Hypothermia diminishes the ischemia-induced protein kinase C (PKC) translocation and inhibition, and also reduces transmitter release during ischemia. To study the role of PKC in the mechanism of glutamate release during ischemia, we measured extracellular glutamate levels in the striatum with the microdialysis technique, in the presence and absence in the dialysate of the PKC activator 4β-phorbol
The pigment cells of the compound eye of the shrimps (Crangon crangon andC. allmani) were studied by electron microscopy (SEM and TEM) and microspectrophotometry. The compound eyes of these species contain light-absorbing and -reflecting pigments contained in granules, located in 5 different cells. The light absorbing pigment granules (light screen) are situated in (1) the distal pigment cells, (2
The active membership of Swedish trade unions and union confederations is recorded year for year (women union members in a separate column). The organizational history of the individual trade unions and confederations is also shown.
As the number of autonomous executive agencies increases, some countries have started merging agencies, thereby aiming to reduce fragmentation and cut public spending. These mergers have passed conspicuously unnoticed in research. In Sweden, the current wave of agency mergers started in the 1990ies. This paper aims to (1) give a background to the Swedish trajectory with agency mergers and to (2),
The silicon isotope composition of biogenic silica (δ30SiBSi) in the ocean is a function of the δ30Si of the available dissolved Si (DSi; H2SiO4), the degree of utilisation of the available DSi, and, for some organisms, the concentration of DSi. This makes δ30SiBSi in sediment archives a promising proxy for past DSi concentrations and utilisation. At steady-state, mean δ30SiBSi must equal a weight
This article examines the conceptual framework of the social amplification of risk in relation to the social sciences framework of moral panic and the media violence debate in Britain. The paper will explore the symbolic use of 'risk' in relation to the alleged negative effects of media violence, and analyse the key stages in the social amplification of the physical and moral risks of media violen
This paper investigates the heterogeneity of the sources of external knowledge and their differentiated effects on process and product innovations respectively. The results of the empirical investigations show that the upstream vertical sources of external knowledge from suppliers exert a strong and positive role on the introduction of process innovations, whereas horizontal and downstream vertica
