We cloned a complete cDNA encoding rye seed chitinase-c, designated RSC-c, by rapid amplification of cDNA end and PCR procedures. The cDNA of RSC-c consists of 1,O18 nucleotides and includes an open reading frame encoding a po]ypeptide of 266 amino acid residues. A recombinant RSC-c was produced by expression in Escherichia coli Origami(DE3) and purified. rRSC-c had almost the same chitinase ac...

The vast majority of cases of gram-negative meningitis in neonates are caused by K1-encapsulated Escherichia coli. The role of the K1 capsule in the pathogenesis of E. coli meningitis was examined with an in vivo model of experimental hematogenous E. coli K1 meningitis and an in vitro model of the blood-brain barrier. Bacteremia was induced in neonatal rats with the E. coli K1 strain C5 (O18:K1...

Regional Economic Growth and Human Capital: The Role of Overeducation The paper analyses the link between human capital and regional economic growth in the European Union. Using various indicators of human capital calculated from census microdata, we conclude that the recent economic performance of European regions is associated with an increase in overeducation. In fact, measures of educationa...

Low-energy dipole (LED) excitations in $^{18}\mathrm{O}$ were investigated using a combination of the variation after $K$ projection framework antisymmetrized molecular dynamics with $\ensuremath{\beta}$ constraint generator coordinate method. We obtained two LED states, namely, ${1}_{1}^{\ensuremath{-}}$ state dominant shell-model structure and ${1}_{2}^{\ensuremath{-}}$ large $^{14}\mathrm{C}...

This paper examines whether the average level of human capital in a region affects the earnings of an individual residing in that region in a manner that is external to the individual’s own human capital. I find little evidence of an external effect of human capital, which suggests that human capital spillovers of the form postulated by the new growth literature are unlikely to matter much in p...

Recently we have described the molecular cloning of the genetic determinant coding for the S-fimbrial adhesin (Sfa), a sialic acid-recognizing pilus frequently found among extraintestinal Escherichia coli isolates. Fimbriae from the resulting Sfa+ E. coli K-12 clone were isolated, and an Sfa-specific antiserum was prepared. Western blots indicate that S fimbriae isolated from different uropatho...

The virulence of the uropathogenic E. coli strain 536 (O6:K15:H31) which produces the S-fimbrial adhesin (Sfa+), is serum-resistant (Sre+) and hemolytic (Hly+) and its derivatives were assessed in five different animal models. Cloned hemolysin (hly) determinants from the chromosomes of O6, O18 and O75 E. coli strains and from the plasmid pHly152 were introduced into the spontaneous Sfa-, Sre-, ...

Out of 120 fecal samples collected from diarrheic calves at different localities in AL-Qalyoubia Governorate. 43 were positive for Escherichia coli with an incidence of 35.83%.Serogrouping of E.coli isolates recovered 8 belong to different "O" serogroups which were O55, O111, O26, O153, O8, O18, O86, O157, and "5" isolates were untypable. Antibiogram pattern of isolated E.coli serogroups showed...

Urinary tract infection (UTI) is one of the most common bacterial infections in humans, with uropathogenic Escherichia coli (UPEC) the leading causative organism. UPEC has a number of virulence factors that enable it to overcome host defenses within the urinary tract and establish infection. The O antigen and the capsular polysaccharide are two such factors that provide a survival advantage to ...
