The relationship between serum tumor-associated trypsin inhibitor levels and clinicopathological parameters in patients with gastric cancer

BACKGROUND: Tumor-associated trypsin inhibitor (TATI) is expressed with trypsinogen in tumors. We studied the clinical-pathologic association and significance of preoperative serum levels of TATI in gastric cancer patients

Yttria Stabilized Zirconia (YSZ) Crystallization in Al2O3/YSZ Multilayer

Yttria-stabilized zirconia (YSZ)/Al2O3 multilayers deposited on Pt foil were studied by differential scanning calorimetry. Observed thermal effects were interpreted using additional evidence from x-ray diffraction and transmission electron microscopy. The crystallization temperature of YSZ increases from 344 to 404 degrees C as the layer thickness decreases from 15 to 4 nm. The enthalpy of crystallization becomes more exothermic with decreasing thickness, and it was measured to be -26 kJ/mol YSZ for 4-nm-thick layers and -12 kJ/mol for 15-nm-thick layers. The latter value is consistent with the reported crystallization enthalpy for YSZ powder of the same composition prepared by precipitation from aqueous solution. The more exothermic crystallization enthalpies for thinner films are indicative of a decrease in their degree of crystallinity. The 2-6-nm-thick Al2O3 layers remain amorphous when heated to 1000 degrees C. The described methodology enables thermal analysis of oxide thin films using commercial instruments

Strain engineering to control the magnetic and magnetotransport properties of La0.67Sr0.33MnO3 thin films

This work studies the control of the magnetic and magnetotransport properties of La{sub 0.67}Sr{sub 0.33}MnO{sub 3} thin films through strain engineering. The strain state is characterized by the tetragonal distortion (c/a ratio), which can be varied continuously between a compressive strain of 1.005 to a tensile strain of 0.952 by changing the type of substrate, the growth rate, and the presence of an underlying La{sub 0.67}Sr{sub 0.33}FeO{sub 3} buffer layer. Increasing tensile tetragonal distortion of the La{sub 0.67}Sr{sub 0.33}MnO{sub 3} thin film decreases the saturation magnetization, changes the temperature dependence of the resistivity and magnetoresistance, and increases the resistivity by several orders of magnitude
