Sixty-two patients with tricuspid atresia admitted for cardiac catheterisation between 1967 and 1974 have been classified according to the anatomical and radiological findings into those with normally related great arteries (type I: 39 cases) and those with transposition of the great arteries (type II: 23 cases). These types were further subdivided into group A (reduced lung vascularity),groupB...

OBJECTIVE To evaluate the usage of duplex power Doppler ultrasound (PDUS) for the differentiation of benign and malignant thyroid nodules. MATERIALS AND METHODS We prospectively examined 77 thyroid nodules in 60 patients undergoing ultrasound-guided fine needle aspiration biopsy (FNAB). Each nodule was described according to size, inner structure, borders, parenchymal echogenicity, peripheral...

OBJECTIVE To analyze the contrast-enhancement patterns obtained at pulse-inversion harmonic imaging (PIHI) of focal hepatic lesions, and to thus determine tumor vascularity and the acoustic emission effect. MATERIALS AND METHODS We reviewed pulse-inversion images in 90 consecutive patients with focal hepatic lesions, namely hepatocellular carcinoma (HCC) (n=43), metastases (n=30), and hemangi...

Preeclampsia is a life-threatening disorder characterized by maternal gestational hypertension and proteinuria that results from placental dysfunction. Placental abnormalities include abnormal syncytiotrophoblast and a 50% reduction in placental expression of the transcription factor Gcm1. In mice, homozygous deletion of Gcm1 prevents syncytiotrophoblast differentiation and is embryonic lethal....

BACKGROUND Angiogenesis has been extensively studied in acute myeloid leukemia (AML). Lactate dehydrogenase (LDH), a common biochemical marker for tumor burden and anaerobic glycolysis, is a poor prognostic factor for AML. Regulated by hypoxia-induced factor, both vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) are responsive to cancer-related angiogenesis. T...

Current studies of tumor angiogenesis rely on the concept that endothelium proliferates 30-40 times faster in tumors than in normal tissues. This evidence is based on histological autoradiographic data largely from animal studies. To assess endothelial cell proliferation in human cancer we used the more sensitive and specific technique of immunohistochemistry. We measured the frequency and dist...

PURPOSE The aim of this study was to analyze the presence and type of vascularity with color Doppler ultrasound (CDUS) in gynecomastia, to describe gray-scale ultrasound (US) and CDUS features in different stages of gynecomastia, and to compare these findings with the characteristic US appearances of Tanner stages. MATERIALS AND METHODS A total of 108 breasts of 54 males aged 11-27 years with...

INTRODUCTION To evaluate diagnostic accuracy of high-resolution ultrasonography in differentiation of benign and malignant thyroid nodules in comparison to results of guided fine needle aspiration cytology based on the Bayes rule. OBJECTIVE To assess the validity of ultrasonography results of thyroid nodules in comparison to guided fine needle aspiration cytology findings. METHODS This stud...

OBJECTIVE The adductor muscles are implicated in the pathogenesis of groin strain, but the proximal morphology of this muscle group is poorly defined. The purpose of this study was to investigate the detailed anatomy of the entheses and proximal musculotendinous junctions (MTJs) of adductor longus (AL), adductor brevis (AB) and gracilis. METHODS The adductors were dissected bilaterally in 10 ...

Purpose: The purpose of this study is to evaluate the incidence and the degree of peritumoral edema on MRI in meningioma and to correlate other MR findings withtheedema. Materals and Methodds: MR images of 35 patients with histologically -confirmed meningioma were retrospectively reviewed. We analyzed the MR findings with special attention to the presence or absence and degree of edema. The ede...
