1. Controle interno da qualidade dos exames citológicos do colo do útero: pré-escrutínio rápido versus revisão rápida de 100% / Internal quality control of the cervical cytologic exams:Rapid prescreenig versus 100% rapid review
As altas taxas de resultados falso-negativos são problemas enfrentados na rotina dos laboratórios de citopatologia. Dentre os métodos de controle interno da qualidade, a revisão de 10% é a menos eficiente para detectar os resultados falso-negativos do escrutínio de rotina. No entanto, há evidências de que a revisão rápida de 100% e o pré-escrutín

3. Eficiência do pré-escrutínio rápido, revisão aleatória de 10% e critérios clínicos de risco como métodos de controle interno da qualidade dos exames citopatológicos cervicais / Efficiency of rapid prescreening, 10% random review and review based on clinical risk criteria as methods of internal quality control of cervical smear testing
Cytopathology is an effective method of screening for cervical cancer; however, this method has high rates of false-negative results (FNR). To reduce FNR, routine measures of internal and external quality control are required in laboratories. The 10% random review of negative smears (R-10%) is the most commonly used method; however, it is not effective in re

O exame citopatológico é um método eficiente para prevenir o câncer do colo do útero, no entanto, apresenta altas taxas de resultados falso-negativos (RFN). Para reduzir os RFN, são necessárias medidas de controle interno e externo da qualidade na rotina dos laboratórios. O método de revisão aleatória de 10% dos esfregaços negativos (R-10%) é o

7. Use of covalently closed circular deoxyribonucleic acid for prescreening for antitumor compounds.
The interactions of PM-2 deoxyribonucleic acid (DNA) with 20 known antineoplastic agents were studied using agarose gel electrophoresis and fluorescence assay systems. Actinomycin D and adriamycin (and all other anthracyclines studied) induced superhelical conformational changes in PM-2 DNA. Bleomycin A2, tallysomycin, neocarzinostatin, macromomycin, and hed

8. Rapid review (partial rescreening) of cervical cytology. Four years experience and quality assurance implications.
AIMS: To determine the sensitivity of the partial rescreening method of rapid review for internal quality control of cervical cytology; to determine which staff members are most suited to undertake it; and to investigate the cell patterns of false negative smears previously detected by the method. METHODS: As a prospective study 9517 cervical smears were par

9. Identification of combinatorial drug regimens for treatment of Huntington's disease using Drosophila
We explore the hypothesis that pathology of Huntington's disease involves multiple cellular mechanisms whose contributions to disease are incrementally additive or synergistic. We provide evidence that the photoreceptor neuron degeneration seen in flies expressing mutant human huntingtin correlates with widespread degenerative events in the Drosophila CNS. W

10. Mutagenicity and toxicity of carcinogenic and other hydrazine derivatives: correlation between toxic potency in animals and toxic potency in Salmonella typhimurium TA1538.
Eleven hydrazine derivatives and an aromatic amine were examined for mutagenicity and toxicity to Salmonella typhimurium. Phenylhydrazine, 2-nitrophenylhydrazine, 4-nitrophenylhydrazine, 2,4-dinitrophenylhydrazine, p-tolylhydrazine, and 4-nitroaniline were found to be frameshift mutagens (strain TA1538). Benzylhydrazine, m-hydroxybenzylhydrazine, p-hydrazino

11. Rapid detection of human papillomavirus in cervical scrapes by combined general primer-mediated and type-specific polymerase chain reaction.
A two-step polymerase chain reaction (PCR) procedure was used as a new screening strategy for the detection of human papillomavirus (HPV) genotypes in cervical scrapes omitting prior DNA extraction. Sample preparation consisted of a freeze-thaw step followed by boiling the cells before the PCR mixture was added. This pretreatment was as efficient and reprodu

12. Bacterial Cell Surface Display of Organophosphorus Hydrolase for Selective Screening of Improved Hydrolysis of Organophosphate Nerve Agents
Organophosphorus hydrolase (OPH) is a bacterial enzyme that has been shown to degrade a wide range of neurotoxic organophosphate nerve agents. However, the effectiveness of degradation varies dramatically, ranging from highly efficient with paraoxon to relatively slow with methyl parathion. Sequential cycles of DNA shuffling and screening were used to fine-t
