| a scanning electron-microscopic study of in vitro abrasion of mammalian tooth enamel under compressive loads. | microscopic tooth-wear (microwear) patterns can be an important tool for assessing modes and rates of abrasive tooth wear, but their analysis and interpretation is complicated by the fact that microwear is influenced by many factors. three of these factors were here tested under conditions of compressive loading: (1) species differences in enamel structure, (2) abrasive particle size and (3) magnitude of force. teeth of four species (homo sapiens, lemur fulvus, ovis aries and crocodylus rhombife ... | 1994 | 8179503 |
| alpha-2-macroglobulin-like protease inhibitor from the egg white of cuban crocodile (crocodylus rhombifer). | a high molecular weight protease inhibitor was purified from the egg white of cuban crocodile (crocodylus rhombifer). it inhibited the casein hydrolyzing activity of trypsin, subtilisin and papain. its native molecular weight was 730,000 and it consisted of four subunits of equal molecular weight, each pair of which were disulfide bonded. the amino acid composition, circular dichroic spectrum and electron micrographs of this protein are also presented. upon incubation with trypsin this protein y ... | 1983 | 6188750 |
| some helminth parasites from morelet's crocodile, crocodylus moreletii, from yucatan, mexico. | an examination of three specimens of the morelet's crocodile, crocodylus moreletii duméril et bibron, from the lagoon of celestún, yucatan, mexico revealed the presence of the following eight helminth species: acanthostomum americanum (pérez vigueras, 1956), pelaezia loossi (pérez vigueras, 1956), telorchis sp. juv., pseudoneodiplostomum groschafti sp. n. (all trematodes), dujardinascaris helicina (molin, 1860), contracaecum sp. type 2 larvae, micropleura sp. and paratrichosoma recurvum (solger, ... | 2001 | 11266135 |
