More information about the Board’s work is available in the agendas, minutes, reports and press releases on the website, www.medicalboard.iowa.gov, and the Board’s page on Facebook. Much has been accomplished in the past year, but much more remains to be done. The Board looks forward to the many challenges that lie ahead and will continue to strengthen and enhance services to the public and licensees. I am very proud of the staff and Board members and their commitment to excellent service to the citizens of Iowa.

2011 Energy Independence Plan

Iowa has experienced remarkable progress in the past four years as the state has pursued a vision of becoming the nation’s energy leader. One of the most profound changes over this time has been a richer understanding of the economic future that can be created in Iowa by adding “Made in Iowa” alternatives to our nation’s energy mix. Built around a strong commitment to transforming our economy through innovation, collaboration, and implementation in the energy industry, the role of the Office of Energy Independence (Office) is to bring together the essential prerequisites for maintaining the long-term health and economic growth of our state. What is clearer than ever before is Iowa cannot achieve success if any entity chooses to pursue these goals independently. Rather, success requires that we consistently work to achieve our goals through integrated initiatives that place a high priority on moving us forward simultaneously, and on multiple fronts. Success is what our citizens expect from a leading state in the energy industry whose actions carry such far-reaching implications for the economy and the environment.

Inside IPERS and Pensioners’ Post, Winter 2004-2005

I am pleased to send you this special edition newsletter, which includes a fi nancial summary on pages 2 and 3. Providing you fi nancial and performance information refl ects my commitment to accountability. IPERS’ performance continues to be strong, as does the commitment of the Governor, Legislature, employers, members, the Investment Board, the Benefi ts Advisory Committee (BAC), and staff to maintaining a good retirement plan. Unfortunately, IPERS’ good performance and everyone’s commitment does not eliminate the need for a contribution rate increase. There are many reasons for this. We must make up for losses from the recent bear markets. Also, our retirees are living longer; therefore, they are drawing pensions longer.

Nuclear receptor PPARS function in stem cell differentiation and bone physiology

In adult, bone remodeling is a permanent process, reaching an annual turnover of about 10% of the skeleton. Bone remodeling requires the sequential and coordinated actions of the hematopoietic origin osteoclasts, to remove bone and the mesenchymal origin osteoblasts to replace it. An increased level of bone resorption is the primary cause of age-related bone loss often resulting in osteopenia, and is the major cause of osteoporosis.¦Peroxisome proliferator-activated receptors (PPARs), which are expressed in three isotypes, PPARa, PPARp and PPARy, are ligand-activated transcription factors that control many cellular and metabolic processes, more particularly linked to lipid metabolism. In bone, previous works has shown that PPARy inhibits osteogenesis by favoring adipogenesis from common mesenchymal progenitors. In addition, the pro-osteoclastogenesis activity of PPARy results in an increased bone resorption. Accordingly, treatment with PPARy agonist such as the anti-diabetic drug TZD causes bone loss and accumulation of marrow adiposity in mice as well as in postmenopausal women. The aim of the present thesis work was to elucidate the PPARs functions in bone physiology.¦The initial characterization of the PPARP" bone phenotype mainly revealed a decreased BMD. In vitro studies exploring the potency of mesenchymal stem cells to differentiate in osteoblast showed no differences depending on the genotype. However, we could demonstrate an effect of PPARp in partially inhibiting osteoclastogenesis. These results are further sustained by a study made in collaboration with the group of Dr Kronke, which showed an impressive protection against ovariectomy-generated bone loss when the females are treated with a PPARp agonist.¦Observations in PPARy null mice are more complex. The lab has recently been able to generate mice carrying a total deletion of PPARy. Intriguingly, the exploration of the bone phenotype of these mice revealed paradoxical findings. Whereas short bones such as vertebrae exhibit an elevated BMD as expected, long bones (tibia and femur) are clearly osteoporotic. According to their activity when set in culture, osteoblast differentiation normally occurs. Indeed the phenotype can be mainly attributed to a high density of osteoclasts in the cortical bone of PPARy null mice, associated to large bone resorption areas.¦Our explorations suggest a mechanism that involves regulatory processes linking osteoclastogenesis to adipogenesis, the latter being totally absent in PPARy null mice. Indeed, the lack of adipose tissue creates a favorable niche for osteoclastogenesis since conditioned medium made from differentiated adipocyte 3T3L1 inhibited osteoclastogenesis from both PPARy-/- and WT cells. Thus, adipokines deficiency in PPARy-/- mice contributes to de- repress osteoclastogenesis. Using specific blocking antibody, we further identified adiponectin as the major player among dozens of adipokines. Using flow cytometry assay, we explored the levels at which the osteoclastic commitment was perturbed in the bone marrow of PPARy-/- mice. Intriguingly, we observe a general decrease for hematopoietic stem cell and lineage progenitors but increased proportion of osteoclast progenitor in PPARy-/- bone marrow. The general decrease of HSC in the bone marrow is however largely compensated by an important extra-medullary hematopoeisis, taking place in the liver and in the spleen.¦These specific characteristics emphasize the key role of PPARy on a cross road of osteogenesis, adipogenesis and hematopoiesis/osteoclastogenesis. They underline the complexity of the bone marrow niche, and demonstrate the inter-dependance of different cell types in defining bone homeostasis, that may be overseen when experimental design single out pure cell populations.¦Chez l'adulte, même après la fin de la croissance, le renouvellement des os se poursuit et porte sur environ 10% de l'ensemble du squelette adulte, par année. Ce renouvellement implique à la fois des mécanismes séquentiels et coordonnés des ostéoclastes d'origine hématopoïetique, qui dégradent l'os, et des ostéoblastes d'origine mésenchymale, qui permettent la régénération de l'os. La perte en densité osseuse due à l'âge entraîne un fort niveau de résorption, conduisant souvent à une ostéopénie, elle-même cause de l'ostéoporose.¦Les trois isotypes PPAR (Peroxisome proliferator-activated receptor, PPARa, PPARp, et PPARy) sont des récepteurs nucléaires qui contrôlent de nombreux mécanismes cellulaires et métaboliques, plus particulièrement liés au métabolisme lipidique. Au niveau osseux, des travaux précédents ont montré que PPARy inhibe l'ostéoblastogenèse en favorisant la formation d'adipocytes à partir de la cellule progénitrice commune. De plus, l'activité pro- ostéoclastogénique de PPARy induit une résorption osseuse accrue. Condormément à ces observations, les patients diabétiques traités par les thiazolidinediones qui agissent sur PPARy, ont un risque accrue d'ostéoporose liée à une perte osseuse accrue et un accroissement de l'adiposité au niveau de la moelle osseuse. Dans ce contexte, l'objectif de mon travail de thèse a été d'élucider le rôle des PPAR dans la physiologie osseuse, en s'appuyant sur le phénotype des souris porteuses de mutation pour PPAR.¦La caractérisation initiale des os des souris porteuses d'une délétion de ΡΡΑΕφ a principalement révélé une diminution de la densité minérale osseuse (DMO). Alors que l'ostéogenèse n'est pas significativement altérée chez ces souris, l'ostéoclastogenèse est elle augmentée, suggérant un rôle modérateur de ce processus par ΡΡΑΕΙβ. Ces résultats sont par ailleurs soutenus par une étude menée par le groupe du Dr Krônke en collaboration avec notre groupe, et qui monte une protection très importante des souris traitées par un activateur de PPARP contre l'ostéoporose provoquée par l'ovariectomie.¦Les observations concernant PPARy donnent des résultats plus complexes. Le laboratoire a en effet été capable récemment de générer des souris portant une délétion totale de PPARy. Alors que les os courts chez ces souris présentent une augmentation de la DMO, comme attendu, les os longs sont clairement ostéoporotiques. Ce phénotype corrèle avec une densité élevée d'ostéoclastes dans l'os cortical de ces os longs. Deux processus semblent contribuer à ce phénotype. En premier lieu, nous démontrons qu'un milieu conditionné provenant de cultures de cellules 3T3-L1 différenciées en adipocytes contiennent une forte activité inhibitrice d'osteoclastogenesis. L'utilisation d'anticorps neutralisant permet d'identifier l'adiponectine comme l'un des facteurs principaux de cette inhibition. Les souris PPARy étant totalement dépourvues d'adipocytes et donc de tissu adipeux, la sécrétion locale d'adiponectine dans la moelle osseuse est donc également absente, entraînant une désinhibition de l'ostéoclastogenèse. En second lieu, des analyses par FACS révèle une proportion accrue des cellules progénitrices d'ostéoclastes dans la moelle osseuse. Cela s'accompagne par une diminution globale des cellules souches hématopoïétiques, qui est cependant largement compensée par une importante hématopoëise extra-médullaire, dans le foie comme dans la rate.¦L'ensemble de notre travail montre toute l'importance de PPARy au carrefour de l'ostéogenèse, adipogenèse, et hématopoëise/osteoclastogenèse. Il souligne la complexité de la niche que représente la moelle osseuse et démontre l'inter-dépendance des différents types cellulaires définissant l'homéostasie osseuse, complexité qui peut facilement être masqué lorsque le travail expérimental se concentre sur le comportement d'un type cellulaire donné.

HRM Practices, Intrinsic Motivators, and Organizational Performance in the Public Sector

This article aims to determine the impact of human resource management (HRM) practices on public service motivation (PSM) and organizational performance. Based on a survey of Swiss cantonal public employees (N = 3,131), this study shows that several HRM practices may be considered as organizational antecedents of PSM and strong predictors of perceived organizational performance. Fairness, job enrichment, individual appraisal, and professional development are HRM practices that are positively and significantly associated with PSM and perceived organizational performance. Moreover, these results suggest that HRM practices are stronger predictors than either PSM or organizational commitment when explaining the individual perception of organizational performance.

Iowa Plan for Energy Independence, 2007

Iowa’s first annual Energy Independence Plan kicks off a new era of state leadership in energy transformation. Supported by Governor Chet Culver, Lieutenant Governor Patty Judge, and the General Assembly, the Office of Energy Independence was established in 2007 to coordinate state activities for energy independence. The commitment of the state to lead by example creates opportunities for state government to move boldly to achieve its goals, track its progress, measure the results, and report the findings. In moving to energy independence, the active engagement of every Iowan will be sought as the state works in partnership with others in achieving the goals. While leading ongoing efforts within the state, Iowa can also show the nation how to effectively address the critical, complex challenges of shifting to a secure energy future of affordable energy, cost-effective efficiency, reliance on sustainable energy, and enhanced natural resources and environment. In accordance with House File 918, “the plan shall provide cost effective options and strategies for reducing the state’s consumption of energy, dependence on foreign sources of energy, use of fossil fuels, and greenhouse gas emissions. The options and strategies developed in the plan shall provide for achieving energy independence from foreign sources of energy by the year 2025.” Energy independence is a term which means different things to different people. We use the term to mean that we are charting our own course in the emerging energy economy. Iowa can chart its own course by taking advantage of its resources: a well-educated population and an abundance of natural resources, including rich soil, abundant surface and underground water, and consistent wind patterns. Charting our own course also includes further developing our in-state industry, capturing renewable energy, and working toward improved energy efficiency. Charting our own course will allow Iowa to manage its economic destiny while protecting our environment, while creating new, “green collar” industries in every corner of Iowa. Today Iowa is in a remarkable position to capitalize on the current situation globally and at home. Energy drives the economy and has impacts on the environment, undeniable links that are integral for energy security and independence. With the resources available within the state, the combination of significant global changes in energy and research leading to new technologies that continue to drive down the costs of sustainable energy, Iowa can take bold strides toward the goal of energy independence by 2025. The Office of Energy Independence, with able assistance from hundreds of individuals, organizations, agencies, and advisors, presents its plan for Iowa’s Energy Independence.

Distinct levels in Pom1 gradients limit Cdr2 activity and localization to time and position division.

Where and when cells divide are fundamental questions. In rod-shaped fission yeast cells, the DYRK-family kinase Pom1 is organized in concentration gradients from cell poles and controls cell division timing and positioning. Pom1 gradients restrict to mid-cell the SAD-like kinase Cdr2, which recruits Mid1/Anillin for medial division. Pom1 also delays mitotic commitment through Cdr2, which inhibits Wee1. Here, we describe quantitatively the distributions of cortical Pom1 and Cdr2. These reveal low profile overlap contrasting with previous whole-cell measurements and Cdr2 levels increase with cell elongation, raising the possibility that Pom1 regulates mitotic commitment by controlling Cdr2 medial levels. However, we show that distinct thresholds of Pom1 activity define the timing and positioning of division. Three conditions-a separation-of-function Pom1 allele, partial downregulation of Pom1 activity, and haploinsufficiency in diploid cells-yield cells that divide early, similar to pom1 deletion, but medially, like wild-type cells. In these cells, Cdr2 is localized correctly at mid-cell. Further, Cdr2 overexpression promotes precocious mitosis only in absence of Pom1. Thus, Pom1 inhibits Cdr2 for mitotic commitment independently of regulating its localization or cortical levels. Indeed, we show Pom1 restricts Cdr2 activity through phosphorylation of a C-terminal self-inhibitory tail. In summary, our results demonstrate that distinct levels in Pom1 gradients delineate a medial Cdr2 domain, for cell division placement, and control its activity, for mitotic commitment.

France's Charter for the Environment : of Presidents, Principles and Environmental Protection

France amended its constitution in 2005 to include a Charter for the Environment. The Charter lays out France's commitment to supporting the right to a 'balanced environment'. This article first traces the Charter's origins to a legacy-building presidential initiative. Jacques Chirac decided to invest in a neglected policy domain in which his own majority had shown little interest. He was obliged to intervene repeatedly in order to bring this project to a successful conclusion. In doing so, he staked out environmental affairs as an area of potential presidential supremacy. Next, the content of the Charter is examined. In this document, French traditions of universalism come together with an international movement for anticipatory environmental protection. This is reflected in the constitutionalisation of the precautionary principle, which emerged as the most controversial part of the Charter. The debates this provoked tended to caricature a risk-management principle whose meaning has been carefully refined to forestall objections. Finally, the Charter's potential efficacy is analysed. The post-Charter record of legislative and judicial activity concerning the environment is meagre, but not wholly inauspicious.

Some of the early events underlying Th2 cell maturation and susceptibility to Leishmania major infection in BALB/c mice.

The first experimental evidence for the development of polarized CD4+ Th1 and Th2 responses in vivo has been obtained using the murine model of infection with Leishmania major, an intracellular parasite of macrophages in their vertebrate host. Genetically determined resistance and susceptibility to infection with this parasite have been clearly demonstrated to result from the development of polarized Th1 and Th2 responses, respectively. Using this model system, the dominant role of cytokines in the induction of polarized CD4+ responses has been validated in vivo. The requisite role of IL-4 in mediating both Th2 differentiation and susceptibility to infection in BALB/c mice has directed interest towards the search for evidence of IL-4 production early after infection and identification of its cellular source. We have been able to demonstrate a burst of IL-4 production in susceptible BALB/c mice within the first day of infection with L. major and could establish that this rapidly produced IL-4 instructed Th2 lineage commitment of subsequently activated CD4+ T cells and stabilized this commitment by downregulating IL-12 Rbeta2 chain expression, resulting in susceptibility to infection. Strikingly, this early IL-4 response to infection resulted from the cognate recognition of a single epitope in a distinctive antigen, LACK, from this complex microorganism by a restricted population of CD4+ T cells that express Vbeta4-Valpha8 T cell receptors.

Which change talk dimensions are associated with subsequent drinking among young men receiving a brief motivational intervention in a non-clinical setting?

Background: Patient change talk (CT) during brief motivational interventions (BMI) has been linked with subsequent changes in drinking in clinical settings but this link has not been clearly established among young people in non-clinical populations. Objective: To determine which of several CT dimensions assessed during an effective BMI delivered in a non-clinical setting to 20-year old men are associated with drinking 6 months later. Methods: Of 125 individuals receiving a face-to-face BMI session (15.8 ± 5.4 minutes), we recorded and coded a subsample of 42 sessions using the Motivational Interviewing Skill Code 2.1. Each patient change talk utterance was categorized as `Reason´, `Ability´, `Desire´, `Need´, `Commitment´, `Taking steps´, or `Other´. Each utterance was graded according to its strength (absolute value from 1 to 3) and direction (i.e. towards (positive sign) or away (negative sign) from change/in favor of status quo). `Ability´, `Desire´, and `Need´ to change (`ADN´) were grouped together since these codes were too scarce to conduct analyses. Mean strength scores over the entire session were computed for each dimension and later dichotomized in towards change (i.e. mean core > 0) and away from change/in favor of status quo. Negative binomial regression models were used to assess the relationship between CT dimensions and drinking 6 months later, adjusting for drinking at baseline. Results: Compared to subjects with a `Taking steps´ score away from change/in favor of status quo, subjects with a positive `Taking steps´ score reported significantly less drinking 6 months later (Incidence Rate Ration [IRR] for drinks per week: 0.56, 95% Confidence Interval [CI] 0.31, 1.00). IRR (95%CI) for subjects with a positive `ADN´ score was 0.58, (0.32, 1.03). For subjects with a positive `Reason´, `Commitment´, and `Other´ scores, IRR (95%CI) were 1.28 (0.77; 2.12) 1.63 (0.85; 3.14) and 1.03 (0.61; 1.72), respectively. Conclusion: A change talk dimension reflecting steps taken towards change (`Taking steps´) is associated with less drinking 6 months later among young men receiving a BMI in a non-clinical setting. Encouraging patients to take steps towa change may be a worthy objective for clinicians and may explain BMI efficacy.

Molecular genetic framework for protophloem formation.

The phloem performs essential systemic functions in tracheophytes, yet little is known about its molecular genetic specification. Here we show that application of the peptide ligand CLAVATA3/EMBRYO SURROUNDING REGION 45 (CLE45) specifically inhibits specification of protophloem in Arabidopsis roots by locking the sieve element precursor cell in its preceding developmental state. CLE45 treatment, as well as viable transgenic expression of a weak CLE45(G6T) variant, interferes not only with commitment to sieve element fate but also with the formative sieve element precursor cell division that creates protophloem and metaphloem cell files. However, the absence of this division appears to be a secondary effect of discontinuous sieve element files and subsequent systemically reduced auxin signaling in the root meristem. In the absence of the formative sieve element precursor cell division, metaphloem identity is seemingly adopted by the normally procambial cell file instead, pointing to possibly independent positional cues for metaphloem formation. The protophloem formation and differentiation defects in brevis radix (brx) and octopus (ops) mutants are similar to those observed in transgenic seedlings with increased CLE45 activity and can be rescued by loss of function of a putative CLE45 receptor, BARELY ANY MERISTEM 3 (BAM3). Conversely, a dominant gain-of-function ops allele or mild OPS dosage increase suppresses brx defects and confers CLE45 resistance. Thus, our data suggest that delicate quantitative interplay between the opposing activities of BAM3-mediated CLE45 signals and OPS-dependent signals determines cellular commitment to protophloem sieve element fate, with OPS acting as a positive, quantitative master regulator of phloem fate.
