    Release behaviour of iron and zinc in different textured soil and its distribution in rice plant (Oryza sativa L.) in North West of India
    (Slovak University of Agriculture in Nitra, 2023) Jangir, Chetan Kumar; Sangwan, P.S.; Panghaal, Dheeraj; Kumar, Sandeep; Meena, Ram Swaroop; Bharti; Jat, Ram Dhan; Singh, Narendra
    The present study aimed to assess the relationship of soil properties with extractable zinc (Zn) and iron (Fe) in soil as well as rice plant at different incubation period. The soil and plant samples were collected from 10 districts (Yamuna Nagar, Sonipat, Jind, Panipat, Karnal, Panchkula, Kaithal, Rohtak Ambala, and Kurukshetra) of RWCS (Rice wheat cropping system) of northwest Haryana of India. The effects of soil properties especially soil texture with the micronutrient in soil and rice plant at different incubation period have not been well studied. In the lab-cum-survey study, the analysis of grain samples collected from different districts of Haryana under varied soil texture showed a positive correlation between Zn/Fe concentration in grain and mean release rate of Zn/Fe in soil (Zn � 0.80; Fe � 0.98). The highest Fe concentration in grain was found in clayey soils (59.74�60.41 mg/kg) having a maximum mean soil Fe release rate (17.98�18.03 mg/kg). Likewise, the highest Zn concentration in grain was recorded in clayey soils (29.71�30.57 mg/kg) of Yamuna Nagar and Panchkula, which has the highest mean soil Zn release rate (1.03�1.14 mg/kg). Univariate and multivariate analysis under principal component analysis (PCA) was carried out to determine the linear relationship between soil properties and extractable soil Zn and Fe concentration as well correlogram correlation matrix using for soil properties with grain Zn and Fe concentration. Hence, the study concluded that the detection for Zn and Fe are more successful in soils with a higher proportion of clay particles than in sandy soils. Plant uptake potential is highly influenced by soil micronutrient interactions with soil properties, especially soil texture, which can be predicted by extractable soil micronutrients. � 2023 Slovak University of Agriculture in Nitra.

    The effect of yoga on pulmonary function in patients with asthma: A meta-analysis
    (Churchill Livingstone, 2023) Anshu; Singh, Narendra; Deka, Sangeeta; Saraswati, Priyanka; Sindhwani, Girish; Goel, Arun; Kumari, Ranjeeta
    Background: Asthma is one of the most common non-communicable diseases. Yoga with physical postures, breathing exercises, meditation, and relaxation may play an essential role in the complementary management of lower respiratory diseases. The study aimed to evaluate the impact of yoga (posture, breathing exercises, and meditation) on pulmonary function tests, asthma control tests, and health-related quality of adult asthmatic patients. Methods: MEDLINE, PubMed, Embase, Cochrane, Scopus, Google Scholar, ResearchGate, Clinical Key, and Academia electronic search engines were explored to search the relevant literature. The present study included adult asthmatic patients (age ?18 and 60 years) with mild to moderate asthma, per GINA (Global Initiative for Asthma) guidelines. The effect of yoga was assessed on the following outcomes; pulmonary function tests, including FeV1 (Forced expiratory volume 1 s), FVC (Forced vital capacity), FeV1/FVC, peak expiratory flow rate (PEFR), health-related quality of life, and asthma control test. A fixed-effect model was applied to compute significance for statistical heterogeneity. P-value <0.05 was considered for statistical significance. Results: Finally, fifteen articles were included for meta-analysis. The forest plot for overall effect of yoga intervention and usual care favors the yoga intervention for improvement in pulmonary function as FeV1 (SMD = 0.96, CI = 0.77�1.14, I2 = 54%), FVC (SMD = 0.35, CI = 0.14�0.55, p = 0.11, I2 = 50%), Fev1/FVC (SMD = 0.18, CI = ?0.38-0.02, p = 0.02, I2 = 50%), PEFR (SMD = 0.38, CI = 0.18�0.58, p = 0.0003, I2 = 0%), asthma control test (SMD = 0.16, CI = 0.15�0.48, p = 0.31, I2 = 86%) and health-related quality of life (SMD = 0.26, CI = 0.18�0.34, p = 0.02, I2 = 51%) of asthmatic patients. Conclusion: This meta-analysis provides a moderate level of evidence regarding yoga as a complementary therapy in managing mild to moderate asthmatic patients. It also adds to the current knowledge of the same. � 2022 Elsevier Ltd

    Variability of air quality and aerosol over Indian region during 2003�2012
    (Springer, 2023) Kumar, Sanjay; Singh, Narendra; Singh, R.P.; Siingh, Devendraa
    The Indo-Gangetic basin is one of the biggest, most populated and polluted regions in the world. Satellite- and ground-based data show strong seasonal variability of aerosol loading with a maximum during pre-monsoon (summer) season. In this study, decadal (2003�2012) variability of aerosol optical depth (AOD) derived from AERONET measurements over Kanpur is presented which indicates maximum AOD during 2003 and minimum during 2012. The aerosol size distribution (ASD) exhibits an increase in the radius and a decrease in the width of distribution. It shows an enhancement during 2003 and 2010 and diminished values during 2004, 2007, 2009 and 2011. The ASD is found to show a peak during summer season (pre-monsoon) throughout 2003�2012 only except the years 2008 and 2011. Moreover, for years 2008 and 2011 ASD showed a peak value during a monsoon month (July). Changes in the spectrum of ASD are explained in terms of surface temperature and precipitation. Seasonal variation of aerosol radiative forcing and its climatic impacts have also been discussed. � 2022, Indian Association for the Cultivation of Science.
