Article Abstract
Diabetes mellitus is a major health problem across the world. Diabetic retinopathy (DR) and nephropathy are two of the major complications of diabetes. DR is the leading cause of blindness and diabetic nephropathy is the leading cause of end-stage renal failure. We have examined the potential value of circulating nucleic acids in the detection and monitoring of these two complications of diabetes. mRNA for nephrin was significantly higher in all diabetics compared to healthy controls and it was significantly higher in normoalbuminuric patients compared to healthy controls. This may indicate progression to microalbuminuric stage. Circulating rhodopsin mRNA was detectable in healthy subjects and in diabetic patients. It was significantly raised in diabetic patients with retinopathy. Higher rhodopsin mRNA in diabetic patients without retinopathy suggests that some of them may go on to develop it or already have it subclinically. Circulating nucleic acids have the potential to be noninvasive molecular tests for diabetic complications.

Nanobodies are promising for immunoPET imaging due to their excellent antigen recognition and tumor targeting, yet rapid clearance limits their tumor accumulation. Although multimerization and albumin binding can extend their circulation time and improve tumor targeting, a simple and universal method for creating protein multimers is still needed. Here, we leveraged the facile synthesis, controllable size, and precise assembly of DNA nanotechnology to construct CD47-targeted framework nucleic acid-nanobody fusion probes with multiple valences and sizes.

Platelets are nucleic-free cells with a lifespan of 7-10 days in the bloodstream, playing a crucial role in various physiological processes such as hemostasis, thrombus formation, tumor development and metastasis, inflammation, and host defense. By utilizing the unique structural and functional characteristics of platelets, platelet-modified nano-drugs can evade immune recognition and clearance and facilitate prolonged circulation , which ultimately allows the nanoparticles to reach sites of disease such as thrombi, tumors, inflammation, or bacterial infections, leading to specific adhesion and significantly enhancing the efficiency of targeted drug delivery. This paper reviews the novel design and application of platelet-derived biomaterials in various diseases in recent years and comprehensively demonstrates the potential of platelet-derived biomaterials in the fields of disease therapy and biodefence, which will provide a reference for advancing the development of platelet-derived biomaterials and clinical practice.

Fibroblast activation protein (FAP) is an important antigen in the tumor microenvironment, which plays a crucial role in promoting extracellular matrix remodeling and tumor cell metastasis. A circulating form of soluble FAP has also been identified in the serum, becoming a biomarker for pan-cancer diagnosis and prognosis. However, the current peptide substrate-based enzymatic activity detection or antibody-dependent detection methods have been hindered by insufficient selectivity and complex operations, so it is valuable to develop effective nucleic acid aptamers as FAP affinity ligands.

Acute respiratory tract infections (ARTIs) are among the leading causes of morbidity and mortality in children worldwide. Human adenovirus (HAdV) infections are estimated to account for at least 5% of pediatric ARTIs. The circulated genotypes of HAdV and the correlation between genotype and clinical manifestations in Wuhan, China, before and after the complete relaxation of nonpharmaceutical interventions against severe acute respiratory syndrome coronavirus 2, remain unknown.

Serum HBV-RNA (seRNA) was proposed to be a circulating marker of cccDNA transcriptional activity in hepatocytes. The combination of tenofovir-disoproxil-fumarate (TDF) and pegylated-interferon-alpha-2a (pegIFN) with nucleic-acid polymer (NAP) treatment was associated with a relatively high rate of functional cure (FC) 48 weeks after discontinuation of all therapy. We aim to characterize seRNA kinetics under TDF and pegIFN±NAP combination therapies.
