46 Autoregulation of renal blood flow (RBF) is an essential function of the renal 47 microcirculation that has been previously shown to be blunted by excessive dietary salt. 48 Endogenous endothelin 1 (ET-1) is increased following a high salt (HS) diet and 49 contributes to the control of RBF but the differential effects of ET-1 on renal microvessel 50 autoregulation in response to HS remain to...

Acute stress in both rodents and humans causes a transient rise in blood pressure associated with an increase in plasma endothelin-1 (ET-1). High salt (HS) intake also increases ET-1 production, and interestingly, blunts the pressor response to acute air jet stress in rats. We previously reported that female rats lacking functional ETB receptors everywhere except sympathetic nerves (ETB def) ha...

BACKGROUND The renal medullary endothelin (ET-1) system plays an important role in the control of sodium excretion and arterial pressure (AP) through the activation of renal medullary ET-B receptors. We have previously shown that blockade of endothelin type B receptors (ET-B) leads to salt-sensitive hypertension through mechanisms that are not fully understood. One possible mechanism is through...

Sir, We read with interest the study of Coras et al. (2014) reporting the absence of verbal anterograde episodic memory (AEM) impairment in patients with mesial temporal lobe epilepsy (MTLE) with a hippocampal sclerosis ILAE type 2 classification (HS ILAE 2, i.e. CA1 predominant cell loss). This finding may provide an anatomical basis for the dissociation of anterograde/long-term episodic memor...

BACKGROUND Circulating N-terminal pro-B-type natriuretic peptide (NT pro-BNP), high- sensitivity C-reactive protein (hs-CRP) and big endothelin (big-ET) have been shown to be increased in heart failure and to contribute to both hemodynamic deterioration and cardiovascular remodeling. Here, we examined the prognostic value of the three neurohormones at admission in a population of hospitalized p...

To the Editor: Last year, Ockene et al. (1) published a report in this journal that made the claim that high-sensitivity C-reactive protein (hs-CRP) has a degree of measurement stability that is similar to that of total cholesterol and that this provides further evidence of the potential clinical utility of hs-CRP screening as a novel tool for vascular risk prediction. The key evidence that Ock...

Clinical studies have documented an abrupt rise in plasma endothelin-1 (ET-1) coincident with an increase in mean arterial pressure (MAP) during the response to acute stress. We therefore examined the ET(A) and ET(B) receptor-dependent effects of ET-1 on the pressor response to acute environmental stress in ET-1-dependent hypertension. Stress was induced by administration of air jet pulses (3 m...

Awareness is increasing that there is phenotypic heterogeneity within the hidradenitis suppurativa (HS) disease spectrum. However, the few randomized HS trials that are available have not distinguished between the subtypes of the disease. In this issue, Canoui-Poitrine et al. used latent class (LC) analysis of the largest HS cohort described to date to generate three phenotypic subtypes. LC 1 c...
