Hydraulic kinetics of the graft union in different Olea europaea L. scion/rootstock combinations
2007
The hydraulic resistance of young olive trees grafted on rootstocks with contrasting size-controlling potential was measured 30, 90, 360 and 480 days after grafting. Olive (Olea europaea L.) clones inducing plant vigorous growth (Leccino ‘Minerva’, LM) or dwarfing (Leccino ‘Dwarf’, LD) were studied in different scion/rootstock combinations (LD/LD, LD/LM, LM/LD, LM/LM). Plants growing on LD root systems developed lower leaf surface areas (about 50% less) than plants grafted on LM rootstocks. Graft union represented the largest fraction (up to 85%) of whole-plant hydraulic resistance 30 days after grafting, and still represented an important fraction of it 2 months later (40–55%). Four-hundre…
Psychometric properties of the Finnish version of the Young Person's Clinical Outcomes in Routine Evaluation (YP-CORE) questionnaire.
2017
An increasing need exists for suitable measures to evaluate treatment outcome in adolescents. YP-CORE is a pan-theoretical brief questionnaire developed for this purpose, but it lacks studies in different cultures or languages.To explore the acceptability, factor structure, reliability, validity, and sensitivity to change of the Finnish translation of YP-CORE.The study was conducted at the Department of Adolescent Psychiatry, Helsinki University Central Hospital. A Finnish translation was prepared by a team of professionals and adolescents. A clinical sample of 104 patients was asked to complete the form together with BDI-21 and BAI, and 92 of them filled the forms again after a 3-month tre…
Explicit form of the time operator of a gaussian stationary process
2004
We present the time operator theory in the framework of stationary stochastic processes. The main results of the paper is the derivation of the time operator acting on the Fock space associated with a discrete time gaussian stationary process.
Occurence of Bechstein's bat Myotis bechsteini (Chiroptera, Vespertilionidae) in Sicily.
2012
The bat fauna of Sicily is still poorly known and no extensive survey of these mammals on the island has been so far carried out. Here we report on the occurrence of Bechstein’s bat (Myotis bechsteinii) on the island. We recorded this species’ presence at two sites of the Nebrodi mountains (central Sicily) at an elevation of ca. 1500 m a.s.l. The occurrence of M. bechsteinii in Sicily has been regarded as doubtful and not mentioned in recent checklists. Our observations clearly establish that this species does occur on the island and awaits appropriate consideration for conservation actions.
Drawing the Line at Neglected Marine Ecosystems: Ecology of Vermetid Reefs in a Changing Ocean
2016
Vermetid mollusks form reefs that protect coasts from erosion, regulate sediment transport, serve as carbon sinks, and provide habitat for many fish and invertebrates. This biogenic habitat is found in tropical, sub-tropical, and warmtemperate coastal areas, such as Bermuda, oceanic islands in Brazil, and Hawaii, several locations within the Caribbean and the Mediterranean. These reefs are functionally similar to tropical coral fringing reefs but are built by gregarious vermetid gastropods cemented by a crustose coralline algal species, which probably triggers their settlement. Some descriptive studies in different regions worldwide and comparisons among tropical and Mediterranean reefs con…
Methylation decrease of BECN1 gene induced by phytochemical Indicaxantin in Caco2 cells: an epigenetic hypothesis of autophagy
2014
Autophagy is a highly conserved catabolic process that degrades and recycles intracellular components through the lysosomes [1]. The role of this process in tumorigenesis and tumor progression is controversial: in the early stages, it can block tumor growth and conversely it can promote its progression in the later stages [2]. The tumor suppressor BECN1 gene, encodes the protein Beclin 1, a marker of autophagy down-regulated in several types of cancer, such as colorectal cancer [3]. There are a lot of both genetic and environmental risk factors for colorectal cancer, including diet: for this reason, in accordance with epidemiological studies, consumption of foods rich in phytochemicals is w…
METHYLOMIC SIGNATURE AND MOLECULAR MODELLING TO BETTER UNDERSTAND AUTOPHAGY INDUCED BY PHYTOCHEMICAL IN CACO-2 CELLS
2019
The binomial “autophagy-cancer” is intricate and methylomic studies can help to understand it by changing point of view from a gene level to an -omic one. Recently, autophagy-modulating properties of several phytochemicals have attracted attention in anticancer research. We evaluated whether Indicaxanthin (IND), the peculiar known beneficial phytochemical of prickly pear, seasonally available in the southern Italy, could induce autophagy in Caco2 cells, and whether it results from an epigenomic modification and/or a direct molecular interaction. IND increased autophagy in Caco-2 cells; the methylomic signature, obtained by Reduced Representation Bisulfite Sequencing (15 million of clusters)…
Metilazione del DNA in artrite reumatoide
2005
Lo stato di metilazione del DNA genomico e del gene PTHrP è stato valutato con tecniche molecolari e citogenetiche in artrite reumatoide (AR), patologia autoimmune caratterizzata anche da alta incidenza di linfomi e da ipercalcemia per overespressione del gene PTHrP. La metilazione del DNA, infatti, ha un ruolo critico nello sviluppo delle malattie neoplastiche; il gene PTHrP avendo tre promotori uno dei quali contiene un’isola CpG è un buon candidato per la deregolazione da alterato pattern di metilazione locale. Le indagini sulla metilazione genomica, condotte su DNA estratto da sangue periferico di pazienti e di donatori e amplificato in reazioni di Methylation-Sensitive Arbitrarily Prim…
