Summary: The detection and quantification of biomarkers in blood is crucial for the early identification, diagnosis, and treatment of various diseases. Affinity-based electrochemical sensors, which offer high sensitivity, specificity, fast detection times, ease of use, and portability, are a promising approach for detecting molecular biomarkers. However, the complexity of whole blood poses challenges, requiring sample purification and sophisticated equipment. This article provides an overview of strategies employed to improve the performance of affinity-based electrochemical sensors for biomolecular detection in whole blood.

Summary: The trans-cleavage activity of Cas12a is affected by the length of the fluorescent probe and the reaction buffer. The optimal conditions for Cas12a are a probe length of 15 nucleotides and NEBuffer 4 as the buffer, resulting in a 50-fold improvement in activity and a significant decrease in the detection limit for DNA targets. This method provides a powerful tool for Cas12a trans-cleavage activity applications.

Summary: Mucormycosis, a life-threatening condition, is a post-COVID-19 side effect that requires early identification and timely treatment. Conventional diagnostic techniques have limitations in early detection, necessitating the use of advanced tools such as nucleic acid diagnostics and PCR. These tools aid in the prevention of adverse outcomes by identifying invasive fungal infections at an early stage.

Summary: The development of a new cascaded droplet microfluidic platform has addressed the scalability constraint in rapid single-cell AST technologies, demonstrating the potential for generating multiple groups of droplets with custom antibiotic conditions within a single device. This platform has shown promising results in producing clinically useful antibiograms with minimum inhibitory concentrations in approximately 90 minutes for the first antibiotic and 2 minutes for each subsequent antibiotic condition. The platform also demonstrated potential clinical utility in testing clinical isolates and urine specimens against commonly used antibiotics, achieving high categorical agreements with laboratory-based results in a significantly shorter timeframe.

Summary: This study proposes a new scalable model family called PlexusNet, which regulates its architecture by network's depth, width, and branch. It also includes a new learnable data normalization algorithm. The designed PlexusNet achieves comparable performance to SOTA models ResNet-18 and EfficientNet B0/1 in five clinical classification problems, but with lower parameter capacity and representative feature maps.

Summary: The study aimed to evaluate the necessity of restaging transurethral resection of bladder tumor (TURBT) in high-risk nonmuscle invasive bladder cancer (NMIBC) if the initial TURBT was performed using blue light (BL) technology. Through analysis of patient data from the Cysview registry, it was found that restaging TURBT is still necessary even if initial TURBT was performed using BL, as BL did not reduce rates of residual disease or risk of upstaging in Ta or T1 disease.

Summary: Cancer cells collectively invade using a leader-follower organization, and the regulation of leader cells is poorly understood. In this study, a dual double-stranded LNA nanobiosensor was used to track the dynamics of lncRNA in live single cells during collective cancer invasion. The results show that the lncRNA MALAT1 is dynamically regulated in the invading fronts of cancer cells. Transient knockdown of MALAT1 prevents the formation of leader cells and abolishes cancer cell invasion.

Summary: In this study, four advanced sequential models (SlowFast, Multiscale Vision Transformers, X3D, and CNN-LSTM) were used to train and classify bladder tumors. The best performing model was X3D with a sequence length of 8, achieving 100% sensitivity, 94.7% sensitivity, and 80.0% specificity. Sequential modeling has the potential to accurately classify a wide variety of bladder tumors in a real-time setting.

Summary: We developed a novel transparent ultrasound transducer (TUT) platform for low intensity pulsed ultrasound (LIPUS) stimulation of cells and simultaneous imaging of live cell fluorescent calcium dynamics. The TUT platform eliminates the need for additional acoustic coupling and reduces contamination risk. The high light transmission and compact size of TUTs allow easy integration with state-of-the-art microscopy for high-resolution imaging of cells.
