Altered bcl-2 family expression during non-genotoxic hepatocarcinogenesis in mice. (1/44)

Dysregulation of apoptosis is an important component of multistage hepatocarcinogenesis. Members of the bcl-2 protein family are important in the regulation of apoptosis and their expression is altered in several cancers. The objectives of the present study were to determine whether the expression of members of the bcl-2 protein family are altered in mouse liver during acute treatment with non-genotoxic carcinogens and throughout non-genotoxic hepatocarcinogenesis. Acute treatment of B6C3F1 mice with phenobarbital resulted in increased levels of bcl-2 and decreased levels of bax protein, while acute treatment with WY-14,643 resulted in increased bcl-2 and BAG-1 protein in the liver. Following chronic treatment, altered hepatic foci and adenomas were classified as: small-cell, heterogeneous basophilic lesions (spontaneous or tetrachlorodibenzo-p-dioxin-induced); large-cell, homogeneous basophilic lesions (WY-14,643-induced); acidophilic lesions (phenobarbital- or chlordane-induced). Of the small-cell heterogeneous basophilic lesions, 86% of foci (31/36) and 85% of adenomas (35/41) exhibited increased bcl-2 protein levels compared with surrounding normal hepatocytes, whereas only 12.5% of foci (4/36) and 12% of adenomas (5/41) exhibited increased bcl-X(L) levels. Of the large-cell, homogenous, basophilic lesions, 100% of foci (3/3) and 90% of adenomas (9/10) expressed bcl-2 protein, whereas 100% of foci (3/3) and 80% of adenomas (8/10) exhibited increased bcl-X(L) protein levels compared with surrounding normal hepatocytes. Of the acidophilic lesions, the majority of foci (28/32, 88%) and adenomas (47/50, 94%) expressed increased bcl-X(L), whereas increased bcl-2 was observed in only 12.5% of acidophilic preneoplastic foci (4/32) and 14% of acidophilic adenomas (7/50). Of the carcinomas analyzed, 81% expressed increased bcl-2 (54/67), 78% expressed increased bcl-X(L) (52/67) and 69% expressed increased levels of both bcl-2 and bcl-X(L) (46/67). Collectively, only 8% of preneoplastic foci, 3% of adenomas and 1.5% of carcinomas did not express either bcl-2 or bcl-X(L). These results suggest that regulation of apoptotic proteins is altered during non-genotoxic carcinogenesis in mouse liver. Furthermore, there were both chemical- and lesion-specific aspects of expression of apoptotic proteins during hepatocarcinogenesis in mice.  (+info)

Two organochlorine pesticides, toxaphene and chlordane, are antagonists for estrogen-related receptor alpha-1 orphan receptor. (2/44)

Estrogen-related receptor (ERR) alpha-1 shares a high amino acid sequence homology with estrogen receptor alpha. Although estrogens are not ligands of ERR alpha-1, our recent results suggest that toxaphene and chlordane, two organochlorine pesticides with estrogen-like activity, behave as antagonists for this orphan nuclear receptor. The two compounds increased ERR alpha-1-mediated expression of the reporter enzyme beta-galactosidase in a yeast-based assay. The screen was developed by expressing the hERR alpha-1-yeast Gal 4 activation domain fusion protein in yeast cells carrying the beta-galactosidase reporter plasmid, which contains an ERR alpha-1-binding element. In transfection experiments using mammalian cell lines, such as the SK-BR-3 breast cancer cell line, the compounds were found to have an antagonist activity against ERR alpha-1-mediated expression of the reporter chloramphenicol acetyltransferase. In contrast to the findings with ERR alpha-1, the two compounds were found to slightly induce the estrogen receptor a-mediated expression of chloramphenicol acetyltransferase in SK-BR-3 cells. In a ligand-independent manner, the ERR alpha-1 activity in SK-BR-3 cells was induced 3-fold by cotransfection with the GRIP1 coactivator expression plasmid. Toxaphene was found to be capable of suppressing the GRIP1 coactivator-induced ERR alpha-1 activity in SK-BR-3 cells. In addition, a stable ERR alpha-1 expressing HepG2 hepatoma cell line was generated, and the aromatase activity in the transfected cell line was found to be twice that in the untransfected cell line. The enzyme aromatase converts androgens to estrogens, and aromatase expression in HepG2 cells is regulated in part by an ERR alpha-1-modulating promoter. A 24-h incubation of an ERR alpha-1-transfected HepG2 cell line with 10 microM toxaphene reduced its aromatase activity to the level in the untransfected cell line. Because toxaphene is not an inhibitor of aromatase, it is thought that the decrease of the aromatase activity in ERR alpha-1 transfected HepG2 cells following toxaphene treatment resulted from a suppression of the aromatase expression by toxaphene acting as the antagonist of ERR alpha-1. Toxaphene and chlordane are among the 12 persistent organic pollutants identified by the United Nations Environment Programme as requiring urgent attention. Their antagonistic effects on ERR alpha-1 should not be overlooked.  (+info)

Embryonic treatment with xenobiotics disrupts steroid hormone profiles in hatchling red-eared slider turtles (Trachemys scripta elegans). (3/44)

Many compounds in the environment capable of acting as endocrine disruptors have been assayed for their developmental effects on morphogenesis; however, few studies have addressed how such xenobiotics affect physiology. In the current study we examine the effects of three endocrine-disrupting compounds, chlordane, trans-nonachlor, and the polychlorinated biphenyl (PCB) mixture Aroclor 1242, on the steroid hormone concentrations of red-eared slider turtle (Trachemys scripta elegans) hatchlings treated in ovo. Basal steroid concentrations and steroid concentrations in response to follicle-stimulating hormone were examined in both male and female turtles treated with each of the three compounds. Treated male turtles exposed to Aroclor 1242 or chlordane exhibited significantly lower testosterone concentrations than controls, whereas chlordane-treated females had significantly lower progesterone, testosterone, and 5[alpha]-dihydrotestosterone concentrations relative to controls. The effects of these endocrine disruptors extend beyond embryonic development, altering sex-steroid physiology in exposed animals.  (+info)

trans-Nonachlor and cis-nonachlor toxicity in Sprague-Dawley rats: comparison with technical chlordane. (4/44)

cis-Nonachlor and trans-nonachlor are bioaccumulating components of the pesticide chlordane, which can be detected in various environmental biota and in humans. Existing studies have focused on the potential adverse health effects of the parent chlordane mixture. Comparable toxicity data are nonexistent for individual chlordane constituents such as trans-nonachlor, cis-nonachlor, or oxychlordane, which are among the most common chlordane-related environmental contaminants and tissue residues. In this study, rats were administered cis-nonachlor, trans-nonachlor, or technical chlordane by gavage for 28 days at doses of 0.25 to 25 mg/kg body weight. Residue analyses indicated that trans-nonachlor accumulation in adipose was greater than cis-nonachlor when rats were administered each chemical under identical conditions of dose and exposure. For all test chemicals, the major metabolite oxychlordane accumulated in adipose tissue. Adipose tissue residue levels of all test chemicals and the major metabolite were higher in female rats. The liver was a target organ in male and female rats, indicated by increased liver weight and histopathological changes consistent with microsomal enzyme induction. Hepatic changes were most pronounced in rats treated with trans-nonachlor. Elevated kidney weights and depressed organic ion transport were observed in males treated with trans-nonachlor and chlordane. Although in general, changes in target organs and clinical chemistry endpoints were similar for all 3 test chemicals, the approximate toxicity ranking from most to least toxic was trans-nonachlor > technical chlordane > cis-nonachlor.  (+info)

Role of PKC and MAP kinase in EGF- and TPA-induced connexin43 phosphorylation and inhibition of gap junction intercellular communication in rat liver epithelial cells. (5/44)

Gap junction intercellular communication (GJIC) is involved in the regulation of many cellular processes. The gap junction channels are made up of connexins and the flow of polar low molecular weight molecules through these channels is inhibited by several groups of substances, such as tumour promoters and growth factors. The phorbol ester 12-O-tetradecanoylphorbol 13-acetate (TPA), chlordane and the growth factor epidermal growth factor (EGF) are potent inhibitors of GJIC in several cell types, including the rat liver epithelial cell line IAR6.1. The induced inhibition of communication by TPA and EGF in IAR6.1 cells is associated with hyperphosphorylation of connexin43, the connexin responsible for GJIC. Two enzyme inhibitors, PD98059, a specific inhibitor of MEK kinase, and GF109203X, a selective inhibitor of protein kinase C (PKC), were used to study the signalling pathways involved in the effect of EGF and TPA on GJIC, with the following conclusions. The inhibition of cell communication in IAR6.1 cells by EGF is likely to be mediated by direct phosphorylation of connexin43 by MAP kinase. TPA blocks GJIC mainly by the direct action of PKC, but also partly through cross-talk with the MAP kinase pathway. Connexin43 hyperphosphorylation induced by TPA is, as for EGF, mediated through MAP kinase, while PKC seems to block GJIC either through other substrates or induces a type of connexin43 phosphorylation that causes no significant electrophoresis mobility shift.  (+info)

Increased concentrations of polychlorinated biphenyls, hexachlorobenzene, and chlordanes in mothers of men with testicular cancer. (6/44)

An increasing incidence of testicular cancer has been reported from several countries in the Western world during the last decades. According to current hypothesis, testicular cancer is initiated during the fetal period, and exposure to endocrine disruptors, i.e., xenoestrogens, has been of concern. In this investigation we studied the concentrations of the sum of 38 polychlorinated biphenyls (PCBs), p,p'-dichlorodiphenyl-dichloroethylene, hexachlorobenzene (HCB), and chlordanes, in 61 cases with testicular cancer and 58 age-matched controls. Furthermore, case and control mothers were also asked to participate, and 44 case mothers and 45 control mothers agreed. They were of similar age. In cases only the concentration on lipid basis of cis-nonachlordane was significantly increased, whereas case mothers showed significantly increased concentrations of the sum of PCBs, HCB, trans- and cis-nonachlordane, and the sum of chlordanes. Among case mothers the sum of PCBs yielded an odds ratio (OR) of 3.8; 95% confidence interval (CI), 1.4-10 was calculated using the median concentration for the control mothers as cutoff value. For HCB, OR = 4.4 (95% CI, 1.7-12); for trans-nonachlordane, OR = 4.1 (95% CI, 1.5-11); for cis-nonachlordane, OR = 3.1 (95% CI, 1.2-7.8); and for sum of chlordanes, OR = 1.9 (95% CI, 0.7-5.0). No consistent different risk pattern was found for seminoma or nonseminoma testicular cancer.  (+info)

The significance of insecticide-resistant strains; with special reference to pests of medical importance. (7/44)

The author discusses the meaning of insecticide resistance and the manner in which it should be detected and measured. From some recent data he gives a number of examples of measurements of resistance in mosquitos of different species in various areas. He then proceeds to a speculative discussion on the way in which insecticide resistance arises, whether it can be prevented and overcome, its importance in the past and at present, and finally its future prospects.  (+info)

Resistance of anopheline larvae to chlordane and dieldrin; field and laboratory tests on Anopheles sacharovi. (8/44)

The authors present the results of field and laboratory tests carried out to determine the susceptibility to DDT, chlordane, and dieldrin of Anopheles sacharovi larvae in the small coastal plain of Astros, Peloponnesus, where chlorinated-hydrocarbon insecticides have been extensively used for house spraying and for ground and air larviciding for over ten years. It was found that the larvae had recently developed a substantial degree of resistance to chlordane and dieldrin, but no appreciable larval resistance to DDT was observed, although the latter was by far the commonest of all the larvicides used in recent years.  (+info)

Velsicol Chemical Co. and the U.S. EPA (Environmental Protection Agency) announced October 1 an agreement that takes the termite-killing pesticide chlordane off the market for a time, possibly even forever. Most sales of chlordane are banned as of November 30, 1987, and all sales are banned as of April 30, 1988. However, the purpose of the ban is to allow the chemicals only manufacturer, Velsicol, to find new ways to apply the chemical beneath homes without contaminating indoor air. If Velsicol demonstrates they can do this, chlordane will be back on the market. This only bans sale, not use, said Jay Feldman of the National Coalition Against Misuse of Pesticides, with obvious dissatisfaction. A related chemical, heptachlor is also covered by the chlordane agreement and its sales will be phased out as well. Chlordane causes cancer in laboratory mice and is listed by the EPA as a suspected human carcinogen. It can also cause liver damage and nerve damage in exposed humans and animals. The ...
Enantioselective determination of chlordane components using chiral high-resolution gas chromatography-mass spectrometry with application to environmental samples
Chlordane is believed to bind irreversibly to DNA, leading to cell death or altered cellular function. It also affects transcription by antagonizing estrogen-related receptors. Chlordane induces hepatic cytochrome P-450, causing a large increase in the volume of the smooth endoplasmic reticulum, which results in hepatocellular enlargement and hypertrophy. Chlordane has also been shown to bind and activate retinoic acid receptor, causing various developmental defects, and inhibit alkaline phosphatases in hepatic and renal tissues.

But the Green Revolution he inspired has left behind a toxic legacy. In order to support the new breeds of plants produced, the agricultural industry produced hundreds of thousands of tons of pesticides a year through the 1950s, 60s, and onward. Unfortunately, it turned out that many of these pesticides contained/contain toxins and persistent organic pollutants. Things like lindane, aldrin, dieldrin, chlordane, heptachlor, and DDT - carcinogens, endocrine disruptors, bioaccumulators.. While, to the international societys credit, we did manage to ban the production and use of many of these chemicals through instruments like the Stockholm Convention, we are left with tens of thousands of tons of these compounds, idling in sometimes poorly stored containers worldwide. Africa alone has 50,000 tons of these now obsolete pesticides, which have occasionally been unintentionally released into communities by leaks and poor disposal practices.. ...
Photo: Ms. Lydia Louis]. Organochlorine insecticides (OCs) have long been used to control pests for decades. While many were banned in the United States during the 1970s and 1980s, some were still in use as late as 2010; moreover, OCs are still used in developing countries to control vector-borne illnesses. Although they have fallen out of use in the US, OCs are known to have long half-lives; they persist in the environment and the human body long after the initial exposure. For the past two decades, researchers have followed the health of more than 28,900 women whose spouse was a pesticide applicator to assess whether their proximity to OCs elevated their risk for various cancers.. Nearly 2,200 (more than 7.5 percent) of the women included in this study reported direct handling of OCs; 287 were diagnosed with cancer. Although most cancers were not associated with OC use, use of at least one OC increased the likelihood of developing glioma, especially among lindane users. Use of chlordane ...
Chronic treatment of rats with drugs and insecticides, such as phenobarbital, chlorcyclizine, phenylbutazone, chlordane and dichlorodiphenyltrichloroethane (DDT), stimulates the in vitro hydroxylation of progesterone and other steroids by liver microsomes and markedly decreases the central depressant effects of administered steroid hormones. The decreased central depressant effect of administered progesterone in phenobarbital-pretreated rats is associated with decreased levels of progesterone and its metabolites in the brain. The ability of liver microsomal enzyme stimulators to decrease the central depressant effects of progesterone raises the possibility that liver microsomal enzyme stimulators may also alter physiologic actions of endogenous steroids in the body.. ...

Researchers funded in part by the Canadian Cancer Society have found that exposure to certain environmental contaminants may increase the risk of non-Hodgkin lymphoma. Dr John Spinelli and his research team at the B.C. Cancer Agency collected blood samples from close to 900 BC residents - half with non-Hodgkin lymphoma (NHL) and half without. They found that the patients with NHL had much higher levels of environmental contaminants, specifically organochlorine pesticides and polychlorinated biphenyls (PCBs), in their blood than the cancer-free patients.. Individuals who had the highest total exposure to PCBs showed twice the risk for NHL compared to those with the lowest exposure. Furthermore, individuals with the highest levels of oxychlordane - a by-product of the pesticide chlordane - had 2.7 times the risk for developing NHL compared to those with the lowest exposure..

The capacity to monitor Persistent Toxic Substances (PTS), including POPs varies significantly from one country to another. For many regions, including Central America and the Caribbean, monitoring of POPs is mainly ad hoc and relies on analysis from research, accidents or evaluation of specific hot spots. This limits efforts to undertake an accurate global appraisal of PTS (UNEP 2003).. According to a UNEP global report of 2003 levels of many of the persistent pesticides in the environment of industrialized countries are declining when compared to the 1980s or 1990s. This is particularly so for pesticides such as DDT, heptachlor and chlordane. However, the report further suggests that the lack of effective alternatives to the use of persistent chemicals such as DDT in several developing countries continues to limit efforts to completely phase out the use of this chemical. DDT continues to potentially affect the health of millions of people around the world.. Persistent pesticides are still a ...
The human HazChem array includes 16 control genes and 300 environmental toxicity-related genes. In past experiments, the expression levels of these genes were altered in whole genome microarray experiments using VOCs and PAH-treated human cells. In this study, we employed the human HazChem array to determine the gene expression pattern of chemical groups. The chemical groups used in this study were PAHs, POPs, and VOCs. PAHs are one of the most widespread organic pollutants. We used chrysene and phenanthrene as examples of PAHs. POPs are chemical substances that remain in the environment, and bioaccumulate through the food chain. We utilized chlordane and toxaphene as our sample POPs. VOCs are important outdoor air pollutants. They have been shown to cause nervous system disorders through respiration and skin contact, and generally are associated with foul odors.

In the weeks before the September 27, 1962, publication, there was strong opposition to Silent Spring from the chemical industry. DuPont, a major manufacturer of DDT and 2,4-D, and Velsicol Chemical Company, the only manufacturer of chlordane and heptachlor, were among the first to respond. DuPont compiled an extensive report on the books press coverage and estimated impact on public opinion. Velsicol threatened legal action against Houghton Mifflin, and The New Yorker and Audubon Magazine unless their planned Silent Spring features were canceled. Chemical industry representatives and lobbyists lodged a range of non-specific complaints, some anonymously. Chemical companies and associated organizations produced brochures and articles promoting and defending pesticide use.

The RNFOC poses a real and present danger to all Splenda users. It is risky because the RNFOC confers a molecule with a set of super powers that wreak havoc on the human body. For example, Agent Orange, used in the U.S Army s herbicidal warfare program, is a RNFOC. Exposure can lead to Hodgkin s lymphoma and non-Hodgkins lymphoma as well as diabetes and various forms of cancer! Other shocking examples are the war gas phosgene, chlordane and lindane.[2] The RNFOC is lethal because it allows poisons to be fat soluble while rendering the natural defense mechanisms of the body helpless ...
The influence of various compounds on pulmonary tumor formation in mice after a single dose of urethan was investigated. Pretreatment by the microsomal enzyme inducers chlordane, phenobarbital, and β-naphthoflavone reduced the yield of lung tumors, but phenothiazine and diethylaminoethyl diphenyl valerate (SKF-525A) did not. None of these agents by themselves were carcinogenic to the mouse lung in a 16-week test. 3-Methylcholanthrene pretreatment induced lung tumors, the incidence of which was decreased by the subsequent injection of urethan.. Treatment with actinomycin D, puromycin, and cycloheximide, which are expected to affect macromolecular synthesis, gave the same pulmonary tumor incidence after a single dose of urethan as that noted in controls given the vehicle plus urethan.. These data demonstrate that certain enzyme inducers sharply modify the pulmonary tumor yield, but they fail to give a clue to the possible existence of an active metabolite derived from urethan, or the need for ...

Evidence pertaining to the carcinogenicity of chlordane and heptachlor/heptachlor epoxide is reviewed and evaluated. The report covers studies completed before 1985. Case reports and epidemiologic studies of pesticide applicators and pesticide manufacturing workers are reviewed, but because of methodologic limitations, these studies establish neither a positive nor a negative association between cancer and chlordane or heptachlor/heptachlor epoxide exposure. A number of independent studies of laboratory animals, however, demonstrates that chlordane and heptachlor/heptachlor epoxide cause liver cancer in mice and rats. Based on the accumulated evidence, chlordane and heptachlor/heptachlor epoxide are classified as probable human carcinogens, Group B2 using EPAs Guidelines for Carcinogen Risk Assessment. The carcinogenic potency of chlordane and heptachlor/heptachlor epoxide is estimated by fitting mathematical models to the laboratory animal data. These estimates indicate that chlordane and ...
The hypothesis that farming (1, 2, 3, 4, 5, 6, 7, 8) , agricultural practices (9) , and pesticide exposure (10, 11, 12, 13 , 22, 23, 24, 25) are associated with NHL has been tested in a number of occupational studies. Not all of the studies confirm an association (27, 28, 29) . Pesticides have diverse chemistry and biological modes of action. In addition to the active ingredients, there are emulsifiers, carriers, dispersants, and a variety of agents used to formulate liquids, granular and mists. The major chemical classes of a priori interest based on epidemiological studies (10, 11, 12, 13 , 22, 23, 24, 25) were phenoxyherbicides, organophosphorus, organochlorines, aldehydes, and carbon tetrachloride. Occupational exposure to 2,4-D, 2,4,5-T, carbaryl, chlordane, DDT, diazinon, dichlorvos, lindane, malathion, nicotine, and toxaphene has been reported to be associated with NHL. In addition, our interest focused on pesticides classified as possibly or probably carcinogenic to humans based on ...

Background: There is conflicting epidemiological evidence concerning an increase in risk of non-Hodgkins lymphoma (NHL) associated with elevated blood levels of persistent organochlorine (OC) pesticides and polychlorobiphenyls (PCBs).. Methods: We measured the concentration of 17 OC pesticides, including hexachlorobenzene (HCB), four lindane isomers (α-, β-, γ- and δ-hexachlorocyclohexane (HCH)), two chlordane species (heptachlor and oxy-chlordane), four cyclodiene insecticides (aldrin, dieldrin, endrin and mirex), six dichloro-diphenyl-trichloroethane (DDT) isomers and nine PCB congeners (PCBs 28, 52, 101, 118, 138, 153, 170, 180 and 194) in plasma samples of 377 subjects, including 174 NHL cases and 203 controls from France, Germany and Spain. The risk of NHL and its major subtypes associated with increasing blood levels of OC pesticides and PCBs was calculated using unconditional logistic regression.. Results: Risk of NHL, diffuse large B cell lymphoma (DLBCL) and chronic lymphatic ...

Industry attacks backfire. When Silent Spring appeared in 1962, the chemical industry attacked her data, her analysis, her personality, and her scientific credentials. The chemical industry sponsored articles promoting pesticide use and anonymous attacks on Carson, foreshadowing the computer trolls who now attack important environmental articles. A pro-industry review referred to her as a hysterical woman, typical of the sexist attacks.. Carson biographer Linda Lear reports in Rachel Carson: Witness for Nature, that former Secretary of Agriculture and Mormon fundamentalist Ezra Taft Benson suggested to President Dwight Eisenhower in a letter that since Carson was attractive but unmarried, she was probably a Communist.. DuPont (DDT and 2,4-D manufacturer) and Velsicol Chemical Company (chlordane and heptachlor manufacturer) - threatened lawsuits against Houghton Mifflin, The New Yorker and Audubon magazine, in attempts to suppress Silent Spring.. The chemical company American Cyanamid proved ...
BACKGROUND: We performed a cross-sectional study of associations between personal characteristics and lipid-adjusted serum concentrations of certain PCB congeners and chlorinated pesticides/metabolites among 323 pregnant primiparous women from Uppsala County (age 18-41 years) sampled 1996-1999. METHODS: Extensive personal interviews and questionnaires about personal characteristics were performed both during and after pregnancy. Concentrations of organochlorine compounds in serum lipids in late pregnancy were analysed by gas chromatography. Associations between personal characteristics and serum levels of organochlorine compounds were analysed by multiple linear regression. RESULTS: Participation rate was 82% (325 of 395 women). Serum concentrations of PCB congeners IUPAC no. 28, 52, 101, 105 and 167, and o, p-DDT and -DDE, p, p-DDT and -DDD, oxychlordane, and gamma- and alpha-HCH were in many cases below the limit of quantification (LOQ). No statistical analysis of associations with personal ...
Aliphatic amines are popular motifs in biologically relevant molecules, so chemists have myriad tools for assembling C-N bonds. Methods that make those bonds enantioselectively are particularly valuable because they can produce chiral drugs and unnatural amino acids, which are useful for studying biology. While chiral transition-metal catalysts are effective for making aromatic amines, they fall short when it comes to making aliphatic amines. These compounds tend to coordinate to the metal, poisoning the catalyst and scrambling its ability to work enantioselectively. Researchers led by Nankai Universitys Shou-Fei Zhu and Qi-Lin Zhou have managed to get around these problems by creating a reaction that uses two catalysts in tandem (Science 2019, DOI: 10.1126/science.aaw9939). The reaction (example shown) features an achiral metal catalyst-a homoscorpionate copper complex-which forms a carbene from a diazo ester. The homoscorpionate ligand protects the copper from another reactant, an aliphatic ...

Tasty roasted turkey features golden brown skin and moist meat. To ensure your turkey has both of these qualities, cover it with cheesecloth soaked with butter during the roasting process. You can soak the cheesecloth in other liquids, such a wine, to give the turkey even more flavor. The cheesecloth will seal in the juices, keeping the turkey tender and flavorful. Be sure to remove the cheesecloth in the last hour of roasting the turkey so the outside becomes crispy.. ...
As a bicyclist I can tell you Ive seen both wasp and honey bees lying dead on the street. So whatever is killing these insects, it is very disturbing to see so many. Id like to point out that the time of such sightings are in June and July , which are very hot with the Asian sun beaming down. Also honey in this country cost about $35 for about a pint. We can buy Chinese honey which if you want to live, you dont buy, at about $3 for a quart. I know it is mixed and most people will agree, and why it is allowed to be imported into this country is a crime ...

A curtal dog was one that had had its tail cut off so it could run round and round in an enclosed wheel like a hamster, providing the power to turn the spit on a roasting pig or other animal, without getting its tail caught in the spokes. I imagine the wheel was placed so a stupid dog would think that if he could just run fast enough he could get to the roasting animal and take a bite, like a horse encouraged to pull a carriage by a carrot dangled in front of his nose ...
