Apoptotic-like Leishmania exploit the host´s autophagy machinery to reduce T-cell-mediated parasite elimination
2015
Apoptosis is a well-defined cellular process in which a cell dies, characterized by cell shrinkage and DNA fragmentation. In parasites like Leishmania, the process of apoptosis-like cell death has been described. Moreover upon infection, the apoptotic-like population is essential for disease development, in part by silencing host phagocytes. Nevertheless, the exact mechanism of how apoptosis in unicellular organisms may support infectivity remains unclear. Therefore we investigated the fate of apoptotic-like Leishmania parasites in human host macrophages. Our data showed--in contrast to viable parasites--that apoptotic-like parasites enter an LC3(+), autophagy-like compartment. The compartm…

Suomalaisten käsityksiä maatalousmaiseman muutoksesta ja maatalouden ekosysteemipalveluista
2015
Tutkimuksen tarkoituksena on suomalaisten maatalousmaisemaan ja maatalouden ekosysteemipalveluihin liittyvien käsitysten tutkiminen. Maatalousmaisema on Suomessa jatkuvassa muutoksessa, ja maisemaan liittyvät näkemykset ovat usein ristiriidassa keskenään. Suomen ratifioiman eurooppalaisen maisemayleissopimuksen mukaan kansalaisten maisema-arvostuksia tulisi huomioida maisemaa koskevassa suunnittelussa ja päätöksenteossa. Maatalousmaisemaa voidaan lähestyä myös sen tarjoamien ekosysteemipalvelujen eli hyötyjen avulla. Tutkimuksessa tarkastellaan, mitä ekosysteemipalveluja ja minkä verran suomalaiset arvioivat maatalousmaiseman tuottavan. Lisäksi tutkitaan, miten kansalaiset yhtäältä ennakoiv…
La macchina scenotecnica della visione: Robert Lepage e la sintesi tra meccanica e digitale nella messa in scena del Der ring des Nibelungen
2018
Robert Lepage impiega sulla sua scena tutti i dispositivi scenotecnici possibili, siano essi meccanici, elettrici o digitali, operando spesso con tecnologie che ricordano per la loro funzione le macchine scenotecniche del passato. Uno dei dispositivi più utilizzati da Robert Lepage, che connota gran parte della sua produzione, è la macchina girevole che costantemente modifica in tempo reale la scena. La macchina rotante non è però l’unico dispositivo che Lepage rimedia dalla scenotecnica teatrale. Muovendosi in una sorta di neo-barocco tecnologico, infatti, attinge a tutti quei dispositivi e macchine perfezionati nel XVII secolo da scenotecnici italiani, ibridandoli con nuove forme di dispo…
Sneaking into a Hotspot of Biodiversity: Coverage and Integrity of a Rhodolith Bed in the Strait of Sicily (Central Mediterranean Sea)
2022
Habitat mapping, physical characteristics and benthic community of a rhodolith bed in the Pelagie Islands (Strait of Sicily, Mediterranean Sea) were studied through Multi–Beam Echo–Sounder (MBES), Remotely Operated Vehicle (ROV) and grab samples. The geomorphological analysis revealed an articulated and wide rhodolith bed; video inspections highlighted a bed with high coverage, few sandy patches and with a prevalence of the boxwork morphotype. A total of 207 taxa with 876 specimens were identified, and Polychaeta was the dominant taxon. Linguimaera caesaris, a Lessepsian benthic amphipod, was recorded in all sampling sites, and its presence represents an input to deepen the benthic assembla…
Bilateral activations in operculo‐insular area show temporal dissociation after peripheral electrical stimulation in healthy adults
2018
Interhemispheric transfer is necessary for sensory integration and coordination of body sides. We studied how somatosensory input from one body side may reach both body sides. First, we investigated with 17 healthy adults in which uni‐ and bilateral brain areas were involved in consecutive stages of automatic sensory processing of non‐nociceptive peripheral stimulation. Somatosensory evoked fields (SEFs) to electrical stimulation were recorded with 306‐channel magnetoencephalography in two conditions. First, SEFs were registered following sensory radial nerve (RN) stimulation to dorsal surface of the right hand and second, following median nerve (MN) stimulation at the right wrist. Cortical…
More comprehensive proprioceptive stimulation of the hand amplifies its cortical processing
2021
Corticokinematic coherence (CKC) quantifies the phase coupling between limb kinematics and cortical neurophysiological signals reflecting proprioceptive feedback to the primary sensorimotor (SM1) cortex. We studied whether the CKC strength or cortical source location differs between proprioceptive stimulation (i.e., actuator-evoked movements) of right-hand digits (index, middle, ring, and little). Twenty-one volunteers participated in magnetoencephalography measurements during which three conditions were tested: 1) simultaneous stimulation of all four fingers at the same frequency, 2) stimulation of each finger separately at the same frequency, and 3) simultaneous stimulation of the fingers…
Identification of proprioceptive thalamocortical tracts in children: comparison of fMRI, MEG, and manual seeding of probabilistic tractography
2022
Publisher Copyright: © The Author(s) 2022. Published by Oxford University Press. Studying white matter connections with tractography is a promising approach to understand the development of different brain processes, such as proprioception. An emerging method is to use functional brain imaging to select the cortical seed points for tractography, which is considered to improve the functional relevance and validity of the studied connections. However, it is unknown whether different functional seeding methods affect the spatial and microstructural properties of the given white matter connection. Here, we compared functional magnetic resonance imaging, magnetoencephalography, and manual seedin…

Exploring Oscillatory Dysconnectivity Networks in Major Depression During Resting State Using Coupled Tensor Decomposition
2022
Dysconnectivity of large-scale brain networks has been linked to major depression disorder (MDD) during resting state. Recent researches show that the temporal evolution of brain networks regulated by oscillations reveals novel mechanisms and neural characteristics of MDD. Our study applied a novel coupled tensor decomposition model to investigate the dysconnectivity networks characterized by spatio-temporal-spectral modes of covariation in MDD using resting electroencephalography. The phase lag index is used to calculate the functional connectivity within each time window at each frequency bin. Then, two adjacency tensors with the dimension of time frequency connectivity subject are constr…
