1. Identification of reference genes for gene expression normalization in safflower (Carthamus tinctorius)
ABSTRACT Safflower (Carthamus tinctorius L., Asteraceae) is an important oil crop and medicinal plant. Gene expression analysis is gaining importance in the research of safflower. Quantitative PCR has become a powerful method for gene study. Reference genes are one of the major qualification requirements of qPCR because they can reduce the variability. To id

2. Multiple gene sequence analysis using genes of the bacterial DNA repair pathway
The ability to recognize and repair abnormal DNA structures is common to all forms of life. Physiological studies and genomic sequencing of a variety of bacterial species have identified an incredible diversity of DNA repair pathways. Despite the amount of available genes in public database, the usual method to place genomes in a taxonomic context is based m

3. Assessment of hospital daily cleaning practices using ATP bioluminescence in a developing country
Visual assessment of surfaces may not be enough to document the level of cleanliness in the hospital setting. It is necessary to introduce quantitative methods to document the results of this practice.Objective:To evaluate the efficacy of hospital terminal cleaning procedures, using an adenosine triphosphate (ATP) bioluminescence method in a teaching hospita

4. Halistanol sulfate A and rodriguesines A and B are antimicrobial and antibiofilm agents against the cariogenic bacterium Streptococcus mutans
In the present investigation we report the antibacterial activity of halistanol sulfate A isolated from the sponge Petromica ciocalyptoides, as well as of rodriguesines A and B isolated from the ascidian Didemnum sp., against the caries etiologic agent Streptococcus mutans. The transcription levels of S. mutans virulence genes gtfB, gtfC and gbpB, as well as

5. Relationship among Shigella spp. and enteroinvasive Escherichia coli (EIEC) and their differentiation
Shigellosis produces inflammatory reactions and ulceration on the intestinal epithelium followed by bloody or mucoid diarrhea. It is caused by enteroinvasive E. coli (EIEC) as well as any species of the genus Shigella, namely, S. dysenteriae, S. flexneri, S. boydii, and S. sonnei. This current species designation of Shigella does not specify genetic similari

6. Estudo de expressão transcricional no sistema nervoso central de ratos: qual gene deve ser usado como controle interno?
Objetivo Um número crescente de artigos publicados relaciona a expressão de genes específicos com diferentes padrões de comportamento em ratos. Os níveis de transcritos de ácido ribonucleico mensageiro são geralmente analisados por transcrição reversa, seguida de reação em cadeia da polimerase, e quantificados após a normalização com um contr

7. Validation of reference genes for RT-qPCR analysis of CYP4T expression in crucian carp
Reference genes are commonly used for normalization of target gene expression during RT-qPCR analysis. However, no housekeeping genes or reference genes have been identified to be stable across different tissue types or under different experimental conditions. To identify the most suitable reference genes for RT-qPCR analysis of target gene expression in the

8. Searching for convergent evolution in manganese superoxidase dismutase using hydrophobic cluster analysis
There are numerous examples of convergent evolution in nature. Major ecological adaptations such as flight, loss of limbs in vertebrates, pesticide resistance, adaptation to a parasitic way of life, etc., have all evolved more than once, as seen by their analogous functions in separate taxa. But what about protein evolution? Does the environment have a stron

9. Extended genetic analysis of Brazilian isolates of Bacillus cereus and Bacillus thuringiensis
Multiple locus sequence typing (MLST) was undertaken to extend the genetic characterization of 29 isolates of Bacillus cereus and Bacillus thuringiensis previously characterized in terms of presence/absence of sequences encoding virulence factors and via variable number tandem repeat (VNTR). Additional analysis involved polymerase chain reaction for the pres

10. Governança em higiene e limpeza hospitalar: implicações para o trabalho de enfermagem / Governance in hospital hygiene and housekeeping: implications for nursing work.
A governança na hotelaria hospitalar, atualmente, tem se mostrado como tendência. Considerando, na atualidade, a realidade dos serviços e as perspectivas sobre a implantação do serviço de governança hospitalar, voltada para a melhoria no processo de gestão, constata- se que ainda são incipientes as publicações científicas sobre a temática. A int

11. Seca de ponteiros de Eucalyptus spp. causada por Erwinia psidii no Brasil / Die-back of Eucalyptus spp. caused by Erwinia psidii in Brazil
A partir de 2009 vem sendo observada uma nova doença em eucalipto de etiologia bacteriana desconhecida, caracterizada por seca de ponteiros, murcha, lesões em ramos, pecíolo e nervura central, acompanhado de exsudação bacteriana macroscópica e microscópica. Até o presente a enfermidade já foi constatada em plantios clonais de híbridos de Eucalyptus

12. Desocupación, trabajo doméstico y desigualdad: una mirada desde el uso del tiempo en Rosario, Argentina
The changes in the work market and in the welfare systems imply a strong tension between the available resources and the existing household needs. Such inadequacy between resources and needs is compensated -in part - by an increase in unpaid housework. In this sense, this article aims to estimate the time assigned by a group of unemployed people aided by the
