Regional chemotherapy for malignant pelvic tumors is disappointing due to the poor tumor response and dose-limiting systemic toxicity. This study was designed to determine whether a novel venous isolation-charcoal hemoperfusion system could limit systemic exposure to chemotherapeutic agents after
A new enzyme immunoassay (EIA) for progesterone receptor (PR) has been developed by Abbott Laboratories. To study the correlation of the results from this new technique with the currently existing tritiated-ligand binding assay [dextran-coated charcoal (DCC) method], cytosols from 70 human breast
A commercial preparation of charcoal-stripped adult bovine serum was used to culture MCF-7 cells in estrogen-free media. Use of this stripped adult bovine serum represents an alternative to calf serum which is in more limited supply, and saves charcoal-stripping of serum in the laboratory, which can
The measurement of E2 receptor (E2R) in human breast cancer cytosol is significantly influenced by conditions usually employed in the dextran-coated charcoal assay. The incubation time and temperature have an influence on the rate of binding and stability of the receptor. Since lower temperatures
Near-infrared-(NIR)-light-triggered photothermal nanocarriers have attracted much attention for the construction of more smart and effective therapeutic platforms in nanomedicine. Here, a multifunctional drug carrier based on a low cost, natural, and biocompatible material, bamboo charcoal
This report presents the clinical effectiveness of multidisciplinary therapy consisting of intraarterial selective chemotherapy, combined with radiofrequency regional hyperthermia (RFRH) in advanced cancer patients. Patients were categorized into the following therapeutic groups: Group I: RFRH
A new dosage form of anticancer agent, mitomycin C adsorbed to activated charcoal (MMC-AC), was evaluated in the rabbit model of hepatic hilar bile duct cancer. The model was produced by inoculation of VX2 cells into the wall of the hepatic hilar bile duct. Histologic examination revealed that the
The mechanism of the antiproliferative effects of progestins on human breast cancer cells is not known. In view of the ability of estrogen to stimulate human breast cancer cell production of peptide growth factors, and since previous studies have suggested that the inhibitory action of progestins is
Attempts to prevent peritoneal carcinomatosis after surgery for gastric cancer by intraperitoneal administration of anticancer drugs have not been successful, largely because the drugs are not retained in the peritoneal cavity. We have assessed the prophylactic efficacy of a delayed-release
Enhanced cytogenetic damage by the homo-aza-steroidal ester of p-bis(2-chloroethyl)-aminophenylacetic acid (ASE) was observed when human lymphocytes in vitro or Ehrlich ascites tumor (EAT) cells in vivo were exposed to nontoxic concentrations of 3-amino-benzamide (3-AB). 3-AB at these concentrations
Previously, we have shown that progestins both stimulate proliferation of the progesterone receptor (PR)-rich human breast cancer cell line T47D and protect from cell death, in charcoal-stripped serum-containing medium. To lessen the variability inherent in different preparations of serum, we
BACKGROUND
Emergence of recurrent cells during androgen-deprivation therapy and intermittent androgen suppression therapy suggest that a subset of prostate cancer cells survive and proliferate in the androgen deprivation condition. Some of the recurrent cells that emerge during the
One hundred and twenty-nine canine mammary tumours of varying histological types were examined for the presence of oestrogen binding protein by the dextran-coated charcoal method with the binding parameters of the reaction determined by Scatchard plots. By this method, 39 per cent of the 129 mammary
BACKGROUND
The incidence of estrogen receptor (ER)-positive breast cancer apparently is increasing. It remains unclear whether this increase is due to an improvement in receptor assay sensitivity, a change in patient characteristics, or a change in tumor biology.
METHODS
The distribution of ER,
MFE-296 endometrial cancer cells express androgen receptors in vitro. These cells, which are tumorigenic in nude mice, are derived from a moderately differentiated human endometrial adenocarcinoma. They express vimentin and the cytokeratins 7, 8, 18, and 19. Karyotyping revealed near-tetraploidy for
