Licorice-induced hypertension and common variants of genes regulating renal sodium reabsorption.

AIM: To study if gene alterations affecting renal sodium reabsorption associate with susceptibility to licorice-induced hypertension.METHODS: Finnish subjects (n = 30) with a previously documented incident of licorice-induced hypertension were recruited for the study using a newspaper announcement. Their previous clinical and family histories as well as serum electrolyte levels were examined. DNA samples from all individuals were screened for variants of the genes encoding 11beta-hydroxysteroid dehydrogenase type 2 (11betaHSD2) and alpha-, beta-, and gamma-subunits of the epithelial sodium channel (ENaC).RESULTS: Upon licorice predisposition, the patients had a mean blood pressure of 201/118 mmHg. Circulating potassium, renin, and aldosterone levels were low. No significant DNA variations were identified in the 11betaHSD2 gene. Four subjects were heterozygous for beta- and gammaENaC variants previously shown to be associated with hypertension. Furthermore, a novel G insertion (2004-2005insG) in the SCNN1A gene encoding the alphaENaC was identified in two subjects. The frequency of these ENaC variants was significantly higher in subjects with licorice-induced hypertension (6/30 i.e. 20%) than in blood donors (11/301 i.e. 3.7%, P = 0.002).CONCLUSIONS: Defects of the 11betaHSD2 gene do not constitute a likely cause for licorice-induced hypertension. Variants of the ENaC subunits may render some individuals sensitive to licorice-induced metabolic alterations and hypertension.

Sustainability of the Peruvian anchoveta supply chains from sea to shelf: towards a new strategy for optimal use of resources

The research performed a sustainability assessment of supply chains of the anchoveta (Engraulis ringens) in Peru. The corresponding fisheries lands 6.5 million t per year, of which <2% is rendered into products for direct human consumption (DHC) and 98% reduced into feed ingredients (fishmeal and fish oil, FMFO), for export. Several industries compete for the anchoveta resources, generating local and global impacts. The need for understanding these dynamics, towards sustainability-improving management and policy recommendations, determined the development of a sustainability assessment framework: 1) characterisation and modelling of the systems under study (with Life Cycle Assessment and other tools) including local aquaculture, 2) calculation of sustainability indicators (i.e. energy efficiency, nutritional value, socio-economic performances), and 3) sustainability comparison of supply chains; definition and comparison of alternative exploitation scenarios. Future exploitation scenarios were defined by combining an ecosystem and a material flow models: continuation of the status quo (Scenario 1), shift towards increased proportion of DHC production (Scenario 2), and radical reduction of the anchoveta harvest in order for other fish stocks to recover and be exploited for DHC (Scenario 3). Scenario 2 was identified as the most sustainable. Management and policy recommendations include improving of: controls for compliance with management measures, sanitary conditions for DHC, landing infrastructure for small- and medium-scale (SMS) fisheries; the development of a national refrigerated distribution chain; and the assignation of flexible tolerances for discards from different DHC processes.

Common genetic variation and the control of HIV-1 in humans.

To extend the understanding of host genetic determinants of HIV-1 control, we performed a genome-wide association study in a cohort of 2,554 infected Caucasian subjects. The study was powered to detect common genetic variants explaining down to 1.3% of the variability in viral load at set point. We provide overwhelming confirmation of three associations previously reported in a genome-wide study and show further independent effects of both common and rare variants in the Major Histocompatibility Complex region (MHC). We also examined the polymorphisms reported in previous candidate gene studies and fail to support a role for any variant outside of the MHC or the chemokine receptor cluster on chromosome 3. In addition, we evaluated functional variants, copy-number polymorphisms, epistatic interactions, and biological pathways. This study thus represents a comprehensive assessment of common human genetic variation in HIV-1 control in Caucasians.

Genetic and maternal contributions to offspring viability under different environmental conditions in various salmonids

Summary : Due to anthropogenic impacts and natural fluctuations, fish usually have to cope with constantly changing and often hostile environments. Whereas adult fish have various possibilities to counteract unfavourable environmental conditions, embryos have much fewer options. Besides by their developing immune system, they are protected by the egg envelopes and several immune substances provided by their mothers. In addition to this, they may also adjust their hatching timing in reaction to various risks. However, individuals may vary in their defensive potential. This variation may be either based on their genetics and/or on differential maternal investments and may be dependent on the experienced stress. Nevertheless, in fish, the impact of such parental contributions on embryo and/or juvenile viability is still poorly investigated. The main objective of this thesis was to investigate the importance of paternal (i.e. genetic) and maternal (i.e. genetic + egg investment) contributions to offspring viability under different environmental conditions and at different life stages. In order to investigate this, we used gametes of various salmonids for in vitro fertilisation experiments based on full-factorial breeding designs. The individual studies are summarised in the following chapters: In the first chapter, we tested the effectiveness of the embryonic immune system in Lake whitefish (Coregonus palaea). Namely, we investigated paternal and maternal contributions to the embryos' tolerance to different kinds of pathogen exposure. Additionally, we tested whether an early sub-léthal exposure has a positive or a negative effect on an embryo's susceptibility to later pathogen exposures with the same pathogen. We found that pre-challenged embryos were more susceptible to future challenges. Moreover, pathogen susceptibility was dependent on maternal investments and/or the embryos' own genetics, depending on the challenge level. Chapter 2 summarises a similar study with brown trout (Salmo trutta). In addition to the previously described investigations, we analysed if genetic effects on offspring viability are mediated either by parental MHC genotypes or relatedness based on neutral microsatellite markers, and we tested if males signal their genetic quality either by their body size or their melanin-based skin colouration. We found that embryo survival was lower at higher stress levels and dependent on the embryos' genetics. Addirionally, parents with similar and/or, very common MHC genotypes had higher offspring viabilities. Finally, darker males produced more viable offspring. In the first two chapters we investigated the embryos' defensive potential based on their immune system, i.e. their pathogen tolerance. In chapter 3 we investigate whether hatching timing of Lake whitefìsh (C. palaea) is dependent on parental contributions and/or on pathogen pressure, and whether there are parental-environmental interactions. We found that whitefish embryos hatch earlier under increasing pathogen pressure. Moreover, hatching timing was affected by embryo genetics and/or maternally provided resources, but the magnitude of the effect was dependent on the pathogen. pressure. We also found a significant paternal-environmental interaction, indicating that the hatching efficiency of a certain sib group is dependent on the pathogen environment. Chapter 4 describes an analogous study with brown trout (S. trutta), with similar findings. In the former chapters, we only looked at offspring performance during the embryonic period, and only under semi-natural conditions. In chapter 5 we now test the performance and viability of embryonic and juvenile brown trout (S. trutta) under natural conditions. To measure embryo viability, we put them in brood boxes, buried them in the gravel of a natural river, and analysed survival after several months. To investigate juvenile survival and performance, wé reared embryos under different stress levels in the laboratory and subsequently released the resulting hatchlings in to a closed river section. Juvenile size and survival was then determined one year later. Additionally, we investigated if sires differ in their genetic quality, determined by embryo and juvenile survival as well as juvenile size, and if they signal their quality by either body size or melanin-based body darkness. We found hat juvenile size was dependent on genetic effects and on maternal investment, whereas this was neither the case for embryo nor for juvenile survival. Additionally, we found that offspring of darker males grew larger, and larger juveniles had also an increased survival. Finally, we found acarry-over effect of the early non-lethal challenge: exposing embryos to higher stress levels resulted in smaller juveniles. To evaluate the long-term performance of differently treated groups, mark-recapture studies are inevitable. For this purpose, effective mass-marking techniques are essential. In chapter 6 we tested the suitability of the fluorescent pigment spray marking method for the mass marking of European graylings (Thymallus thymallus), with very promising results. Our in vitro fertilisation studies on whitefish may reveal new insights on potential genetic benefits of mate choice, but the mating system of whitefish under natural conditions is still poorly investigated. In order to study this, we installed underwater cameras at the spawning place of a Coregonus suidteri population, recorded the whole mating period and subsequently analysed the recordings. Confirmations of previous findings as well as exciting new observations are listed and discussed in chapter 7. Dus aux impacts anthropogéniques et aux fluctuations naturelles, les poissons doivent faire face à des environnements en perpétuel changement. Ces changements font que les poissons doivent s'adapter à de nouvelles situations, souvent hostiles pour eux. Les adultes ont différentes possibilités d'échapper à un environnement peu favorable, ce n'est par contre pas le cas des embryons. Les embryons sont protégés d'une part par leur système immunitaire en développement, d'autre part, par la coquille de l'eeuf et différentes substances immunitaires fournies par leur mère. De plus, ils sont capables d'influencer leur propre date d'éclosion en réponse à différents facteurs de stress. Malgré tout, les individus varient dans leur capacité à se défendre. Cette variation peut être basé sur des facteurs génétiques et/ou sur des facteurs maternels, et est dépendante du stress subi. Néanmoins, chez les poissons, l'impact de telles contributions parentales sur la survie d'embryons et/ou juvéniles est peu étudié. L'objectif principal de cette thèse a été d'approfondir les connaissances sur l'importance de la contribution paternelle (c.a.d. génétique) et maternelle (c.a.d. génétique + investissement dans l'oeuf) sur la survie des jeunes dans différentes conditions expérimentales et stades de vie. Pour faire ces analyses, nous avons utilisé des gamètes de divers salmonidés issus de croisements 'full-factorial'. Les différentes expériences sont résumées dans les chapitres suivants: Dans le premier chapitre, nous avons testé l'efficacité du système immunitaire des embryons chez les corégones (Coregonus palea). Plus précisément nous avons étudié la contribution paternelle et maternelle à la tolérance des embryons à différents niveaux de stress pathogène. Nous avons aussi testé, si une première exposition non létale à un pathogène avait un effet positif ou négatif sur la susceptibilité d'un embryon a une deuxième exposition au même pathogène. Nous avons trouvé que des embryons qui avaient été exposés une première fois étaient plus sensibles au pathogène par la suite. Mais aussi que la sensibilité au pathogène était dépendante de l'investissement de la mère et/ou des gènes de l'embryon, dépendamment du niveau de stress. Le deuxième chapitre résume une étude similaire avec des truites (Salmo truffa). Nous avons examiné, si la survie des jeunes variait sous différentes intensités de stress, et si la variance observée était due aux gènes des parents. Nous avons aussi analysé si les effets génétiques sur la survie des juvéniles étaient dus au MHC (Major Histocompatibility Complex) ou au degré de parenté des parents. De plus, nous avons analysé si les mâles signalaient leur qualité génétique par la taille du corps ou par leur coloration noire, due à la mélanine. On a trouvé que la survie des embryons était plus basse quand le niveau de stress était plus haut mais que la variation restait dépendante de la génétique des embryons. De plus, les parents avec des MHC similaires et/ou communs avaient des embryons avec une meilleure survie. Par contre, des parents avec un degré de parenté plus haut produisent des embryons avec une survie plus mauvaise. Finalement nous avons montré que les mâles plus foncés ont des embryons qui survivent mieux, mais que la taille des mâles n'a pas d'influence sur la survie de ces mêmes embryons. Dans les deux premiers chapitres, nous avons étudié le potentiel de défense des embryons basé sur leur système immunitaire, c.a.d. leur tolérance aux pathogènes. Dans le troisième chapitre, nous nous intéressons à la date d'éclosion des corégones (C. palea), pour voir si elle est influencée par les parents ou par la pression des pathogènes, et si il y a une interaction entre ces deux facteurs. Nous avons trouvé que les jeunes naissent plus rapidement lorsque la pression en pathogènes augmente. La date d'éclosion est influencée par la génétique des embryons et/ou l'investissement des parents, mais c'est la magnitude des effets qui est dépendante de la pression du pathogène. Nous avons aussi trouvé une interaction entre l'effet paternel et l'environnement, ce qui indique que la rapidité d'éclosion de certains croisements est dépendante des pathogènes dans l'environnement. Le chapitre 4 décrit une étude analogue avec de truites (S. truffa), avec des résultats sitzimilaires. Dans les précédents chapitres nous nous sommes uniquement concentrés sur les performances des jeunes durant leur stade embryonnaire, et seulement dans des conditions semi naturelles. Dans le chapitre 5 nous testons la performance et la viabilité des embryons et de juvéniles de truites (S. truffa) dans des conditions naturelles. Nous avons trouvé que la taille des juvéniles était dépendante d'effets génétiques et de l'investissement maternel, mais ceci n'était ni les cas pour les survie des embryons et des juvéniles. De plus, nous avons trouvé que les jeunes des mâles plus foncés devenaient plus grands et que les grands ont un meilleur taux de survie. Finalement nous avons trouvé un 'carry-over effect' d'une première exposition non létale à un pathogène: exposer des embryons à des plus hauts niveaux de stress donnait des juvéniles plus petits. Pour évaluer la performance à long terme de groupes traités dé manières différentes, une méthode de marquage-recapture est inévitable. Pour cette raison, des techniques de marquage en masse sont nécessaires. Dans le chapitre 6, nous avons testé l'efficacité de la technique `fluorescent pigment spray marking' pour le marquage en masse de l'Ombre commun (Thymallus thymallus), avec des résultats très prometteurs. Les études de fertilisations in vitro avec les corégones nous donnent une idée du potentiel bénéfice génétique que représente la sélection d'un bon partenaire, même si le système d'accouplement des corégones en milieu naturel reste peu connu. Pour combler cette lacune, nous avons installé des caméras sous-marines autour de la frayère d'une population de corégones (C. suidteri), nous avons enregistré toute la période de reproduction et nous avons analysé les données par la suite. Ainsi, nous avons été capables de confirmer bien des résultats trouvés précédemment, mais aussi de faire de nouvelles observations. Ces résultats sont reportés dans le septième chapitre, où elles sont comparées avec des observations antérieures.

Consultoria del procés de logística interna del laboratori d'anàlisis clíniques a l'Hospital General de Vic

Com a resultat de les politiques i estratègies de col·laboració entre la universitat de Vic i de l’hospital i de la voluntat de realitzar activitats formatives conjuntes , s’estableix un línia de treball orientada a l’estudi i anàlisi de la situació logística interna actual del laboratori d’anàlisis clíniques de l’Hospital General de Vic. El treball es centra en el procés intern del laboratori i l’abast de l’estudi es troba limitat a les àrees especifiques d’hematologia i coagulació i bioquímica. D’aquestes dues àrees el treball realitza un estudi exhaustiu del seu procés intern, identifica les seves activitats i la seva metodologia de treball amb l’objectiu d’elaborar el Value Stream Map de cadascuna de les àrees. Les àrees de Microbiologia, Banc de Sang i Urgències resten fora d’aquest estudi exhaustiu tot i que són presents en el treball per la inevitable interacció que tenen en la globalitat del procés. El treball es centra bàsicament en els processos automatitzats tot i que els processos que es duen a terme en el laboratori són tant automatitzats com manuals. També es limita al sistema productiu intern del laboratori tot i la interacció que té aquest sistema intern amb altres centres productius del sistema com ara són els centres d’atenció primària, els diversos hospitals i centres d’atenció sociosanitària. El laboratori es troba immers en el moment de l’elaboració d’aquest treball en un situació de canvi i millora del seus processos interns que consisteixen principalment en la substitució de part la maquinària actual que obliguen a la definició d’un nou layout i d’una nova distribució de la producció a cada màquina. A nivell extern també s’estan produint millores en el sistema informàtic de gestió que afecten a part del seu procés. L’objectiu del treball és donar visibilitat total al procés de logística interna actual del laboratori, identificant clarament com són i quina seqüència tenen els processos logístics interns i els mètodes de treball actuals, tant de recursos màquina com recursos persona, per poder identificar sota una perspectiva de generació de valor, aquells punts concrets de la logística interna que poden ser millorats en quant a eficiència i productivitat amb l’objectiu que un cop identificats es puguin emprendre accions i/o projectes de millora. El treball finalitza amb un anàlisis final del procés logística interna des d’una òptica Lean. Per fer-ho, identifica aquelles activitats que no aporten valor al procés o MUDA i les classifica en set categories i es realitzen diverses propostes de millora com són la implantació d’un flux continu , anivellat i basat en un concepte pull , identifica activitats que poden ser estandarditzades i/o simplificades i proposa modificacions en les infraestructures físiques per donar major visibilitat al procés. L’aspecte humà del procés es planteja des d’un punt de vist de metodologia, formació, comunicació i aplicació de les 5S.

Occurrence of common scab in potato tubers following foliar treatment with glycinebetaine under glasshouse conditions

Defecto en la homeostasis del oxido nítrico. Mecanismo común subyacente de la insulino-resistencia, la hiperactividad simpática y la morbi-mortalidad cardiovascular [Defective nitric oxide homeostasis. Common underlying mechanism between insulin resistance, sympathetic overactivity and cardiovascular morbidity and mortality]

Obesity, insulin resistance and associated cardiovascular complications are reaching epidemic proportions worldwide and represent a major public health problem. Over the past decade, evidence has accumulated indicating that insulin administration, in addition to its metabolic effects, also has important cardiovascular actions. The sympathetic nervous system and the L-arginine-nitric oxide pathway are the central players in the mediation of insulin's cardiovascular actions. Based on recent animal and human research, we demonstrate that both defective and augmented NO synthesis represent a central defect triggering many of the metabolic, vascular and sympathetic abnormalities characteristic of insulin-resistant states. These observations provide the rationale for the use of pharmaceutical drugs releasing small and physiological amounts of NO and/or inhibitors of NO overproduction as a future treatment for insulin resistance and associated comorbidities.

Understanding informal payments in health care: motivation of health workers in Tanzania

BACKGROUND: There is growing evidence that informal payments for health care are fairly common in many low- and middle-income countries. Informal payments are reported to have a negative consequence on equity and quality of care; it has been suggested, however, that they may contribute to health worker motivation and retention. Given the significance of motivation and retention issues in human resources for health, a better understanding of the relationships between the two phenomena is needed. This study attempts to assess whether and in what ways informal payments occur in Kibaha, Tanzania. Moreover, it aims to assess how informal earnings might help boost health worker motivation and retention. METHODS: Nine focus groups were conducted in three health facilities of different levels in the health system. In total, 64 health workers participated in the focus group discussions (81% female, 19% male) and where possible, focus groups were divided by cadre. All data were processed and analysed by means of the NVivo software package. RESULTS: The use of informal payments in the study area was confirmed by this study. Furthermore, a negative relationship between informal payments and job satisfaction and better motivation is suggested. Participants mentioned that they felt enslaved by patients as a result of being bribed and this resulted in loss of self-esteem. Furthermore, fear of detection was a main demotivating factor. These factors seem to counterbalance the positive effect of financial incentives. Moreover, informal payments were not found to be related to retention of health workers in the public health system. Other factors such as job security seemed to be more relevant for retention. CONCLUSION: This study suggests that the practice of informal payments contributes to the general demotivation of health workers and negatively affects access to health care services and quality of the health system. Policy action is needed that not only provides better financial incentives for individuals but also tackles an environment in which corruption is endemic.

Genome-wide association study to identify common variants associated with brachial circumference: a meta-analysis of 14 cohorts.

Brachial circumference (BC), also known as upper arm or mid arm circumference, can be used as an indicator of muscle mass and fat tissue, which are distributed differently in men and women. Analysis of anthropometric measures of peripheral fat distribution such as BC could help in understanding the complex pathophysiology behind overweight and obesity. The purpose of this study is to identify genetic variants associated with BC through a large-scale genome-wide association scan (GWAS) meta-analysis. We used fixed-effects meta-analysis to synthesise summary results across 14 GWAS discovery and 4 replication cohorts comprising overall 22,376 individuals (12,031 women and 10,345 men) of European ancestry. Individual analyses were carried out for men, women, and combined across sexes using linear regression and an additive genetic model: adjusted for age and adjusted for age and BMI. We prioritised signals for follow-up in two-stages. We did not detect any signals reaching genome-wide significance. The FTO rs9939609 SNP showed nominal evidence for association (p<0.05) in the age-adjusted strata for men and across both sexes. In this first GWAS meta-analysis for BC to date, we have not identified any genome-wide significant signals and do not observe robust association of previously established obesity loci with BC. Large-scale collaborations will be necessary to achieve higher power to detect loci underlying BC.
