Microscopic hair-like structures, such as cilia, exist ubiquitously in nature and are used by various organisms for transportation purposes. Many efforts have been made to mimic the fluid pumping function of cilia, but most of the fabrication processes of these ‘‘artificial cilia’’ are tedious and expensive, hindering their practical applications. In this paper, an attractive and potentially co...

We present the design, fabrication and testing of a novel all-optical 2D flow velocity sensor, inspired by a fish lateral line neuromast. This artificial neuromast consists of optical fibres inscribed with Bragg gratings supporting a fluid force recipient sphere. Its dynamic response is modelled based on the Stokes solution for unsteady flow around a sphere and found to agree with experimental ...

background: the relationship between metabolism and reproduction has been always considered as an important topic in female endocrinology. it seems that leptin is one of the involved factors in infertility. leptin, in addition to regulating body weight plays an important role in regulation of endocrine, reproductive and immune systems. the aim of this stduy is to compare serum and follicular fl...

In this chapter we study the effect of metachronal waves on the flow created by magnetically-driven artificial cilia in microchannels. We use a coupled magnetomechanical solid-fluid model that captures the physical interactions between the fluid flow, ciliary deformation and applied magnetic field. When a rotating magnetic field is applied to super-paramagnetic artificial cilia, they mimic the ...

Pioneering investigations conducted over a half century ago on tonicity, transcapillary fluid exchange, and the distribution of water and solute serve as a foundation for understanding the physiology of body fluid spaces. With passage of time, however, some of these concepts have lost their connectivity to more contemporary information. Here we examine the physical forces determining the compar...

Recently, a number of reports have been published on silicosis in workers exposed to artificial quartz conglomerates containing high levels of crystalline silica particles (70-90%) used in the construction of kitchen and bathroom surfaces. Three cases of silicosis in workers exposed to artificial quartz conglomerates are reported. The diagnosis was derived from both the International Labour Off...

We describe a method of fabrication of nanoporous flexible probes which work as artificial proboscises. The challenge of making probes with fast absorption rates and good retention capacity was addressed theoretically and experimentally. This work shows that the probe should possess two levels of pore hierarchy: nanopores are needed to enhance the capillary action and micrometer pores are requi...

M A N N E D SPACE flight is now a reality and data is available regarding the physiologic effects of short periods of weightlessness. 1 The results of our initial manned orbital space flights indicate that although certain phys io log ica l changes do occur during relatively short exposures to weightlessness, such changes have not been of operational significance and have been of a rather minor...

A heterogeneous and slowly progressive disease with extracellular amyloid-β (Aβ) deposits and intracellular hyperphosphorylated tau protein aggregates, Alzheimer's disease (AD) is already a hard nut to crack, featured with cognitive decline and memory lapse. Body fluid biomarkers are proved to be useful in exploring further study of AD, might benefit for a full comprehension of the etiopathogen...
