Anti-filarial IgG4 in men and women living in Brugia malayi-endemic areas.

Abstract: To assess whether antifilarial IgG4 can be used to study various epidemiological facets of filarial infections, we studied this isotype in 238 individuals resident in areas endemic for brugian filariasis, focusing on the differences between men and women. In the study area, the prevalence of microfilariae was 6.7% and the prevalence of antifilarial IgG4 was 49.2%. All microfilariae carriers were positive for antifilarial IgG4, whereas a proportion of the endemic normals (94/208) and clephantiasis patients (7/14) had IgG4 antibodies to filarial antigens. Data were analysed as a function of gender in distinct clinical groups and stratified for age. The prevalence of microfilariae was higher in males in all age groups, as reflected in significantly higher antifilarial IgG4 antibody levels compared to females. The prevalence of IgG4 increased to reach a plateau at the age of 30 years in both males and females. These results indicate that antifilarial IgG4 antibodies can reflect the differences in the extent of infection in males and females as measured by microfilarial counts, and that this parameter can be used for epidemiological assessments of filarial infection.

Analysis of structural properties of X-ray diffraction for composite copper-activated carbon by modified Williamson-Hall and size-strain plotting methods

Abstract: Structural properties of composite carbon with metal Cu (CCu) were analysis from the X-ray Diffraction (XRD) data by modified Williamson-Hall (W-H) and size-strain plotting methods The effect of temperature shows influenced to increasing the resistance from 373% at room temperature to 664% for 600°C By using the modified equation of Williamson-Hall, we found that the crystallite size about 4078 nm Modified Williamson-Hall (W-H) plotting and Gaussian distribution shows good correlation and accuration for determining the crystallite size from the XRD data in this study

The effect of shade on chlorophyll and anthocyanin content of upland red rice

Abstract: Upland red rice (Oryza sativa) is a staple food and contains anthocyanin, which can act as antioxidants, plays an important role both for the plant itself and for human health. Levels of antioxidants in rice can be affected by the availability of light. The results showed that the difference of shade, cultivar, and interaction both significantly affect the content of chlorophyll a, chlorophyll b and total chlorophyll. The results also showed that shade could increase chlorophyll in all cultivars tested. The highest levels of chlorophyll a were present in the moderate shade level (n2), then decreased at the shelter level (n3) and increased again at high levels (n4). While on chlorophyll content b, it appears that shade increased chlorophyll b in all cultivars tested and this increase was linear to the increase of shade. The shade treatment may increase the anthocyanin content and the increase depending on the type of cultivar. Increased levels of anthocyanin highest due to shade occurred on Jangkobembe cultivar. The original level of anthocyanin on Jangkobembe cultivar averaged 0.096 mg g-1 increased to 2.487 mg g-1 or increased 26 fold. It is concluded that the shade had a significant effect on the chlorophyll and anthocyanin content.
