Health beliefs and folk models of diabetes in British Bangladeshis: a qualitative study

Objective: To explore the experience of diabetes in British Bangladeshis, since successful management of diabetes requires attention not just to observable behaviour but to the underlying attitudes and belief systems which drive that behaviour.

Synthesis and biological evaluation of superactive agonists of growth hormone-releasing hormone.

Analogs of the 29 amino acid sequence of human growth hormone-releasing hormone (hGH-RH) with agmatine (Agm) in position 29, desaminotyrosine (Dat) in position 1, norleucine (Nle) in position 27, and L-alpha-aminobutyric acid (Abu) in position 15 have been synthesized, and their biological activity was evaluated. Some peptides contained one or two residues of ornithine (Orn) instead of Lys in positions 12 and 21 and additional replacements in positions 8 and 28. All analogs were found to be more potent than hGH-RH-(1-29)-NH2 in the superfused rat pituitary cell system. In tests in vivo in rats after subcutaneous administration, the analogs JI-22, [Dat1, Orn12,21, Abu15, Nle27, Agm29]hGH-RH-(1-29); JI-34, [Dat1, Orn12,21,Abu15,Nle27, Asp28, Agm29]hGH-RH-(1-29); JI-36, [Dat1, Thr8, Orn12,21, Abu15,Nle27,Asp28,Agm29]hGH-RH-(1-29); and JI-38, [Dat1,Gln8, Orn12,21,Abu15,Nle27,Asp28,Agm29]hGH-RH-(1 -29) displayed a potency 44.6,80.9,95.8, and 71.4 times greater, respectively, than that of hGH-RH-(1-29)-NH2 at 15 min and 217.1, 89.7, 87.9, and 116.8 times greater at 30 min. After intravenous administration, JI-22, JI-36, and JI-38 were 3.2-3.8 times more potent than hGH-RH-(1-29)-NH2 at 5 min and 6.1-8.5 times more active at 15 min. All analogs were found to have higher binding affinities for GH-RH receptors on rat pituitary cells than hGH-RH-(1-29)-NH2. Because of high activity and greater stability, these analogs could be considered for therapy of patients with growth hormone deficiency.

Solar Photovoltaic Energy Project Development on Brownfields: Leveraging Policy Incentives and Project Financing Mechanisms

This study evaluates the practice of redeveloping Brownfields with solar photovoltaic renewable energy technology. Utilizing renewable energy as a strategy to reuse contaminated or potentially contaminated property is a relatively new convention. While the benefits of redeveloping Brownfields are well established, ongoing challenges and limited literature on the subject complicate the practice. Challenges, opportunities, and benefits related to renewable energy development on Brownfields are identified and analyzed. Strategic leveraging of federal, state, local, and utility incentives for renewable energy and Brownfield revitalization, and gap finance tools is explored and evaluated. A comparison of three photovoltaic Brownfield projects is analyzed for critical success and failure factors, and lessons learned. A recommendation of best practices is made based on findings and results.

Intimate partner violence in older women in Spain: prevalence, health consequences, and service utilization

The purpose of this study is to estimate the prevalence of lifetime intimate partner violence (IPV) in older women and to analyze its effect on women's health and Healthcare Services utilization. Women aged 55 years and over (1,676) randomly sampled from Primary Healthcare Services around Spain were included. Lifetime IPV prevalence, types, and duration were calculated. Descriptive and multivariate procedures using logistic and multiple lineal regression models were used. Of the women studied, 29.4% experienced IPV with an average duration of 21 years. Regardless of the type of IPV experienced, abused women showed significantly poorer health and higher healthcare services utilization compared to women who had never been abused. The high prevalence detected long standing duration, negative health impact, and high healthcare services utilization, calling attention to a need for increased efforts aimed at addressing IPV in older women.

Fate and Transport of Naproxen in a Sandy Aquifer Material: Saturated Column Studies and Model Evaluation

Naproxen-C14H14O3 is a nonsteroidal anti-inflammatory drug which has been found at detectable concentrations in wastewater, surface water, and groundwater. Naproxen is relatively hydrophilic and is in anionic form at pH between 6 and 8. In this study, column experiments were performed using an unconsolidated aquifer material from an area near Barcelona (Spain) to assess transport and reaction mechanisms of Naproxen in the aquifer matrix under different pore water fluxes. Results were evaluated using HYDRUS-1D, which was used to estimate transport parameters. Batch sorption isotherms for Naproxen conformed with the linear model with a sorption coefficient of 0.42 (cm3 g−1), suggesting a low sorption affinity. Naproxen breakthrough curves (BTCs) measured in soil columns under steady-state, saturated water flow conditions displayed similar behavior, with no apparent hysteresis in sorption or dependence of retardation (R, 3.85-4.24) on pore water velocities. Soil sorption did not show any significant decrease for increasing flow rates, as observed from Naproxen recovery in the effluent. Sorption parameters estimated by the model suggest that Naproxen has a low sorption affinity to aquifer matrix. Most sorption of Naproxen occurred on the instantaneous sorption sites, with the kinetic sorption sites representing only about 10 to 40% of total sorption.
