    Abstract: In recorded bioelectric signals, such as the electrocardiogram, sinusoidal interference from power lines or other sources causes distortion in the signal and may lead to misdiagnosis. For long or continuous recordings, adaptive filtering can be effective in minimizing the interference. For short recording, the options are limited. Subtractive metho... Show More

    Abstract: Background: In Ghana, the HIV-1 profile has been quite dynamic. Previous reports identified HIV-1 subtypes A, D and G present and recently the CRF02_AG has been described as the predominant molecular form of HIV-1 in Kumasi, Ghana. This underscores the need for constant molecular characterization of HIV-1 species in the country. Objective: To provi... Show More
