Structure-determined thermoelectric properties of Bi2Se3 thin films deposited by vapour-solid technique
2018
International audience; In this work, a simple catalyst-free vapour-solid deposition method is applied for controlled obtaining of two types (planar and disordered) continuous Bi2Se3 nanostructured thin films on different (fused quartz/glass, mica, graphene) substrates. Performed for the deposited thin films transport and thermoelectric characterization (type, concentration and mobility of the main charge carriers, Seebeck coefficient and power factor) showed that proposed deposition method allows to fabricate “low-doped” Bi2Se3 thin films with power factor comparable and even higher than reported for the Bi2Se3 thin films fabricated by molecular beam epitaxy technique.
Comparative architectural aspects of regions of conserved synteny on human chromosome 11p15.3 and mouse chromosome 7 (including genes WEE1 and LMO1)
2001
Human chromosome 11p15.3 is associated with chromosome aberrations in the Beckwith Wiedemann Syndrome and implicated in the pathogenesis of different tumor types including lung cancer and leukemias. To date, only single tumor-relevant genes with linkage to this region (e.g. LMO1) have been found suggesting that this region may harbor additional potential disease associated genes. Although this genomic area has been studied for years, the exact order of genes/chromosome markers between D11S572 and the WEE1 gene locus remained unclear. Using the FISH technique and PAC clones of the flanking markers we determined the order of the genomic markers. Based on these clones we established a PAC cont…
Factors influencing psychological well-being in patients with Parkinson's disease.
2017
Background Both motor and non-motor symptoms could contribute to significant deterioration of psychological well-being in patients with Parkinson's disease (PD). However, its assessment has been only indirectly evaluated using tools based on health-related quality of life (HRQoL), such as the PDQ-39 scale. Objectives To evaluate psychological well-being in PD using a specific tool of assessment, the Psychological Well-being Scale (PWS), and its clinical correlates. Methods This article reports data of patients' perception of health state, as measured by means of the PWS, from an epidemiological, cross-sectional study conducted in Italian PD patients (FORTE Study). We tested possible relatio…
Advanced glycation end products measured by skin autofluorescence are associated with melancholic depressive symptoms - Findings from Helsinki Birth …
2021
Background: Millions of people live with depression and its burden of disease. Depression has an increased comorbidity and mortality that has remained unexplained. Studies have reported connections between advanced glycation end products (AGEs) and various disease processes, including mental health. The present study evaluated associations between AGEs, depressive symptoms, and types of depressive symptoms. Methods: From the Helsinki Birth Cohort Study, 815 participants with a mean age of 76 years were recruited for this cross-sectional study. Characteristics regarding self-reported lifestyle and medical history, as well as blood tests were obtained along with responses regarding depressive…
Beckwith-Wiedemann-Syndrom
2010
Zusammenfassung Das Beckwith-Wiedemann-Syndrom (BWS) ist ein pädiatrisches Überwuchssyndrom mit variablem klinischem Erscheinungsbild. Obwohl die betroffenen Kinder mit zunehmendem Alter immer normaler aussehen, ist es wichtig, die Diagnose BWS zu stellen. Gründe sind mögliche syndromspezifische Komplikationen, insbesondere ein 400-fach erhöhtes Risiko der Patienten, an bestimmten embryonalen Tumoren – Nephroblastome (Wilms-Tumoren), Hepatoblastome u. a. – innerhalb der ersten Lebensjahre zu erkranken. Klinisch überlappt das BWS mit anderen Krankheitsentitäten, sodass eine eindeutige molekulargenetische Diagnostik zur Risikoabschätzung und adäquaten Therapie wünschenswert ist. Molekular ist…
Biological Properties of a Citral-Enriched Fraction of Citrus limon Essential Oil
2020
Lemon essential oil (LEO) is a well-known flavoring agent with versatile biological activities. In the present study, we have isolated and characterized four citral-enriched fractions of winter LEO. We reported that in murine and human macrophages the pre-treatment with a mix of these fractions (Cfr-LEO) reduces the expression of the pro-inflammatory cytokines TNF-&alpha
Impact of Depression on Patients With Hemophilia: A Retrospective Case-Control Research
2022
BackgroundHemophilia is an inherited recessive hemorrhagic disorder of the X-linked type, suffered by the male sex. Adults with hemophilia are coping with numerous diagnostics, associated comorbidities, pain, and difficult gait by arthropathy in ankles and feet. Physical pains contribute to depression in patients with hemophilia.PurposeThe study aimed to assess the impact of depression in adult patient with hemophilia and to compare it with healthy matched-paired controls. Methods: The sample consisted of 100 participants (median age 42.50 ± 30). Patients with hemophilia were recruited from Spanish Hemophiliac Associations (n = 50) and healthy subjects (n = 50) from a Clinic Podiatry Practi…
Thermoelectric Heat Exchange and Growth Regulation in a Continuous Yeast Culture
2018
We have designed a thermoelectric heat exchanger (TEHE) for microbial fermentations that is able to produce electric power from a microbial continuous culture using the intrinsic heat generated by microbial growth. While the TEHE was connected, the system proved able to stably self-maintain both the temperature and the optical density of the culture. This paves the way toward a more sustainable operation of microbial fermentations, in which energy could be saved by converting part of the metabolic heat into usable electric power.

Review of the volume that is configured as an essay on the declamatory phenomenon as a whole, but above all as a reading entirely internal to the first corpus of declamatory texts by Seneca il Vecchio that has come down to us
Lewis acid-catalyzed Beckmann rearrangement of ketoximes in ionic liquids
2009
Abstract The Beckmann rearrangement of five ketoximes was done in 17 different ionic liquids by using four Lewis acids. The effect of the type of cation and the type of anion in the ionic liquid on the rate of the rearrangement reaction and product composition is compared and discussed. The effects of the hydrophobicity and the hydrogen bonding ability of ionic liquids on the rearrangement of ketoximes were investigated, as well as the catalytical activity of the Lewis acids.
