A modern day light microscope has evolved from a tool devoted to making primarily empirical observations to what is now a sophisticated , quantitative device that is an integral part of both physical and life science research. Nowadays, microscopes are found in nearly every experimental laboratory. However, despite their prevalent use in capturing and quantifying scientific phenomena, neither a thorough...
One of the most exciting challenges of neurosciences in the last few years is the real-time recording of neuronal activity with single cell resolution across the entire brain. Thanks to the use of optical methods, together with animal models in which the whole encephalon is optically accessible, this goal is getting within reach. In this work, we use a transgenic zebrafish line expressing the genetically...
This experiment was conducted to evaluate the effect of zinc, manganese, and copper sources (inorganic vs. organic) in the diet on laying performance and eggshell quality characteristics. One hundred and eighty Hy-Line W-36 layers at 38 weeks of age were allocated to 36-layer cages of five hens each. Each six cages were randomly assigned to one of the six experimental diets fed from 38 to 53 week...
