    Full Text Available Six adult horses were experimentally infected with Trypanosoma evansi (106 parasites. Three other adult horses served as negative control. Serum samples of the experimentally infected horses with T. evansi and non-infected controls horses were obtained before inoculation, and daily thereafter until 14 days post infection (DPI. After that time the serum samples were obtained weekly. Sera of the infected and non-infected control horses was tested by indirect fluorescent antibody test (IFAT and enzyme-linked immunosorbent assay (ELISA for the detection of antibodies against T. evansi. Both ELISA and IFAT detected trypanosomal antibodies shortly after infection and showed progressive increases in antibodies levels during early stages of infection. The responses started on the eighth and eleventh DPI. Maximum IFAT and ELISA values were reached after four weeks of infection and were maintained at this level until the end of the period of study.Seis eqüinos foram inoculados com 106 tripomastigota sangüícolas de Trypanosoma evansi. Três outros animais foram mantidos como testemunhas. Amostras de soro sangüíneo foram obtidas de todos os animais, antes da inoculação, e diariamente até o 14º dia pós inoculação (DPI; após este período uma vez por semana. Pesquisa de anticorpos anti- T. evansi, foram realizadas através da reação de imunofluorescência indireta (RIFI e do ensaio de imunoabsorção enzimática (ELISA. A resposta imune humoral, detectada através da RIFI e do ELISA, iniciou-se, em média, a partir do oitavo DPI, alcançando títulos máximos após quatro semanas de evolução, e os titulos de anticorpos anti- T. evansi mantiveram-se elevadas até o término das observações.

    Full Text Available As micoses superficiais são prevalentes em todo o mundo, geralmente ocasionadas por dermatófitos e restritas à camada córnea. A resposta imunológica do hospedeiro às infecções dos fungos dermatófitos depende basicamente das defesas do hospedeiro a metabólitos do fungo, da virulência da cepa ou da espécie infectante e da localização anatômica da infecção. Serão revistos alguns dos fatores da defesa imunológica do hospedeiro que influenciam na eficácia da resposta imune. Em especial, a participação dos receptores de padrão de reconhecimento (PRRs, tais como os receptores toll-like ou os da família lectina (DC-SIGN e dectin-2, que participam da resposta imune inata, conferindo-lhe especificidade e definindo o padrão da resposta imune como um todo. O predomínio celular ou humoral da resposta imune definirá o quadro clínico e o prognóstico da infecção, levando à cura ou cronicidadeSuperficial mycoses are prevalent worldwide. They are often caused by dermatophytes and restricted to the stratum corneum. The host's immune response against infections caused by dermatophytes basically depends on the host's defense against metabolites of the fungi, virulence of the infecting strain or species and anatomical site of the infection. We will review some of the factors of the host's immune defense that influence the efficacy of the immune response. We will particularly review the role of pattern recognition receptors (PRRs, such as toll-like receptors or lectin receptors (DCSIGN and Dectin 2, which participate in the innate immune response, bringing specificity to the immune response and setting its pattern. The predominance of a cellular or humoral immune response determines the clinical manifestations and the prognosis of the infection, leading to healing or chronicity

    Full Text Available TgROP2 is an intracellular protein associated with rhoptries of Toxoplama gondii and an antigen component of a candidate vaccine for toxoplasmosis. The purpose of the present study was to evaluate the efficacy of rTgROP2 to stimulate humoral and cellular immune responses in BALB/c mice via intranasal injection. TgROP2 partial coding sequence was (196-561 amplified by PCR from genomic T. gondii RH strain DNA and cloned into the pTrcHis expression vector. Escherichia coli Rosetta 2 cells transformed with pTrcHis-TgROP2 showed high levels (~1 mg.mL-1 of recombinant protein after 4 hours of IPTG induction. Recombinant TgROP2 exhibited an apparent Mr equal to 54 kDa. In order to test immunogenicity of the recombinant protein, 10 BALB/c mice received 10 µg of rROP2 protein + 10 µg of Quil-A via intranasal injection. Doses were administered at days 0, 21, and 42. Three animals were euthanized and used to evaluate cell-ular immune response on day 62. Five (50% and two (20% out of ten animals produced IgG (DO mean = 0.307; cut-off = 0.240 and IgA (DO mean = 0.133, cut-off = 0.101, respectively, by ELISA on day 62. The proliferation of splenocytes revealed high stimulation index (SI when co-cultured with 5, 10 and 15 µg.mL-1 of rTgROP2. These results indicate that intranasal immunization with recombinant protein ROP2 plus Quil-A can elicit both cellular and humoral immune responses in BALB/c mice.TgROP2 é uma proteína localizada nas roptrias do Toxoplasma gondii, sendo um antígeno candidato a componente de uma vacina contra a toxoplasmose.

    Full Text Available Despite the absence of current official reports showing the number of cattle infected by rabies, it is estimated that nearly 30,000 bovines are lost each year in Brazil. In order to minimize the important economic losses, control of the disease is achieved by eliminating bat colonies and by herd vaccination. In this study, we compare the antibody response in cattle elicited by vaccination with an attenuated ERA vaccine (AEvac and an inactivated-adjuvanted PV (IPVvac vaccine. The antibody titers were appraised by cell-culture neutralization test and ELISA, and the percentage of seropositivity was ascertained for a period of 180 days. IPVvac elicited complete seropositivity rates from day 30 to day 150, and even on day 180, 87% of the sera showed virus-neutralizing antibody titers (VNA higher than 0.5IU/ml. There were no significant differences between the VNA titers and seropositivity rates obtained with IPVvac in the two methods tested. AEvac, however, elicited significantly lower titers than those observed in the group receiving inactivated vaccine. In addition, the profiles of antirabies IgG antibodies, evaluated by ELISA, and VNA, appraised by cell-culture neutralization test, were slightly different, when both vaccines were compared.A raiva bovina, transmitida principalmente pelo morcego hematófago Desmodus rotundus, é endêmica em várias regiões do Brasil, com um crescente número de casos sendo registrados anualmente. O controle desta infecção em bovinos é feito pelo controle de colônias de morcegos hematófagos e pela vacinação dos rebanhos. Embora as vacinas inativadas sejam mais seguras e mais estáveis que as vacinas atenuadas, estas últimas são ainda amplamente utilizadas em muitas regiões do país, por se acreditar que confiram imunidade mais duradoura. Neste estudo, foram comparadas as respostas anticórpicas de dois grupos de bovinos imunizados com uma vacina atenuada e uma inativada disponíveis comercialmente. Os

    Full Text Available American visceral leishmaniasis (AVL is an important disease among children of northeast Brazil. In order to characterize antibody responses during AVL, sera of hospitalized patients were analyzed by ELISA and Western blot using a Leishmania chagasi antigen preparation. The ELISA was positive (asorbance [greater than or equals to] 0.196 at a serum dilution of 1:1024 in all patients at presentation, and fell to ward control levels over the following year. Only one of 72 control subjects tested positive, and that donor had a sibling with AVL. Immunoblots of the patients' sera recognized multiple bands, the most frequent of which were at approximately 116 kDa, 70 kDa, and 26 kDa. Less frenquently observed were bands at approximately 93 kDa, 74 kDa, 62 kDa, 46 kDa and 32 kDa. The ELISA responses and patterns of banding were distinctive for AVL, and could be used to differentiate patients with AVL from those with Chagas' disease of cutaneous leishmaniasis. Sera from six AVL patients followed for up to six weeks after treatment identified no new bands. Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE of surface iodinated parasite proteins showed one major band and four minor bands, whereas SDS-PAGE of biotinylated prarasite proteins revealed a banding pattern similar to those of patient sera. AVL appears to produce characteristic immunoblot patterns which can be used along with a sensitive screening ELISA to diagnose AVL.A leishmaniose visceral americana é uma doença importante entre crianças do nordeste do Brasil. Com o objetivo de caracterizar a resposta imune humoral durante o curso da doença, foram analisados soros de pacientes hospitalizados, pelos métodos ELISA e Western blot, usando-se preparaçöes de antígenos de Leishmania donovani chagasi.

    Full Text Available As larvas da Dermatobia hominis provocam lesões ulcerativas, danificando o tecido subcutâneo e conseqüentemente a pele do hospedeiro. O couro é o subproduto que sofre maior depreciação, o que, muitas vezes, impossibilita seu aproveitamento na industrialização. Atualmente o controle químico é utilizado como forma de combate à dermatobiose, entretanto, leva ao acúmulo de substâncias tóxicas nos animais e no ambiente. No presente trabalho, foram avaliadas as respostas imune-humoral e celular de bovinos imunizados com extrato antigênico preparado com larvas de D. hominis. Três grupos de oito bezerras da raça Nelore com 10 meses de idade foram usados, tendo o primeiro grupo (A recebido aplicação de extrato imunogênico de larvas de D. hominis, com intervalos de quinze dias; o grupo (B, utilizado como controle, não recebendo nenhum tipo de tratamento; e o grupo (C recebendo o tratamento ectoparasiticida à base de Dichlorvos associado a Cypermetrina. Neste mesmo período, foram avaliados o leucograma e os níveis de IgG contra D. hominis pela técnica de enzimoimunoensaio-ELISA. Quanto à avaliação da imunidade humoral, verificou-se que os animais do grupo A apresentaram maior produção de IgG contra D. hominis, com níveis máximos de anticorpos circulantes aos 45 dias após a primeira imunização. Estes animais também apresentaram maior produção de neutrófilos, eosinófilos e monócitos que os dos grupos B e C. O número de nódulos de larvas encontrado nos animais do grupo C foi 148,3% maior que nos animais dos grupos A e B. A comprovação da resposta imune celular e humoral, parcialmente caracterizadas, bem como a redução do número de nódulos, são indicadores que a imunização contra D. hominis foi parcialmente protetora para os bovinos imunizados.Dermatobia hominis larvae cause ulcerative lesions and damage to subcutaneous tissue and skin of the host.

The aim of this research is to explain the humoral immune response changes in the dental pulp tissues of pulpitis. This research was done on three group samples: Irreversible pulpitis, Reversible pulpitis and sound teeth as the control group. The result showed that there were three pulpitis immunopathologic patterns: the sound teeth immunopathologic pattern showing a low humoral immune response, in a low level of IgG, IgA and IgM, the reversible pulpitis pattern showing that in a higher humoral immune response, IgG and IgA decreased but IgM increased, the irreversible pulpitis pattern showing that IgG and IgM increased, but it couldn't be repaired although it has highly immunity, and it showed an unusually low level of IgA. This low level of IgA meant that irreversible pulpitis had a low mucosal immunity.

    Full Text Available Os Autores estudaram a resposta imune celular e os níveis de anticorpos na vacinação e re-vacinação canina. A vacina utilizada foi a Fuenzalida & Palacios, empregada rotineiramente na imunização humana e canina, no Brasil. A avaliação da resposta mediada por células foi feita por testes de inibição de migração de leucócitos periféricos. Os níveis de anticorpos foram determinados por provas de soro-neutralização e fixação do complemento. Os cinco cães envolvidos no experimento receberam um esquema inicial de 5 doses e uma dose de reforço 210 dias após. Todos os animais exibiram níveis moderados de anticorpos após o esquema inicial e uma nítida resposta secundária após o reforço. A resposta imune celular, contudo, ocorreu apenas após a imunização inicial, não sendo detectada em resposta à dose de reforço. Concluem os Autores que a resposta imune celular ocorre na primo-vacinação anti-rábica canina nas condições experimentais empregadas e que embora a resposta secundária não tenha sido obtida neste estudo sua existência não pode ser descartada e deve ser reestudada em outras condições.

    Full Text Available The purpose of this work was to evaluate the immune response in goats with different degrees of gastrintestinal nematode infection. Ninety adult animals naturally infected were grouped according to the total egg count per feces gram (EPG: group I from zero to 500 EPG, group II from 501 to 2000 and group III above 2000. The parameters studied were serum total protein (STP, evaluated by biuret method; globulin (Glob, calculated by the difference between STP and serum albumin; gammaglobulin (Gglob, estimated throughout electrophoresis; immunoglobulin (Ig, estimated by turbidometry test with ZnSO4 and absolute lymphocyte count (Lymp / ml. It was found statistically decrease in three parameters (STP, Ig and Lymp / ml for group III. For Glob and Gglob, the decrease found was not statistically significant. These results show a depressor effect of nematode infection on humoral immune system. The intense dispersion of Glob and Gglob data can explain the not significant decrease found in those parameters. It was concluded that goats with intense nematode infection (above 2000 EPG can show immunedepression, with impairment of lymphocyte count and serum antibody level.O objetivo deste trabalho foi estudar a resposta imunológica em caprinos com vários graus de verminose gastrintestinal.

    O gênero Yersinia compreende três espécies patogênicas para humanos: Y. pestis , Y. enterocolitica e Y. pseudotuberculosis . A patogenicidade de Yersinia está ligada à presença do plasmideo de 70-kb (pYV que é comum às três espécies e codifica um sistema de secreção do tipo III e um conjunto de proteínas de virulência, incluindo aquelas conhecidas como Yops (Yersinia outer proteins, que são exportadas por este sistema quando as células do hospedeiro são infectadas pela bactéria. Duas Yops translocadoras (YopB e YopD se inserem na membrana plasmática e funcionam no transporte de seis efetoras (YopO, YopH, YopM, YopJ e YopT para o citosol da célula do hospedeiro. As Yops efetoras funcionam interferindo em múltiplas vias de sinalização da célula infectada. Como conseqüência, a resposta imune inata e adaptativa do hospedeiro fica afetada. Este trabalho enfoca o papel das Yops na modulação da resposta imune do hospedeiro. Palavras-chave: Yersinia ; Yops, fagocitose, citocinas, anticorpos.

    Full Text Available Brucellosis remains an economic problem in animals and public health. Worldwide ovine brucellosis caused by Brucella ovis is considered a major cause of infertility in sheep. The factors responsible for persistence of the agent in these locations are not known, as well as the mechanisms involved in immune defense and possibly the persistence of the agent. Brucella spp. induces moderate inflammatory response. The nature of the intracellular agent stimulates immune response of the type 1 helper T lymphocytes. Studies of the pathogenesis of ovine brucellosis are scarce. Recent developments have shown that the inflammatory response induced by moderate brucelas represent probably the result of an attempt to escape the immune response and suppression of host immune response. Were reviewed by the mechanisms described by brucelas and Brucella ovis for penetration into the host, escape of the immune response and the immune response generated by the infection. A brucelose permanece como problema econômico em animais e de saúde pública. Em todo o mundo a brucelose ovina ocasionada pela Brucella ovis é considerada uma das principais causas de infertilidade em ovinos. Os fatores responsáveis pela persistência do agente nestes locais não são conhecidos, bem como os mecanismos imunes envolvidos na defesa e eventualmente na persistência do agente. Brucella spp. induz resposta inflamatória moderada. A natureza intracelular do agente estimula resposta imune celular do tipo linfócito T helper 1. Os estudos de patogenia da brucelose ovina são escassos. Recentes avanços demonstraram que a resposta inflamatória moderada induzida pelas brucelas representam provavelmente o resultado de tentativa de escape da resposta imune e supressão da resposta imune hospedeira. Foram revisados os mecanismos descritos pelas brucelas e pela Brucella ovis para penetração no hospedeiro, escape da resposta imune, bem como a resposta imunológica gerada pela infecção.

    A tuberculose pulmonar é um problema de saúde pública mundial e apresenta alta incidência no Brasil. Atualmente, o Brasil ocupa o 19º lugar no ranking dos 22 países que concentram 80% dos casos em todo o mundo. A resposta imune humana contra a tuberculose é especialmente mediada pelos linfócitos T CD4+. Entretanto, muitos estudos ainda são necessários para o entendimento exato do papel de cada citocina no mecanismo de cura da doença. A fim de caracterizar a produção das citocin...

    Em bovinos o protozoário Trypanosoma vivax causa enfermidade que pode levar à redução dos índices produtivos ou a morte do animal. O diagnóstico deste protozoário pode ser realizado por testes parasitológicos, sorológicos e moleculares. Entretanto estes testes não são capazes de fornecer prognóstico, indicar a fase da infecção e a responsividade ao tratamento instituído. Por outro lado, o proteinograma sérico pode fornecer tais informações. O objetivo do estudo foi determinar o perfil eletrof...

    Full Text Available Os A.A. analisaram a resposta humoral nas lesões de 90 pacientes de Leishmaniose Tegumentar — causada por Leishmania braziliensis brasiliensis —, utilizando o método da imunoperoxidase para identificar nos tecidos a presença de IgA, IgG, IgM, fração C3 do complemento e fibrina. Constataram a presença de IgA, IgC e IgM nos plasmócitos tissulares, com predomínio de IgG. Admitiram aue a passagem dessas imunoglobulinas para os tecidos possibilitando a opsonização do parasites e/ou de seus antígenos, permitiria a ocorrência de fenômenos necróticos que representam um dos mecanismos eficazes de redução da carga parasitária. Efetivamente, nas áreas de necrose e nas paredes dos vasos inflamados identificaram depósito de imunoglobulinas, fração C3 do complemento e fibrina — elementos do hospedeiro que fazem parte dos imunocomplexos. Interpretaram essa necrose tissular como o resultado da ação de imunocomplexos na região de equivalência ou com discreto excesso de antígenos ítipos ABTHTJS. A presença de antígenos parasitários, expressos nas membranas dos macrófagos quando em contato com imunoglobulinas tissulares, na fase inicial da lesão, possibilitaria a instalação de uma reação antígeno-anticorpo, a qual explicaria o aparecimento da necrose na Leishmaniose Tegumentar.

    Full Text Available Sufficient knowledge of the community regarding benefits of temulawak for health and scientific evidence of its influence on the immune system is crucial for rationalizing the utilization of these plants for health purposes. This study aimed to analyze the public's knowledge about health benefits of temulawak drinks, as well as analyzing the effect of temulawak extract drink consumption on humoral immune system function as assessed by population of B lymphocytes in obese adults. The study consisted of a survey of knowledge about the health benefits of temulawak involving 80 subjects and a clinical trial of the effect of extract temulawak drink consumption given for 2 weeks in 21 obese subjects. Populationof total lymphocytes and B lymphocytes were analyzed before and after intervention. This study showed that the health benefits of temulawak most widely known by subjects were to increase appetite and to maintain stamina. From the clinical trial it was shown that the extract significantly reduce the population of B lymphocytes, indicating a decrease in humoral immune function.

    Full Text Available Humoral and cellular immune responses were evaluated in 44 C57BL/6 mice immunized with the Trypanosoma cruzi recombinant antigens CRA and FRA. Both antigens induced cutaneous immediate-type hypersensitivity response. The levels of IgG1, IgG2a, IgG2b and IgG3 were high in CRA immunized mice. IgG3 was the predominant isotype. Although no difference in antibody levels was observed in FRA-immunized mice when compared to control mice, both antigens were able to induce lymphoproliferation in immunized mice. Significant differences were observed between incorporation of [³H]- thymidine by spleen cell stimulated in vitro with CRA or FRA and the control group. These results suggest that CRA and FRA could be involved in mechanisms of resistance to Trypanosoma cruzi infection.As respostas imune humoral e celular foram avaliadas em 44 camundongos C57Bl/6 imunizados com os antígenos recombinantes CRA e FRA de Trypanosoma cruzi. Ambos antígenos induziram reação de hipersensibilidade do tipo imediato. Os níveis de IgG1, IgG2a, IgG2b e IgG3 foram elevados nos camundongos imunizados com CRA. IgG3 foi o isotipo predominante. Nenhuma diferença nos níveis de anticorpos foi observada em camundongos imunizados com FRA em relação aos animais controle. No entanto, ambos antígenos foram capazes de induzir proliferação de linfócitos em camundongos imunizados. Diferenças significativas foram observadas entre a incorporação da timidina - [³H] pelas células esplênicas estimuladas com CRA ou FRA e o grupo controle. Esses resultados sugerem que CRA e FRA poderão estar envolvidos nos mecanismos de resistência à infecção pelo Trypanosoma cruzi.

    Full Text Available The nutritional and production costs associated with the development of a competent immune response against nematode parasites is described, based on data from sheep. Anorexia and changes in metabolism are considered to be driven by the host immune response itself and the question is raised about the wisdom of seeking to strengthen immune responses by genetic selection. Several phases of the immune response are identified with different implications for loss of productivity and opportunity for moderation of immune responses and production losses by nutrition. Many animals are able to manage nematode infections with little loss of productivity. In an era when attempts are being made to reduce anthelmintic use and create refugia to reduce the rate of development of drench resistance, treatments based on individual animal performance relative to production targets set by assessment of the prevailing nutritional environment will become more common. These developments, have already occurred in relation to the haematophagic nematodes, for example the "Famacha" technique. Computer-aided weighing and drafting has potential for use with the less pathogenic nematodes prevalent in temperate regions though we need to know more about the pathophysiology and nutritional costs of infections with Nematodirus spp.Os custos nutricionais e de produção associados ao desenvolvimento de uma resposta imune competente contra parasitas nematódeos estão descritos nesta revisão, com base em dados com ovinos. Anorexia e mudanças no metabolismo são consideradas o resultado da própria resposta imune do hospedeiro, e a questão é levantada quando se busca o fortalecimento da resposta imune pela seleção genética. Várias fases da resposta imune são identificadas com diferentes implicações, pela perda de produtividade e oportunidade para moderação da resposta imune e pela perda da produção pela nutrição.

A idade das matrizes influenciou a resposta de todas as variáveis. A inclusão de 3kg de parede de levedura/tonelada de ração promoveu, na progênie de reprodutoras de 57 semanas, reação inflamatória mais intensa quando comparada a dieta controle, no entanto não houve aumento significativo no número de heterófilos e linfócitos circulantes. Conclui-se que a utilização da parede de levedura associada ao sorgo ou não em rações de frangos de corte ainda necessita de estudos complementares, que incluam, por exemplo, os componentes purificados da parede de levedura (MOS e ß-glucano.An experiment was carried out to evaluate the effect increasing levels of yeast wall and broiler breeders' age levels on lymphoid organs weight, cellular immune response and hematological parameters in broilers.

Condições ótimas de cromatografia foram validadas por análise estatística. O rendimento médio de parasitas obtidos após separação em colunas de lã de vidro e a viabilidade dos promastigotas foram estimados por microscopia óptica. Os promastigotas metacíclicos tiveram um rendimento médio de 43,5% a 57,5%. Camundongos BALB/c (susceptíveis e camundongos C57BL/6 (resistentes apresentaram padrões distintos de lesões cutâneas, os primeiros com lesões mais agressivas, induzidas por promastigotas metacíclicos. As respostas à reação de HTR foram maiores nos grupos de camundongos C57BL/6, submetidos à infecção com promastigotas metacíclicos. Estes resultados indicam que o novo método poderia ser integrado aos protocolos existentes para estudar a metaciclogênese de parasitas do gênero Leishmania in vivo.

    Full Text Available OBJETIVO: Investigar a resposta humoral para o vírus dengue em pacientes com sequência de Möbius e suas mães, analisando a relação entre a infecção na gestação e o nascimento de portadores da sequência de Möbius. MÉTODOS: Foram revisados os prontuários dos pacientes atendidos em centro de referência. Aplicou-se um questionário estruturado a cada genitora. Sorologia por Elisa para IgG de dengue foi efetuada em 35 pacientes e suas mães. O teste de neutralização por redução em placas foi feito nas que referiram infecção viral na gestação e em seus filhos, para determinar o sorotipo viral causador da infecção. RESULTADOS: Febre, cefaléia e/ou dor retro-orbitária foi referida por 18 (51,4% mães. Três (8,6% referiram dengue no primeiro ou início do segundo trimestre de gestação. Cruzando-se as informações das sorologias das mães e crianças observou-se que em 57,1% dos casos há positividade sorológica para o vírus do dengue na mãe e no filho. Das três mães com infecção na gestação, uma e seu filho, apresentou teste de neutralização por redução em placa positivo para o vírus dengue tipo três (DENV-3, entretanto o sorotipo apenas foi introduzido em Pernambuco em 2002, o que exclui a possibilidade de ter ocorrido transmissão vertical da doença. CONCLUSÃO: As sorologias dos casos que tiveram diagnóstico clínico de dengue na gravidez revelaram-se incompatíveis com a hipótese de ter ocorrido transmissão vertical da doença. Portanto, na amostra estudada, a infecção pelo vírus do dengue não pode ser considerada como fator implicado na gênese da sequência de Möbius.PURPOSE: To investigate the humoral immune response to dengue virus in patients with Möbius sequence and their mothers, assessing the relation between this infection during pregnancy and Möbius sequence.

  15. Making humor together: phenomenology and interracial humor

    Directory of Open Access Journals (Sweden)

    Michael D. Barber

    2016-01-01

    Full Text Available This paper explains humor through phenomenological concepts and methods. The three major theories of humor: Superiority, Relief, and Incongruity depend on the thwarting of intentional expectations. Since one experiences an incongruity between what is intended and what is actually experienced, the incongruity theory affords the best explanation, but intentionality remains fundamental for all theories. Theorists of humor rightly insist that the enjoyment of humorous incongruity completes the definition of humor, but such enjoyment also depends on a special epoché, usually elicited by the cues of an interlocutor who invites the listener to leap together into the humorous finite province of meaning. In this province, actions and statements, hurtful in everyday life, such as a pie thrown at someone who ducks as the pie hits another, produce laughter. This comic epoché resembles the phenomenological epoché in its distancing from everyday life, and, like the phenomenological epoché, it opens everyday experience to reflection. Although one often experiences and enjoys humor alone, humor is thoroughly intersubjective and more frequently occurs when two persons participate in the humorous epoché together. The opportunities for making humor together are enhanced to the extent the partners differ in their expectations and responses to situations. Those differences, including bodily differences, often result from the complex intersubjective networks, including culture. As in the case of a seemingly solitary activity like reflection, which one learns from others and exercises on one’s own autonomously, one internalizes others’ styles of humor and discovers such internalization through reflection on one’s «because motives». On the basis of these features – intentionality, epoché, and intersubjectivity, the paper concludes by briefly examining an example of interracial humor. Despite the racist character of much interracial humor, the example

    Angelo Michele de Candia

    2007-09-01

    Full Text Available Apesar de relativamente recente, nota-se um acúmulo crescente e robusto de evidências experimentais e clínicas que apontam um estado gradativo de ativação imune-inflamatória em pacientes com insuficiência cardíaca (IC. Níveis elevados de diversas citocinas são encontrados na circulação e no músculo cardíaco de indivíduos com IC, correlacionando-se, invariavelmente, com o grau de gravidade da doença e agindo na disfunção endotelial, no estresse oxidativo, na indução de anemia, na apoptose miocitária e na perda gradativa de massa muscular esquelética - no que se convencionou denominar o paradigma inflamatório da IC. Não só o miocárdio, mas diversos tecidos parecem sintetizar tais citocinas e perpetuar esse contínuo estado de inflamação em baixo grau, inclusive leucócitos, monócitos, células musculares esqueléticas e endoteliais - em resposta a estímulos hemodinâmicos, infecciosos, à hipóxia, ao estresse oxidativo e à ativação neuro-humoral, entre outros. Desse modo, forma-se uma rede de moléculas que interagem entre si, estabelecendo, ainda, conexões com outros eixos que efetivamente contribuem para a deterioração clínica dos pacientes - o que se encaixa no modelo fisiopatológico de acometimento multissistêmico que tem sido cada vez mais atribuído à IC. Ainda que a dosagem periférica desses biomarcadores reúna evidências bastante sólidas de poder prognóstico, os resultados dos ensaios terapêuticos que modularam em fase clínica a alça imune-inflamatória foram, até então, pouco encorajadores. Desse modo, acreditamos que é fundamental compreender melhor a ativação inflamatória e sua multifacetada relação com os eixos de descompensação da doença, para que possamos estabelecer novas perspectivas terapêuticas com impacto de relevância em um futuro próximo.Despite being relatively recent, a growing and significant accumulation of experimental and clinical evidence has been observed

    Directory of Open Access Journals (Sweden)

    Luciana Vismari

    2008-01-01

    Full Text Available CONTEXTO: A hipótese monoaminérgica da depressão não responde a uma série de questões, tais como "quais as causas dos distúrbios monoaminérgicos?" e "como explicar uma taxa de 30% de refratariedade aos antidepressivos?". Sendo assim, outras teorias têm sido propostas, entre elas, aquelas que enfocam as participações dos sistemas imune e endócrino. OBJETIVOS: Analisar criticamente o papel do sistema de resposta imunoinflamatória na depressão e discutir a interação dos antidepressivos com esse sistema, tanto do ponto de vista básico como clínico. MÉTODOS: Realizou-se pesquisa bibliográfica utilizando-se as bases de dados MedLine e SciELO. RESULTADOS: Pacientes vítimas de estresse crônico e depressão apresentam ativação das respostas imunoinflamatórias e do eixo hipotálamo-hipófise-adrenal, os quais, direta ou indiretamente, influenciam a neurotransmissão. Nesse sentido, a utilização de antidepressivos não apenas aumenta a disponibilidade de neurotransmissores na fenda sináptica, mas também induz mudança do padrão de resposta imune Th1 - pró-inflamatório - para o Th2, que é antiinflamatório. Além disso, sabe-se que pacientes não responsivos aos antidepressivos possuem o sistema imuneinflamatório mais ativo. No entanto, há uma série de dados controversos na literatura, havendo indícios de um perfil imune diferente de acordo com o tipo de depressão. CONCLUSÕES: A compreensão de aspectos neuroimunes presentes na depressão poderia contribuir para um melhor entendimento das bases biológicas desse transtorno e, possivelmente, para novas perspectivas na busca de uma terapêutica mais efetiva.BACKGROUND: The monoaminergic hypothesis of depression does not answer certain questions, such as "what are the causes of the monoaminergic disturbances?" and "how to explain the existence of 30% refractory patients to antidepressants?".

    Full Text Available O entendimento da interação de nanotubos de carbonos e fulerenos com os constituintes da pele, em especial o sistema imune de pele, é relevante para a determinação de parâmetros toxicológicos. Realizou-se revisão voltada a tais aspectos. Parte considerável das referências encontradas concentrou-se nos efeitos citotóxicos e de permeação da pele. Em menor escala, há artigos sobre ativação e imunomodulação de células e outros elementos imunes. Poucos trabalhos encontrados tratam, especificamente, da resposta imunológica cutânea, limitando o conhecimento relacionado. Os achados sugerem que os nanomateriais analisados possam estar envolvidos em quadros dermatológicos, como dermatite de contato irritativa, reações anafilactoides, urticária e angioedema, e suscitam a necessidade de que se realizem estudos adicionais para confirmação dos achados. A padronização da descrição e testagem de características dos nanomateriais empregados em experimentos pode facilitar a comparação dos resultados.

    Full Text Available O treinamento físico, de intensidade moderada, melhora os sistemas de defesa, enquanto que o treinamento intenso causa imunossupressão. Os mecanismos subjacentes estão associados à comunicação entre os sistemas nervoso, endócrino e imunológico, sugerindo vias autonômicas e modulação da resposta imune. Células do sistema imune, quando expostas a pequenas cargas de estresse, desenvolvem mecanismo de tolerância. Em muitos tecidos tem-se demonstrado que a resposta a situações agressivas parece ser atenuada pelo treinamento físico aplicado previamente, isto é, o treinamento induz tolerância para situações agressivas/estressantes. Nesta revisão são relatados estudos sugerindo os mecanismos adaptativos do sistema imunológico em resposta ao treinamento físico.Moderate physical training enhances the defense mechanisms, while intense physical training induces to immune suppression. The underlying mechanisms are associated with the link between nervous, endocrine, and immune systems. It suggests autonomic patterns and modulation of immune response. Immune cells, when exposed to regular bouts of stress, develop a mechanism of tolerance. In many tissues, it has been demonstrated that the response to aggressive conditions is attenuated by moderate physical training. Thus, training can induce tolerance to aggressive/stressful situations. In this review, studies suggesting the adaptation mechanisms of the immune system in response to physical training will be reported.

  9. Humor in psychiatric healing.

    Saper, B

    1988-01-01

    The oft-quoted aphorism that "laughter is the best medicine" is examined. Specifically, three big drops in the shower of claims regarding the benefits of humor in treating physical and mental disorders are evaluated. First, studies of the effects of mirth and laughter on the physiology of the body reveal both good and bad news. The meager evidence of the salutary effects of positive emotions on the cardiovascular, respiratory, immune and neuroendocrine systems, though apparently supportable on more or less scientific, rational and subjective grounds, needs much better verification from more extensive, replicable, and empirical research. Second, despite numerous claims, in the context of behavioral or psychosomatic medicine, that a joyful, optimistic, or humorous attitude can render a salubrious effect, almost to the extent of preventing illness and curing physical disease, the jury is still out and issuing dire warnings regarding too ready acceptance of this largely anecdotal evidence. Much careful "clinical trial" research needs to be mounted to determine the conditions under which humor works best, if at all. The type of patient, the kind of humor, the type and severity of illness, the psychosocial contexts-all of these factors should be considered. Third, the infusion of humor into psychotherapy is great news for some therapists and awful news for others. A number of more balanced approaches point up the probability that when mirth is incorporated into therapy judiciously, appropriately, and meaningfully it can be of value.

    Full Text Available As concepções dos educandos acerca de um tema, sob a perspectiva cognitivista de aprendizagem, exercem influência sobre os processos de construção do conhecimento realizados pelo aprendiz. Assim, o conhecimento e a reflexão sobre as concepções discentes são pontos importantes para a condução dos processos de ensino e de aprendizagem. Portanto, com base nesses pressupostos, o presente trabalho tem como objetivo apresentar uma análise das concepções dos alunos acerca do tema Imunologia e do tópico sistema imune humano (SIH e suas relações com o ensino e a aprendizagem do tema no contexto de um curso técnico de nível médio de Enfermagem. Para tanto, realizamos uma pesquisa descritiva com abordagem qualitativa. Os dados foram coletados por meio de atividades diagnósticas, entrevistas, observações e gravações de áudio. As análises dos dados foram realizadas com base no método interpretativo hermenêutico, em consonância com a abordagem qualitativa. Mediante as análises foi verificada a atribuição majoritária de ações bélicas ao SIH, como ataque e defesa destinados à proteção do organismo contra a invasão de patógenos e/ou corpos estranhos. Foi identificada a crença de que os microrganismos são inimigos e precisam ser vencidos por linfócitos, anticorpos e fagócitos. A presença da metáfora bélica nas respostas e nas falas dos alunos foi relacionada à compreensão dos fenômenos imunológicos ligados exclusivamente à manutenção da saúde como condição de isenção de corpos estranhos no organismo humano. Foi verificado um limitado conhecimento da fisiologia do sistema imunológico na dinâmica de interações do organismo consigo mesmo e com componentes do ambiente em que este se encontra inserido. Apenas um dos 71 alunos participantes da pesquisa mencionou, indiretamente, a relação do SIH com o conceito homeostase, ou seja, como um sistema que atua na manutenção da estrutura (conservação da

    Full Text Available Resumo: As vitaminas são compostos orgânicos necessários em poucas quantidades no organismo, todavia indispensáveis para as funções metabólicas. Elas se inserem em inúmeras reações metabólicas, fisiológicas e imunes das células, necessárias para a manutenção da saúde animal, além de atuarem como imunoestimulante. Embora a dieta rica em folhagens verdes frescas forneça quantidades suficientes de vitaminas A, D e E a suplementação intensiva com alimentos conservados na forma de feno ou silagem pode reduzir em até 50 % dos teores destas vitaminas no alimento. Diante disso, a proposta do trabalho foi verificar se a administração parenteral de vitaminas A, D e E age como imunoestimulante em garrotes estabulados e alimentados exclusivamente com feno de tifton. Para tanto 14 bovinos foram divididos em dois grupos homogêneos, sendo o grupo S, suplementado com vitamina A, D e E em dose única de 30 mL por via intramuscular; e o grupo C, sem suplementação. Ambos os grupos foram alojados em baias parcialmente privadas de sol, e alimentados com feno por um período de três meses. A avaliação imune foi realizada por hemogramas e ensaio de função leucocitária (metabolismo oxidativo e fagocitose nos momentos antes do tratamento, três e dez dias após os tratamentos. Tendo em vista que a suplementação com polivitamínicos A, D e E aumentou a porcentagem da atividade de células granulocítica e a intensidade da atividade de células mononucleares, além de intensificar o efeito antioxidante prolongando a sobrevida de hemácias e neutrófilos, conclui-se que esta suplementação promoveu efeito benéfico na resposta imune de bezerros da Raça Holandesa, apesar dos efeitos deletérios da alimentação exclusiva com feno e da privação parcial da incidência solar direta.

    2009-09-01

    Full Text Available A imunidade na glândula mamária pode ser classificada, assim como em outros sistemas, em inata ou inespecífica e adaptativa ou específica. A imunidade inata é a defesa predominante durante os estágios iniciais da infecção. As respostas inespecíficas estão presentes no local da infecção ou são ativadas rapidamente por numerosos estímulos e não aumentam pela exposição repetida ao mesmo agente etiológico. O primeiro obstáculo enfrentado por um patógeno para adentrar o úbere é composto pela barreira formada pelo esfíncter do teto e pelo tampão de queratina formado pelo epitélio queratinizado. Uma vez que o microrganismo tenha atravessado o canal do teto e alcançado a cisterna mamária, passam a atuar diversos fatores solúveis e celulares. Dentre os fatores solúveis, estão presentes: lactoperoxidase, sistema complemento, citocinas, lactoferrina, lisozima e NAGase. As defesas celulares inespecíficas na glândula mamária são representadas pelos neutrófilos, pelos macrófagos e pelas células natural killer. Na medida em que esses mecanismos funcionam adequadamente, a maioria dos patógenos será rapidamente eliminada antes que o sistema imune específico seja ativado, sem resultar em alterações na quantidade ou qualidade do leite produzido. Uma melhor compreensão sobre os mecanismos de defesa da glândula mamária e suas alterações durante os períodos críticos da infecção é imprescindível para o desenvolvimento de métodos mais eficazes de profilaxia e controle da mastite, a principal doença dos ruminantes leiteiros. O presente estudo revisou os principais aspectos responsáveis pelo desenvolvimento da imunidade inata na glândula mamária bovina.The immunity in the mammary gland can be, as in other systems, classified in innate or adaptive immunity. The innate immunity is the predominant defense during the initial periods of infection. The non-specifics answers are present or are quickly activated in the

Hal ini terjadi karena kemampuan polimorfisme dari komponen molekul yang terdapat pada permukaan sel presentan pada saat proses respon imun terjadi. Komponen molekul tersebut disebut MHC (Major Hystocompatibility Complex pada tikus diberi kode H-2 atau HLA (Human Leucocyt Antifen pada manusia. Pengkode genetik MHC pada tikus terletak pada kromosom 17, pada manusia terletak pada kromosom 6. MHC tersebar pada hampir semua permukaan sel tubuh. Pada tikus MHC kelas 1 terdapat sel-sel yang berinti, platelet dan sel darah merah. Pada manusia terdapat pada sel-sel yang berinti dan platelet. MHC pada tikus terutama terdapat pada sel B, makrofag, sel epithel, sel limfosit T. Pada manusia terutama terdapat pada sel B dan makrofag. Fungsi MHC kelas I diantaranya adalah reaksi penolakan jaringan, stimulasi produksi antibodi, proses interaksi antigen dengan sel T. MHC kelas II diperlukan dalam proses presentasi antigen. Pengetahuan tentang MHC/HLA seseorang, dapat dipakai untuk memperkirakan risiko seseorang mendapatkan penyakit yang bersifat herediter atau kelainan imunologik. Dengan mengetahui bahwa MHC/HLA hanya dapat mengikat peptida, hal ini dapat dimanfaatkan untuk pencegahan reaksi alergi.

    Full Text Available O Pythium insidiosum é um fungo zoospórico que se desenvolve em locais alagadiços e que pode infectar humanos e animais, principalmente eqüinos. A infecção natural nesta espécie resulta em pitiose clínica, uma doença granulomatosa de difícil tratamento. Uma das opções terapêuticas é a imunoterapia com antígenos obtidos de culturas do agente. Com o objetivo de avaliar o efeito de adjuvantes na resposta sorológica a antígenos do P. insidiosum, 24 coelhos divididos em 4 grupos foram imunizados com antígeno macerado de micélio (AMM associado a três adjuvantes. Grupo I: hidróxido de alumínio; grupo II: adjuvante de Freund; grupo III: óleo mineral e grupo IV: água destilada -controle. Os tratamentos foram avaliados a diferentes intervalos, quanto à capacidade de induzir a produção de imunoglobulinas específicas da classe G, através da técnica de ELISA. Na fase 1, os animais receberam três doses do imunógeno (dias zero, 14 e 28 e foram avaliados sorologicamente nos dias 14, 21, 28 e 35. Nessa fase, os adjuvantes oleosos (GII e III induziram níveis de anticorpos estatisticamente superiores aos induzidos nos grupos I e IV. Durante a fase 2 (dias 42 a 120, cada grupo foi subdividido em dois; sendo um subgrupo mantido em tratamento (imunizações adicionais nos dias 42, 56, 68 e 82 e o outro tendo o tratamento interrompido após a 3ª dose (dia 28. Nos subgrupos mantidos em tratamento, os níveis de anticorpos dos grupos imunizados com adjuvantes foram estatisticamente superiores aos induzidos no grupo GIV (controle. Nos coelhos com tratamento interrompido, os grupos I, II e III apresentaram manutenção nos níveis de IgG e foram estatisticamente superiores ao grupo controle, que apresentou declínio nos níveis de anticorpos. Os resultados demonstraram a capacidade dos adjuvantes testados em potencializar e prolongar a resposta humoral aos antígenos do P. insidiosum. O uso de adjuvantes associado aos atuais imun

    Full Text Available OBJETIVO: Avaliar os resultados da esplenectomia vídeo-laparoscópica para pacientes portadores de Púrpura Trombocitopênica Imune. MÉTODO: Estudo prospectivo de 17 pacientes portadores de Púrpura Trombocitopênica Imune submetidos a esplenectomia vídeo-laparoscópica com uso de três trocartes e ligadura com fio do hilo esplênico, no Hospital Universitário Clementino Fraga Filho - UFRJ, Rio de Janeiro, no período de janeiro de 2001 a julho de 2003. Foram avaliadas as taxas de conversão, transfusão e de remissão da doença, os tempos operatório, anestésico e de internação, além das incidências de complicações e de baços acessórios. RESULTADOS: Nos 17 pacientes submetidos à técnica, não houve conversão para cirurgia aberta. Complicações ocorreram em três pacientes (17,6%: um hematoma subcutâneo, um tecido esplênico residual, um pseudocisto pancreático. Reoperação foi necessária em um paciente, 24 meses após a esplenectomia, para retirada de tecido esplênico residual, sem plaquetopenia. Foi necessária a colocação adicional de um trocarte de 5mm em quatro pacientes. Não houve óbitos. O tempo operatório médio foi de 132,9min e o tempo médio de internação de 2,53 dias. Foi necessária transfusão de plaquetas em dois pacientes (11,8%. Baço acessório foi encontrado em quatro pacientes (23,5%. Responderam favoravelmente à esplenectomia 13 pacientes (76,5%, ocorrendo nenhuma resposta ou não duradoura em quatro pacientes (23,5%. CONCLUSÕES: Cuidados no per- operatório são importantes para evitar a disseminação de tecido esplênico, a não identificação de baços acessórios e a técnica mais anatômica para evitar lesões pancreáticas, hemorragia e conversão. Os pacientes com PTI respondem em proporções semelhantes à cirurgia aberta comparados com dados da literatura, com menor índice de complicações e menor tempo de internação.

    Humor has neurophysiological effects influencing the release of cortisol, which may have a direct impact on the immune system. Laughter is associated with a decreased production of inflammatory cytokines both in the general population and in rheumatoid arthritis (RA). Our objective was to explore the effects of humor on serum cytokines [particularly interleukin-6 (IL-6)] and cortisol levels in systemic lupus erythematosus (SLE), after a standard intervention (120 min of visual comedy). We enrolled 58 females with SLE from consecutive patients assessed in the Montreal General Hospital lupus clinic. The subjects who consented to participate were randomized in a 1:1 ratio to the intervention (watching 120 min of comedy) or control group (watching a 120 min documentary). Measurements of cytokine and serum cortisol levels as well as 24-h urine cortisol were taken before, during, and after the interventions. We compared serum cytokine levels and serum and 24-h urine cortisol levels in the humor and control groups and performed regression analyses of these outcomes, adjusting for demographics and the current use of prednisone. There were no significant differences between the control and humor groups in demographics or clinical variables. Baseline serum levels of IL-6, IL-10, tumor necrosis factor-alpha, and B-cell activating factor were also similar in both groups. There was no evidence of a humor effect in terms of decreasing cytokine levels, although there was some suggestion of lowered cortisol secretion in the humor group based the 24-h urinary cortisol levels in a subgroup. In contrast to what has been published for RA, we saw no clear effects of humor in altering cytokine levels in SLE, although interesting trends were seen for lower cortisol levels after humor intervention compared with the control group.

    Humor seems to manifest differently in Western and Eastern cultures, although little is known about how culture shapes humor perceptions. The authors suggest that Westerners regard humor as a common and positive disposition; the Chinese regard humor as a special disposition particular to humorists, with controversial aspects. In Study 1, Hong Kong participants primed with Western culture evaluate humor more positively than they do when primed with Chinese culture. In Study 2a, Canadians evaluate humor as being more important in comparison with Chinese participants. In Study 2b, Canadians expect ordinary people to possess humor, while Chinese expect specialized comedians to be humorous. The implications and limitations are discussed.

Nove anos depois apresentou recidiva que inicialmente respondeu à pulsoterapia corticóide mas foi seguida de perda progressiva e completa da visão após a redução do tratamento. Novas tentativas terapêuticas não melhoraram a visão. Avaliação clínico-laboratorial não revelou doença sistêmica, mas apresentava anticorpos antinucleares (1/640, anti-Ro e anti-La positivos. Neuropatia óptica auto-imune é uma afecção rara, que simula neurite óptica idiopática e se caracteriza por perda visual aguda, sem doença sistêmica, mas com evidências laboratoriais de doença auto-imune, em especial o FAN positivo. Biópsia de pele freqüentemente mostra evidências de vasculite. Esta condição deve ser tratada agressivamente, com corticóide e imunossupressores, uma vez que o acometimento visual geralmente é mais grave do que o da neurite óptica idiopática/desmielinizante e pode ser irreversível.We report on a 9-year-old female patient who had bilateral severe visual loss and was treated with oral corticosteroids. Visual improvement occurred in one eye. Nine years later she presented relapse of visual loss in her only seeing eye. Pulse corticosteroid therapy resulted in dramatic visual improvement followed, however, by progressive and complete visual loss as soon as the corticosteroid was tapered. Repeat treatment did not result in visual improvement. Clinical and laboratory investigation failed to find a systemic disease but the patient had positive antinuclear (1/640, anti-Ro and anti-La antibodies. Autoimmune optic neuropathy is a rare condition that may mimic an idiopathic optic neuritis and is characterized by acute visual loss, without systemic disease but with laboratory evidence of an autoimmune disorder, usually a positive ANA.

    Full Text Available A leucemia linfocítica crônica (LLC é freqüentemente associada a manifestações auto-imunes principalmente relacionadas às células do sistema hematopoético causando anemia hemolítica auto-imune (AHAI, púrpura trombocitopênica imune (PTI, aplasia pura de série vermelha (APSV, e neutropenia imune. A LLC é diagnosticada em até 15% dos pacientes com AHAI, e em cerca de 50% dos pacientes com AHAI secundária a doença maligna. A PTI ocorre em 2%, e a APSV em 1% dos pacientes com LLC. Prednisona é o tratamento inicial de escolha para a citopenia imune associada à LLC. Para cerca de 60% dos pacientes que apresentam recidiva da manifestação auto-imune tem sido utilizada esplenectomia, imunoglobulina endovenosa, ou ciclosporina. Embora as evidências sobre fisiopatologia sejam limitadas, os mecanismos fisiopatológicos da auto-imunidade na LLC estão relacionados à atividade dos linfócitos B leucêmicos que atuam como células apresentadoras de antígeno aberrantes, e são eficientes em processar e apresentar proteínas da membrana de hemácias e de plaquetas às células TH auto-reativas. Linfócitos TH específicos para certos auto-antígenos podem escapar de mecanismos de controle de auto-tolerância, e, se ativados, podem causar doença auto-imune. O diagnóstico de AHAI contra-indica o uso de fludarabina em pacientes com LLC, pois esse análogo da purina tem sido associado ao desenvolvimento de AHAI grave e fatal, com risco consideravelmente mais alto para pacientes mais imunossuprimidos devido a vários tratamentos anteriores.Chronic lymphocytic leukemia (CLL is frequently associated with autoimmune diseases directed against hematopoietic cells, including autoimmune hemolytic anemia (AIHA, immune thrombocytopenic purpura (ITP, pure red cell aplasia (PRCA, and immune neutropenia.

    Full Text Available The present study examined the relationships between dispositional approach and avoidance motives, humor styles, and happiness. In keeping with previous research, approach motives and the two positive humor styles (self-enhancing and affiliative positively correlated with happiness, whereas avoidance motives and the two negative humor styles (self-defeating and aggressive negatively correlated with happiness. Also, we found support for three new hypotheses. First, approach motives correlated positively with self-enhancing and affiliative humor styles. Second, avoidance motives correlated positively with self-defeating humor style, and third, the positive relationship between approach motives and happiness was mediated by self-enhancing humor style.

  4. Humor as a Mental Fitness Indicator

    2008-10-01

    Full Text Available To explain the pervasive role of humor in human social interaction and among mating partner preferences, Miller (2000a proposed that intentional humor evolved as an indicator of intelligence. To test this, we looked at the relationships among rater-judged humor, general intelligence, and the Big Five personality traits in a sample of 185 college-age students (115 women, 70 men. General intelligence positively predicted rater-judged humor, independent of the Big Five personality traits. Extraversion also predicted rater-judged humor, although to a lesser extent than general intelligence. General intelligence did not interact with the sex of the participant in predicting rating scores on the humor production tasks. The current study lends support to the prediction that effective humor production acts as an honest indicator of intelligence in humans. In addition, extraversion, and to a lesser extent, openness, may reflect motivational traits that encourage humor production.

    2012-01-01

    Full Text Available The paper is trying to establish the difference in the use of personal pronouns in 'Misal hruacki' (1531 printed by Šimun Kožičić Benja in comparison to three previously printed missals: 'Misal Pavla Modrušanina '(1528, 'Senjski misal '(1494', Prvotisak misala' (1483, and Vulgata respectively. The pronouns' analysis shows a certain incongruity between Kožičić's text and the other ones. The observed differences are as follows: the use of different morphological form (eg. the accusative case of masculine gender ga – i, the use of different grammatical form in terms of reflexiveness (mene – sebe, and introducing mnê as the genitive and accusative case of pronoun azь. The conclusion is that Kožičić modernized some segments of his printed book (the above mentioned accusative case of masculine gender, but also introduced certain distinctions (eg. mêne, mene, menê that encumbered graphic setup of the printed book. Such distinctions are the result of unsystematic graphic recording of the phoneme e, recorded by Kožičić as the grapheme jat or the grapheme e. However, the use of the majority of forms, particularly plural ones, is identical to other analyzed texts. In the comparative analysis of pronouns it is evident that Kožičić, to some extent, collates his text to the Latin model, but considerably less than when adapting verb forms.

    Research has shown that a factor in a victim's forgiveness of an offender is the victim's ability to make more positive, or at least less negative, attributions of the offender's behavior and that perspective-taking can be a factor in facilitating that process. Self-enhancing humor has been found to be positively correlated with perspective-taking empathy and aggressive humor found to be negatively correlated with perspective-taking empathy. Therefore it was predicted that self-enhancing humor would be positively correlated with forgiveness and aggressive humor negatively correlated with forgiveness. The Humor Styles Questionnaire, the Absence of Negative and Presence of Positive subscales of the Forgiveness Scale, and the Forgiveness Likelihood Scale were administered to 112 college undergraduates. Self-enhancing humor was significantly and positively correlated with all of the forgiveness measures, aggressive humor and self-defeating humor were significantly and negatively correlated with some of the forgiveness measures and affiliative humor was not significantly correlated with any of the forgiveness measures. The results were interpreted in terms of previous findings for humor styles, perspective-taking empathy, depression, self-esteem and anxiety. Future research involving the extent to which other personality variables, such as perspective-taking empathy, mediate the relationship between self-enhancing humor and forgiveness was suggested.

    Full Text Available A corpus of 313 freshman college essays was analyzed in order to better understand the forms and functions of humor in academic writing. Human ratings of humor and wordplay were statistically aggregated using Factor Analysis to provide an overall Humor component score for each essay in the corpus. In addition, the essays were also scored for overall writing quality by human raters, which correlated (r = .195 with the humor component score. Correlations between the humor component scores and linguistic features were examined. To investigate the potential for linguistic features to predict the Humor component scores, regression analysis identified four linguistic indices that accounted for approximately 17.5% of the variance in humor scores. These indices were related to text descriptiveness (i.e., more adjective and adverb use, lower cohesion (i.e., less paragraph-to-paragraph similarity, and lexical sophistication (lower word frequency. The findings suggest that humor can be partially predicted by linguistic features in the text. Furthermore, there was a small but significant correlation between the humor and essay quality scores, suggesting a positive relation between humor and writing quality.

MÉTODO: Os artigos foram selecionados por meio de busca eletrônica no indexador PubMed. Capítulos de livros e as listas de referências dos artigos selecionados também foram revisados. RESULTADOS: Observam-se elevados índices de comorbidade entre abuso/dependência de cannabis e transtornos afetivos em estudos transversais e em amostras clínicas. Estudos longitudinais indicam que, em longo prazo, o uso mais intenso de cannabis está relacionado com um risco maior de desenvolvimento de doença bipolar e, talvez, depressão maior em indivíduos inicialmente sem quadros afetivos; porém, os mesmos não encontraram maior risco de uso de cannabis entre aqueles com mania ou depressão sem esta comorbidade. Outra importante observação é que o uso de substâncias psicoativas em bipolares pode estar associado a uma série de características negativas, como dificuldade na recuperação dos sintomas afetivos, maior número de internações, piora na adesão ao tratamento, risco aumentado de suicídio, agressividade e a uma pobre resposta ao lítio. Tratamentos psicossociais e farmacológicos são indicados para o manejo da comorbidade entre cannabis e transtornos afetivos. CONCLUSÃO: As relações entre o uso de cannabis e alterações do humor são observadas tanto epidemiologicamente quanto nos contextos clínicos.OBJECTIVE: Evaluate the relationship between acute and chronic use of cannabis and mood changes. METHOD: Articles were selected by electronic search in PubMed. Chapters in books and reference lists of selected articles were also reviewed.

    Full Text Available Este artigo examina a construção social e cultural de um estereótipo sobre lésbicas, baseado na percepção de que elas não possuem senso de humor. Analisa-se como lésbicas são retratadas por comediantes, programas de TV,  quadrinhos e na literatura, e compara essas representações a outros  estereótipos, como aqueles relacionados a alemães e gays extravagantes. Ao investigar as relações entre masculinidade, feminilidade e falta de humor, demonstra-se que considerar lésbicas como incompatíveis com o riso e a graça significa caracterizá-las como destituídas de humanidade. The article Humorless lesbians examines the social and cultural construction of a lesbian stereotype, based on the perception that they lack sense of humor. It is analyzed how lesbians are portrayed by comedians, TV shows, comic strips, and in literature. These representations are compared to other stereotypes such as those related to Germans and campy gays. By investigating the relations between masculinity, femininity and humorlessness, it is demonstrated that considering lesbians as incompatible with laughter and fun means to depicting them as deprived of humanity.

    Full Text Available ResumoA crescente exposição a estressores na vida cotidiana aumentou significativamente a investigação da resposta ao estresse nas duas últimas décadas. Embora associada a consequências negativas, pois muitas patologias físicas e mentais são desencadeadas por exposição crônica a estressores, esta resposta é indispensável para sobrevivencia do indivíduo e é extremamente adaptativa quando ativada de forma aguda. Na parte I desta revisão foram abordados os conceitos de homestase e alostase e os sistemas fisiológicos ativados durante a resposta ao estresse. Na parte II serão discutidos fatores que modulam a resposta ao estresse tais como sexo, temperamento, períodos críticos do desenvolvimento e a presença ou ausência de suporte social. A interação entre os fatores genéticos e ambientais gera os perfis da resposta psicofisiológica que caracterizam os fenótipos de susceptibilidade e resiliência frente aos estressores e sua relação com uma patologia mental cada vez mais presente na sociedade moderna, o transtorno de estresse pós-traumático.

  2. Instructional scientific humor in the secondary classroom

    Wizner, Francine

    This study is an examination of the manner in which educators employ scientific content humor and how that humor is perceived by their students. Content humor is a useful strategy in drawing the attention of students and improving their receptivity toward scientific information. It is also a useful tool in combating the growing distractions of the electronic classroom. Previous studies have found that humor has a positive effect on knowledge, memory, and understanding. However, few studies have been conducted below the undergraduate level and mainly quantitative measures of student recall have been used to measure learning. This study employed multiple data sources to determine how two secondary biology teachers used humor in order to explain scientific concepts and how their students perceived their teachers' use of scientific instructional humor. Evidence of student humor reception was collected from four students in each of the two classes. All of the scientific instructional humor used in the studied classrooms was cognitive in nature, varying among factual, procedural, conceptual, and metacognitive knowledge. Teachers tended to use dialogic forms of humor. Their scientific humor reflected everyday experiences, presented queries, poked fun at authority, and asked students to search out new perspectives and perform thought experiments. Teachers were the primary actors in performing the humorous events. The events were sometimes physical exaggerations of words or drawings, and they occurred for the purpose of establishing rapport or having students make connections between scientific concepts and prior knowledge. Student perceptions were that teachers did employ humor toward instructional objectives that helped their learning. Helping students become critical thinkers is a trademark of science teachers. Science teachers who take the risk of adopting some attributes of comedians may earn the reward of imparting behaviors on their students like critical thinking

    To evaluate aqueous humor viscosity in the raptor, dog, cat, and horse, with a primary focus on the barred owl (Strix varia). Twenty-six raptors, ten dogs, three cats, and one horse. Animals were euthanized for reasons unrelated to this study. Immediately, after horizontal and vertical corneal dimensions were measured, and anterior chamber paracentesis was performed to quantify anterior chamber volume and obtain aqueous humor samples for viscosity analysis. Dynamic aqueous humor viscosity was measured using a dynamic shear rheometer (AR 1000 TA Instruments, New Castle, DE, USA) at 20 °C. Statistical analysis included descriptive statistics, unpaired t-tests, and Tukey's test to evaluate the mean ± standard deviation for corneal diameter, anterior chamber volume, and aqueous humor viscosity amongst groups and calculation of Spearman's coefficient for correlation analyses. The mean aqueous humor viscosity in the barred owl was 14.1 centipoise (cP) ± 9, cat 4.4 cP ± 0.2, and dog 2.9 cP ± 1.3. The aqueous humor viscosity for the horse was 1 cP. Of the animals evaluated in this study, the raptor aqueous humor was the most viscous. The aqueous humor of the barred owl is significantly more viscous than the dog (P humor viscosity of the raptor, dog, cat, and horse can be successfully determined using a dynamic shear rheometer. © 2014 American College of Veterinary Ophthalmologists.

  6. Cognitive Distortions, Humor Styles, and Depression.

    2016-08-01

    Cognitive distortions are negative biases in thinking that are theorized to represent vulnerability factors for depression and dysphoria. Despite the emphasis placed on cognitive distortions in the context of cognitive behavioural theory and practice, a paucity of research has examined the mechanisms through which they impact depressive symptomatology. Both adaptive and maladaptive styles of humor represent coping strategies that may mediate the relation between cognitive distortions and depressive symptoms. The current study examined the correlations between the frequency and impact of cognitive distortions across both social and achievement-related contexts and types of humor. Cognitive distortions were associated with reduced use of adaptive Affiliative and Self-Enhancing humor styles and increased use of maladaptive Aggressive and Self-Defeating humor. Reduced use of Self-Enhancing humor mediated the relationship between most types of cognitive distortions and depressed mood, indicating that distorted negative thinking may interfere with an individual's ability to adopt a humorous and cheerful outlook on life (i.e., use Self-Enhancing humor) as a way of regulating emotions and coping with stress, thereby resulting in elevated depressive symptoms. Similarly, Self-Defeating humor mediated the association of the social impact of cognitive distortions with depression, such that this humor style may be used as a coping strategy for dealing with distorted thinking that ultimately backfires and results in increased dysphoria.

  9. The First Joke: Exploring the Evolutionary Origins of Humor

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Humor is a complex cognitive function which often leads to laughter. Contemporary humor theorists have begun to formulate hypotheses outlining the possible innate cognitive structures underlying humor. Humor's conspicuous presence in the behavioral repertoire of humankind invites adaptive explanations. This article explores the possible adaptive features of humor and ponders its evolutionary path through hominid history. Current humor theories and previous evolutionary ideas on humor are reviewed. In addition, scientific fields germane to the evolutionary study of humor are examined: animal models, genetics, children's humor, humor in pathological conditions, neurobiology, humor in traditional societies and cognitive archeology. Candidate selection pressures and associated evolutionary mechanisms are considered. The authors conclude that several evolutionary-related topics such as the origins of language, cognition underlying spiritual feelings, hominid group size, and primate teasing could have special relevance to the origins of humor.

    2015-10-01

    Full Text Available This study examined women’s and men’s preferences for humor production and humor receptivity in long-term and short-term relationships, and how these factors interact with physical attractiveness to influence desirability. Undergraduates viewed photographs of the opposite sex individuals who were high or low in physical attractiveness, along with vignettes varying in humor production and receptivity. Participants rated physical attractiveness and desirability for long-term and short-term relationships. The main findings were that individuals desired partners who were high in humor production and receptivity, though the effects were particularly pronounced for women judging long-term relationships. Moreover, humor production was more important than receptivity for women’s ratings of male desirability. Notably, we also found that ratings of physical attractiveness were influenced by the humor conditions. These results are discussed in terms of the fitness indicator, interest indicator, and encryption hypotheses of the evolutionary functions of humor.

  14. Humor and creative life styles.

    2001-01-01

    This paper is based upon the writings of William James in the late 19th century, and Alfred Adler and Sigmund Freud in the 20th, enriched by the contributions of later personality and role theorists. The self is defined as the unique organization of each person; a style is the self in action. Different life styles and their components are expressed in different situations. I posit that humor and positive thinking, combined with meaning and purpose, are vital components of all constructive life styles. The knowledge of life styles cuts through diagnostic labels to reveal our universal humanity. It can be fruitfully applied to patients and nonpatients alike and, I found, for the self-understanding of therapist. The clinical application of life styles is illustrated through numerous vignettes.

    Full Text Available Ética del humor es una obra original, abundantemente documentada, de contenido científico y filosófico, que aborda un problema de gran importancia en los actuales estudios de éticas aplicadas. La ética del humor es una nueva ética aplicada que pretende comprender el fenómeno del humor a la luz de sus implicaciones éticas. Como señala el autor, Juan Carlos Siurana, reputado experto en el ámbito de la filosofía práctica, el interés por el humor es un interés por la ética. En la obra no presenta una nueva teoría filosófica del humor –las cuales se han venido sucediendo, al menos, desde los Diálogos de Platón–, sino una nueva teoría ética, que toma al humor como objeto principal de análisis. Por tanto, la finalidad es realizar una aportación dentro del ámbito de la ética. Para ello se nutre de distintos estudios psicológicos, biológicos, fisiológicos y neurológicos sobre el humor, así como de clásicas obras de filosofía que han abordado esta cuestión.

    Unlike passive humor appreciation, the neural correlates of real-time humor creation have been unexplored. As a case study for creativity, humor generation uniquely affords a reliable assessment of a creative product's quality with a clear and relatively rapid beginning and end, rendering it amenable to neuroimaging that has the potential for reflecting individual differences in expertise. Professional and amateur "improv" comedians and controls viewed New Yorker cartoon drawings while being scanned. For each drawing, they were instructed to generate either a humorous or a mundane caption. Greater comedic experience was associated with decreased activation in the striatum and medial prefrontal cortex (mPFC), but increased activation in temporal association regions (TMP). Less experienced comedians manifested greater activation of mPFC, reflecting their deliberate search through TMP association space. Professionals, by contrast, tend to reap the fruits of their spontaneous associations with reduced reliance on top-down guided search.

  11. Neuropsychology of humor: an introduction. Part II. Humor and the brain.

    Science.gov (United States)

    Derouesné, Christian

    2016-09-01

    Impairment of the perception or comprehension of humor is observed in patients with focal brain lesions in both hemispheres, but mainly in the right frontal lobe. Studies by functional magnetic resonance imaging in healthy subjects show that humor is associated with activation of two main neural systems in both hemispheres. The detection and resolution of incongruity, cognitive groundings of humor, are associated with activation of the medial prefrontal and temporoparietal cortex, and the humor appreciation with activation of the orbito-frontal and insular cortex, amygdala and the brain reward system. However, activation of these areas is not humor-specific and can be observed in various cognitive or emotional processes. Event-related potential studies confirm the involvement of both hemispheres in humor processing, and suggest that left prefrontal area is associated with joke comprehension and right prefrontal area with the resolution stage. Humor thus appears to be a complex and dynamic functional process involving, on one hand, two specialized but not specific neural systems linked to humor apprehension and appreciation, and, on the other hand, multiple interconnected functional brain networks including neural patterns underlying the moral framework and belief system, acquired by conditioning or imitation during the cognitive development and social interactions of the individual, and more distributed systems associated with the analysis of the current context of humor occurrence. Disturbances of the sense of humor could then result from focal brain alterations localized in one or two of the specialized areas underlying the comprehension or appreciation of humor, or from perturbations of the network interconnectivity in non-focal brain disorders such as Alzheimer's disease or schizophrenia.

  17. Sense of Humor, Stable Affect, and Psychological Well-Being

    Directory of Open Access Journals (Sweden)

    Arnie Cann

    2014-08-01

    Full Text Available A good sense of humor has been implicated as a quality that could contribute to psychological well-being. The mechanisms through which sense of humor might operate include helping to reappraise threats, serving as a character strength, or facilitating happiness. The current research attempts to integrate these possibilities by examining whether a good sense of humor might operate globally by helping to maintain a more stable positive affect. Stable positive affect has been shown to facilitate more effective problem solving and to build resilience. However, not all humor is adaptive humor, so we also examine the roles that different styles of humor use might play. Individual differences in humor styles were used to predict stable levels of affect. Then, in a longitudinal design, humor styles and stable affect were used to predict subsequent resilience and psychological health. The results indicated that stable affect was related to resilience and psychological well-being, and that a sense of humor that involves self-enhancing humor, humor based on maintaining a humorous perspective about one’s experiences, was positively related to stable positive affect, negatively related to stable negative affect, and was mediated through stable affect in influencing resilience, well-being and distress. Thus, while a good sense of humor can lead to greater resilience and better psychological health, the current results, focusing on stable affect, find only self-enhancing humor provides reliable benefits.

    Humor is sometimes employed in health messages. However, little is known about contingencies under which different types of humor may or may not be effective. This experiment crossed humorous vs. non-humorous and self- vs. other-deprecating messages about binge drinking, and tested how differences in personal investment in alcohol use moderates the effects of such messages on college binge drinkers. Results showed significant three-way interaction effects on subjective norms and behavioral intentions largely consistent with hypotheses. Assessment of significant differences in the interactions indicated that for binge drinkers who weren’t high in personal investment in alcohol use, other-deprecating humor tended to reduce their perceived subjective norms about the acceptability of binge drinking behavior and their behavioral intentions. The effect of the experimental manipulation on subjective norms among these binge drinkers was shown to mediate the effect on intentions to binge drink in the future. Theoretical and practical implications are discussed. PMID:26020507

    It has become critical that learners are exposed to varied methods of teaching and assessment that will promote critical thinking of learners. Humor creates a relaxed atmosphere where learning can be enhanced and appreciated. When learners are relaxed, thinking becomes eminent. Authoritative and tense environment hinders thinking. This paper seeks to explore the perceptions of nurse teacher learners regarding the use of humor as a pedagogical tool to promote learning. A qualitative, exploratory, descriptive and contextual research design was employed (Burns & Grove, 2001:61; Mouton, 1996:103). 130 naive sketches were collected from nurse teacher learners who volunteered to take part in the study (Giorgi in_Omery, 1983:52) Follow up interviews were conducted to verify the findings. A qualitative, open-coding method of content analysis was done Tesch (in Creswell, 1994:155). Measures to ensure trustworthiness of the study were taken in accordance with the protocol of (Lincoln & Guba, 1985:290-326). The findings of the study will assist the nurse educators to create a positive, affective, psychological and social learning environment through the use of humor in a positive manner. Nurse educators will appreciate the fact that integration of humor to the learning content will promote the learners' critical thinking and emotional intelligence. Negative humor has a negative impact on learning. Learner nurses who become critical thinkers will be able to be analytical and solve problems amicably in practice.

  1. Adult Playfulness, Humor Styles, and Subjective Happiness.

    Playfulness has been referred to as a disposition that involves reframing a situation to amuse others and to make the situation more stimulating and enjoyable. It may serve to shift one's perspective when dealing with environmental threats. Despite all the benefits of playfulness towards psychological well-being, it remains a largely understudied subject in psychology, particularly in Chinese societies. Hence, this study examined the association between adult playfulness, humor styles, and subjective happiness among a sample of 166 university students in Hong Kong and 159 students in Guangzhou, who completed a self-administered questionnaire, including the Short Measure for Adult Playfulness, the Chinese Humor Styles Questionnaire, and the Subjective Happiness Scale. Results showed that adult playfulness was positively correlated with affiliative humor, self-enhancing humor, and subjective happiness in both Hong Kong and Guangzhou samples. By its implication, highly playful Chinese students preferred using affiliative and self-enhancing humor to amuse themselves and others. © The Author(s) 2016.

  2. Anomalous hypothalamic responses to humor in cataplexy.

    Full Text Available Cataplexy is observed in a subset of patients with narcolepsy and affects approximately 1 in 2,000 persons. Cataplexy is most often triggered by strong emotions such as laughter, which can result in transient, yet debilitating, muscle atonia. The objective of this study was to examine the neural systems underlying humor processing in individuals with cataplexy.While undergoing functional Magnetic Resonance Imaging (fMRI, we showed ten narcolepsy-cataplexy patients and ten healthy controls humorous cartoons. In addition, we examined the brain activity of one subject while in a full-blown cataplectic attack. Behavioral results showed that participants with cataplexy rated significantly fewer humorous cartoons as funny compared to controls. Concurrent fMRI showed that patients, when compared to controls and in the absence of overt cataplexy symptoms, showed pronounced activity in the emotional network including the ventral striatum and hypothalamus while viewing humorous versus non-humorous cartoons. Increased activity was also observed in the right inferior frontal gyri--a core component of the inhibitory circuitry. In comparison, the one subject who experienced a cataplectic attack showed dramatic reductions in hypothalamic activity.These findings suggest an overdrive of the emotional circuitry and possible compensatory suppression by cortical inhibitory regions in cataplexy. Moreover, during cataplectic attacks, the hypothalamus is characterized by a marked decrease in activity similar to that observed during sleep. One possible explanation for these findings is an initial overdrive and compensatory shutdown of the hypothalamus resulting in full cataplectic symptoms.

  3. Humor as Wisdom for Reframing Life.

    Human beings inevitably experience anxiety but attempt to avoid facing it through various forms of self-deception. This avoidance can lead to pathological symptoms. Young and middle-aged adults may be especially susceptible to suffering from anxiety because they are often single-mindedly pursuing means of achieving security. For these and others who fail to embrace life with warm enthusiasm, humor can serve to alleviate stress. This article views humor as a characteristic disposition of older adults-their humor signifying a sense of integrity and wisdom that often accompanies the aging process. Humor binds together feelings of despair and joy and contributes to a faithful reframing of faith and life. This article proposes that individuals acquire humor by perceiving the world as if on a journey to an exotic new place, seeing with new eyes even the most mundane of everyday objects and events. This capacity to perceive beauty in the ordinary world reflects a wisdom of older adults potentially available even to the young.

    This survey study has five parts. In the first part two conceptual approaches to humor are characterized. One considers "the comic" to be an umbrella concept, and humor is only one of its rather positive forms. The other comes out from the umbrella concept "humor", and distinguishes between various forms of humor including the negative ones. Three main theories of humor are presented: theory of superiority, theory of incongruity, and a relief theory. The second part introduces humor in the elderly and draws the attention to the fact that we know relatively little about humor in old age because most research has been carried out in children, adolescents or adults in productive age. The third part of the study describes the process of diagnostics of humor in the elderly. For example, within the qualitative methods, in-depth interviews with seniors or analyses of their diary entries are used. Within quantitative methods, questionnaires are used, and this study presents the survey of seven most frequent ones applied in the studies of humor in the elderly. In the context of mixed methods, understanding of humor in young and seniors, or understanding of humor in relatively healthy seniors and seniors after stroke are compared. The fourth part of the study presents the Gelkopfs model on relationship between humor, treatment and cure of patients. The fifth part of the study demonstrates the options how to use humor to improve the mental state of the elderly (by means of individual or group interventions).

    Humor and laughter are integral parts of human life and communication - and so of course they occur in medical contacts.Humor is defined as a personality based cognitive emotional style of processing situations, characterized by the ability to find positive aspects even in negative situations, and the ability to communicate this point of view to others and to cheer them up. Humor can support healing processes and coping with illness. Humor and jokes reduce anxiety and stress (for patients and doctors). Humorous people have a more realistic, flexible and less fearful behaviour. Humor helps to overcome negative experience. Humor can help the patient to gain new views towards the disease and a healthy distance towards occurring symptoms. Humor improves the relationship between patient and doctor. But beware: jokes can also be used to express fears, aggression or shame. Therefore it is worthwhile to listen carefully to what patients want to express. Humor reduces the risk of burnout. In contact with patients, it is important to give their humor room, to use it and respond to it, more than making jokes. Humor can be trained. Humor training and creation of a humorous atmosphere in health care facilities should also be supported by health insurance funds, institutions' sponsors and public authorities. © Georg Thieme Verlag KG Stuttgart · New York.

  6. Mecanismos de humor verbal en Twitter

    Full Text Available The present article aims to characterize samples of verbal humor published on the social network Twitter. To do so, an analysis of 81 humorous texts published under the hashtag #otegi during 1 March 2016, on which date Arnaldo Otegi was released from prison after six years, was carried out. A pragmatic study of the tweets was performed, opting for the General Theory of Verbal Humor as a basis. The examination conducted reveals that the manner of presentation of opposing scripts, the logical mechanisms availed of to resolve this kind of incongruity, the special narrative strategies selected and the linguistic choices made are determined at all times by the circumstances in which the texts are presented and the upper limit constraint of 140 characters per Twitter publication.

    Humor is a unique ability in human beings. Suls [A two-stage model for the appreciation of jokes and cartoons. In P. E. Goldstein & J. H. McGhee (Eds.), The psychology of humour. Theoretical perspectives and empirical issues. New York: Academic Press, 1972, pp. 81-100] proposed a two-stage model of humor: detection and resolution of incongruity. Incongruity is generated when a prediction is not confirmed in the final part of a story. To comprehend humor, it is necessary to revisit the story, transforming an incongruous situation into a funny, congruous one. Patient and neuroimaging studies carried out until now lead to different outcomes. In particular, patient studies found that right brain-lesion patients have difficulties in humor comprehension, whereas neuroimaging studies suggested a major involvement of the left hemisphere in both humor detection and comprehension. To prevent activation of the left hemisphere due to language processing, we devised a nonverbal task comprising cartoon pairs. Our findings demonstrate activation of both the left and the right hemispheres when comparing funny versus nonfunny cartoons. In particular, we found activation of the right inferior frontal gyrus (BA 47), the left superior temporal gyrus (BA 38), the left middle temporal gyrus (BA 21), and the left cerebellum. These areas were also activated in a nonverbal task exploring attribution of intention [Brunet, E., Sarfati, Y., Hardy-Bayle, M. C., & Decety, J. A PET investigation of the attribution of intentions with a nonverbal task. Neuroimage, 11, 157-166, 2000]. We hypothesize that the resolution of incongruity might occur through a process of intention attribution. We also asked subjects to rate the funniness of each cartoon pair. A parametric analysis showed that the left amygdala was activated in relation to subjective amusement. We hypothesize that the amygdala plays a key role in giving humor an emotional dimension.

    Full Text Available The main point of this work is to show how humor—when is used properly- has a positive effect on the patient ant the therapist’s self improving their alliance, supervision and team meetings. It’s also good for profesionals to include humor, recreation and rest in their job routines, because these ingredients let them be more effective in psychoterapy. The vast majority of psychological theories agree on its importance. The Cognitive Psychology believes that humor helps the patient evaluate reality in a different way, stops disfunctional thoughts, lets the expression of negative emotions and finds more adaptative patterns.

    The goal of this article is to expose different aspects of the use of humor in therapy. We hope that it will stimulate reflection and guide the clinician toward appropriate use of humorous interventions. Historical highlights of the topic will be presented. Then a practical definition of therapeutic humor and the main theories about humor will be reviewed. We will also discuss the probable mechanisms of action explaining the efficacy of humor in psychotherapy, as well as potential risks and benefits of its use. We will try to determine different factors influencing the patient's receptivity to humor. Subsequently, a classification of humor will be proposed, followed by a description of selected types of humor often used in therapy, with clinical cases as examples.

  11. Risky business: When humor increases and decreases status.

    Bitterly, T Bradford; Brooks, Alison Wood; Schweitzer, Maurice E

    2017-03-01

    Across 8 experiments, we demonstrate that humor can influence status, but attempting to use humor is risky. The successful use of humor can increase status in both new and existing relationships, but unsuccessful humor attempts (e.g., inappropriate jokes) can harm status. The relationship between the successful use of humor and status is mediated by perceptions of confidence and competence. The successful use of humor signals confidence and competence, which in turn increases the joke teller's status. Interestingly, telling both appropriate and inappropriate jokes, regardless of the outcome, signals confidence. Although signaling confidence typically increases status and power, telling inappropriate jokes signals low competence and the combined effect of high confidence and low competence harms status. Rather than conceptualizing humor as a frivolous or ancillary behavior, we argue that humor plays a fundamental role in shaping interpersonal perceptions and hierarchies within groups.

    Full Text Available Artrite reumatóide é uma doença difusa do tecido conjuntivo que se caracteriza pelo acometimento articular e sistêmico. Disfunções hematológicas como anemia ocorrem em até 65% dos pacientes, sendo a anemia das doenças crônicas a forma mais comum. A anemia hemolítica auto-imune pode estar associada à difusa do tecido conjuntivo, sendo classicamente associada ao lúpus eritematoso sistêmico e fazendo parte dos seus critérios de classificação. A presença de anemia hemolítica auto-imune em artrite reumatóide é relatada raramente na literatura e os mecanismos etiopatogênicos para o seu desenvolvimento ainda não estão esclarecidos. Descrevemos um caso de artrite reumatóide no adulto e outro de artrite reumatóide juvenil que desenvolveram anemia hemolítica auto-imune e discutimos os prováveis mecanismos etiopatogênicos envolvidos.Rheumatoid arthritis is a connective tissue disease characterized by articular and systemic involvement. Hematological abnormalities such as anemia may occur in up to 65% of the patients, with chronic disease anemia being the commonest form. Autoimmune hemolytic anemia can be associated with different connective tissue diseases, particularly systemic lupus erythematosus and it is part of its classification criteria. On the other hand, the presence of autoimmune hemolytic anemia in rheumatoid arthritis has rarely been described in the literature and the pathogenic mechanisms for its development remain unclear. We describe here a case of rheumatoid arthritis and another of juvenile rheumatoid arthritis that developed to autoimmune hemolytic anemia and present the probable etiopathogenic mechanisms.

    Full Text Available Several clinical and experimental studies have demonstrated gender dimorphism in immune and organ responsiveness and in the susceptibility to and morbidity from shock, trauma, and sepsis. In this respect, cell-mediated immune responses have been shown to be depressed in males following trauma-hemorrhage, whereas they were aintained/enhanced in proestrus females. Furthermore, sex hormones have been shown to be responsible for this gender-specific immune response following adverse circulatory conditions. More specifically, studies indicate that androgens produce immunodepression following trauma-hemorrhage in males. In contrast, female sex steroids appear to exhibit immunoprotective properties following trauma and severe blood loss. With regard to the underlying mechanisms, receptors for sex hormones have been identified on various immune cells suggesting direct effects of these hormones on the immune cells. Alternatively, indirect effects of sex hormones, ie, modulation of cardiovascular responses or androgen- and estrogen-synthesizing enzymes, might contribute to gender-specific immune responses. Recent studies indicate that sex hormones, eg, dehydroepiandrosterone (DHEA, also modulate the function of peripheral blood mononuclear cells in surgical patients. Thus, the immunomodulatory properties of sex hormones/receptor antagonists/sex steroid synthesizing enzymes following trauma-hemorrhage suggests novel therapeutic strategies for the treatment of immunodepression in surgical patients.Uma série de estudos clínicos e experimentais demonstram a existência de dimorfismo sexual das respostas imunológicas e orgânicas, bem como da suscetibilidade e morbidade em relação ao choque, ao trauma e à sepse.

The current experimental study addresses this gap by investigating how romantic motives (short-term or long-term affect individuals’ anticipated use of, and response to, positive humor and negative humor. Heterosexual participants (n = 224 imagined the pursuit of either a desired short-term or long-term relationship, indicated the extent to which they would produce positive and negative humor, and reported how their own interest would change in response to the imaginary target’s use of positive or negative humor. Results revealed that individuals are strategic in their humor production as a function of relational motives. Individuals produced positive humor in both contexts but limited their use of negative humor when pursuing a long-term relationship. The target’s positive humor increased individuals’ attraction, especially women’s, and although negative humor boosted attraction, it did not boost attraction more for short-term than long-term relationships. Findings extend a trait-indicator model of humor and their implications are discussed in light of other theoretical perspectives.

    The way individuals use humor to interact interpersonally has been associated with general personality, depression, and suicidality. Certain humor styles may moderate the risk for suicide ideation (SI) in individuals who are high in specific risk factors (e.g., thwarted belongingness, perceived burdensomeness). Previous research suggests a relationship between humor styles and borderline personality disorder (BPD) and an increased risk of suicidality and suicide completion in individuals with BPD. Participants (n =176) completed measures of BPD traits, SI, and humor styles. It was hypothesized that BPD traits would be positively correlated with negative humor styles and negatively correlated with positive humor styles, and that humor styles would significantly moderate BPD traits and SI. Results showed that BPD traits were negatively correlated with self-enhancing humor styles and positively correlated with self-defeating humor styles, but that they were not significantly correlated with affiliative or aggressive humor styles. Bootstrapping analyses demonstrated that the affiliative, self-enhancing, and self-defeating humor styles significantly moderated BPD traits and SI, while the aggressive humor style did not.

    To test whether appreciation of humor might be a non-motor function affected by Parkinson's disease (PD). Thirty-nine PD patients and 38 healthy controls participated in this study. Appreciation of humor and effect of the presentation method utilized were assessed. Sense of humor was evaluated by the sense of humor questionnaire (SHQ-6). Humor appreciation was tested using three methods of presentation: videos, audio sketches and pictorial cartoons, each portraying both obvious and non-obvious humor content. Depression, anxiety, cognition, disease severity and quality of life were measured by standardized questionnaires and correlated with humor outcomes. Patients with PD rated humor content lower than controls on every method of presentation as well as on the SHQ-6 (p = 0.004). The greatest between-group difference was noted when the material was presented visually via pictorial cartoons (p < 0.0001). In addition, obvious humor content was rated higher than non-obvious content by the PD group in all three presentation methods (p < 0.05). The degree of depression and anxiety did not influence these results. Patients with PD have a decreased sense of humor compared to healthy controls. Utilizing audio methods of presentation and humor in an obvious mode appears to be the preferred approach for eliciting responses to humor in a PD population. Copyright © 2011 Elsevier Ltd.

    Full Text Available Background: The central goal of palliative care is to optimize the quality of life of patients suffering from life-limiting illnesses, which includes psychosocial and spiritual wellbeing. Research has demonstrated positive correlations between humor and laughter with life satisfaction and other aspects of wellbeing, and physiological symptoms can be improved by humorous stimuli.Objectives: The aim of this review is to evaluate humor interventions and assessments that have been applied in palliative care and to derive implications for future research.Methods: A systematic review of four databases identified 13 included studies. Criteria for inclusion were peer-reviewed English-language studies on humor interventions or assessments in a palliative care context.Results: Two studies on humor interventions and 11 studies on humor assessment were included in the systematic review. Most of these studies were about the patients' perspective on humor in palliative care. Findings showed that humor had a positive effect on patients, their relatives, and professional caregivers. Humor was widely perceived as appropriate and seen as beneficial to care in all studies.Conclusions: Even though humor interventions seem to be potentially useful in palliative care, descriptions evaluating their use are scarce. Overall, research on humor assessment and interventions in palliative care has remained limited in terms of quantity and quality. More research activities are needed to build a solid empirical foundation for implementing humor and laughter as part of regular palliative care activities.

    Much of what we think we know about the performance of humor relies on our intuitions about prosody (e.g., "it's all about timing"); however, this has never been empirically tested. Thus, the central question addressed in this article is whether speakers mark punch lines in jokes prosodically and, if so, how. To answer this question,…

    2006-01-01

    Full Text Available Articles in both the lay and professional literature have extolled the virtues of humor, many giving the impression that the health benefits of humor are well documented by the scientific and medical community. The concept that humor or laughter can be therapeutic goes back to biblical times and this belief has received varying levels of support from the scientific community at different points in its history. Current research indicates that using humor is well accepted by the public and is frequently used as a coping mechanism. However, the scientific evidence of the benefits of using humor on various health related outcomes still leaves many questions unanswered.

    1990-02-01

    The benefits of humor in reducing anxiety were investigated in a laboratory study, in which subjects were falsely led to believe that they would receive a shock in 12 min. Participants were 53 undergraduate students with either high or low sense of humor as measured by the Situational Humor Response Questionnaire of Martin and Lefcourt (1984). During the anticipatory period, subjects listened to either a humorous tape, a nonhumorous tape, or no tape. Dependent variables were repeated measures of self-reported anxiety, heart rate, and zygomatic facial activity. Anxiety increased over the anticipatory period, as predicted. A significant interaction between condition and time indicated that subjects from the humor condition consistently rated themselves as less anxious and reported less increase in stress as the shock approached. A three-way interaction concentrating on the final 3 min. indicated a tendency for subjects with low sense of humor to have higher heart rates in the no-tape condition than in the humorous or nonhumorous tape conditions. Analysis for zygomatic activity indicated more smiling by subjects with high sense of humor and by subjects in the humor condition. Also, the humorous tape elicited more smiling by subjects with high sense of humor.

    This study assessed the concurrent and prospective (fall to spring) associations between four different humor styles to assess the degree to which stable friendships are characterized by similarity, and to assess whether best friends' humor styles influence each other's later use of humor. Participants were aged 11-13 years, with 87 stable, reciprocal best friend dyads. Self-report assessments of humor styles were completed on both occasions. Results indicated that there was no initial similarity in dyads' levels of humor. However, dyads' use of humor that enhances interpersonal relationships (Affiliative humor) became positively correlated by spring. Additionally, young people's use of this humor style was positively associated with their best friend's later use of the same. No such effects were present for humor which was aggressive, denigrating toward the self, or used to enhance the self. These results have clear implications for theories of humor style development, highlighting an important role for Affiliative humor within stable friendship dyads. Copyright © 2015 The Authors.

    Full Text Available Literary historian Petar Kolendić (1882–1969 published two tributes to Šimun Kožičić: Zadranin Šimun Kožičić i njegova štamparija na Reci (Šimun Kožičić from Zadar and his Printing House in Rijeka and Najstariji naš bukvar (Our Oldest Elementary Reader. Both were published in: Južni pregled (Southern Review, year IX, Skoplje 1934, pp 61¬71; 198¬201. In the first tribute, the author presented in brief Kožičić’s life. He recorded that Kožičić, with many bishops “from our parts”, arrived to Rome in 1512, when the (ecumenical Fifth Council of the Lateran was held “with the main aim to create a frame of mind against the Turks”, with the intention to offer necessary information in person. In the first session held on 10 May 1512, Kožičić had the opportunity to hear Bernardin Zane, the Archbishop of Split, address this matter; consequently, he held his own first speech at the Council on 27 April 1513. He held his second speech – according to Kolendić’s words – “probably in agreement with Prince Bernardin Frankopan” in the autumn, on 5 November 1516, outside the Council session, before Pope Leo X and his cardinals. Kolendić states that no typographic note accompanied the publications of both Kožičić’s speeches, but that they took place “with surety in Rome”. Well¬known facts are that Kožičić was forced to leave Modruš, that he barely managed to escape from the Turks, that he stayed in Vinodol, and that, around 1529, he withdrew to Rijeka where he opened his Glagolitic Printing House. He travelled to Venice to acquire printing inventory for his Printing House. Kolendić establishes which xylographs and letters Kožičić acquired there, and shows that Kožičić’s letters differ from the Glagolitic letters produced by Andrea Torresani or the Printing House Francesco Bindoni et Maffeo Pasini, who had before Kožičić published the Glagolitic Breviary (1493, Elementary Reader (1527 and

  2. Mathematics and Humor: John Allen Paulos and the Numeracy Crusade

    2015-07-01

    Full Text Available John Allen Paulos at minimum gave the Numeracy movement a name through his book Innumeracy: Mathematical Illiteracy and Its Consequences. What may not be so obvious was Paulos’ strong interest in the relationship between mathematics and mathematicians on the one hand and humor and stand-up-comedian joke structures on the other. Innumeracy itself could be seen as a typically mathematical Gotcha joke on American culture generally. In this perspective, a Minnesotan acculturated to Minnesota-Nice Humor of Self-Immolation Proclivities (SImP looks at the more raw-boned, take-no-prisoners humor style Paulos outlined in Mathematics and Humor and implemented in Innumeracy. Despite the difference in humor styles, there is much to applaud in Paulos’ analysis of the relationship between certain types of humor and professional interests of mathematicians in Mathematics and Humor. Much humor relies on the sense of incongruity which Paulos’ claims to be central to all humor and key to mathematical reductio ad absurdum. Mathematics is rightfully famous for a sense of combinatorial playfulness in its most elegant proofs, as humor often relies on clashing combinations of word play. And a great range of mathematical lore is best understood within a concept of a sudden drop from one sense of certainty to another (essentially a Gotcha on the audience. Innumeracy repeatedly exemplifies Gotchas on the great unwashed and unmathematical majority. Extensive empirical evidence over the last quarter century allows us to synthesize these Paulos observations into the idea that inculcated mathematical humor has strong propensities to complex Intellectual, Advocate, and Crusader humor forms. However, the Paulos humors do not include the Sympathetic Pain humor form, the inclusion of which may increase teaching effectiveness.

    Full Text Available For almost four decades, ESL/EFL scholars have been trying to find which learning type, contextualized vs. decontextualized, leads to better vocabulary acquisition and retention. In an attempt to solve this problem, this study tried to examine the possible effectiveness of using humorous context on vocabulary acquisition and retention. Another issue that was undertaken in the present study was comparing the efficiency of contextualized and decontextualized vocabulary learning and retention. For this purpose, 58 Iranian EFL learners were categorized into 3 groups: a humorous, b non-humorous, and c decontextualized. The findings were analyzed using one-way ANOVA and Tukey post hoc test. As the results revealed, the participants in decontextualized group outperformed the participants in both humorous and non-humorous groups. However, it should be noted that the performance of humorous group was significantly better than the performance of non-humorous group.

  5. Experimental sepsis impairs humoral memory in mice.

    Directory of Open Access Journals (Sweden)

    Christian Pötschke

    Full Text Available Patients with sepsis are often immune suppressed, and experimental mouse models of sepsis also display this feature. However, acute sepsis in mice is also characterized by a generalized B cell activation and plasma cell differentiation, resulting in a marked increase in serum antibody concentration. Its effects on humoral memory are not clearly defined. We measured the effects of experimental sepsis on long-term immunological memory for a defined antigen: we induced colon ascendens stent peritonitis (CASP 8 weeks after 2 rounds of immunization with ovalbumin. Four weeks later, the antigen-specific bone marrow plasma cell count had doubled in immunized non-septic animals, but remained unchanged in immunized septic animals. Sepsis also caused a decrease in antigen-specific serum antibody concentration. We conclude that sepsis weakens humoral memory by impeding the antigen-specific plasma cell pool's development, which is not complete 8 weeks after secondary immunization.

  6. Can the use of humor in psychotherapy be taught?

    Valentine, Lisa; Gabbard, Glen O

    2014-02-01

    Despite an abundance of literature detailing the potential benefits of the use of humor in therapy, humor is rarely taught to psychiatric residents as a method of therapeutic intervention. This communication attempts to explain how current understanding of attachment theory and neuroscience may assist psychiatric faculty and supervisors in their teaching of humorous therapeutic interventions. This article reviews and synthesizes the extant literature on the use of humor, as well as recent work in neuroscience, attachment theory, and mentalization. Humor can be conceptualized as an instance of implicit relational knowing and may thus contribute significantly to the therapeutic action of psychotherapy as a subcategory of "moments of meeting" between therapist and patient. However, training residents to use humor in psychotherapy requires more individualized attention in supervision and classroom seminars. Factors such as individual proclivities for humorous repartee, mentalizing capacity, and an authentic interest in adding humor to the session may be necessary to incorporate spontaneous humor into one's technique. New findings from the areas of attachment theory, neuroscience, and right-hemisphere learning are providing potential opportunities for sophisticated teaching of the use of humor in psychotherapy.

    Little is known about humor's use in clinical encounters, despite its many potential benefits. We aimed to describe humor during clinical encounters. We analyzed 112 recorded clinical encounters. Two reviewers working independently identified instances of humor, as well as information surrounding the logistics of its use. Of the 112 encounters, 66 (59%) contained 131 instances of humor. Humor was similarly frequent in primary care (36/61, 59%) and in specialty care (30/51, 59%), was more common in gender-concordant interactions (43/63, 68%), and was most common during counseling (81/112, 62%). Patients and clinicians introduced humor similarly (63 vs 66 instances). Typically, humor was about the patient's medical condition (40/131, 31%). Humor is used commonly during counseling to discuss the patient's medical condition and to relate to general life events bringing warmth to the medical encounter. The timing and topic of humor and its use by all parties suggests humor plays a role in the social connection between patients and physicians and allows easier discussion of difficult topics. Further research is necessary to establish its impact on clinicians, patients, and outcomes. © Copyright 2018 by the American Board of Family Medicine.

  8. The evolution of humor from male aggression

    Full Text Available Sam ShusterNewcastle University, Newcastle Upon Type, NE1 7RU, UKAbstract: The response to seeing a man riding a unicycle was reported to be consistently related to the viewer's sex and stage of physical development. To see if this observation was universal, observations of responses were collected from 23 male and 9 female unicyclists aged 15–69 years, with 2–40 years cycling experience across four continents. With two exceptions among men, the findings were the same as those originally reported: children showed interest and curiosity, young girls showed little interest, while adult women showed a kindly, concerned, praising response. By contrast, boys showed physical aggression, which became more verbal, merging in the later teens to the snide, aggressive, stereotyped humorous response shown by adult males, which became less frequent in elderly men. The universality of the response across different individuals, environments, and dates of observation suggests an endogenous mechanism, and the association with masculine development relates this to androgen. The theoretical consequences are discussed. It is concluded that humor develops from aggression in males and is evolutionarily related to sexual selection.Keywords: humor evolution, male aggressive behavior

  9. Who Benefits From Humor-Based Positive Psychology Interventions? The Moderating Effects of Personality Traits and Sense of Humor.

    2018-01-01

    The evidence for the effectiveness of humor-based positive psychology interventions (PPIs; i.e., interventions aimed at enhancing happiness and lowering depressive symptoms) is steadily increasing. However, little is known about who benefits most from them. We aim at narrowing this gap by examining whether personality traits and sense of humor moderate the long-term effects of humor-based interventions on happiness and depressive symptoms. We conducted two placebo-controlled online-intervention studies testing for moderation effects. In Study 1 ( N = 104) we tested for moderation effects of basic personality traits (i.e., psychoticism, extraversion, and neuroticism) in the three funny things intervention, a humor-based PPI. In Study 2 ( N = 632) we tested for moderation effects of the sense of humor in five different humor-based interventions. Happiness and depressive symptoms were assessed before and after the intervention, as well as after 1, 3, and 6 months. In Study 2, we assessed sense of humor before and 1 month after the intervention to investigate if changes in sense of humor go along with changes in happiness and depressive symptoms. We found moderating effects only for extraversion. Extraverts benefitted more from the three funny things intervention than introverts. For neuroticism and psychoticism no moderation effects were found. For sense of humor, no moderating effects were found for the effectiveness of the five humor-based interventions tested in Study 2. However, changes in sense of humor from pretest to the 1-month follow-up predicted changes in happiness and depressive symptoms. Taking a closer look, the playful attitude- and sense of humor-subscales predicted changes in happiness and depression for up to 6 months. Overall, moderating effects for personality (i.e., extraversion) were found, but none for sense of humor at baseline. However, increases in sense of humor during and after the intervention were associated with the interventions

Baseado no fato de que o rituximab reage especificamente contra o antígeno CD 20, induzindo depleção de células B e conseqüentemente levando à diminuição na produção de auto-anticorpos, cinco pacientes com citopenias auto-imunes foram tratados com esta droga. Os pacientes eram refratários à terapia convencional e receberam 375 mg/m² de rituximab semanalmente, por um período de quatro semanas. Todos os pacientes apresentaram melhora, seja pelo aumento do número de células (níveis de hemoglobina ou contagem de plaquetas, seja pela suspensão do uso de corticoesteróides. Não foram observadas reações importantes durante infusão do medicamento, ou mesmo episódios de infecção durante acompanhamento subseqüente. Desta forma, o rituximab se mostrou eficaz e seguro para pacientes portadores de anemia hemolítica e púrpura trombocitopênica de etiologia imunológica, sugerindo que esta droga deva fazer parte do arsenal terapêutico utilizado nestas doenças auto-imunes.The morbidity associated with the treatment of autoimmune cytopenias has created a need for new approaches. Based on the fact that rituximab reacts specifically against the CD 20 antigen and induces B-cell depletion interfering with the production of auto-antibodies, five patients with autoimmune cytopenias were treated. All patients were previously refractory to conventional therapy and received 375 mg/m² of rituximab infusion weekly, for four weeks. All patients improved either by increasing the number of cells or by being able to reach steroid suspension. No major reactions occurred during infusion, and no major infections occurred during the follow up. Rituximab appears to be active and safe for patients with autoimmune hemolytic anemia and thrombocytopenia, suggesting that this agent can play an important part in the therapeutic arsenal for

Quantitative proteome analysis of the aqueous humor by hyper reaction monitoring mass spectrometry (HRM-MS based on SWATH technology was performed.Expression levels of 87 proteins were found to be different between glaucomatous and control aqueous humor. Of the 87 proteins, 34 were significantly upregulated, whereas 53 proteins were downregulated in the aqueous humor from glaucoma patients compared to controls. Differentially expressed proteins were found to be involved in cholesterol-related, inflammatory, metabolic, antioxidant as well as proteolysis-related processes.Glaucoma leads to profound changes to the aqueous humor proteome consistent with an altered metabolic state, an inflammatory response and impaired antioxidant defense.

    Full Text Available The purpose of this study was to examine the role of humor style and motor skills in vulnerability to bullying. 729 adults responded to the Humor Style Questionnaire (HSQ and items retrospectively addressing their motor skills and bullying experiences during childhood. Consistent with recent research, poorer motor skills were associated with a greater extent of having been bullied. An association between stronger motor skills and affiliative humor was found, lending support to a shared biological basis theory underlying social and motor competency processes. Most importantly, being bullied was associated with higher self-defeating humor and lower affiliative humor. This supports earlier theoretical work by Klein and Kuiper (2006 and highlights the role that humor styles play in social interactions that can promote positive peer acceptance and wellbeing.

Their capacity to develop humoral immune responses to experimentally given thymus-dependent and thymus-independent antigens under various conditions is compared. Furthermore, experiments employing thymus transplantation and thymic humoral factors which are directed at the restoration of the diminished T cell functions in old age are reported. (Auth.)

    Humor is a complex behavior which includes cognitive, affective and motor responses. Based on observations of affective changes in patients with cerebellar lesions, the cerebellum may support cerebral and brainstem areas involved in understanding and appreciation of humorous stimuli and expression of laughter. The aim of the present study was to examine if humor appreciation, perception of humorous stimuli, and the succeeding facial reaction differ between patients with cerebellar degeneration and healthy controls. Twenty-three adults with pure cerebellar degeneration were compared with 23 age-, gender-, and education-matched healthy control subjects. No significant difference in humor appreciation and perception of humorous stimuli could be found between groups using the 3 Witz-Dimensionen Test, a validated test asking for funniness and aversiveness of jokes and cartoons. Furthermore, while observing jokes, humorous cartoons, and video sketches, facial expressions of subjects were videotaped and afterwards analysed using the Facial Action Coding System. Using depression as a covariate, the number, and to a lesser degree, the duration of facial expressions during laughter were reduced in cerebellar patients compared to healthy controls. In sum, appreciation of humor appears to be largely preserved in patients with chronic cerebellar degeneration. Cerebellar circuits may contribute to the expression of laughter. Findings add to the literature that non-motor disorders in patients with chronic cerebellar disease are generally mild, but do not exclude that more marked disorders may show up in acute cerebellar disease and/or in more specific tests of humor appreciation.

  19. Trait humor and longevity: do comics have the last laugh?

    1992-01-01

    Four sets of biographical data were analyzed in order to test the hypothesis that the ability to generate humor is associated with longevity. Although steps were taken to ensure that tests had high levels of statistical power, analyses provided very little support for the idea that individuals with a well-developed sense of humor live longer than serious writers and other entertainers. In addition, a subsidiary analysis revealed that those in the business of entertaining others died at an earlier age than those in other lines of endeavor. These findings suggest that researchers should turn their attention from trait humor to the effects of humorous material.

    Humor training has been applied to educational and clinical cases and has been found to be effective, but humor training for individuals with autism is relatively rare. The present study proposed a humor-knowledge and humor-skill training workshop to enhance the humor comprehension and appreciation of individuals with autism and examined the effects of the training. Participants were 20 adolescents with autism and average intelligence (above 70 in WAIS-III). They were randomly divided into experimental and control groups. Both questionnaire of joke comprehension and appreciation and a humor style questionnaire were used as instruments. The results supported the effectiveness of the 15-h training. The comprehension and appreciation of nonsense humor were significantly increased in the experimental group in comparison with the control group, although the incongruity-resolution jokes remained difficult to comprehend. The tendency to use affiliative humor was greater among individuals with autism in the experimental group, suggesting that the appreciation of humor can be learned.

    Although a series of reports on corneal fungal infection have been published, studies on pathogenic mechanisms and inflammation-associated cytokines remain limited. In this study, aqueous humor samples from fungal keratitis patients were collected to examine cytokine patterns and cellular profile for the pathogenesis of fungal keratitis. The aqueous humor samples were collected from ten patients with advanced stage fungal keratitis. Eight aqueous humor samples from patients with keratoconus or corneal dystrophy were taken as control. Approximately 100 μl to 300 μl of aqueous humor in each case were obtained for examination. The aqueous humor samples were centrifuged and the cells were stained and examined under optical microscope. Bacterial and fungal cultures were performed on the aqueous humor and corneal buttons of all patients. Cytokines related to inflammation including IL-1β, IL-6, IL-8, IL-10, TNF-α, and IFN-γ were examined using multiplex bead-based Luminex liquid protein array systems. Fungus infection was confirmed in these ten patients by smear stains and/or fungal cultures. Bacterial and fungal cultures revealed negative results in all aqueous humor specimens. Polymorphonuclear leukocytes were the predominant infiltrating cells in the aqueous humor of fungal keratitis. At the advanced stages of fungal keratitis, the levels of IL-1β, IL-6, IL-8, and IFN-γ in the aqueous humor were significantly increased when compared with control (phumor was associated with fungal keratitis.

    According to research literature, humor inside the staff-patient interaction seems to be significant in the area of forensic mental healthcare. However, existing literature on the subject is limited. Therefore, the aim of this study was to explore the characteristics of the use humor by forensic mental health staff members in interactions with forensic mental health inpatients. The study included 32 forensic mental health staff members, used 307 hours of participant observations, 48 informal interviews, and seven formal semistructured interviews. Outcomes identify four themes concerning the conveyance of power to, from, and between forensic mental health staff and patients as they interact: (a) "the informal use: the human-to-human approach," characterized by an informal use of humor and without any reference to mental health issues; (b) the "formal use of humor: the staff-patient approach," characterized as formal with a view on the patient as mentally ill, unable to understand humor, and with the aim of using humor to prevent conflicts or negative behavior; (c) "protest against requested care: the human-patient approach," characterized by the use of humor as a protest against requested care; and the use of (d) "inadequacy humor: the staff-human approach," characterized by the use of inadequacy-humor referring to, for example, patients' physical features. Recommendations and clinical implications are discussed.

    Full Text Available The study reported in this paper aims to analyze the possible strategies used in the subtitling of the first five episodes (season 1 of Friends to render the episodes’ humorous dialogues. It examines the subtitler’s strategies in preserving both the semantic and humorous genes of laughter intended by the original humor. The analysis takes into account the internal and external structures of humors both in the target and source language. Choosing a subtitling strategy involves a decisionmaking process where the internal and external factors come into play and, therefore, rendering humors in a contextually bound medium, such as subtitling, does not necessarily work in the TL environment in a consistent manner. The inconsistency highlights the fact that humors, even those considered universal, are not digested in the same manner across cultures.

A vacina para hepatite B (HB, quando aplicada por via intramuscular (IM em pacientes com insuficiência renal crônica fase V, frequentemente não induz produção adequada de anticorpos. A injeção intradérmica (ID foi sugerida como sendo o método de inoculação mais eficiente. OBJETIVO: Comparar a resposta imune à injeção IM ou ID da vacina em indivíduos em HD. PACIENTES E MÉTODOS: Trinta e um pacientes incidentes em HD foram randomizados alternativamente para vacinação contra HB via IM ou ID. Dezesseis foram designados aleatoriamente para receber vacina IM (40 mg/dose e 15 ID (4mg /dose. Os níveis de anticorpos de superfície do vírus da hepatite B, parâmetros hematimétricos, ureia sérica, e Kt/V foram avaliados mensalmente. Proteína-C reativa, paratormônio, ferritina, aminotransferases e albumina foram avaliados antes da inoculação inicial e seis meses após a mesma. RESULTADOS: Os níveis de uréia foram maiores no grupo ID (P(1 = 0,031; os níveis de ferritina foram mais elevados no IM (P(2 = 0,037. Houve tendência a aumento nos níveis de proteína C reativa no grupo ID. A avaliação do Comitê de Monitoramento de Segurança dos indivíduos expostos recomendou a suspensão do estudo já que a inoculação por via IM converteu 62,5% e a ID converteu apenas 13,3% dos pacientes expostos. CONCLUSÃO: Com a metodologia utilizada, os resultados da vacina contra HB aplicada por via ID foi inferior à inoculação IM. Tais resultados podem ser decorrentes das doses inoculadas ou de outros fatores, como inflamação.

  5. Hippocrates' humoral pathology in nowaday's reflections.

    Ancient medicine integrated three components: experience (empirical observation), religion/magic and speculations of natural philosophers. The Greek medicine out-achieved medicine of other ancient nations in starting to investigate the true causes of health and diseases and thus laying foundations for the diagnosis, prognosis and treatment. Hippocrates, the most famous physician of the ancient times, made a synthesis of existing philosophical opinions from the point of view of a physician. His 58 writings were preserved in the collection "Corpus Hippocraticum". The most relevant writing in it--"Peri fyseos anthropu" (On the nature of man)--is ascribed to Hippocrates' son-in-law Polybos to whom we are grateful for the ancient humoral-pathological theory. In explaining human organism and its processes the author integrated ancient teachings on 4 basic humors (humoral theory), elements and qualities with observations of manifestations of health and disease. Normal condition (health) was defined as balance between the body fluids (eukrasia) and external environment. If this balance is disturbed, the result is dyskrasia, i.e. disease studied by pathology. According to Hippocrates disease causes can be understood only through empirical study. A man has a power to overcome disease, but to achieve it the right diet is necessary to keep harmony in body fluids of an organism. The role of a physician was just to support the nature. "Prognosis", another writing included in "Corpus Hippocraticum", reflects Hippocrates' understanding of prognosis as a necessary development of diagnosis based on past knowledge (anamnesis) and present observation. Ideas of Hippocrates and his medical school are still valuable and inspiring especially for today's very sophisticated medicine--concept of fighting diseases by natural means: maintaining healthy lifestyle and harmony within the organism, or an effort for perfect understanding of human creature and for humanization of medicine.

    Recently, two forms of virtue-related humor, benevolent and corrective, have been introduced. Benevolent humor treats human weaknesses and wrongdoings benevolently, while corrective humor aims at correcting and bettering them. Twelve marker items for benevolent and corrective humor (the BenCor) were developed, and it was demonstrated that they fill the gap between humor as temperament and virtue. The present study investigates responses to the BenCor from 25 samples in 22 countries (overall N = 7,226). The psychometric properties of the BenCor were found to be sufficient in most of the samples, including internal consistency, unidimensionality, and factorial validity. Importantly, benevolent and corrective humor were clearly established as two positively related, yet distinct dimensions of virtue-related humor. Metric measurement invariance was supported across the 25 samples, and scalar invariance was supported across six age groups (from 18 to 50+ years) and across gender. Comparisons of samples within and between four countries (Malaysia, Switzerland, Turkey, and the UK) showed that the item profiles were more similar within than between countries, though some evidence for regional differences was also found. This study thus supported, for the first time, the suitability of the 12 marker items of benevolent and corrective humor in different countries, enabling a cumulative cross-cultural research and eventually applications of humor aiming at the good.

  9. The evolution of humor from male aggression.

    Shuster, Sam

    2012-01-01

    The response to seeing a man riding a unicycle was reported to be consistently related to the viewer's sex and stage of physical development. To see if this observation was universal, observations of responses were collected from 23 male and 9 female unicyclists aged 15-69 years, with 2-40 years cycling experience across four continents. With two exceptions among men, the findings were the same as those originally reported: children showed interest and curiosity, young girls showed little interest, while adult women showed a kindly, concerned, praising response. By contrast, boys showed physical aggression, which became more verbal, merging in the later teens to the snide, aggressive, stereotyped humorous response shown by adult males, which became less frequent in elderly men. The universality of the response across different individuals, environments, and dates of observation suggests an endogenous mechanism, and the association with masculine development relates this to androgen. The theoretical consequences are discussed. It is concluded that humor develops from aggression in males and is evolutionarily related to sexual selection.

  10. Sildenafil Stimulates Aqueous Humor Turnover in Rabbits

    Sildenafil citrate increases ocular blood flow and accelerates the rate of anterior chamber refilling after paracentesis. The latter effect could have resulted from a reduction in outflow facility or from an increase in aqueous humor (AH) production. In this study, we used scanning ocular fluorophotometry to examine the effects of sildenafil on AH turnover, and thus, AH production in eyes of live normal rabbits. For this, the rate of aqueous humor flow (AHF) was quantified with a commercially available fluorophotometer that measured the rate of fluorescein clearance from the anterior segment, which predominantly occurs via the trabecular meshwork. After ≈ 2 hrs of control scans to determine the baseline rate of AHF, the rabbits were fed 33 mg of sildenafil and allowed ≈ 45 min for the drug to enter the systemic circulation. Thereafter, fluorescence scans were retaken for an additional 90–120 min. Sildenafil ingestion increased AHF by about 36%, from 2.31 μL/min to 3.14 μL/min (PViagra, Revatio), stimulates AHF in rabbits. Our results seem consistent with reports indicating that the drug dilates intraocular arteries and augments intraocular vascular flow. These physiological responses to the agent apparently led to increased fluid entry into the anterior chamber. As such, the drug might have utility in patients with ocular hypotony resulting from insufficient AH formation. PMID:23562660

I shall explore children’s acquisition of the communicative contexts that constitute the background enabling them to perform humorous interactions before being able to analyze them in the terms allowed by a full fledged ToM. I consider that different forms of humor share a number of basic features and that we can draw a continuum from simple forms to sophisticated ones. In particular I shall focus on teasing, a form of humor already present in preverbal infants but also considered as a typical feature of irony. I shall argue that all forms of humor can be described in the terms of a kind of interaction that I propose to call playing with expectations.

    Full Text Available Objective: The provision of information appears to be an important feature of humor. The present studies examined whether humor serves as an interpersonal signal such that an individual's style of humor is associated with how the individual is perceived by others. Method: We examined this issue across two studies. In Study 1, undergraduate participants (257 targets were rated more positively by their friends and family members (1194 perceivers when they possessed more benign humor styles. In Study 2, 1190 community participants rated the romantic desirability of targets ostensibly possessing different humor styles. Results: Across both studies, our results were consistent with the possibility that humor serves as a signal. More specifically, individuals with benign humor styles (affiliative and self-enhancing humor styles were evaluated more positively than those targets with injurious humor styles (aggressive and self-defeating humor styles. Conclusion: These findings are discussed in terms of the role that humor may play in interpersonal perception and relationships.

Embora esse tópico tenha sido muito debatido na literatura dos últimos 10 anos, a percepção é de que uma porcentagem significativa de casos continuam sendo subdiagnosticados devido à utilização dos mesmos critérios independente da faixa etária. Os diversos estudos epidemiológicos realizados na população infantil fundamentam-se nesses critérios para cálculos de prevalência, o que tornam duvidosos os números atualmente publicados. Embora a neurociência tenha alcançado grandes avanços no conhecimento dessas patologias, ainda é necessário um melhor entendimento sobre como os fatores genéticos e ambientais interagem e influenciam a origem, gravidade e resposta ao tratamento. CONCLUSÕES: Os transtornos do humor são patologias de alta prevalência na infância e adolescência, com grande impacto na vida dos portadores no longo prazo. Constatamos a necessidade de aprimorar os critérios diagnósticos, adequando-os à população infantil, com objetivo de facilitar ao clínico, particularmente ao pediatra, diagnóstico e intervenção precoce.

    Aqueous humor dynamics was observed in patients treated for glaucoma. Aqueous flow was measured using the radionuclide method of contact application of 22 NaCl and the detection of gamma radiation with external detectors. The sample of 184 eyes was divided into three groups: open-angle glaucoma with therapy, open-angle glaucoma without therapy and angle-closure glaucoma 47 eyes were used as controls.

    The transformation of all things media and information into a dynamic environment of user access has created what seems infinite possibilities to inform the public in many different ways - as well as seemingly infinite possibilities to confuse. This talk will describe a rather non-conventional collaboration between two different creative cultures and its significance to maintaining scientific accuracy and devising strategies important to audience engagement - among them, humor. While focusing on the award-winning effort ``When Things Get Small'' created by University of California Television producer R. Wargo in collaboration with condensed matter physicist I.K. Schuller and actor Adam J. Smith, with both NSF and private support, the case study provides insight into a model and modes which can be used successfully by other scientists to engage the public in what they do.

    The aim of the paper is to present the Polish adaptation of the Humor Climate Questionnaire (HCQ), designed to measure humor as organizational climate feature. The authors employed back-translation and independent judges method to choose the best version of the translated items. The psychometric properties of HCQ were estimated on the basis of 2 samples: the basic group of employees (N = 217) and the group of employees who had completed the survey twice (N = 55). The results of statistical analyses proved that HCQ is a reliable tool. Explorative Factor Analysis supported the 4-factor structure of the original method's theoretical model. The validity of the subscales is high, Cronbach's α varied from 0.8 to 0.9. The directions and values of intercorrelations between subscales were similar to those of the English version. The Humor Climate Questionnaire is a relatively time-stable tool (r = 0.44-0.74). Polish adaptation is reliable and applicable for cross-sectional studies. The obtained results are comparable to the characteristics of the original version. However, the results of factor analysis show that the data do not fully fit the theoretical model.

    Full Text Available A escala instrumento de medida de atitude empreendedora (Imae, desenvolvida por Souza e Lopes Jr. (2005, contém duas dimensões: prospecção e inovação, e gestão e persistência. Com a finalidade de verificar a validade e o intervalo em que propicia a medida de atitude empreendedora, além de investigar sua capacidade de discriminar a resposta que o indivíduo está apto a dar, o objetivo deste artigo é validar a escala Imae por meio do modelo de resposta gradual da teoria da resposta ao item (TRI, que revolucionou a teoria de medidas. A TRI, construtos da psicologia utilizados em estudos de discriminação de respostas, em especial em grandes amostras de respondentes a um determinado fenômeno, é constituída de modelos matemáticos que relacionam um ou mais traços latentes (não observados de um indivíduo com a probabilidade de este dar uma determinada resposta a um item. O ponto crucial da TRI é que ela leva em consideração o item particularmente, sem relevar os escores totais, portanto as conclusões não dependem apenas do teste ou questionário, mas de cada elemento que o compõe. Os principais resultados encontrados foram a identificação de dois níveis da escala, denominados âncoras, que permitem interpretar tendências de pessoas com atitude empreendedora e a constatação de que os itens da escala Imae apresentam boa capacidade de discriminar a resposta que o indivíduo está apto a dar, o que confere qualidade aos itens e, portanto, à escala. A importância deste estudo reside no papel fundamental que a atitude desempenha nas escolhas que as pessoas fazem em relação à própria vida, de modo a ajudá-las a determinar seus próprios atos.

    Abstract The study aimed to explore the humor processing elicited through the manipulation of artistic drawings. Using the Comprehension–Elaboration Theory of humor as the main research background, the experiment manipulated the head portraits of celebrities based on the independent variables of facial deformation (large/small) and addition of affective features (positive/negative). A 64-channel electroencephalography was recorded in 30 participants while viewing the incongruous drawings of celebrities. The electroencephalography temporal and spectral responses were measured during the three stages of humor which included incongruity detection, incongruity comprehension and elaboration of humor. Analysis of event-related potentials indicated that for humorous vs non-humorous drawings, facial deformation and the addition of affective features significantly affected the degree of humor elicited, specifically: large > small deformation; negative > positive affective features. The N170, N270, N400, N600-800 and N900-1200 components showed significant differences, particularly in the right prefrontal and frontal regions. Analysis of event-related spectral perturbation showed significant differences in the theta band evoked in the anterior cingulate cortex, parietal region and posterior cingulate cortex; and in the alpha and beta bands in the motor areas. These regions are involved in emotional processing, memory retrieval, and laughter and feelings of amusement induced by elaboration of the situation. PMID:28402573

    Full Text Available Although there are many clinical programs designed to bring humor into pediatric hospitals, there has been very little research with children or adolescents concerning the specific utility of humor for children undergoing stressful or painful procedures. Rx Laughter™, a non-profit organization interested in the use of humor for healing, collaborated with UCLA to collect preliminary data on a sample of 18 children aged 7–16 years. Participants watched humorous video-tapes before, during and after a standardized pain task that involved placing a hand in cold water. Pain appraisal (ratings of pain severity and pain tolerance (submersion time were recorded and examined in relation to humor indicators (number of laughs/smiles during each video and child ratings of how funny the video was. Whereas humor indicators were not significantly associated with pain appraisal or tolerance, the group demonstrated significantly greater pain tolerance while viewing funny videos than when viewing the videos immediately before or after the cold-water task. The results suggest that humorous distraction is useful to help children and adolescents tolerate painful procedures. Further study is indicated to explore the specific mechanism of this benefit.

    It has been proposed that four main styles of humor exist, two which are thought to be adaptive (affiliative, self-enhancing) and two which are thought to be maladaptive (aggressive, self-defeating). Whilst the existence of these four humor styles has been supported in older children, it is suggested that for younger children, self-enhancing and self-defeating humor may develop at a later point. To investigate this further, the current research involved five semi-structured paired interviews with children aged eight to eleven years to explore the use and understanding of self-enhancing and self-defeating humor in this age group. Findings indicated that use of both self-enhancing and self-defeating humor were apparent in some children, but not all. It therefore seems appropriate that attempts to investigate humor in this age group should aim to include all four styles of humor. The current research also demonstrated the value of paired interviews when carrying out this sort of research with children. PMID:27547258

    2012-01-01

    Background In contrast with an early implicit “facilitative hypothesis” of humor, a revised specificity hypothesis predicts that the benefits of humor depend on the specific style of humor used. Information on predictors of these humor styles in turn enhances the ability to predict the effect on well-being. Methods We examined the relationships between interpersonal competence, self-esteem, and different styles of humor, while also examining the contributions of age and gender. Participants (n = 201) aged 18–63 years completed the Rosenberg Self-Esteem Inventory, the Interpersonal Competence Questionnaire, and the Humor Styles Questionnaire, and gave demographic information. Results High self-esteem was associated with higher use of affiliative, aggressive, and self-enhancing humor styles, but lower use of self-defeating humor. High interpersonal competence predicted greater use of affiliative humor, whereas low interpersonal competence predicted greater use of aggressive humor. Further analyses showed that initiation competence predicted affiliative humor (positively) but both initiation competence (positively) and conflict management competence (negatively) predicted aggressive humor. Conclusion The findings that both self-esteem and initiation competence contribute to use of aggressive humor add to knowledge of who is likely to use this potentially harmful humor style. We conclude that a readiness to initiate humorous interactions is not on its own a general and positive attribute contributing to “good” humor. PMID:23180973

    Full Text Available Gender-related humors have their own way of being funny; and this research aims to find out how and why they are funny. For this purpose, both researchers have collected 50 gender cyber humors and analyzed them, first, to decode how their logical mechanism relates to specific linguistic features, and secondly, to uncover how gender stereotyping contributes to the comical effects. The twisting of logic and linguistic ambiguity is analyzed formally using Attardos (2001 General Theory of Verbal Humor (GTVH and supported by gender studies. The findings reveal that the logical mechanism consists of elements of incongruities, and gender stereotyping presents negative stereotypical images. The analysis further shows that some gender stereotypical images ridicule traditional roles of man and woman while others make fun of non-traditional representations. This shift from women only to both men and women as targets of gender humors has been an impact of effective feminist movements.

    This project explores the regional phospholipid distribution in porcine vitreous humor, retina, and lens. Matrix-assisted laser desorption mass spectrometry has been used previously to image lipids, proteins, and other metabolites in retinas and lenses. However, the regional composition of phospholipids in vitreous humors is not known. To address this issue, we have applied this mass spectral method to explore the regional phospholipid distribution in porcine vitreous humor both ex-situ and in-vitro. To establish the possible source(s) of phospholipids in the vitreous humor, compositional studies of the lens and retina were also pursued. Due to the overall low levels of phospholipids in vitreous humor, it was necessary to optimize the experimental approaches for ex-situ and in-vitro studies. The sensitivity observed in the spectra of methanol extracts from the lens and retina was higher than that for methanol:chloroform extracts, but the compositional trends were the same. A fourfold improvement in sensitivity was observed in the analysis of vitreous humor extracts obtained with the Bligh and Dyer protocol relative to the other two extraction methods. For ex-situ studies, the 'stamp method' with para-nitroaniline as the matrix was chosen. Throughout the vitreous humor, phosphatidylcholines were the most abundant phospholipids. In-vitro results showed higher relative levels of phospholipids compared to the 'stamp' method. However, more details in the regional phospholipid distribution were provided by the ex-situ approach. Both in-vitro and ex-situ results indicated higher levels of phospholipids in the posterior vitreous region, followed by the anterior and central regions. The posterior region contained more unsaturated species whereas more saturated phospholipids were detected in the anterior region. The observed trends suggest that the phospholipids detected in the posterior vitreous humor migrate from the retina and associated vasculature while those present in

    2011-01-01

    Background It seems that the core neural regions and cognitive processes implicated in obsessive-compulsive disorder (OCD) pathophysiology may overlap with those involved in humor appreciation. However, to date, there have been no studies that have explored humor appreciation in OCD. The purpose of the present work was to investigate humor appreciation in a group of patients with OCD. Methods We examined 25 patients with OCD and 25 healthy controls, matched by age, education, and gender. We administered Penn's Humor Appreciation Test (PHAT), a computerized test comprising captionless cartoons by Mordillo. Each set of stimuli consisted of two almost identical drawings, one of which was funny due to the alteration of a detail in the cartoon, whereas the other was not funny. Severity of psychopathology was evaluated with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). Results No significant effect for group, gender or group × gender interaction was found on the PHAT scores. In OCD patients, humor appreciation was not significantly associated with age of onset, duration of illness, and obsessions, but correlated significantly with compulsions. Conclusions Humor appreciation, based on captionless cartoons in OCD, does not seem to be deficient compared to healthy subjects but may be related to illness characteristics. PMID:22103926

    Human emotions, such as anxiety, depression, fear, joy, and laughter, profoundly affect psychological and physiological processes. These emotions form a set of basic, evolved functions that are shared by all humans. Laughter is part of a universal language of basic emotions that all humans recognize. Health care providers and educators may utilize the power of laughter to improve health and enhance teaching and learning. This is an important consideration because teaching is not just about content: it is also about forming relationships and strengthening human connections. In this context, when used effectively, humor is documented to build relationships and enhance performance. Specifically, humor improves student performance by attracting and sustaining attention, reducing anxiety, enhancing participation, and increasing motivation. Moreover, humor stimulates multiple physiological systems that decrease levels of stress hormones, such as cortisol and epinephrine, and increase the activation of the mesolimbic dopaminergic reward system. To achieve these benefits, it is important to use humor that is relevant to the course content and not disparaging toward others. Self-effacing humor illustrates to students that the teacher is comfortable making mistakes and sharing these experiences with the classroom. In this brief review, we discuss the history and relationship between humor, laughing, learning, and health with an emphasis on the powerful, universal language of laughter.

    2016-08-01

    This study assessed the concurrent and prospective associations between psychosocial adjustment and four humor styles, two of which are adaptive (affiliative, self-enhancing) and two maladaptive (aggressive, self-defeating). Participants were 1,234 adolescents (52% female) aged 11-13 years, drawn from six secondary schools in England. Self-reports of psychosocial adjustment (loneliness, depressive symptomatology, and self-esteem) and humor styles were collected at two time points (fall and summer). In cross-lagged panel analyses, self-defeating humor was associated with an increase in both depressive symptoms and loneliness, and with a decrease in self-esteem. In addition, depressive symptoms predicted an increase in the use of self-defeating humor over time, indicating that these may represent a problematic spiral of thoughts and behaviors. Self-esteem was associated with an increase in the use of affiliative humor over the school year but not vice-versa. These results inform our understanding of the ways in which humor is associated with psychosocial adjustment in adolescence.

    This research summarizes the knowledge generated in social psychology and positive psychology about the relationship between humor styles, personality and wellbeing. Specifically, a meta-analysis was performed with the results of 15 studies on humor styles measured by the Humor Styles Questionnaire (Martin, Puhlik-Doris, Larsen, Gray & Weir, 2003) in correlation with the personality traits measured by the Big Five Personality model (measured with different scales). Following the steps presented by Rosenthal (1991) for meta-analysis in the case of correlational research, we calculated the total mean r as an indicator of effect size. Results show that affiliative humor has a strong and homogeneous relation to neuroticism and extraversion. The homogeneity and heterogeneity found between variables and possible explanations are discussed in the conclusion. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    The authors propose an effective technique to isolate whole, intact vitreous core and cortex from post mortem enucleated porcine eyes. While previous studies have shown the results of such dissections, the detailed steps have not been described, precluding researchers outside the field from replicating their methods. Other studies harvest vitreous either through aspiration, which does not maintain the vitreous structure anatomy, or through partial dissection, which only isolates the vitreous core. The proposed method isolates the whole vitreous body, with the vitreous core and cortex intact, while maintaining vitreous anatomy and structural integrity. In this method, a full thickness scleral flap in an enucleated porcine eye is first created and through this, the choroid tissue can be separated from the sclera. The scleral flap is then expanded and the choroid is completely separated from the sclera. Finally the choroid-retina tissue is peeled off the vitreous to leave an isolated intact vitreous body. The proposed vitreous dissection technique can be used to study physical properties of the vitreous humor. In particular, this method has significance for experimental studies involving drug delivery, vitreo-retinal oxygen transport, and intraocular convection.

  15. Eosinophils: important players in humoral immunity.

    Science.gov (United States)

    Berek, C

    2016-01-01

    Eosinophils perform numerous tasks. They are involved in inflammatory reactions associated with innate immune defence against parasitic infections and are also involved in pathological processes in response to allergens. Recently, however, it has become clear that eosinophils also play crucial non-inflammatory roles in the generation and maintenance of adaptive immune responses. Eosinophils, being a major source of the plasma cell survival factor APRIL (activation and proliferation-induced ligand), are essential not only for the long-term survival of plasma cells in the bone marrow, but also for the maintenance of these cells in the lamina propria which underlies the gut epithelium. At steady state under non-inflammatory conditions eosinophils are resident cells of the gastrointestinal tract, although only few are present in the major organized lymphoid tissue of the gut - the Peyer's patches (PP). Surprisingly, however, lack of eosinophils abolishes efficient class-switching of B cells to immunoglobulin (Ig)A in the germinal centres of PP. Thus, eosinophils are required to generate and to maintain mucosal IgA plasma cells, and as a consequence their absence leads to a marked reduction of IgA both in serum and in the gut-associated lymphoid tissues (GALT). Eosinophils thus have an essential part in long-term humoral immune protection, as they are crucial for the longevity of antibody-producing plasma cells in the bone marrow and, in addition, for gut immune homeostasis. © 2015 British Society for Immunology.

    It has been established by MRI visualization experiments that the convection of nanoparticles and large molecules with high rate of water flow in the vitreous humor will experience resistance, depending on the respective permeabilities of the injected solute. A set of experiments conducted with Gd-DTPA (Magnevist, Bayer AG, Leverkusen, Germany) and 30 nm gadolinium-based particles (Gado CELLTrackTM, Biopal, Worcester, MA) as MRI contrast agents showed that the degree of convective transport in this Darcy-type porous medium varies between the two solutes. These experiments consisted of injecting a mixture of the two (a 30 μl solution of 2% Magnevist and 1% nanoparticles) at the middle of the vitreous of an ex vivo whole bovine eye and subjecting the vitreous to water flow rate of 100 μl/min. The water (0.9% saline solution) was injected at the top of the eye, and was allowed to drain through small slits cut at the bottom of the eyeball. After 50 minutes of pumping, MRI images showed that the water flow carried the Gd-DTPA farther than the nanoparticles, even though the two solutes, being mixed, were subjected to the same convective flow conditions. We find that the convected solute lags the water flow, depending on the solute permeability. The usual convection term needs to be adjusted to allow for the filtration effect on the larger particles in the form (1- σ) u . ∇ c with important implications for the modeling of such systems.

    Full Text Available Projetos Locais de Conservação e Desenvolvimento Integrados são uma estratégia para a conservação da biodiversidade largamente adotada nas últimas décadas por ONGs e agências de cooperação internacional. Esses projetos caracterizam-se por objetivos de conservação associados ao desenvolvimento socioeconômico de populações locais, dentro ou no entorno de áreas protegidas. Neste trabalho analiso 25 avaliações de projetos, em 18 países, identificando o espectro de respostas deflagradas. Foram identificadas 34 diferentes respostas, o que evidencia o potencial desses projetos em produzir mudanças nos sistemas locais. No entanto, em metade dos casos (14 de 25, as ações desenvolvidas pelos projetos não produziram respostas identificáveis e, dentre os casos onde se observaram respostas, muitas delas podem ter efeitos contraprodutivos. Os resultados apontam para os riscos associados a essas intervenções e para a necessidade de abordar seu desenho, avaliação e investigação científica a partir de um ponto de vista sistêmico.

    2016-08-01

    The Humor Styles Questionnaire (HSQ; Martin et al., 2003) is one of the most frequently used questionnaires in humor research and has been adapted to several languages. The HSQ measures four humor styles (affiliative, self-enhancing, aggressive, and self-defeating), which should be adaptive or potentially maladaptive to psychosocial well-being. The present study analyzes the internal consistency, factorial validity, and factorial invariance of the HSQ on the basis of several German-speaking samples combined (total N = 1,101). Separate analyses were conducted for gender (male/female), age groups (16-24, 25-35, >36 years old), and countries (Germany/Switzerland). Internal consistencies were good for the overall sample and the demographic subgroups (.80-.89), with lower values obtained for the aggressive scale (.66-.73). Principal components and confirmatory factor analyses mostly supported the four-factor structure of the HSQ. Weak factorial invariance was found across gender and age groups, while strong factorial invariance was supported across countries. Two subsamples also provided self-ratings on ten styles of humorous conduct (n = 344) and of eight comic styles (n = 285). The four HSQ scales showed small to large correlations to the styles of humorous conduct (-.54 to .65) and small to medium correlations to the comic styles (-.27 to .42). The HSQ shared on average 27.5-35.0% of the variance with the styles of humorous conduct and 13.0-15.0% of the variance with the comic styles. Thus-despite similar labels-these styles of humorous conduct and comic styles differed from the HSQ humor styles.

    Humor is a potential communication strategy to accomplish various and potentially conflicting consultation goals. We investigated humor use and its reception in diabetes consultations by analyzing how and why humor emerges and its impact on the interaction. We did this by using an interactional sociolinguistics approach. We recorded 50 consultations in an Irish diabetes setting. Analysis of the humor events drew on framework analysis and on concepts from Conversation Analysis and pragmatics. The study also comprised interviews using tape-assisted recall. We identified 10 humor functions and two umbrella functions. A key finding is that most humor is relationship-protecting humor initiated by patients, that is, they voice serious messages and deal with emotional issues through humor. Our findings imply that patients' and providers' awareness of indirect communication strategies needs to be increased. We also recommend that researchers employ varied methods to adequately capture the interactive nature of humor.

    The prevalence of antibodies to pancreatic islets in monogenic diabetes remains unknown and the incidence estimation is difficult as the occurrence of autoantibodies in patient is one of the well-known exclusion criteria for further genetic diagnostics. They has been found not only among patients with type 1 diabetes, but also in other types of diabetes: Type 2 diabetes, Latent Autoimmune Diabetes in Adults (LADA) (16) and monogenic diabetes (MD). Immunological characteristic of GCK MODY patients. The study group included families of 27 adolescent patients with GCK MODY (39 parents and 19 siblings) monitored in the Department of Pediatrics, Endocrinology and Diabetes and in the Diabetes Clinic of John Paul II Upper Silesian Child Health Centre in Katowice in the years 2007-2012. All patients and family members with GCK MODY underwent a blood sample drawing for immunological (classic humoral response markers: ICA, GAD, IA-2, IAA) and biochemical diagnostics. Pediatric, diabetes and family medical history was collected from the subjects and parents. Immunological diagnostics was performed in all patients except 1 (96.3%). Immunological diagnostics included 17 (89.5%) parents and 7 (87.5%) siblings with diagnosed GCK MODY. 8 (30.8%) adolescent patients with GCK MODY, 3 subjects (17.64%) among parents (with GCK MODY), as well as 2 subjects (28.57%) among siblings (with GCK MODY) showed a positive antibodies screen. The results of our study in children with GCK MODY and their family members suggest that the occurrence of classic antibodies directed against pancreatic islets antigens is fairly common in patients with GCK MODY. Despite various observations and many legitimate discussions, it is difficult to clarify the pathogenesis of the occurrence of autoantibodies in monogenic diabetes. © Polish Society for Pediatric Endocrinology and Diabetology.

    We intravenously administered flomoxef sodium (FMOX) 120 minutes before cataract surgery, topically administered levofloxacin (LVFX) into the eyes four times at 30-minute intervals before surgery, and measured the aqueous humor concentrations of these agents to investigate their penetration into the aqueous humor and their efficacy in the prevention of postoperative endophthalmitis. Sixty-eight patients who underwent cataract surgery at the Department of Ophthalmology, Yokohama City University School of Medicine, or its affiliate, Kanazawa Hospital, Yokohama, were enrolled in this study. They received one or both of the following: 1.0 g FMOX via a 20-minute intravenous drip and LVFX ophthalmic solution applied four times at 30-minute intervals, both beginning two hours before the operation. Aqueous humor was aspirated from the anterior chamber and assayed for FMOX and LVFX concentrations using high-performance liquid chromatography (HPLC). The mean intraoperative FMOX and LVFX concentrations in the patients' aqueous humor were 1.21 +/- 0.63 microg/ml and 0.69 +/- 0.47 microg/ml, respectively. These concentrations sufficiently exceeded the MIC90 values against Staphylococcus epidermidis, S. aureus, and Propionibacterium acnes. The FMOX and LVFX concentrations in the aqueous humor sampling were adequate to kill bacteria in vitro. These drugs may have efficacy in the prevention of postoperative endophthalmitis in patients undergoing cataract surgery.

    We intravenously administered flomoxef sodium (FMOX) 0.5-3.5 hours before cataract surgery and measured the concentration of the agent in the aqueous humor to investigate its penetration into the aqueous humor and its efficacy in the prevention of postoperative endophthalmitis. 56 patients who underwent cataract surgery were enrolled in this study. They received 1 g FMOX via a 20-minute intravenous drip beginning 0.5-3.5 hours before the operation. Aqueous humor was aspirated from the anterior chamber and assayed for FMOX concentration using high-performance liquid chromatography. The mean intraoperative FMOX concentrations in the patients' aqueous humor were 0.79 +/- 0.24 microg/ml (administered 3.5 hours before surgery)--1.47 0.79 microg/ml (administered 1.5 hours before surgery). These concentrations administered 0.5-3.0 hours before surgery sufficiently exceeded the minimum inhibitory concentration (MIC) 90 values against Staphylococcus epidermidis, Staphylococcus aureus and Propionibacterium acnes, but did not achieve the MIC90 values against Enterococcus faecalis and Pseudomonas aeruginosa. The FMOX concentrations in the aqueous humor sampling were adequate to kill bacteria in vitro. This drug may be efficacious in the prevention of postoperative endophthalmitis in patients undergoing cataract surgery.

    The association between relational aggression and popularity during early adolescence is well established. Yet, little is known about why, exactly, relationally aggressive young adolescents are able to achieve and maintain high popular status among peers. The present study investigated the mediating role of humor in the association between relational aggression and popularity during early adolescence. Also considered was whether the association between relational aggression and humor varies according to adolescents’ gender and their friends’ levels of relational aggression. Participants were 265 sixth-grade students (48% female; 41% racial/ethnic minority; Mage = 12.04 years) who completed peer nomination and friendship measures in their classrooms at two time points (Wave 1: February; Wave 2: May). The results indicated that Wave 1 relational aggression was related to Wave 1 and 2 popularity indirectly through Wave 1 humor, after accounting for the effects of Wave 1 physical aggression, ethnicity, and gender. Additional analyses showed that relational aggression and humor were related significantly only for boys and for young adolescents with highly relationally aggressive friends. The results support the need for further research on humor and aggression during early adolescence and other mechanisms by which relationally aggressive youth achieve high popular status.

    Conversation analysis is employed to examine transcribed excerpts drawn from a subsample of 75 naturally occurring and video recorded interviews between cancer patients and 30 doctors. Close examination is provided of how cancer patients initiate, and doctors respond, to laughter and humor during oncology interviews. Interactions demonstrate that communication about the disease "cancer" shares qualities similar to other medical areas (e.g., primary care): the tendency for patients to initiate laughter or humor to address troubling and challenging circumstances; and that during moments when patients address personal matters, doctors are not invited and do not reciprocate with shared laughter and humor. Prominent in talk about cancer are various precarious circumstances, awkward and delicate moments mirroring the lived experiences of cancer patients (e.g., when patients attempt to minimize fears, justify that they are well when threatened with sickness, claim normality in the midst of chronic conditions, and take stances that weight loss and gain are not problematic). These examples provide a compelling case that routine cancer care involves many poignant situations managed through laughter and humor. Implications are raised for how quality care might be improved through grounded understandings of laughter, humor, and cancer.

    Full Text Available Bernadette McCosker, Carmen C MoranSchool of Psychology, Charles Sturt University, Wagga Wagga, NSW, AustraliaBackground: In contrast with an early implicit “facilitative hypothesis” of humor, a revised specificity hypothesis predicts that the benefits of humor depend on the specific style of humor used. Information on predictors of these humor styles in turn enhances the ability to predict the effect on well-being.Methods: We examined the relationships between interpersonal competence, self-esteem, and different styles of humor, while also examining the contributions of age and gender. Participants (n = 201 aged 18–63 years completed the Rosenberg Self-Esteem Inventory, the Interpersonal Competence Questionnaire, and the Humor Styles Questionnaire, and gave demographic information.Results: High self-esteem was associated with higher use of affiliative, aggressive, and self-enhancing humor styles, but lower use of self-defeating humor. High interpersonal competence predicted greater use of affiliative humor, whereas low interpersonal competence predicted greater use of aggressive humor. Further analyses showed that initiation competence predicted affiliative humor (positively but both initiation competence (positively and conflict management competence (negatively predicted aggressive humor.Conclusion: The findings that both self-esteem and initiation competence contribute to use of aggressive humor add to knowledge of who is likely to use this potentially harmful humor style. We conclude that a readiness to initiate humorous interactions is not on its own a general and positive attribute contributing to “good” humor.Keywords: self-esteem, interpersonal competence, humor styles, differential effects

    Full Text Available Formal language education is often predicated on a series of modernist fictions that greatly simplify the nature of language and the process of communication. Acts of linguistic creativity involving humor and language play are frequently either ignored or considered deviant. In this paper, we contribute to ongoing efforts to re-conceptualize language education in ways that make use of more robust (and less modernist theories of language and communication. We revisit calls for more pedagogical focus on humor and language play and illustrate how more attention to these types of language might help us to move away from some of the classroom fictions that currently constrain teachers and learners alike. Specifically, we present recent conceptions of language and of communication, and discuss how, in light of these, humor and language play can be used to increase learners’ metalinguistic awareness and expand their communicative/interpretive repertoires.

    2001-04-01

    Effectiveness of systematic desensitization for fear reduction, using humorous hierarchy scenes without relaxation, was tested. Participants were 40 students highly fearful of spiders. Using a 24-item behavioral approach test with an American tarantula, participants were matched on fear level and randomly assigned to 1 of 3 treatment groups: (a) systematic desensitization, (b) humor desensitization, and (c) untreated controls. Each participant was seen for 6 sessions, including pretest and posttest. Analyses of covariance of posttest scores revealed that the 2 treatment groups showed greater reduction in fear than the controls on 3 measures but did not differ from each other. Therefore, humor in systematic desensitization reduced fear as effectively as more traditional desensitization. This finding may have therapeutic applications; however, it may also be applicable in advertising to desensitize fear of a dangerous product, such as cigarettes.

  9. Does Sense of the Humor Make Sense in the Classroom?

    2011-11-01

    Full Text Available This paper studies the importance of humor as a teaching strategy in the classroom, considering the usual lack of motivation and boredom. To analyze whether the “happy teaching and happy learning” may increase effectiveness in the teaching-learning process, the author will discuss how, despite the many benefits it may bring, humor is not used in the classroom due to prejudices and fears. The idea is not for teachers to play the role of a comedian or a clown, but to intervene and get closer to the group with a teaching, didactic purpose through humor. Plato (1992 thought about this; he used to say that sometimes a joke may help, where seriousness put up resistance.

  10. The Use of Humor in Serious Mental Illness: A Review

    2011-01-01

    Full Text Available There is now a relatively good understanding of the broad range of direct and indirect effects of humor and laughter on perceptions, attitudes, judgments and emotions, which can potentially benefit the physical and psychological state. This article presents a review and discussion of the use of humor and laughter in treating people with serious mental illness, distinguishing between clinical papers on individual and group psychotherapy, and empirical research reports describing humor and laughter interventions. In spite of the exponential growth of the field over the last 30 years, I conclude that empirical studies are still lacking, the studies that do exist have major methodological shortcomings, and the field is in dire need of further investigation.

    Full Text Available This paper investigates the concepts of humor and violence and their complex relationships contextualised in the advertising domain. Thus, the main theories of humor and the most important elements from media violence paradigms are critically pointed out. The effects of comedic violence in advertising may be positive (great involvement with the ad message, retention of brand information, higher pass-along probability, and also negative (offending the audience, desensitization, damaging the reputation and the brand equity. A lot of factors change the perception of comedic violent ads (gender, social norm beliefs etc., so that a multidimensional analysis of consumer perceptions is needed if we want to draw a more accurate picture of this phenomenon. The analysis of the specific ad that I developed in the second part of this paper showed clearly the interplay between perceived humor and perceived violence and also the relevance of the cultural background in its interpretation.

    Humor is, from a psychological point of view, a complex process involving cognitive, affective, interspersonal and social elements in a interpersonal context. Its cognitive core is based on the perception of incongruity between two related inconsistent or contradictory mental representations. The total or partial resolution of incongruity in a playful frame is associated with a specific positive emotion, which characteristics and intensity are determined by the structure of the humoristic stimulus more than its content, and the personal and social contexts. Main theories of humor are reviewed as well as its development, its cognitive and affective correlates, and the influence of genre, age and personality.

    As a mature science, geophysics often employs abstract mathematical ideas in the development of methods to query the physical system. Since abstract mathematics is not usually part of the traditional meteorological education, it is sometimes necessary to communicate these ideas in a manner that not only explains but also demystifies them. Humor is an ideal tool for allowing an audience to develop a degree of comfort with unfamiliar concepts. I will give several examples where abstract ideas are made concrete in the context of stochastic climate modeling by use of humorous presentations.

    2014-01-01

    This study tested the effect of humor in one particular type of print advertisement: the preventive health ads for three topics (alcohol, tobacco, obesity). Previous research using commercial ads demonstrated that individuals' attention is spontaneously attracted by humor, leading to a memory advantage for humorous information over nonhumorous information. Two experiments investigated whether the positive effect of humor can occur with preventive health ads. In Experiment 1, participants observed humorous and nonhumorous health ads while their viewing times were recorded. In Experiment 2, to compare humorous and nonhumorous ads, the memory of health messages was assessed through a recognition task and a convincing score was collected. The results confirmed that, compared to nonhumorous health ads, those using humor received prolonged attention, were judged more convincing, and their messages were better recognized. Overall, these findings suggest that humor can be of use in preventive health communication.

    Throughout the literature, humor has demonstrated positive effects on memory and learning, as well as physiological and psychological well being. Research has described improvements in communication and trust through the use of humor in the nurse-patient relationship. The utilization of humor with certain populations, including those with anxiety disorders, cancer patients and mood disorders has also been widely described in the literature but little research has been conducted with humor use in patients' recovery from substance use disorders. This population might benefit from the thoughtful applications of humor to promote laughter and mirth as well as learning recovery principles. A review of the humor theories, theoretical processes and humor styles are discussed for their use in individuals with substance use disorders, in particularly for early recovery engagement in 12 step programs and other recover support social networks. The application of humor in efforts to support recovery with substance use disorder patients is worth investigating further.

    Full Text Available Este artigo aborda a globalização como um complexo processo de institucionalização e examina o potencial da teoria institucional na elucidação das características do fenômeno, em especial, na forma específica como se manifesta nas regiões periféricas. Distingue-se uma globalização hegemônica, que se realiza como difusão institucional a partir dos países cêntricos, de uma globalização contra-hegemônica, constituída de respostas estratégicas de baixo para cima. Com uma síntese entre o "velho" e o "novo" institucionalismos na vertente organizacional, a teoria institucional parece habilitar-se a contextualizar o processo em sua dualidade local/global. Argumenta-se, no entanto, que por excessivo apego à idéia da tendência normal ao equilíbrio, essa teoria encontra dificuldades para lidar com os aspectos dinâmicos do fenômeno, particularmente, os que envolvem conflito e mudança de valores. Embora as alternativas de resposta consideradas por Oliver (1991 incluam variadas formas de resistência contra a conformidade às pressões exógenas, este estudo defende, a exemplo de Zimmerman e Zeitz (2002, uma tipologia ampliada de respostas estratégicas. Com a inclusão da resposta da criação, essa tipologia parece espelhar melhor os contrastantes processos da globalização, inclusive, os que implicam mudanças fundamentais no próprio ambiente.

    Full Text Available The article discusses how humor could enrich social work practice and guideline social workers. Social work field is not that traditionally relates with humor. While social work scholars argue that social work field is full of contradictions and humor is relevant tool to express those contradictions and paradoxes. In micro level practice Gitterman (2003 suggests humor could be a creative tool that “must be used differently based on client background, level of functioning, and specific situation”. Article presents results of qualitative study. The analysis of social workers’ professional experiences is based on social constructionism perspective with the aim to explain how humor is used in everyday practice and how use of purposive humor could be helpful in social work intervention. Episodic interviews with six social workers working in intercultural social work field were conducted. Transcripts of interviews were analyzed through conceptualization, developing story and maximizing aims of the study. Anonymity and confidentiality was considered. The results of analysis demonstrate that humor is unique experience in the sociocultural context. Discursive categories explain the purpose of humor for practice, circumstances and conditions for using that determine how the use of humor could contribute to the success of a social worker-client interaction. Using humor is considered as professional competence, which suggests that “having a good sense of humor” and appropriate use of humor with ability to demonstrate empathy and honesty in social worker-client interaction is an important part of social worker competence. Humor as a professional competence contained understanding of the humorous taboo. During analysis were explored how using humor and cultural stories of clients create mezzo level strategies for professional social work practice. Keywords: humor in social work practice, social work process, humor taboo.

    Full Text Available OBJETIVO: Analisar instrumento de medição da adesão ao tratamento da hipertensão por meio da "Teoria da Resposta ao Item". MÉTODOS: Estudo analítico com 406 hipertensos com complicações associadas, atendidos na atenção básica em Fortaleza, CE, 2011, pela "Teoria da Resposta ao Item". As etapas de execução foram: teste de dimensionalidade, calibração dos itens; tratamento dos dados e construção da escala, analisadas com base no modelo de resposta gradual. Estudo da dimensionalidade do instrumento foi feito pela análise da matriz de correlação policórica e análise fatorial de informação completa. Utilizou-se o software Multilog para calibração dos itens e estimação dos escores. RESULTADOS: Os itens referentes ao tratamento medicamentoso foram os mais diretamente relacionados à adesão, enquanto aqueles referentes ao tratamento não medicamentoso precisam ser reformulados, pois possuíram menor quantidade de informação psicométrica e baixa discriminação. A independência dos itens, o reduzido número de níveis da escala e as baixas variâncias explicadas no ajuste dos modelos mostraram as principais fragilidades do instrumento analisado. A "Teoria da Resposta ao Item" mostrou-se relevante para análise, pois avaliou o respondente quanto à adesão ao tratamento da hipertensão, ao nível de dificuldade dos itens e à sua capacidade de discriminação entre indivíduos com diferentes níveis de adesão, o que gerou maior quantidade de informação. CONCLUSÕES: O instrumento analisado é limitado para medir a adesão ao tratamento da hipertensão, mediante análise pela "Teoria da Resposta ao Item", e necessita de ajustes. A adequada formulação dos itens é importante para medir precisamente o traço latente desejado.

With this Kožičić made Rijeka the cultural and spiritual seat of the Croatian Glagolitic movement and early European printing. This fact calls for a more detailed evaluation of Kožičić’s work in the present time and indicates a realistic possibility for the use of his work, an important part of Rijeka’s cultural heritage, with the aim of making the present and future of Rijeka and Croatia brighter. In the paper we start from the concepts of identity, brand, application of the process of branding, but also maintenance, that is, creation of identity and brand of town. Also some strategies that, with a good knowledge of Kožičić’s persona, work and time, and specific qualities of Rijeka, could be used and applied to the domains of science, culture and tourism foremostly in the town of Rijeka, are presented. Thus we speak about and propose a realisation of a project that is primarily cultural and scientific in its nature (Kozičić’s museum – a museum of Rijeka printing house; an Institute of Early Croatian Printing, etc., but also of economic and tourist projects (Kozičić’s printing house; “vetea et nova”, crafting of special kinds of paper, crafting of Renaissance and Baroque pottery with the symbols of Rijeka, Glagolitic script, etc., that is, crafting of appropriate souvenirs, organising a Renaissance bodega: shops and catering facilities.

  1. Humorous Names in the Light of Incongruity Theory

    Directory of Open Access Journals (Sweden)

    Mariusz Rutkowski

    2016-07-01

    Full Text Available The article addresses the humorous function of proper names in the light of incongruity theory. It aims at proving that, although names are often defined as pragmatically “transparent,” they may possess some humorous value due to semantic and pragmatic shifts resulting from the disturbance of ordinary patterns of proper names identification and interpretation. After a brief introduction, the author discusses different variants of incongruity theory as resented in the works by Victor Raskin and Thomas C. Veatch as well as their possible application to the study of humorous names. The second part of the paper provides an analysis of the humorous effects of proper names which includes anthroponyms, toponyms, trade names, football team names and names in literature. The first section of this part concentrates on names in which humour is unintentional and seems to be induced by the context, while the second section focuses on names which are intentionally humourous, i.e. supposed to amuse from the moment of their creation. The author argues that the incongruity theory can provide a useful framework for the study of the different mechanisms responsible of the semantic shifts which determine the variation of pragmatic values of proper names.

    Full Text Available We determined the antioxidant status of the aqueous humor after extracapsular lens extraction in 14 mongrel dogs weighing about 10 kg. The animals were examined by slit lamp biomicroscopy, applanation tonometry and indirect ophthalmoscopy. One eye was submitted to conventional extracapsular lens extraction and the other was used as control. Samples of aqueous humor were obtained by anterior chamber paracentesis before and at days 1, 2, 3, 7 and 15 after surgery. Total antioxidant status was determined as the capacity of aqueous humor to inhibit free radical generation by 2,2-azobis(2-amidopropane chlorine. Ascorbic acid concentration was measured by HPLC with UV detection. Protein content was determined with the biuret reagent. Statistical analysis was performed by ANOVA followed by the Tukey-Kramer test. Protein concentration increased from 0.61 to 22 mg/ml 24 h after surgery. These levels were maintained and returned to normal at day 7. Total antioxidant capacity was reduced from 50 to about 30 min until day 3 and at day 7 it was equal to control. Ascorbic acid levels were reduced from 252 to about 110 µM and then returned to control values at day 15. Considering the importance of ascorbic acid concentration in aqueous humor for the maintenance of the antioxidant status of the anterior segment of the eye, the decrease of antioxidant defenses suggests that the surgical procedures promote an oxidative stress condition in the eye.

    Directory of Open Access Journals (Sweden)

    Danilo Bianchini Höfling

    2008-12-01

    Full Text Available A tireoidite crônica auto-imune é, atualmente, a principal causa de hipotireoidismo e seu diagnóstico baseia-se nas manifestações clínico-laboratoriais. O marcador laboratorial mais importante é a presença de anticorpos antitireoglobulina e antiperoxidase, sendo este último o teste mais sensível. A biópsia aspirativa apresenta alta sensibilidade e especificidade, porém, é um método invasivo e, por isso, reservado para quando há presença de nódulo ou bócio de crescimento rápido. A cintilografia é desnecessária para o diagnóstico, já que apresenta baixa sensibilidade e especificidade. A ultra-sonografia, tanto ao modo B como ao dúplex-Doppler colorido, evoluiu de forma muito rápida e tornou-se um método simples, não-invasivo, reprodutível e com alta sensibilidade para o diagnóstico da tireoidite crônica auto-imune. Ao modo B, a ecogenicidade é um parâmetro de extrema importância, já que, além de apresentar alta correlação com o quadro citopatológico, também apresenta alta sensibilidade para o diagnóstico da tireoidite crônica auto-imune. Embora este parâmetro não seja específico da tireoidite crônica auto-imune, pois também pode estar presente na doença de Graves, na tireoidite pós-parto e na tireoidite subaguda, tais desordens podem ser facilmente diferenciadas tanto pelo quadro clínico-laboratorial quanto pelo dúplex-Doppler colorido. Assim, este artigo tem o objetivo de revisar a importância do estudo da ecogenicidade no diagnóstico da tireoidite crônica auto-imune.Chronic autoimmune thyroiditis is currently considered as the main cause for hypothyroidism and its diagnosis is based on clinical manifestations and laboratory tests results. The most significant laboratory marker for this disease is the presence of anti-thyroperoxidase and anti-thyroglobulin antibodies, the latter being the most sensitive one. Aspiration biopsy shows high sensitivity and specificity but, considering the

    Antibiotics such as fluoroquinolones (FQLs) are commonly used to treat ocular infections but are also known to cause dermal melanocyte toxicity. The release of dispersed pigments from the iris into the aqueous humor has been considered a possible ocular side effect of the systemic administration of FQLs such as Moxifloxacin, and this condition is known as bilateral acute iris transillumination (BAIT). Bilateral acute depigmentation of iris (BADI) is a similar condition, with iris pigment released into the aqueous, but it has not been reported as a side effect of FQL. Iris pigments are synthesized by the melanogenic enzyme tyrosinase (TYR) and can be detected but not quantified by using slit-lamp biomicroscopy. The correlation between dispersed pigments in the aqueous and the extent of melanocyte toxicity due to topical antibiotics in vivo is not well studied. Here, we aimed to study the effect of topical FQLs on iris tissue, the pigment release in the aqueous humor and the development of clinically evident iris atrophic changes. We evaluated this process by measuring the activity of TYR in the aqueous humor of 82 healthy eyes undergoing cataract surgery following topical application of FQLs such as Moxifloxacin (27 eyes, preservative-free) or Ciprofloxacin (29 eyes, with preservative) or the application of non-FQL Tobramycin (26 eyes, with preservative) as a control. In addition, the patients were questioned and examined for ocular side effects in pre- and post-operative periods. Our data showed a significantly higher mean TYR activity in the aqueous humor of Ciprofloxacin-treated eyes compared to Moxifloxacin- (preservative free, p iris melanocytes. However, the reduced TYR activity in the aqueous of Moxifloxacin-treated eyes was possibly due to the presence of a higher drug concentration, which inhibits TYR activity. Consistently, immunoblotting analysis of the aqueous humor from both Ciprofloxacin- and Moxifloxacin-treated eyes showed the presence of soluble

    Hereditary hyperferritinemia cataract syndrome (HHCS) is a rare autosomal dominant hereditary disease, characterized by hyperferritinemia but with absence of body iron excess and early onset of bilateral cataracts. Although 5- to 20-fold increased serum ferritin concentrations have been reported in HHCS patients, data of ferritin levels in aqueous humor have not been obtained. We therefore aimed to investigate the ferritin levels in aqueous humor and serum and further present histological and ultrastructural data of the lens. During cataract extraction and intraocular lens implantation, aqueous humor and lens aspirate of a 37-year-old HHCS patient were obtained from both eyes. Ferritin levels in serum and aqueous humor were quantitatively analyzed via immunoassays in the HHCS patient and healthy control subjects (n = 6). Lens aspirate in HHCS was analyzed histologically and at the ultrastructural level. Further, genetic mutation screening by polymerase chain reaction and DNA sequencing in blood was performed. Serum ferritin levels in the control group were 142.2 ± 38.7 μg/L, whereas in the HHCS patient, this parameter was excessively increased (1086 μg/L). Analysis of ferritin in aqueous humor revealed 6.4 ± 3.8 μg/L in normal control subjects and 146.3 μg/L (OD) and 160.4 μg/L (OS) in the HHCS patient. DNA analysis detected a C>A mutation on position +18, a T>G mutation on position +22, a T>C mutation on position +24, and a T>G polymorphism on position +26 in the iron-responsive element of the light-chain ferritin (L-ferritin) gene. In the HHCS patient, a 23-fold (OD) to 25-fold (OS) increased aqueous humor ferritin level was detected. Therefore, the formation of bilateral cataract in HHCS is most likely a result of elevated aqueous humor ferritin. In addition, a novel mutation in this rare disease in the iron-responsive element of L-ferritin gene is reported.

    2007-01-01

    Full Text Available Theories about black humor usually regard that it as a contemporary phenomenon and a culmination of the literary modernism and beginning of post-modernism. My intent in this paper is to refute the thesis that the black humor is a modern invention. I am going to prove its existence still in Greek antiquity, quoting and analyzing humorous epitaphs and black humor epigrams. Putting in relation black humor with the joy and humor in religious (fertility and funeral rituals, I am also going to set a question about the attitude to death and life inherent for this kind of humor, arguing that its origin should be searched in the folk tradition.

  16. Rumination, Suicidal Ideation, and the Mediating Effect of Self-Defeating Humor

    Directory of Open Access Journals (Sweden)

    Raymond P. Tucker

    2014-08-01

    Full Text Available Research has demonstrated that a self-defeating humor style is related to indicators of psychopathology and interpersonal dysfunction, including depression, anxiety, loneliness, thwarted belongingness, and perceived burdensomeness. The current study continued this investigation by examining how self-defeating humor is related to suicidal ideation and a ruminative response style. Analyses indicated that a self-defeating humor style was positively associated to rumination, brooding, reflection, and suicidal ideation. Results of bootstrapping analyses indicated that self-defeating humor mediated the relationship between rumination and suicidal ideation. This same effect was seen for both brooding and reflection individually. Results indicate that self-defeating humor may serve as an interpersonal means of ruminating as this humor style involves consistent focus on perceived flaws and weaknesses. The assessment of this humor style may provide additional information about the maintenance of suicidal thinking.

    2016-04-01

    In this study we aimed to examine the contents of humor in the Japanese workplace and to understand the effects of humor on mental/physical health and self-evaluation of job performance. Japanese workers (N = 436) responded to questionnaires addressing workplace humor, feelings about workplace, workplace communication, mental/physical health, and perceived job performance. An exploratory factor analysis indicated that there are five types of workplace humor: norm-violating humor, experience-sharing humor workplace-enjoying humor, people-recalling humor, and outside-mocking humor. A covariance structural analysis showed that norm-violating humor and workplace-enjoying humor decreased mental and physical health by promoting both negative feelings in the workplace and self-disclosure about the negative side of work. Results also revealed that experience-sharing humor, people-recalling humor, and outside-mocking humor had a positive effect on the self-evaluation of job performance as well as mental and physical health, by promoting both positive feelings and mutual communication in the workplace. Results suggest that humor in the workplace has various influences on workers depending on the type of workplace humor.

    2014-08-01

    Full Text Available In this interview, Dr. Arnie Cann discusses his research and views on the ubiquitous role of humor in psychological health and well-being. The interview begins with Professor Cann recounting how he originally became interested in studying humor. He then reflects on the main findings associated with the wide variety of humor-related studies he has conducted over the years. In doing so, Dr. Cann provides suggestions and ideas for further research investigating the role of humor in health and well-being. Specific topic areas discussed include the use of humor in the workplace and other social domains, personality approaches to humor, humor and interpersonal processes, humor and psychopathology, and humor’s role in dealing with stress and well-being. One of the prominent themes in this interview is the clear recognition of sense of humor as a multi-dimensional construct that includes various components that may either be beneficial or detrimental to well-being. A further important theme is the major distinction between humor as an inherent personality construct versus humor that results from exposure to stimuli (e.g., a comedy film. Comments are also provided by Dr. Cann on how the positive affect stemming from humor may be of particular benefit to the individual. Also discussed is the recent move to more fully integrate contemporary humor research with positive psychology approaches. The interview concludes with Dr. Cann providing several recommendations regarding future theorizing and research on the role of humor in psychological well-being.

    Full Text Available How strongly does humor (i.e., the construct-relevant content in the Humor Styles Questionnaire (HSQ; Martin et al., 2003 determine the responses to this measure (i.e., construct validity? Also, how much does humor influence the relationships of the four HSQ scales, namely affiliative, self-enhancing, aggressive, and self-defeating, with personality traits and subjective well-being (i.e., criterion validity? The present paper answers these two questions by experimentally manipulating the 32 items of the HSQ to only (or mostly contain humor (i.e., construct-relevant content or to substitute the humor content with non-humorous alternatives (i.e., only assessing construct-irrelevant context. Study 1 (N = 187 showed that the HSQ affiliative scale was mainly determined by humor, self-enhancing and aggressive were determined by both humor and non-humorous context, and self-defeating was primarily determined by the context. This suggests that humor is not the primary source of the variance in three of the HQS scales, thereby limiting their construct validity. Study 2 (N = 261 showed that the relationships of the HSQ scales to the Big Five personality traits and subjective well-being (positive affect, negative affect, and life satisfaction were consistently reduced (personality or vanished (subjective well-being when the non-humorous contexts in the HSQ items were controlled for. For the HSQ self-defeating scale, the pattern of relationships to personality was also altered, supporting an positive rather than a negative view of the humor in this humor style.

    Humans naturally have a sense of humor. Experiencing humor not only encourages social interactions, but also produces positive physiological effects on the human body, such as lowering blood pressure. Recent neuro-imaging studies have shown evidence for distinct mental state changes at work in people experiencing humor. However, the temporal characteristics of these changes remain elusive. In this paper, we objectively measured humor-related mental states from single-trial functional magnetic resonance imaging (fMRI) data obtained while subjects viewed comedy TV programs. Measured fMRI data were labeled on the basis of the lag before or after the viewer’s perception of humor (humor onset) determined by the viewer-reported humor experiences during the fMRI scans. We trained multiple binary classifiers, or decoders, to distinguish between fMRI data obtained at each lag from ones obtained during a neutral state in which subjects were not experiencing humor. As a result, in the right dorsolateral prefrontal cortex and the right temporal area, the decoders showed significant classification accuracies even at two seconds ahead of the humor onsets. Furthermore, given a time series of fMRI data obtained during movie viewing, we found that the decoders with significant performance were also able to predict the upcoming humor events on a volume-by-volume basis. Taking into account the hemodynamic delay, our results suggest that the upcoming humor events are encoded in specific brain areas up to about five seconds before the awareness of experiencing humor. Our results provide evidence that there exists a mental state lasting for a few seconds before actual humor perception, as if a viewer is expecting the future humorous events. PMID:24324656

    How strongly does humor (i.e., the construct-relevant content) in the Humor Styles Questionnaire (HSQ; Martin et al., 2003) determine the responses to this measure (i.e., construct validity)? Also, how much does humor influence the relationships of the four HSQ scales, namely affiliative, self-enhancing, aggressive, and self-defeating, with personality traits and subjective well-being (i.e., criterion validity)? The present paper answers these two questions by experimentally manipulating the 32 items of the HSQ to only (or mostly) contain humor (i.e., construct-relevant content) or to substitute the humor content with non-humorous alternatives (i.e., only assessing construct-irrelevant context). Study 1 ( N = 187) showed that the HSQ affiliative scale was mainly determined by humor, self-enhancing and aggressive were determined by both humor and non-humorous context, and self-defeating was primarily determined by the context.

Study 2 ( N = 261) showed that the relationships of the HSQ scales to the Big Five personality traits and subjective well-being (positive affect, negative affect, and life satisfaction) were consistently reduced (personality) or vanished (subjective well-being) when the non-humorous contexts in the HSQ items were controlled for.

    To measure the nitric oxide (NO) levels of aqueous humor in rabbits after photorefractive keratectomy (PRK) and to evaluate the alterations of NO levels according to the PRK surgery steps, ablation depth, and time. Fifty eyes of 25 New Zealand white rabbits were included in the study. One eye was later randomly excluded from the study in order to equalize the number of eyes in groups. Eyes were divided into seven groups, each comprising seven eyes: unwounded control (Group 1), epithelial scrape (Group 2; aqueous humor samples taken at the 4th hour), superficial PRK (Group 3; samples taken at the 4th hour), deep PRK (Group 4; samples taken at the 4th hour), epithelial scrape (Group 5; samples taken at the 24th hour), superficial PRK (Group 6; samples taken at the 24th hour), and deep PRK (Group 7; samples taken at the 24th hour). The corneal epithelium was mechanically removed in surgical groups. The authors performed superficial corneal ablation (59 microm) in Groups 3 and 6 and deep corneal ablation (99 microm) in Groups 4 and 7. Aqueous humor samples were taken at the 4th hour (Groups 2-4) or 24th hour (Groups 5-7) after corneal surgeries. NO measurements were performed indirectly by using the Griess reaction with a spectrophotometer. Aqueous humor NO levels 4 hours after corneal surgery were statistically significantly lower than the control group (p0.05). At the 24th hour, the deep PRK group had significantly lower NO levels than both the control group and Groups 5 and 6 (p0.05) but remained stable at lower levels in deep PRK groups (p<0.05). Corneal surgery caused low NO levels in aqueous humor 4 hours after surgery. However, 24 hours after surgery, NO levels normalized following epithelial scrape and superficial PRK and were stable at lower levels in the deep PRK group. Complications of deep PRK application are possibly induced by low NO existence in the aqueous humor.

    Those who work with human trauma often use humor to handle job stressors. Research has demonstrated that lighthearted humor is related to lower secondary traumatic stress scores, while gallows humor has the inverse relationship. This work explores how three types of humor relate to secondary traumatic stress: (a) humor at the expense of victims, (b) humor at the expense of offenders, and (c) humor containing sexual innuendo. Internet crimes against children taskforce personnel completed questionnaires about secondary traumatic stress and coping techniques. Humor at the expense of victims was rarely used, but when it was, it was indicative of higher secondary traumatic stress. There were no relationships between secondary traumatic stress and the use of humor at the expense of offenders or humor containing sexual innuendo.

    Full Text Available Some animated movies use humor to capture the full attention of its audience. In so doing, the movie’s messages have become a great concern for many theorists and critics by virtue of the idea that a movie can be a repository of ideologies meant to construct a certain type of easy-going and noncritical audience. This paper, therefore, takes the example of Max Fleischer’s Popeye the Sailor Meets Ali Baba and his Forty Thieves (1937 and Robert Clampett’s Ali Baba Bound (1941 as its case studies aiming at spotting the different manifestations of humor, taking Arabs as its subject-matter, becoming a leaked ideology and taming the discourse that is amplified, manipulated, and delivered to the Western public in unwarrantable ways compared to the imagery of Westerners.

  10. Mother, melancholia, and humor in Erik H. Erikson's earliest writings.

    Capps, Donald

    2008-09-01

    Erik H. Erikson wrote three articles when he was in his late-twenties and an up-and-coming member of the psychoanalytic community in Vienna. At the time he wrote these articles, he was in a training psychoanalysis with Anna Freud, teaching at the Heitzing School in Vienna, and learning the Montessori method of teaching. These articles focus on the loss of primary narcissism and the development of the superego (or punitive conscience) in early childhood, especially through the child's conflict with maternal authority. They support the idea that melancholia, with its internalized rage against the mother, is the inevitable outcome of the loss of primary narcissism. I note, however, that the third of these articles makes a case for the restorative role of humor, especially when Freud's view that humor is a function of the superego is taken into account.

    The immune system is an important regulatory mechanism affected by spaceflights. In a previous work, we performed a first study of the humoral immune response induced by the immunization of Pleurodeles waltl during a 5 months stay onboard the Mir space station. This analysis indicated that heavy-chain variable domains of specific IgM are encoded by genes of the VHII and VHVI families. However, the contributions of these two families to IgM heavy-chains are different in flown animals [1]. To better understand this immune response modification, we have now determined how individual VH genes have been used to build specific IgM binding sites in animals immunized on earth or in space. This new study revealed quantitative and qualitative modifications in VH genes expression. These data confirm that a spaceflight might affect the humoral response.

    Full Text Available As manifestações otorrinolaringológicas nas doenças reumáticas representam um desafio diagnóstico para o reumatologista, o otorrinolaringologista e o médico generalista. Comumente, sintomas otorrinolaringológicos representam um sinal inicial de uma doença assintomática ou uma desordem auto-imune não diagnosticada, que freqüentemente exige um imediato e agressivo tratamento imunossupressor. Distúrbios auditivos podem ser vistos em pacientes com lúpus eritematoso sistêmico (LES, granulomatose de Wegener (GW, policondrite recidivante (PR, poliarterite nodosa, síndrome de Cogan, síndrome de Sjögren e menos freqüentemente na síndrome de Churg-Strauss e doença de Behçet. O nariz e seios paranasais são variavelmente afetados durante o curso da GW, síndrome de Churg-Strauss, PR e sarcoidose. Ulcerações mucosas recorrentes são comuns no LES e doença de Behçet. Xerostomia é uma manifestação comum da síndrome de Sjögren primária e secundária; aumento da glândula salivar pode ser visto nesses pacientes, assim como nos pacientes com sarcoidose. A articulação cricoaritenóide pode ser envolvida durante o curso da artrite reumatóide, espondilite anquilosante e gota; alterações osteoartríticas também têm sido descritas. Disfunção do nervo trigeminal pode ocorrer em pacientes com síndrome de Sjögren, esclerose sistêmica, LES e doença mista do tecido conjuntivo.

    Humor is found to be an essential element of creative thinking in Western culture. In Eastern culture, however, the relationship between creativity and humor is ambivalent. This study examined the relationship among humor styles, creative personality traits, and creative thinking abilities. A sample of 118 Chinese undergraduates in Hong Kong was recruited to complete the Humor Styles Questionnaire, the three Creative Personality subscales of the Chinese Personality Assessment Inventory-2 (CPAI-2), and the Verbal Test of the Wallach-Kogan Creativity Tests. Results show that humor styles are uncorrelated with creative thinking abilities of flexibility, fluency, and originality, but affiliative humor and aggressive humor are correlated with creative personality traits of novelty and diversity. A hierarchical multiple regression shows that both humor styles and creative personality traits of novelty and diversity account for non-significant variance on creative thinking abilities. These findings largely support a hypothesized non-association between humor styles and creative measures. They also pose a sharp contrast to findings obtained in the West, in which humor styles are typically correlated with both creative thinking abilities and creative personality traits.

    Full Text Available Past research suggests that sense of humor may play a role in anxiety. The present study builds upon this work by exploring how individual differences in various humor styles, such as affiliative, self-enhancing, and self-defeating humor, may fit within a contemporary research model of anxiety. In this model, intolerance of uncertainty is a fundamental personality characteristic that heightens excessive worry, thus increasing anxiety. We further propose that greater intolerance of uncertainty may also suppress the use of adaptive humor (affiliate and self-enhancing, and foster the increased use of maladaptive self-defeating humor. Initial correlational analyses provide empirical support for these proposals. In addition, we found that excessive worry and affiliative humor both served as significant mediators. In particular, heightened intolerance of uncertainty lead to both excessive worry and a reduction in affiliative humor use, which, in turn, increased anxiety. We also explored potential humor mediating effects for each of the individual worry content domains in this model. These analyses confirmed the importance of affiliative humor as a mediator for worry pertaining to a wide range of content domains (e.g., relationships, lack of confidence, the future and work. These findings were then discussed in terms of a combined model that considers how humor styles may impact the social sharing of positive and negative emotions.

    2018-01-27

    Little is known about humor and purpose in life in people with dementia. Although having a sense of humor is typically associated with positive psychological outcomes, recent evidence suggests that outcomes may vary depending on whether the humor being used is adaptive versus maladaptive. The goal of this study was to determine whether humor styles are predictive of purpose in life in people with dementia. Questionnaires were verbally administered to people with mild-to-moderate dementia to measure humor styles and purpose in life. Adaptive humor styles were associated with purpose in life whereas maladaptive humor styles were not. Having a sense of humor in dementia may be associated with a stronger sense of purpose in life, but it depends on the type of humor used. Results are discussed in the context of understanding the role of humor in the daily lives of people with dementia and implications for care. © The Author(s) 2018.

    2016-08-01

    Since the start of the 21st century, the investigation of various psychological aspects of humor and laughter has become an increasingly prominent topic of research. This growth can be attributed, in no small part, to the pioneering and creative work on humor and laughter conducted by Professor Rod Martin. Dr. Martin's research interests in humor and laughter began in the early 1980s and continued throughout his 32 year long career as a professor of clinical psychology at the University of Western Ontario. During this time, Dr. Martin published numerous scholarly articles, chapters, and books on psychological aspects of humor and laughter. Professor Martin has just retired in July 2016, and in the present interview he recounts a number of research highlights of his illustrious career. Dr. Martin's earliest influential work, conducted while he was still in graduate school, stemmed from an individual difference perspective that focused on the beneficial effects of sense of humor on psychological well-being. This research focus remained evident in many of Professor Martin's subsequent investigations, but became increasingly refined as he developed several measures of different components of sense of humor, including both adaptive and maladaptive humor styles. In this interview, Dr. Martin describes the conceptualization, development and use of the Humor Styles Questionnaire, along with suggestions for future research and development. In doing so, he also discusses the three main components of humor (i.e., cognitive, emotional and interpersonal), as well as the distinctions and similarities between humor and laughter. Further highlights of this interview include Professor Martin's comments on such diverse issues as the genetic versus environmental loadings for sense of humor, the multifaceted nature of the construct of humor, and the possible limitations of teaching individuals to use humor in a beneficial manner to cope with stress and enhance their social and

  4. Investigating vision in schizophrenia through responses to humorous stimuli

    Full Text Available The visual environment of humans contains abundant ambiguity and fragmentary information. Therefore, an early step of vision must disambiguate the incessant stream of information. Humorous stimuli produce a situation that is strikingly analogous to this process: Funniness is associated with the incongruity contained in a joke, pun, or cartoon. Like in vision in general, appreciating a visual pun as funny necessitates disambiguation of incongruous information. Therefore, perceived funniness of visual puns was implemented to study visual perception in a sample of 36 schizophrenia patients and 56 healthy control participants. We found that both visual incongruity and Theory of Mind (ToM content of the puns were associated with increased experienced funniness. This was significantly less so in participants with schizophrenia, consistent with the gestalt hypothesis of schizophrenia, which would predict compromised perceptual organization in patients. The association of incongruity with funniness was not mediated by known predictors of humor appreciation, such as affective state, depression, or extraversion. Patients with higher excitement symptoms and, at a trend level, reduced cognitive symptoms, reported lower funniness experiences. An open question remained whether patients showed this deficiency of visual incongruity detection independent of their ToM deficiency. Humorous stimuli may be viewed as a convenient method to study perceptual processes, but also fundamental questions of higher-level cognition.

    Full Text Available The effects of bimatoprost on aqueous humor dynamics were quantified in monkey eyes. Uveoscleral outflow was measured by the anterior chamber perfusion method, using FITC-dextran. Total outflow facility was determined by the two-level constant pressure method. Aqueous flow was measured with a scanning ocular fluorophotometer. Uveoscleral outflow was 0.96±0.19 L min−1 in vehicle-treated eyes and 1.37±0.27 L min−1 (=6; <.05 in eyes that received bimatoprost 0.01% b.i.d. × 5 days. Bimatoprost had no effect on total outflow facility, which was 0.42±0.05 L min−1 at baseline and 0.42±0.04 L min−1 after bimatoprost treatment. Bimatoprost had no significant effect on aqueous humor flow. This study demonstrates that bimatoprost increases uveoscleral outflow but not total outflow facility or aqueous humor flow, indicating that it lowers intraocular pressure in ocular normotensive monkeys by a mechanism that exclusively involves uveoscleral outflow.

    Full Text Available In this paper, we focus on the mnemonic relationship between Cartas Chilenas, a work of the eighteenth century attributed to Thomas Antônio Gonzaga, and Respostas às Cartas Chilenas, written in 1991 by Napoleão Valadares. Working in the context of language studies, we adopt a route of discursive description and interpretation of this relationship, which highlights aspects of literary, ociopolitical and cultural memories. For this, we will use the notions of dialogism (Bakhtin and memory (Charaudeau, highlighting its three dimensions – the memory of signs, the memory of situations and the memory of discourse. We realize that the inclusion at memory of Respostas às Cartas Chilenas made to emerge - amid the satirical tradition and the denunciations of bad government - a set of sociopolitical values staged as arguments counter the government of President Fernando Collor de Mello. Thus, the relationship between mnemonic in these works contributes to the design the persuasive project of Valadares.

    Full Text Available In the book "Eat Right For Your Type" the author Peter J. D'Adamo writes that the O blood type was the first blood type to appear in humans and affirms that the blood groups are the key to the immune system. Some recent phylogenetic network studies in humans and non-human primates implies that the A gene represents an ancient form of the ABO genes. Relationships between blood groups and infectious and noninfectious diseases and immunodeficiency abnormalities have also been reported in the literature. As D'Adamo's propositions seem to be in opposition with the current knowledge, we present in this paper some comments about the genetics and the evolution of the ABO blood group genes and some links between this blood system and the functioning of the immune system.Peter J. D'Adamo, autor do livro "Eat Right For Your Type", escreve que o grupo O representa o primeiro tipo sangüíneo que surgiu nos humanos e também afirma que os grupos sangüíneos constituem as bases do sistema imune. Recentes estudos filogenéticos realizados em primatas humanos e não humanos estabeleceram que o gene A representa a forma ancestral dos genes que ocupam o locus ABO. Associações entre os grupos sangüíneos ABO, doenças infecciosas, não infecciosas e imunodeficiências também foram relatadas. Diante das proposições do autor, as quais se opõem às informações resultantes de recentes estudos moleculares e filogenéticos, nossa intenção é apresentar algumas reflexões sobre a genética e a evolução dos genes do sistema ABO e as conexões deste sistema com o sistema imune.

  17. Humor in the eye tracker: attention capture and distraction from context cues.

    Strick, Madelijn; Holland, Rob W; Van Baaren, Rick; Van Knippenberg, Ad

    2010-01-01

    The humor effect refers to a robust finding in memory research that humorous information is easily recalled, at the expense of recall of nonhumorous information that was encoded in close temporal proximity. Previous research suggests that memory retrieval processes underlie this effect. That is, free recall is biased toward humorous information, which interferes with the retrieval of nonhumorous information. The present research tested an additional explanation that has not been specifically addressed before: Humor receives enhanced attention during information encoding, which decreases attention for context information. Participants observed humorous, nonhumorous positive, and nonhumorous neutral texts paired with novel consumer brands, while their eye movements were recorded using eye-tracker technology. The results confirmed that humor receives prolonged attention relative to both positive and neutral nonhumorous information. This enhanced attention correlated with impaired brand recognition.

    Research has indicated that HIV service providers commonly use humor to cope with work-related stress; however, little is known about the forms and functions of humor used by these professionals. In this study, 25 HIV service providers from five AIDS service organizations were interviewed about their use of humor. Participants described five primary types of humor as prevalent within AIDS service organizations and noted that humor served a variety of functions, which were either adaptive or maladaptive. Adaptive functions included boosting morale and reducing tension, whereas maladaptive functions ranged from masking emotions to alienating certain groups. Results emphasized the importance of context in the study of humor use and the need for continued investigations of the stress and coping of HIV service providers.

    2016-01-01

    This study examined the relationship among humor coping, optimism, neuroticism, and depression in a sample of breast cancer survivors and matched control participants. Breast cancer survivors reported marginally lower levels of depression than the controls. In both groups, humor coping was not related to depression, optimism, or neuroticism, but depression was correlated negatively with optimism and positively with neuroticism. In the breast cancer group, humor coping was correlated with the coping subscales of self-distraction, positive reframing, planning, and active coping. In the control group, humor coping was correlated with the coping sub-scales of self-distraction, positive reframing, planning, venting, and using instrumental support. These results suggest either that humor coping is not a stable variable or that whether humor is a positive or negative coping technique depends partly on the population under study.

    Humor has its own place in the context of medicine. Nevertheless, its acceptance by terminal stage patients and health-care professionals has not been studied in depth and is not free from controversy. To understand the significance, appropriateness, and pertinence of the use of humor in palliative care and to analyze its applicability. A narrative systematic review was undertaken and included in PROSPERO. Online searches were carried out on PUBMED, PSYCINFO, EBSCO (CINHAL), EMBASE, SCIELO, SCOPUS, TESEO, WEB of SCIENCE, and COCHRANE between their launch date and December 31, 2015, complemented with manual searches with queries to experts. A total of 156 studies were identified, which were then filtered in pairs by means of an established hierarchy, selecting studies that discussed the use of humor specifically in palliative care from all perspectives and designs, and finally published in Spanish, English, French, or Portuguese. Critical reading of all the selected studies took place, with no exclusions due to quality evaluation. Thirty-four studies were included. Five main topics were identified: (1) definition of humor, (2) use and functions of humor in palliative care, (3) how to use humor, (4) when not to use humor, and (5) humor before and after the diagnosis of terminal illness. Humor plays an unquestionable role in palliative care, but its use needs training and appropriate use.

  3. Sex differences in preferences for humor: a replication, modification, and extension.

    Hone, Liana S E; Hurwitz, William; Lieberman, Debra

    Evolutionary-minded scientists have proposed that humor is a sexually selected trait in men that signals mate quality. Indeed, women tend to prefer men who make them laugh and men tend to prefer women who laugh at their jokes. However, it is unclear how robust this pattern is. Here we report a replication of one of the first studies (Bressler, Martin, and Balshine, 2006) to examine the sex differences in preferences for humor receptivity versus humor production. We replicate Bressler et al.'s (2006) findings that men prefer women who are receptive to their humor whereas women prefer men who produce humor. These findings held even after we modified Bressler et al.'s questionnaire for better conceptual validity. Furthermore, using a separate measure designed to assess trade-offs, we found that men viewed humor receptivity as a necessity and humor production as a luxury when they were asked to create an ideal long-term partner. For women, it was just the opposite. These results bolster the claim that sexual selection has shaped sex differences regarding preferences for a prospective mate's sense of humor and that what one means by "sense of humor" can vary.

  4. Does humor in radio advertising affect recognition of novel product brand names?

    2001-04-01

    The authors proposed that item selection during shopping is based on brand name recognition rather than recall. College students rated advertisements and news stories of a simulated radio program for level of amusement (orienting activity) before participating in a surprise recognition test. Humor level of the advertisements was varied systematically, and content was controlled. According to signal detection analysis, humor did not affect the strength of recognition memory for brand names (nonsense units). However, brand names and product types were significantly more likely to be associated when appearing in humorous advertisements than in nonhumorous advertisements. The results are compared with prior findings concerning humor and recall.

    In the ongoing discussion regarding the aetiopathogenesis of equine recurrent uveitis (ERU) it was the aim of the present study to elucidate the relationship of leptospira infection and ERU. In a population of 225 horses leptospira were examined in vitreous humor by culture and leptospira antibody were detected in vitreous humor and serum samples. Preoperative serum samples were collected from 221/225 ERU patients of different age, gender and breed. Undiluted vitreous humor was aseptically taken from 198/225 patients that underwent pars plana vitrectomy at the beginning of surgery and from 27/225 patients' eyeball after enucleation: Serum and vitreous humor were tested for specific leptospiral antibodies by microscopic agglutination test (MAT). Furthermore, vitreous humor was examined by culture. 20 patients which were euthanized due to a live-threatening disease other than ERU served as a control group. A total of 127/221 (57.5%) horses had serum antibodies (≥ 1:100). Most frequently antibodies against L. interrogans serovar Grippotyphosa were detected (79/127), followed by L. interrogans serovar lcterohaemorrhagiae (34/127) and L. interrogans serovar Bratislava (29/127). Only 79/225 horses (35.1%) had leptospiral antibodies in vitreous humor, in which L. interrogans serovar Grippotyphosa (67/79) was identified most frequently followed by L. interrogans serovar Pomona (18/79) and L. interrogans serovar lcterohaemorrhagiae (8/79) which was identified as single or multiple reaction. Isolation of leptospira from vitreous humor was positive in 34/212 horses (16%). 10/20 control horses had a positive antibody titer against leptospira in serum and 2/20 horses in vitreous humor, whereas there was no leptospira detected in culture. The result of 84% negative cultures from vitreous humor of 212 ERU patients is decisive for the diagnosis and therapy of ERU.

    Considering the effects of gamma radiation on proteins and the ability of immune system to recognize modified macromolecules, we have identified the major cytokines involved in immune response of B10.PL, BALB/c and Knockout- IFN{gamma} mice exposed to native or irradiated bothropstoxin-1 (BTHX-1), in the presence and absence of scavengers substances. In order to evaluate possible molecule structural modifications after being irradiated ({sup 60}Co gamma rays), bothropstoxin-1 was submitted to SDS-PAGE analyses. Our results indicated that irradiation process has promoted modifications in the BTHX-1 molecule, however, in the presence of scavengers and even after irradiation process, the main band of toxin was preserved (14 kDa). Sera of animals immunized with the native or irradiated toxin, in the presence or not of scavengers, were analyzed in order to quantify specific isotopes. While the native BTHX-1 induced a predominant Th2 response, the irradiated toxin apparently promoted a switch towards a Th1 pattern. The toxin, when irradiated in the presence of t-butanol, induced to a lower production of IgG2b (Th1 response) if compared with the irradiated toxin without scavengers. We also performed a Real-time PCR to quantify the expression of cytokines IFN-{gamma}, IL-2, IL-4 and IL-10 in spleen cells from mice. The cells of B10.PL and BALB/c mice immunized with native BTHX-1 and in vitro stimulated with irradiated toxin, showed higher expression of IFN-{gamma} and IL-2 (Th1 response) than the control sample. The cells of Knockout-IFN{gamma} mice immunized with native BTHX-1 showed higher expression of IL-4 (Th2 response). The cells obtained of B10.PL and BALB/c mice immunized with BTHX-1 + t-butanol, showed higher expression of IL-4 and IL-10, respectively. These facts reinforce the involvement of OH in the modulation of immune response against the irradiated toxin. (author)

    The adaptive immune response forms the basis of allograft rejection. Its weapons are direct cellular cytotoxicity, identified from the beginning of organ transplantation, and/or antibodies, limited to hyperacute rejection by preformed antibodies and not as an allogenic response. This resulted in allogenic response being thought for decades to have just a cellular origin. But the experimental studies by Gorer demonstrating tissue damage in allografts due to antibodies secreted by B lymphocytes activated against polymorphic molecules were disregarded. The special coexistence of binding and unbinding between antibodies and antigens of the endothelial cell membranes has been the cause of the delay in demonstrating the humoral allogenic response. The endothelium, the target tissue of antibodies, has a high turnover, and antigen-antibody binding is non-covalent. If endothelial cells are attacked by the humoral response, immunoglobulins are rapidly removed from their surface by shedding and/or internalization, as well as degrading the components of the complement system by the action of MCP, DAF and CD59. Thus, the presence of complement proteins in the membrane of endothelial cells is transient. In fact, the acute form of antibody-mediated rejection was not demonstrated until C4d complement fragment deposition was identified, which is the only component that binds covalently to endothelial cells. This review examines the relationship between humoral immune response and the types of acute and chronic histological lesion shown on biopsy of the transplanted organ.

A audiometria tonal é o exame padrão-ouro; no entanto, nem sempre pode ser conclusiva, principalmente em crianças e adultos não colaborativos. Objetivo: Comparar os limiares auditivos da RAEE aos da audiometria tonal em indivíduos com audição normal. Materiais e métodos: Foram incluídos neste estudo prospectivo de corte transversal 26 adultos (52 orelhas, de ambos os gêneros, com audiometria normal e sem queixas otológicas. Os pacientes foram submetidos a anamnese, otomicroscopia, audiometria e imitanciometria. A seguir, realizou-se avaliação de respostas auditivas de estado estável. Os resultados obtidos foram analisados estatisticamente e comparados entre si. Resultados: A diferença entre os limiares (em dB NA obtidos em ambos os exames para cada frequência testada foi de 7,12 dB para 500 Hz; 7,6 dB para 1000 Hz; 8,27 dB para 2000 Hz e 9,71 dB para 4000 Hz, com limiares mais elevados na RAEE, em todas as frequências. Não houve diferença estatística entre as médias para cada frequência testada. Conclusão: Os limiares obtidos na RAEE foram comparáveis aos da audiometria tonal em indivíduos normouvintes; entretanto, não deve ser usado como único método de avaliação auditiva.

    Full Text Available Resumo: Objetivo: Comparar respostas psicobiológicas e perceptuais agudas em homens normotensos e hipertensos, após sessões de treinamento resistido com diferentes níveis de interação social: treinamento resistido manual e treinamento resistido com pesos livres. Método: Vinte e seis homens (14 normotensos, 40.29 ± 8.63 anos, índice de massa corporal: 26.53 ± 5.24 kg/m2; 12 hipertensos, 46.00 ± 9.13 anos, índice de massa corporal: 32.51 ± 4.41 kg/m2 foram submetidos a sessões únicas de treinamento resistido manual e treinamento resistido com pesos livres. Foram aferidos ansiedade e humor nos momentos pré e pós‐intervenção. Adicionalmente, foi aplicado um questionário para identificar pontos positivos e negativos das intervenções. Para análise dos resultados, utilizou‐se ANOVA two‐way e post‐hoc de Bonferroni. Adotou‐se nível de significância de 5%. Para ansiedade e humor, também foi utilizada análise do tamanho do efeito. A análise do questionário qualitativo considerou a frequência de pontos positivos e negativos relatados pelos voluntários. Resultados: Nenhuma intervenção foi eficiente em diminuir significativamente os valores iniciais de ansiedade; no entanto, o treinamento resistido manual apresentou maior magnitude de diminuição no tamanho do efeito. Nos fatores negativos do humor, o treinamento resistido manual também proporcionou maiores magnitudes para diminuição no tamanho do efeito. O treinamento resistido manual teve mais pontos positivos e menos pontos negativos mencionados pela amostra, em relação ao treinamento resistido com pesos livres. Conclusão: O nível de interação social parece influenciar positivamente as respostas psicobiológicas agudas do treinamento resistido, e o treinamento resistido manual parece ser uma alternativa viável para esse objetivo. Resumen: Objetivo: Comparar las respuestas psicobiológicas y percepcionales agudas en hombres normotensos e

    Full Text Available In 2010, there were estimated to be approximately 60.5 million people with glaucoma. This number is expected to increase to 79.6 million by 2020. In 2010, there were 8.4 million people with bilateral blindness caused by glaucoma, and this number is expected in increase to 11.2 million by 2020. Filtering implants are special devices that have been developed to reduce intraocular pressure in patients with refractory glaucoma. The success rate of these implants is relatively low, and they continue to fail over time. To avoid failure caused by the formation of scar tissue around the implants, attempts have been made to drain the aqueous humor to various sites, including the venous system, lacrimal sac, sinuses, and conjunctival fornix. Recently, a system to shunt aqueous humor from the anterior chamber to the peritoneum has been developed. The surgical technique involved in this system is a modification of the technique currently used by neurosurgeons for the treatment of hydrocephalus. We present the first case operated using this technique.

    It has often been asserted, by both men and women, that men are funnier. We explored two possible explanations for such a view, first testing whether men, when instructed to be as funny as possible, write funnier cartoon captions than do women, and second examining whether there is a tendency to falsely remember funny things as having been produced by men. A total of 32 participants, half from each gender, wrote captions for 20 cartoons. Raters then indicated the humor success of these captions. Raters of both genders found the captions written by males funnier, though this preference was significantly stronger among the male raters. In the second experiment, male and female participants were presented with the funniest and least funny captions from the first experiment, along with the caption author's gender. On a memory test, both females and males disproportionately misattributed the humorous captions to males and the nonhumorous captions to females. Men might think men are funnier because they actually find them so, but though women rated the captions written by males slightly higher, our data suggest that they may regard men as funnier more because they falsely attribute funny things to them.

  17. The imperative of humor in the portfolio of communication strategies

    2017-12-01

    Communicating geophysics often challenges scientists because the results often challenge the users of the information. We can bring good news, but far more often we are warning about impending disaster from hurricane or earthquake, landslide or sea-level rise. Much of our work is publicly funded, and thus carries the obligation to make the results useful, not just available. Our leading responsibility is to get the research right, because everything else rests on that foundation. But, beyond that, scholarship shows clearly that we must adopt multiple communication paths, with a wide range of spokespersons and techniques. Humor can ease a challenging situation, capture the attention of the unengaged, and make things easier for all involved, including the occasionally stressed scientists. The juxtaposition of a light touch with heavy science is often worthwhile for those willing to try it. Bungy jumping for science, or warning about tsunamis with Johnny Cash songs, may not be for everyone, but many geophysicists can come up with better, humorous ways to really connect, helping fulfill their obligation to the public.

    Full Text Available Speech humor in MTGW program is assumed as a "good practice" of pragmatic strategy to entertain, inspire and motivate audience. The focus and objective of this study is to get a description of the pragmatic strategy of harmonizing word choice, sentence, and humorous language in MTGW program. How pragmatic strategies have implications for the use of words, sentences, and language styles so that the audience feel entertained and laughed. This research uses desciptive qualitative approach. Data in the form of humorous languages is collected by listening and recording. The method of analysis is padan and agih. The word data, sentence, and style of the humorous language are linked and compared to other words, sentences, and language styles in terms of humorous sense between sentences produced and comparator sentences. As a result, the pragmatic strategy MT uses in the MTGW program on Metro TV is to harmonize between lingual units of words, sentences, and language styles with humor and courtesy. MT uses a locusive and illocusive strategy with humorous tones and politeness in choosing, organizing and producing every word, sentence, and style of humor. Through the choice of words, sentences, and language style, the MT uses pragmatic strategies in conveying his message as a motivator and the perlocutionary effect is that the audience becomes interested or entertained.

  4. Sex Differences in Preferences for Humor: A Replication, Modification, and Extension

    Directory of Open Access Journals (Sweden)

    Liana S. E. Hone

    2015-01-01

    Full Text Available Evolutionary-minded scientists have proposed that humor is a sexually selected trait in men that signals mate quality. Indeed, women tend to prefer men who make them laugh and men tend to prefer women who laugh at their jokes. However, it is unclear how robust this pattern is. Here we report a replication of one of the first studies (Bressler, Martin, and Balshine, 2006 to examine the sex differences in preferences for humor receptivity versus humor production. We replicate Bressler et al.'s (2006 findings that men prefer women who are receptive to their humor whereas women prefer men who produce humor. These findings held even after we modified Bressler et al.'s questionnaire for better conceptual validity. Furthermore, using a separate measure designed to assess trade-offs, we found that men viewed humor receptivity as a necessity and humor production as a luxury when they were asked to create an ideal long-term partner. For women, it was just the opposite. These results bolster the claim that sexual selection has shaped sex differences regarding preferences for a prospective mate's sense of humor and that what one means by “sense of humor” can vary.

    2014-08-01

    Full Text Available This study investigated the psychometric properties of the Humor Styles Questionnaire (HSQ and the relation between humor and psychological well-being within the context of Italy. A total of 293 (178 females, 115 males Italian high school and undergraduate university students – whose ages ranged from 14 to 25 years – completed the Italian versions of the HSQ and the Ryff’s Psychological Well-Being scales (RPWB. The HSQ scale reliabilities were generally acceptable, and intercorrelations among the scales were rather low; the confirmatory factor analysis supported the four-factor structure. Males reported significantly more use of Aggressive humor than did females; no differences were found between adolescents and young adults in the use of humor styles. Affiliative and Self-enhancing humor styles were positively associated with the six dimensions of the RPWB, whereas Self-defeating humor was negatively correlated with the RPWB scales. SEM analysis showed a significant and positive relationship between humor as measured by the HSQ and psychological well-being as assessed by the RPWB. Overall, the findings supported the theoretical structure and usefulness of the HSQ in an Italian context and the differential role of humor components in the various dimensions of psychological well-being.

    2014-03-01

    The purpose of this study was to describe humor and laughter in persons with cognitive impairment (PWCI) and caregivers who were recalling a shared experience in a focus group. Twenty participants attended an Art Engagement Activity at the Andy Warhol Art Museum, which included a guided tour and an art project. All PWCI had medically diagnosed cognitive disorders and all caregiver participants did not. Four focus groups were conducted and transcripts of audio-recorded sessions were transferred to a qualitative software program. Words, phrases, and episodes of humor and laughter were used to construct codes, which were refined during group analysis using constant comparison. Humor and laughter were present in all four focus groups. Emerging themes of humor included silliness, sarcasm, and commenting about hardships of dementia. Laughter was identified in segments with and without humor. Some PWCI were unable to follow social cues. Humor and laughter played a role in creating a safe social environment. PWCI were able to engage in humor during social interactions, yet some had difficulty recognizing social cues. Further study may reveal roles of humor and laughter in adaptation to cognitive decline and holistic interventions for improved quality of life.

    2015-11-11

    The aim of this study was to evaluate the influence of transcranial direct current stimulation targeting the left temporoparietal junction (TPJ) on humor appreciation during a dynamic video rating task. In a within-participants design, we targeted the left TPJ with anodal, cathodal, or no transcranial direct current stimulation, centered at electrode site C3 using a 4×1 targeted stimulation montage. During stimulation, participants dynamically rated a series of six stand-up comedy videos for perceived humor. We measured event-related (time-locked to crowd laughter) modulation of humor ratings as a function of stimulation condition. Results showed decreases in rated humor during anodal (vs. cathodal or none) stimulation; this pattern was evident for the majority of videos and was only partially predicted by individual differences in humor style. We discuss the possibility that upregulation of neural circuits involved in the theory of mind and empathizing with others may reduce appreciation of aggressive humor. In conclusion, the present data show that neuromodulation of the TPJ can alter the mental processes underlying humor appreciation, suggesting critical involvement of this cortical region in detecting, comprehending, and appreciating humor.

    2017-06-01

    Three studies examined humor and adjustment to stressful events. In Study 1, patients with fibromyalgia syndrome ( N = 22) reported on mental and physical adjustment, social interaction, and reappraisal of their illness. Dispositional humor was associated with reduced distress and fewer physical symptoms. Study 2 ( N = 109) examined undergraduates' reports of stressful events. Dispositional, self-enhancing, affiliative, and self-defeating humor showed direct effects on distress, which were mediated by social interaction and reappraisal. Moreover, dispositional and aggressive humor showed stress-buffering effects. Study 3 ( N = 105) examined undergraduates' adjustment to the September 11, 2001, attacks at 1 and 3 months postattack. At T1, affiliative humor showed a stress-buffering effect on distress. Social interaction mediated the relation of self-enhancing humor with reduced T1 distress, and mediated relations of aggressive and self-defeating humor with greater distress. Relations of T1 dispositional and self-defeating humor to changes in T2 distress were mediated by reappraisal.

  7. Humor Appreciation Involves Parametric and Synchronized Activity in the Medial Prefrontal Cortex and Hippocampus.

    Science.gov (United States)

    Iidaka, Tetsuya

    2017-12-01

    Humor perception is a ubiquitous phenomenon in human societies. In theories of humor perception, three factors, non-seriousness, social context, and incongruity, have been implicated in humor. In another theory, however, elaboration and reinterpretation of contexts are considered to play a role in eliciting humor. Although the neural correlates of humor appreciation have been investigated using neuroimaging methods, only a few studies have conducted such experiments under natural conditions. In the present study, two functional magnetic resonance imaging experiments, using a comedy movie as a stimulus, were conducted to investigate the neural correlates of humor under natural conditions. The subjects' brain activity was measured while watching and enjoying a movie. In experiment 1, a parametric analysis showed that the medial prefrontal cortex (MPFC) and hippocampus/amygdala had a positive relationship with the subjective rating of funniness. In experiment 2, intersubject correlation was analyzed to investigate synchronized activity across all participants. Signal synchronization that paralleled increased funniness ratings was observed in the MPFC and hippocampus. Thus, it appears that both parametric and synchronized activity in the MPFC and hippocampus are important during humor appreciation. The present study has revealed the brain regions that are predominantly involved in humor sensation under natural condition. © The Author 2016. Published by Oxford University Press.

    Oczkowski, Simon

    2015-05-11

    There is increasing recognition of the stress and burnout suffered by critical care workers. Physicians have a responsibility to teach learners the skills required not only to treat patients, but to cope with the demands of a stressful profession. Humor has been neglected as a strategy to help learners develop into virtuous and resilient physicians. Humor can be used to reduce stress, address fears, and to create effective health care teams. However, there are forms of humor which can be hurtful or discriminatory. In order to maximize the benefits of humor and to reduce its harms, we need to teach and model the effective and virtuous use of humor in the intensive care unit.

    To assess aqueous humor antimicrobial activity in vitro after topical 0.5% chloramphenicol application. This investigation included 63 eyes from 65 cataract surgery patients. The study group of 48 eyes received preoperatively four topical applications of 0.5% chloramphenicol. The control group of 15 eyes was given no topical applications. Aqueous humor samples were collected for in vitro antimicrobial analysis using Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, and Pasteurella multocida organisms by means of disk diffusion test. No inhibition halo was observed around all aqueous humor samples from all chloramphenicol-treated patients, irrespective of the sample quantity added to the paper disks, with no significant difference from aqueous humor from untreated control patients. Aqueous humor displayed no bactericidal effect against any of the microorganisms evaluated after topical 0.5% chloramphenicol application.

    A survey was conducted to examine the frequency, acceptability, and functions of humor between hospice palliative care volunteers and their patients, from the volunteers' perspective. Thirty-two volunteers completed the survey, which was developed for this study. The results revealed that most patients and volunteers initiated humor either "often" or "sometimes" in their interactions. Over half of the volunteers considered humor to be either "very important" or "extremely important" in their interactions with patients (42% and 13%, respectively), with the patient being the determining factor as to whether and when it is appropriate or not (ie, volunteers take their lead from their patients). Volunteers mentioned a number of functions that humor serves within their patient interactions (eg, to relieve tension, to foster relationships/connections, and to distract). Laughter and humor fulfills one of the main goals of hospice palliative care, namely, improving patients' overall quality of life.

    Previous research has shown that humorous reappraisal can reduce elicited negative emotions, suggesting that humor may be a functional strategy to cope with emotionally negative situations. However, the effect of humorous reappraisal on later memory about the emotion-eliciting situation is currently unknown, although this is crucial for more adaptive responding in future situations. To address this issue, we examined the effects of humorous reappraisal on both emotional experience and memory,...

  12. Separating content and structure in humor appreciation: The need for a bimodal model and support from research into aesthetics

    For a long time humor theorists have acknowledged that content and structure of humor (or: joke work vs. tendency, [4]; thematic vs. schematic, [12]; cognitive vs. orectic factors, [3]) have to be distinguished as two different sources of pleasure [6]. Nevertheless, against all evidence, taxonomies of humor are stuck in (serial) unimodal classifications rather than bi- or multimodal models. In- tuitive classifications of humor typically distinguish between content classes (e.g., blonde jokes,...

    In a behavioral observation study with dating couples, we examined (a) how attachment orientations predict humor use and (b) how people respond to their partners' use of humor. Couples were videotaped while trying to resolve a relationship conflict. Each discussion was rated on several theoretically relevant dimensions. Highly avoidant individuals used more aggressive humor and less affiliative humor during their discussions, whereas highly anxious individuals used more self-defeating humor. Individuals also tailored their humor use to partners who were highly anxious and distressed. Aggressive humor was received more negatively by partners who sought more care. Affiliative humor was favorably received, especially when partners were more distressed, whereas self-defeating humor elicited negative responses from highly distressed partners. Both highly anxious and avoidant individuals reacted unfavorably when they were the recipients of the humor styles they used most often. The implications of these results for our understanding of relationships and humor are discussed.

    Por otra parte y basado en el exitoso tratamiento del RAH, se ha planteado mejorar las expectativas de llegar a realizar un trasplante a los pacientes sensibilizados. Esto es posible conseguir aplicando protocolos de desensibilización que se basan en la utilización de las mismas drogas para tratar RAH, consiguiendo ampliar las posibilidades de trasplante. El éxito de éstas es relativo al tipo de protocolos y a la intensidad de la sensibilización. La sobrevida del injerto en esta situación es plausible en la gran mayoría de los casos, sin embargo existe riesgo de presentar rechazo agudo humoral, y más complejo aún es el hecho que la sobrevida a largo plazo de los injertos sigue siendo todavía desconocida.

    The main aim of this paper is to investigate speech pauses and gestures as means to engage the audience and present the humorous message in an effective way. The data consist of two speeches by the USA president Barack Obama at the 2011 and 2016 Annual White House Correspondents’ Association Dinner...... produced significantly more hand gestures in 2016 than in 2011. An analysis of the hand gestures produced by Barack Obama in two political speeches held at the United Nations in 2011 and 2016 confirms that the president produced significantly less communicative co-speech hand gestures during his speeches...... and they emphasise the speech segment which they follow or precede. We also found a highly significant correlation between Obama’s speech pauses and audience response. Obama produces numerous head movements, facial expressions and hand gestures and their functions are related to both discourse content and structure...

    The transformation of all things media and information into a dynamic environment of user access has created what seems infinite possibilities to inform the public in many different ways - as well as seemingly infinite possibilities to confuse. This talk will describe a rather non-conventional collaboration between two different creative cultures and its significance to maintaining scientific accuracy and devising strategies important to audience engagement - among them humor. While focusing on the award-winning effort ``When Things Get Small'' created by University of California Television producer R. Wargo in collaboration with condensed matter physicist I.K. Schuller and actor Adam J. Smith, with both NSF and private support, the case study provides insight into a model and modes which can be used successfully by other scientists to engage the public in what they do.

    Changes in the content and function of cell populations and subpopulations involved in the humoral response of mice to the thymus-dependent antigen were investigated. The effect was followed during a prolonged continuous exposure to 137 C gamma-emitter (total dose - 5 Gy and daily dose - 12 cGy for 22 hours) and after its termination. The data obtained give evidence for a decrease of the pool of polypotent lymphocyte precursors (CFUs), stable moderate hypoplasia of central and peripheral organs of the immune system, distinct inhibition of antibody production at the expense of reduced activity of precursors of lymphocytes, B-lymphocytes and T-helpers. In the remote post-irradiation period residual radiation damage was seen in polypotent and committed precursors of lymphocytes and T-helpers, which was responsible for the trend towards the decline of antibody production, hypoplasia in the spleen and lymph nodes being persistent

    2011-01-01

    MUC1 is a membrane-tethered mucin expressed on the ductal cell surface of glandular epithelial cells. Loss of polarization, overexpression and aberrant glycosylation of MUC1 in mucosal inflammation and in adenocarcinomas induces humoral immune responses to the mucin. MUC1 IgG responses have been associated with a benefit in survival in patients with breast, lung, pancreatic, ovarian and gastric carcinomas. Antibodies bound to the mucin may curb tumor progression by restoring cell-cell interactions altered by tumor-associated MUC1, thus preventing metastatic dissemination, as well as counteracting the immune suppression exerted by the molecule. Furthermore, anti-MUC1 antibodies are capable of effecting tumor cell killing by antibody-dependent cell-mediated cytotoxicity. Although cytotoxic T cells are indispensable to achieve anti-tumor responses in advanced disease, abs to tumor-associated antigens are ideally suited to address minimal residual disease and may be sufficient to exert adequate immune surveillance in an adjuvant setting, destroying tumor cells as they arise or maintaining occult disease in an equilibrium state. Initial evaluation of MUC1 peptide/glycopeptide mono and polyvalent vaccines has shown them to be immunogenic and safe; anti-tumor responses are scarce. Progress in carbohydrate synthesis has yielded a number of sophisticated substrates that include MUC1 glycopeptide epitopes that are at present in preclinical testing. Adjuvant vaccination with MUC1 glycopeptide polyvalent vaccines that induce strong humoral responses may prevent recurrence of disease in patients with early stage carcinomas. Furthermore, prophylactic immunotherapy targeting MUC1 may be a strategy to strengthen immune surveillance and prevent disease in subjects at hereditary high risk of breast, ovarian and colon cancer

    Full Text Available The current study explores social and emotional loneliness, social interactions and humor in a sample of Romanian students, departing from the Schiau 2016 study that found the production and social use of humor to be correlated to a reduced social loneliness in a sample of Romanian older adults. Studies indicate that loneliness can be experienced at any age, and that humor can act as a coping mechanism with life’s difficulties, triggering positive emotions. The current study replicates findings in the literature, indicating that younger adults experience less loneliness than older adults, and use more humor than older adults. Young women in the sample had a significantly more positive attitude towards humor than the men. This study has useful implications for a number of fields, including the economic and marketing sectors. The current student population represents a growing market, and studies indicate that the use of humor by service providers may intervene with any negative feelings that could cause clients to withdraw their engagement and cooperation in the service endeavor (Locke, 1996. Therefore, we argue that, for the retail and service sector, it is important to understand the different approach towards humor by the different age and gender groups discussed in this study.

    Full Text Available This quantitative study examines the correlations between humor, loneliness, gender and aging by presenting the results from a sample of eighty-three older Romanian adults, aged sixty and above. The first section of the paper is a comprehensive review of the social-psychological literature on aging, gender and humor. The second section assesses the findings generated from a study that uses the Multidimensional Sense of Humor Scale (Thorson & Powell, 1993 and the Social and Emotional Loneliness Scale for Adults – short version, (diTomaso, Brannen & Best, 2004. Building on Robert Weiss’s (1973 reflections on the differences between feelings of loneliness because of social isolation or emotional isolation, the research findings nuance –and in some cases challenge several assumptions on gender, age, and emotional and social loneliness. The findings also point to the correlation between feelings of social loneliness and the use of humor in interpersonal communications. The data collected suggests that while Romanian men may value the use of humor more than women when self-reporting, that older Romanian women tend to use humor in interpersonal situations and that there is a significant correlation between the use of this type of humor and a reduced sense of social loneliness.

  7. Infant humor perception from 3- to 6-months and attachment at one year.

    Infancy is a critical time for the development of secure attachment, which is facilitated by emotionally synchronous interactions with parents. Humor development, which includes shared laughter and joint attention to an event, emerges concurrently with attachment, but little is known regarding the relationship, if any, between humor development and attachment in the first year. Thirty 3-month-old infants were videoed at home each month until they were 6-months old while their parents attempted to amuse them. Frequency of infants' smiles and laughs served as a measure of "state humor", and the smiling/laughing subscale of the Infant Behavior Questionnaire-Revised served as a measure of "trait humor". State and trait humor were not correlated. Lower trait humor as 6 months predicted higher attachment security on the Attachment Q-sort at 12-months (r=.46), suggesting that less good-humored infants elicit greater parental engagement, which works to the benefit of attachment, or vice versa. Future studies should examine the importance of smiling and laughter as they relate to other developmental phenomena in the first year. Published by Elsevier Inc.

    Many studies include elevated activity of angiotensin-converting enzyme (ACE) in serum in sarcoidosis and in ocular sarcoidosis as well, but there are only a few analyzing ACE activities in aqueous humor. The aim of this study is to illuminate the diagnostic value of ACE in aqueous humor in patients with ocular sarcoidosis. We analyzed twenty patients with ocular sarcoidosis and 18 patients with nonocular involvement. All patients have biopsy-positive sarcoidosis of the lungs and/or mediastinal lymph nodes. Blood samples for ACE serum levels were obtained from all patients. Aqueous humor samples were taken by paracentesis with a 25-gauge needle in local anesthesia. With appropriate statistical tests, we compared ACE activity in serum and aqueous humor in patients with and without ocular sarcoidosis. The majority of our patients with ocular sarcoidosis were female (12/20), also in the group with systemic sarcoidosis and without ocular involvement (12/6). Mean age of the whole analyzed group of sarcoidosis patients was 45 ± 6 years. There is no statistically significant difference in ACE activity in serum between two groups of patients (with and without ocular sarcoidosis). There is statistically significant difference in ACE activity in aqueous humor among patients with ocular and nonocular sarcoidosis. ACE activity in aqueous humor is significantly higher in patients with ocular sarcoidosis. Increased ACE activity in aqueous humor can point to a diagnosis of ocular sarcoidosis, without the need for ocular biopsy.

  9. The role of the amygdala in incongruity resolution: the case of humor comprehension.

    A dominant theory of humor comprehension suggests that people understand humor by first perceiving some incongruity in an expression and then resolving it. This is called "the incongruity-resolution theory." Experimental studies have investigated the neural basis of humor comprehension, and multiple neural substrates have been proposed; however, the specific substrate for incongruity resolution is still unknown. The reason may be that the resolution phase, despite its importance in humor comprehension, has not been successfully distinguished from the perception phase because both phases occur almost simultaneously. To reveal the substrate, we conducted a functional magnetic resonance study using 51 healthy participants. We used a humor-producing frame of "Given A, I'd say B, because C" so as to focus on the resolution phase independently by suspending humor processing just after the perception phase. This frame allowed us to separate the two phases. Based on our results, incongruity resolution evoked positive emotion and activated the left amygdala, which is known to be related to positive emotion. On the basis of these findings, we argue that the amygdala plays an important role in humor comprehension, considering its functional role in emotional evaluation, particularly the relevance detection for incoming stimuli.

  10. Using Psychophysiological Measures to Examine the Temporal Profile of Verbal Humor Elicitation.

    Chris M Fiacconi

    Full Text Available Despite its pervasiveness in popular culture, there remains much to be learned about the psychological and physiological processes that underlie our experience of humor. In the present study, we examined the temporal profile of verbal humor elicitation using psychophysiological measures of heart rate (HR and facial electromyography (EMG. Consistent with recent prior research on cardiovascular changes to perceived humor, we found that HR acceleration was greater for jokes relative to non-jokes, and was positively related to the level of perceived humor elicited by these jokes. In addition, activity recorded from the zygomaticus major muscle that controls smiling was found to be greater for jokes relative to non-jokes. To link these physiological changes to the psychological processes that govern humor comprehension, we took the initial inflection point of the zygomatic EMG response as a marker for the onset of humor comprehension, and used this marker to probe the pattern of cardiovascular activity at this time-point. We estimated the onset of the humor response to occur during the initial HR deceleration phase, and found that jokes relative to non-jokes elicited a decreased HR response at this time-point. This result questions the previously forwarded notion that the psychological "moment of insight" that signals the start of the humor response is always associated with heightened cardiovascular activity. This discrepancy is discussed in relation to possible differences in the cognitive processes required to comprehend different forms of humor. At a broader level, our results also demonstrate the advantages of combining different psychophysiological measures to examine psychological phenomena, and illustrate how one such measure can constrain the interpretation of others.

    Full Text Available Over the last years there has been a growing interest in the study of the resources that people use from face to a problem. The interest in the study of the characteristics related to the humor has gone in increase, especially for the influence of the development of a new concept in psychology that derives in the call positive psychology (Seligman and Csikszentmihalyi, 2000; Zinder and McCullog 2000, in Martin, Puhlik-Doris, Larsen, Gray, Weir, 2003 which is centered in adaptive strengths such as optimism, faith, courage, as well as humor (Martin 2003, quoted in Martin et al., 2003. Sense of humor has been considered as an unidimensional construct (Omar, 1995 and the consequencies has been some errors in the assesment, as a result of a problem of validity. The present study seeks to introduce certain aspects that have not been considered in the past, so much the potential beneficial effects, as the deleterious forms of the sense of humor as for the psychological well-being. Four dimensions of the sense of humor were assesed (Martin, Puhlik-Doris, Larsen, Gray, Weir, 2003, version Lillo, 2006 relating to the uses or functions in everyday life and the ways of people cope (Fridenberg and Lewis, 1991, version Richaud de Minzi. 2003. They were also significant relationships among styles of humor and ways of coping that could explain the importance of the construct sense of humor, as an important resource to be used. Although it is necessary to highlight that it is not sought to embrace all the components of the sense of humor, but rather it is focused in the interpersonal functions and intrapsíquicas that adolescents use in daily life. These functions are considered most relevant to the well-being. Measuring these aspects of the humor, it is expected that they can explain a greater proportion of the variance as for the ways of people cope.

    2015-01-01

    Previous research has shown that humorous reappraisal can reduce elicited negative emotions, suggesting that humor may be a functional strategy to cope with emotionally negative situations. However, the effect of humorous reappraisal on later memory about the emotion-eliciting situation is currently unknown, although this is crucial for more adaptive responding in future situations. To address this issue, we examined the effects of humorous reappraisal on both emotional experience and memory, compared to non-humorous rational reappraisal and a non-reappraisal control condition. Replicating previous findings, humorous reappraisal reduced evoked negative valence and arousal levels very effectively, and the down-regulation of experienced negative emotions was even more pronounced after humorous compared to rational reappraisal. Regarding later memory for emotion-eliciting stimuli, both humorous and rational reappraisal reduced free recall, but recognition memory was unaffected, with memory strength being stronger after humorous than after rational reappraisal. These results indicate that humor seems to be indeed an optimal strategy to cope with negative situations because humor can help us to feel better when confronted with negative stimuli, but still allows us to retrieve stimulus information later when afforded to do so by the presence of appropriate contextual features.

However, the effect of humorous reappraisal on later memory about the emotion-eliciting situation is currently unknown, although this is crucial for more adaptive responding in future situations. To address this issue, we examined the effects of humorous reappraisal on both emotional experience and memory, compared to non-humorous rational reappraisal and a non-reappraisal control condition. Replicating previous findings, humorous reappraisal reduced evoked negative valence and arousal levels very effectively, and the down-regulation of experienced negative emotions was even more pronounced after humorous compared to rational reappraisal. Regarding later memory for emotion-eliciting stimuli, both humorous and rational reappraisal reduced free recall, but recognition memory was unaffected, with memory strength being stronger after humorous than after rational reappraisal. These results indicate that humor seems to be indeed an optimal strategy to cope with negative situations because humor can help us to feel better when confronted with negative stimuli, but still allows us to retrieve stimulus information later when afforded to do so by the presence of appropriate contextual features.

    Full Text Available The present study investigates perceived gender differences in the producion and social use of humor in the interpersonal communication of Romanian older women, aged 60 and above. The study is a qualitative investigation, based on semi-structured interviews. The aim was to understand the perceptions and motivations that women have when using humor in social interactions, and to explore the functions that humor serves in their day-to-day communication. A previous quantitative investigation found statistically significant gender differences between Romanian older men and women on a sense of humor scale, and suggested that the use of humor in interpersonal communication had stronger social benefits for women (Schiau, 2016a. Drawing on these findings, and keeping in mind other studies that discuss the different use of humor by men and women, this study aims to investigate specific gender differences in the production of humor, as perceived by the participants.

    Frankenfield, P K

    1996-01-01

    Many benefits of humor and play have been documented in the literature. The purpose of this Case Report was to assess the benefits of humor and play with a 5-year-old retinoblastoma patient in an ambulatory care setting. The use of humor in the forms of tickling, joke-telling, play on words, funny movies, silly stickers, and medical play was found to be helpful in decreasing the anxiety of a pediatric oncology patient during insertion of his Infusaport needle. This article reviews the benefits of humor and play and provides a brief discussion of the developmental aspects of humor and play theory. Implications for further nursing research in the area of humor interventions are also discussed. The promotion of appropriate humor and play use by all health care professionals is encouraged.

    Full Text Available The present study investigates the feasibility of a humor training for a subclinical sample suffering from increased stress, depressiveness, or anxiety. Based on diagnostic interviews, 35 people were invited to participate in a 7-week humor training. Evaluation measures were filled in prior training, after training, and at a 1-month follow-up including humor related outcomes (coping humor and cheerfulness and mental health-related outcomes (perceived stress, depressiveness, anxiety, and well-being. Outcomes were analyzed using repeated-measures ANOVAs. Within-group comparisons of intention-to-treat analysis showed main effects of time with large effect sizes on all outcomes. Post hoc tests showed medium to large effect sizes on all outcomes from pre to post and results remained stable until follow-up. Satisfaction with the training was high, attrition rate low (17.1%, and participants would highly recommend the training. Summarizing the results, the pilot study showed promising effects for people suffering from subclinical symptoms. All outcomes were positively influenced and showed stability over time. Humor trainings could be integrated more into mental health care as an innovative program to reduce stress whilst promoting also positive emotions. However, as this study was a single-arm pilot study, further research (including also randomized controlled trials is still needed to evaluate the effects more profoundly.

Todos os potros são expostos à doença ao nascimento, porém alguns a desenvolvem e outros não. Este artigo revisa características da resposta imune, tanto em adultos competentes quanto em potros suscetíveis ao patógeno. A resposta imune humoral é abordada, incluindo uma discussão sobre o uso do plasma hiperimune como ferramenta profilática. O papel dos mecanismos de imunidade inata na suscetibilidade de alguns potros ao R. equi é também abordado. Da mesma maneira, os componentes envolvidos na resposta cito-mediada são revisados, com atenção particular às pesquisas direcionadas ao desenvolvimento de uma vacina efetiva para ser utilizada em potros.Rhodococcus equi is an important pathogen in equine neonatology that is ubiquitous and a normal intestinal inhabitant of equines. All foals are exposed at birth, however, some foals develop disease and others do not. This article reviews concepts of the equine immune response, both in the immune adult and susceptible neonate, with respect to this pathogen. Humoral immune responses are addressed, with a discussion on the use of hyperimmune plasma as a prophylactic tool. The role that innate immune mechanisms play in the susceptibility of some foals to R. equi infection is also highlighted. Likewise, cell-mediated immune components are reviewed, with particular attention directed towards research to develop an effective vaccine for foals.

    Full Text Available In this article we provide a brief account of the uses of humor, in particular satire and ridicule, to counter extremist narratives and heroes.  We frame the appeals of humor as “rhetorical charms,” or stylistic seductions based on surprising uses of language and/or images designed to provoke laughter, disrupt ordinary arguments, and counter taken-for-granted truths, that contribute to new sources of influence to the globally wired world of terrorism.  We offer two recent examples of how the Internet in particular changed the narrative landscape in ways that offer potent evidence of uses of humor to remake extremist heroes into objects of derision.  We also caution those who would make use of humor as a strategic communication device to take into account the negative side effects and unexpected consequences that can accompany such uses.

  4. Jeff Foxworthy’s Redneck Humor and the Boundaries of Middle-Class American Whiteness

    Directory of Open Access Journals (Sweden)

    J. David Thomas

    2016-04-01

    Full Text Available Recent studies examine the use of rhetorical boundaries to produce intra-racial othering within whiteness. I expand this project by exploring the textual and social codes in Jeff Foxworthy humor that demarcate the boundaries between the redneck and the non-redneck. Such boundaries are complex, porous fault-lines that use symbolic pollution embedded in humor to stigmatize White outsiders. Social codes referencing symbolic pollution establish boundaries to define and insulate a normative, mainstream White identity from the intra-racial threat of redneck identity. This project provides a novel addition to whiteness studies by taking redneck humor analytically seriously and concludes by drawing comparisons between codes found in Foxworthy humor and those levied against rural Whites during the eugenics era.

    Full Text Available This review explores the potential overlap between the fields of nutrition and therapeutic humor, together with the role of humor as a possible tool for aiding those in whom emotions, particularly negative ones, trigger eating as a means to improve mood. We review emotional eating, obesity, and the hypothesized mechanisms of emotional eating. We then review the field of therapeutic humor and its ability to de-stress individuals, possibly through endorphin and opioid systems, both of which are also involved in eating behavior. Finally, we present a novel hypothesis that people may be trained to use humor as a “food substitute” at best, or to blunt hunger stimuli, to achieve similar advantages, without the side effect of weight gain.

  6. The effectiveness of humor in persuasion: the case of business ethics training.

    Lyttle, J

    2001-04-01

    In this study, persuasion theory was used to develop the following predictions about use of humor in persuasive messages for business ethics training: (a) cartoon drawings will enhance persuasion by creating liking for the source, (b) ironic wisecracks will enhance persuasion by serving as a distraction from counterarguments, and (c) self-effacing humor will enhance persuasion by improving source credibility. Canadian business students (N = 148) participated in 1 of 4 versions of "The Ethics Challenge," a training exercise used by the Lockheed Martin Corporation. Three versions were modified by adding or removing cartoon drawings (of cartoon characters Dilbert and Dogbert) and humorous responses (Dogbert's wisecracks). Removing the cartoon drawings had little effect on persuasiveness. Removing ironic wisecracks had more effect, and interfering with the self-effacing combination of cartoons and wisecracks had the strongest effect. The results suggest that researchers should ground their predictions in existing theory and that practitioners should differentiate among humor types.

    2013-01-01

    Full Text Available The aim of this article is to illustrate some of the mechanisms existing in political discourse which employ emotions and humor as a persuasive means. The study is based on authentic texts produced by Silvio Berlusconi. The importance of emotions and humor in political speech is viewed in the light of changes taking place in public communication due to the development of mass media and Internet, leading to, among others, ever more frequent use of the comical aspect of communication as a method of gaining and maintaining political power. That is why the use of emotions and humor in Berlusconi’s speech is analyzed as a strategic choice and a powerful instrument of political struggle. The article highlights the role of emotions and humor in creating a positive self-image of the politician.

El presente ensayo tiene como finalidad reflexionar sobre la importancia del humor pedagógico como estrategia de enseñanza aprendizaje en el aula; esto, tomando en cuenta la problemática de desmotivación y aburrimiento que sucede normalmente en la clase. Para plantear si “el enseñar contento y el aprender con alegría” pueden aumentar la eficacia en el proceso de enseñanza-aprendizaje, se abordará cómo, a pesar de las múltiples ventajas que puede aportar el humor en las aulas, se omite su empleo por la existencia de ciertos prejuicios y temores. La idea no es que los docentes hagan el papel de comediantes o payasos, sino la de mediar y acercar la clase de manera pedagógica y didáctica a través del uso del humor, y sobre esto reflexionaba Platón (1992, cuando planteaba que muchas veces ayudaba una broma, en donde la seriedad oponía resistencia. Abstract. This paper studies the importance of humor as a teaching strategy in the classroom, considering the usual lack of motivation and boredom. To analyze whether the “happy teaching and happy learning” may increase effectiveness in the teaching-learning process, the author will discuss how, despite the many benefits it may bring, humor is not used in the classroom due to prejudices and fears. The idea is not for teachers to play the role of a comedian or a clown, but to intervene and get closer to the group with a teaching, didactic purpose through humor. Plato (1992 thought about this; he used to say that sometimes a joke may help, where seriousness put up resistance.

    Full Text Available RESUMO Introdução: O treinamento em circuito é um modelo de treinamento resistido que permite uma variada combinação de sobrecarga e, por isso, requer mais informações para que se compreenda a demanda glicolítica anaeróbia durante sua execução. Objetivo: O objetivo foi comparar dois protocolos de treinamento com pesos, com (Tconv e sem (Tcirc pausa entre as execuções, quanto à resposta do lactato sanguíneo ([la]. Métodos: Onze homens (21,0 ± 2,3 anos; 76,7 ± 5,4 kg, 179,5 ± 7,0 cm foram submetidos ao teste de repetição máxima. O Tcirc e o Tconv foram prescritos a 60%1RM, 12 repetições, sendo três passagens com pausa de 300 s para Tcirc e três séries de cada exercício com 180 s de pausa para o Tconv. Os exercícios que compuseram ambos os protocolos de treinamento foram: supino reto, cadeira extensora unilateral, peck-deck, mesa flexora, pulley alto, leg press 45º, remada horizontal e panturrilha no hack. O teste de ANOVA (Bonferroni post hoc comparou o [la] no 1º, 3º e 5º minuto após as passagens no Tcirc e após cada série no Tconv. O teste t independente comparou as médias do pico de lactato entre Tcirc e Tconv. Em todas as análises adotou-se p ≤ 0,05. Resultados: Foram observadas diferenças para o [la] entre a 1ª (10,6 ± 1,0 mmol/l e a 2ª passagem (13,5 ± 1,8 mmol/l, P = 0,01 e entre a 1ª e a 3ª passagem (15,0 ± 2,5 mmol/l, P < 0,01 no Tcirc. Durante Tconv, os maiores valores médios de [la] foram observadas nos exercícios pulley alto (11,2 ± 2,2 mmol/l e leg press 45º (11,9 ± 2,6 mmol/l. Houve diferença (P < 0,01 ao comparar o pico de [la] após Tconv (12,8 ± 2,2 mmol/l e Tcirc (15,9 ± 2,0 mmol/l. Conclusão: O Tcirc demanda maior resposta glicolítica, enfatizando sua efetividade no aumento da capacidade anaeróbia muscular. Além disso, a execução não intermitente do Tcirc pode explicar sua maior demanda glicolítica, uma vez que Tconv e Tcirc foram proporcionalmente delineados

    Full Text Available O subsolo, normalmente utilizado para produção de mudas de frutíferas, apresenta baixa concentração de zinco e, assim, existe grande probabilidade de resposta à aplicação deste micronutriente. Considerando a falta de informações sobre o assunto, procurou-se avaliar o efeito da aplicação de zinco ao substrato de produção das mudas de goiabeira e acompanhar os efeitos no desenvolvimento, na produção de matéria seca e no estado nutricional das plantas. O delineamento experimental foi em blocos ao acaso, com cinco tratamentos e cinco repetições. As doses de zinco, na forma de sulfato de zinco, foram: 0; 2; 4; 6 e 8 mg dm-3 de Zn. No plantio, as mudas receberam doses de N, P, K e B de 300; 100; 150 e 0,5 mg dm-3, respectivamente. O experimento foi conduzido em viveiro telado, em vasos com 2,8 dm³ de substrato de um Argissolo Vermelho-Amarelo. Após 135 dias do plantio, avaliaram-se: a altura, a área foliar e a matéria seca da parte aérea e das raízes, bem como os teores de macronutrientes e de Zn. As mudas de goiabeira responderam positivamente à aplicação de zinco. O maior desenvolvimento das mudas esteve associado à dose de 2 mg dm-3 de Zn. Doses iguais ou superiores a 4 mg dm-3 causaram redução significativa no desenvolvimento e no acúmulo de macronutrientes nas mudas de goiabeira.

    Material and Methods: Two hundred three medical students (107 males, 96 females were included this study. Self-esteem was measured with the Rosenberg Self Esteem Scale and humor style was measured with Humor Styles Questionnaire. Results: The rate of students who have mild or high self-esteem levels was 89.7%. In Humor Styles Questionnaire, the average scores of affiliative and self-enhancing humor were significantly higher than the average scores of aggressive and self-defeating humor. Male students were using humor, especially aggressive and self-defeating humor styles more commonly than female students. A positive correlation was found between self-esteem and affiliative and self-enhancing humor styles. Conclusion: The present study revealed a positive correlation between self-esteem and positive humor styles. There is a need to develop educational models that would bolster self-esteem and positive humor in medical students. [Cukurova Med J 2015; 40(4.000: 782-793

    To explore lay conceptions of characteristics of an ideal sense of humor as embodied in a known individual, our study examined elicited written narratives by male and female participants from three different countries of origin: United States, Iran, and Turkey. As reported in an earlier previous study with United States-based participants (Crawford and Gressley, 1991), our study also found that the embodiment of an ideal sense of humor was predominantly a male figure. This effect was more pronounced for male than for female participants but did not differ by country. Relative mention of specific humor characteristics differed by participant gender and by country of origin. Whereas all groups mentioned creativity most often as a component of an ideal sense of humor, this attribute was mentioned significantly more often by Americans than by the other two groups; hostility/sarcasm was also mentioned significantly more often by Americans than Turkish participants who mentioned it more often than Iranian participants. Caring was mentioned significantly more often by Americans and Iranians than by Turkish participants. These findings show a shared pattern of humor characteristics by gender but group differences in the relative prominence given to specific humor characteristics. Further work is needed to corroborate the group differences observed and to pinpoint their source.

    Residents frequently use humor and slang at the expense of patients on the clinical wards. We studied how medical students react to and interpret the "appropriateness" of derogatory and cynical humor and slang in a clinical setting. Semistructured, in-depth interviews. Informal meeting spaces. Thirty-three medical students. Qualitative content analysis of interview transcriptions. Students' descriptions of the humorous stories and their responses reveal that students are able to take the perspective of both outsiders and insiders in the medical culture. Students' responses to these stories show that they can identify the outsider's perspective both by seeing themselves in the outsider's role and by identifying with patients. Students can also see the insider's perspective, in that they identify with residents' frustrations and disappointments and therefore try to explain why residents use this kind of humor. Their participation in the humor and slang--often with reservations--further reveals their ability to identify with the perspective of an insider. Medical students describe a number of conflicting reactions to hospital humor that may enhance and exacerbate tensions that are already an inevitable part of training for many students. This phenomenon requires greater attention by medical educators.

  3. Dark Humor in Sula%《秀拉》与黑色幽默

    Dark humor is defined as a stylistic feature with irony at its core. The weapon for the powerless, dark humor always targets those in power. In Sula, Toni Morrison employs irony to satirize African American stereotypes established by racism and sexism. To survive, African Americans ann themselves with humor. Humor implies hope. The (dark) humor in Sula brings spiritual comfort to the victims of racism and sexism, strengthens the Bottom, the black community, challenges the grand narrative of the U.S. history, and proves an essential component of American humor.%黑色幽默是一种文体,反讽是其常用的技巧。黑色幽默是草根的武器,权势是黑色幽默的靶子。在《秀拉》中,莫里森采用反讽,嘲讽种族主义者设定的美国黑人刻板形象,条分缕析地抨击种族歧视和性别歧视。哪里有幽默,哪里就有希望。幽默不但令黑人取得了精神上的胜利,而且挑战美国官方历史的宏大叙事,更为美国幽默增添了多元视角。

    Extent of cerebellar involvement in cognition and emotion is still a topic of ongoing research. In particular, the cerebellar role in humor processing and control of laughter is not well known. A hypermetric dysregulation of affective behavior has been assumed in cerebellar damage. Thus, we aimed at investigating humor comprehension and appreciation as well as the expression of laughter in 21 patients in the acute or subacute state after stroke restricted to the cerebellum, and in the same number of matched healthy control subjects. Patients with acute and subacute cerebellar damage showed preserved comprehension and appreciation of humor using a validated humor test evaluating comprehension, funniness and aversiveness of cartoons ("3WD Humor Test"). Additionally, there was no difference when compared to healthy controls in the number and intensity of facial reactions and laughter while observing jokes, humorous cartoons, or video sketches measured by the Facial Action Coding System. However, as depression scores were significantly increased in patients with cerebellar stroke, a concealing effect of accompanying depression cannot be excluded. Current findings add to descriptions in the literature that cognitive or affective disorders in patients with lesions restricted to the cerebellum, even in the acute state after damage, are frequently mild and might only be present in more sensitive or specific tests.

    As a high-level cognitive activity, humor comprehension requires incongruity detection and incongruity resolution, which then elicits an insight moment. The purpose of the study was to explore the neural basis of humor comprehension, particularly the moment of insight, by using both characters and language-free cartoons in a functional magnetic resonance imaging study. The results showed that insight involving jokes elicited greater activation in language and semantic-related brain regions as well as a variety of additional regions, such as the superior frontal gyrus (SFG), the inferior frontal gyrus (IFG), the middle temporal gyrus (MTG), the superior temporal gyrus (STG), the temporoparietal junctions (TPJ), the hippocampus and visual areas. These findings indicate that the MTG might play a role in incongruity detection, while the SFG, IFG and the TPJ might be involved in incongruity detection. The passive insight event elicited by jokes appears to be mediated by a limited number of brain areas. Our study showed that the brain regions associated with humor comprehension were not affected by the type of stimuli and that humor and insight shared common brain areas. These results indicate that one experiences a feeling of insight during humor comprehension, which contributes to the understanding of humor comprehension.

    To determine aqueous humor CD4+/CD8+ T-lymphocyte ratio changes in sarcoid and non-sarcoid uveitis with anterior chamber involvement. The case-control study includes 61 patients with either anterior uveitis, intermediate uveitis with anterior spill, or panuveitis. A total of 21 of them were categorized as sarcoid uveitis and 40 as non-sarcoid uveitis according to diagnostic criteria. CD4+/CD8+ ratio in the aqueous humor was determined using flow cytometry. Significantly higher CD4+/CD8+ ratio in the aqueous humor was observed in patients with sarcoid uveitis (6.3 ± 1.4; mean ± SEM) compared to non-sarcoid uveitis (1.6 ± 0.1; mean ± SEM). Whole blood CD4+/CD8+ ratio was not elevated in subjects with sarcoid and non-sarcoid uveitis. Aqueous humor CD4+/CD8+ ratio >3.5 was observed to be associated with sarcoid uveitis (OR 38, 95% CI 7.0-205.2). Increased aqueous humor CD4+/CD8+ ratio in sarcoid uveitis. Immunophenotyping of localized lymphocytosis in aqueous humor could be utilized as an additional confirmatory marker for ocular sarcoidosis.

    Plasma opsonic activity as expressed by an alpha-2-globulin which stimulates hepatic Kupffer cell phagocytosis, and thus modulates RES clearance, was determined in patients at varying intervals following whole-body trauma. Plasma opsonic activity decreased markedly following trauma in both nonsurviving (NS) and surviving (S) trauma patients as compared to an age- and sex-matched group of healthy volunteers. The initial post-traumatic hypoopsonemia (0-72 hr) was more severe (p less than 0.01) in nonsurviving patients than surviving patients. Survivors following trauma manifested restoration of opsonin levels with a definite transient rebound hyperopsonemia during the recovery phase (11-30 days); nonsurviving patients exhibited persistent systemic alpha-2-globulin opsonic deficiency. On the basis of previous animal and human studies, the presently observed humoral deficits following trauma in patients could contribute to impairment of reticuloendothelial Kupffer cell clearance of blood-borne particulate matter such as fibrin, damaged platelets, and other altered autologous tissue. The importance of post-trauma RES dysfunction to survival following severe injury warrants further investigation and clinical consideration.

  9. Effects of splenectomy on the humoral immune system

    1978-01-01

    Experiments were performed to investigate the influence of neonatal and adult splenectomy on humoral immunity in mice. In the bone marrow and lymph nodes of both groups of splenectomized mice the number of immunoglobulin (Ig)-positive (B) lymphocytes was significantly higher than in sham-operated mice. These higher numbers of B cells probably reflect a compensation for the absence of the B cell population of the spleen. Hardly any quantitative differences in the serum immunoglobulins were found between splenectomized and sham-splenectomized mice. Only for the IgM class was a significantly lower concentration found in the serum of splenectomized animals. This low concentration of IgM in the blood of splenectomized mice was caused by a failure of the remaining organs to compensate completely for the removal of the quantitatively important population of IgM-producing plasma cells in the spleen. Nevertheless, the number of precursors of IgM-producing plasma cells in bone marrow and lymph nodes and their ability to differentiate into IgM-producing plasma cells was not diminished by splenectomy. Probably the spleen provides a highly efficient environment for the differentiation into IgM-producing plasma cells. By investigating the synergistic ability of bone marrow cells and thymus cells from neonatally splenectomized mice it was found that these cells were fully capable of co-operating in the adoptive plaque-forming cell response to sheep red blood cells (SFBC).

    2008-01-01

    Full Text Available A partir de la afirmación de S. Critchley de que el psicoanálisis es la prolongación, profundización y complicación de lo que él llama paradigma trágico-heroico, se trata de precisar que lo trágico es lo que hace inseparables la teoría y la experiencia psicoanalítica de la risa y los fenómenos ligados a ella. Esto, en general, ha sido insuficientemente indagado. Siguiendo estos argumentos, se presentan algunas observaciones en torno a esa especie de exhortación “volver a las cosas mismas”, tan afín al método freudiano, al “uso” de lo trágico-heroico en Lacan, al concepto de Cosa y al aporte de Freud al humor. Por otra parte, y en completa relación con lo anterior, se destacan algunos señalamientos lacanianos que ubican al “cuerpo” como central en la experiencia de lo cómico. Y por último, se examina la contraposición Bergson - Freud - Lacan en torno a la risa, lo mecánico y el lenguaje.

    Full Text Available Por suas características, modos, técnicas e procedimentos, certos filmes de ficção se enquadram naquilo que chamo de cinema de bordas. O cinema de bordas se faz sobre fragmentos reciclados de gêneros, subgêneros e espécies, sem que, no entanto, nenhum dentre os modelos usados se apresente determinante. Tal reciclagem genérica tem por conseqüência a ausência da novidade e da originalidade, em favor da continuidade e da repetição daquilo já anteriormente conhecido. Nesse sentido, o cinema de bordas comumente recorre a formas que materializam a ação e o sentimento, utilizados tanto por alguns gêneros cinematográficos como pela literatura popular ou literatura de massa. Este trabalho enfoca, em especial, a produção com as formas do horror, do humor e do sexo, quase sempre excluídas do discurso das instituições que consagram uma centralidade canônica. O resultado específico é uma mistura que se alimenta das bordas compostas por diferentes instâncias culturais que vai do estrato mais erudito ao mais popular e vice-versa.

    Full Text Available Abstract. Age dynamics of humoral immunity was studied in healthy children, i.e., 11 newborns, 33 infants of 4 to 8 months, 32 children of 1 to 2 years old,, 17 children of 4 to 5 years old, 25 children of 6 to 8 years old, 15 children of 9 to 11 years old, and 28 adolescents of 14 to 16 years old. Evaluation of membrane receptors on B cells was performed by means of three-colour fluorescent label and allowed of characterizing B1 subpopulations (CD19+CD5+CD27-, naпve B2 cells (CD19+CD5-CD27-, and B2 memory cells (CD19+CD5-CD27+. B1 cells have been shown to dominate in blood of newborns and younger children (up to 5 years old. By the contrary, B2 memory cells were nearly undetectable in newborns, and exceeded 20% in adolescents (by 15 years old. Meanwhile, it has been revealed that the amounts of IgG1 and IgG3 subclasses did progressively increase with age, whereas IgG2 remained decreased to 50% of adult values for a long time, and reached them by 11 years and later. We suggest that the age dynamics of IgG subclasses is connected with age-dependent changes in B cell subpopulations.

RESULTADOS: na análise da amostra pode-se observar ocorrência de simetria <70% nas respostas das emissões otoacústicas em 74,4% do total de neonatos. Por outro lado, na timpanometria, houve uma maior ocorrência de simetria ≥ 70%, tanto para sonda de 226 quanto para 1000Hz (76,9% e 84,6%, respectivamente. No que diz respeito ao gênero e orelha, as diferenças encontradas em cada teste não foram significantes, embora tenha sido observada maior amplitude de respostas de emissões otoacústicas na orelha direita. CONCLUSÃO: os resultados sugerem haver simetria no sistema auditivo em sua porção mais periférica, e início de assimetrias a partir da cóclea.

  15. Emotion and the humors: scoring and classifying major characters from Shakespeare's comedies on the basis of their language.

    Whissell, Cynthia

    2010-06-01

    The theory of humors, which was the prevalent theory of affect in Shakespeare's day, was used to explain both states (moods, emotions) and traits (personalities). This article reports humoral scores appropriate to the major characters of Shakespeare's comedies. The Dictionary of Affect in Language was used to score all words (N = 180,243) spoken by 105 major characters in 13 comedies in terms of their emotional undertones. These were translated into humoral scores. Translation was possible because emotional undertones, humor, and personality (e.g., Eysenck's model) are defined by various axes in the same two-dimensional space. Humoral scores differed for different types of characters, e.g., Shakespeare's lovers used more Sanguine language and his clowns more Melancholy language than other characters. A study of Kate and Petruchio from The Taming of the Shrew demonstrated state-like changes in humor for characters as the play unfolded.

The results of the assay were placed in 5 groups according to the time intervals between injection and collection of serum and aqueous humor (≤70, 75, 80, 90, >90 minutes. Ampicillin activities in sera and aqueous humor of group 5 (>90 minutes were significantly higher than the others (p<0.001. The ratio of ampicillin activities of sera and aqueous humor in group 5 patients was significantly lower indicating higher concentration of ampicillin activity in aqueous humor during this period. Bacterial growth inhibitory activities of ampicillin-sulbactam combination were adequate in aqueous humor of all patients with highest activity being 90 minutes after intramuscular administration indicating the potential usefulness of this antibiotic combination as chemoprophylaxis prior to cataract surgery.

    The present study aimed to determine the protection of blood aqueous barrier by the apraclonidine drops, which is an adrenergic receptor agonist that reduces each of the aqueous humor protein production and the intraocular pressure in glaucomatous rabbits eye before and after treatment with apraclonidine and diode laser trabeculoplasty (DLT).The rabbits were classified into four groups in addition to a normal one. Group (I) was treated with apraclonidine only twice daily, group (II) with apraclonidine before DLT, group (III) with apraclonidine after laser and group (IV) was treated with apraclonidine before and after laser. The aqueous humor was withdrawn from the anterior chamber of the normal and glaucomatous rabbits eye immediately after treatment (direct effect) and one week after treatment for the plasmoid (delayed effect). The intraocular pressure (IOP) was measured then the protein contents and the changes in the molecular structures of aqueous humor proteins were detected using gel column chromatography and electrophoretic mobility. Apraclonidine eye drops led to decrease in IOP and prevented its rise after DLT. The degree of permeability of the barrier was deduced by the amount of protein in the plasmoid aqueous humor after DLT. In normal rabbits, the total protein was increased in the plasmoid aqueous humor. In the four treated groups, the total protein was decreased. The most pronounced decrease was in the group that treated with apraclonidine before and after laser. The change in total protein content was accompanied with change in its molecular weight and electrophoretic mobility. From the obtained results, it could be concluded that the withdrawing of the aqueous humor from the anterior chamber of the eye in appreciable amount leads to reformation of new aqueous humor (plasmoid) with elevated protein concentration. Moreover, the treatment with apraclonidine before DLT completely protected the blood aqueous barrier from disruption caused by laser and

    Focusing on sex, the most salient topic featured in ageist jokes, this study aims at exploring the extent to which seniors' own humor reflects common ageist stereotypes or rather echoes contemporary consumer society representations of seniors' sexuality. The study was based on a quantitative content analysis of 300 humorous sex-related messages posted during one full year by members of 14 leading online communities for seniors. Findings indicated that whereas the portrayal of older adults in humor typically relied on negative ageist stereotypes, their representation in seniors' online sex-related humor depended on the social identity of the butt of this humor. If it was an in-group member (oneself, another community member, or the community as a whole), the portrayal was rather positive, but when the butt belonged to the out-group (older adults in general), the depiction was far more ageist. Nonetheless, the representation of older butts of humor was generally more positive than that of the younger ones. These findings suggest that seniors tend to identify with current cultural representations of sexuality in later life and use sex-related humor as a personal means of resisting ageism. They apply two principal strategies: Distancing-reproducing certain ageist stereotypes by ascribing them to other older adults, but less so to their own group and even less than that to themselves-and equalizing older and younger individuals, even according the former an advantage regarding sexuality. © The Author 2017.

    Trace elements might play a role in the complex multifactorial pathogenesis of open-angle glaucoma. The aim of this study was to analyze concentrations of trace elements in aqueous humor samples of patients with primary open-angle glaucoma (POAG) and pseudoexfoliation glaucoma (PEXG). Thirty-three aqueous humor samples were obtained from patients undergoing cataract surgery: 12 patients with POAG (age 65.3±10.50, female 8, male 4), 10 patients with PEXG (age 65.9±11.27, female 6, male 4) and 11 patients without glaucoma (age 69.5±13.70, female 7, male 4) serving as controls. Aqueous humor levels of cadmium, iron, manganese, cobalt, copper and zinc were measured by Flow-Injection-Inductively-Coupled-Plasma-Mass-Spectrometry (FI-ICP-MS). From the statistical evaluation, we observed that patients with POAG had significantly higher aqueous humor levels of zinc (p=0.006) compared to controls. Increased aqueous humor levels of zinc were also observed in patients with PEXG in relation to control (p=0.0006). For iron we observed a significantly reduction in PEXG compared to control (p=0.002) and a significant difference between POAG and PEXG (p=0.0091). No significant differences were observed in aqueous humor levels of manganese, cobalt, copper, cadmium between glaucoma and control patients. No differences were seen for iron (POAG vs. controls). Analysis of trace element ratios was added. Significant differences in aqueous humor levels of zinc and iron between glaucoma and control patients support the hypothesis that these trace elements are involved in the pathogenesis of open-angle glaucoma.

    Full Text Available Anti-Toxocara antibody production and persistence were studied in experimental infections of BALB/c mice, according to three different schedules: Group I (GI - 25 mice infected with 200 T. canis eggs in a single dose; Group II (GII 25 mice infected with 150 T. canis eggs given in three occasions, 50 in the 1st, 50 in the 5th and 50 in the 8th days; Group III (GIII - 25 mice also infected with 150 T. canis eggs, in three 50 eggs portions given in the 1st, 14th and 28th days. A 15 mice control group (GIV was maintained without infection. In the 30th, 50th, 60th, 75th, 105th and 180th post-infection days three mice of the GI, GII and GIII groups and two mice of the control group had been sacrificed and exsanguinated for sera obtention. In the 360th day the remainder mice of the four groups were, in the same way, killed and processed. The obtained sera were searched for the presence of anti-Toxocara antibodies by an ELISA technique, using T. canis larvae excretion-secretion antigen. In the GI and GII, but not in the GIII, anti-Toxocara antibodies had been found, at least, up to the 180th post-infection day. The GIII only showed anti-Toxocara antibodies, at significant level, in the 30th post-infection day.Estudou-se a cinética de anticorpos anti-Toxocara em camundongos BALB/c infectados experimentalmente segundo três esquemas: Grupo I (GI: 25 camundongos infectados com dose única de 200 ovos embrionados de T. canis; grupo II (GII: 25 camundongos infectados com 150 ovos embrionados de T. canis, divididos em três doses de 50 ovos, administrados no 1º, 5º e 8º dias; Grupo III (GIII: 25 camundongos infectados com 150 ovos embrionados de T. canis, administrados em três doses de 50 ovos no 1º, 14º e 28º dias. Um grupo de 15 camundongos foi mantido nas mesmas condições, porém sem infecção, constituindo o grupo controle (GIV. No 30º, 50º, 60º, 75º, 105º e 180º dias pós-infecção três camundongos dos grupos GI, GII e GIII e dois do grupo controle foram sacrificados sob anestesia e sangrados para obtenção de soro. No 360º dia os animais restantes dos quatro grupos foram igualmente sacrificados. Pesquisou-se a presença de anticorpos anti-Toxocara nos soros obtidos utilizando-se teste imunoenzimático (ELISA e empregando-se antígeno de excreção-secreção produzido por larvas de T. canis mantidas em cultura. Nos grupos GI e GII revelou-se a presença de anticorpos anti-Toxocara, em níveis elevados, pelo menos até o 180º dia após infecção. Nos camundongos do grupo GIII apenas no 30º dia pós-infecção foi possível detectar anticorpos anti-Toxocara.

    Full Text Available Dengue viruses (DENV are the most important mosquito transmitted viral pathogens infecting humans. DENV infection produces a spectrum of disease, most commonly causing a self-limiting flu-like illness known as dengue fever; yet with increased frequency, manifesting as life-threatening dengue hemorrhagic fever (DHF. Waning cross-protective immunity from any of the four dengue serotypes may enhance subsequent infection with another heterologous serotype to increase the probability of DHF. Decades of effort to develop dengue vaccines are reaching the finishing line with multiple candidates in clinical trials. Nevertheless, concerns remain that imbalanced immunity, due to the prolonged prime-boost schedules currently used in clinical trials, could leave some vaccinees temporarily unprotected or with increased susceptibility to enhanced disease. Here we develop a DENV serotype 1 (DENV-1 DNA vaccine with the immunodominant cross-reactive B cell epitopes associated with immune enhancement removed. We compare wild-type (WT with this cross-reactivity reduced (CRR vaccine and demonstrate that both vaccines are equally protective against lethal homologous DENV-1 challenge. Under conditions mimicking natural exposure prior to acquiring protective immunity, WT vaccinated mice enhanced a normally sub-lethal heterologous DENV-2 infection resulting in DHF-like disease and 95% mortality in AG129 mice. However, CRR vaccinated mice exhibited redirected serotype-specific and protective immunity, and significantly reduced morbidity and mortality not differing from naïve mice. Thus, we demonstrate in an in vivo DENV disease model, that non-protective vaccine-induced immunity can prime vaccinees for enhanced DHF-like disease and that CRR DNA immunization significantly reduces this potential vaccine safety concern. The sculpting of immune memory by the modified vaccine and resulting redirection of humoral immunity provide insight into DENV vaccine induced immune

    Previous research and theory implicate that personality traits, such as extraversion and neuroticism, influence the processing of humor, as indicated by alterations in the activation of fronto-temporal and mesocorticolimbic brain regions during humor processing. In the current study, we sought to complement these findings by testing whether inter-individual differences in functional connectivity of humor-related brain regions are modulated by stable personality characteristics during humor processing. Using fMRI techniques, we studied 19 healthy subjects during the processing of standardized humorous and neutral cartoons. In order to isolate the specific effects of humor appreciation, subjective funniness ratings, collected during the scanning procedure, were implemented in the analysis as parametric modulation. Two distinct clusters in the right amygdala and the left insula were identified. Seed-to-voxel connectivity analysis investigating the effects of personality on inter-individual differences in functional connectivity revealed that amygdala and insula connectivity with brain areas previously related to humor comprehension (e.g. middle temporal gyrus) and appreciation (e.g. caudate nucleus) were significantly modulated by personality dimensions. These results underscore the sensitivity of humor processing to moderating influences, such as personality, and call attention to the importance of brain connectivity measures for the investigation of inter-individual differences in the processing of humor.

  15. No Occasion for Pleasure: The Self-Worth Contingency of a Setback and Coping With Humor

    Directory of Open Access Journals (Sweden)

    Full Text Available Whether or not one uses humor to cope with a setback may depend on the idiosyncratic relation of the setback to feeling of self-worth. All people pursue the higher order goal of self-validation, but people differ in what domains of life their self-worth is contingent upon and to what extent. In this article based on an incongruity theory of humor we argue that the use of humor in coping with a highly self-worth-contingent setback may be impeded by two cognitive-motivational processes: goal-driven activation and goal shielding. From the outlined theory we derived the hypothesis that the more a domain is contingent upon self-worth, the less likely a person will be to use humor to deal with a setback in that domain. We tested this hypothesis in two studies employing two forms of self-report, i.e., ratings of reaction likelihood to setbacks described at an abstract domain level (Study 1, and ranking of reaction likelihood to concrete setbacks from different domains (Study 2. The hypothesis was affirmed in different domains of self-worth contingency controlling for the influence of habitual coping with humor, coping by disengagement, and global self-esteem.

    Infancy is a critical time for the development of secure attachment, which is facilitated by emotionally synchronous interactions with parents. Humor development, which includes shared laughter and joint attention to an event, emerges concurrently with attachment, but little is known regarding the relationship, if any, between humor development and attachment in the first year. Thirty 3-month-old infants were videoed at home each month until they were 6-months old while their parents attempted to amuse them. Frequency of infants’ smiles and laughs served as a measure of “state humor”, and the smiling/laughing subscale of the Infant Behavior Questionnaire-Revised served as a measure of “trait humor”. State and trait humor were not correlated. Lower trait humor as 6 months predicted higher attachment security on the Attachment Q-sort at 12-months (r=. 46), suggesting that less good-humored infants elicit greater parental engagement, which works to the benefit of attachment, or vice versa. Future studies should examine the importance of smiling and laughter as they relate to other developmental phenomena in the first year. PMID:22982281

    Full Text Available With a diversity of promotional channels and ever-increasing numbers of participants, the tourism industry in Taiwan faces keen competition. Along with the direct cross-strait flights policy, groups like Eastern Multimedia Group, Tsann Kuen Enterprise Company Limited and Want Want China Times Group have founded travel agencies for the purpose of increasing their market share in the tourism industry. Therefore, the formulation of marketing strategies has become a critical issue for all travel agencies that wish to ensure their prominence in the market. The frequent use of humorous materials and appeals has been the main tendency in advertising. However, no consistent conclusions regarding the actual effects of humorous advertising have been determined. The subjects of the current study were users of the Lion Travel website. Online questionnaires were sent to and collected from random respondents. One hundred questionnaires were delivered, and 512 valid questionnaires were collected. Each collected questionnaire represented a valid sample. The study generated the following five results: (1 humorous advertisements may partially influence brand awareness; (2 humorous elements may partially influence advertising effects; (3 brand awareness has significant positive effects on the advertising attitude of advertising effects; (4 brand awareness has significant positive effects on the brand attitude of advertising effects; (5 brand awareness has significant positive effects on the purchasing intention of advertising effects. Eventually, it is anticipated that the results of this study can serve as a reference and provide suggestions for humorous advertising strategies in the tourism industry.

    Purpose In humans, vitrectomy is associated with development of nuclear cataracts. Iron catalyzes free radical formation causing oxidative damage, which is implicated in cataract formation. This study was designed to determine if vitreous humor, which can initiate differentiation of lens epithelial cells, would have an effect on iron-handling proteins. Methods Cultured canine lens epithelial cells were treated with collected canine vitreous humor. Lysates of treated and control cells were separated by SDS-PAGE. Ferritin H- and L-chains, transferrin receptor 1, and aquaporin 0 were immunodetected and quantitated with specific antibodies. Morphologic changes in treated cells were assessed. Results Treatment of lens epithelial cells with a 33% (vol/vol) solution of vitreous humor changed the morphology of lens cells and induced expression of aquaporin 0, a marker of fiber cell differentiation that was undetectable in control cells. Treatment did not modify the size of iron-handling proteins but significantly increased content of ferritin from 2.9- to 8.8-fold over control and decreased levels of transferrin receptor by 37% to 59%. Conclusions Vitreous humor may significantly limit iron uptake by transferrin/transferrin receptor pathway, and by increasing ferritin levels could profoundly increase the iron-storage capacity of ferritin in lens cells. Vitreous humor may play a significant protective role against iron-catalyzed oxidative damage of lens epithelial cells and therefore in the formation of cataracts. PMID:28245299

    Estimation of postmortem interval (PMI) plays a crucial role in forensic study and identification work. Because of the unique anatomy location, vitreous humor is considered to be used for estima- ting PMI, which has aroused interest among scholars, and some researches have been carried out. The detection techniques of vitreous humor are constantly developed and improved which have been gradually applied in forensic science, meanwhile, the study of PMI estimation using vitreous humor is updated rapidly. This paper reviews various techniques and instruments applied to vitreous humor detection, such as ion selective electrode, capillary ion analysis, spectroscopy, chromatography, nano-sensing technology, automatic biochemical analyser, flow cytometer, etc., as well as the related research progress on PMI estimation in recent years. In order to provide a research direction for scholars and promote a more accurate and efficient application in PMI estimation by vitreous humor analysis, some inner problems are also analysed in this paper.

    Numerous behavioral studies and a handful of functional neuroimaging studies have reported sex differences in humor. However, no study to date has examined differences in the time-course of brain activity during multistage humor processing between the sexes. The purpose of this study was to compare real-time dynamics related to humor processing between women and men, with reference to a proposed three-stage model (involving incongruity detection, incongruity resolution, and elaboration stages). Forty undergraduate students (20 women) underwent event-related potential recording while subjectively rating 30 question-answer-type jokes and 30 question-answer-type statements in a random order. Sex differences were revealed by analyses of the mean amplitudes of difference waves during a specific time window between 1000 and 1300 ms poststimulus onset (P1000-1300). This indicates that women recruited more mental resources to integrate cognitive and emotional components at this late stage. In contrast, men recruited more automated processes during the transition from the cognitive operations of the incongruity resolution stage to the emotional response of the humor elaboration stage. Our results suggest that sex differences in humor processing lie in differences in the integration of cognitive and emotional components, which are closely linked and interact reciprocally, particularly in women.
