Popular Abstract in Swedish Cellulära mekanismer vid ischemisk tolerans Stroke, hjärntrauma, hjärnblödning och övergående hjärtstillestånd, leder till minskat blodflöde till hjärnan (ischemi) och orsakar hjärnskador. Mot denna skadeutveckling finns ännu inte något medel för kliniskt bruk. I djurexperimentella ischemimodeller har man kunnat skydda hjärnan mot ischemiska skador genom att utsätta hjäA brief period of sublethal ischemia in the brain induces resistance to a subsequent, otherwise lethal ischemic insult. This phenomenon is known as ischemic tolerance or preconditioning. A model of ischemic preconditioning in the rat brain using the two-vessel occlusion model of global cerebral ischemia was established. Using this model we have demonstrated that ischemic preconditioning protects t

The purpose of this paper is to discuss the conceptualisation of bibliometric analyses in terms of the levels on which they are performed, adding contextual factors to the dimension where the size of the unit being analysed is considered. Based on empirical investigations of resource allocation systems and research evaluation practices, as well as the previous literature conceptualising bibliometr

Nanowires and nanotubes are very promising tools for biological applications. Their small dimensions, which are on the same length scale as many cell components, make them an ideal tool to probe and stimulate cells with minimal perturbation. Here, we present a review of our work towards using nanowires and nanotubes for biomedical applications, such as neural implant, mechanosensing, and cell tran

We make Deterministic Lateral Displacement (DLD) flexible by combining it with AC electrokinetics.

We have fabricated a silicon-glass two-phase droplet-based microfluidic system and implemented two-dimensional acoustic focusing prior to droplet generation as well as continuously throughout the whole system to increase particle detectability. Using acoustic focusing we have effectively minimized sedimentation of the encapsulated particles and thereby increased particle detectability by as much a

Direct and precise manipulation of sub-micron particles such as bacteria, platelets, organelles, microvesicles, exosomes or virus particles is challenging. We describe for the first time how acoustic streaming in the bulk can be efficiently reduced by introducing a density or compressibility gradient and that this enables focusing of 500-nm-diameter particles in a standard acoustophoresis channel.

G.Fast is a new standard for fixed broadband access that aims at achieving bit rates of 1 Gb/s over short copper loops. In order to give support to simulation, design and performance evaluation tests, the G.Fast recommendation presents examples of some wiring topologies and reference loops describing configurations expected to be found in real G.Fast deployments. Our work describes results of mode

The Swedish army marched 1658 over the ice on the Danish sounds from Jutland to Zealand. An event that led to the foundation of Lund University in 1666. From the loads involved the ice thickness can be determined to have been at least 20 cm. Using data from mid-17 hundreds and forward the ice thickness of every year is computed. Large ice thickness seems to have been more common in the period mid

Background: The receptors for advanced glycation end products (RAGE) are increased in atherosclerotic plaques. Soluble (s)RAGE decreases, whereas the extracellular newly identified receptor for advanced glycation end products (EN-RAGE) increases inflammatory responses mediated by RAGE. The aims were to explore whether sRAGE, EN-RAGE and the EN-RAGE/sRAGE ratio, were associated with the use of lipi
