Sammanfattning : Glioblastoma multiforme (GBM) is the most common and lethal form of primary brain tumor that mainly affects adults. GBM displays remarkable intra- and inter-tumoral heterogeneity and contains a subpopulation of cells named glioma stem cells that is believed to be responsible for tumor maintenance, progression and recurrence.

2. Influence of postoperative treatment, surface treatment and stem design on the outcome of primary total hip arthroplasty
Sammanfattning : Aims: The aim of this study was to investigate the influence of postoperative treatment, surface treatment and stem design on the outcome of primary Total Hip Arthroplasty. The main intention was to study anteverted femoral stems. LÄS MER
Sammanfattning : Peripheral nerve injury (PNI) is common and despite modern microsurgical techniques of repair, functional restoration is always incomplete. This results in impaired sensation and reduced motor function alongside pain and cold intolerance. LÄS MER
4. Exceptionally Preserved Cambrian Lophotrochozoa : Taxonomy, Systematics and Taphonomy of Chengjiang and Indian Springs Lophophorates
Sammanfattning : The origin and evolution of Lophotrochozoa can be traced to the plethora of lower Cambrian scleritome taxa. We aim to determine the character suites linking these stem-Lophotrochozoa to their extant crown relatives, in particular the small shelly tommotiids and the stem-group brachiopods. LÄS MER
5. Decoding the fossil record of early lophophorates : Systematics and phylogeny of problematic Cambrian Lophotrochozoa
Sammanfattning : The evolutionary origins of animal phyla are intimately linked with the Cambrian explosion, a period of radical ecological and evolutionary innovation that begins approximately 540 Mya and continues for some 20 million years, during which most major animal groups appear. Lophotrochozoa, a major group of protostome animals that includes molluscs, annelids and brachiopods, represent a significant component of the oldest known fossil records of biomineralised animals, as disclosed by the enigmatic ‘small shelly fossil’ faunas of the early Cambrian.
