A GPS receiver flying on the High Earth Orbit (HEO) AMSAT-OSCAR 40 (AO-40) spacecraft has been returning GPS observations from high above the altitude of the GPS constellation. AO-40, an amateur radio satellite launched November 16, 2000, is currently in a low inclination, 1000 by 59000 km altitude orbit. This low-cost experiment utilizes a mid 1990’s era, 6-channel, C/A code receiver configure...

Envenoming by Echis saw-scaled viper is the leading cause of death and morbidity in Africa due to snake bite. Despite its medical importance, there have been few investigations into the toxin composition of the venom of this viper. Here, we report the cloning of cDNA sequences encoding four groups or isoforms of the haemostasis-disruptive Serine protease proteins (SPs) from the venom glands of ...

The usage of the name Rana ocellata Linnaeus, 1758, is plagued by misidentifications and misinterpretations. After an exhaustive bibliographic review, we conclude that the Linnaeus 1758 name refers to Osteopilus brunneus (Gosse, 1851) from Jamaica, while the taxon currently known as Leptodactylus ocellatus corresponds to Rana latrans Steffen, 1815. Herein, we designate and provide descriptions ...

Envenoming by Echis ocellatus is potentially life-threatening due to severe hemorrhage, renal failure and capillary leakage. These effects are attributed snake venom metalloproteinases (SVMPs). ...

in this study, we have investigated the effects of mix of tomato (solanum lycopersicum) & carrot) daucus carota ( and red bell pepper )capsicum annuum( as a natural pigment source and astaxanthin as synthetic pigment sources on the skin colour of cichlid fish (astronotus ocellatus sp., agassiz, 1831), which are generally white with red patches in the dorsal skin. the fish were fed diets con...

Three species of the ophidiid genus Neobythites containing ocelli in the dorsal fin are known from the West Atlantic: Neobythites gilli Goode and Bean 1885, N. ocellatus Günther 1887 and N. monocellatus Nielsen 1999. In the year 2000, 18 specimens of Neobythites were caught on the upper continental slope off eastern Brazil. This is the first documented record of a Neobythites specimen off Brazi...

Thin-section studies of the sino-auricular border region in the hearts of 20 species of teleost fish revealed the cardiac internuncial cell (CIC), hitherto known only in Misgurnus, to occur also in 8 species (Acheilognathus lanceolatus, Carassius auratus longsdorffii, Cyprinus carpio, Girella punctata, Kareius bicoloratus, Rhodeus ocellatus ocellatus, Rhyncopelates oxyrhynchus, Tilapia nilotica...

The anti-snake venom activities of the methanolic extract of the bulb of Crinum jagus plant (Amaryllidaceae) were investigated in vitro and in vivo against the venoms of three notable snake species: Echis ocellatus, Bitis arietans and Naja nigricollis. The extract was prepared by cold marceration in 50% methanol at 37 degrees C with intermittent shaking for 48 h. An yield of 12.8% w/w dry extra...
