Background High dose chemotherapy is one of the therapeutic strategies for breast cancer and doxorubicin (DOX) as a chemotherapy agent is widely used. DOX indication is limited due to its dose‐depended cardiotoxicity. Recently, cannabidiol (CBD) shows antitumoral and cardioprotective effects, so we hypothesized that CBD administration with high‐dos...

Question
after 7 days 80% of our animals show tumor growth. I wonder for that 20% what should we do? does it need more time? Or second injection? or we should put them out of the experiment?
Question
I have 5 groups (n=8), and the values in each group are same so that the mean of each group is the same as the data in that group and the error amount is zero. now I want to compare these five groups. Which test would be the best choice?
Question
Our power supply for western blotting transfer process needs three parameters of watt, voltage and current. In LC3 western blotting in different methods just the voltage or just the current are indicated and so I do not know how I can adjust these three to get the best results
Question
With human kits is referenced but they don't work in rat hearts.
