Maxillofacial gunshot wounds in peacetime
Abstract:
The treatment of maxillofacial gunshot wounds in peacetime is an urgent and difficult problem. The emergence of new types of civilian weapons and relatively small current clinical experience does not allow generating recommendations for the treatment of this pathology. It presents a statistical analysis of injuries in St. Petersburg 2004-2014 restricted firearms destruction and experimental study of the harmful effect of these weapons on the fabric maxillofacial experimental animals (pigs). The features of the clinical picture, diagnosis and surgical treatment of wounds of the maxillofacial region, caused by a firearm -restricted lesions and wounds with extensive tissue damage maxillofacial caused a hunting weapon are considered.

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...

DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...
