  2. 1. Spatial Vision in Birds: Anatomical investigation of spatial resolving power

    Author : Mindaugas Mitkus; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Raptors; Seabirds; Parrots; Birds; Double cones; Development; Retinal ganglion cells; Visual spatial resolution; Visual ecology; Vision;

    Abstract : Avian eyes are big both in relative and absolute terms, thus the importance of vision to birds is obvious. Even though the general eye plan is rather conservative throughout the group, there is a great variation in visual capabilities. READ MORE

  4. 2. Identification and Characterization of the Moraxella catarrhalis IgD-binding Protein MID

    Author : Andrea Möllenkvist; Malmö Klinisk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; receptor; structure; phase variation; MID; IgD; Moraxella catarrhalis; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Moraxella catarrhalis is now an established human pathogen that frequently colonizes the upper respiratory tract causing most importantly otitis media in children. It has also been associated with sinusitis, laryngitis and lower respiratory tract infections in adults with predisposing conditions such as chronic obstructive pulmonary disease (COPD). READ MORE

  5. 3. Towards Intelligent Deformable Models for Medical Image Analysis

    Author : Ghassan Hamarneh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shape modeling; deformable models; principal component analysis; echocardiography; snakes; active shape models; deformable spatio-temporal shape models; medial-based shape profiles; statistical shape variation; spatio-temporal shape analysis; magnetic resonance imaging; hierarchical regional principal component analysis; oral lesions; dynamic programming; segmentation; spring-mass model; shape deformation; optical flow; medical image analysis; artificial life; physics-based modeling; deformable organisms; digital color images; medial axis; active contour models;

    Abstract : Medical imaging continues to permeate the practice of medicine, but automated yet accurate segmentation and labeling of anatomical structures continues to be a major obstacle to computerized medical image analysis (MIA). Deformable models, with its profound roots in estimation theory, optimization, and physics-based dynamical systems, represent a powerful approach to the general problem of medical image segmentation.

  6. 4. Quantitative cataract measurement with the Scheimpflug technique

    Author : Wen Qian; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Scheimpflug photography; back scattered light; cataracts; human lens nuclear opacities; aqueous suspension of polystyrene spheres; standard of opacity;

    Abstract : Cataract is the most prevalent blinding eye disease. Scheimpflug photography is an objective method for documentation of lens nuclear opacity. Using the Scheimpflug slit-lamp technique, a photograph, in focus from the anterior surface of the cornea to the posterior surface of the lens, can be obtained. READ MORE

  7. 5. Aspects of chemotherapy and photon and proton radiotherapy in patients with gastric cancer

    Author : Michael Gubanski; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Gastric cancer remains a major health problem worldwide. The addition of chemotherapy alone or in combination with radiotherapy to surgery in local gastric cancer improves outcome. In more advanced stages, the optimal palliative chemotherapy remains unknown, as well as the effect of different regimens on the patients’ quality of life. READ MORE
