Summary: Housing and infrastructure works are crucial for development in all countries due to the expansion of cities and industries. While the search for alternative materials is important, there is also a growing need to find techniques for characterizing construction materials that are more environmentally friendly and meet technical requirements. This study investigated the influence of specimen dimensions and electrical contacts on electrical impedance measurements of cementitious composites. The experimental results showed a dependence on impedance behavior based on specimen dimensions and the number of electrical contacts. These findings are valuable for characterizing and interpreting electrical impedance measurements of cementitious composites.

Summary: Obesity is a serious health concern that can lead to various diseases. The widely used measure of obesity, BMI, does not accurately classify obesity and overlooks individual body type. To address this limitation, we conducted a study using 3D measurements of the human body, focusing on Korean subjects. By collecting 3D body scans, Dual-energy X-ray absorptiometry, and Bioelectrical Impedance Analysis data from 160 Korean subjects, we developed a machine learning-based obesity classification framework and compared its performance with BMI and BIA. Our proposed model demonstrated higher accuracy in obesity classification than BMI and BIA, and can be utilized for obesity management through 3D body scans.

Summary: This study investigates the relationship between cochlear implant electrode positioning and electrical impedance measurements. The results show that three-point and four-point impedances are strongly correlated with electrode-modiolar distance, while monopolar impedances are minimally affected by changes in electrode positioning. The findings have significant implications for predicting electrode positioning during cochlear implant insertion in real-time using electrical impedance measurements.

Summary: This article introduces the research results of using nucleases to improve the sensitivity, specificity, and cost-effectiveness of aptamer sensors. The author serendipitously discovered that the digestion of DNA aptamers by exonucleases is inhibited when an aptamer is bound to a ligand, which laid the foundation for the development of three novel aptamer-related methodologies. The enzymatic technologies described in this article can greatly streamline the aptamer characterization and sensor development process.

Summary: Moisture content significantly affects the durability and service life of concrete structures. Non-invasive electrical techniques are commonly used to measure moisture content and correlate electrical response to the Degree of Saturation (DoS) of the material. A study successfully reconstructed the impedance distribution along the length of samples and proposed an empirical relationship between DoS and impedance for estimating moisture profiles in samples with different moisture distributions.

Summary: There is a need for improved methods to quantify bone healing during fracture care. Researchers have developed a smart bone plate that utilizes electrical impedance spectroscopy to monitor tissue composition within the fracture callus in real-time. The results showed that the smart bone plate successfully incorporated into the fracture callus and provided continuous and sensitive measurements of tissue throughout the course of fracture healing. These measurements significantly correlated with traditional measurements of bone healing and could distinguish between union and not-healed fractures.

Summary: Classical microbiology played a crucial role in the development of modern biotechnology and microbial biosensing platforms. The invention of the Petri plate revolutionized the field of microbiology and continues to have a profound impact on isolating, identifying, and studying microorganisms. The use of sensing devices to detect and identify bacteria directly on the plate has the potential to further revolutionize microbiology, particularly in gene sequencing, pathogenicity study, and characterizing industrially beneficial traits.

Summary: In this study, it is discovered that internalin B (InlB) is the main ligand of listeria adhesion protein (LAP) and their interaction is critical for listeria monocytogenes (Lm) to cross the intestinal epithelium. Deletion or deficiency of InlB reduces LAP-InlB interaction and LAP-mediated pathology in mice. InlB overexpression in non-pathogenic listeria innocua also leads to LAP-InlB interaction. In silico analysis reveals that a pocket region in the C-terminal domain of tetrameric LAP is the binding site for InlB. Mutations in negatively charged amino acids in the C terminus of LAP confirm altered binding conformation and weaker affinity for InlB. InlB transforms the housekeeping enzyme, AdhE (LAP), into a moonlighting pathogenic factor by binding to the cell surface.

Summary: Salmonella is a common zoonotic foodborne pathogen that poses a global public health threat. Transmission of Salmonella to humans occurs through contaminated animal- and plant-derived foods along the farm-to-fork continuum. The virulence factors of Salmonella, including capsule, adhesion proteins, flagella, plasmids, and type III secretion systems, play crucial roles in attaching, invading, and evading the host defense system. The increasing global prevalence of non-typhoidal Salmonella (NTS) serovars and the emergence of antibiotic-resistant variants highlight the need for effective control measures to ensure food safety.
