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.

A sequel to "Losing Ground", Murray illuminates the social trends subsequent to 1980, and it isn't pretty. Accurate perhaps, but discouraging as the United States devolves into a society of classes.
1000 mg capsules are really scarce and being ridiculously over-priced because of it. I want the 1000not really the 500 - I take enough pills! But I will buy these if I have to. The Twinlab product is the best Niacin available. Purpose is good for many reasons, but I buy it to stimulate brain function. (It does work but you need 4-5 grams / day.)
I never knew battery charging and repairing could be so easy! All these years I've been buying junk charger after charger. They all fail in a year or so, darn junk peddlers... I can't see buying anything any different than what this little box accomplishes. I have so many batteries that I thought were junk just piling up. Turns out a bunch of them are just fine, they just needed a little help from this thing. I went through our vehicles and charged each battery, now the engines seem to turn over a lot faster when starting and the batteries seem to stay pretty fresh.
