To delineate segments of the genome of the human protozoan parasite Leishmania major necessary for replication and expression, we developed a vector (pR-NEO) which can be reproducibly introduced into L. major. This DNA was derived from a 30-kilobase extrachromosomal amplified DNA bearing the dihydrofolate reductase-thymidylate synthase gene, with the coding region for neomycin phosphotransferas...

We compared the Neo-Sensitabs tablet assay to both reference M27-A2 broth microdilution and M44-A disk diffusion methods for testing susceptibilities of 110 isolates of Candida spp. and Cryptococcus neoformans to amphotericin B, caspofungin, fluconazole, itraconazole, and voriconazole. Neo-Sensitabs assay inhibition zone diameters in millimeters on three agars (Mueller-Hinton agar supplemented ...

In psychiatric outpatients, the usefulness of the dimensional NEO-FFI as a screening instrument for personality disorders (PDs) was compared with the categorical screening instrument SAPAS-SR using the SCID-II as the gold standard. Major research questions are: 1) is the NEO-FFI a useful screening instrument for PDs? 2) does the NEO-FFI outperform a categorical screening instrument (SAPAS-SR)? ...

Using a small near-Earth object (NEO) to impact a larger and potentially threatening NEO has been suggested as an effective method to avert a collision with Earth. This paper develops a procedure for analysis of the technique for specific NEOs. First, an optimization method is used to select a proper small body from the database. Some principles of optimality are achieved with the optimization ...

The neomycin phosphotransferase gene (neo) from Transposon Tn5 is active in Gram-negative bacteria but silent in B. subtilis since it lacks an appropriate ribosome binding site for Gram-positive bacteria. Neo translation could be reactivated by coupling its initiation to the translational termination of the highly expressed beta-lactamase gene (penP) from B. licheniformis. This initiation occur...

A high-resolution chemostratigraphic study of a 24-m-thick section at West Blind Fiord on Ellesmere Island (Canadian Arctic) documents stepwise environmental deterioration in the marine Sverdrup Basin during the late Changhsingian (late Late Permian) as a result of volcanic disturbances to surrounding landmasses. A horizon within the upper Lindström Formation (datum A) is characterized by incre...

Galectin inhibitor design is an emerging research field due to the involvement of galectins in cancer. Galectin-3, in particular, plays an important role in tumor progression. To generate inhibitors, modifications of the glycan structure can be introduced. Conjugation of hydrophobic compounds to saccharides has proven to be promising as increased binding of galectin-3 can be observed. In the pr...

In organisms with chromosomal sex determination, sex is determined by a set of dimorphic sex chromosomes that are thought to have evolved from a set of originally homologous chromosomes. The chromosome inherited only through the heterogametic sex (the Y chromosome in the case of male heterogamety) often exhibits loss of genetic activity for most of the genes carried on its homolog and is hence ...

The vitamin A of the euphausiid crustacean, Meganyctiphanes norvegica, consists almost wholly of the hindered cis isomer, neo-b (11-cis). In this animal vitamin A is concentrated almost entirely in the eyes; and its properties so closely resemble those of pure neo-b vitamin A as not in themselves to indicate that any other isomer is present. However, Fisher et al. (1955 b) have isolated a small...

Despite being significantly correlated, there is evidence to suggest that the scales measuring Agreeableness from the Big Five Inventory (BFI) and the Revised NEO Personality Inventory (NEO PI-R) do not capture identical constructs. More specifically, NEO PI-R Agreeableness contains content related to "honesty and humility" that is not contained by the BFI. In a sample of undergraduates (N = 29...
