Eco-friendly synthesis of PbTiO3 nanoparticles and PbTiO3/carbon quantum dots binary nano-hybrids for enhanced photocatalytic performance under visible light

PbTiO3 nanoparticles, carbon quantum dots CQDs and their composite (i.e. PbTiO3/CQDs) were prepared and studied using XRD, FT-IR, VSM, TEM, BET, PL, FESEM, UV�Vis, and EDX. Designing highly-effective PbTiO3/CQDs binary nano-hybrids include several fascinating properties of visible light, biocompatibility, eco-friendly response and good durability. Various composites containing different amounts of CQDs were prepared, and the effects of catalysts on enhancing the photocatalytic activity of PbTiO3 nanoparticles in the resulting binary nano-hybrid have been investigated. Test experiments indicated that PbTiO3 nanoparticles could remove only 53 of Rh B, while PbTiO3/5CQDs binary nano-hybrids reached a removal maximum of 100. Further the removal of different dyes using the PbTiO3/CQDs binary nano-hybrids has been evaluated and the removal mechanism has also been discussed. © 2018 Elsevier B.V

The Association between Macronutrients Intake with High sensitivity C-Reactive Protein (hs-CRP) in Elderly of Sabzevar Nursing Homes (A Cross-Sectional Study)

Background and Objectives: High-Sensitivity C-reactive protein (hs-CRP) is the most reliable means of diagnosing and controlling hidden inflammation and infection in the body. poor nutritional status in older adults with increased serum levels of CRP, followed by systemic inflammation is linked. It appears that diet has an significant effect on chronic inflammation affecting the progression of the disease. This study aimed to examine the association between macronutrients intake with serum High sensitivity C-reactive protein in elderly located in nursing homes in Sabzevar. Materials & Methods: This cross-sectional analytical study included 105 nursing home residents from Sabzevar city, stratified sampling method was performed. Anthropometric indexes, BMI and WHR were measuremed according standard methods. Nutrientional intake per person was collected and determined by using the N4 software. Blood samples were collected for measurement of serum hs-CRP. Data were analyzed by using SPSS software descriptive statistics and regression. Results: In the present study, a significant positive correlation between total fat and cholesterol intake and a significant inverse correlation between fiber intake and serum high sensitivity C- reactive protein was observed. Among Anthropometric indexes, hs-CRP has a statistically significant relationship with BMI. Conclusion: According to results of this study, diets high in fiber, low in fat, low cholesterol should be the first level of prevention in this age group and it can reduce inflammation remarkably

The Effect Of Curcumin Supplementation On Lipid Profiles In Hemodialysis Patients

Abstract. The aim of this study was to determine the effect of curcumin on systemic inflammation andserum lipid profiles in hemodialysis patients. The aim of this study was to determine the effect of curcumin on systemic inflammation and serum lipid profiles in hemodialysis patients. Then, an experimental group received 80 mg of curcumin for 2 months and the control group received placebo. Before and after intervention, after 12 hours of fasting blood cc5, blood samples were taken from patients for triglyceride, cholesterol, HDL-C and LDL-C parameters. Data were then entered into SPSS 16 software and analyzed by Kolmogorov-Smirnov, Chi-square, Fisher test and T-test. According to the results of the analyzes, the results of the assumptions under study indicated that the supplementation of curcumin reduced serum LDL-C concentrations (P <0.05) and increased serum HDL-C (P = 0.003) in hemodialysis patients. Serum cholesterol and serum triglyceride in patients without hemodialysis are equal to (P> 0.05). The results of this study showed that curcumin supplement can be effective in preventing heart disease and can be used as a complementary therapy.Keywords: Curcumin, Systemic inflammation, Hemodialysis, Serum lipid profile
