BACKGROUND Serum biomarkers of metabolic syndrome predict abnormal lung function in World Trade Center particulate matter (WTC-PM)-exposed Fire Department of New York (FDNY) rescue workers. In animal models, exposure to ambient PM induces non-alcoholic fatty liver disease (NAFLD), a well-known comorbidity of metabolic syndrome. YKL-40 is an inflammatory biomarker for both liver and lung disease...

We find that institutional ownership in publicly traded companies is associated with more innovation (measured by cite-weighted patents). To explore the mechanism through which this link arises, we build a model that nests the lazy-manager hypothesis with career-concerns, where institutional owners increase managerial incentives to innovate by reducing the career risk of risky projects. The dat...

Interacting with residents, medical students, and other “learners” (the new politically correct, nonperjorative term) affords loads of opportunities. Sure, this responsibility forces providers to maintain a certain level of competency; it reminds us of the fragility of the young ego; it allows us to believe that we are somehow molding the future of medicine. Working with learners also ensures l...

BACKGROUND Kaposi's sarcoma (KS) is associated epidemiologically with HIV infection and a number of countries have reported a dramatic increase in the incidence of KS with the advent of AIDS. Although AIDS is prevalent in Kenya, no studies on the impact of AIDS on the pattern of KS has been carried out. OBJECTIVE To determine any changes in the pattern of KS that might have occurred since the...

The exchange maker-taker pricing scheme affects incentives to take or make markets resulting in narrower bid-ask spreads. This study traces the effect of maker-taker pricing on stock quotations. The analyses consider distributions of quotation sizes, values implied from these sizes, and changes in these sizes and values. The results help inform the current debate on whether tick sizes should be...

In this study, supercritical carbon dioxide (scCO2) extractions of cannabinoids were conducted at four different densities (231, 590, 818, and 911 kg/m3) using ethanol (5% w/v) as a co-solvent. The chemical profiles these analysed via reverse-phase high-performance liquid chromatography (RP-HPLC). It was determined that scCO2, low density (231 kg/m3), produced an extract yield 6.1% w/v. At high...
