“This CP-868596 concentration study presents packaged microscale liquid lenses actuated with liquid droplets of 300-700 mu m in diameter using the dielectric force manipulation. The liquid microlens demonstrated function focal length tunability in a plastic package. The focal length of the liquid lens with a lens droplet of 500 mu m in diameter is shortened from 4.4 to 2.2 mm when voltages applied change from 0 to 79 V-rms. Dynamic responses that are analyzed using 2000 frames/s high speed motion cameras show that the advancing and receding times

are measured to be 90 and 60 ms, respectively. The size effect of dielectric liquid microlens is characterized for a lens droplet of 300-700 mu m in diameter in an aspect of focal length. (C) 2010 American Institute of Physics. [doi:10.1063/1.3494030]“
“Here, we present a simple chemical modification of poly(dimethylsiloxane) (PDMS) by curing a mixture DAPT of 2 wt% undecylenic acid (UDA) in PDMS prepolymer on a gold-coated glass slide. This gold slide had been previously pretreated with a self-assembled hydrophilic monolayer of 3-mercaptopropionic acid (MPA). During curing of the UDA/PDMS prepolymer, the hydrophilic UDA carboxyl moieties diffuses toward the hydrophilic MPA carboxyl moieties on the gold surface. This diffusion of the UDA within the PDMS prepolymer to the surface

is a direct result of surface energy minimization. Once completely cured, the PDMS is peeled off the gold substrate, thereby exposing the interfacial carboxyl groups. These groups are then available for subsequent attachment of 5′-amino terminated DNA oligonucleotides via amide linkages. Our results show that the covalently tethered oligonucleotides can successfully capture fluorescein-labeled complementary oligonucleotides via

hybridization, which are visualized using fluorescence microscopy. (C) 2010 American Institute of Physics. [doi:10.1063/1.3523055]“
“Purpose of review

This article summarizes the current state of the epidemiology, diagnosis, and management of human herpesvirus 6 (HHV-6) infection after solid organ transplantation.

Recent findings

HHV-6 reactivates commonly during the early weeks after solid organ transplantation. However, disease due to HHV-6 is uncommon and is manifested as a febrile illness selleck chemicals associated with rash and tissue-invasive manifestations such as encephalitis, hepatitis, pneumonitis, and gastrointestinal disease. HHV-6 has also been indirectly associated with other opportunistic infections such as cytomegalovirus and fungal infections. Molecular tests such as PCR assays are preferred methods for the diagnosis of HHV-6 infection. Recent guideline from the American Society of Transplantation Infectious Disease Community of Practice does not recommend specific antiviral prophylaxis or preemptive therapy for HHV-6 infection.
