Abstract
OBJECTIVE Osteonecrosis of the femoral head (ONFH) is a severe disease that primarily affects the middle-aged population, imposing a significant economic and social burden. Recent research has linked the progression of non-traumatic osteonecrosis of the femoral head (NONFH) to the composition of the gut microbiota. Steroids and alcohol are considered major contributing factors. However, the relationship between NONFH caused by two etiologies and the microbiota remains unclear. In this study, we examined the gut microbiota and fecal metabolic phenotypes of two groups of patients, and analyzed potential differences in the pathogenic mechanisms from both the microbial and metabolic perspectives. METHODS Utilizing fecal samples from 68 NONFH patients (32 steroid-induced, 36 alcohol-induced), high-throughput 16 S rDNA sequencing and liquid chromatography with tandem mass spectrometry (LC-MS/MS) metabolomics analyses were conducted. Univariate and multivariate analyses were applied to the omics data, employing linear discriminant analysis effect size to identify potential biomarkers. Additionally, functional annotation of differential metabolites and associated pathways was performed using the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. Subsequently, Spearman correlation analysis was employed to assess the potential correlations between differential gut microbiota and metabolites. RESULTS High-throughput 16 S rDNA sequencing revealed significant gut microbial differences. At the genus level, the alcohol group had higher Lactobacillus and Roseburia, while the steroid group had more Megasphaera and Akkermansia. LC-MS/MS metabolomic analysis indicates significant differences in fecal metabolites between steroid- and alcohol-induced ONFH patients. Alcohol-induced ONFH (AONFH) showed elevated levels of L-Lysine and Oxoglutaric acid, while steroid-induced ONFH(SONFH) had increased Gluconic acid and Phosphoric acid. KEGG annotation revealed 10 pathways with metabolite differences between AONFH and SONFH patients. Correlation analysis revealed the association between differential gut flora and differential metabolites. CONCLUSIONS Our results suggest that hormones and alcohol can induce changes in the gut microbiota, leading to alterations in fecal metabolites. These changes, driven by different pathways, contribute to the progression of the disease. The study opens new research directions for understanding the pathogenic mechanisms of hormone- or alcohol-induced NONFH, suggesting that differentiated preventive and therapeutic approaches may be needed for NONFH caused by different triggers.

Abstract
Concurrent effect of nanomaterials (NMs) and warming on plant performance remains largely unexplored. In this study, the effects of nanopesticide CuO and nanofertilizer CeO2 on wheat (Triticum aestivum) under optimal (22 °C) and suboptimal (30 °C) temperatures were evaluated. CuO-NPs exerted a stronger negative effect on plant root systems than CeO2-NPs at tested exposure levels. The toxicity of both NMs could be attributed to altered nutrient uptake, induced membrane damage, and raised disturbance of antioxidative related biological pathways. Warming significantly inhibited root growth, which was mainly linked to the disturbance of energy metabolism relevant biological pathways. The toxicity of NMs was enhanced upon warming, with a stronger inhibition of root growth and Fe and Mn uptake. Increasing temperature increased the accumulation of Ce upon CeO2-NP exposure, while the accumulation of Cu was not affected. The relative contribution of NMs and warming to their combined effects was evaluated by comparing disturbed biological pathways under single and multiple stressors. CuO-NPs was the dominant factor inducing toxic effects, while both CeO2-NPs and warming contributed to the mixed effect. Our study revealed the importance of carefully considering global warming as a factor in risk assessment of agricultural applications of NMs.

Abstract
Candida albicans is a predominant species causing candidemia in hospitalized patients. This study aimed to investigate the association of culture medium metabolomic profiles with biofilm formation and invasion properties of clinical bloodstream-isolated C. albicans. A total of twelve isolates and two reference strains were identified by virulent phenotypes. Their susceptibility was determined by the microdilution method, following EUCAST guidelines. Biofilm formation was evaluated with metabolic activity, morphology and agglutinin-like sequence 3 (ALS3) mRNA expression. Invasion into the vascular endothelial EA.hy926 cells was determined by lactate dehydrogenase release and internalization assay. Their metabolomic profiles were assessed by high-resolution accurate-mass spectrometry (HRAMS). The results showed four different phenotypes of C. albicans: high-biofilm/invasive (50%), high-biofilm/non-invasive (7%), low-biofilm/invasive (36%) and low-biofilm/non-invasive (7%). The metabolomic profiles of the culture medium determined strong correlation of the virulent phenotypes and the alteration of metabolites in the methionine metabolism pathway, such as homocysteine, 5-methyltetrahydrofolate and S-adenosylmethioninamine. Moreover, thiamine and biotin levels were significantly increased in Isolate03, representative of a high-biofilm/invasive phenotype. These results suggest that methionine and vitamin B metabolism pathways might be influenced by their virulent phenotypes and pathogenic traits. Therefore, their metabolism pathways might be a potential target for reducing virulence of C. albicans bloodstream infections.

Abstract
Human-induced pluripotent stem cells (h-iPSCs) are a unique in vitro model for cardiovascular research. To realize the potential applications of h-iPSCs-derived cardiomyocytes (CMs) for drug testing or regenerative medicine and disease modeling, characterization of the metabolic features is critical. Here, we show the transcriptional profile during stages of cardiomyogenesis of h-iPSCs-derived CMs. CM differentiation was not only characterized by the expression of mature structural components (MLC2v, MYH7) but also accompanied by a significant increase in mature metabolic gene expression and activity. Our data revealed a distinct substrate switch from glucose to fatty acids utilization for ATP production. Basal respiration and respiratory capacity in 9 days h-iPSCs-derived CMs were glycolysis-dependent with a shift towards a more oxidative metabolic phenotype at 14 and 28 day old CMs. Furthermore, mitochondrial analysis characterized the early and mature forms of mitochondria during cardiomyogenesis. These results suggest that changes in cellular metabolic phenotype are accompanied by increased O2 consumption and ATP synthesis to fulfill the metabolic needs of mature CMs activity. To further determine functionality, the physiological response of h-iPSCs-derived CMs to β-adrenergic stimulation was tested. These data provide a unique in vitro human heart model for the understanding of CM physiology and metabolic function which may provide useful insight into metabolic diseases as well as novel therapeutic options.
