... Home. Cancer. July 26, 2012 DNA damage in roofers due to PAH exposure -- possible cancer link July 26, 2012 Roofers and road construction workers who use hot asphalt are exposed to high levels of polycyclic aromatic hydrocarbons PAHs. A University of Colorado Cancer Center study published this week in the British Medical Journal Open shows that roofers have higher PAH blood-levels after a shift than before and that these high levels of PAHs are linked with increased rates of DNA damage, and potentially with higher cancer risk. "We've known for some time that roofers and road workers have higher cancer rates than the general population, but we also know roofers have a higher rates of smoking, alcohol use and higher UV exposure than the general population, and so it's been difficult to pinpoint the cause of higher cancer rates is it due to higher PAHs or is it due to lifestyle and other risk factors?" says Berrin Serdar, MD, PhD, investigator at the CU Cancer Center and assistant professor in the Departmen...

Air Levels of Carcinogenic Polycyclic Aromatic Hydrocarbons Following the World Trade Center Disaster. Abstract: The catastrophic collapse of the World Trade Center WTC on September 11, 2001, created an immense dust cloud followed by fires that emitted soot into the air of New York City NYC well into December. The particulate air pollutants contained mutagenic and carcinogenic polycyclic aromatic hydrocarbons PAHs. Based on temporal trends of individual PAH levels, we differentiated between fire and diesel sources and predicted PAH levels between 3 and 200 d after the disaster. Predicted PAH air concentrations on September 14, 2001, ranged from 1.3 to 15 ng/m3; these values are among the highest reported from outdoor sources. However, the high initial levels of PAHs may be associated with reproductive effects observed in the offspring of women who were or...

Polycyclic aromatic hydrocarbons are carcinogenic and mutagenic pollutants that settle in sediments, and disrupt the biology of sealife. This study took sediment samples from Glacier Bay, and measured the amount of PAHs present. Comparison samples from Puget Sound were also analyzed. No PAHs were found in Glacier Bay, while one site in Puget Sound, Pier 61, was heavily contaminated. A follow-up study would analyze Glacier Bay sediments after the cruise ship season had been underway for some months. Show ...

Sampling of NAWC wells in 1979 detected PCE 36 part per billion and TCE 293 ppb in three of the ten water supply wells. Evaluation of estimated exposure doses found that use of the NAWC drinking water supply is not expected to result in noncancer or cancer health effects. Noncancer MRLs for PCE and TCE are only available for acute 14 days or less exposures and were used to evaluate potential noncancer effects associated with drinking water exposures.

Ah-receptor-independent stimulation of hepatoma 27 culture cell proliferation by polycyclic aromatic hydrocarbons. MedLine Citation:. Abstract/OtherAbstract:. The proliferative effect of some compounds that are aryl hydrocarbon Ah receptor ligands was studied on hepatoma 27 cells with absent expression of Ah receptor. Compounds of the polycyclic aromatic hydrocarbon PAH class benzo/a/pyrene, 3-methylcholanthrene, 7,12-dimethylbenz/a/anthracene, and benzo/e/pyrene as well as β-naphthoflavone β-NF and chlorinated hydrocarbon Aroclor 1254 were studied. It was found that carcinogenic PAH and β-NF stimulate cell proliferation both under conditions of standard serum content and in a medium with low serum content. More efficient stimulation of proliferation was observed in the case of low serum content. Aroclor 1254 and benzo/e/pyrene did not stimulate cell proliferation. Stimulation of proliferatio...

This year Carlos Manzano received his PhD from the Simonich lab Project 5, and moved on from the OSU Superfund Research Center SRC. His research with the SRC focused on the development of new analytical techniques for the analysis of PAHs in complex environmental samples. Simonich, he developed an analytical method using comprehensive two dimensional GC GCxGC/ToF-MS to analyze around 90 PAHs in one chromatographic run, using a highly orthogonal column combination. For his PhD thesis, they wanted to focus specifically on oxy-PAHs and alkyl-PAHs, which were part of other SRP projects at OSU. They got some standards from other groups, and regularly collaborated with other cores and projects. Manzano C, Hoh E, Simonich SM.

*  Biodilution
'Biodilution' is the decrease in concentration of an element or pollutant with an increase in trophic level. This effect is primarily caused by the observed trend that an increase in algal biomass will reduce the overall concentration of a pollutant per cell, which ultimately contributes to a lower dietary input to grazers and higher-level aquatic organisms. The primary elements and pollutants of concern are heavy metals such as mercury, cadmium, and lead. This is a major concern since methylmercury, the most toxic mercury species, can be found in high concentrations in human-consumed fish and other aquatic organisms. Persistent organic pollutants, such as carcinogenic polycyclic aromatic hydrocarbons and alkylphenols, have also shown to biodilute in the marine environment. Numerous studies have linked lower mercury concentrations in zooplankton found in eutrophic nutrient-rich and highly productive as compared to oligotrophic low nutrient aquatic environments. Nutrient enrichment mainly phosphorus and nitrog...

(1/632) HPLC/fluorescence determination of anti-BPDE-DNA adducts in mononuclear white blood cells from PAH-exposed humans.

The aim of this study was to compare (+/-)-r-7,t-8-dihydroxy-t-9,10-oxy-7,8,9,10-tetrahydrobenzo[a]pyrene (anti-BPDE)-DNA adduct levels in groups of humans subjected to various levels of polycyclic aromatic hydrocarbon (PAH) (benzo[a]pyrene) exposure. An HPLC/fluorescence method was applied to detect specifically anti-BPDE-DNA adducts in mononuclear white blood cells [lymphocyte plus monocyte fraction (LMF)] from humans exposed to PAHs. A total of 130 subjects comprised the sample population: 26 psoriatic patients (3 days after clinical coal tar treatment of the skin), 15 coke oven workers, 19 chimney sweeps, 36 aluminium anode plant workers and 34 non-occupationally PAH-exposed subjects (controls). PAH exposure was assessed in each group by means of the urinary excretion of 1-pyrenol (mean group levels: 1.2, 0.7, 0.3, 65.0 and 0.1 micromol/mol creatinine in coke oven workers, chimney sweeps, aluminium plant anode workers, psoriatic patients and non-occupationally PAH-exposed subjects, respectively). HPLC/fluorescence analysis of BPDE-DNA adducts showed that the percentage of subjects with adduct levels exceeding the 95 percentile control subject value (8.9 adducts/10(8) nucleotides) was significantly high in coke oven workers (46.7%) and chimney sweeps (21.0%) (chi2 test, P < 0.01 and P < 0.05, respectively) but not in aluminium plant workers (11.1%) and psoriatic patients (0%). The increase in BPDE-DNA adduct levels in LMF (Ln values) was significantly related to chronic inhalatory and high PAH exposure (linear multiple regression analysis, F = 6.37, P < 0.01; t = 4.2, P < 0.001). Skin acute (or short-term) and high PAH exposure, charcoal-grilled meat consumption and smoking habit did not seem to influence BPDE-DNA adduct formation in LMF.  (+info)

(2/632) Structure-activity relationship of schisandrins in enhancing liver mitochondrial glutathione status in CCl4-poisoned mice.

AIM: To explore whether the methylenedioxy group and cyclooctadiene ring of the dibenzocyclooctadiene skeleton of schisandrins (Sch) play a role in the liver mitochondrial glutathione status enhancing activity. METHOD: The effects of three dibenzocyclooctadiene derivatives, Sch A, Sch B, Sch C, and a synthetic intermediate of Sch C, (dimethyl biphenyl dicarboxylate, DBD) on carbon tetrachloride (CCl4)-hepatotoxicity and liver mitochondrial glutathione status were examined in mice. RESULTS: Pretreating mice with intragastric Sch B, Sch C, or DBD 1.mmol.kg-1.d-1 for 3 d protected against CCl4-hepatotoxicity. The hepatoprotection afforded by Sch B or Sch C pretreatment was associated with increases in liver mitochondrial reduced glutathione (mtGSH) level and glutathione reductase (mtGRD) activity, an indication of enhanced mitochondrial glutathione status. In contrast, the hepatoprotective action of DBD was not accompanied by any detectable changes in mtGSH level and mtGRD activity. CONCLUSION: Both the methylenedioxy group and the cyclooctadiene ring of the dibenzocyclooctadiene molecule are important structural determinants in the enhancement of liver mitochondrial glutathione status.  (+info)

(3/632) Dose-dependent preferential binding of polycyclic aromatic hydrocarbons to reiterated DNA of murine skin cells in culture.

The distribution of active metabolites of polycyclic aromatic hydrocarbons bound to reiterated or unique regions of murine DNA has been studied by a DNA-DNA renaturation technique. Murine skin cells were exposed to different doses of radioactive polycyclic aromatic hydrocarbons for 24 hr; then the hydrocarbon-labeled DNA was isolated, fragmented, and denatured. Renaturation kinetics and thermal stabilities of DNA-DNA duplexes were studied. At high carcinogen doses, polycyclic aromatic hydrocarbon adducts seem to be distributed equally among the DNA of all reiteration frequencies. At low carcinogen doses, however, a dose-dependent preferential binding to reiterated DNA sequences occurs. An inverse linear relationship appears to exist between the enrichment of hydrocarbon adducts in reiterated DNA sequences and the logarithm of the amount of total hydrocarbon bound to DNA.  (+info)

(4/632) Cancer initiation by polycyclic aromatic hydrocarbons results from formation of stable DNA adducts rather than apurinic sites.

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants with high carcinogenic potencies that have been linked to the etiology of human cancers through their presence in cigarette smoke and environmental mixtures. They are metabolically activated in cells by cytochrome P450 enzymes and/or peroxidases to reactive intermediates that damage DNA. One pathway of activation forms dihydrodiol epoxides that covalently bind to exocyclic amino groups of purines in DNA to form stable adducts. Another pathway involves formation of radical cations that bind to the N7 or C8 of purines to form unstable adducts that depurinate to leave apurinic (AP) sites in DNA. In the present study the proportions of stable DNA adducts and AP sites formed by the carcinogenic PAHs dibenzo[a,l]-pyrene (DB[a,l]P), 7,12-dimethylbenz[a]anthracene (DMBA), and benzo[a]pyrene (B[a]P) have been investigated in a target tissue for carcinogenesis, mouse epidermis. After topical application of the PAHs on the skin of female SENCAR mice epidermal DNA was isolated and the formation of stable DNA adducts was measured by (33)P-postlabeling and HPLC analysis. AP sites in DNA were measured with an aldehyde reactive probe in a slot-blot assay. At both 4 and 24 h after exposure, DB[a,l]P formed significantly higher amounts of stable DNA adducts than DMBA, and B[a]P exhibited the lowest level of binding. In contrast, the number of AP sites present in mice treated with these PAHs was in the order: DMBA > B[a]P >> DB[a,l]P. The level of AP sites was significantly lower than the level of stable adducts for each PAH. The most potent carcinogen, DB[a,l]P, induced the highest level of stable adducts and the lowest level of AP sites in epidermal DNA. These results indicate that stable DNA adducts rather than AP sites are responsible for tumor initiation by carcinogenic PAHs.  (+info)

(5/632) Environmental pollution and human exposure to polycyclic aromatic hydrocarbons in the east Baltic region.

Environmental contamination by polycyclic aromatic hydrocarbons (PAH) and human exposure were surveyed in the east Baltic region. Polluted and heavily industrialized areas are upper Silesia in Poland, northern Bohemia in the Czech Republic, and the northeast part of Estonia. In Estonia the pollution is in a defined geographic area, where lung cancer incidence is higher than elsewhere. In Silesia, exposure of some 5 million people appears to be elevated; DNA (deoxyribonucleic acid) adduct levels in white blood cells are increased in groups of residents with apparently only environmental exposure. By extrapolation, some 150 annual lung cancer cases could be predicted due to PAH in Silesia. Air levels of benzo[a]pyrene were increased in northern Bohemia, and domestic heating and power plants using brown coal appeared to be major contributors to particulate air pollution in winter. Further studies are needed to assess health risks of PAH exposure in central and eastern Europe.  (+info)

(6/632) Alternative pathways of polycyclic aromatic hydrocarbons activation: the formation of polar DNA adducts.

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants, and some are potent carcinogens in rodents. Carcinogenic PAHs are activated in the cells to metabolites that react with DNA to form covalent adducts. For most PAHs the reactive, electrophilic species which bind to DNA, are bay-region diol-epoxides. Application of 32P-postlabeling to PAH-DNA adducts analysis revealed that for some PAHs the adduct profiles generated in model systems are more complex and include adducts which are more polar than those formed by classic bay-region diol-epoxides. This minireview summaries the information gained on typical representatives of polar PAH-DNA adducts. Formation of triol-epoxide-DNA adducts was proposed for chrysene and a non-alterant PAH, benzo[b]fluoranthene (B[b]F). 5-OH-B[b]F, the precursor of B[b]F triol-epoxide, was found to be a potent tumor initiator in mouse skin. For planar PAHs such as dibenzanthracenes the possibility of bis-diol epoxide-DNA adducts formation was suggested. The most comprehensive data were obtained for dibenz[a,j]anthracene (DB[a,j]A). This hydrocarbon when applied to SENCAR mouse skin forms up to 23 species of adducts, most of which are polar. Among these polar adducts seven were identified as derived from DB[aj]A-3,4-10,11-bis-diol. Analysis of tumor-initiating activity showed, however, that this proximate metabolite was inactive in this respect. In contrast, an excellent correlation was observed between levels of less polar DNA adducts (i.e. those derived from bay-region diolepoxides) and skin tumor initiating activity of DB[a,j]A. Thus, while triol-epoxides seems to be involved in tumor initiating activity of the parent compound, non alterant B[b]F, the significance of bis-diol epoxide-DNA adducts, at least those derived from DB[aj]A, is minor.  (+info)

(7/632) Mutability of different genetic loci in mammalian cells by metabolically activated carcinogenic polycyclic hydrocarbons.

The relationship between carcinogenesis and mutagenesis in mammalian cells has been determined with 10 polycyclic hydrocarbons with different degrees of carcinogenicity. Mutagenesis was determined in Chinese hamster cells with genetic markers that affect the surface membrane, nucleic-acid synthesis, and protein synthesis. The mutations were characterized by resistance to ouabain, 8-azaguanine, and temperature. Mutagenesis by the carcinogens required metabolic activation and this was provided by the presence of lethally irradiated metabolizing cells. The degree of carcinogenicity was related to the degree of mutagenicity for all three genetic markers. The most potent carcinogen, 7,12-dimethylbenz[a]anthracene, gave the highest mutagenicity and mutagenicity was obtained with 0.01 mug/ml. Treatment of the cells with aminophylline, which increases polycyclic hydrocarbon metabolism, increased mutagenesis by the carcinogens. It is suggested that such an experimental system with these and other mammalian cells should be useful as a sensitive assay for hazardous environmental chemicals.  (+info)

(8/632) Effect of plant matrix and fluid ethanol concentration on supercritical fluid extraction efficiency of schisandrin derivatives.

An investigation of the effect of plant matrix on the supercritical fluid extraction efficiency of five schisandrin derivatives is reported, exhibiting a great difference with respect to extraction efficiency depending on the matrix. Pure supercritical CO2 at 60 degrees C and 34.0 MPa cannot fully recover schisandrin derivatives from the leaves as much as from the other matrices. Only 36.9% of these compounds are extracted from leaves of Schisandra chinensis by supercritical CO2 in comparison with organic solvent extraction. However, more than 80% of schisandrin derivatives are obtained from both stem and fruit parts. Ethanol addition also shows a different effect depending on plant matrix; that is, CO2 modified with 10% ethanol could enhance the yield of schisandrin derivatives from leaves by four times when compared with that of pure CO2, but it has little effect on both stems and fruits.  (+info)

if you isolate each muscle group and do more reps than compound lifting than they will grow faster.


What are some examples of compound exercises?


I heard compound exercises are the best for muscle growth. The only one i know of right now is pullups. What are some other ones?

Is a skillet a simple or compound machine?


I'm doing a physical science project and I am wondering if this is a simple or compound machine. If it is a compound machine, what type of simple machines are contained in it?
----------

Depending on what you are cooking it can be either simple or compound.
If you are using it to saute, which involves moving the pan in a fashion to make the food jump, then catching it in the pan. Then you are using the skillet handle as a lever and your wrist, is sort of acting as a fulcrum. 
Furthermore, if you are cooking something with liquid in it, you can tilt the pan toward you while it is on top of the heat source, and gravity will cause all the liquid will gather at the bottom of the pan close to the handle. The heat will cause the liquid to evaporate, and you will have a reduced liquid after a time without burning the food in the rest of the pan. Doing this with the skillet, makes it an inclined plane. So if you really want to be specific, it can be a compound machine or it can be a simple machine... Depending on what you are cooking.


How do you treat a compound fracture when you can't afford medical bills?


My boyfriend (Brad) was skiing and he got a compound fracture in his arm.  How can we care for it if we can't afford medical bills?  How do we take care of it at home?
----------

You cannot fix something like this at home.

You have no way of knowing if he has done damage within his arm that you cannot see.

Take him to the doctor.  Most physicians will go easy on you as far as billing goes if you explain that you don't have insurance (or have crappy insurance).  Their billing departments will set you up on a payment plan so that you can pay off the balance in installments.


How do I avoid this toxic compound in my food?


I am trying to avoid dihydrogen monoxide, it's a compound that's in everything at the store and everyone who has consumed it has died of illness or injuries from the illness.

I was wondering if anyone can give me stores that sell dihydrogen monoxide free food and dihydrogen monoxide free water. Or ways I can avoid this toxin.
----------

It's a joke.
Bake everything until it's crisp and you would die of dehydration.
