Slippery liquid-infused porous surfaces (SLIPS) have emerged as a unique approach to creating that can resist fouling when placed in contact with aqueous media, organic fluids, or biological organisms. These are composed of essentially two components: liquid lubricant is locked within the protrusions textured solid due capillarity. Drops, immiscible lubricant, exhibit high mobility and very-low...

Cell motility driven by actin polymerization is pivotal to the development and survival of organisms and individual cells. Motile cells plated on flat substrates form membrane protrusions called lamellipodia. The protrusions repeatedly appear and retract in all directions. If a lamellipodium is stabilized and lasts for some time, it can take over the lead and determine the direction of cell mot...

BACKGROUND AND PURPOSE An infrequent occurrence during endovascular treatment is protusion of detachable coils into the parent lumen with a subsequent thrombosis within in the parent vessel or embolic events. We report the short- and intermediate-term angiographic and clinical outcomes of patients who experience coil or loop protrusions and are managed with medical or additional endovascular tr...

Colony-stimulating factor 1 (CSF-1) is an important physiological chemoattractant for macrophages. The mechanisms by which CSF-1 elicits the formation of filamentous actin (F-actin)-rich membrane protrusions and induces macrophage migration are not fully understood. In particular, very little is known regarding the contribution of the different members of the Wiskott-Aldrich Syndrome protein (W...

Long cell protrusions, which are effectively one-dimensional, highly dynamic subcellular structures. Length of many such protrusions keep fluctuating about the mean value even in steady state. We develop here a stochastic model motivated by length fluctuations type appendage an eukaryotic called flagellum (also cilium). Exploiting techniques developed for calculation level-crossing statistics r...

A living cell uses long tubular appendages for locomotion and sensory purposes. Hence, assembling maintaining a protrusion of correct length is crucial its survival overall performance. Usually the protrusions lack machinery synthesis building blocks imports them from body. What are unique features transport logistics which facilitate exchange these between protrusion? kind `rulers' `timers' do...
