A preliminary result from Markarian 421 observations in the energy region above 10 TeV with the CANGAROO-II 10 m telescope is presented. In January 2001, the HEGRA group reported that Markarian 421 had become very active, with flux levels up to 4 times that of the Crab Nebula. As a result, we observed Mkn 421 during six nights from Jan-uary 24th to February 1st, and four nights from March 1st t...

Untreated tropical parasitic co-infections appear to speed the progression of HIV-1 disease. However, to date, there have been few studies conducted in resource limited settings to ascertain the interaction of parasitic co-infection where HIV/AIDS management largely depends on CD4+ T lymphocyte cells counts and WHO clinical staging. This study aimed to determine the prevalence of parasites, the...

To date, only two extragalactic objects have been firmly established as very high-energy gamma-ray sources in the Northern sky: these are the two blazars Markarian 501 and Markarian 421. This paper reviews the most striking results obtained from these sources by the CAT atmospheric Cherenkov imaging telescope, with a particular emphasis on the 1999-2000 and 20002001 observation campaigns of Mar...
