In standard models of economic choice, consumers select their favorite commodity bundles from among those that they can afford. Nobody asks the chosen commodities how they feel about the consumers who choose them. Students, however, are familiar with real-life decision problems in which the outcomes depend crucially on the preferences of both the choosers and the chosen. The so-called “marriage...
The ubiquitous Aeromonas hydrophila is responsible for several pathological conditions in fish and human. Like most gram negative bacteria, its virulence relies on outer membrane lipopolysachharide (LPS). The Leloir pathway enzyme UDP-galactose 4-epimerase (GalE), plays an important role in the LPS biosynthesis, and therefore is a potential drug target. We have earlier carried out extensive bio...
We are interested in a well-known problem in Computer Science and Economics, the Stable Marriage Problem (SM). Considering two communities in which each member has some preferences on the potential partners, the goal is to make pairs taking into account their preferences. This abstract problem has many applications. From a multiagent approach, the seminal Gale-Shapley algorithm [2] solves the S...
Many strains of a wide variety of bacterial species have been studied for their amino acid decarboxylase activity (Gale, 1946). However, to our knowledge the lactobacilli have not been examined. It has been shown in our laboratory that oral lactobacilli may be classified into three types according to their ability to attack certain carbohydrates, intensity of acid production from glucose, and b...
The nucleotide sequences of the Lactobacillus helveticus lactose utilization genes were determined, and these genes were located and oriented relative to one another. The lacLM genes (encoding the beta-galactosidase protein) were in a divergent orientation compared to lacR (regulatory gene) and lacS (lactose transporter). Downstream from lacM was an open reading frame (galE) encoding a UDP-gala...
Lipopolysaccharide (LPS) is a key antigen in immunity to leptospirosis. Its biosynthesis requires enzymes for the biosynthesis and polymerization of nucleotide sugars and the transport through and attachment to the bacterial membrane. The genes encoding these functions are commonly clustered into loci; for Leptospira borgpetersenii serovar Hardjo subtype Hardjobovis, this locus, named rfb, span...
[1] A kilometers‐thick sedimentary sequence in Gale Crater exhibits stratigraphic changes in lithology that are consistent with transitions in aqueous and climatic conditions purported to be global in scale. The sequence is divided into two formations, where the Lower formation exhibits a net transition in mineralogy from clay/sulfate to sulfate/oxide assemblages and is separated from the overl...
