A clinical heritage of empirical research. In memory of Jeremy Safran
This is Part II of a special issue, Research in Psychotherapy: Psychopathology, Process and Outcome, dedicated in memory of our colleague Jeremy Safran (Part I was published in April 2019). All of the contributions (theoretical papers, clinical cases, qualitative and quantitative studies) presented in this second part of the special issue focus on the topic of ruptures and resolutions in the therapeutic alliance. Each paper demonstrates a unique approach, perspective, and methodology
Chemical–physical characteristics, polyphenolic content and total antioxidant activity of three Italian-grown pomegranate cultivars
Background
In Mediterranean countries, there is an increasing demand for pomegranate fruits due to their antioxidant properties and nutritional values. The large diffusion of new genotypes and cultivars requires the knowledge of all fruit characteristics in connection with the cultivation area, to satisfy the market demand. This study seeks to determine the fruit quality attributes and nutraceutical values of three pomegranate cultivars (Wonderful, Acco and Kamel) grown in the Mediterranean climate.
Methods
The fruits were evaluated for their main physico-chemical traits (weight, volume, height, width, thickness, total arils number, total arils weight, juiciness, fruit index, peel index and total soluble solids content/titratable acidity ratio), bioactive compounds (total phenolic content and total anthocyanin content) and antioxidant activities (radical scavenging activity and ferric reducing power).
Results: The data showed that Acco fruit is bigger, juicier and sweeter when compared with the cultivars Wonderful and Kamel. Wonderful is the smallest, least juicy and least sweet but the reddest among all the studied cultivars. Regarding the phenolic compounds and antioxidant activity (radical scavenging activity and ferric reducing power), cultivar Wonderful has the highest values and cultivar Acco contains the most anthocyanin content.
Conclusions
This study showed that pomegranate cultivars grown in the Mediterranean area exhibit an appreciable quality, but there are significant differences in quality properties of the arils and juice
Possible Role of the Transglutaminases in the Pathogenesis of Alzheimer's Disease and Other Neurodegenerative Diseases
Transglutaminases are ubiquitous enzymes which catalyze posttranslational modifications of proteins. Recently, transglutaminase-catalyzed post-translational modification of proteins has been shown to be involved in the molecular mechanisms responsible for human diseases. Transglutaminase activity has been hypothesized to be involved also in the pathogenetic mechanisms responsible for several human neurodegenerative diseases. Alzheimer's disease and other neurodegenerative diseases, such as Parkinson's disease, supranuclear palsy, Huntington's disease, and other polyglutamine diseases, are characterized in part by aberrant cerebral transglutaminase activity and by increased cross-linked proteins in affected brains. This paper focuses on the possible molecular mechanisms by which transglutaminase activity could be involved in the pathogenesis of Alzheimer's disease and other neurodegenerative diseases, and on the possible therapeutic effects of selective transglutaminase inhibitors for the cure of patients with diseases characterized by aberrant transglutaminase activity
Transglutaminase inhibition: possible therapeutic mechanisms to protect cells from death in neurological disorders.
Neuronutraceuticals Modulate Lipopolysaccharide- or Amyloid-β 1-42 Peptide-Induced Transglutaminase 2 Overexpression as a Marker of Neuroinflammation in Mouse Microglial Cells
Background: Tissue type 2 Transglutaminase (TG2, E.C. 2.3.2,13) is reported to be involved in phagocytosis of apoptotic cells in mouse microglial BV2 cells and peripheral macrophages. In this study, by using Lipopolysaccharide (LPS)- or Amyloid-beta 1-42 (Abeta 1-42) peptide-stimulated mi-croglial cell line BV2 and mouse primary microglial cells, we examined the effects of different neuronutraceutical compounds, such as Curcumin (Cu) and N-Palmitoylethanolamine (PEA), known for their anti-inflammatory activity, on TG2 and several inflammatory or neuroprotective biomarkers expressions. Methods: Mouse BV2 cells were treated with LPS or Abeta1-42 in presence of Curcumin or PEA, in order to evaluate the expression of TG2 and other inflammatory or neuro-protective markers by RealTime PCR and Western Blot analyses. Results: Curcumin and PEA were capable to reduce TG2 expression in mouse microglial cells during co-treatment with LPS or Abeta 1-42. Conclusions: The results show the role of TG2 as an important marker of neuroinflamma-tion and suggest a possible use of Curcumin and PEA, in order to reduce LPS- or Abeta1-42-induced TG2 overexpression in mouse microglial cells
Tree-Ripe Mango Fruit: Physicochemical Characterization, Antioxidant Properties and Sensory Profile of Six Mediterranean-Grown Cultivars
Some of the key components that contribute to the acceptance of high-quality fresh mangoes by consumers are its flavour, odour, texture and chemical constituents that depend mainly on level of maturity. In the European market, the demand for tree-ripened fruit has increased in recent decades. Nevertheless, the qualitative response and the marketable characteristics of tree-ripened mango fruit grown in the Mediterranean area are not yet studied. Tree-ripened fruits of cv Keitt, Glenn, Osteen, Maya, Kensington Pride and Tommy Atkins were submitted to analytical (fruit weight, transversal diameter, longitudinal diameter, flesh firmness, total soluble solid content, titratable acidity, seed weight, peel weight, percentage of flesh and fibre, ash content, fat content, carbohydrate content, riboflavin, niacin, thiamin, K, Na, Ca, Mg, Fe, Cu, Mn and Zn contents, ascorbic acid and vitamin A) and sensory evaluations. Significant differences were observed for sensory and physicochemical characteristics in a cultivar-dependent manner. The mango Keitt, in addition to its interesting physicochemical traits, content of protein and vitamin, has a higher sensory appeal. Glenn fruit showed more suitable weight, flesh firmness, soluble solids, vitamin content, total antioxidant activity and total polyphenolics content; Maya had the lowest titratable acidity and the highest soluble solid content, whereas Tommy Atkins revealed preferable ground colour, total antioxidant activity, and vitamin B2 and vitamin C contents. Tree-ripened fruits grown in the Mediterranean climate show interesting peculiarities in regard to fresh market requirements. The analytical-sensory approach established a qualitative characterization of the six observed cultivars
Toxic metals in Loggerhead sea turtles (Caretta caretta) stranded freshly dead along Sicilian coasts
Abstract
Background: The Loggerhead sea turtle (Caretta caretta) is a marine reptile belonging
to a monophyletic group of chelonians. As these animals are long-lived, they have the
ability to accumulate pollutants.
Aim: To collect epidemiological data on toxic metals in marine Loggerhead sea turtles.
Materials and Methods: Forty Loggerhead sea turtles comprising 25 males and 15
females stranded freshly dead between 2013 and 2018 along the coasts of Sicily,
Southern Italy, were examined for arsenic, cadmium, and lead accumulation in muscle
and adipose tissues by means of a validated ICP-MS method. A modified K index as a
growth condition factor, namely Fulton's K index, was used. Samples were tested in
duplicate. A Wilcoxon rank sum test was carried out to evaluate metal contents
differences between muscle and adipose tissues and between genders.
Results: The Fulton's K index suggested a good body condition of the C. caretta
recovered with mean values of 5.34±3.40 (n=40; ±SD). Detectable concentrations of
lead were found in 70% of the samples analysed with mean values of 0.65±1.67 mg/kg
wet weight and 0.51±1.29 mg/kg wet weight in muscle and adipose tissues,
respectively. No significant differences in arsenic, cadmium, and lead were detected
between genders. In addition, no significant correlation was found between modified K
index and concentrations of arsenic, cadmium, and lead.
Clinical relevance: Findings on muscle and adipose tissues suggest chronic exposure of
Caretta caretta to high concentrations of especially lead which might negatively affect
health and welfare of these marine turtles although body condition was good
