    Abstract Tryptophan (Trp) is an essential amino acid that can be metabolized via endogenous and exogenous pathways, including the Kynurenine Pathway, the 5-Hydroxyindole Pathway (also the Serotonin pathway), and the Microbial pathway. Of these, the Microbial Trp metabolic pathways in the gut have recently been extensively studied for their production of bioactive molecules. The gut microbiota plays an important role in host metabolism and immunity, and microbial Trp metabolites can influence the development and progression of various diseases, including inflammatory, cardiovascular diseases, neurological diseases, metabolic diseases, and cancer, by mediating the body's immunity. This review briefly outlines the crosstalk between gut microorganisms and Trp metabolism in the body, starting from the three metabolic pathways of Trp. The mechanisms by which microbial Trp metabolites act on organism immunity are summarized, and the potential implications for disease prevention and treatment are highlighted.

    Abstract Objective: Sepsis is one of major reasons of cardiorenal syndrome type 5 (CRS-5), resulting in irreversible tissue damage and organ dysfunction. Macrophage has been demonstrated to play key role in the pathophysiology of sepsis, highlighting the need to identify therapeutic targets for modulating macrophage phenotype in sepsis.
    Methods and results: In this study, a rapid-releasing hydrogen sulfide (H2S) donor NaSH, and a slow-releasing H2S compound S-propargyl-cysteine (SPRC) which is derived from garlic, have been studied for the immune-regulatory effects on macrophages. The NaSH and SPRC showed the potential to protect the heart and kidney from tissue injury induced by LPS. The immunohistochemistry of F4/80+ revealed that the infiltration of macrophages in the heart and kidney tissues of LPS-treated mice was reduced by NaSH and SPRC. In addition, in the LPS-triggered inflammatory cascade of RAW264.7 macrophage cells, NaSH and SPRC exhibited significantly inhibitory effects on the secretion of inflammatory cytokines, production of reactive oxygen species (ROS), and regulation of the macrophage phenotype from M1-like to M2-like. Moreover, autophagy, a crucial process involved in the elimination of impaired proteins and organelles during oxidative stress and immune response, was induced by NaSH and SPRC in the presence of LPS stimulation. Consequently, there was an increase in the number of mitochondria and an improvement in mitochondrial membrane potential. This process was mainly mediated by PINK1/Parkin pathway mediated mitophagy.
    Discussion: These results demonstrated that the immunoregulatory effects of H2S donors were through the PINK1/Parkin-mediated mitophagy pathway. Overall, our study provided a new therapeutic direction in LPS-induced cardiorenal injury.

    Abstract Purpose: To determine the treatment patterns and outcomes of pediatric retinal detachments (RDs) associated with hereditary vitreoretinopathies.
    Design: Retrospective cohort analysis using IRIS® Registry (Intelligent Research in Sight) database.
    Participants: Patients < 18 years old with a rhegmatogenous RD and a systemic disorder associated with vitreoretinal degeneration (e.g., Stickler syndrome) or other malformation of the vitreous from 2013-2019.
    Methods: Cases were identified using International Classification of Diseases, Ninth and Tenth Revisions (ICD-9, ICD-10) diagnostic codes from the IRIS® Registry cohort. Other hereditary vitreoretinopathies that are not encoded by specific ICD code(s) were captured by text search. Nonspecific vitreous abnormality ICD codes were also included. Exclusion criteria included traumatic retinal detachments using ICD codes for ocular trauma and serous or exudative retinal detachment. Surgical procedures were identified using Current Procedural Terminology (CPT) codes for repair of retinal detachment. Baseline demographic information collected included age, gender, race/ethnicity, geographic region of the provider location, and health insurance status.
    Main outcome measures: Main outcomes measured in this study were average time to first surgery, number of eyes presenting with bilateral detachments, and choice of initial surgical procedure.
    Results: A total of 2115 eyes of 1722 patients were identified (mean age, 10.4 years; 58% male). The median time to first surgery was 7 days (interquartile range, 40 days). One thousand four hundred seven eyes of 1134 patients had ≥ 1 year of follow-up, with 506 eyes (36%) developing a fellow eye RD. Thirty-three percent of patients presenting with bilateral detachments, and 349 eyes had initial RD surgery within 1 year of the index date documented by CPT code. Fellow eye detachment occurred a mean of 32 days after initial presentation. The mean number of surgeries per eye within 1 year was 1.68. Best-corrected visual acuity did not improve from a baseline 20/54 to 20/62. The initial procedure was most commonly complex RD repair (n = 176), followed by scleral buckle (n = 102), pars plana vitrectomy (n = 89), laser (n = 59), cryotherapy (n = 5), and pneumatic retinopexy (n = 5). There were 51 new diagnoses of glaucoma and 37 new diagnoses of aphakia within 1 year after the surgical procedure.
    Conclusions: IRIS Registry data provide insight into rare pediatric vitreoretinopathy-associated RDs, which have a high rate of reoperation and fellow eye involvement.

    Abstract The rabies virus is a neurotropic virus that causes fatal diseases in humans and animals. Although studying the interactions between a single rabies virus and the cell membrane is necessary for understanding the pathogenesis, the internalization dynamic mechanism of single rabies virus in living cells remains largely elusive. Here, we utilized a novel force tracing technique based on atomic force microscopy(AFM) to record the process of single viral entry into host cell. We revealed that the force of the rabies virus internalization distributed at (65±25) pN, and the time was identified by two peaks with spacings of (237.2±59.1) and (790.3±134.4) ms with the corresponding speed of 0.12 and 0.04 µm/s, respectively. Our results provide insight into the effects of viral shape during the endocytosis process. This report will be meaningful for understanding the dynamic mechanism of rabies virus early infection.

    Abstract Pumpkin polysaccharides (PPe) exhibit multiple bioactive properties, including the ability to reduce blood sugar and lipids. Our prior investigation discovered that hydrolysates (PPe-s) derived from PPe demonstrated stronger antioxidant capabilities than PPe. The objective of the current study was to explore the potential mechanism of PPe-s, utilizing Caenorhabditis elegans and MIN6 cells as models. The results of this investigation revealed that PPe-s exhibited strong scavenging ability towards ABTS

    Abstract Objective: To determine the timing of delayed retinal pathology in eyes presenting with acute posterior vitreous detachment (PVD).
    Design: Retrospective database study.
    Subjects: Patients in the Intelligent Research in Sight (IRIS) registry found to have acute PVD based on the International Classification of Diseases, Ninth and Tenth Revision, codes were followed.
    Methods: Patients coded to have a PVD from 2013 to 2018 along with common procedural technology coding of extended ophthalmoscopy were included. Ocular baseline characteristics included visual acuity, lens status, presence or absence of vitreous hemorrhage, myopia, lattice degeneration, and subspecialty training of the treating physician.
    Main outcome measures: Timing (days) to delayed retinal break or detachment RESULTS: A total of 434 046 eyes met inclusion/exclusion criteria, and 10 518 eyes (2.42%) presented with a delayed retinal break or detachment after initial PVD. The median time to retinal break and detachment after initial PVD was 42 (range, 1-365) days and 51 (range, 1-365) days, respectively. Eyes with vitreous hemorrhage (hazard ratio [HR], 9.30; 95% confidence interval [CI], 8.50-10.2), history of retinal break/retinal detachment in the fellow eye (HR, 3.91; 95% CI, 3.64-4.20), lattice degeneration (HR, 2.61; 95% CI, 2.35-2.90), and myopia (HR, 1.42; 95% CI, 1.33-1.53) were found to be at a higher risk of developing delayed break or detachment.
    Conclusions: Follow-up examination after initial PVD is necessary to diagnose delayed or missed retinal pathology. In eyes with no initial pathology, providers should consider repeat examination at least once within 6 weeks, and sooner for eyes with higher-risk features.

    Abstract Green citrus detection in citrus orchards provides reliable support for production management chains, such as fruit thinning, sunburn prevention and yield estimation. In this paper, we proposed a lightweight object detection YOLOv5-CS (Citrus Sort) model to realize object detection and the accurate counting of green citrus in the natural environment. First, we employ image rotation codes to improve the generalization ability of the model. Second, in the backbone, a convolutional layer is replaced by a convolutional block attention module, and a detection layer is embedded to improve the detection accuracy of the little citrus. Third, both the loss function CIoU (Complete Intersection over Union) and cosine annealing algorithm are used to get the better training effect of the model. Finally, our model is migrated and deployed to the AI (Artificial Intelligence) edge system. Furthermore, we apply the scene segmentation method using the "virtual region" to achieve accurate counting of the green citrus, thereby forming an embedded system of green citrus counting by edge computing. The results show that the mAP@.5 of the YOLOv5-CS model for green citrus was 98.23%, and the recall is 97.66%. The inference speed of YOLOv5-CS detecting a picture on the server is 0.017 s, and the inference speed on Nvidia Jetson Xavier NX is 0.037 s. The detection and counting frame rate of the AI edge system-side counting system is 28 FPS, which meets the counting requirements of green citrus.
