BACKGROUND
Ethylene oxide (ETO) is a sterilant gas considered to be a human carcinogen, due primarily to excess hematopoietic cancer in exposed cohorts. ETO causes mammary tumors in mice, and has been associated with breast cancer incidence in one small epidemiologic study.
METHODS
We have studied
For the first time, National Health and Nutrition Examination Survey released data on ethylene oxide (ETO) into public domain for US children aged 6-11 years, adolescents aged 12-19 years, and adults aged ≥ 20 years for 2013-2016. This study was undertaken to evaluate the associations between
To conduct a systematic literature review and meta-analysis of studies of lympho-hematopoietic cancers (LHC) and breast cancer risk among persons occupationally exposed to ethylene oxide (EO).We performed a literature search for articles available in PubMed OBJECTIVE
Intestinal toxicity and low levels of systemic drug exposure are among the major problems associated with tumour therapy. We have developed poly (ethylene oxide)-poly (propylene oxide)-poly (ethylene oxide) (PEO-PPO-PEO) micelles loaded with irinotecan hydrochloride (CPT-11) hoping to
This study was carried out to evaluate and compare the biodistribution profile of tamoxifen when administered intravenously (i.v.) as a simple solution or when encapsulated in polymeric nanoparticulate formulations, with or without surface-stabilizing agents. Tamoxifen-loaded, poly(ethylene
Traceable poly(ethylene oxide)-poly(ester) micelles were developed through chemical conjugation of a near-infrared (NIR) dye to the poly(ester) end by click chemistry. This strategy was tried for micelles with poly(ε-caprolactone) (PCL) or poly(α-benzyl carboxylate-ε-caprolactone) (PBCL) cores. The
In this study, a new poly(lactic acid)-poly (ethylene oxide)-Arg-Gly-Asp (PLA-PEO-RGD) derivative was synthesized, and paclitaxel-loaded PLA-PEO-RGD micelles were prepared by this derivative. The solubility assay showed that micelles mixed with Pluronic F-68 as surfactant could increase the
OBJECTIVE
To extend mortality follow up from 1987 to 1998 for cohort of 18 235 men and women exposed to ethylene oxide.
METHODS
Standard mortality follow up, life table and Cox regression analysis.
RESULTS
There were 2852 deaths, compared with 1177 in the earlier 1987 follow up. There was no overall
To develop delivery systems for efficient siRNA delivery to breast cancer.
Poly(ethylene oxide)-block-poly(ϵ-caprolactone-grafted-spermine) (PEO-b-P(CL-g-SP)) micelles were modified with cholesterol group in their core and with RGD4C peptide on their shell. Transfection efficiency of complexed MCL-1
The most recent epidemiological data on individual workers in the NIOSH and updated UCC occupational studies have been used to characterize the potential excess cancer risks of environmental exposure to ethylene oxide (EO). In addition to refined analyses of the separate cohorts, power has been
Novel poly(ethylene oxide)-graft-doxorubicin (PEO-g-DOX) prodrugs with DOX covalently conjugated to PEO via a pH-sensitive hydrazone bond were developed. PEO-g-DOX conjugates could be readily prepared in the following steps: (i) anionic ring-opening copolymerization of ethylene oxide (EO) and allyl
BACKGROUND
Cytogenetic changes associated with ethylene oxide (ETO) exposure at a worksite prompted a study of cancer incidence in that cohort.
METHODS
Cancer incidence through 31 December 1987 was ascertained in a cohort of 1132 individuals employed at the worksite at any time from 1 July 1974
Previous analyses of mortality were conducted in a large cohort of ethylene oxide (EtO) exposed workers employed at 13 sterilization facilities throughout the U.S. and followed from the start of operation through 1998. Statistically significant elevated mortality was reported from To assess whether cancer incidence, mainly from lymphohaematopoietic tumours and breast cancer, and mortality were increased in a cohort of Swedish sterilant workers exposed to low levels of ethylene oxide (EtO), updated with 16 more years of follow up.
The mortality and cancer incidence 1972-2006
