The Limulus test in experimental and clinical endotoxaemia
Journal of British Surgery, 1974 Abstract Gram-negative septicaemia is being recognized (is an increasingly common cause of mortality in hospital practice. In this paper the value of a simple and rapid test which can be used to detect the presence of circulating endotoxins is assessed in experimental and clinical situations.

Validation of moist and dry heat processes used for sterilization and depyrogenation during ampoules manufacturing [PDF]
Journal of Advanced Biomedical and Pharmaceutical Sciences, 2020 Pyrogens are fever-producing substances, which are metabolic products of microorganisms and most potent pyrogens are the endotoxins. Depyrogenation can be defined as the elimination of all pyrogenic substances which is an important part of the ...

An expert review on current approaches for endotoxin detection in various biological products
Archives of Pharmaceutical Sciences Ain Shams University, 2019 Endotoxin is heat-stable lip polysaccharide (LPS) present in the outer membrane of the cell wall of Gram-negative bacteria. All parenteral preparations, as well as tissue implants, must be with no pyrogenic level of endotoxin or other related materials ...

Improvement of the Micromethod for the Limulus Lysate Test [PDF]
Microbiology and Immunology, 1978 AbstractFrauch's micro‐slide method was improved to facilitate the endpoint‐determination of the Limulus test. Two precise observations, by inverted phase contrast microscopy and with a staining procedure, were newly performed as additions to the slide test.

Measurement of endotoxins with the limulus test in burned patients [PDF]
Journal of Hygiene, 1979 SUMMARYHigh titres of endotoxin as measured by the Limulus test were usually found in burned patients who had raised body temperatures, and were colonized with gram-negative bacteria; also some infected patients showed raised endotoxin without a raised temperature.Patients vaccinated with an antipseudomonas vaccine rarely showed endotoxin in their ...

Allergy, EarlyView.Exposure to 305 nm PP NPs significantly disrupts the airway barrier‐on‐chip, reducing TEER, suppressing ZO‐1/ACE2 expression, and triggering ROS‐mediated apoptosis. In biological media, PP NPs exhibit a biphasic adsorption pattern, leading to the formation of a protein corona that increases their size to 364 nm.
