Fabrication of Highly Oriented Multilayer Films of Picene and DNTT on Their Bulklike Monolayer.

Highly oriented, multilayer molecular films of picene and dinaphtho[2,3-:2',3'-]thieno[3,2-]thiophene (DNTT) molecules with the long axis parallel to the substrate (parallel configuration, hereafter) were fabricated on their characteristic bulklike monolayer. These molecules form a dense monolayer with a bulklike molecular arrangement on metal surfaces such as Au(111), which allows further stacking of parallel molecules. Indeed, upon adsorption of picene and DNTT on these dense monolayers, growth of straight islands of multilayer without the dendritic layer was observed.

Intracavernous injection of prostaglandin E1 is effective in patients with erectile dysfunction not responding to phosphodiseterase 5 inhibitors.

We report on 64 patients who did not achieve erections adequate for satisfactory sexual intercourse from among a total of 243 patients who were prescribed PDE5 inhibitors for erectile dysfunction (ED). Intracavernous injection (ICI) of PGE was performed in this non-responder group. An ICI of 20 or 40 mcg of PGE1 in 1 ml saline was performed and the responses evaluated.

Minimal invasiveness and effectivity of subinguinal microscopic varicocelectomy: a comparative study with retroperitoneal high and laparoscopic approaches.

Aim: The standard management of varicocele repair is the subject of ongoing controversy. We retrospectively evaluated three surgical methods of varicocele treatment to determine the minimally invasive and most effective procedure.

Methods: We performed 144 varicocelectomies on infertile patients with left clinical varicocele.

Clinical results of one-stage urethroplasty with parameatal foreskin flap for hypospadias.

We investigated the usefulness of one-stage urethroplasty by the parameatal foreskin flap method (OUPF procedure), which is useful for repairing all types of hypospadias. Between June 1992 and March 2001, the OUPF procedure was performed on 18 patients with hypospadias: 10 patients with distal and 8 with proximal hypospadias. The follow-up periods ranged from 33-75 months, with an average of 52 months.
