BACKGROUND The objective of this study is to analyze the adrenoceptor and calcitonin-gene related peptide receptor in the isolated striated urethral sphincter from a male rabbit. METHODS The striated urethral sphincter preparations were suspended in 2ml tissue chamber filled with Krebs Ringer solution, and the changes of isometric twitch contraction induced by electrical field stimulation (EF...

We have observed the linear polarization of 450 μm continuum emission from the Galactic center, using a new polarimetric detector system that is operated on a 2 m telescope at the South Pole. The resulting polarization map extends ∼ 170 pc along the Galactic plane and ∼ 30 pc in Galactic latitude, and thus covers a significant fraction of the central molecular zone. Our map shows that this regi...

We show that, on a p-elliptic hypermap, an automorphism is of maximal order p(1 + 2g=(p ? 1)) if o() = pm where p and m are coprime, and that the bound becomes 2pg=(p ? 1) otherwise. We classify the automorphism groups of p-elliptic hypermaps and give an exhaustive list when p is g + 1 or 2g + 1. Finally, the Klein map is shown to be the only regular map admitting an automorphism of prime order...

Misra, Prigogine and Courbage (MPC) demonstrated the possibility of obtaining stochastic Markov processes from deterministic dynamics simply through a ”change of representation” which involves no loss of information provided the dynamical system under consideration has a suitably high degree of instability of motion. From a mathematical point of view, MPC theory is a theory of positivity preser...

O Objective: Many biological studies have been done to determine the activity of medicinal plants on gastrointestinal function. Since acetylcholine is the major transmitter involved in the gastrointestinal motility and there are some evidences regarding the cholinergic modulatory effect of hops extract, in the present study spasmolytic and antispasmodic action of hops(Humulus lupulus) on acetyl...

seeds of moringa peregrina (forssk.) fiori. (moringaceae) is widely used in south east of iran for gastrointestinal disorders. however, so far there is no pharmacological evidence for antispasmodic activity of this plant extract. therefore, the aim of this research was to investigate antispasmodic activity of m. peregrina on rat isolated ileum contraction. hydroalcoholic extract was obtained by...

We establish a lower estimate for the Kobayashi-Royden infinitesimal pseudometric on an almost complex manifold (M, J) admitting a bounded strictly plurisubharmonic function. We apply this result to study the boundary behaviour of the metric on a strictly pseudoconvex domain in M and to give a sufficient condition for the complete hyperbolicity of a domain in (M, J).

BACKGROUND Multisite atrial pacing (MAP) was introduced to improve atrial electrical synchrony and prevent recurrence of atrial fibrillation (AF). METHODS AND RESULTS In the present study there were 57 patients with sinus node disease, AF recurrence and prolonged P-wave on ECG with 2 MAP modalities. In all patients 1 lead was implanted in the coronary sinus (CS) ostium area. In the right atri...

We present an efficient quantum algorithm to measure the average fidelity decay of a quantum map under perturbation using a single bit of quantum information. Our algorithm scales only as the complexity of the map under investigation. Thus for those maps admitting an efficient gate decomposition, it provides an exponential speedup over known classical procedures. Fidelity decay is important in ...

In this paper a multi-hop infrastructure based wireless mesh network (WMN), consisting of mesh access points (MAPs) and mesh client (flow) with a hierarchical architecture is considered. The association of each flow-MAP and the multi-hop backhaul routing from the associated MAP to the Gateway, determine the available bandwidth for admitting or rejecting a flow. The main focus of this paper is t...
