The center chosen for this survey is in one of the poorest sections of the city. The homes of most of the children are crowded closely between warehouses, factories, and railroad sidings. The narrow cobble streets always seem to be crowded with heavy trucks, shifting freight cars, and children. A railroad siding just behind the school building is quite a favorite haunt outside of school hours, ...

PURPOSE Endoscopic retrograde ileography (ERIG) is developed in our institute and applied clinically for the diagnosis and assessment of the Crohn's disease activity. We have further improved the technique using 3-dimensional - computed tomography enteroclysis (3D-CTE) and conducted a retrospective study to determine the feasibility and the diagnostic value of endoscopic retrograde 3D-CTE (ER 3...

The human umbilical cord (UC) is usually discarded as biological waste. However, it has attracted interest as a source of cells including endothelial progenitor cells (EPCs) and mesenchymal stem cells (MSCs), which have demonstrated enormous potential in regenerative medicine. The present study describes a convenient protocol that has been developed to sequentially extract these two cell types ...

The most distinctive feature of the Upper Triassic (Carnian) Quaco Formation, coastal New Brunswick, Canada, is the pervasive occurrence of cm-scale circular to elliptical markings and indentations on the cobble surfaces. Also present on many of the cobbles are fractures that radiate from these indentations and spalled clast margins. The smooth-surfaced depressions that occur on most cobbles li...

A variety of gravel- to cobble-sized rocks, recovered from the Mar del Plata (MdP) Canyon area (Western South Atlantic at 38°S) and interpreted as ice-rafted debris, represent first evidence that large icebergs have floated in Falkland (Malvinas) Current southern polar high latitudes far northward. Detailed petrographic analyses identified Antarctic Peninsula, sub-Antarctic islands Scotia Sea, ...

abstract spacing between check dams depends on the stream bed slope, effective height of check dams and slope of deposited sediments behind the check dams. the slope of deposited sediments is more important than the other two factors because of complications in the way of its occurrence and its measurement after several years of dam construction. this research presents the effective factors aff...

This study provides the first report of an egg nursery for Critically Endangered flapper skate Dipturus intermedius and a description habitat, thus contributing towards our understanding essential habitats species. In total, 1,395 cases were recorded (accounting overlapping surveys) in two case collection dives (n = 67 cases), one photogrammetry dive 10 509 drop-down video (DDV) camera drifts 5...
