High frequency of codon 61 K-ras A-->T transversions in lung and Harderian gland neoplasms of B6C3F1 mice exposed to chloroprene (2-chloro-1,3-butadiene) for 2 years, and comparisons with the structurally related chemicals isoprene and 1,3-butadiene. (1/9)

Chloroprene is the 2-chloro analog of 1,3-butadiene, a potent carcinogen in laboratory animals. Following 2 years of inhalation exposure to 12.8, 32 or 80 p.p.m. chloroprene, increased incidences of lung and Harderian gland (HG) neoplasms were observed in B6C3F1 mice at all exposure concentrations. The present study was designed to characterize genetic alterations in the K- and H-ras proto-oncogenes in chloroprene-induced lung and HG neoplasms. K-ras mutations were detected in 80% of chloroprene-induced lung neoplasms (37/46) compared with only 30% in spontaneous lung neoplasms (25/82). Both K- and H-ras codon 61 A-->T transversions were identified in 100% of HG neoplasms (27/27) compared with a frequency of 56% (15/27) in spontaneous HG neoplasms. The predominant mutation in chloroprene-induced lung and HG neoplasms was an A-->T transversion at K-ras codon 61. This mutation has not been detected in spontaneous lung tumors of B6C3F1 mice and was identified in only 7% of spontaneous HG neoplasms. In lung neoplasms, greater percentages (80 and 71%) of A-->T transversions were observed at the lower exposures (12.8 and 32 p.p.m.), respectively, compared with 18% at the high exposure. In HG neoplasms, the percentage of A-->T transversions was the same at all exposure concentrations. The chloroprene-induced ras mutation spectra was similar to that seen with isoprene, where the predominant base change was an A-->T transversion at K-ras codon 61. This differed from 1,3-butadiene, where K-ras codon 13 G-->C transitions and H-ras codon 61 A-->G transitions were the predominant mutations. The major finding of K-ras A-->T transversions in lung and Harderian gland neoplasms suggests that this mutation may be important for tumor induction by this class of carcinogens.  (+info)

Multiple organ carcinogenicity of inhaled chloroprene (2-chloro-1,3-butadiene) in F344/N rats and B6C3F1 mice and comparison of dose-response with 1,3-butadiene in mice. (2/9)

Chloroprene (2-chloro-1,3-butadiene) is a high production chemical used almost exclusively in the production of polychloroprene (neoprene) elastomer. Because of its structural similarity to 1,3-butadiene, a trans-species carcinogen, inhalation studies were performed with chloroprene to evaluate its carcinogenic potential in rats and mice. Groups of 50 male and female F344/N rats and 50 male and female B6C3F1 mice were exposed to 0, 12.8, 32 or 80 p.p.m. chloroprene (6 h/day, 5 days/week) for 2 years. Under these conditions, chloroprene was carcinogenic to the oral cavity, thyroid gland, lung, kidney and mammary gland of rats, and to the lung, circulatory system (hemangiomas and hemangiosarcomas), Harderian gland, kidney, forestomach, liver, mammary gland, skin, mesentery and Zymbal's gland of mice. Survival adjusted tumor rates in mice were fit to a Weibull model for estimation of the shape of the dose-response curves, estimation of ED10 values (the estimated exposure concentration associated with an increased cancer risk of 10%) and comparison of these parameters with those for 1,3-butadiene. Butadiene has been identified as a potent carcinogen in mice and has been associated with increased risk of lymphatic and hematopoietic cancer in exposed workers. Shape parameter values for most of the neoplastic effects of chloroprene and 1,3-butadiene were consistent with linear or supralinear responses in the area near the lowest tested exposures. The most potent carcinogenic effect of 1,3-butadiene was the induction of lung neoplasms in female mice, which had an ED10 value of 0.3 p.p.m. Since the ED10 value for that same response in chloroprene exposed mice was also 0.3 p.p.m., we conclude that the carcinogenic potency of chloroprene in mice is similar to that of 1,3-butadiene. Cancer potency of chloroprene is greater in the mouse lung than in the rat lung, but greater in the rat kidney than in the mouse kidney and nearly equivalent in the mammary gland of each species.  (+info)

Kinetic modeling of beta-chloroprene metabolism: II. The application of physiologically based modeling for cancer dose response analysis. (3/9)

beta-Chloroprene (2-chloro-1,3-butadiene; CD), which is used in the synthesis of polychloroprene, caused significant incidences of several tumor types in B6C3F1 mice and Fischer rats, but not in Wistar rats or Syrian hamsters. This project investigates the relevance of the bioassay lung tumor findings to human health risk by developing a physiologically based toxicokinetic (PBTK) model and exploring a tissue specific exposure-dose-response relationship. Key steps included identification of the plausible genotoxic mode of action, experimental quantification of tissue-to-air partition coefficients, scaling of in vitro parameters of CD metabolism for input into the PBTK model, comparing the model with in vivo experimental gas uptake data, selecting an appropriate tissue dosimetric, and predicting a corresponding human exposure concentration. The total daily milligram amount of CD metabolized per gram of lung was compared with the animal bioassay response data, specifically combined bronchiolar adenoma/carcinoma. The faster rate of metabolism in mouse lung agreed with the markedly greater incidence of lung tumors compared with the other rodent species. A lung tissue dose was predicted for the combined rodent lung tumor bioassay data at a 10% benchmark response. A human version of the PBTK model predicted that the lung tissue dose in humans would be equivalent to continuous lifetime daily exposure of 23 ppm CD. PBTK model sensitivity analysis indicated greater dependence of model predictions of dosimetry on physiological than biochemical parameters. The combined analysis of lung tumor response across species using the PBTK-derived internal dose provides an improved alternative to default pharmacokinetic interspecies adjustments for application to human health risk assessment.  (+info)

Kinetic modeling of beta-chloroprene metabolism: I. In vitro rates in liver and lung tissue fractions from mice, rats, hamsters, and humans. (4/9)

Beta-chloroprene (2-chloro-1,3-butadiene, CD) is carcinogenic by inhalation exposure to B6C3F1 mice and Fischer F344 rats but not to Wistar rats or Syrian hamsters. The initial step in metabolism is oxidation, forming a stable epoxide (1-chloroethenyl)oxirane (1-CEO), a genotoxicant that might be involved in rodent tumorigenicity. This study investigated the species-dependent in vitro kinetics of CD oxidation and subsequent 1-CEO metabolism by microsomal epoxide hydrolase and cytosolic glutathione S-transferases in liver and lung, tissues that are prone to tumor induction. Estimates for Vmax and Km for cytochrome P450-dependent oxidation of CD in liver microsomes ranged from 0.068 to 0.29 micromol/h/mg protein and 0.53 to 1.33 microM, respectively. Oxidation (Vmax/Km) of CD in liver was slightly faster in the mouse and hamster than in rats or humans. In lung microsomes, Vmax/Km was much greater for mice compared with the other species. The Vmax and Km estimates for microsomal epoxide hydrolase activity toward 1-CEO ranged from 0.11 to 3.66 micromol/h/mg protein and 20.9 to 187.6 microM, respectively, across tissues and species. Hydrolysis (Vmax/Km) of 1-CEO in liver and lung microsomes was faster for the human and hamster than for rat or mouse. The Vmax/Km in liver was 3 to 11 times greater than in lung. 1-CEO formation from CD was measured in liver microsomes and was estimated to be 2-5% of the total CD oxidation. Glutathione S-transferase-mediated metabolism of 1-CEO in cytosolic tissue fractions was described as a pseudo-second order reaction; rates were 0.0016-0.0068/h/mg cytosolic protein in liver and 0.00056-0.0022 h/mg in lung. The observed differences in metabolism are relevant to understanding species differences in sensitivity to CD-induced liver and lung tumorigenicity.  (+info)

Influence of shooting angle of polishing particle on surface roughness of a cobalt-chromium alloy using a centrifugal shooting type polishing machine. (5/9)

The centrifugal shooting type polishing machine is a recently developed apparatus that seeks to improve the efficiency and environment of polishing removable prostheses. In an attempt to optimize the effectiveness of this apparatus, this study examined the influence of the shooting angle of polishing particle on the surface roughness of cobalt-chromium alloy casting specimens. Polishing was performed for three minutes under five shooting angle conditions: 90 degrees, 60 degrees, 45 degrees, 30 degrees, and 15 degrees. Surface roughness (Ra, Sm) was measured after each polishing stage. There were significant differences (p < 0.01) in Ra between shooting angle of 90 degrees (0.95 microm) and shooting angles of 45 degrees (0.62 microm) or less, and in Sm between 90 degrees (207 microm), 60 degrees (350 microm), and shooting angles of 45 degrees (868 microm) or less. These findings indicated that excellent surface texture was produced when shooting angle was 45 degrees or less.  (+info)

Evaluation of an artificial intelligence program for estimating occupational exposures. (6/9)

Estimation and Assessment of Substance Exposure (EASE) is an artificial intelligence program developed by UK's Health and Safety Executive to assess exposure. EASE computes estimated airborne concentrations based on a substance's vapor pressure and the types of controls in the work area. Though EASE is intended only to make broad predictions of exposure from occupational environments, some occupational hygienists might attempt to use EASE for individual exposure characterizations. This study investigated whether EASE would accurately predict actual sampling results from a chemical manufacturing process. Personal breathing zone time-weighted average (TWA) monitoring data for two volatile organic chemicals--a common solvent (toluene) and a specialty monomer (chloroprene)--present in this manufacturing process were compared to EASE-generated estimates. EASE-estimated concentrations for specific tasks were weighted by task durations reported in the monitoring record to yield TWA estimates from EASE that could be directly compared to the measured TWA data. Two hundred and six chloroprene and toluene full-shift personal samples were selected from eight areas of this manufacturing process. The Spearman correlation between EASE TWA estimates and measured TWA values was 0.55 for chloroprene and 0.44 for toluene, indicating moderate predictive values for both compounds. For toluene, the interquartile range of EASE estimates at least partially overlapped the interquartile range of the measured data distributions in all process areas. The interquartile range of EASE estimates for chloroprene fell above the interquartile range of the measured data distributions in one process area, partially overlapped the third quartile of the measured data in five process areas and fell within the interquartile range in two process areas. EASE is not a substitute for actual exposure monitoring. However, EASE can be used in conditions that cannot otherwise be sampled and in preliminary exposure assessment if it is recognized that the actual interquartile range could be much wider and/or offset by a factor of 10 or more.  (+info)

Poly(chloroprene) is a synthetic crystallizable polymer used in several applications, including rubber gloves. The film formation of poly(chloroprene) latex offers opportunities to define structures at length scales between the molecular and macroscopic, thereby adjusting the elastomers mechanical properties. However, the connections between processing and the resultant film properties are not fully understood. Here, we investigate the competition between the coalescence of latex particles to build cohesive strength and their crystallization to raise the elastic modulus. We demonstrate that when coalescence precedes crystallization, the elastomer has greater extensibility and a higher tensile strength compared to when crystallization occurs during coalescence. The mechanical properties of poly(chloroprene) were tuned by blending two colloids with differing gel contents and crystallizabilities. Heating above poly(chloroprene)s melting temperature allows increased particle interdiffusion and ...

Residents of St. John the Baptist Parish could have an increased risk of cancer, as the EPA finds the Denka Performance Elastomer plant in LaPlace is releasing carcinogens into the air. Wilma Subra with the Louisiana Environmental Action Network says the facility is releasing huge quantities of chloroprene into the air, which can pose a serious health risk to the community.. It causes liver cancer, lung cancer, kidney cancer, colon cancer, and leukemia, as well as a lot of acute impacts like burning of the eyes, burning of the skin, respiratory problems, Subra said.. Air testing found residents had been subjected to 88 times the concentration of chloroprene the EPA allows. EPA inspectors found 31 valve leaks in the plant, which did not have the proper tools to measure the chemical emissions.

1,3-Butadiene is used as an intermediate in the production of elastomers, polymers, and other chemicals. Of the 1,3-butadiene used in 1978, 44% was used to manufacture styrene-butadiene rubber (a substitute for natural rubber, produced by copolymerization of 1,3-butadiene with styrene), and 19% was used to produce polybutane elastomer (a substance that increases resistance of tire products to wear, heat degradation, and blowouts). Chloroprene monomer, derived from 1,3-butadiene, is used exclusively to manufacture neoprene elastomers for non-tire and latex applications. Commercial nitrile rubber, used largely in rubber hoses, seals, and gaskets for automobiles, is a copolymer of 1,3-butadiene and acrylonitrile. Acrylonitrile- butadiene- styrene resins, usually containing 20%-30% 1,3-butadiene by weight, are used to make parts for automobiles and appliances. Other polymer uses include specialty polybutadiene polymers, thermoplastic elastomers, nitrile barrier resins, and K resins®. 1,3-Butadiene ...

Now that annual disclosure of the intelligence budget total has become routine, some legislators are seeking more transparency on intelligence spending.. As anticipated, the requested U.S. intelligence budget for Fiscal Year 2015 that was submitted to Congress this week fell below the current years level and continued a decline from the post-9/11 high that it reached in FY 2010.. The base funding request for the National Intelligence Program (NIP) for FY 2015 was $45.6 billion, while the base funding request for the Military Intelligence Program (MIP) was $13.3 billion. (Base funding does not include funding for overseas contingency operations, which is to be requested later in the year.). By comparison, the base funding request for the NIP in FY 2014 was $48.2 billion, and the base funding request for the MIP was $14.6 billion. Additional data on intelligence budget appropriations can be found here.. An unclassified summary of the FY 2015 National Intelligence Program budget request ...

The second largest economy on the planet - and arguably the most powerful - China, has launched a venomous attack on the United States, labelling it an espionage villain after former US spy Edward Snowden raised new allegations on the far-reaching US cyber-surveillance program, PRISM.. Snowdens latest allegations have the US spy-program directed squarely at Chinese targets.. The US is seeking to extradite the 30-year-old technician from Hong Kong, where he is holed up after leaking details of secret US intelligence programs to international media outlets.. Snowdens leaks revealed that the National Security Agency - NSA - has access to vast amounts of internet data such as emails, chat rooms and video under a government program known as PRISM. The South China Morning Post says documents and statements by Snowden show PRISM also hacked major Chinese telecom companies to access text messages and targeted Chinas top Tsinghua University.. US privacy proponentss have blasted Prism as ...

Nor do I. Its not like the Intelligence Committee is tasked to oversee the intelligence and intelligence-related activities of 17 elements of the US Government, and the Military Intelligence Program.

Its not like the letter to Inspector General Charles McCullough contains material lifted from the splash page of this website or anything. Its not as if the letter to Acting Inspector General Lynne Halbrooks demonstrates a serious concern about how the government labels things. Except the Halbrooks letter demands an investigation into ...
There has been muted and meek response coming from Europe in response to the uprisings for an end to dictatorial rule and for economic and social justice in Tunisia, Egypt and across the middle east. This weak response can be credited to a tsunami of Islamophobia that has swept through the western world since the Bush administrations propaganda campaign to win support for the perpetual war on terror. In Europe Muslim extremists are the boogeymen in the collective closet. The citizenry of Fortress Europe and the United States shudders in alarmist fear over often fabricated threats from intelligence programs geared toward ingraining the myth about the arab terrorist lurking around every corner. Irrational fears of the immigrants coming from North Africa and the Middle East to rape and destroy the traditions of Western European culture permeate European society as the NATO allies in Europe have continued to successfully perpetuate these misconceptions about Muslims and arabs even after Bushs ...
Attackers are using a sophisticated and stealthy piece of malware to infect Apache Web servers.. The backdoor, dubbed Linux/Cdorked.A, is one of the most sophisticated Apache backdoors we have seen so far, according to Pierre-Marc Bureau, security intelligence program manager at ESET.. The backdoor leaves no traces of compromised hosts on the hard drive other than its modified httpd binary, thereby complicating forensics analysis, he blogged. All of the information related to the backdoor is stored in shared memory. The configuration is pushed by the attacker through obfuscated HTTP requests that arent logged in normal Apache logs. This means that no command and control information is stored anywhere on the system, Bureau wrote.. Cdorked is designed to send users visiting a compromised site to servers hosting the notorious Blackhole exploit kit. According to ESET, the malware has already claimed hundreds of Web servers.. Just how the servers are initially being attacked is not clear, but ...
