Chemotherapy-induced cardiotoxicity: role of the conventional echocardiography and the tissue Doppler.

2011

Aim. The cardiotoxicity of anticancer drugs is an emerging problem and only an identification of the early signs of cardiotoxicity by conventional echocardiography and not (tissue Doppler imaging, TDI), will limit and contain the long-term cardiotoxicity effects. The aim of this study was to identify, through conventional echocardiography and TDI, parameters to use as early "signs" of cardiotoxicity. Methods. A prospective study was performed using patients with breast cancer (72 women, median age 57+/-12) treated with anticancer drugs (adjuvant chemotherapy). All patients underwent a careful cardiological evaluation before starting treatment (T0) and during follow-up at 3 months (T1), 6 mo…

HISTONE DEACETYLASE (HDAC) INHIBITION MODULATES INTRACELLULAR DEOXYNUCLEOTIDES (DNTP) POOLS AND POTENTIATES THE ANTITUMOR EFFECTS OF THE RIBONUCLEOTI…

2009

HDAC inhibitors are a new class of antitumor agents that were reported to enhance the cytotoxic effects of a number of classical anticancer drugs through multiple mechanisms. In particular, they are capable of modulating the expression of a series of key cellular genes leading to significant antiproliferative and apoptotic effects. However, which of the possible drug combinations would be the most effective and clinically useful is still to be determined. We treated the HL60 and NB4 promyelocitic leukaemia cells with a combination of the RR inhibitor 3’-Me-Ado and several hydroxamic acid–derived HDAC inhibitors, including the two recently synthesized molecules, MC1864 and MC1879, and the re…

Natural Inhibitors of P-glycoprotein in AcuteMyeloid Leukemia

2023

Acute myeloid leukemia (AML) remains an insidious neoplasm due to the percentage of patients who develop resistance to both classic chemotherapy and emerging drugs. Multidrug resistance (MDR) is a complex process determined by multiple mechanisms, and it is often caused by the overexpression of efflux pumps, the most important of which is P-glycoprotein (P-gp). This mini-review aims to examine the advantages of using natural substances as P-gp inhibitors, focusing on four molecules: phytol, curcumin, lupeol, and heptacosane, and their mechanism of action in AML.

Analisi statistica dei casi di intossicazione rilevati al pronto soccorso dell’Ospedale Sant’Antonio Abate di Trapani nel periodo 2010-2014

2015

Premesse e Scopo dello studio: Lo studio ha lo scopo di analizzare i casi di intossicazione presso il P.O. Sant’Antonio Abate di Trapani con l’obiettivo di stimare e identificare l’incidenza delle intossicazioni afferenti al Pronto Soccorso. Materiali e Metodi: Sono stati raccolti dati individuali in un campione di 1220 soggetti, che presentavano un quadro sintomatologico da riferire in tutto o in parte all’intossicazione. Sono stati inclusi nello studio i casi da prodotti industriali, veleni per animali, antiparassitari, gas e vapori tossici, prodotti domestici, cosmetici, farmaci, prodotti chimici non farmaceutici, droghe e alcool, veleni animali e vegetali. Risultati: I maschi sono 810 (…

Formulation of liposomes loading lentisk oil to ameliorate topical delivery, attenuate oxidative stress damage and improve cell migration in scratch …

2021

[EN] Pistacia lentiscus L. is a sclerophyllous shrub capable of growing under harsh climatic conditions especially in the Mediterranean Basin. Different products can be obtained from this plant, such as essential oil, mastic gum or even fixed oil. The last is well known for its flavor which is mainly exploited in the food industry. Additionally, it has been traditionally used in the treatment of skin diseases, but, at the moment, any suitable formulation for skin delivery has been formulated and its biological effects was not deeply confirmed. Given that, in the present study, the lentisk oil has been formulated in liposomes at different concentrations (10, 20, 30 mg/ml) and their physicoch…

Ketoprofen photodermatosis

2013

Background and aim of the study: The aim of the following review is that of stimulating and highlighting the importance of pharmacovigilance, examining all the data about ketaprofen (a well known NSAD) photodermatosis cases reported in literature, especially those occurred in patients under topical therapy that have been revealed to be adverse reactions. Materials and methods: Analysed data concern studies carried out from 1991 to 2011 among different European countries, in particular at the Swedish University of Lund, Katholieke University of Leuven in Belgium, and in France. All the data arrived through the Italian national pharmacovigilance network. Results: Evidences show that the basic…

Essential oil of Cyphostemma juttae (Vitaceae): Chemical composition and antitumor mechanism in triple negative breast cancer cells

2019

The genus Cyphostemma (Planch.) Alston (Vitaceae) includes about 150 species distrib- uted in eastern and southern Africa and Madagascar. Some species are used in traditional medicine and their biological activities, including antiproliferative effects against cancer cell lines, have been demonstrated. To date no investigations on Cyphostemma essential oils have been carried out. Essential oils, which play important roles in plant defenses have been demonstrated to be active in the treatment of several human diseases and to enhance bioavability of other drugs. The aim of this paper was to identify the chemical composition of the essential oil of the leaves of Cyphostemma juttae (Dinter &amp…
