Prostate cancer infiltrating the bladder sphincter successfully treated with Electrochemotherapy: a case report.

We demonstrate feasibility and safety of Electrochemotherapy for treatment of a prostate cancer (PCa) with infiltration of the urethral sphincter. The patient remained continent and potent, toxicity was low, and 6 months of follow-up showed no cancer activity. We conclude that Electrochemotherapy should be further evaluated as treatment strategy for locally advanced PCa.

Treatment of lymph node metastases from gastric cancer with a combination of Irreversible Electroporation and Electrochemotherapy: a case report.

The combination of Irreversible Electroporation and Electrochemotherapy (IRECT) was well tolerated, safe, and had antitumor activity in this case study of a patient with lymph node metastases from gastric cancer. We therefore recommend the consideration of further clinical studies to investigate the treatment of cancerous tissue with IRECT.

Catheter venography for the assessment of internal jugular veins and azygous vein: position statement by expert panel of the International Society for Neurovascular Disease.

This document by an expert panel of the International Society for Neurovascular Disease is aimed at presenting current technique and interpretation of catheter venography of the internal jugular veins, azygous vein and other veins draining the central nervous system. Although interventionalists agree on general rules, significant differences exist in terms of details of venographic technique and interpretations of angiographic pictures. It is also suggested that debatable findings should be investigated using multimodal diagnostics. Finally, the authors recommend that any publication on chronic cerebrospinal venous insufficiency should include detailed description of venographic technique used, to facilitate a comparison of published results in this area.

Dynamics of skeleton formation in the Lake Baikal sponge Lubomirskia baicalensis. Part I. Biological and biochemical studies.

In ancient Lake Baikal (East Siberia), freshwater sponges have diversified to an extraordinary degree. The skeleton of Lubomirskia baicalensis, which attains a size of up to 1 m, is constructed from spicules, which are cemented into longitudinal bundles. Our X-ray analysis revealed that the architecture of the specimens follows a highly ordered radiate accretive growth pattern. The spicules have a central axial canal with an axial filament inside. This organic filament is composed of silicatein, the major enzyme involved in silica formation of the spicules. We found that the specific activity of silicatein in samples from the non-growing (basal) zone is much lower than in those from the growth zone (tips) and that even the composition of this molecule differs in these regions. The present study shows for the first time that the turnover of silicatein, the major element of the axial canal of sponge spicules, changes within a sponge specimen depending on the region in which it is found.
