Sea buckthorn berries alleviate ulcerative colitis via regulating gut Faecalibaculum rodentium-mediated butyrate biosynthesis.

Background: The gut microbiota is firmly associated with the progression of ulcerative colitis (UC). Beneficial microbial metabolites, such as butyrate, exert vital roles in maintaining intestinal homeostasis. The Sea buckthorn berry is a traditional Chinese medicine homologous to food and medicine which is widely applied in the prevention and treatment of UC in clinic practice.

Early detection of Parkinson's disease through multiplex blood and urine biomarkers prior to clinical diagnosis.

Blood and urine biomarkers are commonly used to diagnose and monitor chronic diseases. We initially screened 67 biomarkers, including 4 urine biomarkers and 63 blood biomarkers, and identified 13 blood biomarkers significantly associated with Parkinson's disease (PD). Among these, we discovered three novel markers demonstrating strong associations: phosphate (P = 1.

Niche-driven phenotypic plasticity and cis-regulatory dynamics of a revised model for intestinal secretory differentiation.

Enterocytes and four secretory cell types derive from stem cells located in intestinal crypts. Whereas secretory goblet and Paneth cells have long been considered distinct, we find high overlap in their transcripts and sites of accessible chromatin, in marked contrast to those of sibling enteroendocrine or tuft cells. Mouse and human goblet and Paneth cells express extraordinary fractions of selective antimicrobial genes, reflecting specific and variable gene responses to local niche signals.

Single-cell atlas of human pancreatic islet and acinar endothelial cells in health and diabetes.

Characterization of the vascular heterogeneity within the pancreas has previously been lacking. Here, we develop strategies to enrich islet-specific endothelial cells (ISECs) and acinar-specific endothelial cells (ASECs) from three human pancreases and corroborate these findings with three published pancreatic datasets. Single-cell RNA sequencing reveals the unique molecular signatures of ISECs, including structural genes COL13A1, ESM1, PLVAP, UNC5B, and LAMA4, angiocrine genes KDR, THBS1, BMPs and CXCR4, and metabolic genes ACE, PASK and F2RL3.

Hydrochar-nanocomposite membrane combined hydrothermal pretreatment for nutrient upcycling from anaerobic digestate.

Efficient resource recovery is crucial for sustaining food production and alleviating stress on ecosystems. This study combines hydrothermal pretreatment with polyvinylidene fluoride (PVDF)-hydrochar nanocomposite membranes for near-complete resource recovery in kitchen waste treatment. The dual-functionalized pretreatment, which combines targeted conversion/enrichment with adsorption/filtration, effectively addresses the limitations of existing membrane separation technologies, including low nutrient recovery selectivity, low flux, and high costs.

[Improvement of catalytic activity and thermostability of glucose oxidase from ].

Glucose oxidase (GOD) is an oxygen-consuming dehydrogenase that can catalyze the production of gluconic acid hydrogen peroxide from glucose, and its specific mechanism of action makes it promising for applications, while the low catalytic activity and poor thermostability have become the main factors limiting the industrial application of this enzyme. In this study, we used the glucose oxidase GOD reported with the best thermostability as the source sequence for phylogenetic analysis to obtain the GOD with excellent performance. Six genes were screened and successfully synthesized for functional validation.

Deciphering hub genes and immune landscapes related to neutrophil extracellular traps in rheumatoid arthritis: insights from integrated bioinformatics analyses and experiments.

Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by synovial inflammation and progressive joint destruction. Neutrophil extracellular traps (NETs), a microreticular structure formed after neutrophil death, have recently been implicated in RA pathogenesis and pathological mechanisms. However, the underlying molecular mechanisms and key genes involved in NET formation in RA remain largely unknown.

Three-dimensional sonographic findings of diprosopus: a case report and literature review.

Background: Diprosopus is one of the rarest anomalies. It typically manifests as bilateral alterations and often involves anomalies within the cranial structures. In this report, we present a case of a fetus with diprosopus diagnosed prenatally.

Unravelling the TCRβ repertoire: a key to unlocking the immunopathogenesis and precision medicine in SLE.

Objectives: SLE is a multifaceted autoimmune disorder with a complex pathogenesis involving genetic, environmental and hormonal factors, which converge on immune dysregulation. The T cell receptor (TCR) repertoire's role in SLE has garnered significant interest due to its potential in both diagnostics and therapeutics. Our study aimed to delineate the variances in the TCRβ repertoire between patients with SLE and healthy individuals, correlating these differences with the severity and subtypes of SLE.

Inflammation-induced Generation of Splenic Erythroblast-like Ter- Cells Inhibits the Progression of Acute Lung Injury via Artemin.

Identifying inflammation-induced leukocyte subsets and their derived circulating factors has been instrumental in understanding the progession of ALI/ARDS. Nevertheless, how primary inflammation-induced non-leukocyte populations in distal organs contribute to ALI/ARDS remains poorly defined. Here, we report one population of erythroblast-like cells (Ter-cells) deriving from megakaryocyte- erythroid progenitor cells with a unique Ter-119+CD45-CD71+ phenotype in ALI/ARDS.

Prediction of pulmonary embolism by an explainable machine learning approach in the real world.

In recent years, large amounts of researches showed that pulmonary embolism (PE) has become a common disease, and PE remains a clinical challenge because of its high mortality, high disability, high missed and high misdiagnosed rates. To address this, we employed an artificial intelligence-based machine learning algorithm (MLA) to construct a robust predictive model for PE. We retrospectively analyzed 1480 suspected PE patients hospitalized in West China Hospital of Sichuan University between May 2015 and April 2020.

Depletion of regulatory T cells enhances the T cell response induced by the neoantigen vaccine with weak immunogenicity.

Background: The neoantigen vaccine has remarkable potential in treating advanced cancer due to its tumor specificity and ability to bypass central tolerance mechanisms. However, numerous neoantigens show poor immunogenicity, and the immune inhibitory factors of present in both tumors and tumor-draining lymph nodes impair the efficacy of cancer neoantigen vaccine. Eliminating immunosuppressive cells will improve the priming and expansion of anti-tumor immune cells induced by the vaccine.

A primary intracranial neuroepithelial neoplasm with novel TCF3::BEND2 fusion: a case report.

Astroblastoma, MN1-altered, is a rare circumscribed glial neoplasm that is composed of round, cuboidal, orcolumnar cells with astroblastic perivascular pseudorosettes, often associated with MN1::BEND2 and MN1::CXXC5 fusions. Atroblastoma-like gliomas harbouring EWSR1::BEND2 have been reported that they defined an epigenetically distinct subtype of astroblastoma. We report a case of a 19-year-old female with an intracranial neuroepithelial tumor featuring a novel TCF3::BEND2 fusion.

DOT1L protects against podocyte injury in diabetic kidney disease through phospholipase C-like 1.

Background: Podocyte injury causes proteinuria and accelerates glomerular sclerosis during diabetic kidney disease (DKD). Disruptor of telomeric silencing 1-like (DOT1L), an evolutionarily conserved histone methyltransferase, has been reported in preventing kidney fibrosis in chronic kidney disease models. However, whether DOT1L exerts beneficial effects in diabetes induced podocyte injury and the underlying molecular mechanisms need further exploration.

Jianpi qingre tongluo prescription alleviates the senescence-associated secretory phenotype with osteoarthritis by regulating STAG1/TP53/P21 signaling pathway.

Ethnopharmacological Relevance: Jianpi Qingre Chubi prescription primarily consists of a compound formula, also known as Huangqin Qingre Chubi Capsules (HQC), which strengthens the spleen and resolves dampness, clear heat, and collaterals. Long-term clinical use has shown that HQC improves joint swelling and pain in patients with osteoarthritis. Mechanistically, we demonstrated that HQC inhibits inflammatory responses, extracellular matrix degradation, and delays chondrocyte senescence.
