"Conformational" isoenzymes of ascarid enolase.
The present studies were initiated to determine the biochemical basis fo r the existence of multiple, electrophoretically distinct enolase activities in the parasitic round worm Ascaris suum. A total of five activities were resolved by electrophoresis of worm body fluids on cellulose polyacetate strips followed by staining the strips specifically for enolase activity. These activities are refer...
متن کاملA new ascarid species in cynodont coprolite dated of 240 million years.
Cynodonts represent the transition from reptiles to mammals. They are classified as synapsids, or tetrapod animals with mammalian characteristics. We present here the finding of helminth eggs in a coprolite identified as of cynodont origin dated of nearly 240 million years. Microscopy revealed the presence of very well preserved intestinal parasite eggs. Up to now we identified an ascarid egg b...
متن کاملOTTER Proofs in Tarskian Geometry
We report on a project to use OTTER to find proofs of the theorems in Tarskian geometry proved in Szmielew’s part (Part I) of [9]. These theorems start with fundamental properties of betweenness, and end with the development of geometric definitions of addition and multiplication that permit the representation of models of geometry as planes over Euclidean fields, or over real-closed fields in ...
متن کاملVocal repertoire of the social giant otter.
According to the "social intelligence hypothesis," species with complex social interactions have more sophisticated communication systems. Giant otters (Pteronura brasiliensis) live in groups with complex social interactions. It is likely that the vocal communication of giant otters is more sophisticated than previous studies suggest. The objectives of the current study were to describe the air...
