Iowa "50 States Project": A Review of the 1983 Code for Sexuality Discrimination, February 1984

The "50 States Project" is the name given to President Ronald D. Reagan;s 1981 pledge to encourage the fifty governors to initiate individual state projects to review their state Codes for unequal treatment of persons based upon sex. We believe that Iowa is the first state to complete this project. Project efforts in Iowa began in June of 1981, when the Governor Robert D. ray appointed Dr. Patricia L. Geadelmann, Chairperson on the Iowa commission on the Status of Women, as Iowa's 50 State Project representative. A 50 States planning committee was formed consisting of members from the Governor Ray's staff, the Iowa Commission on the Status of Women, and the Iowa Legislature. Various alternatives for reviewing the Iowa code and the Iowa Administrative Rules were studied and recommendations of the group were reported to Governor Terry E. Branstad prior to his inauguration.

New loci associated with birth weight identify genetic links between intrauterine growth and adult height and metabolism.

Birth weight within the normal range is associated with a variety of adult-onset diseases, but the mechanisms behind these associations are poorly understood. Previous genome-wide association studies of birth weight identified a variant in the ADCY5 gene associated both with birth weight and type 2 diabetes and a second variant, near CCNL1, with no obvious link to adult traits. In an expanded genome-wide association meta-analysis and follow-up study of birth weight (of up to 69,308 individuals of European descent from 43 studies), we have now extended the number of loci associated at genome-wide significance to 7, accounting for a similar proportion of variance as maternal smoking. Five of the loci are known to be associated with other phenotypes: ADCY5 and CDKAL1 with type 2 diabetes, ADRB1 with adult blood pressure and HMGA2 and LCORL with adult height. Our findings highlight genetic links between fetal growth and postnatal growth and metabolism.

Effective mass and dielectric constant mismatch effects in spherical multishell quantum dots

The role of effective mass and dielectric mismatches on chemical potentials and addition energies of many-electron multishell quantum dots (QDs) is explored within the framework of a recent extension of the spin density functional theory. It is shown that although the gross electronic density is located in the wells of these multishell QDs, taking position-dependent effective mass and dielectric constant into account can lead to the appearance of relevant differences in chemical potential and addition energies as compared to standard calculations in which the effective mass and the dielectric constant of the well is assumed for the whole multishell structure.

Plac8 is an inducer of C/EBPβ required for brown fat differentiation, thermoregulation, and control of body weight.

Brown adipocytes oxidize fatty acids to produce heat in response to cold or to excessive energy intake; stimulation of brown fat development and function may thus counteract obesity. Brown adipogenesis requires activation of the transcription factor C/EBPβ and recruitment of the zinc finger protein Prdm16, but upstream inducers of these proteins are incompletely defined. Here, we show that genetic inactivation of Plac8, a gene encoding an evolutionarily conserved protein, induces cold intolerance, and late-onset obesity, as well as abnormal morphology and impaired function of brown adipocytes. Using brown preadipocyte lines we show that Plac8 is required for brown fat differentiation, that its overexpression induces C/EBPβ and Prdm16, and that upon induction of differentiation Plac8 associates with C/EBPβ and binds to the C/EBPβ promoter to induce its transcription. Thus, Plac8 is a critical upstream regulator of brown fat differentiation and function that acts, at least in part, by inducing C/EBPβ expression.

Repeated sprinting on natural grass impairs vertical stiffness but does not alter plantar loading in soccer players.

This study aimed to determine changes in spring-mass model (SMM) characteristics, plantar pressures, and muscle activity induced by the repetition of sprints in soccer-specific conditions; i.e., on natural grass with soccer shoes. Thirteen soccer players performed 6 × 20 m sprints interspersed with 20 s of passive recovery. Plantar pressure distribution was recorded via an insole pressure recorder device divided into nine areas for analysis. Stride temporal parameters allowed to estimate SMM characteristics. Surface electromyographic activity was monitored for vastus lateralis, rectus femoris, and biceps femoris muscles. Sprint time, contact time, and total stride duration lengthened from the first to the last repetition (+6.7, +12.9, and +9.3%; all P < 0.05), while flight time, swing time, and stride length remained constant. Stride frequency decrease across repetitions approached significance (-6.8%; P = 0.07). No main effect of the sprint number or any significant interaction between sprint number and foot region was found for maximal force, mean force, peak pressure and mean pressure (all P > 0.05). Center of mass vertical displacement increased (P < 0.01) with time, together with unchanged (both P > 0.05) peak vertical force and leg compression. Vertical stiffness decreased (-15.9%; P < 0.05) across trials, whereas leg stiffness changes were not significant (-5.9%; P > 0.05). Changes in root mean square activity of the three tested muscles over sprint repetitions were not significant. Although repeated sprinting on natural grass with players wearing soccer boots impairs their leg-spring behavior (vertical stiffness), there is no substantial concomitant alterations in muscle activation levels or plantar pressure patterns.

Spatial weights : constructing weight-compatible exchange matrices from proximity matrices

Exchange matrices represent spatial weights as symmetric probability distributions on pairs of regions, whose margins yield regional weights, generally well-specified and known in most contexts. This contribution proposes a mechanism for constructing exchange matrices, derived from quite general symmetric proximity matrices, in such a way that the margin of the exchange matrix coincides with the regional weights. Exchange matrices generate in turn diffusive squared Euclidean dissimilarities, measuring spatial remoteness between pairs of regions. Unweighted and weighted spatial frameworks are reviewed and compared, regarding in particular their impact on permutation and normal tests of spatial autocorrelation. Applications include tests of spatial autocorrelation with diagonal weights, factorial visualization of the network of regions, multivariate generalizations of Moran's I, as well as "landscape clustering", aimed at creating regional aggregates both spatially contiguous and endowed with similar features.

Tobramycin exposure from active calcium sulfate bone graft substitute.

BACKGROUND: Bone graft substitute such as calcium sulfate are frequently used as carrier material for local antimicrobial therapy in orthopedic surgery. This study aimed to assess the systemic absorption and disposition of tobramycin in patients treated with a tobramycin-laden bone graft substitute (Osteoset® T). METHODS: Nine blood samples were taken from 12 patients over 10 days after Osteoset® T surgical implantation. Tobramycin concentration was measured by fluorescence polarization. Population pharmacokinetic analysis was performed using NONMEM to assess the average value and variability (CV) of pharmacokinetic parameters. Bioavailability (F) was assessed by equating clearance (CL) with creatinine clearance (Cockcroft CLCr). Based on the final model, simulations with various doses and renal function levels were performed. (ClinicalTrials.gov number, NCT01938417). RESULTS: The patients were 52 +/- 20 years old, their mean body weight was 73 +/- 17 kg and their mean CLCr was 119 +/- 55 mL/min. Either 10 g or 20 g Osteoset® T with 4% tobramycin sulfate was implanted in various sites. Concentration profiles remained low and consistent with absorption rate-limited first-order release, while showing important variability. With CL equated to CLCr, mean absorption rate constant (ka) was 0.06 h-1, F was 63% or 32% (CV 74%) for 10 and 20 g Osteoset® T respectively, and volume of distribution (V) was 16.6 L (CV 89%). Simulations predicted sustained high, potentially toxic concentrations with 10 g, 30 g and 50 g Osteoset® T for CLCr values below 10, 20 and 30 mL/min, respectively. CONCLUSIONS: Osteoset® T does not raise toxicity concerns in subjects without significant renal failure. The risk/benefit ratio might turn unfavorable in case of severe renal failure, even after standard dose implantation.

Molecular weight of hydroxyethyl starch : is there an effect on blood coagulation and pharmacokinetics ?

Résumé Fondement : le développement de solutions d'hydroxy-éthyl-amidons (HEAS) avec peu d'impact sur la coagulation sanguine, mais un effet supérieur sur la volémie, par comparaison aux HEAS couramment utilisés, est d'un grand intérêt clinique. Nous posons l'hypothèse que des solutions de haut poids moléculaire et de bas degré de substitution possèdent ces caractéristiques. Méthode : trente porcs ont été perfusés avec trois HEAS différents (20 ml/kg) de même degré de substitution (0.42) mais de poids moléculaire différent (130, 500 et 900 kDa). Une série de prélèvements sanguins ont été effectués sur 24 heures, sur lesquels des analyses de coagulation sanguine étaient effectuées par thromboélastographie et dosages plasmatiques. De plus, la concentration plasmatique ainsi que le poids moléculaire in vivo ont été déterminés, ainsi que des paramètres de pharmacocinétiques, ceci en se basant sur un modèle bi-compartimental. Résultats : les analyses de thromboélastographie et les tests de coagulation plasmatique n'ont pas démontré d'altération plus marquée de la coagulation sanguine après l'utilisation des solutions des HAES 500 et HAES 900, par comparaison avec celle de HAES 130. Par contre, les HAES 500 et HAES 900 ont présenté une plus grande aire sous la courbe (area under the curve), dans la relation concentration en fonction du temps [1542 (142) g min litre-1, p<0.001, 1701 (321) g min litre-1, p<0.001] par rapport au HAES 130 [1156 (223) g min litre-1]. La demi-vie alpha (t ½α) était plus longue pour les HAES 500 [53.8 (8.6) min, p<0.01] et HAES 900 [57.1 (12.3) min, p<0.01 ]que pour le HAES 130 [39.9 (10.7) min]. La demi-vie beta (t½β) était par contre similaire pour les trois types de HAES [de 332 (100) à 381 (63) min]. Conclusions : pour les HAES de bas degré de substitution, le poids moléculaire n'est pas un facteur clé en ce qui concerne l'altération de la coagulation. La persistance intravasculaire initialement plus longue des HAES de haut poids moléculaire et bas degré de substitution pourrait résulter dans un plus long effet volémique de ces substances. Abstract Background: The development of hydroxyethyl starches (HES) with low impact on blood coagulation but higher volume effect compared with the currently used HES solutions is of clinical interest. We hypothesized that high molecular weight, low-substituted HES might possess these properties. Methods: Thirty pigs were infused with three different HES solutions (20 ml kg-1) with the same degree of molar substitution (0.42) but different molecular weights (130, 500 and 900 kDa). Serial blood samples were taken over 24 h and blood coagulation was assessed by Thromboelastograph® analysis and analysis of plasma coagulation. In addition, plasma concentration and in vivo molecular weight were determined and pharmacokinetic data were computed based on a two-compartment model. Results: Thromboelastograph analysis and plasma coagulation tests did not reveal a more pronounced alteration of blood coagulation with HES 500 and HES 900 compared with HES 130. In contrast, HES 500 and HES 900 had a greater area under the plasma concentration-time curve [1542 (142) g min litre-1, P<0.001, 1701 (321) g min litre-1, P<0.001] than HES 130 [I 156 (223) g min litre-1] and alpha half life (t ½α) was longer for HES 500 [53.8 (8.6) min, P<0.01 ] and HES 900 [57. I (I 2.3) min, P<0.01 ] than for HES 130 [39.9 (I 0.7) min]. Beta half life (t½β), however, was similar for all three types of HES [from 332 (100) to 381 (63) min]. Conclusions. In low-substituted HES, molecular weight is not a key factor in compromising blood coagulation. The longer initial intravascular persistence of high molecular weight lowsubstituted HES might result in a longer lasting volume effect.
