Method Female SD rats received intra-tibial injection of syngenetic Walker256 mammary gland carcinoma cells in different concertration(103/μl,104/μl or 105/μl). Pain threshold of mechanical hyperalgesia and thermal hyperalgesia were tested at 1d,3d,5d,7d,10d,and 14d after cell injection.
Changes of pain behavior were assessed by withdrawal threshold of the hindpaw to von Frey filament stimulation intensity, withdrawal latency of the hindpaw to radiant thermal and a cumulative pain scores before incision as well as 2h, 3h ,6h, 1d, 2d, 3d, 5d after incision.
Heating cells or organisms generates the expression of a class of proteins , knows as heat shock proteins (HSP). The response and the protein structure are universal, having been found in all organisms from bacteria to humans. The HSR has important protective effects.
Methods Rabbit brain tissue is treated by a radiofrequency hyperthermia generator with given heating time and vary probe temperature, the radius of lesions are measured and rabbit brain are examined pathologicaly by HE, TUNEL, or TEM.
By using heating plate to heat the citric acid buffer to retrieve antigens in formalin-fixed,paraffin-embedded sections and by immunohistochemical ABC method,we examined the expression of Ki-67 in 34 cases of osteosarcoma. The results showed that the cell proliferative rates were from 7.5% to 32.0%,with an average of 18.1%.
Conclusion: It is optimal to use 70～80 ℃ and 20 seconds as heating parameters in radiofrequency lesion, and the influence of heating on surrounding brain structure is very limited within these parameters.
As applications, the wave equation on?+ × ?+ and the heat equation in a semi-infinite rod are considered in detail.
In a much cited article, Yau  proved that when the Ricci curvature is bounded uniformly below, then the only bounded solution to the heat equation ?tμ=Δμ on [0, ∞) × M which vanishes at t=0 is the one which vanishes evarywhere.
Well-posedness of a semilinear heat equation with weak initial data
In the first part the initial value problem (IVP) of the semilinear heat equation with initial data in is studied.
For the analogs of the heat and wave equation, we give algorithms for approximating the solution, and display the results of implementing these algorithms.
The nonlinear PDEs consist of a heat equation with the Joule heating as a source and a current conservation equation with temperature-dependent electrical conductivity.
In order to get these second-order error estimates, the Joule heating source is used in a changed equivalent form.
There were different TG curves for unprepared and calcined Magnetitum (Cishi) samples on heating.
Compound 3 exhibited the enchased texture of a smectic liquid crystal from 209.4°C to 219.5°C on heating, while 2 exhibited a liquid crystalline phase from 87.4 to 83.2°C on cooling.
In particular, the differential thermal analysis curves for the decomposition of CeO2 nanocrystalline precursor were measured at different heating rates in air by a thermal analyzer (NETZSCH STA 449C, Germany).
