After Satan : Essays in Honour of Neil Forsyth

This volume is the result of a collective desire to pay homage to Neil Forsyth, whose work has significantly contributed to scholarship on Satan. This volume is "after" Satan in more ways than one, tracing the afterlife of both the satanic figure in literature and of Neil Forsyth's contribution to the field, particularly in his major books The Old Enemy: Satan and the Combat Myth (Princeton University Press, 1987, revised 1990) and The Satanic Epic (Princeton University Press, 2003). The essays in this volume draw on Forsyth's work as a focus for their analyses of literary encounters with evil or with the Devil himself, reflecting the richness and variety of contemporary approaches to the age-old question of how to represent evil. All the contributors acknowledge Neil Forsyth's influence in the study of both the Satan-figure and Milton's Paradise Lost. But beyond simply paying homage to Neil Forsyth, the articles collected here trace the lineage of the Satan figure through literary history, showing how evil can function as a necessary other against which a community may define itself. They chart the demonised other through biblical history and medieval chronicle, Shakespeare and Milton, to nineteenth-century fiction and the contemporary novel. Many of the contributors find that literary evil is mediated through the lens of the Satan of Paradise Lost, and their articles address the notion, raised by Neil Forsyth in The Satanic Epic, that the literary Devil-figures under consideration are particularly interested in linguistic ambivalence and the twisted texture of literary works themselves. The multiple responses to evil and the continuous reinvention of the devil figure through the centuries all reaffirm the textual presence of the Devil, his changing forms necessarily inscribed in the shifting history of western literary culture. These essays are a tribute to the work of Neil Forsyth, whose scholarship has illuminated and guided the study of the Devil in English and other literatures.

Documenting a time-bound, circular view of hierarchies: a microanalysis of parent-infant dyadic interaction.

This article presents a new theory that separates the levels of communication and relates them circularly, namely, by separating time from space/meaning variables. Documenting this proposition requires sequential microdescriptions--a far-out project in the field of family therapy. In an extensive study of clinical and nonclinical families, starting with available microanalytic data on nonverbal parent-infant dialogue, distinct time organizations have been found to modify the degree of circularity between the levels of interaction according to the observed types of engagement, that is, consensual, conflictual, and paradoxical. The double description of the dyad as a totality versus the dyad as a framing/developing organization imparts crucial information on how development proceeds in dyadic, co-evolutive systems, and presumably in larger ones too. In this perspective, a model is elaborated and then applied to a case description in our therapeutic consultation.

Reliability and validity of physiological data obtained within a cycle-run transition test in age-group triathletes.

This study examined the validity and reliability of a sequential "Run-Bike-Run" test (RBR) in age-group triathletes. Eight Olympic distance (OD) specialists (age 30.0 ± 2.0 years, mass 75.6 ± 1.6 kg, run VO2max 63.8 ± 1.9 ml· kg(-1)· min(-1), cycle VO2peak 56.7 ± 5.1 ml· kg(-1)· min(-1)) performed four trials over 10 days. Trial 1 (TRVO2max) was an incremental treadmill running test. Trials 2 and 3 (RBR1 and RBR2) involved: 1) a 7-min run at 15 km· h(-1) (R1) plus a 1-min transition to 2) cycling to fatigue (2 W· kg(-1) body mass then 30 W each 3 min); 3) 10-min cycling at 3 W· kg(-1) (Bsubmax); another 1-min transition and 4) a second 7-min run at 15 km· h(-1) (R2). Trial 4 (TT) was a 30-min cycle - 20-min run time trial. No significant differences in absolute oxygen uptake (VO2), heart rate (HR), or blood lactate concentration ([BLA]) were evidenced between RBR1 and RBR2. For all measured physiological variables, the limits of agreement were similar, and the mean differences were physiologically unimportant, between trials. Low levels of test-retest error (i.e. ICC <0.8, CV<10%) were observed for most (logged) measurements. However [BLA] post R1 (ICC 0.87, CV 25.1%), [BLA] post Bsubmax (ICC 0.99, CV 16.31) and [BLA] post R2 (ICC 0.51, CV 22.9%) were least reliable. These error ranges may help coaches detect real changes in training status over time. Moreover, RBR test variables can be used to predict discipline specific and overall TT performance. Cycle VO2peak, cycle peak power output, and the change between R1 and R2 (deltaR1R2) in [BLA] were most highly related to overall TT distance (r = 0.89, p < 0. 01; r = 0.94, p < 0.02; r = 0.86, p < 0.05, respectively). The percentage of TR VO2max at 15 km· h(-1), and deltaR1R2 HR, were also related to run TT distance (r = -0.83 and 0.86, both p < 0.05).

Properties of ideal composite knots.

The shortest tube of constant diameter that can form a given knot represents the 'ideal' form of the knot. Ideal knots provide an irreducible representation of the knot, and they have some intriguing mathematical and physical features, including a direct correspondence with the time-averaged shapes of knotted DNA molecules in solution. Here we describe the properties of ideal forms of composite knots-knots obtained by the sequential tying of two or more independent knots (called factor knots) on the same string. We find that the writhe (related to the handedness of crossing points) of composite knots is the sum of that of the ideal forms of the factor knots. By comparing ideal composite knots with simulated configurations of knotted, thermally fluctuating DNA, we conclude that the additivity of writhe applies also to randomly distorted configurations of composite knots and their corresponding factor knots. We show that composite knots with several factor knots may possess distinct structural isomers that can be interconverted only by loosening the knot.

Aider les étudiants en médecine à approcher la mort [Helping medical students to approach death].

A project recently launched by the Faculty of biology and medicine of Lausanne introduces the approach of facing death during both the dissection and the course of clinical activities. Existential questions relating to mortality are bound to arise sooner or later during the course of the study. For the sake of humanized clinical practice, these questions must be confronted. In response to a request by a student association, an accompanying curriculum with active student's contribution through encounters with death in anatomy and clinical situations was created in Lausanne. Students will benefit from this new program throughout their curriculum. This program is the first of its kind in Switzerland.

Letrozole therapy alone or in sequence with tamoxifen in women with breast cancer.

BACKGROUND: The aromatase inhibitor letrozole, as compared with tamoxifen, improves disease-free survival among postmenopausal women with receptor-positive early breast cancer. It is unknown whether sequential treatment with tamoxifen and letrozole is superior to letrozole therapy alone. METHODS: In this randomized, phase 3, double-blind trial of the treatment of hormone-receptor-positive breast cancer in postmenopausal women, we randomly assigned women to receive 5 years of tamoxifen monotherapy, 5 years of letrozole monotherapy, or 2 years of treatment with one agent followed by 3 years of treatment with the other. We compared the sequential treatments with letrozole monotherapy among 6182 women and also report a protocol-specified updated analysis of letrozole versus tamoxifen monotherapy in 4922 women. RESULTS: At a median follow-up of 71 months after randomization, disease-free survival was not significantly improved with either sequential treatment as compared with letrozole alone (hazard ratio for tamoxifen followed by letrozole, 1.05; 99% confidence interval [CI], 0.84 to 1.32; hazard ratio for letrozole followed by tamoxifen, 0.96; 99% CI, 0.76 to 1.21). There were more early relapses among women who were assigned to tamoxifen followed by letrozole than among those who were assigned to letrozole alone. The updated analysis of monotherapy showed that there was a nonsignificant difference in overall survival between women assigned to treatment with letrozole and those assigned to treatment with tamoxifen (hazard ratio for letrozole, 0.87; 95% CI, 0.75 to 1.02; P=0.08). The rate of adverse events was as expected on the basis of previous reports of letrozole and tamoxifen therapy. CONCLUSIONS: Among postmenopausal women with endocrine-responsive breast cancer, sequential treatment with letrozole and tamoxifen, as compared with letrozole monotherapy, did not improve disease-free survival. The difference in overall survival with letrozole monotherapy and tamoxifen monotherapy was not statistically significant. (ClinicalTrials.gov number, NCT00004205.)

The bioavailability of bromazepam, omeprazole and paracetamol given by nasogastric feeding tube.

AIMS: To characterize and compare the pharmacokinetic profiles of bromazepam, omeprazole and paracetamol when administered by the oral and nasogastric routes to the same healthy cohort of volunteers. METHODS: In a prospective, monocentric, randomized crossover study, eight healthy volunteers received the three drugs by the oral (OR) and nasogastric routes (NT). Sequential plasma samples were analyzed by high-performance liquid chromatography-UV, pharmacokinetic parameters (Cmax, AUC(0-infinity), t(1/2), k(e), tmax) were compared statistically, and Cmax, AUC(0-infinity) and t(max) were analyzed for bioequivalence. RESULTS: A statistically significant difference was seen in the AUC(0-infinity) of bromazepam, with nasogastric administration decreasing availability by about 25%: AUC(OR) = 2501 ng mL(-1) h; AUC(NT) = 1855 ng mL(-1) h (p < 0.05); ratio (geometric mean) = 0.74 [90% confidence interval (CI) 0.64-0.87]. However, this does not appear to be clinically relevant given the usual dosage range and the drug's half-life (approx. 30 h). A large interindividual variability in omeprazole parameters prevented any statistical conclusion from being drawn in terms of both modes of administration despite their similar average profile: AUC(OR) = 579 ng mL(-1) h; AUC(NT) = 587 ng mL(-1) h (p > 0.05); ratio (geometric mean) = 1.01 (90% CI 0.64-1.61). An extended study with a larger number of subjects may possibly provide clearer answers. The narrow 90% confidence limits of paracetamol indicate bioequivalence: AUC(OR) = 37 microg mL(-1) h; AUC(NT) = 41 microg mL(-1) h(p > 0.05); ratio (geometric mean) = 1.12 (90% CI 0.98-1.28). CONCLUSION: The results of this study show that the nasogastric route of administration does not appear to cause marked, clinically unsuitable alterations in the bioavailability of the tested drugs.

Maladies peptiques [Acid related diseases progress in 2007].

The treatment of reflux disease did not changed. PPI treatment remains the first line treatment and surgery a second line treatment. The effect of surgery in reflux disease reduces and, after ten years, a part of the operated patients needs PPI again. The triple therapy is the treatment of choice of Helicobacter pylori infection. Patients with persistent Helicobacter pylori infection, after a first treatment, should be treated with a sequential treatment. PPI are effective in the prevention of gastroduodenal lesions and in the treatment of dyspeptic symptoms during NSAID treatment. IPP should be given to all patients presenting dyspeptic symptoms under NSAID or COX-2 administration.

Nanopartícul·les core-shell estabilitzades en polímer amb propietats calítiques i bactericides medioambientalment segure

Aquest projecte de doctorat és un treball interdisciplinari adreçat a l’obtenció de nous nanocompòsits (NCs) funcionals sintetitzats a partir de materials polimèrics bescanviadors d’ions que són modificats amb nanopartícules metàl•liques (NPMs) de diferent composició. Els materials desenvolupats s’avaluen en funció de dues possibles aplicacions: 1) com a catalitzadors de reaccions orgàniques d’interès actual (NCs basats en pal•ladi) i, 2) la seva dedicació a aplicacions bactericides en el tractament d’aigües domèstiques o industrials (NCs basats en plata). El desenvolupament de nanomaterials és de gran interès a l’actualitat donades les seves especials propietats, l’aprofitament de les quals és la força impulsora per a la fabricació de nous NCs. Les nanopartícules metàl•liques estabilitzades en polímer (Polymer Stabilized Metal Nanoparticles, PSNPM) s’han preparat mitjançant la tècnica in-situ de síntesi intermatricial (Inter-matrix synthesis, IMS) que consisteix en la càrrega seqüencial dels grups funcionals de les matrius polimèriques amb ions metàl•lics, i la seva posterior reducció química dins de la matriu polimèrica de bescanvi iònic. L’estabilització en matrius polimèriques evita l’agregació entre elles (self-aggreagtion), un dels principals problemes coneguts de les NPs. Pel desenvolupament d’aquesta metodologia, s’han emprat diferents tipus de matrius polimèriques de bescanvi iònic: membrana Sulfonated PolyEtherEtherKetone, SPEEK, així com fibres sintètiques basades en polypropilè amb diferents tipus de grups funcionals, que ens permeten el seu ús com a filtres en la desinfecció de solucions aquoses o com a material catalitzador. Durant el projecte s’ha anat avançant en l’optimització del material nanocomposite final per a les aplicacions d’interès, en quant activitat i funcionalitat de les nanopartícules i estabilitat del nanocomposite. Així, s’ha optimitzat la síntesi de NPs estabilitzades en resines de bescanvi iònic, realitzant un screening de diferents tipus de resines i la seva avaluació en aplicacions industrials d’interès.

Specificity of the rapid rK39 antigen-based immunochromatographic test Kalazar Detect(r) in patients with cutaneous leishmaniasis in Brazil

The aim of this study was to evaluate the specificity of a rapid immunochromatographic test that was developed to detect antibodies against the rK39 antigen for the diagnosis of visceral leishmaniasis (VL). This evaluation was performed using sera from patients with a confirmed diagnosis of active cutaneous leishmaniasis. The sera from 272 patients with a confirmed diagnosis of localised cutaneous leishmaniasis (CL) who resided in an area endemic for Leishmania braziliensis in Brazil were obtained before the initiation of antileishmanial treatment. Kalazar Detect(r)(InBios, Seattle, WA) recombinant K39 antigen-based immunochromatographic strips were used according to the manufacturer's instructions. The test results were evaluated independently by two examiners in sequential order. The positive controls for the test included five serum samples from five patients with parasitologically confirmed diagnosis of VL caused by Leishmania infantum in Brazil. Overall, 100% of the samples obtained from patients with CL were negative, confirming the absence of a serological cross-reaction for individuals with cutaneous disease when these patients were evaluated using the rapid test. The lack of a cross-reaction in patients who were infected by parasites of the same genus highlights the specificity of the rK39 antigen for the diagnosis of VL in areas with the sympatric circulation of L. braziliensis and L. infantum.

Effects of dopamine on total oxygen consumption and oxygen delivery in healthy men.

The effect of acute intravenous dopamine (DA) administration at three sequential (but randomized) infusion rates was studied in eight young male volunteers. DA was infused at 2.5, 5, and 10 micrograms.kg-1.min-1. O2 consumption (VO2) and CO2 production (VCO2) were measured continuously by means of a computerized indirect calorimeter (blood system). In response to the 5- and 10-micrograms.kg-1.min-1 DA infusion rates, a significant increase (P less than 0.01) in VO2 corresponding to a 6% (range, 3-10) and 15% (range, 12-23) increase, respectively, of preinfusion values was observed. In contrast, at the low dose (2.5 micrograms.kg-1.min-1), DA induced no significant change in VO2. Cardiac output (Qc) increased significantly after the three DA administration rates [19% (range, 0-42), 34% (range, 17-71), and 25% (range, -3 to +47)] for the doses 2.5, 5, and 10 micrograms.-kg-1.min-1, respectively. The increase in O2 delivery (QO2) outweighed VO2 at all administration rates despite the relative drop in QO2 at the maximal DA administration rate. These results indicate that in humans DA improves net O2 supply to tissues proportionally more than it increases VO2 at all doses used in the present study.

Response to methylphenidate by adult and pediatric patients with attention-deficit/hyperactivity disorder: the Spanish multicenter DIHANA study.

BACKGROUND The purpose of this multicenter Spanish study was to evaluate the response to immediate-release methylphenidate by children and adults diagnosed with attention-deficit/hyperactivity disorder (ADHD), as well as to obtain information on current therapy patterns and safety characteristics. METHODS This multicenter, observational, retrospective, noninterventional study included 730 patients aged 4-65 years with a diagnosis of ADHD. Information was obtained based on a review of medical records for the years 2002-2006 in sequential order. RESULTS The ADHD predominantly inattentive subtype affected 29.7% of patients, ADHD predominantly hyperactive-impulsive was found in 5.2%, and the combined subtype in 65.1%. Overall, a significant lower Clinical Global Impression (CGI) score and mean number of DSM-IV TR (Diagnostic and Statistical Manual of Mental Disorders Fourth Edition, Text Revision) symptoms by subtype were found after one year of treatment with immediate-release methylphenidate; CGI decreased from 4.51 to 1.69, symptoms of inattention from 7.90 to 4.34, symptoms of hyperactivity from 6.73 to 3.39, and combined subtype symptoms from 14.62 to 7.7. Satisfaction with immediate-release methylphenidate after one year was evaluated as "very satisfied" or "satisfied" by 86.90% of the sample; 25.75% of all patients reported at least one adverse effect. At the end of the study, 41.47% of all the patients treated with immediate-release methylphenidate were still receiving it, with a mean time of 3.80 years on therapy. CONCLUSION Good efficacy and safety results were found for immediate-release methylphenidate in patients with ADHD.

Psychological challenges for the oncology clinician who has to break bad news

Work-related stress of the oncology clinician is not only due to heavy clinical and administrative duties, but also arises when breaking bad news. However, there is important interindividual variation in stress levels during patient encounters, mainly due to the significance the situation represents for the oncologist. A reflection on his own development, his professional identity, and ways of dealing with the patient's suffering can reduce his levels of stress and distress and prevent burnout and other psychiatric disturbances. This chapter summarizes the psychological challenges the oncology clinician is facing when he announces the diagnosis of cancer, deals with the deception of relapse, discusses the transition to palliative care, copes with progression of the disease and uncertainty, and cares for the dying who is facing the unknown. Ways of refiecting on and dealing with these situations from a psychological and communicational perspective are described and illustrated by case vignettes.

Paper de l’ Haemophilus influenzae en les exacerbacions de la Malaltia Pulmonar Obstructiva Crònica (MPOC): tipificació molecular i factors de virulència

Objetivos: 1.-Identificar los factores clínicos y microbiológicos que ayuden a predecir la aparición de exacerbaciones en la EPOC. 2.-Diagnóstico y cuantificación de las especies bacterianas aisladas en esputo (fase de exacerbación y estable) .3.- Tipificación genotípica secuencial de las cepas de H. influenzae y P. aeruginosa. 4.- Impacto del tratamiento antibiótico en la aparición de resistencias en estos patógenos. 5.- Diseño: Estudio prospectivo (3 años). Ámbito del estudio: Hospital Universitario de tercer nivel. Pacientes con EPOC grave atendidos en la Consulta Monográfica de EPOC del Servicio de Neumología. Métodos microbiológicos: Cuantificación de la carga bacteriana en muestras respiratorias en fase estable y en exacerbación. Estudio de la sensibilidad “in vitro”. Tipificación molecular (PFGE y MLST) de H. influenzae y P. aeruginosa. Estudio de los genes de virulencia de H. influenzae mediante PCR. Resultados: Desde Febrero de 2010 a Julio de 2011 se han incluido 77 pacientes. Los microorganismos más frecuentemente aislados en fase de exacerbación fueron: P. aeruginosa (29.3%), H. influenzae (15.92%), M. catarrhalis (12.74%), S. pneumoniae (10.19%) y S. aureus (5.10%). En los 88 episodios por P. aeruginosa se detectaron 38 genotipos diferentes. En los 41 episodios por H. influenzae se detectaron 39 genotipos diferentes. El 10% de los episodios fueron polimicrobianos. Los episodios de EAEPOC y de fase estable tuvieron una distribución de microorganismos similar. Sin embargo, cuando se cuantificaron las cargas bacterianas fueron mayores en EAEPOC (intervalo 4x107 -2x108) que en fase estable (intervalo 2x105 -4x107). Conclusiones: El genotipo de las cepas de P. aeruginosa y H. influenzae aisladas en EAEPOC difieren de un paciente a otro, sin embargo la mayoría de los episodios de cada paciente están causados por un genotipo único.

Antagonistic activity expressed by Shigella sonnei: identification of a putative new bacteriocin

Bacteriocins are antibacterial, proteinaceous substances that mediate microbial dynamics. Bacteriocin production is a highly disseminated property among all major lineages of bacteria, including Shigella. In this paper, we addressed the purification and characterisation of a bacteriocin produced by a Shigella sonnei strain (SS9) isolated from a child with acute diarrhoea. The substance was purified through ammonium-sulphate precipitation and sequential steps of chromatography. The intracellular fraction obtained at 75% ammonium sulphate maintained activity following exposure to pH values from 1-11 and storage at -80ºC for more than two years and was inactivated by high temperatures and proteases. The molecular mass of the purified bacteriocin was determined by mass spectrometry to be 18.56 kDa. The N-terminal sequence of the bacteriocin did not match any other antibacterial proteins described. A putative new bacteriocin produced by S. sonnei has been detected. This bacteriocin may represent a newly described protein or a previously described protein with a newly detected function. Considering that SS9 expresses antagonism against other diarrhoeagenic bacteria, the bacteriocin may contribute to S. sonnei virulence and is potentially applicable to either preventing or controlling diarrhoeal disease.
