Aim:The aims of this review are to assess the anti-viral and targeting strategies using nano materials and the possibility of using Silver nanoparticles for combating the SARS-CoV-2. Background: The novel Coronavirus (SARS-CoV-2) has become a global pandemic and has spread rapidly worldwide. Researchers have successfully identified the molecular structure of the novel coronavirus however significant success has not yet been observed with the therapies currently in clinical trials and exhaustive studies are yet to be carried out in the long road to discovery of a vaccine or a possible cure. Another hurdle associated with the discovery of a cure is the mutation of this virus which may occur at any point in time. Hypothesis: Previous studies have identified a wide number of strains of Coronaviruses with differences in virulent properties. Silver nanoparticles have been used extensively in anti-viral research with promising results in-vitro. However, it has not yet been tested for the same in clinical subjects. It has also been tested on two variants of coronavirus in-vitro with significant data to understand the pathogenesis and which may be implemented in further research possibly in other variants of coronavirus. Another interesting targeting approach would be to test the effect of Silver Nanoparticles on TNF-α as well as Interleukins in SARS-CoV-2 patients. Conclusion: Sufficient evidence is required for its therapeutic potential and it still has to go a long way in SARS-CoV-2 research.

An Alcoholic Liver Disease (ALD) has emerged as the serious health problem globally, with high morbidity and mortality rate. Heavy alcohol consumption resulted in broad spectrum of liver diseases ranging from steatosis (alcoholic fatty liver), alcoholic hepatitis (AH), fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). In this review the detailed patho-physiology of the ALD, role of oxidative stress ALD, the mechanism of action of flavonoids with different models used have been explained. Heavy alcohol consumption leads to severe liver diseases, which is demonstrated by increased blood levels of ALT, AST, and/or lactate dehydrogenase (LDH) and accumulation of lipid in the hepatocytes causing steatosis. There are three mechanisms involved in causing of ALD, those are: (a) acetaldehyde toxicity; (b) oxidative stress or generation of ROS; and lastly (c) provocation of the immune response of hepatocytes causing oxidative stress. This shows that oxidative stress is a major cause for ALD, therefore, defence activities against this stress are most vital in the prevention of ALD. Application of antioxidants especially flavonoids signifies a rational curative strategy to prevent and cure liver diseases involving oxidative stress. Flavonoids inhibit ROS formation by regulating glutathione S-transferase, mitochondrial succinoxidase etc. Since lipid peroxidation is a result of oxidative stress, lipids are protected from oxidative damage using flavonoids. Various flavonoids and their mechanism of action have been discussed in this review, formulation of these flavonoids will be highly beneficial for treatment of ALD.

Huntington disease is an autosomal neurodegenerative disease that is induced by a repeated trinucleotide sequence of a gene that encodes Huntingtin and is characterized by motor, behavioral, and cognitive manifestations. It is a progressive disorder with symptoms worsening over time. The prevalence of this disease is predominant in the United States as well as the UK. The five main progression stages of this disease are Early stage, Early intermediate stage, Late intermediate stages, Early advanced stage, and Advanced stage. The risk factors at the molecular level are CAG is trinucleotide repeat, CAG instability, and genetic modification. The drugs currently used for this disease are useful only in treating the symptoms of the disease but not as useful long-term therapies. Stem cells remedy on the other hand are much more versatile and might prove effective in the treatment of neurodegeneration. Stem cells, which may be employed in Huntington research, are pluripotent stem cells, embryonic stem cells, neural stem cells, adipose stem cells, and mesenchymal stem cells. Each type of cell line has its essential properties for combating this disease. Although extensive investigations have been carried out for this disease, there is no successful therapy as of today. This review provides comprehensive information on novel stem cell therapy research that has been channeled out for the treatment of this genetic neurodegenerative disorder.
