Melamine is a nitrogenous organic compound containing high amounts of nitrogen, which is interpreted as high protein in various standard protein measuring tests, therefore added to foods to boost the protein content. Illegal addition of melamine has been in practice by food manufacturers, which leads to toxicity and stone formation in kidneys of individuals consuming melamine-contaminated milk products. A focused and thorough structured search of bibliographic databases for peer-reviewed researches reported in the literature was carried out with a focused attention on melamine contamination, associated health risks, and the role of gut microbiota. The overall outcomes of the research and review articles pertaining to searched keywords along with analysis of the interventions have been described employing a deductive qualitative content analysis approach. Current review focuses on the various health risks associated with consumption of melamine-contaminated foods and the need to develop better and effective methods for its testing. Moreover, the importance of gut microbiota in mediating toxicity due to melamine has also been discussed as there is a link between toxicity and activities of gut microbiota.

Background: Recent pandemic of coronavirus disease caused by a novel coronavirus SARS-CoV-2 in humans is the third outbreak by this family of viruses leading to an acute respiratory infection which has been a major cause of morbidity and mortality worldwide.The virus belongs to the genus, Betacoronavirus which has been recently reported to have significant similarity (>89%) to a severe acute respiratory syndrome (SARS)-related member of the Sarbecoviruses. Current researches are not sufficient to understand the etiological and immunopathobiological parameters related to COVID-19 so as to have a therapeutic solution to the problem. Methods: A structured search of bibliographic databases for peer-reviewed research literature has been carried out using focused review questions and inclusion/exclusion criteria. Further Standard tools were implied in order to appraise the quality of retrieved papers. The characteristic outcomes of screened research and review articles along with analysis of the interventions and findings of included studies using a conceptual framework have been described employing a deductive qualitative content analysis methodology. Results: This review systematically summarizes the immune-pathobiological characteristics, diagnosis, potential therapeutic options for the treatment and prevention of COVID-19 based on the current published literature and evidence. The current review has covered 125 peer-reviewed articles, majority of which are from high-income technically developed countries providing the most recent updates about the current understanding of the COVID-19 bringing all the significant findings and related researches together at a single platform. In addition, possible therapeutic interventions, treatment strategies and vaccine development initiatives to manage COVID-19 have been proposed. Conclusions: It is anticipated that this review would certainly assist the public in general and scientific community in particular to recognize and effectively deal with COVID-19, providing a reference guide for futuristic studies.

In the processes of molecular docking and simulation studies; the computational techniques have a vast and significant role in drug discovery process. The rigid view in the binding of both target and ligand is the basis of modeling strategy process. More evolution to such processes with the time has lead in revealing the path of understanding the dynamic nature of binding processes. In this chapter we have focused on molecular docking along with dynamic studies in reference to biological processes.

Phytochemicals are the natural biomolecules produced by plants via primary or secondary metabolism, which have been known to have many potential health benefits to human beings. Flavonoids or phytoestrogens constitute a major group of such phytochemicals widely available in variety of vegetables, fruits, herbs, tea, and so forth, implicated in a variety of bio‐pharmacological and biochemical activities against diseases including bacterial, viral, cancer, inflammatory, and autoimmune disorders. More recently, these natural biomolecules have been shown to have effective antiviral properties via therapeutically active ingredients within them, acting at different stages of infection. Current review emphasizes upon the role of these flavonoids in physiological functions, prevention and treatment of viral diseases. More so the review focuses specifically upon the antiviral effects exhibited by these natural biomolecules against RNA viruses including coronaviruses. Furthermore, the article would certainly provide a lead to the scientific community for the effective therapeutic antiviral use of flavonoids using potential cost‐effective tools for improvement of the pharmacokinetics, bioavailability, and biodistribution of such compounds for the concrete action along with the promotion of human health.
