It is quite intriguing that most virus capsids are either icosahedral or helical in structure. Presumably, these two structures were the ideal structures to protect a viral genome and accessory proteins within a virus particle.elical Capsid. Helical capsids are usually formed from one protein that interlocks to form a helix-like structure around the viral genome. They are usually more common among viruses that infect plants, though influenza, measles, mumps and rabies viruses all have helical capsid structures.
1 RF modulator converts AV to RF channel.  Consumes 9 VDC input voltage and offers Antenna interfaces/ports for reliable transmission.
Radiofrequency Ablation (RFA) of Liver Tumors. Radiofrequency ablation (RFA) is an exciting approach to destroying inoperable primary or metastatic tumors in the liver. With ultrasound guidance, we insert a probe through the liver tissue into the tumor. This probe delivers high frequency alternating electrical current precisely at the site of the tumor.
