Myotoxins are abundant components of snake venoms, being a significant public health problem worldwide. Among them, Lys49 phospholipase A2 homologue myotoxins cause extensive necrosis in skeletal muscle tissue. Their ...

We present here a six-species comparison of tree-ring growth response to extremes (below the 30th and above the 70th percentile) in temperature, precipitation, and corresponding streamflow. The species compared are Pinus ...

Between 1990 and 1992, 2 adult specimens of the ventrad spiderfish, Bathypterois ventralis Garman 1899, were collected at depths between 637 and 880 m off the Pacific coast of Costa Rica. These specimens constitute the ...

Modification of Bothrops asper myotoxin II, a lysine-49 phospholipase A2 variant, was carried out with p-bromophenacyl bromide. Modified toxin did not show changes in its charge and immunological properties but two of its ...

The origin of minor leucocratic intrusions known as “plagiogranites” in oceanic complexes dominated by basaltic compositions have been debated in the literature. Here we use well preserved plagiogranites within the contrasting ...
