British Journal ofSurgery; 75.’1166-1168 A total of 52 jaundiced elderly patients who had malignant obstruction of the distal common bile duct and who required palliative biliary decompression w...

The development of adaptive resistance of Salmonella enterica serovar Enteritidis ATCC 4931 biofilms following exposure to benzalkonium chloride (BC) either continuously (1 microg ml(-1)) or intermittently (10 microg ml(-1) for 10 min daily) was examined. Biofilms adapted to BC over a 144-h period could survive a normally lethal BC challenge (500 microg ml(-1) for 10 min) and then regrow, as de...

Replacement of the native fermentation pathway in Escherichia coli B with a homo-ethanol pathway from Zymomonas mobilis (pdc and adhB genes) resulted in a 30 to 50% increase in growth rate and glycolytic flux during the anaerobic fermentation of xylose. Gene array analysis was used as a tool to investigate differences in expression levels for the 30 genes involved in xylose catabolism in the pa...

The human genitourinary tract is a common anatomical niche for polymicrobial infection and a leading site for the development of bacteremia and sepsis. Most uncomplicated, community-acquired urinary tract infections (UTI) are caused by Escherichia coli, while another bacterium, Proteus mirabilis, is more often associated with complicated UTI. Here, we report that uropathogenic E. coli and P. mi...

Cellular metabolism is a series of tightly linked oxidations and reductions that must be balanced. Recycling of intracellular electron carriers during fermentation often requires substrate conversion to undesired products, while respiration demands constant addition of electron acceptors. The use of electrode-based electron acceptors to balance biotransformations may overcome these constraints....

Under limited commitment that prevents agents from pledging their future nonfinancial wealth, agents with incorrect beliefs always survive by holding on their nonfinancial wealth. Friedman (1953)’s market selection hypothesis suggests that their financial wealth trends towards zero in the long run. However, in this paper, I construct an example in dynamic general equilibrium in which over-optim...

cucumber mosaic virus (cmv) is one of widely-spread viruses of plants with the broadest host range encompassing over 1200 species. one major limiting factor for detection of the virus is unavailability of the virus-specific antibodies especially in developing countries. recombinant dna technology facilitates antibody preparation without requiring special equipment. in this study, coat protein (...

bubbles in asset prices have fascinated researchers in finance. identify asset bubbles, by circumstances, on the stock market has been a growing number of research theoretical and empirical. on a theoretical level, it was assumed that the price dynamics reflect irrational behavior of economic agents and, therefore, should be excluded from a deal with the truly rational economic agents burmeiste...
