Alternate Nostril Breathing at Different Rates and its Influence on Heart Rate Variability in Non Practitioners of Yoga. 📎

Abstract Title: Alternate Nostril Breathing at Different Rates and its Influence on Heart Rate Variability in Non Practitioners of Yoga. Abstract Source: J Clin Diagn Res. 2016 Jan ;10(1):CM01-2. Epub 2016 Jan 1. PMID: 26894062 Abstract Author(s): Rajam Krishna Subramanian, Devaki P R, Saikumar P Article Affiliation: Rajam Krishna Subramanian Abstract: INTRODUCTION: Heart rate variability is a measure of modulation in autonomic input to the heart and is one of the markers of autonomic functions. Though there are many studies on the long term influence of breathing on HRV (heart rate variability) there are only a few studies on the immediate effect of breathing especially alternate nostril breathing on HRV. This study focuses on the immediate effects of alternate nostril breathing and the influence of different breathing rates on HRV. MATERIALS AND METHODS: The study was done on 25 subjects in the age group of 17-35 years. ECG and respiration were recorded before intervention and immediately after the subjects were asked to perform alternate nostril breathing for five minutes. RESULTS: Low frequency (LF) which is a marker of sympathetic activity increased, high frequency (HF) which is a marker of parasympathetic activity decreased and their ratio LF/HF which is a marker of sympatho/vagal balance increased immediately after 6 and 12 minutes in comparison to baseline values whereas there was no significant difference in the means of these components when both 6 and 12 minutes were compared. CONCLUSION: Immediate effects of alternate nostril breathing on HRV in non practitioners of yogic breathing are very different from the long term influence of yogic breathing on HRV which show a predominant parasympathetic influence on the heart.

Nasal cycle dominance and hallucinations in an adult schizophrenic female.

Abstract Title: Nasal cycle dominance and hallucinations in an adult schizophrenic female. Abstract Source: Psychiatry Res. 2015 Mar 30 ;226(1):289-94. Epub 2015 Jan 13. PMID: 25660663 Abstract Author(s): David Shannahoff-Khalsa, Shahrokh Golshan Article Affiliation: David Shannahoff-Khalsa Abstract: Nasal dominance, at the onset of hallucinations, was studied as a marker of both the lateralized ultradian rhythm of the autonomic nervous system and the tightly coupled ultradian rhythm of alternating cerebral hemispheric dominance in a single case study of a schizophrenic female. Over 1086 days, 145 hallucination episodes occurred with left nostril dominance significantly greater than the right nostril dominant phase of the nasal cycle. A right nostril breathing exercise, that primarily stimulates the left hemisphere, reduces symptoms more quickly for hallucinations. Article Published Date : Mar 29, 2015

Inhibition of the Zeb family prevents murine palatogenesis through regulation of apoptosis and the cell cycle.

Related Articles Inhibition of the Zeb family prevents murine palatogenesis through regulation of apoptosis and the cell cycle. Biochem Biophys Res Commun. 2018 Oct 18;: Authors: Shin JO, Lee JM, Bok J, Jung HS Abstract Mammalian palate separates the oral and nasal cavities for normal feeding, breathing and speech. The palatal shelves are a pair of maxillary prominences that consist of the neural crest-derived mesenchyme and surrounding epithelium. Palatogenesis is completed by the fusion of the midline epithelial seam (MES) after the medial edge epithelium (MEE) cells make contact between the palatal shelves. Various cellular and molecular events, such as apoptosis, cell proliferation, cell migration, and epithelial-mesenchymal transition (EMT), are involved in palatogenesis. The Zeb family of transcription factors is an essential player during normal embryonic development. The distinct role of the Zeb family has not been thoroughly elucidated to date. In mouse palate, the Zeb family factors are expressed in the palatal mesenchyme until MEE contact. Interestingly, the expression of the Zeb family has also been observed in MES, which is already fused with the mesenchymal region. The regulatory roles of the Zeb family in palatogenesis have not been elucidated to date. The purpose of this study is to determine the Zeb family effects on the cellular events. To investigate the functions of the Zeb family, siRNA targeting Zeb family was used to treat in vitro organ culture for temporary inhibition of the Zeb family during palatogenesis. In the cultured palate containing siRNA, MES was clearly observed, and E-cadherin, an epithelial marker, was still expressed. Inhibition of the Zeb family results in the suppression of apoptosis, increased cell proliferation, and defective cell migration in the developing palate. Our data suggest that the Zeb family plays multiple roles in the stimulation and inhibition of apoptosis and cell proliferation and efficient mesenchymal cell migration during palatogenesis.

Lin Chung Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2017 Nov 20;31(22):1753-1755 Authors: Ding JH, Su FR Abstract Objective:To observed the application of expanded pedicle forehead flap in nasal defect. Method:Totally 11 whole nasal defect cases in our department from June 2010 to March 2016 were treated with the expanded pedicle forehead flap. Regular follow-up was performed after operation to observe the survival condition of flaps, shape, color, texture and scar in donor site after nasal repair. Result:The expanded pedicle forehead flap and transplantation of autologous costal cartilage nasal stents were all survived, the reconstruction nasal shape was satisfied. After 1-5 years follow up, the repair using expanded forehead flap had a good color with enough blood supply, and the nasal ventilation function is well. There was only one linear scar leaved in donor site. Conclusion:Application of the expanded pedicle forehead flap is a good mothed for the treatment of whole nasal defect.
