A Simple ImageJ-Based Method to Measure Cardiac Rhythm in Zebrafish Embryos

The controllability of cardiac rhythm in elderly

Introduction: Recent reports have shown that rare fluctuations in cardiac cycles are ‘forgotten’ quickly in healthy individuals and it is possible to quantify the “memory length” of a physiological time-series using an inverse statistical approach. Methods: In the present study, we assessed the effect of aging on memory length in cardiac rhythm. Results: There was a long...

A Simple Method to Improve Hazelnut Grafting

Hazelnuts are usually propagated by suckers or layering. However, other methods of propagation have been tested with variable results. Grafting is a method that has a few advantages such as fast multiplication rate, earlier fruiting and reducing sucker removal cost on specific rootstocks. Unfortunately, grafting is difficult due to slow formation of callus in hazelnuts. Here, we report the hypo...

A Simple Method for Freezing Bovine Embryos

osteoclast-like cells in early zebrafish embryos

objective: genes involved in bone and tissue remodelling in the vertebrates include matrix metalloproteinase-9 (mmp-9), receptor activator of necrosis factor κ-β (rank), cathepsin-k (ctsk) and tartrate-resistant acid phosphatase (tracp). we examine whether these markers are expressed in cells of zebrafish embryos of 1-5 days post fertilization. we also examine adult scales, which are known to c...
