Immunoaffinity purification and characterization of mitochondrial membrane-bound D-3-hydroxybutyrate dehydrogenase from Jaculus orientalis.
2008
Abstract Background The interconversion of two important energy metabolites, 3-hydroxybutyrate and acetoacetate (the major ketone bodies), is catalyzed by D-3-hydroxybutyrate dehydrogenase (BDH1: EC 1.1.1.30), a NAD+-dependent enzyme. The eukaryotic enzyme is bound to the mitochondrial inner membrane and harbors a unique lecithin-dependent activity. Here, we report an advanced purification method of the mammalian BDH applied to the liver enzyme from jerboa (Jaculus orientalis), a hibernating rodent adapted to extreme diet and environmental conditions. Results Purifying BDH from jerboa liver overcomes its low specific activity in mitochondria for further biochemical characterization of the e…

Risk of Bacillus cereus and Pseudomonas aeruginosa nosocomial infections in a Burns Centre: the microbiological monitoring of water supplies for a pr…
1995
This paper reports on an extensive epidemiological survey of the microbiological monitoring of the environment, staff, and patients in the Intensive Care Unit of the Palermo Bums Centre (Italy). The aim of the survey was to evaluate the presence and distribution of environmental sources of pathogens and opportunistic bacterial agents of nosocomial infection in immunocompromised hosts. Strains collected from air, tap water, and medical and nursing staff were compared with strains isolated from burn patients in order to study the potential transmission route of bacteria. The results showed environmental strains presenting a profile identical to that of the clinical strains, suggesting a link …
Intervención nutricional en niños y adolescentes con fibrosis quística. Relación con la función pulmonar
2005
Cecilia.Martinez@uv.es; Francisco.Nunez@uv.es; Objetivo: Evaluar los efectos de la intervención nutricional precoz y continuada en pacientes pediátricos con fibrosis quística (FQ) y su posible implicación en la función pulmonar. Pacientes y métodos: Se incluyen el seguimiento de 19 pacientes con FQ (11 niñas, 8 niños) de 17 meses a 18 años de edad y promedio de 10 años de enfermedad. El genotipo de 16 pacientes es delta F 508 (10 homo, 6 heterocigotos). Cada 2-3 meses se les ha realizado: valoración clínica, dietética y antropométrica clasificando el estado de nutrición (EN) según Z pesto/talla, % peso para la talla, índice de masa corporal y Z talla/edad. Coincidentemente se obtuvo cultivo…
A novel VIM‐type metallo‐beta‐lactamase (VIM‐14) in a Pseudomonas aeruginosa clinical isolate from a neonatal intensive care unit
2011
AbstractA Pseudomonas aeruginosa highly resistant to carbapenems was isolated in a neonatal intensive care unit in Palermo, Italy. The strain was found to carry a novel VIM‐type enzyme, classified as VIM‐14. The novel enzyme differs from VIM‐4 in a G31S mutation. VIM‐14 was harboured in a class 1 integron with a new organization. The integron carried the genes aac7, blaVIM‐14, blaOXA‐20 and aac4 in that order.
Uso del tonometro e rischio infettivo ; valutazione dell'efficacia di differenziali tipi di disinfettanti.
2006
Obiettivo: valutare e confrontare l’efficacia dei più comuni tipi di disinfettanti per la disinfezione dei coni tonometrici e trarre alcune indicazioni sulla applicabilità alla realtà clinico-diagnostica in campo oftalmologico. Materiali e metodi: coni tonometrici monouso sterili, previamente contaminati con ceppi standard di Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa e Candida albicans sono stati testati, dopo semplice detersione o disinfezione con acqua ossigenata al 3%, benzalconio cloruro allo 0.5%, Minuten wipes (Alpro® ), Pantasept® allo 0.5% secondo le linee guida del CDC di Atlanta. Risultati: la semplice detersione è stata inefficace contro tutte le specie tes…
Drug resistance patterns of bacteria isolated from patients with nosocomial pneumonia at Tehran hospitals during 2009-2011
2013
Introduction: Nosocomial pneumonia remains an important cause of mortality and morbidity worldwide. Surveillance programs play an important role in the identification of common etiologic agents and local patterns of antimicrobial resistance. Methodology: In this study we determined the frequency and antimicrobial susceptibility of pathogens isolated from patients with nosocomial pneumonia during 2009 to 2011. Results: A total of 642 bacteria were isolated from 516 suspected samples. Acinetobacter baumannii (21.1%, n = 136), was the commonest isolated pathogen followed by Pseudomonas aeruginosa (17.4%, n = 112) , Staphylococcus aureus (15.8%, n = 102) and enterococci (8.4% n = 54).
