  2. 1. Middle ear mechanics : using temporal bone experiments to improve clinical methods

    Author : Anton Rönnblom; Krister Tano; Magnus Von Unge; Mimmi Werner; Måns Eeg-Olofsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Middle ear; conductive hearing loss; ossiculoplasty; human temporal bone; Laser doppler vibrometry; malleus fracture; middle ear muscles; muscle fiber composition; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Abstract : BackgroundThe middle ear transmits and amplifies sound vibrations from the tympanic membrane via three ossicles to the inner ear. Moreover, it contains two muscles, the stapedius muscle (SM) which protects the inner ear from loud noise, and the tensor tympani (TT) whose function is still debated. READ MORE

  4. 2. The linear and nonlinear biomechanics of the middle ear

    Author : Thomas Wright; Martin Lesser; Viktor Beryuk; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; biomechanics; middle ear models; ossicular chain; Bioteknik; Bioengineering; Bioteknik;

    Abstract : This thesis addresses the biomechanics of the human middle ear, that part of the auditory system which converts sound pressure waves in air to fluid pressure waves in the cochlea. The middle ear's mechanism is analysed in four papers, three main and one supporting; in the main papers the middle ear is treated as a multi-particle, multi-rigid body ensemble possessing a variable number of degrees of freedom depending upon the case being investigated.

  5. 3. Multifunctional roles of plasmin in inflammation : Studies of animal models on rheumatoid arthritis, multiple sclerosis, wound healing and infection

    Author : Jinan Li; Peter Carmeliet; Umeå universitet; []
    Keywords : Plasmin; complement; inflammation; wound healing; infection; autoimmune disease; non-autoimmune disease; rheumatoid arthritis; multiple sclerosis; tympanic membrane; otitis media; medicinsk biokemi; Medical Biochemistry;

    Abstract : Plasmin has been suggested to be involved in degradation of extracellular matrix (ECM) and tissue remodeling during a number of physiological and pathological processes. The aims of this thesis were to study the functional roles of plasmin during pathological inflammation in autoimmune and nonautoimmune disease models of rheumatoid arthritis (RA), multiple sclerosis (MS), wound healing and infection.

  6. 4. Optical Methods for Tympanic Membrane Characterisation : Towards Objective Otoscopy in Otitis Media

    Author : Mikael Sundberg; Tomas Strömberg; Ton van Leeuwen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical Methods; Spectroscopy; Surface Curvature; Monte Carlo; Tympanic Membrane; Otitis Media; Medical engineering; Medicinsk teknik;

    Abstract : Otitis media, which is an upper respiratory tract infection that affect the middle ear, is the second most common disease in childhood, outnumbered in prevalence only by the common cold. Diagnosis of middle ear inflammation is often performed in the primary healthcare where the normal procedure involves anamnesis and physical examination of the tympanic membranes (TM) of the patient, usually be means of otoscopy.

  7. 5. Developing otitis media : experimental studies in particular regarding inflammatory changes in the tympanic membrane

    Author : Per Olof Eriksson; Sten Hellström; Karin Prellner; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; otitis media with effusion; acute otitis media; myringotomy; tympanic membrane; rat; Streptococcus pneumoniae; compound 48 80; mast cell; Otorhinolaryngologi; Otorhinolaryngology; Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Abstract : Otitis media (OM), one of the commonest of childhood diseases, causes much suffering. OM exists in a variety of forms, two of which are acute otitis media (AOM) and otitis media with effusion (OME). READ MORE
