Establishing polarized surfaces enables cells to carry out specialized tasks. In this issue, Lee et al. present a mechanism for cell polarization in which localized peroxidases are used to position the Casparian strip, a diffusion barrier deposited between endodermal cells in plant roots.

The nucleus is the largest organelle and is commonly depicted in the center of the cell. Yet during cell division, migration, and differentiation, it frequently moves to an asymmetric position aligned with cell function. We consider the toolbox of proteins that move and anchor the nucleus within the cell and how forces generated by the cytoskeleton are coupled to the nucleus to move it. The sig...

Spatial projection and temporal integration are two prominent theories of visual localization for moving stimuli which gain most of their explanatory power from a single process. Spatial projection theories posit that a moving stimulus' perceived position is projected forwards in order to compensate for processing delays (Eagleman & Sejnowski, 2007; Nijhawan, 2008). Temporal integration theorie...

Background: Hospitals as the essential health service providers should manage their performance during incidents and disasters. The Hospital Incident Command System (HICS) is helpful in this regard. The establishment of this system assists the hospital disaster risk management committee to get prepared in emergency situations. This study aimed to assess the effect of HICS establishment on prepa...

Abstract Background and Objectives Over-ordering of blood before operation can cause unnecessary cross matches, blood bank staff overload, blood unit wastages due to outdating, and increase hospital costs. So, we aimed to survey the efficacy of MSBOS on blood utilization in Faghihi Hospital, Shiraz, Iran.   Materials and Methods This cross sectional study was conducted over a three month per...

Multicellular animals have evolved conserved signaling pathways that translate cell polarity cues into mitotic spindle positioning to control the orientation of cell division within complex tissue structures. These oriented cell divisions are essential for the development of cell diversity and the maintenance of tissue homeostasis. Despite intense efforts, the molecular mechanisms that control ...
