Mārupītes sedimentu fitotoksiskums un smago metālu saturs tajos
2017
Maģistra darba nosaukums ir “Mārupītes sedimentu fitotoksiskums un smago metālu saturs tajos”. Maģistra darba mērķis ir novērtēt Mārupītes kā urbānas ūdensteces sedimentu fitotok-sicitāti un veikt sedimentu ķīmiskās kvalitātes novērtējumu pēc smago metālu koncentrācijām tajos, lai novērtētu pilsētas upes sindroma izpausmes Mārupītes ūdensteces ekosistēmā. Pirmajā daļā apskatīta ūdenstece kā ekosistēma, pilsētas upes sindroma izpausmes tajā un sedimentu raksturojums un nozīme ūdensteču ekosistēmās. Apskatīti pētījumi par smago me-tālu piesārņojumu pilsētu ūdensteču sedimentos pasaulē un pētījumi par smago metālu piesār-ņojumu un izplatību Latvijas iekšzemes ūdeņu (upju un ezeru) sedimentos. …
Tietoturvan ja tietosuojan kehittäminen pilviteknologiassa : standardit ja kehysmallit sekä riskienhallinnan näkökulma
2010
Informaatioteknologian kehityksen myötä on syntynyt idea tietojenkäsittelyn myymisestä palveluna minkä tahansa hyödykkeen tavoin. Kustannustehokas, skaalautuva ja helppokäyttöinen pilviteknologia herättää mielenkiintoa eri puolilla maailmaa. Internetin yli tarjottavien pilvipalveluiden tietoturva ja tietosuoja vaativat kuitenkin erityishuomiota yritysten ulkoistaessa tietojenkäsittelynsä kolmannen osapuolen hoidettavaksi. Tietoturvan tai tietosuojan pettäminen on merkittävä riski eri osapuolille. Tästä syystä yritysten liikesalaisuudet tai yksilöiden arkaluontoiset tiedot tulee riskien realisoitumisen välttämiseksi suojata asianmukaisin keinoin. Erilaisten tietojenkäsittelystandardien ja - …
Dzemdību indukcija pirmdzemdētājām, tās iznākumi un ķeizargrieziena riska faktoru analīze
2020
Ievads. Pasaulē par globālu problēmu ir kļuvis pieaugošais ķeizargreizienu skaits. Tas ir radījis diskusijas par tā ietekmi uz mātes un perinatālajiem iznākumiem, kā arī nav zināmi skaita palielināšanās iemesli. Kopā ar ķeizargriezienu skaitu pieaug arī inducētu dzemdību skaits. Darba mērķis. Salīdzināt mātes un jaundzimušā iznākumus vaginālu dzemdību un ķeizargrieziena grupās, kā arī izpētīt ķeizargrieziena riska faktorus zema riska inducētās dzemdībās pirmdzemdētāju vidū. Materiāli un metodes. Tika veikts retrospektīvs pētījums Rīgas Dzemdību namā. Pētījumā tika iekļautas zema riska pirmdzemdētājas ar vienaugļa grūtniecību, kurām veikta dzemdību indukcija. Pirmdzemdētājas tika sadalītas v…

Comparison of 99mTc-Labeled Colloid SPECT/CT and Planar Lymphoscintigraphy in Sentinel Lymph Node Detection in Patients with Melanoma: A Meta-Analysis
2020
We compared the detection rate (DR) for sentinel lymph nodes (SLNS), the number of SLNs and the subjects with additional SLNs of single-photon emission computed tomography (SPECT/CT) and planar lymphoscintigraphy (PL) in patients with melanoma. Furthermore, we evaluated the impact of SPECT/CT on surgical plans. Articles containing head-to-head comparisons between SPECT/CT and PL were searched in Pubmed/MEDLINE and Scopus. The literature search was updated until December 31st, 2019. DR was calculated on a per-patient-based analysis; the studies were pooled by their odds ratios (ORs) with a random effects model to assess the significance of difference (p < 0.05). The number of additional S…
Extinction risk indices for measuring and promoting planetary well-being
2024
The concept of planetary well-being, which stresses the persistence of lineages in ecosystems, is intimately linked to species extinction risk. Avoiding extinctions is a moral issue, as wiping out the outcomes of eons of evolutionary history and their future potential is clearly unconscionable. The concept of planetary well-being is also systemic: It is understood that species, as integral parts of ecosystems, are vital for the well-being of all systems on Earth. Yet, despite international agreements to protect biodiversity, global biodiversity loss and ecosystem degradation has continued unimpeded over the past decades. We review the role of goals and targets in the UN Convention on Biolog…
Applying an operating model for the environmental risk assessment in Italian Sites of Community Importance (SCI) of the European Commission Habitats …
2013
The fast development of agro-biotechnologies asks for a harmonized approach in risk analysis of GMO's releases, where "risk analysis" entails the assessment, management and communication of risk. Risk assessment consists in the evaluation of the likelihood that a hazard occurs, associated with the presence of the receptor(s) in the receiving environment, and the determination of their potential degree of exposure to the hazard. The whole process has to be both science based and applied case by case, and it involves a very complicated procedure that needs to be transformed in an operational and standardized tool. Beginning in 2003, an expert group on behalf of the Italian Ministry of the Env…
Plasma PAF-acetylhydrolase in patients with coronary artery disease: results of a cross-sectional analysis.
2003
Inflammation underlies both onset and perpetuation of atherosclerosis. Plasma lipoproteins transport the platelet-activating factor-acetylhydrolase (PAF-AH) with potentially anti-inflammatory activities. Our aim was to determine whether PAF-AH activity was associated with inflammatory markers and with coronary artery disease (CAD). PAF-AH activity and a panel of inflammatory mediators were measured in plasma of 496 patients with CAD and in 477 controls; 276 patients presented with stable angina pectoris and 220 with acute coronary syndrome (ACS). Individuals within the highest quartile of PAF-AH activity had an 1.8-fold increase in CAD risk [95% confidence interval (CI), 1.01 to 3.2; P = 0.…
Data from: Deceiving predators: linking distraction behavior with nest survival in a ground-nesting bird
2016
Individual behavior that minimizes predation risk is favored by natural selection. Ground-nesting birds employ different defensive behaviors as part of their antipredator strategies because they nest where a wide range of predators have access. We investigated the influence of distraction displays on breeding success in the Kentish Plover, Charadrius alexandrinus, in order to explore the role of the defensive behavior on nest survival. We quantified the intensity of defensive behavior of adult plovers in response to nest disturbance caused by an approaching researcher, by ranking display types according to the intensity and exposure to predation. We also examined sex differences in nest def…
Risk narrations and perceptions in the COVID-19 time. A discourse analysis through the Italian press
2020
This paper explores how the risk related to the pandemic of COVID-19 was managed, narrated and perceived in Italy during the lockdown phase, from February until June 2020. To reach this aim, the study provides a discourse analysis of three main level: the official institutional discourses declaimed by the government and the health authority; the risk narration spread through the diaphragm of the Italian press, and specifically through two of the most-read newspapers in Italy (Repubblica and Corriere della Sera) and their related weeklies (Venerdì di Repubblica and Sette); finally, the diverse reactions and perceptions to the risk coming from the most affected and most vulnerable subjects, c…
