1. Capillaries were isolated from the brains of 1- to 45-day-old rats in order to study the development of metabolic and transport aspects of the blood-brain barrier. 2. The hydroxyproline content of capillary hydrolysates increased nearly threefold between 5 and 45 days of age. This finding is consistent with histological studies showing thickening of capillary basement membrane during development. 3. The activities of L-DOPA decarboxylase and monoamine oxidase were greatest in capillaries from 10-day-old rat brain. Thus, the metabolic blood-brain barrier for amine precursors is present during early development. 4. Capillaries from all ages were able to metabolize glucose, beta-hydroxybutyrate and palmitate. The rate of glucose oxidation more than doubled between 21 and 30 days of age but subsequently decreased. In contrast, beta-hydroxybutyrate and palmitate oxidation increased throughout development. These data suggest a sparing effect by alternate fuels on glucose metabolism. 5. Capillary glucose uptake was similar at 10 and 30 days of age and activity of the ouabain-sensitive K+ pump (measured using 86Rb+) was relatively constant at all ages. In contrast, Na+-dependent neutral amino acid transport was not present until after 21 days of age. Since this transport system may be responsible for the active efflux of neutral amino acids from brain to blood...

Depleting oil reserves and growing environmental concerns have necessitated the development of sustainable processes to fuels and chemicals. Here we have developed a general metabolic platform in E. coli to biosynthesize carboxylic acids. By engineering selectivity of 2-ketoacid decarboxylases and screening for promiscuous aldehyde dehydrogenases, synthetic pathways were constructed to produce both C5 and C6 acids. In particular, the production of isovaleric acid reached 32 g/L (0.22 g/g glucose yield), which is 58% of the theoretical yield. Furthermore, we have developed solid base catalysts to efficiently ketonize the bio-derived carboxylic acids such as isovaleric acid and isocaproic acid into high volume industrial ketones: methyl isobutyl ketone (MIBK, yield 84%), diisobutyl ketone (DIBK, yield 66%) and methyl isoamyl ketone (MIAK, yield 81%). This hybrid “Bio-Catalytic conversion” approach provides a general strategy to manufacture aliphatic ketones, and represents an alternate route to expanding the repertoire of renewable chemicals.

This paper analyzes short-run interfuel substitution between fossil fuels in West European power generation. The problem is studied within a restricted translog cost model, which is estimated by pooling time-series data across eight countries in West Europe. The empirical results indicate that interfuel substitution in existing power plants is substantial, especially that between oil and gas. This is consistent with the notion that short-run fuel substitution primarily occurs in multi-fuel fired plants, by switching load between different single-fuel fired plants, or by some conversions of electric plants to be able to burn alternate fuels as well.; Financial support from Vattenfall, the Kempe Foundations and SNS Energy.

Access to energy, especially modern sources, is a key to any development initiative. Based on cross-section data from a 2004 survey of some 2,300 households in rural Bangladesh, this paper studies the welfare impacts of household energy use, including that of modern energy, and estimates the household minimum energy requirement that could be used as a basis for an energy poverty line. The paper finds that although the use of both traditional (biomass energy burned in conventional stoves) and modern (electricity and kerosene) sources improves household consumption and income, the return on modern sources is 20 to 25 times higher than that on traditional sources. In addition, after comparing alternate measures of the energy poverty line, the paper finds that some 58 percent of rural households in Bangladesh are energy poor, compared with 45 percent that are income poor. The findings suggest that growth in electrification and adoption of efficient cooking stoves for biomass use can lower energy poverty in a climate-friendly way by reducing carbon dioxide emissions. Reducing energy poverty helps reduce income poverty as well.

This paper applies an econometric analysis to estimate the average and distribution benefits of rural electrification using rich household survey data from India. The results support that rural electrification helps to reduce time allocated to fuelwood collection by household members and increases time allocated to studying by boys and girls. Rural electrification also increases the labor supply of men and women, schooling of boys and girls, and household per capita income and expenditure. Electrification also helps reduce poverty. But the larger share of benefits accrues to wealthier rural households, with poorer ones having more limited use of electricity. The analysis also shows that restricted supply of electricity, due to frequent power outages, negatively affects both household electricity connection and its consumption, thereby reducing the expected benefits of rural electrification.

This is a guideline for World Bank task team leaders (TTLs) entrusted with the design and execution of assessments to determine disaster impacts as well as post-disaster needs for recovery, reconstruction, and disaster risk reduction or management. Assessments estimate, first, the short-term government interventions required to initiate recovery and second, the financial requirements to achieve overall post-disaster recovery, reconstruction, and disaster risk management or reduction. The end product of the assessment is a comprehensive program of recovery, reconstruction, and risk management that will guide all actions in a developing country following a disaster. The damage and loss assessment (DaLA) methodology uses objective, quantitative information on the value of destroyed assets and temporary production losses to estimate, first, government interventions for the short term and second, post-disaster financing needs. The DaLA method ensures that the affected government, the United Nations and other international and domestic agencies jointly develop properly estimated and prioritized financial requirements and an accompanying formula that identifies all possible financial sources and modalities. In addition...

Export restraints by the Russian Federation on natural gas and timber have been the source of major controversy between the European Union and the Russian Federation. The analysis of this paper suggests that the export restraints in natural gas very substantially benefit Russia. On the other hand, in raw timber the analysis suggests that a substantial reduction of Russian export taxes would increase Russian welfare. The paper explains that Gazprom has failed to invest adequately, resulting in little development of new gas supplies. The result has been progressively increasing use by Gazprom of Central Asian gas supplies, at progressively higher prices for Russia. The increased prices of gas for Russian consumers have shown that it is crucial for Russia to allow new entrants and to introduce competition in the Russian domestic market. Without export restraints, however, competition among multiple gas suppliers from Russia would erode or eliminate the monopoly profits of the Russian Federation on gas exports. Thus...

Approved for public release; distribution is unlimited.; At the beginning of the 21st century, the United States Marine Corps (USMC) took a leading role in the war on terror. The traditionally amphibious force deployed massive amounts of troops and supplies in two major land wars of occupation. Now, as the USMC winds down its participation in the conflicts, it must seek to return to its roots as a primarily amphibious force without the benefits of a land-based operation. Tomorrows battles will likely begin from the littorals in and around the coastal regions of the developing world. The Marine Corps must prepare itself to operate without the benefit of readily available fossil fuels and supplies shipped in by trucks or home-based supply lines. As demonstrated in the current conflicts, the threats of IEDs and the expenses of obtaining fossils fuels make it imperative that the Marine Expeditionary Brigade (MEB) of the future must be able to bring its supplies with them or have them delivered by readily available and close-by alternate means. This research will evaluate the current landing doctrine of a notional MEB and its associated ship-to-shore connectors. It will analyze potential changes in doctrine with the goal of reducing energy footprint while maintaining mission effectiveness.

An investigation is reported of the relationships between nutrient status of foliar and litter materials from Australian forests and the three components of flammability, namely, ignitability, sustainability, and combustibility. The Limiting OKygen Index (LOI) method was chosen as an index of ignitability and sustainability, and combustibility has been measured by Thermogravimetric Analysis . (TGA) and Derivative Thermogravimetric Analysis (DTG). Results derived from LOI and TGA are seen to be more reproducible and reliable than other methods commonly used in m~asuring forest fuel flammability. The first study examines the general relationship between a number of chemic, .. l attributes and the flammability of the leaves of 47 species. A significant correlation between nutrient status and flammability was found, foliar calcium in particular, appearing to have most effect on flammability. Because of this, the major study involves a comprehensive evaluation of relationships between flammability and nutrient concentrations in green foliage, freshly fallen leaves, and litter decomposing on the forest floor. Thirteen species have been used, drawn from the vegetational gradient, dry sclerophyll forest to rainforest. Ignitahility and sustainability of forest fuels are greater in materials with lower nutrient concentrations...

Part 1 of the paper reviews recent trends in fossil fuel use and associated externalities. It also argues that the recent run-up in international oil prices reflects growing concerns about supply constraints associated with declining spare capacity in OPEC, refining bottlenecks, and geopolitical uncertainties rather than growing incremental use of oil by China and India. Part 2 compares two business as usual scenarios with a set of alternate scenarios based on policy interventions on the demand for or supply of energy and different assumptions about rigidities in domestic and international energy markets. The results suggest that energy externalities are likely to worsen significantly if there is no shift in China's and India's energy strategies. High energy demand from China and India could constrain some developing countries' growth through higher prices on international energy markets, but for others the "growth retarding" effects of higher energy prices are partially or fully offset by the "growth stimulating" effects of the larger markets in China and India. Given that there are many inefficiencies in the energy system in both China and India...

O crescimento populacional e a industrialização das economias emergentes demandam um constante aumento na produção global de energia. Além disso, as preocupações ambientais devido à necessidade de diminuição das emissões de CO2 no marco do protocolo de Kyoto, têm levado ao surgimento de propostas de fontes de energias renováveis, sendo uma alternativa aos combustíveis fósseis. Biodiesel e bioetanol são as alternativas mais pesquisadas, no entanto elas ainda apresentam desvantagens que impedem seu uso massivo. Recentemente, tem surgido a proposta da produção de hidrocarbonetos com número de átomos de carbono maior ou igual a C4 (e.g. buteno, n-butanol, hidrocarbonetos combustíveis na faixa de C4-C10) a partir de etanol, via catálise heterogênea. Nesse sentido, já foram testados diversos catalisadores na reação de etanol, como: óxidos e hidróxidos metálicos, carbonatos, fosfatos, sulfatos, silicatos e aluminatos. Os resultados mais promissores foram obtidos com os catalisadores preparados a base de hidroxiapatita não estequiométrica. Nesse contexto, o objetivo deste trabalho foi pesquisar novos catalisadores que apresentassem as características das apatitas, visando a produção de uma mistura de hidrocarbonetos combustíveis (oxigenados e não oxigenados) condensáveis...

InI3 catalyzes the reaction of branched alkanes with methanol to produce heavier and more highly branched alkanes, which are more valuable fuels. The reaction of 2,3-dimethylbutane with methanol in the presence of InI3 at 180−200 °C affords the maximally branched C7 alkane, 2,2,3-trimethylbutane (triptane). With the addition of catalytic amounts of adamantane the selectivity of this transformation can be increased up to 60%. The lighter branched alkanes isobutane and isopentane also react with methanol to generate triptane, while 2-methylpentane is converted into 2,3-dimethylpentane and other more highly branched species. Observations implicate a chain mechanism in which InI3 activates branched alkanes to produce tertiary carbocations which are in equilibrium with olefins. The latter react with a methylating species generated from methanol and InI3 to give the next-higher carbocation, which accepts a hydride from the starting alkane to form the homologated alkane and regenerate the original carbocation. Adamantane functions as a hydride transfer agent and thus helps to minimize competing side reactions, such as isomerization and cracking, that are detrimental to selectivity.

The Muoio lab studies the interplay between lipid whole body energy balance,

mitochondrial function and insulin action in skeletal muscle. Data from our lab suggests that lipid-induced insulin resistance in skeletal muscle may stem from excessive incomplete oxidation of fatty acids, which occurs when high rates of β-­oxidation exceed TCA cycle flux (Koves et al., 2005; Koves et al., 2008). Most notably, we have shown that mice with a genetically engineered decrease in mitochondrial uptake and oxidation of fatty acids are protected against diet-­induced insulin resistance (Koves et al., 2008). This

suggests that an excessive and/or inappropriate metabolic burden on muscle

mitochondria provokes insulin resistance. Our working model predicts that: 1) high rates of incomplete β-oxidation reflect a state of ”mitochondrial stress,” and 2) that energy-overloaded mitochondria generate a yet unidentified signal that mediates insulin

resistance. One possibility is that this putative mitochondrial-derived signal stems from redox imbalance and disruptions in redox sensitive signaling cascades. Therefore, we are interested in identifying molecules that link redox balance, mitochondrial function and insulin action in skeletal muscle. The work described herein identifies thioredoxin-interacting protein (TXNIP) as an attractive candidate that regulates both glucose homeostasis and mitochondrial fuel selection.

TXNIP is a redox sensitive...

It has been long known that many types of cancers have high metabolic requirements and use reprogrammed metabolism to support cellular activities. The first identified metabolic alteration in cancer cells was elevated glucose uptake, glycolysis activity and lactate production even in the presence of oxygen. This metabolic program, termed aerobic glycolysis or the Warburg effect, provides cells with energy as well as biosynthetic substrates to sustain cell survival and rapid cell proliferation. Cancer metabolism is closely linked to genetic mutations and oncogenic signaling pathways, such as PI3K/Akt, cMyc and HIF pathways. These oncogenic signals can direct metabolic reprogramming while changes in metabolic status can regulate activities of these signaling pathways in turn. In addition to glucose, later studies also found utilization of alternate nutrients in cancer cells, including glutamine and lipids. Glutamine is the second major metabolic fuel and can be converted to various substrates to support cell bioenergetics needs and biosynthetic reactions. Usage of metabolic fuels in cancer cells, however, is variable. While certain cancers display addiction to one type of nutrient, others are capable of using multiple nutrients.

The unique metabolic features of cancer cells raise the possibility of targeting metabolism as a novel therapeutic approach for cancer treatment. Using pharmacological inhibitors...
