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.

  • aiRCoft - I'm a big fan of Zippo products, but this is terrible....

    I really do like the brand "Zippo", and I own dozens of their lighters and products, but this hand warmer simply doesn't work. I ordered one a while back, and it didn't seem to work no matter what I did to it, so I returned it and got another, thinking it would work better. I read the ALL of the instructions and followed them both times, and still it did not work. It says that it lights in 3-5 seconds, but that is a total lie. My first one never lit, and my second one did light after about 2 minutes of holding a Zippo lighter's flame to it, and then the heat only lasted a few minutes, and the catalytic burner went out.... I really, really do like Zippo, don't get me wrong, but this is a very bad design and I would definitely not recommend it. Stick to the disposable ones that you can get for around $1. If Zippo ever decided to redesign this product or make a new version of a hand warmer, I would buy it without a doubt, but I am not satisfied with this one. (The only reason I didn't give this product a one-star rating was because I like the little bag it came with, the butane measuring cup, and I like the looks of the stainless steel design of the hand warmer itself.)

  • spammy0124 - Webroot SecureAnywhere 2013 review

    Webroot SecureAnywhere was the only product of five anti-virus products I tried that found and eliminated a nasty rootkit that was on my PC. The scan is very fast and the product does NOT bog down my machines. The is an excellent anti-virus and web security product and for the money, an outstanding buy.
