Globally acute myocardial infarction is the leading independent cause of unexpected death. This study aimed to explore the diagnostic and molecular impact of miR-21, miR-488, and miR-126 in acute myocardial infarction patients (AMI). We enrolled 95 non-ST-elevation myocardial infarction (NSTEMI) patients, 152 ST-elevation myocardial infarction (STEMI) patients, and 95 healthy individuals, additionally using three-month-old mice and their ventricular-derived H9c2 cells. The circulatory plasma miR-21 and miR-488 levels were significantly upregulated, while plasma miR-126 levels were remarkably downregulated in NSTEMI and STEMI subjects. The receiver operating characteristic curve showed that plasma miR-21, miR-488, and miR-126 were able to clearly differentiate NSTEMI and STEMI from healthy subjects. Moreover, H9c2 hypoxic cells treated with inhibitor miR-21 markedly reduced intracellular ROS levels, capase-3 activities levels, and cellular apoptosis rates and significantly enhanced cellular viability through up regulation of Smad-7 mRNA and protein expressions. In geriatric STEMI and NSTEMI subjects, plasma miR-21 levels were evidently higher than in comparatively younger subjects. Upregulated plasma miR-21 and miR-488 levels and downregulated miR-126 levels might be considered potential clinical biomarkers for myocardial infarction patients, while inhibition of miR-21, which significantly reduced hypoxia-exposed H9c2 cellular injury via targeting Smad-7, could be a new therapeutic target for AMI patients. Low levels plasma miR-21 may have a significant impact on delaying the aging process. Full article

Acute mesenteric ischemia (AMI) is a life-threatening condition characterised by oxidative stress, inflammation, apoptosis, and necrosis of intestinal epithelial cells. Different drugs with vasoactive, antioxidant, and anti-inflammatory properties have been used to treat AMI. Levosimendan is a drug with proven anti-ischemic effects used in the management of acute congestive heart failure. This study evaluated the protective effects of levosimendan pretreatment on intestinal, as well as lung, heart, and kidney tissue in a rat model of mesenteric artery ischemia/reperfusion (I/R) injury. Male Wistar rats (N = 24) were divided into four groups: control, I/R, levosimendan (LS) 1 mg/kg i.p, and LS + I/R (1 mg/kg i.p. 30 min before injury). I/R by itself caused elevation of oxidative markers (thyobarbituric acid reactive species (TBARS), hydrogen peroxide (H₂O₂), super oxide anjon radical (O₂⁻), and nitrogen dioxide (NO₂⁻)), induced inflammation (macrophage infiltration and Interleukin-6 (IL-6) production), and apoptosis (nuclear factor kappa light-chain enhancer of activated B cells (NF-κB), cleaved caspase-3 (CC3), and terminal deoxy-nucleotidyl transferase (TdT)-mediated dUTP nick end labelling (TUNEL)). Levosimendan pretreatment significantly reduced oxidative stress markers and enhanced antioxidant defences (catalase (CAT), reduced glutathione (GSH), and superoxide dismutase (SOD)). Histological analysis revealed reduced mucosal damage and preserved goblet cells in intestinal tissue. Similar protective effects of levosimendan were observed in other organs such as lung, heart, and kidney. Immunohistochemistry showed reduced epithelial apoptosis and upregulation of antioxidant and anti-inflammatory proteins. These findings highlight levosimendan’s ability to protect mesenteric I/R tissue injury and multi-organ damage by suppressing oxidative stress, inflammation, and apoptosis, emphasising its therapeutic potential in clinical settings.

Sea urchin aquaculture has experienced remarkable growth in recent years. However, this growth has been accompanied by increased disease prevalence. Notably, spotting disease has particularly severe impacts. In this study, we isolated the pathogen HZ-3-2 from 10 sea urchins with spotting disease, and it was identified as Vibrio splendidus through morphological observations, 16S rDNA sequencing, and whole-genome sequencing. Subsequently, experimental infection confirmed that V. splendidus (HZ-3-2) is the causative agent of spotting disease in this outbreak. The drug sensitivity confirmed the presence of drug resistance genes, such as CPR, QNRS5, and rsmA, which were identified in the genome. The tests indicated that V. splendidus was sensitive to various antibiotics, including fluoroquinolones and florfenicol. Finally, we used the transcriptome to explore the molecular response of the diseased sea urchin. Compared to the control group, a group of sea urchins immersed in a pathogen suspension with a concentration of 10⁷ CFU/mL (group M) resulted in 439 annotated differentially expressed genes. KEGG pathway analysis indicated significant activation of cholesterol metabolism and starch and sucrose metabolism in the S. intermedius. This study highlights the genes NPC1, AMY2A, and MGAM as critical regulators of energy metabolism, and cholesterol synthesis in infected sea urchins. These findings confirm V. splendidus as the bacterium responsible for spotting disease and provide valuable insights into the intestinal molecular response of S. intermedius to infection.

Dunaliella salina, a unicellular and eukaryotic alga, has been found to be one of the most salt-tolerant eukaryotes with a wide range of practical applications. To elucidate the underlying molecular mechanisms of D. salina in response to salinity stress, we performed transcriptome sequencing on samples under different stress conditions. A total of 82,333 unigenes were generated, 4720, 1111 and 2611 differentially expressed genes (DEGs) were identified under high salt stress, oxidative stress and hypertonic stress, respectively. Our analysis revealed that D. salina responds to salinity stress through a complex network of molecular mechanisms. Under high salt stress, starch degradation is regulated by AMY (α-amylase) and PYG (glycogen phosphorylase) with alternative expression patterns. This process is hypothesized to be initially constrained by low ATP levels due to impaired photosynthesis. The clustering analysis of DEGs indicated that starch and sucrose metabolism, as well as glycerol metabolism, are specifically reprogrammed under high salt stress. Glycerol metabolism, particularly involving GPDHs, plays a crucial role in maintaining osmotic balance under salinity stress. Key glycerol metabolism genes were up-regulated under salinity conditions, indicating the importance of this pathway in osmotic regulation. The G3P shuttle, involving mitochondrial GPDHs (c25199_g1 and c23777_g1), contributes to redox imbalance management under high salt, oxidative and hypertonic stresses. Notably, c23777_g1 is involved in the G3P shuttle under high salt, oxidative and hypertonic stresses, while c25199_g1 is specifically induced by hypertonic stress. The R2R3-MYB gene (c23845_g1) may respond to different effects of salinity stress by regulating the transcription of ROS-related genes. Our study provides a detailed understanding of the molecular responses of D. salina to salinity stress. We reveal the critical roles of starch and sucrose metabolism, glycerol metabolism and transcription factors in the D. salina adaptation to salinity. Full article

The incidence of fatal anaphylaxis is increasing, but there is still no recognized “golden standard” for forensic diagnosis. Due to its non-specific symptoms, especially cardiovascular symptoms without cutaneous changes, it can easily be misdiagnosed as acute myocardial infarction. Here, we established rat models (n = 12) of fatal anaphylaxis (FA), acute myocardial infarction (AMI), and coronary atherosclerosis with anaphylaxis (CAA). The untargeted metabolomics of plasma and 16S rRNA sequencing of fecal matter was performed, and a random forest was used to identify potential biomarkers. Three metabolites (tryptophan, trans-3-indole acrylic acid, and imidazole acetic acid) and three microbial genera (g_Prevotellaceae_Ga6A1_group, g_UCG_008, and g_Eubacterium_hallii_group) were identified as potential biomarkers for distinguishing anaphylaxis and non-anaphylaxis. The classification model of plasma metabolites showed a much better discriminatory performance than that of microbial genus, serum IgE, and tryptase. The performance of the microbial genera was superior to the serum IgE but inferior to the serum tryptase. Forensic samples of fatal anaphylaxis and non-anaphylaxis deaths (n = 12) were collected for untargeted metabolomics detection. The results showed that among the three identified metabolic biomarkers, tryptophan has better stability in cadaveric blood samples. Its diagnostic performance (AUC = 87.1528) was superior to serum IgE and tryptase, making it more suitable as a postmortem biomarker of fatal anaphylaxis. Full article

Cardiovascular diseases remain the leading cause of death worldwide, highlighting the urgent need for novel therapeutic strategies. The Mediterranean diet is renowned for its cardiovascular benefits, largely attributed to extra virgin olive oil (EVOO) and its phenolic compounds, particularly hydroxytyrosol (HT). HT, a potent antioxidant and anti-inflammatory agent, has demonstrated significant therapeutic potential in mitigating myocardial damage following acute myocardial infarction (AMI). However, there is a notable lack of published evidence regarding the effects of HT administration in the context of acute ischemia/reperfusion (I/R) injury, making this study a novel contribution to the field. This study aimed to evaluate the cardioprotective effects of HT using the Langendorff technique in an isolated mouse heart ischemia/reperfusion (I/R) model. Mice were administered a single intraperitoneal dose of HT (10 mg/kg) 24 h prior to the I/R protocols, and parameters such as the infarct size, mitochondrial function, and redox balance were assessed. The results revealed a remarkable 57% reduction in infarct size in HT-treated mice compared to untreated controls. HT treatment also improved mitochondrial bioenergetics, as evidenced by the increased membrane potential (ΔΨm), enhanced oxygen consumption, and reduced hydrogen peroxide (H₂O₂) production. Furthermore, HT restored the activity of the mitochondrial respiratory complexes, notably Complex I, even under I/R conditions. These findings highlight the efficacy of HT in reducing oxidative stress and preserving mitochondrial function, critical factors in cardiac disease. In conclusion, HT emerges as a promising therapeutic agent for ischemic heart disease, demonstrating both preventive and restorative potential. Future research should explore its clinical applicability to advance cardiovascular disease management. Full article

Plant responses to heat stress include complex transcriptional networks and protein regulations in which BTB/POZ-MATH (BPM) proteins participate as a part of ubiquitin-mediated protein degradation. Arabidopsis thaliana contains six BPM genes involved in responses to environmental changes, including heat. Seedlings overexpressing BPM1 (oeBPM1), seedlings with downregulation of BPM1, 4, 5, and 6 (amiR-bpm) and wild type were exposed to 37 °C for 6 h. Treatment caused stronger decline of photosynthesis in oeBPM1 than in amiR-bpm and wild type, although all seedlings recovered after 24 h at 24 °C. The activity of the antioxidant enzymes catalase, guaiacol peroxidase, and ascorbate peroxidase remained unchanged in oeBPM1, but increased in amiR-bpm and wild type. Heat stress induced HSP70 and HSP90 in all seedlings but expression remained notably higher in amiR-bpm after recovery. DREB2A and HSFA3 expression increased in all seedlings immediately after stress, with the strongest induction in amiR-bpm. In amiR-bpm and wild type, BPM2 expression was induced immediately after exposure, while BPM1, BPM3, BPM4, and BPM6 were upregulated in wild type after recovery. In oeBPM1 seedlings, BPM4 expression decreased and BPM6 expression increased immediately after treatment at 37 °C for 6 h. The results suggest that BPM proteins modulate heat stress response by influencing photosynthesis, activation of antioxidant enzymes, accumulation of HSPs, and expression of heat-responsive genes, thus contributing to the different physiological strategies observed in A. thaliana lines with altered expression of BPM genes.

Background and Objectives: Stress and type A personality are known to be risk factors for the development of acute myocardial infarction (AMI), and depression is both a risk factor for AMI and a prognostic factor. In this study, we aimed to evaluate the relationship between psychological flexibility, perceived stress level, depression, and anxiety in AMI patients. Material and Methods: The study included 89 patients with a diagnosis of AMI and 89 volunteer participants with no previous history of coronary angiography and no diagnosis of AMI. Patients were evaluated with the Acceptance and Action Questionnaire (AAQ)-II, the Hospital Anxiety and Depression Scale (HADS), and the Perceived Stress Scale (PSS)-14. Results: A strong positive statistically significant correlation was found between the Perceived Stress Scale score and HAD-II (r = 0.697 p < 0.001), HAD-Anxiety (r = 0.715 p < 0.001), and HAD-Depression (r = 0.657 p < 0.001) scores. A statistically significant moderate positive correlation was found between the HAD-Depression Scale and HAD-Anxiety (r = 0.593 p < 0.001) and AAQ-II (r = 0.530 p < 0.001) scores. A strong positive statistically significant correlation was found between the HAD-Anxiety Scale and AAQ-II (r = 0.809 p < 0.001) scores. Conclusions: Investigation of psychological flexibility, anxiety, and depression in AMI patients with scales such as AAQ-II, PSS-14, and HADS may help early diagnosis and treatment of individuals at risk for psychiatric disorders.

Background/Objectives: Large clinical trials have established the optimal antiplatelet strategy in the wide spectrum of coronary artery disease. However, data are scarce regarding MINOCA and the aim of our study is to present data from the current clinical practice. Methods: A total of 151 patients were included in this study after exclusion of 27 patients with myocarditis and other diagnoses. A cardiac magnetic resonance (CMR) performed at 123/151 patients demonstrated an ischemic pattern of late gadolinium enhancement (LGE) confirming the diagnosis of true acute myocardial infarction (AMI) in 42 cases (28%). Based on multimodality imaging and clinical judgement, Takotsubo syndrome (TTS) was diagnosed in 55 patients (36%), whereas CMR failed to reveal abnormal findings in 54 cases (36%), categorized as MINOCA of unknown origin. Results: Regarding antithrombotic prescriptions at discharge, 38% of patients received dual antiplatelet (DAPT) or dual antithrombotic therapy (DAT, 1 antiplatelet plus 1 anticoagulant), 49.7% received single antiplatelet (SAPT) or anticoagulant, and 12% received no antithrombotic treatment. Univariate analysis showed that the likelihood of prescribing DAPT or DAT was associated with left ventricular ejection fraction (LVEF) (r = 0.202, p = 0.013), atherosclerotic lesions on coronary angiography (r = 0.303, p < 0.001), prior use of anticoagulants (r = −0.258, p = 0.001), and marginally with the INTERTAK score (r = −0.198, p = 0.044). A multivariable model, adjusted for age, LVEF, ECG abnormalities, and history of anticoagulant use, confirmed the independent association between angiographic evidence of atherosclerosis and the decision for DAPT/DAT (OR: 0.334, 95% CI: 0.307–0.813, p < 0.001). However, the initial treatment decision did not seem to impact 2-year prognosis in our population. Conclusions: Our study results reveal that decision making in the antithrombotic strategy for MINOCA patients poses a challenge in clinical practice. More robust data are required for definite conclusions on the prognostic implications. Full article

Background: International guidelines recommend the use of high-sensitivity cardiac troponin (hs-cTn) I and T methods for the detection of myocardial injury as a pre-requisite for the diagnosis of acute myocardial infarction (AMI) in patients admitted to the emergency department. Recently, Mindray (Mindray Bio-Medical Electronics Co., Ltd., Shenzhen, China) has introduced a new chemiluminescence immunoassay (CLIA) for the detection of the cTn complex. The present study aims to verify and validate the hs-cTnI Mindray assay on the new automated CL2600i analyzer compared to the routine Alinity-i series instrument by Abbott (Abbott, Chicago, IL, USA). Methods: This study evaluated linearity, precision through the 5 × 5 protocol, methodological comparison on plasma and serum matrices, hs-cTnI 99th percentile imprecision, and the hs-cTnI detection rate in a healthy population. Results: The results obtained proved that the performance of the Mindray hs-cTnI test on the CL2600i platform was closely comparable to the Abbott Alinity-i system (plasma R²: 0.974; serum R²: 0.995). The CVs were consistently low, and no significant differences were reported. Excellent analytical performance, with high sensitivity, was also observed in the healthy population (overall detection rate: 79%), as well as good linearity within the measuring range (R²: 0.994). Conclusions: The Mindray hs-cTnI test confirms its robustness and utility in routine practice as an advanced assay. The new technology, with more sensitive detection methods, may improve the accuracy and reliability of cardiac biomarker testing, ultimately leading to better outcomes in the management of patients with AMI and other cardiac conditions.

Cotton leaf curl Kokhran virus-Burewala (CLCuKoV-Bur) has a circular single-stranded ssDNA genome of 2759 nucleotides in length and belongs to the genus Begomovirus (family, Geminiviridae). CLCuKoV-Bur causes cotton leaf curl disease (CLCuD) and is transmitted by the whitefly Bemisis tabaci cryptic species. Monopartite begomoviruses encode five open reading frames (ORFs). CLCuKoV-Bur replicates through a dsDNA intermediate. Five open reading frames (ORFs) are organized in the small circular, single-stranded (ss)-DNA genome of CLCuKoV-Bur (2759 bases). RNA interference (RNAi) is a naturally occurring process that has revolutionized the targeting of gene regulation in eukaryotic organisms to combat virus infection. The aim of this study was to elucidate the potential binding attractions of cotton-genome-encoded microRNAs (Gossypium hirsutum-microRNAs, ghr-miRNAs) on CLCuKoV-Bur ssDNA-encoded mRNAs using online bioinformatics target prediction tools, RNA22, psRNATarget, RNAhybrid, and TAPIR. Using this suite of robust algorithms, the predicted repertoire of the cotton microRNA-binding landscape was determined for a CLCuKoV-Bur consensus genome sequence. Previously experimentally validated cotton (Gossypium hirsutum L.) miRNAs (n = 80) were selected from a public repository miRNA registry miRBase (v22) and hybridized in silico into the CLCuKoV-Bur genome (AM421522) coding and non-coding sequences. Of the 80 ghr-miRNAs interrogated, 18 ghr-miRNAs were identified by two to four algorithms evaluated. Among them, the ghr-miR399d (accession no. MIMAT0014350), located at coordinate 1747 in the CLCuKoV-Bur genome, was predicted by a consensus or “union” of all four algorithms and represents an optimal target for designing an artificial microRNA (amiRNA) silencing construct for in planta expression. Based on all robust predictions, an in silico ghr-miRNA-regulatory network was developed for CLCuKoV-Bur ORFs using Circos software version 0.6. These results represent the first predictions of ghr-miRNAs with the therapeutic potential for developing CLCuD resistance in upland cotton plants. Full article

Background/Objectives: BuZhong Yiqi Formula (BZYQF) has significant ameliorative effects on type 2 diabetes mellitus (T2DM). However, its efficacy in alleviating the hyposalivation caused by T2DM needs to be confirmed, and its mechanism is unclear. Methods: Network pharmacology and molecular docking were combined to analyze the molecular mechanism by which BZYQF alleviates T2DM-caused hyposalivation. A T2DM rat model was induced to evaluate the efficacy of BZYQF. The total saliva before and after acid stimulation was collected to determine the salivary flow rate and salivary alpha-amylase (sAA) activity. The parotid (PG) and submandibular glands (SMG) of experimental rats were removed to perform histopathology observation, biochemical indicator determination, and expression detection of signaling molecules in the salivary secretion pathway. Results: The present study screened out 1014 potential targets of BZYQF regarding the treatment of T2DM. These targets were mainly involved in the formation of the receptor complex, exercising the neurotransmitter receptor activity and regulating secretion. They were significantly enriched in the salivary secretion pathway of β1-AR/PKA/AMY1 and CHRM3/IP3R/AQP5. Furthermore, in BZYQF, nine validated compounds were able to dock into the active site of β1-AR, and three validated compounds were able to dock into the active site of CHRM3. Animal experiments confirmed that BZYQF significantly reduces fasting blood glucose, total cholesterol and triglyceride levels; enhances insulin level and HOMA-IS (p < 0.05); and increases salivary flow rate (Basal: increase from 21.04 ± 14.31 to 42.65 ± 8.84 μL/min, effect size of Cohen’s d = 6.80, p = 0.0078; Stimulated: increase from 36.88 ± 17.48 to 72.63 ± 17.67 μL/min, effect size of Cohen’s d = 7.61, p = 0.0025) and sAA activity (Basal: increase from 0.68 ± 0.32 to 2.17 ± 0.77 U/mL, effect size of Cohen’s d = 9.49, p = 0.0027; Stimulated: increase from 1.15 ± 0.77 to 4.80 ± 1.26 U/mL, effect size of Cohen’s d = 13.10, p = 0.0001) in basal and stimulated saliva in T2DM rats. Further mechanistic studies revealed that BZYQF reduces glucose and lipid accumulation, enhances acetylcholine content, improves pathological lesions and inflammation, and significantly increases the expression of salivary secretion pathway signaling molecules, including PKA, IP3R, β1-AR, AQP5, CHRM3, and AMY1 in the PG and SMG of T2DM rats (p < 0.05). Conclusions: The present study demonstrated that BZYQF is able to alleviate T2DM-caused hyposalivation by improving glucose metabolism and activating the salivary secretion pathway in the PG and SMG of T2DM rats. This study might provide a novel rationale and treatment strategy for BZYQF in diabetes-induced hyposalivation in a clinical setting. Full article

Background: Arterial thrombosis (AT), the main clinical manifestations of which are ischemic heart disease (IHD) and ischemic stroke (IS), is associated with lowered free triiodothyronine (fT3) in acute ischemic stroke (aIS) and acute myocardial infarction (aMI) but increased reverse T3 (rT3) in aMI, which are associated with worse outcomes at one year. Whether such associations remain independent over a longer follow-up period and the value of rT3 in aIS outcomes are largely unknown. This study was dedicated to examining the impact of fT3 and rT3 on aIS and aMI all-cause mortality over a longer 5-year period. Methods: Individuals from Lithuania who experienced aIS and aIM were included in this study. Serum fT3, rT3, free thyroxin and thyroid-stimulating hormone values were examined on admission to the intensive care department. Follow-up for all-cause mortality was divided into two time periods: 1 and 5 years. Results: The final study (aIS cohort age, 67.5 ± 9.6 years, 41.5% women and aMI cohort age, 61.8 ± 11.4 years, 28% women) consisted of 241 aIS and 289 aMI individuals, respectively. Lower fT3 was independently associated (OR = 0.41; 95% CI: 0.17–0.99, p = 0.049) with aIS, and higher rT3 (OR = 1.69; 95% CI: 1.06–2.67, p = 0.027) with aMI with increased all-cause mortality at 1 year. No associations were found between studied hormones and all-cause mortality at 5 years in both conditions. Conclusions: Lower fT3 in aIS and higher rT3 in aMI are associated with higher all-cause mortality at 1 year. No such associations were found at 5 years. Full article

Background/Objectives: Acute myocardial infarction (AMI) is a critical medical condition that requires immediate attention to minimise heart damage and improve survival rates. Early identification and prompt treatment are essential to save the patient’s life. Currently, the treatment strategy focuses on restoring blood flow to the myocardium as quickly as possible. However, reperfusion activates several cellular cascades that contribute to organ dysfunction, resulting in the ischaemia/reperfusion (I/R) injury. The search for treatments against AMI and I/R injury is urgent due to the shortage of effective treatments at present. In this regard, histone deacetylase (HDAC) inhibitors emerge as a promising treatment against myocardial infarction. The objective of this systematic review is to analyse the effects of HDAC inhibitors on ventricular function, cardiac remodelling and infarct size, among other parameters, focusing on the signalling pathways that may mediate these cardiovascular effects and protect against AMI. Methods: Original experimental studies examining the effects of HDAC inhibitors on AMI were included in the review using the PubMed and Scopus databases. Non-experimental papers were excluded. The SYRCLE RoB tool was used to assess risk of bias and the results were summarised in a table and presented in sections according to the type of HDAC inhibitor used. Results: A total of 18 studies were included, 10 of them using trichostatin A (TSA) as an HDAC inhibitor and concluding that the treatment improved ventricular function, reduced infarct size, and inhibited myocardial hypertrophy and remodelling after AMI. Other HDAC inhibitors, such as suberoylanilide hydroxamic acid (SAHA), valproic acid (VPA), mocetinostat, givinostat, entinostat, apicidin, and RGFP966, were also analysed, showing antioxidant and anti-inflammatory effects, an improvement in cardiac function and remodelling, and a decrease in apoptosis, among other effects. Conclusions: HDAC inhibitors constitute a significant promise for the treatment of AMI due to their diverse cardioprotective effects. However, high risk of selection, performance, and detection bias in the in vivo studies means that their application in the clinical setting is still a long way off and more research is needed to better understand their benefits and possible side effects.

The purpose of this study is to characterize the ocular surface microbiota of patients with an anophthalmic cavity. An eNAT with 1 mL of Liquid Amies Medium was used to collect samples. Microbial DNA from anophthalmic socket and healthy fellow control eye samples was isolated and sequenced. Raw reads were analyzed with GAIA (v 2.02). The richness and Shannon alpha diversity metrics, as well as Bray–Curtis beta diversity and Wilcoxon signed-rank test values, were computed with R packages such as phyloseq, mia, or DESeq2 to allow for microbiome analysis. Principal coordinate analysis (PCoA) was performed using the function plotReducedDim from the R package scater. The different taxonomic profiles were described under the concept of eye community state type (ECST). The microbiomes of both eyes from 25 patients with an anophthalmic cavity were analyzed in this study. While the microbial communities of paired eyes from the same patients showed notable dissimilarity, no consistent patterns emerged when comparing healthy eyes to anophthalmic sockets. Alpha diversity values did not significantly differ between healthy eyes and anophthalmic socket samples, though there was considerable variability within each group. Notably, anophthalmic socket samples generally exhibited lower abundances of genera such as Staphylococcus, Enterococcus, Paenibacillus, and Sediminibacterium compared to their healthy counterparts. Microbial variability between healthy eyes and anophthalmic sockets may be due to anatomical differences. Further research is needed to determine whether patients without anophthalmic sockets exhibit similar microbiome patterns in both eyes. Full article
