The Serological Diagnosis of Canine Leishmaniasis: Commercial ELISA or in House IFAT?  [PDF]
Pasquale Santoro, Andrea Vellusi
Open Journal of Veterinary Medicine (OJVM) , 2015, DOI: 10.4236/ojvm.2015.52005
Abstract: The levels of anti-Leishmania infantum antibodies are relevant with the diagnosis and the followup of infected dogs. Both ELISA (Enzyme-Linked Immunosorbent Assay) and IFAT (Indirect Immuno-Fluorescent Antibody Test) may be employed to estimate the antibody levels in dogs, but at present, the correlation between ELISA absorbance and IFAT titer has not been investigated. In this paper, we compared the optical densities obtained with a commercial ELISA, Leiscan?(Laboratorios Dr. Esteve S.A.), versus the titers obtained by in house IFAT. We measured ELISA absorbance of: 44 IFAT negative samples coming from an endemic area; 10 negative samples coming from a non endemic area; 29 samples with an IFAT titer between 1/40 and 1/80; 10 samples with an IFAT titer of 1/160; 9 samples with an IFAT titer of 1/320; 10 samples with an IFAT titer of 1/640; 10 samples with an IFAT titer ≥ of 1/1280. Results show that: a) there is a poor correlation between IFAT titer and ELISA absorbance; b) Leiscan? is not able to distinguish between IFAT negative samples and IFAT titers up to 1:160; c) IFAT negative samples from an endemic or non endemic area show different ELISA absorbance; d) the performance of the kit may be improved by the use of a more appropriate cut-off.
Different Patterns of Fluorescence in the Quantisation of anti-Leishmania Infantum Antibodies by Indirect Immuno-Fluorescent Antibody Test (IFAT) in the Serological Diagnosis of Canine Leishmaniasis  [PDF]
Pasquale Santoro, Andrea Vellusi
Open Journal of Veterinary Medicine (OJVM) , 2017, DOI: 10.4236/ojvm.2017.73003
Abstract: Although Indirect Immuno-Fluorescent Antibody Test (IFAT), performed employing “in house” prepared antigen, is considered by several authors as the golden standard for the quantisation of anti-leishmania antibodies in dogs, there is a lack of papers reporting a description of the different patterns of fluorescence that can be observed. An incorrect identification of patterns of fluorescence may be an important source of bias in the interpretation of results. Previous papers report different criteria to define as “positive” a specific pattern of fluorescence, namely: membrane fluorescence, homogeneous fluorescence of the body, or homogeneous fluorescence of the body plus flagellum. In this paper, we report a detailed description of preparation of slides and of the patterns of fluorescence that can be obtained employing “in house” prepared antigen. At least six main patterns of fluorescence may be observed: 1): homogeneous cytoplasmatic green fluorescence; 2): membrane pattern, in which the fluorescence is mainly localized along the entire perimeter of the parasites; 3): coarse-speckled cytoplasmatic fluorescence; 4): flagellar pattern, in which the fluorescence is localized exclusively onto the flagellum; 5): punctiform pattern, in which the fluorescence is localized exclusively at the basis of the flagellum; 6): nuclear pattern, in which only the nucleus of the parasite shows a homogeneous green fluorescent. The significance of each pattern is discussed.
Cereal-forage crop rotations and irrigation treatment effect on water use efficiency and crops sustainability in Mediterranean environment  [PDF]
Pasquale Martiniello
Agricultural Sciences (AS) , 2012, DOI: 10.4236/as.2012.31007
Abstract: Agricultural systems based on crop rotations favour sustainability of cultivation and productivity of the crops. Wheat-forage crops rotations (annual winter binary mixture and perennial alfalfa meadow) combined with irrigation are the agronomical techniques able to better exploit the weather resources in Mediterranean environments. The experiment aimed to study the effect of 18 years of combined effect of irrigation and continuous durum wheat and wheat-forage rotations on productivities of crops and organic matter of topsoil. The experiments were established through 1991-2008 under rainfed and irrigated treatments and emphasized on the effect of irrigation and continuous wheat and wheat-forage crop rotations on water use efficiency and sustainability of organic matter. The effect of irrigation increased 49.1% and 66.9% the dry matter of mixture and meadow, respectively. Continuous wheat rotation reduced seed yield, stability of production, crude protein characteristics of kernel and soil organic matter. The yearly gain in wheat after forage crops was 0.04 t (ha·yr)-1 under rainfed and 0.07 t (ha·yr)-1 under irrigation treatments. The crude protein and soil organic matter of wheat rotations, compared to those of continuous wheat under rainfed and irrigated was increase in term of point percentage by 0.8 and 0.5 in crude protein and 5.1 and 4.4 in organic matter, respectively. The rotations of mixture and meadow under both irrigated treatments increased the point of percentage of organic matter over continuous wheat (9.3.and 8.5 in mixture and 12.5 and 9.5 meadow under rainfed and irrigation, respectively). Irrigation reduce the impact of weather on crop growing reducing water use efficiency (mean over rotations) for dry mater production (15.5 in meadow and 17.5 in mixture [L water (kg·dry·matter)-1 ]) and wheat seed yield. The effect of agronomic advantages achieved by forage crops in topsoil expire its effect after three years of continuous wheat rotation.
Securitizing Area Insurance: A Risk Management Approach  [PDF]
Pasquale Lucio Scandizzo
Journal of Financial Risk Management (JFRM) , 2013, DOI: 10.4236/jfrm.2013.23009
Abstract: This paper examines the possibility of developing a risk management instrument by designing a financial security whose value is linked to the average revenue of a given area. This type of program is sufficiently general to be considered for any group of businesses that face production uncertainty. In agriculture, it has been proposed as an alternative to multiple peril crop insurance programs, as area yield, revenue or rainfall insurance in order to eliminate ex ante and ex post moral hazard. While most of the literature concentrates on the determination of value of the indemnity and the payment of such an insurance, this paper focuses on the fact that, unlike other forms of insurance, area insurance can be cast in the form of a hedging security and, as a consequence, rather than depending only on the demand for diversification (the beta of the Capital Asset Price Model), it makes possible a risk shifting strategy based on the heterogeneity of risk attitudes of the economic agents operating in a given area.

The Recovered Treasure. The Inventory of the Property of Sicilian queens confiscated by Manfredi Alagona in 1393
Santoro, Daniela
Anuario de Estudios Medievales , 2007,
Abstract: Beginning from the discovery, in the “Archivio di Stato” of Palermo, of an inventory containing the belongings confiscated from Manfredi Alagona in 1393, this work reconstructs the story of the treasure of the Sicilian queens (Costanza of Aragon and Maria of Sicily), that had been confiscated from the powerful Alagona family, originally from Aragon, who moved to Sicily. A detailed study of the inventoried movables allows the analysis of several aspects connected to customs and society at the end of the XIVth century, from clothing to utensils, from taste and fashion to care of appearance, from the love of jewels to the workship of relics. Partendo dal ritrovamento, presso l’Archivio di Stato di Palermo, di un inventario di beni confiscati a Manfredi Alagona nel 1393, il lavoro ricostruisce il percorso del tesoro delle regine siciliane (Costanza d’Aragona, Maria di Sicilia) che era stato incamerato dagli Alagona, potente famiglia di origine aragonese trapiantata in Sicilia. Uno studio dettagliato degli oggetti inventariati permette l’analisi di vari aspetti legati al costume e alla società sul finire del XIV secolo, dall’abbigliamento alla tavola, dal gusto e la moda del tempo alla cura della persona, dalla passione per i gioielli al culto per le reliquie.
