Traditional RCA methods face some drawbacks including limited specificity and amplification templates with sequence dependence. Herein, a universal RCA (URCA) strategy for label-free nucleic acid sensing with high specificity was proposed, which could be used for sensing of different nucleic acids without redesigning or synthesizing new amplification templates. The URCA strategy also showed high accuracy for miRNA analysis in practical samples.

Non-alcoholic fatty liver disease (NAFLD) is a disease with various levels varying from fatty liver steatosis to acute steatosis which is non-alcoholic steatohepatitis (NASH), which can develop into hepatic failure, as well as in some conditions it can develop into hepatocellular carcinoma (HCC). In the NAFLD and NASH context, aberrant microRNA (miRNA) expression has a thorough contribution to the incidence and development of these liver disorders by influencing key biological actions, involving lipid metabolism, inflammation, and fibrosis. Dysregulated miRNAs can disrupt the balance between lipid accumulation and clearance, exacerbate inflammatory responses, and promote fibrogenesis, thus advancing the severeness of the disorder from simple steatosis to more complex NASH.

Background: Wolbachia is an endosymbiont bacterium known to stimulate host immunity against arboviruses and protozoa. Côte d'Ivoire is in a malaria-endemic region, and has experienced several dengue epidemics in recent decades as well. In order to help reduce the transmission of pathogens by mosquito vectors, we studied the prevalence of Wolbachia and the distribution of Cytoplasmic incompatibility factors (Cif) genes in different mosquito species caught in the wild in Cote d'Ivoire.

Ternary heterojunction BiS/MoS/BiMoO was designed as a signal probe to develop a dual signal amplification strategy empowered electrochemical biosensor for sensitive miRNA-21 detection by combining with catalytic hairpin assembly (CHA). The combination of the BiS/MoS/BiMoO heterojunction as a tracer indication probe and the CHA amplification strategy not only took fully use of the highly dense nanowire interwoven structure and superior active region of the probe, but also endowed the ability to improve the molecular hybridization efficiency by collision, which significantly avoided the cumbersome chain design and greatly simplified the step-by-step construction of the electrode surface. Hairpin H1 was first added dropwise to the gold nanoparticle-decorated electrode surface, and then opened by the introduced miRNA-21 to initiate the specific hybridization.

Purpose: microRNA-371a-3p (M371) is considered a highly sensitive and specific serum biomarker of testicular germ cell tumours (GCTs). However, little is known about the expression of M371 in nontesticular malignancies (NTMs), so far. As knowledge about the expression of the marker in other malignancies is a prerequisite for the clinical application of the test we aimed to explore the M371 expression in other cancers.
