Genetic influences on brain structure

Nature Neuroscience, 2001
Here we report on detailed three-dimensional maps revealing how brain structure is influenced by individual genetic differences. A genetic continuum was detected in which brain structure was increasingly similar in subjects with increasing genetic affinity.

Aminopropyltransferases: Function, Structure and Genetics

The Journal of Biochemistry, 2006
Aminopropyltransferases use decarboxylated S-adenosylmethionine as an aminopropyl donor and an amine acceptor to form polyamines. This review covers their structure, mechanism of action, inhibition, regulation and function. The best known aminopropyltransferases are spermidine synthase and spermine synthase but other members of this family including an

Isozymes, plant population genetic structure and genetic conservation

Theoretical and Applied Genetics, 1978
The exploration, conservation and use of the genetic resources of plants is a contemporary issue which requires a multidisciplinary approach. Here the role of population genetic data, particularly those derived from electrophoretic analysis of protein variation, is reviewed. Measures of the geographic structure of genetic variation are used to check on

Genetic structure of Algerian populations

American Journal of Human Biology, 2006
AbstractBlood samples were collected in Algeria from 4,444 army recruits and tested for 10 genetic polymorphic systems. These samples were collected from territorial Wilayas (administrative units of Algeria) from which the young soldiers had originated.

Laminins: Structure and genetic regulation

Microscopy Research and Technique, 2000
The laminins form a large family of modular proteins found in basement membranes, but also elsewhere. They function as structural components and are essential for morphogenesis, but in addition interact with cell surface receptors such as integrins and alpha-dystroglycan.

GENE DISPERSAL AND SPATIAL GENETIC STRUCTURE

Evolution, 1997
Spatial autocorrelation statistics have been studied in theoretical population genetic models and widely used in experimental studies of spatial structure in many plant and animal populations. However, the statistical properties of spatial autocorrelation statistics have remained uncharacterized.

Genetic structure of human populations

Journal of Toxicology and Environmental Health, 1979
The difficulty of extrapolating from inbred mouse strains used for the assessment of toxicological responses to the human population that may be exposed to the potentially toxic substance is discussed. Conventional risk estimation procedures assume little heterogeneity among members of the population in their response to a substance.

Structure and Comparison of Genetic Theories: (I) Classical Genetics

The British Journal for the Philosophy of Science, 1986
It is the purpose of this and the following two papers to make an attempt to reconstruct Mendelian genetics using the method of set-theoretic predicates. The use of informal set-theoretic predicates for reconstruction of empirical theories goes back to \textit{P. Suppes} [Set- theoretic structures in science.

Genetic structure of southwestern Corsica (France)

American Journal of Human Biology, 1998
The distribution of nine red cell enzymes (ACP, ADA, AK, DIA, ESD, GLO1, PGM1, PGD, and SOD) and seven plasma proteins (C3, GC, HP, ORM, PI, PLG, and TF) was analyzed in a sample of 274 unrelated individuals from the southwestern area of Corsica (France), specifically from Ajaccio and nearby villages.
