this study constitutes an attempt to see what language assessment literacy (lal) isfor three groups of stakeholders, namely lal test developers, lal instructors, andlal test-takers. the perceptions of the former group were derived from the contentanalysis of the latest version of the lal test, and those of the latter 2 groups wereassessed through a survey designed by the researcher. participant...

The possibility of replacing the rabbit pyrogen test by the Limulus Amebocyte lysate (LAL) test, as a final release test for Large Volume Parenterals (LVPs) was investigated. The sensitivity and specificity of the LAL test and rabbit pyrogen assay were studied by means of artificially contaminated parenterals. Various LVPs (mostly containing electrolytes) were spiked with 0.5 and 5 EUlml o...

haemorrhagic septicaemia (hs) vaccine which is prepared in razi institute is used in endemic areas ofiran. aluminum-hydroxide gel was used as adjuvant for preparing this vaccine. post-vaccinal shock reactionswere the main complaint after use of this vaccine. in a previous study, we could improve the vaccine byalum-precipitation pasteurella multocida cells and removing the liquid phase. in this ...

The Limulus amoebocyte lysate (LAL) test was evaluated for rapid detection of gram-negative bacteriuria in an adult patient population. Time to gelation of a standard LAL preparation was used as a measure of significant (greater than 10(5) bacteria per ml) gram-negative bacteriuria, and the results of 190 LAL assays were compared with quantitative urine cultures. Initially, 33 of 36 urine speci...

This year celebrates the 30th anniversary of the licensing of Limulus amebocyte lysate (LAL) by the US Food and Drug Administration (FDA) as a test for the presence of endotoxin in biologicals, pharmaceutical drugs, and medical devices. LAL is currently recognized by several major pharmacopoeias and is used worldwide. That a suitable alternative for the detection of endotoxin has not supplanted...

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...

On June 22, 2011, the U.S. Food and Drug Administration (FDA) withdrew the “Guideline on Validation of the Limulus Amebocyte Lysate Test as an End-product Test for Human and Animal Parenteral Drugs, Biological Products, and Medical Devices,” which was issued in 1987. Elements of the Guideline continue to impact current methods because they can be found in other references relied on by the indus...
