One of the most significant medicinal plants used to treat numerous illnesses is Swertia chirayita. The present study demonstrated the compositional analysis of the Swertia chirayita (S. chirayita) plant using an emerging and non-destructive laser-induced breakdown spectroscopy (LIBS) technique. Mg, Ca, K, Fe, Sr, Cr, and Na were verified as necessary elements by the optical emission investigations, while Al, Ti, Si, Ba, Mn, and Li were non-essential. Using the Boltzmann plot technique with stark broadening parameters, plasma temperature and electron number density were calculated in the range of (10,000-12,000) K ±1000 K and (1.5-1.8) × 1017 cm-3, respectively. Finally, compositional analysis was carried out using calibration-free (CF-LIBS) analysis and results were compared with ICP-MS. It was observed that the concentration of Ca and Fe is higher than other detected elements. All the toxic elements are found to be within the safe limit. So, this medicinal plant can be used to cure a variety of diseases that arise due to the deficiency of these elements.

Importance: Investigating rural-urban and regional differences in the association between dual sensory loss (concurrent hearing and vision loss) and depression may highlight gaps in sensory loss research and health care services, and by socioeconomic status. Whether urbanicity and region may modify associations between sensory loss and depression is unknown.
Objective: To describe the rural-urban and regional differences in the association of dual sensory loss with depression among older adults.

Plant-based foods with low methionine contents have gained increasing interest for their potential health benefits, including neuroprotective effects. Methionine restriction (MR) linked to a plant-based diet has been shown to mitigate neurodegenerative diseases such as Alzheimer's disease (AD) through mechanisms that involve the gut microbiota. In this study, a 16-week MR diet (0.

Compositionally complex doping of spinel oxides toward high-entropy oxides is expected to enhance their electrochemical performance substantially. We successfully prepared high-entropy compounds, the oxide (ZnMgCoCu)FeO (HEOFe), lithiated oxyfluoride Li(ZnMgCoCu)FeOF (LiHEOFeF), and lithiated oxychloride Li(ZnMgCoCu)FeOCl (LiHEOFeCl) with a spinel-based cubic structure by ball milling and subsequent heat treatment. The products exhibit particles with sizes from 50 to 200 nm with a homogeneous atomic distribution.
