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.

  • Charles Boston - Solid bike

    This is a pretty solid bike for the price. At 6' 00" with 32.5" inseam, this bike is the right size. However, if you are shorter than 5' 11", you may want to consider the medium size (even though Diamondback size chart says 5' 10" is ok) as this bike runs a bit large. It DOES NOT include the assembly tools (confirmed!!). Assembly was pretty easy, but you can't go by the absolutely useless instruction book (look to their website for guidance instead). Most of the bike was already assembled. After 1 hour basic assembly, I had brake noise on rear brake/rotor and noise from chain rubbing against the front derailleur. Knowing absolutely nothing about bikes, it took several youtube videos and another 3 hour to fine tune it. This included adjusting rear brake pad position, rear brake cable tension, and bending the rear rotor just a bit. On the front derailleur, I adjusted tension as well as the high and low limit on front derailleur. They seemed pretty difficult at first, but once you get through it, it will be much easier if you need to do it again. I then made sure that everything was tight and secure, in case someone at the factory was incompetent. Now it shifts very quickly, smoothly and quietly. The brakes stop effectively with no noise at all.
