Combined surgical treatment of giant cavernous hepatic hemangioma: A case report.

Introduction And Importance: Hepatic hemangiomas are the most common benign liver tumors, which in most cases are small in size and do not require specific treatment. Giant hepatic hemangiomas are a rare pathology. The purpose of this report is to demonstrate the case of combined treatment of giant hepatic hemangioma.

Double-tract reconstruction for oesofagocardial gastric cancer: A systematic review.

The number of people with gastric cardia and distal oesophageal cancers has increased in the last five years. The surgical treatment method of choice is proximal gastrectomy, with an option being reconstruction of the gastrointestinal tract. There are many reconstruction techniques for anastomosis of the oesophagus and distal parts of the digestive tract.

[Treatment tactics of hemorroidal disease stage III-IV].

The Miligan-Morgan's operation has long been considered to be the "golden standard" of hemorrhoids' stage I-III treatment. The invention of distal branches of the upper rectal artery' suture ligation with mucopexia and lifting of the anal canal mucosa discovered new possibilities for hemorrhoids surgery, though there are still some questions considering long-term results. 151 cases of recurrence within 1-6 months were analyzed.

Crystalline titania nanoparticles synthesized in nonpolar Lα lecithin liquid-crystalline media in one stage at ambient conditions.

High-temperature modification of titania in the form of nanoplatelets is synthesized fast in one step at ambient conditions without any additional treatment like aging or calcination. Lecithin, which is the main component of lipid matrix of biological membranes, is first used as a structure-driven template. It is demonstrated that this natural surfactant can self-organize into lamellar L(α) mesophase when small amounts of water are admixed in its solution in nonpolar solvent.

Gelling of otherwise nongelable polysaccharides.

It was shown first that solutions of nongelable polysaccharides, including such practically important ones as chitosan, hyaluronate, and cyclodextrin, can be gelled by generating silica in situ via sol-gel processing. This could be done owing to a novel silica precursor that is completely water-soluble and compatible with biopolymers. The gelation was caused by mineralization of carbohydrate macromolecules, which strengthened them and provided their cross-linking.
