The spiny spider crab Maja goltziana (Crustacea: Majidae) in the south Lebanese waters.

A total of 52 specimens (45–115 mm carapace length) of Maja goltziana d’Oliveira 1888, was collected along the Lebanese coasts (south-eastern Mediterranean Sea) in 2006–2007. This species, till now considered rare in the Mediterranean Sea, is common and abundant along the deep shelf-upper Lebanese coast where a local population is present

Optimal Operations Management of Hybrid Energy Systems Through Short-Term Atmospheric and Demand Forecasts

Abstract The complexity of systems for energy production through renewable energy sources (RESs) is constantly increasing considering the integration of multiple modules, e.g. different RES sources, energy storage in batteries and connection to national grid for energy trade purpose. This significant complexity could represent a threat but also an opportunity if adequately managed. Aim of this paper is to propose two different approaches to manage the hourly electricity flows between the different components of a hybrid energy system (HES) fueled by PV modules and a wind turbine, equipped with a battery storage system (BES) to satisfy the demand of a user load with the opportunity to sell and purchase the electricity to/from the national grid. The first approach is a heuristic algorithm (HA) which defines robust but constant dispatching criteria of the energy flows between the HES components considering just the current value of energy production and demand with the aim of minimizing the electricity purchased by the grid. On the contrary, the second approach is a mixed integer linear programing (MILP) model which defines the optimal value of the energy flows to maximize the net profit of the HES operations determined by the electricity sales revenues minus the energy purchase costs. The developed MILP leverages the short-term forecast of the atmospheric conditions and user demand as well it considers variable energy sale and purchase pricing in the different daily hours. Both these approaches have been tested and validated through a case study of a residential building in which multiple households live located in the suburban area of Munich (Germany). The obtained results highlight how the MILP outperforms HA considering the net profit achievable weekly due to electricity trade with the grid. In particular, the MILP improve the HA economic performance of the HES operation management of 18% on average over the different months of the year

An allosteric cross-talk between the activation loop and the ATP binding site regulates the activation of Src kinase

Phosphorylation of the activation loop is a fundamental step in the activation of most protein kinases. In the case of the Src tyrosine kinase, a prototypical kinase due to its role in cancer and its historic importance, phosphorylation of tyrosine 416 in the activation loop is known to rigidify the structure and contribute to the switch from the inactive to a fully active form. However, whether or not phosphorylation is able per-se to induce a fully active conformation, that efficiently binds ATP and phosphorylates the substrate, is less clear. Here we employ a combination of solution NMR and enhanced-sampling molecular dynamics simulations to fully map the effects of phosphorylation and ATP/ADP cofactor loading on the conformational landscape of Src tyrosine kinase. We find that both phosphorylation and cofactor binding are needed to induce a fully active conformation. What is more, we find a complex interplay between the A-loop and the hinge motion where the phosphorylation of the activation-loop has a significant allosteric effect on the dynamics of the C-lobe

Rise of pediatric robotic surgery in Italy: a multicenter observational retrospective study

open15noAbstract Background: The minimally invasive surgery (MIS) in term of robot-assisted surgery changed in a dramatic way the surgical approach either in adults or children. For many specialties (urology, gynecology, general surgery) robotic surgery rapidly became the gold standard for some procedures, while the experience in pediatric population is not wide for some reasons. The aim of this study is to retrospective analyze trends of application of robotic surgery in pediatric patients across the country, focusing on indications, limitations, development, and training acquired by national experience and in comparison to the literature. Methods: We made a retrospective multicenter study on behalf of Italian Society of Pediatric Surgery. We performed a census among all pediatric surgery units in the country to enroll those performing robotic surgery on children between 2013 and 2019. Results: We enrolled 7 pediatric surgery referral Centers (Ancona, Bologna, Brescia, Genova, Pavia, Pescara, Siena). A total of 303 patients were included in the study, 164 males (54%) and 139 females (46%). The most commonly performed interventions for each anatomic area were respectively atypical pulmonary resection (38%), pyeloplasty (49%), and fundoplication (30%). Conclusions: Since its first application in Italy, about 10 years ago, several considerations were made about application and feasibility of robotics in children.openAngotti, Rossella; Raffaele, Alessandro; Molinaro, Francesco; Riccipetitoni, Giovanna; Chiesa, Pierluigi Lelli; Lisi, Gabriele; Mattioli, Girolamo; Alberti, Daniele; Boroni, Giovanni; Mariscoli, Francesca; Martino, Ascanio; Pelizzo, Gloria; Maffi, Michela; Messina, Mario; Lima, MarioAngotti, Rossella; Raffaele, Alessandro; Molinaro, Francesco; Riccipetitoni, Giovanna; Chiesa, Pierluigi Lelli; Lisi, Gabriele; Mattioli, Girolamo; Alberti, Daniele; Boroni, Giovanni; Mariscoli, Francesca; Martino, Ascanio; Pelizzo, Gloria; Maffi, Michela; Messina, Mario; Lima, Mari

West Nile virus transmission. results from the integrated surveillance system in Italy, 2008 to 2015

IIn Italy a national Plan for the surveillance of imported and autochthonous human vector-borne diseases (chikungunya, dengue, Zika virus disease and West Nile virus (WNV) disease) that integrates human and veterinary (animals and vectors) surveillance, is issued and revised annually according with the observed epidemiological changes. Here we describe results of the WNV integrated veterinary and human surveillance systems in Italy from 2008 to 2015. A real time data exchange protocol is in place between the surveillance systems to rapidly identify occurrence of human and animal cases and to define and update the map of affected areas i.e. provinces during the vector activity period from June to October. WNV continues to cause severe illnesses in Italy during every transmission season, albeit cases are sporadic and the epidemiology varies by virus lineage and geographic area. The integration of surveillance activities and a multidisciplinary approach made it possible and have been fundamental in supporting implementation of and/or strengthening preventive measures aimed at reducing the risk of transmission of WNV trough blood, tissues and organ donation and to implementing further measures for vector control

Evidence of Simultaneous Circulation of West Nile and Usutu Viruses in Mosquitoes Sampled in Emilia-Romagna Region (Italy) in 2009

BACKGROUND: In recent years human diseases due to mosquito-borne viruses were increasingly reported in Emilia-Romagna region (Italy), from the chikungunya virus in 2007 to the West Nile virus (WNV) in 2008. An extensive entomological survey was performed in 2009 to establish the presence and distribution of mosquito arboviruses in this region, with particular reference to flaviviruses. METHODOLOGY/PRINCIPAL FINDINGS: From May 6 to October 31, a total of 190,516 mosquitoes were sampled in georeferenced stations, grouped in 1,789 pools according date of collection, location, and species, and analyzed by reverse transcription polymerase chain reaction (RT-PCR) to detect the presence of RNA belong to Flavivirus genus. WNV was detected in 27 mosquito pools, producing sequences similar to those of birds and human strains obtained in 2008 outbreak, pointed out the probable virus overwintering. Isolation of WNV was achieved from one of these pools. Moreover 56 pools of mosquitoes tested positive for Usutu virus (USUV). Most PCR positive pools consisted of Culex pipiens, which also was the most analyzed mosquito species (81.4% of specimens); interestingly, USUV RNA was also found in two Aedes albopictus mosquito pools. Simultaneous circulation of WNV and USUV in the survey area was highlighted by occurrence of 8 mosquito WNV- and USUV-positive pools and by the overlaying of the viruses "hot spots", obtained by kernel density estimation (KDE) analysis. Land use of sampled stations pointed out a higher proportion of WNV-positive Cx. pipiens pool in rural environments respect the provenience of total sampled pool, while the USUV-positive pools were uniformly captured in the different environments. CONCLUSIONS/SIGNIFICANCE: Obtained data highlighting the possible role of Cx. pipiens mosquito as the main vector for WNV and USUV in Northern Italy, and the possible involvement of Ae. albopictus mosquito in USUV cycle. The described mosquito-based surveillance could constitute the foundation for a public health alert system targeting mosquito borne arboviruses
