A comparative trial of copper T 380 and Cu 375 IUCD.
BACKGROUND The IUCD, primarily in the form of copper IUD is used by more than 150 million women around the world, making it the most widely used reversible method of contraception. The objective of this study is to do double blind clinical trial to compare the side effects of Copper-T and Cu 375 IUCD in women using contraceptive method and had used no contraception before. METHOD A total of 8...
متن کامل1,1-Diamino-2,2-dintroethene (FOX-7) in copper and nickel diamine complexes and copper FOX-7.
1,1-Diamino-2,2-dinitroethene (FOX-7) reacts readily with copper nitrate in an aqueous solution of potassium hydroxide to form pea green Cu(FOX)(2)(H(2)O)(2) (5). FOX-7 complexes of copper and nickel supported by a variety of diamines including Cu(en)(2)(FOX)(2)(H(2)O) (1), Cu(pn)(2)(FOX)(2) (2), Cu(bipy)(FOX)(2)(H(2)O)(4) (3a), Cu(bipy)(2)(FOX)(2)(H(2)O)(2.5) (3b), Cu(bipy)(FOX)(2)(DMSO)(2)·2D...
متن کاملIntrauterine contraception with the copper 7: evaluation after two years.
From 1,156 insertions of the copper 7 contraceptive device with 15,044 women-months of use we conclude that it offers advantages in intrauterine contraception. Continuity is improved for all users. It is a useful method for those who have not been pregnant and as an exchange device for patients having problems with other intrauterine devices or contraceptive methods. These advantages must be se...
متن کاملCorrelation of Copper Interaction, Copper-Driven Aggregation, and Copper-Driven H2O2 Formation with Aβ40 Conformation
The neurotoxicity of Aβ is associated with the formation of free radical by interacting with redox active metals such as Cu(2+). However, the relationship between ion-interaction, ion-driven free radical formation, and Aβ conformation remains to be further elucidated. In the present study, we investigated the correlation of Cu(2+) interaction and Cu(2+)-driven free radical formation with Aβ40 c...
متن کاملElectroleaching of Copper Waste with Recovery of Copper by Electrodialysis
A new process to leach and recover copper from solid waste using electric fields was designed. The leaching with electro migration is presented as an alternative to traditional leaching. Preliminary data indicate that the copper ion migration is facilitated by using the electrical potential difference; therefore applying a potential difference in the processes of leaching facilitates the remova...
