    “This study aimed to determine the effect of corporate social responsibility (CSR) on consumer satisfaction and loyalty in the Peruvian private banking sector. A total of 390 bank consumers fulfilled an online survey. It evaluated the effect of corporate social responsibility (CSR), customer satisfaction (CS), and customer trust (CT) on customer loyalty. The results suggest that CSR and customer satisfaction, through customer trust, have a positive effect on customer loyalty. The model explained 63.6% of customer loyalty. Outcomes of the bootstrapping test showed that the path coefficients were significant. The research findings may help bank managers to understand customers’ satisfaction and trust, which can create a preference and loyalty for their firms. The study’s novelty is based on the use of the partial least square structural equation modeling technique (PLS-SEM) to evaluate CSR in the financial sector in Peru. “

    Purification and Characterization of a Novel Factor of Crotoxin Inter-CRO (V-1), a New Phospholipase A2 Isoform from Crotalus durissus collilineatus Snake Venom Using an In Vitro Neuromuscular Preparation
    (MDPI, 2022-07-21) Vera-Gonzales, Corina; Arenas-Chávez , Carlos Alberto; Ponce-Soto, Luis A.; Alvarez-Risco, Aldo; Del-Aguila-Arcentales, Shyla; Davies, Neal M.; Yáñez , Jaime A.
    “The fractionation of Crotalus durissus collilineatus whole venom through an HPLC chromatographic method enabled the purification of a new V-1 neurotoxin. Inter-CRO (V-1) presents similarity in its primary structure to crotoxin B (CB), suggesting another isoform of this toxin. The aim of this study was to compare V-1 to the crotoxin complex (CA/CB) and CB to elucidate aspects related to its functionality. The homogeneity of the purified protein was confirmed with a molecular mass of 1425.45 Da, further verified by mass spectrometry. The sequence of the protein showed high similarity to other viperid snake venom PLA2 proteins. The results of this study report that V-1 is an uncharacterized novel toxin with different biological activities from CB. V-1 maintained catalytic activity but presented neurotoxic activity as observed by the 2.5-fold increase in twitch tension record compared to control values on isolated muscle cells.“

    Sustainable Fashion and Consumption Patterns in Peru: An Environmental-Attitude-Intention-Behavior Analysis
    (MDPI, 2022-08-12) Leclercq-Machado, Luigi; Alvarez-Risco, Aldo; Gómez-Prado, Romina; Cuya-Velásquez, Berdy Briggitte; Esquerre-Botton, Sharon; Morales-Ríos, Flavio; Almanza-Cruz, Camila; Castillo-Benancio, Sarahit; Anderson-Seminario, María de las Mercedes; Del-Aguila-Arcentales, Shyla; Yáñez , Jaime A.
    “This study aims to outline the influence of Environmental Attitude (EA) in Purchase Intention (PI) and Purchase Behavior (PB). The Theory of Reasoned Action (TRA) was extended by adding Environmental Concern (EC) and Perceived Environmental Knowledge (PEK) as EA predictors. A total of 396 responses from Peru were analyzed through Partial Least Squares Structural Equation Modeling (PLS-SEM). In the findings, Environmental Attitude acts as a mediator between Environmental Concern and Perceived Environmental Knowledge, and Purchase Intention. Additionally, this actual interrelationship results in a positive relationship with Purchase Behavior. Subjective Norms were not an essential predictor of Purchase Intention, which validates previous studies. Our findings suggest that Peruvian consumers prefer sustainable clothing because they are concerned with and aware of current environmental issues. Consequently, their attitude is shaped based on environmental concern and perceived environmental knowledge, resulting in an increasing intention to buy sustainable clothes, which are aimed at reducing environmental impact. The research findings may support the marketing and selling strategies of firms to show that their brands are green and can generate more interest in current and future customers. The novelty is based on using the partial least squares structural equation modeling (PLS-SEM) technique.“
