ABSTRACT
In the current pandemic, COVID-19 patients with predisposing factors are at an increased risk of mucormycosis, an uncommon angioinvasive infection that is caused by fungi with Mucor genus which is mainly found in plants and soil. Mucormycosis development in COVID-19 patient is related to various factors, such as diabetes, immunocompromise and neutropenia. Excessive use of glucocorticoids for the treatment of critically ill COVID-19 patients also leads to opportunistic infections, such as pulmonary aspergillosis. COVID-19 patients with mucormycosis have a very high mortality rate. This review describes the pathogenesis and various treatment approaches for mucormycosis in COVID-19 patients, including medicinal plants, conventional therapies, adjunct and combination therapies.
ABSTRACT
ABSTRACT@#The oral microbiome comprises several hundreds of bacterial species that contribute to periodontitis, the most complex polymicrobial inflammatory disorder. Porphyromonas gingivalis is a prominent periodontitis pathogen that produces gingipains as a major virulent factor. Gingipain facilitates P. gingivalis survival, pathogenicity, and growth. Several genes were identified to have a role in the regulating of P. gingivalis pathogenesis. Studies suggest that gingipains inhibition is key for the successful treatment of periodontitis. As of now, several gingipain inhibitors have been developed, some exhibit high inhibition activity against gingipains. However, most inhibitors offer unknown toxicity and undesirable side effects. Hence, the development of highly potent and safe gingipain inhibitor is a major concern for periodontitis treatment. The present review highlights the connectivity between P. gingivalis, virulent factors, and its gene, periodontitis, and gingipain inhibitors. Development of gingipains inhibitors would not only treat periodontitis but would also assist in the treatment of other associated systemic diseases, for example: rheumatoid arthritis, cardiovascular diseases, diabetes, and Alzheimer's disease.

The objective of present study was to explore the hepatoprotective and antioxidant profile of Citrullus colocynthis fruits. Hepatoprotective profile of methanolic extract of Citrullus colocynthis fruits [MECCF] was investigated on rats, which were made hepatotoxic using paracetamol. The antioxidant profile of MECCF was evaluated by conducting Catalase, Super oxide Dismutase, Lipid Peroxidation and Diphenyl Picryl Hydrazyl tests. During hepatoprotective investigation, the Paracetamol treated group II showed significant increase in total bilirubin [TB], serum glutamate oxaloacetate transaminase [SGOT], serum glutamate pyruvate transaminase [SGPT] and alkaline phosphatase [ALP] level. The results so obtained showed that pretreatment of rats with MECCF 300mg/kg p.o. decreases the elevated TB, SGOT, SGPT and ALP serum levels. Also, MECCF inhibitory profile was found comparable with toxicant group [Paracetamol 2g/kg, p.o.]. The present study concludes that MECCF fruit possess significant hepatoprotective and antioxidant activity
