1. OTIMIZAÇÃO E VALIDAÇÃO DE MÉTODO BASEADO EM QuEChERS PARA DETERMINAÇÃO DE CONSERVANTES EM COSMÉTICOS POR HPLC-DAD
Parabens are widely used as preservatives in the last decades. Others preservatives such as 2-phenoxyethanol, which in addition to his good antimicrobial activity, has low allergenic potential as well others properties of interest to the cosmetic industry. In this work was developed a method for determination of methylparaben (MP), propylparaben (PP) and 2-p

2. FIGURES OF MERIT EVALUATION OF GC/MS METHOD FOR QUANTIFICATION OF 2-PHENOXYETHANOL FROM BALLPOINT PEN INK LINES AND DETERMINATION OF THE INFLUENCE OF SUPPORT PAPER ON SOLVENT EXTRACTION
Brazilian Forensic Scientists are frequently asked about ballpoint pen manuscripts chronology in documents suspected to be forged. In the recent years, many methods like quantification of 2-PE (2-phenoxyethanol) have been developed on this subject. The validation of these methods only recently has been a concern between scientific forensic community. Researc

3. Discovery of a second geophilomorph species (Myriapoda: Chilopoda) having twenty-seven leg-bearing segments, the lowest number recorded up to the present in the centipede order Geophilomorpha
Schendylops ramirezi sp. nov. (Myriapoda: Chilopoda), a tiny schendylid centipede (from Rio de Janeiro State, Brazil), is hereby described and illustrated based on the female holotype, male and female paratypes, and additional non-type specimens. This discovery represents the second geophilomorph species characterized by having twenty-seven leg-bearing segme

4. A new dwarf species, new distribution records, and supplementary descriptive notes of the centipede genus Ityphilus Cook, 1899 (Chilopoda: Geophilomorpha: Ballophilidae) from central Amazonia, Brazil
A new dwarf species of the centipede genus Ityphilus Cook, 1899, named I. donatellae sp. nov. (Chilopoda: Geophilomorpha: Ballophilidae) is hereby proposed on the basis of specimens from the vicinity of Manaus, Central Amazonia (Brazil), previously identified as Ityphilus calinus Chamberlin, 1957 (hereby designated holotype female, paratype male and paratype

7. Padronização no uso do anestésico 2-phenoxyethanol para juvenis de matrinxã Brycon cephalus (Gunther, 1869) em procedimentos de campo
Em muitos procedimentos de campo que englobam a manipulação de peixes vivos, os animais sofrem grandes riscos de se machucarem devido aos excessivos movimentos que realizam fora da água, sendo necessária a contenção dos animais através do uso de anestésicos. O 2-phenoxyethanol é um produto químico amplamente utilizado no país, sendo, entretanto ai

8. Chlorhexidine resistance in Proteus mirabilis
A total of 104 clinical isolates of Pr. mirabilis from three hospitals were screened for their sensitivity to chlorhexidine. The minimum inhibitory concentrations of the antiseptic for these strains ranged from 10 to 800 μg/ml. Two strains sensitive to 20 μg of chlorhexidine/ml were adapted to resistance by growth in subinhibitory concentrations of the ant

9. Effect of R-plasmid RP1 and nutrient depletion on the gross cellular composition of Escherichia coli and its resistance to some uncoupling phenols.
The resistance of Escherichia coli batch cultures depleted of carbon (C-dep), magnesium (Mg-dep), or phosphate (P-dep) against low concentrations of 3-chlorophenol, 4-chlorophenol, or 2-phenoxyethanol varied. C-dep cultures were always significantly more sensitive than Mg-dep or P-dep cultures. The presence of R-plasmid RP1 increased the sensitivity of C-dep
