endourologic pyeloplasty is being a substitute of open pyeloplasty in management of ureteropelvic junction obstruction. this procedure can be done in different manners like balloon dilation, cold knife and electrosurgical endoureterotomy, accucise and lasers.a 47 year old woman referred with history of previous open pyeloplasty. hydronephrosis of right kidney with unremarkable t ½ was found in ...

Forward Osmosis (FO) polyamide thin-film composite membranes have been prepared by interfacial polymerization using commercial UF polyethersulfoneas membrane support. Different interfacial polymerization times (10s, 30s and 60s) in the organic solution containing trimesoyl chloride (TMC) at constant mphenylenediamine (MPD) concentration (2% w/v) were studied. The synthesized polyamide membranes...

A series of hairpin pyrrole-imidazole polyamide-fluorescein conjugates were synthesized and assayed for cellular localization. Thirteen cell lines, representing 11 human cancers, one human transformed kidney cell line, and one murine leukemia cell line, were treated with 5 microM polyamide-fluorescein conjugates for 10-14 h, then imaged by confocal laser scanning microscopy. A conjugate contain...

The key in selective laser sintering (SLS) of polyamide 12 for exceeding the cusp from a prototyping to a serial production technique poses the long-term behavior of such components. The improvement of additive manufacturing technologies is attended by the enlargement of the possible ranges of use. The crucial obstacle for their actual use is the ignorance of the long-term properties and the co...
