This new research expands understanding of the risks of drug resistance connected with single-dose nevirapine, but as observed by all three study groups, the clinical implications for patients are not yet clear. More study will be needed to determine whether nevirapine used to prevent mother-to-child transmitting affects the chances of successful treatment later with nonnucleoside reverse transcriptase inhibitors, the class of medication to which nevirapine belongs. Two of the research analyzed the incidence of nevirapine-associated resistance using laboratory tests more sensitive than regular genotypic assays.He went on to say that ‘scientists reported with unprecedented alarm that the North Polar icecap is normally, in their words, ‘falling off a cliff.’ One study estimated that maybe it’s completely gone during summer time in under 22 years. Another new research to be provided by U.S. Navy researchers later this week warns that it might happen in as little as seven years, seven years from now.’ And Maslowski himself told associates of the American Geophysical Union the same season that the Arctic’s summertime ice could totally disappear within the decade.
