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.

  • Michael Moskowitz - The screen is great, the machine is fast--like really fast

    For the money, this is kind of hard to beat. The screen is great, the machine is fast--like really fast. You flip the lid open and it's up and running with virtually no boot up time. Pretty impressive. When you take into account that most of us spend 99% of our time on the internet AND all of the best productivity programs (Google docs, Microsoft Word) are already available as online web programs, there is really very little reason to use a dedicated desktop/laptop for most users unless you need proprietary software (i.e. autocad, video/audio editing, etc..) and more raw processing power. I really can't think of any cons at this price. The only one being some additional steps you need to take to set up a virtual Google printer. Keyboard is good, unit is light yet feels sturdy and the dedicated chrome keys are cool. I'm getting another one for my office.

  • Louise C. Cherry - Does the job

    Used the program for a new will, a end of life directive/medical directive. Program does what it says it will do.

  • Gompers - Not helping sagging

    This does well for moisturizing my neck, the "fish " smell is there but disappears quickly and this product does nothing to help sagging.

  • Amazon Customer - Decent and functional

    Nice case for the price. Works and fits well. Stands fine, but my main negative comment is the aesthetic.. It's a little TOO shiny black for me.. Like the look of greasy oiled leather.

  • Amy L. Delisle - great quality

    Needed this for a class- great quality I was worried it might start to rip as I use it every day however, the pages are staying intact. not issues

  • Harriet I. Williams - Ease of Transition

    After opening it up, I appreciate the access to step by step comprehesible directions for how to get the program set up and working for my company. I am not an accountant or business manager, so as the sole proprietor, I have to do it all and it's good to know that I have the support to make it work for my small business.

  • Amazon Customer - Not a realistic review for the ACT

    According to the students I tutor for the ACT - most of whom have taken the test at least once - they tell me that this book presents questions and problems more difficult than is what on the actual test. I guess there could be a reason favoring practice harder than the test, but I find that students get frustrated and thus overlook the fundamental concepts that have a higher probability of being on the test.
