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.

I bought the wrong item because there is no reference that this upgrade just works in USA and not for our TVs sold here in Brazil. The sellers and the Samsung could be more clear selling this stuff. The item that works for me is the SEK-1000/ZD. I Did not Know that this "D" could made ''all the difference. I'm feeling frustrated.
Not bad but a little hard to adjust to the lay position unless you put your feet in a weird possition. And the head cussion thing kinda popped off. Id give it a 3 1/2 but i rounded up because its pretty decent to lay on.
Problem from installation. 5 times was implied I needed to download again. got notice "malware"may have been "added on" The one time seemed to work-stopped working and couldn't recapture data Too much trouble and red flags for this software. Got numerous messages after I responded to an "error message" on how to "fix". Was so complex for an average consumer and all the previous trouble, I decided to cut my losses and time.
