The Chemical Weapons Convention prohibits the development, production, acquisition, stockpiling, retention, transfer or use of chemical weapons by Member States. Verification of compliance and investigations into allegations of use require accurate detection of chemical warfare agents (CWAs) and their degradation products. Detection of CWAs such as organophosphorus nerve agents in the environme...

Current oxime therapies do not readily cross the blood-brain barrier to reactivate organophosphorus nerve agent-inhibited cholinesterase (ChE) within the CNS. We investigated the ability of monoisonitrosoacetone (MINA), a tertiary oxime, to reactivate ChE inhibited by the nerve agent sarin (GB), cyclosarin (GF), or VX, in peripheral tissues and brain of guinea pigs and determined whether reacti...

The inorganic elements potentially migrating from cork to a food simulant [a hydroalcoholic solution containing 12 and 20% (v/v) ethanol] have been determined by means of inductively coupled plasma (ICP) with atomic emission and mass spectrometric detection. The experimental instrumental conditions were evaluated in depth, taking into account spectroscopic and nonspectroscopic interference caus...

in the present study, tenorite (cuo) nanoparticles have been assayed for their catalytic properties. the decontamination reaction of chloro ethyl ethyl sulfide (cees) as an surrogate of sulfur mustard simulant have been accomplished on the surface of cuo nps with different weight ratios at ambient temperature and monitored by gas chromatography equipped with flame ionization detector (gc-fid) a...

Nerve tissue damage as a result of surgical injury is common negative outcome during many interventions. Depending on the site and amount cellular damage, nerve may potentially have life altering effect patient. Post-surgical pain often chronic problem which persists long after injuries healed, can severely infringe upon quality for individuals. Surgery that fluorescence guided will aid in visu...

Nerve agents that irreversibly deactivate the enzyme acetylcholinesterase are extremely toxic weapons of mass destruction. Thus, developing methods to detect these lethal is important. To create an optical sensor for a surrogate nerve agent tabun, as well physical barrier dissolves in response this analyte, we devise network hydrogel decomposes via self-propagating cascade. A Meldrums acid-deri...

Peripheral nerve long gap defects are a clinical challenge in the regeneration field. Despite the wide variety of surgical techniques and therapies, autografting is the "gold standard" for peripheral nerve gap reconstruction. The pathological process of Wallerian degeneration from the time of acute injury to efficient regeneration requires several weeks. Regeneration time is critical for nerve ...

The aims of this project were to structurally study and bioengineer thermostable prolidases from Pyrococcus furiosus (Pf) and horikoshii (Ph) to enable their use for oganophosphorus nerve agent detoxification. Pf prolidase contains one dinuclear Co metal-center/monomer and has optimal activity at 100?C, exhibiting no activity without Co2+ or at temperatures <50?C. Requirement for metal ions is ...
