Magnetization and Anisotropy of Magnetic Susceptibility of a Liquid Crystal Doped with Chlorophylls a, b and Carotenoids.

The magnetization and anisotropy of magnetic susceptibility of a 5CB nematic liquid crystal doped three extracts containing chlorophylls a and b and carotenoids in different weight percentage has been studied. The extracts have been dissolved in the liquid crystal matrix at a concentration of 2%. The magnetic susceptibility of the substances has been measured by the Faraday-Curie balance method.

[Surgery for complicated accessory lobe of the azygos vein].

Congenital anomalies of respiratory system are quite diverse and not all of them are subject to surgical treatment. One example is accessory lobe of the azygos vein. This anomaly usually has no clinical manifestations and requires only follow-up, as well as attention in surgery on the right half of the chest for some other disease.

[Surgery for mediastinal teratoma containing pancreatic tissue].

Surgery for mediastinal tumors is still one of the most difficult in modern medicine. This is due to vital organs and various nature of tumors in this area. Teratomas are relatively rare among mediastinal tumors.

[Improving surgical technique for tracheal resection with anastomosis].

Objective: To present modern aspects of improving surgical techniques in tracheal resection developed in recent years.

Material And Methods: The authors have the most extensive experience in tracheal surgery (>2.000 patients over the past 50 years).

[Giant traumatic diaphragmatic hernia as a complication after laparoscopic liver surgery].

Laparoscopic surgery is now one of the main options for patients with surgical diseases of abdominal cavity, pelvis and retroperitoneal space. Postoperative complications are known, and methods for their prevention after such interventions are well developed. However, there are rare complications, and their management deserves a special attention.
