Yeasts vectored by migratory birds collected in the Mediterranean island of Ustica and description of Phaffomyces usticensis f.a. sp. nov., a new spe…

2014

Nine yeast species belonging to genera Candida , Cryptococcus , Phaffomyces , Rhodotorula and Wickerhamomyces , and one species of Aureobasidium genus were isolated from the cloaca of migratory birds. Candida glabrata and C. inconspicua were the species most frequently isolated and Wickerhamomyces sylviae , which has recently been described as a new species isolated from bird cloaca, was again found. The majority of isolates showed the ability to grow up to 40 °C and/or at pH 3.0, two environmental conditions typical of the digestive tract of birds. The phylogenetic analysis of the D1/D2 domain of 26S rRNA gene placed the cultures of Phaffomyces in a new lineage that differed from the close…

Genome-wide Association Study and Meta-Analysis Identify ISL1 as Genome-wide Significant Susceptibility Gene for Bladder Exstrophy

2015

The bladder exstrophy-epispadias complex (BEEC) represents the severe end of the uro-rectal malformation spectrum, and is thought to result from aberrant embryonic morphogenesis of the cloacal membrane and the urorectal septum. The most common form of BEEC is isolated classic bladder exstrophy (CBE). To identify susceptibility loci for CBE, we performed a genome-wide association study (GWAS) of 110 CBE patients and 1,177 controls of European origin. Here, an association was found with a region of approximately 220kb on chromosome 5q11.1. This region harbors the ISL1 (ISL LIM homeobox 1) gene. Multiple markers in this region showed evidence for association with CBE, including 84 markers with…

Colorectal Cancer in Elderly Patients: From Best Supportive Care to Cure

2013

Colorectal cancer is one of the major causes of cancer mortality in the elderly population (median age at diagnosis of 71 years) in Western Countries. Moreover patients with metastatic disease are often elderly with significant co- morbidities. Unfortunately, elderly patients are often untreated and under-represented in clinical trials, even if most clinical trials that have included this setting of population have shown similar survival rates and toxicities to younger patients. Age itself should not be considered for candidacy to chemotherapy but it should be taken in consideration the great heterogeneity of co-morbidities present in the elderly population. Therefore, the best treatment st…

Efficacy of poly(lactic acid)/carvacrol electrospun membranes against Staphylococcus aureus and Candida albicans in single and mixed cultures

2018

Carvacrol (CAR) is one of the most promising essential oil components with antimicrobial activity. New technologies aimed to incorporate this active molecule into carrier matrix to improve the stability and prolong the biological activity. The goal of this study was to investigate the feasibility of incorporating CAR into electrospun membranes of poly(lactic acid) (PLA) for potential applications as active antimicrobial system. To this end, PLA membranes containing homogeneously dispersed CAR were successfully prepared and a series of systematic tests including morpho-mechanical properties, in vitro release rate, and antimicrobial/antibiofilm activities against Staphylococcus aureus and Can…

Candida bloodstream infections in intensive care units: Analysis of the extended prevalence of infection in intensive care unit study

2011

Objectives: To provide a global, up-to-date picture of the prevalence, treatment, and outcomes of Candida bloodstream infections in intensive care unit patients and compare Candida with bacterial bloodstream infection. Design: A retrospective analysis of the Extended Prevalence of Infection in the ICU Study (EPIC II). Demographic, physiological, infection-related and therapeutic data were collected. Patients were grouped as having Candida, Gram-positive, Gram-negative, and combined Candida/bacterial bloodstream infection. Outcome data were assessed at intensive care unit and hospital discharge. Setting: EPIC II included 1265 intensive care units in 76 countries. Patients: Patients in partic…

Quality and Efficacy of Tribulus terrestris as an Ingredient for Dermatological Formulations

2013

Tribulus terrestris L. (Zygophyllaceae) is an annual plant commonly known as Puncture vine. It is dramatically gaining interest as a rich source of saponins. T. terrestris is a promising ingredient for many industries and recent patents on dermatological applications support the use of this plant for cosmetics and hygiene. Nonetheless problems arise in the selection of the material to be used. The extracts of different origins may differ substantially. Natural speciation processes normally influence ‘variations’ in wild-crafted medicinal plants. The genus Tribulus is emblematic. Taxonomic status of T. terrestris is complicated by the wide geographical distribution leading to high levels of…

Theoretical Study of Primary Reaction of Pseudozyma antarctica Lipase B as the Starting Point To Understand Its Promiscuity

2014

Pseudozyma antarctica lipase B (PALB) is a serine hydrolase that catalyzes the hydrolysis of carboxylic acid esters in aqueous medium but it has also shown catalytic activity for a plethora of reactions. This promiscuous activity has found widespread applications. In the present paper, the primary reaction of PALB, its native hydrolytic activity, has been studied using hybrid quantum mechanical/molecular mechanical (QM/MM) potentials. Free energy surfaces, obtained from QM/MM Molecular Dynamics (MD) simulations, show that the reaction takes place by means of a multi-step mechanism where the first step, the activation of the carbonyl group of the substrate and the nucleophilic attack of Ser1…

Aislamiento de Candida dubliniensis en un adolescente con estomatitis protésica

2005

Objetivos: Utilizar varios métodos que permiten la diferenciación entre Candida albicans y Candida dubliniensis en un intento de conocer si C. dubliniensis puede ser aislada de la cavidad oral de adolescentes con prótesis ortopédicas orales. Materiales y métodos: Se aislaron 12 cepas de género Candida procedentes de mucosa palatina y de soporte de prótesis de 12 pacientes adolescentes portadores de prótesis ortopédicas orales. Para la diferenciación entre C. albicans y C. dubliniensis se utilizaron varias pruebas fenotípicas (la asimilación de fuentes de carbono con el método comercial ID 32C, el crecimiento en agar glucosado de Sabouraud a 45 ºC, la producción abundante de clamidosporas en…
