A systematic review on the effect of low-dose radiation on hearing.

Numerous studies have documented the adverse effects of high-dose radiation on hearing in patients. On the other hand, radiographers are exposed to a low dose of ionizing radiation, and the effect of a low dose of radiation on hearing is quite abstruse. Therefore, the present systematic review aimed to elucidate the effect of low-dose ionizing radiation on hearing.

Modulatory and regenerative potential of transplanted bone marrow-derived mesenchymal stem cells on rifampicin-induced kidney toxicity.

Introduction: Anti-tuberculosis agent rifampicin is extensively used for its effectiveness. Possible complications of tuberculosis and prolonged rifampicin treatment include kidney damage; these conditions can lead to reduced efficiency of the affected kidney and consequently to other diseases. Bone marrow-derived mesenchymal stem cells (BMMSCs) can be used in conjunction with rifampicin to avert kidney damage; because of its regenerative and differentiating potentials into kidney cells.

Impact of usage of personal music systems on oto-acoustic emissions among medical students.

Background: Intact hearing is essential for medical students and physicians for communicating with patients and appreciating internal sounds with a stethoscope. With the increased use of (PMSs), they are exposed to high sound levels and are at a risk of developing hearing loss. The effect of long term personal music system (PMS) usage on auditory sensitivity has been well established.

Association of auditory steady state responses with perception of temporal modulations and speech in noise.

Amplitude modulations in the speech convey important acoustic information for speech perception. Auditory steady state response (ASSR) is thought to be physiological correlate of amplitude modulation perception. Limited research is available exploring association between ASSR and modulation detection ability as well as speech perception.

Intelligibility and acoustic characteristics of clear and conversational speech in telugu (a South Indian dravidian language).

The overall goal of this study is to examine the intelligibility differences of clear and conversational speech and also to objectively analyze the acoustic properties contributing to these differences. Seventeen post-lingual stable sensory-neural hearing impaired listeners with an age range of 17-40 years were recruited for the study. Forty Telugu sentences spoken by a female Telugu speaker in both clear and conversational speech styles were used as stimuli for the subjects.
