Cytokine Expression at the Inoculation Site and Nearby Tissues in an Animal Model Infected with Metacyclic Trypomastigotes of Trypanosoma cruzi
Trypanosoma cruzi American trypanosomiasis inoculation site
2010/12/10
Background. Trypanosoma cruzi infection is induced by triatomine contaminated feces containing metacyclic trypomastigotes acquired via small wounds in the skin. Natural unspecific and adaptive humoral...

In conclusion, it could be demonstrated that the developed MBS-model is suitable for simulating ground reaction forces of dogs during walking. In forthcoming investigations the model will be developed...
Risk assessment of re-emerging Plasmodium falciparum on Ishigaki Island using a stochastic transmission model
Plasmodium falciparum Anopheles minimus Ishigaki Island
2010/12/10
On Ishigaki Island, Plasmodium falciparum and Plasmodium vivax epidemics occurred in 1945-1946 and were successfully suppressed. The epidemic re-emerged in 1949 because many settlers immigrated to the...
A Stochastic-Variational Model for Soft Mumford-Shah Segmentation
Stochastic-Variational Model Soft Mumford-Shah Segmentation
2009/9/8
In contemporary image and vision analysis, stochastic approaches demonstrate great flexibility in representing and modeling complex phenomena, while variational-PDE methods gain enormous computational...
The study of cell behavior is of crucial importance in drug and disease research. The fields of bioinformatics and biotechnology rely on the collection, processing, and analysis of huge numbers of bio...
Improving the Accuracy of the Diffusion Model in Highly Absorbing Media
Diffusion Model Highly Absorbing Media
2009/9/7
The diffusion approximation of the Boltzmann transport equation is most commonly used for describing the photon propagation in turbid media. It produces satisfactory results in weakly absorbing and hi...
Anatomical evaluation of CT-MRI combined femoral model
Anatomical evaluation CT-MRI femoral model
2010/2/25
This study revealed that the local 2D contour-based measurement of matching deviation was 0.5 ± 0.3 mm in the femoral condyle, and in the middle femoral shaft. The global 3D contour matching deviation...

Effect of trabecular bone loss on cortical strain rate during impact in an in vitro model of avian femur
trabecular bone loss cortical strain rate avian femur
2010/2/26
We found that removal of core trabecular bone decreased by ~10-fold the cortical strain rate at the side opposite to impact (p < 0.01), i.e. from 359,815 ± 1799 μm/m per second (mean ± standard error)...
