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.

In over 6 years of using Amazon I am writing my first review, these are horrible and do not fit in the back row.
Choke. This stuff smells awful. Fragrance in something that's supposed to be "healing"? Really? Maybe I'll be able to stand it outdoors when winter comes, but will definitely not buy again.
Loved the book. I use it as a reference all the time. Whenever, I forget anything, I just look it up and finish my job.
I have this set up for my home office. It was much bigger than I anticipated, but the resolution is perfect! I don't use it for gaming, but I have tried a couple games on it and it looks clear for those as well.
After using it now for about two months it has performed flawless so far and it does not slow down my computer at all that I can tell. To this point I can recommend it to anyone else without hesitation.
Always a great reference. I get it every year. I find very little different in terms of tips from last year's edition and that makes me wonder if I should still keep buying it. The Kindle edition for IPad is great.
