OBJECTIVES This randomized, double-blind, cross-over study evaluated the risk of bronchoconstriction with two preparations of inhaled tobramycin in children with cystic fibrosis (CF) infected with Pseudomonas aeruginosa with and without airway hyperreactivity. DESIGN Of 19 children with CF (age range, 7 to 16 years) with mild-to-moderate pulmonary disease, 10 children were at high risk (HR) f...

Within a large Italian randomized trial on new technologies for cervical cancer screening involving 7 laboratories with different levels of experience, an intralaboratory and interlaboratory quality control program for human papillomavirus (HPV) DNA testing by Hybrid Capture 2 (HC2; Digene, Gaithersburg, MD) was implemented. To monitor the hybridization and detection steps, target samples conta...

We evaluated the effect of storage at 2 to 8°C on the stability of human genomic and human papillomavirus (HPV) DNA stored in BD SurePath and Hologic PreservCyt liquid-based cytology media. DNA retained the ability to be extracted and PCR amplified for more than 2.5 years in both medium types. Prior inability to detect DNA in archived specimens may have been due to failure of the extraction met...

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 nebuliser solutions has been examined...

this study was carried out to investigate the effect of differentpreservative solutions to improve the keeping quality of tuberose (polianthes tuberosa cv. single). these preservative solutions (treatments) were: t1= 2% sucrose + 200 mg/l agno3, t2= 2% sucrose + 200 mg/l agno3 + 25 mg/l citric acid, t3= 2% sucrose + 300 mg/l hqs, t4 = 2% sucrose + 300 mg/l hqs+ 25 mg/l citric acid, t5= 2% sucro...

Widely used as a wood preservative and also in many polymeric applications for protection against insects and rodents. Copper naphthenate or more specifically copper naphthenate solution which consists of 20% copper naphthenate mixed with white spirits or mineral turps type solvents have been popularly reintroduced in the market as a formulation which is effective in its primary purpose of bein...

The APTIMA HPV Assay (AHPV) allows detection of 14 high-risk human papillomavirus (HPV) RNA types in cervical specimens. Until present, the assay has been compared to HPV DNA tests only in triage settings. Herein, we compare AHPV with a DNA assay (Hybrid Capture 2; HC2) and liquid-based cytology (LBC; using PreservCyt ThinPrep liquid Pap) in a screening setting (French APTIMA screening evaluati...
