Experimental surgery as part of the development of degradable biomaterials for cardiovascular surgery.

Introduction: Cardiovascular diseases are responsible for significant morbidity and mortality in the population. Artificial vascular grafts are often essential for surgical procedures in radical or palliative treatment. Many new biodegradable materials are currently under development.

Sternotomy in thyroid surgery.

Introduction: A bulky retrosternal goiter means for the surgeon to consider an extracervical approach, usually from a partial sternotomy. Methods: Retrospective evaluation of a group of thyroid operations requiring sternotomy in a ten-year period (year 2012–2021), in an attempt to predict the need for sternotomy. Results: We performed a total of 1254 thyroid operations, with partial sternotomy required in 11 cases (0.

Management of Concomitant Abdominal Aortic Aneurysm and Intra-abdominal, Retroperitoneal Malignancy.

Background/aim: As the population ages, there are increasing findings of coincidental diseases such as abdominal aortic aneurysm (AAA) and intra-abdominal, retroperitoneal malignancy. The aim of this study was to propose an optimal treatment procedure for these patients.

Patients And Methods: Over a twenty-year-period, surgery was performed on a total of 1,098 patients with AAA and 32 (2.

Transport of 4-deoxy- and 6-deoxy-D-glucose in baker's yeast.

Tritium-labelled 4-deoxy-D-glucose (4-dglc) and 6-deoxy-D-glucose (6-dgcl) were prepared by catalytic hydrogenolysis of the corresponding deoxyiodo derivatives with gaseous tritium. The two sugars are transported into Saccharomyces cerevisiae by both the constitutive glucose and the inducible galactose carrier. Uranyl ions are powerful inhibitors.
