  7. Comprehension of action negation involves inhibitory simulation.

    PubMed

    Foroni, Francesco; Semin, Gün R

    2013-01-01

    Previous research suggests that action language is comprehended by activating the motor system. We report a study, investigating a critical question in this research field: do negative sentences activate the motor system? Participants were exposed to sentences in the affirmation and negation forms while the zygomatic muscle activity on the left side of the face was continuously measured (Electromyography technique: EMG). Sentences were descriptions of emotional expressions that mapped either directly upon the zygomatic muscle (e.g., "I am smiling") or did not (e.g., "I am frowning"). Reading sentences involving the negation of the activity of a specific muscle (zygomatic major-"I am not smiling") is shown to lead to the inhibition of this muscle. Reading sentences involving the affirmative form instead ("I am smiling") leads to the activation of zygomatic mucle. In contrast, sentences describing an activity that is irrelevant to the zygomatic muscle (e.g., "I am frowning" or "I am not frowning") produce no muscle activity. These results extend the range of simulation models to negation and by implication to an abstract domain. We discuss how this research contributes to the grounding of abstract and concrete concepts.

  17. Joint action modulates motor system involvement during action observation in 3-year-olds.

    PubMed

    Meyer, Marlene; Hunnius, Sabine; van Elk, Michiel; van Ede, Freek; Bekkering, Harold

    2011-06-01

    When we are engaged in a joint action, we need to integrate our partner's actions with our own actions. Previous research has shown that in adults the involvement of one's own motor system is enhanced during observation of an action partner as compared to during observation of an individual actor. The aim of this study was to investigate whether similar motor system involvement is present at early stages of joint action development and whether it is related to joint action performance. In an EEG experiment with 3-year-old children, we assessed the children's brain activity and performance during a joint game with an adult experimenter. We used a simple button-pressing game in which the two players acted in turns. Power in the mu- and beta-frequency bands was compared when children were not actively moving but observing the experimenter's actions when (1) they were engaged in the joint action game and (2) when they were not engaged. Enhanced motor involvement during action observation as indicated by attenuated sensorimotor mu- and beta-power was found when the 3-year-olds were engaged in the joint action. This enhanced motor activation during action observation was associated with better joint action performance. The findings suggest that already in early childhood the motor system is differentially activated during action observation depending on the involvement in a joint action. This motor system involvement might play an important role for children's joint action performance. PMID:21479943

  5. Lights! Camera! Action Projects! Engaging Psychopharmacology Students in Service-based Action Projects Focusing on Student Alcohol Abuse

    PubMed Central

    Kennedy, Susan

    2016-01-01

    Alcohol abuse continues to be an issue of major concern for the health and well-being of college students. Estimates are that over 80% of college students are involved in the campus “alcohol culture.” Annually, close to 2000 students die in the United States due to alcohol-related accidents, with another 600,000 sustaining injury due to alcohol-related incidents (NIAAA, 2013). Students enrolled in a Psychopharmacology course engaged in action projects (community outreach) focused on alcohol abuse on our campus. Research has indicated that these types of projects can increase student engagement in course material and foster important skills, including working with peers and developing involvement in one’s community. This paper describes the structure and requirements of five student outreach projects and the final projects designed by the students, summarizes the grading and assessment of the projects, and discusses the rewards and challenges of incorporating such projects into a course.

  14. Involving students in experimental design: three approaches.

    PubMed

    McNeal, A P; Silverthorn, D U; Stratton, D B

    1998-12-01

    Many faculty want to involve students more actively in laboratories and in experimental design. However, just "turning them loose in the lab" is time-consuming and can be frustrating for both students and faculty. We describe three different ways of providing structures for labs that require students to design their own experiments but guide the choices. One approach emphasizes invertebrate preparations and classic techniques that students can learn fairly easily. Students must read relevant primary literature and learn each technique in one week, and then design and carry out their own experiments in the next week. Another approach provides a "design framework" for the experiments so that all students are using the same technique and the same statistical comparisons, whereas their experimental questions differ widely. The third approach involves assigning the questions or problems but challenging students to design good protocols to answer these questions. In each case, there is a mixture of structure and freedom that works for the level of the students, the resources available, and our particular aims. PMID:16161223

    1991-01-01

    The algorithms derived by Grossmann and Larson (1989) are further developed for rewriting expressions involving differential operators. The differential operators involved arise in the local analysis of nonlinear dynamical systems. These algorithms are extended in two different directions: the algorithms are generalized so that they apply to differential operators on groups and the data structures and algorithms are developed to compute symbolically the action of differential operators on functions. Both of these generalizations are needed for applications.

  16. (abstract) Student Involvement in the Pluto Mission

    NASA Technical Reports Server (NTRS)

    Weinstein, Stacy

    1994-01-01

    The Pluto Fast Flyby mission development baseline consists of 2 identical spacecraft (120 - 165 kg) to be launched to Pluto/ Charon in the late 1990s. These spacecraft are intended to fly by Pluto and Charon in order to perform various remote-sensing scientific investigations and have a mission development cost less than $400M (FY92$) through launch plus 30 days. The Pluto team is committed to involving students in all areas of mission development and operations. In November 1992, the Pluto team sent a request for information to industry and universities looking for ways to lower the mass and cost of the mission. A number of universities responded with creative and promising technological developments. In addition to contracts with industry and other federal labs, contracts were signed with schools which allowed students to apply their research, enabling the Pluto team to use valuable resources on a variety of advanced technology endeavors. Perhaps the most exciting aspect of these investigations was that the deliverables that the students produced were not just final reports, but actual prototype hardware complete with write-ups on lessons learned in machining, programming, and design. Another exciting development was a prototype adapter competition in which 7 universities competed to design, build, and test their idea of a lightweight spacecraft-propulsion stack adapter. Georgia Tech won with an innovative dodecahedron composite lattice cone. Other students from other universities were involved as well. All in all, over 40 students from 20 different colleges made significant contributions to the Pluto Fast Flyby mission development through their efforts. This paper will give an overview of Pluto student involvement, the technologies which they examined, and useful results for the mission.

  1. Alpha adrenoceptor subtypes involved in the emetic action in dogs.

    PubMed

    Hikasa, Y; Ogasawara, S; Takase, K

    1992-05-01

    In order to assess the involvement of alpha-1 and alpha-2 adrenoceptors in emesis, the emetic effect of eight alpha agonists was studied in dogs. The i.m. administration of each agonist elicited dose-dependent emesis. The order of potency in inducing emesis was: clonidine greater than oxymetazoline greater than tramazoline greater than naphazoline greater than xylazine greater than epinephrine greater than methoxamine = phenylephrine. The clonidine-induced emesis was antagonized by adrenoceptor antagonists showing alpha-2 blocking activity, yohimbine, tolazoline and phentolamine. Among these antagonists, yohimbine was the most effective. The alpha-1 and beta adrenergic, cholinergic, dopaminergic, histaminergic, serotonergic and opioid receptor antagonists did not prevent the clonidine-induced emesis. The emesis induced by oxymetazoline, tramazoline, xylazine, naphazoline and epinephrine was also antagonized by a selective alpha-2 adrenoceptor antagonist, yohimbine, but not by a selective alpha-1 adrenoceptor antagonist, prazosin. In contrast, methoxamine and phenylephrine-induced emesis was antagonized by prazosin, but not by yohimbine. Neither yohimbine nor prazosin prevented the morphine- and histamine-induced emesis. These results indicate that alpha-2 adrenoceptors are involved in the mediation of emetic action, and that the alpha adrenoceptor-mediated emesis does not involve beta adrenergic, cholinergic, dopaminergic, histaminergic, serotonergic and opioid receptors in the emetic pathway. This study further suggests that alpha adrenoceptors involved in the emesis are mainly of the alpha-2 type, although the involvement of alpha-1 adrenoceptors cannot be ruled out. PMID:1349647

    2013-12-01

    Science/Technology/Society (STS) as a reform effort has been active in Iowa for three decades. A program called Iowa Chautauqua has evolved over the four decades to promote K-12 STS teaching in Iowa's 300 school districts. This is a study of how teachers have become Teacher Leaders of the reforms and lead other teachers who enroll as new teachers and schools each New Year. All were involved with Action Research projects each year while also assisting graduate student teams who serve as research associates. In this study, students were asked to identify specific teacher actions that were designed to make student learning more successful. The study examines general student views of teacher actions as well as specific examples of how students interact with the teacher and how the teachers encourage greater student/student involvement. The results show success with STS and how it defines science and affective actions of teachers in classrooms. Student views of Teacher Leaders, new Chautauqua teachers, and Control Teachers with no STS or Chautauqua experiences provide ways of recognizing successes of current reform efforts.

    NASA Astrophysics Data System (ADS)

    Cavicchi, Elizabeth Mary

    2008-08-01

    Two students, meeting together with a teacher, redid historical experiments. Unlike conventional instruction where science topics and practices often fragment, they experienced interrelatedness among phenomena, participants’ actions, and history. This study narrates actions that fostered an interrelated view. One action involved opening up historical telephones to examine interior circuitry. Another made sound visible in a transparent air column filled with Styrofoam bits and through Lissajous figures produced by reflecting light off orthogonal nineteenth century tuning forks crafted by Koenig and Kohl. Another involved orienting magnetic compasses to reveal the magnetism of conducting wires, historically investigated by Oersted and Schweigger. Replicating Homberg’s triboluminescent compound elicited students’ reflective awareness of history. These actions bore pedagogical value in recovering some of the interrelatedness inherent in the history and reintroducing the wonder of science phenomena to students today.

  9. Antithrombotic actions of statins involve PECAM-1 signaling.

    PubMed

    Moraes, Leonardo A; Vaiyapuri, Sakthivel; Sasikumar, Parvathy; Ali, Marfoua S; Kriek, Neline; Sage, Tanya; Gibbins, Jonathan M

    2013-10-31

    Statins are widely prescribed cholesterol-lowering drugs that are a first-line treatment of coronary artery disease and atherosclerosis, reducing the incidence of thrombotic events such as myocardial infarction and stroke. Statins have been shown to reduce platelet activation, although the mechanism(s) through which this occurs is unclear. Because several of the characteristic effects of statins on platelets are shared with those elicited by the inhibitory platelet adhesion receptor PECAM-1 (platelet endothelial cell adhesion molecule-1), we investigated a potential connection between the influence of statins on platelet function and PECAM-1 signaling. Statins were found to inhibit a range of platelet functional responses and thrombus formation in vitro and in vivo. Notably, these effects of statins on platelet function in vitro and in vivo were diminished in PECAM-1(-/-) platelets. Activation of PECAM-1 signaling results in its tyrosine phosphorylation, the recruitment and activation of tyrosine phosphatase SHP-2, the subsequent binding of phosphoinositol 3-kinase (PI3K), and diminished PI3K signaling. Statins resulted in the stimulation of these events, leading to the inhibition of Akt activation. Together, these data provide evidence for a fundamental role of PECAM-1 in the inhibitory effects of statins on platelet activation, which may explain some of the pleiotropic actions of these drugs. PMID:24030383

Because several of the characteristic effects of statins on platelets are shared with those elicited by the inhibitory platelet adhesion receptor PECAM-1 (platelet endothelial cell adhesion molecule-1), we investigated a potential connection between the influence of statins on platelet function and PECAM-1 signaling. Statins were found to inhibit a range of platelet functional responses and thrombus formation in vitro and in vivo. Notably, these effects of statins on platelet function in vitro and in vivo were diminished in PECAM-1−/− platelets. Activation of PECAM-1 signaling results in its tyrosine phosphorylation, the recruitment and activation of tyrosine phosphatase SHP-2, the subsequent binding of phosphoinositol 3-kinase (PI3K), and diminished PI3K signaling. Statins resulted in the stimulation of these events, leading to the inhibition of Akt activation. Together, these data provide evidence for a fundamental role of PECAM-1 in the inhibitory effects of statins on platelet activation, which may explain some of the pleiotropic actions of these drugs.

  4. When does action comprehension need motor involvement? Evidence from upper limb aplasia.

    PubMed

    Vannuscorps, Gilles; Andres, Michael; Pillon, Agnesa

    2013-01-01

    Motor theories of action comprehension claim that comprehending the meaning of an action performed by a conspecific relies on the perceiver's own motor representation of the same action. According to this view, whether an action belongs to the motor repertoire of the perceiver should impact the ease by which this action is comprehended. We tested this prediction by assessing the ability of an individual (D.C.) born without upper limbs to comprehend actions involving hands (e.g., throwing) or other body parts (e.g., jumping). The tests used a range of different visual stimuli differing in the kind of information provided. The results showed that D.C. was as accurate and fast as control participants in comprehending natural video and photographic presentations of both manual and nonmanual actions, as well as pantomimes. However, he was selectively impaired at identifying point-light animations of manual actions. This impairment was not due to a difficulty in processing kinematic information per se. D.C. was indeed as accurate as control participants in two additional tests requiring a fine-grained analysis of an actor's arm or whole-body movements. These results challenge motor theories of action comprehension by showing that the visual analysis of body shape and motion provides sufficient input for comprehending observed actions. However, when body shape information is sparsely available, motor involvement becomes critical to interpret observed actions. We suggest that, with natural human movement stimuli, motor representations contribute to action comprehension each time visual information is incomplete or ambiguous. PMID:24215324

    This work arises from the need to investigate the role of motivational variables in homework involvement and academic achievement of elementary school students. The aims of this study are twofold: identifying the different combinations of student academic goals and analyzing the differences in homework involvement and academic achievement. The sample was composed of 535 fourth-, fifth- and sixth-grade elementary school students, between the ages of 9 and 13 years old. Findings showed three groups with different motivational profiles: a group of students with high multiple goals, another group with a learning goal orientation and a third group defined by a low multiple goals profile. Focusing on the differences between groups, it was observed that the amount of time doing homework was not associated with any motivational profile. Nevertheless, the differences were statistically significant between the motivational groups in the amount of homework (F(2, 530) = 42.59; p < .001; ηp 2 = .138), in the management of time spent on homework (F(2, 530) = 33.08; p < .001; ηp 2 = .111), and in academic achievement (F(2, 530) = 33.99; p < .001; ηp 2 = .114). The effect size was large for the amount of homework performed and was also relatively large in the case of management of time and academic achievement. PMID:26502792

    Soil genesis is a subject taught to students of Agrarian Sciences and Geography at the Federal University of Viçosa in Minas Gerais, Brazil. Each semester 200 to 250 students inscribe for it. It is organized as the first 60 hours course on soils for 1st and 2nd year's students. The course has a distinct pedagogical approach, which is based on Paulo Freire's education principles, known as socio constructivism. In such approach, learning environments and materials are prepared to stimulate dialogues and exchange of knowledge between students themselves, strengthening that their role is crucial to their own learning. During the course, students have different types of practical classes: indoors, in a class room or at the Earth Sciences museum and outdoors, in the field. In the class room they have the opportunity to handle materials -minerals, rocks, soils and maps-, follow demonstrations and perform small experiments. The classes given in the museum intend a broadening of the subjects approached in theoretical and practical classes. In the field classes the students are organized in small groups with the task to investigate soil formation by observation and description of geology, landscape, land use, soil expositions and some of the soil properties. Attracting students to soils involves looking at meanings and perceptions related to soils they bring with themselves and follow this up to sensitize and create awareness about their importance. With this aim, it is also included, as part of the evaluation, a final voluntary presentation that many of the students do. The presentation can be a song, a poem, a sketch or whatever they propose and create. Many of the presentations bring topics related to the new perception about soils they get during the semester and to ideas or questions raised in the field classes. A survey with the students showed that field classes are by far the preferred classes and they are considered more dynamic. Since students have less and less

    This study addressed a prevalence of low achievement in science courses in an urban school district in Georgia. National leaders and educators have identified the improvement of science proficiency as critical to the future of American industry. The purpose of this study was to examine parent involvement in this school district and its contribution to the academic achievement of successful science students. Social capital theory guided this study by suggesting that students achieve best when investments are made into their academic and social development. A collective case study qualitative research design was used to interview 9 parent participants at 2 elementary schools whose children scored in the exceeds category on the Science CRCT. The research questions focused on what these parents did at home to support their children's academic achievement. Data were collected using a semi-structured interview protocol and analyzed through the categorical aggregation of transcribed interviews. Key findings revealed that the parents invested time and resources in 3 practices: communicating high expectations, supporting and developing key skills, and communicating with teachers. These findings contribute to social change at both the local and community level by creating a starting point for teachers, principals, and district leaders to reexamine the value of parent input in the educational process, and by providing data to support the revision of current parent involvement policies. Possibilities for further study building upon the findings of this study may focus on student perceptions of their parents' parenting as it relates to their science achievement.

  10. Comparative investigations of manual action representations: evidence that chimpanzees represent the costs of potential future actions involving tools

    PubMed Central

    Frey, Scott H.; Povinelli, Daniel J.

    2012-01-01

    The ability to adjust one's ongoing actions in the anticipation of forthcoming task demands is considered as strong evidence for the existence of internal action representations. Studies of action selection in tool use reveal that the behaviours that we choose in the present moment differ depending on what we intend to do next. Further, they point to a specialized role for mechanisms within the human cerebellum and dominant left cerebral hemisphere in representing the likely sensory costs of intended future actions. Recently, the question of whether similar mechanisms exist in other primates has received growing, but still limited, attention. Here, we present data that bear on this issue from a species that is a natural user of tools, our nearest living relative, the chimpanzee. In experiment 1, a subset of chimpanzees showed a non-significant tendency for their grip preferences to be affected by anticipation of the demands associated with bringing a tool's baited end to their mouths. In experiment 2, chimpanzees' initial grip preferences were consistently affected by anticipation of the forthcoming movements in a task that involves using a tool to extract a food reward. The partial discrepancy between the results of these two studies is attributed to the ability to accurately represent differences between the motor costs associated with executing the two response alternatives available within each task. These findings suggest that chimpanzees are capable of accurately representing the costs of intended future actions, and using those predictions to select movements in the present even in the context of externally directed tool use.

  12. Involving service users in the classroom with social work students.

    Mackay, Rob; Millar, Jeremy

    2012-02-01

    The purpose of this paper is to explore and discuss issues related to the requirement by the Scottish Social Services Council (SSSC) and the Scottish Government that service users and carers are partners and stakeholders in social work education. This requirement is one of several that are used by the SSSC in the approval of Scottish Universities to deliver social work courses. This paper explains the developmental process of involving service users and carers as partners in the planning of social work courses at the Robert Gordon University (RGU), Aberdeen. This is illustrated with reference to a group made up of young people ('The Voice of Reason') and also in relation to a group made up of adult service users (the Service User Panel). This short paper suggests there are benefits for student learning if we invite service users and carers to become partners in the teaching/learning process. There are also benefits for teaching staff and indeed for the University itself as a public institution on the basis that an ongoing relationship allows for good partnership working. This enables the University and its staff to be viewed positively and from that vantage point further developments are more likely. At the same time this paper has discussed the need to avoid tokenistic moves through ensuring a sound organisational commitment is made to providing effective support and putting in place enabling structures and processes. Lastly it discusses the broader implications for partnership working in relation to the education and training of students for professional practice. The suggestion is made that such a teaching and learning approach equips the students with good partnership skills and attitudes that will help to inform their practice post-qualification. Interest is expressed in the experiences of other professions who have adopted similar approaches to incorporating service users into students' learning experiences. PMID:22035881

  13. Imitation and observational learning of hand actions: prefrontal involvement and connectivity.

    PubMed

    2012-01-16

    The first aim of this event-related fMRI study was to identify the neural circuits involved in imitation learning. We used a rapid imitation task where participants directly imitated pictures of guitar chords. The results provide clear evidence for the involvement of dorsolateral prefrontal cortex, as well as the fronto-parietal mirror circuit (FPMC) during action imitation when the requirements for working memory are low. Connectivity analyses further indicated a robust connectivity between left prefrontal cortex and the components of the FPMC bilaterally. We conclude that a mechanism of automatic perception-action matching alone is insufficient to account for imitation learning. Rather, the motor representation of an observed, complex action, as provided by the FPMC, only serves as the 'raw material' for higher-order supervisory and monitoring operations associated with the prefrontal cortex. The second aim of this study was to assess whether these neural circuits are also recruited during observational practice (OP, without motor execution), or only during physical practice (PP). Whereas prefrontal cortex was not consistently activated in action observation across all participants, prefrontal activation intensities did predict the behavioural practice effects, thus indicating a crucial role of prefrontal cortex also in OP. In addition, whilst OP and PP produced similar activation intensities in the FPMC when assessed during action observation, during imitative execution, the practice-related activation decreases were significantly more pronounced for PP than for OP. This dissociation indicates a lack of execution-related resources in observationally practised actions. More specifically, we found neural efficiency effects in the right motor cingulate-basal ganglia circuit and the FPMC that were only observed after PP but not after OP. Finally, we confirmed that practice generally induced activation decreases in the FPMC during both action observation and

    2015-01-01

    The concept of hierarchical motor control has been viewed as a means of progressively decreasing the number of variables manipulated by each higher control level. We tested the hypothesis that turning an individual bimanual force-production task into a joint (two-participant) force-production task would lead to positive correlation between forces produced by the two hands of the individual participant (symmetric strategy) to enable negative correlation between forces produced by two participants (complementary strategy). The present study consisted of individual and joint tasks that involved both unimanual and bimanual conditions. In the joint task, 10 pairs of participants produced periodic isometric forces, such that the sum of forces that they produced matched a target force cycling between 5% and 10% of maximum voluntary contraction at 1 Hz. In the individual task, individuals attempted to match the same target force. In the joint bimanual condition, the two hands of each participant adopted a symmetric strategy of force, whereas the two participants adopted a complementary strategy of force, highlighting that the bimanual action behaved as a low level of a hierarchy, whereas the joint action behaved as an upper level. The complementary force production was greater interpersonally than intrapersonally. However, whereas the coherence was highest at 1 Hz in all conditions, the frequency synchrony was stronger intrapersonally than interpersonally. Moreover, whereas the bimanual action exhibited a smaller error and variability of force than the unimanual action, the joint action exhibited a less-variable interval and force than the individual action.

    Current theoretical positions assume that action-related word meanings are established by functional connections between perisylvian language areas and the motor cortex (MC) according to Hebb's associative learning principle. To test this assumption, we probed the functional relevance of the left MC for learning of a novel action word vocabulary by disturbing neural plasticity in the MC with transcranial direct current stimulation (tDCS). In combination with tDCS, subjects learned a novel vocabulary of 76 concrete, body-related actions by means of an associative learning paradigm. Compared with a control condition with "sham" stimulation, cathodal tDCS reduced success rates in vocabulary acquisition, as shown by tests of novel action word translation into the native language. The analysis of learning behavior revealed a specific effect of cathodal tDCS on the ability to associatively couple actions with novel words. In contrast, we did not find these effects in control experiments, when tDCS was applied to the prefrontal cortex or when subjects learned object-related words. The present study lends direct evidence to the proposition that the left MC is causally involved in the acquisition of novel action-related words. PMID:20888226

  18. Anxiolytic action of neuromedin-U and neurotransmitters involved in mice.

    PubMed

    Telegdy, G; Adamik, A

    2013-09-10

    Peptide Neuromedin-U (NmU) is widely distributed in the central nervous system and the peripheral tissues. Its physiological effects include the regulation of blood pressure, heart rate, and body temperature, and the inhibition of gastric acid secretion. The action of NmU in rats is mediated by two G-protein-coupled receptors, NmU-1R and NmU-2R. NmU-2R is present mainly in the brain, and NmU-1R mainly in the periphery. Despite the great variety of the physiological action of NmU, little is known about its possible effects in different forms of behavior, such as anxiety. In the present work, NmU-23 (the rodent form of the peptide) was tested for its effect on anxiety in elevated plus maze test in mice. For detection of the possible involvement of neurotransmitters, the mice were pretreated with receptor blockers: haloperidol (a D2, dopamine receptor antagonist), propranolol (a β-adrenergic receptor antagonist), atropine (a nonselective muscarinic acetylcholine receptor antagonist), phenoxybenzamine (a nonselective α-adrenergic receptor antagonist) or nitro-l-arginine (a nitric oxide synthase inhibitor). The peptide and nitro-l-arginine were administered into the lateral brain ventricle, while the receptor blockers were applied intraperitoneally. An NmU-23 dose 0.5μg elicited anxiolytic action, whereas this action is faded away when the dose was increased. For further testing therefore 0.5μg i.c.v. was used. Propranolol and atropine fully blocked the NmU-induced anxiolytic action, while haloperidol, phenoxybenzamine and nitro-l-arginine were ineffective. The results suggest that β-adrenergic and cholinergic mechanisms are involved in the anxiolytic action of NmU. PMID:23892031

    Mitragynine is a major alkaloidal constituent extracted from the young leaves of Mitragyna speciosa Korth. (Rubiaceae). We investigated an antinociceptive activity of intraperitoneal (i.p.) and intracerebroventricular (i.c.v.) injection of this alkaloid by the tail-pinch and hot-plate tests in mice, and evaluated the mechanisms of the action using naloxone, an opioid receptor antagonist. Mitragynine (5.0-30 mg/kg, i.p. and 1.0-10 micrograms/mouse, i.c.v.) exerted a dose-dependent antinociceptive activity which was maximal at 15-45 min after injection in the tail-pinch and hot-plate tests, but it did not induce a morphine-like behavioral change. the antinociceptive actions of i.p. mitragynine were completely abolished by both s.c. (2 mg/kg) and i.c.v (10 micrograms/mouse) naloxone. The action of i.c.v. mitragynine (10 micrograms/mouse) was also antagonized by i.c.v. naloxone (10 micrograms/mouse). These results indicate that mitragynine itself can induce antinociception by acting in the brain, and that the supraspinal opioid systems are at least partly involved in the antinociceptive action of mitragynine in mice.

    Natural compounds have shown good potential for the discovery of new chemotherapeutics for the treatment of Chagas’ disease. Recently, our group reported the effective trypanocidal activity of (−)-elatol, extracted from the red macroalgae Laurencia dendroidea present in the Brazilian coast against Trypanosoma cruzi. However, the mechanism of action of this compound has remained unclear. There are only hypotheses concerning its action on mitochondrial function. Here, we further investigated the mechanisms of action of (−)-elatol on trypomastigotes of T. cruzi. For this, we evaluated some biochemical alterations in trypomastigotes treated with (−)-elatol. Our results show that (−)-elatol induced depolarization of the mitochondrial membrane, an increase in the formation of mitochondrial superoxide anion and loss of cell membrane and DNA integrity. Additionally, (−)-elatol induced formation of autophagic vacuoles and a decrease in cell volume. All together, these results suggest that the trypanocidal action of (−)-elatol involves multiple events and mitochondria might be the initial target organelle. Our hypothesis is that the mitochondrial dysfunction leads to an increase of ROS production through the electron transport chain, which affects cell membrane and DNA integrity leading to different types of parasite death.

    HM-1 killer toxin secreted from Hansenula mrakii inhibits the growth of Saccharomyces cerevisiae cells by interfering with beta-1,3-glucan synthesis. We found that HM-1 killer toxin killed intact cells but not protoplasts. In addition, cells lacking the functional KRE6 allele (kre6 delta) became resistant to higher concentration of HM-1 killer toxin. As reported by Roemer and Bussey [(1991) Proc. Natl. Acad. Sci. 88 11295-11299], cells lacking functional KRE6 had a reduced level of the cell wall beta-1,6-glucan compared to that in cells harboring the normal KRE6. These results suggest that the cell wall beta-glucan is involved in the action of HM-1 killer toxin. Addition of HM-1 killer toxin with several kinds of oligosaccharides revealed that either beta-1,3- or beta-1,6-glucan blocked the cytocidal action of HM-1 killer toxin whereas alpha-1,4-glucan and chitin did not. Mannan also interfered with HM-1 killer toxin action, but this inhibitory effect was much weaker than that observed with beta-1,3- or beta-1,6-glucans. Thus, it appears that the cell wall beta-glucan interacts with HM-1 killer toxin, and that this toxin-beta-glucan commitment is required for the action of HM-1 killer toxin. PMID:8026578

    The alcoholic leaf extract of Ocimum sanctum (OS, Tulsi) was tested for analgesic activity in mice. In the glacial acetic acid (GAA)-induced writhing test, OS (50, 100 mg/kg, i.p.; and 50, 100, 200 mg/kg, p.o.) reduced the number of writhes. OS (50, 100 mg/kg, i.p.) also increased the tail withdrawal latency in mice. Naloxone (1 mg/kg, i.p.), an opioid antagonist, and DSP-4 (50 mg/kg, i.p.), a central noradrenaline depletor, attenuated the analgesic effect of OS in both the experimental models, whereas, PCPA (300 mg/kg, i.p.), a serotonin synthesis inhibitor, potentiated the action of OS on tail flick response in mice. The results of our study suggest that the analgesic action of OS is exerted both centrally as well as peripherally and involves an interplay between various neurotransmitter systems. PMID:12963158

    Propolis is a beehive product used in traditional medicine due to its biological properties. It shows a complex chemical composition including phenolics, such as cinnamic acid (Ci). The mechanisms of action of propolis have been the subject of research recently; however, the involvement of Ci on propolis activity was not investigated on immune cells. Ci effects were evaluated on human monocytes, assessing the expression of Toll-like receptors (TLRs), HLA-DR, and CD80. Cytokine production (TNF-α and IL-10) and the fungicidal activity of monocytes were evaluated as well. Data showed that Ci downregulated TLR-2, HLA-DR, and CD80 and upregulated TLR-4 expression by human monocytes. High concentrations of Ci inhibited both TNF-α and IL-10 production, whereas the same concentrations induced a higher fungicidal activity against Candida albicans. TNF-α and IL-10 production was decreased by blocking TLR-4, while the fungicidal activity of monocytes was not affected by blocking TLRs. These results suggest that Ci modulated antigen receptors, cytokine production, and the fungicidal activity of human monocytes depending on concentration, and TLR-4 may be involved in its mechanism of action. Ci seemed to be partially involved in propolis activities. PMID:23762102

    2015-06-01

    Psychostimulants are highly effective in the treatment of attention-deficit/hyperactivity disorder. The clinical efficacy of these drugs is strongly linked to their ability to improve cognition dependent on the prefrontal cortex (PFC) and extended frontostriatal circuit. The procognitive actions of psychostimulants are only associated with low doses. Surprisingly, despite nearly 80 years of clinical use, the neurobiology of the procognitive actions of psychostimulants has only recently been systematically investigated. Findings from this research unambiguously demonstrate that the cognition-enhancing effects of psychostimulants involve the preferential elevation of catecholamines in the PFC and the subsequent activation of norepinephrine α2 and dopamine D1 receptors. In contrast, while the striatum is a critical participant in PFC-dependent cognition, where examined, psychostimulant action within the striatum is not sufficient to enhance cognition. At doses that moderately exceed the clinical range, psychostimulants appear to improve PFC-dependent attentional processes at the expense of other PFC-dependent processes (e.g., working memory, response inhibition). This differential modulation of PFC-dependent processes across dose appears to be associated with the differential involvement of noradrenergic α2 versus α1 receptors. Collectively, this evidence indicates that at low, clinically relevant doses, psychostimulants are devoid of the behavioral and neurochemical actions that define this class of drugs and instead act largely as cognitive enhancers (improving PFC-dependent function). This information has potentially important clinical implications as well as relevance for public health policy regarding the widespread clinical use of psychostimulants and for the development of novel pharmacologic treatments for attention-deficit/hyperactivity disorder and other conditions associated with PFC dysregulation.

    2007-01-01

    Background Participation by communities in improving the quality of health services has become a feature of government policy in the United Kingdom. The aim of the study was to involve a deprived community in the UK in shaping quality improvements of local primary care services. The specific objectives were firstly to create participation by local people in evaluating the primary care services available in the area and secondly to bring about change as a result of this process. Methods The methods of participatory action research was used. The study was set in an area of high socio-economic deprivation served by a 'Local Health Care Co-operative' in a peripheral housing estate in Glasgow, Scotland. 72 local residents took part in 11 focus groups: eight of these were with community groups and three with other residents. 372 local residents completed questionnaires either by brief face-to-face interviews (114) or by self or carer completion (258). Results The study group produced recommendations on physical access to the health centre, time constraints in accessing services and problems encountered in individual relationships with health staff. They also highlighted the social gap between health service providers and the daily life of community residents. Action was taken to bring these recommendations to the attention of the Primary Care Organisation. Conclusion Participatory action research was used to involve a deprived community in the UK in a 'bottom-up' approach aimed at improving quality of local primary care services. Although successful in creating a partnership between academic researchers and lay researchers and participation by local people in evaluating the primary care services available in the area, the impact of the study in terms of immediate action taken over specific issues has been modest. The possible reasons for this are discussed. PMID:17572913

    The Pulsar Search Collaboratory (PSC) is an NSF funded ITEST program that engages high school students and their teachers in radio astronomy research. Teachers and students from 72 schools have received training through this program. More than 300 students have joined with astronomers in analyzing data, and several discoveries have been made. In this paper we examine the evaluation data collected to determine if initial goals were met, and if in fact, the initial goals were the right ones. In particular we examine whether participation in the PSC a) affected students' and teachers' understanding of the nature of scientific inquiry, and b) motivated students to pursue STEM career paths.

    Jensen, Bjarne Bruun; Simovska, Venka

    2005-01-01

    The concept of student participation is currently a popular notion in health promoting schools as well as in general education. However, phrases such as 'involvement', 'participation', 'co-determination' and 'influence' are frequently used without careful definition. In this article two models, developed in the context of health promoting schools in two different cultures, are presented and discussed. The first model makes a fundamental distinction between token and genuine participation. Token participation in health promotion is characterised by focusing on prescribed knowledge, closed and convergent outcomes and targeting individuals isolated from the surrounding environment. In contrast, genuine participation stresses students' own construction of knowledge, open and divergent outcomes and targeting individuals in their context. Genuine participation is in accordance with a democratic health promoting school aiming at students' empowerment and action competence. The second model clarifies a number of different categories of students' participation in health promotion. The different categories illustrate how the teacher in various ways can play an active role in participatory approaches as a responsible professional. The more the students are involved in health projects, the more important it will be for the teacher to provide support, insight and knowledge to facilitate the learning processes. Furthermore, the different participation categories have to be related to a number of decisions which are normally included in a school health project. The model illustrates that participation should always be viewed in relation to the context and that it makes no sense to establish a single ideal way of working with participation in a health promoting school. The theoretical models are illuminated by concrete examples from health promoting schools. The overall conclusion is that participation is a complex term and rather than providing definitive answers, the models can

    2000-11-01

    Interleukin-1beta (IL-1beta) participates in neuroinflammation and neurodegeneration. Its mechanisms of action are not fully understood, but appear to involve complex interactions between neurons and glia. The objective of this study was to determine the involvement of endogenous IL-1beta in inflammatory responses to LPS in cultured mouse glial cells, and compare this to the effects of exogenous IL-1beta. Activation of primary mixed glial cultures by incubation with LPS (1 microgram/ml, 24 h), caused marked (approximately ten-fold) increases in release of NO, twenty-fold increases in PGE(2) and ninety-fold increases of IL-6 release. Incubation with human recombinant IL-1beta (100 ng/ml) also stimulated NO and IL-6 release to a similar extent to LPS, but IL-1beta (1 or 100 ng/ml) caused only modest increases (approximately seven-fold) in PGE(2) release. Co-incubation with IL-1ra inhibited the effects of LPS on NO release (-65%) and IL-6 production (-30%), but failed to reduce PGE(2) release. These results indicate that exogenous IL-1beta induces release of NO, PGE(2) and IL-6 in mixed glial cultures, and that endogenous IL-1beta mediates inflammatory actions of LPS on NO and to a lesser extent IL-6, but not on PGE(2) release in mixed glial cultures. Indeed endogenous IL-1beta appears to inhibit LPS-induced PGE(2) release. PMID:11063815

    2016-01-01

    Neuropeptide AF (NPAF) is an amidated octadecapeptide, which is member of the RFamide peptide family. NPAF is encoded by the farp-1 gene and acts through the G protein coupled NPFF-1 and NPFF-2 receptors. NPAF is involved in several physiological functions of the central nervous system, however we have little evidence about the involvement of NPAF in learning and memory. Therefore, the aim of the present study was to investigate the action of NPAF on consolidation of memory in a passive avoidance learning paradigm in mice. We have also investigated the underlying neurotransmissions and the action of NPAF on β-amyloid-induced memory impairment. Accordingly, mice were pretreated with a nonselective muscarinic acetylcholine receptor antagonist, atropine, a non-selective 5-HT2 serotonergic receptor antagonist, cyproheptadine, a mixed 5-HT1/5-HT2 serotonergic receptor antagonist, methysergide, a D2, D3, D4 dopamine receptor antagonist, haloperidol, a non-selective opioid receptor antagonist, naloxone, a nitric oxide synthase inhibitor, nitro-l-arginine, a α1/α2β-adrenergic receptor antagonist, prazosin, a nonselective β-adrenergic receptor antagonist, propranolol or β-amyloid 25-35 in combination with NPAF administration. Our results demonstrate for the first time that NPAF improves the consolidation of passive avoidance learning. This effect is mediated through muscarinic cholinergic, 5HT1- and 5HT2-serotoninergic, dopaminergic, nitrergic and α- and β-adrenergic neurotransmissions, but not by opioid transmission, since atropine, cyproheptadine, methysergide, haloperidol, nitro-l-arginine, prazosin and propranolol reversed the action of NPAF, whereas naloxone was ineffective. The present study also shows that NPAF reverses the β-amyloid 25-35-induced memory impairment. PMID:26639667

  18. Suppression of cell membrane permeability by suramin: involvement of its inhibitory actions on connexin 43 hemichannels

    PubMed Central

    2014-01-01

    BACKGROUND AND PURPOSE Suramin is a clinically prescribed drug for treatment of human African trypanosomiasis, cancer and infection. It is also a well-known pharmacological antagonist of P2 purinoceptors. Despite its clinical use and use in research, the biological actions of this molecule are still incompletely understood. Here, we investigated the effects of suramin on membrane channels, as exemplified by its actions on non-junctional connexin43 (Cx43) hemichannels, pore-forming α-haemolysin and channels involved in ATP release under hypotonic conditions. EXPERIMENTAL APPROACH Hemichannels were activated by removing extracellular Ca2+. The influences of suramin on hemichannel activities were evaluated by its effects on influx of fluorescent dyes and efflux of ATP. The membrane permeability and integrity were assessed through cellular retention of preloaded calcein and LDH release. KEY RESULTS Suramin blocked Cx43 hemichannel permeability induced by removal of extracellular Ca2+ without much effect on Cx43 expression and gap junctional intercellular communication. This action of suramin was mimicked by its analogue NF023 and NF449 but not by another P2 purinoceptor antagonist PPADS. Besides hemichannels, suramin also significantly blocked intracellular and extracellular exchanges of small molecules caused by α-haemolysin from Staphylococcus aureus and by exposure of cells to hypotonic solution. Furthermore, it prevented α-haemolysin- and hypotonic stress-elicited cell injury. CONCLUSION AND IMPLICATIONS Suramin blocked membrane channels and protected cells against toxin- and hypotonic stress-elicited injury. Our finding provides novel mechanistic insights into the pharmacological actions of suramin. Suramin might be therapeutically exploited to protect membrane integrity under certain pathological situations. PMID:24641330

    Phenology plays a key role in the environment and ecosystem. Primary and secondary students around the world have been collecting vegetation phenology data and contributing to ongoing scientific investigations. They have increased research capacity by increasing spatial coverage of ground observations that can be useful for validation of remotely sensed data. The green-up and green-down phenology measurement protocols developed at the University of Alaska Fairbanks (UAF) as part of the Global Learning and Observations to Benefit the Environment (GLOBE) program, have been used in more than 250 schools in over 20 countries. In addition to contributing their data, students have conducted their own investigations and presented them at science fairs and symposiums, and international conferences. An elementary school student in Alaska conducted a comprehensive study on the green-down rates of native and introduced trees and shrubs. Her project earned her a one-year college scholarship at UAF. Students from the Model Secondary School for the Deaf in Washington, D. C. and from the Indiana School for the Deaf collaborated on a comparative green-up study, and were chosen to present at an international conference where students from more than 20 countries participated. Similarly, students in Thailand presented at national conferences, their studies such as "The Relationship between Environmental Conditions and Green-down of Teak Trees (Tectona grandis L.)" at Roong Aroon School, Bangkok and "The Comparison of Budburst and Green-up of Leab Trees (Ficus infectoria Roxb.) at Rob Wiang and Mae Khao Tom Sub-district in Chiang Rai Province". Some challenges in engaging students in phenological studies include the mismatch in timing of the start and end of the plant growing season with that of the school year in northern latitudes and the need for scientists and teachers to work with students to ensure accurate measurements. However these are outweighed by benefits to the scientists

    Organizational structure, practice, and management have an enormous affect on the success of student-lead and student-involved instrument missions. Through its involvements with the student projects SME, SNOE and SDC, LASP has developed organizational approaches that provide high-quality for-flight hardware that employs a mix of professionals and students. Keys to the success of these programs include the following tenets: 1) the professional involvement needs to be well defined at the onset of the program; 2) the organizational structure needs to be clearly defined; 3) student expectations and learning outcomes should be predetermined; and 4) the scope of the project needs to incorporate the time constraints of student availability so that outcomes allow students to experience project success (or project milestones) prior to graduation.

  9. The enzymatic hydrolysis of pretreated pulp fibers predominantly involves “peeling/erosion” modes of action

    PubMed Central

    2014-01-01

    Background There is still considerable debate regarding the actual mechanism by which a “cellulase mixture” deconstructs cellulosic materials, with accessibility to the substrate at the microscopic level being one of the major restrictions that limits fast, complete cellulose hydrolysis. In the work reported here we tried to determine the predominant mode of action, at the fiber level, of how a cellulase mixture deconstructs pretreated softwood and hardwood pulp fibers. Quantitative changes in the pulp fibers derived from different pretreated biomass substrates were monitored throughout the course of enzymatic hydrolysis to see if the dominant mechanisms involved either the fragmentation/cutting of longer fibers to shorter fibers or their “peeling/delamination/erosion,” or if both cutting and peeling mechanisms occurred simultaneously. Results Regardless of the source of biomass, the type of pretreatment and the chemical composition of the substrate, under typical hydrolysis conditions (50°C, pH 4.8, mixing) longer pulp fibers (fiber length >200 μm) were rapidly broken down until a relatively constant fiber length of 130 to 160 μm was reached. In contrast, shorter fibers with an initial average fiber length of 130 to 160 μm showed no significant change in length despite their substantial hydrolysis. The fragmentation/cutting mode of deconstruction was only observed on longer fibers at early stages of hydrolysis. Although the fiber fragmentation mode of deconstruction was not greatly influenced by enzyme loading, it was significantly inhibited by glucose and was mainly observed during initial mixing of the enzyme and substrate. In contrast, significant changes in the fiber width occurred throughout the course of hydrolysis for all of the substrates, suggesting that fiber width may limit the rate and extent of cellulose hydrolysis. Conclusion It appears that, at the fiber level, pretreated pulp fibers are hydrolyzed through a two-step mode of action

    2010-08-01

    This paper examines the mission, structure and outputs of one organisation, the Student Platform for Engineering Education Development (SPEED), as a case study for how student-led organisations can use student involvement to promote and sustain student self-efficacy in an academic field. SPEED attracts young people to engineering through student participation in engineering education (EE). SPEED is a global, non-profit student organisation that functions as an interdisciplinary network to diversify dialogue, stimulate change and impact the development of EE and its effect on society. SPEED is directly attracting young people to engineering in various ways: the organisation of its keynote event, the Global Student Forum; facilitating interactions between globally minded, socially inclined engineers with aspirations to change the world; and through the global dissemination of SPEED's work and practices through broad and relevant channels. Short-term outcomes are highlighted here. This case study can serve as a model for student engagement and involvement in other disciplines.

    1986-01-01

    The possible role of photosynthesis in the mechanism of action of the herbicide acifluorfen (2-chloro-4-(trifluoromethyl)phenoxy-2-nitrobenzoate; AF) was examined. The sensitivity to AF of cotyledons of cucumber (Cucumis sativus L.) which had been grown under far red light (FR) and white light were compared. FR grown tissues which were photosynthetically imcompetent were hypersensitive to AF under white light and had approximately the same relative response to AF under blue and red light as green, white-light-grown tissues. Ultrastructural damage was apparent in FR-grown, AF-treated tissues within an hour after exposure to white light, with cytoplasmic and plastidic disorganization occurring simultaneously. In cucumber cotyledon tissue which had been greening for various time periods, there was no correlation between photosynthetic capacity and herbicidal efficacy of AF. PSII inhibitors (atrazine and DCMU) and the photophosphorylation inhibitor, tentoxin, had no effect on AF activity. Atrazine did not reduce AF activity at any concentration or light intensity tested, indicating that there is no second, photosynthetic-dependent mechanism of action operating at low AF concentrations or low fluence rates. Carbon dioxide-dependent O2 evolution of intact chloroplasts of spinach (Spinacia oleracea L.) had an AF I50 of 125 micromolar compared to 1000 micromolar for cucumber, whereas AF was much more herbicidally active in tissues of cucumber than of spinach. Differences in activity could not be accounted for by differences in uptake of AF. Our results indicate that there is no photosynthetic involvement in the mechanism of action of AF in cucumber.

    2014-01-01

    Action potential (AP) generation is the key to information-processing in the brain. Although APs are normally initiated in the axonal initial segment, developmental adaptation or prolonged network activity may alter the initiation site geometry thus affecting cell excitability. Here we find that hippocampal dentate granule cells adapt their spiking threshold to the kinetics of the ongoing dendrosomatic excitatory input by expanding the AP-initiation area away from the soma while also decelerating local axonal spikes. Dual-patch soma-axon recordings combined with axonal Na(+) and Ca(2+) imaging and biophysical modelling show that the underlying mechanism involves distance-dependent inactivation of axonal Na(+) channels due to somatic depolarization propagating into the axon. Thus, the ensuing changes in the AP-initiation zone and local AP propagation could provide activity-dependent control of cell excitability and spiking on a relatively rapid timescale. PMID:24851940

  19. Epigenetic regulation of the expression of genes involved in steroid hormone biosynthesis and action

    PubMed Central

    Martinez-Arguelles, Daniel B.; Papadopoulos, Vassilios

    2010-01-01

    Steroid hormones participate in organ development, reproduction, body homeostasis, and stress responses. The steroid machinery is expressed in a development- and tissue-specific manner, with the expression of these factors being tightly regulated by an array of transcription factors (TFs). Epigenetics provides an additional layer of gene regulation through DNA methylation and histone tail modifications. Evidence of epigenetic regulation of key steroidogenic enzymes is increasing, though this does not seem to be a predominant regulatory pathway. Steroid hormones exert their action in target tissues through steroid nuclear receptors belonging to the NR3A and NR3C families. Nuclear receptor expression levels and post-translational modifications regulate their function and dictate their sensitivity to steroid ligands. Nuclear receptors and TFs are more likely to be epigenetically regulated than proteins involved in steroidogenesis and have secondary impact on the expression of these steroidogenic enzymes. Here we review evidence for epigenetic regulation of enzymes, transcription factors, and nuclear receptors related to steroid biogenesis and action. PMID:20156469

    2013-07-01

    Botulinum toxin A (BTX-A) is approved for treatment of chronic migraine and has been investigated in various other painful conditions. Recent evidence demonstrated retrograde axonal transport and suggested the involvement of CNS in antinociceptive effect of BTX-A. However, the mechanism of BTX-A central antinociceptive action is unknown. In this study we investigated the potential role of opioid receptors in BTX-A's antinociceptive activity. In formalin-induced inflammatory pain we assessed the effect of opioid antagonists on antinociceptive activity of BTX-A. Naltrexone was injected subcutaneously (0.02-2 mg/kg) or intrathecally (0.07 μg/10 μl-350 μg/10 μl), while selective μ-antagonist naloxonazine was administered intraperitoneally (5 mg/kg) prior to nociceptive testing. The influence of naltrexone (2 mg/kg s.c.) on BTX-A antinociceptive activity was examined additionally in an experimental neuropathy induced by partial sciatic nerve transection. To investigate the effects of naltrexone and BTX-A on neuronal activation in spinal cord, c-Fos expression was immunohistochemically examined in a model of formalin-induced pain. Antinociceptive effects of BTX-A in formalin and sciatic nerve transection-induced pain were prevented by non-selective opioid antagonist naltrexone. Similarly, BTX-A-induced pain reduction was abolished by low dose of intrathecal naltrexone and by selective μ-antagonist naloxonazine. BTX-A-induced decrease in dorsal horn c-Fos expression was prevented by naltrexone. Prevention of BTX-A effects on pain and c-Fos expression by opioid antagonists suggest that the central antinociceptive action of BTX-A might be associated with the activity of endogenous opioid system (involving μ-opioid receptor). These results provide first insights into the mechanism of BTX-A's central antinociceptive activity. PMID:23499661

  1. Neuroprotective action of cycloheximide involves induction of bcl-2 and antioxidant pathways.

    PubMed

    1997-03-10

    The ability of the protein synthesis inhibitor cycloheximide (CHX) to prevent neuronal death in different paradigms has been interpreted to indicate that the cell death process requires synthesis of "killer" proteins. On the other hand, data indicate that neurotrophic factors protect neurons in the same death paradigms by inducing expression of neuroprotective gene products. We now provide evidence that in embryonic rat hippocampal cell cultures, CHX protects neurons against oxidative insults by a mechanism involving induction of neuroprotective gene products including the antiapoptotic gene bcl-2 and antioxidant enzymes. Neuronal survival after exposure to glutamate, FeSO4, and amyloid beta-peptide was increased in cultures pretreated with CHX at concentrations of 50-500 nM; higher and lower concentrations were ineffective. Neuroprotective concentrations of CHX caused only a moderate (20-40%) reduction in overall protein synthesis, and induced an increase in c-fos, c-jun, and bcl-2 mRNAs and protein levels as determined by reverse transcription-PCR analysis and immunocytochemistry, respectively. At neuroprotective CHX concentrations, levels of c-fos heteronuclear RNA increased in parallel with c-fos mRNA, indicating that CHX acts by inducing transcription. Neuroprotective concentrations of CHX suppressed accumulation of H2O2 induced by FeSO4, suggesting activation of antioxidant pathways. Treatment of cultures with an antisense oligodeoxynucleotide directed against bcl-2 mRNA decreased Bcl-2 protein levels and significantly reduced the neuroprotective action of CHX, suggesting that induction of Bcl-2 expression was mechanistically involved in the neuroprotective actions of CHX. In addition, activity levels of the antioxidant enzymes Cu/Zn-superoxide dismutase, Mn-superoxide dismutase, and catalase were significantly increased in cultures exposed to neuroprotective levels of CHX. Our data suggest that low concentrations of CHX can promote neuron survival by

    Munk, Lyle Kris

    2016-01-01

    The primary emphasis in dental education is on developing students' cognitive intelligence (thinking) and technical intelligence (doing), while emotional intelligence (being) receives less emphasis. The aim of this study was to explore a potential consequence of the paucity of emotional intelligence education by determining the level of emotional intelligence-related (EI-R) infractions in state dental board disciplinary actions and characterizing the types of those infractions. For this study, 1,100 disciplinary action reports from 21 state dental boards were reviewed, and disciplinary infractions were classified as cognitive intelligence-related (CI-R) infractions, technical intelligence-related (TI-R) infractions, and EI-R infractions. EI-R infractions were then subcategorized into emotional intelligence clusters and competencies using the Emotional and Social Competency Inventory (ESCI). The results showed that 56.6% of the infractions were EI-R. When the EI-R infractions were subcategorized, the four competencies most frequently violated involved transparency, teamwork and collaboration, organizational awareness, and accurate self-assessment. Understanding the frequency and nature of EI-R infractions may promote awareness of the need for increased attention to principles of emotional intelligence in dental education and may encourage integration of those principles across dental curricula to help students understand the impact of emotional intelligence on their future well-being and livelihood.

    2016-08-01

    To identify novel genes that mediate cellular sensitivity and resistance to 5-fluorouracil (5-FU), we performed a genome-wide genetic screening to identify altered susceptibility to 5-FU by Schizosaccharomyces pombe haploid nonessential gene deletion library containing 3004 deletion mutants. We identified 50 hypersensitive and 12 resistant mutants to this drug. Mutants sensitive or resistant to 5-FU were classified into various categories based on their putative functions. The largest group of the genes whose disruption renders cells altered susceptibility to 5-FU is involved in nucleic acid metabolism, but to our surprise, the second largest group is involved in membrane trafficking. In addition, several other membrane traffic mutants examined including gdi1-i11, ypt3-i5, Δryh1, Δric1, and Δaps1 exhibited hypersensitivity to 5-FU. Furthermore, we found that 5-FU in low concentration that generally do not affect cell growth altered the localization of Syb1, a secretory vesicle SNARE synaptobrevin which is cycled between the plasma membrane and the endocytic pathway. Notably, 5-FU at such low concentration also significantly inhibited the secretion of acid phosphatase. Altogether, our findings revealed the first evidence that 5-FU influences membrane trafficking as the potential underlying mechanism of the drug action. PMID:27255861

  7. Involvement of the Motor System in Comprehension of Non-Literal Action Language: A Meta-Analysis Study.

    PubMed

    Yang, Jie; Shu, Hua

    2016-01-01

    Although numerous studies have shown that the sensory-motor system is involved in semantic processing of language stimuli, it is still unclear whether comprehension of abstract concepts is embodied, and whether the involvement of the sensory-motor system is context-dependent. Investigation of how the motor system is activated during comprehension of non-literal action languages can help address these issues. So far several studies have reported brain activations during non-literal action language comprehension, but the findings are highly inconsistent because of different types of non-literal action language stimuli. To clarify how the motor system is involved in comprehension of different types of non-literal languages, the current study conducted quantitative meta-analyses on fMRI findings about comprehension of sentences describing fictive motions, metaphoric actions, and idiomatic actions. Results showed that fictive motion sentences elicited activation in the right parahippocampal gyrus, an area important for spatial processing. For metaphoric actions, the left precentral gyrus (BA 6) was strongly activated, suggesting a link between metaphoric and literal meanings. For idiomatic actions, activity was found in the left inferior frontal gyrus (BA 44/45), highlighting semantic selection and inhibition. No premotor or motor activity was found in idiom condition. These results together suggest that the involvement of the sensory-motor system in abstract concepts processing is flexible, depending on semantic features of the language stimuli and links between abstract and literal meanings.

  19. Quantitative assessment of the distributions of membrane conductances involved in action potential backpropagation along basal dendrites.

    PubMed

    Acker, Corey D; Antic, Srdjan D

    2009-03-01

    Basal dendrites of prefrontal cortical neurons receive strong synaptic drive from recurrent excitatory synaptic inputs. Synaptic integration within basal dendrites is therefore likely to play an important role in cortical information processing. Both synaptic integration and synaptic plasticity depend crucially on dendritic membrane excitability and the backpropagation of action potentials. We carried out multisite voltage-sensitive dye imaging of membrane potential transients from thin basal branches of prefrontal cortical pyramidal neurons before and after application of channel blockers. We found that backpropagating action potentials (bAPs) are predominantly controlled by voltage-gated sodium and A-type potassium channels. In contrast, pharmacologically blocking the delayed rectifier potassium, voltage-gated calcium, or I(h) conductance had little effect on dendritic AP propagation. Optically recorded bAP waveforms were quantified and multicompartmental modeling was used to link the observed behavior with the underlying biophysical properties. The best-fit model included a nonuniform sodium channel distribution with decreasing conductance with distance from the soma, together with a nonuniform (increasing) A-type potassium conductance. AP amplitudes decline with distance in this model, but to a lesser extent than previously thought. We used this model to explore the mechanisms underlying two sets of published data involving high-frequency trains of APs and the local generation of sodium spikelets. We also explored the conditions under which I(A) down-regulation would produce branch strength potentiation in the proposed model. Finally, we discuss the hypothesis that a fraction of basal branches may have different membrane properties compared with sister branches in the same dendritic tree. PMID:19118105

  20. Potential involvement of serotonergic signaling in ketamine's antidepressant actions: A critical review.

    2016-11-01

    A single i.v. infusion of ketamine, classified as an N-methyl-d-aspartate (NMDA) receptor antagonist, may alleviate depressive symptoms within hours of administration in treatment resistant depressed patients, and the antidepressant effect may last for several weeks. These unique therapeutic properties have prompted researchers to explore the mechanisms mediating the antidepressant effects of ketamine, but despite many efforts, no consensus on its antidepressant mechanism of action has been reached. Recent preclinical reports have associated the neurotransmitter serotonin (5-hydroxytryptamine; 5-HT) with the antidepressant-like action of ketamine. Here, we review the current evidence for a serotonergic role in ketamine's antidepressant effects. The pharmacological profile of ketamine may include equipotent activity on several non-NMDA targets, and the current hypotheses for the mechanisms responsible for ketamine's antidepressant activity do not appear to preclude the possibility that non-glutamate neurotransmitters are involved in the antidepressant effects. At multiple levels, the serotonergic and glutamatergic systems interact, and such crosstalk could support the notion that changes in serotonergic neurotransmission may impact ketamine's antidepressant potential. In line with these prospects, ketamine may increase 5-HT levels in the prefrontal cortex of rats, plausibly via hippocampal NMDA receptor inhibition and activation of α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors. In addition, a number of preclinical studies suggest that the antidepressant-like effects of ketamine may depend on endogenous activation of 5-HT receptors. Recent imaging and behavioral data predominantly support a role for 5-HT1A or 5-HT1B receptors, but the full range of 5-HT receptors has currently not been systematically investigated in this context. Furthermore, the nature of any 5-HT dependent mechanism in ketamine's antidepressant effect is currently not

  3. Effect of scaffolding on helping introductory physics students solve quantitative problems involving strong alternative conceptions

    NASA Astrophysics Data System (ADS)

    Lin, Shih-Yin; Singh, Chandralekha

    2015-12-01

    It is well known that introductory physics students often have alternative conceptions that are inconsistent with established physical principles and concepts. Invoking alternative conceptions in the quantitative problem-solving process can derail the entire process. In order to help students solve quantitative problems involving strong alternative conceptions correctly, appropriate scaffolding support can be helpful. The goal of this study is to examine how different scaffolding supports involving analogical problem-solving influence introductory physics students' performance on a target quantitative problem in a situation where many students' solution process is derailed due to alternative conceptions. Three different scaffolding supports were designed and implemented in calculus-based and algebra-based introductory physics courses involving 410 students to evaluate the level of scaffolding needed to help students learn from an analogical problem that is similar in the underlying principles involved but for which the problem-solving process is not derailed by alternative conceptions. We found that for the quantitative problem involving strong alternative conceptions, simply guiding students to work through the solution of the analogical problem first was not enough to help most students discern the similarity between the two problems. However, if additional scaffolding supports that directly helped students examine and repair their knowledge elements involving alternative conceptions were provided, e.g., by guiding students to contemplate related issues and asking them to solve the targeted problem on their own first before learning from the analogical problem provided, students were more likely to discern the underlying similarities between the problems and avoid getting derailed by alternative conceptions when solving the targeted problem. We also found that some scaffolding supports were more effective in the calculus-based course than in the algebra

  4. Mediators involved in the hyperthermic action of neuromedin U in rats.

    PubMed

    Telegdy, G; Adamik, A

    2014-01-01

    Neuromedin U (NmU), first was isolated from the porcine spinal cord, has subsequently been demonstrated in a number of species, in which it is present in the periphery and also the brain. Two receptors have been identified: NmU1R is mainly present in peripheral tissues, and Nmu2R in the central nervous system. NmU, a potent endogenous anorectic, serves as a catabolic signaling molecule in the brain; it inhibits food uptake, increases locomotion, activates stress mechanism, having cardiovasscular effects and, causes hyperthermia. The mechanism of this hyperthermia is unknown. In the present experiments, the effects of NmU on the colon temperature following i.c.v administration were studied in rats. For an investigation of the possible role of receptors in mediating hyperthermia, the animals were treated simultaneously with CRF 9-41 and antalarmin, a CRH1 receptor inhibitors, astressin 2B, a CRH2 receptor antagonist, haloperidol a dopamine receptor antagonist, atropine a muscarinic cholinergic receptor antagonist, noraminophenazone a cyclooxygenase inhibitor or isatin, a prostaglandin receptor antagonist. NmU increased the colon temperature, maximal action being observed at 2-3h. CRF 9-41, antalarmin, astressin 2B haloperidol, atropine, noraminophenazone and isatin prevented the NmU-induced increase in colon temperature. The results demonstrated that, when injected into the lateral brain ventricle NmU increased the body temperature, mediated by CRHR1 and CRHR2, dopamine and muscarinic cholinergic receptors. The final pathway involves prostaglandin. PMID:25108055

  5. Involvement of the endogenous opioid system in the psychopharmacological actions of ethanol: the role of acetaldehyde

    Font, Laura; Luján, Miguel Á.; Pastor, Raúl

    2013-01-01

    Significant evidence implicates the endogenous opioid system (EOS) (opioid peptides and receptors) in the mechanisms underlying the psychopharmacological effects of ethanol. Ethanol modulates opioidergic signaling and function at different levels, including biosynthesis, release, and degradation of opioid peptides, as well as binding of endogenous ligands to opioid receptors. The role of β-endorphin and µ-opioid receptors (OR) have been suggested to be of particular importance in mediating some of the behavioral effects of ethanol, including psychomotor stimulation and sensitization, consumption and conditioned place preference (CPP). Ethanol increases the release of β-endorphin from the hypothalamic arcuate nucleus (NArc), which can modulate activity of other neurotransmitter systems such as mesolimbic dopamine (DA). The precise mechanism by which ethanol induces a release of β-endorphin, thereby inducing behavioral responses, remains to be elucidated. The present review summarizes accumulative data suggesting that the first metabolite of ethanol, the psychoactive compound acetaldehyde, could participate in such mechanism. Two lines of research involving acetaldehyde are reviewed: (1) implications of the formation of acetaldehyde in brain areas such as the NArc, with high expression of ethanol metabolizing enzymes and presence of cell bodies of endorphinic neurons and (2) the formation of condensation products between DA and acetaldehyde such as salsolinol, which exerts its actions via OR.

    2016-08-01

    Traffic noise is gaining importance in planning and operation of roads in developing countries, and particularly in Europe and Latin America. Many variables with different degrees of importance influence the perception of noise from roads. Thus, the problem of prioritizing road stretches for action against such noise is an important issue in environmental noise management. For example, it can be addressed using multicriteria methods. However, these methodologies require criteria or suitable variables to be ranked according to their relative importance. In the present study, for this ranking, a list of nine variables involved in the decision-making process (called "road stretch priority variables") was presented in the form of questionnaires to high-level experts from Andalusia, southern Spain. These experts ranked the variables by relevance. Using the same data, seven social choice functions (Plurality, Raynaud, Kemeny-Young, Copeland, Simpson, Schulze, and Borda) were used in order to rank the variables. The results indicate that the most important variables were those that take into account the parameters of greatest exposure for the citizens, followed by variables related to the intensity of the problem analyzed. The results show that a combination of the use of social choice functions on aggregated information from expert panels can provide a consensus for ranking priority variables related to road stretches.

  8. Commentary: medical student distress: a call to action.

    PubMed

    Dyrbye, Liselotte N; Shanafelt, Tait D

    2011-07-01

    Studies have found a high prevalence of psychological distress among medical students both in the United States and abroad. Distress among medical students has serious professional ramifications, including damaging effects on empathy, ethical conduct, and professionalism, as well as personal consequences such as substance abuse, broken relationships, and suicidal ideation. Given the effect of physician distress on quality of care, self-care (including personal appraisal of well-being, wellness promotion, and recognition of when help is needed) should be recognized as a core competency for physicians. In this issue of Academic Medicine, investigators at the Northwestern University Feinberg School of Medicine explore the benefits of teaching students to employ a cognitive behavioral approach to improving self-care. Beyond its demonstrated short-term efficacy, the approach they propose also has potential to help students develop the skills necessary to assess and promote resilience throughout their careers. Medical schools' responsibility to promote student wellness, however, goes beyond teaching students self-care skills and includes establishing an appropriate organizational culture and learning environment to promote student health. Achieving competency in self-care is a shared responsibility of the individual physician/resident/medical student and the organizational environment in which he or she functions. PMID:21715992

    Community colleges enroll more than half of the undergraduate population in the United States, thereby retaining students of varying demographics with extracurricular demands differing from traditional four-year university students. Often in a collegiate lecture course, students are limited in their abilities to absorb and process information presented by their instructors due to content-specific cognitive gaps between the instructor and the student (Preszler, 2009). Research has shown that implementation of instructor-facilitated action learning workshops as supplemental instruction may help bridge these cognitive gaps allowing better student conceptualization and dissemination of knowledge (Drake, 2011; Fullilove & Treisman, 1990; Preszler, 2009; Udovic, Morris, Dickman, Postlethwait, & Wetherwax, 2002). The purpose of this study was to determine the effects of cooperative action learning workshops and independent action learning workshops on students' knowledge of specified topics within a General Biology I with lab course. The results of this investigation indicate that implementation of an instructor-facilitated action learning workshop did not affect students' knowledge gain; furthermore, attendance of a particular workshop style (independent or cooperative) did not affect students' knowledge gain.

  1. The sequential encoding of competing action goals involves dynamic restructuring of motor plans in working memory.

    PubMed

    Gallivan, Jason P; Bowman, Natasha A R; Chapman, Craig S; Wolpert, Daniel M; Flanagan, J Randall

    2016-06-01

    Recent neural and behavioral findings provide support for the influential idea that in situations in which multiple action options are presented simultaneously, we prepare action plans for each competing option before deciding between and executing one of those plans. However, in natural, everyday environments, our available action options frequently change from one moment to the next, and there is often uncertainty as to whether additional options will become available before having to select a particular course of action. Here, with the use of a target-directed reaching task, we show that in this situation, the brain specifies a competing action for each new, sequentially presented potential target and that recently formed action plans can be revisited and updated so as to conform with separate, more newly developed, plans. These findings indicate that the brain forms labile motor plans for sequentially arising target options that can be flexibly restructured to accommodate new motor plans. PMID:27030738

  4. Involvement of Ethylene in the Action of the Cotton Defoliant Thidiazuron 1

    PubMed Central

    Suttle, Jeffrey C.

    1985-01-01

    The effect of the defoliant thidiazuron (N-phenyl-N′-1,2,3-thiadiazol-5-ylurea) on endogenous ethylene evolution and the role of endogenous ethylene in thidiazuron-mediated leaf abscission were examined in cotton (Gossypium hirsutum L. cv Stoneville 519) seedlings. Treatment of 20- to 30-day-old seedlings with thidiazuron at concentrations equal to or greater than 10 micromolar resulted in leaf abscission. At a treatment concentration of 100 micromolar, nearly total abscission of the youngest leaves was observed. Following treatment, abscission of the younger leaves commenced within 48 hours and was complete by 120 hours. A large increase in ethylene evolution from leaf blades and abscission zone explants was readily detectable within 24 hours of treatment and persisted until leaf fall. Ethylene evolution from treated leaf blades was greatest 1 day posttreatment and reached levels in excess of 600 nanoliters per gram fresh weight per hour (26.7 nanomoles per gram fresh weight per hour). The increase in ethylene evolution occurred in the absence of increased ethane evolution, altered leaf water potential, or decreased chlorophyll levels. Treatment of seedlings with inhibitors of ethylene action (silver thiosulfate, hypobaric pressure) or ethylene synthesis (aminoethoxyvinylglycine) resulted in an inhibition of thidiazuron-induced defoliation. Application of exogenous ethylene or 1-aminocyclopropane-1-carboxylic acid largely restored the thidiazuron response. The results indicate that thidiazuron-induced leaf abscission is mediated, at least in part, by an increase in endogenous ethylene evolution. However, alterations of other phytohormone systems thought to be involved in regulating leaf abscission are not excluded by these studies. PMID:16664229

  20. Extradyadic involvement and relationship dissolution in heterosexual women university students.

    PubMed

    Negash, Sesen; Cui, Ming; Fincham, Frank D; Pasley, Kay

    2014-04-01

    This study examined the role of extradyadic involvement (EDI) in heterosexual dating relationships among young adult females (N = 539). A considerable percentage of participants (36 %) reported that they had engaged in an extradyadic emotional or sexual relationship within the last 2 months. Results from logistic regression analyses supported the general hypothesis that emotional and sexual EDI were both significantly associated with relationship dissolution. These associations remained strong even after controlling for participants' age, relationship duration, and relationship quality. The findings also showed that the strength of the association between acts of emotional or sexual extradyadic behaviors and relationship dissolution was linked to relationship quality, gender of the actor, and type of EDI (emotional vs. sexual). Specifically, compared to participants who reported poor relationship quality, those who reported high relationship quality were more likely to end the partnership if they reported emotional or sexual EDI. Findings suggest that individuals in higher quality relationships appear to have considerably more to lose in their relationship when emotional or sexual EDI occurs. This, in part, may be because the more satisfactory the relationship the more disillusionment one may feel when betrayed by their romantic partner. Overall, the present findings underscore the multifaceted nature of the relationships between EDI and relationship dissolution. We call for more research that rigorously examines what contextual factors influence young adults in dating relationships to dissolve relationships following EDI. PMID:24346867

  3. Calculus limits involving infinity: the role of students' informal dynamic reasoning

    NASA Astrophysics Data System (ADS)

    Jones, Steven R.

    2015-01-01

    Few studies on calculus limits have centred their focus on student understanding of limits at infinity or infinite limits that involve continuous functions (as opposed to discrete sequences). This study examines student understanding of these types of limits using both pure mathematics and applied-science functions and formulas. Seven calculus students' approaches to understanding, calculating, and interpreting answers to these types of limits are examined. The dynamic reasoning used by these students led to good justifications and meaningful interpretations of their answers. On the other hand, when students engaged less with dynamic reasoning, they struggled more and made less reasonable interpretations of their answers. Furthermore, dynamic reasoning helped the students in this study overcome previously documented pitfalls and encouraged covariational reasoning. The applied-science contexts at times helped the students engage in dynamic reasoning.

    Fermin, Alan S R; Yoshida, Takehiko; Yoshimoto, Junichiro; Ito, Makoto; Tanaka, Saori C; Doya, Kenji

    2016-01-01

    Humans can select actions by learning, planning, or retrieving motor memories. Reinforcement Learning (RL) associates these processes with three major classes of strategies for action selection: exploratory RL learns state-action values by exploration, model-based RL uses internal models to simulate future states reached by hypothetical actions, and motor-memory RL selects past successful state-action mapping. In order to investigate the neural substrates that implement these strategies, we conducted a functional magnetic resonance imaging (fMRI) experiment while humans performed a sequential action selection task under conditions that promoted the use of a specific RL strategy. The ventromedial prefrontal cortex and ventral striatum increased activity in the exploratory condition; the dorsolateral prefrontal cortex, dorsomedial striatum, and lateral cerebellum in the model-based condition; and the supplementary motor area, putamen, and anterior cerebellum in the motor-memory condition. These findings suggest that a distinct prefrontal-basal ganglia and cerebellar network implements the model-based RL action selection strategy. PMID:27539554

    2006-01-01

    We report an extensive study of variability in genes encoding proteins that are believed to be involved in the action and biotransformation of warfarin. Warfarin is a commonly prescribed anticoagulant that is difficult to use because of the wide interindividual variation in dose requirements, the narrow therapeutic range and the risk of serious bleeding. We genotyped 201 patients for polymorphisms in 29 genes in the warfarin interactive pathways and tested them for association with dose requirement. In our study, polymorphisms in or flanking the genes VKORC1, CYP2C9, CYP2C18, CYP2C19, PROC, APOE, EPHX1, CALU, GGCX and ORM1-ORM2 and haplotypes of VKORC1, CYP2C9, CYP2C8, CYP2C19, PROC, F7, GGCX, PROZ, F9, NR1I2 and ORM1-ORM2 were associated with dose (P < 0.05). VKORC1, CYP2C9, CYP2C18 and CYP2C19 were significant after experiment-wise correction for multiple testing (P < 0.000175), however, the association of CYP2C18 and CYP2C19 was fully explained by linkage disequilibrium with CYP2C9*2 and/or *3. PROC and APOE were both significantly associated with dose after correction within each gene. A multiple regression model with VKORC1, CYP2C9, PROC and the non-genetic predictors age, bodyweight, drug interactions and indication for treatment jointly accounted for 62% of variance in warfarin dose. Weaker associations observed for other genes could explain up to ∼10% additional dose variance, but require testing and validation in an independent and larger data set. Translation of this knowledge into clinical guidelines for warfarin prescription will be likely to have a major impact on the safety and efficacy of warfarin.

    2016-01-01

    ABSTRACT Numerous studies have shown the ability of humic substances to improve plant development. This action is normally reflected in an enhancement of crop yields and quality. However, the mechanisms responsible for this action of humic substances remain rather unknown. Our studies have shown that the shoot promoting action of sedimentary humic acids is dependent of its ability to increase root hydraulic conductivity through signaling pathways related to ABA, which in turn is affected in roots by humic acids in an IAA-NO dependent way. Furthermore, these studies also indicate that the primary action of humic acids in roots might also be physical, resulting from a transient mild stress caused by humic acids associated with a fouling-cleaning cycle of wall cell pores. Finally the role of alternative signal molecules, such as ROS, and corresponding signaling pathways are also discussed and modeled in the context of the above-mentioned framework. PMID:26966789

    2014-01-01

    The purpose of this exploratory study was to examine the direct and indirect effects of early parenting on later parental school involvement and student achievement. The sample, pulled from the first and second waves of the Panel Study of Income Dynamics – Child Development Supplement data set, consisted of 390 children ages 2–5 at time 1 and their families. Fathers’ and mothers’ participation in five dimensions of early parenting behaviors were assessed at time 1, while later parental school involvement and student achievement were assessed at time 2. Although early paternal and maternal parenting behaviors were not directly related to later student achievement, differences were revealed in the pattern of relationships between early parenting and later parental school involvement for fathers and mothers. In addition, fathers’ later school involvement was found to be negatively related to student achievement while maternal school involvement was found to be positively related to student achievement. These findings provide partial support for the hypothesized differential relationship between fathers’ and mothers’ early parenting and later student achievement. PMID:25414521

    Metformin, one of the most commonly used drugs for patients with type 2 diabetes, recently has received much attention regarding its anti-cancer action. It is thought that the suppression of mTOR signaling is involved in metformin's anti-cancer action. Although liver cancer is one of the most responsive types of cancer for reduction of incidence by metformin, the molecular mechanism of the suppression of mTOR in liver remains unknown. In this study, we investigated the mechanism of the suppressing effect of metformin on mTOR signaling and cell proliferation using human liver cancer cells. Metformin suppressed phosphorylation of p70-S6 kinase, and ribosome protein S6, downstream targets of mTOR, and suppressed cell proliferation. We found that DEPTOR, an endogenous substrate of mTOR suppression, is involved in the suppressing effect of metformin on mTOR signaling and cell proliferation in human liver cancer cells. Metformin increases the protein levels of DEPTOR, intensifies binding to mTOR, and exerts a suppressing effect on mTOR signaling. This increasing effect of DEPTOR by metformin is regulated by the proteasome degradation system; the suppressing effect of metformin on mTOR signaling and cell proliferation is in a DEPTOR-dependent manner. Furthermore, metformin exerts a suppressing effect on proteasome activity, DEPTOR-related mTOR signaling, and cell proliferation in an AMPK-dependent manner. We conclude that DEPTOR-related mTOR suppression is involved in metformin's anti-cancer action in liver, and could be a novel target for anti-cancer therapy. - Highlights: • We elucidated a novel pathway of metformin's anti-cancer action in HCC cells. • DEPTOR is involved in the suppressing effect of metformin on mTOR signaling. • Metformin increases DEPTOR protein levels via suppression of proteasome activity. • DEPTOR-related mTOR suppression is involved in metformin's anti-cancer action.

    Research has consistently found that school students who do not identify as self-declared completely heterosexual are at increased risk of victimization by bullying from peers. This study examined heterosexual and nonheterosexual university students' involvement in both traditional and cyber forms of bullying, as either bullies or victims. Five hundred twenty-eight first-year university students (M=19.52 years old) were surveyed about their sexual orientation and their bullying experiences over the previous 12 months. The results showed that nonheterosexual young people reported higher levels of involvement in traditional bullying, both as victims and perpetrators, in comparison to heterosexual students. In contrast, cyberbullying trends were generally found to be similar for heterosexual and nonheterosexual young people. Gender differences were also found. The implications of these results are discussed in terms of intervention and prevention of the victimization of nonheterosexual university students. PMID:23078337

  17. Remediation of at-risk medical students: theory in action

    PubMed Central

    2013-01-01

    Background Previous work has shown that a programme that draws on a blend of theories makes a positive difference to outcomes for students who fail and repeat their first semester at medical school. Exploration of student and teacher perspectives revealed that remediation of struggling medical students can be achieved through a cognitive apprenticeship within a small community of inquiry. This community needs expert teachers capable of performing a unique combination of roles (facilitator, nurturing mentor, disciplinarian, diagnostician and role model), with high levels of teaching presence and practical wisdom. Yet, despite participants’ convergent opinions on the elements of effective remediation, significant differences were found between outcomes of students working with experienced and inexperienced teachers. The current study explores the actual practice of teachers on this remediation course, aiming to exemplify elements of our theory of remediation and explore differences between teachers. Methods Since it is in the classroom context that the interactions that constitute the complex process of remediation emerge, this practice-based research has focused on direct observation of classroom teaching. Nineteen hours of small group sessions were recorded and transcribed. Drawing on ethnography and sociocultural discourse analysis, selected samples of talk-in-context demonstrate how the various elements of remediation play out in practice, highlighting aspects that are most effective, and identifying differences between experienced and novice teachers. Results Long-term student outcomes are strongly correlated to teacher experience (r, 0.81). Compared to inexperienced teachers, experienced teachers provide more challenging, disruptive facilitation, and take a dialogic stance that encourages more collaborative group dynamics. They are more expert at diagnosing cognitive errors, provide frequent metacognitive time-outs and make explicit links across the

    Parental involvement in education remains important for facilitating positive youth development. This study conceptualized parental involvement as a multidimensional construct-including school-based involvement, home-based involvement, and academic socialization-and examined the effects of different types of parental involvement in 10th grade on student achievement and depression in 11th grade (approximately ages 15-17 years). In addition, this study tested whether parental involvement influenced adolescent outcomes by increasing their academic engagement in school. A total of 1,056 adolescents participated in the study (51% males; 53% European American, 40% African American, and 7% other). Parental involvement was found to improve academic and emotional functioning among adolescents. In addition, parental involvement predicted adolescent academic success and mental health both directly and indirectly through behavioral and emotional engagement. PMID:24033259

    Background: Lecture is a common traditional method for teaching, but it may not stimulate higher order thinking and students may also be hesitant to express and interact. The postgraduate (PG) students are less involved with undergraduate (UG) teaching. Team based small group active learning method can contribute to better learning experience. Aim: To-promote active learning skills among the UG students using small group teaching methods involving PG students as facilitators to impart hands-on supervised training in teaching and managerial skills. Methodology: After Institutional approval under faculty supervision 92 UGs and 8 PGs participated in 6 small group sessions utilizing the jigsaw technique. Feedback was collected from both. Observations: Undergraduate Feedback (Percentage of Students Agreed): Learning in small groups was a good experience as it helped in better understanding of the subject (72%), students explored multiple reading resources (79%), they were actively involved in self-learning (88%), students reported initial apprehension of performance (71%), identified their learning gaps (86%), team enhanced their learning process (71%), informal learning in place of lecture was a welcome change (86%), it improved their communication skills (82%), small group learning can be useful for future self-learning (75%). Postgraduate Feedback: Majority performed facilitation for first time, perceived their performance as good (75%), it was helpful in self-learning (100%), felt confident of managing students in small groups (100%), as facilitator they improved their teaching skills, found it more useful and better identified own learning gaps (87.5%). Conclusions: Learning in small groups adopting team based approach involving both UGs and PGs promoted active learning in both and enhanced the teaching skills of the PGs. PMID:26380201

    Chagas’ disease, a vector-transmitted infectious disease, is caused by the protozoa parasite Trypanosoma cruzi. Drugs that are currently available for the treatment of this disease are unsatisfactory, making the search for new chemotherapeutic agents a priority. We recently described the trypanocidal action of (−)-elatol, extracted from the macroalga Laurencia dendroidea. However, nothing has been described about the mechanism of action of this compound on amastigotes that are involved in the chronic phase of Chagas’ disease. The goal of the present study was to evaluate the effect of (−)-elatol on the formation of superoxide anions (O2•−), DNA fragmentation, and autophagy in amastigotes of T. cruzi to elucidate the possible mechanism of the trypanocidal action of (−)-elatol. Treatment of the amastigotes with (−)-elatol increased the formation of O2•− at all concentrations of (−)-elatol assayed compared with untreated parasites. Increased fluorescence was observed in parasites treated with (−)-elatol, indicating DNA fragmentation and the formation of autophagic compartments. The results suggest that the trypanocidal action of (−)-elatol might involve the induction of the autophagic and apoptotic death pathways triggered by an imbalance of the parasite’s redox metabolism.

  5. Baking together-the coordination of actions in activities involving people with dementia.

    PubMed

    Majlesi, Ali Reza; Ekström, Anna

    2016-08-01

    This study explores interaction and collaboration between people with dementia and their spouses in relation to the performance of household chores with the focus on instruction as an interactional context to engage the person with dementia in collaboration to accomplish joint activities. Dementia is generally associated with pathological changes in people's cognitive functions such as diminishing memory functions, communicative abilities and also diminishing abilities to take initiative as well as to plan and execute tasks. Using video recordings of everyday naturally occurring activities, we analyze the sequential organization of actions (see Schegloff, 2007) oriented toward the accomplishment of a joint multi-task activity of baking. The analysis shows the specific ways of collaboration through instructional activities in which the person with dementia exhibits his competence and skills in accomplishing the given tasks through negotiating the instructions with his partner and carrying out instructed actions. Although the driving force of the collaboration seems to be a series of directive sequences only initiated by the partner throughout the baking activity, our analyses highlight how the person with dementia can actively use the material environment-including collaborating partners-to compensate for challenges and difficulties encountered in achieving everyday tasks. The sequential organization of instructions and instructed actions are in this sense argued to provide an interactional environment wherein the person with dementia can make contributions to the joint activity in an efficient way. While a collaborator has been described as necessary for a person with dementia to be able to partake in activities, this study shows that people with dementia are not only guided by their collaborators in joint activities but they can also actively use their collaborators in intricate compensatory ways.

    NASA Astrophysics Data System (ADS)

    Rosen, Rachel; Heatherly, S.; McLauglin, M.; Lorimer, D.

    2010-01-01

    The National Science Foundation funded "Pulsar Search Collaboratory” project is a collaboration between the National Radio Astronomy Observatory (NRAO) in Green Bank, WV and West Virginia University aimed at provoking interest in Science-Technology-Engineering-Math (STEM) careers and increasing scientific and information technology literacy among high-school students within the state and region. Over the initial three-year phase of this program, 60 high-school teachers at schools throughout region and over 300 students will be involved in the search for new pulsars and transient objects by analyzing over 30 TB of data collected by the Green Bank Telescope in 2007. Although training is provided to teachers and student leaders via a summer workshop, additional students may join the program, learning from their peers how to conduct the data analysis. We are now in the second year of the PSC and we present a progress report from the first year of the PSC. We will summarize our approaches to implementing this challenging project, including the use of online tools to communicate with and sustain interest among the student teams, and the development of a unique graphical database through which students access and analyze pulsar plots. We will present the student results including one astronomical discovery as well as statistics on the plots that students have analyzed, including distribution among schools, number of known pulsars found, and RFI detection. Finally we will present evaluation results and lessons learned from the first year of the PSC. These include results from pre/post testing of teachers and students that show changes in student interest in STEM careers resulting from the PSC, and statistics on student participation.

  11. Students' Involvement in Authentic Modelling Practices as Contexts in Chemistry Education

    NASA Astrophysics Data System (ADS)

    Prins, Gjalt T.; Bulte, Astrid M. W.; van Driel, Jan H.; Pilot, Albert

    2009-11-01

    In science education students should come to understand the nature and significance of models. A promising strategy to achieve this goal is using authentic modelling practices as contexts for meaningful learning of models and modelling. An authentic practice is defined as professionals working with common motives and purposes, pertaining to a similar type of procedure and applying relevant knowledge on the modelling issue they work on. In this study we evaluate whether the use of authentic practices initiates adequate students’ involvement. This was done by investigating students’ interests, ownership, familiarity and complexity. In addition, we evaluated students’ expressed modelling procedures in response to the modelling issues. We designed learning tasks which were enacted by a focus group of students. Three primary data sources were used to collect data. Firstly, a group discussion was organised in which students’ reflected on both authentic practices. Secondly, students filled in written questionnaires containing items on affective and cognitive aspects. Thirdly, the realised modelling procedures by students were analysed. The results show that students’ involvement was successfully initiated, evidenced by motivated students, willingness to continue and the completeness and quality of the realised modelling procedures. The design of the learning tasks proved to be successful in realising this involvement. The results obtained in this study support the strategy of using authentic modelling practices as contexts for meaningful learning of models and modelling.

  12. Involvement of PPARγ in the antitumoral action of cannabinoids on hepatocellular carcinoma.

    PubMed

    Vara, D; Morell, C; Rodríguez-Henche, N; Diaz-Laviada, I

    2013-01-01

    Cannabinoids exert antiproliferative effects in a wide range of tumoral cells, including hepatocellular carcinoma (HCC) cells. In this study, we examined whether the PPARγ-activated pathway contributed to the antitumor effect of two cannabinoids, Δ9-tetrahydrocannabinol (THC) and JWH-015, against HepG2 and HUH-7 HCC cells. Both cannabinoids increased the activity and intracellular level of PPARγ mRNA and protein, which was abolished by the PPARγ inhibitor GW9662. Moreover, genetic ablation with small interfering RNA (siRNA), as well as pharmacological inhibition of PPARγ decreased the cannabinoid-induced cell death and apoptosis. Likewise, GW9662 totally blocked the antitumoral action of cannabinoids in xenograft-induced HCC tumors in mice. In addition, PPARγ knockdown with siRNA caused accumulation of the autophagy markers LC3-II and p62, suggesting that PPARγ is necessary for the autophagy flux promoted by cannabinoids. Interestingly, downregulation of the endoplasmic reticulum stress-related protein tribbles homolog 3 (TRIB3) markedly reduced PPARγ expression and induced p62 accumulation, which was counteracted by overexpression of PPARγ in TRIB3-knocked down cells. Taken together, we demonstrate for the first time that the antiproliferative action of the cannabinoids THC and JWH-015 on HCC, in vitro and in vivo, are modulated by upregulation of PPARγ-dependent pathways.

    An analysis of reported state and federal adjudication from 1950 through 1989 was undertaken to identify trends in litigation involving medical students and undergraduate medical education. Of the 110 cited judicial decisions during that time, 59 (54%) involved disputes over financing medical education; 43 (73%) were litigated since 1985. This dramatic increase arises primarily from challenges to National Health Service Corps obligations and from attempts to discharge or reorganize debt under the Bankruptcy Code. Medical school graduates enjoyed very little success in these cases. Analysis of court decisions points to a need for informed counseling for medical students, particularly as to the consequences of timing in default on service obligations and of incurring loans under the Health Education Assistance Loan (HEAL) program as opposed to other loan sources. The growing educational debt of today's medical students foreshadows continued litigation in this area. PMID:1993104

    During the 1980-81 academic year, NASA established the Shuttle Student Involvement Project for Secondary Schools (SSIP), an annual competition which invites students to propose experiments suitable for flight aboard the Space Shuttle. The purpose of the project is to stimulate the teaching and study of science and engineering among students in grades 9 through 12. Results of the first year of the project have been reported. The second competition was announced in September 1981. With a February 1, 1982 deadline, 2,800 proposals were submitted. Twenty national winners were announced in May 1982. NASA is now pairing the 20 winners with a corporate sponsor and with a NASA scientist or engineer to work with the student. Most SSIP experiments are performed in the Orbiter's mid-deck, and receive up to one hour of crew time. Attention is given to the desired outcomes of SSIP, and the SSIP experiments.

    This article is part of a Special Issue ("Estradiol and cognition"). Estrogens have repeatedly been shown to influence a wide array of social behaviors, which in rodents are predominantly olfactory-mediated. Estrogens are involved in social behavior at multiple levels of processing, from the detection and integration of socially relevant olfactory information to more complex social behaviors, including social preferences, aggression and dominance, and learning and memory for social stimuli (e.g. social recognition and social learning). Three estrogen receptors (ERs), ERα, ERβ, and the G protein-coupled ER 1 (GPER1), differently affect these behaviors. Social recognition, territorial aggression, and sexual preferences and mate choice, all requiring the integration of socially related olfactory information, seem to primarily involve ERα, with ERβ playing a lesser, modulatory role. In contrast, social learning consistently responds differently to estrogen manipulations than other social behaviors. This suggests differential ER involvement in brain regions important for specific social behaviors, such as the ventromedial and medial preoptic nuclei of the hypothalamus in social preferences and aggression, the medial amygdala and hippocampus in social recognition, and the prefrontal cortex and hippocampus in social learning. While the long-term effects of ERα and ERβ on social behavior have been extensively investigated, our knowledge of the rapid, non-genomic, effects of estrogens is more limited and suggests that they may mediate some social behaviors (e.g. social learning) differently from long-term effects. Further research is required to compare ER involvement in regulating social behavior in male and female animals, and to further elucidate the roles of the more recently described G protein-coupled ERs, both the GPER1 and the Gq-mER.

    Bullying, especially in developing countries, has not been much examined, especially the influence of parents on the risk of being bullied. The aim of this study was to determine whether active parenting is associated with reduced peer victimization among middle-school students in North Africa. A secondary analysis of data from more than 13,000 middle-school students who participated in the Global School-based Student Health Survey (GSHS) in Egypt, Libya, Morocco and Tunisia between 2006 and 2008, was conducted using multiple logistic regression models. About 60% of students in Egypt and one-third of students in Libya, Morocco and Tunisia reported having been bullied in the past month. In all 4 countries, boys reported more peer victimization than girls. In Egypt, Morocco and Tunisia, students who reported that their parents checked their homework, were understanding, and knew how the student spent free time had a reduced likelihood of peer victimization but this association was not significant in Libya. Interventions for reducing bullying should consider the positive impact of involved parents. PMID:23879073

    Assessment has long been recognised as the single most influential factor in shaping what and how students in higher education choose to learn and the quality of learning outcomes depends on the quality of assessment. Within intellectual disability nursing the student are prepared within a biopsychosocial educational model and curriculum address these challenges. Structured student debates have great potential for promoting competence and in-depth knowledge of substantive topics relevant to practice. Like other interactive assignments designed to more closely resemble real-world activities, issue-oriented debates actively engage students in course content. Allowing students to develop and exercise skills that translate to practice activities. Most importantly debates help to stimulate critical thinking by shaking students free from established opinions and helping them to appreciate the complexities involved in practice. This article identifies the use of a debate as an assessment method within an intellectual disability nursing programme and a student's reflective comment on the process, and their experience of a debate as their assessment method.

    Isolated microspores are reprogrammed in vitro by stress, becoming totipotent cells and producing embryos and plants via a process known as microspore embryogenesis. Despite the abundance of data on auxin involvement in plant development and embryogenesis, no data are available regarding the dynamics of auxin concentration, cellular localization and the expression of biosynthesis genes during microspore embryogenesis. This work involved the analysis of auxin concentration and cellular accumulation; expression of TAA1 and NIT2 encoding enzymes of two auxin biosynthetic pathways; expression of the PIN1-like efflux carrier; and the effects of inhibition of auxin transport and action by N-1-naphthylphthalamic acid (NPA) and α-(p-chlorophenoxy) isobutyric acid (PCIB) during Brassica napus microspore embryogenesis. The results indicated de novo auxin synthesis after stress-induced microspore reprogramming and embryogenesis initiation, accompanying the first cell divisions. The progressive increase of auxin concentration during progression of embryogenesis correlated with the expression patterns of TAA1 and NIT2 genes of auxin biosynthetic pathways. Auxin was evenly distributed in early embryos, whereas in heart/torpedo embryos auxin was accumulated in apical and basal embryo regions. Auxin efflux carrier PIN1-like gene expression was induced in early multicellular embryos and increased at the globular/torpedo embryo stages. Inhibition of polar auxin transport (PAT) and action, by NPA and PCIB, impaired embryo development, indicating that PAT and auxin action are required for microspore embryo progression. NPA also modified auxin embryo accumulation patterns. These findings indicate that endogenous auxin biosynthesis, action and polar transport are required in stress-induced microspore reprogramming, embryogenesis initiation and progression.

    Photosynthesis is not required for the toxicity of diphenyl ether herbicides, nor are chloroplast thylakoids the primary site of diphenyl ether herbicide activity. Isolated spinach (Spinacia oleracea L.) chloroplast fragments produced malonyl dialdehyde, indicating lipid peroxidation, when paraquat (1,1'-dimethyl-4,4'-bipyridinium ion) or diuron [3-(3,4-dichlorophenyl)-1,1-dimethylurea] were added to the medium, but no malonyl dialdehyde was produced when chloroplast fragments were treated with the methyl ester of acifluorfen (methyl 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid), oxyfluorfen [2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluoromethyl)benzene], or MC15608 (methyl 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-chlorobenzoate). In most cases the toxicity of acifluorfen-methyl, oxyfluorfen, or MC15608 to the unicellular green alga Chlamydomonas eugametos (Moewus) did not decrease after simultaneous treatment with diuron. However, diuron significantly reduced cell death after paraquat treatment at all but the highest paraquat concentration tested (0.1 millimolar). These data indicate electron transport of photosynthesis is not serving the same function for diphenyl ether herbicides as for paraquat. Additional evidence for differential action of paraquat was obtained from the superoxide scavenger copper penicillamine (copper complex of 2-amino-3-mercapto-3-methylbutanoic acid). Copper penicillamine eliminated paraquat toxicity in cucumber (Cucumis sativus L.) cotyledons but did not reduce diphenyl ether herbicide toxicity. PMID:16664206

  2. The use of parent involved take-home science activities during student teaching: Understanding the challenges of implementation

    The purpose of this study was to identify student teachers use and implementation of Science in a Bag when it was no longer a required course-based assessment. This take-home science activity acted as the elaboration component of the 5Es lesson teacher candidates designed and taught in the classroom, utilized household items, and directly involved parents in their child's education. The purposeful sample was comprised of six teacher candidates during their student teaching practicum, the last semester of the childhood education teacher certification program. This collective case study centered on student teachers' use of the focused activity, Science in a Bag, in order to gain knowledge of challenges faced in applying take-home science kits and working with parents. Data collection was comprised of student teacher and parent interviews, candidate reflections, as well as in-class observations and discussions carried out during weekly seminars. Data collection occurred throughout the seven-week student teaching practicum. The four research questions were: 1) What factors do teacher candidates identify as interfering with their ability to implement Science in a Bag during student teaching placements? 2) What factors do teacher candidates identify as enhancing their ability to carry out Science in a Bag? 3) What forms of support do teacher candidates believe are important to their success in implementing Science in a Bag during student teaching? 4) How do teacher candidates deal with obstacles when implementing Science in a Bag? Despite the fact that no student teacher was prohibited from implementing Science in a Bag, the level to which candidates valued and utilized this instructional strategy varied compared to how they were taught and practiced it during the science methods course. Some student teachers attempted to hide their feelings toward Science in a Bag, however their actions revealed that they were simply carrying out the instructional strategy because they

  3. Transfer students in STEM majors at a Midwestern University: Academic and social involvement factors that influence student success

    There is soon-to-be a shortage of qualified U.S. workers in science, technology, engineering, and mathematics (STEM). As a result, many science-related jobs are being filled by technically-skilled foreign workers. If the U.S wants to maintain its global economic leadership, then it must ensure a continuous growth of highly-trained individuals in STEM disciplines. Therefore, American institutions of higher education, including community colleges, must identify potential factors that contribute to the lack of interest in STEM majors, as well as the low rate of success of students who enter STEM majors but struggle to finish their degrees. The purpose of this study was to ascertain the perceptions of community college transfer students who are pursuing bachelor degrees in STEM majors at Iowa State University (ISU). What were their transfer experiences and what influenced their academic success in STEM. Participants were encouraged to share their transfer experiences while at the community college as well as their experiences on the ISU campus. They were also asked about their level of academic involvement, their relationships with faculty, and their participation in peer group activities prior to and after transferring. The research design included both quantitative and qualitative components, which provided an in-depth look at the experiences of STEM non-engineering and engineering students. Quantitative data include students' background characteristics, demographic information, and college activities at the community college and ISU. Qualitative data were used to illuminate students' overall transfer experience and their successful journey in STEM fields. The combination of quantitative and qualitative methods allowed a better understanding of the strategies students put into practice once they transfer from a community college to a four-year institution in pursuit of a STEM bachelor's degree. The results of this study suggest that there is an association among the

    The present study aimed to determine estrogen feedback action sites to mediate prepubertal restraint of gonadotropin-releasing hormone (GnRH)/luteinizing hormone (LH) release in female rats. Wistar-Imamichi strain rats were ovariectomized (OVX) and received a local estradiol-17β (estradiol) or cholesterol microimplant in several brain areas, such as the medial preoptic area (mPOA), paraventricular nucleus, ventromedial nucleus and arcuate nucleus (ARC), at 20 or 35 days of age. Six days after receiving the estradiol microimplant, animals were bled to detect LH pulses at 26 or 41 days of age, representing the pre- or postpubertal period, respectively. Estradiol microimplants in the mPOA or ARC, but not in other brain regions, suppressed LH pulses in prepubertal OVX rats. Apparent LH pulses were found in the postpubertal period in all animals bearing estradiol or cholesterol implants. It is unlikely that pubertal changes in responsiveness to estrogen are due to a change in estrogen receptor (ER) expression, because the number of ERα-immunoreactive cells and mRNA levels of Esr1, Esr2 and Gpr30 in the mPOA and ARC were comparable between the pre- and postpubertal periods. In addition, kisspeptin or GnRH injection overrode estradiol-dependent prepubertal LH suppression, suggesting that estrogen inhibits the kisspeptin-GnRH cascade during the prepubertal period. Thus, estrogen-responsive neurons located in the mPOA and ARC may play key roles in estrogen-dependent prepubertal restraint of GnRH/LH secretion in female rats. PMID:26004302

    The association between the percent change in first-year and total underrepresented minority student enrollment and the presence of preadmission programs at Liaison Committee on Medical Education (LCME) accredited medical schools was assessed before and during successful legal and legislative challenges to affirmative action. The percent change in under-represented minority student enrollment was determined by comparing enrollment data for the academic years 1993-94 and 1996-97. Schools were categorized as having either a negative or positive percent change in their enrollment of underrepresented minority students. Logistic regression was used to determine the association of the percent change in under-represented minority student enrollment and the presence of a preadmission program while controlling for schools' financial support and the presence of postbaccalaureate programs. Fifty-six percent of the included medical schools had preadmission programs. Schools with a positive percent change were significantly more likely to have preadmission programs compared with schools with a negative percent change. There was no association between the presence of preadmission programs and the percent change in total enrollment. These results indicate that the presence of preadmission programs is positively associated with increases in first-year underrepresented minority student enrollment during the successful challenges to affirmative actions.

    Undergraduate students associated with The George Washington University and UMass Dartmouth have had the opportunity to participate in nuclear physics research as a part of the PIONS@MAXLAB Collaboration performing experiments at MAX-lab at Lund University in Sweden. This project has supported thirteen undergraduate students during 2009 - 2011. The student researchers are involved with all aspects of the experiments performed at the laboratory, from set-up to analysis and presentation at national conferences. These experiments investigate the dynamics responsible for the internal structure of the nucleon through the study of pion photoproduction off the nucleon and high-energy Compton scattering. Along with the US and Swedish project leaders, members of the collaboration (from four different countries) have contributed to the training and mentoring of these students. This program provides students with international research experiences that prepare them to operate successfully in a global environment and encourages them to stay in areas of science, technology, engineering and math (STEM) that are crucial for our modern, technology-dependent society. We will present the history, goals and outcomes in both physics results and student success that have come from this program. This work supported by NSF OISE/IRES award 0553467.

    1988-03-01

    The toxicity of the intercalating compounds 9-aminoellipticine (9AE) and isopropyl-oxazolopyridocarbazole (Ipr-OPC) were studied. The inhibitory effect of non-toxic doses of 9AE, which incises DNA at apurinic (AP) sites, or Ipr-OPC, which does not cleave DNA at AP sites, with non-toxic doses of the alkylating agent dimethylsulphate (DMS) on the growth of Escherichia coli strain AB1157, is additive. The same result has been observed with an exonuclease III mutant which has only 10% of the AP endonuclease activity. However, 9AE or Ipr-OPC display a synergistic toxic effect with a DMS concentration which allows 20% of E. coli AB1157 survival. This synergy is increased for 9AE in the AP endonuclease mutant when compared to the wild-type strain. Under identical conditions 9AE and Ipr-OPC have no synergistic effect on a mutant deficient in the enzymes which generate AP sites. Therefore AP sites are involved in the synergistic toxicity of DMS and the studied intercalating agents. However, the precise role of the interaction of intercalating agents with AP sites, either without cleavage (type 1 compounds) or with cleavage (type 2 compounds), in the observed effect remains an open question.

    This study employs latent class analysis to construct bullying involvement typologies among 3114 students (48% male, 58% White) in 40 middle schools across the U.S. Four classes were constructed: victims (15%); bullies (13%); bully-victims (13%); and noninvolved (59%). Respondents who were male and participated in fewer conventional activities were more likely to be members of the victims class. Students who were African-American and reported being less successful at school had a higher likelihood of membership in the bullies class. Bully-victims shared characteristics with bullies and victims: Students with more feelings of anger toward others and a higher tendency toward sensation-seeking had a higher likelihood of membership in the bullies and bully-victims classes, whereas lower levels of social inclusion was associated with membership in the victims and bully-victims classes.

    Aminobisphosphonates (aminoBPs) are potent inhibitors of bone resorption. However, they cause undesirable inflammatory reactions, including fever, in humans. Intraperitoneal injection of aminoBPs into mice also induces inflammatory reactions, including a prolonged elevation of the activity of the histamine-forming enzyme, histidine decarboxylase (HDC). Because interleukin-1 (IL-1) is a typical pyrogen and a strong inducer of HDC, we examined whether aminoBPs induce inflammatory reactions in mice deficient in genes for both IL-1α and IL-1β (IL-1-KO mice). In control mice, aminoBPs induced an elevation of HDC activity and other inflammatory reactions (enlargement of the spleen, atrophy of the thymus, exudate in the thorax and increase in granulocytic cells in the peritoneal cavity). These responses were all weak or undetectable in IL-1-KO mice. We have previously shown that lipopolysaccharides (LPSs) from Escherichia coli and Prevotella intermedia (a prevalent gram-negative bacterium both in periodontitis and endodontal infections) are capable of inducing HDC activity in various tissues in mice. In control mice treated with an aminoBP, the LPS-induced elevations of serum IL-1 (α and β) and tissue HDC activity were both markedly augmented. However, such an augmentation of HDC activity was small or undetectable in IL-1-KO mice. These results, taken together with our previous findings (i) suggest that IL-1 is involved in the aminoBP-induced inflammatory reactions and (ii) lead us to think that under some conditions, inflammatory reactions induced by gram-negative bacteria might be augmented in patients treated with an aminoBP. In this study, we also obtained a result suggesting that IL-1-deficiency might be compensated by a second, unidentified, mechanism serving to induce HDC in response to LPS when IL-1 is lacking.

    The striatum is the most prominent nucleus in the basal ganglia and plays an important role in motor movement regulation. The cholinergic interneurons (ChIs) in striatum are involved in the motion regulation by releasing acetylcholine (ACh) and modulating the output of striatal projection neurons. Here, we report that muscarinic ACh receptor (M receptor) agonists, ACh and Oxotremorine (OXO-M), decreased the firing frequency of ChIs by blocking the hyperpolarization-activated cyclic nucleotide-gated (HCN) channels. Scopolamine (SCO), a nonselective antagonist of M receptors, abolished the inhibition. OXO-M exerted its function by activating the Gi/o cAMP signaling cascade. The single-cell reverse transcription polymerase chain reaction (scRT-PCR) revealed that all the five subtypes of M receptors and four subtypes of HCN channels were expressed on ChIs. Among them, M2 receptors and HCN2 channels were the most dominant ones and expressed in every single studied cholinergic interneuron (ChI).Our results suggest that ACh regulates not only the output of striatal projection neurons, but also the firing activity of ChIs themselves by activating presynaptic M receptors in the dorsal striatum. The activation of M2 receptors and blockage of HCN2 channels may play an important role in ACh inhibition on the excitability of ChIs. This finding adds a new G-protein coupled receptor mediated regulation on ChIs and provides a cellular mechanism for control of cholinergic activity and ACh release in the dorsal striatum.

    The c-Myc (Myc) oncoprotein is deregulated in a large proportion of diverse human cancers. Considerable effort has therefore been directed at identifying pharmacologic inhibitors as potential anti-neoplastic agents. Three such groups of small molecule inhibitors have been described. The first is comprised of so-called "direct" inhibitors, which perturb Myc's ability to form productive DNA-binding heterodimers in association with its partner, Max. The second group is comprised of indirect inhibitors, which largely function by targeting the BET-domain protein BRD4 to prevent the proper formation of transcriptional complexes that assemble in response to Myc-Max DNA binding. Thirdly, synthetic lethal inhibitors cause the selective apoptosis of Myc over-expressing either by promoting mitotic catastrophe or altering Myc protein stability. We report here a common mechanism by which all Myc inhibitors, irrespective of class, lead to eventual cellular demise. This involves the depletion of ATP stores due to mitochondrial dysfunction and the eventual down-regulation of Myc protein. The accompanying metabolic de-regulation causes neutral lipid accumulation, cell cycle arrest, and an attempt to rectify the ATP deficit by up-regulating AMP-activated protein kinase (AMPK). These responses are ultimately futile due to the lack of functional Myc to support the requisite anabolic response. Finally, the effects of Myc depletion on ATP levels, cell cycle arrest, differentiation and AMPK activation can be mimicked by pharmacologic inhibition of the mitochondrial electron transport chain without affecting Myc levels. Thus, all Myc inhibitors promote a global energy collapse that appears to underlie many of their phenotypic consequences. PMID:26036281

    The striatum is the most prominent nucleus in the basal ganglia and plays an important role in motor movement regulation. The cholinergic interneurons (ChIs) in striatum are involved in the motion regulation by releasing acetylcholine (ACh) and modulating the output of striatal projection neurons. Here, we report that muscarinic ACh receptor (M receptor) agonists, ACh and Oxotremorine (OXO-M), decreased the firing frequency of ChIs by blocking the hyperpolarization-activated cyclic nucleotide-gated (HCN) channels. Scopolamine (SCO), a nonselective antagonist of M receptors, abolished the inhibition. OXO-M exerted its function by activating the Gi/o cAMP signaling cascade. The single-cell reverse transcription polymerase chain reaction (scRT-PCR) revealed that all the five subtypes of M receptors and four subtypes of HCN channels were expressed on ChIs. Among them, M2 receptors and HCN2 channels were the most dominant ones and expressed in every single studied cholinergic interneuron (ChI).Our results suggest that ACh regulates not only the output of striatal projection neurons, but also the firing activity of ChIs themselves by activating presynaptic M receptors in the dorsal striatum.

    This study examined the action tendencies of respect-related emotions in Japanese university students. Participants (n = 405) randomly received a questionnaire about one of six respect-related emotions: (a) keiai (respect mingled with mild love); (b) shinsui (idolatry worship, and adoration); (c) ifu (awe mingled with fear); (d) kanshin (admiration); (e) kyotan (wonder); and (f) sonkei (respect proper) and were asked to recall a situation they felt the emotion. Next, they rated how much they felt like doing the respect-related (intrapersonal or interpersonal) actions in the situation. Statistical analysis revealed several action tendencies of respect-related emotions, however, the degree of each differed between the prototypical episodes of the emotions (a)-(e). The action tendency pattern of sonkei was most similar to that of keiai, therefore keiai could be considered as the prototypical feeling of sonkei in university students. Furthermore, almost all the respect-related emotions tended to strongly motivate willingness for self-correction and improvement. These findings suggest that respect-related emotions play an important role in self-improvement and building good relationships with superiors, at least in late adolescence. PMID:27476262

    Highlights: Black-Right-Pointing-Pointer Glucocorticoid (GC) induced the expression of proton-sensing TDAG8 in macrophages. Black-Right-Pointing-Pointer GC enhanced acidic pH-induced cAMP accumulation and inhibition of TNF-{alpha} production. Black-Right-Pointing-Pointer The enhancement of the GC-induced actions was lost by TDAG8 deficiency. Black-Right-Pointing-Pointer GC-induced anti-inflammatory actions are partly mediated by TDAG8 expression. -- Abstract: Dexamethasone (DEX), a potent glucocorticoid, increased the expression of T-cell death associated gene 8 (TDAG8), a proton-sensing G protein-coupled receptor, which is associated with the enhancement of acidic pH-induced cAMP accumulation, in peritoneal macrophages. We explored the role of increased TDAG8 expression in the anti-inflammatory actions of DEX. The treatment of macrophages with either DEX or acidic pH induced the cell death of macrophages; however, the cell death was not affected by TDAG8 deficiency. While DEX inhibited lipopolysaccharide-induced production of tumor necrosis factor-{alpha}, an inflammatory cytokine, which was independent of TDAG8, at neutral pH, the glucocorticoid enhanced the acidic pH-induced inhibition of tumor necrosis factor-{alpha} production in a manner dependent on TDAG8. In conclusion, the DEX-induced increase in TDAG8 expression is in part involved in the glucocorticoid-induced anti-inflammatory actions through the inhibition of inflammatory cytokine production under the acidic pH environment. On the other hand, the role of TDAG8 in the DEX-induced cell death is questionable.

    The Oceans of Opportunity program to increase involvement of traditionally under-represented students in the marine geosciences is in its final phase of track 1 funding from NSF. The program employs a tiered approach to research, teaching and outreach activities to enhance the K-12 to graduate pipeline. Partner institutions include Savannah State University, an HBCU in coastal Georgia; Adelphi University serving a minority population from NYC; the Georgia State University Bio-Bus serving the metro-Atlanta area; and the Joint Oceanographic Institutions. The Oceans of Opportunity education pipeline includes 1) service learning activities implemented by SSU marine science majors in partner public schools with high minority enrollment; 2) outreach by the Georgia State University Bio-Bus to Savannah area schools; 3) expansion of the SSU geoscience curriculum; and 4) development of activities based on models of ODP cores for use in both outreach and college teaching. Service learning through SSU classes has permitted contact with a large number of K-12 students. More than 1000 predominantly African-American K-12 students completed hands-on lessons on plate tectonics and plankton contributors to marine sediments in the two years of this program under the guidance of HBCU science majors. Lessons on use of the marine sediment and fossil record as proxies in paleoclimatic studies using replicas of ODP cores were delivered to 600 students in the Savannah school system and about 2000 visitors to the Georgia Aquarium in Atlanta. The marine geoscience lessons delivered at the high school level resulted in greater test score improvement when the topic had already been thoroughly introduced by the teacher. A survey of science attitudes of the high school students (n=419) indicates African-American high school students have low levels of enjoyment of and interest in the sciences. In addition, more female than male African-American students are enrolling in science courses and

    2013-02-01

    Transforming growth factor β1 (TGF-β1) is a pleiotropic cytokine that modulates cell homeostasis. In Leydig cells, TGF-β1 exerts stimulatory and inhibitory effect depending on the type I receptor involved in the signaling pathway. The aim of the present work was to study the signaling mechanisms and the intermediates involved in the action of TGF-β1 on TM3 Leydig cell proliferation in the presence or absence of progesterone. The MTT assay showed that the presence of progesterone in the culture media lead to a proliferative effect that was blocked by Ru 486, an inhibitor of progesterone receptor; and ALK-5 did not participate in this effect. TGF-β1 (1 ng/ml) increased the expression of p15 (an inhibitor of cell cycle) in TM3 Leydig cells, and this effect was blocked by progesterone (1μM). The expression of PCNA presented a higher increase in the cell cultured with TGF-β1 plus progesterone than in cells cultured only with TGF-β1. Progesterone induced the gene expression of endoglin, a cofactor of TGF-β1 receptor that leads to a stimulatory signaling pathway, despite of the absence of progesterone response element in endoglin gene. In addition, the presence of progesterone induced the gene expression of egr-1 and also KLF14, indicating that this steroid channels the signaling pathway into a non-canonical mechanism. In conclusion, these findings suggest that the proliferative action of TGF-β1 involves endoglin. This co-receptor might be induced by KLF14 which is probably activated by progesterone. PMID:23317878

  14. Restraints to reform: The congruence of teacher and student actions in a chemistry classroom

    McRobbie, Campbell; Tobin, Kenneth

    An interpretive methodology was employed to examine interrelations between teacher and student actions in a context of teaching and learning in an urban high school in Australia, a teacher of 20 years' experience, and a Grade 11 chemistry class. Data sources included teacher and student interviews, direct observation and videotapes of 4 weeks of lessons, and responses to a classroom environment survey. Three narratives were constructed for a typical lesson, the perspectives of the teacher, and the perspectives of a composite student. These narratives were used to describe what happened and communicate what we learned from the study. Initially, the teacher and students had difficulty describing their beliefs; however, as the study progressed they used language to describe their practices and construct mental models that fit with their practices and beliefs about learning. Teacher and student goals, beliefs about teacher and learner roles, and constructions of the context were coherent to such an extent that there was little impetus for change. These findings are discussed in terms of the difficulties of initiating and sustaining reform when the teacher and students are satisfied with what is happening and other sociocultural factors tend to support the status quo.Received: 26 April 1994; Revised: 8 September 1994;

    Clevenson, Rhonda Suzanne

    This research examined the responses of families to bilingual communication methods, text versus video, designed to facilitate school to home communication to increase parent involvement and seventh grade student achievement in the science fair project. Using an experimental design, 161 families were randomly selected to receive either a two part informational text or video series during the science fair unit taught at a culturally diverse urban middle school. The bilingual informational materials were created and produced by the staff at the research site. Measures were taken to make sure all families could access the informational materials and innovations such as a special travel envelope and reminding procedures aided data collection. Surveys measuring variables on a Likert scale with spaces for comments were collected from the parents and students. An interrater reliability study was completed to measure the agreement of the two teachers who used a grading checklist to score science fair project achievement. Quantitative methods including ANOVA and MLR were used to examine the data in terms of student achievement and the communication method (text or video), audience (students and parents), and the anticipated outcome (parent help). Nonparametric and qualitative data analyses were used to explore how families used and responded to the informational materials. Significant results were that the video communication method was positively associated with student achievement on the science fair project. Significant main effects were observed for the student characteristics, educational services (general and special education, and English as a Second Language), and previous achievement in science, and the parent characteristics, previous experience with science fair projects, primary viewing language (English or Spanish), and expectations for student achievement. Student achievement was not significantly related to the amount or usefulness of parent help. The amount

  17. A phenomenographic analysis of first-year engineering students' experiences with problems involving multiple possible solutions

    NASA Astrophysics Data System (ADS)

    Dringenberg, Emily A.

    Engineers are expected to solve problems that are ill-structured. These problems are presented with a lack of necessary information and allow for different ways of engaging with the problem; they are open-ended and involve multiple possible solutions with multiple means of evaluation. In order to allow maximum time for students to develop skills for solving such problems, undergraduate engineering programs can introduce such problems during the first year of students' education, in the form of cornerstone design tasks. This provides students with more opportunities to develop their ability to engage with ill-structured problems, which are characteristic of engineering work. Researchers have documented variation within both the behavior and perceptions of students' early experiences with design problems. General themes include novice-like design behavior, discomfort with lack of information, difficulty with problem scoping, and resistance to ambiguity. To build on these generalizations of students' experiences, a more thorough understanding of the variation in how students experience this phenomenon of engaging with ill-structured problems is needed to design effective learning environments. This work presents the qualitatively different ways that engineering students experience problems with multiple possible solutions during their first year of engineering studies. Using phenomenography as the methodological framework, data were collected through in-depth, semi-structured interviews with 27 first-year engineering students. The iterative, phenomenographic analysis resulted in seven descriptive categories for the ways participants experienced problems involving multiple possible solutions. The names of these categories represent the different foci of the students' experiences: completion, transition, iteration, organization, collaboration, reasoning, and growth. These categories are organized along two crucial dimensions of variation: reaction to ambiguity and role

    Intrinsic electrical activities in various isolated segments of the mouse small intestine were recorded (i) to characterize action potential generation and (ii) to obtain a profile on the ion channels involved in initiating the slow wave type action potentials (slow waves). Gradients in slow wave frequency, resting membrane potential, and occurrence of spiking activity were found, with the proximal intestine exhibiting the highest frequency, the most hyperpolarized cell membrane, and the greatest occurrence of spikes. The slow waves were only partially sensitive to L-type calcium channel blockers. Nifedipine, verapamil, and pinaverium bromide abolished spikes that occurred on the plateau phase of the slow waves in all tissues. The activity that remained in the presence of L-type calcium channel blockers, the upstroke potential, retained a similar amplitude to the original slow wave and was of identical frequency. The upstroke potential was not sensitive to a reduction in extracellular chloride or to the sodium channel blockers tetrodotoxin and mexiletine. Abolishment of the Na+ gradient by removal of 120 mM extracellular Na+ reduced the upstroke potential frequency by 13 - 18% and its amplitude by 50 - 70% in the ileum. The amplitude was similarly reduced by Ni2+ (up to 5 mM), and by flufenamic acid (100 mu M), a nonspecific cation and chloride channel blocker. Gadolinium, a nonspecific blocker of cation and stretch-activated channels, had no effect. Throughout these pharmacological manipulations, a robust oscillation remained at 5 - 10 mV. This oscillation likely reflects pacemaker activity. It was rapidly abolished by removal of extracellular calcium but not affected by L-type calcium channel blockers. In summary, the mouse small intestine has been established as a model for research into slow wave generation and electrical pacemaker activity. The upstroke part of the slow wave has two components, the pacemaker component involves a non-L-type calcium channel

    Barnard College and Columbia University's Center for New Media Teaching and Learning's Brownfield Action is a digital web-based, interactive simulation that combines lecture, laboratory exercises, and individual and collaborative out-of-classroom assignments. The objective of the instruction is to locate and define a subsurface plume of gasoline whose point source is a leaking underground storage tank (LUST) at a gas station. In the fall of 2009, fifteen pre-college high school students from the five boroughs of New York City used Brownfield Action in a 12-week after-school enrichment program at Barnard to investigate the gasoline plume using a variety of geophysical methods - excavation, ground penetrating radar, magnetic metal detection, soil gas, and drilling. The investigation resulted in individual Phase One Site Assessment Reports about the LUST. As coordinators and instructors of the program, we will share our experience teaching the students and the advantages and challenges of using a digital simulation as an instructional centerpiece. Such instruction is intended to include civic engagement and responsibility as part of science education and to create a curriculum that, instead of relying on fragmented and abstract instruction, provides students with a realistic, inquiry-based, and interdisciplinary construction of knowledge.

    In goldfish, two endogenous gonadotrophin-releasing hormones (GnRHs) [salmon (s)GnRH and chicken (c)GnRH-II] control maturational gonadotrophin-II [lutenising hormone (LH)] and growth hormone (GH) secretion via Ca(2+)-dependent intracellular signalling pathways. We investigated the involvement of phosphoinositide 3-kinase (PI3K) in GnRH-evoked LH and GH release and associated intracellular Ca(2+) increases ([Ca(2+)](i) ) in goldfish gonadotrophs and somatotrophs. Immunoreactive PI3K p85α, the predominant regulatory subunit for class IA PI3Ks, was detected in goldfish pituitary tissue extracts and both endogenous GnRH isoforms increased phosphorylation of PI3K p85α in excised pituitary fragments. sGnRH- and cGnRH-II-elicited LH release responses from primary cultures of pituitary cells and [Ca(2+)](i) increases in identified gonadotrophs were significantly reduced in the presence of PI3K inhibitors wortmannin (100 nm) and LY294002 (10 μm). Unexpectedly, wortmannin and LY294002 inhibited GnRH-evoked GH release but only attenuated the [Ca(2+)](i) response in identified somatotrophs to cGnRH-II, and not sGnRH. On the other hand, Ca(2+) ionophore-evoked LH and GH secretion remained unaltered in the presence of the PI3K inhibitors, suggesting that general decreases in the releasable hormone pool or sensitivity to [Ca(2+)](i) changes did not underlie the ability of wortmannin and LY294002 to reduce the actions of GnRH. These results provide the first evidence for the presence and involvement of PI3K in GnRH-induced LH and GH release in any primary pituitary cell system. In gonadotrophs, the inhibitory action of PI3K on both sGnRH and cGnRH-II involves the attenuation of their evoked [Ca(2+)](i); in contrast, GnRH isoform-specific effects occur in somatotrophs.

    To memorialize the anniversary of the 1976 Friuli earthquake, the Istituto Statale di Istruzione Superiore "Magrini Marchetti" in Gemona del Friuli (NE Italy), with the collaboration of the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS), has promoted the PRESS40 Project (Prevenzione Sismica nella Scuola a 40 anni dal terremoto del Friuli, that in English sounds like "Seismic Prevention at School 40 years later the Friuli earthquake"). The project has developed in the 2015-2016 school year, starting from the 40th anniversary of the Friuli earthquake, and it aims to disseminate historical memory, seismic culture and awareness of seismic safety in the young generations, too often unconscious of past experiences, as recent seismic hazard perception tests have demonstrated. The basic idea of the PRESS40 Project is to involve the students in experimental activities to be active part of the seismic mitigation process. The Project is divided into two main parts, the first one in which students learn-receive knowledge from researchers, and the second one in which they teach-bring knowledge to younger students. In the first part of the project, 75 students of the "Magrini Marchetti" school acquired new geophysical data, covering the 23 municipalities from which they come from. These municipalities represent a wide area affected by the 1976 Friuli earthquake. In each locality a significant site was examined, represented by a school area. At least, 127 measurements of ambient noise have been acquired. Data processing and interpretation of all the results are still going on, under the supervision of OGS researchers.The second part of the project is planned for the early spring, when the students will present the results of geophysical survey to the younger ones of the monitored schools and to the citizens in occasion of events to commemorate the 40th anniversary of the Friuli earthquake.

    2009-01-01

    This study used latent growth curve modeling to investigate whether the effects of gender and Greek involvement on alcohol use and problems over the first 2 years of college are best characterized by selection, socialization, or reciprocal influence processes. Three social influences (alcohol offers, social modeling, and perceived norms) were examined as potential mediators of these effects. Undergraduate participants (N = 388) completed self-report measures prior to enrollment and in the spring of their freshmen and sophomore years. Male gender and involvement in the Greek system were associated with greater alcohol use and problems prior to college. Both gender and Greek involvement significantly predicted increases in alcohol use and problems over the first 2 years of college. Cross-domain analyses provided strong support for a mediational role of each of the social influence constructs on alcohol use and problems prior to matriculation, and prematriculation social modeling and alcohol offers mediated relations between Greek involvement and changes in alcohol use over time. Findings suggest that students, particularly men, who affiliate with Greek organizations constitute an at-risk group prior to entering college, suggesting the need for selected interventions with this population, which should take place before or during the pledging process.

    Background The treatment for leishmaniasis is currently based on pentavalent antimonials and amphotericin B; however, these drugs result in numerous adverse side effects. The lack of affordable therapy has necessitated the urgent development of new drugs that are efficacious, safe, and more accessible to patients. Natural products are a major source for the discovery of new and selective molecules for neglected diseases. In this paper, we evaluated the effect of apigenin on Leishmania amazonensis in vitro and in vivo and described the mechanism of action against intracellular amastigotes of L. amazonensis. Methodology/Principal Finding Apigenin reduced the infection index in a dose-dependent manner, with IC50 values of 4.3 μM and a selectivity index of 18.2. Apigenin induced ROS production in the L. amazonensis-infected macrophage, and the effects were reversed by NAC and GSH. Additionally, apigenin induced an increase in the number of macrophages autophagosomes after the infection, surrounding the parasitophorous vacuole, suggestive of the involvement of host autophagy probably due to ROS generation induced by apigenin. Furthermore, apigenin treatment was also effective in vivo, demonstrating oral bioavailability and reduced parasitic loads without altering serological toxicity markers. Conclusions/Significance In conclusion, our study suggests that apigenin exhibits leishmanicidal effects against L. amazonensis-infected macrophages. ROS production, as part of the mechanism of action, could occur through the increase in host autophagy and thereby promoting parasite death. Furthermore, our data suggest that apigenin is effective in the treatment of L. amazonensis-infected BALB/c mice by oral administration, without altering serological toxicity markers. The selective in vitro activity of apigenin, together with excellent theoretical predictions of oral availability, clear decreases in parasite load and lesion size, and no observed compromises to the overall health

  15. Mechanism of action of peptidoglycan O-acetyltransferase B involves a Ser-His-Asp catalytic triad.

    Moynihan, Patrick J; Clarke, Anthony J

    2014-10-01

    The O-acetylation of the essential cell wall polymer peptidoglycan is essential in many bacteria for their integrity and survival, and it is catalyzed by peptidoglycan O-acetlytransferase B (PatB). Using PatB from Neisseria gonorrhoeae as the model, we have shown previously that the enzyme has specificity for polymeric muropeptides that possess tri- and tetrapeptide stems and that rates of reaction increase with increasing degrees of polymerization. Here, we present the catalytic mechanism of action of PatB, the first to be described for an O-acetyltransferase of any bacterial exopolysaccharide. The influence of pH on PatB activity was investigated, and pKa values of 6.4-6.45 and 6.25-6.35 for the enzyme-substrate complex (kcat vs pH) and the free enzyme (kcat·KM(-1) vs pH), respectively, were determined for the respective cosubstrates. The enzyme is partially inactivated by sulfonyl fluorides but not by EDTA, suggesting the participation of a serine residue in its catalytic mechanism. Alignment of the known and hypothetical PatB amino acid sequences identified Ser133, Asp302, and His305 as three invariant amino acid residues that could potentially serve as a catalytic triad. Replacement of Asp302 with Ala resulted in an enzyme with less than 20% residual activity, whereas activity was barely detectable with (His305 → Ala)PatB and (Ser133 → Ala)PatB was totally inactive. The reaction intermediate of the transferase reaction involving acetyl- and propionyl-acyl donors was trapped on both the wild-type and (Asp302 → Ala) enzymes and LC-MS/MS analysis of tryptic peptides identified Ser133 as the catalytic nucleophile. A transacetylase mechanism is proposed based on the mechanism of action of serine esterases. PMID:25215566

  16. Possible involvement of K+-conductance in the action of gamma-aminobutyric acid in the guinea-pig hippocampus.

    Inoue, M.; Matsuo, T.; Ogata, N.

    1985-01-01

    The mechanism underlying the action of gamma-aminobutyric acid (GABA) in the hippocampus was investigated using guinea-pig brain slices. GABA either superfused or applied directly by microiontophoresis produced a biphasic response in pyramidal cells, comprising hyperpolarizing and depolarizing components. When different concentrations of GABA were applied to the same neurone, the lower concentrations generally produced a hyperpolarization-predominant response, while higher concentrations resulted in a depolarization-predominant response. The depolarizing component of the response to GABA was augmented in a medium containing a low concentration of Cl-, relatively unaffected by a change in external K+ concentration, and blocked by picrotoxin (2 X 10(-5) M). The depolarizing response to GABA persisted in a Ca2+-free medium in which the concentration of Na+ was reduced to 13 mM. Combined application of low doses of picrotoxin and bicuculline eliminated the major part of the depolarizing component of the biphasic response to GABA and produced a relatively pure hyperpolarizing response. The reversal potential of this pharmacologically 'isolated' hyperpolarizing response to GABA was estimated, from the current-voltage relationships, to be about -90 mV and was the same as that of the hyperpolarization induced by baclofen. When the membrane was successively hyperpolarized by inward direct current (d.c.) injections, the reversal point of the 'pharmacologically isolated' hyperpolarizing response to GABA coincided with that of the post-burst hyperpolarization. Low concentrations of Cl- in the bathing medium had no noticeable effect on the hyperpolarizing component of the response to GABA, whereas it markedly increased the amplitude of the depolarizing component. These results suggest that the action of GABA in the hippocampus may involve an activation of K+ conductance. PMID:2413946

    There are about 1.8 million young immigrants in the United States who came or were brought to the country without documentation before the age of 16. These youth have been raised and educated in the United States and have aspirations and educational achievements similar to those of their native-born peers. However, their undocumented status has hindered their pursuit of higher education, especially in medical and other graduate health sciences. Under a new discretionary policy, Deferred Action for Childhood Arrivals (DACA), many of these young immigrants are eligible to receive permission to reside and work in the United States. DACA defers deportation of eligible, undocumented youth and grants lawful presence in the United States, work permits, Social Security numbers, and, in most states, driver's licenses. These privileges have diminished the barriers undocumented students traditionally have faced in obtaining higher education, specifically in pursuing medicine. With the advent of DACA, students are slowly matriculating into U.S. medical schools and residencies. However, this applicant pool remains largely untapped. In the face of a physician shortage and the implementation of the Affordable Care Act, an increase in matriculation of qualified undocumented students would be greatly beneficial. This Perspective is intended to begin discussion within the academic medicine community of the implications of DACA in reducing barriers for the selection and matriculation of undocumented medical students and residents. Moreover, this Perspective is a call to peers in the medical community to support undocumented students seeking access to medical school, residency, and other health professions. PMID:25093382

  6. The use of parent involved take-home science activities during student teaching: Understanding the challenges of implementation

    NASA Astrophysics Data System (ADS)

    Zarazinski, Jill

    The purpose of this study was to identify student teachers use and implementation of Science in a Bag when it was no longer a required course-based assessment. This take-home science activity acted as the elaboration component of the 5Es lesson teacher candidates designed and taught in the classroom, utilized household items, and directly involved parents in their child's education. The purposeful sample was comprised of six teacher candidates during their student teaching practicum, the last semester of the childhood education teacher certification program. This collective case study centered on student teachers' use of the focused activity, Science in a Bag, in order to gain knowledge of challenges faced in applying take-home science kits and working with parents. Data collection was comprised of student teacher and parent interviews, candidate reflections, as well as in-class observations and discussions carried out during weekly seminars. Data collection occurred throughout the seven-week student teaching practicum. The four research questions were: 1) What factors do teacher candidates identify as interfering with their ability to implement Science in a Bag during student teaching placements? 2) What factors do teacher candidates identify as enhancing their ability to carry out Science in a Bag? 3) What forms of support do teacher candidates believe are important to their success in implementing Science in a Bag during student teaching? 4) How do teacher candidates deal with obstacles when implementing Science in a Bag? Despite the fact that no student teacher was prohibited from implementing Science in a Bag, the level to which candidates valued and utilized this instructional strategy varied compared to how they were taught and practiced it during the science methods course. Some student teachers attempted to hide their feelings toward Science in a Bag, however their actions revealed that they were simply carrying out the instructional strategy because they

  8. The academic differences between students involved in school-based robotics programs and students not involved in school-based robotics programs

    NASA Astrophysics Data System (ADS)

    Koumoullos, Michael

    This research study aimed to identify any correlation between participation in afterschool robotics at the high school level and academic performance. Through a sample of N=121 students, the researcher examined the grades and attendance of students who participated in a robotics program in the 2011-2012 school year. The academic record of these students was compared to a group of students who were members of school based sports teams and to a group of students who were not part of either of the first two groups. Academic record was defined as overall GPA, English grade, mathematics grade, mathematics-based standardized state exam scores, and attendance rates. All of the participants of this study were students in a large, urban career and technical education high school. As STEM (Science, Technology, Engineering, and Mathematics) has come to the forefront of educational focus, robotics programs have grown in quantity. Starting robotics programs requires a serious commitment of time, money, and other resources. The benefits of such programs have not been well analyzed. This research study had three major goals: to identify the academic characteristics of students who are drawn to robotics programs, to identify the academic impact of the robotics program during the robotics season, and to identify the academic impact of the robotics program at the end of the school year. The study was a non-experiment. The researchers ran MANOVS, repeated measures analyses, an ANOVA, and descriptive statistics to analyze the data. The data showed that students drawn to robotics were academically stronger than students who did not participate in robotics. The data also showed that grades and attendance did not significantly improve or degrade either during the robotics season or at year-end. These findings are significant because they show that robotics programs attract students who are academically strong. This information can be very useful in high school articulation programs

    The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), developed by the World Health Organization (WHO), has been used successfully in many countries, but there are few studies of its validity and reliability for the Mexican population. The objective of this study was to determine the psychometric properties of the self-administered ASSIST test in university students in Mexico. This was an ex post facto non-experimental study with 1,176 undergraduate students, the majority women (70.1%) aged 18-23 years (89.5%) and single (87.5%). To estimate concurrent validity, factor analysis and tests of reliability and correlation were carried out between the subscale for alcohol and AUDIT, those for tobacco and the Fagerström Test, and those for marijuana and DAST-20. Adequate reliability coefficients were obtained for ASSIST subscales for tobacco (alpha = 0.83), alcohol (alpha = 0.76), and marijuana (alpha = 0.73). Significant correlations were found only with the AUDIT (r = 0.71) and the alcohol subscale. The best balance of sensitivity and specificity of the alcohol subscale (83.8% and 80%, respectively) and the largest area under the ROC curve (81.9%) was found with a cutoff score of 8. The self-administered version of ASSIST is a valid screening instrument to identify at-risk cases due to substance use in this population. PMID:26990386

    This study aimed to investigate the involvement of opioid receptors in the systemic and peripheral antinociceptive activities of montelukast in different animal models of pain. Rats and mice were injected with montelukast to produce analgesia. The formalin and acetic acid-induced writhing tests were used to assess the nociceptive activity. The results showed that i.p. administration of montelukast (0.3-10mg/kg) dose-dependently reduced flinching behavior in both the first and second phases of formalin test with mean ED50 of 0.55 and 5.31mg/kg, respectively. Also, intraplantar administration of montelukast (3-30μg/paw) produced antinociception against the two phases of formalin assay in a dose-dependent way with mean ED30 of 2.92 and 8.11μg/paw, respectively. Furthermore, pre-treatment with naloxone (a non-selective opioid receptor antagonist) significantly inhibited both the systemic and also peripheral antinociceptive actions of montelukast in formalin test. In writhing test, the results showed that intraperitoneal administration of montelukast (3-10mg/kg) significantly reduced the writhe number induced by acetic acid in mice. Moreover, co-administration of non-effective doses of montelukast (0.3 and 1mg/kg; i.p.) and morphine (0.25mg/kg; i.p.) significantly decreased the writhes number induced by acetic acid. Also, this effect was naloxone-reversible. These findings suggest that the systemic and peripheral antinociception produced by montelukast were mediated through the opioid receptors in central and peripheral nervous systems. Moreover, combination of montelukast and morphine could be noted as a new strategy for pain relief. PMID:26948314

    2009-12-01

    In the course of research programs to develop a methodology for the study of microtopography of ice and snow surfaces, we placed a strong emphasis on the involvement of students. This project provided the opportunity to engage students in every step from building the instrument through development of the data processing, the actual field measurements, processing of the resultant data, their evaluation and interpretation to the final publication in scientific journals. The development of the Glacier Roughness Sensor (GRS) incorporating Global Positioning System (GPS) technology and the fieldwork on the Greenland Inland Ice were particularly fascinating and instructive for students. In a related snow-hydrological research project on Niwot Ridge in the Colorado Front Range, we involved students in two season-long measurement campaigns in a high alpine environment. Students from the Universität Trier, Germany, and the University of Colorado Boulder participated in this project to learn about the value of international collaboration in science. Funding was provided by Deutsche Forschungsgemeinschaft (Antarctic and Arctic Program) and the U.S. National Science Foundation (Hydrological Sciences Program). Students participated in preparatory classes and field camps, selected their own research projects and received university credit towards their degrees in geography or environmental sciences. All student participants in the MICROTOP projects have gone on to higher university education and become professionally exceptionally successful.
