Blood Lead Level (BLL) in the Adult Population of Jodhpur: A Pilot Study

Lead interferes with a variety of body processes and is toxic to many organs and tissues including the heart, bones, intestines, kidneys, and reproductive and nervous systems. Routes of exposure to lead include contaminated air, water, soil, food, and consumer products. The possibility of lead exposure in humans is therefore of great significance from health point of view. Occupational exposure is a common known cause of lead poisoning in adults but current status of adults exposed otherwise is not known. School teachers representing wide local population were selected and asked to furnish information regarding possible lead exposure. Blood lead level (BLL) was estimated using anodic stripping voltammetry. The mean BLL was 6.89 ± 9.5 μg/dl (<3.5–>65 μg/dl) in representative adult population. Out of the total 16 % were found to be having BLL >10 μg/dl which has significantly decreased from leaded gasoline era. Those with increased BLL (>10 μg/dl) were found to have common determinants like usage of old metallic pipes for plumbing, water consumption without any purification system, usage of cosmetics and Ayurvedic/herbal medicines.     

Association of Resistin with Insulin Resistance and Factors of Metabolic Syndrome in North Indians

Metabolic syndrome (MetS) is a cluster of interrelated common clinical disorders. The role of resistin in insulin sensitivity and MetS is controversial till date. So, the aim of the present study was to investigate the relationship of plasma resistin levels with markers of the MetS in Indian subjects. In a case control study, total 528 subjects were selected for the study. 265 (194 male and 71 female) were cases (with MetS) and 263 (164 male and 99 female) were controls (without MetS). Required anthropometric measurements and calculations were carried out accordingly. All the Biochemical estimations were carried out according to standard protocol. Resistin level was measured by the standard protocol (By ELISA i.e. enzyme linked immunosorbent assay) as illustrated in the kit. Insulin level was also measured by the standard protocol as illustrated in the kit and insulin resistance was calculated by the standard procedures. Plasma resistin levels were significantly higher in cases compared with controls (male = 13.05 ± 4.31 vs. 7.04 ± 2.09 ng/ml; p ≤ 0.001 and female = 13.53 ± 4.14 vs. 7.42 ± 2.30 ng/ml; p ≤ 0.001). Plasma resistin levels were well correlated with waist circumference, glucose, triglycerides, waist/hip ratio, systolic and diastolic blood pressure, high density lipoprotein, total cholesterol, serum low density lipoprotein, serum very low density lipoprotein, insulin and insulin resistance. Plasma resistin levels were elevated in presence of the MetS and were associated with increased metabolic risk factors.     

Giving the “Viewser” a Voice? Situating the Individual in Relation to Personalization,Narrowcasting, and Public Service Broadcasting

This article undertakes a critical comparison of contemporary personalization practices on Web platforms such as YouTube and Facebook with long-established practices of narrowcasting. Though such platforms appear to adhere to goals of universality similarly adhered to by public service broadcasting (PSB), the implementation of personalization on these platforms proves problematic to their discursive positioning as free “public” services. Furthermore, though public service broadcasters have embraced personalization in the name of pluralism, critics suggest that the narrowcasting inherent in personalization exists in tension to PSB's enduring commitments. Finally, the article argues that system-initiated personalization negates the “consumer sovereignty” that narrowcasting has traditionally mobilized.
