The phylogenetic relationships among black-tailed rattlesnakes remain poorly understood and some authors indicated that the diversity of this group has been underestimated additional analyses are required to clarify biogeographic patterns throughout its distribution in Mexico. Therefore, aim study was elucidate across their range, identifying relative divergence times main clades reconstructing...

BACKGROUND Pathophysiology of attention-deficit hyperactivity disorder (ADHD) is not known, and therefore the present study investigated mitochondrial defects, if any in cybrids created from patients and control population. METHODS To investigate mitochondrial pathology in ADHD, cybrids cell lines were created from ADHD probands and controls by fusing their platelets with ρ0-cells prepared fr...

Members of the family Carangidae are top-level predators and highly prized food and sport fishes. Although ecologically and economically important, little is known about the biology of numerous species in the family. This is particularly true of the jacks Caranx ignobilis and C. melampygus, which have experienced recent population reductions around the high Hawaiian Islands due to overfishing. ...
