Adenomatous polyps are neoplasms that may progress to colorectal cancer. The role of diet and other lifestyle habits in their etiology is now being elucidated. The aim of this study was to evaluate effects of nutritional habits, weight and weight gain, tobacco smoking, and physical activity in adenoma etiology. A quantified dietary history questionnaire was(More)
Our aim was to evaluate the role of maternal nutritional habits during the period of gestation and of children subsequent diet in the etiology of pediatric brain tumors. All cases of incident nervous system tumors under age 18, diagnosed between 1984 and 1993 (n = 300) in Israel were identified. Two matched population controls per case were selected (n =(More)
Neu differentiation factor (NDF, also called heregulin) is a 44-kilodalton glycoprotein that stimulates tyrosine phosphorylation of the Neu/HER-2 receptor and induces phenotypic differentiation of certain mammary cancer cell lines to growth-arrested and milk-producing cells. To determine which molecules participate in the concomitant morphological(More)
Time course evolution of R, Q, T and ST components of the electrocardiogram during the first 12 hours of an acute myocardial infarction was studied. A comparison between anterior-extensive and anteroseptal wall infarctions (anterior group), and inferior-extensive and inferior wall infarction (inferior group) showed appearance of significant Q waves within(More)
PURPOSE Superficial bladder carcinoma, treated by resection and intravesical administration of bacillus Calmette-Guérin (BCG), yields a remission rate that approaches 70%. We examined whether expression of interleukin-2 (IL-2) or interferon-gamma (IFN-gamma) genes can serve to predict response. PATIENTS AND METHODS During BCG treatment, we analyzed(More)
A multicenter phase III randomized study compared the efficacies of two adjuvant polychemotherapeutic regimens in 145 patients with stage II node-positive breast cancer. The standard chemotherapy combination, CMF (cyclophosphamide, methotrexate, 5-fluorouracil), was administered to 77 women. The experimental protocol, CNF (cyclophosphamide, mitoxantrone,(More)

Epidemiological evidence indicates that a fair complexion and exposure to solar radiation in early years contribute to the proliferation of naevi and subsequent melanoma risk. To determine whether protection from sunlight is associated with lower naevi counts, we examined the prevalence and risk factors of naevi in a sample of Israeli school pupils. Whole(More)
AIM Environmental as well as genetic factors play a role in the pathogenesis of inflammatory bowel diseases. The effects of smoking and diet have been demonstrated. Other factors have not been extensively investigated. PATIENTS Preillness non dietary habits and factors were studied in 88 patients with recent onset of inflammatory bowel diseases (55 with(More)
Cardiopulmonary and radionuclear indices were used to evaluate and compare cardiac function during exercise testing in patients with symptomatic and silent ischemia. The study comprised 58 patients aged 35-74 years, divided into three groups: Group I-20 patients (controls) with neither ST depression nor chest pain; Group II-22 patients with ST depression >(More)
