Alasdair Gray`s 1982 Janine (1984): a postmodernist scottish novel

Alasdair Gray is now an established figure in the Scottish literary scene and has numerous claims to be considered an important voice writing in English. First Lanark: A Life in Four Books (1981) and then 1982 Janine (1984) contributed to the recognition of Gray as one of the founding fathers of the new Scottish writing and as a figure of importance in international contemporary fiction due to his innovative, experimental and postmodernist novels. As the title of this dissertation - “Alasdair Gray’s 1982 Janine (1984): A Postmodernist Scottish Novel” - suggests, it aims at analysing the author’s second novel, 1982 Janine (1984), in a thematic and formal perspective, in order to justify the choice of the terms - Postmodernist and Scottish - to classify this novel. 1982 Janine projects a world through Jock McLeish’s mind and is a powerful stream-of-consciousness narrative. Jock is an alcoholic who lives a personal crisis and, therefore, tries to escape from his depressing reality through sexual fantasies and political diatribes. During a single night in a Scottish hotel room, he drinks and dreams, and spends the whole night alone with his fantasies and fears, his memories and hopes. In Chapter 11, the most daring experimental section of the novel, Jock attempts to commit suicide by taking an overdose of tablets with alcohol but fails. Following this, he decides to review his life and make for a new beginning; the novel thus closing with an optimistic note. Also, the narrative is based on a constant interweaving of sex fantasy with political satire, that is, it is through his protagonist that Gray manages to convey the state of Scotland as well as the concerns and aspirations of the Scottish people and then, proceed to a political and social critique. This dissertation appears structured in three chapters. In Chapter I - “Alasdair Gray: A Postmodernist Scottish Writer” - I present Gray as a powerful postmodernist writer who also sees himself as a Scottish author, and more particularly as a Glaswegian, who concentrates on Scottish subject matter in his literary work. In a first section, I offer a brief survey of the Scottish literary scene from the fourteenth to the twentieth century, in order to understand Gray’s choice of setting and themes and to check his influence or indebtedness to previous Scottish authors. As 1982 Janine is also a good example of selfconscious experimental writing, in a second section, I present various seminal fictional works that introduced and developed experimentalism in British fiction, in order to evaluate the influence of modernist developments in form and technique on recent experimental writing. The third section consists of an introduction to Gray’s work for he is not only a novelist, but also an artist, a playwright, a poet, an activist and a scholar. Chapter II - “Postmodernist Features in 1982 Janine” - aims at listing and examining the postmodernist devices that the novel includes, in what content and form are concerned. On the one hand, the use of a developed type of the modernist stream of consciousness, the presence of a protagonist who feels entrapped in a specific system, the quest for freedom, the incoherence and fragmentation of time, the nonchronological order of the narrative, the blending of fantasy and “reality”, as well as the importance of the Scottish material are definitely current aspects within postmodernist literature that can be found in Gray’s novel. On the other hand, the handling of literary self-conscious devices, such as typographical experimentation, presence of metafiction and intertextuality, and inclusion of an Epilogue, are likewise among recurrent postmodernist features. As the title - “A Narratological Analysis of 1982 Janine” - evidences, Chapter III offers a description of the mechanics of the narrative and its functioning in order to better understand the narrative technique of postmodernist fiction. This study is based primarily on Gérard Genette’s theoretical framework and terminology, presented in Narrative Discourse: An Essay in Method, an analytical tool that allows me to provide a more objective and scientific analysis. Hence, I follow the Genettian division of narrative discourse in Time, Mood and Voice while examining the novel. Finally, I proceed to a description of the intertextual relationships 1982 Janine establishes with other texts.

Development of a novel microextraction by packed sorbent-based approach followed by ultrahigh pressure liquid chromatography as a powerful technique for quantification phenolic constituents of biological interest in wines

A novel analytical approach, based on a miniaturized extraction technique, the microextraction by packed sorbent (MEPS), followed by ultrahigh pressure liquid chromatography (UHPLC) separation combined with a photodiode array (PDA) detection, has been developed and validated for the quantitative determination of sixteen biologically active phenolic constituents of wine. In addition to performing routine experiments to establish the validity of the assay to internationally accepted criteria (linearity, sensitivity, selectivity, precision, accuracy), experiments are included to assess the effect of the important experimental parameters on the MEPS performance such as the type of sorbent material (C2, C8, C18, SIL, and M1), number of extraction cycles (extract-discard), elution volume, sample volume, and ethanol content, were studied. The optimal conditions of MEPS extraction were obtained using C8 sorbent and small sample volumes (250 μL) in five extraction cycle and in a short time period (about 5 min for the entire sample preparation step). The wine bioactive phenolics were eluted by 250 μL of the mixture containing 95% methanol and 5% water, and the separation was carried out on a HSS T3 analytical column (100 mm × 2.1 mm, 1.8 μm particle size) using a binary mobile phase composed of aqueous 0.1% formic acid (eluent A) and methanol (eluent B) in the gradient elution mode (10 min of total analysis). The method gave satisfactory results in terms of linearity with r2-values > 0.9986 within the established concentration range. The LOD varied from 85 ng mL−1 (ferulic acid) to 0.32 μg mL−1 ((+)-catechin), whereas the LOQ values from 0.028 μg mL−1 (ferulic acid) to 1.08 μg mL−1 ((+)-catechin). Typical recoveries ranged between 81.1 and 99.6% for red wines and between 77.1 and 99.3% for white wines, with relative standard deviations (RSD) no larger than 10%. The extraction yields of the MEPSC8/UHPLC–PDA methodology were found between 78.1 (syringic acid) and 99.6% (o-coumaric acid) for red wines and between 76.2 and 99.1% for white wines. The inter-day precision, expressed as the relative standard deviation (RSD%), varied between 0.2% (p-coumaric and o-coumaric acids) and 7.5% (gentisic acid) while the intra-day precision between 0.2% (o-coumaric and cinnamic acids) and 4.7% (gallic acid and (−)-epicatechin). On the basis of analytical validation, it is shown that the MEPSC8/UHPLC–PDA methodology proves to be an improved, reliable, and ultra-fast approach for wine bioactive phenolics analysis, because of its capability for determining simultaneously in a single chromatographic run several bioactive metabolites with high sensitivity, selectivity and resolving power within only 10 min. Preliminary studies have been carried out on 34 real whole wine samples, in order to assess the performance of the described procedure. The new approach offers decreased sample preparation and analysis time, and moreover is cheaper, more environmentally friendly and easier to perform as compared to traditional methodologies.

Use of novel biomarkers (Homocysteine, vitamin B6, B9 and B12) on the assessing the progression of cardiovascular disease

A large number of evidences correlate elevated levels of homocysteine (Hcys) with a higher cardiovascular diseases (CVDs) risk, especially, atherosclerosis. Similarly, abnormal low levels of the vitamins B6, B9 and B12 are associated to an instability in the methionine cycle with an over production of Hcys. Thus, biomedical sciences are looking forward for a cheaper, faster, precise and accurate analytical methodology to quantify these compounds in a suitable format for the clinical environment. Therefore the objective of this study was the development of a simple, inexpensive and appropriate methodology to use at the clinical level. To achieve this goal, a procedure integrating a digitally controlled (eVol®) microextraction by packed sorbent (MEPS) and an ultra performance liquid chromatography (UPLC) coupled to a photodiode array detector (PDA) was developed to identify and quantify Hcys vitamins B6, B9 and B12. Although different conditions were assayed, we were not able to combine Hcys with the vitamins in the same analytical procedure, and so we proceeded to the optimization of two methods differing only in the composition of the gradient of the mobile phase and the injected volume. It was found that MEPS did not bring any benefit to the quantification of the Hcys in the plasma. Therefore, we developed and validate an alternative method that uses the direct injection of treated plasma (reduced and precipitated). This same method was evaluated in terms of selectivity, linearity, limit of detection (LOD), limit of quantification (LOQ), matrix effect and precision (intra-and inter-day) and applied to the determination of Hcys in a group composed by patients presenting augmented CVD risk. Good results in terms of selectivity and linearity (R2> 0.9968) were obtained, being the values of LOD and LOQ 0.007 and 0.21 mol / L, respectively. The intra-day precision (1.23-3.32%), inter-day precision (5.43-6.99%) and the recovery rate (82.5 to 93.1%) of this method were satisfactory. The matrix effect (>120%) was, however, higher than we were waiting for. Using this methodology it was possible to determine the amount of Hcys in real plasma samples from individuals presenting augmented CVD risk. Regarding the methodology developed for vitamins, despite the optimization of the extraction technique and the chromatographic conditions, it was found that the levels usually present in plasma are far below the sensitivity we obtained. Therefore, further optimizations of the methodology developed are needed. As conclusion, part of the objectives of this study was achieved with the development of a quick, simple and cheaper method for the quantification of Hcys.
