Percutaneous reconstruction of chronic total occlusion of brachiocephalic vein using transseptal needle in dialysis-dependent patient.

Placement of a dialysis catheter substantially increases the risk of central vein stenosis. 52-year-old female with end-stage renal disease and a right brachial-cephalic hemodialysis access presented with right arm swelling. The chronic total occlusion of right brachiocephalic vein was refractory to wire traversal.

In vivo extraction of Arabidopsis cell turgor pressure using nanoindentation in conjunction with finite element modeling.

Turgor pressure in plant cells is involved in many important processes. Stable and normal turgor pressure is required for healthy growth of a plant, and changes in turgor pressure are indicative of changes taking place within the plant tissue. The ability to quantify the turgor pressure of plant cells in vivo would provide opportunities to understand better the process of pressure regulation within plants, especially when plant stress is considered, and to understand the role of turgor pressure in cellular signaling.

Proboscis lateralis: case report and overview.

We present a rare case of the congenital malformation of the nose in a 10-month-old baby.

Viscoelastic properties of cell walls of single living plant cells determined by dynamic nanoindentation.

Plant development results from controlled cell divisions, structural modifications, and reorganizations of the cell wall. Thereby, regulation of cell wall behaviour takes place at multiple length scales involving compositional and architectural aspects in addition to various developmental and/or environmental factors. The physical properties of the primary wall are largely determined by the nature of the complex polymer network, which exhibits time-dependent behaviour representative of viscoelastic materials.
