Advances in deep‐tissue fluorescence imaging through optical clearing: A review

VIEW, EarlyView.
Optical clearing refers to techniques that are used to improve the optical transparency of biological tissues. Optical clearing enables imaging of deeper lying tissues as well as 3D volumetric imaging of whole organs. This review examines reports on the integration of optical clearing with advanced fluorescence imaging techniques, with particular ...

Vestibular dysfunction and postural balance in cochlear implant users: a narrative literature review

Revista CEFAC
Cochlear implants directly stimulate nerve fibers and ganglion cells of the auditory nerve, which transform sound energy into low levels of electrical current, stimulating the remaining fibers of the auditory nerve in patients with severe to profound ...

Betahistine exerts a dose-dependent effect on cochlear stria vascularis blood flow in guinea pigs in vivo. [PDF]

, 2012
Betahistine is a histamine H(1)-receptor agonist and H(3)-receptor antagonist that is administered to treat Menière's disease. Despite widespread use, its pharmacological mode of action has not been entirely elucidated. This study investigated the effect

Four‐dimensional immuno‐mechanobiomaterials: Dynamic material cues that program host response to prevent fibrosis and enable regeneration

VIEW, EarlyView.
Dynamic immuno‐mechanobiomaterials with time‐programmed mechanical adaptation orchestrate host responses through precise mechanotransduction and immune‐stromal regulation. These adaptive biomaterials minimize mechanical mismatch, attenuate the forign dy response and fibrosis, promote angiogenesis and controlled extracellular matrix remodeling, and ...

The impact of the size and angle of the cochlear basal turn on translocation of a pre-curved mid-scala cochlear implant electrode

Scientific Reports
Scalar translocation is a severe form of intra-cochlear trauma during cochlear implant (CI) electrode insertion. This study explored the hypothesis that the dimensions of the cochlear basal turn and orientation of its inferior segment relative to ...

Speech Recognition Deficits in Presbyacusis: Links to Cortical Structural and Functional Alterations

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To characterize speech recognition in presbyacusis and its associated neurophysiological and cortical structural features, and to explore structure‐function‐behavior relationships within the presbyacusis phenotype. Methods Thirty elderly patients with presbyacusis(HI) and thirty‐three healthy young controls(NH) completed a behavioral

Immediate and delayed cochlear neuropathy after noise exposure in pubescent mice.

PLoS ONE, 2015
Moderate acoustic overexposure in adult rodents is known to cause acute loss of synapses on sensory inner hair cells (IHCs) and delayed degeneration of the auditory nerve, despite the completely reversible temporary threshold shift (TTS) and ...

Anatomical Characteristics of the Facial Nerve in Patients With Cochlear Hypoplasia

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To quantitatively characterize the spatial relationships between intratemporal facial nerve segments and key cochlear implantation (CI) landmarks in cochlear hypoplasia (CH), and to compare these features with age‐matched CI recipients with normal inner ear anatomy, thereby informing preoperative planning and facial nerve ...

Selective subperineurial dissection in vestibular schwannoma surgery: how I do it

Acta Neurochirurgica
Background The dissection plane in vestibular schwannoma surgery significantly influences facial and cochlear nerve outcomes. Although histological studies demonstrate that the "tumor capsule" represents vestibular nerve perineurium, epicapsular ...
