A Comparative Study: Service Animals and Emotional Support Animals under the Fair Housing Act and the Americans with Disabilities Act & An Overview of Assistance Animal Laws of Select States, April 18, 2010

The Americans with Disabilities Act (ADA) and the Fair Housing Act (FHA) prohibit discrimination on the basis of disability and govern the use of service or emotional support animals in places where pets may not be permitted. However, courts have been struggling with how to define and treat animals that qualify for protection under each law. This has created confusion as to what rights and duties are owed disabled persons and the animals that live with or accompany them. This essay attempts to clarify these two federal laws with regard to service or emotional support animals and the differing parties‘ rights and interests. It also includes an overview of select state laws that govern assistance animals of all types and our recommendations for enhancing the Iowa Civil Rights Act.

Investigation phytochimique d'une plante médicinale malgache Hypoestes serpens (Vahl) R. Br. (Acanthaceae) variété glabre et étude comparative avec la variété poilue

Résumé A Madagascar, comme dans plusieurs pays en développement, une grande partie de la population utilise les plantes pour se soigner. Plusieurs espèces des plantes sont ainsi utilisées en médecine traditionnelle malgache. Par ailleurs, la plupart de ces plantes ne font l'objet que de très peu d'étude scientifique. En effet, dans le cadre de l'investigation phytochimique de plantes utilisées en médecine traditionnelle malgache et dans la recherche des nouvelles substances biologiquement actives, Hypoestes serpens (Vahl) R. Br. (Acanthaceae) a été étudiée. Elle se présente sous deux variétés (glabre et poilue) qui sont tous utilisées dans la région sud-centre de Madagascar pour traiter la blennorragie. De l'extrait dichlorométhanique des feuilles de H. serpens (Vahl) R. Br. variété glabre, 12 diterpénoides dont 8 nouveaux ont été isolés. Ils ont tous montré une activité antifongique contre un champignon pathogène des plantes, Cladosporium cucumerinum, dans la bioautographie directe sur CCM. Quelques-uns ont également présenté une activité contre une levure saprophyte chez l'homme, Candida albicans et une activité inhibitrice de l'enzyme acétylcholinesterase. Les diterpènoïdes sont déjà considérés comme les principaux métabolites secondaires du genre Hypoestes. Le fractionnement de l'extrait méthanolique a conduit à l'isolement de 5 glycosides des flavonoïdes dont 4 sous formes C-g,lycosides qui n'ont jamais été identifiés dans la famille Acanthaceae. Ces flavonoïdes ont présenté une activité antiradicalaire contre le DPPH. Le fractionnement et la purification des extraits ont été effectués à l'aide des différentes techniques chromatographiques telles que la chromatographie sur colonne ouverte, la filtration sur gel, la chromatographie liquide à haute pression, la chromatographie liquide à moyenne pression et la chromatographie liquide à basse pression. Par ailleurs, les structures des composés isolés ont été élucidées par des techniques spectroscopiques (UV, MS, RMN) et de méthode chimique (hydrolyse acide). En plus de ces techniques, certaines méthodes physiques (cristallographie par rayons-X, mesure de rotation optique) ont été réalisées pour confirmer certaines structures. Comme l'espèce Hypoestes serpens (Vahl) R. Br. se présente en deux variétés, une étude comparative a été effectuée. Cette étude avait montré que ces deux variétés ont une activité biologique similaire. Finalement, une technique analytique couplée, HPLC-UV-APC1-MS a permis de montrer la présence de toutes les substances isolées de la variété glabre dans la variété poilue. Second résumé Depuis des milliers d'almées, l'homme utilise les plantes pour se soigner. De nos jours, même avec le développement de la médecine moderne, la phytothérapie reste toujours la forme des soins de santé abordable et accessible pour la majorité des populations rurales des pays en développement. En outre, les plantes médicinales constituent une source potentielle de molécules biologiquement actives pour les industries pharmaceutiques et actuellement, on estime que 25% des médicaments commercialisés dans le monde sont à base de plantes Dans le cadre de la recherche des nouvelles molécules à intérêt thérapeutique qui pourraient devenir un médicament ou un modèle de structure ("lead compound") pour le développement de nouveaux médicaments, nous avons fait une étude sur l'espèce, Hypoestes serpens (Vahl) R. Br, plante utilisée en médecine traditionnelle malgache. Cette espèce existe en deux variétés, une glabre et une autre poilue qui sont tous utilisées dans la région sud-centre de Madagascar pour traiter la blennorragie. Par ailleurs, les tradipraticiens utilisent de préférence la variété poilue. Dans la première partie de ce présent travail, une investigation phytochimique de H serpens, variété glabre (variété moins utilisée) a d'abord été effectuée afm d'isoler et d'identifier le maximum des molécules biologiquement actives qu'elle contient. De ce fait, 17 composés dont 8 nouveaux ont été isolés. Les potentiels d'activités thérapeutiques des substances isolées ont ensuite été dépistés sur les différents cibles suivants.: deux souches de champignons (Cladosporium cucumerinum et Candida albicans), l'enzyme acétylcholinesterase et le radical DPPH. La deuxième partie de ce travail a été consacrée sur l'étude comparative des deux variétés (glabre et poilue) de H. serpens à la fois sur le plan biologique et sur le plan phytochimique. A l'issue de cette comparaison, nous avons constaté que l'utilisation de ces deux variétés en médecine traditionnelle malgache n'est pas un hasard ; les deux variétés avaient présenté une activité biologique très remarquable et contiennent les mêmes substances actives. Ces résultats démontrent les potentiels thérapeutiques de H serpens en médecine traditionnelle malgache et pourraient également encourager les tradipraticiens à utiliser la variété glabre tout en protégeant la variété poilue qui est en voie de disparition actuellement. En bref, l'investigation phytochimique de H. serpens justifiée par l'isolement et l'identification de certains de ses principes actifs ouvre la voie aux recherches des médicaments d'origine naturelle. Abstract In Madagascar, as in many developing countries, most people use plants to cure. A large number of plant species are employed in Malagasy traditional medicine. Moreover, most of these plants have been subject only very little scientific study. As part of a phytochemical investigation of plants used in Malagasy traditional medicine and in the search for new biologically active substances, Hypoestes serpens (Vah1) R.Br. (Acanthaceae) was investigated. This species exists in two varieties (glabrous and hairy) which are used in the south-center part of Madagascar to treat gonorrhoea. From the dichloromethane extract of the leaves of H. serpens (Vah1) R. Br. glabrous variety, 12 diterpenoids 8 of which were new, were isolated. They showed antifungal activity against the plant pathogen Cladosporium cucumerinum, in the direct TLC bioautography. Some of them also had activity against the yeast Candida athicans and inhibited acetylcholinesterase. The diterpenes are considered as the principal secondary metabolites of the genus Hypoestes. Fractionation of the methanol extract led to the isolation of 5 flavonoid glycosides, 4 of which were C-glycosides, never before identified in the Acanthaceae family. These flavonoids showed radical scavenging activity against DPPH. The fractionation and the purification of the extracts were achieved by different chromatographic techniques such as open-column chromatography, gel filtration, high- pressure liquid chromatography, medium-pressure liquid chromatography and low-pressure liquid chromatography. Moreover, the structures of the isolated compounds were elucidated by spectroscopic techniques (UV, MS, NMR) and chemical technique (acid hydrolysis). In addition, some physical methods (X-ray crystallography, measurement of optical rotation) were performed to confirm some structures. As the species Hypoestes serpens (Vah1) R. Br. is present in two varieties, a comparative study was carried out. This study showed that these two varieties had similar biological activity. Finally, a coupled analytical technique HPLC-UV-APCI-MS showed the presence of the same compounds in both the glabrous and hairy varieties.

Effectiveness of a drug dosing service provided by community pharmacists in polymedicated elderly patients with renal impairment a comparative study

Background: Drug dosing errors are common in renal-impaired patients. Appropriate dosing adjustment and drug selection is important to ensure patients" safety and to avoid adverse drug effects and poor outcomes. There are few studies on this issue in community pharmacies. The aims of this study were, firstly, to determine the prevalence of dosing inadequacy as a consequence of renal impairment in patients over 65 taking 3 or more drug products who were being attended in community pharmacies and, secondly, to evaluate the effectiveness of the community pharmacist"s intervention in improving dosing inadequacy in these patients when compared with usual care. Methods: The study was carried out in 40 Spanish community pharmacies. The study had two phases: the first, with an observational, multicentre, cross sectional design, served to determine the dosing inadequacy, the drug-related problems per patient and to obtain the control group. The second phase, with a controlled study with historical control group, was the intervention phase. When dosing adjustments were needed, the pharmacists made recommendations to the physicians. A comparison was made between the control and the intervention group regarding the prevalence of drug dosing inadequacy and the mean number of drug-related problems per patient. Results: The mean of the prevalence of drug dosing inadequacy was 17.5% [95% CI 14.6-21.5] in phase 1 and 15.5% [95% CI 14.5-16.6] in phase 2. The mean number of drug-related problems per patient was 0.7 [95% CI 0.5-0.8] in phase 1 and 0.50 [95% CI 0.4-0.6] in phase 2. The difference in the prevalence of dosing inadequacy between the control and intervention group before the pharmacists" intervention was 0.73% [95% CI (−6.0) - 7.5] and after the pharmacists" intervention it was 13.5% [95% CI 8.0 - 19.5] (p < 0.001) while the difference in the mean of drug-related problems per patient before the pharmacists" intervention was 0.05 [95% CI( -0.2) - 0.3] and following the intervention it was 0.5 [95% CI 0.3 - 0.7] (p < 0.001). Conclusion: A drug dosing adjustment service for elderly patients with renal impairment in community pharmacies can increase the proportion of adequate drug dosing, and improve the drug-related problems per patient. Collaborative practice with physicians can improve these results.

Comparative study of upper lip frenectomy with the CO2 laser versus the Er, Cr: YSGG laser

Objectives: To compare upper lip frenulum reinsertion, bleeding, surgical time and surgical wound healing in frenectomies performed with the CO2 laser versus the Er, Cr:YSGG laser. Study design: A prospective study was carried out on 50 randomized pediatric patients who underwent rhomboidal resection of the upper lip frenulum with either the CO2 laser or the Er,Cr:YSGG laser. Twenty-five patients were assigned to each laser system. All patients were examined at 7, 14, 21 days and 4 months after the operation in order to assess the surgical wound healing. Results: Insertion of the frenulum, which was preoperatively located between the upper central incisors, migrated to the mucogingival junction as a result of using both laser systems in all patients. Only two patients required a single dose of 650 mg of paracetamol, one of either study group. CO2 laser registered improved intraoperative bleeding control results and shorter surgical times. On the other hand, the Er,Cr:YSGG laser achieved faster healing. Conclusions: Upper lip laser frenectomy is a simple technique that results in minimum or no postoperative swelling or pain, and which involves upper lip frenulum reinsertion at the mucogingival junction. The CO2 laser offers a bloodless field and shorter surgical times compared with the Er,Cr:YSGG laser. On the other hand, the Er,Cr:YSGG laser achieved faster wound healing.

Conclusion: A drug dosing adjustment service for elderly patients with renal impairment in community pharmacies can increase the proportion of adequate drug dosing, and improve the drug-related problems per patient. Collaborative practice with physicians can improve these results.

A new ambulatory system for comparative evaluation of the three-dimensional knee kinematics, applied to anterior cruciate ligament injuries

The aim of this study was to develop an ambulatory system for the three-dimensional (3D) knee kinematics evaluation, which can be used outside a laboratory during long-term monitoring. In order to show the efficacy of this ambulatory system, knee function was analysed using this system, after an anterior cruciate ligament (ACL) lesion, and after reconstructive surgery. The proposed system was composed of two 3D gyroscopes, fixed on the shank and on the thigh, and a portable data logger for signal recording. The measured parameters were the 3D mean range of motion (ROM) and the healthy knee was used as control. The precision of this system was first assessed using an ultrasound reference system. The repeatability was also estimated. A clinical study was then performed on five unilateral ACL-deficient men (range: 19-36 years) prior to, and a year after the surgery. The patients were evaluated with the IKDC score and the kinematics measurements were carried out on a 30 m walking trial. The precision in comparison with the reference system was 4.4 degrees , 2.7 degrees and 4.2 degrees for flexion-extension, internal-external rotation, and abduction-adduction, respectively. The repeatability of the results for the three directions was 0.8 degrees , 0.7 degrees and 1.8 degrees . The averaged ROM of the five patients' healthy knee were 70.1 degrees (standard deviation (SD) 5.8 degrees), 24.0 degrees (SD 3.0 degrees) and 12.0 degrees (SD 6.3 degrees for flexion-extension, internal-external rotation and abduction-adduction before surgery, and 76.5 degrees (SD 4.1 degrees), 21.7 degrees (SD 4.9 degrees) and 10.2 degrees (SD 4.6 degrees) 1 year following the reconstruction. The results for the pathologic knee were 64.5 degrees (SD 6.9 degrees), 20.6 degrees (SD 4.0 degrees) and 19.7 degrees (8.2 degrees) during the first evaluation, and 72.3 degrees (SD 2.4 degrees), 25.8 degrees (SD 6.4 degrees) and 12.4 degrees (SD 2.3 degrees) during the second one. The performance of the system enabled us to detect knee function modifications in the sagittal and transverse plane. Prior to the reconstruction, the ROM of the injured knee was lower in flexion-extension and internal-external rotation in comparison with the controlateral knee. One year after the surgery, four patients were classified normal (A) and one almost normal (B), according to the IKDC score, and changes in the kinematics of the five patients remained: lower flexion-extension ROM and higher internal-external rotation ROM in comparison with the controlateral knee. The 3D kinematics was changed after an ACL lesion and remained altered one year after the surgery

Comparative transcriptomics of extreme phenotypes of human HIV-1 infection and SIV infection in sooty mangabey and rhesus macaque.

High levels of HIV-1 replication during the chronic phase of infection usually correlate with rapid progression to severe immunodeficiency. However, a minority of highly viremic individuals remains asymptomatic and maintains high CD4+ T cell counts. This tolerant profile is poorly understood and reminiscent of the widely studied nonprogressive disease model of SIV infection in natural hosts. Here, we identify transcriptome differences between rapid progressors (RPs) and viremic nonprogressors (VNPs) and highlight several genes relevant for the understanding of HIV-1-induced immunosuppression. RPs were characterized by a specific transcriptome profile of CD4+ and CD8+ T cells similar to that observed in pathogenic SIV-infected rhesus macaques. In contrast, VNPs exhibited lower expression of interferon-stimulated genes and shared a common gene regulation profile with nonpathogenic SIV-infected sooty mangabeys. A short list of genes associated with VNP, including CASP1, CD38, LAG3, TNFSF13B, SOCS1, and EEF1D, showed significant correlation with time to disease progression when evaluated in an independent set of CD4+ T cell expression data. This work characterizes 2 minimally studied clinical patterns of progression to AIDS, whose analysis may inform our understanding of HIV pathogenesis.

Phylogeography and recolonization of the Swiss Alps by the Valais shrew (Sorex antinorii), inferred with autosomal and sex-specific markers.

Using one male-inherited, one female-inherited and eight biparentally inherited markers, we investigate the population genetic structure of the Valais shrew (Sorex antinorii) in the Swiss Alps. Bayesian analysis on autosomal microsatellites suggests a clear genetic differentiation between two groups of populations. This geographically based structure is consistent with two separate postglacial recolonization routes of the species into Switzerland from Italian refugia after the last Pleistocene glaciations. Sex-specific markers also confirm genetic structuring among western and eastern areas, since very few haplotypes for either Y chromosome or mtDNA genome are shared between the two regions. Overall, these results suggest that two already well-differentiated genetic lineages colonized the Swiss Alps and came into secondary contact in the Rhône Valley. Low level of admixture between the two lineages is likely explained by the mountainous landscape structure of lateral valleys orthogonal to the main Rhône valley.

Comparative genome analysis of Pseudomonas knackmussii B13, the first bacterium known to degrade chloroaromatic compounds.

Pseudomonas knackmussii B13 was the first strain to be isolated in 1974 that could degrade chlorinated aromatic hydrocarbons. This discovery was the prologue for subsequent characterization of numerous bacterial metabolic pathways, for genetic and biochemical studies, and which spurred ideas for pollutant bioremediation. In this study, we determined the complete genome sequence of B13 using next generation sequencing technologies and optical mapping. Genome annotation indicated that B13 has a variety of metabolic pathways for degrading monoaromatic hydrocarbons including chlorobenzoate, aminophenol, anthranilate and hydroxyquinol, but not polyaromatic compounds. Comparative genome analysis revealed that B13 is closest to Pseudomonas denitrificans and Pseudomonas aeruginosa. The B13 genome contains at least eight genomic islands [prophages and integrative conjugative elements (ICEs)], which were absent in closely related pseudomonads. We confirm that two ICEs are identical copies of the 103 kb self-transmissible element ICEclc that carries the genes for chlorocatechol metabolism. Comparison of ICEclc showed that it is composed of a variable and a 'core' region, which is very conserved among proteobacterial genomes, suggesting a widely distributed family of so far uncharacterized ICE. Resequencing of two spontaneous B13 mutants revealed a number of single nucleotide substitutions, as well as excision of a large 220 kb region and a prophage that drastically change the host metabolic capacity and survivability.

A Comparative Policy Analysis of Seat Belt Laws, RB37-013, 2014

This analysis examined data from a variety of sources to estimate the benefit of enhancing Iowa’s current law to require all passengers to use seat belts. In addition to assessing Iowans’ opinions about changing the law, a literature review, a legislative policy review, and analysis of Iowa crash data were completed. Currently 28 states enforce seat belt laws for all passengers. Belted passengers riding with an unbelted passenger are 2 to 5 times more likely to suffer fatal injuries in a crash relative to when all occupants are using seat belts. Iowans are highly compliant (90%-94%) with the current seat belt law for front seat occupants. Of more than 1000 Iowans surveyed, 85% said they always use a seat belt when riding in the front seat, but only 36% always do so when they ride in the back seat. The most common reasons given for not using seat belts in the back seat are forgetting to buckle up and because it is not the law. Iowans widely support strengthening Iowa’s seat belt law — 62% said Iowa law should require all rear seat passengers to use seat belts. Four out of five respondents said they would use seat belts more often when sitting in the rear seat if it was the law. It is estimated rear seat fatalities would decrease about 48%, from 13 to 7 fatalities annually, if an all-passenger law was implemented in Iowa.

Correction chirurgicale de la tétralogie de Fallot étude comparative de deux méthodes

La survie actuelle après correction chirurgicale de la Tétralogie de Fallot (TDF) est de 97% à 12 ans. Les principaux risques à long terme sont une régurgitation pulmonaire ou une sténose récidivante de la sortie droite du coeur, une tachycardie ventriculaire pouvant entrainer une mort subite. Le but de cette étude rétrospective est de comparer la correction chirurgicale de la TDF avec patch pulmonaire versus un conduit valvé xénogreffe. Le collectif se compose de 127 patients entre 2 mois et 16 ans, opérés pour une TDF entre l'année 2000 et 2010. La correction chirurgicale était soit avec un patch, soit avec un conduit valvé à la sortie droite. Cette étude montre d'une part qu'il n'y a pas de différence de survie à un mois entre les deux méthodes opératoires. De plus, elle montre que, lors de la pose d'un patch, il y a plus de sept fois plus d'insuffisances valvulaires modérées à sévères après un mois que lors de la pose d'un conduit valvé. D'autre part, elle démontre que la différence de gradient résiduel à la sortie droite entre la correction avec patch ou conduit n'est pas significative et que la valeur du gradient résiduel à la sortie droite en postopératoire n'est pas représentative du gradient résiduel à un mois. De plus, cette étude prouve que les coronaires aberrantes ainsi qu'un shunt palliatif de Blalock-Taussig sont des facteurs de risque indépendants pour une correction avec un conduit valvé.

Determination of 241Pu in nuclear waste slurries: a comparative study using LSC and ICP-MS.

(241)Pu was determined in slurry samples from a nuclear reactor decommissioning project at the Paul Scherrer Institute (Switzerland). To validate the results, the (241)Pu activities of five samples were determined by LSC (TriCarb and Quantulus) and ICP-MS, with each instrument at a different laboratory. In lack of certified reference materials for (241)Pu, the methods were further validated using the (241)Pu information values of two reference sediments (IAEA-300 and IAEA-384). Excellent agreement with the results was found between LSC and ICP-MS in the nuclear waste slurries and the reference sediments.

Multilocus phylogeography of the common lizard Zootoca vivipara at the Ibero-Pyrenean suture zone reveals lowland barriers and high-elevation introgression.

BACKGROUND: The geographic distribution of evolutionary lineages and the patterns of gene flow upon secondary contact provide insight into the process of divergence and speciation. We explore the evolutionary history of the common lizard Zootoca vivipara (= Lacerta vivipara) in the Iberian Peninsula and test the role of the Pyrenees and the Cantabrian Mountains in restricting gene flow and driving lineage isolation and divergence. We also assess patterns of introgression among lineages upon secondary contact, and test for the role of high-elevation trans-mountain colonisations in explaining spatial patterns of genetic diversity. We use mtDNA sequence data and genome-wide AFLP loci to reconstruct phylogenetic relationships among lineages, and measure genetic structure RESULTS: The main genetic split in mtDNA corresponds generally to the French and Spanish sides of the Pyrenees as previously reported, in contrast to genome-wide AFLP data, which show a major division between NW Spain and the rest. Both types of markers support the existence of four distinct and geographically congruent genetic groups, which are consistent with major topographic barriers. Both datasets reveal the presence of three independent contact zones between lineages in the Pyrenean region, one in the Basque lowlands, one in the low-elevation mountains of the western Pyrenees, and one in the French side of the central Pyrenees. The latter shows genetic evidence of a recent, high-altitude trans-Pyrenean incursion from Spain into France. CONCLUSIONS: The distribution and age of major lineages is consistent with a Pleistocene origin and a role for both the Pyrenees and the Cantabrian Mountains in driving isolation and differentiation of Z. vivipara lineages at large geographic scales. However, mountain ranges are not always effective barriers to dispersal, and have not prevented a recent high-elevation trans-Pyrenean incursion that has led to asymmetrical introgression among divergent lineages. Cytonuclear discordance in patterns of genetic structure and introgression at contact zones suggests selection may be involved at various scales. Suture zones are important areas for the study of lineage formation and speciation, and our results show that biogeographic barriers can yield markedly different phylogeographic patterns in different vertebrate and invertebrate taxa.
