exposure (Prince, Hargrove, Szmuness, Cherubin, Fontana, and Jeffries, 1970; Papaevangelou, Kourea, and Tsoukas, 1971; Fulford, Dane, Catterall, Woof, and Denning, 1973). A high frequency of HB Ag-positive hepatitis cases was also found among homosexuals (Vahrman, 1973) and evidence has been presented that hepatitis B may spread between sexual partners (Hersh, Melnick, Goyal, and Hollinger, 197...

-A search procedure is developed to find good short binary (N,N 1) convolutional codes. It uses simple rules to discard from the complete ensemble of codes a large fraction whose free distance dfrce either cannot achieve the maximum value or is equal to dfree of some code in the remaining set. Further, the search among the remaining codes is started in a subset in which we expect the possibilit...

The neural crest cells showed a specific sensitivity to mitomycin C, and the neural crest cells in mice treated with mitomycin C were not stained by hematoxylin and eosin. Reports have already been made on the distribution of the neural crest cells in mice embryos of early stage in regard to the characteristics of the staining ability by mitomycin C (Nozue and Kirino 1973 ; Nozue 1973 ; Nozue 1...

The article analyzes the experimental studies of V.P. Demikhov conducted by him in 1968-1973, studying content his report on work done during this period time and presented at Meeting Academic Council N.V.

The presence of phenylethylamine (PEA) in human urine was demonstrated by several investigators (Jepson et al., 1960; Perry, 1962; Oates et al., 1963; Fischer et al., 1968; Boulton and Mil-ward, 1971; Fischer et al., 1972; Mosnaim and Inwang, 1973; Schweitzer et al., 1975). Further, a decrease of PEA was reported in the urine of depressed patients (Fischer et al., 1972; Rodriguez Casanova and F...
