This thesis concerns vascular endothelial growth factor (VEGF) and its possible role as a neurotrophic factor. I have investigated the effect of VEGF on neurons in culture but also in vivo, following a crush lesion of the sciatic nerve, and following nerve repair. Attempts were also made to unravel the mechanism by which VEGF affects neurons and Schwann cells, using a pharmacological approach in c

The distribution of exogeneous radiolabelled surfactant was investigated in immature newborn lambs who were either ventilated vigorously at birth, and then given surfactant, or who were given surfactant before the first breath. Surfactant distribution was more uniform, and lung mechanics better among the latter.

Gör om, gör rätt, skriver Shai Mulinari. Han vänder sig mot att sjukvården och läkemedelsbolagen fortsätter att sprida bilden av att depres­sion beror på en serotonerg obalans.

I Dramatikanalys. En Introduktion presenteras en uppsättning analysredskap som författaren använt under de år hon undervisat som lektor i Teatervetenskap på Litteraturvetenskapliga institutionen vid Lunds universitet. ”Redskapen” består av ett femtontal ”startpunkter” som växlar mellan dramats helhet och delar. I demonstrationen av analysredskapet förtydligas varje steg med exempel från världsdra

Popular Abstract in Swedish Populärvetenskaplig sammanfattning: När udda blir mainstream - om stress och likriktning i växtsamhället I skogen råder stress på många sätt, och precis som i det mänskliga samhället har stressen i växtsamhället ökat under de senaste decennierna. Dessa händelser har heller inte skett oberoende av varandra. Vårt allt snabbare tempo med krav på ökad tillväxt har inte baSoil acidification has become a source of serious concern in many parts of the world. In southern Sweden, the deposition of acidifying substances, such as nitrogen and sulphur compounds, has decreased the mean pH of forest soils by almost one unit since the 1950s. Apart from H+ ions themselves being harmful to plant roots, the potential toxicity of aluminium (Al) is increased when pH drops below 5

The growing social polarisation in Swedish society has increased the differences between pour and rich districts in the larger cities. The situation is worst in the housing areas built in the 1960s. But although Swedish urban policy has aimed for several decades at controlling segregation through extraordinary efforts in vulnerable housing areas, there is nothing to indicate that the processes of

An Orthogonal Frequency-Division Multiplexing (OFDM) based multi-user massive Multiple-Input Multiple-Output (MIMO) system is considered. The problem of high Peak-to-Average Ratio (PAR) in OFDM based systems is well known and the large number of antennas (RF-chains) at the Base Station (BS) in massive MIMO systems aggravates this further, since large numbers of these Power Amplifiers (PAs) are use
