Pre-clinical assessment of a water-in-fluorocarbon emulsion for the treatment of pulmonary vascular diseases

2019

Abstract Hypoxic pulmonary vasoconstriction (HPV) is a well-characterized vascular response to low oxygen pressures and is involved in life-threatening conditions such as high-altitude pulmonary edema (HAPE) and pulmonary arterial hypertension (PAH). While the efficacy of oral therapies can be affected by drug metabolism, or dose-limiting systemic toxicity, inhaled treatment via pressured metered dose inhalers (pMDI) may be an effective, nontoxic, practical alternative. We hypothesized that a stable water-in-perfluorooctyl bromide (PFOB) emulsion that provides solubility in common pMDI propellants, engineered for intrapulmonary delivery of pulmonary vasodilators, reverses HPV during acute h…

In vivo antigenotoxic effects of dietary allyl sulfides in the rat

1997

The effects of dietary administration of diallyl sulfide (DAS), diallyl disulfide (DADS) and allyl mercaptan (AM) on the genotoxicity of different chemicals were studied in two experimental systems: (i) measurement of hepatic DNA single-strand breaks induced in rats by aflatoxin B1 (AFB1), N-nitrosodimethylamine (NDMA) or methylnitrosourea (MNU); (ii) mutagenicity of AFB1 or NDMA on Salmonella typhimurium TA100 using hepatic S9 from rats fed allyl sulfides as the activation system. All compounds strongly reduced hepatic DNA breaks induced by AFB1 and NDMA but did not modify the genotoxicity of MNU. In the Ames test, the mutagenicity of NDMA was strongly inhibited by hepatic S9 from rats fed…

School in Italy: a safe place for children and adolescents

2021

AbstractBackgroundDuring the first SARS-CoV-2 pandemic phase, the sudden closure of schools was one of the main measures to minimize the spread of the virus. In the second phase, several safety procedures were implemented to avoid school closure.To evaluate if the school is a safe place, students and staff of two school complexes of Rome were monitored to evaluate the efficacy of prevention measures inside the school buildings.MethodsOral secretions specimens were collected from 1262 subjects for a total of 3431 samples, collected over a 3 months period.Detection of Coronavirus SARS-CoV-2 was performed by real-time PCR. Target genes were represented by E gene, RdRP/S gene and N gene.Results…

The GENDER ATTENTION Observational Study: Gender and Hormonal Status Differences in the Incidence of Adverse Events During Cyclosporine Treatment in …

2017

Introduction: Female sex has been shown to be a risk factor for the development of adverse drug reactions; however, this has not been studied for cyclosporine (CsA). The aim of this study was to investigate, in Italian dermatological practice, the influence of gender and menopause and related hormones on the incidence of adverse events (AEs) during CsA treatment in psoriatic patients. Methods: Multicenter, prospective, observational study conducted from May 2011 to June 2013. Patients with plaque psoriasis, undergoing a new CsA administration course, or about to start it, were enrolled in the outpatient clinics of Italian dermatological centers. During the 2–6 months of study duration, pati…

Controlled Iontophoretic Delivery in Vitro and in Vivo of ARN14140—A Multitarget Compound for Alzheimer’s Disease

2019

ARN14140 is a galantamine-memantine conjugate that acts upon both cholinergic and glutamatergic pathways for better management of Alzheimer's disease. Poor oral bioavailability and pharmacokinetics meant that earlier preclinical in vivo studies employed intracerebroventricular injection to administer ARN14140 directly to the brain. The aim of the present study was to evaluate the feasibility of using constant current transdermal iontophoresis for the noninvasive systemic delivery of ARN14140 and to quantify the amounts present in the blood and the brain. Preliminary experiments in vitro were performed using porcine skin and validated with human skin. Cumulative ARN14140 permeation across th…

The protective role ofOcimum basilicumL. (Basil) against aspirin-induced gastric ulcer in mice: Impact on oxidative stress, inflammation, motor defic…

2018

The gastroprotective effect of Ocimum basilicum L. (Basil) hexane extract (OBHE) in aspirin-induced gastric ulcers in mice and its ameliorative effect on behavioral alterations were determined. Pretreatment with OBHE (100 or 200 mg kg-1) or misoprostol (50 μg kg-1) alleviated the aspirin-induced oxidative stress by significantly decreasing (p < 0.001) gastric ulcer index scores (57, 76 and 79%), gastric TBARS (by 49, 51 and 52%), NO (21, 28 and 29%), H2O2 (24, 42 and 45%), and the serum pro-inflammatory mediator TNF-α (21, 53 and 53%) and IL-6 (29, 30 and 31%), as well as by markedly increasing gastric GSH (41, 61 and 70%), GSH-Px (21, 32 and 34%), GST (33, 63 and 70%), GR (90, 99 and 112%)…

Comparison of segmental-dependent permeability in human and in situ perfusion model in rat.

2017

Abstract Nowadays, alternative methods have been developed to predict intestinal permeability values in human as in vitro, in situ or ex vivo methods. They were developed by the necessity to avoid the problems of the human permeability experiments. However, determination of human permeability is needed to properly validate the alternative methods. For this reason, recently, Dahlgren et al. published an indirect method based on a deconvolution technique to estimate the human permeability in different gastrointestinal segments (jejunum, ileum and colon). Therefore, the objective of this research was to demonstrate that Doluisio technique is a useful method to predict the human permeability in…

Impact of Pharmacists’ Participation in a Pharmacotherapy Follow-Up Program

2012

Objective. To evaluate the impact of a continuing pharmacy education (CPE) course on Spanish community pharmacists’ participation in a pharmacotherapy follow-up program. Design. Participation in a CPE course offered 4 times over a 4-year period via satellite teleconferencing was monitored and the data analyzed to determine the course’s impact on community pharmacists’ participation in a pharmacotherapy follow-up program. Assessment. Community pharmacists’ participation in the pharmaceutical care CPE course had a slightly positive impact on their participation in the pharmacotherapy follow-up program. In the best profiles, there was a probability of 7.3% that participants would participate i…

Early Sacubitril/Valsartan-driven Benefit on Exercise Capacity in Heart Failure With Reduced Ejection Fraction: A Pilot Study

2017

Model‐based meta‐analysis of the time to first acute urinary retention or benign prostatic hyperplasia‐related surgery in patients with moderate or s…

2021

Aims Combination therapy of 5α‐reductase inhibitor and α‐blocker is a guideline‐endorsed therapeutic approach for patients with moderate‐to‐severe lower urinary tract symptoms or benign prostatic hyperplasia (LUTS/BPH) who are at risk of disease progression. We aimed to disentangle the contribution of clinical and demographic baseline characteristics affecting the risk of acute urinary retention or BPH‐related surgery (AUR/S) from the effect of treatment with drugs showing symptomatic and disease‐modifying properties. Methods A time‐to‐event model was developed using pooled data from patients (n = 10 238) enrolled into six clinical studies receiving placebo, tamsulosin, dutasteride or tamsu…
