Background Antibiotic resistance is a rapidly increasing global emergency that calls for action from all of society. Intestinal multidrugresistant (MDR) bacteria have spread worldwide with extended-spectrum beta-lactamase (ESBL) -producing Enterobacteriaceae (ESBL-PE) as the most prevalent type. The millions of travelers annually visiting regions with poor hygiene contribute substantially to th...

Maximum Satisfiability (MaxSAT) is a well-known optimization version of Propositional Satisfiability (SAT) that finds a wide range of practical applications. This work describes and evaluates the Maximum Satisfiability using the Core-Guided approach solver (MSCG), which is a robust MaxSAT solver that participated in the MaxSAT Evaluation 2014.

Articolul analizează cinematica roţii de orientare a unui robot mobil planar constituit dintr-o platformă orizontală şi două roţi convenţionale. Vitezele şi acceleraţiile caracteristice ale sistemului mecanic neolonom sunt stabilite pe baza unor relaţii matriceale de conectivitate. Cunoscând mişcarea celor două roţi motoare, se obţin expresii şi grafice pentru unghiul relativ de rotaţie şi trai...

This article is divided into six sections that are related to six commonly used operations for surgery on the maxillary sinus. The authors discuss maxillary sinoscopy, the Caldwell-Luc procedure, extended middle meatus antrostomy, endoscopic maxillary sinus antrostomy, minimally invasive sinus technique, and balloon sinus procedures. In each of these procedures, the authors discuss potential co...

This study was performed to determine the effect of forced swimming on the vascular responsiveness of the rat superior mesenteric artery to phenylephrine, focusing on the involvement of locally produced substances. Repeated but not single sessions of forced swimming exercise reduced the vasoconstrictor potency of phenylephrine in the studied arteries, regardless of the presence of intact endoth...

Several techniques have been proposed to prevent hypotension in obstetric patients. Ephedrine and phenylephrine are individually used to prevent maternal hypotension; however, each has its own drawbacks. Some researchers have reported that the infusion of combined ephedrine and phenylephrine immediately after spinal anesthesia for cesarean delivery reduces the incidence of maternal hypotension....

BACKGROUND A toxic dose of bupivacaine produces vasodilation in isolated aortas. The goal of this in vitro study was to investigate the cellular mechanism associated with bupivacaine-induced vasodilation in isolated endotheliumdenuded rat aortas precontracted with phenylephrine. METHODS Isolated endothelium-denuded rat aortas were suspended for isometric tension recordings. The effects of nif...
