Exploring Self‐criticism: Confirmatory Factor Analysis of the FSCRS in Clinical and Nonclinical Samples
Authors: Castilho Paula , Pinto‐Gouveia José , Duarte Joana 
Published: December 2013

The Forms of Self‐criticizing/Attacking and Self‐reassuring Scale (FSCRS) is a self‐report questionnaire that assesses the forms of self‐criticism and self‐reassurance. The aim of this study was to explore the latent structure of the FSCRS in nonclinical and clinical samples. Data from 381 participants from the general population and from 304 participants from clinical settings were subjected to confirmatory factor analyses to explore several structural models reflecting alternative representations of the FSCRS dimensionality. Overall, the model with the best fit to the data, in both samples, was the three‐factor model (inadequate self, hated self and reassured self subscales) replicating the FSCRS original structure. The scale showed good psychometric characteristics, and the three factors discriminated between the clinical and nonclinical samples. To our knowledge, this is the first study to confirm the factor structure of the FSCRS in a purely clinical sample, and to test alternative models. This study adds to the existent literature that has been supporting the conceptualization of self‐criticism as a multidimensional construct. Given the good psychometric properties of the Portuguese version of the FSCRS, its use is encouraged and recommended for the assessment of self‐criticism in both clinical and research settings.

Our results suggest that self‐criticism is associated with psychopathology indicators and, for this reason, should be addressed in clinical settings. Also, self‐criticism is not a single process, and thus therapists may need to explore in more detail its different forms (i.e., feeling inadequate and hateful feelings for the self).
The FSCRS questionnaire may be an important tool in aiding therapists in assessing their patients, given its ability to discriminate individuals from the normal population and individuals from clinical settings. Thus, self‐criticism is s not only theoretically but also clinically meaningful.
Given the idea that self‐reassuring operates through a different affect system, helping people develop inner warmth and compassion for the self may be important to counteract feelings of self‐hatred and self‐attack.
Synthesis of Heterodimetallic Complexes by Reaction of a Terminal Phosphido Pt Complex with Metal‐Based Nucleophiles and Electrophiles
Authors: Latronico Mario , Todisco Stefano , Gallo Vito , Englert Ulli , Mastrorilli Piero 
Published: December 2013

AbstractThe complex trans‐[PtCl(PCy2)(PHCy2)2] (1) possesses a terminal phosphanido group (PCy2) and a chloride ligand, which render it a good candidate for the synthesis of phosphanido‐bridged heterodimetallic species (PHCy2)2Pt(μ‐PCy2)M–L by reaction either with carbonyl metalates, as metal‐based nucleophiles, or with metal‐based electrophiles. The heterodinuclear complexes [(PHCy2)2Pt(μ‐PCy2)Co(CO)3](Pt–Co) (2), [(PHCy2)2Pt(μ‐PCy2)Mo(CO)2Cp](Pt–Mo) (3), and [(PHCy2)2Pt(μ‐PCy2)W(CO)2Cp](Pt–W) (4) are obtained by reaction of 1 with the carbonyl metalates Na[Co(CO)4], Na[Mo(CO)3Cp] and Na[W(CO)3Cp], respectively. Although 2 is reluctant to react with carbon monoxide, 3 and 4 are promptly carbonylated under ambient conditions to afford mixtures of the cis and trans isomers of [(PHCy2)(CO)Pt(μ‐PCy2)M(CO)2Cp] (M = Mo or W), which interconvert through dissociation/reassociation of the CO ligand coordinated to the Pt centre. The reaction of 1 with AuCl(PPh3) leads to the formation of the trinuclear Pt2Au complexes cis‐ and trans‐[{Cl(PHCy2)2Pt(μ‐PCy2)}2Au]Cl (cis‐ and trans‐[8]Cl), in which a Au atom bridges two molecules of 1 through the originally terminal phosphanide ligands.
Marine Toxins in Italy: The More You Look, the More You Find
Authors: Ciminiello Patrizia , Dell'Aversano Carmela , Forino Martino , Tartaglione Luciana 
Published: December 2013

AbstractHarmful Algal Blooms (HABs) are massive proliferations of toxic algal species that occur under appropriate climatic and environmental conditions. HABs can exert their adverse impacts both on the environment and on particular living organisms through the production of marine biotoxins. Consumption of contaminated seafood or direct exposure to marine biotoxins (swimming, aerosols etc.) can result in human illness or even death. Thousands of cases of marine‐toxin‐related human poisoning are reported every year on a global basis. In Italy, research on marine biotoxins has shown a continuously changing toxin profile, with most of the toxin classes known so far being found at some point in seafood and seawater. Starting in the late 1980s, with the first finding of a marine biotoxin, okadaic acid, along the Italian coastline, a number of other classes of marine toxins – namely, yessotoxins, pectenotoxins, saxitoxins, domoic acid, spirolides, palytoxins and azaspiracids – have been found. Here we provide an overview, in chronological order, of the many classes of marine biotoxins that have infested Italian seawater over the past 25 years.
Enhanced osteoconductivity of sodium‐substituted hydroxyapatite by system instability

Published: December 2013

AbstractThe effect of substituting sodium for calcium on enhanced osteoconductivity of hydroxyapatite was newly investigated. Sodium‐substituted hydroxyapatite was synthesized by reacting calcium hydroxide and phosphoric acid with sodium nitrate followed by sintering. As a control, pure hydroxyapatite was prepared under identical conditions, but without the addition of sodium nitrate. Substitution of calcium with sodium in hydroxyapatite produced the structural vacancies for carbonate ion from phosphate site and hydrogen ion from hydroxide site of hydroxyapatite after sintering. The total system energy of sodium‐substituted hydroxyapatite with structural defects calculated by ab initio methods based on quantum mechanics was much higher than that of hydroxyapatite, suggesting that the sodium‐substituted hydroxyapatite was energetically less stable compared with hydroxyapatite. Indeed, sodium‐substituted hydroxyapatite exhibited higher dissolution behavior of constituent elements of hydroxyapatite in simulated body fluid (SBF) and Tris‐buffered deionized water compared with hydroxyapatite, which directly affected low‐crystalline hydroxyl‐carbonate apatite forming capacity by increasing the degree of apatite supersaturation in SBF. Actually, sodium‐substituted hydroxyapatite exhibited markedly improved low‐crystalline hydroxyl‐carbonate apatite forming capacity in SBF and noticeably higher osteoconductivity 4 weeks after implantation in calvarial defects of New Zealand white rabbits compared with hydroxyapatite. In addition, there were no statistically significant differences between hydroxyapatite and sodium‐substituted hydroxyapatite on cytotoxicity as determined by BCA assay. Taken together, these results indicate that sodium‐substituted hydroxyapatite with structural defects has promising potential for use as a bone grafting material due to its enhanced osteoconductivity compared with hydroxyapatite. © 2013 Wiley Periodicals, Inc.

Tips for double balloon enteroscopy in patients with Roux‐en‐Y reconstruction and modified Child surgery
Authors: Shimatani Masaaki , Takaoka Makoto , Okazaki Kazuichi 
Published: December 2013

AbstractPancreatobiliary disease in patients with altered anatomic intestine is one of the most difficult cases for pancreatobiliary endoscopic therapies and diagnosis. There are two major challenges to overcome to complete the procedure. The first challenge is the deep insertion to the blind end. The second challenge is the endoscopic retrograde cholangiopancreatography (ERCP)‐related intervention. Impairing either success means the incompletion of the procedure. The double balloon enteroscope (DBE), which has been recently developed, enabled the deep intubation to the blind end. Especially, using the scopes with a short working length allowed us to perform the ERCP‐related interventions with a high success rate. Generally, ERCP using double balloon endoscope (DB‐ERCP) in patients with altered gastrointestinal anatomy has been established. We introduce our standard technique for DB‐ERCP and provide several tips for insuring a successful procedure.
