Fluorescence polarization assay of plasmin, plasminogen, and plasminogen activator

A chromatographic method involving medium-pressure liquid chromatography on alumina impregnated with silver nitrate is described for the separation of a series of closely related C₂₇ sterol precursors of cholesterol differing only in the number and location of olefinic double bonds. The features of the described system are compared with those of previously described thin-layer, gas-liquid, gravity column, and high-pressure liquid chromatographic methods.     

Type Specimens and identity of the described species of Conus II. The species described by Solander, Chemnitz, Born, and Lightfoot between 1766 and 1786

Twenty-three species of Conus were described by authors other than Linnaeus between 1766 and 1786. Of these, 3 are Eocene species from England described by Solander in Brander (1766), and the remainder are Recent. Chemnitz (1777) described one valid species. Of the 10 species described by Born (1778), 7 are valid, 2 are junior synonyms of Linnaean species, and 1 is a nomen dubium. Solander in [Lightfoot] (1786) described 5 species, of which 3 are valid and 2 are junior synonyms of Linnaean species. Lightfoot (1786) described 4 species, of which 1 is valid and 3 are junior synonyms of Linnaean species.
Holotypes of 7 species and lectotypes of 3 species exist, and representatives of lecto-types of 10 species have been selected. All of these types are illustrated photographically.
Between 1758 and 1786, 60 species of Conus were described, of which 45 are now considered valid. Of these, 42 are Recent.

Ademosynoides asiaticus Martynov, 1936, the earliest known member of an extant beetle family (Insecta, Coleoptera, Trachypachidae)

Fossil beetles are described from Kedrovka beds of the locality Babii Kamen’, Kuznetsk Basin, Siberia. According to different authors, this locality is dated to the terminal Permian or basal Triassic. SEM studies have shown that Ademosynoides asiaticus Martynov, 1936, described from this locality, should be placed in the family Trachypachidae, which makes it the earliest known extant family of beetles. In addition to the re-studied holotype, further material is described for this species; a new species of the same genus and a new genus and species of the same family are also described. As a result, almost 10% of the 78 beetle fossils known from this locality are identified as belonging to Trachypachidae. Unfortunately, the study of these beetles is complicated by the rather poor preservation quality and very small size of the majority of the fossils, which usually cannot be properly studied without using SEM. However, even in this case there is no full certainty that the results are absolutely reliable.

Cheiriphotis trifurcata is characterized by its trifurcated tip of the modified setae on the outer ramus in male pleopod 3. In this paper, the new species is fully described and compared with related species and a complete key of the 16 valid species in the genus Cheiriphotis is given.     

Permian terebratulids of Eurasia: Morphology,systematics, and phylogeny

The Permian terebratulids of Eurasia are revised. The taxonomic composition of the Permian terebratulids of the Russian Platform, Northern Caucasus, Transcaucasia, northern and southeastern Pamirs, and northern China (Inner Mongolia) is elucidated. Fifty-one species (13 described here as new), 21 genera (3 described here as new), 7 families, and 6 superfamilies are described. During the progress of the study, the author (Smirnova, 2004a, 2004b, 2006a, 2006b) and Smirnova and Grunt (2002, 2003a, 2003b) described for the first time 19 species, nine genera, two families, and one superfamily. Morphofunctional analysis reveals a great diversity of internal structures, of the time of their appearance in the ontogeny, and of their taxonomic significance. Ontogenetic study reveals phylogenetic relationships between the Permian and Meso-Cenozoic terebratulids, the presence of the superfamilies Terebratuloidea and Loboidothyroidea in the Permian, and a new type of brachidium ontogeny characterizing the superfamily Compositelasmatoidea. This book is intended for paleontologists and biologists interested in problems of taxonomy and phylogeny, and includes 5 plates, 80 figures, and 75 bibliographic references.

The genus Unixenus Jones, 1944 (Diplopoda, Penicillata, Polyxenida) in Australia

The penicillate genus Unixenus Jones, 1944 is widespread, with species found in Africa, Madagascar, India and Australia. Each of the two Australian species was originally described from single samples from Western Australia.

A new species of Polymastia (Porifera, Hadromerida, Polymastiidae) from the Aleutian Islands, Alaska, USA

Polymastia fluegeli n. sp. is described from deep water off the Aleutian Islands (Alaska, USA). P. fluegeli is disc-shaped and lives partly buried in the sediment, with only the papillae protruding above the surface. This new species has a basal layer of agglutinated sediment particles occurring between the choanosome and the ectosomal lower layer. This conspicuous sediment layer is not described for other species of Polymastia. Occurring spicule types and sizes are different from known species of the area.     

Advances,Problems, and Prospects of Genetic Transformation of Fungi

Advances, problems, and prospects of genetic transformation of fungi are described. Features distinguishing fungi from other organisms are analyzed. Those features should be taken into consideration while preparing genetic material for transformation. The ways to overcome problems associated with hyphae apical growth, cell wall thickness, the heterokaryotic life cycle stage, and mechanisms of immune defense are described. A comparative analysis of major methods for transformation of fungi at different stages of their life cycle was performed. Stability of genetically modified fungi and advances in transformation are discussed.
