Objective: To investigate the chemical components and biological activities of avocado seed extract and fractions in order to determine the nutritional and pharmaceutical values of avocado seed. Methods: Various organic solvents were applied for extraction and fractionation of avocado seed. 1,1-diphenyl-2-picryl-hydrazyl, 2,2-azinobis-3-ethyl benzothiazoline-6-sulfonic acid, and DNA oxidation assays were applied for investigation of free radical scavenging activity. Nitric oxide production was measured by Griess reaction assay. Moreover, MTT assay was used to measure cancer cell growth inhibition. Results: The result indicated that the avocado seed contains (7.14 ± 0.40) g lipid/100 g, (1.67 ± 0.03) g protein/100 g, (54.0 ± 1.2) g carbohydrate/100 g, and (62.0 ± 2.3) mg gallic acid equivalent/g dried weight extract. Moreover, dichloromethane and ethyl acetate were revealed to be the highest free radical scavenging fractions with IC

Numerous studies have also revealed that students with a high level of Nomophobia have an increased risk of depression. However, few researchers are interested in examining how the association between nomophobia and depressive symptoms mediates loneliness and self-control. This study aimed to investigate, among Vietnamese High School Students, the association between nomophobia and depressive symptoms, specifically focusing on the role that loneliness and self-control play as potential mediators of that relationship. The Nomophobia Scale (NMP-Q), Depression Anxiety Stress Scale 21 (DASS-21), The UCLA loneliness scale version 3 (UCLA III), and The Brief Self-Control Scale (BSCS) were completed by 556 Vietnamese high school students. Using the PROCESS macro, mediation analyses were conducted to investigate the relationship between variables. According to our findings, nomophobia was positively associated with symptoms of depression, and loneliness and self-control partially mediated this relationship. It is suggested that methods for preventing claustrophobia and depressive symptoms be taken seriously in order to increase self-control and decrease loneliness.
