The majority of protein disulfides in cells is considered an important inert structural, rather than a dynamic regulatory, determinant of protein function. Here, we show that some disulfides in proteins also are regulated by cell redox status with functional consequences. We find that reactive oxygen species (ROS) produced by mitochondria are actively used by cells to facilitate cell-surface pr...

we study the equilibrium states for an energy functional with a parametric force field on a region of a surface. consideration of free equilibrium states is based on lyusternik - schnirelman's and skrypnik's variational methods. consideration of equilibrium states under a constraint of geometrical character is based on an analog of skrypnik's method, described in cite{vyr3}. in local coordinate...

coronary artery disease is the leading cause of death worldwide. in this study, we compared two surgical methods of left internal mammary artery (lima) anastomosis on left anterior descending (lad) artery in patients with severe diffuse lesions. a total of 40 patients were included in our study and randomly assigned into two groups. in group a, after a long arteriotomy on lad, the posterior sur...

While the concept of crowdsourcing has generated significant interest in the information systems (IS) research community, the application of crowdsourcing for research itself remains limited. This limitation in the adoption of crowdsourcing by researchers is partly explained by the lack of a crowdsourcing platform that is suitable for their needs. This paper presents the findings of a focus gro...

The effects of changes in cellular characteristics and dissolved organic matter (DOM) on dissolved air flotation (DAF) harvesting of Chlorella zofingiensis at the different growth phases were studied. Harvesting efficiency increased with Al(3+) dosage and reached more than 90%, regardless of growth phases. In the absence of DOM, the ratio of Al(3+) dosage to surface functional group concentrati...
