group. MPOD max, MPOD volume, and MPOD area were significantly higher in the POAG group than in the control group (p<0.05 for all). However, there was no significant difference in the mean MPOD (p=0.083). In addition, in pairwise comparisons, the PGA therapy group had significantly higher MPOD values than the control group (p<0.05 for all). CONCLUSION MPOD levels increased in patients receiving PGA treatment. In addition, retinal nerve fiber layer thickness was positively correlated with MPOD levels in POAG patients. Therefore, PGAs may have a neuroprotective effect.

Abstract
SYNOPSIS/PRECIS We investigated the relationship between contrast sensitivity (CS) and vision-related quality of life (VR-QOL) in patients with central retinal vein occlusion following ranibizumab intravitreal injection; CS showed a stronger association with VR-QOL than visual acuity. BACKGROUND/AIMS To investigate the relationship between CS, VR-QOL and optical coherence tomography (OCT) findings in patients with cystoid macular oedema secondary to central retinal vein occlusion (CRVO-CMO) following intravitreal injection of ranibizumab. METHODS This was a multicentre, open-label, single-arm, prospective study. The study included 23 patients with CRVO-CMO who were followed up for 12 months after treatment. The best-corrected visual acuity (BCVA), letter contrast sensitivity (LCS) and OCT images were obtained every month. For VR-QOL assessment, the 25-item National Eye Institute Visual Function Questionnaire (VFQ-25) was administered to the patients before treatment and at 3, 6 and 12 months following treatment. RESULTS The LCS and VFQ-25 composite score improved significantly from baseline to 12 months following treatment. The multiple regression analysis revealed that the LCS of the affected eye and BCVA of the fellow eye were related to the VFQ-25 composite score following treatment. The LCS improvement showed a significant correlation with the improvement in the VFQ-25 composite score, whereas the BCVA improvement was not correlated with the improvement in the VFQ-25 composite score. Stepwise multiple regression analyses revealed that, at the time of macular oedema resolution, the distance between the external limiting membrane and retinal pigment epithelium (ELM-RPE) and average ganglion cell-inner plexiform layer (GCIPL) thickness were associated with LCS. CONCLUSION CS had a stronger association with VR-QOL than with BCVA in patients with CRVO-CMO. With the resolution of macular oedema, CS was associated with ELM-RPE thickness and average GCIPL thickness.

Abstract
PURPOSE Atropine at a low concentration is considered a safe and effective treatment to mitigate myopia progression. However, the potential unwanted side effects of administering atropine at a low dose on visual functions other than best corrected visual acuity has not been investigated. In this study, we investigate the short-term (12,16, and 20 h) and long-term (1, 2, and 4 weeks) effects of 0.01% atropine (i.e., 0.1 mg/ml) on contrast sensitivity (CS) in patients with myopia. METHODS Thirty adults (23.33 ± 2.93 years old) with myopia between -1.00 and -6.00 diopters (D), astigmatism of -1.50 D or less, and anisometropia of 1.00 D or less, participated in this prospective, masked, placebo-controlled, randomized study. The participants were randomly assigned to receive 0.01% atropine or polyvinyl alcohol eye drops once nightly to both eyes for four weeks. CS was measured binocularly at baseline and 12, 16, 20 h, 1, 2, and 4 weeks after the first use of the eye drops. RESULTS There was no statistically significant differences of CS found between atropine and placebo-controlled groups in both short-term and long-term. There was no statistically significant interaction effect found between the time and group. CONCLUSION We demonstrated no significant deleterious effect of 0.01% atropine on adult myopes' CS.

Abstract
Purpose: To assess visual results, macular modifications, and the incidence of clinically significant macular edema (CSME) in patients using a topical triamcinolone acetonide-loaded liposomal formulation (TA-LF) after femtosecond laser-assisted cataract surgery (FLACS). Methods: Fifty-six eyes after FLACS were selected. Twenty-eight eyes in the combined therapy group (P + N) were treated with prednisolone 1% and nepafenac 0.1% for 21 days postoperatively, whereas 28 eyes in the TA-LF group received a liposomal formulation containing 2 mg/mL of TA (0.2%) for the same period of time. Follow-up visits at 1 day, 6 weeks, and 12 weeks after surgery consisted of visual acuity, contrast sensitivity (CS), central foveal thickness (CFT), total macular volume (TMV) measurements, and the detection of CSME. Results: CS improved in the TA-LF group (basal value: 1.087 ± 0.339 vs. 1.276 ± 0.147 at week 12, P = 0.0346), whereas in the P + N group, CS was not different from the baseline (basal value: 1.130 ± 0.331 vs. 1.274 ± 0.133 at week 12, P = 0.1276). There were similar increases in postoperative CFT and TMV in both groups. CFT and TMV significantly correlate with CS only in the TA-LF group. The r2 for CFT and CS was 0.1963 (P = 0.0206), whereas the r2 for TMV and CS was 0.3615 (P = 0.0007) at 12 weeks. No difference was observed in the incidence of CSME between the groups. Conclusion: TA-LF is associated with better CS outcomes compared to combined therapy after FLACS.
