Alcoholic steatohepatitis (ASH) is one of the predominant causes of liver-related morbidity and mortality worldwide. However, effective therapy for ASH is still lacking. Notably, increasing evidence indicates ferroptosis may counteract the injury of the ASH. We recently identified a novel strategy for attenuating ASH by an effective adjuvant via ferroptosis through targeting MDMX. Verbenalin, which is a major compound in Verbena officials L (Verbenaceae), is generally recognized as a kind of safe food by the U.S. Food and Drug Administration. In this study, we found for the first time that Verbenalin is protective against alcoholic liver injury through transmission electron microscopy, Fe2+ content detection and other research methods. Its effect can not only inhibit oxidative stress such as MDA, SOD, GSH, ROS, 4-HNE and other related indicators, but also inhibit the ferroptosis of hepatocytes caused by alcohol. It was further confirmed by computer docking that verbenalin was targeted to inhibit MDMX activity, promote PPAR-alpha activation, and inhibit alcohol-induced ferroptosis in hepatocytes. Hence, Verbenalin might be employed as a promising natural supplement for alcoholic liver injury drug therapy.

Abstract Background and Purpose Previous studies have shown that TIGAR (TP53-induced glycolysis and apoptosis regulator) protects against cerebral ischemia/reperfusion injury via the improvement of the redox and energy homeostasis of neurons. TIGAR is found in the endoplasmic reticulum (ER) and nucleus but its role in ER stress is unclear. This study aimed to investigate the ER and nuclear translocation of TIGAR during ER stress and the influences of the nuclear TIGAR in cerebral ischemia/reperfusion-induced ER stress. Experimental Approach Mice were subjected to the middle cerebral artery occlusion/reperfusion. Cultured neurons were treated with oxygen and glucose deprivation, tunicamycin or thapsigargin. Key Results The increases in ATF4 target genes and ER stress-induced neuronal apoptosis were reduced by overexpression of TIGAR. Furthermore, increases in the localization of TIGAR and ATF4 to the nucleus were observed after in vitro and in vivo cerebral ischemia/reperfusion or ER stress models. The nuclear TIGAR interacts with ATF4 and inhibits the transcription of downstream pro-apoptotic genes of ATF4, resulting in protection against cerebral ischemia/reperfusion injury. Intriguingly, the translocation of TIGAR to the ER and nucleus and inhibition of the transcription of ATF4 is depend on Q141/K145 of TIGAR instead of its phosphatase activity and mitochondrial localization domains. Conclusion and Implications These results suggest that TIGAR translocates to the ER and the nucleus to interact with ATF4 after cerebral ischemia-reperfusion induced ER stress via its Q141/K145. The study uncovered a novel neuroprotective mechanism of TIGAR through regulating ER stress via a ATF4-mediated signaling pathway.

Background and Purpose: TREK-1 (TWIK-related potassium channel-1) is a subunit of the two-pore domain potassium (K2p) channel and is widely expressed in the brain. TREK-1 knockout mice were shown to have antidepressant-like effects, providing evidence for the channel’s potential as a therapeutic target. However, currently there is no good pharmacological inhibitor specifically targeting TREK-1 containing K2p channels that also displays similar antidepressant-like effects. Experimental Approach: We sought to find selective and potent inhibitors for TREK-1 related dimers both in vitro and in vivo. We synthesized and evaluated 2-hydroxy-3-phenoxypropyl piperidine derivatives yielding a library from which many TREK-1 targeting candidates emerged. Key Results: Hydroxyl-phenyl- (2a), piperidino- (2g), and pyrrolidino- (2h) piperidinyl substituted compounds showed high potencies to TREK-1 homodimers with significant antidepressant-like effects in forced swim test and tail suspension test. Interestingly, these compounds were found to have high potencies to TWIK-1/TREK-1 heterodimers, contrastingly, difluoropiperidinyl-4-fluorophenoxy (3e) and 4-hydroxyphenyl-piperidinyl-4-fluorophenoxy (3j) compounds had high potencies to TREK-1 homodimer but lower potency to TWIK-1/TREK-1 heterodimers without significant antidepressant-like effects. We observed positive correlation between inhibition potency to TWIK-1/TREK-1 and immobility time, and no correlation between inhibition potency to TREK-1 homodimer and immobility time. This was consistent with molecular docking simulations of selected compounds to TREK-1 homodimeric and TWIK-1/TREK-1 heterodimeric models. Existing antidepressant fluoxetine was also found to potently inhibit TWIK-1/TREK-1 heterodimers. Conclusion and Implications: Our study reveals novel potent TWIK-1/TREK-1 inhibitors 2a, 2g, and 2h as potential antidepressants and suggest that the TWIK-1/TREK-1 heterodimer could be a potential novel molecular therapeutic target for antidepressants.

African swine fever (ASF) is a high-consequence transboundary disease of domestic and wild swine often characterized by high case mortality rates. On July 29, 2021, the Dominican Republic announced the African swine fever virus (ASFV) had been detected in samples collected in early- to mid-July 2021. Retrospective testing of samples collected as part of a collaborative surveillance project between the United States and the Dominican Republic identified ASFV in samples collected as early as May 13, 2021. These detections represent a new outbreak of ASF in the Dominican Republic, which had been declared free of the disease since 1981. Overall, 73 whole genomes of ASFV were sequenced from clinical samples received during the outbreak across 18 provinces. The genomic sequence data have been deposited in public databases to support and expand global data sharing on this impactful disease. While the sequences show a high degree of nucleotide identity to publicly available ASFV genomes from Europe and Asia, they are genetically distant from genomes in the public repositories by at least 8 previously undescribed single nucleotide polymorphisms.

Neurofibromatosis type 1 (NF1) is not known to cause serious vascular complications. This report describes a 49-year-old man with NF1 who presented to our hospital in hemorrhagic shock due to vascular leakage within a neurofibroma tumor. Physicians should be aware that NF1 can cause a wide variety of vascular lesions.

Functional interaction between cancer cells and the surrounding microenvironment is still not sufficiently understood, which motivates the tremendous interest for the development of numerous in vitro and in vivo tumor models. Diverse parameters, e.g., transport of nutrients and metabolites, availability of space in the confinement, interaction with scaffolds, etc. make an impact on the size, shape, and metabolism of the tumoroids. Herein, we demonstrate the fluidics-based low-cost methodology to reproducibly generate the alginate and alginate-chitosan microcapsules and apply it to grow human hepatoma (HepG2) tumoroids of different dimensions and geometries. Focusing specifically on the composition and thickness of the hydrogel shell, permeability of the microcapsules is selectively tuned. The diffusion of the selected benchmark molecules through the shell has been systematically investigated using both, experiments and simulations, which is essential to ensure efficient mass transfer of small molecules and prevent large substances from reaching the encapsulated cells. Depending on available space, phenotypically different 3D cell assemblies have been observed inside the capsules, varying in the tightness of cell aggregations and their shapes. Metabolic activity of tumoroids in microcapsules was confirmed by tracking the turnover of testosterone to androstenedione with chromatography studies in a metabolic assay. Because of the high reproducibility, compartmentalization, and facile tuning of the shell thickness and permeability, our system is not only a great platform for the formation of cancer tumoroids, but also a promising tool for the design and engineering of other cells.

Two patients with concomitant vitiligo and autoimmune atrophic gastritis a comparative histological study on skin and gastric mucosa were preformed.Common findings were seen in both specimens .Down expression of E-Cadherin and Collagen IV leading to detachment of melanocytes and parietal cells in addition to CD8 and CD4 Infiltration were detected.

The present work consisted in developing computational routine for prediction and characterization ignition delay time in shock tube. The work was the development of computational routines to characterize the shock wave parameters the ignition delay times of diesel to validate the experimental tests carried out in shock tube conducted by Santana and compare it with the experimental tests and numerical simulations carried out by others authors available in the literature. A linear regression of the experimental tests conducted by Santana et al [3] with conventional diesel was performed to obtain the Arrhenius equation for numerical simulation of the ignition delay time of diesel under the following conditions: temperatures from 880 to 1300K, pressures 24 bar and equivalence ratio 1. The results show good prediction between experimental and simulations. Were found delay times ranging from 425 to 1890μs. Considering all temperature range, the difference between the experimental and simulated test was approximately 15%, this difference also can be explained by the measurement in the shock tube, that the ignition delay time was calculated by the time difference between the passage of the shock wave by the pressure sensor and the start of the ignition detected by the luminosity detection sensor.

This paper is concerned with the time-decay rates of the strong solutions of the three dimensional non-isentropic compressible magnetohydrodynamic (MHD) system. First, motivated by Pu–Guo’s result [Z. Angew. Math. Phys. 64 (2013) 519–538], we establish the existence result of a unique local-in-time strong solution for the MHD system. Then, we derive a priori estimates and use the continuity argument to obtain the global-in-time solution, where the initial data should be bounded in L1-norm and is small in H2-norm. Finally, based on Fourier theory and the idea of cancellation of a low-medium frequent part as in [Sci. China Math. 65 (2022) 1199–1228], we get the optimal time-decay rates (including highest-order derivatives) of strong solutions for non-isentropic MHD fluids. Our result is the first one concerning with the optimal decay estimates of the highest-order derivatives of the non-isentropic MHD system.

Background: While prior data have suggested worse outcomes in women after acute type A aortic dissection (ATAAD) repair when compared to men, results have been inconsistent across studies over time. This study sought to evaluate the impact of sex on short- and long-term outcomes after ATAAD repair. Methods: This was a retrospective study utilizing an institutional database of ATAAD repairs from 2007 to 2021. Patients were stratified according to sex. Kaplan-Meier survival estimation and multivariable Cox regression were performed. Supplementary analysis using propensity score matching was also performed. Results: Of the 601 patients who underwent ATAAD repair, 361 were males (60.1%) and 240 (39.9%) were females. Females were significantly older, more likely to have hypertension, and more likely to have chronic lung disease. Females were also significantly more likely than males to undergo hemiarch replacement, while males were significantly more likely than females to undergo total arch replacement and frozen elephant trunk. Operative mortality was 9.4% among males and 13.8% among females, though this was not a statistically significant difference (p=0.098). Postoperative complications were comparable between groups. Kaplan-Meier survival estimates were similar for men and women, and, on multivariable Cox regression, sex was not significantly associated with long-term survival (HR 1.00, 95% CI: 0.73, 1.37, p=0.986). Outcomes remained comparable after supplementary propensity score matched analysis. Conclusion: ATAAD repair can be performed with comparable short-term and long-term outcomes in both men and women.

Background VIV-TAVR is established and provides good initial clinical and hemodynamic outcomes. Lacking long-term durability data baffle the expand to lower risk patients. For those purposes, the present study adds a hemodynamic 3-years follow-up. Methods A total of 77 patients underwent VIV-TAVR for failing aortic bioprosthesis during a 7-years period. Predominant mode of failure was stenosis in 87.0%. Patients had a mean age of 79.4±5.8 years and a mean logistic EuroSCORE of 30.8±15.7%. The STS-PROM averaged 5.79±2.63%. Clinical results and hemodynamic outcomes are reported for 30-days, 1-, 2- and 3-years. Completeness of follow-up was 100% with 44 patients at risk after 3-years. Follow-up ranged up to 7.1 years. Results Majority of the surgical valves were stented (94.8%) with a mean labeled size of 23.1±2.3mm and true-ID of 20.4±2.6mm. A true-ID ≤21mm had 58.4% of the patients. Self-expanding valves were implanted in 68.8% (mean labeled size 24.1±1.8mm) and balloon-expanded in 31.2% (mean size 24.1±1.8mm). No patient died intraoperatively. Hospital mortality was 1.3% and three-years survival 57.1%. All patients experienced an initial significant dPmean-reduction to 16.8±7.1mmHg. After 3-years mean dPmean raised to 26.0±12.2mmHg. This observation was independent from true-ID or type of TAVR-prosthesis. Patients with a true-ID ≤21mm had a higher initial (18.3±5.3mmHg vs. 14.9±7.1mmHg; p=0.005) and dPmean after 1-year (29.2±8.2mmHg vs. 13.0±6.7mmHg; p=0.004). There were no significant differences in survival. Conclusions VIV-TAVR is safe and effective in the early period. In surgical valves with a true-ID≤21mm inferior hemodynamic and survival outcomes must be expected. Nonetheless, also patients with larger true-ID’s showed steadily increasing transvalvular gradients. This raises concern about durability.

Duodenal diverticula perforation due to an impacted bezoar is a rare disease. Surgical treatment is associated with high rates of complications and mortality; therefore, treatment strategies must be carefully decided. Endoscopic treatment offers significant benefits to patients over surgery.

Cycloarenes are a particular category of polycyclic aromatic hydrocarbons that have intrigued the experimental world for decades owing to the distinctiveness of their atomic and electrical configurations. They are suitable venues for investigating fundamental problems of aromaticity, particularly those involving the π-electron distribution in complex aromatic structures. Cycloarenes have recently attracted much attention due to their distribution as analogs for graphene pores. Kekulene is the member of this family that has been studied the most. For decades, its electrical structure has been a source of contention. It’s a doughnut-shaped chemical structure of circularly stacked benzene rings with interesting structural characteristics that lend themselves to experimental investigations like π-electron conjugation circuits. To predict their properties, topological characterization of such structures is required. This paper discusses two new series of big polycyclic compounds made by tessellating many kekulene doughnuts to make a hypothetical molecular belt with multiple cavities

Oligomeric protein interfaces involve non-covalent attractive forces plus potential steric entanglement. 70 years ago, Crick proposed a “Knobs in Holes” model for coiled-coil protein interfaces. Subsequently, modifications to this model have been proposed, describing either a “leucine zipper”, “jigsaw puzzle”, or a “peptide Velcro” interface. These principally describe forms of steric entanglement that may enhance oligomer stability; however, such entanglement has not been rigorously evaluated since it is not possible to experimentally eliminate intrinsic noncovalent attractive forces. 3D printing provides a novel means to evaluate steric entanglement of protein interfaces in the absence of attractive forces. Surprisingly, quantitation of the energy required to dissociate various coiled-coil protein interfaces of 3D printed protein models suggests minimal steric entanglement. Conversely, evaluation of domain swapped interfaces of symmetric protein oligomers, differing by circular permutation, identifies extensive potential steric entanglement. Combined with available experimental data, the results suggest that steric entanglement of a protein interface can contribute to kinetic trapping of both folding and unfolding pathways. Steric entanglement of protein interfaces is therefore postulated to be an undesirable property for naturally evolved and designed protein oligomers.

The existence of hypopigmentation such as leucism is the result of inbreeding in isolated populations of wildlife and it is associated with environmental stressors. This anomaly may reduce survival rates. Leucism has been record in wildlife, but overall, it is considered very rare. There have been few records of mantled howler monkeys with leucism in Mexico and Costa Rica, but whole-body leucism in howler monkeys from South America was unknown. In this article, we report for the first-time documented cases of whole-body leucism in young individuals of mantled howler monkeys Alouatta palliata in an isolated remanent of tropical dry forest in southwestern Ecuador known as Cerro Blanco Protective Forest. In total, we found two individuals: a juvenile female and a juvenile male in October 2021. We also include a short report about the observation of two seedlings of Dichapetalum (Dichapetalaceae) showing albinism. The report of howler monkeys with whole-body leucism may be caused by the interaction of two processes: inbreeding because of isolated populations and air pollution with sulphur. Thus, immediate management strategies must be considered to significantly increase connectivity with other populations of howler monkeys and reduce air pollution in Guayaquil. Our findings also reveal that hypopigmentation is becoming more frequent in howler monkey´s population along its distributional range. Therefore, we encourage the community to consider a regional management strategy.

Telomeres, the terminal repetitive DNA sequences at the ends of linear chromosomes, have strong associations with longevity in some major taxa. Longevity has been linked to rate of decline in telomere length in birds and mammals, and absolute telomere length seems to be associated with body mass in mammals. Using a phylogenetic comparative method and 30 species of birds, we examined longevity (reflected by maximum lifespan), absolute telomere length, the rate of change in telomere length (TROC), and body mass (often strongly associated with longevity) to ascertain their degree of association. We divided lifespan into two life-history components, one reflected by body size (measured as body mass), and a component that was statistically independent of body mass. While both lifespan and body mass were strongly associated with a family tree of the species (viz., the phylogeny of the species), telomere measures were not. Telomere length was not significantly associated with longevity or body mass, or our measure of mass-independent lifespan. TROC, however, was strongly associated with mass-independent lifespan, but to a lesser degree with body mass. Our results supported an association of TROC and longevity, in particular longevity that was independent of body size and part of the pace-of-life syndrome of life histories.

Background The current diagnostics of fish allergy lack sufficient accuracy such that more reliable tests such as component-resolved diagnosis (CRD) are urgently needed. This study aimed at identifying fish allergens of salmon and grass carp and evaluating the sensitization pattern towards the identified allergens in fish allergic subjects from two distinct populations in Asia. Methods One hundred and three fish allergic subjects were recruited from Hong Kong (67 subjects) and Japan (46 subjects). Western blot and mass spectrometry were used to identify allergens from salmon and grass carp. Fish allergens were purified and tested against 96 sera on ELISA to analyze patients’ sensitization pattern. The protein profiles of salmon meat prepared under different cooking methods until core temperature reached 80°C were evaluated by SDS-PAGE and mass spectrometry. Results Three common allergens between salmon and grass carp, namely enolase, glycerldehyde-3-phosphate dehydrogenase (GAPDH) and parvalbumin, and two salmon-specific allergens collagen and aldolase were identified. Parvalbumin was the major allergen for both fishes showing an overall sensitization rate of 74.7%, followed by collagen (38.9%), aldolase (38.5%) and enolase (17.8%). Japanese subjects showed more diverse allergen sensitization pattern and more frequent IgE-binding to heat-labile salmon allergens. Compared with steaming and boiling, cooking by baking and frying retained more fish proteins inclusive of heat-labile allergens. Conclusions Fish allergic patients from different Asian populations show varying fish allergen sensitization profiles. The relevant extracts and components for diagnosis are population-dependent but parvalbumin and collagen are important biomarkers. Cooking methods modify allergen composition of salmon and appear to influence patients’ allergic manifestations.

Foot and mouth disease (FMD) is a highly contagious disease affecting cloven-hoofed animals which has been well documented as one of the major animal diseases that causing serious economic loss of livestock sectors. The disease is endemic in many countries, particularly in Asia and Africa. Indonesia has declared disease-free country since 1986 and the World Organization of Animal Health (WOAH/OIE) has recognised Indonesia as FMD-free country without vaccination in 1990. However, FMD virus was detected from a number of disease outbreaks in cattle and goat in Indonesia in May 2022. This study report for the first time the detection and identification of serotype O/ME-SA/Ind-2001 lineage in Indonesia. Although the Indonesian serotype O/ME-SA/Ind-2001 viruses appeared belonging to the Ind-2001e sublineage, they formed a unique cluster with 95.3% average nucleotide sequence similarity to Ind-2001e viruses from other Asia countries. The source of virus incursion into Indonesia is still unresolved; however, illegal trade of live animals from endemic areas in Southeast Asia is the suspected route which should be further investigated.

The sources of the replenishment and hydrogeochemical evolution of acid mine drainage (AMD) from abandoned mines are issues of public concern around the world. To reveal the sources of groundwater replenishment and the nature of the hydrogeochemical processes that control the evolution of water quality in the multi-aquifer system of the abandoned Dashu pyrite mine in southwest China, the main control mechanisms of groundwater evolution are examined, based on hydrogeochemical analysis methods in combination with environmental isotope tracing methods, which in turn clarify the hydrogeochemical causes of groundwater pollution. According to the hydrogeochemical and stable and unstable isotope analyses, the diversity of groundwater hydrochemical types in the study area reflects the complexity of the groundwater hydrogeochemical environment, where groundwater is formed after the mixing of atmospheric precipitation and groundwater over multiple periods. The analysis of 2H, 18O, and T is used to identify the main sources of hydraulic connection between aquifers, groundwater, and mine water. The results show that there are close hydraulic connections between aquifers. Mine water and groundwater mainly come from the groundwater in the Quaternary accumulation platform. The results of the ion analysis and sulfur isotope tracing show that the main ions in the groundwater are derived from mineral dissolution/precipitation, cation exchange, pyrite oxidation, and other water-rock interaction processes. The sulfur in the groundwater mainly comes from the dissolution of gypsum, while the main source of sulfur in the mine water is the oxidation of pyrite, indicating that pyrite oxidation and cation exchange are the dominant processes in the mine water. The key hydrogeochemical processes were simulated using the reverse hydrogeochemical simulation method. The results show that the mining activities changed the water levels and flow conditions, strengthened the interaction between groundwater and aquifer lithology, which in turn affected the accompanying hydrogeochemical processes. After all of the mine was abandoned, it saw the cross-contamination between the aquifer and mine water. These results provide theoretical guidance for the identification of sources and key hydrogeochemical processes affecting groundwater and pollutants in the abandoned Dashu pyrite mines and similar abandoned mines with multiple aquifers, and can, therefore, provide technical support for the preparation of source prevention and control plans.

Background: Cardiac injury has been described in children with both acute COVID-19 and the multisystem inflammatory syndrome in children (MIS-C). Strain has been shown to be a sensitive measure of systolic function and can be used for detecting subclinical left ventricular (LV) dysfunction. We sought to describe strain findings in both groups on initial presentation and outpatient follow up. Methods: A retrospective study analyzing echocardiograms of all patients presenting with acute COVID-19 infection and MIS-C at our institution between March 2020 and December 2020 was performed. TOMTEC software was used for strain analysis in both study groups (COVID-19 and MIS-C) and age matched healthy controls. Regional strain was obtained and comparison amongst groups was performed using the Mann-Whitney U test. Strain was compared against LV ejection fraction (EF) as measured by 5/6 area length method. Results: 45 patients (34 MIS-C and 11 COVID-19) met inclusion criteria. There was a statistically significant decrease in LV longitudinal strain (p <0.001), LV circumferential strain (p <0.001) and left atrial strain (p = 0.014) in the MIS-C group when compared to the control group. There was a statistically significant decrease in LV longitudinal strain (p = 0.028) in the acute COVID-19 group. All patients with abnormal LVEF had abnormal strain. However 14 patients (41%) in the MIS-C group and 3 (27%) in the acute COVID-19 group had preserved LVEF but abnormal strain. Abnormal strain persisted in one-third of patients in the MIS-C and acute COVID-19 groups on outpatient follow up. Conclusion: Patients with MIS-C and acute COVID-19 can develop myocardial dysfunction as seen by abnormal strain. Strain may provide an additional tool in detecting subtle myocardial dysfunction. It can be routinely employed at diagnosis and at follow up evaluation of these patients.

Despite their close links, ecology and evolution have remained separate disciplines to this day. Breaking down the wall between the two disciplines is essential for at least two reasons. First, this wall is an obstacle to the study of most microorganisms, which constitute a large part of the Earth's biodiversity. Asexual reproduction, gene transfer and the lack of a clear definition of the species taxonomic level blur the distinction between ecological changes in species abundances and evolutionary changes in genotype frequencies in microbes. Second, a key question that biodiversity science will have to address in the coming decades is how ecological systems will cope with rapid environmental change. Generalising the concept of adaptation across multiple timescales and levels of organisation would provide an integrative framework for studying the combined ecological and evolutionary responses to environmental change, and thus help us to address one the major scientific challenges of our time.

Background: Despite the WHO recommendation that pregnant women be prioritised for seasonal influenza vaccination, coverage in the Western Pacific Region remains low. Our goal was to provide additional data for the Western Pacific region about the value of maternal influenza vaccination to pregnant women and their families. Methods: We conducted a 16-year retrospective cohort to evaluate risks associated with influenza-associated maternal acute respiratory infection (ARI) in New Zealand. ARI hospitalisations during the May-September influenza season were identified using select ICD-10-AM primary and secondary discharge codes from chapter J00-J99 (diseases of the respiratory system). Cox proportional hazards models were used to calculate crude and adjusted hazard ratios (aHR) and 95% confidence intervals (CI). Results: We identified 822,391 pregnancies among New Zealand residents between 2003 and 2018; 5,095 (0.6%) had >1 associated ARI hospitalisation during the influenza season; these pregnancies were at greater risk of preterm birth (aHR 1.5, 95% CI 1.3-1.7), and low birthweight (aHR 1.7, 95% CI 1.5-2.0) than pregnancies without such hospitalisations. We did not find an association between maternal ARI hospitalisation and fetal death (aHR 1.1, 95% CI 0.6-1.4) during the influenza season. Maternal influenza vaccination was associated with reduced risk of preterm birth (aHR 0.8, 95% CI 0.7-0.9), and low birthweight (aHR 0.9, 95%CI 0.8-0.9), and fetal death (aHR 0.5%, 95% CI 0.3-0.7). Conclusion: In this population-based cohort, being hospitalised for an ARI during the influenza season while pregnant was a risk-factor for delivering a preterm or a low birthweight infant and vaccination reduced this risk.

Species richness, evenness, and taxonomic diversity have been proposed and used as indicators of biodiversity. However, the governing equations for the dynamics of these indicators are often unknown and an understanding of their mechanism is limited. By employing a nonlinear forecasting-based method to the time series of 10 biodiversity indicators of a marine fish community, we aimed to detect changes in their dynamics and classify the indicators according to the level and timing of dynamic changes. The 10 biodiversity indicators were classified into three super-groups: Group I (species richness and community center of distribution) with the most unchanged dynamics; Group II (species diversity and total abundance) with dynamics that had an abrupt change in the middle, presumably due to an increase in local temperature; and Group III (species evenness) with highly variable dynamics. Finally, a hypothesis regarding the mechanistic basis of the dynamic similarities between the biodiversity indicators was proposed.
