Delivery of epirubicin via slow infusion as a strategy to mitigate chemotherapy-induced cardiotoxicity
2017
Background Continuous infusion of doxorubicin has been a strategy to reduce cardiotoxicity. Epirubicin is another anthracycline in common clinical use. However, evidence is lacking regarding whether this strategy can reduce cardiotoxicity of epirubicin without compromising antineoplastic efficacy. Design and methods Healthy rats were randomized into groups: epirubicin (8 mg/kg) delivered intraperitoneally via micro osmotic pumps (MOP), epirubicin (8 mg/kg) by intraperitoneal (IP) bolus injection, and placebo control. Blood samples were collected for analyzing biomarkers of myocardial injury and pharmacokinetics. At chosen times, sub-groups of animals were sacrificed for histopathology. A mo…
Prolonged Cerebral Circulation Time Is the Best Parameter for Predicting Vasospasm during Initial CT Perfusion in Subarachnoid Hemorrhagic Patients
2016
Purpose We sought to imitate angiographic cerebral circulation time (CCT) and create a similar index from baseline CT perfusion (CTP) to better predict vasospasm in patients with subarachnoid hemorrhage (SAH). Methods Forty-one SAH patients with available DSA and CTP were retrospectively included. The vasospasm group was comprised of patients with deterioration in conscious functioning and newly developed luminal narrowing; remaining cases were classified as the control group. The angiography CCT (XA-CCT) was defined as the difference in TTP (time to peak) between the selected arterial ROIs and the superior sagittal sinus (SSS). Four arterial ROIs were selected to generate four correspondin…
The use of opioids in the last week of life in an acute palliative care unit.
2010
The aim of this survey was to assess the opioid use in the last week of life of cancer patients admitted at an acute palliative care unit. From a consecutive sample of patients surveyed for a period of one year, patients who died in the unit were selected. Type of opioid, route of administration, and doses were recorded one week before death (or at admission time if the interval admission-death was less than one week) (-7), and on the day of death (Tend). Seventy-seven patients died in the unit in the period taken into consideration (12.4%). Oral morphine equivalents were 170 mg/day and 262 mg/day at -7 and Tend, respectively. Patients were receiving transdermal drugs or intravenous morphi…
The rewarding effects of ethanol are modulated by binge eating of a high-fat diet during adolescence
2017
Abstract Binge-eating is considered a specific form of overeating characterized by intermittent and high caloric food intake in a short period of time. Epidemiologic studies support a positive relation between the ingestion of fat and ethanol (EtOH), specifically among adolescent subjects. The aim of this work was to clarify the role of the compulsive, limited and intermittent intake of a high-fat food during adolescence on the rewarding effects of EtOH. After binge-eating for 2 h, three days a week from postnatal day (PND) 29, the reinforcing effects of EtOH were tested with EtOH self-administration (SA), conditioned place preference (CPP) and ethanol locomotor sensitization procedures in …
The oral KIF11 inhibitor 4SC‐205 exhibits antitumor activity and potentiates standard and targeted therapies in primary and metastatic neuroblastoma …
2021
Inhibidor de KIF11; Terapias dirigidas; Metástasis Inhibidor de KIF11; Teràpies dirigides; Metàstasi KIF11 inhibitor; Targeted therapies; Metastasis In summary, our study provides a rationale for the future therapeutic integration in clinical trials of 4SC-205, an structurally distinct oral KIF11 inhibitor that shows potent antitumor activity in multiple preclinical neuroblastoma models and sensitizes neuroblastoma cells to standard chemotherapy and specific neuroblastoma-targeted therapies. The financial support for this research was provided by Instituto de Salud Calos III (PI20/00530 to Miguel F. Segura; PI20/01107 to Rosa Noguera; PI17/02248 and CPII18/00027 to Anna Santamaria; PI19/013…
Cycling for Home-to-School Travel in Palermo: A Method for Assessing the Optimal Allocation of New Cycling Infrastructure
2019
In order to reduce the number of cars on the road, one of the most incisive actions is to encourage cycling, e.g. through the introduction of bike-sharing systems. In particular, the activation of special bike-sharing programs for school students could lead students to choose this mode of transport to make their own home-school travel. The success of such initiatives is primarily linked to the presence of a continuous and functional cycle network, which can create safe routes to school. It is, therefore, necessary a cycle network design model that allows determining the optimal allocation of new cycle paths, maximizing the number of users and considering technical and economic constraints. …
Release of naltrexone on buccal mucosa: Permeation studies, histological aspects and matrix system design
2007
Transbuccal drug delivery has got several well-known advantages especially with respect to peroral way. Since a major limitation in buccal drug delivery could be the low permeability of the epithelium, the aptitude of NLX to penetrate the mucosal barrier was assessed. Ex vivo permeation across porcine buccal mucosa 800 microm thick was investigated using Franz type diffusion cells and compared with in vitro data previously obtained by reconstituted human oral epithelium 100 microm thick. Both fluxes (Js) and permeability coefficients (K(p)) are in accordance, using either buffer solution simulating saliva or natural human saliva. Permeation was evaluated also in presence of chemical enhance…
Paesaggio e relazioni contestuali per la persistenza della memoria: l’itinerario APER
2017
Le relazioni contestuali del patrimonio architettonico costituiscono un elemento imprescindibile per comprenderlo, conservarlo e valorizzarlo, adottando un approccio che accolga la complessità delle sue dimensioni. Nel paesaggio contemporaneo persistono le tracce del passato in forme diversamente percepibili, ma spesso ne manca la consapevolezza: restituire leggibilità al sistema di relazioni tra elementi puntuali e tessuto connettivo è uno degli obiettivi della valorizzazione del patrimonio che può essere perseguito tramite lo strumento degli itinerari tematici. Dopo un inquadramento generale del tema, il contributo illustra una proposta d’itinerario che ripercorre l’antica via Selinuntina…
Evidence of a flip-flop phenomenon in acamprosate pharmacokinetics: an in vivo study in rats.
2006
The pharmacokinetics of acamprosate were examined in the rat after oral and intravenous administration in order to detect the possible presence of a flip-flop phenomenon. Rats received 9.3 or 73.3 mg/kg of the drug as an intravenous bolus. The same doses were orally administered via gastric intubation. Plasma samples were taken from the jugular vein for determination of acamprosate concentration by liquid scintillation counting. The drug content was also quantified in urine and faeces. The acamprosate bioavailability was close to 20%, the amount recovered in the faeces being around 80% of the administered dose. The terminal slope of the oral plasma curve was significantly lower than that ob…
