Morbidity and mortality in reptiles presented to a wildlife care facility in Central Illinois

We examined morbidity and mortality of 200 reptiles, representing 13 different species that were presented to the University of Illinois Wildlife Medical Clinic (WMC) from 2003 to 2010. Snapping turtles (Chelydra serpentine; n = 46), box turtles (Terrapene sp.; n = 43), painted turtles (Chrysemys picta; n = 37), and red-eared slider turtles (Trachemys scripta elegans; n = 33) were the most frequently seen species. Turtles were significantly more likely to be presented to the WMC following collision with a motor vehicle (n = 73) than any other reason, including idiopathic trauma (i.e., trauma of unknown origin; n = 25) or infectious disease (n =18). The findings from this cross-sectional study suggest a potential for community education in limiting reptile traumas resulting in presentations to a wildlife hospital

Determination of Thiafentanil in Plasma Using LC–MS

A new method of analysis has been developed and validated for the determination of thiafentanil in plasma. After protein precipitation, samples were separated on an XBridge BEH C18 column and quantified using mass spectrometry. The mobile phase was a mixture of water with 0.1% formic acid and acetonitrile with 0.1% formic acid (90:10). The standard curve ranged from 0.1 to 25 ng/mL. Intra- and Inter-assay variability for thiafentanil was less than 10%, and the average recovery was greater than 95%. The lower limit of quantification was 0.1 ng/mL. This is the first validated method for thiafentanil analysis in plasma

Select Metal and Metalloid Surveillance of Free-ranging Eastern Box Turtles from Illinois and Tennessee

The Eastern box turtle has been proposed as a biomonitor because it is long lived, relies on the environment for food and water, and has a small home range. To establish this designation, ISTC partnered with the Illinois Natural History Survey, the College of Veterinary Medicine at the University of Illinois, and the Clinch River Environmental Studies Organization. Plasma samples from 273 free-range box turtles were collected in 2011 and 2012 in Tennessee and Illinois. Full results reported in Allender, Matthew C., et al (2015).

素数集合上の絶対シンプレクティック構造と絶対ワイル代数

The purpose of this paper is to give the absolute mathematics for the prime set. Absolute mathematics was introduced by N.Kurokawa in order to solve the Riemann conjecture. One of the idea for absolute mathematics is the prime differential on the rational integer Z. We analyze all possible arithmetic generalizations of symplectic and contact structures on a prime set. There are two different types of structures according to the Lagrangian subspace and Legendrian subspace. Main result is that the prime set is characterized by the Lagrangian subspace of absolute symplectic space (T*P, w). We also define a notion of the absolute Weyl algebra

Temperature affects the host hematological and cytokine response following experimental ranavirus infection in red-eared sliders (Trachemys scripta elegans).

Pathogen-host interactions are important components of epidemiological research, but are scarcely investigated in chelonians. Red-eared sliders (Trachemys scripta elegans), are recognized as a model for frog virus-3 infection (FV3), a ranavirus in the family Iridoviridae that infects multiple classes of ectothermic vertebrates. Previous challenge studies observed differences in disease outcome based on environmental temperature in this species, but the host response was minimally evaluated. We challenged red-eared sliders with an FV3-like ranavirus at both 28°C and 22°C. We monitored several host response variables for 30 days, including: survival (binary outcome and duration), clinical signs, total and differential leukocytes, and select cytokine transcription in the buffy coat (IL-1β, TNFα, IFYg, IL-10). After 30 days, 17% of challenged turtles survived at 28°C (Median survival time [MST]: 15 days, range: 10-30 days) and 50% survived (MST: 28.5 days, range: 23-30 days) at 22°C (range 23-30 days). The most common clinical signs were injection site swelling, palpebral swelling, and lethargy. The heterophil/lymphocyte ratio at 22°C and interleukin-1 beta (IL1β) transcription at both 22°C and 28°C were significantly greater on days 9, 16, and 23 in FV3 challenged groups. Tumor necrosis factor alpha and interleukin-10 were transcribed at detectable levels, but did not display significant differences in mean relative transcription quantity over time. Overall, evidence indicates an over-robust immune response leading to death in the challenged turtles. FV3 remains a risk for captive and free-ranging chelonian populations, and insight to host/pathogen interaction through this model helps to elucidate the timing and intensity of the host response that contribute to mortality

PLASMA ELECTROPHORETIC PROFILES AND HEMOGLOBIN BINDING PROTEIN REFERENCE INTERVALS IN THE EASTERN BOX TURTLE ( TERRAPENE CAROLINA CAROLINA

Evaluation of plasma electrophoretic profiles and acute phase protein concentrations may play a valuable role in health assessment of reptiles; however, little is known about reference intervals in free-ranging eastern box turtles (Terrapene carolina carolina). The purpose of this study was to establish reference intervals of protein electrophoretic profiles and hemoglobin binding protein ([HBP] as determined by a haptoglobin assay) in free-ranging eastern box turtles and to assess any possible correlations between varying age class (adults vs. juvenile), sex (male, female, or unknown), season (spring, summer, or fall), or location (Tennessee vs. Illinois). Blood samples were obtained from 324 eastern box turtles from 2010 to 2012 at three sites in Illinois and one site in Tennessee, USA. Significant differences were observed with total protein (sex, season, state, Illinois location), albumin (age class, season, state, Illinois location), α-1 globulins (sex, season, Illinois location), α-2 globulins (sex, season, state, Illinois location), β globulins (age class, sex, season, state, Illinois location), γ globulins (sex, season state, Illinois location), and hemoglobin binding protein (age class, sex, state, Illinois location). The use of electrophoretic profiles and acute phase proteins is a relatively new concept in reptilian medicine, and this study allowed for establishment of references intervals in the eastern box turtle and emphasized differences that occured based on age, sex, season, and location. Future research in this area can now build on these data to determine changes in population health over time or alterations due to specific environmental or disease threats
