Fission yeast is an excellent model system that has been widely used to study the mechanism that control cell cycle progression. However, there is a lack of tools that allow to measure with high precision the duration of the different phases of the cell cycle in individual cells. To circumvent this problem, we have developed a fluorescent reporter that allows the quantification of the different phases of the cell cycle at the single-cell level in most genetic backgrounds.

Scientific societies emphasize the importance of integrating quality of life (QoL) assessment in cardiovascular care. However, the association between QoL and weight remains understudied.

Introduction: For the microbiological diagnosis of bacteremia and fungemia, it is essential to use automated blood culture systems that guarantee good performance in the detection of microorganisms. We evaluated the BT24 system for blood cultures by comparing it with the BACTEC™ FX system in detection of positive spiked blood cultures (BC) and bottles, subsequent growth of the microorganism, and time to detection (TTD).
Methods: The parallel analysis of both systems was performed with 160 strains of 31 different species, each inoculated under the same conditions and simultaneously in six blood culture bottles.
Objective: Escherichia coli is isolated in most of uncomplicated community-acquired urinary tract infections (UTI) and fosfomycin is one of the treatments of choice. We analyzed the evolution of fosfomycin resistance in extrahospitalary E. coli urinary isolates and whether age and extended spectrum beta-lactamase (ESBL) production were associated to antibiotic resistance.

In fission yeast, entry into quiescence is triggered by nitrogen stress, leading to the inactivation of TORC1 and the activation of TORC2. In this study, we demonstrate that the Greatwall-Endosulfine-PPA/B55 pathway connects the downregulation of TORC1 with the upregulation of TORC2, resulting in the activation of Elongator-dependent tRNA modifications crucial for sustaining the translation programme during entry into quiescence.
