Grandiflora : Recent Paintings by Daniel Mafe

Grandiflora: Recent Paintings by Daniel Mafe The paintings of Grandiflora are improvised around a range of different flower motifs culled from medieval textiles and botanical illustrations. Each of the paintings is constructed upon a ground of flat, palely luminous yellow occasionally supplemented by additional areas of high-keyed pastel. Pink, blue, green and mauve together with the yellow, generate a shimmering and even incandescent glow. The graphic images of the flowers with the flat colour areas are then contrasted and worked over with richly sensual, abstract gestures of paint. Within the work there is a pronounced almost rococo-esque opticality as it operates between these different visual codes of flat colour, recognizable floral forms, and gesture. These codes combine to produce a definite visceral impact on the viewer, a pronounced and tactile sense of the experience and ambiguity inherent in perceiving. This ambiguity is interestingly at odds with the apparently clean and crisp quality each painting demonstrates as an integrated whole. Indeed each piece goes on to reveal, despite the use of overt figurative quotations, a sense of the purely abstract which in its turn concretely establishes the ornamental.

Biochemical profiling of proteins and metabolites in wound exudate from chronic wound environments

The lack of fundamental knowledge on the biological processes associated with wound healing represents a significant challenge. Understanding the biochemical changes that occur within a chronic wound could provide insights into the wound environment and enable more effective wound management. We report on the stability of wound fluid samples under various conditions and describe a high-throughput approach to investigate the altered biochemical state within wound samples collected from various types of chronic, ulcerated wounds. Furthermore, we discuss the viability of this approach in the early stages of wound sample protein and metabolite profiling and subsequent biomarker discovery. This approach will facilitate the detection of factors that may correlate with wound severity and/or could be used to monitor the response to a particular treatment.

Sex-based comparisons of myofibrillar protein synthesis after resistance exercise in the fed state

Sex-based comparisons of myofibrillar protein synthesis after resistance exercise in the fed state. J Appl Physiol 112: 1805-1813, 2012. First published March 1, 2012; doi:10.1152/japplphysiol.00170.2012.- We made sex-based comparisons of rates of myofibrillar protein synthesis (MPS) and anabolic signaling after a single bout of high-intensity resistance exercise. Eight men (20 ± 10 yr, BMI = 24.3 ± 2.4) and eight women (22 ± 1.8 yr, BMI = 23.0 ± 1.9) underwent primed constant infusions of L-[ring-13C6]phenylalanine on consecutive days with serial muscle biopsies. Biopsies were taken from the vastus lateralis at rest and 1, 3, 5, 24, 26, and 28 h after exercise. Twenty-five grams of whey protein was ingested immediately and 26 h after exercise. We also measured exercise-induced serum testosterone because it is purported to contribute to increases in myofibrillar protein synthesis (MPS) postexercise and its absence has been hypothesized to attenuate adaptative responses to resistance exercise in women. The exercise-induced area under the testosterone curve was 45-fold greater in men than women in the early (1 h) recovery period following exercise (P < 0.001). MPS was elevated similarly in men and women (2.3- and 2.7-fold, respectively) 1-5 h postexercise and after protein ingestion following 24 h recovery. Phosphorylation of mTORSer2448 was elevated to a greater extent in men than women acutely after exercise (P = 0.003), whereas increased phosphorylation of p70S6K1Thr389 was not different between sexes. Androgen receptor content was greater in men (main effect for sex, P = 0.049). Atrogin-1 mRNA abundance was decreased after 5 h recovery in both men and women (P < 0.001), and MuRF-1 expression was elevated in men after protein ingestion following 24 h recovery (P = 0.003). These results demonstrate minor sex-based differences in signaling responses and no difference in the MPS response to resistance exercise in the fed state. Interestingly, our data demonstrate that exerciseinduced increases in MPS are dissociated from postexercise testosteronemia and that stimulation of MPS occurs effectively with low systemic testosterone concentrations in women.

Provisional matrix deposition in hemostasis and venous insufficiency: Tissue preconditioning for nonhealing venous ulcers

Significance: Chronic wounds represent a major burden on global healthcare systems and reduce the quality of life of those affected. Significant advances have been made in our understanding of the biochemistry of wound healing progression. However, knowledge regarding the specific molecular processes influencing chronic wound formation and persistence remains limited. Recent Advances: Generally, healing of acute wounds begins with hemostasis and the deposition of a plasma-derived provisional matrix into the wound. The deposition of plasma matrix proteins is known to occur around the microvasculature of the lower limb as a result of venous insufficiency. This appears to alter limb cutaneous tissue physiology and consequently drives the tissue into a ‘preconditioned’ state that negatively influences the response to wounding. Critical Issues: Processes, such as oxygen and nutrient suppression, edema, inflammatory cell trapping/extravasation, diffuse inflammation, and tissue necrosis are thought to contribute to the advent of a chronic wound. Healing of the wound then becomes difficult in the context of an internally injured limb. Thus, interventions and therapies for promoting healing of the limb is a growing area of interest. For venous ulcers, treatment using compression bandaging encourages venous return and improves healing processes within the limb, critically however, once treatment concludes ulcers often reoccur. Future Directions: Improved understanding of the composition and role of pericapillary matrix deposits in facilitating internal limb injury and subsequent development of chronic wounds will be critical for informing and enhancing current best practice therapies and preventative action in the wound care field.

Disabled Revolutionary War Veterans and the Construction of Disability in the Early United States, c. 1776-1840

This thesis addresses the following broad research question: what did it mean to be a disabled Revolutionary War veteran in the early United States during the period from 1776 to roughly 1840? The study approaches the question from two angles: a state-centred one and an experiential one. In both cases, the theoretical framework employed comes from disability studies. Consequently, disability is regarded as a sociocultural phenomenon rather than a medical condition. The state-centred dimension of the study explores the meaning of disability and disabled veterans to the early American state through an examination of the major military pension laws of the period. An analysis of this legislation, particularly the invalid pension acts of 1793 and 1806, indicates that the early United States represents a key period in the development of the modern disability category. The experiential approach, in contrast, shifts the focus of attention away from the state towards the lived experiences of disabled veterans. It seeks to address the issue of whether or not the disabilities of disabled veterans had any significant material impact on their everyday lives. It does this through a comparison of the situation of 153 disabled veterans with that of an equivalent number of nondisabled veterans. The former group received invalid pensions while the latter did not. In comparing the material conditions of disabled and nondisabled veterans, a wide range of primary sources from military records to memoirs and letters are used. The most important sources in this regard are the pension application papers submitted by veterans in the early nineteenth century. These provide us with a unique insight into the everyday lives of veterans. Looking at the issue of experience through the window of the pension files reveals that there was not much difference in the broad contours of disabled and nondisabled veteran life. This finding has implications for the theorisation of disability that are highlighted and discussed in the thesis. The main themes covered in this study are: the wartime experiences of injured American soldiers, the military pension establishment of the early United States and the legal construction of disability, and the post-war working and family lives of disabled veterans. Keywords: disability, early America, veterans, military pensions, disabled people, Revolutionary War, United States, disability theory.

Tuuleen piirrän nimeni : Daniel Urwindin fragmentaarinen omaelämäkerta Bo Carpelanin romaanissa Alkutuuli

Tutkielma käsittelee Bo Carpelanin romaania Alkutuuli (Urwind 1993) päähenkilö Daniel Urwindin fragmentaarisesti kerrottuna elämäntarinana. Kyse on kahdella aikatasolla etenevästä fiktiivisestä omaelämäkerrasta, joka perustuu viikottaisiin päiväkirjamerkintöihin. Daniel hahmottaa identiteettiään tilaan kytkeytyneiden muistojen sekä oman nimensä avulla leikaten samalla kerronnan jatkuvuuden. Tutkimusongelmana on hahmottaa Danielin kerronnan tavat, kirjoittamisen syyt sekä prosessiin lopputulos. Menneisyyteen kohdistuvan minä-kerronnan analyysi perustuu Dorrit Cohnin Transparent minds -teoksen käsitteistöön. Alkutuulessa esiintyy muistikerronnan ja muistimonologin epäsäännöllistä vuorottelua. Niiden osana on edesmenneiden läheisten upotettuja monologeja, joiden takaa kuultaa Danielin ääni: monologit ovat Danielin kuvittelemia tai referoimia puheita ja ajatuksia, joiden esittäjä on hänen yksinäisen keskustelunsa toinen osapuoli. Omaelämäkertaa käsittelevinä teoreettisina lähteinä ovat ensisijaisesti Päivi Kososen artikkelit sekä hänen tutkimuksensa Elämät sanoissa. Tutkielman tulkinnan kannalta keskeisessä asemassa ovat Bo Carpelanin essee- ja kaunokirjallinen tuotanto. Kirjoittamisen lähtökohtana on päähenkilön identiteettiä horjuttava elämänvaihe. Vaimo Marian lähdettyä vuodeksi Amerikkaan Daniel pyrkii löytämään oman kielensä ja luomaan muistojensa avulla eheämmän kuvan itsestään. Prosessiin kytkeytyy keskeisesti tila - Danielin kulkiessa talossaan, joka on hänen lapsuudenkotinsa, aistitodellisuus toimii mieleenpalauttajana: äänet ja tuoksut johdattavat hänet elämään menneisyyden muistoja uudelleen nykyhetkessä. Samalla talo ja huoneet personifioituvat ja minuus alkaa rakentua tilan kaltaiseksi. Uusien ovien ja huoneiden löytyminen symboloi Danielin muistojen selkeytymistä ja itseymmärryksen syvenemistä. Kirjoittamisen voi tulkita olevan psykoanalyyttinen prosessi, jossa omaelämäkerran minä keskustelee menneisyyden minänsä kanssa. Puhuja odottaa vastausta toiselta, vaikka vastaus löytyy paradoksaalisesti itsestä. Omaelämäkerran moniäänisyyttä korostavat edesmenneiden läheisten läsnäolo, Danielin eri ikävaiheiden identiteetit ja kaksoisolentojen hahmoissa esiintyvät minuudet. Kirjoittamisen avulla Daniel pyrkii pääsemään etäämmälle itsestään ja saavuttamaan minättömyyden tilan, jota käsitellään John Keatsilta peräisin olevan käsitteen "negatiivinen kyky" avulla. Alkutuuli on taiteilijaromaani, jossa taiteilijuutta edustavat siivet ja lentäminen kytkeytyvät mielikuvitukseen ja uusiutumiseen. Danielin tie taiteilijuutta edeltävään minättömyyteen on kuitenkin vaikea ja monet merkit viittaavat diletantin kohtaloon. Unenomaisen logiikan omaavan, fragmentaarisen kerronnan takaa on hahmotettavissa myös lainalaisuuksia. Muiden henkilöiden lyhyet elämäkerrat ovat heidän haavansa paljastavia episodeja, jotka muuttuvat osaksi Danielin elämäntarinaa. Danielin kirjallinen omakuva on montaasi, jossa eri tasossa olevat elementit, nykyhetki ja menneisyys, mielikuvitus, unet ja upotetut monologit rinnastuvat samaan tasoon. Daniel peilaa elettyä ja koettua koomisen peilirakenteen avulla, jossa hänen elämäänsä osallisena olleet menneisyyden henkilöt kulkevat narrikulkueen mukana. Toive eheästä minäkuvasta osoittautuu kuitenkin mahdottomaksi merkityssulkeuman todenvastaisuuden vuoksi. Urwind-nimen pohdinnasta liikkeelle lähtenyt omaelämäkerta päättyy syklistä liikettä mukaillen tilanteeseen, jossa päähenkilö hyväksyy elämän käsittämättömyyden ja luottaa omassa nimessään piilevään voimaan, tuuleen, viitaten samalla myös romaanin nimeen. Avainsanat: Bo Carpelan - muistot - tila - fragmentaarisuus - fiktiivinen omaelämäkerta

Apparent digestibility of some nutrient sources by juvenile mud crab, Scylla serrata (Forskal 1775)

As part of preliminary work aimed at the development of a formulated diet for the mud crab, Scylla serrata, an experiment was conducted with juvenile mud crabs (95.65±2.17 g) to determine apparent digestibility coefficients (ADC) for cellulose, fish meal, shrimp meal, blood meal, soybean meal, wheat flour and cod liver oil. Apparent digestibility coefficients for dry matter (ADCdm), energy (ADCenergy) and protein (ADC protein) were in the ranges 70.0-95.7%, 77.4-97.1% and 57.7-97.9% respectively. Soybean meal had the highest ADCdm and wheat flour had the lowest value (P<0.05), while the ADCdm for fish meal, blood meal and shrimp meal were not different (P?0.05). Similarly, soybean meal had the same ADCenergy as that of fish meal, but higher than those of cod liver oil, blood meal and shrimp meal (P<0.05). Moreover, the ADC protein for blood meal or shrimp meal were not significantly different from fish meal (P?0.05); nevertheless, they were lower than that of soybean meal and higher than that of wheat flour (P<0.05). Of significant interest was the ADCdm (78.0%) and ADCenergy (77.4%) for cellulose, which indicates that plant-based nutrient sources may well be a useful component of formulated diets for mud crabs.

Stocking density and artificial habitat influence stock structure and yield from intensive nursery systems for mud crabs Scylla serrata (Forsskål 1775)

Intensive nursery systems are designed to culture mud crab postlarvae through a critical phase in preparation for stocking into growout systems. This study investigated the influence of stocking density and provision of artificial habitat on the yield of a cage culture system. For each of three batches of postlarvae, survival, growth and claw loss were assessed after each of three nursery phases ending at crab instars C1/C2, C4/C5 and C7/C8. Survival through the first phase was highly variable among batches with a maximum survival of 80% from megalops to a mean crab instar of 1.5. Stocking density between 625 and 2300 m-2 did not influence survival or growth in this first phase. Stocking densities tested in phases 2 and 3 were 62.5, 125 and 250 m -2. At the end of phases 2 and 3, there were five instar stages present, representing a more than 20-fold size disparity within the populations. Survival became increasingly density-sensitive following the first phase, with higher densities resulting in significantly lower survival (phase 2: 63% vs. 79%; phase 3: 57% vs. 64%). The addition of artificial habitat in the form of pleated netting significantly improved survival at all densities. The mean instar attained by the end of phase 2 was significantly larger at a lower stocking density and without artificial habitat. No significant effect of density or habitat on harvest size was detected in phase 3. The highest incidence of claw loss was 36% but was reduced by lowering stocking densities and addition of habitat. For intensive commercial production, yield can be significantly increased by addition of a simple net structure but rapidly decreases the longer crablets remain in the nursery.

Transdisciplinary collaboration in wound care research

The highly complex disorder of chronic wounds is a significant problem. Information is often lacking, dynamically changing, or contradictory and thus acts to impede the progression of research and its translation into clinical care. Transdisciplinary collaboration may play an important role in chronic wound research, permitting key stakeholders with a single, central goal to take a unified approach towards addressing the problem. While transdisciplinary collaboration is not a new concept, its implementation within chronic wound research is relatively new. This is because the research area is still largely dominated by single-discipline researchers or by multiple disciplines working in isolation. Transdisciplinary research is a transcending approach, requiring a greater level of understanding between disciplines and may represent the next leap forward in wound care research. This approach necessitates a deeper understanding by all team members of the co-disciplines involved; where key stakeholders are better equipped to respond to dynamic changes and problems that arise in chronic wound research. In this paper, we illustrate what a transdisciplinary approach in wound care research may entail, with the ultimate goal of such an undertaking to improve understanding of the complexities of wound care, which could lead to potential benefits in wound management.
