Summary: Mesenchymal stromal cells (MSCs) have shown potential in treating inflammatory and non-inflammatory diseases, but their clinical applications require strict evaluations and monitoring to ensure compliance with safety standards. This study aimed to assess the potential toxicity effects of cryopreserved human bone marrow-derived clonal MSCs in animal models during different time periods.

Summary: This study demonstrates that bone marrow-derived mesenchymal stem cells (MSCs) have vasculogenic properties. Different populations of MSCs vary in angiogenic factor expression and vasculogenic properties. The vasculogenic MSCs (vMSCs), distinct from endothelial progenitor cells (EPCs), may contribute to neovascularization and could be a promising cellular therapy for cardiovascular diseases.

Summary: This research suggests that the cell surface glycoprotein CD24 could serve as a selective biomarker for identifying subpopulations of BMSCs with varying osteogenic potential. CD24(pos) cells have increased expression of genes related to cell adhesion, motility, and extracellular matrix, while also showing reduced proliferation compared to CD24(neg) cells.

Summary: The study identifies a highly proliferative population of mesenchymal cells (hPMC) in midluteal human endometrium, potentially serving as novel decidual precursors; hPMC differ from endometrial stromal cells in the expression of genes for prolactin and other decidual transcription factors, and show signs of differentiation into a decidual subpopulation discovered in early pregnancy; recurrent pregnancy loss is associated with depletion of hPMC.

Summary: The study aimed to improve the accuracy of cochlear measurements postoperatively using fpVCT(SECO) technique. Results showed no significant difference in 2TL measurements, while there was a slight underestimation in CDL postoperatively. These findings can provide guidance for electrode selection and frequency mapping.

Summary: The organ of Corti in the inner ear is responsible for converting auditory signals into neuronal action potentials for processing by the brain. While the role of actin in hearing has been well-studied, this article highlights the importance of microtubules and their regulating mechanisms in the cochlea's function and their implications for hearing research.

Summary: Improved radiological examinations with newly developed 3D models can increase understanding of Meniere's disease (MD). By measuring the angle and length of the vestibular aqueduct (VA) in the temporal bone, and constructing a 3D model to develop the vestibular aqueduct score (VAS), it can be effectively used for diagnostic investigation.

Summary: This study compared two methods of stimulus presentation during auditory brainstem response (ABR) measurements with the Vibrant Soundbridge (VSB) implant. Results showed that using the AcoustiAP for stimulus transmission provided minimal signal distortions and had similar performance to the wireless method. Additionally, the new system allowed for a more stable connection to the implant.

Summary: This study investigated the effect of peg-IGF-1 treatment on the auditory system in the PMN mouse model. The results showed positive effects on OHC synapses and MOC fibers, but no restoration of hearing could be achieved. It suggests that the synaptic pathology of efferent MOC fibers in PMN mice represents a unique form of auditory neuropathy.

Summary: This study demonstrates the feasibility of using evoked electromyographic (EMG) activation of the facial nerve to monitor the electrode insertion during cochlear implantation (CI). The results show that the EMG response evoked by electrical stimulation from the CI increases as the stimulating contact gets closer to the facial nerve during insertion. After full insertion, the contacts on the apical half of the CI array stimulate higher EMG responses compared to those on the basal half.

Summary: The objective of this study was to investigate the benefit of intraoperative auditory brainstem response (ABR) measurements in revision active middle ear implant surgery. Results showed that the application of ABR measurement improved sound field thresholds and enhanced speech understanding. Analysis revealed a significant correlation between intraoperative gain in ABR threshold and postoperative gain in sound field thresholds. Therefore, ABR monitoring can be a useful tool to improve postoperative hearing success, especially in revision surgeries.

Summary: Anatomy-based fitting (ABF) maps are potentially more effective than conventional clinically based fitting (CBF) methods for cochlear implant (CI) users. ABF maps were created using information from exact electrode contact positions determined by high-resolution computer tomography and clinical fitting software. In a study involving 10 bilateral CI users, the ABF map provided better speech understanding in quiet and noisy environments compared to the CBF map. Participants were more likely to accept the ABF map if their electrode array stimulated the apical region of their cochlea. The self-perceived sound quality with the ABF map was similar to the CBF map. ABF mapping may be an effective tool to compensate for frequency-to-place mismatch in experienced bilateral CI users.

Summary: This study investigated the changes in mRNA abundance of genes influencing neural stem cell development and neurogenesis in the rat cochlear nucleus over time. Age- and hearing-specific patterns of changes in mRNA abundance of neurogenically relevant genes were detected. Crucial neurogenic factors with significant and relevant influence on neurogenesis were identified. These findings contribute to a better understanding of the molecular mechanisms underlying the neurogenesis of the auditory pathway.
