Primary spinal primitive neuroectodermal tumors (PNETs) are rare tumors. Most of these tumors occur in children and young adults. To date, 47 cases of primary spinal PNET have been reported in the literature. These tumors are highly aggressive with rapid growth. Review of the literature shows that the overall prognosis of PNETs of spinal cord is very poor(More)
We used random amplification of polymorphic DNA (RAPD) to generate species-specific diagnostic fragment patterns for the molecular identification of the ornamental aquarium fish species Badis badis and Dario dario. Seven arbitrary oligodecamer primers produced a total of 116 bands of which 98.23% were polymorphic. The size of the amplified products was in(More)
