Outcomes of single versus sequential vein grafts in isolated coronary artery bypass surgery: Insights from a large tertiary care center.

Background: Saphenous venous grafts remain the most widely used conduits in coronary artery bypass graft surgery (CABG). Data comparing outcomes of single saphenous venous grafting (SinCABG) versus sequential venous grafting (SeqCABG), however, are limited.

Methods: Between 2002 and 2012, 2375 patients with 3-vessel coronary artery disease underwent isolated elective CABG at the Leipzig Heart Center with a left internal mammary artery graft to left anterior descending artery and ≥2 distal saphenous vein graft anastomoses.

Formation of Black Silicon in a Process of Plasma Etching with Passivation in a SF/O Gas Mixture.

This article discusses a method for forming black silicon using plasma etching at a sample temperature range from -20 °C to +20 °C in a mixture of oxygen and sulfur hexafluoride. The surface morphology of the resulting structures, the autocorrelation function of surface features, and reflectivity were studied depending on the process parameters-the composition of the plasma mixture, temperature and other discharge parameters (radical concentrations). The relationship between these parameters and the concentrations of oxygen and fluorine radicals in plasma is shown.

[The use of antioxidants in combination therapy of chronic prostatitis].

Currently, the significance of the chronic prostatitis (CP) is undoubted. Oxidative stress is considered as one of the standard mechanisms of cellular damage that is associated with inflammatory diseases such as CP. When choosing the combination therapy for this group of patients, a correction of oxidative stress is pathogenetically justified.

[Evaluation of the effectiveness of various regimens of the immunomodulatory drug Superlimf in the prevention of relapses of chronic abacterial prostatitis].

Introduction: Immune defense mechanisms, including a decrease in the functional activity of monocytes/macrophages, neutrophils, as well as a violation of the balance of pro- and anti-inflammatory cytokines, are important in the development of chronic abacterial prostatitis (CAP). The discovery of the cytokine system and the determination of their biological role in the development and functioning of the immune system and in the pathogenesis of a wide range of human diseases led to the development of a new direction in immunotherapy - cytokine therapy. The aim of the study was to evaluate the effectiveness of various regimens of the use of the immunomodulatory drug Superlimf in the prevention of recurrence of CAP.

Bioprinting Soft 3D Models of Hematopoiesis using Natural Silk Fibroin-Based Bioink Efficiently Supports Platelet Differentiation.

Hematopoietic stem and progenitor cells (HSPCs) continuously generate platelets throughout one's life. Inherited Platelet Disorders affect ≈ 3 million individuals worldwide and are characterized by defects in platelet formation or function. A critical challenge in the identification of these diseases lies in the absence of models that facilitate the study of hematopoiesis ex vivo.
