Pro-environmental behaviors: Determinants and obstacles among italian university students
none31The awareness of citizens concerning the health risks caused by environmental pollution is growing, but studies on determinants of pro-environmental behaviors have rarely examined health-related aspects. In this study, we investigated these determinants using data from a large survey among Italian university students (15 Universities: 4778 filled questionnaires). Besides the health-related aspects, represented by environmental health risk perception and functional health literacy, we considered social and demographic characteristics (gender, area of residence, sources of information, trust in institutional and non-institutional subjects, and students’ capacity of positive actions, indicated as internal locus of control). The attitudes towards pro-environmental behaviors were positive for more than 70% of students and positively related with health risk perception, internal locus of control, and health literacy. The correspondence between the positive attitudes towards pro-environmental behaviors and the real adoption of such behaviors was approximately 20% for most behaviors, except for the separate collection of waste (60%). Such a discrepancy can be attributable to external obstacles (i.e., lack of time, costs, lack of support). The health-related aspects were linked to the pro-environmental attitudes, but to a lesser extent to pro-environmental behaviors, owing to the complexity of their determinants. However, they should be taken in account in planning education interventions.openCarducci A.; Fiore M.; Azara A.; Bonaccorsi G.; Bortoletto M.; Caggiano G.; Calamusa A.; De Donno A.; De Giglio O.; Dettori M.; Di Giovanni P.; Di Pietro A.; Facciola A.; Federigi I.; Grappasonni I.; Izzotti A.; Libralato G.; Lorini C.; Montagna M.T.; Nicolosi L.K.; Paladino G.; Palomba G.; Petrelli F.; Schiliro T.; Scuri S.; Serio F.; Tesauro M.; Verani M.; Vinceti M.; Violi F.; Ferrante M.Carducci, A.; Fiore, M.; Azara, A.; Bonaccorsi, G.; Bortoletto, M.; Caggiano, G.; Calamusa, A.; De Donno, A.; De Giglio, O.; Dettori, M.; Di Giovanni, P.; Di Pietro, A.; Facciola, A.; Federigi, I.; Grappasonni, I.; Izzotti, A.; Libralato, G.; Lorini, C.; Montagna, M.

Wild vascular plants gathered for consumption in the Polish countryside: a review
BACKGROUND: This paper is an ethnobotanical review of wild edible plants gathered for consumption from the end of the 18(th )century to the present day, within the present borders of Poland. METHODS: 42 ethnographic and botanical sources documenting the culinary use of wild plants were analyzed. RESULTS: The use of 112 species (3.7% of the flora) has been recorded. Only half of them have been used since the 1960s. Three species: Cirsium rivulare, Euphorbia peplus and Scirpus sylvaticus have never before been reported as edible by ethnobotanical literature. The list of wild edible plants which are still commonly gathered includes only two green vegetables (Rumex acetosa leaves for soups and Oxalis acetosella as children's snack), 15 folk species of fruits and seeds (Crataegus spp., Corylus avellana, Fagus sylvatica, Fragaria vesca, Malus domestica, Prunus spinosa, Pyrus spp., Rosa canina, Rubus idaeus, Rubus sect. Rubus, Sambucus nigra, Vaccinium myrtillus, V. oxycoccos, V. uliginosum, V. vitis-idaea) and four taxa used for seasoning or as preservatives (Armoracia rusticana root and leaves, Carum carvi seeds, Juniperus communis pseudo-fruits and Quercus spp. leaves). The use of other species is either forgotten or very rare. In the past, several species were used for food in times of scarcity, most commonly Chenopodium album, Urtica dioica, U. urens, Elymus repens, Oxalis acetosella and Cirsium spp., but now the use of wild plants is mainly restricted to raw consumption or making juices, jams, wines and other preserves. The history of the gradual disappearance of the original barszcz, Heracleum sphondylium soup, from Polish cuisine has been researched in detail and two, previously unpublished, instances of its use in the 20(th )century have been found in the Carpathians. An increase in the culinary use of some wild plants due to media publications can be observed. CONCLUSION: Poland can be characterized as a country where the traditions of culinary use of wild plants became impoverished very early, compared to some parts of southern Europe. The present use of wild plants, even among the oldest generation, has been almost entirely restricted to fruits
Small effects of valproic acid on the plasma concentrations of clozapine and its major metabolites in patients with schizophrenic or affective disorders
Two separate studies were carried out to assess the effect of valproic acid on the steady-state plasma concentrations of clozapine and its major metabolites norclozapine and clozapine N-oxide in psychotic patients. In the first study, concentrations of clozapine and metabolites were compared between patients treated with clozapine in combination with sodium valproate (n = 15) and control patients treated with clozapine alone (n = 22) and matched for sex, age, body weight, and antipsychotic dosage. Patients comedicated with valproate tended to have higher clozapine levels and lower norclozapine levels, but the differences did not reach statistical significance. In a subsequent study, plasma concentrations of clozapine and its metabolites were determined in 6 patients with schizophrenia stabilized on clozapine therapy (200-400 mg/d) before and after treatment with sodium valproate (900-1200 mg/d) for 4 weeks. Mean plasma concentrations of clozapine and its metabolites did not change significantly throughout the study, but there was a trend for clozapine levels to be higher and for norclozapine levels to be lower after valproate. Overall, these findings suggest that valproic acid may have an inhibiting effect on the CYP1A2- or CYP3A4-mediated conversion of clozapine to norclozapine. However, the interaction is unlikely to be clinically significant

Locally Sensitive Backtranslation Based On Multiple Sequence Alignment
Backtranslation is the process of decoding an amino
acid sequence into a corresponding nucleic acid. Classical methods
are based on the construction of a codon usage table by
clustering and detection of the most probable codon used for
each amino acid. In this paper we present a new method for
backtranslation which is sensitive to the local position of the
amino acid in the input sequence. The method makes use of
multiple sequence alignment of the set of proteins under analysis.
A local codon usage table stores for each amino acid X and
for each position of X in the alignment the most used codon.
We compared our method with EMBOSS using both ClustalW
and AntiClustAl for multiple sequence alignment. Experiments
showed that our method outperforms EMBOSS in terms of
precision of backtranslation: the matching between the proteins
obtained by our method and the original protein templates is
clearly superior to that obtained by EMBOSS. This enforces the
validity of a locally sensitive approach
Effect of fluoxetine on the plasma concentrations of clozapine and its major metabolites in patients with schizophrenia
The effect of fluoxetine on the plasma concentrations of clozapine and its major metabolites was studied in 10 schizophrenic patients with residual negative symptoms. Patients stabilized on clozapine therapy (200-450 mg/day) received additional fluoxetine (20 mg/day) for eight consecutive weeks. During fluoxetine administration, mean plasma concentrations of clozapine, norclozapine and clozapine N-oxide increased significantly by 58%, 36% and 38%, respectively. There was no difference in negative symptomatology, as measured by the Scale for Assessment of Negative Symptoms, and the drug combination was generally well tolerated. The concomitant elevation in plasma levels of clozapine and its major metabolites suggests that fluoxetine inhibits the metabolism of clozapine by affecting pathways other than N-demethylation and N-oxidation. Close monitoring of clinical response and, possibly, plasma clozapine levels is recommended whenever fluoxetine is given to patients stabilized on clozapine therapy
