Objective To investigate the causes and treatment of delayed corneal epithelial healing after trans-epithelial photorefractive keratectomy (TPRK). Methods A case of a young female with delayed corneal epithelial healing after TPRK for myopia was retrospectively analyzed. Results Delayed corneal healing is a rare complication in the early stage after TPRK. In this case, it caused symptoms such as pain, blurred vision, glare and tearing. Long-term wearing of contact lenses, meibomian gland dysfunction and postoperative use of drugs that inhibited epithelial growth were risk factors for this patient. After comprehensive treatment with bandage soft contact lenses, sodium hyaluronate, deproteinized calf blood extractive, glucocorticoids, ganciclovir ophthalmic gel and corneal epithelial debridement, corneal epithelium healed completely, but haze grade 1 was present in the delayed healing area on 22nd postoperative day. After follow-up treatment, haze disappeared and cornea returned transparent half a year later. Conclusions Patients with risk factors for delayed corneal epithelial healing after TPRK should undergo a comprehensive preoperative examination. Delayed corneal epithelial healing should be treated early and comprehensively, while alerting to haze and herpes simplex virus infection.

Objective: On 6 March 2018, the Cleveland Cavaliers power forward Kevin Love penned an op-ed for "The Players' Tribune." In big, bold letters, the title, 'Everyone Is Going Through Something' gave way to his proclamation of personal mental health struggles. This study assessed the impact of Love's personal mental health testimony on the audience. Design: Content analysis of Instagram user's responses to Love's 2018 announcement of panic disorder. Setting: Data were collected on 19 June 2018. Comments on Love's post were manually copied into an Excel spreadsheet. Due to Instagram's 'top comments' and 'newest first' algorithms that determine both the visibility and order of user responses, not all comments were accessible for analysis. A total of 1,234 comments served as the sample. Method: Two trained coders analysed the comments for exhibitions of audience involvement with Love, emotional responses and perceptions of social biases surrounding mental illness. Results: Social media users who expressed hope were more likely to share their own mental health experiences. In addition, users who expressed hope were significantly more likely to mention wanting to reduce social bias surrounding discussion of mental health than posts without hope. Conclusion: Building on previous work that determined social media users can respond to a celebrity's physical health testimonial with positive, future-oriented emotions, this study established that the same response can exist when analysing a celebrity's mental health testimonial.

Abstract Background Exploration of adaptive evolution of organisms in response to environmental change can help to understand the evolutionary history of species and the underlying mechanisms of adaptation to local environments, thus guiding future conservation programmes. Before the introduction of Apis mellifera in China, eastern honey bees (Apis cerana) were the only species used for beekeeping in this region. In the mountains of Changbai, populations of A. cerana are considered a distinct ecotype of the species which formed through the distinct selective pressures in this area over time. Result We performed a measure of 300 wing specimens of eastern honey bees and obtained the geometric morphological variation in the wing of A. cerana in Changbai Mountain. A total of 3,859,573 high-quality SNP loci were yielded via the whole-genome resequencing of 130 individuals in 5 geographic regions. Conclusion Corresponding geometric morphology and population genomics confirmed the particularity of the A. cerana in Changbai Mountain. Genetic differentiation at the subspecies level exists between populations in Changbai Mountain and remaining geographic regions, and a significant reduction in the effective population size and an excessive degree of inbreeding may be responsible for a substantial loss of population genetic diversity. Candidate genes potentially associated with cold environmental adaptations in populations under natural selection were identified, which may represent local adaptations in populations. Our study provided insights into the evolutionary history and adaptation of A. cerana in Changbai Mountain, as well as its conservation.

Fluorine‐silicone heterogeneous rubbers have been developed to address the issue of poor low‐temperature resistance in fluorine rubber. Bi‐functionalized SiO2 nanoparticles have been prepared as a nano‐compatibilizer to enhance the cooperation of fluorine‐silicon heterogeneous rubbers and improve their compatibility. Research has demonstrated that the nano‐compatibilizer can reduce the interfacial energy between the two phases and facilitate void‐free dispersion of the phases. Fluorine‐silicone heterogeneous rubbers with varying ratios have been synthesized to achieve a broad low‐temperature range, from −34 to −58°C. Additionally, the use of the nano‐compatibilizer enhances the thermal stability and mechanical properties of the rubbers. This study presents a novel approach utilizing bi‐functionalized SiO2 nanoparticles to promote the cooperation of fluorine‐silicone heterogeneous rubbers, resulting in customizable low‐temperature resistance for applications in sealing and hose materials.

Summary: Excessive patulin contamination in fruit juice products pose a significant risk to human health. However, there is a notable absence of a comprehensive and long‐term survey regarding the contamination of patulin in fruit juices within the Chinese market. The present study revealed a discernible decline in the patulin contamination levels, which were as follows: 60% (33/55), 18.28% (17/93), 0% (0/122), 15.58% (12/77), and 0% (0/63) at various survey time dates (2014, 2016, 2018, 2020, 2022). Among them, 18.18% (in 2014), 6.45% (in 2016), and 3.90% (in 2020) of samples exceeded the maximum limit concentration of 50 μg/L, respectively. Despite the presence of varying levels of patulin contamination, the average daily intake of patulin across all years did not present a discernible risk to human health. This investigation offers valuable insights for evaluating the extent of human exposure to patulin and establishing regulatory measures to ensure the safety of juice products. [ABSTRACT FROM AUTHOR]

Drawing upon construal level theory and regulatory fit literature, this research examined the effect of fit between humor and regulatory focus on audience engagement with health information on social media. The results of two studies showed that incongruity humor (vs. aggressive humor) induced greater social proximity between the source and the viewer, and humor type interacted with regulatory focus of a message to impact audience engagement. Specifically, incongruity humor paired with a prevention-focused message (vs. a promotion-focused message) resulted in greater content endorsement and health information engagement, whereas aggressive humor combined with a promotion-focused message (vs. a prevention-focused message) led to greater content endorsement. Results further identified processing fluency as a mediator of the fit effect on audience engagement. This research offers important theoretical and practical implications for public health interventions on social media. [ABSTRACT FROM AUTHOR]
