A panel discussion on elder abuse and the law, participated by Gerald J. Jogerst, M. Jane Brady, Carmel B. Dyer, and moderated by Ileana Arias, is presented. Arias discusses that although elder ...mistreatment is a problem that is generally ignored by researchers and practitioners, approximately 450,000 individuals who are sixty years old and older are mistreated every year in the US.
Our lab has used an optical coherence microscope (OCM) to assess both the structure of tissue-engineered corneal constructs and their transparency. Currently, we are not able to resolve cells versus ...collagen matrix material in the images produced. We would like to distinguish cells in order to determine if they are viable while growing in culture and also if they are significantly contributing to the light scattering in the tissue. In order to do this, we are currently investigating the use of immunogold labeling. Gold nanoparticles are high scatterers and can create contrast in images. We have conjugated gold nanoparticles to antibodies specific to the alpha/sub 5/beta/sub 1/ integrins expressed in some corneal cells. This choice of target should allow assessment of the phenotypic behavior of the cells in the tissue, as different integrins are expressed in different phenotypes. This study applies the immunogold technique to study cultured corneal cells using the OCM with the ultimate goal of monitoring cellular behavior in engineered tissue and corroborating results from standard histological methods.
We analyzed the Marangoni convection induced in the liquid crystalline material of 8CB in sandwich cells under temperature gradient. By using fluorescence photo-bleaching method, we measured the flow ...field near air interface. In the coexistence state of the smectic and the nematic phases, the direction of the observed flow was opposite from that expected from the temperature dependence of surface tension. Moreover, in the coexistence state of the nematic and isotropic phases, the flow field depended on the coating materials of the cell substrates. As for the formation of the flow field, these flow properties indicate the existence of another important physical factor in addition to the surface tension gradient.
It has been reported that if a shear flow is applied to the nematic phase of 8CB, some dynamical structure are induced. To clarify these structures is more detail, transient dielectric response after ...the application of the shear flow was measured. In the flow alignment region the dielectric permittivity decreased monotonously, while in the precession region a damped-oscillation of the dielectric permittivity was measured with critical increases in the oscillating frequency and damping faster when approaching to the nematic to smectic A phase transition point. These results will be discussed based on the fluctuation of smectic A structure.
When a steady shear flow is applied to the nematic phase of 5CB, nonlinear dielectric properties are observed. In the dielectric spectra, dielectric dispersions are recognized in the nonlinear ...dielectric constants but not in the linear one. These shear-induced nonlinear dielectric properties under the shear flow will be discussed based on the orientational change of the director under the shear and the electric fields.

Daniel Lesser, senior managing director at CB Richard Ellis, addressing nearly 400 hoteliers during JMBM's annual Meet the Money hotel financing conference in May, was optimistic about the continued, ...albeit slower, growth within the lodging industry. He told hoteliers that 2008 is a great time to grow their portfolios. One Meet the Money panel, "Who's funding now?" featured six representatives from financial organizations who said their companies are actively lending and discussed what type of projects they are targeting. As far as new-build projects, lenders were nearly as optimistic, echoing the statement that more equity will be needed to find construction loans.
