Open AccessPre-treatment minority HIV-1 drug resistance mutations and long term virological outcomes: is prediction possible?
Although the use of highly active antiretroviral therapy in HIV positive individuals has proved to be effective in suppressing the virus to below detection limits of commonly used assays, virological failure a...

Retrospective review of MEG visual evoked hemifield responses prior to resection of temporo-parieto-occipital lesions
Visual evoked cortical magnetic field (VEF) waveforms were recorded from both hemifields in 21 patients with temporo-parieto-occipital mass lesions to identify preserved visual pathways. Fifteen patients had v...
