Male mice, genetically selected for aggression, characterized by short attack latency (SAL) or long attack latency (LAL), differ on several testosterone (T)-related parameters during ontogeny and adult age. The variation in aggressive behavior at adult age may be due to differences in degree of androgenization prenatally. When exposed to T at prenatal, neonatal, and/or adult age, nonlactating f...
Horseshoe crabs (Limulus polyphemus) are bled by biomedical companies for the extraction of Limulus Amoebocyte Lysate (LAL), a clotting agent used in the detection of endotoxins. In 1998, the Atlantic States Marine Fisheries Conunission mandated tliat all biomedical companies collecting horseshoe crabs for the production of LAL study tl1e horseshoe crab mortality rates resulting from the compan...
Based on the biological activity of endotoxin, we propose a possible new method for detecting endotoxin using a pH-indication system of macrophage culture media. After RAW 264.7 macrophage cells were treated with lipopolysaccharide (LPS), the addition of fluorescein to the LPS-treated media reproductively reduced its absorption and emission spectra (it was a dose-dependent reduction). The advan...
Quantum dot organic solar cells (QD-OSCs) have received considerable attention because of the luminescent property QDs and good miscibility due to ligand in shell. However, use Cd- or Pb-based is limited toxicity. Hence, Zn–Cu–In–S/ZnS (ZQs) as nontoxic are used this study for light-amplification layer (LAL), consisting sub-donor (sub-D, D18-Cl) QDs. The LAL applied between hole transfer (HTL) ...
In the educational setting of Iran, language assessment literacy (LAL) is still an underexplored issue. This paper investigated the development of LAL among EFL students taking language assessment course at state universities in Iran. The three components of LAL (i.e., knowledge, skills, and principles) were the focus of the inquiry. To collect the required data, a questionnaire, encompassing 8...
As a potent inflammatory agent, endotoxin is a key analyte of interest for studies of lung ailments in domestic environments and occupational settings with organic dust. A relatively unexplored advance in endotoxin exposure assessment is the use of recombinant factor C (rFC) from the Limulus pathway in a fluorometric assay. In this study, we compared airborne endotoxin concentrations in laborat...
BACKGROUND Elevated blood endotoxin levels are frequently reported in the dialysis population and are strongly linked with inflammation, a major predictor of mortality. Virtually all studies have employed the Limulus Amoebocyte Lysate (LAL) assay to detect endotoxin. However this assay is not endotoxin-specific and can be activated by (1→3)-β-glucan (BG), a component of fungal cell walls leadin...
Acidification is acknowledged as the cause for extinction or catch reductions in numerous Atlantic salmon (Salmo salar L.) populations in Norway. In freshwater, labile (cationic/inorganic) forms of Al (LAl) accumulate in fish gills, where high concentrations result in mortality due to respiratory and ionoregulatory dysfunction. At lower concentrations, Al may still have population effects by in...
In the framework of a European contract*, LAL is in charge of the construction of one photo-injector for the drive beam linac of the CLIC Test Facility 3 [1] at CERN. This contract together with national funds allowed LAL to build a home test accelerator, PHIL, with the same photo-injector as for CTF3. The goal is to undergo experiments on the design and technology of advanced RF guns, to devel...
Unregulated cellular uptake of apolipoprotein B-containing lipoproteins in the arterial intima leads to the formation of foam cells in atherosclerosis. Lysosomal acid lipase (LAL) plays a crucial role in both lipoprotein lipid catabolism and excess lipid accumulation as it is the primary enzyme that hydrolyzes cholesteryl esters derived from both low density lipoprotein (LDL) and modified forms...
