MATERIALS AND METHODS: The antioxidant activity was tested by Hydrogen Peroxide [H2O2] assay, Fluorescence recovery after photo-bleaching [FRAP] assay and 2, 2-diphenyl-1- picrylhydrazyl[DPPH] assay. All tests have shown very good results for the ZnO-TiO2 NCs.
RESULTS: In this study, we present a straightforward, ecofriendly alternative for producing non-toxic zinc oxide and titanium oxide nano-composite material. This study could make a valuable contribution and create new opportunities in the market such as biological and pharmaceutical applications.
CONCLUSION: The in vitro tests concluded that the novel nanocomposite containing ZnO-TiO2 and green tea extract has good anti-oxidant properties and it is non-toxic to the biological systems.
MATERIALS AND METHODS: Retrospective cohort study conducted at Department of ENT and Head & Neck Surgery, Saveetha Medical College Hospital, Thandalam, Chennai, Tamil Nadu, India from September 2022 to March 2024. We included patients presenting with vertigo or dizziness, excluding those with non-vestibular dizziness or incomplete medical records. We analysed demographic data, medical history, and clinical findings from patient records. Data analysis was performed. Continuous variables were compared using independent sample t-tests and categorical variables using chi-square tests.
RESULTS: The study included 268 patients, predominantly females (57.8%) and individuals aged 40-50 years (29.9%). Benign Paroxysmal Positional Vertigo (BPPV) was the most common etiological factor (41.0%), followed by orthostatic dysregulation (17.2%) and vestibular peripheral dysfunction (VPD) (16.0%). Clinical presentations and outcomes varied with the underlying etiology. Overall, 91.0% of the patients showed improvement following treatment, with 7.1% achieving full recovery.
CONCLUSION: This study highlights the complexity of vertigo and dizziness, which are influenced by various factors and demographics. This emphasizes the importance of tailored management strategies and a patient-centered, multidisciplinary approach, emphasizing customized treatments to improve patient outcomes.
MATERIALS AND METHODS: Study was conducted in the neonatal intensive care unit (NICU) of Saveetha Medical College Hospital, India, in 2023, between January and June. This study enrolled 100 neonates who underwent hemodynamic monitoring over 48-72 hours. Hemodynamic parameters including heart rate, blood pressure, and PI were systematically recorded. Statistical and Receiver operating characteristic curve analyses were used to assess the relationship between PI and shock.
RESULTS: Neonates experiencing shock exhibited significantly lower PI values than those without (P < 0.05). ROC curve analysis identified a PI threshold of 0.7 for predicting shock, demonstrating a high sensitivity (92.5%) and specificity (94.78%). Additionally, a significant association was observed between PI and serum lactate level (p < 0.05), underscoring the utility of PI as a predictor of shock severity.
CONCLUSION: The study suggests that a PI < 0.7 may serve as an indicator of circulatory shock in neonates, offers good sensitivity and specificity. The PI, along with clinical parameters and serum lactate levels, is a valuable tool for early shock identification in neonatal intensive care. Further research, including multicenter studies, are warranted to validate these findings.
MATERIALS AND METHODS: Observational studies were conducted to explore the capacity of nanoparticles to quorum quench wound pathogens.
RESULTS: A review of observational studies indicated that nanoparticles exhibit significant quorum-quenching capabilities against wound pathogens. Numerous nanoparticles, including silver, gold, and zinc oxide, have been demonstrated to inhibit QS-regulated activities, thereby reducing bacterial virulence and biofilm formation. These results suggest that nanoparticles could serve as potent agents for mitigating bacterial infections and enhancing wound healing.
CONCLUSION: Nanoparticles show considerable potential as quorum-quenching agents, effectively decreasing bacterial virulence and biofilm formation in wound pathogens. These results indicate promising applications of nanoparticles in managing bacterial infections and improving wound healing.
