Cultura figurativa popolare. Suoi usi e riusi
2021
Il saggio, dopo una ricognizione della riflessione sulla nozione di arte popolare in ambito demoetnoantropologico, con particolare riferimento all'orizzonte figurativo in Sicilia, su sofferma su alcuni esempi della produzione contemporanea di oggetti che hanno assunto figurazioni proprie del repertorio della pittura del carro e come questo comporti un ripensamento del rapporto "langue"/"parole" del fare artistico popolare che diventa un "brand". The essay, after a survey of the reflection on the notion of popular art in the demo-ethno-anthropological field, with particular reference to the figurative horizon in Sicily, focuses on some examples of the contemporary production of objects that …
Actividad en membranas modelo de péptidos apoptóticos
2017
Los fragmentos mínimos de Bax son capaces de reproducir la actividad permeabilización de membranas de la proteína, incluyendo la capacidad de liberar el citocromo c del interior de las mitocondrias y de activar la apoptosis en las células. Estos hechos significan que la actividad de la proteína puede ser vista como la adición de actividades de sus partes constituyentes, que además es la base de cualquier estrategia reduccionista para investigar sistemas complejos. Sin embargo, el mecanismo molecular de acción de los fragmentos de la proteína Bax es poco conocido. En particular, aunque la especie activa de Bax en la membrana es un oligómero, el estado de agregación de los fragmentos activos …
Protein recovery as a resource from waste specifically via membrane technology : from waste to wonder
2021
Economic growth and the rapid increase in the world population has led to a greater need for natural resources, which in turn, has put pressure on said resources along with the environment. Water, food, and energy, among other resources, pose a huge challenge. Numerous essential resources, including organic substances and valuable nutrients, can be found in wastewater, and these could be recovered with efficient technologies. Protein recovery from waste streams can provide an alternative resource that could be utilized as animal feed. Membrane separation, adsorption, and microbe-assisted protein recovery have been proposed as technologies that could be used for the aforementioned protein re…
Dental treatment of patients with coagulation factor alterations: An update
2007
Hemostasia is a defense mechanism that protects vascular integrity, avoids blood loss, and maintains blood fluidity throughout the circulatory system. The biochemical processes leading to blood clot formation are complex, and alterations can appear at any point within the chain of events. While a range of alterations can affect the coagulation factors, some are more common than others in the general population, including congenital (hemophilia A and B, Von Willebrand’s disease) and acquired disorders (anticoagulant drugs). Such diseases require special consideration in the context of dental treatment, and therefore must be known to dental professionals. Interconsultation with the hematologi…
Attitudes and related perceptions about product placement: a comparison of Finland, Italy and the United States
2015
The primary goal of our study is to explore cross-national differences in attitudes and perceptions about product placements, after investigating measurement invariance. Our cross-national focus includes three countries that have not been compared previously: Finland, Italy and the USA, which differ significantly in terms of the evolution/maturity of product placement markets, regulatory structures and cultural contexts. Motivated by earlier studies, we investigate the cross-national measurement invariance of scales to measure four research constructs related to the product placement domain (attitude toward credibility of advertising, attitude toward advertising-in-general, attitude toward …
Personal branding or employee advocacy : expert's use of social networking site
2017
This paper deals with social media in building experts’ professional images. In the theoretical part, online communities are discussed in the light of the paper’s topic. The study relies on technological adoption models, and in particular, the UTAUT (Unified Theory of Acceptance and Use of Technology) 2 model. In the empirical part, the use of LinkedIn was analyzed as the major tool for professional networking. Our research results suggest that the use of LinkedIn has been initiated mostly by invitation or encouragement of another user. Only in rare occasions, self-branding was reported as the primary motivation to register into LinkedIn. Self-presentation was improved in the process of usi…
Employer brand management: methodological aspects
2021
У статті обгрунтовано необхідність залучення зовнішніх ресурсів для управління брендом роботодавця. У роботі авторами було схематизовано процес прийняття рішення щодо обгрунтованого вибору компаній аутсорсерів. При цьому сформовано систему критеріїв здійснення такого вибору, що включає як вимоги до компанії-аутсорсера, так і вимоги до майбутнього проекту: рівень вдалих попередніх проектів; рівень задоволеності клієнтів; досвід роботи в Україні; середня вартість послуг аутсорсингової компанії з розробки проекту; термін розробки проекту; комплексність розроблених рекомендацій щодо просування бренду роботодавця; термін дії проекту; гнучкість проекту; рівень складності впровадження проекту; сер…
Phasor-FLIM for a direct investigation of Transportan 10 interactions with model membranes
2023
Transportan 10 (TP10), a short and positive charged peptide, belonging to the family of the cell penetrating peptides has gained increasing attention for its antimicrobial and anticancer activity but also for its applications in drug delivery as it is able to translocate therapeutic molecules in cellular environment. Due to the complexity of the phenomena involved in cellular uptake and following processes, which strongly depend on the membrane lipid composition, structural details of the peptide (e.g., charge, hydrophobicity, steric hindrance) and environmental conditions, it is not easy to understand the general rules governing them. Here, we combine spectroscopic techniques and fluoresce…
Molecular mechanisms underlying proteins-membrane interaction
Exploring fast proton transfer events associated with lateral proton diffusion on the surface of membranes
2019
Proton diffusion (PD) across biological membranes is a fundamental process in many biological systems, and much experimental and theoretical effort has been employed for deciphering it. Here, we report on a spectroscopic probe, which can be tightly tethered to the membrane, for following fast (nanosecond) proton transfer events on the surface of membranes. Our probe is composed of a photoacid that serves as our light-induced proton source for the initiation of the PD process. We use our probe to follow PD, and its pH dependence, on the surface of lipid vesicles composed of a zwitterionic headgroup, a negative headgroup, a headgroup that is composed only from the negative phosphate group, or…
