the aim of this study was to develop a novel multifunctional nanoparticle, which encapsulates spion and gemcitabine in plga±peg to form multifunctional drug delivery system. for this aim, super paramagnetic iron oxide nanoparticles (spions) were synthesized and encapsulated simultaneously with gemcitabine (gem) in plga±peg copolymers via w/o/w double emulsification method. optimum size and enca...

Abstract The aim of this study was to develop a novel multifunctional nanoparticle, which encapsulates SPION and Gemcitabine in PLGA±PEG to form multifunctional drug delivery system. For this aim, super paramagnetic iron oxide nanoparticles (SPIONs) were synthesized and encapsulated simultaneously with Gemcitabine (Gem) in PLGA±PEG copolymers via W/O/W double emulsification me...

Gemcitabine (GEM) is currently the standard option for the treatment of pancreatic cancer but its short half-life and rapid metabolism has caused for new modality for delivery of GEM. The purpose of this study was to formulate GEM loaded PEGylated thermosensitive liposomal nanoparticles (GEM-TSLnps) to increase residence time and deliver high payload of GEM to pancreatic cancer cells using mild...

Introduction: To increase the radiation therapy efficiency, two approaches have been employed which include increasing the dose delivery or modifying the biological response to ionizing radiation. This study aimed to modify the biological response to ionizing radiation by combination therapy using radio-sensitizer agent and anticancer drug. Materials and Methods:</str...

BACKGROUND AND OBJECTIVES Gemcitabine (Gem) is far from satisfactory as the first-line regimen for pancreatic cancer, and the emergence of albumin nanoparticles offers new hope for the delivery of Gem. In this study, Gem-loaded human serum albumin nanoparticles (Gem-HSA-NPs) were successfully synthesized, characterized, and tested on a BxPC-3 cell line both in vitro and in vivo. MATERIALS AND...

PURPOSE The purpose of this study is to retrospectively compare the efficacy and tolerability between three regimens for first-line chemotherapy-gemcitabine plus capecitabine (GEM-X), gemcitabine plus erlotinib (GEM-T), and gemcitabine monotherapy (GEM)-in patients with advanced pancreatic cancer. MATERIALS AND METHODS There was a total of 127 patients who underwent chemotherapy for pancreati...

Gaseous elemental mercury (GEM) was monitored at the Niwot Ridge (NWT) Long-Term Ecological Research (LTER) site (Colorado, USA, 40° N) from interstitial air extracted from the snowpack at depths ranging from the snow surface to 10 cm above the soil. A highly dynamic cycling of mercury (Hg) in this mid-latitude snowpack was observed. Patterns were driven by both GEM production in surface snow a...
