جداسازی گازهای نیتروژن – متان از جمله فرآیندهای بسیار مهم و پرکاربرد در زمینه ارتقای گاز طبیعی و افزایش ارزش حرارتی آن می باشد. استفاده از غشاهای شبکه آمیخته در این جداسازی می تواند به کاهش مصرف انرژی کمک فراوانی کند. در این راستا، در این تحقیق غشاهای شبکه آمیخته از پلی کربنات (pc) حاوی نانوذرات زئولیت a و همچنین غشای pc حاوی نانوذرات zsm-5 ، تهیه و رفتار تراوایی و گزینش پذیری آنها برای گازهای ...
Five different crude polysaccharides from guava seed (GSPS), bitter buckwheat (BBPS), common buckwheat (CBPS), red Formosa lambsquarters (RFLPS), and yellow Formosa lambsquarters (YFLPS) were isolated to treat human prostate cancer PC-3 cells via direct action or tumor immunotherapy. The splenocyte- and macrophage-conditioned media (SCM and MCM) were prepared using individual selected polysacch...
PTHrP is the major pathogenetic factor for hypercalcemia in several malignancies including prostate cancer. In the current study, we have assessed the ability of androgens to regulate PTHrP production in androgen-insensitive human prostate cancer cells PC-3 and cells transfected with androgen receptor (PC-3T). Androgen responsiveness caused a marked decrease in PC-3T cell growth, and treatment ...
PURPOSE To evaluate the feasibility of rapid free-breathing phase-contrast MRI (PC-MRI) at different in-plane resolutions combined with sensitivity encoding (SENSE) for flow quantification in the great arteries in healthy adult volunteers. METHODS In 13 volunteers (mean age 33.0 +/- 7.4 years), blood flow rates in the pulmonary artery (Qp), ascending aorta (Qs), and flow ratio Qp/Qs were dete...
We previously reported the tumor-suppressive activity of insulin-like growth factor binding protein-related protein 1 (IGFBP-rP1) through induction of apoptosis in human prostate cancer cells. The aim of this study was to investigate the effects of IGFBP-rP1 for radiosensitivity and chemosensitivity in hormone-refractory human prostate PC-3 cancer cells. Five assays were performed using PC-3 ce...
The IGF axis has been implicated in the pathogenesis of benign prostatic hyperplasia (BPH) via the paracrine action of IGFs and IGF-binding proteins (IGFBPs). In this study, we examined the regulation of cell growth and IGFBP-3 secretion by transforming growth factor-beta (TGF-beta) in prostatic stromal cell (PC-S) cultures from histologically normal tissues and tissues from BPH. PC-S cultures ...
Endogenous 2-arachidonoylglycerol (2-AG) is antiinvasive in androgen-independent prostate carcinoma (PC-3) cells. Invasion of PC-3 cells is also inhibited by exogenously added noladin ether, a non-hydrolyzable analog of 2-AG. In contrast, exogenous 2-AG has the opposite effect. Cell invasion significantly increased with high concentrations of exogenous 2-AG. In PC-3 cells, arachidonic acid (AA)...
Background: Prostate cancer (Pca) is a heterogeneous disease, and current treatments are not based on molecular stratification. Poly(adenosine diphosphate [ADP]-ribose) polymerase (PARP) inhibitors have recently been found to be remarkably toxic to cells with defects in homologous recombination, particularly cells with BRCA-mutated backgrounds. Therefore, this preliminary study was designed to ...
