  1. Hoechst reportedly stalls RU-486 in U.S.

    Science.gov (United States)

    1994-05-16

    President Clinton's administration would like RU-486 to be widely available in the US, but its manufacturer has been procrastinating about introducing RU-486 in the US. President Clinton lifted the ban on it shortly after ascending to the presidency. After 13 months of negotiations, the parent company of Roussel Uclaf, Hoechst, blocked efforts. It appears to be thwarting Ru-486's manufacture in the US because it fears that antiabortion groups will boycott its other products (textiles, rug fibers, and drugs for diabetics and heart patients). Its annual sales in the US are $7 billion. In April, 1993, Roussel Uclaf said that it would transfer its patent to the Population Council. The Council agreed to perform the clinical trials required to obtain US Food and Drug Administration approval and to find a domestic manufacturer to produce RU-486. Before handing the patent over to the Population Council, Hoechst wants protection from potential product liability or losses from antiabortion protests. US Health and Human Services officials have been trying to promote progress in the negotiations between the Population Council and Hoechst. A US member of Congress has set up a subcommittee hearing to look into the delays, specifically Hoechst's role in the delays. Women's groups want US women to have access to an alternative to surgical abortion. If progress is not made soon, they intend to push the government to revoke Roussel Uclaf's patent or support development of a similar drug. They stress that Hoechst's actions, be they for economic or political reasons, have slowed medical research and have hurt women's well being. RU-486 can also be used to treat breast cancer, some brain tumors, and other diseases.

  2. Roussel-Uclaf to transfer RU 486 rights.

    1997-04-18

    On April 8, the German pharmaceutical firm Hoechst, under pressure from anti-abortion groups that were boycotting its new allergy medication, Allegra, announced the transfer of the patent rights for the abortifacient mifepristone (RU-486), from Roussel-Uclaf, its subsidiary, to Dr. Edouard Sakiz, a former executive who had been involved in the development of the drug. Dr. Sakiz has established a new company, Exelgyn, to market the drug, which, due to strict company guidelines, is currently available only in France, Sweden, and the United Kingdom. Residency requirements prevent women from traveling to these countries for treatment. Other countries desiring access to RU-486 must meet standards established by Dr. Sakiz: the government must make a formal request and provide a secure means of distribution and good follow-up care. A European manufacturer or distributor has not yet been found. In the United States, the Population Council, a nonprofit organization, has been licensed to manufacture and distribute the drug; it should be available to the general public by the end of this year. Anti-abortion groups continue to boycott all Hoechst products. The Allegra boycott was launched with an April 2 press conference; the groups, which include the National Right to Life Committee, bought full-page ads in "USA Today" and "The Washington Post."

  3. Methanex, Hoechst Celanese dissolve methanol partnership

    1993-01-01

    One of the many joint venture alliances recently announced in the petrochemical sector is ending in divorce. Hoechst Celanese Chemical (Dallas) and Methanex Corp. (Vancouver) are in the process of dissolving the partnership they had formed to restart Hoechst Celanese's methanol plant at Clear Lake, TX. Hoechst Celanese says it is actively seeking replacement partners and has several likely prospects, while Methanex is concentrating on its other ventures. Those include its just-completed acquisition of Fletcher Challenge's (Auckland, NZ) methanol business and a joint venture with American Cyanamid to convert an ammonia plant at Fortier, LA to methanol. Methanex will still be the world's largest producer of methanol. Officially, the negotiations between Methanex and Hoechst Celanese 'just broke down over the last month or so,' says Steve Yurich, operations manager for the Clear Lake plant. Market sources, however, say that Methanex found itself 'with too many irons in the fire' and pulled out before it ran into financial or perhaps even antitrust difficulties

  4. Marion Industrial Substation project

    1992-04-01

    Consumers Power, Inc. (CPI), proposes to construct a new distribution substation under the existing Bonneville Power Administration (BPA) Albay-Lebanon transmission line near the city of Albany in Linn County, Oregon. BPA is proposing to grant a new Point of Delivery to CPI at this substation. The purpose of the project is to serve the developing industrial needs in the Marion Industrial Park and on the 550 acres of nearby land within CPI's service area that are zoned for residential use. CPI prepared, and the Rural Electrification Administration (REA) has approved a Borrower's Environmental Report (BER) which addresses this action along with several other proposed projects in the CPI service area. Portions of this BER are summarized in this brief EA. BPA is preparing its own EA since Department of Energy National Environmental Policy Act (NEPA) guidelines require additional environmental concerns to be addressed than are required by REA's NEPA guidelines

  5. Marion Milner, mysticism and psychoanalysis.

    2002-02-01

    It is unusual to combine mysticism and psychoanalysis. Marion Milner, however, achieved precisely this. Through her self-analysis and analytic work with children and adults--and using as an illustration her own and others' imaginative ideas, paintings, doodles, drawings and pictures--she drew attention to the potential for health and creativity of undoing the obstacles to mystical experience of oneness with what is beyond or other than the self, which she sometimes called God, the unconscious or the id. This article seeks to explain and highlight this aspect of her contribution to, and continuing importance for, psychoanalytic theory and practice--particularly that associated with Winnicott--through detailing her early life and diary-keeping experiments, some of her psychoanalytic case histories during and after the Second World War, her work as an artist, ending with her travels and her involvement during the 1980s and 1990s with the Squiggle Foundation and British Association of Art Therapists.

  6. The radiation chemistry of Hoechst 33258 and its potential radiosensitizing analogues

    1996-01-01

    Collaborative research between Peter MacCallum Cancer Institute and The University of Melbourne is aimed to investigate the photochemistry and radiation chemistry of the halogenated analogues m-I Hoechst and o-I Hoechst (which are being developed as potential radiosensitizers). Studies were conducted on Hoechst 33258, phenyl Hoechst, m-I Hoechst and o-I Hoechst. The chemical interaction between the Hoechst analogues and the radiolysis products of water (the hydroxy radical and the aqueous electron) were investigated by saturating aqueous solutions with nitrogen or nitrous oxide (an electron scavenger) and using 2-propanol as a hydroxy radical scavenger. Hoechst 33258 was investigated at pH 5 and pH 9. Transient absorption spectra of micromolar solutions saturated with nitrogen or nitrous oxide suggest the formation of hydroxyl radical adduct(s). The rate of formation of these transient spectra was observed to be dependent on the concentration of Hoechst 33258. Phenyl Hoechst, m- I Hoechst and o-I Hoechst were studied at pH 5. Spectra again suggest the formation of hydroxy radical adducts and that both m-I Hoechst and o-I Hoechst react with aqueous electrons

  7. Hoechst and Wacker plan joint venture in PVC

    1992-01-01

    Restructuring of Europe's petrochemical industry has taken a further step with the announcement that Hoechst (Frankfurt) and Wacker Chemie (Munich) are planning a joint venture in polyvinyl chloride (PVC). The venture would include production, R ampersand D, sales and marketing, plus both companies' PVC recycling activities. However, their vinyl chloride monomer (VCM) plants, and Hoechst's Kalle PVC film business, have been left out. Erich Schnitzler, head of Hoechst's PVC business unit, does not anticipate problems with the European Community's competition directorate. We are both among the middle-sized European PVC producers, and together we would have a 9%-10% market share. Our joint venture would not limit competition. Both partners are hoping for approval from Brussels in first-quarter 1993. Hoechst has 255,000 m.t./year of PVC capacity at Gendorfand Knapsack, while Wacker has 365,000 m.t./year at Burghausen and Cologne. All the units, except Wacker's Cologne plant, are back integrated to VCM. The joint venture would buy VCM from the two parent companies and on the merchant market

    2003-01-01

    Full text: Isomers of the DNA minor groove binding ligand, iodoHoechst, have been shown to sensitise DNA to cleavage by ultraviolet type A (UVA). The DNA damage has been attributed to formation of a carbon-centred radical upon UVA induced dehalogenation of the drugs. Comparison of the efficacy of the ligands in inducing DNA single strand breaks in plasmid DNA has indicated that the ortho isomer is more efficient than the para- and meta-isomers, mainly due to a greater cross-section for dehalogenation, and to some extent from increased efficiency of DNA damage per dehalogenation event. In the present study, the efficiency of dehalogenation and cytotoxicity of the three iodoHoechst isomers has been compared in human erythroleukemic, K562 cells. The uptake of the iodoHoechst compounds in K562 nuclei has been measured, and the photoefficiency of the cellular associated dehalogenation by UVA has been established for the three isomers. The results indicate that the sensitivity to UVA mediated dehalogenation is much higher for the ortho analogue compared to the para and meta-analogues. Values of the UVA D37 doses for the ortho, para and meta isomers are 49 ± 2, 327 ± 29 and 251 ± 32 J/m 2 , respectively. Clonogenic survival assays have been used to compare the efficiency of sensitisation of cells to UVA irradiation by the analogues. The ortho analogue exhibits higher efficiency compared to the meta and para analogues. The numbers of dehalogenation events required for cell kill have been calculated from the clonogenic survival at various levels of drug uptake, and the results for the ortho, para and meta isomers are 1.2x10 4 , 3.9x10 4 and 11.6x10 4 , respectively. These results indicate that the ortho analogue is the most efficient isomer in sensitising cell kill by UVA irradiation due to both the high quantum yield for dehalogenation and the higher cytotoxic efficiency of dehalogenation events

    Molecular oxygen in living cells is distributed and consumed inhomogeneously, depending on the activity of each organelle. Therefore, tractable methods that can be used to monitor the oxygen status in each organelle are needed to understand cellular function. Here we report the design of a new oxygen-sensing probe for use in the cell nucleus. We prepared "Ru-Hoechsts", each consisting of a phosphorescent ruthenium complex linked to a Hoechst 33258 moiety, and characterized their properties as oxygen sensors. The Hoechst unit shows strong DNA-binding properties in the nucleus, and the ruthenium complex shows oxygen-dependent phosphorescence. Thus, Ru-Hoechsts accumulated in the cell nucleus and showed oxygen-dependent signals that could be monitored. Of the Ru-Hoechsts prepared in this study, Ru-Hoechst b, in which the ruthenium complex and the Hoechst unit were linked through a hexyl chain, showed the most suitable properties for monitoring the oxygen status. Ru-Hoechsts are probes with high potential for visualizing oxygen fluctuations in the nucleus. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

  15. Inhibition of radiation-induced DNA strand breaks by hoechst 33258: OH-radical scavenging and DNA radical quenching

    International Nuclear Information System (INIS)

    Adhikary, A.; Bothe, E.; Von Sonntag, C.; Adhikary, A.

    1997-01-01

    The minor-groove-binding dye Hoechst 33258 has been found to protect pBR322 DNA in aqueous solution against radiation-induced single-strand breaks (ssb). This protective effect has been assumed to be largely due to the scavenging of the strand-break-generating OH radicals by Hoechst. From D 37 values for ssb at different Hoechst concentrations the value of the OH radical scavenging constant of DNA-bound Hoechst has been estimated at k Ho/DNA = 2.7 * 10 11 dm 3 mol -1 . This unexpectedly high value has led us to study the reactions of OH radicals with Hoechst in the absence and in the presence of double-stranded calf thymus DNA (ds DNA) by pulse radiolysis, and the formation of radiation-induced ssb by low angle laser light scattering. The D 37 /D 37 0 values at different Hoechst concentrations agree with the values obtained by Martin and al. and demonstrate the protection. However, this protection cannot be explained on the basis of OH radical scavenging alone using the above rate constants. There must, in addition, be some quenching of DNA radicals. Hoechst radicals are formed in the later ms time range, i.e a long time after the disappearance of the OH radicals. This delayed Hoechst radical formation has been assigned to a a reaction of DNA radicals with Hoechst, thereby inhibiting strand breakage. In confirmation, pulse radiolysis of aqueous solution of nucleotides in the presence of Hoechst yields a similar delayed Hoechst radical formation. The data indicate that in DNA the cross-section of this quenching has a diameter of 3 to 4 base pairs per Hoechst molecule. (N.C.)

    We report a general strategy to create small-molecule fluorescent probes for the nucleus in living cells. Our strategy is based on the attachment of the DNA-binding Hoechst compound to a fluorophore of interest. Using this approach, simple fluorescein, BODIPY, and rhodamine dyes were readily converted to novel turn-on fluorescent nucleus-imaging probes.

  1. Spectroscopic Study of the Binding of Netropsin and Hoechst 33258 to Nucleic Acids

    2018-05-01

    The interaction of groove binding compounds — peptide antibiotic (polyamide) netropsin and fluorescent dye (bisbenzimidazole) Hoechst 33258 — with the double-stranded DNA and synthetic double-stranded polynucleotide poly(rA)-poly(rU) has been studied by spectrophotometry. Absorption spectra of these ligand complexes with nucleic acids have been obtained. Spectral changes at the complexation of individual ligands with the mentioned nucleic acids reveal the similarity of binding of each of these ligands with both DNA and RNA. Based on the spectroscopic measurements, the binding parameters of netropsin and Hoechst 33258 binding to DNA and poly(rA)-poly(rU) - K and n, as well as the thermodynamic parameters ΔS, ΔG, and ΔH have been determined. It was found that the binding of Hoechst 33258 to both nucleic acids is accompanied by a positive change in enthalpy, while in the case of netropsin the change in enthalpy is negative. Moreover, the contribution of entropy to the formation of the complexes is more pronounced in the case of Hoechst 33258.

    2013-05-16

    Hoechst 33258 binds with high affinity into the minor groove of AT-rich sequences of double-helical DNA. Despite extensive studies of this and analogous DNA binding molecules, there still remains uncertainty concerning the interactions when multiple ligand molecules are accommodated within close distance. Albeit not of direct concern for most biomedical applications, which are at low drug concentrations, interaction studies for higher drug binding are important as they can give fundamental insight into binding mechanisms and specificity, including drug self-stacking interactions that can provide base-sequence specificity. Using circular dichroism (CD), isothermal titration calorimetry (ITC), and proton nuclear magnetic resonance (1H NMR), we examine the binding of Hoechst 33258 to three oligonucleotide duplexes containing AT regions of different lengths: [d(CGCGAATTCGCG)]2 (A2T2), [d(CGCAAATTTGCG)]2 (A3T 3), and [d(CGAAAATTTTCG)]2 (A4T4). We find similar binding geometries in the minor groove for all oligonucleotides when the ligand-to-duplex ratio is less than 1:1. At higher ratios, a second ligand can be accommodated in the minor groove of A4T4 but not A2T2 or A3T3. We conclude that the binding of the second Hoechst to A4T4 is not cooperative and that the molecules are sitting with a small separation apart, one after the other, and not in a sandwich structure as previously proposed. © 2013 American Chemical Society.

    Hoechst 33342 is the fluorophore used routinely to measure DNA in X- and Y-chromosome-bearing mammalian sperm so they can be separated by flow sorting. A difference of artificial insemination of somewhere around a million female mammals. Offspring with obvious abnormalities are no more frequent than after insemination of unsorted sperm into cows, horses, humans, pigs, sheep, rabbits, dolphins and other mammals. There is no apparent genotoxic effect from exposure of sperm to Hoechst 33342, although information on cellular toxicity or development of embryos resulting from Hoechst 33342-stained sperm is less reassuring. Little is known about the fate of sperm-delivered Hoechst dye in the female reproductive tract or on progeny of resultant offspring.

  6. The portrayal of J. Marion Sims' controversial surgical legacy.

    2011-06-01

    In the mid 1800s Dr. J. Marion Sims reported the successful repair of vesicovaginal fistulas with a technique he developed by performing multiple operations on female slaves. A venerated physician in his time, the legacy of Dr. Sims is controversial and represents a significant chapter in the mistreatment of African-Americans by the medical establishment. This review compares the modern debate surrounding his legacy with the presentation of his operation in widely consulted urological texts and journals. A literature review was performed of medical, sociological and periodical sources (1851 to the present) regarding J. Marion Sims and vesicovaginal fistula repair. During the last several decades, while the controversy around Dr. Sims' surgical development has produced a steady stream of articles in the historical and popular literature, relatively little mention is found in standard urology textbooks or journals. With increased public attention, some have debated the removal or modification of public tributes to Dr. Sims. This move has been countered by arguments against the validity of judging a 19th century physician by modern standards. While historians, ethicists and the popular press have debated Dr. Sims' legacy, medical sources have continued to portray him unquestionably as a great figure in medical history. This division keeps the medical profession uninformed and detached from the public debate on his legacy and, thus, the larger issues of ethical treatment of surgical patients.

    2010-02-10

    The distribution of volatile constituents in ancestral genotypes of 'Marion' blackberry's pedigree was investigated over two growing seasons. Each genotype in the pedigree had a specific volatile composition. Red raspberry was dominated by norisoprenoids, lactones, and acids. 'Logan' and 'Olallie' also had a norisoprenoid dominance but at much lower concentrations. The concentration of norisoprenoids in other blackberry genotypes was significantly lower. Terpenes and furanones were predominant in wild 'Himalaya' blackberry, whereas terpenes were the major volatiles in 'Santiam'. 'Marion', a selection from 'Chehalem' and 'Olallie', contained almost all of the volatile compounds in its pedigree at moderate amount. The chiral isomeric ratios of 11 pairs of compounds were also studied. Strong chiral isomeric preference was observed for most of the chiral compounds, and each cultivar had its unique chiral isomeric distribution. An inherent pattern was observed for some volatile compounds in the 'Marion' pedigree. Raspberry and 'Logan' had a very high concentration of beta-ionone, but was reduced by half in 'Olallie' and by another half in 'Marion' as the crossing proceeded. A high content of linalool in 'Olallie' and a low content in 'Chehalem' resulted in a moderate content of linalool in their progeny 'Marion'. However, the concentration of furaneol in 'Marion' was higher than in its parents. A high content of (S)-linalool in 'Olallie' and a racemic content of (S)-,(R)-linalool in 'Chehalem' resulted in a preference for the (S)-form in 'Marion'.

    We report the development and characterization of a semiautomated method for measurement of cell proliferation in microculture using Hoechst 33342, a non-toxic specific vital stain for DNA. In this assay, fluorescence resulting from interaction of cell chromatin DNA with Hoechst 33342 dye was measured by an instrument that automatically reads the fluorescence of each well of a 96-well microtiter plate within 1 min. Each cell line examined was shown to require different Hoechst 33342 concentrations and time of incubation with the dye to attain optimum fluorescence in the assay. In all cell lines, cell chromatin-enhanced Hoechst 33342 fluorescence was shown to be a linear function of the number of cells or cell nuclei per well when optimum assay conditions were employed. Because of this linear relation, equivalent cell doubling times were calculated from growth curves based on changes in cell counts or changes in Hoechst/DNA fluorescence and the fluorimetric assay was shown to be useful for the direct assay of the influence of growth factors on cell proliferation. The fluorimetric assay also provided a means for normalizing the incorporation of tritiated thymidine ( [3H] TdR) into DNA; normalized values of DPM per fluorescence unit closely paralleled values of percent 3H-labelled nuclei when DNA synthesis was studied as a function of the concentration of rat serum in the medium. In summary, the chromatin-enhanced Hoechst 33342 fluorimetric assay provides a rapid, simple, and reproducible means for estimating cell proliferation by direct measurement of changes in cell fluorescence or by measurement of changes in the normalized incorporation of thymidine into DNA.

    Full Text Available This paper discusses Marion Halligan’s non-fiction, particularly her writing on food: Those Women who go to Hotels, Eat my Words, Cockles of the Heart, Out of the Picture, and The Taste of Memory. The focus is on how Halligan deconstructs and reconstruct a mythology of food, in a Barthesian sense, revealing the contradictions at the heart of food mythology. The texts lay bare Halligan’s own personal and at times idiosyncratic mythology of food, where food is much more that just that. Venturing into areas of autobiography, memory, travel, place and gardens, this paper discusses how Halligan’s mythologizing of food doubles up, especially in her most recent food writing, as a rethinking and celebration of suburbia, which is figured as a site where nature and culture meet, and where paradise can be regained.

    2010-03-24

    Glycosidically bound volatiles and precursors in genotypes representing the pedigree for 'Marion' blackberry were investigated over two growing seasons. The volatile precursors were isolated using a C18 solid-phase extraction column. After enzymatic hydrolysis, the released volatiles were analyzed using stir bar sorptive extraction gas chromatography-mass spectrometry (GC-MS) and direct microvial insert thermal desorption GC-MS. The most abundant volatile precursors in the genotypes were alcohols, followed by shikimic acid derivatives. High amounts of furanone glycosides were also detected, while norisoprenoids only existed in a small amount in blackberries. The volatile precursor composition in the genotypes in the 'Marion' pedigree was very similar to their free volatile distribution. 'Logan' and 'Olallie' predominantly had bound norisoprenoids. Wild 'Himalaya' predominated with terpene alcohol and furaneol glycosides, whereas 'Santiam' and 'Chehalem' contained a high level of terpene alcohol glycosides. A similar inheritance pattern was also observed for some volatile precursors in the genotypes in the 'Marion' pedigree. A high content of linalool, hydroxylinalool, and alpha-ionol glycosides in 'Olallie' and a low content in 'Chehalem' resulted in a moderate level in their offspring 'Marion', while a low content of (E)-linalool oxide precursor in 'Olallie' and a high content in 'Chehalem' also resulted in a moderate level in 'Marion'. However, the concentration of furaneol glycosides in 'Marion' exceeded that of its two parents.

    To observe cell membrane and nucleus in bacteria for subcellular localization. FM4-64 and Hoechst were dyed that can label cell membrane and nucleus, respectively. Both dyes were used to co-stain the membranes and nucleus of eight bacterial strains ( Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, Yersinia pestis, Legionella pneumonia, Vibrio cholerae and Bacillus anthracis). E. coli was dyed with different dye concentrations and times and then observed by confocal fluorescence microscopic imaging. Fluorescence intensity of cell membrane and nucleus is affected by dye concentrations and times. The optimal conditions were determined as follows: staining cell membrane with 20 μg/mL FM4-64 for 1 min and cell nucleus with 20 μg/mL Hoechst for 20 min. Gram-negative bacteria were dyed better than gram-positive bacteria with FM4-64dye. FM4-64 and Hoechst can be used to stain membrane and nucleus in different types of bacteria. Co-staining bacterial membrane and nucleus provides the reference to observe cell structure in prokaryotes for studying subcellular localization.

    2012-07-01

    The concept of core competencies in graduate medical education was introduced by the Accreditation Council for Graduate Medical Education of the American Medical Association to semiquantitatively assess the professional performance of students, residents, practitioners, and faculty. Many aspects of the career of J. Marion Sims, MD, are exemplary of those core competencies: MEDICAL KNOWLEDGE: Author of the first American textbook related to gynecology. MEDICAL CARE: Innovator of the Sims' Vaginal Speculum, Sims' Position, Sims' Test, and vesico-/rectovaginal fistulorrhaphy; advocated abdominal exploration for penetrating wounds; performed the first cholecystostomy. PROFESSIONALISM: Served as President of the New York Academy of Medicine, the American Medical Association, and the American Gynecologic Society. INTERPERSONAL RELATIONSHIPS/COMMUNICATION: Cared for the indigent, hearthless, indentured, disenfranchised; served as consulting surgeon to the Empress Eugénie (France), the Duchess of Hamilton (Scotland), the Empress of Austria, and other royalty of the aristocratic Houses of Europe; accorded the National Order of the Legion of Honor. PRACTICE-BASED LEARNING: Introduction of silver wire sutures; adoption of the principles of asepsis/antisepsis; adoption of the principles of general anesthesia. SYSTEMS-BASED PRACTICE: Established the Woman's Hospital, New York City, New York, the predecessor of the Memorial Sloan-Kettering Center for the Treatment of Cancer and Allied Diseases; organized the Anglo-American Ambulance Corps under the patronage of Napoleon III. What led him to a life of clinical and humanitarian service? First, he was determined to succeed. His formal medical/surgical education was perhaps the best available to North Americans during that era. Second, he was courageous in experimentation and innovation, applying new developments in operative technique, asepsis/antisepsis, and general anesthesia. Third, his curiosity was not burdened by rigid

  7. Labeling Adipose-Derived Stem Cells with Hoechst 33342: Usability and Effects on Differentiation Potential and DNA Damage

    Directory of Open Access Journals (Sweden)

    P. Schendzielorz

    2016-01-01

    Full Text Available Adipose-derived stem cells (ASCs have been extensively studied in the field of stem cell research and possess numerous clinical applications. Cell labeling is an essential component of various experimental protocols and Hoechst 33342 (H33342 represents a cost-effective and easy methodology for live staining. The purpose of this study was to evaluate the labeling of rat ASCs with two different concentrations of H33342 (0.5 μg/mL and 5 μg/mL, with particular regard to usability, interference with cell properties, and potential DNA damage. Hoechst 33342 used at a low concentration of 0.5 μg/mL did not significantly affect cell proliferation, viability, or differentiation potential of the ASCs, nor did it cause any significant DNA damage as measured by the olive tail moment. High concentrations of 5 μg/mL H33342, however, impaired the proliferation and viability of the ASCs, and considerable DNA damage was observed. Undesirable colabeling of unlabeled cocultivated cells was seen in particular with higher concentrations of H33342, independent of varying washing procedures. Hence, H33342 labeling with lower concentrations represents a usable method, which does not affect the tested cell properties. However, the colabeling of adjacent cells is a drawback of the technique.

  10. Boycott threat forces French company to abandon RU486.

    Science.gov (United States)

    Dorozynski, A

    1997-04-19

    Threatened boycotts by American anti-abortion groups have forced the French pharmaceutical company Roussel-Uclaf, a subsidiary of the German company Hoechst, to stop production and distribution of mifepristone (RU-486), which the protesters call "the abortion pill." All patent rights have been transferred, without charge, to Dr. Edouard Sarkiz, one of the pill's developers. Hoechst, which had acquired Marion Pharmaceuticals to form a new group, Hoechst-Marion-Roussel, had increased its share of the US pharmaceutical market from 1% to 4% in doing so and could not tolerate a boycott. RU-486, which was discovered by Professor Etienne Baulieu, was introduced in France in 1987 as an alternative to surgical abortion. Although Hoechst, then a majority stockholder of Roussel-Uclaf, had asked the French firm to interrupt production of the pill in 1988, the French minister of health and social affairs at that time, Claude Evin, ordered production to be continued. Approximately 25% of French women seeking abortion use RU-486; it is also used in Britain, Sweden, and China (women in China must pay for the drug, while surgical abortion is free). All American firms have refused to buy the drug from Roussel-Uclaf. An offer to the World Health Organization was ignored. The American Population Council obtained the right to use RU-486 in 1993. Dr. Sarkiz has formed Exelgyn, a small nonprofit company, to produce and distribute RU-486; research into other uses for the drug will also be conducted. There has been limited research into its use as an emergency contraceptive and as a treatment for endometriosis, uterine fibroma, and breast cancer. According to Professor Baulieu, the drug could be used in treating wounds and burns because of its antiglucocorticoid and immunosuppressive properties; preliminary research by the professor indicates the drug could also possibly be used as a reversible male contraceptive because of its action on the membranes of spermatozoa. The drug's use in

    2014-01-01

    Hoechst 33342 is a bisbenzimidazole derivative with AT specific minor groove DNA binding ability. Scavenging of free radicals and stabilization of macromolecular structure resulting in reduced induction of DNA damage contributes to radioprotection afforded by the ligand. Their ability to inhibit topoisomerases I and II, which play important roles in damage response pathways including DNA repair has been shown to sensitize tumor cells in vitro and in vivo. Due to its mutagenic and clastogenic potentials, damage to vital normal tissues are a matter of concern in deploying the ligand as adjuvant in radiotherapy. Therefore, we investigated the effects of the ligand in Dalton's Lymphoma (DL) bearing Balb/c mice by studying the local tumor control and animal survival, besides damage to normal tissues like bone marrow, kidney and testis. Hoechst 33342 (10 mg/kg b wt) was administered (i.v.) 1 h before focal irradiation (10 Gy) of the tumor (∼ 500 mm 3 ) grown on the hind leg of the mice. Partial response with a growth delay of 16 days (3 x initial volume) was seen following irradiation, while a complete response (cure; tumor-free survival) was observed in 88% mice following the combined treatment (Hoechst 33342+radiation); ligand alone had no significant effect. Although the ligand induced marginal degree of chromosomal aberrations in the bone marrow, it did not enhance aberrations induced by radiation further. In testes, the proportions of diploid, haploid and hypo-haploid cells as well as resting primary spermatocytes (RPS) were not significantly altered by either. In kidney, Hoechst 33342 alone or in combination with radiation did not cause significant damage to the proximal tubules and glomeruli. These observations suggest that radiosensitization of tumor by the DNA ligand Hoechst 33342 may not be associated with enhanced toxicity to bone marrow as well as proximal normal tissues. (author)

    The complex life cycle of Plasmodium falciparum (Pf) makes it difficult to limit infections and reduce the risk of severe malaria. Improved understanding of Pf blood-stage growth and development would provide new opportunities to evaluate and interfere with successful completion of the parasite's life cycle. Cultured blood stage Pf was incubated with Hoechst 33342 (HO) and thiazole orange (TO) to stain DNA and total nucleic acids, respectively. Correlated HO and TO fluorescence emissions were then measured by flow cytometry. Complex bivariate data patterns were analyzed by manual cluster gating to quantify parasite life cycle stages. The permutations of viable staining with both reagents were tested for optimal detection of parasitized RBC (pRBC). Pf cultures were exposed to HO and TO simultaneously to achieve optimal staining of pRBC and consistent quantification of early and late stages of the replicative cycle (rings through schizonts). Staining of Pf nucleic acids allows for analysis of parasite development in the absence of fixatives, lysis, or radioactivity to enable examination of erythrocytes from parasite invasion through schizont rupture using sensitive and rapid assay procedures. Investigation of the mechanisms by which anti-malarial drugs and antibodies act against different Pf lifecycle stages will be aided by this cytometric strategy.

  19. Hoechst 33258 dye generates DNA-protein cross-links during ultraviolet light-induced photolysis of bromodeoxyuridine in replicated and repaired DNA

    Energy Technology Data Exchange (ETDEWEB)

    Guo Xicang; Morgan, W.F.; Cleaver, J.E.

    1986-08-01

    Substitution of bromodeoxyuridine for thymidine in the DNA of mammalian cells sensitizes them to a range of wavelengths of ultraviolet light. Cells are also sensitized to photochemical reactions involving dyes such as Hoechst 33258, which is used to produce differential staining of chromatids according to their bromodeoxyuridine content. Irradiation with 313 nm light of human and hamster cells containing bromodeoxyuridine in their DNA produced single-strand breaks but no DNA-protein cross-links. Irradiation with 360 nm light in the presence of Hoechst 33258 produced extensive DNA-protein cross-linkage as well as single-strand breaks. These cross-links were observed in DNA containing bromodeoxyuridine incorporated by either semiconservative or repair replication. When the protein was removed with proteinase K, bromodeoxyuridine in repair patches after irradiation by doses of ultraviolet (254 nm) light as low as 0.26 J/m/sup 2/ could readily be detected. Hoechst 33258-mediated photolysis, therefore, provides a sensitive new technique for measuring repair replication after ultraviolet light irradiation.

  20. Aerial gamma ray and magnetic survey: Marion quadrangle, Ohio. Final report

    International Nuclear Information System (INIS)

    1981-06-01

    The Marion quadrangle covers a 7200 square mile area of central Ohio located within the Midwestern Physiographic Province. Up to 5000 feet of Paleozoic strata overlie the east dipping Precambrian basement. Flat lying Quaternary glacial sediments cover most of the surface within the quadrangle. A search of available literature revealed no known uranium deposits. Ninety-nine uranium anomalies were detected and are duscussed briefly. Radiometric data appear to reflect a preference for uranium occurrences in glacial moraine tills, and a minimum likelihood of occurrence in Paleozoic bedrock. Some of the largest anomalies appear to be culturally induced and no anomaly was considered to represent a significant amount of naturally occurring uranium. The magnetic data contrast somewhat with the existing structural interpretation of the area. The generally increasng magnetic gradient from west to east is interrupted by many features whose sources may be attributed to undefined lithologic and/or structural elements in the Precambrian basement

    West, M J; Irvine, L M

    2015-02-01

    Dr James Marion Sims was born in 1813 in Lancaster County, South Carolina. It was while pioneering numerous surgical procedures in Alabama that in 1849 he achieved the outstanding landmark in medical history of successfully, and consistently, repairing vesicovaginal fistulae. Sims soon developed a reputation as a fine surgeon, with new operations and techniques, using novel surgical instruments and his innovative approaches frequently published. Moving to New York City in 1853, he further established hospitals devoted entirely to women's health. Sims was controversial, with flamboyant descriptions of self-confident success, yet they were tempered with sober reflection of failure and loss. Today we remain with the Sims speculum and Sims position, eponymous tributes to his accomplishments as the 'Father of Gynaecology'. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Digital flood-inundation maps for a 9-mile (mi) reach of the Mississinewa River from 0.75 mi upstream from the Pennsylvania Street bridge in Marion, Indiana, to 0.2 mi downstream from State Route 15 were created by the U.S. Geological Survey (USGS) in cooperation with the Indiana Office of Community and Rural Affairs. The flood inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the USGS streamgage on the Mississinewa River at Marion (station number 03326500). Near-real-time stages at this streamgage may be obtained on the Internet from the USGS National Water Information System at http://waterdata.usgs.gov/ or the National Weather Service (NWS) Advanced Hydrologic Prediction Service at http://water.weather.gov/ahps/, which also forecasts flood hydrographs at this site. Flood profiles were computed for the stream reach by means of a one-dimensional step-backwater model. The model was calibrated by using the current stage-discharge relation at the Mississinewa River streamgage, in combination with water-surface profiles from historic floods and from the current (2002) flood-insurance study for Grant County, Indiana. The hydraulic model was then used to compute seven water-surface profiles for flood stages at 1-fo (ft) intervals referenced to the streamgage datum and ranging from 10 ft, which is near bankfull, to 16 ft, which is between the water levels associated with the estimated 10- and 2-percent annual exceedance probability floods (floods with recurrence interval between 10 and 50 years) and equals the “major flood stage” as defined by the NWS. The simulated water-surface profiles were then combined with a Geographic Information System digital elevation model (derived from light detection and ranging (lidar) data having a 0.98 ft vertical accuracy and 4.9 ft

  5. The medical ethics of Dr J Marion Sims: a fresh look at the historical record.

    Vesicovaginal fistula was a catastrophic complication of childbirth among 19th century American women. The first consistently successful operation for this condition was developed by Dr J Marion Sims, an Alabama surgeon who carried out a series of experimental operations on black slave women between 1845 and 1849. Numerous modern authors have attacked Sims's medical ethics, arguing that he manipulated the institution of slavery to perform ethically unacceptable human experiments on powerless, unconsenting women. This article reviews these allegations using primary historical source material and concludes that the charges that have been made against Sims are largely without merit. Sims's modern critics have discounted the enormous suffering experienced by fistula victims, have ignored the controversies that surrounded the introduction of anaesthesia into surgical practice in the middle of the 19th century, and have consistently misrepresented the historical record in their attacks on Sims. Although enslaved African American women certainly represented a "vulnerable population" in the 19th century American South, the evidence suggests that Sims's original patients were willing participants in his surgical attempts to cure their affliction-a condition for which no other viable therapy existed at that time.

    Marion Island, located in the southern Indian Ocean, constitutes the summit of an active shield volcano. It is a small terrestrial environment where glacially abraded bedrock became exposed c x 10 kyr ago. These conditions provide an interesting possibility for the assessment of 10 Be accumulation rates and their application to soil erosion studies on the island. 10 Be concentrations were measured in precipitation, soil profiles and an Azorella selago cushion plant. The data reveal a 10 Be precipitation flux several times higher than model prediction. Estimation of the 10 Be accumulation based on the soil inventory suggests a span between 2000 and 7000 yr. This time span is not in accordance with the accepted notion that the island was covered with ice about 10,000 yr ago and suggests either removal of 10 Be from the soil profile, an overestimated Holocene 10 Be-flux or a delayed soil development history. Our results provide new data on 10 Be concentrations from the sub-Antarctic islands and contribute towards enlarging the southern-hemisphere 10 Be database.

  7. Did J. Marion Sims deliberately addict his first fistula patients to opium?

    2007-07-01

    American surgeon J. Marion Sims (1813-83) is regarded by many modern authors as a controversial figure because he carried out a series of experimental surgeries on enslaved African American women between 1846 and 1849 in an attempt to cure them of vesicovaginal fistulas, which they had all developed as a result of prolonged obstructed labor. He operated on one woman, Anarcha Westcott, thirty times before he successfully closed her fistula. Sims performed these fistula repair operations without benefit of anesthesia but gave these women substantial doses of opium afterwards. Several modern writers have alleged that Sims did this in order to addict them to the drug and thereby to enhance his control over them. This article examines the controversy surrounding Sims' use of postoperative opium in these enslaved surgical patients. The evidence suggests that although these women were probably tolerant to the doses of opium that he used, there is no evidence that he deliberately tried to addict them to this drug. Sims' use of postoperative opium appears to have been well supported by the therapeutic practices of his day, and the regimen that he used was enthusiastically supported by many contemporary surgeons.

  8. J. Marion Sims and the Vesicovaginal Fistula: Historical Understanding, Medical Ethics, and Modern Political Sensibilities.

    Wall, L Lewis

    To review the historical background surrounding the early work of Dr. J. Marion Sims, who developed the first consistently successful surgical technique for the repair of obstetric vesicovaginal fistulas by operating on a group of young, enslaved, African American women who had this condition between 1846 and 1849. Review of primary source documents on Sims and his operations, early 19th century clinical literature on the treatment of vesicovaginal fistula, the introduction of ether and chloroform anesthesia into surgical practice, and the literature on the early 19th century medical ethics pertaining to surgical innovation. The goals are to understand Sims's operations within the clinical context of the 1840s and to avoid the problems of "presentism," in which beliefs, attitudes, and practices of the 21st century are anachronistically projected backward into the early 19th century. The object is to judge Sims within the context of his time, not to hold him accountable to standards of practice which were not developed until a century after his death. A narrative of what Sims did is presented within the context of the therapeutic options available to those with fistula in the early 19th century. Review of the available material demonstrates that Sims' first fistula operations were legal, that they were carried out with express therapeutic intent for the purpose of repairing these women's injuries, that they conformed to the ethical requirements of his time, and that they were performed with the patients' knowledge, cooperation, assent, and assistance.

  9. The outlook of physician histories: J. Marion Sims and 'The Discovery of Anaesthesia'.

    2015-12-01

    The fact that doctors have a long tradition of writing medical history to interpret and direct their profession is well established. But readers (particularly modern physician readers) can also understand physician-authored histories as offering commentary and analysis of the world beyond medicine. In this essay, we offer a reading (perhaps a modern one) of J. Marion Sims's 1877 article, 'The Discovery of Anaesthesia' which exemplifies the stance of looking both inward and outward from the medical field. We begin by discussing Sims, including the complicated legacy he left as a physician. Next, we review late 19th-century history with a focus on Reconstruction. Finally, we show how the modern reader can use Sims's article both to trace the first use of ether and nitrous oxide for surgical anaesthesia and to provide a window into the 19th-century medical profession and the post-Civil War period. Through this study, we hope to show how to read both medicine and the world around it in physician histories. Published by the BMJ Publishing Group Limited.

  10. Dame Bug and her students: The science and environmental teaching of Edith Marion Patch

    Science.gov (United States)

    Bird, Mary Dickinson

    What can we learn about science teaching from a dead entomologist? And what will this learning mean in the context of our own teaching, half a century after her death? This project is an exploration of the educational ideas and practices of Edith Marion Patch (1876-1954), a pioneering entomologist, educator, and environmentalist whose research and teaching shaped science learning among farmers, children, parents, teachers, and fellow scientists from the start of her career in 1903 until her retirement from professional endeavors in 1945. Patch was one of America's first university-trained female entomologists, the first woman president of the Entomological Society of America and one of the most respected scientists of her time. She was a beloved, bestselling author of more than one hundred natural history stories and books for young learners and dozens of nature and gardening articles for adults. She was also one of the earliest environmentalists to sound an alarm about the hazards of chemical pesticides, delivering her first address on the topic in 1906, one year before Rachel Carson was born. Because of the respect she earned in every milieu in which she worked, Edith Patch was uniquely positioned to influence a wide range of learners, from fellow scientists to home gardeners, to little children. Despite her accomplishments and her renown during her lifetime, Edith Patch is little remembered today. Yet her educational work may prove to be of particular relevance for our time, in which scientific literacy and environmental stewardship take on increasing urgency. Indeed, in the current climate of educational reform, which in some aspects reproduces the inquiry-based, experiential approach advocated by Patch and other education reformers a century ago, a close examination of Patch's teaching may prove to be of particular value. This study therefore seeks to fill the gap in our pedagogical memory regarding this eminent woman, considering the copious evidence of ways

  11. Water-resources programs and hydrologic-information needs, Marion County, Indiana, 1987

    Water resources are abundant in Marion County, Indiana, and have been developed for public and industrial supply, energy generation, irrigation, and recreation. The largest water withdrawals are from surface water, and the two largest water uses are public supply and cooling water for electrical-generating plants. Water-resources programs in the county are carried out by Federal, State and local agencies to address issues of surface and groundwater availability and quality. The programs of each agency are related to the functions and goals of the agency. Although each agency has specific information needs to fulfill its functions, sometimes these needs overlap, and there are times when the same hydrologic information benefits all. Overlapping information needs and activities create opportunities for interagency coordination and cooperation. Such cooperation could lead to a savings of dollars spent on water-resources programs and could assure an improved understanding of the water resources of the county. Representatives from four agencies-- the Indiana Department of Environmental Management, the Indiana Department of Natural Resources, the Indianapolis Department of Public Works, and the U.S. Geological Survey--met four times in 1987 to describe their own water-resources programs, to identify hydrologic-information needs, and to contact other agencies with related programs. This report presents the interagency findings and is intended to further communication among water resource agencies by identifying current programs and common needs for hydrologic information. Hydrologic information needs identified by the agency representatives include more precise methods for determining the volume of water withdrawals and for determining the volume of industrial and municipal discharges to surface water. Maps of flood-prone areas need to be updated as more of the county is developed. Improved aquifer maps of the inter-till aquifers are needed, and additional observation

  16. Satellite tagging and biopsy sampling of killer whales at subantarctic Marion Island: effectiveness, immediate reactions and long-term responses.

    Directory of Open Access Journals (Sweden)

    Ryan R Reisinger

    Full Text Available Remote tissue biopsy sampling and satellite tagging are becoming widely used in large marine vertebrate studies because they allow the collection of a diverse suite of otherwise difficult-to-obtain data which are critical in understanding the ecology of these species and to their conservation and management. Researchers must carefully consider their methods not only from an animal welfare perspective, but also to ensure the scientific rigour and validity of their results. We report methods for shore-based, remote biopsy sampling and satellite tagging of killer whales Orcinus orca at Subantarctic Marion Island. The performance of these methods is critically assessed using 1 the attachment duration of low-impact minimally percutaneous satellite tags; 2 the immediate behavioural reactions of animals to biopsy sampling and satellite tagging; 3 the effect of researcher experience on biopsy sampling and satellite tagging; and 4 the mid- (1 month and long- (24 month term behavioural consequences. To study mid- and long-term behavioural changes we used multievent capture-recapture models that accommodate imperfect detection and individual heterogeneity. We made 72 biopsy sampling attempts (resulting in 32 tissue samples and 37 satellite tagging attempts (deploying 19 tags. Biopsy sampling success rates were low (43%, but tagging rates were high with improved tag designs (86%. The improved tags remained attached for 26±14 days (mean ± SD. Individuals most often showed no reaction when attempts missed (66% and a slight reaction-defined as a slight flinch, slight shake, short acceleration, or immediate dive-when hit (54%. Severe immediate reactions were never observed. Hit or miss and age-sex class were important predictors of the reaction, but the method (tag or biopsy was unimportant. Multievent trap-dependence modelling revealed considerable variation in individual sighting patterns; however, there were no significant mid- or long-term changes

  17. A bulk tungsten tile for JET: Heat flux tests in the MARION facility on the power-handling performance and validation of the thermal model

    In the frame of the ITER-like Wall (ILW) for the JET tokamak, a divertor row made of bulk tungsten material has been developed for the position where the outer strike point is located in most of the foreseen plasma configurations. In the absence of active cooling, this represents a formidable challenge when one considers the temperature reached by tungsten (T W,surf > 2000 deg. C) and the vertical gradient ∂T/∂z = 5 x 10 4 K/m. As the development is drawing to an end and most components are in production, actual 1:1 prototypes are exposed to an ion beam with a power density around 7 MW/m 2 on the plasma-facing surface. Advantage is taken of the flexibility of the MARION facility to bombard the tungsten stack under shallow angles of incidence (∼6 o ) with a powerful beam of ions and neutrals (>70 MW/m 2 on axis). The shallow angles are important, with respect to the toroidal wetted surface, for properly simulating the expected performance under actual tokamak conditions. The MARION tests have been used to validate for a few typical cases the thermal calculations that were steadily developed along with the tungsten tile and, at the same time, to gather information on the actual temperatures of individual components. The latter is an important factor to a finer estimation of the power handling capabilities.

  15. Hydrogeology, water quality, and potential for contamination of the Upper Floridan aquifer in the Silver Springs ground-water basin, central Marion County, Florida

    Science.gov (United States)

    Phelps, G.G.

    1994-01-01

    The Upper Floridan aquifer, composed of a thick sequence of very porous limestone and dolomite, is the principal source of water supply in the Silver Springs ground-water basin of central Marion County, Florida. The karstic nature of the local geology makes the aquifer susceptible to contaminants from the land surface. Contaminants can enter the aquifer by seepage through surficial deposits and through sinkholes and drainage wells. Potential contaminants include agricultural chemicals, landfill leachates and petroleum products from leaking storage tanks and accidental spills. More than 560 sites of potential contamination sources were identified in the basin in 1990. Detailed investigation of four sites were used to define hydrologic conditions at representative sites. Ground-water flow velocities determined from dye trace studies ranged from about 1 foot per hour under natural flow conditions to about 10 feet per hour under pumping conditions, which is considerably higher than velocities estimated using Darcy's equation for steady-state flow in a porous medium. Water entering the aquifer through drainage wells contained bacteria, elevated concentrations of nutrients, manganese and zinc, and in places, low concentrations of organic compounds. On the basis of results from the sampling of 34 wells in 1989 and 1990, and from the sampling of water entering the Upper Floridan aquifer through drainage wells, there has been no widespread degradation of water quality in the study area. In an area of karst, particularly one in which fracture flow is significant, evaluating the effects from contaminants is difficult and special care is required when interpolating hydrogeologic data from regional studies to a specific.

    Hoechst Marion Roussel (HMR; now Aventis Pharma) launched leflunomide (HWA-486), an immunomodulator and a disease-modifying antirheumatic drug (DMARD), for the treatment of rheumatoid arthritis (RA) in the US in late 1998 [310118]. By August 2000, the compound had been launched extensively across all of Latin America and in all major European countries [380046]. The compound is also under preclinical investigationfor the prevention of transplant rejection [279727], [304402]. In 1998, HMR filed for approvalfor RA in Europe [279727]. In September 1998, the FDA approved leflunomide for the treatment of active RA in adults and it was launched shortly thereafter [298204], [299258], [310118]. In September 1999, the EU Commission accepted the view of the Committee for Proprietary Medicinal Products, published in May 1999 [326040], [337534], and gave approval for the use of leflunomide in RA in adults [339128]. Lehman Brothers has reported that EU launch was delayed by rare side effects including pancytopenia [354434]. In August 1998, the Arthritis Advisory Committee unanimously recommended that leflunomide be contraindicatedfor pregnancy, and that a pregnancy registry should be established to monitor possible teratogenic effects of the drug [296187]. Kyorin had a licence to develop leflunomide in Japan. Product approval was scheduled for 1998 [159079], but no development has been reported since 1994. Preclinical studies in an animal model of experimental allergic encephalomyelitis (EAE) have shown leflunomide to be a powerful immunosuppressant which may have potential in diseases such as multiple sclerosis [187881]. Leflunomide is rapidly processed in vivo to its active metabolite, A-771726 (RS-61980) [202941], [253615]. In 1996, leflunomide was designated as one of HMR's nine top-priority products, serving an unmet medical need and addressing a potential market in excess of US $500 million per year [221118].

  19. Perspectivas sociais e dominação simbólica: a presença política das mulheres entre Iris Marion Young e Pierre Bourdieu

    2010-06-01

    Full Text Available O artigo trata da participação política das mulheres e de sua presença no poder político. Nessa temática, discute a tensão entre o potencial emancipacionista prometido pela incorporação de múltiplas perspectivas ao debate político e a ação reprodutora do campo. Partindo das causas que, a nosso ver, são responsáveis pela relativa ausência de mulheres dos círculos decisórios e por seu "desinteresse" pela política, discutimos as perspectivas orientadas, de uma forma ou de outra, para a solução (melhoramento dessa situação. O artigo organiza-se em três seções. Na primeira, defende-se a posição de que a via mais promissora para justificar a necessidade de presença das mulheres passa pelo entendimento de que os espaços de deliberação devem abrigar uma pluralidade de perspectivas sociais relevantes - um conceito associado, sobretudo, à obra da teórica estadunidense Iris Marion Young. Na segunda, discute-se alguns problemas desse conceito, em especial, certa ingenuidade que marca um ideal dele derivado: a geração de um espaço plural de discussão e de tomada de decisão em função da adoção de cotas eleitorais. Utiliza-se o conceito de "campo", extraído da obra de Pierre Bourdieu, para depurar as idéias de Young dessa ingenuidade. Na terceira seção, introduz-se um elemento adicional: a distinção, apresentada por Nancy Fraser, entre "políticas afirmativas" e "políticas transformadoras". Conclui-se, de forma preliminar, com um balanço dos limites e das potencialidades de uma política baseada na defesa da ampliação da presença de "perspectivas sociais".

    1992-04-15

    A grant for $10 million has boosted the efforts of the Feminist majority Foundation, a Boston activist group committed to bringing RU-486 into the US. The group is planning to research the corporate structure of Hoechst, A.G., the owner of Roussel-Uclaf, and that of its US subsidiary Hoechst Celanese Corporation of Somerville, NJ. Ultimate strategies may include a boycott of Hoechst products in the US, formation of a consortium of small pharmaceutical companies, or of a feminist pharmaceutical firm to research and develop RU-486 or other antiprogestins for the US. The Hoechst Company denies any connection to Roussel-Uclaf. Meanwhile, US researchers have organized in some states to encourage research on the drug, and a bill has been introduced to force the US Food and Drug Administration to lift its ban on importation. An opposition bill to ban importation of RU-486 for any purpose including research has also been introduced by right-to-life forces. New research is underway to test the antineoplastic effects of RU-486 on breast cancer in Canada, and on meningioma in California.

    Inhale, in colaboration with Pfizer and Aventis Pharma (formerly Hoechst Marion Roussel; HMR), is developing an insulin formulation utilizing its pulmonary delivery technology for macromolecules for the potential treatment of type I and II diabetes. By July 2001, the phase III program had been completed and the companies had begun to assemble data for MAA and NDA filings; however, it was already clear at this time that additional data might be required for filing. By December 2001, it had been decided that the NDA should include an increased level of controlled, long-term pulmonary safety data in diabetic patients and a major study was planned to be completed in 2002, with the NDA filed thereafter (during 2002). US-05997848 was issued to Inhale Therapeutic Systems in December 1999, and corresponds to WO-09524183, filed in February 1995. Equivalent applications have appeared to date in Australia, Brazil, Canada, China, Czech Republic, Europe, Finland, Hungary, Japan, Norway, New Zealand, Poland and South Africa. This family of applications is specific to pulmonary delivery of insulin. In February 1999, Lehman Brothers gave this inhaled insulin a 60% probability of reaching market, with a possible launch date of 2001. The analysts estimated peak sales at $3 billion in 2011. In May 2000, Aventis predicted that estimated peak sales would be in excess of $1 billion. In February 2000, Merrill Lynch expected product launch in 2002 and predicted that it would be a multibillion-dollar product. Analysts Merril Lynch predicted, in September and November 2000, that the product would be launched by 2002, with sales in that year of e75 million, rising to euro 500 million in 2004. In April 2001, Merrill Lynch predicted that filing for this drug would occur in 2001. Following the report of the potential delay in regulatory filing, issued in July 2001, Deutsche Banc Alex Brown predicted a filing would take place in the fourth quarter of 2002 and launch would take place in the first

    Full Text Available La atmósfera dadá y surreal, que se esconde en el mundo pictórico de Granell, alcanza a su conside- ración del ser humano como cuerpo, amor, sexo, erotismo, mujer, mujer-máquina, mujer-fantástica, bajo unos soportes conceptuales que fían su discurso al humor, al azar, a la ironía, a la metaironía y a un mirar voyeurista, donde el espectador debe ser siempre un cómplice, todo lo cual se refuerza con la utilización críptica del lenguaje a partir de sus títulos barrocos. The Dada and surreal atmosphere that hides in Granell’s pictorial world refers to his consideration of the human being as body, love, sex, eroticism, woman, machine-woman, fantastic-woman. His conceptual bases build the discourse on humor, chance, irony, meta-irony and on a voyeuristic look, where the spectator must always be an accomplice. All this is reinforced by a cryptic use of the language, evident in his baroque titles.

    The plant concept is based on combustion of a multitude of substitute fuels. According to the substitute fuel specifications for general entrepreneur EBARA, comminution of waste materials in a slow shredder should be sufficient, and experience so far has shown that this is indeed the case. The plant was commissioned in 2011, and the envisaged performance parameters were achieved after some initial difficulties, i.e. the envisaged volumes of waste could be combusted. The efficiency of heat generation was below expectations, however, as the integrated heat exchangers did not run at full capacity. Reconstruction of the plant is now planned with a view to optimizing the energy yield. It is expected that the energy efficiency goals will be reached in 2013. Modernisation will comprise retrofitting of a flue gas circulation system for better temperature control in the fluidized bed and for optimum energy yield. All other plant components - off-gas filters, water/steam cycle and turbine - work satisfactorily according to the planned parameters. (orig.) [German] Das Konzept der Anlage basiert auf der thermischen Verwertung einer Vielzahl von Ersatzbrennstoffen. Entsprechend der EBS-Spezifikation fuer den Generalunternehmer EBARA sollte fuer eine ausreichende Stueckgroesse eine Zerkleinerung der Abfaelle mit einem langsam laufenden Shredder ausreichen. In der bisherigen Inbetriebnahme hat sich gezeigt, dass dies grundsaetzlich von der Anlagentechnik, bis auf eine Einschraenkung, auch erreicht wird. Die Inbetriebnahme der Anlage wurde 2011 fuer den Dauerbetrieb abgeschlossen. Nach anfaenglichen Schwierigkeiten hat die Firma EBARA die vertraglichen Leistungsparameter im Bereich der Verbrennung erreicht. Die vorgesehenen EBS-Mengen koennen verbrannt werden. Bisher is allerdings die Waermeausbeute hinter den Erwartungen zurueckgeblieben, da die Einbauten in der Wirbelschicht, das sind integrierte Waermetauscher (HRC's), bisher ihre vollstaendige Leistung nicht erbracht haben. Ein entsprechender Umbau der Anlage wird derzeit geplant, um auch die Energieausbeute zu optimieren. Es wird erwartet, dass dadurch 2013 die erwartete Energieeffizienz erreicht wird. Im Rahmen des Umbauprogramms wird insbesondere die Nachruestung einer Rauchgasrezirkulation geplant, die eine verbesserte Temperaturfuehrung in der Wirbelschicht und eine optimierte Energieausbeute gewaehrleisten soll. Alle anderen Anlagenkomponenten, Abgasreinigung, Wasser-Dampf-Kreislauf und Turbine arbeiten entsprechend den geplanten Parametern zufriedenstellend. (orig.)

  20. Geologic map of the Maumee quadrangle, Searcy and Marion Counties, Arkansas

    Turner, Kenzie J.; Hudson, Mark R.

    2010-01-01

    This map summarizes the geology of the Maumee 7.5-minute quadrangle in northern Arkansas. The map area is in the Ozark plateaus region on the southern flank of the Ozark dome. The Springfield Plateau, composed of Mississippian cherty limestone, overlies the Salem Plateau, composed of Ordovician carbonate and clastic rocks, with areas of Silurian rocks in between. Erosion related to the Buffalo River and its tributaries, Tomahawk, Water, and Dry Creeks, has exposed a 1,200-ft-thick section of Mississippian, Silurian, and Ordovician rocks mildly deformed by faults and folds. An approximately 130-mile-long corridor along the Buffalo River forms the Buffalo National River that is administered by the National Park Service. McKnight (1935) mapped the geology of the Maumee quadrangle as part of a larger 1:125,000-scale map focused on understanding the lead and zinc deposits common in the area. Detailed new mapping for this study was compiled using a Geographic Information System (GIS) at 1:24,000 scale. Site location and elevation were obtained by using a Global Positioning Satellite (GPS) receiver in conjunction with a U.S. Geological Survey 7.5-minute topographic map and barometric altimeter. U.S. Geological Survey 10-m digital elevation model data were used to derive a hill-shade-relief map used along with digital orthophotographs to map ledge-forming units between field sites. Bedding attitudes were measured in drainage bottoms and on well-exposed ledges. Bedding measured at less than 2 degree dip is indicated as horizontal. Structure contours constructed for the base of the Boone Formation are constrained by field-determined elevations on both upper and lower formation contacts.

    Hudson, Mark R.; Turner, Kenzie J.

    2009-01-01

    This map summarizes the geology of the St. Joe 7.5-minute quadrangle in the Ozark Plateaus region of northern Arkansas. Geologically, the area lies on the southern flank of the Ozark dome, an uplift that exposes oldest rocks at its center in Missouri. Physiographically, the St. Joe quadrangle lies within the Springfield Plateau, a topographic surface generally held up by Mississippian cherty limestone. The quadrangle also contains isolated mountains (for example, Pilot Mountain) capped by Pennsylvanian rocks that are erosional outliers of the higher Boston Mountains plateau to the south. Tomahawk Creek, a tributary of the Buffalo River, flows through the eastern part of the map area, enhancing bedrock erosion. Exposed bedrock of this region comprises an approximately 1,300-ft-thick sequence of Ordovician, Mississippian, and Pennsylvanian carbonate and clastic sedimentary rocks that have been mildly deformed by a series of faults and folds. The geology of the St. Joe quadrangle was mapped by McKnight (1935) as part of a larger area at 1:125,000 scale. The current map confirms many features of this previous study, but it also identifies new structures and uses a revised stratigraphy. Mapping for this study was conducted by field inspection of numerous sites and was compiled as a 1:24,000-scale geographic information system (GIS) database. Locations and elevations of sites were determined with the aid of a global positioning satellite receiver and a hand-held barometric altimeter that was frequently recalibrated at points of known elevation. Hill-shade-relief and slope maps derived from a U.S. Geological Survey 10-m digital elevation model as well as U.S. Geological Survey orthophotographs from 2000 were used to help trace ledge-forming units between field traverses within the Upper Mississippian and Pennsylvanian part of the stratigraphic sequence. Strikes and dips of beds were typically measured along stream drainages or at well-exposed ledges. Beds dipping less than 2 degrees are shown as horizontal. Structure contours constructed on the base of the Boone Formation were hand drawn based on elevations of control points on both lower and upper contacts of the Boone Formation as well as other limiting information on their maximum or minimum elevations.

    The final disposal of nuclear wastes is called ''messy'' or ''wicked'' in the political science literature. The highly complicated problems are characterized by a number of features such as intra- and inter-generational aspects and ethical questions. In the case of stakeholders the differences concern ideologies, interests, merits and preferences that cause conflicts. The search for solutions is complicated due to interacting political, social, ecologic, economic and technical aspects. The concepts ''wicked problems'' and ''multi-level-governance'' are promising approaches to solve the complicated situation.

    Thirty-six tortoises (Testudo hermanni) with naturally acquired oxyurids infections were used to assess the anthelmintic efficacy of oxfendazole (Dolthene; Merial) and fenbendazole (Panacur; Hoechst Roussel Vet). Animals were randomly assigned to three groups (A, B, and C) based on sex and weight. Animals in group A (seven males and six females) were orally treated with oxfendazole at dose rate of 66 mg/kg, group B animals (nine males and eight females) were orally treated with fenbendazole at dose rate of 100 mg/kg, and group C animals (three males and three females) were not treated and served as controls. All animals were individually stabled in plexiglas boxes under controlled conditions of temperature, humidity, and light beginning 7 days pretreatment and continuing for the duration of the trial. Individual tortoises feces were examined daily by the McMaster technique and drugs efficacy was assessed by the fecal eggs count reduction (FECR) test. Both drugs showed 100% of FECR. However, oxfendazole reached this level 12 days after treatment, whereas 31 days after treatment were necessary to obtain the same stable result with fenbendazole. The two drugs were well tolerated by all the animals and no adverse reactions were observed after treatment.

Ausgangspunkt und Verbindungsglied der Beiträge ist Judith Butlers Konzept zur Performativität von Geschlecht, das in seiner Relevanz für musikwissenschaftliche Frauen- und Genderforschung diskutiert wird. Im Zentrum steht die Reflexion der musikalischen Aufführung als Aufführung performativer Akte zur Konstruktion von Geschlechteridentitäten. Über die musikwissenschaftliche Perspektive hinaus liefern die verschiedenen Studien anregende und weitreichende Impulse zur Betrachtung künstlerischer Ausdrucksformen im Prozess der soziokulturellen Konstruktion von Geschlecht und Sexualität.The volume collects different disciplinary perspectives on the performative production of gender in the areas of music, theater, and media culture. The point of departure and nexus of the contributions is Judith Butler’s concept of the performativity of gender, which is discussed in its relevance for women���s and gender research in musicology. Central is the reflection on the musical performance as a performative act for the construction of gender identities. Over and beyond the perspective of musicology, the different studies provide stimulating and broad-reaching impulses for the consideration of artistic forms of expression in the process of the sociocultural construction of gender and sexuality.

    2003-01-01

    Introgen's adenoviral p53 gene therapy [INGN 201, ADVEXIN] is in clinical development for the treatment of various cancers. The p53 tumour suppressor gene is deleted or mutated in many tumour cells and is one of the most frequently mutated genes in human tumours. INGN 201 has been shown to kill cancer cells directly. In August 2002, Introgen announced plans to file an application for INGN 201 with the European Agency for the Evaluation of Medicinal Products (EMEA) for the treatment of head and neck cancer; the European filing will be submitted simultaneously with the previously scheduled (planned for 2004) submission of a Biologics License Application (BLA) for ADVEXIN to the US FDA. On 20 February 2003, INGN 201 received orphan drug designation from the US FDA for head and neck cancer. INGN 201 is available for licensing although Introgen favours retaining partial or full rights to the therapy in the US. Introgen Therapeutics and its collaborative partner for the p53 programme, Aventis Gencell, have been developing p53 gene therapy products. The agreement was originally signed by Rhône-Poulenc Rorer's Gencell division, which became Aventis Gencell after Rhône-Poulenc Rorer merged with Hoechst Marion Roussel to form Aventis Pharma. According to the original agreement, Introgen was responsible for phase I and preclinical development in North America, while Aventis Gencell was responsible for clinical trials conducted in Europe and for clinical trials in North America beyond phase I. In April 2001, Aventis Gencell and Introgen restructured their existing collaboration agreement for p53 gene therapy products. Aventis Gencell indicated that p53 research had suffered from internal competition for resources and was pulling back from its development agreement with Introgen for p53 gene therapy products. Introgen will assume responsibility for worldwide development of all p53 programmes and will obtain exclusive worldwide commercial rights to p53-based gene therapy

    2005-01-01

    Purpose: To validate the use of the thymidine analogues as local perfusion markers in human tumors (no labeling indicates no perfusion) by comparison with the well-characterized perfusion marker Hoechst 33342. Methods and Materials: Human tumor xenografts from gliomas and head-and-neck cancers were injected with iododeoxyuridine (IdUrd) or bromodeoxyuridine (BrdUrd) and the fluorescent dye Hoechst 33342. In frozen sections, each blood vessel was scored for the presence of IdUrd/BrdUrd labeling and Hoechst in surrounding cells. The percentage of analogue-negative vessels was compared with the fraction of Hoechst-negative vessels. Collocalization of the two markers was also scored. Results: We found considerable intertumor variation in the fraction of perfused vessels, measured by analogue labeling, both in the human tumor xenografts and in a series of tumor biopsies from head-and-neck cancer patients. There was a significant correlation between the Hoechst-negative and IdUrd/BrdUrd-negative vessels in the xenografts (r 85, p = 0.0004), despite some mismatches on a per-vessel basis. Conclusions: Thymidine analogues can be successfully used to rank tumors according to their fraction of perfused vessels. Whether this fraction correlates with the extent of acute hypoxia needs further confirmation

    We construct the exponentials of the Liouville field with continuous powers within the operator approach. Their chiral decomposition is realized using the explicit Coulomb-gas operators we introduced earlier. From the quantum group viewpoint, they are related to semi-infinite highest- or lowest-weight representations with continuous spins. The Liouville field itself is defined, and the canonical commutation relations are verified, as well as the validity of the quantum Liouville field equations. In a second part, both screening charges are considered. The braiding of the chiral components is derived and shown to agree with an ansatz of a parallel paper of Gervais and Roussel. ((orig.))

  10. Cellular uptake, nuclear localization and cytotoxicity of 125I-labelled DNA minor groove binding ligands in K562, human erythroleukaemia cells

    International Nuclear Information System (INIS)

    Karagiannis, T.C.; Lobachevsky, P.N.; Martin, R.F.

    2000-01-01

    Full text: Iodine-125 decays by orbital electron capture and internal conversion resulting in the emission of numerous Auger electrons which produce a highly localised radiochemical damage in the immediate vicinity of the site of decay. Given the requirement to deliver 125 I to the nuclear DNA, a minor groove binding bibenzimidazole, 125 I-iodoHoechst 33258 was investigated. It has been noted that this analogue may be prone to de-iodination in vitro and in vivo, given the presence of an orthoiodophenol moiety which is analogous to that in thyroxins. Therefore, an 125 I -iodoHoechst analogue without the hydroxyl group was also studied. The 125 I -iodoHoechst 33258 analogue was prepared by direct iodination of Hoechst 33258 and 125 I iodoHoechst was prepared by demetallation of a trimethylstannyl precursor. DNA binding studies indicated that both iodo-analogues bind to calf thymus DNA, K D = 89 ± 30nM, n = 0.018 bp - 1 for iodoHoechst 33258 and K D = 121 ± 31nM, n = 0.024 bp -1 for iodoHoechst. Similarly, nuclear localization following incubation with 5μM of either ligand at 37 deg C was observed in K562 cells by fluorescence microscopy. Flow cytometry was used to investigate the kinetics of drug uptake and efflux in K562 cells. The results indicated that when 10 6 cells were incubated with 5μM ligand at 37 deg C, the uptake reached a plateau at approximately 43 minutes for iodoHoechst 33258 and approximately 52 minutes for iodoHoechst. Ligand efflux results indicated two-phase kinetics.

  11. Spatial relationship between tumor perfusion and endogeneous glucose distribution

    International Nuclear Information System (INIS)

    Schroeder, T.; Larrier, N.; Viglianti, B.; Rabbani, Z.N.; Peltz, C.; Vujascovic, Z.; Dewhirst, M.W.

    2003-01-01

    Earlier studies detecting glucose in tissue and solid tumors by bioluminescence imaging suggested, that glucose distribution patterns may be spatially related to functional vascularity. The purpose of this study was to evaluate this relationship by comparing glucose distribution patterns as determined by bioluminescence imaging to perfusion patterns of endogeneous Hoechst 33342 in rats bearing mammary carcinomas. R 3230 mammary carcinoma cells have been implanted subcutaneously into 7 female Fischer 344 rats. Two months post implantation, after injection of Hoechst 33342 the tumors were removed and snap frozen to conserve metabolite levels. Concomitantly, blood was sampled from the animals for analysis of glucose concentrations using a micodialysis analyzer. Cryosections of the tumors have been prepared, and every slice has been analyzed for both, Hoechst binding by fluorescence microscopy, and for glucose distribution patterns using bioluminescence imaging. In many cases vascular structures could be retrieved by the spatial pattern of glucose distribution. In some cases however, higher glucose concentrations could be found independent from Hoechst signal. On the other hand, regions of high Hoechst signal are not necessarily correlated with high glucose concentrations. When comparing blood and tissue glucose levels, tissue glucose content as measured with bioluminescence imaging (1.9-3.5 mM) is considerably lower than blood glucose (5.6-8.0 mM), demonstrating the expected gradient from blood to tissue. This study demonstrates the feasibility of monitoring glucose gradients in relation to functional vasculature throughout the body, from blood down to tissue or tumor and further, throughout the microenvironment of the solid tumor. Glucose distribution patterns may be an important tool in perfusion studies, e. g. in detecting the direction of blood flow in ex-vivo samples or in estimating glucose consumption rates of tumor cells adjacent to or in between perfused

He developed abdominal pain and jaundice 48 days after initiating montelukast therapy. His liver tests showed an increase in serum total bilirubin, conjugated bilirubin, aspartate aminotranferase, alanine aminotranferase, and alkaline phosphatase. The patient was evaluated for possible non-drug related liver injury. Montelukast was discontinued suspecting montelukast induced hepatocellular liver injury. Liver tests began to improve and returned to normal 55 days after drug cessation. Causality of this adverse drug reaction by the Council for International Organizations of Medical Sciences or Roussel Uclaf Causality Assessment Method (CIOMS or RUCAM and Naranjo′s algorithm was ′probable′. Liver tests should be monitored in patients receiving montelukast and any early signs of liver injury should be investigated with a high index of suspicion for drug induced liver injury.

  16. An iterative method for the canard explosion in general planar systems

    DEFF Research Database (Denmark)

    Brøns, Morten

    2013-01-01

    The canard explosion is the change of amplitude and period of a limit cycle born in a Hopf bifurcation in a very narrow parameter interval. The phenomenon is well understood in singular perturbation problems where a small parameter controls the slow/fast dynamics. However, canard explosions are a...... on the van der Pol equation, showing that the asymptotics of the method is correct, and on a templator model for a self-replicating system....... are also observed in systems where no such parameter can obviously be identied. Here we show how the iterative method of Roussel and Fraser, devised to construct regular slow manifolds, can be used to determine a canard point in a general planar system of nonlinear ODEs. We demonstrate the method...

    2012-11-01

    Sistotrema brinkmannii (Bres.) J. Erikss. (Basidiomycotina, Hydanaceae), commonly regarded as a wood decay fungus, was consistently isolated from bareroot nursery Pinus banksiana Lamb. seedlings. S. brinkmannii was found in ectomycorrhizae formed by Thelephora terrestris Ehrh., Laccaria laccata (Scop.) Cooke, and Suillus luteus (L.) Roussel. In pure culture combinations with sterile P. banksiana and Populus tremuloides Michx. seedlings, S. brinkmannii colonized root cortical cells while not killing seedlings. Colonization by S. brinkmannii appeared to be intracellular but typical endo- or ectomycorrhizae were not formed. The fungus did not decay roots, although it was shown to produce cellulase in enzyme tests. Results suggest a unique association between S. brinkmannii and seedling roots that is neither mycorrhizal nor detrimental; its exact function remains to be elucidated.

    Soil metal pollution can trigger evolutionary adaptation in soil-borne organisms. An in vitro screening test showed cadmium adaptation in populations of Suillus luteus (L.: Fr.) Roussel, an ectomycorrhizal fungus of pine trees. Cadmium stress was subsequently investigated in Scots pine (Pinus sylvestris L.) seedlings inoculated with a Cd-tolerant S. luteus, isolated from a heavy metal contaminated site, and compared to plants inoculated with a Cd-sensitive isolate from a non-polluted area. A dose-response experiment with mycorrhizal pines showed better plant protection by a Cd-adapted fungus: more fungal biomass and a higher nutrient uptake at high Cd exposure. In addition, less Cd was transferred to aboveground plant parts. Because of the key role of the ectomycorrhizal symbiosis for tree fitness, the evolution of Cd tolerance in an ectomycorrhizal partner such as S. luteus can be of major importance for the establishment of pine forests on Cd-contaminated soils.

    Two magnets (no.'s 6 and 19)and a bus bar connection in the PS were found to be faulty during high-voltage tests at the end of the accelerator shutdown. A five-week repair schedule was quickly devised. A team of mechanics, technicians and engineers worked at full speed to replace the faulty magnets, succeeding in limiting the delay of the accelerators' spring start-up to two weeks. Pictured here are members of the PS team with the replacement no. 6 magnet.

    2016-10-01

    Full Text Available Resumen:La obra de César Aira es una reflexión sobre el proceso creativo. Las máquinas y procedimientos no solo son metáforas de ello; más que novelas, se proponen formas de novelar: procedimientos que, operando como máquinas, combinan elementos variopintos. Siguiendo los pasos de Raymond Roussel, al elegir un procedimiento el escritor se libera de sí mismo y de sus propias invenciones. Con premisas afines a las de Marcel Duchamp, las novelas de Aira se presentan como ‘máquinas solteras’: artefactos inútiles e intrincados, únicos e irrepetibles. El papel del artista es crear máquinas que hagan las obras por él. El lector recibe más que obras abiertas: las novelas son manuales de instrucciones.AbstractCésar Aira’s oeuvre is a constant reflection on the creative process. Machines and procedures are not only seen as metaphors that deal with this process; the very texts are not simply novels, but rather ways of composing novels: they design procedures that work like machines in order to combine different elements and produce new works. Following the steps of Raymond Roussel, if artists use a mechanical procedure, it will free them from their own inventions and personality; thus, chance and machinations allow the artist to discover something new. Following premises close to the ones of Marcel Duchamp, César Aira’s novels are presented as machines célibataires: useless, intricate and unique artifacts. Artists’ role is to create machines that do the work for them. The reader, then, faces more than an open work: these novels are instruction manuals.

  3. [Population Council responsible for RU486 clinical trials in USA].

    Science.gov (United States)

    Aguillaume, C J

    1993-04-01

    As a result of the sudden political change that came with the Clinton Administration, RU-486's manufacturer, Roussel-Uclaf, and the Population Council agreed on April 20, 1992, on the manufacture and distribution of RU-486 in the US. In the US, there are less than 1.6 million induced abortions annually. From now on, US women will be able to have a choice between medical and surgical abortion. The Population Council and Roussel-Uclaf have had a contract since 1982. The Council is solely responsible for the phase 2 clinical trial of RU-486 in the US and other countries. It must present to the US Food and Drug Administration (FDA) an amendment allowing it to begin phase 3 clinical trials. The Council will also lead the US medical facilities in this study. It will identify partners for future production of RU-486 and its distribution in the US. It will also submit to FDA a New Drug Application (NDA). FDA will review the scientific literature on RU-486 and evaluate all data submitted by the Population Council. There are still obstacles to be surmounted. The Population Council must demonstrate good judgment when selecting the criteria for choosing a pharmaceutical firm before a Technical Committee which will be part of a group of players promoting women's health, scientific experts, and other interested parties. It must find the necessary funds to conduct the clinical trials and prepare the NDA. Phase 3 clinical trials in the US must have at least 2000 women. They will test RU-486's efficacy, safety, and acceptability among women choosing medical abortion over surgical abortion. Since the Council operates in almost all countries in the world, has innovated contraceptive research and development activities, and has been endorsed by the UN, product approval of RU-486 in the US will affect policy in all countries concerned about abortion.

  4. Detecting EUV transients in near real time with ALEXIS

    Energy Technology Data Exchange (ETDEWEB)

    Roussel-Dupre`, D.; Bloch, J.J.; Theiler, J.; Pfafman, T.; Beauchesne, B.

    1995-12-31

    The Array of Low Energy X-ray Imaging Sensors (ALEXIS) experiment consists of a mini-satellite containing six wide angle EUV/ultrasoft X-ray telescopes (Priedhorsky et al. 1989, and Bloch et al. 1994). Its scientific objective is to map out the sky in three narrow ({Delta}E/E {approx} 5%) bandpasses around 66, 71, and 93 eV. During each 50 second satellite rotation period the six telescopes, each with a 30{degrees} field, of:view and a spatial resolution of 0.25{degrees}, scan most of the antisolar hemisphere of the sky. The project is a collaborative effort between Los Alamos National Laboratory, Sandia National Laboratory, and the University of California-Berkeley Space Sciences Laboratory. It is controlled entirely from a small ground station located at Los Alamos. The mission was launched on a Pegasus Air Launched Vehicle on April 25, 1993. An incident at launch delayed our ability to properly analyze the data until November of 1994. In January of 1995, we brought on line automated software to routinely carry out the transient search. After the data is downlinked from the satellite, the software processes and transforms it into sky maps that are automatically searched for new sources. The software then sends the results of these searches by e-mail to the science team within two hours of the downlink. This system has successfully detected the Cataclysmic Variables VW Hyi, U Gem and AR UMa in outburst, and has detected at least two unidentified short duration EUV transients (Roussel-Dupre et al 1995, Roussel-Dupre 1995).

  5. Comparison of commercial diagnostic kits for placental lactogen radioimmunoassay

    Pirkl, S.; Kulenda, Z.

    1976-01-01

    The biochemical laboratory compared the following diagnostic kits for HPL determination: Pharmacia (Sweden), Radiochemical Center Amersham (GB), NEN (USA), Hoechst (FRG), applying the following criteria: 1. price, 2. number of analyses for which one kit may be applied, 3. expiration time, 4. speed, i.e., time elapsed from sample delivery to report (dependent on incubation time), 5. laboriousness, 6. reproducibility, 7. compatibility of values obtained by different kits. Alcohol precipitation (Pharmacia, RCC Amersham) appeared to be the most suitable while Dextran coated charcoal (NEN) and Amberlite (Hoechst) were somewhat more complicated, and the Sorin double antibody technique (ultrafiltration and washing of precipitate on filtres was used for separation) appeared to be the most laborious technique. RCC Amersham was ranked first owing to its lower cost as compared with runner-up Pharmacia. (L.O.)

  6. Selection of viable cell subpopulations from murine tumours using FACS

    International Nuclear Information System (INIS)

    Chaplin, D.J.; Durand, R.E.; Olive, P.L.

    1985-01-01

    The authors developed a technique which enables isolation of viable tumour cells subpopulation as a function of their distance from the blood supply. The basis for this separation procedure is that the fluorochrome, Hoechst 33342, as a result of its high avidity for cellular DNA, exhibits a marked diffusion/consumption gradient when it has to pass through several cell layers. As a result intravenous injection of Hoechst 33342 into tumour bearing animals, results in a heterogeneous straining pattern within the tumour with cells close to blood vessels being brightly fluorescent while those more distant are less intensely stained. Since these differences in staining intensity persist after tumour disaggregation, cells can be sorted into subpopulations on the basis of their fluorescence intensity using a fluorescence activated cell sorter. This technique offers the unique possibility of identifying the location of those cell subpopulations resistant to treatment with either radiation or chemotherapeutic drugs

    1984-09-01

    A bibliographic research has been carried out for reprocessing techniques of irradiated thorium fuel from nuclear reactors. The Thorex/Hoechst process has been specially considered to establish a method for reprocessing thorium-uranium fuel from PWR. After a series of cold tests performed in laboratory it was possible to set the behavior of several parameters affecting the Thorex/Hoechst process. Some comments and suggestions are presented for modifications in the process flosheet conditions. A discussion is carried out for operational conditions such as the aqueous to organic flow ratio the acidity of strip and scrub solutions in the process steps for thorium and uranium recovery. The operation diagrams have been constructed using equilibrium experimental data which correspond to conditions observed in laboratory. (Author) [pt

  13. Pulse radiolysis studies on DNA-Binding radioprotectors

    International Nuclear Information System (INIS)

    Anderson, R.F.

    1996-01-01

    Full text: Hoechst 33342 and newly-synthesised analogues exhibit radioprotective activity in cultured cells and in vivo, as described in accompanying abstracts. These minor groove binding ligands bind at discreet sites in DNA, characterised by 3 to 4 consecutive AT base pairs, and DNA sequencing studies have shown focussed radioprotection at these binding sites. There is evidence that the bound ligands also confer more 'global' protection including the intervening DNA between the binding sites. The observed focussed radioprotection could be explained by H-atom donation from the ligand to radiation-induced carbon-centred deoxyribosyl radicals, but this mechanism is unlikely to account for the global radioprotection. We now report pulse radiolysis studies on another possible mechanism, namely reduction of transient radiation-induced oxidising species on DNA by the ligand, which is consistent with the report of reduction of G + by TMPD. Oxidation of deoxyguanosine (dG) by Br 2 - , produced by radiolysis of Br- in N 2 0-saturated solutions, in the presence of Hoechst 33342 results in the appearance of a transient ligand species which is kinetically resolvable from that obtained from direct oxidation of Hoechst 33342 by Br 2 - . A plot of reaction rate versus ligand concentration indicates that the rate constant for reduction of G + is approximately 3 x 10 8 dm 3 M -1 sec -1 . Similar experiments with DNA, rather than dG, also revealed a transient species corresponding to oxidation of the ligand, but the absolute rate of oxidation was considerably slower for the DNA-bound ligand compared to that for oxidation of the free ligand by G+. These results are clearly consistent with the proposed mechanism of radioprotection by Hoechst 33342 and its analogues, moreover, pulse radiolysis may provide a very useful endpoint for screening new analogues, as a preliminary to radiobiological evaluation

    Purpose: To investigate the factors affecting the 18 F-fluorodeoxyglucose ( 18 F-FDG) uptake in tumors at a microscopic level, by correlating it with tumor hypoxia, cellular proliferation, and blood perfusion. Methods and Materials: Nude mice bearing Dunning prostate tumors (R3327-AT) were injected with 18 F-FDG and pimonidazole, bromodeoxyuridine, and, 1 min before sacrifice, with Hoechst 33342. Selected tumor sections were imaged by phosphor plate autoradiography, while adjacent sections were used to obtain the images of the spatial distribution of Hoechst 33342, pimonidazole, and bromodeoxyuridine. The images were co-registered and analyzed on a pixel-by-pixel basis. Results: Statistical analysis of the data obtained from these tumors demonstrated that 18 F-FDG uptake was positively correlated with pimonidazole staining intensity in each data set studied. Correlation of FDG uptake with bromodeoxyuridine staining intensity was always negative. In addition, FDG uptake was always negatively correlated with the staining intensity of Hoechst 33342. Conclusions: For the Dunning prostate tumors studied, FDG uptake was always positively correlated with hypoxia and negatively correlated with both cellular proliferation and blood flow. Therefore, for the tumor model studied, higher FDG uptake is indicative of tumor hypoxia, but neither blood flow nor cellular proliferation

    A mathematical model for the pharmacokinetics of Hoechst 33342 following administration into a culture medium containing a population of transfected cells (HEK293 hBCRP) with a potent breast cancer resistance protein inhibitor, Fumitremorgin C (FTC), present is described. FTC is reported to almost completely annul resistance mediated by BCRP in vitro. This non-linear compartmental model has seven macroscopic sub-units, with 14 rate parameters. It describes the relationship between the concentration of Hoechst 33342 and FTC, initially spiked in the medium, and the observed change in fluorescence due to Hoechst 33342 binding to DNA. Structural identifiability analysis has been performed using two methods, one based on the similarity transformation/exhaustive modelling approach and the other based on the differential algebra approach. The analyses demonstrated that all models derived are uniquely identifiable for the experiments/observations available. A kinetic modelling software package, namely FACSIMILE (MPCA Software, UK), was used for parameter fitting and to obtain numerical solutions for the system equations. Model fits gave very good agreement with in vitro data provided by AstraZeneca across a variety of experimental scenarios. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

  18. A rapid fluorometric method for semiautomated determination of cytotoxicity and cellular proliferation of human tumor cell lines in microculture.

    Larsson, R; Nygren, P

    1989-01-01

    A fluorometric method for the determination of cellular growth and cytotoxicity of human tumor cell lines in 96-well microculture plates is described. The assay is based on the combined use of the DNA-binding dye Hoechst 33342 and the fluorogenic substrate fluorescein diacetate (FDA). Hoechst 33342 undergoes a dramatic enhancement of fluorescence when specifically intercalated with cellular DNA, whereas the FDA fluorescence is dependent on cellular hydrolysis of the non-fluorescent substrate into its fluorescent product. Fluorescence from both dyes was linearly related to the density of freshly seeded cells (6 x 10(3)-1 x 10(5)/well) and correlated well with physical cell count of cells under normal culture conditions as well as in response to the vinca alkaloid vincristine. However, the amount of FDA fluorescence produces and retained by the cultures was clearly dependent on the fraction of intact and viable cells, whereas the fluorescence reported by Hoechst 33342 was not. The assay was found to be simple, reliable and many samples could be analysed in a short period of time with minimal waste of cells and biological reagents. Apart from giving an estimate of cell density, the protocol described also provides a separate index of viability which in certain situations may be of importance for distinguishing between cytocidal and cytostatic drug actions. The method may be well suited for several applications, including the large scale screening for antitumor activity of compounds with potential cytocidal or cytostatic actions.

  19. Comparison between morphological and staining characteristics of live and dead eggs of Schistosoma mansoni

    2006-10-01

    Full Text Available Schistosoma mansoni eggs are classified, according to morphological characteristics, as follows: viable mature and immature eggs; dead mature and immature eggs, shells and granulomas. The scope of this study was to compare the staining characteristics of different morphological types of eggs in the presence of fluorescent labels and vital dyes, aiming at differentiating live and dead eggs. The eggs were obtained from the intestines of infected mice, and put into saline 0.85%. The fluorescent labels were Hoechst 33258 and Acridine Orange + Ethidium Bromide and vital dyes (Trypan Blue 0.4% and Neutral Red 1%. When labelled with the probe Hoechst 33258, some immature eggs, morphologically considered viable, presented fluorescence (a staining characteristic detected only in dead eggs; mature eggs did not present fluorescence, and the other types of dead eggs, morphologically defined, showed fluorescence. As far as Acridine Orange + Ethidium Bromide are concerned, either the eggs considered to be live, or the dead ones, presented staining with green color, and only the hatched and motionless miracidium was stained with an orange color. Trypan Blue was not able to stain the eggs, considered to be dead but only dead miracidia which had emerged out of the shell. Neutral Red stained both live and dead eggs. Only the fluorescent Hoechst 33258 can be considered a useful tool for differentiation between dead and live eggs.

    There is a great need for the development of therapeutic strategies that can target biomolecules to damaged myocardium. Necrosis of myocardium during a myocardial infarction (MI) is characterized by extracellular release of DNA, which can serve as a potential target for ischemic tissue. Hoechst, a histological stain that binds to double-stranded DNA can be conjugated to a variety of molecules. Insulin-like growth factor-1 (IGF-1), a small protein/polypeptide with a short circulating-half life is cardioprotective following MI but its clinical use is limited by poor delivery, as intra-myocardial injections have poor retention and chronic systemic presence has adverse side effects. Here, we present a novel delivery vehicle for IGF-1, via its conjugation to Hoechst for targeting infarcted tissue. Using a mouse model of ischemia-reperfusion, we demonstrate that intravenous delivery of Hoechst-IGF-1 results in activation of Akt, a downstream target of IGF-1 and protects from cardiac fibrosis and dysfunction following MI.

    Iodinated DNA minor groove binding bibenzimidazoles represent a unique class of UVA photosensitizer and their extreme photopotency has been previously characterized. Earlier studies have included a comparison of three isomers, referred to as ortho-, meta- and para-iodoHoechst, which differ only in the location of the iodine substituent in the phenyl ring of the bibenzimidazole. DNA breakage and clonogenic survival studies in human erythroleukemic K562 cells have highlighted the higher photo-efficiency of the ortho-isomer (subsequently designated UV(A)Sens) compared to the meta- and para-isomers. In this study, the aim was to compare the induction and repair of DNA double-strand breaks induced by the three isomers in K562 cells. Further, we examined the effects of the prototypical broad-spectrum histone deacetylase inhibitor, Trichostatin A, on ortho-iodoHoechst/UVA-induced double-strand breaks in K562 cells. Using γH2AX as a molecular marker of the DNA lesions, our findings indicate a disparity in the induction and particularly, in the repair kinetics of double-strand breaks for the three isomers. The accumulation of γH2AX foci induced by the meta- and para-isomers returned to background levels within 24 and 48 h, respectively; the number of γH2AX foci induced by ortho-iodoHoechst remained elevated even after incubation for 96 h post-irradiation. These findings provide further evidence that the extreme photopotency of ortho-iodoHoechst is due to not only to the high quantum yield of dehalogenation, but also to the severity of the DNA lesions which are not readily repaired. Finally, our findings which indicate that Trichostatin A has a remarkable potentiating effect on ortho-iodoHoechst/UVA-induced DNA lesions are encouraging, particularly in the context of cutaneous T-cell lymphoma, for which a histone deacetylase inhibitor is already approved for therapy. This finding prompts further evaluation of the potential of combination therapies. Copyright © 2011

    Large image datasets acquired on automated microscopes typically have some fraction of low quality, out-of-focus images, despite the use of hardware autofocus systems. Identification of these images using automated image analysis with high accuracy is important for obtaining a clean, unbiased image dataset. Complicating this task is the fact that image focus quality is only well-defined in foreground regions of images, and as a result, most previous approaches only enable a computation of the relative difference in quality between two or more images, rather than an absolute measure of quality. We present a deep neural network model capable of predicting an absolute measure of image focus on a single image in isolation, without any user-specified parameters. The model operates at the image-patch level, and also outputs a measure of prediction certainty, enabling interpretable predictions. The model was trained on only 384 in-focus Hoechst (nuclei) stain images of U2OS cells, which were synthetically defocused to one of 11 absolute defocus levels during training. The trained model can generalize on previously unseen real Hoechst stain images, identifying the absolute image focus to within one defocus level (approximately 3 pixel blur diameter difference) with 95% accuracy. On a simpler binary in/out-of-focus classification task, the trained model outperforms previous approaches on both Hoechst and Phalloidin (actin) stain images (F-scores of 0.89 and 0.86, respectively over 0.84 and 0.83), despite only having been presented Hoechst stain images during training. Lastly, we observe qualitatively that the model generalizes to two additional stains, Hoechst and Tubulin, of an unseen cell type (Human MCF-7) acquired on a different instrument. Our deep neural network enables classification of out-of-focus microscope images with both higher accuracy and greater precision than previous approaches via interpretable patch-level focus and certainty predictions.

    2018-03-01

    Drawing on ethnographic and historical research, this article illuminates the limitations of the Uruguayan domestic violence services system. In spite of how advocates in Uruguay successfully used a human rights platform to secure legislation and services, this system now faces significant critique. Using Iris Marion Young's work on the "logic of masculinist protection" and historical parallels in Uruguay's welfare system, I discuss how a paternalistic approach may be to blame. I highlight how this paternalism contributes to the paternalism that problematically underlies gendered violence-reinforcing rather than addressing oppressive ideologies and structures that impede improving conditions for women.

    Joshi, H; Lubell, H; Mouly, J

    1975-04-01

    The city of Abidjan in the Ivory Coast has grown physically, economically, and demographically at rates exceeding all reasonable expectation. Yet, as in many other development nations, the employment generated by Abidjan's rapid economic expansion has failed to keep pace with the increase in working population it has attracted. Consequently, economic success has been accompanied by a variety of social strains. Some of these have been discussed in earlier issues of the "International Labour Review" by Louis Roussel. This discussion expands on Roussel's earlier treatment by focusing more specifically on several facets of the urban employment problem created by the rapid growth of Abidjan. Attention is directed to labor supply and employment, factors affecting migration, foreign Africans in the Ivory Coast labor force; the urban informal sector; urban infrastructure and development; social problems of population pressure; employment policy options (current government policies and other policy options); and general issues and policy alternatives (motivations for rural urban migration, smaller urban centers as alternative growth poles, and distributing the gains from development). Several essential features of the employment problem stem from the rural urban distribution of the workforce. The rural labor force, including temporary seasonal workers from the savannah countries to the north, remains more or less in balance with increasing rural employment opportunities, since the migration of Ivory Coast nationals to the cities is balanced by the inflow of foreign workers. In contrast, the influx of migrants into urban areas has led to a more rapid increase in the urban labor force than in urban employment, with a consequent rise in unemployment. In 1970 the Abidjan rate of open unemployment was probably around 20%. At this time, most people's idea of a desirable job is one in the formal sector of the urban economy. If there is to be any hope of an eventual balance between

    Non-pathogenic spore-forming Clostridia are of increasing interest due to their application in biogas production and their capability to spoil different food products. The life cycle for Clostridium includes a spore stage that can assist in survival under environmentally stressful conditions, such as extremes of temperature or pH. Due to their size, spores can be investigated by a range of microscopic techniques, many of which involve sample pre-treatment. We have developed a quick, simple and non-destructive fluorescent staining procedure that allows a clear differentiation between spores and vegetative cells and effectively stains spores, allowing recovery and tracking in subsequent experiments. Hoechst 34580, Propidium iodide and wheat germ agglutinin WGA 488 were used in combination to stain four strains of Clostridia at different life cycle stages. Staining was conducted without drying the sample, preventing changes induced by dehydration and cells observed by confocal laser scanner microscopy or using a super-resolution microscope equipped with a 3D-structured illumination module. Dual staining with Hoechst/Propidium iodide differentiated spores from vegetative cells, provided information on the viability of cells and was successfully applied to follow spore production induced by heating. Super-resolution microscopy of spores probed by Hoechst 34580 also allowed chromatin to be visualised. Direct staining of a cheese specimen using Nile Red and Fast Green allowed in situ observation of spores within the cheese and their position within the cheese matrix. The proposed staining method has broad applicability and can potentially be applied to follow Clostridium spore behaviour in a range of different environments. Copyright © 2018 Elsevier Ltd.

  20. Flow Cytometry of the Side Population: Tips & Tricks

    Directory of Open Access Journals (Sweden)

    Irene Sales-Pardo

    2006-01-01

    Full Text Available Background: The Side Population (SP has become an important hallmark for the definition of the stem cell compartment, especially in the detection of these cells and in their physical isolation by fluorescence-activated cell sorting (FACS. SP cells are CD34neg and were discovered using ultraviolet excitation based on the efflux of Hoechst 33342 (Ho342. Although the method works as originally described, we believe that this method is difficult for most investigators. First, because the ability to discriminate SP cells is based on the differential retention of Ho342 during a functional assay; second, because of the difficulties in setting the right experimental and acquisition conditions; and third, because the analysis of the acquired data requires an extensive expertise on flow cytometry to accurately detect the SP events. Methods: First of all and mainly for the SP application, the laser beam paths were exhaustively checked to ensure the lowest coefficients of variation. Blood suspensions were prepared by erythrocyte lysis with ammonium chloride and hematopoietic cells were labeled with Ho342. Results: The Ho342 concentration and the staining procedure are critical for the optimal resolution of the SP cells. Although UV laser alignment is very important to resolve the dim tail that outlines the SP, the problem with Ho342 excitation is not the Hoechst Blue emission, but rather the Hoechst Red's (because of the weak emission. Conclusions: Each laboratory must establish its own expected ranges based on its instrument and results may vary slightly due to instrument differences such as the narrowness of the band pass filters, laser power, laser emission wavelength, nozzle type, differential of pressure, light collection system (cuvette versus jet-in-air and beam shaping optics.

  1. Design of a Bioactive Small Molecule that Targets the Myotonic Dystrophy Type 1 RNA Via an RNA Motif-Ligand Database & Chemical Similarity Searching

    Myotonic dystrophy type 1 (DM1) is a triplet repeating disorder caused by expanded CTG repeats in the 3′ untranslated region of the dystrophia myotonica protein kinase (DMPK) gene. The transcribed repeats fold into an RNA hairpin with multiple copies of a 5′CUG/3′GUC motif that binds the RNA splicing regulator muscleblind-like 1 protein (MBNL1). Sequestration of MBNL1 by expanded r(CUG) repeats causes splicing defects in a subset of pre-mRNAs including the insulin receptor, the muscle-specific chloride ion channel, Sarco(endo)plasmic reticulum Ca2+ ATPase 1 (Serca1/Atp2a1), and cardiac troponin T (cTNT). Based on these observations, the development of small molecule ligands that target specifically expanded DM1 repeats could serve as therapeutics. In the present study, computational screening was employed to improve the efficacy of pentamidine and Hoechst 33258 ligands that have been shown previously to target the DM1 triplet repeat. A series of inhibitors of the RNA-protein complex with low micromolar IC50’s, which are >20-fold more potent than the query compounds, were identified. Importantly, a bis-benzimidazole identified from the Hoechst query improves DM1-associated pre-mRNA splicing defects in cell and mouse models of DM1 (when dosed with 1 mM and 100 mg/kg, respectively). Since Hoechst 33258 was identified as a DM1 binder through analysis of an RNA motif-ligand database, these studies suggest that lead ligands targeting RNA with improved biological activity can be identified by using a synergistic approach that combines analysis of known RNA-ligand interactions with virtual screening.

    The purpose of this study was to assess sperm quality in extended boar semen during in vitro storage in order to determine which extender should be used and how long boar semen can be stored. Freshly ejaculated boar semen was diluted with equal volumes of Beltsville thaw solution (BTS), Androhep, KIEV or Zorlesco extenders and stored at 17 degrees C for up to 15 days. Sperm quality was evaluated by examining viability using SYBR-14/PI and Hoechst 33258 staining, mitochondrial activity using 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethylbenzimidazolyl-carbocyanine iodide (JC-1) staining, acrosome intactness by Coomassie blue staining, and capacitation status by chlortetracycline (CTC) staining. There were over 50% viable spermatozoa in boar semen extended with Zorlesco and Androhep extenders on Day 13 of storage. The percentage of JC-1-stained spermatozoa was 53.8 +/- 2.1% for Zorlesco and 57.7 +/- 1.60% for Androhep extenders on Day 13 of storage. The percentage of acrosome-intact spermatozoa detected by Coomassie blue staining was higher than that in the SYBR-14PI-, Hoechst 33258-, and JC-1-stained samples in our study. The results from SYBR-14/PI, Hoechst 33258, JC-1, and Coomassie blue staining were highly correlated (r > or = 0.9461). There were less than 15% capacitated spermatozoa in the semen extended with BTS, Androhep and Zorlesco extenders during 9 days of storage. However, most viable boar spermatozoa became capacitated by Day 13 of storage. The rank order of four extenders for maintaining sperm viability and mitochondrial activity was as follows: Androhep, Zorlesco, BTS, KIEV.

    Full Text Available Here, we observed the uptake of membrane-impermeant molecules by cercariae as they penetrate the skin and are transformed into schistosomula. We propose that membrane-impermeant molecules, Lucifer Yellow, Propidium iodide and Hoechst 33258 enter the parasite through both thenephridiopore and the surface membrane and then diffuse throughout the body of the parasite. We present a hypothesis that the internal cells of the body of the schistosomulum represent a new host-parasite interface, at which skin-derived growth factors may stimulate receptors on internal membranes during transformation of the cercariae into the schistosomulum.

  9. Expression of early transcription factors Oct-4, Sox-2 and Nanog by porcine umbilical cord (PUC matrix cells

    Directory of Open Access Journals (Sweden)

    Schultz Bruce

    2006-02-01

    Full Text Available Abstract Background Three transcription factors that are expressed at high levels in embryonic stem cells (ESCs are Nanog, Oct-4 and Sox-2. These transcription factors regulate the expression of other genes during development and are found at high levels in the pluripotent cells of the inner cell mass. The downregulation of these three transcription factors correlates with the loss of pluripotency and self-renewal, and the beginning of subsequent differentiation steps. The roles of Nanog, Oct-4 and Sox-2 have not been fully elucidated. They are important in embryonic development and maintenance of pluripotency in ESCs. We studied the expression of these transcription factors in porcine umbilical cord (PUC matrix cells. Methods Cells were isolated from Wharton's jelly of porcine umbilical cords (PUC and histochemically assayed for the presence of alkaline phosphatase and the presence of Nanog, Oct-4 and Sox-2 mRNA and protein. PCR amplicons were sequenced and compared with known sequences. The synthesis of Oct-4 and Nanog protein was analyzed using immunocytochemistry. FACS analysis was utilized to evaluate Hoechst 33342 dye-stained cells. Results PUC isolates were maintained in culture and formed colonies that express alkaline phosphatase. FACS analysis revealed a side population of Hoechst dye-excluding cells, the Hoechst exclusion was verapamil sensitive. Quantitative and non-quantitative RT-PCR reactions revealed expression of Nanog, Oct-4 and Sox-2 in day 15 embryonic discs, PUC cell isolates and porcine fibroblasts. Immunocytochemical analysis detected Nanog immunoreactivity in PUC cell nuclei, and faint labeling in fibroblasts. Oct-4 immunoreactivity was detected in the nuclei of some PUC cells, but not in fibroblasts. Conclusion Cells isolated from PUC express three transcription factors found in pluripotent stem cell markers both at the mRNA and protein level. The presence of these transcription factors, along with the other

    DNA-damage in cells has been studied by use of spectrophotometry and fluorometry. The method is based on the differential fluorescence quantum yield of the fluorochrome Hoechst 33258 when bound to single and double stranded DNA, respectively. DNA-damage by doses of X-rays below 2 Gy was clearly detectable. Blue light from phototherapy lamps induced DNA-damage in human TMG-1 glioblastoma, but no significant effect could be observed after irradiation with green lamps. In the presence of bilirubin the amount of DNA-damage was increased, notably at high bilirubin concentration and by blue light. 9 refs; 12 figs

    We present two rapid and simplified detection methods for Escherichia coli involving the use of a hand-held potentiostat and a disposable screen-printed carbon electrode. E. coli is one of the indicator organisms used to access for food safety. Commonly, microbiological culture techniques take more than one day to yield results and therefore, a simple, cost-effective, in situ detection system is required for testing food safety. This report describes two complementary techniques for high- and low-sensitivity detection of E. coli. High-sensitivity detection relies upon quantification of DNA amplification by using polymerase chain reaction (PCR), while the simplified, low-sensitivity detection can be obtained through measurement of oxygen consumption due to respiration; importantly, both techniques utilize the same type of electrode. The former entails mixing the PCR mixture with Hoechst, an electro-active DNA intercalator, and then, measuring the oxidation current. Binding of Hoechst molecules to the amplified DNA causes the peak current to decrease because of the slow diffusion of the Hoechst-amplified DNA complex to the electrode surface. The results showed that the oxidation peak current of Hoechst decreased depending on the number of E. coli cells added to the PCR mixture as the template for amplification, and the sensitivity of the method was as low as a single bacterium. Oxygen consumption was detected by direct measurement of the cell-containing culture medium. This method required only 10 μL to be applied on the screen-printed electrode, and the reduction in oxygen current was clearly observed within 30 min when a minimum of 1 × 10 5 cells were present. These results were obtained without purifying the culture, and the samples were applied onto the electrode without any surface modifications. The techniques describes in this report are versatile, because they require the same type of electrode, have simplistic nature, use a hand-held potentiostat, and have

    Cases of suspected herb-induced liver injury (HILI) caused by herbal Traditional Chinese Medicines (TCMs) and of drug-induced liver injury (DILI) are commonly published in the scientific literature worldwide. As opposed to the multiplicity of botanical chemicals in herbal TCM products, which are often mixtures of several herbs, conventional Western drugs contain only a single synthetic chemical. It is therefore of interest to study how HILI by TCM and DILI compare with each other, and to what extent results from each liver injury type can be transferred to the other. China is among the few countries with a large population using synthetic Western drugs as well as herbal TCM. Therefore, China is well suited to studies of liver injury comparing drugs with TCM herbs. Despite some concordance, recent analyses of liver injury cases with verified causality, using the Roussel Uclaf Causality Assessment Method, revealed major differences in HILI caused by TCMs as compared to DILI with respect to the following features: HILI cases are less frequently observed as compared to DILI, have a smaller proportion of females and less unintentional rechallenge events, and present a higher rate of hepatocellular injury features. Since many results were obtained among Chinese residents who had access to and had used Western drugs and TCM herbs, such ethnic homogeneity supports the contention that the observed differences of HILI and DILI in the assessed population are well founded.

    The production of Na 2 + ions by off-resonant laser excitation in the 5800-6200A region mainly results from two-photon absorption by the Na 2 molecule to highly excited gerade states followed by (a) direct ionization by absorbing a third photon or (b) coupling to the molecular Na 2 D 1 PIμ Rydberg state which is subsequently ionized by absorbing a third photon. This mechanism, i.e., a two-photon resonance three photon ionization process, explains a recent experimental observation of Roussel et al. It is suggested that the very same mechanism is also responsible for a similar observation reported by Polak-Dingels et al in their work using two crossed Na beams. In the latter two studies the laser-induced associative ionization processes were reported to be responsible for producing the Na 2 + ion. From the ratio of molecular to atomic concentration in the crossed beam experiment of Polak-Dingels et al we estimate that the cross section for producing Na 2 + through laser-induced associative ionization is at least four orders of magnitude smaller than ionization through the two-photon resonance three photon ionization process in Na 2 molecules

    Many of the anorectic drugs that are metabolized to amphetamine and/or methamphetamine pose significant concerns in the interpretation of amphetamine-positive drug testing results. One of these drugs--clobenzorex--has been shown to produce amphetamine. Thirty milligrams of clobenzorex hydrochloride, in the form of a single Asenlix capsule (Roussel, Mexico), were administered orally to five human volunteers with no history of amphetamine, methamphetamine or clobenzorex use. Following administration, urine samples (total void volume) were collected ad lib for seven days and pH, specific gravity and creatinine values were determined. To determine the excretion profile of amphetamine and parent drug, samples were extracted, derivatized, and analyzed by gas chromatography/mass spectrometry (GC/MS) using a standard amphetamine procedure with additional monitoring of ions at m/z 91, 118, 125 and 364 for the detection of clobenzorex. Peak concentrations of amphetamine were detected at 4 to 19 h postdose and ranged from approximately 715 to 2474 ng/mL amphetamine. Amphetamine could be detected (> 5 ng/mL) in the urine in one subject for up to 116 h postdose. GC/MS was also used to determine the enantiomeric composition of the metabolite, amphetamine. This analysis revealed the metabolically derived amphetamine was only the d-enantiomer. This differs from previous literature which indicates clobenzorex is the racemic N-orthochlorobenzyl derivative of amphetamine.

    Full Text Available Drug-induced hepatotoxicity most commonly manifests as an acute hepatitis syndrome and remains the leading cause of drug-induced death/mortality and the primary reason for withdrawal of drugs from the pharmaceutical market. We report a case of acute liver injury in a 12-year-old Hispanic boy, who received a series of five antibiotics (amoxicillin, ceftriaxone, vancomycin, ampicillin/sulbactam, and clindamycin for cervical lymphadenitis/retropharyngeal cellulitis. Histopathology of the liver biopsy specimen revealed acute cholestatic hepatitis. All known causes of acute liver injury were appropriately excluded and (only drug-induced liver injury was left as a cause of his cholestasis. Liver-specific causality assessment scales such as Council for the International Organization of Medical Sciences/Roussel Uclaf Causality Assessment Method scoring system (CIOMS/RUCAM, Maria and Victorino scale, and Digestive Disease Week-Japan were applied to seek the most likely offending drug. Although clindamycin is the most likely cause by clinical diagnosis, none of causality assessment scales aid in the diagnosis.

    The effects of the interaction between Suillus luteus (L.) Roussel and Trichoderma virens (J.H. Mill., Giddens & A.A. Foster) Arx on Pinus sylvestris var. mongolica Litv. were studied using plant physiology, mycorrhizal science, forest pathology, and biochemistry. Seedling growth and physiological parameters were determined, including the colonization rate of mycorrhizal fungi, biomass, root activity, photosynthetic pigment content, soluble protein content, antioxidant enzyme activities, rhizosphere soil enzyme activities, and protective enzyme activities. In addition, an optimal resistance system involving T. virens, mycorrhizal fungus (S. luteus), and P. sylvestris var. mongolica seedlings was constructed. Synergies between S. luteus and T. virens were observed, and most of the parameters of P. sylvestris var. mongolica seedlings inoculated with S. luteus 30 days + T. virens were higher than other treatments. After three months, when compared the control, the S. luteus 30 days + T. virens treatment gave increases in height (42.3 %); collar diameter (66.7 %); fresh weight (54 %); dry weight (50 %); soluble protein content (69.86 %); root activity (150 %); chlorophyll a (77.6 %); chlorophyll b (70.5 %); carotenoids (144 %); CAT activity (876.9 %); POD activity (268.3 %); SOD activity (66.18 %); β-1,3-glucanase activity (125.8 %); chitinase activity (40 %); rhizosphere soil catalase activity (97.8 %); and phosphatase activity (266.7 %). These results indicate that there may be a stimulating factor between S. luteus and T. virens when they are inoculated together (S. luteus 30 days + T. virens).

    Tobramycin, an aminoglycoside antibiotic, is used in the treatment of Pseudomonas aeruginosa infections in cystic fibrosis patients. Tobramycin bioactivity, however, is antagonized by sputum. Glycoproteins (mucins) and high-molecular-weight DNA make up 2 to 3% (P. L. Masson and J. F. Heremans, p. 412-475, In M. J. Dulfano, ed., Sputum: Fundamentals and Clinical Pathology, 1973) and 3 to 10% (W. S. Chernick and G. J. Barbero, Pediatrics 24:739-745, 1959, and R. Picot, I. Das, and L. Reid, Thorax 33:235-242, 1978) of the dry weight of sputum, respectively. tobramycin binds to both mucins and DNA obtained from sputum (R. Ramphal, M. Lhermitte, M. Filliat, and P. Roussel, J. Antimicrob. Chemother. 22:483-490, 1988). In vitro, recombinant human DNase (rhDNase) hydrolyzes high-molecular-weight DNA of > 50 kb within sputum to fragments of 2 to 4 kb. Studying dialyzable tobramycin, we examined drug binding to whole sputum and to "mock sputum," which consisted of porcine gastric mucin and calf thymus DNA. We also studied the effects of rhDNase treatments of sputum, mock sputum, and calf thymus DNA on tobramycin binding. We found that treatments of sputum, mock sputum, and calf thymus DNA with rhDNase did not significantly increase the tobramycin bioactivity within the dialysates; surprisingly, sputum binding of tobramycin was increased by rhDNase. We conclude that rhDNase does not increase the bioactivity of tobramycin in sputum.

    Roussel De Carvalho uses the notion of superdiversity to draw attention to some of the pedagogical implications of teaching science in multicultural schools in cosmopolitan cities such as London. De Carvalho makes the case that if superdiverse classrooms exist then Science Initial Teacher Education has a role to play in helping future science teachers to become more knowledgeable and reflective about how to teach school students with a range of worldviews and religious beliefs. The aim of this paper is to take that proposition a step further by considering what the aims and content of a session in teacher education might be. The focus is on helping future teachers develop strategies to teach school students to think critically about the nature of science and what it means to have a scientific worldview. The paper draws on data gathered during an interview study with 28 students at five secondary schools in England. The data was analysed to discover students' perceptions of science and their perceptions of the way that science responds to big questions about being human. The findings are used to inform a set of three strategies that teachers could use to help young people progress in their understanding of the nature of science. These strategies together with the conceptual framework that underpins them are used to develop a perspective on what kinds of pedagogical content knowledge teacher education might usefully provide.

    Methimazole is an antithyroid drug that is widely used for the treatment of hyperthyroidism. As an inhibitor of the enzyme thyroperoxidase, methimazole is generally well-tolerated. However, there have been increasing reports of methimazole-induced liver damage, although this effect of methimazole has been limited by the absence of objective diagnosis of the liver condition or the inappropriate use of the Naranjo scale. We present the case of an elderly man with hyperthyroidism, gastritis, and epilepsy who developed liver damage after administration of multiple drugs. Considering the low sensitivity of the Naranjo scale in detecting rare reactions associated with liver damage, we used the Roussel-Uclaf Causality Assessment Method scale, with a finding of cholestatic jaundice hepatitis induced by methimazole. The patient's liver enzyme levels improved after discontinuation of methimazole. Our case underlines the possible hepatoxicity associated with the use of methimazole. A review of the literature confirmed a selective hepatoxicity risk in individuals of Asian ethnicity, which has not been identified in Caucasian or Black populations. Physicians should be aware of the risk of hepatoxicity when prescribing oral methimazole to patients of Asian ethnicity.

    Full Text Available We describe a case of acute liver injury and migratory arthralgia in a patient receiving bicalutamide treatment for prostate cancer. A 67-year-old male with metastatic prostate cancer presented with a 6-day history of migratory arthralgia. He had been undergoing treatment with bicalutamide for 4 months; 3 weeks prior to symptom appearance the bicalutamide dose had been increased. He had no other symptoms. Liver tests and inflammatory markers were markedly elevated. Serology for hepatitis viruses A, B, and C, CMV, and EBV and autoimmune causes were all negative, and an ultrasound of the upper abdomen was normal. There was no history of blood transfusion, intravenous drug abuse, or alcohol abuse. Due to the suspicion of a drug-induced symptomatology, bicalutamide was discontinued and the patient started on 30 mg prednisolone daily. Three weeks later he was symptom free and after 6 weeks his liver tests were almost normal. The Roussel Uclaf Causality Assessment Method (RUCAM suggested a high probability of liver injury. Bicalutamide has very rarely been reported as a causative agent for liver injury and to our knowledge never for migratory polyarthralgia. The migratory polyarthralgia was attributed to bicalutamide due to the absence of other etiological factors and the disappearance of symptoms after discontinuation of the drug. To our knowledge, this is the first published case report of migratory arthralgia and concomitant liver injury attributed to bicalutamide.

    Full Text Available The marine subsurface environment is considered the potentially largest ecosystem on Earth, harboring one-tenth of all living biota (Whitman et al., 1998 and comprising diverse microbial components (Inagaki et al., 2003, 2006; Teske, 2006; Inagaki and Nakagawa, 2008. In deep marine sediments, the discrimination of life is significantly more difficult than in surface sediments and terrestrial soils because buried cells generally have extremely low metabolic activities (D’Hondt et al., 2002, 2004, and a highly consolidated sediment matrix produces auto-fluorescence fromdiatomaceous spicules and other mineral particles (Kallmeyer et al., 2008. The cell abundance in marine subsurface sediments has conventionally been evaluated by acridine orange direct count (AODC; Cragg et al., 1995; Parkes et al., 2000 down to 1613 meters below the seafloor (mbsf (Roussel et al., 2008. Since the cell-derived AOsignals often fade out in a short exposure time, recognizing and counting cells require special training. Hence, such efforts to enumerate AO-stained cells from the subseafloor on photographic images have been difficult, and a verification of counts by other methods has been impossible. In addition, providing mean statistical values from low biomass sedimentary habitats has been complicated byphysical and time limitations, yet these habitats are considered critical for understanding the Earth’s biosphere close to the limits of habitable zones (Hoehler, 2004; D’Hondt et al., 2007.

    To evaluate a large anti-tumor necrosis factor (TNF)-treated pediatric inflammatory bowel disease cohort for drug-induced liver injury (DILI) following presentation of an index case with suspected DILI with autoimmune features after infliximab exposure. To characterize the incidence, natural history, and risk factors for liver enzyme elevation with anti-TNF use. We reviewed the index case and performed a retrospective cohort study of 659 children receiving anti-TNF therapy between 2000 and 2015 at a tertiary pediatric inflammatory bowel disease center. Patients with alanine aminotransferase (ALT) ≥×2 the upper limit of normal were included. The incidence, evolution, and risk factors for liver injury were examined with univariate and multivariable proportional hazards regression. Causality was assessed using the Roussel-Uclaf Causality Assessment Method. The index case, a teenage girl with Crohn's disease, developed elevated liver enzymes and features of autoimmune hepatitis on liver biopsy 23 weeks after starting infliximab. The injury resolved entirely within 4 months of withdrawing infliximab without additional therapy. Overall, 7.7% of our cohort developed new ALT elevations while on anti-TNF. Most ALT elevations were mild and transient and attributable to alternate etiologies. No additional clear cases of autoimmune hepatitis were identified. Transient liver enzyme abnormalities are relatively common among anti-TNF-treated children. Anti-TNF-related DILI with autoimmune features is rare but must be recognized so that therapy can be stopped. Copyright © 2017 Elsevier Inc. All rights reserved.

    Soil metal pollution can trigger evolutionary adaptation in soil-borne organisms. An in vitro screening test showed cadmium adaptation in populations of Suillus luteus (L.: Fr.) Roussel, an ectomycorrhizal fungus of pine trees. Cadmium stress was subsequently investigated in Scots pine (Pinus sylvestris L.) seedlings inoculated with a Cd-tolerant S. luteus, isolated from a heavy metal contaminated site, and compared to plants inoculated with a Cd-sensitive isolate from a non-polluted area. A dose-response experiment with mycorrhizal pines showed better plant protection by a Cd-adapted fungus: more fungal biomass and a higher nutrient uptake at high Cd exposure. In addition, less Cd was transferred to aboveground plant parts. Because of the key role of the ectomycorrhizal symbiosis for tree fitness, the evolution of Cd tolerance in an ectomycorrhizal partner such as S. luteus can be of major importance for the establishment of pine forests on Cd-contaminated soils. - The evolutionary adaptation for higher Cd tolerance in Suillus luteus, an ectomycorrhizal fungus, is of major importance for the amelioration of Cd toxicity in pine trees exposed to high Cd concentrations.

    Drug induced acute toxic hepatitis can be idiosyncratic. Albendazole, a widely used broad spectrum antiparasitic drug is generally accepted as a safe drug. It may cause asymptomatic transient liver enzyme abnormalities but acute toxic hepatitis is very rare. Case Report : Herein, we present the case of 47 year old woman with recurrent acute toxic hepatitis after a single intake of albendazole in 2010 and 2014. The patient was presented with symptoms and findings of anorexia, vomiting and jaundice. For diagnosis, other acute hepatitis etiologies were excluded. Roussel Uclaf Causality Assessment Method (RUCAM) score was calculated and found to be 10, which meant highly probable drug hepatotoxicity. Within 2 months, all pathological findings came to normal. There are a few reported cases of albendazole induced toxic hepatitis, but at adults, there is no known recurrent acute toxic hepatitis due to albendazole at this certainty according to RUCAM score. Physicians should be aware of this rare and potentially fatal adverse effect of albendazole. © Acta Gastro-Enterologica Belgica.

    Full Text Available Background: Telomerase is highly activated in most human cancer cells, therefore, its inhibition has been proposed as a novel and promising strategy for cancer therapy. Many plant-derived anticancer agents act through inhibition of telomerase activity and induction of apoptosis. β-ionone, a carotenoid compound isolated from Roseaceae, has been reported to possess anticancer properties. The present study was undertaken to examine the mechanism of β-ionone-induced apoptosis in human leukemia cell line K562 with special emphasis on its role in telomerase inhibition. Method: In this study the anti-proliferation effect of β-ionone on K562 cells was evaluated by MTT assay. Apoptosis rate was detected by Hoechst staining and flow cytometry analysis. Telomerase activity was measured by (TRAP ELISA assay. Results: Exposure of K562 cells to β-ionone caused a dose-dependent decrease in proliferation. Flow cytometry analysis and Hoechst staining showed that percentage of apoptotic cells markedly increased with an increase in β-ionone concentration. Compared to control cells, treatment of K562 cells with β-ionone resulted in a significant decrease of telomerase activity. Moreover, a positive correlation was detected between telomerase inhibition and apoptosis induction in the treated K562 cells. Conclusion: Based on these results, β-ionone is an appropriate candidate for inhibiting telomerase activity in K562 cells. Therefore, it may be utilized as a novel drug against some leukemia cell lines.

    Full Text Available Background Beta-ionone is an aroma compound found in the Rosaceae family. Some evidence supported that beta-ionone has a great potential for cancer prevention. To date, the anti-proliferative and apoptotic effects of beta-ionone in human leukemia cell line K562 were not studied. Objectives Hence, we investigated whether beta-ionone could inhibit cell growth and induce apoptosis in the K562 cells. Materials and Methods In this experimental study, human leukemia cell line K562 was cultured and anti-proliferation effect of beta-ionone with different doses (25 - 400 µm at different times (24 - 96 hours on treated cells was evaluated by the MTT assay. To determine apoptosis rate, the Hoechst 33342 staining and flow cytometry was performed. Results The MTT assay showed that beta-ionone inhibited proliferation of K562 cells in a dose-dependent manner significantly (P = 0.0008. Moreover, the increased apoptotic rate was found after incubation of K562 cells with 200 µm beta-ionone. The Hoechst staining and flow cytometry analysis indicated that beta-ionone could increase apoptosis of K562 cells in a dose-dependent manner. Conclusions The results demonstrated that beta-ionone has anti-proliferative and apoptotic effects on K562 cells, and in the future may be used in the treatment of some leukemia sub-types.

    Objective: To explore the effect of intravenous infusion of bone marrow stromal stem cells(MSCs) on cognitive function of rats after whole brain irradiation. Methods: MSCs were isolated and cultured from adult rats. After Sprague-Dawly female rats were anaesthetized with chloral hydrate, their whole cerebrum was irradiated with a single dose of 20 Gy by 6 MV X-ray. Seven days after irradiation, 4 x 106 Hoechst33342-1abelled MSCs were intravenously injected into the tail vein of these rats. Four and 8 weeks after transplantation, the learning and memorizing ability was measured with the Y maze test. Immunohistochemical method was used to identify MSCs or ceils derived from MSCs in the brain. Results: The learning and memorizing ability of irradiation groups were significantly different from that of normal control group (P < 0.01). Significant improvement of cognitive impairment was observed in rats treated with MSCs at 4 and 8 weeks after transplantation as compared with the controll groups (P<0.05). This showed that the MSCs survived and were localized to the brain tissue. The number of Hoechst33342 immunohistofluorescence positive cells and double-immunostaining cells significantly decreased in 8 weeks group as compared with the 4 weeks group. Conclusion: Marrow stromal stem cells delivered to the irradiation brain tissue through intravenous route improve the cognitive impairment after whole brain irradiation. These cells may survive and differentiate in the brain tissue of irradiated rats. (authors)

    Investigating the molecular changes of cancer cell nucleus with drugs treatment is crucial for the design of new anticancer drugs, the development of novel diagnostic strategies, and the advancement of cancer therapy efficiency. In order to better understand the action effects of drugs, accurate location and in situ acquisition of the molecular information of the cell nuclei are necessary. In this work, we report a microspectroscopic technique called dark-field and fluorescence coimaging assisted surface-enhanced Raman scattering (SERS) spectroscopy, combined with nuclear targeting nanoprobes, to in situ study Soma Gastric Cancer (SGC-7901) cell nuclei treated with two model drugs, e.g., DNA binder (Hoechst33342) and anticancer drug (doxorubicin, Dox) via spectral analysis at the molecular level. Nuclear targeting nanoprobes with an assembly structure of thiol-modified polyethylene glycol polymers (PEG) and nuclear localizing signal peptides (NLS) around gold nanorods (AuNRs) were prepared to achieve the amplified SERS signals of biomolecules in the cell nuclei. With the assistance of dark field/fluorescence imaging with simultaneous location, in situ SERS spectra in one cell nucleus were measured and analyzed to disclose the effects of Hoechst33342 and Dox on main biomolecules in the cell nuclei. The experimental results show that this method possesses great potential to investigate the targets of new anticancer drugs and the real-time monitoring of the dynamic changes of cells caused by exogenous molecules.

  11. Modification of radiation damage in mouse lung by DNA-binding radioprotectors

    Full text: The limited diffusion of Hoechst 33342 through cell layers, which has been exploited in mapping the location of cells in multi-cellular spheroids, and in vivo, reflects a general characteristic of DNA-ligands. This property may confer special advantages on DNA-binding radioprotectors in the context of radiotherapy, where it is important to minimise delivery of the radioprotector to the tumour. For example, one might expect limited diffusion to capillaries and systemic uptake following topical application to epithelial cells, which can be dose-limiting tissues in radiotherapy. These potential applications will require delivery of sufficient concentrations of the DNA-binding radioprotectors to cells in vivo. In this context, the findings of Young and Hill, who could not detect any radioprotective effect in an in vivo setting, is of concern. We have re-examined this question by investigating radioprotection in the mouse lung model. A single intravenous injection of Hoechst 33342 (80mg/kg) given 30min prior to the lung irradiation, extends the radiation dose required for death in 50% of mice at 16 weeks post irradiation, from 19Gy to 23Gy (ie: a DMF of 1.2). This is similar to the extent of radioprotection reported by Travis et al for WR2721 (300 mg/kg) in this model. These results auger well for the potential of the more potent radioprotectors, and indeed preliminary experiments with methylproamine in the mouse lung model suggests a DMF of 1.35

    Recent studies at this Institute have focused on determining the role of alveolar macrophages (AMs) in the transport of particles within and form the lung. For those studies, AMs previously labeled using the nuclear stain Hoechst 33342 and polychromatic Fluoresbrite microspheres (1 {mu}m diameter, Polysciences, Inc., Warrington, PA) were instilled into lungs of recipient F344 rats. The fate of the donor particles and the doubly labeled AMs within recipient lungs was followed for 32 d. Within 2-4 d after instillation, the polychromatic microspheres were found in both donor and resident AMs, suggesting that particle transfer occurred between the donor and resident AMs. However, this may also have been an artifact resulting from phagocytosis of the microspheres form dead donor cells or from the fading or degradation of Hoechst 33342 within the donor cells leading to their misidentification as resident AMs. The results support the earlier findings that microspheres in donor AMs can be transferred to resident AMs within 2 d after instillation.

    The interpretation of cell transplantation experiments is often dependent on the presence of an exogenous label for the identification of implanted cells. The exogenous labels Hoechst 33342, 5-bromo-2′-deoxyuridine (BrdU), PKH26, and Qtracker were compared for their labeling efficiency, cellular effects, and reliability to identify a human neural stem cell (hNSC) line implanted intracerebrally into the rat brain. Hoechst 33342 (2 mg/ml) exhibited a delayed cytotoxicity that killed all cells within 7 days. This label was hence not progressed to in vivo studies. PKH26 (5 μM), Qtracker (15 nM), and BrdU (0.2 μM) labeled 100% of the cell population at day 1, although BrdU labeling declined by day 7. BrdU and Qtracker exerted effects on proliferation and differentiation. PKH26 reduced viability and proliferation at day 1, but this normalized by day 7. In an in vitro coculture assay, all labels transferred to unlabeled cells. After transplantation, the reliability of exogenous labels was assessed against the gold standard of a human-specific nuclear antigen (HNA) antibody. BrdU, PKH26, and Qtracker resulted in a very small proportion (Exogenous labels can therefore be reliable to identify transplanted cells without exerting major cellular effects, but validation is required. The interpretation of cell transplantation experiments should be presented in the context of the label's limitations. PMID:27938486

    Nanovesicles released by Dictyostelium discoideum cells grown in the presence of the DNA-specific dye Hoechst 33342 have been previously shown to mediate the transfer of the dye into the nuclei of Hoechst-resistant cells. The present investigation extends this work by conducting experiments in the presence of hypericin, a fluorescent therapeutic photosensitizer assayed for antitumoral photodynamic therapy. Nanovesicles released by Dictyostelium cells exhibit an averaged diameter between 50 and 150 nm, as measured by transmission cryoelectron microscopy. A proteomic analysis reveals a predominance of actin and actin-related proteins. The detection of a lysosomal membrane protein (LIMP II) indicates that these vesicles are likely generated in the late endosomal compartment. The use of the hypericin-containing nanovesicles as nanodevices for in vitro drug delivery was investigated by fluorescence microscopy. The observed signal was almost exclusively located in the perinuclear area of two human cell lines, skin fibroblasts (HS68) and cervix carcinoma (HeLa) cells. Studies by confocal microscopy with specific markers of cell organelles, provided evidence that hypericin was accumulated in the Golgi apparatus. All these data shed a new light on in vitro drug delivery by using cell-released vesicles as carriers.

    Dye efflux assay evaluated by flow cytometry is useful for stem cell studies. The side population (SP) cells, characterized by the capacity to efflux Hoechst 33342 dye, have been shown to be enriched for hematopoietic stem cells (HSCs) in bone marrow. In addition, SP cells are isolated from various tissues and cell lines, and are also potential candidates for cancer stem cells. However, ultra violet (UV) light, which is not common for every flow cytometer, is required to excite Hoechst 33342. Here we showed that a fluorescent indoline dye ZMB793 can be excited by 488-nm laser, equipped in almost all the modern flow cytometers, and ZMB793-excluding cells showed SP phenotype. HSCs were exclusively enriched in the ZMB793-excluding cells, while ZMB793 was localized in cytosol of bone marrow lineage cells. The efflux of ZMB793 dye was mediated by ATP binding cassette (ABC) transporter Abcg2. Moreover, staining properties were affected by the side-chain structure of the dyes. These data indicate that the fluorescent dye ZMB793 could be used for the SP cell analysis. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available Praziquantel (PZQ is effective against all the evolutive phases of Schistosoma mansoni. Infected Biomphalaria glabrata snails have their cercarial shedding interrupted when exposed to PZQ. Using primary in vitro transformed sporocysts, labeled with the probe Hoechst 33258 (indicator of membrane integrity, and lectin of Glycine max (specific for carbohydrate of N-acetylgalactosamine membrane, we evaluated the presence of lysosomes at this evolutive phase of S. mansoni, as well as the influence of PZQ on these acidic organelles and on the tegument of the sporocyst. Although the sporocyst remained alive, it was observed that there was a marked contraction of its musculature, and there occurred a change in the parasite's structure. Also, the acidic vesicles found in the sporocysts showed a larger delimited area after contact of the parasites with PZQ. Damages to the tegument was also observed, as show a well-marked labeling either with Hoechst 33258 or with lectin of Glycine max after contact of sporocysts with the drug. These results could partially explain the interruption/reduction mechanism of cercarial shedding in snails exposed to PZQ.

    The interaction between turbulence and hydrogen-flames was investigated in an explosion tube. The flow velocity around single flow obstacles was measured with a laser-Doppler system and compared to the flame velocity which was recorded using photodiodes. The highest turbulence intensity (up to 10 m/s) and correspondingly the highest flame acceleration was measured in the shear layer downstream of the obstacle with the highest blockage ratio. A closure model based on probability density functions (PDF) was developed for the time averaged chemical reaction rate for the purpose of simulating turbulent combustion processes. Comparisons of the results gained from simulations using the PDF combustion modell showed good agreement with the measurements performed. [German] Die Wechselwirkung zwischen Turbulenz und Wasserstoff-Flammen wurde in einem Explosionsrohr untersucht. Die Stroemungsgeschwindigkeit wurde mit einem Laser-Doppler System an Einzelhindernissen gemessen und mit der Flammengeschwindigkeit, die mittels Photodioden erfasst wurde, verglichen. In der Scherschicht hinter dem Hindernis mit der hoechsten Blockierrate wurde die hoechste Turbulenzintensitaet (bis 10 m/s) und damit die hoechste Flammenbeschleunigung gemessen. Fuer numerische Simulationen der turbulenten Verbrennung wurde ein Schliessungsansatz fuer die zeitgemittelte chemische Reaktionsrate entwickelt, der auf Wahrscheinlichkeitsdichtefunktionen (englisch: PDF) basiert. Vergleichsrechnungen mit dem PDF-Verbrennungsmodell zeigten gute Uebereinstimmung mit den durchgefuehrten Messungen.

  20. Modification of the radiation sensitivity of human tumour cells by a bis-benzimidazole derivative

    Energy Technology Data Exchange (ETDEWEB)

    Smith, P J; Anderson, C O [Medical Research Council, Cambridge (UK)

    1984-10-01

    A comparison was made of the ability of either X-radiation or a DNA-specific ligand (the vital bis-benzimidazole dye; Hoechst 33342) to induce: cell killing, inhibition of de novo DNA synthesis, DNA strand breakage and the delay of cell division in human colon adenocarcinoma cells in vitro. Unlike radiation-induced cell killing, ligand-induced cytotoxicity appeared to be positively correlated with the extent of inhibition of de novo DNA synthesis-a feature consistent with the persistent binding of ligand molecules to nuclear DNA. Ligand-induced DNA strand-breaks disappeared slowly although ligand-treated cells retained apparently normal capacities to repair discrete radiogenic DNA strand-breaks. Pre-treatment of cells with Hoechst 33342 resulted in a dose-modifying enhancement of radiation resistance not associated with altered dosimetry for strand-break induction. However, radioresistance was accompanied by the protracted retention of cells in the G/sub 2/ phase of the cell cycle. We suggest that the results provide direct evidence that the retention of cells in G/sub 2/ phase is a sparing phenomenon and is triggered by the responses of chromatin domains to the presence of DNA damage.

    The plant Plectranthus hadiensis is a rich source of many bioactive phytochemicals, especially terpenoids. The terpenoid fraction was isolated and phytochemical characterization was done using GC-MS. The aim of the present study was to find out the antiproliferative activity and the mechanism of cell death induction by the terpenoid fraction on human colon cancer cells (HCT-15). MTT assay was performed with different concentrations of the fraction (10, 20, and 50 µg/mL) to obtain IC50 value for 24 h to induce cell death. The induction of apoptosis were studied by Hoechst staining, acridine orange/ethidium bromide staining, Comet assay, DNA fragmentation, and caspase-3 activity assays. The mechanism of apoptosis induction was studied by expression analysis of antiapoptotic Bcl-2 and proapoptotic Bax using RT-PCR and also by Western blot analysis of proteins involved in the apoptotic pathway. The terpenoid fraction induced significant morphological changes and DNA fragmentation in the cells. Positive Hoechst staining and acridine orange/ethidium bromide staining indicated apoptosis induction by the fraction. DNA fragmentation, which is a characteristic feature of apoptosis, was also observed. Upregulation of caspase-3 activity and proapoptotic Bax, and the downregulation of antiapoptotic Bcl-2 and COX-2 confirmed that the apoptosis induction was via the mitochondria-dependent pathway.

    2011-07-01

    The interaction of native calf thymus DNA with tartrazine in 10 mM Tris-HCl aqueous solution at neutral pH 7.4 was investigated. Tartrazine is a nitrous derivative and may cause allergic reactions, with a potential of toxicological risk. Also, tartrazine induces oxidative stress and DNA damage. Its DNA binding properties were studied by UV-vis and circular dichroism spectra, competitive binding with Hoechst 33258, and viscosity measurements. Tartrazine molecules bind to DNA via groove mode as illustrated by hyperchromism in the UV absorption band of tartrazine, decrease in Hoechst-DNA solution fluorescence, unchanged viscosity of DNA, and conformational changes such as conversion from B-like to C-like in the circular dichroism spectra of DNA. The binding constants (K(b)) of DNA with tartrazine were calculated at different temperatures. Enthalpy and entropy changes were calculated to be +37 and +213 kJ mol(-1), respectively, according to the Van't Hoff equation, which indicated that the reaction is predominantly entropically driven. Also, tartrazine does not cleave plasmid DNA. Tartrazine interacts with calf thymus DNA via a groove interaction mode with an intrinsic binding constant of 3.75 × 10(4) M(-1).

    A number of theories on the development of human consciousness have tried to incorporate all views on the subject into one integral theory. However, Ken Wilber is the first philosopher who managed to combine the external with the internal fields of study. Using Wilber’s integral theory, a number of researchers developed their own theories in their field of speciality. Jim Marion used Wilber’s development theory to show the evolution of consciousness from a Christian perspective. Steve McIntosh, an integral philosopher, takes Wilber’s ideas further, and even criticises him on a few points. Another important researcher following Wilber is Andre Marquis, who developed an integral questionnaire to help pastors gauge clients’ problems. James Fowler, Clare Graves and Bill Plotkin also researched the evolution of human consciousness. This article examines each of these researchers, and concludes with a glance at several viewpoints on the soul and the mystical union with God.

    Kramer, Owen N; Strom, Mark A; Ladizinski, Barry; Lio, Peter A

    Fred Wise (1881-1950) and Marion Sulzberger (1895-1983) are often credited with introducing the term atopic dermatitis to dermatology in 1933. This definition was based on atopy, a term first created by Arthur Coca (1875-1959) and Robert Cooke (1880-1960) in 1923, when they recognized an association between allergic rhinitis and asthma. Despite its recent introduction into our medical lexicon, historical precursors of atopic dermatitis date back to at least as early as 69-140 ce. In this contribution, we highlight both the prominent individuals credited with shaping the disorder into our current interpretation and the suspected historical precursors of this disease and reported treatments.

    2017-04-01

    This paper draws on Melanie Klein's (unpublished) observational notes of her infant grandson, written primarily in 1938 and 1939. Apart from moving glimpses into a young family's life, the notes contain astute observations of an infant's behavior and emotions. Compared with Klein's published writings, the style is less theoretical and polemical. Later, in his latency years, Klein's grandson was in analysis with Marion Milner, who in 1952 published a paper drawing on the treatment. The present paper focuses on (1) how observations and treatment of the same child and his family by clinicians in close relationships with each other (Klein, Milner, and Winnicott) fertilized reciprocal influence but also brought into question the validity of Klein's observations, and (2) the relative merits and contributions of various modalities in understanding the infant's psyche, including experimental research, direct observation, parent-infant psychotherapy, and reconstructions from older patients-as occurs, for example, in psychoanalysis. © 2017 The Psychoanalytic Quarterly, Inc.

    2015-01-01

    Streamflow in the Esopus Creek watershed is altered by two major watershed management activities carried out by the New York City Department of Environmental Protection as part of its responsibility to maintain a water supply for New York City: (1) diversion of water from the Schoharie Creek watershed to the Esopus Creek through the Shandaken Tunnel, and (2) impoundment of the Esopus Creek by a dam that forms the Ashokan Reservoir and subsequent release through the Catskill Aqueduct. Stakeholders in the Catskill region are interested and concerned about the extent to which these watershed management activities have altered streamflow, especially low and high flows, in the Esopus Creek. To address these concerns, natural (in the absence of diversion and impoundment) daily discharge from October 1, 1931, to September 30, 2012, was estimated for the U.S. Geological Survey streamgages at Coldbrook (station number 01362500), downstream of the Shandaken Tunnel discharge, and at Mount Marion (01364500), downstream of the Ashokan Reservoir.

  17. Magical arts: the poetics of play.

    Jacobus, Mary

    2005-01-01

    The paper argues that links between play and magic in British Object Relations point to the persistence of aesthetic concerns within psychoanalysis. Magical thinking is present in British Object Relations psychoanalysis from its beginnings in Klein's play technique and early aesthetic writings, surfacing elsewhere in Susan Isaac's educational experiments and her theories of metaphor. Marion Milner's clinical account of the overlapping areas of illusion and symbol-formation in a boy's war-games link the primitive rituals of Frazer's "The Golden Bough" with her patient's creativity. In Winnicott's concept of the transitional object, the theory of play achieves its apotheosis as a diffusive theory of culture or "private madness," and as a paradigm for psychoanalysis itself. Tracing the non-positivistic, mystical, and poetical elements in British Object Relations underlines the extent to which aesthetics is not just entangled with psychoanalysis, but constitutive of it in its mid-twentieth century manifestations.

  18. From essentialism to another way of doing politics: resuming the transformative potential of the politics of difference

    Full Text Available This article aims at resuming and critically scrutinizing the debate on the politics of difference taken among liberal feminist political theorists. Firstly, I shall provide an overview of theoretical attempts to legitimate the politicization of collective-based subjects taking into account the problem of essentialism. Then I will argue that an exclusive focus on the relationship between essentialism and the conceptualization of collective-based subjects tends to overshadow the relationship between the politicization of differences and a new way of doing politics. I will defend the view that the politicization of differences is transforming rather than undermining the functioning of the polity and the possibility of real social justice. I shall evaluate the works of Anne Phillips and Iris Marion Young as offering new ways of reshaping the political sphere in order to enable proper institutional action against structural inequalities.

    Siim, Birte

    political theories are based upon a democratic paradox: they are based on assumptions about political equality that contrasts with the political practice where women and minorities are marginalised in relation to political representation, influence and political power. The feminist theories have different...... understandings of politics and power and different visions of how to include women and marginalized groups in democracy. One example is Carole Pateman's theory about the sexual contract that interprets the social contract as an expression of men’s patriarchal power over women rooted in the contradiction between...... the public and private arena. Another contribution is Anne Phillips theory of a "politics of presence" to include both women and marginalized social groups in political institutions by changing the principles of representation, and a third contribution is Iris Marion Young’s "the politics of difference...

  2. Medical pluralism: global perspectives on equity issues.

    Science.gov (United States)

    Marian, Florica

    2007-12-01

    Over the last decades, awareness has increased about the phenomenon of medical pluralism and the importance to integrate biomedicine and other forms of health care. The broad variety of healing cultures existing alongside biomedicine is called complementary or alternative medicine (CAM) in industrialized countries and traditional medicine (TM) in developing countries. Considerable debate has arisen about ethical problems related to the growing use of CAM in industrialized countries. This article focuses on equity issues and aims to consider them from a global perspective of medical pluralism. Several dimensions of equity are explored and their interrelatedness discussed: access to care, research (paradigm and founding) and recognition. This so-called 'equity circle' is then related to Iris Marion Young's justice theory and particularly to the concepts of cultural imperialism, powerlessness and marginalisation.

    The Hestia Project is a multi-disciplinary effort to help better understand the spatial and temporal distribution of fossil fuel carbon dioxide (CO2) emission at urban scale. Onroad transportation is an essential source of CO2 emissions. This study examines two urban domains: Marion County (Indianapolis) and Los Angeles County and explores the methods and results associated with the spatial and temporal distribution of local urban onroad CO2 emissions. We utilize a bottom-up approach and spatially distribute county emissions based on the Annual Average Daily Traffic (AADT) counts provided by local Department of Transportation. The total amount of CO2 emissions is calculated by the National Mobile Inventory Model (NMIM) for Marion County and the EMission FACtors (EMFAC) model for Los Angeles County. The NMIM model provides CO2 emissions based on vehicle miles traveled (VMT) data at the county-level from the national county database (NCD). The EMFAC model provides CO2 emissions for California State based on vehicle activities, including VMT, vehicle population and fuel types. A GIS road atlas is retrieved from the US Census Bureau. Further spatial analysis and integration are performed by GIS software to distribute onroad CO2 emission according to the traffic volume. The temporal allocation of onroad CO2 emission is based on the hourly traffic data obtained from the Metropolitan Planning Orgnizations (MPO) for Marion County and Department of Transportation for Los Angeles County. The annual CO2 emissions are distributed according to each hourly fraction of traffic counts. Due to the fact that ATR stations are unevenly distributed in space, we create Thiessen polygons such that each road segment is linked to the nearest neighboring ATR station. The hourly profile for each individual station is then combined to create a "climatology" of CO2 emissions in time on each road segment. We find that for Marion County in the year 2002, urban interstate and arterial roads have

    The Indian moved at an exceptional high rate (18-20cm/year) after the birth of La Réunion hotspot, ≈65Ma ago and the Deccan volcanic province before the collision with the Asian continent. Other older plumes Marion, Kerguelen located in the Indian ocean are also associated with very fast plate motion. We present a high-resolution 3D anisotropic model of the Indian plate region down to 300 km depth, obtained by inverting a new massive database of surface-wave observations. The Rayleigh and Love wave dispersion measurements along 14,000 paths are made in a broad frequency range (16-250s). Our estimates of the depth to the Lithosphere-Asthenosphere Boundary (LAB) derived from seismic velocity Vsv variations at depth reveal large variations (120-250 km) beneath the different cratonic blocks. A low velocity layer associated with the Mid-lithospheric discontinuity is present when the root of the lithosphere is deep. This extensive anisotropic tomographic investigation of the Indian continent displays an almost north-south keel, 600km long and 300km wide, down to 250km depth. The keel is characterized by fast velocities, smaller than average radial and azimuthal anisotropies. The distribution of azimuthal anisotropy defines the flow lines around the keel, and, at the LAB, coincides with the APM direction of the Indian plate. The fast axis azimuths at 250 km depth are also in accordance with the results from SK(K)S splitting. Such a keel could probably perturb plume-induced flow in the asthenosphere. To determine the influence of such a keel on the interaction of India with several mantle plumes (Marion, Crozet, Kerguelen, La Réunion), we used laboratory experiments. Some preliminary results will be presented on the comparison between the laboratory flowlines and the direction of seismic anisotropy.

    Full Text Available The modernity establishes the basis of subjectivity from the Cartesian dualist separation of the mind as the active consciousness and subject and the body as a passive material object. This essay takes as standpoint the political philosophy of Iris Marion Young in relation to her phenomenological writings. Thus, it accepts a metaphysical approach on the body as lived body and situation which constructs subjectivity for any human being. It argues that the author gives to the body the ontological status that Cartesian tradition attributes to the consciousness alone. The essay reflects on different aspects of the social consequences of this tradition, and the new horizons that several feminist studies give in many significant ways to the embodiment political theory.

    La modernidad instaura las bases de la subjetividad a partir de la separación cartesiana que distingue entre la mente, como conciencia activa del sujeto, y el cuerpo, como objeto material pasivo de esa conciencia activa.

De esta manera, la autora confiere al cuerpo el estatus ontológico que aquella tradición cartesiana confiere a la sola conciencia.

  7. Parallel processing streams for motor output and sensory prediction during action preparation.

    Sensory consequences of one's own actions are perceived as less intense than identical, externally generated stimuli. This is generally taken as evidence for sensory prediction of action consequences. Accordingly, recent theoretical models explain this attenuation by an anticipatory modulation of sensory processing prior to stimulus onset (Roussel et al. 2013) or even action execution (Brown et al. 2013). Experimentally, prestimulus changes that occur in anticipation of self-generated sensations are difficult to disentangle from more general effects of stimulus expectation, attention and task load (performing an action). Here, we show that an established manipulation of subjective agency over a stimulus leads to a predictive modulation in sensory cortex that is independent of these factors. We recorded magnetoencephalography while subjects performed a simple action with either hand and judged the loudness of a tone caused by the action. Effector selection was manipulated by subliminal motor priming. Compatible priming is known to enhance a subjective experience of agency over a consequent stimulus (Chambon and Haggard 2012). In line with this effect on subjective agency, we found stronger sensory attenuation when the action that caused the tone was compatibly primed. This perceptual effect was reflected in a transient phase-locked signal in auditory cortex before stimulus onset and motor execution. Interestingly, this sensory signal emerged at a time when the hemispheric lateralization of motor signals in M1 indicated ongoing effector selection. Our findings confirm theoretical predictions of a sensory modulation prior to self-generated sensations and support the idea that a sensory prediction is generated in parallel to motor output (Walsh and Haggard 2010), before an efference copy becomes available.

    Background: Traditional Chinese Medicine (TCM) with its focus on herbal use is popular and appreciated worldwide with increased tendency, although its therapeutic efficacy is poorly established for most herbal TCM products. Treatment was perceived as fairly safe but discussions emerged more recently as to whether herb induced liver injury (HILI) from herbal TCM is a major issue; Methods: To analyze clinical and case characteristics of HILI caused by herbal TCM, we undertook a selective literature search in the PubMed database with the search items Traditional Chinese Medicine, TCM, alone and combined with the terms herbal hepatotoxicity or herb induced liver injury; Results: HILI caused by herbal TCM is rare and similarly to drugs can be caused by an unpredictable idiosyncratic or a predictable intrinsic reaction. Clinical features of liver injury from herbal TCM products are variable, and specific diagnostic biomarkers such as microsomal epoxide hydrolase, pyrrole-protein adducts, metabolomics, and microRNAs are available for only a few TCM herbs. The diagnosis is ascertained if alternative causes are validly excluded and causality levels of probable or highly probable are achieved applying the liver specific RUCAM (Roussel Uclaf Causality Assessment Method) as the most commonly used diagnostic tool worldwide. Case evaluation may be confounded by inappropriate or lacking causality assessment, poor herbal product quality, insufficiently documented cases, and failing to exclude alternative causes such as infections by hepatotropic viruses including hepatitis E virus infections; Conclusion: Suspected cases of liver injury from herbal TCM represent major challenges that deserve special clinical and regulatory attention to improve the quality of case evaluations and ascertain patients’ safety and benefit.

    Full Text Available Herb induced liver injury (HILI and drug induced liver injury (DILI share the common characteristic of chemical compounds as their causative agents, which were either produced by the plant or synthetic processes. Both, natural and synthetic chemicals are foreign products to the body and need metabolic degradation to be eliminated. During this process, hepatotoxic metabolites may be generated causing liver injury in susceptible patients. There is uncertainty, whether risk factors such as high lipophilicity or high daily and cumulative doses play a pathogenetic role for HILI, as these are under discussion for DILI. It is also often unclear, whether a HILI case has an idiosyncratic or an intrinsic background. Treatment with herbs of Western medicine or traditional Chinese medicine (TCM rarely causes elevated liver tests (LT. However, HILI can develop to acute liver failure requiring liver transplantation in single cases. HILI is a diagnosis of exclusion, because clinical features of HILI are not specific as they are also found in many other liver diseases unrelated to herbal use. In strikingly increased liver tests signifying severe liver injury, herbal use has to be stopped. To establish HILI as the cause of liver damage, RUCAM (Roussel Uclaf Causality Assessment Method is a useful tool. Diagnostic problems may emerge when alternative causes were not carefully excluded and the correct therapy is withheld. Future strategies should focus on RUCAM based causality assessment in suspected HILI cases and more regulatory efforts to provide all herbal medicines and herbal dietary supplements used as medicine with strict regulatory surveillance, considering them as herbal drugs and ascertaining an appropriate risk benefit balance.

    Full Text Available RUCAM (Roussel Uclaf Causality Assessment Method or its previous synonym CIOMS (Council for International Organizations of Medical Sciences is a well established tool in common use to quantitatively assess causality in cases of suspected drug induced liver injury (DILI and herb induced liver injury (HILI. Historical background and the original work confirm the use of RUCAM as single term for future cases, dismissing now the term CIOMS for reasons of simplicity and clarity. RUCAM represents a structured, standardized, validated, and hepatotoxicity specific diagnostic approach that attributes scores to individual key items, providing final quantitative gradings of causality for each suspect drug/herb in a case report. Experts from Europe and the United States had previously established in consensus meetings the first criteria of RUCAM to meet the requirements of clinicians and practitioners in care for their patients with suspected DILI and HILI. RUCAM was completed by additional criteria and validated, assisting to establish the timely diagnosis with a high degree of certainty. In many countries and for more than two decades, physicians, regulatory agencies, case report authors, and pharmaceutical companies successfully applied RUCAM for suspected DILI and HILI. Their practical experience, emerging new data on DILI and HILI characteristics, and few ambiguous questions in domains such alcohol use and exclusions of non-drug causes led to the present update of RUCAM. The aim was to reduce interobserver and intraobserver variability, to provide accurately defined, objective core elements, and to simplify the handling of the items. We now present the update of the well accepted original RUCAM scale and recommend its use for clinical, regulatory, publication, and expert purposes to validly establish causality in cases of suspected DILI and HILI, facilitating a straightforward application and an internationally harmonized approach of causality

The test was performed in a total of 180 normal and adrenalectomized rats. The extracts tested were: a an aqueous extract of cortico-adrenal cortex prepared by the Swingle and Pfiffner technique; b the same extract added with ascorbic acid (Supracortin Labor; c desoxycorticosterone acetate (Percortol Ciba and Syncortyl Roussell. Male rats were used, ranging from 40-200g, fed since the 18 th days old with a special diet, in which they were maintained until the day before the injection. Adrenalectomy was performed under urethane anesthesia. The fourth day after operation, food was removed and they were fasted for 24 hours. In the morning of the fifth day, injections of the material to be assayed were given at hourly and two hours intervals, during four to eight hours. One or two hours after the last injection, the animals were sacrified, the livers removed and dropped into a hot 30% solution of potassium hydroxide, and worked by Good, Kramer and Somogyi method. The glycogen was calculated as milligrams per lOOg of body and liver weight. The results obtained are shown in the tables I, II, and III. When several dosages of the same sample of extract were made (5 animals each dose, the amount of glycogen deposited in the liver per lOOg of body and liver weight, was found to be a positive function of the dose injected. The graph 2, shows these results. The synthetic compounds were ineffective. Our results are in agreement with those of Reinecke and Kendall and of Olson et al.

    2012-09-01

    Idiosyncratic drug-induced liver injury (DILI) is an important cause of morbidity and mortality following drugs taken in therapeutic doses. Hepatotoxicity is a leading cause of attrition in drug development, or withdrawal or restricted use after marketing. No age is exempt although adults and the elderly are at increased risk. DILI spans the entire spectrum ranging from asymptomatic elevation in transaminases to severe disease such as acute hepatitis leading to acute liver failure. The liver specific Roussel Uclaf Causality Assessment Method is the most validated and extensively used for determining the likelihood that an implicated drug caused DILI. Asymptomatic elevation in liver tests must be differentiated from adaptation. Drugs producing DILI have a signature pattern although no single pattern is characteristic. Antimicrobial and central nervous system agents including antiepileptic drugs are the leading causes of DILI worldwide. In the absence of a diagnostic test or a biomarker, the diagnosis rests on the evidence of absence of competing causes such as acute viral hepatitis, autoimmune hepatitis and others. Recent studies show that antituberculosis drugs given for active or latent disease are still a major cause of drug-induced liver injury in India and the West respectively. Presence of jaundice signifies a severe disease and entails a worse outcome. The pathogenesis is unclear and is due to a mix of host, drug metabolite and environmental factors. Research has evolved from incriminating candidate genes to genome wide analysis studies. Immediate cessation of the drug is key to prevent or minimize progressive damage. Treatment is largely supportive. N-acetylcysteine is the antidote for paracetamol toxicity. Carnitine has been tried in valproate injury whereas steroids and ursodeoxycholic acid may be used in DILI associated with hypersensitivity or cholestatic features respectively.

    We report the outcome of 50 consecutive patients with CR1 acute leukemia (AML = 22; ALL = 28) treated with autologous BMT, after cyclophosphamide and TBI, followed with a sequential high dose rIL2 regimen. rIL-2 (RU 49637 from Roussel-Uclaf, Romainville, France) was started after hematological reconstitution an average of 72 +/- 22 days post transplant. The schedule consisted of a continuous infusion over 5 cycles (Cycle 1: 5 days starting on day 1; cycle 2-5: 2 days starting on day 15, 29, 43 and 57). Patients were treated at 4 different dosages (12 (N = 40), 16 (N = 3), 20 (N = 2), 24 (N = 5) x 10(6) IU/m2/day). Toxicities were mainly related to capillary leak syndrome and thrombocytopenia. Patients received an average of 122 +/- 49 10(6) IU/m2. Two patients with AML died from toxicity. rIL-2 infusion was associated with very a high level of immune stimu-lation of both T-cells (P < 0.05) and natural killer (NK) cells (P < 0.05) and associated cytolytic functions (P < 0.05). With a minimal and median follow-up of 21 and 46 months, 3 year leukemia free survival is 41 +/- 6% overall, 39 +/- 10% and 43 +/- 8% for AML and ALL respectively. Relapse probabilities at 3 years are 59 +/- 11% for AML and 57 +/- 8% for ALL. We conclude that this short infusion of rIL-2 over 2 months, resulting in an increased immune stimulation, is not associated with a better leukemic control for patients with acute leukemia transplanted early after reaching first complete remission.

Given the chronic and complex nature of these patients, multiple disciplines are involved in their care. Recognizing difficulties with communication among team members and striving for improved efficiencies in our pretransplant listing process and in our inpatient care, our team was prompted to change the existing approach to patient care related to heart transplantation. Methods: Daily multidisciplinary rounds were instituted and the format of the weekly Multidisciplinary Review Committee (MDRC meetings was modified with the list of attendees broadened to include a larger interdisciplinary team. Additionally, the approach to patient care was analyzed for process improvement. Results: The quality improvements are improved communication and throughput, quantified in an 85% decrease in time to complete transplant evaluation, a 37% decrease in median length of stay posttransplantation, and a 33% reduction in the 30 day readmission rate. In addition, pre- and posttransplant caregivers now participate in MDRC in person or via an electronic meeting platform to support the continuum of care. Quality metrics were chosen and tracked via a transparent electronic platform allowing all involved to assess progress toward agreed upon goals. These were achieved in an 18 month time period following the recruitment of new leadership and invested team members working together as a multidisciplinary team to improve the quality of cardiac transplant care.

    Thirteen new ent-kaurane diterpenoids, stigmaydenes A-M (1-13), together with two known compounds (14, 15), were isolated from the crude extract of corn silk ( Zea mays). The structures of the compounds were confirmed by comprehensive spectroscopic analyses. The absolute configuration of compound 1 was defined by single-crystal X-ray diffraction. The absolute configurations of the compounds were also confirmed by comparison of experimental and calculated specific rotations. The compounds were evaluated for their neuroprotective effects against H 2 O 2 -induced SH-SY5Y cell injury, and compound 8 was active at 100 μM, as determined by flow cytometry (annexin V-FITC/PI staining) and Hoechst 33258 staining. The results suggested that compound 8 could protect neuronal cells from H 2 O 2 -induced injury by inhibiting apoptosis in SH-SY5Y cells.

  1. Laboratory injection molder for the fabrication of polymeric porous poly-epsilon-caprolactone scaffolds for preliminary mesenchymal stem cells tissue engineering applications

    2016-12-16

    This study presents a simple and rapid fabrication technique involving injection molding and particle leaching (IM/PL) to fabricate the porous scaffold for tissue engineering applications. Sodium chloride (NaCl) and Sucrose are separately mixed with the poly-epsilon-caprolactone (PCL) granules using a screwed thermo regulated extruder, than the biocompatible scaffolds are fabricated through injection molding. The micro/nano structure of the samples and their different grade of porosity were characterized by scanning electron microscopy and mercury intrusion porosimetry. Bone marrow-derived mesenchymal stem cells are chose to cell culture and Hoechst 33342 staining was used to verify the biocompatibility of the polymeric porous surfaces. We concluded that, by using the same fast solvent free injection/leaching process, the use of Sucrose as porogen, instead of NaCl, allowed the obtainment of biocompatible scaffolds with a higher grade of porosity with suitable cell adhesion capacity for tissue engineering purpose.

  2. Cytotoxicity of an 125I-labelled DNA ligand

    2000-01-01

    The subcellular distribution and cytotoxicity of a DNA-binding ligand [ 125 I]-Hoechst 33258 following incubation of K562 cells with the drug was investigated. The ability of a radical scavenger, dimethyl sulphoxide, to protect cells from the 125 I-decay induced cell death was also studied. Three different concentrations and specific activities of the drug were used to provide different ligand : DNA binding ratios. The results demonstrated a trend toward improved delivery of the ligand to the nucleus and to chromatin at higher ligand concentrations, with concomitant increased sensitivity to 125 I-decay induced cytotoxicity and decreased protection by dimethyl sulphoxide. This correlation of radiobiological parameters with subcellular drug distribution is consistent with the classical dogma that attributes cytotoxicity to DNA double-stranded breakage in the vicinity of the site of decay, where the high LET nature of the damage confers minimal sensitivity to radical scavenging

    Two new series of new compounds containing a 6-amino-substituted group or 6-acrylamide-substituted group linked to a 4-anilinoquinazoline nucleus have been discovered as potential EGFR inhibitors. These compounds proved efficient effects on antiproliferative activity and EGFR-TK inhibitory activity. Especially, N(6)-((5-bromothiophen-2-yl)methyl)-N(4)-(3-chlorophenyl)quinazoline-4,6-diamine (5e), showed the most potent inhibitory activity (IC50=3.11μM for Hep G2, IC50=0.82μM for A549). The EGFR molecular docking model suggested that the new compound is nicely bound to the region of EGFR, and cell morphology by Hoechst stain experiment suggested that these compounds efficiently induced apoptosis of A549 cells.

    Crypt survival in the mouse intestine has been used to examine effects of bisbenzimide radioprotectors. Intravenous delivery has been used for the present study in which the effects of methyl proamine (MP), a second generation Hoechst 33342 analogue have been examined. Recent results using the lung model suggest that MP is both more potent as a protector and less toxic than H 33342. The rapid nature of the crypt microcolony survival assay in mouse intestine provides an efficient way to examining factors which could impinge on the extent of radioprotection, for example, the interval between protector administration and radiation exposure. The data clearly show that for MP at 100 mg/kg, there is substantially increased crypt survival equivalent to a dose modification of about 1.33. The crypt scoring methods used indicate that protection is throughout the small intestine and preliminary data indicate that colon is also protected to a similar or slightly greater extent

    Fabrics which could be used for protective clothing for electrical workers was discussed. In Canada there are no stringent clothing rules for the electrical industry, but in the United States, the Federal Occupational Safety and Health Administration (OSHA) have made protective clothing an issue within the industry. Dupont`s Nomex, Westex`s Indura, and Hoechst Celanese`s PBI fibres are among the materials which have been through a series of thermal protection tests and are based on proven materials which are now being applied to work wear. The testing standards cover the ignition of the basic materials, untreated cottons, wools, and the thermal protection of flame resistant materials. The final tests are based on high current arc tests conducted on the fabrics used in the industry. These tests are now being conducted at Ontario Hydro`s High Current Test Facility preliminary to a Canadian standard being formulated and proposed in the very near future. 2 figs.

    1988-01-01

    Radioimunoassay of glucagon, lh, fsh, aldosterone, cortisol, acth, sth and lth was performed using preparations from the firms SORIN, AMERSHAM and HOECHST. The basal glucagon secretion was estimated in 403 diabetic patients and 84 normal subjects. It was transitorily suppressed by glucose. The alpha-cellular reactivity in diabetic patients was stimulated by insulin-induced hypoglycemia and with arginine and vasopressin. The tested group of diabetic patients had absolute hyperglucagonemia, despite the hyperglycemia, which is an evidence of abnormal alpha-cellular function. The insulin-dependent nature of hyperglucagonemia in diabetes mellitus and the hyperreactivity of glucagon secretion after protein stimulation was demonstrated. The correlation of these results leads to essential diagnostic inferences

    AIM: To explore the role of hepatitis C virus (HCV) envelope protein 2 (E2) in the induction of apoptosis.METHODS: A carboxyterminal truncated E2 (E2-661) was transiently expressed in several cultured mammalian cell lines or stably expressed in Chinese hamster ovary (CHO)cell line. Cell proliferation was assessed by 3H thymidine uptake. Apoptosis was examined by Hoechst 33258staining, flow cytometry and DNA fragmentation analysis.RESULTS: Reduced proliferation was readily observed in the E2-661 expressing cells. These cells manifested the typical features of apoptosis, including cell shrinkage,chromatin condensation and hypodiploid genomic DNA content. Similar apoptotic cell death was observed in an E2-661 stably expressing cell line.CONCLUSION: HCV E2 can induce apoptosis in cultured mammalian cells.

    In 55 patients with various alcoholic liver diseases, serum type III procollagen aminopeptide (PIIIP) was measured on admission, on biopsy (2-4 weeks after admission) and on discharge from hospital (3 months after admission) using RIA-gnost PIIIP coated tube, an assay kit recently launched by Hoechst Japan Limited. Serum PIIIP on admission showed a good correlation with the degree of hepatic fibrosis and was significantly higher in any disease group than in healthy controls, suggesting its usefulness as an indicator of hepatic fibrosis. After abstinence, however, serum PIIIP level exhibited an increasing tendency in all the disease groups expect alcoholic hepatitis, and the number of laboratory tests showing a significant correlation with PIIIP decreased as compared with that on admission. The mechanism of serum PIIIP elevations seen after abstience is yet to be elucidated in detail, considering their possible association with factors other than collagen synthesis in the liver.

    Full Text Available In this study, the effect of pulsed-low intensity ultrasound on cell proliferation, collagen production and glycosaminoglycan deposition by 3T3 fibroblasts encapsulated in alginate was evaluated. Hoechst 33258 assay for cell number, hydroxyproline assay for collagen content and dimethylamine blue assay for glycosaminoglycan content were performed on samples from cell cultures treated with pulsed-low intensity ultrasound and a control group. Pulsed-low intensity ultrasound shows no effect on cell proliferation, while collagen and glycosaminoglycan contents were consistently higher in the samples treated with pulsed-low intensity ultrasound, showing a statistically significant difference (p < 0.05 on day 10. Alcian blue staining showed that glycosaminoglycans were deposited around the cells in both groups. These results suggest that pulsed-low intensity ultrasound shows no effect on cell proliferation but has potential for inducing collagen and glycosaminoglycan production in cells cultured in alginate gels.

    We report on an optical aptamer sensor for cocaine detection. The cocaine sensitive fluorescein isothiocyanate (FITC)-labeled aptamer underwent a conformational change from a partial single-stranded DNA with a short hairpin to a double-stranded T-junction in the presence of the target. The DNA minor groove binder Hoechst 33342 selectively bound to the double-stranded T-junction, bringing the dye within the Förster radius of FITC, and therefore initiating minor groove binder based energy transfer (MBET), and reporting on the presence of cocaine. The sensor showed a detection limit of 0.2 μM. The sensor was also implemented on a carboxy-functionalized polydimethylsiloxane (PDMS) surface by covalently immobilizing DNA aptamers. The ability of surface-bound cocaine detection is crucial for the development of microfluidic sensors. Copyright © 2012 Elsevier B.V. All rights reserved.

    The ATP-binding cassette (ABC) transporter 2 (ABCG2) is expressed by stem cells in many organs and in stem cells of solid tumors. These cells are isolated based on the side population (SP) phenotype, a Hoechst 3342 dye efflux property believed to be conferred by ABCG2. Because of the limitations of this approach we generated transgenic mice that express Nuclear GFP (GFPn) coupled to the Puromycin-resistance gene, under the control of ABCG2 promoter/enhancer sequences. We show that ABCG2 is expressed in neural progenitors of the developing forebrain and spinal cord and in embryonic and adult endothelial cells of the brain. Using the neurosphere assay, we isolated tripotent ABCG2-expressing neural stem cells from embryonic mouse brain. This transgenic line is a powerful tool for studying the expression of ABCG2 in many tissues and for performing functional studies in different experimental settings.

    Full Text Available Several methods i.e. cooling, freezing, and freeze-drying have been widely used to preserve spermatozoa with various degree of success. Freeze-drying appears to provide a method to preserve spermatozoa in a dry state without requiring liquid nitrogen for storing frozen spermatozoa. Freeze-drying procedures can have a detrimental effect on plasma membrane and acrosomal cap of the spermatozoa. In this experiment study, the viability and subcellular changes of freeze-dried ram spermatozoa were evaluated using staining method and scanning electron microscopy. The results revealed that all freeze-dried spermatozoa were dead following evaluation using eosin staining and Hoechst-propidium iodide staining methods. Morover, plasma membrane and acrosomal cap of freeze-dried ram spermatozoa was disrupted observed using scanning electron microscope.

    Methylglyoxal (MG) is involved in the pathogenesis of diabetic complications via the formation of advanced glycation end products (AGEs) and reactive oxygen species (ROS). To clarify whether the antidiabetic drug metformin prevents Schwann cell damage induced by MG, we cultured mouse Schwann cells in the presence of MG and metformin. Cell apoptosis was evaluated using Hoechst 33342 nuclear staining, caspase-3 activity, and c-Jun-N-terminal kinase (JNK) phosphorylation. Intracellular ROS formation was determined by flow cytometry, and AMP-activated kinase (AMPK) phosphorylation was also examined. MG treatment resulted in blunted cell proliferation, an increase in the number of apoptotic cells, and the activation of caspase-3 and JNK along with enhanced intracellular ROS formation. All of these changes were significantly inhibited by metformin. No significant activation of AMPK by MG or metformin was observed. Taken together, metformin likely prevents MG-induced apoptotic signals in mouse Schwann cells by inhibiting the formation of AGEs and ROS

    Chinese hamster fibroblasts were pulse labelled with 5-bromodeoxyuridine and exposed at time intervals (Tsub(i)) to near-ultraviolet (U.V.A.) light in the presence of a bisbenzimidazole derivative (Hoechst 33342). The sensitivity of the cells in terms of colony forming ability fluctuated depending on Tsub(i). Inhibition of DNA synthesis also depended on Tsub(i) and was maximal when Tsub(i)=O. Using the alkaline elution technique it was shown that the effect of a large dose of light was to inhibit both initiation and elongation of DNA chains. These effects were most pronounced for Tsub(i)=O. It is concluded that DNA damage in an active replicon can inhibit initiation of new replicons and that damage localized behind the replication fork can retard elongation of nascent DNA chains. This effect on chain elongation decreases with increased distance of the damage from the replication fork.

    We demonstrate how a conventional confocal spinning-disk (CSD) microscope can be converted into a doubly resolving image scanning microscopy (ISM) system without changing any part of its optical or mechanical elements. Making use of the intrinsic properties of a CSD microscope, we illuminate stroboscopically, generating an array of excitation foci that are moved across the sample by varying the phase between stroboscopic excitation and rotation of the spinning disk. ISM then generates an image with nearly doubled resolution. Using conventional fluorophores, we have imaged single nuclear pore complexes in the nuclear membrane and aggregates of GFP-conjugated Tau protein in three dimensions. Multicolor ISM was shown on cytoskeletal-associated structural proteins and on 3D four-color images including MitoTracker and Hoechst staining. The simple adaptation of conventional CSD equipment allows superresolution investigations of a broad variety of cell biological questions.

    Organic fluorescent probes are widely used to detect key biomolecules; however, they often lack the photostability required for extended intracellular imaging. Here we report a new hybrid nanomaterial (peroxynanosensor, PNS), consisting of an organic fluorescent probe bound to a nanodiamond, that overcomes this limitation to allow concurrent and extended cell-based imaging of the nanodiamond and ratiometric detection of hydrogen peroxide. Far-red fluorescence of the nanodiamond offers continuous monitoring without photobleaching, while the green fluorescence of the organic fluorescent probe attached to the nanodiamond surface detects hydrogen peroxide on demand. PNS detects basal production of hydrogen peroxide within M1 polarised macrophages and does not affect macrophage growth during prolonged co-incubation. This nanosensor can be used for extended bio-imaging not previously possible with an organic fluorescent probe, and is spectrally compatible with both Hoechst 33342 and MitoTracker Orange stains for hyperspectral imaging.

    Guggulsterone, a sterol found in plants is used as an ayurvedic medicine for many diseases such as obesity, internal tumors, ulcers etc. E and Z are two isoforms of guggulsterone, wherein guggulsterone-E (GUGE) has also been shown to have anticancer potential. Most of the anticancer drugs target nucleic acids. Therefore, we studied the mode of interaction between ctDNA and GUGE using UV-Vis, fluorescence and CD spectroscopy, isothermal calorimetry along with molecular docking studies. Hoechst 3325, ethidium bromide and rhodamine-B displacement experiments confirms that GUGE binds in the minor groove of DNA. ITC results further suggest these interactions to be feasible and spontaneous with hydrogen bond formation and van der waals interactions. Lastly, molecular docking also suggests GUGE to be a minor groove binder interacting through a single hydrogen bond formation between OH group of GUGE and nitrogen (N3) of adenosine (A6).

    Interaction of the food additive tartrazine with double-stranded DNA was studied by spectroscopic and calorimetric techniques. Absorbance studies revealed that tartrazine exhibited hypochromism in the presence of DNA without any bathochromic effects. Minor groove displacement assay of DAPI and Hoechst 33258 suggested that tartrazine binds in the minor groove of DNA. The complexation was predominantly entropy driven with a smaller but favorable enthalpic contribution to the standard molar Gibbs energy. The equilibrium constant was evaluated to be (3.68 ± .08) × 10(4) M(-1) at 298.15 K. The negative standard molar heat capacity value along with an enthalpy-entropy compensation phenomenon proposed the involvement of dominant hydrophobic forces in the binding process. Tartrazine enhanced the thermal stability of DNA by 7.53 K under saturation conditions.

    Purpose: To compare a dedicated simulation model for hypoxia PET against tumor microsections stained for different parameters of the tumor microenvironment. The model can readily be adapted to a variety of conditions, such as different human head and neck squamous cell carcinoma (HNSCC) xenograft tumors. Methods: Nine different HNSCC tumor models were transplanted subcutaneously into nude mice. Tumors were excised and immunoflourescently labeled with pimonidazole, Hoechst 33342, and CD31, providing information on hypoxia, perfusion, and vessel distribution, respectively. Hoechst and CD31 images were used to generate maps of perfused blood vessels on which tissue oxygenation and the accumulation of the hypoxia tracer FMISO were mathematically simulated. The model includes a Michaelis–Menten relation to describe the oxygen consumption inside tissue. The maximum oxygen consumption rate M{sub 0} was chosen as the parameter for a tumor-specific optimization as it strongly influences tracer distribution. M{sub 0} was optimized on each tumor slice to reach optimum correlations between FMISO concentration 4 h postinjection and pimonidazole staining intensity. Results: After optimization, high pixel-based correlations up to R{sup 2} = 0.85 were found for individual tissue sections. Experimental pimonidazole images and FMISO simulations showed good visual agreement, confirming the validity of the approach. Median correlations per tumor model varied significantly (p < 0.05), with R{sup 2} ranging from 0.20 to 0.54. The optimum maximum oxygen consumption rate M{sub 0} differed significantly (p < 0.05) between tumor models, ranging from 2.4 to 5.2 mm Hg/s. Conclusions: It is feasible to simulate FMISO distributions that match the pimonidazole retention patterns observed in vivo. Good agreement was obtained for multiple tumor models by optimizing the oxygen consumption rate, M{sub 0}, whose optimum value differed significantly between tumor models.

    Histone deacetylase inhibitors represent a promising class of potential anticancer agents for the treatment of human malignancies. In this study, the effects of trichostatin A (TSA) on apoptosis, metastasis-associated gene expression, and activation of the Notch pathway in human pancreatic cancer cell lines were investigated. After treatment with TSA, cell viability and apoptosis were evaluated using the MTT [3-(4,5-dimethylthia-zol-2-yl)-2,5-diphenyltetrazolium bromide] assay, Hoechst 33258 staining, and flow cytometry. Moreover, RT-PCR and western blot analyses were performed to measure the expression levels of apoptosis-associated genes (Bcl-2, Bax, and caspase-3), metastasis-associated genes (E-cadherin, vimentin, and matrix metalloproteinases), and Notch pathway activation (Notch intracellular domain, NICD). The levels of matrix metalloproteinase 2 and NICD were also semi-quantified by immunoassay. Following treatment with TSA for 24 h, PANC-1, SW1990, and MIATACA-2 cells exhibited cell death. The MTT assay revealed that TSA significantly decreased cell viability in a dose-dependent manner in PANC-1 cells. The Hoechst 33258 staining and flow cytometry results evidenced a significant increase in PANC-1 cell apoptosis following TSA treatment. The expression levels of Bax and caspase-3 were increased significantly, whereas Bcl-2 was down-regulated after TSA treatment. In the PANC-1 cells that survived after TSA treatment, the expression levels of vimentin, E-cadherin, and MMP genes were altered by the promotion of potential metastasis and increased expression of NICD. TSA can induce apoptosis of pancreatic cancer cells. In addition, the up-regulation of metastasis-related genes and the activation of the Notch pathway in the survived PANC-1 cells may be associated with a too-low level of TSA or resistance to TSA.

    Myelodysplastic syndromes (MDS) are a group of heterogeneous diseases characterized by poorly formed blood cells. We wanted to elucidate the underlying molecular mechanism to better determine pathogenesis, prognosis, diagnosis, and treatment for patients with MDS. We compared gene expression levels between normal and MDS tissue samples by immunohistochemical analysis. We studied the proliferation, survival, and migration of MDS cells using the EDU assay, colony formation, and transwell assays. We assessed the apoptotic rate and cell cycle status using flow cytometry and Hoechst staining. Finally, we evaluated RNA and protein expressions using polymerase chain reaction and Western blots, respectively. We found that resveratrol suppressed SKM-1 (an advanced MDS cell line) proliferation in a dose-dependent manner. Consistent with this finding, the EDU and colony formation assays also showed that resveratrol inhibited SKM-1 growth. Moreover, flow cytometry and Hoechst 33258 staining demonstrated that resveratrol induced apoptosis and a change in cell cycle status in SKM-1 cells, while the transwell assay showed that resveratrol reduced the migratory ability of SKM-1 cells. Resveratrol also decreased the expression of CCND1 (a gene that encodes the cyclin D1 protein) and increased expressions of KMT2A [lysine (K)-specific methyltransferase 2A] and caspase-3, suggesting that resveratrol exerts its effect by regulating CCND1 in SKM-1 cells. In addition, a combination of resveratrol and the PI3K/AKT inhibitor LY294002 exhibited a stronger inhibitory effect on the SKM-1 cells, compared with resveratrol alone. Our study proved that resveratrol suppresses SKM-1 growth and migration by inhibiting CCND1 expression. This finding provides novel insights into the pathogenesis of MDS and might help develop new diagnosis and treatment for patients with MDS.

    Curcumin, a natural polyphenolic compound and it is isolated from the rhizome of Curcuma longa, have been reported to possess anticancer effect against stage I and II colon cancer. However, the effect of curcumin on colon cancer at Dukes' type C metastatic stage III remains still unclear. In the present study, we have investigated the anticancer effects of curcumin on p53 mutated COLO 320DM human colon adenocarcinoma cells derived from Dukes' type C metastatic stage. The cellular viability and proliferation were assessed by trypan blue exclusion assay and MTT assay, respectively. The cytotoxicity effect was examined by lactate dehydrogenase (LDH) cytotoxicity assay. Apoptosis was analyzed by DNA fragmentation analysis, Hoechst and propidium iodide double fluorescent staining and confocal microscopy analysis. Cell cycle distribution was performed by flow cytometry analysis. Here we have observed that curcumin treatment significantly inhibited the cellular viability and proliferation potential of p53 mutated COLO 320DM cells in a dose- and time-dependent manner. In addition, curcumin treatment showed no cytotoxic effects to the COLO 320DM cells. DNA fragmentation analysis, Hoechst and propidium iodide double fluorescent staining and confocal microscopy analysis revealed that curcumin treatment induced apoptosis in COLO 320DM cells. Furthermore, curcumin caused cell cycle arrest at the G1 phase, decreased the cell population in the S phase and induced apoptosis in COLO 320DM colon adenocarcinoma cells. Together, these data suggest that curcumin exerts anticancer effects and induces apoptosis in p53 mutated COLO 320DM human colon adenocarcinoma cells derived from Dukes' type C metastatic stage.

    Compound MQA (1,5-O-dicaffeoyl-3-O-[4-malic acid methyl ester]-quinic acid) is a natural caffeoylquinic acid derivative isolated from Arctium lappa L. roots. This study aims to explore the neuroprotective effects of MQA against hydrogen peroxide (H 2 O 2 )-induced oxidative stress in SH-SY5Y neuroblastoma cells. The SH-SY5Y cells were divided into four groups, including control, 20 μM MQA, 200 μM H2O2, 200 μM H2O2 + 20 μM MQA groups. The effects of MQA on H 2 O 2 -induced cell death were measured by MTT and LDH assays. Hoechst 33342 and Annexin V-PI double staining were used to observed H2O2-induced apoptosis. Also, the effects of MQA on antioxidant system and mitochondrial pathway were explored. Further, steady-state phosphorylation levels of ERK1/2, Akt and GSK-3β were examined by Western blot analysis. Pretreatment with MQA prevented cell death in SH-SY5Y cells exposed to 200 μM H2O2 for 3 h. Meanwhile, Hoechst 33342 and Annexin V-PI double staining showed that MQA attenuated H 2 O 2 -induced apoptosis. These changes are related to elevation in SOD activity, reduction in MDA production and ROS formation, and increases in mitochondrial membrane potential (MMP). In addition, the potential mechanisms of MQA against H 2 O 2 -induced apoptosis are associated with increases in the Bcl-2/Bax ratio, decreases in cytochrome c release, caspase-3 and caspase-9 expressions, phosphorylation of ERK1/2, and dephosphorylation of AKT and GSK-3β. These findings suggest that protective effects of MQA against H 2 O 2 -induced apoptosis might be associated with mitochondrial apoptosis, ERK1/2 and AKT/GSK-3β pathway.

    Full text: Radioprotection using the minor groove binding DNA ligand Hoechst 33342 has been demonstrated in vitro, and more recently in vivo, in mouse lung. Intravenous administration was used for the lung studies, and both endothelial and alveolar epithelial cells-showed good up-take. Radiation damage to the endothelial cell population has also been postulated as important in late developing radionecrosis of spinal cord and brain. Endothelial cell density in brain can be readily determined by a fluorescent-histochemical technique. Treatment with a monoamine oxidase inhibitor and subsequent injection with L-DOPA results in an accumulation of dopamine (DA) in CNS endothelial cells. DA is converted to a fluorophore by exposure to paraformaldehyde, and cell numbers assayed by fluorescence microscopy. Earlier studies used this technique to monitor post-irradiation changes in endothelial cell density in rodent brain and showed the loss, within 24 hours, of a sensitive subpopulation comprising about 15% of the endothelial cells. Ten minutes after intravenous injection of Hoechst 33342 (80mg/kg) the ligand is confined by its limited penetration to the endothelial cells in mouse brain. When we irradiated at this time, there was protection against early endothelial cell loss. Ablation of the sensitive subpopulation in unprotected mice takes place over a dose range of 1 to 3 Gy γ-rays, but doses between 12 to 20 Gy are required in the presence of ligand. This protection equates to a very high dose modification factor of about 7 and possibly reflects a suppression of apoptosis in the sensitive endothelial subpopulation. The extent to which there is enhanced survival in the endothelial population as a whole and how the observed protection affects late CNS necrosis development has yet to be determined. However present results clearly show potential for the use of DNA-binding radioprotectors with limited penetration for investigations into the relative significance of

    Objective: To investigate the effect of Resveratrol combined with X-ray on radiosensitivity in glioma stem cells. Methods: The proliferation inhibition of glioma stem cells induced by X-rays and Resveratrol was assessed with MTT assay. The activation of proapoptotic effect was characterized by Hoechst 33258 stain. MDC stain and Western blot analysis were used to analyze the autophagy mechanism in X-rays-induced death of glioma stem cells. Results: MTT assay indicated that X-rays and Resveratrol decreased the viability of glioma stem cells (P<0.05); we found the proliferative inhibition of glioma stem cells was declined when we used 3-MA to inhibit autophagy(P<0.05). When the cells were treated by the Resveratrol and x-rays, their spherical shape were changed. Apoptosis was induced in glioma stem cells by combined X-rays and Resveratrol as detected by Hoechst 33258 staining. In addition, autophagy was induced in glioma stem cells in the combined treatment group as detected by MDC staining. Western blotting showed that Bcl-2 expression was decreased. in the combined treatment group (P<0.01), and the LC3-Ⅱ expression was increased in the combined treatment group (P<0.01). Conclusion: Resveratrol can increased the radiation sensitivity of glioma stem cells, the apoptosis and autophagy was induced in the glioma stem cells in the combined treatment X-rays and Resveratrol. Our results suggest that autophagy plays an essential role in the regulation of radiosensitization of glioma stem cells. (authors)

    Full Text Available Abstract Background Doxorubicin (DOX is an effective antineoplastic drug; however, clinical use of DOX is limited by its dose-dependent cardiotoxicity. It is well known that reactive oxygen species (ROS play a vital role in the pathological process of DOX-induced cardiotoxicity. For this study, we evaluated the protective effects of guggulsterone (GS, a steroid obtained from myrrh, to determine its preliminary mechanisms in defending against DOX-induced cytotoxicity in H9C2 cells. Methods In this study, we used a 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyl-2H-tetrazolium bromide (MTT assay, lactate dehydrogenase (LDH release measurements, and Hoechst 33258 staining to evaluate the protective effect of GS against DOX-induced cytotoxicity in H9C2 cells. In addition, we observed the immunofluorescence of intracellular ROS and measured lipid peroxidation, caspase-3 activity, and apoptosis-related proteins by using Western blotting. Results The MTT assay and LDH release showed that treatment using GS (1–30 μM did not cause cytotoxicity. Furthermore, GS inhibited DOX (1 μM-induced cytotoxicity in a concentration-dependent manner. Hoechst 33258 staining showed that GS significantly reduced DOX-induced apoptosis and cell death. Using GS at a dose of 10–30 μM significantly reduced intracellular ROS and the formation of MDA in the supernatant of DOX-treated H9C2 cells and suppressed caspase-3 activity to reference levels. In immunoblot analysis, pretreatment using GS significantly reversed DOX-induced decrease of PARP, caspase-3 and bcl-2, and increase of bax, cytochrome C release, cleaved-PARP and cleaved-caspase-3. In addition, the properties of DOX-induced cancer cell (DLD-1 cells death did not interfere when combined GS and DOX. Conclusion These data provide considerable evidence that GS could serve as a novel cardioprotective agent against DOX-induced cardiotoxicity.

    Disrupted iron metabolism and excess iron accumulation has been reported in the brains of Parkinson's disease (PD) patients. Because excessive iron can induce oxidative stress subsequently causing degradation of nigral dopaminergic neurons in PD, we determined the protective effect of a naturally occurring iron chelator, phytic acid (IP6), on 1-methyl-4-phenylpyridinium (MPP + )-induced cell death in immortalized rat mesencephalic/dopaminergic cells. Cell death was induced with MPP + in normal and iron-excess conditions and cytotoxicity was measured by thiazolyl blue tetrazolium bromide (MTT assay) and trypan blue staining. Apoptotic cell death was also measured with caspase-3 activity, DNA fragmentation, and Hoechst nuclear staining. Compared to MPP + treatment, IP6 (30 μmol/L) increased cell viability by 19% (P + treatment was decreased by 55% (P < 0.01) and 52% (P < 0.05), respectively with IP6. Cell survival was increased by 18% (P < 0.05) and 42% (P < 0.001) with 30 and 100 μmol/L of IP6, respectively in iron-excess conditions. A 40% and 52% (P < 0.001) protection was observed in caspase-3 activity with 30 and 100 μmol/L IP6, respectively in iron-excess condition. Similarly, a 45% reduction (P < 0.001) in DNA fragmentation was found with 100 μmol/L IP6. In addition, Hoechst nuclear staining results confirmed the protective effect of IP6 against apoptosis. Similar protection was also observed with the differentiated cells. Collectively, our results demonstrate a significant neuroprotective effect of phytate in a cell culture model of PD

    Toxicity of 3,4-methylenedioxymethamphetamine (MDMA) towards biogenic amine neurons is well documented and in primate brain predominantly affects serotonin (5-HT) neurons. MDMA induces damage of 5-HT axons and nerve fibres and intracytoplasmic inclusions. Whilst its pathobiology involves mitochondrially-mediated oxidative stress, we hypothesised MDMA possessed the capacity to activate autophagy, a proteostatic mechanism for degradation of cellular debris. We established a culture of ventral pons from embryonic murine brain enriched in 5-HT neurons to explore mechanisms of MDMA neurotoxicity and recruitment of autophagy, and evaluated possible neuroprotective actions of the clinically approved agent rilmenidine. MDMA (100 μM-1 mM) reduced cell viability, like rapamycin (RM) and hydrogen peroxide (H 2 O 2 ), in a concentration- and time-dependent manner. Immunocytochemistry revealed dieback of 5-HT arbour: MDMA-induced injury was slower than for RM and H 2 O 2 , neuritic blebbing occurred at 48 and 72 h and Hoechst labelling revealed nuclear fragmentation with 100 μM MDMA. MDMA effected concentration-dependent inhibition of [ 3 H]5-HT uptake with 500 μM MDMA totally blocking transport. Western immunoblotting for microtubule associated protein light chain 3 (LC3) revealed autophagosome formation after treatment with MDMA. Confocal analyses and immunocytochemistry for 5-HT, Hoechst and LC3 confirmed MDMA induced autophagy with abundant LC3-positive puncta within 5-HT neurons. Rilmenidine (1 μM) protected against MDMA-induced injury and image analysis showed full preservation of 5-HT arbours. MDMA had no effect on GABA neurons, indicating specificity of action at 5-HT neurons. MDMA-induced neurotoxicity involves autophagy induction in 5-HT neurons, and rilmenidine via beneficial actions against toxic intracellular events represents a potential treatment for its pathobiology in sustained usage.

    The extraction of fluorescence time course data is a major bottleneck in high-throughput live-cell microscopy. Here we present an extendible framework based on the open-source image analysis software ImageJ, which aims in particular at analyzing the expression of fluorescent reporters through cell divisions. The ability to track individual cell lineages is essential for the analysis of gene regulatory factors involved in the control of cell fate and identity decisions. In our approach, cell nuclei are identified using Hoechst, and a characteristic drop in Hoechst fluorescence helps to detect dividing cells. We first compare the efficiency and accuracy of different segmentation methods and then present a statistical scoring algorithm for cell tracking, which draws on the combination of various features, such as nuclear intensity, area or shape, and importantly, dynamic changes thereof. Principal component analysis is used to determine the most significant features, and a global parameter search is performed to determine the weighting of individual features. Our algorithm has been optimized to cope with large cell movements, and we were able to semi-automatically extract cell trajectories across three cell generations. Based on the MTrackJ plugin for ImageJ, we have developed tools to efficiently validate tracks and manually correct them by connecting broken trajectories and reassigning falsely connected cell positions. A gold standard consisting of two time-series with 15,000 validated positions will be released as a valuable resource for benchmarking. We demonstrate how our method can be applied to analyze fluorescence distributions generated from mouse stem cells transfected with reporter constructs containing transcriptional control elements of the Msx1 gene, a regulator of pluripotency, in mother and daughter cells. Furthermore, we show by tracking zebrafish PAC2 cells expressing FUCCI cell cycle markers, our framework can be easily adapted to different cell

    Full Text Available Introduction. Infection and apoptosis are combined triggers for inflammation in dental tissues. Octamer-binding transcription factor 4-B1 (OCT4B1, a novel spliced variant of OCT4 family, could respond to the cellular stress and possess antiapoptotic property. However, its specific role in dental pulpitis remains unknown. Methods. To investigate the effect of OCT4B1 on inflammation of dental pulp cells (DPCs, its expression in inflamed dental pulp tissues and DPCs was examined by in situ hybridization, real-time PCR, and FISH assay. OCT4B1 overexpressed DPCs model was established, confirmed by western blot and immunofluorescence staining, and then stimulated with Lipopolysaccharide (LPS. Apoptotic rate was determined by Hoechst/PI staining and FACS. Cell survival rate was calculated by CCK8 assay. Results. In situ hybridization, real-time PCR, and FISH assay revealed that OCT4B1 was extensively expressed in inflamed dental pulp tissues and DPCs with LPS stimulation. Western blot and immunofluorescence staining showed the expression of OCT4B1 and OCT4B increased after OCT4B1 transfection. Hoechst/PI staining and FACS demonstrated that less red/blue fluorescence was detected and apoptotic percentage decreased (3.45% after transfection. CCK8 demonstrated that the survival rate of pCDH-OCT4B1-flag cells increased. Conclusions. OCT4B1 plays an essential role in inflammation and apoptosis of DPCs. OCT4B might operate synergistically with OCT4B1 to reduce apoptosis.

    There is considerable interest in DNA sequence-selective DNA-binding drugs as potential inhibitors of gene expression. Five compounds with distinctly different base pair specificities were compared in their effects on the formation and elongation of the transcription complex from the lac UV5 promoter in a cell-free system. All were tested at drug levels which killed 90% of cells in a clonogenic survival assay. Cisplatin, a selective alkylator at purine residues, inhibited transcription, decreasing the full-length transcript, and causing blockage at a number of GG or AG sequences, making it probable that intrastrand crosslinks are the blocking lesions. A cyclopropylindoline known to be an A-specific alkylator also inhibited transcription, with blocks at adenines. The aniline mustard chlorambucil, that targets primarily G but also A sequences, was also effective in blocking the formation of full-length transcripts. It produced transcription blocks either at, or one base prior to, AA or GG sequences, suggesting that intrastrand crosslinks could again be involved. The non-alkylating DNA minor groove binder Hoechst 33342 (a bisbenzimidazole) blocked formation of the full-length transcript, but without creating specific blockage sites. A bisbenzimidazole-linked aniline mustard analogue was a more effective transcription inhibitor than either chlorambucil or Hoechst 33342, with different blockage sites occurring immediately as compared with 2 h after incubation. The blockages were either immediately prior to AA or GG residues, or four to five base pairs prior to such sites, a pattern not predicted from in vitro DNA-binding studies. Minor groove DNA-binding ligands are of particular interest as inhibitors of gene expression, since they have the potential ability to bind selectively to long sequences of DNA. The results suggest that the bisbenzimidazole-linked mustard does cause alkylation and transcription blockage at novel DNA sites. in addition to sites characteristic of

    AIM: To study the mechanism of Je-Chun-Jun (JCJ)-inducing the apoptosis of the human cervical carcinoma,HeLa cells. METHODS: The cell viability was assessed using MTT assay. The optical density was measured at 570 nm. The caspase activity was measured using 50 mmol/L of fluorogenic substrate, AC-DEVD-AMC (caspase3), AC-VEID-AMC (caspase-8) or AC-LEHD-AFC (caspase-9). To confirm the expression of proteins, Western blotting was performed. To detect the characteristic of apoptosis chromatin condensation, HeLa cells were stained with Hoechst 33258 in the presence of JCJ. For the cell cycle analysis, HeLa cells were incubated with Propidium iodide (PI) solution. Fluorescence intensity of cell cycle was measured using flow cytometry system. RESULTS:The loss of viability occurred following the exposure of 10 g/L JCJ. Cells treated with 10 g/L JCJ for 3 d exhibited the apoptotic morphology (brightly blue-fluorescent condensed nuclei by Hoechst 33258-staining) and the reduction of cell volume. Cells incubated with JCJ for 48 h were arrested at the G1 phase of cell cycle and their G1 checkpoint related gene products such as cyclin D1 were transiently decreased. We showed that JCJ induced the p38 MAPK activation in HeLa cells. The p38 MAPK inhibitor, SB203580 protected Hela cells from the JCJ-induced death as well as intervened the JCJ-induced accumulation of cells at the G1 phase. In contrast, MEK1 (-ERK upstream) inhibitor, PD98059 had no effect on HeLa cells. CONCLUSION: JCJ induced cell cycle arrest and apoptosis of HeLa cells through p38 MAPK pathway.
