Zebrafish models in translational research: tipping the scales toward advancements in human health
Advances in genomics and next-generation sequencing have provided clinical researchers with unprecedented opportunities to understand the molecular basis of human genetic disorders. This abundance of information places new requirements on traditional disease models, which have the potential to be used to confirm newly identified pathogenic mutations and test the efficacy of emerging therapies. ...
متن کاملTipping the balance toward trophoblast development.
Understanding the development of the human trophoblast lineage and placentation is a challenge. Ethical issues prevent the most direct experimentation. Animal models have provided considerable insight, but species differences exist and knowledge of key regulatory events in human development is missing, which precludes an appreciation of conserved processes. In the mouse, it is possible to captu...
متن کاملEvaluating Total Mercury and Methyl Mercury Contents in Canned Tuna Fish of the Persian Gulf
Due to hygienic risks of mercury residues in food and marine originated supplements, measuring total mercury and methyl mercury contents of canned tuna as a highly consumable marine food product is essential. In this study, 40 canned Tuna fish (from Persian Gulf) were collected in 2015 and then flame atomic absorption spectrometer (FAAS) and thermo gas chromatography mass spectrophotometry were...
متن کاملTipping the scales: auditory cue weighting changes over development.
How does auditory processing change over development? This study assessed preschoolers' and adults' sensitivity to pitch contour, pitch height, and timbre in an association-memory paradigm, with both explicit (overt recognition) and implicit measures (visual fixations to melody-linked objects). In the first 2 experiments, child and adult participants associated each of 2 melodies with a cartoon...
متن کاملTipping the scales: guidance and intrinsically motivated behavior
We propose a novel approach to learning in autonomous robots that relies on the dynamical maintenance of an actively sensitized sensorimotor loop. Very weak learning cues are sufficient to orient a robot towards the desired behavior which is then selected from the intrinsic exploratory movements rather than imposed by a control command. The learning paradigm is a form of guided self-organizatio...
