This study attempts to clarify the link between the pattern of drug abuse and seroprevalence for human immunodeficiency virus (HIV) among volunteers attending a detoxification clinic in(More)
To elucidate the forees maintaining protein polymorphisms, microgeographic differentiation in proteins, encoded by 30 loci, was tested in 285 individuals comprising 3 species of landsnails in Israel. Each test consisted of 2 close subpopulations: one from the drier and warmer south-facing slope and the other from the opposite wetter and cooler north-facing(More)
Allozymic variation in proteins encoded by 20 loci was analyzed electrophoretically in 126 adult specimens representing 4 populations and 2 species of the desert landsnail Trochoidea, subgenus Xerocrassa, in a variable desert climatic back-ground of temperature and water factors. In addition, geographic variation in 3 morphological body variables of these(More)
