  1. 1. The Human Spiral Ganglion

    Author : Sven Tylstedt; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; human spiral ganglion; ultrastructural morphology; neural interaction; synaptophysin; connexin; membrane specializations; synapse; gap junction; tight junction; Otorhinolaryngologi; Otorhinolaryngology; Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Abstract : Our knowledge of the fine structure of the Human Spiral Ganglion (HSG) is still inadequate and new treatment techniques for deafness using electric stimulation, call for further information and studies on the neuronal elements of the human cochlea. This thesis presents results of analyses of human cochlear tissue and specimens obtained during neurosurgical transpetrosal removal of life-threatening meningeomas. READ MORE

  2. 2. Strategies in Cochlear Nerve Regeneration, Guidance and Protection : Prospects for Future Cochlear Implants

    Author : Fredrik Edin; Helge Rask-Andersen; Peetra Magnusson; Maoli Duan; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Human vestibular nerve; Scarpa s ganglion; Stem cells; Nanoparticles; Nanocrystalline diamond; Oto-Rhino-Laryngology; Oto-rhino-laryngologi; Medical Science; Medicinsk vetenskap;

    Abstract : Today, it is possible to restore hearing in congenitally deaf children and severely hearing-impaired adults through cochlear implants (CIs). A CI consists of an external sound processor that provides acoustically induced signals to an internal receiver. READ MORE

  3. 3. Modulation of the HPA axis alters the sensitivity of the cochlea to acoustic trauma

    Author : Yeasmin Tahera; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; HPA axis; corticosterone; glucocorticoid receptor; NFêB; spiral ganglion neurons; cochlea; acoustic trauma; paraventricular nucleus;

    Abstract : The hypothalamic pituitary adrenal axis (HPA axis) regulates nearly all neuroendocrine responses of the body. An active HPA axis is crucial to maintaining homeostasis. An altered reactivity of the HPA axis can affect several physiological systems including the auditory system. READ MORE

  4. 4. Investigating a cell replacement therapy in the inner ear

    Author : Zhengqing Hu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Adult neural stem cell; Cell therapy; Differentiation; Dorsal root ganglion; Embryonic stem cell; Gene transfer; Hearing loss; Nerve growth factor; Neurogenin; Organ of Corti; Spiral ganglion; Transplantation;

    Abstract : The mammalian auditory system is sensitive to genetic disorders, aging and injuries caused by overstimulation, ototoxic drugs and viral infections. Since the sensory epithelium (the organ of Corti) and the spiral ganglion neurons (SGNs) in adult mammalian do not regenerate spontaneously when they are damaged, a cell substitution strategy was proposed to compensate the function of the degenerated SGNs.

  5. 5. Tissue engineering of the inner ear

    Author : Shaden Khalifa; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Our knowledge of the regenerative ability of the auditory system is still inadequate. Moreover, new treatment techniques for hearing impairment using cochlear implant and tissue engineering, call for further investigations. READ MORE
