The Zone-tailed Hawk (Buteo albonotatus) might well be dubbed "the Great Pretender" because it so closely resembles the ubiquitous Turkey Vulture (Cathartes aura) in appearance and behavior as to be frequently mistaken for it. In the border regions where it lives, it may be confused as well with another "Mexican" raptor, the Common Black-Hawk (...

The aim of this study was to develop a method of removing sennoside to reduce the cathartic effect of rhubarb while conserving its other pharmacological activities. Rhubarb powder was steam autoclaved at 121°C and 0.14 MPa for 20, 60, or 120 minutes, and HPLC analysis was conducted to determine levels of rhubarb components. Mice were fed non-autoclaved or 20-minute-autoclaved rhubarb extracts. Feces were collected and weighed over a 24-hour period. India ink was orally administered to determine the distance of fecal migration through the intestinal tract. Autoclaving 20, 60, and 120 minutes decreased sennoside A and B to trace levels but only autoclaving 20 minutes conserved most of the (+)-catechin, (-)-epicatechin, and (-)-epicatechin gallate contents (i.e., 69%, 90%, 88%, respectively). Therefore only rhubarb autoclaved for 20 minutes was used in subsequent experiments. Fecal output (in g) in mice treated with water (control), autoclaved rhubarb, and non-autoclaved rhubarb was 2.78 ± 0.07, 3.30 ± 0.13 (p = 0.348), and 3.81 ± 0.07 (p = 0.005). India ink migration was far less in mice treated with autoclaved rhubarb vs non-autoclaved rhubarb. Steam autoclaving the rhubarb for 20 minutes reduces sennoside levels and its cathartic activity while conserving its other pharmacological activities.

Due to their natural origin, apparent low oral toxicity, effectiveness, and accessibility without a medical prescription, the anthranoid laxatives are a popular remedy for constipation and are frequently used abusively. Therefore, it is important to characterize its harmful and/or toxic effects. The sennosides, main active metabolites of senna, exhibit a very low toxicity in rats, and its genotoxic activity in bacterial strains as well as mammal cells was classified as weak in those cases where it was shown to be significant. The toxicological and mutagenic status of the crude extract of senna, however, is not as well characterized, and it is necessary to do so since it is frequently, and at the same time incorrectly, believed that the chronic use of anthranoid laxatives is a risk factor for the development of colorectal cancer. The objective of this article was to review the information that arises in various scientific medical databases using key words such as senna, sen, Senna alexandrina, Cassia angustifolia, sennosides, laxative toxicity, mainly S and non-S articles of journals with an editorial committee. Web pages of products or companies that publicize or commercialize this type of laxative were not included. This analysis establishes that (1) there is no convincing evidence that the chronic use of senna has, as a consequence, a structural and/or functional alteration of the enteric nerves or the smooth intestinal muscle, (2) there is no relation between long-term administration of a senna extract and the appearance of gastrointestinal tumors or any other type in rats, (3) senna is not carcinogenic in rats even after a two-year daily dose of up to 300 mg/kg/day, and (4) the current evidence does not show that there is a genotoxic risk for patients who take laxatives containing senna extracts or sennosides.

Full Text Available A clinical case of Louis Vivet, described by Bourru and Burot (1888, contributed to elaborate the concepts of multiple personality and cathartic method. The authors present this clinical case, the cultural context of this mental illness, and the relevant theories. The genetic analysis of Louis Vivet's iatrogenic disorder or transient mental illness (Hacking, 2002 shows how the dominant theories on identity and memory contributed to construct the symptoms observed by Bourru and Burot (1888 and validated the therapeutic methods.

Inciting and etiologic agents of colitis.

Silva, J; Fekety, R; Werk, C; Ebright, J; Cudmore, M; Batts, D; Syrjamaki, C; Lukens, J

1984-01-01

Since 1979, 3,115 stool samples were tested for detection of Clostridium difficile and its cytotoxin; these were obtained from patients who had drug-related diarrhea. Presumed or proven colitis due to C. difficile was diagnosed in 130 patients. Drugs implicated most commonly as causing or associated with the onset of enterocolitis due to C. difficile were ampicillin (38 episodes), cephalosporins (71), clindamycin (36), and the aminoglycosides (45). The hamster model of colitis was employed to explore the role of other inducing agents. Altering the usual diet of hamsters to one with a higher protein content decreased the time to death due to C. difficile cecitis following the administration of cefazolin (10 mg). Several cathartics also were studied for their effect on the lethality of antibiotic-induced cecitis. Daily administrations of castor oil (0.5 ml per day) and vegetable oil (1.0 ml per day) improved survival against lethal doses of clindamycin. Milk of magnesia or mineral oil provided no protection. Four patients with C. difficile colitis induced by therapy with cytotoxic drugs also were identified. Methotrexate induced cecitis when administered orally and daily to hamsters, and C. difficile and its cytotoxin were identified in the hamsters' stools. Death due to methotrexate-induced cecitis was prevented by daily administration of folinic acid or vancomycin. These data demonstrate that a variety of antibiotics, antineoplastic agents, cathartics, and diet changes can induce C. difficile colitis in humans and hamsters.

Storytelling: an approach that can help to develop resilience.

Science.gov (United States)

East, Leah; Jackson, Debra; O'Brien, Louise; Peters, Kathleen

2010-01-01

Stories convey values and emotions, and can reveal the differences and similarities between people's experiences. Elucidating personal stories involves sharing which can help form bonds and supportive networks. With reflection, these can help to develop resilience. While the literature recognises the potential cathartic and therapeutic benefits associated with storytelling in research, links between the development of personal resilience and storytelling for research purposes have not been drawn. This paper argues that storytelling aids the development of personal resilience and provides opportunities to celebrate the hardiness of research participants who contribute to knowledge by recounting their stories of difficulty and adversity.

Finding the Hole in the Wreck: Shamanic practice in the Poetry of Adrienne Rich and Anne Sexton

In this paper I draw a concrete line from shamanism to confessional poetry. I’m interested in looking at how the cathartic function of confessional writing is even stronger when passed through the traditional shamanic hole that leads to experiencing the underworld of the unconscious. I want...... to argue that both Adrienne Rich and Anne Sexton manipulate with visualization techniques in their symbolic imagery in order to create an atmosphere that is akin to a shamanic journey. The poetic examples that I want to discuss demonstrate how the “language of the suicides” (Sexton) and “the thing itself...

Turkey vulture surveys in Cuba

Wotzkow, C.; Wiley, J.W.

1988-01-01

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.

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

International Nuclear Information System (INIS)

Linguraru, Marius George; Panjwani, Neil; Fletcher, Joel G.; Summer, Ronald M.

2011-01-01

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%.

The voices of neurosurgeons: doctors' non-medical writing.

Science.gov (United States)

Bernstein, Mark

2007-05-01

Biomedical publishing is an integral part of medicine--both to those who produce it and those who consume it to improve the care of their patients. Non-medical writing by surgeons usually takes the form of creative non-fiction, generally reflective essays on moving and emotionally charged situations such as working in the trenches in war-time or in natural disasters, or dealing with individual patients. Such writing is both creative and cathartic for neurosurgeons, and can help educate patients thus improving the doctor-patient relationship. The purpose of this article is to encourage fellow neurosurgeons to pursue this enjoyable and valuable endeavour, to utter a call to arms so to speak.

We have limited resources available for the treatment and prevention of violent behavior. The usefulness of the most commonly used medications, namely the selective serotonin-reuptake inhibitor [SSRI] agents for the above purpose is a debated issue in the psychiatric literature. The aim of this case report is to add an ethnopharmacological perspective to the management of human aggression. Particularly, attention is called to the potential prosocial effect of the Amazonian beverage, ayahuasca--a decoctum, which has been used traditionally for multiple medico-religious purposes by numerous indigenous groups of the Upper Amazon--and has been found to be useful in crisis intervention, achieving redemption, as well as eliciting cathartic feelings with moral content.

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

International Nuclear Information System (INIS)

Cohen, N.; Antonelli, R.; LoSasso, T.

1977-01-01

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

La interpretación intelectualista de la tragedia: Una discusión critica

Directory of Open Access Journals (Sweden)

Carmen Trueba

2013-11-01

Full Text Available The nature of tragedy is a matter of controversy. The intelectualist vision of tragedy has gained ground in the last years. In this paper I intend to discuss on the heterodox and extreme version of the cognitivism, defended recently by Pierluigi Donini in La tragedia, senza la catarsi, which firmly rules out the emotional or cathartic function of tragic drama and asserts that “the function of tragedy is not catharsis, but its crowning or last stage: understanding”. The revision of the arguments stated by Donini will allow to enlighten some obscure points in the aristotelian theory of tragedy, particularly the place of music and entertainment in tragic drama.

Maintenance of syntenic groups between Cathartidae and Gallus gallus indicates symplesiomorphic karyotypes in new world vultures

Marcella M. Tagliarini

2011-01-01

Full Text Available Similarities between New World and Old World vultures have been interpreted to reflect a close relationship and to suggest the inclusion of both in Accipitridae (Falconiformes. However, deeper analyses indicated that the placement of the New World vultures (cathartids in this Order is uncertain. Chromosome analysis has shown that cathartids retained a karyotype similar to the putative avian ancestor. In order to verify the occurrence of intrachromosomal rearrangements in cathartids, we hybridized whole chromosome probes of two species (Gallus gallus and Leucopternis albicollis onto metaphases of Cathartes aura. The results showed that not only were the syntenic groups conserved between Gallus and C. aura, but probably also the general gene order, suggesting that New World vultures share chromosomal symplesiomorphies with most bird lineages.

["I swear on Apollus Medicus...": the birth of medical deontology].

Ceccobelli, Sandro

2011-01-01

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.

We are anxious for investigation of new chemicals which are able to eliminate the intraluminal gas by liquefaction, in a similar way of which gas foaming agent make the gas by gasification

Comparison of eye morphology and retinal topography in two species of new world vultures (Aves: Cathartidae)

Lisney, Thomas J.; Stecyk, Karyn; Kolominsky, Jeffrey

2013-01-01

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 overall retinal topography, the total number of cells in the retinal ganglion cell layer, peak and average cell densities, cell soma area frequency distributions, and the theoretical peak anatomical spatial resolving power were the same in both species. This suggests that the visual systems of these two...

[Humanities as a means of survival: the testimony of a Siberian prisoner of war in the First World War].

Inić, Suzana; Fatović-Ferenčić, Stella; Kujundžić, Nikola

2015-11-01

This article looks into the autobiography of the Croatian chemist and pharmacognosist Antun Vrgoč (1881-1949) entitled My Memories of the World War 1914-1920 and published in Zagreb in 1937. The author was captured in October 1914 and deported to Siberia, where he remained prisoner of war until 1920. Since there are few memoirs describing the life of Siberian prisoners during the First World War, this work is a precious testimony about the attitude towards the prisoners of war, human relations, and the survival of an AustroHungarian army officer. The book shows a striking lack of civilian or military hostility towards the prisoners and the respect of the Geneva Convention. Antun Vrgoč adopted the culture, customs and language of his formal enemies, took part in their civilian life, and taught at their university. His cathartic experience of survival includes a clear message about the absurdity of war.

[Study on processed senna found in health teas].

Takahashi, Mitsuko; Miyazawa, Maki; Sakurai, Katsumi; Watabe, Kenjiro; Kojima, Takashi

2009-12-01

Sennoside A and B were detected in 21 commercial health tea products surveyed in 2000-2007, but there were 8 products in which the leaves could not be identified as senna because the leaves had become discolored. The results of assay of sennoside levels and TLC chromatograms suggested that processed senna had been used in these products. Next, with reference to tea and health tea manufacturing methods, pharmaceutical senna was roasted or wet-processed experimentally. The results indicated that the discolored leaves contained in commercial health tea were most likely derived from senna leaves. Moreover, sennosides in medicinal doses were detected in some processed senna samples, and were determined to have a cathartic action in mice. Based on morphological confirmation and the results of component analysis, including sennoside, the discolored leaves found in commercial health teas were therefore determined to be senna leaves. There may be possible health risks, including diarrhea.

Nonverbal and verbal emotional expression and health.

Science.gov (United States)

Berry, D S; Pennebaker, J W

1993-01-01

The spontaneous nonverbal expression of emotion is related to immediate reductions in autonomic nervous system activity. Similar changes in specific autonomic channels occur when individuals are encouraged to verbally express their emotions. Indeed, these physiological changes are most likely to occur among individuals who are either verbally or nonverbally highly expressive. These data suggest that when individuals must actively inhibit emotional expression, they are at increased risk for a variety of health problems. Several experiments are summarized which indicate that verbally expressing traumatic experiences by writing or talking improves physical health, enhances immune function, and is associated with fewer medical visits. Although less research is available regarding nonverbal expression, it is also likely that the nonverbal expression of emotion bears some relation to health status. We propose that the effectiveness of many common expressive therapies (e.g., art, music, cathartic) would be enhanced if clients are encouraged to both express their feelings nonverbally and to put their experiences into words.

Vultures and others scavenger vertebrates associated with man-sized pig carcasses: a perspective in Forensic Taphonomy

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.

Pathologic bone tissues in a Turkey vulture and a nonavian dinosaur: implications for interpreting endosteal bone and radial fibrolamellar bone in fossil dinosaurs.

2009-09-01

We report on similar pathological bone microstructure in an extant turkey vulture (Cathartes aura) and a nonavian dinosaur from Transylvania. Both these individuals exhibit distinctive periosteal reactive bone deposition accompanied by endosteal bone deposits in the medullary cavity. Our findings have direct implications on the two novel bone tissues recently described among nonavian dinosaurs, radial fibrolamellar bone tissue and medullary bone tissue. On the basis of the observed morphology of the periosteal reactive bone in the turkey vulture and the Transylvanian dinosaur, we propose that the radial fibrolamellar bone tissues observed in mature dinosaurs may have had a pathological origin. Our analysis also shows that on the basis of origin, location, and morphology, pathologically derived endosteal bone tissue can be similar to medullary bone tissues described in nonavian dinosaurs. As such, we caution the interpretation of all endosteally derived bone tissue as homologous to avian medullary bone. (c) 2009 Wiley-Liss, Inc.

Vancomycin-resistant Enterococcus faecium bacteraemia as a complication of Kayexalate (sodium polystyrene sulfonate, SPS) in sorbitol-induced ischaemic colitis.

We present the case report of an 80-year-old woman with chronic kidney disease stage G5 admitted to the hospital with fluid overload and hyperkalaemia. Sodium polystyrene sulfonate (SPS, Kayexalate) in sorbitol suspension was given orally to treat her hyperkalaemia, which precipitated an episode of SPS in sorbitol-induced ischaemic colitis with the subsequent complication of vancomycin-resistant Enterococcus (VRE) bacteraemia. SPS (Kayexalate) in sorbitol suspension has been implicated in the development of intestinal necrosis. Sorbitol, which is added as a cathartic agent to decrease the chance of faecal impaction, may be primarily responsible through several proposed mechanisms. The gold standard of diagnosis is the presence of SPS crystals in the colon biopsy. On a MEDLINE search, no previous reports of a VRE bacteraemia as a complication of biopsy-confirmed SPS in sorbitol ischaemic colitis were found. To the best of our knowledge, ours would be the first such case ever reported. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

A retrospective study was conducted to identify the epidemiologic factors associated with gunshot injuries in raptors presented to the Wildlife Center of Virginia from 1993 to 2002. Of the 3,156 raptors admitted, 118 raptors (3.7%), representing 15 species, were admitted with gunshot trauma as the primary cause of morbidity and mortality. The majority of cases consisted of four species: red-tailed hawk (Buteo jamaicensis; 47%), red-shouldered hawk (Buteo lineatus; 14%), turkey vulture (Cathartes aura; 10%), and bald eagle (Haliaeetus leucocephalus; 8%). For species with greater than 40 admissions during the study period, the proportion of gunshot trauma of all causes of morbidity and mortality ranged from raptors with gunshot trauma were admitted during the fall and winter months (75%) compared with the spring and summer (25%). A significant decrease in the absolute number of gunshot cases per year was observed over the time period studied. The population-level effect of gunshot trauma is unknown for these species; however, it appears to be minor compared with other causes of morbidity and mortality.

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.

[The potential use of ayahuasca in psychiatry].

Science.gov (United States)

Frecska, Ede; Bokor, Petra; Andrassy, Gabor; Kovacs, Attila

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.

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 overall retinal topography, the total number of cells in the retinal ganglion cell layer, peak and average cell densities, cell soma area frequency distributions, and the theoretical peak anatomical spatial resolving power were the same in both species. This suggests that the visual systems of these two 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.

Kaschnitz, Enzensberger, and Sandig: The Ecopoetics of Water Pollution

Charlotte Melin

2016-01-01

Full Text Available This ecocritical reading of Marie Luise Kaschnitz’s poetic cycle “Rückkehr nach Frankfurt” ‘Return to Frankfurt’ (1945/46, Hans Magnus Enzensberger’s epic poem Der Untergang der Titanic ‘ The Sinking of the Titanic ’ (1978, and a 21^st-century poem by Ulrike Almut Sandig analyzes key shifts in poetic representations of water pollution. The essay explores underlying cultural and political attitudes about water that define literary depictions of its pollution. It argues that these texts register a conceptual turn away from aesthetic appreciation of water in terms of its culturally rich, purifying properties and toward scientific understanding that emphasizes the social and legal dimensions of water pollution. Ecocritical interpretation of such works, thus, enables deeper understanding of ongoing transformations in the lyric genre. The concluding interpretation of Sandig’s text points to the increasing presence of unnatural elements in representations of the environment as symptomatic of broader literary changes. It argues that developments in German nature poetry since 1945 have increasingly led poets to experiment with expressive possibilities for lyric poetry that foreground cathartic responses to human and environmental history.

An acid-pepsin digestion technique was used to examine portions of breast muscle and heart from raptors for encysted protozoans. Apicomplexan zoites were present in 52 (45.6%) of the 114 samples examined: 11 of 12 (91.7%) red-shouldered hawks (Buteo lineatus), 20 of 34 (58.8%) red-tailed hawks (Buteo jamaicensis), two of seven (28.6%) Cooper's hawks (Accipiter cooperi), three of four (75%) sharp-shinned hawks (Accipiter striatus), one (100%) Mississippi kites (Ictinia misisippiensis), one of two (50%) American kestrels (Falco sparverius), one bald eagle (Haliaeetus leucocephalus), one of two (50%) golden eagles (Aquila chrysaetos), one of three (33%) turkey vultures (Cathartes aura), two of three (66.7%) black vultures (Coragyps atratus), three of six (50%) great-horned owls (Bubo virginianus), five of 15 (33.3%) barred owls (Strix varia), and one of 12 (8.3%) screech owls (Asio otus). Encysted protozoans were not observed in digests of tissues from three broad-winged hawks (Buteo platypterus), four ospreys (Pandion haliaetus), and five barn owls (Tyto alba). Apicomplexan cysts resembling Sarcocystis species were observed in tissue sections of muscles from 28 (37.8%) of 74 raptors.

Full Text Available The state of Veracruz, Mexico has many water bodies which are used by both men and birds. This study surveyed the avifauna of the lagoons Maria Lizamba, la Piedra, and small sections of the rivers Camaron and Estanzuela in Tierra Blanca, Veracruz. During February 2010 visual surveys of these aquatic habitats were conducted by walking and motorboat, including vegetated areas and surrounding villages. Species were identified by comparing to field guides both visually using binoculars and identification of songs and calls. Forty nine species were documented and comprised 25 families. The most diverse families were the Ardeidae with 7 and Icteridae 6 species respectively. Sixteen families were represented by only a single species. We found 14 species of migratory birds and we found three species (Cathartes burrovianus, Psarocolius montezuma and Campylorhynchus rufinucha rufinucha considered to be at risk status according to the Mexican list of endangered and threatened species (NOM-059-SEMARNAT-2010. The avifauna was similar to that of the Alvarado Lagoon System, with between 17 % and 22 % of the species recently recorded there. The areas surrounding Maria Lizamba are used by numerous species of birds, however many species were aquatic and wintering migratory birds.

Naturally Occurring Anthraquinones: Chemistry and Therapeutic Potential in Autoimmune Diabetes

Directory of Open Access Journals (Sweden)

Shih-Chang Chien

2015-01-01

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.

Counselling against HIV in Africa: a genealogy of confessional technologies.

Science.gov (United States)

Nguyen, Vinh-Kim

2013-01-01

This paper contextualises counselling within a broader historical formation that links disclosure to healing and deploys confessional technologies to incite disclosure and awareness of the mysterious substance of the self. Foucault's argument that sexuality was the privileged arena for using confessional technologies to 'produce' the truth of the self is particularly relevant in light of the diffusion of counselling practices in Africa in the wake of the HIV epidemic, particularly with their emphasis on inciting appropriate sexual behaviour. Examination of the historical assemblage of counselling practices shows how they articulate what the self is, the nature of truth and a politics of language. This paper focuses on the genealogy of four key assumptions that express this confessional reason. These are that: (1) people can be 'empowered' to have control on their own lives by working on themselves, (2) secrets untold become pathogens, (3) the ability to heal requires that one first overcome personal illness, (4) the experience of sharing secrets is cathartic and healing. The genealogy intertwines four strands: that of the Unconscious as revealed by Freud and his followers, attempts to treat shell-shocked veterans of World War I, group psychotherapy and participatory research after World War II.

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.)

Recent self-harm and psychological measures in the emergency department

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.

Two types of peak emotional responses to music: The psychophysiology of chills and tears

Mori, Kazuma; Iwanaga, Makoto

2017-01-01

People sometimes experience a strong emotional response to artworks. Previous studies have demonstrated that the peak emotional experience of chills (goose bumps or shivers) when listening to music involves psychophysiological arousal and a rewarding effect. However, many aspects of peak emotion are still not understood. The current research takes a new perspective of peak emotional response of tears (weeping, lump in the throat). A psychophysiological experiment showed that self-reported chills increased electrodermal activity and subjective arousal whereas tears produced slow respiration during heartbeat acceleration, although both chills and tears induced pleasure and deep breathing. A song that induced chills was perceived as being both happy and sad whereas a song that induced tears was perceived as sad. A tear-eliciting song was perceived as calmer than a chill-eliciting song. These results show that tears involve pleasure from sadness and that they are psychophysiologically calming; thus, psychophysiological responses permit the distinction between chills and tears. Because tears may have a cathartic effect, the functional significance of chills and tears seems to be different. We believe that the distinction of two types of peak emotions is theoretically relevant and further study of tears would contribute to more understanding of human peak emotional response.

Scavenging plays an important role in shaping communities through inter- and intra-specific interactions. Although vertebrate scavenger efficiency and species composition is likely influenced by the spatial complexity of environments, heterogeneity in carrion distribution has largely been disregarded in scavenging studies. We tested this hypothesis by experimentally placing juvenile bird carcasses on the ground and in nests in trees to simulate scenarios of nestling bird carrion availability. We used cameras to record scavengers removing carcasses and elapsed time to removal. Carrion placed on the ground was scavenged by a greater diversity of vertebrates and at > 2 times the rate of arboreal carcasses, suggesting arboreal carrion may represent an important resource to invertebrate scavengers, particularly in landscapes with efficient vertebrate scavenging communities. Nonetheless, six vertebrate species scavenged arboreal carcasses. Rat snakes (Elaphe obsolete), which exclusively scavenged from trees, and turkey vultures (Cathartes aura) were the primary scavengers of arboreal carrion, suggesting such resources are potentially an important pathway of nutrient acquisition for some volant and scansorial vertebrates. Our results highlight the intricacy of carrion-derived food web linkages, and how consideration of spatial complexity in carcass distribution (i.e., arboreal) may reveal important pathways of nutrient acquisition by invertebrate and vertebrate scavenging guilds.

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

Lane, Robert C

2002-02-01

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.

Popular theatre and nonformal education in the Third World: Five strands of experience

Science.gov (United States)

Kidd, Ross

1985-09-01

Popular theatre is gaining increasing attention in the Third World as a tool for popular education and community organizing. It finds expression in a number of forms including drama, music dance, puppetry and poetry and is performed for — and often by — ordinary peasants and workers. Popular theatre is used as a means of bringing people together, building confidence and solidarity, stimulating discussion, exploring alternative options for action, and building a collective commitment to change: starting with people's urgent concerns and issues, it encourages reflection on these issues and possible strategies for change. Popular theatre, however, is not a unified discipline. It is used by different groups for different interests, ranging from a technocratic, message-oriented `domestication theatre' at one end of the spectrum to a process of consciousness-raising, organization-building and struggle at the other end. Five main strands of popular theatre can be distinguished: (a) the struggle for national liberation; (b) mass education and rural extension; (c) community or participatory development; (d) `conscientization' or popular education; and (e) popular education and organizing. At its best, popular theatre is not an isolated performance or a cathartic experience, but part of an ongoing process of education and organizing, aimed at overcoming oppression and dependence, and at securing basic rights.

Activation analyses of authenticated hairs of Napoleon Bonaparte confirm arsenic poisoning.

In 1960, activation analyses at the Harwell Nuclear Research Laboratory of the University of Glascow, London of authenticated hairs of Napoleon Bonaparte taken immediately after his death confirmed Napoleon's chronic arsenic poisoning on the island of St. Helena. Timeline correlation of his clinical symptomatology of the preceding 4 months, as reported in the written diaries of his exiled companions, further supports the effect of fluctuating, elevated toxic levels of arsenic on his health. Independent analyses of authenticated hairs of Napoleon by the Toxicology Crime Laboratory of the United States Federal Bureau of Investigation in 1995 reveals toxic levels of arsenic. The successful assassination of Napoleon included both a cosmetic and lethal phase. The cosmetic phase consisted of arsenic poisoning over time to weaken Napoleon, making the associated debility appear to be a natural illness and thus allay any suspicions prior to instituting the lethal phase. On May 3, 1821, at 5:30 P.M., the lethal phase was carried out. Napoleon was given Calomel (HgCl), a cathartic, and a popular orange-flavored drink called orgeat, which was flavored with the oil of bitter almonds. Together they formed mercury cyanide, which is lethal. Napoleon lost consciousness and died two days later.

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.)

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.

Deleterious effects of magnesium intoxication upon the domestic broiler chick

Lee, S.R.

Dietary levels of 0.6 to 0.8% magnesium in a corn-soy basal were rachitogenic. These rickets appeared most like phosphorus deficiency. Bone Ca/P ratios were numerically quite low implying a lack of transformation from amorphous calcium phosphate to hydroxyapatite. Bone alkaline phosphatase activity was elevated. Additional dietary phosphorus ameliorated, but could not overcome the rachitogenic effects of magnesium. Tibial dyschondroplasia (TD), induced by elevated dietary P, was decreased by high levels of dietary Mg, but with no decrease in plasma phosphorus. Anticoccidial ionophores fed in conjunction with a moderate dietary challenge of Mg (0.48%) produced no clear changes in plasma calcium or Mg, but did interact to reduce body weight. The diarrhea caused by magnesium intoxication is not due to hyperosmotic loads of Mg per se. Rather, Cl was observed to be the major ionic constituent of the gut osmotic load implying different gut ionic fluxes in control versus magnesium intoxicated chicks. These data imply that the cathartic action of Mg is due to hypersecretion of the gut. Effects mediated or modified by the CNS changed in magnesium intoxicated chicks. Such chicks appeared cold and stayed near the heat. When startled, they exhibited extreme avoidance behavior and seizures similar to epilepsy and/or Cl deficiency. Brain tissue Mg content did not concomitantly increase. Whether these effects are due to central signals is unclear.

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.

A Review of Training Methods and Instructional Techniques: Implications for Behavioral Skills Training in U.S. Astronauts (DRAFT)

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 Constipation is one of themost common chronic gastrointestinal problems. The estimated incidence of constipation in the United States is3% to 19% in general population.1,2 Patientswith head injuries, spinal cord injuries, pelvic fractures, lower extremity fractures ormultiple traumas require a long-term bed rest, during which the incidence of constipation reached as high as 50%.3,4 Constipation always brings inconvenience and tremendous suffering to patientsand strongly influences the recovery from primary disease. Irritants or lubricants can relieve the symptoms, but long-term application of them may lead to side effects like melanosis coli5 and cathartic colon6. The absorption of fat soluble vitamins is also affected.7 Polyethylene glycol 4000 (trade name: Forlax®, a long chain polymer with a high molecular weight, can conjugate withwater molecule through hydrogen bond to increase the water content and volume of stools, thereby, facilitate bowelmovement and defecation.8,9 It is neither absorbed nor metabolized in the digestive tract, hence it is highly safe and well tolerable. Thus, long-term medication of polyethylene glycol 4000 is conducive to the reconstruction of normal defecation pattern. Therefore, polyethylene glycol 4000 is now being widely used as the mainstay adult chronic functional constipation management.10,11 The aim of this study was to verify the efficacy and safety of polyethylene glycol 4000 on adult functional constipation of posttraumatic bedridden patients.

Acetylcholinesterase inhibition by organophosphorus pesticides or organophosphate nerve agents can cause acute parasympathetic system dysfunction, muscle weakness, seizures, coma, and respiratory failure. Prognosis depends on the dose and relative toxicity of the specific compound, as well as pharmacokinetic factors. We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for acute organophosphorus poisoning? We searched: Medline, Embase, The Cochrane Library, and other important databases up to April 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 62 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: activated charcoal (single or multiple doses), alpha(2) adrenergic receptor agonists, atropine, benzodiazepines, butyrylcholinesterase replacement therapy, cathartics, extracorporeal clearance, gastric lavage, glycopyrronium bromide (glycopyrrolate), ipecacuanha (ipecac), magnesium sulphate, milk or other home remedy immediately after ingestion, N-methyl-D-aspartate receptor antagonists, organophosphorus hydrolases, oximes, removing contaminated clothes and washing the poisoned person, and sodium bicarbonate.

Recording the Personal: The Benefits in Maintaining Research Diaries for Documenting the Emotional and Practical Challenges of Fieldwork in Unfamiliar Settings

Full Text Available Through an analysis of personal research diaries maintained during a prolonged period spent working in Palestine, this article analyses the importance of maintaining research diaries when on fieldwork. The evidence produced stems from a content analysis of fieldwork diaries kept while researching commemorative events in the West Bank, Palestine, during a period of global uncertainty and at a time of much change in the region. In espousing the benefits of the fieldwork diary it is shown that diaries assume a more important role than acting as a mere logging device; they have the capacity to allow for personal reflection and to help with the development of strategic responses to the inevitable challenges one would expect to face when working far from the relative comfort of home. The research diary as a cathartic tool for researchers to record fears and shortcomings in their work is discussed and personal insights into some of the challenges this researcher faced when engaged in ethnographic work in Ramallah, Palestine are provided. In summarising the benefits of maintaining research diaries, the author, lamenting the lack of transparency in the literature to date on the practicalities of fieldwork, calls for more open and honest reflection on the challenges associated with conducting fieldwork, particularly that which takes place in volatile or unstable regions.

[Fire worship on Soratte: form prehistory to present days].

Falchetti, Mario; Ottini, Laura

2013-01-01

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.

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.

HR Khorshidi

2006-10-01

Introduction & Objective: Non-traumatic colon perforations are usually caused by malignancy, diverticulum and colitis. Stercoraceous perforation of the colon has rarely been reported in the literature. This lesion is assumed to be produced by the pressure from a hard scybalum resulting in a perforated ulcer with necrotic edges. We report a case of stercoraceous perforation of the cecum due to scybalum. Case: We report a 50-year-old man who had a severe abdominal pain from 3 days ago and had peritonitis in physical exam. He was admitted in Mars, 2005 at Mobasher Kashani Hospital in Hamadan and he was parapelegic from 8 months ago due to trauma in his medical history and then he had severe and chronic constipation that necessitated the use of cathartic drugs. We operated him with diagnosis of peritonitis, and perforation of cecum due to scybalum was seen and right hemicolectomy and colostomy and ileostomy was done. Conclusion: The most common site of colon perforation due to scybalum is rectosigmoid area and cecal perforation is a rare area in the literature. It is presented with peritonitis in old patients that have chronic constipation. It is difficult to diagnose this lesion preoperatively. This lesion was only 11% correctly diagnosed before operation and should be always suspected when a patient with chronic constipation suffers from sudden abdominal pain. Resection and colostomy is the treatment of choice in most situations.

Lignans and flavonols are the primary constituents of Sinopodophyllum emodi and have been used as cathartic, anthelmintic, chemotherapeutic and anti-hypertensive compounds. Although these compounds have been isolated, there have been no reports on the separation of 4'-demethyl podophyllotoxin, podophyllotoxin, deoxypodophyllotoxin and kaempferol in one step by medium-pressure liquid chromatography (MPLC) and high-speed counter-current chromatography (HSCCC). Development of an efficient method for the preparative separation and purification of three lignans and one flavonol from S. emodi. The precipitate of crude extracts was first separated by MPLC into four parts, numbered GJ-1, GJ-2, GJ-3 and GJ-4. GJ-1 was separated and purified by HSCCC using a solvent system composed of n-hexane:ethyl acetate:methanol:water (1.75:1.5:1:0.75, v/v/v/v). The purities of the target compounds were assessed using high-performance liquid chromatography (HPLC) and chemical structures were identified by (1) H-NMR and (13) C-NMR. The HSCCC and MPLC methods were successfully used for the preparative separation and purification of 4'-demethyl podophyllotoxin (8.5 mg, 92.4%), podophyllotoxin (40.1 mg, 92.1%), deoxypodophyllotoxin (4.6 mg, 98.1%), and kaempferol (1.6 mg, 96.7%) from a 100 mg sample. Three lignans (4'-demethyl podophyllotoxin, podophyllotoxin, deoxypodophyllotoxin) and one flavonol (kaempferol) were successfully isolated by HSCCC and MPLC in one step.

Literature and disability: the medical interface in Borges and Beckett.

Novillo-Corvalán, Patricia

2011-06-01

Samuel Beckett and Jorge Luis Borges have presented 20th century literature with a distinctive gallery of solitary figures who suffer from a series of physiological ailments: invalidism, decrepitude, infirmity and blindness, as well as neurological conditions such as amnesia and autism spectrum disorders. Beckett and Borges were concerned with the dynamics between illness and creativity, the literary representation of physical and mental disabilities, the processes of remembering and forgetting, and the inevitability of death. This article explores the depiction of physically and mentally disabled characters in Borges' Funes the Memorious (1942)--a story about an Uruguayan gaucho who has been left paralysed after a fall from a horse which simultaneously endowed him with an infallible memory and perception--and Beckett's Trilogy: Molloy (1951), Malone Dies (1951) and The Unnamable (1953). It examines the prodigious memory of Funes and the forgetful minds of Molloy and Malone with reference to influential neuropsychological studies such as Alexander Luria's twofold exploration of memory and forgetfulness in The Mind of a Mnemonist (1968) and The Man with a Shattered World (1972). The article demonstrates that in contrast to Beckett's amnesiacs and Luria's brain-damaged patient, who are able to transcend their circumstances through cathartic writing, Borges' and Luria's mnemonic prodigies fail to achieve anything significant with their unlimited memories and remain imprisoned within their cognitive disabilities. It reveals that medical discourses can provide invaluable insights and lead to a deeper understanding of the minds and bodily afflictions of literary characters.

Movement ecology of migration in turkey vultures.

We develop individual-based movement ecology models (MEM) to explore turkey vulture (Cathartes aura) migration decisions at both hourly and daily scales. Vulture movements in 10 migration events were recorded with satellite-reporting GPS sensors, and flight behavior was observed visually, aided by on-the-ground VHF radio-tracking. We used the North American Regional Reanalysis dataset to obtain values for wind speed, turbulent kinetic energy (TKE), and cloud height and used a digital elevation model for a measure of terrain ruggedness. A turkey vulture fitted with a heart-rate logger during 124 h of flight during 38 contiguous days showed only a small increase in mean heart rate as distance traveled per day increased, which suggests that, unlike flapping, soaring flight does not lead to greatly increased metabolic costs. Data from 10 migrations for 724 hourly segments and 152 daily segments showed that vultures depended heavily upon high levels of TKE in the atmospheric boundary layer to increase flight distances and maintain preferred bearings at both hourly and daily scales. We suggest how the MEM can be extended to other spatial and temporal scales of avian migration. Our success in relating model-derived atmospheric variables to migration indicates the potential of using regional reanalysis data, as here, and potentially other regional, higher-resolution, atmospheric models in predicting changing movement patterns of soaring birds under various scenarios of climate and land use change.

Full Text Available BACKGROUND: Stool examination by counting eggs per gram of feces (EPGs is the best method to estimate worm burden of Clonorchis sinensis in infected humans. The present study investigated a correlation between EPGs and worm burden in human clonorchiasis. METHODS AND FINDINGS: A total of 60 residents, 50 egg-positive and 10 egg-negative, in Sancheong-gun, Korea, participated in this worm collection trial in 2006-2009. They were diagnosed by egg positivity in feces using the Kato-Katz method. After administration of praziquantel, they were purged with cathartics on the next day, and then discharged adult worms were collected from their feces. Their EPGs ranged from 0 to 65,544. Adult worms of C. sinensis were collected from 17 egg-positive cases, and the number of worms ranged from 1 to 114 in each individual. A positive correlation between EPGs and numbers of worms was demonstrated (r = 0.681, P<0.001. Worm recovery rates were 9.7% in cases of EPGs 1-1,000 and 73.7% in those of EPGs over 1,000. No worms were detected from egg-negative subjects. Maximum egg count per worm per day was roughly estimated 3,770 in a subject with EPGs 2,664 and 106 collected worms. CONCLUSIONS: The numbers of the worms are significantly correlated with the egg counts in human clonorchiasis. It is estimated that at least 110 worms are infected in a human body with EPGs around 3,000, and egg productivity of a worm per day is around 4,000.

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 Background: The role of surgery in treating children with functional constipation (FC is controversial, because of the efficacy of bowel management programs. This case series is comprised of failures: 43 children, spanning 25 years' practice, who had megarectosigmoid (MRS and unremitting constipation. Purpose: To determine whether these children were helped by surgery, and to contribute to formulating a standard of care for children with megarectum (MR and/or redundancy of the sigmoid colon (MS who fail medical management. Method: We describe our selection criteria and the procedures we utilized – mucosal proctectomy and endorectal pull-through (MP or sigmoidectomy (SE with colorectal anastomosis at the peritoneal reflection. The internet (social media allowed us to contact most of these patients and obtain extremely long follow-up data. Results: 30/43 patients had MP and 13/43 had SE. Follow-up was obtained in 83% MP and 70% SE patients. 60% of MP and 78% of SE patients reported regular evacuations and no soiling. 20% MP patients had occasional urgency or soiling or episodic constipation. 12% MP and 22% SE patients required antegrade continence enemas (ACE or scheduled cathartics and/or stool softeners. 4% MP had no appreciable benefit, frequent loose stools and soiling, presumably from encopresis. Conclusion: MR is characterized by diminished sensation, poor compliance and defective contractility. Patients with MR do better with MP, which effectively removes the entire rectum versus SE, where normal caliber colon is anastomosed to MR at the peritoneal reflection; furthermore, MP reliably preserves continence; whereas total proctectomy (trans-anal or trans-abdominal may cause incontinence.

Ecballium Elaterium Poisoning in Pediatric Emergency Service: A Case Report

Directory of Open Access Journals (Sweden)

Sinem Sarı Gökay

2018-01-01

Full Text Available Background Ecballium elaterium is the only species belonging to the genus Ecballium of Cucurbitaceae family. It is native to the Mediterranean region. Despite its side effects, E. elaterium has still been being used as an alternative treatment agent for sinusitis, cirrhosis, rheumatic diseases and hemorrhoids for its anti-inflammatory and cathartic actions. Herein we discuss a pediatric case showing gastrointestinal side effects after ingesting E. elaterium. Case Report: A six-year-old boy admitted to Çukurova University Medical Faculty Pediatric Emergency Department, Turkey, for vomiting one hour after ingesting a green plant which he had tasted to satisfy his curiosity. Physical examination, vital signs and laboratory tests revealed normal. The ingested plant was defined to be E. elaterium. Maintenance fluid infusion, 1 mg/kg ranitidine and sucralfate medications were commenced. During the follow-up, the patient developed numbness of the tongue and hyper-salivation, without any signs of uvular edema or other system findings. Further follow-up showed stable vital signs within the normal range with no additional complications. The patient was sent home with the cure and recommendations. Discussion: The plants and herbs that are used as agents of alternative or complementary medicine may as well be accidentally or curiously taken by children leading to unwanted intoxication cases. Pre-encounter actions to prevent such cases are as important as any post-exposure clinical interventions to impede the unwanted consequences. One such measure might be a more intensive public information policy underscoring the fact that plants have the potential to be noxious and may cause serious side effects and even death.

Soaring migratory birds avoid wind farm in the Isthmus of Tehuantepec, southern Mexico.

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.

A pilot golden eagle population study in the Altamont Pass Wind Resource Area, California

Orloff and Flannery (1992) estimated that several hundred reports are annually killed by turbine collisions, wire strikes, and electrocutions at the Altamont Pass Wind Resource Area (WRA). The most common fatalities were those of red-tailed hawks (Buteo jamaicensis), American kestrels (Falco sparvatius), and golden eagles (Aquila chrysaetos), with lesser numbers of turkey vultures (Cathartes aura), common ravens (Corvus corax), bam owls (Tyto alba), and others. Among the species of raptors killed at Altamont Pass, the one whose local population is most likely to be impacted is the golden eagle. Besides its being less abundant than the others, the breeding and recruitment rates of golden eagles are naturally slow, increasing their susceptibility to decline as a result of mortality influences. The golden eagle is a species afforded special federal protection because of its inclusion within the Bald Eagle Protection Act as amended in 1963. There are no provisions within the Act which would allow the killing ``taking`` of golden eagles by WRA structures. This report details the results of field studies conducted during 19941. The primary purpose of the investigation is to lay the groundwork for determining whether or not turbine strikes and other hazards related to energy at Altamont Pass may be expected to affect golden eagles on a population basis. We also seek an understanding of the physical and biotic circumstances which attract golden eagles to the WRA within the context of the surrounding landscape and the conditions under which they are killed by wind turbines. Such knowledge may suggest turbine-related or habitat modifications that would result in a lower incidence of eagle mortality.

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.

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.

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.

The effects of activated charcoal (AC) mixed with cathartics for gastric decontamination in the management of organophosphate (OP) poisoning remain unknown due to limited clinical evidence. This exploratory study assessed the effectiveness of premixed AC-sorbitol as a treatment for OP poisoning. This retrospective observational case study included patients who either did not receive AC-sorbitol or received a single dose of AC-sorbitol within 24 h after OP ingestion. The patients were divided into three groups: no AC-sorbitol treatment, patients who received AC-sorbitol within 1 h of OP ingestion, and patients who received AC-sorbitol more than 1 h after OP ingestion. Mortality, the development of respiratory failure, and the duration of mechanical ventilation were used as outcome measurements for effectiveness, whereas aspiration pneumonia and electrolyte imbalance were employed as safety measurements. Among 262 patients with OP poisoning, 198 were included. Of these, 133 patients did not receive AC-sorbitol, whereas 14 and 51 patients received AC-sorbitol within 1 h or more than 1 h after ingestion, respectively. The time from ingestion to hospital arrival and time from ingestion to administration of atropine and pralidoxime differed among the groups, whereas other characteristics, including age, amount ingested, and type of ingested OP, were similar among the groups. Univariate and multivariate analysis demonstrated that the administration of AC-sorbitol was not associated with outcome measures for effectiveness and did not significantly increase either aspiration pneumonia or electrolyte imbalances during hospitalization. The administration of AC-sorbitol exerted neither beneficial nor harmful effects on the outcomes of OP-poisoned patients regardless of the time from OP ingestion to administration, compared with those of patients who did not receive AC-sorbitol. However, this study enrolled a small number of patients who received AC-sorbitol; further qualified

Stop and Smell the Pollen: The Role of Olfaction and Vision of the Oriental Honey Buzzard in Identifying Food.

Full Text Available 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.

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.

The avoidance of motorized vehicles is a common challenge for birds in the modern world. Birds appear to rely on antipredator behaviors to avoid vehicles, but modern vehicles (automobiles and aircraft) are faster than natural predators. Thus, birds may be relatively ill-equipped, in terms of sensory capabilities and behaviors, to avoid vehicles. We examined the idea that birds may be unable to accurately assess particularly high speeds of approaching vehicles, which could contribute to miscalculations in avoidance behaviors and ultimately cause collisions. We baited turkey vultures (Cathartes aura) to roads with animal carcasses and measured flight initiation distance and effective time-to-collision in response to a truck driving directly towards vultures from a starting distance of 1.13 km and at one of three speeds: 30, 60, or 90 kph (no vultures were struck). Flight initiation distance of vultures increased by a factor of 1.85 as speed increased from 30 to 90 kph. However, for 90-kph approaches there was no clear trend in flight initiation distance across replicates: birds appeared equally likely to initiate escape behavior at 40 m as at 220 m. Time-to-collision decreased by a factor of 0.62 with approach speeds from 30 to 90 kph. Also, at 90 kph, four vehicle approaches (17%) resulted in near collisions with vultures (time-to-collision ≤1.7 s), compared to none during 60 kph approaches and one during 30 kph approaches (4%). Our findings suggest that antipredator behaviors in turkey vultures, particularly stimulus processing and response, might not be well tuned to vehicles approaching at speeds ≥90 kph. The possible inability of turkey vultures to react appropriately to high-speed vehicles could be common among birds, and might represent an important determinant of bird-vehicle collisions.

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.

Rice syrup solids, rice protein, and casein hydrolysate were added to experimental oral rehydration solutions in various combinations and tested in a rat intestinal perfusion system. Chronic osmotic diarrhea was induced in juvenile rats by supplying the cathartic agents, magnesium citrate and phenolphthalein, in their drinking water for 1 week. The experimental oral rehydration solutions were compared with standard oral rehydration solutions containing 20 gm/L or 30 gm/L of glucose and with each other to determine if there were significant differences in net water, sodium, or potassium absorption. An oral rehydration solution containing 30 gm/L of rice syrup solids had a net water absorption rate significantly higher than that of the standard 20 gm/L glucose-based oral rehydration solution (2.1 +/- 0.62 versus 1.5 +/- 0.48 microliters/[min x cm], p less than 0.05). Casein hydrolysate did not significantly affect net water absorption. However, combinations of 30 gm/L rice syrup solids and 5 gm/L casein hydrolysate significantly increased (p less than 0.05) net sodium and potassium absorption compared with the 20 gm/L glucose-based oral rehydration solution but not versus rice syrup solids alone. Oral rehydration solutions containing 30 gm/L rice syrup solids plus 5 gm/L rice protein, and 30 gm/L rice syrup solids plus 5 gm/L casein hydrolysate, had net water absorption rates significantly higher than the rate of a 30 gm/L glucose-based oral rehydration solution (2.5 +/- 0.36 and 2.4 +/- 0.38, respectively, versus 0.87 +/- 0.40 microliters/[min x cm], p less than 0.05). Rice protein and casein hydrolysate, however, did not significantly affect net water, sodium, or potassium absorption when added to rice protein glucose-based oral rehydration solutions. An inverse correlation between osmolality and net water absorption was observed (r = -0.653, p less than 0.02). The data suggest that substitution of rice syrup solids for glucose in oral rehydration solutions will

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

aimed at preventing aspiration pneumonia and the animal's absorption of highly volatile components. Activated charcoal slurries and, in some instances, vegetable oil may be used to absorb the ingested petroleum or alter its viscosity to minimize absorption and aspiration. These procedures should be followed by the administration of rumenatories or saline cathartics to hasten the evacuation of the gastrointestinal tract. Chronic poor performance animals with anorexia and rumen dysfunction may respond to fresh rumen inoculant, intravenous glucose, and B-complex vitamins. Prognosis primarily hinges on whether or not aspiration pneumonia has occurred. Treatment of aspiration pneumonia rarely is effe

The inconstant "principle of constancy".

Kanzer, M

1983-01-01

A review of the principle of constancy, as it appeared in Freud's writings, shows that it was inspired by his clinical observations, first with Breuer in the field of cathartic therapy and then through experiences in the early usage of psychoanalysis. The recognition that memories repressed in the unconscious created increasing tension, and that this was relieved with dischargelike phenomena when the unconscious was made conscious, was the basis for his claim to originality in this area. The two principles of "neuronic inertia" Freud expounded in the Project (1895), are found to offer the key to the ambiguous definition of the principle of constancy he was to offer in later years. The "original" principle, which sought the complete discharge of energy (or elimination of stimuli), became the forerunner of the death drive; the "extended" principle achieved balances that were relatively constant, but succumbed in the end to complete discharge. This was the predecessor of the life drives. The relation between the constancy and pleasure-unpleasure principles was maintained for twenty-five years largely on an empirical basis which invoked the concept of psychophysical parallelism between "quantity" and "quality." As the links between the two principles were weakened by clinical experiences attendant upon the growth of ego psychology, a revision of the principle of constancy was suggested, and it was renamed the Nirvana principle. Actually it was shifted from alignment with the "extended" principle of inertia to the original, so that "constancy" was incongruously identified with self-extinction. The former basis for the constancy principle, the extended principle of inertia, became identified with Eros. Only a few commentators seem aware of this radical transformation, which has been overlooked in the Standard Edition of Freud's writings. Physiological biases in the history and conception of the principle of constancy are noted in the Standard Edition. The historical

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

Castor oil, a potent cathartic, is derived from the bean of the castor plant. Anecdotal reports, which date back to ancient Egypt have suggested the use of castor oil to stimulate labour. Castor oil has been widely used as a traditional method of initiating labour in midwifery practice. Its role in the initiation of labour is poorly understood and data examining its efficacy within a clinical trial are limited. This is one of a series of reviews of methods of cervical ripening and labour induction using standardised methodology. To determine the effects of castor oil or enemas for third trimester cervical ripening or induction of labour in comparison with other methods of cervical ripening or induction of labour. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 April 2013) and bibliographies of relevant papers. Clinical trials comparing castor oil, bath or enemas used for third trimester cervical ripening or labour induction with placebo/no treatment or other methods listed above it on a predefined list of labour induction methods. A strategy was developed to deal with the large volume and complexity of trial data relating to labour induction. This involved a two-stage method of data extraction. Three trials, involving 233 women, are included. There was no evidence of differences in caesarean section rates between the two interventions in the two trials reporting this outcome (risk ratio (RR) 2.04, 95% confidence interval (CI) 0.92 to 4.55). There were no data presented on neonatal or maternal mortality or morbidity.There was no evidence of a difference between castor oil and placebo/no treatment for the rate of instrumental delivery, meconium-stained liquor, or Apgar score less than seven at five minutes. The number of participants was too small to detect all but large differences in outcome. All women who ingested castor oil felt nauseous (RR 59.92, 95% CI 8.46 to 424.52). The three trials included in the review contain small numbers

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.

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

The mechanisms that enable meadow mice to utilize Salicornia are not clearly understood.Measurements of harvest mouse evaporative water loss are among the highest reported for small mammals (1.35 mg H 2 O/cc O 2 consumed). On the basis of these data and other information in the literature, a water budget was constructed. The results suggest that harvest mice may enter daily torpor in response to osmotic stress or water deprivation.The role of dew and fog precipitation in the ecology of small rodents inhabiting coastal marshes is discussed. Apparently a sufficient amount of free water is available to meet the requirements of the salt marsh populations, although the quality of the available water may be influenced by salt-excretion activity of certain halophytes. Less halophytic succulents are available in the coastal marshes; these species may be more readily utilized than Salicornia by small vertebrates.

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.

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

Plant materials derived from the Aloe plant are used as cosmetic ingredients, including Aloe Andongensis Extract, Aloe Andongensis Leaf Juice, Aloe Arborescens Leaf Extract, Aloe Arborescens Leaf Juice, Aloe Arborescens Leaf Protoplasts, Aloe Barbadensis Flower Extract, Aloe Barbadensis Leaf, Aloe Barbadensis Leaf Extract, Aloe Barbadensis Leaf Juice, Aloe Barbadensis Leaf Polysaccharides, Aloe Barbadensis Leaf Water, Aloe Ferox Leaf Extract, Aloe Ferox Leaf Juice, and Aloe Ferox Leaf Juice Extract. These ingredients function primarily as skin-conditioning agents and are included in cosmetics only at low concentrations. The Aloe leaf consists of the pericyclic cells, found just below the plant's skin, and the inner central area of the leaf, i.e., the gel, which is used for cosmetic products. The pericyclic cells produce a bitter, yellow latex containing a number of anthraquinones, phototoxic compounds that are also gastrointestinal irritants responsible for cathartic effects. The gel contains polysaccharides, which can be acetylated, partially acetylated, or not acetylated. An industry established limit for anthraquinones in aloe-derived material for nonmedicinal use is 50 ppm or lower. Aloe-derived ingredients are used in a wide variety of cosmetic product types at concentrations of raw material that are 0.1% or less, although can be as high as 20%. The concentration of Aloe in the raw material also may vary from 100% to a low of 0.0005%. Oral administration of various anthraquinone components results in a rise in their blood concentrations, wide systemic distribution, accumulation in the liver and kidneys, and excretion in urine and feces; polysaccharide components are distributed systemically and metabolized into smaller molecules. aloe-derived material has fungicidal, antimicrobial, and antiviral activities, and has been effective in wound healing and infection treatment in animals. Aloe barbadensis (also known as Aloe vera)-derived ingredients were not toxic
