Wounds are structural and functional disruptions of skin that occur because of trauma, surgery, acute illness, or chronic disease conditions. Chronic wounds are caused by a breakdown in the finely coordinated cascade of events that occurs during healing. Wound healing is a long process that split into at least three continuous and overlapping processes: an inflammatory response, a proliferative phase, and finally the tissue remodeling. Therefore, these processes are extensively studied to develop novel therapeutics in order to achieve maximum recovery with minimum scarring. Several growth hormones and cytokines secreted at the site of lesions tightly regulates the healing processes. The traditional approach for wound management has been represented by topical treatments. Metal nanoparticles (e.g., silver, gold and zinc) are increasingly being employed in dermatology due to their favorable effects on healing, as well as in treating and preventing secondary bacterial infections. In the current review, a brief introduction on traditional would healing approach is provided, followed by focus on the potential of wound dressing therapeutic techniques functionalized with Ag-NPs.

Purpose of Study: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), deals with Coronavirus Disease 2019 (COVID-19) has instantly spread worldwide, leading to an episode of intense irresistible pneumonia. The COVID-19 pandemic has created a phenomenal change in educational teaching-learning framework globally. Other than financial and social effects, there is a difficulty in adopting new online education systems by stakeholders of academic institutions. Methodology: The review presented here is based on the platinum open access literature focusing on the adoption of the online education system during the current pandemic situation. This compilation of the findings is based on a systematic review published by the scholars of the relevant field of research targeted to opportunities and challenges in adopting ICT (Information and Communication Technology) and online teaching-learning pedagogy. Main Findings: Specifically, school students need to deal with various sorts of ecological, electronic, and mental battles because of the COVID-19 pandemic. The whole education system from elementary to tertiary level has been imploded during the lockdown time of the COVID-19 in India and worldwide. The New Education Policy (NEP) 2020 has been delivered by the recently renamed Ministry of Education. The approach has given another face to the Online Education System in India. Applications of this study: The finding of the current investigation is a portrayal of opportunities and challenges in receiving the online teaching-learning education system by the public and private educational institutions. It will help in the planning and development of strategies to handle the challenges and opportunities of e-learning during the current global epidemic. Novelty of the study: The authors endeavored to address the web-based learning and teaching in the school training system in the midst of the COVID-19 pandemic. The capacity of offered resources in academic organization effectively changed conventional education into online schooling with the help of virtual classes and other urgent online gadgets in this reliably moving instructive scene.
