Circulating microRNAs: The Future of Biomarkers in Anti-doping Field.

microRNAs (miRNAs) are small non-coding RNAs that regulate various biological processes. Cell-free miRNAs have been proposed as biomarkers of disease, including diagnosis, prognosis, and monitoring of treatment responses. These circulating miRNAs are highly stable in several body fluids, including plasma and serum; hence, in view of their potential use as novel, non-invasive biomarkers, the profiles of circulating miRNAs have been explored in the field of anti-doping. This chapter describes the enormous potential of circulating miRNAs as a new class of biomarkers for the detection of doping substances, and highlights the advantages of measuring these stable species over other methods that have already been implemented in anti-doping regimes. Incorporating longitudinal measurements of circulating miRNAs into the Athlete Biological Passport is proposed as an efficient strategy for the implementation of these new biomarkers. Furthermore, potential challenges related to the transition of measurements of circulating miRNAs from research settings to practical anti-doping applications are presented.

La inclusión laboral y social de los jóvenes con discapacidad intelectual : el papel de la escuela = Work and social inclusion of young people with intellectual disabilities : the role of the school

The transition to adult life from the standpoint of inclusion is a complex process, especially for young people with intellectual disabilities. This article analyzes the context of transition processes showing the main relationships and differences of the different scenarios where young people with disabilities develop personal pathways that lead to adulthood. Among these scenarios, the school -the period of compulsory secondary education- plays a key role. Therefore, a specific section is devoted to developing an approach to the role of the school in the construction of bridges that facilitate social and work inclusion. Finally, it presents some major challenges that need to be faced to improve the processes of transition from an inclusive perspective

Lesões em DNA induzidas pela autoxidação de S(IV) na presença de íons metálicos de transição

The oxidation of sulfite catalyzed by transition metal ions produces reactive oxysulfur species that can damage plasmid and isolated DNA in vitro. Among the four DNA bases, guanine is the most sensitive to one-electron oxidation promoted by the species formed in the autoxidation of sulfite (HSO5-, HO•, SO3•-, SO4•- and SO5•-) due to its low reduction potential and ability to bind transition metal ions capable to catalyze oxidative processes. Some oxidative DNA lesions are promutagenic and oxidative DNA damage is proposed to play a crucial role in certain human pathologies, including cancer.

Teollisuusvaihteen kokoonpanoprosessin laadun parantaminen

Paperikoneen telalle integroitujen mekaanisten käyttölaitteiden valmistuksen siirtoprojektin yhteydessä on raportoitu huomattavan paljon valmistuksen aikaisia poikkeamia. Poikkeamien juurisyyn hahmottamiseksi tehtiin kvantitatiivinen analyysi raportoiduista poikkeamista ja kvalitatiivinen analyysi kokoonpanon nykytilasta. Kokoonpanotyöstä suuri osa on tällä hetkellä arvoa jalostamatonta työtä. Tutkimuksessa havaittiin valmistusprosessissa kaikkia kokoonpanon poikkeamien perustyyppejä ja näitä poikkeamia olivat aiheuttaneet kaikki mahdolliset aiheuttajat. Etenkin hankittavien osien laatua tulisi käsitellä poikkeamien aiheuttamien kokonaiskustannusten kautta. Kokoonpanon tarvitsema tieto on olemassa täsmällisessä muodossa, mutta sen luoksepäästävyys on huono. Prosessin kuvauksella, hiljaisen tiedon kirjaamisella ja täsmällisen tiedon julkistamisella voidaan parantaa tuotannon laatua tuotetuntemuksen parantuessa. Käyttökohteen tunteminen parantaa vaatimusten ymmärtämistä. Tutkimuksessa havaittujen poikkeamien analysoinnin perusteella erityistä huomiota tulisi kiinnittää tarkastusvaiheiden olemassa oloon, sijoitukseen ja niiden laatuun. Suuri osa poikkeamista oli edennyt kokoonpanoon jonkin tarkastusvaiheen läpi. Tarkastusvaiheiden laatutason tulee parantua, jotta moninkertaisesta tarkastuksesta voidaan luopua.

INFLUÊNCIA DO TRATAMENTO TÉRMICO NO NANOCOMPÓSITO FOTOCATALISADOR ZnO/TiO2

ZnO/TiO2 nanocomposites were prepared by impregnating zinc acetate dihydrate on the surface of titanium dioxide P25, followed by thermal treatment at 350, 600, 750, and 900 °C, in order to investigate the TiO2 phase and titanate formation and the role of the latter in the photocatalytic activity of the nanocomposite. In the nanocomposites, the anatase-to-rutile transition is favored due to the presence of Zn2+, and the conversion is nearly complete at 750 °C. The presence of zinc metatitanate in the sample heated at 600 °C had no significant effect on the nanocomposite photocatalytic activity.

Military crisis management in the next decade (2020-2030) : inducing consent or relying on compliance?

The most outstanding conceptual challenge of modern crisis management is the principle of consent. It is not a problem only at the operational level - it challenges the entire decision-making structures of crisis management operations. In post-cold war times and especially in the 21st century, there has been a transition from peacekeeping with limited size and scope towards large and complex peace operations. This shift has presented peace operations with a dilemma. How to balance between maintaining consent for peace operations, whilst being able to use military force to coerce those attempting to wreck peace processes? To address such a dilemma, this research aims to promote understanding, on what can be achieved by military crisis management operations (peace support operations) in the next decade. The research concentrates on the focal research question: Should military components induce consent or rely on the compliance of conflicting parties in crisis management operations of the next decade (2020 – 2030)? The focus is on military – political strategic level considerations, and especially on the time before political decisions to commit to a crisis management operation. This study does not focus on which actor or organisation should intervene. The framework of this thesis derives from the so called ‘peacebuilding space’, the scope of peace operations and spoiler theory. Feasibility of both peace enforcement and peacekeeping in countering future risk conditions are analysed in this framework. This future-orientated qualitative research uses the Delphi-method with a panel of national and international experts. Citation analysis supports identification of relevant reference material, which consists of contemporary literature, the Delphi-questionnaires and interviews. The research process followed three main stages. In the first stage, plausible future scenarios and risk conditions were identified with the Delphi-panel. In the second stage, operating environments for peace support operations were described and consequent hypotheses formulated. In the third stage, these hypotheses were tested on the Delphi-panel. The Delphi-panel is sufficiently wide and diverse to produce plausible yet different insights. The research design utilised specifically military crisis management and peace operations theories. This produced various and relevant normative considerations. Therefore, one may argue that this research; which is based on accepted contemporary theory, hypotheses derived thereof and utilising an expert panel, contributes to the realm of peace support operations. This research finds that some degree of peace enforcement will be feasible and necessary in at least the following risk conditions: failed governance; potential spillover of ethnic, religious, ideological conflict; vulnerability of strategic chokepoints and infrastructures in ungoverned spaces; as well as in territorial and extra-territorial border disputes. In addition, some form of peace enforcement is probably necessary in risk conditions pertaining to: extremism of marginalised groups; potential disputes over previously uninhabited and resource-rich territories; and interstate rivalry. Furthermore, this research finds that peacekeeping measures will be feasible and necessary in at least risk conditions pertaining to: potential spillover of ethnic, religious, ideological conflict; uncontrolled migration; consequences from environmental catastrophes or changes; territorial and extra-territorial border disputes; and potential disputes over previously uninhabited and resource-rich territories. These findings are all subject to both generic and case specific preconditions that must exist for a peace support operation. Some deductions could be derived from the research findings. Although some risk conditions may appear illogical, understanding the underlying logic of a conflict is fundamental to understanding transition in crisis management. Practitioners of crisis management should possess cognizance of such transition. They must understand how transition should occur from threat to safety, from conflict to stability – and so forth. Understanding transition is imperative for managing the dynamic evolution of preconditions, which begins at the outset of a peace support operation. Furthermore, it is pertinent that spoilers are defined from a peace process point of view. If spoilers are defined otherwise, it changes the nature of an operation towards war, where the logic is breaking the will of an enemy - and surrender. In peace support operations, the logic is different: actions towards spoilers are intended to cause transition towards consent - not defeat. Notwithstanding future developments, history continues to provide strategic education. However, the distinction is that the risk conditions occur in novel futures. Hence, lessons learned from the past should be fitted to the case at hand. This research shows compelling evidence that swaying between intervention optimism and pessimism is not substantiated. Both peace enforcement and peacekeeping are sine qua non for successful military crisis management in the next decade.

Tuning cell motility : roles of nestin and vimentin in cancer cell invasion and motility

The cytoskeleton is a key feature of both prokaryotic and eukaryotic cells. Itis comprised of three protein families, one of which is the intermediate filaments (IFs). Of these, the IFs are the largest and most diverse. The IFs are expressed throughout life, and are involved in the regulation of cell differentiation, homeostasis, ageing and pathogenesis. The IFs not only provide structural integrity to the cell, they are also involved in a range of cellular functions from organelle trafficking and cell migration to signalling transduction. The IFs are highly dynamic proteins, able to respond and adapt their network rapidly in response to intra- and extra- cellular cues. Consequently they interact with a whole host of cellular signalling proteins, regulating function, and activity, and cellular localisation. While the function of some of the better-known IFs such as the keratins is well studied, the understanding of the function of two IFs, nestin and vimentin, is poor. Nestin is well known as a marker of differentiation and is expressed in some cancers. In cancer, nestin is primarily described as is a promoter of cell motility, however, how it fulfils this role remains undefined. Vimentin too is expressed in cancer, and is known to promote cell motility and is used as a marker for epithelial to mesenchymal transition (EMT). It is only in the last decade that studies have addressed the role that vimentin plays in cell motility and EMT. This work provides novel insight into how the IFs, nestin and vimentin regulate cell motility and invasion. In particular we show that nestin regulates the cellular localisation and organisation of two key facilitators of cell migration, focal adhesion kinase and integrins. We identify nestin as a regulator of extracellular matrix degradation and integrin-mediated cell invasion. Two further studies address the specific regulation of vimentin by phosphorylation. A detailed characterisation study identified key phosphorylation sites on vimentin, which are critical for proper organisation of the vimentin network. Furthermore, we show that the bioactive sphingolipids are vimentin network regulators. Specifically, the sphingolipids induced RhoA kinasedependent (ROCK) phosphorylation at vimentin S71, which lead to filament reorganisation and inhibition of cell migration. Together these studies shed new light into the regulation of nestin and vimentin during cell motility.

Brazil on the spot: Rio+20, sustainability and a role for science

Rio +20, or the United Nations Conference for Sustainable Development, will take place at the end of this month of June 2012. In this paper, our central argument is that Brazil, as the host of Rio+20, has a historic opportunity to make the conference a success and take a decisive step in becoming a world leader in the shift from the traditional development paradigm to a new, sustainable development paradigm. To do that, Brazil will have to resolve a paradox: on the one hand the country has modern legislation and world class science, and on the other hand very poor social and environmental decision-making in recent times. In this column, we examine the green economy as a trajectory that leads to sustainable development and describe some pilot experiences at the sub-national level in Brazil. We discuss how science, and particularly plant sciences, will be essential to the transition to sustainable development. Finally, we propose immediate actions that we call upon the Brazilian government to commit to and to announce during this pivotal Rio+20 moment, which should serve as a milestone for all nations in building a sustainable future.

PK-yrityksen omistajanvaihdos tietojohtamisen näkökulmasta – tiedon jakaminen ja absorptiivinen kapasiteetti

PK-yritysten omistajanvaihdokset koskettavat vuoteen 2020 mennessä Suomessa noin 250000 ihmistä. Yhteiskunnan kannalta on tärkeää, että vaihdokset onnistuvat ja yritykset säilyttävät kilpailukykynsä, pystyvät kehittymään, kasvamaan kannattavasti ja työllistämään lisää henkilökuntaa. Työn tavoitteena on ymmärtää ja selittää PK-yrityksen omistajanvaihdosta tietojohtamisen näkökulmasta. Tutkimus toteutettiin vertailevana tapaustutkimuksena. Aineisto kerättiin puolistrukturoiduilla teemahaastatteluilla. Luopujan hiljaisen tiedon ja jatkajan yritykseen tuoman uuden tiedon onnistunut hyödyntäminen on oleellista PK-yritysten omistajanvaihdosten onnistumisessa. Luopujan hiljaisen tiedon siirtäminen jatkajalle ylläpitää yrityksen kilpailukykyä. Jatkajan yritykseen tuoma uusi tieto puolestaan voi laukaista tiedon hankinnan, sulattamisen, muokkaamisen ja hyödyntämisen prosessin, jonka kautta yrityksen kilpailukykyä voidaan parantaa tehostamalla prosesseja tai parantamalla tuotteita ja palveluita. Yksilöiden välinen tiedon jakaminen, siirtäminen ja rakentaminen ovat prosesseja, jotka kasvattavat yrityksen absorptiivistä kapasiteettiä tehostamalla tiedon sulattamista ja muuntamista. Tätä kautta voidaan osaltaan selittää omistajanvaihdokseen liittyviä riskejä ja mahdollisuuksia.
