Hydrothermal Aging of an Epoxy Resin Filled with Carbon Nanofillers
2020
The effects of temperature and moisture on flexural and thermomechanical properties of neat and filled epoxy with both multiwall carbon nanotubes (CNT), carbon nanofibers (CNF), and their hybrid components were investigated. Two regimes of environmental aging were applied: Water absorption at 70 °
Calculations of organic-solvent dispersions of single-wall carbon nanotubes
2005
The aqueous solubility Sw and 1-octanol–(Po), cyclohexane–(Pch), and chloroform–(Pcf) water partition coefficients are calculated. The properties of single-wall carbon nanotubes (SWNT) are related to the indices (n, m) designating the chiral vector. SWNTs are classified in zigzag (n, 0), armchair (n, n), and chiral (n, m). These properties permit classifying SWNTs according to (n, m). Correlations between (n2 + nm + m2)1/2, log Sw, log Po, log Pch, and log Pcf show that (n, m) are adequate indices. The (10,10) is the most abundant SWNT, presenting consistency between great kinetic stability, small Sw, and great {Po, Pch, Pcf}. The room temperature solubility of SWNTs is investigated in a va…
On the adenosintriphosphatase activity of the particulates of the egg of the sea urchinParacentrotus lividus
1957
I particolati delle uova vergini di riccio di mare possono essere separati, a mezzo della centrifugazione differenziale, in due frazioni, una fortemente ed una scarsamente pigmentata. La prima mostra una attivita ATPasica attivata da Mg con un massimo a pH 8.2; il massimo della seconda e invece a pH 6.4. Nelle preparazioni contenenti i due tipi di particolati si ritrovano i due massimi.
The Children of Risk Communication
2022
For the management of the COVID-19 pandemic, risk communication has been a much-needed preventive and educative action to support citizens – including children – to adopt preventive and health protective measures. However, the COVID-19 pandemic is not the only health concern at hand that has raised concerns about the health status of children and required disease-preventive strategies. Bearing in mind the mental health problems and learning losses reported during the pandemic, in this commentary, we will argue that by now, it is time to consider critically if there could be more space for positive communication and education, both alongside and as an integral part of risk communication, to…
‘La chiamiamo con entrambi i nomi’: eponimia ed eteronimia tra Nemesis e Adrasteia
2020
Prendendo le mosse da un passo di Ammiano Marcellino (XIV 11,25), che lascia emergere un’evidente sovrapposizione tra la figura di Adrasteia e quella Nemesis, il contributo si propone di esaminare le ragioni che hanno condotto le due potenze ad essere indicate l’una come l’eteronimo dell’altra. A partire dalle fonti di V secolo fino alla paremiografia e alla lessicografia di età imperiale si ricostruisce un percorso che si propone di mostrare gli accidenti e le molteplici variabili cui le logiche di denominazione del divino, nel mondo greco, possono essere soggette. Starting from a passage by Ammiano Marcellino (XIV 11,25), which reveals an evident overlap between the figure of Adrasteia an…
Combination of the mTOR inhibitor ridaforolimus and the anti-IGF1R monoclonal antibody dalotuzumab: preclinical characterization and phase I clinical…
2014
Abstract Purpose: Mammalian target of rapamycin (mTOR) inhibition activates compensatory insulin–like growth factor receptor (IGFR) signaling. We evaluated the ridaforolimus (mTOR inhibitor) and dalotuzumab (anti-IGF1R antibody) combination. Experimental Design: In vitro and in vivo models, and a phase I study in which patients with advanced cancer received ridaforolimus (10–40 mg/day every day × 5/week) and dalotuzumab (10 mg/kg/week or 7.5 mg/kg/every other week) were explored. Results: Preclinical studies demonstrated enhanced pathway inhibition with ridaforolimus and dalotuzumab. With 87 patients treated in the phase I study, main dose-limiting toxicities (DLT) of the combination were p…
Inflammatory Pseudotumor of Mediastinum Treated with Tomotherapy and Monitored with FDG-PET/CT: Case Report and Literature Review
2010
Mediastinal inflammatory pseudotumor is a rare disease with reactive pseudoneoplastic features and a proven capacity for local invasion. The radiographic appearance of inflammatory pseudotumor is quite non-specific and the definitive diagnosis is based on the histological evaluation of tissue specimens. Resection of the lesion is the treatment of choice. However, nonsurgical treatments such as radiotherapy and steroids have been employed in the setting of incomplete surgical resection, tumor recurrence, and patients being unfit for surgery. The case described here is being reported because of the rare mediastinal location and atypical treatment approach including salvage irradiation and mon…
Imaging of urinary bladder hernias
2005
Lorenzo E. Bacigalupo1, Michele Bertolotto2, Filippo Barbiera3, Pietro Pavlica4, Roberto Lagalla3, Roberto S. Pozzi Mucelli2, Lorenzo E. Derchi1 Bacigalupo LE, Bertolotte M, Barbiera F, et al. erniation of the urinary bladder is not rare. It is usually considered that 1–3% of all inguinal hernias involve the bladder [1], and Iason [2], in 1944, reported an incidence of 10% in men older than 50 years. Most bladder hernias involve the inguinal and femoral canals, with the latter more frequent in women, and a predilection for the right side has been reported. However, herniations through ischiorectal, obturator, and abdominal wall openings have also been described. Any portion of the bladder m…
Cells expressing markers of immature neurons in the amygdala of adult humans
2012
The polysialylated form of the neuronal cell adhesion molecule (PSA-NCAM) is expressed by immature neurons in the amygdala of adult mammals, including non-human primates. In a recent report we have also described the presence of PSA-NCAM-expressing cells in the amygdala of adult humans. Although many of these cells have been classified as mature interneurons, some of them lacked mature neuronal markers, suggesting the presence of immature neurons. We have studied, using immunohistochemistry, the existence and distribution of these immature neurons using post mortem material. We have also analysed the presence of proliferating cells and the association between immature neurons and specialise…
Long-term hydrocephalus alters the cytoarchitecture of the adult subventricular zone
2014
Hydrocephalus can develop secondarily to a disturbance in production, flow and/or absorption of cerebrospinal fluid. Experimental models of hydrocephalus, especially subacute and chronic hydrocephalus, are few and limited, and the effects of hydrocephalus on the subventricular zone are unclear. The aim of this study was to analyze the effects of long-term obstructive hydrocephalus on the subventricular zone, which is the neurogenic niche lining the lateral ventricles. We developed a new method to induce hydrocephalus by obstructing the aqueduct of Sylvius in the mouse brain, thus simulating aqueductal stenosis in humans. In 120-day-old rodents (n = 18 per group), the degree of ventricular d…
