1. Resgate uterino em neoplasia trofoblástica gestacional de alto risco tratada com EMA-CO por embolização de artérias uterinas devido a malformações arteriovenosas
Resumo Mola hidatiforme completa (MHC) é um tipo raro de gravidez, na qual 15 a 20% dos casos podem desenvolver neoplasia trofoblástica gestacional (NTG). O diagnóstico de NTG deve ser feito o mais cedo possível, pelo monitoramento semanal do hCG sérico após esvaziamento uterino. Relatamos o caso de uma paciente primigesta, de 23 anos de idade, com MHC

2. Production of polypeptide antibiotic from Streptomyces parvulus and its antibacterial activity
A highly potent secondary metabolite producing actinomycetes strain is isolated from marine soil sediments of Visakhapatnam sea coast, Bay of Bengal. Over all ten strains are isolated from the collected soil sediments. Among the ten actinomycetes strains the broad spectrum strain RSPSN2 was selected for molecular characterization, antibiotic production and i

3. Efeitos não-genômicos dos hormônios esteróides - aldosterona e corticosterona - sobre a acidificação do túbulo proximal (S2) de ratos: estudos de microperfusão tubular e capilar, in vivo . / Nongenomic effect of steroid hormones - aldosterone and corticosterone - on acidification of rat proximal tubule (S2) studies by tubular and capillary microperfusion, in vivo .
The purpose was to determine if aldosterone and corticosterone act on the acidification of proximal tubule and if these hormonal effects are genomic and/or nongenomic. Bicarbonate reabsorption was evaluated by microperfusion. Aldosterone and corticosterone caused a significant increase in JHCO3-. In the presence of ethanol, actinomycin D, cycloheximide or es

4. Comparative quantification of umbilical cord blood CD34+ and CD34+ bright cells using the procount tm-bd and ishage protocols
The total number of CD34+ cells is the most relevant clinical parameter when selecting human umbilical cord blood (HUCB) for transplantation. The objective of the present study was to compare the two most commonly used CD34+ cell quantification methods (ISHAGE protocol and ProCount™ - BD) and analyze the CD34+ bright cells whose 7-amino actinomycin D (7AAD

5. Conexão entre os processos de degradação das reservas de proteinas e carboidratos e o edfeito dos hormonios e açucares em sementes de Sesbania virgata (Cav.) Pers / Connection between storage proteins and carbohydrates degradation and the effects of hormones and sugars in seeds of Sesbania virgata (Cav.) Pers
Seeds of Sesbania virgata (Cav.) Pers. have an endosperm which accumulates galactomannan as a storage polysaccharide in the cell walls that is hydrolysed after germination by three enzymes (a-galactosidase, endo-ß-mannanase and exo-ß-mannosidase). Besides the storage of carbon, there is a great amount of protein bodies in the cytoplasm of endospermic cells

6. Intracaval and intracardiac extension of Wilms' tumor: the influence of preoperative chemotherapy on surgical morbidity
OBJECTIVES: The aim of this retrospective study is to compare surgical complications and long-term survival in children with Wilms' tumor (WT) and tumor thrombus receiving or not preoperative chemotherapy MATERIALS AND METHODS: Review of the charts of 155 children with WT treated between 1983 and 2005, and analysis of 16/155 (10.3%) children with WT who pres

7. Utilização da actinomicina D como método de enucleação química de ovócitos bovinos destinados à transferência nuclear
Cloning by Nuclear Transfer (NT) is a low efficiency and labor intense technique. The process, in technical terms, is one of the main factors responsible for both embryo quality and quantity. Enucleation is the most aggressive step. Although alternative methods have been proposed, it remains mainly as it has been first described in the early fifties. The obj

9. Absence of peripheral blood mononuclear cells priming in hemodialysis patients
As a consequence of the proinflammatory environment occurring in dialytic patients, cytokine overproduction has been implicated in hemodialysis co-morbidity. However, there are discrepancies among the various studies that have analyzed TNF-alpha synthesis and the presence of peripheral blood mononuclear cell (PBMC) priming in this clinical setting. We measur

10. Development of a bioprocess for the production of actinomycin-D
S. parvulus was selected from three species of Streptomyces that produce actinomycins, as it has the greatest antibiotic activity (152 mg/L) and produces only actinomycin-D. Aiming at improving the antibiotic production in shaken flasks, the substitution of glucose by fructose in concentrations of 20, 30 and 40 g/L was investigated. In all cases this replace

11. Effect of actinomycin D on simian rotavirus (SA11) replication in cell culture
Rotaviruses are the major cause of viral diarrhea in humans and animals. Actinomycin D (Act D) is an antibiotic that intercalates DNA and therefore inhibits DNA-dependent transcription. The current study was carried out to assess the influence of Act D on the replication of simian rotavirus (SA11) in cell culture. Virus-infected MA-104 cell cultures were stu

12. A chemically defined medium for production of actinomycin D by Streptomyces parvulus
Um meio quimicamente definido composto de D (+) frutose, L (-) treonina, K2HPO4, MgSO4.7H2O, ZnSO4.7H2O, CaCl2.2H2O, FeSO4.7H2O e água deionizada, foi desenvolvido para maximizar a síntese de actinomicina D pelo Streptomyces parvulus DAUFPE 3124. O meio proposto resultou numa concentração antibiótica máxima de 133 mg/L enquanto que no meio inicial a pr
