    2013-02-01

    Full Text Available Claude Cahun is a writer and photographer born in Nantes in 1894. The purpose of this work is to explore her polymorphic and fluctuating identity through the artistic and affective link with her partner Suzanne Malherbe. Starting from the analysis of the iconic themes composing the visual symbol used by the two artists to sanction the exclusivity of their affair, we can conclude that Claude Cahun, by the means of her partner, becomes the absolute protagonist of her work, demolishing the wall between reality and art.

    2001-02-01

    Evans' syndrome is an unusual illness of autoimmune etiology, characterized by thrombocytopenia and hemolytic anemia. This is more frequent in females throughout first half of the life and during pregnancy. The present paper describes two pregnant women with Evans syndrome associated to preeclampsia. This report emphasizes how the hematology and coagulation abnormalities of preeclampsia could be added to those abnormalities observed in Evans' syndrome. This association constitutes a severe disease of difficult treatment.

    2010-01-01

    After more than 40 years at CERN, 15 of which were dedicated to ensuring that the LHC comes to completion, Lyn Evans is retiring. The Imperial College Professor and recently-elected Fellow of the British Royal Society has set himself new challenges, but plans to keep strong links with CERN. His big thank you goes to the many hundreds of people who built one of the most complex scientific instruments ever conceived by mankind. Note from the Editor: It is unusual for the Bulletin to adopt a question-and-answer style. However, we recognise that, with someone of Lyn’s stature, the appropriate thing to do is simply to give him the floor. Bulletin: Lyn, are you really leaving CERN? I am retiring but I will not completely lose contacts with CERN and the LHC. It’s time to slow down for me now but I will join the CMS Collaboration.

    The history, origin, identity, chemistry and use of Evans blue dye are described along with the first application to staining by Herbert McLean Evans in 1914. In the 1930s, the dye was marketed under the name, Evans blue dye, which was profoundly more acceptable than the ponderous chemical name.

  9. Methadone disrupts performance on the working memory version of the Morris water task.

    Science.gov (United States)

    Hepner, Ilana J; Homewood, Judi; Taylor, Alan J

    2002-05-01

    The aim of the study was to examine if administration of the mu-opiate agonist methadone hydrochloride resulted in deficits in performance on the Morris water tank task, a widely used test of spatial cognition. To this end, after initial training on the task, Long-Evans rats were administered saline or methadone at either 1.25, 2.5 or 5 mg/kg ip 15 min prior to testing. The performance of the highest-dose methadone group was inferior to that of the controls on the working memory version of the Morris task. There were also differences between the groups on the reference memory version of the task, but this result cannot be considered reliable. These data show that methadone has its most profound effect on cognition in rats when efficient performance on the task requires attention to and retention of new information, in this case, the relationship between platform location and the extramaze cues.

  10. Metrology at Philip Morris Europe

    2014-12-01

    Full Text Available The importance of the metrology function at Philip Morris Europe (PME, a multinational organisation producing at over 40 sites in the European, Middle Eastern and African Regions is presented. Standardisation of test methods and equipment as well as the traceability of calibration gauges to the same reference gauge are essential in order to obtain comparable results among the various production centers. The metrology function as well as the qualification of instruments and the drafting of test and calibration operating procedures for this region are conducted or co-ordinated by the Research and Development Department in Neuchatel, Switzerland. In this paper the metrology function within PME is presented based on the measurement of the resistance to draw for which the PME R&D laboratory is accredited (ISO/CEI 17025, as both a calibration and a testing laboratory. The following topics are addressed in this paper: traceability of calibration standards to national standards; comparison of results among manufacturing centres; the choice, the budget as well as the computation of uncertainties. Furthermore, some practical aspects related to the calibration and use of the glass multicapillary gauges are discussed.

    2003-04-01

    Philip Morris Companies, the world's largest and most profitable tobacco seller, has changed its corporate name to The Altria Group. The company has also embarked on a plan to improve its corporate image. Examination of internal company documents reveals that these changes have been planned for over a decade and that the company expects to reap specific and substantial rewards from them. Tobacco control advocates should be alert to the threat Philip Morris's plans pose to industry focused tobacco control campaigns. Company documents also suggest what the vulnerabilities of those plans are and how advocates might best exploit them.

  14. A strange case of Evans syndrome

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available Evans syndrome is a rare autoimmune disease presenting hemolytic anemia, thrombocytopenia and/or neutropenia. It may be associated with other autoimmune or lymphoproliferative diseases. It can have an extremely serious disease course and, in rare cases, this can even be life-threatening. First-line treatment consists of steroids and/or immunoglobulin. Further therapy with rituximab, vincristine, cyclophosphamide and other immunosuppressive drugs can be considered in unresponsive patients. We report a case of Evans syndrome in a 54-year old woman admitted to the Emergency Department (ED for asthenia. Etiopathogenic, clinical, therapeutic and evolutive aspects are discussed. In contrast to many cases described in the literature, our patient had a satisfactory response to corticoids. We also discuss how to make a specific diagnosis, even in a suburban ED with limited resources, in order to admit patients to the appropriate hospital department and allow the correct therapy to be started as early as possible.

  16. Obituary: David Stanley Evans, 1916-2004

    Science.gov (United States)

    Bash, Frank N.

    2005-12-01

    David Stanley Evans died on 14 November 2004 in Austin, Texas. He was a noted observational astronomer whose career was divided between South Africa and Texas. He also used the extensive historical collections at the University of Texas to write several books on the history of astronomy. He was born in Cardiff, Wales on 28 January 1916. David received his BA degree in mathematics in 1937 from Kings College, Cambridge. He became a PhD student at Cambridge Observatory in 1937, and was one of Sir Arthur Eddington's last surviving students. He received his PhD degree in 1941 with a dissertation entitled, "The Formation of the Balmer Series of Hydrogen in Stellar Atmospheres." He was a conscientious objector to war and, thus, spent the war years at Oxford working with physicist Kurt Mendelssohn on medical problems, involving cadavers, relating to the war. During these years, David was scientific editor of "Discovery", and he was editor of "The Observatory". David left England in 1946 in order to take up the position of Second Assistant at the Radcliffe Observatory, Pretoria, South Africa. He and H. Knox Shaw were the entire staff after R. O. Redman left, and they aluminized and installed the mirrors in the 74-inch telescope. His notable scientific contribution was to use lunar occultations to measure stellar angular diameters during the 1950s. He succeeded in determining the angular diameter of Antares and determined that Arcturus was not circular but had an elliptical shape. The elliptical shape was later shown to be an instrumental artifact, but the utility of using lunar occultations to measure stellar diameters and stellar multiplicity was conclusively demonstrated. T. Gold presented David's paper on lunar occultation angular diameters at the January 1953 meeting of the Royal Astronomical Society. For the rest of his life, David resented Gold's remarks, because he felt that he had been ridiculed. By 1953, David Evans was Chief Assistant at the Royal Observatory

  18. The Politics of Race and Patriarchy in Claire-Solange, âme africaine by Suzanne Lacascade

    Directory of Open Access Journals (Sweden)

    Valérie Orlando

    2005-01-01

    Full Text Available Racial discrimination, colonialism, marginalization, and imperial politics are the components of Martinican author Suzanne Lacascade's 1924 novel, Claire-Solange, âme africaine . This little-known work is shrouded in mystery. Less information is available about the author or under what circumstances she conceptualized and completed her novel. Lacascade probably contributed to various reviews and journals of the first days of the Négritude movement. The novel offers one of the first discourses on race, racial mixing, hierarchy, and colonialism as construed by blacks and whites. The author defies the power of men over women in French society of the early twentieth century. Racialized parameters are synthesized, most significantly, through the protagonist Claire-Solange's views and opinions on, two environments: the first is France, whose language she speaks fluently but in which she feels foreign; and the second African, a mythical place to which she is drawn due to her African ancestry filtered through her island home of Martinique. The author offers her readers a window on the life of a mulatta woman who is caught in the middle of white and black, forced, in the end, to live in a French, beige in-between, forever considered an étrangère because of her color.

  19. A Postcolonial Appraisal of Suzanne Collins’ The Hunger Games in the Light of Bhabha’s Ideas

    Directory of Open Access Journals (Sweden)

    Roya Ghaffarpour

    2013-05-01

    Full Text Available The present paper has tried to apply Bhabha's significant notions such as mimicry, ambivalence and stereotype to Suzanne Collins' The Hunger Games. Bhabha believes that in the interaction of the colonizer and the colonized both cultures are affected and neither culture can claim to have a pure and fixed status. In the process of interaction, the identity of both colonizer and the colonized undergoes serious changes. The colonizer stereotypes the colonized, regarding them as the inferior, thoughtless beings. The colonized seeing them in power internalize what they say, perceiving themselves as backward and the colonizer as superior, sophisticated beings. As they consider the colonizer as the sophisticated, powerful culture, they try to imitate them (this is actually what the colonizer wants which are not the exact copy but the parody of them, causing crack in the dominance of the colonizer. In this interaction, not only the colonized's identity but also the colonizer's alters. This is in fact what happens in Collins' The Hunger Games. The characters in the novel when encountering the colonizer's culture change their identity and become who they want them to be; however, the characters also through some resistance make the colonizer to follow what they assign for them. Moreover, during the course of the novel, the characters find an ambivalent character as a result of experiencing unhomeliness. This ambivalence makes them have a double consciousness, to be attracted toward the colonized culture and at the same time repulsed it.

    Full Text Available Este artículo ahonda en la perspectiva activista y transformadora de las artistas feministas que surgieron en la década de los años 70, indagando en su particular visión acerca de la capacidad del arte para crear nuevos modelos sociales integradores. A partir del caso de la artista norteamericana Suzanne Lacy, con quien las autoras han mantenido diversos encuentros de carácter público en el Centro de Arte Contemporáneo Matadero de Madrid, se pormenorizan las estrategias que el feminismo ha trabado en torno al arte público y se busca una redefinición de los ejes principales que sustentan el medio artístico actual: la autoría, la obra y su difusión y el valor final de la pieza. La investigación continúa con los estudios de caso de la artista ciberfeminista Shu Lea Cheang, la artista de origen paraguayo Faith Wilding y el colectivo madrileño Toxic Lesbian.

    2012-04-01

    Morris B. Parloff was considered an elder statesman in the field of psychotherapy research, and his wisdom and stewardship were of enormous benefit to several generations of psychotherapy researchers. Parloff received his bachelor's degree from Western Reserve University (1940), a degree in psychiatric social work from the University of Chicago (1942), and a doctorate in psychology from Western Reserve University (1953). Parloff spent most of his career (from 1953 until his retirement in 1983) as a researcher and administrator at the National Institute of Mental Health (NIMH). He was also on the senior faculty of the Washington School of Psychiatry, taught or consulted at a number of universities, and maintained a private practice of psychotherapy. In the NIMH intramural program, Parloff was chief of the Section on Personality in the Laboratory of Psychology. There he conducted a major longitudinal study on the personality characteristics of adolescent and adult scientists. In the NIMH extramural program, he served as chief of the Psychotherapy and Behavioral Intervention Section in the Clinical Research Branch (1972-1980), after which he became chief of the new Psychosocial Treatments Research Branch. Throughout his career, from his pioneering teaching and research on group psychotherapy through his 30 years at NIMH, Parloff provided researchers and practitioners with a broad understanding of the field of psychotherapy research, the complexity of its subject matter, and its relationship to the "real world." Often ahead of others in the field, Parloff dealt with many topics that retain their importance today, including the need to carefully define criteria for improvement in psychotherapy, the transmission of values in psychotherapy, the concepts of the placebo and of common factors in psychotherapy research, and the role of the patient-therapist relationship (in both individual and group therapy) and its impact on the outcome of therapy.

    Full Text Available Evans´ syndrome is the coexistence of autoimmune thrombocytopenia with autoimmune hemolytic anemia. It is rarely found during the course of a pregnancy. This makes treatment options more difficult, since some therapeutic drugs are teratogenic. The effects of Evans´ syndrome in the fetus and newborn are unknown given the low number of reported cases. We report the case of a patient with preconceptional diagnosis of Evans´ syndrome, who develops a hemolytic crisis during the course of a pregnancy, and diagnosis of intrauterine growth restriction (IUGR, treated at Clínica Ginecotocológica “A” at the Pereira Rossell Hospital Center, in Montevideo, Uruguay. Treatment options and evolution are analyzed, as well as previous reports.

  9. Thinking the "unthinkable": why Philip Morris considered quitting.

    Science.gov (United States)

    Smith, E A; Malone, R E

    2003-06-01

    To investigate the genesis and development of tobacco company Philip Morris's recent image enhancement strategies and analyse their significance. Internal Philip Morris documents, made available by the terms of the Master Settlement Agreement between the tobacco companies and the attorneys general of 46 states, and secondary newspaper sources. Searches of the Philip Morris documents website (www.pmdocs.com) beginning with terms such as "image management" and "identity" and expanding as relevant new terms (consultant names, project names, and dates), were identified, using a "snowball" sampling strategy. In the early 1990s, Philip Morris, faced with increasing pressures generated both externally, from the non-smokers' rights and public health communities, and internally, from the conflicts among its varied operating companies, seriously considered leaving the tobacco business. Discussions of this option, which occurred at the highest levels of management, focused on the changing social climate regarding tobacco and smoking that the tobacco control movement had effected. However, this option was rejected in favour of the image enhancement strategy that culminated with the recent "Altria" name change. This analysis suggests that advocacy efforts have the potential to significantly denormalise tobacco as a corporate enterprise.

  14. Morris-Thorne wormholes with a cosmological constant

    International Nuclear Information System (INIS)

    Lemos, Jose P.S.; Lobo, Francisco S.N.; Oliveira, Sergio Quinet de

    2003-01-01

    First, the ideas introduced in the wormhole research field since the work of Morris and Thorne are reviewed, namely, the issues of energy conditions, wormhole construction, stability, time machines and astrophysical signatures. Then, spherically symmetric and static traversable Morris-Thorne wormholes in the presence of a generic cosmological constant Λ are analyzed. A matching of an interior solution to the unique exterior vacuum solution is done using directly the Einstein equations. The structure as well as several physical properties and characteristics of traversable wormholes due to the effects of the cosmological term are studied. Interesting equations appear in the process of matching. For instance, one finds that for asymptotically flat and anti-de Sitter spacetimes the surface tangential pressure P of the thin shell, at the boundary of the interior and exterior solutions, is always strictly positive, whereas for de Sitter spacetime it can take either sign as one would expect, being negative (tension) for relatively high Λ and high wormhole radius, positive for relatively high mass and small wormhole radius, and zero in between. Finally, some specific solutions with Λ, based on the Morris-Thorne solutions, are provided

    Full Text Available The pineapple’s leaf plant contains approximately 2.5% to 3.5% of strong white silky fibres. These fibres are useful and can be extracted from the leaves. There are a few ways to extract the fibre such as hand scrapping and by extraction machine. The objective of this research is to study the quality of fibre extraction by using different age of pineapple leaf. Next, the study aims to compare the quality of Josapine and Morris pineapple leaf with tensile test. Fibre yield percentage are calculated to determine which type of pineapple leaf produce high production of dry fibre. The mechanical properties of the fibres are analysed by Tensile Test under American Standard Testing Methods (ASTM C1577-03 and Scanning Electron Microscope (SEM. The result of the fibre yield percentage show the Josapine type on 12 month ages are the highest value fibre yield percentage which is 7.89%. Based on fibre yield percentages, it showed the Josapine type produce better dry fibre production compare to Morris type. Based on mechanical test, it showed Josapine type on 12 months ages are the strongest fibre compare to Morris type since it can withstand on 67.6 N of load.

  16. Spectral Analysis and Dirichlet Forms on Barlow-Evans Fractals

    2012-01-01

    We show that if a Barlow-Evans Markov process on a vermiculated space is symmetric, then one can study the spectral properties of the corresponding Laplacian using projective limits. For some examples, such as the Laakso spaces and a Spierpinski P\\^ate \\`a Choux, one can develop a complete spectral theory, including the eigenfunction expansions that are analogous to Fourier series. Also, one can construct connected fractal spaces isospectral to the fractal strings of Lapidus and van Frankenhu...

    2015-08-01

    Full Text Available OBJECTIVE: To document the experience of one referral service with patients diagnosed with Evans syndrome, the treatment and response and to briefly review current treatment strategies and results.METHODS: Patients enrolled in this study fulfilled criteria for Evans syndrome. Data were retrieved from the clinical files and electronic databases of the Department of Hematology, Hospital Universitario "Dr. José Eleuterio González". Treatment modalities and response and the use of additional therapies were evaluated. The literature was reviewed in the context of the clinical course of the studied patients.RESULTS: Six patients were diagnosed with Evans syndrome in the study period. Patient 1 was treated with steroids, relapsed twice and was again treated with steroids. Patient 2 treated initially with steroids plus intravenous immunoglobulin was subsequently lost to follow-up. A good response was achieved in Patients 3 and 4, who were treated with steroids plus rituximab; patient 4 also received danazol as a second-line therapy. However both relapsed and subsequently underwent splenectomy at ten and nine months, respectively. One patient, number 5, treated with steroids, danazol and rituximab did not relapse within four years of follow-up and Patient 6, who received steroids plus danazol did not relapse within three years of follow-up.CONCLUSION: Evans syndrome is an uncommon hematologic condition rarely diagnosed and not widely studied. Clinicians must have it in mind when evaluating a patient with a positive direct antiglobulin test, anemia and thrombocytopenia, since prognosis depends on its early recognition and opportune therapy, but even this leads to variable results.

  18. Hiro and Evans currents in Vertical Disruption Event

    The notion of Tokamak Magneto-Hydrodynamics (TMHD), which explicitly reflects the anisotropy of a high temperature tokamak plasma is introduced. The set of TMHD equations is formulated for simulations of macroscopic plasma dynamics and disruptions in tokamaks. Free from the Courant restriction on the time step, this set of equations is appropriate for high performance plasmas and does not require any extension of the MHD plasma model. At the same time, TMHD requires the use of magnetic field aligned numerical grids. The TMHD model was used for creation of theory of the Wall Touching Kink and Vertical Modes (WTKM and WTVM), prediction of Hiro and Evans currents, design of an innovative diagnostics for Hiro current measurements, installed on EAST device. While Hiro currents have explained the toroidal asymmetry in the plasma current measurements in JET disruptions, the Evans currents explain the tile current measurements in tokamaks. The recently developed Vertical Disruption Code (VDE) have demonstrated 5 regimes of VDE and confirmed the generation of both Hiro and Evans currents. The results challenge the 24 years long misinterpretation of the tile currents in tokamaks as ``halo'' currents, which were a product of misuse of equilibrium reconstruction for VDE.

    1979-10-01

    The General Electric Company is providing technical support to Battelle Pacific Northwest Laboratories in the analysis of the design, operation, and maintenance experience in the handling of nuclear fuel at the Independent Spent Fuel Storage Facility. The purpose of this report is to provide a description of spent fuel handling activities and systems, and an analysis of the storage performance as developed over the seven year operational history of the Morris Operation. Design considerations and performance are analyzed for both the basin and key supporting systems. The bases for this analysis are the provisions for containing radioactive by-product materials, for shielding from the radiation they emit, and for preventing the formation of a critical array. These provisions have been met effectively over the history of storage at Morris. The release of radioactive materials is minimized by the protection of the cladding integrity, the containment of the basin water, the removal of radioactive and other contaminants from the water, and by filtering and then dispersing the basin air. Four auxiliary systems are provided to accomplish this, the basin leak detection system, the filter, the coolers, and the building ventilation system. This successful history notwithstanding, action to reduce personnel exposure, to improve fuel handling reliability and to lessen the potential for accidents continues to be taken

    Full Text Available Industrial revolution had an impact on art as well as other fields of society in the years 1760-1860. The machines came to the front in together with bringing out production line to supply growing demand, and so the importance the art had diminished. The machines having some features like standard production, scales based on rules and geometric form having unnatural appearance caused the artists such as William Morris and John Ruskin to believe that the machine harmed the art. The artists such as Morris and Ruskin took a leading role in development of design idea by resisting the form of machine production devoid of art in the light of this ideas. The problem of design keeps as a current issue nowadays. That’s why, we could create a solution by having different perspectives based on previous experience and problems encountered nowadays. The problem of design keeps on up-to-date issue with the technology developing very fast today. So, this study was made with the aim to help us present right approaches towards today’s problems. This research, review of the literature obtained from architecture, history of art and industrial design on books- magazines the subject of the dissertation thesis Higher Education Center was formed with descriptive narratives. Another aim of the research carried out in this context the handmade, machine design is to examine the emerging issues in the transition to production.

    Full Text Available Evans syndrome (ES is a rare autoimmune disorder whose exact pathophysiology is unknown. It is characterized by the simultaneous or subsequent development of autoimmune hemolytic anemia (AIHA and immune thrombocytopenia (ITP. Intravascular hemolysis, with hemoglobinemia, is known to produce acute kidney injury; however, the development of intratubular hemoglobin casts (hemoglobin cast nephropathy in the setting of acute hemolysis is uncommon. Likewise, the association of ES and acute renal failure is equally uncommon. We present a case of a 7-year-old girl with ES who developed acute kidney injury in the setting of intravascular hemolysis and had widespread intratubular hemoglobin casts.

    Evans blue (EB) dye has owned a long history as a biological dye and diagnostic agent since its first staining application by Herbert McLean Evans in 1914. Due to its high water solubility and slow excretion, as well as its tight binding to serum albumin, EB has been widely used in biomedicine, including its use in estimating blood volume and vascular permeability, detecting lymph nodes, and localizing the tumor lesions. Recently, a series of EB derivatives have been labeled with PET isotopes and can be used as theranostics with a broad potential due to their improved half-life in the blood and reduced release. Some of EB derivatives have even been used in translational applications in clinics. In addition, a novel necrosis-avid feature of EB has recently been reported in some preclinical animal studies. Given all these interesting and important advances in EB study, a comprehensive revisiting of EB has been made in its biomedical applications in the review.

    The efforts of members of the tobacco industry to portray themselves as responsible corporations via ostensible commitment to improved labour practices and public philanthropy have attracted growing criticism. This is particularly true of corporate social responsibility (CSR) schemes undertaken in emerging nations that are designed to rehabilitate the tobacco industry's image among public, government and market opinions in North America and western Europe. In the case of Thailand, sponsorship of arts events and community groups has been one avenue of promoting the industry in a regulatory environment that severely curtails promotion and advertising. The Association of Southeast Asian Nations (ASEAN) Art Award, sponsored by Philip Morris (PM) has provided one such outlet for 10 years. Analysis of PM funding announcements since the end of the ASEAN art programme in Thailand reveals that recent donations to tobacco-related community organisations reinforces the extent to which seemingly generous acts are driven by corporate self-interest rather than social responsibility.

    Electroconvulsive therapy (ECT) is one of the most efficient treatments for severe major depression, but some patients suffer from retrograde memory loss after treatment. Electroconvulsive seizures (ECS), an animal model of ECT, have repeatedly been shown to increase hippocampal neurogenesis, and multiple ECS treatments cause retrograde amnesia in hippocampus-dependent memory tasks. Since recent studies propose that addition of newborn hippocampal neurons might degrade existing memories, we investigated whether the memory impairment after multiple ECS treatments is a cumulative effect of repeated treatments, or if it is the result of a delayed effect after a single ECS. We used the hippocampus-dependent memory task Morris water maze (MWM) to evaluate spatial memory. Rats were exposed to an 8-day training paradigm before receiving either a single ECS or sham treatment and tested in the MWM 24 h, 72 h, or 7 days after this treatment, or multiple (four) ECS or sham treatments and tested 7 days after the first treatment. A single ECS treatment was not sufficient to cause retrograde amnesia whereas multiple ECS treatments strongly disrupted spatial memory in the MWM. The retrograde amnesia after multiple ECS is a cumulative effect of repeated treatments rather than a delayed effect after a single ECS.

  11. "What Is Our Story?" Philip Morris's Changing Corporate Narrative.

    We sought to learn how employees reacted to changes in the corporate narrative of Philip Morris Companies (PMC) in the late 1990s and early 2000s. We analyzed archival internal tobacco industry documents about PMC's creation of a new corporate story. In response to litigation and public opprobrium, PMC replaced its market success-oriented corporate narrative with a new one centered on responsibility. Although management sought to downplay inconsistencies between the old and new narratives, some employees reportedly had difficulty reconciling them, concerned that the responsibility focus might affect company profitability. However, others embraced the new narrative, suggesting radical ideas to prevent youth smoking. These ideas were not adopted. PMC's new narrative was unconvincing to many of its employees, who perceived it either as a threat to the company's continued profits or as incongruous with what they had previously been told. As it had done with the public, PMC misled its employees in explaining a narrative repositioning that would help the company continue business as usual. Moving toward a tobacco endgame will require ongoing discursive and symbolic efforts to disrupt this narrative.

    Evans index is an estimate of ventricular size used in the diagnosis of idiopathic normal-pressure hydrocephalus (iNPH). Values >0.3 are considered pathological and are required by guidelines for the diagnosis of iNPH. However, there are no previous epidemiological studies on Evans index, and normal values in adults are thus not precisely known. We examined a representative sample to obtain reference values and descriptive data on Evans index. A population-based sample (n = 1235) of men and women aged ≥70 years was examined. The sample comprised people living in private households and residential care, systematically selected from the Swedish population register. Neuropsychiatric examinations, including head computed tomography, were performed between 1986 and 2000. Evans index ranged from 0.11 to 0.46. The mean value in the total sample was 0.28 (SD, 0.04) and 20.6% (n = 255) had values >0.3. Among men aged ≥80 years, the mean value of Evans index was 0.3 (SD, 0.03). Individuals with dementia had a mean value of Evans index of 0.31 (SD, 0.05) and those with radiological signs of iNPH had a mean value of 0.36 (SD, 0.04). A substantial number of subjects had ventricular enlargement according to current criteria. Clinicians and researchers need to be aware of the range of values among older individuals. © 2017 EAN.

  14. Public versus internal conceptions of addiction: An analysis of internal Philip Morris documents.

    Directory of Open Access Journals (Sweden)

    2018-05-01

    Full Text Available Tobacco addiction is a complex, multicomponent phenomenon stemming from nicotine's pharmacology and the user's biology, psychology, sociology, and environment. After decades of public denial, the tobacco industry now agrees with public health authorities that nicotine is addictive. In 2000, Philip Morris became the first major tobacco company to admit nicotine's addictiveness. Evolving definitions of addiction have historically affected subsequent policymaking. This article examines how Philip Morris internally conceptualized addiction immediately before and after this announcement.We analyzed previously secret, internal Philip Morris documents made available as a result of litigation against the tobacco industry. We compared these documents to public company statements and found that Philip Morris's move from public denial to public affirmation of nicotine's addictiveness coincided with pressure on the industry from poor public approval ratings, the Master Settlement Agreement (MSA, the United States government's filing of the Racketeer Influenced and Corrupt Organizations (RICO suit, and the Institute of Medicine's (IoM's endorsement of potentially reduced risk products. Philip Morris continued to research the causes of addiction through the 2000s in order to create successful potentially reduced exposure products (PREPs. While Philip Morris's public statements reinforce the idea that nicotine's pharmacology principally drives smoking addiction, company scientists framed addiction as the result of interconnected biological, social, psychological, and environmental determinants, with nicotine as but one component. Due to the fragmentary nature of the industry document database, we may have missed relevant information that could have affected our analysis.Philip Morris's research suggests that tobacco industry activity influences addiction treatment outcomes. Beyond nicotine's pharmacology, the industry's continued aggressive advertising

The boycott protested the company's support of Senator Jesse Helms (R-North Carolina), a leading opponent of AIDS funding and civil rights for lesbian, gay, bisexual and transgender (LGBT) people. ACT-UP demanded that Philip Morris sever its ties with Helms and acknowledge its responsibility to the LGBT community and to people with AIDS. To assess the impact of the boycott on the LGBT community, the tobacco industry, and the tobacco control movement; and to determine what lessons tobacco control advocates can extract from this case. Internal tobacco industry documents and newspaper archives. Search of tobacco industry documents websites using "boycott", "ACT-UP", "gay", and other terms. Philip Morris used the boycott to its own advantage. It exploited differences within the community and settled the boycott by pledging large donations to combat AIDS. Through corporate philanthropy, Philip Morris gained entrée to the LGBT market without appearing gay friendly. Many LGBT organisations, thirsty for recognition and funding from mainstream corporations, welcomed Philip Morris's overtures without considering the health hazards of tobacco. Unless the goal of a boycott is to convince the tobacco industry to abandon tobacco altogether, such actions invite the industry to expand its marketing under the guise of philanthropy. Tobacco control advocates should be clear about goals and acceptable settlement terms before participating in a boycott of a tobacco company.

    2009-01-01

    Through analysis of tobacco company documents, we explored how and why Philip Morris sought to enhance its corporate image among American women. Philip Morris regarded women as an influential political group. To improve its image among women, while keeping tobacco off their organizational agendas, the company sponsored women's groups and programs. It also sought to appeal to women it defined as "active moms" by advertising its commitment to domestic violence victims. It was more successful in securing women's organizations as allies than active moms. Increasing tobacco's visibility as a global women's health issue may require addressing industry influence.

    Full Text Available Evans Syndrome is a rare autoimmune disease consisting of hemolytic anemia, thrombocytopenia and/or neutropenia. It may be associated with other autoimmune or lymphoproliferative diseases. Its course can be extremely serious and, rarely, even life-threatening; thus it represents a excellent treatment challenge for the pediatric hematologist. First line treatment consists of steroids and/or immunoglobulin; further therapy with rituximab, vincristine, cyclophosphamide and other immunosuppressive drugs can be considered in unresponsive patients. We describe a baby with refractory Evans Syndrome that was cured by prolonged administration of mycophenolate mofetil and remained disease-free for 4 years after the discontinuation of treatment.

    The role of NMDA receptors in learning, memory and hippocampal function has long been recognized. Post-mortem studies have indicated that the expression or subunit composition of the NMDA glutamate receptor subtype might be related to the impaired cognitive functions found in schizophrenia patients. NMDA receptor antagonists have been used to develop animal models of this disorder. There is accumulating evidence showing that not only the acute but also the chronic application of NMDA receptor antagonists may induce schizophrenia-like alterations in behavior and brain functions. However, limited evidence is available regarding the consequences of NMDA receptor blockage during periods of adolescence and early adulthood. This study tested the hypothesis that a 2-week treatment of male Long-Evans and Wistar rats with dizocilpine (MK-801; 0.5 mg/kg daily) starting at postnatal days (PD) 30 and 60 would cause a long-term cognitive deficit and changes in the levels of NMDA receptor subunits. The working memory version of the Morris water maze (MWM) and active place avoidance with reversal on a rotating arena (Carousel) requiring cognitive coordination and flexibility probed cognitive functions and an elevated-plus maze (EPM) was used to measure anxiety-like behavior. The western blot method was used to determine changes in NMDA receptor subunit levels in the hippocampus. Our results showed no significant changes in behaviors in Wistar rats. Slightly elevated anxiety-like behavior was observed in the EPM in Long-Evans rats with the onset of treatment on PD 30. Furthermore, Long-Evans rats treated from PD 60 displayed impaired working memory in the MWM. There were; however, no significant changes in the levels of NMDA receptor subunits because of MK-801 administration. These findings suggest that a 2-week treatment starting on PD 60 in Long-Evans rats leads to long-term changes in working memory, but this deficit is not paralleled by changes in NMDA receptor subunits. These

  1. "The Big WHY": Philip Morris's failed search for corporate social value.

    McDaniel, Patricia A; Malone, Ruth E

    2012-10-01

    We examined Philip Morris USA's exploration of corporate social responsibility practices and principles and its outcome. We analyzed archival internal tobacco industry documents, generated in 2000 to 2002, related to discussions of corporate social responsibility among a Corporate Responsibility Taskforce and senior management at Philip Morris. In exploring corporate social responsibility, Philip Morris executives sought to identify the company's social value-its positive contribution to society. Struggling to find an answer, they considered dramatically changing the way the company marketed its products, apologizing for past actions, and committing the company to providing benefits for future generations. These ideas were eventually abandoned. Despite an initial call to distinguish between social and economic value, Philip Morris ultimately equated social value with providing shareholder returns. When even tobacco executives struggle to define their company's social value, it signals an opening to advocate for endgame scenarios that would encourage supply-side changes appropriate to the scale of the tobacco disease epidemic and consistent with authentic social value.

    From 1997 to 2000, Philip Morris implemented Project Sunrise. This paper discusses the impact of this project on national and Philip Morris's cigarette unit sales, public opinion about smoking and secondhand tobacco smoke, and national prevalence trends for tobacco use. A qualitative archival content analysis of Project Sunrise from 1997 to 2000, and a descriptive statistical analysis of cigarette unit sales and operating profits, acceptability of smoking and secondhand tobacco smoke, and national prevalence trends for tobacco use from 1996 to 2006. Qualitative data sources related to Project Sunrise found on WebCat, Pubmed.com, LexisNexis Academic and Philip Morris's website, and archived tobacco industry documents were analysed using NVivo Version 9.0. A descriptive statistical analysis of cigarette unit sales, public opinion about smoking and secondhand tobacco smoke, and national prevalence trends for tobacco use was undertaken. Project Sunrise was a high-level strategic corporate plan to maintain profits that included four possible scenarios resulting in seven interwoven strategies. However, national prevalence rates for tobacco use declined, sales of national and Philip Morris cigarettes declined, operating profits remained at substantially lower levels after 2000 from 2001 to 2006, and a large majority of Americans agreed that there were significant health dangers associated with smoking and secondhand tobacco smoke. The impact of Project Sunrise, including countering the anti-tobacco movement, was less than successful in the USA. Copyright © 2012 The Royal Society for Public Health. Published by Elsevier Ltd.

    To describe the nature and timing of, and population exposure to, Philip Morris USA's three explicit corporate image television advertising campaigns and explore the motivations behind each campaign. Analysis of television ratings from the largest 75 media markets in the United States, which measure the reach and frequency of population exposure to advertising; copies of all televised commercials produced by Philip Morris; and tobacco industry documents, which provide insights into the specific goals of each campaign. Household exposure to the "Working to Make a Difference: the People of Philip Morris" averaged 5.37 ads/month for 27 months from 1999-2001; the "Tobacco Settlement" campaign averaged 10.05 ads/month for three months in 2000; and "PMUSA" averaged 3.11 ads/month for the last six months in 2003. The percentage of advertising exposure that was purchased in news programming in order to reach opinion leaders increased over the three campaigns from 20%, 39% and 60%, respectively. These public relations campaigns were designed to counter negative images, increase brand recognition, and improve the financial viability of the company. Only one early media campaign focused on issues other than tobacco, whereas subsequent campaigns have been specifically concerned with tobacco issues, and more targeted to opinion leaders. The size and timing of the advertising buys appeared to be strategically crafted to maximise advertising exposure for these population subgroups during critical threats to Philip Morris's public image.

  12. Automated method to compute Evans index for diagnosis of idiopathic normal pressure hydrocephalus on brain CT images

    2017-03-01

    The early diagnosis of idiopathic normal pressure hydrocephalus (iNPH) considered as a treatable dementia is important. The iNPH causes enlargement of lateral ventricles (LVs). The degree of the enlargement of the LVs on CT or MR images is evaluated by using a diagnostic imaging criterion, Evans index. Evans index is defined as the ratio of the maximal width of frontal horns (FH) of the LVs to the maximal width of the inner skull (IS). Evans index is the most commonly used parameter for the evaluation of ventricular enlargement. However, manual measurement of Evans index is a time-consuming process. In this study, we present an automated method to compute Evans index on brain CT images. The algorithm of the method consisted of five major steps: standardization of CT data to an atlas, extraction of FH and IS regions, the search for the outmost points of bilateral FH regions, determination of the maximal widths of both the FH and the IS, and calculation of Evans index. The standardization to the atlas was performed by using linear affine transformation and non-linear wrapping techniques. The FH regions were segmented by using a three dimensional region growing technique. This scheme was applied to CT scans from 44 subjects, including 13 iNPH patients. The average difference in Evans index between the proposed method and manual measurement was 0.01 (1.6%), and the correlation coefficient of these data for the Evans index was 0.98. Therefore, this computerized method may have the potential to accurately compute Evans index for the diagnosis of iNPH on CT images.

  16. ‘Wot larx!’: William Morris, Charles Dickens, and Fatherly Feelings

    Directory of Open Access Journals (Sweden)

    Wendy Parkins

    2011-09-01

    Full Text Available This essay explores the significance of William Morris’s reading of Dickens for Morris’s articulation of fatherly feelings. Recent scholarship on Victorian fatherhood has begun to overturn the stereotype of the dour, emotionally distant paterfamilias as providing only a partial understanding of forms of middle-class fatherhood and William Morris may serve as an example of a Victorian father whose parenting style eschewed detached authoritarianism, and instead combined nurture, play, and creativity. While Morris referred to Dickens’s works and characters in letters to a range of correspondents, his repeated usage of Joe Gargery’s catchphrase ‘Wot larx!’ (variously spelled occurs exclusively in letters to his wife and daughters, especially the latter. I will consider how the character of Joe Gargery, who combines nurturing tenderness with manly labour, was deployed by Morris to perform a playful and affectionate paternal persona. While Morris’s use of Joe’s catchphrase seems to express a spontaneous overflow of powerful feeling its status as a quotation also works to mark (and mask a disavowal of powerfully ambivalent feelings concerning his own emotional agency as husband and father.

  17. Aerobic fitness relates to learning on a virtual morris water task and hippocampal volume in adolescents

    Herting, Megan M.; Nagel, Bonnie J.

    2012-01-01

    In rodents, exercise increases hippocampal neurogenesis and allows for better learning and memory performance on water maze tasks. While exercise has also been shown to be beneficial for the brain and behavior in humans, no study has examined how exercise impacts spatial learning using a directly translational water maze task, or if these relationships exist during adolescence – a developmental period which the animal literature has shown to be especially vulnerable to exercise effects. In this study, we investigated the influence of aerobic fitness on hippocampal size and subsequent learning and memory, including visuospatial memory using a human analogue of the Morris Water Task, in 34 adolescents. Results showed that higher aerobic fitness predicted better learning on the virtual Morris Water Task and larger hippocampal volumes. No relationship between virtual Morris Water Task memory recall and aerobic fitness was detected. Aerobic fitness, however, did not relate to global brain volume, or verbal learning, which might suggest some specificity of the influence of aerobic fitness on the adolescent brain. This study provides a direct translational approach to the existing animal literature on exercise, as well as adds to the sparse research that exists on how aerobic exercise impacts the developing human brain and memory.

    Evans and Stanovich (2013, this issue) defend the dual-processing theories of higher cognition after first criticizing them on fundamental grounds. To make that possible, they resurrect the very distinctions between the two alleged "types" of processing that they formerly had rejected. At the end, however, the default-interventionist model they embrace, seems similar to the single-process unimodel they contest. © The Author(s) 2013.

    A simple separatory glass bottle was used to improve separation effectiveness and cost efficiency while simultaneously creating a simpler system for separating biological compounds. Additionally, it was important to develop a scalable separation method so this would be applicable to both analytical and preparative separations. Compared to conventional foam separation methods, this method easily forms stable dry foam which ensures high purity of yielded fractions. A negatively charged surfactant, sodium dodecyl sulfate (SDS), was used as the ligand to carry a positively charged Rhodamine-G, leaving a negatively charged Evans Blue in the bottle. The performance of the separatory bottle was tested for separating Rhodamine-G from Evans Blue with sample sizes ranged from 1 to 12mg in preparative separations and 1-20μg in analytical separations under optimum conditions. These conditions including N 2 gas pressure, spinning speed of contents with a magnetic stirrer, concentration of the ligand, volume of the solvent, and concentration of the sample, were all modified and optimized. Based on the calculations at their peak absorbances, Rhodamine-G and Evans Blue were efficiently separated in times ranging from 1h to 3h, depending on sample volume. Optimal conditions were found to be 60psi N 2 pressure and 2mM SDS for the affinity ligand. This novel separation method will allow for rapid separation of biological compounds while simultaneously being scalable and cost effective. Published by Elsevier B.V.

    Morris Cohen is mainly remembered as a philosopher of history and law, a friend of jurists (Oliver Wendell Holmes, Felix Frankfurter), and a teacher of more prominent philosophers (e.g., Ernest Nagel, Paul Weiss, Morton White). But his unique position as a student of the work of Russell and Peirce led him to make a distinctive contribution to the debate over realism in in the 1910s. Largely ignored and completely uncited, his early papers formulated what would later be called "objective relativism," influencing the later work of Columbia naturalism, hence American philosophy, from the 1940s to the 1960s.

ES can be classified as a primary (idiopathic or secondary (associated with an underlying disease syndrome. We report a case of ES in an elderly patient in the presence of multiple trigger factors such as recent influenza vaccine, marginal zone lymphoma, and neuroendocrine tumor G1. Whether this association is casual or causal remains a matter of speculation. It is however necessary to have a thorough work-up in a newly diagnosed ES and a more accurate search of miscellaneous factors especially in elderly patients.

  16. How Philip Morris unlocked the Japanese cigarette market: lessons for global tobacco control.

    Science.gov (United States)

    Lambert, A; Sargent, J D; Glantz, S A; Ling, P M

    2004-12-01

    The Framework Convention on Tobacco Control includes tobacco advertising restrictions that are strongly opposed by the tobacco industry. Marketing strategies used by transnational tobacco companies to open the Japanese market in the absence of such restrictions are described. Analysis of internal company documents. Between 1982 and 1987 transnational tobacco companies influenced the Japanese government through the US Trade Representative to open distribution networks and eliminate advertising restrictions. US cigarette exports to Japan increased 10-fold between 1985 and 1996. Television advertising was central to opening the market by projecting a popular image (despite a small actual market share) to attract existing smokers, combined with hero-centred advertisements to attract new smokers. Philip Morris's campaigns featured Hollywood movie personalities popular with young men, including James Coburn, Pierce Brosnan, Roger Moore, and Charlie Sheen. Event sponsorships allowed television access despite restrictions. When reinstatement of television restrictions was threatened in the late 1980s, Philip Morris more than doubled its television advertising budget and increased sponsorship of televised events. By adopting voluntary advertising standards, transnational companies delayed a television advertising ban for over a decade. Television image advertising was important to establish a market, and it has been enhanced using Hollywood personalities. Television advertising bans are essential measures to prevent industry penetration of new markets, and are less effective without concurrent limits on sponsorship and promotion. Comprehensive advertising restrictions, as included in the Framework Convention for Tobacco Control, are vital for countries where transnational tobacco companies have yet to penetrate the market.

  17. Memory-Enhancing Activity of Palmatine in Mice Using Elevated Plus Maze and Morris Water Maze

    Full Text Available The present study was designed to evaluate the effect of palmatine on memory of Swiss young male albino mice. Palmatine (0.1, 0.5, 1 mg/kg, i.p. and physostigmine (0.1 mg/kg, i.p. per se were administered for 10 successive days to separate groups of mice. Effect of drugs on learning and memory of mice was evaluated using elevated plus maze and Morris water maze. Brain acetylcholinesterase activity was also estimated. Effect of palmatine on scopolamine- and diazepam-induced amnesia was also investigated. Palmatine (0.5 and 1 mg/kg and physostigmine significantly improved learning and memory of mice, as indicated by decrease in transfer latency using elevated plus maze, and decrease in escape latency during training and increase in time spent in target quadrant during retrieval using Morris water maze. The drugs did not show any significant effect on locomotor activity of the mice. Memory-enhancing activity of palmatine (1 mg/kg was comparable to physostigmine. Palmatine (1 mg/kg significantly reversed scopolamine- and diazepam-induced amnesia in mice. Palmatine and physostigmine also significantly reduced brain acetylcholinesterase activity of mice. Thus, palmatine showed memory-enhancing activity in mice probably by inhibiting brain acetylcholinesterase activity, through involvement of GABA-benzodiazepine pathway, and due to its antioxidant activity.

    To describe how the transnational tobacco industry has collaborated with local Asian tobacco monopolies and companies to promote a scientific and regulatory agenda. Analysis of previously secret tobacco industry documents. Transnational tobacco companies began aggressively entering the Asia market in the 1980s, and the current tobacco industry in Asia is a mix of transnational and local monopolies or private companies. Tobacco industry documents demonstrate that, in 1996, Philip Morris led an organisation of scientific representatives from different tobacco companies called the Asian Regional Tobacco Industry Science Team (ARTIST), whose membership grew to include monopolies from Korea, China, Thailand, and Taiwan and a company from Indonesia. ARTIST was initially a vehicle for PM's strategies against anticipated calls for global smoke-free areas from a World Health Organization secondhand smoke study. ARTIST evolved through 2001 into a forum to present scientific and regulatory issues faced primarily by Philip Morris and other transnational tobacco companies. Philip Morris' goal for the organisation became to reach the external scientific and public health community and regulators in Asia. The Asian tobacco industry has changed from an environment of invasion by transnational tobacco companies to an environment of participation with Philip Morris' initiated activities. With this participation, tobacco control efforts in Asia face new challenges as Philip Morris promotes and integrates its scientific and regulatory agenda into the local Asian tobacco industry. As the local Asian tobacco monopolies and companies can have direct links with their governments, future implementation of effective tobacco control may be at odds with national priorities.

  19. Philip Morris's website and television commercials use new language to mislead the public into believing it has changed its stance on smoking and disease.

    2007-12-01

    This paper analyses Philip Morris's evolving website and the legal strategies employed in its creation and dissemination. Internal tobacco documents were searched and examined and their substance verified and triangulated using media accounts, legal and public health research papers, and visits to Philip Morris's website. Various drafts of website language, as well as informal discussion of the website's creation, were located in internal Philip Morris documents. I compared website statements pertaining to Philip Morris's stance on cigarette smoking and disease with statements made in tobacco trials. Philip Morris created and disseminated its website's message that it agreed that smoking causes disease and is addictive in an effort to sway public opinion, while maintaining in a litigation setting its former position that it cannot be proved that smoking causes disease or is addictive. Philip Morris has not changed its position on smoking and health or addiction in the one arena where it has the most to lose-in the courtroom, under oath.

  20. “Preposterous thicks and thins”: i libri ideali di William Morris fra intermedialità e teoria sociale

    2015-12-01

    Full Text Available Fra le molteplici espressioni dell’osmosi fra arte verbale e visiva perseguita da William Morris, la stampa e la tipografia rivestono un ruolo peculiare. Il libro ideale di Morris – oggetto materiale e object d’art – solleva questioni cardinali che riguardano l’interdipendenza fra parola e immagine, i nessi fra forma e contenuto, il ruolo dell’arte nella società, le interazioni fra estetica e politica. Le ragioni che indussero Morris a criticare Giambattista Bodoni sono state tralasciate fino ad ora e richiedono una disamina, perché rivelano l’intersecarsi di orientamenti estetici ed ideologici nell’evoluzione della tipografia e dell’editoria fra la fine dell’Ottocento e gli inizi del Novecento.

  1. Joint reproductive autonomy: does Evans v Amicus Healthcare Ltd provide for a gender-neutral approach to assisted reproductive rights?

    Science.gov (United States)

    Allin, Michael J

    2015-06-01

    Assisted reproductive technology encompasses methods of achieving pregnancy by artificial or partially artificial means. Whilst these methods are more commonly used by couples suffering from problems of infertility, some forms of assistance are employed by fertile couples, for example pre-implantation genetic diagnosis. The overall regulatory framework in the UK is predominantly found in the Human Fertilisation and Embryology Act 1990. The usual rules relating to consent and autonomy apply and were discussed in depth in Evans v Amicus Healthcare Ltd and later in Evans v United Kingdom. This paper considers whether the Evans litigation envisages the possibility of further encouraging joint autonomy in the use of zygotes and whether there is a continuing right to autonomy by the party not bearing the pregnancy. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  2. In vitro autoradiography of ionotropic glutamate receptors in hippocampus and striatum of aged Long-Evans rats: relationship to spatial learning

    International Nuclear Information System (INIS)

    Gallagher, M.; Bizon, J.L.; Nicolle, M.M.

    1996-01-01

    Using in vitro autoradiography, we investigated [ 3 H]α-amino-3-hydroxy-5-methyl-4-isoxazolepropionate, [ 3 H]kainate and [ 3 H]N-methyl-d-aspartate binding in two forebrain regions, the hippocampus and striatum, of young (four months of age) and aged (24-25 months of age) Long-Evans rats that had previously been tested for spatial learning ability in the Morris water maze. Although there was substantial preservation of binding in the aged rats, reductions in binding were present in the aged rats that were specific to ligand and anatomical region. In the hippocampus of aged rats, [ 3 H]α-amino-3-hydroxy-5-methyl-4-isoxazolepropionate binding in CA1 and [ 3 H]kainate binding in CA3 were reduced. In contrast, N-methyl-d-aspartate binding was not significantly different between age groups. There was evidence of sprouting in the dentate gyrus molecular layer of aged rats, indicated by changes in the topography of [ 3 H]kainate binding. Binding density was analysed with respect to patch/matrix compartmentalization in the striatum. The most striking result was a large decrease in N-methyl-d-aspartate binding in aged rats that was not limited to any dorsal/ventral or patch/matrix area of the striatum. Additionally, [ 3 H]kainate binding in striatal matrix was modestly reduced in aged rats. Of these age effects, only N-methyl-d-aspartate binding in the striatum and [ 3 H]kainate binding in the CA3 region of the hippocampus were correlated with spatial learning, with lower binding in the aged rats associated with better spatial learning ability.Age-related alterations in ionotropic glutamate receptors differ with respect to the receptor subtype and anatomical region examined. The age effects were not neccessarily indicative of cognitive decline, as only two age-related binding changes were correlated with spatial learning. Interestingly, in these instances, lower binding in the aged rats was associated with preserved spatial learning, suggesting a compensatory reduction

    The quantitative evaluation of bradykinin and histamine with Evans blue labelled with iodine -125 or 131 is described. The activity upon vascular permeability was performed in the abdominal wall of rats injecting intravenously solution of labelled Evans blue and 0,1 ml of vasoactive drugs solution intradermally. Skin discs were cut with circular punch for external counting, quantitative results being compared with control discs. By using this method, satisfactory log dose-reponse curves were obtained for bradykinin and histamine that followed the general trend of S - shaped curves [pt

    In three experiments in which rats were used as subjects, we developed an extinction procedure using a Morris pool. The animals were trained to find a hidden platform located at a fixed position and were then given extinction trials in which the platform was removed from the pool. When training and extinction were carried out in the same context and time was allowed to elapse between extinction and test, spontaneous recovery of learning was observed. On the other hand, those rats that received extinction in a context different from the one used for training failed to show spontaneous recovery of learning when tested in the extinction context after an interval of 96 h. However, they did show renewal of spatial learning when tested in the training context. These results show that extinction in the spatial domain behaves like extinction in standard conditioning preparations.

    Alternative concepts for increasing basin capabilities for storage of spent fuel at the Morris Operation have been defined in a series of simplified flow diagrams and equipment schematics. Preliminary concepts have been outlined for (1) construction alternatives for an add-on basin, (2) high-density baskets for storage of fuel bundles or possible consolidated fuel rods in the existing or add-on basins, (3) modifications to the existing facility for increasing cask handling and fuel receiving capabilities and (4) accumulation, treatment and disposal of radwastes from storage operations. Preliminary capital and operating costs have been prepared and resource and schedule requirements for implementing the concepts have been estimated. The basin expansion alternatives would readily complement potential dry storage projects at the site in an integrated multi-stage program that could provide a total storage capacity of up to 7000 tonnes of spent fuel

  6. Remembering Places in Space: A Human Analog Study of the Morris Water Maze

    Science.gov (United States)

    Fitting, Sylvia; Allen, Gary L.; Wedell, Douglas H.

    We conducted a human analog study of the Morris Water Maze, with individuals indicating a remembered location in a 3 m diameter arena over different intervals of time and with different memory loads. The primary focus of the study was to test a theory of how varying cue location and number of cues affects memory for spatial location. As expected, memory performance, as measured by proximity to the actual location, was negatively affected by increasing memory load, increasing delay interval, and decreasing the number of cues. As memory performance decremented, bias effects increased and were in accordance with the cue-based memory model described by Fitting, Wedell and Allen (2005). Specifically, remembered locations were biased toward the nearest cue and error decreased with more cues. These results demonstrate that localization processes that apply to small two-dimensional task fields may generalize to a larger traversable task field.

    Transient behavior is thought to play an integral role in brain functionality. Numerical simulations of the firing activity of diffusively coupled, excitable Morris-Lecar neurons reveal transient spatiotemporal chaos in the parameter regime below the saddle-node on invariant circle bifurcation point. The neighborhood of the chaotic saddle is reached through perturbations of the rest state, in which few initially active neurons at an effective spatial distance can initiate spatiotemporal chaos. The system escapes from the neighborhood of the chaotic saddle to either the rest state or to a state of pulse propagation. The lifetime of the chaotic transients is manipulated in a statistical sense through a singular application of a synchronous perturbation to a group of neurons.

    Reuter-Lorenz, Patricia A; Cooke, Katherine A

    2016-09-01

    In this review we provide a broad overview of major trends in the cognitive neuroscience of aging and illustrate their roots in the pioneering ideas and discoveries of Morris Moscovitch and his close collaborators, especially Gordon Winocur. These trends include an on-going focus on the specific and dissociable contributions of medial temporal and frontal lobe processes to cognitive aging, especially in the memory domain, the role of individual variability stemming from different patterns of underlying neural decline, the possibility of compensatory neural and cognitive influences that alter the expression of neurobiological aging, and the investigation of lifestyle and psychosocial factors that affect plasticity and may contribute to the rate and level of neurocognitive decline. These prescient ideas, evident in the early work of Moscovitch and Winocur, continue to drive on-going research efforts in the cognitive neuroscience of aging. Copyright © 2016 Elsevier Ltd.

    Full Text Available Background: Human parvovirus B19 (HPV-B19 is the etiologic agent of erythema infectiosum, of transient aplastic crises in individuals with underlying chronic hemolytic disorders, and of chronic pure red cell aplasia in immunocompromised individuals. Case report. We describe a 14-year-old girl with long-standing Evans syndrome, who presented with severe anemia, reticulocytopenia and thromocytopenia. A bone marrow aspirate revealed severe erythroid hypoplasia along with presence of giant pronormoblasts, while serological studies and real-time PCR of whole blood were positive for acute parvovirus B19 infection. The patient was initially managed with corticosteroids, but both cytopenias resolved only after administration of intravenous gamma globulin 0.8g/kg. Conclusion: Acute parvovirus B19 infection should be suspected in patients with immunologic diseases, who present with reticulocytopenic hemolytic anemia and thrombocytopenia. In this setting, intravenous gamma globulin is effective for both cytopenias.

    Progress on the Disruption Simulation Code (DSC-3D) development and benchmarking will be presented. The DSC-3D is one-fluid nonlinear time-dependent MHD code, which utilizes fully 3D toroidal geometry for the first wall, pure vacuum and plasma itself, with adaptation to the moving plasma boundary and accurate resolution of the plasma surface current. Suppression of fast magnetosonic scale by the plasma inertia neglecting will be demonstrated. Due to code adaptive nature, self-consistent plasma surface current modeling during non-linear dynamics of the Vertical Displacement Event (VDE) is accurately provided. Separation of the plasma surface current on Evans and Hiro currents during simulation of fully developed VDE, then the plasma touches in-vessel tiles, will be discussed.

    2016-09-01

    Full Text Available Evans syndrome (ES is a rare hematological disease characterized by autoimmune hemolytic anemia, immune thrombocytopenia, and/or neutropenia, all of which may be seen simultaneously or subsequently. Thrombotic events in ES are uncommon. Furthermore, non-ST segment-elevation myocardial infarction (NSTEMI during ES is a very rare condition. Here, we describe a case of a 69-year-old female patient presenting with NSTEMI and ES. Revascularization via percutaneous coronary intervention (PCI was scheduled and performed. Hemopericardium and cardiac tamponade occurred 5 h after PCI, and urgent pericardiocentesis was performed. Follow-up was uneventful, and the patient was safely discharged. Early recognition and appropriate management of NSTEMI is crucial to prevent morbidity and mortality. Coexistence of NSTEMI and ES, which is associated with increased bleeding risk, is a challenging scenario and these patients should be closely monitored in order to achieve early recognition and treatment of complications.

  14. On the behavior of Bronsted-Evans-Polanyi Relations for Transition Metal Oxides

    Energy Technology Data Exchange (ETDEWEB)

    Vojvodic, Aleksandra

    2011-08-22

    Versatile Broensted-Evans-Polanyi (BEP) relations are found from density functional theory for a wide range of transition metal oxides including rutiles and perovskites. For oxides, the relation depends on the type of oxide, the active site and the dissociating molecule. The slope of the BEP relation is strongly coupled to the adsorbate geometry in the transition state. If it is final state-like the dissociative chemisorption energy can be considered as a descriptor for the dissociation. If it is initial state-like, on the other hand, the dissociative chemisorption energy is not suitable as descriptor for the dissociation. Dissociation of molecules with strong intramolecular bonds belong to the former and molecules with weak intramolecular bonds to the latter group. We show, for the prototype system La-perovskites, that there is a 'cyclic' behavior in the transition state characteristics upon change of the active transition metal of the oxide.

    Full Text Available Abstract Background Hyperglycemia leads to cardiac oxidative stress and an imbalance in glucose homeostasis. Diabetic cardiomyopathy is characterised by cardiac hypertrophy and fibrosis. However, the underlying mechanisms of diabetic cardiomyopathy are not fully understood. This study aimed to investigate the effects of alpha-lipoic acid (ALA on cardiac energy metabolism, antioxidant effect, and fibrosis in the hearts of Otsuka Long-Evans Tokushima fatty (OLETF rats. Methods Animals were separated into non-diabetic Long-Evans Tokushima Otsuka (LETO rats and diabetes-prone OLETF rats with or without ALA (200 mg/kg/day administration for 16 weeks. Diabetic cardiomyopathy was assessed by staining with Sirius Red. The effect of ALA on AMPK signalling, antioxidant enzymes, and fibrosis-related genes in the heart of OLETF rats were performed by Western blot analysis or immunohistochemistry. Results Western blot analysis showed that cardiac adenosine monophosphate-activated kinase (AMPK signalling was lower in OLETF rats than in LETO rats, and that ALA treatment increased the signalling in OLETF rats. Furthermore, the low antioxidant activity in OLETF rats was increased by ALA treatment. In addition to increased Sirius red staining of collagen deposits, transforming growth factor-β1 (TGF-β1 and connective tissue growth factor (CTGF were expressed at higher levels in OLETF rat hearts than in LETO rat hearts, and the levels of these factors were decreased by ALA. Conclusions ALA enhances AMPK signalling, antioxidant, and antifibrogenic effect. Theses findings suggest that ALA may have beneficial effects in the treatment of diabetic cardiomyopathy.

  17. How Philip Morris built Marlboro into a global brand for young adults: implications for international tobacco control.

    Hafez, N; Ling, P M

    2005-08-01

    To describe Philip Morris' global market research and international promotional strategies targeting young adults. Analysis of previously secret tobacco industry documents. Philip Morris pursued standardised market research and strategic marketing plans in different regions throughout the world using research on young adults with three principle foci: lifestyle/psychographic research, brand studies, and advertising/communication effectiveness. Philip Morris identified core similarities in the lifestyles and needs of young consumers worldwide, such as independence, hedonism, freedom, and comfort. In the early 1990s Philip Morris adopted standardised global marketing efforts, creating a central advertising production bank and guidelines for brand images and promotions, but allowing regional managers to create regionally appropriate individual advertisements. Values and lifestyles play a central role in the global marketing of tobacco to young adults. Worldwide counter marketing initiatives, coupled with strong, coherent global marketing policies such as the Framework Convention on Tobacco Control, are needed to break associations between young adult values and tobacco brands. As globalisation promotes the homogenisation of values and lifestyles, tobacco control messages that resonate with young adults in one part of the world may appeal to young adults in other countries. Successful tobacco control messages that appeal to young people, such as industry denormalisation, may be expanded globally with appropriate tailoring to appeal to regional values.

    2013-12-01

    Although extensive investigation has revealed that an astrocyte-specific protein aquaporin-4 (AQP4) participates in regulating synaptic plasticity and memory, a functional relationship between AQP4 and learning processing has not been clearly established. This study was designed to test our hypothesis that AQP4 modulates the aversive motivation in Morris water maze (MWM). Using hidden platform training, we observed that AQP4 KO mice significantly decreased their swimming velocity compared with wild-type (WT) mice. To test for a relationship between velocities and escape motivation, we removed the platform and subjected a new group of mice similar to the session of hidden platform training. We found that KO mice exhibited a gradual reduction in swimming velocity, while WT mice did not alter their velocity. In the subsequent probe trial, KO mice after no platform training significantly decreased their mean velocity compared with those KO mice after hide platform training. However, all of KO mice were not impaired in their ability to locate a visible, cued escape platform. Our findings, along with a previous report that AQP4 regulates memory consolidation, implicate a novel role for this glial protein in modulating the aversive motivation in spatial learning paradigm. © 2013 John Wiley & Sons Ltd.

    The present study was aimed at examining spatial learning and memory, in 33 men and 12 women with alcohol use disorder (AUD) undergoing ethanol detoxification, by using a virtual Morris task. As controls, we recruited 29 men and 10 women among episodic drinkers without a history of alcohol addiction or alcohol-related diseases. Elevated latency to the first movement in all trials was observed only in AUD persons; furthermore, control women had longer latencies compared with control men. Increased time spent to reach the hidden platform in the learning phase was found for women of both groups compared with men, in particular during trial 3. As predicted, AUD persons (more evident in men) spent less time in the target quadrant during the probe trial; however, AUD women had longer latencies to reach the platform in the visible condition during trials 6 and 7 that resulted in a greater distance moved. As for the probe trial, men of both groups showed increased virtual locomotion compared with the women of both groups. The present investigation confirms and extends previous studies showing (i) different gender responses in spatial learning tasks, (ii) some alterations due to alcohol addiction in virtual spatial learning, and (iii) differences between AUD men and AUD women in spatial-behaviour-related paradigms.

    Apoptosis has been described as an energy-consuming process. This combined in vivo/in vitro study investigated the effects of the antineoplastic agent gemcitabine on tumour metabolism and on the induction of apoptosis. Dynamic positron emission tomography (PET) measurements of fluorine-18 fluorodeoxyglucose (FDG) uptake were done in rats bearing Morris hepatoma prior to and after therapy with 90 mg gemcitabine/kg b.w. Furthermore, thymidine (TdR) incorporation into the DNA of these tumours was determined. In vitro measurements of FDG and TdR uptake were performed immediately and 24 h after the end of gemcitabine treatment, and the amount of apoptotic cells was determined using the TUNEL reaction. In vivo an increase in FDG transport and phosphorylation occurred early after gemcitabine treatment, although TdR incorporation into the DNA of the tumours declined. In vitro, an enhanced glucose transport, an increase in TdR uptake in the cytoplasm and a decrease in TdR incorporation in the nucleic acid fraction early after treatment occurred. Inhibition of glucose transport caused an increase in the amount of apoptotic cells. The increase in glucose uptake and TdR metabolism early after therapy is interpreted as a stress reaction of the tumour cells, protecting the cells from apoptosis during this early period after exposure to cytotoxic drugs like gemcitabine.

    The assessment of spatial cognitive learning in rodents is a central approach in neuroscience, as it enables one to assess and quantify the effects of treatments and genetic manipulations from a broad perspective. Although the Morris water maze (MWM) is a well-validated paradigm for testing spatial learning abilities, manual categorization of performance in the MWM into behavioral strategies is subject to individual interpretation, and thus to biases. Here we offer a support vector machine (SVM) - based, automated, MWM unbiased strategy classification (MUST-C) algorithm, as well as a cognitive score scale. This model was examined and validated by analyzing data obtained from five MWM experiments with changing platform sizes, revealing a limitation in the spatial capacity of the hippocampus. We have further employed this algorithm to extract novel mechanistic insights on the impact of members of the Toll-like receptor pathway on cognitive spatial learning and memory. The MUST-C algorithm can greatly benefit MWM users as it provides a standardized method of strategy classification as well as a cognitive scoring scale, which cannot be derived from typical analysis of MWM data.

    Stress and stress hormones are known to influence the function of the hippocampus, a brain structure critical for cognitive-map-based, allocentric spatial navigation. The caudate nucleus, a brain structure critical for stimulus-response-based, egocentric navigation, is not as sensitive to stress. Evidence for this comes from rodent studies, which show that acute stress or stress hormones impair allocentric, but not egocentric navigation. However, there have been few studies investigating the effect of acute stress on human spatial navigation, and the results of these have been equivocal. To date, no study has investigated whether acute stress can shift human navigational strategy selection between allocentric and egocentric navigation. The present study investigated this question by exposing participants to an acute psychological stressor (the Paced Auditory Serial Addition Task, PASAT), before testing navigational strategy selection in the Dual-Strategy Maze, a modified virtual Morris water maze. In the Dual-Strategy maze, participants can chose to navigate using a constellation of extra-maze cues (allocentrically) or using a single cue proximal to the goal platform (egocentrically). Surprisingly, PASAT stress biased participants to solve the maze allocentrically significantly more, rather than less, often. These findings have implications for understanding the effects of acute stress on cognitive function in general, and the function of the hippocampus in particular. Copyright © 2016 Elsevier Inc.

    The possibility that androgens contribute to the male advantage typically found on measures of spatial cognition has been investigated using a variety of approaches. To date, evidence to support the notion that androgens affect spatial cognition in healthy young adults is somewhat equivocal. The present study sought to clarify the association between testosterone (T) and spatial performance by extending measurements of androgenicity to include both measures of circulating T as well as an androgen receptor-specific genetic marker. The aims of this study were to assess the contributions of sex, T, and androgen receptor CAG repeat number (CAGr) on virtual Morris water task (vMWT) performance in a group of healthy young men and women. The hypothesis that men would outperform women on vMWT outcomes was supported. Results indicate that CAGr may interact with T to impact navigation performance and suggest that consideration of androgen receptor sensitivity is an important consideration in evaluating hormone-behavior relationships.

    Although effective spatial navigation requires memory for objects and locations, navigating a novel environment may also require considerable executive resources. The present study investigated associations between performance on the virtual Morris Water Task (vMWT), an analog version of a nonhuman spatial navigation task, and neuropsychological tests of executive functioning and spatial performance in 75 healthy young adults. More effective vMWT performance (e.g., lower latency and distance to reach hidden platform, greater distance in goal quadrant on a probe trial, fewer path intersections) was associated with better verbal fluency, set switching, response inhibition, and ability to mentally rotate objects. Findings also support a male advantage in spatial navigation, with sex moderating several associations between vMWT performance and executive abilities. Overall, we report a robust relationship between executive functioning and navigational skill, with some evidence that men and women may differentially recruit cognitive abilities when navigating a novel environment.

    Full Text Available We studied some of the characteristics of the improving effect of the non-specific adenosine receptor antagonist, caffeine, using an animal model of learning and memory. Groups of 12 adult male Wistar rats receiving caffeine (0.3-30 mg/kg, ip, in 0.1 ml/100 g body weight administered 30 min before training, immediately after training, or 30 min before the test session were tested in the spatial version of the Morris water maze task. Post-training administration of caffeine improved memory retention at the doses of 0.3-10 mg/kg (the rats swam up to 600 cm less to find the platform in the test session, P<=0.05 but not at the dose of 30 mg/kg. Pre-test caffeine administration also caused a small increase in memory retrieval (the escape path of the rats was up to 500 cm shorter, P<=0.05. In contrast, pre-training caffeine administration did not alter the performance of the animals either in the training or in the test session. These data provide evidence that caffeine improves memory retention but not memory acquisition, explaining some discrepancies among reports in the literature.

  10. Fiscal versus social responsibility: how Philip Morris shaped the public funds divestment debate

    Science.gov (United States)

    Wander, N; Malone, R E

    2006-01-01

    Calls for institutional investors to divest (sell off) tobacco stocks threaten the industry's share values, publicise its bad behaviour, and label it as a politically unacceptable ally. US tobacco control advocates began urging government investment and pension funds to divest as a matter of responsible social policy in 1990. Following the initiation of Medicaid recovery lawsuits in 1994, advocates highlighted the contradictions between state justice departments suing the industry, and state health departments expanding tobacco control programmes, while state treasurers invested in tobacco companies. Philip Morris (PM), the most exposed US company, led the divestment opposition, consistently framing the issue as one of responsible fiscal policy. It insisted that funds had to be managed for the exclusive interest of beneficiaries, not the public at large, and for high share returns above all. This paper uses tobacco industry documents to show how PM sought to frame both the rhetorical contents and the legal contexts of the divestment debate. While tobacco stock divestment was eventually limited to only seven (but highly visible) states, US advocates focused public attention on the issue in at least 18 others plus various local jurisdictions. This added to ongoing, effective campaigns to denormalise and delegitimise the tobacco industry, dividing it from key allies. Divestment as a delegitimisation tool could have both advantages and disadvantages as a tobacco control strategy in other countries. PMID:16728755

  11. Applications of the Morris water maze in translational traumatic brain injury research.

    2018-05-01

    Acquired traumatic brain injury (TBI) is frequently accompanied by persistent cognitive symptoms, including executive function disruptions and memory deficits. The Morris Water Maze (MWM) is the most widely-employed laboratory behavioral test for assessing cognitive deficits in rodents after experimental TBI. Numerous protocols exist for performing the test, which has shown great robustness in detecting learning and memory deficits in rodents after infliction of TBI. We review applications of the MWM for the study of cognitive deficits following TBI in pre-clinical studies, describing multiple ways in which the test can be employed to examine specific aspects of learning and memory. Emphasis is placed on dependent measures that are available and important controls that must be considered in the context of TBI. Finally, caution is given regarding interpretation of deficits as being indicative of dysfunction of a single brain region (hippocampus), as experimental models of TBI most often result in more diffuse damage that disrupts multiple neural pathways and larger functional networks that participate in complex behaviors required in MWM performance.

    Full Text Available Tomando como estudo de caso a monografia de Sharon Hutchinson sobre os nuer, o presente artigo explora os quiproquós do diálogo entre a antropologia contemporânea e os clássicos, procurando detetar certas genealogias invisíveis que remontam aos funcionalistas britânicos, e nomeadamente a Evans-Pritchard. Procede a um esbatimento de certas oposições explícitas entre o presente e o passado da antropologia, revelando que as noções clássicas perpassam de forma subterrânea o discurso daqueles que dizem rejeitá-las e que muitas das preocupações atuais já tinham expressão nas etnografias modernas. É demonstrado que as abordagens estáticas - como a de Evans-Pritchard - tinham uma componente histórica e que a antropologia social britânica teve as suas respostas teóricas e metodológicas para as transformações dos contextos africanos sob domínio colonial.Through the reading of Sharon Hutchinson’s monograph on the Nuer, this article explores the misunderstandings between contemporary anthropology and the modern classics. It tries to identify invisible genealogies that go back to the British functionalists, particularly to Evans-Pritchard, and minimizes the explicit oppositions between the present and the past of anthropology. It reveals that some classical notions are detectable in non-explicit ways among those who claim to reject them and, at the same time, that contemporary concerns have their roots in modern ethnographies. The author shows that static approaches - as the one by Evans-Pritchard on the Nuer - had a historical meaning and recalls that British social anthropology had its own theoretical and methodological answers to the transformations of African contexts under colonial rule.

  14. Of mice and men: evolution and the socialist utopia. William Morris, H.G. Wells, and George Bernard Shaw.

    Hale, Piers J

    2010-01-01

    During the British socialist revival of the 1880s competing theories of evolution were central to disagreements about strategy for social change. In News from Nowhere (1891), William Morris had portrayed socialism as the result of Lamarckian processes, and imagined a non-Malthusian future. H.G. Wells, an enthusiastic admirer of Morris in the early days of the movement, became disillusioned as a result of the Malthusianism he learnt from Huxley and his subsequent rejection of Lamarckism in light of Weismann's experiments on mice. This brought him into conflict with his fellow Fabian, George Bernard Shaw, who rejected neo-Darwinism in favour of a Lamarckian conception of change he called "creative evolution."

    Full Text Available Evans syndrome (ES is a rare autoimmune disorder whose long-term follow-up characteristics are unknown. Patients under 18 at the time of diagnosis of a first autoimmune cytopenia have been included since 2004 in a national prospective observational cohort. In 2014, 156 children diagnosed between 1981 and 2014 with ES, were analyzed. The median age at initial cytopenia was 5.4 (0.2-17.2 years old. For 85 sequential cases, the median delay between the episodes of AIHA and ITP was 2.4 years (0.1–16.3. The median follow-up since ES diagnosis was 6.5 years (0.1-28.8. ES revealed underlying diseases in 10% of children; in 60% of patients, various associated immune manifestations were observed, and ES remained primary in 30%. Five-year ITP and AIHA relapse-free survival were respectively 25% and 61%. In all, 69% of children required one or more than one second-line immune treatment and 15 patients (10% died at a median age of 14.3 years (1.7-28.1.This national work provides the first consistent clinical description for ES and underscores the high percentage of associated immune manifestations, the long-term complications, and treatment toxicities. Current challenges include the identification of underlying genetic immune dysregulations and better characterization of subgroups of patients and of second-line therapy strategies.

    2013-05-01

    Dual-process theories of higher order cognition (DPTs) have been enjoying much success, particularly since Kahneman's 2002 Nobel prize address and recent book Thinking, Fast and Slow (2009). Historically, DPTs have attempted to provide a conceptual framework that helps classify and predict differences in patterns of behavior found under some circumstances and not others in a host of reasoning, judgment, and decision-making tasks. As evidence has changed and techniques for examining behavior have moved on, so too have DPTs. Killing two birds with one stone, Evans and Stanovich (2013, this issue) respond to five main criticisms of DPTs. Along with addressing each criticism in turn, they set out to clarify the essential defining characteristics that distinguish one form of higher order cognition from the other. The aim of this commentary is to consider the defining characteristics of Type 1 and Type 2 processing that have been proposed and to suggest that the evidence can be taken to support quantitative differences rather than qualitatively distinct processes. © The Author(s) 2013.

    2014-10-01

    The recently created numerical code VDE for simulations of vertical instability in tokamaks is presented. The numerical scheme uses the Tokamak MHD model, where the plasma inertia is replaced by the friction force, and an adaptive grid numerical scheme. The code reproduces well the surface currents generated at the plasma boundary by the instability. Five regimes of the vertical instability are presented: (1) Vertical instability in a given plasma shaping field without a wall; (2) The same with a wall and magnetic flux ΔΨ|plX< ΔΨ|Xwall(where X corresponds to the X-point of a separatrix); (3) The same with a wall and magnetic flux ΔΨ|plX> ΔΨ|Xwall; (4) Vertical instability without a wall with a tile surface at the plasma path; (5) The same in the presence of a wall and a tile surface. The generation of negative Hiro currents along the tile surface, predicted earlier by the theory and measured on EAST in 2012, is well-reproduced by simulations. In addition, the instability generates the force-free Evans currents at the free plasma surface. The new pattern of reconnection of the plasma with the vacuum magnetic field is discovered.

    Sorgner, Helene

    2016-06-01

    This paper compares Feyerabend's arguments in Science in a Free Society to the controversial theory of expertise proposed by Harry Collins and Robert Evans as a Third Wave of Science Studies. Is the legitimacy of democratic decisions threatened by the unquestioned authority of scientific advice? Or does, on the contrary, science need protection from too much democratic participation in technical decisions? Where Feyerabend's political relativism envisions democratic society as inherently pluralist and demands equal contribution of all traditions and worldviews to public decision-making, Collins and Evans hold a conception of elective modernism, defending the reality and value of technical expertise and arguing that science deserves a privileged status in modern democracies, because scientific values are also democratic values. I will argue that Feyerabend's political relativism provides a valuable framework for the evaluation of Collins' and Evans' theory of expertise. By constructing a dialog between Feyerabend and this more recent approach in Science and Technology Studies, the aim of this article is not only to show where the two positions differ and in what way they might be reconciled, but also how Feyerabend's philosophy provides substantial input to contemporary debate.

    Spatial navigation is impaired in early stages of Alzheimers disease (AD), and may be a defining behavioral marker of preclinical AD. Nevertheless, limitations of diagnostic criteria for AD and within animal models of AD make characterization of preclinical AD difficult. A new rat model (TgF344-AD) of AD overcomes many of these limitations, though spatial navigation has not been comprehensively assessed. Using the hidden and cued platform variants of the Morris water task, a longitudinal asse...

    Full Text Available Background Beginning in the 1980s, tobacco control efforts shifted from school-based and clinic-based education about the dangers of smoking to direct confrontation of the tobacco industry. But the industry also evolved by developing innovative promotional campaigns, adopting new corporate identities, and forging alliances with other industries and charitable organizations. Methods To document the extent of the commercial, civic, political, academic, military,and cultural ties cultivated by the world´s largest cigarette manufacturer, Philip Morris, a continuous, 35-year ethnographic analysis was conducted, involving daily monitoring of the global business press; monthly review of tobacco industry trade publications; scrutiny of annual company reports; and attendance at 20 shareholders´ meetings, four international tobacco industry trade expositions, and over 200 sports, arts, and ethnic minority events sponsored by the company. Results 48 Philip Morris manufacturing facilities in 32 countries produce more than 800 billion cigarettes a year for 180 markets..A pioneer in sponsoring popular programs on the new medium of television in the 1950s; the company circumvented the 1971 ban on TV cigarette advertising by creating sporting events that were internationally televised.

    To evaluate reliability and construct validity of the Norwegian versions of the Roland Morris Disability Questionnaire and the modified Oswestry Disability Index. Translation of two functional status questionnaires and a cross-sectional study of measurement properties. The questionnaires were translated and back-translated following the Guillemin criteria. The Norwegian versions were tested for 55 patients with acute low back pain and 50 patients with chronic low back pain. Test-retest with a 2-day interval was performed in a subsample of 28 patients from the chronic sample. Reliability was assessed by repeatability according to Bland and Altman, intraclass coefficient and coefficient of variation. Internal consistency was assessed by Cronbach's alpha. Concurrent construct validity was assessed with correlations between the questionnaires and the SF-36, Disability Rating Index and pain intensity. Repeatability of the Roland Morris Disability Questionnaire was 4 points, coefficient of variation 15% and intraclass correlation coefficient 0.89, and of the modified Oswestry Disability Index 11, 12% and 0.88, respectively. Internal consistency was 0.94 for both questionnaires. The questionnaires correlated highly with the physical functioning scale of SF-36, moderately with pain, and low with mental scales of the SF-36. The reliability and construct validity of the Norwegian versions of the Roland Morris Disability Questionnaire and the modified Oswestry Disability Index are acceptable for assessing functional status of Norwegian-speaking patients with low back pain.

  3. Technical Note: Method of Morris effectively reduces the computational demands of global sensitivity analysis for distributed watershed models

    Full Text Available The increase in spatially distributed hydrologic modeling warrants a corresponding increase in diagnostic methods capable of analyzing complex models with large numbers of parameters. Sobol' sensitivity analysis has proven to be a valuable tool for diagnostic analyses of hydrologic models. However, for many spatially distributed models, the Sobol' method requires a prohibitive number of model evaluations to reliably decompose output variance across the full set of parameters. We investigate the potential of the method of Morris, a screening-based sensitivity approach, to provide results sufficiently similar to those of the Sobol' method at a greatly reduced computational expense. The methods are benchmarked on the Hydrology Laboratory Research Distributed Hydrologic Model (HL-RDHM over a six-month period in the Blue River watershed, Oklahoma, USA. The Sobol' method required over six million model evaluations to ensure reliable sensitivity indices, corresponding to more than 30 000 computing hours and roughly 180 gigabytes of storage space. We find that the method of Morris is able to correctly screen the most and least sensitive parameters with 300 times fewer model evaluations, requiring only 100 computing hours and 1 gigabyte of storage space. The method of Morris proves to be a promising diagnostic approach for global sensitivity analysis of highly parameterized, spatially distributed hydrologic models.

    2009-01-01

    The occurrence of autoimmune hemolytic anemia and immune thrombocytopenia in the absence of a known underlying cause led to the diagnosis of Evans syndrome in a 9 month old male. Subsequently, a similar diagnosis was made in two siblings (a 3 year old boy and a 1 day old girl). The 9 month old had a chronic course with exacerbations. He was treated with steroids, intravenous immunoglobulin and colchiccine with a variable response. He died of congestive heart failure at the age of 8 years. The brother's disease course was one of remission and exacerbation. With time, remissions were prolonged and paralleled an improvement in joint hypermobility. The sister died of sepsis after a chronic course with severe exacerbattions. Only two families with Evans syndrome have been reported in the English medical literature. In one report (in a Saudi Arab family), the disease was associated with hereditary spastic paraplegia. (author)

    Cross-sectional design. To explore (1) the factor structure of the Roland-Morris Disability Questionnaire (RMDQ), (2) whether there is a dominant factor, and (3) whether the potential factors are unique predictors of other aspects related to back pain. The RMDQ is one of the most recommended back-specific questionnaires assessing disability. The RMDQ is scored as a unidimensional scale summarizing answers to all 24 questions (Yes/No) regarding daily life functioning. However, there are indications that the scale is multidimensional. Patients (n = 457; age, 18-60 yr) with 8 to 12 weeks of back pain filled in questionnaires assessing subjective health complaints, emotional distress, instrumental and emotion-focused coping, and fear voidance behavior at baseline. A total of 371 patients (81.7%) filled in the RMDQ. Exploratory factor analysis was used to examine the factor structure of RMDQ items. Multiple regression analyses were used to assess whether the derived factors predicted relevant problems in back pain differently. Exploratory factor analysis showed indices of model fit for a 3-factor solution after removing 2 items because of low prevalence (19 and 24). Two items were removed because of cross-loadings and low loadings (2 and 22). No support for a dominant factor was found as the 3 factors were only moderately correlated (r = 0.34-0.40), and the ratio between the first and second eigenvalue was 2.6, not supporting essential unidimensionality. "Symptoms" were the factor that most strongly predicted subjective health complaints, whereas "avoidance of activity and participation" predicted fear avoidance behavior, instrumental and emotional coping. "Limitation in daily activities" did not predict any of these variables. The main findings of our study are that the RMDQ consists of 3 independent factors, and not 1 dominant factor as suggested previously. We think the time is now ripe to start treating and scoring the RMDQ as a multidimensional scale. N/A.

  7. Molecular mechanisms for the destabilization and restabilization of reactivated spatial memory in the Morris water maze

    2011-02-01

    Full Text Available Abstract Background Memory retrieval is not a passive process. Recent studies have shown that reactivated memory is destabilized and then restabilized through gene expression-dependent reconsolidation. Molecular studies on the regulation of memory stability after retrieval have focused almost exclusively on fear memory, especially on the restabilization process of the reactivated fear memory. We previously showed that, similarly with fear memories, reactivated spatial memory undergoes reconsolidation in the Morris water maze. However, the underlying molecular mechanisms by which reactivated spatial memory is destabilized and restabilized remain poorly understood. In this study, we investigated the molecular mechanism that regulates the stability of the reactivated spatial memory. Results We first showed that pharmacological inactivation of the N-methyl-D-aspartate glutamate receptor (NMDAR in the hippocampus or genetic inhibition of cAMP-responsible element binding protein (CREB-mediated transcription disrupted reactivated spatial memory. Finally, we showed that pharmacological inhibition of cannabinoid receptor 1 (CB1 and L-type voltage gated calcium channels (LVGCCs in the hippocampus blocked the disruption of the reactivated spatial memory by the inhibition of protein synthesis. Conclusions Our findings indicated that the reactivated spatial memory is destabilized through the activation of CB1 and LVGCCs and then restabilized through the activation of NMDAR- and CREB-mediated transcription. We also suggest that the reactivated spatial memory undergoes destabilization and restabilization in the hippocampus, through similar molecular processes as those for reactivated contextual fear memories, which require CB1 and LVGCCs for destabilization and NMDAR and CREB for restabilization.

    2008-12-23

    This paper examines the efforts of consultants affiliated with Philip Morris (PM), the world's leading transnational tobacco corporation, to influence scientific research and training in Thailand via the Chulabhorn Research Institute (CRI). A leading Southeast Asian institute for environmental health science, the CRI is headed by Professor Dr. Her Royal Highness Princess Chulabhorn, the daughter of the King of Thailand, and it has assumed international significance via its designation as a World Health Organization (WHO) Collaborating Centre in December 2005. This paper analyses previously confidential tobacco industry documents that were made publicly available following litigation in the United States. PM documents reveal that ostensibly independent overseas scientists, now identified as industry consultants, were able to gain access to the Thai scientific community. Most significantly, PM scientist Roger Walk has established close connections with the CRI. Documents indicate that Walk was able to use such links to influence the study and teaching of environmental toxicology in the institute and to develop relations with key officials and local scientists so as to advance the interests of PM within Thailand and across Asia. While sensitivities surrounding royal patronage of the CRI make public criticism extremely difficult, indications of ongoing involvement by tobacco industry consultants suggest the need for detailed scrutiny of such relationships. The establishment of close links with the CRI advances industry strategies to influence scientific research and debate around tobacco and health, particularly regarding secondhand smoke, to link with academic institutions, and to build relationships with national elites. Such strategies assume particular significance in the national and regional contexts presented here amid the globalisation of the tobacco pandemic. From an international perspective, particular concern is raised by the CRI's recently awarded status

    The present study was designed to determine if male physiology and male reproductive behavior predict reproductive success in Long-Evans rats. Mating behavior was observed in sexually naïve, naturally cycling female rats during behavioral estrous that were given the opportunity to mate with two males simultaneously. DNA analysis of offspring born following these mating encounters was used to identify the paternity of each pup. In order to assess the effect of mate choice during these mating encounters on reproductive success, one male rat in each pair was categorized as the preferred mate if the female spent more time (>50%) with him during the mating test of the present study. Furthermore, each male in the pairs was categorized as "attractive" or "non-attractive" by computing the number of females that preferred each male across many mating tests. Similar to results reported in Lovell et al. (2007), during 76% of these mating tests the same male rat in each pair was preferred by different female rats. Overall attractiveness of individual male rats predicted reproductive success in the present study. Interestingly, "attractive" males sired significantly FEWER pups than "non-attractive" males. Neither behavioral (e.g., latency to first sexual stimulation, number of sexual stimulations) nor physiological measures (e.g., body weight, urinary testosterone levels) of male rats predicted their reproductive success. In conclusion, the present results indicate that certain features of some males are more attractive to females, but attractive males are at a reproductive disadvantage (as measured by the number of pups sired). Although basal urinary testosterone levels did not differ between males that sired the majority of pups in a litter and males that sired few or none of the pups in a litter, aggression and/or other physiological measures of fertility (e.g., penile reflexes) may differ between males that are attractive to females and those that have a reproductive

    The Long-Evans Cinnamon (LEC) rat is a mutant animal model for Wilson's disease. It is known that an abnormal accumulation of Cu and Fe in the liver and low concentrations of both ceruloplasmin and Cu in the serum occur in these rats. The accumulation of Cu is explained by the defective expression of the Cu-transporting P-type ATPase gene, homologous to the gene for Wilson's disease (ATP7B). The aim of this work was to clarify the action mechanism of Zn, and to verify the role that this metal plays in LEC rats in short-term treatment experiments (1 and 2 weeks) on concentrations of Cu, Zn, Fe, metallothionein (MT), 8-hydroxy-2'-deoxyguanosine (oh{sup 8}dG) and on the activity of antioxidant enzymes. It is well known that Zn induces MT and has the ability to prevent redox-active metals, Cu and Fe, binding to and causing oxidative damage at active sites of Zn metalloenzymes and nonspecific binding sites on proteins. Zn administration reduces Cu and Fe transport from mucosal to serosal intestinal sides through competitive mechanisms. Our findings show that treatment with zinc acetate increases tissue Zn and MT contents and decreases Cu and Fe concentrations in the liver and kidneys, even if hepatic Zn and MT concentrations decrease with treatment period. Induction of MT synthesis by Zn contributes to the reduction in free radicals produced by Cu and Fe. We also observed that the superoxide dismutase (SOD)activity in liver decreases with treatment duration in association with the Cu and Fe liver decrease. However, the SOD activity in kidney increases in untreated rats at 2 weeks relative to those untreated for 1 week. (orig.)

    Very low frequency (VLF) electromagnetic signals from navigational transmitters propagate worldwide in the Earth-ionosphere waveguide formed by the Earth and the electrically conducting lower ionosphere. Changes in the signal properties are signatures of variations in the conductivity of the reflecting boundary of the lower ionosphere which is located in the mesosphere and lower thermosphere, and their analysis is, therefore, a way to study processes in these remote regions. Here we present a study on amplitude perturbations of local origin on the VLF transmitter signals (NPM, NLK, NAA, and JJI) observed during tropical cyclone (TC) Evan, 9-16 December 2012 when TC was in the proximity of the transmitter-receiver links. We observed a maximum amplitude perturbation of 5.7 dB on JJI transmitter during 16 December event. From Long Wave Propagation Capability model applied to three selected events we estimate a maximum decrease in the nighttime D region reference height (H') by 5.2 km (13 December, NPM) and maximum increase in the daytime D region H' by 6.1 km and 7.5 km (14 and 16 December, JJI). The results suggest that the TC caused the neutral densities of the mesosphere and lower thermosphere to lift and sink (bringing the lower ionosphere with it), an effect that may be mediated by gravity waves generated by the TC. The perturbations were observed before the storm was classified as a TC, at a time when it was a tropical depression, suggesting the broader conclusion that severe convective storms, in general, perturb the mesosphere and the stratosphere through which the perturbations propagate.

    Eating disorders are associated with impaired decision-making and dysfunctional reward-related neurochemistry. The present study examined the potential contributions of dopamine and opioid signaling to these processes using two different decision-making tasks. In one task, Long Evans Rats chose between working for a preferred food (high-carbohydrate banana-flavored sucrose pellets) by lever pressing on a progressive-ratio schedule of reinforcement vs. obtaining less preferred laboratory chow that was concurrently available. In a second (effort-free) task, rats chose between the same two reinforcers when they were both available freely. Rats were trained in these tasks before receiving haloperidol (0.00, 0.05, 0.10mg/kg, intraperitoneally (i.p.)) or naloxone (0.0, 1.5, 3.0mg/kg, i.p.). In the first task, haloperidol decreased breakpoint, lever presses, number of reinforcers earned, and increased chow intake, whereas naloxone decreased breakpoint and number of reinforcers earned but had no effect on chow consumption. In the effort-free task, haloperidol reduced intakes of both foods without affecting preference, whereas naloxone selectively reduced the consumption of banana-pellets. The present findings support converging evidence suggesting that DA signaling affects processes more closely related to appetitive motivation, leaving other components of motivation unchanged. By contrast, opioid signaling appears to mediate aspects of hedonic feeding by selectively altering intakes of highly palatable foods. For preferred foods, both appetitive and consummatory aspects of food intake were altered by opioid receptor antagonism. Our findings argue against a general suppression of appetite by either compound, as appetite manipulations have been shown to unselectively alter intakes of both types of food regardless of the task employed.

  14. Ethanol seeking by Long Evans rats is not always a goal-directed behavior.

    Regina A Mangieri

    Full Text Available Two parallel and interacting processes are said to underlie animal behavior, whereby learning and performance of a behavior is at first via conscious and deliberate (goal-directed processes, but after initial acquisition, the behavior can become automatic and stimulus-elicited (habitual. With respect to instrumental behaviors, animal learning studies suggest that the duration of training and the action-outcome contingency are two factors involved in the emergence of habitual seeking of "natural" reinforcers (e.g., sweet solutions, food or sucrose pellets. To rigorously test whether behaviors reinforced by abused substances such as ethanol, in particular, similarly become habitual was the primary aim of this study.Male Long Evans rats underwent extended or limited operant lever press training with 10% sucrose/10% ethanol (10S10E reinforcement (variable interval (VI or (VR ratio schedule of reinforcement, or with 10% sucrose (10S reinforcement (VI schedule only. Once training and pretesting were complete, the impact of outcome devaluation on operant behavior was evaluated after lithium chloride injections were paired with the reinforcer, or unpaired 24 hours later. After limited, but not extended instrumental training, lever pressing by groups trained under VR with 10S10E and under VI with 10S was sensitive to outcome devaluation. In contrast, responding by both the extended and limited training 10S10E VI groups was not sensitive to ethanol devaluation during the test for habitual behavior.Operant behavior by rats trained to self-administer an ethanol-sucrose solution showed variable sensitivity to a change in the value of ethanol, with relative insensitivity developing sooner in animals that received time-variable ethanol reinforcement during training sessions. One important implication, with respect to substance abuse in humans, is that initial learning about the relationship between instrumental actions and the opportunity to consume ethanol

    Full Text Available This paper examines the efforts of consultants affiliated with Philip Morris (PM, the world's leading transnational tobacco corporation, to influence scientific research and training in Thailand via the Chulabhorn Research Institute (CRI. A leading Southeast Asian institute for environmental health science, the CRI is headed by Professor Dr. Her Royal Highness Princess Chulabhorn, the daughter of the King of Thailand, and it has assumed international significance via its designation as a World Health Organization (WHO Collaborating Centre in December 2005.This paper analyses previously confidential tobacco industry documents that were made publicly available following litigation in the United States. PM documents reveal that ostensibly independent overseas scientists, now identified as industry consultants, were able to gain access to the Thai scientific community. Most significantly, PM scientist Roger Walk has established close connections with the CRI. Documents indicate that Walk was able to use such links to influence the study and teaching of environmental toxicology in the institute and to develop relations with key officials and local scientists so as to advance the interests of PM within Thailand and across Asia. While sensitivities surrounding royal patronage of the CRI make public criticism extremely difficult, indications of ongoing involvement by tobacco industry consultants suggest the need for detailed scrutiny of such relationships.The establishment of close links with the CRI advances industry strategies to influence scientific research and debate around tobacco and health, particularly regarding secondhand smoke, to link with academic institutions, and to build relationships with national elites. Such strategies assume particular significance in the national and regional contexts presented here amid the globalisation of the tobacco pandemic. From an international perspective, particular concern is raised by the CRI's recently

    The possibility of using deep brain stimulation (DBS) for memory enhancement has recently been reported, but the precise underlying mechanisms of its effects remain unknown. Our previous study suggested that spatial memory improvement by medial septum (MS)-DBS may be associated with cholinergic regulation and neurogenesis. However, the affected stage of memory could not be distinguished because the stimulation was delivered during the execution of all memory processes. Therefore, this study was performed to determine the stage of memory affected by MS-DBS. Rats were administered 192 IgG-saporin to lesion cholinergic neurons. Stimulation was delivered at different times in different groups of rats: 5 days before the Morris water maze test (pre-stimulation), 5 days during the training phase of the Morris water maze test (training-stimulation), and 2 h before the Morris water maze probe test (probe-stimulation). A fourth group of rats was lesioned but received no stimulation. These four groups were compared with a normal (control) group. The most effective memory restoration occurred in the pre-stimulation group. Moreover, the pre-stimulation group exhibited better recall of the platform position than the other stimulation groups. An increase in the level of brain derived neurotrophic factor (BDNF) was observed in the pre-stimulation group; this increase was maintained for 1 week. However, acetylcholinesterase activity in the pre-stimulation group was not significantly different from the lesion group. Memory impairment due to cholinergic denervation can be improved by DBS. The improvement is significantly correlated with the up-regulation of BDNF expression and neurogenesis. Based on the results of this study, the use of MS-DBS during the early stage of disease may restore spatial memory impairment.

    Spatiotemporal chaos collapses to either a rest state or a propagating pulse solution in a ring network of diffusively coupled, excitable Morris-Lecar neurons. Weak excitatory synapses can increase the Lyapunov exponent, expedite the collapse, and promote the collapse to the rest state rather than the pulse state. A single traveling pulse solution may no longer be asymptotic for certain combinations of network topology and (weak) coupling strengths, and initiate spatiotemporal chaos. Multiple pulses can cause chaos initiation due to diffusive and synaptic pulse-pulse interaction. In the presence of chaos initiation, intermittent spatiotemporal chaos exists until typically a collapse to the rest state.

    Full Text Available Abstract Background Phytoestrogens derived from soy foods (or isoflavones have received prevalent usage due to their 'health benefits' of decreasing: a age-related diseases, b hormone-dependent cancers and c postmenopausal symptoms. However, little is known about the influence of dietary phytoestrogens on regulatory behaviors, such as food and water intake, metabolic hormones and neuroendocrine parameters. This study examined important hormonal and metabolic health issues by testing the hypotheses that dietary soy-derived isoflavones influence: 1 body weight and adipose deposition, 2 food and water intake, 3 metabolic hormones (i.e., leptin, insulin, T3 and glucose levels, 4 brain neuropeptide Y (NPY levels, 5 heat production [in brown adipose tissue (BAT quantifying uncoupling protein (UCP-1 mRNA levels] and 6 core body temperature. Methods This was accomplished by conducting longitudinal studies where male Long-Evans rats were exposed (from conception to time of testing or tissue collection to a diet rich in isoflavones (at 600 micrograms/gram of diet or 600 ppm vs. a diet low in isoflavones (at approximately 10–15 micrograms/gram of diet or 10–15 ppm.

    Chronic stress during adolescence is related to increased prevalence of anxiety disorders and alcohol use disorders in humans. This phenotype has been consistently recapitulated in animal models with male subjects, but models using female subjects are fewer. The aim of these studies was to test the hypothesis that chronic social instability (CSI) during adolescence engenders increased anxiety-like behavior, increased corticosterone, and greater ethanol intake and/or preference than control groups in male and female rats. A chronic social instability (CSI) procedure was conducted in separate cohorts of female and male adolescent Long Evans rats. CSI included daily social isolation for 1h, and then pair housing with a novel cage mate for 23h until the next 1h isolation period from PND 30-46. Control groups included social stability (SS), chronic isolation (ISO), and acute social instability (aSI). At PND 49-50, anxiety-like behavior was assessed on the elevated plus maze, and on PND 51 tails bloods were obtained for determination of corticosterone (CORT) levels. This was followed by 4weeks of ethanol drinking in a home cage intermittent access ethanol drinking paradigm (PND 55-81 for males, PND 57-83 for females). Planned contrast testing showed that the male CSI group had greater anxiety-like behavior compared controls, but group differences were not apparent for CORT. CSI males had significantly higher levels of ethanol preference during drinking weeks 2-3 compared to all other groups and compared to SS and ISO groups in week 4. For the female cohort, we did not observe consistent group differences in anxiety-like behavior, CORT levels were unexpectedly lower in the ISO group only compared to the other groups, and group differences were not apparent for ethanol intake/preference. In conclusion, chronic stress during adolescence in the form of social instability increases anxiety-like behavior and ethanol preference in male rats, consistent with other models of

    We investigate whether maple syrup is a suitable sweetener in the management of type 2 diabetes using the Otsuka Long-Evans Tokushima Fatty (OLETF) rat. The enhancement in plasma glucose (PG) and glucose absorption in the small intestine were lower after the oral administration of maple syrup than after sucrose administration in OLETF rats, and no significant differences were observed in insulin levels. These data suggested that maple syrup might inhibit the absorption of glucose from the small intestine and preventing the enhancement of PG in OLETF rats. Therefore, maple syrup might help in the prevention of type 2 diabetes.

    Stress hormones such as cortisol are known to influence a wide range of cognitive functions, including hippocampal based spatial memory. In the brain, cortisol acts via two different receptors: the glucocorticoid (GR) and the mineralocorticoid receptor (MR). As the MR has a high density in the hippocampus, we examined the effects of pharmacological MR stimulation on spatial memory. Eighty healthy participants (40 women, 40 men, mean age=23.9years±SD=3.3) completed the virtual Morris Water Maze (vMWM) task to test spatial encoding and spatial memory retrieval after receiving 0.4mg fludrocortisone, a MR agonist, or placebo. There was no effect of MR stimulation on spatial encoding during the vMWM task. However, participants who received fludrocortisone exhibited improved spatial memory retrieval performance. There was neither a main effect of sex nor a sex-by-treatment interaction. In young healthy participants, MR stimulation improved hippocampal based spatial memory retrieval in a virtual Morris Water Maze task. Our study not only confirms the importance of MR function in spatial memory, but suggests beneficial effects of acute MR stimulation on spatial memory retrieval in humans.

  4. Comprehensive behavioural analysis of Long Evans and Sprague-Dawley rats reveals differential effects of housing conditions on tests relevant to neuropsychiatric disorders.

    Directory of Open Access Journals (Sweden)

    Karly M Turner

    Full Text Available Genetic (G and environmental (E manipulations are known to alter behavioural outcomes in rodents, however many animal models of neuropsychiatric disorders only use a restricted selection of strain and housing conditions. The aim of this study was to examine GxE interactions comparing two outbred rat strains, which were housed in either standard or enriched cages. The strains selected were the albino Sprague-Dawley rat, commonly used for animal models, and the other was the pigmented Long Evans rat, which is frequently used in cognitive studies. Rats were assessed using a comprehensive behavioural test battery and included well-established tests frequently employed to examine animal models of neuropsychiatric diseases, measuring aspects of anxiety, exploration, sensorimotor gating and cognition. Selective strain and housing effects were observed on a number of tests. These included increased locomotion and reduced pre-pulse inhibition in Long Evans rats compared to Sprague Dawley rats; and rats housed in enriched cages had reduced anxiety-like behaviour compared to standard housed rats. Long Evans rats required fewer sessions than Sprague Dawley rats to learn operant tasks, including a signal detection task and reversal learning. Furthermore, Long Evans rats housed in enriched cages acquired simple operant tasks faster than standard housed Long Evans rats. Cognitive phenotypes in animal models of neuropsychiatric disorders would benefit from using strain and housing conditions where there is greater potential for both enhancement and deficits in performance.

  5. We favor formal models of heuristics rather than lists of loose dichotomies: a reply to Evans and Over

    2009-01-01

    In their comment on Marewski et al. (good judgments do not require complex cognition, 2009) Evans and Over (heuristic thinking and human intelligence: a commentary on Marewski, Gaissmaier and Gigerenzer, 2009) conjectured that heuristics can often lead to biases and are not error free. This is a most surprising critique. The computational models of heuristics we have tested allow for quantitative predictions of how many errors a given heuristic will make, and we and others have measured the amount of error by analysis, computer simulation, and experiment. This is clear progress over simply giving heuristics labels, such as availability, that do not allow for quantitative comparisons of errors. Evans and Over argue that the reason people rely on heuristics is the accuracy-effort trade-off. However, the comparison between heuristics and more effortful strategies, such as multiple regression, has shown that there are many situations in which a heuristic is more accurate with less effort. Finally, we do not see how the fast and frugal heuristics program could benefit from a dual-process framework unless the dual-process framework is made more precise. Instead, the dual-process framework could benefit if its two “black boxes” (Type 1 and Type 2 processes) were substituted by computational models of both heuristics and other processes.

    2016-01-01

    Full Text Available Background: Enhanced colorectal sensitivity (i.e. visceral hypersensitivity is thought to be a pathophysiological mechanism in irritable bowel syndrome (IBS. In healthy men a circadian variation in rectal perception to colonic distention was described. Disturbed day and night rhythms, which occur in shift work and trans meridian flights, are associated with the prevalence of IBS. This raises the question whether disruptions of circadian control are responsible for the observed pathology in IBS. Prior to investigating altered rhythmicity in relation to visceral hypersensitivity in a rat model for IBS, it is relevant to establish whether normal rats display circadian variation similar to healthy men.  Methodology and findings: In rodents colorectal distension leads to reproducible contractions of abdominal musculature. We used quantification of this so called visceromotor response (VMR by electromyography (EMG to assess visceral sensitivity in rats. We assessed the VMR in normal male Long Evans rats at different time points of the light/dark cycle. Although a control experiment with male maternal separated rats confirmed that intentionally inflicted (i.e. stress induced changes in VMR can be detected, normal male Long Evans rats showed no variation in VMR along the light/dark cycle in response to colorectal distension. Conclusions: In the absence of a daily rhythm of colorectal sensitivity in normal control rats it is not possible to investigate possible aberrancies in our rat model for IBS.

    2004-01-01

    Study objective: To examine the involvement of Philip Morris in Living Tomorrow 2 and determine the rationale behind its involvement. Design: Research was conducted through a web based search of internal tobacco industry documents made publicly available through litigation. Main results: For approximately €1 000 000 Philip Morris (now Altria) became a co-initiator of Living Tomorrow 2, a tourist complex in Belgium that aims to demonstrate how we will be living in the future. In addition to promoting the company and its grocery products, Philip Morris is using the complex and its website to promote ventilation as a means of accommodating smokers and non-smokers in the indoor environment. Particular emphasis was placed on the bar and restaurant areas. Despite the rationale for its involvement, Philip Morris fails to acknowledge its role as a cigarette manufacturer. As a form of corporate sponsorship Philip Morris thought its involvement could evade any European tobacco advertising ban. Conclusions: Philip Morris is using a tourist attraction to promote its views on control of second hand smoke (SHS) and accommodation of smokers and non-smokers in the indoor environment. However, ventilation does not deal with the health effects of SHS. Policymakers must be cognisant of the devious tactics the industry employs to promote its own agenda, especially in relation to indoor air quality and smoking in public places. Tobacco control legislation should be continually modified and strengthened in response to the changing activities of the tobacco industry as it strives to evade existing legislation and deter the advent of new legislation.

    Recent research has revealed more evidence supporting the positive effects of music on humans and animals. However, evidence of music's effects on improving epilepsy in animals is sparse. This study aimed to clarify the influence of Mozart's music in Long Evans rats, which are characterized by spontaneous absence epilepsy (SAE) and high-voltage rhythmic spike (HVRS) discharges. Continuous electroencephalograms comprised of HVRS discharges, and behavioral performance were recorded in Long Evans rats (n=5) before, during, and after exposure to the Mozart's Sonata for Two Pianos in D Major, K.448 (Mozart K.448). The same evaluation was repeated after they had been subjected to daily exposure of the music for 20 days. Seizure frequencies and spontaneous HVRS discharges were reduced in all of the SAE rats during and after music exposure compared with the pre-music stage. The average seizure frequencies were 79.8±24.6, 48±15.2, and 33±12.1/h before, during, and after music exposure, respectively. The average run of spike episodes were 84.6±18.4, 52±17.8, and 36.8±16.9/h before, during, and after music exposure, respectively. The seizure frequencies and related run of spike episodes decreased by 39.8% and 38.5% during, and 58.6% and 56.6% post music exposure, respectively. The average run of spike durations and spike numbers also showed significant decreases (reduction by 47.1%, 47.8% during music and 60.8%, 61.3% post music). After daily music exposure for 20 days, the number of HVRS discharges and seizure frequencies during and after music exposure, however, showed no further accumulative reduction or adaptation effect. These results suggest that Mozart K.448 had a positive short-term effect in attenuating the spontaneous HVRS discharges in Long Evans rats. However, the mechanism needs further investigation.

  9. Hydrology, microbiology and carbon cycling at a high Arctic polythermal glacier, (John Evans Glacier, Ellesmere Island, Canada)

    Science.gov (United States)

    Skidmore, Mark Leslie

    Analysis of the hydrology, hydrochemistry and microbiology at polythermal John Evans Glacier and geochemical and isotopic data from Haut Glacier d'Arolla demonstrates that certain subglacial chemical weathering processes are microbially mediated. Subglacial drainage is likely an annual occurrence beneath John Evans Glacier and solute rich subglacial waters indicate over winter storage at the glacier bed. Subglacial microbial populations are also present, and are viable under simulated near in situ conditions at 0.3°C. This suggests that temperate subglacial environments at a polythermal glacier, which are isolated by cold ice above and around them, provide a viable habitat for life where basal water and organic carbon are present throughout the year. Thus, a subglacial microbial ecosystem based upon legacy carbon, (from old soils or surface inputs) rather than primary production may exist, where redox processes are a key component, and seasonal anoxia may occur. The existence of anoxic environments is supported by the presence of strictly anaerobic bacteria (sulphate reducing bacteria and methanogens) in the basal sediments---which are viable in culture at 4°C---and also argues that these bacteria are not washed in with oxygenated surface meltwaters, but are present in the subglacial environment. During the summer meltseason there is a large input of surficial waters to the subglacial system and water residence times are drastically reduced. Hence, kinetic weathering processes dominate, resulting in light delta 13C-DIC (dissolved inorganic carbon) in glacial runoff, as verified by experimental work on CaCO3 and John Evans Glacier sediments. The experiments demonstrate kinetic bedrock fractionation (KBF) during carbonate hydrolysis and that kinetic fractionation of CO2 (KFC) is proportional to the rate of CO2 draw down during the carbonation of carbonates. This results in significantly depleted delta13C-DIC values (≤-16 ‰) relative to the bedrock carbonate

    Full Text Available The Morris water maze represents the de-facto standard for testing hippocampal function in laboratory rodents. In the field of adult hippocampal neurogenesis, however, using this paradigm to assess the functional relevance of the new neurons yielded surprisingly inconsistent results. While some authors found aspects of water maze performance to be linked to adult neurogenesis, others obtained different results or could not demonstrate any effect of manipulating adult neurogenesis.In this review we discuss evidence that the large diversity of protocols and setups used is an important aspect in interpreting the differences in the results that have been obtained. Even simple parameters such as pool size, number and configuration of visual landmarks, or number of trials can become highly relevant for getting the new neurons involved at all. Sets of parameters are often chosen with implicit or explicit concepts in mind and these might lead to different views on the function of adult-generated neurons.We propose that the classical parameters usually used to measure spatial learning performance in the water maze might not be particularly well suited to sensitively and specifically detect the supposedly highly specific functional changes elicited by the experimental modulation of adult hippocampal neurogenesis. As adult neurogenesis is supposed to affect specific aspects of information processing only in the hippocampus, any claim for a functional relevance of the new neurons has to be based on hippocampus-specific parameters. We also placed a special emphasis on the fact that the DG facilitates the differentiation between contexts as opposed to just differentiating places.In conclusion, while the Morris water maze has proven to be one of the most effective testing paradigms to assess hippocampus-dependent spatial learning, new and more specific questions ask for new parameters. Therefore, the full potential of the water maze task remains to be tapped.

    1978-08-01

    Two sublines of commercially available Long-Evans hooded rats have been developed by genetic selection. These sublines have widely differing levels of erythrocyte 2,3-diphosphoglycerate (DPG) due to different alleles at a single genetic locus. In the present work, it is shown that rats from the commercial population are also polymorphic at a hemoglobin locus, probably involving two alleles of the IIIbeta-globin chain locus. Particular hemoglobin types have been found to be strongly associated with certain DPG types, not only in the high-DPG and low-DPG lines but also in the commercial population. Two explanations for this association are considered. One is a single-locus hypothesis, with hemoglobin allelic variation causing DPG variation, and the other is a two-locus hypothesis, with marked linkage disequilibrium.

  13. Evans blue dye-enhanced imaging of the brain microvessels using spectral focusing coherent anti-Stokes Raman scattering microscopy.

    Full Text Available We performed dye-enhanced imaging of mouse brain microvessels using spectral focusing coherent anti-Stokes Raman scattering (SF-CARS microscopy. The resonant signals from C-H stretching in forward CARS usually show high background intensity in tissues, which makes CARS imaging of microvessels difficult. In this study, epi-detection of back-scattered SF-CARS signals showed a negligible background, but the overall intensity of resonant CARS signals was too low to observe the network of brain microvessels. Therefore, Evans blue (EB dye was used as contrasting agent to enhance the back-scattered SF-CARS signals. Breakdown of brain microvessels by inducing hemorrhage in a mouse was clearly visualized using backward SF-CARS signals, following intravenous injection of EB. The improved visualization of brain microvessels with EB enhanced the sensitivity of SF-CARS, detecting not only the blood vessels themselves but their integrity as well in the brain vasculature.

    Objective: To observe the long-term efficacy of partial spleen embolization combined with vincristine infusion in treating refractory idiopathic thrombocytopenic purpura (ITP) and Evans syndrome. Methods: During the period of 2000-2007, partial spleen embolization together with vincristine infusion was carried out in 30 patients with refractory idiopathic thrombocytopenic purpura (n=24) or Evans syndrome (n=6). Vincristine infusion (2 mg) via splenic artery was performed before partial spleen embolization procedure. The long-term effectiveness was observed and analyzed. Results: One week after the treatment, the platelet count was increased from preoperative (10.23±8.28) × 10 9 /L to (140.28±85.45) × 10 9 /L in patients with ITP, while the platelet count was increased from preoperative (12±8) × 10 9 /L to (210±60) × 10 9 /L in patients with Evans syndrome. Meanwhile, the hemoglobin level showed an increase in different degrees, from preoperative (63.00±13.62) g/L to postoperative (123.00±13.14) g/L. The therapeutic effectiveness was 100%. During the follow-up time lasting for 3-5 years, recurrence was seen in 11 patients (36.7%) and the overall efficacy rate was 63.3%. Conclusion: For the treatment of refractory idiopathic thrombocytopenic purpura and Evans syndrome, partial spleen embolization combined with vincristine infusion carries reliable long-term efficacy.

    Purpose: For experimental studies investigating modalities and efficacy of transarterial chemoembolization (TACE) in hepatocellular carcinoma (HCC) an animal model resembling the human situation as closely as possible would be appropriate. Specifically, reproducible tumor growth characteristics with the capability for appropriate in vivo imaging to monitor treatment efficacy are required.Methods: Morris hepatoma 3924A was implanted into the liver of 30 ACI rats. Tumor growth was followed by angiography (n=10), ultrasound (US, n=30), native computed tomography (CT. n=16), and native magnetic resonance imaging (MRU n=30) between day 8 and day 36 after implantation. The radiological morphological characteristics were compared with the macroscopic and microscopic histological findings of the explanted tumors.Results: In all 30 animals a solitary liver tumor was found and macroscopically no signs of metastases, ascites, or peritoneal tumor were visible. On histopathological examination tumor sizes ranged between 27 ± 3 mm 3 (day 8) and 3468 ± 79 mm 3 (day 36). The first signs of tumor necrosis occurred at day 16. US allowed tumor visualization from day 8, MRI from day 8, angiography from day 10, and CT from day 14.Conclusions: The tumor model has the potential to be used for the visualization of tumor growth by MRI and US. The potential for monitoring therapeutic effects of TACE needs to be investigated.

    The description of the installation with inverted light is given as well as its software EthoStudio, which allows tracking the movements of any color animal in the water Morris maze (WMM) in high definition. The installation is based on the transmitted light technology (inverted light). The software gives possibility to estimate a wide range of learning indices. We have studied the statistic properties of three most widespread indices: latent time of platform finding, covered distance and the sum of distances to the center of the platform. The covered distance has shown the best statistic characteristics if compared to two other indices. The influence of polymorphism C1473G in the gene of the key serotonin synthesis enzyme, tryptophan hydroxylase 2, on the learning abilities of mice in WMM has been studied. Mice of the unique congenic lines B6-1473C and B6-12473G that differ by the polymorphic alleles C1473G have not demonstrated the association between the ability to learn and the genetically determined activity of tryptophan hydroxylase 2 in the brain.

    Aim of the study Curcuma comosa extract and some purified compounds from this plant have been reported to have estrogenic-like effects, and estrogen improves learning in some animals and potentially in postmenopausal women; therefore, this study tested the hypothesis that Curcuma comosa and estrogen have similar beneficial effects on spatial learning and memory. Materials and methods Curcuma comosa hexane extract, containing 0.165 mg of (4E,6E)-1,7-diphenylhepta-4,6-dien-3-one per mg of the crude extract, was orally administered to ovariectomized Wistar rats at the doses of 250 or 500 mg/kg body weight. 17β-estradiol (10 μg/kg body weight, subcutaneously) was used as a positive control. Thirty days after the initiation of treatment, animals were tested in a Morris water maze for spatial learning and memory. They were re-tested every 30 days and a final probe trial was run on day 119. Results Compared to control rats, OVX rats displayed significant memory impairment for locating the platform in the water maze from day 67 after the surgery, onward. In contrast, OVX rats treated with either Curcuma comosa or estrogen were significantly protected from this decline in cognitive function. Further, the protection of cognitive effects by Curcuma comosa was larger at higher dose. Conclusions These results suggest that long-term treatment with Curcuma comosa has beneficial effects on learning and memory function in rats. PMID:20420894

    Recent studies have provided evidence that nitric oxide (NO) has a role in certain forms of memory formation. Spatial learning is one of the cognitive abilities that has been found to be impaired after systemic administration of an NO-synthase inhibitor. As the hippocampus has a pivotal role in spatial orientation, the present study examined the role of hippocampal NO in spatial learning and reversal learning in a Morris task in adult rats. It was found that N omega-nitro-L-arginine infusions into the dorsal hippocampus affected the manner in which the rats were searching the submerged platform during training, but did not affect the efficiency to find the spatial location of the escape platform. Hippocampal NO-synthase inhibition did not affect the learning of a new platform position in the same water tank (i.e. reversal learning). Moreover, no treatment effects were observed in the probe trials (i.e. after acquisition and after reversal learning), indicating that the rats treated with N omega-nitro-L-arginine had learned the spatial location of the platform. These findings were obtained under conditions where the NO synthesis in the dorsal hippocampus was completely inhibited. On the basis of the present data it was concluded that hippocampal NO is not critically involved in place learning in rats.

    To analyse the models Philip Morris (PM) and British American Tobacco (BAT) used internally to understand tobacco control non-governmental organizations (NGOs) and their relationship to the global tobacco control policy-making process that resulted in the Framework Convention for Tobacco Control (FCTC). Analysis of internal tobacco industry documents in the Legacy Tobacco Document Library. PM contracted with Mongoven, Biscoe, and Duchin, Inc. (MBD, a consulting firm specialising in NGO surveillance) as advisors. MBD argued that because NGOs are increasingly linked to epistemic communities, NGOs could insert themselves into the global policy-making process and influence the discourse surrounding the treaty-making process. MBD advised PM to insert itself into the policy-making process, mimicking NGO behaviour. BAT's Consumer and Regulatory Affairs (CORA) department argued that global regulation emerged from the perception (by NGOs and governments) that the industry could not regulate itself, leading to BAT advocating social alignment and self-regulation to minimise the impact of the FCTC. Most efforts to block or redirect the FCTC failed. PM and BAT articulated a global policy-making environment in which NGOs are key, non-state stakeholders, and as a result, internationalised some of their previous national-level strategies. After both companies failed to prevent the FCTC, their strategies began to align. Multinational corporations have continued to successfully employ some of the strategies outlined in this paper at the local and national level while being formally excluded from ongoing FCTC negotiations at the global level.

    used in South Africa to facilitate clinical decision-making or document treatment outcomes for patients with low back pain (LBP. This study investigated the internal consistency and clinical utility of a back-specific functional status measure, the Roland Morris Disability Questionnaire (RMDQ, and determined its ability to confirm the need for spinal fusion surgery. Method: Aretrospective, descriptive design was used with 42 patients with chronic mechanical low back pain who consulted a private Orthopaedic surgeon in Cape Town over a one year  period. All patients completed the RMDQ prior to their consultation. On completion of the medical examination, a rating for surgery was determined for each patient. The completed questionnaires were analysed using Statistical Package for the Social Sciences (SPSS. Results: The mean RMDQ score was 8.6 (N=42; median=9.0; range=2-21. Cronbach’s alpha showed a high internal consistency between items (.92. A categorical principal component analysis (CATPCA identified two distinct dimensions in the RMDQ. Item reduction improved the internal consistency and thus the construct validity of the RMDQ. There was a low correlation between the surgeon’s rating for surgery and RMDQ scores (r=.40; P<.01. Conclusion: The RMDQ shows some good psychometric properties but some adjustments could improve it. The RMDQ cannot be used to predict the need for spinal fusion surgery.

  6. Corporate Image and Public Health: An Analysis of the Philip Morris, Kraft, and Nestlé Websites

    Companies need to maintain a good reputation to do business; however, companies in the infant formula, tobacco, and processed food industries have been identified as promoting disease. Such companies use their websites as a means of promulgating a positive public image, thereby potentially reducing the effectiveness of public health campaigns against the problems they perpetuate. The author examined documents from the websites of Philip Morris, Kraft, and Nestlé for issue framing and analyzed them using Benoit’s typology of corporate image repair strategies. All three companies defined the problems they were addressing strategically, minimizing their own responsibility and the consequences of their actions. They proposed solutions that were actions to be taken by others. They also associated themselves with public health organizations. Health advocates should recognize industry attempts to use relationships with health organizations as strategic image repair and reject industry efforts to position themselves as stakeholders in public health problems. Denormalizing industries that are disease vectors, not just their products, may be critical in realizing positive change. PMID:22420639

    Evans syndrome (ES) is a rare disease characterized by simultaneous or sequential development of autoimmune hemolytic anemia (AIHA) and immune thrombocytopenia (ITP) with or without immune neutropenia. Splenectomy is one of the treatment options for disease refractory to medical therapy. Venous thromboembolism (VTE) following splenectomy for hematological diseases has an incidence of 10%. Here we describe a case report of a young patient hospitalized with severe hemolytic anemia with Hgb 4.8 g/dl. He developed thrombocytopenia with platelet nadir of 52,000/mm 3 , thus formally diagnosed with ES. He failed standard medical therapy. He underwent splenectomy and had a fatal outcome. Autopsy confirmed the cause of death as pulmonary embolism (PE). This case report and review of the literature highlight important aspects of the association between VTE, splenectomy, and hemolytic syndromes including the presence of thrombocytopenia. The burden of the disease is reviewed as well as various pathophysiologic mechanisms contributing to thromboembolic events in these patients and current perioperative prophylactic anticoagulation strategies. Despite an advancing body of literature increasing awareness of VTE following splenectomy, morbidity and mortality remains high. Identifying high risk individuals for thromboembolic complications from splenectomy remains a challenge. There are no consensus guidelines for proper perioperative and post-operative anti-coagulation. We encourage future research to determine which factors might be playing a role in increasing the risk for VTE in real time with hope of forming a consensus to guide management.

    Bis(melaminium) sulphate dihydrate (BMSD), an interesting melaminium derivative for nonlinear optical activity, has been subjected to vibrational spectral analysis using FT IR and FT Raman spectra. The analysis has been aided by the Potential Energy Distribution (PED) of vibrational spectral bands, derived using density functional theory (DFT) at B3LYP/6-31G(d) level. The geometry is found to correlate well with the XRD structure and the band profiles for certain vibrations in the finger print region have been theoretically explained using Evans hole. The detailed Natural Bond Orbital (NBO) analysis of the hydrogen bonding in BMSD has also been carried out to understand the correlation between the stabilization energy of hyperconjugation of the lone pair of donor with the σ(∗) orbital of hydrogen-acceptor bond and the strength of hydrogen bond. The theoretical calculation shows that BMSD has NLO efficiency, 2.66 times that of urea. The frontier molecular orbital analysis points to a charge transfer, which contributes to NLO activity, through N-H…O intermolecular hydrogen bonding between the melaminium ring and the sulphate. The molecular electrostatic potential (MEP) mapping has also been performed for the detailed analysis of the mutual interactions between melaminium ring and sulphate ion.

    1997-06-01

    The Morris water maze is commonly used to test cognitive function in rodent models of neurological disorders including age-related cognitive deficits. It is often assumed that the most profoundly impaired aged rats may be blind due to retinal degeneration, and it has been reported that animals with visual sensory deficits can be identified based on their performance in a cued platform task. The results of the present study demonstrate that blind rats can perform surprisingly well in the reference memory version of the Morris water maze, and that blind rats cannot be selectively excluded based on performance in the cued platform task since atropine-treated rats also perform poorly in the cued platform task. Future studies may be able to develop screening procedures that help to eliminate subjects with non-cognitive deficits, but the present results do not support the use of the cued platform or straight swim task as screening procedures. Experimenters must be careful to consider the role that visual sensory function and other non-cognitive factors may have in performance of the spatial learning Morris water maze, and also the role that severe cognitive deficits may have in performance of the cued platform task.

    A translation, cross-cultural adaptation, and psychometric analysis. The aim of this study was to translate, cross-culturally adapt, and validate the Yoruba version of the RMDQ. The Roland-Morris Disability Questionnaire (RMDQ) is a valid outcome tool for low back pain (LBP) in clinical and research settings. There seems to be no valid and reliable version of the RMDQ in the Nigerian languages. Following the Guillemin criteria, the English version of the RMDQ was forward and back translated. Two Yoruba translated versions of the RMDQ were assessed for clarity, common language usage, and conceptual equivalence. Consequently, a harmonized Yoruba version was produced and was pilot-tested among 20 patients with nonspecific long-term LBP (NSLBP) for cognitive debriefing. The final version of the Yoruba RMDQ was tested for its construct validity and re-retest reliability among 120 and 87 patients with NSLBP, respectively. Pearson product moment correlation coefficient (r) of 0.82 was obtained for reliability of the Yoruba version of the RMDQ. The test-retest reliability of the Yoruba RMDQ yielded Cronbach alpha 0.932, while the intraclass correlation (ICC) ranged between 0.896 and 0.956. The analysis of the global scores of both the English and Yoruba versions of the RMDQ yielded ICC value of between 0.995 (95% confidence interval 0.996-0.997), with the item-by-item Kappa agreement ranging between 0.824 and 1.000. The external validity of RMDQ using Quadruple Visual Analogue Scale was r = -0.596 (P = 0.001). The Yoruba version of the RMDQ had no floor/ceiling effects, as no patient achieved either of the maximum or the minimum possible scores. The Yoruba version of the RMDQ has excellent reliability and validity and may be an appropriate outcome tool for clinical and research purposes among Yoruba-speaking patients with LBP. 3.

    To assess the cross cultural-adaptations of the Roland Morris Disability Questionnaire (RMDQ). English and Chinese databases were searched through December 2017. Cross-cultural adaptation and measurement properties were evaluated using the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures and the Quality Criteria for Psychometric Properties of Health Status Questionnaire. Among 34 studies, there were 31 RMDQ adaptations for 26 different languages/cultures. In the cross-cultural adaptation process, few studies reported expert committees completely constituted (3/31), and only ten studies complete the test of the pre-final version (10/31) due to insufficient sample sizes. As for the measurement properties, content validity (31/31) and construct validity (24/31) were assessed in most of the adaptations, whereas internal consistency (0/31), agreement (5/31), responsiveness (3/31), interpretability (6/31), and floor and ceiling effects (6/31) were not. The Hungarian and Moon's Korean adaptations were the highest quality translations. Where there were multiple adaptations for a language/culture, the Moon's Korean and Fan's simplified Chinese-Chinese Mainland adaptations are recommended over the other Korean or simplified Chinese-Chinese Mainland adaptations. Further studies are required to fully assess the measurement properties of the Arabic-Moroccan, Arabic-Tunisian, German- Austrian, Greek, Guajarati, Kim's Korean, Persian-Iranian, Polish, He's simplified Chinese-Chinese Mainland, Spanish, Spanish-Chilean, Thai, traditional Chinese-Taiwan, and Turkish adaptations of the RMDQ.

    The forefoot abduction component of the flexible adult-acquired flatfoot can be addressed with lengthening of the anterior process of the calcaneus. We hypothesized that the step-cut lengthening calcaneal osteotomy (SLCO) would decrease the incidence of nonunion, lead to improvement in clinical outcome scores, and have a faster time to healing compared with the traditional Evans osteotomy. We retrospectively reviewed 111 patients (143 total feet: 65 Evans, 78 SLCO) undergoing stage IIB reconstruction followed clinically for at least 2 years. Preoperative and postoperative radiographs were analyzed for the amount of deformity correction. Computed tomography (CT) was used to analyze osteotomy healing. The Foot and Ankle Outcome Scores (FAOS) and lateral pain surveys were used to assess clinical outcomes. Mann-Whitney U tests were used to assess nonnormally distributed data while χ 2 and Fisher exact tests were used to analyze categorical variables (α = 0.05 significant). The Evans group used a larger graft size ( P lengthening. Level III, retrospective cohort study.

    Previously secret internal tobacco company documents show that the tobacco industry launched an extensive multifaceted effort to influence the scientific debate about the harmful effects of secondhand smoke. Integral to the industry's campaign was an effort to derail the Environmental Protection Agency's (EPA) risk assessment on environmental tobacco smoke (ETS) by recruiting a network of journalists to generate news articles supporting the industry's position and pushing its public relations messages regarding the ETS issue. Searches of previously secret internal tobacco industry records were conducted online and at the Minnesota Tobacco Document Depository. In addition, searches on the World Wide Web were conducted for each National Journalism Center alumnus. Lexis-Nexis was used to locate news stories written by the journalists cited in this paper. Philip Morris turned to its public relations firm Burson Marsteller to "build considerable reasonable doubt em leader particularly among consumers" about the "scientific weaknesses" of the EPA report. A Washington, DC, media and political consultant Richard Hines was a key player in carrying out Burson Marsteller's media recommendations of "EPA bashing" for Philip Morris. In March 1993, Philip Morris' vice president of corporate affairs policy and administration reported to Steve Parrish, vice president and general counsel of Philip Morris, that their consultant was "responsible for a number of articles that have appeared in em leader major news publications regarding EPA and ETS." In addition to placing favorable stories in the press through its consultant, Philip Morris sought to expand its journalist network by financially supporting a U.S. school of journalism; the National Journalism Center (NJC). Philip Morris gleaned "about 15 years worth of journalists at print and visual media throughout the country em leader to get across [its] side of the story" resulting in "numerous pieces consistent with our point of

  17. Behavioral Phenotyping of Juvenile Long-Evans and Sprague-Dawley Rats: Implications for Preclinical Models of Autism Spectrum Disorders.

    Full Text Available The laboratory rat is emerging as an attractive preclinical animal model of autism spectrum disorder (ASD, allowing investigators to explore genetic, environmental and pharmacological manipulations in a species exhibiting complex, reciprocal social behavior. The present study was carried out to compare two commonly used strains of laboratory rats, Sprague-Dawley (SD and Long-Evans (LE, between the ages of postnatal day (PND 26-56 using high-throughput behavioral phenotyping tools commonly used in mouse models of ASD that we have adapted for use in rats. We detected few differences between young SD and LE strains on standard assays of exploration, sensorimotor gating, anxiety, repetitive behaviors, and learning. Both SD and LE strains also demonstrated sociability in the 3-chamber social approach test as indexed by spending more time in the social chamber with a constrained age/strain/sex matched novel partner than in an identical chamber without a partner. Pronounced differences between the two strains were, however, detected when the rats were allowed to freely interact with a novel partner in the social dyad paradigm. The SD rats in this particular testing paradigm engaged in play more frequently and for longer durations than the LE rats at both juvenile and young adult developmental time points. Results from this study that are particularly relevant for developing preclinical ASD models in rats are threefold: (i commonly utilized strains exhibit unique patterns of social interactions, including strain-specific play behaviors, (ii the testing environment may profoundly influence the expression of strain-specific social behavior and (iii simple, automated measures of sociability may not capture the complexities of rat social interactions.

  18. Identification of a Major Locus Contributing to Erythrocyte 2,3-Diphosphoglycerate Variability in Hooded (Long-Evans) Rats

    The erythrocyte glycolytic intermediate 2,3-diphosphoglycerate (DPG) and adenosine triphosphate (ATP) play an important role in oxygen transport and delivery by binding to hemoglobin (Hb) and reducing its affinity for oxygen. Considerable quantitative variability in the levels of DPG and ATP exists in human populations and in a population of hooded (Long-Evans) rats we have studied. This paper presents the results of studies on the genetic component of DPG-level variation in an outbred population of hooded rats. Beginning with about 100 rats, a two-way selection experiment was initiated. Pairs of rats with the highest DPG levels were mated to produce a High-DPG rat strain and animals with the lowest DPG levels were mated to produce a Low-DPG strain. Mean DPG levels responded rapidly to selection and, from generation 3 on, the differences between strain means were highly significant. Ten High-DPG strain rats were intercrossed with 10 Low-DPG strain rats of generation 10 to produce an F1 generation in which the DPG levels were almost as high as those of High-DPG animals. This indicates partial dominance of High-DPG alleles. The F2 DPG-level distribution showed two distinct subpopulations. The high DPG subpopulation contained three times as many animals as the low DPG subpopulation. From these results and the statistical analyses performed, it was concluded that the DPG differences between strains were due to an allelic difference at one major locus, the allele carried by the High-DPG strain showing partial dominance over the allele carried by the Low-DPG strain. It appears that this locus may also effect ATP levels to a large extent and is polymorphic in hooded rat populations. Identification of this locus gives us a useful tool for studies of the physiological effects of DPG variability, as well as providing an example of a major gene effect in a quantitatively varying trait.

    Studies showed that early postnatal exposure to the herbicide atrazine (ATR) delayed preputial separation (PPS) and increased incidence of prostate inflammation in adult Wistar rats. A cross-fostering paradigm was used in this study to determine if gestational exposure to ATR would also result in altered puberty and reproductive tissue effects in the male rat. Timed-pregnant Long-Evans (LE) rats were dosed by gavage on gestational days (GD) 15-19 with 100 mg ATR/kg body weight (BW) or 1% methylcellulose (controls, C). On postnatal day (PND)1, half litters were cross-fostered, creating 4 treatment groups; C-C, ATR-C, C-ATR, and ATR-ATR (transplacental-milk as source, respectively). On PND4, male offspring in the ATR-ATR group weighed significantly less than the C-C males. ATR-ATR male pups had significantly delayed preputial separation (PPS). BWs at PPS for C-ATR and ATR-ATR males were reduced by 6% and 9%, respectively, from that of C-C. On PND120, lateral prostate weights of males in the ATR-ATR group were significantly increased over C-C. Histological examination of lateral and ventral prostates identified an increased distribution of inflammation in the lateral prostates of C-ATR males. By PND220, lateral prostate weights were significantly increased for ATR-C and ATR-ATR, but there were no significant changes in inflammation in either the lateral or ventral prostate. These results suggest that in LE rats, gestational ATR exposure delays PPS when male offspring suckle an ATR dam, but leads to increased lateral prostate weight via transplacental exposure alone. Inflammation present at PND120 does not increase in severity with time

    The current experiment examined the effects of 10 days of chronic intermittent ethanol (CIE) exposure on anxiety-like behavior and home cage ethanol intake using a 20% intermittent access (M, W, F) paradigm in male and female Long-Evans rats. Withdrawal from alcohol dependence contributes to relapse in humans and increases in anxiety-like behavior and voluntary ethanol consumption in preclinical models. Our laboratory has shown that 10 days of CIE exposure produces both behavioral and neurophysiological alterations associated with withdrawal in male rats; however, we have yet to examine the effects of this exposure regime on ethanol intake in females. During baseline, females consumed more ethanol than males but, unlike males, did not show escalations in intake. Rats were then exposed to CIE and were again given intermittent access to 20% ethanol. CIE males increased their intake compared to baseline, whereas air-exposed males did not. Ethanol intake in females was unaffected by CIE exposure. Notably, both sexes expressed significantly elevated withdrawal-associated anxiety-like behavior in the plus maze. Finally, rats were injected with the cannabinoid CB1 receptor antagonist, SR141716A (0, 1, 3, 10mg/kg, i.p.) which reduced ethanol intake in both sexes. However, females appear to be more sensitive to lower doses of this CB1 receptor antagonist. Our results show that females consume more ethanol than males; however, they did not escalate their intake using the intermittent access paradigm. Unlike males, CIE exposure had no effect on drinking in females. It is possible that females may be less sensitive than males to ethanol-induced increases in drinking after a short CIE exposure. Lastly, our results demonstrate that males and females may have different pharmacological sensitivities to CB1 receptor blockade on ethanol intake, at least under the current conditions.

    Three different geophysical sensor types were used to characterize the underwater pressure waves and ground velocities generated by the underwater firing of seismic water guns. These studies evaluated the use of water guns as a tool to alter the movement of Asian carp. Asian carp are aquatic invasive species that threaten to move into the Great Lakes Basin from the Mississippi River Basin. Previous studies have identified a threshold of approximately 5 pounds per square inch (lb/in2) for behavioral modification and for structural limitation of a water gun barrier.Two studies were completed during August 2014 and May 2015 in a backwater pond connected to the Illinois River at a sand and gravel quarry near Morris, Illinois. The August 2014 study evaluated the performance of two 80-cubic-inch (in3) water guns. Data from the 80-in3 water guns showed that the pressure field had the highest pressures and greatest extent of the 5-lb/in2 target value at a depth of 5 feet (ft). The maximum recorded pressure was 13.7 lb/in2, approximately 25 ft from the guns. The produced pressure field took the shape of a north-south-oriented elongated sphere with the 5-lb/in2 target value extending across the entire study area at a depth of 5 ft. Ground velocities were consistent over time, at 0.0067 inches per second (in/s) in the transverse direction, 0.031 in/s in the longitudinal direction, and 0.013 in/s in the vertical direction.The May 2015 study evaluated the performance of one and two 100-in3 water guns. Data from the 100-in3 water guns, fired both individually and simultaneously, showed that the pressure field had the highest pressures and greatest extent of the 5-lb/in2 target value at a depth of 5 ft. The maximum pressure was 57.4 lb/in2, recorded at the underwater blast sensor closest to the water guns (at a horizontal distance of approximately 3 ft), as two guns fired simultaneously. Pressures and extent of the 5-lb/in2 target value decrease above and below this 5-ft depth

  3. Housing the Citizen-Consumer in Post-war Britain: The Parker Morris Report, Affluence and the Even Briefer Life of Social Democracy.

    Kefford, Alistair

    2018-06-01

    This article examines debates about the design and provision of post-war housing within the papers and report of the Parker Morris committee. It does so to show how the models of citizens' rights and expectations which underpinned post-war welfare provision were transformed by mass affluence and the dynamic sphere of commercial consumption. Parker Morris's deliberations demonstrate that, as early as the 1950s, the citizen-subject was reimagined as a consuming individual, with requirements based on their expressive needs and consuming desires, and that this had far-reaching consequences for social democratic systems of universal welfare provision. The introduction of consumerist imperatives into publicly defined models of citizens' needs enhanced the political and cultural authority of the commercial domain, prompted a heightened role for commercial experts and market logics within public governance, and served to devalue socialized forms of provision in favour of consumer choice in the private market. The article thus engages with the growing scholarship on the politics of mass consumerism by showing how the material and emotional comforts of post-war affluence came to be constructed as critical to social democratic citizenship and selfhood. Situating this uneasy entanglement of social democratic rights with consumer satisfaction as part of a wider trajectory of political change, the piece suggests that Parker Morris marks an early but significant moment in the transition from post-war welfarism and social democracy to the consumer- and market-oriented forms of governance which came to dominate British politics and society in the latter part of the twentieth century.

    The herpes simplex virus type 1 thymidine kinase gene(HSV1-tk) is an attractive candidate as a reporter gene in noninvasive reporter gene monitoring system. The HSV1-tk gene was chosen as a reporter gene, because it has been extensively studied, and there are appropriate reporter probes, substrates of HSV1-tk gene product, to apply for HSV1-tk gene imaging. We used radiolabeled 5-iodovinyl-2'-deoxyuridine (IVDU) and 5-lodovinyl-2'-fluoro-2'-deoxyuridine (IVFRU) as reporter probes for HSV1-tk gene monitoring system. We prepared HSV1-tk gene transduced Morris hepatoma cell line using retroviral vector, MOLTEN containing HSV1-tk gene. And we confirmed the HSV1-tk gene expression by Northern blotting and Western blotting. We compared in vitro uptakes of radioiodinated IVDU and IVFRU to monitor HSV1-tk gene expression in Morris hepatoma cell line (MCA) and HSV1-tk gene tranduced MCA (MAC-tk) cells until 480 minutes. We also performed correlation analysis between percentage of HSV1-tk gene tranduced MCA cell % (MCA-tk%) and uptakes of radiolabeled IVDU or IVFRU. MCA-tk cell expressed HSV1-tk mRNA and HSV1-TK protein. Two compounds showed minimal uptake in MCA, but increased uptake was observed in MCA-tk. IVDU showed 4-fold higher accumulation than IVFRU at 480 min in MCA-tk (p<0.01). Both IVDU and IVFRU uptake were linearly correlated (R{sup 2}>0.96) with increasing MCA-tk%. The rediolabeld IVDU and IVFRU showed higher specific accumulation in retrovirally HSV1-tk gene transfected Morris hepatoma cell line. Both IVDU and IVFRU could be used as good substrates for evaluation of HSV1-tk gene expression.

    Protein crystallography represents at present the most productive and most widely used method to obtain structural information on target proteins and protein-ligand complexes within the atomic resolution range. The knowledge obtained in this way is essential for understanding the biology, chemistry, and biochemistry of proteins and their functions but also for the development of compounds of high pharmacological and medicinal interest. Here, we address the very central problem in protein crystallography: the unpredictability of the crystallization process. Obtaining protein crystals that diffract to high resolutions represents the essential step to perform any structural study by X-ray crystallography; however, this method still depends basically on trial and error making it a very time- and resource-consuming process. The use of additives is an established process to enable or improve the crystallization of proteins in order to obtain high quality crystals. Therefore, a more universal additive addressing a wider range of proteins is desirable as it would represent a huge advance in protein crystallography and at the same time drastically impact multiple research fields. This in turn could add an overall benefit for the entire society as it profits from the faster development of novel or improved drugs and from a deeper understanding of biological, biochemical, and pharmacological phenomena. With this aim in view, we have tested several compounds belonging to the emerging class of polyoxometalates (POMs) for their suitability as crystallization additives and revealed that the tellurium-centered Anderson-Evans polyoxotungstate [TeW 6 O 24 ] 6- (TEW) was the most suitable POM-archetype. After its first successful application as a crystallization additive, we repeatedly reported on TEW's positive effects on the crystallization behavior of proteins with a particular focus on the protein-TEW interactions. As electrostatic interactions are the main force for TEW binding

    To assess the possibility that acute caffeine's behavioral action might depend on rats' strain, effects of 50mg/kg of the drug were observed on activity, anxiety-related behavior and habituation learning in male and female rats from three different strains, namely PVG/c, Long-Evans and Wistar. All subjects were tested in an open field, an elevated plus maze and a light-dark box. For the three strains combined, increased occupancy of the center of the open field and entries of the open plus-maze arms with caffeine suggested caffeine-induced anxiolysis, whereas increased grooming in the open field, decreased rearing in the plus maze and increased risk assessment in the light-dark box were consistent with anxiogenesis. Caffeine also reduced open-field rearing only for PVG/c rats, and entries into and occupation of the light side of the light-dark box only for Long-Evans rats, and increased total defecation in the three types of apparatus for all three strains combined. Overall, caffeine appeared to be mainly anxiogenic. The drug also increased open-field ambulation for PVG/c rats and walking for all rats, but decreased open-field ambulation and entries into the plus maze closed arms for Wistar rats alone. In general, Wistar rats appeared to be the least and Long-Evans the most anxious of the three strains investigated. Caffeine also decreased within-session habituation of open-field ambulation for PVG/c rats alone, thereby suggesting strain-dependent interference with non-associative learning and short-term memory. Several overall sex differences were also observed that supported female rats being more active and less anxious than males. Copyright © 2015 Elsevier Inc. All rights reserved.

    The goal of the UMM STEP program is to increase the number of graduates in STEM fields through innovative curricular, recruiting and mentoring strategies. A unique focus of the UMM STEP program is increasing the number of Native American science majors. The STEP program fosters a summer research environment where peer interaction and mentoring creates a web of support. To do so we will establish a supportive and fulfilling pipeline that: 1) Identifies Native American students and involves them in research while they are high school; 2) Mentors and prepares participants for university academics the summer before their freshman year; 3) Provides a complete tuition waiver, mentoring and a support network throughout their undergraduate career; and 4) Involves participants in an active and dynamic summer undergraduate research environment where under-represented individuals are in the majority. The third and fourth components of this pipeline are in very good shape. The Morris campus was originally established as an Indian School in 1887. When the federal government deeded the Indian school campus to the University of Minnesota a stipulation was that Native American students attend the college for free. At present, 196 Native Americans are enrolled at UMM (50 are STEM majors). The UMM STEP research experience provides the unique opportunity to interact with a scientific community that both breaks down a number of traditional barriers and aids in the maturation of these students as scientists. In Summer 2008, 4 students were involved in summer research and in 2009 seven Native American students participated. Early efforts of the UMM STEP program are encouraging. UMM Admissions staff used the UMM STEP program to recruit Native American students and the P.I. phoned “uncommitted admits”, visited reservations and hosted reservation student visits. The result was an increase in freshman Native American Science majors from 7 in Fall 2007, 15 in fall 2008 and 20 in fall

    60-80% of the population experience chronic low back pain at some point in their lives [1], with women suffering more frequently [2]. Low back pain-related ailments lead to long-term or recurrent disability [3, 4]. Rehabilitation based on physiotherapy provides a viable alternative and is rightly regarded as safer for patients. However, finding an effective method of rehabilitation is a difficult task [5, 6]. The aim of this study was to compare the outcomes of rehabilitation in women with chronic low back pain using the Oswestry and Roland-Morris Disability Scales and to identify factors influencing the degree of functional disability in patients with chronic low back pain. The study involved 319 women aged 18-75 years (mean age = 45 years, SD ± 16. 3). The participants were undergoing treatment at the Rehabilitation Centre of Zamość University of Management and Administration on account of chronic low back pain, following two or more episodes lasting longer than three months. The outcomes of rehabilitation were assessed with ODI and RMDQ. We obtained comparable results with the ODI and RMDQ and found statistically significant improvement in functional status after rehabilitation (ODI: p disability and age (ODI: p disability vs. place of residence (ODI: p disability, as demonstrated both by the Oswestry Disability Index and the Roland-Morris Disability Questionnaire. 2. The relationship between the degree of functional disability and age, BMI, WHR, and hypertension was also confirmed by both questionnaires.

    This study adopted the forced-swimming paradigm to induce depressive symptoms in rats and evaluated the effects on learning and memory processing. Furthermore, the effects of the water extract of Gastrodia elata Bl., a well-known Chinese traditional medicine, on amnesia in rats subjected to the forced-swimming procedure were studied. Rats were subjected to the forced-swimming procedure, and the inhibitory avoidance task and Morris water maze were used to assess learning and memory performance. The acquisition of the two tasks was mostly impaired after the 15-minute forced-swimming procedure. Administration of the water extract of G. elata Bl. for 21 consecutive days at a dosage of 0.5 or 1.0 g/kg of body weight significantly improved retention in the inhibitory avoidance test, and the lower dose showed a better effect than the higher one and the antidepressant fluoxetine (18 mg/kg of body weight). In the Morris water maze, the lower dose of the water extract of G. elata Bl. significantly improved retention by shortening escape latency in the first test session and increasing the time in searching the target zone during the probe test. These findings suggest that water extracts of G. elata Bl. ameliorate the learning and memory deficits induced by forced swimming.

    Chronic decreases in brain cholinergic functions due to intraventricular administration of the neurotoxin AF64A were accompanied by increases in the latent period of locating an invisible platform during training of rats in a Morris water test, as compared with control sham-operated animals. Recordings of the animals' movement trajectories using a video camera along with an original computer program (Behavioral Vision) showed that administration of 17beta-estradiol and its synthetic analog J-861 (0.2 mg/kg p.o. daily for seven days before and 10 days after single intraventricular injections of AF64A) improved learning. The directivity of platform search trajectories was assessed quantitatively using a new parameter--trajectory straightness. Introduction of the "passive swimming" parameter allowed periods of immobility in water to be identified within the total latent period in animals after administration of AF64A; 17beta-estradiol but not J-861 "eliminated" these periods. The new parameters (especially trajectory straightness) allowed the ability to learn to be discriminated from decreases in mobility, including mobility losses due to study agents, in the Morris water test.

    Diabetic keratopathy is a well-known ocular complication secondary to type 2 diabetes mellitus. In this study, we performed a kinetic analysis of corneal wound healing in Long-Evans rats (normal rat) and Otsuka Long-Evans Tokushima Fatty (OLETF) rats, a model of type 2 diabetes mellitus. Corneal wound healing in 7-week-old normal rats was mostly complete 24 h after corneal epithelial abrasion, and the process of corneal wound healing took place according to an equation with a first-order rate constant. The rate of corneal wound healing in normal rats decreased with aging. The process of corneal wound healing in 38- and 60-week-old normal and OLETF rats occurred in two phases with rate constants for the first and second phases represented as alpha and beta, respectively. The alpha and beta values in 38- and 60-week-old OLETF rats were lower than those in normal rats of the corresponding age. Furthermore, a close relationship was observed between the corneal wound healing rate constant and plasma glucose levels in OLETF rats. The present studies suggest the sequence of events that occur following damage to the corneal surface in OLETF rats as a model animal for a human type 2 diabetes mellitus.

    3, 4-methylenedioxymethamphetamine (MDMA; also known as 'ecstasy') has been shown to impair learning and spatial memory in adult and neonatal rats.Many studies have focused on the acute effects of MDMA on memory.In the present study, we intraperitoneally administered MDMA (0, 5, 10, 20 mg/kg) to adult male rats to investigate the effects of different doses on rat spatial memory in the Morris water maze, body temperature, and mortality, twice a day, for 7 successive days.The results indicated that MDMA impaired spatial memory dose-dependently, with the highest dose (20 mg/kg) exerting the strongest effects.In addition, MDMA also caused hyperthermia and increased mortality in rats.

  13. Spatial and reversal learning in the Morris water maze are largely resistant to six hours of REM sleep deprivation following training

    This first test of the role of REM (rapid eye movement) sleep in reversal spatial learning is also the first attempt to replicate a much cited pair of papers reporting that REM sleep deprivation impairs the consolidation of initial spatial learning in the Morris water maze. We hypothesized that REM sleep deprivation following training would impair both hippocampus-dependent spatial learning and learning a new target location within a familiar environment: reversal learning. A 6-d protocol was divided into the initial spatial learning phase (3.5 d) immediately followed by the reversal phase (2.5 d). During the 6 h following four or 12 training trials/day of initial or reversal learning phases, REM sleep was eliminated and non-REM sleep left intact using the multiple inverted flowerpot method. Contrary to our hypotheses, REM sleep deprivation during four or 12 trials/day of initial spatial or reversal learning did not affect training performance. However, some probe trial measures indicated REM sleep-deprivation–associated impairment in initial spatial learning with four trials/day and enhancement of subsequent reversal learning. In naive animals, REM sleep deprivation during normal initial spatial learning was followed by a lack of preference for the subsequent reversal platform location during the probe. Our findings contradict reports that REM sleep is essential for spatial learning in the Morris water maze and newly reveal that short periods of REM sleep deprivation do not impair concurrent reversal learning. Effects on subsequent reversal learning are consistent with the idea that REM sleep serves the consolidation of incompletely learned items. PMID:21677190

    Comparisons of high- and low-affinity [ 3 H]imipramine binding to whole brain homogenates from adult male and female rats of the Fawn-Hooded and Long-Evans strains were performed. Most strikingly, no significant differences were observed between the two strains in any of the binding parameters, indicating that brain [ 3 H]imipramine binding sites, which may be related to the serotonergic uptake process, appear normal in a strain of rats with serotonin platelet storage pool disease.

    The human RH locus appears to consist of two structural genes, D and CE, which map on the short arm p34-36 of chromosome 1 and specify a most complex system of blood-group genetic polymorphisms. Here we describe a family study of the Evans (also known as {open_quotes}D..{open_quotes}) phenotype, a codominant trait associated with both qualitative and quantitative changes in D-antigen expression. A cataract-causing mutation was also inherited in this family and was apparently cotransmitted with Evans, suggesting a chromosomal linkage of these two otherwise unrelated traits. Southern blot analysis and allele-specific PCR showed the linkage of Evans with a SphI RFLP marker and the presence of a hybrid gene in the RH locus. To delineate the pattern of gene expression, the composition and structure of Rh-polypeptide transcripts were characterized by reverse transcriptase-PCR and nucleotide sequencing. This resulted in the identification of a novel Rh transcript expressed only in the Evans-positive erythroid cells. Sequence analysis showed that the transcript maintained a normal open reading frame but occurred as a CE-D-CE composite in which exons 2-6 of the CE gene were replaced by the homologous counterpart of the D gene. This hybrid gene was predicted to encode a CE-D-CE fusion protein whose surface expression correlates with the Evans phenotype. The mode and consequence of such a recombination event suggest the occurrence, in the RH locus, of a segmental DNA transfer via the mechanism of gene conversion. 31 refs., 6 figs., 1 tab.

    The fundamental cause of overweight and obesity is consumption of calorie-dense foods. We have introduced a zero-calorie sweet sugar, d-psicose (d-allulose), a rare sugar that has been proven to have strong antihyperglycemic and antihyperlipidemic effects, and could be used as a replacement of natural sugar for the obese and diabetic subjects. Above mentioned efficacy of d-psicose (d-allulose) has been confirmed in our previous studies on type 2 diabetes mellitus (T2DM) model Otsuka Long-Evans Tokushima Fatty (OLETF) rats with short-term treatment. In this study we investigated the long-term effect of d-psicose in preventing the commencement and progression of T2DM with the mechanism of preservation of pancreatic β-cells in OLETF rats. Treated OLETF rats were fed 5% d-psicose dissolved in water and control rats only water. Nondiabetic control rats, Long-Evans Tokushima Otsuka (LETO), were taken as healthy control and fed water. To follow the progression of diabetes, periodic measurements of blood glucose, plasma insulin, and body weight changes were continued till sacrifice at 60 weeks. Periodic in vivo body fat mass was measured. On sacrifice, pancreas, liver, and abdominal adipose tissues were collected for various staining tests. d-Psicose prevented the commencement and progression of T2DM till 60 weeks through the maintenance of blood glucose levels, decrease in body weight gain, and the control of postprandial hyperglycemia, with decreased levels of HbA1c in comparison to nontreated control rats. This improvement in glycemic control was accompanied by the maintenance of plasma insulin levels and the preservation of pancreatic β-cells with the significant reduction in inflammatory markers. Body fat accumulation was significantly lower in the treatment group, with decreased infiltration of macrophages in the abdominal adipose tissue. Our findings suggest that the rare sugar d-psicose could be beneficial for the prevention and control of obesity and

    Obesity and type 2 diabetes (T2D) increase fracture risk; however, the association between obesity/T2D may be confounded by consumption of a diet high in fat, sucrose, and cholesterol (HFSC). The study objective was to determine the main and interactive effects of obesity/T2D and a HFSC diet on bone outcomes using hyperphagic Otuska Long Evans Tokushima Fatty (OLETF) rats and normophagic Long Evans Tokushima Otsuka (LETO) controls. At 8weeks of age, male OLETF and LETO rats were randomized to either a control (CON, 10 en% from fat as soybean oil) or HFSC (45 en% from fat as soybean oil/lard, 17 en% sucrose, and 1wt%) diet, resulting in four treatment groups. At 32weeks, total body bone mineral content (BMC) and density (BMD) and body composition were measured by dual-energy X-ray absorptiometry, followed by euthanasia and collection of blood and tibiae. Bone turnover markers and sclerostin were measured using ELISA. Trabecular microarchitecture of the proximal tibia and geometry of the tibia mid-diaphysis were measured using microcomputed tomography; whole-bone and tissue-level biomechanical properties were evaluated using torsional loading of the tibia. Two-factor ANOVA was used to determine main and interactive effects of diet (CON vs. HFSC) and obesity/T2D (OLETF vs. LETO) on bone outcomes. Hyperphagic OLEFT rats had greater final body mass, body fat, and fasting glucose than normophagic LETO, with no effect of diet. Total body BMC and serum markers of bone formation were decreased, and bone resorption and sclerostin were increased in obese/T2D OLETF rats. Trabecular bone volume and microarchitecture were adversely affected by obesity/T2D, but not diet. Whole-bone and tissue-level biomechanical properties of the tibia were not affected by obesity/T2D; the HFSC diet improved biomechanical properties only in LETO rats. Obesity/T2D, regardless of diet, negatively impacted the balance between bone formation and resorption and trabecular bone volume and

    Clinically, early life stress and anxiety disorders are associated with increased vulnerability for alcohol use disorders. In male rats, early life stress, imparted by adolescent social isolation, results in long-lasting increases in a number of behavioral risk factors for alcoholism, including greater anxiety-like behaviors and ethanol (EtOH) intake. Several recent studies have begun to use this model to gain insight into the relationships among anxiety measures, stress, EtOH intake, and neurobiological correlates driving these behaviors. As prior research has noted significant sex differences in the impact of adolescent stress on anxiety measures and EtOH drinking, the current study was conducted to determine if this same model produces an "addiction vulnerable" phenotype in female rodents. Female Long Evans rats were socially isolated (SI; 1/cage) or group housed (GH; 4/cage) for 6 weeks during adolescence. After this housing manipulation, behavioral assessment was conducted using the elevated plus maze, response to novelty in an open field environment, and the light/dark box. After behavioral testing, home cage EtOH drinking was assessed across an 8-week period. No group differences were detected in any of the behavioral measures of unconditioned anxiety-like behavior. Greater EtOH intake and preference were observed in SI females but these differences did not persist. The SI/GH model, which results in robust and enduring increases in anxiety measures and EtOH self-administration in male Long Evans rats, did not result in similar behavioral changes in female rats. These data, and that of others, suggest that adolescent social isolation is not a useful model with which to study neurobiological substrates linking antecedent anxiety and addiction vulnerability in female rats. Given the compelling epidemiological evidence that the relationship between chronic adolescent stress and alcohol addiction is particularly strong in women, there is clearly an urgent need

    Full Text Available Introduction. Alzheimer’s disease (AD causes progressive hippocampus dysfunctions leading to the impairment of learning and memory ability and low level of uptake rate of glucose in hippocampus. What is more, there is no effective treatment for AD. In this study, we evaluated the beneficial and protective effects of electroacupuncture in senescence-accelerated mouse prone 8 (SAMP8. Method. In the electroacupuncture paradigm, electroacupuncture treatment was performed once a day for 15 days on 7.5-month-old SAMP8 male mice. In the normal control paradigm and AD control group, 7.5-month-old SAMR1 male mice and SAMP8 male mice were grabbed and bandaged while electroacupuncture group therapy, in order to ensure the same treatment conditions, once a day, 15 days. Results. From the Morris water maze (MWM test, we found that the treatment of electroacupuncture can improve the spatial learning and memory ability of SAMP8 mouse, and from the micro-PET test, we proved that after the electroacupuncture treatment the level of uptake rate of glucose in hippocampus was higher than normal control group. Conclusion. These results suggest that the treatment of electroacupuncture may provide a viable treatment option for AD.

    A comparison study of Back Pain Functional Scale (BPFS) with Roland Morris Questionnaire (RMQ), Oswestry Disability Index (ODI) and Short Form 36-Health Survey (SF-36). The aim of this study is to investigate the correlation of BPFS with RMQ, ODI and SF-36. The primary goal in the treatment of patients with low back pain is to improve the patients' levels of activities and participation. Many questionnaires focusing on function have been developed in patients with low back pain. BPFS is one of these questionnaires. No studies have investigated the correlation of BPFS with ODI and SF-36. This study was conducted with 120 patients receiving outpatient and inpatient treatment in physiotherapy and rehabilitation units of a state hospital. BPFS, RMQ, ODI, SF-36 questionnaires were used to assess the disability in low back pain. Spearman and Pearson Correlation were used to compare the data obtained in the study. There was a good correlation among the five functional outcome measures (correlation r = -0.693 for BPFS/RMQ, r = -0.794 for BPFS/ODI, r = 0.697 for BPFS/SF-36 Physical function and r = 0.540 for BPFS/SF-36 Pain). BPFS demonstrated good correlation with RMQ, ODI, SF-36 physical function and SF-36 pain. 2.

    The effects of a sublethal dose of gamma-rays applied on the head on selected behavioral parameters were investigated in this study. Adult male Sprague-Dowley rats (n=9) were irradiated with a single dose of 20 Gy of gamma-rays from a 60 Co radiation source. The irradiated animals as well as sham-irradiated controls were tested daily in Morris water maze (MWM) (2 sessions per day) and in the open field test. The ability of spatial learning given by latency time to find the hidden platform was followed in MWM. The horizontal and vertical locomotion, the number of crossings of the center of the field and the washing behavior were recorded during an 8-minute test in the open field. The results obtained show, that radiation didn't altered significantly the dynamic of learning in MWM during the experiment. The level of horizontal and vertical locomotory activity in open field was lower in irradiated group in comparison with controls. The number of the crossings of the field's center, related to the level of anxiozity of animals was non-significantly lower in irradiated animals, whereas no differences in number of washing between both groups were detected. The results point to differences in radiosensitivity in various behavioral parameters in rats, maybe due to different level of their control and coordination in CNS. (authors)

    The purpose of this study was to assess the potential impact of public policies to regulate price discounting strategies on retail cigarette prices and advertising. Philip Morris USA (PM USA) has a policy designed to sanction stores violating state laws banning illegal tobacco sales to minors by temporarily suspending price discounting incentives. This study examined the impact of those sanctions on retail cigarette prices and sales promotion advertising. In November 2006, the California Attorney General's Office informed PM USA that 196 stores were found guilty of illegal underage sales. Of these, 109 stores that participated in the PM USA Retail Leaders Program were notified that their merchandising and/or promotional resources would be suspended for the month of April 2007. The remaining 87 stores were not sanctioned and served as a comparison group. Trained raters assessed advertising and prices of selected PM USA brands in these stores pre-penalty and during the penalty phase. There were no significant differences between sanctioned and non-sanctioned stores on median changes in price and sales promotion advertising from the pre-penalty to the penalty phase. The lack of impact on cigarette prices and advertising indicate that the PM USA policy may be flawed in its design or execution. If public policies are developed to restrain cigarette price discounting strategies, they should be crafted to ensure compliance and preclude possible compensatory actions by retailers.

    Ampakines have shown beneficial effects on cognition in selected animal models of learning. However, their ability to modify long-term spatial memory tasks has not been studied yet. This would lend credence to their possible value in treating disorders of cognition. We evaluated the actions of subchronic Org 26576 administration on spatial reference memory performance in the 5-day Morris water maze task in male Sprague-Dawley rats, at doses of 1, 3 and 10 mg/kg twice daily through intraperitoneal injection over 12 days. Org 26576 exerted a dose and time-dependent effect on spatial learning, with dosages of 3 and 10 mg/kg significantly enhancing acquisition on day 1. Globally, escape latency decreased significantly as the training days progressed in the saline and Org 26576-treated groups, indicating that significant and equal learning had taken place over the learning period. However, at the end of the learning period, all doses of Org 26576 significantly improved spatial memory storage/retrieval without confounding effects in the cued version of the task. Org 26576 offers early phase spatial memory benefits in rats, but particularly enhances search accuracy during reference memory retrieval. These results support its possible utility in treating disorders characterized by deficits in cognitive performance.

    Full Text Available Streets are a representation of cities, and the image of a city is a reflection of its home country. Although attempts to ensure harmonious spatial and environmental development in Ghanaian settlements date back to the colonial era, these efforts have minimal physical manifestation in the urban fabric of the city of Accra. The Independence Arch of Ghana, an important landmark in the urban fabric and history of Accra, lacks the striking vista and approach it deserves. This paper introduces the use of fractal analysis of street edges to understand the characteristics of the John Evans Atta Mills (JEAM High Street for developing recommendations to improve visibility along its stretch and the overall image of the city. The box-counting method with visual survey was used in research. The pertinent questions this paper seeks to address are as follows: What factors affect the visibility and imageability of JEAM High Street? What design aspects should be considered to improve urban visibility along JEAM High Street? What is the link of fractals to urban design and architecture? The paper recommends various design considerations and qualities to improve the urban visibility and imageability of JEAM High Street.

    Despite widespread cannabis use in humans, few rodent models exist demonstrating significant Δ⁹-tetrahydrocannabinol (THC) self-administration, possibly due to THC's co-occurring aversive effects, which impact drug reinforcement. Cannabis contains a number of phytocannabinoids in addition to THC, one of which, cannabidiol (CBD), has been reported to antagonize some of the aversive effects of THC. Given such effects of CBD, it is possible that it might influence THC intravenous self-administration in rodents. Accordingly, male and female Long-Evans rats were trained to self-administer THC over a 3-week period and then were assessed for the effects of CBD on responding for THC at 1:1 and 1:10 dose ratios or for the establishment of cocaine self-administration (as a positive control for drug self-administration). Consistent with previous research, THC self-administration was modest and only evident in a subset of animals (and unaffected by sex). Cocaine self-administration was high and evident in the majority of animals tested, indicating that the design was sensitive to drug reinforcement. There was no effect of CBD pretreatment on THC intravenous self-administration at any CBD:THC dose ratio. Future developments of animal models of THC self-administration and the examination of factors that affect its display remain important to establish procedures designed to assess the basis for and treatment of cannabis use and abuse.

    The present study examines the postnatal reproductive development of male rats following prenatal exposure to an atrazine metabolite mixture (AMM) consisting of the herbicide atrazine and its environmental metabolites diaminochlorotriazine, hydroxyatrazine, deethylatrazine, and deisopropylatrazine. Pregnant Long-Evans rats were treated by gavage with 0.09, 0.87, or 8.73 mg AMM/kg body weight (BW), vehicle, or 100 mg ATR/kg BW positive control, on gestation days 15 19. Preputial separation was significantly delayed in 0.87 mg and 8.73 mg AMM-exposed males. AMM-exposed males demonstrated a significant treatment-related increase in incidence and severity of inflammation in the prostate on postnatal day (PND) 120. A dose-dependent increase in epididymal fat masses and prostate foci were grossly visible in AMM-exposed offspring. These results indicate that a short, late prenatal exposure to mixture of chlorotriazine metabolites can cause chronic prostatitis in male LE rats. The mode of action for these effects is presently unclear.

  7. Markers for blood-brain barrier integrity: how appropriate is Evans blue in the 21st century and what are the alternatives?

    2015-10-01

    Full Text Available In recent years there has been a resurgence of interest in brain barriers and various roles their intrinsic mechanisms may play in neurological disorders. Such studies require suitable models and markers to demonstrate integrity and functional changes at the interfaces between blood, brain and cerebrospinal fluid. Studies of brain barrier mechanisms and measurements of plasma volume using dyes have a long-standing history, dating back to the late 19th-Century. Their use continues in spite of their known serious limitations in in vivo applications. These were well known when first introduced, but seem to have been forgotten since. Understanding these limitations is important because Evans blue is still the most commonly used marker of brain barrier integrity and those using it seem oblivious to problems arising from its in vivo application. The introduction of HRP in the mid 20th-Century was an important advance because its reaction product can be visualized at the electron microscopical level. Advantages and disadvantages these markers will be discussed together with a critical evaluation of alternative approaches. There is no single marker suitable for all purposes. A combination of different sized, visualisable dextrans and radiolabelled molecules currently seems to be the most appropriate approach for qualitative and quantitative assessment of barrier integrity.

    Maple syrup is used as a premium natural sweeter, and is known for being good for human health. In the present study, we investigate whether maple syrup is suitable as a sweetener in the management of type 2 diabetes using Otsuka Long-Evans Tokushima Fatty (OLETF) rats, a model of type 2 diabetes mellitus. OLETF rats develop type 2 diabetes mellitus by 30 weeks of age, and 60-week-old OLETF rats show hyperglycemia and hypoinsulinemia via pancreatic β-cell dysfunction. The administration of sucrose or maple syrup following an OGT test increased plasma glucose (PG) levels in OLETF rats, but the enhancement in PG following the oral administration of maple syrup was lower than in the case of sucrose administration in both 30- and 60-week-old OLETF rats. Although, the insulin levels in 30-week-old OLETF rats also increased following the oral administration of sucrose or maple syrup, no increase in insulin levels was seen in 60-week-old OLETF rats following the oral administration of either sucrose or maple syrup. No significant differences were observed in insulin levels between sucrose- and maple syrup-administered OLETF rats at either 30 or 60 weeks of age. The present study strongly suggests that the maple syrup may have a lower glycemic index than sucrose, which may help in the prevention of type 2 diabetes.

    This study aimed to determine whether taurine supplementation improves metabolic disturbances and diabetic complications in an animal model for type 2 diabetes. We investigated whether taurine has therapeutic effects on glucose metabolism, lipid metabolism, and diabetic complications in Otsuka Long-Evans Tokushima fatty (OLETF) rats with long-term duration of diabetes. Fourteen 50-week-old OLETF rats with chronic diabetes were fed a diet supplemented with taurine (2%) or a non-supplemented control diet for 12 weeks. Taurine reduced blood glucose levels over 12 weeks, and improved OGTT outcomes at 6 weeks after taurine supplementation, in OLETF rats. Taurine significantly reduced insulin resistance but did not improve β-cell function or islet mass. After 12 weeks, taurine significantly decreased serum levels of lipids such as triglyceride, cholesterol, high density lipoprotein cholesterol, and low density lipoprotein cholesterol. Taurine significantly reduced serum leptin, but not adiponectin levels. However, taurine had no therapeutic effect on damaged tissues. Taurine ameliorated hyperglycemia and dyslipidemia, at least in part, by improving insulin sensitivity and leptin modulation in OLETF rats with long-term diabetes. Additional study is needed to investigate whether taurine has the same beneficial effects in human diabetic patients. PMID:23114424

  10. Reduced hippocampal dendritic spine density and BDNF expression following acute postnatal exposure to di(2-ethylhexyl phthalate in male Long Evans rats.

    Directory of Open Access Journals (Sweden)

    Catherine A Smith

    Full Text Available Early developmental exposure to di(2-ethylhexyl phthalate (DEHP has been linked to a variety of neurodevelopmental changes, particularly in rodents. The primary goal of this work was to establish whether acute postnatal exposure to a low dose of DEHP would alter hippocampal dendritic morphology and BDNF and caspase-3 mRNA expression in male and female Long Evans rats. Treatment with DEHP in male rats led to a reduction in spine density on basal and apical dendrites of neurons in the CA3 dorsal hippocampal region compared to vehicle-treated male controls. Dorsal hippocampal BDNF mRNA expression was also down-regulated in male rats exposed to DEHP. No differences in hippocampal spine density or BDNF mRNA expression were observed in female rats treated with DEHP compared to controls. DEHP treatment did not affect hippocampal caspase-3 mRNA expression in male or female rats. These results suggest a gender-specific vulnerability to early developmental DEHP exposure in male rats whereby postnatal DEHP exposure may interfere with normal synaptogenesis and connectivity in the hippocampus. Decreased expression of BDNF mRNA may represent a molecular mechanism underlying the reduction in dendritic spine density observed in hippocampal CA3 neurons. These findings provide initial evidence for a link between developmental exposure to DEHP, reduced levels of BDNF and hippocampal atrophy in male rats.

    Full Text Available Diabetic nephropathy is one of the most significant microvascular complications in patients with type 2 diabetics. The concise mechanism of diabetic nephropathy is unknown and there is no successful treatment. The objective of study was to investigate effects of Chinese herbs (Tangshen Formula on diabetic nephropathy in Otsuka Long-Evans Tokushima Fatty (OLETF rats. OLETF rats and LETO rats were divided into four groups: LETO control, OLETF diabetics, OLETF diabetics treated with Tangshen Formula, and OLETF diabetics treated with Monopril. Body weight, blood glucose, and 24 h urinary proteins were measured once every four weeks. Blood samples and kidney tissues were obtained for analyses of total cholesterol, triglyceride, whole blood viscosity, plasma viscosity, and pathohistological examination at 36 and 56 weeksrespectively. Untreated OLETF rats displayed diabetic nephropathy over the study period. Treatment of OLETF rats with Tangshen Formula attenuated the increases in blood glucose, body weight, 24 h urinary protein content, serum total cholesterol, whole blood viscosity and plasma viscosity at certain time. Treatment with Tangshen Formula also reduced glomerulosclerotic index and interstitial fibrotic index seen in OLETF rats. In conclusion, Tangshen Formula could attenuate the development of diabetic nephropathy in OLETF rat diabetic model.

    A series of nine [Sb7W36O133Ln3M2(OAc)(H2O)8](17-) heterometallic anions (Ln3M2; Ln=La-Gd, M=Co; Ln=Ce, M=Ni and Zn) have been obtained by reacting 3 d metal disubstituted Krebs-type tungstoantimonates(III) with early lanthanides. Their unique tetrameric structure contains a novel {MW9O33} capping unit formed by a planar {MW6O24} fragment to which three {WO2} groups are condensed to form a tungstate skeleton identical to that of a hypothetical trilacunary derivative of the ɛ-Keggin cluster. It is shown, for the first time, that classical Anderson-Evans {MW6O24} anions can act as building blocks to construct purely inorganic large frameworks. Unprecedented reactivity in the outer ring of these disk-shaped species is also revealed. The Ln3M2 anions possess chirality owing to a {Sb4O4} cluster being encapsulated in left- or right-handed orientations. Their ability to self-associate in blackberry-type vesicles in solution has been assessed for the Ce3Co2 derivative. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Magnetic resonance imaging (MRI) contrast agents that specifically detect atherosclerotic plaque may be useful for the noninvasive detection of the plaque. We have recently developed a new contrast agent, Evans blue-DTPA-gadolinium (EB-DTPA-Gd), which selectively accumulates vascular lesions with endothelial removal. In this study, we examined whether EB-DTPA-Gd is also useful for in vivo imaging of atherosclerotic plaques. We used male apolipoprotein-E-deficient (ApoE-/-) mice of different ages (3, 6 and 12 months old) and age-matched male wild-type mice. After a single intravenous administration of EB-DTPA-Gd (160 microM/kg body weight), MRI T(1) signal was obtained in vivo. Increased signal intensity in the aortic wall was noted within 10-20 min after intravenous injection of EB-DTPA-Gd and was maintained for 30 min. The MRI enhancement in the aorta of ApoE-/- mice was increased in accordance with age, whereas no such enhancement was noted in wild-type mice. Histological examination demonstrated that there was a topological correlation between the site of MRI enhancement and that of atherosclerotic plaque. These results indicate that EB-DTPA-Gd is a useful MRI contrast medium for the in vivo detection of atherosclerotic plaques. Copyright (c) 2007 S. Karger AG, Basel.

    Male rats exposedin uteroto 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) display reduced fertility as a consequence of the direct action of TCDD on the epididymides, as well as delayed puberty and altered reproductive organ weights. The current study provides dose–response data for the reproductive effects of TCDD, administered during pregnancy, with an emphasis on the effects of TCDD on testicular, epididymal, and ejaculated sperm numbers.

    N-methyl-d-aspartate receptors (NMDARs) play a crucial role in spatial memory formation. In neuropharmacological studies their functioning strongly depends on testing conditions and the dosage of NMDAR antagonists. The aim of this study was to assess the immediate effects of NMDAR block by (+)MK-801 or memantine on short-term allothetic memory. Memory was tested in a working memory version of the Morris water maze test. In our version of the test, rats underwent one day of training with 8 trials, and then three experimental days when rats were injected intraperitoneally with low- 5 (MeL), high - 20 (MeH) mg/kg memantine, 0.1mg/kg MK-801 or 1ml/kg saline (SAL) 30min before testing, for three consecutive days. On each experimental day there was just one acquisition and one test trial, with an inter-trial interval of 5 or 15min. During training the hidden platform was relocated after each trial and during the experiment after each day. The follow-up effect was assessed on day 9. Intact rats improved their spatial memory across the one training day. With a 5min interval MeH rats had longer latency then all rats during retrieval. With a 15min interval the MeH rats presented worse working memory measured as retrieval minus acquisition trial for path than SAL and MeL and for latency than MeL rats. MK-801 rats had longer latency than SAL during retrieval. Thus, the high dose of memantine, contrary to low dose of MK-801 disrupts short-term memory independent on the time interval between acquisition and retrieval. This shows that short-term memory tested in a working memory version of water maze is sensitive to several parameters: i.e., NMDA receptor antagonist type, dosage and the time interval between learning and testing.

    An ability to assess longitudinal changes in health status is crucial for the outcome measures used in treatment efficacy trials. The aim of this study was to verify the responsiveness of the Italian versions of the Oswestry Disability Index (ODI) and the Roland Morris Disability Questionnaire (RMDQ) in subjects with subacute or chronic low back pain (LBP). At the beginning and end of an 8 week rehabilitation programme, 179 patients completed a booklet containing the ODI, the RMDQ, a 0-10 numerical rating scale (NRS), and the 36-item Short-Form Health Survey (SF-36). A global perception of change scale was also completed at the end of the programme, and collapsed to produce a dichotomous outcome (i.e. improved vs. not improved). Responsiveness was assessed by means of distribution methods [minimum detectable change (MDC); effect size (ES); standardised response mean (SRM)] and anchor-based methods (ROC curves). The MDC for the ODI and RMDQ was, respectively, 13.67 and 4.87; the ES was 0.53 and 0.68; and the SRM was 0.80 and 0.81. ROC analysis revealed an area under the curve of 0.71 for the ODI and 0.64 for the RMDQ, thus indicating discriminating capacity; the best cut-off point for the dichotomous outcome was 9.5 for the ODI (sensitivity 76% and specificity 63%) and 2.5 for the RMDQ (sensitivity 62% and specificity 55%). These estimates were comparable between the subacute and chronic subjects. Both the ODI and the RMDQ moderately correlated with the SF-36 and NRS (Spearman's and Pearson's correlation coefficients of >0.30). The Italian ODI and RMDQ proved to be sensitive in detecting clinical changes after conservative treatment for subacute and chronic LBP. Our findings are consistent with those published in the literature, thus allowing cross-cultural comparisons and stimulating cross-national studies.

    Cross-cultural translation and psychometric testing were performed. To cross-culturally translate the Oswestry Disability Index (ODI), Roland-Morris Disability Questionnaire (RDQ), and Quebec Back Pain Disability Scale (QDS) into Persian, and then investigate the psychometric properties of the Persian versions produced. To the authors' knowledge, there is no validated instrument to measure functional status in Persian-speaking patients with low back pain (LBP) in Iran. To our knowledge, the widely used back-specific measures, the ODI, RDQ, and QDS, have not been translated and validated for Persian-speaking patients with LBP. The translation and cross-cultural adaptation of the original questionnaires were performed in accordance with published guidelines. A total of 100 patients with chronic LBP were asked to complete a questionnaire booklet (the Persian versions of the ODI, RDQ, QDS, Short Form Health Survey (SF-36), and visual analog scale measure of pain). There were 31 randomly select patients with chronic LBP asked to complete the second questionnaire booklet 24 hours later. The Cronbach-alpha for the ODI, RDQ, and QDS was 0.75, 0.83, and 0.92, respectively. The ODI, RDQ, and QDS showed excellent test-retest reliability (intraclass correlation coefficient = 0.91, 0.86, and 0.86, respectively) (P < 0.01). The correlation among the ODI, RDQ, QDS and physical functioning scales of the SF-36 was -0.66, -0.62, and -0.69, respectively (P < 0.001). The correlation among the ODI, RDQ, and QDS and visual analog scale was 0.54, 0.36, and 0.46, respectively (P < 0.001). The Persian versions of the ODI, RDQ, and QDS are reliable and valid instruments to measure functional status in Persian-speaking patients with LBP. They are simple and fast scales, and the use of them can be recommended in a clinical setting and future outcome studies in Iran.

    The current study applied a rodent-based Morris water maze (MWM) protocol to an investigation of search performance differences between young and older adult humans. To investigate whether similar age-related decline in search performance could be seen in humans based on the rodent-based protocol, we implemented a virtual MWM (vMWM) that has characteristics similar to those of the MWM used in previous studies of spatial learning in mice. Through the use of a proximity to platform measure, robust differences were found between healthy young and older adults in search performance. After dividing older adults into good and poor performers based on a median split of their corrected cumulative proximity values, the age effects in place learning were found to be largely related to search performance differences between the young and poor-performing older adults. When compared with the young, poor-performing older adults exhibited significantly higher proximity values in 83% of 24 place trials and overall in the probe trials that assessed spatial learning in the absence of the hidden platform. In contrast, good-performing older adults exhibited patterns of search performance that were comparable with that of the younger adults in most place and probe trials. Taken together, our findings suggest that the low search accuracy in poor-performing older adults stemmed from potential differences in strategy selection, differences in assumptions or expectations of task demands, as well as possible underlying functional and/or structural changes in the brain regions involved in vMWM search performance.

    Nitric oxide (NO) is an atypical neurotransmitter that causes changes in cognition. Nitric oxide synthase (NOS) and guanylate cyclase (GC) inhibitors have been shown to exert some effects on cognition in previous studies; however, the findings have been controversial. This study was aimed at understanding the effects of an NOS inhibitor, 7-nitroindazole (7-NI), and a guanylate cyclase inhibitor, 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ), on spatial memory in modified elevated plus maze (mEPM), Morris water maze (MWM), and radial arm maze (RAM) tests. Male Balb-c mice were treated via intraperitoneal injections with 7-NI (15 mg/kg), ODQ (3, 10 mg/kg), L-arginine (100 mg/kg) + 7-NI (15 mg/kg), or physiological saline. ODQ (3 mg/kg) and 7-NI (15 mg/kg) significantly increased the second-day latency in the mEPM test. 7-NI (15 mg/kg) and ODQ (10 mg/kg) significantly increased the escape latency in second, third, and fourth sessions, decreased the time spent in the escape platform's quadrant, and increased the mean distance to the platform in the probe trial of the MWM test. ODQ (3, 10 mg/kg) and 7-NI (15 mg/kg) significantly increased the number of errors, whereas only 7-NI increased the latency in the RAM test. The administration of L-arginine (100 mg/kg) prior to 7-NI inverted the effects of 7-NI, which supports the role of NO on cognition. Our study shows that the NO/cGMP/GS pathway can regulate spatial memory in mice.

    Inhibition of phosphodiesterase 5 (PDE) improved recognition memory and counteracted spatial learning impairment induced by nitric oxide synthase (NOS) inhibition in recent studies. Aim of this study was to investigate effects of rolipram, a PDE4 inhibitor and zaprinast, a PDE5 inhibitor, on learning and memory in Morris water maze (MWM) and radial arm maze (RAM) tests in naive mice. Male Balb-c mice were treated subchronically with zaprinast (3 and 10 mg/kg) and rolipram (0.05 and 0.1 mg/kg) for 6 days in the MWM test and acutely before the retention trial of radial arm maze test. Rolipram (0.05 and 0.1 mg/kg) significantly decreased escape latency between 2(nd) and 5(th) sessions, while zaprinast (10 mg/kg) significantly decreased escape latency only in 2(nd) session. Rolipram (0.05 and 0.1 mg/kg) and zaprinast (10 mg/kg) significantly increased time spent in escape platform's quadrant in probe trial of MWM test; only rolipram decreased mean distance to platform, while zaprinast had no effect on mean distance to platform. Zaprinast (3 and 10 mg/kg) significantly decreased number of errors compared to control group, while rolipram (0.05 and 0.1mg/kg) had no effect on number of errors in retention trial of RAM test. Rolipram (0.05 and 0.1 mg/kg) and zaprinast (10 mg/kg) significantly decreased time spent to complete retention trial (latency) compared to control group. Our study revealed that both zaprinast and rolipram enhanced spatial memory in MWM, while zaprinast seems to have more memory enhancing effects compared to rolipram in radial arm maze test. © Georg Thieme Verlag KG Stuttgart · New York.

    The infralimbic medial prefrontal cortex (IL) has been posited as a common node in distinct neural circuits that mediate the extinction of appetitive and aversive conditioning. However, appetitive extinction is typically assessed using instrumental conditioning procedures, whereas the extinction of aversive conditioning is customarily studied using Pavlovian assays. The role of the IL in the extinction of appetitive Pavlovian conditioning remains underexplored. We investigated the involvement of the IL and prelimbic medial prefrontal cortex (PrL) in appetitive extinction in Pavlovian and instrumental conditioning assays in male, Long-Evans rats. Following acquisition, a gamma-aminobutyric acid agonist solution (0.03 nmol muscimol; 0.3 nmol baclofen; 0.3 μl/side) was bilaterally microinfused into the IL or PrL to pharmacologically inactivate each region before the first extinction session. Compared to saline, PrL inactivation did not affect the acquisition of extinction or the recall of extinction memory 24-h later. IL inactivation caused a more rapid extinction of Pavlovian conditioning, but had no effect on the extinction of instrumental conditioning or extinction recall. IL inactivation during a Pavlovian conditioning session in which conditioned stimulus (CS) trials were paired with sucrose did not affect CS-elicited behaviour, but increased responding during intervals that did not contain the CS. The same manipulation did not impact lever pressing for sucrose. These findings suggest that the IL may normally maintain Pavlovian conditioned responding when an anticipated appetitive CS is unexpectedly withheld, and that this region has distinct roles in the expression of Pavlovian conditioning when an appetitive unconditioned stimulus is either presented or omitted.

    Individuals suffering from posttraumatic stress disorder (PTSD) frequently report disturbances in sexual functioning in addition to alterations in their affective behaviors. Notably, maladaptive cognitions and dysfunctional behaviors are perpetuated by the emergence of the intrusive thoughts that characterize the disorder. In rats, reminders of a traumatic event designed to simulate intrusive thoughts are associated with impairments in affective, social, and sexual behaviors. The current study examined the relationship between the memory for a traumatic event and changes in sexual and affective behaviors in male Long-Evans rats (N = 36). The trauma featured a combination stressor consisting of simultaneous exposure to a footshock and the odor of soiled cat litter. Memory for the trauma was reactivated by re-exposures to the context of the trauma in the absence of stressors and confirmed by assessing the percentage of time spent freezing. Following the second and final reminder, traumatized males exhibited reduced sexual motivation and increased anxiety, signified by longer latencies to achieve their first mount on a post-stress test of sexual behavior, and longer latencies to begin feeding in a novel environment, respectively. Correlational analyses revealed that decreased sexual motivation and heightened anxiety were predicted by the memory for the trauma as indicated by the time spent freezing during the re-exposures. The findings from the current study have implications for understanding the relationship between stress and sexual functioning and indicate that the impairments in sexual behavior that often occur in individuals with PTSD may be impacted by their memory for the trauma.

    To study effects of dietary Cu and Fe levels on the onset of hepatitis in Long-Evans Cinnamon (LEC) rats, female rats (40 days old) were fed a semipurified diet containing 0.1 or 10 mg Cu/kg and 1.5 or 150 mg Fe/kg in a 2 x 2 factorial arrangement for 35 days. At 75 days after birth, LEC rats (+Cu-Fe) fed a Cu-sufficient but Fe-deficient diet (Cu, 10 mg/kg; Fe, 1.5 mg/kg) showed jaundice, with lethargy, anorexia, and malaise. The biochemical variables relating to liver function were significantly increased compared to three other groups, a Cu- and Fe-deficient (-Cu-Fe) group, a Cu-deficient but Fe-sufficient (-Cu+Fe) group, and a Cu and Fe sufficient (+Cu+Fe) group. Furthermore, the +Cu-Fe rat liver showed massive necrosis with huge nuclei. The other three groups presented no biochemical and histological findings of hepatitis. Hepatic Cu and metallothionein concentrations were 289 {+-} 87 (mean {+-} SD) {mu}g/g liver and 8.7 {+-} 1.8 mg/g liver, respectively, in the +Cu-Fe rats. However, in the +Cu+Fe group the values were 196 {+-} 28 {mu}g Cu/g liver and 10.8 {+-} 1.0 mg/g liver. Hepatic Fe deposition was not influenced significantly by the dietary Cu level. The +Cu-Fe group with jaundice showed the highest free Cu concentration in the liver among the four groups, but the hepatic free Fe concentration was similar to those in the -Cu+Fe and +Cu+Fe groups. Our results indicate that an Fe-deficient diet enhances the deposition of hepatic Cu due to increased absorption of Cu from the gastrointestinal tract. This deposition stimulated the onset of hepatitis. (orig.)

    The increasing spatial and temporal complexity of models demands methods capable of ranking the influence of their large numbers of parameters. This question specifically arises in assessment studies on the consequences of the Fukushima accident. Sensitivity analysis aims at measuring the influence of input variability on the output response. Generally, two main approaches are distinguished (Saltelli, 2001, Iooss, 2011): - Screening approach, less expensive in computation time and allowing to identify non influential parameters; - Measures of importance, introducing finer quantitative indices. In this category, there are regression-based methods, assuming a linear or monotonic response (Pearson coefficient, Spearman coefficient), and variance-based methods, without assumptions on the model but requiring an increasingly prohibitive number of evaluations when the number of parameters increases. These approaches are available in various statistical programs (notably R) but are still poorly integrated in modelling platforms of radioecological risk assessment. This work aimed at illustrating the benefits of sensitivity analysis in the course of radioecological risk assessments This study used two complementary state-of-art global sensitivity analysis methods: - The screening method of Morris (Morris, 1991; Campolongo et al., 2007) based on limited model evaluations with a one-at-a-time (OAT) design; - The variance-based Sobol' sensitivity analysis (Saltelli, 2002) based a large number of model evaluations in the parameter space with a quasi-random sampling (Owen, 2003). Sensitivity analyses were applied on a dynamic Soil-Plant Deposition Model (Gonze et al., submitted to this conference) predicting foliar concentration in weeds after atmospheric radionuclide fallout. The Soil-Plant Deposition Model considers two foliage pools and a root pool, and describes foliar biomass growth with a Verhulst model.

    Cross-sectional study. To determine the correlation between SF-36 (a measure for overall health status in patients) and Oswestry-Disability Index (ODI) or Rolland-Morris Disability Questionnaire (RMDQ) confined to spine according to the type of pain from the spine. Data showed moderate correlation between ODI and SF-36 Physical Component Score (PCS), Physical Functioning (PF) (r=-0.46), Physical Role Functioning (RP) (r=-0.284), Bodily Pain (BP) (r=-0.327), and Mental Component Score (MCS), Emotional Role Functioning (r=-0.250), Social Role Functioning (r=0.254), Vitality (r=0.296). Between January 1, 2008 and December 31, 2013, a total of 69 patients were enrolled in this study. They were diagnosed with lumbar spinal stenosis and underwent decompression surgery such as laminotomy in this hospital. The 3 standardized questionnaires (ODI, RMDQ, and SF-36) were given to these patients, at least 1 year after the surgery. ODI and SF-36 had a statistically significant (P=0.001) and moderate correlation. Small correlations were also seen between Physical Functioning (r=-0.46), Physical Role Functioning (r=-0.284), and Bodily Pain (r=-0.327) of SF-36 PCS and ODI, and between Emotional Role Functioning (r=-0.250), Social Role Functioning (r=-0.254), and Vitality (r=-0.296) of SF-36 Mental Component Score and ODI. Items in ODI for the level of pain while standing and traveling were mostly related to axial back pain, while item of lifting was related to referred buttock pain. Sleeping disturbance section in the ODI was mainly caused by radiated leg pain. In addition, RMDQ was also associated to the 3 types of pain. Moderate correlation was found between ODI or RMDQ as a condition-specific outcome and the SF-36, indicating overall health status. ODI was found to be a more adequate measure to evaluate axial back pain rather than referred pain or radiating pain. RMDQ was adequate to measure the health status and to evaluate the 3 types of spine pain. These 3 instruments could

    The aim of this study was to examine the acute toxicity of TCDD in a rat strain other than the Sprague-Dawley (S-D) rat. Doses for the biochemical study were selected based on an acute range-finding study, which indicated that Long-Evans (L-E) rats are somewhat less susceptible to TCDD toxicity than are S-D rats. Male L-E rats were dosed orally with 10, 20, 45, 67, 100 and 150 [mu]g/kg TCDD. Body weight and feed intake were dose-dependently decreased prior to killing of the animals. Eight days after dosing, animals were killed and tryptophan, total T[sub 4] (TT[sub 4]) and total T[sub 3] (TT[sub 3]) levels were determined in serum, whereas the activities of ethoxy-resorufin-O-deethylase (EROD), phosphoenolpyruvate carboxykinase (PEPCK), [gamma]-glutamyl transpeptidase ([gamma]-GT) and tryptophan 2,3-dioxygenase (TdO) were measured in liver. EROD activity was fully induced at all doses studied, indicating that as in S-D rats, Ah-receptor-mediated effects do not seem to play any major role in the acute toxicity of TCDD in this rat strain either. Hepatic PEPCK activity was dose-dependently decreased in a similar dose range as in S-D rats, indicating inhibition of gluconeogenesis. Feed intake was dose-dependently decreased as a result of a dose-dependent elevation in serum tryptophan levels, which in turn were related to reduced liver TdO activity. Hepatic [gamma]-GT activity was also dose-dependently reduced. However, unlike in S-D rats, these dose-responses occurred in a higher dose range than the reduction of PEPCK activity which appears to be the explanation for the decreased susceptibility of L-E rats to TCDD. Serum TT[sub 4] levels were significantly decreased at all doses, whereas the serum concentration of TT[sub 3] appeared unaffected.

    Clinical studies demonstrate frequent co-existence of nicotine and alcohol abuse and suggest that this may result, in part, from the ready access to and intake of fat-rich diets. Whereas animal studies show that high-fat diet intake in adults can enhance the consumption of either nicotine or ethanol and that maternal consumption of a fat-rich diet during pregnancy increases operant responding for nicotine in offspring, little is known about the impact of dietary fat on the co-abuse of these two drugs. The goal of this study was to test in Long-Evans rats the effects of perinatal exposure to fat on the co-use of nicotine and ethanol, using a novel paradigm that involves simultaneous intravenous (IV) self-administration of these two drugs. Fat- vs. chow-exposed offspring were characterized and compared, first in terms of their nicotine self-administration behavior, then in terms of their nicotine/ethanol self-administration behavior, and lastly in terms of their self-administration of ethanol in the absence of nicotine. The results demonstrate that maternal consumption of fat compared to low-fat chow during gestation and lactation significantly stimulates nicotine self-administration during fixed-ratio testing. It also increases nicotine/ethanol self-administration during fixed-ratio and dose-response testing, with BEC elevated to 120 mg/dL, and causes an increase in breakpoint during progressive ratio testing. Of particular note is the finding that rats perinatally exposed to fat self-administer significantly more of the nicotine/ethanol mixture as compared to nicotine alone, an effect not evident in the chow-control rats. After removal of nicotine from the nicotine/ethanol mixture, this difference between the fat- and chow-exposed rats was lost, with both groups failing to acquire the self-administration of ethanol alone. Together, these findings suggest that perinatal exposure to a fat-rich diet, in addition to stimulating self-administration of nicotine, causes

    Hepatic steatosis has risen rapidly in parallel with a dramatic increase in obesity. The aim of this study was to determine whether the herbal composition Gambigyeongsinhwan (4) (GGH(4)), composed of Curcuma longa L. (Zingiberaceae), Alnus japonica (Thunb.) Steud. (Betulaceae), and the fermented traditional Korean medicine Massa Medicata Fermentata, regulates hepatic steatosis and inflammation. The effects of GGH(4) on hepatic steatosis and inflammation in Otsuka Long-Evans Tokushima fatty (OLETF) rats and HepG2 cells were examined using Oil red O, hematoxylin and eosin, and toluidine blue staining, immunohistochemistry, quantitative real-time polymerase chain reaction, and peroxisome proliferator-activated receptor α (PPARα) transactivation assay. Administration of GGH(4) to OLETF rats improved hepatic steatosis and lowered serum levels of alanine transaminase, total cholesterol, triglycerides, and free fatty acids. GGH(4) increased mRNA levels of fatty acid oxidation enzymes (ACOX, HD, CPT-1, and MCAD) and decreased mRNA levels of lipogenesis genes (FAS, ACC1, C/EBPα, and SREBP-1c) in the liver of OLETF rats. In addition, infiltration of inflammatory cells and expression of inflammatory cytokines (CD68, TNFα, and MCP-1) in liver tissue were reduced by GGH(4). Treatment of HepG2 cells with a mixture of oleic acid and palmitoleic acid induced significant lipid accumulation, but GGH(4) inhibited lipid accumulation by regulating the expression of hepatic fatty acid oxidation and lipogenic genes. GGH(4) also increased PPARα reporter gene expression. These effects of GGH(4) were similar to those of the PPARα activator fenofibrate, whereas the PPARα antagonist GW6471 reversed the inhibitory effects of GGH(4) on lipid accumulation in HepG2 cells. These results suggest that GGH(4) inhibits obesity-induced hepatic steatosis and that this process may be mediated by regulation of the expression of PPARα target genes and lipogenic genes. GGH(4) also suppressed obesity

    In the present research we have investigated the distribution of the sugar residues of the glycoconjugates in the prepubertal and postpubertal testes of a subject with Morris's syndrome (CAIS, Complete Androgen Insensitivity Syndrome). For this purpose a battery of six horseradish peroxidase-conjugated lectins was used (SBA, PNA, WGA, ConA, LTA and UEAI). We have obtained a complete distributional map of the terminal and sub-terminal oligosaccharides in the tunica albuginea, interstitial tissue, lamina propria of the seminiferous tubules, Leydig cells, Sertoli cells, spermatogonia, mastocytes and endothelial cells. Furthermore the present study has shown that a large amount of sugar residues were detectable in the prepubertal and postpubertal testes but that some differences exist with particular regard to the Sertoli cells. The Sertoli cells and the Leydig cells of the retained prepubertal testis of the patient affected by Morris's syndrome were characterized by the presence of alpha-L-fucose, which was absent in the retained prepubertal testis of the normal subjects. Comparing the results on the postpubertal testis with those obtained on the same aged testis of healthy subjects we have demonstrated that alpha-L-fucose in the Sertoli and Leydig cells and D-galactose-N-acetyl-D-galactosamine in the Leydig cells are a unique feature of the subject affected by Morris's syndrome. D-galactose (ss1,3)-N-acetyl-D-galactosamine and sialic acid, which are present in the Leydig cells of the normal testis were never observed in the same cells of the postpubertal testis of the CAIS patient.

    Cross-culturally adapt and validate the Igbo Roland Morris Disability Questionnaire. Cross-cultural adaptation, test-retest, and cross-sectional psychometric testing. Roland Morris Disability Questionnaire was forward and back translated by clinical/non-clinical translators. An expert committee appraised the translations. Twelve participants with chronic low back pain pre-tested the measure in a rural Nigerian community. Internal consistency using Cronbach's alpha; test-retest reliability using intra-class correlation coefficient and Bland-Altman plot; and minimal detectable change were investigated in a convenient sample of 50 people with chronic low back pain in rural and urban Nigeria. Pearson's correlation analyses using the eleven-point box scale and back performance scale, and exploratory factor analysis were used to examine construct validity in a random sample of 200 adults with chronic low back pain in rural Nigeria. Ceiling and floor effects were investigated in the two samples. Modifications gave the option of interviewer-administration and reflected Nigerian social context. The measure had excellent internal consistency (α = 0.91) and intraclass correlation coefficient (ICC =0.84), moderately high correlations (r > 0.6) with performance-based disability and pain intensity, and a predominant uni-dimensional structure, with no ceiling or floor effects. Igbo Roland Morris Disability Questionnaire is a valid and reliable measure of pain-related disability. Implications for rehabilitation Low back pain is the leading cause of years lived with disability worldwide, and is particularly prevalent in rural Nigeria, but there are no self-report measures to assess its impact due to low literacy rates. This study describes the cross-cultural adaptation and validation of a core self-report back pain specific disability measure in a low-literate Nigerian population. The Igbo Roland Morris Disability Questionnaire is a reliable and valid measure of self

    All of the experimental studies of the past 25 years combined and the meta-analyses of their findings have not advanced our knowledge of the lateralization of language in bilingual speakers one bit. We are left with a clutter of inherently uninterpretable contradictory results. Successive studies do not contribute a single brick to the edifice or a single piece to the puzzle-only more confusion. study is no exception. So far, there has been no demonstration of the validity of any experimental paradigm claiming to measure degree of language laterality in bilingual speakers. Experimentation is pointless unless the nature of what is alleged to be lateralized is clearly defined and the validity of the measures employed has been established. Because of the lack of validity of the paradigms used in bilingual laterality studies, experiments and meta-analyses of their findings cannot have any scientific significance. Like their predecessors, Evans et al. pay lip service to a number of methodological problems, but ignore their implications and simply carry on anyway. The authors ought to demonstrate, rather than assume, that degree of visual half-field advantage for single words corresponds to degree of lateralization of any component of language (even if only of words).

    The majority of validation done on the Roland-Morris Disability Questionnaire (RMDQ) has been in patients with mild or moderate disability. There is paucity of research focusing on the psychometric quality of the RMDQ in patients with severe disability. To evaluate the psychometric quality of the RMDQ in patients with severe disability. Observational clinical study. The sample consisted of 214 patients with painful vertebral compression fractures who underwent vertebroplasty or kyphoplasty. The 23-item version of the RMDQ was completed at two time points: baseline and 30-day postintervention follow-up. With the two-parameter logistic unidimensional item response theory (IRT) analyses, we derived the range of scores that produced reliable measurement and investigated the minimal clinically important difference (MCID). Scores for 214 (100%) patients at baseline and 108 (50%) patients at follow-up did not meet the reliability criterion of 0.90 or higher, with the majority of patients having disability due to back pain that was too severe to be reliably measured by the RMDQ. Depending on methodology, MCID estimates ranged from 2 to 8 points and the proportion of patients classified as having experienced meaningful improvement ranged from 26% to 68%. A greater change in score was needed at the extreme ends of the score scale to be classified as having achieved MCID using IRT methods. Replacing items measuring moderate disability with items measuring severe disability could yield a version of the RMDQ that better targets patients with severe disability due to back pain. Improved precision in measuring disability would be valuable to clinicians who treat patients with greater functional impairments. Caution is needed when choosing criteria for interpreting meaningful change using the RMDQ. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Learning and memory as well as long-term potentiation (LTP depend on Ca2+ influx through the NMDA-type glutamate receptor (NMDAR and the resulting activation of the Ca2+ and calmodulin-dependent protein kinase (CaMKII. Ca2+ influx via the NMDAR triggers CaMKII binding to the NMDAR for enhanced CaMKII accumulation at post-synaptic sites that experience heightened activity as occurring during LTP. Previously, we generated knock-in (KI mice in which we replaced two residues in the NMDAR GluN2B subunit to impair CaMKII binding to GluN2B. Various forms of LTP at the Schaffer collateral synapses in CA1 are reduced by 50%. Nevertheless, working memory in the win-shift 8 arm maze and learning of the Morris water maze (MWM task was normal in the KI mice although recall of the task was impaired in these mice during the period of early memory consolidation. We now show that massed training in the MWM task within a single day resulted in impaired learning. However, learning and recall of the Barnes maze task and contextual fear conditioning over one or multiple days were surprisingly unaffected. The differences observed in the MWM compared to the Barnes maze and contextual fear conditioning suggest a differential involvement of CaMKII and the specific interaction with GluN2B, probably depending on varying degrees of stress, cognitive demand or even potentially different plasticity mechanisms associated with the diverse tasks.

    The authors are developing techniques for the study of perfused solid tumors by NMR. Tissue-isolated solid hepatomas were grown to 1-2 cm diameter as described previously. The arterial supply was isolated and the tumors perfused (0.5 - 1.0 ml/min) in vitro at 25 C with a 15% suspension of red blood cells in Krebs-Henseliet solution. 31 P-NMR spectra were acquired at 162 MHz in a specially-designed NMR probe using a solenoidal coil. Intracellular pH (monitored from the chemical shift of inorganic phosphate) and ATP levels were stable for up to 6 hrs during perfusion. During 30 min of global ischemia, ATP decreased by 75% and pH fell from 7.0 to 6.7. These changes were reversed by 1 hr reperfusion. In addition to ATP and phosphate, the spectra included a large resonance due to phosphomonoesters, as well as peaks consistent with glycerylphosphocholine, glyceryl-phosphoethanolamine, phosphocreatine, NAD, and UDPG. However, the most novel feature of the spectra was the presence of an unidentified peak in the phosphonate region (+ 16.9 ppm). The peak was not present in spectra of muscle, liver, brain, kidney, or fat tissues excised from the same animals. They are presently attempting to identify the compound that gives rise to this peak and to establish its metabolic origin

    Adipocyte lipid accumulation due to impaired fatty acid oxidation causes adipocyte hypertrophy and adipose tissue increment, leading to obesity. The aim of this study was to determine the antiobesity effects of the herbal composition Gambigyeongsinhwan (4) (GGH(4)) composed of Curcuma longa L. (Zingiberaceae), Alnus japonica (Thunb.) Steud. (Betulaceae), and the fermented traditional Korean medicine Massa Medicata Fermentata. The effects of GGH(4) and the individual components on lipid accumulation in 3T3-L1 adipocytes and body weight gain in Otsuka Long-Evans Tokushima Fatty (OLETF) rats were examined using Oil red O staining, hematoxylin and eosin staining, quantitative real-time PCR, and peroxisome proliferator-activated receptor α (PPARα) transactivation assay. GGH(4), individual components, and an active principle of Curcuma longa curcumin inhibited lipid accumulation and mRNA levels of adipocyte-specific genes (PPARγ, aP2, and C/EBPα) in 3T3-L1 adipocytes compared with control cells. Treatment with GGH(4), the individual components or curcmumin increased mRNA levels of mitochondrial (CPT-1, MCAD, and VLCAD) and peroxisomal (ACOX and thiolase) PPARα target genes. GGH(4) and the individual components also increased PPARα reporter gene expression compared with control cells. These effects were most prominent in GGH(4)-treated cells. However, the PPARα antagonist GW6471 reversed the inhibitory effects of GGH(4) on adipogenesis. An in vivo study showed that GGH(4) decreased body weight gain, adipose tissue mass, and visceral adipocyte size with increasing mRNA levels of adipose tissue PPARα target genes in OLETF rats. These results demonstrate that GGH(4) has an antiobesity effects through the inhibition of adipocyte lipid accumulation, and this process may be mediated in part through adipose PPARα activation.

    A prospective cohort. The aim of this study was to compare the responsiveness of a patient specific outcome measure with the Oswestry Disability Index v2.1 (ODI) and the Roland and Morris Disability Questionnaire (RMDQ) for patients with mild to moderate subacute and chronic low back pain. Patient specific outcome measures allow individuals to select and rate the relative importance of activities they consider of greatest relevance. However, there is a paucity of research reporting the responsiveness of these measures for patient with back pain. Two hundred and one patients were assessed at baseline and 12 months using the patient specific activity questionnaire (PSAQ), the ODI, the RMDQ, and a transition rating scale. The latter was used to categorize patients into 3 groups (better, same or worse). Effect size statistics, receiver operating characteristic curves and 1-way between groups analysis of variance were used in the analysis. All instruments were able to detect improvements in back pain as measured by the transition rating scale. In this improved group effect sizes were large for the PSAQ (1.08 to 1.31) and ODI (-0.88 to -1.00) but only moderate for the RMDQ (-0.70 to -0.74). In the deteriorated group effect sizes were moderate to large for the ODI (0.61 to 1.16) and RMDQ (0.69 to 1.25), but small for the PSAQ (-0.16 to -0.26). The areas under receiver operator characteristic curves for the ODI, PSAQ, and RMDQ, respectively were: 0.75 (95% CI 0.68 to 0.82), 0.75 (95% CI 0.68 to 0.82) and 0.69 (95% CI 0.61 to 0.76). The PSAQ was highly responsive to change in patients who report improvement in back symptoms but unlike the ODI and RMDQ was unable to detect deterioration. Overall, the ODI was more responsive than either the PSAQ or the RMDQ.

    Physical functioning is a core outcome domain to be measured in nonspecific low back pain (NSLBP). A panel of experts recommended the Roland-Morris Disability Questionnaire (RMDQ) and Oswestry Disability Index (ODI) to measure this domain. The original 24-item RMDQ and ODI 2.1a are recommended by their developers. The purpose of this study was to evaluate whether the 24-item RMDQ or the ODI 2.1a has better measurement properties than the other to measure physical functioning in adult patients with NSLBP. Bibliographic databases (MEDLINE, Embase, CINAHL, SportDiscus, PsycINFO, and Google Scholar), references of existing reviews, and citation tracking were the data sources. Two reviewers selected studies performing a head-to-head comparison of measurement properties (reliability, validity, and responsiveness) of the 2 questionnaires. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist was used to assess the methodological quality of these studies. The studies' characteristics and results were extracted by 2 reviewers. A meta-analysis was conducted when there was sufficient clinical and methodological homogeneity among studies. Nine articles were included, for a total of 11 studies assessing 5 measurement properties. All studies were classified as having poor or fair methodological quality. The ODI displayed better test-retest reliability and smaller measurement error, whereas the RMDQ presented better construct validity as a measure of physical functioning. There was conflicting evidence for both instruments regarding responsiveness and inconclusive evidence for internal consistency. The results of this review are not generalizable to all available versions of these questionnaires or to patients with specific causes for their LBP. Based on existing head-to-head comparison studies, there are no strong reasons to prefer 1 of these 2 instruments to measure physical functioning in patients with NSLBP, but studies of higher

In this study, we compared the effects of the combination of Cil and amlodipine (Aml, which is an L-type CCB, with an angiotensin (Ang II receptor blocker on diabetic cardiorenal damage in spontaneously type 2 diabetic rats. Seventeen-week-old Otsuka Long-Evans Tokushima Fatty rats were randomly assigned to receive Cil, Aml, valsartan (Val, Cil + Val, Aml + Val, or a vehicle (eight rats per group for 22 weeks. Antihypertensive potencies were nearly equal among the CCB monotherapy groups and the combination therapy groups. The lowering of blood pressure by either treatment did not significantly affect the glycemic variables. However, exacerbations of renal and heart failure were significantly suppressed in rats administered Cil or Val, and additional suppression was observed in those administered Cil + Val. Although Val increased the renin–Ang system, Aml + Val treatment resulted in additional increases in these parameters, while Cil + Val did not show such effects. Furthermore, Cil increased the ratio of Ang-(1–7 to Ang-I, despite the fact that Val and Aml + Val decreased the Ang-(1–7 levels. These actions of Cil + Val might be due to their synergistic inhibitory effect on the activity of the SNS, and on aldosterone secretion through N-type calcium channel antagonism and Ang II

    Full Text Available Mammalian bone has shown a variety of responses to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD exposure in experimental and wildlife studies. Although many responses have been well characterized in the postcranial skeleton, dioxin-induced effects on the cranium are largely unknown. In this study, we investigated the effects of chronic adult exposure to TCDD on cranial size and shape in dioxin-resistant Han/Wistar (H/W and dioxin-sensitive Long–Evans (L–E rat strains. Three-dimensional landmark configurations for the face, vault, and base of the cranium were recorded and analyzed using geometric morphometrics (GM and dose–response modeling. The strongest effects were shown by L–E and H/W rats with daily exposures of 100 and 1000 ng TCDD/kg bw/day, respectively, resulting in significant reductions in centroid size (CS in all three cranial modules for both strains except for the vault in H/W rats. Consistent with previous evidence of intraspecific variation in TCDD resistance, the benchmark doses (CEDs for cranial size reduction in L–E rats were roughly 10-fold lower than those for H/W rats. For both strains, the face showed the greatest size reduction from the highest doses of TCDD (i.e., 3.6 and 6.3% decreases in H/W and L–E rats, respectively, most likely related to dose-dependent reductions in limb bone size and body weight gain. However, intrinsic morphological differences between strains were also observed: although the control groups of H/W and L–E rats had vaults and bases of comparable size, the face was 6.4% larger in L–E rats. Thus, although H/W rats possess an altered aryl hydrocarbon receptor (AhR that appears to mediate and provides some resistance to TCDD exposure, their smaller reductions in facial size may also relate to strain-specific patterns of cranial development and growth. Future research will be aimed at understanding how ontogenetic factors may modulate toxic effects of prenatal and lactational exposure on

    Dermopristis cairae n. sp. (Monogenea: Microbothriidae) is described from the skin and possibly from the nasal fossae of the giant shovel-nosed ray Glaucostegus typus (Bennett). The new species is distinguished from D. paradoxus Kearn, Whittington & Evans-Gowing, 2010 by its larger size, body shape, lack of transverse ridges on the ventral surface and absence of a seminal receptacle. Extensive short gut branches lie dorsal to the testes and adjacent to the coiled region of the vas deferens and the oötype, possibly reflecting high metabolic demand in these areas. Denticles are present in the lining of the nasal fossae of G. typus, providing a firm substrate for the cement-based attachment of a microbothriid. However, confirmation that D. cairae inhabits the nasal fossae of G. typus is required.

    Severity and duration of renal injury produced by low levels of uranyl fluoride (UO2F2) were examined in the rat. Rats received multiple ip injections of UO2F2 (cumulative dose: 0.66 or 1.32 mg U/kg body wt). Renal injury was characterized histologically by cellular and tubular necrosis of pars recta of proximal tubule (S2 and S3), with less severe cellular injury to thick ascending limb of loop of Henle and collecting tubule. Injury was evident when renal uranium levels were between 0.7 and 1.4 micrograms U/g wet kidney and was most severe when renal uranium burden was between 3.4 and 5.6 micrograms U/g. Repair of injury was rapid, with complete restoration within 35 days after exposure. Associated with injury were abnormalities in renal function, including impaired tubular reabsorption, proteinuria, and enzymuria, which appeared temporally related, to variable degrees, to progression of renal injury. Thus, reversible renal injury occurs in the rat at levels of uranium in kidney below the present Nuclear Regulatory Commission standard of 3 micrograms U/g kidney for renal injury in humans

The question raised in all of the three most recent cases was whether or not a debtor's application for debt review in terms of the National Credit Act constitutes an "act of insolvency" in terms of section 8 of the Insolvency Act, upon which a creditor may rely in an application for the compulsory sequestration of the debtor's estate. If it does, it would mean that by resorting to the debt relief measures provided by the National Credit Act a debtor commits the very act on which a creditor may base an application for a sequestration order which, if granted, will render the debtor's estate insolvent and bring about the liquidation of his assets. From the debtor's perspective, this is probably precisely the situation that he seeks to avert by applying for debt review. Further, sequestration would frustrate the stated purpose of the National Credit Act, which is that debtors should take responsibility for their debts by satisfying them in full. Concurrent creditors might also ultimately receive a dividend which falls far short of what is due to them. The question of whether a debtor's resorting to debt review may or should be the very act that triggers his estate's sequestration and its attendant consequences is an important issue, the treatment of which impacts significantly on the efficacy of the South African consumer debt relief system.

    Full Text Available Today, armed forces are in continuous transformation. As new technologies are developed and new principles of war are introduced, the ministries of defenses and armed forces have to adapt to this changing environment. Almost every day, military officials start new projects to handle the technological and cultural transformations in the military. Project management became an integral part of defense development and management. Today, all high or middle level military officials are either a project sponsor overseeing a project, or a project manager executing a project, or a member of project team helping the project to become a reality. As a result, project management skills became an essential part of skillset that a military official need to successfully execute his/her duties.

  14. Contribution of ketone bodies to cholesterogenesis in Morris hepatoma 7777 cells

    International Nuclear Information System (INIS)

    Hilderbrandt, L.; Elson, C.; Shrago, E.

    1990-01-01

    Cholesterol synthesis in neoplastic tissues is typically measured in incubations of minced tissue or tissue slices with 10 mM concentrations of individual substrates. Carbon incorporation into cholesterol from [ 14 C] labelled substrates by freshly isolated hepatoma cells was measured after one hour incubation with 10 mm single substrates. These observations were extended by measuring cholesterol synthesis supported by [ 14 C] substrates in a media containing a mixture of substrates at physiological concentrations: 5.0 mM glucose, 1.3 mM D(-)-3-hydroxybutyrate, 0.5 mM acetoacetate, 0.3 mM acetate, 0.3 mM oleate, 0.3 mM palmitate, 0.65 mM glutamine, 1.4 mM lactate and 0.1 mM pyruvate in Eagle's modified essential medium. Under single substrate conditions, the ketone bodies contribute substantially to cholesterogenesis. Estimates of the quantitative contribution of each substrate to total cholesterol synthesis are reported

  15. Hydrogeology and simulation of ground-water flow, Picatinny Arsenal and vicinity, Morris County, New Jersey

    Science.gov (United States)

    Voronin, L.M.; Rice, D.E.

    1996-01-01

    Ground-water flow in glacial sediments and bedrock at Picatinny Arsenal, N.J., was simulated by use of a three-dimensional finite-difference ground- water-flow model. The modeled area includes a 4.3-square-mile area that extends from Picatinny Lake to the Rockaway River. Most of the study area is bounded by the natural hydrologic boundaries of the ground-water system. eophysical logs, lithologic logs, particle-size data, and core data from selected wells and surface geophysical data were analyzed to define the hydrogeologic framework. Hydrogeologic sections and thickness maps define six permeable and three low-permeability layers that are represented in the model as aquifers and confining units, respectively. Hydrologic data incorporated in the model include a rate of recharge from precipitation of 22 inches per year, estimated from long-term precipitation records and estimates of evapotranspiration. Additional recharge from infiltration along valleys was estimated from measured discharge of springs along the adjacent valley walls and from estimates of runoff from upland drainage that flows to the valley floor. Horizontal and vertical hydraulic conductivities of permeable and low-permeability layers were estimated from examination of aquifer-test data, gamma-ray logs, borehole cuttings, and previously published data. Horizontal hydraulic conductivities in glacial sediments range from 10 to 380 feet per day. Vertical hydraulic conductivities of the low-permeability layers range from 0.01 to 0.7 feet per day. The model was calibrated by simulating steady-state conditions during 1989-93 and by closely matching simulated and measured ground-water levels, vertical ground-water-head differences, and streamflow gain and loss. Simulated steady-state potentiometric- surface maps produced for the six permeable layers indicate that ground water in the unconfined material within Picatinny Arsenal flows predominantly toward the center of the valley, where it discharges to Green Pond Brook. Beneath the upper confining unit, ground water flows southwestward, down the valley. Between First Street and Farley Avenue, the upper confining unit pinches out near the valley walls, resulting in a major input of water to, and causing a local potentiometric high in, the underlying aquifer layers. Ground-water-flow directions southwest of the southern arsenal boundary are predominantly to the Rockaway River.

    2017-10-01

    The main purposes of this paper are to accomplish the existence, stability, instability and bifurcation of the nonlinear waves of the nonlinear system of reaction diffusion equations ut =uxx + α [ βH (u - θ) - u ] - w, wt = ε (u - γw) and to establish the existence, stability, instability and bifurcation of the nonlinear waves of the nonlinear scalar reaction diffusion equation ut =uxx + α [ βH (u - θ) - u ], under different conditions on the model constants. To establish the bifurcation for the system, we will study the existence and instability of a standing pulse solution if 0 1; the existence and instability of two standing wave fronts if 2 (1 + αγ) θ = αβγ and 0 traveling wave front as well as the existence and instability of a standing pulse solution if 0 traveling wave front as well as the existence and instability of an upside down standing pulse solution if 0 traveling wave back of the nonlinear scalar reaction diffusion equation ut =uxx + α [ βH (u - θ) - u ] -w0, where w0 = α (β - 2 θ) > 0 is a positive constant, if 0 motivation to study the existence, stability, instability and bifurcations of the nonlinear waves is to study the existence and stability/instability of infinitely many fast/slow multiple traveling pulse solutions of the nonlinear system of reaction diffusion equations. The existence and stability of infinitely many fast multiple traveling pulse solutions are of great interests in mathematical neuroscience.

  7. A redetermination of the Barnes-Evans relation for surface flux in the V band

    International Nuclear Information System (INIS)

    Eaton, J.A.; Poe, C.H.

    1984-01-01

    Paying especial attention to the errors, we have redetermined the relation between visual flux at the star and color for stars with measured angular diameters. For stars cooler than the sun this is given both as a group of four polynomials in (V-R) for various parts of the range (V-R) >or approx.0.2, which start to recognize the fine structure in the flux-color relation, and as a straight line fitted to the data for 0,7 ≤ (V-R) ≤ 2.5. For stars hotter than the sun we give a table of surface flux vs. spectral type and (B-I) color. For stars later than the sun this flux-color relation is still defined almost entirely by giants. The conclusion that visual surface flux is a single function of (V-R) for all luminosity classes remains weak because of the small number of dwarfs and supergiants with angular diameters, likely systematic errors in the angular diameters of supergiants and the relatively large errors of individual angular diameters. The flux-color relation is combined with independent scales of bolometric corrections to give effective temperatures. We find that our results agree moderately well with those of Code et al. (1976), on which they are primarily based, for the hotter stars. However, they imply significant revisions of both the temperature and bolometric-correction scales for cool stars. 94 refs., 5 figs., 4 tabs. (author)

    1982-03-01

    During genetic selection of rats for high and low levels of red cell 2,3-diphosphoglycerate (DPG) the decreased fertility in Low-DPG animals was due to significantly (P less than 0.01) fewer offspring born per litter. The rat lines were intercrossed and animals at the tails of the F2 2,3-diphosphoglycerate distribution were mated. Subsequent matings of F3 offspring were monitored. Low-DPG F3 pregnant females killed at 20 days of gestation showed significantly (P less than 0.05) fewer corpora lutea than High-DPG F3 females. There were also significantly (P less than 0.01) fewer corpora lutea in Low-DPG line rats compared to High-DPG rats. It is concluded that the relationship between 2,3-diphosphoglycerate levels and fertility is not due to inbreeding but to a possible genetic linkage, a shared biochemical determinant or a relationship through the effect of 2,3-diphosphoglycerate levels on oxygen delivery to tissue.

  18. The effects of nicotine on ethanol-induced conditioned taste aversions in Long-Evans rats.

    Overall drug acceptability is thought to be a function of the balance between its rewarding and aversive effects, the latter of which is reportedly affected by polydrug use. Given that nicotine and alcohol are commonly co-used, the present experiments sought to assess nicotine's impact on ethanol's aversive effects within a conditioned taste aversion design. Experiment 1 examined various doses of nicotine (0, 0.4, 0.8, 1.2 mg/kg) to determine a behaviorally active dose, and experiment 2 examined various doses of ethanol (0, 0.5, 1.0, 1.5 g/kg) to determine a dose that produced intermediate aversions. Experiment 3 then examined the aversive effects of nicotine (0.8 mg/kg) and ethanol (1.0 g/kg) alone and in combination. Additionally, nicotine's effects on blood alcohol concentrations (BAC) and ethanol-induced hypothermia were examined. Nicotine and ethanol combined produced aversions significantly greater than those produced by either drug alone or the summed aversive effects of the individual compounds. These effects were unrelated to changes in BAC, but nicotine and ethanol combined produced a prolonged hypothermic effect which may contribute to the increased aversions induced by the combination. These data demonstrate that nicotine may interact with ethanol, increasing ethanol's aversive effects. Although the rewarding effects of concurrently administered nicotine and ethanol were not assessed, these data do indicate that the reported high incidence of nicotine and ethanol co-use is unlikely due to reductions in the aversiveness of ethanol with concurrently administered nicotine. It is more likely attributable to nicotine-related changes in ethanol's rewarding effects.

    Most people consider that the starting point for the LHC was a meeting organised by the European Committee for Future Accelerators in Lausanne in March 1984, even though quite a few of us at CERN had already begun work on the design in 1981. Since that time this truly unique machine has moved from a dream to a reality. With its ‘two in one’ magnet structure cooled by superfluid helium for operation at 1.9 K, the LHC is like no other particle collider. In a very real sense, the LHC is its own prototype. Other colliders have either consisted of two rings to accelerate and store two beams of particles, as in the Intersecting Storage Rings (ISR) here at CERN, or they have stored particles and their antiparticles travelling in opposite directions with a single ring, as we did with the Large Electron-Positron (LEP) collider. In addition, the LHC is the first accelerator in which the superconducting magnets have been cooled as low as 1...

    2012-08-01

    Full Text Available Pyritized internal moulds of articulated shells of the Early Jurassic brachiopod taxon Nannirhynchia pygmaea were found in beds closely below the early Toarcian oceanic anoxic event in the Polymorphum Zone in Portugal. The material allows a detailed study of the outline of the muscle fields, the length and direction of the crura, and the orientation of the cardinalia, which are hitherto undescribed. Three-dimensional reconstructions of articulated shells of N. pygmaea occurring in a single horizon were produced to show the orientation and length of arcuiform crura. The preservation of internal moulds together with the three-dimensional reconstruction of the internal shell morphology allow a more precise description of the internal morphology of this taxon than it is possible with articulated shells and serial sections. doi:10.1002/mmng.201200005

  8. Sex difference in cue strategy in a modified version of the Morris water task: correlations between brain and behaviour.

    Directory of Open Access Journals (Sweden)

    Robin J Keeley

    Full Text Available BACKGROUND: Sex differences in spatial memory function have been reported with mixed results in the literature, with some studies showing male advantages and others showing no differences. When considering estrus cycle in females, results are mixed at to whether high or low circulating estradiol results in an advantage in spatial navigation tasks. Research involving humans and rodents has demonstrated males preferentially employ Euclidean strategies and utilize geometric cues in order to spatially navigate, whereas females employ landmark strategies and cues in order to spatially navigate. METHODOLOGY/PRINCIPAL FINDINGS: This study used the water-based snowcone maze in order to assess male and female preference for landmark or geometric cues, with specific emphasis placed on the effects of estrus cycle phase for female rat. Performance and preference for the geometric cue was examined in relation to total hippocampal and hippocampal subregions (CA1&2, CA3 and dentate gyrus volumes and entorhinal cortex thickness in order to determine the relation between strategy and spatial performance and brain area size. The study revealed that males outperformed females overall during training trials, relied on the geometric cue when the platform was moved and showed significant correlations between entorhinal cortex thickness and spatial memory performance. No gross differences in behavioural performance was observed within females when accounting for cyclicity, and only total hippocampal volume was correlated with performance during the learning trials. CONCLUSIONS/SIGNIFICANCE: This study demonstrates the sex-specific use of cues and brain areas in a spatial learning task.

    2012-09-01

    Full Text Available The pigmented rat is an increasingly important model in visual neuroscience research, yet the lamination of retinal projections in the dLGN has not been examined in sufficient detail. From previous studies it was known that most of the rat dLGN receives monocular input from the contralateral eye, with a small island receiving predominantly ipsilateral projections. Here we revisit the question using cholera toxin B subunit (CTB, a tracer that efficiently fills retinal terminals after intra-ocular injection. We imaged retinal termini throughout the dLGN at 0.5 um resolution and traced areas of ipsilateral and contralateral terminals to obtain a high resolution 3D reconstruction of the projection pattern. Retinal termini in the dLGN are well segregated by eye of origin, as expected. We find, however, that the ipsilateral projections form multiple discrete projection zones in three dimensions, not the single island previously described. It remains to be determined whether these subdomains represent distinct functional sublaminae, as is the case in other mammals.

    Conclusions: We have shown that DJB alone does not improve glucose tolerance in obese, diabetic OLETF rats. Therefore, it may be that DJB alone is insufficient for diabetic control in obese diabetic rats. The addition of a restrictive component such as sleeve gastrectomy, or a new drug may be necessary for achieving diabetes reversal.

    Despite recent advances in polar marine biology and related fields, many aspects of the ecological interactions that are crucial for the functioning of Antarctic shallow water habitats remain poorly understood. Although epiphytic diatoms play an essential role in the Antarctic marine food web, basic information regarding their ecology, biodiversity and biogeography is largely unavailable. Here, we synthesise studies on Ross Sea epiphytic diatoms collected during 11 summer Antarctic expeditions between the years 1989/90 and 2011/12, presenting a full list of diatom taxa associated with three macroalgal species (Iridaea cordata, Phyllophora antarctica, and Plocamium cartilagineum) and their epiphytic sessile fauna. Diatom communities found during the three summer months at various depths and sampling stations differed significantly in terms of species composition, growth form structure and abundances. Densities ranged from 21 to >8000 cells mm-2, and were significantly higher on the surface of epiphytic micro-fauna than on any of the macroalgal species examined. Generally, host organisms characterized by higher morphological heterogeneity (sessile microfauna, ramified Plocamium) supported richer diatom communities than those with more uniform surfaces (Iridaea). Differences between epiphytic communities associated with different macroalgae were reflected better in species composition than in growth form structure. The latter changed significantly with season, which was related strongly to the changing ice conditions. A general trend towards an increasing number of erect forms in deeper waters and tube-dwelling diatoms in the shallowest sites (2–5 m) was also observed. This study explores further important and largely previously unknown aspects of relationships and interactions between Antarctic epiphytic diatoms and their micro- and macro-environments.

    Tetranychus evansi (Te) is an exotic pest of solanaceous crops in Africa. The predatory mite Phytoseiulus longipes (Pl) and the fungus Metarhizium anisopliae (Ma), are potential biocontrol agents of Te. The present study investigated efficacy of fungus-treated foam placed above or below the third Te-infested tomato leaf. The persistence of fungus-treated foam and the performance of Pl with or without fungus-treated foam were evaluated. The fungus-treated foam was effective when Te infestation was below the third tomato leaf as no damage was recorded on all upper tomato leaves up to 30 days post-treatment. However, in the control treatments, the infestation increased considerably from 9±0.3% to 100±0% at 15 days post-treatment. The reuse of the fungus-treated foam at 15, 30 and 45 days post-treatment resulted in 19±1.4%, 25±1.2% and 54±2.1% respective infestation by Te. The fungus-treated foam and Pl alone are efficient, but there is no benefit to combinting both against Te. The fungus-treated foam is an effective method to optimize the use of Ma in screenhouse conditions. These two control agents could be integrated in an IPM strategy for crops protection. However, these results need to be confirmed in large field trials. This article is protected by copyright. All rights reserved. This article is protected by copyright. All rights reserved.

    Maternal docosahexaenoic acid (DHA, 22:6n-3) supplies the developing fetus during pregnancy; however, the mechanisms are unclear. We utilized pregnant rats to determine rates of DHA accretion, tissue unesterified DHA uptake and whole-body DHA synthesis-secretion. Female rats maintained on a DHA-free, 2% α-linolenic acid diet were either:1) sacrificed at 56 days for baseline measures, 2) mated and sacrificed at 14-18 days of pregnancy or 3) or sacrificed at 14-18 days as age-matched virgin controls. Maternal brain, adipose, liver and whole body fatty acid concentrations was determined for balance analysis, and kinetic modeling was used to determine brain and liver plasma unesterified DHA uptake and whole-body DHA synthesis-secretion rates. Total liver DHA was significantly higher in pregnant (95±5 μmol) versus non-pregnant (49±5) rats with no differences in whole-body DHA synthesis-secretion rates. However, liver uptake of plasma unesterified DHA was 3.8-fold higher in pregnant animals compared to non-pregnant controls, and periuterine adipose DHA was lower in pregnant (0.89±0.09 μmol/g) versus non-pregnant (1.26±0.06) rats. In conclusion, higher liver DHA accretion during pregnancy appears to be driven by higher unesterified DHA uptake, potentially via DHA mobilization from periuterine adipose for delivery to the fetus during the brain growth spurt.

    2014-11-01

    Adolescent social instability stress (SS; daily 1 hr isolation + new cage partners postnatal days 30-45; thereafter with original cage partner, also in the SS condition) and control (CTL) rats competed for access to a preferred food in five sessions against their cage partner. In the first session, SS pairs displayed more aggression (face whacks, p = .02; rear attacks, p = .03), were less likely to relinquish access to the food voluntarily (p = .03), spent more time at the feeder than CTL pairs (p = .06), but did not differ in latency to access the feeder (p = .41). Pairs were considered in dominant-submissive relationships (DSR) if one rat spent significantly more time at the feeder than the other; 8 of 12 SS and 8 of 12 CTL pairs displayed DSRs (remaining: no-DSR). Aggression increased from the 1st to 5th session (p food reward. These results add to evidence that SS in adolescence modifies the adult social repertoire of rats and highlight the importance of adolescent social experiences for adult behavior. © 2014 Wiley Periodicals, Inc.

    European efforts to 'mainstream' the notion of Responsible Research and Innovation (RRI) is challenged by a lack of organisational and individual incentives, but also by absense of relevant measures of RRI. The European Commission has launched a study with the aim of developing indicators capturing the evolution and benefits of RRI across Europe. This paper presents the preliminary set of indicators identified by the project consortium. In recent years, the notion of Responsible Research and Innovation (RRI) has emerged in European policy making. From the perspective of the ‘Science with and for Society’ (SwafS) scheme of the European Commission (EC), the purpose of promoting RRI is “to build effective cooperation between science and society, to recruit new talent for science and to pair scientific excellence with social awareness and responsibility” (EC, 2016).

  6. The University of Minnesota Morris - N.S.F. REU Program: Twenty years of encouraging women to participate in the Geological Sciences

    Science.gov (United States)

    Cotter, J. F.

    The goal of the UMM - REU program is to nurture the development of women in the geological sciences. Women are historically under-represented in the geological sciences. This program introduces undergraduate women to research project design and independent data collection and analysis designed to increase student’s scientific skills, introduce them to new fields of study, and to develop academic/professional confidence. In so doing, the program tries to encourage students to continue their education at the graduate level and/or to pursue a career in the Geosciences. The program was first proposed in 1988 and was run during the summers of 1989, '90, '91, '94, '95, '97, ’99, 2000, 05, 07, and 09 (in 1996 and 1998 a similar program was run at Gustavus Adolphus College). The focus of the program is field and laboratory research to determine the origin and history of glacial deposits in west-central Minnesota and the late Paleozoic Glacial deposits of the Parana Basin, Brazil. Much of the success of the program can be attributed to developing student “ownership” of their individual projects, their particular REU group, and the UMM-REU program overall. Research projects are selected and designed by the participants. Frequently considered are: research subject, location of field area and geologic techniques employed. Both project ownership and team building is encouraged by participant led weekly visits to field areas and frequent group discussions of research problems, successes and major gaffes. Additional team building activities include: 1) living in the same on-campus apartments and Brazilian B&B, 2) organized social activities, 3) international travel and working with Brazilian (women) students, 4) readings and discussions on "women in geology”, 5) shared strategies and concerns for career choices and; 6) participation in the "Friends of UMM-REU" conference (an "informal" presentation of results). Finally, an emphasis is placed on the utilization of the support network that has developed among the UMM-REU alumni. Participants read publications by past UMM-REU researchers, they are encouraged to contact alumni for information and advice, and alumni are invited back to mentor participants, provide insights and interact socially. UMM-REU reunions are held on a regular basis. The UMM-REU network is growing. Ninety-three women from 30 institutions have participated in the UMM-REU program. Participants have published four papers and 75 abstracts. Initial career trajectories are good. Of the 80 UMM-REU alumni that have (to date) received a bachelor degree: 29 went directly into careers in the sciences or teaching and 46 enrolled in graduate (9 have completed Ph.D.s). Over the long term results are also good. Of the 93 UMM-REU participants only 13 are not now pursuing degrees or working in careers in the sciences. Research for this study was funded by a grant from the N.S.F.-R.E.U. Program, including NSF-EAR 9820249 and NSF-EAR 0640575.

    Full Text Available This essay analyzes one of the main arguments put forward by the tobacco industry to support the absence of liability for damages caused by tobacco addiction: the free will of the smoker. Through the contribution of other sciences, it seeks to demonstrate how young people, targeted audience of marketing campaigns of the tobacco industry, were extremely vulnerable to tobacco industry maneuvers to attract them to their products. It also demonstrates the addictive effects of nicotine and how it practically neutralizes the ability of an adult deciding to stop the addiction. At the end, it sustains the relativization of the principle of free will.

    The authors comment that Hopewell et al (1987) found a much greater field-size dependence for the dose-response curves for white matter necrosis than for vascular lesions. The results for white matter necrosis are not well described by the authors' own model. It is suggested that the treatment of the spinal cord as a one-dimensional organ may be appropriate for vascular lesions, because of the organization of the microvasculature, but it may be an unacceptable oversimplification for white matter necrosis. For such lesions, it may be necessary to treat the spinal cord as a three-dimensional cylinder and consider repair by lateral as well as axial migration of stem cells. (author)

    Maternal delivery of docosahexaenoic acid (DHA, 22:6n-3) to the developing fetus via the placenta is required for fetal neurodevelopment, and is the only mechanism by which DHA can be accreted in the fetus. The aim of the current study was to utilize a balance model of DHA accretion combined with kinetic measures of serum unesterified DHA uptake to better understand the mechanism by which maternal DHA is delivered to the fetus via the placenta. Female rats maintained on a 2% α-linolenic acid diet free of DHA for 56 days were mated, and for balance analysis, sacrificed at 18 days of pregnancy, and fetus, placenta and maternal carcass fatty acid concentration were determined. For tissue DHA uptake, pregnant dams (14-18 days) were infused for 5 min with radiolabeled 14 C-DHA and kinetic modeling was used to determine fetal and placental serum unesterified DHA uptake rates. DHA accretion rates in the fetus were determined to be 38 ± 2 nmol/d/g, 859 ± 100 nmol/d/litter and 74 ± 3 nmol/d/pup, which are all higher (P  0.05) in placental DHA accretion rates versus serum unesterified DHA uptake rates were observed as values varied only 6-35% between studies. No differences in placental accretion and uptake rates suggests that serum unesterified DHA is a significant pool for the maternal-placental transfer of DHA, and lower fetal DHA uptake compared to accretion supports remodeling of placental DHA for delivery to the fetus.

    A hallmark of long-term memory formation is the requirement for protein synthesis. Administration of protein synthesis inhibitors impairs long-term memory formation without influencing short-term memory. Rapamycin is a specific inhibitor of target of rapamycin complex 1 (TORC1) that has been shown to block protein synthesis and impair long-term memory. In addition to regulating protein synthesis, TORC1 also phosphorylates Unc-51-like autophagy activating kinase-1 (Ulk-1) to suppress autophagy. As autophagy can be activated by rapamycin (and rapamycin inhibits long-term memory), our aim was to test the hypothesis that autophagy inhibitors would enhance long-term memory. To examine if learning alters autophagosome number, we used male reporter mice carrying the GFP-LC3 transgene. Using these mice, we observed that training in the Morris water maze task increases the number of autophagosomes, a finding contrary to our expectations. For learning and memory studies, male Long Evans rats were used due to their relatively larger size (compared to mice), making it easier to perform intrahippocampal infusions in awake, moving animals. When the autophagy inhibitors 3-methyladenine (3-MA) or Spautin-1 were administered bilaterally into the hippocampii prior to training in the Morris water maze task, the drugs did not alter learning. In contrast, when memory was tested 24 hours later by a probe trial, significant impairments were observed. In addition, intrahippocampal infusion of an autophagy activator peptide (TAT-Beclin-1) improved long-term memory. These results indicate that autophagy is not necessary for learning, but is required for long-term memory formation. © 2017 Wiley Periodicals, Inc.

    2013-10-01

    Male Long-Evans rats were given injections of either 192 IgG-saporin, an apparently selective toxin for basal forebrain cholinergic neurons (LES), or vehicle (CON) into either the medial septum and vertical limb of the diagonal band (MS/VDB) or bilaterally into the nucleus basalis magnocellularis and substantia innominata (nBM/SI). Place discrimination in the Morris water maze assessed spatial learning, and a trial-unique matching-to-place task in the water maze assessed memory for place information over varying delays. MS/VDB-LES and nBM/SI-LES rats were not impaired relative to CON rats in acquisition of the place discrimination, but were mildly impaired relative to CON rats in performance of the memory task even at the shortest delay, suggesting a nonmnemonic deficit. These results contrast with effects of less selective lesions, which have been taken to support a role for basal forebrain cholinergic neurons in learning and memory. 2013 APA, all rights reserved

    Radiation encephalopathy is the main complication of cranial radiotherapy. It can cause necrosis of brain tissue and cognitive dysfunction, to which no ideal prevention method is available until now. Hydroxysaffor yellow A (HSYA) is the main active ingredient of the traditional Chinese medicine safflower, with protective effects against cerebral ischemic injury. In this work, we investigated the protective effects of HSYA on brain injury in mice irradiated by 300 MeV/u 12 C 6+ ion beam. The whole head of male Kunming mouse was irradiated to 4.0 Gy after receiving daily intra-peritoneal injection HSYA for 3 d. One month later, the Morris water maze test was used to detect the spatial memory in mice. The Evans blue was used as the tracer to evaluate the permeability of blood-brain barrier. The SOD activity and MDA content in brain tissue were assayed by test kits. The results showed that the 12 C 6+ irradiation significantly impaired the spatial learning and memory in mice, increased the permeability of blood-brain barrier and the MDA content in brain tissue, whereas decreased the SOD activity in brain tissue. The pretreatment with HSYA could improve the spatial memory deficits and inhibit the changes of the blood-brain barrier, the SOD activity and the MDA content in brain tissue in mice. All these demonstrate that HSYA possesses the protective effect against brain injury induced by 12 C 6+ particle therapy. (authors)

  5. Opening of the blood-brain barrier before cerebral pathology in mild hyperhomocysteinemia.

    Full Text Available Hyperhomocysteinemia (HHcy is a risk factor for cognitive impairment. The purpose of this study was to determine the temporal pattern of cerebral pathology in a mouse model of mild HHcy, because understanding this time course provides the basis for understanding the mechanisms involved. C57Bl/6 mice with heterozygous deletion cystathionine β-synthase (cbs (+/-; Het were used as a model of mild HHcy along with their wild-type littermates (cbs (+/+; WT. Mice were 'young' (5.3±0.2 months of age and 'old' (16.6±0.9 months of age. Blood-brain barrier (BBB permeability was quantified from Evans blue and sodium fluorescein extravasation. Microvascular architecture was assessed by z-stack confocal microscopy. Leukoaraiosis was measured from Luxol fast blue stained slides of paraffin brain sections. Inflammation was quantified using standard antibody-based immunohistochemical techniques. Cognitive function was assessed using the Morris water maze. BBB permeability was significantly greater in Het vs. WT mice at all ages (p<0.05. There were no differences in microvascular architecture among the groups. Compared with all other groups, old Het mice had significantly greater leukoaraiosis, inflammation in the fornix, and cognitive impairment (p<0.05. In mild HHcy, increased permeability of the BBB precedes the onset of cerebral pathology. This new paradigm may play a role in the progression of disease in HHcy.

    Experience-dependent plasticity is an ongoing process that can be observed and measured at multiple levels. The first goal of this study was to examine the effects of prenatal nicotine on the performance of rats in three behavioral tasks (elevated plus maze (EPM), Morris water task (MWT), and Whishaw tray reaching). The second goal of this experiment sought to examine changes in dendritic organization following exposure to the behavioral training paradigm and/or low doses of prenatal nicotine. Female Long-Evans rats were administered daily injections of nicotine for the duration of pregnancy and their pups underwent a regimen of behavioral training in early adulthood (EPM, MWT, and Whishaw tray reaching). All offspring exposed to nicotine prenatally exhibited substantial increases in anxiety. Male offspring also showed increased efficiency in the Whishaw tray-reaching task and performed differently than the other groups in the probe trial of the MWT. Using Golgi-Cox staining we examined the dendritic organization of the medial and orbital prefrontal cortex as well as the nucleus accumbens. Participation in the behavioral training paradigm was associated with dramatic reorganization of dendritic morphology and spine density in all brain regions examined. Although both treatments (behavior training and prenatal nicotine exposure) markedly altered dendritic organization, the effects of the behavioral experience were much larger than those of the prenatal drug exposure, and in some cases interacted with the drug effects.

    Web-based interventions present a potentially cost-effective approach to supporting self-management for cancer patients; however, further evidence for acceptability and effectiveness is needed. The goal of our research was to assess the effectiveness of an individualized Web-based cognitive behavioral therapy (CBT) intervention on improving psychological and quality of life outcomes in cancer patients with elevated psychological distress. A total of 163 distressed cancer patients (111 female, 68.1%) were recruited through the Queensland Cancer Registry and the Cancer Council Queensland Cancer Helpline and randomly assigned to either a Web-based tailored CBT intervention (CancerCope) (79/163) or a static patient education website (84/163). At baseline and 8-week follow-up we assessed primary outcomes of psychological and cancer-specific distress and unmet psychological supportive care needs and secondary outcomes of positive adjustment and quality of life. Intention-to-treat analyses showed no evidence of a statistically significant intervention effect on primary or secondary outcomes. However, per-protocol analyses found a greater decrease for the CancerCope group in psychological distress (P=.04), cancer-specific distress (P=.02), and unmet psychological care needs (P=.03) from baseline to 8 weeks compared with the patient education group. Younger patients were more likely to complete the CancerCope intervention. This online CBT intervention was associated with greater decreases in distress for those patients who more closely adhered to the program. Given the low costs and high accessibility of this intervention approach, even if only effective for subgroups of patients, the potential impact may be substantial.

  8. Distribution and levels of [125I]IGF-I, [125I]IGF-II and [125I]insulin receptor binding sites in the hippocampus of aged memory-unimpaired and -impaired rats

    The insulin-like growth factors (IGF-I and IGF-II) and insulin are localized within distinct brain regions and their respective functions are mediated by specific membrane receptors. High densities of binding sites for these growth factors are discretely and differentially distributed throughout the brain, with prominent levels localized to the hippocampal formation. IGFs and insulin, in addition to their growth promoting actions, are considered to play important roles in the development and maintenance of normal cell functions throughout life. We compared the anatomical distribution and levels of IGF and insulin receptors in young (five month) and aged (25 month) memory-impaired and memory-unimpaired male Long-Evans rats as determined in the Morris water maze task in order to determine if alterations in IGF and insulin activity may be related to the emergence of cognitive deficits in the aged memory-impaired rat. In the hippocampus, [ 125 I]IGF-I receptors are concentrated primarily in the dentate gyrus (DG) and the CA3 sub-field while high amounts of [ 125 I]IGF-II binding sites are localized to the pyramidal cell layer, and the granular cell layer of the DG. [ 125 I]insulin binding sites are mostly found in the molecular layer of the DG and the CA1 sub-field. No significant differences were found in [ 125 I]IGF-I, [ 125 I]IGF-II or [ 125 I]insulin binding levels in any regions or laminae of the hippocampus of young vs aged rats, and deficits in cognitive performance did not relate to altered levels of these receptors in aged memory-impaired vs aged memory-unimpaired rats. Other regions, including various cortical areas, were also examined and failed to reveal any significant differences between the three groups studied.It thus appears that IGF-I, IGF-II and insulin receptor sites are not markedly altered during the normal ageing process in the Long-Evans rat, in spite of significant learning deficits in a sub-group (memory-impaired) of aged animals.

  11. Spatial learning, monoamines and oxidative stress in rats exposed to 900 MHz electromagnetic field in combination with iron overload.

    The increasing use of mobile phone technology over the last decade raises concerns about the impact of high frequency electromagnetic fields (EMF) on health. More recently, a link between EMF, iron overload in the brain and neurodegenerative disorders including Parkinson's and Alzheimer's diseases has been suggested. Co-exposure to EMF and brain iron overload may have a greater impact on brain tissues and cognitive processes than each treatment by itself. To examine this hypothesis, Long-Evans rats submitted to 900 MHz exposure or combined 900 MHz EMF and iron overload treatments were tested in various spatial learning tasks (navigation task in the Morris water maze, working memory task in the radial-arm maze, and object exploration task involving spatial and non spatial processing). Biogenic monoamines and metabolites (dopamine, serotonin) and oxidative stress were measured. Rats exposed to EMF were impaired in the object exploration task but not in the navigation and working memory tasks. They also showed alterations of monoamine content in several brain areas but mainly in the hippocampus. Rats that received combined treatment did not show greater behavioral and neurochemical deficits than EMF-exposed rats. None of the two treatments produced global oxidative stress. These results show that there is an impact of EMF on the brain and cognitive processes but this impact is revealed only in a task exploiting spontaneous exploratory activity. In contrast, there are no synergistic effects between EMF and a high content of iron in the brain. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Objective – To examine the role of public libraries in the provision of adult literacy services, with a detailed look at both the successes and concerns of the libraries under study; to provide recommendations for best practice in establishing or reviewing adult literacy services. Design – A series of case studies using written reports and semi-structured interviews. Setting – Eight public libraries in the UK involved in literacy service provision or reader development services. Subjects – Eight senior staff members in charge of library literacy programming. Method – A written report of literacy service initiatives was solicited from each participating library. A single interview was conducted with a staff member in charge of literacy service at each of the eight participating libraries. Fact-checking telephone interviews were conducted at three locations where adult literacy programs were in early stages. More indepth, face-to-face interviews were conducted at the five libraries with better established programs. Each type of interview consisted of a set of scripted questions supplemented by individualized questions based on the written reports. Main results – There are four key areas of results to be summarized from this study: • Adult Literacy Collections – The authors observed three main approaches to branding literacy collections: − Emphasis on reading for pleasure (with collections entitled ‘Quick Reads’ or ‘First Choice’; − Emphasis on reading for skills development; − Discreet labelling enabling stock recognition without advertising that the reader is borrowing literacy materials. The authors conclude that the ‘Quick Reads’ approach was the most successful in highlighting the collection without stigmatizing it and in promoting the pleasure of reading. The importance of maintaining relevant, attractive books was highlighted, with collections targeting both entry level readers and emergent readers. • Approaches for Supporting Adult Literacy – The libraries used reader development extensively as a strategy to support adult literacy efforts. Staff tied literacy offerings to other programs or services of interest (for example, promoting adult literacy services alongside audiovisual collections and Internet access. Adult learners were also targeted for library tours, reading groups, and assistance with book selection for the literacy collection. Some of the libraries hired new staff from outside the library profession, choosing candidates with prior experience in basic skills development or community work. • Methods of Attracting Adults with Poor Literacy ‐‐ Partnership was identified as a key strategy for the libraries studied. Partnerships were formed with numerous agencies, including the probationary service, a community centre (where the library’s ‘reader in residence’ was installed, a college, and a Peugeot factory. Networking with other literacy service providers and coalitions was also an important strategy, particularly as a way to increase the library’s profile as a literacy service provider. Perhaps the simplest strategy for attracting adults with poor literacy was to identify areas of the library districts where literacy skills were lowest and then to target literacy service to those regions. • Sustainability and Mainstreaming ‐‐ Early planning for sustainability was crucial. Incorporating funding for literacy staffing and collections into the core budget and annual library plan was also an important step. While some libraries hired new staff, and one library staffed the literacy project with volunteers, using existing staff for adult literacy work proved to be more efficient and sustainable. Instilling a sense of ownership in the project for both staff and users of the literacy services by involving them in the development and promotion of literacy service and collections was another strategy employed to ensure longevity of the service. Conclusions – The most successful form of library literacy service provision was found to be the reader development approach (promoting reading for enjoyment and building reading activities around existing interests. The libraries studied showed an understanding of the wide range of reading levels and interests among adult learners. Potential barriers for libraries in the provision of adult literacy service “include restrictive funding criteria, limited staff capacity, and a bidding culture that remains unsympathetic to public library circumstances” (44. The authors make five recommendations for best practices in adult literacy service provision: • Eclectic adult literacy collections: Collections should be fresh and appealing and should incorporate engaging non‐fiction. • Standardized criteria for adult literacy stock: Standardized criteria should be developed by a basic skills agency, preferably at a national level. • Equality for adult readers: Approach adult readers as people who read for enjoyment or who are ‘getting back to reading’, rather than as those needing to ‘improve’ their reading. • Maximum access: Ensure a diverse and well‐stocked collection of books that is easy for adult learners to locate. • Community profiling: Optimize service delivery by profiling your community’s literacy levels.

  8. Revision of the Dysmorphoptilidae (Hemiptera: Cicadomorpha: Prosboloidea) of the Queensland Triassic-Part 2.

    2016-03-15

    The extinct hemipteran family Dysmorphoptilidae was a major component of the Triassic insect fauna of Queensland preserved at the Denmark Hill, Dinmore, Mount Crosby and Gayndah fossil insect sites. A total of 13 species have now been identified, of which eight species in five genera were examined in the first part of this revision. This second part revises the remaining five species in three genera. Eoscartoides Evans, 1956 (= Mesonirvana Evans, 1956, syn. nov.), comprising Eoscartoides bryani Evans, 1956 (= Mesonirvana abrupta Evans, 1956, syn. nov.) (Mount Crosby), Eoscartoides orthocladus (Tillyard, 1922) comb. nov. (Denmark Hill), and Eoscartoides dmitryi sp. nov. (Dinmore), is distinguished by a strongly developed arc-like strigil in the basal costal space, a very short stem of RA, and a deeply forked M1+2. The monotypic Eoscarterella Evans, 1956, with type species Eoscarterella media Evans, 1956 (Mount Crosby), has a strongly lobate tegmen with peculiar surface sculpture and M1+2 simple. Eoscartoides and Eoscarterella differ from most dysmorphoptilids in having more or less lobate tegmina with even margins (without the antero-apical emargination so typical of the family), as well as the early entry of RA1 into the costal margin and the associated extensive and antero-apically positioned RA2. These characters are also shared with two other dysmorphoptilids, the Australian Permian Belmontocarta Evans and an unnamed Triassic species from Kyrgyzstan, and the four thus form a distinct subgroup within the family. On the other hand, the monotypic Trifidella Evans, 1956 (= Alotrifidus Evans, 1956, syn. nov.), with type species Trifidella perfecta Evans, 1956 (= Alotrifidus interruptus Evans, 1956, syn. nov.) (Mount Crosby), is a more typical dysmorphoptilid with a distinct emargination, RA entering the margin much more apically, and RA2 of limited extent. Trifidella is presumably the sister of the Queensland Triassic Dysmorphoptiloides Evans, sharing the basal

    Full Text Available Objective - To assess e-book delivery on handheld devices provided to public library patrons, particularly housebound or visually impaired patrons and the users of a mobile library. Design - Product trial with a post-trial questionnaire for patrons and a post-trial focus group discussion among participating library staff. Setting - Mid-to-large size public library system in the United Kingdom. Subjects - 23 patrons participated; the number of library staff participating is not identified. Although the target population initially identified was housebound people, patrons reliant on the mobile library, and visually impaired people, the project team determined that it did not have sufficient funds to upgrade the PDAs to be compatible woth their preferred software for the visually impaired, and therefore this group was eliminated from the study. Lack of funds was also cited as a factor in the team being unable to provide assistive technology for those users suffering from arthritis, though this group was not excluded from the study. Just over half the patrons were aged 60+, and more than half were female. Two patrons self-identified as housebound. Methods - e-books were downloaded onto Hewlett Packard iPAQ 1910 Pdas by library staff and were loaned to participants between Janualry and April 2004. Although the authors of the study state that "creating staff champions was an important objective in this project" (p.176, it is unclear whether staff were screened for positive attitude towards e-Books. Prior to the trial, staff members were provided with training and orientation, and participants were asked for their font sna d reading preferences. Suport for participating patrons was available from staff or via an accompanying user manual, e-mail, or telephone help line. In a questionnaire adminsitered following the trial, participants were asked to respond to questions on the functionality of the handheld devices and e-book formats, positive and negative reactions to reading from the devices, and differences in the reading experience using the PDA as oopsed to a book. A group discussion with p[articipating library staff was held in April of 2004. The feedback from both groups was compared. Main results - Patrons: The devices were generally found to be usable, with a few exceptions; one patron with arthritis had difficulty operating the device and another developed hand cramps. Positive reactions regarding the vovelty of using the devices, portability (the ability to store several books on one small device and readability (the ability to customize font size and to read in low light conditions were offset by frustration with low battery life, small screen size, limits on usage (i.e. not to be used in the bath, difficulty paging back and forth ('getting lost on the iPAQ', and the inferior sensation of using a PDA as opposed to the 'tactile' quantity of books. In addtion, some patrons voiced fears that e-books might supplant paper books and libraries themselves. In all, thirteen patrons indicated that the e-books had some advantages over books, while eighteen found that there were aspects of using e-books that they disliked compared to books. Staff: The staff shared some concerns with the users, identifying portability as a strength and low battery life (including the need to reformat devices after batteries ran out as a weakness. In addition, some staff felt that some patrons preferred e-book format for books on sensitive topcs, as they provided more privacy in borrowing. Other staff concerns included the potential for users loading other software on the devices and the (presumably in the case of a full roll-out where users would download their own e-books from home lack of a broadband connection for some users. Conclusions - This study should be read as a case study of a trial of the Adobe Book and Palm e-book formats in Hewlett Packard iPAQ 1910 Pdas amongst a small group pf public library (primarily mobile library patrons. While the findings generally indicated that both staff and users found the technology tooo problematic to be adopted, the trial was confined to hardware and software specified. Furthermore, since the sample surveyed was small and not randomly selected, it would be difficult to apply the study's findings to the larger population (exact number not specified in the study of housebound and mobile library users of the Essex County system. For those who are considering the introduction of similar technology in a public library setting, the final report on the larger project of which this study was a part is available on the British Library website: http://www.bl.uk/about/cooperation/laser-pubs.html

  16. Obituary: Ronald Eugene Pitts, 1949-2008

    Science.gov (United States)

    MacConnell, D. Jack

    2009-01-01

    Ronald Pitts, systems engineer in the Commanding Branch of the Space Telescope Science Institute and long-time Computer Sciences Corporation employee, died suddenly of a stroke on 4 May 2008 at his home in Laurel, Maryland. He was a dedicated scientist-engineer, husband, father, volunteer, and cherished friend to many. Ron was born on 19 January 1949 in Tucson, Arizona, and was raised, along with his sister Suzanne, on his parents' turkey farm outside Tucson. He picked up practical knowledge from his father, Vernon, and became a competent amateur electrician and plumber, skills he kept honed and used throughout his life. His mother, Ruth (Stephens), was a nurse and taught him compassion and patience and encouraged his inquisitive mind. Ron attended public schools and enrolled at the University of Arizona, graduating with a B. S. in Astronomy in 1971. Being from a family of modest means, he put himself through school working summers and part-time at a large copper mine south of town. Ron enrolled in the graduate astronomy program at the Ohio State University [OSU] in the fall of 1971 where he was a first-year fellowship student. During his second and third years, he was the Perkins Assistant, taking spectra for the very exacting but appreciative Philip Keenan who once remarked to another faculty member that Ron was the best observer he ever had. Later, in 1980, Ron was co-author with Keenan on "Revised MK Spectral Types for G, K, and M stars" and again in 1985 in a study of supergiants in open clusters. He met his future wife, Patricia Moore, also a graduate student in the department, and they were wed in 1973. Ron was also partially supported during his early OSU years by an NSF grant to Robert Wing, writing parts of Wing's photometric reduction code and observing on the program at Kitt Peak and Flagstaff in the summer of 1974. Wing remembers him as being very competent and pleasant to work with. Ron's thesis topic was "Oscillator Strengths for Neutral Iron and

    Full Text Available Previous studies have shown that physical activity improves learning and memory. Present study was performed to determine the effects of acute, chronic and continuous exercise with different periods on spatial learning and memory recorded as the latency and length of swim path in the Morris water maze testing in subsequent 8 days. Four rat groups were included as follows: 1- Group C (controls which did not exercise. 2- Group A (30 days treadmill running before and 8 days during the Morris water maze testing period. 3- Group B (30 days exercise before the Morris water maze testing period only and 4- Group D (8 days exercise only during the Morris water maze testing period. The results showed that chronic (30 days and continuous (during 8 days of Morris water maze testing days treadmill training produced a significant enhancement in spatial learning and memory which was indicated by decreases in path length and latency to reach the platform in the Morris water maze test (p < 0.05. The benefits in these tests were lost in three days, if the daily running session was abandoned. In group D with acute treadmill running (8 days exercise only the difference between the Group A disappeared in one week and benefit seemed to be obtained in comparison with the controls without running program. In conclusion the chronic and daily running exercises promoted learning and memory in Morris water maze, but the benefits were lost in few days without daily running sessions in adult rats
