Este trabalho estuda o fluxo de etileno glicol (MEG) sobre duas superfícies sólidas com constituições químicas diferentes: borossilicato e dióxido de estanho (SnO2). O alinhamento intermolecular, determinado como polarização e anisotropia, mostrou dependência da natureza química do sólido. A razão entre as tensões interfaciais dinâmicas foi 1.09 ± 0.07, devendo ser maior para MEG/borossilicato ...

Microdensitometric measurement of the DNA content of individual megakaryocytes was performed using megakaryocyte colonies obtained following culture, in soft agar, of hematopoietic cells from C57BL/6J mice. Two types of colonies were detected. After 7 days of culture, the big cell type contained 16 /+- 2.3 acetylcholinesterase (AChE) positive cells/colony, with a mean ploidy level of 16.8 /+- 0...

The purpose of this study was to develop a stair-climbing test to measure energy cost (EC) and mechanical efficiency (ME) in children with cerebral palsy (CP) to evaluate ambulation-related motor function and its changes after intervention or maturation. Five normally developed (ND) and 10 children with CP were tested. The gross ME (MEg) was calculated from the work done (W) and the total energ...

OBJECTIVE We sought to review the status of patients with breast cancer who were treated with estrogen replacement therapy and compare the results with those of nonestrogenic hormone users and women not treated with hormone replacement. STUDY DESIGN The study group consisted of 76 patients with breast cancer, including 50 using estrogen replacement for up to 32 years, 8 using nonestrogenic ho...

OBJECTIVE To determine the effect of protease inhibitors (PIs) on growth and body composition in children with human immunodeficiency virus type 1 (HIV-1) infection. BACKGROUND HIV-1-infected children have chronic problems with both linear growth and weight gain. Viral load may directly influence growth and nutritional status of HIV-1-infected children with reduction of viral load improving t...

Breast and prostate cancers are the most common malignant disease in female and male world population, respectively. Both of these tumors are predominantly hormonal-dependent, what is rationale for the widely used endocrine treatment, with specific approach in each of them. Although endocrine treatment is obviously effective and responsible for prolonged progression-free survival and even survi...
