[Detection of microorganisms and resistance genes from positive blood cultures using the FilmArray® BCID2 panel: Experience in a pediatric hospital].

The rapid identification of microorganisms that cause bacteremia and their possible resistance markers are extremely important for the timely initiation of effective antibiotic therapy. The FilmArray® panel BCID2 (an automated rapid multiplex PCR assay) detects microorganisms and resistance genes from positive blood cultures within one hour. The aim of this study was to compare the results obtained from the FilmArray® Panel BCID2 and conventional culture in pediatric patients, as well as the reporting times of both methods.

Role of the Drying Technique on the Low-Acyl Gellan Gum Gel Structure: Molecular and Macroscopic Investigations.

The effect of three drying processes (freeze, oven and supercritical CO drying) on CP Kelco low-acyl gellan gum gel was investigated, highlighting the role of the water removal mechanism (i.e. sublimation, evaporation and solvent replacement/extraction) and the process parameters on the gel structure, rather than focusing on the drying kinetics.

Interaction of Mannitol and Sucrose with Gellan Gum in Freeze-Dried Gel Systems.

The effect of sucrose and mannitol addition to low-acyl (LA) gellan gum gels at both the molecular and macroscopic levels prior to, and after freeze-drying has been investigated. It has been shown that the gel network order as well as the mechanical properties are changed with the solute content, especially in the case of sucrose. The freeze-dried gel structure, containing either mannitol or sucrose, was studied, reporting for the first time the interaction of mannitol with the gellan gum gel.

Effect of journey time and environmental condition on bull behaviour and beef quality during road transport in northern Italy.

Response to a transport time of 1 and 3 hours on the road carried out under different environmental conditions was evaluated on 60 pure-breed Charolaise bulls. Temperature and relative humidity from loading to slaughter were expressed as THI (Temperature-Humidity Index). Regardless of journey time or environmental conditions, the most common standing orientation was either perpendicular or parallel to the direction of travel.

Liposoluble vitamins and naturally occurring carotenoids in porphyria cutanea tarda.

The authors consider two groups of patients with overt sporadic porphyria cutanea tarda (PCT) from different continents, with the aim of evaluating the possible impairment of the liposoluble antioxidative system, given the possible synergic effect of porphyrins and iron in promoting oxidative cellular damage. Twenty-three Italian outpatients with overt sporadic PCT and 11 outpatients with PCT from Buenos Aires (Argentina) were matched with 60 patients with liver cirrhosis and 52 healthy Italian controls. Serum levels of alpha- and beta-carotene, cryptoxanthin, zeaxanthin, lutein, lycopene, retinol and alpha-tocopherol were detected by a high-performance liquid chromatographic technique devised in our laboratory, which afforded an accurate and simultaneous resolution of all these compounds.
