Citrullination Accompanies the Development of Carotid Atherosclerotic Plaques.

Background: Citrullination represents a post-translational modification primarily mediated by peptidylarginine deiminase (PADI) 2 and 4 and resulting in the conversion of positively charged peptidylarginine to neutrally charged peptidylcitrulline. Molecular consequences of citrullination include the generation of neoepitopes which provoke the production of autoantibodies implicated in the development of autoimmune diseases. As citrullination initiates, promotes, and is enhanced by aseptic inflammation which plays a pivotal role in atherosclerosis, we proposed that citrullination might accompany the development of atherosclerotic vascular disease.

Electrospun bioresorbable polymer membranes for coronary artery stents.

Percutaneous coronary intervention, a common treatment for atherosclerotic coronary artery lesions, occasionally results in perforations associated with increased mortality rates. Stents coated with a bioresorbable polymer membrane may offer an effective solution for sealing coronary artery perforations. Additionally, such coatings could be effective in mitigating neointimal hyperplasia within the vascular lumen and correcting symptomatic aneurysms.

Salt concentration in substrate modulates the composition of bacterial and yeast microbiomes of .

Microbiomes influence the physiology and behavior of multicellular organisms and contribute to their adaptation to changing environmental conditions. However, yeast and bacterial microbiota have usually been studied separately; therefore, the interaction between bacterial and yeast communities in the gut of () is often overlooked. In this study, we investigate the correlation between bacterial and yeast communities in the gut of .

Changes in Composition of Some Bioactive Molecules upon Inclusion of Probiotic Strains into a Standard Yogurt Starter Culture.

Incorporation of probiotic into a standard yogurt starter culture can drastically improve its health promoting properties. However, besides being an advantage in itself, the incorporation of a new probiotic strain can significantly affect the overall composition of fermented milk. In this article, the effect of incorporation of the probiotic strains (KF1 and MA3) into several standard yogurt starter cultures (consisting of the following strains: 16t and either Lb100 or Lb200) was investigated.

Comparison of the Patency and Regenerative Potential of Biodegradable Vascular Prostheses of Different Polymer Compositions in an Ovine Model.

The lack of suitable autologous grafts and the impossibility of using synthetic prostheses for small artery reconstruction make it necessary to develop alternative efficient vascular grafts. In this study, we fabricated an electrospun biodegradable poly(ε-caprolactone) (PCL) prosthesis and poly(3-hydroxybutyrate-co-3-hydroxyvalerate)/poly(ε-caprolactone) (PHBV/PCL) prosthesis loaded with iloprost (a prostacyclin analog) as an antithrombotic drug and cationic amphiphile with antibacterial activity. The prostheses were characterized in terms of their drug release, mechanical properties, and hemocompatibility.
