Perfusion contrast-enhanced ultrasound to predict early lymph-node metastasis in breast cancer.

Purpose: To evaluate whether quantitative analysis of perfusion contrast-enhanced ultrasound (CE-US) could predict early lymph-node (LN) metastasis in clinically node-negative breast cancer.

Materials And Methods: In this prospective study, 64 breast cancer patients were selected for perfusion CE-US imaging. Regions of interest were placed where the strongest and weakest signal increases were found to obtain peak intensities (PIs; PI and PI, respectively) for time-intensity curve analyzes.

Prospective study on the efficacies of fondaparinux and enoxaparin in preventing venous thromboembolism after hip fracture surgery.

Background: Venous thromboembolism (VTE) is a common complication in hip fracture surgery (HFS). Fondaparinux (FPX) and enoxaparin (ENO) have been reported to decrease the incidence of VTE after HFS. The purpose of this study was to determine the efficacies of FPX and ENO and the superior agent for preventing VTE after HFS by performing a prospective study in a Japanese population.

Hepatobiliary cystadenocarcinoma with rapid growth: report of a case.

We describe a case of histologically proven hepatobiliary cystadenocarcinoma with an emphasis on the longterm clinical course. The patient was a 75-year-old man who had been diagnosed as having a simple hepatic cyst at our hospital and had been followed up by abdominal sonography (US) for about 10 years. However, the lesion subsequently showed a sudden increase in size and a marked change in US findings, i.

In vitro and in vivo analysis of the thyroid system-disrupting activities of brominated phenolic and phenol compounds in Xenopus laevis.

We investigated the effects of the brominated phenolic and phenol compounds, some of which are brominated flame retardants, on the binding of (125)I-3,3',5-L-triiodothyronine ((125)I-T(3)) to purified Xenopus laevis transthyretin (xTTR) and to the ligand-binding domain of X. laevis thyroid hormone receptor beta (xTR LBD), on the induction of a T(3)-responsive reporter gene in a recombinant X. laevis cell line (XL58-TRE-Luc) and on T(3)-induced or spontaneous metamorphosis in X.

In vitro and in vivo analysis of the thyroid disrupting activities of phenolic and phenol compounds in Xenopus laevis.

We investigated the effects of phenolic and phenol compounds on 3,3',5-L-125I-triiodothyronine (125I-T3) binding to purified Xenopus laevis transthyretin (xTTR) and to the ligand-binding domain of X. laevis thyroid hormone receptor beta (xTR LBD), on T3-induced metamorphosis in X. laevis tadpoles and on the induction of T3-dependent reporter gene in a X.
