Reactive oxygen species induced by SARS-CoV-2 infection can induce EMT in solid tumors: Potential role of COVID-19 in chemo-resistance and metastasis.

The coronavirus disease 2019 (COVID-19) pandemic has raised discussion over the connection between viral infections and the biology of cancer. Research has investigated the relationship between signaling pathways stimulated by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that may be involved in the progression of cancer, resistance to chemotherapy, and metastasis. However, the exact cellular and molecular mechanisms of the effects of SARS-CoV-2 infection on cancer progression, chemo-resistance, metastasis, and recurrence have not been fully understood.

The impact of epithelial-mesenchymal transition (EMT) induced by metabolic processes and intracellular signaling pathways on chemo-resistance, metastasis, and recurrence in solid tumors.

The intricate cellular process, known as the epithelial-mesenchymal transition (EMT), significantly influences solid tumors development. Changes in cell shape, metabolism, and gene expression linked to EMT facilitate tumor cell invasion, metastasis, drug resistance, and recurrence. So, a better understanding of the intricate processes underlying EMT and its role in tumor growth may lead to the development of novel therapeutic approaches for the treatment of solid tumors.

Safety and Immunogenicity of Intranasal Razi Cov Pars as a COVID-19 Booster Vaccine in Adults: Promising Results from a Groundbreaking Clinical Trial.

Protective antibodies in the upper respiratory tract prevent the spread of COVID-19 in the community. Intranasal vaccines could raise the specific secretory IgA and IgG levels. This is a single-center, randomized, double-blind, placebo-controlled clinical trial to evaluate the safety and immunogenicity of Razi Cov Pars (RCP) intranasal recombinant protein subunit COVID-19 vaccine as a booster in adults.

Analysis of immunological and biochemical parameters after booster dose vaccination using protein-based and inactivated virus vaccine for safety.

Introduction: Heterologous vaccines enhance the immune response to new variants and allow flexibility in booster administration when the original vaccine is unavailable. Studies show that heterologous boosters can generate comparable or superior antibody responses compared to homologous boosters. Considering rare side effects is essential in evaluating COVID-19 vaccines, especially those associated with ChAdOx1-S (AstraZeneca) and Ad26.

Microbiome as an endocrine organ and its relationship with eye diseases: Effective factors and new targeted approaches.

Microbiome is an endocrine organ that refers to both the complicated biological system of microbial species that colonize our bodies and their genomes and surroundings. Recent studies confirm the connection between the microbiome and eye diseases, which are involved in the pathogenesis of eye diseases, including age-related macular disorders, diabetic retinopathy, glaucoma, retinitis pigmentosa, dry eye, and uveitis. The aim of this review is to investigate the microbiome in relation to eye health.
