Bjursten, Henrik, Per Ederoth, Engilbert Sigurdsson, Magnus Gottfredsson, Ingvar Syk, Orri Einarsson, and Tomas Gudbjartsson. S100B profiles and cognitive function at high altitude. High Alt. Med. Biol. 11:31-38, 2010.-Exposure to high altitude can lead to acute mountain sickness (AMS) and high altitude cerebral edema (HACE). In this study we investigated the effect of high altitude on neurocognit

In this introductory retrospective, evolution as viewed through gene trees is inspected through a lens compounded from its founding operational assumptions. The four assumptions of the gene tree culture that are singularly important to evolutionary interpretations are: a. that protein-coding sequences are molecular fossils; b. that gene trees are equivalent to species trees; c. that the tree of li

Traditional approaches for understanding environmental governance - such as environmental policy analysis or natural resources management - do not adequately address the gamut of human-natural system interactions within the context of the complex biogeophysical cycles and processes of the planet. This is perhaps more so in the African regional context where the complex relationships between modern

Post-translational modification of different proteins via direct ubiquitin attachment is vital for mediating various cellular processes. CYLD, a deubiquitination enzyme, is able to cleave the polyubiquitin chains from the substrate, and to regulate different signaling pathways. Loss, or reduced expression, of CYLD is observed in different types of human cancer, such as hepatocellular carcinoma (HC

Tendons are important load-bearing structures, which are frequently injured in both sports and work. Type I collagen fibrils are the primary components of tendons and carry most of the mechanical loads experienced by the tissue, however, knowledge of how load is transmitted between and within fibrils is limited. The presence of covalent enzymatic cross-links between collagen molecules is an import

Species of Eunicida (polychaetous annelids) have complex jaw apparatuses with ventral mandibles growing throughout life, but dorsal maxillae undergoing successive moulting episodes. Jaw ontogeny was studied in the eunicid Marphysa fauchaldi, from the appearance of the mandibles and larval maxillae through two moults during the transformation to juvenile and sub-adult maxillae. Although larval maxi

Irish peat soils are extensive, covering approximately 14-20% of the national land area. They contain between 53% and 62% of the national soil organic carbon stock. Montane blanket bog covers approximately 25% or 242650ha of the total peatland area in Ireland and is the dominant peatland type covering the upland area of Wicklow. Blanket bogs are very sensitive systems and have experienced much dis
