Postovulatory effects of Levonorgestrel in emergency contraception


Hello to all, today I going to talk about the speech of the Dr. Valenzuela over the Postovulatory effects of Levonorgestrel in emergency contraception.
The presentation was very interesting for me because the Dr. Valenzuela talk about topics nearly to our career.
The Levonorgestrel is a type of Progesterone, used in the monophasic and triphasic formulation of combined oral contraceptives pills in low doses. The other use and the most important, is in the Emergency contraceptives pills (ECPs) both in a combined Yuzpe regimen which includes estrogen, and as a Levonorgestrel only method. And the final use and less important is in the intrauterine contraceptive device with progestogen.
Levonorgestrel in form of ECPs is used 24 to 120 hours after unprotected sex, with a maximum effectiveness in the first three days.
I am agree with the use of Levonorgestrel as Emergency contraceptive pills but in only one instance and it is when a woman is violated and she didn’t want to get pregnant, because first would be an unwanted pregnancy and second she didn’t the possibility of use an contraceptive method. For this to my mind the pill shouldn’t be give to the women that haven’t was violated because they have the option of use an contraceptive method or demand to their couple that they use a preservative.
Dr. Valenzuela doesn’t consider that the Levonorgestrel is abortive, and I agree with him, because the life begin when the Nervous System begin to develop, and the Levonorgestrel exerts its effect before than it does occur.

Iron Maiden, My Favorite Rock Band


Hello to all, today I going to talk about my favorite rock band, this is Iron Maiden, it is an British band of heavy metal.
Iron Maiden was founded for Steve Harris, the only original member, in the 1975. The name of the band is based on an object of torture that Steve saw in the movie “The Man in the Iron Mask”.
Iron Maiden is composed for Bruce Dickinson, that is the vocalist; Dave Murray, Adrian Smith, Janick Gers, that are the guitarists; Steve Harris, that is the bassist; Nicko McBrain, that is the drummer; and Eddie the Head, that is the icon of the band.
The Discography of the band is: Iron Maiden (1980), Killers (1981), The Number of the Beast (1982), Piece of Mind (1983), Powerslave (1984), Somewhere in Time (1986), Seventh Son of a Seventh Son (1988), No Prayer for the Dying (1990), Fear of the Dark (1992), The X Factor (1995), Virtual XI (1998), Brave New World (2000), Dance of the Death (2003), A Matter of Life and Death (2006) and The Final Frontier (2010).
My favorite’s songs are: The Number of The Beast, The Wicker Man, Powerslave, Journeyman, Rainmaker, Blood Brothers, Montsegur, and Satellite 15…The Final Frontier.
The songs that I dislike are the songs of the discs The X Factor and Virtual XI, because in this discs Bruce Dickinson didn´t stay in the band and was replaced for Blaze Bayley that have a voice most soft that Bruce.
Actually the band is in a tour for their ultimate disc The Final Frontier and I wish that they will come to Chile, because in the previous concerts I didn´t can go.
