Antibiofilm Efficacy of Peptide 1018 against Listeria
After 48 h, coupons were treated with peptide 1018 at 0, 10, 20, or 50 μg/mL in phosphate buffer saline (PBS) for 24 h. Surviving bacterial populations were determined by scraping off the coupons and spiral plating on selective media.

Sanitizing in Dry-Processing Environments Using Isopropyl
Clean stainless steel coupons and conveyor belt materials used in dry-processing environments were spot inoculated in the center of coupons (5 by 5 cm) with a six-serotype composite of Salmonella (approximately 10 log CFU/ml), subjected to IPAQuat sanitizer treatments with exposure times of 30 s, 1 min, or 5 min, and then swabbed for
Persistence and decontamination of Bacillus atrophaeus
Persistence of Bacillus atrophaeus subsp. globigii spores on corroded iron coupons in drinking water was studied using a biofilm annular reactor. Spores were inoculated at 10(6) CFU/ml in the dechlorinated reactor bulk water. The dechlorination allowed for observation of the effects of hydraulic she …
Impact of environmental conditions on the survival of
Parallel experiments were conducted using clean and soiled coupons incubated under three temperatures. The die-off coefficient rates (K) were calculated using first-order exponential formula. For both parasites, the fastest die-off was recorded on fabric, followed by ceramic, formica, skin, and steel.
Recovery and chemical disinfection of foot-and-mouth
Compare parameters off FMDV and ASFV inactivation on porous and nonporous surfaces in quantitative carrier tests of a liquid chemical disinfectant. Methods and results: Concrete test coupons were fabricated from commercial and industrial sources and carbonated by exposure to 5% CO 2 in a humidified incubator, lowering the matrix pH.
Identification of volatile degradation products from
The aim of this study was to test and develop techniques for the detection and identification of volatile compounds released as degradation products by Baltic amber. During a preliminary investigation, the off-gassing of acidic volatiles was detected through the corrosion of lead coupons. The corros …
The Effect of Disinfectants on Quinolone Resistant E. coli
Biofilm was formed on stainless steel coupons for two and five days before transferred to tubes with Virocid 0, 25%, VirkonS 1%, and TP990 1% and left for various exposure times. The biofilms were scraped off and serial dilutions were spread on blood agar …
A Supermarket Double-Dollar Incentive Program Increases
Objective: To carry out a pilot study to determine whether a supermarket double-dollar fruit and vegetable (F&V) incentive increases F&V purchases among low-income families. Design: Randomized controlled design. Purchases were tracked using a loyalty card that provided participants with a 5% discount on all purchases during a 3-month baseline period followed by the 4-month intervention.
Sildenafil citrate 100 mg starting dose in men with
Introduction: Sildenafil citrate 50 mg is the recommended starting dose for men with erectile dysfunction (ED); however, most men are later titrated to sildenafil 100 mg for improved efficacy. Aim: Assess the tolerability and efficacy of sildenafil initiated at the 100-mg dose in men with ED. Methods: Men with ED (score < or =25 on the Erectile Function domain of the International Index of
[Prescription of olanzapine in children and adolescent
Introduction: A review of the literature from 1996-2004 on the indications and adverse reactions concerning the use of olanzapine, a second generation antipsychotic agent, in children and adolescents with psychiatric illness is made in this article. Studies lasted for 2 to 3 months and a few had a follow up period up to a year. Olanzapine, dosed from 2.5 to 20 mg/day, is shown to be a useful
The effect of Sambucol, a black elderberry-based, natural
Sambucus nigra L. products - Sambucol - are based on a standardized black elderberry extract. They are natural remedies with antiviral properties, especially against different strains of influenza virus. Sambucol was shown to be effective in vitro against 10 strains of influenza virus. In a double-b …
Exposure of Glass Fiber Reinforced Polymer Composites in
An innovative testing methodology to evaluate the effect of long-term exposure to a marine environment on Glass Fiber Reinforced Polymers (GFRPs) has been investigated and is presented in this paper. Up to one-year ageing was performed in seawater, to simulate the environment for offshore oil and ga …
