Combined assessment of stress cardiovascular magnetic resonance and angiography to predict the effect of revascularization in chronic coronary syndro…
2021
Abstract Aims The role of revascularization in chronic coronary syndrome (CCS) and the value of ischaemia vs. anatomy to guide decision-making are in constant debate. We explored the potential of a combined assessment of ischaemic burden by vasodilator stress cardiovascular magnetic resonance (CMR) and presence of multivessel disease by angiography to predict the effect of revascularization on all-cause mortality in CCS. Methods and results The study group comprised 1066 CCS patients submitted to vasodilator stress CMR pre-cardiac catheterization (mean age 66 ± 11 years, 69% male). Stress CMR-derived ischaemic burden (extensive if >5 ischaemic segments) and presence of multivessel di…
Long-term clinical outcomes after drug-eluting stent implantation in unprotected left main coronary artery disease.
2009
Objective: To investigate long-term outcomes of unprotected left main coronary artery (ULMCA) disease treatment using drug-eluting stents (DES). Background: In several studies, DES implantation in ULMCA appeared safe and effective at mid-term; however, to date, there is limited long-term data. Methods: All consecutive patients undergoing sirolimus- or paclitaxel-eluting stent implantation in ULMCA disease at a single institution were evaluated. The primary endpoint was long-term major adverse cardiac events (MACE) defined as cardiac death, nonfatal myocardial infarction, or target lesion revascularization (TLR). Stent thrombosis (ST), according to Academic Research Consortium definitions, w…
Identification of calcium sensing receptor (CaSR) mRNA-expressing cells in normal and injured rat brain
2009
Calcium sensing receptor (CaSR), isolated for the first time from bovine and human parathyroid, is a G-protein-coupled receptors that has been involved in diverse physiological functions. At present a complete in vivo work on the identification of CaSR mRNA-expressing cells in the adult brain lacks and this investigation was undertaken in order to acquire more information on cell type expressing CaSR mRNA in the rat brain and to analyse for the first time its expression in different experimental models of brain injury. The expression of CaSR mRNAs was found mainly in scattered cells throughout almost all the brain regions. A double labeling analysis showed a colocalization of CaSR mRNA expr…
Cross-sectional associations of objectively-measured sleep characteristics with obesity and type 2 diabetes in the PREDIMED-Plus trial.
2018
Study Objectives: To examine independent and combined associations of sleep duration and sleep variability with body composition, obesity and type 2 diabetes (T2D) in elders at high cardiovascular risk. Methods: Cross-sectional analysis of 1986 community-dwelling elders with overweight/obesity and metabolic syndrome from PREDIMEDPlus trial. Associations of accelerometry-derived sleep duration and sleep variability with body mass index (BMI), waist circumference (WC) and body composition were assessed fitting multivariable-adjusted linear regression models. Prevalence ratios (PR) and 95% confidence intervals (CI) for obesity and T2D were obtained using multivariable-adjusted Cox regression w…
Anesthesia protocols in laboratory animals used for scientific purposes
2018
Background: A suitable, effective and free of complications anesthetic protocol is very important in experimental studies on animal models since it could bias the outcome of a trial. To date there is no universally accepted protocol for induction, maintenance and recovery from anesthesia. The endotracheal intubation with the use of inhalation anesthesia is used very especially in the from of large size laboratory animals, because it is a secure and easy control mode. However, it is not common for small laboratory animals because of the high technical skills required. Aim: The aim of this paper is a review of the main methods of induction of anesthesia in laboratory animals. Materials and me…
Suitability of some existing damage indexes for assessing agreements in maintenance and management of museum climatization systems
2020
Heating, Ventilating and Air-Conditioning systems in museums are called to properly control important microclimate parameters, not only for visitors’ wellbeing, but mostly for the preservation of works of art. Accordingly, in case of interruptions to Heating, Ventilating and Air-Conditioning systems, due to maintenance interventions or drawbacks, it is essential to guarantee the acceptable break from service to which possible damages for the works of art are related. In this regard, the aim of this work is to introduce a simple indicator to support curators in regulating the stipulation of contracts with external companies, a more effective management and maintenance of the Heating, V…
FORMULATIONS OF THE MAIN GOAL IN LIFE: A QUALITATIVE CONTENT ANALYSIS
2018
Humanistic tradition emphasizes the main goal in life as something towards which people determine themselves. The main goal (or a group of goals with the highest priority) provides the basis for the sense of purpose in life and for development of its meaning. This study aimed at revealing categories in formulations of the main goal in life. Participants were 226 adults aged from 18 to 69 (M = 25.34, SD = 8.51, 65% females). They answered an open question: “Kā Jūs raksturotu galveno dzīves mērķi? Lūdzu, padalieties ar savām pārdomām. [How could You describe the main goal in life? Please, share your opinion.]” The qualitative content analysis resulted in 29 categories. Inter-rater agreement a…
Proposition du Project APER pour un entretien programé du Quartier hellénistique-romain d’Agrigente / Proposta del Progetto APER per la manutenzione …
2014
The article puts forward a proposal for the planned maintenance of the Sicilian study case chosen by the APER Project: House IA-B in Agrigento’s Hellenistic-Roman Quarter. After a few brief considerations regarding maintenance work on buildings and on architectural heritage, specific details concerning the maintenance of archaeological sites are illustrated. The article proposes a coding system specially applied to domestic Punic, Hellenistic and Roman architecture, designed to identify maintenance units, meaning parts of the archaeological built environment that can be the object of effectively planned maintenance work because they feature similar shapes and materials. This proposal should…
Collective Behavior of Price Changes of ERC-20 Tokens
2020
We analyze a network constructed from tokens developed on Ethereum platform. We collect a large data set of ERC-20 token prices; the total market capitalization of the token set is 50.2 billion (109) US dollars. The token set includes 541 tokens; each one of them has a market capitalization of 1 million US dollars or more. We construct and analyze the networks based on cross-correlation of tokens’ returns. We find that the degree distributions of the resulting graphs do not follow the power law degree distribution. We cannot find any hierarchical structures nor groupings of ERC-20 tokens in our analysis. peerReviewed
GRASP & evolutionary path relinking for medical image registration based on point matching
2010
Image registration is a very active research area in computer vision. Image registration methods, aim to find a transformation between two images taken under different conditions. Point matching is an image registration approach based on searching for the right pairing of points between the two images. From this matching, the registration transformation can be inferred by means of numerical methods. In this paper, we tackle the medical image registration problem adapting a new advanced hybrid metaheuristic composed by the GRASP and the evolutionary path relinking algorithms, called G&EvPR. The experiments conducted in this work have shown the good performance of G&EvPR compared to similar a…
