    Efficient cleansing of the colon before a colonoscopy or a radiological examination is essential. The osmotically acting cathartics (those given the Anatomical Therapeutic Chemical code A06AD) currently used for this purpose comprise products based on three main substances: sodium phosphate......, combinations of polyethylene glycol and electrolyte lavage solutions (PEG-ELS), and magnesium citrate. All these preparations give adequate cleansing results and have similar profiles in terms of the frequency and type of mild to moderate adverse effects. However, serious adverse events, such as severe...... hyperphosphatemia and irreversible kidney damage owing to acute phosphate nephropathy, have been reported after use of sodium-phosphate-based products. The aim of this Review is to provide an update on the potential safety issues related to the use of osmotically acting cathartics, especially disturbances of renal...

    In a two-part study, two groups of 100 outpatients each were randomly assigned a colon preparation. In part 1, a standard 1-day diet/cathartic combination was compared with Golytely. In part 2, diet/cathartics was compared with Golytely plus Dulcolax (bisacodyl). The standard preparation provided good or excellent feces removal in 81 (80%) of 101 subjects. Golytely alone was successful in only 21 (53%) of 40 patients, but Golytely followed by Dulcolax achieved good or excellent feces removal in 31 (82%) of 38. Degraded mucosal coating with Golytely alone, due to excessive fluid retention, was also corrected by the addition of Dulcolax. Golytely alone is not an adequate method of colon cleansing for double-contrast barium enema, but Golytely plus Dulcolax is as effective as the standard preparation. PMID:6609598

  10. Apparent tolerance of turkey vultures (Cathartes aura) to the non-steroidal anti-inflammatory drug diclofenac

    The nonsteroidal anti-inflammatory drug diclofenac is extremely toxic to Old World Gyps vultures (median lethal dose 0.1?0.2 mg/kg), evoking visceral gout, renal necrosis, and mortality within a few days of exposure. Unintentional secondary poisoning of vultures that fed upon carcasses of diclofenac-treated livestock decimated populations in the Indian subcontinent. Because of the widespread use of diclofenac and other cyclooxygenase-2 inhibiting drugs, a toxicological study was undertaken in turkey vultures (Cathartes aura) as an initial step in examining sensitivity of New World scavenging birds. Two trials were conducted entailing oral gavage of diclofenac at doses ranging from 0.08 to 25 mg/kg body weight. Birds were observed for 7 d, blood samples were collected for plasma chemistry (predose and 12, 24, and 48 h and 7 d postdose), and select individuals were necropsied. Diclofenac failed to evoke overt signs of toxicity, visceral gout, renal necrosis, or elevate plasma uric acid at concentrations greater than 100 times the estimated median lethal dose reported for Gyps vultures. For turkey vultures receiving 8 or 25 mg/kg, the plasma half-life of diclofenac was estimated to be 6 h, and it was apparently cleared after several days as no residues were detectable in liver or kidney at necropsy. Differential sensitivity among avian species is a hallmark of cyclooxygenase-2 inhibitors, and despite the tolerance of turkey vultures to diclofenac, additional studies in related scavenging species seem warranted.

    Variation is key to the adaptability of species and their ability to survive changes to the Earth's climate and habitats. Plasticity in movement strategies allows a species to better track spatial dynamics of habitat quality. We describe the mechanisms that shape the movement of a long-distance migrant bird (turkey vulture, Cathartes aura) across two continents using satellite tracking coupled with remote-sensing science. Using nearly 10 years of data from 24 satellite-tracked vultures in four distinct populations, we describe an enormous amount of variation in their movement patterns. We related vulture movement to environmental conditions and found important correlations explaining how far they need to move to find food (indexed by the Normalized Difference Vegetation Index) and how fast they can move based on the prevalence of thermals and temperature. We conclude that the extensive variability in the movement ecology of turkey vultures, facilitated by their energetically efficient thermal soaring, suggests that this species is likely to do well across periods of modest climate change. The large scale and sample sizes needed for such analysis in a widespread migrant emphasizes the need for integrated and collaborative efforts to obtain tracking data and for policies, tools and open datasets to encourage such collaborations and data sharing.

    We aimed to compare iohexol vs. diatrizoate as fecal/fluid tagging agents for computed tomography colonography (CTC) regarding examination quality. Forty prospective patients (M:F = 23:17; 63 ± 11.6 years) received CTC using 50 mL (350 mgI/mL) oral iohexol for tagging. Forty other indication-matched, age-matched, and sex-matched patients who underwent CTC using 100 mL diatrizoate for tagging and otherwise the same technique, were retrospectively identified. Two groups were compared regarding overall examination quality, per-patient and per-segment scores of colonic bubbles (0 [no bubbles] to 5 [the largest amount]), and the volume, attenuation, and homogeneity (untagged, layered, and homogeneous) of the residual colonic fluid. The iohexol group demonstrated a greater amount of colonic bubbles than the diatrizoate group: mean per-patient scores ± SD of 1.2 ± 0.8 vs. 0.7 ± 0.6, respectively (p = 0.003); and rates of segments showing ≥ grade 3 bubbles of 12.9 % (85/659) vs. 1.6 % (11/695), respectively (p = 0.001). Residual colonic fluid amount standardized to the colonic volume did not significantly differ: 7.2 % ± 4.2 vs. 7.8 % ± 3.7, respectively (p = 0.544). Tagged fluid attenuation was mostly comparable between groups and the fluid was homogeneously tagged in 98.7 % (224/227) vs. 99.5 % (218/219) segments, respectively (p = 0.344). Iohexol caused more colonic bubbles when used during cathartic CTC. Otherwise, examination quality was similarly adequate with both iohexol and diatrizoate. (orig.)

  14. Activation Effect of Cathartic Natural Compound Rhein to CFTR Chloride Channel

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    The cystic fibrosis transmembrane conductance regulator (CFTR) is a cAMP-activated chloride channel expressed in intestinal exocrine glands, which plays a key role in intestinal fluid secretion. A natural anthraquinone activator of CFTR Cl- channel, rhein, was identified by screening 217 single compounds from Chinese herbs via a cellbased halide-sensitive fluorescent assay. Rhein activates CFTR Cl- transportation in a dose-dependent manner in the presence of cAMP with a physiological concentration. This study provides a novel molecular pharmacological mechanism for the laxative drugs in Traditional Chinese Medicine such as aloe, cascara and senna.

    The purpose of this study was to prospectively compare participant experience and preference of limited preparation computed tomography colonography (CTC) with full-preparation colonoscopy in a consecutive series of patients at increased risk of colorectal cancer. CTC preparation comprised 180 ml diatrizoate meglumine, 80 ml barium and 30 mg bisacodyl. For the colonoscopy preparation 4 l of polyethylene glycol solution was used. Participants' experience and preference were compared using the Wilcoxon signed rank test and the chi-squared test, respectively. Associations between preference and experience parameters for the 173 participants were determined by logistic regression. Diarrhoea occurred in 94% of participants during CTC preparation. This side effect was perceived as severely or extremely burdensome by 29%. Nonetheless, the total burden was significantly lower for the CTC preparation than for colonoscopy (9% rated the CTC preparation as severely or extremely burdensome compared with 59% for colonoscopy; p<0.001). Participants experienced significantly more pain, discomfort and total burden with the colonoscopy procedure than with CTC (p<0.001). After 5 weeks, 69% preferred CTC, 8% were indifferent and 23% preferred colonoscopy (p<0.001). A burdensome colonoscopy preparation and pain at colonoscopy were associated with CTC preference (p<0.04). In conclusion, participants' experience and preference were rated in favour of CTC with limited bowel preparation compared with full-preparation colonoscopy. (orig.)

Data collected via questionnaires were used to evaluate quantitative variables complemented by heuristics while aiming at qualitatively categorize the areas of cathartic states in the context of philosophical and spiritual aspects of long-distance running. The study findings objectify philosophical and spiritual aspects affecting personalities of long-distance runners. The study findings have shown that catharsis represents a relevant philosophical and spiritual aspect affecting long-distance running. We assume that authentic experience of catharsis and its effects motivates runners to perform regular physical activity. The analysis of philosophical and spiritual aspects of long-distance running has revealed a multi-spectral holistic relevance based on the transfer affecting a specific way of life, spectrum of values, ethical personality traits, and also the quality of long-distance runners’ lives.

    Ever since Felipe Calderón declared the war on drugs at the beginning of his presidency in 2006, violence has drastically permeated Mexican society. In this paper, I will focus on the different uses of dark humour and irony in the representation of the mutilated and abject body in contemporary Mexican culture, especially in literature. Therefore, I will take into consideration the Mexican tradition of humoristic approaches to death, which might seek a cathartic effect in dealing with violence...

    Monsters have attracted our imagination throughout times, even in an apparently rational and pragmatic age such as ours. Being one of the monsters of the new millennium, the zombie is now a permanent figure of popular culture, both embodying society’s most terrible fears and exploring audience’s desire for violent cathartic experiences. Of African origins, the zombie has been popularised by American cinema and spread across cultures and media. Although with no great tradition of horror, Portu...

    The importance of olfaction for various avian behaviors has become increasingly evident. So far, the use of olfaction for food detection among raptors has only been demonstrated for Cathartes vultures. The Oriental honey buzzard (Pernis orientalis) is a resident and migrant in Taiwan and regularly forages in apiaries. One of its foods in apiaries is yellow pollen dough, a softball-sized mixture of pollen, soybeans, and sugar that beekeepers provide as a supplementary food for bees. Given that...

    We prospectively assessed the feasibility and acceptance of computerized tomographic colonography (CTC) without bowel cathartic preparation in elderly patients after incomplete colonoscopy. A total of 136 patients underwent CTC without cathartic preparation. The time delay between conventional colonoscopy and CTC ranged between 3 and 20 days, depending on the clinical situation. Before CTC, fecal tagging was achieved by adding diatrizoate meglumine and diatrizoate sodium to regular meals. CTCs were interpreted using a primary two-dimensional (2D) approach and 3D images for further characterization. Patients were interviewed before and 2 weeks after CTC to assess preparation acceptance. CTC was feasible and technically successful in all the 136 patients. Fecal tagging was judged as excellent in 113 (83%) patients and sufficient in 23 (17%). Average CT image interpretation time was 14.8 min. Six (4.4%) cases of colorectal cancer and nine (6.6%) large polyps were detected, as well as 23 (11.3%) extracolonic findings of high clinical importance. No major side effect occurred, although 25% patients reported minor side effects, especially diarrhea. Overall, 76/98 patients replied that they would be willing to repeat the test if necessary. CTC without cathartic preparation is a technically feasible and safe procedure to complete a colonic study in the elderly, prompting its use in clinical practice. (orig.)

    Turkey Vultures (Cathartes aura), were surveyed monthly in Cuba from March 1982-January 1983. A total of 25371 vultures were tallied in 7186 km (3.5 vultures/transect km) of roadside counting along main highways leading from the city of La Habana (northwestern Cuba) to the city of Las Tunas (southeast). Numbers of vultures counted declined substantially beyond 200 m from the transect road. Density of vultures observed within 200 m of the road along the transect route was 0.06/ha. Highest counts were obtained in March, April and June. Turkey Vulture flying activity was greatest during the periods 0900-1200 H and 1400-1700 H.

    The incidence of Helicobacter pylori (H. pylori) infection is rapidly decreased in Japan. H. pylori infection is mainly acquired in the first 2 years life and the risk of infection declines rapidly after 5 years of age. Person-to-person transmission in the family appears to be the predominant and in the population with low prevalence, several studies showed the infected mother is likely to be the main source of the infection. H. pylori can be detected from vomitus, saliva and cathartic stools and the possibility of source of infection. Waterborne infection is unlikely in the developed countries. PMID:23967662

    Second-generation anticoagulant rodenticides can give rise to unexpected casualties in nontarget species in zoos. The first two offspring of a pair of turkey vultures (Cathartes aura) died of brodifacoum toxicosis. The adult birds fed rodenticide-killed mice to their offspring. There are previous case reports of small carnivorous birds (Dacelo novae-guinae and Tockus deckeni) killed eating poisoned (difenacoum and brodifacoum) mice. Even a granivorous species (Rollulus roulroul) died, probably by contamination of its food by cockroaches that transported the rodenticide. PMID:12216801

    Anna Artwińska

    2015-01-01

    Full Text Available The article discusses select literary images and presentations of March 1968, which are treated as an example of a postcatastrophic narration. The author states that the events of the years 1967-1968 are often depicted in Polish literature as a kind of a “recurring catastrophe” – predicting an event of the calibre of the Holocaust. Similarities and parallels can be noticed on the artistic level (ways of representation and ideological (judgement of events. Consequently, the catastrophe does not fulfil its cathartic function and does not become a breakthrough, instead its characteristic features are repetitions and new configurations. Finally, the author asks whether, and to what extent, Polish remembrance of March overlaps with the remembrance of the Holocaust, and to what degree the struggle with anti-Semitism in 1967-1968 was simultaneously a struggle with anti-Semitism during WWII.

    Vultures are highly reliant on their sensory systems for the rapid detection and localization of carrion before other scavengers can exploit the resource. In this study, we compared eye morphology and retinal topography in two species of New World vultures (Cathartidae), turkey vultures (Cathartes...... aura), with a highly developed olfactory sense, and black vultures (Coragyps atratus), with a less developed sense of olfaction. We found that eye size relative to body mass was the same in both species, but that black vultures have larger corneas relative to eye size than turkey vultures. However, the...... species are similar and that vision plays an equally important role in the biology of both species, despite the apparently greater reliance on olfaction for finding carrion in turkey vultures.

    Helicobacter pylori (H. pylori) infection is mainly acquired in the first 2 or 3 years and the risk of infection declines rapidly after 5 years of age. In developing countries, acquisition age of the infection is probably lower than in developed countries. In Japan, main transmission route is intrafamilial and mother to children infection is most important. But in developing countries, some reports suggest that extrafamilial infection is more important. The famous paper revealed that H. pylori can be cultivated from vomitus, saliva and cathartic stools and the possibility of source of H. pylori infection. Bed sharing, large number of family members, delayed weaning from a feeding bottle, regurgitated gastric juice in the mother's mouth are reported as risk factors of the infection. PMID:19999106

    Aloe vera has been used for centuries as a topical treatment for various conditions and as a cathartic. An amorphous hydrogel dressing derived from the aloe plant (Carrasyn Gel Wound Dressing, Carrington Laboratories, Inc., Irving, TX) is approved by the Food and Drug Administration for the management of Stages I through IV pressure ulcers. To evaluate effectiveness of this treatment, 30 patients were randomized to receive either daily topical application of the hydrogel study dressing (acemannan hydrogel wound dressing) or a moist saline gauze dressing. Complete healing of the study ulcer occurred in 19 of 30 subjects (63%) during the 10-week observation period. No difference was observed in complete healing between the experimental and the control groups (odds ratio 0.93, 95% CI 0.16, 5.2). This study indicates that the acemannan hydrogel dressing is as effective as, but is not superior to, a moist saline gauze wound dressing for the management of pressure ulcers. PMID:10326343

    This discussion of an episode of mass hysteria in a Malay college in West Malaysia examines stress and conflict in relation to the interpretive process within a specific social setting. Unlike previous studies, which conceptualize mass hysteria as a cathartic response to accumulated stress, the present study treats stress as a matter of definition in a specific sociocultural context rather than as an objective given from which predictions can be made. Objections are raised to the logic of explanations that attribute mass hysteria to environmental stress. What is of concern is how meanings are assigned to events that are experienced as stressful, how participants and observers explain these events, and the consequences that follow from their interpretations.

    Full Text Available The activity of vertebrates that feed on corpses can modify the chronology of the decomposition process and interfere with postmortem interval estimates. Further, by destroying the soft parts of the cadaver, scattering, burying or causing the disappearance of bones, it can entirely change the crime scene. In this study, we simulated a clandestine cemetery in an area of Cerrado located inside a farm in Brasília, Distrito Federal. Three domestic pigs of the size of a human of about 60 kg were placed on the ground in different periods of 2010 and 2011. We recorded four species of birds and one of mammal eating the carcasses: 1 Cathartidae: Coragyps atratus (Bechstein, 1973, Cathartes aura (Linnaeus, 1758, Sarcoramphus papa (Linnaeus, 1758; 2 Falconidae: Caracara plancus (Miller, 1777; and 3 Felidae: Leopardus pardalis (Lund, 1840. The behavior of these animals interfered in the decomposition process and resulted in the dispersion and loss of bony parts.

  10. Effect of alcohol on internally deposited Am-241 in the baboon: a pilot study

    International Nuclear Information System (INIS)

    The efficacy of ethyl alcohol in enhancing the excretion of Am-241 from the baboon has been tested. Alcohol enhances Am-241 excretion via the fecal route by a factor of about 2.5. However, there is a corresponding increase in fecal volume, and no significant change in the concentration of the nuclide in the feces. Other cathartics tested caused increased fecal volumes with no change in amount of activity excreted leading to a decreased concentration of the nuclide in the feces. Alcohol is not as effective as DTPA in removing Am-241 from the body. Preliminary results suggest that alcohol has little or no enhancement effect on the decorporation capability of DTPA

    In the Oath, Hippocrates does not cite Dionisus at all. In Greek mythology, Apollus and Dionisus are, in some way, absolutely conflicting gods, nonetheless complementary each to the other; both are devoted to healing practices, one through his téchne founded on scientific knowledge, the other throught collective cathartic processes. The author conjectures that the exclusion of Dionisus from the medical Hippocratic scene means the birth of a medical deontology founded on the contrast between profecy and extasis, knowledge and happiness, order and change, health and disease. Balancing these cultural different aspects of therapy and cure, Bioethics could reunify the concepts of health, sickness and disease in the idea of Life, continuosly changing and developing. The curing process needs synthesis--invoking Apollus to rescover Dionisus mask. PMID:23057201

  12. Automated image-based colon cleansing for laxative-free CT colonography computer-aided polyp detection

    International Nuclear Information System (INIS)

    Purpose: To evaluate the performance of a computer-aided detection (CAD) system for detecting colonic polyps at noncathartic computed tomography colonography (CTC) in conjunction with an automated image-based colon cleansing algorithm. Methods: An automated colon cleansing algorithm was designed to detect and subtract tagged-stool, accounting for heterogeneity and poor tagging, to be used in conjunction with a colon CAD system. The method is locally adaptive and combines intensity, shape, and texture analysis with probabilistic optimization. CTC data from cathartic-free bowel preparation were acquired for testing and training the parameters. Patients underwent various colonic preparations with barium or Gastroview in divided doses over 48 h before scanning. No laxatives were administered and no dietary modifications were required. Cases were selected from a polyp-enriched cohort and included scans in which at least 90% of the solid stool was visually estimated to be tagged and each colonic segment was distended in either the prone or supine view. The CAD system was run comparatively with and without the stool subtraction algorithm. Results: The dataset comprised 38 CTC scans from prone and/or supine scans of 19 patients containing 44 polyps larger than 10 mm (22 unique polyps, if matched between prone and supine scans). The results are robust on fine details around folds, thin-stool linings on the colonic wall, near polyps and in large fluid/stool pools. The sensitivity of the CAD system is 70.5% per polyp at a rate of 5.75 false positives/scan without using the stool subtraction module. This detection improved significantly (p = 0.009) after automated colon cleansing on cathartic-free data to 86.4% true positive rate at 5.75 false positives/scan. Conclusions: An automated image-based colon cleansing algorithm designed to overcome the challenges of the noncathartic colon significantly improves the sensitivity of colon CAD by approximately 15%.

    1999-01-01

    Bacterial translocation leading to subsequent infectious complications is a significant determinant of outcome in acute hemorrhagic pancreatitis (AHP). The colonic ileus and impaired intestinal barrier function that often accompany AHP may predispose to translocation. Sennoside is a naturally occurring cathartic and choleretic agent that stimulates intestinal mucous secretion and has potent promotility effects. The impact of sennoside-induced intestinal motility and secretory function on bacterial translocation and survival was studied in a rat model of AHP. Severe acute pancreatitis was induced in rats by the intraductal infusion of 2% sodium deoxycholate (DCA, 0.4 ml/kg). A group of sham-operated rats (group A) received intraductal saline, whereas experimental animals were subsequently administered distilled water (group B) or sennoside solution (group C) by gavage every 8 h. After 48 h, intestinal transit of fluorescein isothiocyanate-labeled dextran, serum endotoxin, and amylase levels, and bacterial translocation to mesenteric lymph nodes (MLNs) and pancreatic tissue were determined. The pancreas and intestine were sampled for histologic study. All group A animals survived and did not develop pancreatitis or endotoxemia, whereas groups B and C all demonstrated severe hemorrhagic pancreatitis with evidence of necrosis. Mortality at 48 h was 55% in group B versus 12.5% in group C. Inhibition of intestinal motility was noted in 40% versus 20%, and endotoxin levels were 61.36+/-28.26 pg/L versus 5.41+/-3.58 pg/L in group B versus group C rats, respectively (ptranslocation of endotoxin and bacteria, restored intestinal motility, increased mucous secretion, and reduced mortality in a model of acute hemorrhagic pancreatitis in the rat. Other cathartics may have similar properties and may be useful in preventing infectious complications in acute pancreatitis. PMID:9888659

    Falconiformes include most of the predatory birds, they play crucial role in maintaining the balance of ecology system. To further illustrate the phylogenetic status for the species of Falconiformes, the entire mitochondrial DNA (mtDNA) genome of Falco naumanni was amplified and sequenced, further phylogenetic analysis was performed by incorporating with other 8 entire mtDNA genomes representing 8 species of predatory birds by taking the Apus apus and Haematopus ater as out-groups. Our results indicated that the mtDNA genome of F. naumanni includes 17,370 base pairs in length, which has the similar organization and gene order with other mtDNA genomes of the species belonging to Falconiformes. Further phylogenetic analyses supported that the F. naumanni clustered with other species of Falconidae, which formed the sister group of Accipitridae, Cathartes aura located at the basal position with Haematopus ater. In addition, Pandion haliaetus was clustered with other species of Accipitridae, which was conflict with the traditional classification system by taking P. haliaetus as an independent Familia of Falconidae.

    2009-01-01

    Full Text Available The paper focuses on the problem of identity in A. L. Kennedy’s novel So I’m Glad and the short story Original Bliss. It argues that the structure of identity in the aforementioned works partly accounts for the ethics advanced in Kennedy’s work. At the centre of each work there is a romantically involved couple whose love stories offer interesting examples of a relationship between self and other. Kačkutė be­lieves that the other in Kennedy‘s writing is peculiar­ly positioned neither in or outside the subject, it cor­responds to Judith Butler’s idea of the constitutive outside that is brewed inside the subject. Either way such dialectics of the self and other results in a po­sitive identity development. Such change is marked by traumatic and physically painful experiences, but results in a cathartic moment that suggests the pro­found ethics underlying Kennedy‘s artistic project.

    Full Text Available In this paper a detailed review of myristicin is reported. Numerous literatures report that myristicin is responsible for hallucinogenic effects, which induced by the consumption of nutmeg due to its metabolism structure of 3-methoxy-4,5-methylendioxyamphetamine (MMDA. Minimum dosage of nutmeg that can cause psychogenic effect is 5 g (ground nutmeg with 1 to 2 mg myristicin content and this dosage is considered as ‘toxic dose’. At higher dosage of myristicin death may occur. Additionally, Myristicin poisoning can lead to many health problems that related to brain problem. Those symptoms usually occur 3 to 6 hours after ingestion of myristicin or foodstuffs containing it, and effects may persist up to 72 hours. California Poison Control System (CPCS electronic database 72.3% exposures between 1997 and 2008 that were intentional for recreational purposes (between ages 13 and 20 years old. The remaining considered as unintentionally exposed. Between 1998 to 2008, Texas Poison Center Network (TPCN received seventeen nutmeg poisoning and 64.7% from that cases involved abuse, and the rest was unintentional exposure. Most of the nutmeg exposures were via the oral route and minor cases of nutmeg exposure occurred through insufflated nutmeg, unintentional dermal and ocular exposures. Nutmeg also has been misused by mixing it with other drugs in order to get “high”. For intoxication cases, treatments like decontamination (cathartic, charcoal, dilution, fresh air, IV fluids and supportive care (benzodiazepines will be provided to reduce the effects.

  18. Il razzismo del lager nazista: il confine fra realtà e finzione nel Dio Kurt di Moravia

    Full Text Available This paper aims to explore the question of racism in the Nazi concentration camp as it emerges in Moravia’s 1968 play Dio Kurt. The focus of Moravia’s play is on Oedipus, a Jew detained in a Nazi concentration camp, and Fate, personified by the camp commander, Colonel Kurt, who forces Oedipus-Saul and his family to enact in reality the Sophoclean tragedy Oedipus Rex. Through a series of barbarous machinations derived by Kurt, the boundaries between reality and fiction that characterize a work of fiction and the artistic process more generally, are surpassed. If, as Levinas maintains, in Reflections on the Philosophy of Hitlerism (1934, racism and Nazism question the very essence of humanity in man in the moment in which they ‘enslave’ being to the body, and if, as Agamben asserts in Homo sacer (1995, the concentration camp is the biopolitical space par excellence, the interpretive consequences on a reading of Moravia’s play are manifold. In Dio Kurt, the Jews are reduced to a biological state, to ‘bare life’ to use Benjamin’s term, through the manipulation of the artistic tradition that is transformed into an instrument in the annihilation of humanity precisely when it loses its status of cathartic fiction.

    This study delivered a daily diary to 67 HIV-infected men who have sex with men (MSM) between 16 and 24 years old for 66 days to measure HIV-risk behaviors and other psychosocial variables via two diary modalities: internet (accessible via any web-enabled device) and voice (accessible via telephone). Participants were randomized to complete one diary modality for 33 days before switching to the second modality for 33 days. The study was implemented in three urban HIV health care centers in the United States where participants were receiving services. Through diary data and qualitative interview data, we examined the feasibility and acceptability of the dairies and identified barriers and facilitators of dairy compliance. Results show high participant retention in the daily diary (93.4 %) and high compliance for the number of dairies completed (72.4 %). Internet diaries were preferred by 92 % of participants and completed at a significantly higher rate (77.5 %) than voice diaries (67.7 %). Facilitators included opportunities for self-reflection and cathartic sharing, monetary compensation, relationships with study staff, and daily reminders. Barriers included being busy or not having privacy at the time of reminders, forgetting, and falling asleep. Participants also described barriers and facilitators unique to each modality. Overall, both modalities were feasible and acceptable for use with our sample of HIV-infected MSM. PMID:26837629

My new project, still in its early stages, asks whether the concept and ritual practice of purification can be used to enhance moral repair in individuals and to serve the restoration of social order in the aftermath of atrocity and systemic human rights abuses.

  1. [The potential use of ayahuasca in psychiatry].

    2016-06-01

    Ayahuasca is a decoctum made of admixture plants containing dimethyltryptamine and harmine. For millennia it has been used as a central element of spiritual, religious, initiation, and other - foremost healing - rituals, originally by the indigenous groups of the Amazon basin and later by the mestizo populations of the region. During the last two decades the brew has raised increased scientific and lay interest about its healing potentials within the framework of Western therapeutic settings. The typical ayahuasca effects consist of strong somatic reactions, vivid visions, relived personal memories, cathartic emotions, and insightful, introspective experiences when the emerging mental contents take different context and get deeper perspectives. The ayahuasca-experience can be exhausting necessitating the presence of an experienced leader for helping participants to pass difficult phases and for maximizing therapeutic benefits. No health damaging adverse effect has been confirmed thus far as result of its well-structured, institutionalized use. The scientific investigation of ayahuasca is hindered by legal issues, methodical problems, and sociocultural preconceptions. The present review outlines the therapeutic potentials of ayahuasca use in psychiatry with its psychobiological and spiritual background. PMID:27390204

    Throughout the world, populations of scavenger birds are declining rapidly with some populations already on the brink of extinction. Much of the current research into the factors contributing to these declines has focused on exposure to drug residues, lead, and other toxins. Despite increased monitoring of these declining populations, little is known about infectious diseases affecting scavenger bird species. To assess potential infectious disease risks to both obligate and facultative scavenger bird species, we performed a serosurvey for eleven potential pathogens in three species of scavenging birds in California: the California condor (Gymnogyps californianus), turkey vulture (Cathartes aura) and golden eagle (Aquila chrysaetos). California condors were seropositive for avian adenovirus, infectious bronchitis virus, Mycoplasma gallisepticum, avian paramyxovirus-2, West Nile virus (WNV) and Toxoplasma gondii. Golden eagles were seropositive for avian adenovirus, Chlamydophila psittaci and Toxoplasma gondii, and turkey vultures were seropositive for avian adenovirus, Chlamydophila psittaci, avian paramyxovirus-1, Toxoplasma gondii and WNV. Risk factor analyses indicated that rearing site and original release location were significantly associated with a positive serologic titer to WNV among free-flying condors. This study provides preliminary baseline data on infectious disease exposure in these populations for aiding in early disease detection and provides potentially critical information for conservation of the endangered California condor as it continues to expand its range and encounter new infectious disease threats.

    1988-01-01

    Use of conditioned taste aversion (CTA) has been proposed to reduce consumption of California condor (Gymnogyps californianus) eggs by ravens (Corvus corax). Although landrin has induced aversions in ravens and other birds, no data were available on behavioral and physiological effects of landrin on condors, non-target birds that might consume treated eggs. Because condors are endangered, we selected taxonomically related surrogates to approximate the effects on condors of acute oral doses of landrin. Seven black vultures (Coragyps atratus), 2 turkey vultures (Cathartes aura), and 2 king vultures (Sarcoramphus papa) received landrin and placebo treatments 1 week apart. Plasma cholinesterase (ChE) activity was monitored at zero, 3, and 24 hours posttreatment, and behavioral observations were made for 2 hours posttreatment. The doses tested were nonlethal, and ChE levels approached normal within 24 hours after treatment. Only the frequency of vomiting differed statistically between the placebo and landrin treatment. We conclude that with appropriate precautions, landrin can be used in applications of CTA to discourage consumption of condor eggs by ravens, while posing no apparent risk to reintroduced condors.

  4. Anorexia, masochism, self-mutilation, and autoerotism: the spider mother.

    In summary, both self-mutilators and eating-disordered individuals come from dysfunctional homes with a very controlling mother and usually absent father. They often have a history of trauma. They are depressed and obsessive, attached to their mothers, who discourage attempts at emancipation. The symptoms serve the purpose of keeping them as little girls with negative feelings toward menstruation, sexual maturity, development, and femininity in general. These symptoms comprise self-destructive behavior in the service of removing sexual thoughts, temptation, and activities. Favazza (1987) included both eating disorders and self mutilation in his "deliberate self-harm syndrome." The symptoms, whether they be anorexic, bulimic, or a form of self-mutilation are seen as "autoerotic in nature and a substitute for normal masturbation" (Hull & Lane, 1988). Eating disorders and delicate self-mutilation are said to have "a cathartic, self-purifying, function in that they modulate states of anxiety, sexual tension, anger or dissociated emptiness, and they bring about a tremendous quasi-physical sense of relief" (Cross, 1993, p. 50). These patients' use of substitutes prevents maturation and growth as women, causing regression to pregenital phases with the use of pregenital defenses, and the demise of the demands of puberty and mature sexuality.

  5. Catharsis: Psychoanalysis and the theatre.

    Science.gov (United States)

    Vives, Jean-Michel

    2011-08-01

    The notion of catharsis, in relation to tragedy, was introduced by Aristotle in his work Poetics. Over the centuries, Aristotle's innovative and enigmatic reference to this process has been widely commented on and given rise to intense controversy. In 1895, Freud and Breuer reconsidered this notion in their Studies on Hysteria, where they present the so-called cathartic therapeutic method. It is not, however, this aspect of psychoanalytical theory that the author of this article seeks to elucidate: drawing on a detailed study of the references to tragic catharsis in the work of Freud and Lacan, the author proposes to examine their implications for psychoanalytic treatment.With specific reference to Freud's article Psychopathic characters on the stage (1905) and Lacan's commentary on Sophocles' Antigone (1960), the author argues that catharsis is to be understood not so much as a mechanism of discharge linked to abreaction, but rather as the actual analytic process itself during which the Subject is 'unveiled' and thus faced with the enigma of his own desire.

    The Foundations works of the bridge over the the Danube River II has involved a new technical challenge due to the cathartics of depth and diameter of the piles, and the logistical and human, due to the hard environmental conditions for the execution. This work, awarded to FCC. Construction company in its two contracts. Access to the bridge and Main Bridge has required on the differenced sites, the use of a wide range of foundation systems, since driven precast piles to in in situ pile with permanent casing, installed by vibrating systems and excavated with benoto grabs systems. The enormous responsibility of this phase is evident in the intense camping of characterization tests with static load tests, dynamic and Osterberg cells, as well as control the campaign with Cross-hole tests in 100% of the piles in situ executed, that has allowed no only ensure the highest level of quality on the foundation elements, but also to take the most of the mechanical characteristics of soils provided. The complexity of the execution of more than 24,000 ml pile executed along the more than 2 years duration of the work reach the maximum expression in the more than 6,900 ml of in situ pile made from marine resources, with a maximum depths up to 80 m with 2 m diameter pile. The article intends to give an overview of the site and the execution, associating the different foundation methods used, and the problems that were detected. (Author)

    Full Text Available Anthraquinones are a class of aromatic compounds with a 9,10-dioxoanthracene core. So far, 79 naturally occurring anthraquinones have been identified which include emodin, physcion, cascarin, catenarin, and rhein. A large body of literature has demonstrated that the naturally occurring anthraquinones possess a broad spectrum of bioactivities, such as cathartic, anticancer, anti-inflammatory, antimicrobial, diuretic, vasorelaxing, and phytoestrogen activities, suggesting their possible clinical application in many diseases. Despite the advances that have been made in understanding the chemistry and biology of the anthraquinones in recent years, research into their mechanisms of action and therapeutic potential in autoimmune disorders is still at an early stage. In this paper, we briefly introduce the etiology of autoimmune diabetes, an autoimmune disorder that affects as many as 10 million worldwide, and the role of chemotaxis in autoimmune diabetes. We then outline the chemical structure and biological properties of the naturally occurring anthraquinones and their derivatives with an emphasis on recent findings about their immune regulation. We discuss the structure and activity relationship, mode of action, and therapeutic potential of the anthraquinones in autoimmune diabetes, including a new strategy for the use of the anthraquinones in autoimmune diabetes.

  8. Novel method for digital subtraction of tagged stool in virtual colonoscopy

    Colon cancer is one of the most frequent causes of death. CT colonography is a novel method for the detection of polyps and early cancer. The general principle of CT colonography includes a cathartic bowel preparation. The resulting discomfort for patients leads to limited patient acceptance and therefore to limited cancer detection rates. Reduced bowel preparation, techniques for stool tagging, and electronic cleansing, however, improve the acceptance rates. Hereby, the high density of oral contrast material highlights residual stool and can be digitally removed. Known subtraction methods cause artifacts: additional 3D objects are introduced and small bowel folds are perforated. We propose a new algorithm that is based on the 2 nd derivative of the image data using the Hessian matrix and the following principal axis transform to detect tiny folds which shall not be subtracted together with tagged stool found by a thresholding method. Since the stool is usually not homogenously tagged with contrast media a detection algorithm for island-like structures is incorporated. The interfaces of air-stool level and colon wall are detected by a 3-dimensional difference of Gaussian module. A 3-dimensional filter smoothes the transitions between removed stool and colon tissue. We evaluated the efficacy of the new algorithm with 10 patient data sets. The results showed no introduced artificial objects and no perforated folds. The artifacts at the air-stool and colon tissue-stool transitions are considerably reduced compared to those known from the literature.

    The purpose was to evaluate low-dose CT colonography without cathartic cleansing in terms of image quality, polyp visualization and patient acceptance. Sixty-one patients scheduled for colonoscopy started a low-fiber diet, lactulose and amidotrizoic-acid for fecal tagging 2 days prior to the CT scan (standard dose, 5.8-8.2 mSv). The original raw data of 51 patients were modified and reconstructed at simulated 2.3 and 0.7 mSv levels. Two observers evaluated the standard dose scan regarding image quality and polyps. A third evaluated the presence of polyps at all three mSv levels in a blinded prospective way. All observers were blinded to the reference standard: colonoscopy. At three times patients were given questionnaires relating to their experiences and preference. Image quality was sufficient in all patients, but significantly lower in the cecum, sigmoid and rectum. The two observers correctly identified respectively 10/15 (67%) and 9/15 (60%) polyps {>=}10 mm, with 5 and 8 false-positive lesions (standard dose scan). Dose reduction down to 0.7 mSv was not associated with significant changes in diagnostic value (polyps {>=}10 mm). Eighty percent of patients preferred CT colonography and 13% preferred colonoscopy (P<0.001). CT colonography without cleansing is preferred to colonoscopy and shows sufficient image quality and moderate sensitivity, without impaired diagnostic value at dose-levels as low as 0.7 mSv. (orig.)

    Long-duration space missions (LDM) place unique physical, environmental and psychological demands on crewmembers that directly affect their ability to live and work in space. A growing body of research on crews working for extended periods in isolated, confined environments reveals the existence of psychological and performance problems in varying degrees of magnitude. The research has also demonstrated that although the environment plays a cathartic role, many of these problems are due to interpersonal frictions (Wood, Lugg, Hysong, & Harm, 1999), and affect each individual differently. Consequently, crewmembers often turn to maladaptive behaviors as coping mechanisms, resulting in decreased productivity and psychological discomfort. From this body of research, critical skills have been identified that can help a crewmember better navigate the psychological challenges of long duration space flight. Although most people lack several of these skills, most of them can be learned; thus, a training program can be designed to teach crewmembers effective leadership, teamwork, and self-care strategies that will help minimize the emergence of maladaptive behaviors. Thus, it is the purpose of this report is twofold: 1) To review the training literature to help determine the optimal instructional methods to use in delivering psychological skill training to the U.S. Astronaut Expedition Corps, and 2) To detail the structure and content of the proposed Astronaut Expedition Corps Psychological Training Program.

    Full Text Available The assessment of self-harm risk is a common, difficult, and perplexing task for many physicians, especially those working in emergency departments (ED. Attempts have been made to determine objective methods for assessing patients with suicidal ideation or self-harm though there is still a lack of knowledge about objective assessments of these patients. A study was conducted where 181 suicidal patients were enrolled in two EDs within the city of Edmonton, Canada. Initial interviews were conducted in the ED which collected basic demographics and medical history as well as psychometric measures including the Beck Hopelessness Scale, Barratt Impulsiveness Scale, Brief Symptom Inventory, Drug Abuse Screening Test 10, and CAGE questionnaire. The results of these measures were compared between those who presented to the ED with self-harm and those who presented only with ideation. Those with recent self-harm scored lower on many of the scales and subscales of distress and impulsivity measured compared to those with no recent self-harm. Possible explanations for this difference include differences in psychological traits between the two groups and possible cathartic effects of self-harm. The lower scores obtained by those that present with self-harm may complicate attempts to use psychometric tools to determine future self-harm risk.

    Little is known about the prevalence of encysted Toxoplasma gondii in wild birds. We examined the hearts and breast muscles from 101 raptors for encysted T. gondii. All of the raptors had been submitted for necropsy to the State Veterinary Diagnostic Laboratory, Auburn, Alabama. Tissues were digested in acid-pepsin solution and inoculated into groups of 3-5 laboratory mice. Toxoplasma gondii was isolated from 27 of 101 (26.7%) raptors: 8 of 12 (66.7%) red-shouldered hawks (Buteo lineatus), 13 of 27 (41.1%) red-tailed hawks (Buteo jamaicensis), 1 of 4 (25%) Cooper's hawks (Accipiter cooperi), 1 of 5 (20%) great horned owls (Bubo virginianus), 4 of 15 (26.7%) barred owls (Strix varia), and 1 of 3 (33.3%) kestrels (Falco sparverius). Toxoplasma gondii was not isolated from 3 broad-winged hawks (Buteo platypterus), 3 sharp-shinned hawks (Accipiter striatus), 6 barn owls (Tyto alba), 9 screech owls (Asio otus), a Mississippi kite (Ictinia misisippiensis), 2 golden eagles (Aquila chrysaetos), a bald eagle (Haliaeetus leucocephalus), 4 ospreys (Pandion haliaetus), 4 turkey vultures (Cathartes aura), or 2 black vultures (Coragyps atratus). No significant difference (P > 0.05) in prevalence was detected based on sex using chi-square analysis. Chi-square analysis of the data demonstrated that adult raptors had encysted stages of T. gondii significantly (P < 0.05) more often than did immature raptors. PMID:8277379

    Fire has always been involved in human thoughts, believes and actions. For many psychological reasons fire has been considered as living power: red as the human blood, warm as the human body, clearly shines in the night. Fire worship is very common, especially in regions where terrestrial fire is believed to be the image of the heavenly fire. Fire worship has represented the base for symbolic systems involved in the cultural-anthropological evolution of populations settled close to mount Soratte. Fire cults in this region have originated in independent and long-time separated contexts, according to available knowledge. Hirpi Sorani, ancient inhabitants of mount Soratte territory, celebrated Sorano Apollo by a famous fire walking ceremony, with a likely cathartic and apotropaic meaning, as reported by ancient Roman writers. The victory of Christianity over paganism caused the decline of these religious practices. The beginning of the XIX century witnessed the establishment ofa new kind of devotion to the Virgin Mary at the mount Soratte. Today, this religious piety-linked identity has weakened due to changes in lifestyles,from an agricultural to one based on outside home employment, and has been largely shifted on cultural and anthropological bases. In conclusion, fire worship at mount Soratte has evolved because of external influences and local inhabitants have reacted by asserting their own identity. PMID:25807785

  17. Computer-aided detection in CT colonography: initial clinical experience using a prototype system

    International Nuclear Information System (INIS)

    Computer-aided detection (CAD) algorithms help to detect colonic polyps at CT colonography (CTC). The purpose of this study was to evaluate the accuracy of CAD versus an expert reader in CTC. One hundred forty individuals (67 men, 73 women; mean age, 59 years) underwent screening 64-MDCT colonography after full cathartic bowel cleansing without fecal tagging. One expert reader interpreted supine and prone scans using a 3D workstation with integrated CAD used as ''second reader.'' The system's sensitivity for the detection of polyps, the number of false-positive findings, and its running time were evaluated. Polyps were classified as small (≤5 mm), medium (6-9 mm), and large (≥10 mm). A total of 118 polyps (small, 85; medium, 19; large, 14) were found in 56 patients. CAD detected 72 polyps (61%) with an average of 2.2 false-positives. Sensitivity was 51% (43/85) for small, 90% (17/19) for medium, and 86% (12/14) for large polyps. For all polyps, per-patient sensitivity was 89% (50/56) for the radiologist and 73% (41/56) for CAD. For large and medium polyps, per-patient sensitivity was 100% for the radiologist, and 96% for CAD. In conclusion, CAD shows high sensitivity in the detection of clinically significant polyps with acceptable false-positive rates. (orig.)

    Purpose: the purpose of this multicenter study was to compare a dissection display and an endoluminal display for CT colonography (CTC) by means of detection rates and evaluation time in a screening collective. Materials and methods: 4 blinded readers evaluated CTC datasets from 42 patients with 55 endoscopically confirmed polyps. The datasets were read in a randomized order using two different 3D visualization methods (endoluminal view vs. dissection display; EBW 2.0.1, Philips Medical Systems, Best/NL). Patients underwent cathartic cleansing as well as stool and fluid tagging. All readers except one were experienced in performing CTC. The per-lesion/per-patient sensitivity, per-patient specificity, and evaluation time were calculated. Results: the overall per-lesion sensitivity using the dissection display (and endoluminal view) was 60% (53%) for reader 1, 58% (60%) for reader 2, 67% (71%) for reader 3 and 55% (58%) for reader 4. The per-patient sensitivity using the dissection display (and endoluminal view) was 85% (85%) for reader 1, 80% (85%) for reader 2, 95% (90%) for reader 3 and 80% (80%) for reader 4. The per-patient specificity was 68% with dissection view (77% endoluminal view) for reader 1, 82% (82%) for reader 2, 59% (59%) for reader 3 and 82% (73%) for reader 4. The experienced readers were significantly faster using the perspective-filet view. (orig.)

    Full Text Available This study investigates teacher stress, anxiety, and burnout through my experience teaching music in a suburban Toronto secondary school between 2002 and 2008. Primary data sources include a rich collection of journal entries I have written over a six-year period, which were retrospectively analyzed in this study. Hence, this study is principally rooted in reflective practice. In addition, this study is informed through autobiographical and phenomenological lenses. These other two lenses have allowed me to incorporate secondary source data (anecdotal notes, emails, text messages, and video footage that were repurposed for this study. Findings have exposed two principal thematic representations from the data, namely; (a those that directly or indirectly addressed extracurricular performances, and (b fear of failure. Reexperiencing my experience has been exceedingly therapeutic and cathartic for me, providing insight and transparency into the demanding nature of music pedagogy at the secondary school level. In addition, findings have helped me to refine and develop my current and future pedagogy as a teacher educator.

    Full Text Available Mercury is an element that has been known for at least 4000 years (Chang 1985. It is a metal that is liquid at room temperatures and is widely used in our modern society. Today, the unique chemical and physical properties of mercury are widely used in industry, agriculture, medicine, mining, dentistry and other areas of everyday life. Some of these are used in the manufacture or processing of felt, fireworks, batteries, blackening brass, photography pigments for rubber and plastics, wine colouring and medicine. Medical compounds comprised of 75 % of the list and included antibacterial, antiseptic, topical anaesthetic, immunosuppressant, anti-infective and fungicide, diuretic, cathartic and preservative agents. There are two goals to treatment. First, get rid of the mercury, second, control symptoms so you can be comfortable and productive during the prolonged period when mercury is removed and healing takes place. In order to control the symptoms it is necessary to identify the metabolic defects mercury is causing for you.

    Barbaloin is C-glucoside of aloe emodin anthrone which is found in the plant name as Aloevera is a perennial succulent (Liliaceal), also called the healing plant. Barbaloin have variety of pharmacological activity such as strong inhibitory effect on histamine release, anti-inflammatory, cathartic, antiviral, antimicrobial, anticancer, antioxidant activity and alternative for pharmaceutical or cosmetic applications. The peak amount of barbaloin was reached about 3 h after oral administration. Concentration of barbaloin in Aloe vera leaves was shown to depend on the leaf part, age, and position of the leaf. Young leaves contain more barbaloin compared to old one. Various researches have been done on barbaloin but still the relationship between the barbaloin and its overall effect has not been clarified. A more specific perceptive of the pharmacological activities of barbaloin is required to develop for pharmaceutical purpose. Many attempts have been made regarding its isolation, biological activity to examine their effects, and clarify their functional mechanism. This review gives a brief idea about its uses, ethnomedicinally and commercially important analytical techniques and their pharmacological activities.

    Ancient Greek physicians believed that health resulted from a balance of natural forces. Many, including Dioscorides, made compilations of plants and medicines derived from them, giving prominence to diuretics, cathartics and emetics. During the Roman Empire, although Greek physicians were highly valued, the Roman matron performed many medical functions and magic and astrology were increasingly used. In Judaic and later Christian societies disease was equated with divine disfavor. After the fall of Rome, the classical Greek medical texts were mainly preserved in Latin translation by the Benedictine monasteries, which were based around a patient infirmary, a herb garden and a library. Local plants were often substituted for the classical ones, however, and the compilations became confused and inaccurate. Greek medicine survived better in the remains of the Eastern Roman Empire, and benefitted from the influence of Arab medicine. Intellectual revival, when it came to Europe, did so on the fringes of the Moslem world, and Montpellier and Salerno were among the first of the new medical centers. Rather than relying on ancient experts, the new experimental method reported the tested effects of substances from identified plants. This advance was fostered by the foundation of universities and greatly aided by the later invention of the printing press, which also allowed wider dissemination of the classical texts.

    This article explores the feasibility of running "PremieStart," a nine-individual-session maternal-premature infant interaction program, within a neonatal unit (NNU) in England. Four mothers of premature infants completed seven sessions on the NNU and two at home. Mothers and NNU staff provided feedback on PremieStart. Measures of maternal-infant relationship, maternal well-being, and maternal reflective functioning were completed before and after intervention. Thematic analysis of mothers' feedback highlighted the emotional, but cathartic, experience of engaging with PremieStart. NNU staff feedback indicated the need to include them more in PremieStart. Both mothers and staff were supportive of future implementation of PremieStart and highlighted the ongoing need for psychological support on the NNU. PremieStart was implemented with positive feedback from mothers and staff, with support shown for the continued use of PremieStart in the NNU. However, for future implementation, the self-report outcome measures need reviewing, and more involvement of fathers and NNU staff is needed. In addition, a larger sample with a control group should be utilized. PMID:27348583

    Observed at z = 4.601 and with {L}{{bol}} = 3.5 × {10}14 {L}⊙ , W2246-0526 is the most luminous galaxy known in the universe and hosts a deeply buried active galactic nucleus (AGN)/supermassive black hole (SMBH). Discovered using the Wide-field Infrared Survey Explorer, W2246-0526 is classified as a hot dust-obscured galaxy, based on its luminosity and dust temperature. Here, we present spatially resolved ALMA [C ii]157.7 μm observations of W2246-0526, providing unique insight into the kinematics of its interstellar medium (ISM). The measured [C ii] -to-far-infrared ratio is ˜ 2 × {10}-4, implying ISM conditions that compare only with the most obscured, compact starbursts and AGNs in the local universe today. The spatially resolved [C ii] line is strikingly uniform and very broad, 500-600 km s-1 wide, extending throughout the entire galaxy over about 2.5 kpc, with modest shear. Such a large, homogeneous velocity dispersion indicates a highly turbulent medium. W2246-0526 is unstable in terms of the energy and momentum that are being injected into the ISM, strongly suggesting that the gas is being blown away from the system isotropically, likely reflecting a cathartic state on its road to becoming an unobscured quasar. W2246-0526 provides an extraordinary laboratory to study and model the properties and kinematics of gas in an extreme environment under strong feedback, at a time when the universe was 1/10 of its current age: a system pushing the limits that can be reached during galaxy formation.

    Full Text Available Background: South Africa is on the brink of another wave of major health system reforms that underscore the centrality of primary health care (PHC. Nursing managers will play a critical role in these reforms. Objective: The aim of the study was to explore the work experiences of PHC clinic nursing managers through the use of reflective diaries, a method hitherto under-utilised in health systems research in low- and middle-income countries. Design: During 2012, a sub-set of 22 PHC nursing managers was selected randomly from a larger nurses’ survey in two South African provinces. After informed consent, participants were requested to keep individual diaries for a period of 6 weeks, using a clear set of diary entry guidelines. Reminders consisted of weekly short message service reminders and telephone calls. Diary entries were analysed using thematic content analysis. A diary feedback meeting was held with all the participants to validate the findings. Results: Fifteen diaries were received, representing a 68% response rate. The majority of respondents (14/15 were female, each with between 5 and 15 years of nursing experience. Most participants made their diary entries at home. Diaries proved to be cathartic for individual nursing managers. Although inter-related and not mutually exclusive, the main themes that emerged from the diary analysis were health system deficiencies; human resource challenges; unsupportive management environment; leadership and governance; and the emotional impact of clinic management. Conclusions: Diaries are an innovative method of capturing the work experiences of managers at the PHC level, as they allow for confidentiality and anonymity, often not possible with other qualitative research methods. The expressed concerns of nursing managers must be addressed to ensure the success of South Africa's health sector reforms, particularly at the PHC level.

  8. CharlesTaylor, phronesis, and medicine: ethics and interpretation in illness narrative.

    2011-08-01

    This paper provides a brief overview and critique of the dominant objectivist understanding and use of illness narrative in Enlightenment (scientific) medicine and ethics, as well as several revisionist accounts, which reflect the evolution of this approach. In light of certain limitations and difficulties endemic in the objectivist understanding of illness narrative, an alternative phronesis approach to medical ethics influenced by Charles Taylor's account of the interpretive nature of human agency and language is examined. To this end, the account of interpretive medical responsibility previously described by Schultz and Carnevale as "clinical phronesis" (based upon Taylor's notion of "strong" or "radical evaluation") is reviewed and expanded. The thesis of this paper is that illness narrative has the ability to benefit patients as well as the potential to cause harm or iatrogenic effects. This benefit or harm is contingent upon how the story is told and understood. Consequently, these tales are not simply "nice stories," cathartic gestures, or mere supplements to scientific procedures and decision making, as suggested by the objectivist approach. Rather, they open the agent to meanings that provide a context for explanation and evaluation of illness episodes and therapeutic activities. This understanding provides indicators (guides) for right action. Hence, medical responsibility as clinical phronesis involves, first, the patient and provider's coformulation and cointerpretation of what is going on in the patient's illness narrative, and second, the patient and provider's response to interpretation of the facts of illness and what they signify-not simply a response to the brute facts of illness, alone. The appeal to medical responsibility as clinical phronesis thus underscores the importance of getting the patient's story of illness right. It is anticipated that further elaboration concerning the idea of clinical phronesis as interpretive illness narrative will

    2010-08-01

    Full Text Available The article presents and discusses the custom of kynomartyrion (dogtorture which took place in the Greek lands until the 1980s. In many areas it stopped in the 1930s because of its cruelty. The author begins his discussion with the presentation of some elements that are related to the dog. More specifically, the dog is an animal that entered the humanized environment long ago and belongs to the creatures whose nature is twofold because it is part of thehuman and the non-human worlds and it has been treated as twofold by at least the Indo-Europeans. It is also maintained that the liminal Hellenistic period was decisive for the formation of folk worship because of the religious syncretism and the invasion of demons that dominated in the Eastern Mediterranean. The author points out its remarkable similarities to ancient Greek and Roman (and Indo-European fertile, cathartic and other sacrificial practices. Due to industrialization of agriculture and rationalization of the magical way of thought of the “traditional” peasant, performance of the custom was transformed into a folkloric, spectacular one with intensely violent and sadistic behaviour on the part of humans in the places where it still took place after 1960. The writer argues that violence was always an inherent characteristic of the custom. Nonetheless, the archaic, and later folk thinking ritualized the performance and attributed to it a different facet, devoid of any sacred elements, during the 20th century where its inherent violence was manifested in its raw essence.

    Purpose: To evaluate the feasibility and sensitivity of the 3D-reading of fecal-tagging CT colonography (CTC) with a novel structure-analysis electronic cleansing (SAEC) in detecting colorectal flat lesions in comparison with a cleansed 3D reading with Viatronix V3D Colon system (V3D) and primary uncleansed 2D reading (2D). Materials and methods: Forty CTC cases with flat lesions were retrospectively observed. The Subjects from a multicenter clinical trial underwent cathartic bowel preparation with orally administrated barium-based fecal-tagging. Sixty-nine flat lesions were confirmed using colonoscopy and histopathology as a reference standard. The results from SAEC reading were compared with those of prospective V3D and 2D readings. Results: Overall detection sensitivity with SAEC was 52% (36/69), which was statistically higher than that of 32% (22/69) and 29% (20/69) with V3D and 2D readings, respectively (p < 0.05). The sensitivities in detecting not-on-fold flat lesions were 63% (24/38), 45% (17/38), and 42% (16/38) with SAEC, V3D, and 2D readings, respectively; whereas those of on-fold flat lesions were 39% (12/31), 16% (5/31), and 13% (4/31), respectively. None of the eight flat lesions (2-9 mm) at cecum was detected by any of the three reading methods. Excluding the flat lesions at cecum, the sensitivity with SAEC for detecting flat lesion {>=}4 mm increased to 84% (31/37). Conclusions: The fecal-tagging CTC with structure-analysis electronic cleansing could yield a high sensitivity for detecting flat lesions {>=}4 mm. The not-on-fold flat lesions were detected with higher sensitivity than on-fold flat lesions.

    Qing li shan jiu fang (Formulary for Effective Rescuing in the Qingli Reign), compiled by Hanlin Academy of Medical Official in 1048 under the decree of the Emperor, is a medical formulary exclusively used to prevent and control poisonous parasite disease. It is composed of formulae provided by a medical scholar of Fuzhou, Lin Shiyuan, together with other formulae collected by the imperial physicians and so on. Unfortunately, it was lost about after the demise of the Southern Song Dynasty. However, in the Southern Song Dynasty, two books, Liang Kejia's Chun xi san shan zhi and Hong Mai's Yi jian zhi bu, do record the progress of its compilation, parts of its contents and the condition of its spread and application. Moreover, they also describe the kinds, the feature, the epidemic, prevention and cure of parasite poison. It is especially good that this book preserves three famous formulae, including Zhi gu du zheng fang (Orthodox Formula for Treating Parasitic Poisons) (called A Cathartic Formula with 8 Ingredients in the Yuan Dynasty), Jie du wan (Antidote Pills) and He qi tang san (Powder of Decoction for Harmonious Qi), which are of medical significance for the understanding of the property of Qing li shan jiu fang. The Song emperors, the central government and local officials all paid high attention to the spread and application of this book. They not only enacted it to the counties, and provinces, but also carved it on stone steles for popularizing the knowledge of preventing parasitic poisons to medical workers and common people.

    The number of wind farms operating in the Isthmus of Tehuantepec, southern Mexico, has rapidly increased in recent years; yet, this region serves as a major migration route for various soaring birds, including Turkey Vultures (Cathartes aura) and Swainson's Hawks (Buteo swainsoni). We analyzed the flight trajectories of soaring migrant birds passing the La Venta II wind farm during the two migratory seasons of 2011, to determine whether an avoidance pattern existed or not. We recorded three polar coordinates for the flight path of migrating soaring birds that were detected using marine radar, plotted the flight trajectories and estimated the number of trajectories that intersected the polygon defined by the wind turbines of La Venta II. Finally, we estimated the actual number of intersections per kilometer and compared this value with the null distributions obtained by running 10,000 simulations of our datasets. The observed number of intersections per kilometer fell within or beyond the lower end of the null distributions in the five models proposed for the fall season and in three of the four models proposed for the spring season. Flight trajectories had a non-random distribution around La Venta II, suggesting a strong avoidance pattern during fall and a possible avoidance pattern during spring. We suggest that a nearby ridgeline plays an important role in this pattern, an issue that may be incorporated into strategies to minimize the potential negative impacts of future wind farms on soaring birds. Studies evaluating these issues in the Isthmus of Tehuantepec have not been previously published; hence this work contributes important baseline information about the movement patterns of soaring birds and its relationship to wind farms in the region.

    Full Text Available The focus of this work is the operation of visual and audio signs in an urban ambience of entertainment, particularly the arragement of the interpretant of these signs in the luminous and cathartic output of vídeo presentations. The semiotic concept of diagrammatic reasoning is used to describe and analyze the apparitions of a clown character in an electronic music show of the British duo The Chemical Brothers, selected corpus for the study. The analyses cover the uses and the track of images and sounds at the moment the action takes place, with mask and trance being mobilized to exert hedonist, phantasmagoric, carnivalesque and ritualistic influence on the audience. The acting clown tends to produce interpretants, initially of na emotional and, subsequently, of an energetic nature, so as to incisively establish identity links with the audience. The developments of the character’s apparitions (which is inserted into the performance in different ways to yield persuasive messages are analyzed along with the effects resulting from the conjunction between sound and image which propagates in a synchronic, ambivalent and profuse manner, amid a crowd, an urban landscape and a playful phenomenon. A spiral shape guide was prepared to support the analysis and enable to infer about the work of the interpretant signs from the VJing, a kind of semeiosis typical of the videojockey’s action in this sort of event. Identity is then impregnated and so are mnemonic effects on the metropolitan cultures and habits, in the libertarian and effervescent nature of the party, on the emotion fruition reached by the audience.

    The importance of olfaction for various avian behaviors has become increasingly evident. So far, the use of olfaction for food detection among raptors has only been demonstrated for Cathartes vultures. The Oriental honey buzzard (Pernis orientalis) is a resident and migrant in Taiwan and regularly forages in apiaries. One of its foods in apiaries is yellow pollen dough, a softball-sized mixture of pollen, soybeans, and sugar that beekeepers provide as a supplementary food for bees. Given that pollen dough is not similar to any naturally occurring food, we hypothesized that buzzards identify the dough’s nutritious contents using olfaction, perhaps in combination with vision. Using a series of choice experiments in which individuals could choose between two doughs, we showed that (1) buzzards almost unerringly chose pollen-containing over pollen lacking doughs when otherwise the doughs were identical in size, shape, and yellow color; (2) buzzards always preferred yellow over black or green doughs if both doughs contained pollen; (3) buzzards still preferred pollen-containing over pollen-lacking doughs when both doughs were black, but at a lower rate than in (1). We statistically excluded the possible influences of the doughs’ relative brightness or of repeat visits by the same individuals. Our experiments thus suggest the use of a ‘multi-modal foraging strategy’ among buzzards whereby olfaction and vision are likely to be both used in identifying food at close distances. We also estimated the olfactory receptor gene repertoire size in the buzzard’s genome which is almost five times as large as that of three other raptor species. Therefore, olfaction is likely of far greater ecological importance to this species than to other raptor species. We suggest that olfaction should be considered in the design of behavioral and genetic studies to better understand the use of multiple senses in avian behaviors. PMID:26177533

Sustentado teoricamente em, basicamente, três autores: Marx, Gramsci e Vázquez, o texto inicia apresentando alguns apontamentos sobre o conceito de práxis e sobre o de "catarsis", para posteriormente identificar a educação como um processo práxico e catártico. Essa compreensão da educação, que resgata os conceitos de "práxis comunitária" e "práxis social", resulta em dupla asserção conclusiva, a saber: primeiro, que todo processo educativo resulta em alguma transformação e, segundo, que nem toda transformação resultante da educação é capaz de alterar as estruturas e superestruturas que caracterizam a totalidade da vida social.This article refers to the evaluation of educational activities developed by NGO's, trade unions and political parties, which are understood as praxis capable of generating "catharsis" of different types. Referenced in basically three authors: Marx, Gramsci and Vázquez, the text begins by presenting some remarks on the concept of praxis and "catharsis", identifying afterwards education as a process at the same praxic and cathartic. This understanding of education, which recalls the concepts of "community praxis" and "social praxis", resulting in a double conclusive assertion, namely: first that the entire educational process results in some change, and second, that not all resulting transformation of education is able to change the structures and superstructures that characterize all social life.

    Full Text Available The recent polemics about the reconstruction of the ancient Roman theatre in Sagunto (Valencia, done by the Italian architect Giorgio Grassi in collaboration with the Spanish architect Manuel Portaceli, could have been an enriching debate on the criteria of intervention on the monuments, had it not been frustrated by the virulence and the schematic nature of the argumentations used for and against the work. On the other hand, in the opinion of the author of this article, the serious methodological deficiencies (especially with regard to previous historical research and its relation with the project, as well as the poorness of the new architecture designed by Grassi, invalidate the work of Sagunto as a paradigm of one particular restoration style (the harmonious diachrony. For this reason, the work will remain only as another example of the Spanish disorder in the eighties. The author believes, however, in the healthy cathartic role which the work and the polemics may have had since they made it clear before the public opinion that there is a need for the historians and architects to finally face their authentic commitments in monument restoration.

  19. Impact of gamma radiations on phytochemistry of senna, Cassia angustifolia Vahl

    International Nuclear Information System (INIS)

    Cassia angustifolia (senna) is native to India, and is cultivated mainly in India and Pakistan. The parts of this plant used medicinally are the leaves Senna is also known by the names Alexandrian Senna and and the pods. The leaves have a purging quality, but afterwards may have a binding effect. Both the leaves and pods are used in many over-the-counter pharmaceutical laxative preparations. People in northern Africa and southwestern Asia have used Senna as a natural laxative for centuries. Senna is a powerful cathartic used primarily in the treatment of constipation, working through a stimulation of intestinal peristalsis. The primary chemical Constituents of Senna include anthraquinone glycosides (sennosides, aloe-emodin, rhein), beta-sitosterol, flavones, tartaric acid, mucin, essential oil, mucilage, tannin and resin. The sennosides are irritating to the large intestine lining, causing peristaltic action and bowel evacuation. Senna is often combined with aromatic, carminative herbs such as cardamom, ginger root, peppermint and fennel to increase its palatability. Other historical applications of this herb have included support for inflammatory skin conditions, hypertension and weight control. Although the biological effects of large doses of ionizing radiation are predominantly harmful, low-to-intermediate doses have been observed to enhance growth and survival, augment the immune response, and increase resistance to the mutagenic and clastogenic effects of further irradiation in plants, bacteria, insects, and mammals. The existence of these stimulatory, or adaptive responses implies that the dose-response relationships for genetic and carcinogenic effects of radiation may be similarly biphasic or hermetic in nature. The leaflets of this plant constitute the principal raw material, is an excellent source of sennosides. To investigate the effect of mutagenic treatments on phytochemical characteristics, the dry seeds of senna were treated with different doses of

    Background Recent years have seen an exponential increase in people with long-term conditions using the Internet for information and support. Prior research has examined support for long-term condition self-management through the provision of illness, everyday, and emotional work in the context of traditional offline communities. However, less is known about how communities hosted in digital spaces contribute through the creation of social ties and the mobilization of an online illness “workforce.” Objective The aim was to understand the negotiation of long-term condition illness work in patient online communities and how such work may assist the self-management of long-term conditions in daily life. Methods A systematic search of qualitative papers was undertaken using various online databases for articles published since 2004. A total of 21 papers met the inclusion criteria of using qualitative methods and examined the use of peer-led online communities for those with a long-term condition. A qualitative meta-synthesis was undertaken and the review followed a line of argument synthesis. Results The main themes identified in relation to the negotiation of self-management support were (1) redressing offline experiential information and knowledge deficits, (2) the influence of modeling and learning behaviors from others on self-management, (3) engagement that validates illness and negates offline frustrations, (4) tie formation and community building, (5) narrative expression and cathartic release, and (6) dissociative anonymity and invisibility. These translated into a line of argument synthesis in which four network mechanisms for self-management support in patient online communities were identified. These were (1) collective knowledge and identification through lived experience; (2) support, information, and engagement through readily accessible gifting relationships; (3) sociability that extends beyond illness; and (4) online disinhibition as a facilitator

    Full Text Available Harvest time has been since Upper Antiquity an exceptional occasion in peasant societies, giving rise to festive customs such as duels of improvised poetry in obscene tone and motif. In these duels, precepts of decency were momentarily removed. The historical and comparative research since the fescennini verses of Antiquity, through the pullas of the trovadores de repente of the Golden Age and other satirical genres, allows to link the priapic improvised poetry of the Alpujarra in both reaping and grape harvest contexts to a long popular tradition in which debates of burlesque verses were an entertainment associated with the nexus between fertility of earth and sexuality and with a sense of regeneration that has cathartic laugh. The survival of this burlesque and erotic register among the Alpujarra troubadours in certain festivals, coincidental in dates, spaces and actors with the traditional context of licenses during harvest time, suggests the reusing of these duels of inventiveness, in which participants play recalling a time when

    Las cosechas han constituido desde antiguo un momento excepcional en las culturas campesinas y han propiciado costumbres festivas, como las luchas de poesías improvisadas de tono y temática obscena, en que se levantaba efímeramente el precepto del decoro. El rastreo histórico y comparativo desde los versos fesceninos de la Antigüedad, pasando por las pullas de los trovadores de repente en el Siglo de Oro y otros géneros satíricos, permite vincular el trovo priápico de la Alpujarra en contextos de siega, parva y vendimia, a una larga tradición popular en que las porfías de versos burlescos constituían un divertimento asociado al nexo de unión entre la fertilidad de la tierra y la sexualidad, así como al sentido regenerador de la risa catártica. La pervivencia en el trovo alpujarreño de este registro burlón y lúbrico en ciertas fiestas coincidentes en fechas

    Ingestion of household products and plants are the leading cause for calls to the poison control centres as far as children are involved. Severe intoxication in children has become infrequent due to childproofed package and blister packs for drugs. Chemical accidents in adults give rise to hospital admission in only 5 %. Suicidal selfpoisonings are still a challenge for paramedics, emergency and hospital doctors. Natural toxins as amatoxins, cholchicine and snakebites can lead to severe intoxication. Sedatives, antidepressants and analgesics are the drugs which are often used for suicidal intent due to their availability. Quetiapine and paracetamol are the drugs which are ingested for attempted suicide/ suicide mostly. The treatment of poisoning centers on the severity which can be judged by the poison severity score, the Reed classification or the GCS.Most intoxicated patients can be treated symptomatically or by intensive care measurements. Antidotal treatment however is needed for some specific poisonings.Exact sample drawing is essential for diagnostic and forensic purposes. There is no evidence based proof for the effectiveness of primary detoxification from the gastrointestinal tract like forced emesis, gastric lavage or the use of cathartics. Early after the ingestion of a harmful substance the administration of activated charcoal seems advisable. Hemodialysis can remove water soluble substances with a small volume of distribution. Multiple charcoal administration may exhibit some influence on secondary detoxification. Provision of evidence of the efficacy for newer antidotes like hydroxocobalamin in smoke inhalation, fomepizol for toxic alcohols and silibinin for amanita poisoning are emerging. Two recently recommended therapeutic principles have still to demonstrate their ability: Firstly the treatment of patients with calcium receptor antagonistic and beta-receptor antagonistic agents poisoning by high dose of insulin plus glucose, secondly the

    levels in urine. Remedies include elimination of lead in the environment, changes in children's behavior and dietary checks for adequate calcium and iron intake. Chelation therapy, using Ca edetate and succimer eliminates lead from the skeleton, which is then quickly excleted using a cathartic to help prevent re-absorption. Chelation may save lives where BLLs are very high. There is usually a short term reduction of BLLs with a subsequent rise. Serious cases may require repeat therapies. Chelation should be considered in children with BLLs > or = 45 µg/dl. Chelation therapy reduces BLLs and associated symptoms. However cognitive decline may be irreversible, indicating that emphasis should be on prevention rather than cure.

    characterized as outcasts. From Pecola, the alienated victim of the WASP definition of beauty to Consolata, the “revised Reverend Mother,” Morrison’s fiction appears to weave its way through the moral complexities of African American female resistance to white male rule—theologically based on the canonical reading of the Fall as supreme calamity caused by Eve, the arch-temptress and sinner—to hand authority back to the pariah and wrongdoer: the black woman. However, far from boiling down to this deconstructive strategy, Morrison’s fiction seems to oppose religious doctrine only so as to sound the ontological depth of Christianity: while challenging the theological basis of sexist and racist assumptions, Morrison poses as an authoritative spiritual force able to craft her own Gospel of Self, based on cathartic moments of revelation where mostly female characters experience a mystic sense of connectedness to self and other, time and place. An African American female variation on the New Testament’s “Kingdom within,” Morrison’s novels echo black abolitionist Sojourner Truth’s famous speech “Ain’t I a Woman?” and its call for theological revision and gender emancipation.

    interconnectedness of narrative and theater, the cohabitation of story and performance, and the relationship between “telling” and “seeing”. What lends the third Diabolique its importance in terms of theatricality is the reliance of its plot on the interplay of theater, without which, in the final analysis, the narrative would not exist. Indeed, the originality of the story resides in its association to a theatrical representation. It follows that, in a fictional work, the act of narration is guaranteed by virtue of the existence of fiction. In other words, the story is possible only in so far as it dramatizes itself. This means that what the narrative represents draws its strategy from what is represented. The article will examine the peculiar relationship established between narration and theater and will attempt to shed light on the resulting implications of this relationship. If, thanks to its theatrical nature, the novella’s plot hints at more than it presumes to reveal through the succession of its events, it is that the narration appears to adopt as its objective the denunciation of realist fiction as ineffectual, while upholding the exemplary moral nature to which conforms the poetics of tragedy. Yet, does not the cathartic release through reading, as enunciated in the preface of Diaboliques and suggested by the intense theatralization of the story, find itself contradicted by a denouement that outwardly sabotages the very principles of tragedy?

    Full Text Available BACKGROUND: The cleansing of the colon for a colonoscopy exam must be complete so as to allow the visualization and inspection of the intestinal lumen. The ideal cleansing agent should be easily administered, have a low cost, and minimum collateral effects. Sodium picosulfate together with the magnesium citrate is a cathartic stimulant and mannitol is an osmotic laxative, both usually used for this purpose. AIMS: Assess the colon cleanliness comparing the use of mannitol and sodium picosulfate as well as evaluate the level of patient satisfaction, the presence of foam, pain, and abdominal distension in hospitalized patients undergoing colonoscopy. METHODS: A prospective, randomized, single-blind study with 80 patients that compared two groups: mannitol (40 and sodium picosulfate (40. Both groups received the same dietary orientation. The study was approved by the hospital’s Ethics and Research Committee. The endoscopist was blind to the type of preparation. Outcomes evaluated: level of the colon’s cleanliness, patient’s satisfaction, the presence of foam, abdominal pain and distension, and the duration of the exam. The data was analyzed by means of the chi-squared test for proportions and Mann-Whitney for independent samples. RESULTS: There were no statistically significant differences between the groups in relation to the level of the colon’s cleanliness, patient’s satisfaction, the presence of foam, abdominal pain, and the duration of the exam. Fifteen percent of the exams of the mannitol group were interrupted while from the sodium picosulfate group it was 5%. The presence of foam was similar for both groups. The average duration for carrying out the exam was 28.44 minutes for the mannitol group and 35.59 minutes for the sodium picosulfate group. Abdominal distension was more frequent in the mannitol group. If they would have to do the same exam, the answer was that 80% said yes from the mannitol group and 92.5% from the sodium
