    Microelectrode and 133Cs nuclear magnetic resonance evidence for variable cytosolic and cytoplasmic nitrate pools in maize root tips (2005)

    Notizen: The effect of nitrate uptake on the subcellular distribution of tissue nitrate in 2–5 mm maize root tips was investigated by two complementary methods. First a novel in vivo analysis using 133Cs nuclear magnetic resonance (NMR) was used to demonstrate changes in the cytoplasmic and vacuolar pools during caesium nitrate uptake. This method depended on interpreting the nitrate-induced changes in the positions of the cytoplasmic and vacuolar caesium signals. The assignment of the signals was confirmed by using in vivo39K NMR to observe the displacement of cytoplasmic potassium into the vacuole during caesium uptake, and in vivo133Cs NMR to observe the displacement of cytoplasmic caesium into the vacuole during potassium uptake. Secondly nitrate-selective microelectrodes were used to quantify the change in the cytosolic nitrate activity that occurred in the outermost cells of root tips under the same conditions. Both methods showed that the detected nitrate pool increased over a period of 8–10 h in the presence of 10 m m nitrate and it is concluded that the data provide support for the view that homeostasis in the cytosolic and cytoplasmic nitrate pools is not necessarily an invariant characteristic of root tips.

    From robotic hands to human hands: a visualization and simulation engine for grasping research (2005)

    Notizen: Purpose - Robotic hands are still a long way from matching the grasping and manipulation capability of their human counterparts, but computer simulation may help us understand this disparity. We present our publicly available simulator, and describe our research projects involving the system including the development of a human hand model derived from experimental measurements. Design/methodology/approach - Unlike other simulation systems, our system was built specifically to analyze grasps. It can import a wide variety of robot designs by using standard descriptions of the kinematics and link geometries. Various components support the analysis of grasps, visualization of results, dynamic simulation of grasping tasks, and grasp planning. Findings - The simulator has been used in several grasping research problems and can be used to plan grasps for an actual robot. With the aid of a vision system, we have shown that these grasps can be executed by a robot. Research limitations/implications - We are currently developing methods to handle deformable surfaces, tendon driven models, and non-ideal joints in order to better model human grasping. Practical implications - This work is part of our current project to create a biomechanically realistic human hand model to better understand what features are most important to mimic in the designs of robotic hands. Such a model will also help clinicians better plan reconstructive hand surgeries. Originality/value - We describe our publicly available grasping simulator and review experiments performed with it. The paper demonstrates the usefulness of this system as a tool for grasping research.

    Multi-unit fixed partial denture for a bilateral cleft palate patient: a clinical report (2005)
    Oxford, UK : Blackwell Science Ltd
    Journal of oral rehabilitation 32 (2005), S. 0

    Notizen: summary  Patients with cleft palates eventually require definitive fixed or removable dental prostheses after the maintenance of arch alignment and occlusal relationship during adolescence. This case report presents application of a resin composite veneered fixed partial denture utilized as a definitive prosthesis for a bilateral cleft palate patient after stable occlusion had been established orthodontically. The composite veneered long span fixed partial denture provides adequate aesthetics and function.

    Notizen: [Auszug] Jaagsiekte sheep retrovirus (JSRV) causes a contagious lung cancer in sheep and goats, with significant animal health and economic consequences. The host range of JSRV is in part limited by species-specific differences in the virus entry receptor, hyaluronidase 2 (Hyal2), which is not ...
