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...

Biomedical companies catch and bleed horseshoe crabs for the production of Limulus amebocyte lysate (LAL), a product used for protecting public health (Berkson and Shuster, 1999). LAL is a clotting agent, derived solely from horseshoe crab blood cells, which is used to detect the presence of pathogenic gramnegative bacteria in injectable drugs and implantable medical and dental devices (Mikkels...

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...

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...

introduction: presently, bacteremia is the principal cause of morbidity in patients undergoing hemodialysis. gram-negative bacteria account for approximately 50 percent of documented infections. endotoxins released during lysis of gram negative bacteremia result in inflammatory and defense response by the body and if not treated promptly result in septic shock and ultimately death of the patien...

Dehydroepiandrosterone-fatty acyl esters (DHEA-FAE) belong to a unique family of naturally occurring hydrophobic steroid hormone derivatives that are transported in circulating lipoproteins and may act as a source of dehydroepiendrosterone (DHEA) and other biologically active steroid hormones in cells. Here, we studied the metabolic fate of low-density lipoprotein-associated [(3)H]DHEA-FAE ([(3...

This study investigated whether trait-like differences in brain monoaminergic functioning relate to differential vulnerability for the long-term neurochemical depletion effects of MDMA. Genetically selected aggressive (SAL) and non-aggressive (LAL) house-mice differing in baseline serotonergic and dopaminergic neurotransmission were administered MDMA. An acute binge-like MDMA injection protocol...
