This paper reviewed the chromosomal engineering in the aspects of double diploid, hetero-additive line, hetero-replacement line, exchange line, monosome one incomplete chromosome systems.
Conclusion:The early operation should be administered when the burst fracture complicated with incomplete neurotmesis happens in the segment of thoracic and lumbar vertebrae.
Injury by forceps holder is secondary, but incomplete or complete neurotmesis is rare.Open reduction is beneficial for anatomical reduction and recovery of nerve injury.
The second-order NLO properties of a series of tri-nuclear transition metal clusters with incomplete cubane-like structures were studied by using the first-principle quantum chemical method.
Results Based on the extent, the injury was classified as concussion and hydropsia, contusion and hemorrhage, compress and twist, complete or incomplete transsection of spinal cord.
