iontophoresis of epinephrine for assessment of neuromuscular junction response is a new technique that can improve diagnose of neuromuscular dysfunction. the purpose of this study was to investigate the effects of iontophoresis of epinephrine on neuromuscular junction response. iontophoresis of epinephrine solution (1mg/ml), sodium chloride, calcium gluconate, epinephrine with sodium chloride a...

Given a pair of distinct vertices u, v in a graph G, we say that s is a junction of u, v if there are in G internally vertex disjoint directed paths from s to u and from s to v. We show how to characterize junctions in directed acyclic graphs. We also consider the two problems in the following and derive efficient algorithms to solve them. Given a directed acyclic graph G and a vertex s ∈ G, ho...

An undirected graphical model is a joint probability distribution defined on an undirected graph G∗, where the vertices in the graph index a collection of random variables and the edges encode conditional independence relationships amongst random variables. The undirected graphical model selection (UGMS) problem is to estimate the graph G∗ given observations drawn from the undirected graphical ...

tuberculous spondylitis is not an uncommon disease of the spine. near one percent of all cases of spinal tuberculosis (tb) involves craniocervical junction. hypoglossal nerve palsy is not an uncommon neurological finding, but isolated involvement of the hypoglossal nerve is rare and limited to case reports or small case series. here, we report a case of craniocervical junction tuberculosis pres...

background: recent researches have led to find strategies to prevent relapse and to improve survival for gastric cancer patients, including preoperative neo-adjuvant approaches. however, the efficacy of some neo-adjuvant regimens including 5-fluorouracil, cisplatin, and docetaxel have been less investigated. the present study evaluated the outcome and mid-term survival of patients with gastric ...

Gap junctions mediate cell-cell communication in almost all tissues, but little is known about their regulation by physiological stimuli. Using a novel single-electrode technique, together with dye coupling studies, we show that in cells expressing gap junction protein connexin43, cell-cell communication is rapidly disrupted by G protein-coupled receptor agonists, notably lysophosphatidic acid,...

To elucidate slow dynamics in glassy materials, we introduce the figure-8 model in which N hard blocks undergo Brownian motion around a circuit in the shape of a figure 8. This system undergoes kinetic arrest at a critical packing fraction phi=phi g<1 , and for phi approximately phi g long-time diffusion is controlled by rare, cooperative, "junction-crossing" particle rearrangements. We find th...
