irst well defined case of the mutagenic effectiveness of chemicals was Tyet:ied for mustard gas treatment of Drosophila by AUERBACH and ROBSON ( 1946). Chemical mutagenesis studies have since been extended to a number of biological systems, including bacteria, fungi and higher organisms. AUERBACH (1965) has discussed the development of chemical mutagenesis in the last 20 years. The application ...
Sulfur mustard agent (HD) (2,2'-dichloroethyl sulfide), a Schedule I compound on the Chemical Weapons Convention Schedule of Chemicals, remains a public health concern because it is simple to synthesize and it is in the chemical weapon stockpiles of several countries. A sensitive, rapid, accurate, and precise method was developed to quantitate trace levels of 1,1'-sulfonylbis [2-(methylthio) et...
Epigenetic perturbations in the pathogenesis of mustard toxicity; hypothesis and preliminary results
Among the most readily available chemical warfare agents, sulfur mustard (SM), also known as mustard gas, has been the most widely used chemical weapon. SM causes debilitating effects that can leave an exposed individual incapacitated for days to months; therefore delayed SM toxicity is of much greater importance than its ability to cause lethality. Although not fully understood, acute toxicity...
Background: Sulfur mustard is one of the chemical warfare gases that has been known as a vesicant or blistering agents. It is a chemical alkylating compound agent that can be frequently absorbed through skin, respiratory system, genital tract, and ocular system. This study was done to pathologically analyze the microscopic pancreatic lesions in cadavers. Methods: This case series study was per...
It has been reported that the phase transitions found in the quasi-one-dimensional sulfide KCu(7-x)S4 are most likely due to vacancy ordering involving Cu+-ion diffusion along the Cu(2)-Cu(2) zigzag chains. Our previous studies with both a self-consistent method and Monte Carlo simulations confirmed that phase transitions indeed exist in a one-dimensional (1D) lattice gas system in which vacanc...
Poly(anthraquinonyl sulfide) (PAQS)/graphene sheets (GSs) composite was synthesized through in situ polymerization to evaluate its performance as an electrode material for electrochemical capacitors. PAQS was successfully synthesized in the presence of GSs with uniform distribution. PAQS/GSs showed a pair of reversible redox peaks at around 0 V (vs. Ag/AgCl). The specific capacitance of PAQS/GS...
Zirconium(IV) dilanthanum(III) penta-sulfide, ZrLa(2)S(5), crystallizes with four formula units in the space group Pnma in the U(3)S(5) structure type. The asymmetric unit comprises one Zr, one La and four S atoms. The Zr and three S atoms are situated on mirror planes. The structure consists of LaS(8) face-sharing bicapped distorted trigonal prisms and ZrS(7) edge-sharing monocapped octa-hedra.
OBJECTIVE To identify the contents of ampoules stored items at the WW I Kobarid Museum, Slovenia. Sources and methods: Analysis of ampoules from the Kobarid Museum using pharmacopoeial methods. RESULTS The contents of the unlabelled ampoules were identified as calcium hypochlorite, a decontaminant for mustard gas (Yperite). CONCLUSION The Isonzo front/Soška fronta was opened on May 24 1915 ...
A novel quaternary sulfide, Ba5Cu8In2S12 (1), has been successfully synthesized via a high-temperature solid-state reaction. It contains Cu8S10S4/2 clusters as basic building blocks, which are connected to one another by discrete In3+ ions to generate a 3D copper-rich framework, where the Ba2+ cations reside. Interestingly, such large clusters that are fused by five crystallographically indepen...
