واکنش رفورمینگ از مهمترین واکنشهای صنعتی و از مهمترین فرآیندها برای تولید بنزین با عدد اکتان بالا وآروماتیکها از نفت بشمار میرود.این واکنشهاروی کاتالیستهای دو عاملی)bifunctional(پلاتین روی پایه آلومینا و یاپلاتین و رنیوم روی پایه آلومینا و غیره صورت می گیرد.دوره عملکرد اینگونه کاتالیستها محدود بوده و درحین عمل تحت عواملی نظیر کلوخه شدن)sintering(، مسموم شدن)poisoning(و فولینگ)fouling(فعالیت آنه...
For the past four years, the University of Delaware's Protocol Engineering Lab has been assisting in the US Army's development of MIL-STD 188-220. Initially UD formally speci ed the Data Link and Intranet layers of 188-220 in Estelle. These Estelle speci cations resulted in more than fty changes/improvements to the 188-220 document. Most importantly, these Estelle speci cations are now an o cia...
External beam radiotherapy (EBRT) treats gross tumors and local microscopic diseases. Radionuclide therapy by radioisotopes can eradicate tumors systemically. Rhenium 188 ((188)Re)-liposome, a nanoparticle undergoing clinical trials, emits gamma rays for imaging validation and beta rays for therapy, with biodistribution profiles preferential to tumors. We designed a combinatory treatment and ex...
Membrane repair of damaged neurons by surfactant poloxamers has been noted in experimental spinal cord injury and in vitro excitotoxicity. We examined poloxamer-188 (P-188)-mediated neuroprotection in a rat model of glutamate toxicity. Quinolinate was infused into the striatum followed 10 min and 4 h later by P-188 administered either i.v. or intracisternally (i.c.), or by vehicle. Mean neurona...
PURPOSE In this study, the (188)Re-labeled PEGylated nanoliposome ((188)Re-liposome) was prepared and evaluated as a therapeutic agent for glioma. MATERIALS AND METHODS The reporter cell line, F98(luc) was prepared via Lentivector expression kit system and used to set up the orthotopic glioma-bearing rat model for non-invasive bioluminescent imaging. The maximum tolerated dose applicable in F...
BACKGROUND Due to their nanometric scale (50 nm) along with their biomimetic properties, lipid nanocapsules loaded with Rhenium-188 (LNC(188)Re-SSS) constitute a promising radiopharmaceutical carrier for hepatocellular carcinoma treatment as its size may improve tumor penetration in comparison with microspheres devices. This study was conducted to confirm the feasibility and to assess the effic...
The incidence of melanoma is rising, and therapeutic options for metastatic melanoma are limited. We report the results of experimental melanoma therapy with 188-Rhenium-labeled melanin-binding decapeptide ((188)RE-HYNIC-4B4) and a comprehensive safety evaluation of this treatment. (188)RE-HYNIC- 4B4 bound only to nonviable eumelanotic MNT1 and pheomelanotic SK-28-MEL human melanoma cells in vi...
BACKGROUND Nanoliposomes are designed as carriers capable of packaging drugs through passive targeting tumor sites by enhanced permeability and retention (EPR) effects. In the present study the biodistribution, pharmacokinetics, micro single-photon emission computed tomography (micro-SPECT/CT) image, dosimetry, and therapeutic efficacy of (188)Re-labeled nanoliposomes ((188)Re-liposomes) in a C...
