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.

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.
