Artemisinin is an anti-inflammatory phytomedicine with broad-spectrum antiviral activity. Artemisinin and its antimalarial properties were discovered by the Chinese scientist Tu Youyu, who became one of the laureates of the 2015 Nobel Prize in Physiology or Medicine for this breakthrough in tropical medicine. It is a commonly used anti-malaria drug. Artemisinin has recently been repurposed as a potential COVID-19 drug. Its documented anti-SARS-CoV-2 activity has been attributed to its ability to inhibit spike-protein mediated and TGF-β-dependent early steps in the infection process as well as its ability to disrupt the post-entry intracellular events of the SARS-CoV-2 infection cycle required for viral replication. In addition, Artemisinin has anti-inflammatory activity and reduces the systemic levels of inflammatory cytokines that contribute to cytokine storm and inflammatory organ injury in high-risk COVID-19 patients. We postulate that Artemisinin may prevent the worsening of the health condition of patients with mild-moderate COVID-19 when administered early in the course of their disease.

Introduction: Multiple myeloma (MM) is an uncontrolled plasma cell proliferation in the bone marrow, leading to immune dysregulation with impaired humoral immune responses. Conversely, cellular-based responses play a vital role in MM patients. However, the extent and duration of cellular-induced protection remain unclear to date.

Background: The unavoidable propagation of the coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has underscored the urgent requirement for efficacious therapeutic agents. The dried fruit of Retz., namely Chebulae Fructus, is widely used for treating bacterial and viral infectious diseases, which was witnessed to perform anti-SARS-CoV-2 activity in recommended Chinese patent medicine.

Introduction And Objective: Elimination irrigation therapy has been proposed as a potential treatment for upper respiratory tract infections, particularly after the COVID-19 pandemic, due to its antiviral properties and mechanical cleansing effects. Additionally, a combination of mineral water with antibiotic therapy has shownto be effective in improving the course clinical infection and positively impact the immune system, potentially enhancing the normal state of microbiota state. The aim of the study is to investigate the influence of elimination-irrigation therapy using a combination of mineral water and ciprofloxacin on the interaction form of individual microbiota species of the upper respiratory tract mucous membrane.

We investigated a novel cancer immunotherapy strategy that effectively suppresses tumor growth in multiple solid tumor models and significantly extends the lifespan of tumor-bearing mice by introducing pathogen antigens into tumors via mRNA-lipid nanoparticles. The pre-existing immunity against the pathogen antigen can significantly enhance the efficacy of this approach. In mice previously immunized with BNT162b2, an mRNA-based COVID-19 vaccine encoding the spike protein of the SARS-CoV-2 virus, intratumoral injections of the same vaccine efficiently tagged the tumor cells with mRNA-expressed spike protein.

Introduction: This study uses the Exploration, Preparation, Implementation, and Sustainment (EPIS) model to retrospectively describe the mail-based overdose education and naloxone distribution (OEND) program developed in collaboration with the Kentucky Department of Corrections (DOC) for use in the HEALing Communities Study in Kentucky (HCS-KY) and details the reach of this innovative delivery model.
Methods: HCS-KY is a community-engaged cluster-randomized trial assessing the effects of implementing evidence-based practices, including OEND, on overdose death reduction across 16 communities highly impacted by the opioid epidemic in Kentucky. The study launch coincided with the COVID-19 pandemic.
