3. Post-harvest of safflower flower stems harvested at different times and submitted to different preservative solutions
Resumo A conservação das hastes florais cortadas tem como finalidade prolongar a durabilidade, manter a qualidade e reduzir as perdas após a colheita, propiciando um período maior de vida útil e comercialização. Assim, o objetivo deste trabalho foi avaliar a qualidade e a durabilidade na pós-colheita de hastes florais frescas de cártamo (Carthamus t

4. Avaliação de proteção celular a isquemia de retalhos musculares com soluções preservadoras de tecidos em modelo de ratos / Avaliação de proteção celular à isquemia de retalhos musculares com soluções preservadoras de tecidos em modelo de ratos
The free flaps transfer and reimplantation of tissue has in common the exposure of the tissue to ischemia and different time of reperfusion which are important for the determination of the extent of the cellular injury, being sometimes irreversible. In the pre and trans-surgical procedure the control of the ischemic period is difficult. Although efforts are

7. Eficiência de inseticidas para preservar madeira contra danos de cupim subterrâneo / Efficiency of insecticides to preserve wood against damages of subterranean termite
A field test was developed to evaluate the efficiency of three insecticides as wood preservatives against damages caused by the subterranean termite Coptotermes havilandi Holmgren, 1911 (Isoptera: Rhinotermitidae). The commercial products with their respective appraised active ingredients were: Dursban 4E chlorpyrifos; Diazinon 60 EC diazinon and Dragnet 384

8. Comparison of the efficacy of preservative free ipratropium bromide and Atrovent nebuliser solution.
The paradoxical bronchoconstriction observed with commercially available isotonic ipratropium bromide nebuliser solution (Atrovent) in patients with asthma results from an adverse reaction to the preservatives, benzalkonium chloride and ethylenediaminetetra-acetic acid (EDTA). The airway response to inhaled Atrovent and preservative free ipratropium bromide

9. Electrochemical Ag+ for preservative use.
In contact experiments with different experimental conditions, electrochemical Ag+ solutions exhibited better antimicrobial effectiveness against bacteria, a yeast species, and a mold than did analogous silver solutions from inorganic salts. The particular characteristics of electrochemical Ag+, such as the mode of action, effectiveness at low concentrations

10. Association of Pseudomonas and Serratia corneal ulcers with use of contaminated solutions.
The wetting and soaking solutions and contact lens cases of eye clinic patients commonly were contaminated with gram-negative bacteria during their use. Serratia marcescens occurred most frequently in preserved solutions, whereas Pseudomonas aeruginosa was most often recovered from home-prepared saline. The bacteria were recovered at densities of greater tha

11. The wood preservative chromated copper arsenate is a substrate for trimethylarsine biosynthesis.
The wood preservative chromated copper arsenate (CCA) is a very widely used product. As it contains both copper and arsenic, it is not dissimilar to the pigments Scheele's green and Schweinfurter's green which were found to be biologically convertible to the toxic Gosio gas (B. Gosio, Ber. 30:1024-1026, 1897) later identified by Challenger and co-workers as

12. Effect of preservative on the efficacy of terbutaline nebuliser solution in atopic asthma.
The efficacy of bronchodilator nebuliser solutions may be influenced by the presence of preservatives. In a double blind, randomised, crossover study the effect of preservatives in determining the airway responses to 5 mg of terbutaline was studied in a group of 21 atopic asthmatic patients. The presence of preservatives affected neither the bronchodilator a
