A Pilot Clinical Study on Post-Operative Recurrence Provides Biological Clues for a Role of Yeasts and Fluconazole in Crohn's Disease.

Background And Aims: This study prompted by growing evidence of the relationship between the yeast and Crohn's disease (CD) was intended to assess the effect of a 6-month course of the antifungal fluconazole (FCZ) on post-operative recurrence of CD.

Methods: Mycological samples (mouth swabs and stools) and serum samples were collected from 28 CD patients randomized to receive either FCZ ( = 14) or placebo ( = 14) before surgical resection. Serological analysis focused on levels of calprotectin, anti-glycan antibodies, and antibody markers of pathogenic transition.

Transient oxygen-glucose deprivation sensitizes brain capillary endothelial cells to rtPA at 4h of reoxygenation.

Thrombolysis treatment of acute ischemic stroke is limited by the pro-edematous and hemorrhagic effects exerted by reperfusion, which disrupts the blood-brain barrier (BBB) capillary endothelium in the infarct core. Most studies of the ischemic BBB overlook the complexity of the penumbral area, where the affected brain cells are still viable following deprivation. Our present objective was to examine in vitro the kinetic impact of reoxygenation on the integrity of ischemic BBB cells after oxygen-glucose deprivation.

High-throughput genomic analysis in Waldenström's macroglobulinemia.

Single-nucleotide polymorphism array (SNPa) and array-based comparative genomic hybridization (aCGH) are among the most sensitive genomic high-throughput screening techniques used in the exploration of genetic abnormalities in Waldenström's macroglobulinemia (WM). SNP and aCGH allow the identification of copy number abnormalities (CNA) at the kilobase level thus identifying cryptic genetic abnormalities unseen by lower-resolution approaches such as conventional cytogenetic or fluorescence in situ hybridization (FISH). CNA were identified in nearly 80% of cases by aCGH that delineated in addition minimal altered regions.
