Getting the Lead Out of Electronics
Background: Carbonic anhydrases (CAs) are physiologically important enzymes which participate in many gastrointestinal processes such as acid and bicarbonate secretion and metabolic pathways including gluconeogenesis and ureagenesis. The genomic data suggests that there are thirteen enzymatically active members of the mammalian CA isozyme family. In the present study, we systematically examined...
متن کاملGetting the lead out.
Gene expression signatures consisting of tens to hundreds of genes have been found to be informative for different biological states. Recently, many computational methods have been proposed for biological interpretation of such signatures. However, there is a lack of methods for identifying cell signaling pathways whose deregulation results in an observed expression signature. We present a stra...
متن کاملGetting the Word Out on Lead
Suppose that cells divide with rate l, die with rate d, become quiescent with rate α, and “wake up” from quiescence with rate β. We will refer to parameters α and β as quiescence parameters. Note that the “amount of quiescence” in the colony correlates positively with α and negatively with β. Let us denote by i the number of cycling cells and by j the number of quiescent cells. The system’s sta...
متن کامل"Getting the lead out" in Hartford, Connecticut: a multifaceted lead-poisoning awareness campaign.
As part of a citywide effort to increase lead poisoning awareness within the city of Hartford, Connecticut, the Hartford Health Department implemented a multifaceted public health campaign involving several novel elements and partnerships, including the use of municipal sanitation trucks to disseminate lead-poisoning prevention messages throughout the city. To evaluate campaign reach and effect...
متن کاملGetting Out of Control
While driving along a desert highway, we can easily predict the consequences of turning the wheel and changing lanes. However, in heavy traffic this is not the case. Traffic dynamics is complex and the response to any individual change depends on how the other drivers accommodate it [1]. This type of cooperative dynamics in complex systems makes controlling them a scientific and technological c...
