The direct spectrophotometric observation of benzo(a)pyrene phenol formation by liver microsomes. (1/4452)

Optical spectral repetitive scan analysis during the oxidative metabolism of benzo(a)pyrene by liver microsomal suspensions reveals the time-dependent formation of an intermediate(s) of which the visible spectra resemble those of several benzo(a)pyrene phenols. Liver microsomes from 3-methylcholanthrene-treated rats showed a greater rate of formation of the phenols than did microsomes from control animals; the rate of formation catalyzed by liver microsomes from phenobarbital-pretreated rats was intermediate. When 3-hydroxybenzo(a)pyrene was used as a standard for comparison of activity, the rates of formation of phenols were compared when measured by fluorometric, spectrophotometric, or high-pressure liquid chromatographic analytical techniques. An epoxide hydrase inhibitor, 1,1,1-trichloropropene-2,3-oxide, enhanced phenol formation regardless of the source of liver microsomes, and 7,8-benzoflavone inhibited control and 3-methylcholanthrene-induced microsomal metabolism of benzo(a)pyrene, 7,8-Benzoflavone did not effect benzo(a)pyrene metabolism by liver microsomes from phenobarbital-pretreated rats. The effect of inhibitors on the spectrophotometric assay correlates well with the results obtained from benzo(a)pyrene metabolite analysis using high-pressure liquid chromatography.  (+info)

Hierarchical cluster analysis applied to workers' exposures in fiberglass insulation manufacturing. (2/4452)

The objectives of this study were to explore the application of cluster analysis to the characterization of multiple exposures in industrial hygiene practice and to compare exposure groupings based on the result from cluster analysis with that based on non-measurement-based approaches commonly used in epidemiology. Cluster analysis was performed for 37 workers simultaneously exposed to three agents (endotoxin, phenolic compounds and formaldehyde) in fiberglass insulation manufacturing. Different clustering algorithms, including complete-linkage (or farthest-neighbor), single-linkage (or nearest-neighbor), group-average and model-based clustering approaches, were used to construct the tree structures from which clusters can be formed. Differences were observed between the exposure clusters constructed by these different clustering algorithms. When contrasting the exposure classification based on tree structures with that based on non-measurement-based information, the results indicate that the exposure clusters identified from the tree structures had little in common with the classification results from either the traditional exposure zone or the work group classification approach. In terms of the defining homogeneous exposure groups or from the standpoint of health risk, some toxicological normalization in the components of the exposure vector appears to be required in order to form meaningful exposure groupings from cluster analysis. Finally, it remains important to see if the lack of correspondence between exposure groups based on epidemiological classification and measurement data is a peculiarity of the data or a more general problem in multivariate exposure analysis.  (+info)

Complete sequence of a 184-kilobase catabolic plasmid from Sphingomonas aromaticivorans F199. (3/4452)

The complete 184,457-bp sequence of the aromatic catabolic plasmid, pNL1, from Sphingomonas aromaticivorans F199 has been determined. A total of 186 open reading frames (ORFs) are predicted to encode proteins, of which 79 are likely directly associated with catabolism or transport of aromatic compounds. Genes that encode enzymes associated with the degradation of biphenyl, naphthalene, m-xylene, and p-cresol are predicted to be distributed among 15 gene clusters. The unusual coclustering of genes associated with different pathways appears to have evolved in response to similarities in biochemical mechanisms required for the degradation of intermediates in different pathways. A putative efflux pump and several hypothetical membrane-associated proteins were identified and predicted to be involved in the transport of aromatic compounds and/or intermediates in catabolism across the cell wall. Several genes associated with integration and recombination, including two group II intron-associated maturases, were identified in the replication region, suggesting that pNL1 is able to undergo integration and excision events with the chromosome and/or other portions of the plasmid. Conjugative transfer of pNL1 to another Sphingomonas sp. was demonstrated, and genes associated with this function were found in two large clusters. Approximately one-third of the ORFs (59 of them) have no obvious homology to known genes.  (+info)

Isolation from estuarine sediments of a Desulfovibrio strain which can grow on lactate coupled to the reductive dehalogenation of 2,4, 6-tribromophenol. (4/4452)

Strain TBP-1, an anaerobic bacterium capable of reductively dehalogenating 2,4,6-tribromophenol to phenol, was isolated from estuarine sediments of the Arthur Kill in the New York/New Jersey harbor. It is a gram-negative, motile, vibrio-shaped, obligate anaerobe which grows on lactate, pyruvate, hydrogen, and fumarate when provided sulfate as an electron acceptor. The organism accumulates acetate when grown on lactate and sulfate, contains desulfoviridin, and will not grow in the absence of NaCl. It will not utilize acetate, succinate, propionate, or butyrate for growth via sulfate reduction. When supplied with lactate as an electron donor, strain TBP-1 will utilize sulfate, sulfite, sulfur, and thiosulfate for growth but not nitrate, fumarate, or acrylate. This organism debrominates 2-, 4-, 2,4-, 2,6-, and 2,4,6-bromophenol but not 3- or 2,3-bromophenol or monobrominated benzoates. It will not dehalogenate monochlorinated, fluorinated, or iodinated phenols or chlorinated benzoates. Together with its physiological characteristics, its 16S rRNA gene sequence places it in the genus Desulfovibrio. The average growth yield of strain TBP-1 grown on a defined medium supplemented with lactate and 2,4,6-bromophenol is 3.71 mg of protein/mmol of phenol produced, and the yield was 1.42 mg of protein/mmol of phenol produced when 4-bromophenol was the electron acceptor. Average growth yields (milligrams of protein per millimole of electrons utilized) for Desulfovibrio sp. strain TBP-1 grown with 2,4,6-bromophenol, 4-bromophenol, or sulfate are 0.62, 0.71, and 1.07, respectively. Growth did not occur when either lactate or 2,4,6-bromophenol was omitted from the growth medium. These results indicate that Desulfovibrio sp. strain TBP-1 is capable of growth via halorespiration.  (+info)

In vivo demonstration of H3-histaminergic inhibition of cardiac sympathetic stimulation by R-alpha-methyl-histamine and its prodrug BP 2.94 in the dog. (5/4452)

1. The aim of this study was to investigate whether histamine H3-receptor agonists could inhibit the effects of cardiac sympathetic nerve stimulation in the dog. 2. Catecholamine release by the heart and the associated variation of haemodynamic parameters were measured after electrical stimulation of the right cardiac sympathetic nerves (1-4 Hz, 10 V, 10 ms) in the anaesthetized dog treated with R-alpha-methyl-histamine (R-HA) and its prodrug BP 2.94 (BP). 3. Cardiac sympathetic stimulation induced a noradrenaline release into the coronary sinus along with a tachycardia and an increase in left ventricular pressure and contractility without changes in mean arterial pressure. Intravenous administration of H3-receptor agonists significantly decreased noradrenaline release by the heart (R-HA at 2 micromol kg(-1) h(-1): +77 +/- 25 vs +405 +/- 82; BP 2.94 at 1 mg kg(-1): +12 +/- 11 vs +330 +/- 100 pg ml(-1) in control conditions, P < or = 0.05), and increases in heart rate (R-HA at 2 micromol kg(-1) h(-1): +26 +/- 8 vs +65 +/- 10 and BP 2.94 at 1 mg kg(-1): +30 +/- 8 vs 75 +/- 6 beats min(-1), in control conditions P < or = 0.05), left ventricular pressure, and contractility. Treatment with SC 359 (1 mg kg(-1)) a selective H3-antagonist, reversed the effects of H3-receptor agonists. Treatment with R-HA at 2 micromol kg(-1) h(-1) and BP 2.94 at 1 mg kg(-1) tended to decrease, while that with SC 359 significantly increased basal heart rate (from 111 +/- 3 to 130 +/- 5 beats min(-1), P < or = 0.001). 4. Functional H3-receptors are present on sympathetic nerve endings in the dog heart. Their stimulation by R-alpha-methyl-histamine or BP 2.94 can inhibit noradrenaline release by the heart and its associated haemodynamic effects.  (+info)

Antioxidative and chelating activities of phenylpropanoid glycosides from Pedicularis striata. (6/4452)

AIM: To study the antioxidative and iron chelating activities of phenylpropanoid glycosides (PPG) isolated from a Chinese herb Pedicularis striata. METHODS: Antioxidative effects of PPG on lipid peroxidation induced by FeSO4-edetic acid in linoleic acid were measured by thiobarbituric acid method. Chelating activities of PPG for Fe2+ were tested by differential spectrum method. RESULTS: The reaction rates (A532.min-1) of lipid peroxidation were 0.0046 in the control, 0.0021 in verbascoside group, and 0.0008 in isoverbascoside group. The chelating activity of isoverbascoside was 2-fold stronger than that of verbascoside. Permethyl verbascoside showed neither antioxidative nor chelating activities. CONCLUSION: The inhibitory effects of PPG with phenolic hydroxy groups on lipid peroxidation are owing to their chelating properties. Under physiological condition PPG-Fe2+ chelates are sufficiently stable. Thus PPG are able to inhibit the Fe(2+)-dependent lipid peroxidation in vivo through chelating Fe2+ and exhibit their therapeutic potential by the same mechanism in vitro.  (+info)

Developing hypothalamic dopaminergic neurones as potential targets for environmental estrogens. (7/4452)

Environmental chemicals which mimic the actions of estrogen have the potential to affect any estrogen responsive tissue. The aim of the present study was to investigate their potential to mimic the effects of 17beta-estradiol (E2) on developing primary rat hypothalamic dopaminergic (DA) neurones maintained in a chemically defined medium. We now show that both E2 and octylphenol (OP), but not the non-aromatizable androgen, dihydrotestosterone, enhanced the uptake of [3H]DA by the cultured cells, whereas they had no effect on the uptake of [14C]GABA. Although the sensitivity of responses may change with the age of the developing cultures, the dose response curves for E2 and OP were typically 'bell-shaped', with a rise in response followed by a decline to control levels with increasing concentrations. Effects were seen as low as 10(-14) M for E2 and 10(-11) M for OP. Responses to E2 (10(-12) M) and OP (10(-9) M) were reversed in the presence of the antiestrogen, ZM 182780 (10(-5) M). This study thus provides direct evidence, using a mechanistic rather than toxicological end-point, in support of the hypothesis that inappropriate exposure to environmental estrogens at critically sensitive stages of development, could potentially perturb the organisational activities of estrogen on selected neuronal populations in the CNS.  (+info)

Characterization of the pyoluteorin biosynthetic gene cluster of Pseudomonas fluorescens Pf-5. (8/4452)

Ten genes (plt) required for the biosynthesis of pyoluteorin, an antifungal compound composed of a bichlorinated pyrrole linked to a resorcinol moiety, were identified within a 24-kb genomic region of Pseudomonas fluorescens Pf-5. The deduced amino acid sequences of eight plt genes were similar to the amino acid sequences of genes with known biosynthetic functions, including type I polyketide synthases (pltB, pltC), an acyl coenzyme A (acyl-CoA) dehydrogenase (pltE), an acyl-CoA synthetase (pltF), a thioesterase (pltG), and three halogenases (pltA, pltD, and pltM). Insertions of the transposon Tn5 or Tn3-nice or a kanamycin resistance gene in each of these genes abolished pyoluteorin production by Pf-5. The presumed functions of the eight plt products are consistent with biochemical transformations involved in pyoluteorin biosynthesis from proline and acetate precursors. Isotope labeling studies demonstrated that proline is the primary precursor to the dichloropyrrole moiety of pyoluteorin. The deduced amino acid sequence of the product of another plt gene, pltR, is similar to those of members of the LysR family of transcriptional activators. pltR and pltM are transcribed divergently from the pltLABCDEFG gene cluster, and a sequence with the characteristics of a LysR binding site was identified within the 486-bp intergenic region separating pltRM from pltLABCDEFG. Transcription of the pyoluteorin biosynthesis genes pltB, pltE, and pltF, assessed with transcriptional fusions to an ice nucleation reporter gene, was significantly greater in Pf-5 than in a pltR mutant of Pf-5. Therefore, PltR is proposed to be a transcriptional activator of linked pyoluteorin biosynthesis genes.  (+info)

Levels of inflammatory cytokines are raised in chronic obstructive pulmonary disease ( COPD). A diet rich in antioxidant vitamins may protect against the development of COPD. This study examined the effects of phenolic compounds and food sources on cytokine and antioxidant production by A549 cells. The effects of the following phenolic compounds on basal and interleukin ( IL)-1- stimulated release of IL-8, IL-6, and reduced glutathione (GSH) were examined: resveratrol; Bouvrage, a commercially available raspberry juice ( Ella Drinks Ltd., Alloa, Clacksmannanshire, UK); and quercetin 3 - sulfate. Purification of the raspberry juice by high- performance liquid chromatography gave three fractions: Fraction 1 contained phenolic acid and vitamin C, Fraction 2 contained flavonoids and ellagic acid, and Fraction 3 contained anthocyanins and ellagitannins. IL-8 production was increased in the presence of IL-1 ( 165 vs. 6,011 pg/mL, P ,.0001). None of the compounds tested had any significant effect on ...

abstractNote = {One of the main problems in Mexico and in the World is the waste water pollution of a great variety of industrial processes by organic compounds. Among those ones the phenol compounds which are highly toxic, refractories (to the chemical degradation) and poorly biodegradable. This is due in a large extent to the problem created by the accelerated increase in the environmental pollution in the cities and industrial centers. The phenol compounds are used in a great variety of industries such as the production of resins, plasticizers, antioxidants, pesticides, colourings, disinfectants, etc. These phenol compounds are specially harmful, since they have repercussions on the flora of plants of biological treatment of water affecting its operation. The main objective of this work is to evaluate the capacities of phenol detention and its derivatives in an hydrotalcite type compound and diminishing with it the presence in water, in this case, of solutions prepared in the laboratory.

Effects of octylphenol and bisphenol A on the expressions of calcium transport genes during pregnancy in miceEffects of octylphenol and bisphenol A on the expressions of calcium transport genes during pregnancy in mice
Introduction: Octylphenol (OP) is a degradation product of alkylphenol ethoxylates that are widely used to in rubber, pesticides and paints. Bisphenol A (BPA) is an organic compound with two functional phenol groups and used to make polycarbonate plastic and epoxy resins, along with other applications. OP and BPA are known as endocrine disruptors that can induce inappropriate estrogenic action, and may disturb natural calcium metabolism. In the present study, the effects of OP and BPA on the calcium levels of serum and urine, and calcium transport genes were investigated in the duodenum, kidney and placenta of the pregnant mice.. Methods: From 6.5 to 16.5 days after post coitus (dpc), pregnant mice were orally given with ethylestradiol (EE, 0.2 mg/kg/day), OP (15, 45, or 135 mg/kg/day) or BPA (5 or 50 mg/kg/day) dissolved in corn oil. The duodenum, kidney, placenta, blood and urine were obtained from mice at day 18.5 of pregnancy.. Results: As a result, serum and urinary calcium levels were ...

Xenoestrogens such as alkylphenols and the structurally related plastic byproduct bisphenol A have recently been shown to act potently via nongenomic signaling pathways and the membrane version of estrogen receptor-α. Though the responses to these compounds are typically measured individually, they usually contaminate organisms that already have endogenous estrogens present. Therefore, we used quantitative medium-throughput screening assays to measure the effects of physiologic estrogens in combination with these xenoestrogens. We studied the effects of low concentrations of endogenous estrogens (estradiol, estriol, and estrone) at 10 pM (representing pre-development levels), and 1 nM (representing higher cycle-dependent and pregnancy levels) in combinations with the same levels of xenoestrogens in GH3/B6/F10 pituitary cells. These levels of xenoestrogens represent extremely low contamination levels. We monitored calcium entry into cells using Fura-2 fluorescence imaging of single cells. Prolactin

Exposure to toxic industrial chemicals that have capacity to disrupt the endocrine system, also known as endocrine disrupting chemicals (EDCs), has been increasingly associated with reproductive problems in human population. Bisphenol A (BPA; 4,4-(propane-2,2-diyl)diphenol) and 4-tert-octylphenol (OP; 4-(1,1,3,3-tetramethylbutyl)phenol) are among the most common environmental contaminants possessing endocrine disruption properties and are present in plastics, epoxy resins, detergents and other commercial products of common personal and industrial use. A metabolite of BPA, 4-Methyl-2,4-bis(4-hydroxyphenyl)pent-1-ene (MBP) is about 1000 times more biologically active compared to BPA. Epidemiological, clinical, and experimental studies have shown association of BPA and OP with adverse effects on male and female reproductive system in human and animals. The endocrine disruption activity can occur through multiple pathways including binding to steroid receptors. Androgen receptor (AR) and progesterone

Stagnant water bodies have generally received little attention regarding the presence of endocrine disruptive compounds, although they can integrate diverse pollutants from multiple different sources. Many compounds of anthropogenic as well as natural origin can contribute to the overall estrogenicity of surface waters and some of them can exhibit adverse effects on aquatic biota even in very low concentrations. This study focused on freshwater ponds and reservoirs affected by water blooms and determined the estrogenic activity of water by in vitro bioassay as well as concentrations of several important groups of estrogenic compounds (estrogenic hormones, alkylphenols, and phytoestrogens) by LC-MS/MS analyses. Estrogenic hormones were found at concentrations up to 7.1 ng.L-1, similarly to flavonoids, whose concentrations did not exceed 12.5 ng.L-1. Among alkylphenols, only bisphenol A and 4-tert-octylphenol were detected in levels reaching 100 ng.L-1 at maximum. Estrogenic activity of water ...

Alkylphenols are widely used industrial chemicals that act as detergents or surfactants. They are added to cosmetics, paints, pesticides, detergents and cleaning products. As a group they are highly toxic to aquatic organisms. Dozens of recent studies have documented the in-vitro and in-vivo estrogenic activity of alkylphenols in human cell lines and animals (Bechi 2006). Alkylphenols have been detected recently in surface waters contaminated with urban runoff and in wastewater effluent (Espejo 2002; Oros 2003).. Alkylphenols have been measured in air samples. One study found that newer homes, especially those with PVC materials, have more alkylphenol residues than older houses or outdoor air (Saito 2004).. ...

A HPLC method for simultaneous determination of 25 phenolic compounds in grape juice was optimized, validated and applied in the characterization of juices produced in São Francisco Valley (SFV), Brazil. The performance char- acteristics of the method were established by assays with standard solutions of phenolic compounds, spiked and unspiked samples. Linearity, matrix effects, trueness, precision, detection and quantification limits were evaluated. Linearity was demonstrated in the concentration ranges tested for all phenolic compounds. Significant matrix ef- fects were not identified for the studied compounds. Mean recoveries ranged from 86.18 to 106.50%, demonstrat- ing no lack of trueness. Precision of the method was confirmed for the 25 phenolic compounds, with acceptable repeatability relative standard deviations (from 0.71 to 9.24%) and within-reproducibility relative standard devia- tions (from 1.34 to 9.26%) for unspiked and spiked samples. The theoretical limits of detection and ...

Potential Sources of Bisphenol A in the Neonatal Intensive Care Unit | Articles | PediatricsPotential Sources of Bisphenol A in the Neonatal Intensive Care Unit | Articles | Pediatrics
In the current study, all infants had detectable urinary concentrations of total BPA, ranging from 2.0 to 196 µg/L. The median urinary BPA concentration in this group of premature infants was considerably higher (17.2 μg/L) than in healthy term infants aged 1 to 5 months (,0.45 μg/L) without known BPA exposure.21 Although immaturity of phase II metabolism may account for some of the association of urinary BPA concentrations with prematurity, premature infants have the ability to conjugate BPA.16 Interestingly, medical devices, but not nutritional intake, were positively associated with urinary BPA concentrations. On average, premature infants requiring ≥4 medical devices had urinary total BPA concentrations 1.6 times higher than those requiring fewer devices independent of their gestational age, gender, or nutritional intake. Respiratory devices were associated with higher urinary BPA concentrations than other devices. These findings suggest that medical devices were an important source of ...

Gestational urinary BPA concentrations were associated with some neurobehavioral measures at 3 years of age in this cohort. In particular, gestational BPA exposure was associated with higher scores for measures of anxiety, hyperactivity, emotional control, and behavioral inhibition. Similar to our previous findings, the effects of gestational BPA exposure on these behavioral domains were larger among girls than boys.2 The different responses to gestational BPA exposure were especially pronounced for hyperactivity; girls exhibited increases in hyperactivity, and boys exhibited decreases in hyperactivity. In contrast, childhood urinary BPA concentrations were less important predictors of behavior or executive functions in this study.. The findings presented are consistent with numerous studies demonstrating altered neurobehavior among BPA-exposed animals.14,38 Gestational BPA exposures might affect endocrine or other neurotransmitter pathways and disrupt sexual differentiation of the brain, to ...
BPA Exposure in the NICUBPA Exposure in the NICU
NIEHS Grant P30ES000002. A study, supported in part by the NIEHS, identified medical devices as a potential source of exposure to bisphenol A (BPA) among premature infants in neonatal intensive care units. BPA is used to manufacture polycarbonate plastics, which are used in medical devices such as intravenous administration sets, syringes, and catheters. The researchers looked at the urinary BPA concentration for 55 infants and categorized each infants medical device use as low or high based on the number and invasiveness of devices. They found that the median urinary total BPA concentration of infants who had required four or more medical devices for three previous days was significantly higher, 36.6 micrograms per liter (µg/l), than for the infants requiring three or less devices, who had a BPA concentration of 13.9 µg/l. The researchers also collected and analyzed breast milk or formula samples, and found that the increased BPA concentration was not associated with the infants nutritional ...

ALBERTO, María R.; MANCA DE NADRA, María C. and ARENA, Mario E.. Influence of phenolic compounds on the growth and arginine deiminase system in a wine lactic acid bacterium. Braz. J. Microbiol. [online]. 2012, vol.43, n.1, pp.167-176. ISSN 1517-8382. http://dx.doi.org/10.1590/S1517-83822012000100018.. The influence of seven phenolic compounds, normally present in wine, on the growth and arginine deiminase system (ADI) of Lactobacillus hilgardii X1B, a wine lactic acid bacterium, was established. This system provides energy for bacterial growth and produces citrulline that reacts with ethanol forming the carcinogen ethyl carbamate (EC), found in some wines. The influence of phenolic compounds on bacterial growth was compound dependent. Growth and final pH values increased in presence of arginine. Arginine consumption decreased in presence of protocatechuic and gallic acids (31 and 17%, respectively) and increased in presence of quercetin, rutin, catechin and the caffeic and vanillic phenolic ...

It is in your food containers, water bottles, and 90 percent of us have it in our bloodstream. It may also be a prime candidate for causing wheezing in children if pregnant mothers come into contact with it. Experimental research in bisphenol A, (BPA) suggests that prenatal BPA exposure causes asthma in mice. No firm data yet exists for humans but results are not looking good.. Adam Spanier, M.D., Ph.D., assistant professor of pediatrics at Penn State College of Medicine, studied 367 children, 99 percent of whom were born to mothers who had detectable BPA levels during pregnancy. Twice a year for three years, the parents reported back with any signs of wheezing in the children. At six months of age, twice as many children were reported with wheezing from mothers who had higher BPA than those who had mothers with lower BPA levels. These effects may have diminished as the children aged however.. Researchers then looked at the levels of BPA in the women during certain times of their pregnancies and ...

In this study, the concentration of alkylphenol ethoxylates (APEs) and brominated flame retardants (BFRs) were determined in fish samples, Labeo umbratus and Carp, collected from the Vaal River in South Africa. Ultrasonic-assisted extraction technique was used to extract the organic contaminants from fish samples, and the resulting extract was purified by sulphuric acid lipid removal followed by Strata X-cartridge SPE clean-up. The APEs and BFRs were derivatized using heptafluorobutyric anhydride before analysis with GC-MS. In both types of fish samples, lower oligomers of APEs were more abundant than the higher oligomers, while HBCD, BDE99 and PBB101 were the dominant BFRs. The concentrations of these pollutants ranged from 1.061 ng/g lipids (t-BP) in Labeo umbratus to 11.860 ng/g lipids (HBCD) in Carp.

First peer-reviewed study finds BPA levels in US foods 1,000 times less than limitsFirst peer-reviewed study finds BPA levels in US foods 1,000 times less than limits
Arnold J. Schecter and colleagues note that BPA is used in lining metal cans and in polycarbonate plastics such as baby bottles, although some manufacturers are switching to BPA-free products. "In humans, BPA is associated with cardiovascular disease, diabetes, and male sexual dysfunction in exposed workers," they state. "Food is a major exposure source. We know of no studies reporting BPA in U.S. fresh food, canned food, and food in plastic packaging in peer reviewed journals." To fill that gap in scientific knowledge, the scientists measured BPA levels in 105 human, cat, and dog foods. They detected BPA in 63 of 105 human food samples from grocery stores in Dallas, and present a detailed list of foods, brands, and BPA levels in the text of the study. The levels were lower than the 50 micrograms per kilogram of body weight standard used by EPA and EFSA and comparable to levels detected in the past. Schecter noted that some studies have shown adverse effects associated with exposure to BPA at ...

The amounts of total polyphenol and flavonoids in the Korean EEP samples ranged from 49 to 239 mg gallic acid equivalent (GAE)/g EEP (Brazilian, Chinese, and Australian samples, 127-142 mg GAE/g EEP) and from 21 to 50 mg quercetin equivalent (QE)/g EEP (Brazilian, Chinese, and Australian samples, 33-53 mg QE/g EEP), respectively. Correlation coefficient analysis showed that total polyphenol contents may be negatively correlated with 2,2-diphenyl-1-picrylhydrazyl free radical scavenging activity (r = -0.872) and total flavonoid content has no correlation with the activity (r = 0.071). No direct correlation between BACE-1 inhibition, AChE inhibition, or antiproliferative activity and total polyphenol or total flavonoid content in Korean EEP samples was found. Gram-positive and Gram-negative bacteria were observed to have different degrees of antimicrobial susceptibility to the EEP samples examined, although ciprofloxacin susceptibility among the bacterial groups did not differ greatly ...
BPA Levels Soar After Eating Canned Soup | Food CourtBPA Levels Soar After Eating Canned Soup | Food Court
MSNBC is reporting on a new study that found eating canned food every day may raise the levels of the compound bisphenol A (BPA) in a persons urine more than previously suspected, a new study suggests.. The study found people who ate a serving of canned soup every day for five days showed higher levels of BPA in their systems than those who ate no soup. The participants who ate soup during the five day test had BPA levels of 20.8 micrograms per liter of urine, whereas people who instead ate fresh soup had levels of 1.1 micrograms per liter, according to the study.. Food Court previously reported on BPA findings in popular childrens soups. In that case, and here, BPA is found in many canned foods - it is a byproduct of the chemicals used to prevent corrosion.. When the researchers looked at the rise in BPA levels seen in the average participant who ate canned soup compared with those who ate fresh soup, they found a 1,221 percent jump.. The FDA does not currently regulate BPA levels and is ...
The Neighborhood Toxicologist: Polycarbonate plastics: if only toxicology could be that clearThe Neighborhood Toxicologist: Polycarbonate plastics: if only toxicology could be that clear
An ongoing debate about the health impacts of bisphenol A (BPA), the ubiquitous chemical used in production of polycarbonate - that hard clear plastic we use for eating, drinking, and storing food - continues, according to a recent article by Janet Raloff published in the September 29 issue of Science News. Her analysis provides good insight into why we often hear conflicting reports when it comes to environmental and health impacts of chemicals.. Raloff reports on the conflicting results of two different panels recruited by the National Toxicology Program (NTP) and charged with reviewing and evaluating the potential developmental and reproductive impacts of BPA. While one panel "labeled as confident its assessment that BPA at low doses has had negative effects on experimental animals," and that such findings were suggestive of impacts in humans, the other panel "concluded that current BPA exposures appear to pose little risk to humans.". According to Raloff, one of the differences cited in ...
Computational study of the adsorption and dissociation of phenol on Pt and Rh surfacesComputational study of the adsorption and dissociation of phenol on Pt and Rh surfaces
The adsorption of phenol on flat and stepped Pt and Rh surfaces and the dissociation of hydrogen from the hydroxyl group of phenol on Pt(111) and Rh(111) were studied by density functional calculations. On both Pt(111) and Rh(111), phenol adsorbs with the aromatic ring parallel to the surface and the hydroxyl group tilted away from the surface. Furthermore, adsorption on stepped surfaces was concluded to be unfavourable compared to the (111) surfaces due to the repulsion of the hydroxyl group from the step edges. Transition state calculations revealed that the reaction barriers, associated with the dissociation of phenol into phenoxy, are almost identical on Pt and Rh. Furthermore, the oxygen in the dissociated phenol is strongly attracted by Rh(111), while it is repelled by Pt(111).
Activated carbons as green and effective catalysts for generation of reactive radicals in degradation of aqueous phenolActivated carbons as green and effective catalysts for generation of reactive radicals in degradation of aqueous phenol
Several activated carbons (ACs) were used as metal-free catalysts for degradation of a toxic organiccompound, phenol, in the presence of different oxidants, H2O2, peroxydisulfate (PS) and peroxymonosulfate (PMS). It was found that ACs were effective in heterogeneous activation of PMS toproduce sulfate radicals for degradation of phenol, much better than H2O2 and PS. Particle size of AC significantly influenced AC activity, and powder AC was much more effective than granular AC. The complete phenol removal could be achieved in 15 min on powder activated carbon (PAC) under the conditions of [phenol] = 25 mg L-1, [PAC] = 0.2 g L-1, [PMS] = 6.5 mmol L-1, and T = 25 degrees Celcius. It was also found that phenol degradation was significantly influenced by PMS loading, catalyst loading, phenol concentration and temperature. Surface activation of PMS and phenol adsorption played important roles in phenol degradation. Surface coverage by intermediate adsorption and structural change induced deactivation ...

Give an account of the properties and uses of phenol - GCSE Science - Marked by Teachers.comGive an account of the properties and uses of phenol - GCSE Science - Marked by Teachers.com
Introduction. 1. Give an account of the properties and uses of phenol. (1) Phenol is acidic and its conjugate base, phenoxide ion is stabilized by resonance. However, phenol is not acidic enough to liberate CO2 from phenol because an aqueous solution of carbon dioxide is a stronger acid than phenol. An aqueous solution of phenol has a pH value of 9. This means phenol reacts with NaOH but not NaHCO3. Phenol dissolves in NaOH(aq) to form sodium phenoxide, an ionic salt. (2) Phenol is corrosive and is a useful antiseptic. (3) Phenol is a colorless solid of low melting point. Its pink appearance is due to the presence of impurities. (4) When attached to a benzene ring, a hydroxyl group does not show the properties of an alcohol. The delocalization of electrons into the ring makes the -OH group inert towards replacement. On the other hand, the -OH group activates the ring toward electrophilic substitution at the ortho- and para-positions. Therefore, phenol reacts with (a) NO2+, (b) CH3+, (c) CH3CO+, ...

Phenol is one of toxic pollutants in many kinds of hypersaline industrial effluents which should be treated properly before discharged into water bodies. In this work, a halophilic strain which could utilize phenol as the sole source of carbon and energy was isolated. Based on 16S rRNA results, it was identified as a member of Citrobacter. The phenol biodegradation ability and cell growth of the strain was evaluated with the variation of initial phenol concentration and salinity. The effect of temperature and pH on phenol removal was also investigated. The results showed that the strain was capable of withstanding high phenol (up to 1,100 mg L−1) environment with varying salinity conditions (0-10% of NaCl). The optimal initial phenol concentration was 400 mg L−1, with which the average removal rates of phenol peaked at 10.8 mg L−1 h−1. The higher initial concentration of phenol could inhibit the microbial metabolism. The optimal temperature, pH and salinity were 35 °C, 6.0, and 0%, ...

Study Finds How BPA Affects Gene Expression, Anxiety; Soy Mitigates Effects | NC State News | NC State UniversityStudy Finds How BPA Affects Gene Expression, Anxiety; Soy Mitigates Effects | NC State News | NC State University
New research led by researchers at North Carolina State University shows that exposure to the chemical bisphenol A (BPA) early in life results in high levels of anxiety by causing significant gene expression changes in a specific region of the brain called the amygdala. The researchers also found that a soy-rich diet can mitigate these effects.. "We knew that BPA could cause anxiety in a variety of species, and wanted to begin to understand why and how that happens," says Dr. Heather Patisaul, an associate professor of biology at NC State and lead author of a paper describing the work. BPA is a chemical used in a wide variety of polycarbonate plastics and epoxy resins, and is used in consumer products such as some food containers.. In the study, rats were exposed to low doses of BPA during gestation, lactation (nursing) and through puberty. One group of animals was fed only soy; one group was fed a soy-free diet; one group was fed only soy and exposed to BPA; and one group was fed no soy and ...

Bisphenol A (BPA) is used in the manufacture of many products and is ubiquitous in the environment. Adverse effects of BPA on animal reproductive health have been reported, however most of the studies relied on the approaches in the assessment of conventional histology and anatomical features. The mechanistic actions of BPA are not clear. In the present study, a murine model was used to study potential effects of BPA exposure during perinatal and postnatal periods on endocrine functions of hypothalamic-pituitary-gonadal (HPG)-axis. At the hypothalamic-pituitary level, BPA exposure resulted in the up-regulation of the expression levels of KiSS-1, GnRH and FSH mRNA in both male and female pups. At the gonadal levels, BPA caused inhibition in the expressions of testicular steroidogenic enzymes and the synthesis of testosterone in the male pups. Conversely exposure to BPA resulted in a greater aromatase expression level and the synthesis of estrogen in the female pups. BPA is a weak estrogen agonist ...

Title: Polyphenols: Biological Activities, Molecular Targets, and the Effect of Methylation. VOLUME: 1 ISSUE: 3. Author(s):K. R. Landis-Piwowar and Q. P. Dou. Affiliation:Karmanos Cancer Institute, 540.01 HWCRC 4100 John R Road, Detroit, Michigan 48201-2013, USA.. Keywords:Proteasome inhibitor, molecular target, natural product, drug discovery, anticancer. Abstract: Polyphenolic compounds are widely distributed in the plant kingdom and the anticancer benefits obtained from their consumption have been studied extensively. However, polyphenols are subject to various biotransformation reactions within the human body including methylation. Likewise, naturally occurring polyphenols may contain O-methylations in place of the hydroxyls of the parent compounds. While some studies suggest that methylations can increase the bioavailability of polyphenols, other studies indicate a decrease in the anticancer benefits of methylated polyphenols. This review will focus on the cellular activities of ...

Phenols are among the highest-volume chemicals in production [ 3]. International organizations such as Agency for Toxic Substances and Disease Registry (ATSDR) [ 1] have documented phenol toxicity and recommend the monitoring of phenol exposure for groups at risk. The toxicity includes CNS depression and other symptoms such as skin burns, nausea, profuse sweating [ 1]. In exposure- and risk- evaluation, the monitoring of phenol by peripheral biomarker has several advantages over technical assessment of exposure. The urine methyl hippuric level is an acceptable peripheral biomarker for phenol exposure [ 1]. It was concluded that the phenol can be used for crude phenol exposure categorizations. Phenol is an important contamination in traffic fume [ 3]. High phenol exposure among the population living in the urban area of big city can be expected. Here, the author studied the urine phenol level among healthy subjects in urban area in Bangkok. We recommend that annual check up and monitoring for ...

  • In support of the second explanation, the p K a of the enol of acetone in water is 10.9, making it only slightly less acidic than phenol (p K a 10.0). (wikipedia.org)
Oxidation2
  • More specifically, this invention relates to the use of a cupric complex having the empirical formula CH=C11 z 2 n where X is selected from the group consisting of chlorine and bromine and n is an integer and is at least 1, as catalysts for the oxidation of phenols, and more particularly to the oxidation of phenols to either phenylene oxide polymers or to diphenoquinones. (google.es)
  • The antioxidant properties of phenols, tyrosol and hydoxytyrosol, may increase bone formation, act as free radical scavengers and prevent oxidation-induced damage to bone cells. (oliveoiltimes.com)
Cumene2
  • AdvanSix ( ASIX ) today informed its phenol customers that it is declaring force majeure as a result of shortages and delivery delays of its key raw material, cumene. (yahoo.com)
  • Phenol tar is a heavy, viscous byproduct produced in the industrial synthesis of phenol and acetone from cumene. (freepatentsonline.com)
Methyl2
  • It is shown that the fractions of heavy phenolics mostly decreased as a result of catalytic reforming, while those of light phenols, such as phenol and methyl phenols , rather increased, particularly when Al-MCM-48 was used. (thefreedictionary.com)
  • The presence of substituting methyl or methoxy groups led to lower rates compared to unsubstituted phenol or diphenyl ether. (osti.gov)
Reagents1
  • Whether to purchase isoamyl alcohol separately or mixed in with the phenol and chloroform stocks is largely an individual choice, although it is sensible to coordinate with the rest of the lab so reagents can be shared. (bionity.com)

Search1
  • NIOSHTIC-2 search results on phenol - A searchable database of worker safety and health publications, documents, grant reports, and journal articles supported in whole or in part by NIOSH. (cdc.gov)
Toxicity5
Acetone4
  • The force majeure has been declared only for phenol and will not impact shipments of other products produced at the Company's Frankford facility, including acetone and alpha-methylstyrene due to adequate inventory levels. (yahoo.com)
  • In making this conclusion, we cite the pK a of acetone enol, which is 10.9 (in comparison to phenol with a pK a of 10.0). (newworldencyclopedia.org)
  • We produce just under 1.9 million tonnes of Phenol and around 1.2 million tonnes of Acetone annually. (ineos.com)
  • In making this conclusion, one can examine the pK a of the enol of acetone , which is 10.9 in comparison to phenol with a pK a of 10.0. (wikidoc.org)
Mixtures3
Soluble5
  • The sodium salt of phenol, sodium phenoxide , is far more water-soluble. (wikipedia.org)
  • Phenol-Soluble Modulin α Peptide Toxins from Aggressive Staphylococcus aureus Induce Rapid Formation of Neutrophil Extracellular Traps through a Reactive Oxygen Species-Independent Pathway. (gu.se)
  • We show here that NET-like structures can also be formed by neutrophils after interaction with phenol-soluble modulin α (PSMα) that are cytotoxic membrane-disturbing peptides, secreted from community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA). (gu.se)
  • Phenol is naturally somewhat water-soluble, and gives a 'fuzzy' interface that is sharpened by the presence of chloroform. (bionity.com)
  • Several members of the staphylococcal phenol-soluble modulin (PSM) peptide family exhibit pronounced capacities to lyse eukaryotic cells, such as neutrophils, monocytes, and erythrocytes. (mdpi.com)
Detergents1
Disinfectants4
  • : 104 Some phenols are germicidal and are used in formulating disinfectants. (wikipedia.org)
  • Even the Environmental Protection Agency lists disinfectants that contain phenols as "corrosive and toxic. (sixwise.com)
  • So why take your chances with phenol-containing products when safer alternatives, like PerfectClean terry cloths that clean down to a microscopic level without the use of harmful disinfectants, are available? (sixwise.com)
  • And phenols are not the only dangerous ingredients in common disinfectants. (sixwise.com)
Degradation2
  • Experiments consisting of suspended cultures demonstrated the native ability of this organism to utilize phenol for its metabolic pathways enabling degradation, at levels of nearly 100 ppm within 24 hours. (scirp.org)
  • University of Minnesota Biocatalysis/Biodegradation Data- base, Phenol Family Degradation Pathway Map. (scirp.org)
Exposure6
  • Workers may be harmed from exposure to phenol.The level of harm depends upon the dose, duration, and work being done. (cdc.gov)
  • Presents a standard to prevent the adverse effects of exposure to phenol over a working lifetime. (cdc.gov)
  • People who had skin exposure to high amounts of phenol had skin burns, liver damage, dark urine, irregular heart beat, and some died. (cdc.gov)
  • Phenol has caused minor birth defects and low birth weight in animals generally at exposure levels that also were toxic to the pregnant mothers. (cdc.gov)
  • Phenol is well absorbed by all routes of exposure. (cdc.gov)
  • And if exposure to PHENOL inspires something in you to go head first into modular synths, your initial investment can be incorporated into your more ambitious modular systems. (musiciansfriend.com)
Synthesis4
  • Finding ways to effectively tailor phenol synthesis toward these different purposes could have a large impact on society," said Chang-Jun Liu, who led the team conducting this research. (redorbit.com)
  • The scientists' main finding was the discovery of three such components (called F-box proteins) that specifically recognize the first key enzyme in the series of phenol synthesis reactions. (redorbit.com)
  • For example, the set of molecular tools identified in this study might be used to increase the synthesis of certain phenols that have been shown to exhibit antioxidant properties, which could potentially enhance the health benefits of so-called functional foods. (redorbit.com)
  • Modular synthesis was the root inspiration for the PHENOL, and a cosdt and sizxe that is a fraction of the original modular systems as well as modular systems that are available today, PHENOL offers the creative potential, sound and hands-on experience of a modular synth in a sleek, compact and affordable package. (musiciansfriend.com)
Hazardous1
  • Phenol and chloroform are both hazardous and inconvenient materials, and the extraction is laborious, so in recent years many many companies now offer many alternative ways to isolate DNA. (bionity.com)
