13. Antimicrobial and toxicological studies of some metal complexes of 4-methylpiperazine-1-carbodithioate and phenanthroline mixed ligands
A few mixed ligand transition metal carbodithioate complexes of the general formula [M(4-MPipzcdt)x(phen)y]Y (M = Mn(II), Co(II), Zn(II); 4-MPipzcdt = 4-methylpiperazine-1-carbodithioate; phen = 1,10-phenanthroline; x = 1 and y = 2 when Y = Cl; x = 2 and y = 1 when Y = nil) were synthesized and screened for their antimicrobial activity against Candida albica

14. New applications of radioguided surgery in oncology
OBJECTIVE: To report oncological cases (excluding those related to breast cancer) for which radioguided surgery has been used in combination with the Radioguided Occult Lesion Localization technique. INTRODUCTION: Radioguided surgery enables a surgeon to identify lesions or tissues that have been preoperatively marked with radioactive substances. The Radiogu

15. Echovírus 6 associado à doença exantemática
Exantema viral é considerado problema comum em regiões tropicais, afetando principalmente crianças. Diversos exantemas cutâneos estão associados a infecções por Enterovirus. Amostras biológicas provenientes de uma criança apresentando exantema generalizado foram enviadas ao Laboratório de Vírus Entéricos do Instituto Adolfo Lutz para a realizaç�

16. Survival analysis in pediatric patients with rhabdomyosarcoma: 18-year experience at the National Cancer Institute - RJ / Análise de sobrevida de pacientes pediátricos portadores de rabdomiossarcoma: 18 anos de experiência do Instituto Nacional de Câncer - RJ
INTRODUÇÃO: Rabdomiossarcoma (RMS) representa o sarcoma de partes moles mais freqüente da infância, havendo poucas informações a seu respeito em países em desenvolvimento. OBJETIVOS: Estudar o perfil demográfico, social, clínico, biológico e patológico de pacientes portadores de rabdomiossarcoma tratados em uma instituição brasileira. Estimar a

17. Rabdomiossarcoma primário de diafragma: relato de caso e revisão da literatura
Os autores relatam um caso de rabdomiossarcoma primário de diafragma, uma apresentação extremamente rara, com apenas 14 casos descritos na literatura mundial. D.K., masculino, 18 anos, apresentou 2 episódios de pneumotórax espontâneo. Tomografia computadorizada e ressonância magnética evidenciaram massa em superfície diafragmática direita; após bi

18. Primary neoplasms of the heart. Clinical and histological presentation of 50 cases
OBJECTIVE: To analyze clinical and histologic findings of 50 patients with primary neoplams of the heart in a tertiary referral center. METHODS: From 1980 to 1998, we retrospectively analyzed 50 patients, 32 of whom were females, whose ages ranged from 9 to 73 years (mean age = 44.16±18 years). RESULTS: Most tumors were located in the left side of the heart

19. Embryonal sarcoma and embryonal rhabdomyosarcoma of the orbit
A series of 34 cases of embryonal sarcoma and embryonal rhabdomyosarcoma of the orbit has been placed histologically into three groups according to their maximum degree of differentiation at any stage: (a) embryonal sarcoma, (b) non-striated embryonal rhabdomyosarcoma, and (c) striated embryonal rhabdomyosarcoma. The patients were then followed up. This pape

20. Basic fibroblast growth factor in human rhabdomyosarcoma cells: implications for the proliferation and neovascularization of myoblast-derived tumors.
Cultured human embryonal rhabdomyosarcoma cells express the basic fibroblast growth factor (bFGF) gene and they produce bFGF, which is apparently composed of two microheterogenous forms with Mrs of 16,500 and 17,200, respectively. bFGF derived from the rhabdomyosarcoma cells stimulates their own proliferation and that of human or bovine vascular endothelial

21. Comparison of beta enolase and myoglobin as histological markers of rhabdomyosarcoma.
A comparative study of beta enolase and myoglobin as markers of muscle differentiation in rhabdomyosarcoma was carried out, using an immunoperoxidase peroxidase antiperoxidase technique. Material from 26 cases of childhood rhabdomyosarcoma was studied and subdivided into embryonal and alveolar types. Positive cytoplasmic staining for beta enolase was seen in

22. Alveolar rhabdomyosarcoma presenting as subacute intravascular coagulation.
A patient with rhabdomyosarcoma is described in whom the presenting clinical and laboratory features were those of disseminated intravascular coagulation. The patient's rapid downhill course was primarily expressed by haemorrhagic tendency. An alveolar rhabdomyosarcoma, affecting many organs, including vascular and cardiac lumina, was found at necropsy and w

23. Alveolar rhabdomyosarcoma infiltrating bone marrow at presentation: the value to diagnosis of bone marrow trephine biopsy specimens.
AIMS: To describe the histological appearances of bone marrow infiltrated with rhabdomyosarcoma at presentation and to determine their value in establishing the diagnosis. METHODS: Patients presenting over seven years in the northern health region of England with rhabdomyosarcoma were studied. Bone marrow aspirates and trephine biopsy specimens taken at pres

24. Human chromosome 11 contains two different growth suppressor genes for embryonal rhabdomyosarcoma.
The identification of acquired homozygosity in human cancers implies locations of tumor suppressor genes without providing functional evidence. The localization of a defect in embryonal rhabdomyosarcomas to chromosomal region 11p15 provides one such example. In this report, we show that transfer of a normal human chromosome 11 into an embryonal rhabdomyosarc
