Probing the combination of erlotinib hydrochloride,an anticancer drug,and human serum albumin: Spectroscopic,molecular docking,and molecular dynamic analyses

Human serum albumin (HSA) is a globular and monomeric protein in plasma that transports many drugs and compounds. Binding of some drugs to HSA can lead to changes in its stability and biological function. We investigated the binding interactions between erlotinib hydrochloride (Erlo) and HSA. Erlo is used to treat lung, pancreatic, and some other cancers. Experimental data showed that the fluorescence emission of the protein was quenched by Erlo using a static quenching mechanism. The calculation of the binding constant, K_b (1.57 × 10⁵ M⁻¹ at 300 K), confirmed the existence of a moderate binding interaction between Erlo and HSA. The interaction was enthalpy driven, spontaneous, and exothermic. The calculated thermodynamic parameters in agreement with simulation and molecular docking data showed that van der Waals and hydrogen bond forces played an important role in the interaction process. Molecular docking results indicated that Erlo has more affinity to bind to subdomain IIA (site I) of HSA. Molecular dynamics simulation analysis showed that the protein is stable in the presence of Erlo under simulation conditions.     

Fostering equity,diversity, and inclusion in large,first‐year classes: Using reflective practice questions to promote universal design for learning in ecology and evolution lessons

Instructors can deliberately design for equity, diversity, and inclusion, including for large first‐year classes, and now instructors have added challenges given COVID‐19. Our paper explores the question: How do we integrate equity, diversity, and inclusion and universal design for learning (UDL) into first‐year, undergraduate ecology and evolution introductory lessons given the COVID‐19 pandemic? Given the large field exploring equity, diversity, and inclusion, we chose to focus on developing reflective practice question rubrics for before, during, and after lessons to encourage UDL for instructors, teaching assistants, and learners. We conducted a focus group within our team and discussed ideas related to online learning, including related pitfalls and solutions. Lastly, we created a figure to illustrate ideas and end with a general discussion. Our reflective practice questions for UDL rubrics, figure, focus group, and discussion aim to increase positive action for equity, diversity, and inclusion in the classroom and beyond.     

Supportive family relationships and adolescent health in the socio-cultural context of Iran: a qualitative study

Parents have a critical role in adolescent health. The association of adolescents'' perceptions of family relationships with adolescent health was investigated using a sample of 67 female adolescents who participated in eight focus group discussions, utilising a purposeful sampling method. All tape-recorded data were fully transcribed and content analysis was performed. Three themes were identified, namely emotional support, responsible parents and well-informed parents. With regard to some of the challenges in Iranian adolescents'' relationships with their parents, it is necessary to educate parents to be alert to their role in adolescent health.
