This work reports on a simple system for quantitative sensing of a target analyte based on agglutination in microchannels. Functionalized microbeads and analyte with no prior incubation are flowed in droplets (~2μL) through a thin silicone tube filled with mineral oil at a flow rate of 150 μL/min. Hydrodynamic forces alone produce a highly efficient mixing of the beads within the droplet, witho...

We developed a photoacoustic imaging system that has real-time imaging capability with optical resolution. The imaging system is capable of scanning at 20 Hz over a 9 mm range and up to 40 Hz over a 1 mm scanning range. A focused laser beam provides a lateral resolution of 3.4 μm as measured in an optically nonscattering medium. Flows of micrometer-sized carbon particles or whole blood in a sil...

background peripheral nerve repair is often complicated by fibroblastic scar formation, nerve dysfunction, and traumatic neuroma formation. use of silicone may improve outcomes of these repairs. in this study, we tried to evaluate effectiveness of silicone gel on rats’ sciatic nerve repair, axon regeneration and scar formation around and in the nervous tissues. methods this experimental study w...

Personal cooling garments were reported effective in improving thermal comfort hot environments. In this study, three liquid–air hybrid and one control garment designed made: aluminum-tube fan (AAL), silicone-tube (SAL), with inner yarn fabric (YAL), a (CON) without the sources. Subject trials performed by eight female subjects climate chamber to simulate summer indoor working environment at 32...

conclusions within the limitations of this study, disinfectants were able to completely eliminate microorganisms carried by the alginate impressions. however, more efficient disinfection methods are needed to eliminate the risk of cross contamination by condensational silicone impressions. background dental impressions often carry microorganisms that may cause cross-infection from patients to d...

AIM To assess the effect of estradiol-17beta (E(2)) and bisphenol A (BPA) administered chronically by implanting a silicone tube throughout pregnancy and lactation on male pups' reproductive system in ICR mice. METHODS Female mice were implanted with a tube filled with 10 ng, 500 ng, 1 microg, or 10 microg of E(2), or 100 microg or 5 mg of BPA, before mating. The tube was kept in the mice thr...

AIM To evaluate the feasibility of repairing a common bile duct defect with a decellularized ureteral graft in a porcine model. METHODS Eighteen pigs were randomly divided into three groups. An approximately 1 cm segment of the common bile duct was excised from all the pigs. The defect was repaired using a 2 cm long decellularized ureteral graft over a T-tube (T-tube group, n = 6) or a silico...
