Untersuchung des Epsilon-Toxins und Mutanten des Epsilon-Toxins aus Clostridium perfringens auf Kanalbildung
… der Bindekomponente des Epsilon-Toxins und der Epsilon-Toxin-Mutanten mit Hilfe künstlicher Lipid-Bilayer-Messungen. Es galt herauszufinden, welcher Teil des Epsilon-Toxins für die Kanalbildung verantwortlich ist, um somit die kanalbildende Domäne definieren zu können. Um diese …

Clostridium difficile and its toxins
An investigation of Clostridium difficile has shown : 1. that the organism is resistant to cresols and phenolq and may be grown from material grossly contaminated with other organisms by culture in media containing these substances; strains isolated before this method was evised are also resistant …

Cellular interactions of the cytolethal distending toxins
… system, pathogenic effector proteins, called toxins, have exploited existing pathways as a mean to access intracellular targets and modulate host cellular functions. Among known targets in the human host, nucleus has been an infrequent, covert, and a coveted target, and very few external …

Purification and characterization of Clostridium sordellii toxins HT and LT and comparison to toxins A and B of Clostridium difficile
… It is now known that C. difficile produces two toxins, designated A and B, that are implicated in the pathogenesis of the disease. C. sordellii produces two toxins, designated HT (Hemorrhagic Toxin) and LT (Lethal Toxin), that are similar to toxins A and B of C. difficile. The goal of my …

Purification, detection and biological effects of cyanobacterial toxins.
… threat to water quality as many species produce toxins. These toxins have been implicated in the poisoning of humans and animals throughout the world, and there is a requirement for simple and effective methods for their detection. This study set out to investigate the detection of several …

STRUCTURE, FUNCTION AND FOLDING OF THREE FINGER TOXINS
Three finger toxins (3FTxs) are one of the family of peptides in snake venom. Despite the common protein fold, they exhibit diverse pharmacological activities. Our group characterized Oh9-1, a neurotoxin from venom of Ophiophagus hannah. Although Oh9-1 binds to the same acetylcholine binding pocket …

Isolation and characterisation of toxins from Fibrocapsa japonica (Raphidophyceae)
… unclear. Although some views of fibrocapsins (toxins produced by this alga) were ever reported e.g. brevetoxins, but not acceptable for lack of conclusiveness. In this work, the toxicity of Fibrocapsa japonica algal cells was first established by Artemia salina biotest. Fibrocapsins was …

Investigations of microcystins (cyanobacterial peptide toxins) detection, purification and analysis.
… of microcystins, the cyclic heptapeptide toxins produced by cyanobacteria. The method of detection relied on high performance liquid chromatography (HPLC) analysis which led to the development of large-scale purification processes to provide material for use as standards in routine …

Environmental Toxins and Essential Trace Elements at Delivery and ADHD
Perfluorinated compounds (PFCs), phthalates, manganese and selenium are ubiquitous in the environment and humans and influence fetal growth and development. Register and biobank based case-control studies were conducted to investigate the relationship between prenatal exposure to these chemicals …

Role of Pyrenophora teres toxins in net blotch of barley.
… isolated in this study are host specific phytotoxins. This research has allowed the first isolation of proteinaceous host-specific toxins from P. teres as well as the identification of a UV-sensitive LMWC phytotoxin not previously described. Proteinaceous toxins induced brown necrotic …

Toxins and Toxicity from the Cosmopolitan, Bloom-Forming Dinoflagellate Karlodinium micrum
… USA. As part of that investigation we described toxins in this species for the first time. Named karlotoxins (KmTx), these compounds possess hemolytic, cytotoxic, and anti-fungal properties. However, the primary harmful effect associated with blooms of this organism is ichthyotoxicity. …

Ionic Liquids Tethered to Activated Carbon for Capture of Airborne Toxins
… (AC) adsorbents for the filtration of warfare toxins. Preliminary steps were taken by testing absorption capacity of neat ILs and tethering ionic liquids to the surface of AC. AC is known to have good adsorption ability for warfare agents. Functionalizing the AC with ILs could enhance the …

Effects of hydrothermal liquefaction on algal toxins from harmful algae blooms
… risks to the environment due in part to the toxins they release. A promising mitigation technique is to physically collect the HABs from the environment and convert them into biofuel via hydrothermal liquefaction (HTL). A large coproduct of the HTL process is the aqueous product (HTLaq), …

Evaluating the Source-Effect Relationship of Industrial Toxins in Wastewater Treatment
Upset events due to the inflow of toxic chemicals are a critical issue for wastewater treatment facilities. Understanding the source-effect relationship of toxic chemicals can facilitate the prevention or improved reaction to upset events. Part one of this study was conducted to investigate the …
