    L - Asparaginase is an amidohydrolase that catalyzes the hydrolysis of amino acid L - aspar a gine in to aspartic acid and ammonia. It is used in the treatment of Acute L ymphoblastic Leukemia (ALL ) and some other malignant lymphoid abnormalities . It is also used in food industry to prevent the formation of a crylamide , a carcinogenic substance in carbohydrate rich fried and baked foods. Naturally L - Asparaginase is present i n plants, animals and microbes but microorganisms such as bacteria, yeast and fungi are generally used for the production of L - Asparaginase as it is difficult to obtain the same from plants and animals. It is found that the L - Asparaginase from bacteria causes side effects in humans including anaphylaxis and serious allergic reactions which can be fatal in some cases . To overcome this, eukaryotic organisms such as fungi can be used for the production of L - Asparaginase . Bu t sometimes the fungi produces L - glutaminase and urease enzymes along with L - Asparaginase which is difficult to remove in the purification stage. In order to prevent this fungal strains which can produce L - Asparaginase fre e of L - glutaminase and urease are isolated from different sources using standard protocols

    Analysis of landrace cultivation in Europe: A means to support in situ conservation of crop diversity

    Get PDF
    During the last century, the progressive substitution of landraces with modern, high yielding varieties, led to a dramatic reduction of in situ conserved crop diversity in Europe. Nowadays there is limited and scattered information on where landraces are cultivated. To fill this gap and lay the groundwork for a regional landrace in situ conservation strategy, information on more than 19,335 geo-referenced landrace cultivation sites were collated from 14 European countries. According to collected data, landraces of 141 herbaceous and 48 tree species are cultivated across Europe: Italy (107 species), Greece (93), Portugal (45) and Spain (44) hold the highest numbers. Common bean, onion, tomato, potato and apple are the species of main interest in the covered countries. As from collected data, about 19.8% of landrace cultivation sites are in protected areas of the Natura 2000 network. We also got evidence that 16.7% and 19.3% of conservation varieties of agricultural species and vegetables are currently cultivated, respectively. Results of the GIS analysis allowed the identification of 1261 cells (25 km × 25 km) including all the cultivation sites, distributed across all European biogeographical regions. Data of this study constitute the largest ever produced database of in situ-maintained landraces and the first attempt to create an inventory for the entire Europe. The availability of such resource will serve for better planning of actions and development of policies to protect landraces and foster their use

    Values - reviewing the construct and drawing implications for values work in organisation and leadership. Kap. 2

    I: H.Askeland, G. Espedal, B. Jelstad Løvaas & S. Sirris (Eds.), Understanding values work : Institutional perspectives in organizations and leadershipThis chapter outlines the trajectory of values, particularly within streams of organisational institutionalism, in order to analyse its application to values work in organisation and leadership. Conveying a frame for discussing values work, it aims at clarifying how to conceptualise the term values. Discussing classic and recent contributions, the chapter proposes seeing values as individual and collective conceptions of desirable trans-situational behaviours, objectives and ideals, serving to guide or valuate practice. Despite being an essential part of defining organisational institutionalism, and its sub-streams, values are seldom explicated. Utilising values in organisational and leadership research requires attention to their situatedness in contexts, and this chapter argues they are salient to organisations operating in pluralistic institutional environment. Studying values work, attention should be given to who and how such work is performed.publishedVersio

    Disability, support and long-term social care of an elderly Spanish population, 2008-2009: an epidemiologic analysis

    BACKGROUND: Though poorly known, relationships between disability, need of help (dependency) and use of social services are crucial aspects of public health. The objective of this study was to describe the links between disability, officially assessed dependency, and social service use by an industrial population, and identify areas of inequity. METHODS: We took advantage of a door-to-door survey conducted in the Cinco Villas district, Spain, in 2008–2009, which provided data on disability, morbidity, and service use among 1216 residents aged ≥50 years, and officially assessed dependency under the 2006 Dependency Act (OAD). Using logistic regression, we combined data collected at homes/residences on 625 disability screened-positive participants, and administrative information on degree of OAD and benefits at date of visit. RESULTS: Based on 163 disabled persons, the prevalence of residential/community-care users was 13.4% overall, with 6.0% being market-provided, 2.5% supported by the 2006 Act, and 4.9% supported by other public funds. Of 111 OAD applicants, 30 had been assigned an OAD degree; in 29 cases this was the highest OAD degree, with 12 receiving direct support for residential care and 17 receiving home care. Compared to unassessed dependency, the highest OAD degree was linked to residential care (OR and 95% CI) 12.13 (3.86–38.16), declared non-professional care 10.99 (1.28–94.53), and publicly-funded, non-professional care 26.30 (3.36–205.88). In contrast, 43 persons, 58% of the severely/extremely disabled, community-dwelling sample population, 81% of whom were homebound, including 10 persons with OAD but no implemented service plan, made no use of any service, and of these, 40% lacked a non-professional carer. CONCLUSIONS: Formal service use in the Cinco Villas district attained ratios observed for established welfare systems but the publicly-funded proportion was lower. The 2006 Act had a modest, albeit significant, impact on support for non-professional carers and residential care, coexisting with a high prevalence of non-use of social services by severely disabled persons

    Epigenetic clock for skin and blood cells applied to Hutchinson Gilford Progeria Syndrome and ex vivo studies

    DNA methylation (DNAm)-based biomarkers of aging have been developed for many tissues and organs. However, these biomarkers have sub-optimal accuracy in fibroblasts and other cell types used in ex vivo studies. To address this challenge, we developed a novel and highly robust DNAm age estimator (based on 391 CpGs) for human fibroblasts, keratinocytes, buccal cells, endothelial cells, lymphoblastoid cells, skin, blood, and saliva samples. High age correlations can also be observed in sorted neurons, glia, brain, liver, and even bone samples. Gestational age correlates with DNAm age in cord blood. When used on fibroblasts from Hutchinson Gilford Progeria Syndrome patients, this age estimator (referred to as the skin & blood clock) uncovered an epigenetic age acceleration with a magnitude that is below the sensitivity levels of other DNAm-based biomarkers. Furthermore, this highly sensitive age estimator accurately tracked the dynamic aging of cells cultured ex vivo and revealed that their proliferation is accompanied by a steady increase in epigenetic age. The skin & blood clock predicts lifespan and it relates to many age-related conditions. Overall, this biomarker is expected to become useful for forensic applications (e.g. blood or buccal swabs) and for a quantitative ex vivo human cell aging assay

    “Older-wiser-lesbians” and “baby-dykes”: mediating age and generation in New Queer Cinema

    Get PDF
    Representations of intersections of gender, age, and sexuality can reveal deep-rooted cultural anxieties about older women and sexuality. Images of lesbian ageing are of particular interest in terms of alterity, as the old/er queer woman can combine layers of otherness—not only is she the cultural “other” within heteronormativity, but she can also appear as the opposite of popular culture’s lesbian chic. In this article, a cultural analysis of a range of films—If These Walls Could Talk 2 (dir. Anderson, Coolidge, and Heche 2000), Itty Bitty Titty Committee (dir. Babbit 2007), The Owls (dir. Dunye 2010), Hannah Free (dir. Carlton 2009), and Cloudburst (dir. Fitzgerald 2011)—considers diverse dramatisations of lesbian generations. This article interrogates to what extent alternative cinemas deconstruct normative conceptualisations of ageing. Drawing on recent critiques of post-feminist culture, and a range of feminist and age/ing studies scholarship, it suggests that a linear understanding of ageing and the generational underlies dominant depictions of oppositional binaries of young versus old, of generational segregation or rivalry, and the othering of age. It concludes that non-linear understandings of temporality and ageing contain the potential for New Queer Cinema to counteract such idealisations of youthfulness, which, it argues, is one of the most deep-rooted manifestations of (hetero)normativity
