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

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

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. Binding site

This chapter examines the communicational dynamic between adaptive and flexible CSOs. It focuses on women’s issues and citizen protest movements on the one hand, and political parties on the other, against the background of the extended protests that took place in Romania in the first half of 2012. These protests led to two changes in the government coalition and a significant reshuffling of the R

DDT1 MF-2 cells, which are derived from hamster vas deferens smooth muscle, contain α1-adrenergic receptors (54,800 ± 2700 sites per cell) that are coupled to stimulation of inositol phospholipid metabolism. Incubation of these cells with tumor-promoting phorbol esters, which stimulate calcium- and phospholipid-dependent protein kinase, leads to a marked attenuation of the ability of α1-receptor a

We have synthesized and characterized a high-affinity alpha1-adrenergic receptor probe, 4-amino-6,7-dimethoxy-2[4'-[5''-(3-125I-iodo-4-aminophenyl)pentan oyl]-1'-piperazinyl]quinazoline (125I-A55453). This ligand binds reversibly to rat hepatic plasma membranes with high affinity (K(D) = 77 ± 6 pM), and it labels the same number of 'specific' prazosin-competable sites as the alpha1-adrenergic rece

We have synthesized and characterized a novel high affinity radioiodinated α1-adrenergic receptor photoaffinity probe, 4-amino-6,7-dimethoxy-2-[4-[5-(4-azido-3-[125I]iodophenyl)pentanoyl]-1-p iperazinyl] quinazoline. In the absence of light, this ligand binds with high affinity (K(D) = 130 pM) in a reversible and saturable manner to sites in rat hepatic plasma membranes. The binding is stereoselec

Tumor promoting phorbol esters stimulate Ca++ phospholipid-dependent protein kinase C. It has been suggested that this enzyme regulates the functional properties of different cell membrane receptors. In this study we investigated the effect of phorbol esters on α1-adrenoceptor binding and phosphatidylinositol metabolism in cultured smooth muscle cells derived from rabbit aorta. Treatment of these

BACKGROUND: Amblyopia is the most common monocular visual impairment in Scandinavia. A visual screening programme for preschool children was introduced in Sweden in the 1970s to reduce the prevalence of amblyopia. The purpose of this study was to investigate the impact of this visual screening programme in adult men recruited to the armed forces in Sweden.METHODS: The prevalence of amblyopia was c

Oculomotor behavior reveals, not only the acquisition of visual information at fixation, but also the accumulation of information in memory across subsequent fixations. Two candidate measures were considered as indicators of such dynamic visual memory load: fixation duration and pupil size. While recording these measures, we displayed an arrangement of 3, 4 or 5 targets among distractors. Both occ

Shiga toxin (Stx) is the main virulence factor of enterohemorrhagic Escherichia coli (EHEC), that cause gastrointestinal infection leading to hemolytic uremic syndrome. The aim of this study was to investigate if Stx signals via ATP and if blockade of purinergic receptors could be protective. Stx induced ATP release from HeLa cells and in a mouse model. Toxin induced rapid calcium influx into HeLa

Objective: To study the associations between serum testosterone and risk factors for atherosclerosis in 119 men from general population. Methods: Systolic pressure, body mass index (BMI), testosterone, fasting glucose, glucose tolerance test, apolipoprotein A-1 (ApoA-1), apolipoprotein B (ApoB), and ApoB/ApoA-1 ratio were assessed. Subjects classified into hypogonadal (testosterone ≤ 12 nmol/l), a
