Integrative taxonomy demonstrates the unexpected synonymy between two predatory mite species: Cydnodromus idaeus and C. picanus (Acari: Phytoseiidae)
2011
Contact: tixier@supagro.inra.fr; Species of the mite family Phytoseiidae are well known as predators of mite pests all over the world. Their identification is thus of great interest for biological control. The specimens examined in this study belong to the species Cydnodromus idaeus (described from Brazil) and C. picanus (described from Chile). They were collected together on the same plant in Argentina. These species are mainly differentiated by the presence/absence of the dorsal solenostomes (gland openings) gd2. Some morphometric differences were observed between the Argentinian specimens and the type material of C. idaeus and C. picanus; however, they were not sufficient to support a sp…
Plant communities of the Czerwona Woda River Valley (Stołowe Mountains National Park)
2018
Abstract The Czerwona Woda River is the main watercourse in the Stołowe Mountains National Park and drains the major part of the Stołowe Mts. It was regulated in the past, but its channel has been spontaneously naturalised. Now, managed spruce forests grow along almost the entire length of this small mountain stream. The aims of the present study were to investigate diversity of plant communities connected with the Czerwona Woda stream and to prepare detailed vegetation maps. The results obtained can potentially be a reference for future restoration projects implemented in the Stołowe Mountains National Park. As a result of vegetation mapping, there were distinguished 20 plant communities r…
The EP300/TP53 pathway, a suppressor of the Hippo and canonical WNT pathways, is activated in human hearts with arrhythmogenic cardiomyopathy in the …
2021
Aim Arrhythmogenic cardiomyopathy (ACM) is a primary myocardial disease that typically manifests with cardiac arrhythmias, progressive heart failure and sudden cardiac death (SCD). ACM is mainly caused by mutations in genes encoding desmosome proteins. Desmosomes are cell-cell adhesion structures and hubs for mechanosensing and mechanotransduction. The objective was to identify the dysregulated molecular and biological pathways in human ACM in the absence of overt heart failure. Methods and results Transcriptomes in the right ventricular endomyocardial biopsy samples from three independent individuals carrying truncating mutations in the DSP gene and 5 control samples were analyzed by RNA-S…
Chronically elevated branched chain amino acid levels are pro-arrhythmic.
2022
Aim. Cardiac arrhythmias comprise a major health and economic burden and are associated with significant morbidity and mortality, including cardiac failure, stroke and sudden cardiac death (SCD). Development of efficient preventive and therapeutic strategies is hampered by incomplete knowledge of disease mechanisms and pathways. Our aim is to identify novel mechanisms underlying cardiac arrhythmia and SCD using an unbiased approach. Methods and Results. We employed a phenotype-driven N-ethyl-N-nitrosourea (ENU) mutagenesis screen and identified a mouse line with a high incidence of sudden death at young age (6-9 weeks) in the absence of prior symptoms. Affected mice were found to be homozyg…
L’ A B S I D E. COSTRUZIONE E GEOMETRIE
2015
Le absidi costituiscono solitamente la prima parte di una fabbrica che viene posta in opera. L'aspettativa di tempi lunghi del cantiere spinge a realizzare immediatamente opere fastose e decorate in grado di gratificare committenti che non vedranno mai conclusi i lavori. Dal punto di vista geometrico i progetti prodotti nell'Europa del Sud hanno seguito, nei secoli, schemi per lo più convenzionali (strutture semicircolari, quadrangolari o generate da poligoni ottagonali) ma non mancano le eccezioni e i tentativi di definire soluzioni alternative (valgano per tutte la struttura treboladas castigliane, la scelta di usare l'abside come base per un campanile o le conformazioni derivanti da poli…

Association of Left Ventricular Systolic Dysfunction Among Carriers of Truncating Variants in Filamin C With Frequent Ventricular Arrhythmia and End-…
2021
Importance: Truncating variants in the gene encoding filamin C (FLNCtv) are associated with arrhythmogenic and dilated cardiomyopathies with a reportedly high risk of ventricular arrhythmia.Objective: To determine the frequency of and risk factors associated with adverse events among FLNCtv carriers compared with individuals carrying TTN truncating variants (TTNtv).Design, Setting, and Participants: This cohort study recruited 167 consecutive FLNCtv carriers and a control cohort of 244 patients with TTNtv matched for left ventricular ejection fraction (LVEF) from 19 European cardiomyopathy referral units between 1990 and 2018. Data analyses were conducted between June and October, 2020.Main…
Unexpected death for Takayasu aortitis associated with coronary ostial stenosis: case report.
2015
The differential diagnosis of vasculitis is often a difficult task due to the frequent morphological similarities that various vasculitic syndromes express when the heart is the target organ. The more the lesions are limited to the arterial tree with absent or almost silent coronary events, the less specific the anatomical and clinical frameworks. To create a series of clinical records and on the basis of these assumptions, the authors report a case concerning the sudden death of a 43-year-old woman which occurred while an ergonometric test was being carried out 28 days after the onset of the symptoms. A subsequent postmortem investigation/autopsy enabled us to detect a granulomatous aortit…
Anatomical features and clinical correlations in Caucasian patients with definite arrhythmogenic right ventricular dysplasia/cardiomyopathy.
2014
AIM: Arrhythmogenic right ventrticular dysplasia/cardiomyopathy (ARVD/C) is an inherited cardiomyopathy characterized by fibrofatty replacement and a high risk of ventricular arrhythmias (VA) and sudden cardiac death (SCD). The aim of the present investigation is to examine the pathological profile and the clinical correlations in a group of ARVD/C patients. METHODS: We conducted a multicenter study evaluating 47 patients (31 men; mean age 37±14 years) with definite ARVD/C. Diagnosis was established according to the actual clinicomorphologic criteria at autopsy or clinically. We divided the study population in 2 different groups. First group included 28 alive patients and the second 19 pati…
Serial echocardiographic left ventricular ejection fraction measurements: A tool for detecting thalassemia major patients at risk of cardiac death
2013
Cardiac damage remains a major cause of mortality among patients with thalassemia major. The detection of a lower cardiac magnetic resonance T2* (CMR-T2*) signal has been suggested as a powerful predictor of the subsequent development of heart failure. However, the lack of worldwide availability of CMR-T2* facilities prevents its widespread use for follow-up evaluations of cardiac function in thalassemia major patients, warranting the need to assess the utility of other possible procedures. In this setting, the determination of left ventricular ejection fraction (LVEF) offers an accurate and reproducible method for heart function evaluation. These findings suggest a reduction in LVEF≥7%, ov…
