Purpose:We describe the preclinical pharmacology and antitumor activity of GDC-0068, a novel highly selective ATP-competitive pan-Akt inhibitor currently in clinical trials for the treatment of human cancers. Experimental Design: The effect of GDC-0068 on Akt signaling was characterized using specific biomarkers of the Akt pathway, and response to GDC-0068 was evaluated in human cancer cell lin...
GDC-0834, a Bruton’s tyrosine kinase inhibitor investigated as a potential treatment of rheumatoid arthritis, was previously reported to be extensively metabolized by amide hydrolysis such that no measurable levels of this compound were detected in human circulation after oral administration. In vitro studies in human liver cytosol determined that GDC-0834 (R)-N-(3-(6-(4-(1,4-dimethyl-3-oxopipe...
Gadanium doped cerium oxide ceramic (GDC) is widely used as solid electrolytes in solid oxide fuel cells because of its high oxygen ion conductivity. In this study, the effect of addition of nano CuO as a sintering aid on the properties of GDC electrolyte were investigated. For this purpose, 0.2, 0.5, and 1% mole of nano Cuo was added to GDC ceramics, which was synthesized by the solid-state me...
PURPOSE ActivatingPIK3CAgenomic alterations are frequent in head and neck squamous cell carcinoma (HNSCC), and there is an association between phosphoinositide 3-kinase (PI3K) signaling and radioresistance. Hence, we investigated the therapeutic efficacy of inhibiting PI3K with GDC-0032, a PI3K inhibitor with potent activity against p110α, in combination with radiation in HNSCC. EXPERIMENTAL ...
PURPOSE Oncogenic signaling in gastrointestinal stromal tumors (GIST) is sustained via PI3K/AKT pathway. We used a panel of six GIST xenograft models to assess efficacy of GDC-0941 as single agent or in combination with imatinib (IMA). EXPERIMENTAL DESIGN Nude mice (n = 136) were grafted bilaterally with human GIST carrying diverse KIT mutations. Mice were orally dosed over four weeks, groupe...
Gastric duplication cysts (GDC) are rarely diagnosed in adults, but previous cases have been associated with malignancy. We present a case of gastrointestinal stromal tumor (GIST) arising from a GDC in a 71-year-old woman who presented with 3 years of early satiety, anorexia, abdominal distention, and weight loss. Abdominal CT showed a 9.3 x 5.2 x 9.5-cm well-circumscribed cystic mass arising 3...
به منظور مطالعه نقش فرآیند نانوساختارسازی بر کارآیی آند سرمت Ni/GDC برای پیل سوختی اکسید جامد دما پایین (LT-SOFC)، ریزساختار آند NiO/Ce0.8Gd0.2O2-δ (NiO/GDC20) بوسیله محلول کلرید پالادیم، آغشتهسازی شد. تاثیر آغشتهسازی Pd بر کارآیی آندی، با استفاده از آنالیز طیفبینی امپدانس الکتروشیمیایی (EIS)، به کمک پیل پایه- الکترولیتی Ni-GDC/GDC/Pt در دمای °C 600-400، مورد بررسی قرار گرفت. ارتقاء ریزساختا...
In the present work, Gadolinium Doped ceria (GDC) based solid electrolyte was successfully synthesized through wet chemical method to operate at intermediate temperature (500–700°C) for SOFCs. DSC study revealed the formation of GDC phase at 900°C during calcination. The crystal structure of GDC was identified as cubic fluorite phase and the crystallite size was found to be around 23 nm....
Cermet films consisting of Ni, BaCe0.4Zr0.4Y0.2O3−δ (BCZY), and Gd0.1Ce0.9Ox (GDC), specifically, 60 wt%Ni–BCZY, wt%Ni–BCZY–GDC, wt%Ni–GDC, were formed on BCZY electrolyte supports as anodes proton ceramic fuel cells (PCFCs). The Ni grain size in these after sintering at 1450 °C was around 2 μm. GDC addition did not affect the case matrix. anodic properties greatly depended oxide phase composit...
BACKGROUND Recent evidence from in vitro and in vivo studies has demonstrated that aberrant reactivation of the Sonic Hedgehog (SHH) signaling pathway regulates genes that promote cellular proliferation in various human cancer stem cells (CSCs). Therefore, the chemotherapeutic agents that inhibit activation of Gli transcription factors have emerged as promising novel therapeutic drugs for pancr...
