Because of AAV's specialized gene therapy advantages, researchers have created an altered version of AAV termed self-complementary adeno-associated virus (scAAV). Whereas AAV packages a single strand of DNA and must wait for its second strand to be synthesized, scAAV packages two shorter strands that are complementary to each other.
Self-complementary adeno-associated virus (scAAV) is a viral vector engineered from the naturally occurring adeno-associated virus (AAV) to be used as a tool for gene therapy. [1] Use of recombinant AAV (rAAV) has been successful in clinical trials addressing a variety of diseases. [ 2 ]
One disadvantage is that they are not able to carry large amounts of foreign genetic materials. Furthermore, the need to express the complementary strand for its single-stranded genome may delay transgene expression. [45] As of 2020, 11 different AAV serotypes—differing by capsid structure and consequently by tropism—had been identified. [43]
Recombinant adeno-associated virus (rAAV) based genome engineering is a genome editing platform centered on the use of recombinant AAV vectors that enables insertion, deletion or substitution of DNA sequences into the genomes of live mammalian cells.

The accident currently under investigation, but an incident during the final / go around, caused the plane to crash land onto 12L, skid the length of the runway, and finally came to rest pointing WSW between runway entry points Mike-13 and Mike-13A, close to the end of RWY 12L / THR 30R.
Accident date Location News org. Description F I Official cause 2022-11-22 Charlotte, North Carolina, United States : WBTV: The Robinson R44 helicopter went into rapid descent and crashed in a grassy area adjacent to a southbound intersectional lane of I-77, as the pilot was conducting a news-gathering training simulation accompanied by a WBTV staff meteorologist.
The crash was one of several accidents in the area due to heavy fog, police said. St John Sheriff Mike Tregre said that there was a total of 25 crashes on the road, involving three 18-wheel trucks ...
