BackgroundIn this study, the effects of individuals' digital obesity and phubbing behaviors on their life satisfaction were investigated by latent profile analysis (LPA) method. LPA is a statistical technique used to identify unobserved subgroups within a population based on individuals' responses to various observed variables.MethodsThe present study was conducted in a correlational cross-sectional descriptive design between November 2023- January 2024. Digital obesity scale, phubbing scale, life satisfaction scale were used in this study.ResultsAs a result of LPA, Class 1 (Low Digital Addicts) has the lowest arithmetic mean in all indicators. When life satisfaction was analyzed on the basis of the classes, it was found out that Class 2 (High Digital Addicts), which was collected in the group with high levels of digital obesity and phubbing, had lower life satisfaction. Considering the demographic levels of individuals according to class level, it was concluded that high digital addiction was more common among individuals with secondary and postgraduate education.ConclusionsIn the present study, two classes were found as a result of LPA. In the analysis, Class 1(Low Digital Addicts) was found to have the lowest arithmetic mean in all indicators. On the other hand, when life satisfaction was analyzed according to the classes, it was detected that Class 2 (High Digital Addicts) life satisfaction was lower in the group with high levels of digital obesity and phubbing. In the study, the life satisfaction of class 1, which is characterized as low digital addicts, was found to be higher. Longitudinal studies on digital addictions affecting life satisfaction are recommended.

Cadmium (Cd) is the most dangerous and prevalent one which has tremendous impacts on global food security. Although chrysin (Chr) has been extensively studied in Cd stressed animal system, the role of this valuable flavonoid in plants is yet to be clarified. Therefore, this study was designed to determine the effects of different doses of Chr (0, 50, 150 and 300 mu M) on some physiological, biochemical and gene expression in pepper grown under Cd stress (0 and 50 mM Cd). Cd stress significantly arrested relative water, proline, essential nutrients and phytohormones content when compared to non-stressed plants. However, Cd stress caused significant enhancement of hydrogen peroxide (H2O2), melondialdehyde (MDA), and tissue electrolyte leakage (EL) and reduction of enzymatic antioxidants like superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) and peroxidase (POD), and expression of photosystem II (PSII) and aquaporin (AQPs) related transcripts compared to non-stressed plants. Compared to Cd stress, Chr positively regulated the formation of H2O2, MDA and %EL, antioxidant enzyme activity, as well as accelerated the synthesis of indole-3-acetic acid (IAA), gibberellic acid (GA) and cytokinins (CK) and reduced the level of abscisic acid (ABA), which was significantly increased by Cd stress. In addition, Chr demonstrated enhanced expression of CaPsbB, CaPsbD, CaPsb1 and CaPsb2, CaPIP1-2 and CaTIP5-1 in both root and shoots and when compared to Cd stressed plants. The findings obtained at the end of the study show that Chr is very important for alleviation of Cd toxicity in pepper plants.
