Pleuropulmonary blastoma (PPB) is a rare aggressive malignant tumor of infancy and early childhood. The tumor arises in the lung and pleura and is regarded as a pulmonary dysontogenetic or embryonic neoplasm. Four types are defined in literature. Type I PPB is a rare, cystic lung neoplasm in infants characterized by subtle malignant changes and a good prognosis. Recurrences after type I PPB are...

The collective behavior of K$^0_\mathrm{S}$ and $\Lambda/\bar{\Lambda}$ strange hadrons is studied by measuring the elliptic azimuthal anisotropy ($v_2$) using scalar-product multiparticle correlation methods. Proton-lead (pPb) collisions at a nucleon-nucleon center-of-mass energy $\sqrt{s_\mathrm{NN}}$ = 8.16 TeV lead-lead (PbPb) 5.02 collected CMS experiment LHC are investigated. Nonflow effe...

The purpose of this study was to investigate the advantages and disadvantages of Participatory Plant Breeding (PPB). Seventy-six breeders were randomly selected from among 95 breeders who were working at the Seed and Plant Improvement Institute, Karaj, Iran. Data were collected by a questionnaire as the main data collection instrument. The face and content validity of the questionnaire was appr...

With respect to the ambient nitric oxide values, we have examined their effect on exhaled nitric oxide. Since there was no significant influence of ambient nitric oxide levels ,20 ppb on the fraction of exhaled nitric oxide values in our study population (figs 2 and 3), we decided to include all children with ambient nitric oxide levels ,20 ppb in the analyses. When the analyses were repeated, ...

Control of the pattern of cell division is essential for the proper development of multicellular organisms. In animal cells, cytokinesis is mediated by a contractile ring in which the cleavage force is produced by an acto-myosin system. Furthermore, the future site of cell division in animal cells (the site where contraction starts in the cell cortex) is determined by the position of the aster ...

There have been increasing human health and ecological concerns about ionic perchlorate (ClO4-) since it was detected in drinking water sources in 1997. Perchlorate is known to affect thyroid function, causing subsequent hormone disruption and potential perturbations of metabolic activities. According to current estimates, perchlorate is found in the surface of groundwater of 14 states, includi...

We describe measurements of total peroxy nitrates (6PNs), NO2, O3 and several aldehydes at Granite Bay, California, during the Chemistry and Transport of the Sacramento Urban Plume-2001 (CATSUP 2001) campaign, from 19 July–16 September 2001. We observed a strong photochemically driven variation of 6PNs during the day with the median of 1.2 ppb at noon. Acetaldehyde, pentanal, hexanal and methac...
