Novel bioactive bromopyrrole alkaloids from the Mediterranean sponge Axinella verrucosa

2005

The Mediterranean sponge Axinella verrucosa has been investigated for its alkaloid composition and has been found to produce a complex mixture of bromopyrrole alkaloids. Along with the previously isolated compounds 5-18, four novel alkaloids of this class, compounds 1-4, have been isolated, and their structures established through spectroscopic methods. Compounds 1-4 were found to display neuroprotective activity against the agonists serotonin and glutamate in vitro.

Assessment of the Vegetation Parameters of Almond and Vine Plants for Designing a Compact Tractor

2018

The aim of this research is to assess the vegetation parameters of almond and vine plants, aimed at designing a compact tractor suitable for these orchards. The research is part of the Italian project TRACLAS, involving the Universities of Palermo, Milan, Bari, “Tuscia” of Viterbo and Agricultural Research and Economics - Research Unit for Agricultural Engineering (CREA-ING) of Treviglio (Bergamo). Based on the results of the surveys carried out in a sample of almond and vine farms, it was possible to define the vegetation parameters that will allow to design a very low and narrow tractor equipped with a fixed ROPS and suitable for these orchards.

Children Self-Concept and Family Image in the Protective Context

2009

Frequently the negligence or maltreatment experiences requires an estrangement of children by their family contexts (Giordano C., Giannone F., 2005, Bastianoni P., 2000, Emiliani F., Bastianoni P., 1993). This research examine if and which relational conditions consents to begin again a normal development and to form a new self-concept in another protective context. Particularly it evaluate the change of family and self image during the permanently time in this context. Sample is constituted by 38 children and adolescents guest in three “family house” of Palermo city. In order to collect data are used: DSSVF; TRI, TMA. The tests are analyzed through the use of specific landing procedure of …

Developing drug strategies for the neuroprotective treatment of acute ischemic stroke

2015

Developing new treatment strategies for acute ischemic stroke in the last twenty years has offered some important successes, but also several failures. Most trials of neuroprotective therapies have been uniformly negative to date. Recent research has reported how excitatory amino acids act as the major excitatory neurotransmitters in the cerebral cortex and hippocampus. Furthermore, other therapeutic targets such as free radical scavenger strategies and the anti-inflammatory neuroprotective strategy have been evaluated with conflicting data in animal models and human subjects with acute ischemic stroke. Whereas promising combinations of neuroprotection and neurorecovery, such as citicoline,…

Pneumococcal vaccination in celiac disease

2019

Introduction: Celiac disease (CD) is an immune-mediated disorder associated with gluten exposure in genetically predisposed subjects. Areas covered: Infectious disease is one of the causes of morbidity and mortality in CD patients. Invasive streptococcus pneumoniae (pneumococcus) is a particularly dangerous morbid condition in both the general population and celiac patients. Pneumococcal vaccination is the most effective means for its prevention. Expert opinion: In CD, evaluation of spleen function should be useful to select patients who may benefit from vaccination to reduce the risk of pneumococcal disease. Different strategies could be employed: physicians could search for signs of hypos…

Helicobacter pylori and Barrett’s esophagus: a protective factor or a real cause?

2017

Nothwithstanding the definite aethiopathogenetic path of certain diseases, the relationship between Helicobacter Pylori (H. Pylori) and barrett's esophagus (BE), a condition that increases the risk for dysplasia and consequently adenocarcinoma of the distal esophagus and esophagogastric junction, remains uncertain. this paper reviews the current scientific literature with emphasis on the protective correlation between H. Pylori infection and BE, and demonstrates that a causal relathionship has not been disproved with certainty. Furthermore, H. Pylori infection could pose a risk for the onset of gastroesophageal reflux disease (GERD), which could in turn trigger BE, a precancerous lesion and…

The effectiveness of eco-guided infiltrations with high molecular weight associated with administration of oral chondroprotective supplements in oste…

2012

Osteoarthritis does not mean a degenerative articular process only but a pathologic expression of wear, inflammation and immunological imbalance of the joints. Our study has the aim to demonstrate the effectiveness of eco-guidate infiltrations with high molecular weight associated with administration of oral chondroprotective supplements (glucosamine solfate, chondroitin sulphate, hydrolyzed collagen type II, hyaluronic acid and L carnitine fumarate) in comparison with the only treatment with ecoguided infiltrations with hyaluronic acid in patients suffering from primary osteoarthiritis of the hip.

Career pursuit pathways among emerging adult men and women : Psychosocial correlates and precursors

2014

The present study examined career pursuit pathways in 100 Israeli emerging adults (54 men) who were followed from age 22 to 29. Employing a semi-structured interview at the age of 29, participants were asked about current work and educational status, work and educational goals and status changes in recent years, and to reflect on the meaning of the processes they followed. Analyses of interviews yielded four distinctive career pursuit pathways that were associated with different levels of concurrent well-being: Consistent Pursuit, Adapted Pursuit, Survivors, and Confused/Vague. Self-criticism, efficacy, and level of motivation measured seven years earlier predicted pathway affiliation at 2…

What keeps young adults in permanent poverty? A comparative analysis using ECHP

2009

Abstract Previous studies suggest that there are strong differences in the rates of youth poverty across European countries. Rather surprisingly, it is found to be high in Scandinavian countries, and relatively speaking, lower in Mediterranean and Anglo-Saxon countries. This somewhat unexpected finding prompts the question whether the incidence of poverty is an appropriate measure of youth disadvantage. Instead of considering poverty rates we consider the length of recorded poverty spells, taking into account explicitly the temporal sequencing of the episodes of poverty. Using the European Community Household Panel, individuals are classified into different groups of poverty permanence, eac…

Sense of coherence and burnout in nursing home workers during the COVID‐19 pandemic in Spain

2021

Abstract Care staff in nursing homes work in a challenging environment, and the COVID‐19 pandemic has exacerbated those challenges in an unprecedented way. On the other hand, the sense of coherence (SOC) is a competence that could help these professionals perceive the situation as understandable, manageable and meaningful. This study aims to analyse the extent to which potential risk and protective factors against burnout have affected nursing home workers during the COVID‐19 pandemic and to assess the contribution of these factors to their burnout. Three hundred forty professionals who worked in nursing homes in Spain completed a survey and reported on their sociodemographic characteristic…
