Signs, Symptoms, and Side-Effects Presented by Different Types of COVID-19 Vaccines: A Prospective Cohort Study.

The concern about post-COVID-19 vaccine complications still remains. In addition, the evidence on Sinopharm, Sputnik V, Covaxin, and, in particular, COVIran Barekat, as well as comparisons between them by dosage after post-vaccination, is scarce. This study aimed to investigate and compare the prevalence of self-reported post-vaccination signs and symptoms following the first and second doses of different types of COVID-19 vaccines.

The Enactment of Classroom Justice Through Explicit Instruction: Deciphering the Changes in English as a Foreign Language Teachers' Perceptions and Practices.

This mixed methods research study investigated if explicit instruction could affect EFL teachers' perceptions and practices of classroom justice considering its three-dimensional conceptualization based on the social psychology theories of justice, encompassing the distributive, interactional, and procedural justice. To this end, 77 Iranian English as a Foreign Language (EFL) teachers, chosen through maximum variation sampling, attended a four-session online justice-training course. The data were collected both before and after the course intervention through close- and open-ended questionnaires.

Regenerative Medicine Under the Control of 3D Scaffolds: Current State and Progress of Tissue Scaffolds.

Currently, combining stem cells (SCs) with biomaterial scaffolds provides a promising strategy for the future of biomedicine and regenerative medicine (RG). The cells need similar substrates of the extracellular matrix (ECM) for normal tissue development, which signifies the importance of three dimensional (3D) scaffolds to determine cell fate. Herein, the importance and positive contributions of corresponding 3D scaffolds on cell functions, including cell interactions, cell migrations, and nutrient delivery, are presented.
