Background: Life, nowadays, is full of stress, and stress become almost an integral part of our daily routine life. It affects the every aspect of our life and leads to development of stress-related disorders such as hypertension, diabetes mellitus, and many more diseases. Aims and Objective: The aim of this study was to investigate whether regular practice of Ujjayi Pranayama for 3 months can reduce the cardiovascular hyperreactivity (stress) induced by cold pressor test. Materials and Methods: A total of 60 young healthy individual (35-male, 25-female) were selected who performed Ujjayi Pranayama for duration of 3 months. The cardiovascular hyperreactivity is recorded before and after the regular practice of Ujjayi Pranayama. Results: Regular practice of Ujjayi Pranayama for 3 months significantly reduces the cardiovascular hyperreactivity in basal blood pressure (BP), rise in BP after 1 min of cold stress, pulse rate, and rate of respiration. Initially, there were 25 hyperreactors to cold pressor test which reduce to 11 after practicing Pranayama for 3 months. The remaining subjects also reduce their reactivity to cold stress. Conclusion: Ujjayi Pranayama can significantly decreases the stress induced changes in cardiovascular parameters because this leads to cardiovascular autonomic balance toward parasympathetic side and cortico-hypothalamo-medullary inhibition.

BACKGROUND Pranayama is a Yogic technique in which breathing is controlled voluntarily. Aim-To study the effect of yoga exercise ("Pranayama" breathing exercise) and meditation on cardiorespiratory parameters in young healthy volunteers.

Brainstem Evoked Response Audiometry (BERA), being the most sensitive and specific test of hearing assessment in new-borns is beneficial for early detection of hearing impairment in high risk infants. BACKGROUND AND OBJECTIVEBERA was recorded in all high risk infants as defined by JCIH, 2007 criteria for identification of hearing deficits and to identif y severity of hearing loss.

Background: This study is concerned with the changes of electroencephalographic (EEG) from immature neonatal to the development of mature normal EEG pattern with special attention given to the infant's age (0-12 months), growth, and developmental level. Aims and Objectives: The objective is to study serially development of specific EEG patterns in infants, i.e., from birth to 12 months of age. Materials and Methods: This is a longitudinal follow-up study conducted on 50 (27 female and 23 male) healthy, normal, full-term infants delivered vaginally in the Department of Obstetrics and Gynaecology, Netaji Subhash Chandra Bose, Medical College and Hospital, Jabalpur, Madhya Pradesh, starting from the birth to 12 months of age in normal environment in the Department of Physiology EEG-unit for 60 min in 5 different visits, i.e., at birth/0-2 week, 3-month, 6 months, 9 months, and 12 months. Result: This study provides clearly established strong changes in EEG wave pattern and their appearances with increased speed of response, which are most clearly visible from the time of birth, 3-6 months, and at 12 months of age. These marked changes of EEG may be associated with language and other motor milestone development. Conclusion: Sleep characteristics during this period may have predictive value in the assessment of future neurodevelopmental conditions. The study also concluded that the percent of time that infants spend in sleep decreased sharply from 3 to 6 months, but the sleep cycle becomes more defined. The duration of infant's sleep did not change significantly across the 1 st year, but the percent of time spent in active sleep is markedly decreased, i.e., ≤25%, and the sleep progresses toward maturity which is confirmed by the establishment of continuity, symmetrical synchronous EEG pattern, and the disappearance of neonatal trace alternant, along with the focusing on measurement of weight and head circumference.
