Abstract Genetically encoded fluorescent biosensors allow intracellular signaling dynamics to be tracked in live cells and tissues using optical detection. Many such biosensors are based on the principle of Forster resonance energy transfer (FRET), and we have recently developed a simple approach for in vivo detection of FRET-based biosensor signals using fiber photometry. By combining fiber photometry with FRET-based biosensors, we were able to track GPCR-dependent signaling pathways over time,...

Abstract Pseudourine (Ψ) is the most abundant cellular RNA modification, present in tRNA, rRNA, snRNA, mRNA, long noncoding RNA (lncRNA), and others. Ψ sites and fractions are dynamically regulated in stress response and across development stages. Although high throughput Ψ sequencing methods based on N-Cyclohexyl-N’-(2-morpholinoethyl)carbodiimide (CMC) reaction are available for Ψ detection transcriptome-wide, a simple method for the analysis of specific, targeted Ψ sites and their fraction qu...

Abstract Most proteins in proteomes are large, typically consist of more than one domain and are structurally complex. This often makes studying their mechanical unfolding pathways challenging. Proteins composed of tandem repeat domains are a subgroup of multi-domain proteins that, when stretched, display a saw-tooth pattern in their mechanical unfolding force extension profiles due to their repetitive structure. However, the assignment of force peaks to specific repeats undergoing mechanical un...

Droplet digital PCR is an innovative and promising approach for highly sensitive quantification of nucleic acids that is being increasingly used in the field of clinical virology, including the setting of hepatitis B virus (HBV). Here, we comprehensively report a robust and reproducible ddPCR assay for the highly sensitive quantification of serum HBV-DNA. The assay showed a limit of detection of 4 copies/ml (<1IU/ml) by Probit analysis, showed a good linearity (R2=0.94) and a high intra- and int...

Abstract The suppression of artifact noise in computed tomography (CT) with a low-dose scan protocol is challenging. Conventional statistical iterative algorithms can improve reconstruction but cannot substantially eliminate large streaks and strong noise elements. In this paper, we present a 3D cascaded ResUnet neural network (Ca-ResUnet) strategy with modified noise power spectrum loss for reducing artifact noise in low-dose CT imaging. The imaging workflow consists of four components. The fir...

Abstract Development of nanocarriers has opened new avenues for the delivery of therapeutics of various pharmacological activities with improved targeting properties and reduced side effects. Niosomes, non-ionic-based vesicles, have drawn much interest in various biomedical applications, owing to their unique characteristics and their ability to encapsulate both hydrophilic and lipophilic cargoes. Niosomes share structural similarity with liposomes while overcoming limitations associated with st...

Abstract Construction of nanocarriers of different structures and properties have shown great promise as delivery systems for a wide range of drugs to improve therapeutic effects and reduce side effects. Nanostructured lipid carriers (NLCs) have been introduced as a new generation of solid lipid nanoparticles (SLNs) to overcome several of the limitations associated with the SLNs. NLCs consist of a blend of solid and liquid lipids which result in a partially crystallized lipid system that enables...

With the advance of deep learning technology, convolutional neural network (CNN) has been wildly used and achieved the state-of-the-art performances in the area of medical image classification. However, most existing medical image classification methods conduct their experiments on only one public dataset. When applying a well-trained model to a different dataset selected from different sources, the model usually show large performance degradation and need to be fine-tuned before it can be appli...

Abstract Circular RNAs are useful entities for various biotechnology applications, such as templating translation and binding or sequestering miRNA and RNA binding proteins. Circular RNA as highly resistant to degradation in cells and are more long-lived than linear RNAs. Here, we describe a method for intracellular trans ligation of RNA transcripts that can generate hybrid circular RNAs. These hybrid circular RNAs comprise two separate RNA that are covalently linked by ligation to form a circul...
