    Questo saggio illustra la modernità e le prospettive della Convenzione delle Nazioni Unite contro il crimine organizzato transnazionale a venti anni dalla sua adozione. L’autore si sofferma sul potenziale contributo che la cosiddetta “Risoluzione Falcone”potrebbe apportare al rafforzamento della cooperazione internazionale in relazione alle misure di prevenzione patrimoniali, alla cooperazione giudiziaria e nelle indagini transnazionali, in particolare grazie a nuovi strumenti quali i “joint investigative bodies”, i magistrati di collegamento e l’uso di tecniche investigative speciali.This essay illustrates the modernity and prospects of the United Nations Convention against Transnational Organized Crime twenty years after its adoption. The author focuses on the potential contribution that the so-called "Falcone Resolution" could bring to the strengthening of international cooperation in the field of preventive measures on assets, judicial cooperation, and transnational investigations, in particular thanks to new tools such as joint investigative bodies, liaison magistrates and the use of special investigative techniques

    Crasiella diplura from Sweden and Crasiella sp. from Italy were studied alive and with transmission electron microscopy (TEM). The two species are simultaneous hermaphrodites and share the same reproductive system lay-out: paired ovaries extend along the posterior part of the intestine and join mid-dorsally, while bilateral,club-shaped testes lie at the sides of the anterior gut, extending as deferentia that fuse on the mid-ventral plane and open into a single pore; gametes mature in a caudocephalicand centripetal direction. The bulky, sac-like, frontal organ is lined by a simple epithelium and lies dorsolaterally to the intestine, on the left side of the body.The spindle-shaped caudal organ is musculo-glandular and is located ventrolaterally to the gut on the right side. It is characterized by the presence of a roughly Y-shapedinternal channel that opens into two pores close to each other, which function for the intake and outlet of the (auto)sperm, respectively. The spermatozoa, which arepeculiar and similar in the two species, are characterized by a long and complex acrosome consisting of four ultrastructurally distinct regions, three of which findequivalence in other gastrotrich species. The flagellum lacks a striated cylinder. Anatomy and ultrastructure enable us to hypothesize a modality of sperm transfer in Crasiellathat is similar to that observed in Macrodasys

    Energy, environment and sustainable development of the belt and road initiative: The Chinese scenario and Western contributions

    Abstract The Belt and Road Initiative has tremendously increased the interaction of China with the countries involved, pushing forward the integration and comparative phase, based on the main factors affecting the energy, environmental and development scenarios. The indicators of this process are strictly related to the environmental sustainability of projects and infrastructural initiatives which entail aspects regarding climate change, environmental impact, transport management, urbanization and effective utilization of energy. Through this osmotic program, which the Chinese government said in 2013 would be executed from east to west, the contributions Western countries may make to maximize the common efforts are foreseeably very important for the success of the whole BRI and, indirectly, for the harmonization of the very rapid Chinese growth. China held the first position in 2014 for electricity generation (5388 billion kwh/h) and coal production (4.27 billion short tons/year), as well as the second position for petroleum consumption. On the other hand, carbon dioxide emissions were 1.8 times those of the USA in 2015, and transport, urbanization and energy intensity still struggle to attain optimal levels. The quality of productive sectors, research and universities is still low in the world ranking, despite the huge efforts of the Chinese, due to a still slow and cumbersome internationalization process. This article aims to integrate the numerous excellent studies published in the last few years on sustainable development and energy effectiveness within the BRI (Table 1 provides some specific references), by carrying out a systematic analysis of the Chinese energy, environmental and sustainable landscape from a Western perspective, breaking the main areas of the Chinese scenario down into its components and identifying those where the contributions of Western countries can support the gaps coverage. In this respect, the change of viewpoint provided by this study may be beneficial to properly balance the BRI perspective along the east-west axis

    Study Objectives: To evaluate the effect of type 1 narcolepsy (NT1) on anthropometric and endocrine features in childhood/adolescence, focusing on patterns and correlates of weight, pubertal development, and growth in treated and untreated patients. Methods: We collected anthropometric (height, weight, body mass index (BMI) z-scores), pubertal, metabolic, and endocrine data from 72 NT1 patients at diagnosis and all available premorbid anthropometric parameters of patients from their pediatric files (n = 30). New measurements at 1-y reassessment in patients undergoing different treatments were compared with baseline data. Results: We detected a high prevalence of overweight (29.2%), obesity (25%), metabolic syndrome (18.8%), and precocious puberty (16.1%), but no signs of linear growth alterations at diagnosis. According to anthropometric records, weight gain started soon after NT1 onset. At 1-y follow-up reassessment, sodium oxybate treatment was associated with a significant BMI z-score reduction (-1.29 \ub1 0.30, p < 0.0005) after adjusting for baseline age, sex, sleepiness, and BMI. Conclusions: NT1 onset in children/adolescents is associated with rapid weight gain up to overweight/obesity and precocious puberty without affecting growth. In our study, sodium oxybate treatment resulted in a significant weight reduction in NT1 overweight/obese patients at 1-y follow-up

    Simulation of forest harvesting alternative processes and concept design of an innovative skidding winch focused on productivity improvement

    In contexts in which mechanized harvesting is limited, such as in the northwestern Black Sea region of Turkey, it is important to improve timber harvesting productivity while preserving operators' safety and reducing environmental damage. This study aims to introduce a methodology in which the harvesting process is simulated with discrete-event simulation (DES) software in order to identify bottlenecks. An alternative process is compared to the original within the DES software, carrying out further steps oriented to the generation of new innovative product concepts. As a case study, the design of an innovative skidding winch is proposed. The development of the product was focused towards customer satisfaction by collecting customer requirements and identifying quality characteristics with a quality function deployment approach. Contradictions identified in the design phase were solved using the TRIZ contradiction toolkit, generating different product concepts. Inventive solutions provided by TRIZ were designed within parametric CAD software. The concepts were compared in a virtual environment, eventually selecting an optimal solution. The results showed that, with the concept adopted, it is possible to achieve a substantial increase in productivity, from 121% to 133%, in terms of kilograms of logs per hour deposited on the landing

    Muscle regeneration is a complex phenomenon, involving replacement of damaged fibers by new muscle fibers. During this process, there is a tendency to form scar tissue or fibrosis by deposition of collagen that could be detrimental to muscle function. New therapies that could regulate fibrosis and favor muscle regeneration would be important for physical therapy. Low-level laser therapy (LLLT) has been studied for clinical treatment of skeletal muscle injuries and disorders, even though the molecular and cellular mechanisms have not yet been clarified. The aim of this study was to evaluate the effects of LLLT on molecular markers involved in muscle fibrosis and regeneration after cryolesion of the tibialis anterior (TA) muscle in rats. Sixty Wistar rats were randomly divided into three groups: control, injured TA muscle without LLLT, injured TA muscle treated with LLLT. The injured region was irradiated daily for four consecutive days, starting immediately after the lesion using an AlGaAs laser (808 nm, 30 mW, 180 J/cm[superscript 2]; 3.8 W/cm[superscript 2], 1.4 J). The animals were sacrificed on the fourth day after injury. LLLT significantly reduced the lesion percentage area in the injured muscle (p < 0.05), increased mRNA levels of the transcription factors MyoD and myogenin (p < 0.01) and the pro-angiogenic vascular endothelial growth factor (p < 0.01). Moreover, LLLT decreased the expression of the profibrotic transforming growth factor TGF-β mRNA (p < 0.01) and reduced type I collagen deposition (p < 0.01). These results suggest that LLLT could be an effective therapeutic approach for promoting skeletal muscle regeneration while preventing tissue fibrosis after muscle injury.National Institutes of Health (U.S.) (grant R01AI050875)Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorConselho Nacional de Pesquisas (Brazil)Fundação de Amparo à Pesquisa do Estado de São Paul
