Extracellular Matrix of Echinoderms.

This review considers available data on the composition of the extracellular matrix (ECM) in echinoderms. The connective tissue in these animals has a rather complex organization. It includes a wide range of structural ECM proteins, as well as various proteases and their inhibitors.

Muscle Regeneration in Holothurians without the Upregulation of Muscle Genes.

The holothurian is capable of fully restoring its muscles after transverse dissection. Although the regeneration of these structures is well studied at the cellular level, the molecular basis of the process remains poorly understood. To identify genes that may be involved in the regulation of muscle regeneration, the transcriptome of the longitudinal muscle band of has been sequenced at different time periods post-injury.

Matrix Metalloproteinases and Tissue Inhibitors of Metalloproteinases in Echinoderms: Structure and Possible Functions.

Echinoderms are one of the most ancient groups of invertebrates. The study of their genomes has made it possible to conclude that these animals have a wide variety of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs). The phylogenetic analysis shows that the MMPs and TIMPs underwent repeated duplication and active divergence after the separation of Ambulacraria (Echinodermata+Hemichordata) from the Chordata.

[Surgical prophylaxis of pulmonary embolism].

144 patients were operated on for deep vein thrombosis. Color duplex lower limb vessels scanning was he basic diagnostic procedure performed preoperatively. Operative treatment corresponded floating trombectomy and main vein placation as a means of pulmonary embolism prophylaxis.

[Prospects for surgical and combined methods for treating acute coronary syndrome].

From 1997 to 2000 diagnostic coronaroangiography was performed in 334 patients with acute coronary syndrome (ACS) which is the group of diseases with common pathophysiological mechanism, namely coronary artery thrombosis. ACS needs revascularization of the affected artery as quickly as possible. 26.
