Microglia and α-synuclein implication in Parkinson's disease
2011
Age-related neurodegenerative disorders like Parkinson’s disease take an enormous toll on individuals and on society. Despite extensive efforts, Parkinson’s disease remains incurable and only very limited treatments exist. Indeed, Parkinson’s pathogenesis is still not clear and research on its molecular mechanisms is ongoing. In this study, we focused our interest on two abnormal events occurring in Parkinson’s patients, namely α-synuclein aggregation and microglial activation. We first investigated α-synuclein and its abnormal polymerisation. For this purpose, we developed novel methods, which allowed the in vitro production of different types of α-synuclein oligomers. Using highly sensiti…

(Un)framing Lampedusa: Regimes of Visibility and the Politics of Affect in Italian Media Representations
2017
The 3rd of October 2013 more than 300 migrants died after a boat sank off the coasts of Lampedusa. This probably was the most dramatic shipwreck ever happened in the Mediterranean, and certainly the one which attracted the most media attention in Italy and elsewhere. Since at least 1992 the Mediterranean has become the unstable ground where the dominant policies of regulated mobility and discontinuous surveillance are continuously challenged by bodies which struggle for their fundamental right to move. This conflict between global regimes of disciplined mobility (Philo 2014) and singular forms of embodied resistance (Agamben 1990) involves also the field of representation and its forcible e…
On the Impact of Heat Pumps Electric Load on the Power Consumption of Lampedusa
2020
The present paper reports the results of a simulation study regarding the impact of the adoption of heat pumps for domestic hot water production in the island of Lampedusa (Italy). In the study, it has been assumed to replace electric storage water heaters with heat pumps at every dwelling of the about four thousand domestic end-users of the island and, in addition, to control the heat pump operation in order to enhance some parameters that characterize the quality of the generation and distribution system of the island (power peak, energy losses and voltage drop). According to the results of the simulations, while the replacement of electric storage water heaters with heat pumps is able to…
Geochemistry, Sr–Nd–Pb isotopes and geochronology of amphibole- and mica-bearing lamprophyres in northwestern Iran: Implications for mantle wedge het…
2015
Highlights • Northwestern Iranian lamprophyres have alkaline and calc-alkaline nature. • Studied lamprophyres are emplaced during Late Cretaceous to Late Miocene time. • Lamprophyres originated from different metasomatised lithospheric mantle. Abstract Lamprophyres of different age showing distinctive mineralogy, geochemistry and isotopic ratios are exposed in northwestern Iran. They can be divided into Late Cretaceous sannaite, Late Oligocene-Early Miocene camptonite (amphibole-bearing) and Late Miocene minette (mica-bearing) and spessartite (amphibole-bearing) lamprophyres. Sannaites have high-Ti amphibole along with high-Ti and Al clinopyroxene, and they are characterised by homogeneous …
Long-Term Potentiation in the Neonatal Rat Barrel Cortex In Vivo
2012
Long-term potentiation (LTP) is important for the activity-dependent formation of early cortical circuits. In the neonatal rodent barrel cortex, LTP has been studied only in vitro . We combined voltage-sensitive dye imaging with extracellular multielectrode recordings to study whisker stimulation-induced LTP in the whisker-to-barrel cortex pathway of the neonatal rat barrel cortex in vivo . Single whisker stimulation at 2 Hz for 10 min induced an age-dependent expression of LTP in postnatal day (P) 0 to P14 rats, with the strongest expression of LTP at P3–P5. The magnitude of LTP was largest in the activated barrel-related column, smaller in the surrounding septal region, and no LTP could b…
A longitudinal study of C1q and anti-C1q autoantibodies in homologous and heterologous pregnancies for predicting pre-eclampsia
2022
C1q, the recognition molecule of the classical pathway of the complement system, plays a central role in pregnancy. Lack of C1q is characterized by poor trophoblast invasion and pregnancy failure. C1q can be the target of an antibody response: anti‐C1q autoantibodies (anti-C1q) are present in several infectious and autoimmune diseases. The presence of these autoantibodies has been detected also in 2-8% of the general population. Recent evidence indicates that women who undergo assisted reproductive technology (ART) have an increased risk of developing pre-eclampsia (PE), particularly oocyte donation (OD) pregnancies. The aim of this study was to characterize the levels of C1q and anti-C1q i…
A clampless and sutureless aortic anastomosis technique using an endograft connector for aortoiliac occlusive disease in which the aorta cannot be cl…
2012
Bypass surgery in aortoiliac or aortofemoral occlusive disease can be technically demanding and hazardous due to huge calcifications and/or patient co-morbidities. We report about mid-term results of a telescoping sutureless aortic anastomosis technique using endografts as connectors to address such challenging situations. This is a single-center experience (2004–2011) in seven patients (63 ± 6 years) requiring aortoiliac (three) or aortofemoral (four) bypass surgery. In six cases, an aortic stent graft was telescoped into the infrarenal aorta and partly deployed within the aorta and partly outside the aorta. In the first case, a bifurcated stent graft was deployed and the iliac legs were p…

Arsēnu un dzīvsudrabu saturošu gaismas avotu spektrālie mērījumi UV reģionā
2022
Darbā pētītas arsēnu un dzīvsudrabu saturošu gaismas avotu spektroskopiskās īpašības ultravioletajā reģionā. Tika apskatītas augstfrekvences bezelektrodu un dobjā katoda lampas, kas tiek izmantotas atomu absorbcijas spektroskopijā. Darbā tika mērītas šo lampu starojuma intensitātes relatīvajās un absolūtajās vienībās atkarībā no ģeneratora jaudas. Tika uzņemta spektrāllīniju intensitāšu stabilitāte laikā. No datu analīzes tika secināts, ka, palielinot jaudu, līniju intensitātes palielinās ek- sponenciāli. Darbam atomu absorbcijas spektroskopijai piemērotākas ir augstfrekvences bezelektrodu lampas, jo tām ir intensīvāks starojums. Abu veidu lampas ir laikā stabilas, bet augstfrekvences bezel…
