Actividad antibacteriana de los extractos de acetato de etilo y acetona del zumo de Punica granatum L. "granada"
(Universidad Privada Norbert Wiener, 2017-11-13) Escobar Figueroa, Bernardita Jaquely; Quispe Quispe, Lidia; Félix Véliz, Luis Miguel Visitación
Punica granatum L. (“pomegranate”) has been used in traditional medicine since ancient times for the treatment of various diseases. Several studies have demonstrated its antioxidant, anti-inflammatory, antiparasitic, and antifungal properties, mainly from hydroalcoholic extracts of the peel. However, few studies have investigated pomegranate juice extracts using acetone and ethyl acetate. The aim of this research was to evaluate the antibacterial activity of acetone and ethyl acetate extracts from pomegranate juice. Antibacterial activity was assessed using the disk diffusion method. Four concentrations (200 mg/mL, 300 mg/mL, 400 mg/mL, and 500 mg/mL) of each extract were tested against Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, and Pseudomonas aeruginosa ATCC 27853. Inhibition zones were qualitatively determined according to the Durafford scale for in vitro inhibitory effects in phytotherapy and CLSI antimicrobial standards. The results indicated that the acetone extract exhibited antibacterial activity against S. aureus and E. coli. Furthermore, a comparative analysis revealed that microbial inhibition was inversely proportional to the quantification of ellagic acid. These findings highlight the potential of pomegranate juice acetone extract as a natural antimicrobial source.

Factores protectores de salud mental y estrés académico en contexto de pandemia en estudiantes de una universidad privada, Lima, 2022
(Universidad Privada Norbert Wiener, 2023-01-31) Escobar Figueroa, Bernardita Jaquely; Palacios Garay, Jessica Paola
The objective of this study was to determine the relationship between the protective factors of mental health and academic stress in the context of a pandemic in university students from a private university, Lima, 2022. For this, the basic methodology was used, whose method was the hypothetical-deductive with a quantitative approach, whose design was non - experimental, cross - sectional and correlational. And the level was descriptive and exploratory. The population consisted of 1876 undergraduate students from the Faculty of Pharmacy and Biochemistry, from I and X cycle of a private university in metropolitan Lima. The sample was obtained through a non-probabilistic convenience sampling of 127 students. The data collection was carried out through the survey, the application of two standardized instruments under the Likert Scale was used to measure both study variables. The results show that there is a significant relationship between the protective factors of mental health and academic stress in the context of a pandemic in university students from a private university, Lima, 2022 (sig = 0.028 < 0.05) and the correlation between the variables was low positive; whose coefficient value is 0.195.
