Effect of Trataka (A Yogic Cleansing Technique) on Post-Covid Cognitive Impairments in Elders

Background: People who have survived COVID-19 frequently complain of cognitive dysfunction, which has been described as brain fog. Early reports describing a dysexecutive syndrome after COVID-19 and has considerable implications for occupational, psychological, and functional outcomes. It is well known that elders may be particularly susceptible to cognitive impairment after critical illness. Trāṭaka (a yogīc cleansing technique) is one of the Yogā practices which is considered to improve cognitive functions. The objective of this study was to determine whether Trāṭaka practice enhances the cognitive functions of the post covid elderly subjects. Material and Methods: Thirty elders who had enrolled in a thirty days Trāṭaka practice program. Their age ranged between 60 and 80 years (group average ±S.D., 68.5±6.3 years). Those who have any chronic illness and mental illness, and those who are not willing to participate were excluded. Trāṭaka intervention is given for 30 days, 1hour/day. At baseline and following thirty days, all participants completed DLST and SLCT. Results: Trāṭaka intervention showed significant change in DLST scores, increase (P-value< 0.000) in total attempted score, significant increase (P-value<0.000) in net score, significant reduction in wrongly attempted score (P-value<0.000). Significant change in SLCT scores, significant increase (P-value<0.000) in total attempted score, Similarly, significant increase (P-value<.000) in net score, significant reduction in wrongly attempted score (P-value<0.000). Conclusion: The thirty days Trāṭaka intervention was successful in enhancing the cognitive functions among post-covid elders

Development and validation of a Yoga module for Primary dysmenorrhoea

Menstrual pain without organic pathology is considered to be primary dysmenorrhoea. Dysmenorrhoea refers to the occurrence of painful menstrual cramps of uterine origin. It is a common gynaecological condition with considerable morbidity affecting majority of the adolescent girls, yet which is under diagnosed and under treated. Yoga can be considered as a simple and safe management tool for Primary Dysmenorrhoea. Studies have reported the beneficial role of Yoga in alleviating the symptoms of Primary dysmenorrhoea; however, a validated Yoga module for Primary dysmenorrhoea is unavailable. This study developed and validated an integrated Yoga module (IYM) for Primary dysmenorrhoea. Methods: The IYM was prepared after a thorough review of classical Yoga texts and previous findings. Twenty experienced Yoga experts, who fulfilled the inclusion criteria, were selected validating the content of the IYM. A total of 38 practices were included in the IYM, and each practice was discussed and rated as (i) not essential, (ii) useful but not essential, and (iii) essential; the content validity ratio (CVR) was calculated using Lawshe’s formula. Results: Data analysis revealed that of the 38 IYM practices, 18 exhibited significant content validity (cut-off value: 0.42, as calculated by applying Lawshe’s formula for the CVR). Conclusion: The IYM is valid for Primary dysmenorrhoea, with good content validity. However, future studies must determine the feasibility and efficacy of the developed module

The Effect of 3-week’s Yoga therapy program on clinical outcomes in patients with Parkinson’s disease

Background: Parkinson's disease, according to the WHO, has a variety of non-motor side effects in addition to its motor symptoms (cognitive impairment, mental health disorders, pain, and other sensory disturbances). The progression of these symptoms and their implications affects functioning and quality of life greatly, resulting in high rates of impairment and care demands, as well as stress and strain on caregivers. Material & Methods: A total of 31 PD patients were included in this investigation. The Integrated Approach of Yoga Therapy was applied to all patients who met the inclusion criteria (IAYT). Parameters were taken twice, once on the day of admission and other when they were leaving the residence on completion of the program. Data was evaluated using a pre-test and post-test design. Dependent Variable: Pulse rate, Respiratory rate, Systolic Blood Pressure, Diastolic Blood Pressure, Breath Holding time and BMI. Results: A total of 31 subjects participated in the study 31 subjects completed the study. After 21 days of integrated Yoga therapy program, it showed that significant reduction in (P< 0.05) in Systolic and diastolic Blood pressure, respiratory rate and significant improvement is seen in breath holding time (BHT), but there were no changes in BMI (P> 0.05). Conclusion: The three-week yoga programmed was able to dramatically enhance clinical results in Parkinson's disease and self-reported medication reduction without aggravating symptoms

Application of Kalman Filter to prognostic method for estimating the RUL of a Bridge Rectifier

Abstract—Prediction of the Remaining Useful Lifetime (RUL) of the system brings down the maintenance cost, downtime and also helps to take corrective measures. This results in avoiding catastrophic events. In this Paper, The RUL prediction is done based on KalmanFilter approach with dynamic curve fitting. The desired state (which is synthetic data) of the system is estimated based on a second order Kalman Filter, where Newtonian Kinematic model is used in tracking the significant feature state of the system. The dynamic curve fitting is done based on Least Square Error Sense method. The dynamically fitted curve is extrapolated until the failure threshold is reached and subsequently RUL is estimated. The algorithm thus developed is validated by a single phase full wave bridge rectifier analogous to aircraft Transformer Rectifier Unit (TRU), to obtain the real time significant feature data. The experimental results are compared with those of developed algorithms and results show Kalman filter based algorithm is ~95% accurate

Structural and Magnetic Properties of polycrystalline La2NiMnO6 thin

Polycrystalline thin films of La2NiMnO6 (LNMO) are deposited successfully on SiO2/Si substrates using pulsed laser deposition technique. Structural characterization using X-ray diffraction confirms the formation of a single phase with P2(1)/n space group. Cross-sectional FE-SEM shows the film thickness similar to 195 nm. The deposition temperature and the oxygen pressure played a crucial role determining the crystallization behavior and the magnetic transition temperatures. The ferromagnetic transition temperature is achieved to be similar to 277 K by optimizing the deposition conditions

Magnetic ground state of the multiferroic hexagonal LuFeO3

The structural, electric, and magnetic properties of bulk hexagonal LuFeO3 are investigated. Single phase hexagonal LuFeO3 has been successfully stabilized in the bulk form without any doping by sol-gel method. The hexagonal crystal structure with P6(3)cm space group has been confirmed by x-ray-diffraction, neutron-diffraction, and Raman spectroscopy study at room temperature. Neutron diffraction confirms the hexagonal phase of LuFeO3 persists down to 6 K. Further, the x-ray photoelectron spectroscopy established the 3+ oxidation state of Fe ions. The temperature-dependent magnetic dc susceptibility, specific heat, and neutron-diffraction studies confirm an antiferromagnetic ordering below the Neel temperature (T-N) similar to 130 K. Analysis of magnetic neutron-diffraction patterns reveals an in-plane (ab-plane) 120 degrees antiferromagnetic structure, characterized by a propagation vector k = (0 0 0) with an ordered moment of 2.84 mu(B)/Fe3+ at 6 K. The 120 degrees antifferomagnetic ordering is further confirmed by spin-orbit coupling density functional theory calculations. The on-site coulomb interaction (U) and Hund's parameter (J(H)) on Fe atoms reproduced the neutron-diffraction Gamma(1) spin pattern among the Fe atoms. P-E loop measurements at room temperature confirm an intrinsic ferroelectricity of the sample with remnant polarization P-r similar to 0.18 mu(C) cm(2). A clear anomaly in the dielectric data is observed at similar to T-N revealing the presence of magnetoelectric coupling. A change in the lattice constants at T-N has also been found, indicating the presence of a strong magnetoelastic coupling. Thus a coupling between lattice, electric, and magnetic degrees of freedom is established in bulk hexagonal LuFeO3
