Alternative antibody (aptamer)-based biosensors are attracting increasing attention owing to advantages such as simplicity and low cost, which are beneficial for point-of-care diagnosis, particularly where resources are limited. In this study based on in silico modeling predictions made with Autodock Vina, the binding affinity of an optimized novel peptide (Pf_P1: KITTTDEEVEGIFD) was altered compared to that of the original epitope peptide (P1: KITDEEVEGIFDC). The binding energy of Pf_P1 implies that it has stronger interactions with Plasmodium falciparum lactate dehydrogenase (LDH) than with human LDH...

Skin undergoes photoaging, typically characterized by UV-damage lesions with matrix degradation and inflammatory changes. This process involves Hedgehog (Hh) signaling and the canonical Wnt pathway. Recently, primary cilia-microtubule-based organelles-have been implicated in the transduction of Hh and Wnt signaling. However, their role in photoaging remained unclear. In this study, we have shown that UVB causes both upregulation of MMPs and proinflammatory cytokines, as well as cilia formation in HaCaT cells, and that these changes can be attenuated by ciliogenesis inhibitor HPI-4 and anti-inflammatory PD98059 treatment...

Transferring nucleic acids into mammalian cells heavily influences life science for decades. While first applications mainly dealt with DNA transfer for various purposes as e.g., plasmid encoded protein expression or generation of mutant strains, subsequent applications additionally transferred RNA molecules of mainly small lengths for specific knockdown (RNAi) or site-specific genome modification (gRNA). Significant improvements in full length mRNA generation and extension of mRNA lifetimes additionally allows their use for transient expression in latest times...

This paper models the acoustic drug release of chemotherapeutics from liposomes using a kinetic model that accounts for systematic biases affecting the drug delivery process. An optimal stochastic filter is then proposed to provide robust estimates of the percent drug released. Optimality is guaranteed by accurately identifying the underlying statistical noise characteristics in experimental data. The estimator also quantifies the bias in the release, exhibited by the experimental data. Drug release is experimentally measured as a change in fluorescence upon the application of ultrasound...

Baicalin (BA) has gained considerable attention in recent years for its multiple pharmacological activities. However, its optimum pharmaceutical potential has been limited by its poor solubility in water. In this study, for the first time, we discovered that novel water-soluble carbon dots (CDs, named RPC-CDs) from aqueous extracts of Radix Puerariae Carbonisata (RPC). The chemical composition and morphological features of the RPC-CDs we obtained were characterized using various spectroscopies and transmission electron microscopy and the CDs have a low toxicity against RAW 264...

Targeting tumor-associated macrophages (TAMs) has emerged as a novel therapeutic strategy for cancer metastasis. Here, we investigated whether carboxylated multiwalled carbon nanotubes (MWCNTs-COOH) prevent tumor metastasis through regulating macrophage polarization. In Lewis lung carcinoma (LLC) or B16F10 melanoma-bearing mice, intratracheal instillation of MWCNTs-COOH significantly reduced metastatic burden in the lungs. MWCNTs-COOH promoted the expression of M1 markers (iNOS and CXCR10) and inhibited the expression of M2 markers (CD206 and Arg-1) along with an increased expression of Th1 cytokines (TNF- α and IL-12) and decreased expression of Th2 cytokines (TGF- β and IL-10)...

RNA interference (RNAi) plays important roles, and microRNAs (miRNAs) are used as biomarkers and targets in cell therapies. In this study, we fabricated miRNAs and short hairpin RNAs (shRNAs) targeting the osteogenic RUNX2 gene to induce chondrogenesis of human mesenchymal stem cells (hMSCs). pDNA harboring these miRNAs and shRNAs was complexed with nanoparticles composed of dexamethasone and tetramethlyrhodamine-labeled branched polyethyleneimine (RDtNPs). The miRNAs and shRNAs reduced RUNX2 expression in hMSCs at early (12 h) and late (72 h) time points, respectively...

The vaccine delivery process plays a significant role for antigen-specific immune responses, which directly determines the effect of immunotherapy. It is crucial to reveal the real-time process of the vaccine release and the status of the implanted carrier in vivo . Herein, a dual fluorescent vaccine delivery system was monitored with the rhodamine-ovalbumin loaded zinc phthalocyanine conjugated nanoparticles (PHA-OVA NPs) to explore the vaccine delivery process. The PHA-OVA NPs showed a sustained release of ovalbumin in vitro and could significantly enhance the uptake of antigen by dendritic cells (DCs)...

For the effective inhibition of atherosclerotic plaque rupture, there is an urgent need to develop a carrier which can specifically deliver the therapeutic agents to atherosclerotic lesions. Since the representative hallmark of plaques in advanced atherosclerosis is the large number of macrophages which highly upregulate folate receptor beta (FR- β ), we herein investigated the potential of folate-modified liposomes (FA-P-LP) as the carrier for active targeting of atherosclerotic plaques. In vitro cellular uptake tests, FA-P-LP exhibited an enhanced uptake in activated RAW264...
