After a 3-month rhGH washout, 9 confirmed TGHD patients (diagnosed per 2019 AACE criteria) were stratified into treatment (n = 4, rhGH continuation) and non-treatment (n = 5) groups.

BACE2-Induced Aberrant Lymphatic Network Aggravates the Local Inflammation in Arteriovenous Fistulas With Hyperphosphatemia.

As a widely used vascular access for hemodialysis patients, arteriovenous fistula (AVF) still faces high failure rates, in which local inflammatory response is an essential factor. In animal studies, chronic kidney disease (CKD) has been reported to aggravate local inflammation in AVFs, but the mechanisms are controversial. Here, spatial transcriptomics and single-cell RNA sequencing are used to explore the cellular changes during AVF remodeling in human and mouse.

PIEZO1-activated donor lymphatic remodeling integrates with autologous lymphangiogenesis to enhance vein graft patency in mice.

The great saphenous vein is the most commonly used conduit in coronary artery bypass grafting; however, the high vein graft failure rates remain an unresolved issue. Here, we compared different harvesting techniques for mouse vein grafts and found that the construction of a denser lymphatic network contributed to improved vein graft patency. Dual lymphatic tracing strategies using -Cre;R26-tdTomato/zsGreen mice uncovered a heterogeneous lymphatic network in mouse vein grafts.

Diet has emerged as a key impact factor for gut microbiota function. However, the complexity of dietary components makes it difficult to predict specific outcomes. Here we investigate the impact of plant-derived nanoparticles (PNP) on gut microbiota and metabolites in context of cancer immunotherapy with the humanized gnotobiotic mouse model.

Endothelial TRIM35-Regulated MMP10 Release Exacerbates Calcification of Vascular Grafts.

Vascular calcification is a highly regulated process in cardiovascular disease (CVD) and is strongly correlated with morbidity and mortality, especially in the adverse stage of vascular remodeling after coronary artery bypass graft surgery (CABG). However, the pathogenesis of vascular graft calcification, particularly the role of endothelial-smooth muscle cell interaction, is still unclear. To test how ECs interact with SMCs in artery grafts, single-cell analysis of wild-type mice is first performed using an arterial isograft mouse model and found robust cytokine-mediated signaling pathway activation and SMC proliferation, together with upregulated endothelial tripartite motif 35 (TRIM35) expression.

Ultrasensitive detection of microRNAs based on cascade amplification strategy of RCA-PER and Cas12a.

Since microRNAs (miRNAs) serve as markers for early cancer diagnosis, it is crucial to develop a novel biosensor to detect miRNAs quickly, sensitively and selectively. Hence, we developed a fluorescence biosensor based on target miRNA-initiated rolling circle amplification (RCA) to generate RCA products with multiple tandem catalytic hairpin DNA templates that trigger primer exchange reactions (PER) which extend short single-strand DNA (ssDNA) primers into long ssDNA. Subsequently, the long ssDNA activates the -cleavage activity of the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas12a system to cleave a fluorescent reporter chain, enabling ultrasensitive detection of miRNAs through the output fluorescence signal.

The changes of cell subsets in lower limb ischemia samples were detected by single-cell RNA sequencing.

Smart Janus cotton fabrics prepared via mist polymerization for moisture and thermal management.

The construction of Janus structures on cotton fabrics can endow the fabrics with dynamic multifunctional properties. However, because of the large pores between fabric fibers, the formation of Janus structures by grafting different functional coatings on the double surfaces of cotton fabrics via dipping technology is difficult. To construct Janus structures on cotton fabrics, mist polymerization and "grafting-through" polymerization technologies were used to graft polylauryl methacrylate and a heat-shrinkable thermosensitive antibacterial polymer on the inside and outside surfaces of the cotton fabric, respectively.
