La doxycycline, membre de la famille des tétracyclines, agit par inhibition de la fixation de l’ARNt sur la sous-unité 30S du ribosome, empêchant l’élongation de la chaîne peptidique. Elle se caractérise par un spectre très large incluant bactéries atypiques, rickettsies, chlamydiae et spirochètes. Sa biodisponibilité digestive est excellente, mais elle est diminuée en cas d’ingestion simultanée de sels de calcium, fer ou magnésium. La doxycycline diffuse bien dans les tissus et possède une demi-vie longue, permettant des administrations biquotidiennes. Elle est éliminée principalement par voie biliaire. Les précautions concernent le risque de photosensibilisation, d’hyperpigmentation dentaire et de troubles digestifs. Dans les recommandations cliniques, la mention doxycycline sans ordonnance est souvent accompagnée de rappels sur la nécessité d’éviter son usage chez l’enfant et la femme enceinte, ainsi que sur la surveillance des traitements prolongés.

I love this stuff. It is the only product I have used where I feel the difference in my skin immediately. Will use forever!
Bought it two weeks ago. Came in a medium sized box (2 days shipping) and it opened up like a Jack-in-the-box. Smell went away within 1 day (it's not sprayed with those fireproof chemicals). Very comfy. Soft top yet firm support. My side back pain feels much better. I tried the Tempurpedic and this mattress is much better.
My dishwasher was not completely draining. I took out the old piece and put this and it worked like brand new. Make sure you have the right dishwasher though.
Band makes product useless. Impossible to get on for an older person. Thingie with prongs -- which passes for an el cheap clasp -- does not seat properly. This in turn makes it very difficult to insert the prongs into the band to secure it. Other than being waterproof, I cannot imagine a band that is designed more poorly.
This MCAT review book is decent for biology, general chemistry, physics...but definitely not organic chemistry. I don't know what was wrong with the team in charge of editing this section, but there are a plethora of errors and erroneous diagrams. Don't take what is said in this book as solid truth because you will get those concepts wrong on the mcat. Additionally, there seems to be a problem with kaplan's printing company. On several figures in blue, there are noticeable cutoffs which confuse an H2O for H2C, for example.
