OBJECTIVE NADH/NADPH oxidase is an important source of reactive oxygen species (ROS) in the vasculature. Recently, we demonstrated that p22(phox), an essential component of this oxidase, was expressed in human coronary arteries and that its expression was enhanced with the progression of atherosclerosis. The present study was undertaken to investigate its functional importance in the pathogenes...

We show that the generalized Yang–Mills system with Hamiltonian H=(p12+p22)/2+V(q1,q2) where V=1/2(aq12+bq22)+(cq14+2eq12q22+dq24)/4 is not completely integrable Darboux first integrals.

Pediatric mixed-lineage leukemia (MLL)-rearranged acute monoblastic leukemia with t(9;11)(p22;q23) has a favorable outcome compared with other MLL-rearranged AML. The biologic background for this difference remains unknown. Therefore, we compared gene expression profiles (GEPs; Affymetrix HGU133 + 2.0) of 26 t(9;11)(p22;q23) patients with 42 other MLL-rearranged AML patients to identify differe...

The 14 Hind111 cleavage sites on P22 DNA have been mapped. Hind111 cleavage sites were located relative to EcoRI sites by determining the molecular weights and map order of fragments produced by HindIII, or Hind111 and EcoRI digestion. Molecular weights were estimated from the electrophoretic mobility of fragments. The Hind111 fragment order was established by Hind111 cleavage of segments of th...

Homologous recombination in meiosis is initiated by the programmed induction of double strand breaks (DSBs). Although the Drosophila Spo11 ortholog Mei-W68 is required for the induction of DSBs during meiotic prophase, only one other protein (Mei-P22) has been shown to be required for Mei-W68 to exert this function. We show here that the chromatin-associated protein Trade Embargo (Trem), a C2H2...

The opdA gene of Salmonella typhimurium encodes an endoprotease, oligopeptidase A (OpdA). Strains carrying opdA mutations were deficient as hosts for phage P22. P22 and the closely related phages L and A3 formed tiny plaques on an opdA host. Salmonella phages 9NA, KB1, and ES18.h1 were not affected by opdA mutations. Although opdA strains displayed normal doubling times and were infected by P22...

Salmonella phage P22 has been used in the construction of three sorts of specialized transducing phage: P22 proAB, P22 proABlac and P22 argF. The bacterial genes carried are derived from E. coli K12. Since E. coli and Salmonella chromosomes recombine very poorly, E. coli genes cannot be transduced into Salmonella recipients by P22‘s generalized transduction mechanism. Therefore, stable inherita...

Objective: There are a number of medicinal plant products which has been used to treat various immunological diseases. Out of these medicinal plants, Calamus rotang has shown several medicinal properties including anti-viral, anti-diabetic, anti-inflammatory effects. Normally, the roots of C. rotang are used in various ailments to cure piles, burning sensation, cough, leprosy and bleeding disor...

DNA polymerase delta (pol delta) plays an essential role in DNA replication, repair, and recombination. We have purified pol delta from Schizosaccharomyces pombe more than 10(3)-fold and demonstrated that the polymerase activity of purified S. pombe pol delta is completely dependent on proliferating cell nuclear antigen and replication factor C. SDS/PAGE analysis of the purified fraction indica...
