Gait Analysis of Patients After Allogeneic Hematopoietic Cell Transplantation Reveals Impairments of Functional Performance.

After allogeneic hematopoietic cell transplantation (alloHCT), patients often report functional impairments like reduced gait speed and muscle weakness. These impairments can increase the risk of adverse health events similar to elderly populations. However, they have not been quantified in patients after alloHCT (PATs).

Designer amphiphilic proteins as building blocks for the intracellular formation of organelle-like compartments.

Nanoscale biological materials formed by the assembly of defined block-domain proteins control the formation of cellular compartments such as organelles. Here, we introduce an approach to intentionally 'program' the de novo synthesis and self-assembly of genetically encoded amphiphilic proteins to form cellular compartments, or organelles, in Escherichia coli. These proteins serve as building blocks for the formation of artificial compartments in vivo in a similar way to lipid-based organelles.

Coherent total internal reflection dark-field microscopy: label-free imaging beyond the diffraction limit.

Coherent imaging is barely applicable in life-science microscopy due to multiple interference artifacts. Here, we show how these interferences can be used to improve image resolution and contrast. We present a dark-field microscopy technique with evanescent illumination via total internal reflection that delivers high-contrast images of coherently scattering samples.

Patchwork organization of the yeast plasma membrane into numerous coexisting domains.

The plasma membrane is made up of lipids and proteins, and serves as an active interface between the cell and its environment. Many plasma-membrane proteins are laterally segregated in the plane of the membrane, but the underlying mechanisms remain controversial. Here we investigate the distribution and dynamics of a representative set of plasma-membrane-associated proteins in yeast cells.
