We studied the role of the anticholinergic properties of disopyramide and quinidine in mediating the electrophysiological effects of these agents on isolated cardiac tissue. In right atria, disopyramide, quinidine, and procainamide administered alone elicited negative chronotropic responses. However, after cholinergic stimulation with physostigmine (1 X 10" M), disopyramide and quinidine produc...

Many efforts have been made to produce cellulase with better features and conditions, and filamentous fungi have played an important role in the bioprocess, growing in liquid and solid cultures with sugarcane bagasse, corn stover and others lignocellulosic materials. In the present study, Agave atrovirens fibers were partially characterized, thermal pretreated and used as support, substrate and...

Dipyrone (Dp), 4-aminoantipyrine (AA) and antipyrine (At) administered iv and Dp administered icv delay gastric emptying (GE) in rats. The participation of capsaicin (Cps)-sensitive afferent fibers in this phenomenon was evaluated. Male Wistar rats were pretreated sc with Cps (50 mg/kg) or vehicle between the first and second day of life and both groups were submitted to the eye-wiping test. GE...

Background: During de-pulping of açai (Euterpe oleracea) for juice production in the Amazonia, large amounts fibrous waste are daily discarded, a promising substrate high-value cellulose nanofibrils. Therefore, this study sought to evaluate modifications surface fibers submitted chemical pretreatment steps and compare quality nanostructured films produced with different cycles mechanical nanofi...

The action of local anesthetics, containing a tertiary nitrogen, on mammalian nonmyelinated fibers of the rabbit’s vagus nerve has been analyzed to determine whether the uncharged or the positively charged form of these compounds is responsible for their ability to block impulse conduction. The compounds studied were dibucaine, tetracaine, chlorpromazine, imipramine, and procaine. Impulse condu...

Carbon nanofiber growth on palladium particles from ethylene–oxygen mixtures was investigated with respect to thermal history. Electron microscopy, combined with focused ion beam cross-sectioning show particles sinter quickly, but can be stabilized by the addition of a short carbon deposition step at a temperature below the general reaction temperature. This step generates a thin layer of carbo...

AIM We determined if Gosha-jinki-gan, a traditional Chinese herbal mixture, reduced the presence of the tachykinins neurokinin A, neurokinin B, and substance P, as well as the transient receptor potential vanilloid 1 (TRPV1) and P2X3 purine receptors that are functionally associated with C fibers in the urinary bladder. METHODS Thirty-six female rats were fed with either a standard diet or on...
