Mouse models of multiple myeloma: technologic platforms and perspectives.
2018
Murine models of human multiple myeloma (MM) are key tools for the study of disease biology as well as for investigation and selection of novel candidate therapeutics for clinical translation. In the last years, a variety of pre-clinical models have been generated to recapitulate a wide spectrum of biological features of MM. These systems range from spontaneous or transgenic models of murine MM, to subcutaneous or orthothopic xenografts of human MM cell lines in immune compromised animals, to platform allowing the engraftment of primary/bone marrow-dependent MM cells within a human bone marrow milieu to fully recapitulate human disease. Selecting the right model for specific pre-clinical re…
Brain activity during intra- and cross-modal priming: new empirical data and review of the literature
2003
A positron emission tomography (PET) study was conducted to investigate the neurofunctional correlate of auditory within-modality and auditory-to-visual cross-modality stem completion priming. Compared to the auditory-to-auditory priming condition, cross-modality priming was associated with a significantly larger regional cerebral blood flow (rCBF) decrease at the boundary between left inferior temporal and fusiform gyri, brain regions previously associated with modality independent lexical retrieval and reading. Instead, within-modality auditory priming was associated with a bilateral pattern of prefrontal rCBF increase. This was likely the expression of more efficient access to output lex…
Subfascial Endoscopic Perforator Surgery With Tumescent Local Anesthesia
2002
background. Subfascial endoscopic perforator surgery (SEPS) has become an established procedure. objective. To evaluate SEPS with tumescent local anesthesia (TLA) using an single-port device originally designed for that purpose. methods. Patients selected for SEPS received subcutaneous infiltration of TLA into the medial aspect of the calf 20 minutes before surgery. Bipolar coagulation and dissection were used to treat incompetent perforators. results. Fifty-one patients with 67 legs of CEAP stages C3–C6 underwent SEPS with TLA. In 40 patients or 53 legs (79.1%) TLA alone allowed successful completion of the SEPS procedure. Five patients with 7 legs (10.4%) required additional intravenous a…
Verbal suppression and strategy use: a role for the right lateral prefrontal cortex?
2015
Verbal initiation, suppression and strategy generation/use are cognitive processes widely held to be supported by the frontal cortex. The Hayling Test was designed to tap these cognitive processes within the same sentence completion task. There are few studies specifically investigating the neural correlates of the Hayling Test but it has been primarily used to detect frontal lobe damage. This study investigates the components of the Hayling Test in a large sample of patients with unselected focal frontal (n = 60) and posterior (n = 30) lesions. Patients and controls (n = 40) matched for education, age and sex were administered the Hayling Test as well as background cognitive tests. The sta…
THE EFFECT OF SPACED VS. MASSED PRESENTATION OF AGGRESSION ITEMS ON VERBAL AGGRESSIVE RESPONSES OF CHILDREN
1963
A story completion test was constructed and administered to 99 ten-year-old boys. The main results were: (1) The average number of aggressive responses tends to be lower when the aggression items are presented in a ‘spaced’ manner than when they are ‘massed’. (2) There is a spread effect from aggression items to neutral items. Aggression and neutral items presented in mixed order give a stronger effect. (3) A relatively consistent factor structure of aggression responses was shown in the test. Aggression towards peers and authority were independent of each other, and seem to be influenced differently by the manner of presentation of stimuli.
Podstawowe samowartościowanie - walidacja polskiej wersji skali do pomiaru Core Self-Evaluations
2017
Praca przedstawia walidację polskiej wersji skali do pomiaru podstawowego samowartościowania (Core Self-Evaluations – CSES; Judge, Erez, Bono i Thorensen, 2003). Podstawowe samowartościowanie to poglądy danej osoby, dotyczące jej skuteczności, zdolności, wiary we własne siły i pozytywnego nastawienia do siebie i świata. Koncepcja skali jest konstruktem opartym o indywidualne zmienne dyspozycyjne, często badane w kontekście organizacyjnym. Są to: samoocena, wewnętrzne umiejscowienie kontroli, zgeneralizowana samoskuteczność oraz pozytywna afektywność. Na podstawie danych z pięciu badań przeprowadzonych w latach 2014-2016, na łącznie n=3207 osób, w większości pracujących, udało się potwierdzi…
Age and Semantic Inhibition Measured by the Hayling Task: A Meta-Analysis.
2016
Objective Cognitive aging is commonly associated with a decrease in executive functioning (EF). A specific component of EF, semantic inhibition, is addressed in the present study, which presents a meta-analytic review of the literature that has evaluated the performance on the Hayling Sentence Completion test in young and older groups of individuals in order to assess the magnitude of the age effect. Method A systematic search involving Web of Science, PsyINFO, PsychARTICLE, and MedLine databases and Google Scholar was performed. A total of 11 studies were included in this meta-analysis, encompassing a total of 887 participants; 440 young and 447 older adults. The effect sizes for group dif…
The façade-tower of Santa Maria delle Stelle Church in Comiso. Historical events, vulnerability and conservation strategy
2020
Dopo avere richiamato l’estesa vicenda storica della costruzione della chiesa Madre di Santa Maria delle Stelle a Comiso, iniziata nel 1736 e terminata due secoli dopo, il contributo è focalizzato sul tema del completamento della sua facciata con l’uso della struttura intelaia di calcestruzzo di cemento armato, progettata dall’ingegnere Santoro Secolo. In tempi più recenti, alcuni dissesti improvvisi hanno posto in evidenza il tema del rischio e la necessità di interventi per risanare la struttura architettonica. L’importanza del monitoraggio e della manutenzione, intesi come fondamentali strategie di conservazione, concludono l’articolo.
P-matrix completions under weak symmetry assumptions
2000
An n-by-n matrix is called a Π-matrix if it is one of (weakly) sign-symmetric, positive, nonnegative P-matrix, (weakly) sign-symmetric, positive, nonnegative P0,1-matrix, or Fischer, or Koteljanskii matrix. In this paper, we are interested in Π-matrix completion problems, that is, when a partial Π-matrix has a Π-matrix completion. Here, we prove that a combinatorially symmetric partial positive P-matrix has a positive P-matrix completion if the graph of its specified entries is an n-cycle. In general, a combinatorially symmetric partial Π-matrix has a Π-matrix completion if the graph of its specified entries is a 1-chordal graph. This condition is also necessary for (weakly) sign-symmetric …
Choices and Enrollments in French Secondary and Higher Education: Repercussions for Second-Generation Immigrants
2013
En ligne sur http://www.jstor.org/discover/10.1086/670729?uid=16804784&uid=3738016&uid=2129&uid=2134&uid=2&uid=70&uid=3&uid=67&uid=16735408&uid=62&uid=5909928&sid=21102655856551; International audience; In France, the proportion of second-generation immigrants enrolling in tertiary education has increased as education has undergone a process of "democratization." This article analyzes their postsecondary choices, access to tertiary programs, dropout, and transition to the labor market, compared to those of students of French origin. Youths of Portuguese origin are more likely to enter vocational higher programs concordant with their preferences and have better chances of completing a tertia…
