Also, they determined that when the spleen reached or extended below the lower third of the left kidney, this was highly specific for splenomegaly despite a low sensitivity (sensitivity 20%, specificity 93%). The study validated the use of a simple splenic length measurement for splenic CT volume. When splenic length exceeds 10 cm, a diagnosis of splenomegaly should be made. This clinically practical, accurate, simple measurement replaces multiple-measurement, time-consuming methods, and allows daily routine follow-up, the authors reported.
1 This volume will in addition discuss RNA viruses and bring a historical perspective of where studies began to a more recent molecular approach and vaccine successes in tumor viruses.  This volume will also cover other known oncogenic viruses associated cancers in other mammals in addition to humans.
A virus that uses the lysogenic life cycle is termed either a provirus or prophage. What causes various proviruses to shift to the lytic cycle is not completely understood, but in some cases stress is the stimulus.These are newly discovered particles of RNA that are known to attack plants, at this point.his theory states that 15% of cancers are caused by viruses. One example is HPV, which causes cervical cancer i.e. cancer of the cervix in women. The virus is lysogenic and it inserts a destructive gene into the tumor suppressor T53 gene. This allows a mutated oncogene to cause a cell to become cancerous.
