Summary: This study investigated potential vestibular pathway impairment in children with recurrent vertigo using vestibular evoked myogenic potentials (VEMPs) and found significant prolongation of latencies in ACS-cVEMP and GVS-cVEMP, as well as shorter N1 latency in ACS-oVEMP. These findings suggest potential impairment in the inferior vestibular nerve and subsequent nerve conduction pathway in RVC.

Summary: This study aimed to evaluate otolith function in patients with unilateral definite Meniere's disease during the inter-crisis period by comparing the findings of the Subjective Visual Vertical, the cervical Vestibular Evoked Myogenic Potential, and the ocular Vestibular Evoked Myogenic Potential tests. The results showed no significant difference among these tests, indicating concordance.

Summary: By investigating the characteristic parameters and abnormal rates of inner ear tests in BPPV patients, it was found that these patients may have both otolithic and neural dysfunctions, with otolithic organ damage occurring more frequently than retrootolithic neural degeneration.

Summary: Abnormal oVEMP and/or cVEMP results indicate poor auditory outcomes in patients with UISSNHL. Patients with impaired otolith organ function are likely to have a larger and more severe pathological change in their inner ear.

Summary: This study aims to characterize cervical vestibular evoked myogenic potentials (c-VEMPs) in bone conduction (BC) and air conduction (AC) in healthy children, compare the responses to adults, and provide normative values according to age and sex. The results show that the amplitude ratios of AC and BC c-VEMP in children are correlated and higher in men than in women. Children have significantly higher amplitude ratios than adults. This study provides age- and sex-specific normative data for c-VEMPs in children for AC and BC stimulation.

Summary: This study established a standardized rodent model of cervical vestibular evoked myogenic potentials (cVEMPs) and characterized its neural basis, important features, and validation for interpretation and assessment of vestibular function. The results provide a replicable and reliable setup and test protocol for future studies on vestibular dysfunctions and therapeutics.

Summary: The degradation mechanism of human trabecular bone from the central part of the femoral head in a patient with senile osteoporosis was investigated. Severe damages were observed due to osteoclasts and podosome activity, resulting in the disintegration of bone structure. Podosomes create pit marks and holes on the bone surface, leading to the formation of microcracks and a brittle, porous bone structure.

Summary: The study successfully explores the self-purification of nanoparticle mixtures using particle-mediated crystallization, shedding light on the self-assembly mechanisms involved in the process. The depletion-based technique efficiently separates nanoparticles with small differences in size, while the coffee ring technique is more suitable for nanoparticles with significant differences in size and shape.

Summary: The study introduces a method for synthesizing Au@Ag@SiO2 cubes with a uniform silica shell, demonstrating their excellent, highly reproducible, and tunable optical response. By varying the thickness of the silica shell, the excitation energies of the plasmon modes in individual nanoparticles can be adjusted over a broad spectral range. A strong coherent coupling of surface plasmons at the silver-silica interface is revealed, leading to significant field enhancement at the encapsulated NP surface.

Summary: This study examines the assembly of faceted mesocrystals using truncated cubic-shaped iron oxide nanoparticles stabilized by oleic acid molecules, and investigates the effects of synthesis conditions, nanoparticle size, and shape on the mesocrystal structure and morphogenesis. The interactions of the nanoparticles with solvent molecules were analyzed, revealing that the structure of the organic shell is significantly influenced by the nature and polarity of the solvent. The packing symmetry of the mesocrystals showed a clear trend towards different structures based on the shape of the nanoparticles, similar to structural polymorphism observed in classical crystals.

Summary: A novel approach for producing a bioinspired dentine replacement material was introduced, using apatite-gelatin nanocomposites cross-linked with various cross-linkers to resemble mammalian dentine. The combination of effective cross-linker transglutaminase with casein resulted in a cross-linked composite with higher hardness values than human dentine, at 76 HV0.2.

Summary: Mesocrystals are nanostructured materials made up of nanocrystals with a preferred crystallographic orientation. Structural heterogeneity greatly affects their properties, as shown in the detailed structural characterization of a faceted mesocrystal grain made from 60 nm gold nanocubes. Coherent X-ray diffraction imaging revealed intrinsic structural heterogeneity and internal defects, with the average superlattice structure closely matching the real multidomain structure.
