Ant crickets and their secrets: Myrmecophilus acervorum is not always parthenogenetic (Insecta: Orthoptera: Myrmecophilidae)

2021

Abstract Previously considered as a thelytokous parthenogenetic species, the widespread ant cricket Myrmecophilus acervorum actually turns out to have a mixed reproductive system: our recent surveys in the central part of its distribution area has revealed the presence of both sexes. Detailed morphological and morphometric descriptions of the previously unknown males are here provided. New data on species distribution in south-eastern Europe are presented, including the first records of M. balcanicus in Bulgaria and of M. nonveilleri in Bulgaria and Hungary. Phylogenetic and phylogeographic analyses have revealed several haplotypes of M. acervorum in Europe, with six of them forming a parth…

The Adoption of The Internet of Things by Young Consumers – an Empirical Investigation

2017

On the background of theoretical considerations and literature review, this article presents the results of the preliminary study of young consumers about their adoption of the Internet of Things (IoT) - treated as the emerging technology, creating a new quality of information technology usage, despite perceived costs and privacy concerns. The data for the analysis came from purpose sample of 223 young consumers from Eastern Poland via CAWI questionnaire. The primary goal of the research was to explore the adoption of IoT by young consumers in Poland regarding the level of adoption and factors explaining this phenomenon. The main analysis used univariate analysis of variance (UNIANOVA) and …

Implementare le politiche sanitarie a livello regionale per l'eliminazione dell'epatite C ai tempi del COVID-19

2022

Viral hepatitis C is an important public health problem and its elimination by 2030, defined by the World Health Organization, is an ambitious goal. The chance of free screening for HCV infection represents an important achievement that requires a successful State-Regions coordination and an effective regional organisation, that guarantees an interdisciplinary course between local and specialized healthcare. A structured communication program to increase the sensitivity of target populations as well as health professionals is the key for success. The implementation of the proactive screening, defined by the Milleproroghe Law, is crucial because it will define the tracks for the whole HCV co…

Protección de las víctimas de violencia doméstica: Estudio del Derecho internacional, europeo y comparado de las legislaciones española y alemana

2020

El presente trabajo tiene por objeto analizar producción normativa tanto internacional como europea más relevante en materia de protección de las víctimas de violencia género, en general, y violencia doméstica, en particular. Dicho estudio se lleva a cabo al hilo de la producción legislativa así como procedimientos de control y cooperación internacionales y europeos en la materia. En primer lugar, se analiza la normativa internacional que emana de Naciones Unidas (Convención sobre la Eliminación de Todas las Formas de Discriminación contra la Mujer - CEDAW); en segundo lugar, la del Consejo de Europa (Convenio sobre prevención y lucha contra la violencia contra las mujeres y la violencia do…

Etherification of Functionalized Phenols with Chloroheteroarenes at Low Palladium Loading: Theoretical Assessment of the Role of Triphosphane Ligands…

2011

The present study highlights the potential of robust tridentate ferrocenylphosphanes with controlled conformation as catalytic auxiliaries in CO bond formation reactions. Air-stable palladium triphosphane systems are efficient for selective heteroaryl ether synthesis by using as little as 0.2 mol% of catalyst. These findings represent an economically attractive and clean etherification of functionalized phenols, electron-rich, electron-poor and para-, meta- or ortho-substituted substrates, with heteroaryl chlorides, including pyridines, hydroxylated pyridine, pyrimidines and thiazole. The etherification tolerates very important functions in various positions, such as cyano, methoxy, amino, …

Reazione di eliminazione di Kemp: una sonda per lo studio delle proprietà microscopiche di liquidi ionici

Effect of serum protein binding on pharmacokinetics and anticoagulant activity of phenprocoumon in rats.

1980

The relationship among serum protein binding, kinetics of elimination, distribution, and anticoagulant activity of phenprocoumon was investigated in 25 selected outbred Sprague-Dawley rats which differed in the extent of serum protein binding of this drug. In addition, the serum protein binding of phenprocoumon was altered in inbred Lewis rats by continuous treatment with tolbutamide. This drug was found to displace phenprocoumon from serum proteins without affecting its intrinsic clearance. The serum free fraction values (fs)of the selected Sprague-Dawley rats ranged from 0.0053 to 0.0145. There were positive and linear correlations between fsand the first-order elimination rate constant (…

Analgesic and thermic effects, and cerebrospinal fluid and plasma pharmacokinetics, of intracerebroventricularly administered morphine in normal and …

1998

Abstract The relationship between asthma and opioids has barely been investigated. This study examines whether active sensitization of rats changes the analgesic and thermic effects of intracerebroventricular morphine or the pharmacokinetics of the drug. Morphine (5, 10 and 20 μg) was given intracerebroventricularly to sensitized (active immunization to ovalbumin and Al(OH)3 then airway challenge with ovalbumin after 12 days) and normal (i.e. non-sensitized) male Sprague-Dawley rats. The tail-flick latencies and changes in colon temperature were determined before morphine injection and at 30 min intervals for a period of 300 min afterwards. Results were expressed as the area under the time-…

Disposition of ciprofloxacin following intravenous administration in dogs

1994

The pharmacokinetics of ciprofloxacin (CIP) following intravenous administration in dogs have been investigated. The drug was administered at three doses (2.5, 5 and 10 mg/kg body weight) and was assayed in biological fluid samples (plasma and urine) by an HPLC method. The plasma concentration-time curves were best described by a two-compartment open pharmacokinetic model. The drug was widely distributed (Vd(area) almost 3 l/kg), being distributed in the dog more rapidly than in other species (t1/2(lambda 1) 3 min approximately). The elimination half-life (t1/2 lambda 2) was 129-180 min which is similar to values obtained in other species. The unchanged drug eliminated in urine was less tha…

SARS‐CoV‐2‐reactive interferon‐γ‐producing CD8+ T cells in patients hospitalized with coronavirus disease 2019

2020

Abstract There is limited information on severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) T‐cell immune responses in patients with coronavirus disease 2019 (COVID‐19). Both CD4+ and CD8+ T cells may be instrumental in resolution of and protection from SARS‐CoV‐2 infection. Here, we tested 25 hospitalized patients either with microbiologically documented COVID‐19 (n = 19) or highly suspected of having the disease (n = 6) for presence of SARS‐CoV‐2‐reactive CD69+ expressing interferon‐γ (IFN‐γ) producing CD8+ T cells using flow‐cytometry for intracellular cytokine staining assay. Two sets of overlapping peptides encompassing the SARS‐CoV‐2 Spike glycoprotein N‐terminal 1 to 643 am…
