Serotonergic receptors were classified in the isolated human uterine artery with intact endothelium, using agonists and antagonists for 5-hydroxytryptamine (5-HT) receptors. The efficacy for different agonists rated: alpha-methyl-5-HT (5-HT2) = 5-HT (non-selective) = 2-methyl-5-HT (5-HT3) >> sumatriptan (5-HT1), and the potency as: sumatriptan = 5-HT > 5-HT > alpha-methyl-5-HT > 2-methyl-5-HT. The
How animals adjust their foraging or mate finding behaviour according to the risk of predation has received much attention recently. However, few studies have focused on the behaviour of prey when stimuli representing different adaptive behaviours originate from different sensory modalities. Here we present data on how male moths trade off odour-mediated mate attraction and auditory-mediated preda
An electron storage ring acts as an approximate point source in the far-infrared spectral region with a much greater intensity than provided by conventional black body radiators. Far-infrared synchrotron radiation is therefore suitable for high-resolution spectroscopic measurements of low-frequency vibrations for metastable molecules such as the intermolecular vibrational modes of hydrogen-bonded
1 The main objective of this study was to predict the responses of vascular plant species to atmospheric nitrogen deposition and enhanced soil nitrogen levels. The study was carried out in deciduous forests located in three regions of southern Sweden. The abundance of vascular plants, as well as soil pH and nitrogen mineralization rates, were studied in a total of 661 sample plots. 2 We calculated
We study here deterministic broadcasting in geometric radio networks (GRN) whose nodes have complete knowledge of the network. Nodes of a GRN are deployed in the Euclidean plane (R 2) and each of them can transmit within some range r assigned to it. We adopt model in which ranges of nodes are non-uniform and they are drawn from the predefined interval 0 ≤ r min ≤ r max . All our results are in the
The present study is included in a project with the aim to develop attractants from food odors for trapping female moths. Males and mated, but not unmated, females of Ephestia cautella and Plodia interpunctella were attracted by odors of three different chocolate products in flight tunnel experiments. Chocolate containing nut or rum elicited upwind flight and landing responses. Extracts of the cho
Impaired survival of skin grafts has been noted in human immunodeficiency virus (HIV) infected patients, but the reason is not known. Alterations in inflammatory response, which might be recorded as an imbalance in cytokine production, have been implicated. The aim of this study was to determine the impact of HIV infection in patients with burn injuries by comparison of split skin graft survival,
OBJECTIVE: Desmin intermediate filaments are key structures in the cytoskeleton of cardiac muscle. Since they are associated with Z-discs and intercalated discs, they may have a role in sarcomere alignment or force transmission. We have explored the mechanical function of the desmin filaments in the cardiac wall by comparing desmin-deficient (Des-/-) and wild-type (Des+/+) mice. METHODS: The Lange
Smoking has recently been recognised as causally associated with the development of gastric cancer (GC). However, evidence on the effect by sex, duration and intensity of smoking, anatomic subsite and cessation of smoking is limited. Our objective was to assess the relation between tobacco use and GC incidence in the European Prospective Investigation into Cancer and Nutrition (EPIC). We studied d
The neural cell adhesion molecule (NCAM) is required for cell type segregation during pancreatic islet organogenesis. We have investigated the functional consequences of ablating NCAM on pancreatic beta-cell function. In vivo, NCAM(-/-) mice exhibit impaired glucose tolerance and basal hyperinsulinemia. Insulin secretion from isolated NCAM(-/-) islets is enhanced at glucose concentrations below 15
For measuring the physical exposure/workload in studies of work-related musculoskeletal disorders, direct measurements are valuable. However, the between-days and between-subjects variability, as well as the precision of the method per se, are not well known. In a laboratory, six women performed three standardised assembly tasks, all of them repeated on three different days. Triaxial inclinometers
Background There have been no reports on the long-term outcome of radial neck Mason type IIIb fractures in adults. Methods 3 women and 2 men, aged 46 (22-69) years when they sustained a radial neck Mason type IIIb fracture, were evaluated after an average of 18 (16-21) years. All had been treated with radial head excision. Results 3 individuals had no subjective elbow complaints while 2 reported o
Roentgen stereophotogrammetric analysis (RSA) was used to evaluate the migration in 17 cemented acetabular components after revision operations for mechanical loosening. All of the hips were examined four months and one year after surgery; ten of the hips were also examined after two years. In 15 of the 17 components, definite migration (0.5-2.7 mm) was identified, whereas two acetabular component
The room-temperature Raman and infrared spectra of zirconium vanadate (ZrV2O7) were observed up to pressures of 12 GPa and 5.7 GPa, respectively. The frequencies of the optically active modes at ambient pressure were calculated using direct methods and compared with experimental values. Average mode Gruneisen parameters were calculated for the Raman and infrared active modes. Changes in the spectr
The present study was designed to examine the production of the Swedish tonal accents in children with language impairment and normal controls in order to verify previous findings. The productions of 25 children with linguistic impairment and their matched controls, aged 4;4-10;0 (mean age 5;11) were evaluated by ratings of fundamental frequency patterns, and by perceptual analysis by ten linguist
The aim of this study was to examine dose-dependent effects of intranasal application of neuropeptide Y (NPY) on nasal mucosal blood flow, blood content, and intranasal nitric oxide (NO) concentration. Blood flow was measured by laser Doppler flowmetry (LDF) and blood content by rhinomanometry. Mucosal biopsies were taken for investigation of Y1 and Y2 receptor mRNA expression, using the reverse t
In this paper new families of strongly universal hash functions, or equivalently, authentication codes, are proposed. Their parameters are derived from bounds on exponential sums over finite fields and Galois rings. This is the first time hash families based upon such exponential sums have been considered. Their performance improves the previously best known constructions and they can be made gene
