objective(s) the aim of this study was to evaluate the expressions of two angiogenic immune-markers (cd-31 and vegf), and one proliferative immune-marker (ki-67) in oral pyogenic granulomas (pg), hemangiomas (hem) and inflammatory gingivitis (ig). materials and methods sixty cases of pg, hem and ig (twenty cases each) were examined. immunohistochemical (ihc) staining was performed based on rout...

Deletion derivatives of phage Mu which replicate as multicopy plasmids, and also transpose and package like Mu, have been developed for the in vivo cloning of bacterial genes. We show here that these miniMu plasmid phage are also efficient at generalized transduction and that both in vivo cloning and generalized transduction of a given gene can be accomplished in a single experiment.

emerging data suggest that measurement of serum ige to peanut components can be clinically helpful and more accurate than ige to whole peanut to predict peanut allergy. not all studies have used prospective samples, multiple components and oral challenges. currently, there are no data on this topic involving italian children. 32 patients (23 males; median age 9 years) with reported history for ...

The transmission performance for a downlink mobile WiMAX system with multiuser multiple-input multiple-output (MU-MIMO) systems in a computer simulation and field experiment is described. In computer simulation, a MU-MIMO transmission system can be realized by using the block diagonalization (BD) algorithm, and each user can receive signals without any signal interference from other users. The ...

The MuA transposase of phase Mu is a large modular protein that plays a central role in transposition. We show that the Mu end DNA-binding domain, I beta gamma, which is responsible for binding the DNA attachment sites at each end of the Mu genome, comprises two subdomains, I beta and I gamma, that are structurally autonomous and do not interact with each other in the absence of DNA. The soluti...

The two title compounds, di-mu-bromo-bis{[2,6-bis(pyrazol-1-yl-kappaN(2))pyridine-kappaN](perchlorato-kappaO)copper(II)}, [Cu(2)Br(2)(ClO(4))(2)(C(11)H(9)N(5))(2)], (I), and [2,6-bis(pyrazol-1-yl)pyridine]dibromocopper(II), [CuBr(2)(C(11)H(9)N(5))], (II), were synthesized by only slight modifications of the same reaction; compound (II) was formed by adding one molar equivalent of pyrazole (C(3)...

The Houghton groups H1,H2,… are a family of infinite groups. In 1977 Wiegold showed that H3 was invariably generated (IG) but H1⩽H3 not. A natural question is then whether the H2,H3,… all IG. also ends by saying that, in examples he had found an IG group with subgroup not IG, never finite index. Another there index this note we prove, for each n∈{2,3,…}, Hn and its subgroups independent work Mi...
