Even topologically simple hyperbolic 3-manifolds can have very intricate geometry. Consider in particular a closed surface S of genus 2 or more, and the product N = S×R. This 3-manifold admits a large family of complete, infinite-volume hyperbolic metrics, corresponding to faithful representations ρ : π1(S) → PSL2(C) with discrete image. The geometries of N are very different from the product s...

AbstractBackground The receptor for advanced glycation end products (RAGE), a transmembrane belonging to the immunoglobulin superfamily, is overexpressed in pulmonary artery smooth muscle cells (PASMCs) patients with arterial hypertension (PAH) and implicated etiology of PAH. Recently, we reported that RAGE-aptamer, short single-stranded DNA directed against RAGE, inhibited an...

PURPOSE This study compared the efficacy of single-injection percutaneous peribulbar anesthesia (PBA) with a short needle with sub-Tenon's anesthesia (STA) to produce optimal operating conditions for cataract extraction in patients with complicated cataract. METHODS Two hundred patients with complicated cataract were enrolled in this prospective, double-blinded, randomized study. Adequate aki...

introduction: epinephrine-containing lidocaine is the most used anestheic drug in dentistry. the aim of this study was to investigate the hemodynamic changes following local infiltration of 2%lidocaine with 1:80,000 epinephrine in subjects undergoing orthognatic surgery under general anesthesia. methods: twenty five patients without any systemic disease participated. after general anesthesia, t...

BACKGROUND To treat cardiac injuries created by myocardial infarcts, current approaches seek to add cells and/or synthetic extracellular matrices to the damaged ventricle to restore function. Because definitive myocardial regeneration remains undemonstrated, we propose that cardiac changes observed from implanted materials may result from altered mechanisms of the ventricle. METHODS AND RESUL...

Background Steroid injection is a widespread treatment for plantar fasciitis but seems to be useful lesser extent, Platelet-rich Plasma (PRP) injections into the fascia start healing process required stop degeneration of at its root.Aim study To compare analgesic efficacy, functional outcome, degree satisfaction and improvement fascial thickness echogenicity after platelet-rich plasma versus co...

The use of self-assembled monolayers (SAMs) to improve and tailor the photovoltaic performance of plasmonic hot-electron Schottky solar cells is presented. SAMs allow the simultaneous control of open-circuit voltage, hot-electron injection and short-circuit current. To that end, a plurality of molecule structural parameters can be adjusted: SAM molecule's length can be adjusted to control plasm...
