Purpose of the study: To assess Structural and functional abnormalities associated with High fructose diet-induced Metabolic syndrome in wistar albino rats. Materials and Methods: Metabolic syndrome is induced in adult male Wistar albino rats by feeding a combination of High Fructose Diet (55%) and Fructose enriched water (15%) for 75 days and kept as group 2 or HFrD Group. Normal male Wistar albino rats were kept as Normal control. During the entire course of study, weekly weight gain was monitored once a week in both groups. Biochemical investigations such as lipid profile, liver function test, and renal function test was carried out using standard methods. Routine histological studies were done to analyze the microstructural changes. The obtained data were statistically analyzed by students‘t’ tests and the values were considered statistically significant at p<0.05. Results: Chronic administration of a High fructose diet (HFrD) resulted in obesity, abnormal hepatic and renal functions in wistar rats. The gross and microstructural changes were minimal in the pancreas and heart, whereas significant damages were...

Five marine sponges were collected off Carmen, Agusan del Norte, Philippines and taxonomically identified as Axinyssa sp., Plocamionida sp., Forcepia sp., Pachymatisma sp and Placospongia sp. The “non-polar” (EtOAc-MeOH) and “pola”r (EtOH-H2O) extracts of the marine sponges were prepared and subjected to 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, a total antioxidant capacity assay using the phosphor molybdenum method and antimicrobial assay using the paper disc diffusion method. The marine sponge extracts exhibited low antioxidant activity as indicated by both the percent antiradical activity values obtained which ranged from 0.89% to 5.41% and the total antioxidant capacity values expressed as Ascorbic Acid Equivalence (AAE) ranging from 11.99 to 126.67 AAE and Butylated Hydroxytoluene Equivalence (BHTE) with a value range of 6.64 to 148.30 BHTE). The non-polar extracts from all the marine sponges as well as the polar extract from the marine sponge Forcepia sp. showed antibacterial activity against the two bacterial strains, B. subtilis and E. coli. However, the marine sponge extracts no significant antifungal activity against the two fungal...

Senna alata is an effective novel pharmaceutical medicinal plant. The hot extraction method was used to prepare methanol and ethanol extracts of leaves. The extracts were further evaluated to study Antimicrobial potential, phytochemical analysis, FTIR, and Antioxidant activity. The FTIR analysis showed various functional groups that served as secondary metabolites and responsible for antimicrobial activity. The antimicrobial activity of the extract may be due to the presence of secondary metabolites like alkaloids, terpenoids, phenols, saponins, flavonoids, glycosides and tannins. The Senna alata leaves were evaluated for antimicrobial activity against clinically important bacterial strains such as E. coli, B. cereus, B. subtilis, S. aureus, P. aeruginosa, P. fluorescens, and fungi strain namely A. niger by agar well diffusion method. The ethanolic extract of the leaves of Senna alata showed the highest antioxidant activity. S. alata has a great antimicrobial ability which needs to be intensively discussed...

The noble coronavirus SARS-CoV-2 results in a devastating, multisystem disease among which COVID-19 pneumonia creates serious complications and most of COVID-19 related deaths. COVID-19 patients develop a systemic inflammatory response through interleukin (IL) and tumor necrosis factors. In COVID-19 patients, cytokine storm controlling is the key step for treatment because cytokine attacks own body cells instead of fighting with the virus. We reviewed several literatures to summarize the safety and efficacy of LD-RT in COVID-19 patients. Low dose chest radiation may reduce the inflammation in the lungs in severely ill patients. The radiation offset an immune system called AS a cytokine storm. Several randomized/non-randomized, single/multi-centered, open/close clinical trials are underway in U.S, India, Iran and around the globe. Early studies showed LD-RT reduces the inflammatory cytokines, time of hospitalization, duration of ventilation, and a number of deaths. However, some researchers warned for radiation-induced cancer (lung, breast, and esophageal) and cardiovascular diseases. So, further extensive preclinical studies should be conducted to identify the risk-benefit ratio in COVID-19...

Periodontitis is a destructive inflammatory disease of the periodontium induced by specific microorganisms and requires more specific treatment. The traditional mechanical therapy alone is not sufficient for the treatment of moderate to severe periodontitis because of in accessibility in the deep periodontal pocket and depth of penetration of microorganisms into the periodontal connective tissues. Thus to overcome the limitations of mechanical therapy, local drug delivery into the periodontal pocket is recommended. The local drug delivery of chemotherapeutic agents to the periodontal lesion site has the advantage of loading a higher concentration of drug at the target site minimizing the adverse effect of the drug on the other systems of the body. The local drug delivery system having controlled release should be considered as an adjunctive to mechanical debridement for the treatment of periodontal diseases. This article reviews local drug delivery systems containing antimicrobial agents. Further extensive comparative studies are required to optimize the use of novel drugs in the local drug delivery system to manage periodontal...
