Materials and Methods: Between October 2000 and September 2003, 731 men who underwent open radical retropubic prostatectomy were enrolled in a prospective
outcomes study. The 8-year followup evaluation included the UCLA-PCI, and a survey capturing intracorporeal injection use, satisfaction and reasons for discontinuation. Logistic regression was used to determine associations between intracorporeal injection use and preoperative variables.
Results: The 8-year AZD5153 in vivo self-assessment was completed by 368 (50.4%) men. Of these men 140 (38%) indicated prior or current intracorporeal injection use, with only 34 using intracorporeal injection at 8 years. Overall, 44% of the men were satisfied with intracorporeal injections. Reasons for discontinuation included dislike (47%), pain (33%), return of erection (19%), inefficacy (14%) and no partner (6%). Men trying intracorporeal injections had greater preoperative
UCLA-PCI sexual function scores (75.2 vs 65.62, p = 0.00005) as well as greater decreases in this score at 3 months (p = 0.0002) and 2 years (p = 0.003). Higher preoperative sexual function scores were independently associated with the use of intracorporeal injections in a model adjusted for age, marital status, nerve sparing status and body mass index (OR 1.021, 95% CI 1.008-1.035).
Conclusions: Men pursuing intracorporeal injections have better baseline erectile function and experience greater deterioration in erectile function during the early postoperative period. Despite the high
H 89 efficacy of injections, many men discontinue intracorporeal injections due to dislike or discomfort. Satisfaction rates for intracorporeal injections indicate their long-term role in restoring sexual function in men with post-prostatectomy erectile dysfunction.”
“Current technologies for measuring protein expression across a tissue section are based on MS or in situ detection such as immunohistochemistry. However, due to the inherent molecular complexity of tissue samples and the large dynamic range of protein expression Regorafenib supplier in cells, current approaches are often unable to measure moderate- and low-abundant proteins. In addition, they do not provide information on the physico-chemical properties of the proteins studied. To address these problems, we are developing a new pre-analytic methodology termed layered electrophoretic transfer (LET) that selectively separates and processes proteins from an intact tissue section without compromising important two-dimensional histological information. LET offers two potential advantages over standard techniques: (i) A reduced complexity of the tissue proteome for subsequent analysis; (ii) An opportunity to assess the biochemical status of proteins as they exist in situ.
