"I Felt Like My Life Had Been Given to Me to Start Over": Alice Kaplan's Language Memoir, French Lessons
Alice Kaplan's memoir French Lessons (1993) is a story that deals as much with the issue of language learning as with that of cultural belonging(s). This "language memoir," as it is typical of this sub-genre, is an intimate tale of the transition between languages and cultures. French Lessons recounts her evolving relationship with French language and culture in various phases of her life: starting from childhood, continuing through her graduate student years at Yale and finally as professor of French at Duke. Soon, however, in this unconventional Bildung, the second language turns out to be a verbal safe-house, an instant refuge when her first language and culture happen to be too uncomfortable. Ultimately, French provides a psychic space and a hiding place. Ultimately, however, as Derrida has shown, we are alienated from both the first and the second; we find ourselves to be more comfortable in one than in the other. This essay will analyze such processes with special attention to the part played by the body in Kaplan's building as a student and eventually as a teacher. The analysis will be linked with the text's peculiar narrative style: fast-paced, with simple, concise sentences, nevertheless extremely effective and moving
âHere was no open straightforward planâ: Jumbled Space in âThe Shining Housesâ
This essay discusses the role of place, space and landscape in Alice Munroâs âThe Shining Housesâ, a short story from the collection Dance of the Happy Shades (1968). It takes into consideration the theories of cultural geographers who consider place as a social construct and always in process, in order to illustrate Munroâs skillful treatment of space. In looking at the creation of âplaceâ in the story the essay analyzes the dynamics of being âin-placeâ and of being âout-of-placeâ and their implications in the creation and the definition of what is left outside. In addition, the border between the inside and the outside proves porous and generates eerie transformations
«Yet families are more than gene pools: their stories travel through and map us,too»: Janice Kulyk Keeferâs Honey and Ashes: A Story of Family
Si tratta di un âfamily memoirâ di una scrittrice, poetessa e critico contemporaneo
ucraino-canadese (nata in Canada da genitori ucraini esuli) pubblicato
nel 1988. Il testo ripercorre le dolorose vicende familiari delle passate
generazioni, storie di persecuzioni, di esilio, di patrie e di luoghi nativi perduti,
di famiglie lacerate, divise tra quella che un tempo era lâUcraina e il Canada
contemporaneo. La particolaritĂ di questo testo autobiografico Ăš lâuso
della fotografia, nel caso specifico di foto di famiglia incluse nel testo. Queste
ultime accompagnano il soggetto narrante nel suo tentativo di ricostruire
unâidentitĂ familiare ed un âsogno di appartenenzaâ che perĂČ sembrano
continuamente sottrarsi e sfuggire alla comprensione dellâio narrante ed a
definizioni precostituit
Strategies for identity : the fiction of Margaret Atwood
This study is a critical reading of the fiction of contemporary Canadian novelist and poet Margaret Atwood. My analysis focuses on problems pertaining to the questions of genre, identity and female subjectivity. The thesis is thematically structured. Chapter One, 'The Question of Genre: Creative Re- Appropriations, explores the plurality of genres and narrative styles present in the novels. The second Chapter' A Proliferation of Identities: Doubling and Intertextuality' examines constructions of the self in the light of psychoanalytic theories of language and subjectivity which conceive of the subject as heterogeneous and in constant process. Atwood's challenge to the notion of the homogeneous ego finds a gendered vision wherein woman assumes a multiplicity of roles and positions. Chapter Three 'Cognitive Questions' discusses the text's emphasis on sense receptivity and the epistemological question they pose in relation to language, reality and interpretation. Chapter Four 'Writing the Female Character' analyses Atwood's configurations of femininity, sexual politics and sexual difference
A soil fungus confers plant resistance against a phytophagous insect by disrupting the symbiotic role of its gut microbiota
Plants generate energy flows through natural food webs, driven by competition for resources among organisms, which are part of a complex network of multitrophic interactions. Here, we demonstrate that the interaction between tomato plants and a phytophagous insect is driven by a hidden interplay between their respective microbiotas. Tomato plants colonized by the soil fungus Trichoderma afroharzianum, a beneficial microorganism widely used in agriculture as a biocontrol agent, negatively affects the development and survival of the lepidopteran pest Spodoptera littoralis by altering the larval gut microbiota and its nutritional support to the host. Indeed, experiments aimed to restore the functional microbial community in the gut allow a complete rescue. Our results shed light on a novel role played by a soil microorganism in the modulation of plant-insect interaction, setting the stage for a more comprehensive analysis of the impact that biocontrol agents may have on ecological sustainability of agricultural systems
Recurrence of Primary Sclerosing Cholangitis After Liver Transplant in Children : An International Observational Study
Background and Aims Recurrent primary sclerosing cholangitis (rPSC) following liver transplant (LT) has a negative impact on graft and patient survival; little is known about risk factors for rPSC or disease course in children. Approach and Results We retrospectively evaluated risk factors for rPSC in 140 children from the Pediatric PSC Consortium, a multicenter international registry. Recipients underwent LT for PSC and had >90 days of follow-up. The primary outcome, rPSC, was defined using Graziadei criteria. Median follow-up after LT was 3 years (interquartile range 1.1-6.1). rPSC occurred in 36 children, representing 10% and 27% of the subjects at 2 years and 5 years following LT, respectively. Subjects with rPSC were younger at LT (12.9 vs. 16.2 years), had faster progression from PSC diagnosis to LT (2.5 vs. 4.1 years), and had higher alanine aminotransferase (112 vs. 66 IU/L) at LT (all P < 0.01). Inflammatory bowel disease was more prevalent in the rPSC group (86% vs. 66%; P = 0.025). After LT, rPSC subjects had more episodes of biopsy-proved acute rejection (mean 3 vs. 1; P < 0.001), and higher prevalence of steroid-refractory rejection (41% vs. 20%; P = 0.04). In those with rPSC, 43% developed complications of portal hypertension, were relisted for LT, or died within 2 years of the diagnosis. Mortality was higher in the rPSC group (11.1% vs. 2.9%; P = 0.05). Conclusions The incidence of rPSC in this cohort was higher than previously reported, and was associated with increased morbidity and mortality. Patients with rPSC appeared to have a more aggressive, immune-reactive phenotype. These findings underscore the need to understand the immune mechanisms of rPSC, to lay the foundation for developing new therapies and improve outcomes in this challenging population.Peer reviewe

Catestatin Improves Post-Ischemic Left Ventricular Function and Decreases Ischemia/Reperfusion Injury in Heart
The Chromogranin A (CgA)-derived anti-hypertensive peptide catestatin (CST) antagonizes catecholamine secretion, and is a negative myocardial inotrope acting via a nitric oxide-dependent mechanism. It is not known whether CST contributes to ischemia/reperfusion injury or is a component of a cardioprotective response to limit injury. Here, we tested whether CST by virtue of its negative inotropic activity improves post-ischemic cardiac function and cardiomyocyte survival. Three groups of isolated perfused hearts from adult Wistar rats underwent 30-min ischemia and 120-min reperfusion (I/R, Group 1), or were post-conditioned by brief ischemic episodes (PostC, 5-cycles of 10-s I/R at the beginning of 120-min reperfusion, Group 2), or with exogenous CST (75 nM for 20 min, CST-Post, Group-3) at the onset of reperfusion. Perfusion pressure and left ventricular pressure (LVP) were monitored. Infarct size was evaluated with nitroblue-tetrazolium staining. The CST (5 nM) effects were also tested in simulated ischemia/reperfusion experiments on cardiomyocytes isolated from young-adult rats, evaluating cell survival with propidium iodide labeling. Infarct size was 61 ± 6% of risk area in hearts subjected to I/R only. PostC reduced infarct size to 34 ± 5%. Infarct size in CST-Post was 36 ± 3% of risk area (P < 0.05 respect to I/R). CST-Post reduced post-ischemic rise of diastolic LVP, an index of contracture, and significantly improved post-ischemic recovery of developed LVP. In isolated cardiomyocytes, CST increased the cell viability rate by about 65% after simulated ischemia/reperfusion. These results suggest a novel cardioprotective role for CST, which appears mainly due to a direct reduction of post-ischemic myocardial damages and dysfunction, rather than to an involvement of adrenergic terminals and/or endothelium
Quantifying risks and interventions that have affected the burden of diarrhoea among children younger than 5 years : an analysis of the Global Burden of Disease Study 2017
Background Many countries have shown marked declines in diarrhoea! disease mortality among children younger than 5 years. With this analysis, we provide updated results on diarrhoeal disease mortality among children younger than 5 years from the Global Burden of Diseases, Injuries, and Risk Factors Study 2017 (GBD 2017) and use the study's comparative risk assessment to quantify trends and effects of risk factors, interventions, and broader sociodemographic development on mortality changes in 195 countries and territories from 1990 to 2017.
Methods This analysis for GBD 2017 had three main components. Diarrhoea mortality was modelled using vital registration data, demographic surveillance data, and verbal autopsy data in a predictive, Bayesian, ensemble modelling tool; and the attribution of risk factors and interventions for diarrhoea were modelled in a counterfactual framework that combines modelled population-level prevalence of the exposure to each risk or intervention with the relative risk of diarrhoea given exposure to that factor. We assessed the relative and absolute change in diarrhoea mortality rate between 1990 and 2017, and used the change in risk factor exposure and sociodemographic status to explain differences in the trends of diarrhoea mortality among children younger than 5 years.
Findings Diarrhoea was responsible for an estimated 533 768 deaths (95% uncertainty interval 477 162-593 145) among children younger than 5 years globally in 2017, a rate of 78.4 deaths (70.1-87.1) per 100 000 children. The diarrhoea mortality rate ranged between countries by over 685 deaths per 100 000 children. Diarrhoea mortality per 100 000 globally decreased by 69.6% (63.1-74.6) between 1990 and 2017. Among the risk factors considered in this study, those responsible for the largest declines in the diarrhoea mortality rate were reduction in exposure to unsafe sanitation (13.3% decrease, 11.2-15.5), childhood wasting (9.9% decrease, 9.6-10.2), and low use of oral rehydration solution (6.9% decrease, 4-8-8-4).
Interpretation Diarrhoea mortality has declined substantially since 1990, although there are variations by country. Improvements in sociodemographic indicators might explain some of these trends, but changes in exposure to risk factors-particularly unsafe sanitation, childhood growth failure, and low use of oral rehydration solution-appear to be related to the relative and absolute rates of decline in diarrhoea mortality. Although the most effective interventions might vary by country or region, identifying and scaling up the interventions aimed at preventing and protecting against diarrhoea that have already reduced diarrhoea mortality could further avert many thousands of deaths due to this illness
