In Belgium, case of new coronavirus, severe acute respiratory syndrome coronavirus 2 SARS CoV 2 infection from owner to domestic cat was reported on March 27, 2020. So far, cases of SARS CoV 2 infection from owners to their dogs have been reported. For the first time in the world, the case of SARS CoV 2 transmission from the owner to a domestic cat has been confirmed. A tiger kept at a zoo in New York, USA, was reportedly infected with SRAS CoV 2. It is believed that SRAS CoV 2 has been transmitted to tiger from caretakers infected with SRAS CoV 2. Therefore, we examined the homology of whole molecule and the 5 amino acids residues KGDFR located in the binding region of the angiotensin converting enzyme 2 ACE2 molecule, a receptor for the spike glycoprotein on the virion surface of SRAS CoV 2, between humans, dogs, cats, tiger and other mammals. Although the transmission of human coronavirus to pets or animals is rare, the dangers of transmitting SARS CoV 2 from animals or pets to humans have not been proven. Our findings with Shi's study provide important insights into the animal models for SARS CoV 2 and animal management for COVID 19 control. 

Patients diagnosed with localized prostate cancer have many curative treatment options including several forms of advanced conformal Radiotherapy. Proton radiation is one such radiation treatment modality and, due to its unique physical properties, offers the appealing potential of reduced side effects without sacrificing cancer control. Patients of proton beam therapy PBT for prostate cancer had been continuously growing in number due to its promising characteristics of high dose distribution in the tumor target and a sharp distal fall-off. While theoretically beneficial, its clinical values are still being demonstrated from the increasing number of patients treated with proton therapy, from several dozen proton therapy centers around the world. High equipment and facility costs are often the major obstacle for its wider adoption. The picture will be clearer in coming decade as more and more centers throughout the world avail access to this technique and more data emerges on PBT.
