Beyond Patienthood: Integrative medicine, healing environments and the journey toward new selfhood.

The purpose of this study is to learn about the relationship between participation in an integrative medicine program and the impact upon the social identities of seven individuals with cancer. Data were collected via semi-structured, face-to-face interviews and observations in the clinic space, and analyzed using a constant comparison method. All of the participants reported a change in their social identities as they transitioned between illness and wellness. The sub-themes that emerged included: the use of complementary and alternative medicine (CAM) as a means of fighting cancer after chemotherapy ended, maintaining health becoming a main occupation, and the “cancer filter” through which all other experiences are viewed, shaping the post-treatment phase of life. Overall, findings suggest that seeking CAM played a role in the participants’ transitions from selves defined by patient status, to new selves, with new perspectives

Numerical Calculation of Coherent Synchrotron Radiation Effects Using TraFiC4

Coherent synchrotron radiation (CSR) occurs when short bunches travel on strongly bent trajectories. Its effects on high-quality beams can be severe and are well understood qualitatively. For quantitative results, however, one has to rely on numerical methods. There exist several simulation codes utilizing different approaches. We describe in some detail the code TraFiC4 developed at DESY for design and analysis purposes, which approaches the problem from first principles and solves the equations of motion either perturbatively or self-consistently. We present some calculational results and comparison with experimental data. Also, we give examples of how the code can be used to design beamlines with minimal emittance growth due to CSR

The Unsuspecting CAM User: Cancer patients and the changing nature of holistic health

The number of cancer patients using complementary and alternative medicine (CAM) in the United States is growing, yet little is known about the meaning these activities have for users. Current literature supports the assumption that stigma surrounding CAM and holistic health practices are responsible for the reluctance of many cancer patients to self-identify as CAM users. This study explored the frequency of use, and familiarity with CAM among 25 female patients at a Midwestern oncology clinic. Findings suggest that patients need to be asked about CAM use multiple times and in multiple formats to gain an accurate assessment. Also, the assumptions about stigma may no longer be the reason patients are less than forthcoming about CAM use. The rise of integrative medicine and shifting boundaries of the holistic health movement may be equally, or in some cases, more responsible for the reluctance for CAM users to self-identify

Complete assessment of elastic properties of trabecular bone architecture from 3D reconstruction images

A method is presented that allows for a complete mechanical evaluation of trabecular bone architecture directly from three-dimensional computer reconstruction images. With this method, the reconstruction images are used as a basis for microstructural FE-analyses. From the results of these analyses the full stiffness matrix of bone specimens is obtained, using a standard mechanics approach. An optimization procedure is then used to find the best orthotropic representation and principal directions of this matrix. The method is demonstrated here relative to two trabecular bone specimens. With the development of in vivo reconstructions and the methods demonstrated here, even in vivo measurements will be possibl

Parallel Simulation Algorithms for the Three Dimensional Strong-Strong Beam-Beam Interaction

The strong-strong beam-beam effect is one of the most important effects limiting the luminosity of ring colliders. Little is known about it analytically, so most studies utilize numeric simulations. The two-dimensional realm is readily accessible to workstation-class computers (cf.,e.g.,[1, 2]), while three dimensions, which add effects such as phase averaging and the hourglass effect, require vastly higher amounts of CPU time. Thus, parallelization of three-dimensional simulation techniques is imperative; in the following we discuss parallelization strategies and describe the algorithms used in our simulation code, which will reach almost linear scaling of performance vs. number of CPUs for typical setups

The role of trabecular architecture in the anisotropic mechanical properties of bone

As yet, no unique relationship between mechanical and structural parameters has been established for trabecular bone. A possible explanation for the variability in the relationships obtained so far is that the results of mechanical tests represent more parameters than those of trabecular morphology alone. In the present study, the results of such a mechanical test are compared to results of a numerical experiment, from which the isolated mechanical role of the trabecular architecture of a bone specimen is obtained. A mechanically tested bone specimen was reconstructed in a computer and converted to a microstructural FE-model. The results of experiment and FE-simulation were, obviously, not identical. It is hypothesized that experimental artifacts are the most important factors affecting the mechanical test results, thus causing variability in the relationships. More accurate relationships are expected when these artifacts can be excluded, for example, by using microstructural FE-models

Occurrence and function of enzymes for lignocellulose degradation in commercial Agaricus bisporus cultivation

The white button mushroom Agaricus bisporus is economically the most important commercially produced edible fungus. It is grown on carbon- and nitrogen-rich substrates, such as composted cereal straw and animal manure. The commercial mushroom production process is usually performed in buildings or tunnels under highly controlled environmental conditions. In nature, the basidiomycete A. bisporus has a significant impact on the carbon cycle in terrestrial ecosystems as a saprotrophic decayer of leaf litter. In this mini-review, the fate of the compost plant cell wall structures, xylan, cellulose and lignin, is discussed. A comparison is made from the structural changes observed to the occurrence and function of enzymes for lignocellulose degradation present, with a special focus on the extracellular enzymes produced by A. bisporus. In addition, recent advancements in whole genome level molecular studies in various growth stages of A. bisporus in compost are reviewed.Peer reviewe
