In this research work, the antioxidant and metabolomic profiling of seven selected medicinally important herbs including Rauvolfia serpentina, Terminalia arjuna, Coriandrum sativum, Elettaria cardamom, Piper nigrum, Allium sativum, and Crataegus oxyacantha was performed. The in vivo cardioprotective potential of these medicinal plants was evaluated against surgically induced oxidative stress through left anterior descending coronary artery ligation (LADCA) in dogs. The antioxidant profiling of these plants was done through DPPH and DNA protection assay. The C. oxyacantha and T. arjuna showed maximum antioxidant potential, while the E. cardamom showed poor antioxidative strength even at its high concentration. Different concentrations of extracts of the said plants exhibited the protection of plasmid DNA against H2O2 damage as compared to the plasmid DNA merely treated with H2O2. The metabolomic profiling through LC-MS analysis of these antioxidants revealed the presence of active secondary metabolites responsible for their antioxidant potential. During in vivo analysis, blood samples of all treatment groups were drawn at different time intervals to analyze the cardiac and hemodynamic parameters. The results depicted that the group pretreated with HC4 significantly sustained the level of CK-MB, SGOT, and LDH as well as hemodynamic parameters near to normal. The histopathological examination also confirmed the cardioprotective potential of HC4. Thus, the HC4 being safe and inexpensive cardioprotective herbal combination could be considered as an alternate of synthetic drugs.

The COVID-19 outbreak is creating severe impressions on all facets of the global community. Despite strong measures worldwide to try and re-achieve normalcy, the ability of SARS-CoV-2 to survive sturdy ecological settings may contribute to its rapid spread. Scientists from different aspects of life are working together to develop effective treatment strategies against SARS-CoV-2. Apart from using clinical devices for patient recovery, the key focus is on developing antiviral drugs and vaccines. Given the physical size of the SARS-CoV-2 pathogen and with the vaccine delivery platform currently undergoing clinical trials, the link between nanotechnology is clear, and previous antiviral research using nanomaterials confirms this link. Nanotechnology based products can effectively suppress various pathogens, including viruses, regardless of drug resistance, biological structure, or physiology. Thus, nanotechnology is opening up new dimensions for developing new strategies for diagnosing, preventing, treating COVID-19 and other viral ailments. This article describes the application of nanotechnology against the COVID-19 virus in terms of therapeutic purposes and vaccine development through the invention of nanomaterial based substances such as sanitizers (handwashing agents and surface disinfectants), Nanotechnology

The economic importance of mastitis and antibiotic resistance is dictating to search non-antibiotic alternatives for the therapy. Trisodium citrate (TSC) being buffer system of the glandular tissue and, vitamin C (Vit. C), zinc and copper being important ingredients required for functioning of immune system fancy chances for a suitable alternative mastitis therapy. The current study was planned to evaluate therapeutic efficacy and cost effectiveness of these ingredients in subclinical mastitis. For this purpose, 40 sub-clinically mastitis cows were randomly divided into 2 equal groups. Group T1 was treated orally with TSC, Vit. C, ZnSo4 and CuSo4, while group T2 was treated with standard antibiotic therapy. Milk pH significantly (P<0.05) differed between the two treatments till day 7th post-initiation of treatment when T1 restored the pH values within normal range earlier than T2. A non-significant (P>0.05) difference was observed in milk pH, fat, lactose, proteins, TS, SNFs, somatic cell counts and restoration of milk yield between the two treatments indicting comparable efficacy. A statistically significant (P<0.05) difference was observed in serum Cu and Zn levels indicating that the supplementation of Cu and Zn led to higher serum values in animals of T1. The use of non-antibiotic oral formulations as mastitis therapy resulted in a net profit of Rs. 457/animal/day. The oral non-antibiotic antibacterial formulation is a therapeutically and economically suitable alternative to rational antibiotic-based therapy to treat subclinical mastitis in dairy cows.
