    Administrative growth in higher education does not equal administrative bloat. A variety of external and internal forces have caused growth to occur. Faculty and administration alike must join through a process of shared governance to identify bloat when it does occur, select a strategy to combat it, and redeploy resources. (MSE)

    Ten to 25% of healthy persons experience bloating. It is particularly common in persons with the irritable bowel syndrome and constipation. While the cause of bloating remains unknown old explanations such as a excessive intestinal gas, exaggerated lumbar lordosis and psychiatric problems have been disproved. New suggestions include recent weight gain, weak or inappropriately relaxed abdominal muscles, an inappropriately contracted diaphragm and retained fluid in loops of distal small bowel. ...

    Bloating and abdominal distention are common complaints present in quite a number of organic and functional diseases. An important subject in traditional Persian medicine is digestive disorders, particularly bloating and its etiology. This is a literature review study conducted on The Canon in Medicine written by Avicenna and using the keywords: bloating, gas. In this article, causes for bloating, according to Avicenna, include diet causes, inappropriate lifestyle, gastrointestinal, and miscellaneous reasons. These were compared with causes suggested in modern medicine. Avicenna classifies causes based on the place of origin into upper part of the abdomen (stomach) and intestinal part of the abdomen. Also, 38 medicinal plants used as remedies were listed. Modern scientific data support all bloating causes that have been mentioned in the canon. Obviously, some causes such as uterine disorders and posterior nasal discharge need to be studied further. PMID:26763047

    Plant genome size variation is a dynamic process of bloating and purging DNA. While it was thought plants were on a path to obesity through continual DNA bloating, recent research supports that most plants activity purge DNA. Plant genome size research has greatly benefited from the cataloguing of genome size estimates at the Kew Plant DNA C-values Database, and the recent availability of over 50 fully sequenced and published plant genomes. The emerging trend is that plant genomes bloat due to the copy-and-paste proliferation of a few long terminal repeat retrotransposons (LTRs) and aggressively purge these proliferating LTRs through several mechanisms including illegitimate and incomplete recombination, and double-strand break repair through non-homologous end joining. However, ultra-small genomes such as Utricularia gibba (Bladderwort), which is 82 megabases (Mb), purge excess DNA through genome fractionation and neofunctionalization during multiple rounds of whole genome duplication (WGD). In contrast, the largest published genome, Picea abies (Norway Spruce) at 19 800 Mb, has no detectable WGD but has bloated with diverse and diverged LTRs that either have evaded purging mechanisms or these purging mechanism are absent in gymnosperms. Finally, advances in DNA methylation studies suggest that smaller genomes have a more aggressive epigenomic surveillance system to purge young LTR retrotransposons, which is less active or missing in larger genomes like the bloated gymnosperms. While genome size may not reflect genome complexity, evidence is mounting that genome size may reflect evolutionary status. PMID:24651721

    Abdominal bloating is commonly reported by men and women of all ages. Bloating occurs in nearly all patients with irritable bowel syndrome, and it also occurs in patients with other functional and organic disorders. Bloating is frequently disturbing to patients and frustrating to clinicians, as effective treatments are limited and are not universally successful. Although the terms bloating and abdominal distention are often used interchangeably, these symptoms likely involve different pathoph...

    Poli, Riccardo

    In this paper a simple modification of the Tarpeian bloat-control method is presented which allows one to dynamically set the parameters of the method in such a way to guarantee that the mean program size will either keep a particular value (e.g., its initial value) or will follow a schedule chosen by the user. The mathematical derivation of the technique as well as its numerical and empirical corroboration are presented.

    Frothy bloat is a serious metabolic disorder that affects stocker cattle grazing hard red winter wheat forage in the Southern Great Plains causing reduced performance, morbidity, and mortality. We hypothesize that a microbial dysbiosis develops in the rumen microbiome of stocker cattle when grazing on high quality winter wheat pasture that predisposes them to frothy bloat risk. In this study, rumen contents were harvested from six cannulated steers grazing hard red winter wheat (three with bloat score “2” and three with bloat score “0”), extracted for genomic DNA and subjected to 16S rDNA and shotgun sequencing on 454/Roche platform. Approximately 1.5 million reads were sequenced, assembled and assigned for phylogenetic and functional annotations. Bacteria predominated up to 84% of the sequences while archaea contributed to nearly 5% of the sequences. The abundance of archaea was higher in bloated animals (P 70%) in non-bloated samples. However, the abundance and diversity of CaZymes were greatly reduced in bloated samples indicating the disruption of carbohydrate metabolism. We conclude that mild to moderate frothy bloat results from tradeoffs both within and between microbial domains due to greater competition for substrates that are of limited availability as a result of biofilm formation.

    2012-01-01

    Being able to predict the human oral bioavailability for a potential new drug is extremely important for the drug discovery process. This problem has been addressed by several prediction tools, with Genetic Programming providing some of the best results ever achieved. In this paper we use the newest developments of Genetic Programming, in particular the latest bloat control method, Operator Equalisation, to find out how much improvement we can achieve on this problem. We show examples of some actual solutions and discuss their quality, comparing them with previously published results. We identify some unexpected behaviours related to overfitting, and discuss the way for further improving the practical usage of the Genetic Programming approach. PMID:23356009

  13. Thermal detoxification and bloating of chromium(VI) with bentonite

    International Nuclear Information System (INIS)

    This study stabilizes and bloats Cr(VI)-sorbed bentonite by heating at high temperature. Cr leaching decreases with increasing temperatures. Heating the sample at 1100 oC results in a non-detectable Cr concentration in the leachate, equivalent to a Cr leaching percent less than 0.001% (i.e., Cr TCLP concentration -1 of leachate). Morphology observed with a scanning electron microscopy indicates the occurrence of sintering of the sample heated at 1100 oC. The heated samples also show the occurrence of a vesicant process at 1100 oC. X-ray absorption spectroscopy results indicate that heating at 500 oC for 4 h can convert approximately 87% Cr(VI) into Cr(III) that is negligibly toxic; Cr2O3 was detected to be the most abundant Cr species. After heating at higher temperatures, namely 900-1100 oC, almost all doped Cr(VI) is reduced to Cr(III) as inferred from the height of the pre-edge peak of XANES spectra and/or from XANES simulation.

    This article describes a nursing experience applying the protocol of bilateral Zusanli (ST-36) acupressure to reduce abdominal bloating in a colon cancer patient who had undergone a right hemicolectomy. The period of care was between November 13 and November 23, 2014. Data were collected through direct care, interviews, observation, and physical assessment. The main health problems of the patient included anxiety, surgical wound pain, and abdominal bloating. We provided pre- and postoperative routine nursing care, wound pain management, and the protocol of Zusanli (ST-36) acupressure for reducing abdominal bloating. Results of care recorded the first passage of flatus and intestinal motility during the second postoperative day, with no complaints of bloating from the fourth postoperative day. The subject exhibited a relaxed mood and slept soundly following each acupressure session. Furthermore, the subject reported experiencing no abdominal bloating during the week following discharge, during which he continued to follow the acupressure protocol. This article provides support via an instance of nursing care for the effectiveness of the Zusanli (ST-36) acupressure in improving abdominal bloating and thus reducing the complications of hemicolectomy surgery.

    Recent studies have demonstrated differences in the intestinal microbiota between patients with irritable bowel syndrome (IBS) and healthy controls (HC), suggesting a role for the intestinal microbiota in the pathogenesis of IBS. Alterations in the microbiota have also been implicated in the pathogenesis of abdominal bloating, a commonly reported symptom in IBS. We investigated the relationship between the intestinal microbiota, abdominal bloating, and altered bowel patterns in a cohort of patients with IBS and HC. The 16S rRNA gene from fresh fecal samples was amplified and pyrosequenced by using Roche-454 Titanium chemistry. A Core Measurable Microbiome (CMM) was generated for Operational Taxonomic Unit (OTU) detected in >75% of all samples and compositional features of CMM were compared between groups by Linear Discriminant Analysis (LDA). IBS differentiated from HC by LDA using continuous variation in the species/OTUs or the CMM genera. When subcategorized based on bloating symptoms and bowel characteristics, the same subjects were also well differentiated from one another and from HC. ANOVA analysis showed quantitative species/OTU differences between the subgroups including IBS with and without bloating, and subtypes based on bowel characteristics. The clear LDA differentiation and the significant microbial taxa differences between the groups imply a significant association of the microbiota with bloating symptoms and bowel characteristics in IBS. These changes in the microbiota may serve as a biomarker for IBS and its clinical subtypes and suggest a role for the intestinal microbiota in the pathogenesis of the main symptoms of the disorder.

  16. Holistic Acupuncture approach to idiopathic refractory nausea, abdominal pain and bloating

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    AIM: To evaluate the effectiveness of a holistic acupuncture approach on nausea, pain, bloating and electrogastrogram (EGG) parameters in patients with intractable symptoms. METHODS: Twelve patients with no or mild nausea (those without nausea had bloating or pain) and 10 with a history of moderate to severe nausea were referred for acupuncture. All underwent an EGG and were treated at acupuncture points PC6, SP4 and DU20. Visual analog scales (VAS) assessing severity of nausea, pain and bloating were obtained before and after acupuncture treatment. Nineteen patients received three and three patients received two treatments. RESULTS: VAS scores for nausea reflected the clinical assessment and differed significantly between mild and moderate/severe nausea groups. Acupuncture significantly improved severity of nausea in both groups with improved pre-treatment nausea between the first and third treatments in the moderate/severe nausea group. Pain scores improved with acupuncture in the mild nausea group only and bloating improved only with the first treatment in this group. Patients with bloating with VAS scores greater than 35 pre-treatment improved with acupuncture and over all VAS scores for pain improved with treatment. Acupuncture increased the power in the 2.7 to 3.5 cpm range in the EGG. CONCLUSION: In this uncontrolled clinical study, a holistic acupuncture approach significantly improved nausea in patients with refractory symptoms and increased the power in the 2.7-3.5 cpm component of the electrogastrogram. Bloating and pain VAS scores improved acutely with treatment. This study suggests that acupuncture may be effective in this refractory group of patients and further study using appropriate controls is warranted.

  17. Modeling of Dephosphorization using Bloated Droplet Theory in Basic Oxygen Steelmaking

    2015-02-01

    A considerable fraction of refining of hot metal in basic oxygen steelmaking is carried out in emulsion layer by interaction between the metal droplets and slag. The top oxygen blowing ejects metal droplets into the slag which then undergo refining reactions and return to the metal bath. During this period, the carbon in metal droplets reacts with available oxygen to form carbon monoxide. Above a certain threshold decarburization rate, the evolved carbon monoxide inside the droplet causes the droplet to bloat which increases its surface area. The bloating affects the residence time and the rate of certain interfacial reactions. Here, efforts have been made to study dephosphorization in metal droplet in emulsion by coupling dephosphorization kinetics with the 'bloated droplet theory'. As observed in industrial furnaces, the calculated phosphorous concentration in droplet was found to be lower than that of metal bath. Dephosphorization model developed using mixed transport control model was found to fit industrial data. The results obtained were in satisfactory agreement with the available data and a step ahead in improving the understanding of dephosphorization in steelmaking.

  18. Controlling The Problem Of Bloating Using Stepwise Crossover And Double Mutation Technique

    2011-12-01

    Full Text Available During the evolution of solutions using genetic programming (GP there is generally an increase inaverage tree size without a corresponding increase in fitness—a phenomenon commonly referred to asbloat. The conception of “bloat” in Genetic Programming is a well naturalized phenomenoncharacterized by variable-length genomes gradually maturating in size during evolution. “In a very realsense, bloating makes genetic programming a race against time, to find the best solution possible beforebloat puts an effective stop to the search.” In this paper we are proposing a Stepwise crossover anddouble mutation operation in order to reduce the bloat. In this especial crossover operation we are usinglocal elitism replacement in combination with depth limit and size of the trees to reduce the problem ofbloat substantially without compromising the performance. The use of local elitism in crossover andmutation increases the accuracy of the operation and also reduces the problem of bloat and furtherimproves the performance. To shew our approach we have designed a Multiclass Classifier using GP bytaking few benchmark datasets.

    This paper reports a comparison of several bloat control methods and also evaluates a recent proposal for limiting the size of the individuals: a genetic operator called prune and plant. The aim of this work is to test the adequacy of this method. Since a preliminary study of the method has already shown promising results, we have performed a thorough study in a set of benchmark problems aiming at demonstrating the utility of the new approach. Prune and plant has obtained results that maintain the quality of the final solutions in terms of fitness while achieving a substantial reduction of the mean tree size in all four problem domains considered. In addition, in one of these problem domains, prune and plant has demonstrated to be better in terms of fitness, size reduction, and time consumption than any of the other bloat control techniques under comparison. The experimental part of the study presents a comparison of performance in terms of phenotypic and genotypic diversity. This comparison study can provide the practitioner with some relevant clues as to which bloat control method is better suited to a particular problem and whether the advantage of a method does or does not derive from its influence on the genetic pool diversity.

    Smith, James F., III; Nguyen, ThanhVu H.

    2007-04-01

    A data mining procedure for automatic determination of fuzzy decision tree structure using a genetic program (GP) is discussed. A GP is an algorithm that evolves other algorithms or mathematical expressions. Innovative methods for accelerating convergence of the data mining procedure and reducing bloat are given. In genetic programming, bloat refers to excessive tree growth. It has been observed that the trees in the evolving GP population will grow by a factor of three every 50 generations. When evolving mathematical expressions much of the bloat is due to the expressions not being in algebraically simplest form. So a bloat reduction method based on automated computer algebra has been introduced. The effectiveness of this procedure is discussed. Also, rules based on fuzzy logic have been introduced into the GP to accelerate convergence, reduce bloat and produce a solution more readily understood by the human user. These rules are discussed as well as other techniques for convergence improvement and bloat control. Comparisons between trees created using a genetic program and those constructed solely by interviewing experts are made. A new co-evolutionary method that improves the control logic evolved by the GP by having a genetic algorithm evolve pathological scenarios is discussed. The effect on the control logic is considered. Finally, additional methods that have been used to validate the data mining algorithm are referenced.

  2. Comparative review of foam formation in biogas plants and ruminant bloat

    2012-12-15

    This review gives an overview of the current knowledge concerning the problem of foam formation in the process of anaerobic digestion in biogas plants that utilize renewable resources or biogenic waste material for biogas production. Process upsets in biogas production induced by foam formation can have a negative impact on the efficiency of biogas plants. The foam can block gas pipes and cause severe damage to the bioreactor equipment, ranging from a failure of the feeders to a damage of the roof of the biogas plant. The most common foam removal methods - stirring in the foam, adding anti-foaming agents, diminishing substrate feeding, and altering the biogas reactor management - are not always successful. However, the reasons for the excessive foam formation during the biogas production process have not yet been elucidated in detail. In contrast, foam building in the rumen of ruminants as a cause for bloat has been studied thoroughly. In general, the interaction between proteins, polysaccharides (mucilage), and small plant particles is assumed to be the crucial factor. As the fermentation process in the rumen has many similarities with the biogas production process, the current research results on bloat in ruminants are summarized and compared with the process of foaming in biogas plants.

  3. Bloated stars as agn broad line clouds the emission line spectrum

    1994-01-01

    The `Bloated Stars Scenario' proposes that AGN broad line emission originates in the winds or envelopes of bloated stars (BS). Its main advantage over BLR cloud models is the gravitational confinement of the gas and its major difficulty the large estimated number of BSs and resulting high mass loss rate. We calculate the emission line spectrum by a detailed numerical photoionization code for a wide range of wind structures and a detailed QSO nucleus model with L(ion)=7E45 erg/s, M(bh)=8E7 Mo. The size and boundary density of the BS wind are determined by various processes: Comptonization by the central continuum source, calculated self consistently, tidal disruption by the black hole and the limit set by the wind's finite mass. We find that the emission spectrum is mainly determined by the conditions at the boundary of the line emitting fraction of the wind rather than by its internal structure. Comptonization results in very high ionization parameters at the boundary which produces an excess of unobserved br...

    1996-01-01

    The `Bloated Stars Scenario' proposes that AGN broad line emission originates in the winds or envelopes of bloated stars (BS). Alexander and Netzer (1994, 1996) established that ~ 5e4 BSs with dense, decelerating winds can reproduce the observed emission line spectrum and line profiles while avoiding rapid collisional destruction. Here, I investigate a third prediction of the model, related to the size of the broad line region, by deriving the emission line response to variations in the ionizing continuum (`line reverberation') and comparing it to observations. The expected time lags, as well as the order of response of the various lines, strongly depend on the typical variability time scale of the ionizing continuum. The BS model studied here corresponds to a bright Syfert 1 galaxy (Sy1) or a low luminosity QSO. I find that the BS model is consistent with the observed correlation between the Balmer lines time lags and the AGN luminosity, which at present is the only line reverberation information available f...

    We report the discovery of two new low-mass, thermally bloated, hot white dwarfs among the Kepler sample of eclipsing binaries. These are KIC 9164561 and KIC 10727668 with orbital periods of 1.2670 and 2.3058 days, respectively. The current primary in both systems is an A star of about 2 Msun. This brings the number of similar binaries among the Kepler sample to six, and the two new systems have the shortest orbital periods among them. The white dwarf in KIC 9164561 has the largest thermal bloating, compared to its cold degenerate radius, of about a factor of 14. We utilize RV measurements of the A star in KIC 9164561 to determine the white dwarf mass rather accurately: 0.197 +/- 0.005 Msun. The mass of the white dwarf in KIC 10727668 is based on the Doppler boosting signal in the Kepler photometry, and is less accurately determined to be 0.266 +/- 0.035 Msun. Based on the inferred radii and effective temperatures of these two white dwarfs we are able to make an independent theoretical estimate of their masse...

    The Bloated Stars Scenario proposes that AGN broad line emission originates in the winds or envelopes of bloated stars (BS). Alexander and Netzer (1994) established that ~ 5e4 BSs with dense, decelerating winds can reproduce the observed emission line spectrum and avoid rapid collisional destruction. Here, we use the observed properties of AGN line profiles to further constrain the model parameters. In the BS model, the origin of the broad profiles is the stellar velocity field in the vicinity of the central black hole. We use a detailed photoionization code and a model of the stellar distribution function to calculate the BS emission line profiles and compare them to a large sample of AGN CIV, CIII] and MgII profiles. We find that the BSs can reproduce the general shape and width of typical AGN profiles as well as the line ratios if (i) The ionizing luminosity to black hole mass ratio is low enough. (ii) The broad line region size is limited by some cutoff mechanism. (iii) The fraction of the BSs in the stel...

    Full Text Available El meteorismo espumoso bovino es un trastorno digestivo que limita la producción en los bovinos para carne y leche. Muchos factores han sido involucrados como causales del mismo, sin conocerse a ciencia cierta su influencia en el desarrollo de este trastorno. Actualmente no está claro el origen etiológico del meteorismo espumoso y, como consecuencia, no contamos con una medida ciento por ciento segura para su control, resultando la misma únicamente paliativa del problema. Este trabajo resume los aspectos más estudiados y relevantes sobre la etiología del meteorismo espumoso bovino, así como también las medidas de control disponibles hasta la fecha.Frothy bloat is a digestive disorder that limits productivity in dairy and beef cattle. Many factors are involved in the sudden onset of bloat, however, in some cases, there is a lack of supporting evidence for their implication in the development of this disorder. To date, it is unknown what triggers the rapid oncoming of frothy bloat and, as a result, there are no completely effective control measures. This article analyzes the factors that are best characterized and that are most relevant for the development of frothy bloat. Current control measures available for cattle are also reviewed.

  8. KOI 1224: A FOURTH BLOATED HOT WHITE DWARF COMPANION FOUND WITH KEPLER

    International Nuclear Information System (INIS)

    We present an analysis and interpretation of the Kepler binary system KOI 1224. This is the fourth binary found with Kepler that consists of a thermally bloated, hot white dwarf in a close orbit with a more or less normal star of spectral class A or F. As we show, KOI 1224 contains a white dwarf with Teff = 14, 700 ± 1000 K, mass = 0.22 ± 0.02 M☉, and radius = 0.103 ± 0.002 R☉, and an F-star companion of mass 1.59 ± 0.06 M☉ that is somewhat beyond its terminal-age main sequence. The orbital period is quite short at 2.69802 days. The ingredients that are used in the analysis are the Kepler binary light curve, including the detection of the Doppler boosting effect; the NUV and FUV fluxes from the GALEX images of this object; an estimate of the spectral type of the F-star companion; and evolutionary models of the companion designed to match its effective temperature and mean density. The light curve is modeled with a new code named Icarus which we describe in detail. Its features include the full treatment of orbital phase-resolved spectroscopy, Doppler boosting, irradiation effects, and transits/eclipses, which are particularly suited to irradiated eclipsing binaries. We interpret the KOI 1224 system in terms of its likely evolutionary history. We infer that this type of system, containing a bloated hot white dwarf, is the direct descendant of an Algol-type binary. In spite of this basic understanding of the origin of KOI 1224, we discuss a number of problems associated with producing a system with an orbital period this short.

The planet hosting WASP-86 is a F7 star (\\teff\\ = 6330$\\pm$110 K, \\feh\\ = $+$0.23 $\\pm$ 0.14 dex, and age $\\sim$0.8--1~Gyr), WASP-102 is a G0 star (\\teff\\ = 5940$\\pm$140 K, \\feh\\ = $-$0.09$\\pm$ 0.19 dex, and age $\\sim$1~Gyr). These two systems highlight the diversity of planetary radii over similar masses for giant planets with masses between Saturn and Jupiter. WASP-102b shows a larger than model-predicted radius, indicating that the planet is receiving a strong incident flux which contributes to the inflation of its radius. On the other hand, with a density of $\\rho_{pl}$ = 3.24$\\pm$~0.3~$\\rho_{jup}$, WASP-86b is the densest gas giant planet among planets with ma...

    2011-01-01

    We present an analysis and interpretation of the Kepler binary system KOI 1224. This is the fourth binary found with Kepler that consists of a thermally bloated, hot white dwarf in a close orbit with a more or less normal star of spectral class A or F. As we show, KOI 1224 contains a white dwarf with Teff = 14400 +/- 1100 K, mass = 0.20 +/- 0.02 Msun, and radius = 0.103 +/- 0.004 Rsun, and an F-star companion of mass = 1.59 +/- 0.07 Msun that is somewhat beyond its terminal-age main sequence. The orbital period is quite short at 2.69802 days. The ingredients that are used in the analysis are the Kepler binary light curve, including the detection of the Doppler boosting effect; the NUV and FUV fluxes from the Galex images of this object; an estimate of the spectral type of the F-star companion; and evolutionary models of the companion designed to match its effective temperature and mean density. The light curve is modelled with a new code named Icarus which we describe in detail. Its features include the full ...

  11. Self-pathology, the five-factor model, and bloated specific factors: A cautionary tale.

    Oltmanns, Joshua R; Widiger, Thomas A

    2016-04-01

    The five-factor model (FFM) is widely regarded as a useful model for the structure of both normal and maladaptive personality traits. However, recent factor analytic studies have suggested that deficits in the sense of self fall outside the FFM. The current study replicates and extends these findings, illustrating that factors can be situated outside a higher-order domain by including a relatively large number of closely related scales, forming what is known as a bloated specific factor. A total of 1,553 participants (M age = 37.8 years, SD = 13.1) were recruited across 3 studies. One measure of self-pathology (including 15 scales) and 2 measures of the FFM were administered, along with 17 measures of anxiousness and 12 measures of social withdrawal/sociability. Across 2 independent samples and 2 different measures of the FFM, deficits in the sense of self separated from neuroticism when all 15 scales of self-pathology were included. However, self-pathology loaded with FFM neuroticism when only a subset of the self-pathology scales was included. This finding was replicated with measures of social withdrawal/sociability, although only partially replicated with measures of anxiousness. Implications of these findings for past and future factor analytic studies of the structure of psychopathology are discussed. PMID:26845254

    Full Text Available Human decomposition is a mosaic system with an intimate association between biotic and abiotic factors. Despite the integral role of bacteria in the decomposition process, few studies have catalogued bacterial biodiversity for terrestrial scenarios. To explore the microbiome of decomposition, two cadavers were placed at the Southeast Texas Applied Forensic Science facility and allowed to decompose under natural conditions. The bloat stage of decomposition, a stage easily identified in taphonomy and readily attributed to microbial physiology, was targeted. Each cadaver was sampled at two time points, at the onset and end of the bloat stage, from various body sites including internal locations. Bacterial samples were analyzed by pyrosequencing of the 16S rRNA gene. Our data show a shift from aerobic bacteria to anaerobic bacteria in all body sites sampled and demonstrate variation in community structure between bodies, between sample sites within a body, and between initial and end points of the bloat stage within a sample site. These data are best not viewed as points of comparison but rather additive data sets. While some species recovered are the same as those observed in culture-based studies, many are novel. Our results are preliminary and add to a larger emerging data set; a more comprehensive study is needed to further dissect the role of bacteria in human decomposition.

    Some aspects of wheat pasture bloat have been researched extensively, but few studies have evaluated the effect of wheat type or variety on bloat. Eight Gelbvieh x Angus ruminally cannulated heifers (515 +/- 49 kg of BW) and 48 Angus heifers (238 +/- 12 kg of BW) grazed 1-ha pastures of hard-red or soft-red winter wheat (Triticum aestivum L.) to evaluate the effect of wheat variety on bloat potential. In Exp. 1, cattle grazed from November 11 to 22 and from November 26 to December 7, 2006, in a crossover design. In Exp. 2, cattle were shrunk for 20 h and then grazed from December 19 to 20, 2006, and from January 19 to 20, 2007. In both experiments, bloat was scored at 1000 and 1600 h daily. Rumen samples were collected at 0600, 1200, and 1800 h during each of the last 2 d of each period in Exp. 1 and during both days of each period of Exp. 2. Rumen samples were evaluated for pH, foam production and strength, and viscosity. In Exp. 1, cannulated heifers grazing soft-red had a greater (P bloat (21.9 vs. 5.6%) than those grazing hard-red winter wheat, but bloat incidence was low (2.1%) for the stocker cattle, with no difference between hard-red and soft-red winter wheat (P = 0.52). Viscosity of the rumen fluid was affected (P = 0.03) by the wheat variety x time interaction, with soft-red at 1200 and 1800 h being more viscous than soft-red at 0600 h and hard-red at all times. Foam strength, as determined by bubbling CO(2) gas through rumen fluid, had a wheat variety x time interaction (P = 0.02) with both wheat varieties similar at 0600 h but soft-red having greater foam strength at 1200 and 1800 h. In Exp. 2, no bloat was observed, and no differences between wheat varieties were observed for any of the rumen foam measures. Therefore, for these 2 varieties, the soft-red winter wheat had a greater bloat potential than the hard-red winter wheat based on results from the cannulated heifers, but no differences were observed in the frequency of bloat in stocker cattle.

  15. Grain-boundary cavitation and bloating of isostatically hot-pressed magnesia-partially-stabilized zirconia on air annealing

    International Nuclear Information System (INIS)

    Commercially sintered magnesia-partially-stabilized zirconia was densified to near theoretical density by isostatic hot-pressing at 200 MPa and 17000C in argon. Subsequent air annealing above 11000C resulted in bloating of the material due to grain-boundary cavitation. Mass spectrometry of crushed samples detected the evolution of CO2 and possibly CO on annealing; the hot-pressed material showed a sudden gas evolution above 14000C. Preliminary Auger and ESCA analysis identified the presence of carbon as graphite and an undefined carbide in both the sintered and the hot-pressed material

    Research was conducted to determine the effects of level of supplementation with quebracho condensed tannins (CT) on in vitro ruminal fluid gas production, in vivo ruminal fluid protein fractions, bloat dynamics, and ADG of steers grazing winter wheat. Two experiments were conducted to 1) enumerate the effect of ruminal fluid from steers fed quebracho CT (0, 1, and 2% CT/kg of DMI) on in vitro gas and methane production from minced fresh wheat forage; and 2) quantify the influence of CT supplementation on ruminal protein characteristics, biofilm complexes, bloat potential, and ADG of steers grazing wheat pasture. Eighteen ruminally cannulated steers (386 +/- 36 kg of BW) were randomly allocated to 1 of 3 treatments that included a control (water infusion) and 2 CT treatment levels (1 or 2% CT/kg of DMI). Treatments were administered daily (63 d) through the rumen cannula as pre-mixes with warm water (approximately 30 degrees C). Rumen contents were collected 2 h postinfusion (at 1030 to 1130) on d 0, 20, 40, 50, and 60. Bloat was visually scored daily for 5 d each wk. In Exp. 1, supplementation of CT decreased the rate of in vitro gas production in a dose-dependent response. In Exp. 2, ADG increased (P Quebracho CT is potentially a value-added supplement that can decrease the impacts of frothy bloat and increase BW gains in stocker cattle-wheat systems. PMID:16908660

    To solve the disposal problems of solid wastes, dehydrated sewage sludge and Yellow River sediments were tested as components for production of ultra-lightweight ceramsite. The effects of Yellow River sediments addition on the characteristics of ceramsite were investigated. Ceramsite with different Yellow River sediments additions was characterized using thermal analysis, X-ray diffraction, morphological structures analyses, pore size distributions and porosity analyses. Chemical components, especially ratios of SiO2 +Al2O3/Flux, were used to explain the glassy shell formation, physical properties and pores distribution of ultra-lightweight ceramsite;physical forces for instance expansion force and frictional resistance which combined with SiO2+Al2O3/Flux ratios were used to explain the bloating mechanism. Results showed that the maximum addition of Yellow River sediments for making ultra-lightweight ceramsite was 35%. Macropores (between 0.226μm and 0.554μm) of ultra-lightweight ceramsite were dominant in the pore structures of ultra-lightweight ceramsite and its porosity was up to 67.7%. Physical force of expansion force was constant with the variation of Yellow River sediments content and physical force of frictional resistance was decreased with the increase of Yellow River sediments addition. The relationship between expansion and frictional resistance could determine the expansion rate of ceramsite. Larger pores inside the ceramsite bodies could be obtained as Yellow River sediments additions ranged from 10%to 30%. Ceramsite with higher Yellow River sediments additions of 40%(SiO2+Al2O3/Flux ratios 4.25) became denser and have lower porosity. Crystal components analysis proved that the sintering process made some components of raw materials transfer into other crystals having better thermostability.

    We report the discovery of WASP-78b and WASP-79b, two highly-bloated Jupiter-mass exoplanets orbiting F-type host stars. WASP-78b orbits its V=12.0 host star (TYC 5889-271-1) every 2.175 days and WASP-79b orbits its V=10.1 host star (CD-30 1812) every 3.662 days. A simultaneous fit to WASP and TRAPPIST transit photometry and CORALIE radial-velocity measurements yields planetary masses of 0.89 +/- 0.08 M_Jup and 0.90 +/- 0.08 M_Jup, and radii of 1.70 +/- 0.11 R_Jup and 2.09 +/- 0.14 R_Jup, for WASP-78b and WASP-79b, respectively. The planetary equilibrium temperature of T_P = 2350 +/- 80 K for WASP-78b makes it one of the hottest of the currently known exoplanets. The radius of WASP-79b suggests that it is potentially the largest known exoplanet.

Os animais foram encontrados mortos no amanhecer do dia seguinte à transferência, não foram observados sinais clínicos prévios. Os principais achados macroscópicos incluíram aumento de volume abdominal, protrusão de vagina e língua, distensão ruminal, fígado de coloração pálida e aumento do baço. Na histologia, havia congestão e edema pulmonares e hiperplasia linfóide difusa e acentuada no baço. A evidência de ingestão das leguminosas associada aos achados patológicos e à ausência de microrganismos no exame bacteriológico confirmaram o diagnóstico de timpanismo.Leguminous bloat may occur in cattle which graze pastures consisting of lush forages. In a dairy farm located on the municipality of São Francisco de Paula, Rio Grande do Sul, eight out of 66 cows died suddenly after being transferred to a paddock whose pastures were composed of Trifolium repens and Trifolium pratense. Animals were found dead in the morning of the next day after being transferred; no clinical signs were noticed. Main gross findings included enhanced abdominal volume, protrusion and congestion of the tongue and vagina, ruminal distension, pale liver, and enhanced spleen. Histologically, there were lung congestion and edema, and splenic lymphoid hyperplasia. The evidence of leguminous forages consumption associated with the pathological findings and the absence of growth on bacteriology confirmed the diagnosis.

    Full Text Available BACKGROUND: The epidemiology of Functional abdominal bloating (FAB and its impact on health-related quality of life (HRQoL in Chinese people remains unclear. METHODS: Randomised, stratified, multi-stage sampling methodology was used to select a representative sample of the general population from five cities in China (n = 16,078. All respondents completed the modified Rome II questionnaire; 20% were asked to complete the 36-item Short Form (SF-36. The associated factors of FAB were analyzed. The effects of FAB on HRQoL were estimated with gender stratification using propensity score techniques in 20% subsample. RESULTS: Overall, 643 individuals (4.00% had FAB and it was more prevalent in males than in females (4.87% vs. 3.04%, P<0.001. For males, self-reported history of dyspepsia was most strongly associated with FAB (OR = 2.78; 95% CI: 1.59, 4.72. However, the most strongly associated factor was self-reported health status for females (moderate health vs. good health: OR = 2.06, 95% CI: 1.07, 3.96. P = 0.030; poor health vs. good health: OR = 5.71, 95% CI: 2.06, 15.09. Concerning HRQoL, FAB was found to be related to two domains: role limitation due to physical problems (P = 0.030 and bodily pain (P<0.001 in females. While, in males, there were significant differences in multiple domains between those with and without FAB. CONCLUSION: The prevalence of FAB in China was lower than previous reports. Males who had ever been diagnosed with dyspepsia and females who were in a poor self-reported health status were correlated with a higher prevalence of FAB. FAB affected only physical health in females, but impaired both physical and mental health in males.

    Full Text Available In the Amazon region, sprouting pastures of Panicum maximum cause colic and death in horses and mules. To produce the disease two experiments were performed with growing P. maximum cv. 'Mombaça' in penned horses. In Experiment 1, at the beginning of the raining season, 10 horses were fed with recently harvested sprouting P. maximum. Two horses showed colic on the 5th and 11th day after start of the ingestion. In Experiment 2, also during the raining season, the same 10 horses used in Experiment 2 were divided into two groups of 5 horses each. Group 1 received sprouting P. maximum immediately after harvested and Group 2 received the grass 24 hours after harvested. The control group consisted of four animals which were placed in individual pens and fed with Pennisetum purpureum and commercial ration twice a day. One horse from Group 2 showed colic on day 13th after the start of feeding. The other horses of both groups showed intestinal bloat. In both experiments affected horses recovered after the end of the administration. The control group did not showed clinical signs. These results demonstrated that the disease is caused by the ingestion of sprouting P. maximum during the rainy season. The results in experiment 2 showed that P. maximum do not loss toxicity 24 hours after harvesting. Clinical signs suggest that primary alteration caused by P. maximum is intestinal fermentation followed by bloat.Na região Amazônica, Panicum maximum em brotação causa cólica em equinos durante o período chuvoso.

    2012-02-01

    Superior vena cava (SVC) syndrome, or obstruction of blood returning from the head and upper extremities, is a syndrome that is rapidly increasing in the cardiovascular patient population due to the increasing use of transvenous devices such as permanent pacemakers, implantable cardioverter defibrillators (ICDs), and indwelling venous access devices for hemodialysis. This syndrome in the past has been seen predominately in the cancer population with malignancy being the most common reason for SVC syndrome. The management of this syndrome has largely been with a medical/supportive care approach or with surgical bypass. Given the advancement in the field of endovascular interventions and the increasing expertise in performing these procedures, an endovascular approach to relieving the SVC obstruction is rapidly becoming the treatment of choice for these patients. We describe a case of a patient who had a chronic indwelling port-a-cath who developed SVC syndrome, which was treated with an endovascular approach with stenting of the SVC/brachiocephalic vein junction.  PMID:21599752

  10. Is tidal heating sufficient to explain bloated exoplanets? Consistent calculations accounting for finite initial eccentricity

    CERN Document Server

    Leconte, Jérémy; Baraffe, Isabelle; Levrard, Benjamin

    2010-01-01

    In this paper, we present the consistent evolution of short-period exoplanets coupling the tidal and gravothermal evolution of the planet. Contrarily to previous similar studies, our calculations are based on the complete tidal evolution equations of the Hut model, valid at any order in eccentricity, obliquity and spin. We demonstrate, both analytically and numerically, that, except if the system was formed with a nearly circular orbit (e<0.2), solving consistently the complete tidal equations is mandatory to derive correct tidal evolution histories. We show that calculations based on tidal models truncated at second order in eccentricity, as done in all previous studies, lead to erroneous tidal evolutions. As a consequence, tidal energy dissipation rates are severely underestimated in all these calculations and the characteristic timescales for the various orbital parameters evolutions can be wrong by up to three orders in magnitude. Based on these complete, consistent calculations, we revisit the viabili...

  11. VLT transit and occultation photometry for the bloated planet CoRoT-1b

    We present VLT eclipse photometry for the giant planet CoRoT-1b. We observed a transit in the R-band filter and an occultation in a narrow filter centered on 2.09 microns. Our analysis of this new photometry and published radial velocities, in combination with stellar-evolutionary modeling, leads to a planetary mass and radius of 1.07 (+0.13,-0.18) M_Jup and 1.45 (+0.07,-0.13) R_Jup, confirming the very low density previously deduced from CoRoT photometry. The large occultation depth that we measure at 2.09 microns (0.278 (+0.043,-0.066) %) is consistent with thermal emission and is better reproduced by an atmospheric model with no redistribution of the absorbed stellar flux to the night side of the planet.

    2016-01-01

    We report three new transiting hot-Jupiter planets discovered from the WASP surveys combined with radial velocities from OHP/SOPHIE and Euler/CORALIE and photometry from Euler and TRAPPIST. All three planets are inflated, with radii 1.7-1.8 Rjup. All orbit hot stars, F5-F7, and all three stars have evolved, post-MS radii (1.7-2.2 Rsun). Thus the three planets, with orbits of 1.8-3.9 d, are among the most irradiated planets known. This reinforces the correlation between inflated planets and stellar irradiation.

    2007-01-01

    We present photometry of the G0 star HAT-P-1 during six transits of its close-in giant planet, and we refine the estimates of the system parameters. Relative to Jupiter's properties, HAT-P-1b is 1.20 +/- 0.05 times larger and its surface gravity is 2.7 +/- 0.2 times weaker. Although it remains the case that HAT-P-1b is among the least dense of the known sample of transiting exoplanets, its properties are in accord with previously published models of strongly irradiated, coreless, solar-composition giant planets. The times of the transits have a typical accuracy of 1 min and do not depart significantly from a constant period.

    Winn, Joshua N; Carter, Joshua A; Torres, Guillermo; Osip, David J; Beatty, Thomas

    2009-01-01

    We present photometry of two transits of the giant planet WASP-4b with a photometric precision of 400-800 parts per million and a time sampling of 25-40 seconds. The two midtransit times are determined to within 6 seconds. Together with previously published times, the data are consistent with a constant orbital period, giving no compelling evidence for period variations that would be produced by a satellite or additional planets. Analysis of the new photometry, in combination with stellar-evolutionary modeling, gives a planetary mass and radius of 1.237 +/- 0.064 M_jup and 1.365 +/- 0.021 R_jup. The planet is 15% larger than expected based on previously published models of solar-composition giant planets. With data of the quality presented here, the detection of transits of a "super-Earth" of radius 1.75 R_earth would have been possible.

The two midtransit times are determined to within 6 s. Together with previously published times, the data are consistent with a constant orbital period, giving no compelling evidence for period variations that would be produced by a satellite or additional planets. Analysis of the new photometry, in combination with stellar-evolutionary modeling, gives a planetary mass and radius of 1.237 ± 0.064 M Jup and 1.365 ± 0.021 R Jup, respectively.

    2012-01-01

    We report the discovery by the WASP transit survey of a highly-irradiated, massive (2.258 +/- 0.072 MJup) planet which transits a bright (V = 10.6), evolved F8 star every 2.9 days. The planet, WASP-71b, is larger than Jupiter (1.50 +/- 0.11 RJup), but less dense (0.67 +/- 0.14 {\\rho}Jup). We also report spectroscopic observations made during transit with the CORALIE spectrograph, which allow us to detect the Rossiter-McLaughlin effect. We determine the sky-projected angle between the stellar-spin and planetary-orbit axes to be {\\lambda} = 19.8 +/- 9.9 degrees.

  20. Release of bacterial alkaline phosphatase in the rumen of cattle fed a feedlot bloat-provoking diet or a hay diet.

    Science.gov (United States)

    Cheng, K J; Hironaka, R; Costerton, J W

    1976-05-01

    Alkaline phosphatase (APase) was present in the bovine rumen in both cell-free and cell-associated states and levels of the enzyme varied with dietary regime. Reaction product deposition showed that the enzyme was associated with the mixed bacterial population. No enzyme was observed to be associated with protozoa. Trace activity of APase was also detected in the saliva. The presence of large amounts of APase in cell-free rumen fluid of cattle fed fine concentrate feed is believed to be due, in part, to the breakage of bacterial cells that occurs in the rumen.

    2015-04-01

    Acute pancreatitis subsequent to Nissen fundoplication for gastroesophageal reflux disease (GERD) is an extremely rare adverse event. We describe a pediatric case of acute pancreatitis resulting from superior mesenteric artery syndrome (SMAS) and gas bloat after fundoplication. Gas bloat is one of the known postoperative complications after Nissen fundoplication. Poor nutrition status, which is often associated with severe pediatric GERD, is a risk factor for SMAS. In this case, development of gas bloat and SMAS led to the formation of a closed loop and increased intraluminal pressure of the duodenum and pancreatic duct. Many pediatric patients who need anti-reflux surgery face the risk of developing this entity. Preventive measures, such as treatment with prokinetics and frequent small-volume meals, should be considered until improvement of nutritional status after fundoplication. PMID:25868962

  8. A NEW MUTATION OPERATOR IN GENETIC PROGRAMMING

    Directory of Open Access Journals (Sweden)

    Anuradha Purohit

    2013-01-01

    Full Text Available This paper proposes a new type of mutation operator, FEDS (Fitness, Elitism, Depth, and Size mutation in genetic programming. The concept behind the new mutation operator is inspired from already introduced FEDS crossover operator to handle the problem of code bloating. FEDS mutation operates by using local elitism replacement in combination with depth limit and size of the trees to reduce bloat with a subsequent improvement in the performance of trees (program structures. We have designed a multiclass classifier for some benchmark datasets to test the performance of proposed mutation. The results show that when the initial run uses FEDS crossover and the concluding run uses FEDS mutation, then not only is the final result significantly improved but there is reduction in bloat also.

  9. Putrefactive rigor: apparent rigor mortis due to gas distension.

    Science.gov (United States)

    Gill, James R; Landi, Kristen

    2011-09-01

    Artifacts due to decomposition may cause confusion for the initial death investigator, leading to an incorrect suspicion of foul play. Putrefaction is a microorganism-driven process that results in foul odor, skin discoloration, purge, and bloating. Various decompositional gases including methane, hydrogen sulfide, carbon dioxide, and hydrogen will cause the body to bloat. We describe 3 instances of putrefactive gas distension (bloating) that produced the appearance of inappropriate rigor, so-called putrefactive rigor. These gases may distend the body to an extent that the extremities extend and lose contact with their underlying support surface. The medicolegal investigator must recognize that this is not true rigor mortis and the body was not necessarily moved after death for this gravity-defying position to occur. PMID:20375836

    2003-08-01

    Colonic lactulose fermentation induces bloating, but whether it also causes abdominal distension is not known. The aim of this study was to assess the effect of colonic lactulose fermentation on abdominal girth using a new extensometer. We recorded abdominal girth in 24 healthy subjects by means of an extensometer that measures the phase shift of an ultrasound wave propagating in a tube encircling the abdomen. The recordings were continuously made for 3 h after the ingestion of 100 mL of tap water with (16 subjects) or without (eight subjects) 10 g of lactulose. Every 10 min, H2 in the breath was analysed and the intensity of bloating was recorded. Bloating was never reported after water ingestion, whereas it was reported by 10 subjects after lactulose ingestion (P = 0.002). The mean +/- SD changes in abdominal girth in comparison with resting conditions were statistically significant after lactulose ingestion (3 +/- 2.9 mm; P = 0.002) but not after water ingestion (-0.2 +/- 2.7 mm; P = 0.82). The area under the curve of the changes in abdominal girth after lactulose were significantly greater than after water ingestion (P = 0.03). In conclusion, colonic lactulose fermentation induces bloating and abdominal distension. The new extensometer is useful for continuously recording changes in abdominal girth. PMID:12846731

  2. Rumen distension and contraction influence feed preference by sheep.

    Science.gov (United States)

    Villalba, J J; Provenza, F D; Stott, R

    2009-01-01

    Distension of the rumen limits feed intake by livestock. Ruminal dysfunctions due to bloat, which causes distension by accumulation of excessive gas within the rumen, also reduce feeding. We hypothesized that excessive levels of rumen distension cause feed aversions and that preference increases for feeds eaten in association with recovery from bloat. To test these hypotheses, we determined whether 12 commercial crossbred lambs (average initial BW of 43 +/- 2 kg) could associate ingestion of specific feeds with the consequences of increased intraruminal pressure and its subsidence. Six of the lambs were fitted with rumen cannulas and offered ground alfalfa for 30 min after a rubber balloon was inserted into the rumen of each animal and distended with air to volumes of 1.8, 2.5, or 4.5 L. Subsequently, balloons were deflated and alfalfa was offered again for a second period of 30 min. Feed intake was not affected when the balloon was not distended (P = 0.45 to 0.93), but distension reduced feed intake (P bloat-inducing plants and preferences for plants and supplements that relieve the incidence of bloat.

    2014-08-01

    Decomposition can be a highly variable process with stages that are difficult to quantify. Using high accuracy terrestrial laser scanning a repeated three-dimensional (3D) documentation of volumetric changes of a human body during early decomposition is recorded. To determine temporal volumetric variations as well as 3D distribution of the changed locations in the body over time, this paper introduces the use of multiple degenerated cylinder models to provide a reasonable approximation of body parts against which 3D change can be measured and visualized. An iterative closest point algorithm is used for 3D registration, and a method for determining volumetric change is presented. Comparison of the laser scanning estimates of volumetric change shows good agreement with repeated in-situ measurements of abdomen and limb circumference that were taken diurnally. The 3D visualizations of volumetric changes demonstrate that bloat is a process with a beginning, middle, and end rather than a state of presence or absence. Additionally, the 3D visualizations show conclusively that cadaver bloat is not isolated to the abdominal cavity, but also occurs in the limbs. Detailed quantification of the bloat stage of decay has the potential to alter how the beginning and end of bloat are determined by researchers and can provide further insight into the effects of the ecosystem on decomposition.

    Full Text Available With the aim of analyzing the effects of risk factors such as feed, raising system, season, lactation period, gender and animal age on the occurrence of foamy bloat in bovines, a retrospective study was carried out on 60 clinical cases of the illness in bovines treated at the Bovine Clinic of the Universidade Federal Rural de Pernambuco, Garanhuns Campus (Brazil, between January 1989 to December 2007. Epidemiologically, data on risk factors obtained from medical charts were related to the occurrence of foamy bloat. Among the 60 animals affected, 54 (90% received diets with a high content of concentrates; palm was one of the ingredients in the diet of 41 animals. The raising system was semi-intensive to intensive for 48 (80% animals. The majority of animals affected were females (57/60, 44 (84.08% of which were in the lactation phase. A greater occurrence of cases of foamy bloat (62% was recorded in summer. The ruminal fluid in these animals had a pH value that oscillated between 7 and 8, was of a foamy consistency and had a negative effect on the microbiota. The interrelation of risk factors such as diet rich in concentrate, intensive to semi-intensive production system, summer (dry season, the first and second lactation period, associated to the interaction of factors inherent to the individual animal and ruminal microbiota are important to the etiopathology of foamy bloat in the southern-central semi-arid region of the State of Pernambuco, Brazil.

    Breath tests are non-invasive tests and can detect H₂ and CH₄ gases which are produced by bacterial fermentation of unabsorbed intestinal carbohydrate and are excreted in the breath. These tests are used in the diagnosis of carbohydrate malabsorption, small intestinal bacterial overgrowth, and for measuring the orocecal transit time. Malabsorption of carbohydrates is a key trigger of irritable bowel syndrome (IBS)-type symptoms such as diarrhea and/or constipation, bloating, excess flatulence, headaches and lack of energy. Abdominal bloating is a common nonspecific symptom which can negatively impact quality of life. It may reflect dietary imbalance, such as excess fiber intake, or may be a manifestation of IBS. However, bloating may also represent small intestinal bacterial overgrowth. Patients with persistent symptoms of abdominal bloating and distension despite dietary interventions should be referred for H₂ breath testing to determine the presence or absence of bacterial overgrowth. If bacterial overgrowth is identified, patients are typically treated with antibiotics. Evaluation of IBS generally includes testing of other disorders that cause similar symptoms. Carbohydrate malabsorption (lactose, fructose, sorbitol) can cause abdominal fullness, bloating, nausea, abdominal pain, flatulence, and diarrhea, which are similar to the symptoms of IBS. However, it is unclear if these digestive disorders contribute to or cause the symptoms of IBS. Research studies show that a proper diagnosis and effective dietary intervention significantly reduces the severity and frequency of gastrointestinal symptoms in IBS. Thus, diagnosis of malabsorption of these carbohydrates in IBS using a breath test is very important to guide the clinician in the proper treatment of IBS patients. PMID:24976698

    Primary epiploic appendagitis (PEA) is a rare cause of abdominal acute or subacute complaints. Diagnosis of PEA is made when computed tomography (CT) reveals a characteristic lesion. We report on contrast-enhanced CT images of a patient with PEA and regression of inflammation and the reduction in size of the inflamed appendage over the time period of 4 months. Patients with PEA usually recover without medication or surgical treatment within a few weeks. However, due to continuing bloating and irregular bowel movements we investigated carbohydrate malabsorption and diagnosed a fructose malabsorption. Bloating and irregular bowel movements in this patient with PEA were correlated to carbohydrate malabsorption and were treated successfully with a diet free of culprit carbohydrates. PMID:24939434

    DiNicolantonio, James J; Lucan, Sean C

    2015-09-01

    Irritable Bowel Syndrome (IBS) is a condition that may be marked by abdominal pain, bloating, fullness, indigestion, belching, constipation and/or diarrhea. IBS symptoms can result from malabsorption of fructose. Fructose is a monosaccharide found naturally in small quantities in fruits and some vegetables, and in much larger quantities in industrially manufactured sweets with added sugars (e.g. sucrose and high fructose corn syrup). Fructose malabsorption leads to osmotic diarrhea as well as gas and bloating due to fermentation in the colon. A low-fructose diet has been found to improve IBS symptoms in some patients. This paper discusses the prevalence of fructose malabsorption and considers fructose ingestion as a possible cause of--and fructose restriction as a possible dietary treatment for--IBS.

    Irritable bowel syndrome (IBS) is the most common functional bowel disease that affects up to 15% of the US population. The majority of patients with IBS have significant bloating and gas. Recent evidence is beginning to suggest that patients with IBS may have an alteration in the gastrointestinal flora. Specifically, findings suggest that patients with IBS have excessive bacteria in the small bowel, referred to as bacterial overgrowth. Therefore there may be benefits of antibiotic-based ther...

  16. Functional disorders of the stomach

    Koch, K. L.; Stern, R. M.

    1990-01-01

    Gastroenterologists frequently encounter patients who report vague epigastric discomforts or sensations of fullness, bloating, and distention in the upper abdomen. The discomfort is neither burning in character nor severe in intensity; there is no nocturnal pain. The epigastric location of discomfort and lack of radiation may help to exclude biliary tract and pancreatic diseases. Nausea may be present, but there is little or no vomiting. After these patients ingest liquids or solid foods, the symptoms of easy filling or early satiety and increasing discomfort and nausea are almost always present. The patient may only report "indigestion," but a specific chief complaint, such as pain, discomfort, nausea, or bloating may be elicited with further inquiries. Solid foods usually provoke more symptoms than do liquids. Symptoms of early satiety, nausea, bloating, and abdominal discomfort may culminate in the vomiting of undigested food. These vague upper gastrointestinal (GI) symptoms have been termed "dyspepsia." When peptic diseases of the stomach are excluded, the symptom complex has been called "nonulcer" dyspepsia, a vague syndrome with symptoms attributed to stomach dysfunction. Nonulcer dyspepsia has been reviewed recently. Such symptoms, commonly attributed to a "functional" disorder, are very common in clinical practice, with an incidence of 30% of patients. In this review, we will discuss an approach to the evaluation and treatment of patients with symptoms of nausea, early satiety, bloating, and vague epigastric discomfort--dyspeptic symptoms associated with functional stomach disorders. We will review the anatomy and motility of the stomach and suggest potential neuromuscular malfunctions of the stomach that may result in epigastric symptoms. The potential role of stress and other brain-gut interactions, which may underlie these symptoms, will also be reviewed.

    Lactose malabsorption is a common condition caused by reduced expression or activity of lactase in the small intestine. In such patients, lactose intolerance is characterized by abdominal symptoms (e.g. nausea, bloating, and pain) after ingestion of dairy products. The genetic basis of lactose malabsorption is established and several tests for this condition are available, including genetic, endoscopic, and H2-breath tests. In contrast, lactose intolerance is less well understood. Recent stud...

    This study evaluated the effects of hinokitiol (a natural antibacterial compound extracted from Thujopsis dolabrata var. hondai) and an organic acid mixture (citrate content 50%) on ruminal fermentation. Antibacterial properties were examined by measuring minimal inhibitory concentration. Hinokitiol at 1.56µg/mL or an organic acid mixture at 1600µg/mL inhibited Streptococcus bovis growth. The combination of 0.78µg/mL hinokitiol and 200µg/mL of an organic acid mixture also inhibited S. bovis growth. Both hinokitiol and the hinokitiol and an organic acid mixture combination showed strong antibacterial properties on Gram-positive bacteria such as S. bovis, but relatively weak antibacterial activities on Gram-negative bacteria such as Megasphaera elsdenii. Three ruminally cannulated heifers were fed a bloat-producing diet containing barley, pelleted alfalfa meal, soybean meal and salt without long-cut roughage to investigate the ruminal characteristics in vivo. Feeding to heifers a bloat-producing diet containing 7.8mg/kg hinokitiol and 0.2% of an organic acid mixture significantly decreased the increase in stable ingesta volume. Hinokitiol or an organic acid mixture did not affect ruminal volatile fatty acids, protozoa and bacteria. These results suggest that a combination of hinokitiol and an organic acid mixture might reduce frothy bloat in cattle fed high-grain diets. PMID:22250737

    Full Text Available Abstract Background Constipation severity is often defined by symptoms including feelings of complete evacuation, straining, stool frequency and consistency. These descriptors are mostly obtained in the absence of laxative use. For many constipated patients laxative usage is ubiquitous and long standing. Our aim was to determine the impact of laxative use upon the stereotypic constipation descriptors. Methods Patients with confirmed slow transit constipation completed 3-week stool diaries, detailing stool frequency and form, straining, laxative use and pain and bloating scores. Each diary day was classified as being under laxative affect (laxative affected days or not (laxative unaffected days. Unconditional logistic regression was used to assess the affects of laxatives on constipation symptoms. Results Ninety four patients with scintigraphically confirmed slow transit constipation were enrolled in the study. These patients reported a stool frequency of 5.6 ± 4.3 bowel motions/week, only 21 patients reported P P Conclusions The reporting of frequent and loose stools with abdominal pain and/or bloating is common in patients with slow transit constipation. While laxative use is a significant contributor to altering stool frequency and form, laxatives have no apparent affect on pain or bloating or upon a patients feeling of complete evacuation. These factors need to be taken into account when using constipation symptoms to define this population.

    Oral prescription medical foods have long been used in hospital settings but are also appropriate therapies for gastrointestinal disorders in outpatient medical practice. Oral serum-derived bovine immunoglobulin/protein isolate (SBI) has been shown in clinical studies to reduce loose stools and improve stool consistency as well as other symptoms (i.e., abdominal pain, bloating, and urgency) in patients with irritable bowel syndrome with diarrhea (IBS-D) and human immunodeficiency virus-associated enteropathy. This case series reports the outcomes of 14 IBS patients who received SBI as an addition to standard of care at an individual physician's clinical practice. The patients: 2 IBS with constipation (IBS-C), 7 IBS-D, 2 mixed diarrhea and constipation IBS (IBS-M) and 3 undefined IBS (IBS-U; also described by some physicians as IBS-Bloating), ranged in age from 22-87 years. SBI (5 g or 10 g daily dose) was added to the patient's current standard care and followed for several weeks to determine if symptoms were improved with the addition of SBI. Overall, 12 of the 14 patients indicated some level of improvement through direct questioning of the patients regarding changes from the prior visit. One IBS-Bloating patient had a resolution of symptoms and two patients (1 IBS-Bloating and 1 IBS-C) discontinued therapy because of insufficient relief. The 12 patients who continued on therapy reported an overall improvement in symptoms with better stool consistency, decreased frequency as well as reductions in abdominal pain, bloating, distention, and incontinence. In most cases, therapeutic effects of SBI were seen within the first four weeks of therapy with continued improvements at subsequent visits. SBI has a multifaceted mechanism of action and may help to manage IBS by providing a distinct protein source required to normalize bowel function, gastrointestinal microbiota, and nutritionally enhance tight junction protein expression between intestinal epithelial cells.

    Full Text Available Abstract Introduction We have previously reported the association of gastrointestinal and hypoglycemic symptoms, with idiopathic accelerated gastric emptying. We now report the first series of six similar cases. Case presentations Patient 1: A 24-year-old Caucasian man presented to our facility with a six-month history of post-prandial nausea, flatulence, bloating, abdominal discomfort and associated diarrhea. He had associated episodes of fatigue, sweating, anxiety, confusion and craving for sweet foods. Patient 2: A 52-year-old Caucasian woman presented to our facility with a 15-year history of post-prandial bloating, abdominal pain and diarrhea, often associated with nausea, severe sweating, and fatigue. Patient 3: An 18-year-old Caucasian woman presented to our facility with a nine-year history of post-prandial diarrhea, abdominal bloating and pain. There was associated nausea, tremor, lethargy, and craving for sweet foods. Patient 4: A 77-year-old Caucasian woman presented to our facility with a four-month history of epigastric distension, pain after eating and a change in bowel habit. She experienced intermittent severe diarrhea and marked fatigue, nausea and sweating. Patient 5: A 23-year-old Caucasian woman presented to our facility with a two-year history of early satiety, and diarrhea after eating. She also complained of feeling faint and weak between meals, when she became cold and clammy, and on several occasions lost consciousness during these episodes. Patient 6: A 64-year-old Caucasian woman presented to our facility with a 10-year history of nausea, early satiety and profound bloating followed by diarrhea. All symptoms predominantly occurred in the first three hours after eating, when she felt faint, lethargic, and had a craving for sweet foods. In all cases, symptoms were alleviated or resolved by taking sweet food or drink and response to treatment was 90% or greater in all cases. Conclusions This series extends our description

    2011-06-01

    Irritable bowel syndrome (IBS) is a highly prevalent disorder characterized by nonspecific symptoms that can mimic other common medical conditions. A careful history and physical examination may reveal clues that suggest a coexisting or alternative diagnosis, such as small intestinal bacterial overgrowth or celiac disease (CD). Testing for bacterial overgrowth has limitations, but emerging data suggest that antibiotics may be of some benefit in patients with IBS with diarrhea and bloating. CD seems to have a higher prevalence in patients with IBS. Some patients with IBS may have symptomatic improvement on gluten-restricted diets, without histologic or serologic evidence of CD.

    Achieving optimal rumen function requires an understanding of feeds and systems of nutritional evaluation. Key influences on optimal function include achieving good dry matter intake. The function of feeds in the rumen depends on other factors including chemical composition, rate of passage, degradation rate of the feed, availability of other substrates and cofactors, and individual animal variation. This article discusses carbohydrate, protein, and fat metabolism in the rumen, and provides practical means of evaluation of rations in the field. Conditions under which rumen function is suboptimal (ie, acidosis and bloat) are discussed, and methods for control examined. PMID:25249402

    Early and aggressive fluid therapy is critical in correcting the metabolic complications associated with calf diarrhea. Oral electrolyte therapy can be used with success in calves, but careful consideration should be given to the type of oral electrolyte used. Electrolyte solutions with high osmolalities can significantly slow abomasal emptying and can be a risk factor for abomasal bloat in calves. Milk should not be withheld from calves with diarrhea for more than 12 to 24 hours. Hypertonic saline and hypertonic sodium bicarbonate can be used effectively for intravenous fluid therapy on farms when intravenous catheterization is not possible. PMID:24980729

    Full Text Available The laparoscopic fundoplication became the standard treatment for gastro-esophageal reflux disease and hiatal hernia. Nissen and Toupet techniques are the most used surgical procedures. Which of these techniques is superior is a subject of debate. The Nissen procedure appears to be associated with a higher rate of postoperative morbidity (postoperative dysphagia, gas bloat syndrome. It is classically considered the Nissen procedure allows a superior reflux control compared with the Toupet operation. We present our laparoscopic technique which combines the two procedures and which was associated along the time with a low rate of postoperative morbidity and a good reflux control.

    2008-06-01

    The development of a large noncoding fraction in eukaryotic DNA and the phenomenon of the code bloat in the field of evolutionary computations show a striking similarity. This seems to suggest that (in the presence of mechanisms of code growth) the evolution of a complex code cannot be attained without maintaining a large inactive fraction. To test this hypothesis we performed computer simulations of an evolutionary toy model for Turing machines, studying the relations among fitness and coding versus noncoding ratio while varying mutation and code growth rates. The results suggest that, in our model, having a large reservoir of noncoding states constitutes a great (long term) evolutionary advantage.

    Although the surgical treatment of both GERD and obesity is very successful, these procedures have a significant impact on the physiology and function of the proximal GI tract. With the increasing prevalence of both GERD and obesity, more and more patients present at the motility outpatient clinic with symptoms related to surgical interventions for these medical problems. In this review, we describe the main complications following antireflux surgery: dysphagia, gas bloat syndrome, recurrent (persistent) GERD symptoms, and dyspeptic symptoms. The most common motility-related complications of obesity surgery are dumping syndrome and esophageal dysmotility. PMID:22100119

    Even skilled surgeons will have complications after antireflux surgery. Fortunately, the mortality is low (bloat syndrome (up to 85%), dysphagia (10%-50%), diarrhea (18%-33%), and recurrent heartburn (10%-62%). Most of these complications improve during the 3-6 months after surgery. Dietary modifications, pharmacologic therapies, and esophageal dilation may be helpful. Failures after antireflux surgery usually occur within the first 2 years after the initial operation. They fall into 5 patterns: herniation of the fundoplication into the chest, slipped fundoplication, tight fundoplication, paraesophageal hernia, and malposition of the fundoplication. Reoperation rates range from 0%-15% and should be performed by experienced foregut surgeons. PMID:23267868

    Adult‑type hypolactasia (lactase nonpersistence or lactase deficiency) is the most common enzyme deficiency leading to lactose intolerance and primary lactose malabsorption. Clinical presentation of the condition includes symptoms resulting from bacterial fermentation of undigested lactose in the colon, which gives rise to gas bloat, increased motility, and loose stools. Diagnosis of the disease is based on clinical symptoms, biochemical, functional, histochemical and genetic tests. Treatment includes dietary restrictions, namely, use of low‑lactose milk, in which lactose has been prehydrolyzed, or non‑lactose milk. PMID:23222197

  1. Diverticular disease: A therapeutic overview

    Institute of Scientific and Technical Information of China (English)

    Antonio; Tursi

    2010-01-01

    Formation of colonic diverticula, via herniation of the colonic wall, is responsible for the development of diverticulosis. When diverticulosis becomes symptomatic, it becomes diverticular disease. Diverticular disease is common in Western and industrialized countries, and it is associated with numerous abdominal symptoms (including pain, bloating, nausea, diarrhea, and constipation). Standard medical therapies with antibiotics are currently recommended for patients affected by diverticular disease. However, changing concepts on the pathophysiology of the disease suggest that diverticular disease may share many of the hallmarks of inflammatory bowel diseases. On this basis, the addition of therapies using mesalazine and probiotics may enhance treatment eff icacy by shortening the course of the disease and preventing recurrences.

    2005-01-01

    Full Text Available Gastroparesis is a condition of abnormal gastric motility characterised by delayed gastric emptying in the absence of mechanical outlet obstruction. It is seen commonly in people with diabetes but is idiopathic in a third of patients. Symptoms include nausea and vomiting, post-prandial fullness and early satiety, and abdominal bloating and discomfort. Investigations fall into three categories: gastric emptying studies, intraluminal pressure measurements and recording of gastric myoelectrical activity. Nuclear scintigraphy is considered the gold standard for diagnosing and quantifying delayed gastric emptying. Treatment options include diet and behavioural changes, prokinetic drugs and surgical interventions. New advances in drug therapy and gastric electrical stimulation techniques hold considerable promise.

    Cases of a bovine neuropathy are reported in which peripheral nerves show "sausage-shaped" thickenings of the myelin sheaths at different sites of the internode. Clinical signs of dysphagia and chronic rumenal bloat developed after weaning which were attributable to bilateral vagus nerve degeneration. Trunks of the sciatic nerves and brachial plexuses were similarly affected with the animal adopting a weak shuffling gait. Affected animals were the progeny of sire-daughter matings. The lesions are similar to those seen in the tomaculous neuropathies of man. The present study is believed to be the first report of this lesion occurring in domestic animals. PMID:8740237

    Levan is a commonly used dietary fiber of the fructans group. Its impact on health remains undetermined. This double blind controlled study aimed to investigate the effect of 8 weeks' daily consumption of 500 mL of natural orange juice enriched with 11.25 g of levan compared to the same amount of natural orange juice without levan on weight, gastrointestinal symptoms and metabolic profiles of 48 healthy volunteers. The statistical analyses compared between- and within-group findings at baseline, 4 weeks and study closure. The compared parameters were: weight, blood pressure, blood laboratory tests, daily number of defecations, scores of stool consistency, abdominal pain, bloating, gas, dyspepsia, vomiting and heartburn. Despite a higher fiber level recorded in the study group, there was no significant difference in the effect of the two kinds of juices on the studied parameters. Both juices decreased systolic and diastolic pressures, increased sodium level (within normal range), stool number, and bloating scores, and decreased gas scores. In conclusion, levan itself had no effect on weight, gastrointestinal symptoms or metabolic profile of healthy volunteers. Its possible effect on obese, hypertensive or hyperlipidemic patients should be investigated in further studies. PMID:22852055

    Full Text Available Brian E Lacy Division of Gastroenterology and Hepatology, Dartmouth-Hitchcock Medical Center, Lebanon, NH, USA Abstract: Irritable bowel syndrome (IBS is one of the most common gastrointestinal disorders worldwide. The economic impact of IBS on the health care system is substantial, as is the personal impact on patients. Patients with diarrhea-predominant IBS (IBS-D comprise a substantial proportion of the overall IBS population. Primary care providers are often the first point of contact for patients with IBS-D and can accurately diagnose IBS after a careful history and examination without extensive diagnostic tests. Several pharmacologic treatments (eg, loperamide, alosetron, and antidepressants and non-pharmacologic treatments (eg, dietary modification and probiotics are available for IBS-D, but restrictions on use (eg, alosetron or the lack of controlled trial data showing reductions in both global and individual IBS-D symptoms (eg, bloating, pain and stool frequency emphasize the need for alternative treatment options. Two newer medications (eluxadoline and rifaximin were approved in May 2015 for the treatment of IBS-D, and represent new treatment options for this common gastrointestinal condition.

    2016-01-01

    Alfalfa (Medicago sativa L.) is one of the main forages grown in the world. Alfalfa is a winter hardy, drought tolerant, N-fixing legume with a good longevity, high yield, high nutrient levels, high digestibility, unique structural to non-structural components ratio, high dry matter intake, and high animal productivity per hectare. However, its main limitation is its excessively rapid initial rate of protein degradation in the rumen, which results in pasture bloat and inefficient use of protein with consequent excessive excretions of nitrogen into the environment. Proanthocyanidins are secondary plant metabolites that can bind with protein and thereby reduce the rate and extent of ruminal protein degradation. However, these secondary metabolites do not accumulate in alfalfa. This review aims to firstly describe the events involved in the rapid release of protein from alfalfa and its effect on ruminant nutrition, environmental pollution, and pasture bloat; secondly, to describe occurrence, structure, functions and benefits of moderate amounts of proanthocyanidin; and finally, to describe the development of alfalfa which accumulates moderate amounts of proanthocyanidins. The emphasis of this review focuses on the role of proanthocyanidins compounds in structure and nutrition interaction in ruminant livestock systems. PMID:27223279

    Full Text Available Medical records of 31 adult dairy cows suffering from recurrent rumen tympany for at least 1 month duration that underwent exploratory laparotomy and rumenotomy were reviewed and information was obtained on signalment, history, physical examination findings, laboratory findings and surgical findings. Cases were categorized according to surgical findings into 3 groups. Group 1 (n = 10 included cattle with reticuloruminal, metallic foreign bodies and perireticular adhesions/inflammation, group 2 (n = 14 included cattle with reticuloruminal, non-metallic foreign bodies and no perireticular adhesions/inflammation and group 3 (n = 7 included cattle with no reticuloruminal foreign bodies and no perireticular adhesions/inflammation. Anorexia and decreased milk production were the most common clinical signs in all groups. Reluctant to move and arched back were prominent in group 1. In 45% of cases, frothy bloat was associated with the presence of large amounts of reticuloruminal, non-metallic foreign bodies. Collectively, factors that significantly had negative impact on outcome were: presence of perireticular adhesions, feeding finely-ground grain and plasma fibrinogen levels above 600mg dL-1. However, the amount of grain fed per day and type of bloat (free-gas or frothy gas had no significant effect on the outcome. Results of this study suggest that similar to metallic foreign bodies, non-metallic foreign bodies in the reticulorumen of adult dairy cattle are equally important in causing recurrent rumen tympany.

    The origin and configuration of the gas which emits broad lines in Type I active galactic nuclei is not established yet. The lack of small-scale structure in the broad emission-line profiles is consistent with a smooth gas flow, or a clumped flow with many small clouds. An attractive possibility for the origin of many small clouds is the atmospheres of bloated stars, an origin which also provides a natural mechanism for the cloud confinement. Earlier studies of the broad-line profiles have already put strong lower limits on the minimum number of such stars, but these limits are sensitive to the assumed width of the lines produced by each cloud. Here we revisit this problem using high-resolution Keck spectra of the H alpha line in NGC 4395, which has the smallest known broad-line region (~10^14 cm). Only a handful of the required bloated stars (each having r~10^14 cm) could fit into the broad-line region of NGC 4395, yet the observed smoothness of the H alpha line implies a lower limit of ~10^4-10^5 on the num...

  12. Efficacy and tolerability of tegaserod in constipation dominant irritable bowel syndrome

    International Nuclear Information System (INIS)

    Objective: To determine the efficacy and tolerability of tegaserod in the treatment of symptoms of irritable bowel syndrome (IBS) IBS-C patients. Patients and Methods: Tegaserod was administered in a dose of 6 mg (twice-a-day) orally for a period of 6 weeks. Symptoms were assessed before and during treatment using a questionnaire. Results: The mean age of patients was 37.5 years and 81 (69.2%) were males. The study enrolled 117 patients and 101 patients completed the study. Number of bowel movements, symptoms of straining at defecation, stool consistency, bloating, urgency and abdominal pain improved significantly following treatment (p<0.05). Analysis of data in both genders separately showed statistically significant improvement in symptoms of urgency, straining at defecation, abdominal pain and number of bowel movements following treatment. Side effects of diarrhea and vertigo (6 and 1 patients respectively) necessitating discontinuation of treatment were infrequent. Conclusion: Tegaserod given in a dose of 6 mg b.d. is effective and well tolerated in IBS-C patients. It is equally effective in males and females in relieving the symptoms of abdominal pain, bloating, straining at defecation as well as increased in the mean number of bowel movements per week.

    We determined if tall fescue in a mixture with either tannin-containing sainfoin or saponin-containing alfalfa affected cattle foraging behavior, performance, meat quality, and consumer acceptance of meat. Foraging behavior, BW, and pasture biomass before and after grazing were monitored when cattle strip-grazed 3 replications of 2 treatments from May through September 2010 (12 calves/replication) and from June through September 2012 (8 calves/replication). Animals were allowed a choice between tall fescue and sainfoin (SAN) or tall fescue and alfalfa (ALF) growing in strips (fescue, legume, and fescue-legume mixture). Incidence of use (scan samples) of legumes increased from the beginning to the end of the trials (P 0.05). No incidences of bloat were detected. When cattle (3 calves/treatment in 2010 and 8 calves/treatment in 2012) were slaughtered in September to assess meat quality and consumer acceptance, carcasses were lean (4% to 6% fat content of the longissimus muscle), but compared with ALF, SAN had higher marbling scores, quality grades (Select versus Standard), and back fat thicknesses (P 0.05). Thus, cattle incorporated a lower-quality grass into their diets even when legumes were available ad libitum during most grazing trials. Choices between tall fescue and legumes differing in the type of secondary compound (tannins vs. saponins) and bloating potential influenced patterns of forage use by cattle and led to differences in meat quality.

  14. Metamict zircon formed by heavy ion bombardment

    International Nuclear Information System (INIS)

    Zirconium silicate powder is converted into a range of metamict conditions, and finally to a non-crystalline condition by argon or krypton ion bombardment of energies of 1 to 3.5 MeV. The non-crystalline condition is induced by approximately 2 x 1015 ions per cm2. Further irradiation causes the non-crystalline particles to bloat into extended disc shapes. The glassy metamict state creeps under heavy ion irradiation. Under comparable conditions, silicates such as α-quartz bloat into a similar range of glassy shapes, whereas nitrides such as Si3N4 do not. The metamict state is essentially a glass-type random atomic structural arrangement. This formation of extended glassy shapes under ionic bombardment is an alternative method of formation of some of the glassy constituents of chondrules, tektites and lunar agglutinates by cosmic irradiation. The reported sintering under fast neutron irradiation may be explained by the joining of neighboring particles under glassy irradiation creep. (author)

  15. Formation of primordial supermassive stars by rapid mass accretion

    International Nuclear Information System (INIS)

    Supermassive stars (SMSs) forming via very rapid mass accretion ( M-dot ∗≳0.1 M⊙ yr−1) could be precursors of supermassive black holes observed beyond a redshift of about six. Extending our previous work, here we study the evolution of primordial stars growing under such rapid mass accretion until the stellar mass reaches 104–5 M ☉. Our stellar evolution calculations show that a star becomes supermassive while passing through the 'supergiant protostar' stage, whereby the star has a very bloated envelope and a contracting inner core. The stellar radius increases monotonically with the stellar mass until ≅ 100 AU for M * ≳ 104 M ☉, after which the star begins to slowly contract. Because of the large radius, the effective temperature is always less than 104 K during rapid accretion. The accreting material is thus almost completely transparent to the stellar radiation. Only for M * ≳ 105 M ☉ can stellar UV feedback operate and disturb the mass accretion flow. We also examine the pulsation stability of accreting SMSs, showing that the pulsation-driven mass loss does not prevent stellar mass growth. Observational signatures of bloated SMSs should be detectable with future observational facilities such as the James Webb Space Telescope. Our results predict that an inner core of the accreting SMS should suffer from the general relativistic instability soon after the stellar mass exceeds 105 M ☉. An extremely massive black hole should form after the collapse of the inner core.

    Streptococcus bovis is an indigenous resident in the gastrointestinal tracts of both humans and animals. S. bovis is one of the major causes of bacterial endocarditis and has been implicated in the incidence of human colon cancer, possibly due to chronic inflammatory response at the site of intestinal colonization. Certain feeding regimens in ruminants can lead to overgrowth of S. bovis in the rumen, resulting in the over-production of lactate and capsular polysaccharide causing acute ruminal acidosis and bloat, respectively. There are multiple strategies in controlling acute lactic acidosis and bloat. The incidence of the two diseases may be controlled by strict dietary management. Gradual introduction of grain-based diets and the feeding of coarsely chopped roughage decrease the incidence of the two disease entities. Ionophores, which have been used to enhance feed conversion and growth rate in cattle, have been shown to inhibit the growth of lactic acid bacteria in the rumen. Other methods of controlling lactic acid bacteria in the ruminal environment (dietary supplementation of long-chain fatty acids, induction of passive and active immune responses to the bacteria, and the use of lytic bacteriophages) have also been investigated. It is anticipated that through continued in-depth ecological analysis of S. bovis the characteristics responsible for human and animal pathogenesis would be sufficiently identified to a point where more effective control strategies for the control of this bacteria can be developed.

  17. Valorisation of different types of boron-containing wastes for the production of lightweight aggregates

    International Nuclear Information System (INIS)

    Four boron-containing wastes (BW), named as Sieve (SBW), Dewatering (DBW), Thickener (TBW) and Mixture (MBW) waste, from Kirka Boron plant in west Turkey were investigated for the formation of artificial lightweight aggregates (LWA). The characterisation involved chemical, mineralogical and thermal analyses as well as testing of their bloating behaviour by means of heating microscopy. It was found that SBW and DBW present bloating behaviour whereas TBW and MBW do not. Following the above results two mixtures M1 and M2 were prepared with (in wt.%): 20 clay mixture, 40 SBW, 40 DBW and 20 clay mixture, 35 SBW, 35 DBW, 10 quartz sand, respectively. Two different firing modes were applied: (a) from room temperature till 760 deg. C and (b) abrupt heating at 760 deg. C. The obtained bulk density for M1 and M2 pellets is 1.2 g/cm3 and 0.9 g/cm3, respectively. The analysis of microstructure with electron microscopy revealed a glassy phase matrix and an extended formation of both interconnected and isolated, closed pores. The results indicate that SBW and DBW boron-containing wastes combined with a clay mixture and quartz sand can be valorised for the manufacturing of lightweight aggregates.

    Hydrogen breath tests are widely used to explore pathophysiology of functional gastrointestinal (GI) disorders. Small intestinal bacterial overgrowth (SIBO) and carbohydrate malabsorption are disorders detected by these tests that have been proposed to be of great importance for symptoms of GI diseases. Glucose hydrogen breath test is more acceptable for diagnosis of SIBO whereas lactose and fructose hydrogen breath tests are used for detection of lactose and fructose maldigestion respectively. Lactulose hydrogen breath test is also used widely to measure the orocecal transit time for GI motility. These methods are noninvasive and inexpensive. Many patients with functional gut disorders are unaware of the relationship between diet and GI symptoms they present. In particular, patients with chronic symptoms may regard their condition as normal and may not be aware that their symptoms can be effectively managed following a proper diagnosis. Patients with symptoms of abdominal pain, bloating, flatulence and altered bowel movements (diarrhea and constipation), or with a medical diagnosis of irritable bowel syndrome or celiac disease, may have undiagnosed carbohydrate malabsorption or SIBO. Hydrogen breath tests are specific and sensitive diagnostic tests that can be used to either confirm or eliminate the possibility of carbohydrate malabsorption or SIBO in such patients. Breath tests, though valuable tools, are underutilized in evaluating dyspepsia and functional bloating and diarrhea as well as suspected malabsorption. However, because of their simplicity, reproducibility and safety of procedure they are now being substituted to more uncomfortable and expensive techniques that were traditionally used in gastroenterology.

    Full Text Available INTRODUCTION Colon perforation has several causes, including stercoral perforation of the colon, which was first described in 1894. Currently, reported cases are fewer than 100. CASE REPORT Male patient of 67 years old, treated at Huichapan General Hospital, Hidalgo, Mexico, with abdominal pain, bloating and no bowel movements. He referred being constipated for the last ten years. Imaging revealed an extremely dilated sigmoid colon with fecal matter as well as free gas in the peritoneal cavity. The suspicion of stercoral colonic perforation is established. Exploratory laparotomy was performed immediately, finding a perforation and a hard scybalum protruding in the ascending colon. Colectomy, ileostomy and Hartmann´s pouch are performed. After surgery, the condition of the patient worsened and progressed to septic shock and respiratory failure. The patient died four hours after surgery, with the diagnosis of organ failure due to sepsis. LITERATURE REVIEW Stercoral perforation accounts for 3.2% of all colon perforations and is caused by a rupture of the intestinal wall through direct pressure of a fecaloma on the colon. It occurs especially in patients older than 70 years with severe chronic constipation, weakened and/or are hospitalized with multiple medications and immobilized. CONCLUSIONS Stercoral perforation of the colon is a rare cause of bowel perforation, which should be suspected in patients with a history of chronic constipation, acute abdominal pain, bloating and sepsis, in order to intervene in a timely fashion.

    This work focuses on the assessment of technological properties and on the leaching behavior of lightweight aggregates (LWA) produced by incorporating different quantities of air pollution control (APC) residues from municipal solid waste (MSW) incineration. Currently this hazardous waste has been mostly landfilled after stabilization/solidification. The LWA were produced by pelletizing natural clay, APC residues as-received from incineration plant, or after a washing treatment, a small amount of oil and water. The pellets were fired in a laboratory chamber furnace over calcium carbonate. The main technological properties of the LWA were evaluated, mainly concerning morphology, bulk and particle densities, compressive strength, bloating index, water adsorption and porosity. Given that APC residues do not own expansive (bloating) properties, the incorporation into LWA is only possible in moderate quantities, such as 3% as received or 5% after pre-washing treatment. The leaching behavior of heavy metals from sintered LWA using water or acid solutions was investigated, and despite the low acid neutralization capacity of the synthetic aggregates, the released quantities were low over a wide pH range. In conclusion, after a washing pre-treatment and if the percentage of incorporation is low, these residues may be incorporated into LWA. However, the recycling of APC residues from MSW incineration into LWA does not revealed any technical advantage. PMID:24238798

    Patient: Female, 60 Final Diagnosis: Gastroesophageal carcinoma with rectal metastasis Symptoms: Bloating • constipation • weight loss Medication: — Clinical Procedure: Endoscopy • flexible sigmoidoscopy • lower endoscopic ultrasound Specialty: Gastroenterology and Hepatology Objective: Unusual clinical course Background: Gastroesophageal cancers, previously considered rare, are rapidly increasing worldwide. We present here a unique case of gastroesophageal carcinoma with metastasis to the rectum. Case Report: A 60-year-old female patient presented with constipation, bloating, and weight loss of 4-month duration. She had undergone sleeve gastrectomy 6 years before. Endoscopies performed revealed a friable-looking mucosa in the lower esophagus and a polypoid rectal mass. Histopathological examination from both the esophageal and rectal lesions revealed poorly differentiated adenocarcinoma cells. Immunohistochemistry stain from both specimens was positive for CK7 supporting the gastric site primary with metastasis to the rectum. Further evaluation also revealed metastasis to bone and malignant pleural effusion. Chemotherapy with palliative intent was initiated. Conclusions: Colorectal metastasis is commonly seen from cancers of the breast, stomach, melanoma, kidney, prostate, and ovaries. However, colorectal metastasis from gastroesophageal cancer has never been reported in the medical literature. Diagnosis relies on histopathologic examination and immunohistochemical staining of the tumor. Treatment depends on the tumor stage. Tumors with widespread metastatic disease are candidates for palliative chemotherapy. PMID:27558656

    Short and medium term outcomes from laparoscopic antireflux surgery are generally excellent. A small number of patients suffer recurrent reflux or intolerable side-effects and may require reoperation. In this paper we describe our experience of 35 laparoscopic reoperations from a single center. Data on patients undergoing antireflux surgery in our unit has been prospectively collected and includes more than 600 primary laparoscopic antireflux operations since 1993. Laparoscopic reoperations have been performed between 1996 and 2005 for patients suffering recurrent reflux, dysphagia or severe gas bloat symptomatic despite medical treatment. All patients underwent preoperative barium studies and endoscopy with selective manometry and pH studies. Symptomatic outcomes were evaluated at 6 weeks and 12 months with Visick scores. Anatomical results were assessed with barium studies at between 6 and 12 months. Thirty-five laparoscopic reoperations were performed in 20 women and 13 men (median age 56 years). Primary surgery had been performed in our unit in 27 (77%) and elsewhere in eight (23%). Median time from primary surgery was 28.5 months (5-360). Two patients underwent a second reoperation. Indication was recurrent reflux in 28 (80%), dysphagia in five (14%) and gas bloat in two (6%). Thirty-two of the 35 reoperations (91.4%) were completed laparoscopically, median operating time was 120.5 min (65-210) and median hospital stay 2 days. There was no mortality and there were only five minor complications. Twelve-month follow-up was available for 32 reoperations (91%). Overall good symptomatic outcomes were obtained in 26 (74%) Visick I or II at 6 weeks and 24 of 32 (75%) at 12 months. In reoperations for dysphagia/gas bloat there was a relative risk of 4.26 of a poor symptomatic outcome (Visick III or IV) at 12 months compared to those for recurrent reflux (P < 0.05, Fisher's exact test). Laparoscopic reoperation is feasible with low conversion rates and minimal

    AIM:To compare the impact of carbon dioxide (CO2) and air insufflation on patient tolerance/safety in deeply sedated patients undergoing colonoscopy.METHODS:Patients referred for colonoscopy were randomized to receive either CO2 or air insufflation during the procedure.Both the colonoscopist and patient were blinded to the type of gas used.During the procedure,insertion and withdrawal times,caecal intubation rates,total sedation given and capnography readings were recorded.The level of sedation and magnitude of patient discomfort during the procedure was assessed by a nurse using a visual analogue scale (VAS) (0-3).Patients then graded their level of discomfort and abdominal bloating using a similar VAS.Complications during and after the procedure were recorded.RESULTS:A total of 142 patients were randomized with 72 in the air arm and 70 in the CO2 arm.Mean age between the two study groups were similar.Insertion time to the caecum was quicker in the CO2 group at 7.3 min vs 9.9 min with air (P =0.0083).The average withdrawal times were not significantly different between the two groups.Caecal intubation rates were 94.4% and 100% in the air and CO2 groups respectively (P =0.012).The level of discomfort assessed by the nurse was 0.69 (air) and 0.39 (CO2) (P =0.0155) and by the patient 0.82 (air) and 0.46 (CO2) (P =0.0228).The level of abdominal bloating was 0.97 (air) and 0.36 (CO2) (P =0.001).Capnography readings trended to be higher in the CO2 group at the commencement,caecal intubation,and conclusion of the procedure,even though this was not significantly different when compared to readings obtained during air insufflation.There were no complications in both arms.CONCLUSION:CO2 insuffiation during colonoscopy is more efficacious than air,allowing quicker and better cecal intubation rates.Abdominal discomfort and bloating were significantly less with CO2 insufflation.

  7. Abstract Expression Grammar Symbolic Regression

    Science.gov (United States)

    Korns, Michael F.

    This chapter examines the use of Abstract Expression Grammars to perform the entire Symbolic Regression process without the use of Genetic Programming per se. The techniques explored produce a symbolic regression engine which has absolutely no bloat, which allows total user control of the search space and output formulas, which is faster, and more accurate than the engines produced in our previous papers using Genetic Programming. The genome is an all vector structure with four chromosomes plus additional epigenetic and constraint vectors, allowing total user control of the search space and the final output formulas. A combination of specialized compiler techniques, genetic algorithms, particle swarm, aged layered populations, plus discrete and continuous differential evolution are used to produce an improved symbolic regression sytem. Nine base test cases, from the literature, are used to test the improvement in speed and accuracy. The improved results indicate that these techniques move us a big step closer toward future industrial strength symbolic regression systems.

    To investigate U.S. women's intended care seeking for symptoms associated with ovarian cancer, data from the 2012 HealthStyles Fall survey of U.S. adults were examined. Analyses were limited to women with no history of gynecologic cancer (N = 1726). Logistic regression models for intended care seeking within 2 weeks of symptom onset were developed. A minority of women recognized that unexplained pelvic or abdominal pain (29.9%), unexplained bloating (18.1%), and feeling full after eating a small amount of food (10.1%) can indicate ovarian cancer, and 31.1% mistakenly believed that the Papanicolaou (Pap) test screens for the disease. In the multivariate regression models, the most consistent, significant predictors (p educational efforts should emphasize that symptoms associated with ovarian cancer may also result from benign conditions.

    2016-04-01

    Irritable bowel syndrome (IBS) is a chronic, functional bowel disorder characterized by abdominal pain or discomfort and altered bowel habit. The pathophysiology is unclear, but may include altered gut motility, visceral hypersensitivity, abnormal central pain processing, chronic low-grade intestinal inflammation, or disturbances in the gut microbiome. These etiological mechanisms, alongside environmental factors such as stress and anxiety, vary between individuals and represent potential targets for treatment. Rifaximin is a poorly absorbed oral antibiotic proposed to act on the gut microenvironment, used in the treatment of travelers' diarrhea and hepatic encephalopathy. Clinical trials suggest the drug can reduce global IBS symptoms and improve bloating, abdominal pain, and stool consistency in some patients with non-constipated IBS, leading to Food and Drug Administration approval in the United States. This article considers the pharmacology of rifaximin, the evidence for its use in IBS, and the safety and tolerability of the drug. PMID:26753693

    2016-09-01

    Early in the twenty-first century, novel endoscopic techniques were introduced for the management of gastroesophageal reflux disease, providing minimally invasive ways to eliminate pharmacologic acid inhibition and avoid the need for anti-reflux surgery. These techniques do not significantly alter the anatomy of the gastroesophageal junction, minimizing short- and long-term adverse effects, such as dysphagia and bloating. After extensive clinical testing, many endoscopic therapies were abandoned due to either lack of durable efficacy or unfavorable safety profile. Today, only four such therapies remain clinically available, each with variable levels of clinical validation and market penetration. This review will provide an assessment of these endoscopic therapies, highlighting their respective strengths and weaknesses and their present and future applicability to patients with gastroesophageal reflux disease.

    Cholesterol crystal embolization (CCE) is a rare systemic embolism caused by formation of cholesterol crystals from atherosclerotic plaques. CCE usually occurs during vascular manipulation, such as vascular surgery or endovascular catheter manipulation, or due to anticoagulation or thrombolytic therapy. We report a rare case of intestinal obstruction caused by spontaneous CCE. An 81-year-old man with a history of hypertension was admitted for complaints of abdominal pain, bloating, and anorexia persisting for 4 mo. An abdominal computed tomography revealed intestinal ileus. His symptoms were immediately relieved by an ileus tube insertion, and he was discharged 6 d later. However, these symptoms immediately reappeared and persisted, and partial resection of the small intestine was performed. A histopathological examination indicated that small intestine obstruction was caused by CCE. At the 12-mo follow-up, the patient showed no evidence of CCE recurrence. Thus, in cases of intestinal obstruction, CCE should also be considered. PMID:27022232

    Hemangioma, a most frequently encountered primary benign tumor of the liver, is generally determined incidentally during the course of radiologic tests for other reasons. Most lesions are less than 3 cm and a significant proportion of patients are asymptomatic, although the size and location of the lesion in some patients may be associated with the onset of symptoms. Pressure on the stomach and duodenum of giant hemagiomas developing in the left lobe of the liver, in particular, may result in the development of abdominal pain, nausea, vomiting, and feeling bloated, which are characteristic of a gastric outlet obstruction. A 42-year-old man presented with findings of gastric outlet obstruction and weight loss as a result of a giant hepatic hemangioma. PMID:23438272

    It is suggested that the companion winds, excited by the radiation from the neutron star in PSR 1957 + 20 form only through the combined action of the radiation heat on the companion's atmosphere and the radiation force on the slowly lifting wind. Ballistic simulations suggest that these winds leave only from selected areas of the illuminated surface of the companion; surface currents channel into these regions relatively hot (but altogether cooler than the companion escape velocity) 'coronal' matter from the whole illuminated area. Under suitable conditions, wind particles spend some time trailing the companion at close distances before taking off to escape from the system. This can torque the binary into angular momentum loss that will be as efficient as the one recently observed in PSR 1957 + 20 if the companion is bloated to dimensions close to that of the Roche lobe.

    2010-12-01

    Full Text Available The case of a 68 years old patient, smoking since adolescence, with urban origins, obesity history and gastroesophageal reflux symptoms is presented. The patient was diagnosed with gastroesophageal junction adenocarcinoma type III in the Gastroenterology Department of the Provincial University Hospital of Cienfuegos where he arrived with weight loss of about 20 pounds in four months along with dyspeptic manifestations such as stomach acidity, slow digestion, bloating and epigastric pain unrelated to food consumption. No dysphagia was observed as presentation form of the disease. The patient underwent surgery and chemotherapy and has had a favourable outcome up until today. It was decided to publish this article because of the few cases of gastroesophageal junction adenocarcinoma and especially type III that are commonly presented and also because the diagnosis is, unlike this case, usually made at an advanced stage of the disease

    2015-10-01

    Full Text Available Introduction: Idiopathic Pulmonary Hemosiderosis (IPH is a rare cause of alveolar hemorrhage, which is seen primarily in childhood. Celiac disease is defined as a chronic, immune-mediated enteropathy of the small intestine, caused by exposure to dietary gluten in genetically pre-disposed individuals. Association of IPH and celiac disease is known as Lane Hamilton syndrome. There are limited number of case reports of this syndrome in literature. Case Presentation: Although there were no growth and developmental delay and gastrointestinal symptoms like chronic diarrhea, chronic constipation, vomiting, abdominal bloating and pain in the two patients with IPH, they were diagnosed with Lane Hamilton Syndrome. After initiation of gluten-free diet, their IPH symptoms disappeared and hemoglobin levels were observed to return to normal. Conclusions: Even if there were no gastrointestinal symptoms in a patient with IPH, celiac disease should be investigated. These patients may benefit from gluten free diet and IPH symptoms may disappear.

    Rifaximin is a broad spectrum oral antibiotic with antimicrobial activity against Gram-positive and Gram-negative aerobic and anaerobic bacteria. It is poorly absorbed and thus has a highly favorable safety profile. Rifaximin has been shown to be effective in the treatment of traveler's diarrhea, functional bloating and irritable bowel syndrome, small bowel bacterial overgrowth and in the prevention of recurrent overt hepatic encephalopathy. In addition, there is emerging evidence for a possible beneficial effect of rifaximin in the treatment of uncomplicated diverticular disease and in the prevention of recurrent diverticulitis. The use of rifaximin is associated with a low incidence of development, or persistence of spontaneous bacterial mutants. Moreover, the development of important drug resistance among extra-intestinal flora during rifaximin therapy is unlikely because of minimal systemic absorption and limited cross-resistance of rifaximin with other antimicrobials. This review addresses the current and emerging role of rifaximin in the treatment of gastrointestinal and liver disorders. PMID:27547007

    2011-02-01

    Full Text Available The planetary mass-radius diagram is an observational result of central importance to understand planet formation. We present an updated version of our planet formation model based on the core accretion paradigm which allows us to calculate planetary radii and luminosities during the entire formation and evolution of the planets. We first study with it the formation of Jupiter, and compare with previous works. Then we conduct planetary population synthesis calculations to obtain a synthetic mass-radius diagram which we compare with the observed one. Except for bloated Hot Jupiters which can be explained only with additional mechanisms related to their proximity to the star, we find a good agreement of the general shape of the observed and the synthetic M − R diagram. This shape can be understood with basic concepts of the core accretion model.

    Full Text Available Irritable bowel syndrome (IBS is a group of symptoms manifesting as a functional gastrointestinal (GI disorder in which patients experience abdominal pain, discomfort, and bloating that is often relieved with defecation. IBS is often associated with a host of secondary comorbidities such as anxiety, depression, headaches, and fatigue. In this review, we examined the basic principles of Pancha Kosha (five sheaths of human existence concept from an Indian scripture Taittiriya Upanishad and the pathophysiology of a disease from the Yoga approach, Yoga Vasistha’s Adhi (originated from mind and Vyadhi (ailment/disease concept. An analogy between the age old, the most profound concept of Adhi-Vyadhi, and modern scientific stress-induced dysregulation of brain-gut axis, as it relates to IBS that could pave way for impacting IBS, is emphasized. Based on these perspectives, a plausible Yoga module as a remedial therapy is provided to better manage the primary and secondary symptoms of IBS.

    Non ulcer dyspepsia is one of the most common problems encountered in primary care practice. The underlying pathophysiology of non ulcer dyspepsia is not fully understood, but it is known that this condition is associated with H. pylori infection and motility disorder. The presenting abdominal symptoms are non specific: they include bloating, belching, flatulence, excessive fullness after eating and nausea. Psychological condition such as anxiety, depression and stress do play a role in the recurrence of symptoms. Upper GI endoscopy is necessary in patients who presents with alarm symptoms suggestive of possible underlying organic condition before one makes the diagnosis of non ulcer dyspepsia. Pharmacological therapy using H2 receptor antagonist and proton pump inhibitors are effective for symptom relief. Patient's education and supportive care should be part of the management strategy in recurrent chronic dyspepsia. PMID:18942314

    2007-01-01

    The development of a large non-coding fraction in eukaryotic DNA and the phenomenon of the code-bloat in the field of evolutionary computations show a striking similarity. This seems to suggest that (in the presence of mechanisms of code growth) the evolution of a complex code can't be attained without maintaining a large inactive fraction. To test this hypothesis we performed computer simulations of an evolutionary toy model for Turing machines, studying the relations among fitness and coding/non-coding ratio while varying mutation and code growth rates. The results suggest that, in our model, having a large reservoir of non-coding states constitutes a great (long term) evolutionary advantage.

    Sainfoin (Onobrychis viciifolia) is a tanniniferous legume forage that has potential nutritional and health benefits preventing bloating, reducing nematode larval establishment, improving N utilization, and reducing greenhouse gas emissions. However, the use of sainfoin as a fodder crop in dairy...... cow rations in northwestern Europe is still relatively unknown. The objective of this study was to evaluate the effect of sainfoin silage on nutrient digestibility, animal performance, energy and N utilization, and CH4 production. Six rumen-cannulated, lactating dairy cows with a metabolic body weight...... (BW(0.75)) of 132.5±3.6kg were randomly assigned to either a control (CON) or a sainfoin (SAIN)-based diet over 2 experimental periods of 25 d each in a crossover design. The CON diet was a mixture of grass silage, corn silage, concentrate, and linseed. In the SAIN diet, 50% of grass silage dry matter...

  3. Rational Use of Antibiotics in the Treatment of Functional Bowel Disorders

    2010-07-01

    Full Text Available Functional gastrointestinal symptoms such us bloating, fullness, flatulence, diarrhea, and constipation due to irritable bowel syndrome (IBS were recently attributed to small bowel bacterial overgrowth, a condition depending on the presence of an increased number of bacteria in the small bowel. However, the methodology used to describe this association may be harshly criticized, since it has already been shown to be quite inaccurate. As a result an inappropriate use of antibiotics was consequently generated. In fact, antibiotics could be effective in the treatment of functional complaints, but only in a limited subgroup of patients, characterized by an increase of fermentation at colonic level. In this review, we have examined the papers suggesting a pathophysiological link between IBS and small bowel bacterial overgrowth, underlining its inappropriateness, and put forth our personal view on the rationale for antibiotic use in IBS.

    2014-01-01

    Mantle cell lymphoma is a very aggressive lymphoma with a very poor prognosis. It commonly involves the gastrointestinal tract but rarely presents as primary gastrointestinal lymphoma. The most notable cases of primary gastrointestinal mantle cell lymphomas have been described as multiple lymphomatous polyposis and have a very poor prognosis. We report a case of primary gastrointestinal mantle cell lymphoma that was discovered by endoscopic biopsy of a single duodenal polyp in a 70-year-old woman who was previously treated for Helicobacter pylori gastritis. She presented with a 6-month history of indigestion, heartburn and abdominal bloating. A subsequent workup revealed one extranodal site of involvement, lymphatic involvement below the diaphragm and a normal bone marrow biopsy. We followed a wait-and-watch approach including serial CT scans and blood tests. Two years later, her symptoms have not progressed and her disease has remained stable. PMID:24759605

  5. The evolution of irradiated stars

    International Nuclear Information System (INIS)

    Stars less than a few pc from a quasar or an active galactic nucleus will be subjected to an intense radiation flux. The effects on the structure and evolution of such stars are investigated by evolving models in isotropic radiation baths at constant temperatures ranging from 103.75 to 104. The effects on stars with radiative envelopes are found to be small, while stars with convective envelopes generally increase in size. Consequently, the main sequence evolution of stars of mass ≥ 1 solar mass is little affected, but as red giants, they are 10-100 times larger than normal. Lower-mass stars do grow significantly while still on the main sequence. Redistribution of energy is found to prolong Hertzsprung-gap evolution of all stars and to shorten the main sequence lifetimes of very-low-mass stars. It is found that the bloated giants are likely to undergo extensive mass loss soon after they begin to expand. (author)

  6. Variable Size Genetic Network Programming

    Katagiri, Hironobu; Hirasawa, Kotaro; Hu, Jinglu; Murata, Junichi

    Genetic Network Programming (GNP) is a kind of volutionary methods, which evolves arbitrary directed graph programs. Previously, the program size of GNP was fixed. In the paper, a new method is proposed, where the program size is adaptively changed depending on the frequency of the use of nodes. To control and to decide a program size are important and difficult problems in Evolutionary Computation, especially, a well-known crossover operator tends to cause bloat. We introduce two additional operators, add operator and delete operator, that can change the number of each kind of nodes based on whether a node function is important in the environment or not. Simulation results shows that the proposed method brings about extremely better results compared with ordinary fixed size GNP.

  7. A reexamination of the gravitational lens interpretation of the close QSO pair Q2345 + 007 A,B - Implications for the nature of the Lyman Alpha forest clouds

    International Nuclear Information System (INIS)

    Moderate resolution spectra of the QSO pair Q2345 + 007 A,B are presented for the wavelength range 5127-8967 A. It is found that there is a redshift difference between the two objects of 44 + or - 40 km/s. Results are presented from a search for heavy element absorption systems that may be associated with the object. The results are used to discuss models of the Lyman-alpha clouds. It is suggested that the data are best interpreted if Q2345 + 007 A and B are not a gravitational lens, in which case the characteristic physical size of the Ly-alpha clouds at x = 2 must be about 100 kpc. It is shown that the resulting picture of bloated photoionized clouds is consistent with extimates of the metagalactic ionizing flux. 31 refs

    International Nuclear Information System (INIS)

    We present transit photometry of three exoplanets, TrES-4b, HAT-P-3b, and WASP-12b, allowing for refined estimates of the systems' parameters. TrES-4b and WASP-12b were confirmed to be 'bloated' planets, with radii of 1.706 ± 0.056RJup and 1.736 ± 0.092RJup, respectively. These planets are too large to be explained with standard models of gas giant planets. In contrast, HAT-P-3b has a radius of 0.827 ± 0.055RJup, smaller than a pure hydrogen-helium planet and indicative of a highly metal-enriched composition. Analyses of the transit timings revealed no significant departures from strict periodicity. For TrES-4, our relatively recent observations allow for improvement in the orbital ephemerides, which is useful for planning future observations.

    Beetles associated with carrion play an important role in recycling organic matter in an ecosystem. Four experiments on decomposition, one per season, were conducted in a semirural area in Bahía Blanca, Argentina. Melyridae are reported for the first time of forensic interest. Apart from adults and larvae of Scarabaeidae, thirteen species and two genera of other coleopteran families are new forensic records in Argentina. Diversity, abundance, and species composition of beetles showed differences between stages and seasons. Our results differed from other studies conducted in temperate regions. Four guilds and succession patterns were established in relation to decomposition stages and seasons. Dermestidae (necrophages) predominated in winter during the decomposition process; Staphylinidae (necrophiles) in Fresh and Bloat stages during spring, summer, and autumn; and Histeridae (necrophiles) and Cleridae (omnivores) in the following stages during those seasons. Finally, coleopteran activity, diversity and abundance, and decomposition rate change with biogeoclimatic characteristics, which is of significance in forensics. PMID:26174466

    The planetary mass-radius diagram is an observational result of central importance to understand planet formation. We present an updated version of our planet formation model based on the core accretion paradigm which allows to calculate planetary radii and luminosities during the entire formation and evolution of the planets. We first study with it the formation of Jupiter, and compare with previous works. Then we conduct planetary population synthesis calculations to obtain a synthetic mass-radius diagram which we compare with the observed one. Except for bloated Hot Jupiters which can be explained only with additional mechanisms related to their proximity to the star, we find a good agreement of the general shape of the observed and the synthetic mass-radius diagram. This shape can be understood with basic concepts of the core accretion model.

    2009-01-01

    We present detailed structure and evolution calculations for the first transiting extrasolar planets discovered by the space-based CoRoT mission. Comparisons between theoretical and observed radii provide information on the internal composition of the CoRoT objects. We distinguish three different categories of planets emerging from these discoveries and from previous ground-based surveys: (i) planets explained by standard planetary models including irradiation, (ii) abnormally bloated planets and (iii) massive objects belonging to the overlapping mass regime between planets and brown dwarfs. For the second category, we show that tidal heating can explain the relevant CoRoT objects, providing non-zero eccentricities. We stress that the usual assumption of a quick circularization of the orbit by tides, as usually done in transit light curve analysis, is not justified a priori, as suggested recently by Levrard et al. (2009), and that eccentricity analysis should be carefully redone for some observations. Finally...

  12. Nutcracker syndrome

    International Nuclear Information System (INIS)

    Purpose: The purpose of this case study is to highlight the symptoms of the Nutcracker Syndrome (NCS), the methods of clinical investigations and the importance of differential diagnosis. Introduction: The NCS refers to left renal vein entrapment caused by abnormal branching patterns of the superior mesenteric artery from the aorta.1,2 Clinical case presentation: A 27 years old female presented to the emergency department with complaints of abdominal discomfort, bloating, loose bowel motions and irregular micro-haematuria. The radiologist's report indicated the findings from computed tomography examination to be consistent with anterior NCS. Discussion: In most of the NCS cases the clinical symptoms are non-specific.3 The syndrome is caused by a vascular disorder, but its clinical manifestation can relate to a wide range of abdominal, urological, endovascular or gynaecological pathologies.4 Conclusion: Nutcracker Syndrome is a relatively rare disease and underdiagnosed may lead to left renal vein thrombosis

  13. A Gradient Descent Approximation for Graph Cuts

    Science.gov (United States)

    Yildiz, Alparslan; Akgul, Yusuf Sinan

    Graph cuts have become very popular in many areas of computer vision including segmentation, energy minimization, and 3D reconstruction. Their ability to find optimal results efficiently and the convenience of usage are some of the factors of this popularity. However, there are a few issues with graph cuts, such as inherent sequential nature of popular algorithms and the memory bloat in large scale problems. In this paper, we introduce a novel method for the approximation of the graph cut optimization by posing the problem as a gradient descent formulation. The advantages of our method is the ability to work efficiently on large problems and the possibility of convenient implementation on parallel architectures such as inexpensive Graphics Processing Units (GPUs). We have implemented the proposed method on the Nvidia 8800GTS GPU. The classical segmentation experiments on static images and video data showed the effectiveness of our method.

    2014-12-01

    Seven goats and one ram presented with clinical signs including regurgitation, obtundation, anorexia, apparent pain, and bloat. The animals had escaped from their barn, and it was discovered that they had ingested leaves of Pieris japonica, Japanese pieris, a grayanotoxin-containing plant. Animals were treated with antibiotics, calcium borogluconate, B vitamins, and activated charcoal within the first 24-h postexposure, which was followed by the recovery of the ram and two goats and the death of two goats. Approximately 36 h after Japanese pieris ingestion, one of the three remaining anorectic goats was dosed with intravenous lipid emulsion (ILE). This goat recovered within a few hours. The remaining two goats were given ILE the next day and appeared to recover, but one died a week later of aspiration pneumonia. PMID:25193885

    2016-03-01

    Acute gastric dilation resulting in death was identified in two adult black-footed ferrets (Mustela nigripes) housed at the Smithsonian Conservation Biology Institute in Front Royal, Virginia. Both individuals were adult males (3 and 5 yr) and previously clinically healthy prior to the event. The etiology of gastric dilation in both cases could not be definitively determined, and necropsy revealed severe cardiovascular compromise secondary to bloat. Limited literature is available regarding a syndrome of this type in adult black-footed ferrets. Differential diagnoses considered included gastric dilatation volvulus (GDV), severe gastric distention of unknown origin, and gastric outflow obstruction. Given the severity of this syndrome and the findings in these two cases, acute gastric dilation should be considered in black-footed ferrets presenting with acute abdominal distention, respiratory distress, and cardiovascular compromise.

    We present transit photometry of three exoplanets, TrES-4b, HAT-P-3b, and WASP-12b, allowing for refined estimates of the systems' parameters. TrES-4b and WASP-12b were confirmed to be "bloated" planets, with radii of 1.706 +/- 0.056 R_Jup and 1.736 +/- 0.092 R_Jup, respectively. These planets are too large to be explained with standard models of gas giant planets. In contrast, HAT-P-3b has a radius of 0.827 +/- 0.055 R_Jup, smaller than a pure hydrogen-helium planet and indicative of a highly metal-enriched composition. Analyses of the transit timings revealed no significant departures from strict periodicity. For TrES-4, our relatively recent observations allow for improvement in the orbital ephemerides, which is useful for planning future observations.

  17. Explosions Triggered by Violent Binary-Star Collisions: Application to Eta Carinae and other Eruptive Transients

    CERN Document Server

    Smith, Nathan

    2010-01-01

    This paper discusses a model where a violent periastron collision of stars in an eccentric binary system induces an eruption or explosion seen as a brief transient source, attributed to LBVs, SN impostors, or other transients. The key ingredient is that an evolved primary increases its photospheric radius on relatively short timescales, to a point where the radius is comparable to or larger than the periastron separation in an eccentric binary. In such a configuration, a violent and sudden collision would ensue, possibly leading to substantial mass ejection instead of a binary merger. Repeated periastral grazings in an eccentric system could quickly escalate to a catastrophic encounter, wherein the companion star actually plunges deep inside the photosphere of a bloated primary during periastron, as a result of the primary star increasing its own radius. This is motivated by the case of $\\eta$~Carinae, where such a collision must have occured if conventional estimates of the present-day orbit are correct, and...

  18. A NEARLY POLAR ORBIT FOR THE EXTRASOLAR HOT JUPITER WASP-79b

    International Nuclear Information System (INIS)

    We report the measurement of a spin-orbit misalignment for WASP-79b, a recently discovered, bloated hot Jupiter from the Wide Angle Search for Planets (WASP) survey. Data were obtained using the CYCLOPS2 optical-fiber bundle and its simultaneous calibration system feeding the UCLES spectrograph on the Anglo-Australian Telescope. We have used the Rossiter-McLaughlin effect to determine the sky-projected spin-orbit angle to be λ= -106+19-13o. This result indicates a significant misalignment between the spin axis of the host star and the orbital plane of the planet—the planet being in a nearly polar orbit. WASP-79 is consistent with other stars that have Teff > 6250 K and host hot Jupiters in spin-orbit misalignment

    We report the measurement of a spin-orbit misalignment for WASP-79b, a recently discovered, extremely bloated transiting hot Jupiter from the WASP survey. Data were obtained using the CYCLOPS2 optical-fiber bundle and its simultaneous calibration system feeding the UCLES spectrograph on the Anglo-Australian Telescope at the Siding Spring Observatory. We have used the Rossiter-McLaughlin effect to determine the sky-projected spin-orbit angle to be lambda = -106+10-8 degrees. This result indicates a significant misalignment between the spin axis of the host star and the orbital plane of the planet -- the planet being in a nearly polar orbit. WASP-79 is consistent with other stars that have Teff > 6250K and host hot Jupiters in spin-orbit misalignment.

    2012-01-01

    Modern programming environments provide extensive support for inspecting, analyzing, and testing programs based on the algorithmic structure of a program. Unfortunately, support for inspecting and understanding runtime data structures during execution is typically much more limited. This paper provides a general purpose technique for abstracting and summarizing entire runtime heaps. We describe the abstract heap model and the associated algorithms for transforming a concrete heap dump into the corresponding abstract model as well as algorithms for merging, comparing, and computing changes between abstract models. The abstract model is designed to emphasize high-level concepts about heap-based data structures, such as shape and size, as well as relationships between heap structures, such as sharing and connectivity. We demonstrate the utility and computational tractability of the abstract heap model by building a memory profiler. We then use this tool to check for, pinpoint, and correct sources of memory bloat...

  1. Nissen fundoplication and gastrointestinal-related complications: a guide for the primary care physician.

    Hazan, Tal B; Gamarra, Fernando N; Stawick, Lawrence; Maas, Luis C

    2009-10-01

    Gastroesophageal reflux disease is a common condition affecting many individuals in the Western world. Most patients are managed successfully with acid suppression, while others may require more invasive interventions. The majority of patients undergoing antireflux surgery will have favorable outcomes. A small percentage, however, will be considered surgical failures and will either present with new or recurrent symptoms, or develop postoperative complications. These include, but are not limited to, symptoms such as dysphagia, gas-bloat syndrome, and bowel dysfunctions that may significantly impair the patient's health and quality of life. As the number of antireflux procedures for this condition continue to increase, the number of complications is also likely to become more prevalent. The primary care physician will be challenged to recognize them and initiate appropriate management. In this review, we address the more common gastrointestinal complications of laparoscopic Nissen fundoplication and offer general guidelines in their diagnosis and management. PMID:19738518

    2015-09-01

    First identified in humans by Goodsir in 1842, Sarcina were already known to cause fatal abomasal bloat in animals. Their pathogenicity in humans has only recently been characterized. Sarcina is not inherently pathogenic but, with a gastric ulcer and delayed gastric emptying, can result in perforation. We present a case report of a 32-year-old woman status post-gastric banding presenting with epigastric pain. Upper endoscopy revealed a gastric ulcer near the band. After deflation, upper gastrointestinal series showed passage of contrast and no perforation. Ulcer biopsy showed gastric contents composed of Sarcina. Proton pump inhibitors and antibiotics were administered. Follow-up endoscopy at an outside institution resulted in perforation. This case report supports a growing body of literature that Sarcina organisms contribute to ulcers and perforation. This is the first report of Sarcina in elective bariatric surgery patients, highlighting the high suspicion needed among pathologists evaluating ulcers in this unique surgical population.

    2015-01-01

    Over the past two decades, there has been an increase in the number of anti-reflux operations being performed. This is mostly due to the use of laparoscopic techniques, the increasing prevalence of gastroesophageal reflux disease (GERD) in the population, and the increasing unwillingness of patients to take acid suppressive medications for life. Laparoscopic fundoplication is now widely available in both academic and community hospitals, has a limited length of stay and postoperative recovery time, and is associated with excellent outcomes in carefully selected patients. Although the operation has low mortality and postoperative morbidity, it is associated with late postoperative complications, such as gas bloat syndrome, dysphagia, diarrhea, and recurrent GERD symptoms. This review summarizes the diagnostic evaluation and appropriate management of such postoperative complications. If a reoperation is needed, it should be performed by experienced foregut surgeons.

  4. On the Performance of Different Genetic Programming Approaches for the SORTING Problem.

    Wagner, Markus; Neumann, Frank; Urli, Tommaso

    2015-01-01

    In genetic programming, the size of a solution is typically not specified in advance, and solutions of larger size may have a larger benefit. The flexibility often comes at the cost of the so-called bloat problem: individuals grow without providing additional benefit to the quality of solutions, and the additional elements can block the optimization process. Consequently, problems that are relatively easy to optimize cannot be handled by variable-length evolutionary algorithms. In this article, we analyze different single- and multiobjective algorithms on the sorting problem, a problem that typically lacks independent and additive fitness structures. We complement the theoretical results with comprehensive experiments to indicate the tightness of existing bounds, and to indicate bounds where theoretical results are missing. PMID:25870929

    2013-06-01

    Gastroesophageal reflux disease (GERD) is a prevalent problem resulting in a high level of healthcare consultation and expenditure in the Western World. Although standard medical therapy (in the form of proton pump inhibitor drugs) is effective in the majority of cases, there remains a significant proportion who are refractory to treatment. In addition, surgical therapy (in the form of laparoscopic fundoplication) is not always effective, and in some can be associated with significant side-effects, particularly gas-bloat, flatulence and dysphagia. As such there remains an unmet need in GERD to develop new therapies for refractory cases, and to develop alternatives to fundoplication with fewer side-effects. This article discusses the current state of pharmacological and non-pharmacological emerging therapies for GERD. PMID:23998982

  6. Compressive anneal processing (CAP) of Bi2223 superconducting tapes

    International Nuclear Information System (INIS)

    The conventional processing of oxide powder-in-tube Bi2223 superconductor tapes involves iterative cycles of mechanical deformation to develop texture and reduce porosity, followed by thermal annealing to react components, relieve stress and heal cracks. However, texture and deformation hardening and cracking may limit the ability to obtain the desired grain texture through deformation alone. In addition, desintering of the oxide core occurs during annealing. We have developed a compressive anneal processing (CAP) technique in which a continuous uniaxial pressure is applied during the annealing. The new process is found to promote texture formation, enhance reaction kinetics and prevent desintering and bloating. Our initial results show that the CAP technique significantly improves the critical current density. (author)

  7. Interactive Analysis and Scripting in CIAO 2.0

    Doe, S.; Noble, M.; Smith, R.

    Interpreted scripting languages are now recognized as essential components in the programmer's (and user's) tool chest, and, as amply demonstrated at ADASS 1999, have infiltrated the scientific community with great effect. In this paper we discuss the utilization of the S-Lang interpreted language within the Chandra Data Analysis System (CIAO, or Chandra Interactive Analysis of Observations). In only a few months, with substantial reuse and comparatively little manpower and code bloat, this effort has increased by an order of magnitude the analytical power and extensibility of CIAO. We summarize our design and implementation, and show brief fitting, modeling, and visualization threads that demonstrate capabilities roughly comparable with those of commercial packages. Finally, we present a beta version of the CIAO spectroscopic analysis module, GUIDE -- largely a collection of S-Lang scripts, glued with C++ enhancements to Sherpa and ChIPS -- to illustrate in more depth the range of new functionality and the rapid prototyping now available in CIAO.

  8. An eclipsing millisecond pulsar with a possible main-sequence companion in NGC 6397

    D'Amico, N; Manchester, R N; Sarkissian, J M; Lyne, A G; Camilo, F M

    2001-01-01

    We present the results of one year of pulse timing observations of PSR J1740-5340, an eclipsing millisecond pulsar located in the globular cluster NGC 6397. We have obtained detailed orbital parameters and a precise position for the pulsar. The radio pulsar signal shows frequent interactions with the atmosphere of the companion, and suffers significant and strongly variable delays and intensity variations over a wide range of orbital phases. These characteristics and the binary parameters indicate that the companion may be a bloated main-sequence star or the remnant (still filling its Roche lobe) of the star that spun up the pulsar. In both cases, this would be the first binary millisecond pulsar system with such a companion.

  9. Celiac disease and its effect on human reproduction: a review.

    Soni, Shelly; Badawy, Shawky Z A

    2010-01-01

    Celiac disease is an intestinal inflammatory disease that is triggered by gluten in the diet. Patients present with a wide array of symptoms due to malabsorption that include diarrhea, abdominal pain, bloating and weight loss. In women, this disease may have implications on menstrual and reproductive health. The symptom complex includes delayed menarche, early menopause, secondary amenorrhea, infertility, recurrent miscarriages and intrauterine growth restriction. These women benefit from early diagnosis and treatment. Therefore, celiac disease should be considered and screening tests performed on women presenting with menstrual and reproductive problems and treated accordingly. The objective of this article is to review the current literature on celiac disease and its association with the above-mentioned disorders. PMID:20337200

  10. Pancreatic Lymphoepithelial Cyst with an Intracystic Papillary Projection. Report of a Case

    2009-11-01

    Full Text Available Context Lymphoepithelial cysts of the pancreas show various presentations on imaging studies often making a differential diagnosis difficult. Case report A 58-year-old man was admitted to our hospital with epigastric discomfort and abdominal bloating. Abdominal US was carried out and demonstrated a cystic lesion 5 cm in diameter which included an intracystic projection into the pancreatic body. This intracystic projection was also seen on CT and MR images. On FDG-PET images, the projection was positively visualized. Since we could not exclude a pancreatic cystic neoplasm, a distal pancreatectomy was performed. Postoperative pathological examination demonstrated that the lesion was a lymphoepithelial cyst of the pancreas. There were no atypical cells in the intracystic projection. Conclusion Resection is inevitable when a true pancreatic neoplasm cannot be excluded.

  11. Fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) and nonallergic food intolerance: FODMAPs or food chemicals?

    Barrett, Jacqueline S; Gibson, Peter R

    2012-07-01

    Food intolerance in irritable bowel syndrome (IBS) is increasingly being recognized, with patients convinced that diet plays a role in symptom induction. Evidence is building to implicate fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) in the onset of abdominal pain, bloating, wind and altered bowel habit through their fermentation and osmotic effects. Hypersensitivity to normal levels of luminal distension is known to occur in patients with IBS, with consideration of food chemical intolerance likely to answer many questions about this physiological process. This paper summarizes the evidence and application of the most common approaches to managing food intolerance in IBS: the low-FODMAP diet, the elimination diet for food chemical sensitivity and others including possible noncoeliac gluten intolerance.

    2016-01-01

    The word scleroderma comes from two Greek words, “sclero” meaning hard and “derma” meaning skin. Scleroderma or progressive systemic sclerosis (PSS), a rare condition, was first characterized as a single condition in 1752 by Curzio of Naples. It generally affects woman between 30 and 50 years of age and has a low prevalence. Scleroderma is a disease of the immune system, blood vessels, and connective tissue. Dermal manifestations include stiff, tight, and shiny skin usually of the hands and feet due to swelling and thickening of the connective tissue as they become fibrotic or scarred. Other symptoms include difficulty in swallowing, bloating, abdominal pain, tiredness, lack of energy, weight loss, aching muscles, joints, and bones. The vital organs that may get involved are lungs, heart, and kidneys. We present a case report of PSS in a 45-year-old female patient with characteristic systemic and oral manifestations.

    1992-07-01

    Full Text Available The effect of colloidal bismuth subcitrate (De-Nol on symptoms, Helicobacter pylori status and histological features was studied in 35 patients with non-ulcer dyspepsia. Pain (34 cases and gas bloat (18 were the predominant symptoms. H pylori was present in 26 (74.3% patients. Gastritis and duodenitis were present in 29 of 32 and 22 of 31 cases respectively in whom biopsies were available. Relief in symptoms after treatment was seen in 29 (82.8% cases. Improvement in gastritis and duodenitis was noted in 60.8% and 58.8% respectively; over 70% of H pylori positive patients cleared the organism. These changes did not correlate with the relief in symptoms. We conclude that colloidal bismuth subcitrate is effective in the short term treatment of non-ulcer dyspepsia. It also clears H pylori infection and results in improvement of histological features.

    Given the advances in diagnosis for CD, some patients are detected with symptoms and signs of food intolerance, which have positive antibodies and autoantibodies for coeliac disease, whom present proximal bowel biopsies with chronic nonspecific duodenitis and are not associated with stages 0 and 1 Marsh. On the other hand, patients with bloating, abdominal pain, pondostatural delay, negative antibodies for CD, and chronic nonspecific duodenitis in whom removing cow's milk or gluten, the symptoms remit. There are also celiac patients with biopsies before diagnosis, with chronic nonspecific duodenitis. In this paper, we summarize three brothers with different degrees of chronic duodenitis, one with chronic nonspecific duodenitis, and two with histopathological sings of coeliac disease. It is an invitation to think that chronic nonspecific duodenitis in some patients may be an earlier manifestation of celiac disease. PMID:26544059

  15. AdSplit: Separating smartphone advertising from applications

    CERN Document Server

    Shekhar, Shashi; Wallach, Dan S

    2012-01-01

    A wide variety of smartphone applications today rely on third-party advertising services, which provide libraries that are linked into the hosting application. This situation is undesirable for both the application author and the advertiser. Advertising libraries require additional permissions, resulting in additional permission requests to users. Likewise, a malicious application could simulate the behavior of the advertising library, forging the user's interaction and effectively stealing money from the advertiser. This paper describes AdSplit, where we extended Android to allow an application and its advertising to run as separate processes, under separate user-ids, eliminating the need for applications to request permissions on behalf of their advertising libraries. We also leverage mechanisms from Quire to allow the remote server to validate the authenticity of client-side behavior. In this paper, we quantify the degree of permission bloat caused by advertising, with a study of thousands of downloaded ap...

    A variety of signs and symptoms have been reported in regards to the typical and atypical presentations of CD. It is now well recognised that its onset may occur at any age and that atypical forms of CD are much more prevalent than its classic form (1).In this case, where the patient presented with high BMI and evidence of grade I of fatty liver disease, CD was suspected due to mildly abnormal bloating, cryptogenic hypertransaminasemia, abnormal LFT and poor response to fatty liver treatment. This presentation type is not uncommon; diagnosis was confirmed by the presence of subtotal villous atrophy in the biopsy specimen, positive specific antibody screening (AGA, tTG and EMA antibodies), negative antibody screening and normalization of liver enzymes on a gluten-free diet (Tab. 2, Ref. 13). PMID:24020715

  17. The role of the evaluation of gastric emptying in anorexia nervosa and bulimia

    International Nuclear Information System (INIS)

    Anorexia nervosa and bulimia are common eating disorders that are frequently associated with symptoms of bloating, belching, nausea, and vomiting. The authors currently studying this population with Tc-99m TETA to determine the gastric emptying time (ET) and response to metoclopramide. The authors' findings to date show that the majority (80%) of anorexics have a normal ET; the remainder are delayed. The bulimics demonstrate a normal ET in 34%, delayed in 45%, and rapid in 21%. The response to metoclopramide was good in the delayed anorexic patients and in 71% of bulimic patients treated. The extent of rapidity or delay in ET is being compared with the clinical data including age, weight/height, length and degree of disorder, diet, degree of symptoms, and response to drug and diet therapy. This correlation will help determine the incidence and severity of ET abnormality, the relation of disease and symptom severity to ET, and the effect of different treatments based on the ET

  18. Tolerance of probiotics and prebiotics.

    Marteau, Philippe; Seksik, Philippe

    2004-07-01

    The clinical efficacy of probiotics and prebiotics has been proved in several clinical settings. The authors review their proved or potential side effects. Probiotics as living microorganisms may theoretically be responsible for 4 types of side effects in susceptible individuals: infections, deleterious metabolic activities, excessive immune stimulation, and gene transfer. Very few cases of infection have been observed. These occurred mainly in very sick patients who received probiotic drugs because of severe medical conditions. Prebiotics exert an osmotic effect in the intestinal lumen and are fermented in the colon. They may induce gaseousness and bloating. Abdominal pain and diarrhea only occur with large doses. An increase in gastroesophageal reflux has recently been associated with large daily doses. Tolerance depends on the dose and individual sensitivity factors (probably the presence of irritable bowel syndrome or gastroesophageal reflux), and may be an adaptation to chronic consumption.

    Carum copticum L. commonly known as "Ajwain" is cultivated in many regions of the world including Iran and India, states of Gujarat and Rajasthan. Traditionally, C. copticum has been used in the past for various therapeutic effects including bloating, fatigue, diarrhea, abdominal tumors, abdominal pain, respiratory distress, and loss of appetite. It has other health benefits such as antifungal, antioxidant, antibacterial, antiparasitic, and hypolipidemic effects. This plant contains different important components such as carbohydrates, glucosides, saponins and phenolic compounds (carvacrol), volatile oils (thymol), terpiene, paracymene and beta-pinene, protein, fat, fiber, and minerals including calcium, phosphorus, iron, and nicotinic acid (niacin). In the previous studies, several pharmacological effects were shown for C. copticum. Therefore, in this paper, the pharmacological effects of the plant were reviewed. PMID:25089273

    This review discusses one of the most relevant problems in gastrointestinal clinical practice: lactose intolerance. The role of lactase-persistence alleles the diagnosis of lactose malabsorption the development of lactose intolerance symptoms and its management. Most people are born with the ability to digest lactose, the major carbohydrate in milk and the main source of nutrition until weaning. Approximately, 75% of the world's population loses this ability at some point, while others can digest lactose into adulthood. Symptoms of lactose intolerance include abdominal pain, bloating, flatulence and diarrhea with a considerable intraindividual and interindividual variability in the severity. Diagnosis is most commonly performed by the non invasive lactose hydrogen breath test. Management of lactose intolerance consists of two possible clinical choice not mutually exclusive: alimentary restriction and drug therapy. PMID:24443063

  1. The Feasibility of Using Black Widow Pulsars in Pulsar Timing Arrays for Gravitational Wave Detection

    CERN Document Server

    Bochenek, Christopher; Demorest, Paul

    2015-01-01

    In the past five years, approximately one third of the 65 pulsars discovered by radio observations of Fermi unassociated sources are black widow pulsars (BWPs). BWPs are binary millisecond pulsars with companion masses ranging from 0.01-0.1 solar masses which often exhibit radio eclipses. The bloated companions in BWP systems exert small torques on the system causing the orbit to change on small but measurable time scales. Because adding parameters to a timing model reduces sensitivity to a gravitational wave (GW) signal, the need to fit many orbital frequency derivatives to the timing data is potentially problematic for using BWPs to detect GWs with pulsar timing arrays. Using simulated data with up to four orbital frequency derivatives, we show that fitting for orbital frequency derivatives absorbs less than 5% of the low frequency spectrum expected from a stochastic gravitational wave background signal. Furthermore, this result does not change with orbital period. Therefore, we suggest that if timing syste...

  2. Profound opiate toxicity in gastroparesis following therapeutic dose.

    Craven, Henry; Iftikhar, Hina; Bhatnagar, Pallav

    2016-01-01

    Gastroparesis is defined by the presence of delayed gastric emptying without mechanical obstruction. Patients may present with severe discomfort that can mimic an acute abdomen including abdominal pain, vomiting, nausea, bloating, fullness and early satiety. The prevalence of gastroparesis is estimated at 24 per 100 000 and women are more commonly affected than men. It is associated with a number of conditions including diabetes, Parkinson's disease, multiple sclerosis, previous abdominal surgeries and connective tissue disorders, including scleroderma and Ehlers-Danlos syndrome. Drugs known to prolong gastric transit time, such as opiates, have been shown to exacerbate symptoms. We report a case of a 20-year-old woman with Ehlers-Danlos syndrome who developed respiratory depression after being administered a therapeutic dose of morphine. This occurred due to opiate toxicity confounded by gastroparesis. The patient required further support from intensive care until she recovered, and eventually underwent a gastric pacing procedure for symptomatic relief. PMID:27147632

    2003-08-01

    Members of the family of BPI (bactericidal/permeability-increasing protein)-like proteins are as yet incompletely characterized, particularly in cattle, where full-length sequence information is available for only three of the 13 family members known from other species. Structural bioinformatic analyses incorporating bovine homologues of several members of the BPI-like protein family, including two forms of bovine parotid secretory protein (PSP), showed that this family is also present in cattle. Expression analyses of several members of the BPI-like protein family in cattle, including PSP (Bsp30), von Ebner's minor salivary gland protein (VEMSGP) and lung-specific X protein (LUNX), showed a restricted pattern of expression, consistent with earlier hypotheses that these proteins function in the innate immune response to bacteria. The possible role of bovine PSP in susceptibility to pasture bloat in cattle is discussed. PMID:12887305

    Cheng, K J; Akin, D E; Costerton, J W

    1977-02-01

    The bovine rumen resembles many other ecosystems in that its component bacterial cells are universally surrounded and protected by extracellular structures. The most common form of these structures is a fibrous carbohydrate slime that extends away from the cell and may mediate the attachment of the bacterium to a surface. This attachment is relatively specific and it may occur at the surface of the rumen epithelium or on the cell walls of a specific tissue within the plant-derived food of the animal. The production of the extracellular slime is under nutritional control and slime may be overproduced when soluble carbohydrates are available in high concentration. This overproduction results in cell-cell adhesion among the rumen bacteria with the eventual formation of slime-enclosed microcolonies and, in extreme cases, the generation of sufficient viscosity to cause feedlot bloat.

    A 2-year-old Holstein heifer with a swollen brisket, jugular vein distention, muffled heart sounds, tachycardia, and free gas bloat was examined. Thymic lymphosarcoma was suspected based on a negative agar gel immunodiffusion test for bovine leukemia virus, presence of atypical lymphocytes in pleural fluid, and detection of a mass in the thoracic inlet. Right-sided cardiac catheterization was performed, and markedly increased jugular venous pressures (41 mm Hg) with a pressure gradient of 29 mm Hg immediately cranial to the heart indicated constriction of the cranial vena cava. Immunohistochemical staining of formalin fixed, paraffin-embedded tissue sections of the tumor using a rabbit antihuman T cell, CD3 polyclonal antibody confirmed that the neoplastic lymphocytes were of thymic origin.

    2013-04-01

    In historical buildings of Northern countries high levels of energy are necessary to reach comfortable temperatures especially during the cold season. For this reason historical buildings are now also included in country specific regulations and ordinances to enhance the "energy - efficiency". Since an exterior insulation - as it is commonly used for modern architecture - is incompatible with monument protection, several indoor insulation systems based on historical and ecological materials, are on the market that should improve the thermic performance of a historical building. However, using organic materials as cellulose, loam, weed or wood, bears the risk of fungal growth and thus may lead to health problems in indoor environments. For this reason 5 different ecological indoor insulations systems were tested for their bio-susceptibility against various fungi both under natural conditions - after 2 years of installation in an historical building - and under laboratory conditions with high levels of relative humidity. Fungal growth was evaluated by classical isolation and cultivation as well as by molecular methods. The materials turned out to have a quite different susceptibility towards fungal contamination. Whereas insulations made of bloated Perlite (plaster and board) did not show any fungal growth after 2 years of exposition, the historical insulation made of loam and weed had high cell counts of various fungi. In laboratory experiments wooden softboard represented the best environment for fungal growth. As a result from this study, plaster and board made of bloated Perlite are presented as being the most appropriate materials for thermal insulation at least from the microbiological and hygienic point of view. For future investigations and for the monitoring of fungi in insulation and other building materials we suggest a molecular biology approach with a common protocol for quantitative DNA-extraction and amplification.

    Over a 31-day period, the decomposition process, beetle diversity and succession on clothed pig (Sus scrofa L.) carcasses were studied in open (agricultural land) and shaded habitat (secondary forest) in Southern Mexico. The decomposition process was categorised into five stages: fresh, bloated, active decay, advanced decay and remains. Except for the bloated stage, the elapsed time for each decomposition stage was similar between open and shaded habitats, all carcasses reached an advanced decay stage in seven days, and the fifth stage (remains) was not recorded in any carcass during the time of this study. A total of 6344 beetles, belonging to 130 species and 21 families, were collected during the entire decomposition process, and abundances increased from fresh to advanced decay stages. Staphylinidae, Scarabaeidae and Histeridae were taxonomically and numerically dominant, accounting for 61% of the species richness and 87% of the total abundance. Similar numbers of species (87 and 88 species for open and shaded habitats, respectively), levels of diversity and proportions (open 49%; shaded 48%) of exclusive species were recorded at each habitat. There were significantly distinct beetle communities between habitats and for each stage of decomposition. An indicator species analysis ("IndVal") identified six species associated to open habitats, 10 species to shaded habitats and eight species to advanced decay stages. In addition, 23 beetle species are cited for the first time in the forensic literature. These results showed that open and shaded habitats both provide suitable habitat conditions for the carrion beetle diversity with significant differences in community structure and identity of the species associated to each habitat. This research provides the first empirical evidence of beetle ecological succession and diversity on carrion in Mexican agro-pastoral landscapes. PMID:25447187

  8. Helicobacter pylori infection in patients with calcular cholecystitis: a hospital based study

    International Nuclear Information System (INIS)

    Background: Helicobacter pylori, a gram negative bacillus has been recognised as a public health problem and approximately half of the world population has H. pylori infection causes chronic gastritis, peptic ulcer disease and gastric malignancies. Objective of this study was to determine the frequency of H. pylori infection in patients of chronic calcular cholecystitis. Methods: This cross-sectional descriptive study was conducted at Liaquat University Hospital, Hyderabad, Pakistan from April 2010 to September 2010. All patients with history of gallstone presented with acute abdominal pain, dyspepsia, bloating and epigastric discomfort and diagnosed as calcular cholecystitis were further evaluated for the detection of H. pylori by serology and histopathology. Frequency and percentage of H. pylori infection in patients with calcular cholecystitis was calculated. Result: Total 100 patients of cholelithiasis underwent laparoscopic cholecystectomy were recruited. The pain in upper right part of the abdomen was observed in all 100 patients, fever in 75%, nausea and vomiting in 68%, loss of appetite in 45%, feeling of tiredness or weakness in 22%, headache in 38%, chills in 52%, backache in 58%, pain under the right shoulder in 45%, heartburn in 67%, belching in 54%, indigestion in 80%, dyspepsia in 90%, bloating in 88%, and epigastric discomfort in 85% patients. Eighty-two percent patients had family history of gallstones. The mean age of overall study population was 48.72 +- 8.78 years and mean age of H. pylori infected calcular cholecystitis patients was 47.98 +- 5.43 years in male and 48.76 +- 6.68 years in females. The H. pylori infection was identified in 55% patients with calcular cholecystitis, of which 32.7% were males and 67.3% were females (p=0.03, statistically significant). Majority of females (60%) had =40 U/ml antibody titre (p=0.917, non-significant). Conclusion: A possible relationship was identified between Helicobacter pylori and calcular

    Full Text Available Kevin W OldenDepartment of Medicine, St Joseph's Hospital and Medical Center, Phoenix, AZ, USAAbstract: Irritable bowel syndrome (IBS causes gastrointestinal symptoms such as abdominal pain, bloating, and bowel pattern abnormalities, which compromise patients' daily functioning. Common therapies address one or two IBS symptoms, while others offer wider symptom control, presumably by targeting pathophysiologic mechanisms of IBS. The aim of this targeted literature review was to capture clinical trial reports of agents receiving the highest recommendation (Grade 1 for treatment of IBS from the 2009 American College of Gastroenterology IBS Task Force, with an emphasis on diarrhea-predominant IBS. Literature searches in PubMed captured articles detailing randomized placebo-controlled trials in IBS/diarrhea-predominant IBS for agents receiving Grade I (strong 2009 American College of Gastroenterology IBS Task Force recommendations: tricyclic antidepressants, nonabsorbable antibiotics, and the 5-HT3 receptor antagonist alosetron. Studies specific for constipation-predominant IBS were excluded. Tricyclic antidepressants appear to improve global IBS symptoms but have variable effects on abdominal pain and uncertain tolerability; effects on stool consistency, frequency, and urgency were not adequately assessed. Nonabsorbable antibiotics show positive effects on global symptoms, abdominal pain, bloating, and stool consistency but may be most efficacious in patients with altered intestinal microbiota. Alosetron improves global symptoms and abdominal pain and normalizes bowel irregularities, including stool frequency, consistency, and fecal urgency. Both the nonabsorbable antibiotic rifaximin and the 5-HT3 receptor antagonist alosetron improve quality of life. Targeted therapies provide more complete relief of IBS symptoms than conventional agents. Familiarization with the quantity and quality of evidence of effectiveness can facilitate more individualized

  10. Temperature Impact on the Forage Quality of Two Wheat Cultivars with Contrasting Capacity to Accumulate Sugars

    Full Text Available Wheat is increasingly used as a dual-purpose crop (for forage and grain production worldwide. Plants encounter low temperatures in winter, which commonly results in sugar accumulation. High sugar levels might have a positive impact on forage digestibility, but may also lead to an increased risk of bloat. We hypothesized that cultivars with a lower capacity to accumulate sugars when grown under cold conditions may have a lower bloat risk than higher sugar-accumulating genotypes, without showing significantly lower forage digestibility. This possibility was studied using two wheat cultivars with contrasting sugar accumulation at low temperature. A series of experiments with contrasting temperatures were performed in controlled-temperature field enclosures (three experiments and growth chambers (two experiments. Plants were grown at either cool (8.1 °C–9.3 °C or warm (15.7 °C–16.5 °C conditions in field enclosures, and at either 5 °C or 25 °C in growth chambers. An additional treatment consisted of transferring plants from cool to warm conditions in the field enclosures and from 5 °C to 25 °C in the growth chambers. The plants in the field enclosure experiments were exposed to higher irradiances (i.e., 30%–100% than those in the growth chambers. Our results show that (i low temperatures led to an increased hemicellulose content, in parallel with sugar accumulation; (ii low temperatures produced negligible changes in in vitro dry matter digestibility while leading to a higher in vitro rumen gas production, especially in the higher sugar-accumulating cultivar; (iii transferring plants from cool to warm conditions led to a sharp decrease in in vitro rumen gas production in both cultivars; and (iv light intensity (in contrast to temperature appeared to have a lower impact on forage quality.

    Sebaceous gland diseases are a group of common dermatological diseases with multiple causes. To date, a systematic report of the risk factors for sebaceous gland diseases in adolescents has not been published. The aim of this study was to assess the prevalence and risk factors for certain sebaceous gland diseases (seborrhea, seborrheic dermatitis, acne, androgenetic alopecia and rosacea) and their relationship to gastrointestinal dysfunction in adolescents. From August-October, 2002-2005, a questionnaire survey was carried out to obtain epidemiological data about sebaceous gland diseases. Using random cluster sampling, 13 215 Han adolescents aged 12-20 years were recruited from four countries or districts (Macau; Guangzhou, China; Malaysia; and Indonesia). The statistical software SPSS ver. 13.0 was used to analyze the data. The prevalence of seborrhea, seborrheic dermatitis, acne, androgenetic alopecia and rosacea was 28.27%, 10.17%, 51.03%, 1.65% and 0.97%, respectively. Based on multivariate logistic regression analysis, the risk factors for sebaceous gland diseases included: age; duration of local residency; halitosis; gastric reflux; abdominal bloating; constipation; sweet food; spicy food; family history of acne; late night sleeping on a daily basis; excessive axillary, body and facial hair; excessive periareolar hair; and anxiety. There was a statistically significant difference in the prevalence of gastrointestinal symptoms (halitosis; gastric reflux; abdominal bloating; constipation) between patients with and without sebaceous gland diseases (chi(2) = 150.743; P = 0.000). Gastrointestinal dysfunction is an important risk factor for diseases of the sebaceous glands and is correlated with their occurrence and development. PMID:18837699

    Mass accretion onto (proto-)stars at high accretion rates \\dot{M}_* > 10^{-4} M_{⊙} yr^{-1} is expected in massive star formation. We study the evolution of massive protostars at such high rates by numerically solving the stellar structure equations. In this paper, we examine the evolution via disk accretion. We consider a limiting case of "cold" disk accretion, whereby most of the stellar photosphere can radiate freely with negligible backwarming from the accretion flow, and the accreting material settles onto the star with the same specific entropy as the photosphere. We compare our results to the calculated evolution via spherically symmetric accretion, the opposite limit, whereby the material accreting onto the star contains the entropy produced in the accretion shock front. We examine how different accretion geometries affect the evolution of massive protostars. For cold disk accretion at 10-3 M sun yr-1, the radius of a protostar is initially small, R *sime a few R sun. After several solar masses have accreted, the protostar begins to bloat up and for M * ~= 10 M sun the stellar radius attains its maximum of 30-400 R sun. The large radius ~100 R sun is also a feature of spherically symmetric accretion at the same accreted mass and accretion rate. Hence, expansion to a large radius is a robust feature of accreting massive protostars. At later times, the protostar eventually begins to contract and reaches the zero-age main sequence (ZAMS) for M * ~= 30 M sun, independent of the accretion geometry. For accretion rates exceeding several 10-3 M sun yr-1, the protostar never contracts to the ZAMS. The very large radius of several hundreds R sun results in the low effective temperature and low UV luminosity of the protostar. Such bloated protostars could well explain the existence of bright high-mass protostellar objects, which lack detectable H II regions.

    Full Text Available Abstract Introduction The hide beetle Dermestes maculatus (Coleoptera: Dermestidae feeds as an adult and larva on decomposing animal remains and can also be found on human corpses. Therefore, forensic entomological questions with regard to when and how the first receptive females appear on carcasses are important, as the developmental stages of their larvae can be used to calculate the post-mortem interval. To date, we know that freshly emerged males respond to the cadaver odour of post-bloated carcasses (approximately 9 days after death at Tmean = 27°C, being attracted by benzyl butyrate. This component occurs at its highest concentration at this stage of decay. The aim of our study was to determine the principle of attraction of virgin females to the feeding and breeding substrate. For this purpose, we tested the response of these females to headspace samples of piglet cadavers and male sex pheromones [(Z9-unsaturated fatty acid isopropyl esters] in a Y-olfactometer. Because we expected that such an odour combination is of importance for virgin female attraction, we tested the following two questions: 1 Are virgin female hide beetles attracted by a combination of cadaver odour and male sex pheromones? 2 During which decomposition stage do the first virgin females respond to cadaver odour when combined with male sex pheromones? Results We found that young virgin females were attracted to the cadaver by a combination of cadaver odour and male sex pheromones. Neither cadaver odour alone nor male sex pheromones alone was significantly more attractive than a solvent control. Our results also gave a weak indication that the first young virgin females respond as early as the post-bloating stage to its associated decomposition odour when combined with male sex pheromones. Conclusions Our results indicate that freshly emerged males possibly respond to cadaver odour and visit carcasses before virgin females. Being attracted to cadavers when male sex

    The special patterns of the slow wave activity in irrittable bowel syndrome by means of surface electromyography were examined and the effect of pinaverium bromide on the symptoms and on the colonic motility in this disease was estimated. Twenty two patients with irritable bowel syndrome and 7 healthy controls were selected to the study. The clinical symptoms were abdominal pain and bloating in all patients, constipation in 9, and diarrhoea in 6 cases. Surface electromyography was carried out before and on the 14th day of the treatment with pinaverium bromide (50 mg t. i. d). The colonic motility was analysed in a 2 hour fasting and a 2 hour postprandial period following a standard (800 kCal) meal. The slow wave frequency of 0.01-0.04 Hz were selected and analysed. The mean frequency of activity peaks (n/10 min) and power-index (area under curve, microV 10 min) were measured. For statistical analysis Student's t-test was applied. Electromyogram of patients with irritable bowel syndrome showed a significant increase of the measured colonic motility parameters both in fasting and postprandial states. Fourteen days of pinaverium bromide treatment was able to significantly reduce the intensity of the colonic motor activity. Administration of pinaverium bromide completely released in 6 and significantly improved the abdominal pain in other 12 patients, while the bloating disappeared in 12 and was significantly improved in 5 from 22 patients. Pinaverium bromide was able to normalise the stool frequency: the weekly number of stools was decreased from 16 to 7 in the patients complaining diarrhoea ant it was increased from 2 to 6 in the patients with constipation.

    "Lactose intolerance (LI)" is considered a common problem in Asians, and in many parts of the world. Its prevalence and age of manifestation varies between by Asian country, for possible genetic or cultural reasons. Studies in Indonesian children 3-15 years old (y) are available within the past two decades, using a pure lactose tolerance test. The prevalences of lactose malabsorption (LM) in pre-elementary (3-5 y), elementary (6-11 y), and junior high (12-14 y) school-children were 21.3%, 57.8%, and 73%, respectively. An increasing trend for LM prevalence was seen within the pre-elementary group, from 9.1% at 3 y to 28.6% at 5 y. The most frequent symptoms of LI in junior high school (JHS) group were abdominal pain (64.1%), abdominal distention (22.6%), nausea (15.1%), flatulence (5.7%), and diarrhea (1.9%), mostly within one hour of lactose ingestion. In children with regular and irregular milk drinking, LM occurred in 81.2% and 69.6%; LI was found in 56.2% and 52.1%, respectively. Most JHS children with dairy-associated recurrent abdominal pain (RAP) symptoms proved to be malabsorbers. Dairy products most related to RAP were milk and yogurt. LI was found in 81% of RAP children with abdominal pain most frequently, followed by nausea, bloating, diarrhea, borborygmi, and flatulence. Symp-tom onset occurred 30 minutes after lactose ingestion, especially nausea, bloating, and abdominal pain. In RAP children LI symptoms mostly found in breath hydrogen concentration>20 ppm. More LI symptoms were found in lactose malabsorbers, but symptoms were mild and generally disappeared in 7 hours, and in most by 15 hours. PMID:26715082

    Full Text Available Context : Excess prevalence of irritable bowel syndrome in asthma has been reported, suggesting a link between these two conditions. Aims: To investigate the association between irritable bowel syndrome (IBS and asthma, and explore the symptoms of IBS among asthma patients in Kuwait. Settings and Design: Case control study. Methods: In a tertiary center, for allergy and asthma, 138 patients aged 20-65 years, with asthma, diagnosed clinically and by spirometry,were compared with 145 healthy, non-asthmatic controls matched for age, gender and nationality. Cases and controls completed a self-administered questionnaire of irritable bowel syndrome diagnosis (ROME II criteria. Statistical Analysis Used: The data were analyzed using SPSS software, and proportions were tested with Chi-square or Fisher′s test. Odds ratio (OR with 95% Confidence Interval (CI were calculated to identify the associated risk factors. The demographic variables were selected for logistic regression analysis. Results : A significantly large proportion (39.13% of asthmatics had IBS as compared to 7.93% controls (P < 0.001. A higher proportion of females with IBS were observed in cases and controls (74%, 61.54%. IBS was seen in 87% cases using inhalers, and in 13% with additional oral theophylline (P < 0.001. As many as 66.6% cases, had IBS with relatively short duration of asthma (1-5 years, P < 000. Predominant symptoms of IBS in asthmatics were abdominal discomfort or distension (64.8% vs. 11.5%, (P < 0.000, OR = 14.1; 95%CI: 3.748-53.209, bloated feeling of abdomen (74.1% vs. 34.62% (P < 0.001, OR = 5.38; 95%CI:1.96-14.84, increased frequency of stools (63%, P < 0.006. Conclusions: Irritable bowel syndrome in asthmatics was significantly high, more in the female asthmatics. Abdominal discomfort, persistent bloated feeling, increased frequency of passing stools were the most common IBS symptoms observed.

Commonly, intolerant patients are advised by physicians to avoid the offending foods (dairy foods, cereals, beans, etc. This food-limiting option, however, has possible nutritional risks. We have therefore evaluated the impact of using pure, enteric-coated α- plus ß-galactosidase on gut symptoms in intolerant subjects instead of avoidance of the offending foods. Methods: Sixteen subjects intolerant to lactose and/or complex carbohydrates were enrolled and evaluated in terms of gut symptoms with 1 uncontrolled diet, 2 diet devoid of offending foods, and 3 uncontrolled diet along with pure, enteric-coated α- and ß-galactosidase (DDM Galactosidase®. Results: Even with the uncontrolled diet, intolerant subjects treated with DDM Galactosidase® exhibited reduced gut symptoms (bloating, flatulence, diarrhea, and constipation significantly better than the control treatment as well as having a diet devoid of offending foods. Conclusion: DDM Galactosidase® is a valid and safe optional treatment to counteract lactose and complex carbohydrate intolerance in subjects who prefer not to avoid, at least partially, offending foods.

    Objective Patients with generalized autoimmune dysautonomia may also present with gastroparesis. Immune dysfunction in such patients can be evaluated using antibodies to glutamic acid decarboxylase (GAD) and full thickness biopsy of stomach. In this study, we utilize immunotherapy for treatment of drug and Gastric Electrical Stimulation (GES) resistant gastroparetic patients with evidence of neuroinflammation on full thickness gastric biopsy and had positive GAD65 autoantibodies. Material and methods We conducted a retrospective chart review of 11 female patients with drug and device resistant gastroparesis. Patients were treated for a total of 8–12 weeks with either intravenous immunoglobulin (IVIg), or combined mycophenolate mofetil (MM) and methylprednisolone, or only MM. Patients were excluded if they had previous side effects from steroid therapy, low scores on dual-energy X-ray absorptiometry (DEXA) scan results, immune-compromised conditions with infections like tuberculosis and zoster. Symptoms of nausea, vomiting, abdominal pain, early satiety/anorexia, bloating and total symptom score (TSS) as reported by the patients were recorded before and after the treatment at a follow up visit 2 to 16 weeks after initiation of therapy. Results Maximum symptom improvement was seen in patients treated with IVIg (67%). 6 patients (55%) had improvement in vomiting, whereas 5 patients (45%) had improvements in nausea, abdominal pain and bloating. Conclusions Immunomodulatory therapy shows positive outcomes in improving vomiting symptom in some gastroparetic patients who have coexisting positive autoimmune profiles. This preliminary data suggests the need for further investigations in immunotherapy targeted to patients with gastroparetic symptoms refractory to approved drug and device therapies. PMID:27014566

    Full Text Available Abstract Background Small intestinal bacterial overgrowth (SIBO is a condition in which excessive levels of bacteria, mainly the colonic-type species are present in the small intestine. Recent data suggest that SIBO may contribute to the pathophysiology of Irritable bowel syndrome (IBS. The purpose of this study was to identify potential predictors of SIBO in patients with IBS. Methods Adults with IBS based on Rome II criteria who had predominance of bloating and flatulence underwent a glucose breath test (GBT to determine the presence of SIBO. Breath samples were obtained at baseline and at 30, 45, 60, 75 and 90 minutes after ingestion of 50 g of glucose dissolved in 150 mL of water. Results of the glucose breath test, which measures hydrogen and methane levels in the breath, were considered positive for SIBO if 1 the hydrogen or methane peak was >20 ppm when the baseline was Results Ninety-eight patients were identified who underwent a GBT (mean age, 49 y; 78% female. Thirty-five patients (36% had a positive GBT result suggestive of SIBO. A positive GBT result was more likely in patients >55 years of age (odds ratio [OR], 3.6; 95% confidence interval [CI], 1.4-9.0 and in females (OR, 4.0; 95% CI, 1.1-14.5. Hydrogen was detected more frequently in patients with diarrhea-predominant IBS (OR, 8; 95% CI, 1.4-45, and methane was the main gas detected in patients with constipation-predominant IBS (OR, 8; 95% CI, 1.3-44. There was no significant correlation between the presence of SIBO and the predominant bowel pattern or concurrent use of tegaserod, proton pump inhibitors, or opiate analgesics. Conclusions Small intestinal bacterial overgrowth was present in a sizeable percentage of patients with IBS with predominance of bloating and flatulence. Older age and female sex were predictors of SIBO in patients with IBS. Identification of possible predictors of SIBO in patients with IBS could aid in the development of successful treatment plans.

    Full Text Available Abstract Background Dietary nucleotide supplementation has been shown to have important effects on the growth and development of cells which have a rapid turnover such as those in the immune system and the gastrointestinal tract. Work with infants has shown that the incidence and duration of diarrhoea is lower when nucleotide supplementation is given, and animal work shows that villi height and crypt depth in the intestine is increased as a result of dietary nucleotides. Dietary nucleotides may be semi-essential under conditions of ill-health, poor diet or stress. Since people with Irritable Bowel Syndrome tend to fulfil these conditions, we tested the hypothesis that symptoms would be improved with dietary nucleotide supplementation. Methods Thirty-seven people with a diagnosis of Irritable Bowel gave daily symptom severity ratings for abdominal pain, diarrhoea, urgency to have a bowel movement, incomplete feeling of evacuation after a bowel movement, bloating, flatulence and constipation for 28 days (baseline. They were then assigned to either placebo (56 days followed by experimental (56 days or the reverse. There was a four week washout period before crossover. During the placebo and experimental conditions participants took one 500 mg capsule three times a day; in the experimental condition the capsule contained the nutroceutical substances. Symptom severity ratings and psychological measures (anxiety, depression, illness intrusiveness and general health were obtained and analysed by repeated measures ANOVAs. Results Symptom severity for all symptoms (except constipation were in the expected direction of baseline>placebo>experimental condition. Symptom improvement was in the range 4 – 6%. A feeling of incomplete evacuation and abdominal pain showed the most improvement. The differences between conditions for diarrhoea, bloating and flatulence were not significant at the p Conclusion Dietary nucleotide supplementation improves some of the

  4. A THIRD HOT WHITE DWARF COMPANION DETECTED BY KEPLER

    International Nuclear Information System (INIS)

    We have found a system listed in the Kepler Binary Catalog (Porb = 3.273 days) that we have determined is comprised of a low-mass, thermally bloated, hot white dwarf orbiting an A star of about 2.3 Msun. In this work, we designate the object, KIC 10657664, simply as 'KHWD3' (Kepler Hot White Dwarf 3). We use the transit depth of ∼0.66%, the eclipse depth of ∼1.9%, and regular smooth periodic variations at the orbital frequency and twice the orbital frequency to analyze the system parameters. The smooth periodic variations are identified with the classical ellipsoidal light variation (ELV) and illumination (ILL) effects, and the newly utilized Doppler boosting (DB) effect. Given the measured values of R/a and inclination angle of the binary, both the ELV and DB effects are mostly sensitive to the mass ratio, q = M2/M1, of the binary. The two effects yield values of q which are somewhat inconsistent-presumably due to unidentified systematic effects-but which nonetheless provide a quite useful set of possibilities for the mass of the white dwarf (either 0.26 ± 0.04 Msun or 0.37 ± 0.08 Msun). All of the other system parameters are determined fairly robustly. In particular, we show that the white dwarf has a radius of 0.15 ± 0.01 Rsun, which is extremely bloated over the radius it would have as a fully degenerate object, and an effective temperature Teff≅14,500 K. Binary evolution scenarios and models for this system are discussed. We suggest that the progenitor binary was comprised of a primary of mass ∼2.2 Msun (the progenitor of the current hot white dwarf) and a secondary of mass ∼1.4 Msun (the progenitor of the current A star in the system). We compare this new system with three other white dwarfs in binaries that likely were formed via stable Roche-lobe overflow (KOI-74, KOI-81, and the inner Regulus binary).

    The effects of a dietary challenge to induce digestive upsets and supplementation with yeast culture on rumen microbial fermentation were studied using 12 Holstein heifers (277 +/- 28 kg of BW) fitted with a ruminal cannula, in a crossover design with 2 periods of 5 wk. In each period, after 3 wk of adaptation to a 100% forage diet, the dietary challenge consisted of increasing the amount of grain at a rate of 2.5 kg/d (as-fed basis) over a period of 4 d, until a 10:90 forage:concentrate diet was reached, and then it was maintained for 10 d. Between periods, animals were fed again the 100% forage diet without any treatment for 1 wk as a wash-out period. Treatments started the first day of each period, and they were a control diet (CL) or the same diet with addition of yeast culture (YC, Diamond V XPCLS). Digestive upsets were determined by visual observation of bloat or by a reduction in feed intake (as-fed basis) of 50% or more compared with intake on the previous day. Feed intake was determined daily at 24-h intervals during the adaptation period and daily at 2, 6, and 12 h postfeeding during the dietary challenge. Ruminal liquid samples were collected daily during the dietary challenge to determine ruminal pH at 0, 3, 6, and 12 h postfeeding, and total and individual VFA, lactic acid, ammonia-N, and rumen fluid viscosity at 0 and 6 h postfeeding. The 16s rRNA gene copies of Streptococcus bovis and Megasphaera elsdenii were determined by quantitative PCR. Foam height and strength of the rumen fluid were also determined the day after the digestive upset to evaluate potential foam production. A total of 20 cases (83.3%) of digestive upsets were recorded in both periods during the dietary challenge, all diagnosed due to a reduction in feed intake. Rumen fermentation profile at 0 h on the digestive upset day was characterized by low ruminal pH, which remained under 6.0 for 18 h, accompanied by elevated total VFA concentration and, in some cases, by elevated lactate

    The lightweight keramzite was prepared using sewage sludge from municipal sewage treatment plant with the gangue sludge and fly ash as aids.The fabrication process simulated the practical manufacturing in the factory, and the properties of the kerarnzite samples were characterized. The results indicated that bloating keramzite could be prepared at 1 040 ℃ with short stay time. Although the addition of 10% sludge didn' t benefit bloating but it improved the sintering behavior of the sample and therefore enhanced the cylindrical compress strength. When the green sample comprised of 50% sewage sludge, 25% fly ash, and 25% gangue sludge, the prepared keramzite had a granule density of 0.76 g/cm3, a weight loss in hydrochloric acid of 1.86%, and a cylindrical compress strength of 5.2 MPa, respectively.%以城市污水处理厂的湿态剩余污泥为主原料,辅以集料尾泥(主要成分为粘土)和粉煤灰配料,在模拟实际加工工况的条件下制备烧结污泥陶粒样品,对其性能进行表征.研究结果表明以湿态污泥为主原料,经1 040℃的短时烧结可获得烧胀陶粒.还发现少量(质量分数为10%)污泥的加入虽不起烧胀作用,但有明显的助烧结作用,相对于无污泥样品,陶粒样品的筒压强度有显著提高.当陶粒坯体中污泥质量分数为50%、粉煤灰质量分数为25%、集料尾泥质量分数为25%时,在1 040℃烧结后的污泥陶粒样品具有较为理想的轻集料性能:堆积密度为0.76g/cm3;盐酸可溶率为1.86%;筒压强度为5.2MPa.

    BACKGROUND Celiac disease presents with a wide spectrum of symptoms. This study clarifies different aspects of celiac disease along with the most common patterns of celiac presentation in Khuzestan Province, Iran. METHODS Patients' information was obtained by evaluation of their files from the archives of the Khuzestan Celiac Society and records at gastroenterologists' offices in this province. RESULTS Overall, there were 103 (40 males, 63 females) patients included in this study. Patients' mean ages were 33 ± 11 years (males) and 31.6 ± 11.7 years (females). In terms of geographic distribution, 54.1% resided in the center of the province followed by 26.5% who were residents of the northern area. The rate of employment among men was 70.6% whereas it was 8.3% for women. In terms of education, 21.9% of men and 33.3% of women had academic educations. The rate of matrimony was 80.6% (n=29) for men, 65.4% (n=38) for women and 3.4% (n=2) who were divorced. Mean height was 164 ± 14 cm in men and 157.5 ± 10 cm in women. Mean BMI at the time of presentation was 22.7 in men and 22.6 in women. The most common gastrointestinal (GI) complaints in male patients were diarrhea (35%), reflux (20%), bloating (17.5%), abdominal pain (15%), vomiting (15%) and constipation (7.5%). Female patients experienced diarrhea (49.2%), abdominal pain (31.7%), bloating (31.7%), vomiting (19%), constipation(9.5%) and reflux (7.9%). The most common concomitant non-GI disorders among male patients were anemia (17.1%), thyroid disease (14.3%), and weight loss (14.3%); women experienced anemia (33.9%), thyroid disease (12.5%), and weight loss (7.1%). Approximately half of the patients exhibited symptoms for more than five years prior to diagnosis and 90% were diagnosed by gastroenterologists. Of these, 43% had normal endoscopy results. The most common serologic markers were anti-TTG (69.9%), anti-EMA (27.7%). CONCLUSION Physicians, prior to attributing patients' symptoms to irritable bowel

    The present studies explored whether faecal retention in the colon is a causative factor in functional bowel disease, appendicitis, and haemorrhoids. Faecal retention was characterized by colon transit time (CTT) after radio-opaque marker ingestion and estimation of faecal loading on abdominal radiographs at 48 h and 96 h. Specific hypotheses were tested in patients (n = 251 plus 281) and in healthy random controls (n = 44). A questionnaire was completed for each patient, covering abdominal and anorectal symptoms and without a priori grouping. Patients with functional bowel disorders, predominantly women, had a significantly increased CTT and faecal load compared to controls. The CTT was significantly and positively correlated with segmental and total faecal loading. The faecal load was equal at 48 h and 96 h, mirroring the presence of permanent faecal reservoirs. In these first clinical studies to correlate bowel symptoms with CTT and colon faecal loading, abdominal bloating was significantly correlated with faecal loading in the right colon, total faecal load, and CTT. Abdominal pain was significantly and positively correlated to distal faecal loading and significantly associated with bloating. A new phenomenon with a high faecal load and a normal CTT was observed in a subset of patients (n = 90), proving faecal retention as hidden constipation. The CTT and faecal load were significantly higher in the right-side compared to the left and distal segments. Within the control group of healthy persons, the right-sided faecal load was significantly greater than the left and distal load. The CTT and faecal load significantly positively correlated with a palpable mass in the left iliac fossa and meteorism. Cluster analysis revealed that CTT and faecal load positively correlated with a symptom factor consisting of bloating, proctalgia and infrequent defecation of solid faeces. On the other hand, CTT and faecal load negatively correlated with a symptom factor comprising

    We report the discovery of four new short-period eclipsing systems in the Kepler light curves, consisting of an A-star primary and a low-mass white-dwarf (WD) secondary (dA+WD) - KIC 4169521, KOI-3818, KIC 2851474 and KIC 9285587. These add to the 6 Kepler, and 19 non-Kepler, previously known short-period eclipsing dA+WD binaries.The discoveries were made through searching the light curves of bright Kepler stars for BEaming, Ellipsoidal and Reflection (BEER) modulations that are consistent with a compact companion, using the BEER search algorithm. This was followed by inspection of the search top hits, looking for eclipsing systems with a secondary eclipse deeper than the primary one, as expected for a WD that is hotter than the primary star. Follow-up spectroscopic radial-velocity (RV) observations confirmed the binarity of the systems. We derive the systems' parameters through analyses of the light curves' eclipses and phase modulations, combined with RV orbital solutions and stellar evolution models.The four systems' orbital periods of 1.17-3.82 days and WD masses of 0.19-0.22 Msun are similar to those reported for the previously known systems. These values are consistent with evolution models of such systems, that undergo a stable mass transfer from the WD progenitor to the current A star.For KIC 4169521 we derive a bloated WD radius of 0.09 Rsun that is well within the WD radius range of 0.04-0.43 Rsun of the known systems. For the remaining three systems we report WD radii of 0.026-0.035 Rsun, the smallest WD radii derived so far for short-period eclipsing dA+WD binaries.As suggested before, the previously known systems, together with KIC 4169521, all with hot and bloated WD secondaries, represent young systems probably at a proto-WD, or initial WD cooling track stage. The other three new systems - KOI-3818, KIC 2851474, and KIC 9285587, are probably positioned further along the WD cooling track, and extend the known population to older systems with cooler

  10. Intestinal obstruction due to Vasconcellea seeds: Report of three cases and literature review

    2015-07-01

    Full Text Available Vasconcellea spp., is a species of Andean papaya commonly cultivated in rural communities close to Medellín, Colombia. Due to the pleasant and sweet flavor of its fruits, children frequently ingest its seeds accidentally. After ingestion, the seeds are engaged in the colonic lumen and block the exit of stools, causing pain and bloating, and promoting bacterial translocation. Diagnosis is based on clinical history and rectal examination. Treatment depends on the degree of local and systemic involvement and includes disimpaction of rectal contents under general anesthesia and colonic washes with 0.9% saline solution. In severe cases derivative colostomy has been required. In the literature there are no reports of intestinal obstruction due to Vasconcellea seeds, possibly because it has been mistaken for seeds of the genus Carica. In this article, three cases treated at pediatric services in Medellín, Colombia, in 2012 and 2013 are described. We note that this is a rarely suspected disease, leading to late diagnosis and potential catastrophic consequences. It is important to educate people to prevent the ingestion of the seeds.

    Lignite coal fly ash from the 'Nikola Tesla' power plant in Yugoslavia has been characterised, milled, compacted and sintered to form monolithic ceramic materials. The effect of firing at temperatures between 1130 and 1190{sup o}C on the density, water accessible porosity, mineralogy and microstructure of sintered samples is reported. This class C fly ash has an initial average particle size of 82 {mu}m and contains siliceous glass together with the crystalline phases quartz, anorthite, gehlenite, hematite and mullite. Milling the ash to an average particle size of 5.6 m, compacting and firing at 1170{sup o}C for 1 h produces materials with densities similar to clay-based ceramics that exhibit low water absorption. Sintering reduces the amount of glass, quartz, gehlenite and anhydrite, but increases formation of anorthite, mullite, hematite and cristobalite. SEM confirms the formation of a dense ceramic at 1170{sup o}C and indicates that pyroplastic effects cause pore formation and bloating at 1190{sup o}C. 23 refs., 6 figs., 2 tabs.

    Nowadays,we are heading towards integrating hundreds to thousands of cores on a single chip.However,traditional system software and middleware are not well suited to manage and provide services at such large scale.To improve the scalability and adaptability of operating system and middleware services on future many-core platform,we propose the pinned OS/services.By porting each OS and runtime system (middleware) service to a separate core (special hardware acceleration),we expect to achieve maximal performance gain and energy efficiency in many-core environments.As a case study,we target on XML (Extensible Markup Language),the commonly used data transfer/store standard in the world.We have successfully implemented and evaluated the design of porting XML parsing service onto Intel 48-core Single-Chip Cloud Computer (SCC) platform.The results show that it can provide considerable energy saving.However,we also identified heavy performance penalties introduced from memory side,making the parsing service bloated.Hence,as a further step,we propose the memory-side hardware accelerator for XML parsing.With specified hardware design,we can further enhance the performance gain and energy efficiency,where the performance can be improved by 20% with 12.27%energy reduction.

    Context The feeling of abdominal fullness, bloating, and movement of gas in the abdomen is a very uncomfortable sensation termed flatulence. Since flatulence is one of the most common gastrointestinal symptoms that is bothersome to patients, it is important to identify effective methods to resolve this issue. In modern medicine, management of flatulence is often not satisfactory. On the other hand, traditional systems of medicine can be considered good potential sources to find new approaches for preventing and treating flatulence. The aim of this study is to review flatulence treatments from a traditional Persian medicine (TPM) viewpoint. Evidence Acquisition In this study, the reasons for flatulence and methods for its prevention and treatment are reviewed in traditional Persian medicine (TPM) texts and then related with evidence from modern medicine by searching in databases, including PubMed, Scopus, Google Scholar, and IranMedex. Results From a traditional Persian scholar viewpoint, one of the most important causes of flatulence is an incorrect manner of eating; valuable advice to correct bad eating habits will be illustrated. In addition, traditional practitioners describe some herbs and vegetables as well as herbal compounds that are effective food additives to relieve flatulence. The anti-flatulent effect of most of these herbs has been experimentally verified using modern medicine. Conclusions Attention to TPM can lead to the identification of new preventive and curative approaches to avoid and treat flatulence. In addition, Persian viewpoints from the medieval era regarding flatulence are historically important.

The subjects presented frequent central nervous system (CNS symptoms: headache in three patients, somnolence in one, electroencephalogram aspecific alterations in three (in two of them with previous seizures, leptomeningeal cyst in one, intracranial calcification in one, cerebral gliosis in two. After a gluten-free diet, all intestinal and clinical CNS features remitted, but re-appeared after gluten reintroduction. On the basis of the neurological signs, the authors stress the relevance of immune innate system in the pathogenesis of these cases with possible subsequent evolution on immune adaptive system involvement.

    Thyroid storm is a rare but life-threatening condition, which can be induced by many critical diseases. We reported a 40-year-old woman with thyroid goiter manifesting with acute sepsis-induced hyperthyroidism. She mainly presented with abdominal bloating, diarrhea, lower limbs edema and exertional dyspnea. The lactate was 9.5 mmol/L and procalcitonin was 3.8 ng/mL, suggesting acute sepsis. The thyroid echo showed bilateral thyroid goiter. Relevant data included a thyroid-stimulating hormone level of 0.03 mIU/mL;free tetraiodothyronine, 5.67 ng/dL;thyroid-stimulating hormone receptor antibody, 76.9%(normal range, < 14%); and antimicrosomal antibody titer, 1:102 400 (normal range,<1:100), suggesting toxic goiter with thyroid storm. Piperacillin/tazobactam, methimazole and Lugol's iodine achieved a good outcome. The symptoms of early sepsis and those of thyroid storm could be similar. Therefore, a careful history taking, a thorough physical examination and a high degree of suspicion could make early diagnosis and appropriate treatment.

    We present new ground-based, multi-colour, broad-band photometric measurements of the physical parameters, transmission and emission spectra of the transiting extrasolar planet WASP-19b. The measurements are based on observations of 8 transits and four occultations using the 1.5m Danish Telescope, 14 transits at the PEST observatory, and 1 transit observed simultaneously through four optical and three near-infrared filters, using the GROND instrument on the ESO 2.2m telescope. We use these new data to measure refined physical parameters for the system. We find the planet to be more bloated and the system to be twice as old as initially thought. We also used published and archived datasets to study the transit timings, which do not depart from a linear ephemeris. We detected an anomaly in the GROND transit light curve which is compatible with a spot on the photosphere of the parent star. The starspot position, size, spot contrast and temperature were established. Using our new and published measurements, we as...

    2010-01-01

    Full Text Available Aim of the current study was to evaluate the clinical/health status of veal calves in 3 farms that adopt large group housing and automatic feeding stations in Italy. Visits were scheduled in three phases of the rearing cycle (early, middle, and end. Results showed a high incidence of coughing, skin infection and bloated rumen particularly in the middle phase while cross-sucking signs were present at the early stage when calves’ nibbling proclivity is still high. Throughout the rearing cycle, the frequency of bursitis increased reaching 53% of calves at the end. The percentage of calves with a poorer body condition than the mid-range of the batch raised gradually as well, likely due to the non-proportioned teat/calves ratio that increases competition for feed and reduces milk intake of the low ranking animals. The remarked growth differences among pen-mates and the mortality rate close to 7% showed by the use of automatic feeding devices for milk delivery seem not compensating the lower labour demand, therefore its sustainability at the present status is doubtful both for the veal calves’ welfare and the farm incomes.

    Ovarian hyperstimulation syndrome (OHSS) is a well known but poorly understood iatrogenic complication of superovulation. Spontaneous OHSS has been reported with pregnancy, polycystic ovary syndrome, primary hypothyroidism and pituitary adenoma. Only a few cases of massive ovarian enlargement in non-pregnant women with primary hypothyroidism have been reported in the English literature. A definitive pathophysiology remains uncertain, although several postulations were proposed. A 23-year-old nulliparous woman presented with transient bloating of her abdomen associated with menstruation for the last four cycles. She had nausea, headache, faintness, galactorrhoea and clinical signs and symptoms of hypothyroidism (swelling in the hands and feet, cold intolerance, decreased activity, excessive sleepiness, loss of hair and dry skin) for 6 months. Thyroid stimulating hormone and serum prolactin levels were highly elevated (> 100 μg/l and 4,095 μg/l, respectively) and free thyroxine level was low. Abdominal ultrasound showed bilateral multiple thin-walled ovarian cysts. Contrast enhanced CT of brain showed a pituitary macroadenoma. Treatment with levothyroxine was started and showed marked clinical improvement with return to normal menstruation within 4 months. Serial ultrasound showed gradual regression of the ovarian cysts within 6 months. Serum prolactin level was gradually diminished. Awareness that ovarian and pituitary enlargement may be associated with severe hypothyroidism which can be managed successfully, will spare patients dangerous and unnecessary operative intervention for ovarian cysts or pituitary adenoma.

    Full Text Available In Colombia, mainly classic forensic medicine methods were used to clarify crimes until 2004. However, other disciplines, including forensic entomology, started to be considered only after the New Accusatory System introduction in Bogotá and the Coffee Region in 2005. In order to provide tools for obtaining evidentiary material elements in judicial trials, it is presented here the succession of insects throughout the decomposition process of an exposed carcass of Sus scrofa Linnaeus 1758 (Suidae and the Occurrence Matrix of colonizing species. This process was evaluated under ambient conditions in the Andean rural area of the city of Pereira, in the Mundo Nuevo district, located in a pre-montane Wet Forest area, from October to November 2006. A sampling period of 27 days and 3198 individuals were collected. We found these colonizing species in the following stages of decomposition: Lucilia eximia (Wiedemann, 1819 fresh; Hemilucilia semidiaphana (Rondani, 1850, Oxelytrum discicolle (Brullé, 1840, and Cochliomyia macellaria (Fabricius 1775 bloated; Chrysomya albiceps (Wiedemann 1819, Compsomyiops verena (Walker, 1849, Ophyra aenescens (Wiedemann, 1830 and Musca domestica Linnaeus, 1758 active; Fannia sp. advanced and Stearibia nigriceps (Meigen, 1826 remains.

    A 38-year-old woman with history of prior adrenalectomy for Cushing's syndrome presented with intermittent right lower quadrant (RLQ) abdominal pain, nausea, bloating, and non-bloody diarrhea for 2 months. Symptoms were not related to her menstrual periods. Examination revealed only an ill-defined mass in the RLQ. Investigations for infectious causes, inflammatory bowel disease, and carcinoid tumor were negative. Computed tomography (CT) demonstrated a terminal ileal mass with mesenteric stranding and dilatation of the proximal bowel. At laparotomy, a fibrotic, terminal ileal mass with matted adhesions involving the mesentery and retroperitoneum was resected. Histopathological examination identified multiple foci of endometriosis extending from the serosal surface into the mucosa of the terminal ileum. Immunostaining revealed E- and P-cadherin, but not N-cadherin immuno-positivity. Mucosal involvement without cyclical menstrual symptoms and intestinal obstruction is an unusual presentation of intestinal endometriosis. Although the mechanism of endometriosis is not clear, the role of cell adhesion molecules such as cadherins has received attention. Increased expression of E- and P-cadherin and decreased N-cadherin expression in our patient demonstrates differential expression of these cadherins in endometriotic tissue. Future studies may investigate patterns of differential expression of these cadherins in a series of cases to elucidate the mechanisms of migration of endometriotic tissue. PMID:17390177

    Full Text Available Adult midgut volvulus is a challenging diagnosis because of its low incidence and nonspecific symptoms. Diagnostic delay and long-term complaints are frequent in this clinical scenario. We reported a patient referred to our diagnostic imaging unit with intermittent abdominal pain, bloating and episodic vomiting for several years. He underwent barium gastrointestinal transit and abdominal ultrasound, which revealed severe gastric dilatation, food retention and slow transit until a depressed duodenojejunal flexure, with malrotation of the midgut and jejunal loops being located in the right upper quadrant. Computed tomography angiography was performed, showing rotation of the small intestine around the mesentery root, suggestive of midgut malrotation. In addition, an abnormal twisted disposition of superior mesenteric artery with corkscrew appearance was seen, shaping the pole-barber sign which was evident in volume rendering three-dimensional reconstructions. The patient underwent scheduled surgical treatment without any complication and had good outcome after hospital discharge and follow-up. Computed tomography plays an important role in evaluation of adult midgut volvulus. In addition, angiographic reconstructions can help us to assess the anatomic disposition of mesenteric vascular supply. Both of these assessments are useful in preoperative management.

    2011-01-15

    Tannins (hydrolysable and condensed tannin) are polyphenolic polymers of relatively high molecular weight with the capacity to form complexes mainly with proteins due to the presence of a large number of phenolic hydroxyl groups. They are widely distributed in nutritionally important forage trees, shrubs and legumes, cereals and grains, which are considered as anti-nutritional compounds due to their adverse effects on intake and animal performance. However, tannins have been recognised to modulate rumen fermentation favourably such as reducing protein degradation in the rumen, prevention of bloat, inhibition of methanogenesis and increasing conjugated linoleic acid concentrations in ruminant-derived foods. The inclusion of tannins in diets has been shown to improve body weight and wool growth, milk yields and reproductive performance. However, the beneficial effects on rumen modulation and animal performance have not been consistently observed. This review discusses the effects of tannins on nitrogen metabolism in the rumen and intestine, and microbial populations (bacteria, protozoa, fungi and archaea), metabolism of tannins, microbial tolerance mechanisms to tannins, inhibition of methanogenesis, ruminal biohydrogenation processes and performance of animals. The discrepancies of responses of tannins among different studies are attributed to the different chemical structures (degree of polymerisation, procyanidins to propdelphinidins, stereochemistry and C-C bonding) and concentrations of tannins, and type of diets. An establishment of structure-activity relationship would be required to explain differences among studies and obtain consistent beneficial tannin effects. PMID:20815041

    Irritable bowel syndrome (IBS) is a functional gastrointestinal disease with a high population prevalence. The disorder can be debilitating in some patients, whereas others may have mild or moderate symptoms. The most important single risk factors are female sex, younger age and preceding gastrointestinal infections. Clinical symptoms of IBS include abdominal pain or discomfort, stool irregularities and bloating, as well as other somatic, visceral and psychiatric comorbidities. Currently, the diagnosis of IBS is based on symptoms and the exclusion of other organic diseases, and therapy includes drug treatment of the predominant symptoms, nutrition and psychotherapy. Although the underlying pathogenesis is far from understood, aetiological factors include increased epithelial hyperpermeability, dysbiosis, inflammation, visceral hypersensitivity, epigenetics and genetics, and altered brain-gut interactions. IBS considerably affects quality of life and imposes a profound burden on patients, physicians and the health-care system. The past decade has seen remarkable progress in our understanding of functional bowel disorders such as IBS that will be summarized in this Primer. PMID:27159638

    Full Text Available Natalya Iorio, Zubair Malik, Ron Schey Section of Gastroenterology, Department of Medicine, Temple University Hospital, Philadelphia, PA, USA Abstract: Irritable bowel syndrome (IBS is a chronic functional gastrointestinal disorder characterized by recurrent abdominal pain and abnormal bowel patterns. Alteration in gut flora, visceral hypersensitivity, and abnormal bowel motility are among numerous factors in the complex pathophysiology of IBS. Antibiotics have been used adjunctively to treat IBS for many years but are associated with various systemic side effects. Rifaximin is a nonabsorbable, broad-spectrum antimicrobial that inhibits bacterial RNA synthesis by binding the β-subunit of microbial RNA polymerase. It targets the gastrointestinal tract and works by reducing the quantity of gas-producing bacteria and altering the predominant species of bacteria present. In vivo animal studies suggest additional beneficial mechanisms of rifaximin, including reducing mucosal inflammation and visceral hypersensitivity. Clinical studies have demonstrated that rifaximin improves symptoms associated with IBS, such as bloating, flatulence, stool consistency, and abdominal pain, and has a side-effect profile similar to placebo. Although additional investigation into optimal dosing, treatment duration, and potential resistance is required, rifaximin presents as a safe and beneficial addition to the current management options for IBS.

    2014-12-01

    Full Text Available A wide range of dyspeptic symptoms in clinical practice reflect the high prevalence of functional disorders of the gastrointestinal (GI tract. Prokinetic agents are the current mainstay in the therapy of functional dyspepsia. One of these drugs is itopride. We evaluated therapeutic efficacy of itopride according to the literature review. The therapeutic potential of itopride is connected with a dual effect: influencing of enzyme acetylcholinesterase activity and blocking dopamine D2 receptors. After the itopride administration, the contractility of smooth muscle in the upper GI tract increases. Itopride is a drug with rapid absorption from the small bowel; its peak serum concentration occurs 35 minutes after oral administration. Itopride does not pass the blood-brain barrier and does not affect the heart rate by influencing the QT segment. Itopride is a safe prokinetic agent with positive influence on the symptoms of functional dyspepsia such as postprandial fullness, bloating, and gastric emptying. Itopride could also be used for the therapy of the mild form of gastro-oesophageal reflux.

    Oral contraceptives are used since more than 50 years and are very popular due to offering more than 99% confidence in preventing pregnancy. Over 100 million women worldwide use oral contraceptives. In the UK 27% of women between 16 and 49 y. use pills. In the United States they are about 30%, in Germany - 40%, and in The Netherlands - 60%. According to a study by B. Pehlivanov, 2008, in Bulgaria only 4% of women use OC. (1) Despite the convenience and security, in the U.S.A. 29% of women taking OC interrupt prematurely their use (2), while the percentage of adolescents appears to be higher (3) Earlier studies of the reasons for refusal of OC focus on their influence on the menstrual cycle, as well as on some physical side effects such as the appearance of hair growth, weight gain, bloating etc. They paid very little attention to their impact on mood and sexual behavior of women (4). Newer studies suggest that the side effects associated with mood and sexual behavior proved more powerful factor leading to early termination of the use of OC (5). This paper is a review of the literature and evaluation of the facts presented in studies from different countries. They found a high incidence of symptoms such as anxiety, susceptibility to stress, mood changes, incl. depression, anxiety, increased irritability and affection of sexual desire of women. (6) There are many indications that OC-users are at increased risk of suicide and mental illnesses. (9). PMID:26411194

    We present the case of a patient in whom consecutive imaging assessment and surgery demonstrated the obvious progression of colorectal endometriosis under continuous medical therapy. A 26-year-old nullipara presented with secondary dysmenorrhea, deep dyspareunia, diarrhea, and constipation during menstruation. Magnetic resonance imaging (MRI) assessment revealed 2 right ovarian endometriomas, but no deep endometriosis lesion. Intraoperatively, we found a 2-cm length of thickened and congestive area of sigmoid colon, along with small superficial lesions arising in the small bowel and appendix. We performed ablation of ovarian endometriomas and appendectomy, and decided to not resect the bowel. Postoperative computed tomography-based virtual colonoscopy (CTC) revealed a slight abnormality of the sigmoid colon. Endorectal ultrasound identified a normal rectum and sigmoid colon. Despite long-term continuous medical treatment, the patient presented 4 years later with impaired digestion consisting in constipation alternating with diarrhea, bloating, dyschesia, and pelvic pain. MRI and CTC revealed an abnormal sigmoid colon from 42 to 50 cm above the anus, with digestive tract diameter reduced from 10 mm down to the virtual lumen, along with an overall rigid appearance. Laparoscopy revealed the extent of endometriosis lesions in the sigmoid colon and multiple implantations in the small bowel. We performed sigmoid and small bowel resection. This case demonstrates the obvious progression of deep rectal endometriosis despite 4 years of continuous hormonal therapy. PMID:27130533

    Irritable bowel syndrome (IBS) is a condition characterized by abdominal pain, bloating, flatus, and altered bowel habits. The role of dietary components in inducing IBS symptoms is difficult to explore. To date, foods are not considered a cause but rather symptom-triggering factors. Particular interest has been given to the so-called FODMAPs (fermentable oligo-, di-, and monosaccharides and polyols). We aimed to summarize the evidence from the most common approaches to manage suspected food intolerance in IBS, with a particular interest in the role of FODMAPs and the effects of a low FODMAP diet. We reviewed literature, consulting PubMed and Medline by using the search terms FODMAP(s), fructose, lactose, fructans, galactans, polyols (sorbitol, mannitol, maltitol, xylitol, erythritol, polydextrose, and isomalt), irritable bowel syndrome, and functional gastrointestinal symptoms. FODMAP-restricted diets have been used for a long time to manage patients with IBS. The innovation in the so-called FODMAP concept is that a global restriction should have a more consistent effect than a limited one in preventing abdominal distension. Even though all the potential low FODMAP diets provide good relief of symptoms in many patients, there is just a little relief in others. Several studies highlight the role of low FODMAP diets to improve symptoms in patients with IBS. The evidence on this dietary approach supports the hypothesis that a low FODMAP diet should be the first dietary approach. However, many points remain to be clarified, including the evaluation of possibly significant nutrition concerns. PMID:25694210

    The high-mass star-forming site G009.62-00.20E hosts the 6.7 GHz methanol maser source with the greatest flux density in the Galaxy which has been flaring periodically over the last ten years. We performed high-resolution astrometric measurements of the CH3OH, H2O, and OH maser emission and 7 mm continuum in the region. The radio continuum emission was resolved in two sources separated by 1300 AU. The CH3OH maser cloudlets are distributed along two north-south ridges of emission to the east and west of the strongest radio continuum component. This component likely pinpoints a massive young stellar object which heats up its dusty envelope, providing a constant IR pumping for the Class II CH3OH maser transitions. We suggest that the periodic maser activity may be accounted for by an independent, pulsating, IR radiation field provided by a bloated protostar in the vicinity of the brightest masers. We also report about the discovery of an elliptical distribution of CH3OH maser emission in the region of periodic v...

  12. Estimation of Hydrogen Production Rates from Radiolysable Material in Contact with Various Irradiated Fuels

    International Nuclear Information System (INIS)

    The storage of irradiated fuel is increasing as many installations are approaching their end of- ife and fuel or fuel-containing remnants from waste or samples are being placed in storage. Often these smaller experimental samples are mounted in epoxide resins or are placed containers with bitumen. It is particularly in combination with these radiolysable materials where the irradiation generates hydrogen that problems arise in longer term storage. The hydrogen generation results in either pressure buildup (with container bloating and eventual failure) or in case of gas release and mixture with air, a detonation. Previous work has examined the Phebus FPT1 bundle encased in resin where it was necessary for both transport and intermediate storage at Cadarache to assess this risk. This work is a first estimation of the radiolysis rates to be expected from various fuels and to assess the range of H2 production from radiolysable material based on the results of the FPT1 Phebus bundle. The first step is to make a correlation of the total activity with the burnup of UO2 fuel. Then using the H2 production rates measured for the Phebus fuel, an estimate of its dependence on fuel burn-up will be made and so help define the necessary design for the foreseen storage time.

    Supermassive stars (SMSs) forming via very rapid mass accretion (Mdot >~ 0.1 Msun/yr) could be precursors of supermassive black holes observed beyond redshift of about 6. Extending our previous work, we here study the evolution of primordial stars growing under such rapid mass accretion until the stellar mass reaches 10^{4 - 5} Msun. Our stellar evolution calculations show that a star becomes supermassive while passing through the "supergiant protostar'' stage, whereby the star has a very bloated envelope and a contracting inner core. The stellar radius increases monotonically with the stellar mass, until =~ 100 AU for M_* >~ 10^4 Msun, after which the star begins to slowly contract. Because of the large radius the effective temperature is always less than 10^4 K during rapid accretion. The accreting material is thus almost completely transparent to the stellar radiation. Only for M_* >~ 10^5 Msun can stellar UV feedback operate and disturb the mass accretion flow. We also examine the pulsation stability of a...

    Full Text Available There is no consensus as to what extent of "wrap" is required in a fundoplication for correction of gastroesophageal reflux disease (GERD.To evaluate if a complete (360 degree or partial fundoplication gives better control of GERD.A systematic search of MEDLINE and Scopus identified interventional and observational studies of fundoplication in children. Screening identified those comparing techniques. The primary outcome was recurrence of GERD following surgery. Dysphagia and complications were secondary outcomes of interest. Meta-analysis was performed when appropriate. Study quality was assessed using the Cochrane Risk of Bias Tool.2289 abstracts were screened, yielding 2 randomized controlled trials (RCTs and 12 retrospective cohort studies. The RCTs were pooled. There was no difference in surgical success between partial and complete fundoplication, OR 1.33 [0.67,2.66]. In the 12 cohort studies, 3 (25% used an objective assessment of the surgery, one of which showed improved outcomes with complete fundoplication. Twenty-five different complications were reported; common were dysphagia and gas-bloat syndrome. Overall study quality was poor.The comparison of partial fundoplication with complete fundoplication warrants further study. The evidence does not demonstrate superiority of one technique. The lack of high quality RCTs and the methodological heterogeneity of observational studies limits a powerful meta-analysis.

    Coeliac disease (CD) is an immune-mediated systemic disorder caused by ingestion of gluten found in wheat, rye and barley. It affects around 1% of children, but 90% of cases are considered to remain undiagnosed. CD classically presents with gastrointestinal manifestations including diarrhoea, bloating, weight loss and abdominal pain, but extra-intestinal features (including oral and dental manifestations) are increasingly being reported. Dental and oral manifestations such as dental enamel defects, delayed eruption of teeth, recurrent aphthous ulcers are well-recognised manifestations of CD. In patients with yet undiagnosed CD, these can sometimes be the only presenting features. Dentists have regular contact with well children, and therefore the visit to the dentist is an opportunity to suspect CD. When CD is suspected, Dental practitioners can liaise with the general medical practitioner to organise screening for coeliac disease. Positive serology will prompt onward referral to a paediatric gastroenterologist to confirm the diagnosis. The recent European Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) guidelines revised in 2012 have streamlined the diagnostic pathway for faster diagnosis of CD. Management involves strict adherence to a gluten free diet, which should lead to resolution of symptoms, recovery of intestinal mucosa and prevention of long-term complications associated with it. This article aims to describe CD, inform of recent changes to the diagnostic pathway and highlight the dental manifestations of the condition to equip dental practitioners to aid early diagnosis and initiation of treatment for children with CD.

    The rhizomes of Zingiber officinale Roscoe (Zingiberaceae), commonly known as ginger is an important kitchen spice and also possess a myriad health benefits. The rhizomes have been used since antiquity in the various traditional systems of medicine to treat arthritis, rheumatism, sprains, muscular aches, pains, sore throats, cramps, hypertension, dementia, fever, infectious diseases, catarrh, nervous diseases, gingivitis, toothache, asthma, stroke and diabetes. Ginger is also used as home remedy and is of immense value in treating various gastric ailments like constipation, dyspepsia, belching, bloating, gastritis, epigastric discomfort, gastric ulcerations, indigestion, nausea and vomiting and scientific studies have validated the ethnomedicinal uses. Ginger is also shown to be effective in preventing gastric ulcers induced by nonsteroidal anti-inflammatory drugs [NSAIDs like indomethacin, aspirin], reserpine, ethanol, stress (hypothermic and swimming), acetic acid and Helicobacter pylori-induced gastric ulcerations in laboratory animals. Various preclinical and clinical studies have also shown ginger to possess anti-emetic effects against different emetogenic stimuli. However, conflicting reports especially in the prevention of chemotherapy-induced nausea and vomiting and motion sickness prevent us from drawing any firm conclusion on its effectiveness as a broad spectrum anti-emetic. Ginger has been shown to possess free radical scavenging, antioxidant; inhibition of lipid peroxidation and that these properties might have contributed to the observed gastroprotective effects. This review summarizes the various gastroprotective effects of ginger and also emphasizes on aspects that warranty future research to establish its activity and utility as a gastroprotective agent in humans.

    2014-12-01

    The diagnosis of small intestinal bacterial overgrowth (SIBO) has increased considerably owing to a growing recognition of its association with common bowel symptoms including chronic diarrhea, bloating, abdominal distention, and the irritable bowel syndrome. Ideally, an accurate and objective diagnosis of SIBO should be established before initiating antibiotic treatment. Unfortunately, no perfect test exists for the diagnosis of SIBO. The current gold standard, small-bowel aspiration and quantitative culture, is limited by its high cost, invasive nature, lack of standardization, sampling error, and need for dedicated infrastructure. Although not without shortcomings, hydrogen breath testing provides the simplest noninvasive and widely available diagnostic modality for suspected SIBO. Carbohydrates such as lactulose and glucose are the most widely used substrates in hydrogen breath testing, with glucose arguably providing greater testing accuracy. Lactose, fructose, and sorbitol should not be used as substrates in the assessment of suspected SIBO. The measurement of methane in addition to hydrogen can increase the sensitivity of breath testing for SIBO. Diagnostic accuracy of hydrogen breath testing in SIBO can be maximized by careful patient selection for testing, proper test preparation, and standardization of test performance as well as test interpretation.

    2016-02-01

    Small intestinal bacterial overgrowth (SIBO) is characterized by an excessive amount of bacteria in the small intestine and a constellation of symptoms that include bloating, pain, gas, and diarrhea. Although known for many decades, there is a lack of consensus and clarity regarding the natural history and methods for its diagnosis. Several tests have been proposed, including the glucose breath test, lactulose breath test, small intestinal aspiration and culture, and others. However, there is a lack of standardization of these tests and their interpretation. Treatment of SIBO remains empirical; generally, broad spectrum antibiotics are recommended for 2 weeks (amoxicillin, rifaximin, ciprofloxacin, etc.) but evidence for their use is fair. Clearly, there is a strong need to develop a systematic approach for the management of SIBO and to perform multicenter clinical trials for the treatment of SIBO. In this review, we will discuss the current evidence for the diagnosis and treatment of SIBO, which includes (1) elimination/modification of the underlying causes, (2) induction of remission (antibiotics and elemental diet), and (3) maintenance of remission (promotility drugs, dietary modifications, repeat or cyclical antibiotics).

    Irritable bowel syndrome (IBS) is a common condition characterized by abdominal pain or discomfort, bloating, and altered stool form and passage. Small intestinal bacterial overgrowth (SIBO) is a condition in which there is overgrowth of bacteria in small bowel in excess of 10⁵ colony forming units per milliliter on culture of the upper gut aspirate. Frequency of SIBO varied from 4%-78% among patients with IBS and from 1%-40% among controls. Higher frequency in some studies might be due to fallacious criteria [post-lactulose breath-hydrogen rise 20 PPM above basal within 90 min (early-peak)]. Glucose hydrogen breath test (GHBT) has a low sensitivity to diagnose SIBO. Hence, studies based on GHBT might have under-estimated frequency of SIBO. Therefore, it is important to analyze these studies carefully to evaluate whether the reported association between IBS and SIBO is over or under-projected. This review evaluates studies on association between SIBO and IBS, discordance between different studies, their strength and weakness including methodological issues and evidence on therapeutic manipulation of gut flora on symptoms of IBS.

    We report the discovery of the two hot-Jupiters EPIC210957318b and EPIC212110888b (hereafter EPIC-318b and EPIC-888b, respectively). The two planets were detected transiting their main-sequence star with periods $\\sim$ 4.099 and $\\sim$ 2.996 days, in campaigns 4 and 5 of the extension of the Kepler mission, K2. Subsequent ground-based radial velocity follow-up with SOPHIE, HARPS-N and CAFE, established the planetary nature of the transiting objects. We analyzed the transit signal, radial velocity and spectral energy distributions of the two systems to characterize their properties. Both planets (EPIC-318b and EPIC-888b) are bloated hot-Jupiters (1.25 $R_{\\rm Jup}$ and 1.33 $R_{\\rm Jup}$) around relatively bright (V =13.5 and V=11.5), slow rotating main-sequence (G8 and F9) stars. Thus, these systems are good candidates for detecting the Rossiter-MacLaughlin effect to measure their obliquity and for atmospheric studies.

    There is no consensus as to what symptoms or quality-of-life (QOL) domains should be measured as patient-reported outcomes (PROs) in ovarian cancer clinical trials. A panel of experts convened by the National Cancer Institute reviewed studies published between January 2000 and August 2011. The results were included in and combined with an expert consensus-building process to identify the most salient PROs for ovarian cancer clinical trials. We identified a set of PROs specific to ovarian cancer: abdominal pain, bloating, cramping, fear of recurrence/disease progression, indigestion, sexual dysfunction, vomiting, weight gain, and weight loss. Additional PROs identified in parallel with a group charged with identifying the most important PROs across cancer types were anorexia, cognitive problems, constipation, diarrhea, dyspnea, fatigue, nausea, neuropathy, pain, and insomnia. Physical and emotional domains were considered to be the most salient domains of QOL. Findings of the review and consensus process provide good support for use of these ovarian cancer-specific PROs in ovarian cancer clinical trials. PMID:25006190

    Full Text Available Peptic ulcers are produced by an imbalance between gastro-duodenal mucosal defense mechanisms and damaging forces of gastric acid and pepsin, combined with superimposed injury from environmental or immunologic agents. Most common symptoms of peptic ulcer disease are abdominal discomfort, gnawing ache, occurs 2 to 3 hours after meal, other symptoms includes weight loss, poor appetite, bloating, nausea, vomiting etc. Some time duodenal wall perforates; bleeding due to the ulcer breaks blood vessels and obstructs the path of food trying to leave the stomach. Various studies have shown the association of Helicobacter pylori with peptic ulcers. Probiotic lactic acid bacteria are proposed to cure peptic ulcers by reducing colonization of H. pylori with stomach wall and by eradicating already established infection. A bacteriocin producing probiotic strain of P. acidilactici BA28 was evaluated for its antimicrobial activity against a number of Gram-positive and Gram-negative pathogens. Bacteriocin BA28 was partially purificated and characterized following in vitro assays. Preliminary investigations against H. plyori have suggested its effectiveness against peptic ulcer disease and therefore could be exploited to develop novel therapeutics.

    In this paper, we use genetic programming (GP) to synthesize composite operators and composite features from combinations of primitive operations and primitive features for object detection. The motivation for using GP is to overcome the human experts' limitations of focusing only on conventional combinations of primitive image processing operations in the feature synthesis. GP attempts many unconventional combinations that in some cases yield exceptionally good results. To improve the efficiency of GP and prevent its well-known code bloat problem without imposing severe restriction on the GP search, we design a new fitness function based on minimum description length principle to incorporate both the pixel labeling error and the size of a composite operator into the fitness evaluation process. To further improve the efficiency of GP, smart crossover, smart mutation and a public library ideas are incorporated to identify and keep the effective components of composite operators. Our experiments, which are performed on selected training regions of a training image to reduce the training time, show that compared to normal GP, our GP algorithm finds effective composite operators more quickly and the learned composite operators can be applied to the whole training image and other similar testing images. Also, compared to a traditional region-of-interest extraction algorithm, the composite operators learned by GP are more effective and efficient for object detection. PMID:15971921

    2013-06-01

    Full Text Available Following an application from Clasado Limited, submitted for authorisation of a health claim pursuant to Article 13(5 of Regulation (EC No 1924/2006 via the Competent Authority of Malta, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA was asked to deliver an opinion on the scientific substantiation of a health claim related to Bimuno® GOS and reducing gastro-intestinal discomfort. The food constituent, Bimuno® GOS, a mixture of β-galacto-oligosaccharides, which is the subject of the health claim, is sufficiently characterised. The claimed effect proposed by the applicant is “reduce bloating, flatulence and abdominal pain. These effects can be described collectively as abdominal discomfort” and the target population proposed by the applicant is the general adult population. Reducing gastro-intestinal discomfort is a beneficial physiological effect. A health claim on Bimuno® GOS and reducing gastro-intestinal discomfort has already been assessed by the Panel with an unfavourable outcome. The supplementary information submitted by the applicant in this application did not provide evidence that could be used for the scientific substantiation of this claim.

    Full Text Available Background. Loss of normal bowel function caused by nerve injury, neurological disease or congenital defects of the nervous system is termed neurogenic bowel dysfunction (NBD. It usually includes combinations of fecal incontinence, constipation, abdominal pain and bloating. When standard treatment of NBD fails surgical procedures are often needed. Neurostimulation has also been investigated, but no consensus exists about efficacy or clinical use. Methods. A systematic literature search of NBD treated by sacral anterior root stimulation (SARS, sacral nerve stimulation (SNS, peripheral nerve stimulation, magnetic stimulation, and nerve re-routing was made in Pubmed, Embase, Scopus, and the Cochrane Library. Results. SARS improves bowel function in some patients with complete spinal cord injury (SCI. Nerve re-routing is claimed to facilitate defecation through mechanical stimulation of dermatomes in patients with complete or incomplete SCI or myelomeningocele. SNS can reduce NBD in selected patients with a variety of incomplete neurological lesions. Peripheral stimulation using electrical stimulation or magnetic stimulation may represent non-invasive alternatives. Conclusion. Numerous methods of neurostimulation to treat NBD have been investigated in pilot studies or retrospective studies. Therefore, larger controlled trials with well-defined inclusion criteria and endpoints are recommended before widespread clinical use of neurostimulation against NBD.

  7. Dismantling the dinosaurs: A look at U.S. M and A trends

    International Nuclear Information System (INIS)

    Current trends in the oil and gas merger and acquisition (M and A) marketplace suggest that business as usual isn't usual anymore. Are these trends the harbinger of bad tidings? Will the industry collapse continue to take on dimensions of a full scale implosion, or are we sitting on the brink of the next boom? What we know at this point is that the dinosaurs-the short-sighted, the bloated, the arrogant, the unchanging-are going extinct. Companies are disappearing. Survivors are turning lean and flexible. The industry isn't just changing; it's evolving a new breed, with M and A activity a bridge between the old and the new. The current state of the industry is shocking. We all know that drilling activity is at its lowest level in 4 decades. That is why acquisitions are the only game in town and why the acquisition business is booming. If drilling activity is down about 25%, that is small beans compared with acquisitions, which are down 50-70%

  8. Diagnosis and Management of Adnexal Masses.

    2016-04-15

    Adnexal masses can have gynecologic or nongynecologic etiologies, ranging from normal luteal cysts to ovarian cancer to bowel abscesses. Women who report abdominal or pelvic pain, increased abdominal size or bloating, difficulty eating, or rapid satiety that occurs more than 12 times per month in less than a year should be evaluated for ovarian cancer. Pelvic examination has low sensitivity for detecting an adnexal mass; negative pelvic examination findings in a symptomatic woman should not deter further workup. Ectopic pregnancy must be ruled out in women of reproductive age. A cancer antigen 125 (CA 125) test may assist in the evaluation of an adnexal mass in appropriate patients. CA 125 levels are elevated in conditions other than ovarian cancer. Because substantial overlap in CA 125 levels between pre- and postmenopausal women may occur, this level alone is not recommended for differentiating between a benign and a malignant adnexal mass. Transvaginal ultrasonography is the first choice for imaging of an adnexal mass. Large mass size, complexity, projections, septation, irregularity, or bilaterality may indicate cancer. If disease is suspected outside of the ovary, computed tomography may be indicated; magnetic resonance imaging may better show malignant characteristics in the ovary. Serial ultrasonography and periodic measurement of CA 125 levels may help in differentiating between benign or potentially malignant adnexal masses. If an adnexal mass larger than 6 cm is found on ultrasonography, or if findings persist longer than 12 weeks, referral to a gynecologist or gynecologic oncologist is indicated. PMID:27175840

  9. Chili Peppers, Curcumins, and Prebiotics in Gastrointestinal Health and Disease.

    2016-04-01

    There is growing evidence for the role of several natural products as either useful agents or adjuncts in the management of functional GI disorders (FGIDs). In this review, we examine the medical evidence for three such compounds: chili, a culinary spice; curcumin, another spice and active derivative of a root bark; and prebiotics, which are nondigestible food products. Chili may affect the pathogenesis of abdominal pain especially in functional dyspepsia and cause other symptoms. It may have a therapeutic role in FGIDs through desensitization of transient receptor potential vanilloid-1 receptor. Curcumin, the active ingredient of turmeric rhizome, has been shown in several preclinical studies and uncontrolled clinical trials as having effects on gut inflammation, gut permeability and the brain-gut axis, especially in FGIDs. Prebiotics, the non-digestible food ingredients in dietary fiber, may serve as nutrients and selectively stimulate the growth and/or activity of certain colonic bacteria. The net effect of this change on colonic microbiota may lead to the production of acidic metabolites and other compounds that help to reduce the production of toxins and suppress the growth of harmful or disease-causing enteric pathogens. Although some clinical benefit in IBS has been shown, high dose intake of prebiotics may cause more bloating from bacterial fermentation. PMID:26973345

    Full Text Available The purpose of this article is to research and retrieve patent information regarding the therapeutic use of truffles. Truffles have a unique value as a foodstuff and impact positively on human health and well-being. They are applied in such industries as the pharmaceutical industry and the cosmetic industry. Patent documentation available in the Espacenet network and the Patentscope service were analyzed by key word and patent specifications were examined to describe state of the art and to identify scientific research trends in therapeutic applications of truffles. Medicinal properties of truffles such as the anticancer or cardiovascular effect, a reduction in blood lipids, immunological resistance and increased energy were identified. Other therapeutic benefits include sedative action, prevention of hormonal imbalances in women, pre-menopause symptom relief, senile urethritis and prostate disorders, sleep disorders and increased absorption of calcium from milk. Truffles can also be used to alleviate symptoms of milk intolerance such as diarrhoea or bloating, to ease rheumatic pains and to treat and prevent further development or recurrence of senile cataract.

  11. Ovarian Cancer Stroma: Pathophysiology and the Roles in Cancer Development

    International Nuclear Information System (INIS)

    Ovarian cancer represents one of the cancers with the worst prognostic in adult women. More than half of the patients who present with clinical signs such as abdominal bloating and a feeling of fullness already show advanced stages. The majority of ovarian cancers grow as cystic masses, and cancer cells easily spread into the pelvic cavity once the cysts rupture or leak. When the ovarian cancer cells disseminate into the peritoneal cavity, metastatic nests may grow in the cul-de-sac, and in more advanced stages, the peritoneal surfaces of the upper abdomen become the next largest soil for cancer progression. Ascites is also produced frequently in ovarian cancers, which facilitates distant metastasis. Clinicopathologic, epidemiologic and molecular studies on ovarian cancers have improved our understanding and therapeutic approaches, but still further efforts are required to reduce the risks in the patients who are predisposed to this lethal disease and the mortality of the patients in advanced stages. Among various molecules involved in ovarian carcinogenesis, special genes such as TP53, BRCA1 and BRCA2 have been well investigated. These genes are widely accepted as the predisposing factors that trigger malignant transformation of the epithelial cells of the ovary. In addition, adnexal inflammatory conditions such as chronic salpingitis and ovarian endometriosis have been great research interests in the context of carcinogenic background of ovarian cancers. In this review, I discuss the roles of stromal cells and inflammatory factors in the carcinogenesis and progression of ovarian cancers

    Full Text Available Swollen Hindgut syndrome (SHG of black tiger shrimp Penaeus monodon Fabricius, 1798post larvae has been reported from Bangladesh shrimp hatcheries in recent years. At present SHG is abudding problem causing significant economic loss to the shrimp hatcheries in Bangladesh. Unlike therapid mortalities associated with viral disease such as white spot syndrome and yellow head virus,progression of SHG is gradual leading to low level mortalities without affecting swimming activity. Thesign of SHG are a bloated or swollen in hind gut area, with the posterior digestive tract convolutingthrough the last abdominal segment. This syndrome tends to occur at later PL stages, typically afterPL10. Two types of Vibrio spp. were isolated from the swollen hindgut syndrome post larvae, identified asVibrio harveyi (Johnson and Shunk 1936and Vibrio alginolyticus (Miyamoto, Nakamura & Takizawa1961. Among these V. alginolyticus was dominant to V. harveyi. The bacterial isolates showed sensitiveto oxytetracycline (OTC, norfloxacin and ciprofloxacin and resistant to penicillin, ampicillin andamoxycillin. The luminous V. harveyi showed resistant to many antibiotics and susceptibility to only twodrugs. The cause of swollen hindgut syndrome (SHG was probably bacterial infections and poor waterquality, possibly heavy metal i.e. iron, the presence of toxic substances from chemical prophylactics andlow quality or diseased nauplii.

    Probiotic supplementation has traditionally focused on gut health. However, in recent years, the clinical applications of probiotics have broadened to allergic, metabolic, inflammatory, gastrointestinal and respiratory conditions. Gastrointestinal health is important for regulating adaptation to exercise and physical activity. Symptoms such as nausea, bloating, cramping, pain, diarrhoea and bleeding occur in some athletes, particularly during prolonged exhaustive events. Several studies conducted since 2006 examining probiotic supplementation in athletes or highly active individuals indicate modest clinical benefits in terms of reduced frequency, severity and/or duration of respiratory and gastrointestinal illness. The likely mechanisms of action for probiotics include direct interaction with the gut microbiota, interaction with the mucosal immune system and immune signalling to a variety of organs and systems. Practical issues to consider include medical and dietary screening of athletes, sourcing of recommended probiotics and formulations, dose-response requirements for different probiotic strains, storage, handling and transport of supplements and timing of supplementation in relation to travel and competition.

    2015-08-01

    Full Text Available Gastroparesis is a common gastrointestinal complication in diabetes, induced by hyperglycemia and characterized by delayed gastric emptying and upper abdominal symptoms, such asnausea, vomiting, early satiety, bloating and epigastric pain. Diabetic gastroparesis (DGP affects life quality and glycemic control, and is a challenge to treat in both Western and Eastern medicine. Routine treatment in Western medicine includes gastric emptying promoted by prokinetic agents, gastric pacemaking, or surgery combined with lifetime hormono-therapy, all of which have unavoidable side effects and limitations, and are very expensive. Complementary and alternative medical treatments like acupuncture, moxibustion, and massage are becoming more and more attractive because of their effectiveness, fewer side effects, and reliable safety. This article aims to introduce representative methods of complementary and alternative medicine to treat DGP, which were searched in English through Pubmed and in Chinese through CNKI (China Knowledge Resource Integrated Database. Several lines of evidence demonstrated the effects of single or combined complementary alternative therapies on DGP outcomes; however, the mechanisms were rarely investigated. Randomized controlled trials are undoubtedly required in future studies.

    Full Text Available Introduction: According to previous studies celiac disease(CD is frequently associated with chronic gastritis. The aim of this study was to assess the prevalence of CD and Helicobacter pylori in patients with dyspepsia. Methods: 325 patients were studied from April 2008 to April 2009 who underwent endoscopic procedures for dyspepsia. Gastric antrum, duodenal biopsies, serology with tissue Transglutaminase Antibodies(tTGA and total IgA were performed for detection of H. pylori and CD. Results: Out of 325 patients 312(96% had a positive H. pylori. Heart burn and bloating were the most prevalent symptoms in this study. Twenty one of 25 patients with positive histology for CD who had gastric biopsies were positive for H. pylori(84%. Duodenal biopsy specimens results have shown normal histology in 213(65.5%, hyperplastic polyps in 1(0.4%, duodenitis in 79(24.3% and abnormality in small bowel (Marsh I-IIIc in 25(10%. In term of the serological analysis, 9 of 26 tTGA positive patients had abnormal histology (Marsh I-IIIc(2.7%. Conclusion: Similar to previous reports, we found a high prevalence of H. pylori infection and celiac disease in dyspeptic patients. Therefore, further studies for screening occult CD in dyspeptic patients is seems necessary.

    2010-01-01

    Full Text Available The use of plant extracts with the objective of improving production results and the quality of food articles of animal origin is an area which is acquiring increasing scientific importance. Numerous investigations carried out so far on ruminants and other species of domestic animals have been aimed at examining specific bioactive matter of plants. The results of these investigations have demonstrated a positive influence on the production results. A large number of data indicate that plant extracts added to animal feed contribute to increasing overall productivity. Furthermore, plant extracts as additives in animal feed have a positive effect also on the health condition of the animals. A large number of plants have characteristics which potentially improve consumption, digestibility and conversion of food, and also growth. Examinations have been performed of the effects of different plant extracts on food consumption, wool growth, growth and composition of the trunk, milk production, reproductive parameters, agents for wool shearing, preventing bloat, methane production, as well as the influence of plants on curbing nematode infestations of ruminants. This work presents a review of scientific investigations of different plant species and their effects on the production characteristics of ruminants. .

    Full Text Available Abstract Background To identify early symptoms of familial adenomatous polyposis with a view to improve early diagnosis and treatment. Diagnosis on the basis of genetic testing is usually limited to where there is a known family history, so FAP is more usually diagnosed on clinical grounds. Except for those identified via FAP registers, the majority of patients are symptomatic at the time of diagnosis. Methods We undertook a retrospective study of 143 FAP patients treated at the Department of Surgery, University of Erlangen between 1971 and 2000. We identified patterns of symptoms, endoscopic findings and extracolonic manifestations in three age groups. Results FAP was diagnosed clinically on the basis of symptoms in 84% (120/143 of these patients. Most presented with intestinal symptoms such as colonic bleeding (68% and diarrhea (42%. All but one of the patients between 20 and 40 years old had rectal polyps (98.7%, 75/76, whereas in those over 40 years old the prevalence was 76% (35/46. Non-specific symptoms such as abdominal pain, fatigue and bloating were less frequent and were mainly reported by patients older than 40. Conclusion The commonest presenting features of FAP are alteration of bowel habit and rectal bleeding, but both are found in many other conditions. Patients with these findings need immediate endoscopy to allow prompt diagnosis and prophylactic surgery.

    Irritable bowel syndrome (IBS) is a common chronic disorder with a prevalence ranging from 5 to 10 percent of the world's population. This condition is characterised by abdominal discomfort or pain, altered bowel habits, and often bloating and abdominal distension. IBS reduces quality of life in the same degree of impairment as major chronic diseases such as congestive heart failure and diabetes and the economic burden on the health care system and society is high. Abnormalities have been reported in the neuroendocrine peptides/amines of the stomach, small- and large intestine in patients with IBS. These abnormalities would cause disturbances in digestion, gastrointestinal motility and visceral hypersensitivity, which have been reported in patients with IBS. These abnormalities seem to contribute to the symptom development and appear to play a central role in the pathogenesis of IBS. Neuroendocrine peptides/amines are potential tools in the treatment and diagnosis of IBS. In particular, the cell density of duodenal chromogranin A expressing cells appears to be a good histopathological marker for the diagnosis of IBS with high sensitivity and specificity.

    A large number of clinical studies using breath testing and a smaller number of studies using quantitative cultures of the upper small intestine established a link between irritable bowel syndrome (IBS) and small intestinal bacterial overgrowth (SIBO). A series of 12 studies both prospective and retrospective in design in a population of patients with SIBO without IBS showed that the non-absorbable antibiotic rifaximin can eradicate SIBO as proved through decrease of the exhaled hydrogen and methane in breath tests. The efficacy of rifaximin was superior over the comparator treatment in most of these studies. Based on these findings, short course rifaximin was tested in various concentrations in eight open-label trials in patients with IBS and proven SIBO by breath test. Similar efficacy of rifaximin was shown in SIBO eradication; this was accompanied by improvement of the global score for IBS symptoms. Finally, five double-blind randomized clinical trials were conducted in patients with IBS; four were placebo-controlled. The larger trials were TARGET 1 and TARGET 2 studies testing rifaximin at a regimen of 550 mg tid for 14 days. All trials showed a significant superiority of rifaximin over comparator for the improvement of global symptoms of IBS and bloating. Although the aforementioned results render rifaximin a revolutionary therapeutic approach for IBS, several concerns on induction of antimicrobial resistant flora remain. PMID:26202193

    2015-11-01

    Full Text Available Small intestinal bacterial overgrowth (SIBO is a condition of increased microbial load in the small intestine. The microbes feed on dietary carbohydrates and starches via fermentation, leading to gas production, inflammation and damage to the lining of the small intestine. Clinical presentation is varied, including abdominal pain, bloating, malabsorption and systemic symptoms. SIBO is associated with many challenging and chronic conditions such as fibromyalgia, chronic fatigue and chronic pain syndromes, and has been shown to be a causative factor in two out of three cases of irritable bowel syndrome. Symptoms improve with antimicrobial treatment, but recurrence is common. Many providers may not be aware of SIBO. This narrative review highlights a clinical case and the most recent literature regarding SIBO, including history, clinical presentation, prevalence, pathophysiology, diagnostic workup, treatment and prevention. Integrative medicine approaches, including diet, supplements and manual therapies, are also reviewed. SIBO can be a challenging condition and requires an integrative, patient-centered approach. Further studies are needed to guide clinicians in the workup and treatment of SIBO.

    2015-09-01

    AST-120 (kremezin) exhibits its favourable effects in reducing the levels of renal toxins by selective adsorption of low molecular weight substances from the intestinal lumen. So far, a vast majority of studies were focused on the role of AST-120 in the treatment of chronic kidney diseases and cardiovascular disorders, and positive therapeutic effects of the agent have already been confirmed in clinical conditions. Up to the present, there are only a few studies regarding the role of AST-120 in irritable bowel syndrome (IBS). Compelling data suggest the ability of the compound to adsorb protein-bound uremic toxins and mast cell derived mediators and to modulate the farnesoid X receptor, which is a bile acid sensor indispensable for maintaining homeostasis in the intestine. In this review we focus on the actions of AST-120 on intestinal permeability, reduction of visceral sensitivity and alteration of gut motility. We also discuss whether AST-120 can mitigate common IBS symptoms, such as abdominal pain, bloating and malfunction of the colonic transit and thus improve the quality of life of patients with IBS.

    Rifaximin is a broad spectrum oral antibiotic with antimicrobial activity against Gram-positive and Gram-negative aerobic and anaerobic bacteria. It is poorly absorbed and thus has a highly favorable safety profile. Rifaximin has been shown to be effective in the treatment of traveler’s diarrhea, functional bloating and irritable bowel syndrome, small bowel bacterial overgrowth and in the prevention of recurrent overt hepatic encephalopathy. In addition, there is emerging evidence for a possible beneficial effect of rifaximin in the treatment of uncomplicated diverticular disease and in the prevention of recurrent diverticulitis. The use of rifaximin is associated with a low incidence of development, or persistence of spontaneous bacterial mutants. Moreover, the development of important drug resistance among extra-intestinal flora during rifaximin therapy is unlikely because of minimal systemic absorption and limited cross-resistance of rifaximin with other antimicrobials. This review addresses the current and emerging role of rifaximin in the treatment of gastrointestinal and liver disorders. PMID:27547007

    Two new members of "IBS Patient Association" met at a meeting. Feeling somewhat lost, not knowing anybody present, they introduced themselves to each other. After exchanging names, one asks the other - "What's your problem?" The other one answers - "I got constipation that laxatives fail to relieve, and my belly, which is always bloated, sometimes hurts so much that I can´t even leave home". Deeply surprised, the first individual inquires - "What are you doing here then?" "Why, I came to this meeting looking for some help for my irritable colon", she answered. "Irritable colon? That's no irritable colon. Irritable bowel syndrome is what I suffer from, and it's diarrhea that won't let me be; can't stop running to the toilet, and cramps just pop up any time". Now both looked surprised. Both thought they had come to the wrong meeting, and both were on the verge of leaving. Luckily, the Association's secretary showed up and explained that both had IBS.

  4. Heavy ion bombardment of silicates and nitrides

    International Nuclear Information System (INIS)

    Several silicates, including α-quartz, zirconium silicate, thorium silicate, LiAlSiO4, a silicate glass and several nitrides, α and β Si3N4, AlN, ZrN as well as Si2N2O and ThO2, have been irradiated by 1019 to 1021 Krypton (3 MeV) ions/m2. The damaged powders of original particle size less than 5 μm, have been examined by x-ray diffraction and electron microscope methods. The silicates and Si2N2O become non-crystalline by 10 x 1019 ions/m2. The particles change shape, extending and bloating under prolonged irradiations of the order of 100 x 1019 ions/m2. Silicate glass also undergoes this irradiation creep process. The nitrides and ThO2 behave quite differently and even at fluences of 200 x 1019 x ions/m-2 the powders remain crystalline, retaining relatively sharp edges to the particles without exhibiting irradiation creep. This difference in behavior can be related to the nature of the framework crystal structures, flexible for the silicates with variable bond angles, rigid for the nitrides with fixed bond angles. This may explain the behavior of radioactive minerals not found in a metamict condition. (author)

    We present coupled stellar evolution (SE) and 3D radiation-hydrodynamic (RHD) simulations of the evolution of primordial protostars, their immediate environment, and the dynamic accretion history under the influence of stellar ionizing and dissociating UV feedback. Our coupled SE-RHD calculations result in a wide diversity of final stellar masses covering $10~M_\\odot \\lesssim M_* \\lesssim 10^3~M_\\odot$. The formation of very massive ($\\gtrsim 250~M_\\odot$) stars is possible under weak UV feedback, whereas ordinary massive (a few $\\times 10~M_\\odot$) stars form when UV feedback can efficiently halt the accretion. Weak UV feedback occurs in cases of variable accretion, in particular when repeated short accretion bursts temporarily exceed $0.01~M_\\odot~{\\rm yr}^{-1}$, causing the protostar to inflate. In the bloated state, the protostar has low surface temperature and UV feedback is suppressed until the star eventually contracts, on a thermal adjustment timescale, to create an HII region. If the delay time betwe...

    Over the last decades, the incidence of infestation by minor parasites has decreased in developed countries. Infectious agents can also suppress autoimmune and allergic disorders. Some investigations show that various protozoa and helminthes are connected with the main immune-mediated intestinal conditions including celiac disease (CD), inflammatory bowel diseases (IBD) and irritable bowel syndrome (IBS). Celiac disease is a digestive and autoimmune disorder that can damage the small intestine and characterized by a multitude gastrointestinal (GI) and extra GI symptoms. IBD (including ulcerative colitis and Crohn's disease) is a group of inflammatory conditions of the small intestine and colon. The etiology of IBD is unknown, but it may be related to instability in the intestinal microflora that leading to an immoderate inflammatory response to commensal microbiota. Irritable bowel syndrome (IBS) is a common, long-term condition of the digestive system. Bloating, diarrhoea and/or constipation are nonspecific symptoms of IBS. Various studies have shown that some intestinal parasites can effect on immune system of infected hosts and in some cases, they are able to modify and change the host's immune responses, particularly in autoimmune disorders like celiac disease and IBD. The main objective of this review is to investigate the relationship between intestinal parasites and different inflammatory bowel disorders. PMID:25926937

    A variety of human disease conditions are associated with chronic intestinal disorders or enteropathies that are characterized by intestinal inflammation, increased gut permeability, and reduced capacity to absorb nutrients. Such disruptions in the homeostasis of the gastrointestinal (GI) tract can lead to symptoms of abdominal pain and discomfort, bloating, abnormal bowel function, and malabsorption of nutrients. While significant advances have been made in understanding the factors that influence the complex and fragile balance between the gut microbiota, intestinal epithelial cell integrity, and the underlying immune system, effective therapies for restoring intestinal balance during enteropathy are still not available. Numerous studies have demonstrated the ability of oral immunoglobulins to improve weight gain, support gut barrier function, and reduce the severity of enteropathy in animals. More recently, studies in humans provide evidence that serum-derived bovine immunoglobulin/protein isolate is safe and improves nutritional status and GI symptoms in patients with enteropathy associated with irritable bowel syndrome or infection with the human immunodeficiency virus. This review summarizes studies showing the impact of enteropathy on nutritional status and how specially formulated bovine immunoglobulins may help restore intestinal homeostasis and nutritional status in patients with specific enteropathies. Such protein preparations may provide distinct nutritional support required for the dietary management of patients who, because of therapeutic or chronic medical needs, have limited or impaired capacity to digest, absorb, or metabolize ordinary foodstuffs or certain nutrients, or other special medically determined nutrient requirements that cannot be satisfied by changes to the normal diet alone.

    Surgery is indicated when gastro-oesophageal reflux disease (GORD) is resistant to medical treatment. Manometry, upper GI series, pH-metry, gastric emptying studies and gastric acid sampling are performed in order to demonstrate that GORD is caused by a deficient gastro-oesophageal valve mechanism, and hence that surgical treatment will be beneficial. The surgical principle is restoring an anti-reflux barrier by recreating a sufficient pressure gradient in the distal oesophagus, and by correcting the gastro-oesophageal Hiss. Nissen' fundoplication is probably the most efficient anti-reflux procedure. However, it can cause dysphagia, gas bloating and inability to burp. One hundred and fifty-six laparoscopic Nissen fundoplications have been performed by the author. Operating time average 120 min. No perioperative death was observed. There were 3 conversions to laparotomy and 4 peroperative complications: 1 gastric perforation, 2 lesions of the pleura and 1 liver laceration. Four postoperative complications occurred: 1 pneumonia, 1 necrosis of the wrap, 1 small bowel perforation and 1 obstruction due to migration of the entire stomach into the chest. Hospitalisation time ranged between 2 and 14 days (median 2), with a follow up of a median of 10 months. Long-term postoperative complications were: 1 recurrent heartburn 6 months postoperatively and 2 severe dysphagia. PMID:8191168

    Complications and side effects following laparoscopic antireflux procedures are common. This article describes an alternative laparoscopic technique to prevent gastroesophageal reflux. This method consists of posterior approximation of the diaphragmatic crura followed by a posterior fundoplication of approximately 270 degrees wrap. In avoiding the 360 degree wrap and obtaining length from the longitudinal axis of the stomach, it is not necessary to take down the gastrosplenic vessels. The principle of the procedure is to accentuate the cardioesophageal angle of His. No sutures are placed in the esophagus. While this article primarily concerns technique, it also constitutes a brief report on the first 50 patients who have been followed up for 1 year or more. All patients but one are free of reflux symptoms and have discontinued taking all medication. There has been no dysphagia to liquids, and solid food dysphagia has not lasted >1 month. Bloating from gas is minimal, as most patients are able to burp early in their recovery. An outcome paper describing preoperative and postoperative objective testing and evaluation is in process.

    Full Text Available Abstract Background Nissen Fundoplication is a common surgical procedure performed in treating gastroesophageal reflux disease (GERD. Complications include dysphagia, gastric hypersensitivity, abnormal gastric motility, gas bloat syndrome and GERD relapse. Dumping syndrome may occur when a large volume of gastric content is delivered to the duodenum or jejunum, resulting in both gastrointestinal and vasomotor symptoms. Occasionally, dumping syndrome may be a complication in patients that have undergone nissen Fundoplication, especially in adults. The BreathID® continuous online 13C-Octanoicoctanoic acid breath test detects variations of less than 1/100,000 in the 13CO2/12CO2 ratio in exhaled air. Case presentation We report a case of a 38 year old male who was admitted and diagnosed with dumping syndrome following nissen Fundoplication, who was diagnosed using the BreathID® continuous online 13C-Octanoic acid breath test. Conclusions Early performance of a gastric emptying rate breath test in symptomatic patients, following upper GI tract surgery may help in the prediction or diagnosis of nissen Fundoplication complications such as dumping syndrome.

  12. Stoneware tile manufacturing using rice straw ash as feldspar replacement

    International Nuclear Information System (INIS)

    In this research are presented the results of using rice straw ash (RSA) in low proportions as substitute of feldspar for manufacturing stoneware tiles. Specimens of semidry triaxial mixtures, where feldspar was substituted for different percentages (25 % and 50 %) of RSA, were prepared by uniaxial pressing, followed by drying and sintering. Physical and mechanical properties of sintered bodies were evaluated. Porcelain stoneware tile specimens C0 and CF25 reached bending strength and water absorption values were in accordance with standard ISO 13006 (Annex G, BIa) ( ≥ 35 MPa and ≤ 0.5 %, respectively). However, in porcelain stoneware tile specimens CF50 due to bloating phenomenon was not possible obtain commercial tiles in accordance with standard ISO 13006. By using Scanning Electron Microscopy (SEM) needles of primary and secondary mullite were identified in a vitreous phase; and by using X-Ray Diffraction (XRD) mullite and quartz phases were identified. It was concluded that feldspar can be substituted positively by RSA in stoneware tile pastes. (Author)

  13. Theoretical Developments in Understanding Massive Star Formation

    Except under special circumstances massive stars in galactic disks will form through accretion. The gravitational collapse of a molecular cloud core will initially produce one or more low-mass quasi-hydrostatic objects of a few Jupiter masses. Through subsequent accretion the masses of these cores grow as they simultaneously evolve toward hydrogen-burning central densities and temperatures. We review the evolution of accreting (proto-)stars, including new results calculated with a publicly available stellar evolution code written by the authors. The evolution of accreting stars depends strongly on the accretion history. We find that for the high accretion rates considered, ˜10^{-3} M_⊙yr^{-1}, stars of ˜5-10 M_⊙ tend to bloat up to radii which may exceed 100 R_⊙. Because of the high rate of binarity among massive stars, we expect that these large radii during short phases of evolution will result in mass transfer, common envelope evolution, and a higher number of tight binaries with periods of a few days.

    In 2011, Bailes et al. reported on the discovery of a detached companion in a 131 minute orbit around PSR J1719-1438, a 173 Hz millisecond pulsar. The combination of the very low mass function and such a short orbital period is unique. The discoverers suggested that the progenitor system could be an ultracompact X-ray binary (UCXB), which is a binary with a sub-hour orbital period in which a (semi-)degenerate donor fills its Roche lobe and transfers mass to a neutron star. The standard gravitational-wave driven UCXB scenario, however, cannot produce a system like PSR J1719-1438 as it would take longer than the age of the Universe to reach an orbital period of 131 min. We investigate two modifications to the standard UCXB evolution that may resolve this discrepancy. The first involves significant heating and bloating of the donor by pulsar irradiation, and in the second modification the system loses orbital angular momentum via a fast stellar wind from the irradiated donor, additional to the losses via the usu...

    MtPAR (Medicago truncatula proanthocyanidin regulator) is an MYB family transcription factor that functions as a key regulator of proanthocyanidin (PA) biosynthesis in the model legume Medicago truncatula. MtPAR expression is confined to the seed coat, the site of PA accumulation. Loss-of-function par mutants contained substantially less PA in the seed coat than the wild type, whereas levels of anthocyanin and other specialized metabolites were normal in the mutants. In contrast, massive accumulation of PAs occurred when MtPAR was expressed ectopically in transformed hairy roots of Medicago. Transcriptome analysis of par mutants and MtPAR-expressing hairy roots, coupled with yeast one-hybrid analysis, revealed that MtPAR positively regulates genes encoding enzymes of the flavonoid-PA pathway via a probable activation of WD40-1. Expression of MtPAR in the forage legume alfalfa (Medicago sativa) resulted in detectable levels of PA in shoots, highlighting the potential of this gene for biotechnological strategies to increase PAs in forage legumes for reduction of pasture bloat in ruminant animals.

  16. DIRECT DIAGNOSTICS OF FORMING MASSIVE STARS: STELLAR PULSATION AND PERIODIC VARIABILITY OF MASER SOURCES

    International Nuclear Information System (INIS)

    The 6.7 GHz methanol maser emission, a tracer of forming massive stars, sometimes shows enigmatic periodic flux variations over several 10-100 days. In this Letter, we propose that these periodic variations could be explained by the pulsation of massive protostars growing under rapid mass accretion with rates of M-dot*∼>10-3 M☉ yr-1. Our stellar evolution calculations predict that the massive protostars have very large radii exceeding 100 R☉ at maximum, and here we study the pulsational stability of such bloated protostars by way of the linear stability analysis. We show that the protostar becomes pulsationally unstable with various periods of several 10-100 days depending on different accretion rates. With the fact that the stellar luminosity when the star is pulsationally unstable also depends on the accretion rate, we derive the period-luminosity relation log (L/ L☉) = 4.62 + 0.98log (P/100 days), which is testable with future observations. Our models further show that the radius and mass of the pulsating massive protostar should also depend on the period. It would be possible to infer such protostellar properties and the accretion rate with the observed period. Measuring the maser periods enables a direct diagnosis of the structure of accreting massive protostars, which are deeply embedded in dense gas and are inaccessible with other observations.

    We confirm the planetary nature of Kepler-412b, listed as planet candidate KOI-202 in the Kepler catalog, thanks to our radial velocity follow-up program of Kepler-released planet candidates, which is on going with the SOPHIE spectrograph. We performed a complete analysis of the system by combining the Kepler observations from Q1 to Q15, to ground-based spectroscopic observations that allowed us to derive radial velocity measurements, together with the host star parameters and properties. We also analyzed the light curve to derive the star's rotation period and the phase function of the planet, including the secondary eclipse. We found the planet has a mass of 0.939 $\\pm$ 0.085 M$_{Jup}$ and a radius of 1.325 $\\pm$ 0.043 R$_{Jup}$ which makes it a member of the bloated giant subgroup. It orbits its G3 V host star in 1.72 days. The system has an isochronal age of 5.1 Gyr, consistent with its moderate stellar activity as observed in the Kepler light curve and the rotation of the star of 17.2 $\\pm$ 1.6 days. Fro...

    2015-01-01

    Full Text Available ABSTRACT:Abomasal bloat associated with Sarcina genus bacteria is a rare condition reported in young ruminants. An outbreak characterized by the sudden death of eight lambs from a total of 80 lambs (30 days-old occurred on a property located in the city of Palmares do Sul in the state of Rio Grande do Sul. Deaths began to occur after the introduction of supplementation into the diet of lambs. At necropsy, the abomasum was distended by gas and had diffusely thickened walls and emphysema. On microscopic examination, the abomasum showed marked diffuse emphysema and multifocal areas of mild superficial necrosis with many coccoid structures measuring approximately 2µm in diameter, arranged in tetrads, compatible with Sarcina genus bacteria. After removing supplementation from the diet, no more deaths occurred. The diagnosis of this case was established by gross and microscopic lesions in addition to the clinical and epidemiological findings. Therefore, it was concluded that it was an outbreak of emphysematous abomasitis by Sarcina genus bacteria in lambs.

  19. TWO NEW TIDALLY DISTORTED WHITE DWARFS

    International Nuclear Information System (INIS)

    We identify two new tidally distorted white dwarfs (WDs), SDSS J174140.49+652638.7 and J211921.96–001825.8 (hereafter J1741 and J2119). Both stars are extremely low mass (ELM, ≤ 0.2 M☉) WDs in short-period, detached binary systems. High-speed photometric observations obtained at the McDonald Observatory reveal ellipsoidal variations and Doppler beaming in both systems; J1741, with a minimum companion mass of 1.1 M☉, has one of the strongest Doppler beaming signals ever observed in a binary system (0.59% ± 0.06% amplitude). We use the observed ellipsoidal variations to constrain the radius of each WD. For J1741, the star's radius must exceed 0.074 R☉. For J2119, the radius exceeds 0.10 R☉. These indirect radius measurements are comparable to the radius measurements for the bloated WD companions to A-stars found by the Kepler spacecraft, and they constitute some of the largest radii inferred for any WD. Surprisingly, J1741 also appears to show a 0.23% ± 0.06% reflection effect, and we discuss possible sources for this excess heating. Both J1741 and J2119 are strong gravitational wave sources, and the time-of-minimum of the ellipsoidal variations can be used to detect the orbital period decay. This may be possible on a timescale of a decade or less.

    The optical to near-infrared (300 - 2500 nm) spectrum of the candidate massive Young Stellar Object (YSO) B275, embedded in the star forming region M17, has been observed with X-shooter on the ESO Very Large Telescope. The spectrum includes both photospheric absorption lines and emission features (H and Ca triplet emission lines, 1st and 2nd overtone CO bandhead emission), as well as an infrared excess indicating the presence of a (flaring) circumstellar disk. The strongest emission lines are double-peaked with a peak separation ranging between 70 and 105 km s^-1 and provide information on the physical structure of the disk. The underlying photospheric spectrum is classified as B6-B7, significantly cooler than a previous estimate based on modeling of the spectral energy distribution. This discrepancy is solved by allowing for a larger stellar radius (i.e. a bloated star), and thus positioning the star above the main sequence. This constitutes the first firm spectral classification of an early-B pre-main-seque...

    2011-01-01

    I review what we know about the donor stars in cataclysmic variables (CVs), focusing particularly on the close link between these binary components and the overall secular evolution of CVs. I begin with a brief overview of the "standard model" of CV evolution and explain why the key observables this model is designed to explain - the period gap and the period minimum -- are intimately connected to the properties of the secondary stars in these systems. CV donors are expected to be slightly inflated relative to isolated, equal-mass main-sequence (MS) stars, and this "donor bloating" has now been confirmed observationally. The empirical donor mass-radius relationship also shows a discontinuity at M_2 = 0.2 M_sun which neatly separates long- and short-period CVs. This is strong confirmation of the basic disrupted magnetic braking scenario for CV evolution. The empirical M_2-R_2 relation can be combined with stellar models to construct a complete, semi-empirical donor sequence for CVs. This sequence provides all ...

  2. WASP-17b: AN ULTRA-LOW DENSITY PLANET IN A PROBABLE RETROGRADE ORBIT

    International Nuclear Information System (INIS)

    We report the discovery of the transiting giant planet WASP-17b, the least-dense planet currently known. It is 1.6 Saturn masses, but 1.5-2 Jupiter radii, giving a density of 6%-14% that of Jupiter. WASP-17b is in a 3.7 day orbit around a sub-solar metallicity, V = 11.6, F6 star. Preliminary detection of the Rossiter-McLaughlin effect suggests that WASP-17b is in a retrograde orbit (λ ∼ -1500), indicative of a violent history involving planet-planet or star-planet scattering. WASP-17b's bloated radius could be due to tidal heating resulting from recent or ongoing tidal circularization of an eccentric orbit, such as the highly eccentric orbits that typically result from scattering interactions. It will thus be important to determine more precisely the current orbital eccentricity by further high-precision radial velocity measurements or by timing the secondary eclipse, both to reduce the uncertainty on the planet's radius and to test tidal-heating models. Owing to its low surface gravity, WASP-17b's atmosphere has the largest scale height of any known planet, making it a good target for transmission spectroscopy.

    We report on Keck and Hubble Space Telescope optical observations of the eclipsing binary pulsar system PSR B1718-19, in the direction of the globular cluster NGC 6342. These reveal a faint star ($m_{\\rm F702W}=25.21\\pm0.07$; Vega system) within the pulsar's 0\\farcs5 radius positional error circle. This may be the companion. If it is a main-sequence star in the cluster, it has radius by accretion or newly formed) and its companion are initially in an eccentric orbit. If so, for tidal circularization to have produced the present-day highly circular orbit, a large stellar radius is required, i.e., the star must be bloated. Using constraints on the radius and temperature from the Roche and Hayashi limits, we infer from our observations that $\\rcomp\\simlt0.44 \\rsun$ and $\\teff\\simgt3300 $K. Even for the largest radii, the required efficiency of tidal dissipation is larger than expected for some prescriptions.

  4. Normal tissue tolerance to external beam radiation therapy: Small bowel

    International Nuclear Information System (INIS)

    The small bowel is a hollow organ involved in the transit and absorption of food. In relation to its anatomical location, a significant amount of this organ is exposed in whole or in part to ionizing radiation in external radiotherapy during abdominal or pelvic irradiation either for primary cancers or metastasis. The acute functional changes during external beam radiation are mainly leading to diarrhea, abdominal pain and bloating. The main late side effects of irradiation of the small intestine are chronic diarrhea, malabsorption with steatorrhoea, abdominal spasms, intestinal obstruction, bleeding and fistulas. The architecture of the small intestine may be considered as parallel with a significant correlation between the irradiated volume of small bowel and the likelihood of acute toxicity, whatever the dose. The literature analysis recommends to consider the volume of small bowel receiving 15 Gy (threshold of 100 to 200 cm3) but also 30 and 50 Gy (thresholds of 35 to 300 cm3, depending on the level of dose considered). Modern techniques of conformal radiotherapy with modulated intensity will probably have beneficial impact on small bowel toxicity. (authors)

  5. Crohn's disease in a Saudi outpatient population: Is it still rare?

    International Nuclear Information System (INIS)

    To determine the epidemiology of Crohn's disease (CD) in an outpatient clinic and compare it with data previously reported from different centers in the Kingdom of Saudi Arabia and outside. The medical records of all patients with CD seen in the clinic in the period from January 1993 through December 2007 were reviewed. The demographic, clinical data and methods of diagnosis were retrieved. Over a period of 15 years, we saw 133 Saudi patients with CD. They were predominantly young, with a median age of 26.2 years and male preponderance (2.3:1). The final diagnosis was established within 1 week of presentation in 47% of the patients. The leading symptoms were abdominal pain (88%), diarrhea (70%), bloating (61%), rectal bleeding (50%), weight loss (33%), constipation (24%) and perianal disease (23%). The diagnosis was established by endoscopy and histopathology. Ileocecal involvement was encountered in 40% of the patients. From the current study, it is obviously possible to diagnose a large proportion of patients with CD in a gastroenterology outpatient clinic. The data revealed a strikingly increased incidence of CD in a mainly young Saudi population in the past few years. (author)

  7. Spatially resolved charge-state and current-density distributions at the extraction of an electron cyclotron resonance ion source

    International Nuclear Information System (INIS)

    In this paper we present our measurements of charge-state and current-density distributions performed in very close vicinity (15 mm) of the extraction of our hexapole geometry electron cyclotron resonance ion source. We achieved a relatively high spatial resolution reducing the aperture of our 3D-movable extraction (puller) electrode to a diameter of only 0.5 mm. Thus, we are able to limit the source of the extracted ion beam to a very small region of the plasma electrode's hole (O = 4 mm) and therefore to a very small region of the neutral plasma sheath. The information about the charge-state distribution and the current density in the plane of the plasma electrode at each particular position is conserved in the ion beam. We determined the total current density distribution at a fixed coaxial distance of only 15 mm to the plasma electrode by remotely moving the small-aperture puller electrode which contained a dedicated Faraday cup (FC) across the aperture of the plasma electrode. In a second measurement we removed the FC and recorded m/q-spectra for the different positions using a sector magnet. From our results we can deduce that different ion charge-states can be grouped into bloated triangles of different sizes and same orientation at the extraction with the current density peaking at centre. This confirms observations from other groups based on simulations and emittance measurements. We present our measurements in detail and discuss possible systematic errors.

    Gastric necrosis is a rare condition because of the rich blood supply and the extensive submucosal vascular network of the stomach. "Gas-bloat" syndrome is a well known Nissen fundoplication postoperative complication. It may cause severe gastric dilatation, but very rarely an ischemic compromise of the organ. Other factors, such as gastric outlet obstruction, may concur to cause an intraluminal pressure enough to blockade venous return and ultimately arterial blood supply and oxygen deliver, leading to ischaemia. We report a case of a 63-year-old women, who presented a total gastric necrosis following laparoscopic Nissen fundoplication and a pyloric phytobezoar which was the trigger event. No preexisting gastric motility disorders were present by the time of surgery, as demonstrated in the preoperative barium swallow, thus a poor mastication (patient needed no dentures) of a high fiber meal (cabbage) may have been predisposing factors for the development of a bezoar in an otherwise healthy women at the onset of old age. A total gastrectomy with esophagojejunostomy was performed and patient was discharged home after a 7-d hospital stay with no immediate complications. We also discuss some technical aspects of the procedure that might be important to reduce the incidence of this complication. PMID:25276288

  9. ON THE SIMULTANEOUS EVOLUTION OF MASSIVE PROTOSTARS AND THEIR HOST CORES

    International Nuclear Information System (INIS)

    Studies of the evolution of massive protostars and the evolution of their host molecular cloud cores are commonly treated as separate problems. However, interdependencies between the two can be significant. Here, we study the simultaneous evolution of massive protostars and their host molecular cores using a multi-dimensional radiation hydrodynamics code that incorporates the effects of the thermal pressure and radiative acceleration feedback of the centrally forming protostar. The evolution of the massive protostar is computed simultaneously using the stellar evolution code STELLAR, modified to include the effects of variable accretion. The interdependencies are studied in three different collapse scenarios. For comparison, stellar evolutionary tracks at constant accretion rates and the evolution of the host cores using pre-computed stellar evolutionary tracks are computed. The resulting interdependencies of the protostellar evolution and the evolution of the environment are extremely diverse and depend on the order of events, in particular the time of circumstellar accretion disk formation with respect to the onset of the bloating phase of the star. Feedback mechanisms affect the instantaneous accretion rate and the protostar's radius, temperature, and luminosity on timescales t ≤ 5 kyr, corresponding to the accretion timescale and Kelvin-Helmholtz contraction timescale, respectively. Nevertheless, it is possible to approximate the overall protostellar evolution in many cases by pre-computed stellar evolutionary tracks assuming appropriate constant average accretion rates

    An outbreak of an acute disease in buffalo (Bubalus bubalis) caused by the ingestion of Baccharis megapotamica var. weirii occurred in the southern region of Brazil. Ten out of 50 buffalo died 24-48 hr after being introduced into a pasture containing abundant amounts of the plant. Factors influencing the ingestion of the plant and consequent toxicosis included hunger, stress caused by shipment, and unfamiliarity with the plant. Clinical signs included serous ocular discharge, incoordination, mild bloat, and muscle trembling. One buffalo was necropsied. Gross findings included dehydration, abundant liquid in the rumen, reddening of the mucosa of forestomachs, abomasum, and intestine, and edema of the wall of the rumen. The main histologic lesions were superficial to full thickness degeneration and necrosis of the stratified epithelium lining the forestomachs, necrosis of the intestinal mucosa, and widespread lymphoid necrosis. A calf (Bos taurus) was fed a single dose of 5 g/kg/body weight of B. megapotamica var. weirii harvested from the same site where the buffalo died. Twenty hours after the administration of the plant this calf died with clinical signs and lesions similar to those observed in the naturally poisoned buffalo. PMID:21908301

    Associative conditioning of satiety indicates that concentrated maltodextrin (cMD) may induce a mildly aversive visceral signal within 20 min of its ingestion, as well as satiating normally. Individuals' awareness of this adverse state was tested on ratings of statistically distinct descriptions of factors liable to suppress hunger, whether distressing or comfortably satisfying. Wanted amount of a food and the pleasantness of eating it correlated highly for each of five foods, once again refuting the widespread presumption that "pleasant" refers to sensory pleasure; hence, as in previous reports, suppression of hunger was measured as a reduction of the averaged pleasantness of functionally related foods. At 20 min after the start of ingestion of a small meal on a near-empty stomach, cMD reliably reduced hunger. The greatest influence on hunger, besides normal sating, was thirst, but there were also tendencies to nausea and bloat, although all less than after a full sized meal. Visceral processes shortly after a meal can create dissociable conscious states, only one of which is satiety for food. PMID:21118700

    The characterization of four new transiting extrasolar planets is presented here. KOI-188b and KOI-195b are bloated hot Saturns, with orbital periods of 3.8 and 3.2 days, and masses of 0.25 and 0.34 M_Jup, respectively. They are located in the low-mass range of known transiting, giant planets. KOI-192b has a similar mass (0.29 M_Jup) but a longer orbital period of 10.3 days. This places it in a domain where only few planets are known. KOI-830b, finally, with a mass of 1.27 M_Jup and a period of 3.5 days, is a typical hot Jupiter. The four planets have radii of 0.98, 1.09, 1.2, and 1.08 R_Jup, respectively. We detected no significant eccentricity in any of the systems, while the accuracy of our data does not rule out possible moderate eccentricities. The four objects were first identified by the Kepler Team as promising candidates from photometry of the Kepler satellite. We establish here their planetary nature thanks to the radial velocity follow-up we secured with the HARPS-N spectrograph at the Telescopio N...

    Decomposition is a dynamic ecological process dependent upon many factors such as environment, climate, and bacterial, insect, and vertebrate activity in addition to intrinsic properties inherent to individual cadavers. Although largely attributed to microbial metabolism, very little is known about the bacterial basis of human decomposition. To assess the change in bacterial community structure through time, bacterial samples were collected from several sites across two cadavers placed outdoors to decompose and analyzed through 454 pyrosequencing and analysis of variable regions 3-5 of the bacterial 16S ribosomal RNA (16S rRNA) gene. Each cadaver was characterized by a change in bacterial community structure for all sites sampled as time, and decomposition, progressed. Bacteria community structure is variable at placement and before purge for all body sites. At bloat and purge and until tissues began to dehydrate or were removed, bacteria associated with flies, such as Ignatzschineria and Wohlfahrtimonas, were common. After dehydration and skeletonization, bacteria associated with soil, such as Acinetobacter, were common at most body sites sampled. However, more cadavers sampled through multiple seasons are necessary to assess major trends in bacterial succession. PMID:25431049

    Domestic pets are commonly found in the homes of decedents whose deaths are investigated by a medical examiner or coroner. When these pets become trapped with a decomposing decedent they may resort to feeding on the body or succumb to starvation and/or dehydration and begin to decompose as well. In this case report photographic documentation of cases involving pets and decedents were examined from 2009 through the beginning of 2014. This photo review indicated that in many cases the pets were cats and dogs that were trapped with the decedent, died and were discovered in a moderate (bloat to active decay) state of decomposition. In addition three cases involving decomposing humans and their decomposing pets are described as they were processed for time of insect colonization by forensic entomological approach. Differences in timing and species colonizing the human and animal bodies were noted as was the potential for the human or animal derived specimens to contaminate one another at the scene.

  16. Mathematical modelling of densification during final stage of viscous flow sintering in ceramics

    International Nuclear Information System (INIS)

    A model is developed based on the original work of Mackenize and Shuttle worth in 1949 and the simplification of Kingery st al. in 1976, for densification during final stage sintering with the aid of a liquid phase (melt). The final equation of the model relates true porosity (P) to temperature (T) and time (t) by In (p/P sub 0)) = -(M.t/T)exp(-A/T) where P sub 0 is the original porosity and two constant A and M are evaluated by two measurement P sub 1 and P sub 2 at two temperatures T sub 1 and T sub 2 respectively. P vs T is shown to be a linear plot during bloating in over fired region. The intersection of this linear plot with the plot of model gives the best temperature of firing for the best densification. Despite complexities in sintering, this simple model, which can easily be applied in engineering systems, is practically evaluated in white ware bodies and has been found satisfactory. (author)

  17. Explorations into the Viability of Coupled Radius-Orbit Evolutionary Models for Inflated Planets

    Ibgui, Laurent; Burrows, Adam

    2009-01-01

    The radii of some transiting extrasolar giant planets are larger than would be expected by the standard theory. We address this puzzle with the model of coupled radius-orbit tidal evolution developed by \\citet{Ibgui_and_Burrows_2009}. The planetary radius is evolved self-consistently with orbital parameters, under the influence of tidal torques and tidal dissipation in the interior of the planet. A general feature of this model, which we have previously demonstrated in the generic case, is that a possible transient inflation of the planetary radius can temporarily interrupt its standard monotonic shrinking and can lead to the inflated radii that we observe. In particular, a bloated planet with even a circular orbit may still be inflated due to an earlier episode of tidal heating. We have modified our model to include an orbital period dependence of the tidal dissipation factor in the star, $Q'_{\\ast} \\propto P^{\\gamma}$, $-1 \\leqslant \\gamma \\leqslant 1$. With this model, we search, for a tidally heated plane...

    Sainfoin (Onobrychis viciifolia Scop. Syn. Onobrychis sativa L.) is a bloat-safe forage crop with high levels of tannins, which is renowned for its medicinal qualities in grazing animals. Mutagenesis technique was applied to investigate the influence of gamma irradiation at 30, 60, 90, and 120 Gy on mitotic behavior, in vitro growth factors, phytochemical and nutritional constituents of sainfoin. Although a percentage of plant necrosis and non-growing seed were enhanced by irradiation increment, the germination speed was significantly decreased. It was observed that gamma irradiated seeds had higher value of crude protein and dry matter digestibility compared to control seeds. Toxicity of copper was reduced in sainfoin irradiated seeds at different doses of gamma rays. Anthocyanin content also decreased in inverse proportion to irradiation intensity. Accumulation of phenolic and flavonoid compounds was enhanced by gamma irradiation exposure in leaf cells. HPLC profiles differed in peak areas of the two important alkaloids, Berberine and Sanguinarine, in 120 Gy irradiated seeds compared to control seeds. There were positive correlations between irradiation dose and some abnormality divisions such as laggard chromosome, micronucleus, binucleated cells, chromosome bridge, and cytomixis. In reality, radiocytological evaluation was proven to be essential in deducing the effectiveness of gamma irradiation to induce somaclonal variation in sainfoin. PMID:25147870

    The objectives were to describe the pattern of losses through culling, sales of breeding stock, mortality, and disappearance, and to characterize the causes of mortality of cows and replacement heifers of breeding age from Western Canadian beef herds. Cows and replacement heifers from 203 herds were observed for a 1-year period starting June 1, 2001. Veterinarians examined dead animals on-farm using a standard postmortem protocol. The incidence of culling in cows and replacements heifers was 14.3 per 100 cow-years at risk, and the frequencies of sales for breeding stock, mortality, and cows reported missing per cow-years at risk were 4.0, 1.1, and 0.4, respectively. During the study, 355 animals died or were euthanized, 209 were examined postmortem, and the requested tissues were submitted for histopathologic examination from 184. A cause of death was determined for 70% (128/184) of the cows with complete gross postmortem and histopathologic examinations. Hardware disease (traumatic reticuloperitonitis), malignant neoplasia (cancer), calving-associated injury, rumen tympany (bloat), myopathy, and pneumonia accounted for 56% (72/128) of the animals where a cause of death was determined. Twenty-three other causes of death accounted for the remaining 44% (56/128). Factors relating to cow nutrition accounted for 25% of the deaths, emphasizing the importance of feeding management as a determinant of cow health in western Canada. PMID:19436634

    Grazing steers on winter wheat forage is routinely practiced in the Southern Great Plains of the US. Here, we investigated the dynamics in bacterial populations of both solid and liquid ruminal fractions of steers grazing on maturing wheat forage of changing nutritive quality. The relationship between bacterial diversity and fermentation parameters in the liquid fraction was also investigated. During the first 28 days, the wheat was in a vegetative phase with a relatively high crude protein content (CP; 21%), which led to the incidence of mild cases of frothy bloat among steers. Rumen samples were collected on days 14, 28, 56 and 76, separated into solid and liquid fractions and analyzed for bacterial diversity using 16S pyrotag technology. The predominant phyla identified were Bacteroidetes (59-77%) and Firmicutes (20-33%) across both ruminal fractions. Very few differences were observed in the rumen bacterial communities within solid and liquid fractions on day 14. However, by day 28, the relatively high CP content complemented a distinct bacterial and chemical composition of the rumen fluid that was characterized by a higher ratio (4:1) of Bacteroidetes:Firmicutes and a corresponding lower acetate:propionate (3:1) ratio. Further, a greater accumulation of biofilm (mucopolysaccharide complex) on day 28 was strongly associated with the abundance of Firmicutes lineages such as Clostridium, Ruminococcus, Oscillospira and Moryella (Pbloat-prone) and reproductive stages of wheat forage.

    This was a prospective study that evaluates subjective and objective patient parameters 3 months after full-thickness gastroplication. Forty-one patients with documented gastroesophageal reflux disease and persistent symptoms despite medical treatment, without radiologic visible hiatal hernia, were enrolled in the study and underwent endoscopic full-thickness gastroplication with one or more plicator implants. Evaluation of Gastrointestinal Quality of Life Index, symptoms typically related to reflux, gas bloat, and bowel dysfunction and esophageal manometry, and impedance-pH monitoring were performed at baseline and 3 months after the procedure. The mean Gastrointestinal Quality of Life Index score, and general and reflux-specific scores improved significantly (Pbloat-specific symptom scores and bowel dysfunction-specific symptom scores were reduced (P<0.05) on follow-up. The numbers of total, acid, proximal, upright, and recumbent reflux episodes were all reduced (P<0.01). Manometric data remained almost unchanged. DeMeester score reduced nonsignificantly (P<0.098). 21.6% of the patients were on proton-pump inhibitor medication on a daily basis after the procedure. There was only 1 postprocedure incident (bleeding) that required intervention. In conclusion, endoscopic full-thickness plication is a safe and well-tolerated procedure that significantly improves quality of life and eliminates gastroesophageal reflux disease symptoms in the majority of patients, without side effects seen after laparoscopic fundoplication.

  2. THE NASA-UC ETA-EARTH PROGRAM. II. A PLANET ORBITING HD 156668 WITH A MINIMUM MASS OF FOUR EARTH MASSES

    International Nuclear Information System (INIS)

    We report the discovery of HD 156668 b, an extrasolar planet with a minimum mass of MP sin i = 4.15 M+. This planet was discovered through Keplerian modeling of precise radial velocities from Keck-HIRES and is the second super-Earth to emerge from the NASA-UC Eta-Earth Survey. The best-fit orbit is consistent with circular and has a period of P = 4.6455 days. The Doppler semi-amplitude of this planet, K = 1.89 m s-1, is among the lowest ever detected, on par with the detection of GJ 581 e using HARPS. A longer period (P ∼ 2.3 years), low-amplitude signal of unknown origin was also detected in the radial velocities and was filtered out of the data while fitting the short-period planet. Additional data are required to determine if the long-period signal is due to a second planet, stellar activity, or another source. Photometric observations using the Automated Photometric Telescopes at Fairborn Observatory show that HD 156668 (an old, quiet K3 dwarf) is photometrically constant over the radial velocity period to 0.1 mmag, supporting the existence of the planet. No transits were detected down to a photometric limit of ∼3 mmag, ruling out transiting planets dominated by extremely bloated atmospheres, but not precluding a transiting solid/liquid planet with a modest atmosphere.

    We describe a framework to help clinicians think about health-related quality of life in their gastrointestinal (GI) patients. We introduce "GI distress" as a clinically relevant concept and explain how it may result from physical symptoms, cognitions, and emotions. The GI distress framework suggests that providers should divide GI physical symptoms into four categories: pain, gas/bloat, altered defecation, and foregut symptoms. We describe how these physical symptoms can be amplified by maladaptive cognitions, including external locus of control, catastrophizing, and anticipation anxiety. We suggest determining the level of embarrassment from GI symptoms and asking about stigmatization. GI patients may also harbor emotional distress from their illness and may exhibit visceral anxiety marked by hypervigilance, fear, and avoidance of GI sensations. Look for signs of devitalization, indicated by inappropriate fatigue. When appropriate, screen for suicidal ideations. Finally, we provide a list of high-yield questions to screen for these maladaptive cognitions and emotions, and explain how the GI distress framework can be used in clinical practice. PMID:21378758

  4. A long-term profile of patients with irritable bowel syndrome

    International Nuclear Information System (INIS)

    Objective: To evaluate the symptom profile, course and prognosis of patients with irritable bowel syndrome (IBS) over a 15 years period. Study Design: An observational study. Place and Duration of Study: Shifa International Hospital, Islamabad, Pakistan, from 1996 to 2011. Methodology: Patients diagnosed with IBS at the study centre were followed for their clinical features, course over the period of time, management and its results. Only those patients were included in the study who completed the follow-up period. Results: A total of 292 patients with mean age of 40.44 +- 13.69 years were inducted. There were 156 (53.4%) males and 136 (46.6%) females. Nearly all male and female patients had abdominal pain and bloating. However, constipation was seen in 79.4% females and 71.6 males. Diarrhea was seen in 46.5% females and 42.7% males. Both constipation and diarrhea were seen in 27.3% female and 15.6% males. A high number of patients had concomitant illnesses and a large proportion of them had sleep disturbances, exacerbations with stress and had food sensitivities. Conclusion: This longitudinal follow-up study showed that, in our setting, there were more males suffering from this illness; females had more constipation-dominant features. Prognosis over the course of illness was excellent in all patients. (author)

  5. Behavior of an unirradiated aluminum-clad uranium fuel element in a simulated failure experiment

    International Nuclear Information System (INIS)

    A mockup experiment was conducted to simulate a loss-of-coolant incident in the K-West reactor. The mockup assembly included a K-Reactor Zircaloy-2 process tubing with a KVN aluminum-clad metallic uranium fuel element. The assembly was induction heated to 8500C in flowing steam environment. Bloating of the element occurred. The friable Al/U reaction product and the surface of the U core were not pyrophoric, even under abrasion. However, the mockup assembly was not subjected to hydrogen and water vapor. The Zircaloy-2 tube showed evidence of embrittlement along the bottom. Accelerated corrosion and hydriding also occurred near the six o'clock position. The core was removed easily from the Zircaloy-2 tube. Steam corrosion of the U core was not obvious from metallography, and hydrogen contents were minimal. Metallography of the U core indicated remnants of the Al/U reaction layer adhering to the OD and ID surfaces. The reaction product appeared to be two-phase, probably UAl3 and eutectic. Reactions of Zircaloy-2 in molten 8001 aluminum were investigated at 8500C. After an induction period (approx. 5 min), the penetration rate was 2.7 mil/min (as-etched). Oxides of 85 mg/dm2 (5 x 6 microns) delayed the reaction only 3.5 min

  6. A Third Hot White Dwarf Companion Detected by Kepler

    Carter, Joshua A; Fabrycky, Daniel

    2010-01-01

    We have found a system listed in the Kepler Binary Catalog (3.273 day period; Prsa et al. 2010) that we have determined is comprised of a low-mass, thermally-bloated, hot white dwarf orbiting an A star of about 2.3 solar masses. In this work we designate the object, KIC 10657664, simply as KHWD3. We use the transit depth of ~0.66%, the eclipse depth of ~1.9%, and regular smooth periodic variations at the orbital frequency and twice the orbital frequency to analyze the system parameters. The smooth periodic variations are identified with the classical ellipsoidal light variation and illumination effects, and the newly utilized Doppler boosting effect. Given the measured values of R/a and inclination angle of the binary, both the ELV and DB effects are mostly sensitive to the mass ratio, q = M_2/M_1, of the binary. The two effects yield values of q which are somewhat inconsistent - presumably due to unidentified systematic effects - but which nonetheless provide a quite useful set of possibilities for the mass ...

    2011-01-01

    We report the detection of thermal emission at 4.5 and 8 micron from the planet WASP-17b. We used Spitzer to measure the system brightness at each wavelength during two occultations of the planet by its host star. By combining the resulting light curves with existing transit light curves and radial velocity measurements in a simultaneous analysis, we find the radius of WASP-17b to be 2.0 Rjup, which is 0.2 Rjup larger than any other known planet and 0.7 Rjup larger than predicted by the standard cooling theory of irradiated gas giant planets. We find the retrograde orbit of WASP-17b to be slightly eccentric, with 0.0012 < e < 0.070 (3 sigma). Such a low eccentricity suggests that, under current models, tidal heating alone could not have bloated the planet to its current size, so the radius of WASP-17b is currently unexplained. From the measured planet-star flux-density ratios we infer 4.5 and 8 micron brightness temperatures of 1881 \\pm 50 K and 1580 \\pm 150 K, respectively, consistent with a low-albedo...

  8. Pulsational instability of supergiant protostars: Do they grow supermassive by accretion?

    CERN Document Server

    Inayoshi, Kohei; Omukai, Kazuyuki

    2013-01-01

    Supermassive stars (SMSs; M>10^5 Msun) and their remnant black holes are promising progenitors for supermassive black holes (SMBHs) observed in the early universe at z>7. It has been postulated that SMSs forms through very rapid mass accretion onto a protostar at a high rate exceeding 0.01 Msun/yr. According to recent studies, such rapidly accreting protostars evolve into "supergiant protostars", i.e. protostars consisting of a bloated envelope and a contracting core, similar to giant star. However, like massive stars as well as giant stars, both of which are known to be pulsationally unstable, supergiant protostars may also be also unstable to launch strong pulsation-driven outflows. If this is the case, the stellar growth via accretion will be hindered by the mass loss. We here study the pulsational stability of the supergiant protostars in the mass range M600 Msun and very high accretion rate Mdot>1.0 Msun/yr are unstable due to the kappa mechanism. The pulsation is excited in the He^+ ionization layer in ...

    2012-01-01

    We identify two new tidally distorted white dwarfs (WDs), SDSS J174140.49+652638.7 and J211921.96-001825.8 (hereafter J1741 and J2119). Both stars are extremely low mass (ELM, < 0.2 Msun) WDs in short-period, detached binary systems. High-speed photometric observations obtained at the McDonald Observatory reveal ellipsoidal variations and Doppler beaming in both systems; J1741, with a minimum companion mass of 1.1 Msun, has one of the strongest Doppler beaming signals ever observed in a binary system (0.59 \\pm 0.06% amplitude). We use the observed ellipsoidal variations to constrain the radius of each WD. For J1741, the star's radius must exceed 0.074 Rsun. For J2119, the radius exceeds 0.10 Rsun. These indirect radius measurements are comparable to the radius measurements for the bloated WD companions to A-stars found by the Kepler spacecraft, and they constitute some of the largest radii inferred for any WD. Surprisingly, J1741 also appears to show a 0.23 \\pm 0.06% reflection effect, and we discuss possi...

    2012-01-01

    Ground-based simultaneous multiband transit observations allow an accurate system parameters determination and may lead to the detection and characterization of additional bodies via the transit timing variations (TTVs) method. We aimed to (i) characterize the heavily bloated WASP-4b hot Jupiter and its star by measuring system parameters and the dependence of the planetary radius as a function of four (Sloan g', r', i', z') wavelengths and (ii) search for TTVs. We recorded 987 images during three complete transits with the GROND instrument, mounted on the MPG/ESO-2.2m telescope at La Silla Observatory. Assuming a quadratic law for the stellar limb darkening we derive system parameters by fitting a composite transit light curve over all bandpasses simultaneously. To compute uncertainties of the fitted parameters, we employ the Bootstrap Monte Carlo Method. The three central transit times are measured with precision down to 6 s. We find a planetary radius Rp = 1.413+/-0.020 RJup, an orbital inclination i = 88d...

  11. Coarsening-densification transition temperature in sintering of uranium dioxide

    International Nuclear Information System (INIS)

    The concept of coarsening-densification transition temperature (CDTT) has been proposed to explain the experimental observations of the study of sintering undoped uranium dioxide and niobia-doped uranium dioxide powder compacts in argon atmosphere in a laboratory tubular furnace. The general method for deducing CDTT for a given material under the prevailing conditions of sintering and the likely variables that influence the CDTT are described. Though the present work is specific in nature for uranium dioxide sintering in argon atmosphere, the concept of CDTT is fairly general and must be applicable to sintering of any material and has immense potential to offer advantages in designing and/or optimizing the profile of a sintering furnace, in the diagnosis of the fault in the process conditions of sintering, and so on. The problems of viewing the effect of heating rate only in terms of densification are brought out in the light of observing the undesirable phenomena of coring and bloating and causes were identified and remedial measures suggested

  12. A theoretical light-curve model for the 1985 outburst of RS Ophiuchi

    CERN Document Server

    Hachisu, I; Hachisu, Izumi; Kato, Mariko

    2000-01-01

    A theoretical light-curve model of the 1985 outburst of RS Ophiuchi is presented based on a thermonuclear runaway (TNR) model. The system consists of a very massive white dwarf (WD) with an accretion disk (ACDK) and a red giant (RG). The early phase of the V light curve is well reproduced only by the bloated WD photosphere of the TNR model on a 1.35 +/- 0.01 M_sun WD while the later phase is dominated both by the irradiated ACDK and by the irradiated RG underfilling the inner critical Roche lobe. The UV light curve is also well reproduced by the same model with the distance of 0.6 kpc to RS Oph. The envelope mass at the optical peak is estimated to be 2 x 10^{-6} M_sun, indicating a rather high mass accretion rate of 1.2 x 10^{-7} M_sun yr^{-1} between the 1967 and the 1985 outbursts.

    In 2013, electronic documentation of clinical care stands at a crossroads. The benefits of creating digital notes are at risk of being overwhelmed by the inclusion of easily importable detail. Providers are the primary authors of encounters with patients. We must document clearly our understanding of patients and our communication with them and our colleagues. We want to document efficiently to meet without exceeding documentation guidelines. We copy and paste documentation, because it not only simplifies the documentation process generally, but also supports meeting coding and regulatory requirements specifically. Since the primary goal of our profession is to spend as much time as possible listening to, understanding and helping patients, clinicians need information technology to make electronic documentation easier, not harder. At the same time, there should be reasonable restrictions on the use of copy and paste to limit the growing challenge of 'note bloat'. We must find the right balance between ease of use and thoughtless documentation. The guiding principles in this document may be used to launch an interdisciplinary dialogue that promotes useful and necessary documentation that best facilitates efficient information capture and effective display.

    The very inner structure of massive YSOs is difficult to trace. With conventional observational methods we often identify structures still several hundreds of AU in size. But we also need information about the innermost regions where the actual mass transfer onto the forming high-mass star occurs. An innovative way to probe these scales is to utilise mid-infrared interferometry. Here, we present first results of our MIDI GTO programme at the VLTI. We observed 10 well-known massive YSOs down to scales of 20 mas. We clearly resolve these objects which results in low visibilities and sizes in the order of 30 - 50 mas. Thus, with MIDI we can for the first time quantify the extent of the thermal emission from the warm circumstellar dust and thus calibrate existing concepts regarding the compactness of such emission in the pre-UCHII region phase. Special emphasis will be given to the BN-type object M8E-IR where our modelling is most advanced and where there is indirect evidence for a strongly bloated central star.

  15. Direct diagnostics of forming massive stars: stellar pulsation and periodic variability of maser sources

    The 6.7 GHz methanol maser emission, a tracer of forming massive stars, sometimes shows enigmatic periodic flux variations over several 10-100 days. In this Letter, we propose that this periodic variations could be explained by the pulsation of massive protostars growing under rapid mass accretion with rates of Mdot > 10^-3 Msun/yr. Our stellar evolution calculations predict that the massive protostars have very large radius exceeding 100 Rsun at maximum, and we here study the pulsational stability of such the bloated protostars by way of the linear stability analysis. We show that the protostar becomes pulsationally unstable with various periods of several 10-100 days, depending on different accretion rates. With the fact that the stellar luminosity when the star is pulsationally unstable also depends on the accretion rate, we derive the period-luminosity relation log (L/Lsun) = 4.62 + 0.98log(P/100 day), which is testable with future observations. Our models further show that the radius and mass of the puls...

    Unspecific abdominal complaints including bloating and irregular bowel movements may be caused by carbohydrate malabsorption syndromes, e.g., lactose and fructose malabsorption. These symptoms were investigated with hydrogen (H2) breath tests and correlated to carbohydrate malabsorption. During performing these H2-breath tests the patient presented with an acute, localized, non-migratory pain in the left lower abdominal quadrant. Primary epiploic appendagitis is a rare cause of abdominal acute or subacute complaints and diagnosis of primary epiploic appendagitis (PEA) is made when computed tomography reveals a characteristic lesion. We report on a patient with co-occurrence of lactose and fructose malabsorption, which was treated successfully with a diet free of culprit carbohydrates, with PEA recovering without medication or surgical treatment within few days. Since the abdominal unspecific symptoms had been present for months, they appeared not to be correlated to the acute localized abdominal pain, therefore we speculate on a random co-occurrence of combined carbohydrate malabsorption and PEA.

  17. Celiac disease

    2006-03-01

    Full Text Available Abstract Celiac disease is a chronic intestinal disease caused by intolerance to gluten. It is characterized by immune-mediated enteropathy, associated with maldigestion and malabsorption of most nutrients and vitamins. In predisposed individuals, the ingestion of gluten-containing food such as wheat and rye induces a flat jejunal mucosa with infiltration of lymphocytes. The main symptoms are: stomach pain, gas, and bloating, diarrhea, weight loss, anemia, edema, bone or joint pain. Prevalence for clinically overt celiac disease varies from 1:270 in Finland to 1:5000 in North America. Since celiac disease can be asymptomatic, most subjects are not diagnosed or they can present with atypical symptoms. Furthermore, severe inflammation of the small bowel can be present without any gastrointestinal symptoms. The diagnosis should be made early since celiac disease causes growth retardation in untreated children and atypical symptoms like infertility or neurological symptoms. Diagnosis requires endoscopy with jejunal biopsy. In addition, tissue-transglutaminase antibodies are important to confirm the diagnosis since there are other diseases which can mimic celiac disease. The exact cause of celiac disease is unknown but is thought to be primarily immune mediated (tissue-transglutaminase autoantigen; often the disease is inherited. Management consists in life long withdrawal of dietary gluten, which leads to significant clinical and histological improvement. However, complete normalization of histology can take years.

    Celiac disease is a gastrointestinal disorder characterized by inflammation, leading to injury to the mucosal lining of the small intestine. The inflammation occurs when gliadin, a protein found in such gluten-containing foods as wheat, rye, and barley, is ingested by genetically susceptible individuals. The mucosal damage and subsequent malabsorption of nutrients leads to various complications. Researchers estimate that more than 2 million people in the United States have celiac disease-a prevalence that is greater than was previously believed. Approximately 60,000 Americans are diagnosed annually with celiac disease. Until recently, diagnosis has been complicated by the fact that the indicators of celiac disease are nonspecific. However, because of the development of new, easy-to-administer serology tests, diagnosis has become much less complicated. After conducting a review of the literature, the authors recommend a serologic testing sequence for diagnosis of celiac disease and urge that adults and children with an assortment of symptoms be tested for this disease. Common signs and symptoms of celiac disease include anemia, arthralgia, fatigue, infertility, neuropathy, and weight loss, in addition to such gastrointestinal symptomatology as abdominal pain, anorexia, bloating, constipation, and diarrhea. The only treatment for patients with celiac disease remains a gluten-free diet. PMID:16585382

  19. A review of the role of the gut microflora in irritable bowel syndrome and the effects of probiotics.

    2002-09-01

    Irritable bowel syndrome (IBS) is a multi-factorial gastrointestinal condition affecting 8-22 % of the population with a higher prevalence in women and accounting for 20-50 % of referrals to gastroenterology clinics. It is characterised by abdominal pain, excessive flatus, variable bowel habit and abdominal bloating for which there is no evidence of detectable organic disease. Suggested aetiologies include gut motility and psychological disorders, psychophysiological phenomena and colonic malfermentation. The faecal microflora in IBS has been shown to be abnormal with higher numbers of facultative organisms and low numbers of lactobacilli and bifidobacteria. Although there is no evidence of food allergy in IBS, food intolerance has been identified and exclusion diets are beneficial to many IBS patients. Food intolerance may be due to abnormal fermentation of food residues in the colon, as a result of disruption of the normal flora. The role of probiotics in IBS has not been clearly defined. Some studies have shown improvements in pain and flatulence in response to probiotic administration, whilst others have shown no symptomatic improvement. It is possible that the future role of probiotics in IBS will lie in prevention, rather than cure. PMID:12215182

    Full Text Available Introduction. Primary duodenal adenocarcinoma is an infrequent tumor both in our environment and in the world. There is no conclusive evidence on its epidemiology, diagnostic criteria, treatment or prognosis. Clinical case. We report a 77 year-old female patient, of mixed racial origin, native of Cusco (Peru who consulted for abdominal pain, weight loss, nausea, postprandial vomiting and bloating of three months course. At the time of examination she had second to third degree protein malnutrition with a BMI of 16.88 kg/m2, signs of moderate to severe chronic anemia and an 8 cm abdominal tumor in the epigastrium and right hypochondrium. The multislice spiral abdominal CT and ultrasonography revealed the presence of a solid tumor in the second portion of the duodenum. The patient was submitted to a gastroenterostomy without tumor resection. Biopsy confirmed tubular adenocarcinoma. Furthermore, no other primary tumors were found in the stomach, pancreas, biliary tree and colon. The patient was stabilized and was treated with 5-fluorouracil, irinotecan and leucovorin. Literature review. The article includes a brief review on the diagnosis, treatment and prognosis of this condition. Discussion. Management is not straightforward. There is little literature on the subject leaving decisions up to the attending physician’s criteria. We believe that all cases of rare diseases should be studied in depth, give rise to a thorough review of literature and, above all, be brought to the attention of the medical community.

    Full Text Available A survey of the carrion fauna was made at two sites in Curitiba, State of Paraná, with the objective of describing the insects associated with carrion and setting up a preliminary data-base for medico-legal purposes in south Brazil. Vertebrate exclusion experiments were carried out in each season between 1994 and 1995 with a 250 g laboratory-bred rat (Rattus norvegicus. Five stages of decomposition were identified: fresh, bloated, decaying, dry and adipocere-like. Some species showed seasonal and site preference and so could be used to identify the probable place and season where death took place. Sarconesia chlorogaster (Diptera, Calliphoridae was restricted to an open field site and to cooler months. Hemilucilia semidiaphana (Diptera, Calliphoridae and Pattonella resona (Diptera, Sarcophagidae were restricted to the forest site and warmer months. Phaenicia eximia (Diptera, Calliphoridae and Oxyletrum discicolle (Coleoptera, Silphidae were present at both sites throughout the year and could be useful for population level analysis. Dissochaetus murray (Coleoptera, Cholevidae was present throughout the year at the forest site and was associated with the adipocere-like stage. Ants played an important role producing post-mortem injuries to the carcasses. Insects of 32 species are reported as being useful in community level approaches

  2. What is the evidence for the use of probiotics in functional disorders?

    2012-02-03

    A rationale for the use of probiotics for a number of functional gastrointestinal symptoms and syndromes can be developed, and an experimental basis for their use continues to emerge, but data from well-conducted clinical trials of probiotics in this area remain scarce. Irritable bowel syndrome (IBS) has attracted the most attention; recent revelations regarding the potential pathogenic roles of the enteric flora and immune activation have led to reawakened interest in bacterio-therapy for this common and challenging disorder. Some recent randomized, controlled studies attest to the efficacy of some probiotics in alleviating individual IBS symptoms, and selected strains have a more global impact. Evidence for long-term efficacy is also beginning to emerge, though more studies are needed in this regard. In other functional syndromes, data are far from adequate to make recommendations, but there is evidence for efficacy of probiotics in treating individual symptoms such as diarrhea, constipation, and bloating. The interpretation of much of the literature in this area is complicated by lack of quality control, use of many different species and strains, and, above all, significant deficiencies in trial methodology.

    2015-05-01

    Fasting in the month of Ramadan can improve a person's health, but if the correct diet is not followed, one is prone to acquire some ailments related to the digestive health. Dyspeptic symptoms are frequently encountered during Ramadan, with indigestion, bloating and heartburns being more common, particularly after eating too much at lftar or Suhur meals. Eating in moderation and elimination of foods that can trigger gastroesophageal reflux are helpful. Empiric therapy with a proton pump inhibitor (PPI) is recommended in this setting. Duodenal ulcers and duodenitis are more common during Ramadan and the frequency of complications of peptic ulcer is higher. Patients with duodenal ulcer treated with PPI may fast without any symptoms. Ramadan fasting does not impose serious risks on patients with inflammatory bowel disease. Chronic hepatitis patients show non-significant changes in the liver function tests. However, patients with advanced liver disease may decompensate. As gastrointestinal and liver ailments tend to be more common and severe in diabetics compared with the normal individuals, extra vigilance is needed for the people with diabetes who are allowed to fast by their physicians.

    AIM: To estimate the prevalence of small intestinal bacterial overgrowth (SIBO) in our geographical area (Western Sicily, Italy) by means of an observational study, and to gather information on the use of locally active, non-absorbable antibiotics for treatment of SIBO. METHODS: Our survey included 115 patients fulfilling the Rome II criteria for diagnosis of irritable bowel syndrome (IBS); a total of 97 patients accepted to perform a breath test with lactulose (BTLact), and those who had a positive test, received Rifaximin (Normix®, Alfa Wassermann) 1200 mg/d for 7 d; 3 wk after the end of treatment, the BTLact was repeated. RESULTS: Based on the BTLact results, SIBO was present in about 56% of IBS patients, and it was responsible for some IBS-related symptoms, such as abdominal bloating and discomfort, and diarrhoea. 1-wk treatment with Rifaximin turned the BTLact to negative in about 50% of patients and significantly reduced the symptoms, especially in those patients with an alternated constipation/diarrhoea-variant IBS. CONCLUSION: SIBO should be always suspected in patients with IBS, and a differential diagnosis is done by means of a “breath test”. Rifaximin may represent a valid approach to the treatment of SIBO.

    2015-01-01

    Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder characterized by recurrent abdominal pain and abnormal bowel patterns. Alteration in gut flora, visceral hypersensitivity, and abnormal bowel motility are among numerous factors in the complex pathophysiology of IBS. Antibiotics have been used adjunctively to treat IBS for many years but are associated with various systemic side effects. Rifaximin is a nonabsorbable, broad-spectrum antimicrobial that inhibits bacterial RNA synthesis by binding the β-subunit of microbial RNA polymerase. It targets the gastrointestinal tract and works by reducing the quantity of gas-producing bacteria and altering the predominant species of bacteria present. In vivo animal studies suggest additional beneficial mechanisms of rifaximin, including reducing mucosal inflammation and visceral hypersensitivity. Clinical studies have demonstrated that rifaximin improves symptoms associated with IBS, such as bloating, flatulence, stool consistency, and abdominal pain, and has a side-effect profile similar to placebo. Although additional investigation into optimal dosing, treatment duration, and potential resistance is required, rifaximin presents as a safe and beneficial addition to the current management options for IBS.

    Full Text Available Background: Bile gastritis (gastropathy is a kind of gastritis which is caused by reflux of bile contents through duodenum on stomach. It can occur spontaneously without any former gastric surgeries which affect sphincter of pylorus. The positive impact of some certain drugs such as prokinetic agents e.g. metoclopramide, Proton-pump inhibitors (PPIs, cholestyramine and sucralfate in treating bile gastritis has been confirmed. This study has been conducted in order to analyze the effect of ursodeoxycholic acid (UDCA, which is a harmless drug, on patients with the bile gastritis. Materials and Methods: In this clinical trial, all patients with dyspepsia who were qualified to undertake endoscopy were enrolled and then 60 patients with bile gastritis were selected for the study. The patients were divided into two groups; a group was treated by UDCA, omeprazole and sucralfate and another one was treated with placebo, omeprazole and sucralfate for two weeks. Finally, at the end of the third week of treatment patients were examined.Results: A total of sixty 19-70 year-old patients (Mean: 46 years old included in this study. At the end of the study, there was not found any meaningful difference between the two groups in terms of pain intensity, heartburn intensity, severity of bloating, vomiting and early satiety; however, each group independently showed improvement of the mentioned indices after termination of the treatment (p=0.0005.Conclusion: Adding UDCA to the standard treatment (sucralfate is not clinically effective in curing the bile gastritis.

    Full Text Available Objectives: To determine the prevalence of premenstrual symptoms (PMS due to primary dysmenorrhea among a sample of university female students, and to explore possible association with vitamin D and parathyroid (PTH levels, as well as frequency of consumption of dairy products. Design: A cross-sectional study. Setting: One Jordanian university. Subjects: A total of 177 female students aged between 18 and 24 years who experienced primary dysmenorrhea participated in the study and completed a self administered questionnaire to collect information concerning demographics, menstruation- related information, associated specified premenstrual symptoms, and consumption of dairy products. Plasma 25-hydroxyvitamin vitamin D level and intact parathyroid hormone level were measured. Results: Of the 177 participants 91.5% had two or more symptoms among which fatigue, mood swings, anxiety, abdominal bloating, and depression were the most prevalent symptoms. There was no evident association between presence of symptoms and vitamin D status, PTH level or dairy products consumption. Headaches and social withdrawal were significantly lower in those women who consumed high amounts of dairy products. Conclusion: Premenstrual symptoms are very common in young women with primary dysmenorrhea. PMS has no relation to levels of vitamin D, parathyroid hormone or dairy products consumption. Headache and social withdrawal may be affected by dairy product consumption.

    Full Text Available Abstract One hundred and fifteen patients with symptoms suggestive of irritable bowel syndrome (IBS according to Rome III criteria and 209 patients with gastrointestinal symptoms different from IBS (control were identified through medical records from the Gastroenterology Clinic of the "Dr. Manuel Gea Gonzalez General Hospital" from January 2008 to March 2010. No statistical differences in IBS data as compared with control groups were observed except in bloating, that was more frequent in the IBS group (P = 0.043. Although the pathogenicity of specific intestinal protozoa could not be demonstrated due to lack of association with the development of gastrointestinal symptoms, Blastocystis spp, in the IBS group, exhibited a trend of association to diarrhoea (odds ratio = 2.73, 95% confidence interval = 0.84-8.80, P = 0.053, while having any parasite and diarrhoea was significant (odds ratio = 3.38, 95% confidence interval = 1.33-8.57, P = 0.008. The association between Blastocystis and diarrhoea in IBS patients although not conclusive is an interesting finding; nonetheless more extensive case-controlled studies are required to clearly define the role of some "non-pathogenic" parasites in intestinal disease and IBS.

    In this research are presented the results of using rice straw ash (RSA) in low proportions as substitute of feldspar for manufacturing stoneware tiles. Specimens of semidry triaxial mixtures, where feldspar was substituted for different percentages (25 % and 50 %) of RSA, were prepared by uniaxial pressing, followed by drying and sintering. Physical and mechanical properties of sintered bodies were evaluated. Porcelain stoneware tile specimens C0 and CF25 reached bending strength and water absorption values were in accordance with standard ISO 13006 (Annex G, BIa) ( {>=} 35 MPa and {<=} 0.5 %, respectively). However, in porcelain stoneware tile specimens CF50 due to bloating phenomenon was not possible obtain commercial tiles in accordance with standard ISO 13006. By using Scanning Electron Microscopy (SEM) needles of primary and secondary mullite were identified in a vitreous phase; and by using X-Ray Diffraction (XRD) mullite and quartz phases were identified. It was concluded that feldspar can be substituted positively by RSA in stoneware tile pastes. (Author)

    Ovarian cancer represents one of the cancers with the worst prognostic in adult women. More than half of the patients who present with clinical signs such as abdominal bloating and a feeling of fullness already show advanced stages. The majority of ovarian cancers grow as cystic masses, and cancer cells easily spread into the pelvic cavity once the cysts rupture or leak. When the ovarian cancer cells disseminate into the peritoneal cavity, metastatic nests may grow in the cul-de-sac, and in more advanced stages, the peritoneal surfaces of the upper abdomen become the next largest soil for cancer progression. Ascites is also produced frequently in ovarian cancers, which facilitates distant metastasis. Clinicopathologic, epidemiologic and molecular studies on ovarian cancers have improved our understanding and therapeutic approaches, but still further efforts are required to reduce the risks in the patients who are predisposed to this lethal disease and the mortality of the patients in advanced stages. Among various molecules involved in ovarian carcinogenesis, special genes such as TP53, BRCA1 and BRCA2 have been well investigated. These genes are widely accepted as the predisposing factors that trigger malignant transformation of the epithelial cells of the ovary. In addition, adnexal inflammatory conditions such as chronic salpingitis and ovarian endometriosis have been great research interests in the context of carcinogenic background of ovarian cancers. In this review, I discuss the roles of stromal cells and inflammatory factors in the carcinogenesis and progression of ovarian cancers.

    Objective. Functional dyspepsia (FD) is a frequent clinical finding in western world. The aim of this study is to compare the efficacy of a ginger and artichoke supplementation versus placebo in the treatment of FD. Methods. A prospective multicentre, double blind, randomized, placebo controlled, parallel-group comparison of the supplement and placebo over a period of 4 weeks was performed. Two capsules/day were supplied (before lunch and dinner) to 126 FD patients (supplementation/placebo: 65/61). Results. After 14 days of treatment, only supplementation group (SG) showed a significant amelioration (SG: α S = +1.195 MCA score units (u), P = 0.017; placebo: α P = +0.347 u, P = 0.513). The intercept (α) resulted to be significantly higher in SG than in placebo (α S - α P = +0.848 u, P nausea (β S - β P = -0.398 u, P < 0.001), epigastric fullness (β S - β P = -0.241, P < 0.001), epigastric pain (β S - β P = -0.173 u, P = 0.002), and bloating (β S - β P = -0.167 u, P = 0.017). Conclusions. The association between ginger and artichoke leaf extracts appears safe and efficacious in the treatment of FD and could represent a promising treatment for this disease. PMID:25954317

  15. Densification of boron carbide at relatively low temperatures by hot pressing and hot isostatic pressing

    International Nuclear Information System (INIS)

    The poor sinterability of B4C limits its widespread application because both high temperatures and high pressures are required for a complete densification. Moreover, B4C suffers from a low strength and fracture toughness, possesses, however, a high potential because of its extreme hardness. Reaction hot pressing of B4C-WC-TiC-Si-Co mixtures resulting in B4C-TiB2-W2B5 composites of high density exhibit remarkable mechanical properties. The influence of hot isostatic pressing (HIP) on the microstructure and the mechanical properties is investigated in cooperation with participants of the COST 503 activities and related to the strengthening and toughening mechanisms. Difficulties during densification by HIP arise from the evaporation of adsorbed volatiles as well as from the strong swelling of the powder compact due to the sintering reaction. Several HIP cycle designs were tested in order to prevent the bloating of the capsule and to control internal stresses due to the misfit of the thermal expansion of the entire phases. In comparison to single phase B4C ceramics, bending strength was improved to 1030 MPa, KIc to 5.2 MPa/m, while hardness was comparable with HV1=38 GPa. Wear test were performed and related to the toughening mechanisms. (orig.) With 56 refs., 9 tabs., 64 figs

    Functional dyspepsia is a symptom complex characterised by upper abdominal discomfort or pain, early satiety,motor abnormalities, abdominal bloating and nausea in the absence of organic disease. The central nervous system plays an important role in the conducting and processing of visceral signals. Alterations in brain processing of pain, perception and affective responses may be key factors in the pathogenesis of functional dyspepsia. Central serotonergic and noradrenergic receptor systems are involved in the processing of motor,sensory and secretory activities of the gastrointestinal tract. Visceral hypersensitivity is currently regarded as the mechanism responsible for both motor alterations and abdominal pain in functional dyspepsia. Some studies suggest that there are alterations in central serotonergic and noradrenergic systems which may partially explain some of the symptoms of functional dyspepsia. Alterations in the autonomic nervous system may be implicated in the motor abnormalities and increases in visceral sensitivity in these patients.Noradrenaline is the main neurotransmitter in the sympathetic nervous system and again alterations in the functioning of this system may lead to changes in motor function. Functional dyspepsia causes considerable burden on the patient and society. The pathophysiology of functional dyspepsia is not fully understood but alterations in central processing by the serotonergic and noradrenergic systems may provide plausible explanations for at least some of the symptoms and offer possible treatment targets for the future.

  17. Medium-chain Triglyceride Ketogenic Diet, An Effective Treatment for Drug-resistant Epilepsy and A Comparison with Other Ketogenic Diets

    Full Text Available The ketogenic diet (KD is one of the most effective therapies for drug-resistant epilepsy. The efficacy of the medium-chain triglyceride KD (MCTKD is as excellent as the classic KD (CKD, which has been documented in several subsequent retrospective, prospective, and randomized studies. MCT oil is more ketogenic than long-chain triglycerides. Therefore, the MCTKD allows more carbohydrate and protein food, which makes the diet more palatable than the CKD. The MCTKD is not based on diet ratios as is the CKD, but uses a percentage of calories from MCT oil to create ketones. There has also been literature which documents the associated gastrointestinal side effects from the MCTKD, such as diarrhea, vomiting, bloating, and cramps. Therefore, the MCTKD has been an underutilized diet therapy for intractable epilepsy among children.The author has used up to >70% MCTKD diet to maximize seizure control with gastrointestinal side effects optimally controlled. As long as health care professionals carefully manage MCTKD, many more patients with epilepsy who are not appropriate for CKD or modified Atkins diet or low glycemic index treatment will benefit from this treatment. A comparison between the MCTKD and other KDs is also discussed.

    BACKGROUND Carbohydrate tumor-associated antigen (CA 19-9) has been shown to be upregulated in other malignant tumors including gastric, ovarian, hepatocellular, and colorectal carcinoma as well as benign diseases of the biliary track such as pancreatitis, cholangitis, and choledocholithiasis. According to the available literature, in several cases of benign hydronephrosis and in a few cases of benign renal diseases, elevated CA 19-9 has been noted. CASE REPORT A 58-year-old Caucasian male patient was admitted in our clinic with complaints about blunt abdominal pain in the past two-month period localized in the right lumbar region and irradiating into the right inguinal area, constipation, abdominal bloating, and intermittent hematuria. The concentration of serum CA 19-9 was 3500 U/mL. Urine cytology provided no signs of abnormality. Intravenous urography visualized right-sided pyelon and ureter duplex with the defect in contrast shade of the pyelon, caused by a stag horn calculus. Contrast added computerized axial tomography of the abdomen and pelvis visualized the pyelon casted concretion spreading throughout the right pyelon, with ureterohydronephrosis with the distal block for passage of the contrast to the distal part of the ureter. CONCLUSIONS There is no doubt that CA 19-9 level is occasionally elevated in patients with obstructive urolithiasis as it was in our case. In the routine medical praxis, urolithiasis should not be neglected in the differential diagnosis of elevated concentrations of CA 19-9 marker. PMID:27287959

    Full Text Available Objective. The correlation between meridians and organs (Zang-fu is an important aspect of meridian theory. The objective of this paper is to investigate the pathological changes in the organs resulting from blocking low hydraulic resistance channel (LHRC along the stomach meridian by injecting gel in pigs so as to offer some insight into the correlation between meridians and internal organs. Methods. Four white piglets and twelve black minipigs were divided into four batches and were observed in different periods. Each batch included two pairs of pigs and each pair matched two pigs with similar conditions among which gel was injected into 6~8 low hydraulic resistance points along the the stomach meridian in the experimental pig and the same amount of saline was injected into the same points in the control pig. The state of stomach and intestine was observed 6~10 weeks after the blocking model was developed. Results. The results showed that there were bloated stomach or/and intestine in all the experimental pigs while there were normal states in seven control pigs except one dead during the experiment. Conclusion. The findings confirmed that the blockage of LHRC along the stomach meridian can influence the state of stomach and intestine, leading to a distension on stomach or/and intestine.

    2013-01-01

    We report the discovery of the transiting exoplanets WASP-69b, WASP-70Ab and WASP-84b, each of which orbits a bright star (V~10). WASP-69b is a bloated Saturn-mass planet (0.26 M$_{\\rm Jup}$, 1.06 R$_{\\rm Jup}$) in a 3.868-d period around an active mid-K dwarf. We estimate a stellar age of 1 Gyr from both gyrochronological and age-activity relations, though an alternative gyrochronological relation suggests an age of 3 Gyr. ROSAT detected X-rays at a distance of 60$\\pm$27 arcsec from WASP-69. If the star is the source then the planet could be undergoing mass-loss at a rate of ~10$^{12}$ g s$^{-1}$. This is 1-2 orders of magnitude higher than the evaporation rate estimated for HD 209458b and HD 189733b, both of which have exhibited anomalously-large Lyman-{\\alpha} absorption during transit. WASP-70Ab is a sub-Jupiter-mass planet (0.59 M$_{\\rm Jup}$, 1.16R$_{\\rm Jup}$) in a 3.713-d orbit around the primary of a spatially-resolved G4+K3 binary, with a separation of 3.3 arcsec ($\\geq$800 AU). We exploit the binar...

    We report the discovery of two new transiting planets from the WASP survey. WASP-42 b is a 0.500 +- 0.035 M_J planet orbiting a K1 star at a separation of 0.0548 +- 0.0017 AU with a period of 4.9816872 +- 0.0000073 days. The radius of WASP-42 is 1.080 +- 0.057 R_J while its equilibrium temperature is T_eq = 995 +- 34 K. We detect some evidence of a small but non-zero eccentricity of e = 0.060 +- 0.013. WASP-49 b is a 0.378 +- 0.027 M_J planet around an old G6 star. It has a period of 2.7817387 +- 5.6 x 10-6 days and a separation of 0.0379 +- 0.0011 AU. This planet is slightly bloated, having a radius of 1.115 +- 0.056 R_J and an equilibrium temperature of T_eq = 1369 +- 42 K. Both planets have been followed up intensively in photometry, in total we have obtained 5 full and one partial transit light curves of WASP-42 and 4 full and one partial light curves of WASP-49 using the Euler-Swiss, TRAPPIST and Faulkes South telescopes.

    2012-01-01

    We present three newly discovered sub-Jupiter mass planets from the SuperWASP survey: WASP-54b is a heavily bloated planet of mass 0.636$^{+0.025}_{-0.024}$ \\mj and radius 1.653$^{+0.090}_{-0.083}$ \\rj. It orbits a F9 star, evolving off the main sequence, every 3.69 days. Our MCMC fit of the system yields a slightly eccentric orbit ($e=0.067^{+0.033}_{-0.025}$) for WASP-54b. We investigated further the veracity of our detection of the eccentric orbit for WASP-54b, and we find that it could be real. However, given the brightness of WASP-54 V=10.42 magnitudes, we encourage observations of a secondary eclipse to draw robust conclusions on both the orbital eccentricity and the thermal structure of the planet. WASP-56b and WASP-57b have masses of 0.571$^{+0.034}_{-0.035}$ \\mj and $0.672^{+0.049}_{-0.046}$ \\mj, respectively; and radii of $1.092^{+0.035}_{-0.033}$ \\rj for WASP-56b and $0.916^{+0.017}_{-0.014}$ \\rj for WASP-57b. They orbit main sequence stars of spectral type G6 every 4.67 and 2.84 days, respectively...

    We report the discovery of three new transiting hot Jupiters by WASP-South together with the TRAPPIST photometer and the Euler/CORALIE spectrograph. WASP-74b orbits a star of V = 9.7, making it one of the brighter systems accessible to Southern telescopes. It is a 0.95 M_Jup planet with a moderately bloated radius of 1.5 R_Jup in a 2-d orbit around a slightly evolved F9 star. WASP-83b is a Saturn-mass planet at 0.3 M_Jup with a radius of 1.0 R_Jup. It is in a 5-d orbit around a fainter (V = 12.9) G8 star. WASP-89b is a 6 M_Jup planet in a 3-d orbit with an eccentricity of e = 0.2. It is thus similar to massive, eccentric planets such as XO-3b and HAT-P-2b, except that those planets orbit F stars whereas WASP-89 is a K star. The V = 13.1 host star is magnetically active, showing a rotation period of 20.2 d, while star spots are visible in the transits. There are indications that the planet's orbit is aligned with the stellar spin. WASP-89 is a good target for an extensive study of transits of star spots.

  5. Role of cholecystokinin and central serotonergic receptors in functional dyspepsia

    Symptoms of functional dyspepsia are characterized by upper abdominal discomfort or pain, early satiety, postprandial fullness, bloating, nausea and vomiting. It is a chronic disorder, with symptoms more than 3 mo per year, and no evidence of organic diseases. Dysfunctional motility, altered visceral sensation, and psychosocial factors have all been identified as major pathophysiological mechanisms. It is believed that these pathophysiological mechanisms interact to produce the observed symptoms.Dyspepsia has been categorized into three subgroups based on dominant symptoms. Dysmotility-like dyspepsia describes a subgroup of patients whose symptom complex is usually related to a gastric sensorimotor dysfunction. The brain-gut peptide cholecystokinin (CCK)and serotonin (5-HT) share certain physiological effects.Both have been shown to decrease gastric emptying and affect satiety. Furthermore the CCK induced anorexia depended on serotonergic functions probably acting via central pathways. We believe that abnormalities of central serotonergic receptors functioning together with a hyper responsiveness to CCK or their interactions may be responsible for the genesis of symptoms in functional dyspepsia (FD).

  6. Curcumin ameliorates gastrointestinal dysfunction and oxidative damage in diabetic rats

    Full Text Available Diabetes is known to be associated with gastrointestinal complications characterized by nausea, vomiting, early satiety, bloating, and abdominal discomfort or pain commonly occurring in the advanced stages of the disease. Curcumin is the lipid-soluble antioxidant obtained from the rhizomes of Curcuma longa Linn, also known as turmeric. Curcumin targets multiple chemotherapeutic and oxidative stress pathways and has demonstrated safety and tolerability in humans, supporting its potential as a therapeutic agent; however, literature lacks conclusive evidence supporting its use as a therapeutic agent for the treatment of diabetes induced gastrointestinal complications. Hence, Curcumin was given in different doses to SD rats after 4 weeks of diabetic GI complication induction. At the end of 4 weeks, significant GI dysfunction characterized by weight loss, delayed gastric emptying and intestinal transit associated with reduction in antioxidant enzyme levels and increased lipid peroxidation was observed.  Upon treatment with Curcumin for further 4 weeks, reversal of GI dysfunction evidenced by restoration of body weight, GI emptying, intestinal transit, and restoration of antioxidant enzyme level and lipid peroxidation proves the beneficial role of Curcumin in diabetes induced GI complications due to its antioxidant potential.

    The transiting extrasolar planet WASP-12 b was found to be one of the most intensely irradiated exoplanets. It is unexpectedly bloated and is losing mass that may accrete into the host star. Our aim was to refine the parameters of this intriguing system and search for signs of transit timing variations. We gathered high-precision light curves for two transits of WASP-12 b. Assuming various limb-darkening laws, we generated best-fitting models and redetermined parameters of the system. Error estimates were derived by the prayer bead method and Monte Carlo simulations. System parameters obtained by us are found to agree with previous studies within one sigma. Use of the non-linear limb-darkening laws results in the best-fitting models. With two new mid-transit times, the ephemeris was refined to BJD(TDB)=(2454508.97682 +/- 0.00020) + (1.09142245 +/- 0.00000033) E. Interestingly, indications of transit timing variation are detected at the level of 3.4 sigma. This signal can be induced by an additional planet in ...

    Extrinsic sensory neurons play a key role in the function of the gastrointestinal tract. They are responsible for the sensations that arise in the gut and can initiate automatic reflexes. In some cases, disordered sensation is clinically problematic-pain, bloating, excessive urgency and nausea are well-known examples. Major advances have been made in understanding the function of somatic sensory neurons in the last 50 years. However, the sensory neurons that mediate sensations from the viscera remain less well understood. This is partly because viscera receive a dense autonomic innervation that can be difficult to separate from extrinsic sensory neurons. A key requirement to understand the genesis of sensation is to distinguish the different classes of sensory neurons and the types of stimuli which they encode. The aim of this short paper is to summarise what was known about these matters 30 years ago and highlight some of the major advances in the understanding of the types of extrinsic sensory neurons to the gut. Necessarily, the choice of papers is somewhat idiosyncratic, but they illustrate the range of advances that have been made in distinguishing the different classes of gastrointestinal afferent nerves.

    AIM: To prospectively investigate the effectiveness and patient's tolerance of two low-cost bowel cleansing preparation protocols based on magnesium citrate only or the combination of magnesium citrate and senna. METHODS: A total of 342 patients who were referred for colonoscopy underwent a colon cleansing protocol with magnesium citrate alone ( n = 160) or magnesium citrate and senna granules ( n = 182). The colonoscopist rated the overall efficacy of colon cleansing using an established score on a 4-point scale. Patients were questioned before undergoing colonoscopy for side effects and symptoms during bowel preparation. RESULTS: The percentage of procedures rescheduled because of insufficient colon cleansing was 7% in the magnesium citrate group and 4% in the magnesium citrate/senna group ( P = 0.44). Adequate visualization of the colonic mucosa was rated superior under the citramag/senna regimen ( P = 0.004). Both regimens were well tolerated, and did not significantly differ in the occurrence of nausea, bloating or headache. However, abdominal cramps were observed more often under the senna protocol (29.2%) compared to the magnesium citrate only protocol (9.9%, P < 0.0003). CONCLUSION: The addition of senna to the bowel preparation protocol with magnesium citrate significantly improves the cleansing outcome.

  10. Eosinophilic enteritis demonstrated on 99mTc HMPAO white cell imaging

    International Nuclear Information System (INIS)

    Full text: A 46-year-old male with a 10-year history of biopsy proven Eosinophilic Gastroenteritis presented with a refractory exacerbation consisting of symptoms of severe lower abdominal pain, bloating and intermittent diarrhoea. Previous investigations during attacks had shown a blood eosinophilia, and earlier serial barium studies had demonstrated small bowel thickening and narrowing. The condition had previously responded to oral steroids. A 99mTc HMPAO labelled white cell scan was performed to assess for an inflammatory focus. The standard cell labelling technique was performed using 55ml of patient's whole blood, and labelled white cells reinjected approximately 2.5 hours later. Imaging was performed using a Siemens Ecam dual head gamma camera. Anterior, Posterior, right and left lateral images were acquired at 90 minutes and 3 hours post injection. All images were acquired using a 128W matrix for 5 minutes, with a 140kev peak and 20% window. Images demonstrated diffuse increased activity in the ileum on both the 90-minute and 3 hours images consistent with inflammatory changes. A recent barium swallow and follow through study was normal. The patient was successfully treated with a course of high dose intravenous steroids. Eosinophilic Enteritis is an extremely rare and poorly understood condition of unknown aetiology. This case study demonstrates that Nuclear Medicine white cell imaging may play a role in the diagnosis and management of patients diagnosed with this condition.

    Chronic intestinal pseudo-obstruction (CIP) is an infre-quent complication of an active systemic lupus erythema-tosus (SLE). We illustrate a case of SLE inactive-related CIP. A 51-year old female with inactive SLE (ECLAM score 2) was hospitalized with postprandial fullness, vomiting, abdominal bloating and abdominal pain. She had had no bowel movements for five days. Plain abdominal X-ray revealed multiple fluid levels and dilated small and large bowel loops with air-fluid levels. Intestinal contrast radiology detected dilated loops. CIP was diagnosed. The patient was treated with prokinetics, octreotide, claritromycin, rifaximin, azathioprine and tegaserod without any clinical improvement. Then methylprednisolone (500 mg iv daily) was started. After the first administration, the patient showed peristaltic movements. A bowel movement was reported after the second administration. A plain abdominal X-ray revealed no air-fluid levels. Steroid therapy was slowly reduced with complete resolution of the symptoms. The patient is still in a good clinical condition. SLE-related CIP is generally reported as a complication of an active disease. In our case, CIP was the only clinical demonstration of the SLE.

    2012-01-01

    Full Text Available “Mucositis” is the clinical term used to describe ulceration and damage of the mucous membranes of the entire gastrointestinal tract (GIT following cytotoxic cancer chemotherapy and radiation therapy common symptoms include abdominal pain, bloating, diarrhoea, vomiting, and constipation resulting in both a significant clinical and financial burden. Chemotherapeutic drugs cause upregulation of stress response genes including NFκB, that in turn upregulate the production of proinflammatory cytokines such as interleukin-1β (IL-1β, Interleukin-6 (IL-6, and tumour necrosis factor-α (TNF-α. These proinflammatory cytokines are responsible for initiating inflammation in response to tissue injury. Anti-inflammatory cytokines and specific cytokine inhibitors are also released to limit the sustained or excessive inflammatory reactions. In the past decade, intensive research has determined the role of proinflammatory cytokines in development of mucositis. However, a large gap remains in the knowledge of the role of anti-inflammatory cytokines in the setting of chemotherapy-induced mucositis. This critical paper will highlight current literature available relating to what is known regarding the development of mucositis, including the molecular mechanisms involved in inducing inflammation particularly with respect to the role of proinflammatory cytokines, as well as provide a detailed discussion of why it is essential to consider extensive research in the role of anti-inflammatory cytokines in chemotherapy-induced mucositis so that effective targeted treatment strategies can be developed.

    Full Text Available Background. Gastroparesis is a heterogeneous disorder most often idiopathic, diabetic, or postsurgical in nature. The demographic and clinical predictors of gastroparesis in Israeli patients are poorly defined. Methods. During the study period we identified all adult patients who were referred to gastric emptying scintigraphy (GES for the evaluation of dyspeptic symptoms. Of those, 193 patients who were referred to GES from our institution were retrospectively identified (76 (39% males, mean age 60.2±15.6 years. Subjects were grouped according to gastric half-emptying times (gastric T1/2. Demographic and clinical data were extracted from electronic medical records or by a phone interview. Key Results. Gastric emptying half-times were normal (gastric T1/2 0–99 min in 101 patients, abnormal (gastric T1/2 100–299 min in 67 patients, and grossly abnormal (gastric T1/2≥300 min in 25 patients. Vomiting and dysphagia, but neither early satiety nor bloating, correlated with delayed gastric emptying. Diabetes was associated with grossly abnormal gastric T1/2. Idiopathic gastroparesis was associated with a younger age at GES. No correlation was observed between gastric T1/2 values and gender, smoking, H. pylori infection, HBA1C, or microvascular complication of diabetes. Conclusions Inferences. Vomiting and dysphagia are predictive of delayed gastric emptying in both diabetic and nondiabetic subjects. Diabetes is associated with more severe gastroparesis.

  14. Dietary Carbohydrates and Childhood Functional Abdominal Pain.

    Chumpitazi, Bruno P; Shulman, Robert J

    2016-01-01

    Childhood functional gastrointestinal disorders (FGIDs) affect a large number of children throughout the world. Carbohydrates (which provide the majority of calories consumed in the Western diet) have been implicated both as culprits for the etiology of symptoms and as potential therapeutic agents (e.g., fiber) in childhood FGIDs. In this review, we detail how carbohydrate malabsorption may cause gastrointestinal symptoms (e.g., bloating) via the physiologic effects of both increased osmotic activity and increased gas production from bacterial fermentation. Several factors may play a role, including: (1) the amount of carbohydrate ingested; (2) whether ingestion is accompanied by a meal or other food; (3) the rate of gastric emptying (how quickly the meal enters the small intestine); (4) small intestinal transit time (the time it takes for a meal to enter the large intestine after first entering the small intestine); (5) whether the meal contains bacteria with enzymes capable of breaking down the carbohydrate; (6) colonic bacterial adaptation to one's diet, and (7) host factors such as the presence or absence of visceral hypersensitivity. By detailing controlled and uncontrolled trials, we describe how there is a general lack of strong evidence supporting restriction of individual carbohydrates (e.g., lactose, fructose) for childhood FGIDs. We review emerging evidence suggesting that a more comprehensive restriction of fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) may be effective. Finally, we review how soluble fiber (a complex carbohydrate) supplementation via randomized controlled intervention trials in childhood functional gastrointestinal disorders has demonstrated efficacy.

    2012-01-01

    Full Text Available Abdominal pain, bloating, early satiety, and changes in bowel habits are common presenting symptoms in individuals with functional GI disorders. Emerging data suggests that these symptoms may be associated with mast cell excess and/or mast cell instability in the GI tract. The aim of this retrospective study was to evaluate the contribution of mast cells to the aforementioned symptoms in individuals with a history of atopic disease. A retrospective chart review of individuals seen in a university GI practice was conducted and twenty-four subjects were identified. The majority had abdominal pain, early satiety, and nocturnal awakening. 66.7% and 37.5% had a history of environmental and/or food allergy. Solid gastric emptying was increased as were the mean number of mast cells reported on biopsies from the stomach, small bowel, and colon (>37/hpf by CD117 staining. Mean whole blood histamine levels were uniformly elevated. This study suggests that in individuals with these characteristics, consideration should be given to staining their gastrointestinal biopsies for mast cells as this may provide them with relatively non-toxic but highly targeted treatment options. Allergic gastroenteritis and colitis may represent a third type of GI mast cell disorder along with mast cell activation syndrome and mastocytic enterocolitis.

    Full Text Available Objective: Gastrointestinal motility and functional motility disorders causing either delayed or accelerated gastric emptying (GE may result in similar symptoms including nausea, vomiting, early satiety, fullness, bloating, and abdominal discomfort or pain. Hence, it is important to evaluate patients for both rapid and delayed GE in the same test. The gold standard technique to measure GE is scintigraphy by radiolabeled test meals. The aim of this study was to test alternative Tc-99m agents to label eggs as the solid meal and compare to Tc-99m sulfur colloid (SC for gastric emptying studies. Methods: In search of alternative agents for gastric emptying studies, we mixed and fried eggs with four different particulate compounds (Tc-99m labeled SC, tin colloid, nanocolloid and MAA, as well as with free pertechnetate and Tc-99m DTPA. We then measured the stability of these compounds in simulated gastric juice. Results: Our experiments demonstrated that in addition to Tc-99m sulfur colloid;Tc-99m MAA, Tc-99m nanocolloid and Tc-99m tin colloid also appear to make stable complexes with eggs in acidic environment. Conclusion: Therefore, these agents may be used for gastric emptying studies which could be more practical in routine conditions.

    Diabetes is associated with several changes in gastrointestinal (GI) motility and associated symptoms such as nausea, bloating, abdominal pain, diarrhoea and constipation. The pathogenesis of altered GI functions in diabetes is multifactorial and the role of the enteric nervous system (ENS) in this respect has gained significant importance. In this review, we summarize the research carried out on diabetes-related changes in the ENS. Changes in the inhibitory and excitatory enteric neurons are described highlighting the role of loss of inhibitory neurons in early diabetic enteric neuropathy. The functional consequences of these neuronal changes result in altered gastric emptying, diarrhoea or constipation. Diabetes can also affect GI motility through changes in intestinal smooth muscle or alterations in extrinsic neuronal control. Hyperglycaemia and oxidative stress play an important role in the pathophysiology of these ENS changes. Antioxidants to prevent or treat diabetic GI motility problems have therapeutic potential. Recent research on the nerve-immune interactions demonstrates inflammation-associated neurodegeneration which can lead to motility related problems in diabetes. PMID:17971027

    Wireless full-duplex radios can simultaneously transmit and receive using the same frequency. In theory, this can double the throughput. In fact, there is only little work addressing aspects other than throughput gains in full-duplex systems. Over-buffering in today\\'s networks or the so-called “bufferbloat” phenomenon creates excessive end-to-end delays resulting in network performance degradation. Our analysis shows that full-duplex systems may suffer from high latency caused by bloated buffers. In this paper, we address the problem of buffer management in full-duplex networks by using Wireless Queue Management (WQM), which is an active queue management technique for wireless networks. Our solution is based on Relay Full-Duplex MAC (RFD-MAC), an asynchronous media access control protocol designed for relay full-duplexing. We compare the performance of WQM in full-duplex environment to Drop Tail mechanism over various scenarios. Our solution reduces the end-to-end delay by two orders of magnitude while achieving similar throughput in most of the cases.

    Marsdenia megalantha is a rupicolous shrub with succulent roots from the semiarid region of Brazil that is known to cause fatal poisoning in livestock. We reported spontaneous cases of poisoning by M. megalantha roots in bovine, caprine, ovine, and equine species. The clinical and pathological findings of experimental administration of M. megalantha to sheep, goats, a calf and a pig are reported. Three goats, two sheep and a calf were dosed once orally with freshly chopped roots at dose of 25 g wet plant/kg bw; another sheep and a pig were dosed with 10 g wet plant/kg bw. Poisoning occurred in all of the animals except the three goats. Clinical signs of poisoning included tachycardia, opisthotonus, ruminal bloat, dyspnea, nystagmus, mydriasis, ataxia, and recumbence with paddling movements. Pathological evaluation showed segmental laminar neuronal necrosis and spongiosis in the telencephalic cortex and degeneration of Purkinje cells. The picrate paper procedure detected no cyanide in the plant roots, but the reaction used for nitrate detection gave a strongly positive response. In conclusion, M. megalantha is a poisonous plant that produces acute poisoning characterized mainly by nervous disturbances. Livestock producers should offer alternative food during the dry and early rainy seasons to avoid the poisoning by this plant. PMID:23266310

    This study determined the prevalence of diseases and pathogens associated with mortality or severe morbidity in 72 Ontario beef feedlots in calves that died or were euthanized within 60 days after arrival. Routine pathologic and microbiologic investigations, as well as immunohistochemical staining for detection of bovine viral diarrhea virus (BVDV) antigen, were performed on 99 calves that died or were euthanized within 60 days after arrival. Major disease conditions identified included fibrinosuppurative bronchopneumonia (49%), caseonecrotic bronchopneumonia or arthritis (or both) caused by Mycoplasma bovis (36%), viral respiratory disease (19%), BVDV-related diseases (21%), Histophilus somni myocarditis (8%), ruminal bloat (2%), and miscellaneous diseases (8%). Viral infections identified were BVDV (35%), bovine respiratory syncytial virus (9%), bovine herpesvirus-1 (6%), parainfluenza-3 virus (3%), and bovine coronavirus (2%). Bacteria isolated from the lungs included M. bovis (82%), Mycoplasma arginini (72%), Ureaplasma diversum (25%), Mannheimia haemolytica (27%), Pasteurella multocida (19%), H. somni (14%), and Arcanobacterium pyogenes (19%). Pneumonia was the most frequent cause of mortality of beef calves during the first 2 months after arrival in feedlots, representing 69% of total deaths. The prevalence of caseonecrotic bronchopneumonia caused by M. bovis was similar to that of fibrinosuppurative bronchopneumonia, and together, these diseases were the most common causes of pneumonia and death. M. bovis pneumonia and polyarthritis has emerged as an important cause of mortality in Ontario beef feedlots. PMID:16566254

    Irritable bowel syndrome (IBS) affects 10-15% of the western population. Drug therapy for this entity has shown limited efficacy. The low Fermentable Oligo-, Di-, Monosaccharides And Polyols (FODMAP) diet has recently emerged as an effective intervention for reducing gastrointestinal symptoms in IBS. Currently, several mechanistic studies have proven the rational basis of carbohydrate restriction. In addition, high-quality evidence (prospective studies and randomized controlled trials) from a variety of countries supports the high effectiveness of a low-FODMAP diet for IBS symptoms (70%), especially abdominal bloating, pain, and diarrhea. Importantly, this diet seems to be superior to a gluten-free diet for patients with non-celiac gluten sensitivity. The most controversial features of the low FODMAP diet are its short- and long-term limitations (a high level of restriction, the need for monitoring by an expert dietitian, potential nutritional deficiencies, significant gut microbiota reduction, lack of predictors of response), as well as the potential lack of advantage over alternative dietary, pharmacological and psychological interventions for IBS. Although liberalization of carbohydrate intake is recommended in the long-term, the reintroduction process remains to be clarified as, theoretically, global carbohydrate restriction is deemed to be necessary to avoid additive effects.

    We describe seven new exoplanets transiting stars of V = 10.1 to 12.4. WASP-130b is a "warm Jupiter" having an orbital period of 11.6 d, the longest yet found by WASP. It transits a V = 11.1, G6 star with [Fe/H] = +0.26. Warm Jupiters tend to have smaller radii than hot Jupiters, and WASP-130b is in line with this trend (1.23 Mjup; 0.89 Rjup). WASP-131b is a bloated Saturn-mass planet (0.27 Mjup; 1.22 Rjup). Its large scale height coupled with the V = 10.1 brightness of its host star make the planet a good target for atmospheric characterisation. WASP-132b is among the least irradiated and coolest of WASP planets, being in a 7.1-d orbit around a K4 star. It has a low mass and a modest radius (0.41 Mjup; 0.87 Rjup). The V = 12.4, [Fe/H] = +0.22 star shows a possible rotational modulation at 33 d. WASP-139b is the lowest-mass planet yet found by WASP, at 0.12 Mjup and 0.80 Rjup. It is a "super-Neptune" akin to HATS-7b and HATS-8b. It orbits a V = 12.4, [Fe/H] = +0.20, K0 star. The star appears to be anomalously...

    Full Text Available No abstract available. Article truncated after 150 words. A 52-year-old Hispanic woman with a past medical history significant for Type 1 Diabetes Mellitus, hypertension, and rheumatoid arthritis presented with left upper quadrant pain for one day. Her review of systems was positive for bloating, severe epigastric and left upper quadrant tenderness that radiated to the back and left shoulder, nausea with non-bilious emesis, and diarrhea for one day prior to admission. Physical exam only revealed epigastric and left upper quadrant tenderness to light palpation without rebound or guarding.

    Ascariasis is the most common helminthic infection in developing countries. It may cause chronic abdominal pain, tenderness and bloating. Our aim is to report a case of acute episodic abdominal pain and pancreatitis associated with ascariasis. We report a 59-year-old female patient who was admitted for acute abdominal pain, having had several previous similar events before one of them was diagnosed as acute idiopathic pancreatitis. On admission, her physical exam was normal. Laboratory results showed hemoglobin 12.2 g/dL, white blood cell count 11 900 cells/mm(3), eosinophils 420 cells/mm(3), serum amylase 84 IU/mL, lipase 22 IU/mL and normal liver function tests. Abdominal ultrasound and a plain abdominal X-ray were also normal. An upper endoscopy showed round white worms in the duodenum and the stomach, some of them with bile in their intestines. The intestinal parasites were diagnosed as Ascaris lumbricoides, and the patient was started on albendazole, with full recovery within a week. We believe that ascariasis should be considered in patients with recurrent abdominal pain and idiopathic pancreatitis. PMID:20447214

    Methicillin-resistant Staphylococcus aureus (MRSA) is a pathogen of major public health importance. Colonisation precedes infection; thus reducing MRSA carriage may be of benefit for reducing infection. Probiotics represent a novel approach to reducing MRSA carriage. We undertook a pilot feasibility randomised controlled trial of the tolerability and acceptability of probiotics for reducing nasal and intestinal carriage of MRSA. In addition, subjects were screened for vancomycin-resistant enterocococci (VRE). Subjects with a history of MRSA were recruited from a large, academic medical center and randomised to take either a placebo or probiotic (Lactobacillus rhamnosus HN001). Subjects returned to the clinic after four weeks for further testing to determine adherence to the probiotic regimen and colonisation of MRSA. 48 subjects were enrolled and randomised. Nearly 25% were transplant recipients and 30% had diabetes. The probiotic was well tolerated in the study population though minor side effects, such as nausea and bloating, were observed. A majority of the subjects randomised to HN001 had good adherence to the regimen. At the four week time point among subjects randomised to the probiotic, MRSA was detected in 67 and 50% of subjects colonised in the nares and the gastrointestinal tract, respectively. Three subjects who initially tested positive for VRE were negative after four weeks of probiotic exposure. Probiotics were well tolerated in our study population of largely immunocompromised subjects with multiple comorbidities. Adherence to the intervention was good. Probiotics should be studied further for their potential to reduce colonisation by multidrug resistant bacteria. PMID:25213147

    This experiment was designed to prevent rumen bloat, easily caused by feeding ruminants with high protein feed, from occurring effectively. Adding different ratio of the white clover to lotus pedunculatus (2:1, 2:2, 2:3 and 2:4) to rumen liquid, and then measured the weight of dry matter, soluble protein, foam production (cc), gas production and the changes of condensed tannins after cultured for 24 h. The results indicated that soluble condensed tannin and fiber bound condensed tannin decreased in different treatments, in addition, soluble condensed tannin reduced while protein bound condensed tannin increased reversely. When the ratio was 2:3, foam production (cc) decreased significantly compared with treatment with white clover alone, along with the increasement of lotus pedunculatus, the production of CO2 was decreased. In conclusion, the soluble condensed tannin in lotus pedunculatus was able to bind soluble protein and then converted into protein bound condensed tannin. This course can prevent the produce of foam and occurrence of rumen bloat as well as protect the undegradation protein. In order to get the significant effect, the lowest ratio of tannin containing forages in high protein forages was 2:2.%蛋白含量高的豆科牧草及高蛋白饲料饲喂反刍动物时易发生臌胀病,为有效防止臌胀病的发生,试验用4种不同比例的白三叶和长柄百脉根(分别为2∶1、2∶2、2∶3、2∶4)添加延边黄牛瘤胃液培养24h后测量干物质重、可溶性蛋白质、泡沫生成量(cc)、气体生成量及缩合单宁变化来比较差异.培养24h后,各处理中水溶性缩合单宁和纤维结合单宁减少,而蛋白结合单宁增加.白三叶与长柄百脉根比例为2∶3时比单独的白三叶处理时泡沫产生量显著减少;随着长柄百脉根的添加,CO2产量显著减少.这些结果表明,长柄百脉根内水溶性缩合单宁与可溶性蛋白结合转变为蛋白结合单宁,从而减少瘤胃内泡沫

    Full Text Available The domestic pig (Sus scrofa was used as a model to study arthropod succession on carcasses under tree shade and out of shade in southern Nigeria. Carcass decomposition took longer periods under tree shade than in exposed sites, at 24.5 and 16.5 days, respectively. Four decomposition stages - fresh, bloated, decay, and dry - were observed. No significant variabilities were recorded in the types and patterns of infestation of the carcasses by arthropods in both locations. Four classes of arthropods - Insecta, Arachnida, Diplopoda and Crustacea - were recorded. The class Insecta dominated the total arthropods collected with 24 families, and formed 94% of the catches. The other three classes each had one family represented, and contributed only 2% of the total catches. The calliphorids, a phorid, and sarcophagids arrived and bred on the carcasses only a few hours after death of the pigs. Families of coleopterans came during the bloated stage, and fed on the immature dipterous maggots and carrion materials. The ants (Hymenoptera came in large numbers to eat the carcasses, and also preyed on all other fauna of the food resource. A muscid and a stratiomyiid, bred on the carcass as to the decay stage. Other insects and arthropods arrived mostly during the decay stage to feed on the carcasses. Species richness on the carcasses peaked during the decay stage.O porco branco (Sus scrofa foi usado como modelo para o estudo da sucessão de Artrópodes em cadáveres em zonas sombreadas e não sombreadas por árvores no sul da Nigéria.

    2016-07-01

    Consumer confidence in the food industry is severely affected by large-scale spoilage incidents. However, relatively little research exists on spoilage potential of members of the fungal subphylum Mucormycotina (e.g. Mucor), which includes dimorphic spoilage organisms that can switch between a yeast-like and hyphal phase depending on environmental conditions. The presence of Mucor circinelloides in yogurt may not cause spoilage, but growth and subsequent changes in quality (e.g. container bloating) can cause spoilage if not controlled. The purpose of this study was to evaluate the effects on M. circinelloides of pasteurization regimen, natamycin concentrations, and storage temperature in yogurt production, as measured by fungal proliferation and carbon dioxide production. A strain of M. circinelloides isolated from commercially spoiled yogurt showed greater yogurt-spoilage potential than clinical isolates and other industrial strains. D-values and z-values were determined for the spoilage isolate in milk as an evaluation of the fungus' ability to survive pasteurization. Natamycin was added to yogurt at 0, 5, 10, 15, and 20ppm (μg/ml) to determine its ability to inhibit M. circinelloides over the course of month-long challenge studies at 4°C, 15°C, and 25°C. Survivors were recovered on acidified PDA and carbon dioxide levels were recorded. The D-values at 54°C, 56°C, and 58°C for hyphae/sporangiospores were (in min) 38.31±0.02, 10.17±0.28, and 1.94±0.53, respectively, which yielded a z-value of 3.09°C. The D-values at 51°C, 53°C, and 55°C for yeast-like cells were (in min) 14.25±0.12, 6.87±1.19, and 2.44±0.35, respectively, which yielded a z-value of 0.34°C. These results indicated that M. circinelloides would not survive fluid milk pasteurization if contamination occurred prior to thermal treatment. CO2 production was only observed when M. circinelloides was incubated under low-oxygen conditions, and occurred only at temperatures above 4

    2016-05-01

    Irritable bowel syndrome is a functional bowel disorder with gastrointestinal symptoms (e.g. abdominal pain, straining, urgency, incomplete evacuation, nausea, and bloating) that occur alongside bowel function alterations (i.e. constipation, diarrhea, or both). Patients with irritable bowel syndrome may also experience comorbid anxiety and depression. Irritable bowel syndrome is common, with a prevalence estimated between 3% and 28%, affecting patient health and quality of life. Patients with moderate or severe irritable bowel syndrome generally seek medical care, whereas those with milder symptoms may choose self-management. Most patients with irritable bowel syndrome receive outpatient care, but irritable bowel syndrome-related hospitalizations do occur. The pathophysiology of irritable bowel syndrome is multifactorial (i.e. genetics, immune components, changes in the gut microbiota, disturbances in physiologic stress response systems, and psychosocial factors). Management of irritable bowel syndrome can include lifestyle changes, dietary interventions, counseling, psychologic medication, and agents that affect gastrointestinal motility. A number of therapies have emerged in recent years with clinical trial data demonstrating efficacy and safety for patients with irritable bowel syndrome, including agents that target gastrointestinal motility (i.e. linaclotide), gastrointestinal opioid receptors (i.e. asimadoline, eluxadoline), and gut microbiota (i.e. rifaximin). Linaclotide has been shown to significantly improve stool frequency and abdominal pain compared with placebo in constipation-predominant irritable bowel syndrome (number needed to treat, 5.1). Asimadoline shows efficacy in patients with moderate-to-severe irritable bowel syndrome-related pain. Rifaximin provided adequate relief of global irritable bowel syndrome symptoms versus placebo for a significantly greater percentage of patients with diarrhea-predominant irritable bowel syndrome (p < 0

    Feeding a high concentration of condensed tannins will reduce protein degradation and voluntary feed intake, damage abomasum or intestine. However, appropriate concentration of condensed tannins have beneficial effects on prevention of bloat and pulmonary edema, reducing parasitic disease and pastoral flavour in meat products, improving animal performance. Condensed tannins are clearly a "double edged sword" for feeding value. Successful management of condensed tannins depends on a combination of chemical analysis and animal experimentation. This paper is a review on nutrition and anti-nutrition of condensed tannins for ruminants, the factors affecting content of condensed tannins in forage, and the methods of controling concentration of condensed tannins. Research on successful management of condensed tannins will offer a real benefit for farmers.%饲料中高浓度的缩合单宁会降低动物对营养物质的消化利用率,影响自愿采食量,甚至损伤肠胃.适宜含量的缩合单宁,又能阻止臌胀病、肺水肿的发生,降低寄生虫病害的影响,改善肉质品味,提高动物的生产性能.论文概述了缩合单宁的营养作用、抗营养作用,影响饲草缩合单宁含量的因素,以及控制缩合单宁含量的方法,以便在实践中合理应用缩合单宁.

    In this paper a review of the researches on the role of Escherichia coli strain Nissle 1917 (EcN) in gastrointestinal diseases was presented. EcN is a non-pathogenic strain of the Enterobacteriaceae family, which has probiotic properties. In a number of studies conducted among humans and  experimental animals the application of EcN in treatment of gastrointestinal diseases was observed. Most studies about EcN has been devoted to this organism efficacy in ulcerative colitis treatment. Comparable results were obtained, by citied authors, in the treatment (sustaining remission) of EcN and mesalazine in ulcerative colitis. Moreover, this probiotic therapy, compared to placebo, contributes to obtaining a faster remission and improvement of intestinal histopathology. The use of EcN in Crohn's disease has not been the subject of as many studies as in the case of ulcerative colitis. Assessing the importance of EcN in treatment of other gastrointestinal disorders, authors of the studies observed, that in patients with irritable bowel syndrome, who receiving this probiotic there was a pain, nausea and bloating reduction. In studies conducted among children a positive impact of EcN in prevention and treatment of diarrhea was demonstrated. Similar results were obtained in studies conducted in experimental animals. Based on the presented review it can be concluded that the strain of Escherichia coli Nissle 1917 is useful in treatment of gastrointestinal diseases, especially in treatment of ulcerative colitis. This probiotic may constitute a part of treatment of irritable bowel syndrome and diarrhea. The effectiveness of this strain in treatment of Crohn's disease is not clearly established and further research are require. PMID:25380207

    Full Text Available Objective. Functional dyspepsia (FD is a frequent clinical finding in western world. The aim of this study is to compare the efficacy of a ginger and artichoke supplementation versus placebo in the treatment of FD. Methods. A prospective multicentre, double blind, randomized, placebo controlled, parallel-group comparison of the supplement and placebo over a period of 4 weeks was performed. Two capsules/day were supplied (before lunch and dinner to 126 FD patients (supplementation/placebo: 65/61. Results. After 14 days of treatment, only supplementation group (SG showed a significant amelioration (SG: αS=+1.195 MCA score units (u, P=0.017; placebo: αP=+0.347 u, P=0.513. The intercept (α resulted to be significantly higher in SG than in placebo (αS-αP=+0.848 u, P<0.001. At the end of the study, the advantage of SG versus placebo persists without variation (βS-βP=+0.077 u, P=0.542. In SG, a significant advantage is observed for nausea (βS-βP=-0.398 u, P<0.001, epigastric fullness (βS-βP=-0.241, P<0.001, epigastric pain (βS-βP=-0.173 u, P=0.002, and bloating (βS-βP=-0.167 u, P=0.017. Conclusions. The association between ginger and artichoke leaf extracts appears safe and efficacious in the treatment of FD and could represent a promising treatment for this disease.

    Chronic industrial fluoride toxicosis in the forms of dental, skeletal and non-skeletal fluorosis was investigated in 162 villagers (94 males and 78 females) above 15 years of age living in the vicinity of superphosphate fertilizer plants located approximately 12 km south of Udaipur city of Rajasthan, India. Out of these villagers, 90 (55.5%) and 29 (18.0%) were found to be afflicted with mild to severe dental and skeletal fluorosis, respectively. Dental fluorosis characterized with light to deep-brownish bilaterally striated horizontal lines, pits or patches and fine dots or granules was noted on incisor teeth of villagers. Irregular wearing, excessive corrosions (abrasions), dark-brownish pigmentation of exposed cementum and dentine material, diastem as between teeth, pronounced loss of tooth supporting bone with recession and bulging of gingiva (gum) were also present in subjects of older age group (>55 years). Among 29 (18.0%) individuals, mild to moderate manifestations of skeletal fluorosis such as crippling, kyphosis, invalidism and genu-varum syndrome were found. In these fluorotic subjects pain/rigidity in major joints viz. neck, back, hip, knee and shoulder was also found. None of the fluorotic subjects showed evidence of genu-valgum syndrome. Other signs of chronic industrial fluoride intoxication in soft tissues (non-skeletal fluorosis) included colic, intermittent diarrhoea or constipation, bloating, polyuria and polydipsia. These findings indicate that surrounding environment of superphosphate fertilizer plants is contaminated with fluoride emission, which in turn is causing diverse ill health effects in humans which are discussed.

    Full Text Available Abstract Background Rumination syndrome (RS is a functional gastrointestinal disorder (FGD increasingly recognized in children and adolescents. The epidemiology of this condition in school aged children is poorly understood. The main objective of this study was to assess the prevalence of rumination and other related associations in a cohort of Sri Lankan children. Methods Children aged 10-16 years were randomly selected from 8 schools in 4 provinces in Sri Lanka. RS was diagnosed using Rome III criteria. Data was collected using a self administered questionnaire distributed in an examination setting. It was translated into Sinhala, the native language and pretested before distribution. Results A total of 2163 children were included in the study (55% boys, mean age 13.4 years, SD 1.8 years. Prevalence of RS was 5.1% (n = 110; boys 5.1% and girls 5.0%. When symptoms were analyzed, 73.6% reported re-swallowing of regurgitated food, while the rest spat it out. In 94.5% regurgitation occurred during the first hour after the meal. Only 8.2% had daily symptoms while 62.7% had symptoms weekly. Abdominal pain, bloating and weight loss were the commonest symptoms associated with RS (19.1%, 17.3% and 11.8% respectively. No significant association was observed between exposure to stressful events and rumination (p > 0.05. Twenty (18.2% with RS fulfilled Rome III criteria for at least one other FGD. School absenteeism was seen in 11.8% of affected children. Conclusion RS was reasonably common in this cohort of school-aged children and adolescents in Sri Lanka. However, symptoms were severe enough to affect schooling only in 12% of affected children. Around one fifth with RS had at least one other overlapping FGD.

    Full Text Available A cross-sectional study was carried out in Veterinary Clinics, Gondar town, Ethiopia from November 2011 to April 2012. Totally 416 ruminants were recorded in the clinics in which 36 clinical cases (34 bovine and 2 sheep were operated for rumen problem. The overall prevalence of foreign bodies’ was 8.6%. The non-penetrating foreign bodies have higher prevalence than penetrating foreign bodies. The commonly recovered non-penetrating foreign bodies were plastics (36.6%, followed by sack thread (26.8%, rope (16.9%, leather (15.5% and hair (4.2%. The penetrating foreign bodies were wires (51.9% commonly occurred, followed by nail (37.0% and needles (11.1%. The common clinical symptoms observed were recurrent bloat (34.8%, suspended rumination (17.4%, scanty feces (10.9%, anorexia (8.7%, rough hair coat (6.5% and distended abdomen (21.7%. Outcome of this rumenotomy studies were significantly associated with relation to the quantities of foreign bodies recovered. Out of 36 animals operated 24 were well recovered, 4 faced postoperative complication and 8 died. Adult female animals were more affected than younger and male. The present study revealed that inappropriate solid wastes disposed in the study area not only pollute the environment but also have adverse effects on healthy ruminants. In conclusion, detection of the foreign bodies in fore stomach suggested as health risk to ruminants. Therefore, appropriate solid waste disposal system need to implement in the study area to prevent health risk of ruminants and also to protect the environment.

    Full Text Available Introduction: Adrenal incidentalomas (AI are detected in approximately 4-7% of patients in imaging studies. Majority are benign, but careful evaluation is warranted to rule out carcinoma and functional adenomas. Aim: The purpose of presenting these cases is to highlight the approach to management of AI in terms of diagnosis, follow-up, and treatment. Materials and Methods: Seven patients presenting in the endocrine clinic with AI were evaluated for their presenting clinical features and investigated. Results: Case 1 was a 49-year-old female, with adrenal androgen secreting adrenocortical carcinoma with amenorrhoea which was mistaken as menopause. She had minimal hirsutism, which was mistaken as postmenopausal hirsutism. Case 2 was a 39-year-old male, presenting with hyperglycemia found to have Conns′ syndrome with aldosterone producing adenoma on routine ultrasound. Case 3 was a 32-year-old male, presenting with gastritis and bloating, where ultrasound showed bilateral large adrenal masses revealed as diffuse large B cell lymphoma on biopsy. Case 4 was a 21-year-old boy, who had pheochromocytoma misdiagnosed as benign intracranial hypertension (HTN. Case 5 was a 59-year-old hypertensive male, presenting with fever had pheochromocytoma with catecholamine excess, producing fever. Case 6 was isolated adrenal tuberculosis who presented with chronic diarrhea. Conclusion: AI are common, though prevalence varies depending on the reason for scanning, the characteristics of the population studied, and the radiological techniques used. Most are non-secreting cortical adenomas. AI should be evaluated both biochemically and radiologically. When a hormonal disorder is suspected clinically, targeted, diagnostic testing for autonomous cortisol secretion, pheochromocytoma, and hyperaldosteronism is indicated.

    Drospirenone 3 mg/ethinyl estradiol 20 microg (24/4) is a new unique oral contraceptive formulation that combines in a novel dosing regimen the lowest dosage of ethinyl estradiol commonly used today with drospirenone, an innovative progestin. Drospirenone is a compound closely resembling progesterone, but with the antimineralocorticoid and antiandrogenic properties of a related therapeutic agent, the diuretic, antihypertensive and androgen receptor antagonist, 17alpha-spironolactone. The prolongation of hormonally active pills in the monthly drospirenone/ethinyl estradiol cycle from 21 days to 24 days, followed by 4 days of inactive pills, is an interesting variant of the recently developed extended pill regimens (1). Recent contraceptive research has focused on improving side effect profiles and providing noncontraceptive health and lifestyle advantages. Many of these benefits are now supported with evidence-based medicine (2). Most available oral contraceptives improve cycle regularity, menstrual pain, excessive menstrual flow and acne. However, weight gain, bloating, food cravings, breast tenderness and mood alterations (especially irritability and depression and the complex of affective, behavioral and somatic symptoms of premenstrual syndrome [PMS] and the severe form of PMS, premenstrual dysphoric disorder [PMDD]) are not generally improved with the traditional oral contraceptive formulations (3). Drospirenone/ethinyl estradiol 24/4 is currently the only hormonally based contraceptive regimen with large, randomized, controlled trials demonstrating efficacy for PMDD. It has received U.S. Food and Drug Administration (FDA) indications not only for the prevention of pregnancy but also for PMDD and for moderate acne vulgaris in women who choose oral contraception for birth control (4, 5).
