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.
Low-concentration hydrogen peroxide decontamination …
Decontamination evaluations were conducted in a house using both Bacillus atrophaeus var. globigii (Bg; as surrogates for B. anthracis) inoculated on the carpet and galvanized metal as coupons and Geobacillus stearothermophilus (Gs) as biological indicators on steel. The total decontamination time ranged from 4 to 7 days.
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 …
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.
Designing Incentives to Change Behaviors: Examining
On-campus students and students with more knowledge about healthy diets were more likely to increase their intent when offered coaching; students living off campus and those with less knowledge resonated with coupons. On- and off-campus students differed in their positive responses to eating fruits and vegetables versus low fat foods, respectively.
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.
A Supermarket Double-Dollar Incentive Program …
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.
N-acetylcarnosine (NAC) drops for age-related cataract
There is currently no convincing evidence that NAC reverses cataract, nor prevents progression of cataract (defined as a change in cataract appearance either for the better or for the worse). Future studies should be randomized, double-masked, placebo-controlled trials with standardised quality of l …
A five-day course of ivermectin for the treatment of …
Ivermectin, a US Food and Drug Administration-approved anti-parasitic agent, was found to inhibit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication in vitro. A randomized, double-blind, placebo-controlled trial was conducted to determine the rapidity of viral clearance and saf …
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 …
Enhanced adhesion of plasma-sprayed commercially pure
Diffusion bonding may also explain the significantly higher amounts of zirconium on the coating surface that had been pulled off the smoother lapped ceramic coupons. The measured shear strength of porous-coated ceramic coupons was significantly higher than that of CoCr and Ti-6Al-4V coupons.
Decontamination efficacy against Mycoplasma
Methods and results: Mycoplasma was dried onto stainless steel coupons and exposed to decontamination products. All strains survived drying and any significant viability loss because of the test method (including neutralization), as demonstrated by a ≤0·5 log(10) for each tested species.
Exploring Mechanisms of Recruitment and Recruitment
Respondent driven sampling (RDS) is a sampling method designed for hard-to-sample groups with strong social ties. RDS starts with a small number of arbitrarily selected participants (" seeds "). Seeds are issued recruitment coupons, which are used to recruit from their social networks. Waves of …
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 …
[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 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 …
