Sodium dichloroacetate(DcA) has been studied as a metabolic cancer therapy since 2007, based on a publication from Bonnet et al demonstrating that DcA can induce apoptosis(programmed cell death) in human breast, lung and brain cancer cells. classically, the response of cancer to a medical therapy in human research is measured by Response Evaluation criterial for Solid Tumours definitions, which define "response" by the degree of tumour reduction, or tumour disappearance on imaging, however disease stabilization is also a beneficial clinical outcome. It has been shown that DcA can function as a cytostatic agent in vitro and in vivo, without causing apoptosis. A case of a 32-year-old male is presented in which DcA therapy, with no concurrent conventional therapy, resulted in regression and stabilization of recurrent metastatic melanoma for over 4 years' duration, with trivial side effects. This case demonstrates that DcA can be used to reduce disease volume and maintain longterm stability in patients with advanced melanoma.

Forty-five acid sulfatc topsoil samples (depth coreswere collected from 11 locations along the New South Wales coast, Australia. There was an overalltrend for the concentration of the Hcl-extractable P to increase along with increasing amounts oforganic c and the Hcl-extractable trivalent metals in the topsoils of some less-disturbed acidsulfate soils (pH c P in these soils probably accumulated viabiological cycling and was retained by complexation with trivalent metals or their oxides andhydroxides. While there was no clear correlation between pH and the water-extractable P, theconcentration of the water-extractable P tended to increase with increasing amounts of theHcl-extractable P. This disagrees with some established models which suggest that the concentrationof solution P in acid soils is independent of total P and decreases with increasing acidity. Thehigh concentration of sulfate present in acid sulfate soils appeared to affect the chemical behaviorof P in these soil systems. comparison was made between a less disturbed wetland acid sulfate soiland a more intensively disturbed sugarcane acid sulfate soil. The results show that reclamation ofwetland acid sulfate soils for sugarcane production caused a significant decrease in theHcl-extractable P in the topsoil layer as a result of the reduced bio-cycling of phosphorusfollowing sugarcane farming. Simulation experiment shows that addition of hydrated lime had noeffects on the immobilization of retained P in an acid sulfate soil sample within a pH range3.5～4.6. When the pH was raised to above 4.6, soluble P in the soil extracts had a tendency toincrease with increasing pH until the 15th extraction (pH 5.13). This, in combination with the poorpH-soluble P relationship observed from the less-disturbed acid sulfate soils, suggests that solubleP was not clearly pH-dependent in acid sulfate soils with pH < 4.5.

The steady state creep rate equdtion of a nickel base superalloy Inconel 718, strengthened by coherent ordered disc-shaped bct γ^(11) phase and coherent spherical fcc γ~1 phase precipitates, has been established in the stress and temperature ranges of 620-840 MN m^(-2) and 853-943K, respecti- vely. constant stress tensile creep tests were used to medsure the values of steady state creep rate, ε_s, and the consecutive stress reduction method was used to measure the back stress during creep deformation. The values of effective stress exponent, n_e, were detemined from the slopes of the lgε_s vs. lg(σ_a-σ_0)/G plots. The effect of grain size, d, on steady state creep rdte has been also studied in this investigation, and the grain size sensitive exponents m were detemined from the slopes of lgε_s vs. lg(b/d) plots. The creep rate equations of Inconel 718, in the above stress and temperature ranges, have been proposed to be ε_s=1.6×10^(-5)(D_1Gb/KT) (b/d )^(0.19)[(σ_a-σ_0)/G]^(1.35) in diffusional creep region, and ε_s =75(D_1Gb/KT) (b/d)^(-0.42)[(σ_a-σ_0)/G]^(5.5) in dislocation power law creep region.
