    3,4-methylenedioxymethamphetamine (MDMA) produces "prosocial" effects that contribute to its recreational use. Few studies have examined the cognitive and behavioral mechanisms by which MDMA produces these effects. Here we examined the effect of MDMA on a specific prosocial effect, i.e. generosity, using a task in which participants make decisions about whether they or another person will receive money (Welfare Trade-Off Task; WTT). The project included one study without drug administration and one with MDMA. In Study 1, we administered the WTT to healthy adults (N = 361) and examined their performance in relation to measures of personality and socioeconomic status. In Study 2, healthy volunteers with MDMA experience (N = 32) completed the WTT after MDMA administration (0, 0.5, or 1.0 mg/kg). As expected, in both studies participants were more generous with a close friend than an acquaintance or stranger. In Study 1, WTT generosity was related to household income and trait Agreeableness. In Study 2, MDMA (1.0 mg/kg) increased generosity toward a friend but not a stranger, whereas MDMA (0.5 mg/kg) slightly increased generosity toward a stranger, especially among female participants. These data indicate that the WTT is a valuable, novel tool to assess a component of prosocial behavior, i.e. generosity to others. The findings support growing evidence that MDMA produces prosocial effects, but, as with oxytocin, these appear to depend on the social proximity of the relationships. The brain mechanisms underlying the construct of generosity, or the effects of MDMA on this measure, remain to be determined. © The Author(s) 2015.

    Although previous research has demonstrated that generosity can lead to status gains, the converse effect of status on generosity has received less attention. This is a significant gap because groups and society at large rely on the beneficence of all members, especially those holding high-status positions. More broadly, research on the psychology of status remains largely unexplored, which is striking in light of the attention given to other forms of social hierarchy, such as power. The current work focuses on the psychology of status and explores the interactive effects of status and legitimacy on generosity. In particular, we hypothesize that status will decrease generosity when the status hierarchy is perceived as legitimate because status can inflate views of one's value to the group and sense of deservingness. In contrast, we hypothesize that status increases generosity when the status hierarchy is perceived as illegitimate, due to efforts to restore equity through one's generosity. Our results support these hypotheses across 6 studies (a field study and 5 experiments) and empirically demonstrate that the effects of status and legitimacy on generosity can be attributed to concerns about equity in status allocation.

    Full Text Available Generosity is greatly valued and admired, but can it sometimes be unappealing? The current study investigated 8- to 10-year-old children’s (N=128 preference for generous individuals, and the effects of social comparison on their preferences. In Experiment 1, children showed a strong preference for a generous to a stingy child; however, this preference was significantly reduced in a situation that afforded children a comparison of their own (lesser generosity to that of another child. In Experiment 2, children’s liking for a generous individual was not reduced when that individual was an adult, suggesting that similarity in age influences whether a child engages in social comparison. These findings indicate that, by middle childhood, coming up short in comparison with a peer can decrease one’s liking for a generous individual.

    Changes in socio-emotional behavior and conduct, which are characteristic symptoms of frontal lobe damage, have less often been described in patients with focal subcortical injuries. We report on a case of pathological generosity secondary to a left lenticulocapsular stroke with hypoperfusion of several anatomically intact cortical areas. A 49-year-old man developed excessive and persistent generosity as he recovered from a left lenticulocapsular hematoma. His symptoms resembled an impulse control disorder. (99m)Tc-HMPAO SPECT demonstrated hypoperfusion mostly in the ipsilateral striatum, dorsolateral, and orbitofrontal cortex. This case study adds pathological generosity to the range of behavioral changes that may result from discrete unilateral lesions of the lenticular nucleus and nearby pathways. In our particular case, post-stroke pathological generosity was not ascribable to disinhibition, apathy, mania, or depression. Because pathological generosity may lead to significant distress and financial burden upon patients and their families, it may warrant further consideration as a potential type of impulse control disorder.

    Empathy is related to a variety of prosocial behaviors, but the brain mechanisms producing the experience of empathy have not been fully characterized. This study investigated whether the experience of empathy raises oxytocin levels and affects subsequent generosity toward strangers. Short video clips of an emotional scene and an unemotional scene were used as stimuli. Participants rated the emotions they experienced and then played a $40 ultimatum game to gauge their generosity. We found that empathy was associated with a 47% increase in oxytocin from baseline. We also found the empathy-oxytocin response was stronger in women than in men. Higher levels of empathy were also associated with more generous monetary offers toward strangers in the ultimatum game. Our findings provide the first evidence that oxytocin is a physiologic signature for empathy and that empathy mediates generosity.

    Recent research has highlighted the role of prosocial personality traits-agreeableness and honesty-humility-in egalitarian distributions of wealth in the dictator game. Expanding on these findings, we ran two studies to examine individual differences in two other forms of prosociality-generosity and reciprocity-with respect to two major models of personality, the Big Five and the HEXACO. Participants (combined N = 560) completed a series of economic games in which allocations in the dictator game were compared with those in the generosity game, a non-constant-sum wealth distribution task where proposers with fixed payoffs selected the size of their partner's payoff ("generosity"). We further examined positive and negative reciprocity by manipulating a partner's previous move ("reciprocity"). Results showed clear evidence of both generosity and positive reciprocity in social preferences, with allocations to a partner greater in the generosity game than in the dictator game, and greater still when a player had been previously assisted by their partner. There was also a consistent interaction with gender, whereby men were more generous when this was costless and women were more egalitarian overall. Furthermore, these distinct forms of prosociality were differentially predicted by personality traits, in line with the core features of these traits and the theoretical distinctions between them. HEXACO honesty-humility predicted dictator, but not generosity allocations, while traits capturing tendencies toward irritability and anger predicted lower generosity, but not dictator allocations. In contrast, the politeness-but not compassion-aspect of Big Five agreeableness was uniquely and broadly associated with prosociality across all games. These findings support the discriminant validity between related prosocial constructs, and have important implications for understanding the motives and mechanisms taking place within economic games.

    How do human beings decide when to be selfish or selfless? In this study, we gave testosterone to 25 men to establish its impact on prosocial behaviors in a double-blind within-subjects design. We also confirmed participants' testosterone levels before and after treatment through blood draws. Using the Ultimatum Game from behavioral economics, we find that men with artificially raised T, compared to themselves on placebo, were 27% less generous towards strangers with money they controlled (95% CI placebo: (1.70, 2.72); 95% CI T: (.98, 2.30)). This effect scales with a man's level of total-, free-, and dihydro-testosterone (DHT). Men in the lowest decile of DHT were 560% more generous than men in the highest decile of DHT. We also found that men with elevated testosterone were more likely to use their own money punish those who were ungenerous toward them. Our results continue to hold after controlling for altruism. We conclude that elevated testosterone causes men to behave antisocially.

    2009-01-01

    The authors present an interdependence theoretical framework and advance the argument that generosity serves the important purpose of communicating trust, which is assumed to be of utmost importance to coping with incidents of negative noise (i.e., when the other every now and then behaves less cooperatively than intended). Using a new social dilemma task (the parcel delivery paradigm), it was hypothesized that incidents of negative noise would exert detrimental effects on trust and trust-related judgments and experiences, as well as cooperation, and that relative to tit for tat and self-regarding strategies (stingy or unconditionally cooperative strategies), other-regarding strategies (i.e., unconditional cooperation and generosity) would be more effective at reducing such as detrimental effects. Results from 2 studies provided strong support for these hypotheses, suggesting that the power of generosity is underestimated in the extant literature, especially in its ability to maintain or build trust, which is essential for coping with noise.

  14. Charitable Sporting Events as a Context for Building Adolescent Generosity: Examining the Role of Religiousness and Spirituality

    Nathaniel A. Fernandez

    2016-03-01

    Full Text Available Previous research demonstrates an association between religiousness, spirituality, and generosity in adolescents, but few studies have tested the mechanisms by which religion might facilitate the development of generosity in real-world contexts. In this paper, a theoretical model is presented describing the potential mechanisms by which engagement in transformational contexts (i.e., participating in charity marathon training may lead to the development of generosity in adolescents. Participation in charity sporting events is theorized to increase generosity through both higher-order mechanisms, such as sanctification and the development of transcendent identity, and lower-order mechanisms, such as increased entitativity, positive emotions, and dissonance reduction. An empirical strategy for testing the model is presented; suggested methods for inquiry are longitudinal mixed method designs incorporating observations, questionnaires, and qualitative interviewing. Additionally, a case study of ongoing research on adolescents running with Team World Vision is described as an application of the model to an actual research context.

  15. Competition for trophies triggers male generosity.

    Directory of Open Access Journals (Sweden)

    Xiaofei Sophia Pan

    Full Text Available BACKGROUND: Cooperation is indispensable in human societies, and much progress has been made towards understanding human pro-social decisions. Formal incentives, such as punishment, are suggested as potential effective approaches despite the fact that punishment can crowd out intrinsic motives for cooperation and detrimentally impact efficiency. At the same time, evolutionary biologists have long recognized that cooperation, especially food sharing, is typically efficiently organized in groups living on wild foods, even absent formal economic incentives. Despite its evident importance, the source of this voluntary compliance remains largely uninformed. Drawing on costly signaling theory, and in light of the widely established competitive nature of males, we hypothesize that unique and displayable rewards (trophies out of competition may trigger male generosity in competitive social environments. PRINCIPAL FINDINGS: Here, we use a controlled laboratory experiment to show that cooperation is sustained in a generosity competition with trophy rewards, but breaks down in the same environment with equally valuable but non-unique and non-displayable rewards. Further, we find that males' competition for trophies is the driving force behind treatment differences. In contrast, it appears that female competitiveness is not modulated by trophy rewards. SIGNIFICANCE: Our results suggest new approaches to promoting cooperation in human groups that, unlike punishment mechanisms, do not sacrifice efficiency. This could have important implications in any domain where voluntary compliance matters--including relations between spouses, employers and employees, market transactions, and conformity to legal standards.

    Public generosity may be a means to convincingly advertise one's good character. This hypothesis suggests that altruistic individuals will be desirable as romantic partners. Few studies have tested this prediction, and these showed mixed results. Some studies have found that altruism is not particularly attractive; other studies showed that altruism is attractive by contrasting descriptions of 'nice guys' with 'jerks'. The present study sought to resolve this debate by having participants read a series of experimentally manipulated vignettes of persons with corresponding photographs, such that altruistic vignettes were compared with control descriptions that differed only in the presence or absence of small hints of altruistic tendencies. Altruists were more desirable for long-term relationships than neutral individuals. Women also preferred altruists for single dates whereas men had no such preference. These results are discussed with regard to the idea that people (males in particular) signal their good character via generosity.

    We assessed the impact of unemployment benefit programs on the health of the unemployed. We linked US state law data on maximum allowable unemployment benefit levels between 1985 and 2008 to individual self-rated health for heads of households in the Panel Study of Income Dynamics and implemented state and year fixed-effect models. Unemployment was associated with increased risk of reporting poor health among men in both linear probability (b=0.0794; 95% confidence interval [CI]=0.0623, 0.0965) and logistic models (odds ratio=2.777; 95% CI=2.294, 3.362), but this effect is lower when the generosity of state unemployment benefits is high (b for interaction between unemployment and benefits=-0.124; 95% CI=-0.197, -0.0523). A 63% increase in benefits completely offsets the impact of unemployment on self-reported health. Results suggest that unemployment benefits may significantly alleviate the adverse health effects of unemployment among men.

    2006-01-01

    Full Text Available In the present research, we analyse the role of generosity in the moral universe of childhood. We begin by defining generosity as a moral virtue, comparing it with justice. Then, we present a literature review of generosity-related psychological elements (ethics of care, pro-social attitudes, sympathy and establish the hypothesis that this virtue is better understood than justice by subjects who are six and nine years of age. To test this hypothesis, we present the results of two empirical studies with 6 and 9 year old children, in which we asked that they attribute feelings to people acting unjustly and ungenerously. While we confirm previous studies showing that six year olds have the tendency to attribute positive feelings to unjust people, the results show that negative feelings are attributed to ungenerous people. The discussion of this data defends the hypothesis according to which generosity, being less dependent of adult rules and impositions, has deeper roots than justice in the child's moral conscience.

    2015-06-01

    Full Text Available The purpose of this study was to examine the effect of peer monitoring on generosity in boys and girls aged 6 - 12 years. A total of 120 elementary school students played a one-shot dictator game (DG with and without peer monitoring by classmates. Children decided how to divide 10 chocolates between themselves and a classmate either in a condition in which their allocations were visible to their peers, or in private. While the effect of peer monitoring on the allocation amount in the DG was clearly present in boys, it was not observed in girls. Furthermore, the effect of peer monitoring in boys appeared at the age of 9 years. These results suggest that the motivation to draw peers’ attention plays a stronger role for older boys than for girls or younger boys. The potential roles of higher-order theory of mind, social roles, and emergence of secondary sex characteristics on the influence of peer monitoring on generosity shown by boys are discussed.

    Morality is an evolved aspect of human nature, yet is heavily influenced by cultural environment. This developmental study adopted an integrative approach by combining measures of socioeconomic status (SES), executive function, affective sharing, empathic concern, theory of mind, and moral judgment in predicting sharing behavior in children (N = 999) from the age of 5 to 12 in five large-scale societies: Canada, China, Turkey, South Africa, and the USA. Results demonstrate that age, gender, SES, culture, and social cognitive mechanisms explain over 20% of the variance worldwide in children's resource allocation. These findings are discussed in reference to standard cultural comparisons (individualist/collectivist), as well as the degree of market integration, and highlight continuities and discontinuities in children's generosity across urban contexts. © 2016 John Wiley & Sons Ltd.

  5. Showing Off in Humans: Male Generosity as a Mating Signal

    Directory of Open Access Journals (Sweden)

    Wendy Iredale

    2008-07-01

    Full Text Available We examined people's charity contributions while in the presence of an observer of the same sex, opposite sex, or no observer. Inspired by costly signaling theory, we hypothesized that men would be more generous in the presence of a potential mate. Men and women played a number of experimental games in which they could earn money. On completion of these games participants were asked what percentage of their earned money they would be willing to donate to charity. Our results show that men contribute more to charity when observed by a member of the opposite sex than by a member of the same sex or no observer. Conversely, female charity donations did not significantly vary across the three observer conditions. Findings support the notion that men's generosity might have evolved as a mating signal.

  6. The other side of the coin: Oxytocin decreases the adherence to fairness norms

    Full Text Available Oxytocin has been implicated in prosocial behaviors such as trust and generosity. Yet, these effects appear to strongly depend on characteristics of the situation and the people with whom we interact or make decisions. Norms and rules can facilitate and guide our actions, with fairness being a particularly salient and fundamental norm. The current study investigated the effects of intranasal oxytocin administration on fairness considerations in social decision-making in a double‐blind, placebo‐controlled within‐subject design. After having received 24 IU of oxytocin or placebo, participants completed a one‐shot Dictator Game and played the role of the responder in a modified version of the Ultimatum Game, in which an unfair offer of 8 coins for the proposer and 2 coins for the responder is paired with either a fair‐ (5:5 or no‐alternative (8:2. Rejection rates were higher when a fair alternative had been available than when there was no alternative to an unfair offer. Importantly, oxytocin did not de- or increase rejection rates overall, but reduced the sensitivity to contextual fairness, i.e. the context of alternatives in which an offer was made. As dictators, participants allocated less coins to the recipient when given oxytocin than when given placebo, indicating a decline in generosity. These results suggest that oxytocin decreases the adherence to fairness norms in social settings where others are likely to be perceived as not belonging to one’s ingroup. While our findings do not support the prosocial conception of oxytocin, they corroborate recent ideas that the effects of oxytocin are more nuanced than assumed in the past.

    We evaluate the effects of a reduction in the generosity of disability benefits in Spain that occurred in 2008. The main objective of the reform was to reduce the amount of benefits for individuals that do not have a long contributory history as the reform introduced a disincentive to apply to the system if the individual does not have 35 years of effective contributions. Theoretical insights are gained with a life-cycle model with heterogeneous disabled workers. The model's simulations predi...

    The aim of this study was to describe a comprehensive approach to decrease physical inactivity in the Veterans Health Administration (VHA) employee population. The approach included (1) initiatives to decrease physical inactivity in the workplace; (2) two operational surveys to assess system-wide service provision; and (3) two national employee surveys. From 2010 to 2012, 86 employee fitness centers were completed in VA medical centers. A grants program (2010 to 2015) funded smaller projects designed to decrease physical inactivity in the workplace. Projects involved the provision of equipment to decrease sedentary behaviors, including stability balls, treadmill and sit-to-stand desks, stairwell projects, and funding for on-site fitness classes, bicycle racks, and outdoor par courses and walking paths among others. A comprehensive approach to decrease physical inactivity in VHA employees was successful. Overall, self-reported, age-adjusted physical inactivity in VHA employees decreased from 25.3% in 2010 to 16.1% in 2015.

  9. Acute bouts of wheel running decrease cocaine self-administration: Influence of exercise output.

    Smith, Mark A; Fronk, Gaylen E; Zhang, Huailin; Magee, Charlotte P; Robinson, Andrea M

    Exercise is associated with lower rates of drug use in human populations and decreases drug self-administration in laboratory animals. Most of the existing literature examining the link between exercise and drug use has focused on chronic, long-term exercise, and very few studies have examined the link between exercise output (i.e., amount of exercise) and drug self-administration. The purpose of this study was to examine the effects of acute bouts of exercise on cocaine self-administration, and to determine whether these effects were dependent on exercise output and the time interval between exercise and drug self-administration. Female rats were trained to run in automated running wheels, implanted with intravenous catheters, and allowed to self-administer cocaine on a fixed ratio (FR1) schedule of reinforcement. Immediately prior to each test session, subjects engaged in acute bouts of exercise in which they ran for 0, 30, or 60min at 12m/min. Acute bouts of exercise before test sessions decreased cocaine self-administration in an output-dependent manner, with the greatest reduction in cocaine intake observed in the 60-min exercise condition. Exercise did not reduce cocaine self-administration when wheel running and test sessions were separated by 12h, and exercise did not reduce responding maintained by food or responding during a saline substitution test. These data indicate that acute bouts of exercise decrease cocaine self-administration in a time- and output-dependent manner. These results also add to a growing body of literature suggesting that physical activity may be an effective component of drug abuse treatment programs. Copyright © 2016 Elsevier Inc.

    Amanda L Sharpe

    Full Text Available Methamphetamine (METH is a psychostimulant that exhibits significant abuse potential. Although METH addiction is a major health and societal concern, no drug is currently approved for its therapeutic management. METH activates the central dopaminergic "reward" circuitry, and with repeated use increases levels of the neuromodulatory peptide neurotensin in the nucleus accumbens and ventral tegmental area. Previous studies in rats suggest that neurotensin agonism decreases METH self-administration, but these studies did not examine the effect of neurotensin agonism on the pattern of self-administration or open field locomotion. In our studies, we established intravenous METH self-administration in male, DBA/2J mice (fixed ratio 3, 2 hr sessions and examined the effect of pretreatment with the NTS1 receptor agonist PD149163 on METH self-administration behavior. Locomotion following PD149163 was also measured up to 2 hours after injection on a rotarod and in an open field. Pretreatment with PD149163 (0.05 and 0.10 mg/kg, s.c. significantly decreased METH self-administration. The pattern of responding suggested that PD149163 decreased motivation to self-administer METH initially in the session with more normal intake in the second hour of access. Voluntary movement in the open-field was significantly decreased by both 0.05 and 0.10 mg/kg (s.c. PD149163 from 10-120 minutes after injection, but rotarod performance suggested that PD149163 did not cause frank sedation. These results suggest that a systemically delivered NTS1 receptor agonist decreases METH self-administration in mice. The pattern of self-administration suggests that PD149163 may acutely decrease motivation to self-administer METH before the drug is experienced, but cannot rule out that depression of voluntary movement plays a role in the decreased self-administration.

    Full Text Available Chronic pain after cesarean section (CS is a serious concern, as it can result in functional disability. We evaluated the prevalence of chronic pain after CS prospectively at a single institution in Japan. We also analyzed perioperative risk factors associated with chronic pain using logistic regression analyses with a backward-stepwise procedure.Patients who underwent elective or emergency CS between May 2012 and May 2014 were recruited. Maternal demographics as well as details of surgery and anesthesia were recorded. An anesthesiologist visited the patients on postoperative day (POD 1 and 2, and assessed their pain with the Prince Henry Pain Scale. To evaluate the prevalence of chronic pain, we contacted patients by sending a questionnaire 3 months post-CS.Among 225 patients who questionnaires, 69 (30.7% of patients complained of persistent pain, although no patient required pain medication. Multivariate analyses identified lighter weight (p = 0.011 and non-intrathecal administration of morphine (p = 0.023 as determinant factors associated with persistent pain at 3 months. The adjusted odds ratio of intrathecal administration of morphine to reduce persistent pain was 0.424, suggesting that intrathecal administration of morphine could decrease chronic pain by 50%. In addition, 51.6% of patients had abnormal wound sensation, suggesting the development of neuropathic pain. Also, 6% of patients with abnormal wound sensation required medication, yet no patients with persistent pain required medication.Although no effect on acute pain was observed, intrathecal administration of morphine significantly decreased chronic pain after CS.

    Full Text Available No presente artigo, apresentamos uma análise do papel da generosidade no universo moral da criança. Começamos por definir a generosidade enquanto virtude moral, comparando-a com a justiça. Em seguida, fazemos uma revisão da literatura psicológica que nos traz dados sobre elementos relacionados a ela (ética do cuidado, atitudes pró-sociais e simpatia e apresentamos a hipótese segundo a qual a generosidade é melhor assimilada do que a justiça por parte de crianças de 6 anos. Para testar esta hipótese, apresentamos os resultados de 2 pesquisas com crianças de 6 e 9 anos, nas quais pedimo-lhes que atribuem sentimentos a personagens não justas e não generosas. Coerentemente com resultados de estudos anteriores, a maioria das crianças de 6 anos atribui sentimentos positivos à personagem não justa. Em compensação, elas atribuem sentimentos negativos às personagens não generosas. Estes dados são discutidos para defender a hipótese segundo a qual a generosidade, por ser menos dependente de regras e imposições adultas, tem raízes mais profundas do que a justiça na consciência moral infantil.In the present research, we analyse the role of generosity in the moral universe of childhood. We begin by defining generosity as a moral virtue, comparing it with justice. Then, we present a literature review of generosity-related psychological elements (ethics of care, pro-social attitudes, sympathy and establish the hypothesis that this virtue is better understood than justice by subjects who are six and nine years of age. To test this hypothesis, we present the results of two empirical studies with 6 and 9 year old children, in which we asked that they attribute feelings to people acting unjustly and ungenerously. While we confirm previous studies showing that six year olds have the tendency to attribute positive feelings to unjust people, the results show that negative feelings are attributed to ungenerous people.

    Full Text Available The paper analyzes the growing tendency for young people’s harden- ing. According to the authors that phenomenon is caused by such current trends as the language degradation, the militaristic and alienation vocabulary predominance re- sulting in disdainful attitude towards the surrounding people. As a pedagogic counter- action to such trends, the authors consider the revival of the forgotten domestic moral values in educational sphere. Their objective is to contemplate the necessity of enrich- ing the educational institutions by means of the national moral and cultural potential.The research methodology basis is defined as the axiology principle substantiat- ing the humanistic importance of the specifics of teachers’ vocabulary. To demonstrate the advantages of the humanistic vocabulary educational potential the authors com- pare the specifics of such notions as generosity and tolerance. They prove that the teacher’s tolerant attitude to students deforms both the pedagogic theory and educa- tional practice. In contrast, the generous attitude favors the student’s, as well as teacher’s moral development. The process of the youth refinement can be facilitated by the large-scale revival of half-forgotten national humanistic values and the vocabulary reflecting such values. 

  15. Abraham Trembley's strategy of generosity and the scope of celebrity in the mid-eighteenth century.

    2004-12-01

    Historians of science have long believed that Abraham Trembley's celebrity and impact were attributable chiefly to the incredible regenerative phenomena demonstrated by the polyp, which he discovered in 1744, and to the new experimental method he devised to investigate them. This essay shows that experimental method alone cannot account for Trembley's success and influence; nor are the marvels of the polyp sufficient to explain its scientific and cultural impact. Experimental method was but one element in a new conception of the laboratory that called for both experimental and para-experimental skills whose public availability depended on a new style of communication. The strategy of generosity that led Trembley to dispatch polyps everywhere enabled experimental naturalist laboratories to spread throughout Europe, and the free circulation of living objects for scientific research led practitioners to establish an experimental field distinct from mechanical physics. Scholars reacted to the marvels of the polyp by strengthening the boundaries between the public and academic spheres and, in consequence, opened a space for new standards in both scientific work and the production of celebrity.

    Given that cannabis use is increasing in the United States, pharmacological treatment options to treat cannabis use disorder are needed. Opioid antagonists modulate cannabinoid effects and may offer a potential approach to reducing cannabis use. In this double-blind, placebo-controlled human laboratory study, we assessed the effects of naltrexone maintenance on the reinforcing, subjective, psychomotor, and cardiovascular effects of active and inactive cannabis. Nontreatment-seeking, daily cannabis smokers were randomized to receive naltrexone (50 mg: n=18 M and 5 F) or placebo (0 mg; n=26 M and 2 F) capsules for 16 days. Before, during, and after medication maintenance, participants completed 10 laboratory sessions over 4–6 weeks, assessing cannabis' behavioral and cardiovascular effects. Medication compliance was verified by observed capsule administration, plasma naltrexone, and urinary riboflavin. Relative to placebo, maintenance on naltrexone significantly reduced both active cannabis self-administration and its positive subjective effects (‘good effect'). Participants in the placebo group had 7.6 times (95% CI: 1.1–51.8) the odds of self-administering active cannabis compared with the naltrexone group. This attenuation of reinforcing and positive subjective effects also influenced cannabis use in the natural ecology. Naltrexone had intrinsic effects: decreasing ratings of friendliness, food intake, and systolic blood pressure, and increasing spontaneous reports of stomach upset and headache, yet dropout rates were comparable between groups. In summary, we show for the first time that maintenance on naltrexone decreased cannabis self-administration and ratings of ‘good effect' in nontreatment-seeking daily cannabis smokers. Clinical studies in patients motivated to reduce their cannabis use are warranted to evaluate naltrexone's efficacy as a treatment for cannabis use disorder. PMID:25881117

    Oxytocin (OT) plays a critical role in the formation of long lasting social attachments across a range of mammalian species. Raising intracerebral OT levels by intranasal administration of the neuropeptide (inOT) can also have pronounced effects on human sociocognitive functioning. inOT has been associated with increasing altruism, generosity, empathy and trust while decreasing fear, anxiety and stress reactions via neural mechanisms which are yet to be fully elucidated. The observation of the prosocial effects of OT has led to speculation about the role the peptide might play in some psychiatric conditions and debate as to its potential therapeutic uses. Here we note the great similarity in the sociocognitive effects that can be induced by inOT and the effects of acute consumption of modest does of alcohol. We further reflect on how both compounds may act on limbic and prefrontal cortical structures to increase GABAergic transmission, thereby facilitating the release of prepotent responses, that is, more automatic responses which are associated with earlier developmental stages.

    2013-09-01

    Full Text Available Objective: To evaluate behavioral changes and brain-derived neurotrophic factor (BDNF levels in rats subjected to ketamine administration (25 mg/kg for 7 days. Method: Behavioral evaluation was undertaken at 1 and 6 hours after the last injection. Results: We observed hyperlocomotion 1 hour after the last injection and a decrease in locomotion after 6 hours. Immobility time was decreased and climbing time was increased 6 hours after the last injection. BDNF levels were decreased in the prefrontal cortex and amygdala when rats were killed 6 hours after the last injection, compared to the saline group and to rats killed 1 hour after the last injection. BDNF levels in the striatum were decreased in rats killed 6 hours after the last ketamine injection, and BDNF levels in the hippocampus were decreased in the groups that were killed 1 and 6 hours after the last injection. Conclusion: These results suggest that the effects of ketamine on behavior and BDNF levels are related to the time at which they were evaluated after administration of the drug.

    People's tendency to be more generous toward identifiable victims than toward unidentifiable or statistical victims is known as the Identifiable Victim Effect. Recent research has called the generality of this effect into question, showing that in cross-national contexts, identifiability mostly affects willingness to help victims of one's own "in-group." Furthermore, in inter-group conflict situations, identifiability increased generosity toward a member of the adversary group, but decreased generosity toward a member of one's own group. In the present research we examine the role of group-cohesiveness as an underlying factor accounting for these divergent findings. In particular, we examined novel groups generated in the lab, using the minimal group paradigm, as well as natural groups of students in regular exercise sections. Allocation decisions in dictator games revealed that a group's cohesiveness affects generosity toward in-group and out-group recipients differently, depending on their identifiability. In particular, in cohesive groups the identification of an in-group recipient decreased, rather than increased generosity.

    Isocaloric protein undernutrition is associated with decreased bone mass and decreased bone strength, together with lower IGF-I levels. It remains unclear whether administration of growth hormone (GH) corrects these alterations in bone metabolism. Six-month-old female rats were fed isocaloric diets containing either 2.5% or 15% casein for 2 weeks. Bovine growth hormone (bGH, 0.5 or 2.5mg/kg of body weight) or vehicle was then administered as subcutaneous injections, twice daily, to rats on either diet for 4 weeks. At the proximal tibia, analysis of bone mineral density (BMD), maximal load and histomorphometry were performed. In addition, urinary deoxypyridinoline, plasma osteocalcin and IGF-I concentrations were measured. Weight was monitored weekly. bGH caused a dose-dependent increase in plasma IGF-I regardless of the dietary protein content. However, bGH dose-dependently decreased BMD and bone strength in rats fed the low-protein diet. There was no significant effect of bGH on BMD in rats fed the normal protein diet within this short-term treatment period, however bone formation as detected by histomorphometry was improved in this group but not the low-protein group. Osteoclast surface was increased in the low-protein bGH-treated animals only. Changes in bone turnover markers were detectable under both normal and low-protein diets. These results emphasize the major importance of dietary protein intake in the bone response to short-term GH administration, and highlight the need for further investigation into the effects of GH treatment in patients with reduced protein intake.

    Aberrations in protein folding, processing, and/or degradation are common features of neurodegenerative diseases, such as Alzheimer's disease (AD). Sodium 4-phenylbutyrate (PBA) is a well-known histone deacetylase inhibitor, which increases gene transcription of a number of genes, and also exerts neuroprotective effects. PBA acts as a chemical chaperone reducing the load of mutant or unfolded proteins during cellular stress. Previously, we reported that 5-week administration of PBA reinstated memory loss and dendritic spine densities in the Tg2576 mouse model of AD. In this study we reported that chronic administration of PBA, starting before the onset of disease symptoms (6 month-old) prevents age-related memory deficits in Tg2576 mice. The amelioration of the memory impairment is associated to a decrease in amyloid beta pathology and the glial fibrillary acidic protein (GFAP), suggesting that inflammation was reduced in PBA-treated animals. Together, the beneficial effects of PBA make it a promising agent for the prevention of AD.

    People can get most of their needs broadly satisfied in two ways: by close communal ties and by dealings with people in the marketplace. These modes of relating-termed communal and market-often necessitate qualitatively different motives, behaviors, and mind-sets. We reasoned that activating market mode would produce behaviors consistent with it and impair behaviors consistent with communal mode. In a series of experiments, money-the market-mode cue-was presented to Polish children ages 3 to 6. We measured communal behavior by prosocial helpfulness and generosity and measured market behavior by performance and effort. Results showed that handling money (compared with other objects) increased laborious effort and reduced helpfulness and generosity. The effects of money primes were not due to the children's mood, liking for money, or task engagement. This work is the first to demonstrate that young children tacitly understand market mode and also understand that money is a cue to shift into it. © The Author(s) 2016.

    In rodents, weight reduction after peptide YY[3-36] (PYY[3-36]) administration may be due largely to decreased food consumption. Effects on other processes affecting energy balance (energy expenditure, fuel partitioning, gut nutrient uptake) remain poorly understood. We examined whether s.c. infusion of 1 mg/(kg x d) PYY[3-36] (for up to 7 d) increased metabolic rate, fat combustion, and/or fecal energy loss in obese mice fed a high-fat diet. PYY[3-36] transiently reduced food intake (e.g., 25-43% lower at d 2 relative to pretreatment baseline) and decreased body weight (e.g., 9-10% reduction at d 2 vs. baseline) in 3 separate studies. Mass-specific metabolic rate in kJ/(kg x h) in PYY[3-36]-treated mice did not differ from controls. The dark cycle respiratory quotient (RQ) was transiently decreased. On d 2, it was 0.747 +/- 0.008 compared with 0.786 +/- 0.004 for controls (P light cycle RQ was reduced throughout the study in PYY[3-36]-treated mice (0.730 +/- 0.006) compared with controls (0.750 +/- 0.009; P energy loss was negligible ( approximately 2% of ingested energy) and did not differ between PYY[3-36]-treated mice and controls. Thus, negative energy balance after PYY[3-36] administration in diet-induced obese mice results from reduced food intake with a relative maintenance of mass-specific energy expenditure. Fat loss and reduced RQ highlight the potential for PYY[3-36] to drive increased mobilization of fat stores to help meet energy requirements in this model.

    Full Text Available Objectives Banha-sasim-tang (BST, which consists of seven different herbs, is one of the most popular herbal formulae for treating gastrointestinal disorders in Eastern Asia. The commonly used herbal medicine is often co-administered with other therapeutic drugs, which raises the possibility of herb–drug interactions and may modify the clinical safety profile of therapeutic drugs. Methods We investigated the potential herb–drug interactions between BST extract and midazolam (MDZ in mice. The area under the plasma concentration-time curve (AUC of MDZ and 1ʹ-hydroxymidazolam (1ʹ-OH-MDZ was evaluated for both oral and intraperitoneal administration of MDZ, following oral administration of BST (0.5 and 1 g/kg. Results It was found that the AUC of MDZ and 1ʹ-OH-MDZ was lower in case of oral administration of MDZ. Administration of BST extract was not associated with hepatic cytochrome P450 activity. BST extract induced a strong reduction in pH and it has been reported that oral mucosal absorption of MDZ is lower at low pH. The decreased absorption rate of MDZ might be caused by the ingredients of BST and may not be related to other factors such as increased excretion of MDZ by P-glycoprotein. Conclusions The altered pharmacokinetics of midazolam caused by co-administration with BST in vivo could be attributed to a decrease in pH and subsequent reduction of MDZ absorption rate.

    Full Text Available OBJECTIVE: The present study aims to investigate the effects of ouabain intracerebroventricular injection on BDNF levels in the amygdala and hippocampus of Wistar rats. METHODS: Animals received a single intracerebroventricular injection of ouabain (10-3 and 10-2 M or artificial cerebrospinal fluid and immediately, 1h, 24h, or seven days after injection, BDNF levels were measured in the rat's amygdala and hippocampus by sandwich-ELISA (n = 8 animals per group. RESULTS: When evaluated immediately, 3h, or 24h after injection, ouabain in doses of 10-2 and 10-3 M does not alter BDNF levels in the amygdala and hippocampus. However, when evaluated seven days after injection, ouabain in 10-2 and 10-3 M, showed a significant reduction in BDNF levels in both brain regions evaluated. DISCUSSION: In conclusion, we propose that the ouabain decreased BDNF levels in the hippocampus and amygdala when assessed seven days after administration, supporting the Na/K ATPase hypothesis for bipolar illness.

    To determine whether continuous administration of nitrous oxide and remifentanil—either alone or together—alters blood flow in oral tissues during sevoflurane anesthesia. Eight male tracheotomized Japanese white rabbits were anesthetized with sevoflurane under mechanical ventilation. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), common carotid arterial blood flow (CCBF), tongue mucosal blood flow (TMBF), mandibular bone marrow blood flow (BBF), masseter muscle blood flow (MBF), upper alveolar tissue blood flow (UBF), and lower alveolar tissue blood flow (LBF) were recorded in the absence of all test agents and after administration of the test agents (50 % nitrous oxide, 0.4 μg/kg/min remifentanil, and their combination) for 20 min. Nitrous oxide increased SBP, DBP, MAP, CCBF, BBF, MBF, UBF, and LBF relative to baseline values but did not affect HR or TMBF. Remifentanil decreased all hemodynamic variables except DBP. Combined administration of nitrous oxide and remifentanil recovered SBP, DBP, MAP, and CCBF to baseline levels, but HR and oral tissue blood flow remained lower than control values. Our findings suggest that concomitant administration of nitrous oxide and remifentanil reduces blood flow in oral tissues without decreasing blood pressure during sevoflurane anesthesia in rabbits.

    Full Text Available The highlights of a study of the 4-H Record Book (RB in light of the four positive youth development (PYD concepts: belonging, mastery, independence, and generosity are discussed in this paper. Utilizing qualitative methods we interviewed 21 participants (14 leaders, 9 recent 4-H alumni from 9 states. Results describe the ways in which participants perceived that the RB (a supports the four PYD concepts (e.g., “RB fosters independence through the goal setting, monitoring, and appraising process” and (b does not support, or should be revised to support the concept (e.g., “RB competitions may hinder mastery”. Our results support the RB as a PYD intervention but we recommend that states/counties consider these results when revising RBs. In light of concerns about age and developmental appropriateness, we suggest that the most pressing question is whether or not the traditionally formatted RB is appropriate for all 4-Hers. We encourage RB committees to engage professionals with developmental expertise (e.g., educators in RB revisions.

    Full Text Available The reactive oxygen species (ROS are known to play a major role in many pathophysiological conditions, such as ischemia and reperfusion injury. The present study was aimed to evaluate the in vivo cyanidin (anthocyanin effects on damages induced by rat pial microvascular hypoperfusion-reperfusion injury by cerebral blood flow decrease (CBFD and subsequent cerebral blood flow recovery (CBFR. In particular, the main purpose was to detect changes in ROS production after cyanidin administration. Rat pial microvasculature was investigated using fluorescence microscopy through a cranial window (closed; Strahler's method was utilized to define the geometric features of pial vessels. ROS production was investigated in vivo by 2′-7′-dichlorofluorescein-diacetate assay and neuronal damage was measured on isolated brain sections by 2,3,5-triphenyltetrazolium chloride staining. After 30 min of CBFD, induced by bilateral common carotid artery occlusion, and 60 min of CBFR, rats showed decrease of arteriolar diameter and capillary perfusion; furthermore, increase in microvascular leakage and leukocyte adhesion was observed. Conversely, cyanidin administration induced dose-related arteriolar dilation, reduction in microvascular permeability as well as leukocyte adhesion when compared to animals subjected to restriction of cerebral blood flow; moreover, capillary perfusion was protected. ROS generation increase and marked neuronal damage were detected in animals subjected to CBFD and CBFR. On the other hand, cyanidin was able to reduce ROS generation and neuronal damage. In conclusion, cyanidin treatment showed dose-related protective effects on rat pial microcirculation during CBFD and subsequent CBFR, inducing arteriolar dilation by nitric oxide release and inhibiting ROS formation, consequently preserving the blood brain barrier integrity.

    This study sought to answer the question, "Can police officers administer intranasal naloxone to drug overdose victims to decrease the opioid overdose death rate?" This prospective interventional study was conducted in Lorain County, OH, from January 2011 to October 2014. Starting October 2013, trained police officers administered naloxone to suspected opioid overdose victims through a police officer naloxone prescription program (NPP). Those found by the county coroner to be positive for opioids at the time of death and those who received naloxone from police officers were included in this study. The rate of change in the total number of opioid-related deaths in Lorain County per quarter year, before and after initiation of the NPP, and the trend in the survival rate of overdose victims who were given naloxone were analyzed by linear regression. Significance was established a priori at P police officer NPP with average deaths per quarter of 5.5 for 2011, 15.3 for 2012, and 16.3 for the first 9 months of 2013. After initiation of the police officer NPP, the number of opioid overdose deaths decreased each quarter with an overall average of 13.4. Of the 67 participants who received naloxone by police officers, 52 (77.6%) survived, and 8 (11.9%) were lost to follow-up. Intranasal naloxone administration by police first responders is associated with decreased deaths in opioid overdose victims. Copyright © 2015 Elsevier Inc. All rights reserved.

    People often exhibit prosocial tendencies towards close kin and friends, but generosity decreases as a function of increasing social distance between donor and recipient, a phenomenon called social discounting. Evidence suggests that acute stress affects prosocial behaviour in general and social discounting in particular. We tested the causal role of the important stress neuromodulators cortisol (CORT) and noradrenaline (NA) in this effect by considering two competing hypotheses. On the one hand, it is possible that CORT and NA act in concert to increase generosity towards socially close others by reducing the aversiveness of the cost component in costly altruism and enhancing the emotional salience of vicarious reward. Alternatively, it is equally plausible that CORT and NA exert dissociable, opposing effects on prosocial behaviour based on prior findings implicating CORT in social affiliation, and NA in aggressive and antagonistic tendencies. We pharmacologically manipulated CORT and NA levels in a sample of men (N = 150) and found that isolated hydrocortisone administration promoted prosocial tendencies towards close others, reflected in an altered social discount function, but this effect was offset by concurrent noradrenergic activation brought about by simultaneous yohimbine administration. These results provide inceptive evidence for causal, opposing roles of these two important stress neuromodulators on prosocial behaviour, and give rise to the possibility that, depending on the neuroendocrine response profile, stress neuromodulator action can foster both tend-and-befriend and fight-or-flight tendencies at the same time.

    To determine if intestinal alkaline phosphatase (IAP) decreases intestinal injury resulting from experimentally induced necrotizing enterocolitis (NEC). We hypothesized that IAP administration prevents the initial development of NEC related intestinal inflammation. Pre- and full-term newborn Sprague-Dawley rat pups were sacrificed on day 1 of life. Pre-term pups were exposed to intermittent hypoxia and formula containing LPS to induce NEC. Select NEC pups were given 40, 4 or 0.4 units/kg of bovine IAP (NEC+IAP40u, IAP4u or IAP0.4u) enterally, once daily. Ileal sections were evaluated by real-time PCR (qRT-PCR) for IAP, iNOS, IL-1β, IL-6, and TNF-α mRNA and immunofluorescence for 3-nitrotyrosine (3-NT). Experimentally induced NEC decreased IAP mRNA expression by 66% (p ≤ 0.001). IAP supplementation increased IAP mRNA expression to control. Supplemental enteral IAP decreased nitrosative stress as measured by iNOS mRNA expression and 3-NT staining in the NEC stressed pups (p ≤ 0.01), as well as decreased intestinal TNF-α mRNA expression. In addition, IAP decreased LSP translocation into the serum in the treated pups. We conclude that enterally administered IAP prevents NEC-related intestinal injury and inflammation. Enteral IAP may prove a useful strategy in the prevention of NEC in preterm neonates. Copyright © 2013 Elsevier Inc. All rights reserved.

    To investigate the effect of diet, physical exercise and sibutramine administration on serum anti-Müllerian hormone (AMH) levels, hormonal and metabolic parameters in overweight and obese patients with polycystic ovary syndrome (PCOS). Prospective clinical study, in an outpatient clinic setting, of 76 overweight and obese women with PCOS. All patients were placed on a hypocaloric diet, physical exercise plus sibutramine (10 mg per day) for the first month and then on either a hypocaloric diet, physical exercise plus sibutramine (10 mg per day) or a hypocaloric diet and physical exercise for the subsequent 6 months. Serum AMH levels, body composition, hormonal and metabolic features and insulin sensitivity indices were evaluated at baseline and at 4 and 7 months of treatment. Body weight reduction was greater in the sibutramine group. Moreover, serum FSH and testosterone levels decreased, and SHBG, free androgen index and all indices of insulin resistance significantly improved at 4 and 7 months. Serum AMH levels decreased only in PCOS women who received sibutramine, at both 4 and 7 months of treatment. A hypocaloric diet and a diet plus sibutramine both resulted in significant weight loss in overweight and obese women with PCOS. Patients who received sibutramine showed greater weight loss and improvement in hyperandrogenemia and insulin sensitivity after 7 months of treatment. Serum AMH levels significantly decreased at both 4 and 7 months of treatment only in PCOS women who received sibutramine, indicating a possible direct, gonadotropin independent effect of sibutramine on the ovarian production of AMH.

    By investigating the neurochemical mechanisms through which alcohol activates the brain reward systems, novel treatment strategies for alcohol use disorder (AUD), a chronic relapsing disease, can be developed. In contrast to the common view of the function of gut-brain peptides, such as neuromedin U (NMU), to regulate food intake and appetite, a novel role in reinforcement mediation has been implied. The anorexigenic effects of NMU are mediated via NMU2 receptors, preferably in the arcuate nucleus and paraventricular nucleus. The expression of NMU2 receptors is also expressed in several reward-related areas in the brain, suggesting a role in reward regulation. The present experiments were therefore set up to investigate the effect of intracerebroventricular administration of NMU on alcohol-mediated behaviors in rodents. We found that central administration of NMU attenuated alcohol-induced locomotor stimulation, accumbal dopamine release and the expression of conditioned place preference in mice. In addition, NMU dose dependently decreased alcohol intake in high, but not in low, alcohol-consuming rats. Central NMU administration did not alter the blood alcohol concentrations nor change the corticosterone levels in rodents. Given that AUD is a major health-care challenge causing an enormous cost to society and novel treatment strategies are warranted, our data suggest that NMU analogues deserve to be evaluated as novel treatment of AUD in humans. © 2016 The Authors Addiction Biology published by John Wiley & Sons Ltd.

    Aging is a multifactorial universal process and constitutes the most important risk factor for chronic-degenerative diseases. Although it is a natural process, pathological aging arises when these changes occur quickly and the body is not able to adapt. This is often associated with the generation of reactive oxygen species (ROS), inflammation, and a decrease in the endogenous antioxidant systems, constituting a physiopathological state commonly found in chronic-degenerative diseases. At the testicular level, aging is associated with tissue atrophy, decreased steroidogenesis and spermatogenesis, and sexual behavior disorders. This situation, in addition to the elevated generation of ROS in the testicular steroidogenesis, provides a critical cellular environment causing oxidative damage at diverse cellular levels. To assess the effects of a reduction in the levels of ROS, thiamine pyrophosphate (TPP) was chronically administered in senile Wistar rats. TPP causes an activation of intermediate metabolism routes, enhancing cellular respiration and decreasing the generation of ROS. Our results show an overall decrease of atrophic histological changes linked to aging, with higher levels of serum testosterone, sexual activity, and an increase in the levels of endogenous antioxidant enzymes in TPP-treated animals. These results suggest that TPP chronic administration decreases the progression of age-related atrophic changes by improving the intermediate metabolism, and by increasing the levels of antioxidant enzymes.

    We examined the effects of an adenosine receptor agonist on caffeine-induced changes in thermoregulation, neurotransmitter release in the preoptic area and anterior hypothalamus, and endurance exercise performance in rats. One hour before the start of exercise, rats were intraperitoneally injected with either saline alone (SAL), 10 mg kg(-1) caffeine and saline (CAF), a non-selective adenosine receptor agonist (5'-N-ethylcarboxamidoadenosine [NECA]: 0.5 mg kg(-1)) and saline (NECA), or the combination of caffeine and NECA (CAF+NECA). Rats ran until fatigue on the treadmill with a 5% grade at a speed of 18 m min(-1) at 23 °C. Compared to the SAL group, the run time to fatigue (RTTF) was significantly increased by 52% following caffeine administration and significantly decreased by 65% following NECA injection (SAL: 91 ± 14.1 min; CAF: 137 ± 25.8 min; NECA: 31 ± 13.7 min; CAF+NECA: 85 ± 11.8 min; pcaffeine injection inhibited the NECA-induced decreases in the RTTF, Tcore, heat production, heat loss, and extracellular DA release. Neither caffeine nor NECA affected extracellular noradrenaline or serotonin release. These results support the findings of previous studies showing improved endurance performance and overrides in body limitations after caffeine administration, and imply that the ergogenic effects of caffeine may be associated with the adenosine receptor blockade-induced increases in brain DA release.

    Full Text Available Obesity can lead to skeletal muscle atrophy, a pathological condition characterized by the loss of strength and muscle mass. A feature of muscle atrophy is a decrease of myofibrillar proteins as a result of ubiquitin proteasome pathway overactivation, as evidenced by increased expression of the muscle-specific ubiquitin ligases atrogin-1 and MuRF-1. Additionally, other mechanisms are related to muscle wasting, including oxidative stress, myonuclear apoptosis, and autophagy. Stem cells are an emerging therapy in the treatment of chronic diseases such as high fat diet-induced obesity. Mesenchymal stem cells (MSCs are a population of self-renewable and undifferentiated cells present in the bone marrow and other mesenchymal tissues of adult individuals. The present study is the first to analyze the effects of systemic MSC administration on high fat diet-induced skeletal muscle atrophy in the tibialis anterior of mice. Treatment with MSCs reduced losses of muscle strength and mass, decreases of fiber diameter and myosin heavy chain protein levels, and fiber type transitions. Underlying these antiatrophic effects, MSC administration also decreased ubiquitin proteasome pathway activation, oxidative stress, and myonuclear apoptosis. These results are the first to indicate that systemically administered MSCs could prevent muscle wasting associated with high fat diet-induced obesity and diabetes.

    Estimated prevalence of canine idiopathic epilepsy is 0.6 per cent in the first-opinion canine population in the UK. Phenobarbital monotherapy has been reported to reduce/eradicate seizure activity in 60-93 per cent of idiopathic epileptic dogs (IEDs). The objective of this study was to evaluate safety and efficacy of the administration of phenobarbital orally every eight hours in IEDs with phenobarbital elimination half-life less than 20 hours. Medical records of 10 IEDs in which steady state trough serum phenobarbital levels were within the reference range and phenobarbital elimination half-life had become less than 20 hours following prolonged administration every 12 hours were reviewed. Side effects and seizure frequency when phenobarbital was administered every 12 hours or 8 hours were compared. In all dogs the side effects of the antiepileptic medication treatment improved. When phenobarbital was administered every eight hours, 9/10 dogs experienced improvement in seizure frequency and 8/10 dogs maintained seizure freedom for a period three times longer than the longest interictal interval period previously recorded. Reduction in the severity and number of clusters of seizures was recorded in one of the remaining two dogs. The administration of phenobarbital orally every eight hours in IEDs with decreased phenobarbital elimination half-life appears safe and can improve seizure management. The results of this study were presented in abstract form (poster) for the 28th symposium of the European Society of Veterinary Neurology - European College of Veterinary Neurology (ESVN), September 18-19, 2015, Amsterdam, Netherlands.

    Full Text Available Abstract Exogenous administration of insulin-like growth factor (IGF-I has anti-depressant properties in rodent models of depression. However, nothing is known about the anti-depressant properties of IGF-I during inflammation, nor have mechanisms by which IGF-I alters behavior following activation of the innate immune system been clarified. We hypothesized that central IGF-I would diminish depressive-like behavior on a background of an inflammatory response and that it would do so by inducing expression of the brain-derived neurotrophic factor (BDNF while decreasing pro-inflammatory cytokine expression in the brain. IGF-I (1,000 ng was administered intracerebroventricularly (i.c.v. to CD-1 mice. Mice were subsequently given lipopolysaccharide i.c.v. (LPS, 10 ng. Sickness and depressive-like behaviors were assessed followed by analysis of brain steady state mRNA expression. Central LPS elicited typical transient signs of sickness of mice, including body weight loss, reduced feed intake and decreased social exploration toward a novel juvenile. Similarly, LPS increased time of immobility in the tail suspension test (TST. Pretreatment with IGF-I or antidepressants significantly decreased duration of immobility in the TST in both the absence and presence of LPS. To elucidate the mechanisms underlying the anti-depressant action of IGF-I, we quantified steady-state mRNA expression of inflammatory mediators in whole brain using real-time RT-PCR. LPS increased, whereas IGF-I decreased, expression of inflammatory markers interleukin-1ß (IL-1ß, tumor necrosis factor-(TNFα, inducible nitric oxide synthase (iNOS and glial fibrillary acidic protein (GFAP. Moreover, IGF-I increased expression of BDNF. These results indicate that IGF-I down regulates glial activation and induces expression of an endogenous growth factor that shares anti-depressant activity. These actions of IGF-I parallel its ability to diminish depressive-like behavior.

    This study reports the effects of oral Aloe vera gel powder (AVGP) containing Aloe sterols on skin elasticity and the extracellular matrix in ultraviolet B (UVB)-irradiated hairless mice. Ten-week-old hairless mice were fed diets containing 0.3% AVGP for 8 weeks and irradiated UVB for 6 weeks. Mice treated with AVGP showed significant prevention of the UVB-induced decrease in skin elasticity. To investigate the mechanism underlying this suppression of skin elasticity loss, we measured the expression of matrix metalloproteinase (MMP)-2, -9, and -13. AVGP prevented both the UVB-induced increases in MMPs expressions. Moreover, we investigated hyaluronic acid (HA) content of mice dorsal skin and gene expression of HA synthase-2 (Has2). In the results, AVGP oral administration prevented UVB-induced decreasing in skin HA content and Has2 expression and attenuates the UVB-induced decrease in serum adiponectin, which promotes Has2 expression. These results suggested that AVGP has the ability to prevent the skin photoaging.

    An experimental study of the hypoglycemic action of polymeric derivatives of insulin was carried out by its enteral administration through a gastric tube into the stomach and into the oral cavity on 105 intract rabbits. A marked hypoglycemic effect significantly differing from the action of crystalline insulin was produced by enteral administration of insulin modified with polymeres. Changes in the character of binding of the protein with the polymere, of the molecular weight of the polymere and of its chemical nature proved to influence the value and the duration of action of insulin modified by polymeres.

  6. Social Discounting under Risk.

    As a measure of how prosocial behavior depends on social distance, social discounting is defined as the decrease in generosity between the decision maker and the recipient as the social distance increases. While risk is a ubiquitous part of modern life, there is limited research on the relationship between risk and prosocial behavior. In the present experiment, we empirically test whether risk has an influence on social discounting. We use the choice titration procedure to examine this effect. Our data show that independent of risk, participants are less eager to forego money and exhibit more selfishness toward a specific person when the social distance increases; these findings are reflected in the hyperbolic model. Interestingly, risk influences the shape of the social discounting function, which is reflected in the notable different discount rates. Individuals who make decisions under risk yield a smaller discount rate than those who make decisions without risk, i.e., under risk subjects reduce less their generosity as a function of the social distance. Furthermore, this distinct type of generosity occurs typically among individuals with 10-distance recipients but not with the closest- and furthest-social-distance recipients.

    People tend to become more generous as they grow older, which may reflect an increase in their ego-transcending motives (i.e., concern more for the benefit of recipients than of the benefactors). The current study aimed to examine evidence for an enhanced ego-transcending motive among older adults. We adapted the social-discounting framework to quantify generosity toward people of different social distances, ranging from socially close others (e.g., family and close friends) to socially distant others (e.g., total strangers), in both young and older adults. We hypothesized that the normative decrease in generosity as a function of social distance (e.g., less generous towards strangers compared to close friends) will be mitigated in older adults. Our results supported that older adults were more generous toward socially distant others (i.e., less social discounting) compared to younger adults. Thus, consistent with the idea that the elderly are more oriented to ego-transcending goals, older adults are generous even when their generosity is unlikely to be reciprocated. © The Author 2017.

Six normal, healthy adult Barbari bucks (25-30 Kg aged between 2 to 2.5 years were used as semen donors. The bucks were administered enrofloxacin at the dose of 5mg/kg body weight intra-muscularly daily for 7 days. From each buck biweekly eighteen semen ejaculates (1st to 18th were collected and one sample (0th from each buck was collected before administration of enrofloxacin, using a non-oestrous doe as dummy and investigated for semen quality parameters. There was no significant difference (P≥0.05 in seminal volume between different ejaculates. Mass motility decreased significantly (P≤0.01 and was lowest in 4th ejaculate as compared to mass motility prior to drug administration. Highest significant (P≤0.01 decrease in progressive motility was seen in 9th ejaculate as compared to progressive motility before drug administration. Sperm concentration decreased significantly (P≤0.01 and was found to be lowest in 4th ejaculate as compared to sperm concentration before enrofloxacin administration. Percent live spermatozoa decreased significantly (P≤0.01 and was found to be minmum in 12th ejaculate as compared to sperm concentration prior to drug administration. Highest significant increase (P≤ 0.01 in per cent head, mid-piece and tail abnormalities of spermatozoa was observed in 4th, 3rd and 6th ejaculate respectively following parentral administration of enrofloxacion as compared to ejaculate before drug administration. Following drug administration, the semen quality decreased progressively and then became slowly normal after 14th ejaculate.

    In an attempt to obviate the necessity for hospitalisation, the ablative dose of {sup 131}I in the treatment of thyroid cancer is divided into two or three fractions at weekly intervals in some hospitals with no special bed for {sup 131}I treatment. Thyroid stunning has been observed in patients receiving a {sup 131}I dose between 74 and 370 MBq (2-10 mCi). However, the influence of {sup 131}I uptake after administration of a higher dose, such as 1,110-1,850 MBq of {sup 131}I, has never been reported. In this study, we evaluated the degree of reduction in {sup 131}I uptake after patients received 1,480 MBq of {sup 131}I and evaluated the clinical value of fractionated ablative doses of {sup 131}I. Thirty-five patients with functional thyroid cancer received a total of 4,440 MBq (120 mCi) of {sup 131}I which was divided into three fractions administered at weekly intervals. In all patients two {sup 131}I whole-body scans were performed. The first scan was performed directly prior to the second dose of {sup 131}I (7 days after the first administration of {sup 131}I), and the second scan was performed 7 days after the second administration of {sup 131}I and directly prior to the third administration. Regions of interest including the neck and lungs were drawn to calculate the uptake of {sup 131}I in the thyroid remnant and possible cervical lymph node and lung metastases. The mean uptake of {sup 131}I was 2.73% 7 days after the first administration, and decreased significantly to 0.26% 7 days after the second administration. The mean decrease was as high as 80.7%. The decrease in {sup 131}I uptake was significant in all patients except the two with lung metastases. In the two patients with lung metastases, no definite evidence of decreased uptake was noted; the uptake of {sup 131}I in the lung metastases even increased on the second {sup 131}I image in one of these patients. After administration of 1,480 MBq of {sup 131}I, the decreased uptake was significant in all

    Supplementation of intestinal alkaline phosphatase (IAP), an endogenous protein expressed in the intestines, decreases the severity of necrotizing enterocolitis (NEC)-associated intestinal injury and permeability. We hypothesized that IAP administration is protective in a dose-dependent manner of the inflammatory response in a neonatal rat model. Pre- and full-term newborn Sprague-Dawley rat pups were sacrificed on day of life 3. Control pups were vaginally delivered and dam fed. Preterm pups were delivered via cesarean section and exposed to intermittent hypoxia and formula feeds containing lipopolysaccharide (NEC) with and without IAP. Three different standardized doses were administered to a group of pups treated with 40, 4, and 0.4U/kg of bovine IAP (NEC+IAP40, IAP4, or IAP0.4U). Reverse transcription-real-time polymerase chain reaction (RT-PCR) for inducible nitric oxide synthase (iNOS) and tumor necrosis factor (TNF)-α on liver and lung tissues and serum cytokine analysis for interleukin (IL)-1β, IL-6, IL-10, and TNF-α were performed. Data were analyzed by Kruskal-Wallis and Mann-Whitney tests, expressed as mean±standard error of the mean and P≤0.05 considered significant. Levels of cytokines IL-1β, IL-6, and TNF-α increased significantly in NEC versus control, returning to control levels with increasing doses of supplemental enteral IAP. Hepatic and pulmonary TNF-α and iNOS messenger ribonucleic acid expressions increased in NEC, and the remaining elevated despite IAP supplementation. Proinflammatory cytokine expression is increased systemically with intestinal NEC injury. Administration of IAP significantly reduces systemic proinflammatory cytokine expression in a dose-dependent manner. Early supplemental enteral IAP may reduce NEC-related injury and be useful for reducing effects caused by a proinflammatory cascade. Copyright © 2012 Elsevier Inc. All rights reserved.

    Feeding behavior is complex processes controlled by the neruroendocrine system.5-HT play an important role in regulation of energy balance by suppressing food intake. Depletion of brain serotonin increase feeding behavior and develop obesity. Many serotoninergic compounds are available in market for the management of body weight. 02-Lean is an anti-obesity herbal formulation prepared by combination of different herbs. Oral administration of aqueous suspension of 02-Lean caused a significant decrease in body weight, food intake, and increase in whole brain 5-HT 5HIAA, tryptophan and plasma tryptophan in over weight rats treated with 0.096g/2ml 02-Lean in comparison to control group.

    Perinatal phencyclidine (PCP) administration in rat blocks the N-methyl D-aspartate receptor (NMDAR) and causes symptoms reminiscent of schizophrenia in human. A growing body of evidence suggests that alterations in γ-aminobutyric acid (GABA) interneuron neurotransmission may be associated with schizophrenia. Neuregulin-1 (NRG-1) is a trophic factor important for neurodevelopment, synaptic plasticity, and wiring of GABA circuits. The aim of this study was to determine the long-term effects of perinatal PCP administration on the projection and local circuit neurons and NRG-1 expression in the cortex and hippocampus. Rats were treated on postnatal day 2 (P2), P6, P9, and P12 with either PCP (10 mg/kg) or saline. Morphological studies and determination of NRG-1 expression were performed at P70. We demonstrate reduced densities of principal neurons in the CA3 and dentate gyrus (DG) subregions of the hippocampus and a reduction of major interneuronal populations in all cortical and hippocampal regions studied in PCP-treated rats compared with controls. For the first time, we show the reduced density of reelin- and somatostatin-positive cells in the cortex and hippocampus of animals perinatally treated with PCP. Furthermore, an increase in the numbers of perisomatic inhibitory terminals around the principal cells was observed in the motor cortex and DG. We also show that perinatal PCP administration leads to an increased NRG-1 expression in the cortex and hippocampus. Taken together, our findings demonstrate that perinatal PCP administration increases NRG-1 expression and reduces the number of projecting and local circuit neurons, revealing complex consequences of NMDAR blockade.

    Lipofuscin is an autofluorescent and undegradable material, which accumulates in tissues during ageing and under different types of stress. Among these, oxidative stress represents a major trigger for lipofuscin formation. However, prolonged noise exposure is also an effective stressful stimuli. Diazepam may inhibit lipofuscinogenesis in liver and prevent the noise-induced reduction of the steroidogenesis in the adrenal gland. The aim of the study was to ascertain whether chronic noise exposure causes lipofuscin accumulation in mouse testis, and to evaluate the effects of diazepam administration. Eight-week old mice were either exposed for 6 weeks (6 h day(-1)) to white-noise (group A), or received diazepam (3 mg kg(-1), i.p.) before noise exposures (group B), while a further group was used as control (group C). Light fluorescence and transmission electron microscopy revealed lipofuscin in large amounts in the Leydig cells in mice of group A, which concomitantly had low serum testosterone levels; pre-treatment with diazepam occluded both effects. The present study indicates that: (i) chronic noise exposure causes lipofuscin accumulation at the level of the Leydig cells and a decrease in testosterone; (ii) all these effects are suppressed by pre-treatment with diazepam. As the Leydig cells represent the only cellular type of the interstitial testicular tissue having peripheral benzodiazepine receptors, these results could be explained by the capacity of the peripheral benzodiazepine receptors to prevent reactive oxygen species damage and to increase the resistance of these cells to oxidative stress.

    Full Text Available Selling, general and administration costs are the main components in the Income Statement. A large number of permanent staff in sales and marketing department will make the company dominated by the fixed costs. This fact could lead to sticky cost behavior. In addition, role of the manager can also cause the cost stickiness. When the company’s revenue decreases, manager may delay to decrease the cost or not even decrease cost at all. The objective of the study is to determine whether cost stickiness of selling, general and administrative in the Indonesian listed companies. This study applied log-linear data panel regression with 3605 firm years that is listed in Indonesian Stock Exchange (BEI from 1993 – 2013. This study finds that selling, general, and administrative costs are sticky only for the manufacturing companies. Furthermore, the results show that adjustment of sales, general, and administrative costs delayed by the manager when revenue decreases, yet the cost stickiness will be reduced in the next period.

  18. Give what you get: capuchin monkeys (Cebus apella and 4-year-old children pay forward positive and negative outcomes to conspecifics.

    Directory of Open Access Journals (Sweden)

    Kristin L Leimgruber

    Full Text Available The breadth of human generosity is unparalleled in the natural world, and much research has explored the mechanisms underlying and motivating human prosocial behavior. Recent work has focused on the spread of prosocial behavior within groups through paying-it-forward, a case of human prosociality in which a recipient of generosity pays a good deed forward to a third individual, rather than back to the original source of generosity. While research shows that human adults do indeed pay forward generosity, little is known about the origins of this behavior. Here, we show that both capuchin monkeys (Cebus apella and 4-year-old children pay forward positive and negative outcomes in an identical testing paradigm. These results suggest that a cognitively simple mechanism present early in phylogeny and ontogeny leads to paying forward positive, as well as negative, outcomes.

    To describe the hemodynamic changes that occur with sodium bicarbonate (NaHCO 3 ) administration in premature neonates. This retrospective study included premature neonates 23 to 31+6 weeks of gestational age who underwent continuous cardiac and cerebral monitoring as participants in prospective trials at our institution, and who received NaHCO 3 infused over 30 min in the first 24 h of life. Blood pressure (BP), heart rate, cardiac output (CO), SpO 2 and cerebral oximetry (StO 2 ) were captured every 2 s. A baseline was established for all continuous data and averaged over the 10 min before NaHCO 3 administration. Baseline was compared with measurements over 10 min epochs until 80 min after administration. Arterial blood gases before and within 1 h of administration were also compared. Significance was set at P<0.05. A total of 36 subjects received NaHCO 3 (1.3±0.3 mEq kg -1 ) in the first 24 h (14±8.5 h) of life. NaHCO 3 administration increased pH (7.23 vs 7.28, P<0.01) and decreased base deficit (-8.9 vs -6.8, P<0.01) and PaCO 2 (45 vs 43 mm Hg, P<0.05). There was a transient but significant (P<0.05) decrease in systemic BP coinciding with an increase in cerebral oxygenation without an increase in oxygen extraction. CO did not change. Early postnatal NaHCO 3 administration does not acutely improve CO but does cause transient fluctuations in cerebral and cardiovascular hemodynamics in extremely premature infants.

  20. Regulation of glutamate transporter 1 (GLT-1) gene expression by cocaine self-administration and withdrawal.

    Downregulation of the astroglial glutamate transporter GLT-1 is observed in the nucleus accumbens (NAc) following administration of multiple drugs of abuse. The decrease in GLT-1 protein expression following cocaine self-administration is dependent on both the amount of cocaine self-administered and the length of withdrawal, with longer access to cocaine and longer withdrawal periods leading to greater decreases in GLT-1 protein. However, the mechanism(s) by which cocaine downregulates GLT-1 protein remains unknown. We used qRT-PCR to examine gene expression of GLT-1 splice isoforms (GLT-1A, GLT-1B) in the NAc, prelimbic cortex (PL) and basolateral amygdala (BLA) of rats, following two widely used models of cocaine self-administration: short-access (ShA) self-administration, and the long-access (LgA) self-administration/incubation model. While downregulation of GLT-1 protein is observed following ShA cocaine self-administration and extinction, this model did not lead to a change in GLT-1A or GLT-1B gene expression in any brain region examined. Forced abstinence following ShA cocaine self-administration also was without effect. In contrast, LgA cocaine self-administration and prolonged abstinence significantly decreased GLT-1A gene expression in the NAc and BLA, and significantly decreased GLT-1B gene expression in the PL. No change was observed in NAc GLT-1A gene expression one day after LgA cocaine self-administration, indicating withdrawal-induced decreases in GLT-1A mRNA. In addition, LgA cocaine self-administration and withdrawal induced hypermethylation of the GLT-1 gene in the NAc. These results indicate that a decrease in NAc GLT-1 mRNA is only observed after extended access to cocaine combined with protracted abstinence, and that epigenetic mechanisms likely contribute to this effect.

    Acute exposure to ±3,4-methylenedioxymethamphetamine (MDMA) preferentially increases release of serotonin (5-HT), and a role of 5-HT in many of the behavioral effects of acute exposure to MDMA has been demonstrated. A role of 5-HT in MDMA self-administration in rats has not, however, been adequately determined. Therefore, the present study measured the effect of pharmacological manipulation of some 5-HT receptor subtypes on self-administration of MDMA. Rats received extensive experience with self-administered MDMA prior to tests with 5-HT ligands. Doses of the 5-HT1A antagonist, WAY 100635 (0.1-1.0mg/kg), 5-HT1B antagonist, GR 127935 (1.0-3.0mg/kg), and the 5-HT2A antagonist, ketanserin (1.0-3.0mg/kg) that have previously been shown to decrease self-administration of other psychostimulants and that decreased MDMA-produced hyperactivity in the present study did not alter MDMA self-administration. Experimenter-administered injections of MDMA (10.0mg/kg, ip) reinstated extinguished drug-taking behavior, but this also was not decreased by any of the antagonists. In contrast, both WAY 100635 and ketanserin, but not GR 127935, decreased cocaine-produced drug seeking in rats that had been trained to self-administered cocaine. The 5-HT1A agonist, 8-OH-DPAT (0.1-1.0mg/kg), but not the 5-HT1B/1A agonist, RU 24969 (0.3-3.0mg/kg), decreased drug-seeking produced by the reintroduction of a light stimulus that had been paired with self-administered MDMA infusions. These findings suggest a limited role of activation of 5-HT1A, 5-HT1B or 5-HT2 receptor mechanisms in MDMA self-administration or in MDMA-produced drug-seeking following extinction. The data suggest, however, that 5-HT1A agonists inhibit cue-induced drug-seeking following extinction of MDMA self-administration and might, therefore, be useful adjuncts to therapies to limit relapse to MDMA use.

    Our previous study showed that quercetin enhances the anticancer effect of trichostatin A (TSA) in xenograft mice given quercetin intraperitoneally (10 mg/kg, 3 times/week). Herein, we investigate whether quercetin administered orally exerts such an effect and prevents the cytotoxic side effects of TSA. We found that quercetin given orally (20 and 100 mg/kg, 3 times/week) failed to enhance the antitumor effect of TSA although it increased the total quercetin concentration more than quercetin administered intraperitoneally in the plasma. The compound quercetin-3-glucuronide (Q3G) increased the most. However, quercetin administered intraperitoneally increased the total quercetin level in tumor tissues more than oral quercetin. Oral and intraperitoneal administration of quercetin similarly decreased lymphocyte DNA damage and plasma lipid peroxidation level induced by TSA. Furthermore, we found that the enhancing effect of Q3G on the antitumor effect of TSA and the incorporation of Q3G was less than that of quercetin in A549 cells. However, we found that A549 cells possessed the ability to convert Q3G to quercetin. In conclusion, different from quercetin administered intraperitoneally, quercetin administered orally failed to enhance the antitumor effect of TSA because of its metabolic conversion. However, it prevented TSA-induced DNA damage and lipid peroxidation.

    Little is known regarding the relationship between social evaluation-induced neuroendocrine responses and generosity in game-theoretic situations. Previous studies demonstrated that reputation formation plays a pivotal role in prosocial behavior. This study aimed to examine the relationships between a social evaluation-induced salivary alpha-amylase (sAA) response and generosity in the dictator game. The relationship is potentially important in neuroeconomics of altruism and game theory. We assessed sAA and allocated money in the dictator game in male students with and without social evaluation. RESULTS Social evaluation-responders allocated significantly more money than controls; while there was no significant correlation between social evaluation-induced sAA elevation and the allocated money. Social evaluation significantly increases generosity in the dictator game, and individual differences in trait characteristics such as altruism and reward sensitivity may be important determinants of generosity in the dictator game task.

  5. Is catalase involved in the effects of systemic and pVTA administration of 4-methylpyrazole on ethanol self-administration?

    The oxidative metabolism of ethanol into acetaldehyde involves several enzymes, including alcohol dehydrogenase (ADH) and catalase-hydrogen peroxide (H 2 O 2 ). In this regard, while it is well known that 4-methylpyrazole (4-MP) acts by inhibiting ADH in the liver, little attention has been placed on its ability to interfere with fatty acid oxidation-mediated generation of H 2 O 2 , a mechanism that may indirectly affect catalase whose enzymatic activity requires H 2 O 2 . The aim of our investigation was twofold: 1) to evaluate the effect of systemic (i.p. [intraperitoneal]) and local (into the posterior ventral tegmental area, pVTA) administration of 4-MP on oral ethanol self-administration, and 2) to assess ex vivo whether or not systemic 4-MP affects liver and brain H 2 O 2 availability. The results show that systemic 4-MP reduced ethanol but not acetaldehyde or saccharin self-administration, and decreased the ethanol deprivation effect. Moreover, local intra-pVTA administration of 4-MP reduced ethanol but not saccharin self-administration. In addition, although unable to affect basal catalase activity, systemic administration of 4-MP decreased H 2 O 2 availability both in liver and in brain. Overall, these results indicate that 4-MP interferes with ethanol self-administration and suggest that its behavioral effects could be due to a decline in catalase-H 2 O 2 system activity as a result of a reduction of H 2 O 2 availability, thus highlighting the role of central catalase-mediated metabolism of ethanol and further supporting the key role of acetaldehyde in the reinforcing properties of ethanol.

    1990-04-01

    A dosage regimen of lysergic acid diethylamide (LSD) that reliably produces behavioral tolerance in rats was evaluated for effects on neurotransmitter receptor binding in rat brain using a variety of radioligands selective for amine receptor subtypes. Daily administration of LSD [130 micrograms/kg (0.27 mumol/kg) intraperitoneally (IP)] for 5 days produced a decrease in serotonin2 (5-hydroxytryptamine2, 5-HT2) binding in cortex (measured 24 hours after the last drug administration) but did not affect binding to other receptor systems (5-HT1A, 5-HT1B, beta-adrenergic, alpha 1- or alpha 2-adrenergic, D2-dopaminergic) or to a recognition site for 5-HT uptake. The decrease was evident within 3 days of LSD administration but was not demonstrable after the first LSD dose. Following 5 days of LSD administration the decrease was still present 48 hours, but not 96 hours, after the last administration. The indole hallucinogen psilocybin [1.0 mg/kg (3.5 mumol/kg) for 8 days] also produced a significant decrease in 5HT2 binding, but neither the nonhallucinogenic analog bromo-LSD [1.3 mg/kg (2.4 mumol/kg) for 5 days] nor mescaline [10 mg/kg (40.3 mumol/kg) for 5 or 10 days] affected 5-HT2 binding. These observations suggest that LSD and other indole hallucinogens may act as 5-HT2 agonists at postsynaptic 5-HT2 receptors. Decreased 5-HT2 binding strikingly parallels the development and loss of behavioral tolerance seen with repeated LSD administration, but the decreased binding per se cannot explain the gamut of behavioral tolerance and cross-tolerance phenomena among the indole and phenylethylamine hallucinogens.

    Full Text Available Naftopidil, an α1-adrenoceptor antagonist, has been shown to inhibit nocturnal polyuria in patients with lower urinary tract symptom. However, it remains unclear how naftopidil decreases nocturnal urine production. Here, we investigated the effects of naftopidil on arginine-vasopressin (AVP plasma level and urine production and osmolality in rats centrally administered with noradrenaline (NA. NA (3 or 30 μg/kg was administered into the left ventricle (i.c.v. of male Wistar rats 3 h after naftopidil pretreatment (10 or 30 mg/kg, i.p.. Blood samples were collected from the inferior vena cava 1 h after NA administration or 4 h after peritoneal administration of naftopidil; plasma levels of AVP were assessed by ELISA. Voiding behaviors of naftopidil (30 mg/kg, i.p.-administered male Wistar rats were observed during separate light- and dark cycles. Administration of NA decreased plasma AVP levels and elevated urine volume, which were suppressed by systemic pretreatment with naftopidil (30 mg/kg, i.p.. Urine osmolality decreased 1 h after NA administration. However, naftopidil by itself had no effect on plasma AVP levels or urodynamic parameters during light- and dark cycles. Our findings suggest that systemic administration of naftopidil could prevent central noradrenergic nervous system-mediated decline in AVP secretion and increase in urine production in rats.

    L-Kynurenine (L-KYN) is a central metabolite of tryptophan degradation through the kynurenine pathway (KP). The systemic administration of L-KYN sulfate (L-KYNs) leads to a rapid elevation of the neuroactive KP metabolite kynurenic acid (KYNA). An elevated level of KYNA may have multiple effects on the synaptic transmission, resulting in complex behavioral changes, such as hypoactivity or spatial working memory deficits. These results emerged from studies that focused on rats, after low-dose L-KYNs treatment. However, in several studies neuroprotection was achieved through the administration of high-dose L-KYNs. In the present study, our aim was to investigate whether the systemic administration of a high dose of L-KYNs (300 mg/bwkg; i.p.) would produce alterations in behavioral tasks (open field or object recognition) in C57Bl/6j mice. To evaluate the changes in neuronal activity after L-KYNs treatment, in a separate group of animals we estimated c-Fos expression levels in the corresponding subcortical brain areas. The L-KYNs treatment did not affect the general ambulatory activity of C57Bl/6j mice, whereas it altered their moving patterns, elevating the movement velocity and resting time. Additionally, it seemed to increase anxiety-like behavior, as peripheral zone preference of the open field arena emerged and the rearing activity was attenuated. The treatment also completely abolished the formation of object recognition memory and resulted in decreases in the number of c-Fos-immunopositive-cells in the dorsal part of the striatum and in the CA1 pyramidal cell layer of the hippocampus. We conclude that a single exposure to L-KYNs leads to behavioral disturbances, which might be related to the altered basal c-Fos protein expression in C57Bl/6j mice.

    This study evaluates whether emergency department septic shock patients without a fever (reported or measured) receive less IV fluids, have decreased antibiotic administration, and suffer increased in-hospital mortality. This was a secondary analysis of a prospective, observational study of patients with shock. The study was conducted in an urban, academic emergency department. The original study enrolled consecutive adult (aged 18 yr or older) emergency department patients from November 11, 2012, to September 23, 2013, who met one of the following shock criteria: 1) systolic blood pressure less than 90 mm Hg after at least 1L IV fluids, 2) new vasopressor requirement, or 3) systolic blood pressure less than 90 mm Hg and IV fluids held for concern of fluid overload. The current study is limited to patients with septic shock. Patients were grouped as febrile if they had a subjective fever or a measured temperature >100.4°F documented in the emergency department; afebrile patients lacked both. Among 378 patients with septic shock, 207 of 378 (55%; 50-60%) were febrile by history or measurement. Afebrile patients had lower rates of antibiotic administration in the emergency department (81% vs 94%; p < 0.01), lower mean volumes of IV fluids (2,607 vs 3,013 mL; p < 0.01), and higher in-hospital mortality rates (33% vs 11%; p < 0.01). After adjusting for bicarbonate less than 20 mEq/L, lactate concentration, respiratory rate greater than or equal to 24 breaths/min, emergency department antibiotics, and emergency department IV fluids volume, being afebrile remained a significant predictor of in-hospital mortality (odds ratio, 4.3; 95% CI, 2.2-8.2; area under the curve = 0.83). In emergency department patients with septic shock, afebrile patients received lower rates of emergency department antibiotic administration, lower mean IV fluids volume, and suffered higher in-hospital mortality.

    The aims of this study were to analyze the administrative trends in U.S. dental schools at the beginning and end of a thirteen-year period and to identify the predictive factors for those changes. Administrative trends were measured by the difference in the number of major administrative positions for 1997 and 2010 reported in American Dental Education Association (ADEA) and American Dental Association (ADA) publications. Secondary measures (program length, student enrollment, and tuition) were also gathered. The mean numbers of administrative positions per school significantly increased over the study period, while the mean number of clinical science departments per school significantly decreased. The change in the number of directors was positively correlated with the change in student enrollment, but inversely correlated with the change in number of vice/associate/assistant deans. The change in the number of clinical science departments was positively correlated with changes in student enrollment and out-of-state tuition, but inversely correlated with the change in in-state tuition. The number of all departments per U.S. dental school significantly decreased in this period. The schools that had consolidation of clinical science departments were less likely to have increases in student enrollment and out-of-state tuition, but more likely to have increases in in-state tuition.

    In this study, we question (1) whether the relationship between unemployment and mental healthcare use, controlling for mental health status, varies across European countries and (2) whether these differences are patterned by a combination of unemployment and healthcare generosity. We hypothesize that medicalization of unemployment is stronger in countries where a low level of unemployment generosity is combined with a high level of healthcare generosity. A subsample of 36,306 working-age respondents from rounds 64.4 (2005-2006) and 73.2 (2010) of the cross-national survey Eurobarometer was used. Country-specific logistic regression and multilevel analyses, controlling for public disability spending, changes in government spending, economic capacity, and unemployment rate, were performed. We find that unemployment is medicalized, at least to some degree, in the majority of the 24 nations surveyed. Moreover, the medicalization of unemployment varies substantially across countries, corresponding to the combination of the level of unemployment and of healthcare generosity.

    Recent scholarship offers different theories on how macrosocial determinants affect the population health of East and Southeast Asian nations. Dominant theories emphasize the effects of welfare regimes, welfare generosity, and labor market institutions. In this article, we conduct exploratory time-series cross-sectional analyses to generate new evidence on these theories while advancing a political explanation. Using unbalanced data of 7 East Asian countries and 11 Southeast Asian nations from 1960 to 2012, primary findings are 3-fold. First, welfare generosity measured as education and health spending has a positive impact on life expectancy, net of GDP. Second, life expectancy varies significantly by labor markets; however, these differences are explained by differences in welfare generosity. Third, as East and Southeast Asian countries become more democratic, welfare generosity increases, and population health improves. This study provides new evidence on the value of considering politics, welfare states, and labor markets within the same conceptual framework. © 2016 APJPH.

    Despite its centrality to contemporary inequality, working poverty is often popularly discussed but rarely studied by sociologists. Using the Luxembourg Income Study (2009), we analyze whether an individual is working poor across 18 affluent democracies circa 2000. We demonstrate that working poverty does not simply mirror overall poverty and that there is greater cross-national variation in working than overall poverty. We then examine four explanations for working poverty: demographic characteristics, economic performance, unified theory, and welfare generosity. We utilize Heckman probit models to jointly model the likelihood of employment and poverty among the employed. Our analyses provide the least support for the economic performance explanation. There is modest support for unified theory as unionization reduces working poverty in some models. However, most of these effects appear to be mediated by welfare generosity. More substantial evidence exists for the demographic characteristics and welfare generosity explanations. An individual's likelihood of being working poor can be explained by (a) a lack of multiple earners or other adults in one's household, low education, single motherhood, having children and youth; and (b) the generosity of the welfare state in which he or she resides. Also, welfare generosity does not undermine employment and reduces working poverty even among demographically vulnerable groups. Ultimately, we encourage a greater role for the welfare state in debates about working poverty.

    Female rats were given 1 μCi per g body weight of 32 P intraperitoneally four or eight times at intervals of two weeks, and half the rats received ovariectomy after two weeks. Various damages in the rats which received ovariectomy were compared with those in rats which did not receive ovariectomy. As to a change of body weight, an increase of body weight observed through the whole observation term after desexualization (for 11 months after the administration) was inhibited, and there was not any difference between ovariectomized and not-ovariectomized rats. The number of leukocytes decreased just after the administration. It took one month and a half in 4 times administration and three months and a half in 8 times administration to recover the number of leukocytes to normal values. There was no effect of desexualization. On the group administered 32 P 8 times the number of erythrocytes tended to decrease markely, but it recovered to a normal condition rapidly after the finish of the administration. As to onset of tumors, osteosarcoma occurred with high incidence (63%) regardless of presence of desexualization and frequency of the administration. The incidence of leukemia was about 15%. One case of breast tumor was recognized in nonovariectomized rats. Malignant tumors were not recognized in cases with normal sexual cycle for 8 to 10 months after the beginning of the administration.

    The purpose of this study was to examine the effects of voluntary wheel running on the positive reinforcing effects of heroin in rats with an established history of drug self-administration. Rats were assigned to sedentary (no wheel) and exercise (wheel) conditions and trained to self-administer cocaine under positive reinforcement contingencies. Rats acquiring cocaine self-administration were then tested with various doses of heroin during daily test sessions. Sedentary rats self-administered more heroin than exercising rats, and this effect was greatest at low and moderate doses of heroin. These data suggest that voluntary wheel running decreases the positive reinforcing effects of heroin.

    The InBox messaging system is an internal, electronic program used at Mayo Clinic, Rochester, MN, to facilitate the sending, receiving, and answering of patient-specific messages and alerts. A standardized InBox was implemented in the Division of General Internal Medicine to decrease the time physicians, physician assistants, and nurse practitioners (clinicians) spend on administrative tasks and to increase efficiency. Clinicians completed surveys and a preintervention InBox pilot test to determine inefficiencies related to administrative burdens and defects (message entry errors). Results were analyzed using Pareto diagrams, value stream mapping, and root cause analysis to prioritize administrative-burden inefficiencies to develop a new, standardized InBox. Clinicians and allied health staff were the target of this intervention and received standardized InBox training followed by a postintervention pilot test for clinicians. Sixteen of 28 individuals (57%) completed the preintervention survey. Twenty-eight clinicians participated in 2 separate 8-day pilot tests (before and after intervention) for the standardized InBox. The number of InBox defects was substantially reduced from 37 (Pilot 1) to 7 (Pilot 2). Frequent InBox defects decreased from 25% to 10%. More than half of clinicians believed the standardized InBox positively affected their work, and 100% of clinicians reported no negative affect on their work. This project demonstrated the successful implementation of the standardized InBox messaging system. Initial assessments show substantial reduction of InBox entry defects and administrative tasks completed by clinicians. The findings of this project suggest increased clinician and allied health staff efficiency, satisfaction, improved clinician work-life balance, and decreased clinician burden caused by administrative tasks.

    Oxytocin, an octapeptide synthesized in the hypothalamus, stimulates milk election and uterine contractions. In the brain this hormone acts as a neuropeptide. It could inhibit through the GABAergic system the activity of limbic amygdala, which is involved in the response to fear. Oxytocin could also induce the protective behaviour of the mother towards its offspring through the dopaminergic system. In mankind, oxytocin plays a role in trust, empathy, generosity, stress and sexuality. Clinical studies are testing potential benefits of oxytocin administration in autism, depression and social phobia. Results are still preliminary.

    Male Wistar rats were injected with CdCl 2 subcutaneously to examine in vivo effects of Cd on density and survival of red blood cells. During the 7 days after administration of 1.0 mg Cd/kg, the following sequence of events occurred: (1) a progressive increase in the amount of more dense red blood cells concomitant with a decrease in that of light red blood cells from the first to the third day; (2) an increase in the spleen weight at the third day; (3) a decrease in the hematocrit value and an increase in the amount of light red blood cells at the fifth day; and (4) a recovery of the hematocrit value at the seventh day. Five days after administration, the hematocrit value decreased in a dose-dependent mode and the decrease was significant at the 1% level at 1.0 and 1.5 mg Cd/kg. A highly significant splenomegaly was also observed at 0.5 to 1.5 mg Cd/kg. In order to label red blood cells in vivo, [ 3 H] diisopropylfluorophosphate ([ 3 H]DFP) was injected into rats. At Day 11, Cd at either 0.5 or 1.0 mg/kg was administered to [ 3 H]DFP-prelabeled animals. Cd administration accelerated 3 H-labeled red cell clearance from the blood. Six days after Cd administration, the radioactivity of red blood cells was 76 and 68% of the control at 0.5 and 1.0 mg Cd/kg, respectively. In vitro treatment of rat red density and accelerated in vivo clearance of red blood cells from the recipient circulation. These results show that Cd at low dose can cause anemia by increasing red cell density and by accelerating red cell sequestration, presumably in the spleen

    A single dose of 40 μg/kg bodyweight (BW) of oromucosal detomidine gel was administered sublingually to 10 healthy Dutch Warmblood mares aged 7 ± 4 years (mean ± SD) and BW 580 ± 69 kg. Blood and urine samples were collected before and for 8 days following administration and evaluated qualitatively in an FEI Reference Laboratory and quantitatively in a research laboratory. Clinical effects were evaluated at baseline and for 24 h after administration. Sedation was determined using head height and scores of reaction to auditory and mixed auditory/sensory stimuli. Mechanical nociceptive thresholds (MNTs) were assessed using pressure algometry to evaluate analgesia. Heart rate (HR) was measured and ataxia scored. All horses were considered negative for detomidine in blood samples by 48 h post-administration and in urine by 60 h. These results indicated that a safe withdrawal time for detomidine oromucosal gel may be 72 h following a single sublingual administration of 40 μg/kgBW. Decreases in HR and head height were maximal at 40 and 60 min post-administration, respectively. The maximal decrease in response to stimuli was observed at 100 min. Ataxia was maximal at 60 min. At 40 and 80 min MNTs were significantly increased compared to baseline. All parameters, except the MNTs of two locations, which were decreased, returned to baseline values within 24 h post-administration. Copyright © 2012 Elsevier Ltd. All rights reserved.

    2016-08-01

    Endogenous levels of the neurosteroid (NS) allopregnanolone (AlloP) during neonatal stages are crucial for the correct development of the central nervous system (CNS). In a recent work we reported that the neonatal administration of AlloP or finasteride (Finas), an inhibitor of the enzyme 5α-reductase needed for AlloP synthesis, altered the voluntary consumption of ethanol and the ventrostriatal dopamine (DA) levels in adulthood, suggesting that neonatal NS manipulations can increase alcohol abuse vulnerability in adulthood. Moreover, other authors have associated neonatal NS alterations with diverse dopaminergic (DAergic) alterations. Thus, the aim of the present work is to analyse if manipulations of neonatal AlloP alter the DAergic response in the nucleus accumbens (NAcc) during alcohol intake in rats. We administered AlloP or Finas from postnatal day (PND) 5 to PND9. At PND98, we measured alcohol consumption using a two-bottle free-choice model (ethanol 10% (v/v)+glucose 3% (w/v), and glucose 3% (w/v)) for 12 days. On the last day of consumption, we measured the DA and 3,4-dihydroxyphenylacetic acid (DOPAC) release in NAcc in response to ethanol intake. The samples were obtained by means of in vivo microdialysis in freely moving rats, and DA and DOPAC levels were determined by means of high-performance liquid chromatography analysis (HPLC). The results revealed that neonatal Finas increased ethanol consumption in some days of the consumption phase, and decreased the DA release in the NAcc in response to solutions (ethanol+glucose) and food presentation. Taken together, these results suggest that neonatal NS alterations can affect alcohol rewarding properties. Copyright © 2016 Elsevier B.V. All rights reserved.

    BACKGROUND: The role of noradrenergic system in the control of nociception is documented in some vertebrate animals. However, there are no data showing the role of this system on nociception in the marsh terrapins. METHODOLOGY: In this study, the antinociceptive action of intrathecal administration...... of the α 2-adrenoreceptor agonist clonidine and α 2-adrenoreceptor antagonist yohimbine was evaluated in the African marsh terrapin using the formalin test. The interaction of clonidine and yohimbine was also evaluated. RESULTS: Intrathecal administration of clonidine (37.5 or 65 μg/kg) caused...... a significant reduction in the mean time spent in pain-related behavior. Yohimbine, at a dose of 25 μg/kg, significantly blocked the effect of clonidine (65 μg/kg). However, administration of yohimbine (40 or 53 μg/kg) caused a significant reduction in the mean time spent in pain-related behavior. Intrathecal...

    Awe is an emotional response to perceptually vast stimuli that transcend current frames of reference. Guided by conceptual analyses of awe as a collective emotion, across 5 studies (N = 2,078) we tested the hypothesis that awe can result in a diminishment of the individual self and its concerns, and increase prosocial behavior. In a representative national sample (Study 1), dispositional tendencies to experience awe predicted greater generosity in an economic game above and beyond other prosocial emotions (e.g., compassion). In follow-up experiments, inductions of awe (relative to various control states) increased ethical decision-making (Study 2), generosity (Study 3), and prosocial values (Study 4). Finally, a naturalistic induction of awe in which participants stood in a grove of towering trees enhanced prosocial helping behavior and decreased entitlement compared to participants in a control condition (Study 5). Mediational data demonstrate that the effects of awe on prosociality are explained, in part, by feelings of a small self. These findings indicate that awe may help situate individuals within broader social contexts and enhance collective concern. (c) 2015 APA, all rights reserved).

    This paper is a report of a study conducted to identify and test the effectiveness of learning mechanisms applied by the nursing staff of hospital wards as a means of limiting medication administration errors. Since the influential report ;To Err Is Human', research has emphasized the role of team learning in reducing medication administration errors. Nevertheless, little is known about the mechanisms underlying team learning. Thirty-two hospital wards were randomly recruited. Data were collected during 2006 in Israel by a multi-method (observations, interviews and administrative data), multi-source (head nurses, bedside nurses) approach. Medication administration error was defined as any deviation from procedures, policies and/or best practices for medication administration, and was identified using semi-structured observations of nurses administering medication. Organizational learning was measured using semi-structured interviews with head nurses, and the previous year's reported medication administration errors were assessed using administrative data. The interview data revealed four learning mechanism patterns employed in an attempt to learn from medication administration errors: integrated, non-integrated, supervisory and patchy learning. Regression analysis results demonstrated that whereas the integrated pattern of learning mechanisms was associated with decreased errors, the non-integrated pattern was associated with increased errors. Supervisory and patchy learning mechanisms were not associated with errors. Superior learning mechanisms are those that represent the whole cycle of team learning, are enacted by nurses who administer medications to patients, and emphasize a system approach to data analysis instead of analysis of individual cases.

    Full Text Available Background: There is only little information about the effects of GABA receptors agonist and antagonist on morphine self-administration. Present study was designed to assess role of GABAB receptors in the regulation of morphine-reinforced self-administration. Methods: This study was performed in four groups of rats: (1 Saline group, which received saline in the self-administration session. (2 Morphine group, which received morphine in saline solution in the self-administration session. (3 Baclofen + Morphine group, which received both baclofen 20 min before self- administration test and morphine in the self-administration session. (4 Phaclofen + Morphine group, which received both phaclofen 20 min before self- administration test and morphine in the self-administration session. The number of lever pressing and self-infusion were recorded. Results: Morphine significantly increased the number of active lever pressing dose dependently in self-administration session in comparative with saline group. Administration of baclofen, 20 min before morphine self-administration produced significant decrease in the initiation of morphine self-administration during all session. Conversely, pre-treatment of phaclofen increased the number of active lever pressing and self-infusion in this test. Conclusion: Our results indicated a short-term treatment by baclofen, reduced morphine-maintenance response in a dose-dependent manner, suggesting that GABAB receptor agonists could be useful for reversing the neuroadaptations related to opiates.

Methods: We conducted a randomized clinical trial with colorectal cancer patients undergoing elective surgery, randomly assigned to receive symbiotics or placebo for five days prior to the surgical procedure and for 14 days after surgery. We studied 91 patients, 49 in the symbiotics group (Lactobacillus acidophilus 108 to 109 CFU, Lactobacillus rhamnosus 108 to 109 CFU, Lactobacillus casei 108 to 109 CFU, Bifi dobacterium 108 to 109 CFU and fructo-oligosaccharide (FOS 6g and 42 in the placebo group. Results: surgical site infection occurred in one (2% patient in the symbiotics group and in nine (21.4% patients in the control group (p=0.002. There were three cases of intraabdominal abscess and four cases of pneumonia in the control group, whereas we observed no infections in patients receiving symbiotics (p=0.001. Conclusion: the perioperative administration of symbiotics significantly reduced postoperative infection rates in patients with colorectal cancer. Additional studies are needed to confirm the role of symbiotics in the surgical treatment of colorectal cancer.

    1987-01-01

    The purpose of this work was to evaluate the effect of prolonged (immediate or delayed) administration of dietary additives to suckling rats on the absorption and retention of radioactive cerium in the body. The experiment was performed on 6-day-old suckling rats. According to dietary treatment the animals were divided into three groups. Each group was artificially fed over 8 h for 6 or 12 days on one of the diets: the first group of animals was fed milk, the second group was given ingredients of rat diet and the third received milk during the first 2 days of the experiment and the ingredients of rat diet afterwards. At the end of the artificial feeding period the pups returned to their mothers and suckled overnight. On the 1st day of the experiment the food was labelled with 141 Ce. Whole body radioactivity was determined in a double crystal scintillation counter every 48 h over a 12-day period. Half of the animals from each group were killed 6 days after 141 Ce administration and the other half after 12 days. At these intervals retention was determined in the gut, liver, kidneys and femur. The early and delayed administration of rat diet ingredients - fish meal, sunflower meal, alfalfa, cane molasses and premix - greatly reduced whole body retention. The early treatment was more efficacious than the delayed one. The reduction was mostly due to decreased gut retention but organ retentions were also lower. The results obtained indicate that by prolonged (immediate or delayed) administration of some dietary means the retention of radioactive cerium in sucklings can be significantly decreased. (orig.)

    Full Text Available Purpose. Postoperative urinary retention (POUR increases the duration of hospitalization and frequency and risk of urinary bladder catheterization. The objective of this study was to analyze the efficacy of intramuscularly administered drotaverine hydrochloride in the prevention of POUR in orthopedic patients. Methods. Two hundred and thirty patients 17–40 years of age undergoing lower limb orthopedic procedures under spinal anesthesia were enrolled in the study. The study group received 40 mg of drotaverine hydrochloride intramuscularly; the second group was the control. The main outcome measure was (1 the time to micturition and (2 the incidence of urinary bladder catheterization and time to catheterization. Results. Two hundred and one patients of 230 enrolled participants completed the study. Compared to the control group, the male patients in study group exhibited a shorter time to spontaneous micturition (441 versus 563 minutes, 95% CI of the difference of means between 39 and 205 minutes and a lower incidence of urinary bladder catheterization (4/75 versus 10/54 (RR 0.29, 95% CI: 0.1–0.87; P=0.0175. Conclusions. Intramuscular administration of drotaverine hydrochloride decreased the time to spontaneous micturition and decreased the incidence of urinary bladder catheterization in male patients who underwent orthopedic surgery under spinal anesthesia. This trial is registered with NCT02026427.

    Full Text Available An administrative contract is the will between a public authority either a person empowe¬red by it, and one or more natural or legal persons, whether private or public, pursuing the realization of a public interest and to which a special scheme of administrative law applies. The typology of administrative contracts is very varied, depending on the evolution of the society’s needs. Thus, they are currently included in the category of administrative contracts: concession contracts and public procurement contracts, contracts for the use of public goods, public management contracts, public-private partnership contracts, public lending contracts and constitutive documents of the associative structures of public authorities.

    α- N -acetylgalactosaminidase (nagalase) accumulates in the serum of cancer patients and its activity correlates with tumor burden, aggressiveness and clinical disease progression. The administration of GC protein-derived macrophage-activating factor (GcMAF) to cancer patients with elevated levels of nagalase has been associated with a decrease of serum nagalase activity and with significant clinical benefits. Here, we report the results of the administration of GcMAF to a heterogeneous cohort of patients with histologically diverse, advanced neoplasms, generally considered as "incurable" diseases. In most cases, GcMAF therapy was initiated at late stages of tumor progression. As this is an open-label, non-controlled, retrospective analysis, caution must be employed when establishing cause-effect relationships between the administration GcMAF and disease outcome. However, the response to GcMAF was generally robust and some trends emerged. All patients (n = 20) presented with elevated serum nagalase activity, well above normal values. All patients but one showed a significant decrease of serum nagalase activity upon weekly GcMAF injections. Decreased nagalase activity was associated with improved clinical conditions and no adverse side effects were reported. The observations reported here confirm and extend previous results and pave the way to further studies aimed at assessing the precise role and indications for GcMAF-based anticancer immunotherapy.

    To evaluate the efficacy of alpha-lipoic acid (ALA) administration on hormonal and metabolic parameters of obese PCOS patients. A group of 32 obese PCOS patients were selected after informed consent. 20 patients referred to have first grade relatives with diabetes type I or II. Hormonal and metabolic parameters as well as OGTT were evaluated before and after 12 weeks of ALA integrative administration (400 mg per os every day). ALA administration significantly decreased insulin, glucose, BMI and HOMA index. Hyperinsulinemia and insulin response to OGTT decreased both as maximal response (Δmax) and as AUC. PCOS with diabetes relatives showed the decrease also of triglyceride and GOT. Interestingly in all PCOS no changes occurred on all hormonal parameters involved in reproduction such as LH, FSH, and androstenedione. ALA integrative administration at a low dosage as 400 mg daily improved the metabolic impairment of all PCOS patients especially in those PCOS with familiar diabetes who have a higher grade of risk of NAFLD and predisposition to diabetes.

    1989-06-01

    Rats treated with recombinant human tumor necrosis factor-cachectin, 100 micrograms/kg ip twice daily for 5 consecutive days, had a 56% decrease in food intake, a 54% decrease in nitrogen balance, and a 23-g decrease in body weight gain vs. saline-treated controls. Concurrent neutral protamine hagedorn insulin administration of 2 U/100 g sc twice daily reversed all of these changes to control levels without causing any treatment deaths. The improvement seen with insulin was dose independent. Five days of cachectin treatment caused a severe interstitial pneumonitis, periportal inflammation in the liver, and an increase in wet organ weight in the heart, lungs, kidney, and spleen. Concurrent insulin treatment led to near total reversal of these histopathologic changes. Cachectin treatment did not significantly change blood glucose levels from control values of 130-140 mg/dl, but insulin plus cachectin caused a significant decrease in blood glucose from 1 through 12 h after injection. Administration of high-dose insulin can near totally reverse the nutritional and histopathologic toxicity of sublethal doses of cachectin in rats.

    1984-01-01

    The influence of a single dose of aspirin (5.4-7.4 mg/kg) on platelet uptake on 4-mm Dacron interposition grafts was studied in a baboon model using gamma camera scanning for 111-Indium labeled platelets. In vitro assessment of platelet function after aspirin administration revealed that in the baboon, as in the human, aspirin abolished arachidonic acid-induced platelet aggregation, prolonged the lag time between exposure to collagen and aggregation, and decreased plasma thromboxane B2 levels. Aspirin also prolonged the template bleeding time. Scans for 111-Indium labeled platelets revealed that pretreatment with a single dose of aspirin decreased platelet uptake on 4-mm Dacron carotid interposition grafts. This decrease in platelet uptake was associated with a significant improvement in 2-hour graft patency and with a trend toward improved 2-week patency

    To determine whether preoperative epidural administration of morphine and detomidine would decrease postoperative lameness after bilateral stifle arthroscopy in horses. Prospective clinical controlled study. Eight adult horses that had bilateral arthroscopic procedures, including drilling of cartilage and subchondral bone within the femoropatellar joints. Horses were randomly separated into 2 groups. Preoperatively, 4 horses were administered a combination of epidural morphine (0.2 mg/kg) and detomidine (30 microg/kg), and 4 horses were administered an equivalent volume of epidural saline (0.9% NaCl) solution. Postoperative pain was assessed using 6 video recordings made at hourly intervals of each horse at a walk. Assessments began 1 hour after recovery from anesthesia. The recordings were scrambled out of sequence and evaluated by 3 observers, unaware of treatment groups, who scored lameness from 0 to 4. Lameness scores of the 2 groups of horses were compared using a Wilcoxon's rank sum test. Heart and respiratory rates were also measured at each hourly interval and compared between groups using a repeated-measures ANOVA; statistical significance was set at P detomidine significantly decreased lameness and heart rates after bilateral stifle arthroscopy. The greatest decrease was detected at hours 1 and 2 after recovery from anesthesia. We conclude that horses undergoing a painful arthroscopic procedure of the stifle joint benefit from the administration of preoperative epidural morphine and detomidine. Preoperative epidural administration of detomidine and morphine may be useful in decreasing postoperative pain after stifle arthroscopy as well as pain associated with other painful disorders involving the stifle joint, such as septic arthritis and trauma.

    Allopregnanolone is a neurosteroid involved in depression, memory, social, and sexual behavior. We have previously demonstrated that treatment with a combination of ethinylestradiol (EE) and levonorgestrel (LNG), two compounds frequently used in hormonal contraception, decreased brain allopregnanolone concentrations. These changes may contribute to some of the emotional and sexual disorders observed in hormonal contraceptive users. We thus examined whether the reduction in allopregnanolone concentrations induced by long-term EE/LNG administration was associated with altered emotional, learning, social, and sexual behaviors. Rats were orally treated with a combination of EE (0.030 mg) and LNG (0.125 mg) once a day for 4 weeks and were subjected to behavioral tests 24 h after the last administration. EE/LNG treatment reduced immobility behavior in the forced swim test, without affecting sucrose preference and spatial learning and memory. In the resident-intruder test, EE/LNG-treated rats displayed a decrease in dominant behaviors associated with a reduction in social investigation. In the paced mating test, EE/LNG treated rats showed a reduction in proceptive behaviors, while the lordosis quotient was not affected. Progesterone, but not estradiol, administration to EE/LNG-treated rats increased sexual activity and cerebrocortical allopregnanolone concentrations. Prior administration of finasteride decreased allopregnanolone concentrations and abolished the increase in proceptivity induced by progesterone administration. The decrease in brain allopregnanolone concentrations induced by EE/LNG treatment is associated with a reduction in social behavior and sexual motivation in female rats. These results might be relevant to the side effects sometimes exhibited by women taking hormonal contraceptives.

    Full Text Available Public administration reform at all governmental levels constitutes an important component of the transformation process from a centralized system to democratic governance. This process involved important legislative and institutional changes in order to fulfill the principles of a market economy and the European Union standards based on transparency, predictability, accountability, adaptability and effectiveness. Therefore, in a continuing extension of the citizens’ needs, Romanian public administration reform, especially at local level, is concentrated on quality of public services based on citizens’ needs and increased performances in the context of a necessary decrease of budget expenditure, taking into consideration the actual financial constraint. In this context, it is useful to investigate the financial strategies of the local public administration based on the Romanian experiences that consisted in important public resources decline because of the financial crisis.

    N-acetylcysteine and bupropion are two promising candidate medications for treatment of substance use disorder. The effects of N-acetylcysteine or bupropion on methamphetamine self-administration of female rats are not well understood. To fill this gap, this study assessed the effects of N-acetylcysteine (0, 30, 60, or 120 mg/kg) and bupropion (0, 10, 30, and 60 mg/kg) on methamphetamine self-administration of female rats across the natural estrous cycle. Following a completed dose-response curve, responding for methamphetamine self-administration was extinguished and the effects of N-acetylcysteine or bupropion on methamphetamine-triggered reinstatement was evaluated in separate experiments. N-acetylcysteine did not decrease responding maintained by methamphetamine or methamphetamine-triggered reinstatement. Bupropion significantly decreased methamphetamine self-administration and methamphetamine-triggered reinstatement in female rats with highest dose (60 mg/kg) also significantly decreasing general chamber activity. In a companion experiment, testing the effect of bupropion on responding maintained by sucrose, we confirmed non-specificity of bupropion's effects as bupropion also decreased responding for sucrose. Considered together, our findings suggest that while N-acetylcysteine has considerable promise for treatment of cocaine dependence it may not generalize to other stimulants like methamphetamine. Furthermore, although bupropion has been shown to effectively decrease methamphetamine self-administration, and presently methamphetamine-triggered reinstatement, its locomotor and reward suppressing effects warrant further investigation including both sexes.

    The purpose of this work was to evaluate the effect of prolonged (immediate or delayed) administration of dietary additives to suckling rats on the absorption and retention of radioactive cerium in the body. The experiment was performed on 6-day-old suckling rats. According to dietary treatment the animals were divided into three groups. Each group was artificially fed over 8 h for 6 or 12 days on one of the diets: the first group of animals was fed milk, the second group was given ingredients of rat diet and the third received milk during the first 2 days of the experiment and the ingredients of rat diet afterwards. At the end of the artificial feeding period the pups returned to their mothers and suckled overnight. On the 1st day of the experiment the food was labelled with /sup 141/Ce. Whole body radioactivity was determined in a double crystal scintillation counter every 48 h over a 12-day period. Half of the animals from each group were killed 6 days after /sup 141/Ce administration and the other half after 12 days. At these intervals retention was determined in the gut, liver, kidneys and femur. The early and delayed administration of rat diet ingredients - fish meal, sunflower meal, alfalfa, cane molasses and premix - greatly reduced whole body retention. The early treatment was more efficacious than the delayed one. The reduction was mostly due to decreased gut retention but organ retentions were also lower. The results obtained indicate that by prolonged (immediate or delayed) administration of some dietary means the retention of radioactive cerium in sucklings can be significantly decreased.

    Delaying presentation of a drug can decrease its effectiveness as a reinforcer, but the effect of delaying punishment of drug self-administration is unknown. This study examined whether a histamine injection could punish cocaine self-administration in a drug-drug choice, whether delaying histamine would decrease its effectiveness, and whether the effects of delay could be described within a delay discounting framework. Monkeys were implanted with double-lumen catheters to allow separate injection of cocaine and histamine. In discrete trials, subjects first chose between cocaine (50 or 100 μg/kg/inj) alone and an injection of the same dose of cocaine followed immediately by an injection of histamine (0.37-50 μg/kg). Next, they chose between cocaine followed immediately by histamine and cocaine followed by an equal but delayed dose of histamine. When choosing between cocaine alone and cocaine followed immediately by histamine, preference increased with histamine dose from indifference to >80% choice of cocaine alone. When choosing between cocaine followed by immediate histamine and cocaine followed by delayed histamine, monkeys showed strong position preferences. When delayed histamine was associated with the nonpreferred position, preference for that option increased with delay from ≤30% to >85%. The corresponding decrease in choice of the preferred position was well described by a hyperboloid discounting function. Histamine can function as a punisher in the choice between injections of cocaine and delay can decrease its effectiveness as a punisher. The effects of delaying punishment of drug self-administration can be conceptualized within the delay discounting framework.

    Combining effective treatments with diverse mechanisms of action for smoking cessation may provide better therapy by targeting multiple points of control in the neural circuits underlying addiction. Previous research in a rat model has shown that dextromethorphan, which has α3β4 nicotinic and NMDA glutamatergic antagonist actions, significantly decreases nicotine self-administration. We have found in the rat model that the H1 histamine antagonist pyrilamine and the serotonin 5HT2C agonist lorcaserin also significantly reduce nicotine self-administration. The current studies were conducted to determine the interactive effects of dextromethorphan with pyrilamine and lorcaserin on nicotine self-administration in rats. Young adult female rats were fitted with jugular IV catheters and trained to self-administer a nicotine infusion dose of 0.03-mg/kg/infusion. In an initial dose-effect function study of dextromethorphan, we found a monotonic decrease in nicotine self-administration over a dose range of 1 to 30-mg/kg with the lowest effective dose of 3-mg/kg. Then, with two separate cohorts of rats, dextromethorphan (0, 3.3, and 10-mg/kg) interactions with pyrilamine (0, 4.43, and 13.3-mg/kg) were investigated as well as interactions with lorcaserin (0, 0.3125 and 0.625-mg/kg). In the pyrilamine-dextromethorphan interaction study, an acute dose of pyrilamine (13.3-mg/kg) as well as an acute dose of dextromethorphan caused a significant decrease in nicotine self-administration. There were mutually augmenting effects of these two drugs. The combination of dextromethorphan (10-mg/kg) and pyrilamine (13.3-mg/kg) significantly lowered nicotine self-administration relative to either 10-mg/kg of dextromethorphan alone (pdextromethorphan study, an acute dose of lorcaserin (0.312-mg/kg) as well as an acute dose of dextromethorphan (10-mg/kg) caused a significant decrease in nicotine self-administration replicating previous findings. Augmenting interactions were observed with

    Ten cases of hepatocellular carcinoma and three cases of metastatic liver tumor were evaluated using breath-hold multishot echo planar imaging (EPI) before and after administration of super-paramagnetic iron oxide (SPIO), and the results were compared to those with breath-hold fast multi-planar SPGR (T 1 WI) and fat-suppressed respiratory-triggered FSE (T 2 WI). Qualitative imaging evaluation of lesion detectability showed that T 2 WI was much more useful than T 1 WI as previously reported, and more useful than EPI. Quantitative evaluation showed that the signal to noise (S/N) ratios of the liver parenchyma decreased after administration of SPIO and the changes were significant on all pulse sequences. The change ratio of the S/N ratio of the liver parenchyma after administration of SPIO on EPI was significantly higher than on T 1 WI and T 2 WI. The tumor-liver contrast to noise (C/N) ratios increased after administration of SPIO and the changes were significant on T 1 WI and T 2 WI, but not on EPI. These results suggested that the tumor S/N ratio decreased after administration of SPIO on EPI. The tumor diameters on EPI were significantly reduced after administration of SPIO. Magnetization and flow artifacts on EPI were detected in all cases and caused distortion: the signal decreased in the liver parenchyma. We concluded that EPI after administration of SPIO is not currently useful compared to other pulse sequences and cannot yet replace T 2 WI. (author)

    We describe how brain regions with a flow (and metabolism) decrease can be visualized after an injection of short-acting barbiturate in one of the internal carotid arteries during a Wada test. An intravenous administration of 99mTc-HMPAO was used to mark the relative flow distribution. The 99mTc-HMPAO distribution in the brain was recorded three-dimensionally about 1 h later, by means of a single photon emission computer tomograph. We show that the timing of the intravenous 99mTc-HMPAO administration during the Wada test is important for the visualization of the low-flow regions. The administration of the tracer substance should be delayed at least 30 s after the first signs of the barbiturate effect. The rCBF decrease in the barbiturate-injected cerebral hemisphere was associated with a simultaneous decrease in the contralateral, pharmacologically not directly affected, cerebellar hemisphere (crossed cerebellar diaschisis).

    It has been reported that chronic sennoside use is associated with the development of melanosis coli, colonic adenoma, and/or carcinomas. In this study, we investigated the immunological changes in the colon and skin after the administration of senna. In this study, we investigated the colon and epidermis of C57/BL6j mice after a single administration of 10 mg/kg of senna [Cassia angustifolia (Caesalpiniaceae); 3, 6, 12, and 24 h after administration] and after repeated once per week administrations (on days 3, 5, 7, 14, and 21 of administration). The LD50 and ED50 of senna used in this experiment were 165 mg/kg and 13 g/kg, respectively. We demonstrated that the DOPA-positive cells in the colon increased at 12 h after single administration and were further increased from at 5-28 d after repeated administration. We also studied the physiological changes of the small intestine using the charcoal meal test. We found that there was a tendency for peristalsis to be inhibited after repeated senna administration. In the epidermis, we investigated the number of Langerhans cells, because they are important immune cells of the skin. The number of these cells decreased, especially after repeated administration. The present findings suggested that it is necessary to pay attention to not only the intestine but also the skin, during long-term senna treatment.

    To evaluate the role of health plan benefit design and price on consumers' decisions to purchase health insurance in the nongroup market and their choice of plan. Administrative data from the three largest nongroup insurers in California and survey data about those insured in the nongroup market and the uninsured in California. We fit a nested logit model to examine the effects of plan characteristics on consumer choice while accounting for substitutability among certain groups of products. Product choice is quite sensitive to price. A 10 percent decrease in the price of a product would increase its market share by about 20 percent. However, a 10 percent decrease in prices of all products would only increase overall market participation by about 4 percent. Changes in the generosity of coverage will also affect product choice, but have only small effects on overall participation. A 20 percent decrease in the deductible or maximum out-of-pocket payment of all plans would increase participation by about 0.3-0.5 percent. Perceived information search costs and other nonprice barriers have substantial effects on purchase of nongroup coverage. Modest subsidies will have small effects on purchase in the nongroup market. New product designs with higher deductibles are likely to be more attractive to healthy purchasers, but the new benefit designs are likely to have only small effects on market participation. In contrast, consumer education efforts have a role to play in helping to expand coverage.

    Full Text Available Garlic (Allium sativum, Liliaceae has been safely used for more than 5000 years, and research on garlic extract is rapidly increasing because of its multiple biological functions. The in vivo effects of oral administration of garlic mixture (GM, water-soluble extract on infectious bursal disease virus (IBDV-infected specific pathogen free male white leghorn chicken were examined through histopathological, immunohistochemical, and Western blot analyses, and enzyme-linked immunosorbent assay. The results confirmed the protective effects of oral administration of 5 mg·kg-1 BW GM (Group GM1 on bursal lesions after IBDV infection. In particular, protein expression of IBDV in the bursa decreased in Group GM1, indicating that GM administration decreased IBDV replication in the bursa. Furthermore, immunoglobulin M- and A-bearing B lymphocytes significantly increased 7 days post infection in bursae in Group GM1 (P<0.01, suggesting that the oral administration of 5 mg·kg-1 GM offers moderate protection against B cell destruction after IBDV infection. During infection, the concentration of bursal interferon gamma (IFN-g increased and peaked in Group GM1 earlier than in Group T (IBDV-exposed, demonstrating that GM administration prompted the production of IFN-g to protect against IBDV infection.

  4. Ursodeoxycholic Acid Suppresses Lipogenesis in Mouse Liver: Possible Role of the Decrease in β-Muricholic Acid, a Farnesoid X Receptor Antagonist.

    The farnesoid X receptor (FXR) is a major nuclear receptor of bile acids; its activation suppresses sterol regulatory element-binding protein 1c (SREBP1c)-mediated lipogenesis and decreases the lipid contents in the liver. There are many reports showing that the administration of ursodeoxycholic acid (UDCA) suppresses lipogenesis and reduces the lipid contents in the liver of experimental animals. Since UDCA is not recognized as an FXR agonist, these effects of UDCA cannot be readily explained by its direct activation of FXR. We observed that the dietary administration of UDCA in mice decreased the expression levels of SREBP1c and its target lipogenic genes. Alpha- and β-muricholic acids (MCA) and cholic acid (CA) were the major bile acids in the mouse liver but their contents decreased upon UDCA administration. The hepatic contents of chenodeoxycholic acid and deoxycholic acid (DCA) were relatively low but were not changed by UDCA. UDCA did not show FXR agonistic or antagonistic potency in in vitro FXR transactivation assay. Taking these together, we deduced that the above-mentioned change in hepatic bile acid composition induced upon UDCA administration might cause the relative increase in the FXR activity in the liver, mainly by the reduction in the content of β-MCA, a farnesoid X receptor antagonist, which suggests a mechanism by which UDCA suppresses lipogenesis and decreases the lipid contents in the mouse liver.

    Full Text Available Modafinil (2-((diphenylmethylsulfinylacetamide, a selective dopamine and norepinephrine transporter inhibitor, is most commonly prescribed for narcolepsy but has gained recent interest for treating a variety of disorders. Zebrafish (Danio rerio are becoming a model of choice for pharmacological and behavioural research. To investigate the behavioural effects of modafinil on anxiety, we administered doses of 0, 2, 20, and 200 mg/L for 30 minutes then tested zebrafish in the novel approach test. In this test, the fish was placed into a circular arena with a novel object in the center and motion-tracking software was used to quantify the time the fish spent in the outer area of the arena (thigmotaxis zone, middle third of the arena (transition zone and center of the arena, as well as total distance traveled, immobility and meandering. Modafinil caused a decrease in time spent in the thigmotaxis zone and increased time spent in the transition zone across all doses. Modafinil did not significantly alter the time spent in the center zone (near the novel object, the distance moved, meandering, or the duration of time spent immobile. We also validated this test as a measure of anxiety with the administration of ethanol (1% which decreased time spent in the thigmotaxis zone and increased time spent in the transition zone. These results suggest that modafinil decreases anxiety-like behaviour in zebrafish.

    Cabergoline is an ergotamine derivative that increases the expression of glial cell line-derived neurotrophic factor (GDNF) in vitro. We recently showed that GDNF in the ventral tegmental area (VTA) reduces the motivation to consume alcohol. We therefore set out to determine whether cabergoline administration decreases alcohol-drinking and -seeking behaviors via GDNF. Reverse transcription polymerase chain reaction (RT-PCR) and Enzyme-Linked ImmunoSorbent Assay (ELISA) were used to measure GDNF levels. Western blot analysis was used for phosphorylation experiments. Operant self-administration in rats and a two-bottle choice procedure in mice were used to assess alcohol-drinking behaviors. Instrumental performance tested during extinction was used to measure alcohol-seeking behavior. The [35S]GTPgammaS binding assay was used to assess the expression and function of the dopamine D2 receptor (D2R). We found that treatment of the dopaminergic-like cell line SH-SY5Y with cabergoline and systemic administration of cabergoline in rats resulted in an increase in GDNF level and in the activation of the GDNF pathway. Cabergoline treatment decreased alcohol-drinking and -seeking behaviors including relapse, and its action to reduce alcohol consumption was localized to the VTA. Finally, the increase in GDNF expression and the decrease in alcohol consumption by cabergoline were abolished in GDNF heterozygous knockout mice. Together, these findings suggest that cabergoline-mediated upregulation of the GDNF pathway attenuates alcohol-drinking behaviors and relapse. Alcohol abuse and addiction are devastating and costly problems worldwide. This study puts forward the possibility that cabergoline might be an effective treatment for these disorders.

    The effects of repeated ip administration of gallic acid, 4,5-dihydroxy-1,3-benzenedisulfonic acid (Tiron), diethylenetriaminepentaacetic acid (DTPA), and 5-aminosalicylic acid (5-AS) on the distribution and excretion of uranium were assessed in male Swiss mice. Only Tiron significantly increased the amount of uranium excreted into urine and feces. A significant decrease in the concentration of uranium in liver, spleen and bone was observed after administration of Tiron, whereas injection of gallic acid or DTPA resulted in a significant decrease in the concentration of the metal in the liver. The results show that Tiron was consistently the most effective chelator of those tested in the treatment of uranium poisoning after repeated daily administration of the metal

    The purpose of this study is to investigate the effects of administration order when a sedative drug (midazolam) and an opioid analgesic drug (fentanyl) is applied for moderate intravenous (IV) sedation in dentistry. A retrospective chart review was conducted in one dental clinic during its transition from a midazolam-first to a fentanyl-first protocol for dental procedures requiring moderate IV sedation. Physiological parameters, drug administration times, patient recovery times, drug dosages, and patient recall and satisfaction were investigated for differences. A total of 76 charts (40 midazolam-first and 36 fentanyl-first administrations), were used in the analysis. Administering midazolam first resulted in an average 4.38 min (52%) decrease in administration times (P 0.05). Oxygen saturation levels did not drop below 90% for either group; however, 5 cases in the fentanyl-first group fell to between 90% and 92%, compared with 0 cases in the midazolam-first group. The administration order of fentanyl and midazolam may have different effects on patients and the sedation procedure. Findings from this study should be used to facilitate discussion among dental practitioners and to guide additional research investigating this topic.

    Increasing evidence suggests that not only genetics, but also environmental factors like gut microbiota dysbiosis play an important role in the pathogenesis of celiac disease (CD). The aim of our study was to investigate the effect of two probiotic strains Bifidobacterium breve BR03 and B. breve B632 on serum production of anti-inflammatory cytokine interleukin 10 (IL-10) and pro-inflammatory cytokine tumor necrosis factor alpha (TNF-α) in children with CD. The study was a double-blinded, placebo-controlled trial that included 49 children with CD on gluten-free diet (GFD) randomized into two groups and 18 healthy children in the control group. The first group (24 children with CD) daily received B. breve BR03 and B632 (2 × 10(9) colony-forming units) and the second group (25 children with CD) received placebo for 3 months. TNF-α levels were significantly decreased in the first group after receiving B. breve for 3 months. On follow-up, 3 months after receiving probiotics, TNF-α levels increased again. Children with CD who were on GFD for less than 1 year showed similar baseline TNF-α levels as children who were on GFD for more than 1 year. IL-10 levels were in all groups of patients below detection level. Probiotic intervention with B. breve strains has shown a positive effect on decreasing the production of pro-inflammatory cytokine TNF-α in children with CD on GFD.

    The Alzheimer's Disease Assessment Scale - Cognitive (ADAS-Cog) is the most commonly used primary outcome instrument in clinical trials for treatments of dementia. Variations in forms, administration procedures and scoring rules, along with rater turnover and intra-rater drift may decrease the reliability of the instrument. A survey of possible variations in the ADAS-Cog was administered to 26 volunteer raters at a clinical trials meeting. Results indicate notable protocol variations in the forms used, administration procedures, and scoring rules. Since change over time is used to determine treatment effect in clinical trials, standardizing the instrument's ambiguities and addressing common problems will greatly increase the instrument's reliability and thereby enhance its sensitivity to treatment effects.

  14. MOTIVATION OF ADMINISTRATIVE ACTS – GUARANTEE OF GOOD ADMINISTRATION

    Directory of Open Access Journals (Sweden)

    2018-05-01

    Full Text Available The present article deals with the aspects of motivating administrative acts, both doctrinaire and practical, of jurisprudence. The duty of the administration to motivate its decisions is submitted in the Charter of Fundamental Rights of the European Union, art. 41. In the current European legal order, the rationale for administrative acts is considered and refers to one of the most important conditions of validity of the administrative act. The Romanian Constitution ensures and emphasizes the motivation, as it is imposed by the Charter. The realization of this fundamental right to motivate administrative acts is possible by calling upon a set of values from the administration, such as transparency, professionalism and the imposition of high quality standards. Motivation is achieved where we have a good administration, and whether citizens are, among other things, respected fundamental rights and freedoms, access to information is guaranteed and motivated their decisions. Although administrative normative acts are motivated by the administration, examples that show that individual ones are unmotivated or incompletely motivated are enough, which made the various employers legally answer for the non-motivation of their decisions to terminate work relationships with several of the employees. The motivation of administrative acts is necessary, mandatory and must be done with rigor. It is highlighted that inadequate, incomplete or vicious reasoning may result in suspension or even annulment of the administrative act by the court.

    Full Text Available The article presents an analysis of outsourcing in the Brazilian Public Administration and the way it currently operates, initiating a process of reform, aiming to reduce the size of the administrative apparatus. Several doctrinal and jurisprudential concepts have been demonstrated in order to demonstrate in a concise way the applicability of outsourcing as a mechanism to reduce costs of the public machine, increase its efficiency and decrease its size. Some advantages of the use of outsourcing by the public administration by several jurists are presented, including the gains in competitiveness and ease of supervision by the citizens. The extension of the responsibility of the public administration by the outsourced company and the way in which it operates, in the light of the legislation, jurisprudence and the best doctrine, suggest efficient alternatives in the exercise of the administration, increasing its credibility and efficiency in the attainment of governmental objectives. The methodology used was through deductive. The achieved results demonstrate that the process of outsourcing after quality and a new dynamics in the public service.

    To examine the effect of implementing electronic order management on the timely administration of antibiotics to critical-care patients. We used a prospective pre-post design, collecting data on first-dose IV antibiotic orders before and after the implementation of an integrated electronic medication-management system, which included computerized provider order entry (CPOE), pharmacy order processing and an electronic medication administration record (eMAR). The research was performed in a 24-bed adult medical/surgical ICU in a large, rural, tertiary medical center. Data on the time of ordering, pharmacy processing and administration were prospectively collected and time intervals for each stage and the overall process were calculated. The overall turnaround time from ordering to administration significantly decreased from a median of 100 min before order management implementation to a median of 64 min after implementation. The first part of the medication use process, i.e., from order entry to pharmacy processing, improved significantly whereas no change was observed in the phase from pharmacy processing to medication administration. The implementation of an electronic order-management system improved the timeliness of antibiotic administration to critical-care patients. Additional system changes are required to further decrease the turnaround time. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Subcutaneous (SC) administration of tramadol was compared with intravenous (IV) administration to evaluate analgesia following canine ovariohysterectomy (OHE). Healthy female dogs (n = 12) between 1 and 3 years of age (1.95 ± 0.65 years), weighing between 10.5 and 17.1 kg (13.12 ± 1.95 kg), were used. Pain was assessed at baseline before surgery and then hourly for 8 hr after surgery. Tramadol was administered both SC and IV at a dose of 3 mg/kg and provided significant postoperative analgesia, as indicated by analgesiometry, β-endorphin levels, and interleukin 6 (IL-6) levels. The respiratory rates and rectal temperatures remained normal and were not significantly different between or within the groups. A significant increase in heart rate was observed at 4 hr for dogs in both groups relative to the baseline, but there was no significant difference in heart rates between the groups at any time point. A significant decrease in mechanical pain threshold was observed within each group after surgery, but both groups responded similarly, suggesting that SC administration of tramadol is as effective as IV administration. Increased serum levels of both IL-6 and β-endorphin 3 hr postoperatively further indicate that both routes of administration achieve similar pain control. Thus, the relative analgesic efficacy of SC tramadol is comparable to that of IV administration and can be used to achieve similar effects for postsurgical pain management in dogs undergoing OHE.

    The objective of the present study was to investigate hospital administrator's expectations about the administrative role played by nurses, utilizing functions proposed by the Neoclassical Theory of Administration: planning, organization, direction, and control as theoretical references. An instrument established in TREVIZAN (1989) was applied to 11 hospital administrators. The results showed they expect the four functions to be done by nurses. Therefore, the interaction between nurses and hospital administrators is critical to improve the patient's assistance.

    The effect of Centchroman, 3,4-trans-2,2-dimethyl-3-phenyl-4-para-(beta -pyrrolidinoethocy)-phenyl-7-methorychroman, administration was investigated in normospermic and oligospermic subjects. 3 normal volunteers, aged 32-40 years, were treated with increasing doses (30, 60, and 120 mg/day, each dose for 2 weeks). The sperm count was decreased in 1 volunteer but the percentages of nonmotile and abnormal spermatozoa were increased in all 3. There was no change in plasma testosterone and urinary 17-ketosteroid (17-KS) levels but the 17-ketogenic steroids (17-KGSs) were decreased in all of them. 3 out of 5 oligospermic subjects, aged 24-35 years, who received 30 mg/day for 6 weeks revealed increased sperm counts. Plasma testosterone levels were decreased in 4, urinary 17-KGSs were decreased in 2, and 17-KSs were decreased in 1 subject. Acid phosphatase, fructose, sialic acid and glycerylphosphoryl choline levels in semen, and serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, alkaline phosphatase, and urea in blood were not markedly altered in either group.

    Hibiscus taiwanensis (Malvaceae) is widely used as an alternative herb to treat disorders in Taiwan. In the present study, it is used to screen the effect on diabetic hyperglycemia in streptozotocin-induced diabetic rats (STZ-diabetic rats). The extract of Hibiscus taiwanensis showed a significant plasma glucose-lowering action in STZ-diabetic rats. Stems of Hibiscus taiwanensis are more effective than other parts to decrease the plasma glucose in a dose-dependent manner. Oral administration of Hibiscus taiwanensis three times daily for 3 days into STZ-diabetic rats increased the sensitivity to exogenous insulin showing an increase in insulin sensitivity. Moreover, similar repeated administration of Hibiscus taiwanensis for 3 days in STZ-diabetic rats produced a marked reduction of phosphoenolpyruvate carboxykinase (PEPCK) expression in liver and an increased expression of glucose transporter subtype 4 (GLUT 4) in skeletal muscle. Taken together, our results suggest that Hibiscus taiwanensis has the ability to lower plasma glucose through an increase in glucose utilization via elevation of skeletal GLUT 4 and decrease of hepatic PEPCK in STZ-diabetic rats.

    Hypertension is more common in eldery female that triggered by diet and lifestyle changes. Bananas were not only useful for the food, but also for hypertension therapy and preserving life. Administration of bananas decreased blood pressure in hypertensive patients. This study aims to identify of factors that influenced by the administration of banana (Musa paradisiaca) on elderly female hypertensive patient. Twenty of eldery female patient were divided into 2 respondents group: control (11 patients) and treatment (9 patients). The treatment groups received banana twice a day during 2 weeks, but the control group didn’t. Here, we showed the administration of banana significantly decreased blood pressure on elderly female hypertensive patient (p = 0.00) in both systole and diastole. There was a significant decrease in sodium levels (p = 0.037) in the blood, but potassium levels remained the same. Erythrocyte sedimentation level (p = 0.136) and trombocyte count (p = 0.176) in treatment group, were not affected by banana administration. Taken together, banana administration on elderly female hypertensive patient decreased the blood pressure significantly, greatly affected by the natrium dischargement from the blood. Thus, our findings contribute to preliminary comprehension of banana effect on hypertension reduction.

    To examine President Obama's fiscal commitment to the Ryan White Program (formerly Ryan White Comprehensive AIDS Resource Emergency Act), which provides funding for economically disadvantaged people and families affected by HIV. We analyzed budgetary request and congressional appropriation data from 2009 to 2016. The data are available from the Health Resources and Services Administration and the Henry J. Kaiser Family Foundation. Increased coverage for people living with HIV/AIDS provided by the Affordable Care Act most likely led the Obama administration to request small increases and at times decreases in funding for the Ryan White Program. Congress passed either small increases or decreases in appropriations for the Ryan White Program. Decreases or small increases in the Ryan White Program funding risk progress made in treating HIV among economically disadvantaged patients.

  8. The Contingency of Cocaine Administration Accounts for Structural and Functional Medial Prefrontal Deficits and Increased Adrenocortical Activation

    The prelimbic region (PL) of the medial prefrontal cortex (mPFC) is implicated in the relapse of drug-seeking behavior. Optimal mPFC functioning relies on synaptic connections involving dendritic spines in pyramidal neurons, whereas prefrontal dysfunction resulting from elevated glucocorticoids, stress, aging, and mental illness are each linked to decreased apical dendritic branching and spine density in pyramidal neurons in these cortical fields. The fact that cocaine use induces activation of the stress-responsive hypothalamo-pituitary-adrenal axis raises the possibility that cocaine-related impairments in mPFC functioning may be manifested by similar changes in neuronal architecture in mPFC. Nevertheless, previous studies have generally identified increases, rather than decreases, in structural plasticity in mPFC after cocaine self-administration. Here, we use 3D imaging and analysis of dendritic spine morphometry to show that chronic cocaine self-administration leads to mild decreases of apical dendritic branching, prominent dendritic spine attrition in PL pyramidal neurons, and working memory deficits. Importantly, these impairments were largely accounted for in groups of rats that self-administered cocaine compared with yoked-cocaine- and saline-matched counterparts. Follow-up experiments failed to demonstrate any effects of either experimenter-administered cocaine or food self-administration on structural alterations in PL neurons. Finally, we verified that the cocaine self-administration group was distinguished by more protracted increases in adrenocortical activity compared with yoked-cocaine- and saline-matched controls. These studies suggest a mechanism whereby increased adrenocortical activity resulting from chronic cocaine self-administration may contribute to regressive prefrontal structural and functional plasticity. SIGNIFICANCE STATEMENT Stress, aging, and mental illness are each linked to decreased prefrontal plasticity. Here, we show that chronic

    Capsaicin has been reported to have unique thermoregulatory actions. However, changes in core temperature after the administration of capsaicin are a controversial point. Therefore, we investigated the effects of environmental thermal conditions on changes in body temperature caused by capsaicin in mice. We showed that intragastric administration of 10 and 15 mg/kg capsaicin increased tail temperature and decreased colonic temperatures in the core temperature (CT)-constant and CT-decreasing conditions. In the CT-increasing condition, 15 mg/kg capsaicin increased tail temperature and decreased colonic temperature. However, 10 mg/kg capsaicin increased colonic temperature. Furthermore, the amount of increase in tail temperature was greater in the CT-decreasing condition and lower in the CT-increasing condition, compared with that of the CT-constant condition. These findings suggest that the changes in core temperature were affected by the environmental thermal conditions and that preliminary thermoregulation state might be more important than the constancy of temperature to evaluate the effects of heat diffusion and thermogensis.

    Fas stimulation recruits neutrophils and activates macrophages that secrete tumor necrosis factor-α (TNF-α), which aggravates Fas-mediated liver injury. To determine whether nonsteroidal anti-inflammatory drugs modify these processes, we challenged 24-hour-fasted mice with the agonistic Jo2 anti-Fas antibody (4 μg/mouse), and treated the animals 1 h later with saline or ibuprofen (250 mg/kg), a dual cyclooxygenase (COX)-1 and COX-2 inhibitor. Ibuprofen attenuated the Jo2-mediated recruitment/activation of myeloperoxidase-secreting neutrophils/macrophages in the liver, and attenuated the surge in serum TNF-α. Ibuprofen also minimized hepatic glutathione depletion, Bid truncation, caspase activation, outer mitochondrial membrane rupture, hepatocyte apoptosis and the increase in serum alanine aminotransferase (ALT) activity 5 h after Jo2 administration, to finally decrease mouse mortality at later times. The concomitant administration of pentoxifylline (decreasing TNF-α secretion) and infliximab (trapping TNF-α) likewise attenuated the Jo2-mediated increase in TNF-α, the decrease in hepatic glutathione, and the increase in serum ALT activity 5 h after Jo2 administration. The concomitant administration of the COX-1 inhibitor, SC-560 (10 mg/kg) and the COX-2 inhibitor, celecoxib (40 mg/kg) 1 h after Jo2 administration, also decreased liver injury 5 h after Jo2 administration. In contrast, SC-560 (10 mg/kg) or celecoxib (40 or 160 mg/kg) given alone had no significant protective effects. In conclusion, secondary TNF-α secretion plays an important role in Jo2-mediated glutathione depletion and liver injury. The combined inhibition of COX-1 and COX-2 by ibuprofen attenuates TNF-α secretion, glutathione depletion, mitochondrial alterations, hepatic apoptosis and mortality in Jo2-treated fasted mice

    This current investigation was conducted on male albino rats to elucidate the effects of curcumin alone or in the presence of phenobarbital at low dose to decrease the progress of hepato-gastrointestinal carcinogenesis induced by N-diethylnitrosoamine (DEN) in rats. As a result of cancer induction, the levels of serum tumour markers [carcino-embryonic antigen (CEA), alpha-fetoprotein (AFP) and cancer antigen (CA19.9)] were significantly elevated. On the other hand, glutathione (GSH) and glutathione peroxidase (GPx) were decreased significantly in blood, liver, stomach and intestine whereas the levels of malondialdehyde (MAD) in liver, stomach and intestine were significantly elevated in the cancer group of rats in comparison to their corresponding control group. The administration of curcumin alone or together with phenobarbital ameliorated all these alterations depending on the time of administration. The data of this study suggested that low dose of phenobarbital in the presence of curcumin may inhibit the development of hepato-gastrointestinal carcinogenesis initiated with DEN.

    Full Text Available Insufficient detoxification and/or overproduction of reactive oxygen species (ROS induce cellular and tissue damage, and generated reactive oxygen metabolites become exacerbating factors of dermatitis. Keishibukuryogan-ka-yokuinin (KBGY is a traditional Japanese medicine prescribed to treat dermatitis such as acne vulgaris. Our aim was to verify the antioxidant properties of KBGY, and identify its active constituents by blood pharmacokinetic techniques. Chemical constituents were quantified in extracts of KBGY, crude components, and the plasma of rats treated with a single oral administration of KBGY. Twenty-three KBGY compounds were detected in plasma, including gallic acid, prunasin, paeoniflorin, and azelaic acid, which have been reported to be effective for inflammation. KBGY decreased level of the diacron-reactive oxygen metabolites (d-ROMs in plasma. ROS-scavenging and lipid hydroperoxide (LPO generation assays revealed that gallic acid, 3-O-methylgallic acid, (+-catechin, and lariciresinol possess strong antioxidant activities. Gallic acid was active at a similar concentration to the maximum plasma concentration, therefore, our findings indicate that gallic acid is an important active constituent contributing to the antioxidant effects of KBGY. KBGY and its active constituents may improve redox imbalances induced by oxidative stress as an optional treatment for skin diseases.

    Full Text Available Along with the expenditures for social protection, social security funds finance administrative direction, which should correspond to the amount of functions performed by a particular fund. The purpose of the paper is to determine ways to reduce administrative expenditures of state social security funds in the conditions of reforming Ukrainian economy. For this purpose, the authors investigate distribution of the expenditures between social security funds, analyse dynamics and structure of assignments for fund administration, and suggest possible ways to rationalize maintenance cost for these institutions. Methodology. Administrative expenditures are an integral part of the cost of social security funds and include particular items of expenses in the budget of these institutions. Applying a systematic approach to calculating the administrative costs of social security funds of Ukraine the authors have taken into account the expenditures related to funding management, support for information systems, and organization of work with insured people. Results of the survey showed that in 2007–2016 Pension Fund of Ukraine incurred the largest part of social expenditures (more than 90% compared with other social insurance funds (less than 10%. At the same time, the administrative expenses were divided approximately into two halves between Pension Fund and other social security funds. In 2015, the government launched a reform of social insurance funds that aimed to reduce funds to three institutions but a decrease in the total amount of administrative expenditures has not been achieved yet. In addition, Pension Fund of Ukraine was least burdened with administrative expenses, while other social security funds with a relatively small share of social expenditures were burdened with administrative expenditures much more. Practical implications. Research showed that nowadays the existence of several social security funds in Ukraine is economically

  16. Explaining the Behavioral Intention towards BI Implementation in Public Administrations - A Principal-Agent Theory Approach

    Science.gov (United States)

    Becker, Jörg; Bergener, Philipp; Lis, Łukasz; Niehaves, Björn

    Business Intelligence (BI) is an established instrument to support public administrations in their management tasks by increasing their information level. BI is of special interest in the context of introducing accrual accounting in public administrations as this affects the information level of different stakeholders, leading to a possible decrease for municipal councils. The principal-agent theory can help to explain different behavioral intentions of the stakeholders concerning the introduction of BI. We employ a single qualitative case study to analyze these behavioral intentions. It shows that the introduction of accrual accounting did decrease the information level of the municipal council making the principal-agent problems possible. Furthermore, it shows that BI might be a solution for this problem. Therefore, council members show the behavioral intention to support the BI implementation while administration staff members rather resist it. Based on these finding, we discuss implications for practice and future research.

  17. Fra egoisme til sjenerøsitet – kan toppidretten reformeres?

    Full Text Available Artikkelen tar utgangspunkt i den norske idrettsmodellen der topp og bredde hører sammen, og der toppidrettsutøvere uvegerlig blir rollemodeller for barn og unge. Den moderne toppidretten er i økende grad preget av egoistiske holdninger der det dreier seg hele tiden om å skaffe seg fordeler. I denne artikkelen tar jeg opp egoisme, rettferdighet og sjenerøsitet som tre grunnleggende holdninger i idrettskonkurranser og drøfter hvorvidt man med inspirasjon fra sjenerøsitetsidealer og praktiske eksempler kan tenke seg en toppidrett som i større grad bygger på sjenerøsitet. Artikkelen starter med en kort presentasjon av den norske idrettsmodellen og jeg skisserer deretter tre kriterier som alle idrettskonkurranser må oppfylle: 1 spille for å vinne, 2 klare regler som følges, og 3 respekt for konkurrenter. Deretter presenterer jeg egoisme, fairness og sjenerøsitet som tre mulige grunnholdninger, og de implikasjonene de har i en idrettslig sammenheng. Etter en gjennomgang av den grunnleggende egoismen i dagens toppidrett, som infiserer ikke bare utøveren, men også hele systemet rundt utøveren, diskuteres muligheten for å utvikle holdninger basert på sjenerøsitet. Det nevnes tre kilder til inspirasjon; engelsk overklassesport, Nietzsches tanker om den overlegne mester, og Arne Næss' sportspraksis og hans saklighetslære for gode diskusjoner. Deretter presenteres empiriske eksempler på sjenerøsitet og hva en spillteoretisk analyse av ulike holdninger gir som resultat. Jeg konkluderer med at en endring i retning av sjenerøsitet vil gi en rikere toppidrett og et bedre grunnlag for en helhetlig idrettsmodell.Nøkkelord: etikk, idrett, egoisme, rettferdighet, sjenerøsitetEnglish summary: From egoism to generosity – can elite sport be reformed?The Norwegian sport model can be visualized as a pyramid with mass sport at the base and elite sport at the top.

    Aerobic exercise can serve as an alternative, non-drug reinforcer in laboratory animals and has been recommended as a potential intervention for substance abusing populations. Unfortunately, relatively little empirical data have been collected that specifically address the possible protective effects of voluntary, long-term exercise on measures of drug self-administration. The purpose of the present study was to examine the effects of chronic exercise on sensitivity to the positive-reinforcing effects of cocaine in the drug self-administration procedure. Female rats were obtained at weaning and immediately divided into two groups. Sedentary rats were housed individually in standard laboratory cages that permitted no exercise beyond normal cage ambulation; exercising rats were housed individually in modified cages equipped with a running wheel. After 6 weeks under these conditions, rats were surgically implanted with venous catheters and trained to self-administer cocaine on a fixed-ratio schedule of reinforcement. Once self-administration was acquired, cocaine was made available on a progressive ratio schedule and breakpoints were obtained for various doses of cocaine. Sedentary and exercising rats did not differ in the time to acquire cocaine self-administration or responding on the fixed-ratio schedule of reinforcement. However, on the progressive ratio schedule, breakpoints were significantly lower in exercising rats than sedentary rats when responding was maintained by both low (0.3mg/kg/infusion) and high (1.0mg/kg/infusion) doses of cocaine. In exercising rats, greater exercise output prior to catheter implantation was associated with lower breakpoints at the high dose of cocaine. These data indicate that chronic exercise decreases the positive-reinforcing effects of cocaine and support the possibility that exercise may be an effective intervention in drug abuse prevention and treatment programs.

    Here we report a case of a 10-year-old female with unclassified epileptic encephalopathy who showed forced normalization after administration of levetiracetam (LEV). She initially presented with intractable tonic and myoclonic seizures that were observed about 10 times a day along with frequent multifocal sharp and slow wave complexes on electroencephalography (EEG). We were forced to decrease the topiramate dose because of the appearance of nystagmus, and her myoclonic seizures became worse. We added LEV (250 mg/day) and her tonic and myoclonic seizures disappeared one day after initiation of LEV administration. However, she showed hyporesponsiveness and akinesia. The disappearance of paroxysmal discharges on EEG confirmed the diagnosis of forced normalization. Despite continuous administration of LEV, tonic and myoclonic seizures relapsed within a month but her psychotic symptoms resolved simultaneously. To the best of our knowledge, this is the first reported case of forced normalization after LEV administration. It should be noted that LEV may cause forced normalization although it can be started at an adequate dosage.

    Intratumoral androgen biosynthesis has been recognized as an essential factor of castration-resistant prostate cancer. The present study investigated the effects of curcumin on the inhibition of intracrine androgen synthesis in prostate cancer. Human prostate cancer cell lines, LNCaP and 22Rv1 cells were incubated with or without curcumin after which cell proliferation was measured at 0, 24, 48 and 72 hours, respectively. Prostate tissues from the transgenic adenocarcinoma of the mouse prostate (TRAMP) model were obtained after 1-month oral administration of 200 mg/kg/d curcumin. Testosterone and dihydrotestosterone concentrations in LNCaP prostate cancer cells were determined through LC-MS/MS assay. Curcumin inhibited cell proliferation and induced apoptosis of prostate cancer cells in a dose-dependent manner. Curcumin decreased the expression of steroidogenic acute regulatory proteins, CYP11A1 and HSD3B2 in prostate cancer cell lines, supporting the decrease of testosterone production. After 1-month oral administration of curcumin, Aldo-Keto reductase 1C2 (AKR1C2) expression was elevated. Simultaneously, decreased testosterone levels in the prostate tissues were observed in the TRAMP mice. Meanwhile, curcumin treatments considerably increased the expression of AKR1C2 in prostate cancer cell lines, supporting the decrease of dihydrotestosterone. Taken together, these results suggest that curcumin's natural bioactive compounds could have potent anticancer properties due to suppression of androgen production, and this could have therapeutic effects on prostate cancer. © 2018 The Authors.

    Administration of intravenous therapy is a common occurrence within the hospital setting. Routine replacement of administration sets has been advocated to reduce intravenous infusion contamination. If decreasing the frequency of changing intravenous administration sets does not increase infection rates, a change in practice could result in considerable cost savings. The objective of this review was to identify the optimal interval for the routine replacement of intravenous administration sets when infusate or parenteral nutrition (lipid and non-lipid) solutions are administered to people in hospital via central or peripheral venous catheters. We searched The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, CINAHL, EMBASE: all from inception to February 2004; reference lists of identified trials, and bibliographies of published reviews. We also contacted researchers in the field. We did not have a language restriction. We included all randomized or quasi-randomized controlled trials addressing the frequency of replacing intravenous administration sets when parenteral nutrition (lipid and non-lipid containing solutions) or infusions (excluding blood) were administered to people in hospital via a central or peripheral catheter. Two authors assessed all potentially relevant studies. We resolved disagreements between the two authors by discussion with a third author. We collected data for the outcomes; infusate contamination; infusate-related bloodstream infection; catheter contamination; catheter-related bloodstream infection; all-cause bloodstream infection and all-cause mortality. We identified 23 references for review. We excluded eight of these studies; five because they did not fit the inclusion criteria and three because of inadequate data. We extracted data from the remaining 15 references (13 studies) with 4783 participants. We conclude that there is no evidence that changing intravenous administration sets more often than every 96 hours

    PURPOSE: Cognitive deficit after coronary artery bypass surgery (CABG) has a high prevalence and is persistent. Meta-analysis of clinical trials demonstrates a decreased incidence of stroke after CABG when aprotinin is administrated perioperatively. We hypothesized that aprotinin administration would decrease the incidence of cognitive deficit after CABG. METHODS: Thirty-six ASA III-IV patients undergoing elective CABG were included in a prospective, randomized, single-blinded pilot study. Eighteen patients received aprotinin 2 x 10(6) KIU (loading dose), 2 x 10(6) KIU (added to circuit prime) and a continuous infusion of 5 x 10(5) KIU.hr(-1). A battery of cognitive tests was administered to patients and spouses (n = 18) the day before surgery, four days and six weeks postoperatively. RESULTS: Four days postoperatively new cognitive deficit (defined by a change in one or more cognitive domains using the Reliable Change Index method) was present in ten (58%) patients in the aprotinin group compared to 17 (94%) in the placebo group [95% confidence interval (CI) 0.10-0.62, P = 0.005); (P = 0.01)]. Six weeks postoperatively, four (23%) patients in the aprotinin group had cognitive deficit compared to ten (55%) in the placebo group (95% CI 0.80-0.16, P = 0.005); (P = 0.05). CONCLUSION: In this prospective pilot study, the incidence of cognitive deficit after CABG and cardiopulmonary bypass is decreased by the administration of high-dose aprotinin.

    Employees make decisions every day about whether to contribute to others--and their willingness to help is crucial to group and organizational effectiveness. But in a competitive, often zero-sum, world of work, generosity can be a dangerous path. How can leaders foster it without cutting into productivity, undermining fairness, and allowing employees to become doormats? The key, explains Wharton's Adam Grant, is to help givers reach a more nuanced understanding of what generosity is and is not. They'll be better positioned for sustainable giving when they can distinguish generosity from three attributes that often travel with it: timidity, availability, and empathy. Givers can overcome timidity, Grant says, by learning to act as agents--using "relational accounts" to advocate for others while negotiating for themselves. They can set boundaries on when, how, and whom to help. And they can strive to be perspective takers, not just empathizers, gathering knowledge about others that can lead to more-productive allocations of time that will benefit the organization as a whole.

  9. Administration of antibiotics to ewes at the beginning of the dry-period.

    2014-02-01

    The objective of the present paper is to review the significance of administration of antibiotics at the end of a lactation period/beginning of the dry-period in ewes. During the stage of active involution, there is an increased risk of new mastitis cases and recrudescence of subclinical infections that had occurred during the previous lactation period. The main pathogens involved in the so-called 'dry-period mastitis' are coagulase-negative staphylococci. The principle of antibiotic administration at the end of a lactation period involves the intramammary infusion of a preparation to both mammary glands of ewes in the flock. Although a variety of products is licensed for administration in ewes, preferably the product for administration should be selected on the results of susceptibility testing of bacteria to be isolated from samples from ewes in the flock. In many clinical studies from around the world, performed in dairy- or mutton-production flocks, administration of antimicrobial agents at the end of a lactation period has been found beneficial in curing intramammary infections present at cessation of a lactation period, as well as in minimising the risk for intramammary infections during the dry-period. In dairy flocks, there are also benefits from increase in milk yield and decrease flock bulk milk mean somatic cell counts during the subsequent lactation period. Antibiotic administration at drying-off may be performed to all animals in a flock ('complete') or only to those considered to be infected ('selective'). In all cases, after administration of the antibiotic, definite and complete cessation of the lactation period is essential for success of the procedure. Moreover, maintenance of the prescribed withdrawal periods is essential to safeguard public health. The procedure should always be applied as part of a strategic udder health management plan in a flock; implementation improves the welfare of animals and affords significant financial benefits to the

    Full Text Available Fructose accumulates in tissue and body fluids of patients affected by hereditary fructose intolerance (HFI, a disorder caused by the deficiency of aldolase B. We investigated the effect of acute fructose administration on the biochemical profile and on the activities of the Krebs cycle enzymes in the cerebral cortex of young rats. Rats received a subcutaneous injection of NaCl (0.9 %; control group or fructose solution (5 μmol/g; treated group. Twelve or 24 h after the administration, the animals were euthanized and the cerebral cortices were isolated. Peripheral blood (to obtain the serum and cerebral spinal fluid (CSF from the animals were also collected. It was observed that albumin levels were decreased and cholesterol levels were increased in CSF of animals 12 h after the administration of fructose. In addition, serum lactate levels were increased 12 h after the administration, as compared to control group. Furthermore, malate dehydrogenase activity was increased in cerebral cortex from treated group 24 h after the administration of this carbohydrate. Herein we demonstrate that fructose administration alters biochemical parameters in CSF and serum and bioenergetics parameters in the cerebral cortex. These findings indicate a possible role of fructose on brain alterations found in HFI patients.

    Full Text Available Lying is a pervasive phenomenon with important social and economic implications. However, despite substantial interest in the prevalence and determinants of lying, little is known about its biological foundations. Here we study a potential hormonal influence, focusing on the steroid hormone testosterone, which has been shown to play an important role in social behavior. In a double-blind placebo-controlled study, 91 healthy men (24.32±2.73 years received a transdermal administration of 50 mg of testosterone (n=46 or a placebo (n=45. Subsequently, subjects participated in a simple task, in which their payoff depended on the self-reported outcome of a die-roll. Subjects could increase their payoff by lying without fear of being caught. Our results show that testosterone administration substantially decreases lying in men. Self-serving lying occurred in both groups, however, reported payoffs were significantly lower in the testosterone group (p<0.01. Our results contribute to the recent debate on the effect of testosterone on prosocial behavior and its underlying channels.

    Tauopathies are a group of disorders in which the cytosolic protein tau aggregates and accumulates in cells within the brain, resulting in neurodegeneration. A promising treatment being explored for tauopathies is passive immunization with anti-tau antibodies. We previously found that administration of an anti-tau antibody to human tau transgenic mice increased the concentration of plasma tau. We further explored the effects of administering an anti-tau antibody on plasma tau. After peripheral administration of an anti-tau antibody to human patients with tauopathy and to mice expressing human tau in the central nervous system, there was a dose-dependent increase in plasma tau. In mouse plasma, we found that tau had a short half-life of 8 min that increased to more than 3 hours after administration of anti-tau antibody. As tau transgenic mice accumulated insoluble tau in the brain, brain soluble and interstitial fluid tau decreased. Administration of anti-tau antibody to tau transgenic mice that had decreased brain soluble tau and interstitial fluid tau resulted in an increase in plasma tau, but this increase was less than that observed in tau transgenic mice without these brain changes. Tau transgenic mice subjected to acute neuronal injury using 3-nitropropionic acid showed increased interstitial fluid tau and plasma tau. These data suggest that peripheral administration of an anti-tau antibody results in increased plasma tau, which correlates with the concentration of extracellular and soluble tau in the brain.

Hopes and wishes were rising when he was elected as the president of Indonesia. This paper will describe various innovations undertaken before and after his presidential inauguration as well as the assorted innovations made in reforming the administration of his cabinet. As the president of Indonesia, Joko Widodo is required to realize the aspirations of the people in freeing the government from corruption, collusion, and nepotism. The management of ministerial and non-ministerial institutions becomes the very first crucial issue undertaken by Joko Widodo. This led to a polemic in regards to reducing or increasing the number of institutions, as the Jokowi administration actually increased the amount. In Susilo Bambang Yudhoyono's administration, several policies were made systematically and based on legislations that had been approved by the lagislature. Joko Widodo's administration in more partial in nature. The administrative reform program that is highly anticipated is the continuation of the Public Service Act. This law is a step forward from the administrative reform program that aims at the creation of good governance. Changes is career path, salary system, pension and benefits for civil servants, performance-based staffing are various efforts of sustainability carried out by Joko Widodo's administration.

    Dextromethorphan is recognized as a substance of abuse around the world. An estimated 3.1 million people between the ages of 12 and 25 years (5.3%) misused over-the-counter cough and cold medications in 2006. In this study, we developed a serum metabolomic method by gas chromatography-mass spectrometry (GC-MS) to evaluate the effect of abuse of dextromethorphan on rats. The dextromethorphan-treated rats were given 12, 24 and 48 mg/kg (low, medium, high) of dextromethorphan by intragastric administration each day for 3 days. Partial least squares-discriminate analysis revealed that intragastric administration of dextromethorphan induced metabolic perturbations. Compared with the control (healthy) group, the levels of propanoic acid, urea, heptafluorobutanoic acid, 2-hexyldecanoic acid and butanedioic acid of the low group decreased; levels of propanoic acid and heptafluorobutanoic acid of the medium group decreased, while that of benzoic acid increased; and levels of 2-hexyldecanoic acid, glycerol and butanedioic acid of the high group increased. These biomarkers are involved in the citric acid cycle, urea cycle, glycerolipid metabolism and tricarboxylic acid cycle. The results indicate that the metabolomic method by GC-MS may be useful to elucidate abuse of dextromethorphan. According to the pathological changes in the liver at different dosages, dextromethorphan is not hepatotoxic after intragastric administration of 12, 24 and 48 mg/kg for 3 days.

    Full Text Available Intraperitoneal (i.p. administration of small interfering RNA (siRNA has, to date, shown promise in treating tumours located within the peritoneal cavity. The ability of these siRNA molecules to reach extraperitoneal tumours following i.p. administration is, however, yet to be investigated. Here, we examined the impact of PEGylation on the biodistribution of i.p. administered nucleic acids-containing lipoplexes. We showed that in contrast to non-PEGylated liposomes, PEGylated liposomes can deliver siRNA efficiently to extraperitoneal tumours following i.p. administration, resulting in a 45% reduction in tumour size when the oncogene-targeted siRNA was used. This difference was likely contributed by the decreased uptake of PEGylated lipoplexes in the first-pass organs, and, in particular, we observed a 10-fold decrease in the macrophage uptake of these particles compared to non-PEGylated counterparts. Overall, our results indicated the potential of using PEGylated liposomes to deliver siRNA for the treatment of i.p. localized cancer with coexisting extraperitoneal metastasis.

    Full Text Available Over the past few years, Public Administrations have been providing systems for procedures and files electronic processing to ensure compliance with regulations and provide public services to citizens. Although each administration provides similar services to their citizens, these systems usually differ from the internal information management point of view since they usually come from different products and manufacturers. The common framework that regulations demand, and that Public Administrations must respect when processing electronic files, provides a unique opportunity for the development of intelligent agents in the field of administrative processes. However, for this development to be truly effective and applicable to the public sector, it is necessary to have a common representation model for these administrative processes. Although a lot of work has already been done in the development of public information reuse initiatives and common vocabularies standardization, this has not been carried out at the processes level. In this paper, we propose a semantic representation model of both processes models and processes for Public Administrations: the procedures and administrative files. The goal is to improve public administration open data initiatives and help to develop their sustainability policies, such as improving decision-making procedures and administrative management sustainability. As a case study, we modelled public administrative processes and files in collaboration with a Regional Public Administration in Spain, the Principality of Asturias, which enabled access to its information systems, helping the evaluation of our approach.

  20. A Logic for Inclusion of Administrative Domains and Administrators in Multi-domain Authorization

    Authorization policies for an administrative domain or a composition of multiple domains in multi-domain environments are determined by either one administrator or multiple administrators' cooperation. Several logic-based models for multi-domain environments' authorization have been proposed; however, they have not considered administrators and administrative domains in policies' representation. In this paper, we propose the syntax, proof theory, and semantics of a logic for multi-domain authorization policies including administrators and administrative domains. Considering administrators in policies provides the possibility of presenting composite administration having applicability in many collaborative applications. Indeed, administrators and administrative domains stated in policies can be used in authorization. The presented logic is based on modal logic and utilizes two calculi named the calculus of administrative domains and the calculus of administrators. It is also proved that the logic is sound. A case study is presented signifying the logic application in practical projects.

    Full Text Available Abstract Background Beta-adrenergic receptor agonists (BA induce skeletal muscle hypertrophy, yet specific mechanisms that lead to this effect are not well understood. The objective of this research was to identify novel genes and physiological pathways that potentially facilitate BA induced skeletal muscle growth. The Affymetrix platform was utilized to identify gene expression changes in mouse skeletal muscle 24 hours and 10 days after administration of the BA clenbuterol. Results Administration of clenbuterol stimulated anabolic activity, as indicated by decreased blood urea nitrogen (BUN; P P Conclusion Global evaluation of gene expression after administration of clenbuterol identified changes in gene expression and overrepresented functional categories of genes that may regulate BA-induced muscle hypertrophy. Changes in mRNA abundance of multiple genes associated with myogenic differentiation may indicate an important effect of BA on proliferation, differentiation, and/or recruitment of satellite cells into muscle fibers to promote muscle hypertrophy. Increased mRNA abundance of genes involved in the initiation of translation suggests that increased levels of protein synthesis often associated with BA administration may result from a general up-regulation of translational initiators. Additionally, numerous other genes and physiological pathways were identified that will be important targets for further investigations of the hypertrophic effect of BA on skeletal muscle.

    Heparin produces changes in FT 4 -levels both in vivo and in vitro as determined by commercial kits. Methods utilising the principle of equilibrium dialysis show significant increases whereas methods using T 4 -tracer analogue techniques reveal marked decreases in FT 4 -values. Possible clinical side-effects of heparin administration such as heparin-induced hyperthyroidism and tachyarrhythmias are discussed. The present results confirm the FT 4 -decreasing effect of in vivo and in vitro administration of heparin with FT 4 -RIAs based on the tracer analogue technique; however, the unspecific peripheral thyroid parameter of systolic time-intervals did not reveal any tendency towards hyperthyroidism. Also the discrepant results dependent on the method used, indicate that, following heparin administration FT 4 -levels do not reflect that hormone concentration is relevant to the metabolism of the whole body.

    Acetaldehyde (ACD), the first metabolite of ethanol, has been implicated in several behavioural actions of alcohol, including its reinforcing effects. Recently, we reported that l-cysteine, a sequestrating agent of ACD, reduced oral ethanol self-administration and that ACD was orally self-administered. This study examined the effects of l-cysteine pre-treatment during the acquisition and maintenance phases of ACD (0.2%) self-administration as well as on the deprivation effect after ACD extinction and on a progressive ratio (PR) schedule of reinforcement. In a separate PR schedule of reinforcement, the effect of l-cysteine was assessed on the break-point produced by ethanol (10%). Furthermore, we tested the effect of l-cysteine on saccharin (0.2%) reinforcement. Wistar rats were trained to self-administer ACD by nose poking on a fixed ratio (FR1) schedule in 30-min daily sessions. Responses on an active nose-poke caused delivery of ACD solution, whereas responses on an inactive nose-poke had no consequences. l-cysteine reduced the acquisition (40 mg/kg), the maintenance and the deprivation effect (100 mg/kg) of ACD self-administration. Furthermore, at the same dose, l-cysteine (120 mg/kg) decreased both ACD and ethanol break point. In addition, l-cysteine was unable to suppress the different responses for saccharin, suggesting that its effect did not relate to an unspecific decrease in a general motivational state. Compared to saline, l-cysteine did not modify responses on inactive nose-pokes, suggesting an absence of a non-specific behavioural activation. Taken together, these results could support the hypotheses that ACD possesses reinforcing properties and l-cysteine reduces motivation to self-administer ACD. Copyright © 2012 Elsevier Inc.

    Background Exercise influences drug craving and consumption in humans and drug self-administration in laboratory animals, but the effects can be variable. Improved understanding of how exercise affects drug intake or craving would enhance applications of exercise programs to human drug users attempting cessation. Methods Rats were trained in the intravenous self-administration (IVSA) of d-methamphetamine (METH; 0.05 mg/kg/inf), 3,4-methylenedioxymethamphetamine (MDMA; 0.5 mg/kg/inf) or methylone (0.5 mg/kg/inf). Once IVSA was established, the effect of ~22 hrs of wheel access in the home cage on subsequent drug taking was assessed in a two cohort crossover design. Results Provision of home cage wheel access during the day prior to IVSA sessions significantly decreased the self-administration of METH, MDMA and methylone. At the individual level, there was no correlation between the amount a rat used the wheel and the size of the individual’s decrease in drug intake. Conclusions Wheel access can reduce self-administration of a variety of psychomotor stimulants. It does so immediately, i.e., without a need for weeks of exercise prior to drug access. This study therefore indicates that future mechanistic investigations should focus on acute effects of exercise. In sum, the results predict that exercise programs can be used to decrease stimulant drug use in individuals even with no exercise history and an established drug taking pattern. PMID:25863714

    The objective of this study was to assess the effects of a continuous overnight infusion of des-acyl ghrelin (DAG) on acylated ghrelin (AG) levels and glucose and insulin responses to a standard breakfast meal (SBM) in eight overweight patients with type 2 diabetes. Furthermore, in the same patients and two additional subjects, the effects of DAG infusion on AG concentrations and insulin sensitivity during a hyperinsulinemic-euglycemic clamp (HEC) were assessed. A double-blind, placebo-controlled cross-over study design was implemented, using overnight continuous infusions of 3 and 10  μg DAG/kg per h and placebo to study the effects on a SBM. During a HEC, we studied the insulin sensitivity. We observed that, compared with placebo, overnight DAG administration significantly decreased postprandial glucose levels, both during continuous glucose monitoring and at peak serum glucose levels. The degree of improvement in glycemia was correlated with baseline plasma AG concentrations. Concurrently, DAG infusion significantly decreased fasting and postprandial AG levels. During the HEC, 2.5  h of DAG infusion markedly decreased AG levels, and the M-index, a measure of insulin sensitivity, was significantly improved in the six subjects in whom we were able to attain steady-state euglycemia. DAG administration was not accompanied by many side effects when compared with placebo. DAG administration improves glycemic control in obese subjects with type 2 diabetes through the suppression of AG levels. DAG is a good candidate for the development of compounds in the treatment of metabolic disorders or other conditions with a disturbed AG:DAG ratio, such as type 2 diabetes mellitus or Prader-Willi syndrome. © 2014 European Society of Endocrinology.

  7. Case of administrative dispute

    2015-11-01

    Full Text Available The activity of administrative bodies includes big numbers of various acts and actions, through which the will of public administration is formed. The will of public administration bodies, expressed in administrative individual and normative acts, in administrative contracts and real acts, finds its reflection in the Constitution, laws and other provisions of legal character. All this activity is not inerrant and therefore, it is not uncontrollable. The supervision of executive activity is subject to political control of administrative acts through authorities designated for this purpose, as well as internal control and the judicial control. The institution of judicial control of administrative acts and actions appears as very important and widely treated in the legal doctrine. The protection of constitutional and legal rights of private persons is accomplished by subjecting administrative activity both to internal administrative control, as well as to the judicial control in accordance with legal provisions. The judicial control of administrative acts represents a constitutional guarantee for citizens to protect their rights through public and fair trial by an independent and impartial court. In this way, the Constitution empowers the common administrative court that invalidates an action or administrative act, but not all administrative acts may be subject to administrative dispute, with the exception of cases against which the administrative conflict cannot be carried out (negative enumeration.

    The current study aimed to elucidate the role of pharmacokinetic (PK) parameters and neurotransmitter efflux in explaining variability in (±) 3, 4-methylenedioxymethamphetamine (MDMA) self-administration in rats. PK profiles of MDMA and its major metabolites were determined after the administration of 1.0 mg/kg MDMA (iv) prior to, and following, the acquisition of MDMA self-administration. Synaptic levels of 5-hydroxytryptamine (5HT) and dopamine (DA) in the nucleus accumbens were measured following administration of MDMA (1.0 and 3.0 mg/kg, iv) using in vivo microdialysis and compared for rats that acquired or failed to acquire MDMA self-administration. Effects of the 5HT neurotoxin, 5,7 dihydroxytryptamine (5, 7-DHT), on the acquisition of MDMA and cocaine self-administration were also determined. In keeping with previous findings, approximately 50% of rats failed to meet a criterion for acquisition of MDMA self-administration. The PK profiles of MDMA and its metabolites did not differ between rats that acquired or failed to acquire MDMA self-administration. MDMA produced more overflow of 5HT than DA. The MDMA-induced 5HT overflow was lower in rats that acquired MDMA self-administration compared with those that did not acquire self-administration. In contrast, MDMA-induced DA overflow was comparable for the two groups. Prior 5,7-DHT lesions reduced tissue levels of 5HT and markedly increased the percentage of rats that acquired MDMA self-administration and also decreased the latency to acquisition of cocaine self-administration. These data suggest that 5HT limits the initial sensitivity to the positively reinforcing effects of MDMA and delays the acquisition of reliable self-administration. © 2013 Society for the Study of Addiction.

    Stress-induced neuroendocrine activities influence the regulation of endocrine glands and axes. Weight loss-related hypothalamic amenorrhea is a typical stress-induced physiopathological condition. It is characterized by increased adrenal cortex activation and by reduced GH, LH, FSH and gonadal steroid hormone levels. The aim of the present study was to investigate the effects of pivagabine, a neurotropic drug (1800 mg/day for 7 days) or placebo administration on ACTH, cortisol, GH, LH, FSH and PRL plasma levels in patients with hypothalamic amenorrhea related to weight loss. Hormonal parameters and the pulsatile release of cortisol (6-hour pulsatility, sampling every 10 minutes) were evaluated before and after 7 days of treatment. Pivagabine administration significantly reduced mean plasma ACTH (from 21.7+/-1.7 to 15.4+/-1.2 pg/ml, p<0.05) and cortisol levels (from 12.2+/-0.7 to 9.7+/-0.7 ng/ml, p<0.05) and increased GH levels (from 1.4+/-0.5 to 3.0+/-0.9 ng/ml, p<0.05). A significant reduction of cortisol pulse amplitude was observed (p<0.01) while no change in pulse frequency occurred. No changes were observed in placebo-treated subjects. LH, FSH and PRL levels were not modified by placebo or pivagabine administration. In conclusion, in patients with hypothalamic amenorrhea related to weight loss pivagabine induced a significant decrease of cortisol secretion and an increase of GH release by pivagabine administration, suggesting that this drug exerts a specific neuroendocrine modulatory role.

    Illicit and therapeutic opioid administration can result in overdose due to opioid-induced respiratory depression. Research investigating the respiratory depressant effects of opioids has been limited due to difficulties associated with acquiring long-term respiratory data. This study examined the novel use of radiotelemetry to measure respiratory rate, heart rate, locomotor activity and blood pressure in rats treated chronically with methadone. Over 4 days of treatment, respiratory rate decreased, but partial tolerance appeared to develop during active (night) periods. Decreased heart rate was observed during the night periods and tolerance appeared to develop to this effect. Activity and blood pressure did not change with treatment. The effects of naloxone hydrochloride and naloxone methiodide administration on the methadone-treated rats were also examined and both antagonists increased respiratory rate and heart rate, with only naloxone hydrochloride producing significant increases in activity. Radiotelemetry offers a means of evaluating drug effects on respiratory rate continually in ambulatory, unstressed animals.

    Studies demonstrated that chronic high-dose homocysteine administration induced learning and memory impairment in animals. Atractylenolide III (Aen-III), a neuroprotective constituent of Atractylodis macrocephalae Koidz, was isolated in our previous study. In this study, we investigated potential benefits of Aen-III in preventing learning and memory impairment following chronic high-dose homocysteine administration in rats. Results showed that administration of Aen-III significantly ameliorated learning and memory impairment induced by chronic high-dose homocysteine administration in rats, decreased homocysteine-induced reactive oxygen species (ROS) formation and restored homocysteine-induced decrease of phosphorylated protein kinase C expression level. Moreover, Aen-III protected primary cultured neurons from apoptotic death induced by homocysteine treatment. This study provides the first evidence for the neuroprotective effect of Aen-III in preventing learning and impairment induced by chronic administration of homocysteine. Aen-III may have therapeutic potential in treating homocysteine-mediated cognitive impairment and neuronal injury. Copyright © 2015 IBRO. Published by Elsevier Ltd. All rights reserved.

    2011-10-01

    To characterize pharmacokinetics and pharmacodynamics of detomidine gel administered sublingually in accordance with label instructions to establish appropriate withdrawal guidelines for horses before competition. 12 adult racehorses. Horses received a single sublingual administration of 0.04 mg of detomidine/kg. Blood samples were collected before and up to 72 hours after drug administration. Urine samples were collected for 5 days after detomidine administration. Plasma and urine samples were analyzed via liquid chromatography-mass spectrometry, and resulting data were analyzed by use of noncompartmental analysis. Chin-to-ground distance, heart rate and rhythm, glucose concentration, PCV, and plasma protein concentration were also assessed following detomidine administration. Mean ± SD terminal elimination half-life of detomidine was 1.5 ± 1 hours. Metabolite concentrations were below the limit of detection (0.02, 0.1, and 0.5 ng/mL for detomidine, carboxydetomidine, and hydroxydetomidine, respectively) in plasma by 24 hours. Concentrations of detomidine and its metabolites were below the limit of detection (0.05 ng/mL for detomidine and 0.10 ng/mL for carboxydetomidine and hydroxydetomidine) in urine by 3 days. All horses had various degrees of sedation after detomidine administration. Time of onset was ≤ 40 minutes, and duration of sedation was approximately 2 hours. Significant decreases, relative to values at time 0, were detected for chin-to-ground distance and heart rate. There was an increased incidence and exacerbation of preexisting atrioventricular blocks after detomidine administration. A 48-hour and 3-day withdrawal period for detection in plasma and urine samples, respectively, should be adopted for sublingual administration of detomidine gel.

  16. Oral administration of insulin by means of liposomes in animal experiments

    Tragl, K.H.; Pohl, A.; Kinast, H.

    1979-01-01

    Liposomes are an effective vehicle for the oral administration of insulin. They are prepared from lipid emulsions by sonication and particles of homogeneous size are generated by elution through sepharose columns. Liposomes are taken up into the gastric mucosa by endocytosis and then transported to the liver via the portal circulation. Oral administration of 10 U insulin/kg body weight to rats is followed by a reduction in blood glucose to 67% of the initial value. When liposome-trapped insulin was injected intravenously a decrease in blood glucose to 40% of the initial value was obtained by the administration of 5 IU insulin/kg body weight. While the effect of orally-administered liposome-trapped insulin is obvious, the problems of standardization of the insulin content of the liposomes and the great variability of liposome uptake into the gastric mucosa by endocytosis remain unsolved.

    To determine the distribution of terbinafine in the cornea and aqueous humor after topical administration. A corn oil ointment of terbinafine 0.2% (resolved in sterile corn oil) was applied to the conjunctival sac of albino rabbits twice (with a 5-min interval). The concentration of terbinafine was determined with high-performance liquid chromatography (HPLC) 5, 15, 30, 60, 120 and 240 min after administration of terbinafine. After topical administration, the concentration of terbinafine increased gradually, reached a peak (1.39 microg/ml at 30 min in the cornea and 82.9 ng/ml at 30 min in aqueous humor, respectively) and then decreased. The concentration was 0.18 microg/g at 240 min in the cornea, but terbinafine could not be tested at 120 min in aqueous humor. Topical ophthalmic terbinafine 0.2% could penetrate into the cornea and aqueous humor at concentrations adequate for inhibition of fungus.

    The decarboxylation product of arginine, agmatine, has effectively reduced or prevented opioid-induced tolerance and dependence when given either systemically (intraperitoneally or subcutaneously) or centrally (intrathecally or intracerebroventricularly). Systemically administered agmatine also reduces the escalation phase of intravenous fentanyl self-administration in rats. The present study assessed whether centrally (intracerebroventricular, i.c.v.) delivered agmatine could prevent the development of fentanyl self-administration in mice. Mice were trained to respond under a fixed-ratio 1 (FR1) schedule for either fentanyl (0.7 μg/70 μl, p.o.) or food reinforcement. Agmatine (10 nmol/5 μl), injected i.c.v. 12-14h before the first session and every other evening (12-14h before session) for 2 weeks, completely attenuated oral fentanyl self-administration (but not food-maintained responding) compared to saline-injected controls. When agmatine was administered after fentanyl self-administration had been established (day 8) it had no attenuating effects on bar pressing. This dose of agmatine does not decrease locomotor activity as assessed by rotarod. The present findings significantly extend the previous observation that agmatine prevents opioid-maintained behavior to a chronic model of oral fentanyl self-administration as well as identifying a supraspinal site of action for agmatine inhibition of drug addiction.

    Administration of kainic acid evokes acute seizure in hippocampal pathways that results in a complex sequence of functional and structural alterations resembling human temporal lobe epilepsy. The structural alterations induced by kainic acid include selective loss of neurones in CA1-CA3 subfields and the hilar region of the dentate gyrus followed by sprouting and permanent reorganization of the synaptic connections of the mossy fibre pathways. Although the neuronal degeneration and process of reactive synaptogenesis have been extensively studied, at present little is known about means to prevent pathological conditions leading to kainate-induced cell death. In the present study, to address the role of insulin-like growth factors I and II, and insulin in neuronal survival as well as synaptic reorganization following kainate-induced seizure, the time course alterations of the corresponding receptors were evaluated. Additionally, using histological preparations, the temporal profile of neuronal degeneration and hypertrophy of resident astroglial cells were also studied. [ 125 I]Insulin-like growth factor I binding was found to be decreased transiently in almost all regions of the hippocampal formation at 12 h following treatment with kainic acid. The dentate hilar region however, exhibited protracted decreases in [ 125 I]insulin-like growth factor I receptor sites throughout (i.e. 30 days) the study. [ 125 I]Insulin-like growth factor II receptor binding sites in the hippocampal formation were found to be differentially altered following systemic administration of kainic acid. A significant decrease in [ 125 I]insulin-like growth factor II receptor sites was observed in CA1 subfield and the pyramidal cell layer of the Ammon's horn at all time points studied whereas the hilar region and the stratum radiatum did not exhibit alteration at any time. A kainate-induced decrease in [ 125 I]insulin receptor binding was noted at all time points in the molecular layer of the

It is not intended to replace the Ultrix Documentation Set that should be available for a DCPS installation. The Ultrix Documentation Set will be required to provide details on referenced Ultrix commands as well as procedures for performing Ultrix maintenance functions. There are six major sections in this guide. Section 1 introduces the system administrator to CDPS and describes the assumptions that are made by this guide. Section 2 describes the CDPS platform configuration. Section 3 describes the platform preparation that is required to install the CDPS software. Section 4 describes the CPS software and its installation procedures. Section 5 describes the CDS software and its installation procedures. Section 6 describes various operation and maintenance procedures. Four appendices are also provided. Appendix A contains a list of used acronyms. Appendix B provides a terse description of common Ultrix commands that are used in administrative functions. Appendix C provides sample CPS and CDS configuration files. Appendix D provides a required list and a recommended list of Ultrix software subsets for installation on a CDPS platform.

    Preventive chemotherapy with praziquantel for schistosomiasis morbidity control is commonly done by mass drug administration (MDA). MDA regimen is usually based on prevalence in a given area, and effectiveness is evaluated by decreases in prevalence and/or intensity of infection after several years of implementation. Multiple studies and programs now find that even within well-implemented, multiyear, annual MDA programs there often remain locations that do not decline in prevalence and/or intensity to expected levels. We term such locations "persistent hotspots." To study and address persistent hotspots, investigators and neglected tropical disease (NTD) program managers need to define them based on changes in prevalence and/or intensity. But how should the data be analyzed to define a persistent hotspot? We have analyzed a dataset from an operational research study in western Tanzania after three annual MDAs using four different approaches to define persistent hotspots. The four approaches are 1) absolute percent change in prevalence; 2) percent change in prevalence; 3) change in World Health Organization guideline categories; 4) change (absolute or percent) in both prevalence and intensity. We compare and contrast the outcomes of these analyses. Our intent is to show how the same dataset yields different numbers of persistent hotspots depending on the approach used to define them. We suggest that investigators and NTD program managers use the approach most suited for their study or program, but whichever approach is used, it should be clearly stated so that comparisons can be made within and between studies and programs.

    Low serotonin function is associated with alcoholism, leading to speculation that increasing serotonin function could decrease ethanol consumption. Mice with one or two deletions of the serotonin transporter (SERT) gene have increased extracellular serotonin. To examine the relationship between SERT genotype and motivation for alcohol, we compared ethanol self-administration in mice with zero (knockout, KO), one (HET) or two copies (WT) of the SERT gene. All three genotypes learned to self-administer ethanol. The SSRI, fluvoxamine, decreased responding for ethanol in the HET and WT, but not the KO mice. When tested under a progressive ratio schedule, KO mice had lower breakpoints than HET or WT. As work requirements were increased across sessions, behavioral economic analysis of ethanol self-administration indicated that the decreased breakpoint in KO as compared to HET or WT mice was a result of lower levels of unconstrained demand, rather than differences in elasticity, i.e. the proportional decreases in ethanol earned with increasing work requirements were similar across genotypes. The difference in unconstrained demand was unlikely to result from motor or general motivational factors, as both WT and KO mice responded at high levels for a 50% condensed milk solution. As elasticity is hypothesized to measure essential value, these results indicate that KO value ethanol similarly to WT or HET mice despite having lower break points for ethanol. © 2013 John Wiley & Sons Ltd and International Behavioural and Neural Genetics Society.

    Aflatoxins are mycotoxins that have important toxic effects on human and animal health, even if consumed at low doses. The oral administration of piperine (1.12 mg/kg) during 23 days in rats seemingly interfered with the toxicity of aflatoxins, decreasing hepatic injuries and the leukocyte depletion in experimentally intoxicated animals.

    The tubing (administration set) attached to both venous and arterial catheters may contribute to bacteraemia and other infections. The rate of infection may be increased or decreased by routine replacement of administration sets. This review was originally published in 2005 and was updated in 2012. The objective of this review was to identify any relationship between the frequency with which administration sets are replaced and rates of microbial colonization, infection and death. We searched The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 6), MEDLINE (1950 to June 2012), CINAHL (1982 to June 2012), EMBASE (1980 to June 2012), reference lists of identified trials and bibliographies of published reviews. The original search was performed in February 2004. We also contacted researchers in the field. We applied no language restriction. We included all randomized or controlled clinical trials on the frequency of venous or arterial catheter administration set replacement in hospitalized participants. Two review authors assessed all potentially relevant studies. We resolved disagreements between the two review authors by discussion with a third review author. We collected data for seven outcomes: catheter-related infection; infusate-related infection; infusate microbial colonization; catheter microbial colonization; all-cause bloodstream infection; mortality; and cost. We pooled results from studies that compared different frequencies of administration set replacement, for instance, we pooled studies that compared replacement ≥ every 96 hours versus every 72 hours with studies that compared replacement ≥ every 48 hours versus every 24 hours. We identified 26 studies for this updated review, 10 of which we excluded; six did not fulfil the inclusion criteria and four did not report usable data. We extracted data from the remaining 18 references (16 studies) with 5001 participants: study designs included neonate and adult

    Autophagy plays an important role in alleviating oxidative stress and stabilizing atherosclerotic plaques. However, the potential role of autophagy in endothelial vasodilation function has rarely been studied. This study aimed to investigate whether rhynchophylla total alkaloid (RTA) has a positive role in enhancing autophagy through decreasing oxidative stress, and improving endothelial vasodilation. In oxidized low-density lipoprotein (ox-LDL)-treated human umbilical vein endothelial cells (HUVECs), RTA (200 mg/L) significantly suppressed ox-LDL-induced oxidative stress through rescuing autophagy, and decreased cell apoptosis. In spontaneous hypertensive rats (SHR), administration of RTA (50 mg·kg -1 ·d -1 , ip, for 6 weeks) improved endothelin-dependent vasodilation of thoracic aorta rings. Furthermore, RTA administration significantly increased the antioxidant capacity and alleviated oxidative stress through enhancing autophagy in SHR. In ox-LDL-treated HUVECs, we found that the promotion of autophagy by RTA resulted in activation of the AMP-activated protein kinase (AMPK) signaling pathway. Our results show that RTA treatment rescues the ox-LDL-induced autophagy impairment in HUVECs and improves endothelium-dependent vasodilation function in SHR.

Melatonin (MEL, 4 μg/ml of tap water was administered daily since the 5th week of age. The control group drank tap water. Rats were fed a standard type of diet ad libitum and were kept in the light regimen L:D - 12:12 h. The experiment was terminated after 11 (variant B or 12 (variant A weeks of MEL administration. The animals were sacrificed by quick decapitation following overnight fasting (variant A or 48-h fasting (variant B. Selected organs and tissues were removed and weighed and selected metabolic variables in the serum and tissues were determined. MEL decreased body mass independent of food and water intake in both sexes. In males (variant A MEL increased the weight of the heart muscle, spleen and adrenals; it decreased the absolute weight of epididymal fat and increased serum corticosterone and phospholipids concentration in comparison with controls. In females, serum glucose decrease and liver triacylglycerols increase were found. After 48-h fasting (variant B liver, spleen and adrenal weight increase in MELdrinking females was found. In males MEL increased the thymus weight and decreased the epididymal fat weight. In both sexes MEL increased serum corticosterone and liver glycogen concentration; MEL increased serum glucose in males and serum cholesterol concentration in females. Changes in the evaluated variables were also related to fasting duration prior to decapitation. A 48-h fasting at the end of the prolonged MEL intake (variant B vs. A decreased the absolute liver weight in both sexes and the epididymal/periovarial fat weight, and increased thymus weight in males. In females it decreased the absolute heart muscle weight and increased the spleen weight. In males, 48-h fasting increased serum corticosterone and phospholipids concentration; it

    Daiokanzoto (DKT) exerts its laxative effect via colonic inflammation caused by sennoside A in Daio (rhubarb). Previously, we showed that the laxative effect of sennoside A is related to decreased aquaporin-3 (AQP3) expression in mucosal epithelial cells due to colonic inflammation. We also found that a combination of glycyrrhizin, an ingredient in Kanzo (glycyrrhiza), and sennoside A attenuates the inflammatory response induced by sennoside A and reduces its laxative effect. These findings indicate that DKT may be a long-term treatment for chronic constipation, but there is no evidence supporting this hypothesis. In this study, we analyzed the laxative effect of repeated DKT administration, focusing on AQP3 expression in the colon. After rats were treated for 7 days, decreased AQP3 expression and the onset of diarrhea were observed in the DKT group, but were not seen in the Daio group either. Although the relative abundance of gut microbiota after repeated DKT administration was similar to that after control treatment, Daio reduced Lactobacillaceae, Bifidobacteriaceae, and Bacteroidaceae levels and markedly increased Lachnospiraceae levels. In this study, we show that DKT has a sustained laxative effect, even upon repeated use, probably because it maintains decreased AQP3 expression and gut microbiota homeostasis. This outcome therefore indicates that DKT can be used as a long-term treatment for chronic constipation.

    Aim: The aim of this investigation is to study biokinetics from internally 131 I deposited for thyroid cancer patients during radioiodine therapy (2 to 3 days), after ablation dose administration (3.7 GBq). These data will help in the elaboration of a metabolic model, which will permit absorbed dose assessment for this specific case, since the biokinetic models for iodine available in scientific literature can not be applied to thyroidectomized patient's studies. Material and Methods: Four females patients, between 22 and 50 years old, without metastases, between 1.9 to 6% of remnant thyroid tissue uptake, agreed to contribute to this study. For the in vivo bioassay, periodical measurements were performed along internment time (2 to 3 days), just after Na 131 I dose administration (3.7 GBq). For this, we used the counting system for Nuclear Medicine model 13S002, IEN/CNEN- Brazil, which was adapted with lead filters, in order to allow the work with high rate counting. The measurements were performed in two geometries: thyroid region and thigh. Results: For each patient, we have done approximately 26 measurements for both geometries, starting at the first hour following dose administration until the release from hospital of patient. The results of counting rate (cps) were plotted against time (h). The measurements suggest a relation between remnant thyroid tissue uptake values and the time where counting rates start decreasing. In addition, it was observed a correlation between remnant thyroid tissue radioactive burdens and the circulating iodine through time. Conclusion: It is necessary to follow-up a greater number of patients aiming to confirm the observed correlations and with a greater number of measurements during the first 24 hours, in other to delimit the time range of increasing and decreasing counting rate

    Excessive consumption of fat and fructose leads to obesity due to lipid accumulation. The excessive lipid causes hypertrophy in the adipocytes which lead to cell death. Consequently, dead adipocytes will produce adipokines, which cause macrophages and lymphocytes to infiltrate into the adipose tissue, elevating pro-inflammatory cytokines, thus triggering the production of pro-inflammatory cytokines through NFκB activity. Elicited soybeans extract (ESE) with bacteria and light contain Glyceollin and Isoflavones, which inhibit the activation of NFKB and reduce plasma cholesterol levels by upregulating cholesterol metabolism. This study aimed to analyze the effect of ESE against the relative number of CD4+ NFκB+ cells in BALB/c mice spleen after administrated by high-fat diet food and fructose (HFD) for 20 weeks. Mice were given orally with ESE after administrated by HFD at dose 78 mg/kgBW (D1), 104 mg/kgBW (D2), and 130 mg/kgBW (D3) for 4 weeks. This study also used positive control (HFD mice model without ESE treatment) and normal mice. Identification of NFKB activation was conducted using Flowcytometry analytical methods. Our result indicated that ESE could decrease significantly activation of NFκB in CD4 cell compare than positive control. The optimum dose that can decrease the relative number of CD4+ NFκB+ cells is dose 3.

    Full Text Available The aim of the study was to determine the variations of function in components of monooxygenase system (MOS of rat Guerin’s carcinoma under ω-3 polyunsaturated fatty acids (PUFAs administration. The activity of Guerin’s carcinoma microsomal NADH-cytochrome b5 reductase, the content and the rate of cytochrome b5 oxidation-reduction, the content and the rate of cytochrome Р450 oxidation-reduction have been investigated in rats with tumor under conditions of ω-3 PUFAs administration. ω-3 PUFAs supplementation before and after transplantation of Guerin’s carcinoma resulted in the increase of NADH-cytochrome b5 reductase activity and decrease of cytochrome b5 level in the Guerin’s carcinoma microsomal fraction in the logarithmic phases of carcinogenesis as compared to the tumor-bearing rats. Increased activity of NADH-cytochrome b5 reductase facilitates higher electron flow in redox-chain of MOS. Under decreased cytochrome b5 levels the electrons are transferred to oxygen, which leads to heightened generation of superoxide (O2•- in comparison to control. It was shown, that the decrease of cytochrome P450 level in the Guerin’s carcinoma microsomal fraction in the logarithmic phases of oncogenesis under ω-3 PUFAs administration may be associated with its transition into an inactive form – cytochrome P420. This decrease in cytochrome P450 coincides with increased generation of superoxide by MOS oxygenase chain.

    To understand the constant increase in administration, we need a new approach to the administration. For many years, the administration has intensified as a closed science, associated only with economics, law and political science. However, this approach did not bring anything good, because almost nothing in the administration has improved. Therefore, it is necessary to connect the administration with the natural sciences which give the best description of the world around us. Because of this...

    Increased oxidative stress, which can lead to the retinal pigment epithelium (RPE) cell death by inducing ATP depletion and DNA repair, is believed to be a prominent pathology in age-related macular degeneration (AMD). In the present study, we showed that and 0.1 mM nicotinamide adenine dinucleotide (NAD(+)) administration significantly blocked RPE cell death induced by 300 μM H2O2. Further investigation showed that H2O2 resulted in increased intracellular ROS level, activation of PARP-1 and subsequently necrotic death of RPE cells. Exogenous NAD(+) administration significantly decreased intracellular and intranuclear ROS levels in H2O2-treated RPE cells. In addition, NAD(+) administration to H2O2-treated RPE cells inhibited the activation of PARP-1 and protected the RPE cells against necrotic death. Moreover, exogenous NAD(+) administration up-regulated autophagy in the H2O2-treated RPE cells. Inhibition of autophagy by LY294002 blocked the decrease of intracellular and intranuclear ROS level. Besides, inhibition of autophagy by LY294002 abolished the protection of exogenous NAD(+) against H2O2-induced cell necrotic death. Taken together, our findings indicate that that exogenous NAD(+) administration suppresses H2O2-induced oxidative stress and protects RPE cells against PARP-1 mediated necrotic death through the up-regulation of autophagy. The results suggest that exogenous NAD(+) administration might be potential value for the treatment of AMD.

    The most appropriate time for administration was studied based on examination of the total number of leukocytes, differential white blood count, and the number of platelets in 30 cases in which 200 μg Romurtide (Nopia) was injected subcutaneously on the day of radiotherapy, 5 times a week, for 2 weeks, totally 10 times because leukopenia was caused during treatment with radiotherapy. It was recognized that the number of leukocytes, mainly neutrophils, increased from 1 week after starting administration of Romurtide to after the completion of administration (2 weeks after administration), except 1 week after completion of administration. The increasing effect in the number of platelets was not recognized, and it had decreased from at the completion of administration to 1 week after the completion of administration of Romurtide. The rate of completion of radiotherapy was 100% without any serious adverse events, but there were 4 cases in which fever was observed. Therefore, it is not very favorable to administer Romurtide immediately after radiation, taking account of the treatment period of radiotherapy. It is also considered that it would be necessary to start radiation after sufficient recovery of the number of leukocytes or increase in their number by using G-CSF preparation in cases in which the leukocyte count has fallen since starting radiation due to the influence of the preceding chemotherapy.

    In the reward mesocorticolimbic circuits, the glutamatergic and endocannabinoid systems are implicated in neurobiological mechanisms underlying cocaine addiction. However, the involvement of both systems in the hippocampus, a critical region to process relational information relevant for encoding drug-associated memories, in cocaine-related behaviors remains unknown. In the present work, we studied whether the hippocampal gene/protein expression of relevant glutamate signaling components, including glutamate-synthesizing enzymes and metabotropic and ionotropic receptors, and the hippocampal gene/protein expression of cannabinoid type 1 (CB1) receptor and endocannabinoid metabolic enzymes were altered following acute and/or repeated cocaine administration resulting in conditioned locomotion and locomotor sensitization. Results showed that acute cocaine administration induced an overall down-regulation of glutamate-related gene expression and, specifically, a low phosphorylation level of GluA1. In contrast, locomotor sensitization to cocaine produced an up-regulation of several glutamate receptor-related genes and, specifically, an increased protein expression of the GluN1 receptor subunit. Regarding the endocannabinoid system, acute and repeated cocaine administration were associated with an increased gene/protein expression of CB1 receptors and a decreased gene/protein expression of the endocannabinoid-synthesis enzymes N-acyl phosphatidylethanolamine D (NAPE-PLD) and diacylglycerol lipase alpha (DAGLα). These changes resulted in an overall decrease in endocannabinoid synthesis/degradation ratios, especially NAPE-PLD/fatty acid amide hydrolase and DAGLα/monoacylglycerol lipase, suggesting a reduced endocannabinoid production associated with a compensatory up-regulation of CB1 receptor. Overall, these findings suggest that repeated cocaine administration resulting in locomotor sensitization induces a down-regulation of the endocannabinoid signaling that could

    Self-administration of addictive drugs is a widely used tool for studying behavioral, neurobiological, and genetic factors in addiction. However, how locomotor activity is affected during self-administration of addictive drugs has not been extensively studied. In our present study, we tested the locomotor activity levels during acquisition, extinction and reinstatement of morphine self-administration in rats. We found that compared with saline self-administration (SA), rats that trained with morphine SA had higher locomotor activity. Rats that successfully acquired SA also showed higher locomotor activity than rats that failed in acquiring SA. Moreover, locomotor activity was correlated with the number of drug infusions but not with the number of inactive pokes. We also tested the locomotor activity in the extinction and the morphine-primed reinstatement session. Interestingly, we found that in the first extinction session, although the number of active pokes did not change, the locomotor activity was significantly lower than in the last acquisition session, and this decrease can be maintained for at least six days. Finally, morphine priming enhanced the locomotor activity during the reinstatement test, regardless of if the active pokes were significantly increased or not. Our results clearly suggest that locomotor activity, which may reflect the pharmacological effects of morphine, is different from drug seeking behavior and is a distinctive index in drug self-administration.

Moreover, locomotor activity was correlated with the number of drug infusions but not with the number of inactive pokes. We also tested the locomotor activity in the extinction and the morphine-primed reinstatement session. Interestingly, we found that in the first extinction session, although the number of active pokes did not change, the locomotor activity was significantly lower than in the last acquisition session, and this decrease can be maintained for at least six days. Finally, morphine priming enhanced the locomotor activity during the reinstatement test, regardless of if the active pokes were significantly increased or not. Our results clearly suggest that locomotor activity, which may reflect the pharmacological effects of morphine, is different from drug seeking behavior and is a distinctive index in drug self-administration.

    Nasal administration of thallium-201 ( 201 Tl) has previously been shown to be useful for the assessment of olfactory nerve connectivity in vivo. We assessed the biological effects of nasal 201 Tl administration in mice to determine its safety before conducting clinical trials on humans. 201 Tl uptake was evaluated in normal mice (n=5) in vivo by using a high-resolution gamma camera and radiography 15 min, 1, 2 and 9 d after administration of 201 TlCl to the right side of the nasal cavity (10 μl 201 TlCl per nostril, 74 MBq/ml). Murine olfactory epithelial thickness (n=5) was measured 9 d following nasal administration of 201 TlCl. We assessed the odor detection ability of normal mice (n=8) following nasal administration of 201 TlCl to both sides of the nasal cavity, by observing cycloheximide solution avoidance behavior. We subsequently administrated 201 TlCl (n=4) or saline (n=4) to both nostrils to assess the odor detection ability of mice following bilateral olfactory nerve transection. 201 Tl uptake by the nasal cavity decreased immediately following nasal administration of 201 Tl in normal mice. Nasal administration of 201 Tl did not affect the olfactory epithelial thickness or the odor detection ability of normal mice. Recovery of odor detection ability following olfactory nerve transection was not significantly different between mice nasally administered with 201 Tl, and mice administered with saline. Thus, nasal administration of 201 Tl for the diagnosis of traumatic olfactory impairment did not produce harmful biological effects in vivo. (author)

    Rationale Combining alcohol and caffeine is associated with increased alcohol consumption, but no prospective experimental studies have examined whether added caffeine increases alcohol consumption. Objectives This study examined how caffeine alters alcohol self-administration and subjective reinforcing effects in healthy adults. Methods Thirty-one participants completed six double-blind alcohol self-administration sessions: three sessions with alcohol only (e.g., Beverage A) and three sessions with alcohol and caffeine (e.g., Beverage B). Participants chose which beverage to consume on a subsequent session (e.g., Beverage A or B). Effects of caffeine on overall beverage choice, number of self-administered drinks, subjective ratings (e.g., Biphasic Alcohol Effects Scale), and psychomotor performance were examined. Results A majority of participants (65%) chose to drink the alcohol beverage containing caffeine on their final self-administration session. Caffeine did not increase the number of self-administered drinks. Caffeine significantly increased stimulant effects, decreased sedative effects, and attenuated decreases in psychomotor performance attributable to alcohol. Relative to nonchoosers, caffeine choosers reported overall lower stimulant ratings, and reported greater drinking behavior prior to the study. Conclusions Although caffeine did not increase the number of self-administered drinks, most participants chose the alcohol beverage containing caffeine. Given the differences in subjective ratings and pre-existing differences in self-reported alcohol consumption for caffeine choosers and nonchoosers, these data suggest decreased stimulant effects of alcohol and heavier self-reported drinking may predict subsequent choice of combined caffeine and alcohol beverages. These predictors may identify individuals who would benefit from efforts to reduce risk behaviors associated with combining alcohol and caffeine. PMID:28108773

    Full Text Available The objective of this study was to determine the physiological effects of detomidine on Pateri goats. A total of six female Pateri goats were randomly treated with three different dose rates of Detomidine at 40 μg, 50 μg and 60 μg/kg body weights. The effects of Detomidine on respiratory and heart rate, rectal temperature and serum glucose level were investigated. Following detomidine intravenous administration in goats, it produced dose dependent effect on physiological parameters. Respiratory and heart rate decreased after intravenous administration in all goats. The heart rate decreased at 5 min with all dose rates and returned to the base line at 60 min. This change in heart rate was dose dependent and there was no significant (P>0.05 change observed with 40 μg and 50 μg/kg of Detomidine. However, there was significant difference (P<0.05 at 75 min between the 40 μg and 60 μg/kg of Detomidine in all goats. However, significant (P<0.01 increase in serum glucose level occurred with all dose rates at 30 min compared with control groups. It is concluded that Detomidine has produced no adverse effect on physiological parameters.

    Previous studies listed body surface area (BSA), lean body mass (LBM), and age as modifying factors on the TSH concentrations after administration of recombinant human thyrotropin (rhTSH). The purpose of this study was to identify the main modifying factors on serum TSH levels and to compare the stimulation via single rhTSH injection after a short thyroid hormone withdrawal (THW) with that of the standard stimulating protocol. 106 patients with differentiated thyroid cancer (DTC) undergoing radioiodine therapy (RIT) after rhTSH administration were obtained through chart review. Two groups were evaluated: Group I was treated with a single rhTSH administration after two weeks of T3 therapy followed by one week of THW. Group II was stimulated according to the international standard protocol via rhTSH injections for two consecutive days. Serum TSH concentrations were documented prior to rhTSH administration (day 1 TSH), one day after (day 3 TSH) and 3-6 days after (mean 4.2 days, day 6 TSH) the last rhTSH injection. The following data was collected: age, gender, weight, height, BMI, LBM, BSA, residual thyroid tissue, CRP, creatinine, GFR, liver enzymes, alkaline phosphatase, cholesterol, and triglycerides. Group I: Age combined with anthropometric factors like BMI (TSH increase and day 6 TSH), BSA (TSH decrease), and gender (day 6 TSH) are the main modifying factors on serum TSH concentrations after rhTSH administration. Group II: Age and lean body mass (LBM) showed a significant impact on day 3 TSH, TSH increase (day 3-day 1), and TSH decrease (day 6-day 3). Day 6 TSH was found to be influenced by GFR (group II). Age and anthropometric parameters have significant independent influence on TSH concentrations after rhTSH injection in both groups. Anthropometric parameters (BSA, LBM) and demographic parameters (female gender) show strong influence on TSH concentrations. Further research should be conducted to examine the influence of body compartments on TSH levels

    Intestinal barrier dysfunction is not only the consequence of liver cirrhosis, but also an active participant in the development of liver cirrhosis. Previous studies showed that external administration of insulin-like growth factor 1 (IGF-1) improved intestinal barrier function in liver cirrhosis. However, the mechanism of IGF-1 on intestinal barrier in liver cirrhosis is not fully elucidated. The present study aims to investigate the mechanisms of IGF-1 improving intestinal barrier function via regulating tight junctions in intestines. We used carbon tetrachloride induced liver cirrhotic rats to investigate the effect of IGF-1 on intestinal claudin-1 and occludin expressions, serum alanine transaminase (ALT) and aspartate transaminase (AST) levels, severity of liver fibrosis, portal pressures, enterocytic apoptosis and lipopolysaccharides (LPS) levels in portal vein. The changes of IGF-1 in serum during the development of rat liver cirrhosis were also evaluated. Additionally, we assessed the effect of IGF-1 on claudin-1 and occludin expressions, changes of transepithelial electrical resistance (TEER) and apoptosis in Caco-2 cells to confirm in vivo findings. Serum IGF-1 levels were decreased in the development of rat liver cirrhosis, and external administration of IGF-1 restored serum IGF-1 levels. External administration of IGF-1 reduced serum ALT and AST levels, severity of liver fibrosis, LPS levels in portal vein, enterocytic apoptosis and portal pressure in cirrhotic rats. External administration of IGF-1 increased the expressions of claudin-1 and occludin in enterocytes, and attenuated tight junction dysfunction in intestines of cirrhotic rats. LPS decreased TEER in Caco-2 cell monolayer. LPS also decreased claudin-1 and occludin expressions and increased apoptosis in Caco-2 cells. Furthermore, IGF-1 attenuated the effect of LPS on TEER, claudin-1 expression, occludin expression and apoptosis in Caco-2 cells. Tight junction dysfunction develops during the

    Several studies have provided indirect evidence that neuropeptide Y (NPY) may play a role in the regulation of ethanol consumption. However, the direct effects of central NPY administration on ethanol drinking are unclear. This study examined the effects of NPY on ethanol, sucrose, and food consumption as well as its concomitant effects on the cortical EEG. Wistar rats were implanted with cortical recording electrodes and a cannula in the third ventricle after using a sucrose substitution procedure to establish ethanol self-administration. NPY (0-15 microg/3.0 microl) was infused into the third ventricle prior to drinking sessions, when 10% ethanol (10E), 2% sucrose (2S), 0.5% sucrose (0.5S), or food were available. Behavior and cortical EEG were monitored during the sessions. NPY had no effect on the intake of 10E, 2S, or 0.5S, but NPY (15 microg/3.0 microl) significantly increased food intake. Under baseline drinking conditions, EEG power in the 6-8 Hz range was significantly greater when 2S was consumed compared to 10E. NPY decreased power in the 8-16 Hz range, decreased peak frequency in the 6-8 Hz range, and increased peak frequency in the 32-50 Hz range when 10E or 2S was available. These data suggest that NPY administration into the third ventricle preferentially regulates feeding compared to ethanol or sucrose drinking. In addition, since NPY significantly altered the cortical EEG in the absence of effects on ethanol and sucrose consumption, these data may indicate that NPY's cortical EEG effects are more related to its sedative or anxiolytic properties, rather than any effect on consumption.

    Full Text Available In this study, higher education administrators, administrative behaviors; as educator, leader and manager, emotional competency; as self awareness and self management and social competency; as social awareness and social skills were compared according to two different cultures. The data was collected by inventories from 165 educators, and head of the departments Istanbul, and Helsinki Universities in 2008-2009 educational year. Elkins' administrative behaviors of higher education administrators inventory and Goleman's emotional and social competence inventory were conducted to test the differences. The manager behaviors of Istanbul University administrators are significantly higher than University of Helsinki administrators. The emotional competences of University of Helsinki administrators are significantly higher than the administrators of Istanbul University in the dimensions of self-awareness, self management, emotional selfcontrol, achievement orientation and positive outlook. The social competencies of University of Helsinki administrators are significantly higher than the administrators of Istanbul University in the dimensions of social awareness, empathy, and conflict management. On the other hand, the social competencies of Istanbul University administrators are significantly higher than the administrators of University of Helsinki in the dimensions of organizational awareness, coach and mentor, influence and teamwork. There is a significant positive relationship between the leadership behaviors and emotional and social competencies administrators in both Istanbul University and University of Helsinki. Significant differences are found between faculties and administrators about the administrative behaviors and emotional and social competences of administrators both at İstanbul University and University of Helsinki.

    Administration of corazole into animals led to a decrease in content of NAD and gamma-aminobutyric acid (GABA) in brain. Under these conditions, binding of 14 C-GABA was increased and its liberation was inhibited in the synaptosomes of the brain cortex. Additional administration of incotinamide, accompanied by considerable increase in content of NAD and GABA, caused a decrease in accumulation of exogenous GABA in the synaptosomes and removed the effects produced by the convulsant agent. Kinetics of 14 C-GABA binding in the presence of NAD demonstrated that the more effective inhibition of the binding occurred in the animals treated with the convulsant drug. NAD appears to affect the GABA-ergic transmission at the postsynaptic level

    Chemotherapy involving L-asparaginase was performed on a 9-year-old female child with malignant lymphoma, and a 3-year-old male child and a 14-year-old female child with acute lymphatic leukemia, and the course of L-asparaginase-induced fatty liver was followed up primarily by CT findings. In all 3 cases, L-asparaginase administration caused a marked fatty liver characterized by a diffuse cold area of the liver and a decrease in the value of the liver (liver/spleen<1) on CT. Hypoproteinemia, hypofibrinogenemia and elevations of GOT and GPT were simultaneously observed, but marked anemia, pancreatitis, decreased glucose tolerance and central nervous disorder did not occur. Recovery of fatty liver was slower in CT findings than in blood biochemistry, taking about 4 weeks.

    There was a dramatic increase in the volume of manuscripts submitted to The Journal of Bone & Joint Surgery (JBJS) between 2009 and 2012. This resulted in increased journal administrative costs. To offset this financial burden, in May 2013, JBJS started charging authors an administrative processing fee at the time of submission. The purpose of this study was to assess the impact of the administrative fee on the volume and characteristics of manuscripts submitted to JBJS. Our analysis included 866 manuscripts submitted to JBJS between November 2012 and November 2013. We compared manuscripts submitted 6 months prior to fee implementation and prior to the announcement (denoted as the baseline group), in the several months prior to fee implementation but after the fee implementation announcement (denoted as the fee announcement group), and in the 6 months after fee implementation (denoted as the fee implementation group). Manuscripts were reviewed for institutional and author demographic characteristics, as well as for general study characteristics. In the first full calendar year (2014) after the implementation of the fee, the annual volume of submissions to JBJS declined by 33.5% compared with the annual submission volume in 2010 to 2012. In a comparative analysis, the geographical region of origin (p = 0.003), level of evidence (p Reporting of funding information improved significantly between the baseline and fee implementation groups; in the post-fee implementation period, studies were more likely to have declared no external funding source (p = 0.001). The administrative processing fee at JBJS has been associated with a decrease in submission volume, but, overall, there has not been a change in the characteristics of studies submitted. However, decreased overall volume implies a decrease in the absolute number of high-level studies submitted to the journal. Administrative processing fees at high-volume journals may be a financially viable way to offset high

    2017-06-01

    Full Text Available The article, analyzing the administrative litigation in the comparative law, groups the existing types of administrative litigation into four major systems, namely: a States with administrative jurisdictions who have the State Council on top, administrative body with consultative and judicial role (the French system; b States with administrative jurisdictions completely separated from the active and consultative administrations (the German system; c States with administrative jurisdictions included in the judicial system; d States with no administrative jurisdiction (English system. The administrative contentious systems analyzed have developed in line with historical evolution and legal traditions and have been continually adapted to the realities existing in each state. The manner in which the administrative contentious is regulated in a State reflects the degree of democratization of that country, the extent to which the citizen enjoys legal safeguards to defend himself against abuses by public authorities. The scientific novelty of this article is to capture the latest trends in the evolution of the administrative contentious systems analyzed. This study aims to provide an easy working tool for reforming administrative litigation on comparative law in states with young democracy. In the research we used the comparative method, the historical and the logical method.

    Full Text Available Administrative decision-making by official who conducting the administrative procedure may have a number of advantages over the decisionmaking by the senior official which manages by the administrative authority. However, to make that such a novelty have positive effects, it is necessary, next to the amendments to the Law on Administrative Procedure, to create a number of legal and factual assumptions, on whom are based highly politicized and professionalised administrative systems today. In order to create the legal conditions for the introduction of innovations in administrative proceedings in the Republic of Serbia, it is necessary to appropriately modify, firstly certain provisions of the Law on Public Administration, as the basic systemic regulation in this area, and then the Law on Civil Servants, as the basic status regulation, so the civil servant career become less dependent on the will of officials who manage by the administrative authorities. Also, it is essential to solve a number of other issues on a proper legal way, such as way of harmonizing administrative practice within the same administrative authority, a way of solving the appeals in the case of first instance decisions made by independent administrative authority, different rules for conflict of interest with the state officers who may be authorized officials in administrative proceedings, etc.

    2016-07-01

    Full Text Available The aim of this article is to conduct an analysis of the constitutionalization of Administrative Law, which results from changes in the rule of law and, under a theoretical standpoint, from the paradigm shift of legal exegesis followed by the advent of neo-constitutionalism, which poses the Constitution as the parameter for the interpretation of the other legal branches. Within this context, considering that the concept of administrative discretion goes through interpretation changes and that administrative activity is performed within the boundaries of discretion, this power/duty must always be used with substantial regulatory criteria in order to get the maximum effectiveness of the constitutional rules, thus being subjected to review. In this sense, it is demonstrated that a public official cannot in any way deviate from the realization of the fundamental rights guaranteed by the Constitution, hence stating the reviewability of the administrative discretion.

    Full Text Available Cadmium is a wide-spread heavy metal that causes a wide range of health problems in animals and humans. Many reports showed the biosorption of heavy metals by bacteria. The objectives of this study were to evaluate the potency of probiotics bacteria of Lactobacillus plantarum and Bacillus coagulans against cadmium adsorption in rats. Twenty four male adult Wistar rats were randomly divided into six groups. Cadmium treated groups received 1 ml of 100 µg/ml CdCl2 and probiotics groups were administrated 1 ml of (109 CFU/ml of probiotics during 24 days by special gavage needle once daily. Levels of cadmium were determined by using graphite furnace atomic absorption spectrometry. Probiotics B. coagulans and L. plantarum caused 29.8% and 19.3% increasing in removal of cadmium through defecation and decreased 10.9 and 21.5 % of cadmium accumulation in kidney of Wistar rats. The results showed that oral administration of both probiotics offered a significant protective effect against cadmium adsorption in rats.

    Cosgrove, Kelly P; Hunter, Robb G; Carroll, Marilyn E

    2002-10-01

    This experiment examines the effect of access to a running-wheel on intravenous cocaine self-administration in male and female rats. Rats maintained at 85% of their free-feeding body weight were first exposed to the running-wheel alone during the 6-h sessions until behavior stabilized for 14 days. Intravenous cannulae were then implanted, and the rats were trained to self-administer a low dose of cocaine (0.2 mg/kg) under a fixed-ratio (FR 1) schedule during the 6-h sessions, while the wheel remained inactive and cocaine self-administration stabilized (cocaine-only condition). Next, the wheel access and cocaine self-administration were concurrently available followed by a period of cocaine-only. Behavior was allowed to stabilize for 10 days at each phase. During wheel access, cocaine infusions decreased by 21.9% in males and 70.6% in females compared to the cocaine-only condition; the effect was statistically significant in females. Infusions increased to baseline levels when wheel access was terminated. When cocaine infusions were concurrently available, wheel revolutions were reduced by 63.7% and 61.5% in males and females, respectively, compared to the wheel-only condition. This result did not differ due to sex, but it was statistically significant when data from males and females were combined. These results indicate that wheel-running activity had a greater suppressant effect on cocaine self-administration in females than in males, and in females, wheel-running and cocaine self-administration are substitutable as reinforcers.

    Full Text Available We investigated the effects of rikkunshito (RKT, a ghrelin signal enhancer, on the decrease in food intake after exposure to novelty stress in mice. RKT administration (500 mg/kg, per os improved the decrease in 6 h cumulative food intake. In control mice, the plasma acylated ghrelin levels significantly increased by 24 h fasting. In contrast, the acylated ghrelin levels did not increase by fasting in mice exposed to the novelty stress. RKT administration to the novelty stress mice showed a significant increase in the acylated ghrelin levels compared with that in the distilled-water-treated control mice. Food intake after administering serotonin 2B (5-HT2B receptor antagonists was evaluated to clarify the role of 5-HT2B receptor activation in the decrease in feeding behavior after novelty stress. SB215505 and SB204741, 5-HT2B receptor antagonists, significantly improved the decrease in food intake after exposure to novelty stress. A component of RKT, isoliquiritigenin, prevented the decrease in 6 h cumulative food intake. Isoliquiritigenin showed 5-HT2B receptor antagonistic activity in vitro. In conclusion, the results suggested that RKT improves the decrease in food intake after novelty stress probably via 5-HT2B receptor antagonism of isoliquiritigenin contained in RKT.

  11. [Health management as part of leadership in public administration].

    Matyssek, A K

    2012-02-01

    Leadership includes two tasks within public administration: leading employees by creating healthy working conditions and being led by others. The basis of leading others in a healthy way means dealing with oneself in a healthy manner; this includes typical healthy behavior (i.e., physical activity, improved nutrition, not smoking), which allows for recovery by a good work-life balance and a sensitive dealing with one's own limits. Given these conditions of healthy self care, managers are able to act as role models and lead their employees in a healthy manner. Leading in a healthy manner means showing appreciation, being interested in the employees ("caring"), integrating them in decision-making, allowing transparency, improving the working atmosphere, and finally reducing stress and increasing resources. The latter includes social support, which decreases the danger of employees burning out. The article presents the concept of a 2-day training that is designed for managers in order to raise their awareness for duties related to health management in public administration.

    Full Text Available Background. Diarylheptanoids administration increases the efficacy of cyclophosphamide and reduces the activity of lipid peroxidation processes, allowing to decrease the dose of a cytostatic agent and reduce its side effects. The purpose of the study was to determine the protective properties of diarylheptanoid oregonin against the toxic effects of cyclophosphamide on the leukocyte count and the concentration of free amino acids in the blood plasma and spleen tissue. Material and methods. Male rats treated with cyclophosphamide (160 mg/kg body weight and oregonin (5 mg/kg body weight were used in the study. The determination of free amino acids was performed by the reversed-phase HPLC. Results. It has been established that the administration of a course of oregonin together with cyclophosphamide increases the content of amino acids and their derivatives in blood plasma as well as the availability of proteinogenic amino acids in spleen cells. Conclusion. Administration of a course of oregonin together with cyclophosphamide has a protective effect against the amino acid imbalance in the blood plasma and spleen tissue.

    We compared the effects of three micro-(DAMGO, DALDA, TNPO) and three delta-(DPDPE, DELT, SNC-80) opioid agonists on arterial blood gas after IV administration in awake sheep. None of the mu agonists altered pO2, pCO2 or pH. All three mu agonists decreased pO2 increased pCO2 and decreased pO2, and this effect was not sensitive to naloxone or TIPPpsi, a delta-antagonist, suggesting that it is not mediated by beta-opioid receptors. When administered to pregnant animals, there were significant changes in fetal pCO2 and pH. It may be possible to develop delta-selective opioid agonists which do not produce respiratory depression.

    Co-morbidity information derived from administrative data needs to be validated to allow its regular use. We assessed evolution in the accuracy of coding for Charlson and Elixhauser co-morbidities at three time points over a 5-year period, following the introduction of the International Classification of Diseases, 10th Revision (ICD-10), coding of hospital discharges. Cross-sectional time trend evaluation study of coding accuracy using hospital chart data of 3'499 randomly selected patients who were discharged in 1999, 2001 and 2003, from two teaching and one non-teaching hospital in Switzerland. We measured sensitivity, positive predictive and Kappa values for agreement between administrative data coded with ICD-10 and chart data as the 'reference standard' for recording 36 co-morbidities. For the 17 the Charlson co-morbidities, the sensitivity - median (min-max) - was 36.5% (17.4-64.1) in 1999, 42.5% (22.2-64.6) in 2001 and 42.8% (8.4-75.6) in 2003. For the 29 Elixhauser co-morbidities, the sensitivity was 34.2% (1.9-64.1) in 1999, 38.6% (10.5-66.5) in 2001 and 41.6% (5.1-76.5) in 2003. Between 1999 and 2003, sensitivity estimates increased for 30 co-morbidities and decreased for 6 co-morbidities. The increase in sensitivities was statistically significant for six conditions and the decrease significant for one. Kappa values were increased for 29 co-morbidities and decreased for seven. Accuracy of administrative data in recording clinical conditions improved slightly between 1999 and 2003. These findings are of relevance to all jurisdictions introducing new coding systems, because they demonstrate a phenomenon of improved administrative data accuracy that may relate to a coding 'learning curve' with the new coding system.

    Research on social class and generosity suggests that higher-income individuals are less generous than poorer individuals. We propose that this pattern emerges only under conditions of high economic inequality, contexts that can foster a sense of entitlement among higher-income individuals that, in turn, reduces their generosity. Analyzing results of a unique nationally representative survey that included a real-stakes giving opportunity (n = 1,498), we found that in the most unequal US states, higher-income respondents were less generous than lower-income respondents. In the least unequal states, however, higher-income individuals were more generous. To better establish causality, we next conducted an experiment (n = 704) in which apparent levels of economic inequality in participants’ home states were portrayed as either relatively high or low. Participants were then presented with a giving opportunity. Higher-income participants were less generous than lower-income participants when inequality was portrayed as relatively high, but there was no association between income and generosity when inequality was portrayed as relatively low. This research finds that the tendency for higher-income individuals to be less generous pertains only when inequality is high, challenging the view that higher-income individuals are necessarily more selfish, and suggesting a previously undocumented way in which inequitable resource distributions undermine collective welfare.

    Background Fiscal constraints faced by Medicare are leading to policies designed to reduce expenditures. Evidence of the effect of reduced reimbursement on the mortality of Medicare patients discharged from all major hospital service lines is limited. Methods We modeled risk-adjusted 30-day mortality of patients discharged from 21 hospital service lines as a function of service line profitability, service line time trends, and hospital service line and year-fixed effects. We simulated the effect of alternative revenue-neutral reimbursement policies on mortality. Our sample included all Medicare discharges from PPS-eligible hospitals (1997, 2001, and 2005). Results The results reveal a statistically significant inverse relationship between changes in profitability and mortality. A $0.19 average reduction in profit per $1.00 of costs led to a 0.010–0.020 percentage-point increase in mortality rates (p payment generosity than in service lines that remain profitable. Policy simulations that target service line inequities in payment generosity result in lower mortality rates, roughly 700–13,000 fewer deaths nationally. Conclusions The policy simulations raise questions about the trade-offs implicit in universal reductions in reimbursement. The effect of reduced payment generosity on mortality could be mitigated by targeting highly profitable services only for lower reimbursement. PMID:23346946

    Rats were injected with (/sup 125/I)L-thyroxine (T/sub 4/) ip 16 h before the experiment and samples of blood were frequently taken from polyethylene tubing inserted into the femoral artery in anaesthetized and heparin-injected animals. In each sample of plasma T/sub 4/ counts per ml were estimated with the acid of paper chromatography. Rapid decrease of circulating T/sub 4/ level was found at 20 min after iv injection of thiocyanate, iodide, fluoroborate, theophylline and salicylate and a dose-response relationship was established between such a decrease and the administered dose of salicylate (5-160 mg/400 g b.w.). A similar decrease was observed at 60 min after ip injection of some general anaesthetics or tranquilizers. An increase of T/sub 4/ fractional disposal rate was found between 120 and 480 min after the administration of some of the anaesthetics and this effect was abolished by the administration of thiocyanate. It was concluded that there are two different effects of drugs on the circulating T/sub 4/ level: 1. the immediate effect resulting apparently from a decreased plasma protein binding. 2. the prolonged effect which presumably results from the increased turnover of T/sub 4/ by peripheral tissues, the metabolic basis of which remains unexplained.

    Full Text Available AIM: To compare the pharmacokinetic differences of the 2% diacerein eye drops between conjunctival sac multiple administration and single administration in the cornea, and to provide the experimental basis for clinicians to use the conjunctival sac multiple administration.METHODS: Male Kunming mice were randomly divided into the multiple administration group and the single administration group. The multiple administration group were given diacerein eye drop every 2min(3 times in total. The concentrations of the metabolites of diacerein in the cornea were measured by high performance liquid chromatography after given eye drop 5, 15, 30, 60, 120, and 180min. The pharmacokinetic parameters were calculated by pharmacokinetic software(DAS2.1.1. RESULTS: The metabolites of diacerein, rhein, was detected in the cornea at each time point. The concentration of the metabolite of diacerein in the cornea was 318.678±40.88, 210.02±25.66, 188.83±31.74, 112.24±11.70, 90.28±22.01 and 57.67±13.71μg/g after given eye drop 5, 15, 30, 60, 120, and 180min in the multiple administration group.

    Full Text Available ABSTRACT Relapse is highly prevalent after detoxification and depression. Due to the advantages of venlafaxine compared with other antidepressants, it is expected that venlafaxine administration may reduce relapse after detoxification and depression. This study aimed to evaluate the effects of venlafaxine on depression-induced relapse to morphine dependence after methadone detoxification. Eighty Sprague-Dawley rats were habituated and conditioned with morphine (10 mg/kg, S.C., for 4 days. After that, primary forced swimming and conditioned place preference (CPP were tested. They were followed by methadone (70 mg/kg/day, P.O., for 7 days administration, extinguishing, forced swimming stress (FSS and administration of venlafaxine (80 mg/kg/day, I.P., for 7 days. Finally same tests were performed. Administration of venlafaxine resulted in a decrement in final preference scores associated with a prime morphine injection (PMI compared to the primary scores in methadone treated (MTD+ animals. In a swimming test, venlafaxine increased the amount of final floating and decreased final activity scores compared with the primary scores after administration of methadone. Venlafaxine reduced locomotor activity in MTD+ animals in the final test with PMI. There was a positive correlation between the final activity and preference scores after PMI. In conclusion, venlafaxine improved anxiety and depression-induced relapse on methadone detoxified rats.

Materials and Methods: Rats were equally divided into 7 groups; control (corn oil, DZN (15 mg/kg, crocin (each group received 12.5, 25 or 50 mg/kg crocin plus DZN, vitamin E (200 IU/kg plus DZN and crocin (50 mg/kg treated groups.  Rats were given DZN via gavage once a day for 4 weeks. Vitamin E (three times per week and crocin (once a day were intraperitoneally injected to rats for 4 weeks. Plasma cholinesterase activity (Elman method, malondealdehyde (MDA levels in the aortic tissue (Thiobarbituric acid reactive substances or TBARS method; SBP and HR (tail cuff method were evaluated at the end of 4th week. Results: A significant decrease in cholinesterase activity was observed in DZN group (P< 0.001. Crocin did not show any effects on cholinesterase activity. DZN increased MDA levels in aortic tissue (P< 0.001 in comparison with control group. Crocin and vitamin E plus DZN decreased MDA elevation induced by DZN in aortic tissue. DZN significantly reduced SBP (P< 0.01 and increased HR (P< 0.001 in comparison with control. Concurrent administration of crocin and DZN, improved the reduction of SBP and the elevation of HR induced by DZN in rat. Crocin alone did not have any effect on SBP and HR. Conclusion: This study showed that concurrent administration of crocin and DZN could restore the effects of subchronic DZN administration on SBP and HR in rats.

    Chemotherapy involving L-asparaginase was performed on a 9-year-old female child with malignant lymphoma, and a 3-year-old male child and a 14-year-old female child with acute lymphatic leukemia, and the course of L-asparaginase-induced fatty liver was followed up primarily by CT findings. In all 3 cases, L-asparaginase administration caused a marked fatty liver characterized by a diffuse cold area of the liver and a decrease in the value of the liver (liver/spleen<1) on CT. Hypoproteinemia, hypofibrinogenemia and elevations of GOT and GPT were simultaneously observed, but marked anemia, pancreatitis, decreased glucose tolerance and central nervous disorder did not occur. Recovery of fatty liver was slower in CT findings than in blood biochemistry, taking about 4 weeks. (Chiba, N.)

    2011-08-01

    Full Text Available The general objective of the paper is based on an extremely present theme of real interest. Using the content analysis, through a descriptive documentary research, the present study aims at identifying the dimensions of the general principles of good administration, in the context of changes at European an implicitly at national level. To this purpose, an analisys of the specific objectives will be made: the concept of good administration, the national dimensions of the right to be heard, the right to access personal files as well as the motivation of administrative acts and the general principles regulated by the European Code of Good Administration will be underlined, in the context of institutional change determined by the Lisbon Treaty. Good administration defines the way in which institutions function, this being possible by ensuring the right to access information, a more efficient protection of fundamental rights as well as the right to defense, publication of acts and their motivation. Good administration is strongly connected to good government, the relation being in our opinion, from part to whole. The final purpose of good government and implicitly of good administration aims at accomplishing the general interest. The two concepts need a higher degree of transparency and responsibility in the public process. If governing represents the modality of exerting power, good government entails the imperative of the consensus of those governed regarding the objectives and methods of government, the responsibility of those governing, the efficiency of governing and the citizens’ right to be informed regarding the use and the distribution of the financial resources in the governing process. This new concept takes into account the implication of the citizens in the decision - making process, allowing a more efficient use of material, human, and financial resources. We assert thus that by applying the general principles of good administration

    Fenproporex is an amphetamine-based anorectic and it is rapidly converted in vivo into amphetamine. It elevates the levels of extracellular dopamine in the brain. Acetylcholinesterase is a regulatory enzyme which is involved in cholinergic synapses and may indirectly modulate the release of dopamine. Thus, we investigated whether the effects of chronic administration of fenproporex in adult rats alters acquisition and retention of avoidance memory and acetylcholinesterase activity. Adult male Wistar rats received repeated (14 days) intraperitoneal injection of vehicle or fenproporex (6.25, 12.5 or 25 mg/kg i.p.). For behavioral assessment, animals were submitted to inhibitory avoidance (IA) tasks and continuous multiple trials step-down inhibitory avoidance (CMIA). Acetylcholinesterase activity was measured in the prefrontal cortex, hippocampus, hypothalamus and striatum. The administration of fenproporex (6.25, 12.5 and 25 mg/kg) did not induce impairment in short and long-term IA or CMIA retention memory in rats. In addition, longer periods of exposure to fenproporex administration decreased acetylcholinesterase activity in prefrontal cortex and striatum of rats, but no alteration was verified in the hippocampus and hypothalamus. In conclusion, the present study showed that chronic fenproporex administration decreased acetylcholinesterase activity in the rat brain. However, longer periods of exposure to fenproporex did not produce impairment in short and long-term IA or CMIA retention memory in rats.

However, the incidence of dextrose administration during cardiac arrest and the association of dextrose administration with survival and other outcomes are unknown. We used the Get With The Guidelines®-Resuscitation national registry to identify adult patients with an in-hospital cardiac arrest between the years 2000 and 2010. To assess the adjusted effects of dextrose administration on survival, we used multivariable regression models with adjustment for multiple patient, event, and hospital characteristics. We performed additional analyses to examine the effects of dextrose on neurological outcome and return of spontaneous circulation. Among the 100,029 patients included in our study, 4,189 (4.2%) received dextrose during cardiac arrest resuscitation. The rate of dextrose administration increased during the study period (odds ratio 1.11, 95% confidence interval (CI) 1.09-1.12 per year, P dextrose during resuscitation had lower rates of survival compared with patients who did not receive dextrose (relative risk 0.88, 95% CI 0.80-0.98, P = 0.02). Administration of dextrose was associated with worse neurological outcome (relative risk 0.88, 95% CI 0.79-0.99, P = 0.03) but an increased chance of return of spontaneous circulation (relative risk 1.07, 95% CI 1.04-1.10, P dextrose during resuscitation in patients with in-hospital cardiac arrest was found to be associated with a significantly decreased chance of survival and a decreased chance of good neurological outcome.

    Opioid abuse is a major problem around the world. Identifying environmental factors that contribute to opioid abuse and addiction is necessary for decreasing this epidemic. In rodents, environmental enrichment protects against the development of low dose stimulant self-administration, but studies examining the effect of enrichment and isolation (compared to standard housing) on the development of intravenous opioid self-administration have not been conducted. The present study investigated the role of environmental enrichment on self-administration of the short-acting μ-opioid remifentanil. Rats were raised in an enriched condition (Enr), standard condition (Std), or isolated condition (Iso) beginning at 21 days of age and were trained to lever press for 1 or 3 μg/kg/infusion remifentanil in young adulthood. Acquisition of self-administration and responding during increasing fixed ratio requirements were assessed, and a dose-response curve was generated. In all phases, Enr rats lever pressed significantly less than Std and Iso rats, with Enr rats pressing between 9 and 40% the amount of Iso rats. Enr rats did not acquire remifentanil self-administration when trained with 1 μg/kg/infusion, did not increase responding over increasing FR when trained at either dose, and their dose-response curves were flattened compared to Std and Iso rats. When expressed as economic demand curves, Enr rats displayed a decrease in both essential value (higher α) and reinforcer intensity (Q 0 ) compared to Std and Iso rats at the 1 μg/kg/infusion training dose. Environmental enrichment reduced remifentanil intake, suggesting that social and environmental novelty may protect against opioid abuse.

  2. Chronic lead exposure decreases the vascular reactivity of rat aortas: the role of hydrogen peroxide.

    Full Text Available We investigated whether exposure to small concentrations of lead alters blood pressure and vascular reactivity. Male Wistar rats were sorted randomly into the following two groups: control (Ct and treatment with 100 ppm of lead (Pb, which was added to drinking water, for 30 days. Systolic blood pressure (BP was measured weekly. Following treatment, aortic ring vascular reactivity was assessed. Tissue samples were properly stored for further biochemical investigation. The lead concentration in the blood reached approximately 8 μg/dL. Treatment increased blood pressure and decreased the contractile responses of the aortic rings to phenylephrine (1 nM-100 mM. Following N-nitro-L arginine methyl ester (L-NAME administration, contractile responses increased in both groups but did not differ significantly between them. Lead effects on Rmax were decreased compared to control subjects following superoxide dismutase (SOD administration. Catalase, diethyldithiocarbamic acid (DETCA, and apocynin increased the vasoconstrictor response induced by phenylephrine in the aortas of lead-treated rats but did not increase the vasoconstrictor response in the aortas of untreated rats. Tetraethylammonium (TEA potentiated the vasoconstrictor response induced by phenylephrine in aortic segments in both groups, but these effects were greater in lead-treated rats. The co-incubation of TEA and catalase abolished the vasodilatory effect noted in the lead group. The present study is the first to demonstrate that blood lead concentrations well below the values established by international legislation increased blood pressure and decreased phenylephrine-induced vascular reactivity. The latter effect was associated with oxidative stress, specifically oxidative stress induced via increases in hydrogen peroxide levels and the subsequent effects of hydrogen peroxide on potassium channels.

  3. Contemporary Education for Public Administration

    Directory of Open Access Journals (Sweden)

    Ivan Koprić

    2007-01-01

    Full Text Available The paper examines the development of contemporary administrative education, as a crucial criterion without which it is not possible to achieve professionalism in public administration. While the term professionalism has a variety of meanings, today it is largely deemed that specific educational preparation is a foundation without which other elements of professionalism in public administration cannot be achieved. The level of professionalism, competence, education and knowledge thus become critical variables of administration reforms in transitional countries. Afterwards, the author examines the trends in the development of contemporary administrative education, pointing particularly to the importance of establishing a coherent, vertically passable system, i.e. a system which encompasses all levels of education – from secondary school education to doctoral studies. In this matter, one of the most important features in the development of administrative studies is their diversification, with simultaneous strengthening of the general administrative profile. Thus, the general administrative profile becomes modified, updated and extended by new teaching disciplines. In the final section of the paper, the author addresses the performance of administrative education in Croatia, pointing to its underdevelopment. Indeed, the author suggests that there are no sustainable results of reforms without the training of staff for administration.

    2006-01-01

    Dextrose is commonly administered to postparturient dairy cows, which often have low plasma phosphorus concentration ([P]) as a result of anorexia and sudden onset of lactation. Intravenous (IV) dextrose administration causes hypophosphatemia in other species. Bolus administration of dextrose to postparturient dairy cows results in a transient decrease in plasma [P]. Six healthy postparturient dairy cows. Using a crossover design, cows were administered 500 mL of 50% dextrose solution IV or a sham treatment. Plasma concentrations of glucose ([glucose]), immunoreactive insulin ([IRI]), and phosphorus were monitored for 12 hours after each treatment. Urine [P], [glucose], and volume and salivary [P] were also determined. Plasma [glucose], [IRI], and [P] were stable during sham treatment. Plasma [P] decreased rapidly after dextrose administration, dropping by 35% in 1 hour and remaining below baseline for 90 minutes. Salivary [P], urine [P], and urine volume per hour remained stable after dextrose administration, but glucose was detected in urine for up to 6 hours. The amount of glucose excreted in urine in 12 hours (11.9+/-4.5 g) was less than 5% of the administered dose. Regression analysis revealed a stronger association between plasma [P] and [IRI] than between plasma [P] and [glucose], suggesting that hyperinsulinemia drove the hypophosphatemia. Results indicate that low plasma [P] should be expected in cows that have received IV dextrose within 1 hour before blood sampling. Caution is advised when administering dextrose solution to cows already at risk of hypophosphatemia.

    The present study was designed to investigate the effects of acute and chronic administration of MK-801 (0.6 mg/kg), a noncompetitive NMDA-receptor antagonist on extracellular glutamate (Glu) and ascorbic acid (AA) release in the prefrontal cortex (PFC) of freely moving mice using in vivo microdialysis with open-field behavior. In line with earlier studies, acute administration of MK-801 induced an increase of Glu in the PFC. We also observed single MK-801 treatment increased AA release in the PFC. In addition, our results indicated that the basal AA levels in the PFC after MK-801 administration for 7 consecutive days were significantly decreased, and basal Glu levels also had a decreased tendency. After chronic administration (0.6 mg/kg, 7 days), MK-801 (0.6 mg/kg) challenge significantly decreased dialysate levels of AA and Glu. Our study also found that both acute and chronic administration of MK-801 induced hyperactivity in mice, but the intensity of acute administration was more than that of chronic administration. Furthermore, in all acute treatment mice, individual changes in Glu dialysate concentrations and the numbers of locomotion were positively correlated. In conclusion, this study may provide new evidence that a single MK-801 administration induces increases of dialysate AA and Glu concentrations in the PFC of freely moving mice, which are opposite to those induced by repeated MK-801 administration, with an unknown mechanism. Our results suggested that redox-response might play an important role in the model of schizophrenic symptoms induced by MK-801.

    1992-01-01

    8102, a 1,2-dihydroxy-3,6-bismethylamino diacetic derivative, is a new chelating agent for decorporation of radionuclides. The effectiveness of intragastric administration of this drug at different doses (50-1000 mg/kg of body) and at different times before or after giving thorium-234 in rats was reported. The results show that for rats given intragastricly 1000 mg/kg of 8102, the excretion of thorium-234 in urine for first two days is 4.5 times more than that for control rats and accumulations of thorium-234 in liver, skeleton and kidney for these rats were 30%, 62% and 68% as those for control rats, respectively. The effectiveness was reduced with decrease in dosage of 8102. Administration of 8102 at 1 or 2 h before injection of thorium-234 can improve the effectiveness for decorporation of thorium-234: accumulation of thorium-234 in liver was markedly less than that for rats given 8102 immediately after injection of thorium-234. Delayed administration of 9102 resulted in reduction of the effectiveness. The practicality of oral administration of 8102 in clinic for decorporation of radionuclides was discussed

  15. Curcuma longa (curcumin) decreases in vivo cisplatin-induced ototoxicity through heme oxygenase-1 induction.

    To investigate whether curcumin may have in vivo protective effects against cisplatin ototoxicity by its direct scavenger activity and/or by curcumin-mediated upregulation of HO-1. Cisplatin-induced ototoxicity is a major dose-limiting side effect in anticancer chemotherapy. A protective approach to decrease cisplatin ototoxicity without compromising its therapeutic efficacy remains a critical goal for anticancer therapy. Recent evidences indicate that curcumin exhibits antioxidant, anti-inflammatory, and chemosensitizer activities. In male adult Wistar rats, a curcumin dose of 200 mg/kg, selected from a dose-response curve, was injected 1 hour before cisplatin administration and once daily for the following 3 days. A single dose of cisplatin (16 mg/kg) was administered intraperitoneally. Rats were divided as follows: 1) control, 2) curcumin control, 3) vehicle control, 4) cisplatin, 5) cisplatin+ vehicle, and 6) curcumin+cisplatin. ABRs were measured before and at Days 3 and 5 after cisplatin administration. Rhodamine-phalloidin staining, 4-hydroxy-2-nonenal and heme-oxigenase-1 immunostainings, and Western blot analyses were performed to assess and quantify OHC loss, lipid peroxidation, and the endogenous response to cisplatin-induced damage and to curcumin protection. Curcumin treatment attenuated hearing loss induced by cisplatin, increased OHC survival, decreased 4-HNE expression, and increased HO-1 expression. This preclinical study demonstrates that systemic curcumin attenuates ototoxicity and provides molecular evidence for a role of HO-1 as an additional mediator in attenuating cisplatin-induced damage.

  16. Study of embryotoxic effects of intranasally administred desloratadine on laboratory animals

    2017-04-01

    Full Text Available The study was conducted to detect possible changes in embryogenesis and negative effects of third generation antihistamine – desloratadine – after intranasal administration of 1.3 mg/m3 and 13.0 mg/m3 of the substance to laboratory animals during their prenatal period. In these circumstances, desloratadine does not cause any significant changes of embryogenesis parameters. Macroscopic examination of the fetus and placenta in animals of experimental groups did not reveal any pathology or physiological deviations from the norm. 13.0 mg/m3 concentration of the drug caused a decrease in the weight of embryos in comparison with control group of animals and physiological data, despite a well developed, without visible pathology, placenta. This neces­sitates an in-depth study of possible teratogenic effects of intranasally administred desloratadine to laboratory animals.

    2009-08-01

    To evaluate the effect of IV administration of tramadol hydrochloride on the minimum alveolar concentration of isoflurane (ISOMAC) that prevented purposeful movement of rabbits in response to a noxious stimulus. Six 6- to 12-month-old female New Zealand White rabbits. Anesthesia was induced and maintained with isoflurane in oxygen. A baseline ISOMAC was determined by clamping a pedal digit with sponge forceps until gross purposeful movement was detected or a period of 60 seconds elapsed. Subsequently, tramadol (4.4 mg/kg) was administered IV and the posttreatment ISOMAC (ISOMAC(T)) was measured. Mean +/- SD ISOMAC and ISOMAC(T) values were 2.33 +/- 0.13% and 2.12 +/- 0.17%, respectively. The ISOMAC value decreased by 9 +/- 4% after tramadol was administered. Plasma tramadol and its major metabolite (M1) concentrations at the time of ISOMAC(T) determination varied widely (ranges, 181 to 636 ng/mL and 32 to 61 ng/mL, respectively). Intervals to determination of ISOMAC(T) and plasma tramadol and M1 concentrations were not correlated with percentage change in the ISOMAC. Heart rate decreased significantly immediately after tramadol administration but by 10 minutes afterward was not different from the pretreatment value. Systolic arterial blood pressure decreased to approximately 60 mm Hg for approximately 5 minutes in 3 rabbits after tramadol administration. No adverse effects were detected. As administered, tramadol had a significant but clinically unimportant effect on the ISOMAC in rabbits. Higher doses of tramadol may provide clinically important reductions but may result in a greater degree of cardiovascular depression.

    Alterations in ovarian angiogenesis are common features in Polycystic Ovary Syndrome (PCOS) patients; the most studied of these alterations is the increase in vascular endothelial growth factor (VEGF) production by ovarian cells. Platelet-derived growth factor B (PDGFB) and D (PDGFD) are decreased in follicular fluid of PCOS patients and in the ovaries of a rat model of PCOS. In the present study, we aimed to analyze the effects of local administration of PDGFB on ovarian angiogenesis, follicular development and ovulation in a DHEA-induced PCOS rat model. Ovarian PDGFB administration to PCOS rats partially restored follicular development, decreased the percentage of cysts, increased the percentage of corpora lutea, and decreased the production of anti-Müllerian hormone. In addition, PDGFB administration improved ovarian angiogenesis by reversing the increase in periendothelial cell area and restoring VEGF levels. Our results shed light into the mechanisms that lead to altered ovarian function in PCOS and provide new data for potential therapeutic strategies. Copyright © 2016 Elsevier Ireland Ltd.

    Woolhandler, Steffie; Himmelstein, David U

    2014-01-01

    Doctors often complain about the burden of administrative work, but few studies have quantified how much time clinicians devote to administrative tasks. We quantified the time U.S. physicians spent on administrative tasks, and its relationship to their career satisfaction, based on a nationally representative survey of 4,720 U.S. physicians working 20 or more hours per week in direct patient care. The average doctor spent 8.7 hours per week (16.6% of working hours) on administration. Psychiatrists spent the highest proportion of their time on administration (20.3%), followed by internists (17.3%) and family/general practitioners (17.3%). Pediatricians spent the least amount of time, 6.7 hours per week or 14.1 percent of professional time. Doctors in large practices, those in practices owned by a hospital, and those with financial incentives to reduce services spent more time on administration. More extensive use of electronic medical records was associated with a greater administrative burden. Doctors spending more time on administration had lower career satisfaction, even after controlling for income and other factors. Current trends in U.S. health policy--a shift to employment in large practices, the implementation of electronic medical records, and the increasing prevalence of financial risk sharing--are likely to increase doctors' paperwork burdens and may decrease their career satisfaction.

    Amifostine (AMF), a radioprotectant, is FDA-approved for intravenous administration in cancer patients receiving radiation therapy (XRT). Unfortunately, it remains clinically underutilized due to adverse side effects. The purpose of this study is to define the pharmacokinetic profile of an oral AMF formulation potentially capable of reducing side effects and increasing clinical feasibility. Calvarial osteoblasts were radiated under three conditions: no drug, AMF, and WR-1065 (active metabolite). Osteogenic potential of cells was measured using alkaline phosphatase staining. Next, rats were given AMF intravenously or directly into the jejunum, and pharmacokinetic profiles were evaluated. Finally, rats were given AMF orally or subcutaneously, and blood samples were analyzed for pharmacokinetics. WR-1065 preserved osteogenic potential of calvarial osteoblasts after XRT to a greater degree than AMF. Direct jejunal AMF administration incurred a systemic bioavailability of 61.5%. Subcutaneously administrated AMF yielded higher systemic levels, a more rapid peak exposure (0.438 vs. 0.875 h), and greater total systemic exposure of WR-1065 (116,756 vs. 16,874 ng*hr/ml) compared to orally administered AMF. Orally administered AMF achieves a similar systemic bioavailability and decreased peak plasma level of WR-1065 compared to intravenously administered AMF, suggesting oral AMF formulations maintain radioprotective efficacy without causing onerous side effects, and are clinically feasible.

  3. Psilocybin-Induced Decrease in Amygdala Reactivity Correlates with Enhanced Positive Mood in Healthy Volunteers.

    The amygdala is a key structure in serotonergic emotion-processing circuits. In healthy volunteers, acute administration of the serotonin 1A/2A/2C receptor agonist psilocybin reduces neural responses to negative stimuli and induces mood changes toward positive states. However, it is little-known whether psilocybin reduces amygdala reactivity to negative stimuli and whether any change in amygdala reactivity is related to mood change. This study assessed the effects of acute administration of the hallucinogen psilocybin (.16 mg/kg) versus placebo on amygdala reactivity to negative stimuli in 25 healthy volunteers using blood oxygen level-dependent functional magnetic resonance imaging. Mood changes were assessed using the Positive and Negative Affect Schedule and the state portion of the State-Trait Anxiety Inventory. A double-blind, randomized, cross-over design was used with volunteers counterbalanced to receive psilocybin and placebo in two separate sessions at least 14 days apart. Amygdala reactivity to negative and neutral stimuli was lower after psilocybin administration than after placebo administration. The psilocybin-induced attenuation of right amygdala reactivity in response to negative stimuli was related to the psilocybin-induced increase in positive mood state. These results demonstrate that acute treatment with psilocybin decreased amygdala reactivity during emotion processing and that this was associated with an increase of positive mood in healthy volunteers. These findings may be relevant to the normalization of amygdala hyperactivity and negative mood states in patients with major depression. Copyright © 2015 Society of Biological Psychiatry.

    2001-09-15

    It is important for veterinary administrators to apply knowledge bases from other fields to their own unique administrative needs. For example, although some resources are written for business managers, the discussions of four key management competency areas, guidelines for mastering these skills, organizational assessment tools, and other self-help tools may provide interesting food-for-thought for veterinary administrators.(76) In developing their own administrative styles, administrators should seek to apply those principles that seem to intuitively fit with their personal research styles, work situations, managerial styles, administrative preferences, and unique organizational culture. Through strengthening their liaisons with community and university business programs, counseling agencies, employee assistance programs, and psychology researchers, administrators can continue to be exposed to and benefit from new paradigms for consideration in veterinary medical environments. Through these liaisons, the unique needs of veterinary medical environments are also communicated to individuals within the fields of psychology and business, thus stimulating new research that specifically targets veterinary medical environment leadership issues. Each field has unique contributions to help veterinary administrators work toward creating veterinary medical environments that are creative, energetic, visionary, pragmatic, and highly marketable in order to help administrators recruit and nurture the best and brightest veterinary researchers, teachers, and clinicians.

  5. Complex administrative procedures between administrative efficiency and the obligation to protect individual rights

    1982-01-01

    Due to their structural premise, administrative procedures possess an inordinate amount of influence, especially in complex situations of judicial decision making, to arrive at the ''right decision'' during the passing of binding regulatory ordinances. Since their system of organization is primarily subject to legislative influence, they are governed by the rules of administrative efficiency in the sense of extensive usage of performance - oriented governmental effectuation of constitutional rights. The demands for adequate judicial protection, of which wide administrative court procedure controls are part, will also serve the goal of reaching the ''right administrative decisions.'' (orig.) [de

    Full Text Available Cancer patient receive various cytotoxic drugs in association with antiemetic drugs such as 5HT3 receptor antagonists as their chemotherapy regimen. 5HT3 receptor antagonists have been reported to produce changes in ECG parameter. There are only a few studies about cardiovascular events of these drugs in patient receiving potentially cardiotoxic chemotherapies. The subject of this study is to evaluate ECG changes after administration of chemotherapeutic agents and granisetron (the most commonly used 5HT3 antagonist in Iran in adults with cancer. For this clinical trial study, all cancer patients referred to department of radiation oncology of Imam Hossein Hospital since August 2005 to March 2006 were evaluated if they had inclusion criteria. Granisetron (3 mg was infused intravenously over 30 seconds just a few minutes before chemotherapeutic agent administration. The 12-lead ECG recording was obtained before and 90 minutes after infusion of granisetron. One cardiologist determined PR, QRS, QTc intervals and heart rate of all ECGs. During the study period 54 patients fulfilled our criteria. With paired t-test, the PR and QTc intervals, but not QRS interval showed statistically significant prolongation after drug infusion (P < 0.0001, and heart rate showed statistically significant decrease (P < 0.0001. The ECG findings of chemotherapeutic agents and granisetron administration were prolongation of PR and QTc intervals and decrease of heart rate (P < 0.0001. Although these changes did not cause clinical signs, with keeping in mind that there may be possible drug-drug interactions and preexisting cardiac comorbidities in cancer patient, it seems reasonable and necessary to consider physical condition specifically cardiac condition and drug usage of each patient, while designing chemotherapy regimen and supportive drugs.

    Full Text Available Arsenic is a naturally occurring element that is ubiquitously present in the environment. High concentration of naturally occurring arsenic in drinking water is a major health problem in different parts of the world. Despite arsenic being a health hazard and a well documented carcinogen, no safe, effective and specific preventive or therapeutic measures are available. Among various recent strategies adopted, administration of an antioxidant has been reported to be the most effective. The present study was designed to evaluate the therapeutic efficacy of monoisoamyl dimercaptosuccinic acid (MiADMSA, administered either individually or in combination with taurine post chronic arsenic exposure in rats. Arsenic exposed male rats (25 ppm, sodium arsenite in drinking water for 24 weeks were treated with taurine (100 mg/kg, i.p., once daily, monoisoamyl dimercaptosuccinic acid (MiADMSA (50 mg/kg, oral, once daily either individually or in combination for 5 consecutive days. Biochemical variables indicative of oxidative stress along-with arsenic concentration in blood, liver and kidney were measured. Arsenic exposure significantly reduced blood δ-aminolevulinic acid dehydratase (ALAD activity, a key enzyme involved in the heme biosynthesis and enhanced zinc protoporphyrin (ZPP level. Clinical hematological variables like white blood cells (WBC, mean cell hemoglobin (MCH, and mean cell hemoglobin concentration (MCHC showed significant decrease with a significant elevation in platelet (PLT count. These changes were accompanied by significant decrease in superoxide dismutase (SOD activity and increased catalase activity. Arsenic exposure caused a significant decrease in hepatic and renal glutathione (GSH level and an increase in oxidized glutathione (GSSG. These biochemical changes were correlated with an increased uptake of arsenic in blood, liver and kidney. Administration of taurine significantly reduced hepatic oxidative stress however co-administration

    Full Text Available Objective: The present study was designed to investigate the putative antidepressant effects of crocin and crocetin, two major active ingredients of Crocus sativus L. (saffron using mice in two different regimens of acute and sub-acute administration. Material and Methods: In acute treatment, antidepressant-like activities of crocin and crocetin (10, 20 and 40 mg/kg, i.p. were evaluated using forced swim test (FST. In sub-acute study (21 times with 24-h intervals, antidepressant-like effects of oral administration of drugs were examined using FST and tail suspension test (TST. Locomotor activity and motor coordination were studied using open field and rotarod tests, respectively. Results: Acute treatment with crocin (40 mg/kg and crocetin (20 and 40 mg/kg produced antidepressant-like effect in FST without affecting the baseline locomotion in mice. Sub-acute oral administration of crocin significantly decreased immobility time only at the highest dose (100 mg/kg. Crocetin (12.5, 25 and 50 mg/kg was able to decrease immobility time in FST and TST. Locomotor activity and coordination of mice were not affected by crocin or crocetin. Conclusion: Since higher doses of crocin was required to show antidepressant effects, more efficacy of crocetin may be concluded. This observation provides further support for metabolism of crocin to crocetin following oral administration.

  14. The dual orexin/hypocretin receptor antagonist, almorexant, in the ventral tegmental area attenuates ethanol self-administration.

    Directory of Open Access Journals (Sweden)

    Subhashini Srinivasan

    Full Text Available Recent studies have implicated the hypocretin/orexinergic system in reward-seeking behavior. Almorexant, a dual orexin/hypocretin R(1 and R(2 receptor antagonist, has proven effective in preclinical studies in promoting sleep in animal models and was in Phase III clinical trials for sleep disorders. The present study combines behavioral assays with in vitro biochemical and electrophysiological techniques to elucidate the role of almorexant in ethanol and sucrose intake. Using an operant self-administration paradigm, we demonstrate that systemic administration of almorexant decreased operant self-administration of both 20% ethanol and 5% sucrose. We further demonstrate that intra-ventral tegmental area (VTA infusions, but not intra-substantia nigra infusions, of almorexant reduced ethanol self-administration. Extracellular recordings performed in VTA neurons revealed that orexin-A increased firing and this enhancement of firing was blocked by almorexant. The results demonstrate that orexin/hypocretin receptors in distinct brain regions regulate ethanol and sucrose mediated behaviors.

    Increased cortisol levels in obesity may contribute to the associated metabolic syndrome. In obesity, the activated innate immune system leads to increased interleukin (IL)-1β, which is known to stimulate the release of adrenocorticotropin hormone (ACTH). We hypothesized that in obesity IL-1 antagonism would result in downregulation of the hypothalamo-pituitary-adrenal axis, leading to decreased cortisol levels. In this prospective intervention study, we included 73 patients with obesity (body mass index [BMI] ≥30 kg/m2) and at least one additional feature of the metabolic syndrome. The primary end point was change in morning cortisol from baseline to after the administration of the IL-1 receptor antagonist (anakinra/Kineret®, total dose 3 × 100 mg). Secondary end points were effects on salivary cortisol and ACTH. Median age was 56 years, 50.7% of patients were female, and median BMI was 36.3 kg/m2. Median morning serum cortisol levels (nmol/L) decreased significantly after IL-1 antagonism [from baseline, 452 to 423; absolute difference, -38.7; 95% confidence interval (CI), -64 to -13.4; P = 0.0019]. Similar effects were found for salivary cortisol levels (-2.8; 95% CI, -4.4 to -1.3; P = 0.0007), ACTH levels (-2.2; 95% CI; -4.2 to -0.1; P = 0.038), systolic blood pressure (-5.2, 95% CI, -8.5 to -1.8; P = 0.0006), and heart rate (-2.9; 95% CI, -4.7 to -1.0; P = 0.0029). IL-1 antagonism in obese individuals with features of the metabolic syndrome leads to a decrease in serum cortisol, salivary cortisol, and ACTH levels along with a reduction in systolic blood pressure and heart rate.

    Caffeine is widely used for the treatment of apnea of prematurity (AoP) but whether this effect varies with sex is unknown. To shed some light on this question, we present a summary of data obtained on the effects of caffeine on the respiratory chemoreflexes and apnea frequency in 1- and 12-days old male and female rats. Caffeine was either administered as a single acute injection (10mg/kg, i.p.) or for 10 consecutive days (7.5mg/kg/day between 3 and 12days of life by gavage, simulating its clinical use). Acute caffeine had little effects on breathing in 1-day old male and female rats. In 12-days old female rats caffeine reduced the response to hypercapnia (not hypoxia) compared to males. During the steady state of hypoxia females had a lower frequency of apneas than males, and acute injection of caffeine decreased the frequency of apnea, suppressing the differences between males and females. In 12-days old rats chronic administration of caffeine stimulated basal breathing and decreased the frequency of apnea similarly in males and females. In response to hypoxia, chronic caffeine administration also masked the difference in respiratory frequency between males and females observed in control rats. Female rats had lower frequency of apnea than males with or without caffeine treatment. These observations indicate that sex influences the respiratory responses to caffeine and this effect seems to depend on the modality of administration (acute vs chronic) and environmental oxygen (normoxia vs hypoxia).

  17. Pharmacokinetics of repeated sodium salicylate administration to laying hens: evidence for time dependent increase in drug elimination from plasma and eggs.

    Directory of Open Access Journals (Sweden)

    Błażej Poźniak

    Full Text Available Salicylates were the first non-steroid anti-inflammatory drugs (NSAIDs to be used in any species and are still widely used in humans and livestock. However, the data on their pharmacokinetics in animals is limited, especially after repeated administration. Evidence exist that in chickens (Gallus gallus salicylate (SA may induce its own elimination. The aim of this study was to investigate salicylate pharmacokinetics and egg residues during repeated administration of sodium salicylate (SS to laying hens. Pharmacokinetics of SA was assessed during 14 d oral administration of SS at daily doses of 50 mg/kg and 200 mg/kg body weight to laying hens. On the 1st, 7th and 14th d a 24 h-long pharmacokinetic study was carried out, whereas eggs were collected daily. Salicylate concentrations in plasma and eggs were determined using high-performance liquid chromatography with ultraviolet detection and pharmacokinetic variables were calculated using a non-compartmental model. Mean residence time (MRT, minimal plasma concentration (Cmin, C16h and elimination half-life (T1/2el of SA showed gradual decrease in layers administered with a lower dose. Total body clearance (ClB increased. Layers administered with the higher dose showed a decrease only in the T1/2el. In the low dose group, SA was found only in the egg white and was low throughout the experiment. Egg whites from the higher dose group showed initially high SA levels which significantly decreased during the experiment. Yolk SA levels were lower and showed longer periods of accumulation and elimination. Repeated administration of SS induces SA elimination, although this effect may differ depending on the dose and production type of a chicken. Decreased plasma drug concentration may have clinical implications during prolonged SS treatment.

    1991-01-01

    In nonnuclear business, administrative procedures bring to mind such mundane topics as filing correspondence and scheduling vacation time. In the nuclear industry, on the other hand, administrative procedures play a vital role in assuring the safe operation of a facility. For some time now, industry focus has been on improving technical procedures. Significant efforts are under way to produce technical procedure requires that a validated technical, regulatory, and administrative basis be developed and that the technical process be established for each procedure. Producing usable technical procedures requires that procedure presentation be engineered to the same human factors principles used in control room design. The vital safety role of administrative procedures requires that they be just as sound, just a rigorously formulated, and documented as technical procedures. Procedure programs at the Tennessee Valley Authority and at Boston Edison's Pilgrim Station demonstrate that human factors engineering techniques can be applied effectively to technical procedures. With a few modifications, those same techniques can be used to produce more effective administrative procedures. Efforts are under way at the US Department of Energy Nuclear Weapons Complex and at some utilities (Boston Edison, for instance) to apply human factors engineering to administrative procedures: The techniques being adapted include the following

    To examine whether dexmedetomidine reduces the injection pain of propofol and rocuronium and to investigate whether the decrease in injection pain is associated with the known sedative action of dexmedetomidine. Randomized, double-blind, placebo-controlled clinical comparison study. Patients undergoing general anesthesia with intubation received 40 mg of 1% lidocaine (lidocaine group; n = 28), 0.25 μg/kg of dexmedetomidine (low-dose group; n = 27), 0.5 μg/kg of dexmedetomidine (subclinical dose group; n = 28), 1.0 μg/kg of dexmedetomidine (clinical dose group, n = 27), or normal saline (saline group; n = 28) before anesthetic induction. Pain associated with propofol and rocuronium injection was assessed using a 10-point verbal analog scale (VAS) and a 4-point withdrawal movement scale, respectively. The BIS value was measured 60 seconds after administration of the study drug, and at the time of rocuronium injection and intubation. The overall incidence of withdrawal movements due to rocuronium decreased significantly as the dose of dexmedetomidine increased (92.8%, 85.2%, 78.6%, and 51.9% in the saline, low-dose, subclinical dose, and clinical dose groups, respectively; P = 0.001). There was no significant difference in BIS values among the groups 60 seconds after study drug administration or at the time of rocuronium injection. Dexmedetomidine reduced pain associated with rocuronium injection in a dose-dependent manner. This effect was not associated with the decrease in BIS value. Copyright © 2014 Elsevier Inc.

    The changes in the academic world led to an increase in job demands and a decrease in the available job resources. In recent years, the positive image of work in academia has gradually blurred. The present study, within the theoretical framework of the job demands-resources model, aimed to analyse the relationship between some job demands (workload, work-family conflict and emotional dissonance) and some job resources (autonomy, supervisors' support and co-workers' support) and job satisfaction in a medium-sized Italian University, by observing the differences between the academic staff (professors and researchers) and the technical-administrative staff The research was conducted by administering a self-report questionnaire which allowed to detect job satisfaction and the mentioned variables. Respondents were 477 (177 from academic staff and 300 from technical-administrative staff). The analysis of variance (independent samples t-test) showed significant differences in variables of interest between academic staff and technical-administrative staff. Multiple regression pointed out that job autonomy is the main determinant of job satisfaction in the academic staff sample, whereas supervisor support is the main determinant of job satisfaction in the technical-administrative staff sample. This research represents one of the first Italian studies on these topics in the academic context and highlights the importance of further in-depth examinations of specific job dynamics for both teaching and technical-administrative staff. Among practical implications, the importance of keeping high levels of job autonomy for academic staff and of fostering an effective leadership development for technical-administrative staff emerged.

    2012-02-01

    Full Text Available Introduction: Hospital patient databases are typically used by administrative staff to estimate loss-profit ratios and to help with the allocation of hospital resources. These databases can also be very useful in following rehospitalization. This paper studies the recurrence of spine surgery patients in our hospital population based on administrative data analysis. Methods: Hospital data on 4,958 spine surgery patients operated between 2002 and 2009 were retrospectively reviewed. After sorting the cohort per ascending discharge date, the patient official name, consisting of first, middle and last names, was used as the variable determining duplicate cases in the SPSS statistical program, designating the first case in each group as primary. Yearly recurrence rate and change in procedure distribution were studied. In addition, hospital charges and length of stay were compared using the Wilcoxon-Mann-Whitney test. Results: Of 4,958 spine surgery patients 364 (7.3% were categorized as duplicate cases by SPSS. The number of primary cases from which duplicate cases emerged was 327 meaning that some patients had more than two spine surgeries. Among primary patients (N=327 the percentage of excision of intervertebral disk procedures was 33.3% and decreased to 15.1% in recurrent admissions of the same patients (N=364. This decrease was compensated by an increase in lumbar fusion procedures. On the other hand, the rate of cervical fusion remained the same. The difference in hospital charges between primary and duplicate patients was $2,234 for diskectomy, $6,319 for anterior cervical fusion, $8,942 for lumbar fusion – lateral technique, and $12,525 for lumbar fusion – posterior technique. Recurrent patients also stayed longer in hospital, up to 0.9 day in lumbar fusion – posterior technique patients. Conclusion: Spine surgery is associated with an increasing possibility of additional spine surgery with rising invasiveness and cost.

    Hemopressin, VD-hemopressin(α) and RVD-hemopressin(α) are hemoglobin α chain derived-peptides which have been found in mouse brain, and where they modulate cannabinoid (CB) receptor function. The nonapeptide hemopressin has been reported to inhibit feeding after both central and peripheral administration, possibly playing a role of antagonist/inverse agonist of CB1 receptors, and consequently blocking the orexigenic effects of endogenous cannabinoids. VD-hemopressin(α) and RVD- hemopressin(α), are N-terminal extended forms of hemopressin. VD-hemopressin(α) has CB1 agonist activity, and as such it has been shown to stimulate feeding. RVD-hemopressin(α) is reported to play a negative allosteric modulatory function on CB1 receptors, but there are no data on its possible effects on feeding and metabolic control. We have studied, in rats, the effects of 14 daily intraperitoneal (ip) injections of RVD-hemopressin(α) (10nmol). We found that RVD-hemopressin(α) treatment inhibited food intake while total body weight was not affected. The null effect on body weight despite diminished feeding could be related to decreased uncoupling protein 1 (UCP-1) gene expression in brown adipose tissue (BAT). We also investigated the underlying neuromodulatory effects of RVD-hemopressin(α) and found it to down regulate proopiomelanocortin (POMC) gene expression, together with norepinephrine (NE) levels, in the hypothalamus. In conclusion, RVD-hemopressin(α) administration has an anorectic effect, possibly related to inhibition of POMC and NE levels in the hypothalamus. Despite decreased food intake, body weight is not affected by RVD-hemopressin(α) treatment, possibly due to inhibition of UCP-1 gene expression in BAT.

    2015-07-01

    Full Text Available The structure of the legal system, through history until today mostly depends on law and policy which is conducted by the country. In European countries, there is position for historical and cultural conceptions for administrative judicature, differences and similarity that leave mark for solving administrative disputes. The obligation – an internal judicial reform to be established in legal system, is conducted by each of the countries after the breaking down and division of Social Federative Republic of Yugoslavia or SFRY due to following the European law for constitution of legitimacy and constitutionality of acts as well as implementing of independent administrative judicature. Analyze of the current condition regarding the independency and objectiveness of the judicature is necessary in our country and it is important to be seen how the conditions for working of the administrative judicature can be improved.

  8. The Alpha value decrease when the annual individual effective dose decreases?

    Sordi, Gian M.; Marchiusi, Thiago; Sousa, Jefferson de J.

    2008-01-01

    A recent IAEA publication tells that a few entities took different alpha values for maxima individual doses. Beyond to disregard the international agencies, that recommend only one alpha value for each country, the alpha values decreases when the individual doses decreases and the practice happens exactly the conversely as we will show in this paper. We will prove that the alpha value increase when the maximum individual doses decreases in a four different manner. The first one we call the theoretical conception and it is linked to the emergent of the ALARA policy and to the purpose that led to the 3/10 of the annual limits, for to decrease the individual doses as a first resort and a 1/10 as a last resort. The second prove will be based in a small mine example used in the ICRP publication number 55 concerning to the optimization and the quantitative decision-aiding techniques in radiological protection where we will determine the alpha value ranges in which each radiological protection options becomes the analytical solution. The third prove will be based in the determination of the optimized thickness example of a plane shielding for a radiation source exposed in the ICRP publication number 37. We will use, also, the numerical example provided there. Eventually, as four prove we will show that the alpha value dos not only increases with the maximum individual dose decrease, but also, with the shielding geometry. (author)

  9. Regional perfusion and oxygenation of tumors upon methylxanthine derivative administration

    Kelleher, Debra K.; Thews, Oliver; Vaupel, Peter

    1998-01-01

    Purpose: The use of methylxanthine derivatives has been postulated as a means of increasing tumor perfusion and thus ameliorating tumor hypoxia. The aim of this study was to quantify and compare the effects of three methylxanthine derivatives: pentoxifylline (PX), torbafylline (TB), and HWA 138 (HW) on tumor perfusion and oxygenation. Methods and Materials: Anesthetized Sprague Dawley rats with DS-sarcomas implanted subcutaneously onto the hind foot dorsum were used in this study. Mean arterial blood pressure (MABP) was measured throughout experiments. Regional red blood cell (RBC) flux was monitored using a multichannel laser Doppler device and tumor oxygenation on a more global level was assessed polarographically using an O 2 -sensitive catheter electrode. The methylxanthine derivatives were administered as a single dose intraperitoneally (for PX 50 mg/kg; for TB and HW 75 mg/kg). Results: Following drug administration, initial decreases in MABP down to 75% of baseline values were observed for all three substances. PX, HW, and TB caused initial transient reductions in mean RBC flux followed by gradual increases to values of 137 ± 27 %, 139 ± 14 %, and 122 ± 14 % respectively at t = 60 min. Following a small initial decrease upon drug administration, O 2 partial pressure (pO 2 ) rose to 160 ± 31 %, 153 ± 34 %, and 121 ± 11 % for PX, HW, and TB, respectively at t = 60 min. At the end of the observation period (t = 90 min), increases in RBC flux and pO 2 were still evident. When individual tumors were considered, a variety of patterns (including opposing effects) for changes in RBC flux were seen, not necessarily reflected in the mean values. Thus, while the methylxanthine derivatives caused an increased average tumor perfusion, there is evidence suggesting that a redistribution of tumor blood flow occurs which may amplify preexisting heterogeneity. Conclusions: Substantial improvements in tumor oxygenation and perfusion were observed after administration of

    2014-02-01

    To enhance the effect of anti-influenza-virus agent treatment, the effect of combined administration of oseltamivir phosphate and hochu-ekki-to (Japanese traditional herbal medicine, HET) on early viral clearance was examined. Senescence-accelerated mice were given HET in drinking water for 2 weeks, followed by intranasal infection with influenza A virus strain PR8. After 4 hours of infection, oseltamivir was administered orally for 5 days. The viral loads in the lungs of the group receiving combined treatment were dramatically lower when compared with the viral loads in the lungs of the group receiving oseltamivir alone. HET significantly increased the induction of IL-1β and TNF-α in the lungs of PR8-infected mice and stimulated alveolar macrophage phagocytosis. From these results, we conclude that these functions may be responsible the increased effect on viral load reduction. Here, we show that the combined administration of oseltamivir and HET is very useful for influenza treatment in senescence-accelerated mice.

  11. Judicial review of administrative silence

    Directory of Open Access Journals (Sweden)

    Radošević Ratko S.

    2015-01-01

    Full Text Available Administrative silence is a situation in which the competent authority, within the statutory deadline, has not issued an administrative act at the request of the party. In the case of administrative silence, given the fact that the citizens are unable to protect their rights and legal interests without an administrative act, they are provided with legal protection. In this case, the same legal relationship is created, directly on the basis of the statute, as in the situation in which the party's request is rejected. This means that the party may, under the conditions prescribed by the statute, initiate the procedure of judicial review of administrative silence. In the paper, the author explains the conditions under which the judicial review of administrative silence can be initiated and the role of the court in this judicial procedure.

    This study was conducted to compare the effects of administration of coconut oil (CO) and Moringa oleifera oil (MO) on testicular oxidative stress, sperm quality and steroidogenesis parameters in rats treated with mercury chloride (HgCl 2 ). After 15 days of oral administration of CO (2 ml kg -1 body weight) and MO (2 ml kg -1 body weight) along with intraperitoneal (i.p.) administration of HgCl 2 (5 mg kg -1 body weight) alone or in combination, we found that CO treatment did not protect against HgCl 2 -induced poor sperm quality (motility, count) as well as decreased testosterone level and 17β-hydroxysteroid dehydrogenase (17β-HSD) activity. Treatment with CO alone decreased glutathione (GSH), and glutathione peroxidase (GSH-Px) activities and increased malondialdehyde (MDA) level in rat's testis, whereas MO did not change these parameters. Cotreatment with MO prevented HgCl 2 -induced testicular catalase (CAT) and superoxide dismutase (SOD) activities, poor sperm quality and low testosterone level and also blocks the adverse effect of CO+HgCl 2 (2 ml kg -1 body weight + 5 mg kg -1 body weight) on the investigated endpoints. In conclusion, MO and not CO decreased the deleterious effects of HgCl 2 on sperm quality and steroidogenesis in rats and also strengthen the antioxidant defence of the testes. Therefore, MO is beneficial as an antioxidant in HgCl 2 -induced oxidative damage. © 2016 Blackwell Verlag GmbH.

    1975-01-01

    Using a radioimmunoassay (RIA) which is sensitive and highly specific to lutenizing hormone releasing factors (LRF, LH-RF), diminution of an exogeously administered synthetic LH-RF in the blood and the movement of LH released into the blood from the anterior lobe of hypopysis were examined on healthy adult males. The blood LH-RF level after an intravenous administration of 200 μg of synthetic LH-RF reached a maximum (mean, 35.0 ng/ml serum) 2.5 minutes after administration, followed by a rapid decrease, and was as low as 1.0 ng/ml serum 30 minutes after administration. The diminution of the exogenous LH-RF from the blood was rapidest 2.5-15 minutes after administration (t1/2=3.9 minutes) and slowest (t1/2=7.9 minutes) 15-30 minutes after administration. On the other hand, when 200 μg of the synthetic LH-RF was administered intramuscularly, LH-RF appeared only slightly in the blood 2.5 minutes after administration, and the maximum level (10 minutes after administration) was only 1.6 ng/ml serum. It diminished from the blood drawing lenient curve. The blood LH level continued to rise significantly starting 5 minutes after administration of 200 μg of the synthetic LH-RF both in intravenous and intramuscular cases, showing hardly any differences between them. The blood endogenous LH-RF level prior to the synthetic LH-RF administration was below the measurable sensitivity (10 pg/tupe). (Mukohata, S.)

  1. Neonatal morphine enhances nociception and decreases analgesia in young rats.

    Science.gov (United States)

    Zhang, Guo Hua; Sweitzer, Sarah M

    2008-03-14

    The recognition of the impact of neonatal pain experience on subsequent sensory processing has led to the increased advocacy for the use of opioids for pain relief in infants. However, following long-term opioid exposure in intensive care units more than 48% of infants exhibited behaviors indicative of opioid abstinence syndrome, a developmentally equivalent set of behaviors to opioid withdrawal as seen in adults. Little is known about the long-term influence of repeated neonatal morphine exposure on nociception and analgesia. To investigate this, we examined mechanical and thermal nociception on postnatal days 11, 13, 15, 19, 24, 29, 39 and 48 following subcutaneous administration of morphine (3 mg/kg) once daily on postnatal days 1-9. The cumulative morphine dose-response was assessed on postnatal days 20 and 49, and stress-induced analgesia was assessed on postnatal days 29 and 49. Both basal mechanical and thermal nociception in neonatal, morphine-exposed rats were significantly lower than those in saline-exposed, handled-control rats and naive rats until P29. A rightward-shift of cumulative dose-response curves for morphine analgesia upon chronic neonatal morphine was observed both on P20 and P49. The swim stress-induced analgesia was significantly decreased in neonatal morphine-exposed rats on P29, but not on P49. These data indicate that morphine exposure equivalent to the third trimester of gestation produced prolonged pain hypersensitivity, decreased morphine antinociception, and decreased stress-induced analgesia. The present study illustrates the need to examine the long-term influence of prenatal morphine exposure on pain and analgesia in the human pediatric population.

  2. Optimizing the electronic health record to standardize administration and documentation of nutritional supplements.

    Malnutrition in hospitalized patients is a major cause for hospital re-admission, pressure ulcers and increased hospital costs. Methods to improve the administration and documentation of nutritional supplements for hospitalized patients are needed to improve patient care, outcomes and resource utilization. Staff at a medium-sized academic health science center hospital in the southeastern United States noted that nutritional supplements ordered for patients at high risk for malnutrition were not offered or administered to patients in a standardized manner and/or not documented clearly in the electronic health record as per prescription. This paper reports on a process improvement project that redesigned the ordering, administration and documentation process of oral nutritional supplements in the electronic health record. By adding nutritional products to the medication order sets and adding an electronic nutrition administration record (ENAR) tab, the multidisciplinary team sought to standardize nutritional supplement ordering, documentation and administration at prescribed intervals. This process improvement project used a triangulated approach to evaluating pre- and post-process change including: medical record reviews, patient interviews, and nutrition formula room log reports. Staff education and training was carried out prior to initiation of the system changes. This process change resulted in an average decrease in the return of unused nutritional formula from 76% returned at baseline to 54% post-process change. The process change resulted in 100% of nutritional supplement orders having documentation about nutritional medication administration and/or reason for non-administration. Documentation in the ENAR showed that 41% of ONS orders were given and 59% were not given. Significantly more patients reported being offered the ONS product (p=0.0001) after process redesign and more patients (5% before ENAR and 86% after ENAR reported being offered the correct

  4. Effect of continuous intravenous administration of a 50% dextrose solution on phosphorus homeostasis in dairy cows.

    2006-08-01

    To determine the effect of continuous IV administration of 50% dextrose solution on phosphorus homeostasis in lactating dairy cows. Clinical trial. 4 multiparous Jersey cows. Cows were administered 50% dextrose solution IV (0.3 g/kg/h [0.14 g/lb/h]) for 5 days. Plasma concentrations of glucose, immune-reactive insulin (IRI), and phosphorus were determined before, during, and for 72 hours after dextrose infusion. Phosphorus intake and losses of phosphorus in urine, feces, and milk were determined. Each cow received a sham treatment that included instrumentation and sampling but not administration of dextrose. Plasma glucose, IRI, and phosphorus concentrations were stable during sham treatment. Plasma phosphorus concentration decreased rapidly after onset of dextrose infusion, reaching a nadir in 24 hours and remaining less than baseline value for 36 hours. Plasma phosphorus concentration increased after dextrose infusion was stopped, peaking in 6 hours. Urinary phosphorus excretion did not change during dextrose infusion, but phosphorus intake decreased because of reduced feed intake, followed by decreased fecal phosphorus loss and milk yield. Rapid changes in plasma phosphorus concentration at the start and end of dextrose infusion were temporally associated with changes in plasma glucose and IRI concentrations and most likely caused by compartmental shifts of phosphorus. Hypophosphatemia developed in response to hyperglycemia or hyperinsulinemia in dairy cows administered dextrose via continuous IV infusion. Veterinarians should monitor plasma phosphorus concentration when administering dextrose in this manner, particularly in cows with decreased appetite or preexisting hypophosphatemia.

  15. NEITHER FISH NOR FOWL: ADMINISTRATIVE JUDGES IN THE MODERN ADMINISTRATIVE STATE

    Directory of Open Access Journals (Sweden)

    Russell L. Weaver

    2010-10-01

    Full Text Available This article examines the role of administrative adjudication in the United States constitutional system. It begins by noting that such adjudication fits uncomfortably within a system of divided powers. Administrative judges, including administrative law judges [ALJs] (who have the highest level of protection and status, are considerably more circumscribed than ordinary Article III judges. Indeed, administrative judges are usually housed in the agencies for which they decide cases, rather than in independent adjudicative bodies, and they do not always have the final say regarding the cases they decide. In many instances, the agency can appeal an adverse administrative judge’s decision directly to the head of the agency, and the agency head retains broad power to overrule the administrative judge’s determinations. In other words, the agency can substitute its judgment for that of the administrative judge regarding factual determinations, legal determinations, and policy choices. As a result, many administrative adjudicative structures involve difficult tradeoffs between independence, political control, and accountability. This article examines issues related to the status and power of administrative judges, as well as the constraints that have been imposed on administrative adjudicative authority, and explores whether those constraints continue to serve the purposes for which they were originally imposed. Cet article examine le rôle du règlement de différends dans le domaine administratif dans le cadre du système constitutionnel des États-Unis. Il note d’abord qu’une telle façon de régler les différends cadre difficilement avec un système où les pouvoirs sont divisés. Les juges administratifs, y inclus les juges de droit administratif (qui jouissent du niveau le plus élevé de protection et de statut, sont considérablement plus restreints que les juges ordinaires sous l’Article III.

    2013-09-01

    This article reviews the neuropsychiatric presentations elicited by spontaneous hypercortisolism and exogenous supraphysiologic glucocorticoids. Patients with Cushing disease and syndrome develop a depressive syndrome: irritable and depressed mood, decreased libido, disrupted sleep and cognitive decrements. Exogenous short-term glucocorticoid administration may elicit a hypomanic syndrome with mood, sleep and cognitive disruptions. Treatment options are discussed. Brain imaging and neuropsychological studies indicate elevated cortisol and other glucocorticoids are especially deleterious to hippocampus and frontal lobe. The research findings also shed light on neuropsychiatric abnormalities in conditions that have substantial subgroups exhibiting elevated and dysregulated cortisol: aging, major depressive disorder and Alzheimer's disease.

    2016-05-01

    Compared to age-matched healthy controls (n = 55), patients with amyotrophic lateral sclerosis (ALS) (n = 26) showed increased oxidative stress as indicated by a significantly increased percentage of oxidized coenzyme Q10 (%CoQ10) in total plasma coenzyme Q10, a significantly decreased level of plasma uric acid, and a significantly decreased percentage of polyunsaturated fatty acids in total plasma free fatty acids (FFA). Therefore, the efficacy of edaravone, a radical scavenger, in these ALS patients was examined. Among 26 ALS patients, 17 received edaravone (30 mg/day, one to four times a week) for at least 3 months, and 13 continued for 6 months. Changes in revised ALS functional rating scale (ALSFRS-R) were significantly smaller in these patients than in edaravone-untreated ALS patients (n = 19). Edaravone administration significantly reduced excursions of more than one standard deviation from the mean for plasma FFA levels and the contents of palmitoleic and oleic acids, plasma markers of tissue oxidative damage, in the satisfactory progress group (ΔALSFRS-R ≥ 0) as compared to the ingravescent group (ΔALSFRS-R Edaravone treatment increased plasma uric acid, suggesting that it is an effective scavenger of peroxynitrite. However, edaravone administration did not decrease %CoQ10. Therefore, combined treatment with agents such as coenzyme Q10 may further reduce oxidative stress in ALS patients.

    2017-04-01

    Studies have shown that oxidative stress is involved in the pathophysiology of bipolar disorder (BD). It is suggested that omega-3 (ω3) fatty acids are fundamental to maintaining the functional integrity of the central nervous system. The animal model used in this study displayed fenproporex-induced hyperactivity, a symptom similar to manic BD. Our results showed that the administration of fenproporex, in the prevent treatment protocol, increased lipid peroxidation in the prefrontal cortex (143%), hippocampus (58%) and striatum (181%), and ω3 fatty acids alone prevented this change in the prefrontal cortex and hippocampus, whereas the co-administration of ω3 fatty acids with VPA prevented the lipoperoxidation in all analyzed brain areas, and the co-administration of ω3 fatty acids with Li prevented this increase only in the prefrontal cortex and striatum. Moreover, superoxide dismutase (SOD) activity was decreased in the striatum (54%) in the prevention treatment, and the administration of ω3 fatty acids alone or in combination with Li and VPA partially prevented this inhibition. On the other hand, in the reversal treatment protocol, the administration of fenproporex increased carbonyl content in the prefrontal cortex (25%), hippocampus (114%) and striatum (91%), and in prefrontal coxter the administration of ω3 fatty acids alone or in combination with Li and VPA reversed this change, whereas in the hippocampus and striatum only ω3 fatty acids alone or in combination with VPA reversed this effect. Additionally, the administration of fenproporex resulted in a marked increase of TBARS in the hippocampus and striatum, and ω3 fatty acids alone or in combination with Li and VPA reversed this change. Finally, fenproporex administration decreased SOD activity in the prefrontal cortex (85%), hippocampus (52%) and striatum (76%), and the ω3 fatty acids in combination with VPA reversed this change in the prefrontal cortex and striatum, while the co-administration of

    Full Text Available Objective: The purpose of this study was to analyze the effects of exposure to rhodamine B on ovarian oxidative stress, ovarian follicles, hormone 17beta-estradiol and thickness of endometrium. Methods: A total of 28 female rats were divided into four groups consisting of control; groups treated with rhodamine B at doses of 4.5; 9, and 18 milligram/200 gram body weight. Rhodamine B was administered orally for 36 days with the probe. Analysis of MDA level was done spectrophotometrically. Analysis of the number of ovarian follicles and thickness of endometrium was done histopathologically by hematoxylin eosin staining. Analysis of 17-estradiol level was done by ELISA. Results: Rhodamine B administered in different doses in female rats can increase ovarian MDA levels significantly than the control (P 0.05. Administration of rhodamine B of the second and third doses in female rats can reduce the number of primary, secondary, and De Graaf follicles significantly compared to the control (P 0.05. Administration of rhodamine B of the second and third doses in female rats can reduce 17-estradiol level significantly compared to the control (P 0.05. The administration of rhodamine B could reduce thickness of endometrium significantly compared to the control (P 0.05. Conclusion: It was concluded that administration of rhodamine B triggered ovarian toxicity through oxidative stress, a decrease in the number of follicles, and decreased level of 17-estradiol which ultimately lowered the thickness of endometrium.

    2006-02-01

    To evaluate the effects of intranasal administration of midazolam and xylazine (with or without ketamine) and detomidine and their specific antagonists in parakeets. Prospective study. 17 healthy adult Ring-necked Parakeets (Psittacula krameri) of both sexes (mean weight, 128.83+/-10.46 g [0.28+/-0.02 lb]). The dose of each drug or ketamine-drug combination administered intranasally that resulted in adequate sedation (ie, unrestrained dorsal recumbency maintained for >or=5 minutes) was determined; the onset of action, duration of dorsal recumbency, and duration of sedation associated with these treatments were evaluated. The efficacy of the reversal agents flumazenil, yohimbine, and atipamezole was also evaluated. In parakeets, intranasal administration of midazolam (7.3 mg/kg [3.32 mg/lb]) or detomidine (12 mg/kg [5.45 mg/lb]) caused adequate sedation within 2.7 and 3.5 minutes, respectively. Combinations of midazolam (3.65 mg/kg [1.66 mg/lb]) and xylazine (10 mg/kg [4.55 mg/lb]) with ketamine (40 to 50 mg/kg [18.2 to 22.7 mg/lb]) also achieved adequate sedation. Compared with detomidine, duration of dorsal recumbency was significantly longer with midazolam. Intranasal administration of flumazenil (0.13 mg/kg [0.06 mg/lb]) significantly decreased midazolam-associated recumbency time. Compared with the xylazineketamine combination, duration of dorsal recumbency was longer after midazolam-ketamine administration. Intranasal administration of flumazenil, yohimbine, or atipamezole significantly decreased the duration of sedation induced by midazolam, xylazine, or detomidine, respectively. Intranasal administration of sedative drugs appears to be an acceptable method of drug delivery in Ring-necked Parakeets. Reversal agents are also effective when administered via this route.

    Within 20 minutes after administration into the right lateral ventricle, precursor balance is achieved in both cerebral hemispheres, the brain stem and the cerebellum. A different course was observed in the medulla oblongata and the spinal cord. Twenty minutes following administration of the precursor, the amount of radioactivity decreased in the following order of sequence: the right hemisphere, the brain stem, the cerebellum, the left hemisphere, the medulla oblongata, and the spinal cord. Of the total amount of phosphates in the acid-soluble fraction of the whole brain and cerebellum, inorganic phosphates constxtute 50%, and there are no differences between the two parts. 60 minutes after administration of the labelled phosphate, the specific activity of total phosphates in the acid-soluble fraction of the brain and cerebellum is higher than the specific activity of inorganic phosphates.

  4. The nucleic acid metabolism in rat liver after single and long-term administration of tritium oxide

    International Nuclear Information System (INIS)

    Shorokhova, V.B.

    1984-01-01

    It was shown that after a single administration of tritiUm oxide in a dose of 22.2 MBq/g body mass the liver mass increased, the concentration of nucleic acids decreased and the biosynthesjs rate increased dUring a one-month observation. By the end of the observation period (the first year) the parameters under study were normalized. The long-term administration of tritium oxide in daily doses of 0.37, 0.925 and 1.85 MBq/g body mass caused changes in the nucleac acid metabolism which were less manifest (at early times), than in the case of a single injection. At the same time, the long-term administration of tritium oxide in the dose of 0.925 MBq/g caused a substantial disturbance of the nucleic acid metabolism at later times (after 2-9 months)

    2010-12-01

    Full Text Available The economic-financial crisis made its presence felt through more or less shy signals. All companies from the international and national market started to feel the crisis’s negative effects, several declaring bankruptcy, or diminishing temporary their activity. The consequences are multiples: the unemployment’s rate increase, the decreasing of the purchase power and reducing the goods demand from the luxury ones up to the one for consumption etc. Under these circumstances, companies have to avoid the immobilization of financial resources in products stocks that cannot be sold in the near future period, because otherwise would attract the danger of costs increasing, cashing decrease and generation of loses that may endanger the companies capacity of surpassing the present crisis. Therefore, all companies, no matter their size, should find during this period means of efficient stocks administration.

  17. The effect of prophylactic antipyretic administration on post-vaccination adverse reactions and antibody response in children: a systematic review.

    Full Text Available Prophylactic antipyretic administration decreases the post-vaccination adverse reactions. Recent study finds that they may also decrease the antibody responses to several vaccine antigens. This systematic review aimed to assess the evidence for a relationship between prophylactic antipyretic administration, post-vaccination adverse events, and antibody response in children.A systematic search of major databases including MEDLINE and EMBASE was carried out till March 2014. Randomized controlled trials (RCTs comparing prophylactic antipyretic treatment versus placebo post-vaccination in children ≤ 6 years of age were included. Two reviewers independently applied eligibility criteria, assessed the studies for methodological quality, and extracted data [PROSPERO registration: CRD42014009717].Of 2579 citations retrieved, a total of 13 RCTs including 5077 children were included in the review. Prophylactic antipyretic administration significantly reduced the febrile reactions (≥ 38.0 °C after primary and booster vaccinations. Though there were statistically significant differences in the antibody responses between the two groups, the prophylactic PCM group had what would be considered protective levels of antibodies to all of the antigens given after the primary and booster vaccinations. No significant difference in the nasopharyngeal carriage rates (short-term and long-term of H. influenzae or S. pneumoniae serotypes was found between the prophylactic and no prophylactic PCM group. There was a significant reduction in the local and systemic symptoms after primary, but not booster vaccinations.Though prophylactic antipyretic administration leads to relief of the local and systemic symptoms after primary vaccinations, there is a reduction in antibody responses to some vaccine antigens without any effect on the nasopharyngeal carriage rates of S. pneumoniae & H. influenza serotypes. Future trials and surveillance programs should also aim at

    2004-01-01

    The inhibitory influence of exogenous dextrose on glucose production has been shown to be less pronounced during injury and sepsis. This protocol was designed to investigate the effect of i.v. hypocaloric dextrose on glucose metabolism during elective abdominal surgery. Fourteen patients with rectal cancer were studied under fasting conditions and toward the end of a 3-hour infusion of dextrose (2 mg.kg-1 per minute) either in absence (control group, n = 7) or presence of colonic surgery (surgery group, n = 7). Endogenous glucose production was determined by using primed continuous infusions of [6,6-2H2]glucose before and during dextrose administration. We also measured the plasma concentrations of glucose, lactate, cortisol, glucagon, and insulin. The administration of dextrose decreased the endogenous glucose production in all patients (p dextrose infusion in both groups (p Dextrose infusion increased the plasma insulin concentrations to the same extent in both groups (p dextrose on endogenous glucose production.

    1981-01-01

    The effect of diabetes mellitus on the synthesis and secretion of thyroid hormone ws investigated in mice with streptozotocin-induced diabetes. Thyroid glands were labeled in vivo with 131I for 2 h. In control animals, TSH stimulated the synthesis of PB127I and 131I-labeled iodothyronines and simultaneously decreased the proportion of 131I-. These effects of TSH were not observed in diabetic animals but were demonstrable in diabetic animals treated with insulin. For studies of hormone secretion, labeled thyroid glands were cultured in vitro in medium containing 1 mM mononitrotyrosine. The rate of the hydrolysis of labeled thyroglobulin was measured as the proportion of 131I-labeled iodotyrosines and 131I-labeled iodothyronines recovered at the end of culture and was used as an index of thyroid secretion. TSH in vivo stimulated the rate of thyroglobulin hydrolysis for 6 h, with a peak occurring after 2 h. The diabetic mice had a diminished response to TSH, which improved on treatment with insulin. The addition of TSH and insulin to the culture medium significantly increased the rate of thyroglobulin hydrolysis in glands of diabetic mice over that resulting from the addition of dibutyryl cAMP alone. The generation of thyroidal cAMP in response to TSH was higher in diabetic mice than in controls. The rise in plasma T4 and T3 2 h after the administration of TSH was less in diabetic mice than in control mice or diabetic mice treated with insulin. Our studies, therefore, indicate that the thyroidal response to TSH is decreased in diabetes mellitus. The defect appears to be at a step beyond the generation of cAMP

    Recommended for decades, the therapeutic value of adrenaline (epinephrine) in the resuscitation of patients with out-of-hospital cardiac arrest (OHCA) is controversial. To investigate the possible time-dependent outcomes associated with adrenaline administration by Emergency Medical Services personnel (EMS). A retrospective analysis of prospectively collected data from a near statewide cardiac resuscitation database between 1 January 2005 and 30 November 2013. Multivariable logistic regression was used to analyze the effect of the time interval between EMS dispatch and the initial dose of adrenaline on survival. The primary endpoints were survival to hospital discharge and favourable neurologic outcome. Data from 3469 patients with witnessed OHCA were analyzed. Their mean age was 66.3 years and 69% were male. An initially shockable rhythm was present in 41.8% of patients. Based on a multivariable logistic regression model with initial adrenaline administration time interval (AATI) from EMS dispatch as the covariate, survival was greatest when adrenaline was administered very early but decreased rapidly with increasing (AATI); odds ratio 0.94 (95% Confidence Interval (CI) 0.92-0.97). The AATI had no significant effect on good neurological outcome (OR=0.96, 95% CI=0.90-1.02). In patients with OHCA, survival to hospital discharge was greater in those treated early with adrenaline by EMS especially in the subset of patients with a shockable rhythm. However survival rapidly decreased with increasing adrenaline administration time intervals (AATI). Copyright © 2015 The Authors. Published by Elsevier Ireland Ltd.. All rights reserved.

    2018-01-17

    Endometritis is a postpartum complication that is more common after cesarean delivery. It frequently requires intravenous antibiotic administration, prolonged hospital stays, and carries a risk of sepsis or abscess formation. Precesarean vaginal preparation has been shown to decrease the risk of endometritis in patients who have labored or have ruptured membranes. The objective of this study was to assess the practical implementation of a protocol for vaginal cleansing prior to cesarean delivery and the subsequent effect on endometritis rates in a clinical setting. This is a before-after retrospective cohort study evaluating the first 6 months of implementation of a vaginal cleansing protocol at a single institution. The primary outcome was the rate of implementation. Secondary outcomes included endometritis and other postoperative complications. The rate of implementation after 6 months was 68.3% (p < .001) and postoperative endometritis rates decreased from 14.0% before implementation to 11.7% after implementation (p .49, OR 0.77, CI 0.36-1.62). Postoperative fever decreased from 22.3% to 18.3% (p .256, OR 0.70, CI 0.37-1.30) and infectious wound complications were 4.5% and 5.8%, respectively (p .76, OR 1.07, CI 0.69-3.64). Implementation of a protocol for vaginal cleansing prior to cesarean delivery in women with ruptured membranes or in labor has high uptake, but in almost a third of eligible women it was not performed. The implementation, has led to a clinical, although not statistical, decrease in postoperative endometritis. Continued research is needed to explore how to improve uptake of this quality improvement measure.

    To determine the pharmacokinetics and safety of voriconazole administered orally in single and multiple doses in Hispaniolan Amazon parrots (Amazona ventralis). 15 clinically normal adult Hispaniolan Amazon parrots. Single doses of voriconazole (12 or 24 mg/kg) were administered orally to 15 and 12 birds, respectively; plasma voriconazole concentrations were determined at intervals via high-pressure liquid chromatography. In a multiple-dose trial, voriconazole (18 mg/kg) or water was administered orally to 6 and 4 birds, respectively, every 8 hours for 11 days (beginning day 0); trough plasma voriconazole concentrations were evaluated on 3 days. Birds were monitored daily, and clinicopathologic variables were evaluated before and after the trial. Voriconazole elimination half-life was short (0.70 to 1.25 hours). In the single-dose experiments, higher drug doses yielded proportional increases in the maximum plasma voriconazole concentration (C(max)) and area under the curve (AUC). In the multiple-dose trial, C(max), AUC, and plasma concentrations at 2 and 4 hours were decreased on day 10, compared with day 0 values; however, there was relatively little change in terminal half-life. With the exception of 1 voriconazole-treated parrot that developed polyuria, adverse effects were not evident. In Hispaniolan Amazon parrots, oral administration of voriconazole was associated with proportional kinetics following administration of single doses and a decrease in plasma concentration following administration of multiple doses. Oral administration of 18 mg of voriconazole/kg every 8 hours would require adjustment to maintain therapeutic concentrations during long-term treatment. Safety and efficacy of voriconazole treatment in this species require further investigation.

    Full Text Available Background. The underlying mechanisms of N-Methyl-3,4-methylenedioxyamphetamine-MDMA-induced hepatotoxicity are still unknown. The aim of this study was to evaluate hepatic oxido-reductive status in the rats liver after the single and repeated administration of MDMA. Methods. MDMA was dissolved in distilled water and administered in the doses of 5 mg, 10 mg, 20 mg, and 40 mg/kg. The animals from the acute experiment were treated per os with the single dose of the appropriate solution, through the orogastric tube. The animals from the chronic experiment were treated per os, with the doses of 5, 10, or 20 mg/kg of MDMA every day during 14 days. The control groups were treated with water only. Eight hours after the last dose, the animals were sacrificed, dissected their livers were rapidly removed, frozen and stored at -70°C until the moment of analysis. The parameters of oxidative stress in the crude mitochondrial fractions of the livers were analyzed. Results. Superoxide dismutase (SOD activity increased in the livers of the animals that were treated with single doses of MDMA. Chronically treated animals showed the increased SOD activity only after the highest dose (20 mg/kg. The content of reduced glutathione decreased in both groups, but the depletion was much more expressed after the single administration. Lipid peroxidation index increased in dose-dependent manner in both groups, being much higher after the single administration. Conclusion. The increased index of lipid peroxidation and the decreased reduced glutathione levels suggested that MDMA application induced the state of oxidative stress in the liver. These changes were much more expressed after the single administration of MDMA.

  9. Pouteria ramiflora extract inhibits salivary amylolytic activity and decreases glycemic level in mice

    Full Text Available In this study, extracts of plant species from the Cerrado biome were assessed in order to find potential inhibitors of human salivary alpha-amylase. The plants were collected and extracts were obtained from leaves, bark, and roots. We performed a preliminary phytochemical analysis and a screening for salivar alpha-amylase inhibitory activity. Only three botanical families (Sapotaceae, Sapindaceae and Flacourtiaceae and 16 extracts showed a substantial inhibition (>75% of alpha-amylase. The ethanolic extracts of Pouteria ramiflora obtained from stem barks and root barks decreased amylolytic activity above 95% at a final concentration of 20 µg/mL. Thus, adult male Swiss mice were treated orally with P. ramiflora in acute toxicity and glycemic control studies. Daily administration with 25, 50 and 100 mg/kg of aqueous extract of P. ramiflora for eight days can reduce significantly body weight and blood glucose level in mice. These data suggest that the crude polar extract of P. ramiflora decreases salivary amylolytic activity while lowering the blood levels of glucose.

  13. Bromocriptine increased operant responding for high fat food but decreased chow intake in both obesity-prone and resistant rats

    Dopamine (DA) and DAD{sub 2} receptors (D2R) have been implicated in obesity and are thought to be involved in the rewarding properties of food. Osborne-Mendel (OM) rats are susceptible to diet induced obesity (DIO) while S5B/P (S5B) rats are resistant when given a high-fat diet. Here we hypothesized that the two strains would differ in high-fat food self-administration (FSA) and that the D2R agonist bromocriptine (BC) would differently affect their behavior. Ad-libitum fed OM and S5B/P rats were tested in a FSA operant chamber and were trained to lever press for high-fat food pellets under a fixed-ratio (FR1) and a progressive ratio (PR) schedule. After sixteen days of PR sessions, rats were treated with three different doses of BC (1, 10 and 20 mg/kg). No significant differences were found between the two strains in the number of active lever presses. BC treatment (10 mg/kg and 20 mg/kg) increased the number of active lever presses (10 mg/kg having the strongest effect) whereas it decreased rat chow intake in the home cage with equivalent effects in both strains. These effects were not observed on the day of BC administration but on the day following its administration. Our results suggest that these two strains have similar motivation for procuring high fat food using this paradigm. BC increased operant responding for high-fat pellets but decreased chow intake in both strains, suggesting that D2R stimulation may have enhanced the motivational drive to procure the fatty food while correspondingly decreasing the intake of regular food. These findings suggest that susceptibility to dietary obesity (prior to the onset of obesity) may not affect operant motivation for a palatable high fat food and that differential susceptibility to obesity may be related to differential sensitivity to D2R stimulation.

  14. Mice heterozygous for the Mdr2 gene demonstrate decreased PEMT activity and diminished steatohepatitis on the MCD diet.

    Igolnikov, Alexander C; Green, Richard M

    2006-03-01

    The administration of a methionine and choline deficient (MCD) diet to mice serves as an animal model of NASH. The multidrug resistant 2 (Mdr2) P-glycoprotein encodes for the canalicular phospholipid transporter, and Mdr2 (+/-) mice secrete 40% less phosphatidylcholine than wild-type mice. We have hypothesized that phosphatidylethanolamine-N-methyl transferase (PEMT) up-regulation is a consequence of MCD diet administration, and is important for the pathogenesis of steatohepatitis in this model. However, the effect of decreased phosphatidylcholine secretion and modulation of PEMT on the development of diet-induced steatohepatitis in Mdr2 (+/-) mice has not been explored. Thus, the purpose of the study is to examine the effects of the MCD diet on Mdr2 (+/-) mice. Mdr2 (+/-) and Mdr2 (+/+) mice were treated with an MCD or control diet for up to 30 days, and the severity of steatohepatitis, PEMT activity and hepatic S-adenosylmethionine (SAM), and S-adenosylhomocysteine (SAH) levels were measured. Serum ALT levels, hepatic inflammation, and PEMT activity were significantly lower, and hepatic SAM:SAH ratios were significantly higher in Mdr2 (+/-) mice at 7 and 30 days on the MCD diet. Mdr2 (+/-) mice have diminished susceptibility to MCD diet-induced NASH, which is associated with a relative decrease in PEMT activity and increased SAM:SAH ratios.

    We evaluated the inhibitory effects of whole body 60 Co-γ irradiation at a single low dose on alloxan-induced hyperglycemia in rats. (1) In rats that received alloxan, SOD activity in pancreas significantly decreased, but the decrease was inhibited by irradiation at a dose of 0.5 Gy. (2) Similarly, plasma peroxide, pancreatic peroxide, and blood glucose increased. However, the increase in pancreatic peroxide was inhibited by irradiation at a dose of 0.5 or 1.0 Gy and the increase in blood glucose by irradiation at 0.5 Gy. (3) After alloxan administration, degranulation was observed in cells, but this was inhibited by irradiation at 0.5 Gy. These results suggest that alloxan diabetes was inhibited by the increase of SOD activity in pancreas after low dose irradiation at 0.5 Gy. (author)

    Plasma levels of homovanillic acid (pHVA) following debrisoquine (DBQ) administration may be indicative of central dopaminergic activity. The effect of DBQ (10-20 mg) administration on pHVA in young healthy volunteers was studied to establish a protocol for use in de novo patients with Parkinson's disease. Subsequently, pHVA in de novo patients with Parkinson's disease were measured and compared to young healthy volunteers. Following DBQ (10 mg) administration to healthy volunteers, pHVA fell with time to a maximum of 62% of control values at 6 h. The decrease in pHVA was not affected by loading with DBQ (10 mg) 10 h previously (pHVA: 67.6 +/- 5.8% of preDBQ levels) or increasing the dose to 20 mg (56.1 +/- 11.8% of preDBQ levels) compared to a single 10 mg dose of debrisoquine (66.5 +/- 4.5% of preDBQ levels). pHVA was reduced in both de novo patients with Parkinson's disease and in healthy volunteers following DBQ (10 mg) administration. However, there was no difference in pHVA before or after DBQ administration when comparing the two groups. These results suggest that, following DBQ administration, pHVA does not reflect dopamine neuronal loss in de novo patients with Parkinson's disease, so it is unlikely to detect the disease before the clinical symptoms manifest themselves.

    To determine the efficacy of a long-acting oxyntomodulin (OXM) analogue, OXM6421, in inhibiting food intake and decreasing body weight in lean and diet-induced obese (DIO) rodents. The glucagon-like peptide-1 (GLP-1) receptor binding affinity and efficacy, sensitivity to enzymatic degradation in vitro and persistence in the circulation after peripheral administration were investigated for OXM6421 and compared with native OXM. The chronic effect of OXM6421 on food intake, body weight and energy expenditure was examined in lean rats, and its anti-obesity potential was evaluated in DIO mice. OXM6421 showed enhanced GLP-1 receptor binding affinity and cyclic adenosine monophosphate (cAMP) stimulation, and higher resistance to enzymatic degradation by dipeptidyl peptidase IV (DPP-IV) and neutral endopeptidase (NEP) compared with native OXM. OXM6421 persisted longer in the circulation than OXM after peripheral administration. Acute administration of OXM6421 potently inhibited food intake in lean rodents, with cumulative effects lasting up to 24 h. In lean rats, daily subcutaneous (s.c.) administration of OXM6421 caused greater weight loss than the pair-fed animals, and a higher rate of oxygen consumption than both the pair-fed and the saline controls. In DIO mice, continuous s.c. infusion of OXM6421 resulted in a significant weight loss, accompanied by an improvement in glucose homeostasis and an increase in circulating adiponectin levels. Once-daily s.c. administration of OXM6421 for 21 days caused sustained weight loss in DIO mice. OXM6421 induces negative energy balance in both lean and obese rodents, suggesting that long-acting OXM analogues may represent a potential therapy for obesity.

    The present study explores whether presenting specific palatable foods in close temporal proximity of stop signals in a go/no-go task decreases subsequent evaluations of such foods among participants with a relatively high appetite. Furthermore, we tested whether any decreased evaluations could mediate subsequent food choice. Participants first received a go/no-go task in which palatable foods were consistently linked to go cues or no-go cues within participants. Next, evaluation of the palatable foods was measured as well as food choice. Replicating previous work, results show that among participants with a relatively high appetite palatable foods associated with no-go cues are less often chosen as snacks compared to when these foods are associated with go cues, whereas this manipulation did not affect participants with a relatively low appetite. Moreover, this effect was completely mediated by decreased evaluation of the palatable foods that had been associated with the no-go cues, whereas evaluation of the foods associated with go cues did not mediate this effect. Results further showed that the devaluation effect of foods associated with no-go cues was independent of the amount of pairings (4 vs. 12 vs. 24) with the no-go cues. The current findings suggest that decreased food evaluation is a mechanism that explains effects of stop signals on food choice. PMID:24324451

    OBJECTIVE To determine whether prophylactic administration of valacyclovir hydrochloride versus initiation of treatment at the onset of fever would differentially protect horses from viral replication and clinical disease attributable to equine herpesvirus type-1 (EHV-1) infection. ANIMALS 18 aged mares. PROCEDURES Horses were randomly assigned to receive an oral placebo (control), treatment at detection of fever, or prophylactic treatment (initiated 1 day prior to viral challenge) and then inoculated intranasally with a neuropathogenic strain of EHV-1. Placebo or valacyclovir was administered orally for 7 or 14 days after EHV-1 inoculation or detection of fever (3 horses/group). Effects of treatment on viral replication and clinical disease were evaluated. Plasma acyclovir concentrations and viremia were assessed to determine inhibitory concentrations of valacyclovir. RESULTS Valacyclovir administration decreased shedding of virus and viremia, compared with findings for control horses. Rectal temperatures and clinical disease scores in horses that received valacyclovir prophylactically for 2 weeks were lower than those in control horses. The severity of but not the risk for ataxia was decreased by valacyclovir administration. Viremia was decreased when steady-state trough plasma acyclovir concentrations were > 0.8 μg/mL, supporting the time-dependent activity of acyclovir. CONCLUSIONS AND CLINICAL RELEVANCE Valacyclovir treatment significantly decreased viral replication and signs of disease in EHV-1-infected horses; effects were greatest when treatment was initiated before viral inoculation, but treatment was also effective when initiated as late as 2 days after inoculation. During an outbreak of equine herpesvirus myeloencephalopathy, antiviral treatment may be initiated in horses at various stages of infection, including horses that have not yet developed signs of viral disease.

    Administration in the social field is examined based on an analysis of its practices, the rationalist myth and its ideological dimensions. In this way, the article discusses the most frequently utilized concepts (administration, management, gerencia, gestión) and their etymologies; the limitations of teaching administration; the complexity of a practice marked by the dimensions of science, art and the social game; and the ideological question underlying the great thought factory that the general theory of administration has been since the start of the 19th century. The article reflects upon the need to construct a theory based in practice contextualized in the global south that goes beyond the classic frames of reference and, above all, to transform administration into a problem to be discussed outside of the knowledge that recognizes it as a technical practice.

  4. Chronic cocaine administration induces opposite changes in dopamine receptors in the striatum and nucleus accumbens

    1987-01-01

    A variety of clinical and animal data suggest that the repeated administration of cocaine and related psychomotor stimulants may be associated with a behavioral sensitization whereby the same dose of the drug results in increasing behavioral pathology. This investigation was designed to determine the effects of chronic cocaine administration on the binding of [ 3 H]sulpiride, a relatively specific ligand for D2 dopaminergic receptors, in the rat brain using in vitro homogenate binding and light microscopic quantitative autoradiographic methodologies. Chronic daily injections of cocaine (10 mg/kg, i.p.) for 15 days resulted in a significant decrease in the maximum concentration of sulpiride binding sites in the striatum and a significant increase in the maximum number of these binding sites in the nucleus accumbens. No significant differences in binding affinity were observed in either brain region. These data suggest that chronic cocaine administration may result in differential effects on D2 receptors in the nigro-striatal and mesolimbic dopaminergic systems

    The current retrospective chart review compared glycemic control and cost impact of two insulin administration systems, V-Go ® versus usual care with standard of care (SOC) insulin injections, in eight patients residing in a nursing home (NH). A total of 1,937 blood glucose (BG) values were collected over 61 days. Significant improvements were observed for the V-Go versus SOC group in time in range 100 mg/dL to 200 mg/dL (V-Go 59.09% vs. SOC 34.02%; p < 0.001), reduced BG fluctuations as measured by standard deviation (V-Go 61.2 vs. SOC 92.1; p < 0.001), and improved mean daily BG (V-Go 159.38 mg/dL vs. SOC 223.86 mg/dL; p < 0.001). The estimated A1c change, calculated from BG values, decreased from 8.9% to 7.2% in the V-Go group and increased from 9.0% to 9.4% in the SOC group. Compared to SOC, use of V-Go decreased the mean time for insulin administration by nursing staff by 26.3 minutes per patient per day and associated labor costs by $328.75 per patient per month. Insulin administration with V-Go may improve glycemic control and reduce administration costs compared to existing care in the NH setting. [Journal of Gerontological Nursing, 43(1), 10-16.].

    To compare time to loss of consciousness (LOC) and effective maintenance of anesthesia following intraosseous (IO) and IV administration of propofol in rabbits. Evaluation study. 24 New Zealand White rabbits. Rabbits were selected to receive IO (n = 6) or IV (6) bolus administration of 1% propofol (12.5 mg/kg [5.67 mg/lb]) only or an identical bolus of propofol IO (6) or IV (6) followed by a constant rate infusion (CRI; 1 mg/kg/min [0.45 mg/lb/min]) by the same route for 30 minutes. Physiologic variables were monitored at predetermined time points; time to LOC and durations of anesthesia and recovery were recorded. Following IO and IV bolus administration, mean time to LOC was 11.50 and 7.83 seconds, respectively; changes in heart rate, respiratory rate, oxygen saturation (as measured by pulse oximetry), and mean arterial blood pressure values were evident, but findings did not differ between groups. For the IO- and IV-CRI groups, propofol-associated changes in heart rate, oxygen saturation, and mean arterial blood pressure values were similar, and although mean arterial blood pressure decreased significantly from baseline, values remained > 60 mm Hg; respiratory rate decreased significantly during CRI in both groups, but remained higher in the IO-CRI group. Anesthesia and recovery time did not differ between the IO- and IV-CRI groups. In all evaluated aspects of anesthesia, IO administration of propofol was as effective as IV administration in rabbits. Results suggested that total IO anesthesia can be performed in rabbits with limited vascular access.

    In the present study we evaluated the long-term effects of lithium administration to a knock-out double transgenic mouse model (Smn-/-; SMN1A2G+/-; SMN2+/+) of Spinal Muscle Atrophy type III (SMA-III). This model is characterized by very low levels of the survival motor neuron protein, slow disease progression and motor neuron loss, which enables to detect disease-modifying effects at delayed time intervals. Lithium administration attenuates the decrease in motor activity and provides full protection from motor neuron loss occurring in SMA-III mice, throughout the disease course. In addition, lithium prevents motor neuron enlargement and motor neuron heterotopy and suppresses the occurrence of radial-like glial fibrillary acidic protein immunostaining in the ventral white matter of SMA-III mice. In SMA-III mice long-term lithium administration determines a dramatic increase of survival motor neuron protein levels in the spinal cord. These data demonstrate that long-term lithium administration during a long-lasting motor neuron disorder attenuates behavioural deficit and neuropathology. Since low level of survival motor neuron protein is bound to disease severity in SMA, the robust increase in protein level produced by lithium provides solid evidence which calls for further investigations considering lithium in the long-term treatment of spinal muscle atrophy.

Melatonin was administered in drinking water at a concentration of 4 μg/ml daily from 15:00 h to 8:00 h. The application was initiated 5 days prior to the fi rst NMU dose and lasted 15 days, i.e. during the promotion phase of tumour development, or long-term until the end of the experiment (week 20. Immobilization (2 h per day began on the third day after the second carcinogen application and lasted for 7 consecutive days. Short-term MEL administration to immobilized animals increased incidence by 22%, decreased tumour frequency per animal by 26% and reduced tumour volume gain (by 21% when compared to the immobilized group without MEL application. Decreased frequency per animal by 28% and more than a 40% decrease in tumour volume gain and cumulative volume were the most pronounced changes in the animals drinking MEL until the end of the experiment. Long-term MEL administration reduced the number and size of mammary tumours more markedly than its short-term administration. Melatonin decreased certain attributes of mammary carcinogenesis in female rats influenced by psychoemotional stress.

  18. The effect of the administration of iron on Ga-67 uptake in animal tumor and biodistribution

    In 1979 Larson reported that the uptake of Ga-67 in tumor cell was preceded by binding of the Ga-67 to transferrin. Since that time there have been many papers concerning changes in Ga-67 accumulation in experimental tumor by administration of iron before and after Ga-67 injection. This study was undertaken in the attempt to discern what changes are produced in Ga-67 images of tumor-bearing rabbits (VX-II) when iron was administered before and after Ga-67 injection. Additionally, the relationships between the change in the serum iron concentration in the tumor tissue in mice bearing Ehrlich's ascites tumor were studied. The following results were obtained. 1) The tumor uptake and biodistribution of Ga-67 following administration of iron in the form of Fesin (saccharated ferric oxide) or ferric-citrate is obviously diminished. This iron administration leads to an elevated excretion of Ga-67 from tumor and other organs except from bone. From this results, it was found that Ga-67 binds somewhat less avidity than iron to various iron transport protein. Accordingly, Ga-67 biodistribution may be markedly influenced by iron-loading. 2) The Ga-67 activity in blood following administration of iron was noted to suddenly markedly decrease. However, 24-48 hours after iron injection the Ga-67 activity in blood gradually increased. This result suggests that the Ga-67 displaced into the extravascular space by iron-loading reentered the vascular space when the iron concentration of serum returned to normal. 3) The accumulation of Ga-67 in the tumor and soft tissues was slightly decreased compared with controls after iron administration. However, the tumor to blood ratio (T/B) of Ga-67 in mice by iron loading was several time greater than that of Ga-67 alone because the clearance of Ga-67 from the blood was more accelated than that of tumor. The large tumor to blood ratio (T/B) would be advantageous in obtaining a more distinct tumor scan. (author)

  19. Behavioral and neurochemical effects of chronic administration of reserpine and SKF-38393 in rats

    Alterations in the density of dopamine receptor subtypes and behaviors mediated by the D1-selective agonist SKF-38393 were examined in rats treated chronically with reserpine, SKF-38393 or the combination of these drugs. Animals received either vehicle or reserpine (1 mg/kg s.c.) on days 1 to 28 and, in addition, half of each of these groups were treated with vehicle and half were treated with SKF-38393 (5-10 mg/kg s.c.) on days 15 to 29. Quantitative autoradiographic measurement of D1 receptors labeled with [ 3 H]SCH-23390 and D2 receptors labeled with [ 3 H]spiroperidol revealed that chronic administration of reserpine increased the density of both receptor subtypes in the nucleus accumbens and caudate-putamen, but not in the substantia nigra. Chronic administration of SKF-38393 alone did not alter D1 receptor density in any of these regions. However, chronic administration of the agonist in reserpinized animals decreased D1 receptor density in the nucleus accumbens, but not in the caudate-putamen or substantia nigra, demonstrating that this partial agonist can selectively down-regulate D1 receptors when endogenous dopaminergic tone is removed. The chronic drug treatments also altered behavioral responses. Chronic administration of SKF-38393 alone produced sensitization of the oral dyskinesia response elicited by a challenge injection of the agonist, but no significant change in the grooming response. Acute administration of SKF-38393 in rats treated with reserpine for 14 days produced stereotypy which was not altered after chronic administration of the agonist. Surprisingly, chronic administration of reserpine alone produced a spontaneous oral dyskinesia, which was blocked dose-dependently by the D2-selective antagonist spiroperidol. These findings are discussed in terms of their relevance to Parkinson's disease and tardive dyskinesia

    It has been reported that radon inhalation activates antioxidative functions in liver and has an antioxidative effect against hepatopathy similar to that of the antioxidative effects of ascorbic acid (VC) or α-tocopherol (VE). In this study, we examined the combined effects of radon inhalation and antioxidant vitamin administration on acute alcohol-induced hepatopathy in mice. ICR mice were subjected to intraperitoneal (i.p.) administration of alcohol after pretreating with air only (sham) or radon at a concentration of approximately 2000 Bq/m 3 for 24 hours and i.p. administration of VC (300 mg/kg body weight) or VE (300 mg/kg body weight). In mice injected with alcohol, the combined radon and antioxidant vitamins treatment significantly decreased the activities of glutamic oxaloacetic transaminase in serum compared to not only the alcohol-administered group (sham group), but also the radon inhalation with alcohol administration group or the vitamin and alcohol administration group. In addition, radon inhalation significantly increased the antioxidant level, in such as the catalase activity and the total glutathione content in liver compared to the sham group. These results suggested that the combined radon and antioxidant vitamin treatment could effectively inhibit alcohol-induced hepatopathy in mice without any antagonizing action. (author)

    Epidermal growth factor (EGF) is a cytoprotective peptide that has healing effects on the intestinal mucosa. We sought to determine whether systemic administration of EGF after the onset of sepsis improved intestinal integrity and decreased mortality. FVB/N mice were subjected to either sham laparotomy or 2 x 23 cecal ligation and puncture (CLP). Septic mice were further randomized to receive injection of either 150 microg kg(-1) d(-1) (i.p.) EGF or 0.9% saline (i.p.). Circulating EGF levels were decreased after CLP compared with sham animals but were unaffected by giving exogenous EGF treatment. In contrast, intestinal EGF levels increased after CLP and were further augmented by exogenous EGF treatment. Intestinal EGF receptor was increased after CLP, whether assayed by immunohistochemistry, real-time polymerase chain reaction, or Western blot, and exogenous EGF treatment decreased intestinal EGF receptor. Villus length decreased 2-fold between sham and septic animals, and EGF treatment resulted in near total restitution of villus length. Sepsis decreased intestinal proliferation and increased intestinal apoptosis. This was accompanied by increased expression of the proapoptotic proteins Bid and Fas-associated death domain, as well as the cyclin-dependent kinase inhibitor p21 cip1/waf Epidermal growth factor treatment after the onset of sepsis restored both proliferation and apoptosis to levels seen in sham animals and normalized expression of Bid, Fas-associated death domain, and p21 cip1/waf . To determine whether improvements in gut homeostasis were associated with a decrease in sepsis-induced mortality, septic mice with or without EGF treatment after CLP were followed 7 days for survival. Mortality decreased from 60% to 30% in mice treated with EGF after the onset of sepsis (P < 0.05). Thus, EGF may be a potential therapeutic agent for the treatment of sepsis in part due to its ability to protect intestinal integrity.

    Garlic (Allium sativum) is regarded as both a food and a medicinal herb. Increasing attention has focused on the biological functions and health benefits of garlic as a potentially major dietary component. Chronic garlic administration has been shown to enhance memory function. Evidence also shows that garlic administration in rats affects brain serotonin (5-hydroxytryptamine [5-HT]) levels. 5-HT, a neurotransmitter involved in a number of physiological functions, is also known to enhance cognitive performance. The present study was designed to investigate the probable neurochemical mechanism responsible for the enhancement of memory following garlic administration. Sixteen adult locally bred male albino Wistar rats were divided into control (n = 8) and test (n = 8) groups. The test group was orally administered 250 mg/kg fresh garlic homogenate (FGH), while control animals received an equal amount of water daily for 21 days. Estimation of plasma free and total tryptophan (TRP) and whole brain TRP, 5-HT, and 5-hydroxyindole acetic acid (5-HIAA) was determined by high-performance liquid chromatography with electrochemical detection. For assessment of memory, a step-through passive avoidance paradigm (electric shock avoidance) was used. The results showed that the levels of plasma free TRP significantly increased (P < .01) and plasma total TRP significantly decreased (P < .01) in garlic-treated rats. Brain TRP, 5-HT, and 5-HIAA levels were also significantly increased following garlic administration. A significant improvement in memory function was exhibited by garlic-treated rats in the passive avoidance test. Increased brain 5-HT levels were associated with improved cognitive performance. The present results, therefore, demonstrate that the memory-enhancing effect of garlic may be associated with increased brain 5-HT metabolism in rats. The results further support the use of garlic as a food supplement for the enhancement of memory.

    Full Text Available This study serves as an introduction to how virtual reality systems could be applied in public administration and what research tasks would be necessary to accomplish a project. E-government solutions began to emerge in public administration approximately a decade ago all over the developed world. Administration service facilities via the Internet did not attract many customers, because of the digital divide. E-government solutions were extended to mobile devices as well, but the expected breakthrough of usage has not ensued. The virtual reality form of public administration services recommended in this study has the most attractive outlay and the simplest navigation tools if compared to ‘traditional’ Internet based e-government. Thus, in accordance with the worldwide amazingly quick spread of the virtual reality systems of Second Life and 3 D types of entertainment, virtual reality applications in public administration could rely on a wide range of acceptance as well.

    The purpose of this study was to investigate whether prophylactic administration of melatonin to the mother throughout pregnancy could protect against ischemia/reperfusion (I/R)-induced oxidative brain damage in neonatal rats. The utero-ovarian arteries were occluded bilaterally for 30 min in female Wistar rats on day 16 of pregnancy to induce fetal ischemia. Reperfusion was achieved by releasing the occlusion and restoring circulation. A sham operation was performed in control rats. Melatonin solution or vehicle alone was administrated orally throughout pregnancy. We collected brain mitochondria from neonatal rats, evaluated mitochondrial structure by electron microscopy, and measured the respiratory control index (RCI) as an indicator of mitochondrial respiratory activity as well as the concentration of thiobarbituric acid-reactive substances (TBARS), a marker of oxidative stress. Histological analysis was performed at the Cornu Ammonis 1 (CA1) and Cornu Ammonis 3 (CA3) regions of the hippocampus. I/R significantly reduced the RCI and significantly elevated the concentration of TBARS. Melatonin treatment reversed these effects, resulting in values similar to that in untreated, sham-ischemic animals. Electron microscopic evaluation showed that the number of intact mitochondria decreased in the I/R group, while melatonin treatment preserved them. Histological analysis revealed a decrease in the ratio of normal to whole pyramidal cell number in the CA1 and CA3 regions in the I/R group. While melatonin administration protected against degeneration. These results indicate that prophylactic administration of melatonin to the mother throughout pregnancy may prevent I/R-induced oxidative brain damage in neonatal rats.

    Full Text Available Timely intravenous (IV thrombolysis for acute ischemic stroke is associated with better clinical outcomes. Acute stroke care implemented with "Stroke Code" (SC may increase IV tissue plasminogen activator (tPA administration. The present study aimed to investigate the impact of SC on thrombolysis.The study period was divided into the "pre-SC era" (January 2006 to July 2010 and "SC era" (August 2010 to July 2013. Demographics, critical times (stroke symptom onset, presentation to the emergency department, neuroimaging, thrombolysis, stroke severity, and clinical outcomes were recorded and compared between the two eras.During the study period, 5957 patients with acute ischemic stroke were admitted; of these, 1301 (21.8% arrived at the emergency department within 3 h of stroke onset and 307 (5.2% received IV-tPA. The number and frequency of IV-tPA treatments for patients with an onset-to-door time of <3 h increased from the pre-SC era (n = 91, 13.9% to the SC era (n = 216, 33.3% (P<0.001. SC also improved the efficiency of IV-tPA administration; the median door-to-needle time decreased (88 to 51 min, P<0.001 and the percentage of door-to-needle times ≤60 min increased (14.3% to 71.3%, P<0.001. The SC era group tended to have more patients with good outcome (modified Rankin Scale ≤2 at discharge (49.5 vs. 39.6%, P = 0.11, with no difference in symptomatic hemorrhage events or in-hospital mortality.The SC protocol increases the percentage of acute ischemic stroke patients receiving IV-tPA and decreases door-to-needle time.

    Patients with autism spectrum disorders (ASDs) exhibit core autistic symptoms including social impairments from early childhood and mostly show secondary disabilities such as irritability and aggressive behavior based on core symptoms. However, there are still no radical treatments of social impairments in these patients. Oxytocin has been reported to play important roles in multiple social behaviors dependent on social recognition, and has been expected as one of the effective treatments of social impairments of patients with ASDs. We present a case of a 16-year-old girl with autistic disorder who treated by long-term administration of oxytocin nasal spray. Her autistic symptoms were successfully treated by two month administration; the girl's social interactions and social communication began to improve without adverse effects. Her irritability and aggressive behavior also improved dramatically with marked decreases in aberrant behavior checklist scores from 69 to 7. This case is the first to illustrate long-term administration of oxytocin nasal spray in the targeted treatment of social impairments in a female with autistic disorder. This case suggests that long-term nasal oxytocin spray is promising and well-tolerated for treatment of social impairments of patients with ASDs.

    1985-01-01

    Enzyme albumin conjugates have been proposed as a means of increasing the efficacy of enzyme use in vivo and decreasing immune response to the enzyme. Particulate drug carriers, however, have a pronounced tendency to localize in the mononuclear phagocyte (reticuloendothelial) system. The authors have examined in mice the effect on phagocytic index, tissue distribution and organ size of continued administration of conjugates of alpha-glucosidase with either homologous or heterologous albumin. Mice received 10 X 2-mg injections of bovine serum albumin (BSA) or mouse serum albumin (MSA), either free, polymerized or conjugated with alpha-glucosidase. Experiments involving BSA had to be terminated before the end of the experiment because of anaphylaxis, but these reactions were less severe to the polymerized albumin than to free albumin. Free BSA, BSA polymer and BSA-enzyme conjugates all caused a decrease in phagocytic index after six injections. Mice receiving MSA showed no evidence of anaphylaxis, but mice receiving six or more injections of free MSA, MSA polymer or MSA-enzyme conjugate had significantly decreased phagocytic indices as compared to controls. Phagocytic indices had returned to normal by 7 days after the final injection. Tissue distribution of 125 I-labeled albumin preparations was determined in either naive or chronically injected mice

  3. Transcriptional Response in Mouse Thyroid Tissue after 211At Administration: Effects of Absorbed Dose, Initial Dose-Rate and Time after Administration.

    Directory of Open Access Journals (Sweden)

    Nils Rudqvist

    Full Text Available 211At-labeled radiopharmaceuticals are potentially useful for tumor therapy. However, a limitation has been the preferential accumulation of released 211At in the thyroid gland, which is a critical organ for such therapy. The aim of this study was to determine the effect of absorbed dose, dose-rate, and time after 211At exposure on genome-wide transcriptional expression in mouse thyroid gland.BALB/c mice were i.v. injected with 1.7, 7.5 or 100 kBq 211At. Animals injected with 1.7 kBq were killed after 1, 6, or 168 h with mean thyroid absorbed doses of 0.023, 0.32, and 1.8 Gy, respectively. Animals injected with 7.5 and 100 kBq were killed after 6 and 1 h, respectively; mean thyroid absorbed dose was 1.4 Gy. Total RNA was extracted from pooled thyroids and the Illumina RNA microarray platform was used to determine mRNA levels. Differentially expressed transcripts and enriched GO terms were determined with adjusted p-value 1.5, and p-value <0.05, respectively.In total, 1232 differentially expressed transcripts were detected after 211At administration, demonstrating a profound effect on gene regulation. The number of regulated transcripts increased with higher initial dose-rate/absorbed dose at 1 or 6 h. However, the number of regulated transcripts decreased with mean absorbed dose/time after 1.7 kBq 211At administration. Furthermore, similar regulation profiles were seen for groups administered 1.7 kBq. Interestingly, few previously proposed radiation responsive genes were detected in the present study. Regulation of immunological processes were prevalent at 1, 6, and 168 h after 1.7 kBq administration (0.023, 0.32, 1.8 Gy.

    We evaluated the inhibitory effects of whole body {sup 60}Co-{gamma} irradiation at a single low dose on alloxan-induced hyperglycemia in rats. (1) In rats that received alloxan, SOD activity in pancreas significantly decreased, but the decrease was inhibited by irradiation at a dose of 0.5 Gy. (2) Similarly, plasma peroxide, pancreatic peroxide, and blood glucose increased. However, the increase in pancreatic peroxide was inhibited by irradiation at a dose of 0.5 or 1.0 Gy and the increase in blood glucose by irradiation at 0.5 Gy. (3) After alloxan administration, degranulation was observed in cells, but this was inhibited by irradiation at 0.5 Gy. These results suggest that alloxan diabetes was inhibited by the increase of SOD activity in pancreas after low dose irradiation at 0.5 Gy. (author).

  5. Pharmacokinetics of oral neratinib during co-administration of ketoconazole in healthy subjects.

    2011-04-01

    The primary objective was to evaluate the pharmacokinetics of a single dose of neratinib, a potent, low-molecular-weight, orally administered, irreversible pan-ErbB (ErbB-1, -2, -4) receptor tyrosine kinase inhibitor, during co-administration with ketoconazole, a potent CYP3A4 inhibitor. This was an open-label, randomized, two-period, crossover study. Fasting healthy adults received a single oral dose of neratinib 240 mg alone and with multiple oral doses of ketoconazole 400 mg. Blood samples were collected up to 72 h after each neratinib dose. Plasma concentration data were analyzed using a noncompartmental method. The least square geometric mean ratios [90% confidence interval (CI)] of C(max) (neratinib+ketoconazole): C(max) (neratinib alone), and AUC(neratinib+ketoconazole): AUC(neratinib alone) were assessed. Twenty-four subjects were enrolled. Compared with neratinib administered alone, co-administration of ketoconazole increased neratinib C(max) by 3.2-fold (90% CI: 2.4, 4.3) and AUC by 4.8-fold (3.6, 6.5). Median t(max) was 6.0 h with both regimens. Ketoconazole decreased mean apparent oral clearance of neratinib from 346 lh(-1) to 87.1 lh(-1) and increased mean elimination half-life from 11.7 h to 18.0 h. The incidence of adverse events was comparable between the two regimens (50% neratinib alone, 65% co-administration with ketoconazole). Co-administration of neratinib with ketoconazole, a potent CYP3A inhibitor, increased neratinib C(max) by 3.2-fold and AUC by 4.8-fold compared with administration of neratinib alone. These results indicate that neratinib is a substrate of CYP3A and is susceptible to interaction with potent CYP3A inhibitors and, thus, dose adjustments may be needed if neratinib is administered with such compounds. © 2011 The Authors.

    Studies were conducted to evaluate the ocular penetration and systemic exposure to besifloxacin, a fluoroquinolone antibiotic, following topical ocular administration to animals and humans. Besifloxacin ophthalmic suspension (0.6%) was administered as a topical ocular instillation to pigmented rabbits, cynomolgus monkeys, and human subjects. At predetermined intervals after dosing, samples of ocular tissues and plasma were collected and analyzed for besifloxacin levels using HPLC/MS/MS methods. Besifloxacin demonstrated good ocular penetration in rabbits and monkeys, with rapid absorption and sustained concentrations observed in anterior ocular tissues through 24 h after a single administration. Maximum besifloxacin concentrations in conjunctiva, cornea, and aqueous humor of monkeys were 6.43 microg/g, 2.10 microg/g, and 0.796 microg/mL, respectively, after a single topical dose, and concentrations declined in these tissues with an apparent half-life of 5-14 h. Following a single topical ocular administration to humans, the maximum besifloxacin concentration in tears was 610 microg/g with concentrations decreasing to approximately 1.6 microg/g at 24 h. The resulting pharmacokinetic parameters for besifloxacin in human tears were evaluated relative to the MIC(90) values (microg/mL) for besifloxacin against Streptococcus pneumoniae (0.125), Staphylococcus aureus (0.25), Staphylococcus epidermidis (0.5), and Haemophilus influenzae (0.06). Following a single topical administration, the C(max)/MIC(90) ratios for besifloxacin in human tears were > or =1,220, and the AUC((0-24))/MIC(90) ratios were > or =2,500 for these relevant ocular pathogens. Following repeated 3-times daily (TID) topical ocular administration to human subjects with clinically diagnosed bacterial conjunctivitis, maximum besifloxacin concentrations in plasma were less than 0.5 ng/mL, on average. Taken together, the results of the current investigation provide a PK/PD-based rationale that supports the

    Titanium dioxide nanoparticles (TiO2 NPs) have been widely used in various consumer products, especially food and personal care products. Compared to the well-characterized adverse cardiovascular effect of inhaled ambient ultrafine particles, research on the health response to orally administrated TiO2 NPs is still limited. In our study, we performed an in vivo study in Sprague-Dawley rats to understand the cardiovascular effect of TiO2 NPs after oral intake. After daily gastrointestinal administration of TiO2 NPs at 0, 2, 10, 50 mg/kg for 30 and 90 days, heart rate (HR), blood pressure, blood biochemical parameters and histopathology of cardiac tissues was assessed to quantify cardiovascular damage. Mild and temporary reduction of HR and systolic blood pressure as well as an increase of diastolic blood pressure was observed after daily oral administration of TiO2 NPs for 30 days. Injury of cardiac function was observed after daily oral administration of TiO2 NPs for 90 days as reflected in decreased activities of lactate dehydrogenase (LDH), alpha-hydroxybutyrate dehydrogenase (HBDH) and creatine kinase (CK). Increased white blood cells count (WBC) and granulocytes (GRN) in blood as well as increased concentrations of tumor necrosis factor α (TNF α) and interleukin 6 (IL-6) in the serum indicated inflammatory response initiated by TiO2 NPs exposure. It was hypothesize that cardiac damage and inflammatory response are the possible mechanisms of the adverse cardiovascular effects induced by orally administrated TiO2 NPs. Data from our study suggested that even at low dose of TiO2 NPs can induce adverse cardiovascular effects after 30 days or 90 days of oral exposure, thus warranting concern for the dietary intake of TiO2 NPs for consumers.

    Background: Intraperitoneal adhesion formation is a serious postsurgical issue. Adhesions develop after damage to the peritoneum by surgery, irradiation, infection or trauma. Objectives: Using a rat model, we compared the effectiveness of systemic and intraperitoneally administered common immunosuppressive drugs for prevention of postoperative intraperitoneal adhesions. Materials and Methods: Peritoneal adhesions were induced in 98 female Wistar-Albino rats by cecal abrasion and peritoneal excision. Rats were randomly separated into seven groups, each containing fourteen rats, and the standard experimental model was applied to all of rats. 14 days later, rats were euthanized, intraperitoneal adhesions were scored and tissues were examined histologically using hematoxylin/eosin and Masson’s trichrome staining. Results: Throughout the investigation, no animal died during or after surgery. In all of experimental groups, decrease in fibrosis was statistically significant. Decrease in fibrosis was most prominently in intraperitoneal tacrolimus group (P = 0.000), and decrease was least in intraperitoneal cyclosporine group (P = 0.022). Vascular proliferation was significantly decreased in all experimental groups (P < 0.05) except for systemic tacrolimus group (P = 0.139). Most prominent reduction in vascular proliferation was in intraperitoneal tacrolimus group (P = 0.000). Conclusions: Administration of immunosuppressive drugs is effective for prevention of intraperitoneal adhesions. PMID:24693396
