The [Formula: see text] exchanger pendrin (SLC26A4, PDS) is located on the apical membrane of B-intercalated cells in the kidney cortical collecting duct and the connecting tubules and mediates the secretion of bicarbonate and the reabsorption of chloride. Given its dual function of bicarbonate secretion and chloride reabsorption in the ...

Simon Rippon has recently argued against kidney markets on the grounds that introducing the option to vend will result in many people, especially the poor, being subject to harmful pressure to vend. Though compelling, Rippon's argument fails. What he takes to be a single phenomenon-social and legal pressure to vend-is ...

Functioning paraganglioma is extra-adrenal catecholamine-secreting tumours that may cause secondary hypertension. Primary intrapericardial paragangliomas are very rare and are located adjacent to the great vessels or heart, typically near the left atrium. These tumours are an exceptionally uncommon finding during the investigation of refractory hypertension. However, in recent years, intrapericardial ...

Anxious attachment predicts strong desires for intimacy and stability in romantic relationships, yet the relation between anxious attachment and romantic commitment is unclear. We propose that extant literature has failed to find a consistent relation because anxiously attached individuals experience conflicting pressures on commitment. Data from Australia (N=137) show that ...

Gas pressure influences the regioselectivity and enantioselectivity of aryl alkene hydroformylation as catalyzed by rhodium complexes of the BisDiazaphos ligand. Deuterioformylation of styrene at 80 degrees C results in extensive deuterium incorporation into the terminal position of the recovered styrene. This result establishes that rhodium hydride addition to form a ...
