    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; teaching; primary and secondary school; plants; photosynthesis and respiration; Undervisning; mellan- och högstadiet; växter; fotosyntes och cellandning; Subject didactics; Ämnesdidaktik; didactics of natural science; naturvetenskapens didaktik;

    Sammanfattning : According to previous research, students show difficulties in understanding photosynthesis and respiration, and basic ecological concepts like energy flow in ecosystems. There are successful teaching units accomplished in this area and many of them can be described as inquiry-based teaching. LÄS MER

  3. 2. Medical Treatment and Grading of Bell's Palsy

    Författare :Thomas Berg; Mats Holmström; Lars Jonsson; Mats Engström; Dan Bagger-Sjöbäck; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bell s palsy; facial grading; prednisolone; valaciclovir; Sunnybrook; House-Brackmann; Yanagihara; last observation carried forward; complete-case analysis; Otorhinolaryngology; Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Sammanfattning : The main aim of this thesis was to evaluate the effect of prednisolone and valaciclovir in a large number of Bell's palsy patients. The incidence and intensity of pain around the ear, in the face or in the neck during the first two months of palsy, and its prognostic value, was also assessed. LÄS MER

  4. 3. Applications of organ culture of the mouse inner ear

    Författare :Diana Berggren; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; organ culture; embryonic inner ear; intercellular junctions; aminoglycosides; statoacoustic ganglion; intermediate filaments; collagen; endolymph;

    Sammanfattning : The embryonic mouse inner ear was used as a model with which to study ototoxicity and tissue interactions. The inner ear anlage can be explanted and cultured in vitro from about the 12th gestational day (gd), and will differentiate parallel with the inner ear developing in vivo until a time corresponding to birth (21st gd).

  5. 4. Impaired reparative processes in particular related to hyaluronan in various cutaneous disorders : a structural analysis

    Författare :Ulf Bertheim; Bengt Gerdin; Umeå universitet; []
    Nyckelord :hyaluronan; scar tissue; diabetes mellitus; basal cell carcinoma; skin; wound healing; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Sammanfattning : Cutaneous reparative processes, including wound healing, are highly developed procedures in which a chain of actions occurs to reconstitute the function of the wounded tissue. To prevent a delayed or excessive reparative process it is important to understand how this procedure develops and is maintained. LÄS MER

  7. 5. Middle Ear Cholesteatoma : Surgical Treatment, Follow-up and Hearing Restoration

    Nyckelord :Oto-Rhino-Laryngology; Oto-rhino-laryngologi;

    Sammanfattning : Although middle-ear cholesteatoma is a major topic in otological research, its etiology and pathogenesis remain unclear. Pediatric cholesteatoma is considered more aggressive than adult cholesteatoma, as it has a higher rate of growth, is more often infected and exhibits wider extension. LÄS MER
