Cold atmospheric plasma (CAP) is a novel technology with boundless significance that can be used in the medical sector that offers noninvasive in-vivo applications without damaging the living tissues. CAPs can be obtained by curtailing the concentration of high-energetic electrons per phase and by freezing molecules/atoms (devoid of charge) in plasma utilizing gas circulation and atmospheric air, which includes a variety of charged and neutral reactive entities, UV rays, electric currents, and fields, etc. that have an influence on cellular material in a multitude of diverse manners. Reactive oxygen species (ROS) and reactive nitrogen species (RNS), produced by the plasma, essentially cause biological and therapeutically advantageous plasma effects. CAP plasma has several important biological functions, including the deactivation of pathogens, induction of tissue restoration and cell propagation, the annihilation of cells by triggering apoptosis, etc. Several fundamental concepts are defined, even if the precise process of the effect of plasma on biomolecules is still not properly identified. Depending on the biological synthesis of RNS and ROS in reactions to plasma emissions, the present review described several aspects of plasma therapy in neuroscience, particularly in anti-glioblastoma, neuro-differentiation, and neuroprotection and also the various applications of CAP in medical fields where it is used in the therapy of SARS-CoV-2, cancer therapy, and chronic and acute wounds. Furthermore, the proliferation in stem cells, dental medicines, dermatology, and a brief insight into CAP devices and their risk factors was highlighted.
In the Hubei region of China, a pneumonia outbreak occurred in December 2019, which was confirmed to be caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). It quickly became known as Coronavirus Disease 2019 or simply COVID-19, a pandemic that continues to devastate countries across the world. Through this COVID-19 pandemic, pharmacists across the globe have continued to offer direct patient care and provided frontline service to society. However, while the frontline staff is heralded, they are relegated to the background and overlooked most of the time. The most reachable healthcare providers are pharmacists because they can provide direct medical services despite tight regulations and restrictions related to the pandemic. During this pandemic, the involvement of pharmacists to handle COVID-19 and its complications proved to be crucial in alleviating the burden on the already strained healthcare system. They have provided very important services such as distributing medications to patients, encouraging adherence to medications for better control of chronic diseases, consulting on minor illnesses, clarifying myths regarding COVID-19, and contributing to COVID-19 screening. The treatment or management of COVID-19 was based on initial findings but is now being updated several times based on viral mutation, different studies across the globe, etc. This review focuses on recent clinical updates and tools that would help pharmacists with a more systematic approach to properly handling COVID-19 and its complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
