  13. Active magnetoplasmonic ruler (Conference Presentation)

    NASA Astrophysics Data System (ADS)

    Zubritskaya, Irina

    2016-04-01

    Plasmon rulers are an emerging concept in which the strong near-field coupling of plasmon nanoantenna elements is employed to obtain structural information at the nanoscale. Here, we combine nanoplasmonics and nanomagnetism to conceptualize a magnetoplasmonic dimer nanoantenna that would be able to report nanoscale distances while optimizing its own spatial orientation. The latter constitutes an active operation in which a dynamically optimized optical response per measured unit length allows for the measurement of small and large nanoscale distances with about 2 orders of magnitude higher precision than current state-of-the-art plasmon rulers. We further propose a concept to optically measure the nanoscale response to the controlled application of force with a magnetic field.

  8. Attachment relationships and physical activity motivation of college students.

    PubMed

    Ullrich-French, Sarah; Smith, Alan L; Cox, Anne E

    2011-08-01

    This study was designed to assess the link of attachment relationships with physical activity motivation. Potential mediators of this link were examined in a cross-sectional study targeting college student physical activity motivation and behaviour. Participants completed self-reports of attachment relationships (with mother, father and best friend), self-determined motivation for physical activity, physical activity behaviour and the hypothesised mediator variables of perceived competence, autonomy and relatedness. The results provide support for the mediating role of these variables in the association of father attachment with self-determined motivation. Meaningful variance in self-determined motivation for physical activity and physical activity behaviour was explained. Overall, attachment relationships appear to be relevant, albeit modestly, to physical activity motivation of college students. The findings support continued efforts to integrate attachment and motivational perspectives in the study of college student health behaviour.

  10. Auxin Activity: Past, present, and Future1

    PubMed Central

    Enders, Tara A.; Strader, Lucia C.

    2016-01-01

    Long before its chemical identity was known, the phytohormone auxin was postulated to regulate plant growth. In the late 1800s, Sachs hypothesized that plant growth regulators, present in small amounts, move differentially throughout the plant to regulate growth. Concurrently, Charles Darwin and Francis Darwin were discovering that light and gravity were perceived by the tips of shoots and roots and that the stimulus was transmitted to other tissues, which underwent a growth response. These ideas were improved upon by Boysen-Jensen and Paál and were later developed into the Cholodny–Went hypothesis that tropisms were caused by the asymmetric distribution of a growth-promoting substance. These observations led to many efforts to identify this elusive growth-promoting substance, which we now know as auxin. In this review of auxin field advances over the past century, we start with a seminal paper by Kenneth Thimann and Charles Schneider titled “The relative activities of different auxins” from the American Journal of Botany, in which they compare the growth altering properties of several auxinic compounds. From this point, we explore the modern molecular understanding of auxin—including its biosynthesis, transport, and perception. Finally, we end this review with a discussion of outstanding questions and future directions in the auxin field. Over the past 100 yr, much of our progress in understanding auxin biology has relied on the steady and collective advance of the field of auxin researchers; we expect that the next 100 yr of auxin research will likewise make many exciting advances.

  14. Daily activities and sleep quality in college students.

    PubMed

    Carney, Colleen E; Edinger, Jack D; Meyer, Björn; Lindman, Linda; Istre, Tai

    2006-01-01

    There is growing evidence that social rhythms (e.g., daily activities such as getting into or out of bed, eating, and adhering to a work schedule) have important implications for sleep. The present study used a prospective measure of daily activities to assess the relation between sleep and social rhythms. College students (n=243) 18 to 39 yrs of age, completed the Social Rhythm Metric (SRM) each day for 14 d and then completed the Pittsburgh Sleep Quality Index (PSQI). The sample was divided into groups of good or poor sleepers, according to a PSQI cut-off score of 5 points and was compared on the regularity, frequency, timing, and extent of social engagement during activities. There was a lower frequency and less regularity of social rhythms in poor sleepers relative to good sleepers. Good sleepers engaged more regularly in activities with active social engagement. Earlier rise time, first consumption of a beverage, going outdoors for the first time, and bedtime were associated with better sleep. Greater variability in rise time, consuming a morning beverage, returning home for the last time, and bedtime were associated with more disturbed sleep. The results are consistent with previous findings of reduced regularity in bedtime and rise time schedules in undergraduates, other age groups, and in clinical populations. Results augment the current thought that regulating behavioral zeitgebers may be important in influencing bed and rise times, and suggest that engaging in activities with other people may increase regularity.

    PubMed

    Martínez, Cristina; Prieto, Amador; García, Laura; Quero, Aida; González, Susana; Casan, Pere

    2010-02-01

    Silicosis, an interstitial lung disease caused by the inhalation of crystalline silica powder, despite being one of the oldest occupational diseases, continues being a cause of morbidity and mortality all over the world. The World Health Organisation and the International Labour Organisation (OMS/ILO), aware of the current problem, have designed the World Programme for the Elimination of Silicosis, which includes the identification of occupational groups at risk amongst its actions. We present 3 cases of silicosis in young workers in the construction sector, with exposure to high concentrations of silica due to handling artificial silica conglomerates. The main interest of this observation lies in the identification of new risk sources, in the need to draw attention to the dangers involved in its use without prevention measures, and in the importance of the occupational history to avoid under-diagnosis.

  5. Active Learning Not Associated with Student Learning in a Random Sample of College Biology Courses

    PubMed Central

    Andrews, T. M.; Leonard, M. J.; Colgrove, C. A.; Kalinowski, S. T.

    2011-01-01

    Previous research has suggested that adding active learning to traditional college science lectures substantially improves student learning. However, this research predominantly studied courses taught by science education researchers, who are likely to have exceptional teaching expertise. The present study investigated introductory biology courses randomly selected from a list of prominent colleges and universities to include instructors representing a broader population. We examined the relationship between active learning and student learning in the subject area of natural selection. We found no association between student learning gains and the use of active-learning instruction. Although active learning has the potential to substantially improve student learning, this research suggests that active learning, as used by typical college biology instructors, is not associated with greater learning gains. We contend that most instructors lack the rich and nuanced understanding of teaching and learning that science education researchers have developed. Therefore, active learning as designed and implemented by typical college biology instructors may superficially resemble active learning used by education researchers, but lacks the constructivist elements necessary for improving learning.

    PubMed Central

    2012-01-01

    The Asian College of Psychosomatic Medicine (ACPM) was founded as the Asian Chapter of the International College of Psychosomatic Medicine (ICPM-AC) in Tokyo on April 12, 1982. The first president was Hitoshi ISHIKAWA (Japan), the vice-presidents were Mahalingam MAHADEVAN (Malaysia) and Burton G.BURTON-BRADLEY (Papua- New Guinea), and the general secretary was Sueharu TSUTSUI (Japan). Five years previously, preparation for creation of the ICPM-AC was started at the 4th World Congress of the International College of Psychosomatic Medicine (ICPM) held in Kyoto, Japan, September 5-9, 1977. The First Congress of the ICPM-AC was held by the President Yujiro IKEMI in Tokyo on May 19-20, 1984. The main members in the early stage were Y. IKEMI, H. ISHIKAWA, S. TSUTSUI, Taisaku KATSURA, Tetsuya NAKAGAWA. Hiroyuki SUEMATSU and others from Japan and Hsien RIN (Taiwan), Seock Young KANG (Korea), M. MAHADEVAN. B.G. BURTON-BRADLEY and others from other Asian countries. Thereafter, academic congresses of the ICPM-AC, the 2nd to the 9th, were held approximately every two years, in Japan, India, Malaysia, Taiwan, Korea, and China. The name was changed to the Asian College of Psychosomatic Medicine (ACPM), and the 10th to 14th congresses were held in Taiwan, Okinawa (Japan), Australia, Korea, and China. The current president of the Executive Board of ACPM is Chiharu KUBO, the Director of Kyushu University Hospital.

  17. Projected Alcohol Dose Influences on the Activation of Alcohol Expectancies in College Drinkers

    PubMed Central

    Read, Jennifer P.; Lau-Barraco, Cathy; Dunn, Michael E.; Borsari, Brian

    2009-01-01

    Background Alcohol expectancies have been linked to drinking behavior in college students, and vary according to a number of factors, including projected dose of alcohol. Research using Multidimensional Scaling (MDS) suggests that drinking may be influenced by activation of differing expectancy dimensions in memory, yet studies have not examined expectancy activation according to projected alcohol doses. Methods The present study used Individual Differences Scaling (INDSCAL) to map expectancy networks of college students (n = 334) who imagined varied drinking at high and low alcohol doses. Expectancy activation was modeled by dose, as well as by gender and by drinking patterns (typical quantity, blood alcohol content, heavy episodic drinking, and alcohol consequences). Expectancies were organized along positive-negative and arousal-sedation dimensions. Anticipation of a high dose of alcohol was associated with greater emphasis on the arousal-sedation dimension, whereas anticipation of a lower dose was associated with greater emphasis on the positive-negative dimension. Results Across heavy, medium, and light drinkers, expectancy dimensions were most distinguishable at higher doses; activation patterns were more similar across drinking groups at lighter doses. Modest evidence for the influence of gender on activation patterns was observed. Findings were consistent across alcohol involvement indices. Conclusions These data suggest that both dimensionality and context should be considered in the refinement of interventions designed to alter expectancies in order to decrease hazardous drinking.

  20. Integration of the brief behavioral activation treatment for depression (BATD) into a college orientation program: depression and alcohol outcomes.

    PubMed

    Reynolds, Elizabeth K; Macpherson, Laura; Tull, Matthew T; Baruch, David E; Lejuez, C W

    2011-10-01

    College freshmen face a variety of academic and social challenges as they adjust to college life that can place them at risk for a number of negative outcomes, including depression and alcohol-related problems. Orientation classes that focus on teaching incoming students how to better cope with college-oriented stress may provide an opportunity to prevent the development of these adjustment problems. This article outlines a program based on behavioral activation that can be integrated into college orientation programs to provide a more comprehensive orientation experience. Data are presented from an initial pilot study in which 71 first-semester freshman at the University of Maryland participated in a 15-week, 2 hr per week orientation class (n = 37 in the behavioral activation-enhanced orientation classes and n = 34 in the control orientation as usual classes). Students' depression and alcohol use were evaluated at the beginning, middle, and end of the course. Results indicated a Time × Group interaction such that problem drinking (but not consumption) was significantly reduced across assessments in the behavioral activation classes and largely unchanged in the standard classes. No difference was observed in depression scores; however, fairly low depression scores across the 3 time points may have limited the opportunity to observe any meaningful impact of the orientation classes on depression. The authors conclude with a discussion of the implications of their findings for preventing adjustment problems among incoming college students and future directions.

  1. Biological Activities of Phenolic Compounds Present in Virgin Olive Oil

    Cicerale, Sara; Lucas, Lisa; Keast, Russell

    2010-01-01

    The Mediterranean diet is associated with a lower incidence of atherosclerosis, cardiovascular disease, neurodegenerative diseases and certain types of cancer. The apparent health benefits have been partially ascribed to the dietary consumption of virgin olive oil by Mediterranean populations. Much research has focused on the biologically active phenolic compounds naturally present in virgin olive oils to aid in explaining reduced mortality and morbidity experienced by people consuming a traditional Mediterranean diet. Studies (human, animal, in vivo and in vitro) have demonstrated that olive oil phenolic compounds have positive effects on certain physiological parameters, such as plasma lipoproteins, oxidative damage, inflammatory markers, platelet and cellular function, antimicrobial activity and bone health. This paper summarizes current knowledge on the bioavailability and biological activities of olive oil phenolic compounds. PMID:20386648

    Seo, Dong-Chul; Torabi, Mohammad R; Jiang, Nan; Fernandez-Rojas, Xinia; Park, Bock-Hee

    2009-10-01

    This study examined cross-cultural differences in personal and behavioral determinants of vigorous-intensity and moderate-intensity physical activity (PA) among college students living in distinctly different cultures, that is, the United States, Costa Rica, India, and South Korea. Participants of this study were recruited from randomly chosen public universities in the 4 countries during the 2006-2007 academic year. A total of 4685 students participated in the study (response rate 90%). Vigorous-intensity PA was measured by asking on how many of the past 7 days the participants participated in PA for at least 20 minutes that made them sweat or breathe hard. For moderate-intensity PA, participants were asked on how many of the past 7 days they participated in PA for at least 30 minutes that did not make them sweat or breathe hard. Findings indicate that whereas perceived overweight and fruit and vegetable consumption are relatively culture-free predictors of PA, gender and TV/video watching are culture-specific predictors. Binge drinking was not predictive of meeting the vigorous-intensity and moderate-intensity PA guidelines in any of the 4 countries. PMID:19661101

    2014-03-01

    The present study asses the prevalence of depressive symptoms among college students in Split, Croatia, and positive influence of sport activity on decreasing the depression symptoms. Authors screened all 664 college students of the first year of study. All of them were over the 18 years and the mean age was 19.4 +/- 1.2 years. There were 466 females (70.2%) and 178 (26.8%) males. They answered The Beck Depression Inventory (BDI) and questionnaire about their sport activity (no sport activity, recreational and active in sports). For the purpose of the analysis depressive symptoms were defined as a score of > 11. Chi-square and Mann-Whitney test were used for data analysis. 9.4% of the students had significant depression symptoms (score > 11). No one student had score > 26 (symptoms of major depression). Statistically significant lower score on BDI have students who are active in sports (score median = 3) compared to group of recreational (score median = 4) and in correlation to group who are not active in sports (score median = 5) (Kruskal-Wallis: p < 0.001). In the group of active in sports (N = 254) there are only 5.5% with depressions symptoms, while in the group of non active in sports (N = 60) are 18 depressive (chi2-test: p = 0,005). Females are statistically more depressed than males (chi2-test: p = 0.01). In the female group 49 (10.5%) are depressed, and in the male group are 9 (5%). Compared to gender in separate analysis we did not find correlation of decreasing depression symptoms and sport activity among males (chi2-test: p = 0.47), while in females we find that sport activity has significant effect (chi2-test: p = 0.026). Our results shoved moderate values of depression symptoms among college population in Split, Croatia. More females than males experienced depressive symptoms. While sport activity did not have significant influence on the depression in male population, it has significant influence in reducing the depression symptoms among females.

    Taiwan is developing a long-term space program which is entering its next 15 years of planning cycle. Since its establishment in 1992, the National Space Program Office has played a key role in introducing satellite technology and space experiments into Taiwan. In parallel, basic research in space science and remote-sensing observations are being promoted in different institutions. A combination of these efforts has earned Taiwan a compact but effective space program capable of mounting satellite missions and advanced study in various disciplines of space science. The satellite data receiving and data processing facilities are particularly valuable in addressing issues related to environmental protection, natural hazards and economic planning. At the present time, Taiwan's international cooperative space activities are still very limited in scope but there is a wide ranging of possibilities which could be pursued together with other developing nations in space research under the auspice of COSPAR.

    2015-07-01

    Drawing on public commitment theory, this research examined the association between Facebook self-presentations of coupledom and relationship longevity among college-aged dating partners. Using a longitudinal design and a path model analytic approach, this study shows that Facebook self-presentational cues (i.e., being listed as "in a relationship," posting dyadic photographs, writing on the partner's wall) were associated with an increase in relationship commitment for dating couples, which, in turn, increased their likelihood of remaining together after 6 months. Contrary to predictions, the number of mutual Friends and the number of posts written by partners on participants' walls were negatively related to relationship commitment. This study is the first to apply public commitment theory to an online romantic relationship context, and one of the few to examine the effects of Facebook on the state and fate of romantic relationships.

    Study of communication in cellular systems requires precise activation of targeted cell(s) in the network. In contrast to chemical, electrical, thermal, mechanical stimulation, optical stimulation is non-invasive and is better suited for stimulation of targeted cells. As compared to visible lasers, the near infrared (NIR) microsecond/nanosecond pulsed laser beams are being used as preferred stimulation tool as they provide higher penetration depth in tissues. Femotosecond (FS) laser beams in NIR are also being used for direct and indirect (i.e. via two-photon optogenetics) stimulation of cells. Here, we present a comparative evaluation of efficacy of NIR FS laser beam for direct (no optogenetic sensitization) and 2ph optogenetic stimulation of cells. Further, for the first time, we demonstrate the use of blue (~450 nm, obtained by second harmonic generation) FS laser beam for stimulation of cells with and without Channelrhodopisn-2 (ChR2) expression. Comparative analysis of photocurrent generated by blue FS laser beam and continuous wave blue light for optogenetics stimulation of ChR2 transfected HEK cells will be presented. The use of ultrafast laser micro-beam for focal, non-contact, and repeated stimulation of single cells in a cellular circuitry allowed us to study the communication between different cell types.

    Here we report on clearly identified seasonal changes of gullies observed within the last two martian years (MY) on slopes of a south polar pit, which is located in a filled crater (diameter ~54 km) north of Sisyphi Cavi at ~68.5°S and ~1.5°E. Using new high-resolution imaging (High Resolution Imaging Science Experiment, HiRISE), temperature (Thermal Emission Spectrometer, TES) and spectral data (Compact Reconnaissance Imaging Spectrometer for Mars, CRISM; Observatoire pour la Minéralogie, l'Eau, les Glaces et l'Activité, OMEGA), we analyzed the exact timing of changes of gullies and detect the possible medium (CO2, H2O or dry) and mechanism which initiate present day gully activity. Two locations in the study region with clear modifications of gullies were identified in MY 29 between LS 226° and LS 247° and between LS 209° and LS 247°. In MY 30 changes occur in both locations between LS 218° and LS 249°. Modifications are the formation of a new small apron and new deposits within the channel, both associated with the deposition of dark material. Erosion in gully alcoves or channels was not observed. TES data show temperatures between ~180 and ~240 K within the period of gully modifications. Maximum temperatures in the region rise up to ~285 K between LS ~270° and ~310°. Spectral data show a CO2-cover of the study region until LS 227°. CO2-ice free surface are spectrally observed for the first time at LS 249°. H2O was not spectrally detected in the study region and a mixture of CO2 and H2O as presented in [1] cannot be clearly detected. Unfortunately, there are no spectral data available between LS 227° and 249°. Modifications of gullies imply seasonal volatile activity. The activity can be narrowed down to occur between LS 226° and 247° at mean temperatures between ~180 and ~240 K. This is in the range of temperatures where CO2 sublimates back into the atmosphere. Based on the temperature range, the most likely candidate for the observed new

    Recently prices of photovoltaic (PV) systems have been reduced considerably and may continue to be reduced making them attractive. If these systems provide electricity over the stipulated warranty period, it would be possible attain socket parity within the next few years. Current photovoltaic module qualifications tests help in minimizing infant mortality but do not guarantee useful lifetime over the warranty period. The PV Module Quality Assurance Task Force (PVQAT) is trying to formulate accelerated tests that will be useful towards achieving the ultimate goal of assuring useful lifetime over the warranty period as well as to assure manufacturing quality. Unfortunately, assuring the manufacturing quality may require 24/7 presence. Alternatively, collecting data on the performance of fielded systems would assist in assuring manufacturing quality. Here PV systems installed by home-owners and small businesses can constitute as an important untapped source of data. The volunteer group, PV - Reliable, Safe and Sustainable Quality! (PVRessQ!) is providing valuable service to small PV system owners. Photovoltaic Reliability Group (PVRG) is initiating activities in USA and Brazil to assist home owners and small businesses in monitoring photovoltaic (PV) module performance and enforcing warranty. It will work in collaboration with small PV system owners, consumer protection agencies. Brazil is endowed with excellent solar irradiance making it attractive for installation of PV systems. Participating owners of small PV systems would instruct inverter manufacturers to copy the daily e-mails to PVRG and as necessary, will authorize the PVRG to carry out review of PV systems. The presentation will consist of overall activities of PVRG in USA and Brazil.

    Background The incidence of cancer is increasing throughout the world. One of the prime aims of its management is early diagnosis and therapeutic intervention. Factors causing delay to either of these goals should be identified and rectified. Aim To identify the factors causing delayed initial diagnosis and subsequent management in patients presenting to the Oncology department. Materials and Methods Three hundred proven cancer patients were prospectively evaluated for the pattern of presentation to the outpatient Department of Radiation Oncology of a Government Medical College (MC) in Central India. Results The mean age of presentation was 51.05 years (range 7 months-77 years). The number of male patients was 168 while females were 132. The duration of symptoms ranged from 20 days to 3 years. The number of patients with little/no education presented mainly in advanced stages as compared to their educated counterpart and this difference was statistically significant (p<0.001). The number of patients presenting directly to the department was 108, those diagnosed outside and referred to us was 84 while those diagnosed and received some form of oncologic treatment outside and referred thereafter was 108. The difference in the primary delay between patients presenting directly to the MC versus those diagnosed outside was significant (p=0.0126). The mean duration of starting definitive treatment after presentation to the outpatient was 4.68 days (range 0-22 days) and was very significantly (p< 0.001) less than the secondary delays caused to the other two subsets of patients. Conclusion Factors causing delayed presentation are both patient and system related. It is imperative to educate the common people regarding the early signs and symptoms of cancer. At the same time, the system needs to overhaul its efficiency to avoid secondary delays that adversely affect the treatment outcome. An upgradation of the existing oncology facilities in the public sector can achieve this

    2014-01-01

    Brain activity observed at many spatiotemporal scales exhibits a 1/f-like power spectrum, including neuronal membrane potentials, neural field potentials, noninvasive electroencephalography, magnetoencephalography and functional magnetic resonance imaging signals. A 1/f-like power spectrum is indicative of arrhythmic brain activity that does not contain a predominant temporal scale (hence, “scale-free”). This characteristic of scale-free brain activity distinguishes it from brain oscillations. While scale-free brain activity and brain oscillations coexist, our understanding of the former remains very limited. Recent research has shed light on the spatiotemporal organization, functional significance and potential generative mechanisms of scale-free brain activity, as well as its developmental and clinical relevance. A deeper understanding of this prevalent brain signal should provide new insights and analytical tools for cognitive neuroscience. PMID:24788139

    Sangay (5230 m), the southernmost active volcano of the Andean Northern Volcanic Zone (NVZ), sits ˜130 km above a >32-Ma-old slab, close to a major tear that separates two distinct subducting oceanic crusts. Southwards, Quaternary volcanism is absent along a 1600-km-long segment of the Andes. Three successive edifices of decreasing volume have formed the Sangay volcanic complex during the last 500 ka. Two former cones (Sangay I and II) have been largely destroyed by sector collapses that resulted in large debris avalanches that flowed out upon the Amazon plain. Sangay III, being constructed within the last avalanche amphitheater, has been active at least since 14 ka BP. Only the largest eruptions with unusually high Plinian columns are likely to represent a major hazard for the inhabited areas located 30 to 100 km west of the volcano. However, given the volcano's relief and unbuttressed eastern side, a future collapse must be considered, that would seriously affect an area of present-day colonization in the Amazon plain, ˜30 km east of the summit. Andesites greatly predominate at Sangay, there being few dacites and basalts. In order to explain the unusual characteristics of the Sangay suite—highest content of incompatible elements (except Y and HREE) of any NVZ suite, low Y and HREE values in the andesites and dacites, and high Nb/La of the only basalt found—a preliminary five-step model is proposed: (1) an enriched mantle (in comparison with an MORB source), or maybe a variably enriched mantle, at the site of the Sangay, prior to Quaternary volcanism; (2) metasomatism of this mantle by important volumes of slab-derived fluids enriched in soluble incompatible elements, due to the subduction of major oceanic fracture zones; (3) partial melting of this metasomatized mantle and generation of primitive basaltic melts with Nb/La values typical of the NVZ, which are parental to the entire Sangay suite but apparently never reach the surface and subordinate

    [Purpose] This study examined sex differences in physical activity and social cognitive theory factors in Korean college students. [Subjects and Methods] A cross-sectional survey of 688 college students (285 men and 403 women) in Korea was conducted using a self-reported questionnaire. [Results] There was a significant difference in the level of physical activity between male and female students. The significant predictors of physical activity for male students were physical activity goals, physical activity self-efficacy, and sitting time. Meanwhile, those for female students were perceived weight, physical activity goal, physical activity outcome expectations, and sitting time. [Conclusion] Sex differences should be considered when developing interventions to increase physical activity. PMID:26180293

    The proportion of African-American students in the College of Earth and Mineral Sciences (EMS) at Penn State is 3.3 percent, only slightly lower than the overall University Park campus proportion of 4 percent. Retention rates within EMS are excellent; a recent survey found that EMS ranks highest in student satisfaction overall at the University Park campus. Our goal to increase diversity in EMS disciplines requires us to attract new students to Penn State rather than recruiting from other areas within the institution. We have implemented three programs that appear successful in this regard, and are thus likely to form a viable pipeline from high school through graduate school. These programs operate at a college-wide level and are co-sponsored by AESEDA (Alliance for Earth Science, Engineering and Development in Africa). SEEMS (Summer Experience in EMS) is a partnership with Upward Bound Math and Science, adding 30 hours of directed research to their existing enrichment program. Students identified in 9th grade spend 6 weeks each summer in residence at PSU, where they receive classroom instruction in core academic areas in addition to a group research project led by faculty and graduate students. SEEMS students are likely PSU recruits: all are accepted to college, 85 percent plan to attend college within PA, and all have strong family support for education as well as for careers in EMS. Pre- and post-experience surveys indicate strong positive changes in perception of EMS careers, particularly with regard to levels of intellectual challenge and starting salary. We maintain personal contact with these students and encourage them to attend PSU when they graduate. SROP (Summer Research Opportunity Program) is administered by the Committee on Institutional Cooperation, the academic arm of the Big 10, and provides residential research internships for students from HBCU and MSI campuses. EMS participates in SROP by funding research interns and providing strong individual

    2014-01-01

    Background and aims: The primary objective of the present study was to investigate which cell-phone activities are associated with cell-phone addiction. No research to date has studied the full-range of cell-phone activities, and their relationship to cell-phone addiction, across male and female cell-phone users. Methods: College undergraduates (N = 164) participated in an online survey. Participants completed the questionnaire as part of their class requirements. The questionnaire took 10 and 15 minutes to complete and contained a measure of cell-phone addiction and questions that asked how much time participants spent daily on 24 cell-phone activities. Results: Findings revealed cell-phone activities that are associated significantly with cell-phone addiction (e.g., Instagram, Pinterest), as well as activities that one might logically assume would be associated with this form of addiction but are not (e.g., Internet use and Gaming). Cell-phone activities that drive cell-phone addiction (CPA) were found to vary considerably across male and female cell-phone users. Although a strong social component drove CPA for both males and females, the specific activities associated with CPA differed markedly. Conclusions: CPA amongst the total sample is largely driven by a desire to connect socially. The activities found to be associated with CPA, however, differed across the sexes. As the functionality of cell-phones continues to expand, addiction to this seemingly indispensable piece of technology becomes an increasingly realistic possibility. Future research must identify the activities that push cell-phone use beyond its “;tipping point” where it crosses the line from a helpful tool to one that undermines our personal well-being and that of others.

    Friedman, Carly K; Ayres, Melanie

    2013-01-01

    Engagement in activism is related to several aspects of social development in adolescence and emerging adulthood. Therefore, it is important to examine the correlates of different forms of activism, such as feminist collective action, among all youth. However, previous research has not investigated young sexual-minority women's engagement with feminist collective action. This study examined predictors of college-aged heterosexual and sexual-minority women's commitment to and participation in feminist activism. Sexual orientation, number of years in college, social support, experiences with discrimination, and gender identity were tested as predictors of commitment to and participation in feminist activism with a sample of 280 college-aged women (173 heterosexuals and 107 sexual minorities). Similar predictors were related to both commitment to and participation in feminist activism. However, for sexual-minority women, but not heterosexual women, the number of years in college was correlated with participation in feminist activism. Young sexual-minority women reported more participation in feminist activism than did heterosexual women, even after controlling for social support, discrimination, and gender identity.

    In the murine model of cerebral malaria caused by P. berghei ANKA (PbA), parasite-specific CD8+ T cells directly induce pathology and have long been hypothesized to kill brain endothelial cells that have internalized PbA antigen. We previously reported that brain microvessel fragments from infected mice cross-present PbA epitopes, using reporter cells transduced with epitope-specific T cell receptors. Here, we confirm that endothelial cells are the population responsible for cross-presentation in vivo, not pericytes or microglia. PbA antigen cross-presentation by primary brain endothelial cells in vitro confers susceptibility to killing by CD8+ T cells from infected mice. IFNγ stimulation is required for brain endothelial cross-presentation in vivo and in vitro, which occurs by a proteasome- and TAP-dependent mechanism. Parasite strains that do not induce cerebral malaria were phagocytosed and cross-presented less efficiently than PbA in vitro. The main source of antigen appears to be free merozoites, which were avidly phagocytosed. A human brain endothelial cell line also phagocytosed P. falciparum merozoites. Besides being the first demonstration of cross-presentation by brain endothelial cells, our results suggest that interfering with merozoite phagocytosis or antigen processing may be effective strategies for cerebral malaria intervention.

    The long-range Fermilab program requires fully capitalizing on the world's highest energy accelerator, the Tevatron, throughout the decade of the 90's. The program calls for increasing the collider luminosity with each successive run until peak luminosities of ≳5×1031 cm-2 s-1 and integrated luminosities of ≳100 pb-1 per run are achieved, effectively doubling the mass range accessible for discovery. If the quark lies at the upper range of the mass of the Tevatron, then increasing the energy of the collider operation could prove to be a crucial factor in the future program as well. In order to achieve these goals, we present a highly challenging upgrade of the present accelerator complex, called Fermilab III. In order to increase this performance level by a factor of 50, many changes are needed. Such a plan, of necessity, has modifications in almost all areas of the accelerator as the present system is reasonably optimized. (AIP)

    The prevalence of equine glaucoma seen by the ophthalmology service at the Western College of Veterinary Medicine (WCVM) was 6.5%. The majority of cases (11/13) were associated with clinical manifestations of uveitis. Congenital glaucoma was documented in 1 case, and primary glaucoma was diagnosed in a 12-year-old quarter horse. There were no breed or sex predilections evident. Affected horses were middle-aged to old (average age = 9.5 years, ranging from 2 weeks to 23 years). The clinical manifestations of equine glaucoma included blindness, diffuse corneal edema, corneal vascularization, buphthalmia, corneal striae, recurrent secondary ulcerative keratitis, and less commonly, iris bombé, tapetal hyper-reflectivity, complete pupillary occlusion from posterior synechiae, and optic disc cupping. Elevated intraocular pressure confirmed the diagnosis (n = 10), while 3 cases were normotensive with signs of glaucoma including corneal striae and buphthalmia. Affected eyes were treated medically and/or surgically. Regardless of the therapy instituted, the visual outcome was poor. Most affected eyes were blind at presentation or became blind within a few weeks. Images Figure 1. Figure 2. Figure 3. Figure 4. Figure 5a. PMID:10857031

  20. Present and Future Activities on Neutron Imaging in Argentina

    Tartaglione, Aureliano; Blostein, Jerónimo; Cantargi, Florencia; Marín, Julio; Baruj, Alberto; Meyer, Gabriel; Santisteban, Javier; Sánchez, Fernando

    We present here a short review of the main work which has been done in the latest years in neutron imaging in Argentina, and the future plans for the development of this technique in the country, mainly focused in the design of a new neutron imaging instrument to be installed in the future research reactor RA10. We present here the results of the implementation of the technique in samples belonging to the Argentinean cultural heritage and experiments related with hydrogen storage. At the same time, the Argentinean RA10 project for the design and construction of a 30 MW multipurpose research reactor is rapidly progressing. It started to be designed by the National Atomic Energy Commission (CNEA) and the technology company INVAP SE, both from Argentina, in June 2010. The construction will start in the beginning of 2015 in the Ezeiza Atomic Center, at 36 km from Buenos Aires City, and is expected to be finished by 2020. One of the main aims of the project is to offer to the Argentinean scientific and technology system new capabilities based on neutron techniques. We present here the conceptual design of a neutron imaging facility which will use one of the cold neutron beams, and will be installed in the reactor hall. Preliminary simulation results show that at the farthest detection position, at about 17 m from the cold source, a uniform neutron beam on a detection screen with an intensity of about 108 n/cm2/s is expected.

  1. Interfering with mineralocorticoid receptor activation: the past, present, and future

    PubMed Central

    2014-01-01

    Aldosterone is a potent mineralocorticoid produced by the adrenal gland. Aldosterone binds to and activates the mineralocorticoid receptor (MR) in a plethora of tissues, but the cardiovascular actions of aldosterone are of primary interest clinically. Although MR antagonists were developed as antihypertensive agents, they are now considered to be important therapeutic options for patients with heart failure. Specifically, blocking only the MR has proven to be a difficult task because of its similarity to other steroid receptors, including the androgen and progesterone receptors. This lack of specificity caused the use of the first-generation mineralocorticoid receptor antagonists to be fraught with difficulty because of the side effects produced by drug administration. However, in recent years, several advances have been made that could potentially increase the clinical use of agents that inhibit the actions of aldosterone. These will be discussed here along with some examples of the beneficial effects of these new therapeutic agents. PMID:25165560

    Brookhaven National Laboratory has been involved in advanced neutron sources almost from its inception in 1947. These efforts have mainly focused on steady state reactors beginning with the construction of the first research reactor for neutron beams, the Brookhaven Graphite Research Reactor. This was followed by the High Flux Beam Reactor that has served as the design standard for all the subsequent high flux reactors constructed worldwide. In parallel with the reactor developments BNL has focused on the construction and use of high energy proton accelerators. The first machine to operate over 1 GeV in the world was the Cosmotron. The machine that followed this, the AGS, is still operating and is the highest intensity proton machine in the world and has nucleated an international collaboration investigating liquid metal targets for next generation pulsed spallation sources. Early work using the Cosmotron focused on spallation product studies for both light and heavy elements into the several GeV proton energy region. These original studies are still important today. In this report we discuss the facilities and activities at BNL focused on advanced neutron sources. BNL is involved in the proton source for the Spallation Neutron source, spectrometer development at LANSCE, target studies using the AGS and state-of-the-art neutron detector development.

    Solar forecasting of the level of sun Activity is very important subject for all space programs. Most predictions are based on the physical conditions prevailing at or before the solar cycle minimum preceding the maximum in question. Our aim is to predict the maximum peak of cycle 24 using precursor techniques in particular those using spotless event, geomagnetic aa min. index and solar flux F10.7. Also prediction of exact date of the maximum (Tr) is taken in consideration. A study of variation over previous spotless event for cycles 7-23 and that for even cycles (8-22) are carried out for the prediction. Linear correlation between RM and spotless event around the preceding minimum gives RM24t = 101.9with rise time Tr = 4.5 Y. For the even cycles RM24e = 108.3 with rise time Tr = 3.9 Y. Based on the average aa min. index for the year of sunspot minimum cycles (13 - 23), we estimate the expected amplitude for cycle 24 to be RMaa = 116.5 for both the total and even cycles. Application of the data of solar flux F10.7 which cover only cycles (19-23) was taken in consideration and gives predicted maximum amplitude R24 10.7 = 146, which are over estimation. Our result indicating a somewhat weaker cycle 24 as compared to cycles 21-23.

    In this report, we show evidence for ripple and dune migration in Herschel Crater on Mars. We estimate an average dune migration of 0.8 m and a minimum ripple migration of 1.1 m in a time span of 3.7 Earth-years. These dunes and ripples are mainly shaped by prevailing winds coming from the north, however we also report the presence of secondary winds which elongate the barchans' horns. Such a complex wind scenario is likely caused by the influence of winds blowing off the western crater rim as suggested by the Mars Regional Atmospheric Modeling System (MRAMS), an atmospheric mesoscale model. A multi-directional wind regime at the local scale is also supported by the observed bimodal distribution of the ripple trends. For the first time, a survey integrating the assessment of dune and ripple migration is presented, showing how dune topography can influence the migration patterns of ripples and how underlying topography appears to control the rates of dune migration.

    Background Subsequent publication rate of abstracts presented at meetings is seen as an indicator of the interest and quality of the meeting. We have analyzed characteristics and rate publication in peer-reviewed journals derived from oral communications and posters presented at the 1999 College on Problems of Drug Dependence (CPDD) meeting. Methods All 689 abstracts presented at the 1999 CPDD meeting were reviewed. In order to find the existence of publications derived from abstracts presented at that meeting, a set of bibliographical searches in the database Medline was developed in July 2006. Information was gathered concerning the abstracts, articles and journals in which they were published. Results 254 out of 689 abstracts (36.9%) gave rise to at least one publication. The oral communications had a greater likelihood of being published than did the posters (OR = 2.53, 95% CI 1.80-3.55). The average time lapse to publication of an article was 672.97 days. The number of authors per work in the subsequent publications was 4.55. The articles were published in a total of 84 journals, of which eight were indexed with the subject term Substance-Related Disorders. Psychopharmacology (37 articles, 14.5%) was the journal that published the greatest number of articles subsequent to the abstracts presented at the 1999 CPDD meeting. Conclusion One out of every three abstracts presented to the 1999 CPDD meeting were later published in peer-reviewed journals indexed in Medline. The subsequent publication of the abstracts presented in the CPDD meetings should be actively encouraged, as this maximizes the dissemination of the scientific research and therefore the investment.

    2006-08-01

    College student alcohol abuse remains a significant public health problem, and there is a need for theory-driven and empirically based models to guide prevention efforts. Behavioral theories of choice assume that the decision to consume alcohol is influenced by the relative value of alcohol versus other available activities. In the present study, a sample of college student drinkers (N=108; 56% female, 44% male) who had previously completed a mandatory alcohol intervention completed a measure of alcohol-related and alcohol-free activity participation and enjoyment. The goals of the study were to examine the influence of drinking quantity and contextual variables on activity enjoyment and to identify enjoyable alcohol-free activities that take place on evenings when students might otherwise be drinking. Overall, students found alcohol-related activities more enjoyable than alcohol-free activities, and drinking quantity was positively related to enjoyment. However, alcohol-free activities such as watching movies, going to the theater or museums, going to bars or parties, hanging out with friends, eating at restaurants, and engaging in creative activity were generally as enjoyable as drinking. Alcohol-free activities that included peers or dates were more enjoyable than solitary activities. Men were less likely to engage in alcohol-free activities that included peers and reported less enjoyment related to alcohol-free activities than did women. Further research is required to identify procedures for increasing participation in alcohol-free activities and to determine whether increased alcohol-free activity participation results in decreased alcohol consumption.

    Homeroom (HR) activities have an important role in engineering education at technical colleges. Yatsushiro National College of Technology has made a master plan for them and has been putting the plan into practical use since 2002. This plan is comprehensive and has two main categories, social education and career guidance, both being composed of three sub-categories (e.g., self-understanding and making future plans) . Based on the master plan, each HR teacher makes his own plan for HR activities for his classroom at the beginning of the academic year. We have reached a consensus to share our practice and to improve HR activities for years to come. We also recognize that to carry out HR activities based on a master plan that reflects the school's educational goals is essential in order to train students who are well-prepared, both as engineers and as humans.

    1985-01-01

    The effect of maximal treadmill exercise on plasma concentrations of vasopressin (AVP); renin activity (PRA); and aldosterone (ALDO) was studied in nine female college basketball players before and after a 5-month basketball season. Pre-season plasma AVP increased (p less than 0.05) from a pre-exercise concentration of 3.8 +/- 0.5 to 15.8 +/- 4.8 pg X ml-1 following exercise. Post-season, the pre-exercise plasma AVP level averaged 1.5 +/- 0.5 pg X ml-1 and increased to 16.7 +/- 5.9 pg X ml-1 after the exercise test. PRA increased (p less than 0.05) from a pre-exercise value of 1.6 +/- 0.6 to 6.8 +/- 1.7 ngAI X ml-1 X hr-1 5 min after the end of exercise during the pre-season test. In the post-season, the pre-exercise PRA was comparable (2.4 +/- 0.6 ngAI X ml- X hr-1), as was the elevation found after maximal exercise (8.3 +/- 1.9 ngAI X ml- X hr-1). Pre-season plasma ALDO increased (p less than 0.05) from 102.9 +/- 30.8 pg X ml-1 in the pre-exercise period to 453.8 +/- 54.8 pg X ml-1 after the exercise test. In the post-season the values were 108.9 +/- 19.4 and 365.9 +/- 64.4 pg X ml-1, respectively. Thus, maximal exercise in females produced significant increases in plasma AVP, renin activity, and ALDO that are comparable to those reported previously for male subjects. Moreover, this response is remarkably reproducible as demonstrated by the results of the two tests performed 5 months apart.

    Using data from a nationally representative sample of college women, the current study examines attention deficit hyperactivity disorder (ADHD) as a potential risk factor in the prediction of sexual victimization among college women and as an extension of the lifestyles/routine activities framework. The findings indicate that college women with ADHD experienced sexual victimization at significantly higher rates than college women without ADHD. Furthermore, ADHD emerged as a significant predictor of sexual victimization across models. The lifestyles/routine activities theory also received general support, particularly for the concepts of exposure, proximity, and guardianship. This research suggests that other risk factors outside the lifestyles/routine activities framework are important in the prediction of sexual victimization in college women.

    Shekoyan, V.; Scal, R.

    2014-12-01

    A new active learning introductory gemology studio course with a lab component has been created at Queensborough Community College with the support of NSF TUES grant. Various pedagogical techniques that have shown efficacy at 4-year colleges have been implemented and adopted to improve student learning and course retention as well as to stimulate their interest in science and in STEM careers. The course covered broad range of STEM topics central to the gemology curriculum, including concepts from geology, mineralogy, physics and chemistry. Lectures and labs were linked. Students' misconceptions were addressed via guided laboratory activities in a studio-learning environment. The course used peer-based learning and problem solving by creating student groups that discussed observations and measurements. Discussion groups were required to observe, synthesize, and evaluate data for presentations. The goal was to empower student learning and peer-based teaching and to recruit early career, often non-STEM students, to earth science. Students were often prompted to engage in self-reflections on their learning. In this presentation we will present the analysis of the evaluation of the course and its impact on community college students. Some of the evaluation tools we have used are pre- and post- knowledge surveys, science attitude and belief surveys as well as a Geological Interest instrument. Parallel sections of traditionally taught lecture-only courses (taught by the same instructor) were utilized as a control group in the analysis. The pedagogical implications of the analysis on instruction and course design will be discussed as well.

    2013-01-01

    Major histocompatibility complex class I (MHC I) on antigen presenting cells (APCs) is a potent molecule to activate CD8+ T cells and initiate immunity. P2X7 receptors (P2X7Rs) are present on the plasma membrane of APCs to sense the extracellular danger signal adenosine-5′-triphosphate (ATP). P2X7R activates the inflammasome and the release of IL-1β in macrophages and other immune cells to initiate the inflammatory response. Here we show that P2X7R stimulation by ATP in APCs decreased the amount of MHC I at the plasma membrane. Specific antagonism or genetic ablation of P2X7R inhibited the effects of ATP on levels of cellular MHC I. Furthermore, P2X7R stimulation was able to inhibit activation of CD8+ T cells via specific MHC I-oligopeptide complexes. Our study suggests that P2X7R activation on APCs is a novel inhibitor of adaptive CD8+ T cell immunity. PMID:23940597

    Few studies analyze determinants and patterns of physical activity among college students, so it has not been possible to carry out effective interventions to promote this practice. The aim of this study was to analyze the associations between some personal, social, and environmental determinants, practice of physical activity and future intention to practice in a sample of 639 university students (321 men and 318 women), mean age 21.43 years (+/- 2.78). Physical fitness self-perception, physical activity history, and coach's support to practice physical activity have a direct effect on the practice of physical activity and an indirect effect on future intention to practice, both in men and women. The practice of physical activity has also a direct effect on future intention to practice. Likewise, the participation in sport competitions predicts practice of physical activity and future intention in men, whereas being a member of a sports club predicts practice and future intention in women.

    Both heavy drinking and related risky sexual behavior among college students are common and are often associated with a number of negative consequences. A previously reported randomized controlled trial showed that a brief personalized normative feedback (PNF) intervention reduced the alcohol consumption and alcohol-related risky sexual behavior of heavy drinking, sexually active college students (Lewis et al., 2014). For the present study, we examined what activities students were engaged in when viewing the feedback, as well as who they were with and where they were when receiving the intervention. Furthermore, we conducted supplemental analyses with perceived attentiveness as a hypothesized predictor of change using the same sample (N = 480). Findings indicated that most students were engaged in activities when viewing the feedback and that most students viewed the feedback alone and at home. Furthermore, results revealed PNF to be most effective in reducing drinks per week among participants who reported greater attention. Clinical implications and suggestions for additional research examining how attentiveness can be increased during Web-based interventions are discussed.

    2012-01-01

    Background This quasi-experimental study investigated a game intervention—specifically, an alternate reality game (ARG)—as a means to influence college students’ physical activity (PA). An ARG is an interactive narrative that takes place in the real world and uses multiple media to reveal a story. Method Three sections of a college health course (n = 115 freshman students) were assigned either to a game group that played the ARG or to a comparison group that learned how to use exercise equipment in weekly laboratory sessions. Pre- and post-intervention measures included weight, waist circumference, body mass index (BMI), percentage body fat (PBF), and self-reported moderate physical activity (MPA) and vigorous physical activity (VPA), and PA (steps/week). Results A significant group x time interaction (p = .001) was detected for PA, with a significant increase in PA for the game (p < .001) versus a significant decrease (p = .001) for the comparison group. Significant within-group increases for weight (p = .001), BMI (p = .001), and PBF (p = .001) were detected. A significant group x time interaction (p = .001) was detected when analyzing self-reported VPA, with both groups reporting decreases in VPA over time; however, the decrease was only significant for the comparison group (p < .001). No significant group differences were found for MPA. Conclusions It is important that any intervention meet the needs and interests of its target population. Here, the ARG was designed in light of the learning preferences of today’s college students—collaborative and social, experiential and media-rich. Our results provide preliminary evidence that a game intervention can positively influence PA within the college student population. PMID:22920809

    Physical inactivity poses concern for health risks among all groups in the United States. Active transportation (AT) (e.g., bicycling) is one way of being physically active and may be helpful in promoting physical activity. This study characterized active transportation behavior among college students using the Theory of Planned Behavior. This study sought to describe predictors, including Theory of Planned Behavior (TPB) constructs, of AT behavior among college students at a large Midwest university. Students were recruited through the university registrar's office and e-mailed an electronic survey. Differences among AT users were determined using t-tests, and predictors of AT were identified using regression analysis. Significant differences between AT users for all TPB constructs were observed. Regression analysis using only TPB constructs accounted for 11.58% explained variation in AT use. Other variables added to the model resulted in 44.44% explained variation in AT use. The final model included subjective norms, age, perceived behavioral control, and transportation type and destination. The results of this research are insightful in explaining AT behavior. Perceived norms and the level of control students had regarding their method of transportation were important contributions to AT use. These results may be applied to promoting physical activity in community health.

    This article considers queer-driven student activism at Smith College, as well as admissions policy shifts at a number of prominent U.S. women's colleges for transgender women's inclusion. The author illustrates how student attempts to dismantle the transmisogyny at Smith as a purportedly feminist "women's" space, as well as some women's colleges' shifts in admissions policy, challenge divisions between transgender and cisgender women. This paradigmatic shift reflects the campuses as comparative havens for gender and sexual exploration, the influence of postmodern gender theory in understanding identity, and the growth of "queer" as an all-encompassing signifier for sexual and gender transgression.

  11. Effects of using presentation formats that accommodate the learner's multiple intelligences on the learning of freshman college chemistry concepts

    NASA Astrophysics Data System (ADS)

    Brown Wright, Gloria Aileen

    Howard Gardner's Theory of Multiple Intelligences identifies linguistic, spatial and logical-mathematical intelligences as necessary for learning in the physical sciences. He has identified nine intelligences which all persons possess to varying degrees, and says that learning is most effective when learners receive information in formats that correspond to their intelligence strengths. This research investigated the importance of the multiple intelligences of students in first-year college chemistry to the learning of chemistry concepts. At three pre-selected intervals during the first-semester course each participant received a tutorial on a chemistry topic, each time in a format corresponding to a different one of the three intelligences, just before the concept was introduced by the class lecturer. At the end of the experiment all subjects had experienced each of the three topics once and each format once, after which they were administered a validated instrument to measure their relative strengths in these three intelligences. The difference between a pre- and post-tutorial quiz administered on each occasion was used as a measure of learning. Most subjects were found to have similar strengths in the three intelligences and to benefit from the tutorials regardless of format. Where a difference in the extent of benefit occurred the difference was related to the chemistry concept. Data which indicate that students' preferences support these findings are also included and recommendations for extending this research to other intelligences are made.

    College students tend to lack access to health information. Because social networking sites (SNSs) are popularly adopted by college students, SNSs are considered to be good media channels for college students to obtain health-related information. This study examines the factors that influence college students' health information-seeking and -sharing activities on Facebook. An online survey was distributed to college students between the ages of 18 and 29 to determine intentions pertaining to health information activities according to the factors identified for the study. The factors included both contextual factors (such as health topic sensitivity and health information sources) as well as user factors (such as demographics). Our findings showed that college students are willing to read and post health-related information on Facebook when the health topic is not sensitive. In addition, there are clear differences in preferences between professional sources and personal sources as health information sources. It was found that most user factors, except gender, have no influence on health information activities. The impacts of SNS contexts, awareness of information sources, types of interlocutors, and privacy concerns are further discussed.

    Few studies examine the mechanisms that link body image to sexual satisfaction in women. Using the tenets of objectification theory, this study investigated the relationships between body surveillance, body shame, body self-consciousness during sexual activities, and sexual satisfaction in an ethnically diverse sample of American female college students (N=368), while controlling for relationship status and body mass index. Results based on self-report measures of these constructs suggested that body shame and body self-consciousness during sexual activity were negatively correlated with sexual satisfaction. Additionally, path analysis indicated that body surveillance predicted increased body self-consciousness during sexual activity, partially mediated by body shame. Body self-consciousness, in turn, predicted decreased sexual satisfaction. Overall, study findings highlight the negative consequences of body image concerns for women's sexual satisfaction.

A random sample of 787 students (48% males and 52% females) was chosen and weight and height were measured to obtain body mass index (BMI, kg/m2). Associated social and health factors were obtained using a questionnaire. Those reporting being physically inactive numbered 354 and the remaining 433 were active. Obesity among males was 13% and was 10.5% among females. The social and health factors that were found to be significantly associated with physical activity among the students were gender (P < .001), marital status (P < .05), BMI category (obese or nonobese) (P < .05), last dental and health checkup (P < .01), desiring a higher degree (P < .001), and countries preferred for visiting (P < .01). Males significantly exceeded females in the practice of physical activity. In conclusion, behavioural modifications, intervention studies, and health education touting the benefits of being physically active should be instituted to increase the practice of sports and other physical activities in order to control and decrease obesity-related morbidity and mortality.

    Objective We compared fruit and vegetable (FV) intake, physical activity (PA), and overweight/ obesity among Black and White females attending two- and four-year colleges. Methods We recruited 24,055 students at six colleges in the Southeast to complete an online survey, yielding 4840 responses (20.1% response rate). The current analyses focused on the 2276 Black and White females. Results Binary logistic regression analyses indicated that recommended FV intake among White females was associated with greater extraversion (Odds Ratio [OR] = 1.05, 95% Confidence Interval [CI] 1.00, 1.11, p = 0.05) and greater conscientiousness (OR = 1.08, CI 1.02, 1.14, p = 0.01), whereas among Black females correlates included greater openness to experience (OR = 1.08, CI 1.01, 1.15, p = 0.03). Ordinal logistic regression analyses indicated that, among White females, greater PA was associated with attending a four-year college (Beta = 0.27, CI 0.01, 0.53, p = 0.04), whereas among Black females, correlates were with younger age (Beta = 0.01, CI 0.17, 0.03, p = 0.003) and greater emotional stability (Beta = 0.07, CI 0.01, 0.13, p = 0.02). Binary logistic regression analyses indicated that, among White females, being overweight or obese was associated with older age (OR = 1.08, CI 1.01, 1.16, p = 0.03), attending a two-year college (OR = 1.62, CI 1.22, 2.16, p = 0.001), and lower satisfaction with life (OR = 0.96, CI 0.94, 0.98, p = 0.002), whereas among Black females, being overweight or obese was associated with older age (OR = 1.87, CI 1.10, 1.28, p < 0.001). Conclusions Identifying factors related to obesity-related factors is critical in developing interventions targeting factors associated with overweight and obesity among Black and White females attending two- and four-year colleges. Moreover, understanding different college settings and the contextual factors associated with overweight/obesity is critical. PMID:25328836

    It is well-known that musicians are at risk for music-induced hearing loss, however, systematic evaluation of music exposure and its effects on the auditory system are still difficult to assess. The purpose of the study was to determine if college students in jazz band-based instructional activity are exposed to loud classroom noise and consequently exhibit acute but significant changes in basic auditory measures compared to non-music students in regular classroom sessions. For this we (1) measured and compared personal exposure levels of college students (n = 14) participating in a routine 50 min jazz ensemble-based instructional activity (experimental) to personal exposure levels of non-music students (n = 11) participating in a 50-min regular classroom activity (control), and (2) measured and compared pre- to post-auditory changes associated with these two types of classroom exposures. Results showed that the L eq (equivalent continuous noise level) generated during the 50 min jazz ensemble-based instructional activity ranged from 95 dBA to 105.8 dBA with a mean of 99.5 ± 2.5 dBA. In the regular classroom, the L eq ranged from 46.4 dBA to 67.4 dBA with a mean of 49.9 ± 10.6 dBA. Additionally, significant differences were observed in pre to post-auditory measures between the two groups. The experimental group showed a significant temporary threshold shift bilaterally at 4000 Hz (P < 0.05), and a significant decrease in the amplitude of transient-evoked otoacoustic emission response in both ears (P < 0.05) after exposure to the jazz ensemble-based instructional activity. No significant changes were found in the control group between pre- and post-exposure measures. This study quantified the noise exposure in jazz band-based practice sessions and its effects on basic auditory measures. Temporary, yet significant, auditory changes seen in music students place them at risk for hearing loss compared to their non-music cohorts.

  17. Publication rates of manuscript presentations at the American College of Foot and Ankle Surgeons Annual Scientific Conference between 1999 and 2008.

    Publication is the ultimate desired end point of scientific research. However, oral manuscript presentations of research studies are often referenced in textbooks, journal articles, and industry white papers, and, as a result, influence treatment care plans. No data exist for the actual publication rate of podiatric foot and ankle surgery oral manuscript presentations. Therefore, the objective of this study was to determine the actual publication rates of oral manuscript presentations at the American College of Foot and Ankle Surgeons (ACFAS) Annual Scientific Conference over 10 years. Print or electronic media for the ACFAS Annual Scientific Conference official program between 1999 and 2008 were obtained. Each year's official program was hand searched for any oral manuscript presentation, and, when identified, the title and authors were individually searched through electronic internet-based search engines to determine whether an oral manuscript presentation had been followed by publication of a full-text article. Additionally, pertinent journals were hand searched for potential articles. A total of 67.5% (139/206) oral manuscript presentations were ultimately published in 1 of 12 medical journals in a mean of 14.5 months. All journals except one (91.7%) represented peer-reviewed journals. The publication rate of oral manuscript presentations at the ACFAS Annual Scientific Conference is similar to or greater than orthopaedic subspecialties, including foot and ankle surgery, publication rates. Based on the above, attendees of the ACFAS Annual Scientific Conference should be aware that the majority of oral manuscript material presented at the ACFAS Annual Scientific Conference can be considered as accurate because they survive the rigors of the peer-review process more than two thirds of the time.

    Objective. To investigate the efficacy of using “Instagram application” with a “home-exercise program” as a motivational stimulus in improving physical activity (PA) adherence levels among female college students. Methods. Fifty-eight female undergraduate students with the mean age 20.3 ± 0.96 years participated. Participants were divided into two groups: intervention and the control group; both the groups received an exercise program and the intervention group was additionally motivated by “Instagram.” Adherence to PA was measured by using an adherence sheet. The Exercise Motivation Inventory (EMI-2) was used to assess the motivational factors. Results. The most frequent motivational factors were extrinsic as assessed using the EMI-2. “Positive health” was the most frequent factor mentioned of the two types with 47% of the sample. The intervention group adhered with 17% more to the activity program compared to the control group. Moreover, 72% of the participants in the intervention and control groups found the activity program flexible enough to be performed at home; they agreed about its effectiveness on adherence (53%). Conclusions. The use of Instagram with the home exercise program as a motivational modality could be attractive and effective to reinforce adherence and maintain an appropriate PA level.

    2014-01-01

    How adolescents spend their time has long-term implications for their educational, health, and labor market outcomes, yet surprisingly little research has explored the time use of students across days and semesters. The current study used longitudinal daily diary data from a sample of college students attending a large public university in the Northeastern US (n = 726, Mage = 18.4) that was followed for 14 days within each of 7 semesters (for up to 98 diary days per student). The study had two primary aims. The first aim was to explore demographic correlates of employment time, organized activity time, and academic time. The second aim was to provide a rigorous test of the time trade-off hypothesis, which suggests that students will spend less time on academics when they spend more time on employment and extracurricular activities. The results demonstrated that time use varied by gender, parental education, and race/ethnicity. Furthermore, the results from multi-level models provided some support for the time trade-off hypothesis, although associations varied by the activity type and whether the day was a weekend. More time spent on employment was linked to less time spent on academics across days and semesters whereas organized activities were associated with less time on academics at the daily level only. The negative associations between employment and academics were most pronounced on weekdays. These results suggest that students may balance certain activities across days, whereas other activities may be in competition over longer time frames (i.e., semesters). PMID:25381597

    2012-09-18

    Catalytic atom maps (CAMs) are minimal models of enzyme active sites. The structures in the Protein Data Bank (PDB) were examined to determine if proteins with CAM-like geometries in their active sites all share the same catalytic function. We combined the CAM-based search protocol with a filter based on the weighted contact number (WCN) of the catalytic residues, a measure of the "crowdedness" of the microenvironment around a protein residue. Using this technique, a CAM based on the Ser-His-Asp catalytic triad of trypsin was able to correctly identify catalytic triads in other enzymes within 0.5 Å rmsd of the CAM with 96% accuracy. A CAM based on the Cys-Arg-(Asp/Glu) active site residues from the tyrosine phosphatase active site achieved 89% accuracy in identifying this type of catalytic functionality. Both of these CAMs were able to identify active sites across different fold types. Finally, the PDB was searched to locate proteins with catalytic functionality similar to that present in the active site of orotidine 5'-monophosphate decarboxylase (ODCase), whose mechanism is not known with certainty. A CAM, based on the conserved Lys-Asp-Lys-Asp tetrad in the ODCase active site, was used to search the PDB for enzymes with similar active sites. The ODCase active site has a geometry similar to that of Schiff base-forming Class I aldolases, with lowest aldolase rmsd to the ODCase CAM at 0.48 Å. The similarity between this CAM and the aldolase active site suggests that ODCase has the correct catalytic functionality present in its active site for the generation of a nucleophilic lysine.

    The transition from adolescence to adulthood is an important period for establishing behavioral patterns that affect long-term health and chronic disease risk. Nelson and colleagues speculated that developmental changes and changes in living situation may play an important role in the nutrition and physical activity behaviors of college students. Data from the University Life Study, a longitudinal study of college students that includes web-based surveys administered 14 consecutive days each semester, were used to examine fruit, vegetable, and sugared soda consumption, physical activity, and sedentary activity behaviors across seven semesters. Estimates for each semester were calculated to determine the frequency with which students consumed fruits, vegetables, and sugared soda, engaged in moderate to vigorous physical activity, and engaged in sedentary activities. Four models, estimated with HLM 6.04, were used to predict changes in these behaviors across the seven semesters. Living on or off campus was included to determine if this explained additional variance. Results indicated that few college students consumed fruits and vegetables or exercised at optimal levels during the seven semesters surveyed. Daily fruit and vegetable consumption and daily physical activity declined significantly from the first to the seventh semester. For both of these findings, living off campus exacerbated the problem. Average number of hours of sedentary behaviors declined over time, as did number of days on which at least one sugared soda was consumed. Living location did not explain additional variance in these positive trends. Implications for policy, practice, and future research are discussed. PMID:23232092

    Social-cognitive theories, such as the theory of planned behavior, posit intentions as proximal influences on physical activity (PA). This paper extends those theories by examining within-person variation in intentions and moderate-to-vigorous physical activity (MVPA) as a function of the unfolding constraints in people's daily lives (e.g., perceived time availability, fatigue, soreness, weather, overeating). College students (N = 63) completed a 14-day diary study over the Internet that rated daily motivation, contextual constraints, and MVPA. Key findings from multilevel analyses were that (1) between-person differences represented 46% and 33% of the variability in daily MVPA intentions and behavior, respectively; (2) attitudes, injunctive norms, self-efficacy, perceptions of limited time availability, and weekend status predicted daily changes in intention strength; and (3) daily changes in intentions, perceptions of limited time availability, and weekend status predicted day-to-day changes in MVPA. Embedding future motivation and PA research in the context of people's daily lives will advance understanding of individual PA change processes. PMID:24197717

    1. Homogenates of whole tissues were shown to contain both intracellular and extracellular factors that affected particulate adenylate cyclase activity in vitro. Factors present in the extracellular fluids produced an inhibition of basal, hormone- and fluoride-stimulated enzyme activity but factors present in the cell cytosol increased hormone-stimulated activity with relatively little effect on basal or fluoride-stimulated enzyme activity. 2. The existence of this cytosol factor or factors was investigated using freshly isolated human platelets, freshly isolated rat hepatocytes, and cultured cells derived from rat osteogenic sarcoma, rat calvaria, mouse melanoma, pig aortic endothelium, human articular cartilage chondrocytes and human bronchial carcinoma (BEN) cells. 3. The stimulation of the hormone response by the cytosol factor ranged from 60 to 890% depending on the tissue of origin of the adenylate cyclase. 4. In each case the behaviour of the factor was similar to the action of GTP on that particular adenylate cyclase preparation. 5. No evidence of tissue or species specificity was found, as cytosols stimulated adenylate cyclase from their own and unrelated tissues to the same degree. 6. In the human platelet, the inclusion of the cytosol in the assay of adenylate cyclase increased the rate of enzyme activity in response to stimulation by prostaglandin E1 without affecting the amount of prostaglandin E1 required for half-maximal stimulation or the characteristics of enzyme activation by prostaglandin E.

    Here we show that the multifunctionality of Janus particles can be exploited for in vitro T cell activation. We engineer bifunctional Janus particles on which the spatial distribution of two ligands, anti-CD3 and fibronectin, mimics the "bull's eye" protein pattern formed in the membrane junction between a T cell and an antigen-presenting cell. Different levels of T cell activation can be achieved by simply switching the spatial distribution of the two ligands on the surfaces of the "bull's eye" particles. We find that the ligand pattern also affects clustering of intracellular proteins. This study demonstrates that anisotropic particles, such as Janus particles, can be developed as artificial antigen-presenting cells for modulating T cell activation. PMID:25343426

    2015-02-01

    It is unknown to what extent briefly presented emotional words can be processed without awareness. By means of two independent functional magnetic resonance imaging studies, using either a block or an event-related design, we investigated brain activation to very briefly presented threat related and neutral words during two backward masking conditions (with and without gap between target and mask). In both experiments, emotional words were perceived during the supraliminal "with gap" condition, but they were not recognized during the subliminal "without gap" condition, as indicated by signal detection theory analysis. Imaging results of both experiments showed increased activation of the amygdala, the medial prefrontal cortex and language-processing cortical areas to negative versus neutral words during supraliminal but not subliminal conditions. These results suggest that even very briefly presented emotional words are capable of triggering increased cortical and subcortical processing; however, only when awareness of these stimuli is given.

    2016-01-01

    Background Wearable activity trackers are promising as interventions that offer guidance and support for increasing physical activity and health-focused tracking. Most adults do not meet their recommended daily activity guidelines, and wearable fitness trackers are increasingly cited as having great potential to improve the physical activity levels of adults. Objective The objective of this study was to use the Coventry, Aberdeen, and London-Refined (CALO-RE) taxonomy to examine if the design of wearable activity trackers incorporates behavior change techniques (BCTs). A secondary objective was to critically analyze whether the BCTs present relate to known drivers of behavior change, such as self-efficacy, with the intention of extending applicability to older adults in addition to the overall population. Methods Wearing each device for a period of 1 week, two independent raters used CALO-RE taxonomy to code the BCTs of the seven wearable activity trackers available in Canada as of March 2014. These included Fitbit Flex, Misfit Shine, Withings Pulse, Jawbone UP24, Spark Activity Tracker by SparkPeople, Nike+ FuelBand SE, and Polar Loop. We calculated interrater reliability using Cohen's kappa. Results The average number of BCTs identified was 16.3/40. Withings Pulse had the highest number of BCTs and Misfit Shine had the lowest. Most techniques centered around self-monitoring and self-regulation, all of which have been associated with improved physical activity in older adults. Techniques related to planning and providing instructions were scarce. Conclusions Overall, wearable activity trackers contain several BCTs that have been shown to increase physical activity in older adults. Although more research and development must be done to fully understand the potential of wearables as health interventions, the current wearable trackers offer significant potential with regard to BCTs relevant to uptake by all populations, including older adults.

    2014-01-01

    Using data collected from the Woman's College (WC) Alumni Study, the purpose of this study was to determine whether perceived health status is related to physical activity in older women. A multiple linear regression analysis was conducted to examine the relationship between amounts of physical activity and self-reported health status. The results of the current study reveal that the level of physical activity is significantly correlated with perceived health status. The findings of this study have implications for the assessment of older individuals' health and may lead to interventions that are tailored to increase physical activity among older women.

    With the aim of advancing the literature on impression management in physical activity settings, we developed a theoretically derived 2 by 2 instrument that was designed to measure different types of context-specific self-presentation motives. Following item generation and expert review (Study 1), the instrument was completed by 206 group exercise class attendees (Study 2) and 463 high school physical education students (Study 3). Our analyses supported the intended factor structure (i.e., reflecting acquisitive-agentic, acquisitive-communal, protective-agentic, and protective-communal motives). We found some support for construct validity, and the self-presentation motives were associated with variables of theoretical and applied interest (e.g., impression motivation and construction, social anxiety, social and achievement goals, efficacy beliefs, engagement). Taken together, the results indicate that the Self-presentation Motives for Physical Activity Questionnaire (SMPAQ) may be useful for measuring various types of self-presentation motives in physical activity settings.

    Cardiovascular disease (CVD) is the leading cause of death worldwide. Its prevention emphasizes three aspects: not smoking, physical activity and a healthy diet. Recently, we screened the antithrombotic activity of a selected group of fruits and vegetables. Among them, tomato showed an important effect. The aim of this study was to evaluate and characterize the platelet antiaggregatory activity of tomato (Solanum lycopersicum L.). For this, we obtained aqueous and methanolic tomato extracts and evaluated the effect of pH (2 and 10) and temperature (22, 60 and 100°C) on this activity. Furthermore, in order to isolate the antiaggregant principle, we separated tomato extracts into several fractions (A-D) by size exclusion chromatography. In addition, we evaluated the platelet antiaggregating activity ex vivo in Wistar rats. Aqueous and methanolic extracts of tomato treated at 22, 60 and 100°C and pH 2 and 10 still inhibited platelet aggregation (in vitro). Moreover, it was noted that one of the fractions (fraction C), from both aqueous and methanolic extracts, presented the highest activity (∼70% inhibition of platelet aggregation) and concentration dependently inhibited platelet aggregation significantly compared with control (P < 0.05). These fractions did not contain lycopene but presented two peaks of absorption, at 210 and 261 nm, compatible with the presence of nucleosides. In rats treated with tomato macerates, a mild platelet antiaggregating effect ex vivo was observed. Further studies are required to identify the molecules with platelet antiaggregating activity and antiplatelet mechanisms of action. PMID:22185934

    2015-01-01

    Introduction: To better understand the documented link between mindfulness and longevity, we examine the association between mindfulness and conscious avoidance of secondhand smoke (SHS), as well as the association between mindfulness and physical activity. Method: In Shanghai University of Finance and Economics (SUFE) we surveyed a convenience sample of 1516 college freshmen. We measured mindfulness, weekly physical activity, and conscious avoidance of secondhand smoke, along with demographic and behavioral covariates. We used a multilevel logistic regression to test the association between mindfulness and conscious avoidance of secondhand smoke, and used a Tobit regression model to test the association between mindfulness and metabolic equivalent hours per week. In both models the home province of the student respondent was used as the cluster variable, and demographic and behavioral covariates, such as age, gender, smoking history, household registration status (urban vs. rural), the perceived smog frequency in their home towns, and the asthma diagnosis. Results: The logistic regression of consciously avoiding SHS shows that a higher level of mindfulness was associated with an increase in the odds ratio of conscious SHS avoidance (logged odds: 0.22, standard error: 0.07, p < 0.01). The Tobit regression shows that a higher level of mindfulness was associated with more metabolic equivalent hours per week (Tobit coefficient: 4.09, standard error: 1.13, p < 0.001). Discussion: This study is an innovative attempt to study the behavioral issue of secondhand smoke from the perspective of the potential victim, rather than the active smoker. The observed associational patterns here are consistent with previous findings that mindfulness is associated with healthier behaviors in obesity prevention and substance use. Research designs with interventions are needed to test the causal link between mindfulness and these healthy behaviors. PMID:26308029

    Cathepsin S (CTSS) is a eukaryotic protease mostly expressed in professional antigen presenting cells (APCs). Since CTSS activity regulation plays a role in the pathogenesis of various autoimmune diseases like multiple sclerosis, atherosclerosis, Sjögren's syndrome and psoriasis as well as in cancer progression, there is an ongoing interest in the reliable detection of cathepsin S activity. Various applications have been invented for specific detection of this enzyme. However, most of them have only been shown to be suitable for human samples, do not deliver quantitative results or the experimental procedure requires technical equipment that is not commonly available in a standard laboratory. We have tested a fluorogen substrate, Mca-GRWPPMGLPWE-Lys(Dnp)-DArg-NH2, that has been described to specifically detect CTSS activities in human APCs for its potential use for mouse samples. We have modified the protocol and thereby offer a cheap, easy, reproducible and quick activity assay to detect CTSS activities in mouse APCs. Since most of basic research on CTSS is performed in mice, this method closes a gap and offers a possibility for reliable and quantitative CTSS activity detection that can be performed in almost every laboratory.

    Detecting cellular activity in sub-millisecond timescale and micrometer resolution without using invasive means has been a long standing goal in the study of cellular networks. Here, we have employed phase sensitive low coherence interferometry for detecting optogenetically stimulated activity of cells. Nanoscale changes in optical path length (due to change in refractive index and changes in cell thickness) occur when cells are activated, which we aim to detect by phase sensitive low coherence interferometry. A low coherence interferometry and patch-clamp electrophysiology systems were integrated with an inverted fluorescence microscope. Blue laser beam was coupled to the electrophysiology-interferometric detection system for optogenetic stimulation. The phase-sensitive measurements were carried out on Channelrhodopsin-2 sensitized cells (identified by YFP fluorescence) as well as control cells in reflection mode for different intensities and exposures of optogenetic stimulation beam. This method offers good temporal and spatial resolution without using exogenous labeling. Results of studies on all optical stimulation and detection of cellular activity will be presented. Interpretation of the optical activity signals will be discussed in context with changes in cell physiology during stimulation. We will also discuss the potential sources of various artifacts in optical/electrical detection of cellular activity during optical stimulation.

    In a partnership last Spring with Arizona Public Service, the National Optical Astronomy Observatory (NOAO) created the 'Dark-Skies Energy Education Program: Energy Awareness for a Sustainable Future'. In this program, experienced science and technology education specialists from NOAO led 2 one-day professional development workshops for thirteen 6th grade teachers on dark skies and energy education. The workshops focused on three foundational, scaffolding activities and a final student research project. This in turn culminated in a Family Science Night where students presented their projects. In between these events, our NOAO team provided support for teachers through real-time video conferencing using FaceTime. In addition to the professional development, each teacher received a kit full of resource materials to perform the activities and research project. The kit was at no cost to the teacher, school, or district. Each kit contained the latest version of a tablet, which was used to facilitate communication and support for the teachers, as well as provide all the program's written teaching materials. The activities are in accordance with state, Common Core and Next Generation Science Standards. Our NOAO instructors gave firsthand experiences on how best to use these materials in a classroom or public setting. They also discussed opportunities on how they can incorporate, adapt and expand upon the activities and research projects in the classroom. Evaluation reports from the program's independent evaluator showed that the students enjoyed learning from the three foundational activities and research projects. The project presentations by the Yuma students were outstanding in their creativity, level of effort, and scientific accuracy. To summarize the evaluations, significant changes in knowledge and attitude were made with the teachers and students (from one-on-one interviews and surveys), but behavioral changes (albeit only over a semester) seemed minimal.

    Nanosensors employing quantum dots (QDs) and enzyme substrates with fluorescent moieties offer tremendous promise for disease surveillance/diagnostics and as high-throughput co-factor assays. Advantages of QDs over other nanoscaffolds include their small size and inherent photochemical properties such as size tunable fluorescence, ease in attaching functional moieties, and resistance to photobleaching. These properties make QDs excellent Förster Resonance Energy Transfer (FRET) donors; well-suited for rapid, optical measurement applications. We report enzyme sensors designed with a single FRET donor, the QD donor acting as a scaffold to multiple substrates or acceptors. The QD-sensor follows the concrete activity of the enzyme, as compared to the most common methodologies that quantify the enzyme amount or its mRNA precursor. As the sensor reports on the enzyme activity in real-time we can actively follow the kinetics of the enzyme. Though classic Michaelis-Menten (MM) parameters can be obtained to describe the activity. In the course of these experiments deviations, both decreasing and increasing the kinetics, from the common MM model were observed upon close examinations. From these observations additional experiments were undertaken to understand the varying mechanisms. Different enzymes can present different deviations depending on the chosen target, e.g. trypsin appears to present a positive hopping mechanism while collagenase demonstrates a QD caused reversible inhibition.

    2016-07-01

    Antigenic peptides presented in the context of major histocompatibility complex (MHC) molecules originate from the degradation of both self and non-self proteins. T cells can therefore recognize at the surface of surveyed cells, the self-peptidome produced by the cell itself (mostly inducing tolerance) or immunogenic peptides derived from exogenous origins. The initiation of adaptive immune responses by dendritic cells (DCs), through the antigenic priming of naïve T cells, is associated to microbial pattern recognition receptors engagement. Activation of DCs by microbial product or inflammatory cytokines initiates multiple processes that maximize DC capacity to present exogenous antigens and stimulate T cells by affecting major metabolic and membrane traffic pathways. These include the modulation of protein synthesis, the regulation of MHC and co-stimulatory molecules transport, as well as the regulation of autophagy, that, all together promote exogenous antigen presentation while limiting the display of self-antigens by MHC molecules.

    The antioxidant and photoprotective activities of dried extracts from the leaves of Encholirium spectabile were investigated. It was also evaluated the total phenolic and flavonoid contents by the Folin–Ciocalteu and aluminum chloride methods, respectively. Antioxidant activities of the extracts were evaluated by using of 2,2-diphenyl-1-picrylhydrazil (DPPH) radical scavenging and β-carotene–linoleic acid bleaching and compared with ascorbic acid, butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) used as reference compounds. The photoprotective effect was evaluated by the spectrophotometric method. The most significant total phenolic and flavonoid contents was of 188.50 ± 27.50 mg of gallic acid equivalent/g and 129.70 ± 4.59 mg of catechin equivalent/g, respectively, for chloroform fraction (Es-CHCl3). The Es-CHCl3 also presented the best antioxidant activity (IC50 25.35 ± 4.35 μg/ml) for DPPH scavenging. The ethanol extract (Es-EtOH), Es-CHCl3 and the fraction ethyl acetate (Es-AcOEt) showed characteristic absorption bands in regions UVB and UVA in a concentration-dependent manner. Es-CHCl3 presented the highest sun protection factor SPF (8.89 ± 2.11). It shows the possibility to use this extract as sunscreen in pharmaceutical preparations. PMID:24396251

    The overall adsorption rate of single micropollutants present in landfill leachates such as phthalic acid (PA), bisphenol A (BPA), diphenolic acid (DPA), 2,4-dichlorophenoxy-acetic acid (2,4-D), and 4-chloro-2-methylphenoxyacetic acid (MCPA) on two commercial activated carbons was studied. The experimental data obtained were interpreted by using a diffusional model (PVSDM) that considers external mass transport, intraparticle diffusion, and adsorption on an active site. Furthermore, the concentration decay data were interpreted by using kinetics models. Results revealed that PVSDM model satisfactorily fitted the experimental data of adsorption rate on activated carbon. The tortuosity factor of the activated carbons used ranged from 2 to 4. The contribution of pore volume diffusion represented more than 92% of intraparticle diffusion confirming that pore volume diffusion is the controlling mechanism of the overall rate of adsorption and surface diffusion can be neglected. The experimental data were satisfactorily fitted the kinetic models. The second-order kinetic model was better fitted the experimental adsorption data than the first-order model. PMID:22858399

    Verifying different sensory modality properties for concepts results in a processing cost known as the modality-switch effect. It has been argued that this cognitive cost is the result of a perceptual simulation. This paper extends this argument and reports an experiment investigating whether the effect is the result of an activation of sensory information which can also be triggered by perceptual linguistically described stimuli. Participants were first exposed to a prime sentence describing a light or a sound's perceptual property (e.g., "The light is flickering", "The sound is echoing"), then required to perform a property-verification task on a target sentence (e.g., "Butter is yellowish", "Leaves rustle"). The content modalities of the prime and target sentences could be compatible (i.e., in the same modality: e.g., visual-visual) or not (i.e., in different modalities). Crucially, we manipulated the stimuli's presentation modality such that half of the participants was faced with written sentences while the other half was faced with aurally presented sentences. Results show a cost when two different modalities alternate, compared to when the same modality is repeated with both visual and aural stimuli presentations. This result supports the embodied and grounded cognition view which claims that conceptual knowledge is grounded into the perceptual system. Specifically, this evidence suggests that sensory modalities can be pre-activated through the simulation of either read or listened linguistic stimuli describing visual or acoustic perceptual properties.

  2. Present-day biogeochemical activities of anaerobic bacteria and their relevance to future exobiological investigations

    If the primordial atmosphere was reducing, then the first microbial ecosystem was probably composed of anaerobic bacteria. However, despite the presence of an oxygen-rich atmosphere, anaerobic habitats are important, commonplace components of the Earth's present biosphere. The geochemical activities displayed by these anaerobes impact the global cycling of certain elements (e.g., C, N, S, Fe, Mn, etc.). Methane provides an obvious example of how human-enhanced activities on a global scale can influence the content of a "radiative" (i.e., infrared absorbing) trace gas in the atmosphere. Methane can be oxidized by anaerobic bacteria, but this does not appear to support their growth. Acetylene, however, does support such growth. This may form the basis for future exobiological investigations of the atmospheres of anoxic, hydrocarbon-rich planets like Jupiter and Saturn, as well as the latter's satellite Titan. ?? 1989.

    The use of extracorporeal techniques for the treatment of paediatric diseases has expanded dramatically in the past decade. Plasmapheresis, a technique for exchanging plasma components with albumin or plasma, has been used in some rheumatologic conditions. We report the clinical course of a 7 years old boy with clinical and biological features of macrophage activation syndrome and multiorgan failure, at the time of presentation of severe juvenile dermatomyositis, and non responsive to corticosteroids, cyclosporine and immunoglobulin. After 4 days in the paediatric intensive care unit, plasmapheresis was used as rescue therapy. Repeated therapeutic plasmapheresis was effective for improving the multiorgan failure and laboratory abnormalities. The patient was discharged on the 21st hospital day with good functional condition. Plasmapheresis should be considered as rescue treatment in patients with life threatening macrophage activation syndrome and systemic onset of juvenile dermatomyositis. PMID:22342516

    In previous studies, it was reported that the protein isolated from the cowpea interferes favourably in lipid metabolism, and reduces cholesterol synthesis. The present study investigated the role of cowpea peptide fractions in the micellar solubilisation of cholesterol, in the 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR) activity, and in the in vitro antioxidant capacity, considering the effects of thermal processing. The protein was isolated from the raw and cooked beans and digested to simulate human digestion. The peptides from the protein isolate of raw bean with molecular mass lower than 3kDa reduced 89% of the HMGCR enzymatic reaction velocity. The cooked cowpeas were more effective in inhibiting the micellar solubility of cholesterol than the raw ones but not the antioxidant activity. This is the first report that cowpea peptides inhibit cholesterol homeostasis in vitro in two distinct routes, and act as an antioxidant.

  5. Deciphering the Long-Term Trend of Atlantic Basin Intense Hurricanes: More Active Versus Less Active During the Present Epoch

    1998-01-01

    During the interval of 1944-1997, 120 intense hurricanes (i.e., those of category 3 or higher on the Saffir-Simpson hurricane damage potential scale) were observed in the Atlantic basin, having an annual frequency of 0-7 events per year, being more active prior to the mid 1960's than thereafter (hence a possible two-state division: more active versus less active), and being preferentially lower during El Nino years as compared to non-El Nino years. Because decadal averages of the frequency of intense hurricanes closely resemble those of average temperature anomalies for northern hemispheric and global standards and of the average temperature at the Armagh Observatory (Northern Ireland), a proxy for climatic change, it is inferred that the long-term trends of the annual frequency of intense hurricanes and temperature may be statistically related. Indeed, on the basis of 4- and 10-yr moving averages, one finds that there exists strong linear associations between the annual frequency of intense hurricanes in the Atlantic basin and temperature (specially, when temperature slightly leads). Because the long-term leading trends of temperature are now decidedly upward, beginning about the mid 1980's, it is inferred that the long-term consequential trends of the annual frequency of intense hurricanes should now also be upward, having begun near 1990, suggesting that a return to the more active state probably has already occurred. However, because of the anomalous El Nino activity of the early to mid 1990's, the switch from the less active to the more active state essentially went unnoticed (a marked increase in the number of intense hurricanes was not observed until the 1995 and 1996 hurricane seasons, following the end of the anomalous El Nino activity). Presuming that a return to the more active state has, indeed, occurred, one expects the number of seasonal intense hurricanes during the present epoch (continuing through about 2012) to usually be higher than average (i

    In previous studies, we have emphasized the importance of considering the methods used for analysis of gingival crevicular fluid (GCF). This study evaluated 4 different approaches for data presentation of lysosomal enzyme activity in GCF. GCF was collected from patients displaying at least 2 mm of clinical attachment loss at a minimum of 3 sites in the mouth (DA), and patients who did not display clinical attachment loss of 2 mm or more at any site in the mouth (DI), during a 3-month interval following entry into a longitudinal trial. GCF was collected by the timed intrasulcular placement of precut filter paper strips. 16 to 28 individual GCF samples were collected from each patient. The lysosomal enzymes studied were B-glucuronidase (BG) and arylsulfatase. The mean values for the DA and DI groups at baseline and 3 months are reported. The results indicate that when the data is expressed as total enzyme activity (unit activity) per 30-s collection (UA) or UA x GCF volume (microliter) per mm of probing depth, the DA group demonstrated significantly greater mean values than the DI group at baseline and 3 months. In contrast, when the data was expressed as concentration (UA/microliter), or UA per mm of probing depth, differences between the DA and DI groups were observed only at the 3-month evaluation. The difficulty in using concentration when reporting GCF lysosomal enzyme activity is emphsized by comparison of the data from the DA group and the high and low enzyme activity subsets of the DI group.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3042812

    Fruit from the palm Mauritia flexuosa is one of the most important species in Peru, Venezuela, Brazil, Colombia, Bolivia, and Guyana. The present study aimed to investigate the antiplatelet and antithrombotic activities of oil extracted from Mauritia flexuosa. The fatty acid contents were determined by gas chromatography-mass spectrometry. Oil extract of peel of Mauritia flexuosa was extracted by soxhlet extraction. The oil extract inhibited platelet secretion and aggregation induced by ADP, collagen, and TRAP-6 by a concentration-dependent way (0.1 to 1 mg/mL) without the participation of the adenylyl cyclase pathway and diminished platelet rolling and firm adhesion under flow conditions. Furthermore, the oil extract induced a marked increase in the rolling speed of leukocytes retained on the platelet surface, reflecting a reduction of rolling and less adhesion. At the concentrations used, the oil extract significantly decreased platelet release of sP-selectin, an atherosclerotic-related inflammatory mediator. Oil extract inhibited thrombus growth at the same concentration as that of aspirin, a classical reference drug. Finally, the data presented herein also demonstrate for the first time to our knowledge the protective effect of oil extracted from Mauritia flexuosa on platelet activation and thrombosis formation.

    The aim of this study was to evaluate whether the objective structured clinical examination (OSCE) and case presentation (CP) as forms of active assessment were effective measures of overall didactic knowledge and clinical performance in a predoctoral dental curriculum. This evaluation was conducted by statistical analysis of quality points (QP) awarded for didactic and clinical performance, CP grades, and OSCE scores for 185 students at Harvard School of Dental Medicine who graduated during the period 2010-14. As part of the requirements for graduation, each student takes three OSCEs and presents two patient cases. Data for the study were obtained from the Office of the Registrar. The results showed no direct correlation between QP and CP grades and no correlation between CP grades and OSCE scores. However, there was a correlation between OSCE scores and QP. Students with honors-level scores on any of the three OSCEs received significantly more QP than students who did not receive honors. In addition, students with passing scores on OSCEs 2 and 3 received significantly more QP than students with failing or marginal OSCE scores. Innovative formats of active assessment such as OSCEs and CPs can promote a student-centered learning environment. These data indicated that, within this study population, there was a positive association between OSCE scores and clinical and didactic performance, supporting the value of OSCEs as a means of assessment.

    The functionalization of polymeric nanoparticles with ligands that target specific receptors on immune cells offers the opportunity to tailor adjuvant properties by conferring pathogen mimicking attributes to the particles. Polyanhydride nanoparticles are promising vaccine adjuvants with desirable characteristics such as immunomodulation, sustained antigen release, activation of antigen presenting cells, and stabilization of protein antigens. These capabilities can be exploited to design nanovaccines against viral pathogens, such as HIV-1, due to the important role of dendritic cells and macrophages in viral spread. In this work, an optimized process was developed for carbohydrate functionalization of HIV-1 antigen-loaded polyanhydride nanoparticles. The carbohydrate-functionalized nanoparticles preserved antigenic properties upon release and also enabled sustained antigen release kinetics. Particle internalization was observed to be chemistry-dependent with positively charged nanoparticles being taken up more efficiently by dendritic cells. Up-regulation of the activation makers CD40 and CD206 was demonstrated with carboxymethyl-α-d-mannopyranosyl-(1,2)-d-mannopyranoside functionalized nanoparticles. The secretion of the cytokines IL-6 and TNF-α was shown to be chemistry-dependent upon stimulation with carbohydrate-functionalized nanoparticles. These results offer important new insights upon the interactions between carbohydrate-functionalized nanoparticles and antigen presenting cells and provide foundational information for the rational design of targeted nanovaccines against HIV-1.

    It has been proposed that declarative memories can be dependent on both an episodic and a semantic memory system. While the semantic system deals with factual information devoid of reference to its acquisition, the episodic system, characterized by mental time travel, deals with the unique past experience in which an event took place. Episodic memory is characteristically hippocampus-dependent. Place cells are recorded from the hippocampus of rodents and their firing reflects many of the key characteristics of episodic memory. For example, they encode information about "what" happens "where," as well as temporal information. However, when these features are expressed during an animal's behavior, the neuronal activity could merely be categorizing the present situation and could therefore reflect semantic memory rather than episodic memory. We propose that mental time travel is the key feature of episodic memory and that it should take a form, in the awake animal, similar to the replay of behavioral patterns of activity that has been observed in hippocampus during sleep. Using tasks designed to evoke episodic memory, one should be able to see memory reactivation of behaviorally relevant sequences of activity in the awake animal while recording from hippocampus and other cortical structures.

    Previous work developing particle-based acellular, artificial antigen presenting cells (aAPCs) has focused exclusively on spherical platforms. To explore the role of shape, we generated ellipsoidal PLGA microparticles with varying aspect ratios (ARs) and synthesized aAPCs from them. The ellipsoidal biomimetic aAPCs with high-AR showed significantly enhanced in vitro and in vivo activity above spherical aAPCs with particle volume and antigen content held constant. Confocal imaging indicates that CD8+ T cells preferentially migrate to and are activated by interaction with the long axis of the aAPC. Importantly, enhanced activity of high-AR aAPCs was seen in a mouse melanoma model, with high-AR aAPCs improving melanoma survival compared to non-cognate aAPCs (p = 0.004) and cognate spherical aAPCs (p = 0.05). These findings indicate that particle geometry is a critical design criterion in the generation of aAPCs, and may offer insight into the essential role of geometry in the interaction between CD8+ T cells and biological APCs.

    We report on the present and future detector development activities for the European Space Agency Science Programme. The development of European technology in that field is a key mission enabler for the program, which requires TRL6 (ISO scale) by end of the definition phase, so called "mission adoption". This is particularly true for Astronomy and fundamental physics type missions. Current activities are in particular targeting large format and p-channel CCD, NIR and MWIR, LWIR wavelength ranges as well as related ASIC controller. For the longer term future mission plan (so called M4, M5 and L2 missions, M3 being PLATO and L1 JUICE), the extreme ends of the spectrum will be addressed. An overview of the detector status for the Earth Observation program is given in appendix, as most of the technologies are directly applicable to some extent to science missions, in particular for Planetary missions. The specific validation activities in place in the future mission preparation office in support to the space science program will be eventually briefly detailed.

    Since the Tortonian, the thinned continental crust and the overlying sedimentary cover of the Alboran Sea are submitted to tectonic inversion due to the convergence between Eurasia and Africa. The past and present deformation is significant along the Moroccan margin where the MARLBORO-1 cruise in 2011, acquired 1100 km of mid-resolution seismic reflection along 20 profiles perpendicular and parallel to the margin, off Al Hoceima, to latitude 36°N. The study area located on the Xauen/Tofino banks and the South Alboran ridge off Morocco, shows signs of both past and present strong tectonic deformation, mass-movement deposits (mostly slides and mass flow deposits), and contourites. The lateral and longitudinal evolution of contourites and mass movement deposits and the geometric relationships between those deposits and active tectonic structures have been studied. In the distal margin, contourites and gravitational instabilities are the depositional systems that best record the tectonic signal of the area since at least the Messinian. On the two flanks of the Xauen/Tofino and South Alboran ridge, the sedimentary register affected by growth-faults is mainly composed of contourites. Internal strata pattern, spatial and temporal distribution of thickness and depocenters, and discontinuities help to infer sedimentary processes and their interaction with tectonics. In the southern Alboran Sea where the bathymetry shows abrupt slopes, the recurrent seismic activity seems to be the main factor triggering mass wasting as witnessed by the Mass transport complexes (MTCs). Recent MTCs originate from escarpments on the edge of the contourites. However, in most cases the seismic reflection data show the depositional bodies of numerous slides linked to the activity of growth-faults and thrusts observed on the Xauen and Tofino Bank's north flanks. Tectonic inversion is recorded since the late Miocene with an acceleration of the uplift and compressional activity evidenced during

    Aging can be viewed as a quasi-programmed phenomenon driven by the overactivation of the nutrient-sensing mTOR gerogene. mTOR-driven aging can be triggered or accelerated by a decline or loss of responsiveness to activation of the energy-sensing protein AMPK, a critical gerosuppressor of mTOR. The occurrence of age-related diseases, therefore, reflects the synergistic interaction between our evolutionary path to sedentarism, which chronically increases a number of mTOR activating gero-promoters (e.g., food, growth factors, cytokines and insulin) and the “defective design” of central metabolic integrators such as mTOR and AMPK. Our laboratories at the Bioactive Food Component Platform in Spain have initiated a systematic approach to molecularly elucidate and clinically explore whether the “xenohormesis hypothesis,” which states that stress-induced synthesis of plant polyphenols and many other phytochemicals provides an environmental chemical signature that upregulates stress-resistance pathways in plant consumers, can be explained in terms of the reactivity of the AMPK/mTOR-axis to so-called xenohormetins. Here, we explore the AMPK/mTOR-xenohormetic nature of complex polyphenols naturally present in extra virgin olive oil (EVOO), a pivotal component of the Mediterranean style diet that has been repeatedly associated with a reduction in age-related morbid conditions and longer life expectancy. Using crude EVOO phenolic extracts highly enriched in the secoiridoids oleuropein aglycon and decarboxymethyl oleuropein aglycon, we show for the first time that (1) the anticancer activity of EVOO secoiridoids is related to the activation of anti-aging/cellular stress-like gene signatures, including endoplasmic reticulum (ER) stress and the unfolded protein response, spermidine and polyamine metabolism, sirtuin-1 (SIRT1) and NRF2 signaling; (2) EVOO secoiridoids activate AMPK and suppress crucial genes involved in the Warburg effect and the self-renewal capacity of

    We investigated the aerobic and anaerobic benefits of high-intensity interval training performed at a work-to-rest ratio of 1:2 because little performance enhancement data exist based on this ratio. Recreationally active male volunteers (21 years, 184 cm, 81.5 kg) were randomly assigned to a training (interval training [IT] n = 10) or control group (n = 11). Baseline assessments were repeated after the last training session. Each participant underwent basic anthropometric assessment and performed a VO2max test on an electronically braked cycle ergometer and a 30-second Wingate test. Venous samples were acquired at the antecubital vein and subsequently processed for lactate (LA); samples were obtained at rest, and 5 and 15-minute post-Wingate test. The interval training used a cycling power output equivalent to 80% of VO2max (80% p VO2max) applied for 6 90-second bouts (each followed by 180-second rest) per session, 3 sessions per week, for 6 weeks. The control group maintained their normal routine for the 6-week period. Group × time repeated-measures analyses of variance revealed that IT improved VO2max (5.5 ml · kg(-1) · min), anaerobic threshold (3.8 ml · kg(-1) · min), work output (12.5 J · kg(-1)), glycolytic work (11.5 J · kg(-1)), mean power (0.3 W · kg), peak power (0.4 W · kg(-1)), and max power (0.4 W · kg(-1)); p < 0.05. Posttesting LA was lower on average for IT at the 5-minute mark but significantly so at the 15-minute mark. Twenty-seven minutes of cycling at 80% p VO2max applied with a work-to-rest ratio of 1:2 and spread over 3 sessions per week for 6 weeks provided sufficient stimulus to significantly improve markers of anaerobic and aerobic performance in recreationally active college-aged men. Inclusion of such a protocol into a training program may rapidly restore or improve a client's or athlete's maximal functional capacity.

    During human exploration of the lunar surface, a suited crewmember needs effective and accurate information about consumable levels remaining in their life support system. The information must be presented in a manner that supports real-time consumable monitoring and route planning. Since consumable usage is closely tied to metabolic rate, the lunar suit must estimate metabolic rate from life support sensors, such as oxygen tank pressures, carbon dioxide partial pressure, and cooling water inlet and outlet temperatures. To provide adequate warnings that account for traverse time for a crewmember to return to a safe haven, accurate forecasts of consumable depletion rates are required. The forecasts must be presented to the crewmember in a straightforward, effective manner. In order to evaluate methods for displaying consumable forecasts, a desktop-based simulation of a lunar Extravehicular Activity (EVA) has been developed for the Constellation lunar suite s life-support system. The program was used to compare the effectiveness of several different data presentation methods.

    People who live with mental illnesses are among the most stigmatized groups in society. In 1996, in recognition of the particularly harsh burden caused by the stigma associated with schizophrenia, the WPA initiated a global anti-stigma program, Open-the-Doors. In 2005, a WPA Section on Stigma and Mental Health was created, with a broader mandate to reduce stigma and discrimination caused by mental disabilities in general. In light of these impor-tant developments, and the growing public health interest in stigma reduction, this paper reflects on the past perspectives that have led us to our current position, reviews present activities and accomplishments, and identifies challenges that the Section members will face in their future efforts to reduce the stigma caused by mental disorders.

    This talk will introduce a new nanotechnology platform for cancer combination therapy that utilizes near infrared light activation not only for photodynamic damage but also as an extrinsic mechanism to initiate release of complimentary drugs to suppress dynamic bursts in molecular signaling networks that promote tumor cell survival and treatment escape. The goal is to achieve co-delivery with concomitant activity of photodynamic, molecular inhibitor and chemotherapeutic agents, selectively within the tumor. This approach overcomes challenges in achieving synergistic interactions using sequential drug delivery. Conventional drug delivery is compromised by the differential pharmacokinetics of individual agents and potentially antagonistic effects—such as vascular shutdown by one agent that limits delivery of the second. Here, photodynamic damage—which efficiently kills drug-resistant cells via damage of common proteins involved in drug-resistance (such as anti-apoptosis factors and drug-efflux transporters)—is synchronized spatially and temporally with the photo-initiated release of complimentary agents—to enable full interaction amongst the individual therapies. This spatiotemporal synchronization offers new prospects for exploiting time-sensitive synergistic interactions. Specific implementations of these concepts will be presented in preclinical models of cancer. Strategies to enable molecular-targeting of cancer cells via site-specific attachment of targeting moieties to the outer lipid shell of these nanovehicles will also be discussed. If successful in humans, this new paradigm for synchronized, tumor-focused combination therapy will ultimately supersede the present use of chronic drug injection by increasing efficacy per cycle whilst reducing systemic exposure to toxic drugs.

  5. 21st Century Extravehicular Activities: Synergizing Past and Present Training Methods for Future Spacewalking Success

    Neil Armstrong's understated words, "That's one small step for man, one giant leap for mankind." were spoken from Tranquility Base forty years ago. Even today, those words resonate in the ears of millions, including many who had yet to be born when man first landed on the surface of the moon. By their very nature, and in the the spirit of exploration, extravehicular activities (EVAs) have generated much excitement throughout the history of manned spaceflight. From Ed White's first space walk in June of 1965, to the first steps on the moon in 1969, to the expected completion of the International Space Station (ISS), the ability to exist, live and work in the vacuum of space has stood as a beacon of what is possible. It was NASA's first spacewalk that taught engineers on the ground the valuable lesson that successful spacewalking requires a unique set of learned skills. That lesson sparked extensive efforts to develop and define the training requirements necessary to ensure success. As focus shifted from orbital activities to lunar surface activities, the required skill-set and subsequently the training methods, changed. The requirements duly changed again when NASA left the moon for the last time in 1972 and have continued to evolve through the Skylab, Space Shuttle; and ISS eras. Yet because the visits to the moon were so long ago, NASA's expertise in the realm of extra-terrestrial EVAs has diminished. As manned spaceflight again shifts its focus beyond low earth orbit, EVA success will depend on the ability to synergize the knowledge gained over 40+ years of spacewalking to create a training method that allows a single crewmember to perform equally well, whether performing an EVA on the surface of the Moon, while in the vacuum of space, or heading for a rendezvous with Mars. This paper reviews NASA's past and present EVA training methods and extrapolates techniques from both to construct the basis for future EVA astronaut training.

    The functionalization of polymeric nanoparticles with ligands that target specific receptors on immune cells offers the opportunity to tailor adjuvant properties by conferring pathogen mimicking attributes to the particles. Polyanhydride nanoparticles are promising vaccine adjuvants with desirable characteristics such as immunomodulation, sustained antigen release, activation of antigen presenting cells (APCs), and stabilization of protein antigens. These capabilities can be exploited to design nanovaccines against viral pathogens, such as HIV-1, due to the important role of dendritic cells (DCs) and macrophages in viral spread. In this work, an optimized process was developed for carbohydrate functionalization of HIV-1 antigen-loaded polyanhydride nanoparticles. The carbohydrate-functionalized nanoparticles preserved antigenic properties upon release and also enabled sustained antigen release kinetics. Particle internalization was observed to be chemistry-dependent with positively charged nanoparticles being taken up more efficiently by DCs. Up-regulation of the activation makers CD40 and CD206 was demonstrated with carboxymethyl-α-d-mannopyranosyl-(1,2)-d-mannopyranoside functionalized nanoparticles. The secretion of the cytokines IL-6 and TNF-α was shown to be chemistry-dependent upon stimulation with carbohydrate-functionalized nanoparticles. These results offer important new insights upon the interactions between carbohydrate-functionalized nanoparticles and APCs and provide foundational information for the rational design of targeted nanovaccines against HIV-1.

    trends and variations in gully size, morphology, orientation, and location are additionally examined as indications of a seasonal (or other) control, as well as variations with latitude, dune type/size/orientation, or Mars year. This presentation will summarize the results of our monitoring campaigns, and will compare the data that are available about gullies of different morphologies and locations. Our aim is to identify possible similarities (and differences) in gully activity processes across Mars, and to estimate the rates of gully formation and modification processes (as has been done for gullies in the southern mid-latitudes [3]). Such estimates would aid interpretation of the likely ages of observed gullies, which have implications for whether records of past (and potential aqueous) gully formation processes are still observable.

  8. Artificial antigen presenting cell (aAPC) mediated activation and expansion of natural killer T cells.

    PubMed

    East, James E; Sun, Wenji; Webb, Tonya J

    2012-01-01

    Natural killer T (NKT) cells are a unique subset of T cells that display markers characteristic of both natural killer (NK) cells and T cells(1). Unlike classical T cells, NKT cells recognize lipid antigen in the context of CD1 molecules(2). NKT cells express an invariant TCRα chain rearrangement: Vα14Jα18 in mice and Vα24Jα18 in humans, which is associated with Vβ chains of limited diversity(3-6), and are referred to as canonical or invariant NKT (iNKT) cells. Similar to conventional T cells, NKT cells develop from CD4-CD8- thymic precursor T cells following the appropriate signaling by CD1d (7). The potential to utilize NKT cells for therapeutic purposes has significantly increased with the ability to stimulate and expand human NKT cells with α-Galactosylceramide (α-GalCer) and a variety of cytokines(8). Importantly, these cells retained their original phenotype, secreted cytokines, and displayed cytotoxic function against tumor cell lines. Thus, ex vivo expanded NKT cells remain functional and can be used for adoptive immunotherapy. However, NKT cell based-immunotherapy has been limited by the use of autologous antigen presenting cells and the quantity and quality of these stimulator cells can vary substantially. Monocyte-derived DC from cancer patients have been reported to express reduced levels of costimulatory molecules and produce less inflammatory cytokines(9,10). In fact, murine DC rather than autologous APC have been used to test the function of NKT cells from CML patients(11). However, this system can only be used for in vitro testing since NKT cells cannot be expanded by murine DC and then used for adoptive immunotherapy. Thus, a standardized system that relies on artificial Antigen Presenting Cells (aAPC) could produce the stimulating effects of DC without the pitfalls of allo- or xenogeneic cells(12, 13). Herein, we describe a method for generating CD1d-based aAPC. Since the engagement of the T cell receptor (TCR) by CD1d-antigen complexes is

    Selectivity to insects over mammals is one of the important characteristics for a chemical to become a useful insecticide. Fipronil was found to block cockroach GABA receptors more potently than rat GABAA receptors. Furthermore, glutamate-activated chloride channels (GluCls), which are present in cockroaches but not in mammals, were very sensitive to the blocking action of fipronil. The IC50s of fipronil block were 30 nM in cockroach GABA receptors and 1600 nM in rat GABAA receptors. Moreover, GluCls of cockroach neurons had low IC50s for fipronil. Two types of glutamate-induced chloride current were obswerved: desensitizing and non-desensitizing, with fipronil IC50s of 800 and 10 nM, respectively. We have developed methods to separately record these two types of GluCls. The non-desensitizing and desensitizing currents were selectively inhibited by trypsin and polyvinylpyrrolidone, respectively. In conclusion, in addition to GABA receptors, GluCls play a crucial role in selectivity of fipronil to insects over mammals. GluCls form the basis for development of selective and safe insecticides.

  15. Hostility and social support explain physical activity beyond negative affect among young men, but not women, in college.

    PubMed

    Maier, Karl J; James, Ashley E

    2014-01-01

    We examined social support as a moderator of cynical hostility in relation to physical activity and body mass index among college students (n = 859; M = 18.71 years (SD = 1.22); 60% women, 84% White). After controlling for negative affect in hierarchical linear regression models, greater hostility was associated with lesser physical activity among those with low social support, as expected. Greater hostility was also associated with greater physical activity among those high in social support, ps < .05. Effects were observed for men only. Hostility and social support were unrelated to body mass index, ps > .05. Young men with a hostile disposition and low social support may be at risk for a sedentary lifestyle for reasons other than negative affect.

  16. Solifluction activity in the present periglacial belt of Sierra Nevada during the last 8 ky BP

    Oliva, M.; Schulte, L.; Gómez Ortiz, A.

    2009-04-01

    Solifluction records in Sierra Nevada (Andalusia, Spain) reveal a succession of environmental changes during the last millennia in this massif mostly related to Holocene climate dynamics. Geomorphological processes in Sierra Nevada react sensitively to small changes in temperature or moisture regimes, showing the proximity of these processes to their climate boundaries and the small climate range necessary to carry environmental changes in the summits of this massif. Solifluction dynamics in Sierra Nevada is influenced by a complex interaction between environmental factors (slope, vegetation cover, texture) and climate parameters (ground thermal regime, length and thickness of the snow cover, water supply). Interdependant feed-back mechanisms among all these variables make difficult to understand the key factors involved in present and past solifluction processes, although monitoring control performed on lobes with different emplacements suggest today's favourable environmental conditions for solifluction displacements. Water availability controls both vegetation cover and slope processes. In fact, currently water supply determines the grass cover in gentle valley floors, but it is also decisive to provide water for the small solifluction displacements detected during the monitored period. Thermal conditions also play a decisive role to activate solifluction or soil formation with similar moisture regimes. The very weak activity pattern of hundreds of solifluction lobes suggests that they must have developed in other more favourable climate conditions. We studied more than 30 sedimentological profiles from solifluction lobes in San Juan and Rio Seco valleys, which reveal an alternation of solifluction/edaphic cycles during the Holocene, with nine different geomorphic phases in the highest western cirques of Sierra Nevada. In San Juan valley, north exposed, there are several generations of solifluction lobes covering the last 8-9 ky BP, while in the southern Rio

  17. Investigating the present and past glacial and frost activity on Pluto with a volatile transport model

    NASA Astrophysics Data System (ADS)

    Bertrand, Tanguy; Forget, Francois

    2016-10-01

    The high obliquity and eccentricity of the orbit of Pluto induce seasonal cycles of condensation and sublimation of the main volatile ices: N2, CH4, and CO. The New Horizons spacecraft, which flew by Pluto in July 2015, revealed a complex surface composition including a thousand-kilometre nitrogen glacier in the "Sputnik Planum" plain near the Anti-Charon longitude, extensive methane frosts at mid and high latitudes, and equatorial ice-free regions. We present numerical simulations designed to model the evolution of Pluto's volatiles over thousands of years on the basis of straightforward universal physical equations.Our results explain the observed distribution of ices on the surface and the quantities of volatiles in the atmosphere. In particular the model predicts the N2 ice accumulation in the deepest low-latitude basin and the 3-fold increase of pressure observed to occur since 1988. This points to atmospheric-topographic processes at the origin of the Sputnik Planum's nitrogen glacier. The same simulations also show frosts of methane, and sometimes nitrogen, that seasonally cover the mid and high latitudes, explaining the bright northern polar cap reported in the 1990s and the observed ice distribution in 2015. The model also predicts that most of these seasonal frosts should disappear in the next decade, and thus could be tested observationally in the near future.Using prior orbital parameters of Pluto and a realistic glacial flow parametrization, we also simulate past climates of Pluto. The results show that Pluto undergoes cycles of glacial activity (over timescales of few million years) that may explain the rugged eroded-mountain landscapes surrounding Sputnik Planum and the "bladed" methane terrains east of "Tombaugh Regio".

  18. Present-Day Seasonal Gully Activity in a South Polar Pit (Sisyphi Cavi) on Mars

    2014-05-01

    Seasonal activity of gullies under current climatic conditions on Mars was observed by [1-7]. Dundas et al. [2] reviewed the present-day activity of classical gullies (including the gully presented in this work), dune gullies, and other mass wasting processes in the southern hemisphere on Mars. Recent polar gullies in Sisyphi Cavi were also analyzed by [8], who estimated ages of about 20 ka to 20 Ma for the gullies. In this study we focus on a single gully in Sisyphi Cavi, located in the south polar region at 1.44° E and 68.54° S. The gully occurs on the gullied equator-facing slope of an isolated polar pit within an infilled impact crater. Multi-temporal high-resolution image data analyses show new deposits at the terminus of the gully channel and on the gully apron within spring (after solar longitudes of 236°) of martian years (MY) 29 and 31. In MY 29 deposition of material shortens the channel by about 40 m; in MY 31 a new deposit at the western flank of the gully apron with approximately 300-600 m3 of material is visible [3]. Our morphological investigations show that the identified new deposits were formed by dark flows through the entire gully deposited on top of the apron between LS ~218° and ~226°. Thermal data show a temperature increase between solar longitudes (LS) ~218° and ~226°. Near-infrared spectral data show relatively constant band strengths of CO2 ice and H2O ice in this time range. After the formation of the dark flows (after LS ~226°), temperatures increase rapidly from ~180 K to >~270 K at LS ~250°. At this time, spectral data indicate that all volatiles on the surface sublimated. However, an earlier beginning of sublimation when the dark flows were observed (between LS ~218° and ~226°) is likely, due to the fact that the instruments can only show the last phase of sublimation (decrease of volatile band strengths) [3]. Spectral modeling shows that from winter to mid-spring, the surface of the studied area is covered by CO2 slab

    Nontraditional college students (older, part-time, and/or working) have less healthful nutrition and physical activity behaviors compared to traditional students, yet few health promotion efforts focus on nontraditional students. The purpose of this study was to use qualitative methods to explore factors affecting nutrition and physical activity behaviors of nontraditional students. Fourteen semi-structured individual interviews were conducted with nontraditional undergraduate students attending a large university. The sample had a median age of 25 (range, 21-64), 57% were men, 43% were racial/ethnic minorities, and 57% were employed (mean 22 hours/week). Data were coded using a systematic team-based approach. Consistent themes (mentioned by 4+ students) were identified and categorized into three domains: home, work, and school. Home (themes: neighborhood characteristics, family, partners), work (theme: work environment), and school (themes: cafeteria, vending machines) factors consistently influenced positive nutrition behaviors. Similarly, home (themes: neighborhood including safety, friends from home, partner,), work (theme: work environment), and school (themes: not having a car, campus structure, campus gym, friends at school) factors consistently influenced positive physical activity. Financial resources and perceptions of autonomy had influence across domains. Results indicate consistent influences on nutrition and physical activity behaviors across home, work, and school domains for nontraditional college students. Study findings suggest possible, and sometimes unconventional, intervention strategies to promote healthful eating and physical activity. For example, when cafeteria meal plans are not offered and financial constraints limit eating at the cafeteria, encouraging healthful choices from vending machines could be preferable to not eating at all.

    Heteroxylans in the plant cell wall have been proposed to have a role analogous to that of xyloglucans or heteromannans, forming growth-restraining networks by interlocking cellulose microfibrils. A xylan endotransglycosylase has been identified that can transglycosylate heteroxylan polysaccharides in the presence of xylan-derived oligosaccharides. High activity was detected in ripe fruit of papaya (Carica papaya), but activity was also found in a range of other fruits, imbibed seeds and rapidly growing seedlings of cereals. Xylan endotransglycosylase from ripe papaya fruit used a range of heteroxylans, such as wheat arabinoxylan, birchwood glucuronoxylan and various heteroxylans from dicotyledonous primary cell walls purified from tomato and papaya fruit, as donor molecules. As acceptor molecules, the enzyme preferentially used xylopentaitol over xylohexaitol or shorter-length acceptors. Xylan endotransglycosylase was active over a broad pH range and could perform transglycosylation reactions up to 55 °C. Xylan endotransglycosylase activity was purified from ripe papaya fruit by ultrafiltration and cation exchange chromatography. Highest endotransglycosylase activity was identified in fractions that also contained high xylan hydrolase activity and correlated with the presence of the endoxylanase CpaEXY1. Recombinant CpaEXY1 protein transiently over-expressed in Nicotiana benthamiana leaves showed both endoxylanase and xylan endotransglycosylase activities in vitro, suggesting that CpaEXY1 is a single enzyme with dual activity in planta. Purified native CpaEXY1 showed two- to fourfold higher endoxylanase than endotransglycosylase activity, suggesting that CpaEXY1 may act primarily as a hydrolase. We propose that xylan endotransglycosylase activity (like xyloglucan and mannan endotransglycosylase activities) could be involved in remodelling or re-arrangement of heteroxylans of the cellulose-non-cellulosic cell wall framework.

    The venom of Echis multisquamatus (Central Asian sand viper) contains a single prothrombin activator, designated multisquamase, which is structurally and functionally different from ecarin, the prothrombin activator from the venom of Echis carinatus (saw-scaled viper). Multisquamase is comprised of a 58000 Mr and a 23000 Mr subunit that consists of two disulfide-linked chains of 12000 Mr and 10000 Mr, respectively. In contrast to ecarin, which activates prothrombin and prethrombin 1 at comparable rates, and whose activity is hardly affected by Ca2+ or by changes in ionic strength, multisquamase hardly activates prethrombin 1; prothrombin activation requires Ca2+ and is strongly inhibited at high ionic strength. The most favourable kinetic parameters are observed at 1 mM Ca2+ and at low ionic strength (Km=0.085 microM and kcat=0.68 s(-1) at I approximately 0.04). An increase in ionic strength considerably reduces the rate of prothrombin activation, due to an increase of the Km (Km=0.8 microM and kcat=1.03 s(-1) at I approximately 0.2). Studies in plasmas from patients on oral anticoagulant therapy show that E. Multisquamatus venom only activates carboxylated prothrombin, whereas E. carinatus activates both prothrombin and descarboxyprothrombin. Thus, multisquamase-dependent prothrombin activation appears to require post-translational modification of the gla-domain. This venom prothrombin activator may, therefore, become a useful tool to quantitate prothrombin and descarboxyprothrombin in cases where vitamin K-dependent carboxylation of prothrombin is impaired.

    There has been tremendous growth in the field of active matter, where the individual particles that comprise the system are self-driven. Examples of this class of system include biological systems such as swimming bacteria and crawling cells. More recently, non-biological swimmers have been created using colloidal Janus particles that undergo chemical reactions on one side to produce self-propulsion. These active matter systems exhibit a wide variety of behaviors that are absent in systems undergoing purely thermal fluctuations, such as transitions from uniform liquids to clusters or living crystals, pushing objects around, ratchet effects, and phase separation in mixtures of active and passive particles. Here we examine the collective effects of active matter disks in the presence of static or dynamic substrates. For colloids, such substrates could be created optically in the form of periodic, random, or quasiperiodic patterns. For thermal particles, increasing the temperature generally increases the diffusion or mobility of the particles when they move over a random or periodic substrates. We find that when the particles are active, increasing the activity can increase the mobility for smaller run lengths but decrease the mobility at large run lengths. Additionally we find that at large run lengths on a structured substrate, a variety of novel active crystalline states can form such as stripes, squares and triangular patterns.

    Phloretin and its glycosylated derivatives (phlorizin and phloretin 3',5'-di-C-glucoside) are dihydrochalcones that have many interesting biological properties. The results obtained showed that the dihydrochalcones are able to inhibit growth of Gram positive bacteria, in particular Staphylococcus aureus ATCC 6538, Listeria monocytogenes ATCC 13932 and methicillin-resistant S. aureus clinical strains. Moreover, phloretin is active also against the Gram negative bacteria Salmonella typhimurium ATCC 13311. The determination of the enzymatic activity of key metabolic enzymes allowed us to shed some light on the biochemical mechanism of aglycon cell growth inhibition, showing as it remarkably influences the energetic metabolism of S. aureus. In addition, structure/activity determinations highlighted that the presence of a glycosyl moiety bound to the chalcone structure dramatically decreases the antimicrobial activity of phloretin.

    Hypothesis Neuromuscular inhibition of the infraspinatus would be greater and external rotation muscle force would be lower after a simulated game compared with pregame values. Materials and methods The sample included 21 uninjured, asymptomatic high school–aged baseball pitchers. Maximum volitional shoulder external rotation strength was assessed before and after a simulated game with a clinical dynamometer. Voluntary activation of the infraspinatus was assessed during strength testing by a modified burst superimposition technique. Performance-related fatigue was assessed by monitoring pitch velocity, and global fatigue was assessed by subject self-report before and after the game. Statistical testing included paired and independent t tests, with α ≤ 05. Results There was no difference between throwing and non-throwing shoulder external rotation strength (P = .12) or voluntary infraspinatus activation (P = .27) before the game. After the game, voluntary activation was significantly lower in the throwing limb compared with pregame activation levels (P = .01). Lower external rotation strength after the game approached statistical significance (P =.06). Pitch velocity was lower in the final inning compared with first-inning velocity (P = .01), and fatigue was significantly greater after the game (P = .01). Conclusions Voluntary infraspinatus muscle activation is a mechanism contributing to external rotation muscle weakness in the fatigued pitcher. Understanding mechanisms contributing to muscle weakness is necessary to develop effective injury prevention and rehabilitation programs. Treatment techniques that enhance neuromuscular activation may be a useful strategy for enhancing strength in this population. Level of evidence Basic Science Study, Kinesiology Study. PMID:21831667

    Recently we identified four conjugated glucuronide metabolites of epicatechin, (-)-epicatechin-3'-O-glucuronide (E3'G), 4'-O-methyl-(-)-epicatechin-3'-O-glucuronide (4'ME3'G), (-)-epicatechin-7-O-glucuronide (E7G) and 3'-O-methyl-(-)-epicatechin-7-O-glucuronide (3'ME7G) from plasma and urine. E3'G and 4'ME3'G were isolated from human urine, while E7G and 3'ME7G were isolated from rats that had received oral administration of (-)-epicatechin (Natsume et al. (2003), Free Radic. Biol. Med. 34,840-849). It has been suggested that these metabolites possess considerable in vivo activity, and therefore we carried out a study to compare the antioxidant activities of the metabolites with that of the parent compound. This was achieved by measuring superoxide scavenging activity, reduction of plasma TBARS production and reduced susceptibility of low-density-lipoprotein (LDL) to oxidation. (-)-Epicatechin was found to have more potent antioxidant activity than the conjugated glucuronide metabolites. Both (-)-epicatechin and E7G had marked antioxidative properties with respect to superoxide radical scavenging activity, plasma oxidation induced by 2,2'-azobis-(2-aminopropane) dihydrochloride (AAPH) and LDL oxidation induced by copper ions or 2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile) (MeO-AMVN). In contrast, the other metabolites had light antioxidative activities over the range of physiological concentrations found in plasma.

    Translation of photodynamic therapy to the clinical setting has primarily been limited to easily accessible and/or superficial diseases where traditional light delivery can be performed noninvasively. Cerenkov luminescence, as generated from medically relevant radionuclides, has been suggested as a means to deliver light to deeper tissues noninvasively in order to overcome this depth limitation. We report on the use of Cerenkov luminescence generated from Yttrium-90 as a means to active the photodynamic therapy process in monolayer tumor cell cultures. The current study investigates the utility of Cerenkov luminescence for activating both the clinically relevant aminolevulinic acid at 1.0 mM and also the more efficient photosensitizer TPPS2a at 1.2 µM. Cells were incubated with aminolevulinic acid for 6 hours prior to radionuclide addition, as well as additional daily treatments for three days. TPPS2a was delivered as a single treatment with an 18 hour incubation time before radionuclide addition. Experiments were completed for both C6 glioma cells and MDA-MB-231 breast tumor cells. Although aminolevulinic acid proved ineffective for generating a therapeutic effect at any activity for either cell line, TPPS2a produced at least a 20% therapeutic effect at activities ranging from 6 to 60 µCi/well for the C6 cell line. Current results demonstrate that it may be possible to generate a therapeutic effect in vivo using Cerenkov luminescence to activate the photodynamic therapy process with clinically relevant photosensitizers.

    Deubiquitylating enzymes or DUBs are a class of enzymes that selectively remove the polypeptide posttranslational modification ubiquitin from a number of substrates. Approximately 100 DUBs exist in human cells and are involved in key regulatory cellular processes, which drive many disease states, making them attractive therapeutic targets. Several aspects of DUB biology have been studied through genetic knock-out or knock-down, genomic, or proteomic studies. However, investigation of enzyme activation and regulation requires additional tools to monitor cellular and physiological dynamics. A comparison between genetic ablation and dominant-negative target validation with pharmacological inhibition often leads to striking discrepancies. Activity probes have been used to profile classes of enzymes, including DUBs, and allow functional and dynamic properties to be assigned to individual proteins. The ability to directly monitor DUB activity within a native biological system is essential for understanding the physiological and pathological role of individual DUBs. We will discuss the evolution of DUB activity probes, from in vitro assay development to their use in monitoring DUB activity in cells and in animal tissues, as well as recent progress and prospects for assessing DUB inhibition in vivo.

    The role of the lower extremities and torso is vital in the pitching mechanism. However, a review of the literature reveals information primarily dealing with the upper extremity's role in throwing. This pilot study was conducted to: 1) determine selected lower extremity strength and range of motion measurements in sixteen college baseball pitchers, and 2) compare measurements in the stance leg to the kick leg. When preseason profiling is not possible, clinical norms for those treating college pitchers can be valuable in proper rehabilitation of the lower extremity. Also, by determining trends in lower extremity strength and motion when comparing kick (plant) leg to stance (drive) leg, a better understanding of lower extremity kinematics in the pitching act can be appreciated. Statistically significant differences were found in the active range of motion in plantarflexion, hip internal rotation, and hip extension of the stance leg, as well as hip flexion of the kick leg. lsokinetic evaluations at slow and fast speeds revealed significant differences in the strength of ankle dorsiflexors and hip flexors at slow speeds of the kick leg. Strength of the hamstrings on the kick leg was significant at fast speeds as was strength of the hip external rotators on the stance leg. J Orthop Sports Phys Ther 1986;8(1):10-14.

    Endodontic infections have a polymicrobial nature, but anaerobic bacteria prevail among the infectious microbes. Considering that it is easy to eliminate planktonic bacteria, biofilm-forming bacteria still challenge clinicians during the fight against endodontic diseases. The chemical constituents of the oleoresin of Pinus elliottii, a plant belonging to the family Pinaceae, stand out in the search for biologically active compounds based on natural products with potential application in the treatment of endodontic infections. Indeed, plant oleoresins are an abundant natural source of diterpenes that display significant and well-defined biological activities as well as potential antimicrobial action. In this context, this study aimed to (1) evaluate the in vitro antibacterial activity of the oleoresin, fractions, and subfractions of P. elliottii as well as the action of dehydroabietic acid against 11 anaerobic bacteria that cause endodontic infection in both their planktonic and biofilm forms and (2) assess the in vitro antibiofilm activity of dehydroabietic acid against the same group of bacteria. The broth microdilution technique helped to determine the minimum inhibitory concentration (MIC) of the oleoresin and fractions. This same technique aided determination of the MIC values of nine subfractions of Fraction 1, the most active fraction. The MIC, minimum bactericidal concentration, and antibiofilm activity of dehydroabietic acid against the tested anaerobic bacteria were also examined. The oleoresin and fractions, especially fraction PE1, afforded promising MIC values, which ranged from 0.4 to 50 μg/mL. Concerning the nine evaluated subfractions, PE1.3 and PE1.4 furnished the most noteworthy MIC values, between 6.2 and 100 μg/mL. Dehydroabietic acid displayed antibacterial activity, with MIC values lying from 6.2 to 50 μg/mL, as well as bactericidal effect for all the investigated bacteria, except for Prevotella nigrescens.

    An organic solvent-tolerant lipase from Serratia marcescens ECU1010 (rSML) was overproduced in Escherichia coli in an insoluble form. High concentrations of both biomass (50 g cell wet weight/L culture broth) and inclusion bodies (10.5 g/L) were obtained by applying a high-cell-density cultivation procedure. Activity assays indicated that the enzymatic activity of rSML reached 600 U/L. After treatment with isopropyl ether for 12 h, the maximum lipase activity reached 6,000 U/L. Scanning electron microscopy and Fourier transform infrared microspectroscopy revealed the activation mechanism of rSML in the presence of organic solvents. rSML was stable in broad ranges of temperatures and pH values, as well as in a series of organic solvents. Besides, rSML showed the best enantioselectivity for the kinetic resolution of (±)-trans-3-(4-methoxyphenyl)glycidic acid methyl ester. These features render the S. marcescens ECU1010 lipase attractive for biotechnological applications in the field of organic synthesis and pharmaceutical industry. PMID:23269633

    Episodic hypoxia (EH) is followed by increased ventilatory motor output in the recovery period indicative of long-term facilitation (LTF). We hypothesized that episodic hypoxia evokes LTF of genioglossus (GG) muscle activity in humans during non-rapid eye movement sleep (NREM) sleep. We studied 12 normal non-flow limited humans during stable NREM sleep. We induced 10 brief (3 minute) episodes of isocapnic hypoxia followed by 5 minutes of room air. Measurements were obtained during control, hypoxia, and at 5, 10, 20, 30 and 40 minutes of recovery, respectively, for minute ventilation (V̇I), supraglottic pressure (PSG), upper airway resistance (RUA) and phasic GG electromyogram (EMGGG). In addition, sham studies were conducted on room air. During hypoxia there was a significant increase in phasic EMGGG (202.7±24.1% of control, p<0.01) and in V̇I (123.0±3.3% of control, p<0.05); however, only phasic EMGGG demonstrated a significant persistent increase throughout recovery (198.9±30.9%, 203.6±29.9% and 205.4±26.4% of control, at 5, 10, and 20 minutes of recovery, respectively, p<0.01). In multivariate regression analysis, age and phasic EMGGG activity during hypoxia were significant predictors of EMGGG at recovery 20 minutes. No significant changes in any of the measured parameters were noted during sham studies. Conclusion: 1) EH elicits LTF of GG in normal non-flow limited humans during NREM sleep, without ventilatory or mechanical LTF. 2) GG activity during the recovery period correlates with the magnitude of GG activation during hypoxia, and inversely with age.

    The micro-debris of the size from 100 μm to several mm is expected to cause a spacecraft critical failures and troubles. However, the collision probability of the micro-debris and its effect on space equipment are hardly predicted due to lack knowledge regarding the debris distribution and experimental/numerical investigation on material and components. This paper introduce research and standardization activities related on micro-debris for space environmental prevention

    The melting of permafrost and the associated potential for methane emissions to the atmosphere are major concerns in the context of global warming. However, soils can also represent a significant sink for methane through the activity of methane-oxidizing bacteria (MOB). In this study, we looked at the activity, diversity, and community structure of MOB at two sampling depths within the active layer in three soils from the Canadian high Arctic. These soils had the capacity to oxidize methane at low (15 ppm) and high (1000 ppm) methane concentrations, but rates differed greatly depending on the sampling date, depth, and site. The pmoA gene sequences related to two genotypes of uncultured MOB involved in atmospheric methane oxidation, the 'upland soil cluster gamma' and the 'upland soil cluster alpha', were detected in soils with near neutral and acidic pH, respectively. Other groups of MOB, including Type I methanotrophs and the 'Cluster 1' genotype, were also detected, indicating a broader diversity of MOB than previously reported for Arctic soils. Overall, the results reported here showed that methane oxidation at both low and high methane concentrations occurs in high Arctic soils and revealed that different groups of atmospheric MOB inhabit these soils.

  9. Reduction of hexavalent chromium by Sphaerotilus natans a filamentous micro-organism present in activated sludges.

    Wastewaters produced by various industries may contain undesirable amounts of hexavalent chromium (Cr(VI)), as chromate and dichromate, a hazardous metal affecting flora and animals of aquatic ecosystems as well as human health. One removal strategy comprises the microbial reduction of Cr(VI) to Cr(III), a less soluble chemical species that is less toxic than Cr(VI). In this work, the ability to reduce Cr(VI) of Sphaerotilus natans, a filamentous bacterium usually found in activated sludge systems, was evaluated. In aerobic conditions, S. natans was able to efficiently reduce Cr(VI) to Cr(III) from dichromate solutions ranging between 4.5 and 80 mg Cr(VI)l(-1) in the presence of a carbonaceous source. A simultaneous evaluation of the microbial respiratory activity inhibition was also carried out to analyze the toxic effect of Cr(VI). Cr(VI) reduction by S. natans was mathematically modeled; chromium(VI) reduction rate depended on both Cr(VI) concentration and active biomass concentration. Although it is known that S. natans removes heavy metal cations such as Cr(III) by biosorption, the ability of this micro-organism to reduce Cr(VI), which behaves as an oxyanion in aqueous solutions, is a novel finding. The distinctive capacity to reduce Cr(VI) to Cr(III) than remain soluble or precipitated becomes S. natans a potential micro-organism to decontaminate wastewaters.

    Ginger (Zingiber officinale Roscoe, Zingiberaceae) has been widely used as a dietary spice, as well as in traditional oriental medicine. The rhizome of ginger contains pungent vanillyl ketones, including [6]-gingerol and [6]-paradol, and has been reported to possess a strong anti-inflammatory activity. These pungent substances have a vanilloid structure found in other chemopreventive phytochemicals, including curcumin. In our study, we found anti-tumor-promoting properties of [6]-gingerol and [6]-paradol. Thus, topical application of [6]-gingerol or [6]-paradol 30 min prior to 12-O-tetradecanoyl-phorbol-13-acetate (TPA) attenuated the skin papillomagenesis initiated by 7,12-dimethylbenz[a]anthracene in female ICR mice. These substances also significantly inhibited the tumor-promoter-stimulated inflammation, TNF-alpha production, and activation of epidermal ornithine decarboxylase in mice. In another study, [6]-gingerol and [6]-paradol suppressed the superoxide production stimulated by TPA in differentiated HL-60 cells. Taken together, these findings suggest that pungent vanilloids found in ginger possess potential chemopreventive activities. PMID:15281225

    Particles undergoing a stochastic motion within a disordered medium is a ubiquitous physical and biological phenomenon. Examples can be given from organelles as molecular machines of cells performing physical tasks in a populated cytoplasm to human mobility in patchy environment at larger scales. Our recent results showed that it is possible to use the disordered landscape generated by speckle light fields to perform advanced manipulation tasks at the microscale. Here, we use speckle light fields to study the anomalous diffusion of micron size silica particles (5 μm) in the presence of active microswimmers. The microswimmers we used in the experiments are motile bacteria, Escherichia coli (E.coli). They constitute an active background constantly agitating passive silica particles within complex optical potentials. The speckle fields are generated by mode mixing inside a multimode optical fiber where a small amount of incident laser power (maximum power = 12 μW/μm2) is needed to obtain an effective random landscape pattern for the purpose of optical manipulation. We experimentally show how complex potentials contribute to the anomalous diffusion of silica particles undergoing collisions with swimming bacteria. We observed an enhanced diffusion of particles interacting with the active bath of E.coli inside speckle light fields: this effect can be tuned and controlled by varying the intensity and the statistical properties of the speckle pattern. Potentially, these results could be of interest for many technological applications, such as the manipulation of microparticles inside optically disordered media of biological interests.

  14. A macromolecular crowding study of RNA folding and activity: polymer pore size matters! (Conference Presentation)

    Catalytic RNAs, like the group IIB intron ribozyme of S. cerevesiae, require a high magnesium(II) concentration to show folding and function in vitro [1]. In contrast, in vivo conditions are characterized by a highly crowded cellular environment and much lower ion concentration. Molecular crowding agents are a widespread tool to mimic cellular crowding [2]. However, particular physical/chemical properties explaining the crowders influence are mostly not understood. In this study, we gain new insights on how polymer properties like viscosity, pore size etc. influence the activity and folding of a large RNA. We combined bulk activity assays and single-molecule Förster Resonance Energy Transfer experiments, screening the PEG volume fraction (%) and molecular weight (MW). Our results revealed that upon the influence of crowding agents, a compaction of the underlying structure depends on the PEG % and the presence of different PEG MW and % unveiled an optimal pore size in terms of catalytic activity. In summary, an increasing density of the crowding environment shifts the RNA towards the most compact state, but the ribozyme is only active if the crowders network matches its size [4]. We interpret the most compact state as necessary, but not sufficient, to keep the ribozyme active.

    This study evaluated the effects of 2-amino-thiophene derivatives on the promastigote and amastigote forms of Leishmania (Leishmania) amazonensis and their possible mechanisms of action. Initially, we evaluated the antileishmanial activity of ten 2-amino-thiophene derivatives on promastigote and axenic amastigote forms of Leishmania amazonensis and their cytotoxicity against murine macrophages and human red blood cells. Three promising compounds were selected for studies of the cell death process using flow cytometry analysis and a DNA fragmentation assay. The effects of the compounds were assessed on intramacrophagic amastigotes, and the modulation of cytokine and NO production was investigated. All thiophene derivatives showed antileishmanial activity against promastigotes and axenic amastigotes with less toxicity for murine macrophages and human red blood cells. The best values were obtained for compounds containing a lateral indole ring. Docking studies suggested that these compounds played an important role in inhibiting trypanothione reductase (TryR) activity. The selected compounds SB-200, SB-44, and SB-83 induced apoptosis in promastigotes involving phosphatidylserine externalization and DNA fragmentation in a pattern similar to that observed for the positive control. Additionally, SB-200, SB-44, and SB-83 significantly reduced the infection index of macrophages by the parasites; for compounds SB-200 and SB-83 this reduction was associated with increased TNF-α, IL-12, and NO levels. This study demonstrated the effective and selective action of 2-amino-thiophene derivatives against L. amazonensis, resulting in apoptosis-like cell death and immunomodulation in vitro. The results suggest that they are promising compounds for the development of new leishmanicidal drugs.

    The Instrumental Neutron Activation Analysis (INAA) and Radiometric Laboratory's current system is described. This laboratory has been in continuous operation for the past thirty years. A review is provided about the laboratory's analytical participation in trace element geochemical studies of the earth's upper mantle, trace impurity studies of high purity materials, the provenance study of archaeological glass beads, trace multi-element analyses of standard reference materials, the preparation of synthetic analytical standards for Neutron Activation Analysis, and providing a training course in nuclear analytical techniques for environmental samples. The multi-element analysis by INAA consists of determining elements like the rare earths La, Ce, Nd, Sm Eu, Tb, Dy, Ho, Yb, Lu, and also As, Ba, Cl, Co, Cr, Cs, Dy, Fe, Hf, Hg, K, Mn, Na, Ta, Th, U. The projected future of the laboratory is explained in terms of its resources, expertise in high precision analysis of trace impurities for the material selection that is to be used in rare event physics experiments. For example, this 'surface' laboratory can be efficiently interfaced/integrated with a deep underground low background counting facility, especially in the initial stages.

  6. Present wind activity on Mars - Relation to large latitudinally zoned sediment deposits

    Thomas, P.

    1982-01-01

    The relation of present Martian winds to large latitudinally zoned sediment deposits has been investigated using global wind streak data and mapping of large sand and dust deposits. Dune sand deposits occur primarily in three latitude belts: north polar (74-85 degrees North), low latitude (5 degrees North-20 degrees South), and south polar (40-80 degrees South). Comparison with wind streak data shows the high-latitude dunes to be in areas of seasonally reversing winds. The present winds can form latitudinal dune belts from a variety of initial dune distributions, including uniform distribution and a polar source. The presence of dune sand within the polar layered deposits, the erosional state of the deposits, and the present surface wind flow away from the poles indicate that both polar dune concentrations have been derived from erosion of the layered deposits. The low-latitude dunes are topographically confined in canyons and craters; they are probably subject to long-term reversal of orientations with climate cycles.

    2015-01-01

    The basal ganglia play an important role in beat perception and patients with Parkinson's disease (PD) are impaired in perception of beat-based rhythms. Rhythmic cues are nonetheless beneficial in gait rehabilitation, raising the question how rhythm improves movement in PD. We addressed this question with magnetoencephalography recordings during a choice response task with rhythmic and non-rhythmic modes of stimulus presentation. Analyses focused on (i) entrainment of slow oscillations, (ii) the depth of beta power modulation, and (iii) whether a gain in modulation depth of beta power, due to rhythmicity, is of predictive or reactive nature. The results show weaker phase synchronisation of slow oscillations and a relative shift from predictive to reactive movement-related beta suppression in PD. Nonetheless, rhythmic stimulus presentation increased beta modulation depth to the same extent in patients and controls. Critically, this gain selectively increased the predictive and not reactive movement-related beta power suppression. Operation of a predictive mechanism, induced by rhythmic stimulation, was corroborated by a sensory gating effect in the sensorimotor cortex. The predictive mode of cue utilisation points to facilitation of basal ganglia-premotor interactions, contrasting with the popular view that rhythmic stimulation confers a special advantage in PD, based on recruitment of alternative pathways.

    Avocado fruit is a rich source of health-related lipophilic phytochemicals such as monounsaturated fatty acids, tocopherols, carotenes, acetogenins and sterols. However, limited information is available on the contribution of specific phytochemicals to the overall antioxidant capacity (AOC) of the fruit. Centrifugal partition chromatography was used as fractionation tool, guided by an in vitro chemical assay of oxygen radical absorbance capacity (ORAC). Subsequent experiments focused on isolation and characterization of the chemical nature of the main contributors to lipophilic AOC of avocado pulp. ORAC values obtained for acetogenins were contrasted with results from an isolated kidney mitochondria membrane lipid peroxidation bioassay. The present study established that lipophilic AOC of the pulp was significantly higher than its hydrophilic AOC. Our results confirmed the presence of acetogenins in the fractions with highest lipophilic AOC, and for the first time linked them as contributors to lipophilic-ORAC values. Further HPLC-PDA/MS-TOF analysis led to structural elucidation of two novel acetogenins, not previously reported as present in avocado pulp, along with five already known related-compounds. Antioxidant properties observed for avocado pulp acetogenins by the ORAC assay suggested that, in the presence of an emulsifying agent, acetogenins could serve as novel lipophilic antioxidants in a food matrix. Results from isolated mitochondria lipid peroxidation bioassay, indicated that L-ORAC values which may have relevance for food matrix applications, should not be interpreted to have a direct relevance in health-related claims, compounds need to be evaluated considering the complexity of biological systems.

At the same time, MITI published so called {open_quotes}New Earth 21{close_quotes} project which aims remedying the earth environment modified by human activities since industrial innovation began at about 200 years ago in coming 100 years. This plan proposed yearly step of research development of technology for mitigating CO{sub 2} emission. According to the MITI`s plan, 15 institutions belonging to AIST have carrying research for developing technology of reducing emission of CO{sub 2} and other greenhouse gases, with cooperation of other research organizations such as RITE (research Institute of Innovative Technology for Earth) and NEDO (New Energy and Industrial Technology Developing Organization). Time schedule of the research development by The New Earth 21 project is summarized in Table 2. Now, in Japan, many national institutions and universities, research works relating reduction and mitigation of GHG are carried out according to this guideline.

    This paper was aimed at studying sustainable solutions for the treatment of water polluted by octylphenols and nonylphenols that are xenoextrogen compounds affecting human health and dangerous for the aquatic environment. We studied the removal of 4-octylphenol and 4-n-nonylphenol with concentrations of the order of 5-10 mg/l on a laboratory scale. A mixing time of 10 min with 0.1 g/l of magnetic-activated carbons (MACs) was enough to obtain 95 +/- 5% adsorption of both 4-octylphenol and 4-n-nonylphenol. The adsorption of the surfactants IGEPAL CO-630 and TRITON X-100, which are precursors of branched 4-nonylphenol and the carcinogenic 4-tert-octylphenol, respectively, was also studied using the same technique. For concentrations between 2 and 10mg/l of these alkylphenols ethoxylated, after 10min mixing with 0.5 g/l of MACs, a 95 +/- 5% adsorption was obtained. A 97 +/- 1% removal of MACs was achieved after 10min of continuous-flow magnetic filtration (14.5 l/min). The filter used was made of SUS440C magnetic steel spheres. Srm-Co permanent magnets provided a uniform flux density field of about 500 mT. PMID:24645486

    Electrical activity of the human brain has been monitored using socalled charge mode (Laplacian estimates) during the exposure with short video film excerpts of 7 min duration. Eighty subjects (50% male and female) watched 5 different film excerpts (disney, animal, comedy, erotic and sex scenes) separated by 3 min pause. Comparison to a reference period of 7 min without video exposure revealed strong decreases in alpha and beta power starting from the electrode position T6 (right temporal) and spread to other brain areas with stronger attentional stimuli e.g. during the erotic and sex films. Highly statistically significant differences were observed between male and female in temporal areas, who in general developed stronger decreases than males. Females on the other hand produced significant increases in fronto-central delta and theta power which could be interpreted as expression of higher appreciation, whereas the decreases in alpha power in general are understood as signs of higher attention. The data are further proof that recording the computer aided quantitative EEG is a very fruitful and promising approach in psychophysiology. PMID:12844473

    The Mars Global Surveyor Mars Orbiter Camera has acquired data that establish the present-day impact cratering rate and document new deposits formed by downslope movement of material in mid-latitude gullies on Mars. Twenty impacts created craters 2 to 150 meters in diameter within an area of 21.5 x 10(6) square kilometers between May 1999 and March 2006. The values predicted by models that scale the lunar cratering rate to Mars are close to the observed rate, implying that surfaces devoid of craters are truly young and that as yet unrecognized processes of denudation must be operating. The new gully deposits, formed since August 1999, are light toned and exhibit attributes expected from emplacement aided by a fluid with the properties of liquid water: relatively long, extended, digitate distal and marginal branches, diversion around obstacles, and low relief. The observations suggest that liquid water flowed on the surface of Mars during the past decade.

    Avocado fruit is a rich source of health-related lipophilic phytochemicals such as monounsaturated fatty acids, tocopherols, carotenes, acetogenins and sterols. However, limited information is available on the contribution of specific phytochemicals to the overall antioxidant capacity (AOC) of the fruit. Centrifugal partition chromatography was used as fractionation tool, guided by an in vitro chemical assay of oxygen radical absorbance capacity (ORAC). Subsequent experiments focused on isolation and characterization of the chemical nature of the main contributors to lipophilic AOC of avocado pulp. ORAC values obtained for acetogenins were contrasted with results from an isolated kidney mitochondria membrane lipid peroxidation bioassay. The present study established that lipophilic AOC of the pulp was significantly higher than its hydrophilic AOC. Our results confirmed the presence of acetogenins in the fractions with highest lipophilic AOC, and for the first time linked them as contributors to lipophilic-ORAC values. Further HPLC-PDA/MS-TOF analysis led to structural elucidation of two novel acetogenins, not previously reported as present in avocado pulp, along with five already known related-compounds. Antioxidant properties observed for avocado pulp acetogenins by the ORAC assay suggested that, in the presence of an emulsifying agent, acetogenins could serve as novel lipophilic antioxidants in a food matrix. Results from isolated mitochondria lipid peroxidation bioassay, indicated that L-ORAC values which may have relevance for food matrix applications, should not be interpreted to have a direct relevance in health-related claims, compounds need to be evaluated considering the complexity of biological systems.

    AIM To investigate the incidence and general characteristics of sports-related eye injuries in patients visiting the Emergency Department. METHODS A cross-sectional, multi-center, observational study. Patients with an injured eye who visited the Emergency Department at one of nine hospitals in Korea were enrolled. All data were prospectively collected between March and September 2010 using a questionnaire. Eye injuries that occurred during risky sports were examined by gender and age. Additionally, the rate of open globe injuries that occurred with and without protective eyewear was examined for each activity. Continuous variables were compared using Student's t-test and categorical variables were compared using Chi-square test. RESULTS A total of 446 patients had sports-related eye injuries. Teenagers (10-19 years old) and young adults (20-29 years old) had the most eye injuries. Eye injuries accounted for 0.2% of Emergency Department patients. Baseball was the most common cause of sports-related eye injuries, followed by soccer and hiking. Protective gear was worn by 9.4% of all patients. Patients that were 30-39 years of age had the highest rate of protective gear use, followed by patients that were 40-49 years of age. The proportion of sports-related eye injuries that were open-globe injuries was highest for soccer and hiking. CONCLUSION Although injuries were most common in patients below the age of 10 years, these patients had the lowest rate of protective eyewear use. Injuries in adults over 40 years of age most commonly occurred during hiking, but the rate of protective eyewear use was low. Young athletes should be educated on and provided with protective eyewear and policies protective gear use should be established. For older adults, eye protection should be encouraged, especially during hiking. PMID:27803871

    Background: Most college students do not adequately participate in enough physical activity (PA) to attain health benefits. A theory-based approach is critical in developing effective interventions to promote PA. The purpose of this study was to examine the utility of the newly proposed multi-theory model (MTM) of health behavior change in predicting initiation and sustenance of PA among college students. Methods: Using a cross-sectional design, a valid and reliable survey was administered in October 2015 electronically to students enrolled at a large Southern US University. The internal consistency Cronbach alphas of the subscales were acceptable (0.65-0.92). Only those who did not engage in more than 150 minutes of moderate to vigorous intensity aerobic PA during the past week were included in this study. Results: Of the 495 respondents, 190 met the inclusion criteria of which 141 completed the survey. The majority of participants were females (72.3%) and Caucasians (70.9%). Findings of the confirmatory factor analysis (CFA) confirmed construct validity of subscales (initiation model: χ2 = 253.92 [df = 143], P < 0.001, CFI = 0.91, RMSEA = 0.07, SRMR = 0.07; sustenance model: χ2= 19.40 [df = 22], P < 0.001, CFI = 1.00, RMSEA = 0.00, SRMR = 0.03). Multivariate regression analysis showed that 26% of the variance in the PA initiation was explained by advantages outweighing disadvantages, behavioral confidence, work status, and changes in physical environment. Additionally, 29.7% of the variance in PA sustenance was explained by emotional transformation, practice for change, and changes in social environment. Conclusion: Based on this study’s findings, MTM appears to be a robust theoretical framework for predicting PA behavior change. Future research directions and development of suitable intervention strategies are discussed. PMID:27386419

  9. Interleukin-2 is Present in Human Blood Vessels and Released in Biologically Active Form by Heparanase

    Miller, John D.; Clabaugh, Suzanne E.; Smith, Deandra R.; Stevens, R. B.; Wrenshall, Lucile E.

    2011-01-01

    Interleukin-2 is a multifaceted cytokine with both immunostimulatory and immunosuppressive properties. Our laboratory recently demonstrated that the availability of IL-2 is regulated, in part, by association with perlecan, a heparan sulfate proteoglycan. Given the abundance of perlecan in blood vessels, we asked whether IL-2 is present in vessel walls. Our results indicate that IL-2 is associated with endothelial and smooth muscle cells within the human arterial wall. This IL-2 is released by heparanase, and promotes the proliferation of an IL-2 dependent cell line. Given the presence of IL-2 in human arteries, we asked whether the large vessels of IL-2 deficient mice were normal. The aortas of IL-2 deficient mice exhibited a loss of smooth muscle cells, suggesting that IL-2 may contribute to their survival. In their entirety, these results suggest a here-to-fore unrecognized role of IL-2 in vascular biology, and have significant implications for both the immune and cardiovascular systems. PMID:21606942

    PubMed

    Lyons, Claire; Kaufman, Annette R; Rima, Brandi

    2015-09-01

    This study explored the relationship between implicit theories of the body (ITB) and self-reported physical activity. ITB are beliefs about the malleability of the body. Individuals may hold entity ITB (that body appearance is fixed) or incremental ITB (that body appearance can be changed). Female undergraduate students (N = 313) completed an online survey assessing ITB, physical activity, and discrepancy between actual and ideal body weight. Participants endorsing incremental ITB reported more physical activity. A significant ITB by weight discrepancy interaction emerged. Developing interventions targeting implicit theories of the body may be one way to increase physical activity. PMID:24271689

  17. A specific DNA-binding protein activated by ionizing radiation in normal cells and constitutively present in ataxia telangiectasia cells

    Teale, B.; Lavin, M.F.

    1994-04-01

    Exposure of mammalian cells to ionizing radiation gives rise to a complex series of changes. This response is characterized by the induction of a variety of genes and the activation of pre-existing proteins. We describe here activation of a specific DNA-binding protein by ionizing radiation. The response was dose-dependent and specific for ionizing radiation. The binding factor appears to be normally present in the cytoplasma and responds to radiation by translocation to the nucleus, or is activated within the nucleus by an unknown mechanism. The radiation-induced activation of this protein appears to be mediated through a protein kinase C-associated pathway. A DNA-binding factor recognizing the same binding motif was found to be abnormally distributed in cells from patients with the human genetic disease, ataxiatelangiectasia. The protein was constitutively present in the nucleus and the cytoplasm of ataxia telangiectasia cells and did not respond to radiation. 27 refs., 5 figs.

    2007-02-01

    Assessment of cigarette smoking, alcohol consumption, physical activity, and diet in the Asian American and Pacific Islander (AAPI) community has been neglected. A questionnaire was used to investigate these health risk behaviors in 466 students at an urban community college and results for the 138 AAPI study participants were compared to the 328 non-Asians. Results for AAPI study participants showed that twenty percent (20.3%) were current cigarette smokers and 7.7% smoked eleven or more cigarettes per day. Ten percent (10.7%) reported binge drinking on one to two days per month and 17.3% reported binge drinking on three or more days per month. With regard to physical activity, 28.8% participated in stretching, 23.6% in strength and toning, 29.4% in moderate exercise, and 25.4% in vigorous exercise. Results indicated that on the day preceding the survey, only 11.9% consumed five or more servings of fruits and vegetables, 88.4% ate no more than two servings of high-fat foods, and 37.6% consumed tofu, soymilk, or other soy food. AAPI study participants were more likely to frequently binge drink (p < .05), less likely to participate in strength and toning exercises (p < .05), and more likely to consume soy foods daily (p < .01) than non-Asian study participants. Recommendations are presented for health promotion program planning. PMID:17269314

    Soon after Harlow Shapley became director of HCO in 1921, he established himself as a scientist who would speak out and take action on national and international issues. Recognizing the importance of international cooperation in astronomy, he frequently traveled abroad and in turn invited foreign scientists to visit and work at HCO. By the mid-1930s, Shapley was actively rescuing refugee scientists in war-torn Europe and placing them in American universities. Both Harvard and the FBI took note of his activities. Shapley feared intervention of any kind from either academia or the government. Desperate for funding, however, he finally went to Washington and lobbied Congress to set up the NSF. Through 1945, when Truman succeeded Roosevelt, Shapley pursued his political activities freely. That year he travelled to Moscow to represent Harvard at the 220th anniversary celebration of the Academy of Sciences. In Moscow he advocated international cooperation between Soviet and American scientists. Consequently, Shapley was subpoenaed for interrogation in 1946 by John Rankin, who served during the Truman administration as a one-man committee to investigate un-American activities. The ordeal infuriated Shapley. Headlines about it infuriated some Harvard alumni who urged the university to fire him. Although Shapley was nearing retirement, President Conant stood by his right to keep his job. By 1950, when Senator Joseph McCarthy was compiling a list of Communist sympathizers in the State Department, the FBI had a dossier on Shapley. McCarthy subpoenaed Shapley, but could not intimidate him. The Senator continued the witch hunt with Shapley's associates. First he harassed Martha Betz Shapley, then Donald Menzel. Both cleared themselves. Other associates, such as Bart Bok, were spared. Ultimately, the interrogation worked in Menzel's favor. It disassociated him from Shapley's ideology and political activities. When the Harvard Corporation sought the next director of HCO, Menzel

    The purpose of this study was to compare the differences in metabolic and energy cost (MEC) of college students while seated, standing, and during a sitting/stepping protocol. Participants were assessed via indirect calorimetry for 20 min in each of the following conditions: 1) seated in a standard office chair, 2) standing in place, and 3) a sitting/stepping protocol in which participants performed 1 min of stepping in place at 90 bpm, sat for 9 min, then repeated the stepping and sitting sequence once more. Participants completed each of the 3 trials in the aforementioned order, preceded with a 3 min acclimation period in each condition. A significant difference in MEC was observed between the 3 conditions, p < 0.001. Pairwise comparisons indicated that the sitting/stepping protocol resulted in significantly greater MEC than the seated and standing conditions (p < 0.001). Additionally, the standing protocol resulted in significantly greater MEC than the seated protocol (p < 0.001). The significant differences and large effect sizes between conditions indicate that interspersing sedentary bouts with brief activity can substantially increase MEC. Broader application of these findings may provide health promotion professionals with novel strategies to reduce sedentary behavior and improve health. PMID:27182423

    The prevalence of pathological gambling among college students is increasing. Few studies have directly examined the relation between reward processing and gambling severity while concurrently examining the effects of co-occurring negative affect in this at risk population. This study used Structural Equation Modeling (SEM) techniques to analyze results from an online survey of 352 female and 96 male students age 18-25. Participants completed measures of past year gambling behavior and severity of gambling problems using the Canadian Problem Gambling Index and the Problem Gambling Severity Index. Negative affect and reward processing were measured by the 21-item version of the Depression, Anxiety, and Stress Scales and the Behavioral Inhibition System and Behavioral Activation System (BIS/BAS) scales, respectively. Thirty-five percent of participants reported gambling in the previous 12 months, and 11% had gambling severity scores indicative of "moderate-risk" or "problem gambling." Gambling severity was associated with negative affect. Negative affect, in turn, was correlated with the unitary BIS scale and inversely associated with the BAS reward responsiveness scale. Reward responsiveness was also inversely associated with gambling severity. In the SEM models, the association between reward responsiveness and gambling severity was mediated by negative affect among males but not among females. Potential explanations for these findings and their implications for addressing problem gambling are discussed.

    Chondroblastomas are rare tumors that characteristically arise from the epiphyseal cartilage of long bones of the immature skeleton. Intracranial involvement is uncommon, though the squamous portion of the temporal bone is preferentially affected due to its cartilaginous origin. Patients with temporal bone chondroblastomas classically present with otologic symptoms, while primary neurological complaints are rare. In this report, we describe a 33 year-old man with a chondroblastoma of the temporal bone and an associated aneurysmal bone cyst constituting a large intracranial mass lesion who presented with new-onset seizure activity. We review issues relevant to the pathology and treatment of these lesions.

    Indirect restorations in contact with free gingival margins or principally within the gingival sulcus, where the presence of organic acids produced by oral biofilm is higher, may present faster degradation of the resin-based cement pellicle. Objectives: To investigate the degradation of four resin-based cements: Rely X ARC (R), Variolink II (V), enforce (E) and All Cem (A), after immersion in distilled water (DW), lactic acid (LA) and artificial saliva (AS) and to analyze the influence of the activation mode on this response. Material and Methods: Two activation modes were evaluated: chemical (Ch) and dual (D). In the dual activation, a two-millimeter thick ceramic disk (IPS empress System) was interposed between the specimen and light-curing unit tip. Specimens were desiccated, immersed in distilled water, artificial saliva and lactic acid 0.1 M at 37ºC for 180 days, weighed daily for the first 7 days, and after 14, 21, 28, 90 and 180 days and were desiccated again. Sorption and solubility (µg/mm3) were calculated based on ISO 4049. The data were submitted to multifactor analysis of variance (MANOVA) and Tukey's HSD test for media comparisons (α=0.05). Results: Sorption was higher after immersion in LA (p<0.05) and increased significantly with time (p<0.05). Sorption was influenced by the activation mode: Ch>D (p<0.05). The lowest solubility was presented by R (p<0.05). Conclusions: Lactic acid increased the degradation of resin-based cements. Moreover, the physical component of activation, i.e., light-activation, contributed to a low degradation of resin-based cements. PMID:23857651

    The purpose of this quasi-experimental study was to determine the effects on community college student physics conceptual achievement and attitudes about learning physics due to the use of inquiry-based laboratory activities versus cookbook laboratory activities. An analysis of covariance (ANCOVA) was performed to test for differences in mean post-test Force Concept Inventory (FCI) score for two different types of physics lab instruction (IL versus CBL). Results of the ANCOVA, F (1, 35) = 0.761, p < 0.389, supported the null hypothesis that no significant difference was found in the post-test FCI scores of the two groups. An ANCOVA was performed to test for differences in mean post-test Mechanics Baseline Test (MBT) score for two different types of physics lab instruction (IL versus CBL)., however, the covariate and the dependent variable were shown to not be linearly related. Therefore, a one-way analysis of variance (ANOVA) was used to compare MBT scores. The results of the ANOVA, F (1, 36) = 0.066, p < 0.798, supported the null hypothesis that there was no significant difference in MBT scores of the two groups. A step-wise multiple linear regression was used to analyze the relationships between the FCI post-test score and the type of instruction, FCI pre-test score, and American College Test (ACT) science reasoning sub-scores. The FCI pre-test score and ACT science score were shown to be the best predictors of FCI post-test score. Another step-wise multiple linear regression was used to analyze the relationships between the MBT post-test score and type of instruction, MBT pre-test score, and ACT science reasoning sub-scores. The ACT Science sub-scores were determined to be the best predictor of MBT post-test score. An independent t-test was used to compare the mean lecture test grades for the lab groups taught using inquiry and cookbook methods. The mean lecture test scores of the inquiry-based lab group (M = 81.39, S.D. = 8.15) were found to be significantly

    Interactions between poly-dispersed acid functionalized single walled carbon nanotubes (AF-SWCNTs) and primary lung epithelial (PLE) cells were studied. Peritoneal macrophages (PMs, known phagocytic cells) were used as positive controls in this study. Recovery of live cells from cultures of PLE cells and PMs was significantly reduced in the presence of AF-SWCNTs, in a time and dose dependent manner. Both PLE cells as well as PMs could take up fluorescence tagged AF-SWCNTs in a time dependent manner and this uptake was significantly blocked by cytochalasin D, an agent that blocks the activity of acto-myosin fibers and therefore the phagocytic activity of cells. Confocal microscopic studies confirmed that AF-SWCNTs were internalized by both PLE cells and PMs. Intra-trachially instilled AF-SWCNTs could also be taken up by lung epithelial cells as well as alveolar macrophages. Freshly isolated PLE cells had significant cell division activity and cell cycling studies indicated that treatment with AF-SWCNTs resulted in a marked reduction in S-phase of the cell cycle. In a previously standardized system to study BCG antigen presentation by PLE cells and PMs to sensitized T helper cells, AF-SWCNTs could significantly lower the antigen presentation ability of both cell types. These results show that mouse primary lung epithelial cells can efficiently internalize AF-SWCNTs and the uptake of nanotubes interfered with biological functions of PLE cells including their ability to present BCG antigens to sensitized T helper cells.

    l-Phenylalanine serves as a building block for the biosynthesis of proteins, but also as a precursor for a wide range of plant-derived compounds essential for plants and animals. Plants can synthesize Phe within the plastids using arogenate as a precursor; however, an alternative pathway using phenylpyruvate as an intermediate, described for most microorganisms, has recently been proposed. The functionality of this pathway requires the existence of enzymes with prephenate dehydratase (PDT) activity (EC 4.2.1.51) in plants. Using phylogenetic studies, functional complementation assays in yeast and biochemical analysis, we have identified the enzymes displaying PDT activity in Pinus pinaster. Through sequence alignment comparisons and site-directed mutagenesis we have identified a 22-amino acid region conferring PDT activity (PAC domain) and a single Ala314 residue critical to trigger this activity. Our results demonstrate that all plant clades include PAC domain-containing ADTs, suggesting that the PDT activity, and thus the ability to synthesize Phe using phenylpyruvate as an intermediate, has been preserved throughout the evolution of plants. Moreover, this pathway together with the arogenate pathway gives plants a broad and versatile capacity to synthesize Phe and its derived compounds. PAC domain-containing enzymes are also present in green and red algae, and glaucophytes, the three emerging clades following the primary endosymbiont event resulting in the acquisition of plastids in eukaryotes. The evolutionary prokaryotic origin of this domain is discussed. PMID:27125254

    "Lane Late" sweet orange grafted on six different citrus rootstocks and grown in the Guadalquivir valley (Seville, Spain) were picked at different ripening stages in two consecutive seasons to characterize their antioxidant activity (free radicals scavenging activity, reducing power and lipid peroxidation inhibition) and quantify their main antioxidant compounds (vitamin E and vitamin C). Linear discriminant analysis and 2-way ANOVA were applied to compare the effects induced by citrus rootstock and ripening stage. The results showed that differences in antioxidant activity and related compounds are mainly dependent on the citrus rootstock, despite ripening stage had also some particular effects. Changes observed in 2012 showed less marked differences among the citrus rootstock. Nevertheless, Cleopatra rootstock showed the highest antioxidant activity in both years, indicating that an increase in its cultivation might be a good solution to sweet orange farmers. Concerning the ripening stage, samples collected in January presented higher vitamin contents, while those collected in April showed higher antioxidant activity. This result allows deciding the harvesting period according to the desired effect.

  20. Impact of the Yakutat indentor corner on present-day tectonics and fault activity in SE Alaska - SW Yukon

    NASA Astrophysics Data System (ADS)

    Mazzotti, S.; Marechal, A.; Ritz, J. F.; Ferry, M. A.

    2015-12-01

    We present an active tectonic model of the SE Alaska - SW Yukon region based principally on the integration of recent GPS velocity data and new fault-slip rates derived from geomorphology. In this region, the Yakutat collision results in complex tectonics with patterns of strain localization and strain partitioning that strongly vary across the various mountain ranges and active faults. We propose that deformation and fault activity in the St. Elias and Chugach Mountains are primarily controlled by the eastern syntaxis of the Yakutat collision, which produces a semi-radial tectonic pattern: Velocities, principal horizontal shortening rates, and maximum horizontal stress orientations rotate by 60 - 80 ° around the syntaxis, from roughly parallel to the relative Pacific - North America motion at the front of the collision to roughly orthogonal southeast of the syntaxis. The interaction between this strain pattern and major inherited tectonic structures inland of the collision zone (i.e., Denali and Duke River Faults) results in various reactivation modes of these structures. Specifically, the Denali Fault shows a very pronounced lateral variations of activity from ~12 mm/a of dextral slip rate in its central section to ~1 mm/a of mostly shortening slip rate along its southern section. This marked change of activity is associated with a possible relay system where the Duke River and Totschunda Faults accommodate a major part (8 - 12 mm/a) of the inland strain transfer directly in front of the syntaxis. This new tectonic model retains some questions, in particular regarding the mechanisms of deformation and strain transfer (1) from the syntaxis to the Duke River - Totschunda system and (2) at the junction between Totschunda and Denali Faults. Numerical models of present-day deformation may help address these issues and provide information about relative strength of the various crustal and inherited fault elements of this system.

    Wiskott–Aldrich syndrome (WAS) is caused by loss-of-function mutations in the WASp gene. Decreased cellular responses in WASp-deficient cells have been interpreted to mean that WASp directly regulates these responses in WASp-sufficient cells. Here, we identify an exception to this concept and show that WASp-deficient dendritic cells have increased activation of Rac2 that support cross-presentation to CD8+ T cells. Using two different skin pathology models, WASp-deficient mice show an accumulation of dendritic cells in the skin and increased expansion of IFNγ-producing CD8+ T cells in the draining lymph node and spleen. Specific deletion of WASp in dendritic cells leads to marked expansion of CD8+ T cells at the expense of CD4+ T cells. WASp-deficient dendritic cells induce increased cross-presentation to CD8+ T cells by activating Rac2 that maintains a near neutral pH of phagosomes. Our data reveals an intricate balance between activation of WASp and Rac2 signalling pathways in dendritic cells. PMID:27425374

    The Fulani ethnic group from West Africa is relatively better protected against Plasmodium falciparum malaria as compared to other sympatric ethnic groups, such as the Dogon. However, the mechanisms behind this lower susceptibility to malaria are largely unknown, particularly those concerning innate immunity. Antigen-presenting cells (APCs), and in particular dendritic cells (DCs) are important components of the innate and adaptive immune systems. Therefore, in this study we investigated whether APCs obtained from Fulani and Dogon children exhibited differences in terms of activation status and toll-like receptor (TLR) responses during malaria infection. Lower frequency and increased activation was observed in circulating plasmacytoid DCs and BDCA-3+ myeloid DCs of infected Fulani as compared to their uninfected counterparts. Conversely, a higher frequency and reduced activation was observed in the same DC subsets obtained from peripheral blood of P. falciparum-infected Dogon children as compared to their uninfected peers. Moreover, infected individuals of both ethnic groups exhibited higher percentages of both classical and inflammatory monocytes that were less activated as compared to their non-infected counterparts. In line with APC impairment during malaria infection, TLR4, TLR7 and TLR9 responses were strongly inhibited by P. falciparum infection in Dogon children, while no such TLR inhibition was observed in the Fulani children. Strikingly, the TLR-induced IFN-γ release was completely abolished in the Dogon undergoing infection while no difference was seen within infected and non-infected Fulani. Thus, P. falciparum infection is associated with altered activation status of important APC subsets and strongly inhibited TLR responses in peripheral blood of Dogon children. In contrast, P. falciparum induces DC activation and does not affect the innate response to specific TLR ligands in Fulani children. These findings suggest that DCs and TLR signalling may be

    Arachnida is the largest class among the arthropods, constituting over 60,000 described species (spiders, mites, ticks, scorpions, palpigrades, pseudoscorpions, solpugids and harvestmen). Many accidents are caused by arachnids, especially spiders and scorpions, while some diseases can be transmitted by mites and ticks. These animals are widely dispersed in urban centers due to the large availability of shelter and food, increasing the incidence of accidents. Several protein and non-protein compounds present in the venom and saliva of these animals are responsible for symptoms observed in envenoming, exhibiting neurotoxic, dermonecrotic and hemorrhagic activities. The phylogenomic analysis from the complementary DNA of single-copy nuclear protein-coding genes shows that these animals share some common protein families known as neurotoxins, defensins, hyaluronidase, antimicrobial peptides, phospholipases and proteinases. This indicates that the venoms from these animals may present components with functional and structural similarities. Therefore, we described in this review the main components present in spider and scorpion venom as well as in tick saliva, since they have similar components. These three arachnids are responsible for many accidents of medical relevance in Brazil. Additionally, this study shows potential biotechnological applications of some components with important biological activities, which may motivate the conducting of further research studies on their action mechanisms.

    Although being a normal part of the skin flora, yeasts of the genus Malassezia are associated with several common dermatologic conditions including pityriasis versicolour, seborrhoeic dermatitis (SD), folliculitis, atopic eczema/dermatitis (AE/AD) and dandruff. While Malassezia spp. are aetiological agents of pityriasis versicolour, a causal role of Malassezia spp. in AE/AD and SD remains to be established. Previous reports have shown that fungi such as Candida albicans and Aspergillus fumigatus are able to efficiently activate the NLRP3 inflammasome leading to robust secretion of the pro-inflammatory cytokine IL-1β. To date, innate immune responses to Malassezia spp. are not well characterized. Here, we show that different Malassezia species could induce NLRP3 inflammasome activation and subsequent IL-1β secretion in human antigen-presenting cells. In contrast, keratinocytes were not able to secrete IL-1β when exposed to Malassezia spp. Moreover, we demonstrate that IL-1β secretion in antigen-presenting cells was dependent on Syk-kinase signalling. Our results identify Malassezia spp. as potential strong inducers of pro-inflammatory responses when taken up by antigen-presenting cells and identify C-type lectin receptors and the NLRP3 inflammasome as crucial actors in this process.

    Background. The presence of ulcerative colitis (UC) with no bowel symptoms, as fever of unknown origin (FUO), is uncommon. Objective. To describe the case of an 80-year-old woman who presented with fever, with a history of UC under treatment with mesalazine. Case Presentation. She was admitted due to fever lasting for 12 days with no associated symptoms. Seven years earlier, she was diagnosed with UC. After an extended workup for FUO that failed to reach the diagnosis, she underwent a gallium-67 scintigraphy. This revealed a persistent diffuse concentration of gallium-67 in the ascending colon at 24-hour imaging that remained stable at 48- and 72-hour imaging without any topographic change after the use of laxatives. Considering the results and in the absence of another diagnosis, the patient was treated with 30 mg prednisone daily and mesalazine, as treatment of active UC. Subsequently, the patient's condition improved markedly and the fever retreated. One month later, she was reevaluated with a gallium-67 scintigraphy with total absence of gallium-67 concentration in the ascending colon. Conclusion. UC activity must be included in the differential diagnosis of FUO in patients with longstanding disease, since fever may present alone, with no other manifestations. PMID:27504121

    Objetivo: El objetivo de este trabajo fue analizar la prevalencia de barreras y su asociación con la práctica de AF en universitarios de Colombia. Métodos: Estudio descriptivo de corte transversal, en 5.663 sujetos (3.348 hombres), de tres ciudades de Colombia. Las razones que podrían impedir realizar AF, se evaluaron con el cuestionario de “Percepción de barreras para la práctica de la actividad física” (en inglés, Barriers to Being Active Quiz-21 ítems). Un análisis de regresión logística para cada barrera ajustado por las variables de confusión (sexo, edad e IMC) fue usado para verificar la asociación. Resultados: En la población general, el “miedo a lastimarse” (89,5%) y la “falta de habilidades” (82,1%) eran, en este orden, las razones más frecuentes como barreras auto-percibidas de la práctica de AF. El grupo de mujeres mostró una asociación protectora en relación con las barreras “falta de tiempo” (OR = 0,53 IC95% 0,47-0,60), “influencia social” (OR = 0,67 IC95% 0,60-0,75), “falta de energía” (OR = 0,54 IC95% 0,49-0,61), “falta de voluntad” (OR = 0,57 IC95% 0,51-0,64), “falta de habilidades” (OR = 0,76 IC95% 0,66-0,87) y “falta de recursos” (OR = 0,79 IC95% 0,71-0,89). Esta observación también aparece en el grupo de edades comprendidas entre los 20 y 23 años en la barrera “influencia social” (OR = 0,83 IC95% 0,74-0,94), y en los mayores a 23 años (OR = 0,86 IC95% 0,74-0,99) en la barrera “falta de energía”. Conclusión: Se encontró una importante prevalencia en la percepción de las barreras para cesar la práctica de AF. Estos resultados pueden servir de referencia para las acciones específicas para promover la AF y la salud en universitarios de Colombia.

    This study examined (1) the relationships between self-presentation processes (i.e., impression motivation and impression construction) and moderate-to-vigorous physical activity (MVPA) among breast cancer survivors, and (2) whether social cognitive constructs (i.e., self-presentational efficacy expectancy [SPEE]; self-presentational outcome expectancy [SPOE]; self-presentational outcome value [SPOV]) moderate these relationships. Breast cancer survivors (N = 169; Mage = 55.06, SD = 10.67 years) completed self-report measures. Hierarchical regression analysis, controlling for age and body mass index, indicated that impression motivation was a significant correlate of MVPA (β = .25). Furthermore, SPEE (β = .21) and SPOV (β = .27) were moderators of this relationship. The final models accounted for 12-24% of the variance in MVPA. The findings of this study suggest that self-presentation processes (i.e., impression motivation) may indeed relate to breast cancer survivors' MVPA. In addition, social cognitive constructs (i.e., SPEE, SPOV) moderated the relationship between impression motivation and MVPA. It may be effective to target impression motivation, SPEE, and SPOV in interventions aimed at increasing MVPA among breast cancer survivors.

    Background African American women report low levels of physical activity (PA) and are disproportionately burdened by related chronic diseases. This pilot study tested a 6-month theory-based (Social Cognitive Theory, SCT) culturally-relevant website intervention to promote PA among African American female college students. Materials and Methods A single group pre-post test design (n=34) was used. PA and associated SCT constructs (outcome expectations, enjoyment, self-regulation, social support) were assessed at baseline, 3 months and 6 months. Results The sample was comprised of mostly obese (M BMI= 35.4, SD=6.82) young adults (M age= 21.21 years, SD=2.31). Fifty percent of the sample completed all assessments. Intent-to-treat analyses showed that participants reported a significant median improvement in moderate-to-vigorous physical activity from 82.5 minutes/week (M=81.76, SD=76.23) at baseline to 115.0 minutes/week (M=122.44, SD=97.93) at 3 months (Wilcoxon z=2.39, p=.02). However these gains appear to have attenuated by 6 months (Median= 82.5 minutes/week, M=96.73, SD=84.20; Wilcoxon z=1.02, p=.31). Significant increases from baseline to 6 months were found in self-regulation for PA (p=.02) and social support for PA from friends (p=.02). Changes in the SCT variables were not significantly associated with changes in PA; however, this may have been due to small sample size. Conclusions Future studies with larger samples and more aggressive retention strategies (e.g., more frequent incentives, prompts for website use) are needed to further explore the applicability of web-based approaches to promote PA in this at-risk population.

    Metabolic dysfunction in hypoparathyroidism is an important cause of intracranial calcifications, which cause cognitive impairment depending on the calcified areas leading to difficulties in executing activities of daily living. We report a case of a 25-year-old man who presented with gradually decreasing organisational skills, memory problems and difficulty in carrying out daily activities. CT imaging of the brain showed extensive calcification in the basal ganglia and cerebral white matter. Comprehensive health-related quality of life and cognitive assessment revealed significant affliction in his activities of daily living along with impairment in recall memory, executive functions and verbal fluency. Owing to late diagnosis, chronicity of cognitive problems could not prevent him from discontinuing his college education. PMID:23709145

    semana es bajo y la mediana del número de horas en reposo por día fue de 12 horas, con un rango intercuartílico de 4 horas. Se encontró asociación estadísticamente significativa entre el exceso de peso determinado por porcentaje de grasa total corporal y el sedentarismo con un OR ajustado de 1.11 (IC 95% 1.01 - 1.23). Conclusiones: No se encontró asociación estadísticamente significativa con el IMC y la actividad física, sin embargo sí se encontró asociación con el porcentaje de grasa total corporal y el sedentarismo. Esto puede ser explicado porque en la mayoría de estudios epidemiológicos han usado el IMC como método de valoración de la composición corporal, sin embargo, éste no diferencia entre el peso asociado con músculo y el peso asociado con grasa, argumento que podría estar explicando lo hallado en el presente estudio.

    This chapter discusses the collaboration between a national college access program, the National College Advising Corps (NCAC), and its research and evaluation team at Stanford University. NCAC is currently active in almost four hundred high schools and through the placement of a recent college graduate to serve as a college adviser provides necessary information and support for students who may find it difficult to navigate the complex college admission process. The advisers also conduct outreach to underclassmen in an effort to improve the school-wide college-going culture. Analyses include examination of both quantitative and qualitative data from numerous sources and partners with every level of the organization from the national office to individual high schools. The authors discuss balancing the pursuit of evaluation goals with academic scholarship. In an effort to benefit other programs seeking to form successful data-driven interventions, the authors provide explicit examples of the partnership and present several examples of how the program has benefited from the data gathered by the evaluation team.

    The comfort of dairy cattle while standing has important implications for housing design. Research has examined how cattle respond to standing surfaces by presenting options under all 4 legs or under a single leg, but no work, to date, has compared presentation methods. This study examined behavior and muscle activity when cows stood on rough floors under all 4 legs or just 1 hind leg. Three treatments were tested: smooth concrete under all 4 legs (0-ROUGH), a rough surface under all 4 legs [2cm × 2cm × 4cm trapezoidal protrusions (4-ROUGH)], and a rough surface only under 1 hind leg, with other legs on smooth concrete (1-ROUGH). Twenty-four healthy Holstein cows stood on each surface for 1h/d in a repeated-measures design. Surface electromyograms (SEMG) were used to evaluate muscle fatigue and total activity. Muscle fatigue was measured using SEMG to evaluate (1) static contractions when cows were continuously weight bearing on each hind leg, before and after 1h of standing, and (2) dynamic contractions associated with steps during 1h of standing. Behavioral measures included steps per minute, time between each consecutive step, and the latency to lie down after testing. The number of legs affected by roughness influenced both behavioral and physiological responses to flooring. Cows on 1-ROUGH stepped twice as often with the rough-treated leg and one-half as much with the hind leg on smooth concrete compared with other surfaces. Similarly, on the 1-ROUGH surface, total muscle activity was reduced in the leg on the rough surface, and muscle activity was more sustained (3× higher) in the other hind leg, suggesting that cows avoid possible discomfort under 1 leg by using muscles in the other. In the 4-ROUGH treatment, time between steps was more variable than on the other 2 treatments (coefficient of variation, 4-ROUGH: 245; 1-ROUGH: 208; 0-ROUGH: 190±5.8%), likely because cows could not move away from this uneven flooring. Thus, the method of presentation of

    Cell surface CD47 interacts with its receptor, signal-regulatory-protein α (SIRPα) that is expressed predominantly on macrophages, to inhibit phagocytosis of normal, healthy cells. This “don’t eat me” signal is mediated through tyrosine phosphorylation of SIRPα at the cytoplasmic ITIM motifs and the recruitment of the phosphatase, SHP-1. We previously revealed a novel mechanism for the activation of the STAT3 pathway and the regulation of human APC maturation and function that is based on cell:cell interaction. In this study, we present evidence supporting the notion that CD47:SIRPα serves as a cell surface receptor: ligand pair involved in this contact-dependent STAT3 activation and regulation of APC maturation. We show that upon co-culturing APC with various primary and tumor cell lines STAT3 phosphorylation and IL-10 expression are induced, and such regulation could be suppressed by specific CD47 siRNAs and shRNAs. Significantly, >50% reduction in CD47 expression abolished the contact-dependent inhibition of T cell activation. Furthermore, co-immunoprecipitation experiments revealed a physical association between SIRPα and STAT3. Thus, we suggest that in addition to signaling through the ITIM-SHP-1 complex that transmit an anti-phagocytotic, CD47:SIRPα also triggers STAT3 signaling that is linked to an immature APC phenotype and peripheral tolerance under steady state and pathological conditions.

    Langerhans cells (LCs) are known as “sentinels” of the immune system that function as professional antigen-presenting cells (APCs) after migration to draining lymph node. LCs are proposed to have a role in tolerance and the resolution of cutaneous immune responses. The Programmed Death-1 (PD-1) receptor and its ligands, PD-L1 and PD-L2, are a co-inhibitory pathway that contributes to the negative regulation of T-lymphocyte activation and peripheral tolerance. Surprisingly, we found PD-1 to be expressed on immature LCs (iLCs) in situ. PD-1 engagement on iLCs reduced IL-6 and macrophage inflammatory protein (MIP)-1α cytokine production in response to TLR2 signals but had no effect on LC maturation. PD-L1 and PD-L2 were expressed at very low levels on iLCs. Maturation of LCs upon migration from epidermis led to loss of PD-l expression and gain of high expression of PD-L1 and PD-L2 as well as co-stimulatory molecules. Blockade of PD-L1 and/or PD-L2 on migratory LCs (mLCs) and DDCs enhanced T-cell activation, as has been reported for other APCs. Thus the PD-1 pathway is active in iLCs and inhibits iLC activities, but expression of receptor and ligands reverses upon maturation and PD-L1 and PD-L2 on mLC function to inhibit T-cell responses.
