Boosting the injured brain with supplemental energy fuels

Lactate Fuels the Neonatal Brain

brain tissue. (2) Metabolic recovery pathways are fundamentally altered when lactate or hydroxybutyrate replaces glucose as the primary oxidative substrate. The implications of this study reach beyond enhancing our understanding of how the neonatal brain functions. While the observations that lactate can serve as a substrate for the neonatal brain confirms existing knowledge, the facts that it ...

Energy from Fossil Fuels.

Lactate fuels the human brain during exercise.

The human brain releases a small amount of lactate at rest, and even an increase in arterial blood lactate during anesthesia does not provoke a net cerebral lactate uptake. However, during cerebral activation associated with exercise involving a marked increase in plasma lactate, the brain takes up lactate in proportion to the arterial concentration. Cerebral lactate uptake, together with gluco...

Comparative Energy and Exergy Analysis for the Utilization of Alternative Fuels in the Cement Kiln

The cement industry is one of the most energy and carbon-intensive industries. The energy and carbon reduction is an important issue in this industry. The present work considers the use of alternative fuels in the cement kilns. The amounts of excess air, the location of fuel and air entrance, as well as the amount of produced gas stacks, are the main design and operational variables in the kiln...

Prospects for conversion of solar energy into chemical fuels: the concept of a solar fuels industry.

There is, at present, no solar fuels industry anywhere in the world despite the well-publicized needs to replace our depleting stock of fossil fuels with renewable energy sources. Many obstacles have to be overcome in order to store sunlight in the form of chemical potential, and there are severe barriers to surmount in order to produce energy on a massive scale, at a modest price and in a conv...
