Markers of Inflammation, Coagulation, and Renal Function Are Elevated in Adults with HIV Infection

Abstract: Background. Human immunodeficiency virus (HIV) replication and immune activation may increase inflammation and coagulation biomarkers. Limited data exist comparing such biomarkers in persons with and without HIV infection. Methods. For persons 45‐76 years of age, levels of high-sensitivity C-reactive protein (hsCRP), interleukin (IL)‐6, D-dimer, and cystatin C were compared in 494 HIV-infected individuals in the Strategies for Management of Anti-Retroviral Therapy (SMART) study and 5386 participants in the Multi-Ethnic Study of Atherosclerosis (MESA) study. For persons 33‐44 years of age, hsCRP and IL-6 levels were compared in 287 participants in the SMART study and 3231 participants in the Coronary Artery Development in Young Adults (CARDIA) study. Results. hsCRP and IL-6 levels were 55% ( ) and 62% ( ) higher among HIV-infected participants P ! .001 P ! .001 than among CARDIA study participants. Compared with levels noted in MESA study participants, hsCRP, IL-6, D-dimer, and cystatin C levels were 50%, 152%, 94%, and 27% higher, respectively ( , for each), among P ! .001 HIV-infected participants. HIV-infected participants receiving antiretroviral therapy who had HIV RNA levels 400 copies/mL had levels higher (by 21% to 60%) ( ) than those in the general population, for all P ! .001 biomarkers. Conclusions. hsCRP, IL-6, D-dimer, and cystatin C levels are elevated in persons with HIV infection and remain so even after HIV RNA levels are suppressed with antiretroviral therapy. Additional research is needed on the pathophysiology of HIV-induced activation of inflammatory and coagulation pathways, to guide potential interventions.

Beyond the Glass Ceiling: Does Gender Matter?

Abstract: A large literature documents that women are different from men in their choices and preferences, but little is known about gender differences in the boardroom. If women must be like men to break the glass ceiling, we might expect gender differences to disappear among directors. Using a large survey of directors, we show that female and male directors differ systematically in their core values and risk attitudes, but in ways that differ from gender differences in the general population. These results are robust to controlling for differences in observable characteristics. Consistent with findings for the population, female directors are more benevolent and universally concerned but less power oriented than male directors. However, in contrast to findings for the population, they are less tradition and security oriented than their male counterparts. They are also more risk loving than male directors. Thus, having a woman on the board need not lead to more risk-averse decision making. This paper was accepted by Brad Barber, Teck Ho, and Terrance Odean, special issue editors.

Nanofluid-based direct absorption solar collector

Abstract: Solar energy is one of the best sources of renewable energy with minimal environmental impact. Direct absorption solar collectors have been proposed for a variety of applications such as water heating; however the efficiency of these collectors is limited by the absorption properties of the working fluid, which is very poor for typical fluids used in solar collectors. It has been shown that mixing nanoparticles in a liquid (nanofluid) has a dramatic effect on the liquid thermophysical properties such as thermal conductivity. Nanoparticles also offer the potential of improving the radiative properties of liquids, leading to an increase in the efficiency of direct absorption solar collectors. Here we report on the experimental results on solar collectors based on nanofluids made from a variety of nanoparticles (carbon nanotubes, graphite, and silver). We demonstrate efficiency improvements of up to 5% in solar thermal collectors by utilizing nanofluids as the absorption mechanism. In addition the experiment...
