Habitat Use and Thermal Ecology of Ratsnakes (Elaphe Obsoleta) and Racers (Coluber Constrictor) in Illinois
… demands (ratsnakes and racers [ Coluber constrictor]) at the same Illinois location. I also examine the interdependence of habitat use (especially forest edges) and thermoregulatory behavior. Within populations, I examine the effects of season and sex on habitat use and thermal ecology. I …

Rapid and portable molecular detection tools for reptile pest priority species in Australian environmental biosecurity scenarios
… high-risk terrestrial reptiles: common boa (Boa constrictor), and the American corn snake (Pantherophis guttatus). Predicted consequences of their introduction, establishment and spread are dire for Australian biodiversity outcomes due to their broad climate tolerance, generalist ecology, and …

Angiogenesis and Myogenesis in a Chronic Ischemic Heart.
… three surgical procedures: (1) placing a constrictor on the coronary artery; (2) producing channels and implanting cells; (3) obtaining samples. The swine were divided into groups: Group 1, Ischemia; Group 2, Ischemia + Laser TMR; Group 3, Ischemia + Laser TMR+ Cells; Group 4, Ischemia + …

Habitat Use And Seasonal Activity Of Selected Snakes On John F. Kenned
… three most commonly captured species, Coluber constrictor, Thamnophis sirtalis, and Thamnophis sauritus, combined made up 85% of the sample. These three species were active during every month of the year, but showed modal activity patterns typical of Temperate Zone snakes. Monthly snake …

Evolution of the Jaw Apparatus in Pythons
… apparatus in seven species of pythons and Boa constrictor reveals that variation in these data was largely size-related (variation along PC1 = 95.0%) and species discrimination was limited due to confounding within- and among-species size effects. Discriminant function analysis of …

Simulation and design of a hydrogen arcjet thruster seeded with cesium
… cesium is fairly uniformly spread throughout the constrictor, as is the current density, so there is no formation of a narrow arc as in conventional thrusters.

Use of a piezoelectric actuator to study the mechanical oscillatory behavior of living cells
… in the cell was altered by addition of the constrictor agent, thrombin. The results showed that the experimental method is effeqtive for determining the effects of chemical disruptors on the mechanical oscillatory behavior of cells. Specifically, in the presence of nocodazole, absolute …

Ecology of Upland Snake Communities in Managed Montane Longleaf Pine Habitats of Georgia
… trapped species: Black racers (<em>Coluber constrictor</em>), copperheads (<em>Agkistrodon contortrix</em>), corn snakes (<em>Pantherophis guttatus</em>), Eastern hognose (<em>Heterodon platirhinos</em>), and timber rattlesnakes (<em>Crotalus horridus</em>). Northern pine snake …

The development and operating characteristics of an improved plasma torch for supersonic combustion applications
… in the low pressure region, downstream of the constrictor. This lowers the heat flux to the anode, so that erosion is decreased. The torch body was redesigned with an emphasis on the alignment of the electrodes. Also, the electrode gap in the improved torch was made continuously adjustable, …

A Study of Plasma Ignition Enhancement for Aeroramp Injectors in Supersonic Combustion Applications
… of the anode revealed that anodes with short constrictor lengths and sonic exit nozzles provided superior ignition performance based on higher transfer rates of thermal energy from the arc to the feedstock. This resulted in the production of higher hydrogen atom concentrations within the …

Preeclampsia Link to Gestational Hypoxia
… imbalance in maternal plasma, increased constrictor reactivity in isolated uterine and femoral arteries, impaired glomerular ultrafiltration, increased uterine artery pulsatility and a reduced ontogenic fall in uterine vascular resistance and in arterial blood pressure with advancing …

Analisis kondisi dan potensi lama fermentasi medium kombucha (teh, kopi, rosela) dalam menghambat pertumbuhan bakteri patogen (Vibrio cholerae dan Bacillus cereus)
… dalam air, selain itu kombucha juga bersifat constrictor (pengerut) lipofilik yang dapat bersifat toksik bagi mikroba patogen. Penelitian ini bertujuan untuk menganalisis kondisi dan potensi medium kombucha (teh, kopi, rosela) dalam menghambat pertumbuhan bakteri patogen (Vibrio cholerae dan …

Sex differences in aortic endothelial function of diabetic rats: Possible involvement of superoxide and nitric oxide production
… (100 μM), a NADPH oxidase (Nox) inhibitor. Constrictor response curves (CRC) to PE (10 -8 to 10 -5 M) were also generated before and after pretreatment with L-NAME (200 μM), an endothelial nitric oxide synthase (eNOS) inhibitor, in the presence of indomethacin. In addition, the level of Nox …

Adjustierbarer Gefäßkonstriktor
Bei erwachsenen Patienten nach einer Vorhofumkehroperation als Palliation einer d-Transposition der großen Arterien ist die Prognose angesichts der zunehmenden Insuffizienz des rechten Ventrikels als Systemventrikel ab der zweiten Lebensdekade erheblich eingeschränkt. Um diese Patienten …

Vascular Kv7 (KCNQ) Potassium Channels As Therapeutic Targets in Cerebral Vasospasm
… that arginine8-vasopressin exerts its vasoconstrictor effects on mesenteric arteries via suppression of Kv7 currents. Hence, we hypothesized that suppression of Kv7 currents by spasmogens is a central phenomenon in the pathogenesis of cerebral vasospasm and that Kv7 channel openers would be …

Snakes as predators of bird nests: now and in a warming world
… [Elaphe obsoleta] and black racer [Coluber constrictor]) to better understand: 1) what factors influence nest predation rates by these two snakes, 2) which sensory mechanisms snakes use to locate prey, 3) how snake activity patterns vary with temperature, and finally, 4) how nest predation …
