BACKGROUND: Migraine is diagnosed using the extensively field-tested International Classification of Headache Disorders (ICHD-3) consensus criteria derived by the International Headache Society. To evaluate the criteria in respect to a measurable biomarker, we studied the relationship between the main...

Ice-Templated Cellulose Nanofiber Filaments as a Reinforcement Material in Epoxy Composites.

Nanomaterials (Basel, Switzerland)

Nissilä T, Wei J, Geng S, Teleman A, Oksman K.
PMID: 33672079
Nanomaterials (Basel). 2021 Feb 15;11(2). doi: 10.3390/nano11020490.

Finding renewable alternatives to the commonly used reinforcement materials in composites is attracting a significant amount of research interest. Nanocellulose is a promising candidate owing to its wide availability and favorable properties such as high Young's modulus. This study...

HLA-DQ and HLA-DRB1 alleles associated with Henoch-Schönlein purpura nephritis in Finnish pediatric population: a genome-wide association study.

Pediatric nephrology (Berlin, Germany)

Formation of vacancy-impurity complexes by kinetic processes in highly As-doped Si.

Phys Rev Lett. 2002 Mar 11;88(10):105506. doi: 10.1103/PhysRevLett.88.105506. Epub 2002 Feb 25.

Positron annihilation experiments have been applied to verify the formation mechanism of electrically inactive vacancy-impurity clusters in highly n-type Si. We show that the migration of V-As pairs at 450 K leads to the formation of V-As2 complexes, which...
