Assessing the Response of Small RNA Populations to Allopolyploidy Using Resynthesized Brassica napus Allotetraploids.

Allopolyploidy, combining interspecific hybridization with whole genome duplication, has had significant impact on plant evolution. Its evolutionary success is related to the rapid and profound genome reorganizations that allow neoallopolyploids to form and adapt. Nevertheless, how neoallopolyploid genomes adapt to regulate their expression remains poorly understood.

[Anesthesia for video-assisted surgery of the thoracic and lumbar spine: a survey of 44 patients].

Introduction: The development of video-assisted surgery of the dorsolumbar spine has led to the need for adaptations for appropriate anesthetic management. Data concerning anesthesia for such surgery is very sparse in the literature.

Aim Of The Study: The aim of this retrospective study of 44 patients was to learn more about anesthesia practices used for patients undergoing this type of surgery.

[Risk assessment before non-cardiac surgery: what do anesthesiologists expect from cardiologists?].

Patients with a cardiac pathology are at high risk of perioperative cardiac complications. Therefore, an evaluation of the cardiac risk before a non-cardiac surgery has to be performed. The importance of the risk depends on the type of surgery, the patient's clinical symptoms and his adaptation to a physical effort.

[Determination of 3-methoxy-4-hydroxyphenyethylene-glycol and its urinary conjugates. Value in the diagnosis and therapeutic follow-up of depression].

In psychiatric illness like depression, difference is essential between noradrenergic and serotoninergic sources. Therefore the measurement of urinary excretion of MHPG (3-methoxy-4-hydroxy-phenylethylene-glycol) is interesting, because MHPG seems to be the best reflect of central noradrenergic activity. Analytical assay of MHPG includes an enzymatic hydrolysis and an extraction by ethyl acetate.
