Abnormal liver function in brucellosis
2008
We assessed the prevalence of impaired liver function in 47 patients suffering from brucellosis consecutively admitted to our department over the last five years. Parameters of liver function and ultrasound of the upper abdomen were performed at entry and at the end of treatment. On admission, mean transaminase values were elevated and significantly higher than at recovery (p 0.001): 38 percent and 53 percent of patients had elevated baseline values of GOT and GPT vs 13 and 19% at the end of treatment, respectively. Mean serum values of alkaline phosphatase (AP) were within normal limits on admission, although in 12 of them serum values were elevated. The same proportion was seen for gamma-…
Bioindicators and nutrient availability through whole soil profile under orange groves after long-term different organic fertilizations
2019
We investigated long-term (18 years) effects of three organic (cow manure (CM), poultry manure (PM), compost from agro-industry orange wastes (OW)) and one inorganic fertilization (IF) on various soil biological indicators (microbial biomass C, soil respiration, total phospholipid fatty acids (PLFAs), total bacteria, Gram-positive and Gram-negative bacteria and fungi) and nutrient contents (total and extractable organic C, total and mineral N, available P and K) along the profile of a Typic Haplustept under orange Mediterranean orchards. All fertilizers were added on the same N content basis (190 kg N ha−1 per year). Variables related to carbon cycling gradually worsened with depth, regardl…

Soil microbial biomass responses to essential oils extracted from different Mediterranean herbs
Essential oils (EOs) extracted form herbs contain terpenes, terpenoids and polyphenols which show inhibitory effects on seed germination and seedling growth of weeds. Therefore, EOs are potential sources for the development of new bioherbicides. A previous study carried out by the authors has found EOs extracted from Thymbra capitata (L.) Cav., Mentha x piperita L., and Santolina chamaecyparissus L. were able to reduce the emergence and seedling growth of many weeds. However, due to their potential antimicrobial activity, EOs could affect all soil processes mediated by microorganisms. Since EOs impacts seem to be rather complex as they have been found not only to inhibit but also stimulate …
Comparing different processing methods in apple slice drying. Part 2 solid-state Fast Field Cycling 1H-NMR relaxation properties, shrinkage and chang…
2019
The objective of this paper was to study the effects of different drying methods that are: microwave (MW), hot air (HA) and a combination of both (HY), on the 1H-NMR relaxation properties, shrinkage and volatile compounds of Golden Delicious apple slices. Fast field cycling NMR relaxometry reveals that the HA samples dried at different temperatures (65 and 75 °C) appear to contain less restrained water as compared to the sample obtained by MW heating at the same temperatures. In fact, the longitudinal relaxation rates (T1) of the water molecules in the HA dried slices resulted shorter than those measured for the MW dried samples, thereby revealing that in the MW slices, water molecules beha…
Isolation and characterization of Bartonella quintana from parotid gland of an immunocompetent man.
2009
We describe a case of the isolation of Bartonella quintana from the parotid gland of an apparently healthy man. Pathological examination showed intraparotid granulomatous abscessual lymphadenitis. Diagnosis was made on the basis of high titers of immunoglobulin G (IgG) and IgM antibodies and of culture isolation of a causative agent from parotid aspirate.

Metabolic responses of microbial community in soil amended with fresh leaves and leaf extracts from eucalyptus spp.
Field observations reveal that often large areas of soil surface beneath Eucalyptus occidentalis Endl. are completely bare or with scant vegetation. Moreover, previous studies have showed that other species of Eucalyptus, such as Eucalyptus camaldulensis Dehn, may be effective in suppressing seed germination and weed growth. Such effects have been ascribed to the large number of secondary metabolites within Eucalyptus leaves. Due to their inhibition activity against weeds, leaf extracts might be used for an integrated weed management context, in accordance with the Directive 2009/128/EC. Several studies exist about the effects of Eucalyptus leaf extracts on weeds, whereas they are lacking o…
Regeneration of cellulose by water addition to phosphoric acid/cellulose mixture
2013
In the last years, phosphoric acid has been increasingly considered as a simple and economic solvent for cellulose pretreatment before its degradation to glucose. Cellulose swells in 71–80% phosphoric acid solutions, whereas at higher H3PO4 concentrations dissolution appears to occur. In addition, it is reported that regenerated cellulose is more easily fermentable to bioethanol. The aim of the present study was to elucidate the mechanism for cellulose regeneration following treatment with phosphoric acid at room temperature. CPMAS 13C NMR spectra revealed a downfield shift of the 13C NMR signals from the regenerated cellulose as compared to the crystalline one. CPMAS 31P NMR spectroscopy s…

Interessamento epatico in corso di febbre bottonosa del Mediterraneo
2007
In this study we retrospectively assessed the prevalence of impaired liver function in all 49 patients suffering from Mediterranean Spotted Fever (MSF) consecutively admitted to our department over the last four years. The main parameters of liver function and ultrasound of upper abdomen were performed at entry and at the end of treatment. At admission mean values of transaminases were above the normal limits and significantly higher when compared to mean serum levels at recovery. 55% and 51% of patients had serum values of GOT and GPT, respectively, above the normal limits versus 1% and 2% at the end of treatment. Mean serum values of alkaline phosphatase (AP) were within the normal limits…
PREVALENCE OF ANTIBODIES ANTI-BARTONELLA HENSELAEIN WESTERN SICILY: CHILDREN, BLOOD DONORS, AND CATS
2011
To evaluate seroprevalence of B. henselae infection both in Sicilian children and healthy blood donors. Furthermore, circulation of Bartonella in the natural reservoir was also studied. Two hundred forty-three children, living in Sicily (Palermo), affected by various diseases, without clinical features suggesting B. henselae infection, together with 122 healthy blood donors were serologically investigated for IgG and IgM antibodies by indirect fluorescent antibody test (IFAT). One hundred twenty stray and 62 pet cats were also analyzed only for IgG. Among children 25.1% had IgG antibodies to B. henselae; 18.5% showed a titer 1:64, 2.4% 1:128, 2.4% 1:256, 0.8% 1:512, 0.4% 1:1024, and 0.4% 1:…
Fast field cycling NMR relaxometry as a tool to monitor Parmigiano Reggiano cheese ripening.
2020
Abstract It is widely recognized that the longer the ageing, the more valuable Parmigiano Reggiano (PR) cheese becomes, due to the improvement of its sensorial and nutritional properties. Up to now, the evaluation of PR properties has been performed on samples mainly aged up to 40 months. For this reason, this study was aimed at collecting information about the chemical-physical characteristics of PR cheeses after ageing at 24, 48 and 84 months. The basic analyses on water amount, protein content and volatile organic compounds (VOC) revealed that PR ageing is associated to the decomposition of the organic components into smaller units. This drives water molecules closer to the aforementione…
BIOCHAR SURFACE PROPERTIES THROUGH APPLICATION OF AN INNOVATIVE NMR TECHNIQUE: FAST FIELD CYCLING RELAXOMETRY
2013
Biochar is a carbonaceous material obtained by pyrolysis of biomass feedstocks. It is applied to soils in order to improve fertility and mitigate greenhouse-gases emissions. In fact, from the one hand, biochar changes physical-chemical soil properties, thereby affecting soil fertility. From the other hand, biochar is resistant to chemical and biochemical degradation. For this reason, its use allows carbon sequestration in soils and consequent reduction of carbon dioxide to the atmosphere. Here, dynamics of water at the liquid-solid interface of water saturated biochars is discussed. Results revealed that water dynamics is affected by the nature of biochar parent biomasses. Moreover, biochar…
