Effects of yessotoxin (YTX) on the skeletal muscle: an update.

Yessotoxins (YTXs) are algal toxins originally included in the diarrheic toxins. After oral intake, YTXs induce only ultra-structural changes (packages of swollen mitochondria) in cardiac cells. The aim of this study was to investigate the possible effects of YTX on the other contractile striated tissue, the skeletal muscle, in vitro and in vivo.

Low levels of genetic divergence across geographically and linguistically diverse populations from India.

Ongoing modernization in India has elevated the prevalence of many complex genetic diseases associated with a western lifestyle and diet to near-epidemic proportions. However, although India comprises more than one sixth of the world's human population, it has largely been omitted from genomic surveys that provide the backdrop for association studies of genetic disease. Here, by genotyping India-born individuals sampled in the United States, we carry out an extensive study of Indian genetic variation.

A new locus for autosomal dominant amelogenesis imperfecta on chromosome 8q24.3.

Amelogenesis imperfecta (AI) is a collective term used to describe phenotypically diverse forms of defective tooth enamel development. AI has been reported to exhibit a variety of inheritance patterns, and several loci have been identified that are associated with AI. We have performed a genome-wide scan in a large Brazilian family segregating an autosomal dominant form of AI and mapped a novel locus to 8q24.
