The inadvertent estrogenicity of certain synthetic chemicals, and their subsequent effects on the endocrine system of humans and wildlife, is of concern. In this paper we report findings from in vitro and in vivo (uterotrophic) studies which confirm that a range of alkyl hydroxy benzoate preservatives (parabens) are weakly estrogenic. In a receptor-binding(More)
Chronic exposure of rodents to perchloroethene (PER) increased the incidence of liver tumors in male mice and resulted in a small but significant increase in the incidence of renal tumors in male rats. The tumorigenicity of PER is mediated by metabolic activation reactions. PER is metabolized by cytochrome P450 and by conjugation with glutathione.(More)
RATIONALE AND OBJECTIVES To determine the safety and pharmacokinetics of gadobenate dimeglumine in a group of subjects with moderate or severe renal impairment. METHODS The safety and pharmacokinetic profile of gadobenate dimeglumine, a gadolinium (Gd3+) chelate complex in development as a contrast agent for MRI, were evaluated in a placebo-controlled,(More)
OBJECTIVE The aim of this study was to determine prognostic factors and risk factors for recurrence in patients with Paget's disease of the vulva. METHODS The medical records of 76 patients with a diagnosis of Paget's disease of the vulva were retrospectively reviewed. The diagnosis in each case was confirmed by reviewing the pathology. Patients were then(More)
This study compares the efficacy and safety of gadoteridol with that of gadopentetate dimeglumine for enhanced MRI in subjects with intracranial lesions. A total of 92 subjects at three European centres underwent one MRI study enhanced with 0.1 mmol/kg gadoteridol and another with 0.1 mmol/kg gadopentetate dimeglumine. Contrast agents were assigned in(More)
Gadoteridol injection is a low molecular weight chelate complex of gadolinium (III) which is useful as a contrast agent for magnetic resonance imaging. A total of 2481 adult and pediatric subjects were studied with gadoteridol at doses from 0.025 to 0.3 mmol/kg in phase I–IIIb clinical trials in Europe and the United States. The study population had a mean(More)
A non-invasive Doppler ultrasound technique is described for the assessment of aortic compliance based on the in vivo measurement of pulse wave velocity along the thoraco-abdominal aortic pathway. A structured protocol, which has been developed to improve the reproducibility of the technique, is validated. A method of correcting for the effect of(More)
A non-invasive Doppler ultrasound technique for the assessment of aortic compliance based on the in vivo measurement of pulse wave velocity along the thoraco-abdominal aortic pathway is described. An approach for correcting for the effect of blood pressure on aortic compliance is considered. The derivation of an index of distensibility, Cp, which is(More)
BACKGROUND Extragonadal endodermal sinus tumors arising in the external genitalia represent an exceedingly rare malignancy in women. Six cases of endodermal sinus tumors of the vulva have been reported to date, with three cases failing to respond to conservative surgery and vincristine-based chemotherapy. We report a seventh case of vulvar endodermal sinus(More)
