    Effects of gas flame annealing on the structure of poly-Si films (1995)

    Notes: The effect of gas flame annealing on the structure of polycrystalline Si films was studied using transmission electron microscopy and electron spin resonance. This annealing technique involved heating the sample surface to more than 1100 °C using flat gas flames with a scan rate of 1 mm/s and a heating rate of about 260 °C/min. Electron microscopy images revealed that the secondary grain growth proceeded with increasing the number of annealing times (annealing frequency) and that the grain size for samples annealed at 1360 °C was more than 1 μm whereas secondary grain growth was not significant for samples annealed at 1150 °C. Further, it was found that the spin density in the samples annealed at 1360 °C decreased from 1.5×1018 cm−3 to 3.8×1017 cm−3. It was concluded from the spin resonance results and the electron microscopy images that the secondary grain growth consists of two processes, the initial structural rearrangement of the grain boundaries and the subsequent grain growth. © 1995 American Institute of Physics.

    Notes: —Methods for the determination of methyl-lysine, methyllarginine and methylhistidine residues of tissue proteins are described. They consist of preliminary purification of basic amino acids, enzymic removal of lysine, arginine and histidine followed by amino acid analysis. Recovery rates and specificities of the method were satisfactory. The contents of methylamino acids in proteins of mammalian organs were determined.The distribution of proteins containing the methylamino acids in human brain showed that the concentrations of methyl-lysine and NG,N′G-dimethylarginine were highest in the gray matter of the cerebellar cortex and relatively high in regions rich in gray matter, while those of NG-mono- and NG,N′G-dimethylarginine were highest in the white matter. The following findings suggest that most of the NG-mono- and NG,N′G-dimethylarginine was associated with the myelin basic protein. The distribution of the methylarginine residues of acid-soluble proteins in bovine brains coincided with the cerebroside pattern. The concentrations of the amino acids in acid-soluble proteins of rat brain increased concomitantly with the increase of cerebroside. The methylamino acid content in proteins increased during the purification of the myelin basic protein from the white matter of human and bovine brains.Proteins containing NG,NG-dimethyiarginine and di- and trimethyl-lysine are concentrated in cell nuclei. The first amino acid was found mainly in nucleoplasmic proteins and the other two were found in histones. The concentration of 3-methylhistidine residue, highest in muscular proteins, is low in cerebral proteins and is probably derived from proteins of walls of blood vessels in the brain.

    PROTEIN METHYLATION BY CEREBRAL TISSUE (1973)

    Notes: Abstract— Transfer of the methyl group of S-adenosyl [Me-14C]methionine into cerebral proteins, an encephalitogenic protein and histones was studied using extracts of bovine and rat brains. The brain extract contains multiple substrate proteins and their lysine and arginine residues were methylated to form Ne-mono-, -di- and -trimethyl-lysine and NG-mono-, NG, NG- and NG,NG-dimethylarginine residues respectively, at different rates. The enzyme which catalyses the methylation of arginine residues was differentiated by ammonium sulphate fractionation from that methylating lysine residues. Methylation of arginine and lysine residues of proteins was stepwise in general, from mono- to dimethyl-arginine and from mono- to di- and trimethyl-lysines. Two different enzymes which methylate histone and the encephalitogenic basic protein respectively were obtained from the cytoplasmic fraction of rat brain and their enzymic properties were examined.

    OCCURRENCE AND FORMATION OF γ-GLUTAMYLPUTRESCINE IN MAMMALIAN BRAIN (1976)

    Notes: —An unknown radioactive compound was detected in the basic fraction of the trichloroacetic acid extract of rat brain injected with radioactive putrescine. This compound was purified from bovine brain and identified as γ-glutamylputrescine by comparison of its behaviour with that of the synthesized glutamylamides. The amide seemed to be metabolized as rapidly as putrescine in rat brain.

    Notes: Abstract– γ-Glutamyl amides of histamine, serotonin and dopamine were formed from these amines by the transfer of the γ-glutamyl moiety from γ-glutamyl peptides in the presence of γ-glutamyl transpeptidase. [I4C]Histamine was injected intraventricular into rats, and the formation of γ-glutamyl-[14C] histamine in the brain was confirmed by purification and identification with the authentic compound. The radioactivity was highest 30 min after the injection. The possible significance of γ-glutamyl amides in nerve transmission is discussed.
