INTRODUCTION Increasing the knowledge of women on effectiveness of contraceptive methods can lead to the use of more effective methods and reduce unwanted pregnancies and adverse outcomes. We aimed to compare three different approaches for increasing women's understanding of effectiveness of contraceptive methods. METHODS We ran-domly assigned 630 eligible women of reproductive age to one of ...

Dipping tests with DDT for the control of three species of goat lice, two Mallophaga and one Anoplum, were conducted at Menard, Tex. Angora goats infested with the yellow louse, Trichodedes lzermsi Kellogg and Nakayama, and the red lice, T. Cf/prae Gurlt and T. limbatus Gervais, were dipped in 0.3 and 0.6 per cent of the cbemical in a water emulsion. In every case all the lice were killed soon ...

Eight sublines ofthe radiation-induced lymphoma S-l033 of C57BL/ 10 (hereafter called BlO) origin were established by exposing the cells in vivo to eight antineoplastic agents for a number of transplant generations. The parental and drug-treated sublines were tested for immunogenic proper ties, i.e., the ability to elicit allograft reactions in the host of origin and in congenic-resistant mice ...

alkaloids of the aerial parts of chelidonium were extracted in the salt form, and their aqueous solutions were prepared in different concentrations. rat hepatocytes were obtained by liver perfusion. the alkaloidal solutions were added to suspensions of hepatocytes in petri dishes and the mixtures were incubated. two types of controls have been used in one type. no alkaloidal extract was added t...

Most of the cost of information system implementation projects is attributable to the post-adaptation phase. Thus, an effective use of the implemented system is necessary to justify the expense. It has been theorized that user adaptation can help to increase the level of effective use of a system. Changes to an enterprise system or to the individual’s tasks with an enterprise system are likely ...

Reports describe the association between platelet activation, adhesion, and aggregation, as well polymorphisms in genes encoding membrane glycoproteins with a predisposition to coronary artery disease (CAD). This study investigates associations HPA-1, -3 C807T CAD. A cross-sectional involving 114 women who underwent angiography was performed. The CAD+ group consisted of 63 while CAD- 51 women. ...

Alkaloids of the aerial parts of chelidonium were extracted in the salt form, and their aqueous solutions were prepared in different concentrations. Rat hepatocytes were obtained by liver perfusion. The alkaloidal solutions were added to suspensions of hepatocytes in petri dishes and the mixtures were incubated. Two types of controls have been used in one type. no alkaloidal extract was ad...

We report evidence for a structural phase transition in individual suspended metallic carbon nanotubes by examining their Raman spectra and electron transport under electrostatic gate potentials. The current–gate voltage characteristics reveal anomalously large quasi-metallic band gaps as high as 240 meV, the largest reported to date. For nanotubes with band gaps larger than 200 meV, we observe...
