    Notes: Summary The accelerated transport of the blood neutral amino acids into the brain in encephalopathic patients with fulminant hepatitis and advanced liver cirrhosis was demonstrated not only by determining the cerebrospinal fluid (CSF) aminogram but also by calculating the predicted velocity of the amino acid transport through the blood-brain barrier. Significant elevation in CSF aromatic amino acid (AAA) and methionine levels was observed in the encephalopathic patients. Arousal from hepatic encephalopathy by drip infusion of a branched chain amino acid (BCAA)-enriched solution was obtained coincidentally with the elevated BCAA levels and diminished concentrations of AAA and methionine in CSF. These clinical observations were confirmed experimentally in rats treated with carbon tetrachloride (CCl4) andd-galactosamine by obtaining the elevation of neutral amino acid contents in the brain and the slight increase in the brain uptake index (BUI) of a radiolabeled amino acid.

    Notes: Abstract The alloying behavior of antimony atoms into nm-sized indium clusters has been studied in situ by TEM. When antimony atoms are vapor-deposited onto nm-sized indium clusters, a rapid dissolution of antimony atoms into indium clusters takes place and as a result InSb compound clusters are successfully formed. Such spontaneous alloying occurs even at ambient temperature. InSb clusters thus formed have the wurtzite structure. When these InSb clusters are annealed at 533 K, their structure changes into the sphalerite structure, which is the structure of the equilibrium phase of the bulk In50Sb50. The appearance of wurtzite-type InSb by spontaneous alloying is discussed in terms of ionicity of bonds in InSb.
