The level of pyruvate kinase, an autophagic sequestration marker in heavy autolysosomes from E-64-d-treated cells, was much higher in serum-deprived cells, indicating that the contribution of heterophotic sequestration towards an increase in the density of lysosomes is much greater than that of autophagy.

Araliasaponins XII-XVIII, triterpene saponins from the roots of Aralia chinensis.
Seven new oleanane-type saponins, named araliasaponins XII-XVIII, were isolated from the roots of Aralia chinensis, together with 14 known triterpene saponins. On the basis of the chemical and… Expand

1,2,4-Trinitrobenzene (TNB), a novel dinitrophenyl(DNP)ating reagent, was found to react only with SH1 without any other amino acid residues in myosin under the conditions used, and a large red shift of as much as 20 nm was observed compared with low molecular S-DNP derivatives. Expand
Photocross-linking from DNPated SH1 in myosin head. I. Cross-linking to the 50-kDa fragment.
N-Terminal sequence analysis and the amino acid composition of the band revealed that the X-band is an intraheavy chain cross-linking product between the 20- and the 50-kDa fragments, which presents a striking contrast to the other cross- linking from SH1 using benzophenone-4-iodoacetamide. Expand
Quantitative Analysis of Stacking Faults in the Structure of SiC by X-Ray Powder Profile Refinement Method
Submicron powders of SiC were synthesized at different temperatures (1700°-2000°C) by reaction of a mixed powder of carbon and silicon dioxide prepared by the spray thermal decomposition method. The… Expand
Oxidation of coals by nitrate in hot alkaline solutions
In practice, the separation of each benzenecarboxylic acid from the oxidation product or the development of the direct use of the mixture itself is extremely difficult at present. On the other hand,… Expand
Formation Pathway of Oxalic Acid in the Oxidation of Yallourn Coal by Oxygen -Oxidation of Coals in Liquid Phases. VI.-
The oxidation of Yallourn coal (C 66.8%d. a. f.) and the intermediates (water-insoluble acids, water-soluble aromatic acids, and residual coal) was studied as the first s tep for elucidating the… Expand
Oxidation of Coals in Liquid Phases. VII. Oxidation of Oxygen-containing Model Compounds of Coal by Oxygen in Concentrated Sodium Hydroxide Solutions
Oxidation of 26 model compounds of low-ranked coal was performed to study the formation mechanisms of oxalic acid from coal. A mixture of 0.02 mol of the model compound, 4–60 g of NaOH, and 50 g of… Expand
Production of oxalate by the oxidation of coal with oxygen in a concentrated sodium hydroxide solution
Oxidation of coals by oxygen in 25 mol/kg NaOH solution was carried out to examine the effect of coal rank on the production of oxalate. Fourteen coals, ranging from bituminous coal to peat, were… Expand
