Caveolins form plasmalemnal invaginated caveolae. They also locate around intracellular lipid droplets but their role in this location remains unclear. By studying primary adipocytes that highly express caveolin-1, we characterized the impact of caveolin-1 deficiency on lipid droplet proteome and lipidome. We identified several missing proteins on the lipid droplet surface of caveolin-deficient...

A droplet placed in a liquid-liquid solution is expected to grow, or shrink, in time as approximately t;{1/2}. In this Letter, we report experimental evidence that when the composition in the interface is far from thermodynamic equilibrium due to the nonideality of the mixture, a droplet shrinks as approximately t. This scaling is due to the coupling between mass and momentum transfer known as ...

Low viscosity (<100 cSt) silicon oil droplets are placed on a high viscosity (1000 cSt) oil bath that vibrates vertically. The viscosity difference ensures that the droplet is more deformed than the bath interface. Droplets bounce periodically on the bath when the acceleration of its sinusoidal motion is larger than a threshold value. The threshold is minimum for a particular frequency of excit...

This paper describes and characterizes the electrowetting-induced movement of droplets in an immiscible medium. When an aqueous droplet undergoes electrowetting-induced motion in a continuous phase of olive oil, the droplet glides through the olive oil at a much higher velocity than is possible in the absence of oil and is able to travel greater than 10 times the electrode separation distance. ...

Background: Fear of falling is common amongst older adults, especially those who live in nursing homes. This study aimed to determinate factors associated with fear of falling and functional independence in older adults living in nursing homes. Methods: This was a cross-sectional study using a convenience sampling method to enroll 200 older adults living in nursing homes from 25 senior cente...

A computer numerical control (CNC) apparatus was used to perform droplet centrifugation, droplet DNA extraction, and rapid droplet thermocycling on a single superhydrophobic surface and a multi-chambered PCB heater. Droplets were manipulated using "wire-guided" method (a pipette tip was used in this study). This methodology can be easily adapted to existing commercial robotic pipetting system, ...

Computational fluid dynamics is used to model atmospheric transport and droplet-thin film (surface) collisions in desorption electrospray ionization; experimentally obtained droplet properties are replicated in the simulations while a "droplet pick-up" mechanism of analyte transport is confirmed.

We consider the problem of an ideal polymer confined in a droplet. When the droplet radius is smaller than the (unconfined) polymer radius of gyration, the polymer entropy will depend on the droplet shape. We compute the resulting surface free

background: in this study we investigated the differences of functional gait and balance measures between patients with chronic stroke with different level of concern about falling. methods: fifty-four patients with chronic stroke participated in this observational, cross-sectional study. the level of concern relating to falls was assessed by using the falls efficacy scale-international. thirty...
