In this report, MgSrAl10O17:xDy³ nanophosphors were fabricated by combustion method for different concentrations (x = 0, 0.0005, 0.001, 0.005, 0.01 and 0.02) of Dysprosium (Dy). The synthesised nanophosphors were characterised by XRD, SEM, TEM, FTIR, PL, and TL. The XRD (X-ray diffraction) showed crystalline hexagonal structure with preferred orientation of (107) plane. SEM (Scanning electron microscope) result shows the formation of nanosheets in an irregular shape. TEM (transmission electron microscope) study revealed the nanoparticles an average diameter of 30 nm. TL (Thermo-luminance) properties included TL glow curves and TL response for different concentrations of Dy after exposure to 700 Gy gamma rays. LiMgBO3 shows the major TL glow peak at 100oC. TL intensity was found to increase with an increase in the dopant Dy concentration and was found to show the best result for x = 0.02. Further, PL (Photoluminescence) characterisation of MgSrAl10O17:0.02 Dy3+ phosphor exhibits two main emission peaks at 484 and 575 nm due to Dy3+ ion, when excited with 350 nm wavelength. So, emission of the Dy3+ luminescence is close to the white region, and hence MgSrAl10O17:xDy3+ phosphor can be a good candidate in solid-state lighting for white light emission. In kinetic parameters: activation energy (E) and order of kinetics (b), are calculated using the Chen's Peak Shape method. [ABSTRACT FROM AUTHOR]

In this report, LiMgBO3:Dy3+ nanophosphors have been fabricated by conventional solid state reaction at different concentrations of Dysporsium (Dy).

Background: Urinary tract infection (UTI) is the most common infection experienced by humans after respiratory and gastro-intestinal infections, and also the most common cause of nosocomial infections for patients admitted to hospitals indeed UTIs are the most frequent bacterial infection in women. Aim: The aim was to determine the prevalence of UTI and to identify factors associated with an increased risk of UTI among nursing students. Subjects and Methods: The cross-sectional study involved 177 unmarried nursing students aged 18-30 years studying in the SRMSIMS, Nursing College Bareilly. A structured questionnaire was used, and study subjects were asked regarding the symptoms of UTI in the previous 3 months. Chi-square test and Univariate Logistic Regression was used to analyze the data. Results: The overall prevalence of UTI was found to be 19.8% (35/177). Rural background, inadequate water intake, and unsatisfactory toilet habits were found to be strong predictors of UTI. Conclusions: There is an urgent need to sensitize the nursing students regarding the growing need of the issue so that they themselves become aware in addition to raising the awareness of other high-risk groups.

In the present study, single phase nickel based disulphide (NiS 2 ) and diselenide (NiSe 2 ) nanostructures were prepared hydrothermally in a short time span (4 h) under subcritical temperature (160 °C). The nanostructures grow in cubic crystal phases. Average crystallite sizes and intrinsic microstrains were determined using Williamson-Hall (W-H) plot analysis. Hollow NiS 2 nanospheres and bipyramidal NiSe 2 nanostructures are reported that are suitable for surface related applications. Thermal gravimetric analysis (TGA) indicated high stability of the nanostructures at elevated temperatures. Optical studies indicated visible light activeness of the nanostructures exhibiting sharp band edges. The nanostructures are mesoporous in nature with NiS 2 and NiSe 2 having respectively a large specific surface area of 310 m 2 /g and 177 m 2 /g. A primarily work done to determine the electrochemical nature of the nanostructures showed the materials are pseudo-capacitive in nature with specific capacitances of 1022 F/g and 480 F/g respectively for NiS 2 and NiSe 2 . The photo-catalytic activity of the nanostructures was explored against a colourless pollutant; phenol. The nanostructures degraded most of the phenol (>90 %) under visible light illumination and the reusability experiments performed determined industrial value of the photocatalysts., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 Published by Elsevier Ltd.)

Wogonin (5,7-dihydroxy-8-methoxy flavone), an active component isolated from the root of Scutellaria baicalensis Georgi. Neurotoxic effects of γ irradiation have been established in humans and animals. The current study was designed to evaluate whether wogonin could restrain γ irradiation-induced neurotoxicity in rats and to explore the underlying mechanisms. Rats were divided into five groups, 10 rats each. Group 1 was orally administered distilled water and served as control. Group 2 received an oral daily dose of wogonin (30 mg/kg). Rats in group 3 were exposed to a whole-body single dose of γ-irradiation. Animals in group 4 received an oral daily dose of wogonin (30 mg/kg) for 15 days then exposed to a whole-body single dose of γ-irradiation. In group 5, rats were exposed to a whole-body single dose of γ-irradiation then were orally administered a daily dose of wogonin (30 mg/kg) for 15 days. There were significant increases in malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and Interleukin 6 (IL-6) levels and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) mRNA and protein expression. Whereas significant decreases in reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) level as well as nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) mRNA and protein expression in the irradiated group when compared with the relevant control. The cerebral cortex of irradiated rats showed vacuolization and nuclear pyknosis in the neuronal cells and focal gliosis. Wogonin administration pre- or post-irradiation significantly ameliorated all these previous effects. Wogonin had antioxidant and anti-inflammatory effects and ameliorated the histopathological changes in the brain., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier B.V.

Background: Until date, the importance of maternal health care services in reducing maternal mortality and morbidity has received a significant recognition. Most of the maternal deaths can be prevented if women have access to basic antenatal, natal and postnatal care. However, uptake of maternal health care services is far from universal even in settings where they are extensively available., Aim: The aim of this study is to assess the pattern and identify underlying factors on maternal health care utilization in rural areas of Bareilly., Subjects and Methods: This was a cross-sectional study was conducted during June-December 2011. Six villages were selected by convenience out of 99 villages in Bhojipura Block of Bareilly district, Uttar Pradesh to cover maximum number of women. All currently married women aged between 15 and 49 years who had delivered a child within last 1 year were interviewed by house-to-house survey and comprised the study unit. Their socioeconomic and demographic characteristics, reproductive history and knowledge of specific obstetric complications were taken. The information was gathered on various aspects of maternal-care utilization. In analyzing data, both bivariate and multivariate analyses were employed, using the Microsoft Excel and SPSS for Windows, Version 15.0 (SPSS Inc., Chicago, Illinois,USA)., Results: Most (88.6%; 343/387) of pregnancies had registration for antenatal care (ANC). Majority (69.7%; 239/343) of them were registered between 16 and 24 weeks. Only 28.5% (110/343) of women received ANC from a private doctor. Maternal health care service utilization from health personnel was significantly associated with age at marriage ≥18 years, family size ≤3, birth order ≤2, nuclear family and higher socio-economic status. Most of the pregnancy related complications were found among women aged >30 years, with birth order ≥3, having birth interval <24 months, among Muslims, working mothers and among those belonging to joint family. Mother's education and husband's occupation were found to be strong predictors for the utilization of maternal health care using the logistic regression., Conclusion: Utilization of maternal health care services is high. However this can be improved by community based education program.
