Combination of different molecular mechanisms leading to fluconazole resistance in a Candida lusitaniae clinical isolate.

We report on the underlying molecular mechanisms likely responsible for the high-level fluconazole resistance in a Candida lusitaniae clinical isolate. Fluconazole resistance correlated with overexpression of ERG11 and of several efflux pump genes, in particular, the orthologs of the Candida albicans MDR1, PDR16, CDR1, CDR2, and YOR1.

Assessment of circadian rhythms by actimetry in healthy subjects and patients with advanced colorectal cancer.

Circadian rhythms can be altered in severe illness such as cancer; the rest-activity circadian cycle has been used as a reference for the administration of chemotherapy at specific times in order to improve tolerability and efficacy. We assessed the feasibility of the method in our center in a sample of patients with metastatic colorectal cancer selected for chronomodulated chemotherapy. Activity of the circadian rhythms were measured non-invasively in 10 patients with metastatic colorectal cancer by wrist actimetry, and compared to healthy subjects.
