Summary: The study demonstrates that ultra-high-field diffusion tensor imaging (UHF-DTI) combined with neurite orientation dispersion imaging (NODDI) can detect concussions of variable intensities. Microstructural changes following a concussion mainly affect the white matter in the mouse brain, with associated white matter degeneration and neuroinflammation.

Summary: Comparing the neuroanatomical features of the brain in humans, our evolutionary relatives, and nonhuman primates is crucial for understanding the human brain system and the neural basis of mental and neurological disorders. Research on various species of nonhuman primates is necessary to elucidate the diversity of neuroanatomy features among humans and nonhuman primates. A data-repository of anatomical images obtained using MRI of postmortem brain samples has been developed, and T2-weighted and diffusion tensor images of nine species have been released, contributing to scientific discoveries and promoting animal ethics, animal welfare, and conservation efforts.

Summary: By using gravity and magnetic data derived from satellites, it has been found that there may be an impact structure in the Badain Jaran Desert. The gravity indicators show typical annular gravity highs surrounding a gravity low. The magnetic indicators reveal a large magnetic anomaly in the southern part of the proposed crater, which is further restricted by the rim.

Summary: Understanding the relationship between the built environment and taxi ridership in different spatial-temporal patterns is important for transport planning. This paper proposes an analytical framework combining NCP decomposition and LightGBM modeling to extract patterns and examine their associations. The case study in Shenzhen identifies four patterns and reveals nonlinear relationships between taxi ridership and factors such as demographic characteristics, housing-price, and types of POIs. These findings have implications for local transport planning.

Summary: The performance of terahertz devices can be significantly improved by using optical regulation strategy with the aid of hybrid materials, such as gold nanobipyramids (AuNBPs). The introduction of AuNBPs can effectively enhance the modulation depth of terahertz modulators, and an ultrahigh modulation enhancement can be achieved in the AuNBPs hybrid metamaterials. The optical regulation with AuNBPs is attributed to increased damping rate and higher coupling coefficient.

Summary: In this study, the researchers evaluated the osteogenic differentiation of ectomesenchymal stem cells (EMSCs) using an alendronate-loaded chitosan/polycaprolactone scaffold (CS/PCL@AL) in vitro. The results showed that the CS/PCL@AL scaffold enhanced osteogenic differentiation by upregulating bone morphogenetic protein 2, interleukin 10, and laminin expression, as well as activating the yes-associated protein (YAP) signaling pathway. In vivo experiments in rats with calvarial defects also demonstrated that the CS/PCL@AL scaffold promoted new and mature bone formation. This study highlights the potential of CS/PCL@AL scaffolds as an efficient delivery system for bone defect repair.

Summary: In this study, a magnetic shear strain device was developed to analyze the response of human breast gland cells to shear strain. The results showed that breast spheroids have resistance to shear strain, which increases with the maturation of the basement membrane and basoapical polarization. Interestingly, poorly developed spheroids were more prone to the extrusion of apoptotic cells under cyclic strain. This new device provides a versatile tool to study the response of 3D cell culture models to cyclic shear stress.

Summary: The discovery of carbon-based quantum dots (CQDs) has opened up opportunities for various applications such as fluorescence bioimaging and tumor diagnosis. However, existing reviews have focused primarily on the applications rather than the formation mechanism of CQDs. This review provides a summary of the relationships between the intrinsic properties of building blocks and the photoluminescence properties of CQDs, with a focus on the bottom-up approach and the influence of different descriptors such as topology, chirality, and free radical process.

Summary: A novel sandwich-type electrochemical immunosensor was developed for the quantitative detection of carcinoembryonic antigen, a significant tumor marker. The immobilization of antibodies was achieved through Au-S bonds using a novel photochemical technique, allowing control over antibody orientation. The SWCNH/Thi/AuNPs nanocomposite acted as a signal tag for detection and signal amplification. The immunoassay demonstrated a linear detection range from 0.001-200 ng/mL with a low detection limit of 0.1385 pg/mL. Carbon nanohorns hold promise as a conductive and binding matrix for signal amplification in clinical diagnostics.

Summary: This paper proposes an efficient calibration method for planar SQUID gradiometers based on MGT components. The factors affecting the calibration accuracy and the optimal inclination angle for calibration were investigated. Numerical models were built to simulate the response of planar gradiometers and various error factors were taken into account. A calibration setup was built to achieve high-precision simultaneous calibration of multi-channel planar SQUID gradiometers and the effect of eddy current on the calibration accuracy was investigated. The results show that a calibration error of about 0.4% is achieved.

Summary: Magnetic relaxation switches (MRS) based on the state changes of magnetic nanoparticles are important for biomolecule detection in in vitro diagnosis. Magnetic graphene quantum dots have been used as magnetic probes and shown high sensitivity. This study developed a magnetic separation-assisted MRS to detect endoglin, using iron oxide as the magnetic carrier and magnetic graphene quantum dots as the magnetic probe. The assay demonstrated a broad linear range and a sensitive limit of detection, which is two orders of magnitude lower than that of MRS without magnetic separation.

Summary: This research examines the impact of Buddhism on mergers & acquisitions (M&As) performance using data from 4622 M&A transactions of Chinese public firms between 2004 and 2018. The findings provide ample evidence that acquirers located in regions with a higher intensity of Buddhism achieve better short-term and long-term performance after the merger. Furthermore, the study reveals that state ownership plays a crucial role in mitigating this effect, and the value creation is driven by higher deal completion rates and fewer violation cases for acquiring firms. Finally, the study addresses the issue of endogeneity, and the results remain unchanged.

Summary: This study presents an electrochemical aptasensor for highly sensitive and selective serotonin (ST) detection, based on truncated DNA aptamers and a polyethylene glycol (PEG) molecule-functionalized sensing interface. The aptasensor shows improved sensitivity and enhanced antifouling ability due to the small size and stable structure of the truncated aptamers, as well as the blocking effect of PEG molecules. The sensor exhibits a wide detection range and low limit of detection, and also demonstrates high selectivity and stability in detecting ST in human serum and artificial cerebrospinal fluid (aCSF).
