Of 3,200 cultures of Escherichia coli isolated from streams in Pennsylvania over a 7-year period, 82.46% or 2,639 were O serogrouped. The largest number of cultures (33.4%) belonged to O groups 1 to 26, and the second highest number (16.8%) belonged to O groups 60 to 88. The individual E. coli O groups most frequently isolated were ADO3, 18ac, 2a, 3, 7, 73, 139, and OX13. Practically every know...

Interleukin-11 (IL-11) displays megakaryopoietic activity. We constructed super-cytokine Hyper- IL11 (H11) by linking soluble IL-11 receptor α (sIL-11Rα) with IL-11, which directly targets β-receptor (gp130) signal transducing subunit. The effects of H11 on hematopoiesis with a focus on megakaryopoiesis were studied. The expansion, differentiation and type of colony formation of cord blood prog...

The incidence of cancer is constantly increasing. Chemo/radiotherapy is one of major methods of treating cancer. Although adverse chemo/radiotherapy events, such as anemia and neutropenia, can be successfully cured, thrombocytopenia is still problematic. We constructed the Hyper-IL11 (H11) cytokine by linking soluble interleukin 11 receptor alpha (sIL-11Ralpha) with IL-11. In vivo H11 activity ...

Three human rhabdomyosarcoma cell lines (Rh10, Rh18, and Rh28) have been established from three independently derived xenografts. These lines have been characterized as mesenchymal in origin (reactivity to desmin and vimentin antibodies) and as expressing a human fetal muscle surface antigen recognized by monoclonal antibody 5.1 H11. Measurable levels of creatine phosphokinase have been detecte...

Shiga toxin-producing E. coli (STEC) are isolated from human patients with bloody diarrhea, hemorrhagic colitis (HC), and hemolytic uremic syndrome (HUS). In the last years, the infections with non-O157 serotypes are increasing their frequency of association with human disease. STEC produce Shiga toxin (Stx) and other virulence factors that could contribute to human pathogenesis. Cattle are the...

Escherichia coli strains of serogroup O26 comprise two distinct groups of pathogens, characterized as enteropathogenic E. coli (EPEC) and enterohemorrhagic E. coli (EHEC). Among the several genes related to type III secretion system-secreted effector proteins, espK was found to be highly specific for EHEC O26:H11 and its stx-negative derivative strains isolated in European countries. E. coli O2...

Let H = ( H11 H12 H∗ 12 H22 ) be an n×n positive semidefinite matrix, where H11 is k×k with 1 ≤ k < n. The generalized Schur complement of H11 in H is defined as S(H) = H22 −H∗ 12H † 11H12, where H 11 is the Moore-Penrose generalized inverse of H11. It has the extremal characterizations S(H) = max { W : H − ( 0k 0 0 W ) ≥ 0,W is (n− k)× (n− k) Hermitian } and S(H) = min {[Z|In−k]H[Z|In−k] : Z i...

Enterohemorrhagic Escherichia coli (EHEC) O26:H11, a serotype within Shiga toxin-producing E. coli (STEC) that causes severe human disease, has been considered to have evolved from attaching and effacing E. coli (AEEC) O26:H11 through the acquisition of a Shiga toxin-encoding gene. Targeted amplicon sequencing using next-generation sequencing technology of 48 phylogenetically informative single...

By subtractive hybridization, we found a significant increase in H11 kinase transcript in large mammalian models of both ischemia/reperfusion (stunning) and chronic pressure overload with hypertrophy. Because this gene has not been characterized in the heart, the goal of the present study was to determine the function of H11 kinase in cardiac tissue, both in vitro and in vivo. In isolated neona...
