An optimised faecal microRNA sequencing pipeline reveals fibrosis in Trichuris muris infection.

The intestine is a site of diverse functions including digestion, nutrient absorption, immune surveillance, and microbial symbiosis. Intestinal microRNAs (miRNAs) are detectable in faeces and regulate barrier integrity, host-microbe interactions and the immune response, potentially offering valuable non-invasive tools to study intestinal health. However, current experimental methods are suboptimal and heterogeneity in study design limits the utility of faecal miRNA data.

Electrocatalysis: From Planar Surfaces to Nanostructured Interfaces.

The reactions critical for the energy transition center on the chemistry of hydrogen, oxygen, carbon, and the heterogeneous catalyst surfaces that make up electrochemical energy conversion systems. Together, the surface-adsorbate interactions constitute the electrochemical interphase and define reaction kinetics of many clean energy technologies. Practical devices introduce high levels of complexity where surface roughness, structure, composition, and morphology combine with electrolyte, pH, diffusion, and system level limitations to challenge our ability to deconvolute underlying phenomena.

KLF13 promotes SLE pathogenesis by modifying chromatin accessibility of key proinflammatory cytokine genes.

Although significant progress has been achieved in elucidating the genetic architecture of systemic lupus erythematosus (SLE), identifying genes underlying the pathogenesis has been challenging. The NZM2410-derived lupus susceptibility Sle3 locus is associated with T cell hyperactivity and activated myeloid cells. However, candidate genes associated with these phenotypes have not been identified.

Role of Transition Metals in Pt Alloy Catalysts for the Oxygen Reduction Reaction.

In pursuit of higher activity and stability of electrocatalysts toward the oxygen reduction reaction, it has become standard practice to alloy platinum in various structural configurations. Transition metals have been extensively studied for their ability to tune catalyst functionality through strain, ligand, and ensemble effects. The origin of these effects and potential for synergistic application in practical materials have been the subject of many theoretical and experimental analyses in recent years.

Platelet TLR7 is essential for the formation of platelet-neutrophil complexes and low-density neutrophils in lupus nephritis.

Objectives: Platelets and low-density neutrophils (LDNs) are major players in the immunopathogenesis of SLE. Despite evidence showing the importance of platelet-neutrophil complexes (PNCs) in inflammation, little is known about the relationship between LDNs and platelets in SLE. We sought to characterize the role of LDNs and Toll-like receptor 7 (TLR7) in clinical disease.
