Objective: To determine the exposure of wild brown hares [Lepus europaeus(L. europaeus), pallas] to Anaplasma phagocytophilum(A. phagocytophilum), Borrelia burgdorferi(B. burgdorferi) sensu lato, Encephalitozoon cuniculi(E. cuniculi), Leishmania sp., Neospora caninum(N. caninum) and Toxoplasma gondii(T. gondii). Methods: Two hundred twentytwo blood serum samples of wild brown hares captured in protected areas of the province of Pisa(Central Italy) were tested to detect antibodies against the reported pathogens. Results: Thirty one(14.0%) animals resulted positive for at least one tested agent, with antibody titres ranging from 1:20 to 1:320. In particular, 13(5.8%) samples were positive to B. burgdorferis.l., 11(4.9%) to N. caninum, 3(1.3%) to T. gondii, 2(0.9%) to A. phagocytophilum and 2(0.9%) to Leishmania sp. No samples scored positive to E. cuniculi. Four animals(14.8%) resulted coinfected with 2 different pathogens. Conclusion: The obtained results showed that B. burgdorferi s.l. N. caninum, T. gondii, A. phagocytophilum and Leishmania sp circulate in wild brown hares in Central Italy, suggesting a possible role of L. europaeus as reservoir of these pathogens. The obtained results showed that autochthonous wild brown hares living in Central Italy have been exposed to several pathogens circulating in this area, suggesting a possible role of L. europaeus as reservoir.

The rationale of the performance of anatomic resection(AR)of the liver in case of hepatocellular carcinoma(HCC)is the removal of portal pedicle feeding the tumor because of the tumor’s tendency to invade the portal veins(1).This technical approach is expected to be effective from an oncological perspective for a disease such as HCC,which is associated with a high rate of intrahepatic recurrence(2,3).In the eighties,Makuuchi et *** the systematic subsegmentectomy(4)reporting excellent results(5),and later some other authors reported new techniques to identify the portal territory of a given HCC and perform a true AR of the liver(5-7).

Intraoperative ultrasonography(IOUS)in hepatobiliary surgery is well known as an essential tool for radical and safe hepatectomies,allowing to perform parenchymal sparing surgery and,as consequence,to expand the surgical indications for patients otherwise considered ***,since many years,despite its effectiveness in the study of vascular anatomy of the liver,the gold standard for the assessment of biliary anatomy during surgery is intraoperative cholangiography(IOC),which is used for the validation of preoperative imaging as well as for guiding reconstruction in case of bile duct injury or resection.

Leadership courses in the fire services are highly challenging, and they can seriously exhaust trainees and hamper their selfregulated learning efforts(for example, setting goals, focusing attention, seeking feedback). We theorize that experiences of failure or overload can curtail trainees' available energy resources on subsequent training days, which, in turn, should affect trainees' learning efforts. Given instructors' central role in leadership courses, we hypothesize that supportive and humble instructor behaviors decrease experiences of failure and overload and, thus, increase self-regulated learning. Moreover, we argue that supportive instructor behavior may amplify the positive effects of high energy resources, while humble behavior may alleviate the negative impact of low resource levels. We tested preregistered hypotheses with 118 firefighters participating in two-week leadership courses at a German fire academy. The participants completed short web-based questionnaires before and after classes each day. Multilevel analyses confirmed that perceived daily supportive and humble instructor behavior predicted trainees' reports of daily self-regulated learning activity. Notably, this effect was independent from positive effects of trainees' reported energy resources in the morning. Supportive and humble behavior did not moderate the eff ect of energy resources. Our findings suggest that instructors play a crucial role in facilitating effective learning under challenging training conditions. Furthermore, we offer implications for leaders in fire services, who often conduct trainings with their subordinates.

This paper shows a didactic model (PGM), and not only, but representative of the Hadrons described in the Standard Model (SM). In this model, particles are represented by structures corresponding to geometric shapes of coupled quantum oscillators (IQuO). By the properties of IQuO one can define the electric charge and that of color of quarks. Showing the “aurea” (golden) triangular shape of all quarks, we manage to represent the geometric combinations of the nucleons, light mesons, and K-mesons. By the geometric shape of W-bosons, we represent the weak decay of pions and charged Kaons and neutral, highlighting in geometric terms the possibilities of decay in two and three pions of neutral Kaon and the transition to anti-Kaon. In conclusion, from this didactic representation, an in-depth and exhaustive phenomenology of hadrons emerges, which even manages to resolve some problematic aspects of the SM.
