Abstract Background Equine Metabolic Syndrome (EMS) is a multifactorial endocrine disorder characterized by obesity, insulin dysregulation (ID), and an increase in the risk of laminitis, painful condition that can lead to euthanasia severe cases. Diagnosing EMS challenging often relies on clinical history including difficulty losing weight, recurring episodes laminitis. The gold standard for laboratory support diagnosis identification ID, being basal simplest most accessible method. However, various factors such as diet, age, stress, season, testing protocols influence results. Dynamic tests like oral sugar test (OST) are preferred but present limitations due low sensitivity poor repeatability. These diagnostic challenges make difficult detect veterinary medicine highlighting need effective method early detection prevent laminitis its associated complications. Results Mass spectrometry-based proteomics represents powerful tool identify biomarkers explore molecular pathways related underlying pathology. In current study we established integrated pipeline plasma diagnosis. We compared proteomes from healthy horses, non-ID obese horses animals diagnosed with EMS. This comparison revealed 76 proteins significant changes (1% FDR) between groups. Conclusions Our demonstrates complement system, coagulation cascade extracellular matrix remodelling altered findings offer new insights into basis development led nomination several potential detection.

DNA nanotechnology has emerged as a powerful approach to engineering biophysical tools, therapeutics, and diagnostics because it enables the construction of designer nanoscale structures with high programmability. Based on base pairing rules, nanostructure size, shape, surface functionality, structural reconfiguration can be programmed degree spatial, temporal, energetic precision that is difficult achieve other methods. However, properties structure constructs are greatly altered in vivo due spontaneous protein adsorption from biofluids. These adsorbed proteins, referred corona, remain challenging control or predict, subsequently, their functionality fate engineer. To address these challenges, we prepared library diverse nanostructures investigated relationship between design features composition corona. We identified characteristics important for developed machine-learning model predicts which proteins will enriched based structures' properties. Our work help understand program function biomedical applications.

Women are at significantly greater risk of metabolic dysfunction after menopause, which subsequently leads to numerous chronic illnesses. The gut microbiome is associated with obesity and dysfunction, but its interaction female sex hormone status the resulting impact on host metabolism remains unclear. Herein, we characterized inflammatory phenotypes as well ovariectomy high-fat diet feeding, compared gonadal intact low-fat controls. We then performed fecal microbiota transplantation (FMT) using gnotobiotic mice identify ovariectomy-associated outcomes. demonstrated that led gastrointestinal permeability inflammation organs, a exacerbated these phenotypes. Ovariectomy also alteration microbiome, including β-glucuronidase activity. However, differential changes in only occurred when fed diet, not diet. Gnotobiotic received from ovariectomized had weight gain hepatic gene expression related than those sham control-associated microbiome. These results indicate responds alterations contributes dysfunction. Identifying developing microbiome-targeted modulators regulate hormones may be useful therapeutically remediating menopause-related diseases.
