Genetic associations at 53 loci highlight cell types and biological pathways relevant for kidney function.

Reduced glomerular filtration rate defines chronic kidney disease and is associated with cardiovascular and all-cause mortality. We conducted a meta-analysis of genome-wide association studies for estimated glomerular filtration rate (eGFR), combining data across 133,413 individuals with replication in up to 42,166 individuals. We identify 24 new and confirm 29 previously identified loci. Of these 53 loci, 19 associate with eGFR among individuals with diabetes. Using bioinformatics, we show that identified genes at eGFR loci are enriched for expression in kidney tissues and in pathways relevant for kidney development and transmembrane transporter activity, kidney structure, and regulation of glucose metabolism. Chromatin state mapping and DNase I hypersensitivity analyses across adult tissues demonstrate preferential mapping of associated variants to regulatory regions in kidney but not extra-renal tissues. These findings suggest that genetic determinants of eGFR are mediated largely through direct effects within the kidney and highlight important cell types and biological pathways.

Explorations and comparisons of actual, ideal, and ought forgiveness definitions : a Q-methodological study /

Numerous definitions of forgiveness have been proposed in the literature (e.g.. North, 1987; Enright, Freedman & Rique, 1998), most ofwhich are based on religious or philosophical notions, rather than on empirical evidence. Definitions employed by researchers have typically set very high standards for forgiveness. This research was designed to investigate the possibility that these definitions describe an ideal of forgiveness and may not reflect laypersons' beliefe and experiences. Using Higgins' Self-Discrepancy Theory as a fiamework, three types of forgiveness beliefs were investigated: actual, ideal, and ought Q-methodology (which permits intensive study ofphenomena in small samples) was employed to examine and compare participants' beliefs about forgiveness across these domains. Thirty participants (20 women), 25 to 78 years of age, were recruited firom the community. They were asked to sort a set of66 statements about forgiveness according to their level of agreement with each statement This process was repeated three times, with the goal of modelling participants' actual experiences, their ideals, and how they believed forgiveness ought to be. Three perspectives on forgiveness emerged across the domains: forgiveness as motivated by religious beliefs, reconciliation-focussed forgiveness, and conflicted forgiveness. These perspectives indicated that, for many participants, the definitions presented in the literature may coincide with their beliefs about how forgiveness would ideally be and should be, as well as with their experiences of forgiveness; however, a large number of participants' experiences of, and beliefs about, forgiveness do not conform to the standards set out in the literature, and to exclude these participants' experiences and beliefs would mean overlooking what forgiveness means to a large portion of people. Results of this study indicate that researchers need to keep an open mind about what forgiveness may mean to their participants.

Les liens sociaux entre les dépendants et le maître/patron dans la Correspondance de Cicéron

Ce travail de recherche cherche à répondre à deux questions : Quels sont les liens sociaux liant les maîtres et ingénus aux dépendants, sont-ils plus importants entre ingénus et affranchis qu’entre ingénus et esclaves? Ont-ils une influence positive sur l’affranchissement des esclaves dans la Correspondance de Cicéron ? Cette étude évolue par thème, passant des liens amicaux, matrimoniaux, sexuels aux évaluations des maîtres et des patrons sur leurs esclaves et affranchis. Avant la conclusion, quelques pages seront également dévolues aux esclaves et affranchis absents de la Correspondance pour expliquer cette absence et les situer dans le contexte de la fin de la République romaine. L’étude des liens sociaux liant les dépendants aux maîtres, patrons et ingénus, dans une approche soulignant les liens amicaux, affectifs, maritaux et sexuels plutôt que les liens sociaux purement juridiques, a permis de prouver l’existence assez fréquente de liens amicaux et affectifs entre les dépendants (esclaves et affranchis) et les maîtres, les patrons et les ingénus dans la Correspondance. L’étude de la Correspondance démontre également que ses liens amicaux et affectifs étaient plus nombreux et plus soutenus entre affranchis et ingénus qu’entre ingénus et esclave, mettant en lumière l’importance des liens d’amitié et d’affection dans le processus d’affranchissement de certains esclaves.
