Herein, we report the ultrasonic-assisted precipitation technique for the fabrication of Cu-doped TiO2 nanoparticles. The prepared sample showed high crystallinity, purity and nanoparticles like structure with the diameter in the range of 10–22 nm. The bandgap for Cu-doped TiO2 nanoparticles was estimated to be 2.91 eV using Tauc plot, which is considerable for improving the light-harvesting capacity. Further, the prepared Cu-doped TiO2 was used as photocatalyst for the eradication of ofloxacin (OFX), an antibiotic from an aqueous phase under visible illuminations. About 72% degradation of OFX (10 mg/L, pH 7) was achieved with Cu-doped TiO2 nanoparticles after 180 min of visible illumination. The probable photocatalytic mechanism for the decomposition of OFX has been proposed based on reactive species trapping study. Moreover, the antibiotic efficiency of OFX was investigated against Escherichia coli and it was observed that its antimicrobial activity was significantly diminished after the photocatalytic decomposition of the OFX solution with synthesized nanoparticles. © 2021 The Society of Powder Technology Japan

Background: Thyroid dysfunction (TD) is considered a common cause of secondary hypertension (HT). Therefore, correcting TD may help in quicker and sustained achievement of desired blood pressure goals. However, there is a paucity of literature from India which estimates the relationship of HT with TD. Objectives: The objective of the study was to estimate the prevalence of TD with HT and to identify associated factors among Indian population. Materials and Methods: The survey data of the National Family Health Survey 4 (NFHS-4), conducted in India during 2015-2016, were analyzed using R statistical software for estimating the relationship between a history of HT and TD among women (N = 687246) aged 15-49 years and men (N = 108492) aged 15-54 years. Descriptive statistical tests and logistic regression were applied. Results: Among the persons suffering from the TD, the prevalence of HT was 32.8%, which was significantly higher than the prevalence of HT (21.9%) in euthyroid individuals. Further, the prevalence of TD was higher among hypertensive adults (2.5%) compared to nonhypertensive (1.5%). Conclusions: The study reported a higher prevalence of TD among the hypertensive persons and higher prevalence of HT among cases of TD. Therefore, screening for thyroid disorders should be routinely considered for better management of HT. © 2023 Indian Journal of Public Health.
