Noise induced hearing loss (NIHL) is one of the most important occupational disease worldwide. NIHL has been found potentiate by simultaneous carbon monoxide (CO) exposure. Free radicals have been implicated in cochlear damage resulted from the exposure to noise and due to the CO hypoxia. This study examined whether α-tocopherol administration, as a free radical scavenger, causes the attenuatio...

UNLABELLED Accurate information about type, degree, and configuration of hearing loss are necessary for successful audiological early interventions. Auditory brainstem response with tone burst stimuli (TB ABR) and auditory steady-state response (ASSR) exams provide this information. AIM To analyze the clinical applicability of TB ABR and ASSR at 2 kHz in infants, comparing responses in full-t...

BACKGROUND Bipolar disorder type I (BP-I) belongs to a spectrum of affective disorders that are expressed in many different ways and therefore can be difficult to distinguish from other conditions, especially unipolar depression, schizoaffective disorder, schizophrenia (SZ), but also anxiety and personality disorders. Since early diagnosis and treatment have shown to improve the long-term progn...

In this preliminary study, we propose an expressive and interactive research method using a developmental transformations (DvT) model multimodal art response as applied to art-based (ABR) design, specifically relating the experience of social rejection. We explored three questions: Can rejection be understood through playful interactions in DvT play? How does playing with vary solo play, play o...

Abstract Purpose With antibiotic resistance (ABR) portrayed as an increasing burden to human health, this study reviews how and what extent toxicological impacts from use are included in LCAs supplement with two novel approaches include ABR, a consequence of use, into the LCA framework. Methods We review available studies that deal aspects antibiotics evaluate these have been characterized. The...

One of the more challenging and yet unresolved issues which is paramount to the success of ATM networks is that of congestion control for Available Bit Rate (ABR) traffic. Unlike other ATM service categories, ABR provides a feedback mechanism, allowing interior nodes to dictate source rates. Previous work has demonstrated how linear control theory can be utilized to create a stable and efficien...

One of the most important applications of the Brainstem evoked response audiometry (ABR) is in the evaluation of hearing loss in children. Today the ABR is also indicated in the screening of cochleo-vestibular syndromes to detect retrocochlear lesions, to monitor patients in a coma (brain death), in monitoring the brainstem during skull base surgery, etc. Among the many BERA qualities, is its c...

Background: Central auditory processing disorders (CAPDs) tend to affect an individual’s ability understand speech, especially in difficult listening conditions.Objective: To study speech-in-noise (SIN) cases of central subjectively by Arabic Hearing Noise Test (A-HINT) and objectively Speech-evoked brainstem response (S-ABR) with ipsilateral noise.Patients Methods: Subjects included this will ...

The false negative rate of the auditory brainstem response (ABR) for the detection of vestibular schwannoma (VS; acoustic neuroma) has been reported to range from 2 to 9 percent. The introduction of magnetic resonance with gadolinium contrast (Gd MRI) may be expected to raise the false negative rate, because smaller tumors can now be detected. We present two cases that illustrate some of the co...

OBJECTIVE To use the over-complete discrete wavelet transform (OCDWT) to further examine the dual structure of auditory brainstem response (ABR) in the dog. METHODS ABR waveforms recorded from 20 adult dogs at supra-threshold (90 and 70dBnHL) and threshold (0-15dBSL) levels were decomposed using a six level OCDWT and reconstructed at individual scales (frequency ranges) A6 (0-391Hz), D6 (391-...
