OBJECTIVE To isolate and characterize the bioactive secondary metabolites from Aspergillus ochraceus (A. ochraceus) MP2 fungi. METHODS The anti bacterial activity of marine sponge derived fungi A. ochraceus MP2 was thoroughly investigated against antagonistic human pathogens. The optimum inhibitory concentration of the fungi in the elite solvent was also determined. The promising extracts tha...

Most OECD countries experience high unemployment rates and declining growth in higher educational attainment. An often suggested government policy is therefore to allocate resources towards formal schooling for adults. However, returns on such investments are uncertain and the foregone earnings are potentially large. We use Swedish population register data from 1982 to 2011 to estimate average ...

BACKGROUND The reservoir of pathogenic ciprofloxacin-resistant Escherichia coli remains unknown. METHODS We conducted a prospective cohort study of 80 healthy twins and their mothers to determine the frequency of excretion of ciprofloxacin-resistant, potentially pathogenic E. coli. Stool specimens were cultured selectively for ciprofloxacin-resistant gram-negative bacteria. Isolates were cate...

Entrepreneurship is largely ignored or treated in a highly simplified way in endogenous growth theory. Still, it is now widely recognized that the supply of entrepreneurial talent is likely to be important for economic growth, innovation and job creation. This study consists of an indepth examination of how the supply of productive entrepreneurship is likely to be affected by the kind of tax an...

BACKGROUND Previous studies have shown that pretreatment with normobaric hyperoxia has cardioprotective effect in isolated rat heart. The present study was designed to test the hypothesis that pretreatment normobaric hyperoxia could induce delayed cardioprotection effect in an in vivo regional heart ischemia. MATERIALS AND METHODS Experiment 1: Rats were exposed to normobaric normoxia or to n...

INTRODUCTION The combination of hardness, scratch resistance and flexibility is a highly desired feature in many coating applications. A potential route to achieve this aim is via the introduction of a nanoparticle filler into the polymer resin. The great interest for using nanoparticles to reinforce polymers emerged in the late 1980s when a research group from Toyota reported their findings re...

On the Consequences of the US Withdrawal from the Kyoto/Bonn Protocol* The US decision not to ratify the Kyoto Protocol and the recent outcomes of the Bonn and Marrakech Conferences of the Parties has important implications for both the effectiveness and the efficiency of future climate policies. Among these implications, those related with technical change and with the functioning of the inter...

Compacted and water saturated bentonite will be used as an engineered barrier in deep geological repositories for radioactive waste in many countries. Due to the high dose rate of ionizing radiation outside the canisters holding the nuclear waste, radiolysis of the interlayer and pore water in the compacted bentonite is unavoidable. Upon reaction with the oxidizing and reducing species formed b...

Fiscal considerations may shift governmental priorities away from environmental concerns: Finance ministers face strong demand for public expenditures such as infrastructure investments but they are constrained by international tax competition. We develop a multi-region model of tax competition and resource extraction to assess the fiscal incentive of imposing a tax on carbon rather than on cap...

Aulak, Kulwant S., Thomas Koeck, John W. Crabb, and Dennis J. Stuehr. Dynamics of protein nitration in cells and mitochondria. Am J Physiol Heart Circ Physiol 286: H30–H38, 2004; 10.1152/ ajpheart.00743.2003.—Nitric oxide is a precursor of reactive nitrating species such as peroxynitrite and nitrogen dioxide that modify proteins to generate 3-nitrotyrosine. Many diseases are associated with inc...
