Thoracic aortic aneurysm (TAA) is a life-threatening condition associated with high mortality, in which the aortic wall is deformed due to congenital or age-associated pathological changes. The mechanisms of TAA development remain to be studied in detail, and are the subject of active research. In this review, we describe the morphological changes of the aortic wall in TAA.

Material And Methods: The investigation material was aortic aneurysm wall segments obtained during surgery. Among the patients, there were 20 men and 5 women.
The paper describes a clinical case of gigantic aneurysm of one of the coronary arteries. It considers the morphological and immunohistochemical characteristics of the wall of the blood vessel with the detected signs of coronaritis. The authors have determined that Kawasaki disease could be retrospectively diagnosed in early childhood.

Corrosion inhibition by microbial processes may be due to the formation of mineral deposition layers on metal objects. Such deposition layers have been found in archaeological studies on ancient metal objects, buried in soil, which were hardly corroded.

Based on the results of the comparative analysis concerning relatedness and evolutional difference of the 16S-23S nucleotide sequences of the middle ribosomal cluster and 23S rRNA I domain, and based on identification of phylogenetic position for Chlamydophila pneumoniae and Chlamydia trichomatis strains released from monkeys, relatedness of the above stated isolates with similar strains released from humans and with strains having nucleotide sequences presented in the GenBank electronic database has been detected for the first time ever. Position of these isolates in the Chlamydiaceae family phylogenetic tree has been identified. The evolutional position of the investigated original Chlamydia and Chlamydophila strains close to analogous strains from the Gen-Bank electronic database has been demonstrated.
