The soluble and peripheral proteins in the thylakoids of pea were systematically analyzed by using two-dimensional electrophoresis, mass spectrometry, and N-terminal Edman sequencing, followed by database searching. After correcting to eliminate possible isoforms and post-translational modifications, we estimated that there are at least 200 to 230 different(More)
Cyanobacteria are unique prokaryotes since they in addition to outer and plasma membranes contain the photosynthetic membranes (thylakoids). The plasma membranes of Synechocystis 6803, which can be completely purified by density centrifugation and polymer two-phase partitioning, have been found to be more complex than previously anticipated, i.e. they(More)
Rationale: Nicotine replacement therapy (NRT) in varying forms is becoming widely used. Clinicians, therapists and regulatory authorities are interested in the abuse liability and dependence potential of the different forms. Objectives: To compare the abuse liability and dependence potential of nicotine gum, transdermal patch, spray and inhaler. Methods:(More)
The purpose of this article is to analyse the repertoire of possible price models that organisations may deploy for their products and services. This is attained by developing the SBIFT model that suggests that organisations can differentiate by price along five dimensions. Previous research on pricing has been dispersed across different academic(More)
OBJECTIVES To investigate the association between adverse events recorded during critical care and mortality in out-of-hospital cardiac arrest patients treated with therapeutic hypothermia. DESIGN Prospective, observational, registry-based study. SETTING Twenty-two hospitals in Europe and the United States. PATIENTS Between October 2004 and October(More)
Although it has been suggested that mutations of the FLT3, NRAS, KRAS, and PTPN11 genes are particularly frequent in high hyperdiploid (>50 chromosomes) pediatric acute lymphoblastic leukemias (ALLs), this has as yet not been confirmed in a large patient cohort. Furthermore, it is unknown whether mutations of these genes coexist in hyperdiploid cases. We(More)
Photosystem II (PSII) composition was studied in a mutant of the cyanobacteriumSynechosystis 6803 in which synthesis of the reaction center polypeptide D1 has been inactivated. The mutant thylakoids had lost also the other reaction center polypeptide D2 and the chlorophylla-binding protein CP47. Cytochromeb559 and the chlorophylla-binding protein CP43(More)
The PPAR (peroxisome proliferator activated receptor) transcription factors are ligand-activated receptors which regulate genes involved in lipid metabolism and homeostasis. PPARalpha is preferentially expressed in the liver and PPARgamma preferentially in adipose tissue. Activation of PPARalpha leads to peroxisome proliferation in rodents and increased(More)
Rationale: With several different forms of nicotine replacement therapy available for smokers, it is useful to know about factors that may influence choice of form. Objective: To examine factors associated with preference for different nicotine replacement products and effectiveness of these products. The simple comparison of success rates between the(More)
Most of the nuclear encoded mitochondrial precursor proteins contain an N-terminal extension called the presequence that carries targeting information and that is cleaved off after import into mitochondria. The presequences are amphiphilic, positively charged, membrane-interacting peptides with a propensity to form alpha-helices. Here we have investigated(More)
