On the relations between parents’ and children’s implicit and explicit academic gender stereotypes.
2017
Although parents may represent influential sources of children’s gender stereotypes, to date no study has directly investigated the relations between parents’ and children’s gender stereotypes regarding academic abilities. Aiming at filling this gap, in the present study parents’ and their young children’s gender stereotypes about math and language were assessed using both explicit and implicit measures for each member of the family. Sixty-eight Italian 6-year-olds, their mothers, and their fathers (a) performed an Implicit Association Test designed to assess implicit gender stereotypes about math and language, and (b) completed a measure of the relevant explicit stereotypes. Fathers’, but …

Slight variations in components ratio affect odor pleasantness of a blending mixture
2009
International audience; Odors rely mainly on the perception of odorants mixtures but are commonly perceived as single undivided entities; nevertheless, the processes involved remain poorly explored. It has been reported that perceptual blending, based on configural olfactory processing, can lead odorant mixtures to give rise to an emergent odor quality not present in the components. Furthermore, very slight variations (just noticeable differences, jnd) in components concentrations were shown to be sufficient to modify the odor quality of a blending mixture. In the present study, we set out to examine whether jnd in components concentrations could also affect the odor pleasantness of a blend…
Transcranial Magnetic Stimulation Trains at 1 Hz Frequency of the Right Posterior Parietal Cortex Facilitate Recognition Memory
2021
Neuroimaging, neuropsychological, and brain stimulation studies have led to contrasting findings regarding the potential roles of the lateral parietal lobe in episodic memory. Studies using brain stimulation methods reported in the literature do not offer unequivocal findings on the interactions with stimulation location (left vs. right hemisphere) or timing of the stimulation (encoding vs. retrieval). To address these issues, active and sham 1 Hz repetitive transcranial magnetic stimulation (rTMS) trains of 600 stimuli were applied over the right or left posterior parietal cortex (PPC) before the encoding or before the retrieval phase of a recognition memory task of unknown faces in a grou…
Haptic Perception in Extreme Obesity: qEEG Study Focused on Predictive Coding and Body Schema
2020
Haptic perception (HP) is a perceptual modality requiring manual exploration to elaborate the physical characteristics of external stimuli through multisensory integrative cortical pathways. Cortical areas exploit processes of predictive coding that collect sensorial inputs to build and update internal perceptual models. Modifications to the internal representation of the body have been associated with eating disorders. In the light of this, obese subjects were selected as a valid experimental model to explore predictive coding in haptic perception. To this purpose, we performed electroencephalographic (EEG) continuous recordings during a haptic task in normally weighted versus obese subjec…
Spouses’ Experiences of Rehabilitees’ Burnout and Recovery
2021
The role of family members’ support in the burnout recovery process has been recognized in several studies. The role of emotional support provided by the spouse has been found to be significant in reducing burnout levels. Although crossover of burnout and emotional support have been investigated, the partners’ experiences of the individuals’ burnout and recovery have remained largely unexplored. To fill this research gap the study aims to provide in-depth knowledge of the experiences of spouses of individuals who have a history of burnout and are recovering from it by participating in a rehabilitation course. Ten spouses of individuals who had previously suffered and had recovered or was re…
Synthesis and Antitumor Evaluation of Menthone-Derived Pyrimidine-Urea Compounds as Potential PI3K/Akt/mTOR Signaling Pathway Inhibitor.
2022
A series of novel menthone derivatives bearing pyrimidine and urea moieties was designed and synthesized to explore more potent natural product-derived antitumor agents. The structures of the target compounds were confirmed by FTIR, NMR, and HRMS. The in vitro antitumor activity was tested by standard methyl thiazolytetrazolium assay and showed that 4i, 4g, 4s, and 4m are the best compounds with IC50 values of 6.04 ± 0.62µM, 3.21 ± 0.67µM, 19.09 ± 0.49µM, and 18.68 ± 1.53µM, against Hela, MGC-803, MCF-7, and A549, respectively. The results of the preliminary action mechanism studies showed that compound 4i, the representative compound, could induce cell apoptosis in Hela cells in a dose-dep…
Disrupted Spatial Organization of Cued Exogenous Attention Persists Into Adulthood in Developmental Dyslexia
2021
Purpose: Abnormal exogenous attention orienting and diffused spatial distribution of attention have been associated with reading impairment in children with developmental dyslexia. However, studies in adults have failed to replicate such relationships. The goal of the present study was to address this issue by assessing exogenous visual attention and its peripheral spatial distribution in adults with developmental dyslexia.Methods: We measured response times, accuracy and eye movements of 18 dyslexics and 19 typical readers in a cued discrimination paradigm, in which stimuli were presented at different peripheral eccentricities.Results: Results showed that adults with developmental dyslexia…
Mtlinteracts with members of Egfr signaling and cell adhesion genes in the Drosophila eye
2011
Mtl is a member of the Rho family of small GTPases in Drosophila. It was shown that Mtl is involved in planar cell polarity (PCP) establishment, together with other members of the same family like Cdc42, Rac1, Rac2 and RhoA. However, while Rac1, Rac2 and RhoA function downstream of Dsh in Fz/PCP signaling and upstream of a JNK cassette, Mtl and Cdc42 do not. To determine the functional context of Mtl during PCP establishment in the Drosophila eye, we performed a loss-of-function screen to search for dominant modifiers of a sev>Mtl rough eye phenotype. In addition, genetic interaction assays with candidate genes were also carried out. Our results show that Mtl interacts genetically with memb…
