    Emerging evidence from fMRI studies suggests that humor processing is a specific social cognitive-affective human function that comprises two stages. The first stage (cognitive humor component) involves the detection and resolution of incongruity, and is associated with activity in temporo-occipito-parietal brain areas. The second stage (emotional humor component) comprises positive feelings related to mirth/reward, and is linked with reward-related activity in mesocorticolimbic circuits. In healthy adults, humor processing was shown to be moderated by temperament traits like intro-/extraversion, neuroticism, or social anxiety, representing risk factors for psychopathology. However, comparable data from early developmental stages is crucially lacking. Here, we report for the first time data from 22 children (ages 6 to 13) revealing an influence of temperament on humor processing. Specifically, we assessed the effects of Emotionality, Shyness, and Sociability, which are analogous to neuroticism, behavioral inhibition/fear and extraversion in adults. We found Emotionality to be positively, but Shyness negatively associated with brain activity linked with both cognitive and emotional humor components. In addition, Shyness and Sociability were positively related to activity in the periaqueductal gray region during humor processing. These findings are of potential clinical relevance regarding the early detection of childhood psychopathology. Previous data on humor processing in both adults and children furthermore suggest that intelligence (IQ) supports incongruity detection and resolution, whereas mirth and associated brain activity diminishes with increasing age. Here, we found that increasing age and IQ were linked with stronger activity to humor in brain areas implicated in the cognitive component of humor. Such data suggest that humor processing undergoes developmental changes and is moderated by higher IQ scores, both factors likely improving incongruity detection

    To investigate the role of endothelial nitric oxide synthase (eNOS) on conventional outflow function using NOS3 knockout (KO) mice. Intraocular pressure was measured in both NOS3 KO and wild type (WT) by rebound tonometry. Outflow facility was measured by perfusing enucleated mouse eyes at multiple pressure steps. A subset of eyes was sectioned and stained for histology. Mock aqueous humor ± the nitric oxide (NO) donors nitroprusside dihydrate (SNP) or S-Nitroso-N-Acetyl-D,L-Penicillamine (SNAP) was perfused into enucleated eyes. SNP and SNAP was administered topically at 0, 1, 2, and 3 hours while the contralateral eyes served as vehicle controls. Intraocular pressure was measured in both eyes before and after the last drug treatment. Intraocular pressure was higher in KO mice (18.2 ± 0.7 mm Hg vs. 13.9 ± 0.5 mm Hg, mean ± SEM, n = 30, P NOS3 KO mice have elevated IOP, which is likely the result of reduced pressure-dependent drainage. These findings are consistent with human data showing polymorphisms in the NOS3 gene associate with ocular hypertension and the development of glaucoma.

    Full Text Available B regulatory cells (Bregs are shown to downregulate autoimmune and inflammation processes. Their modifying effects depend on IL-10 secretion. A role of Bregs in development of humoral immune response was not investigated. Influence of Bregs and IL-10 upon in vitro response of murine B1 and B2 cells to T-dependent and T-independent antigens was studied in a model system. A water-soluble sheep erythrocyte antigen was used as a T-dependent antigen, whereas LPS was applied as a type 1 T-independent antigen, and polyvinylpirrolidone and alpha(1→3dextran were added as type 2 T-independent antigens. В1and B2 lymphocytes were isolated from, respectively, peritoneal cavity and spleen of CBA mice. The cells were cultured in RPMI1640 medium with 10% of FCS supplemented with appropriate antigens and IL-10. The numbers of antibody- and total Ig-forming cells were determined by ELISPOT method.The erythrocyte antigen induced an increase of antibody- and total Ig-forming cell numbers in cultured B1 and B2 cell populations. IL-10 addition caused reduction of antibody- and total Ig-forming cells by 27%. Similarly, IL-10 caused a drop in antibody- and total Ig-forming cells in LPS-stimulated B2 cell cultures by 75%, as well as 50 per cent decrease in numbers of antibody-forming cells in B-1 cell cultures when induced by the type 2 T-independent antigens.To assess functional activity of Bregs, the cells were isolated from peritoneal cavity and spleen of CBA mice. Total yields of Bregs were 20-fold increased upon activation of B cells with LPS, ionomycin and phorbol ester (from 4% to 96%. IgM was the main immunoglobulin isotype secreted by the Bregs. 96% of activated Bregs produced IL-10. About 12% of the cells were shown to produce immunoglobulins. This finding suggests that some of Bregs synthesize both IL-10 and immunoglobulins.To study distant effect of Bregs upon immune response, the splenocyte culture of xid CBA/N mice were tested in Transwells with

    2011-01-01

    This study investigates the differences in physiological, cognitive, and emotional responses to existing emotional antialcohol abuse advertisements (fear vs. humor appeal) between high and low sensation seekers. A 2 (Message Type) x 2 (Sensation-Seeking Tendency) x 4 (Message Repetition) mixed-model experiment with repeated measures was conducted with 71 college students. The results, based on self-reports, indicated that fear messages generated more interest and perceived danger of excessive drinking regardless of sensation-seeking tendency, whereas humorous messages were rated as more likeable than fear messages, and the difference was bigger among low sensation seekers than among high sensation seekers. One interesting finding was that for both fear and humor appeals, low sensation seekers showed greater emotional responses (greater corrugators activities and greater zygomatic activities) than high sensation seekers overall. The implications of the current study as well as suggestions for future study were discussed.

    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.

    Full Text Available Trabecular meshwork (TM bypass surgeries attempt to enhance aqueous humor outflow (AHO to lower intraocular pressure (IOP. While TM bypass results are promising, inconsistent success is seen. One hypothesis for this variability rests upon segmental (non-360 degrees uniform AHO. We describe aqueous angiography as a real-time and physiologic AHO imaging technique in model eyes as a way to simulate live AHO imaging.Pig (n = 46 and human (n = 6 enucleated eyes were obtained, orientated based upon inferior oblique insertion, and pre-perfused with balanced salt solution via a Lewicky AC maintainer through a 1mm side-port. Fluorescein (2.5% was introduced intracamerally at 10 or 30 mm Hg. With an angiographer, infrared and fluorescent (486 nm images were acquired. Image processing allowed for collection of pixel information based on intensity or location for statistical analyses. Concurrent OCT was performed, and fixable fluorescent dextrans were introduced into the eye for histological analysis of angiographically active areas.Aqueous angiography yielded high quality images with segmental patterns (p<0.0001; Kruskal-Wallis test. No single quadrant was consistently identified as the primary quadrant of angiographic signal (p = 0.06-0.86; Kruskal-Wallis test. Regions of high proximal signal did not necessarily correlate with regions of high distal signal. Angiographically positive but not negative areas demonstrated intrascleral lumens on OCT images. Aqueous angiography with fluorescent dextrans led to their trapping in AHO pathways.Aqueous angiography is a real-time and physiologic AHO imaging technique in model eyes.

  12. Self-esteem instability and humor styles: does the stability of self-esteem influence how people use humor?

    2014-01-01

    The purpose of the present study was to examine whether self-esteem instability moderated the association between self-esteem level and the use of humor. This was accomplished by examining the associations that humor styles had with self-esteem level and self-esteem instability among 499 undergraduates. The results of the present study show that self-esteem instability moderated the association between self-esteem level and humor styles such that individuals with stable high self-esteem reported the highest levels of affiliative humor as well as the lowest levels of aggressive and self-defeating humor. These results suggest that individuals with stable and unstable forms of self-esteem employ different styles of humor.

    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.

  14. Physiological factors influencing capillary growth.

    (1) Angiogenesis (growth of new capillaries from an existing capillary bed) may result from a mismatch in microvascular supply and metabolic demand (metabolic error signal). Krogh examined the distribution and number of capillaries to explore the correlation between O(2) delivery and O(2) consumption. Subsequently, the heterogeneity in angiogenic response within a muscle has been shown to reflect either differences in fibre type composition or mechanical load. However, local control leads to targetted angiogenesis in the vicinity of glycolytic fibre types following muscle stimulation, or oxidative fibres following endurance training, while heterogeneity of capillary spacing is maintained during ontogenetic growth. (2) Despite limited microscopy resolution and lack of specific markers, Krogh's interest in the structure of the capillary wall paved the way for understanding the mechanisms of capillary growth. Angiogenesis may be influenced by the response of perivascular or stromal cells (fibroblasts, macrophages and pericytes) to altered activity, likely acting as a source for chemical signals modulating capillary growth such as vascular endothelial growth factor. In addition, haemodynamic factors such as shear stress and muscle stretch play a significant role in adaptive remodelling of the microcirculation. (3) Most indices of capillarity are highly dependent on fibre size, resulting in possible bias because of scaling. To examine the consequences of capillary distribution, it is therefore helpful to quantify the area of tissue supplied by individual capillaries. This allows the spatial limitations inherent in most models of tissue oxygenation to be overcome generating an alternative approach to Krogh's tissue cylinder, the capillary domain, to improve descriptions of intracellular oxygen diffusion. © 2010 The Author.

    1980-02-01

    We studied aqueous humor of rhesus and owl monkeys for its effect on the growth of subconjunctival fibroblasts in tissue culture. Aqueous humor samples obtained before glaucoma surgery inhibited the initiation of growth of fibroblasts. However, postoperative aqueous humor samples supported growth of fibroblasts. The change in aqueous humor physiology lasted for up to two months after glaucoma surgery. Our study indicated that possibly material added to the postoperative aqueous humor inactivates an inhibitor normally present in primary aqueous humor. An alternative explanation would be that primary aqueous humor, in contrast to secondary aqueous humor, lacks sufficient nutrient material to support fibroblast growth in tissue culture.

    This study was designed to answer the question: Does the contact of the human organism with the Earth via a copper conductor affect physiologic processes? Subjects and experiments: Five (5) experiments are presented: experiment 1-effect of earthing on calcium-phosphate homeostasis and serum concentrations of iron (N = 84 participants); experiment 2-effect of earthing on serum concentrations of electrolytes (N = 28); experiment 3-effect of earthing on thyroid function (N = 12); experiment 4-effect of earthing on glucose concentration (N = 12); experiment 5-effect of earthing on immune response to vaccine (N = 32). Subjects were divided into two groups. One (1) group of people was earthed, while the second group remained without contact with the Earth. Blood and urine samples were examined. Earthing of an electrically insulated human organism during night rest causes lowering of serum concentrations of iron, ionized calcium, inorganic phosphorus, and reduction of renal excretion of calcium and phosphorus. Earthing during night rest decreases free tri-iodothyronine and increases free thyroxine and thyroid-stimulating hormone. The continuous earthing of the human body decreases blood glucose in patients with diabetes. Earthing decreases sodium, potassium, magnesium, iron, total protein, and albumin concentrations while the levels of transferrin, ferritin, and globulins α1, α2, β, and γ increase. These results are statistically significant. Earthing the human body influences human physiologic processes. This influence is observed during night relaxation and during physical activity. Effect of the earthing on calcium-phosphate homeostasis is the opposite of that which occurs in states of weightlessness. It also increases the activity of catabolic processes. It may be the primary factor regulating endocrine and nervous systems.

  2. Humor's healing potential.

    In the past three decades the medical world has begun to take more serious notice of the healing power of humor and the positive emotions associated with it. Humor and laughter are currently being employed by psychotherapists and other care givers as tools to promote and maintain health, as well as intervention and rehabilitation tools for a host of maladies and illnesses related to stress and life-style. Although this empirical medical approach is relatively new, the study of humor has revealed a complex psychological phenomenon. Senses of humor have been categorized in types associated with personality. Humor has many styles and can be found in almost any situation, on any occasion. Theories of humor include the superiority theory, the incongruity theory, the release/relief theory, and the divinity theory. Laughter has many clinical benefits, promoting beneficial physiological changes and an overall sense of well-being. Humor even has long-term effects that strengthen the effectiveness of the immune system. In healthcare, humor therapy can help relieve stress associated with disease and illness. It serves as a diversionary tactic, a therapeutic tool for disorders such as depression, and a coping mechanism. It also is a natural healing component for care givers trying to cope with the stress and personal demands of their occupations.

  3. Aqueous Humor Dynamics: A Review

    Goel, Manik; Picciani, Renata G; Lee, Richard K; Bhattacharya, Sanjoy K

    2010-01-01

    Glaucoma is a family of optic neuropathies which cause irreversible but potentially preventable vision loss. Vision loss in most forms of glaucoma is related to elevated IOP with subsequent injury to the optic nerve. Secretion of aqueous humor and regulation of its outflow are physiologically important processes for maintaining IOP in the normal range. Thus, understanding the complex mechanisms that regulate aqueous humor circulation is essential for management of glaucoma. The two main structures related to aqueous humor dynamics are the ciliary body and the trabecular meshwork (TM). Three mechanisms are involved in aqueous humor formation: diffusion, ultrafiltration and active secretion. Active secretion is the major contributor to aqueous humor formation. The aqueous humor flow in humans follows a circadian rhythm, being higher in the morning than at night. The aqueous humor leaves the eye by passive flow via two pathways - the trabecular meshwork and the uveoscleral pathway. In humans, 75% of the resistance to aqueous humor outflow is localized within the TM with the juxtacanalicular portion of the TM being the main site of outflow resistance. Glycosaminoglycan deposition in the TM extracellular matrix (ECM) has been suggested to be responsible for increased outflow resistance at this specific site whereas others have suggested deposition of proteins, such as cochlin, obstruct the aqueous humor outflow through the TM. The uveoscleral outflow pathway is relatively independent of the intraocular pressure and the proportion of aqueous humor exiting the eye via the uveoscleral pathway decreases with age.

    To test the hypothesis that individual and institutional-level factors influence the effects of a humor therapy intervention on aged care residents. Data were from the humor therapy group of the Sydney Multisite Intervention of LaughterBosses and ElderClowns, or SMILE, study, a single-blind cluster randomized controlled trial of humor therapy conducted over 12 weeks; assessments were performed at baseline, week 13, and week 26. One hundred eighty-nine individuals from 17 Sydney residential aged care facilities were randomly allocated to the humor therapy intervention. Professional performers called "ElderClowns" provided 9-12 weekly humor therapy 2-hour sessions, augmented by trained staff, called "LaughterBosses." Outcome measures were as follows: Cornell Scale for Depression in Dementia, Cohen-Mansfield Agitation Inventory, Neuropsychiatric Inventory, the withdrawal subscale of Multidimensional Observation Scale for Elderly Subjects, and proxy-rated quality of life in dementia population scale. Facility-level measures were as follows: support of the management for the intervention, commitment levels of LaughterBosses, Environmental Audit Tool scores, and facility level of care provided (high/low). Resident-level measures were engagement, functional ability, disease severity, and time-in-care. Multilevel path analyses simultaneously modeled resident engagement at the individual level (repeated measures) and the effects of management support and staff commitment to humor therapy at the cluster level. Models indicated flow-on effects, whereby management support had positive effects on LaughterBoss commitment, and LaughterBoss commitment increased resident engagement. Higher resident engagement was associated with reduced depression, agitation, and neuropsychiatric scores. Effectiveness of psychosocial programs in residential aged care can be enhanced by management support, staff commitment, and active resident engagement. Copyright © 2014 American Association for

  8. MHC Class II and Non-MHC Class II Genes Differentially Influence Humoral Immunity to Bacillus anthracis Lethal Factor and Protective Antigen

    2012-12-01

    Full Text Available Anthrax Lethal Toxin consists of Protective Antigen (PA and Lethal Factor (LF, and current vaccination strategies focus on eliciting antibodies to PA. In human vaccination, the response to PA can vary greatly, and the response is often directed toward non-neutralizing epitopes. Variable vaccine responses have been shown to be due in part to genetic differences in individuals, with both MHC class II and other genes playing roles. Here, we investigated the relative contribution of MHC class II versus non-MHC class II genes in the humoral response to PA and LF immunization using three immunized strains of inbred mice: A/J (H-2k at the MHC class II locus, B6 (H-2b, and B6.H2k (H-2k. IgG antibody titers to LF were controlled primarily by the MHC class II locus, whereas IgG titers to PA were strongly influenced by the non-MHC class II genetic background. Conversely, the humoral fine specificity of reactivity to LF appeared to be controlled primarily through non-MHC class II genes, while the specificity of reactivity to PA was more dependent on MHC class II. Common epitopes, reactive in all strains, occurred in both LF and PA responses. These results demonstrate that MHC class II differentially influences humoral immune responses to LF and PA.

  9. Beyond conformity: Social influences on pain reports and physiology.

    2016-02-01

    Social information can profoundly influence behavior, but its effects are often explained in terms of "conformity," implying effects on decision-making and communication rather than deeper sensory modulation. We examined whether information about other people's pain reports affected both participants' pain experience and skin conductance responses (SCR) during pain. Sixty volunteers experienced painful heat stimulation preceded by 2 kinds of informational cues: (a) nonreinforced social information indicating low or high pain ratings from previous participants; and (b) reinforced conditioned stimuli (CSlow, CShigh). Both high-pain social information and CShigh cues enhanced pain and SCRs relative to their respective controls, with particularly robust effects of social information. Effects of both manipulations on both pain and SCRs were mediated by trial-by-trial pain expectancies. These results demonstrate strong social influences on pain and autonomic responses, and suggest that expectations from multiple sources can influence pain physiology independent of reinforcement.

    The effects of food restriction or 20 ppm NO/sub 2/ exposure on humoral immunity were investigated in normal and adrenalectomized C/sub 57/B1/6 mice. The thymic and splenic weights of sham-operated mice were similarly diminished after 4 days of NO/sub 2/ exposure or 4 days of food depletion. The responses of corresponding adrenalectomized mice were less depressed. Undernutrition induced lymphoid organ involution and corticosteroids were partly involved. Plaque-forming cells (PFC) per spleen and per 10/sup 6/ cells were markedly depressed after 4 days of NO/sub 2/ exposure, but less so after food deprivation. The same significant suppression of PFC was observed in adrenalectomized groups. Depression of humoral immunity was independent of stress-induced endogenous steroids. Moreover, NO/sub 2/ had a specific effect on humoral immunodepression, food restriction being an associated factor.

    Exposure to environmental stressors alters animal phenotypes as well as nutrient metabolism, assimilation, and excretion. While stress-induced shifts in nutrient processes are known to alter organismal carbon (C) and nitrogen (N) stoichiometry, there has been little exploration of how environmental factors influence phosphorous (P). A better understanding of how P cycling varies with animal physiological state may provide insight into across-scale processes, because P is essential to animal function and ecological processes such as production and decomposition. We tested the effects of predator stress and exogenous glucocorticoids on C∶N∶P stoichiometry of larval amphibians. Glucocorticoids altered nutrient stoichiometry, apparently by modulating ossification and renal function. This reduced whole-body P and significantly increased N∶P. Additionally, elevated glucocorticoids caused a long-term reduction in P excretion. This reduction may reflect an initial unmeasured loss of P that glucocorticoids induce over acute timescales. In contrast, exposure to predator cues had no effect on larval C∶N∶P stoichiometry, which highlights that different stressors have varied effects on the endocrine stress response. Predation, in particular, is ubiquitous in the environment; thus, larvae responding to predators have conserved mechanisms that likely prevent or minimize physiological disruption. These results demonstrate the differing physiological roles of N and P, distinct nutrient demands associated with amphibian metamorphosis, and the contrasting effects that different environmental factors have on the physiological stress response. Our results also suggest that anthropogenic changes to the environment that induce chronic stress in amphibians could affect the biogeochemistry of nutrient-poor environments where they may act as keystone species.

    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.

    Full Text Available Introduction. Systemic lupus erythematosus (SLE — severe autoimmune disease that has a high level of morbidity and mortality. With each decade the SLE incidence rate grows up. Current researches do not allow to identify the etiology of this disease. The polyclonal stimulation of T and B lymphocytes processes are prevailed in pathogenetic picture of the disease. One of the most powerful triggers of stimulation may be a gram-negative bacteria lipopolysaccharide (LPS or endotoxin (ET. The impact activity is regulated by a specific humoral and cellular antiendotoxin immune response.Materials and methods. The study group involved 48 patients with SLE, the control group consisted of 40 healthy donors. The material of the study was the venous blood. The following indicators have been identified: the levels of specific anti-endotoxin antibodies (antiLPS IgA, IgM and IgG, by enzyme linked immunosorbent assay (ELISA; concentration of total immunoglobulins IgA, IgM and IgG — microturbidimethric method; the concentration of C-reactive protein (CRP — ELISA; endogenous intoxication (EI — a method of determining the average molecular weight for the absorption in the ultraviolet spectrum; circulating immune complexes (CIC — the method of precipitation in polyethylene glycol. Statistical processing was performed using Microsoft Office Excel 2007 software and MedStat®.Results. The study showed a statistically significant increase in anti-LPSIgG SLE patients by 2.5 times compared with the control group. A slight increase in total IgG by 5%. Endogenous intoxication index in SLE patients was higher by 13.9%, CIC by 150%. The level of CRP in the study group was 6.8 times higher compared with the control. There were also identified the inverse correlation between anti-LPS-IgG and CRP, the inverse correlation between anti-LPS-IgG and EI, direct correlation between anti-LPS-IgA and the age of patients.Discussion.

    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.

    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.

    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.

    Laughter and humor therapy have been used in health care to achieve physiological and psychological health-related benefits. The application of these therapies to the dialysis context remains unclear. This paper reviews the evidence related to laughter and humor therapy as a medical therapy relevant to the dialysis patient population. Studies from other groups such as children, the elderly, and persons with mental health, cancer, and other chronic conditions are included to inform potential applications of laughter therapy to the dialysis population. Therapeutic interventions could range from humorous videos, stories, laughter clowns through to raucous simulated laughter and Laughter Yoga. The effect of laughter and humor on depression, anxiety, pain, immunity, fatigue, sleep quality, respiratory function and blood glucose may have applications to the dialysis context and require further research.

    The authors examined whether different levels of sense of humor would influence respondents' ratings about a potentially desirable partner. The authors used vignettes to predict that the targets who possessed a good sense of humor would receive significantly higher ratings in measures of attractiveness and suitability as a long-term partner than would those who possessed an average or no sense of humor. In an experimental design--with gender and humor as independent variables and level of attractiveness and suitability as a long-term partner as dependent variables--the authors analyzed the data using a multivariate analysis of variance. Results show that the targets with a good sense of humor received significantly higher ratings of attractiveness and suitability than did those with an average or no sense of humor. Furthermore, male participants rated female targets as significantly more attractive than female participants rated male targets. The authors found no significant interaction between gender and humor.

    2016-01-01

    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.

    2012-01-01

    Wildlife translocation is increasingly used to mitigate disturbances to animals or habitat due to human activities, yet little is known about the extent to which translocating animals causes stress. To understand the relationship between physiological stress and translocation, we conducted a multiyear study (2007–2009) using a population of desert tortoises (Gopherus agassizii) near Fort Irwin, California. Blood samples were collected from adult tortoises in three treatment groups (resident, translocated and control) for 1 year prior to and 2 years after translocation. Samples were analyzed by radioimmunoassay for plasma total corticosterone (CORT), a glucocorticoid hormone commonly associated with stress responses in reptiles. CORT values were analyzed in relation to potential covariates (animal sex, date, behavior, treatment, handling time, air temperature, home-range size, precipitation and annual plant production) among seasons and years. CORT values in males were higher than in females, and values for both varied monthly throughout the activity season and among years. Year and sex were strong predictors of CORT, and translocation explained little in terms of CORT. Based on these results, we conclude that translocation does not elicit a physiological stress response in desert tortoises.

    In the last decade antioxidants from a group of polyphenols have been proposed as one of the most effective functional ingredients of anti-ageing properties that counteract the effects of oxidative damage to the skin. It has been shown that the use of polyphenols affects skin protection and mitigates inflammatory conditions of the skin. Numerous studies have confirmed that polyphenols by neutralizing free radicals, antioxidant activity and by their ability to chelate ions of transition metals can effectively reduce the level of nonprotein inflammatory mediators. The biological activity of polyphenols in the skin is primarily determined by their physicochemical properties and the ability to overcome the epidermal barrier as they try to reach appropriate receptors. This study reviews literature on the effects of polyphenols relating to the physiological processes in the skin and role of the major plant polyphenols in cosmetology and dermatology.

    We investigated whether exposure to same humorous antitobacco videos via different types of social media platforms and contexts (health vs. humor) influences individual's health risk perceptions, attitudes, and behavioral intents. An experiment with a 2 (social media types: YouTube and Facebook) × 2 (message contexts: health-focused and humor-focused contexts) factorial design was conducted. It was found that those who watched the humorous antitobacco videos on Facebook in the health-context exhibited a higher level of risk perception of smoking, less positive attitude toward smokers, and a higher level of intention to avoid smoking in the future than the participants who viewed the same videos on YouTube in the health-context or on Facebook in the humor-context. These findings provide useful practical guidelines in using social media for health communication/promotion. Humorous health promotion messages are best circulated on social networking sites such as Facebook accompanied by others' support for the given health topic (i.e., in health-contexts). Practical/theoretical implications and limitations of the study were further discussed in this article.

    Humor is spread throughout every culture on earth and occupies a large portion of our literature and social interaction. It is so deeply rooted in our culture that it may be a defining characteristic of our species. Yet there has been comparatively little effort to understand its origin. According to the Accepted Theory of Humor all jokes begin with a buildup of tension while an initial paradigm is formed. When the punch line occurs the subject must realign his thinking to accommodate the differences between the initial paradigm and the sudden burst of new information. The Mind Reading Hypothesis extends the accepted theory of humor to include a relationship between the observer and the subject of the humor. The actual source of amusement is the observation of the resolution in the mind of the subject of the collision between old perception and new reality.

  7. Humor and sexual selection.

    Science.gov (United States)

    Storey, Robert

    2003-12-01

    Recently Geoffrey Miller has suggested that humor evolved through sexual selection as a signal of "creativity," which in turn implies youthfulness, intelligence, and adaptive unpredictability. Drawing upon available empirical studies, I argue that the evidence for a link between humor and creativity is weak and ambiguous. I also find only tenuous support for Miller's assumption that the attractiveness of the "sense of humor" is to be found in the wittiness of its possessor, since those who use the phrase often seem to associate it with the affects of relatively mirthless "bonding" laughter. Humor, I conclude, may have evolved as an instrument for achieving broad social adhesiveness and for facilitating the individual's maneuverability within the group, but that it evolved through sexual selection has yet to be convincingly demonstrated.

    2016-01-01

    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.

    Between-partner physiological linkage can be in-phase (changes in unison), or anti-phase (changes in opposite directions). In the context of conversation we predicted that in-phase linkage would occur when partners exert strong influence on each other; anti-phase linkage would occur due to the behavioral coordination of turn taking. To test this, blood pressure, inter-beat interval, and skin conductance were recorded from 44 heterosexual couples while they discussed how they influence each other's health-related behaviors. Partner influence was assessed in two ways: 1) partners' global perceptions of how they try to influence each other's health; and 2) behavioral manifestations of influence, specifically demand-withdraw behavior. As predicted, both measures of partner influence moderated physiological linkage of blood pressure such that at low levels of influence linkage was "anti-phase" and at high levels linkage was "in-phase." Several alternative hypotheses were ruled out; the effects were not due to relationship conflict, emotional experience, or simply the pattern of blood pressure over time. These results suggest that partner influence may be driving physiological linkage, which may be one avenue through which partners can affect each other's health.

    This study attempted to determine whether humor production moderates mood and physiological responses to stress of subjects high and low in trait humor. Forty subjects who were high and 40 subjects who were low in trait humor were selected. Half of each group was randomly assigned to one of two conditions. In one condition they generated a humorous monologue and in the other condition they generated a serious monologue to a silent stressful film. Heart rate, skin conductance level, and skin temperature were taken continuously for the fifteen minutes before, during, and fifteen minutes after the film. Pre- and post-stress mood and tension ratings were also recorded. Analyses of covariance were conducted with baseline mood and tension as covariates. Compared to the production of a serious narrative, humor production led to lower negative affect, lower tension, and reduced psychophysiological reactivity for both high and low trait-humor groups. These results suggest that humor production may be an effective coping strategy, even for individuals who do not typically use humor to cope with stress.

    Understanding immune function is critical to conserving wildlife in view of infectious disease threats, particularly in threatened species vulnerable to stress, immunocompromise and infection. However, few studies examine stress, immune function and infection in wildlife. We used a flow cytometry protocol developed for human infants to assess phagocytosis, a key component of innate immunity, in a critically endangered marsupial, the woylie (Bettongia penicillata). The effects of stress physiology and Trypanosoma infection on phagocytosis were investigated. Blood and faecal samples were collected from woylies in a captive facility over three months. Trypanosoma status was determined using PCR. Faecal cortisol metabolites (FCM) were quantified by enzyme-immunoassay. Mean phagocytosis measured was >90%. An interaction between sex and FCM influenced the percentage of phagocytosing leukocytes, possibly reflecting the influence of sex hormones and glucocorticoids. An interaction between Trypanosoma status and FCM influenced phagocytosis index, suggesting that stress physiology and infection status influence innate immunity.

    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.

    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.

    2012-01-01

    Full Text Available Objective. To determine whether genetic variants suggested by the literature to be associated with physiology and fitness phenotypes predicted differential physiological and subjective responses to a bout of aerobic exercise among inactive but otherwise healthy adults. Method. Participants completed a 30-minute submaximal aerobic exercise session. Measures of physiological and subjective responding were taken before, during, and after exercise. 14 single nucleotide polymorphisms (SNPs that have been previously associated with various exercise phenotypes were tested for associations with physiological and subjective response to exercise phenotypes. Results. We found that two SNPs in the FTO gene (rs8044769 and rs3751812 were related to positive affect change during exercise. Two SNPs in the CREB1 gene (rs2253206 and 2360969 were related to change in temperature during exercise and with maximal oxygen capacity (VO2 max. The SLIT2 SNP rs1379659 and the FAM5C SNP rs1935881 were associated with norepinephrine change during exercise. Finally, the OPRM1 SNP rs1799971 was related to changes in norepinephrine, lactate, and rate of perceived exertion (RPE during exercise. Conclusion. Genetic factors influence both physiological and subjective responses to exercise. A better understanding of genetic factors underlying physiological and subjective responses to aerobic exercise has implications for development and potential tailoring of exercise interventions.

  6. Physiological stress response to loss of social influence and threats to masculinity.

    Science.gov (United States)

    Taylor, Catherine J

    2014-02-01

    Social influence is an important component of contemporary conceptualizations of masculinity in the U.S. Men who fail to achieve masculinity by maintaining social influence in the presence of other men may be at risk of stigmatization. As such, men should be especially likely to exhibit a stress response to loss of social influence in the presence of other men. This study assesses whether men who lose social influence exhibit more of a stress response than men who gain social influence, using data collected in a laboratory setting where participants were randomly assigned into four-person groups of varying sex compositions. The groups were videotaped working on two problem-solving tasks. Independent raters assessed change in social influence using a well-validated measure borrowed from experimental work in the Status Characteristics Theory tradition. Cortisol is used as a measure of stress response because it is known to increase in response to loss of social esteem. Results show that young men who lose social influence while working with other young men exhibit cortisol response. In contrast women do not exhibit cortisol response to loss of social influence, nor do men working with women. Results are consistent with the hypothesis that loss of social influence in men may be associated with a physiological stress response because maintaining social influence is very important to men while in the presence of other men. This physiological response to loss of social influence underscores the importance to men of achieving masculinity through gaining and maintaining social influence, and avoiding the stigma associated with the failure to do so.

    Full Text Available Effects of humor in advertisement published in Colombia were investigated in regards to brands,advertisement, purchase intention, recall and recognition.A simultaneous Classical Conditioning procedure was carried out, using Incongruous, Hostile and Allusivehumor associated to three brands. The procedure was applied to 30 university students. Results revealedthat the three kinds of humor work as unconditioning stimulus, generating positive attitudes towardsadvertisement and brand. Humor influences the purchase intention and recognition, but not the remembranceof brand when compared to neutral advertisement. Incongrous and Hostile Humor generate recognitionand positive attitude towards advertisement and brand. Allusions have a greater effect on purchaseintention than the other ones. Results corroborate the effectiveness of humor as an advertisement tool.

    2016-01-01

    Objective Here we investigate ganglion cell physiology in healthy and degenerating retina to test its influence on threshold to electrical stimulation. Approach Age-related Macular Degeneration and Retinitis Pigmentosa cause blindness via outer retinal degeneration. Inner retinal pathways that transmit visual information to the central brain remain intact, so direct electrical stimulation from prosthetic devices offers the possibility for visual restoration. Since inner retinal physiology changes during degeneration, we characterize physiological properties and responses to electrical stimulation in retinal ganglion cells of both wild type mice and the rd10 mouse model of retinal degeneration. Main results Our aggregate results support previous observations that elevated thresholds characterize diseased retinas. However, a physiology-driven classification scheme reveals distinct sub-populations of ganglion cells with thresholds either normal or strongly elevated compared to wild-type. When these populations are combined, only a weakly elevated threshold with large variance is observed. The cells with normal threshold are more depolarized at rest and exhibit periodic oscillations. Significance During degeneration, physiological changes in retinal ganglion cells affect the threshold stimulation currents required to evoke action potentials. PMID:26905177

  12. Perception of aggressive humor in relation to gelotophobia, gelotophilia, and katagelasticism

    Full Text Available The present study investigates humor appreciation of aggressive cartoons in relation to gelotophobia, gelotophilia, and katagelasticism. These traits were described to have a peculiar relation to laughter-related phenomena, in particular to disparagement humor. 185 participants rated highly aggressive and non-aggressive humorous stimuli for funniness and aversiveness and their scores on the gelotophobia, gelotophilia and katagelasticism scales were measured. The cartoons were controlled for their structural basis, i.e., incongruity-resolution and nonsense humor, as these two types of humor strongly influence the appreciation of humorous stimuli. The results revealed that high scores on gelotophobia lead to higher aversion to aggressive humor, whereas high scores on katagelasticism lead to more enjoyment of aggressive humor with less aversion. Gelotophobia and katagelasticism lead to sensitivity to aggression in humor, which fits the overt behavior of reacting sensitively towards laughter (gelotophobia and enjoying to laugh at others (katagelasticism. Gelotophilia did not predict reactions to either aggressive or non-aggressive humor but did predict more amusement in general: High scorers on gelotophilia seem to be relaxed towards any form of humor, even if it has an aggressive note. This study confirms the three dimensions to have peculiar responses to aggressive types of humor and opens up several questions to be explored in future research.

    Full Text Available The purpose of this research work is to investigate the influence of phase-change materials (PCMs on thermo-physiological comfort of different male business clothing systems evaluated in warm environment. The impact of particular business clothing on the thermo-physiological comfort of the wearer during different physical activity and environmental conditions (between 25°C and 10°C with step of 5°C, artificially created in a climate chamber, was determined experimentally, as a change of three physiological parameters of a human being: mean skin temperature, heart rate, and the amount of evaporated and condensed sweat. A questionnaire and an assessment scale were also used before, during, and after each experiment in order to evaluate the wearer’s subjective feeling of comfort. The results of the performed research work show that male business clothing systems in combination with PCMs do not affect the thermal-physiological comfort of the wearer in warm environment significantly, except at an ambient temperature of 15°C, where clothing systems in combination with PCMs produce a small heating effect. Furthermore, it was concluded that clothing systems in combination with PCMs indicate a small temporary thermal effect that is reflected in a slight rising or lowering of mean skin temperature during activity changes.

  14. Physiological, psychological, social, and cultural influences on the use of menthol cigarettes among Blacks and Hispanics.

    Science.gov (United States)

    Castro, Felipe González

    2004-02-01

    Patterns of menthol cigarette consumption among Blacks and Hispanics are likely a product of the interactive effects of several factors: the physiological and pharmacological sensory effects of menthol, the "cool" psychological identity of being menthol smokers, the promotional marketing of menthol cigarettes, and the cultural effects of health-related beliefs and subjective culture norms. This article presents two conceptual frameworks--a moderation logic model and a mediation logic model--for organizing the disparate literature on factors affecting the consumption of menthol cigarettes among Blacks and Hispanics. Three factor domains are examined as direct effect predictors of menthol cigarette smoking: (a) physiological and pharmacological, (b) psychological, and (c) social and environmental. In addition, a fourth domain of cultural variables is presented as a class of moderator or mediator variables that can interact with these physiological, psychological, and social factors as determinants of menthol cigarette use. These cultural variables are examined as mediating or moderating factors that influence the use of menthol cigarettes by Black and Hispanic consumers. Recommendations are offered for future research to further understand the influence of cultural and other factors as determinants of menthol cigarette smoking among Blacks and Hispanics.

    The present study had two goals: first, to give a detailed description of a reliable method for full kinetic analysis of serotonin transporter (5HTt) on the membrane of human platelets, and second, as a main issue, to report on physiological influences on kinetic characteristics of this transmembrane transport on a large population of healthy individuals. Full kinetic analyses of platelet serotonin uptake were performed on 334 blood donors of both sexes by the use of 14C-radioisotopic method, which was first optimized according to assumptions of enzyme kinetic analyses, with regard to platelet concentration, duration of uptake, concentration of substrate as well as important technical parameters (underpressure of filtration, blanks, incubating temperature, etc). Kinetic parameters of platelet serotonin uptake in the whole population were for V(max): 142 +/- 25.3 pmol 5HT/10(8) platelets/minute and for K(m): 0.404 +/- 0.089 microM 5HT. Besides the report on kinetic values of 5HT transporter protein, we have also described major physiological influences on the mentioned parameters, V(max), K(m) and their derivative, V(max)/K(m) (transporter efficiency): range and frequency distribution of normal values, intraindividual stability over time, lack of age influence, gender dependence and seasonal variations. The report on kinetic values and main physiological influences on platelet serotonin transport kinetics, obtained by the use of thoroughly reassessed methodology, and on by far the largest human population studied until now, offers a reliable frame of reference for pathophysiological studies of this parameter in various clinical fields.

    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

    This study examined the relationship between humor styles and loneliness among a sample of Hong Kong and Mainland Chinese. A total of 159 Hong Kong undergraduates and 178 Hangzhou undergraduates were recruited to complete a survey composed of the Humor Styles Questionnaire and the Emotional and Social Loneliness Scales. Multiple regression analyses showed that self-defeating humor explained significant variance in both social and emotional loneliness for Hong Kong students, but only in social loneliness for Hangzhou students. Hong Kong students scored significantly higher on aggressive humor and self-defeating humor, and scored significantly lower on affiliative humor and self-enhancing humor than did their counterparts in Hangzhou. This could be attributed to the greater influence of Confucianism in Mainland China than in Hong Kong.

  5. On Untranslatability of Humor in Mark Twain's Novels and Compensating Strategy

    Mark Twain was a well-known 19th-century American author and a reputed critical realist. His novels are excellent for combining humor with irony, which reveal his criticism of kinds of miserable reality in American society. His humor is not just for humorous effect, but has serious and profound social connotations. So when readers of the target language are reading his novels, their understanding of the deep purpose and connotations would be influenced by the quality of translation of those humors. Therefore, translators must own language competence and sufficient knowledge about the cultural background, for humor is a typical example of untranslatability. This paper makes an analysis of the two types of untranslatability: the cultural untranslatability and the linguistic and takes translation of humor in Mark Twain's novels as examples to analyze the untranslatability of humor in literature and gives suggestions of compensating strategy.

    Aqueous humor flows out of the eye primarily through the conventional outflow pathway that includes the trabecular meshwork and Schlemm's canal. However, a fraction of aqueous humor passes through an alternative or 'unconventional' route that includes the ciliary muscle, supraciliary and suprachoroidal spaces. From there, unconventional outflow may drain through two pathways: a uveoscleral pathway where aqueous drains across the sclera to be resorbed by orbital vessels, and a uveovortex pathway where aqueous humor enters the choroid to drain through the vortex veins. We review the anatomy, physiology and pharmacology of these pathways. We also discuss methods to determine unconventional outflow rate, including direct techniques that use radioactive or fluorescent tracers recovered from tissues in the unconventional pathway and indirect methods that estimate unconventional outflow based on total outflow over a range of pressures. Indirect methods are subject to a number of assumptions and generally give poor agreement with tracer measurements. We review the variety of animal models that have been used to study conventional and unconventional outflow. The mouse appears to be a promising model because it captures several aspects of conventional and unconventional outflow dynamics common to humans, although questions remain regarding the magnitude of unconventional outflow in mice. Finally, we review future directions. There is a clear need to develop improved methods for measuring unconventional outflow in both animals and humans. Copyright © 2016 Elsevier Ltd.

    Williams, Michele; Emich, Kyle J

    2014-01-01

    The purpose of this study was to investigate failed interpersonal affect regulation through the lens of humor. We investigated individual differences that influenced people's affective and cognitive responses to failed humor and their willingness to persist in the interpersonal regulation of positive affect after a failed attempt. Using well-established autobiographical narrative methods and surveys, we collected data at two time points. All participants (n = 127) received identical surveys at time 1. At time 2, they were randomly assigned to complete a narrative about either successful or failed humor as well as a second survey. Using moderated regression analyses and SEM, we found significant differences between our failed and successful humor conditions. Specifically, individual differences, including gender, affective perspective taking, and humor self-efficacy, were associated with negative reactions to failed humor and the willingness of individuals to persist in the interpersonal regulation of positive affect. Moreover, affective perspective taking moderated the effect of gender in both the failed and successful humor conditions. Our results suggest that failed humor is no laughing matter. Understanding individuals' willingness to continue in attempts to regulate the affect of others contributes to the comprehension of an understudied phenomenon that has implications for interpersonal behavior in organizations such as helping, group decision making, and intragroup conflict. Studies of interpersonal affect regulation often focus on people's ability to successfully regulate others' emotions. In contrast, this is the first quantitative study to explore factors that influence individual's willingness to persist in interpersonal affect regulation after failure, and to investigate how individual differences influence the personal outcomes associated with failed attempts.

    The influences of different rootstocks on chilling tolerance and physiological parameters in wa-termelon seedlings have been studied. The results showed that grafting improved the chilling tolerance. Com-pared with own-rooted watermelon seedlings, the grafted watermelon seedlings had lower chilling injury index,lower electrolytic leakage (%), lower malondialdehyde (MDA) content, higher chlorophyll and proline con-tent, and higher activities of superoxide dismutase (SOD), ascorbate peroxidase (AsA-POD) and de-hydroascorbate reductase (DR) in the leaves under iow temperature stress. There was a considerable differenceof chilling tolerance among different grafted watermelon seedlings due to the difference of rootstock chillingtolerance. After low temperature treatment, the grafted seedling with higher chilling tolerance had lower elec-trolytic leakage ( %), lower MDA content, higher proline content and higher activities of SOD, AsA-POD andDR in the leaves compared with the grafted seedling with weaker chilling tolerance. From these, we could con-clude that chilling tolerance of watermelon seedlings may be related to higher antioxidative ability and mem-brane stability in the plants. The chilling tolerance of grafted seedling could be properly evaluated by compre-hensive physiological indexes but not a single physiological index.

    Through potted inoculation test at room temperature and indoor analysis, the photosynthetic parameters and physiological and biochemical indexes of Paris polyphylla var. yunnanensis were observed after 28 arbuscular mycorrhizal (AM) fungi were injected into the P. polyphylla var. yunnanensis growing in a sterile soil environment. The results showed that AM fungi established a good symbiosis with P. polyphylla var. yunnanensis. The AM fungi influenced the photosynthetic parameters and physiological and biochemical indexes of P. polyphylla var. yunnanensis. And the influences were varied depending on different AM fungi. The application of AM fungi improved photosynthesis intensity of P. polyphylla var. yunnanensis mesophyll cells, the contents of soluble protein and soluble sugar, protective enzyme activity of P. polyphylla var. yunnanensis leaf, which was beneficial to resist the adverse environment and promote the growth of P. polyphylla var. yunnanensis. Otherwise, there was a certain mutual selectivity between P. polyphylla var. yunnanensis and AM fungi. From the comprehensive effect of inoculation, Racocetra coralloidea, Scutellospora calospora, Claroideoglomus claroideum, S. pellucida and Rhizophagus clarus were the most suitable AM fungi to P. polyphylla var. yunnanensis when P. polyphylla var. yunnanensis was planted in the field.

  19. Experimentally Manipulating Items Informs on the (Limited) Construct and Criterion Validity of the Humor Styles Questionnaire.

    Ruch, Willibald; Heintz, Sonja

    2017-01-01

    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. The present findings thus call for a reevaluation of the role that humor plays in the HSQ (construct validity) and in the relationships to personality and well-being (criterion validity).

  20. Physiological state influences the social interactions of two honeybee nest mates.

    Full Text Available Physiological state profoundly influences the expression of the behaviour of individuals and can affect social interactions between animals. How physiological state influences food sharing and social behaviour in social insects is poorly understood. Here, we examined the social interactions and food sharing behaviour of honeybees with the aim of developing the honeybee as a model for understanding how an individual's state influences its social interactions. The state of individual honeybees was manipulated by either starving donor bees or feeding them sucrose or low doses of ethanol to examine how a change in hunger or inebriation state affected the social behaviours exhibited by two closely-related nestmates. Using a lab-based assay for measuring individual motor behaviour and social behaviour, we found that behaviours such as antennation, willingness to engage in trophallaxis, and mandible opening were affected by both hunger and ethanol intoxication. Inebriated bees were more likely to exhibit mandible opening, which may represent a form of aggression, than bees fed sucrose alone. However, intoxicated bees were as willing to engage in trophallaxis as the sucrose-fed bees. The effects of ethanol on social behaviors were dose-dependent, with higher doses of ethanol producing larger effects on behaviour. Hungry donor bees, on the other hand, were more likely to engage in begging for food and less likely to antennate and to display mandible opening. We also found that when nestmates received food from donors previously fed ethanol, they began to display evidence of inebriation, indicating that ethanol can be retained in the crop for several hours and that it can be transferred between honeybee nestmates during trophallaxis.

    The aim of this study was to investigate somatic properties and physiological capacity, and analyze kinematic parameters in the 200 m breaststroke swimming race. Twenty-seven male swimmers participated in the study. They were 15.7±1.98 years old. Their average height was 1.80 ± 0.02 m and lean body mass (LBM) was 62.45 ± 8.29 kg. Physiological exercise capacity was measured in two separate 90 sec. all-out tests, one for the arms and second for legs. During the tests total work of arm cranking (TWAR) and cycling (TWLG) as well as peak of VO2 for arm (VO2peakAR) and leg (VO2peakLG) were measured. The underwater swimmers body movements were recorded during the all-out swimming 200m breaststroke speed test using an underwater camera installed on a portable trolley. The swimming kinematic parameters and propulsive or non-propulsive movement phases of the arms and legs as well as average speed (V200), surface speed (V200surface) and swimming speed in turn zones (V200turns) were extracted. V200surface was significantly related to the percentage of leg propulsion and was shown to have large effect on VO2peakLG in the Cohen analysis. V200turns depended significantly on the indicators of physiological performance and body structure: TWAR, VO2peak LG and LBM, LBM, which in turn strongly determined the measured results of TWAR, TWLG, VO2peakAR and VO2peakLG. The V200turns and V200surface were strongly associated with V200, 0.92, p cycles. Key pointsThis study investigated the influence of the selected indicators of somatic properties and physiological capacity as well kinematic and coordination parameters on breaststroke swimming.In this observations the body's functional capacity have an important impact on achieving good breaststroke swimming results, the V200 was moderately associated on VO2peakLG, moreover, separate V200turns depended with VO2peakLG and on LBM and TWAR.The speed of surface breaststroke swimming - V200surface similarly as V200turns had a very strong

It is about how the extra linguistics elements dominate the situation and the delivery of humor. The researchers of the present paper intend to show how the selected literary extract can be subjected to a linguistic pragmatic analysis and then be explained by applying the incongruity theory of humor by Kant (1790 in order to show the ways or the mechanisms that lead to the flouting, infringing and the violation of Gricean maxims can consequently lead to the creation of humor.

  3. The influence of physical and physiological cues on atomic force microscopy-based cell stiffness assessment.

    Directory of Open Access Journals (Sweden)

    Yu-Wei Chiou

    Full Text Available Atomic force microscopy provides a novel technique for differentiating the mechanical properties of various cell types. Cell elasticity is abundantly used to represent the structural strength of cells in different conditions. In this study, we are interested in whether physical or physiological cues affect cell elasticity in Atomic force microscopy (AFM-based assessments. The physical cues include the geometry of the AFM tips, the indenting force and the operating temperature of the AFM. All of these cues show a significant influence on the cell elasticity assessment. Sharp AFM tips create a two-fold increase in the value of the effective Young's modulus (E(eff relative to that of the blunt tips. Higher indenting force at the same loading rate generates higher estimated cell elasticity. Increasing the operation temperature of the AFM leads to decreases in the cell stiffness because the structure of actin filaments becomes disorganized. The physiological cues include the presence of fetal bovine serum or extracellular matrix-coated surfaces, the culture passage number, and the culture density. Both fetal bovine serum and the extracellular matrix are critical for cells to maintain the integrity of actin filaments and consequently exhibit higher elasticity. Unlike primary cells, mouse kidney progenitor cells can be passaged and maintain their morphology and elasticity for a very long period without a senescence phenotype. Finally, cell elasticity increases with increasing culture density only in MDCK epithelial cells. In summary, for researchers who use AFM to assess cell elasticity, our results provide basic and significant information about the suitable selection of physical and physiological cues.

    Studies were conducted to determine the effect of vermicompost on growth, physiological disorders, fruit yield and quality of 'Chandler' strawberry. For this, 4 levels of vermicompost (2.5, 5.0, 7.5 and 10.0tha(-1)) were supplemented with inorganic fertilizers to balance fertilizer requirement of strawberry under semi-arid region of northern India. The vermicompost was incorporated into top 10cm layer of soil, which was supplemented on the basis of chemical analysis, with amount of inorganic N, P, K fertilizer calculated to equalize the recommended dose of nutrients. Vermicompost application increased plant spread (10.7%), leaf area (23.1%) and dry matter (20.7%), and increased total fruit yield (32.7%). Substitution of vermicompost drastically reduced the incidence of physiological disorders like albinism (16.1-4.5%); fruit malformation (11.5-4.0%) and occurrence of grey mould (10.4-2.1%) in strawberry indicating that vermicompost had significant role in reducing nutrient-related disorders and disease like Botrytis rot, and thereby increasing the marketable fruit yield up to 58.6% with better quality parameters. Fruit harvested from plant receiving vermicompost were firmer, have higher TSS, ascorbic acid content and lower acidity, and have attractive colour. All these parameters appeared to be dose dependent and best results were achieved @ 7.5tha(-1), however, beyond this dose of vermicompost, there was not significant influence on these parameters.

    Ustilago maydis, a dimorphic fungus causing corn smut disease, serves as an excellent model to study different aspects of cell development. This study shows the influence of chitosan, oligochitosan and glycol chitosan on cell growth and physiology of U. maydis. These biological macromolecules affected the cell growth of U. maydis. In particular, it was found that chitosan completely inhibited U. maydis growth at 1mg/mL concentration. Microscopic studies revealed swellings on the surface of the cells treated with the polymers, and chitosan caused complete destruction of the membrane and formation of vesicles on the periphery of the cell. Oligochitosan and chitosan caused changes in oxygen consumption, K(+) efflux and H(+)-ATPase activity. Oligochitosan induced a faster consumption of oxygen in the cells, while glycol chitosan provoked slower oxygen consumption. It is noteworthy that chitosan completely inhibited the fungal respiratory activity. The strongest effects were exhibited by chitosan in all evaluated aspects. These findings showed high sensitivity of U. maydis to chitosan and provided evidence for antifungal effects of chitosan derivatives. To our knowledge, this is a first report showing that chitosan and its derivatives affect the cell morphology and physiological processes in U. maydis.

    The monitoring of {sup 137}Cs contamination of fish from the northern part of the Kiev reservoir between 1987 and 1992 indicated systematic differences in the long-term average contamination levels of different species, which are closely related to their trophic levels. The average contamination of the predatory species: perch (Perca fluviatilis) and pike (Esox lucius) were roughly factors of 6.3 and 4.4 respectively, higher than those of the nonpredatory species: bream (Abramis brama), silver bream (Blicca bjoerkna) and rudd (Scardinius erythrophothalmus). For tench (Tinca tinca) and goldfish (Carassius sp.), this factor is 2. The solution of the caesium balance equation in fish obtained for equilibrium conditions, which is applicable to the long-term contamination, provides some explanations for these accumulation differences between the species with respect to influences by different ecological and physiological factors.

    2001-02-01

    A series of studies have shown that humor is associated with close interpersonal relationships and effective in reducing stress, which in turn enhances empathy. Therefore, it was hypothesized that humor and empathic concern would be positively correlated. The Empathic Concern subscale of the Empathy Questionnaire, the Coping Humor Scale, the Multidimensional Sense of Humor Scale, and the Situational Humor Response Questionnaire were given to 124 subjects. Scores on the Empathic Concern subscale were significantly correlated with those on each of the humor scales. Types of humor may be an important variable in the relationship between empathic concern and humor. Both humor and empathic concern are associated for people with emotional intelligence who use these to interact effectively with other individuals. As such, it was suggested that exploration would yield a relation between humor and emotional self-awareness, which is also associated with emotional intelligence.

    Cerium oxide nanoparticles (CeO2 NPs) are commonly used as polishing agents for industry and fuel additives to decrease the particulate matter emissions. CeO2 NPs may be encountered in the soil and water environment through their life cycle or accidental releases, and have potential phytotoxicity effects. Therefore, it is critical to assess the potential effects of CeO2 NPs in soil on plant growth and physiology. The objective of this research is to determine the physiological responses of three sorghums (Grassl, BtX623 and Rio) to the effect of CeO2 nanoparticles in potting soil environment. Sorghums were germinated and grown in potting soil in the greenhouse for three weeks cultivation with treatments of 0, 100, 500, 1000 mg CeO2 NPs per kg soil. Plant parameters, such as length, weight, and biomass of root and leaves were measured in each treatment with 12 replications. After three weeks germination, the sorghum plants were dig out and the roots were examined and scanned by the Silverfast SE Plus scanner to compare and analyze their dimensions and shapes. To further study the growth and physiological changes in plants due to the presence of CeO2 NPs in soil, one selected type of sorghum (Grassl) was grown under the four different CeO2 NPs concentration treatments for six months until plant maturity, and was also cut and harvested three times to study CeO2 NPs effect on plant re-growth. At the end of each growing period, above ground vegetative tissues were air-dried, grounded to 2mm particle size and compositional traits were estimated by using near-infrared spectroscopy. The influence of nanoparticles was observed on some of the plant traits. Preliminary results showed the influence of CeO2 NPs on the roots growth, as Grassl and Btx623 in 100 mgkg-1 treatment grew significantly faster than other concentrations; however no significant difference between control and 100 mgkg-1 treatment in Rio. CeO2 NPs concentration of 100 mgkg-1 had no impact on sorghum growth

    A previous study showed that the use of nitrate by Dekkera bruxellensis might be an advantageous trait when ammonium is limited in sugarcane substrate for ethanol fermentation. The aim of the present work was to evaluate the influence of nitrate on the yeast physiology during cell growth in different carbon sources under oxygen limitation. If nitrate was the sole source of nitrogen, D. bruxellensis cells presented slower growth, diminished sugar consumption and growth-associated ethanol production, when compared to ammonium. These results were corroborated by the increased expression of genes involved in the pentose phosphate (PP) pathway, the tricarboxylic acid (TCA) cycle and ATP synthesis. The presence of ammonium in the mixed medium restored most parameters to the standard conditions. This work may open up a line of investigation to establish the connection between nitrate assimilation and energetic metabolism in D. bruxellensis and their influence on its fermentative capacity in oxygen-limited or oxygen-depleted conditions.

    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.

    Humor can be found everywhere in our daily life. It shows one's wisdom and confidence, which reflects a person's character, mind and cultivation. While it makes people laugh, it enlightens and instruct people. As we all know, English humor is a manifestation of the western literature. However, people in non-English speaking countries cannot completely understand English humor because of the differences of different cultures. The present paper starts from the analysis of English humor, trying to find out some ways of achieving humor so as to better our understanding and appreciation of English humor.

    Patch time allocation has received much attention in the context of optimal foraging theory, including the effect of environmental variables. We investigated the direct role of temperature on patch time allocation by parasitoids through physiological and behavioural mechanisms and its indirect role via changes in sex allocation and behavioural defences of the hosts. We compared the influence of foraging temperature on patch residence time between an egg parasitoid, Trichogramma euproctidis, and an aphid parasitoid, Aphidius ervi. The latter attacks hosts that are able to actively defend themselves, and may thus indirectly influence patch time allocation of the parasitoid. Patch residence time decreased with an increase in temperature in both species. The increased activity levels with warming, as evidenced by the increase in walking speed, partially explained these variations, but other mechanisms were involved. In T. euproctidis, the ability to externally discriminate parasitised hosts decreased at low temperature, resulting in a longer patch residence time. Changes in sex allocation with temperature did not explain changes in patch time allocation in this species. For A. ervi, we observed that aphids frequently escaped at intermediate temperature and defended themselves aggressively at high temperature, but displayed few defence mechanisms at low temperature. These defensive behaviours resulted in a decreased patch residence time for the parasitoid and partly explained the fact that A. ervi remained for a shorter time at the intermediate and high temperatures than at the lowest temperature. Our results suggest that global warming may affect host-parasitoid interactions through complex mechanisms including both direct and indirect effects on parasitoid patch time allocation.

    Sky view factor (SVF), which is an indicator of urban canyon geometry, affects the surface energy balance, local air circulation, and outdoor thermal comfort. This study focused on a continuous and long-term meteorological observation system to investigate the effects of SVF on outdoor thermal conditions and physiological equivalent temperature (PET) in the central business district (CBD) of Beijing (which is located within Chaoyang District), specifically addressed current knowledge gaps for SVF-PET relationships in cities with typical continental/microthermal climates. An urban sub-domain scale model and the RayMan model were used to diagnose wind fields and to calculate SVF and long-term PET, respectively. Analytical results show that the extent of shading contributes to variations in thermal perception distribution. Highly shaded areas (SVF 0.5), and vice versa. Because Beijing has a monsoon-influenced humid continental climate with hot summers and long, cold, windy, and dry winters, a design project that ideally provides moderate shading should be planned to balance hot discomfort in summer and cold discomfort in winter, which effectively prolongs the comfort periods in outdoor spaces throughout the entire year. This research indicate that climate zone characteristics, urban environmental conditions, and thermal comfort requirements of residents must be accounted for in local-scale scientific planning and design, i.e., for urban canyon streets and residential estates.

    Full Text Available Gaining increasing popularity within the fitness sector, CrossFit® serves as an appealing and efficient high intensity training approach to develop strength and endurance on a functional level; and music is often utilized to produce ergogenic effects. The present randomized, controlled, crossover study aimed at investigating the effects of music vs. non-music on performance, physiological and psychological outcomes. Thirteen (age: 27.5, standard deviation (SD 6.2 years, healthy, moderately trained subjects performed four identical workouts over two weeks. The order of the four workouts (two with, and two without music, 20 min each was randomly assigned for each individual. Acute responses in work output, heart rate, blood lactate, rate of perceived exertion, perceived pain, and affective reaction were measured at the 5th, 10th, 15th, and 20th min during the training sessions. Training with music resulted in a significantly lower work output (460.3 repetitions, SD 98.1 vs. 497.8 repetitions, SD 103.7; p = 0.03. All other parameters did not differ between both music conditions. This is partly in line with previous findings that instead of providing ergogenic effects, applying music during CrossFit® may serve as a more distractive stimulus. Future studies should separate the influence of music on a more individual basis with larger sample sizes.

    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.

    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.

    Humor is a uniquely human quality whose neural substrates remain enigmatic. The present report combined dynamic, real-life content and event-related functional magnetic resonance imaging (fMRI) to dissociate humor detection ("getting the joke") from humor appreciation (the affective experience of mirth). During scanning, subjects viewed full-length episodes of the television sitcoms Seinfeld or The Simpsons. Brain activity time-locked to humor detection moments revealed increases in left inferior frontal and posterior temporal cortices, whereas brain activity time-locked to moments of humor appreciation revealed increases in bilateral regions of insular cortex and the amygdala. These findings provide evidence that humor depends critically upon extant neural systems important for resolving incongruities (humor detection) and for the expression of affect (humor appreciation).

    Full Text Available Pulpitis is an inflammation process on dental pulp tissue, and usually as the continuous of caries. The microorganism in the caries is a potential immunogenic triggering the immune respons, both humoral and celluler immune responses. 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 The size and distribution of leaf area determine light interception in a crop canopy and influence overall photosynthesis and yield. Optimized plant architecture renders modern maize hybrids (Zea mays L. more productive, owing to their tolerance of high plant densities. To determine physiological and yield response to maize plant architecture, a field experiment was conducted in 2010 and 2011. With the modern maize hybrid ZD958, three plant architectures, namely triangle, diamond and original plants, were included at two plant densities, 60,000 and 90,000 plants ha−1. Triangle and diamond plants were derived from the original plant by spraying the chemical regulator Jindele (active ingredients, ethephon, and cycocel at different vegetative stages. To assess the effects of plant architecture, a light interception model was developed. Plant height, ear height, leaf size, and leaf orientation of the two regulated plant architectures were significantly reduced or altered compared with those of the original plants. On average across both plant densities and years, the original plants showed higher yield than the triangle and diamond plants, probably because of larger leaf area. The two-year mean grain yield of the original and diamond plants were almost the same at 90,000 plants ha−1 (8714 vs. 8798 kg ha−1. The yield increase (up to 5% of the diamonds plant at high plant densities was a result of increased kernel number per ear, which was likely a consequence of improved plant architecture in the top and middle canopy layers. The optimized light distribution within the canopy can delay leaf senescence, especially for triangle plants. The fraction of incident radiation simulated by the interception model successfully reflected plant architecture traits. Integration of canopy openness is expected to increase the simulation accuracy of the present model. Maize plant architecture with increased tolerance of high densities is probably

    Biofilms have important effects on nutrient cycling in aquatic ecosystems. However, publications about the community structure and functions under laboratory conditions are rare. This study focused on the developmental and physiological properties of cultured biofilms under various phosphorus concentrations performed in a closely controlled continuous flow incubator. The results showed that the biomass (Chl a) and photosynthesis of algae were inhibited under P-limitation conditions, while the phosphatase activity and P assimilation rate were promoted. The algal community structure of biofilms was more likely related to the colonization stage than with the phosphorus availability. Cyanobacteria were more competitive than other algae in biofilms, particularly when cultured under low P levels. A dominance shift occurred from non-filamentous algae in the early stage to filamentous algae in the mid and late stages under P concentrations of 0.01, 0.1 and 0.6 mg/L. However, the total N content, dry weight biomass and bacterial community structure of biofilms were unaffected by phosphorus availability. This may be attributed to the low respiration rate, high accumulation of extracellular polymeric substances and high alkaline phosphatase activity in biofilms when phosphorus availability was low. The bacterial community structure differed over time, while there was little difference between the four treatments, which indicated that it was mainly affected by the colonization stage of the biofilms rather than the phosphorus availability. Altogether, these results suggested that the development of biofilms was influenced by the phosphorus availability and/or the colonization stage and hence determined the role that biofilms play in the overlying water.

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

    Science.gov (United States)

    Fiacconi, Chris M; Owen, Adrian M

    2015-01-01

    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.

    This article examines the influences of situational factors on user behaviour in usability tests. Sixty participants carried out two tasks on a computer-simulated prototype of a mobile phone. Employing a 3 x 2 mixed experimental design, laboratory set-up was varied as a between-subjects variable (presence of facilitator and two non-interactive observers, presence of facilitator or no person present) while task difficulty was manipulated as a within-subjects variable (low vs. high). Performance data, subjective measures and physiological parameters (e.g. heart rate variability) were taken. The results showed that the presence of non-interactive observers during a usability test led to a physiological stress response, decreased performance on some measures and affected the emotional state of test participants. The presence of a facilitator (i.e. a participating observer) also influenced the emotional state of the test participant. Practitioners involved in usability testing need to be aware of undue influences of observers, in particular, if the observers are non-interactive. The findings presented in this paper have implications for the practice of usability testing. They indicated a considerable influence of observers on test participants (physiology and emotions) and on the outcomes of usability tests (performance measures). This should be considered when selecting the set-up of a usability testing procedure.

    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.Keywords: humor, academic writing, text analysis, essay score, human rating

    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.

    Full Text Available Basic personality traits (e.g., extraversion have been found to be associated with the humor styles that individuals employ. In the present study, we were interested in determining whether pathological personality traits were also associated with humor styles. We examined the associations between the pathological personality traits captured by the Personality Inventory for the DSM-5 (PID-5 and humor styles in a sample of college students (N = 594. Negative affectivity and detachment were negatively associated with the affiliative and self-enhancing humor styles. Antagonism was positively associated with the aggressive humor style but negatively associated with the affiliative humor style. Disinhibition was positively associated with the aggressive humor style, whereas disinhibition and psychoticism were both positively associated with the self-defeating humor style. Discussion focuses on the implications of these findings and how they can expand our understanding of the connections between the darker aspects of personality and humor.

    The present study examined the relationships between four personality traits, humor styles, and happiness. Replicating previous research, happiness was positively correlated with four personality traits: extraversion, locus of control, self-esteem, and optimism. Further, happiness positively related to self-enhancing and affiliative humor styles; it related negatively to self-defeating and aggressive humor styles. Thus, happy people habitually engage in positive uses of humor and avoid engaging in negative uses of humor in daily life. We also found support for our hypothesis. People high in extraversion, locus of control, self-esteem, and optimism are happier because they engage in positive humor in daily life.

    Full Text Available Humor is universal. Nobody never gets involved with humor. It's the difference lies in its frequency and its target. One person may have a high sense of humor whereas another may have a low sense of humor. In fact every person needs humor in many communication activities. Though humor is only word game, people cannot avoid it. However, humor does not always cause the people to laugh. The creation of humor discourse can make use of articles, pictures, and sounds. Humor consumers assess humor variously. Sometimes people can feel happy when they hear humor; but sometimes they can feel infuriated, hateful, insinuated, or even aggrieved. This is caused by immeasurable humor context in each communication. It depends on the target that the humor creator wants.

    Summary.-This study examined how humor styles could mediate the effect of self-esteem on subjective happiness. 227 Hong Kong undergraduate students completed the Humor Styles Questionnaire, the Roxsenberg Self-esteem Scale, and the Subjective Happiness Scale. Results showed adaptive humor styles (affiliative humor and self-enhancing humor) significantly predicted self-esteem and subjective happiness and mediated the relationship between self-esteem and subjective happiness. Maladaptive humor styles (aggressive humor and self-defeating humor) did not strongly predict self-esteem or subjective happiness. The mediation effects of humor styles found in the present research provided useful suggestions for future studies.

    Understanding the environmental and biotic drivers of respiration at the ecosystem level is a prerequisite to further improve scenarios of the global carbon cycle. In this study we investigated the relevance of physiological phenology, defined as seasonal changes in plant physiological properties, for explaining the temporal dynamics of ecosystem respiration (RECO) in deciduous forests. Previous studies showed that empirical RECO models can be substantially improved by considering the biotic dependency of RECO on the short-term productivity (e.g., daily gross primary production, GPP) in addition to the well-known environmental controls of temperature and water availability. Here, we use a model-data integration approach to investigate the added value of physiological phenology, represented by the first temporal derivative of GPP, or alternatively of the fraction of absorbed photosynthetically active radiation, for modeling RECO at 19 deciduous broadleaved forests in the FLUXNET La Thuile database. The new data-oriented semiempirical model leads to an 8% decrease in root mean square error (RMSE) and a 6% increase in the modeling efficiency (EF) of modeled RECO when compared to a version of the model that does not consider the physiological phenology. The reduction of the model-observation bias occurred mainly at the monthly time scale, and in spring and summer, while a smaller reduction was observed at the annual time scale. The proposed approach did not improve the model performance at several sites, and we identified as potential causes the plant canopy heterogeneity and the use of air temperature as a driver of ecosystem respiration instead of soil temperature. However, in the majority of sites the model-error remained unchanged regardless of the driving temperature. Overall, our results point toward the potential for improving current approaches for modeling RECO in deciduous forests by including the phenological cycle of the canopy.

    Brain monoamines - such as noradrenaline (NA), dopamine (DA) and serotonin (5-HT) - regulate several important physiological functions, including the circadian rhythm. The purpose of this study was to examine changes in NA, DA and 5-HT levels in various brain regions and their effect on core body temperature (Tc), heart rate (HR) and locomotor activity (Act) in rats following exposure to an artificial light/dark (LD) cycle. For this, male Wistar rats were housed at an ambient temperature (Ta) of 23 °C and 50% relative humidity with free access to food and water. Rats were exposed to either natural (12 h:12 h) or artificial (6 h:6 h) LD cycles for 1 month, after which each brain region was immediately extracted and homogenized to quantify the amounts of NA, DA and 5-HT by high-performance liquid chromatography. Behavioural changes were also monitored by the ambulatory activity test (AAT). Notably, we found that artificial LD cycles disrupted the physiological circadian rhythms of Tc, HR and Act. Although the 5-HT levels of rats with a disrupted circadian rhythm decreased in cell bodies (dorsal and median raphe nuclei) and projection areas (frontal cortex, caudate putamen, preoptic area and suprachiasmatic nucleus) relative to the control group, NA levels increased both in the cell body (locus coeruleus) and projection area (paraventricular hypothalamus). No significant changes were found with respect to DA. Moreover, circadian rhythm-disrupted rats also showed anxious behaviours in AAT. Collectively, the results of this study suggest that the serotonergic and noradrenergic systems, but not the dopaminergic system, are affected by artificial LD cycles in brain regions that control several neural and physiological functions, including the regulation of physiological circadian rhythms, stress responses and behaviour.

    2014-09-01

    Dietary nitrate supplementation, usually in the form of beetroot juice, has been heralded as a possible new ergogenic aid for sport and exercise performance. Early studies in recreationally active participants indicated that nitrate ingestion significantly reduces the O2 cost of submaximal exercise and improves performance during high-intensity endurance exercise. Subsequent studies have begun to address the physiological mechanisms underpinning these observations and to investigate the human populations in whom, and the exercise conditions (high- vs. low-intensity, long- vs. short-duration, continuous vs. intermittent, normoxic vs. hypoxic) under which, nitrate supplementation may be beneficial. Moreover, the optimal nitrate loading regimen in terms of nitrate dose and duration of supplementation has been explored. Depending on these factors, nitrate supplementation has been shown to exert physiological effects that could be conducive to exercise performance enhancement, at least in recreationally active or sub-élite athletes. This article provides a "state-of-the-art" review of the literature pertinent to the evaluation of the efficacy of nitrate supplementation in altering the physiological determinants of sport and exercise performance.

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.

  9. 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

    Full Text Available 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.

    To compare and evaluate two methodologies, entire-sampling and micro-sampling for the harvesting of vitreous humor, the vitreous humor of rabbits were sampled with the two methods respectively, and the concentrations of calcium, chlorine, potassium, sodium and phosphorus of the were measured. The results showed that the differences in the variance coefficient and two-eye concentrations of micro-sampled specimens were less than those of the entire-sampled specimens. In the micro-sampling group, the concentrations of repeated micro-sampling showed no differences among different groups (P>0.05) and the intra-ocular fluid dynamics did not have significant influence on post-mortem sampling. The sampling technique may affect the concentrations of specimen collected.Our study suggests that micro-sampling is less influenced by the human factor and is reliable, reproducible, and more suitable for forensic investigation.

    Full Text Available The aim of this study was to investigate somatic properties and physiological capacity, and analyze kinematic parameters in the 200 m breaststroke swimming race. Twenty-seven male swimmers participated in the study. They were 15.7±1.98 years old. Their average height was 1.80 ± 0.02 m and lean body mass (LBM was 62.45 ± 8.29 kg. Physiological exercise capacity was measured in two separate 90 sec. all-out tests, one for the arms and second for legs. During the tests total work of arm cranking (TWAR and cycling (TWLG as well as peak of VO2 for arm (VO2peakAR and leg (VO2peakLG were measured. The underwater swimmers body movements were recorded during the all-out swimming 200m breaststroke speed test using an underwater camera installed on a portable trolley. The swimming kinematic parameters and propulsive or non-propulsive movement phases of the arms and legs as well as average speed (V200, surface speed (V200surface and swimming speed in turn zones (V200turns were extracted. V200surface was significantly related to the percentage of leg propulsion and was shown to have large effect on VO2peakLG in the Cohen analysis. V200turns depended significantly on the indicators of physiological performance and body structure: TWAR, VO2peak LG and LBM, LBM, which in turn strongly determined the measured results of TWAR, TWLG, VO2peakAR and VO2peakLG. The V200turns and V200surface were strongly associated with V200, 0.92, p < 0.001 and 0.91, p < 0.001 respectively. In each lap of the 200m swimming there was an increased percentage of propulsion of limb movement observed simultaneously with a reduction in the gliding phase in the breaststroke cycles.

    Fledging is a major life transition for birds, when juveniles move from the safety of a nest into an environment where they must find food and avoid predators. The timing of fledging within a season can have significant effects on future survival and breeding success. Proximate triggers of fledging are unknown: though wing development is likely a primary factor, other physiological changes, such as elevated plasma corticosterone (CORT), may affect fledging behavior. Laysan Albatross (Phoebastria immutabilis) chicks have an extended post-hatching period during which they reach 150% of adult mass. However, approaching fledging, chicks fast for days to weeks and lose mass while still putting energy into feather growth. We evaluated chick morphology and physiology to elucidate proximate triggers of fledging. As in some other species, CORT increased as chicks fasted and lost body mass. At the same time, corticosteroid binding globulin (CBG) declined, thus amplifying free CORT prior to fledging. Once chicks reached a morphological threshold, free CORT levels predicted how long they stayed at the colony: chicks with higher free CORT fledged sooner. To perturb the relationship between body condition, endocrine physiology, and fledging behavior, we supplementally fed chicks for the month before fledging. Fed birds had a slower decrease in body mass, slower decrease in CBG, slower increase in free CORT, and stayed at the colony longer after reaching a morphological threshold. Our study suggests that as chicks lose mass, free CORT acts as a signal of energetic or nutritional state to adjust the timing of fledging. Copyright 2010 Elsevier Inc. All rights reserved.

    Avian yolk fatty acids (FA) composition is influenced by two main factors: maternal diet and genetic factors that regulate FA metabolism. However, due to embryonic developmental requirements, yolk FA are thought to be physiologically constrained and less useful for dietary and trophic studies. We assessed the relative contributions of diet and physiological constraints in determining the yolk FA composition of a marine bird, the gentoo penguin (Pygoscelis papua) by comparing FA signatures of yolks and prey between a captive, controlled- feeding experiment and a wild population. Captive and wild yolk FA signatures differed even though both groups' yolk lipids were composed primarily of three FA (16:0, 18:0 and 18:1n-9). Differences were due to FA occurring in relatively low abundance, but which mirrored differences in the FA composition of diets. However, yolk FA signatures were correlated across three penguin species suggesting that common developmental constraints can be relatively more important than species-specific differences in diet or egg-laying physiology. While yolk FA are constrained, several minor components of yolk FA are reflective of diets and the calibration coefficients resulting from this study have the potential to be incorporated into predictive models and allow for quantitative dietary and trophic studies using FA analysis of penguin egg yolks.

    Mn and Fe are two important micronutrients of paddy soils derived from red earths.Rice(Oryza sativa L.)oranging physiological diease in newly reclaimed red rarths is related to Fe toxicity.There have been considerable studies on Mn and Fe counteraction,but influence of Mn and Fe counteration on rice oranging physiological disease still remains unknown.This paper is to study,using two soils from USA and China respectively,the relationship between Nn and Fe counteraction and the physiological disease.Analysis for water soluble and extractable Fe and Mn showed that Mn/Fe ratios of the red earths were lower than those of the paddy soils.Fertilizing with Mn raised Mn/Fe and reduced oranging leaves,improved growth and increased yields.Analysis with electron probe showed that Mn treatment had less Fe deposit in root epidermis and more Ca and Si in roots.The results indicated that fertilizing with Mn could correct Fe toxicity.How to apply Mn and Fe counteraction in practice is worth further studying.

    Full Text Available Little is currently known regarding competitor influence on pacing at the start of an event and in particular the subsequent effect on the remaining distance. The purpose of the present study was to investigate the influence of starting pace on the physiological and psychological responses during cycling time trials (TT utilising an innovative approach allowing pace to be accurately and dynamically replicated, as well as deceptively manipulated. Ten competitive male cyclists completed five 16.1 km TT, two baseline trials performed alone (BLs, and three with a simulated, dynamic avatar of which they were to match the pace of for the initial 4 km. The avatar represented either the cyclist’s fastest BL performance (NORM, 105% (FAST, or 95% (SLOW, of fastest BL performance (FBL. Physiological and psychological responses were measured every quartile of the TT. Despite manipulating a starting speed of ± 5% of fastest previous performance, there was no effect on overall 16.1 km TT performance. Manipulated starting strategies did however evoke different physiological and perceptual responses. Whole trial differences found that SLOW produced lower HR, VO2, BLa and RPE than FBL (p ≤ 0.03 and higher SE than FAST (p ≤ 0.03. Additionally, FAST had greater internal attention than NORM (p < 0.04. Over time all psychological and physiological variables had a significant condition x quartile interaction in the initial or second quartile mediated by the prescribed starting strategies. Furthermore, RPE, affect and internal attention remained elevated throughout FAST despite an attenuation in pace during self-selection of pace. There were no differences in performance time when manipulating a 16.1km cycling TT starting strategy. A slow start, encouraged greater positive perceptions, less negative physiological consequences than a faster start, and produces no impairment to performance time. It would therefore be considered an advantage in a non

    Full Text Available In this review, we compile information about the physiologic responses of goats to north-eastern Brazil’s semiarid environment and suggest some strategies to avoid the thermal discomfort of these small ruminants. Due to recent weather changes, the number of studies seeking to improve animal welfare has intensified to minimize the economic losses on animal production in the tropics. Among the climatic variables, the high room temperature, air humidity, and direct solar radiation are the main causes of physiological discomfort in animals that decrease their productivity. Therefore, it is very important to study the components that interact in the thermoregulation process, the consequences of disequilibrium in this process, and ways to ease these effects, aiming to provide thermal comfort to and seek the animal welfare of the animals. Therefore, it is essential to know the interaction between animals and the environment and the adaptability of the species and breeds that are exploited to make decisions about farming systems and management strategies to maximize productivity.

    The NIMH Research Domain Criteria (RDoC) initiative aims to describe key dimensional constructs underlying mental function across multiple units of analysis-from genes to observable behaviors-in order to better understand psychopathology. The acute threat ("fear") construct of the RDoC Negative Valence System has been studied extensively from a translational perspective, and is highly pertinent to numerous psychiatric conditions, including anxiety and trauma-related disorders. We examined genetic contributions to the construct of acute threat at two units of analysis within the RDoC framework: (1) neural circuits and (2) physiology. Specifically, we focused on genetic influences on activation patterns of frontolimbic neural circuitry and on startle, skin conductance, and heart rate responses. Research on the heritability of activation in threat-related frontolimbic neural circuitry is lacking, but physiological indicators of acute threat have been found to be moderately heritable (35-50%). Genetic studies of the neural circuitry and physiology of acute threat have almost exclusively relied on the candidate gene method and, as in the broader psychiatric genetics literature, most findings have failed to replicate. The most robust support has been demonstrated for associations between variation in the serotonin transporter (SLC6A4) and catechol-O-methyltransferase (COMT) genes with threat-related neural activation and physiological responses. However, unbiased genome-wide approaches using very large samples are needed for gene discovery, and these can be accomplished with collaborative consortium-based research efforts, such as those of the Psychiatric Genomics Consortium (PGC) and Enhancing Neuro Imaging Genetics through Meta-Analysis (ENIGMA) Consortium.

    Full Text Available We developed a valid experimental model of dosed burn to study the influence of polarized light on burns, obtained from open flame, with a possibility of their basic parameters regulation. In the article there are characterized the expression and peculiarities of inflammation reaction process, development and dynamics of granulation growth and the process of burn wound epithelization. We observed polarized light positive influence on burn wound regeneration and speed of its healing. In particular, we singled out: derma depth alteration restriction and secondary alteration of skin tissues and sub muscles, activation of mechanisms, that restrict inflammation, fibroblasts proliferation increase, formation of granulations and neo-angiogenesis, stimulation of proliferation, keratinocytes' migration and wound surface epithelialization under the influence of polarized light. We singled out expressed antinociceptive, anti-stress and adaptive-stimulating effects of polarized light on central nervous system functional state at burns.

    2016-04-01

    Full Text Available Over the years with changes in both production and marketing aspects of the operation of goats and sheep has been highlighted and is widespread throughout the world. The sheep and goat production systems are affected by several restrictive elements that can compromise their development, among which stands out the adverse weather conditions that contribute to the reduction of the herd productivity. In conditions of thermal stress, the animals begin a series of mechanisms regulated by hormones and coordinated by the nervous system and the endocrine system. In this context, the objective was to make a literature review on hormone physiology in control of heat stress in sheep and goats. Hormonal changes detected in animals under heat stress affects both their productive performance as the reproductive, predisposing the onset of diseases, stunted growth or reproductive harm. Changes in behavior are the first visible signs triggered by hormonal changes due to thermal stress.

    The vegetation of the Copsa Mica(Romania) zone is often visibly affected by the noxious elements existing in the atmosphere, especially sulfur dioxide. Comparative investigations were undertaken to examine some physiological and biochemical processes in plants from polluted as well as control zones. Water content (total and fractions of free and bound water), stomata condition and hydrogen ion concentration in cellular sap were analyzed; the results of these analyses showed that at the level of all the studied processes, modifications occur, which are sometimes substantial. In laboratory experiments with Pelargonium plants grown in an atmosphere containing sulfur dioxide, a foliar symptomatology was obtained, as well as a chromatogram of free amino acids different to that of controls

    Full Text Available The lumbar spine is subjected to considerable stress during many athletic efforts. The purpose of this study was to assess the effects of physiological loading on the lumbar spine in national male players of different games, which may be predictive of the future development of low back pain and injury symptoms. Thirty-four national players (12 cricket players, 12 field hockey players, and 10 basketball players underwent magnetic resonance imaging, and selected geometric variables including intervertebral disc angles, the Farfan ratio, the lumbar body index, the compression deformity ratio, the biconcave deformity ratio and the anterior wedge deformity ratio were measured using KINOVEA-0.8.15 software and syngo fast view software and calculated using specific formulas. The results indicated a significant difference in the intervertebral disc angle between the three groups at the L2/3, L3/4 and L4/5 levels. In relation to the lumbar vertebral body shape and size, significant differences were found in the lumbar index at the L2 level, in the biconcave deformity at the L1 and L2 levels and in relation to the anterior wedge deformity at L2 between the three selected groups. Our data suggest that the different physiological loadings in the selected sports play an important role in the development of degenerative changes of the lumbar spine, which may be considered a risk factor for future injury and/or low back pain in each specific sport because of the unique demands of each discipline.

    Muscle mechanical output such as force and power are governed by highly nonlinear intrinsic muscle properties associated with different muscle fiber types and are influenced by training and age. Many of the interactions between these properties pose trade-offs such that an individual's anthropometrics and muscle morphology may allow an athlete to excel in one sport but not in others. Advanced modeling and simulation techniques are powerful tools to gain insight into performance limits, optimal equipment designs, and mechanisms that may lead to injury. Recent technological innovations have produced faster running tracks, bicycles, speed skates, and swimming pools. This review discusses the influence of intrinsic muscle properties in sports and how advanced technology can be used to extend the limits of human performance.

    2015-01-01

    Hormones exert many actions in the brain. Their access and effects in the brain are regulated by the blood-brain barrier (BBB). Hormones as other substances may enter the brain and vice versa either by paracellular way requiring breaching tight junctions stitching the endothelial cells composing the BBB, or by passage through the cells (transcellular way). Hormones influence both ways through their receptors, both membrane and intracellular, present on/in the BBB. In the review the main examples are outlined how hormones influence the expression and function of proteins forming the tight junctions, as well as how they regulate expression and function of major protein transporters mediating transport of various substances including hormone themselves.

    In veterinary medicine, the characterization of a drug's pharmacokinetic properties is generally based upon data that are derived from studies that employ small groups of young healthy animals, often of a single breed. In Part I of the series, we focused on the potential influence of disease processes, stress, pregnancy and lactation on drug pharmacokinetics. In this Part II of the series, we consider other covariates, such as gender, heritable traits, age, body composition, and circadian rhythms. The impact of these factors with respect to predicting the relationship between dose and drug exposure characteristics within an animal population is illustrated through the use of Monte Carlo simulations. Ultimately, an appreciation of these potential influences will improve the prediction of situations when dose adjustments may be appropriate. © 2010 Blackwell Publishing Ltd.

    Effects of physiological and/or psychological inter-individual differences on the resting brain state have not been fully established. The present study investigated the effects of individual differences in basal autonomic tone and positive and negative personality dimensions on resting brain activity. Whole-brain resting cerebral perfusion images were acquired from 32 healthy subjects (16 males) using arterial spin labeling perfusion MRI. Neuroticism and extraversion were assessed with the Eysenck Personality Questionnaire-Revised. Resting autonomic activity was assessed using a validated measure of baseline cardiac vagal tone (CVT) in each individual. Potential associations between the perfusion data and individual CVT (27 subjects) and personality score (28 subjects) were tested at the level of voxel clusters by fitting a multiple regression model at each intracerebral voxel. Greater baseline perfusion in the dorsal anterior cingulate cortex (ACC) and cerebellum was associated with lower CVT. At a corrected significance threshold of p personality traits (amygdala, caudate, etc.) during active task processing. The resting brain state may therefore need to be taken into account when interpreting the neurobiology of individual differences in structural and functional brain activity.

    This study investigated the effects of obesity and ambient temperature on physiological responses and markers of oxidative stress to submaximal exercise in obese and lean people. Sixteen healthy males were divided into an obese group (n=8, %fat: 27.00±3.00%) and a lean group (n=8, %fat: 13.85±2.45%). Study variables were measured during a 60 min submaximal exercise test at 60% VO2max in a neutral (21±1°C) and a cold (4±1°C) environment. Heart rate, blood lactate, rectal temperature, serum levels of malondialdehyde (MDA) and superoxide dismutase (SOD) were measured at rest, during exercise and in recovery. Heart rate of both groups was significantly lower (P<0.05) in the cold than the warm environment, but there were no significant differences between the two groups. Serum SOD activity increased to a significantly greater extent (P<0.05) in the cold than the neutral environment, and remained elevated for longer during exercise in the obese group than the lean group. Serum MDA level during submaximal exercise was not significantly different between conditions or groups. Cold stress in exercise may challenge antioxidant defence mechanisms in obese subjects, but lipid peroxidation remains unchanged. PMID:24899779

    The development of nanotechnology has generated new means of disease diagnosis and treatment. Infectious diseases, including leishmaniasis, malaria, etc., have benefited from the advent of new nanomaterials and/or nanodevices capable of detecting specific antigens and antibodies with high specificity and low cost. In this paper, we present an investigation on a single-celled protozoan Leishmaniasis parasite, a disease considered of standard infectivity, given the high degree of immunological specificity. Natural rubber (NR) membranes incorporating gold nanoparticles (GNPs) were placed in the culture medium and the physiological behavior of Leishmania brasiliensis promastigotes was evaluated. The natural rubber membranes containing GNPs decreased the population growth rate, showing a lower index of living promastigotes (attached to the membrane surface) depending on the amount of nanoparticles deposited in the membrane surface. Such membranes may be used to develop a flexible band-aid for skin lesions from degenerative infection state, inhibiting the population growth of parasites in the lesions. In addition, natural rubber membranes would also stimulate angiogenesis in damaged tissues.

  6. Humoral immunity in Hansen's Disease

    Directory of Open Access Journals (Sweden)

    Waldenise Cossermelli-Messina

    Full Text Available For many years immune response in leprosy has been studied. Since 1960 several reports dealing with humoral immunity have been described in the literature. Different autoantibody rates occur in leprosy. There is an increase in the prevalence of autoantibodies in elderly patients with long standing disease, in lepromatous leprosy and in those with reactional states. The diferences in rates among various studies are attributed to different methods and variations among patient samples concerning age, gender, polar forms, therapy and other elements. The prevalence of numerous antibodies, immune complexes, cryoglobulins and complement levels have been studied by many authors. This also highlights the importance of the more recent reviews of anti-Mycobacterium leprae glycolipid antibodies such as the anti-phenolic glycolipid-I antibodies in which titers are variable and depend on genetic factors.

    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.

    Aim of the study: To evaluate the morpho-physiological changes of Acacia auriculiformis in response to seawater induced salinity stress along with its tolerance limit. Area of study: Bangabandhu Sheikh Mujibur Rahman Agricultural University, Bangladesh. Material and methods: Three saline treatments (4, 8, 12 dS m-1) were applied to six-month aged Acacia auriculiformis seedlings from January 2014 to June 2014 and the tap water was used as control treatment. To observe salinity effects, the following parameters were measured by using various established techniques: plant height and leaf number, plant biomass, shoot and root distribution as well as shoot and root density, water uptake capacity (WUC), water saturation deficit (WSD) and water retention capacity (WRC), exudation rate, and cell membrane stability. Main results: Diluted seawater caused a notable reduction in shoot and root distribution in addition to shoot and root density, though plant height, leaf number and plant biomass were found to be decreased to some extent compared to control plants. Water status of the plant also altered when plants were subjected to salinity stress. Nevertheless, membrane stability revealed good findings towards salinity tolerance. Research highlights: Considering the above facts, despite salinity exerts some negative effects on overall plant performance, interestingly the percent reduction value doesn’t exceed 50% as compared to control plants, and the plants were successful to tolerate salinity stress till the end of the experiment (150 days) through adopting some tolerance mechanisms.

Hence, even though environmental bacteria are able to deal with many stressful situations, environmental stressors can be bottlenecks for pollutant degradation by influencing directly on the level of catabolic gene expression. Finally the study investigated whether findings...... on pollutant degradation from in vitro test tube conditions have any relevance when increasing the complexity to approach conditions that degrader bacteria encounter in the actual environment.......Bacteria and other microorganisms play an important role for removal of pollutants released into the environment, either deliberately or accidentally. In particular, soils are reservoirs for microorganisms carrying the catalytic potential for breakdown of otherwise toxic and often recalcitrant...

    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.

    The effects of two-year early season ozone exposure on physiological and biochemical stress response were investigated in model plant communities. Achillea millefolium and Veronica chamaedrys target plants were grown in monocultures and in mixed cultures with Poa pratensis (phytometer) and exposed in open-top chambers over two years for five weeks to charcoal-filtered (CF) air plus 25 nl l{sup -1} O{sub 3} (control) and non-filtered (NF) air plus 50 nl l{sup -1} O{sub 3}. Significant O{sub 3} effects were detected in different physiological and biochemical parameters, evidencing interspecific differences in metabolic stress responses and a strong influence of the competition factor. O{sub 3} induced strong oxidative effects in Achillea irrespective to the different growth modality. Veronica showed less O{sub 3}-induced effects in monoculture than when grown in competition with the phytometer. Poa exhibited a different behaviour against O{sub 3} depending on the species in competition, showing an overall higher sensitivity to O{sub 3} when in mixture with Achillea. - The competition between species modulates the ozone effect in a short-term.

    Full Text Available The main objective of this study is to see how the royal insecticide influences the energetic metabolism, the breathing rhythm, the blood sugar and the number of red blood cells at the Prussian carp individuals. Experimental samples were subjected to under-lethal concentrations of 0.00125, 0.0025 and 0.005 ml/l royal insecticide from 24 to 336 hours. The physiologic parameter with the highest growth rate was the oxygen consumption, which, at the concentration of 0.005 ml/l grew by 50.81% in 168 hours, compared to the witness values, registering the value of 216.66 ml oxygen/kilo/hour compared to 143.66 oxygen ml/kilo/hour. The blood sugar was the single physiological biomarker which decreased, so that the lowest value was 48 mg/dl, 29.62% approximately lower compared to the witness value (68.2 mg/dl at a concentration of 0.00125 ml/l.

    Full Text Available The antioxidant influence on the physiological-biochemical parameters of productive animals is one of the most important directions in modern animal science. Phenozan is a synthetic antioxidant with high biological activities including those for animals. The positive effects of phenozan on the physiological-biochemical parameters of the mink blood were found. These effects are leading to the intensive growth, strong health, enhancement of the mink fur quality, and so forth. The total amount of the erythrocytes in the mink blood increased by about 4-5% due to phenozan inclusion in the mink diet. Even a more significant increase was found in hemoglobin content in the mink blood and erythrocytes (by about 9.5% and 8.8%, resp. due to phenozan inclusion of 100 mg/day, whereas it was found only by about 6.1–5.3% or 5.5–0.3%, owing to phenozan inclusion of 50 or 150 mg/day. For many other parameters the optimal phenozan concentration was about 100 mg/day per head according to the result obtained for all studied animal groups. Thus, phenozan can be successfully used as a biologically active compound for mink nutrition and is recommended for other farm animals.

    Objective The aim of the present study was to examine the influence of karate practice level (national vs international level) and sex (women vs men) on physiological and perceptual responses in three modern karate training modalities (tactical-technical (TT), technical-development (TD), and randori). Method The study included 18 karatekas participating in an eight-session training camp of four TT, two TD, and two randori. During each session, the percentage of maximal heart rate (HR), blood lactate concentration [La-], and rating of perceived exertion (RPE) were assessed. Results The main results showed that the percentage of maximal HR was significantly higher in women than in men regardless of practice level or training modality (70.3 ± 4.1 vs 66.2 ± 6.3, respectively). Moreover, [La-] and RPE were significantly lower in international-level karatekas compared with their national-level counterparts whatever the sex or training modality ([La-] = 11.4 ± 2.6 vs 8.3 ± 2.4 mmol · L-1 and RPE = 3.6 ± 1.2 vs 4.3 ± 1.5, respectively). Last, physiological and perceptual responses were significantly higher during randori in comparison with TT and TD for both sexes. Conclusion The combination of [La-] and RPE thus seems to be a good indicator for discriminating between national- and international-level karatekas, and randori seems to be an effective means to reproduce official karate sparring.

  19. Identification of differences in human and great ape phytanic acid metabolism that could influence gene expression profiles and physiological functions

    Directory of Open Access Journals (Sweden)

    2010-10-01

    Full Text Available Abstract Background It has been proposed that anatomical differences in human and great ape guts arose in response to species-specific diets and energy demands. To investigate functional genomic consequences of these differences, we compared their physiological levels of phytanic acid, a branched chain fatty acid that can be derived from the microbial degradation of chlorophyll in ruminant guts. Humans who accumulate large stores of phytanic acid commonly develop cerebellar ataxia, peripheral polyneuropathy, and retinitis pigmentosa in addition to other medical conditions. Furthermore, phytanic acid is an activator of the PPAR-alpha transcription factor that influences the expression of genes relevant to lipid metabolism. Results Despite their trace dietary phytanic acid intake, all great ape species had elevated red blood cell (RBC phytanic acid levels relative to humans on diverse diets. Unlike humans, chimpanzees showed sexual dimorphism in RBC phytanic acid levels, which were higher in males relative to females. Cultured skin fibroblasts from all species had a robust capacity to degrade phytanic acid. We provide indirect evidence that great apes, in contrast to humans, derive significant amounts of phytanic acid from the hindgut fermentation of plant materials. This would represent a novel reduction of metabolic activity in humans relative to the great apes. Conclusion We identified differences in the physiological levels of phytanic acid in humans and great apes and propose this is causally related to their gut anatomies and microbiomes. Phytanic acid levels could contribute to cross-species and sex-specific differences in human and great ape transcriptomes, especially those related to lipid metabolism. Based on the medical conditions caused by phytanic acid accumulation, we suggest that differences in phytanic acid metabolism could influence the functions of human and great ape nervous, cardiovascular, and skeletal systems.

    The results generated from the NIH funded Human Microbiome Project (HMP) are necessarily tied to the overall mission of the agency, which is to foster scientific discoveries as a basis for protecting and improving health. The investment in the HMP phase 1 accomplished many of its goals including the preliminary characterization of the human microbiome and the identification of links between microbiome diversity and disease states. Going forward, the next step in these studies must involve the identification of the functional molecular elements that mediate the positive influence of a eubiotic microbiome on health and disease. This review will focus on recent advances describing mechanistic events in the intestine elicited by the microbiome. These include symbiotic bacteria-induced activation of redox-dependent cell signaling, the bacterial production of short chain fatty acids and ensuing cellular responses, and the secretion of bacteriocins by bacteria that have anti-microbial activities against potential pathogens.

    The influence of fatiguing stimuli applied to the quadriceps femoris on the tremor of the index finger on sixteen healthy subjects has been investigated, by measuring the acceleration and the electromyography activity of the extensor digitorum at two different speeds. No significant changes in the basal condition could be measured at 0.52 rad/s. However, at 1.05 rad/s the tremor amplitude (12.23%, p<0.05) and the electromyography activity (20.19%, p<0.05) increased in the time domain. In the frequential domain, the peak associated to the acceleration increased in 26.30% (p<0.05), while the electromiography activity experienced an increase of 81.34% (p<0.05). The largest change in frequency took place in the range 7-17 Hz. The discussion of the results leads to the conclusion that the supraespinal mechanism is responsible for the measured effect.

    The present study was designed to investigate whether calorie source influences sodium and water metabolism and sympathetic activity during parenteral nutrition (PN). 20 New Zealand rabbits were starved until a mean weight loss of 18% was achieved and then re-fed for 6 days with 2 formulae of PN with different glucose-fat proportions. In the Glucose group (n = 9), 70% of non-protein calories were given as glucose while in the Lipid group (n = 11), 70% of non-protein calories were administered as lipids. Rabbits with a high glucose intake showed significantly higher weight gain (151 +/- 87 vs. 52 +/- 7 g, P = 0.01), water cumulative balance (542 +/- 132 vs. 411 +/- 87 ml; P = 0.02) and urinary metanephrine excretion (0.42 +/- 0.12 vs. 0.30 +/- 0.1 mumol/d, P = .03). Only in this group, urinary metanephrines correlated positively with water and sodium balances (r2 = 0.6; P = 0.02 and r2 = 0.7; P = 0.009 respectively). The Glucose group showed 2 different responses and in a second experiment 10 additional rabbits were added to this group to allow a statistical analysis of the response pattern: half of the animals increased their extracellular water (ECW) compartment while the remaining animals did not. The former group had higher sodium balance (13.9 +/- 8 vs. 4.3 +/- 5; P = 0.004) and wet lung weight (8.9 +/- 0.9 vs. 7.9 +/- 0.8; P wate and sodium balances. Plasma aldosterone concentration at the end of starvation period influences sodium retention and ECW expansion during high glucose re-feeding.

    Full Text Available This paper discusses humorous stories collected in the village of Brekovo near Arilje; the stories were created in the first half of the 20th century and noted down by Momčilo Jovanović, a villager from Brekovo. Later on, in the 1980's, the stories were passed down to the author of this paper. These narrations are mostly short stories and anecdotes; in a very realistic fashion, the stories depict life and culture of the Dinaric race from old Vlah - Zlatibor cultural area, namely, the type of person also known as "Era", well-known for its wittiness, smartness and wisdom. Based on the analysis of seven Era-stories, the author identified the social and cultural values highlighted in the stories (such as attitudes toward authorities intergenerational relationship, status of women, power relations between townsmen and peasants, propensity toward justice and truth. In summary, the stories document the mutual influence between traditional culture and the Era personality in this particular rural region; therefore, they could contribute to studies on character traits of the inhabitants in a given area of western Serbia.

    Full Text Available This investigation examines a sexual selection-based argument regarding humor’s role in courtship (i.e., humor production signals intelligence/creativity. Lens model (n =100 analyses suggest that humor production on Facebook profiles were self-reported and perceived to be associated with extroversion, not intelligence. Study 2 (n = 289 found that extroversion was associated humor production, but high school and college grade point average and American College Test (ACT scores were not. In Study 3, pairs of opposite-sex strangers (n = 102 interacted for 10–12 min. Males’ humor production and females’ responsive laughter were both associated with females’ dating interest. Both partners’ dating interest was associated with simultaneous laughter. Without support for the sexual selection argument, three alternative explanations of humor’s role in courtship are discussed.

    Full Text Available The article studies the influence of polymeric in the form of formers and growth regulators on the growth and development of rice plants when grown in saline conditions. We controlled the effect of salinity on grows regulators and vigor, seed germination, root and shoot weight, the content of photosynthetic pigments parameters, induction curves of delayed fluorescence, the indicators of structure of harvest, grain yield. It was found, that pre-sowing seed soaking in solutions of polymer grows regulators has a stimulating effect on the growth and development of rice plants in the early stages: we significantly increased germination and emergence, dry weight of root and shoot compared to control. At different stages of ontogeny rice, the absolute content of pigments in the leaves and the relationship between the individual variants change. The absolute content of pigments in leaves and their relationship between experiences at different stages of ontogeny change. In the period of intensive vegetative growth from seedling stage the content of total chlorophyll is maximum, and by the end of the growing season it decreases. It can be assumed that the salinity of the substrate significantly reduces the productivity of photosynthesis in young plants, possibly due to imbalance of ions in the cell, the older it gets – the weaker the phenomenon is and even becomes reversed. The second maximum IR ZF increases during the growing season from germination to flowering, then decreases to the beginning of ripening in all embodiments. The same dynamics is characteristic of the magnitude of the proton gradient in the membranes of chloroplasts tylakoids. Salt protection effect of growth regulators on grain yield is significant on both backgrounds of mineral nutrition

    Mechanical ventilation is widely recommended for reptiles during anesthesia, and while it is well-known that their low ectothermic metabolism requires much lower ventilation than in mammals, very little is known about the influence of ventilation protocol on the recovery from anesthesia. Here, 15 ball pythons (Python regius) were induced and maintained with isoflurane for 60min at one of three ventilation protocols (30, 125, or 250mlmin(-1)kg(-1) body mass) while an arterial catheter was inserted, and ventilation was then continued on 100% oxygen at the specified rate until voluntary extubation. Mean arterial blood pressure and heart rate (HR) were measured, and arterial blood samples collected at 60, 80, 180min and 12 and 24h after intubation. In all three groups, there was evidence of a metabolic acidosis, and snakes maintained at 30mlmin(-1)kg(-1) experienced an additional respiratory acidosis, while the two other ventilation protocols resulted in normal or low arterial PCO2. In general, normal acid-base status was restored within 12h in all three protocols. HR increased by 143±64% during anesthesia with high mechanical ventilation (250mlmin(-1)kg(-1)) in comparison with recovered values. Recovery times after mechanical ventilation at 30, 125, or 250mlmin(-1)kg(-1) were 289±70, 126±16, and 68±7min, respectively. Mild overventilation may result in a faster recovery, and the associated lowering of arterial PCO2 normalised arterial pH in the face of metabolic acidosis. Copyright © 2017 Elsevier Inc.

    Directory of Open Access Journals (Sweden)

    Desimir Mladenović

    2010-06-01

    Full Text Available Osteogenesis is the process of bone tissue forming, i.e. bone or callus regeneration. This process is influenced by many factors, and the degree of bone fragments’ stability and vascularization in the fracture area are the basic local factors which determine the nature of reparative process. Regenerative process of all bone structures increases with increasing of blood supply.The distal lower leg has its specific biomechanical features, and plays an important role in the transfer of body weight to foot. The distal part of tibia has a small diameter, which as a consequence has reduced diameter in medullar cave. Through this anatomic feature, the medullar network in the lower tibia part is also reduced.As for anatomic aspect, vascularization in the lower end of tibia is poor. It primarily depends on periosteal vascularization, because medullar vascularization is reduced. Fasciae, tendons and skin cover the lower part of the leg, and there is no muscle mass. These tissues have poor vascular network and that is why the extraosseous blood circulation in tibia is poor, and does not participate in the osteogenesis process. For these reasons, distal lower leg represents a predelection site for delayed osteogenesis and pseudoarthrosys development.Osteosynthesis causes secondary damage to bone and soft tissue circulation. The screw plate damages the periosteal circulation – in the lower part of tibia it is the main source of vascularization, and for this reason, this method of osteosynthesis should not be applied. The external fixator has a sparing role regarding vascularization, and that is the reason why this method is recommended for fracture stabilization at the level of distal lower leg.

    Background The construction of tissue-engineered corneal endothelium needs the functional seeding cells,so how to culture a large amount of functional corneal endothelial cells (CECs) is an urgent problem to be solved.Objective The aim of this study was to evaluate the role of aqueous humor on bovine CECs in vitro.Methods Aqueous humor of 1.2 ml was collected from the anterior chamber of bovine and sterilized,and the liquid supernatant was obtained.The bovine CECs were isolated from bovine cornea and then cultured in low glucose Dulbecco Modified Eagle Medium with 10% fetal bovine serum (FBS) in vitro.Aqueous humor was added into the medium with the final concentration of 2.5%,5.0%,l0.0%,15.0% and 20.0%,respectively,and no aqueous humor was added in the control group.Cell counting kit-8 (CCK-8) assay was used to detect the absorbency value of CECs for the evaluation of cell proliferation.Progression of the cell cycle was analyzed by flow cytometry (FCM).After confluence of the cells was reached,1 ml plastic spear tip was used to scratch the cell single layer,and the cells were incubated consequently in medium with 10% FBS and with or without aqueous humor for 24 hours.Healing area of the cell single layer was measured.The cells were incubated at a density of 6 × 105 cells/ml and cultured using medium with or without 10.0% aqueous human for 5 days,and the number of the cells was analyzed by DAPI fluorescence technique.Results Under the phase-contrast microscopy,the confluent CECs showed a slabstone-like and hexagonal appearance.CCK-8 assay revealed that the absorbance values of CECs was significantly different among the various culture groups (F=4.051,P =0.007),and the absorbance value in different concentrations of aqueous human culture groups was significantly higher than that in the control group (P < 0.01).FCM showed that the percentage of the cells in S-G2 phases was (34.80-±3.13)% in the 10.0% aqueous humors group and (23.06±1.13)

    Plant roots have the ability to produce and secrete substances, such as aliphatic low molecular weight organic acids (ALMWOAs), into the rhizosphere for several purposes, including in response to metal contamination. Despite this, little is yet known about the exudation of such substances from marsh plants roots in response to metal exposure. This work aimed at assessing the influence of the physiological cycle of marsh plants on the exudation of ALMWOAs in response to Cu contamination. In vitro experiments were carried out with Phragmites australis specimens, collected in different seasons. Plant roots were exposed to freshwater contaminated with two different Cu concentrations (67 μg/L and 6.9 mg/L), being the ALMWOAs released by the roots measured. Significant differences (both qualitative and quantitative) were observed during the Phragmites australis life cycle. At growing stage, Cu stimulated the exudation of oxalic and formic acids but no significant stimulation was observed for citric acid. At developing stage, exposure to Cu caused inhibition of oxalic acid exudation whereas citric acid liberation was stimulated but only in the media spiked with the lowest Cu concentration tested. At the decaying stage, no significant variation on oxalic acid was observed, whereas the citric and formic acids release increased as a consequence of the plant exposure to Cu. The physiological cycle of Phragmites australis, and probably also of other marsh plants, is therefore an important feature conditioning plants response to Cu contamination, in terms of ALMWOAs exudation. Hence this aspect should be considered when conducting studies on rhizodeposition involving marsh plants exposed to metals and in the event of using marsh plants for phytoremediation purposes in contaminated estuarine areas.

    Early studies on rodents showed that short-term exposure to high-intensity light (> 70 lx) above 600 nm (red-appearing) influences circadian neuroendocrine and metabolic physiology. Here we addressed the hypothesis that long-term, low-intensity red light exposure at night (rLEN) from a 'safelight' emitting no light below approximately 620 nm disrupts the nocturnal circadian melatonin signal as well as circadian rhythms in circulating metabolites, related regulatory hormones, and physi- ologic parameters. Male Sprague-Dawley rats (n = 12 per group) were maintained on control 12:12-h light:dark (300 lx; lights on, 0600) or experimental 12:12 rLEN (8.1 lx) lighting regimens. After 1 wk, rats underwent 6 low-volume blood draws via cardiocentesis (0400, 0800, 1200, 1600, 2000, and 2400) over a 4-wk period to assess arterial plasma melatonin, total fatty acid, glucose, lactic acid, pO2, pCO2, insulin, leptin and corticosterone concentrations. Results revealed plasma melatonin levels (mean ± 1 SD) were high in the dark phase (197.5 ± 4.6 pg/mL) and low in the light phase (2.6 ± 1.2 pg/mL) of control condi- tions and significantly lower than controls under experimental conditions throughout the 24-h period (P < 0.001). Prominent circadian rhythms of plasma levels of total fatty acid, glucose, lactic acid, pO2, pCO2, insulin, leptin, and corticosterone were significantly (P < 0.05) disrupted under experimental conditions as compared with the corresponding entrained rhythms under control conditions. Therefore, chronic use of low-intensity rLEN from a common safelight disrupts the circadian organization of neuroendocrine, metabolic, and physiologic parameters indicative of animal health and wellbeing.

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

    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.

  8. Identity and Stereotypes: Humor Manifestations

    Full Text Available The traditional understanding of humor as being tolerant, full of non-aggressive life curiosities, funny situations, mocking national or human vices, and related to an optimistic and contemplative attitude towards reality, has changed its main supportive points: the optimistic view of reality has been altered into a pessimistic and destructive one, forbearing ridicule has turned into severe offence, strangeness into stupidity, funny situations into futile misunderstanding. Everything is regarded as a dramatic possibility to survive or an endless situational tragedy where the most strict evaluation criteria, censorship, and dogmatism are empowered, meaning that, in the current times of widely propagated tolerance and overwhelming comprehension, it is extremely dangerous to offend somebody with an innocent joke or light mockery, to evoke an urge to contradict or negate when ideological aspirations are beyond “decency” limits. One of the most advocated rules in the Lithuanian press is: “Joke carefully with foreign nationals” from an interview with Barry Tomelin, London “International house” consultant and teaching director, the author of the book “World’s Business Cultures: And How to Unlock Them” (with Michael Nicks. Identity is to be saved and nourished as the highest sanctity but its formation, meaningfulness and spread are not always attuned to the official approach.Our life is full of stereotypes and our neighboring countries are not to be excluded – we have a preconceived notion of them. Using the national stereotype term we characterize relatively stable generalized opinions, in an open or hidden form, containing one or another assessment of a nation.Our attitude towards neighbors is revealed in nicknames given to them – non-official ethnonyms usually bearing a negative connotation.

    Full Text Available Environments shape health and well-being, yet little research has investigated how different real-world environmental settings influence the well-known determinant of health known as stress. Using a cross-over experimental design; this pilot study investigated the effect of four urban environments on physiological and psychological stress measures. Participants (N = 15 were exposed on separate days to one of the four settings for 20 min. These settings were designated as Very Natural; Mostly Natural; Mostly Built and Very Built. Visitation order to the four settings was individually randomized. Salivary cortisol and alpha-amylase; as well as self-report measures of stress; were collected before and after exposure to each setting. Gender was included as a variable in analysis; and additional data about environmental self-identity, pre-existing stress, and perceived restorativeness of settings were collected as measures of covariance. Differences between environmental settings showed greater benefit from exposure to natural settings relative to built settings; as measured by pre-to-post changes in salivary amylase and self-reported stress; differences were more significant for females than for males. Inclusion of covariates in a regression analysis demonstrated significant predictive value of perceived restorativeness on these stress measures, suggesting some potential level of mediation. These data suggest that exposure to natural environments may warrant further investigation as a health promotion method for reducing stress.

    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.

    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.

    Studies investigating the feasibility of new, or improved, biotechnologies, such as wastewater treatment digesters, inevitably start with laboratory-scale trials. However, it is rarely determined whether laboratory-scale results reflect full-scale performance or microbial ecology. The Expanded Granular Sludge Bed (EGSB) bioreactor, which is a high-rate anaerobic digester configuration, was used as a model to address that knowledge gap in this study. Two laboratory-scale idealizations of the EGSB-a one-dimensional and a three- dimensional scale-down of a full-scale design-were built and operated in triplicate under near-identical conditions to a full-scale EGSB. The laboratory-scale bioreactors were seeded using biomass obtained from the full-scale bioreactor, and, spent water from the distillation of whisky from maize was applied as substrate at both scales. Over 70 days, bioreactor performance, microbial ecology, and microbial community physiology were monitored at various depths in the sludge-beds using 16S rRNA gene sequencing (V4 region), specific methanogenic activity (SMA) assays, and a range of physical and chemical monitoring methods. SMA assays indicated dominance of the hydrogenotrophic pathway at full-scale whilst a more balanced activity profile developed during the laboratory-scale trials. At each scale, Methanobacterium was the dominant methanogenic genus present. Bioreactor performance overall was better at laboratory-scale than full-scale. We observed that bioreactor design at laboratory-scale significantly influenced spatial distribution of microbial community physiology and taxonomy in the bioreactor sludge-bed, with 1-D bioreactor types promoting stratification of each. In the 1-D laboratory bioreactors, increased abundance of Firmicutes was associated with both granule position in the sludge bed and increased activity against acetate and ethanol as substrates. We further observed that stratification in the sludge-bed in 1-D laboratory

    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).

    Aqueous humor production is a metabolically active process sustained by the delivery of oxygen and nutrients and removal of metabolic waste by the ciliary circulation. This article describes our investigations into the relationship between ciliary blood flow and aqueous humor production. The results presented indicate that there is a dynamic relationship between ciliary blood flow and aqueous humor production, with production being blood flow independent above a critical level of perfusion, and blood flow dependent below it. The results also show that the plateau portion of the relationship shifts up or down depending on the level of secretory stimulation or inhibition, and that oxygen is one critical factor provided by ciliary blood flow. Also presented is a theoretical model of ocular hydrodynamics incorporating these new findings. PMID:20801226

    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.

    The infusion of humor in the classroom through faculty-developed skits is a teaching-learning strategy that engages nursing students in the learning process. Gardner's Multiple Intelligence Theory for Adult Learners provides the framework for the use of humor as a strategy in higher education. Three exemplars are presented with a description of the specific strategy, an objective for each strategy, and the effect of the strategy on student engagement in nursing education. In the exemplars, the authors provide "ready to use" ideas with some "pearls of wisdom" for other faculty interested in developing similar learning activities.

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

    Directory of Open Access Journals (Sweden)

    Fay Caroline Mary Geisler

    2014-08-01

    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.

    Wilbur, Christopher J; Campbell, Lorne

    2011-07-01

    Several lines of research illustrate that humor plays a pivotal role in relationship initiation. The current article applies sexual selection theory to argue that humor production is a fitness indicator, allowing men to transmit information tacitly about their underlying qualities. And whereas prior research has emphasized women's appreciation of humor as a signal of interest, the focus here is on how women evaluate prospective suitors' humorous offerings. Two studies, including an ecologically valid study of online dating advertisements, provided evidence for men's production and women's evaluation of humor in romantic contexts. A third study revealed that women's evaluations of potential mates' humor are predictive of their romantic interest. Moreover, this article shows that preferences for and perceptions of humor are associated with preferences for and perceptions of intelligence and warmth, consistent with the argument that one function of humor is as a fitness indicator that provides information about underlying mate quality.

    Various toxicants have previously been held responsible for an impaired capacity of fish from polluted environments to elevate their cortisol levels in response to stress. In the present study we investigated the responses to stress in o'p-DDD [2-(chlorophenyl)-2-(4-chlorphenyl)-1,1-dichloroethane] exposed (given a single, oral dose of 75 mg o'p-DDD/kg fish) and unexposed Arctic charr. After o'p-DDD administration fish were left undisturbed and without being fed for 28 days, when they were subjected to an acute handling stress. At 1, 3, 7 and 23 h following stress, primary (ACTH and cortisol secretion) and secondary (plasma Cl levels and energy mobilisation) components of the stress response were monitored. As the nutritional state of wild fish may influence this potential biomarker response, the fish had been subjected to a restricted feed ration prior to o'p-DDD administration in order to obtain marked within-group variations in condition factor. No effects of o'p-DDD were observed on post-stress hormone secretion (i.e. peak post-stress plasma ACTH and cortisol levels), nor on plasma chloride levels. However, other results obtained provided evidence for a metabolic depression by o'p-DDD, witnessed by consistently lower plasma glucose levels before and after stress in these contaminated fish. This may be related to the finding that during the 30-day period between o'p-DDD administration and stress treatment, toxicant treated fish lost less weight in comparison to their sham-treated counterparts. Nutritional state did not appear to influence the performance of the charr in the present experiment, as correlations between the parameters measured and condition factor or lipid contents on an individual basis in all cases turned out non significant. Overall, the results contrast with those of previous in vivo and in vitro studies on fish, which concluded that comparable headkidney o'p-DDD levels impaired interrenal steroidogenesis. Although we conclude that the effects

    Full Text Available The author of this article suggests a diachronic approach to the humorous mode and criticizes any essentialist theory that defines the concept as a closed category. Every kind of humour within the whole spectrum, i.e. satire and irony, should be looked at following semantic and pragmatic principles, not forgetting the influence of classical rhetoric. As regards the recent history of Spanish humour, the contributions of the most important authors of the so-called «otra generación del 27» shall be analyzed by considering the reasons for their ostracism and for the lack of a present high quality generation of authors able to take over their literary tradition.El autor de este artículo propone un acercamiento diacrónico a la modalidad humorística, y crítica cualquier aproximación de carácter esencialista que trate de fijar el concepto como una categoría cerrada. Cada una de las especies del espectro humorístico —la sátira y la ironía, por ejemplo— debieran abordarse desde una óptica que combine la semántica con la pragmática, sin olvidar el concurso de la antigua retórica. En cuanto a la historia más reciente del humorismo hispano, se valoran los autores más representativos de la llamada «otra generación del 27», reflexionando sobre la causa de su postergación y sobre la ausencia en la actualidad de un relevo de verdadera calidad literaria.

    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.

    Full Text Available Not all humor is the same, yet little is known about the appeal of specific humor styles in romantic initiation. 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.

  7. Vaccination to gain humoral immune memory.

    2016-12-01

    The concept of immune memory forms the biological basis for vaccination programs. Despite advancements in the field of immune memory and vaccination, most current vaccines are evaluated by magnitude of antigen-specific antibody titers in serum or mucosa after vaccination. It has been shown, however, that antibody-mediated humoral immune memory is established regardless of the magnitude and duration of immune reactions, suggesting that assessment of vaccine efficacy should be performed for several years after vaccination. This long-term investigation is disadvantageous for prevalent and pandemic infections. Long-lived memory plasma cells and memory helper T cells which contribute to humoral immune memory are generated in the bone marrow after migration of memory cell precursors through bloodstream. Thus, it may be a novel evaluation strategy to assess the precursors of memory cells in the blood in the early phase of the immune reaction(s). We here review recent advances on the generation and maintenance of immune memory cells involved in humoral immunity and introduce a current concept of direct and short-term assessment of humoral immune memory formation upon vaccination as a correlate of protection.

    2011-12-01

    Full Text Available “Dialogue”, in Bakhtin’s thought, is a term which has a methodological nature. This term shows a method for facing cases which are not hegemonic. Dialogue, therefore, is in opposition to the hegemony of monophonic forces. The origins of the dialogical aspects of humor, laugh and carnival are in very character. In this article, we want to investigate the bases that make the dialogical carnival and form the humorous elements. In the first section, we illustrate the subversion of the superior voice as a semantic and formal structural method in Mathnavi. In the second section, the reflection of this method in formation of humor in the stories of Mathnavi has been investigated. In these stories, presence of the superior voice in the public space and its dialogue with the suppressed voices makes a space steeped in the elements of carnival and laugh. It can be said that the humors in Mathnavi are not the techniques for embellishing the text but the affects of the transcendental method of Mathnavi for interpreting the world.

  15. Anomalous hypothalamic responses to humor in cataplexy.

    Directory of Open Access Journals (Sweden)

    Allan L Reiss

    Full Text Available BACKGROUND: 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. METHODOLOGY/PRINCIPAL FINDINGS: 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. CONCLUSIONS: 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.

    GM (γ marker) allotypes, genetic variants of immunoglobulin γ chains, have been reported to be associated strongly with susceptibility to lung cancer, but the mechanism(s) underlying this association is not known. One mechanism could involve their contribution to humoral immunity to lung tumour-associated antigens. In this study, we aimed to determine whether particular GM and KM (κ marker) allotypes were associated with antibody responsiveness to XAGE-1b, a highly immunogenic lung tumour-associated cancer-testis antigen. Sera from 89 patients with non-small cell lung cancer (NSCLC) were allotyped for eight GM and two KM determinants and characterized for antibodies to a synthetic XAGE-1b protein. The distribution of various GM phenotypes was significantly different between XAGE-1b antibody-positive and -negative patients (P = 0·023), as well as in the subgroup of XAGE-1b antigen-positive advanced NSCLC (P = 0·007). None of the patients with the GM 1,17 21 phenotype was positive for the XAGE-1b antibody. In patients with antigen-positive advanced disease, the prevalence of GM 1,2,17 21 was significantly higher in the antibody-positive group than in those who lacked the XAGE-1b antibody (P = 0·026). This phenotype also interacted with a particular KM phenotype: subjects with GM 1,2,17 21 and KM 3,3 phenotypes were almost four times (odds ratio = 3·8) as likely to be positive for the XAGE-1b antibody as the subjects who lacked these phenotypes. This is the first report presenting evidence for the involvement of immunoglobulin allotypes in immunity to a cancer-testis antigen, which has important implications for XAGE-1b-based immunotherapeutic interventions in lung adenocarcinoma.

  17. Influence of Prior Intense Exercise and Cold Water Immersion in Recovery for Performance and Physiological Response during Subsequent Exercise.

    Christensen, Peter M; Bangsbo, Jens

    2016-01-01

    Athletes in intense endurance sports (e.g., 4000-m track cycling) often perform maximally (~4 min) twice a day due to qualifying and finals being placed on the same day. The purpose of the present study was to evaluate repeated performance on the same day in a competitive setting (part A) and the influence from prior intense exercise on subsequent performance and physiological response to moderate and maximal exercise with and without the use of cold water immersion (CWI) in recovery (part B). In part A, performance times during eight World championships for male track cyclists were extracted from the qualifying and final races in 4000-m individual pursuit. In part B, twelve trained cyclists with an average (±SD) ⩒O2-peak of 67 ± 5 mL/min/kg performed a protocol mimicking a qualifying race (QUAL) followed 3 h later by a performance test (PT) with each exercise period encompassing intense exercise for ~4 min preceded by an identical warm-up period in both a control setting (CON) and using cold water immersion in recovery (CWI; 15 min at 15°C). Performance was lowered (P < 0.001) from qualification to finals (259 ± 3 vs. 261 ± 3 s) for the track cyclists during World championships in part A. In part B, mean power in PT was not different in CWI relative to CON (406 ± 43 vs. 405 ± 38 W). Peak ⩒O2 (5.04 ± 0.50 vs. 5.00 ± 0.49 L/min) and blood lactate (13 ± 3 vs. 14 ± 3 mmol/L) did not differ between QUAL and PT and cycling economy and potassium handling was not impaired by prior intense exercise. In conclusion, performance is reduced with repeated maximal exercise in world-class track cyclists during 4000-m individual pursuit lasting ~4 min, however prior intense exercise do not appear to impair peak ⩒O2, peak lactate, cycling economy, or potassium handling in trained cyclists and CWI in recovery does not improve subsequent performance.

    Lin Yutang is called the master humorist in China. He advocates humor and spiritual literature in his maga-zine Lun Yu (Analects) which attracts essays and readership. His informal but polished style in both Chinese and English makes him one of the most influential writers of his generation, and his compilations and translations of classic Chinese texts into English are bestsellers in the West. Humor is a distinctive feature in his works. In his book, he uses humor as he sees appropriate, and through humor he criticizes social realities, depicts characters and introduces original expressions, etc. His humor can be related to some aspects in his life. In this paper, I will briefly analysis Lin's sense of humor and how Lin' applies humor in his works.

  4. Differentiating what is humorous from what is not.

    2016-03-01

    After 2.5 millennia of philosophical deliberation and psychological experimentation, most scholars have concluded that humor arises from incongruity. We highlight 2 limitations of incongruity theories of humor. First, incongruity is not consistently defined. The literature describes incongruity in at least 4 ways: surprise, juxtaposition, atypicality, and a violation. Second, regardless of definition, incongruity alone does not adequately differentiate humorous from nonhumorous experiences. We suggest revising incongruity theory by proposing that humor arises from a benign violation: something that threatens a person's well-being, identity, or normative belief structure but that simultaneously seems okay. Six studies, which use entertainment, consumer products, and social interaction as stimuli, reveal that the benign violation hypothesis better differentiates humorous from nonhumorous experiences than common conceptualizations of incongruity. A benign violation conceptualization of humor improves accuracy by reducing the likelihood that joyous, amazing, and tragic situations are inaccurately predicted to be humorous.

    The ocular barriers (cornea, blood-retinal barrier, and blood-aqueous humor barrier) make treating eye diseases with therapeutic drugs challenging. The tight capillary endothelium of the iris and the ciliary body epithelium form the blood-aqueous humor barrier. The iris and ciliary body (iris-ciliary body) express a variety of drug transporters in the ATP-binding cassette and solute carrier (SLC) families. ATP-binding cassette family drug transporters that are present in the iris-ciliary body include P-glycoprotein, breast cancer resistance protein, and several multidrug resistance-associated proteins. SLC family drug transporters that are present in the iris-ciliary body include organic anion transporters, organic anion transporting polypeptides, bile acid transporters (apical sodium-dependent bile salt transporter and sodium taurocholate cotransporter), organic cation transporters (novel organic cation transporter and multidrug and toxin extrusion transporter) and peptide transporters. Freshly dissected iris-ciliary body preparations actively accumulate a variety of substrates of SLC drug transporters that are expressed in the tissue. The ciliary body in vitro supports active transport in the aqueous humor-to-blood direction of several substrates of organic anion transporters and multidrug resistance-associated proteins, consistent with the subcellular localization of these transporters in the ciliary body epithelium. In vivo data suggest that drug transporters in the iris-ciliary body reduce the permeation of drugs in the direction of blood-to-aqueous humor, thereby reducing ocular drug bioavailability, and are also involved in active drug elimination from the aqueous humor. An understanding of the influence on pharmacokinetics of drug transporters in the blood-aqueous humor barrier should help improve drug delivery and efficacy in the eye.

  7. 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.

    The effect of male accessory gland substances on female reproductive physiology has been previously described as "activating" egg development. However, no mechanism has been described that can explain how male mosquitoes are able to influence egg development in female mosquitoes. To investigate how male mosquitoes are able to influence ovarian physiology and reproductive output we explored three main questions: (1) Do mating and male accessory gland substances affect ovarian physiology and alter markers of oocyte quality during the previtellogenic resting stage? (2) Does the male accessory gland contain JH III and is JH III transferred to the female during copulation? (3) Finally, does the nutritional history of the male affect the amount of JH III transferred to the female and alter reproductive output? By answering these questions it is clear that male mosquitoes are able to alter the female's resource allocation priorities towards reproduction by transferring JH III during copulation; reducing the rate of previtellogenic resorption and increasing the amount of stored ovarian lipids. These changes improve an individual follicle's likelihood of development after a blood meal. In addition, males maintained under better nutritional conditions make and transfer more JH III, prevent more follicular resorption and realize higher fecundities than other males. Together these results illustrate one mechanism behind the "activating" effect of mating described as well as the role sugar feeding plays in male mosquitoes. Copyright © 2014 Elsevier Ltd.

    Full Text Available El humor es un fenómeno poco estudiado dentro del contexto de la psicología, menos aún, en el adulto mayor, grupo etario que se encuentra en constante crecimiento dentro de nuestro país.En tal sentido, la investigación, guiada por los planteamientos de Carbelo (2007 y DAnello (2010, denominada sentido del humor en el adulto mayor, tuvo por objetivo, determinar el significado que tiene este fenómeno para el adulto mayor. Para ello, se realizó un estudio de corte cualitativo,donde se utilizó la Entrevista en Profundidad como método de recolección de la información. Los informantes fueron 4 adultos mayores (2 hombres y 2 mujeres con edades comprendidas entre 60 y 73 años de edad, los cuales fueron seleccionados como una muestra de propósito. Para el análisis, se utilizó la Teoría Fundamentada, concluyéndose que para el adulto mayor, cuando el sentido del humor se convierte en parte de la personalidad, es un factor protector de la salud, da sentido de pertenencia y cambia positivamente el ambiente, trayendo como consecuencia una mejor calidad de vida, siendo esto último el principal significante que surgió del análisis de la información. Igualmente, se determinó que el sentido del humor es una construcción social que se va elaborando a lo largo de la vida y que se afianza en esta etapa vital.

    Full Text Available Tuberculous pleuritis is a good human model to understand the local and protective immune response against tuberculosis, due to the self-limitedness of the disease. Although the cellular immune response has been well characterised in tuberculous pleurisy, much less is known about the humoral immune response operating at the site of infection. To understand the humoral immune response, B cells were enumerated in peripheral blood mononuclear cells (PBMC and pleural fluid mononuclear cells (PFMC of tuberculous (TP and non-tuberculous pleuritis patients (NTP. The levels of IgG, IgA and IgM antibodies for PPD, culture filtrate (CF and sonicate antigens (Son Ag were assessed in plasma (BL and pleural fluid (PF and a western blot was carried out with the CF antigen. The percentage of CD19+B-cells was similar in PBMC and PFMC of TP patients but was significantly lower in PFMCs of NTP patients. The IgG levels for PPD and CF antigens were higher in PF of TP than NTP patients. The antigen recognition patterns did not differ in plasma and pleural fluid of the same patient in both groups pointing out the passive diffusion of the plasma to the pleura. The antigens 25, 31, 33, 70, 110, 124 and 132 kDa were recognized exclusively by the TP patients. Thus our study showed that the local humoral response in TP did not differ from the systemic response. However, the humoral response differed in TP patients when compared to NTP patients.

  16. 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.

    Full Text Available Humor is defined as a state of good spirit, exhibited with a smile or laughter, as a response to external stimuli. It constitutes a special form of human communication as well as a form of social conduct. The word «humor» appears for the first time in Hippocrates' writings. Psychology considers humor as one of the most powerful weapons against depression and disappointment. In psychiatric therapeutics humor serves many purposes, thereby acting as a supplement, not a substitute to treatment received. Purpose: of this article is to highlight the positive effects of humor in humans, health professionals and patient. Material and method: An extensive literature search databases such as Medline, Pub Med, Wikipedia, Cinahl, Medscape, with key words: humor, psychiatric patient, care, humor scales Results: Humor is an interpersonal process which facilitates and promotes expression and exchange of views; however it requires prudence, cautiousness and respect to patients' personality and sensitive issues. Humor is not innate, it is acquired and it can be learning and taught. Conclusion: The correct use of humor in therapeutic practice, contributes to the development of a therapeutic relationship between patient and healthcare professional as well as a sense of trust between them.

  18. 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

    Knowledge of the many physiological factors associated with egg production , fertility, incubation, and brooding in nondomestic birds is limited. Science knows even less about reproduction in most of the 238 endangered or threatened birds. This discussion uses studies of nondomestic and, when necessary, domestic birds to describe physiological control of reproduction. Studies of the few nondomestic avian species show large variation in physiological control of reproduction. Aviculturists, in order to successfully propagate an endangered bird, must understand the bird's reproductive peculiarities. First, investigators can do studies with carefully chosen surrogate species, but eventually they need to confirm the results in the target endangered bird. Studies of reproduction in nondomestic birds increased in the last decade. Still, scientists need to do more comparative studies to understand the mechanisms that control reproduction in birds. New technologies are making it possible to study reproductive physiology of nondomestic species in less limiting ways. These technologies include telemetry to collect information without inducing stress on captives (Howey et al., 1987; Klugman, 1987), new tests for most of the humoral factors associated with reproduction, and the skill to collect small samples and manipulate birds without disrupting the physiological mechanisms (Bercovitz et al., 1985). Managers are using knowledge from these studies to improve propagation in zoological parks, private and public propagation facilities, and research institutions. Researchers need to study the control of ovulation, egg formation, and oviposition in the species of nondomestic birds that lay very few eggs in a season, hold eggs in the oviduct for longer intervals, or differ in other ways from the more thoroughly studied domestic birds. Other techniques that would enhance propagation for nondomestlc birds include tissue culture of cloned embryonic cells, cryopreservation of embryos

    Throughout tomato domestication, a large increase in fruit size was associated with a loss of dry matter and sugar contents. This study aims to dissect the contributions of genetic variation and the physiological processes underlying the relationships between fruit growth and the accumulation of dry matter and sugars. Fruit quality traits and physiological parameters were measured on 20 introgression lines derived from the introgression of Solanum chmielewskii into S. lycopersicum, under high (HL, unpruned trusses) and low (LL, trusses pruned to one fruit) fruit load conditions. Inter- and intra-genotypic correlations among traits were estimated and quantitative trait loci (QTL) for size, composition, and physiological traits were mapped. LL increased almost all traits, but the response of sugar content was genotype-dependent, involving either dilution effects or differences in carbon allocation to sugars. Genotype x fruit load interactions were significant for most traits and only 30% of the QTL were stable under both fruit loads. Many QTL for fresh weight and cell or seed numbers co-localized. Eleven clusters of QTL for fresh weight and dry matter or sugar content were detected, eight with opposite allele effects and three with negative effects. Two genotypic antagonistic relationships, between fresh weight and dry matter content and between cell number and cell size, were significant only under HL; the second could be interpreted as a competition for carbohydrates among cells. The role of cuticular conductance, fruit transpiration or cracking in the relationship between fruit fresh weight and composition was also emphasized at the genetic and physiological levels.

    1984-01-01

    Although humor and laughter have been a natural part of human life in all cultures as far back as recorded history can determine, the conscious use of humor as a therapeutic technique is comparatively recent. This article suggests that health specialists have been slow to adopt the ideas of some of the better known researchers and writers in the field due to professional and cultural attitudes toward humor as a "frivolous" subject. As more information on the positive benefits of humor and laughter is being disseminated in books and workshops, previous myths regarding humor are being dispelled and attitudes are changing. A brief history of the state of the art over the past decade is included along with a few ideas from seminars and workshops on the use of humor as a planned activity in health and educational settings.

    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.

    2006-09-01

    Laughter, the physical response to perceived humor, has demonstrated positive effects on physical and psychological well-being. Studies that focus on effects of humor on health and well-being of older adults are scarce. No studies were found that examine what older adults find humorous. The purpose of this descriptive study was to explore the humor stimulus in a population of older adults. One hundred thirty (130) hospital auxiliary personnel aged 50 and older were asked the question What makes you laugh? Content analysis of responses revealed nine themes in two major categories, which were (a) people or animals and (b) situations or events. Children represented the largest category of people (30%), and telling jokes represented the largest category of situations or events (51%). Humor can be used by nurses as an effective therapeutic tool when caring for older adults if appropriate sources of humor are identified and applied.

However, it is not applicable to all. If not used properly, the humor inthe advertisements may have reversed influence. This research attempted to find out which types of merchandise humor was more applicable, using Product Color Matrix as the standard classification for merchandises. I chose two kinds of representative merchandise from each category, which were big tools (range hood, water heater), big toys (diamond bracelet, sports car), little treats (beer, juice), and little tools (toothpaste and beer bottle opener). Two different print advertisements were made for each merchandise, respectively, humorous ad and non-humorous ad. Two hypotheses were put forward : ( 1 ) humor always harvested good advertising effect ; ( 2 ) humor acted dif- ferently on the merchandise of different types. A total of 16 adapted unfamiliar or foreign print advertisements were shown to 160 college students, who were randomly selected to take the questionnaire. In this experiment with balanced design, univariate analysis variance and multivariate analysis of variance were applied to analyze data. Whether humor was used in advertisement was the independent variable. Evaluation and the order of the ads were the covariates. Impression, preference, and purchase intention toward the merchandise were the dependent variables

    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.

    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.

    Humor, a distinctive linguistic phenomenon, plays an important role in the language culture. In addition, humor has become a topic in linguistics. As the most important principles in pragmatics, the CP has provided a theoretical tool for analyzing humor, which is the product of the speaker’s intentional or unintentional violation of certain maxim of the Cooperative Principle. Participants should understand the literal meaning of an utterance firstly, and then, by relating the utterance to the specific context and certain background information, they come to realize the violation of the CP and appreciate the humor.

    What is believed to be the most important thing in translating English movie subtitle is the transmission of humorous effects. Humor is the development result of language and culture, and it is human's wisdom. Based on Vermeer's Skopostheorie theory of functionalist approaches, the thesis suggests that the instrumental translation strategy based on the source text analysis can be used for the translation of humor discourses. The translator can translate humorous languages by way of literal translation, annotation, combination of literal translation and free translation.

    Repeated anaesthesia may be required in experimental protocols and in daily veterinary practice, but anaesthesia is known to alter physiological parameters in GPs (Cavia porcellus, GPs). This study investigated the effects of repeated anaesthesia with either medetomidine-midazolam-fentanyl (MMF) or isoflurane (Iso) on physiological parameters in the GP. Twelve GPs were repeatedly administered with MMF or Iso in two anaesthesia sets. One set consisted of six 40-min anaesthesias, performed over 3 weeks (2 per week); the anaesthetic used first was randomized. Prior to Iso anaesthesia, atropine was injected. MMF anaesthesia was antagonized with AFN (atipamezole-flumazenil-naloxone). Abdominally implanted radio-telemetry devices recorded the mean arterial blood pressure (MAP), heart rate (HR) and core body temperature continuously. Additionally, respiratory rate, blood glucose and body weight were assessed. An operable state could be achieved and maintained for 40 min in all GPs. During the surgical tolerance with MMF, the GPs showed a large MAP range between the individuals. In the MMF wake- up phase, the time was shortened until the righting reflex (RR) returned and that occurred at lower MAP and HR values. Repeated Iso anaesthesia led to an increasing HR during induction (anaesthesias 2–6), non-surgical tolerance (anaesthesias 3–6) and surgical tolerance (anaesthesias 4, 6). Both anaesthetics may be used repeatedly, as repeating the anaesthesias resulted in only slightly different physiological parameters, compared to those seen with single anaesthesias. The regular atropine premedication induced HR increases and repeated MMF anaesthesia resulted in a metabolism increase which led to the faster return of RR. Nevertheless, Iso’s anaesthesia effects of strong respiratory depression and severe hypotension remained. Based on this increased anaesthesia risk with Iso, MMF anaesthesia is preferable for repeated use in GPs. PMID:28328950

    Physical fitness training of military recruits is an enduring focus of armies. This is important for safe and effective performance of general tasks that anyone may have to perform in a military setting as well as preparation for more specialized training in specific job specialties. Decades of studies on occupationally specific physical requirements have characterized the dual aerobic and strength demands of typical military tasks; however, scientifically founded strategies to prepare recruits with a good mix of these 2 physiologically opposing capabilities have not been well established. High levels of aerobic training can compromise resistance training gains and increase injury rates. Resistance training requires a greater commitment of time and resources as well as a greater understanding of the science to produce true strength gains that may be beneficial to military performance. These are critical issues for modern armies with increased demands for well-prepared soldiers and fewer injury losses. The actual physical requirements tied to metrics of success in military jobs are also under renewed examination as women are increasingly integrated into military jobs previously performed only by men. At the third International Congress on Soldiers' Physical Performance, a roundtable of 10 physiologists with military expertise presented comparative perspectives on aerobic and strength training. These topics included the physiological basis of training benefits, how to train effectively, how to measure training effectiveness, considerations for the integration of women, and the big perspective. Key discussion points centered on (a) the significance of findings from research on integrated training, (b) strategies for effective strength development, and

    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.

    Full Text Available This study has been carried out to determine the death interval from the biochemical parameter of vitreous potassium. In 308 medicolegal cases vitreous humor was taken and analyzed for potassium with known time of death. There was a linear rise in potassium concentration with increasing death interval. Regression equation was calculated for the same. The study indicates that potassium levels in vitreous for determining death interval are useful and can afford a good method of determining the death interval along with other traditional methods. Also the previously established formulae for estimating death interval from vitreous potassium were also studied.

    Endothelin-1 (ET-1) has been found in elevated concentrations in the aqueous humor of glaucoma patients. Indirect evidence from animal studies suggests that ET-1 might directly influence intraocular pressure (IOP). The aim of this study was to determine whether ET-1 concentrations in aqueous humor of cataract and glaucoma patients correlate with IOP. Aqueous humor and blood samples from patients with either cataract (control, n = 38), primary open angle glaucoma (POAG, n = 35), or pseudoexfoliation glaucoma (PEXG, n = 21), without other ocular or systemic disease, were collected during routine cataract surgery or trabeculectomy. ET-1 concentration was determined by an ET-1 ELISA kit. IOP was measured preoperatively by standard Goldmann applanation tonometry. All statistical analysis was performed using commercial predictive analytics software. Both IOP and ET-1 concentration in aqueous humor were significantly increased in POAG (23.4 ± 6.8 mm Hg, 5.9 ± 2.9 pg/mL) and PEXG (24.3 ± 8.8 mm Hg, 7.7 ± 2.1 pg/mL) compared with control (15.0 ± 2.9 mm Hg, 4.3 ± 2.4 pg/mL). No difference was detected for plasma ET-1 concentrations. IOP and ET-1 in the aqueous humor were significantly correlated (R = 0.394, R² = 0.155, P < 0.001), although no correlation was found between IOP and ET-1 in blood plasma or between ET-1 in aqueous humor and ET-1 in plasma. In this study, a small but highly significant correlation between IOP and the ET-1 concentration in the aqueous humor was found. Although no causative relationship can be deduced from this, ocular ET-1 effects on IOP control may merit further investigation.

  4. Competitive fitness during feast and famine: how SOS DNA polymerases influence physiology and evolution in Escherichia coli.

    2013-06-01

    Escherichia coli DNA polymerases (Pol) II, IV, and V serve dual roles by facilitating efficient translesion DNA synthesis while simultaneously introducing genetic variation that can promote adaptive evolution. Here we show that these alternative polymerases are induced as cells transition from exponential to long-term stationary-phase growth in the absence of induction of the SOS regulon by external agents that damage DNA. By monitoring the relative fitness of isogenic mutant strains expressing only one alternative polymerase over time, spanning hours to weeks, we establish distinct growth phase-dependent hierarchies of polymerase mutant strain competitiveness. Pol II confers a significant physiological advantage by facilitating efficient replication and creating genetic diversity during periods of rapid growth. Pol IV and Pol V make the largest contributions to evolutionary fitness during long-term stationary phase. Consistent with their roles providing both a physiological and an adaptive advantage during stationary phase, the expression patterns of all three SOS polymerases change during the transition from log phase to long-term stationary phase. Compared to the alternative polymerases, Pol III transcription dominates during mid-exponential phase; however, its abundance decreases to <20% during long-term stationary phase. Pol IV transcription dominates as cells transition out of exponential phase into stationary phase and a burst of Pol V transcription is observed as cells transition from death phase to long-term stationary phase. These changes in alternative DNA polymerase transcription occur in the absence of SOS induction by exogenous agents and indicate that cell populations require appropriate expression of all three alternative DNA polymerases during exponential, stationary, and long-term stationary phases to attain optimal fitness and undergo adaptive evolution.

    Soil organic matter plays a major role in determining the fate of the engineered nanomaterials (ENMs) in the soil matrix and effects on the residing plants. In this study, kidney bean plants were grown in soils varying in organic matter content and amended with 0-500mg/kg cerium oxide nanoparticles (nano-CeO2) under greenhouse condition. After 52days of exposure, cerium accumulation in tissues, plant growth and physiological parameters including photosynthetic pigments (chlorophylls and carotenoids), net photosynthesis rate, transpiration rate, and stomatal conductance were recorded. Additionally, catalase and ascorbate peroxidase activities were measured to evaluate oxidative stress in the tissues. The translocation factor of cerium in the nano-CeO2 exposed plants grown in organic matter enriched soil (OMES) was twice as the plants grown in low organic matter soil (LOMS). Although the leaf cover area increased by 65-111% with increasing nano-CeO2 concentration in LOMS, the effect on the physiological processes were inconsequential. In OMES leaves, exposure to 62.5-250mg/kg nano-CeO2 led to an enhancement in the transpiration rate and stomatal conductance, but to a simultaneous decrease in carotenoid contents by 25-28%. Chlorophyll a in the OMES leaves also decreased by 27 and 18% on exposure to 125 and 250mg/kg nano-CeO2. In addition, catalase activity increased in LOMS stems, and ascorbate peroxidase increased in OMES leaves of nano-CeO2 exposed plants, with respect to control. Thus, this study provides clear evidence that the properties of the complex soil matrix play decisive roles in determining the fate, bioavailability, and biological transport of ENMs in the environment.

  6. Climate influences thermal balance and water use in African and Asian elephants: physiology can predict drivers of elephant distribution.

    Elephant movement patterns in relation to surface water demonstrate that they are a water-dependent species. Thus, there has been interest in using surface water management to mitigate problems associated with localized elephant overabundance. However, the physiological mechanisms underlying the elephant's water dependence remain unclear. Although thermoregulation is likely an important driver, the relationship between thermoregulation, water use and climate has not been quantified. We measured skin surface temperature of and cutaneous water loss from 13 elephants (seven African, 3768±642 kg; six Asian, 3834±498 kg) and determined the contribution of evaporative cooling to their thermal and water budgets across a range of air temperatures (8-33°C). We also measured respiratory evaporative water loss and resting metabolic heat production on a subset of elephants (N=7). The rate of cutaneous evaporative water loss ranged between 0.31 and 8.9 g min(-1) m(-2) for Asian elephants and 0.26 and 6.5 g min(-1) m(-2) for African elephants. Simulated thermal and water budgets using climate data from Port Elizabeth, South Africa, and Okaukuejo, Namibia, suggested that the 24-h evaporative cooling water debt incurred in warm climates can be more than 4.5 times that incurred in mesic climates. This study confirms elephants are obligate evaporative coolers but suggests that classification of elephants as water dependent is insufficient given the importance of climate in determining the magnitude of this dependence. These data highlight the potential for a physiological modeling approach to predicting the utility of surface water management for specific populations.

    In the context of global warming and given recent heat waves observed in Western Europe, the relationship between the soil water status and the plant health has recently received more attention, especially for cash crops like chicory. In this study we particularly investigated the impact of soil water status on the chicory root water uptake and density and made a link with physiological and yield parameters. During five months, we imposed different irrigation levels to 10 plants of chicory (Cichorium intybus var. sativum) growing in greenhouses. Each seed, coming from an autogamous selection in this allogamous species, was sown in a column of 1.42m height and 0.4m diameter filled with yellow sand and irrigated from the bottom with Hoagland solution. On those 10 columns, we measured the distribution of soil moisture with TDR (8 columns) and ERT (2 columns) probes. Lateral windows also allowed us to follow the root growth. The column weights were also monitored in order to quantify the plant transpiration. During the experiment, several physiological indices were also followed like the gas exchange (CO2 and transpiration), the chlorophyll fluorescence, the stomatal conductance, the plastochron, and the Leaf Area Index (LAI). At the end of the experiment, the complete root length density and the water content profiles were measured. We had also a look to the osmotic potential, the pigments content and the isotopic discrimination of carbon in the leaves, which gives information about the level of stress. At a biochemical point of view, we measured the content in enzymes involves in inulin metabolism and sugars synthesis. We observed that the plants suffering from a slight water stress developed better. A simple1-D model was built which describes the root growth in function of the irrigation level and of the soil and atmospheric boundary conditions.

  15. Laugh yourself to sleep: memory consolidation for humorous information.

    Chambers, Alexis M; Payne, Jessica D

    2014-05-01

    There is extensive evidence that emotional information is better remembered than neutral information across long delays, especially if the delay interval contains an opportunity for sleep. However, as prior studies have focused on memory for negative stimuli, it is unclear whether positive memories benefit from time and sleep as well. To investigate the consolidation of positive memories, the current study examined differences in memory for humorous and non-humorous cartoons. While prior evidence demonstrates that humorous information is preferentially remembered relative to non-humorous information over brief delays, it is unknown whether this benefit lasts across longer delay intervals or whether sleep is important for lasting humor memories to form. Thus, we tested memory for 27 cartoons across 12-h delay periods containing either sleep or wakefulness. Results indicate that humor's enhancing effect on recall memory is robust across a 12-h delay and that a period of sleep facilitates this effect over wakefulness when cartoons are novel to participants and ranked based on subjective emotional ratings. Further, in accordance with previous studies that reveal diminished emotional reactivity to stimuli following sleep, in a supplemental experiment, we found that sleep reduced subjective ratings of humor, arousal, and positivity of humorous cartoons. These findings provide preliminary evidence that sleep's impact on negative emotional memory consolidation and emotional reactivity can be extended to positive stimuli as well.

  16. Influence of Physiological Gastrointestinal Surfactant Ratio on the Equilibrium Solubility of BCS Class II Drugs Investigated Using a Four Component Mixture Design.

    The absorption of poorly water-soluble drugs is influenced by the luminal gastrointestinal fluid content and composition, which control solubility. Simulated intestinal fluids have been introduced into dissolution testing including endogenous amphiphiles and digested lipids at physiological levels; however, in vivo individual variation exists in the concentrations of these components, which will alter drug absorption through an effect on solubility. The use of a factorial design of experiment and varying media by introducing different levels of bile, lecithin, and digested lipids has been previously reported, but here we investigate the solubility variation of poorly soluble drugs through more complex biorelevant amphiphile interactions. A four-component mixture design was conducted to understand the solubilization capacity and interactions of bile salt, lecithin, oleate, and monoglyceride with a constant total concentration (11.7 mM) but varying molar ratios. The equilibrium solubility of seven low solubility acidic (zafirlukast), basic (aprepitant, carvedilol), and neutral (fenofibrate, felodipine, griseofulvin, and spironolactone) drugs was investigated. Solubility results are comparable with literature values and also our own previously published design of experiment studies. Results indicate that solubilization is not a sum accumulation of individual amphiphile concentrations, but a drug specific effect through interactions of mixed amphiphile compositions with the drug. This is probably due to a combined interaction of drug characteristics; for example, lipophilicity, molecular shape, and ionization with amphiphile components, which can generate specific drug-micelle affinities. The proportion of each component can have a remarkable influence on solubility with, in some cases, the highest and lowest points close to each other. A single-point solubility measurement in a fixed composition simulated media or human intestinal fluid sample will therefore provide a

    Full Text Available In the developmental literature it has been advanced that young children would not understand the specificity of nonliteral communicative acts. In this article I shall focus on young children’s ability to produce and understand different forms of humor. 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.

    This study developed and implemented a humor intervention program for school-aged children with chronic diseases. Thirty-three children with atopic dermatitis and type 1 diabetes were divided into experimental and control groups. The experimental group included 17 children while the control group included 16 children. The experimental group participated in 6 weekly sessions of a 60-minute humor intervention. The subject and type of humorous material was collected from a survey of parents and children. Outcome measures assessed pre- and post-intervention included stress, behavior profile scores, and resilience. There was a significant decrease in behavior problems and increase in resiliency in experimental group compared to control group. There was no difference in stress cortisol measures between the groups. This study was the first to examine a humor intervention for children with chronic diseases in South Korea and offers practical implications for humor interventions in pediatric nursing.

    2001-07-01

    All published research examining effects of humor and laughter on physical health is reviewed. Potential causal mechanisms and methodological issues are discussed. Laboratory experiments have shown some effects of exposure to comedy on several components of immunity, although the findings are inconsistent and most of the studies have methodological problems. There is also some evidence of analgesic effects of exposure to comedy, although similar findings are obtained with negative emotions. Few significant correlations have been found between trait measures of humor and immunity, pain tolerance, or self-reported illness symptoms. There is also little evidence of stress-moderating effects of humor on physical health variables and no evidence of increased longevity with greater humor. More rigorous and theoretically informed research is needed before firm conclusions can be drawn about possible health benefits of humor and laughter.

    Language humor is a usual phenomenon in human communication. It is an interdisciplinary subject connected with a wide range of learning. Up to now, a great deal of research has been done from the viewpoint of psychology and sociology. In the field of linguistics, some explorations have already been made in regard to its semantic and rhetorical aspects, but due attention has not been paid to it in pragmatics in that in everyday verbal communication, humorous utterances are easy to enjoy but hard to define. Apart from its capability of laughter-making, language humor is more often than not, produced to implicitly perform some communicative functions, not achievable by explicit expressions. This the - sis, based on the fruitful studies of humor, attempts to investigate the mechanisms of English humor from the perspective of a new theory 一 Co- operative Principle.

  1. Threatening the heart and mind of gender stereotypes: Can imagined contact influence the physiology of stereotype threat?

    Science.gov (United States)

    Allen, Ben; Friedman, Bruce H

    2016-01-01

    Research shows that when a gender stereotype is made salient and the target of the stereotype is asked to perform in the stereotyped domain, targets of the stereotype often perform at a lower level compared to situations when the stereotype was not made salient. The noticeable absence of female faculty and students in math and science departments at coed universities throughout the United States may increase the belief in gender stereotypes and discourage women from pursuing careers in these fields. Contact with counterstereotypical exemplars, such as female science experts, decreases belief in gender stereotypes and increases women's motivation to pursue careers in science. Thus, the present study examined whether imagining an interpersonal interaction with a counterstereotypical exemplar removes the physiological and performance effects of stereotype threat. Subjects were asked to imagine either a nature scene or meeting a female math professor, and were also assigned to either a control or stereotype threat condition. Imagination was used because studies have shown it to be an effective method of simulating interpersonal contact. Subjects were 139 young women (mean age 19 years) recruited from a pool of undergraduates. Results showed that the stereotype threat manipulation elicited greater vagal withdrawal and poorer working memory capacity during the n-back, and that vagal withdrawal was attenuated when the stereotype threat manipulation was preceded by a brief imagined interaction with a counterstereotypical exemplar. This study provides novel evidence that exposure to counterstereotypical exemplars can diminish cardiovascular reactions to salient information about threatening gender stereotypes.

    Microorganisms isolated from stressed ecosystem may prove as ideal candidates for development of bio-inoculants for stressed agricultural production systems. In the present study, moisture stress tolerant rhizobacteria were isolated from the rhizosphere of sorghum, pigeonpea, and cowpea grown under semiarid conditions in India. Four isolates KB122, KB129, KB133, and KB142 from sorghum rhizosphere exhibited plant growth promoting traits and tolerance to salinity, high temperature, and moisture stress. These isolates were identified as Bacillus spp. by 16S rDNA sequence analysis. The strains were evaluated for growth promotion of sorghum seedlings under two different moisture stress conditions (set-I, continuous 50% soil water holding capacity (WHC) throughout the experiment and set-II, 75% soil WHC for 27 days followed by no irrigation for 5 days) under greenhouse conditions. Plate count and scanning electron microscope studies indicated successful root surface colonization by inoculated bacteria. Plants inoculated with Bacillus spp. strains showed better growth in terms of shoot length and root biomass with dark greenish leaves due to high chlorophyll content while un-inoculated plants showed rolling of the leaves, stunted appearance, and wilting under both stress conditions. Inoculation also improved leaf relative water content and soil moisture content. However, variation in proline and sugar content in the different treatments under two stress conditions indicated differential effect of microbial treatments on plant physiological parameters under stress conditions.

    Cardiomyocytes (CMs) from induced pluripotent stem (iPS) cells mark an important achievement in the development of in vitro pharmacological, toxicological and developmental assays and in the establishment of protocols for cardiac cell replacement therapy. Using CMs generated from murine embryonic stem cells and iPS cells we found increased cell-matrix interaction and more matured embryoid body (EB) structures in iPS cell-derived EBs. However, neither suspension-culture in form of purified cardiac clusters nor adherence-culture on traditional cell culture plastic allowed for extended culture of CMs. CMs grown for five weeks on polystyrene exhibit signs of massive mechanical stress as indicated by α-smooth muscle actin expression and loss of sarcomere integrity. Hydrogels from polyacrylamide allow adapting of the matrix stiffness to that of cardiac tissue. We were able to eliminate the bottleneck of low cell adhesion using 2,5-Dioxopyrrolidin-1-yl-6-acrylamidohexanoate as a crosslinker to immobilize matrix proteins on the gels surface. Finally we present an easy method to generate polyacrylamide gels with a physiological Young's modulus of 55 kPa and defined surface ligand, facilitating the culture of murine and human iPS-CMs, removing excess mechanical stresses and reducing the risk of tissue culture artifacts exerted by stiff substrates.

    In Algeria, rabbit meat production is small-scale, mainly on small farms with rabbits from local populations whose productivity and growth are rather low, but which are well adapted to the local environment. Of these, farmers prefer white rabbits, with the Albino or Himalayan alleles of gene C. Our objective was to verify the appropriateness of this preference for white rabbit does over a period long enough to also assess the effect of season. From September 2006 to June 2010, reproduction data from 209 females (138 white and 71 coloured) mated by 51 males from the same population were recorded. There was neither effect of sire coat colour nor any interactions between coat colour, season and physiological status of does. There was a significant relationship between coat colour (white vs. coloured) and most reproductive traits, except receptivity and fertility, in favour of coloured females. Litter size was higher by 0.67 kits born (P=0.041), 1.27 born alive (Preproductive performance was depressed, but no more than during the following period, confirming the good adaptation of this local population to hot conditions. We can conclude that the preference of farmers for white animals is not justified because there is in this population an unfavourable genetic association between reproduction and Albino or Himalayan alleles of C gene, which needs to be explored in more detail.

  5. Physiological and health-related adaptations to low-volume interval training: influences of nutrition and sex.

    Gibala, Martin J; Gillen, Jenna B; Percival, Michael E

    2014-11-01

    Interval training refers to the basic concept of alternating periods of relatively intense exercise with periods of lower-intensity effort or complete rest for recovery. Low-volume interval training refers to sessions that involve a relatively small total amount of exercise (i.e. ≤10 min of intense exercise), compared with traditional moderate-intensity continuous training (MICT) protocols that are generally reflected in public health guidelines. In an effort to standardize terminology, a classification scheme was recently proposed in which the term 'high-intensity interval training' (HIIT) be used to describe protocols in which the training stimulus is 'near maximal' or the target intensity is between 80 and 100 % of maximal heart rate, and 'sprint interval training' (SIT) be used for protocols that involve 'all out' or 'supramaximal' efforts, in which target intensities correspond to workloads greater than what is required to elicit 100 % of maximal oxygen uptake (VO2max). Both low-volume SIT and HIIT constitute relatively time-efficient training strategies to rapidly enhance the capacity for aerobic energy metabolism and elicit physiological remodeling that resembles changes normally associated with high-volume MICT. Short-term SIT and HIIT protocols have also been shown to improve health-related indices, including cardiorespiratory fitness and markers of glycemic control in both healthy individuals and those at risk for, or afflicted by, cardiometabolic diseases. Recent evidence from a limited number of studies has highlighted potential sex-based differences in the adaptive response to SIT in particular. It has also been suggested that specific nutritional interventions, in particular those that can augment muscle buffering capacity, such as sodium bicarbonate, may enhance the adaptive response to low-volume interval training.

    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.

    Full Text Available The aim of this research was to evaluate the influence of the mechanical properties of artificial turf systems on soccer players' performance. A battery of perceptive physiological and physical tests were developed on four different structural systems of artificial turf (System 1: Compacted gravel sub-base without elastic layer; System 2: Compacted gravel sub-base with elastic layer; System 3: Asphalt sub-base without elastic layer; System 4: Asphalt sub-base with elastic layer. The sample was composed of 18 soccer players (22.44±1.72 years who typically train and compete on artificial turf. The artificial turf system with less rotational traction (S3 showed higher total time in the Repeated Sprint Ability test in comparison to the systems with intermediate values (49.46±1.75 s vs 47.55±1.82 s (S1 and 47.85±1.59 s (S2; p0.05. The physiological load was similar in all four artificial turf systems. However, players felt more comfortable on the harder and more rigid system (S4; visual analogue scale = 70.83±14.28 than on the softer artificial turf system (S2; visual analogue scale = 54.24±19.63. The lineal regression analysis revealed a significant influence of the mechanical properties of the surface of 16.5%, 15.8% and 7.1% on the mean time of the sprint, the best sprint time and the maximum mean speed in the RSA test respectively. Results suggest a mechanical heterogeneity between the systems of artificial turf which generate differences in the physical performance and in the soccer players' perceptions.

    The influence of constant lightening on biomarkers of ageing and rates of male rats aging was studied. It was revealed that the maintenance of rats in the constant lightening regime starting from the age of one month results in accelerated ageing of the organism, the reduction of the phases progressive and stable growth, early occurrence of presenile and senile periods, to the earlier occurrence of water-and-salt metabolism imbalance, accelerate the process of "aging" of the antioxidant system in comparison with the rates of the control group. On the contrary, the maintenance of rats in the constant lightening regime starting from the age of fourteen months slows ageing of the organism, increases body growth, delays appearance of pathological changes in the urine, slows down the "aging" of the enzymatic components of the antioxidant system.

    Full Text Available Instructor humor serves a wide range of functions in educational contexts. This paper reports on a study that investigated the functions of instructors' humorous verbalizations in academic classrooms at a university where English is used as a second language. Data were collected through audio-recordings and classroom observations. The results of an inductive analysis led to the development of three major categories, namely “foregrounding form”, “reinforcing meaning” and “highlighting cultural dissimilarities”. These categories represented the strategies that served as instructional functions of humor in the context of L2 (second language education. Findings indicate that using verbal humor in L2 classrooms offers opportunities to facilitate access to L2 linguistic and cultural knowledge resources that are embedded in humorous exchanges. Additionally, the findings suggest that L2 instructors must have specific (socio linguistic and sociocultural humor competence to use humor to engage learners and communicate finer aspects of the L2. The implications of the findings are explored within the context of second language learning and teaching.

    2009-01-01

    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.

    The human organism is an integrated network where complex physiologic systems, each with its own regulatory mechanisms, continuously interact, and where failure of one system can trigger a breakdown of the entire network. Identifying and quantifying dynamical networks of diverse systems with different types of interactions is a challenge. Here, we develop a framework to probe interactions among diverse systems, and we identify a physiologic network. We find that each physiologic state is characterized by a specific network structure, demonstrating a robust interplay between network topology and function. Across physiologic states the network undergoes topological transitions associated with fast reorganization of physiologic interactions on time scales of a few minutes, indicating high network flexibility in response to perturbations. The proposed system-wide integrative approach may facilitate new dimensions to the field of systems physiology.

This is also true both for Italy and for its Piemonte region, in which famous and renowned wines (such as Barolo and Barbaresco) are produced. Grapevine productivity depends on several factors including soil fertility, management practices, climate and meteorology. In particular, concerning the latter, there is a need for a reliable assessment of the effects of a changing climate on its yield and quality. However, in this respect, it is essential to understand how and how much climate and meteorology affect grape productivity and quality, since only few studies related to few regions in the world have been produced. In this context, crop models are essential tools for investigating the effects of climate change on crop development and growth via the integration of existing knowledge of crop physiology relating to changing environmental conditions. Nevertheless, crop models were developed and applied mainly for studying the responses to climate change of annual crops (e.g. cereals); whilst appropriate crop models and application of these are still limited for tree crops such as grapevine. The rationale of the study, included in the MACSUR2 JPI FACCE project, is to use the third generation land surface model UTOPIA (University of TOrino model of land Process Interaction with Atmosphere) [1], in order to evaluate all components of hydrological and energy budget, as well as soil and canopy parameters, on a specific subset of land use, the vineyards. A preliminary step of this work has been to compare the datasets resulted from the calculations made by the UTOPIA and some experimental datasets acquired within vineyards by our team in the past experiments. The reason for such control is to ensure that UTOPIA outputs could be considered as sufficiently representative of the climatology of vineyards. Thus, some Piedmontese vineyards were selected

    The present study was conducted to assess the influence of dietary zinc nanoparticles (size 50 nm) on the growth, biochemical constituents, enzymatic antioxidant levels and the nonspecific immune response of the freshwater prawn, Macrobrachium rosenbergii post larvae (PL). The concentrations of dietary supplement zinc nanoparticles (ZnNPs) were 0, 10, 20, 40, 60 and 80 mg kg(-1) with the basal diet, and the level of Zn in ZnNP-supplemented diets were 0.71, 10.61, 20.73, 40.73, 60.61 and 80.60 mg kg(-1), respectively. ZnNP-incorporated diets were fed to M. rosenbergii PL (initial body weight, 0.18 ± 0.02 g) in a triplicate experimental setup for a period of 90 days. ZnNP supplemented feed fed PL up to 60 mg kg(-1) showed significantly (P rosenbergii PL. Thus, the study suggests that up to 60 mg ZnNPs kg(-1) can be supplemented for regulating survival, growth and immunity of M. rosenbergii.

  20. The influence of the cage environment on rodent physiology and behavior: Implications for reproducibility of pre-clinical rodent research.

    The reproducibility of pre-clinical research is an important concern that is now being voiced by constituencies that include the National Institutes of Health, the pharmaceutical industry, Congress, the public and the scientific community. An important facet of performing and publishing well-controlled reproducible pre-clinical research is to stabilize and more completely define the environment of the animal subjects. Scientists who use rodents in research generally recognize the importance of maintaining a stable animal environment. However, despite a theoretical and general awareness of these issues, many may lack a true appreciation of how significantly even seemingly minor variations in the environment can affect research outcomes. The purpose of this article is to help investigators gain a more comprehensive and substantiated understanding of the potentially significant impact of even seemingly minor environmental changes on the animals and the data. An important caveat to this article is that the examples presented were selected from a very large literature, admittedly in order to illustrate certain points. The goal of this article is not to provide an overview of the entire literature on how the environment affects rodents but rather to make preclinical scientists more aware of how these factors can potentially influence the experimental data and contribute to poor reproducibility of research.

    Purpose To compare the effects of age and near phoria on interpupillary distance measured at far (FIPD) and near (NIPD) using the Viktorin’s and pupillometer (PD-5) methods. Methods Interpupillary distance (IPD) by Viktorin’s method and the corneal reflex pupillometer (PD-5) method, as well as near heterophoria by the Saladin near point card, were each obtained on 133 randomly selected normal subjects aged 20–67 years. Comparison within and between techniques, influence of age on IPD, and near heterophoria were assessed. Results The mean FIPD varied significantly from the NIPD (P 0.05) for FIPD, and −3.1 mm and 2.9 mm (P > 0.05) for NIPD. Both IPDs varied significantly across age groups (P 0.04; P < 0.03, both techniques). Conclusion The difference between FIPD and NIPD (about 4.4 mm in Arab males) was observed independent of the technique used. The Viktorin’s and the PD-5 methods of IPD assessment resulted in similar values, and therefore, could be interchangeably used. However, caution is advised in cases of high power refractive corrections as the difference could vary from −4 mm to +3 mm (FIPD) and −3 mm to +3 mm (NIPD). Both IPDs have demonstrated an increase until the patients are in their early 40s, and a slight decrease has been observed thereafter. Age and NIPD were significantly associated with heterophoria in our subjects. PMID:23620654

Outline of vase experiment covered 5 objects (control without addition of cadmium and 4 objects with increasing amount of cadmium in amount from 10 to 80 mg.kg-1 d.m. soil, and within each object two variants: soil without (-T and with (+T addition of fungi of Trichoderma (+T in shape of granulated preparation of Trianum–G in amount of 750 g.m-3 soil. Increasing amount of cadmium in surface caused decrease of harvest size of roots and above ground parts of maize, but inoculation of surface by Trichoderma fungi softened those changes. Amount of cadmium in plants was increasing promotionally to increasing amount of that metal in soil, but the presence of fungi of Trichoderma type caused decrease of phytoavailability cadmium by above ground parts of maize. Decrease parameters of chlorophyll fluorescence F0, FM, Fv, Fv/FM Fv/F0 showed lack of disturbances in photosynthetic apparatus of maize despite decrease the amount of chlorophyll in leaves under the influence of inserted cadmium doses to soil.

    Glaucoma is the primary cause of irreversible blindness worldwide associated with high intraocular pressure (IOP). Elevated intraocular pressure will affect the normal aqueous humor outflow, resulting in deformation of iris. However, the deformation ability of iris is closely related to its material properties. Meanwhile, the passive deformation of the iris aggravates the pupillary block and angle closure. The nature of the interaction mechanism of iris deformation and aqueous humor fluid flow has not been fully understood and has been somewhat a controversial issue. The purpose here was to study the effect of IOP, localization, and temperature on the flow of the aqueous humor and the deformation of iris interacted by aqueous humor fluid flow. Based on mechanisms of aqueous physiology and fluid dynamics, 3D model of anterior chamber (AC) was constructed with the human anatomical parameters as a reference. A 3D idealized standard geometry of anterior segment of human eye was performed. Enlarge the size of the idealization geometry model 5 times to create a simulation device by using 3D printing technology. In this paper, particle image velocimetry technology is applied to measure the characteristic of fluid outflow in different inlet velocity based on the device. Numerically calculations were made by using ANSYS 14.0 Finite Element Analysis. Compare of the velocity distributions to confirm the validity of the model. The fluid structure interaction (FSI) analysis was carried out in the valid geometry model to study the aqueous flow and iris change. In this paper, the validity of the model is verified through computation and comparison. The results indicated that changes of gravity direction of model significantly affected the fluid dynamics parameters and the temperature distribution in anterior chamber. Increased pressure and the vertical position increase the velocity of the aqueous humor fluid flow, with the value increased of 0.015 and 0.035 mm/s. The results

    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

    Modern non-thermal atmospheric pressure plasma sources enable controllable interaction with biological systems. Their future applications - e.g. wound management - are based on their unique mixture of reactive components sparking both stimulatory as well as inhibitory processes. To gain detailed understanding of plasma-cell interaction and with respect to risk awareness, key mechanisms need to be identified. This study focuses on the impact of an argon non-thermal atmospheric pressure plasma jet (kINPen 09) on human HaCaT keratinocytes. With increasing duration, cell viability decreased. In accordance, cells accumulated in G2/M phase within the following 24 h. DNA single-strand breaks were detected immediately after treatment and receded in the aftermath, returning to control levels after 24 h. No directly plasma-related DNA double-strand breaks were detected over the same time. Concurrently, DNA synthesis decreased. Coincident with treatment time, an increase in intracellular 2',7'-dichlorodihydrofluorescein diacetate (H(2)DCFDA) conversion increased reactive oxygen species (ROS) levels. The radical scavenging activity of culture medium crucially influenced these effects. Thus, ROS changed DNA integrity, and the effectiveness of cellular defence mechanisms characterises the interaction of non-thermal plasma and eukaryotic cells. Effects were time-dependent, indicating an active response of the eukaryotic cells. Hence, a stimulation of eukaryotic cells using short-term non-thermal plasma treatment seems possible, eg in the context of chronic wound care. Long-term plasma treatments stopped in cell proliferation and apoptosis, which might be relevant in controlling neoplastic conditions.

    The wild boar population has increased enormously in all of Europe over the last decades and caused problems like crop damage, transmission of diseases, and vehicle accidents. Therefore, it is necessary to investigate the underlying causes of this increase in order to be able to manage populations effectively. The purpose of this study was to analyse how environmental (food and climate) and physiological factors (maternal weight and age) as well as hunting and population density influence the litter size of wild boar populations in Northern Germany. The mean litter size in the studied population for the whole period was 6.6 (range 1–12), which is one of the highest in all of Europe. Litter size was positively influenced by maternal body weight, higher mast yield of oak as well as higher temperature in combination with higher precipitation in summer. Only higher temperature or only higher precipitation in summer however had a negative effect on litter size production. Probably,weather and food conditions act via maternal bodyweight on the litter size variation in wild boar. Hunting as well a s population density did not affect the litter size variation in this study which might indicate that wild boar population did not reach carrying capacity yet.

    Mild dietary zinc deprivation in humans and rodents has little effect on blood plasma zinc levels, and yet cellular consequences of zinc depletion can be detected in vascular and other tissues. We proposed that a zinc-regulated humoral factor might mediate the effects of zinc deprivation. Using a novel approach, primary rat vascular smooth muscle cells (VSMCs) were treated with plasma from zinc-deficient (2500 genes, compared to incubation of cells with zinc-adequate rat plasma. We demonstrated that this effect was caused by a low-molecular-weight (∼2-kDa) zinc-regulated humoral factor but that changes in gene expression were mostly reversed by adding zinc back to zinc-deficient plasma. Strongly regulated genes were overrepresented in pathways associated with immune function and development. We conclude that zinc deficiency induces the production of a low-molecular-weight humoral factor whose influence on VSMC gene expression is blocked by plasma zinc. This factor is therefore under dual control by zinc.

    The opacification of Akreos Adapt (Bausch & Lomb, Rochester; NY) intraocular lens (IOL) has been previously reported in Literature. A metabolic change in aqueous humour was considered as the main trigger factor to IOL opacification. We report our case and discuss the association with Ex-PRESS, highlighting the particular pattern of IOL opacification and its possible relation with the intraocular convective motions of the aqueous. We analyzed our case using both digital slit lamp acquisition and OCT Visante (Zeiss, Germany) images. A literature review was conducted to evaluate our results with that previously reported. The role of a relative stationary flow was reported as suggested concurrent mechanism in IOL opacification phenomenon.

    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.

    Although life-history trade-offs result from the differential acquisition and allocation of nutritional resources to competing physiological functions, many aspects of this topic remain poorly understood. Wing-polymorphic insects, which possess alternative morphs that trade off allocation to flight capability versus early reproduction, provide a good model system for exploring this topic. In this study, we used the wing-polymorphic cricket Gryllus firmus to test how expression of the flight capability versus reproduction trade-off was modified across a heterogeneous protein-carbohydrate nutritional landscape. Newly molted adult female long- and short-winged crickets were given one of 13 diets with different concentrations and ratios of protein and digestible carbohydrate; for each cricket, we measured consumption patterns, growth and allocation to reproduction (ovary mass) versus flight muscle maintenance (flight muscle mass and somatic lipid stores). Feeding responses in both morphs were influenced more by total macronutrient concentration than by protein-carbohydrate ratio, except at high-macronutrient concentration, where protein-carbohydrate balance was important. Mass gain tended to be greatest on protein-biased diets for both morphs, but was consistently lower across all diets for long-winged females. When long-winged females were fed high-carbohydrate foods, they accumulated greater somatic lipid stores; on high-protein foods, they accumulated greater somatic protein stores. Food protein-carbohydrate content also affected short-winged females (selected for early reproductive onset), which showed dramatic increases in ovary size, including ovarian stores of lipid and protein, on protein-biased foods. This is the first study to show how the concentration and ratio of dietary protein and carbohydrate affects consumption and allocation to key physiological features associated with the reproduction-dispersal life-history trade-off. © 2015.

    OBJECTIVE The optimal site for placement of tissue oxygen probes following traumatic brain injury (TBI) remains unresolved. The authors used a previously described swine model of focal TBI and studied brain tissue oxygen tension (PbtO2) at the sites of contusion, proximal and distal to contusion, and in the contralateral hemisphere to determine the effect of probe location on PbtO2 and to assess the effects of physiological interventions on PbtO2 at these different sites. METHODS A controlled cortical impact device was used to generate a focal lesion in the right frontal lobe in 12 anesthetized swine. PbtO2 was measured using Licox brain tissue oxygen probes placed at the site of contusion, in pericontusional tissue (proximal probe), in the right parietal region (distal probe), and in the contralateral hemisphere. PbtO2 was measured during normoxia, hyperoxia, hypoventilation, and hyperventilation. RESULTS Physiological interventions led to expected changes, including a large increase in partial pressure of oxygen in arterial blood with hyperoxia, increased intracranial pressure (ICP) with hypoventilation, and decreased ICP with hyperventilation. Importantly, PbtO2 decreased substantially with proximity to the focal injury (contusion and proximal probes), and this difference was maintained at different levels of fraction of inspired oxygen and partial pressure of carbon dioxide in arterial blood. In the distal and contralateral probes, hypoventilation and hyperventilation were associated with expected increased and decreased PbtO2 values, respectively. However, in the contusion and proximal probes, these effects were diminished, consistent with loss of cerebrovascular CO2 reactivity at and near the injury site. Similarly, hyperoxia led to the expected rise in PbtO2 only in the distal and contralateral probes, with little or no effect in the proximal and contusion probes, respectively. CONCLUSIONS PbtO2 measurements are strongly influenced by the distance from the

    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

    In this chapter we discuss the generation of humorous acts by embodied agents. It is observed that in future interfaces that are meant to allow natural interaction, embodied agents can play useful roles. Humor plays an important role in human-human interaction and therefore it is useful to investigate how it should become part of the internal modeling of an embodied agent, along with intelligence and emotion modeling. Employment of embodied agents will also give rise to expectations concernin...

    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 an...

    Full Text Available 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.

    2015-06-01

    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.

    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.

  8. Whole vitreous humor dissection for vitreodynamic analysis.

    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.

    Full Text Available The nervous system is the target for acute encephalitic viral infections, as well as a reservoir for persisting viruses. Intrathecal antibody (Ab synthesis is well documented in humans afflicted by infections associated with neurological complications, as well as the demyelinating disease, multiple sclerosis. This review focuses on the origin, recruitment, maintenance, and biological relevance of Ab-secreting cells (ASC found in the central nervous system (CNS following experimental neurotropic RNA virus infections. We will summarize evidence for a highly dynamic, evolving humoral response characterized by temporal alterations in B cell subsets, proliferation, and differentiation. Overall local Ab plays a beneficial role via complement-independent control of virus replication, although cross or self-reactive Ab to CNS antigens may contribute to immune-mediated pathogenesis during some infections. Importantly, protective Ab exert anti-viral activity not only by direct neutralization, but also by binding to cell surface-expressed viral glycoproteins. Ab engagement of viral glycoproteins blocks budding and mediates intracellular signaling leading to restored homeostatic and innate functions. The sustained Ab production by local ASC, as well as chemokines and cytokines associated with ASC recruitment and retention, are highlighted as critical components of immune control.

    In the context of immunity, pattern recognition is the art of discriminating friend from foe and innocuous from noxious. The basis of discrimination is the existence of evolutionarily conserved patterns on microorganisms, which are intrinsic to these microorganisms and necessary for their function and existence. Such immutable or slowly evolving patterns are ideal handles for recognition and have been targeted by early cellular immune defence mechanisms such as Toll-like receptors, NOD-like receptors, RIG-I-like receptors, C-type lectin receptors and by humoral defence mechanisms such as the complement system. Complement is a proteolytic cascade system comprising around 35 different soluble and membrane-bound proteins. It constitutes a central part of the innate immune system, mediating several major innate effector functions and modulating adaptive immune responses. The complement cascade proceeds via controlled, limited proteolysis and conformational changes of constituent proteins through three activation pathways: the classical pathway, the alternative pathway and the lectin pathway, which converge in common effector functions. Here, we review the nature of the pattern recognition molecules involved in complement activation, as well as their close relatives with no or unknown capacity for activating complement. We proceed to examine the composition of the pattern recognition complexes involved in complement activation, focusing on those of the lectin pathway, and arrive at a new model for their mechanism of operation, supported by recently emerging evidence.

    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.

    Ilya Metchnikoff and Paul Ehrlich shared the 1908 Nobel Prize in Physiology or Medicine - Metchnikoff for discovering the major types and functions of phagocytes and Ehrlich for discovering the types of blood leukocytes, helping to uncover how to generate and use antibodies to protect against bacterial toxins, and formulating the receptor concept of antibodies binding to antigens. In 1908 phagocytic and humoral defences were thought to be unrelated but it was realized much later that they influence one other. Thus, it is fitting that the 1908 Nobel Laureates in Physiology or Medicine remain closely connected in the minds of modern immunologists. Metchnikoff and Ehrlich shared qualities of natural curiosity and tenacity coupled with remarkable inductive-mechanistic thinking and a zest for experimentation. However, their approaches to and methods of research were decidedly different - Metchnikoff's by evolutionary biology and an approach to experimentation via microscopy and Ehrlich's by an imaginative side-chain theory and organic chemistry.

    Full Text Available This study evaluated the influence of the phenolic compounds carvacrol (CAR and thymol (THY on some physiological characteristics and on the modulation of the secretion of some staphylococcal virulence factors, that is, coagulase and enterotoxin. This study also investigated possible mechanisms for the establishment of the anti-staphylococcal activity of these compounds. Sublethal concentrations (0.3 and 0.15 µL/mL of CAR and THY inhibited the activity of the enzymes coagulase and lipase and led to a decrease in salt tolerance. At the tested sublethal concentrations, both CAR and THY led to a total suppression of enterotoxin production. The loss of a 260-nm-absorbing material and an efflux of potassium ions occurred immediately after the addition of CAR and THY at 0.6 and 1.2 µL/mL and increased up to 120 min of exposure. Electron microscopy of cells exposed to CAR and THY (0.6 µL/mL revealed that individual cells appeared to be deformed, with projections of cellular material. The observations of leakage of cellular material and an altered cell surface suggest that gross damage to a cell's cytoplasmic membrane, which results in a disruption in protein secretion, could be responsible for the anti-staphylococcal properties of CAR and THY.

    Trans-trans farnesol (tt-farnesol) is a bioactive sesquiterpene alcohol commonly found in propolis (a beehive product) and citrus fruits, which disrupts the ability of Streptococcus mutans (S. mutans) to form virulent biofilms. In this study, we investigated whether tt-farnesol affects cell-membrane function, acid production and/or acid tolerance by planktonic cells and biofilms of S. mutans UA159. Furthermore, the influence of the agent on S. mutans gene expression and ability to form biofilms in the presence of other oral bacteria (Streptococcus oralis (S. oralis) 35037 and Actinomyces naeslundii (A. naeslundii) 12104) was also examined. In general, tt-farnesol (1 mmol x L(-1)) significantly increased the membrane proton permeability and reduced glycolytic activity of S. mutans in the planktonic state and in biofilms (P biofilms after introduction of 1% sucrose. S. oralis (a non-cariogenic organism) became the major species after treatments with tt-farnesol, whereas vehicle-treated biofilms contained mostly S. mutans (>90% of total bacterial population). However, the agent did not affect significantly the expression of S. mutans genes involved in acidogenicity, acid tolerance or polysaccharide synthesis in the treated biofilms. Our data indicate that tt-farnesol may affect the competitiveness of S. mutans in a mixed-species environment by primarily disrupting the membrane function and physiology of this bacterium. This naturally occurring terpenoid could be a potentially useful adjunctive agent to the current anti-biofilm/anti-caries chemotherapeutic strategies.

    2017-02-01

    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.

    This work aimed to consider the hazardous side effect of eye floaters treatment with Q-switched Nd:YAG laser on the protein and viscoelastic properties of the vitreous humor, and evaluate the protective role of vitamin C against laser photo disruption. Five groups of New Zealand rabbits were divided as follows: control group for (n = 3) without any treatment, the second group (n = 9) treated with Q-switched Nd:YAG laser energy of 5 mJ × 100 pulse delivered to the anterior, middle, and posterior vitreous, respectively (n = 3 for each). The third group (n = 9) received a daily dose of 25 mg/kg body weight vitamin C for 2 weeks, and then treated with laser as the previous group. The fourth group (n = 9) treated with 10 mJ 9 50 pulse delivered to the anterior, middle, and posterior vitreous, respectively (n = 3 rabbits each). The fifth group (n = 9) received a daily dose of 25 mg/kg body weight vitamin C for 2 weeks, and then treated with laser as the previous group. After 2 weeks of laser treatment, the protein content, refractive index (RI), and the rheological properties of vitreous humor, such as consistency, shear stress, and viscosity, were determined. The results showed that, the anterior vitreous group exposed to of 5 mJ × 100 pulse and/or supplemented with vitamin C, showed no obvious change. Furthermore, all other treated groups especially for mid-vitreous and posterior vitreous humor showed increase in the protein content, RI and the viscosity of vitreous humor. The flow index remained below unity indicating the non-Newtonian behavior of the vitreous humor. Application of Q-switched Nd:YAG laser should be restricted to the anterior vitreous humor to prevent the deleterious effect of laser on the gel state of the vitreous humor.

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.

The instrument was applied to a sample of 621 participants. It has extracted factors with oblique rotation, analysis of factorial loadings and internal analysis of consistency. The results have pointed out three main factors: mood with friends and colleagues (α=0.70; influences on moods (α=0.70, and humor in adverse situations (α=0.55. The internal consistency suggests that for the Brazilian context some items can be improved, especially concerning the humor in adverse situations, in order to enhance the precision factor. However, it provides an acceptable internal consistency.

    Conclusions: Although the general pattern of avian physiology applies to cranes, we have identified many physiological mechanisms (e.g., effects of disturbance) that need further study. Studies with cranes are expensive compared to those done with domestic fowl because of the crane's larger size, low reproductive rate, and delayed sexual maturity. To summarize, the crane reproductive system is composed of physiological and anatomical elements whose function is controlled by an integrated neural-endocrine system. Males generally produce semen at a younger age than when females lay eggs. Eggs are laid in clutches of two (1 to 3), and females will lay additional clutches if the preceding clutches are removed. Both sexes build nests and incubate the eggs. Molt begins during incubation and body molt may be completed annually in breeding pairs. However, remiges are replaced sequentially over 2 to 3 years, or abruptly every 2 to 3 years in other species. Most immature birds replace their juvenal remiges over a 2 to 3 year period. Stress interferes with reproduction in cranes by reducing egg production or terminating the reproductive effort. In other birds, stress elevates corticosterone levels and decreases LHRH release. We know little about the physiological response of cranes to stress.

    Humor study enjoys a long history with a variety of theories and methods. Among them, the pragmatic approach is a relatively new and vigorous perspective. Scholars have adopted the cooperative principle and relevance theory to explain humor. However, as to studying humor from the perspective of pragmatic presupposition, very few researches have been done in this regard. Such being the case, this paper will use presupposition as a tool to analyze humor in Lost in Thailand which is a sensational comedy in China. By analyzing cases from this film, the paper aims to explore how presupposition functions in the production of humorous effect, and to provide some new insights into humor study.

    Humor plays an indispensable part in human communication. This thesis is a tentative analysis of verbal humor under-standing within the framework of Relevance Theory. This paper, using The Big Bang Theory as a corpus, analyzes the humor gener-ated in the cognitive process of searching for relevance. According to the Relevance Theory, the understanding of humor is a pro-cess in which the hearer finds"relevance"in what seems"irrelevant". The author hopes that this analysis can help more people un-derstand and appreciate the humor in The Big Bang Theory. And meanwhile their personal sense of humor can also be improved.

    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.

    The purpose of this study was to examine the influence of different team formation methods on the physiological responses to and time-motion characteristics of 4-a-side small-sided games (SSG4) in young soccer players. Thirty-two young soccer players (age 16.2 ± 0.7 years; height 172.9 ± 6.1 cm; body mass 64.1 ± 7.7 kg) voluntarily participated in this study. Anthropometric measurements, technical tests, and maximum oxygen uptake (V[Combining Dot Above]O2max) tests were carried out on the players. The SSG4 teams were then created using 4 different methods: according to the coaches' subjective evaluation (CE), technical scores (TS), V[Combining Dot Above]O2max (AP), and V[Combining Dot Above]O2max multiplied by TSs (CG). The teams thus created played 4 bouts of SSG4 at 2-day intervals. During the SSG4, heart rate (HR) responses, distance covered, and time spent in HRmax zones were recorded. In addition, rating of perceived exertion (RPE) and blood lactate level (La) were determined at the end of the last bout of each SSG4. Percent of HRmax (%HRmax), La, and RPE responses during SSG4 were significantly higher for teams chosen according to AP and CG compared with that according to CE and TS (p teams chosen by AP and CG spent significantly more time in zone 4 (>90% HRmax ) and covered a greater distance in the high-intensity running zone (>18 km·h) than did teams formed according to TS. Moreover, AP teams covered significantly greater total distance than TS teams did (p teams in SSG4 should be formed according to the players' V[Combining Dot Above]O2max values or the values calculated using both the V[Combining Dot Above]O2max and technique scores.

  14. Wash flow disturbance and summer wash flow in the Mojave Desert: Influence on dispersion, production, and physiological functioning of dominant shrubs

    Science.gov (United States)

    Newlander, April

    In many Mojave Desert ecosystems, water infiltrates to root-zones in greatest proportion via washes. As such, washes have a pronounced effect on plant dispersion and size across these landscapes. Desert roads alter the natural spatial patterns of washes on alluvial fans (locally called bajadas) and potentially affect plant production and distribution. As a winter-rainfall dominated ecosystem, climate changes in the Mojave Desert that increase summer precipitation may also play an important role in altering vegetation processes influenced by washes. Road effects on the spatial distribution of desert plants on a Mojave Desert bajada were examined using remotely sensed LiDAR data and ground based measurements of plant size. Plant physiological responses to summer wash flow were also quantified by measuring gas exchange and water status of two dominant perennial species, Larrea tridentata and Ambrosia dumosa. Larrea and Ambrosia plants were nearly 7x and 4x larger where wash flow has been enhanced by road culverts, relative to undisturbed areas and areas where flow has been cut-off by the presence of a road/railroad. Clustering of large plants occurred along wash margins, with clustering most pronounced in areas of enhanced wash flow. No clustering was found where wash flow has been eliminated. For ecophysiological traits, both species showed pronounced responses to the pulse of water; however, these responses varied as a function of distance from wash. Larrea plants within 3 m and Ambrosia plants within ca. 2 m from the wash responded to the pulse of water. Leaf phenology dictated the timing of carbon gain as Larrea experienced a rapid but short-lived increase in stomatal conductance compared to a significant response for over a month following the pulse for Ambrosia. These results indicate that disturbance of desert washes has a pronounced impact on vegetation structure, and changing climatic conditions that impact plant function could potentially lead to even

    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

    Ventis, W L; Higbee, G; Murdock, S A

    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.

    Everybody loves a comic--or do they? A Human Resources Department picked up a pattern when several departing employees, all excellent performers, said they liked their jobs but felt "excluded" from the camaraderie. One said he'd found the humor "barbed." Another said she's never seen anything funny in jokes that seemed to convulse everyone else. The past five years have been so gloomy, economically speaking, that, in many hospitals and health care organizations, laughter is a mega-event. But lately I've been listening to what employees joke about and watching how their humor affects others. Physician executives need to be alert to some kinds of humor that are weapons used by employees against other employees, their managers, and the company generally.

    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.

    Pride and Prejudice, published in 1813, is the most influential work of British female writer Jane Austen (1775-1817). By analyzing Jane Austen's representative novel, Pride and Prejudice, we are convinced by the excellent humor and irony used in it. Irony in Pride and Prejudice is mainly embodied in Austen's verbal irony, situational irony and dramatic irony. Under the perspective of stylistics, this paper analyzes dialogues, descriptive and commentary language and the arrangement of the whole plots of Austen's Pride and Prejudice to show how the different tones of humor and irony are reflected in the novel. This paper also focuses on the significance in portraying the characteristics of the roles and theme performance of humor and irony used in Pride and Prejudice, which help us to appreciate the satire literature.

    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.

    We have previously reported low concentrations of plasma ascorbate and low dietary vitamin C intake in the older Indian population and a strong inverse association of these with cataract. Little is known about ascorbate levels in aqueous humor and lens in populations habitually depleted of ascorbate and no studies in any setting have investigated whether genetic polymorphisms influence ascorbate levels in ocular tissues. Our objectives were to investigate relationships between ascorbate concentrations in plasma, aqueous humor and lens and whether these relationships are influenced by Single Nucleotide Polymorphisms (SNPs) in sodium-dependent vitamin C transporter genes (SLC23A1 and SLC23A2). We enrolled sixty patients (equal numbers of men and women, mean age 63 years) undergoing small incision cataract surgery in southern India. We measured ascorbate concentrations in plasma, aqueous humor and lens nucleus using high performance liquid chromatography. SLC23A1 SNPs (rs4257763, rs6596473) and SLC23A2 SNPs (rs1279683 and rs12479919) were genotyped using a TaqMan assay. Patients were interviewed for lifestyle factors which might influence ascorbate. Plasma vitamin C was normalized by a log10 transformation. Statistical analysis used linear regression with the slope of the within-subject associations estimated using beta (β) coefficients. The ascorbate concentrations (μmol/L) were: plasma ascorbate, median and inter-quartile range (IQR), 15.2 (7.8, 34.5), mean (SD) of aqueous humor ascorbate, 1074 (545) and lens nucleus ascorbate, 0.42 (0.16) (μmol/g lens nucleus wet weight). Minimum allele frequencies were: rs1279683 (0.28), rs12479919 (0.30), rs659647 (0.48). Decreasing concentrations of ocular ascorbate from the common to the rare genotype were observed for rs6596473 and rs12479919. The per allele difference in aqueous humor ascorbate for rs6596473 was -217 μmol/L, p ascorbate of -0.085 μmol/g, p ascorbate on aqueous humor ascorbate were higher for the GG

    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.
