  2. 1. Cellular and molecular mechanisms for induction of broad anti-viral B cell responses through vaccination

    Author : Sebastian Ols; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Viral infections contribute to significant morbidity and mortality worldwide. The immense diversity across and within viral families poses a substantial challenge for the development of prophylaxis and therapeutics. Vaccines are one of the most effective medical interventions to prevent infectious diseases. READ MORE

  4. 2. Lignin Model Compounds: Synthesis, Stereochemistry and Acidolysis

    Author : Shiming Li; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; boric acid complexes; Arylglycerol b-aryl ethers; stereochemistry; 3-Diaryl-2-propen-1-ols; 1; Phenylcoumarans; lignin model compounds; acidolysis; ion-exchange chromatography; 3-propanediols; 2-Diaryl-1; 2; X-ray crystallography;

    Abstract : Lignin model compounds representative of structural elements in lignin of the b-1, b-5, b-O-4, cinnamaldehyde and cinnamyl alcohol types were synthesized. erythro-Forms of b-1 models of the 1,2-diaryl-1,3-propanediol type were prepared by BF3-catalyzed rearrangement of chalcone epoxides and subsequent reduction of the rearrangement products with NaBH4.

  5. 3. Effects of healthy aging on balance : a quantitative analysis of clinical tests

    Author : Erika Jonsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Postural control; Balance; Aging; Clinical balance tests; Functional reach; One-leg stance; Tandem stance; Force; Electromyography; Kinematics;

    Abstract : Introduction: Physical therapists employ various tests to assess balance in elderly individuals, but few of these provide adequate information concerning the aspect of balance or postural control that is being measured or the reason for any decline in performance. Furthermore, tools for assessment of balance should serve as a basis for adequate intervention. READ MORE

  6. 4. Oligodendrocyte pathology following Traumatic Brain Injury : Experimental and clinical studies

    Author : Johanna Flygt; Niklas Marklund; Fredrik Piehl; Uppsala universitet; []
    Keywords : Traumatic brain injury; oligodendrocytes; oligodendrocyte progenitor cells; interleukin 1-β; central fluid percussion injury; Neurokirurgi; Neurosurgery; Neurokirurgi; Neurosurgery;

    Abstract : Traumatic brain injury (TBI) caused by traffic and fall accidents, sports-related injuries and violence commonly results in life-changing disabilities. Cognitive impairments following TBI may be due to disruption of axons, stretched by the acceleration/deceleration forces of the initial impact, and their surrounding myelin in neuronal networks.

  7. 5. Demyelinating conditions regulated by ROS pathways outside and inside the brain

    Author : Karl Carlström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Multiple sclerosis (MS) is a chronic inflammatory condition of the central nervous system with immune-mediated damage on myelinated nerve tracts. Accumulating evidence support a role for autoreactive T-lymphocytes orchestrating immuneattacks on myelinating oligodendrocytes (OLs). READ MORE
