Metabolomics and antioxidant activity of the leaves of Prunus dulcis Mill. (Italian cvs. Toritto and Avola)

Publication date: 5 September 2018Source: Journal of Pharmaceutical and Biomedical Analysis, Volume 158Author(s): Alfredo Bottone, Paola Montoro, Milena Masullo, Cosimo Pizza, Sonia PiacenteAbstractPrunus dulcis leaves have been reported to exert some biological activity, in particular potent free radical-scavenging capacity, but so far there is limited information on their chemical composition. With the aim to achieve deep insight on the chemical constituents of the leaves of P. dulcis cultivars “Toritto” and “Avola”, the most appreciated in Italy, an approach based on liquid chromatography-mass spectrometry (LC–MS) combined with isolation and structure elucidation of pure compounds by Nuclear Magnetic Resonance (NMR) analysis was carried out. Results allowed to detect in cv. Toritto leaves phenolics, terpenoids and a cyanogenic glycoside. Successively, various solvent systems were chosen to afford different extracts and an approach based on principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) from LC–MS data sets highlighted eco-friendly methods as selective in extracting phenolics and glycosides. Comparison of LC–MS profiles of the MeOH extracts of cv. Toritto and cvs. Avola (Pizzuta, Fascionello and Romana) leaves and evaluation of their phenolic contents and antioxidant activity were also carried out.Graphical abstract

This study aimed to understand family communication and overall well-being of young adults in the context of familial opioid misuse using the family systems framework. Methods: A cross-sectional, mixed-methods, online survey of young adults aged 18 to 30 years (n=137) was conducted. A cluster analysis was performed based on family organization and structural characteristics. MANCOVA was utilized to compare groups identified using the cluster analysis in terms of (1) family’s belief about opioid misuse, (2) worry regarding opioid misuse, (3) family communication, and (4) overall well-being of young adults. Results...

Background and Aim: Controlling the symptoms of opioid withdrawal syndrome is important for the treatment of opioid addiction. There is very limited evidence on the effectiveness of pregabalin on opioid withdrawal syndrome. The present study examines the effectiveness of pregabalin in reducing opioid withdrawal symptoms. Methods: This double-blind clinical-trial was conducted on noninjecting opioid users diagnosed with opioid dependence and referred to the Addiction Treatment Center of Khorshid Hospital in Isfahan, Iran, in 2015 and 2016. The patients were divided into intervention and control groups, and both groups ...

This article reports an integrative review of seven trials carried out from 2007 to 2016, investigating the use of TMS on subjects abusing cocaine. The analysis was categorized into 5 different topics (1) area of intervention; (2) hemisphere; (3) number of pulses and intensity; (4) safety and adverse effects; and (5) other outcomes. Most of the trials found promising results of craving and/or use reduction with repetitive TMS (rTMS). Future interventions should consider the use of TMS as part of rehabilitation therapies.

Conclusions: These findings show that in Brazil problems related to alcohol use by the elderly remain relatively unknown. There was a high heterogeneity of methodologies in the studies, making it difficult to summarize the findings and produce prevalence estimates for the different patterns of consumption. More homogenous studies using similar definitions of patterns of alcohol consumption are required to allow comparisons to be made between different Brazilian regions and other countries.

Conclusions: A change was detected in the profile of treatment-seeking crack cocaine users over the past 2 decades. Current patients appear to be older and use the drug more chronically, in addition to having a higher level of schooling and lower unemployment rates when compared with 1997 users.

Objectives: For patients with opioid addiction seeking treatment, an effective option is Medication-assisted Treatment (MAT). In Albuquerque, the city with the greatest number of people who use opioids in New Mexico, the demand for MAT exceeds the number of patients receiving treatment. The authors hypothesized that a primary factor in patients’ ability to access treatment is clinic payment options, rather than the traditionally cited availability of providers. Methods: The authors conducted a survey assessing payment methods and corresponding availability in MAT programs for 53 of Albuquerque’s ~70 provid...
