“War Worlds” reads twentieth-century British and Anglophone literature to examine the social practices of marginal groups (pacifists, strangers, traitors, anticolonial rebels, queer soldiers) during the world wars. This dissertation shows that these diverse “enemies within” England and its colonies—those often deemed expendable for, but nonetheless threatening to, British state and imperial projects—provided writers with alternative visions of collective life in periods of escalated violence and social control. By focusing on the social and political activities of those who were not loyal citizens or productive laborers within the British Empire, “War Worlds” foregrounds the small group, a form of collectivity frequently portrayed in the literature of the war years but typically overlooked in literary critical studies. I argue that this shift of focus from grand politics to small groups not only illuminates surprising social fissures within England and its colonies but provides a new vantage from which to view twentieth-century experiments in literary form.

This study argues that Chaucer's poetry belongs to a far-reaching conversation about the forms of consolation (philosophical, theological, and poetic) that are available to human persons. Chaucer's entry point to this conversation was Boethius's Consolation of Philosophy, a sixth-century dialogue that tried to show how the Stoic ideals of autonomy and self-possession are not simply normative for human beings but remain within the grasp of every individual. Drawing on biblical commentary, consolation literature, and political theory, this study contends that Chaucer's interrogation of the moral and intellectual ideals of the Consolation took the form of philosophical disconsolations: scenes of profound poetic rupture in which a character, sometimes even Chaucer himself, turns to philosophy for solace and yet fails to be consoled. Indeed, philosophy itself becomes a source of despair. In staging these disconsolations, I contend that Chaucer asks his readers to consider the moral dimensions of the aspirations internal to ancient philosophy and the assumptions about the self that must be true if its insights are to console and instruct. For Chaucer, the self must be seen as a gift that flowers through reciprocity (both human and divine) and not as an object to be disciplined and regulated.
Chapter one focuses on the Consolation of Philosophy. I argue that recent attempts to characterize Chaucer's relationship to this text as skeptical fail to engage the Consolation on its own terms. The allegory of Lady Philosophy's revelation to a disconsolate Boethius enables philosophy to become both an agent and an object of inquiry. I argue that Boethius's initial skepticism about the pretentions of philosophy is in part what Philosophy's therapies are meant to respond to. The pressures that Chaucer's poetry exerts on the ideals of autonomy and self-possession sharpen one of the major absences of the Consolation: viz., the unanswered question of whether Philosophy's therapies have actually consoled Boethius. Chapter two considers one of the Consolation's fascinating and paradoxical afterlives: Robert Holcot's Postilla super librum sapientiae (1340-43). I argue that Holcot's Stoic conception of wisdom, a conception he explicitly links with Boethius's Consolation, relies on a model of agency that is strikingly similar to the powers of self-knowledge that Philosophy argues Boethius to posses. Chapter three examines Chaucer's fullest exploration of the Boethian model of selfhood and his ultimate rejection of it in Troilus and Criseyde. The poem, which Chaucer called his "tragedy," belonged to a genre of classical writing he knew of only from Philosophy's brief mention of it in the Consolation. Chaucer appropriates the genre to explore and recover mourning as a meaningful act. In Chapter four, I turn to Dante and the House of Fame to consider Chaucer's self-reflections about his ambitions as a poet and the demands of truth-telling.

Chronic telogen effluvium (CTE), a poorly understood condition, can be confused with or may be a prodrome to female pattern hair loss (FPHL). The pathogenesis of both is related to follicle cycle shortening and possibly to blood supply changes. To analyze a number of histomorphometric and immunohistochemical findings through vascular endothelial growth factor (VEGF), Ki-67, and CD31 immunostaining in scalp biopsies of 20 patients with CTE, 17 patients with mild FPHL and 9 controls. Ki-67 index and VEGF optical density were analyzed at the follicular outer sheath using ImageJ software. CD31 microvessel density was assessed by a Chalkley grid. Significant follicle miniaturization and higher density of nonanagen follicles were found in FPHL, compared with patients with CTE and controls. Ki-67+ index correlated positively with FPHL histological features. The FPHL group showed the highest VEGF optical density, followed by the CTE and control groups. No differences were found in CD31 microvessel density between the three groups. Histomorphometric results establish CTE as a distinct disorder, separate from FPHL from its outset. Its pathogenic mechanisms are also distinct. These findings support the proposed mechanism of 'immediate telogen release' for CTE, leading to cycle synchronization. For FPHL, accelerated anagen follicular mitotic rates and, thus, higher Ki-67 and VEGF values, would leave less time for differentiation, resulting in hair miniaturization.

An HPLC-PAD method using a gold working electrode and a triple-potential waveform was developed for the simultaneous determination of streptomycin and dihydrostreptomycin in veterinary drugs. Glucose was used as the internal standard, and the triple-potential waveform was optimized using a factorial and a central composite design. The optimum potentials were as follows: amperometric detection, E1=-0.15V; cleaning potential, E2=+0.85V; and reactivation of the electrode surface, E3=-0.65V. For the separation of the aminoglycosides and the internal standard of glucose, a CarboPac™ PA1 anion exchange column was used together with a mobile phase consisting of a 0.070 mol L(-1) sodium hydroxide solution in the isocratic elution mode with a flow rate of 0.8 mL min(-1). The method was validated and applied to the determination of streptomycin and dihydrostreptomycin in veterinary formulations (injection, suspension and ointment) without any previous sample pretreatment, except for the ointments, for which a liquid-liquid extraction was required before HPLC-PAD analysis. The method showed adequate selectivity, with an accuracy of 98-107% and a precision of less than 3.9%.

Interleukin-22 (IL-22) is a class 2 cytokine whose primary structure is similar to that of interleukin 10 (IL-10) and interferon-gamma (IFN-gamma). IL-22 induction during acute phase immune response indicates its involvement in mechanisms of inflammation. Structurally different from IL-10 and a number of other members of IL-10 family, which form intertwined inseparable V-shaped dimers of two identical polypeptide chains, a single polypeptide chain of IL-22 folds on itself in a relatively globular structure. Here we present evidence, based on native gel electrophoresis, glutaraldehyde cross-linking, dynamic light scattering, and small angle x-ray scattering experiments, that human IL-22 forms dimers and tetramers in solution under protein concentrations assessable by these experiments. Unexpectedly, low-resolution molecular shape of IL-22 dimers is strikingly similar to that of IL-10 and other intertwined cytokine dimeric forms. Furthermore, we determine an ab initio molecular shape of the IL-22/IL-22R1 complex which reveals the V-shaped IL-22 dimer interacting with two cognate IL-22R1 molecules. Based on this collective evidence, we argue that dimerization might be a common mechanism of all class 2 cytokines for the molecular recognition with their respective membrane receptor. We also speculate that the IL-22 tetramer formation could represent a way to store the cytokine in nonactive form at high concentrations that could be readily converted into functionally active monomers and dimers upon interaction with the cognate cellular receptors.

The alkyl chain of anatoxin-a(s) (cyclic guanidines), which can be used as an intermediate in the total synthesis of anatoxin-a(s), was synthesized in both racemic and enantiomerically pure forms. These enantiomerically pure cyclic compounds can be used as chiral inductors in some reactions. The two racemic routes disclosed herein have the advantages of high overall yield and mild reaction conditions. Both routes proceed through an intermediate 2,3-diaminoacid - an important synthetic scaffold - with good yields. Furthermore, the N,N-dimethyl-2(tosylimino)imidazolidine-4-carboxamide might be obtained from 2-(tosylimino)imidazolidine-4-carboxylic acid followed by selective reduction of the carbonyl functionality. All synthesized compounds were analyzed by mass spectrometry and (1)H NMR and (13)C NMR spectroscopy.

Dendritic cells (DCs) have been described as initiators and modulators of the immune response. Recently we have shown a predominant production of interleukin-10 cytokine, low levels of interferon-gamma and inefficient T cell proliferation in patients with severe forms of chromoblastomycosis. Chromoblastomycosis starts with subcutaneous inoculation of Fonsecaea pedrosoi into tissue where DCs are the first line of defence against this microorganism. In the present study, the interaction of F. pedrosoi and DCs obtained from patients with chromoblastomycosis was investigated. Our results showed that DCs from patients exhibited an increased expression of human leucocyte antigen D-related (HLA-DR) and co-stimulatory molecules. In the presence of conidia, the expression of HLA-DR and CD86 was up-regulated by DCs from patients and controls. Finally, we demonstrate the reversal of antigen-specific anergy and a T helper type 1 response mediated by DCs incubated with F. pedrosoi conidea.

Coastal Photograph by Hubert Chanson This photograph of standing wave bed forms was taken at very low tide. The tidal range was 10 m. The bed forms were located on the island of Le Verdelet, in a channel between Le Grande Jaune and Le Verdelet. It is likely that these standing wave bed forms were formed during transcritical shallow water flows at the end of ebb tide. The author’s watch is in the foreground for scale.

Considerable resources have been expended promoting hedgerow intercropping with shrub legumes to farmers in the Philippine uplands. Despite the resources committed to research and extension, persistent adoption by farmers has been limited to low cost versions of the technology including natural vegetation and grass strips. In this paper, cost-benefit analysis is used to compare the economic returns from traditional open-field maize farming with returns from intercropping maize between leguminous shrub hedgerows, natural vegetation strips and grass strips. An erosion/productivity model, Soil Changes Under Agroforestry, was used to predict the effect of erosion on maize yields. Key informant surveys with experienced maize farmers were used to derive production budgets for the alternative farming methods. The economic incentives revealed by the cost-benefit analysis help to explain the adoption of maize farming methods in the Philippine uplands. Open-field farming without hedgerows has been by far the most popular method of maize production, often with two or more fields cropped in rotation. There is little persistent adoption of hedgerow intercropping with shrub legumes because sustained maize yields are not realised rapidly enough to compensate farmers for establishment and maintenance costs. Natural vegetation and grass strips are more attractive to farmers because of lower establishment costs, and provide intermediate steps to adoption. Rural finance, commodity pricing and agrarian reform policies influence the incentives for maize farmers in the Philippine uplands to adopt and maintain hedgerow intercropping.
