TL;DR: The optimum distance for avoiding person-to-person virus transmission is investigated and the use of face masks and eye protection to prevent transmission of viruses is assessed to investigate the effects of physical distance, face masks, and eye Protection on virus transmission in health-care and non-health-care settings.

TL;DR: In this article, the authors examined whether the timing of the initiation of maintenance dialysis influenced survival among patients with chronic kidney disease and found no significant difference between the groups in the frequency of adverse events, infections, or complications of dialysis.

TL;DR: In this paper, a 2D discrete model for granular materials with rolling resistance is presented, which consists of a geometrically derived kinematical model, physically based mechanical contact models and locally equilibrated equations governing the motion of the rigid particles; only one additional parameter δ needs to be introduced in the model when compared with the standard discrete element method.

TL;DR: It is demonstrated that macrophages not only act as effectors of immune injury but can be induced to provide protection against immune injury.

TL;DR: In this article, the E-Cadherin/β-catenin complex plays an important role in maintaining epithelial integrity and disrupting this complex affect not only the adhesive repertoire of a cell, but also the Wnt-signaling pathway.
