Managed Care and the Growth of Medical Expenditures
Authors: Cutler David M. , Sheiner Louise
Published: November 2006

We use data across states to examine the relation between HMO enrollment and medical spending. We find that increased managed care enrollment significantly reduces hospital cost growth. Although increased spending on physicians offsets some of this effect, we generally find a significant reduction in total spending as well. In analyzing the sources of hospital cost reductions, we find preliminary evidence that managed care has reduced the diffusion of medical technologies. States with high managed care enrollment were technology leaders in the early 1980s; by the early 1990s those states were only average in their acquisition of new technologies. This finding suggests managed care may significantly affect the long-run growth of medical spending.
Persistence of Medicare Expenditures among Elderly Beneficiaries
Authors: Garber Alan M. , MaCurdy Thomas E. , McClellan Mark B.
Published: November 2006

The highly uneven distribution of Medicare payments among elderly beneficiaries, combined with the predictability of some of the expenditures, poses several challenges to the Medicare program. We present information about the distribution of Medicare expenditures among beneficiaries in specific years, accompanied by new evidence on the extent to which Medicare payments for the care of individual beneficiaries persist over long time periods. Our analysis is based on a longitudinal population of Medicare enrollees during the years 1987 to 1995. We find that high-cost users accounted for a disproportionate share of the growth of Medicare Part A (hospital) payments during this period, but that an increase in the number of beneficiaries using covered services was largely responsible for the growth of Medicare Part B payments. Few beneficiaries are in the highest-cost categories for multiple years; the high mortality rates of individuals who use medical services heavily, whether the expenditures occur in one year or repeatedly, limits the extent of expenditure persistence. Even among survivors, it is unusual to remain in the highest-cost categories for multiple years. Nevertheless, individuals with high expenditures in one year are likely to have higher than average expenditures in other years, and expenditures are highly skewed even over a period of nine years. Any policy to reform Medicare will need to accommodate expenditure persistence to provide adequate coverage for all beneficiaries.
Two servers in series, studied in terms of a Markov renewal branching process
Authors: Neuts Marcel F.
Published: November 2006

This paper discusses the transient and limiting behavior of a system of queues, consisting of two service units in tandem in which the second unit has finite capacity. When the second unit reaches full capacity, a phenomenon termed “blocking” occurs. A wide class of rules to resolve blocking is defined and studied in a unified way.

The input to the first unit is assumed to be Poisson, the service times in the first unit are independent with a general, common distribution. When the system is not blocked, the second unit releases its customers according to a state-dependent, death process.

The analysis of the time-dependence relies heavily on several imbedded Markov renewal processes. In particular, the analog of the busy period for theM/G/1 queue is modeled here as a “Markov renewal branching process”. The study of this process requires the definition of a class of matrix functions which generalizes some classical definitions of matrix function. In terms of these “matrix functions” we are led to consider functional iterates and a matrix analog of Takács' functional equation for the transform of the distribution of the busy period in theM/G/1 model.

We further discuss the joint distribution of the queue lengths in units I and II and its marginal and limiting distributions.

A final section is devoted to an informal discussion on how the numerical analysis of this system of queues may be organized.
In vitro metabolism of ciclesonide in human nasal epithelial cells
Authors: Sato Hideyuki , Nave Ruediger , Nonaka Takashi , Mochizuki Tsutomu , Takahama Shigehiro , Kondo Shiro
Published: November 2006

Ciclesonide, a corticosteroid in development for allergic rhinitis, is converted to the pharmacologically active metabolite, desisobutyryl‐ciclesonide (des‐CIC), and des‐CIC is subsequently esterified with fatty acids. Various experiments were performed to investigate ciclesonide metabolism in human nasal epithelial cells (HNEC). Human nasal epithelial cells were incubated with (a) 0.1 µM ciclesonide for 1 h and medium without ciclesonide for up to 24 h, (b) esterase inhibitors for 0.5 h followed by 5 µM ciclesonide for 6 h, or (c) 1 µM des‐CIC for 6 h followed by medium without des‐CIC for up to 24 h. Ciclesonide, des‐CIC and des‐CIC fatty acid conjugate concentrations were determined by high‐performance liquid chromatography with tandem mass spectrometry. The amount of ciclesonide in HNEC decreased approximately 93‐fold from 0.5 to 24 h. In contrast, des‐CIC was present at constant levels throughout the post‐treatment period. Furthermore, fatty acid conjugates of des‐CIC were retained in HNEC up to 24 h post‐treatment. Carboxylesterase and cholinesterase inhibitors decreased ciclesonide metabolism ⩾50%. The total amounts of des‐CIC fatty acid conjugates decreased and the extracellular amounts of des‐CIC increased with time. In conclusion, ciclesonide was rapidly converted to des‐CIC by carboxylesterases and cholinesterases, and des‐CIC underwent reversible fatty acid conjugation in HNEC.

The blood/vascular system in a phylogenetic perspective
Authors: Hartenstein Volker , Mandal Lolitika
Published: November 2006

The genetically and experimentally accessible organs of Drosophila, such as the heart or blood‐forming tissues, have become a fertile ground for systematic projects of gene discovery and for functional studies of gene networks and signaling pathways. One argument justifying this approach is the often‐tacit assumption that clear‐cut homologies can be established between the Drosophila organs and their vertebrate counterparts. Here we investigate this assumption by surveying pertinent aspects of vascular structure and development in different invertebrate phyla, in the hope that this information will help to reveal the ancestral condition of the vascular system. Evolutionary scenarios that derive the structure of the cardiovascular system of extant animal taxa from the ancestral condition will be used to qualify hypotheses regarding homologies that are based on molecular similarities.

Born to bind: the BTB protein–protein interaction domain
Authors: Perez‐Torrado Roberto , Yamada Daisuke , Defossez Pierre‐Antoine
Published: November 2006

The BTB domain is a protein–protein interaction motif that is found throughout eukaryotes. It determines a unique tri‐dimensional fold with a large interaction surface. The exposed residues are highly variable and can permit dimerization and oligomerization, as well as interaction with a number of other proteins. BTB‐containing proteins are numerous and control cellular processes that range from actin dynamics to cell‐cycle regulation. Here, we review findings in the field of transcriptional regulation to illustrate how the high variability of the BTB has allowed related transcription factors to evolve different functional abilities. We then report how recent work has showed that, in spite of their high sequence divergence and apparently unrelated functions, many BTB‐containing proteins have at least one shared role: the recruitment of degradation targets to E3 ubiquitin ligase complexes. Taken together, these findings illustrate diverse and convergent functions of a versatile protein–protein interaction domain. BioEssays 28: 1194–1202, 2006. © 2006 Wiley Periodicals, Inc.
Telomere dysfunction: a new player in radiation sensitivity
Authors: Genescà Anna , Martín Marta , Latre Laura , Soler David , Pampalona Judit , Tusell Laura
Published: November 2006

Human individuals often exhibit important differences in their sensitivity to ionising radiation. Extensive literature links radiation sensitivity with impaired DNA repair which is due to a lack of correct functioning in many proteins involved in DNA‐repair pathways and/or in DNA‐damage checkpoint responses. Given that ionising radiation is an important and widespread diagnostic and therapeutic tool, it is important to investigate further those factors and mechanisms that underlie individual radiosensitivity. Recently, evidence is accumulating that telomere function may well be involved in cellular and organism responses to ionising radiation, broadening still further the currently complex and challenging scenario.

The molecular basis of neurosensory cell formation in ear development: a blueprint for hair cell and sensory neuron regeneration?
Authors: Fritzsch Bernd , Beisel Kirk W. , Hansen Laura A.
Published: November 2006

The inner ear of mammals uses neurosensory cells derived from the embryonic ear for mechanoelectric transduction of vestibular and auditory stimuli (the hair cells) and conducts this information to the brain via sensory neurons. As with most other neurons of mammals, lost hair cells and sensory neurons are not spontaneously replaced and result instead in age‐dependent progressive hearing loss. We review the molecular basis of neurosensory development in the mouse ear to provide a blueprint for possible enhancement of therapeutically useful transformation of stem cells into lost neurosensory cells. We identify several readily available adult sources of stem cells that express, like the ectoderm‐derived ear, genes known to be essential for ear development. Use of these stem cells combined with molecular insights into neurosensory cell specification and proliferation regulation of the ear, might allow for neurosensory regeneration of mammalian ears in the near future.

Molecular mechanisms involved in Ras inactivation: the annexin A6–p120GAP complex
Authors: Grewal Thomas , Enrich Carlos
Published: November 2006

In mammalian cells, a complex network of signaling pathways tightly regulates a variety of cellular processes, such as proliferation and differentiation. New insights from one of the most‐important signaling cascades involved in oncogenesis, the Ras–Raf–MAPK pathway, suggest that the subcellular localisation and assembly of signaling modules of this pathway is crucial to control the biological response. This commonly requires membrane targeting events that are mediated by adaptor/scaffold proteins. Of particular interest is the translocation and complex formation of GTPase‐activating proteins (GAPs), such as p120GAP, at the plasma membrane to inactivate Ras. Recent studies indicate that one member of the annexin family, annexin A6 acts as a targeting protein for p120GAP. This review discusses how annexin A6 modulates the involvement of negative regulators of the Ras–Raf–MAPK pathway contributing to Ras inactivation.

Evolution at the host–retrovirus interface
Authors: Gifford Robert J.
Published: November 2006

Retroviruses are unusual amongst animal viruses in their capacity to integrate into host genomes and be transmitted vertically to host progeny. Vertebrate genomes contain numerous and diverse retrovirus‐derived sequences reflecting a long co‐evolutionary history during which genome invasion has occurred repeatedly, with wide‐ranging evolutionary consequences. Over the past 10 years, a detailed picture of retroviral diversity throughout vertebrate genomes has emerged, revealing striking and informative patterns that differ markedly across species. The power of these data to deliver far‐reaching insights into the biology and evolution of retroviruses has been significantly advanced by recent studies identifying ongoing genome invasion in wild populations,(1) and by the characterisation of conserved mechanisms of innate antiretroviral defence.(2,3) BioEssays 28: 1153–1156, 2006. © 2006 Wiley Periodicals, Inc.
Lhx2—decisive role in epithelial stem cell maintenance, or just the “tip of the iceberg”?
Authors: Tiede Stephan , Paus Ralf
Published: November 2006

Stem cell self renewal, maintenance and differentiation are influenced by the convergence of intrinsic cellular signals and extrinsic microenvironmental cues from the surrounding stem cell niche. However, the specific signals involved are often still poorly understood. This is also true for skin epithelial stem cells. Recently, by transcriptionally profiling of embryonic hair progenitors in mice, Rhee et al.1 have managed to define how murine hair follicle epithelial stem cells are specified and maintained in an undifferentiated state. These authors have identified Lhx2 as a transcription factor functionally positioned downstream of signals necessary to specify hair follicle stem cells such as p63 or NFκB, but upstream of signals like Wnt/β‐catenin, Bmp or Shh that are required to drive activated stem cells via the production of transient amplifying cells into terminal differentiation.

Hooking some stem‐group “worms”: fossil lophotrochozoans in the Burgess Shale
Authors: Butterfield Nicholas J.
Published: November 2006

The fossil record plays a key role in reconstructing deep evolutionary relationships through its documentation of the early diverging stem groups leading to extant phyla. In the middle Cambrian Burgess Shale, two famously problematic worms, Odontogriphus and Wiwaxia, have recently been reinterpreted as stem‐group molluscs based on their shared expression of a putative radula and putative ctenidia in Odontogriphus.1 More detailed analysis of these fossil structures, however, reveals pronounced anatomical and histological discrepancies with molluscan analogues, such that they are more reliably interpreted as primitive features of the superphylum Lophotrochozoa. In the absence of any obviously derived characters, Odontogriphus could be placed in the stem group of the Lophotrochozoa or on the stem of any of its constituent phyla, whereas the dorsal covering of chaetae in Wiwaxia identifies it as a stem‐group polychaete. Despite their close relationship, these two jawed, segmented worms could conceivably represent the early stages of two separate phyla. BioEssays 28: 1161–1166, 2006. © 2006 Wiley Periodicals, Inc.
Deeper into the maize: new insights into genomic imprinting in plants
Authors: Scott Rod J. , Spielman Melissa
Published: November 2006

Current models for regulation of parent‐specific gene expression in plants have been based on a small number of imprinted genes in Arabidopsis. These present repression as the default state, with expression requiring targeted activation. In general, repression is associated with maintenance methylation of cytosines, while no role has been found in Arabidopsis imprinting for de novo methylation—unlike the case in mammals. A recent paper1 both reinforces and challenges the model drawn from Arabidopsis. Methylation patterns of two imprinted loci in maize were tracked from gametes to offspring, enabling an exploration of the timing of imprinting. For one gene, fie1, the results were as expected: parent‐specific methylation patterns were inherited from the three types of gamete: egg, central cell and sperm. The behaviour of fie2, however, was a surprise: no alleles were methylated in the gametes, although paternally contributed fie2 is methylated and silent in the endosperm, indicating that, in some cases, plant imprinting requires de novo DNA methylation. This work significantly broadens our understanding of plant imprinting and points to a greater diversity in imprinting mechanisms than has previously been appreciated.

Sorting and pooling strategy: A novel tool to map a virus proteome for CD8 T‐cell epitopes
Authors: Ay Bernhard , Streitz Mathias , Boisguerin Prisca , Schlosser Andreas , Mahrenholz Carsten C. , Schuck Sebastian D. , Kern Florian , Volkmer Rudolf
Published: November 2006

Human cytomegalovirus (CMV) is a major cause of morbidity in immunocompromised individuals. However, no efficient vaccine has been developed to date. Identification of T‐cell target proteins and epitopes is crucial not only for developing a successful immunization strategy, but also for new approaches using adoptive transfer of antigen‐specific T‐cells. The CMV genome has more than 200 open reading frames potentially coding for as many proteins. Here, we describe a robust, fast, and simple SPOT synthesis strategy, which allowed us to micro‐synthesize every possible CD8 T‐cell epitope in the entire potential CMV proteome. So far, 9069 of these peptides have been tested in an ex vivo T‐cell stimulation assay. As well as confirming a number of previously known epitopes, we identified several new ones. © 2006 Wiley Periodicals, Inc. Biopolymers (Pept Sci) 88:64–75, 2007.

A 2D–3D integrated tabletop environment for multi‐user collaboration
Authors: Nakashima Kousuke , Machida Takashi , Kiyokawa Kiyoshi , Takemura Haruo
Published: November 2006

This paper proposes a novel tabletop display system for natural communication and flexible information sharing. The proposed system is specifically designed to integrate two‐dimensional (2D) and three‐dimensional (3D) user interfaces by using a multi‐user stereoscopic display, IllusionHole. The proposed system takes awareness into consideration and provides both 2D and 3D information and user interfaces. On the display, a number of standard Windows desktop environments are provided as personal workspaces, as well as a shared workspace with a dedicated graphical user interface. In the personal workspaces, users can simultaneously access existing applications and data, and exchange information between personal and shared workspaces. In this way, the proposed system can seamlessly integrate personal, shared, 2D, and 3D workspaces with conventional user interfaces and effectively support communication and information sharing. To demonstrate the capabilities of the proposed display system, a modeling application was implemented. A preliminary experiment confirmed the effectiveness of this system.

Statistical signatures used with principal component analysis for fault detection and isolation in a continuous reactor
Authors: Miller John P.
Published: November 2006

Principal component analysis (PCA) is a technique widely used in industrial process control for data analysis and reduction. A score discriminant can be used in conjunction with a PCA model to differentiate between the normal operating condition and an abnormal condition. To illustrate application of these analytical techniques, raw data is collected from a high fidelity simulation of a continuous chemical reactor for both the normal operating condition, and several different fault conditions. A PCA model and score discriminant are applied to analyze the raw data, but this approach does not reliably differentiate between all process conditions. To improve the differentiation, an alternative model is developed using the statistical signatures of mean and standard deviation, such as are computed in some present day intelligent field devices. The new PCA score discriminant model based on statistical signatures produces a much clearer differentiation between all process conditions. Copyright © 2006 John Wiley & Sons, Ltd.
Quality assessment of the results obtained by multivariate curve resolution analysis of multiple runs of gasoline blending processes
Authors: Jaumot Joaquim , Menezes José C. , Tauler Romà
Published: November 2006

This work presents a quality assessment study of the results obtained by multivariate curve resolution of multiple runs of gasoline blending processes. This evaluation is performed by noise propagation studies using resampling methods and by calculation of feasible bands due to rotational ambiguities. Results showed that combination of matrix augmentation and use of constraints strategies during alternating least squares optimization minimize both rotational ambiguities and error propagation effects in the resolved solutions. The proposed approach is tested for simulated and experimental data sets obtained in the study of blending processes of gasolines monitored by NIR spectroscopy.

Effects of pre‐processing of Raman spectra on in vivo classification of nutrient status of microalgal cells
Authors: Heraud Philip , Wood Bayden R. , Beardall John , McNaughton Don
Published: November 2006

Raman spectra were obtained from cells of the chlorophyte unicellular eukaryotic alga Dunaliella tertiolecta, which had been grown either under nutrient‐replete conditions or starved of nitrogen for 4 days. Spectra were rich in bands which could all be attributed to either chlorophyll a or β‐carotene. A cursory examination of the differences between the spectra of replete and starved cells indicated a decline in chlorophyll a and an increase in β‐carotene in chlorophytes. Unprocessed spectra showed pronounced baseline effects. A variety of pre‐processing techniques were used in an attempt to visualise the spectral, and hence chemical, differences in the transformed data and perform classification based upon these differences. Six types of spectral pre‐processing were compared: baseline correction with vector normalisation; Multiplicative Scatter Correction (MSC), Extended Multiplicative Signal Correction (EMSC); Standard Normal Variate (SNV); and vector normalised 1st and 2nd derivative spectra. Results for Soft Independent Modelling of Class Analogy (SIMCA) and Partial Least Squares (PLS) discriminant analysis were compared. All pre‐processing methods allowed spectral differences between N‐replete and N‐starved spectra to be visualised, with derivatives and EMSC scoring the lowest RMSEC and RMSEV values with PLS and also the best overall classification results. SIMCA was not suited to classifying the nutrient classes under any of the pre‐treatments, due to the small model distances involved. Copyright © 2006 John Wiley & Sons, Ltd.
An exploratory chemometric study of 1H NMR spectra of table wines
Authors: Larsen Flemming H. , van den Berg Frans , Engelsen Søren B.
Published: November 2006

In this paper an exploratory study of 40 table wines by proton nuclear magnetic resonance spectroscopy and chemometric region‐selection methods is presented. Several components of wine have been identified and quantified. It is demonstrated how signal alignment procedures were utilized to compensate for pH effects in the NMR spectra prior to the chemometric data modeling. The analysis included region selection by interval partial least squares for regression to reference data obtained from infrared spectroscopy. Accurate calibration models to the contents of ethanol, glycerol, lactic acid, methanol and malic acid were established. For the more general combined glucose/fructose infrared reference backwards interval partial least squares was introduced for optimal interval selection in calibration. The aim of the paper is to show how pre‐processing and region‐selection methods can assist in interpretation and quantification of chemical shift multiplets in 1H NMR spectra of complex biological systems. The extension to NMR metabolomics is straightforward. Copyright © 2006 John Wiley & Sons, Ltd.
