    Background: Autism spectrum disorder (ASD) is a chronic and persistent pervasive developmental disorder (PDD) whose characteristic deficit is represented by social difficulties, semantic–pragmatic alterations and a limited, unusual and repetitive pattern of interests and be-haviors. Specifically, individuals with high-functioning autism (HFA) frequently exhibit associated internalizing symptoms that are not part of the diagnostic criteria but which, nonetheless, tend to impair daily functioning. In this study, we investigated how some forms of treatment could be useful in subjects with HFA who display internalizing symptoms. Theoretical background relates to standard cognitive therapy (SCT) and rational education training with mindfulness (M-ERE). Methods: In this study, we investigated how some forms of treatment could be useful in subjects with HFA and internalizing symptoms, focusing on standard cognitive therapy (SCT) and mindfulness associated with emotional rational education training (M-ERE). We selected two groups of HFA patients with significant internalizing symptoms and performed two different forms of treatment for six months: SCT and M-ERE. The aim of the study was to verify the effectiveness of an M-ERE protocol with respect to anxious and depressive symptoms in subjects with HFA. Furthermore, we wanted to compare the results obtained with this combined treatment with those obtained in HFA subjects treated with SCT. Results: Our analyses showed an improvement in the internalizing symptoms (especially those related to the anxiety dimension) of the group that followed a treatment based on mindfulness and rational emotional education for 6 months compared to the group that had instead performed a 6-month treatment based on the SCT. Conclusions: Our hypotheses were supported by the results, which highlighted the efficacy of mindfulness-based interventions in the treatment of internalizing symptoms in adolescents with HFA, and specifically showed that an M-ERE intervention appears more effective in managing anxiety compared to treatment with SCT and appears to be equally effective in the management of depressive symptoms. Not only was the M-ERE treatment effective for the management of anxious and depressive symptoms in subjects with HFA, but the efficacy for the management of anxious symptoms was greater than the SCT treatment

    Isoflavones in aglycone solution enhance ultraviolet B-induced DNA damage repair efficiency.

    The isoflavones daidzein and genistein are natural compounds which have anti-inflammatory and photoprotective activities, and may be effective in the repair of ultraviolet (UV)-induced photodamage. In this study, an alcoholic solution of aglycone isoflavones with a genistein:daidzein ratio of 1:4 [Rottapharm (RPH)-aglycone] was examined for its effects on the repair of DNA damage induced by a single dose of UVB irradiation (20 mJ/cm2). For this purpose, human skin cells were first UVB-irradiated and then treated with RPH-aglycone. Comet assay analysis was used to estimate the UVB-induced DNA damage at different time points after treatment by measuring the tail moment parameter. We found that treatment with 10 μmol/L RPH-aglycone solution resulted in a significantly reduced tail moment at 1 h after treatment, and 34-35% enhancement of damage repair at 4 h after treatment. These results suggest that isoflavone aglycones are protective against UVB-induced DNA damage. © 2014 British Association of Dermatologists

    Treatment with gonadotropin releasing hormone agonists in systemic lupus erythematosus patients receiving cyclophosphamide: a long-term follow-up study

    Background: Cyclophosphamide treatment has been associated with ovarian function impairment. Co-treatment with gonadotropin-releasing hormone-analogue (GnRH-a) seems to be able to prevent this complication. However, even though data are available on neoplastic patients, limited data have been published on systemic lupus erythematosus (SLE) women cohorts. Objectives: To evaluate GnRH-a efficacy on ovarian function preservation in SLE women receiving cyclophosphamide treatment. Methods: The authors performed a retrospective study including SLE women requiring cyclophosphamide treatment and compared those treated with and without GnRH-a (case and controls, respectively). All patients were evaluated before cyclophosphamide treatment and every 3 months in the following years. Ovarian function was evaluated using hormonal profiles. Results: The study comprised 33 SLE cyclophosphamide-treated women: 18 co-treated with triptorelin, and 15 controls. The mean follow-up was 8.1 ± 5.1 years (range 4–11). Premature ovarian failure (POF) prevalence was significantly lower in SLE women treated by cyclophosphamide plus triptorelin compared to controls (11.1% vs. 33.3%, P = 0.0002). The occurrence of POF was significantly associated with higher age at the time of cyclophosphamide treatment (P = 0.008). Only patients in the GnRH-a treated group had successful pregnancies. Conclusions: The study provides information about the efficacy of co-treatment with GnRH-a in SLE women receiving cyclophosphamide, as demonstrated by the lower POF incidence compared to untreated subjects, based on long-term follow-up. These results reinforce the use of GnRH-a for fertility preservation in premenopausal SLE patients treated by cyclophosphamide

    Composition and stage dynamics of mitochondrial complexes in Plasmodium falciparum

    Our current understanding of mitochondrial functioning is largely restricted to traditional model organisms, which only represent a fraction of eukaryotic diversity. The unusual mitochondrion of malaria parasites is a validated drug target but remains poorly understood. Here, we apply complexome profiling to map the inventory of protein complexes across the pathogenic asexual blood stages and the transmissible gametocyte stages of Plasmodium falciparum. We identify remarkably divergent composition and clade-specific additions of all respiratory chain complexes. Furthermore, we show that respiratory chain complex components and linked metabolic pathways are up to 40-fold more prevalent in gametocytes, while glycolytic enzymes are substantially reduced. Underlining this functional switch, we find that cristae are exclusively present in gametocytes. Leveraging these divergent properties and stage dynamics for drug development presents an attractive opportunity to discover novel classes of antimalarials and increase our repertoire of gametocytocidal drugs

    A Web-based spatial decision supporting system for land management and soil conservation

    Abstract. Today it is evident that there are many contrasting demands on our landscape (e.g. food security, more sustainable agriculture, higher income in rural areas, etc.) as well as many land degradation problems. It has been proved that providing operational answers to these demands and problems is extremely difficult. Here we aim to demonstrate that a spatial decision support system based on geospatial cyberinfrastructure (GCI) can address all of the above, so producing a smart system for supporting decision making for agriculture, forestry, and urban planning with respect to the landscape. In this paper, we discuss methods and results of a special kind of GCI architecture, one that is highly focused on land management and soil conservation. The system allows us to obtain dynamic, multidisciplinary, multiscale, and multifunctional answers to agriculture, forestry, and urban planning issues through the Web. The system has been applied to and tested in an area of about 20 000 ha in the south of Italy, within the framework of a European LIFE+ project (SOILCONSWEB). The paper reports – as a case study – results from two different applications dealing with agriculture (olive growth tool) and environmental protection (soil capability to protect groundwater). Developed with the help of end users, the system is starting to be adopted by local communities. The system indirectly explores a change of paradigm for soil and landscape scientists. Indeed, the potential benefit is shown of overcoming current disciplinary fragmentation over landscape issues by offering – through a smart Web-based system – truly integrated geospatial knowledge that may be directly and freely used by any end user (www.landconsultingweb.eu). This may help bridge the last very important divide between scientists working on the landscape and end users

    Imaging the three-dimensional architecture of the Middle Aterno basin (2009 L’Aquila earthquake, Central Italy) using ground TDEM and seismic noise surveys: preliminary results

    Get PDF
    We present preliminary results from a multidisciplinary geophysical approach applied to the imaging of the threedimensional architecture of the Middle Aterno basin, close to the epicentral area of the 2009 L’Aquila earthquake (central Italy). We collected several time domain electromagnetic soundings (TDEM) coupled with seismic noise measurements focusing on the characterization of the bedrock/infill interface. Our preliminary results agree with existing geophysical data collected in the area, and show that the southeastern portion of the basin is characterized by a deepening of the Mesozoic-Tertiary bedrock down to a depth of more than 450 m. We found that a joint use of electromagnetic and seismic methods significantly contributes in obtaining new insights on the 3D geometry of the Middle Aterno basin. Moreover, we believe that our combined approach based on TDEM and noise measurements can be adopted to investigate similar geological settings elsewhere.PublishedPescina (AQ)2T. Tettonica attivaope
