As he follows the path of this mysterious animal, Walker interweaves the tales of the adventurers, scientists, and warriors who've come below the thrall of the beast, and the way their activities could form the destiny of the enormous sable antelope and the background of the war-torn state that's its merely domestic.

Other findings. In a twins sample of 11 monozygotic and for schizophrenia discordant pairs done by Pollin et al. (1966), a clinically relevant thyroid disorder was found with unexpected frequency among the mothers (7 of 11 mothers). Since the husbands of these women had no thyroid problems, geographical artifacts were rather unlikely. Goldberg et al. (1990) conducted a series of neuropsychological tests with 16 monozygotic pairs discordant for schizophrenia. The schizophrenic twins showed deficiencies, especially in the vigilance and memory test results, as well as in the forming of concepts compared to the healthy co-twins.
Concordance group Cl. The co-twin is/was also psychotic and show/showed a psychopathological cross-sectional picture with consideration of the course of the illness, requiring assignment to the same diagnostic main category of 3 - 5 to which the indextwin had been classified. Concordance group C2. The co-twin suffers/suffered from another psychosis of the schizophrenic spectrum. Concordance group C3. The co-twin does not/did not suffer from a schizophrenic spectrum psychosis (in this case: cycloid psychosis, unsystematic or systematic schizophrenias), but does exhibit another relevant psychiatric disorder, except a demential disorder or a mental retardation.
01) intrapair-correlation of the MAO activity was found. Discordance for schizophrenia as well as medication (neuroleptics in the case of the schizophrenic index-twin vs. no medication in the case of the healthy co-twin) had no essential influence on the activity of the MAO. There was no intrapair-correlation with the dizygotic twins. e. both the ill and the healthy twin), both compared with the entire group of control persons (n = 60) as well as with every individual group of control persons. g.
