The neuropeptide 26RFa (QRFP) is a key regulator of glucose homeostasis and its activity is markedly altered in obese/hyperglycemic mice

2019

International audience; Recent studies have shown that the hypothalamic neuropeptide 26RFa regulates glucose homeostasis by acting as an incretin, and increasing insulin sensitivity. In this study, we further characterized the role of the 26RFa/GPR103 peptidergic system in the global regulation of glucose homeostasis using a 26RFa receptor antagonist, and also assessed whether a dysfunction of the 26RFa/GPR103 system occurs in obese hyperglycemic mice. Firstly, we demonstrate that administration of the GPR103 antagonist reduces the global glucose-induced incretin effect and insulin sensitivity whereas, conversely, administration of exogenous 26RFa attenuates glucose-induced hyperglycemia.

A short proof of a theorem of Juhasz

2011

Abstract We give a simple proof of the increasing strengthening of Arhangelʼskii Theorem. Our proof naturally leads to a refinement of this result of Juhasz.

Construction of chaotic dynamical system

2010

The first‐order difference equation xn+ 1 = f(xn ), n = 0,1,…, where f: R → R, is referred as an one‐dimensional discrete dynamical system. If function f is a chaotic mapping, then we talk about chaotic dynamical system. Models with chaotic mappings are not predictable in long‐term. In this paper we consider family of chaotic mappings in symbol space S 2. We use the idea of topological semi‐conjugacy and so we can construct a family of mappings in the unit segment such that it is chaotic. First published online: 09 Jun 2011

Coincidence and fixed points for contractions and cyclical contractions in partial metric spaces

2012

Abstract We prove some coincidence and common fixed point results for three mappings satisfying a generalized weak contractive condition in ordered partial metric spaces. As application of the presented results, we give a unique fixed point result for a mapping satisfying a weak cyclical contractive condition. We also provide some illustrative examples.

Financial Behaviour Under Economic Strain in Different Age Groups: Predictors and Change Across 20 Years

2021

AbstractThe present study examined the multiple micro- and macro-level factors that affect individuals’ financial behaviour under economic strain. The following sociodemographic and economic factors that predict financial behaviour were analysed: age group, year of data gathering, and attitudes towards consumption (economical, deprived, and hedonistic). Subjective financial situations and demographic characteristics were controlled for. Finnish time series data that consisted of five cross-sectional nationally representative surveys were used (n = 10 043). The analyses revealed four types of financial behaviour: cutting expenses, borrowing, increasing income, and gambling. Young adults aged…

One hundred and fifty years of ornithology in Sicily, with an unknown manuscript by Joseph Whitaker

2021

A new complete check-list of Birds of Sicily is presented in this paper, with a comparison with previous lists for a period of one hundred and fifty years. Further, an unknown manuscript by Joseph Whitaker “Birds of Sicily”, dated back to ca. 1920, has been transcribed and is here presented integrally. Thus, lists of birds here presented have been separated as follows: i) Doderlein (1869–1874); ii) Whitaker (1920); iii) Iapichino & Massa (1989), Lo Valvo et al. (1993) iv) Corso (2005), Ientile & Massa (2008); v) 2010–2020: Massa et al. (2015) and personal observations; vi) long-term trend: personal observations. Overall, 437 species are listed. Out of 283 species regularly present i…

Protein isotope effects in dihydrofolate reductase from Geobacillus stearothermophilus show entropic-enthalpic compensatory effects on the rate const…

2014

Catalysis by dihydrofolate reductase from the moderately thermophilic bacterium Geobacillus stearothermophilus (BsDHFR) was investigated by isotope substitution of the enzyme. The enzyme kinetic isotope effect for hydride transfer was close to unity at physiological temperatures but increased with decreasing temperatures to a value of 1.65 at 5 °C. This behavior is opposite to that observed for DHFR from Escherichia coli (EcDHFR), where the enzyme kinetic isotope effect increased slightly with increasing temperature. These experimental results were reproduced in the framework of variational transition-state theory that includes a dynamical recrossing coefficient that varies with the mass of…

Drāma angļu valodas stundās lasīšanas motivācijas paaugstināšanai

2016

Pētijuma darbs “Drāmas izmantošana angļu valodas stundās skolēnu lasīšanas motivācijas paaugstināšanai” bija saistīts ar skolēnu veicināšanu lasīt visaptveroši. Ir svarīgi motivēt skolēnus lasīt daiļliteratūru tāpēc, ka lasīšana dod skolēniem iespēju attīstīt viņu valodas prasmes. Tā kā šī darba autores aptauja parādīja ka daļa no Rīgas 60. vidusskolas skolēniem nelasa visaptveroši, šī pētījuma darba mērķis bija parādīt kā drāmas izmantošana stundās un ārpusstundu aktivitātēs var veicināt gan skolēnus visaptverošai lasīšanai gan paaugstināt skolēnu lasīšanas motivāciju. Lai sasniegtu mērķi un izpildītu darba uzdevumus, tika pielietota gadījuma izpētes metode. Hipotēze – dažādas drāmas veidi…

Viaggi nell’immaginario: il turismo virtuale nel sito UNESCO di Tarragona

2023

Le nuove tecnologie hanno trasformato in modo radicale non solo la geografia come disciplina, ma anche le geografie del mondo. Il digitale ha assunto, infatti, un ruolo di mediazione sempre più pervasivo nella produzione dello spazio, come delle conoscenze e degli immaginari geografici. Le possibilità offerte dal virtuale, in particolare, offrono oggi un contributo decisivo nella comunicazione dei significati attribuiti ai luoghi e rispondono in modo sempre più efficace ai bisogni emergenti del settore turistico. Le esperienze di visita mediate dal digitale mirano a coinvolgere i sensi e risultano efficaci quando promuovono immersioni rigorosamente realistiche. Nel quadro di queste riflessi…
