The tropical clawed frog, Xenopus tropicalis, is a relatively new model species being used in developmental biology and amphibian toxicology studies.
Morphometrics permits the rigorous quantitative analysis of variation in organismal size and shape, and is increasingly being used in developmental contexts.
The modern study of dysmorphology is not limited to clinical care, but is used in developmental biology, molecular genetics, and metabolic medicine, where the phenotypic effects of genetic insults engineered in model organisms to parallel the human condition are interpreted in part by observation and measurement of dysmorphic features.
A Northern blot can reliably profile the transcription of miRNAs and has often been used in the analysis of developmental and tissue-specific expression patterns [ 18- 22].
Despite the fact that transient expression analysis has been used in various areas of developmental biology, there has been no report using transient expression analysis for detection of oestrogen compounds.
More recently, the marker of cell division 5-bromo-2'-deoxyuridine (BrdU) has been used in amphioxus to assess developmental cell proliferation, showing that only some regions of the neural plate are BrdU labeled during neurogenesis [ 44].
The term "empathic concern" has been used in a very similar way in developmental and social psychology [4], [5].
A few candidate genes such as dopamine and serotonin genes have been used in hundreds of behavioral studies, including developmental studies, during the past two decades.
We employed the PPVT in this study as it has been used in previous studies on children with developmental disorders, and seems more suitable than the WISC-R for testing children with intellectual disabilities [ 8].
In addition, this species is used in immunology, developmental biology, and biomedical research.
