No influence of magnetic fields on cell cycle progression using conditions relevant for patients during MRI.
2003
The purpose of this study was to examine whether exposure to magnetic fields (MFs) relevant for magnetic resonance imaging (MRI) in clinical routine influences cell cycle progression in two tumor cell lines in vitro. HL60 and EA2 cells were exposed to four types of MFs: (i) static MF of 1.5 and 7.05 T, (ii) extremely low frequency magnetic gradient fields (ELFMGFs) with ± 10 mT/m and 100 Hz, as well as ± 100 mT/m and 100 Hz, (iii) pulsed high frequency MF in the radiofrequency (RF) range (63.6 MHz, 5.8 μT), and (iv) a combination of (i–iii). Exposure periods ranged from 1 to 24 h. Cell cycle distribution (G0/G1, S, and G2/M phases) was analyzed by flow cytometry. Cell cycle analysis did not…
Metallothionein expression in ovarian cancer in relation to histopathological parameters and molecular markers of prognosis
2001
Metallothioneins (MTs) and glutathione constitute the major fractions of intracellular thiol factors. Abundant nucleophilic sulfhydryl groups can interact with many electrophilic substances, including several anti-neoplastic agents, participate in controlling intracellular redox potential, and act as scavengers of reactive oxygen species. In the present study, we examined the relation of MTs (alone and in combination with glutathione) to histopathological parameters and survival time of ovarian cancer patients. Expression of the major MT isoforms (MT-1 and MT-2) was determined by immunohistochemistry on paraffin-embedded tumor specimens from 189 patients, 151 suffering from primary epitheli…
Multivariate independent prognostic factors in endometrial carcinoma: A clinicopathologic study in 181 patients
2003
The aim of this study was to evaluate the biologic outcome of endometrial carcinomas as compared to clinical and pathologic parameters and to identify multivariate independent prognostic factors. Charts were abstracted from patients with endometrial carcinoma from 1985 to 1995. Data on clinicopathologic variables, adjuvant treatment, site of recurrence, and survival were collected. χ2 test was used to test association between variables. Kaplan-Maier method was used for survival analysis and Cox proportional hazards model for multiple regression analysis. Univariate analysis revealed that FIGO stage, tumor grade, depth of myometrial invasion, biochemical analysis of progesterone receptor sta…
