Different Scales of Spatial Segregation of Two Species of Feather Mites on the Wings of a Passerine Bird

2011

The "condition-specific competition hypothesis" proposes that coexistence of 2 species is possible when spatial or temporal variations in environmental conditions exist and each species responds differently to those conditions. The distribution of different species of feather mites on their hosts is known to be affected by intrinsic host factors such as structure of feathers and friction among feathers during flight, but there is also evidence that external factors such as humidity and temperature can affect mite distribution. Some feather mites have the capacity to move through the plumage rather rapidly, and within-host variation in intensity of sunlight could be one of the cues involved …

Papillote and Piopio:DrosophilaZP-domain proteins required for cell adhesion to the apical extracellular matrix and microtubule organization

2005

Adhesion between epithelial cells and extracellular substrates is normally mediated through basal adhesion complexes. However, some cells also possess comparable junctions on their apical surface. Here, we describe two new Drosophila proteins, Piopio and Papillote, that are required for the link between the apical epithelial surface and the overlying apical extracellular matrix (aECM). The two proteins share a zona pellucida (ZP) domain with mammalian aECM components, including the tectorins found in the vertebrate inner ear. Tagged versions of both proteins localized to the apical epithelial surface. Mutations in piopio, papillote and dumpy (another gene encoding a ZP-domain protein) cause…

Voila, a New Drosophila Courtship Variant that Affects the Nervous System: Behavioral, Neural, and Genetic Characterization

1998

InDrosophila melanogaster, a specificPGAL4transposon induces theVoila1genetic variant and produces multiple phenotypes. HomozygousVoila1/1flies rarely reach adulthood, whereas heterozygousVoila1/+adult males show strong bisexual behavior. Males with a single copy ofVoila1driving the feminizing transgeneUAS-transformershow very reduced sexual activity but no overall effect on their behavior.Voila1is specifically expressed in the nervous system. In the CNS, it is expressed mainly in the mushroom bodies and, to a lesser extent, in the antennal lobes. In the peripheral nervous system, GAL4 expression is almost entirely restricted to the gustatory sensilla. Using chromosomal deficiencies, the be…

Modulation of Hedgehog target gene expression by the Fused serine-threonine kinase in wing imaginal discs

1998

0925-4773 doi: DOI: 10.1016/S0925-4773(98)00130-0; The Fused (Fu) serine–threonine kinase and the Suppressor of fused (Su(fu)) product are part of the Hedgehog (Hh) signalling pathway both in embryos and in imaginal discs. In wing imaginal discs, the Hh signal induces Cubitus interruptus (Ci) accumulation and activates patched (ptc) and decapentaplegic (dpp) expression along the anterior/posterior (A/P) boundary. In this paper, we have examined the role of the Fu and Su(fu) proteins in the regulation of Hh target gene expression in wing imaginal discs, by using different classes of fu alleles and an amorphic Su(fu) mutation. We show that, at the A/P boundary, Fu kinase activity is involved …

Accuracy of Nasal Pressure Swing to Predict Failure of High-Flow Nasal Oxygen in Patients with Acute Hypoxemic Respiratory Failure

2023

In a real-life cohort of patients with AHRF undergoing HFNO, ΔPnose showed excellent accuracy in predicting early failure, similar of that displayed by ROX. Giving that the decision to upgrade to NIV or MV was based on clinical variables, the high accuracy of ROX in predicting failure of HFNO is not surprising. The similar accuracy of ΔPnose (the only measurement that remained blinded to our clinical decision), strengthened the association with outcome, avoiding incorporation bias.

I disegni di Rosario Gagliardi conservati presso il Dipartimento di Architettura di Palermo

2020

The Department of Architecture of Palermo keeps some drawings related to the activity of one of the greatest architects to have worked in Sicily in the eighteenth century: Rosario Gagliardi (Syracuse, ca. 1690-Noto, 1762). The importance of the small corpus - coming from a collection already constituted in the 18th century (the Mazza Collection) - is also linked to the fact that the drawings include famous edifices of Sicilian Baroque architecture: from the cathedral of San Giorgio in Ragusa to the churches of Santa Chiara and San Domenico in Noto. The thorough examination of the drawings offers the opportunity for a more general reflection on the characteristics of architectural design in …

Nasal pressure swings as the measure of inspiratory effort in spontaneously breathing patients with de novo acute respiratory failure.

2022

Abstract Background Excessive inspiratory effort could translate into self-inflicted lung injury, thus worsening clinical outcomes of spontaneously breathing patients with acute respiratory failure (ARF). Although esophageal manometry is a reliable method to estimate the magnitude of inspiratory effort, procedural issues significantly limit its use in daily clinical practice. The aim of this study is to describe the correlation between esophageal pressure swings (ΔPes) and nasal (ΔPnos) as a potential measure of inspiratory effort in spontaneously breathing patients with de novo ARF. Methods From January 1, 2021, to September 1, 2021, 61 consecutive patients with ARF (83.6% related to COVID…

E allora c’è l’uso della tipografia per la composizione del testo, in forma concisa di pensieri sparsi o più strutturata di riflessioni ampie, necessarie per tenere insieme la mente e la mano, per verificare la direzione presa e correggere la rotta se necessario. C’è l’uso del progetto grafico, che di strumenti ne richiede diversi, la tipografia in primis, ma anche le forme, i colori, e poi le gerarchie, le relazioni, e su tutti la traduzione dei contenuti, un continuo processo di mediazione. C’è infine l’uso del disegno, che ha bisogno davvero di pochi strumenti per esistere, un foglio e un pennino, ovvero un piano su cui depositare una bava di inchiostro e uno in grado di spargerlo sulla …
