Noninvasive diagnostic biomarkers, genomic profiling, and advanced microscopic imaging in the early detection and characterization of Naegleria fowleri infections leading to primary amebic meningoencephalitis (PAM).

This review delves into the strategies for early detection and characterization of Naegleria fowleri infections leading to primary amoebic meningoencephalitis (PAM). The study provides an in-depth analysis of current diagnostic approaches, including cerebrospinal fluid analysis, brain tissue examination, immunostaining techniques, and culture methods, elucidating their strengths and limitations. It explores the geographical distribution of N. fowleri, with a focus on regions near the equator, and environmental factors contributing to its prevalence. The review emphasizes the crucial role of early detection in PAM management, discussing the benefits of timely identification in treatment, personalized care, and prevention strategies. Genomic profiling techniques, such as conventional PCR, nested PCR, multiplex PCR, and real-time PCR, are thoroughly examined as essential tools for accurate and prompt diagnosis. Additionally, the study explores advanced microscopic imaging techniques to characterize N. fowleri's morphology and behavior at different infection stages, enhancing our understanding of its life cycle and pathogenic mechanisms. In conclusion, this review underscores the potential of these strategies to improve our ability to detect, understand, and combat N. fowleri infections, ultimately leading to better patient outcomes and enhanced public health protection.

Synthesis, characterization, and applications of iron oxide nanoparticles.

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 µg/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.

The Prevalence of Blood Borne Diseases in Blood Donors of Peshawar, Khyber Pakhtunkhwa, Pakistan.

BACKGROUND: The goal of the study was to investigate the burden of transfusion- transmitted infections (TTIs) hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), syphilis, and malarial parasite (MP) in ABO Blood Groups and Rh Type System among voluntarily blood donors in Khyber Pakhtunkhwa (KPK), Pakistan. It is a retrospective single center cross sectional study. This study was conducted from June 2020 to September 2021 (16 months) at the frontier foundation thalassemia center Peshawar KPK. Donors were physically healthy and fit for donation. Donors with physical disabilities and/or having co-morbid conditions were excluded from the report. METHODS: All the samples were screened for anti-HIV, anti-HCV, HBsAg, Syphilis, and Malarial Parasite via ELISA kit and Immune Chromatographic Technique (ICT), respectively. A total of 6311 blood donations were evaluated. The majority of the donations (92%) were from (VNRBD) voluntary non-remunerated blood donation, while only 8% came from replacement donors. RESULTS: Amongst 6311 blood donations, 1.50 % (n = 95) were infected at least with one pathogen, HBV positive cases were 0.855 % (n = 54), HCV positive cases were 0.316% (n = 20), syphilis positive were 0.30% (n = 19) and MP positive cases were only 0.031% (n = 2). HBV, HCV, syphilis and malaria infections rates were found to be low as compared to the previous data published, while no case was reported for HIV. The study also revealed the distribution pattern of the aforementioned pathogens in blood groups and the Rh type system of the reactive samples. CONCLUSION: The lower reported in our study indicates the awareness among the people of Peshawar about TTIs and their precautions. The prevalence rate that we are reporting is less than previously published articles in the same domain.
