Measurements of subtunical calcifications, septal fibrosis, tunical thickening
(tunica thickness greater than 2 mm) and intracavernous fibrosis were made. Progression to surgery was determined from the medical record.
Results: In this cohort (mean patient age 53.8 years, range 20 to 78) 31% of patients had calcifications, 50% AZD1480 mouse had tunical thickening, 20% had septal fibrosis and 15% had intracavernous fibrosis. Overall 25% of the cohort progressed to surgical intervention after an average followup of 1.25 years (range 0 to 7.6). Patients who underwent surgery were more likely to have subtunical calcifications present at the first clinic visit (OR 1.75, 95% CI 1.16-2.62). No other sonographic characteristics were associated with progression to surgery. After adjustment for age, marital status, degree of curvature, additional penile deformity, difficulty with penetration, ability
to have intercourse and prior treatment for Peyronie’s disease, calcifications were strongly associated with progression to surgery (OR 2.75, 95% CI 1.25-3.45).
Conclusions: In a large cohort GSK923295 of patients with Peyronie’s disease the presence of sonographically detected sub-tunical calcifications during the initial office evaluation was independently associated with subsequent surgical intervention.”
“Amyloid-beta peptides (A beta) generated by proteolysis of the p-amyloid precursor protein (APP) by beta- and gamma-secretases play an
important role in the pathogenesis of Alzheimer’s disease (AD). There is mounting evidence that the lipid matrix of neuronal cell membranes plays an important role in the accumulation of A beta peptides into senile plaques, one of the hallmarks of AD. With the aim to clarify the molecular basis of the interaction between A beta and cellular membranes, we investigated the effects of various phospholipids (PLs) and a PL-rich diet on A beta production. Here we show that modulation of A beta production and A beta 42:40 ratio is not limited to individual fatty acids, rather it is the composition of the PLs of the membrane MTMR9 bilayer, that influences the specificity and level of the regulated intramembranous proteolysis of APP by the gamma-secretase complex. We show that A beta levels in the conditioned media, in response to some of the PL supplements, is increased in the center and decreased on either side of a graph that resembles bell-shaped distribution. This means that the PLs have less of a tendency to produce unusually extreme effects on A beta production in SP-C99 transfected Cos-7 cultured cells. We proposed a mechanism-based hypothesis to rationalize PLs’ effects on A beta production. (C) 2010 Elsevier Ireland Ltd. All rights reserved.”
