Objectives We retrospectively evaluated a chart review of 3,525 patients for any acute disturbance. A total 1,504 with vestibular syndrome (AVS) received an instrumental assessment within 72 h from the onset symptoms using simultaneously combination ocular vestibular-evoked myogenic potential (oVEMPs), cervical (cVEMPs), video head-impulse test (vHIT), and subjective visual vertical (SVV) were ...

The parameters affecting the production of pectate lyase from P. polymyxa N10 were studied using the response surface methodology agitation rate (X1, 100-300 rpm), temperature (X2, 25-45 o C) and pH (X3, 5.5-9.5). The most significant factors influencing enzyme production were temperature and pH. The second order polynomial regression model obtained was fitted and found adequate, with an R 2 of...

Os potenciais evocados miogênicos vestibulares (VEMP) são respostas eletrofisiológicas que conseguem fornecer informações dos órgãos otolíticos sáculo (cVEMP), utrículo (oVEMP) e do nervo vestibular. Com o envelhecimento, mudanças morfológicas podem afetar funcionamento sistema O objetivo foi verificar efeito envelhecimento sobre a função vestibular, por meio exame VEMP. Estudo transversal, ana...

In 1998-2002, Argentina experienced what the government described as a “great depression.” Using the “Great Depressions” methodology developed by Cole and Ohanian (1999) and Kehoe and Prescott (2002), we find that the primary determinants of both the boom in Argentina in the 1990s and the subsequent depression were changes in productivity, rather than changes in factor inputs. The timing of eve...
