Some years ago it was decided that a European curriculum should be developed for medical physicists professionally engaged in the support of clinical diagnostic imaging departments. With this in mind, EFOMP (European Federation of Organisations for Medical Physics) in association with ESR (European Society of Radiology) nominated an expert working group. This curriculum is now to hand. The curricu

We have examined the binding of [3H]bradykinin to bovine myometrial membranes and assessed its sensitivity to guanine nucleotides. Total binding displayed a typical B2 kinin receptor specificity. However, saturation binding isotherms were resolved into at least two components with K(D) values of 8 pM (45%) and 378 pM (55%). Low affinity binding exhibited relatively rapid rates of association (k(ob

Desensitization of the β-adrenergic receptor, a receptor which is coupled to the stimulation of adenylate cyclase, may be regulated via phosphorylation by a unique protein kinase. This recently discovered enzyme, known as the β-adrenergic receptor kinase, only phosphorylates the agonist-occupied form of the β-adrenergic receptor. To assess whether receptors coupled to the inhibition of adenylate c

Continuous exposure of DDT1 MF-2 smooth muscle cells to 10-100 μM norepinephrine results in a dramatic attenuation of the ability of norepinephrine to stimulate inositol phospholipid hydrolysis via α1-adrenergic receptors (α1-AR). In addition to the functional desensitization, norepinephrine exposure also reduces the number of accessible cell surface α1-AR as assayed by [3H]prazosin binding at 4°

This study explored the effects of adding visual continuous feedback in the form of feedback bars to a teachable-agent based learning game in mathematics. Forty-five (45) children, 8- to 12-years-old, from three Swedish school classes used the game during four math lessons. The focus was on how feedback to the students regarding their teachable agents learning progression - and different detailed

Skriften beskriver hur våldsbejakande högerextremism ser ut i det samtida Sverige. Författaren gör en historisk tillbakablick, belyser internationella kopplingar, symboler och idéer. Inom nationalistiska ideologier har det länge funnits idealbilder om hur män och kvinnor ska vara. Kärnfamiljens betydelse betonas och att uppfostra nationens barn har betraktats som viktigt för att nationen ska överl

Aims: The aim was to investigate associations between the experience of parental separation/divorce in childhood and tobacco smoking in adulthood, adjusting for economic stress in childhood and adulthood and psychological health (General Health Questionnaire GHQ12). Methods: The 2012 public-health survey in Skåne, southern Sweden, is a cross-sectional postal questionnaire population-based study wi

Purpose: The purpose of the study, upon which this paper is based, was to contribute an improved understanding of the vertical extension of buildings, by presenting a development process for its implementation in which the key aspects to consider when planning such extensions are highlighted. Design/methodology/approach: The approach is based on linking the diffusion of innovation together with ca

α1-Adrenergic receptors from the cultured smooth muscle cell line (DDT1 MF-2) have been solubilized with digitonin and purified to apparent homogeneity by sequential chromatography on a biospecific affinity support (Sepharose-A55453 (4-amino-6,7-dimethoxy-2-[4-[5-(4-amino-3-phenyl)pentanoyl]- 1-piperazinyl]-quinazoline), an α1 receptor-selective antagonist), a wheat germ agglutinin-agarose gel, an

Abstract: The adrenergic receptors of rat pineal gland were investigated using radiolabeled ligand binding and photoaffinity labeling techniques. 125I‐2‐[β‐(4‐hydroxyphenyl)ethylaminomethyl]tetralone (125I‐HEAT) and 125I‐cyanopindolol (125I‐CYP) labeled specific sites on rat pineal gland membranes with equilibrium dissociation constants (KD) of 48 (±5) pM and 30 (±5) pM, respectively.
