Pełna trójnaczyniowa rewaskularyzacja wieńcowa z użyciem ultra niskich dawek kontrastu jako strategia zachowania rezydualnej funkcji nerek u chorego …
2018
Nefropatia indukowana kontrastem jest poważnym powikłaniem koronarografii i przezskórnych interwencji wieńcowych (PCI) u chorych z przewlekłymi schorzeniami nerek. Jedyną realną strategią zapobiegawczą przed jej rozwojem jest adekwatne nawodnienie wraz z ograniczeniem objętości stosowanego kontrastu. Ostatnio zaproponowano nowe techniki diagnostyczne i terapeutyczne polegające na stosowaniu ultra niskich dawek kontrastu, co więcej opisano zabiegi PCI bez użycia kontrastu. W niniejszym artykule prezentujemy przypadek dializowanego chorego z ostrym zespołem wieńcowym i ciężką niewydolnością jedynej nerki, ale z zachowaną rezydualną jej funkcją, u którego przeprowadzono diagnostykę i pełną tró…
A Low Dose of Pure Cannabidiol Is Sufficient to Stimulate the Cytotoxic Function of CIK Cells without Exerting the Downstream Mediators in Pancreatic…
2022
Despite numerous studies conducted over the past decade, the exact role of the cannabinoid system in cancer development remains unclear. Though research has focused on two cannabinoid receptors (CB1, CB2) activated by most cannabinoids, CB2 holds greater attention due to its expression in cells of the immune system. In particular, cytokine-induced killer cells (CIKs), which are pivotal cytotoxic immunological effector cells, express a high-level of CB2 receptors. Herein, we sought to investigate whether inducing CIK cells with cannabidiol can enhance their cytotoxicity and if there are any possible counter effects in its downstream cascade of phosphorylated p38 and CREB using a pancreatic d…
β and γ bands in N = 88, 90, and 92 isotones investigated with a five-dimensional collective Hamiltonian based on covariant density functional theory…
2019
A comprehensive systematic study is made for the collective β and γ bands in even-even isotopes with neutron numbers N=88 to 92 and proton numbers Z=62(Sm) to 70 (Yb). Data, including excitation energies, B(E0) and B(E2) values, and branching ratios from previously published experiments are collated with new data presented for the first time in this study. The experimental data are compared to calculations using a five-dimensional collective Hamiltonian (5DCH) based on the covariant density functional theory (CDFT). A realistic potential in the quadrupole shape parameters V(β,γ) is determined from potential energy surfaces (PES) calculated using the CDFT. The parameters of the 5DCH are fixe…
Muon-electron lepton-flavor-violating transitions : Shell-model calculations of transitions in 27Al
2018
In this paper we present the results of large-scale shell-model calculations of muon-to-electron lepton-flavorviolating transitions for the case of the target nucleus 27Al. We extend the previous shell-model calculations, done in the sd model space, by including also the p orbitals in order to see whether the negative-parity states produce any significant effect in the conversion rate. The analysis of the results shows the dominance of coherent transitions mediated by isovector operators and going by the ground state of the target, with practically null influence of excited positive- or negative-parity states. peerReviewed
Documenting Italo-Romance minority languages in the Americas. Problems and tentative solutions
2021
This article describes the process of preparation and implementation of a data collection enterprise targeting Italo-Romance emigrant languages in North and South America. This data collection is part of the ERC Microcontact project, which aims to understand language change in contact by examining the language of Italian communities in the Americas.

Activation of Grapevine Defense Mechanisms: Theoretical and Applied Approaches
2011
part 4.; International audience; Grapevine, as other plants, possesses an innate immune system that usually prevents infection by pathogens. General elicitors are compounds of different biochemical families capable of inducing plant defense reactions. In grapevine, the cascade of defense events induced by elicitors has been studied among others in cell suspensions. The perception of the elicitor triggers signaling events that allow the activation of defense genes encoding PR proteins and other proteins involved in phytoalexin production and cell wall reinforcement. The grapevine phytoalexins resveratrol and derivated compounds have been largely studied. In addition to their antimicrobial ac…
The role of maternal effects in host-parasite interactions: examination of the development of the immune defense in a colonial seabird, the black-leg…
2004
One of the main aims of evolutionary biology is to understand the mechanisms responsible for the phenotypic variation on which natural selection can act. Maternal effects occur when a mother's phenotype or her environment influence her offspring's phenotype. Despite the importance of such effects for the ecology of host-parasite interactions, their role has been relatively neglected to date. In this thesis, we examined how mothers influence the immune defense of their young in an environment that varies in space and time. This work has primarily focused on a colonial seabird, the black-legged kittiwake (Rissa tridactyla). Using this model, we have first shown that specific maternal antibodi…
Measurement of activity of the predominant gamma-emitting radionuclides in activated components of a medical cyclotron plan
2008
An identification and activity evaluation of the predominant gamma-emitting radionuclides in activated parts of a medical cyclotron plant by high resolution gamma-ray spectrometry were performed. The use of LaBr3:Ce scintillation and HPGe detectors was examined in order to solve the measurement problems due to high activity of some components used inside a plant provided with an IBA CYCLONE 18/9 cyclotron. For each component, the identification of some key-radionuclides allows to evaluate the surface dose behaviour as function of decay time. The largest activity values are related to radionuclides with half-life of 70-80 days, while radionuclides with higher half-lives represent less than 1…
