The influence of sublethal concentrations of two sanitizers, liquid iodophor and liquid hypochlorite (LH), on the growth rates and toxicity of food-borne pathogenic Escherichia coli strains grown in the presence of spoilage yeast Zygosaccharomyces bailii was assessed. When grown in combination with Z. bailii both E. coli O113 and E. coli O26 exhibited slower growth rates, except when E. coli O1...

To assay lipopolysaccharides (LPSs) in solutions containing Limulus amebocyte lysate (LAL)-inhibiting or LAL-enhancing compounds, we developed a selective endotoxin (LPS) assay using poly(epsilon-lysine)-immobilized cellulose beads (PL-Cellufine) and LAL. The PL-Cellufine can adsorb LPSs in a solution containing certain compounds (NaCl, proteins and amino acids) at an ionic strength of mu = 0.0...

Therefore, improving teachers’ language assessment literacy (LAL) is one of the most important factors in assuring quality testing and (LTA). Thus, this study aimed to investigate perceived level LAL among Saudi in-service English as a foreign (EFL) teachers. Additionally, it identify aspects that EFL teachers wish improve through further professional training. Two research questions were formu...

Abstract For pre-service teacher education, it would be helpful to know how difficult certain aspects of language testing and assessment are for students. Such information could serve different pedagogical purposes including program design lesson sequencing. This paper, situated in the context education at University Vienna, Austria, presents an approach developing literacy (LAL) which takes ac...

BACKGROUND As reported elsewhere, there are several drawbacks associated with traditional liposuction: increased blood loss, ecchymoses, long recovery times with increased postoperative discomfort, and skin laxity. Laser-assisted lipolysis (LAL) is an emerging technology, but the level of safety associated with this device has not been reported. In October 2006, a 1064-nm Nd:YAG laser was appro...

To characterize individual differences in neuroendocrine and neurochemical correlates of stress coping, two lines of wild house mice were studied. These mice are genetically selected for high and low aggression and show distinctly different behavioral strategies toward environmental stimuli. Long attack latency (LAL), low aggressive mice display a passive coping style, whereas short attack late...

methods mycobacterium tuberculosis standard strain crbip7.11 was cultured at 37°c in loewenstein johnson (lj) media for 3-4 weeks. to confirm the species, standard microbiological and biochemical tests were performed. after preparation of membrane vesicles, the amount of protein in membrane vesicles was measured by sds-page and nanodrop. to analyze the integrity and morphology of extracellular ...

Dr. Joseph Chen first presented Low Endotoxin Recovery (LER) in April 2013.1 A masking effect of endotoxin was observed with a matrix containing a chelating agent and a detergent, and the endotoxin potency was not successfully recovered by dilution or magnesium replacement, the usual way to overcome the inhibition caused by chelation. The LER brought us some concerns relating to the suitability...
