“The role of diagnostics in the restoration project”

Over the last few years, in the field of restoration and conservation, the techniques used to evaluate the extent of damage are becoming increasingly more important before carrying out any work on a historical building. The diagnostic phase is the instrumental, methodological and procedural means of guidance and control during the preliminary cognitive examinations of the building which requires work. For this reason, in the restoration project, the procedural sequence is heavily based to the cognitive phase. In order to evaluate the conservational state of a structure correctly, it is necessary to understand the symptoms of the degradation and the principal cause. When this correlation is unclear there follows the planning and carrying out of a series of cognitive investigations. There is a preference in using indirectly destructive or non destructive investigative techniques to evaluate the state of the damage and degradation of monuments. These tests, which are carried out in situ, are based on identifying global physical properties present in the walls or the walls’ components and provide information about their behaviour. This study presents the planning and implementation of a series of surveys, carried out in situ, preliminary to structural consolidation and redevelopment work on a medieval castle: the castle of Cancellara (South Italy)

Validity and reliability of the Structured Clinical Interview for Depersonalization-Derealization Spectrum (SCI-DER).

This study evaluates the validity and reliability of a new instrument developed to assess symptoms of depresonalization: the Structured Clinical Interview for the Depersonalization-Derealization Spectrum (SCI-DER). The instrument is based on a spectrum model that emphasizes soft-signs, sub-threshold syndromes as well as clinical and subsyndromal manifestations. Items of the interview include, in addition to DSM-IV criteria for depersonalization, a number of features derived from clinical experience and from a review of phenomenological descriptions. Study participants included 258 consecutive patients with mood and anxiety disorders, 16.7% bipolar I disorder, 18.6% bipolar II disorder, 32.9% major depression, 22.1% panic disorder, 4.7% obsessive compulsive disorder, and 1.5% generalized anxiety disorder; 2.7% patients were also diagnosed with depersonalization disorder. A comparison group of 42 unselected controls was enrolled at the same site. The SCI-DER showed excellent reliability and good concurrent validity with the Dissociative Experiences Scale. It significantly discriminated subjects with any diagnosis of mood and anxiety disorders from controls and subjects with depersonalization disorder from controls. The hypothesized structure of the instrument was confirmed empirically

Supraspinal inactivation of mitochondrial superoxide dismutase is a source of peroxynitrite in the development of morphine antinociceptive tolerance.

Effective treatment of chronic pain with morphine is limited by decreases in the drug’s analgesic action with chronic administration (antinociceptive tolerance). Because opioids are mainstays of pain management, restoring their efficacy has great clinical importance. We have recently reported that formation of peroxynitrite (ONOO(−), PN) in the dorsal horn of the spinal cord plays a critical role in the development of morphine antinociceptive tolerance and have further documented that nitration and enzymatic inactivation of mitochondrial superoxide dismutase (MnSOD) at that site provides a source for this nitroxidative species. We now report for the first time that antinociceptive tolerance is also associated with the inactivation of MnSOD at supraspinal sites. Inactivation of MnSOD led to nitroxidative stress as evidenced by increased levels of products of oxidative DNA damage and activation of the nuclear factor poly (ADP-ribose) polymerase in whole brain homogenates. Co-administration of morphine with potent Mn porphyrin-based peroxynitrite scavengers, (MnTE-2-PyP(5+) and MnTnHex-2-PyP(5+)) (1) restored the enzymatic activity of MnSOD, (2) attenuated PN derived nitroxidative stress, and (3) blocked the development of morphine induced antinociceptive tolerance. The more lipophilic analogue, MnTnHex-2-PyP(5+) was able to cross the blood brain barrier at higher levels than its lipophylic counterpart MnTE-2-PyP(5+) and was about 30 fold more efficacious. Collectively, these data suggest that peroxynitrite mediated enzymatic inactivation of supraspinal MnSOD provides a source of nitroxidative stress, which in turn contributes to central sensitization associated with the development of morphine antinociceptive tolerance. These results support our general contention that PN-targeted therapeutics may have potential as adjuncts to opiates in pain management

Co-design and evaluation of the feasibility and the efficacy of a multiple-targeted adapted physical activity intervention to promote quality of life, well-being and physical activity levels in pregnant women: The “well-done!” study protocol

Background: Regular physical activity (PA) practice during pregnancy offers health and fitness benefits for both mother and baby. Therefore, healthy pregnant women with no contraindi-cations to exercise should be encouraged to perform PA. Nevertheless, their levels of PA are gener-ally low. The aim of the WELL-DONE! Study is to co-design an adapted physical activity intervention (APAI) for pregnant women to include in childbirth preparation classes (CPCs) evaluating its feasibility and efficacy on quality of life (QoL), PA levels and other outcomes. Methods: A quasi-experimental study was divided in two progressive stages. First, APAI was developed in collabo-ration with pregnant women and midwives using focus groups; second, APAI’s efficacy was evaluated comparing two groups: the experimental group engaged in the CPCs integrated with 1 h/week of the APAI administered by midwives and the control group participating in the standard CPCs. Pre-post evaluation was carried out in three stages through questionnaires and tests. Data analysis involved the combination of qualitative and quantitative methodologies. Discussion: Find-ings from the WELL-DONE! Study will help to assess the feasibility, sustainability, and efficacy of incorporating APAI inside CPCs as a new public health strategy oriented to QoL, well-being, and PA level improvements

Body composition and metabolic changes during a 520\u2011day mission simulation to Mars

Purpose The \u201cMars-500 project\u201d allowed to evaluate the changes in psychological/physiological adaptation over a prolonged confinement, in order to gather information for future missions. Here, we evaluated the impact of confinement and isolation on body composition, glucose metabolism/insulin resistance and adipokine levels. Methods The \u201cMars-500 project\u201d consisted of 520 consecutive days of confinement from June 3, 2010 to Nov 4, 2011. The crew was composed of six male subjects (three Russians, two Europeans, and one Chinese) with a median age of 31 years (range 27\u201338 years). Results During the 520-day confinement, total body mass and BMI progressively decreased, reaching a significant difference at the end (417 days) of the observation period ( 12 9.2 and 12 5.5%, respectively). Fat mass remained unchanged. A progressive and significant increase of fasting plasma glucose was observed between 249 and 417 days (+ 10/+ 17% vs baseline), with a further increase at the end of confinement (up to + 30%). Median plasma insulin showed a non-significant early increment (60 days; + 86%). Total adiponectin halved ( 12 47%) 60 days after hatch closure, remaining at this nadir ( 12 51%) level for a further 60 days. High molecular weight adiponectin remained significantly lower from 60 to 168 days. Conclusions Based on these data, countermeasures may be envisioned to balance the potentially harmful effects of prolonged confinement, including a better exercise program, with accurate monitoring of (1) the individual activity and (2) the relationship between body composition and metabolic derangement

Genetic polymorphisms of glutathione S-transferases GSTM1, GSTT1, GSTP1 and GSTA1 as risk factors for schizophrenia

Oxidative damage is thought to play a role in the predisposition to schizophrenia. We determined if the polymorphisms of the GSTP1, GSTM1, GSTT1 and GSTA1 genes, which affect the activity of these enzymes against oxidative stress, have a role as susceptibility genes for schizophrenia, analyzing 138 schizophrenic patients and 133 healthy controls. We found that the combination of the absence of GSTM1 gene with the of the GSTM1 gene with the polymorphism GSTA1*B/*B, and the presence of the GSTT1 gene, represents a risk factor for schizophrenia, indicating that the combination of different GST polymorphisms has a role in the predisposition to schizophrenia, probably affecting the capacity of the cell to detoxify the oxidized metabolites of catecholamines
