[Course of the anaesthesiology and intensive care unit residents in Lorraine, France].

Objective: The anaesthesiology and intensive care physician demography is becoming critical in most French regions; more than 56% of the residents trained in Lorraine are leaving the area after they graduate.

Methodology: A descriptive and retrospective survey was carried out. The aims of the research were threefold: to ascertain firstly, why residents chose Lorraine in the first instance, secondly their experiences of the training and thirdly their expectations.

[Assessment of hygiene practices in anaesthesia between 1998 and 2007 in Lorraine].

Objectives: To study the assessment of hygiene practices in anaesthesia in Lorraine between 1998 and 2007, after recommendations from the French Society of Anaesthesia and Reanimation (SFAR) in December 1997, and different local actions.

Study Design: Two surveys performed at a nine-year interval in Lorraine hospitals.

Population And Method: Questionnaires about risk infection management and hygiene practices were sent by post to all anaesthetists, nurse anaesthetists and recovery room nurses in 1998 (n=279) and in 2007 (n=259).

Linewidth reduction by 6 orders of magnitude of a broad-area 729-nm diode laser.

Diode lasers with a power output superior to 100 mW are in widespread use in medical as well as research applications. However, for such diodes lasing oscillation generally occurs simultaneously in several longitudinal and transverse modes that are unsuitable for high-resolution spectroscopy. We spectrally narrow a 100-mW broad-area diode laser by first using an extended cavity and then an electrical feedback produced by a Pound-Drever-Hall stabilization on a low-finesse reference cavity.

Replication protein A is required for meiotic recombination in Saccharomyces cerevisiae.

In Saccharomyces cerevisiae, meiotic recombination is initiated by transient DNA double-stranded breaks (DSBs). These DSBs undergo a 5' --> 3' resection to produce 3' single-stranded DNA ends that serve to channel DSBs into the RAD52 recombinational repair pathway. In vitro studies strongly suggest that several proteins of this pathway--Rad51, Rad52, Rad54, Rad55, Rad57, and replication protein A (RPA)--play a role in the strand exchange reaction.
