    The glacier is most important the freshwater resources and indicator of the climate change. The researchers noted that during last decades the glacier is melting due to global warming. The study calculates a spatial distribution of protentional change of glacier coverage in the Ikh Turgen mountain of Western Mongolia, and it integrates long-term climate data and satellite datasets. Therefore, in this experiment has tried to estimation three-dimensional surface area of the glacier. For this purpose, Normalized difference snow index (NDSI) was applied to decision tree approach, using Landsat MSS, TM, ETM+ and LC8 imagery for 1975-2016, a surface and slope for digital elevation model, precipitation and air temperature historical data of meteorological station. The potential volume area significantly changed glacier cover of the Ikh Turgen Mountain, and the area affected by highly variable precipitation and air temperature regimes. Between 1972 and 2016, a potential area of glacier area has been decreased in Ikh Turgen mountain region.

    Full Text Available Ikh Nart Nature Reserve remains poorly studied for invertebrates, especially for vespid wasps. A total of 14 vespid species belonging to seven genera of the subfamily Eumeninae were recorded from diff erent habitats (rocky outcrops, springs, tall vegetation habitats, shrub-lands and short grass steppes in the nature reserve during three-year studies (2015-2017. These species represent 27 percent of the vespid fauna of the desert-steppe zone of Mongolia. We found the highest species richness in areas where water was available (near springs and wells, and the lowest richness in habitats with tall vegetation. Among the diff erent habitat types, vespid species composition was most similar (91% shared species between rocky outcrops and spring habitats. Six vespid species range from Kazakhstan to Mongolian, and one species is sub-endemic to Mongolia. Availability of water sources and nesting sites were possibly the main factors infl uencing the distribution of vespid wasps. It is necessary to conduct comprehensive research into the insect community of Ikh Nart Nature Reserve.

    Full Text Available Spatially-explicit wildlife habitat models are increasingly used to study optimal habitat for species of conservation focus. A ruggedness layer, that summarizes aspect and slope, provides a useful tool for analyses conducted in a Geographic Information System (GIS, such as developing a habitat suitability index model to measure species habitat use. Ruggedness layers prove especially useful in areas where topography represents a key habitat component. We created a ruggedness layer for the Ikh Nart Nature Reserve and surrounding areas in northern Dornogobi Aimag (province, Mongolia. Using a 90 m Shuttle Radar Topography Mission (SRTM digital elevation model (DEM and ArcGIS 10 spatial analyst, we created 9 categories for ruggedness. When combined with other thematic layers such as vegetation, the ruggedness layer becomes a powerful tool for analyzing habitat use by individual animals. The results of such analyses may inform decision makers in protected area planning and conservation of endangered species.

    of faulty candidates (t = Ω(n)). Previous OT-combiners required either ω(n) or poly(k) calls to the n candidates, where k is a security parameter, and produced only a single secure OT. We demonstrate the usefulness of the latter result by presenting several applications that are of independent interest......An OT-combiner implements a secure oblivious transfer (OT) protocol using oracle access to n OT-candidates of which at most t may be faulty. We introduce a new general approach for combining OTs by making a simple and modular use of protocols for secure computation. Specifically, we obtain an OT......, strengthen the security, and improve the efficiency of previous OT-combiners. In particular, we obtain the first constant-rate OT-combiners in which the number of secure OTs being produced is a constant fraction of the total number of calls to the OT-candidates, while still tolerating a constant fraction...

    2012-12-01

    Full Text Available We examined home range characteristics and habitat selection of Daurian hedgehogs in Ikh Nart Nature Reserve, Mongolia. Home ranges of hedgehogs varied from 113.15 ha to 2,171.97 ha, and were larger in early summer than late summer. Hedgehogs showed relative preference for rocky outcrops and low-density shrub habitats, and relative avoidance of high- density shrub areas. Habitat selection also changed between early and late summer, shifting to greater use of low-density shrub areas and decreased use of forb-dominated short grass. Our baseline data on home ranges and habitat selection expand understanding of hedgehog ecology and provide guidance for future management decisions in Ikh Nart Nature Reserve and elsewhere in Mongolia.

  7. Evaluating the Quality of Protected Areas for Species: A Case Study in Ikh Nart Nature Reserve, Mongolia

    2014-12-01

    Full Text Available Species’ distributions refl ect the quality of landscape conditions, and represent an important component of protected area management. However, distributions are diffi cult to estimate, and consequently, often determined through a combination of limited fi eld data and expert opinion, which may lead to biases. We demonstrate the use of occupancy models to map distributions and estimate landscape quality. We used occupancy models for two species, the red fox and toad-headed agama, to map their distributions in Ikh Nart Nature Reserve located in southeastern Mongolia. We then used occupancy probability as a measure of quality and tested whether differences existed in quality between three areas: 1 inside the reserve, 2 inside the reserve’s core protected area, and 3 outside the reserve, using 30 sample sites in each. Occupancy probability varied from 0.084 to 0.997 for red foxes and 0.022 to 0.949 for agamas in maps. Landscape quality was highest in the core area and lowest outside the reserve for red foxes, and highest outside the reserve and lowest in the core area for agamas. Our results provide visual depictions of distributions across the Ikh Nart landscape and a means of assessing the quality of the Ikh Nart protected area that may inform management activities.

  8. Factors Affecting Home Ranges of Red Foxes in Ikh Nart Nature Reserve, Mongolia

    Full Text Available Changes in red fox home range size in relation to environmental and intrinsic factors were studied using radio-telemetry during 2006–2008 in Ikh Nart Nature Reserve, southeastern Mongolia. We captured a total of 12 red foxes (8 females and 4 males and fi tted them with VHF radio-collars. Marked animals were tracked up to fi ve times a week to estimate home ranges. We also trapped small mammal and insects in different biotopes for 3 years to estimate relative abundance of prey. Our results showed that mean individual home range sizes varied widely and differed among years. There was variation in home ranges between adults versus juveniles, but no signifi cant difference was found between males versus females. In addition, mean home range size did not differ seasonally for pooled years. Variation in home ranges was best explained by a model that included covariates of year and age. We suggest that spatiotemporal changes in resource availability across years infl uenced home range dynamics of red foxes in our study.

    Full Text Available The lesser kestrel is recognized as “Least Concern” in the International Union for Conservation of Nature (IUCN Red List since 2011. So far, all available diet studies on the lesser kestrel were conducted in its European range or in partial African breeding and nonbreeding range. In particular, little is known about the feeding behavior of this small falcon in Asian ranges. Thus, this study can be considered as the first to examine the diet composition of the central Asian breeding populations of lesser kestrels. This study aims to provide some information about the diet composition of this species among Asian populations through biological and ecological investigations. Pellets (n = 762 dropped by lesser kestrel (Falco naumanni were collected during their breeding season from nine to 10 colony sites in Ikh Nart, between June and September of 2009 and 2010, and analyzed. A total of 1,484 prey items were identified in the pellets collected. After a measure of their weight (g and length and width (mm, we carefully examined each pellet and separated all prey remains using tweezers. Our results indicated that insects (including orthopterans and coleopterans were dominant in lesser kestrel’s diets. We found that the lesser kestrel’s diet mainly consisted of insects (69.7%, lizards (17.4%, small mammals (10%, small birds (2%, and other food (1%.

    2005-06-01

    Full Text Available Cinereous vultures ( Aegypius monachus are the largest raptors in Eurasia. Little is known about the species, especially in Mongolia. We studied the nesting ecology of cinereous vultures in Ikh Nartyn Chuluu Nature Reserve, Dornogobi Aimag. To assess reproductive success, we located active nests and periodically checked to determine if they remained active. We measured nest sizes and, periodically, nestling sizes and weights. We located 42 active cinereous vulture nests (27 on rocks and 15 on trees in 2003 and 19 nests (14 on rocks and 5 on trees in 2004. Mean volume of active nests was 3.92 ± 0.39 m 3 ( n = 36. Most nests failed prior to egg hatching, but after hatching nesting success rates increased dramatically. Following hatching, cinereous vulture chicks grew linearly until leveling off just prior to fledging. We generated growth curves for chicks that allowed us to determine the average size of chicks on specific dates. Improving the prospects for successful cinereous vulture conservation likely requires a better understanding of nesting ecology. As such, we plan to improve the quality of our data by monitoring nests more intensively to determine incubation and fledging lengths, as well as causes of nest failures.

  12. LATERAL SURVIVAL: AN OT ACCOUNT

    Directory of Open Access Journals (Sweden)

    Moira Yip

    2004-12-01

    Full Text Available When laterals are the targets of phonological processes, laterality may or may not survive. In a fixed feature geometry, [lateral] should be lost if its superordinate node is eliminated by either the spreading of a neighbouring node, or by coda neutralization. So if [lateral] is under Coronal (Blevins 1994, it should be lost under Place assimilation, and if [lateral] is under Sonorant Voicing (Rice & Avery 1991 it should be lost by rules that spread voicing. Yet in some languages lateral survives such spreading intact. Facts like these argue against a universal attachment of [lateral] under either Coronal or Sonorant Voicing, and in favour of an account in terms of markedness constraints on feature-co-occurrence (Padgett 2000. The core of an OT account is that IFIDENTLAT is ranked above whatever causes neutralization, such as SHARE-F or *CODAF. laterality will survive. If these rankings are reversed, we derive languages in which laterality is lost. The other significant factor is markedness. High-ranked feature co-occurrence constraints like *LATDORSAL can block spreading from affecting laterals at all.

    2009-12-01

    Full Text Available In the spring of 2009 (April/May the Denver Zoological Foundation in collaboration with the Mongolian Academy of Sciences conducted a fi eld coprological assessment feasibility study at the Ikh Nart Nature Reserve in southeastern Mongolia. Our initial effort was directed at fi nding simple methodologies that would work consistently in the fi eld for identifying some of the enteric parasites for argali sheep ( Ovis ammon and Siberian ibex ( Capra sibirica , and then to compare these to samples from local nomad domestic fat-tailed sheep ( Ovis aries and cashmere goats ( Capra hircus . Direct fecal examination yielded less eggs than the fl otation techniques, but was still felt to be useful as a quick screening tool. From the fl otation techniques we settled on using sugar because it appeared to yield the most eggs and sugar is readily available in Mongolia. We successfully recovered Entamoeba sp., Eimeria spp., trichostrongyles, large trichostrongyle species, Trichuris ovis and Strongyloides papillosus . We are using the digital images we captured to create a fi eld guide for common enteric parasites found in wildlife and domestics ungulates found in the reserve. In the future, we plan to use the fi eld guide and the quantitative modi fi ed McMaster technique to compare parasite egg-type numbers in both wild and domestic ungulates during different seasons.

  3. Optimization of OT-MACH Filter Generation for Target Recognition

    Johnson, Oliver C.; Edens, Weston; Lu, Thomas T.; Chao, Tien-Hsin

    2009-01-01

    An automatic Optimum Trade-off Maximum Average Correlation Height (OT-MACH) filter generator for use in a gray-scale optical correlator (GOC) has been developed for improved target detection at JPL. While the OT-MACH filter has been shown to be an optimal filter for target detection, actually solving for the optimum is too computationally intensive for multiple targets. Instead, an adaptive step gradient descent method was tested to iteratively optimize the three OT-MACH parameters, alpha, beta, and gamma. The feedback for the gradient descent method was a composite of the performance measures, correlation peak height and peak to side lobe ratio. The automated method generated and tested multiple filters in order to approach the optimal filter quicker and more reliably than the current manual method. Initial usage and testing has shown preliminary success at finding an approximation of the optimal filter, in terms of alpha, beta, gamma values. This corresponded to a substantial improvement in detection performance where the true positive rate increased for the same average false positives per image.

  11. Consonant harmony in Nilotic: contrastive specifications and Stratal OT

    Directory of Open Access Journals (Sweden)

    Sara Mackenzie

    2016-07-01

    Full Text Available Through analyses of dental harmony in four Nilotic languages, this paper argues both for contrastive representations and for a stratal version of Optimality Theory. Dholuo, Päri, Shilluk and Anywa all have dental harmony patterns which bar the co-occurrence of dental and alveolar segments. Details of the dental harmony patterning vary between languages and are tied to contrasts in the inventory. In Anywa, harmony is non-structure-preserving and an allophonic dental nasal surfaces in harmonic forms. This pattern can be analyzed in a stratal model of OT but leads to a ranking paradox if only a single level of evaluation is used. Further support for a stratal analysis can be found in the interaction between harmony and consonant mutation processes in the four languages. In Dholuo, harmony applies at the stem level and consonant mutation results in disharmonic surface forms in morphologically complex words. In Anywa, harmony applies later, at the word level, and words formed through consonant mutation must obey the dental harmony restrictions.

  15. Oxytocin (OT) and arginine-vasopressin (AVP) act on OT receptors and not AVP V1a receptors to enhance social recognition in adult Syrian hamsters (Mesocricetus auratus).

    Science.gov (United States)

    Song, Zhimin; Larkin, Tony E; Malley, Maureen O'; Albers, H Elliott

    2016-05-01

    Social recognition is a fundamental requirement for all forms of social relationships. A majority of studies investigating the neural mechanisms underlying social recognition in rodents have investigated relatively neutral social stimuli such as juveniles or ovariectomized females over short time intervals (e.g., 2h). The present study developed a new testing model to study social recognition among adult males using a potent social stimulus. Flank gland odors are used extensively in social communication in Syrian hamsters and convey important information such as dominance status. We found that the recognition of flank gland odors after a 3min exposure lasted for at least 24h, substantially longer than the recognition of other social cues in rats and mice. Intracerebroventricular injections of OT and AVP prolonged the recognition of flank gland odor for up to 48h. Selective OTR but not V1aR agonists, mimicked these enhancing effects of OT and AVP. Similarly, selective OTR but not V1aR antagonists blocked recognition of the odors after 20min. In contrast, the recognition of non-social stimuli was not blocked by either the OTR or the V1aR antagonists. Our findings suggest both OT and AVP enhance social recognition via acting on OTRs and not V1aRs and that the recognition enhancing effects of OT and AVP are limited to social stimuli.

Inadequate nipple care in the at-risk years leads to ductal obstruction preventing the elimination of carcinogens from the breast. The regular production of oxytocin (OT) from nipple stimulation would cause contraction of the myoepithelial cells, relieving acinal gland distension and aiding the active elimination of carcinogenic fluid from the breast. Mechanical breast pump stimulation causes an increase in plasma OT levels in the luteal but not in the follicular phase of the menstrual cycle. OT production upon nipple stimulation in the luteal phase of premenopausal, non-lactating women may be protective against the high rates of mitotic breast cell division noted at this time via the potential to block the effect of oestrogen. The epidemiology of breast cancer suggests that lengthy lactation time is beneficial. Sexual activity in nulliparous women also protects and OT levels have been shown to rise with orgasm in women and in men. OT systems in the brain are intricately linked to oestrogen and progesterone levels, and it is possible that these hormones may modify the OT secretory response both centrally and through an effect on the sensitivity of the breast. OT production with nipple care and in sex and lactation, and the reduction in cycling ovarian hormones that occurs with pregnancy, may all be important preventative factors in the development of breast cancer both pre- and post-menopausally.

    This paper studies the effect of non-ideal estimation of channel state information (CSI) on the performance of output-threshold maximal-ratio combining (OT-MRC) diversity scheme in the presence of co-channel interference as well as white noise. The channel fading envelopes are assumed to follow slowly varying flat Rayleigh model. New closed-form expressions for the combined signal-to-interference-plus-noise ratio (SINR) distribution and outage probability performance are presented. Performance comparisons between the conventional MRC and OT-MRC for the system model described above are provided. © 2010 IEEE.

    2003-01-01

    °Microelectromechanical systems (MEMS) have enormous potential to contribute in diverse fields such as automotive, health care, aerospace, consumer products, and biotechnology, but successful commercial applications of MEMS are still small in number. Reliability of MEMS is a major impediment to the commercialization of laboratory prototypes. Due to the multitude of MEMS applications and the numerous processing and packaging steps, MEMS are exposed to a variety of environmental conditions, making the prediction of operational reliability difficult. In this paper, we investigate the effects of operating temperature on the in-use adhesive failure of electrostatically actuated MEMS microcantilevers coated with octadecyltrichlorosilane (OTS) films. The cantilevers are subjected to repeated temperature cycles and electrostatically actuated at temperatures between 25°C and 300°C in ambient air. The experimental results indicate that temperature cycling of the OTS coated cantilevers in air reduces the sticking probability of the microcantilevers. The sticking probability of OTS coated cantilevers was highest during heating, which decreased during cooling, and was lowest during reheating. Modifications to the OTS release method to increase its yield are also discussed.

    To examine the feasibility and benefits of the Merging Yoga and Occupational Therapy (MY-OT) intervention. This is the primary analysis of a non-controlled pretest-posttest pilot study to understand the feasibility and impact of MY-OT on balance, balance self-efficacy, and fall risk factor management in people with chronic stroke. University research laboratory. People with chronic stroke were included in the study if they: had sustained a fall or had fear of falling, were able to stand, and hand impaired balance and were at risk for falls (≤46 on the Berg Balance Scale (BBS)). Individuals completed an 8 week intervention that included 16 sessions of both yoga and group occupational therapy (OT). Yoga included physical postures, breathing exercises, and meditation. OT focused on post-stroke fall risk factor management. The BBS was used to assess balance, the Activities-specific Balance Confidence Scale (ABC) was used to measure balance self-efficacy. Five fall risk factor management scales were used. Overall, the intervention was considered feasible, as individuals were able to safely complete the intervention with little attrition and high attendance. Balance improved by 30% (p=0.002). Balance self-efficacy improved by 15% (p=0.034). Each of the five fall risk factor management scales improved, but only two significantly improved (Fall Prevention and Management Questionnaire, 29%, p=0.004 and Fall Prevention Strategy Survey, 42%, p=0.032). The results demonstrate that MY-OT is a potential intervention to improve multiple fall related outcomes for people with stroke. Therapists may consider these interventions for people with stroke, but additional research is warranted. Copyright © 2016 Elsevier Ltd. All rights reserved.

    CDKN1C and KCNQ1OT1 are imprinted genes that might be potential regulators of placental development. This study investigated placental expressions of CDKN1C and KCNQ1OT1 in monozygotic twins with and without selective intrauterine growth restriction (sIUGR). Seventeen sIUGR and fifteen normal monozygotic(MZ) twin pairs were examined. Placental mRNA expressions of CDKN1C and KCNQ1OT1 were detected by real-time fluorescent quantitative PCR. CDKN1C protein expression was detected by immunohistochemical assay and Western-blotting. In the sIUGR group, smaller fetuses had a smaller share of the placenta, and CDKN1C protein expression was significantly increased while KCNQ1OT1 mRNA expression was significantly decreased. The CDKN1C/KCNQ1OT1 mRNA ratio was lower in the larger fetus than in the smaller fetus (p < .05). In the control group, CDKN1C protein expression showed no difference between larger and smaller fetuses, while KCNQ1OT1 mRNA expression was significantly lower in the larger fetus, and the CDKN1C/KCNQ1OT1 mRNA ratio was higher in the larger fetus than in the smaller fetus (p < .05). Our findings showed that pathogenesis of sIUGR may be related to the co-effect of the up-regulated protein expression of CDKN1C and down-regulated mRNA expression of KCNQ1OT1 in the placenta.

    Prohibitin is essential for intracellular homeostasis and stabilization of mitochondrial respiratory chain complexes. To explore its functions during spermiogenesis of Octopus tankahkeei (O. tankahkeei), we have cloned and sequenced the cDNA of this mammalian PHB homologue (termed ot-PHB) from the testes of O. tankahkeei. The 1165 bp ot-phb cDNA contains a 100 bp 5' UTR, a 882 bp open reading frame and a 183 bp 3' UTR. The putative ot-PHB protein owns a transmembrane domain from 6 to 31 amino acid (aa) and a putative PHB domain from 26 to 178 aa. Protein alignment demonstrated that ot-PHB had 73.3, 73.6, 74.0, 75.1, and 45.4% identity with its homologues in Homo sapiens, Mus muculus, Danio rerio, Xenopus tropicalis and Trypanosoma brucei, respectively. Tissue distribution profile analysis revealed its presence in all the tissues examined. In situ hybridization in spermiogenic cells demonstrated that ot-phb was expressed moderately at the beginning of the spermiogenesis. The abundance of transcripts increased in intermediate spermatids and in drastically remodeling final spermatids. In mature spermatozoa, the residuary transcripts concentrated around the chondriosomal mantle where mitochondria assemble around. In summary, the expression of ot-phb during spermiogenesis implicates a potential function of this protein during mitochondrial ubiquitination. It is the first time to implicate the role of prohibitin in cephalopod spermiogenesis.

  15. The reactivity of anion-exchange resins by applying OT-for-OH exchange reaction in the equilibrium state

    1996-01-01

    In order to reveal the behavior of hydroxyl group in isotope exchange reaction, OT-for-OH exchange reaction between each anion-exchange resin (OH - form) and tritiated water (abbreviated as HTO water below) was observed at 80degC under the equilibrium. Anion-exchange resins used were Amberlite IRA-400, IRA-410 (both strongly basic), and IRA-94S (weakly basic). It can be thought that an HTO molecule dissociates into H + +OT - (or T + +OH - ). The activity of each resin based on OT-for-OH exchange reaction was measured with a liquid scintillation counter. From the above-mentioned, the following five were found. Isotope exchange reaction as 'atomic group' occurred between the OH group in each anion-exchange resin and the OT group in HTO water. The reactivity of strongly basic anion-exchange resin is larger than that of weakly basic one. The ratio of the reactivity of these resins can roughly be expressed as follows: (IRA-410): (IRA-400): (IRA-94S)=42: 7: 1. The degree of OT-for-OH exchange reaction may be smaller than that of T-for-H exchange reaction. The method used and results obtained in this work may be helpful to obtain the data for the prevention of T-contamination, especially to obtain the data from certain atomic groups including T.

  20. Trehalose-6-Phosphate-Mediated Toxicity Determines Essentiality of OtsB2 in Mycobacterium tuberculosis In Vitro and in Mice.

    Directory of Open Access Journals (Sweden)

    Jan Korte

    2016-12-01

    Full Text Available Trehalose biosynthesis is considered an attractive target for the development of antimicrobials against fungal, helminthic and bacterial pathogens including Mycobacterium tuberculosis. The most common biosynthetic route involves trehalose-6-phosphate (T6P synthase OtsA and T6P phosphatase OtsB that generate trehalose from ADP/UDP-glucose and glucose-6-phosphate. In order to assess the drug target potential of T6P phosphatase, we generated a conditional mutant of M. tuberculosis allowing the regulated gene silencing of the T6P phosphatase gene otsB2. We found that otsB2 is essential for growth of M. tuberculosis in vitro as well as for the acute infection phase in mice following aerosol infection. By contrast, otsB2 is not essential for the chronic infection phase in mice, highlighting the substantial remodelling of trehalose metabolism during infection by M. tuberculosis. Blocking OtsB2 resulted in the accumulation of its substrate T6P, which appears to be toxic, leading to the self-poisoning of cells. Accordingly, blocking T6P production in a ΔotsA mutant abrogated otsB2 essentiality. T6P accumulation elicited a global upregulation of more than 800 genes, which might result from an increase in RNA stability implied by the enhanced neutralization of toxins exhibiting ribonuclease activity. Surprisingly, overlap with the stress response caused by the accumulation of another toxic sugar phosphate molecule, maltose-1-phosphate, was minimal. A genome-wide screen for synthetic lethal interactions with otsA identified numerous genes, revealing additional potential drug targets synergistic with OtsB2 suitable for combination therapies that would minimize the emergence of resistance to OtsB2 inhibitors.

    antibody 237, developed to a spontaneous murine fibrosarcoma, was shown to be directed to murine podoplanin (OTS8) with truncated Tn O-glycans. Our understanding of such cancer-specific auto-antibodies to truncated glycoforms of glycoproteins is limited. Here we have investigated immunogenicity...... of a chemoenzymatically produced Tn-glycopeptide derived from the putative murine podoplanin O-glycopeptide epitope. We found that the Tn O-glycopeptide was highly immunogenic in mice and produced a Tn-glycoform specific response with no reactivity against unglycosylated peptides or the O-glycopeptide with extended O......-glycan (STn and T glycoforms). The immunodominant epitope was strictly dependent on the peptide sequence, required Tn at a specific single Thr residue (Thr(77)), and antibodies to the epitope were not found in naive mice. We further tested a Tn O-glycopeptide library derived from human podoplanin...

  2. Entraining IDyOT: timing in the information dynamics of thinking

    Directory of Open Access Journals (Sweden)

    Jamie Forth

    2016-10-01

    Full Text Available We present a novel hypothetical account of entrainment in music and language, in context of the Information Dynamics of Thinking model, IDyOT. The extended model affords an alternative view of entrainment, and its companion term, pulse, from earlier accounts. The model is based on hiearchical, statistical prediction, modeling expectations of both what an event will be and when it will happen. As such,it constitutes a kind of predictive coding, with a particular novel hypothetical implementation. Here, we focus on the model’s mechanism for predicting when a perceptual event will happen, given an existing sequence of past events, which maybe musical or linguistic. We propose a range of tests to validate or falsify the model, at various different levels of abstraction, and argue that computational modelling in particular, and this model in particular, can offer a means of providing limited but useful evidence for evolutionary hypotheses.

  7. Effect of Ozone Therapy (OT on Healing of Colonic Anastomosis in a Rat Model of Peritonitis

    Directory of Open Access Journals (Sweden)

    Başak Erginel

    2014-09-01

    Full Text Available Background: Ozone is a three-oxygen molecule (O3. Ozone therapy (OT is systematically effective when pathological inflammatory and immunologic processes are activated. Among of these conditions are wound healing, macular degeneration related to aging, and conditions that are ischemic or infectious. Aims: The aim of this study was to determine the effects of OT on wound healing of intestinal anastomosis in the presence of peritonitis in a rat model. Study Design: Animal experimentation. Methods: A total of 40 Wistar albino rats were randomized into four groups (n=10 including: sham (S, peritonitis (P, ozone 0 (O0, and ozone 24 (O24. In group S, only cecal dissection was carried out. The S group had only a cecal dissection and intestinal anastomosis performed, but no peritonitis. In all other groups, cecal ligation and puncture (CLP followed the cecal dissection to induce bacterial peritonitis. 24 h after puncture, a cecal resection and ileocolic anastomosis were performed. In group P, 24 h after CLP, a cecal resection and ileocolic anastomosis were performed and no ozone was administered. In group O0, immediately after the anastomosis, and in group O24, starting 24 hours after the anastomosis, an intraperitoneal 1 mg/kg/day ozone administration was applied for seven days. On the seventh day the animals were sacrificed, the anastomotic bursting pressures (BP and the hydroxyproline values of the anastomotic tissues were measured, and histopathologic examination of the anastomotic segment was carried out. Results: The highest BP was in group S, with 211±23.13 mmHg. The mean BP of group P was 141±56.25 mmHg, which was significantly lower than in the other two peritonitis groups that received ozone therapy, group O0 and O24, where it was 192±22 and 166±45 mmHg, respectively (p0.05. Histopathologic analyses of the anastomotic segments determined there was significantly more oedema and necrosis in the control group rats, and collagen deposition in

    Full Text Available Trehalose-6-phosphate phosphatase (OtsB2 is involved in the OtsAB trehalose synthesis pathway to produce free trehalose and is strictly essential for mycobacterial growth. We wished to determine the effects of OtsB2 expression on mycobacterial phenotypes such as growth, phagocytosis and survival in macrophages. Mycobacterium bovis-BCG (BCG over-expressing OtsB2 were able to better survive in stationary phase. Over-expression of OtsB2 led to a decrease in phagocytosis but not survival in THP-1 macrophage-like cells, and this was not due to a decrease in general macrophage phagocytic activity. Surprisingly, when we investigated macrophage-mycobacterial interactions by flow cytometry and atomic force microscopy, we discovered that BCG over-expressing OtsB2 have stronger binding to THP-1 cells than wild-type BCG. These results suggest that altering OtsB2 expression has implications for mycobacterial host-pathogen interactions. Macrophage-mycobacteria phagocytic interactions are complex and merit further study.

    Full Text Available Taipans (Oxyuranus spp. are elapids with highly potent venoms containing presynaptic (β and postsynaptic (α neurotoxins. O. temporalis (Western Desert taipan, a newly discovered member of this genus, has been shown to possess venom which displays marked in vitro neurotoxicity. No components have been isolated from this venom. We describe the characterization of α-elapitoxin-Ot1a (α-EPTX-Ot1a; 6712 Da, a short-chain postsynaptic neurotoxin, which accounts for approximately 30% of O. temporalis venom. α-Elapitoxin-Ot1a (0.1–1 µM produced concentration-dependent inhibition of indirect-twitches, and abolished contractile responses to exogenous acetylcholine and carbachol, in the chick biventer cervicis nerve-muscle preparation. The inhibition of indirect twitches by α-elapitoxin-Ot1a (1 µM was not reversed by washing the tissue. Prior addition of taipan antivenom (10 U/mL delayed the neurotoxic effects of α-elapitoxin-Ot1a (1 µM and markedly attenuated the neurotoxic effects of α-elapitoxin-Ot1a (0.1 µM. α-Elapitoxin-Ot1a displayed pseudo-irreversible antagonism of concentration-response curves to carbachol with a pA2 value of 8.02 ± 0.05. De novo sequencing revealed the main sequence of the short-chain postsynaptic neurotoxin (i.e., α-elapitoxin-Ot1a as well as three other isoforms found in O. temporalis venom. α-Elapitoxin-Ot1a shows high sequence similarity (i.e., >87% with other taipan short-chain postsynaptic neurotoxins.

    Using improved seismic, bathymetric, satellite gravity and other geophysical data, we investigated the seismicity patterns and focal mechanisms of earthquakes in oceanic lithosphere off the trenches of the world that are large enough to be well recorded at teleseismic distances. A number of prominent trends are apparent, some of which have been previously recognized based on more limited data [1], and some of which are largely new [2-5]: (1) The largest events and the highest seismicity rates tend to occur where Mesozoic incoming plates are subducting at high rates (e.g., those in the western Pacific and the Banda segment of Indonesia). The largest events are predominantly shallow normal faulting (SNF) earthquakes. Less common are reverse-faulting (RF) events that tend to be deeper and to be present along with SNF events where nearby seamounts, seamount chains and other volcanic features are subducting [Seno and Yamanaka, 1996]. Blooms of SNF OR/OTS events usually occur just after and seaward of great interplate thrust (IPT) earthquakes but are far less common after smaller IPT events. (2) Plates subducting at slow rates (Chile, the Ninety East Ridge in Sumatra, and the D’Entrecastaux Ridge in Vanuatu).

    Full Text Available Innovative teaching methods to address emerging practice needs are critical components of effective occupational therapy education. Experiential learning strategies can enhance skill development and translation of knowledge into OT clinical practice. In addition, skills such as coaching may provide important links to health promotion practices. Thirty-two occupational therapy students took part in an experiential project to connect occupational engagement and health for a community of older adults. A pretest/posttest design was used to evaluate program outcomes in student perceived abilities, and narrative reflection papers provided postexperience qualitative information. The students improved in all 10 areas of abilities selfassessment with mean total scores from pretest (M = 42 improving significantly at posttest (M = 58. Themes from reflection papers indicated a positive response to experiential learning and a desire for more opportunities to prepare for clinical practice, including the use of interprofessional training. The students improved in their abilities to use coaching and health promotion strategies through the use of experiential learning methods. Outcomes suggest that experiential learning opportunities are an effective way to enhance student competencies in coaching, improve readiness for wellness programming, and increase student confidence in application of skills in future clinical practice.

    Full Text Available Lichens are symbiotic associations of fungi with microalgae and/or cyanobacteria, which are considered among the slowest growing organisms, with strong tolerance to adverse environmental conditions. There are about 400 genera and 1600 species of lichens and those belonging to the Usnea genus comprise about 360 of these species. Usnea lichens have been used since ancient times as dyes, cosmetics, preservatives, deodorants and folk medicines. The phytochemistry of the Usnea genus includes more than 60 compounds which belong to the following classes: depsides, depsidones, depsones, lactones, quinones, phenolics, polysaccharides, fatty acids and dibenzofurans. Due to scarce knowledge of metabolomic profiles of Usnea species (U. barbata, U. antarctica, U. rubicunda and U. subfloridana, a study based on UHPLC-ESI-OT-MS-MS was performed for a comprehensive characterization of their secondary metabolites. From the methanolic extracts of these species a total of 73 metabolites were identified for the first time using this hyphenated technique, including 34 compounds in U. barbata, 21 in U. antarctica, 38 in U. rubicunda and 37 in U. subfloridana. Besides, a total of 13 metabolites were not identified and reported so far, and could be new according to our data analysis. This study showed that this hyphenated technique is rapid, effective and accurate for phytochemical identification of lichen metabolites and the data collected could be useful for chemotaxonomic studies.

    To investigate the safety and preliminary efficacy of OT-551, a disubstituted hydroxylamine with antioxidant properties, for the treatment of geographic atrophy (GA), the advanced atrophic form of age-related macular degeneration (AMD). The study was a single-center, open-label phase II trial, enrolling 10 participants with bilateral GA. Topical 0.45% OT-551 was administered in one randomly assigned eye three times daily for 2 years. Safety measures were assessed by complete ophthalmic examination, fundus photography, and review of symptoms. The primary efficacy outcome measure was the change in best corrected visual acuity at 24 months. Secondary efficacy measures included changes in area of GA, contrast sensitivity, microperimetry measurements, and total drusen area from baseline. Study drug was well tolerated and was associated with few adverse events. The mean change in BCVA at 2 years was +0.2 ± 13.3 letters in the study eyes and -11.3 ± 7.6 letters in fellow eyes (P = 0.0259). However, no statistically significant differences were found between the study and fellow eyes for all other secondary outcome measures. OT-551 was well tolerated by study participants and was not associated with any serious adverse effects. Efficacy measurements in this small study indicate a possible effect in maintaining visual acuity. However, the absence of significant effects on other outcomes measures in this study suggests that OT-551, in the current concentration and mode of delivery, may have limited or no benefit as a treatment for GA (ClinicalTrials.gov number, NCT00306488).

    Full Text Available Oligotyping is a novel, supervised computational method that classifies closely related sequences into oligotypes (OTs based on subtle nucleotide variations (Eren et al. 2013. Its application to microbial datasets has helped reveal ecological patterns which are often hidden by the way sequence data are currently clustered to define operational taxonomic units (OTUs. Here, we implemented the OT entropy decomposition procedure and its unsupervised version, Minimal Entropy Decomposition (MED; Eren et al. 2014, in the statistical programming language and environment, R. The aims are to facilitate the integration of computational routines, interactive statistical analyses, and visualization into a single framework. In addition, two complementary approaches are implemented: 1 An analytical method (the broken stick model is proposed to help identify oligotypes of low abundance that could be generated by chance alone and 2 a one-pass profiling (OP method, to efficiently identify those OTUs whose subsequent oligotyping would be most promising. These enhancements are especially useful for large datasets, where a manual screening of entropy analysis results and the creation of a full set of OTs may not be feasible. The package and procedures are illustrated by several tutorials and examples.

  16. Transcriptional role of androgen receptor in the expression of long non-coding RNA Sox2OT in neurogenesis.

    Directory of Open Access Journals (Sweden)

    Valentina Tosetti

    Full Text Available The complex architecture of adult brain derives from tightly regulated migration and differentiation of precursor cells generated during embryonic neurogenesis. Changes at transcriptional level of genes that regulate migration and differentiation may lead to neurodevelopmental disorders. Androgen receptor (AR is a transcription factor that is already expressed during early embryonic days. However, AR role in the regulation of gene expression at early embryonic stage is yet to be determinate. Long non-coding RNA (lncRNA Sox2 overlapping transcript (Sox2OT plays a crucial role in gene expression control during development but its transcriptional regulation is still to be clearly defined. Here, using Bicalutamide in order to pharmacologically inactivated AR, we investigated whether AR participates in the regulation of the transcription of the lncRNASox2OTat early embryonic stage. We identified a new DNA binding region upstream of Sox2 locus containing three androgen response elements (ARE, and found that AR binds such a sequence in embryonic neural stem cells and in mouse embryonic brain. Our data suggest that through this binding, AR can promote the RNA polymerase II dependent transcription of Sox2OT. Our findings also suggest that AR participates in embryonic neurogenesis through transcriptional control of the long non-coding RNA Sox2OT.

    The location of M101-OT2015-1 has been serendipitously imaged by numerous telescopes and instruments over the last 15 years (from 2000 to 2015). Our best quality pre-discovery image (seeing of 0.55") is an r-band exposure at -3625 days pre-peak from the Canada-France-Hawaii Telescope (CFHT). The historical optical data for M101-OT was retrieved from the CFHT MegaPrime and CFHT12K/Mosaic, using single and combined exposures, Pan-STARRS-1/GPC1 (PS1), Isaac Newton Telescope/Wide Field Camera (INT/WFC), and Sloan Digital Sky Survey (SDSS) DR 10 (Ahn+ 2014, see V/147). Unfortunately, there are no HST images covering the location of the source. Post-discovery optical magnitudes were obtained from the reported followup astronomer's telegrams (ATels), Liverpool Telescope (LT), the Nordic Optical Telescope (NOT), and the Palomar P48 and P60 telescopes. The infrared data were retrieved from CFHT/WIRCam, UKIRT/WFCAM, and the Spitzer Infrared Array Camera in 3.6 and 4.5um as part of the SPitzer InfraRed Intensive Transients Survey (SPIRITS) (Kasliwal+, 2017ApJ...839...88K). Details of pre-discovery photometry and post-discovery optical photometry may be found in the Appendices Tables 1 and 2, respectively. We obtained spectra of M101-OT using a range of facilities in 2015 Feb-Jul. (3 data files).

    OTF (Off The Shelf) quadro copter systems provide a cost effective (below 2000 Euro), flexible and mobile platform for high resolution point cloud mapping. Various studies showed the full potential of these small and flexible platforms. Especially in very tight and complex 3D environments the automatic obstacle avoidance, low copter weight, long flight times and precise maneuvering are important advantages of these small OTS systems in comparison with larger octocopter systems. This study examines the potential of the DJI Phantom 4 pro series and the Phantom 3A series for within-stand and forest tree crown 3D point cloud mapping using both within stand oblique imaging in different altitude levels and data captured from a nadir perspective. On a test site in Brandenburg/Germany a beach crown was selected and measured with 3 different altitude levels in Point Of Interest (POI) mode with oblique data capturing and deriving one nadir mosaic created with 85/85 % overlap using Drone Deploy automatic mapping software. Three different flight campaigns were performed, one in September 2016 (leaf-on), one in March 2017 (leaf-off) and one in May 2017 (leaf-on) to derive point clouds from different crown structure and phenological situations - covering the leaf-on and leafoff status of the tree crown. After height correction, the point clouds where used with GPS geo referencing to calculate voxel based densities on 50 × 10 × 10 cm voxel definitions using a topological network of chessboard image objects in 0,5 m height steps in an object based image processing environment. Comparison between leaf-off and leaf-on status was done on volume pixel definitions comparing the attributed point densities per volume and plotting the resulting values as a function of distance to the crown center. In the leaf-off status SFM (structure from motion) algorithms clearly identified the central stem and also secondary branch systems. While the penetration into the crown

    Ribonuclease P (RNase P) is a ribonucleoprotein complex involved in the processing of the 5'-leader sequence of precursor tRNA (pre-tRNA). Our earlier study revealed that RNase P RNA (pRNA) and five proteins (PhoPop5, PhoRpp38, PhoRpp21, PhoRpp29, and PhoRpp30) in the hyperthermophilic archaeon Pyrococcus horikoshii OT3 reconstituted RNase P activity that exhibits enzymatic properties like those of the authentic enzyme. In present study, we investigated involvement of the individual proteins in RNase P activity. Two particles (R-3Ps), in which pRNA was mixed with three proteins, PhoPop5, PhoRpp30, and PhoRpp38 or PhoPop5, PhoRpp30, and PhoRpp21 showed a detectable RNase P activity, and five reconstituted particles (R-4Ps) composed of pRNA and four proteins exhibited RNase P activity, albeit at reduced level compared to that of the reconstituted particle (R-5P) composed of pRNA and five proteins. Time-course analysis of the RNase P activities of R-4Ps indicated that the R-4Ps lacking PhoPop5, PhoRpp21, or PhoRpp30 had virtually reduced activity, while omission of PhoRpp29 or PhoRpp38 had a slight effect on the activity. The results indicate that the proteins contribute to RNase P activity in order of PhoPop5 > PhoRpp30 > PhoRpp21 > PhoRpp29 > PhoRpp38. It was further found that R-4Ps showed a characteristic Mg2+ ion dependency approximately identical to that of R-5P. However, R-4Ps had optimum temperature of around at 55 degrees C which is lower than 70 degrees C for R-5P. Together, it is suggested that the P. horikoshii RNase P proteins are predominantly involved in optimization of the pRNA conformation, though they are individually dispensable for RNase P activity in vitro.

    Full Text Available Celem poniższej pracy było przedstawienie dylematów związanych ze stosowaniem leków poprawiających funkcje poznawcze przy obecności innych schorzeń u ludzi starszych. Ze względu na powszechną w starości polipatologię otępienie, będące jednym z najistotniejszych problemów medycznych w tym okresie życia, rzadko występuje jako pojedyncze schorzenie – zwykle współistnieje z innymi chorobami. Leczenie otępienia jest zwykle połączone z terapią innych jednostek chorobowych, co wiąże się ze zwiększonym ryzykiem interakcji lekowych oraz działań niepożądanych. Dodatkowo ryzyko tych działań wzrasta z powodu zmian w farmakokinetyce wynikających z gorszej dystrybucji leków w organizmie oraz pogarszającej się z wiekiem wydolności wielonarządowej, czego konsekwencją może być upośledzony metabolizm i wydalanie leków. Spośród stosowanych w leczeniu otępienia inhibitorów acetylocholinesterazy interakcje najczęściej dotyczą donepezilu, co spowodowane jest jego metabolizmem w wątrobie przy udziale cytochromu P450, który równocześnie uczestniczy w metabolizmie wielu innych leków wykorzystywanych w terapii różnych schorzeń wieku starczego. Przeciwwskazaniami do stosowania inhibitorów acetylocholinesterazy są przede wszystkim: ciężka niewydolność wątroby, zespół chorego węzła zatokowego, zaburzenia rytmu i przewodnictwa, czynna choroba wrzodowa żołądka lub dwunastnicy, choroby powodujące utrudnienie odpływu moczu, napady drgawkowe, astma oskrzelowa/przewlekła obturacyjna choroba płuc. Działania niepożądane leków występują u kilku do kilkudziesięciu procent pacjentów, a u części z nich stanowią przeciwwskazania do kontynuowania terapii. Problem interakcji lekowych i działań niepożądanych jest często marginalizowany w leczeniu starszych pacjentów z otępieniem.

    A hyperthermophilic adenylosuccinate synthetase from P. horikoshii OT3, which is 90–120 amino acids shorter than those from the vast majority of organisms, was expressed, purified and crystallized and X-ray diffraction data were collected to 2.5 Å resolution. Adenylosuccinate synthetase (AdSS) is a ubiquitous enzyme that catalyzes the first committed step in the conversion of inosine monophosphate (IMP) to adenosine monophosphate (AMP) in the purine-biosynthetic pathway. Although AdSS from the vast majority of organisms is 430–457 amino acids in length, AdSS sequences isolated from thermophilic archaea are 90–120 amino acids shorter. In this study, crystallographic studies of a short AdSS sequence from Pyrococcus horikoshii OT3 (PhAdSS) were performed in order to reveal the unusual structure of AdSS from thermophilic archaea. Crystals of PhAdSS were obtained by the microbatch-under-oil method and X-ray diffraction data were collected to 2.50 Å resolution. The crystal belonged to the trigonal space group P3 2 12, with unit-cell parameters a = b = 57.2, c = 107.9 Å. There was one molecule per asymmetric unit, giving a Matthews coefficient of 2.17 Å 3 Da −1 and an approximate solvent content of 43%. In contrast, the results of native polyacrylamide gel electrophoresis and analytical ultracentrifugation showed that the recombinant PhAdSS formed a dimer in solution

    Full Text Available KCNQ1OT1 is located in the region with the highest number of genes showing genomic imprinting, but the mechanisms controlling the genes under its influence have not been fully elucidated. Therefore, we conducted a comparative analysis of the KCNQ1/KCNQ1OT1-CDKN1C region to study its conservation across the best assembled eutherian mammalian genomes sequenced to date and analyzed potential elements that may be implicated in the control of genomic imprinting in this region. The genomic features in these regions from human, mouse, cattle, and dog show a higher number of genes and CpG islands (detected using cpgplot from EMBOSS, but lower number of repetitive elements (including short interspersed nuclear elements and long interspersed nuclear elements, compared with their whole chromosomes (detected by RepeatMasker. The KCNQ1OT1-CDKN1C region contains the highest number of conserved noncoding sequences (CNS among mammals, where we found 16 regions containing about 38 different highly conserved repetitive elements (using mVista, such as LINE1 elements: L1M4, L1MB7, HAL1, L1M4a, L1Med, and an LTR element: MLT1H. From these elements, we found 74 CNS showing high sequence identity (>70% between human, cattle, and mouse, from which we identified 13 motifs (using Multiple Em for Motif Elicitation/Motif Alignment and Search Tool with a significant probability of occurrence, 3 of which were the most frequent and were used to find transcription factor–binding sites. We detected several transcription factors (using JASPAR suite from the families SOX, FOX, and GATA. A phylogenetic analysis of these CNS from human, marmoset, mouse, rat, cattle, dog, horse, and elephant shows branches with high levels of support and very similar phylogenetic relationships among these groups, confirming previous reports. Our results suggest that functional DNA elements identified by comparative genomics in a region densely populated with imprinted mammalian genes may be

    1994-08-01

    Biocatalytic transformations in reversed micelles formed by anionic surfactant Aerosol OT in octane have been studied at high pressures by an example of alpha-chymotrypsin-catalyzed hydrolysis of N-carbobenzoxy-L-tyrosine p-nitrophenyl ester and N-succinyl-L-phenylalanine p-nitroanilide. For the first time it has been found that the enzyme retains high activity in these water-in-oil microemulsions up to a pressure of 2 kbar. The value of the activation volume (delta V*) for the enzyme reactions shows a dependence on the water content in the system. When the size of the micellar aqueous inner cavity (as evaluated at 1 atm) approaches the molecular size of alpha-chymotrypsin, delta V* becomes significantly different from the value in aqueous solution and in the micelles with a larger size. Possibilities of regulating the enzyme activity by pressure in systems with a low content of water are discussed.

  11. A genome-wide association study of bipolar disorder with comorbid eating disorder replicates the SOX2-OT region.

    2016-01-01

    Bipolar disorder is a heterogeneous mood disorder associated with several important clinical comorbidities, such as eating disorders. This clinical heterogeneity complicates the identification of genetic variants contributing to bipolar susceptibility. Here we investigate comorbidity of eating disorders as a subphenotype of bipolar disorder to identify genetic variation that is common and unique to both disorders. We performed a genome-wide association analysis contrasting 184 bipolar subjects with eating disorder comorbidity against both 1370 controls and 2006 subjects with bipolar disorder only from the Bipolar Genome Study (BiGS). The most significant genome-wide finding was observed bipolar with comorbid eating disorder vs. controls within SOX2-OT (p=8.9×10(-8) for rs4854912) with a secondary peak in the adjacent FXR1 gene (p=1.2×10(-6) for rs1805576) on chromosome 3q26.33. This region was also the most prominent finding in the case-only analysis (p=3.5×10(-7) and 4.3×10(-6), respectively). Several regions of interest containing genes involved in neurodevelopment and neuroprotection processes were also identified. While our primary finding did not quite reach genome-wide significance, likely due to the relatively limited sample size, these results can be viewed as a replication of a recent study of eating disorders in a large cohort. These findings replicate the prior association of SOX2-OT with eating disorders and broadly support the involvement of neurodevelopmental/neuroprotective mechanisms in the pathophysiology of both disorders. They further suggest that different clinical manifestations of bipolar disorder may reflect differential genetic contributions and argue for the utility of clinical subphenotypes in identifying additional molecular pathways leading to illness.

  18. Life-cycle and genome of OtV5, a large DNA virus of the pelagic marine unicellular green alga Ostreococcus tauri.

    Directory of Open Access Journals (Sweden)

    Evelyne Derelle

    Full Text Available Large DNA viruses are ubiquitous, infecting diverse organisms ranging from algae to man, and have probably evolved from an ancient common ancestor. In aquatic environments, such algal viruses control blooms and shape the evolution of biodiversity in phytoplankton, but little is known about their biological functions. We show that Ostreococcus tauri, the smallest known marine photosynthetic eukaryote, whose genome is completely characterized, is a host for large DNA viruses, and present an analysis of the life-cycle and 186,234 bp long linear genome of OtV5. OtV5 is a lytic phycodnavirus which unexpectedly does not degrade its host chromosomes before the host cell bursts. Analysis of its complete genome sequence confirmed that it lacks expected site-specific endonucleases, and revealed the presence of 16 genes whose predicted functions are novel to this group of viruses. OtV5 carries at least one predicted gene whose protein closely resembles its host counterpart and several other host-like sequences, suggesting that horizontal gene transfers between host and viral genomes may occur frequently on an evolutionary scale. Fifty seven percent of the 268 predicted proteins present no similarities with any known protein in Genbank, underlining the wealth of undiscovered biological diversity present in oceanic viruses, which are estimated to harbour 200Mt of carbon.

    The archaeal phosphoglycerate mutase PH0037 from P. horikoshii OT3 has been crystallized in space group R32, with unit-cell parameters a = 155.62, c = 230.35 Å. A 2.2 Å resolution data was collected at SPring-8 beamline BL26B1. Phosphoglycerate mutases catalyze the interconversion of 2-phosphoglycerate and 3-phosphoglycerate in glycolysis and gluconeogenesis pathways. The archaeal phosphoglycerate mutase PH0037 from Pyrococcus horikoshii OT3 has been overexpressed in Escherichia coli and purified. Crystals were obtained using the oil-microbatch method at 291 K. A native data set extending to a resolution of 2.2 Å has been collected and processed in space group R32. Assuming the presence of a dimer in the asymmetric unit, the V{sub M} value is calculated to be 3.0 Å{sup 3} Da{sup −1}, consistent with the dynamic light-scattering experiment result, which shows a dimeric state of the protein in solution. Molecular-replacement trials using the crystal structure of Bacilllus stearothermophilus phosphoglycerate mutase as a search model did not provide a satisfactory solution, indicating substantially different structures of these two phophoglycerate mutases.

    A putative UDP-N-acetyl-d-mannosamine dehydrogenase from P. horikoshii OT3 has been crystallized in space group P2{sub 1}, with unit-cell parameters a = 80.28, b = 69.24, c = 83.10 Å, β = 114.4°. X-ray diffraction data have been collected to 1.80 Å resolution. A putative UDP-N-acetyl-d-mannosamine dehydrogenase from Pyrococcus horikoshii OT3, an essential enzyme for polysaccharide biosynthesis, has been overexpressed in Escherichia coli and purified. Crystals were obtained using the oil-microbatch method at 291 K. A native data set extending to 1.8 Å resolution has been collected and processed in space group P2{sub 1}. Assuming the presence of a dimer in the asymmetric unit, the V{sub M} value is calculated to be 2.3 Å{sup 3} Da{sup −1}, which is consistent with the result of a dynamic light-scattering experiment that shows a dimeric state of the protein in solution.

  2. Transcriptional analysis and molecular dynamics simulations reveal the mechanism of toxic metals removal and efflux pumps in Lysinibacillus sphaericus OT4b.31

    KAUST Repository

    Shaw, Dario Rangel

    2017-11-23

    Lysinibacillus sphaericus strain OT4b.31 is a bacterium widely applied in bioremediation processes of hydrocarbon and metal polluted environments. In this study, we identified the molecular mechanism underlying the Pb2+ and Cr6+ resistance. Metal uptake and temporal transcription patterns of metal resistance operons were evaluated using reverse-transcribed quantitative PCR amplification. The function of the resistance determinants was studied applying docking and in silico mutagenesis methods. The results revealed that the adaptation of Lysinibacillus sphaericus OT4b.31 to elevated levels of lead and chromium involves the pbr and chr operons which comprise a transcriptional regulatory component (pbrR and chrB) and efflux ATPases (pbrA and chrA) to expel ions from the cytoplasm. Expression of metal resistance genes was constitutive and specifically inducible to the exposure of Pb2+ and Cr6+. The simultaneous presence of cations didn\\'t affect the bioaccumulation of metals, evidencing the multimetal resistance of L. sphaericus. Docking analysis revealed the key metal-protein interactions and the conformational changes after metal or ATP binding. Results showed that residues with aromatic rings or imidazole in the catalytic domain are crucial for metal binding and achievement of the function. To our knowledge, this is the first report of a specific mechanism for lead and chromium resistance in Lysinibacillus genus. From the findings of this study, it is possible to suggest the bacterium as a suitable candidate for rapid toxic metals bioremediation processes.

    The goal of hepatorenal syndrome type 1 (HRS-1) treatment is to improve renal function. Terlipressin, a synthetic vasopressin analogue, is a systemic vasoconstrictor used for the treatment of HRS-1, where it is available. To compare the efficacy of terlipressin plus albumin vs. placebo plus albumin in patients with HRS-1. Pooled patient-level data from two large phase 3, randomised, placebo-controlled studies were analysed for HRS reversal [serum creatinine (SCr) value ≤133 μmol/L], 90-day survival, need for renal replacement therapy and predictors of HRS reversal. Patients received intravenous terlipressin 1-2 mg every 6 hours plus albumin or placebo plus albumin up to 14 days. The pooled analysis comprised 308 patients (terlipressin: n = 153; placebo: n = 155). HRS reversal was significantly more frequent with terlipressin vs. placebo (27% vs. 14%; P = 0.004). Terlipressin was associated with a more significant improvement in renal function from baseline until end of treatment, with a mean between-group difference in SCr concentration of -53.0 μmol/L (P albumin resulted in a significantly higher rate of HRS reversal vs. albumin alone in patients with HRS-1. Terlipressin treatment is associated with improved renal function. (ClinicalTrials.gov identifier: OT-0401, NCT00089570; REVERSE, NCT01143246). © 2017 The Authors.

    To date, there have been few reports analyzing the amino acid requirement for growth of hyperthermophilic archaea. We here found that the hyperthermophilic archaeon Pyrococcus horikoshii OT-3 requires Thr, Leu, Val, Phe, Tyr, Trp, His and Arg in the medium for growth, and shows slow growth in medium lacking Met or Ile. This largely corresponds to the presence, or absence, of genes related to amino acid biosynthesis in its genome, though there are exceptions. The amino acid requirements were dramatically lost by addition of D-isomers of Met, Leu, Val, allo-Ile, Phe, Tyr, Trp and Arg. Tracer analysis using (14)C-labeled D-Trp showed that D-Trp in the medium was used as a protein component in the cells, suggesting the presence of D-amino acid metabolic enzymes. Pyridoxal 5'-phosphate (PLP)-dependent racemase activity toward Met, Leu and Phe was detected in crude extract of P. horikoshii and was enhanced in cells grown in the medium supplemented with D-amino acids, especially D-allo-Ile. The gene encoding the racemase was narrowed down to one open reading frame on the basis of enzyme purification from P. horikoshii cells, and the recombinant enzyme exhibited PLP-dependent racemase activity toward several amino acids, including Met, Leu and Phe, but not Pro, Asp or Glu. This is the first report showing the presence in a hyperthermophilic archaeon of a PLP-dependent amino acid racemase with broad substrate specificity that is likely responsible for utilization of D-amino acids for growth.

    A truncated form of biotin carboxyl carrier protein containing the C-terminal half fragment (BCCPΔN76) and the biotin protein ligase (BPL) with the mutation R48A (BPL*) or the double mutation R48A K111A (BPL**) were successfully cocrystallized in the presence of ATP and biotin. The BPL*–BCCPΔN76 and BPL**–BCCPΔN76 crystals belong to space group P2 1 and diffract X-rays to 2.7 and 2.0 Å resolution, respectively. Biotin protein ligase (BPL) catalyses the biotinylation of the biotin carboxyl carrier protein (BCCP) subunit of acetyl-CoA carboxylase. To elucidate the exact details of the protein–protein interactions in the biotinylation function, the C-terminal half fragment of BCCP (BCCPΔN76), the R48A mutant of BPL (BPL*) and the R48A K111A double mutant of BPL (BPL**), all of which are from Pyrococcus horikoshii OT3, have been expressed, purified and successfully cocrystallized. Cocrystals of the BPL*–BCCPΔN76 and BPL**–BCCPΔN76 complexes as well as crystals of BPL*, BPL** and BCCPΔN76 were obtained by the oil-microbatch method using PEG 20 000 as a precipitant at 295 K. Complete X-ray diffraction data sets for BPL*–BCCPΔN76 and BPL**–BCCPΔN76 crystals were collected at 100 K to 2.7 and 2.0 Å resolution, respectively, using synchrotron radiation. They belong to the monoclinic space group P2 1 , with similar unit-cell parameters a = 69.85, b = 63.12, c = 75.64 Å, β = 95.9°. Assuming two subunits of the complex per asymmetric unit gives a V M value of 2.45 Å 3 Da −1 and a solvent content of 50%

Como metodología se asume la fenomenología a la territorialidad cotidiana del habitante, explícitamente desde dos variables: contexto socioeconómico y vínculos territoriales. A partir de allí se consolidaron universos de análisis e interpretación sobre la territorialidad del sujeto que dan cuenta de fricciones y/o conflictos espaciales con respecto a la política pública territorial del municipio de Pereira, en medio de la ejecución de programas y proyectos de gestión y planificación territorial con un denotado carácter hegemónico. Con ello se despeja un panorama crítico reflexivo alrededor de la implementación de estas políticas y al desarrollo sostenible territorial.

    Full Text Available Immune phenomena during the preimplantation period of pregnancy are poorly understood. The aim of our study was to assess the capacity for antigen presentation of splenic antigen-presenting cells (APCs derived from pregnant and pseudopregnant mice in in vitro conditions. Therefore, sorted CD11c+ dendritic cells and macrophages F4/80+ and CD11b+ presenting ovalbumin (OVA were cocultured with CD4+ T cells derived from OT-II mice’s (C57BL6/J-Tg(TcraTcrb1100Mjb/J spleen. After 132 hours of cell culture, proliferation of lymphocytes (ELISA-BrdU, activation of these cells (flow cytometry, cytokine profile (ELISA, and influence of costimulatory molecules blocking on these parameters were measured. We did not detect any differences in regulation of Th1/Th2 cytokine balance. CD86 seems to be the main costimulatory molecule involved in the proliferation response but CD80 is the main costimulatory molecule influencing cytokine secretion in pregnant mice. In conclusion, this study showed that CD80 and CD86 costimulatory molecules regulate OT-II CD4+ T lymphocyte proliferation and cytokine response in cocultures with antigen-presenting cells derived from pregnant and pseudopregnant mice. The implications of these changes still remain unclear.

    The present research seeks to determine the applicability of simple, rapid and economic methods tor comparing the soil erodability under twelve cultivation systems, and besides to record the features of rill erosion under ale crops in the watershed area of the Otún river. Here the denudation processes are common and affect a large portion of the area. The erodability tests considered (crumb, pinhole, manipulation, rain acceptance, soil loss, shear strenght are related to soil toss with reference to erodable material and the volume of surface flow. These do not seek to quantify the actual or potential soil loss of a place, but can help in the estimation of the variability of soil erodability with the content of surface gravel, the state soil moisture content and time. To predict the advance of rill and interril erosion in bare soil, Bergsma (1989 developed a semicuantitative system with this purpose, and what is related to the presence and frequency of six microtopography soil surface features after each rain and at the end of tillage: original clods, eroding clods, depressional areas, linear flow pattern of shallow channels and deeper rills, and coverage (vegetation, gravel, etc.; each feature has a length less than 25 cm. The erodability tests demonstrate their practical value with no more than three repetitions per unit of management. There was more soils (8/12 with low erodability. The evolution of microtopograhy soil surface features showed that corn, bean and grass increased depressional areas and shallow channels; the tendency in onion was similar but with a relatibility increase in deeper rills. Bean and grass crops were the less erosion hazard uses because they let a few loss of soil at the more inestable terrains. Contrary, corn and onion are not the most recomendable uses because they allowed the biggest advance of erosion in the most stable soils.

    For two decades now, research and urban practice at Escuela Técnica Superior de Arquitectura de Madrid has notably come apart from dominant planning ideology, in which "urban project" has been considered from a quite reductionist approach, so embedded in the paradigmatic tautology of "urban urbanism", as the only way of working and teaching. In 1977 a group of professors of what latter became the Departamento de Urbanística y Ordenación del Territorio de la E.T.S. de Arquitectura de Madrid decided to organize themselves as a working group with the objective of developing research projects and eventually professional work of particular interest in the fields of city and regional planning. Under the name of Seminario de Planeamiento y Ordenación del Territorio (SPyOT this group started a series of research projects focusing initially in Madrid -as central object of study and laboratory of new planning initiatives- and in the comprehensive plans of the main Spanish cities. After 20 years of uninterrupted activity the initial group has grown and consolidated, and its fields of activity have expanded. More than one hundred projects coordinated by two dozens of professors have been completed in which about 200 hundred students have cooperated. A permanent platform for research within the university has developed and an alternative for professional work for full-time professors has been created, following the guidelines of the University Reform Law (LRU. A considerable number of outstanding students have started careers in the planning field, both in the public and private sectors. After 20 years it can be said that the always difficult relationship between academia and the professional world, both for students and professors, has been facilitated by the existence of the SPyOT. Today the SPyOT has become the Sección de Urbanismo del Instituto Juan de Herrera. This publication includes, after some introductory remarks by the Directors of the Planning Department of the

    The results are documented of jet plume effects wind tunnel test of the 0.020-scale 88-OTS launch configuration space shuttle vehicle model in the 11 x 11 foot leg of the NASA/Ames Research Center Unitary Plan Wind Tunnel. This test involved cold gas main propulsion system (MPS) and solid rocket motor (SRB) plume simulations at Mach numbers from 0.6 to 1.4. Integrated vehicle surface pressure distributions, elevon and rudder hinge moments, and wing and vertical tail root bending and torsional moments due to MPS and SRB plume interactions were determined. Nozzle power conditions were controlled per pretest nozzle calibrations. Model angle of attack was varied from -4 deg to +4 deg; model angle of sideslip was varied from -4 deg to +4 deg. Reynolds number was varied for certain test conditions and configurations, with the nominal freestream total pressure being 14.69 psia. Plotted force and pressure data are presented.

    Aero-loads investigations were conducted on the updated configuration-5 space shuttle launch vehicle at Mach numbers 2.50, 3.50, and 4.50. Six-component vehicle forces and moments, base and sting-cavity pressures, elevon hinge moments, wing-root bending and torsion moments, and normal shear force data were obtained. Full simulation of updated vehicle protuberances and attach hardware was employed. Various elevon deflection angles were tested, with two different forward orbiter-to-external-tank attach-strut configurations. The entire vehicle model 72-OTS was supported by means of a balance mounted in the orbiter through its base and suspended from an appropriate sting for the specific tunnel.

    The authors discuss present-day ideas concerning precursor cells in lymphoid tissues and suggest that the stem cells' decision in regard to proliferation and the path of further differentiation may be a multi-stage process, occurring at various successive phases in the histogenesis of lymphoid cells. They propose that only those elements which are capable of actively deciding (under the influence of suitable stimuli or factors inherent in the cell) in which direction the successor cells are to differentiate should be regarded as precursor cells. It is shown that there are in lymphoid tissue at least three stages with the properties of precursor cells: the stem haemopoietic cell, the antigen-sensitive cell and the immunological memory cell. The authors suggest that the working cells of immune response are transformed into immunological memory cells, and discuss the morphological characteristics of the precursor cells.

    A seminar on radioactive waste treatment and disposal was held 9 - 14 November 1998 in Oskarshamn, Sweden. The objective of the seminar was to exchange information on national and international procedures, practices and requirements for waste management. This information exchange was intended to promote the development of a suitable strategy for management of radioactive waste in Northwest Russia to be used as background for future co-operation in the region. The seminar focused on (1) overviews of international co-operation in the waste management field and national systems for waste management, (2) experiences from treatment of low- and intermediate-level radioactive waste, (3) the process of determining the options for final disposal of radioactive waste, (4) experiences from performance assessments and safety analysis for repositories intended for low- and intermediate level radioactive waste, (5) safety of storage and disposal of high-level waste. The seminar was jointly organised and sponsored by the Swedish Radiation Protection Institute (SSI), the Norwegian Radiation Protection Authority (NRPA), the Nordic Nuclear Safety Research (NKS) and the European Commission. In brief, the main conclusions are: (1) It is the prerogative of the Russian federal Government to devise and implement a waste management strategy without having to pay attention to the recommendations of the meeting, (2) Some participants consider that many points have already been covered in existing governmental documents, (3) Norway and Sweden would like to see a strategic plan in order to identify how and where to co-operate best, (4) There is a rigorous structure of laws in place, based on over-arching environmental laws, (5) Decommissioning of submarines is a long and complicated task, (6) There are funds and a desire for continued Norway/Sweden/Russia co-operation, (7) Good co-operation is already taking place.

    This monograph gives the results of research into the molecular structure of humic acids; certain issues are examined of an applied nature; the data from experimental industrial tests are generalized. Data are generalized which involve questions of the use of humic acids in the form of multiple-ton product. In agriculture, they are used for producing final complex fertilizers and plant growth stimulators; in drilling technology, for improving drilling muds; in the cement industry, for lowering the moisture content of cement raw material sludges. Methods of modifying humates by sulfomethylation are described, and a method for producing coal-alkali reagents directly at drilling and cement firms, based on intensifying the process of interaction of coals with alkali solutions.

    Full Text Available Хронические раневые дефекты (трофические язвы стоп часто встречающееся и специфичное для диабета поражение. Их определяют как эрозию кожи, распространяющуюся не только на эпидермис и дерму, но и проникающую в более глубоко расположенные ткани и характеризующуюся замедленной эпителизацией [13]. Распространенность хронических раневых дефектов нижних конечностей у пациентов с сахарным диабетом, по мнению различных авторов, составляет от 4 до 15% [16]. Локализация поражений на стопе зависит в основном от этиологических факторов. По данным эпидемиологических исследований у больных сахарным диабетом наиболее часто диагностируются раневые дефекты тыльной и подошвенной поверхностей пальцев, подошвенной поверхности в зоне проекции плюснефаланговых суставов и костей предплюсны. Последние характеризуются наиболее тяжелым течением и худшим клиническим прогнозом [14]. Большинство исследователей считает нейропатию, связанные с ней изменения периферической чувствительности и специфические изменения костных структур стопы наиболее значимым фактором в развитии хронических раневых дефектов мягких тканей нижних конечностей. Для того чтобы правильно выбрать тактику лечения хронических раневых дефектов у больных сахарным диабетом, необходимо учитывать особенности течения раневого процесса у данной категории пациентов.

  17. Crystal structure of the regulatory subunit of archaeal initiation factor 2B (aIF2B) from hyperthermophilic archaeon Pyrococcus horikoshii OT3: a proposed structure of the regulatory subcomplex of eukaryotic IF2B

    Eukaryotic translation initiation factor 2B (eIF2B) is the guanine-nucleotide exchange factor for eukaryotic initiation factor 2 (eIF2). eIF2B is a heteropentameric protein composed of α-ε subunits. The α, β, and δ subunits form a regulatory subcomplex, while the γ and ε form a catalytic subcomplex. Archaea possess homologues of α, β, and δ subunits of eIF2B. Here, we report the three-dimensional structure of an archaeal regulatory subunit (aIF2Bα) from the hyperthermophilic archaeon Pyrococcus horikoshii OT3 determined by X-ray crystallography at 2.2 A resolution. aIF2Bα consists of two subdomains, an N-domain (residues 1-95) and a C-domain (residues 96-276), connected by a long α-helix (α5: 78-106). The N-domain contains a five helix bundle structure, while the C-domain folds into the α/β structure, thus showing similarity to D-ribose-5-phosphate isomerase structure. The presence of two molecules in the crystallographic asymmetric unit and the gel filtration analysis suggest a dimeric structure of aIF2Bα in solution, interacting with each other by C-domains. Furthermore, the crystallographic 3-fold symmetry generates a homohexameric structure of aIF2Bα; the interaction is primarily mediated by the long α-helix at the N-domains. This structure suggests an architecture of the three subunits, α, β, and δ, in the regulatory subcomplex within eIF2B

    Occupational therapy relies primarily on communication between the therapist and client for effective intervention. Adequate communication may be influenced by language and cultural differences between the therapist and client. Cultural competence in relation to language and culture is thus a vital part in practice. Limited research exists on cultural competence in occupational therapy students. This study thus aimed to explore the cultural competence of final year students and their perceptions of their own cultural competence, with respect to language and culture in their practice as students. An explorative qualitative study design was utilised with a nonprobability purposeful sample of 21 final year undergraduate students at a tertiary institute in South Africa. Three focus groups were conducted, comprising between 6 and 8 students in each group. Thematic analysis using inductive reasoning was undertaken in order to analyse the students' experiences and understanding of cultural competence. Findings of the study suggest that cultural competence, in relation to language and culture, influences the occupational therapy intervention process. It was shown to both positively and negatively influence intervention through supporting or hindering rapport building, client centeredness, and effective intervention.

    Full Text Available This paper focuses on the impact of certain factors on the contemporary distribution of natural (226Ra, 232Th, 40К and anthropogenic (137Cs, 60Co radionuclides in the sediments of the Baltic Sea. The results of the study suggest that the distribution of 137Cs is determined by the content of hydromica of silty-clay and clay grain-size fractions, while radiocaesium is mainly accumulated by silty fractions. The accumulation of 226Ra by bottom sediments is mainly determined by the pH geochemical barrier at the water-seafloor boundary. The accumulation of 232Th occurs mainly in clayey fractions of the sediment. The distribution and accumulation of 40K is predominantly determined by the ratio of potassium contained in hydromica minerals. Significant 60Co activity was registered only in a few samples.

    In this work the electrostatic properties of poly(3-octylthiophene) thin films have been studied on a nanometer scale by means of electrostatic force microscopy and Kelvin probe microscopy (KPM). The KPM images reveal that different surface contact potential domains coexist on the polymer surface. This result, together with additional capacitance measurements, indicates that the potential domains are related to the existence of dipoles due to different molecular arrangements. Finally, capacitance measurements as a function of the tip-sample bias voltage show that in all regions large band bending effects take place.

  3. Treatability study Number PDC-1-O-T. Final report

    International Nuclear Information System (INIS)

    1998-01-01

    Los Alamos National Laboratory provided treatability study samples from four waste streams, designated Stream number-sign 1, Stream number-sign 3, Stream number-sign 6, and Stream number-sign 7. Stream number-sign 1 consisted of one 55-gallon drum of personal protective equipment (PPE), rags, and neutralizing agent (bicarbonate) generated during the cleanup of a sodium dichromate solution spill. Stream number-sign 3 was one 55-gallon drum of paper, rags, lab utensils, tools, and tape from the decontamination of a glovebox. The sample of Stream number-sign 6 was packaged in three 30-gallon drums and a 100 ft 3 wooden box. It consisted of plastic sheeting, PPE, and paper generated from the cleanup of mock explosive (barium nitrate) from depleted uranium parts. Stream number-sign 7 was scrap metal (copper, stainless and carbon steel joined with silver solder) from the disassembly of gas manifolds. The objective of the treatability study is to determine: (1) whether the Perma-Fix stabilization/solidification process can treat the waste sample to meet Land Disposal Restrictions and the Waste Acceptance Criteria for LANL Technical Area 54, Area G, and (2) optimum loading and resulting weight and volume of finished waste form. The stabilized waste was mixed into grout that had been poured into a lined drum. After each original container of waste was processed, the liner was closed and a new liner was placed in the same drum on top of the previous closed liner. This allowed an overall reduction in waste volume but kept waste segregated to minimize the amount of rework in case analytical results indicated any batch did not meet treatment standards. Samples of treated waste from each waste stream were analyzed by Perma-Fix Analytical Services to get a preliminary approximation of TCLP metals. Splits of these samples were sent to American Environmental Network's mixed waste analytical lab in Cary, NC for confirmation analysis. Results were all below applicable limits

    1976-12-01

    To set up national standard measuring devices for verifying the unit of the quantity 'absorbed dose rate in soft tissue' at different depths for β-radiation, extrapolation chambers have been developed at the PTB and LMRI. They are constructed of nearly tissue equivalent materials and connected to measuring devices of highest metrological quality. A comparison of these standards has been carried out using two β-ray sources of 90 Sr + 90 Y, one from each laboratory. Absorbed dose rates between 0,5 Gy h -1 and 1.3 Gy -1 have been determined. The overall uncertainties of the absorbed dose rates in tissue are 1.8%. The part of the uncertainty due to systematic uncertainties of corrections unique for each laboratory amounts to 0.8% for the LMRI and 0.7% for the PTB. The ratios of the corresponding absorbed dose rates measured at the PTB and at the LMRI differ by 0.2% to 0.7%. On the average, the LMRI values are 0.4% samller than the PTB values. The agreement is felt to be very satisfactory. (orig.) [de

In insurance statistics systematization and processing of aggregate data on the issued policies, premiums and insurance payments are often made with gross errors, because ones don't set the criteria written policies and related payments to the analyzed statistical universe. Besides, it is often not clearly specify the scheme of calculation of aggregate statistical associated with these policies. The study gives a detailed and rigorous presentation as a method of formation of different cohorts data for a specified period of assessment the aggregated characteristics and methods of calculation of interest to insurance of indicators (absolute and relative for these cohorts. The knowledge of these methods is necessary for a correct assessment of insurance premiums and reserves.

    pouvoir absorbant, en tant que fonction de la concentration de l'absorbant, varie d'apres une courbe caracteristique d'un phenomene de saturation et depend du spectre de neutrons. L'auteur formule une hypothese sur l'obtention du pouvoir absorbant maximum grace a la combinaison de plusieurs absorbants. Cette hypothese a ete largement confirmee par des experiences effectuees, dans des reacteurs a neutrons thermiques et intermediaires, sur de nombreuses combinaisons d'absorbants metalliques ou non. (author) [Spanish] En esta memoria se exponen las leyes que rigen las variaciones de las propiedades mecanicas y termofisicas y del poder de absorcion, en funcion de la concentracion del absorbente, en aleaciones destinadas a los reactores de neutrones termicos e intermedios. La conductividad y el coeficiente de dilatacion termica de las aleaciones absorbentes a base de boro y oxidos de las tierras raras se reducen al aumentar dicha concentracion. En el caso de las aleaciones con oxidos de las tierras raras, la variacion del coeficiente de dilatacion es lineal, mientras que para las alea,- ciones de boro esa caracteristica aditiva se altera. Ello se debe a que a temperaturas elevadas se forman fases de boruro con distintas redes cristalinas. En cuanto al poder absorbente, varia segun una curva de saturacion y depende tambien del espectro neutronico. El autor propone una hipotesis para explicar la aparicion de un maximo en la curva del poder absorbente, que atribuye a un fenomeno de interaleacion de los absorbentes. Esta hipotesis ha sido confirmada ampliamente por los resultados de experimentos efectuados con muchos sistemas absorbentes metalicos y no metalicos, de variada composicion, en reactores de neutrones termicos e intermedios.

Во всех случаях диагностировались прогрессирующая стенокардия напряжения или впервые возникшая тяжелая стенокардия III?IV функциональных классов, по явившаяся в предшествующий месяц. Кроме общепринятой терапии НС, пациентам случайным образом выбирали для лечения ?-адреноблокатор карведилол ? до 25?50 мг/сут (1-я группа, n=35 или атенолол ? до 50?100 мг/сут (2-я группа, n=35.

Через полгода лечения карведилолом отмечалось значительное увеличение средней величины фракции выброса ЛЖ на 16,3%. Уменьшение выраженности дилатации полости ЛЖ приводило к увеличению относительной толщины его стенки (на 3,5% и снижению индекса сферичности (на 5,9%.

Карведилол обеспечивал тенденцию к снижению частоты повторных госпитализаций по поводу НС, случаев развития ИМ и наступления смерти по сравнению с атенололом. Однако главным образом из-за в целом небольшого количества наступавших осложнений эти различия не достигали уровня статистической значимости.

    A theoretical and experimental study was made concerning the kinetics of formation of electric moments in solid dielectrics bombarded with fast electrons in the atmosphere. The energy of bombarding electrons in the experiment ranged from 0.6 to 2.0 MeV, at an incident flux density ranging 1.10/sup -9/ to 5.10/sup -7/ A/cm/sup 2/. The specimens were actually grounded during bonbardment, owing to the high electrical conductivity of the ionized ambient gas, and the electric moments were equal to zero. The formation of electric moments occurred after cessation of the bombardment, because the density of the accumulated space charge had become redistributed. An examination was made of the redistribution of space-charge density due to the electrical conductivity of the dielectric, due to intrinsic charge carriers, and due to the release of charges stored in traps. Analytical relations derived for the kinetics of the electric moments give a qualitative description of the experimental results. 5 references.

Experimental data under dependence of G and k values from concentration of iron atoms in beryllium ceramic matrix are presented. It is shown, that structure modification of beryllium ceramics by feedings on the iron base leads to sharp decrease (almost in 30 times) of radiation defects quantum yield value, i.e. to increase of these ceramics stability enhancement to ionizing radiation effect.

    2011-09-01

    We propose to use the unique viewing geometry of the Galactic spiral arm tangents , which provide an ideal environment for studying the effects of density waves on spiral structure. We propose a well-sampled map of the[C II] 1.9 THz line emission along a 15-degree longitude region across the Norma-3kpc arm tangential, which includes the edge of the Perseus Arm. The COBE-FIRAS instrument observed the strongest [C II] and [N II] emission along these spiral arm tangencies.. The Herschel Open Time Key Project Galactic Observations of Terahertz C+ (GOT C+), also detects the strongest [CII] emission near these spiral arm tangential directions in its sparsely sampled HIFI survey of [CII] in the Galactic plane survey. The [C II] 158-micron line is the strongest infrared line emitted by the ISM and is an excellent tracer and probe of both the diffuse gases in the cold neutral medium (CNM) and the warm ionized medium (WIM). Furthermore, as demonstrated in the GOTC+ results, [C II] is an efficient tracer of the dark H2 gas in the ISM that is not traced by CO or HI observations. Thus, taking advantage of the long path lengths through the spiral arm across the tangencies, we can use the [C II] emission to trace and characterize the diffuse atomic and ionized gas as well as the diffuse H2 molecular gas in cloud transitions from HI to H2 and C+ to C and CO, throughout the ISM. The main goal of our proposal is to use the well sampled (at arcmin scale) [C II] to study these gas components of the ISM in the spiral-arm, and inter-arm regions, to constrain models of the spiral structure and to understand the influence of spiral density waves on the Galactic gas and the dynamical interaction between the different components. The proposed HIFI observations will consist of OTF 15 degree longitude scans and one 2-degree latitude scan sampled every 40arcsec across the Norma- 3kpc Perseus Spiral tangency.

    In vitro radiation survival of peripheral blood T lymphocytes was studied in 15 clinically normal adults and 4 patients with Fanconi's anemia. Tritiated thymidine incorporation in a whole blood lymphocyte stimulation test (LST) and a newly developed whole blood T-lymphocyte colony assay were used to measure lymphocyte blastogenesis and colony formation in response to phytohemagglutinin (PHA) or concanavalin-A (Con-A) stimulation. Lymphocyte colony formation was found to be consistently more sensitive than the LST for detection of low-level radiation effects using both normal cells and lymphocytes from Fanconi's anemia patients. Lymphocytes from patients with Fanconi's anemia were significantly more sensitive to in vitro x-irradiation than lymphocytes from clinically normal individuals as measured by their ability to divide when stimulated by PHA in the LST (patients, D37 . 198 R; normals, D37 . 309 R, p . 0.057) and colony formation assay (patients, D37 . 53 R; normals, D37 . 109 R, p . 0.016). No significant difference in the radiosensitivity of the Con-A response was observed between the two groups. The PHA-responsive T-lymphocyte subpopulation in Fanconi's anemia patients appears to be intrinsically defective. The nature of this defect, significance in the disease process, and relevancy of these findings to the establishment of radiation protection standards are discussed

    Claudios Galen (119-199 a.d.) dissected lower animals with parasellar carotid retia bathed in venous blood and transposed his findings to human anatomy. Andreas Vesalius (1514-1564) corrected most of Galen's errors but apparently never looked into this small, extradural compartment, nor, apparently, did Winslow (Exposition Anatomique de la Structure du Corps Humain. London: N. Prevast, 1734), who christened it the "cavernous sinus," (CS) presumably thinking that it would resemble the corpora cavernosa of the penis. Multiple surgical explorations, gross dissections, microscopic views, and vascular casts from early fetuses to an 81 year old have been examined and reviewed. The CS is not a dural sinus nor is it cavernous. The compartment is extradural, and the venous structures contained within consist of a greatly variable plexus of extremely thin-walled veins. The name, CS, is a barrier to the understanding of the structure and function of this extradural anatomical jewel box, which contains fat, myelinated and nonmyelinated nerves, arteries, and a plexus of veins. It is proposed that this name be changed, because it is inaccurate and misleading. The replacement should leave no doubt about its meaning. The lateral sellar compartment is descriptive and accurate. The veins within are a parasellar plexus.

    1994-01-01

    In a research project supported by the Environmental protection Agency (Umweltbundesamt) of the FRG we studied the connection between pesticide utilization and pesticide occurrence in groundwater in 58 examples of waterworks. Two thirds of all water sampling points considered were dominated by groundwater and most of these wells were built in porous aquifers. In other sampling points surface water or water which was dominated by artificial recharge of surfacewater of bankfiltration was analysed for pesticides. Independent of the sampling point character 5% of all single substance tests showed the occurrence of pesticides. Atrazine, desethylatrazine and simazine were detected with a frequency exceeding the average occurrence. The herbicides diuron and bromacil could be measured at least with an average frequency, indicating that the application of both substances in water protection areas may cause water quality problems.

    2017-11-01

    Full Text Available The abrupt transfer of the Casa de la Contratación and the Consulado de Cargadores a Indias from Seville to Cádiz in 1717 opened a political struggle between the two cities that would not be completely resolved until the enlightened absolutism of the Marqués de la Ensenada imposed its will. This struggle witnessed old regime politics at both their best and their worst. The present work seeks to analyze the several manifestations of this competition as well as the broader settings in which they occurred. While the new absolutism first appeared through the abad Alberoni in the original transfer and again through its affirmation by the duque de Ripperdá, with the hand of Queen Isabel not far beneath the surface, the traditional culture of consultation and compromise would eventually emerge and permit Seville to retain important powers until much later. Then, in a new era with much different priorities, which were heavily influenced by the coming of the War of the Asiento, royal absolutism as personified by Ensenada and his immediate predecessors would strip Sevilla of its remaining rights and at long last complete the transfer that had begun over twenty-six years before.

  11. A re-examination of symmetry/Group relationships as applied ot the elementary particles

    International Nuclear Information System (INIS)

    Byrd, K.; Cole R.

    1993-01-01

    The purpose of this investigation is to apply Group Theory to the elementary particles. Group Theory is a mathematical discipline used to predict the existence of elementary particles by physicists. Perhaps, the most famous application of Group Theory to the elementary particles was by Murray Gell-Mann in 1964. Gell-Mann used the theory to predict the existence and characteristics of the then undiscovered Omega Minus Particle. Group Theory relies heavily on symmetry relationships and expresses them in terms of geometry. Existence and the characteristics of a logical intuitable, but unobserved member of a group are given by extrapolation of the geometric relationships and characteristics of the known members of the group. In this study, the Delta, Sigma, Chi and Omega baryons are used to illustrate how physicists apply geometry and symmetrical relationships to predict new particles. The author's hypothesis is that by using the D3 crystal symmetry group and Gell-Mann's baryons, three new particles will be predicted. The results of my new symmetry predicts the Omega 2, Omega 3, and Chi 3. However, the Chi 3 does not have characteristics consistent with those of the other known group members

    1985-11-01

    Intravenous digital subtraction angiography (DSA) was performed in 119 patients with lower extremity ischemia using a 14'' amplifier. Four injections of contrast medium were usually necessary for a complete evaluation of this vascular region. Images of good quality were obtained in most cases; movement artifacts and a faint opacification accounted for any poor results, which occured mainly under the knee. The technique of pixel shifting turned out to be very useful to remove movement artifacts. The 'measuring field' allowed us to minimize the problem of the inhomogeneous saturation of the amplifier. In 8% of the cases an intra-arterial DSA has been performed after an unsatisfactory intravenous examination. Conventional angiography appears to be no longer necessary.

    Lushnikova, A. V.

    In the article material from various cultural and linguistic sources (Indo-European - Slavic, Indo-Iranian; Uralo-Altaic, Tungus, Ancient Egyptian, Babylonian) is used in order to trace up the chronology of the designation of Ursa Majopr, a constellation which has been playing an important role for people different regions since ancient times. It was used for observing of the visible yearly motion of the Sun, for working out seasonal changes; being a circumpolar and non-hiding behind the horizon it has been perceived as a symbol of immortality, its peculiar positional change during a year lay down in plot of the Uralo-Siberian myths about a cosmic hunt for the Elk, myths about deluge. Data from Uralo-Siberian mythology are analyzed. Designations of Ursa Major in the form of a horned hoofed animal such as elk, deer, cow (Uralo-Altaic, Tungus, Slavic, Indo-Iranian languages; Ancient Greece, Crete, Ancient Egypt) and connected with it (or derived from it) denominations and images of "enclosed space" - "vehicle for travelling and carrying goods" (a wagon, a boat) - "instrument for hunting-fishing, a ritual thing" - "household construction" are taken in consideration. The conclusion is made that the transition of the Ursa Major designation from elk to bear could follow the general tendency to shift from so-called matriarchy to patriarchy, to substitute female deities with male ones, which was reflected "in the rise" of the predatory animal cults (not earlier than II mil. B.C.). To prove this, lexical examples of resemblance and coincidences in designation of homed hoofed (elk, deer) and predatory (bear, wolf) animals should be analyzed. Such a goal-directed investigation of the chronology of Ursa Major designations has never been carried out.

  18. OT2_amoor_4: A census of debris disks in nearby young moving groups with Herschel.

    Science.gov (United States)

    Moór, A.

    2011-09-01

    Nearly all young stars harbour circumstellar disks, that serve as the reservoir for mass accretion onto the star, and later become the birthplace of planetary systems. After the disappearance of the gas component from the disk a dusty debris disk is formed that is believed to mark the location of the planetesimal belt as well. For outlining the evolution of such debris disks traditionally open clusters and field stars were studied, however we argue that the recently discovered young moving groups are more suitable objects for such analyses, due to their proximity and good coverage of the first 50 Myr period of the planetary system evolution. In this proposal we request 70/160 um Herschel/PACS photometric observations for so-far unobserved moving group members. These observations will provide a complete coverage of all known members within 80 pc of five nearby young moving groups (beta Pic Moving Group, Tucana-Horologium, Carina, Columba, and Argus), in the A to K spectral range. Based on the new observations we will identify new debris disks, characterize the disk population within individual moving groups, and study disk evolution by comparing the groups of different ages. The results will be used to verify predictions of the self-stirring model of the evolution of planetesimal disks. We will also compare the properties of debris disks in groups of the same age, looking for additional 'environmental' parameters that affect disk structure over a whole moving group. Our study will be a significant contribution to the census of debris disks in young moving groups, increasing the number of observed sources by a factor of 1.5. Since Spitzer could perform only a limited census and the so-far approved Herschel programs added very few additional moving group obervations, our programme is expected to have a high legacy value.

  3. ICT and OTs: a model of information and communication technology acceptance and utilisation by occupational therapists.

    Science.gov (United States)

    Schaper, Louise K; Pervan, Graham P

    2007-06-01

    There is evidence to suggest that health professionals are reluctant to accept and utilise information and communication technologies (ICT) and concern is growing within health informatics research that this is contributing to the lag in adoption and utilisation of ICT across the health sector. Technology acceptance research within the field of information systems has been limited in its application to health and there is a concurrent need to develop and gain empirical support for models of technology acceptance within health and to examine acceptance and utilisation issues amongst health professionals to improve the success of information system implementation in this arena. This paper outlines a project that examines ICT acceptance and utilisation by Australian occupational therapists. It describes the theoretical basis behind the development of a research model and the methodology being employed to empirically validate the model using substantial quantitative, qualitative and longitudinal data. Preliminary results from Phase II of the study are presented. The theoretical significance of this work is that it uses a thoroughly constructed research model, with potentially the largest sample size ever tested, to extend technology acceptance research into the health sector.

  6. OT1_ipascucc_1: Understanding the Origin of Transition Disks via Disk Mass Measurements

    Science.gov (United States)

    Pascucci, I.

    2010-07-01

    Transition disks are a distinguished group of few Myr-old systems caught in the phase of dispersing their inner dust disk. Three different processes have been proposed to explain this inside-out clearing: grain growth, photoevaporation driven by the central star, and dynamical clearing by a forming giant planet. Which of these processes lead to a transition disk? Distinguishing between them requires the combined knowledge of stellar accretion rates and disk masses. We propose here to use 43.8 hours of PACS spectroscopy to detect the [OI] 63 micron emission line from a sample of 21 well-known transition disks with measured mass accretion rates. We will use this line, in combination with ancillary CO millimeter lines, to measure their gas disk mass. Because gas dominates the mass of protoplanetary disks our approach and choice of lines will enable us to trace the bulk of the disk mass that resides beyond tens of AU from young stars. Our program will quadruple the number of transition disks currently observed with Herschel in this setting and for which disk masses can be measured. We will then place the transition and the ~100 classical/non-transition disks of similar age (from the Herschel KP "Gas in Protoplanetary Systems") in the mass accretion rate-disk mass diagram with two main goals: 1) reveal which gaps have been created by grain growth, photoevaporation, or giant planet formation and 2) from the statistics, determine the main disk dispersal mechanism leading to a transition disk.

  7. The Transition from Spacecraft Development Ot Flight Operation: Human Factor Considerations

    Science.gov (United States)

    Basilio, Ralph R.

    2000-01-01

    In the field of aeronautics and astronautics, a paradigm shift has been witnessed by those in academia, research and development, and private industry. Long development life cycles and the budgets to support such programs and projects has given way to aggressive task schedules and leaner resources to draw from all the while challenging assigned individuals to create and produce improved products of processes. however, this "faster, better, cheaper" concept cannot merely be applied to the design, development, and test of complex systems such as earth-orbiting of interplanetary robotic spacecraft. Full advantage is not possible without due consideration and application to mission operations planning and flight operations, Equally as important as the flight system, the mission operations system consisting of qualified personnel, ground hardware and software tools, and verified and validated operational processes, should also be regarded as a complex system requiring personnel to draw upon formal education, training, related experiences, and heuristic reasoning in engineering an effective and efficient system. Unquestionably, qualified personnel are the most important elements of a mission operations system. This paper examines the experiences of the Deep Space I Project, the first in a series of new technology in-flight validation missions sponsored by the United States National Aeronautics and Space Administration (NASA), specifically, in developing a subsystems analysis and technology validation team comprised of former spacecraft development personnel. Human factor considerations are investigated from initial concept/vision formulation; through operational process development; personnel test and training; to initial uplink product development and test support. Emphasis has been placed on challenges and applied or recommended solutions, so as to provide opportunities for future programs and projects to address and disposition potential issues and concerns as early as possible to reap the benefits associated with learning from other's past experiences.

  8. A parametric study ot protease production in batch and fed-batch cultures of Bacillus firmus.

    Science.gov (United States)

    Moon, S H; Parulekar, S J

    1991-03-05

    Proteolytic enzymes produced by Bacillus species find a wide variety of applications in brewing, detergent, food, and leather industries. Owing to significant differences normally observed in culture conditions promoting cell growth and those promoting production of metabolites such as enzymes, for increased efficacy of bioreactor operations it is essential to identify these sets of conditions (including medium formulation). This study is focused on formulation of a semidefined medium that substantially enhances synthesis and secretion of an alkaline protease in batch cultures of Bacillus firmus NRS 783, a known superior producer of this enzyme. The series of experiments conducted to identify culture conditions that lead to improved protease production also enables investigation of the regulatory effects of important culture parameters including pH, dissolved oxygen, and concentrations of nitrogen and phosphorous sources and yeast extract in the medium on cell growth, synthesis and secretion of protease, and production of two major nonbiomass products, viz., acetic acid and ethanol. Cell growth and formation of the three nonbiomass products are hampered significantly under nitrogen, phosphorous, or oxygen limitation, with the cells being unable to grow in an oxygen-free environment. Improvement in protease production is achieved with respect to each culture parameter, leading in the process to 80% enhancement in protease activity over that attained using media reported in the literature. Results of a few fed-batch experiments with constant feed rate, conducted to examine possible enhancement in protease production and to further investigate repression of protease synthesis by excess of the principal carbon and nitrogen sources, are also discussed. The detailed investigation of stimulatory and repressory effects of simple and complex nutrients on protease production and metabolism of Bacillus firmus conducted in this study will provide useful guidelines for design of bioreactors for production of protease and bulk chemicals by this bacterium.

    The radioecological condition of the Devin region situated in the Rodopes mountain (Bulgaria) has been investigated for the period October 1992 - March 1993. It is believed that the Rodopes were more significantly affected by the Chernobyl accident in comparison with other regions of Bulgaria. Some regions near Kozloduy NPP have been chosen for comparing, for which there are more detailed investigations of the anthropogenic radiation effects. Analysis of the background radiation is made, specific soil and water samples are tested. The alterations in the radiation conditions of the Devin region are analysed. Some conclusions and predictions for the trends in further alterations of the background radiation are made. As a result a draft regional program for environment protection reclamation is prepared.

    Glycine (Gly) is incorporated in roughly half of all known peptaibiotic (nonribosomally biosynthesized antibiotic peptides of fungal origin) sequences and is the residue with the greatest conformational flexibility. The conformational space of Aib (α-aminoisobutyric acid) is severely restricted by the second methyl group attached to the Cα atom. Most of the crystal structures containing Aib are N-terminal protected. Deprotection of the N- or C-terminus of peptides may alter the hydrogen-bonding scheme and/or the structure and may facilitate crystallization. The structure reported here for glycyl-α-aminoisobutyrylglycyl-α-aminoisobutyric acid tert-butyl ester, C16H30N4O5, describes the first N-terminal-unprotected (Gly-Aib)n peptide. The achiral peptide could form an intramolecular hydrogen bond between the C=O group of Gly1 and the N-H group of Aib4. This hydrogen bond is found in all tetrapeptides and N-terminal-protected tripeptides containing Aib, apart from one exception. In the present work, this hydrogen bond is not observed (N...O = 5.88 Å). Instead, every molecule is hydrogen bonded to six other symmetry-related molecules with a total of eight hydrogen bonds per molecule. The backbone conformation starts in the right-handed helical region (and the left-handed helical region for the inverted molecule) and reverses the screw sense in the last two residues.

  14. OT1_ebergin_5: A Systematic Survery of the Water D to H Ratio in Hot Molecular Cores

    Bergin, E.

    2010-07-01

    The D/H ratio of water and the enrichment of HDO relative to H2O in comets, oceans, and interstellar water vapor, has been posited as one of the primary links between chemistry in the cold (T = 10-20 K) dense interstellar medium (ISM) and chemistry in the Solar Nebula. However, there are only ~10 measurements of HDO/H2O, even in hot (T > 100 K) molecular cores, which have the most favorable chemistry (due to fossil evaporation of D-enriched ices) and excitation. In addition the existing measurements have a wide range of uncertainty, making it impossible to discern the presence of source-to-source variations, which could hint at the origin of deuterium enrichments in the dense ISM. We propose here to change this statistic with a systematic survey of HDO and H2O in a sample of 20 hot molecular cores spanning a two order of magnitude range in mass and luminosity. This will increase the number of known water D/H ratios by ~200%. This program is unique in scope for Herschel and requires the uniformity in calibration and high spectral resolution offered by the HIFI instrument. With the stability of HIFI we will be able to derive D/H ratios with significantly less uncertainty. Our observations will be combined with theoretical chemical models to explore the statistics offered by this sample. By looking at a large number of objects with a range of conditions we aim to unlock the secrets of water deuteration in the interstellar space.

    Sunburn is the skin's visible reaction to acute overexposure to ultraviolet radiation (UVR). It is estimated that in any given year there are about 3,150 new cases of malignant melanoma, the deadliest kind of skin cancer, and 64,000 new cases of non-melanoma skin cancers in Canada. Between 1986 and 1995 the age-standardized mortality of malignant melanoma increased by an annual average of 2.7 per cent among men and 1.7 per cent among women, the largest increase in mortality of all cancers in men and the second largest among women. This report provides a brief overview of the main characteristics, sources and health effects of ultraviolet radiation, along with a description of general protective measures and recommendations for specific settings. The expectation is that the document will help to promote sound UVR exposure reduction practices, and by so doing, help to reduce the negative health effects of overexposure to UVR among Canadians. The recommended protective measures include minimizing sun exposure (including exposure to sunlamps which are not considered a safe way to get a tan); seeking shade, especially from 11.00 AM to 4.00 PM; covering up; using a sunscreen with SPF 15 or higher that has both UV and UVB protection; and using lip and eye protection. Practising regular skin self-examination is also recommended.

    Highlights: • Determined the structure of UDP-D-ManNAcADH to a resolution of 1.55 Å. • First complex structure of PhUDP-D-ManNAcADH with UDP-D-ManMAcA. • The monomeric structure consists of three distinct domains. • Cys258 acting as catalytic nucleophilic and Lys204 acts as acid/base catalyst. • Oligomeric state plays an important role for the catalytic function. - Abstract: UDP-N-acetyl-D-mannosamine dehydrogenase (UDP-D-ManNAcDH) belongs to UDP-glucose/GDP-mannose dehydrogenase family and catalyzes Uridine-diphospho-N-acetyl-D-mannosamine (UDP-D-ManNAc) to Uridine-diphospho-N-acetyl-D-mannosaminuronic acid (UDP-D-ManNAcA) through twofold oxidation of NAD{sup +}. In order to reveal the structural features of the Pyrococcus horikoshii UDP-D-ManNAcADH, we have determined the crystal structure of the product-bound enzyme by X-ray diffraction to resolution of 1.55 Å. The protomer folds into three distinct domains; nucleotide binding domain (NBD), substrate binding domain (SBD) and oligomerization domain (OD, involved in the dimerization). The clear electron density of the UDP-D-ManNAcA is observed and the residues binding are identified for the first time. Crystal structures reveal a tight dimeric polymer chains with product-bound in all the structures. The catalytic residues Cys258 and Lys204 are conserved. The Cys258 acts as catalytic nucleophile and Lys204 as acid/base catalyst. The product is directly interacts with residues Arg211, Thr249, Arg244, Gly255, Arg289, Lys319 and Arg398. In addition, the structural parameters responsible for thermostability and oligomerization of the three dimensional structure are analyzed.

    The research reported in this paper describes the development, empirical validation and analysis of a model of technology acceptance by Australian occupational therapists. The study described involved the collection of quantitative data through a national survey. The theoretical significance of this work is that it uses a thoroughly constructed research model, with one of the largest sample sizes ever tested (n=1605), to extend technology acceptance research into the health sector. Results provide strong support for the model. This work reveals the complexity of the constructs and relationships that influence technology acceptance and highlights the need to include sociotechnical and system issues in studies of technology acceptance in healthcare to improve information system implementation success in this arena. The results of this study have practical and theoretical implications for health informaticians and researchers in the field of health informatics and information systems, tertiary educators, Commonwealth and State Governments and the allied health professions.

    Full Text Available Resumo Após a pesquisa da Unesco sobre relações raciais no Brasil, Florestan Fernandes organizou e liderou uma jovem equipe para tratar do mesmo tema. A preferência recaiu então sobre os estados da Região Sul do Brasil, que não tinham feito parte da pesquisa original. Escolhidos por Florestan Fernandes, Fernando Henrique Cardoso, Roberto Jardim Moreira e Octávio Ianni fizeram parte dessa equipe. Na distribuição dos estados, coube a Ianni o Paraná e Santa Catarina, esse último conjuntamente com Fernando Henrique. Embora o objetivo da pesquisa fosse demonstrar a existência de preconceito nas relações raciais naqueles estados, Ianni ficou surpreso em descobrir também um novo preconceito, dessa feita contra imigrantes poloneses e seus descendentes, na cidade de Curitiba, capital do Paraná. Ianni investigou inicialmente a questão e publicou alguns artigos a respeito, nos quais tentou explicar o inesperado preconceito. No intuito de dar continuidade e investigar mais a fundo o fenômeno, elaborou e publicou um projeto de pesquisa sobre o tema que, contudo, nunca veio à luz.

    Full Text Available Subject of this article is the copy of Four Gospels preserved at the Church Institute in Sofia (gr. 949, which was displayed in the Brilliance of Byzantium Exhibition organized during the 22nd International Congress of Byzantine Studies (August 22 - 27, 2011 and which we assumed to have been produced by the hand of one of the most famous scribes at the end of the 13th and the beginning of the 14th century, i.e. Theodore Hagiopetrites. The type of the script employed in the Four Gospels at the Church Institute (CHAI gr. 949 is in the so-called by L. Politis unique ‘Hagiopetrites Style’. Although the manuscript does not contain a colophon, comparison to the manuscripts of Theodore Hagiopetrites known to us and especially to Cod. D. gr. 29 (Olim. Kos. 35 at the Ivan Dujčev Centre - an autograph of the scribe of 1307, as well as to another manuscript from Saint Petersburg, Cod. gr. of ASUSSR, No 10/667 of the 14th century, provides good reasons to assume that the Four Gospels manuscript (CHAI gr. 949 was also produced by Theodore Hagiopetrites. Our certainty was further substantiated after we had studied in situ the Four Gospels from Academician N. P. Likhachev’s archive published by Igor Medvedev in the collection ‘ In Memoriam Ivan Dujčev’ of 1988 which is currently kept under No 10/667 in the Archive of the Leningrad Section of the Institute of History at the Russian Academy of Science. Having compared the illumination and the specifics of motif stylization, as well as the specific colouring, we could assert that the two manuscripts manifest pronounced similarities. Thereby, the 27 manuscripts by T. Hagiopetrites published by R. Nelson should also be supplemented by the Four Gospels at the Church Institute (CHAI gr. 949 in addition to the Apostle Lectionary of 1307, autograph of Theodore Hagiopetrites at the Dujčev Centre, Cod. D. gr. 29 (Olim. Kos. 35, which R. Nelson briefly mentioned in his preface, and the Saint Petersburg Four Gospels, published by I. Medvedev.

    The use of ionizing radiation for processing foodstuffs is being studied in the USSR, particularly in connection with the following: (a) prevention of sprouting in potatoes and onions; (b) disinfestation of foodstuffs; (c) suppression of microbe activity; either sterilization or partial inhibition of microflora activity to prolong the shelf life of various foodstuffs; and (d) alterations in the ripening time of fruits and vegetables after picking and/or harvesting. The paper reports the status of work performed in the USSR during recent years on each of these general topics and the prospects for the practical application of irradiation to a number of products are considered. Among the products in question are meat and meat products (raw and cooked semi-finished products, sausage products), domestic poultry, various fruits and vegetables, potatoes, grain, dehydrated products (dried fruits and vegetables, dried food concentrates). Practical methods of irradiating potatoes and onions to prevent sprouting during storage have already been developed, and very soon it will be possible to use radiation for the disinfestation of foodstuffs on an industrial scale.

    The fundamental study of the electrochemical processes of corrosion and inhibition involves various factors, including in particular: (a) adsorption phenomena of different types; (b) ion-exchange properties of passive films; and (c) the electrochemical kinetics of both anodic and cathodic processes across the interface between a metal and its corrosive environment. The availability of radioisotopes has made possible certain studies of these phenomena that could not be made previously with conventional techniques. The element technetium, a homologue of manganese in the periodic system, has been found uniquely suited to certain of these studies by reason of its nuclear properties. The chemical properties of technetium compounds are summarized and contrasted with those of corresponding Cr{sup 51} compounds and those of molybdenum and tungsten, so much used in studies of inhibition. Selected experimental studies are given as examples of the uses to which technetium has already been put in this type of work. Among these are empirical studies of its action as a very efficient inhibitor of the corrosion of iron, together with the results of long-term observations of surface activity. Other studies with both Tc{sup 99} and I{sup 131} have demonstrated the significance of competitive adsorption of ions in the determination of the kinetics of the corrosion and inhibitory processes. Finally, the author shows how the unique properties of technetium have permitted a clear discrimination between the relative contributions of oxygen and the oxidizing inhibitor in the maintenance of passivity. (author) [French] Parmi les facteurs qui entrent en jeu dans l'etude fondamentale des processus electrochimiques de corrosion et d'inhibition on releve notamment: a) differents types de phenomenes d'adsorption; b) les proprietes d'echange ioniques des films passifs; c) la cinetique electrochimique des processus tant anodiques que cathodiques qui se produisent dans l'interface entre un metal et le milieu corrosif. Avec les radioisotopes, on peut maintenant entreprendre sur ce sujet certaines recherches impossibles avec les moyens classiques. Le technetium, homologue du manganese dans la classification periodique, s'est revele l'element de choix pour certaines de ces recherches. Ses proprietes nucleaires sont extremement interessantes a cet egard. Le memoire resume les proprietes chimiques des composes du technetium, qu'il oppose a celles des composes correspondants du chrome-51, ainsi qu'a celles du molybdene et du tungstene, d'usage repande dans les recherches sur l'inhibition. L'auteur decrit ensuite quelques etudes experimentales a titre d'exemples des emplois que le technetium a deja trouves dans les travaux de ce genre. Il mentionne notamment certains etudes empiriques sur l'action du technetium en tant qu'inhibiteur tres efficace de la corrosion du fer, ainsi que les resultats d'observations faites pendant une longue periode sur l'activite de surface. D'autres recherches au moyen du technetium-99 et de l'iode-131 ont montre l'importance de l'adsorption competitive d'ions dans l'etude cinetique des processus de corrosion et d'inhibition. Enfin l'auteur mentre comment les proprietes speciales du technetium ont permis de faire une distinction nette entre la part de l'oxygene et celle de l'inhibiteur oxydant dans le maintien de la passivite. (author) [Spanish] Algunos de los factores que intervienen, en los estudios fundamentales de los procesos electroquimicos de corrosion e inhibicion son los siguientes: a) fenomenos de adsorcion de diversos tipos, b) propiedades de intercambio ionico de las peliculas pasivas, y c) la cinetica electroquimica de los procesos anodicos y catodicos que tienen lugar en la fase que separa un metal del medio corrosivo. Los radioisotopos han hecho posible ciertos estudios de estos fenomenos que antes no podian llevarse a cabo con los metodos clasicos. Se ha comprobado que el tecnecio, tm homologo dol manganeso en el sistema periodico, es particularmente adecuado para algunos de estos estudios. Las ventajas do este elemento estriban, en sus propiedades nucleares. La memoria resume las propiedades quimicas de los compuestos de tecnecio y las compara con las de los compuestos correspondientes de {sup 51}Cr, de molibdeno y de wolframio, que con tanta frecuencia se emplean en el estudio de la inhibicion. La memoria describe seguidamente ciertos estudios experimentales como ejemplo de los usos a que se ha destinado el tecnecio en los trabajos de este tipo. Entre ellos menciona estudios empiricos de su accion como eficaz inhibidor de la corrosion del hierro, y observaciones de la actividad de superficie realizadas durante periodos largos de tiempo. Otros estudios efectuados con {sup 99}Tc y con {sup 131}I han demostrado la importancia de la adsorcion competitiva de iones en la determinacion de la cinetica de los procesos de corrosion y de inhibicion. Como tercer ejemplo, describe como las propiedades excepcionales del tecnecio han permitido distinguir claramente las contribuciones relativas del oxigeno de las del inhibidor oxidante en el mantenimiento de la pasividad.

  9. A new determination of cross sections in methane and silane by using an exact method of solution ot the Boltzmann equation

    International Nuclear Information System (INIS)

    Segur, P.; Balaguer, J.P.

    1984-01-01

    We use a modified form of the SN method to solve the Boltzmann equation. We are then able to take into account the strong anisotropy of the distribution function which is known to occur in methane and silane. For a given set of cross-sections, the swarm parameters calculated with this method are very different from these published by previous authors (obtained with the standard two term Legendre expansion of the distribution function). The cross sections which we deduce by comparing experimental and calculated values for drift velocity and transversal diffusion coefficient are very different from these of Pollock or Duncan and Walker. With these two new sets of cross sections we make some calculations in mixtures of methane and silane, methane and argon, silane and argon. We note that our results for swarm parameters (at low E/N) are in good agreement with experimental values when they are available

In contrast with commercial databases, such as Web of Knowledge and Scopus, which exclude most of the scientific journals published in tropical countries, BINABITROP is a comprehensive record of knowledge on the tropical ecosystems and organisms of Costa Rica. We analyzed its contents in three sites (La Selva, Palo Verde and Las Cruces) and recorded scientific field, taxonomic group and authorship. We found that most records dealt with ecology and systematics, and that most authors published only one article in the study period (1963-2011). Most research was published in four journals: Biotropica, Revista de Biología Tropical/ International Journal of Tropical Biology and Conservation, Zootaxa and Brenesia. This may be the first study of a such a comprehensive database for any case of tropical biology literature.

    Full Text Available BINABITROP is a bibliographical database of more than 38 000 records about the ecosystems and organisms of Costa Rica. In contrast with commercial databases, such as Web of Knowledge and Scopus, which exclude most of the scientific journals published in tropical countries, BINABITROP is a comprehensive record of knowledge on the tropical ecosystems and organisms of Costa Rica. We analyzed its contents in three sites (La Selva, Palo Verde and Las Cruces and recorded scientific field, taxonomic group and authorship. We found that most records dealt with ecology and systematics, and that most authors published only one article in the study period (1963-2011. Most research was published in four journals: Biotropica, Revista de Biología Tropical/ International Journal of Tropical Biology and Conservation, Zootaxa and Brenesia. This may be the first study of a such a comprehensive database for any case of tropical biology literature.BINABITROP es una base de datos bibliográfica con más de 38 000 registros sobre los ecosistemas y organismos de Costa Rica. En contraste con bases de datos comerciales como Web of Knowledge y Scopus, que excluyen a la mayoría de las revistas científicas publicadas en los países tropicales, BINABITROP registra casi por completo la literatura biológica sobre Costa Rica. Analizamos los registros de La Selva, Palo Verde y Las Cruces. Hallamos que la mayoría de los registros corresponden a estudios sobre ecología y sistemática; que la mayoría de los autores sólo registraron un artículo en el período de estudio (1963-2011 y que la mayoría de la investigación formalmente publicada apareció en cuatro revistas: Biotropica, Revista de Biología Tropical/International Journal of Tropical Biology, Zootaxa y Brenesia. Este parece ser el primer estudio de una base de datos integral sobre literatura de biología tropical.

    2011-11-01

    By using line transect method, an investigation was conducted on the floor litter and soil arthropod community in a mid mountain wet evergreen broad-leaved forest, a mossy dwarf forest, and a Populus bonatii forest in Ailao Mountain of Yunnan in April (dry and hot season), June (rainy season), and December (dry and cold season), 2005. In both dry and rainy seasons, the existing floor litter mass, C storage, and C/N ratio in the three forests all increased in the order of mossy dwarf forest > P. bonatii forest > evergreen broad-leaved forest, but the N storage had less difference. In the floor litter layer of the forests, Acari and Collembola were the dominant groups of soil arthropod community, while Diptera larvae, Coleoptera, ants, and Homoptera were the common groups. The Sorenson coefficients of soil arthropod community in the three forests were extremely great. No significant differences were observed in the soil arthropod density (ind x m(-2)) in the floor litter layer among the three forests, but the relative density (ind x g(-1)) of soil arthropods was higher in the evergreen broad-leaved forest and P. bonatii forest than in the mossy dwarf forest. In the three forests, the density of soil arthropods was significantly higher in dry season than in rainy season, but the Shannon diversity index had less difference. There were significant positive correlations between the existing floor litter mass and the individual density (ind x m(-2)) and dominant groups of soil arthropod communities in dry and hot season (April), but negative correlations between the existing floor litter mass and the relative density (ind x g(-1)) of soil arthropod communities and Acari in dry and cold season (December). The individual densities of Collembola and Coleoptera also had positive correlations with the N storage of the existing floor litter mass in the three forests. It was considered that the floor litter and the development of soil arthropod community in the litter layer of the subtropical forests in Ailao Mountain had a close relation with the vegetation structure of the forests, and the individual density and the diversity of the soil arthropod community were controlled by the floor litter, whereas the environmental factors such as temperature and moisture in the forests also had obvious effects on the seasonal dynamics of the individual density of the soil arthropods.

    Full Text Available Lichens are symbiotic associations of fungi with microalgae and/or cyanobacteria. Lichens belonging to the Parmeliaceae family comprise 2700 species of lichens, including the Parmotrema genus which is composed of 300 species. The metabolites of this genus include depsides, depsidones, phenolics, polysaccharides, lipids, diphenylethers and dibenzofurans, which are responsible for the biological activities reported including antidiabetic, antihelmintic, anticancer, antioxidant, antibacterial, anti-inflammatory, antimitotic, antitumoral, antifungal, and antioxidant enzyme inhibitory. Due to scarce knowledge of metabolomic profiles of Parmotrema species (P. andinum and P. robustum, a full metabolome study based on ultra-high performance liquid chromatography- diode array detector-electrospray ionization-quadrupole-orbitrap-mass-spectrometry (UHPLC-DAD-ESI-Q-orbitrap MS was performed for a comprehensive characterization of their substances. From the methanolic extracts of these species, a total of 54 metabolites were identified for the first time using this hyphenated technique, including thirty compounds in P. andinum, and thirty-seven in P. robustum. Moreover, two compounds were not identified as known compounds, and could be new structures, according to our data. This report shows that this technique is effective and accurate for rapid chemical identification of lichen substances and the compounds identified could serve as chemotaxonomic markers to differentiate these ruffle lichens.

  5. Cineradiography of the liquid bolus swallow. A study of the speed ot the bolus and peristaltic wave and of movement of the hyoid bone, larynx, and epiglottis

    In the evaluation of the dysphagic patient, radiology is crucial as a technique for monitoring morphology and function. In particular, high-speed cineradiography can reveal a variety of pharyngeal dysfunctions. However, in the literature and in practice the difference between normal and abnormal function is not always clear. This monography is based on high-speed cineradiographies of swallowing in 75 non-dysphagic volunteers and in 189 dysphagic patients. The purpose was to study whether differences in bolus volumes, patient position, age and gender had any effects on the following parameters: the speed of the peristaltic wave and apex of the liquid barium bolus, the length of movement and the movement pattern of the hyoid bone and larynx, and epiglottic function. The study disclosed that the speed of the bolus, the anterior-superior movement and net movement of the hyoid bone increased significantly with larger bolus volumes. The position of the individual in relation to gravity significantly influenced the speed of peristalsis. In most of the measured parameters there were no differences between non-dysphagic and dysphagic individuals expect for differences in the intrapersonal variations and in the anterior-superior movement of the hyoid bone. In patients with pharyngeal dysfunction the initial stage of the elevation of the larynx was significantly lower than in patients without dysfunction. The approximation of the thyroid cartilage to the hyoid bone was significantly greater in individuals with normal epiglottic function than in those with epiglottic dysmobility. It is suggested that abnormal speed of peristalsis may be a mild form of dysfunction. Measurements of the aforementioned speed and movements can be done if bolus volume, age and position of the patient, film speed and magnifications factors are known. Hypotheses concerning epiglottic function and central control of swallowing are proposed. (au)

    The aim of the study was to assess the cleansing-effect of two endodontic handpieces (Excalibur, W & H; MM 1400 Micro Méga) in root canals that were previously manually prepared, and treated with chlor-(Neomagnol) and citric acid containing solutions. The analyses were performed by scanning electron microscope (SEM). The elimination of the Smear Layer (SL) with Neomagnol was not successful with either of the two handpieces. The cleansing of the Superficial Debris (SD) with Neomagnol activated by MM 1400 was significantly more effective in the apical (p < 0.05) and in the middle (p < 0.01) third of the root-canal, than by Excalibur. In contrast, SL was better eliminated by Excalibur using citric acid, significant differences--when compared with MM 1400--could be seen in the middle third (p < 0.05) of the root-canal. The handpieces seem to have their own specific characteristics: thus MM 1400 was better in eliminating the SD (used with Neomagnol), while Excalibur was superior in eliminating the SL (used with citric acid).

  10. ATTRIBUTION OF CONDUCT TO A STATE-THE SUBJECTIVE ELEMENT OF THE INTERNATIONAL RESPONSIBILITY OT THE STATE FOR INTERNATIONALLY WRONGFUL ACTS

    Directory of Open Access Journals (Sweden)

    FELICIA MAXIM

    2012-05-01

    Full Text Available In order to establish responsibility of states for internationally wrongful act, two elements are identified. First, the conduct in question must be attributable to the State under international law. Secondly, for responsibility to attach to the act of the State, the conduct must constitute a breach of an international legal obligation in force for that State at that time. For particular conduct to be characterized as an internationally wrongful act, it must first be attributable to the State. The State is a real organized entity, a legal person with full authority to act under international law. But to recognize this is not to deny the elementary fact that the State cannot act of itself. States can act only by and through their agents and representatives. In determining what constitutes an organ of a State for the purposes of responsibility, the internal law and practice of each State are of prime importance. The structure of the State and the functions of its organs are not, in general, governed by international law. It is a matter for each State to decide how its administration is to be structured and which functions are to be assumed by government. But while the State remains free to determine its internal structure and functions through its own law and practice, international law has a distinct role. Conduct is thereby attributed to the State as a subject of international law and not as a subject of internal law. The State as a subject of international law is held responsible for the conduct of all the organs, instrumentalities and officials which form part of its organization and act in that capacity, whether or not they have separate legal personality under its internal law.

    Investigated were structural transformations in 0Kh18N10T steel as a result of heating and cooling and of deformation within the range of temperatures between 300 and 77 K, the quantity relationships between the said transformations and the variation of the yield limit with the temperature. The studies were conducted by metallography and mechanical test methods. It was shown that an increase in the number of heating and cooling cycles correlates with a loss in strength of the steel while deformation at 77 K. This anomaly in the temperature relationship of the yield limit is related to the appearance in the course of deformation of α-martensite with a BCC lattice. Deformation at 300 K increases the amount ea of epsilon-martensite, a decrses the effectve size of grain and, in consequence, increases the yield limit. The relationship between the yield limit and the grain size at the temperature of 300 K is described adequately by the Hall-Petch equation

    Full Text Available The paper is a part of the research that focuses on the Catholic theologians and biologists between 1871 and 1910 who accepted Mivart’s thesis of the evolutionary origin of the human body, or who, on the contrary, tended to reject it. The paper presents J. Knabenbauer SJ (1839–1911. In the 1930s, Czech theologian J. Miklik asserted that Knabenauer accepted Mivart’s position. Knabenbauer’s study on evolution is analysed. Already in 1877, Knabenbauer shows, in the first two parts of his work, an openness to the reality of evolutionary origin of species in the fauna and flora. In the third part, he deals with Mivart’s thesis. From the philosophical point of view, Knabenbauer admits the possibility of the creation of human body by way of evolution. From the exegetical point of view, he refuses the reading of Gen 2:7 that considered this verse to be an allusion of the origin of the human body from the animal base. Because of this later view, Miklik’s information is to be considered imprecise. Knnabenbauer’s study contains, though, much relevant information that testifies to the Catholic theology and exegesis of his era.

    Full Text Available This study was designed to investigate the effect of feed form (mesh or pellet and vegetation cover (available or unavailable on the growth performance, some organ weights and carcass characteristics of slow growing broiler chickens reared in the free range system in a 2x2 factorial design. A total of 800, day-old slow-growing broiler chickens (Hubbard Isa Red-JA 87 were randomly allotted into 4 dietary treatments, and 4 replicates of 50 birds. The effect of feed form was much more pronounced than forage intake in terms of body weight gain and feed conversion ratio with significant improvements in favour of pellet feed form. Throughout the experimental periods of 25 to 48 and 49 to 72, chicks fed on pellet feed gained more body weight which accompanied to lower feed conversion ratio compared to those receiving mesh feed. Pellet feed decreased feed consumption of birds from 25 to 48 days as compared to birds fed with mesh feed. However, this tendency disappeared thereafter and no significant difference was found between treatments throughout the experimental periods. Carcass yield of broiler chicks slaughtered at 72 days of age was not significantly affected by either feed form or green grass intake during the outdoor access.

    To evaluate the efficacy and safety of an ultra-low-dose oral contraceptive (NPC-01; 0.02 mg ethinyl estradiol and 1 mg norethisterone) in subjects with dysmenorrhea. Placebo-controlled, double-blind, randomized trial. Clinical trial sites. Two hundred fifteen subjects with dysmenorrhea. Subjects were randomly assigned to receive NPC-01, placebo, or IKH-01 (0.035 mg ethinyl estradiol and 1 mg norethisterone) for four cycles. Total dysmenorrhea score (verbal rating scale) assessing pain on the basis of limited ability to work and need for analgesics. The reductions of total dysmenorrhea score and visual analog scale score after the treatment were significantly higher in the NPC-01 group than in the placebo group. Furthermore, the efficacy of NPC-01 was comparable to that of IKH-01. The overall incidence of side effects was significantly higher in the NPC-01 group than in the placebo group. All side effects that occurred in the NPC-01 group were previously reported in patients receiving IKH-01. No serious side effects occurred. The ultra-low-dose contraceptive NPC-01 relieved dysmenorrhea as effectively as IKH-01. Thus, NPC-01 could represent a new option for long-term treatment of dysmenorrhea. NCT01129102.

  20. Conservation presence, not socioeconomics, leads to differences in pastoralist perceived threats to argali

    Full Text Available Community-based conservation approaches that keep people on landscapes increasingly complement preservationist models of reserves without people. Evaluations of community conservation have shown that economic incentives and socioeconomics primarily drive people’s attitudes and perceptions. Work at Mongolia’s Ikh Nart Nature Reserve demonstrates how to achieve successful conservation by integrating local people into the overall program. Using a short questionnaire, we interviewed pastoralist families across two soums (similar to a U.S. county in Ikh Nart. We examined (1 pastoralists’ perceived threats to argali sheep (Ovis ammon, (2 socioeconomic differences among pastoralists, and (3 differences between pastoralists from different soums. We found that 15 years of conservation activities—education, research, and modest ecotourism—that occurred in the northern soum led to influences on people’s perceptions toward argali conservation. Compared with pastoralists from southern Ikh Nart, pastoralists from the northern part of the reserve more likely knew that argali are protected and understood primary threats to the species. Socioeconomic factors, such as age, sex, and wealth, did not significantly influence responses. The negligible economic incentives in Ikh Nart did not lead to response differences. Our results demonstrate that conservation can influence people across socioeconomic classes without providing large economic incentives.

    Oxytocin (OT) is a neuropeptide elaborated by the hypothalamic paraventricular (PVN) and supraoptic (SON) nuclei. Magnocellular OT neurons of these nuclei innervate numerous forebrain regions and release OT into the blood from the posterior pituitary. The PVN also harbors parvocellular OT cells that project to the brainstem and spinal cord, but their function has not been directly assessed. Here, we identified a subset of approximately 30 parvocellular OT neurons, with collateral projections onto magnocellular OT neurons and neurons of deep layers of the spinal cord. Evoked OT release from these OT neurons suppresses nociception and promotes analgesia in an animal model of inflammatory pain. Our findings identify a new population of OT neurons that modulates nociception in a two tier process: (1) directly by release of OT from axons onto sensory spinal cord neurons and inhibiting their activity and (2) indirectly by stimulating OT release from SON neurons into the periphery.

    Full Text Available The Code 5651 which sets Internet censhorship in Turkey has been active for 3 years. With this lawr, our country twanted to be a leader among democratic countries and challenged giant companies like Youtube and Google and fined them with tax penalty. Our country t is trying to set İnternational Law on Internet via code 5651 and decisions of its courts. But it doesn't do this by defending or negotiating the issue on international forums or United Nations. It considers Internet as media and it punishes and bans similar to printing press.. A serious number of people, including the Prime Minister, break the ban. The President of the Republic, State Minister for EU, Minister of Transportation and chairman of Information and Communication Technologies Authority give statements against these bans. In the meantime, rule of law, separation of powers, fair trial, and basic human rights such as freedom of expression are ignored. In other words, a Legal Tradegy occurs in front of lawyers and intellectuals. And our country commits hara-kiri by not understanding Internet, just like the situation in printing machine. In this article, various dimensions of the 3-year struggle of Turkey with Internet are discussed. Türkiye'de İnternet yasaklarını düzenleyen 5651 numaralı kanun çıkalı 3 yılı aştı. Bu kanunun çıkış sürecinde ve bugüne kadar uygulamasında, ülkemiz bir yandan dünyaya önderlik etmeye çalıştı, bir yandan Youtube/ Google gibi devlere meydan okudu; onlara büyük vergi cezaları kesti. Ülkemiz, kendi internet algılaması ve değerlendirmesini dünyaya empoze etmeye çalışıyor. Böylece, bu konuda, uluslararası hukuku tesis etmeye çalışıyor. Bunu, uluslararası forumlarda, Birleşmiş Milletlerde önererek, savunarak, müzakere ederek yapmıyor. İnterneti, basın gibi algılayarak, basına uygulanan yasaklama alışkanlıkları ile yasaklıyor. Başbakan dahil internet yasaklarını önemli bir çoğunluk deliyor. Bu yasaklara Cumhurbaşkanı, Avrupa Birliği’nden sorumlu Devlet Bakanı, hatta Ulaştırma Bakanı ve BTK (Bilgi Teknolojileri ve İletişim Kurumu Başkanı da karşı beyanlar veriyor. Bu arada Hukuk'un temel ilkeleri, kuvvetler ayrılığı, adil yargılama, özgürlüklerin özüne dokunulmaz ilkesi gözardı ediliyor. Bir başka deyişle, ülkenin hukukçuları ve düşünen insanların gözü önünde bir Hukuk Faciası yaşanıyor. Ve ülkemiz, matbaada olduğu gibi, interneti anlamayarak, harakiri yapıyor Bu yazıda, Türkiye'nin internetle savaşının 3 yıllık macerasının boyutları değerlendirecektir

    Experimental aerodynamic investigations were conducted in the NASA/Langley unitary plan wind tunnel on a sting mounted 0.010-scale outer mold line model of the 140A/B configuration of the Rockwell International Space Shuttle Vehicle. The primary test objectives were to obtain: (1) six component force and moment data for the mated vehicle at subsonic and transonic conditions, (2) effects of configuration build-up, (3) effects of protuberances, ET/orbiter fairings and attach structures, and (4) elevon deflection effects on wing bending moment. Six component aerodynamic force and moment data and base and balance cavity pressures were recorded over Mach numbers of 1.6, 2.0, 2.5, 2.86, 3.9, and 4.63 at a nominal Reynolds number of 20 to the 6th power per foot. Selected configurations were tested at angles of attack and sideslip from -10 deg to +10 deg. For all configurations involving the orbiter, wing bending, and torsion coefficients were measured on the right wing.

    An experimental Aerodynamic and Aero-Acoustic loads data base was obtained at transonic Mach numbers for the Space Shuttle Launch Vehicle configured with the ASRM Solid Rocket Boosters as an increment to the current flight configuration (RSRB). These data were obtained during transonic wind tunnel tests (IA 613A) conducted in the Arnold Engineering Development Center 16-Foot transonic propulsion wind tunnel from March 27, 1991 through April 12, 1991. This test is the first of a series of two tests covering the Mach range from 0.6 to 3.5. Steady state surface static and fluctuating pressure distributions over the Orbiter, External Tank and Solid Rocket Boosters of the Shuttle Integrated Vehicle were measured. Total Orbiter forces, Wing forces and Elevon hinge moments were directly measured as well from force balances. Two configurations of Solid Rocket Boosters were tested, the Redesigned Solid Rocket Booster (RSRB) and the Advanced Solid Rocket Motor (ASRM). The effects of the position (i.e. top, bottom, top and bottom) of the Integrated Electronics Assembly (IEA) box, mounted on the SRB attach ring, were obtained on the ASRM configured model. These data were obtained with and without Solid Plume Simulators which, when used, matched as close as possible the flight derived pressures on the Orbiter and External Tank base. Data were obtained at Mach numbers ranging from 0.6 to 1.55 at a Unit Reynolds Number of 2.5 million per foot through model angles of attack from -8 to +4 degrees at sideslip angles of 0, +4 and -4 degrees.

    Wind tunnel tests were performed to determine pressures, heat transfer rates, and gas recovery temperatures in the base region of a rocket firing model of the space shuttle integrated vehicle during simulated yawed flight conditions. First and second stage flight of the space shuttle were simulated by firing the main engines in conjunction with the SRB rocket motors or only the SSME's into the continuous tunnel airstream. For the correct rocket plume environment, the simulated altitude pressures were halved to maintain the rocket chamber/altitude pressure ratio. Tunnel freestream Mach numbers from 2.2 to 3.5 were simulated over an altitude range of 60 to 130 thousand feet with varying angle of attack, yaw angle, nozzle gimbal angle and SRB chamber pressure. Gas recovery temperature data derived from nine gas temperature probe runs are presented. The model configuration, instrumentation, test procedures, and data reduction are described.

    Narrow resonances of 13 C and 17 O have been studied by a measurement of the total neutron cross sections of carbon and oxygen between 3 and 30 MeV. Employing the improved time-of-flight spectrometer at the Karlsruhe Isochronous Cyclotron and precise calibration methods, resonance cross sections were measured with an energy resolution of 1:2100 at 10 MeV and energy accuracies between 10 -4 and 10 -5 . Resonance analysis of the measured data provided parameters for numerous narrow states of both isospins, T = 1/2 and T = 3/2. These data in conjunction with information from broad T = 1/2 resonances provided a good means to experimentally determine isospin mixing matrix elements. Results were obtained for the first five T = 3/2 resonances in 17 O and the first T = 3/2 resonance in 13 C. The obtained mixing matrix elements are compared with previous experimental results and shell-modell predictions of this quantity. (orig.) [de

    We generalize the orthogonally transitive (OT) G 2 spike solution to the non-OT G 2 case. This is achieved by applying Geroch’s transformation on a Kasner seed. The new solution contains two more parameters than the OT G 2 spike solution. Unlike the OT G 2 spike solution, the new solution always resolves its spike. (fast track communication)

    The neuropeptide oxytocin (OT) has received increased experimental attention for its putative role in both normal social functioning and several psychiatric disorders that are partially characterized by social dysfunction (e.g., autism spectrum disorders: ASD). Many human experimental studies measure circulating plasma levels of OT in order to examine the relationship between the hormone and behavior. Urinary OT (uOT) assays offer a simple, easy, and non-invasive method to measure peripheral hormone levels, but the correspondence between uOT and plasma OT (pOT) levels is unclear. Here, we conducted two within-subjects, double-blind studies exploring changes in uOT and pOT levels following administration of two drugs: MDMA, an oxytocin-releasing drug (Study 1), and intranasal oxytocin (INOT: Study 1 and 2). In Study 1, 14 adult participants (2 females) were each administered either oral 1.5mg/kg MDMA or 40IU INOT across two different study sessions. In Study 2, 10 male participants (adolescents and young adults) diagnosed with ASD received either 40IU INOT or placebo across two different sessions. In both studies, blood and urine samples were collected before and after drug administration at each study session. For Study 1, 10 participants provided valid plasma and urine samples for the MDMA session, and 8 provided valid samples for the INOT session. For Study 2, all 10 participants provided valid samples for both INOT and placebo sessions. Pre- and post-administration levels of pOT and uOT were compared. Additionally, correlations between percent change from baseline uOT and pOT levels were examined. Study 1: Plasma OT and uOT levels significantly increased after administration of MDMA and INOT. Furthermore, uOT levels were positively correlated with pOT levels following administration of MDMA (r=0.57, p=0.042) but not INOT (r=0.51, p=0.097). Study 2: There was a significant increase in uOT levels after administration of INOT, but not after administration of

  6. Effect of oxytocin injection to milching buffaloes on its content & stability in milk

    Full Text Available Background & objectives: Oxytocin (OT injections to milch cattle for milk letdown have become a common practice amongst dairy farmers in India. Although there is no reported evidence, it is widely presumed that long term consumption of such milk leads to adverse health consequences. However, there is no information on the effect of exogenous OT injections on milk OT content and its stability during heating and gastrointestinal digestion. This study was carried out to determine the OT content in milk samples given by buffaloes with and without OT injections and to assess the stability of OT in the milk. Methods: Milk samples from milch buffaloes (Murrah buffalo were collected from local farmers with (n=121 or without (n=120 exogenous OT injections during 3 to 5 months of lactation period. The OT content of milk samples was estimated by competitive enzyme immunoassay (EIA. The thermal and digestive stability of OT was assessed by in silico and in vitro digestion methods. Results: The OT content of the milk samples was similar regardless of OT injections used. Further, OT was found to be stable to heat treatment and gastric pepsin digestion while it was rapidly digested during the simulated intestinal digestion. r0 educed OT was digested by pepsin, implying that internal disulphide bridge of OT rendered the peptide resistant to peptic digestion. On the other hand, phenylmethylsulphonyl fluoride (PMSF, a serine protease inhibitor, abrogated the pancreatin induced digestion of OT. Interpretation & conclusions: These findings suggest that exogenous OT injections do not influence its content in milk. Further, OT present in milk is rapidly degraded during intestinal digestion, ruling out its intestinal absorption and associated adverse health consequences, if any.

    Overtraining syndrome (OTS) is caused by an imbalance between training, nutrition and resting, and leads to decreased performance and fatigue; however, the precise underlying triggers of OTS remain unclear. This study investigated the body composition, metabolism, eating, sleeping patterns and mood states among participants with OTS. Selected participants were divided into OTS-affected athletes (OTS, n = 14), healthy athletes (ATL, n = 25), and healthy non-physically active controls (NCS, n = 12). Compared to ATL, OTS showed decreased sleep quality (p = 0.004); increased duration of work or study (p sleep, and increased cognitive activity are likely OTS triggers. OTS appears to induce dehydration, increase body fat, decrease libido, and worsen mood.

    2014-03-01

    Full Text Available Studies of body volume expansion have indicated that lesions of the anteroventral third ventricle and median eminence block the release of atrial natriuretic peptide (ANP into the circulation. Detailed analysis of the lesions showed that activation of oxytocin (OT-ergic neurons is responsible for ANP release, and it has become clear that activation of neuronal circuitry elicits OT secretion into the circulation, activating atrial OT receptors and ANP release from the heart. Subsequently, we have uncovered the entire functional OT system in the rat and the human heart. An abundance of OT has been observed in the early development of the fetal heart, and the capacity of OT to generate cardiomyocytes (CMs has been demonstrated in various types of stem cells. OT treatment of mesenchymal stem cells stimulates paracrine factors beneficial for cardioprotection. Cardiovascular actions of OT include: i lowering blood pressure, ii negative inotropic and chronotropic effects, iii parasympathetic neuromodulation, iv vasodilatation, v anti-inflammatory activity, vi antioxidant activity, and vii metabolic effects. OT actions are mediated by nitric oxide and ANP. The beneficial actions of OT may include the increase in glucose uptake by CMs and stem cells, reduction in CM hypertrophy, oxidative stress, and mitochondrial protection of several cell types. In experimentally induced myocardial infarction in rats, continuous in vivo OT delivery improves cardiac healing and cardiac work, reduces inflammation, and stimulates angiogenesis. Because OT plays anti-inflammatory and cardioprotective roles and improves vascular and metabolic functions, it demonstrates potential for therapeutic use in various pathologic conditions.

    2015-01-01

    Full Text Available Oxytocin (OT, the main neuropeptide of sociality, is expressed in neurons exclusively localized in the hypothalamus. During the last decade, a plethora of neuroendocrine, metabolic, autonomic and behavioral effects of OT has been reported. In the urgency to find treatments to syndromes as invalidating as autism, many clinical trials have been launched in which OT is administered to patients, including adolescents and children. However, the impact of OT on the developing brain and in particular on the embryonic and early postnatal maturation of OT neurons, has been only poorly investigated. In the present review we summarize available (although limited literature on general features of ontogenetic transformation of the OT system, including determination, migration and differentiation of OT neurons. Next, we discuss trajectories of OT receptors (OTR in perinatal period. Furthermore, we provide evidence that early alterations, from birth, in the central OT system lead to severe neurodevelopmental diseases such as feeding deficit in infancy and severe defects in social behavior in adulthood, as described in Prader-Willi syndrome. Our review intends to propose a hypothesis about developmental dynamics of central OT pathways, which are essential for survival right after birth and for the acquisition of social skills later on. A better understanding of the embryonic and early postnatal maturation of the OT system may lead to better OT-based treatments in Prader-Willi syndrome and autism.

  4. Oxytocin in the prelimbic medial prefrontal cortex reduces anxiety-like behavior in female and male rats.

    Science.gov (United States)

    Sabihi, Sara; Durosko, Nicole E; Dong, Shirley M; Leuner, Benedetta

    2014-07-01

    The neuropeptide oxytocin (OT) is anxiolytic in rodents and humans. However, the specific brain regions where OT acts to regulate anxiety requires further investigation. The medial prefrontal cortex (mPFC) has been shown to play a role in the modulation of anxiety-related behavior. In addition, the mPFC contains OT-sensitive neurons, expresses OT receptors, and receives long range axonal projections from OT-producing neurons in the hypothalamus, suggesting that the mPFC may be a target where OT acts to diminish anxiety. To investigate this possibility, female rats were administered OT bilaterally into the prelimbic (PL) region of the mPFC and anxiety-like behavior assessed. In addition, to determine if the effects of OT on anxiety-like behavior are sex dependent and to evaluate the specificity of OT, male and female anxiety-like behavior was tested following delivery of either OT or the closely related neuropeptide arginine vasopressin (AVP) into the PL mPFC. Finally, the importance of endogenous OT in the regulation of anxiety-like behavior was examined in male and female rats that received PL infusions of an OT receptor antagonist (OTR-A). Overall, even though males and females showed some differences in their baseline levels of anxiety-like behavior, OT in the PL region of the mPFC decreased anxiety regardless of sex. In contrast, neither AVP nor an OTR-A affected anxiety-like behavior in males or females. Together, these findings suggest that although endogenous OT in the PL region of the mPFC does not influence anxiety, the PL mPFC is a site where exogenous OT may act to attenuate anxiety-related behavior independent of sex.

    Oxytocin (OT) is considered to be a stress-buffering hormone, dampening the physiologic effects of stress. However, OT can also be anxiogenic. We examined acute and long-lasting effects of social defeat on OT neurons in male and female California mice. We used immunohistochemistry for OT and c-fos cells to examine OT neuron activity immediately after defeat (n = 6-9) and 2 weeks (n = 6-9) and 10 weeks (n = 4-5) later. We quantified Oxt messenger RNA with quantitative polymerase chain reaction (n = 5-9). Intranasal OT was administered to naïve and stressed mice tested in social interaction and resident-intruder tests (n = 8-14). Acute exposure to a third episode of defeat increased OT/c-fos colocalizations in the paraventricular nucleus of both sexes. In the medioventral bed nucleus of the stria terminalis, defeat increased Oxt messenger RNA, total OT neurons, and OT/c-fos colocalizations in female mice but not male mice. Intranasal OT failed to reverse stress-induced social withdrawal in female mice and reduced social interaction behavior in female mice naïve to defeat. In contrast, intranasal OT increased social interaction in stressed male mice and reduced freezing in the resident-intruder test. Social defeat induces long-lasting increases in OT production and OT/c-fos cells in the medioventral bed nucleus of the stria terminalis of female mice but not male mice. Intranasal OT largely reversed the effects of stress on behavior in male mice, but effects were mixed in female mice. These results suggest that changes in OT-sensitive networks contribute to sex differences in behavioral responses to stress. Copyright © 2015 Society of Biological Psychiatry.

    Occlusal trauma (OT) and smoking are both factors that alter alveolar bone metabolism and therefore could synergistically act on alveolar bone loss. The aim of this experimental study was to evaluate the influence of short-term cigarette smoke inhalation (CSI) on inter-radicular alveolar bone loss promoted by primary OT in a rat model. Forty-eight animals were randomly assigned to one of three groups based on treatment type: OT + CSI (n = 16), animals were exposed to CSI three times per day, for 8 min per exposure, and they concomitantly received unilateral vertical augmentation creating an occlusal interference inducing experimental OT; OT (n = 16), animals received only unilateral vertical augmentation; negative control (NC; n = 16), animals maintained for equal periods to achieve periodontal baseline values of periodontal ligament dimension. Each group was divided into two subgroups (n = 8) based on treatment length: 7 or 14 d. After 7 d, the OT + CSI group exhibited significantly higher bone loss compared to the NC group (p = 0.0022). After 14 d, the OT (p < 0.0001) and OT + CSI (p < 0.0001) groups presented significantly higher bone loss compared to the NC group, and OT + CSI resulted in significantly higher bone loss than OT alone (p = 0.0241). The number of tartrate-resistant acid phosphatase-positive cells on the linear surface of the bone crest after 7 d was significantly higher in the OT + CSI group as compared to the NC and OT groups (p < 0.0001 and p = 0.0045, respectively) and remained significantly higher in the OT + CSI group after 14 d, compared to the OT group (p < 0.0001). Short-term CSI increases early bone loss in association with OT after 7 d, and this worsens in severity after 14 d of exposure. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  7. Association of Oxytocin and Parental Prefrontal Activation during Reunion with Infant: A Functional Near-Infrared Spectroscopy Study

    2017-12-01

    Full Text Available Although previous studies have revealed the role of oxytocin (OT in parental behavior, the role of OT has not been investigated through the direct assessment of prefrontal brain activation during parenting. By using functional near-infrared spectroscopy, we aimed to show the relationship between parental [maternal (N = 15 and paternal (N = 21] OT levels and the activation of the prefrontal cortex (PFC, while holding their infants after separation. Baseline OT levels were measured in the subjects’ saliva samples before the experiment. Prefrontal brain activation was assessed in participants sitting alone on a chair (i.e., separation from their infant for 120 s and during the target period (i.e., holding their infant for 45 s, which was done in triplicate. The oxygen hemoglobin (oxy-Hb dissociation curve significantly increased in 9 out of 22 channels on the PFC when maternal and paternal samples were combined. However, only the fathers showed a correlation between salivary OT and oxy-Hb signal. Furthermore, while holding their infants, high-OT fathers showed left hemispheric dominance compared to low-OT fathers, while high-OT mothers showed right hemispheric dominance compared to low-OT mothers. This study showed that fathers with high-OT levels showed neural activation with left hemispheric dominance, while holding their infants, suggesting that increase of OT level might activate paternal PFC related to parenting behavior, although the same is not true for mothers.

    The onset of acute myocardial ischemia (MI) is accompanied by a rapid increase in electrical instability and often fatal ventricular arrhythmias. This study investigated that whether oxytocin (OT) can modulate ischemia-induced arrhythmias and considered relationships between the severity of arrhythmia and the electrocardiogram parameters during ischemia. OT (0.0001-1 μg) was administrated intraperitoneally 30 min before ischemia. To examine receptor involved, a selective OT-receptor antagonist, atosiban (ATO), was infused 10 min before OT. OT caused a significant and biphasic dose-dependent reduction in ectopic heart activity and arrhythmia score. OT doses that reduced ventricular arrhythmia elicited significant increase in QT interval. OT attenuated the electrophysiological changes associated with MI and there was significant direct relationship between QRS duration and arrhythmia score. ATO treatment reduced beneficial effects of OT on arrhythmogenesis. Nevertheless, ATO failed to alter OT effects on premature ventricular contractions. We assume that the ability of OT to modulate the electrical activity of the heart may play an important role in the antiarrhythmic actions of OT.

    The aim of the present study was to highlight the newly discovered metabolic role of oxytocin (OT) in the type I diabetic rats. Previous studies have demonstrated that OT has a beneficial role on bone physiology and therefore, the OT effect on the diabetic osteopathy will be assessed as well. Induction of the type I diabetes was carried out by an intraperitoneal injection of 60 mg/kg body weight of streptozotocin. The metabolic role of OT on diabetic rats after OT treatment with intramuscular injection of 40 µIU/kg body weight for 6 weeks was assessed. Histological and ultrastructural studies of rat pancreas samples, before and after the OT injection, were performed and compared with the obtained physiological results. Oxytocin treatment had positive metabolic effects in diabetic rats. This is based on the change in glucose metabolism, lipid profile, and insulin sensitivity in experimental animals. In addition, OT treatment showed histological regenerative changes of pancreatic islet cells of diabetic rats. Moreover, OT administration showed that it has an anabolic effect on the bone biology. The results suggest that activation of the oxytocin receptor (OTR) pathway by infusion of OT, OT analogs, or OT agonists may represent a promising approach for the treatment of diabetes and some of its complications, including diabetic osteopathy.

  11. CSF and blood oxytocin concentration changes following intranasal delivery in macaque.

    Directory of Open Access Journals (Sweden)

    Olga Dal Monte

    Full Text Available Oxytocin (OT in the central nervous system (CNS influences social cognition and behavior, making it a candidate for treating clinical disorders such as schizophrenia and autism. Intranasal administration has been proposed as a possible route of delivery to the CNS for molecules like OT. While intranasal administration of OT influences social cognition and behavior, it is not well established whether this is an effective means for delivering OT to CNS targets. We administered OT or its vehicle (saline to 15 primates (Macaca mulatta, using either intranasal spray or a nebulizer, and measured OT concentration changes in the cerebral spinal fluid (CSF and in blood. All subjects received both delivery methods and both drug conditions. Baseline samples of blood and CSF were taken immediately before drug administration. Blood was collected every 10 minutes after administration for 40 minutes and CSF was collected once post-delivery, at the 40 minutes time point. We found that intranasal administration of exogenous OT increased concentrations in both CSF and plasma compared to saline. Both delivery methods resulted in similar elevations of OT concentration in CSF, while the changes in plasma OT concentration were greater after nasal spray compared to nebulizer. In conclusion our study provides evidence that both nebulizer and nasal spray OT administration can elevate CSF OT levels.

  12. Oxytocin and vasopressin flatten dominance hierarchy and enhance behavioral synchrony in part via anterior cingulate cortex.

    Science.gov (United States)

    Jiang, Yaoguang; Platt, Michael L

    2018-05-29

    The neuropeptides oxytocin (OT) and arginine vasopressin (AVP) influence social functions in many mammals. In humans and rhesus macaques, OT delivered intranasally can promote prosocial behavior in certain contexts. Yet the precise neural mechanisms mediating these behavioral effects remain unclear. Here we show that treating a group of male macaque monkeys intranasally with aerosolized OT relaxes their spontaneous social interactions with other monkeys. OT reduces differences in social behavior between dominant and subordinate monkeys, thereby flattening the status hierarchy. OT also increases behavioral synchrony within a pair. Intranasal delivery of aerosolized AVP reproduces the effects of OT with greater efficacy. Remarkably, all behavioral effects are replicated when OT or AVP is injected focally into the anterior cingulate gyrus (ACCg), a brain area linked to empathy and other-regarding behavior. ACCg lacks OT receptors but is rich in AVP receptors, suggesting exogenous OT may shape social behavior, in part, via nonspecific binding. Notably, OT and AVP alter behaviors of both the treated monkey and his untreated partner, consistent with enhanced feedback through reciprocal social interactions. These findings bear important implications for use of OT in both basic research and as a therapy for social impairments in neurodevelopmental disorders.

    Full Text Available Abstract: Overshooting convective cloud Top (OT-accompanied clouds can cause severe weather conditions, such as lightning, strong winds, and heavy rainfall. The distribution and behavior of OTs can affect regional and global climate systems. In this paper, we propose a new approach for OT detection by using machine learning methods with multiple infrared images and their derived features. Himawari-8 satellite images were used as the main input data, and binary detection (OT or nonOT with class probability was the output of the machine learning models. Three machine learning techniques—random forest (RF, extremely randomized trees (ERT, and logistic regression (LR—were used to develop OT classification models to distinguish OT from non-OT. The hindcast validation over the Southeast Asia and West Pacific regions showed that RF performed best, resulting in a mean probabilities of detection (POD of 77.06% and a mean false alarm ratio (FAR of 36.13%. Brightness temperature at 11.2 μm (Tb11 and its standard deviation (STD in a 3 × 3 window size were identified as the most contributing variables for discriminating OT and nonOT classes. The proposed machine learning-based OT detection algorithms produced promising results comparable to or even better than the existing approaches, which are the infrared window (IRW-texture and water vapor (WV minus IRW brightness temperature difference (BTD methods.

    The use of intranasal oxytocin (OT) in research has become increasingly important over the past decade. Although researchers have acknowledged a need for further investigation of the physiological effects of intranasal administration, few studies have actually done so. In the present double-blind cross-over study we investigated the longevity of a single 24 IU dose of intranasal OT measured in saliva in 40 healthy adult males. Salivary OT concentrations were significantly higher in the OT condition, compared to placebo. This significant difference lasted until the end of testing, approximately 108 minutes after administration, and peaked at 30 minutes. Results showed significant individual differences in response to intranasal OT administration. To our knowledge this is the largest and first all-male within-subjects design study to demonstrate the impact of intranasal OT on salivary OT concentrations. The results are consistent with previous research in suggesting that salivary OT is a valid matrix for OT measurement. The results also suggest that the post-administration 'wait-time' prior to starting experimental tasks could be reduced to 30 minutes, from the 45 minutes typically used, thereby enabling testing during peak OT concentrations. Further research is needed to ascertain whether OT concentrations after intranasal administration follow similar patterns in females, and different age groups.

  16. Oxytocin--its role in male reproduction and new potential therapeutic uses.

    Oxytocin (OT) is traditionally thought of as a "female" neurohypophysis hormone due to its role in parturition and milk ejection. However, OT is recognized as having endocrine and paracrine roles in male reproduction. At ejaculation, a burst of OT is released from the neurohypophysis into the systemic circulation and stimulates contractions of the reproductive tract aiding sperm release. There is conclusive evidence that OT is synthesized within the mammalian testis, epididymis and prostate and the presence of OT receptors (OTRs) through the reproductive tract supports a local action for this peptide. OT has a paracrine role in stimulating contractility of the seminiferous tubules, epididymis and the prostate gland. Interestingly, OT has also been shown to modulate androgen levels in these tissues via stimulation of the conversion of testosterone to dihydrotestostone (DHT) by 5alpha-reductase. The elucidation of OT's role in male reproduction has suggested a number of potential therapeutic uses for this hormone. Exogenous administration of OT has, in some cases, been shown to increase the numbers of ejaculated sperm, possibly by stimulating contractions of the reproductive tract and thus aiding sperm passage. Within the prostate, OT has been shown to affect gland growth both directly and via its interaction with androgen metabolism. Prostate pathologies due to unregulated cell proliferation/growth, such as benign prostatic hyperplasia and cancer, are unfortunately very common and few effective treatments are available. Greater understanding of paracrine growth mediators, such as OT, is likely to provide new mechanisms for treating such pathologies.

  17. Role of oxytocin in improving the welfare of farm animals - A review.

    Recently, increasing attention has been paid to the welfare of farm animals, which have been evaluated using behavioral and physiological measures. However, so far, the measures have almost always been used to estimate poor welfare. In this review, firstly we focus on how oxytocin (OT) relates to positive social behavior, pleasure, and stress tolerance, and second on which management factors stimulate OT release. OT induces maternal and affiliative behaviors and has an anti-stress effect. Further, OT is produced during enjoyable events, and has positive feedback on its own release as well. Therefore, to some extent, the relationship of OT to positive normal behavior was mutually beneficial-heightened OT concentration owing to comfortable rearing conditions induces positive social behavior, which in turn may increase OT concentration. Hence, studies on animal welfare should pay more attention to increasing comfort and the stress tolerance, rather than only focusing on when stress occurs in farm animals.

  18. Vasopressin and Oxytocin Reduce Food Sharing Behavior in Male, but Not Female Marmosets in Family Groups

    2017-07-01

    Full Text Available Oxytocin (OT is critical for lactation and maternal care, but OT and the related nonapeptide vasopressin are important for caregiving behaviors in fathers and alloparents as well. This experiment tested the effects of vasopressin and OT on food sharing in marmoset families. We treated caregivers (parents, siblings with intranasal vasopressin, OT, or saline, and then paired them with the youngest marmoset in the family. Caregivers were given preferred food, and then observed for food sharing and aggressive behavior with young marmosets. OT reduced food sharing from male alloparents to youngest siblings, and fathers that received vasopressin refused to share food with their youngest offspring more often than when treated with OT. Vasopressin increased aggressive vocalizations directed toward potential food recipients in all classes of caregivers. These results indicate that vasopressin and OT do not always enhance prosocial behavior: modulation of food sharing depends on both sex and parental status.

    The ventral occipitotemporal sulcus (vOT) sustains strong interactions with the inferior frontal cortex during word processing. Consequently, activation in both regions co-lateralize towards the same hemisphere in healthy subjects. Because the determinants of lateralisation differ across posterior, middle and anterior vOT subregions, we investigated whether lateralisation in different inferior frontal regions would co-vary with lateralisation in the three different vOT subregions. A whole brain analysis found that, during semantic decisions on written words, laterality covaried in (1) posterior vOT and the precentral gyrus; (2) middle vOT and the pars opercularis, pars triangularis, and supramarginal gyrus; and (3) anterior vOT and the pars orbitalis, middle frontal gyrus and thalamus. These findings increase the spatial resolution of our understanding of how vOT interacts with other brain areas during semantic categorisation on words. PMID:23728081

  20. Central oxytocin and food intake: focus on macronutrient-driven reward

    2015-04-01

    Full Text Available Centrally acting oxytocin (OT is known to terminate food consumption in response to excessive stomach distension, increase in salt loading and presence of toxins. Hypothalamic-hindbrain OT pathways facilitate these aspects of OT-induced hypophagia. However, recent discoveries have implicated OT in modifications of feeding via reward circuits: OT has been found to differentially affect consumption of individual macronutrients in choice and no-choice paradigms. In this mini-review, we focus on presenting and interpreting evidence that defines OT as a key component of mechanisms that reduce eating for pleasure and shape macronutrient preferences. We also provide remarks on challenges in integrating the knowledge on physiological and pathophysiological states in which both OT activity and macronutrient preferences are affected.

    Full Text Available Organotin compounds (OTs have been used as biocides in antifouling paints and agriculture. The IMO introduced a global ban on the use of OTs in antifouling systems in 2001 due to their high toxicity. However, OTs have still been detected in the environment and pose a threat to the ecosystem. Several research groups have summarized the analytical methods, environmental fate, biochemistry, reproductive toxicity and mechanisms of actions of OTs. Here, we reviewed the developmental toxicity of OTs in various organisms such as sea urchin, ascidian, mussel and fish. The differences in sensitivity to OT exposure exist not only in different species but also at different stages in the same species. Though some hypotheses have been proposed to explain the developmental toxicity of OTs, the solid evidences are greatly in need.

    Oxytocin (OT) and vasopressin (AVP) are important hypothalamic neuropeptides that regulate peripheral physiology, and have emerged as important modulators of brain function, particularly in the social realm. OT structure and the genes that ultimately determine structure are highly conserved among diverse eutherian mammals, but recent discoveries have identified surprising variability in OT and peptide structure in New World monkeys (NWM), with five new OT variants identified to date. This review explores these new findings in light of comparative OT/AVP ligand evolution, documents coevolutionary changes in the oxytocin and vasopressin receptors (OTR and V1aR), and highlights the distribution of neuropeptidergic neurons and receptors in the primate brain. Finally, the behavioral consequences of OT and AVP in regulating NWM sociality are summarized, demonstrating important neuromodulatory effects of these compounds and OT ligand-specific influences in certain social domains.

    The role of the neuropeptide oxytocin (OT) ranges from the modulation of neuroendocrine physiological effects to the establishment of complex social and bonding behaviours. Experimental studies in animals, as well as case reports in humans, suggest that OT affects different aspects of sexual behaviour and has predominantly facilitating properties for sexual appetence and performance. Using a previously established experimental paradigm of sexual arousal and masturbation-induced orgasm, this study investigated the acute effects of intranasal OT application (24I.U.) on endocrine parameters and measures of sexual appetence and function in healthy men (n=10). In a double-blind, placebo-controlled, balanced cross-over design, sexual arousal, and orgasm were induced by an erotic film and masturbation. In addition to the continuous recording of endocrine (OT, cortisol, prolactin, epinephrine, norepinephrine) and cardiovascular data (heart rate), parameters of appetitive, consummatory, and refractory sexual behaviour were assessed using the acute sexual experience scale (ASES). OT plasma levels were significantly elevated after intranasal OT throughout the whole experiment (>60 min). In addition, OT treatment induced significantly higher increases in epinephrine plasma levels during sexual activity without affecting cortisol levels, prolactin levels or heart rate. OT treatment did not alter appetitive, consummatory, and refractory sexual behaviour according to the ASES. However, when subjects were asked about their subjective perception of whether OT or placebo had been applied, eight out of 10 subjects in the OT group answered correctly, thus pointing to an altered perception of arousal. In conclusion, intranasally administered OT leads to a marked increase in OT plasma levels together with increased secretion of catecholamines when subjects are engaged in sexual activity in a laboratory setting. As the effects of OT on sexual behaviour were equivocal, future studies

  4. Distinct BOLD activation profiles following central and peripheral oxytocin administration in awake rats

    2015-09-01

    Full Text Available A growing body of literature has suggested that intranasal oxytocin (OT or other systemic routes of administration can alter prosocial behavior, presumably by directly activating OT sensitive neural circuits in the brain. Yet there is no clear evidence that OT given peripherally can cross the blood-brain-barrier at levels sufficient to engage the OT receptor. To address this issue we examined changes in blood oxygen level dependent (BOLD signal intensity in response to peripheral OT injections (0.1, 0.5 or 2.5 mg/kg during functional magnetic resonance (fMRI in awake rats imaged at 7.0 tesla. These data were compared to OT (1ug/5 µl given directly to the brain via the lateral cerebroventricle. Using a 3D annotated MRI atlas of the rat brain segmented into 171 brain areas and computational analysis we reconstructed the distributed integrated neural circuits identified with BOLD fMRI following central and peripheral OT. Both routes of administration caused significant changes in BOLD signal within the first 10 min of administration. As expected, central OT activated a majority of brain areas known to express a high density of OT receptors e.g., lateral septum, subiculum, shell of the accumbens, bed nucleus of the stria terminalis. This profile of activation was not matched by peripheral OT. The change in BOLD signal to peripheral OT did not show any discernible dose-response. Interestingly, peripheral OT affected all subdivisions of the olfactory bulb, in addition to the cerebellum and several brainstem areas relevant to the autonomic nervous system, including the solitary tract nucleus. The results from this imaging study do not support a direct central action of peripheral OT on the brain. Instead, the patterns of brain activity suggest that peripheral OT may interact at the level of the olfactory bulb and through sensory afferents from the autonomic nervous system to influence brain activity.

    Recent studies have shown a higher rate of surgical site infections in hip prosthesis implantation using unidirectional airflow ventilation compared with turbulent ventilation. However, these studies did not measure the air microbial quality of operating theatres (OTs), and assumed it to be compliant with the recommended standards for this ventilation technique. To evaluate airborne microbial contamination in OTs during hip and knee replacement surgery, and compare the findings with values recommended for joint replacement surgery. Air samplings were performed in 28 OTs supplied with unidirectional, turbulent and mixed airflow ventilation. Samples were collected using passive sampling to determine the index of microbial air contamination (IMA). Active sampling was also performed in some of the OTs. The average number of people in the OT and the number of door openings during the sampling period were recorded. In total, 1228 elective prosthesis procedures (60.1% hip and 39.9% knee) were included in this study. Of passive samplings performed during surgical activity in unidirectional airflow ventilation OTs (U-OTs) and mixed airflow OTs (M-OTs), 58.9% and 87.6% had IMA values >2, respectively. Of samplings performed during surgical activity in turbulent airflow OTs (T-OTs) and in turbulent airflow OTs with the surgical team wearing Steri-Shield Turbo Helmets (TH-OTs), 8.6% and 60% had IMA values ≤ 2, respectively. Positive correlation was found between IMA values and the number of people in the OT and the number of door openings (P systems always provide acceptable airborne bacterial counts.

    Background and Purpose There is current interest in oxytocin (OT) as a possible therapeutic in psychiatric disorders. However, the usefulness of OT may be constrained by peripheral autonomic effects, which may involve an action at both OT and vasopressin V1A receptors. Here, we characterized the cardiovascular and thermoregulatory effects of OT, vasopressin (AVP) and the non-peptide OT receptor agonist WAY 267,464 in rats, and assessed the relative involvement of the OT and V1A receptors in these effects. Experimental Approach Biotelemetry in freely moving male Wistar rats was used to examine body temperature and heart rate after OT (0.01 – 1 mg kg−1; i.p.), AVP (0.001 – 0.1 mg kg−1; i.p.) or WAY 267,464 (10 and 100 mg kg−1; i.p.). The actions of the OT receptor antagonist Compound 25 (C25, 5 and 10 mg kg−1) and V1A receptor antagonist SR49059 (1 and 10 mg kg−1) were studied, as well as possible V1A receptor antagonist effects of WAY 267,464. Key Results OT and AVP dose-dependently reduced body temperature and heart rate. WAY 267,464 had similar, but more modest, effects. SR49059, but not C25, prevented the hypothermia and bradycardia induced by OT and AVP. WAY 267,464 (100 mg·kg−1) prevented the effects of OT, and to some extent AVP. Conclusions and Implications Peripherally administered OT and AVP have profound cardiovascular and thermoregulatory effects that appear to principally involve the V1A receptor rather than the OT receptor. Additionally, WAY 267,464 is not a simple OT receptor agonist, as it has functionally relevant V1A antagonist actions. PMID:24641248

    Full text: Changing of character of acts of terrorism in the end of 20 and the beginning of 21 centuries specifies the increased interest of the terrorist organizations to the weapons of mass destruction. The most accessible are the biological and chemical weapons, as well as the self-made {sup d}irty{sup e}xplosive devices filled with a radioactive material. Application by terrorists of the nuclear weapon at the present is not actual. A nuclear ammunition is under the intensive control not only of the state-possessor of the nuclear weapon, but also all world community. Benefit of use of mass destruction weapons by the terrorist organizations is depended of accessibility of combat chemical or biological substances, easiness of their manufacture, a small amount of poisoning and biological substances necessary for use in the closed space, availability of influence on the big areas, psychological pressure upon the world community. The most known incidents related with use of chemical or biological substances were: - 1992 (chemical) - neo nazis attacked synagogue using cyanide, Germany - 1993 (chemical) - cyanide inside the bomb exploded in the World Trade Center, USA - 1994 (chemical) - use of sarin in Matsumoto, Japan led to the death of 8 and hospitalization of 200 people - 1995 (chemical) - again sarin used in Tokyo metro, 12 people died and 5 500 injured - 1995 (chemical) - FBI agents prevented the attack with the use of sarin of Disney land - 1995 (chemical) - attack in Japan with use of cyanide, phosgene and pepper gas - 1995 (biological) - a member of 'Aryan nation' was arrested for ordering a pestilence virus. - 1995 (radiological) - a terrorist organization of Chechnya republic placed a 14 kilo pack filled with a radioactive cesium-137 and explosives in a Moscow park - 1997 (chemical) - 2 attacks of the trading centers with a use of chlor bombs in Japan. The facts mentioned above put before the Republic of Tajikistan objectives of organization of actions for population and territory protection from mass-destruction weapon. Organization of actions on population and territory protection is caused on geographical location of Tajikistan. There is a number of some states near Tajikistan that have nuclear weapon: India, China, Pakistan. The basic actions for protection of the population and territories from weapons of mass destruction are: maintenance and accumulation of means of an individual defense, creation of stocks; creation and restoration of protective constructions of a civil defense; evacuation actions planning; restoration of system of monitoring and the laboratory control of a civil defense of Republic Tajikistan; according to the Government Regulation N 527 and dated on 31{sup st} of October, 2008 the 'Emergency situations and civil defense system development 2009-2014' Program was adopted. According to the Plan of the events within this Programme Committee of emergency situations and civil defense under the Government of Republic of Tajikistan provides a stage-by-stage realization of the actions for protection of population and territories from mass-destruction weapon. One of the important actions is provision and accumulation of the means of personal protection, keeping of this means. The means of personal protections are laboratory tested by the specialists of the Committee of emergency situations and civil defense. Analytical data of the Committee of emergency situations and civil defense allows making some conclusions concerning experienced storage of the means of personal protection. A general analysis of laboratory test indicates that: laboratory tests of filtering boxes indicate the preservation of air flow resistance and waterproof due to the adherence to the rules of keeping; laboratory tests of the front parts of the gas masks and their hardness and waterproof, and the waterproof of the valves show that the front part is dependent on meteorological character of the region of storage at long-term keeping. Conclusions: According to the experience, personal protection equipment kept due to the rules of storage can keep its technical characteristics.

    This work deals in particular with the synthesis and the characterization of the apatitic oxy-silico-phosphates. In a first part is studied the quaternary system: CaO-La 2 O 3 -SiO 2 P 2 O 5 in order to determine the range in which the pure phospho-silicated apatites exist. Then, the obtained phases have been identified and characterized by chemical analysis methods, electron microprobe analysis, X-ray diffraction, infrared and Raman spectroscopies. The study of the uranium solubilization and diffusion in apatitic matrices has been carried out from the determination of the substitution limit, of the oxidation degree and of the diffusion coefficient of uranium in a phospho-silicated apatite. In a second part, the luminescence properties of the Eu 3+ and Ce 3+ ions in phospho-silicated apatites have been studied. This work allows to have a wider vision of the oxy-silico-phosphated apatites and of their synthesis conditions. The study of the physical and chemical properties of britholites doped with actinides or lanthanides ions will be useful to the study of the optical properties of these matrices. (O.M.)

    Isotope-dilution methods have been developed to identify and estimate the small amount of products formed when carbohydrates are irradiated in aqueous solution with Co{sup 60} gamma-radiation. Conventional analytical methods proved inadequate. After irradiation of C{sup 14}-sugar solutions, the autoradiographs prepared after paper chromatography indicated extensive degradation. Using a reverse isotope-dilution procedure involving the addition of known carriers, and conversion of the fragments into crystalline derivatives, various constituents were quantitatively determined. It is possible to distinguish between d- and Z-isomers, and estimate each isomer independently. The method is applicable to other analytical problems in carbohydrate chemistry. A new method for scanning and recording the radioactivity along paper-chromatogram strips, which involves an inexpensive modification to conventional counting equipment, is described. (author) [French] On a mis au point des methodes de dilution isotopique destinees a identifier et a doser les menues quantites de produits qui se forment lorsque des hydrates de carbone en solution aqueuse sont irradies par les rayons gamma du cobalt-60. A cet egard, les methodes d'analyse classiques se sont revelees inadequates. Apres irradiation de solutions de sucre marque au carbone-14, les autoradiogrammes etablis a la suite d'une chromatographic sur papier indiquaient une forte degradation. En recourant a une methode de dilution isotopique inverse, avec adjonction d'entraineurs connus, et en operant une conversion des fragments en derives cristallins, on a pu determiner quantitativement plusieurs elements constitutifs. Il est possible de distinguer les isomeres dextrogyres des isomeres levogyres et de doser chaque isomere independamment. La methode peut etre appliquee a d'autres problemes d'analyse dans la chimie des hydrates de carbone.

Las autorradiografias de cromatogramas sobre papel, obtenidos despues de irradiar soluciones de azucares marcados con {sup 14}C, revelan una considerable degradacion molecular.

    Full Text Available The paper provides a review of the content and structure of the dictionary of Russian unofficial oikonymy published by Maria Akhmetova. The reviewer points out the author’s ability to make a high-quality presentation of a large number of lexical units: more than 2 200 names and non-standard abbreviations for more than 800 settlements of Russia and neighbouring countries. The material was retrieved from a wide array of sources which include both traditional written texts (toponymic and regional dictionaries, dictionaries of slang, scholarly, journalistic and literary texts and relatively new practices of contemporary Internet communications (blogs, Internet forums, social networks, etc. The reviewer emphasizes the correct and adequate manner of lexicographic processing of unofficial settlement names, as well as the author’s theoretical reasoning on their functional specificity. A particular attention is paid to the ideas articulated in the introduction to the dictionary in which the author attempts to define the status of unofficial oikonyms within the toponymic system of a language, qualifying such names as a particular case of toponymic variability, the latter being the basis of a systemicfunctional approach to the interpretation of unofficial names. The reviewer concludes that Maria Akhmetova’s dictionary enlarges our view of sociolinguistic parameters of the functioning of unofficial oikonyms, which is reflected in an extremely detailed system of labels referring to hitchhikers’ slang, military and naval jargon, obsolete vocabulary, journalistic discourse, nonce words, and others. The dictionary contains rich data that can be used in lexicological, morphological, onomastic, sociolinguistic, anthropological research, but also in studies of urban folklore and urban everyday life.

  12. Oxytocin and Estrogen Receptor β in the Brain: An Overview.

    2015-01-01

    Oxytocin (OT) is a neuropeptide synthesized primarily by neurons of the paraventricular and supraoptic nuclei of the hypothalamus. These neurons have axons that project into the posterior pituitary and release OT into the bloodstream to promote labor and lactation; however, OT neurons also project to other brain areas where it plays a role in numerous brain functions. OT binds to the widely expressed OT receptor (OTR), and, in doing so, it regulates homeostatic processes, social recognition, and fear conditioning. In addition to these functions, OT decreases neuroendocrine stress signaling and anxiety-related and depression-like behaviors. Steroid hormones differentially modulate stress responses and alter OTR expression. In particular, estrogen receptor β activation has been found to both reduce anxiety-related behaviors and increase OT peptide transcription, suggesting a role for OT in this estrogen receptor β-mediated anxiolytic effect. Further research is needed to identify modulators of OT signaling and the pathways utilized and to elucidate molecular mechanisms controlling OT expression to allow better therapeutic manipulations of this system in patient populations.

  13. Organotin Exposure and Vertebrate Reproduction: A Review

    Full Text Available Organotin (OTs compounds are organometallic compounds that are widely used in industry, such as in the manufacture of plastics, pesticides, paints, and others. OTs are released into the environment by anthropogenic actions, leading to contact with aquatic and terrestrial organisms that occur in animal feeding. Although OTs are degraded environmentally, reports have shown the effects of this contamination over the years because it can affect organisms of different trophic levels. OTs act as endocrine-disrupting chemicals (EDCs, which can lead to several abnormalities in organisms. In male animals, OTs decrease the weights of the testis and epididymis and reduce the spermatid count, among other dysfunctions. In female animals, OTs alter the weights of the ovaries and uteri and induce damage to the ovaries. In addition, OTs prevent fetal implantation and reduce mammalian pregnancy rates. OTs cross the placental barrier and accumulate in the placental and fetal tissues. Exposure to OTs in utero leads to the accumulation of lipid droplets in the Sertoli cells and gonocytes of male offspring in addition to inducing early puberty in females. In both genders, this damage is associated with the imbalance of sex hormones and the modulation of the hypothalamic–pituitary–gonadal axis. Here, we report that OTs act as reproductive disruptors in vertebrate studies; among the compounds are tetrabutyltin, tributyltin chloride, tributyltin acetate, triphenyltin chloride, triphenyltin hydroxide, dibutyltin chloride, dibutyltin dichloride, diphenyltin dichloride, monobutyltin, and azocyclotin.

    Plasma oxytocin (OT) concentrations were measured by radioimmunoassay (RIA) method without extracting plasma in 11 normal menstruating women. Mean plasma OT level began to increase steadily from the 7th day of the menstrual cycle and this level rose up to 20+-5 μU/ml (Mean+-S.E.) on the 10th day of the cycle. OT level declined to 13+-6 μU/ml on the day of the LH peak and continuously declined for another 2 days - then rose. The OT level was higher during the follicular phase than during the luteal phase. In 1 individual OT measured in 2 cycles a year apart showed the highest level of OT coincided with LH and FSH peak and abruptly declined. When there was the highest level of progesterone, the OT level was measurable 1 out of 11 cycles. From this study, we conclude that OT may have a role in human ovulation either synergistically or alone with other ovulatory mechanisms and ovarian estradiol and progesterone control the secretion of OT and also suggests that OT may play some role in the regulation of the luteolysis and the menstrual cycle in women.

    Many patients with disability require orthodontic treatment (OT) to achieve adequate oral function and aesthetic appearance. The cooperation of disabled patients and of their parents is central to the success of OT, as treatment can involve ethical dilemmas. The aim of this study was to analyze the motivation, expectations and overall satisfaction with OT among parents of patients with disabilities. The parents of 60 disabled Spanish children with physical, mental and/or sensory impairment undergoing OT were surveyed on attitudes to OT and level of satisfaction with the outcomes. The survey consisted of 23 questions in 4 sections: attitude and adaptation, benefits, adverse effects, and level of satisfaction after completion of OT. A control group formed of the parents of 60 healthy children undergoing OT at the same institution were also surveyed. Parents of disabled children undergoing OT showed a high level of motivation and they are willing to collaborate in oral hygiene procedures. Adaptation to the removable appliances was poorer in disabled children but adaptation to fixed appliances was excellent. OT can provide a marked improvement in quality of life, social relationships and oral functionality in disabled children. Among parents of disabled children undergoing OT, the perceived level of overall satisfaction was very high and expectations were often exceeded.

    Conditioned same-sex partner preference can develop in male rats that undergo cohabitation under the effects of quinpirole (QNP, D2 agonist). Herein, we assessed the development of conditioned same-sex social/sexual preference in males that received either nothing, saline, QNP, oxytocin (OT), or QNP+OT during cohabitation with another male (+) or single-caged (-). This resulted in the following groups: (1) Intact-, (2) Saline+, (3) QNP-, (4) OT-, (5) QNP+, (6) OT+ and (7) QNP/OT+. Cohabitation occurred during 24h in a clean cage with a male partner that bore almond scent on the back as conditioned stimulus. This was repeated every 4 days for a total of three trials. Social and sexual preference were assessed four days after the last conditioning trial in a drug-free test in which experimental males chose between the scented familiar male and a novel sexually receptive female. Results showed that males from groups Intact-, Saline+, QNP- and OT- displayed a clear preference for the female (opposite-sex), whereas groups QNP+, OT+ and QNP/OT+ displayed socio/sexual preference for the male partner (same-sex). In Experiment 2, the brains were processed for Nissl dye and the area size of two sexually dimorphic nuclei (SDN-POA and SON) was compared between groups. Males from groups OT-, OT+ and QNP/OT+ expressed a smaller SDN-POA and groups QNP+ and QNP/OT+ expressed a larger SON. Accordingly, conditioned same-sex social/sexual partner preference can develop during cohabitation under enhanced D2 or OT activity but such preference does not depend on the area size of those sexually dimorphic nuclei.

    Orthostatic Tremor (OT) is a movement disorder characterized by a sensation of unsteadiness and tremors in the 13-18 Hz range present upon standing. The pathophysiology of OT is not well understood but there is a relationship between the sensation of instability and leg tremors. Despite the sensation of unsteadiness, OT patients do not fall often and balance in OT has not been formally assessed. We present a prospective blinded study comparing balance assessment in patients with OT versus healthy controls. We prospectively enrolled 34 surface Electromyography (EMG)-confirmed primary OT subjects and 21 healthy controls. Participants underwent evaluations of balance by blinded physical therapists (PT) with standardized, validated, commonly used balance scales and tasks. OT subjects were mostly female (30/34, 88%) and controls were majority males (13/20, 65%). The average age of OT subjects was 68.5 years (range 54-87) and for controls was 69.4 (range 32-86). The average duration of OT symptoms was 18 years. OT subjects did significantly worse on all the balance scales and on most balance tasks including Berg Balance Scale, Functional Gait Assessment, Dynamic Gait Index, Unipedal Stance Test, Functional Reach Test and pull test. Gait speed and five times sit to stand were normal in OT. Common validated balance scales are significantly abnormal in primary OT. Despite the objective finding of impaired balance, OT patients do not commonly have falls. The reported sensation of unsteadiness in this patient population seems to be out of proportion to the number of actual falls. Further studies are needed to determine which components of commonly used balance scales are affected by a sensation of unsteadiness and fear of falling. Copyright © 2017 Elsevier Ltd.

    Full Text Available Abstract Background Previous studies have demonstrated that neonatal manipulation of oxytocin (OT has effects on the expression of estrogen receptor α (ERα and the central production of oxytocin observed in juveniles (at weaning, 21 days of age. The goal of this study was to determine whether the effects of neonatal manipulation of OT last into adulthood, and if the effects differ from those observed during the early postnatal period. On the first day of life, prairie voles (Microtus ochrogaster received one of three doses of OT (High, 3 μg; Med, 0.3 μg; Low, 0.03 μg, an OT antagonist, or isotonic saline. Another group was handled, but not injected. Then as adults, brains were collected, sectioned, and stained for ERα or OT using immunocytochemistry. Results In females, treatment with OT increased the expression of ERα immunoreactivity in the ventral lateral septum (0.03 μg and the ventromedial nucleus of the hypothalamus and central amygdala (0.3 μg. In males, OT antagonist increased ERα expression in the bed nucleus of the stria terminalis. There was no apparent effect of OT on the number of cells producing OT in the paraventricular nucleus of the hypothalamus. Conclusion The current results suggest that neonatal manipulation of OT has long-term organizational effects on the expression of ERα in both males and females. The lack of effect on OT neurons in the paraventricular nucleus suggests that some developmental effects of OT previously observed in weanlings do not persist into adulthood. Developmental effects of OT on ERα patterns were sexually dimorphic, dose-dependent, and site-specific.

  1. AFM investigation of effect of absorbed water layer structure on growth mechanism of octadecyltrichlorosilane self-assembled monolayer on oxidized silicon

    2016-01-01

    The growth mechanism of an octadecyltrichlorosilane (OTS) self-assembled monolayer on a silicon oxide surface at various relative humidities has been investigated. Atomic force microscopy images show that excess water may actually hinder the nucleation and growth of OTS islands. A moderate amount of water is favorable for the nucleation and growth of OTS islands in the initial stage; however, the completion of the monolayer is very slow in the final stage. The growth of OTS islands on a low-water-content surface maintains a relatively constant speed and requires the least amount of time. The mobility of water molecules is thought to play an important role in the OTS monolayers, and a low-mobility water layer provides a steady condition for OTS monolayer growth.

    Early life stress (ELS) has been found to be associated with lower concentrations of plasma oxytocin (OT) in adulthood. It is not yet clear, however, what mechanisms underlie this association. The goal of the present study was to test the role of emotional suppression as an intervening variable between ELS in childhood and plasma OT. In a nonclinical sample of 90 men, ELS, emotional suppression, and plasma OT were assessed. Emotional suppression was positively associated with ELS (r = 0.37, p emotion regulation strategy - was not correlated with ELS or plasma OT concentrations. Cross-sectional regression analyses revealed that the ELS explained variance in plasma OT via emotional suppression. Moderation analyses revealed that the combination of high ELS and high emotional suppression was associated with the lowest concentrations of plasma oxytocin. These findings are consistent with the view that emotional suppression may be one pathway linking ELS and OT.

    Full Text Available As discussed in the larger review in this special issue (MacDonald and Feifel, intranasal oxytocin (IN OT is demonstrating a growing potential as a therapeutic agent in psychiatry. Importantly, research suggests that a variety of individual factors may influence a person’s response to OT. In this mini-review, I provides a review of three: (1 sex and hormonal status; (2 genetic variation in aspects of the OT system (i.e. OT receptors; and (3 attachment history. Each of these factors will be important to monitor as we strive to develop a richer understanding of OT's role in human development, brain-based disease, and the potential for individualized, OT-targeted treatments.

    A radioimmunoassay (RIA) for oxytocin (OT) in urine is described. 125 I-OT was prepared, and antibodies were raised in rabbits against OT coupled to bovine serumalbumine. This allowed us to set up a RIA for OT which limit of detection is 1.25 pg/tube (0.6 μU). The use of an extraction procedure using CG 50 Amberlite is essential. The recovery after extraction reaches 70.5 %. pH 5 is the optimum pH were urine samples must be stored. The superposition of the elution peak of endogenous OT on that of exogenous hormone is an argument in favour of the validity of such an extraction procedure. Daily urinary excretion of OT reaches 9.58 mU +- 3.48 in 18 healthy young men [fr

  5. An Early Postnatal Oxytocin Treatment Prevents Social and Learning Deficits in Adult Mice Deficient for Magel2, a Gene Involved in Prader-Willi Syndrome and Autism.

    Mutations of MAGEL2 have been reported in patients presenting with autism, and loss of MAGEL2 is also associated with Prader-Willi syndrome, a neurodevelopmental genetic disorder. This study aimed to determine the behavioral phenotype of Magel2-deficient adult mice, to characterize the central oxytocin (OT) system of these mutant mice, and to test the curative effect of a peripheral OT treatment just after birth. We assessed the social and cognitive behavior of Magel2-deficient mice, analyzed the OT system of mutant mice treated or not by a postnatal administration of OT, and determined the effect of this treatment on the brain. Magel2 inactivation induces a deficit in social recognition and social interaction and a reduced learning ability in adult male mice. In these mice, we reveal anatomical and functional modifications of the OT system and show that these defects change from birth to adulthood. Daily administration of OT in the first postnatal week was sufficient to prevent deficits in social behavior and learning abilities in adult mutant male mice. We show that this OT treatment partly restores a normal OT system. Thus, we report that an alteration of the OT system around birth has long-term consequences on behavior and on cognition. Importantly, an acute OT treatment of Magel2-deficient pups has a curative effect. Our study reveals that OT plays a crucial role in setting social behaviors during a period just after birth. An early OT treatment in this critical period could be a novel therapeutic approach for the treatment of neurodevelopmental disorders such as Prader-Willi syndrome and autism.

    The establishment and maintenance of stable, long-term male-female relationships, or pair-bonds, are marked by high levels of mutual attraction, selective preference for the partner, and high rates of sociosexual behavior. Central oxytocin (OT) affects social preference and partner-directed social behavior in rodents, but the role of this neuropeptide has yet to be studied in heterosexual primate relationships. The present study evaluated whether the OT system plays a role in the dynamics of social behavior and partner preference during the first 3 weeks of cohabitation in male and female marmosets, Callithrix penicillata. OT activity was stimulated by intranasal administration of OT, and inhibited by oral administration of a non-peptide OT-receptor antagonist (L-368,899; Merck). Social behavior throughout the pairing varied as a function of OT treatment. Compared to controls, marmosets initiated huddling with their social partner more often after OT treatments but reduced proximity and huddling after OT antagonist treatments. OT antagonist treatment also eliminated food sharing between partners. During the 24-h preference test, all marmosets interacted more with an opposite-sex stranger than with the partner. By the third-week preference test, marmosets interacted with the partner and stranger equally with the exception that intranasal-OT treatments facilitated initial partner-seeking behavior over initial contact with the stranger. Our findings demonstrate that pharmacological manipulations of OT activity alter partner-directed social behavior during pair interactions, suggesting that central OT may facilitate the process of pair-bond formation and social relationships in marmoset monkeys.

    The neuropeptide oxytocin (OT) promotes social behavior and attenuates stress responsivity in mammals. Recent clinical evidence suggests OT concentrations may be dysregulated in major depression. This study extends previous research by testing whether: 1) OT concentrations vary systematically in depressive disorders with and without hypercortisolemia, 2) gender differences in OT concentrations are observed in depressed vs. healthy control participants, and 3) OT concentrations are predictive of clinical phenotypes. Plasma OT concentrations of psychotic major depressive (PMD; n = 14: 10 female, 4 male), non-psychotic major depressive (NPMD; n = 17: 12 female, 5 male), and non-depressed, healthy control (n = 19: 11 female, 8 male) participants were assayed at 2000, 2400, 0400, and 0800 h. Plasma cortisol concentrations were quantified at 2300 h, and clinical phenotypes were determined. As expected, PMD participants, compared to NPMD and healthy control participants, showed higher plasma cortisol concentrations. Although both depressed groups showed similar OT concentrations, a significant interaction effect between group and gender was observed. Specifically, depressed females exhibited lower mean OT concentrations than depressed males. Further, depressed vs. healthy control female participants exhibited lower mean OT concentrations, whereas depressed vs. healthy control male participants showed a trend in the opposite direction. OT concentrations were also predictive of desirability, drug dependence, and compulsivity scores as measured by the Million Clinical Multiaxial Inventory-III. All findings were independent of cortisol. These data suggest that OT signaling may provide a mechanism by which to better understand female-biased risk to develop depressive disorders and that plasma OT concentrations may be a useful biomarker of certain clinical phenotypes.

  10. Oxytocin mechanisms of stress response and aggression in a territorial finch.

    All jawed vertebrates produce a form of oxytocin (OT), and in birds, mammals and fish, OT is strongly associated with affiliation. However, remarkably few data are available on the roles of OT and OT receptors (OTRs) in aggression. Because OT and OTRs exert anxiolytic effects in mammals (although context-specific) and modulate stress coping, we hypothesized that OTR activation is at least permissive for territorial aggression. Indeed, we find that peripheral injections of an OTR antagonist significantly reduce male-male and female-female aggression in a highly territorial finch. This finding suggests the hypothesis that aggression is accompanied by an increase in transcriptional (Fos) activity of OT neurons, but contrary to this hypothesis, we find that dominant male residents do not elevate OT-Fos colocalization following an aggressive encounter and that OT-Fos colocalization in the preoptic area and hypothalamus correlates negatively with aggression. Furthermore, OT-Fos colocalization increases dramatically in males that were aggressively subjugated or pursued by a human hand, likely reflecting OT modulation of stress response. Because OT inhibits the hypothalamo-pituitary-adrenal axis, the antagonist effects may reflect the fact that aggressive birds and mammals tend to be hyporesponsive to stress. If this is correct, then 1) the observed effects of OTR antagonism may reflect alterations in corticosterone feedback to the brain rather than centrally mediated OTR effects, and 2) the negative correlation between OT-Fos colocalization and aggression may reflect the fact that more aggressive, stress hyporesponsive males require less inhibition of the hypothalamo-pituitary-adrenal axis than do less aggressive males, despite the requirement of that inhibition for the normal display of aggression.

    Despite the promise of intranasal oxytocin (OT) for modulating social behavior, recent work has provided mixed results. This may relate to suboptimal drug deposition achieved with conventional nasal sprays, inter-individual differences in nasal physiology and a poor understanding of how intranasal OT is delivered to the brain in humans. Delivering OT using a novel 'Breath Powered' nasal device previously shown to enhance deposition in intranasal sites targeted for nose-to-brain transport, we evaluated dose-dependent effects on social cognition, compared response with intravenous (IV) administration of OT, and assessed nasal cavity dimensions using acoustic rhinometry. We adopted a randomized, double-blind, double-dummy, crossover design, with 16 healthy male adults completing four single-dose treatments (intranasal 8 IU (international units) or 24 IU OT, 1 IU OT IV and placebo). The primary outcome was social cognition measured by emotional ratings of facial images. Secondary outcomes included the pharmacokinetics of OT, vasopressin and cortisol in blood and the association between nasal cavity dimensions and emotional ratings. Despite the fact that all the treatments produced similar plasma OT increases compared with placebo, there was a main effect of treatment on anger ratings of emotionally ambiguous faces. Pairwise comparisons revealed decreased ratings after 8 IU OT in comparison to both placebo and 24 IU OT. In addition, there was an inverse relationship between nasal valve dimensions and anger ratings of ambiguous faces after 8-IU OT treatment. These findings provide support for a direct nose-to-brain effect, independent of blood absorption, of low-dose OT delivered from a Breath Powered device.

  14. Influence of oxytocin on emotion recognition from body language: A randomized placebo-controlled trial.

    2016-10-01

    The neuropeptide 'oxytocin' (OT) is known to play a pivotal role in a variety of complex social behaviors by promoting a prosocial attitude and interpersonal bonding. One mechanism by which OT is hypothesized to promote prosocial behavior is by enhancing the processing of socially relevant information from the environment. With the present study, we explored to what extent OT can alter the 'reading' of emotional body language as presented by impoverished biological motion point light displays (PLDs). To do so, a double-blind between-subjects randomized placebo-controlled trial was conducted, assessing performance on a bodily emotion recognition task in healthy adult males before and after a single-dose of intranasal OT (24 IU). Overall, a single-dose of OT administration had a significant effect of medium size on emotion recognition from body language. OT-induced improvements in emotion recognition were not differentially modulated by the emotional valence of the presented stimuli (positive versus negative) and also, the overall tendency to label an observed emotional state as 'happy' (positive) or 'angry' (negative) was not modified by the administration of OT. Albeit moderate, the present findings of OT-induced improvements in bodily emotion recognition from whole-body PLD provide further support for a link between OT and the processing of socio-communicative cues originating from the body of others.

    Sex differences in the oxytocin (OT) system in the brain may explain why OT often regulates social behaviors in sex-specific ways. However, a link between sex differences in the OT system and sex-specific regulation of social behavior has not been tested. Here, we determined whether sex differences in the OT receptor (OTR) or in OT release in the posterior bed nucleus of the stria terminalis (pBNST) mediates sex-specific regulation of social recognition in rats. We recently showed that, compared to female rats, male rats have a three-fold higher OTR binding density in the pBNST, a sexually dimorphic area implicated in the regulation of social behaviors. We now demonstrate that OTR antagonist (5 ng/0.5 μl/side) administration into the pBNST impairs social recognition in both sexes, while OT (100 pg/0.5 μl/side) administration into the pBNST prolongs the duration of social recognition in males only. These effects seem specific to social recognition, as neither treatment altered total social investigation time in either sex. Moreover, baseline OT release in the pBNST, as measured with in vivo microdialysis, did not differ between the sexes. However, males showed higher OT release in the pBNST during social recognition compared to females. These findings suggest a sex-specific role of the OT system in the pBNST in the regulation of social recognition. PMID:26630388

    The aim of the present investigations was to examine the effects of melatonin (Mel) on oxytocin (OT) release under conditions of osmotic stimulation, brought about by hypertonic saline administration, as well as to determine whether osmotically stimulated OT release in Mel-treated Syrian hamster is associated with alterations in the release of prolactin (PRL) and in norepinephrine (NE) and dopamine (DA) content in the hypothalamus. In both Mel- and vehicle-treated hamsters, injection of hypertonic saline was followed by a significant decrease in OT content in the pituitary neurointermediate lobe (NIL) and elevation of plasma OT and PRL levels. Melatonin injections had no significant affect on NIL OT content in either isotonic- or hypertonic-saline treated animals. Pretreatment with Mel did not alter plasma OT or PRL levels in isotonic saline-injected animals. However, Mel facilitated the release of OT, but prevented the release of PRL after hypertonic saline administration. Melatonin treatment reduced hypothalamic NE content (but not that of DA) in isotonic-saline treated animals. After osmotic stimulation, hypothalamic content of NE and DA was significantly lower in Mel-treated than in vehicle-treated animals. Data from the present study suggest that the osmotically-stimulated release of OT and PRL seems to be related to the activation of noradrenergic rather than dopaminergic transmission. Both dopaminergic and noradrenergic transmission may be, however, involved in mediating the effects of Mel on the osmotically-activated OT and PRL release. (author). 48 refs, 3 figs.

    Full Text Available Rodents show robust behavioral responses to odors, including strong preferences or aversions for certain odors. The neural mechanisms underlying the effects of odors on these behaviors in animals are not well understood. Here, we provide an initial proof-of-concept study into the role of the olfactory tubercle (OT, a structure with known anatomical connectivity with both brain reward and olfactory structures, in regulating odor-motivated behaviors. We implanted c57bl/6 male mice with an ipsilateral bipolar electrode into the OT to administer electric current and thereby yield gross activation of the OT. We confirmed that electrical stimulation of the OT was rewarding, with mice frequently self-administering stimulation on a fixed ratio schedule. In a separate experiment, mice were presented with either fox urine or peanut odors in a three-chamber preference test. In absence of OT stimulation, significant preference for the peanut odor chamber was observed which was abolished in the presence of OT stimulation. Perhaps providing a foundation for this modulation in behavior, we found that OT stimulation significantly increased the number of c-Fos positive neurons in not only the OT, but also in forebrain structures essential to motivated behaviors, including the nucleus accumbens and lateral septum. The present results support the notion that the OT is integral to the display of motivated behavior and possesses the capacity to modulate odor hedonics either by directly altering odor processing or perhaps by indirect actions on brain reward and motivation structures.

    Over the last decade, oxytocin (OT) has received focus in numerous studies associating intranasal administration of this peptide with various aspects of human social behavior. These studies in humans are inspired by animal research, especially in rodents, showing that central manipulations of the OT system affect behavioral phenotypes related to social cognition, including parental behavior, social bonding, and individual recognition. Taken together, these studies in humans appear to provide compelling, but sometimes bewildering, evidence for the role of OT in influencing a vast array of complex social cognitive processes in humans. In this article, we investigate to what extent the human intranasal OT literature lends support to the hypothesis that intranasal OT consistently influences a wide spectrum of social behavior in humans. We do this by considering statistical features of studies within this field, including factors like statistical power, prestudy odds, and bias. Our conclusion is that intranasal OT studies are generally underpowered and that there is a high probability that most of the published intranasal OT findings do not represent true effects. Thus, the remarkable reports that intranasal OT influences a large number of human social behaviors should be viewed with healthy skepticism, and we make recommendations to improve the reliability of human OT studies in the future.

    The central melanocortin (MC) system has been widely studied for its effects on food intake and sexual behavior. However, the MC system, and more specifically the MC4 receptor (MC4R), also interacts with neurochemical systems that regulate socioemotional behaviors, including oxytocin (OT) and dopamine. In monogamous prairie voles, OT and dopamine interact to promote partner preference formation, a laboratory measure of an enduring social bond between mates. Here we investigated the effects of MC receptor activation on partner preference formation in prairie voles, as well as the interaction between the MC and OT systems during this process. Peripheral administration of the brain penetrant MC3/4R receptor peptide agonist, Melanotan II (MTII), and the highly selective, small-molecule MC4R agonist, Pf-446687, enhanced partner preference formation in the prairie vole, but not in the non-monogamous meadow vole. MTII-induced partner preferences were enduring, as they were present 1 week after drug manipulation. The prosocial effects of MCR agonists may be mediated, in part, through modulation of OT, as coadministration of an OT receptor antagonist prevented MTII-induced partner preferences. MTII also selectively activated hypothalamic OT neurons and potentiated central OT release. As OT has been shown to enhance some aspects of social cognition in humans, our data suggest that the MC4R may be a viable therapeutic target for enhancing social function in psychiatric disorders, including autism spectrum disorders and schizophrenia, potentially through activation of the OT system.
