Difficulties In Emotion Regulation During Rehabilitation For Alcohol Addiction: Correlations With Metacognitive Beliefs About Alcohol Use And Relapse Risk.

PURPOSE: Understanding how difficulties in emotion regulation can be related to metacognitive beliefs during early abstinence, identifying which factors are associated with craving and relapse risk may be useful in residential rehabilitation treatment of alcohol addiction. METHODS: Sixty-five patients underwent a 28-day rehabilitation program for alcohol addiction. They underwent a brief semi-structured interview at admission and completed a battery of five self-report questionnaires between days 7 and 10 of alcohol abstinence (T0) and 3 days prior to discharge (T1). RESULTS: After rehabilitation program, all symptoms of psychological distress decreased. We found a significant improvement in all emotional, cognitive and metacognitive scales except for "Cognitive harm" (NAM), "Awareness" (DERS) and a small effect size (low statistical power) for "Emotional clarity" (DERS). Compared to those still abstinent at 1 month from discharge, we found more difficulties in "Emotional clarity" in those who had an early relapse. Difficulties in "Emotional clarity" were observed also in patients with a high level of craving at discharge. CONCLUSION: Significant differences were observed between the groups "abstinence vs non-abstinence" at 1 month from discharge concerning difficulties in emotion regulation. In particular, we found difficulty in the awareness and understanding of emotion, precisely to identify correctly the emotions. The "Emotional Clarity" seems to be the emotional difficulty that characterized also the group with a high level of craving at discharge and the individuals with early relapse, suggesting the importance of this function as a preliminary factor in emotion regulation.

Polyphenol pattern and antioxidant activity of different tomato lines and cultivars.

BACKGROUND/AIMS: Besides antioxidant vitamins and minerals, fruits and vegetables contain flavonoids and related phenolics. The biological activities of these polyphenols have become well known in recent years evidencing their beneficial effects on human health. In this context, the characterization of the flavonoids present in tomatoes is of great interest. Thus the polyphenol pattern (including flavonols, flavanones and cinnamate derivatives), lycopene and beta-carotene concentrations and the total antioxidant activity (TAA) of the phenolic fraction from different tomato lines and cultivars have been determined. METHODS: The characterization was obtained by means of spectrophotometry and HPLC analyses. RESULTS: Mean values for single flavonoids were 0.68 +/- 0.16 for naringenin, 0.74 +/- 0.12 for rutin and 0.32 +/- 0.06 for a rutin-pentoside. Mean total polyphenol content was 13.15 +/- 1.15 mg/100 g and mean TAA value was 1.3 +/- 0.10 mmol/g. The obtained TAA values resulted in good accordance with the total polyphenol content (R(2) = 0.7928). The main phenolic acids were chlorogenic (mean +/- SE 0.20 +/- 0.03) and caffeic acid (mean +/- SE 0.03 +/- 0.01). Mean levels of lycopene and beta-carotene were 5.38 +/- 0.90 and 1.18 +/- 0.40 mg/100 g, respectively. CONCLUSIONS: Almost all the lines characterised by low carotenoid content produce high levels of polyphenols, and consequently have the most powerful antioxidant potential.

Simultaneous detection of cucumber mosaic virus, tomato mosaic virus and potato virus Y by flow cytometry.

The simultaneous detection is described of cucumber mosaic virus (CMV), potato virus Y (PVY) and tomato mosaic virus (ToMV) by flow cytometry. Extracts from leaves of healthy and CMV or PVY infected plants were incubated with latex particles, each with a diameter of 3 microm. Extracts from ToMV infected or uninfected plants, however, were incubated with particles, each with a diameter of 6 microm. Beads were washed and incubated in succession with primary and secondary antibodies, the latter labeled with phycoerythrin (PE) or fluorescein (FITC). CMV and PVY were distinguished on the basis of the fluorescence emitted by FITC and PE; ToMV was distinguished from CMV and PVY on the basis of the different diameter (6 microm) of the particles on which it was adsorbed. The three viruses were detected also by another approach. Latex particles with a diameter of 3, 6 and 10 microm were separately sensitized with antibodies specific for CMV, PVY and ToMV. An equal number of sensitized particles was mixed and incubated with the plant extracts containing the three viruses and then with anti-CMV, anti-PVY and anti-ToMV antibodies labeled with FITC. The study describes also a virus purification method based on the use of antibody coated latex particles. The method is simple technically and applicable to the purification of large as well as minute amounts of different viruses (CMV, PVY and ToMV).
