Complications following type 3 excision by needle excision of the transformation zone: a case series report
Objective:
To determine short-term complications and related risk factors following needle excision of the transformation zone (NETZ).
Materials And Methods:
A case series of 105 women with NETZ for cervical pathology between 2006-2013 in a single center.
Results:
The overall complication rate was 22.9%. Heavy primary bleeding occurred in 12.4% of cases (<500 ml), secondary hemorrhage 7.6%, emergency hysterectomy 1.9%, and cervical stenosis 2.9%. Where excision depth was > 20 mm, this was a non-significant increase in the risk of hemorrhage, but a significant reduction in the risk of a subsequent hysterectomy (p = 0.035).
Conclusion:
NETZ is associated with a number of complications and recognition of risk factors should be considered when planning type 3 excisional procedures and counseling women.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Types Of Transformers
If the ratio of the number of turns in the secondary winding to that of the primary winding is greater than one, then the transformer is said to be a step-up transformer. In a step-up transformer, the voltage at the secondary winding is greater than the voltage applied at the primary winding.
However, if this ratio is less than one, the transformer is said to be a step-down...
