Objective: The green synthesis method for nanoparticles is getting more attention globally, due to its lesser cost, non-hazardous, and eco-friendly nature. The novelty of the present work is to investigate the anti-bacterial and degradation activity of the green synthesized Iron Oxide NPs. Methods: In this study, the Iron Oxide NPs were synthesized through a green synthesis route from leaves of Ficus Palmata. UV-Vis confirmed Iron Oxide NP's peaks between (230-290 nm), while Fourier transforms infrared spectroscopy analysis showed that several groups were involved in reduction and stabilization. Results: Results indicated that the highest photo thermal activity was shown in light and it was almost 4 folds greater than the control. Similarly, Iron Oxide NPs showed excellent antimicrobial potential against bacterial species "Salmonella typhi" "Xanthomonas Oryzae" and "Lactobacillus" at low concentrations (150 mu g/mL). Hemolytic assay results showed that the toxicity was lesser than 5% at both dark and light conditions. Moreover, we also evaluated the photo-catalytic potential of Iron Oxide NPs against methylene orange. Results indicated that almost complete degradation was noted after 90 min in the presence of continuous light. All tests were performed in triplicates. All the data was subjected to P-test (P < 0.5) using Excel and graph pad (V.5.0). Conclusion: Iron Oxide NPs holds a promising future and could be used in treating diseases, and microbial pathogenesis and also could be used as a vector in drug delivery. Moreover, they can also eradicate persistent dyes and could be used as an alternative to remediate pollutants from the environment.

Background: Increased resistance of microorganisms to commonly prescribed antibiotics has emerged as a significant hurdle in contemporary medical practice. The World Health Organization (WHO) has declared antibiotic resistance as a " major threat to public health.". In the present study, bacterial isolates were selected based on high antibiotic and heavy metal tolerance from a water sample taken from hospital sewage.Methods: Antibiotic-resistant bacteria were isolated through the disk diffusion method. Gram staining was done for morphological identification. For molecular identification, the 16s rDNA PCR amplification was done with universal primers. Results: The strain BC1 was found resistant to ampicillin (10μg/ml), and cefixime (5μg/ml). While, susceptible to kanamycin (30μg/ml), azithromycin (15μg/ml) and intermediate in response to amoxicillin (30μg/ml). The strain BC2 was resistant to ampicillin (10μg/ml), cefixime (5μg/ml) and kanamycin (30μg/ml). While, Susceptible to amoxicillin (30μg/ml), and intermediate in response to azithromycin (15μg/ml). The strains were also found resistant to heavy metals.Conclusion: The recent investigation on bacterial strains from hospital effluent found interesting candidates for understanding the AMR bacteria and developing novel active biomolecules to combat the antibiotics problem. The isolated strains could be a source of novel resistant genes however; a comprehensive molecular analysis is needed for advanced studies.

Aim: Head and Neck squamous cell carcinoma (HNSCC) is the second most prevalent cancer in Pakistan. Methods: Gene expression data from TCGA and GETx for normal genes to analyze Differentially Expressed Genes (DEGs). Data was further investigated using the Enrichr tool to perform Gene Ontology (GO). Results: Our analysis identified most significantly differentially expressed genes and explored their established cellular functions as well as their potential involvement in tumor development. We found that the highly expressed Keratin family and S100A9 genes. The under-expressed genes KRT4 and KRT13 provide instructions for the production of keratin proteins. Conclusion: Our study suggests that factors such as poor oral hygiene and smokeless tobacco can result in oral stress and cellular damage and cause cancer.
