studying crustal and upper mantel structures has been limited in the iranian plateau and there has been little work done in this field. in this paper we have a primary motive to map pn and sn velocities beneath most of the iranian plateau in order to test 3-d mantle models and to develop and test a method to produce pn and sn travel time correction surfaces that are the 3-d analogue of travel t...

INTRODUCTION Phrenic nerve stimulation (PNS) could be prevented by a silastic patch over the epicardial lead. We studied the effects in preventing PNS by placing a silastic patch directly over an epicardial lead or placing a graft around the phrenic nerve (PN). METHODS AND RESULTS Fourteen Lanyu swine were enrolled. A bipolar lead was placed epicardially on the left ventricle (LV) inferior to...

Four new complexes of the type [LCo ((DO)(DOH) pn) Cl] PF , where (DO) (DOH) pn = N , N '- propanediylbis (2, 3-butanedione2-imine3-oxirne)a nd L =morpholine (mrpln) (I), benzylamine (bzlan) (II), piperidine (pprdn)(III) and pyrrolidine (prldn) (IV) have been synthesized and characterized by elemental analyses and spectroscopic methods. Approximate values of the angular-overlap parameter, ?, ...

Seasonal control of flowering through responsiveness to daylength shows extreme variation. Different species flower in response to long days or short days (SDs), and this difference evolved several times. The molecular mechanisms conferring these responses have been compared in detail only in Arabidopsis thaliana and rice (Oryza sativa) and suggest that a conserved pathway confers daylength res...

BACKGROUND Recent studies suggest an increased frequency of peripheral neuropathy (PN) in Parkinson's disease patients (PD) (Toth et al. 2010). The aim of our study is to verify the increased frequency of PN in our group of PD patients compared to an age-matched control group. We sorted patients according to the duration of L-DOPA treatment, L-DOPA dosage, and age below or over 50 years. METH...

Abstract The young, compact, very high surface brightness but low excitation planetary nebula (PN) BD+30°3639 is one of the few PNe that have been reported to exhibit 21 cm H i emission line. As part a long-term program search for circumstellar atomic hydrogen, we observed feature toward with Five-hundred-meter Aperture Spherical radio Telescope (FAST). Assuming direct association between PN an...

OBJECTIVES To analyzed the therapeutic results for patients with overlooked iatrogenic ureteral injuries after gynecological surgery, treated at the department since 1990. Before the era of endourology, ureteral injuries were operated on immediately after making a diagnosis. This approach was changed after the popularization of percutaneous nephrostomy (PN) and ureteral stenting using a JJ sten...

Adult spinal motoneurons can regenerate their axons into a peripheral nerve (PN) graft following root avulsion injury if the graft is implanted immediately after the lesion is induced. The present study was designed to determine how avulsed motoneurons respond to a PN graft if implantation takes place a few days to a few weeks later. Survival, regeneration, and gene expression changes of injure...

OBJECTIVE To analyze the outcome of children with short bowel syndrome (SBS) who required long-term parenteral nutrition (PN). STUDY DESIGN Retrospective analysis of children (n=78) with SBS who required PN >3 months from 1975 to 2000. STATISTICS univariate analysis, Kaplan-Meier method, and Cox proportional regression model were used. RESULTS We identified 78 patients. Survival was bette...
