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.

The stub antenna on my wife's Toyota Rav4 disappeared one day - unscrewed, fell off, stolen - who knows? Mainstream dealers wanted absurd amounts for a replacement stub antenna, so headed for Amazon.com to do some research.
I'm always concerned about buying cycle shoes online, because the fit is so very different across not only brands but also styles within one brand.
The author takes a searching look, based on good data at how our nation is being polarized between the elite 1 or 5% who he demonstrates have the "power" and the lower 30% (economically). I was not surprised to read how the elites operate, segregate themselves. What was startling was the deterioration and demoralization of the lower 30% in our society. By avoiding race as an issue, he points out some striking facts, which do not become side-tracked by the issues of racial politics. Chilling. A must-read if you have any concern about where our nation is headed, with no political polemics to obscure the discussion. This book is not about politics, but a shocking look at what has happened while we were not paying attention. His notations, scholarship are impeccable. He writes well, smoothly, as it were. Buy this book and encourage all your literate friends to do likewise.
