The purpose of this study was to determine whether clicks presented in rarefaction or condensation modes produce more accurate diagnostic information. Subjects were 20 consecutive patients who were seen at the Mayo Clinic for unilateral acoustic neuromas. The nontumor ear served as a control to minimize intersubject variability in the latencies. A standard audiologic evaluation was followed by ...

Introduction: Multiple sclerosis (MS) has been recognized as a common neurodegenerative disease that occurs after an Auto reactive T cells against myelin antigens.  Demyelination and inflammation are the main features of this disease. The anti-inflammatory and neuroprotective roles of bone marrow-derived mesenchymal stem cells (BM-MSCs) have been considered as a suitable tre...

background: to determine if the glidescope® videolaryngoscope (gvl) could attenuate the hemodynamic responses to orotracheal intubation compared with conventional macintosh laryngoscope. objectives: the aim of this relatively large randomized trial was to compare the hemodynamic stress responses during laryngoscopy and tracheal intubation using gvl versus mcl amongst healthy adult individuals r...

We developed the Physics Inventory of Quantitative Literacy (PIQL) to assess students’ quantitative reasoning in introductory physics contexts. The PIQL includes several “multiple-choice-multiple-response” (MCMR) items (i.e., multiple-choice questions for which more than one response may be selected) as well traditional single-response items. In this paper, we discuss differences performance on...

This study looks at the communication between users concerning health risks, with the aim of exploring their use of fora and assessing whether participants establish a niche with like-minded users during these exchanges. By integrating a corpus linguistic approach with content analysis and multiple studies on computer mediated health discourse, this study analyses the intense attention paid to ...

Two studies are reported in which the threshold estimates from auditory steady-state response (ASSR) tests are compared to those of click- or toneburst-evoked auditory brainstem responses (ABRs). The first, a retrospective review of 51 cases, demonstrated that both the click-evoked ABR and the ASSR threshold estimates in infants and children could be used to predict the pure-tone threshold. The...

The feasibility of recording bone-conducted auditory brainstem responses (ABRs) to 500-Hz and 2000-Hz tone bursts and clicks was investigated in normal-hearing adults. For all 3 stimuli, responses were detectable in all subjects at 30 dB nHL. At 20 dB nHL, the tone burst responses were detectable in 80-87% of the subjects, demonstrating that even the responses to 500-Hz tone bursts were relativ...

Speech auditory brainstem responses (speech ABR) reflect activity that is phase-locked to the harmonics of the fundamental frequency (F0) up to at least the first formant (F1). Recent evidence suggests that responses at F0 in the presence of noise are more robust than responses at F1, and are also dissociated in some learning-impaired children. Peripheral auditory processing can be broadly divi...

Multiple Solutions: A Key to Strengthening the Generalization Skill in Mathematic-Like Thinking   Z. Rahimi* E. Talaa'ee, Ph.D.** E. Reyhaani, Ph.D.*** H. Fardaanesh, Ph.D.****   Emphasizing multiple solutions can help with the strengthening of the generalization skill. To test this hypothesis, a group of high school students in math and experimental sciences was selected in or...
