Urinary incontinence （UI） and erectile dysfunction （ED） are both very prevalent conditions. Insertion of an artificial urinary sphincter （AUS） and penile prosthesis （PP） is an effective and proven method of treatment for both conditions. With advancing age, as well as with increasing populations of patients radically treated for prostate cancer, the occurrence of both conditions found in the same patient is increasing. The purpose of this article was to analyze the available evidence for simultaneous surgical management of male ED and UI using prosthetic devices. The existing literature pertaining to dual implantation of AUS and PP was reviewed. The concomitant insertion of the PP with the male perineal sling was also considered. Concurrent ED and UI are increasingly seen in the post radical prostatectomy population, who are often younger and less willing to suffer with these conditions. Insertion of an AUS and PP, either simultaneously or as a two-stage procedure, appears to be a safe, efficacious and long-lasting method of treatment. The improvements in design of both the AUS and PP as well as the development of the single transverse scrotal incision have made simultaneous insertion of these prostheses possible. Dual implantation of the PP and male sling looks promising in a selected population. In conclusion, the insertion of the AUS and PP for the treatment of concurrent UI and ED is safe and effective. Simultaneous insertion of these prostheses in the same patient offers potential advantages in operative and recovery time and is associated with high patient satisfaction. Combination therapy should therefore be included in the arsenal of treatment of these conditions.

Insect herbivores can regulate their food intake by mixing food sources with different nutrient content, but face the resulting challenge of ingesting various plant secondary metabolites. How insects deal with toxins in a complex nutrient environment is unclear. Here we investigated the influence of a classic plant secondary metabolite, allyl glucosinolate (sinigrin), and its hydrolyzed product allyl isothiocyanate (AITC), on the development of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) when fed on diets with different protein-to-carbohydrate (p : c) ratios. We also examined the effects of these toxins on larval biochemistry, by chemically analyzing the frass produced by insects feeding on the different diets. As expected, AITC had a greater negative effect than sinigrin on H. armigera life-history traits. However, AITC at low concentration appeared to have a positive effect on some traits. Both sinigrin and AITC-induced detoxification activity in the gut, and the reaction was related to diet protein concentration. High-protein diets can provide the required free amino acid, especially cysteine, needed for the detoxification process. The nutrient content of the diet influences how plant secondary metabolites are handled, and the use of artificial diets in experiments investigating the metabolic fate of plant secondary compounds needs to be carefully evaluated.

It has been a long-standing question whether dewetting of polymer film from non-wettable substrate surfaceswherein the bicontinuous morphology never forms in the dewetting film is due to spinodal instability or heterogeneousnucleation. In this experiment, we use a simple method to make the distinction through introduction of topographical defectsof the films by rubbing the sample surface with a rayon cloth. Spinodal dewetting is identified for those films that dewet by acharateristic wavevector, q, independent of the density of rubbing-induced defects. Heterogeneous nucleation, on the otherhand, is identified for those with q increasing with increasing density of defects. our result shows that PS films on oxidecoated silicon with thickness less than ≈ 13 nm are dominated by spinodal dewetting, but the thicker films are dominated bynucleation dewetting. We also confirm that spinodal dewetting does not necessarily lead to a bicontinuous morphology in thedewetting film, contrary to the classic theory of Cahn.
