Women who used the once-a-week birth control patch, ORTHO EVRA® (norelgestromin/ethinyl estradiol transdermal system), were more likely to use their medication as directed than women who took a birth control pill, according to a study published in the current issue of Contraception.
"It’s not always easy, but it is very important for women using any birth control pill to take it at the same time every day to prevent unplanned pregnancy," said Vanessa Cullins, M.D. FACOG. "What’s exciting is that this study shows that the birth control patch is convenient and simple to use, and may be a better birth control option for women."
Oral birth control pills must be taken consistently and correctly to be effective, however an estimated 15 percent of oral birth control users say it is difficult to do so with the Pill. Inconsistent or incorrect use, i.e., missing one or more pills per cycle, can increase the risk of unplanned pregnancy and lead to abnormal bleeding, which is the leading cause of unscheduled physician visits. In the study, previously published Phase III data were analyzed to further explore compliance differences between ORTHO EVRA and an oral contraceptive. These results showed that the percentage of cycles with "perfect dosing," a measure of correct dosing of a birth control method, was significantly higher with the patch (88.7 percent) than oral contraceptives (79.2 percent).

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
