OBJECTIVE
The pH-sensitive doxorubicin (DOX)-conjugated and docetaxel (DTX)-conjugated poly(lactic acid)-poly(ethylene glycol)-folate (PLA-PEG-FOL)-based polymeric micelles were developed and characterized in this study.
RESULTS
The drugs were released from the micelles (particle size, ~185 nm) in a
Ovarian cancer is the most lethal gynecologic malignancy, and ovarian cancer stem cells (CSCs) serve a pivotal function in the metastasis and recurrence of ovarian cancer. Multiple previous studies have validated CD133 as a marker of ovarian CSCs. Although salinomycin is a promising therapeutic
A cohort of 1971 chemical workers licensed to handle ethylene oxide was followed up retrospectively from 1940 to 1984 and the vital status of each subject was ascertained. No quantitative information on exposure was available and therefore cohort members were considered as presumably exposed to
The mortality and incidence of cancer in three groups of workers with occupational exposure to ethylene oxide have been assessed. Eight cases of leukemia have occurred among 733 ethylene oxide-exposed workers compared with an expected 0.8 cases. Six cases of stomach cancer have been reported
Nanotubes were prepared by self-assembly of the copolymer using co-solvent evaporation method. The biocompatibility of the nanotubes was assessed in comparison with spherical micelles and filomicelles prepared from poly(ethylene glycol)-poly(L-lactide-co-glycolide) (PEG-PLGA) and poly(ethylene
Mutagenicity tests have shown that the potencies of ethylene oxide and other alkylating agents relative to that of low-LET ionising radiation are approximately the same in different biological systems. In the present study this relationship, the radiation-dose equivalence ("rad-equivalence") of
Ethylene oxide and propylene oxide block copolymers (pluronics) are widely known as agents that promote drug penetration across biological barriers. We have studied the interaction of normal and malignant blood cells with pluronics L61 and P85 that have different hydrophobicity. SP2/0 myeloma cells
Intravenous injection of the gallium chelating agents, N,N'-ethylene bis[2-hydroxy-5-carboxyphenyl-glycine], (COOH-EHPG), or desferrioxamine (DFO) after gallium-67 (67Ga) injection, improved tumour/non-tumour tissue uptake ratios in mice bearing the EMT-6 sarcoma. Six hours post injection of gallium
OBJECTIVE
To assess the radiation dosimetry and biodistribution of (99m)Tc-labeled ethylene dicysteine deoxyglucose ((99m)Tc-EC-DG) in patients with non-small-cell lung cancer (NSCLC).
METHODS
Serial whole-body scans were acquired 0, 2, 4, 6 and 24 h after injection of (99m)Tc-EC-DG (925 MBq) in
PEG-coated beta-FeOOH nanoparticles were prepared through electrostatic complex formation of iron oxide nanoparticles with poly(ethylene glycol)-poly(aspartic acid) block copolymer [PEG-P(Asp)] in distilled water. By dynamic light scattering (DLS) measurement, the nanopaticle size was determined to
Metastatic cancer is responsible for 90% of deaths in world. Usage of nano-carriers improve the delivery and efficacy of chemotherapeutic agents. Recent studies suggest that decoration of the surface of nano-carriers with various targeting agents may further improve their overall therapeutic
Future healthcare requires development of novel theranostic agents that are capable of not only enhancing diagnosis and monitoring therapeutic responses but also augmenting therapeutic outcomes. Here, a versatile and stable nanoagent is reported based on poly(ethylene glycol)-b-poly(l-thyroxine)
A representative poly(beta-amino ester) (PbAE) with biodegradable and pH-sensitive properties was used to formulate a nanoparticle-based dosage form for tumor-targeted paclitaxel delivery. The polymer undergoes rapid dissolution when the pH of the medium is less than 6.5 and hence is expected to
Quantitative estimates of cancer risks from ethylene oxide (ETO) residues were constructed based on 200 retail samples of various spices in New Zealand. Two samples of cinnamon contained detectable ETO. The highest value encountered was 15 ppm. ETO was not detected in the remaining 198 samples.
Pancreatic cancer (PC) is one of the most difficult cancers to treat. Since the current chemotherapy is inadequate and various biological approaches have failed, the need for agents that have a potential to treat PC is pressing. Phospho-valproic acid (P-V), a novel anticancer agent, is efficacious
