Summary: This study proposes a biohybrid tongue based on hypothalamic neuronal network coupled with microelectrode array for real-time glucose perception. Hypothalamic neuronal cultures were cultivated on a two-dimensional brain-on-chip device, enabling the formation of neuronal networks and electrophysiological signal detection. The study investigates the endogenous expression of sweet taste receptors in hypothalamic neuronal cells and explores the spike signal response to sucrose and glucose stimulation. The biohybrid tongue provides insights into glucose sensing mechanisms and hypothalamic neuronal function.

Summary: The efficiency of electroporation treatments depends on the application of a critical electric field over the targeted tissue volume. A deep neural network trained on finite element model simulations was developed to predict tissue properties from a measured voltage ramp, showing minimal test error and great utility in clinical applications. The platform can quickly ascertain patient-specific tissue properties required for treatment planning.

Summary: Real-time digital polymerase chain reaction (qdPCR) integrates absolute quantification with process information, improving precision in molecular diagnostics. We propose a novel approach to determine optimal reaction conditions for qdPCR using real-time fluorescence monitoring in microwells. By leveraging an ultrathin laminated chip (UTL chip), we achieve faster amplification and higher accuracy, showing promise for molecular diagnostics.

Summary: This study developed a novel bioassay for monitoring FK506 using magnetic Janus micromotors and a recombinant chimera receptor. The bioassay utilized a fluorescence competitive method between the drug and the micromotors to achieve a one-step assay without washing steps. The method exhibited a high limit of detection and dynamic range, and was able to operate in raw samples.

Summary: The study aimed to investigate the impact of CTRP4 on inflammation and the interaction between endothelial cells and monocytes under hyperlipidemic conditions. The results showed that CTRP4 reduced the attachment of THP-1 monocytes to HUVECs and decreased inflammation indicators in experimental cells exposed to hyperlipidemic conditions. Additionally, CTRP4 improved the interaction between endothelial cells and monocytes through the SIRT6/Nrf2-dependent pathway.

Summary: In this study, the researchers used signal analysis to study the instantaneous amplitude and phase of sarcomeric oscillations in skeletal muscle. They identified two types of oscillations, sarcomeric oscillations and sarcosynced oscillations, and visualized their behavior during propagating waves. The researchers discovered the presence of sarcomeric defect holes and sarcomeric collision holes, which are important indicators for understanding the oscillation properties of sarcomeres. This finding has important implications for improving our understanding of muscle function and its regulatory mechanisms.
