Background: It has been postulated that chronic kidney disease (CKD) is a state of relative 11β-hydroxysteroid dehydrogenase type 2 (11βHSD2) insufficiency, resulting in increased cortisol-mediated mineralocorticoid receptor (MR) activation. We hypothesized that relative 11βHSD2 insufficiency manifests across a wide spectrum of progressively declining kidney function, including within the normal range.
Methods: Adult participants were recruited at two academic centers.
Article Synopsis
- * Researchers conducted a study with 206 adults to assess the relationship between low cortisone levels and low renin activity, which could indicate kidney and vascular damage.
- * Findings revealed that low cortisone significantly predicts low renin conditions and correlates with increased markers of renal harm, suggesting that low cortisone should be factored into assessments for more accurate diagnosis of PA.
The global decline of terrestrial species is largely due to the degradation, loss and fragmentation of their habitats. The conversion of natural ecosystems for cropland, rangeland, forest products and human infrastructure are the primary causes of habitat deterioration. Due to the paucity of data on the past distribution of species and the scarcity of fine-scale habitat conversion maps, however, accurate assessment of the recent effects of habitat degradation, loss and fragmentation on the range of mammals has been near impossible.

Objectives: The objective of this study was to compare the diurnal variations in cortisol and cortisone concentrations in serum and saliva among extremely preterm (EPT), very preterm (VPT), and full-term (FT) children, all born appropriate for gestational age (AGA).
Methods: EPT, VPT, and FT children, all born AGA, were recruited from two healthcare centers. Cortisol and cortisone concentrations in serum and saliva were measured by liquid chromatography-mass spectrometry (LC‒MS).
Background: Mild secretion defects are the most frequent and challenging blood platelet disorders to diagnose. Most δ-granule secretion tests lack validation, are not quantitative, or have unreliable response to weak platelet agonists.
Objectives: To compare platelet serotonin secretion by HPLC-electrochemical detection technique (HPLC-ECD) with the reference isotopic test (H-5-HT), evaluating its performance in clinical laboratories.
