Nitrous oxide emission budgets and land-use-driven hotspots for organic soils in Europe
2014
Organic soils are a main source of direct emissions of nitrous oxide (N2O), an important greenhouse gas (GHG). Observed N2O emissions from organic soils are highly variable in space and time, which causes high uncertainties in national emission inventories. Those uncertainties could be reduced when relating the upscaling process to a priori-identified key drivers by using available N2O observations from plot scale in empirical approaches. We used the empirical fuzzy modelling approach MODE to identify main drivers for N2O and utilize them to predict the spatial emission pattern of European organic soils. We conducted a meta-study with a total amount of 659 annual N2O measurements, which was…

La nutrizione proteico/aminoacidica gold standard nel trattamento dell’obesità e del sovrappeso in soggetti con alterazioni endocrino-metaboliche

Low effective population sizes and limited connectivity inxerothermic beetles: implications for the conservation ofan endangered habita
2014
Fragmentation and isolation may have detrimental effects on the viability of populations. Xerothermic grasslands, which are extra-zonal analogues of steppes, are among Europe's most endangered natural environments. Information about connectivity between the remaining habitat patches is critical for effective conservation planning. However, very little is known about the actual levels of isolation of individual xerothermic patches at the inter-regional and local scale. In this study, 16 microsatellite loci were used to investigate genetic diversity, structuring, effective sizes (Ne), and connectivity among populations of the weevil Centricnemus leucogrammus at various geographic scales. Anal…
Biologically based models of cancer risk in radiation research
2020
PURPOSE: In radiation risk analysis the state-of-the-art approach is based on descriptive models which link excess rates of cancer incidence and mortality to radiation exposure by statistical association. To estimate the number of sporadic and radiation-induced cases descriptive models apply parametric dose response function which directly determine the radiation risk. In biologically-based models of cancer risk (BBCR models) dose responses are implemented for key events on the biological level such as early mutations or clonal expansion of initiated cells. Influenced by radiation these events then shape the risk response on the epidemiological level. Although BBCR models facilitate a more …
Impact of granulocyte colony‐stimulating factor on FOLFIRINOX‐induced neutropenia prevention: A population pharmacokinetic/pharmacodynamic approach
2020
Aims Granulocyte colony-stimulating factor (G-CSF) is frequently prescribed to prevent chemotherapy-induced neutropenia, but the administration schedule remains empirical in case of bimonthly chemotherapy such as FOLFIRINOX regimen. This pharmacokinetic/pharmacodynamic (PK/PD) study was performed to determine the effect of different G-CSF regimens on the incidence and duration of neutropenia following FOLFIRINOX administration in order to propose an optimal G-CSF dosing schedule. Methods A population PK/PD model was developed to describe individual neutrophil time course from absolute neutrophil counts (ANC) obtained in 40 advanced cancer patients receiving FOLFIRINOX regimen. The structura…
G-CSF (filgrastim) treatment for amyotrophic lateral sclerosis: protocol for a phase II randomised, double-blind, placebo-controlled, parallel group,…
2020
IntroductionAmyotrophic lateral sclerosis (ALS) is a fatal progressive neurological disorder characterised by a selective degeneration of motor neurons (MNs). Stem cell transplantation is considered as a promising strategy in neurological disorders therapy and the possibility of inducing bone marrow cells (BMCs) to circulate in the peripheral blood is suggested to investigate stem cells migration in degenerated ALS nerve tissues where potentially repair MN damage. Granulocyte-colony stimulating factor (G-CSF) is a growth factor which stimulates haematopoietic progenitor cells, mobilises BMCs into injured brain and it is itself a neurotrophic factor for MN. G-CSF safety in humans has been de…
Sdoppiamento del nome e sdoppiamento della lingua: il destino fallace di un personaggio grassiano.
2012
La protagonista del romanzo Disìo (2005) di Silvana Grasso tenta una metamorfosi impossibile attraverso un cambiamento dei propri dati anagrafici. Memi/Ciane, tra l’essere e il non voler più essere, tra il sud e il nord, tra la debolezza e il coraggio, tra irrazionalità e scienza, modifica anche i propri usi linguistici, adattandoli alla nuova personalità. Il tema del doppio – incarnato dalla doppia identità antroponimica – diventa, in questo romanzo, una modalità di risoluzione personale del proprio io ferito che però non mira alla conciliazione tra le due identità, ma alla soppressione della prima. Come nel caso di Mattia Pascal/Adriano Meis, anche lei, però, dovrà fronteggiare un destino…
Influencia del procesado industrial sobre las características químico-físicas y contenido en lípidos y antioxidantes del salvado de arroz
2009
Se investigaron las características químico-físicas de los salvados de arroz en distintos momentos de su procesado industrial, incluyendo materia prima (salvados de arroz blanco y vaporizado), salvado peletizado y salvado desgrasado. Se determinó la humedad, la acidez y el índice de peróxidos. Utilizando extractos en éter de petróleo y cromatografía de gases, se estableció el contenido lipídico total y los perfiles de los ácidos grasos. Mediante HPLC se determinaron los tocoferoles y el γ-orizanol. El salvado de arroz vaporizado mostró la mayor concentración de lípidos y la menor acidez, lo que indica que el vaporizado es el proceso más eficaz para estabilizar el salvado. Los ácidos oleico,…
Graffiti dello Steri di Palermo e conoscenze mediche
2007
The graffiti left by prisoners in the Inquisition gaols of Palermo's represent a testimony of the historical period between 1600 to 1793. In that period, by order of the viceroy Caracciolo, all the testimonies were removed at the same time in which the Inquisition court was suppressed. In this work the historical subdivision between sacred and profane themes is analyzed with the purpose to study human body in an anthropological key as a language in condition of limited freedom and under torture. Many of the profane graffiti are devoted to medical knowledge suggesting that doctors were involved in the activities of this religious court likewise happened in civil courts. Giovanni Filippo Ingr…
