Pharmacokinetics of Metronidazole Administered as a Single Oral Bolus to Red Rat Snakes, Elaphe guttata

Abstract: The pharmacokinetics of metronidazole was evaluated in 16 red rat snakes, Elaphe guttata, after a single oral dose of 50 mg/kg (n=8) or 150 mg/kg (n=8). Blood samples were collected at predetermined intervals over a 48 hr period. Plasma concentrations of metronidazole were measured using high performance liquid chromatography (HPLC). Metronidazole dosed at 50 mg/kg was eliminated with a half-life of 11.1 hr. The apparent volume of distribution (steady state) was 0.053 L/kg, the apparent oral clearance was 3.04 ml/hr, and the mean residence time was 18.5 hr. The plasma concentration of metronidazole exceeded the recommended minimum inhibitory concentration (MIC) in both treatment groups at all time points for at least 48 hr. Based on this study it can be concluded that oral administration of 50 mg/kg of metronidazole to red rat snakes every 48 hr would maintain more than adequate plasma concentrations against susceptible anaerobic bacteria and protozoa.

Galactic Sources Detected in the NuSTAR Serendipitous Survey

Abstract: The Nuclear Spectroscopic Telescope Array (NuSTAR) provides an improvement in sensitivity at energies above 10 keV by two orders of magnitude over non-focusing satellites, making it possible to probe deeper into the Galaxy and universe. Lansbury and collaborators recently completed a catalog of 497 sources serendipitously detected in the 3–24 keV band using 13 deg^2 of NuSTAR coverage. Here, we report on an optical and X-ray study of 16 Galactic sources in the catalog. We identify 8 of them as stars (but some or all could have binary companions), and use information from Gaia to report distances and X-ray luminosities for 3 of them. There are 4 CVs or CV candidates, and we argue that NuSTAR J233426–2343.9 is a relatively strong CV candidate based partly on an X-ray spectrum from XMM-Newton. NuSTAR J092418–3142.2, which is the brightest serendipitous source in the Lansbury catalog, and NuSTAR J073959–3147.8 are low-mass X-ray binary candidates, but it is also possible that these 2 sources are CVs. One of the sources is a known high-mass X-ray binary (HMXB), and NuSTAR J105008–5958.8 is a new HMXB candidate that has strong Balmer emission lines in its optical spectrum and a hard X-ray spectrum. We discuss the implications of finding these HMXBs for the surface density (log N–log S) and luminosity function of Galactic HMXBs. We conclude that with the large fraction of unclassified sources in the Galactic plane detected by NuSTAR in the 8–24 keV band, there could be a significant population of low-luminosity HMXBs.

Application of GIS to a Baseline Survey of Vertebrate Roadkills in Baldwin County, Georgia

Abstract: Physical attributes, traffic volume, and landscape patterns on a particular road are expected to influence the frequency of vertebrate road fatalities. In this study, we surveyed 22.17 km of roadways in Baldwin County, GA, 171 times (3791.1 km total) for vertebrate roadkills over a calendar year. We coded the survey route—consisting of portions of US Highway 441, G A Highway 212, and Meriwether/Lowe Road—for differing habitat types and obstacles along its length, and mapped the spatial data in ArcGIS. We recorded 178 vertebrate roadkills representing 19 species, primarily mammals, with Odocoileus virginianus (White-tailed Deer; n = 46) and Didelphis virginiana (Virginia Opossum; n = 39) most frequently observed. We calculated a roadkill rate of 8.03/km/yr. US 441, which has the most lanes, highest traffic volume, and greatest verge width, had the highest roadkill rate (10.95/km/yr) of the three sections. Seasonal differences in roadkill frequencies for the most commonly observed species appear to...

Recognition of Miconia sect. Sagraeoides (Melastomataceae: Miconieae) and associated nomenclatural changes

Abstract: Recent phylogenetic studies incorporating DNA sequence data have corroborated the suspected non-monophyly of many currently recognized genera of tribe Miconieae (Melastomataceae), which includes about 1800 species restricted to the Neotropics. The genus Mecranium, comprising 24 species endemic to the Greater Antilles and their satellite islands, appears to be a monophyletic exception within the tribe. However, the continued recognition of Mecranium as a genus, at best, would render Miconia paraphyletic. The most practical solution to the problem of non-monophyletic circumscription of genera in the Miconieae is the recognition of a broadly defined Miconia, with the taxonomic recognition of its subclades as subgenera and sections. Here the Mecranium clade is recognized as a section within a broadly circumscribed Miconia, all recognized species are listed, and 26 new names and nomenclatural combinations are published. In addition, the section is described, and the phylogenetic relationships of its species are discussed briefly based on molecular and morphological phylogenetic analyses.

Use of Learning Contracts in a RN-to-BSN Leadership Course.

Abstract: Educating RN-to-BSN students can be challenging and rewarding. The diversity of these students can make designing courses quite difficult. In addition, the RN with experience in nursing practice may resent being put in the traditional role of student. Nominal group process and use of learning contracts in a leadership course in one RN completion program are described as two means of meeting the unique learning preferences of working, adult learners. Houle (1984) identified the learning contract as one means of assisting the adult learner seeking continuing professional education. Accordingly, examples of use of these two strategies in continuing nursing education and staff development are described.
