Testosterone administration in rats is a suitable tool for investigating hormone dependent benign Nepicastat ic50 prostatic hyperplasia. We performed a comparison experiment between Serenoa repens and the lycopene-Se-Serenoa repens combination on prostate growth induced in rats by testosterone administration.
Materials and Methods: Rats were treated daily with testosterone propionate (3 mg/kg subcutaneously) or its vehicle for 14 days. Testosterone administered animals were randomized to receive vehicle, Serenoa repens (25 mg/kg subcutaneously)
or the combination of lycopene (3 mg/kg subcutaneously), Se (3 mg/kg subcutaneously) and Serenoa repens for 14 days. The rats were sacrificed and
the prostate was removed for analysis.
Results: Lycopene-Se-Serenoa repens was more effective than Serenoa repens alone for decreasing prostate weight and hyperplasia, augmenting pro-apoptotic Bax and caspase-9, and blunting anti-apoptotic Bcl-2 mRNA. Lycopene-Se-Serenoa repens also markedly decreased epidermal growth factor and vascular endothelial growth factor expression.
Conclusions: The data indicate that the Stattic ic50 lycopene-Se-Serenoa repens combination is superior to Serenoa repens alone for decreasing hormone dependent prostatic growth.”
“Recent studies have shown that PLA2G6 is a causative gene for PARK14-linked autosomal recessive early-onset complicated dystonia-parkinsonism, early-onset parkinsonism with frontotemporal dementia and autosomal recessive early-onset Parkinsonism without added complicated clinical features. In order to investigate the characteristics of PLA2G6 gene mutations in Chinese selleck screening library sporadic early-onset parkinsonism (FOP) patients, we performed polymerase chain reaction
and DNA direct sequencing on a cohort of sporadic EOP patients from Chinese population. In this study, we found a novel heterozygous varient (p.G679V). Bioinformatics demonstrates that p.G679V exhibits highly conserved residues across species, which hints it might be a pathogenic mutation. Our result indicated that PLA2G6 mutations might not be a main cause of Chinese sporadic EOP. (C) 2012 Elsevier Ireland Ltd. All rights reserved.”
“Objective: To test if the covariance of hypothalamus-oituitary-adrenal (HPA) axis and subjective-psycho logical responses to stress is dependent on different dynamics of these systems. Although stress theories typically assume substantial correlations of psychological and endocrine stress responses, studies have produced inconsistent results. One reason for this might be imperfect coupling of the different stress response systems. However, inconsistent correlations might also be a result of different on-/offsets of these stress responses, i.e., specific dynamics of the systems.
