Methodological Approach to Use Fresh and Cryopreserved Vessels as Tools to Analyze Pharmacological Modulation of the Angiogenic Growth
2016
The sprouting of new vessels is greatly influenced by the procedure chosen. We sought to optimize the experimental conditions of the angiogenic growth of fresh and cryopreserved vessels cultured in Matrigel with the aim to use this system to analyze the pharmacological modulation of the process. Segments of second-order branches of rat mesenteric resistance arteries, thoracic aorta of rat or mouse, and cryopreserved rat aorta and human femoral arteries were cultured in Matrigel for 7-21 days in different mediums, as well as in the absence of endothelial or adventitia layer. Quantification of the angiogenic growth was performed by either direct measurement of the mean length of the neovessel…

Real-life use of elbasvir/grazoprevir in adults and elderly patients: a prospective evaluation of comedications used in the PITER cohort.
2021
Background In patients treated for HCV infection, potential drug–drug interactions (DDIs) can occur among direct-acting antiviral drugs (DAAs) and comedications used. The real-life effectiveness and safety of elbasvir/grazoprevir (ELB/GZR) among co-medicated HCV patients was evaluated. Methods We prospectively evaluated consecutive patients from 15 clinical centres participating in PITER who were treated with ELB/GZR and had been followed for at least 12 weeks after treatment. Data were prospectively collected on the use of comedications (including discontinuation, dose modification and addition of drugs) and potential DDIs with DAAs. Results Of the 356 patients with at least 12-week post-t…
In the rat maximal dentate activation model of partial complex epilepsy, the anticonvulsant activity of levetiracetam is modulated by nitric oxide-ac…
2009
The effects of nitric oxide-active drugs on the anticonvulsant action of the antiepileptic drug levetiracetam in an experimental model of partial complex seizures named maximal dentate gyrus activation were studied in rats. Levetiracetam was given alone or in combination with 7-nitroindazole, a preferential inhibitor of neuronal nitric oxide synthase, or with L: -arginine, the precursor of nitric oxide synthesis. The maximal dentate activation parameters were the time of latency and the durations of maximal dentate activation and afterdischarge responses. The administration of levetiracetam showed an anticonvulsant effect that was increased when given in combination with 7-nitroindazole. Th…
Outcome of urgent and elective percutaneous coronary interventions after pharmacologic reperfusion with tenecteplase combined with unfractionated hep…
2003
Item does not contain fulltext OBJECTIVES: The aim of this study was to evaluate percutaneous coronary intervention (PCI) in the Assessment of the Safety and Efficacy of New Thrombolytic Regimens (ASSENT-3) trial. BACKGROUND: In the ASSENT-3 trial, co-therapy with abciximab (ABC) or enoxaparin (ENOX) reduced ischemic complications after ST-elevation acute myocardial infarction treated with tenecteplase when compared with unfractionated heparin (UFH). The effect of these new co-therapies on the results of PCI is unknown. METHODS: Clinical outcomes in patients who received co-therapy with ABC, ENOX, or UFH and subsequently underwent an elective (n = 1,064) or urgent (n = 716) PCI in the ASSEN…
Non-vitamin K antagonist oral anticoagulants in the treatment of coronary and peripheral atherosclerosis
2019
Oral anticoagulants (OACs) are widely used for prevention of systemic thromboembolism, including the reduction of the risk of stroke in patients with atrial fibrillation (AF) and prosthetic heart valves. There is also an increasing population of patients who require not only OACs, but also double antiplatelet therapy (DAPT). A typical example is a patient with AF and stable coronary artery disease or acute coronary syndrome (ACS), treated by percutaneous coronary intervention. In recent years, with the introduction of NOACs, triple or dual therapy has become safer. Regardless of these indications for the use of NOACs, rivaroxaban at a reduced dose has proved to efficiently reduce the risk o…
Combination Therapy with Oral Treprostinil for Pulmonary Arterial Hypertension:A Double-Blind Placebo-controlled Clinical Trial
2020
Rationale: Oral treprostinil improves exercise capacity in patients with pulmonary arterial hypertension (PAH), but the effect on clinical outcomes was unknown.\ud \ud Objectives: To evaluate the effect of oral treprostinil compared with placebo on time to first adjudicated clinical worsening event in participants with PAH who recently began approved oral monotherapy.\ud \ud Methods: In this event-driven, double-blind study, we randomly allocated 690 participants (1:1 ratio) with PAH to receive placebo or oral treprostinil extended-release tablets three times daily. Eligible participants were using approved oral monotherapy for over 30 days before randomization and had a 6-minute-walk dista…
Effectiveness and safety of glecaprevir/pibrentasvir in chronic hepatitis C patients: Results of the Italian cohort of a post-marketing observational…
2021
Abstract Background and Aims The MARS post-marketing, observational study evaluates glecaprevir/pibrentasvir in a large population of Italian patients who are infected with HCV. Patients and Methods Achievement of SVR12 was the primary endpoint in the overall population and by subpopulations of interest (treatment-naive and treatment-experienced patients, subjects infected with different HCV genotype/sub-genotype, cirrhotic and non-cirrhotic patients, patients with different severity of fibrosis, patients with an APRI score ≥1, subjects with comorbidities, HIV-coinfected patients, elderly patients and people who use drugs). Safety and quality of life (assessed by SF-36 and Work Productivity…
Behavioral Effects of GABAA Receptor Stimulation and GABA-Transporter Inhibition
2000
Abstract The present analysis addressed behavioral changes after treatment with 4.5 mg/kg or 18.5 mg/kg of the GABA-uptake inhibitor tiagabine combined with either the benzodiazepine diazepam (1.5 mg/kg) or the imidazopyridine zolpidem (0.05 mg/kg), the latter two acting differentially on GABA A receptor subtypes. The study included 97 male PVG/OIaHsd rats. A standard open field, an enriched open field, and an elevated plus-maze was used to study rat behavior. Treatment with the low dose of tiagabine alone induced no specific behavioral effects, whereas the high dose had an anxiolytic-like potential. Furthermore, diazepam but not zolpidem displayed anxiolytic-like effects. Combination of ea…
Incidence and risk factors of post-engraftment invasive fungal disease in adult allogeneic hematopoietic stem cell transplant recipients receiving or…
2015
Studies that analyze the epidemiology and risk factors for invasive fungal disease (IFD) after engraftment in alloSCT are few in number. This single-center retrospective study included 404 alloSCT adult recipients surviving > 40 days who engrafted and were discharged without prior IFD. All patients who received >= 20 mg/day of prednisone were assigned to primary oral prophylaxis (itraconazole or low-dose voriconazole). The primary end point was the cumulative incidence (CI) of probable/proven IFD using the European Organization for Research and Treatment of Cancer and Mycoses Study Group (EORTC/MSG) criteria. The independent prognostic factors after multivariate analyses were used to constr…
